Enhanced Coding Method by Remapping of Integral Images
Kim, Su-Bin ; Kang, Hyun-Soo ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 1~10
DOI : 10.5392/JKCA.2015.15.02.001
In this paper, we propose an integral image compression method to improve the coding efficiency. As the characteristics of integral images are various according to the distance between a camera and objects, complexity of the objects and background, etc, the coding efficiency can be improved by applying a coding method adaptive to the characteristics. In addition, as the integral images are compressed by the unit of elemental images, the coding efficiency can be improved. by employing a coding method optimized to the coding direction of elemental images. Therefore, the proposed method remaps an integral image with six kinds of mapping rules, and then the conventional 3D-DCT based compression method is applied to the remapped images. Finally, we perform the rate-distortion optimization to choose the best of the mapping rules. Experimental results show that the proposed method yields high gains in image quality and bit-rate.

DOI : 10.5392/JKCA.2015.15.02.011
In this paper, we develop an intelligent mobile surveillance system based on binary CDMA for the unmanned automatic tracking and surveillance. That is, we implement a intelligent surveillance system using the binary CDMA wireless communication technology which is applied the merit of CDMA and TDMA on it complexly. This system is able to monitor the site of the accident on network in real time and process the various situations by implementing the security surveillance system. This system pursues an object by the 360-degree using camera, expands image using a PTZ(Pan/Tilt/Zoom) camera zooming function, identifies the mobile objects image within a screen and transfers the identified image to the remote site. Finally, we show the efficiency of the implemented system through the simulation of the controlled situations, such as tracking coverage on objects, object expansion, object detection number, monitoring the remote transferred image, number of frame per second by the image output signal etc..
Efficient Signal Filling Method Using Watershed Algorithm for MRC-based Image Compression
Park, Sang-Hyo ; Lee, Si-Woong ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 21~30
DOI : 10.5392/JKCA.2015.15.02.021
Image coding based on mixed raster content model generates don't care regions (DCR) in foreground and background layers, and its overall coding performance is greatly affected by region filling methods for DCRs. Most conventional methods for DCR filling fail in utilizing the local signal properties in hole regions and thus the high frequency components in non-DCR regions are reflected into DCR after signal filling. In addition, further high frequency components are induced to the filled signal because of signal discontinuities in the boundary of DCR. To solve this problem, a new DCR filling algorithm using the priority-based adaptive region growing is proposed in this paper. The proposed method uses the watershed algorithm and the flooding priority of each pixel for region filling is determined from the degree of smoothness in the neighborhood area. By growing the filled region into DCR based on the computed priority, the expansion of high-textured area can be minimized which can improve the overall coding performance. Experimental results show that the proposed method outperforms conventional algorithms.
Pattern-based Depth Map Generation for Low-complexity 2D-to-3D Video Conversion
Han, Chan-Hee ; Kang, Hyun-Soo ; Lee, Si-Woong ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 31~39
DOI : 10.5392/JKCA.2015.15.02.031
2D-to-3D video conversion vests 3D effects in a 2D video by generating stereoscopic views using depth cues inherent in the 2D video. This technology would be a good solution to resolve the problem of 3D content shortage during the transition period to the full ripe 3D video era. In this paper, a low-complexity depth generation method for 2D-to-3D video conversion is presented. For temporal consistency in global depth, a pattern-based depth generation method is newly introduced. A low-complexity refinement algorithm for local depth is also provided to improve 3D perception in object regions. Experimental results show that the proposed method outperforms conventional methods in terms of complexity and subjective quality.

IoT is the foundation technology that the things share the information through connected with Internet to provide service based on these information. It is applied to various fields such as personal, public and industry. Therefore, the service development is required to meet the requirement of the various service environments. The IoT service environment will be developed as the participation IoT service environment which increase the value and efficiency such as the Broadcasting and web services changed from the service provider environment to the user participation service. The user can directly reflect their requirements using the user participation IoT service environment. So, the types of IoT services will diverse and accelerate the spread of IoT service. In this paper, we derive the IoT service element through the analysis of various service scenarios, and propose the participation IoT service model and modeling mechanism. It provides the sequential service model and the relation based service model according to the service modeling proficiency of user. The proposed environment provides the web-based user interface that is implemented by the participation IoT service brokering platform.
Development of the Cross-vertical Ontology for Context Aware Service in Various IoT Environment
Yang, Nari ; Choi, Hoan-Suk ; Rhee, Woo-Seop ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 58~73
DOI : 10.5392/JKCA.2015.15.02.058
In the IoT environment, context information is important to provide context service to the user. For this, collected data from devices such as sensors or actuators, converts to context information using the ontology. Because the existing ontologies designed for target service, if the user wants to change the service requirements, service condition, service environment or another service, overall ontology will be redesigned to the changed service. To overcome this difficulty, we propose the cross-vertical ontology model called the Generic Ontology Models(GOMs). It can define the user's desired services without regarding to place and situation. Also, we propose IoT service concept model that represents data flow of the IoT service and IoT service environment. Moreover, as the use case, we show that the proposed GOMs are able to provide the IoT service well.
Development of Content for the Robot that Relieves Depression in the Elderly Using Music Therapy
Jung, Yu-Hwa ; Jeong, Seong-Won ;

DOI : 10.5392/JKCA.2015.15.02.074
The positive effect of percussion instruments can induce increases in self-esteem and decreases in depression in the elderly. Based on this, the content for a percussion instrument robot that the elderly can use to play music is developed. The elements of the interaction between the elderly and the robot through the robot content are extracted. Music that arouses positive memories in the elderly is selected as part of the music therapy robot content in order to relieve depression, and a scoring system for playing music is constructed. In addition, the interaction components of the robot's facial expressions, which stimulate emotions and sensitivity in the elderly, are also designed. These components enable the elderly to take an active part in using the instrument to change the robot's facial expressions, which have three degrees of emotion: neutral-happy, happy, and very happy. The robot is not only a music game machine: it also maximizes the relief of depression in the elderly through interactions with the robot that allow the elderly person to listen to what the robot plays and through the elderly person becoming involved and playing music along with the robot.

Through advances driven by the Internet and the Smart Revolution, the amount and types of data generated by users have increased and diversified respectively. There is now a new concept at the center of attention, which is Big Data for assessing enormous amount of data and enjoying new values therefrom. In particular, efforts are required to analyze narratives within video clips and to study how to visualize such narratives in order to search contents stored in the Big Data. As part of the research efforts, this paper analyzes dialogues exchanged among characters and offers an interface named "Character-net" developed for modelling narratives. The interface Character-net can extract characters by analyzing narrative videos and also model the relationships between characters, both in the automatic manner. This signifies a possibility of a tool that can visualize a narrative based on an approach different from those used in existing studies. However, its drawbacks have been observed in terms of limited applications and difficulty in grasping a narrative's features at a glace. It was assumed that Character-net could be improved with the introduction of information design. Against the backdrop, the paper first provides a brief explanation of visualization design found in the data information design area and investigates research cases focused on the visualization of narratives present in videos. Next, key ideas of Character-net and its technical differences from existing studies have been introduced, followed by methods suggested for its potential improvements with the help of design-side solutions.
Direction Presentation of Design on Privacy Preserving Mechanism for Location-Sharing Based Services
Kim, Mihui ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 101~108
DOI : 10.5392/JKCA.2015.15.02.101
Location-sharing based service (LSBS) refers to a service that users share their location information with other users with whom friendship. At this time, the location information is shared through service provider, and then their position information is exposed to the service provider. The exposure of this personal position information to the service provider has raised a privacy problem, and thus privacy preserving mechanisms have been proposed to protect them. In this paper, we examine the types and features of the proposed location-sharing based services so far, and survey the research trend of privacy preserving mechanisms for them. Through the analysis on existing privacy preserving mechanisms, we present design factors for a privacy preserving mechanism for the current LSBS services, and suggest future work.

Subject Matter in Lee Chang-Dong's Film
Chae, Heeju ; Min, Kyungwon ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 122~129
DOI : 10.5392/JKCA.2015.15.02.122
Director Lee Chang-dong's movies deal mainly with the matter of subject as a human individual. He attempts to show how the subject as a human individual is structured in society through the characters in the movies. It can be seen that a considerable part of this is connected to the matter of subject which is maintained by Michel Foucault, a modern French philosopher. Foucault contends that the subject has lost its identity in the huge structure of society and has become the object. The subject is alienated within the power. The subject is also divided into normality and abnormality in the social structure. Particularly, the movie
directed by Lee Chang-dong shows an individual containing consideration toward self and Foucault also showed his attempts in his later years to newly interpret the subject in the context of consideration toward self. Through this thesis, I attempt to examine the matter of the subject that the film director Lee Chang-dong and Foucault have in common.
The study of Internal Meaning of Mise-en-Scène in Realism Movie -How Hong Sang-Su Handles His Realism with Ordinary Life-
Jin, Seung-Hyun ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 130~138

Korean movies with a great variety of styles have recently succeeded in drawing people's attention Rule number one is "the more entertainment, the more audiences". On the top of box offices are always the movies that have a number of spectacular scenes, pounding sounds and big budget characters. Hong Sang Su movies, however, receive attention from the public without above noted descriptions. One of his effective methods of expression is "realism" He has illustrated the trivial episodes with his own wits and ways. Not only has his style become famous and popular but he has many followers. He enjoys using ordinary emotion and sentiment that are likely to happen to everyone. This paper uses two tools. One is the traditional analysis of realism. The other is how he can approach the public meaningfully by listing common elements he frequently uses in his movies. Nevertheless, we can't fully understand his realism by explaining how he shows our everyday life and how much his movie looks like it. Though admitting there are so many preceding papers on his works but this paper will try to look deep into his realism through the analysis of Mise-en-Sc

DOI : 10.5392/JKCA.2015.15.02.139
This study highlighted influences which affect purchase intention of audience to viewing performance. And after grouping audience types by applying the cluster analysis to samples which are collected by survey, this study examined how purchase intentions influence audience to viewing performance by each audience type. Thus, to improve the reliability to classify audience type, the sample was selected by considering neither age group nor previous experience of viewing performance arts. Factor analysis and reliability analysis was performed to analyze the effect of purchase intention according to the type of audience. And we used AMOS program to verify using SEM(Structural Equation Modeling) how affect it was with moderating variable of audience type. Through surveying and analyzing th results, we confirmed that viewing motivation and quality of performing work have significant effect on purchase intention and significant moderating effect according to audience type. Therefore, we contribute to make suitable strategy that they figure out audience type, when performing art organizations make marketing strategy.
Success Model Setting for Historical, Cultural Theme Park Development -With an Example of Korean Culture Theme Park-
Kwon, Ki-Chang ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 151~162
DOI : 10.5392/JKCA.2015.15.02.151
A theme park is a complex space, in which held is a performance & exhibition event created to make visitors feel fun and a deep impression through a certain theme. Recently, local governments are increasingly planning for theme parks with the aim of local economy revitalization. Accordingly, this paper set up a development model for a Korean culture theme park after deducting success factors for creating a successful theme park through the case of Korean culture theme park. To be concrete, this paper deducted the success factors through literature research and case research as follows: Setting of themes having identity and consistency; programs that can give fun and a deep impression; convenient support facilities reflecting customers' needs; differentiated marketing for progress in customer attraction power; location linked with cultural resources around a theme park and a space for communicating a message; privately-initiated project promotion and the main body of operation; target setting consequent on market segmentation, and demand forecast, etc. A theme park cannot be successfully operated to contribute to local economy revitalization until such success factors should be closely linked and harmonized with each other. In addition, in order for a theme park to make a continued growth, it's required that problems occurring at the operational stage should be endlessly improved, and contents strengthening should be continuously done in line with circumstances of the times and viewers' eye level.
A Study on Storytelling and Musical Composition of the Sillian Song -Focusing on the 'mojookjirangga'-
Lee, Chang-Ho ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 163~176
DOI : 10.5392/JKCA.2015.15.02.163
This study aims to decode newly 'Mojookjirangga' of the Sillian songs on higher viewpoint that is to integrate previous decodings; furthermore to discuss a musical composition of the Sillian song. So to speak, when we read 'hoe(廻)' as 'gam(감)-' instead of 'dol(돌)-' in the song 'Mojookjirangga' which was written in Chinese Characters, such a decoding contributes largely to grip the deep meaning-structure of the elegiac song. Consequently we are able to sing that 'Mojookjirangga' according to the characteristics of national music. However the characteristics of national music are 1) the length of a phrase makes a rhythm, 2) the first beat is strong beat and becomes more and more weak, 3) there are shaking sounds on the long rhythm and changing vowels, 4) there is deep and great dignity in those national music songs. Then we can find those characteristics easily at Sijo-songs. In fact, the Sillian songs and Sijo-songs of Chosun period are more popular music. Then we are going to sing 'Mojookjirangga', referring to the method of Sijo-song and the characteristics of national music. Nowadays such an attempt is to contribute to enrich our national culture and to make the global Korean-stream more abundant.

This paper purposes to identify who is/are in charge of KBS broadcasting programming in view of freedom of broadcasting and interest of audience under the circumstance that Blue House put pressure on KBS to refrain from reporting Sewol Ferry disaster. For this purpose this study has reviewed prior theses, books, journals, laws, and cases, etc. It is analyzed that principal agents in charge of freedom of broadcasting journalism and programming are KBS employees in charge of producing broadcasting programs and KBS chief programming officer, who is appointed by KBS CEO. KBS CEO, who can easily be influenced by governmental pressure in terms of KBS structure, should avoid interfering with programming and producing directly or indirectly for freedom of the press and public interests.
Media-Content Repertoire Development and Difference Analysis: Focus on the Entertainment Content
Lee, Minjoo ; Ryu, Sunghan ; Kim, Young-Gul ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 196~207
DOI : 10.5392/JKCA.2015.15.02.196
This study introduced the concept of 'Media-content repertoire', which indicates the set of favorite media-content combinations of media users and extracted five media user types based on those combinations. We used the range of media(i.e., smartphone, tablet, PC, and TV) and entertainment content(i.e., movie, broadcasting, music, and game) for the analysis. Also, we investigated the differences between those types including demographic variables, individual characteristics, and content buying behavior and we found that statistically significant differences exist among them. Those include 'non-user'(i.e., lower level of media use), 'screen user'(i.e., 50s, TV-centered media use), 'variety seeker'(i.e., 20s. heavy public transport user), 'selective focus'(i.e., 20,30s, movie&broadcasting-centered media use), and 'heavy user'(i.e., high level of media use and consumption). The results provide both academic implications(e.g., extension of media repertoire concept) and practical implications(e.g., direction to the target marketing for each user type).

DOI : 10.5392/JKCA.2015.15.02.223
This research aims to suggest ways to improve the effectiveness of disciplinary suspensions of police officers. Research is based on reviews of prior research and related documents, in addition to analysis of the current status of disciplinary action through public information provided by the National Police Agency. The researcher examined cases in appeal commission example book and analyzed the types and reasons for such cases. This study offers three proposals for improving the disciplinary system. First, the discipline guidelines of police officers should be examined in relation to those of other government employees. Second, a comprehensive manual for data from the disciplinary process should be created and used institutionally. Lastly, police officers should establish an appeals commission that already exists within various civil service operations.

DOI : 10.5392/JKCA.2015.15.02.233
In this study, I examine whether differences in the levels of job satisfaction and turnover intention exist with regard to the police department size. To accomplish this, a way ANOVA analysis of variance(One-way ANOVA) was conducted. As a result, a significant differences were found in job satisfaction and turnover intention according to the department size and grade. Specifically, first, in the job satisfaction level on the department size, the smaller department size was, the lower job satisfaction level was and the bigger department size was, the higher job satisfaction level was. Second, in the turnover intention level on the department size, the result was not statistically significant. Third, in the job satisfaction level on the department grade, the lower department grade was, the higher job satisfaction level was and the higher department grade was, the lower job satisfaction level was. Fourth, in the turnover intention level on the department grade, the lower department grade was, the lower turnover intention level was and the higher department grade was, the higher turnover intention level was.
A Plain Language Policy Institutionalized in the U.S. and Implications for Korea
Kim, MyungHee ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 242~251
DOI : 10.5392/JKCA.2015.15.02.242
This paper is to analyse statutes and execution system on 'plain language policy' of the U.S. in the process of policy was instituted, and to suggest the meaningful implications for Korean easy public language improvement project based on the conclusions drawn. The summarized conclusion is as follows. First, the continuous interests of Presidents and taking the lead of federal agencies played important roles until the U.S. plain language policy has been established as a system. Second, in executing the U.S. plain language policy, laws legislated by period contributed to elicit mandatory compliances from the federal agencies. Third, a propelling agent of plain language policy, PLAIN, is not an administrative department but a community consisted of federal employees and experts. Fourth, plain language policy was unexpectedly given wholehearted support and assistance by Presidents and their administrations from the reform-minded Democratic party. Fifth, during the 2000s most federal departments and agencies held self-managed websites and programs related to plain language. To conclude the current U.S. plain language policy surely performs a mechanism to improve communication and a role as a ladder of trust between the public and government.

Kim, Nami ;
The Journal of the Korea Contents Association, volume 15, issue 2, 2015, Pages 252~261
DOI : 10.5392/JKCA.2015.15.02.252
The aim of this study is to gain a better understanding of the relationship between the mental health and spiritual wellbeing of the wives of pastors by analyzing the influence of both negative and positive elements of mental health (depression and psychological wellbeing) and spiritual wellness. The findings of conducted survey and the analysis of its result on the 236 subjects to measure their psychological wellbeing, depression, and spiritual wellbeing are as follows: First, the verified result of the differences between depression, psychological wellness, and spiritual wellness depending on the demographic variables revealed that the satisfaction level of ministry uniquely showed a 5% level of significance. Second, depression showed a negative correlation with spiritual wellbeing, and a positive correlation with psychological wellbeing, which proves that rather than depression, psychological wellbeing possesses a greater influence on spiritual wellness. Third, a one-level increase of depression and psychological wellbeing had an influence on spiritual wellbeing by - 0.282 and 0.668 respectively. Lastly, the study categorized the subjects into two groups -- those who are satisfied with their ministry and those who are not -- to analyze the influence of the sub-factors of depression and psychological wellbeing on the sub-factors of spiritual wellness. As a result, both groups showed that depression had significant influence only on the existential wellbeing, while psychological wellbeing had an influence on both religious and existential wellbeing, and rather than depression, a negative state of mental health, a psychological wellbeing which is a positive state of mental health had a greater influence. The study also revealed that depression and psychological wellbeing had a greater influence on the group that is dissatisfied with their ministry than the group that is satisfied.

The number of stepfamilies is rapidly growing in our society according to social changes. So family programs especially for stepfamily relationship enforcement with adolescents at home are needed. The purpose of this study is to investigate the direction of family programs for enforcing the stepfamily relationship between stepparents and stepchildren. For the purpose, case studies from those stepfamilies were analyzed through qualitative interviews and early developed program contens were referred. Based on discussion mentioned above, program development direction for stepfamily relationship enforcement is not only dealing with difficulties of stepfamilies in their early remarriage but also emphasizing their advantages. In conclusion, this program development direction expected stepfamilies to resolve their problems and to prevent their family break up as well as to deliver practical benefits.

DOI : 10.5392/JKCA.2015.15.02.281
This study investigated the relationships between factors of aggression and satisfaction with life and the differences of irrational belief, primary secondary anger thought, and satisfaction with life among four groups classified based on the levels of hostility and verbal aggression. 268 middle school boys in Chungnam areas served as subjects. The results showed that hostility showed the most negative correlation with satisfaction with life. Stepwise regression analyses showed that hostility negatively predicted satisfaction with life, whereas verbal aggression positively predicted satisfaction with life. Factors of irrational belief, primary/secondary anger thought were negatively correlated with satisfaction with life. Analyses of variances revealed that covert hostility group showed higher scores on self-depreciation, disregard and disappointment in intimate relationship situation, hopelessness, whereas overt hostility group showed higher scores on derogation of others/revenge. In addition, covert hostility group showed lower scores on satisfaction with life than other groups. Finally, limitations of this study and suggestions for future study were discussed.

The purpose of this study was to examine the awareness of dental hygiene students on sexual harrassment in an effort to provide some information on the prevention of sexual harrassment. The subjects in this study were 738 dental hygiene students at colleges located in four different large regions. As for the concept of sexual harrassment, the students got 4.33 out of a possible five in that regard, which was a high score. But they got a relatively lower score of 3.42 in awareness of the causes of sexual harrassment. They got the highest score of 4.42 in physical sexual harrassment among different types of sexual harrassment. Regarding the offender of sexual harrassment, they got 2.81 out of a possible five, which was lowest among their scores in the items of sexual harrassment awareness. There were statistically significant differences in sexual harrassment awareness according to gender, age, grade and religion. The above-mentioned findings of the study illustrated that the dental hygiene students were well aware of sexual harrassment in general, but that the way they coped with it was quite passive. The development of educational programs on how to prevent sexual harrassment and cope with it is required to spread better awareness of sexual harrassment among college students and to encourage them to properly cope with it.

Chronic pain is one of the leading causes of hospital visits. It not only affects the patients themselves but also has a major negative impact on their families and society. In this study, we investigated epidemiology of musculoskeletal disorders induced chronic pain among general population based on Korea National Health and Nutrition Examination Survey database and also analysed how it influenced on the use of medical services. This study was done by using the data of 5th Korea National Health and Nutrition Examination Survey (KNHANES V), taking aged 20 years and over adults as research subjects. The EuroQoL-5 Dimension Index(EQ-5D) was used as a survey instrument. T-test, chi-square test and multivariate logistic regression were used for statistical analysis. Subjects with chronic pain had a higher likelihood than control group to use medical services(odds ratio : 5.858, confidence interval 3.636-9.438). Controlling for existence of chronic pain, more women were likely to use medical services than men(1.156, 0.707-1.889). Age, gender and household income level did not affect the use of medical services. Proper control of chronic pain is very helpful in improving patient's quality of life and it also accounts for a large proportion in suppressing excessive consumption of medical services. Anesthesia and pain medicine specialists have superior knowledge about analgesics and anticonvulsants than other physicians do and also have specialized skills to perform procedures like nerve blocks in treating chronic pain. Therefore Anesthesia and pain medicine specialists need to play a leading role in managing chronic pain.

The friction velocity is a quantity with the dimensions of velocity defined by the friction stress and density of a wall surface at near wall of flow condition. Also, the friction velocity is the hydraulic parameter describing shear force at the bottom flow. Moreover, it is a very important factor in designing open channel and essential to determine the mixing coefficient in the main flow direction. The estimation of the friction velocity are such as methods using channel slope, linear law of the mean velocity at viscous sub-layer and direct measurement of wall shear stress, etc. In the present study, we propose a friction velocity equation that has been optimized by combining the concept of entropy, which is used in stochastic method, and to verify the proposed equation, the experimental data measured by Song was used. The R squared for friction velocities between proposed equation and friction velocity formula analyzed 0.999 to 1.000 in a very good agreement with each equation.

Along with the rapid diffusion of smart devices, smart learning has been taking place as a main pedagogy in education. Under these drastic changing circumstances, social presence and interaction between learners have been highlighted as key factors in educational research. In this light of rising importance, this study examined the effects of modality and smart device on users' perceived social presence and interaction experience in a smart learning environment. It conducted 2(text based interface vs. audio/video based interface) by 2(smartphone vs. tablet PC) between-subjects experiment. 80 participants were systematically recruited and randomly assigned to four conditions. The findings showed that social presence was higher in audio/video based interface condition than in text based interface condition. Modality also had a positive effect on learner's interaction experience. On the other hand, the effect of smart device is found to be statistically insignificant. Instead, interaction effect existed between modality and device on social presence. The result of this study suggests that the modality and characteristics of device should be considered seriously when designing interface of smart learning contents. The findings in this study provide future studies with heuristic implications by highlighting users' perceived cognition and experience.

The purpose of this study is to examine how Korean college students perceive and produce American English vowels /i, ɪ, eɪ,
, ɔ, oʊ, ʊ, u, ʌ/ embedded in CVC words, and further to examine the relationship between perception and production of the target vowels. Forty-two participants who are English major/double major were divided into 2 groups under different conditions: the control group took only theoretical lessons about English phonetics and the experimental group took 4-week phonetic training lessons in addition to the theoretical ones. The result of the pretest revealed that the two groups showed strong correlations between perception and production. However in the post-test, both of the two groups had no correlation between the two elements. The two groups showed changes in the correct percentage in the post-test and this had the influence on the correlations between perception and production. The control group showed the fluctuation in perception, whereas the experimental group showed improvement in production, and these changes in the post-test had an influence on the correlations between perception and production. Based on this analysis, pedagogical implications were discussed and limitations of the study were also described.

This paper deals with suicide that has become a serious problem in our society as well as in the world today from a Christian perspective. Historical position regarding suicide is divided into two; some see it as a brave and honorable act and give approval to it, the others view it as act of giving up the life that is given by God and are opposed to it. Though suicides in the Bible are mostly committed to maintain honor, because of Augustin's position it became negative in Christianity, leading to a thought that one who committed suicide goes to hell. Why then people commit suicide? The views of scholars on the cause of suicide are divided into three; biological, psychological, sociological. My position is that though each or all of them contribute to suicide, yet the decisive factor is on how a person reacts to them. Major factor of suicide is how humans as interpretive beings accept the present despair. On the basis of this understanding of suicide and humans, I conclude this paper with three new recognitions as an essential answer to suicide. First, humans are made in God's image and belong to Him, thus their life is precious. Second, Christianity views humans as ones look for the hope in the future as the eternal life. Third, suicide is a violation of the commandment 'do not kill' yet it is not an act of sin but a disease that needs to be cured. To achieve this Christianity must not only spread the idea of respect for life and also run suicide prevention center every city.
