Moral Disengagement in Information Security Context: A Study of Antecedents and Outcomes
Yim, Myung-Seong ;
Journal of Digital Convergence, volume 11, issue 11, 2013, Pages 1~13
DOI : 10.14400/JDPM.2013.11.11.1
Every big online security breach seems to end in a big lecture. Thus, although a predominant weakness in properly securing information assets is the individual user within an organization, much of the focus of extant security research is on technical issues. The purpose of this study is to explain why insiders breach security policy by applying the moral disengagement theory. There are no consistent, widely accepted theories or theoretical frameworks in the literatures as to why insiders breach of information security, and therefore no clear, effective guidance on what to do to prevent employees from violating information security policy in organization. To do this, we theorize that moral disengagement may play a mediating role connecting stable individual differences to intention to breach security policy, because of some of the individual differences. We found that policy awareness and perceived punishment have a negatively significant effect on moral disengagement. However, negative affectivity has a positively significant influence on moral disengagement. Furthermore, moral disengagement has a positive effect on intention to breach security policy. Conclusions and implications are discussed.

The purpose of this study is to develop the evaluation system of which the city safety can be realized in the U-City. The evaluation system on "how much safe the present city is" and "how much safe it will be in the future" has been selected and the criticality has also been analyzed. The result of criticality analysis is that the indicator for "how safe the current city is" showed that the disaster prevention and environmental field are important. In the future, the indicator of possibility for the U-safe city should be prepared by the imtegrative operation management system, and on the basis of this, it also showed that the necessary indicator to build the system for keeping the safe city is important. The evaluation system for the U-safe city, hereafter, can be utilized for the city plan, construction, operation, and management utilized by IT in local government.

To accommodate the rapid growth of e-commerce transactions, non-face-to-face transactions, businesses use a wide variety of payment methods. However, many of these payment mediums are not secure as shown by increases in fraudulent transactions. In this paper, we analyze a particular e-commerce transaction medium, the Safety Transaction Service (STS). This system protects consumers through a wide variety of safeguards: safety settlement systems (escrow), consumer damage compensation insurance, payment guarantee, and secure bank settlement. In contrast to the safeguards, we identify the limitations and concerns with the STS and potential legal and political improvements. The plethora of payment methods limits the consumers ability to distinguish between the secured and unsecured transaction services. Regulation and consumer based verification of transaction services are essential to root out dangerously fraudulent systems. We propose the development of specific standards to these systems, in particular the need for consumer confirmation and clear settlement documentation. Only through the active promotion of scrutiny and improvement to STS will consumers be protected in e-commerce.

Prior to full-scale implementation of smart grid, the Korean government is conducting a smart grid testbed in Jeju island. However, the participants of the ongoing program are skeptical about the success of the expansion of smart grid. The concern rises from various reasons; the limits of the Korean electricity market mainly led by both the government and KEPCO, high stability and reliability of the existing electricity grid, insufficient utilization of renewable energy, and public fear of raised electricity bills. Five key issues in regards to facilitating the Korean smart grid market are extracted and evaluated. The issues are conflict of interest among participants, the effect of introducing real-time pricing, lack of customer participation of demand response, and absence of business models.

Due to the wide spread of the perception of cloud computing, the usage of cloud computing is increasing globally. Cloud computing is able to converge the various industrial domains based on ICT and it is more and more popular because it has a lot of benefits such as cost savings etc. in global economic recession. However, if cloud computing service is to achieve its potential, it is necessary to clearly understand the critical issues such as service security, performance and availability and so on from the perspectives of the providers and the consumers of the cloud service. In addition, customers focus on how to get and use the safe and reliable cloud service. In order to meet these problems, Korea cloud service certification system and Japanese ASP-SaaS-Cloud certification system were performed in each country. This paper aims at comparing and analyzing between them and describing the difference. Eventually, we propose the improvement strategy of Korea cloud service certification system based on the comparison results between them.

As people invest most of their asset in real estate, there is high interest in changing in housing and real estate prices in the future for a digital economy. Various variables are affecting the housing and real estate market. Among them, four variables : households, productive population, interest rate and index price are chosen and analyzed representatively. This study is aimed to build decision model of apartment prices in Seoul empirically. From the analysis result the stock index is the only variable which is significant statistically to apartments in Seoul. From this study, the households and productive population show the same direction as shown in the previous studies before but not significant statistically. Among the independent variables, the stock index is chosen as a major variable of determinant of Seoul apartment price. From the result of the research, prediction of stock market should be preceded to forecast the movement of housing and real estate market in the future.

In a EFL situation, most Korean students and teachers are exclusively dependent on English textbooks to acquire the cultural factors of English. Therefore, it is necessary to analyze cultural elements in the English Textbooks. The results of the study are as follows: First, although all of the textbooks contain the culture part at the end of each lesson, it is insufficient for students to build a cultural schema. Second, in the analysis of cultural types, three types of cultures are presented in a similar percentage. Third, the culture elements were analyzed based on the 7th national curriculum revised in 2011. The most dominant is the culture regarding arts and literature. Forth, in nationality analysis, universal culture takes up the largest portion. Therefore, it is required more efforts to improve students` knowledge of the American and English culture.

DOI : 10.14400/JDPM.2013.11.11.85
This paper presents a novel mobile measurement system with multi antennas which enable mobile measurement as well as fixed measurement with telescope mast. Proposed system installed 4 omni directional antennas for the space diversity process and one directional log periodic antenna for the simultaneous conventional fixed measurement. Whole antenna systems are connected to the custom DTV channel analyzers with Ethernet networks respectively and processed by the main controller to calculate real time average receive levels. To prove the performance of proposed system, the typical receive models are categorized as 3 area types - open area, building area and house area, and then intensive field tests were performed through mobile and fixed measurement phases. With these measurement data, the relationships between mobile and fixed measurement are analyzed, and the concept of compensation factor is proposed to assume the average receive level of signal. The field test is fulfilled as a co-work with public broadcasters and the proposed system is applied to the intensive coverage measurement projects for metropolitan areas by the korean government agencies.

Recently, our society is seeing cultural value in a new light, perceiving it as an element that creates new values added. Reflecting this trend, the local governments in various levels focus on reviving the regional economies by enhancing cultural competencies and developing the culture and tourism industries. This research is conducted to perform the policy project `administrative support plans to make Seongnam a hub of international culture and tourism,` which was proposed as part of the urban renewal strategy of the city. This study proposes the establishment of `policy communities` to build the infrastructure for `creative cultural content tourism` as a plan to accomplish the policy goal pursued by Seongnam. The focuses include what the policy communities are, how they work, and what the local government has to do with them for a successful implementation of proposed policies, by theoretically examining the composition variables of policy communities. In particular, the study concentrates on how to reconstruct the infrastructure for the culture content technology (CT) in the IT-based city and to transform itself into a city of "creative cultural content tourism". If the policy communities are formed under the proposed model in this paper, it is expected that they will become the viable alternatives in the field.

The proportion of small and medium sized enterprises based on the number of corporations in China is 99%, the number of employees is 80%, and the proportion of GDP is 60%. These facts show that small and medium sized enterprises have an very significant effect on the economic growth of China. However, most of the researches conducted so far have studied large corporations, thus, there are relatively insufficient researches on the determinant of the capital structure of small and medium sized enterprises. Therefore, the purpose of this paper is to confirm the factors that determine the capital structure of small and medium sized enterprises in China. To achieve this purpose, we performed multiple regression method to 45 small and medium sized manufacturing enterprises listed on the Shenzhen Stock Exchange of China. Results of this study are as follows. First, the growth appeared to have a significant positive effect to the debt ratio in 1% significance level. Second, the profitability appeared to have a significant negative effect to debt ratio in 1% significance level. Third, the firm size appeared to have no effect on the debt ratio. Fourth, the secured value and tax shield effect by non-debt appeared to have a weak positive effect on the debt ratio, however these variables showed statistical insignificant.

The campus has been composed of a very variety buildings. However, there is almost no easy way to see information about room number of each floor of the buildings and all buildings. For that reason, in this paper, we have developed a 3D simulation system for the 3D visualization of campus building information. Each building and cross section of floor was modeled in 3D based on the actual drawing. And texture mapping were using real photos. The user interface was divided into frames for menu and 3D viewer. When you select a building name from the menu, 3D viewer shows the selected building by zooming. And menu frame is shown the various information related to the building. Also when you select a room number of each floor, a separate web browser shows the cross section by VRML viewer. Conversely, when you click on the building in the 3D viewer, menu frame is shown the various information related to the building. This system is very useful in that provide realistic building information of campus.

Rough set theory comes to derive optimal rules through the effective selection of features from the redundancy of lots of information in data mining using the concept of equivalence relation and approximation space in rough set. The reduction of attributes is one of the most important parts in its applications of rough set. This paper purports to define a information-theoretic measure for determining the most important attribute within the association of attributes using rough entropy. The proposed method generates the effective reduct set and formulates the core of the attribute set through the elimination of the redundant attributes. Subsequently, the control rules are generated with a subset of feature which retain the accuracy of the original features through the reduction.

Naive Bayesian classifiers are a powerful and well-known type of classifiers that can be easily induced from a dataset of sample cases. However, the strong conditional independence assumptions can sometimes lead to weak classification performance. Normally, naive Bayesian classifiers use Gaussian distributions to handle continuous attributes and to represent the likelihood of the features conditioned on the classes. The probability density of attributes, however, is not always well fitted by a Gaussian distribution. Another eminent type of classifier is the neuro-fuzzy classifier, which can learn fuzzy rules and fuzzy sets using supervised learning. Since there are specific structural similarities between a neuro-fuzzy classifier and a naive Bayesian classifier, the purpose of this study is to apply learning distribution graphs constructed by a neuro-fuzzy network to naive Bayesian classifiers. We compare the Gaussian distribution graphs with the fuzzy distribution graphs for the naive Bayesian classifier. We applied these two types of distribution graphs to classify leukemia and colon DNA microarray data sets. The results demonstrate that a naive Bayesian classifier with fuzzy distribution graphs is more reliable than that with Gaussian distribution graphs.

Ant Colony System(ACS) is a meta heuristic approach based on biology in order to solve combinatorial optimization problem. It is based on the tracing action of real ants which accumulate pheromone on the passed path and uses as communication medium. In order to search the optimal path, ACS requires to explore various edges. In existing ACS, the local updating rule assigns the same pheromone to visited edge. In this paper, our local updating rule gives the pheromone according to the total frequency of visits of the currently selected node in the previous iteration. I used the ACS algoritm using subpath for search. Our approach can have less local optima than existing ACS and find better solution by taking advantage of more informations during searching.

This study was to determine the effect of 12-week balance training with visual feedback on balance and walking functions in patients with post-stroke hemiparesis. Twenty individuals with chronic stroke volunteered to participate in this study. They were randomly allocated to either experimental group (EG) or control group (CG), with 10 subjects in each group. Subjects from the group 1 underwent 15-min balance training with visual feedback and 15-min routine-scheduled physical therapy, and subjects from the group 2 performed 30-min routine-scheduled physical therapy only, which comprised mat exercise, strengthening, postural correction, and functional practice. Assessment tools were made with the Functional Reach Test (FRT), Timed Up and Go Test (TUGT), and 6 Min Walk Test (6MWT). In within-group comparison, the EG showed significant differences in all parameters (p<0.05), while significant differences were not found for the CG (p>0.05). In between-group comparison, the change values of the FRT and 6MWT appeared to be significantly greater for the EG than those of the CG (p<0.05). These findings suggest that balance training with visual feedback may be favorably used to improve balance and walking functions in patients with chronic post-stroke hemiparesis. Further studies with larger sample and long-term follow-up period need to generalize the results of this study.

This study aimed to compare the effects of microcurrent stimulation and rest on the fatigue index by applying both to subjects who had accumulated fatigue after performing short-duration physical activity. The experiment was performed at S University from December 2012 to February 2013, on 22 healthy men in their 20s, who were right-handed, and without peripheral or musculoskeletal diseases. All subjects lifted a 10-kg box lift and lower 100 times in 15 minutes. Immediately after that, muscle fatigue index (Median Frequency: MF) and blood fatigue index (Creatine Kinase Lactate: CK, Lactate Dehydrogenase: LDH) were measured by using surface electromyography. The subjects were divided into two groups, and microcurrent stimulation and rest were mediated to the experimental and control groups, respectively, for 20 minutes. After intervention, muscle fatigue index and blood fatigue index were measured and the changes in the accumulated fatigue index were compared. Both groups manifested significantly decreased cumulative fatigue after applying the mediation compared to the pre-intervention level (p < .05), the only exception being the fatigue index of the left erector spinae in the rest group. Compared to the rest group, the microcurrent stimulation group showed a significant decrease in muscle fatigue index (p < .05) but no significant differences were found in the blood fatigue index. Given the results of this study, microcurrent stimulation is considered to be helpful in muscle fatigue recovery for workers who have to perform repetitive movements lifting weights, and additional studies on the correlations of the fatigue recovery with respect to the long-term follow-up of fatigue index and mediation time are necessary.

DOI : 10.14400/JDPM.2013.11.11.573
Targeting in-dorm university students, this study is to check body-shape perception, obesity, weight control, and obesity stress, and to figure out the effect level of each variables toward obesity stress. Data were collected by self-evaluation questionnaire from 305 respondents in dorms of a university, and the survey was conducted from May 27 to June 7 of the year 2013. As a result of the survey, both male and female students did not properly perceive their own body-shape. Female students felt that they were fat more than male students did; on the other hand, male students felt that they were skinny even though they were in standard. Females felt more obesity stress than males, and for both male and female students, more obesity resulted in deeper obesity stress. For female students, when the actual body shape is not similar to the body shape that they believe to be, they feel more obesity stress; however for male students, the result was reversed. The group that tried weight control felt more obesity stress than the other group, for both males and females. In addition, for both male and female, the group that has more will toward weight control felt more obesity stress. The effect factors that were checked through multi-variable analysis is like the following: for male students, as they feel fat and as they pay more attention to weight control, the obesity stress increased, and for female students, as they pay more attention to weight control, the obesity stress increased. Focusing on higher obesity stress groups that are distinguished through applying factors to influence on decreasing obesity stress based on the analysis result, and especially for male university students, running exercise programs at the same time for skinny bodies to gain fat would be more effective to decrease obesity stress.

Park, Hye-Young ;
Journal of Digital Convergence, volume 11, issue 11, 2013, Pages 603~611
DOI : 10.14400/JDPM.2013.11.11.603
This study examines the impact of job stress on customer-oriented boundary-spanning behavior with the mediating effects of organizational commitment. The survey data was collected from 147 employees working at a hospital and analyzed statistically by using SPSS 18.0 and AMOS 18.0. The result of this study are as follows. Hypothesis 1, Job stress has a negative influence on organizational commitment. Hypothesis 2, Organizational commitment has a positive influence on customer-oriented boundary-spanning behavior. Hypothesis 3, Job stress has a negatively significant impact on customer-oriented boundary-spanning behavior. Accordingly, Organizational commitment has the role of partially mediating the effect between job stress and customer-oriented boundary-spanning behavior. This means that employees working at the point of meeting customers must reduce their job stress in order to improve the service quality of a hospital and creating solutions to reduce job stress of hospital employees can increase customer-oriented boundary-spanning behavior.

This study was conducted to measure and analyze the changes in paraspinal muscles of acute and chronic low back pain patients using MRI, and to provide clinical basic data for diagnosis and treatment for low back pain. For this purpose, 20 patients with acute low back pain frome August 2012 to January 2013 which occurred within 12 weeks, and 20 patients with chronic low back pain that progressed over 12 weeks, were chosen as subjects, and their MRI measurements were compared with one another. As a result, in relation to in the fatty degeneration ratio of the left spine and right spine, there were significant differences in erector spinae and multifidus(p<.001), and in relation to the Fat Infiltration ratio between all the groups, there were significant differences in psoas major, erector spinae and multifidus between the acute low back pain patient group and the chronic low back pain patient group(p<.001). In the post-hoc test, multifidus and erector spinae in the acute low back pain group and chronic low back pain group showed the highest Fat Infiltration ratio. The serious Fat Infiltration of multifidus and erector spinae in the chronic low back pain group led to weakened strength of muscles that stabilize the spine. In conclusion, it is considered that this study would present important data and basis in making acute and chronic low back pain patients pay more attention to multifidus and psoas major during rehabilitation exercise, and selecting a rehabilitation exercise program.

The Baekjae Culture Festival was first held with the objective to re-explore and succeed the traditions of Baekjae culture based on history of Baekjae`s seat of government, Gongju and Buyeo. It has contributed to the development of regional culture and establishment of cultural identity of local community with its pride as the leading historical cultural festival that introduces the history and culture of Baekje. However, the current Baekje Culture Festival as a historical and cultural festival is faced with a criticism as it is operated in the direction far from its initial purpose due to the lack of recognition in its significance and application. Therefore, the National Baekje Cultural Products Concours is held as part of various contests of Baekje Culture Festival in order to encourage the pride of Baekje history, draw international attention for the advanced and unique Baekje culture, develop innovative ideas for cultural products and grow the talents in design. The awarded work of this national concours is believed to be effective for the cultural contents industry. However, unlike its initial purpose, the concours has become a one-time exhibitionist event. Hence, through the analysis of general facts and case of domestic cultural products this thesis aims to find a way to utilize the National Baekje Cultural Products Concours in order to re-evaluate the history and culture of Baekje and enhance the public recognition through their viewing, consuming, promoting and experiencing of cultural products.

Even though civilization is developing at a fast rate, human beings and their living environments do not look happy. Given that the civilization comes from the human mind, which is changing in interaction with human body, society, and nature, it is hard to think that the human mind is changing in the desirable direction. This paper described a whole changing paradigm of the human mind and its causes through the cognitive mechanism in the brain from which all the diverse minds are formed. According to the cognitive mechanism, the human mind can change from the first free and peaceful mind through the middle mind to the last obsessive and anguish mind in accordance with the change of one of the factors in the origin of the human mind. Today`s unfavorable changes in human beings, society, and the natural environment including the excessive development of civilization are the results of the undesirable changes of the human mind. This paper specified the respective characteristics of the first, middle, and the last mind and discussed where individuals` minds are and where they are going. Lastly, this paper suggested the specific ways to return to the first original mind based on the cognitive mechanism.

The electricity demand and supply could be off balance if several electric vehicles(EVs) were charged at the same time or at peak load times. Therefore, smart grids are necessary to flatten the EVs` electricity demand and to enable EVs to be used as distributed storage devices as electricity demand from EV-charging increases. There are still few quantitative studies on the impact of smart grids on managing EVs` electrical loads. In this study, we analyzed the quantitative impact of smart grids on managing EVs` electrical loads and suggested policy implications. As a result, it is identified that smart grids can manage effectively EVs` impact on electrical grids. The electricity market structure and regulatory framework should support the demonstration and commercialization of smart grid technologies.

Neo-liberalism after IMF bailout made the Korean book market flushing with rose due to the alleged self-development books. Vision of self-development books under neoliberal social system is inevitably reduced to a means of capital pursuing commercialization in line with improving the competitiveness of privates through the development of human resources. Characteristics of self-development books, which attributes personal fail to personal responsibility and lack of essential element compared to others in a competitive society, trap individuals forced to choose into anxiety and helplessness. Self-development and healing is a complementary relationship. Human beings needs healing -healing humanities- in the process of self-development. Therefore, humanities should trigger developing and perceiving his own `reflexive life skills`. Individual`s sense of happiness in life and his own experience is very important, and the conscious relationship about their own feelings could elicit `self-reinforcement`.

As the life which existed only offline has changed into a life part of which is led online, it is an important problem to identify whether an online user is legitimate one or not. Biometric authentication technology was developed to identify the user more correctly either online or in offline daily life. Biometric authentication is a technology where a person is identified by his or her unique characteristics, and is highlighted as a next-generation authentication technology replacing password. There are various kinds of traits unique to each individual, and biometric authentication technologies drawing on such traits use various devices and algorithms. Firstly, this paper classified such various biometric authentication technologies, and analyzed the effects of them when they are applied on smartphone, smartwatch and M2M of the different devices platforms. Secondly, it suggested the effectiveness-based AIB(Authentication for Integrated Biometrics) authentication technique, a comprehensive authentication technique, which can be used in different devices platforms. We have successfully included the establishment scheme of the effectiveness authentication using biometrics.
