Internet ethics is one of liberal arts courses in a college. We also have taught this subject for a number of years. In order to effectively communicate to students the internet ethics course, we gave some demonstration practice lectures by taking advantage of internet ethics related videos. Since the latest video presentation and its discussion were performed, it was helpful for students to recognize the internet ethical issues and concerns. However, simply video watching is short in the view of students` learning outcome improvement, since each student just watches the content passively in a class. Thus, we assign small student group consisting of 3 people make a video on internet ethics topic. This team project based class methodology is effective to each student who actively participates in the class and understands the concept which they directly make a video. We confirmed that classroom students` understanding for internet ethics has been increased by a survey of the class attendees.

Stress is one of the major causes threatening the mental and physical health of human today. In this paper, we analyzed the heart rate variability(HRV), galvanic skin response(GSR), and skin temperature data measured from the university subjects before and after the class to examine the influence on bio-signal in stress environment. Thirty subjects from university students (aged between 21 and 27 years; mean

With the aim of developing a smartphone-based point-of-care device that is small, inexpensive, and easy to handle by non-expert, we designed a fluorescence smartscope for counting particles and a DC motor-controlled particle positioning system. Our smartscope can count the number of fluorescent particles and fluorescently-stained white blood cells through a phone camera with an adaptor containing a LED, a ball lens and optical filters and an application running on a smartphone. The motor was controlled wirelessly via Bluetooth with an Android smartphone. We found that axial spinning of a helical microfluidic channel allows arrangement of particles having size similar to the white blood cells. The motor-controlled particle positioning system can minimize time-consuming manual processes and automate sample preparation process and thus, if integrated with the smartscope, it can be used for a point-of-care testing device based on a smartphone.

Steganography is the technique of hiding the existence of a secret message that is communicated hiddenly. Generally, the main objectives of this paper is to develop newer and more sophisticated steganographic techniques based on perceptual transparency, robustness and capacity of the hidden data. This paper analyzes the advantages and disadvantages of image steganography techniques and proposes an effective method. As a result, the images steganography technique based on good ELSB and DCT which applies the rearranged key is secure and effective.

To develop the contents making profit, we propose the program operation methods that can apply the needs of students and the demand of the times, and consider the capacity of the operating agency overall. First, we suggest the distance training motivation, the effective content type, appropriate interaction ratio, the effective teaching and learning methods and the assessment methods. Second, we suggest the development strategy of educational contents, assess quantitative the demand of students and the will of teacher overall, measure the potential success. Third by applying the strategies in the educational field, we product the 12 major development field. These fields are divided into categories A and B, category A is the very high success field and category B is the high potential success field. By applying the proposed strategy, You will select the most suitable contents here and now.
Efficiency Validation for the OVM-based Variability Tracing Method
Lee, Jihyun ; Hwang, Sunmyung ;
Journal of the Korea Industrial Information Systems Research, volume 20, issue 3, 2015, Pages 51~60
DOI : 10.9723/jksiis.2015.20.3.051
Traceability targets provision of information to stakeholders required for analyzing impacts among artifacts due to changes. Unlike single product development, in software product line developing the family of products the complexity of maintaining and managing traceability between two life cycles, domain and application engineering is so high. Accordingly, variability traceability management approach centred on orthogonal variability model that manages variability separated from development artifacts has been conceptually proposed, but its efficiency has not verified yet. This paper verifies whether orthogonal variability model based traceability can provide required traceability through an example. As the results, the OVM-based variability tracing method supports well to narrow down artifacts affected by the changes. However, the method does not support tracing the exact artifacts or exact part of an artifact affected by the change.

This study presents a probabilistic knowledge discovery method to interpret heart rate variability (HRV) based on time and frequency domain indexes, extracted using discrete wavelet transform. The knowledge induction algorithm was composed of two phases: rule generation and rule estimation. Firstly, a rule generation converts numerical attributes to intervals using ROC curve analysis and constructs a reduced ruleset by comparing consistency degree between attribute-value pairs with different decision values. Then, we estimated three measures such as rule support, confidence, and coverage to a probabilistic interpretation for each rule. To show the effectiveness of proposed model, we evaluated the statistical discriminant power of five rules (3 for atrial fibrillation, 1 for normal sinus rhythm, and 1 for both atrial fibrillation and normal sinus rhythm) generated using a data (n

In South Korea, few researches have been conducted into the incidence of injury diseases and into their demographic and sociologic characteristics. This research has estimated and analyzed the results of an questionnaire investigation carried out by the Korea medical panel (2008) and the social economic costs. In particular, an estimation has been conducted of social costs for each type of accident, injury and intoxication and of medical use for the injuries. For the future, it is necessary to develop concrete programs customized for age, education level, economic income and to continually implement injury prevention education, with a view to reducing the injury incidence and medical expenses; and also, individuals` participation in and social and national efforts are required for an efficient operation of the health insurance, for the purpose of reducing social and/or economic costs for injuries in South Korea.

DOI : 10.9723/jksiis.2015.20.3.081
We fabricated a 3D knee joint model through the imaging processing. The 3D shape information is different depends on specific conditions when the shape of real knee joint is extracted from CT/MRI sliced images. The two types of joint models were fabricated by using 3D printer in order to analysis of joint movement by slight difference of 3D shape information. The compressive force experiments were performed by using knee joint model. As the results, the compressive forces were changed with respect to the difference of geometry. Consequently, feasibility test should be performed before developing biomimetic bioreactor.

The accidents caused by drivers while driving are considered as the major causes along with other causes such as conditions of roads, weather and cars. In this study, we investigated the driver`s workloads under three different driving conditions (Weather, Driving time zone, and Traffic density) through analyzing biological signals obtained from a car driving simulator system. The proposed method is able to detect R waves and R-R interval calculation in the ECG. Heart rate variability (HRV) was investigated for the time domain to determine the changes in driver`s conditions.

DOI : 10.9723/jksiis.2015.20.3.095
In order to understand the issues related to corporate social responsibility (CSR) of small and medium enterprises (SMEs), we need to consider SMEs` unique characteristics, such as their size and business environment, which are different from large companies` ones. This paper examined the influence of consumers` expectancy disconfirmation about SMEs` CSR on their disconfirmation into four subcategories including economic, legal, ethical, and charitable responsibility. According to the study results, the economic and charitable disconfirmation factors had a significant impact on corporate image and purchase intention via the corporate image, whereas the legal and ethical disconfirmation factors had no significant impact on corporate image and purchase intention.
