With the increasing expectation on personalized medicine, it is getting importance to analyze medical information in molecular biology perspective. Gene expression data are one of representative ones to show the microscopic phenomena of biological activities. In gene expression data analysis, one of major concerns is to identify markers which can be used to predict disease occurrence, progression or recurrence in the molecular level. Existing markers candidate identification methods mainly depend on statistical hypothesis test methods. This paper proposes a search method based decision tree induction to identify candidate markers which consist of multiple genes. The propose method discretizes numeric expression level into three categorical values and allows candidate markers' genes to be expressed by their negation as well as categorical values. It is desirable to have some number of genes to be included in markers. Hence the method is devised to try to find candidate markers with restricted number of genes.

This study identified personality types of 433 college students of Busan, Ulsan and some regions of Gyeongsangnam-do and inquired into influences of personality types on their satisfaction with clinical practice. According to the results, students with extroverted and low-neurotic tendencies showed significant results in the subordinate factors of satisfaction with clinical practice. As for factors influencing the extraversion factors personality type, it turned out to have a significant level in satisfied with teach (p<0.001), satisfied with facility and satisfied with clinical practice (p<0.05). On the other hand, as for factors influencing the personality type of neurotic tendencies, it turned out to have a significant level in satisfied with practice content (p<0.05), satisfied with teach (p<0.001), satisfied with interpersonal (p<0.05) and satisfied with clinical practice (p<0.05). Therefore, it will be indispensable to conduct a personality type test during the period of university days, to increase satisfaction with clinical practice of students majoring in Dental hygienics. Moreover, based on the test results, it will be required to develop a variety of programs to strengthen a customized counseling program and improve interpersonal skills.

This study aims at creating a daily life satisfaction improvement plan by using motivation for seeking need for rehabilitation services and self-efficacy in individuals who returned-to-work and reemployed injured workers. The subjects of this study were 2,642 returnees and 3,742 reemployed individuals who participated in the first to fifth year survey of the first cohort of the Panel Survey of Workers' Compensation Insurance. The analysis checked the mediating effect through the multiple regression analysis and bootstrapping. The result indicated the need for rehabilitation services had negative impact on self-efficacy and daily life satisfaction whereas self-efficacy had a positive effect on daily life satisfaction and played a mediating role between the need for rehabilitation services and daily life satisfaction. Based on these results, a need for the advancement of social psychological rehabilitation program and establishing an integrative rehabilitation process were identified.

This study is to investigate the effect of lower extremity strength exercise using biofeedback system on community-based elderly. Ten community-based elderly were exercised using the biofeedback system (with functional electrical stimulation) three times a week for six weeks. Data analysis was performed using Wilcoxon signed rank test. Physical function improved significantly, but there was no significant difference in muscle strength and muscle mass. Although elderly people were able to confirm that community-based ICT home biofeedback training could be possible and could lead to improvements in the lower extremity function, further research is needed to demonstrate a clearer effect by expanding the target population, distinguishing the sexes, and providing a personalized training method.

This study was conducted through a focus group interview of 4 teams of 40 nursing students to provide basic data for the development of customized cadaver practice programs and life and nursing ethics education by identifying the anatomical observation experiences of nursing students through cadaver. We tried to grasp the meaning and essence of the anatomical observation experience using the Colaizzi analysis method. As a result of the analysis, 3 categories, 6 theme clusters, and 12 themes were derived. The theme clusters for each category are as follows: Unrest (worry, confrontation), reflection (the boundary between life and death, teaching of the body teacher), growth (step forward, a valuable experience that will never be again). It was an opportunity for nursing students to realize the mystery of the human body and the preciousness of life through the experience of cadaver, and to consider the altruistic life through donation while recognizing that death is also a process of life in a broad sense.

This study explored the security of Industry 4.0 such as security trends and security threats in Industry 4.0, and security system in Industry 4.0. The threat elements in Industry 4.0 are changing from ICT to IoT and to CPS security, so security paradigm and security System should change accordingly. In particular, environmental and administrative security are more important to solve CPS security. The fourth industry-age security should change to customized security for individual systems, suggesting that the security technology that combines hardware and software in product production design should change from the beginning of development. The security system of the fourth industry proposes design and implementation as a CPS security system as a security system that can accommodate various devices and platforms from a security system in a single system such as a network to an individual system.
