본 연구는 청소년들의 폭력피해 경험이 우울정서와 자기인권평가의 매개과정을 통해 어떻게 인권의식에 영향을 미치는지를 검증하는데 목적을 두었다. 이를 위해 청소년 폭력피해와 인권의식의 인지적 정서적 과정을 설명한 선행연구와 이론적 논의를 토대로 연구모형을 설정하였다. 본 연구는 '2014년 한국아동 청소년 인권실태조사'의 중학생 자료 3,662명 사례를 활용하였으며, 구조방정식모형을 통해 분석하였다. 구조모형 분석결과에 의하면, 첫째 폭력피해경험은 인권의식에 직접적인 효과는 없었지만, 자기인권평가의 매개적 과정을 통해 인권의식에 간접적으로 영향을 미쳤다. 둘째, 폭력피해경험은 우울과 자기인권평가의 이중매개 과정을 통해서도 간접적으로 인권의식에 영향을 미쳤다. 셋째, 통제변수인 인권교육은 인권의식에 직접적인 효과는 없었고, 자기인권평가의 매개과정을 통해서 인권의식에 간접 효과를 나타냈다. 본 연구는 이러한 결과를 토대로 폭력피해 청소년들의 인권의식 증진을 위한 개입방안과 후속연구를 위한 과제를 논의하였다.

When a human operator interacts with a virtual wall that is modeled as a virtual spring model, the lager the stiffness of the virtual spring is, the more realistic the operator feels that the virtual wall is. In the previous studies, it is shown that the maximum available stiffness of a virtual spring to guarantee the stability can be increased when the first-order-hold method is applied, however the effects of a human impedance on the stability are not considered. This paper presents the effects of a human impedance on stability of haptic system with a virtual spring and a first-order-hold (FOH) method. The human impedance model is modeled as a linear second-order system model. The relations between the maximum available stiffness of a virtual spring and the human impedance such as a mass, a damping and a stiffness are analyzed through the MATLAB simulation. It is shown that the maximum available stiffness is proportional to the square root of the human mass or damping respectively.

The purpose of this study is to develop a group counseling program for career exploration and to explore its effects on college students' self-efficacy. Main program activities consisted of 8-week sessions. Equivalent control group pretest-posttest design was employed for this study. 40 college students voluntarily participated in a group counseling of career exploration. Another 40 students were selected for a control group of this study design. The self-efficacy (23 items) was administered to both the experimental and the control groups before and after the 8-week treatments. The results of this research showed that the differences (program effects) of the experimental group in the scale were higher than those of the control group. In conclusion, a group counseling program for the career exploration had significant effects on the career exploration and self-efficacy of college students.

본 연구는 전국의 노인장기요양시설 종사자의 인권의식과 인력형태가 복지서비스질에 영향을 파악하고, 종사자의 자기효능감의 매개효과를 분석하고자 하였다. 연구결과로는 첫째, 인권의식은 서비스 질에 유미한 영향을 미치는 것으로 나타났으나, 인력형태는 유의미한 영향력이 나타나지 않았다. 둘째, 자기효능감의 매개 효과는 부분적으로 지지가 되었는데, 자기효능감의 하위요인인 자신감과 과제선호도의 경우 인권의식과 서비스 직 간에 매개 효과가 유의하게 나타났다. 이러한 결과를 기반으로 노인장기요양시설 종사자의 인권의식을 향상시키기 위해 인권 감수성을 높이는 교육 체계를 정비할 것과 인권에 대한 보수교육으로 전문성을 확보할 것을 제언하였다.

The share of the population that is aging is growing rapidly. In an aging society, technologies and interventions that delay the aging process are of great interest. Dietary restriction (DR) is the most reproducible and effective nutritional intervention tested to date for delaying the aging process and prolonging the health span in animal models. Preventive effects of DR on age-related diseases have also been reported in human. In addition, highly conserved signaling pathways from small animal models to human mediate the effects of DR. Recent evidence has shown that the immune system is closely related to the effects of DR, and functions as a major mechanism of DR in healthy aging. This review discusses the effects of DR in delaying aging and preventing age-related diseases in animal, including human, and introduces the molecular mechanisms that mediate these effects. In addition, it reports scientific findings on the relationship between the immune system and DR-induced longevity. The review highlights the role of immunity as a potential mediator of the effects of DR on longevity, and provides insights into healthy aging in human.

Purpose: The purpose of this study was to examine the effects of Self-Development training on the Human Relationship and Intrinsic Motivation for first-line nurse managers. Method: This was an empirical study on the Human Relationship and Intrinsic Motivation of Self Development Training. The researcher developed a new Self-Development Training Program, and the two-hour long training session was performed twice a week for each group. The program was performed for 4 session in two weeks. The subjects consisted with 24 nurse managers from C University Hospital in Seoul, Korea. The subjects were divided into two groups for the training. Two weeks before and 4 weeks after the training, subjects completed questionnaires that measured Human Relationship and Intrinsic Motivation. Analysis was completed by using SPSS PC 10.0 for percentile, mean, standard deviation and paired t-test. Result: The results of this study showed that Self-Development Training Program resulted in a significant effects on the Human Relationship. But the Intrinsic Motivation was not significantly affected by the program. Conclusion: This Self-Development training program had a positive effect on the Human Relationship and Intrinsic Motivation.

This study examines the effects of purple Kohlrabi fresh and peel ethanol extracts on the antioxidative activity and antiproliferation of human cancer cells (Hep G2 human liver, HCT-116 human colon, and A549 human lung cancer cells.) The total flavonoid and anthocyanin content of purple Kohlrabi ethanol extracts were much greater in the peel than in the flesh. The DPPH radical scavenging activity and antioxidative index of purple Kohlrabi peel extracts were similar to those of the BHA and the BHT. Antiproliferation effects of purple Kohlrabi peel extracts on human cancer cells (Hep G2, HCT-116, and A549) strengthened in a dose-dependent manner. In particular, the antiproliferation activity of purple Kohlrabi peel extracts exceeded 40% in colon cancer cells. These results indicate that the purple Kohlrabi peel may contain bioactive compounds such as flavonoids as well as anthocyanin and that these compounds may facilitate cancer prevention.

This study was performed to determine the antimutagenic and cytotoxic effect of the Phellinus linteus methanol extract on Salmonella typhimurium TA98, TA100 and human cancer cell lines. In the Ames test, methanol extract of P. linteus alone did not exhibit any mutagenicity but showed substantial inhibitory effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine(MNNG), 4-nitroquinoline-nitroquinoline-1-oxide(4NQO), 3-amino-1,4-dimethyl-5H-pyrdo[4,3-blindol(Trp-P-1) and benzo(α)pyrene(B(α)P). The methanol extracts of P. linteus(200㎍/plate) showed approximately 78.3%, 78.7% and 88.1% inhibitory effect on the mutagenesis induced by 4NQO, Trp-P-1 and B(α)P. The anticancer effects of P. linteus extract against human breast adenocarcinoma(MCF7), human lung carcinoma (A549), human fibrosarcoma (HT1080), human hepatocelular carcinoma (Hep3B) and human epitheloid carcinoma (HeLa) were investigated. The treatment of 1mg/mL P. linteus extracts had the highest cytotoxicity against MCF7 (92.0%), followed by Hep3B (84.9%), A549 (84.2%) and HT1080 (82.9%). In contrast 1mg/mL treatment of P. linteus extracts had only 10∼40% cytotoxicity on normal human liver cell (WRL68).

Purpose: This study was conducted to examine the effects of an intervention program for human tissue donation with nurses, modified from the Korea Foundation for Human Tissue Donation, to promote human tissue donation via nurses' knowledge and attitudes toward human tissue donation, and self-efficacy for teaching tissue donation. Methods: A non-equivalent control group quasi-experimental design was adopted, and data were collected from 82 nurses (41 of each group: experimental and comparison) working at a general hospital in Inchon, South Korea. Results: In a multivariate analysis (MANOVA), the integrative effect on outcome variables from the intervention program was statistically significant (p<.001). Accordingly, an ANOVA was performed to determine which individual outcome variable showed a significant effect with intervention, and it was found that the effects of intervention on all the outcome variables (knowledge and attitude, and self-efficacy for teaching human tissue donation) were significant (p<.001). Conclusion: The results of the study showed that the intervention had positive effects on knowledge and attitudes toward tissue donation, and self-efficacy for teaching tissue donation among nurses. These outcome variables derived from the intervention might be essential for eliciting positive behavior toward human tissue donation.
