Unlike the feature of SNS, which strengthens two-way communication and promotes interaction through consistent on/off line identity management, passive use of Facebook to unilaterally accept other people's opinions is being strengthened, and more people tend to use Facebook anonymously or pseudonym to enjoy freedom of expression. To illustrate this transformative use behavior, this study suggests an integrated model including psychological and behavioral variables such as self-esteem, real name use, and opinion expression to explore the effect on social relationship value perception and satisfaction. Studies have shown that self-esteem affects the use of real names and self-exposure, and that the satisfaction and sustainability of relationships have increased as real-name users expose more information about themselves.

In this paper, we propose a novel method to enhance the harmonic components from the frequency lines of the passive sonar signals. For this, we first separate the stable frequency lines from unstable ones using mean and difference of spectral bins in the vernier analysis. Then we emphasize the harmonic components using autocorrelation-based postprocessing, and enhance them by reducing the background noise with the split-window two pass mean algorithm. Experimental results for real underwater acoustic data are presented with our discussions.

The purpose of this study is to examine the associations among family cohesion, self-efficacy, and school adjustment in adolescence. This study investigated these interrelationships using structural equation modeling. The results indicated that family cohesion had effects on school adjustment both directly and indirectly through self-efficacy. The mediating effect of self-efficacy was statistically significant. These results imply that family cohesion and self-efficacy need to be emphasized as a strategy to improve school adjustment among adolescents.

Purpose: The purpose of this research was to develop and evaluate the effects of an empowerment program. Method: We developed an 8-week empowerment program to decrease cancer symptoms and increase self-efficacy, self-esteem, and empowerment. This program includes aspects concerning self-knowledge and management, self-help groups, self-advocacy, resource network, and laughter therapy. We evaluated the effects of this program on 32 home-based cancer patients (one group pretest-posttest design). The data collection was performed from August 22, 2011 to October 13, 2011. Data were analyzed using the SPSS/WIN 18.0 program. Result: There were significant differences in self-esteem derived from the empowerment program. However, there were no significant differences in cancer symptoms, self-efficacy, and empowerment after the program. Conclusion: More research, using a control group pretest-posttest design that considers an appropriate intervention duration, is needed to more accurately examine the effects of the program. We expect this intervention to improve the empowerment of home-based cancer patients.

Tensile properties of polypropylene based self-reinforced composites were investigated as a function of process variables of the double-belt lamination equipment such as pressure, temperature and cooling conditions. Elastic modulus was enhanced approximately 6 times from 0.2 to 1.2 GPa. The improvement mechanism was studied by identification of crystalline structure changes using DSC and XRD analysis. In addition, morphology change of self-reinforced composites was also investigated by SEM analysis in order to reveal the degree of impregnation.

Purpose: The purpose of this study was to identify the relationships beween depression, self-efficacy and, treatment adherence in peritoneal dialysis patients. Method: Participants were 139 in a hospital located B city Korea. The data were examined using descriptive statistics, t-test, ANOVA, and Pearson's correlation with SPSS 25.0. Results: Self-efficacy had positive correlation with medication(r=.28 p=.001), fluid restriction(r=.23, p=.008), dietary restriction(r=.38, p<.001) in adherence. Depression had a negative correlation with medication(r=-.17 p=.046), dietary restriction(r=-.17, p=.043) Conclusion: Nursing starategies to strengthen the treatment adherence of patients with peritoneal dialysis need to focus on enhacing self-efficacy and alleviating depression.

최근 4차산업혁명으로 산업계에 전반적으로 확산하고 있는 디지털트랜스포메이션과 코로나19로 인한 장기적인 경기 불황의 여파로 대응 역량이 제한적일 수밖에 없는 중소기업의 어려움이 갈수록 심화하고 있다. 중소기업은 기업의 성과를 높이기 위해 경영혁신과 함께 조직구성원들의 역량을 강화하기 위한 다양한 노력을 지속하고 있다. 이러한 중소기업의 성장과 조직구성원의 역량 향상은 국가 경제에 매우 중요한 의미를 가지고 있다. 이에 조직구성원의 자발적인 참여와 동기부여를 통해 직무만족도를 높이고 조직성과를 창출하려는 관심이 날로 높아지고 있다. 본 연구의 목적 역시 중소기업의 조직문화와 조직구성원의 자기효능감이 직무만족도와 어떠한 상관관계를 가지고 있는가를 조사하고 잡 크래프팅의 매개 역할 여부를 분석하는 데 있다. 본 연구에서는 조직문화와 자기효능감이 중소기업의 잡 크래프팅을 활성화하고, 활성화된 잡 크래프팅이 직무만족도에 영향을 미칠 것이라는 인과적 관계를 검증하고자 한다. 불확실한 경영환경 아래서 중소기업의 지속적인 생존과 성장을 위해 자기주도적으로 새로운 변화에 빠르게 대응할 수 있는 잡 크래프팅을 매개변수로, 그리고 조직구성원의 핵심 역량으로 요구되고 있는 직무만족도를 종속변수로 설정하여 본 연구를 진행하였다.

The purpose of this study was to verify the causal relationship between self-directed learning ability and career maturity by Middle and High School Students in Seoul. This study used Seoul Education Longitudinal Study(SELS) data. Using autoregressive cross-lagged modeling, the results was followed. first, self-directed learning ability value was had a statistically significant positive effect in accordance with the time course from middle school 1st grade to high school 3rd grade. Second, career maturity also had a statistically significant positive effect in accordance with the time course from middle school 1st grade to high school 3rd grade. Third, previous self-directed learning ability had significant positive effect on the later career maturity, but the previous career maturity had no significant effect on later self-directed learning ability.

The purpose of this study is to confirm the effect of health assessment classes applied with flip learning on self-directed learning ability, critical thinking disposition, and academic self-efficacy of nursing students. This is a comparative study before and after a single group, targeting sophomore students taking a health assessment by applying flip learning at a nursing college in K city, Gyeongsangbuk-do. The final analysis consisted of 104 subjects, and the pre-post difference was analyzed by a paired sample test. As a result, self-directed learning ability (t=-3.23, p<.01), critical thinking disposition (t=6.381, p<.001), and academic self-efficacy (t=-4.62, p<.001) were all statistically significantly increased. Based on the results of this study, it was confirmed that the flip-learning method is an effective program to enhance the self-directed learning ability, critical thinking ability, and academic self-efficacy of nursing students. In the long run, the application of the flipped learning learner will play a role in improving the educational environment and strengthening the abilities of students.

This study attempts to perform the statistical test for the causality between the Korean and the U.S. business conditions in association with the lead-lag relationship between the domestic stock price and the business condition. Their causal relationships are clearly identified after the outbreak of the IMF financial crisis. The vector autoregression for the corresponding period appears to reflect the strong interrelationships between the market variables and the dependency of the domestic business conditions on the U.S. market. The estimation results validate the leading effect of the stock price and the U.S. business behavior.
