Purpose: The objective of this study was to examine the correlation between HbA1C, self-care behavior, and quality of life among depressed and non-depressed patients with type II diabetes Methods: Data were collected between May 26 and July 5, 2011 using a questionnaire. The questionnaire included depression (CES-D), self-care behavior and quality of life. Hemoglobin A1C was ed from medical records. Data were analyzed by descriptive statistics, t-test, $x^2$-test, ANCOVA and Pearson's correlation coefficient. Results: In this study sample (n=301), 20.9% of diabetic patients (n=69) were depressed. After adjustment for relevant covariates, depressed patients showed to have lower self-care behavior (2.8 vs 3.4, p<.001) and quality of life (2.8 vs 3.5, p<.001) scores, but the difference in HbA1C was no longer significant. Conclusion: This study suggests that the assessment and intervention for depressed diabetic patients can result in effective self-care behavior, which accordingly leads to improvement of the quality of life.

Purpose: The study aimed to validate a structural model of self-concept among children and adolescents from multicultural families. Methods: Data were collected from 325 mothers of multicultural families and their 417 children. Confirmatory factor analysis, path analysis and multiple mediation analysis with a phantom variable approach were used to assess construct validity and relations between model variables. Results: Goodness of fit indices of the modified theoretical model, the standardized ${\chi}^2$ (2.75), RMR (.02), RMSEA (.07), NFI (.90), TLI (.92), CFI (.94), GFI (.89), and AGFI (.87), met criteria. Social support and mental health problem had significant direct effects on self-concept, whereas residential environment and school adjustment had significant indirect effects, accounting in combination for 53% of the variance in self-concept. Conclusion: Based on the results, mental health problem mediated the relationships of self-concept and parenting stress.

By using the conceptual impedance and the elasticity of a serial chain of spring-damper system, a real-time collision-free trajectory generation algorithm is proposed. The reference points on a trajectory connected by the spring-damper system have a mechanism for self-Position adjustment to avoid a collision by the impedance, and the local adjustment of each reference point is propagated through the elasticity to a real robot at the end of the spring-damper system. As a result, the overall trajectory consisting of the reference points becomes free of collision with environmental obstacles and efficient having the shortest distance as possible. In this process, the reference points connected by the spring-damper system take role of virtual robot as global guidance for a real robot, and a cooperative optimization is carried out by the system of virtual robots. A control algorithm is proposed to implement the impedance for a car-like mobile robot.

A two dimensional Darrieus-type turbine has been proposed for the hydropower utilization of extra-low head less than 2m. In a practical use of Darrieus-type hydro-turbine, head and flow rate may be varied temporally and seasonally. Considering that the cost advantage is required for the low head hydro turbine system, the Darrieus turbine should be operated with high efficiency in the wider range of flow rate possibly by using an additional device with simpler mechanism. In the present paper, an adjustment of inlet nozzle section by lowering the inlet nozzle height is proposed to obtain the preferable inlet velocity in low flow rate conditions. Effects of resulting spanwise partial inlet flow are investigated. Finally, an effective modification of inlet nozzle height over flow rate variation is shown.

This paper focuses on self-organization of fuzzy rules for performance management of computer communication networks serving manufacturingsystems. The performance managment aims to improve the network performance in handling various types of messages by on-line adjustment of protocol parameters. The principle of fuzzy logic has been used in repressenting the knowledge of human expert on the performance management and in deriving manafement decisions. In this paper, we present an of this self-organization is domonstrated by discrete simulation of an IEEE 802.4 network.

본 연구에서는 초등학생을 위한 해결중심 집단상담프로그램의 효과크기를 통합하여 제시하고, 보다 효과적인 해결중심 집단상담프로그램에 대한 실천적 방안을 제시하기 위하여 메타분석을 실시하였다. 자료 수집은 2014년 5월까지 국내에서 발표된 석 박사 학위논문 및 학술지에 게재된 논문 중 메타분석의 대상선정기준에 따라 논문을 선정하여 분석하였다. 메타분석을 위해서는 CMA(Comprehensive Meta-Analysis) software 2.0을 사용하였으며, 연구의 주요 결과는 다음과 같다. 첫째, 초등학생을 대상으로 국내에서 실시된 해결중심 집단상담프로그램의 평균효과크기를 살펴보면, 자아존중감의 효과크기가 1.61으로 가장 높게 나타났고, 학교적응능력이 1.35, 대인관계능력이 1.07, 자기효능감이 1.03 의 순으로 나타나서 네 가지 변수 모두 큰 효과크기를 보였다. 둘째, 해결중심 집단상담프로그램의 효과크기가 조절변수에 따라 어떻게 차이가 나는지 살펴보았다. 통계적으로 유의미한 조절변수는 자아존중감의 경우에 '총회기수'이었고 학교적응능력의 경우에는 '총회기수'와 '1회기당 시간'으로 나타났다. 본 연구결과를 바탕으로 초등학생을 위한 해결중심 집단상담프로그램의 실천적 함의와 전략을 제언하였다.

본 연구는 중학생의 성취가치로 학업적응을 예측함에 있어서 자기조절의 매개효과와 진로정체감의 조절효과를 알아보는 데에 그 목적이 있다. 연구대상은 중학교 3학년 남학생 1088명과 여학생 970명이다. 연구방법은 SPSS와 hayes의 process macro를 사용하여 조건부과정분석을 실시하였다. 본 연구의 결과는 다음과 같다. 첫째, 성취가치와 학업적응 간의 관계에서 자기조절의 부분매개효과는 유의한 것으로 나타났다. 둘째, 성취가치와 자기조절 및 성취가치와 학업적응 간의 각 관계에서 진로정체감의 조절효과는 모두 유의한 것으로 나타났다. 끝으로, 성취가치가 자기조절을 경유하여 학업적응에 영향을 미치는 매개효과의 크기는 진로정체감의 수준에 따라 조절되는 것으로 나타났다. 이러한 결과는 성취가치가 낮은 중학생에게 진로정체감을 개발하도록 지원하는 것이 자기조절과 학업적응의 향상에 도움이 된다는 것을 보여준다. 그러나 진로정체감의 영향이 성취가치나 자기조절의 영향보다 낮은 것으로 나타났으므로, 향후 연구를 통하여 성취가치를 높이도록 지원하기 위한 방안을 강구할 것을 제안한다.

Objectives : The purpose of this study was to examine the self-esteem and job-seeking efficacy of dental hygiene students in an attempt to provide some information on career guidance, counseling and the development of employment programs by colleges, as self-esteem seemed to be one of integral variables to affect job-seeking efficacy. Methods : The subjects in this study were the dental hygiene students in three different colleges in South and North Jeolla Provinces. After a self-administered survey was conducted, the answer sheets from 562 respondents were analyzed by the SPSS(Statistical Package for the Social Science) WIN 12.0. Results : 1. The students investigated got a mean of 2.43 in self-esteem, which was not a high score. The sophomores had a better self-esteem than the freshmen and juniors, and the gaps among the respondents in each subfactor of self-esteem were significant($p^*$ <0.01, $p^{**}$ <0.05). 2. The students got a mean of 3.12 in overall job-seeking efficacy, and there were significant differences among them in each subfactor of job-seeking efficacy($p^*$ <0.01). 3. The freshmen were ahead of the sophomores and juniors in job-seeking efficacy, and the gaps between the former and the latter were significant($p^*$ <0.01). 4. There was a significant relationship between the self-perceived self-esteem and job-seeking efficacy of the students. A higher self-esteem led to a better job-seeking efficacy(p<0.01). Conclusions : The above-mentioned findings illustrated that a higher self-esteem had a more positive effect on job-seeking efficacy. Therefore the development of programs geared toward boosting the self-esteem of dental hygiene students is required, and educational institutions should provide quality self-esteem programs for students to plan and prepare for their future, to make the right career choice, to improve their vocational adjustment, to keep pursuing self-development and to build the right values.
