Purpose: The purpose of this study was to identify the influencing factors on anxiety of patients who had received hemopoietic stem cell transplantation(HSCT). Method: A total of 81 patients who had undergone a HSCT at a university hospital were recruited from July of 2001 to June of 2002. They were asked to complete questionnaires about anxiety, self-esteem, family support, doctor's support and nurse's support. Result: The mean score of anxiety, self-esteem, family support, doctor's support and nurse's support was 41.9, 3.0, 4.6, 7.6 and 7.3, respectively. A significant negative correlation was found between anxiety and self-esteem. Self-esteem was positively correlated with family support, doctor's support and nurse's support. The major variable that influenced anxiety was the self-esteem, explaining 25.4% of the anxiety. Conclusion: On the basis of these results, it is necessary for HSCT patients to develop a nursing intervention for the enhancement of self esteem. Also, family support, doctor's support and nurse's support should be considered as a main support system in the nursing strategy for improving the quality of life of patients undergone HSCT.

Purpose: The purpose of this study was to examine the relationship between test anxiety, self-esteem and mental health. Method: Data were collected by structured questionnaires from 306 nursing students in a dormitory for the national examination for registered nurses. Collected data were analyzed by t-test, ANOVA, scheffe's test and Pearson's correlation coefficient and hierarchial multiple regression through the SPSS WIN program. Result: The results of the analysis showed that the mean for test anxiety was $79.70{\pm}18.74$ points, the degree of self-esteem was $28.26{\pm}5.02$, and mental health was $24.31{\pm}13.07$. In the correlation analysis, mental health positively correlated with test anxiety (r=.559, p=.000) and negatively correlated with self-esteem (r=-.141, p=.013). Test anxiety and subjective health status explained 36.4% of mental health. Conclusion: This finding of this study recommends that test anxiety control and self-esteem enhancement programs should be development for mental health promotion in nursing students taking the national examination for registered nurses.

Purpose: The purpose of this study was to develop a heart health diary to promote self-care ability among patients with heart failure (HF), and to identify the diary's effect on self-care adherence, self-efficacy, and physical activity. Methods: A randomized control-group pretest-posttest design was adopted using block randomization. A calender-typed health diary was developed and it included a self-care checklist and education information on HF management. The experimental group were given guided counseling and education for 8 weeks and wrote a daily health diary during that period. Data were collected from the outpatient department of a tertiary medical center from February to April 2016. To verify the hypotheses, data for the experimental group (n=28) and control group (n=33) were analysed using the independent t-test with SPSS/WIN 21.0. Results: At the end of 8 weeks the experimental group had significantly higher scores for self-care adherence (t=-2.48, p =.016) and exercise related self-efficacy (t=-3.44, p =.001) compared to the control group. Conclusion: The findings show that the application of a patient-directed heart health diary is an effective nursing intervention for improving HF patients' self-care adherence and exercise self-efficacy. Strategies to promote dietary self-efficacy are necessary along with further studies including repeated research with an increasing intervention period. Healthcare providers need to encourage the utilization of a health diary for HF patients as a tool for evaluation and for implementation that leads to self-care.

The development of a light-weight vehicle is in great demand for enhancement of fule efficiency and dynamic performance. The vehicle weight can be reduced effectively by using lightweight materials such as aluminum and magnesium. However, if such materials are used in vehicles, there are often instances when different materials such as aluminum and steel need to be joined to each other. The conventional joining method, namely resistance spot welding, cannot be used in joining different materials. Self-piercing rivet(SPR) and adhesive bonding, however, are good alternatives to resistance spot welding. This paper is concerned with the crushing test of double hat-shaped member made by resistance spot welding, SPR and adhesive bonding. Various parameters of crashworthiness are analyzed and evaluated. Based on these results, the applicability of SPR and adhesive bonding are proposed as an alternative to resistance spot welding.

In this study, an effective fluorescence pH sensor based on conjugated polyelectrolyte micelles (CPMs) was devised for detecting extremely acidic conditions. An amphiphilic coumarin derivative (CC12-N), a building block, was prepared, into which an ionizable amino group, aryl amine, was incorporated as a potential hydrophilic moiety. This monomer displays self-assembled micelle formation in extremely acidic pH ranges, giving a hydrophobic π-extended conjugated system at the inner part and hydrophilic functionality at the periphery, resulting in efficient fluorescence intensity enhancement. This new micelle-based fluorescence provides an efficient sensing platform for detecting very low pH values in the presence of competing substances.

A comprehensive program for children's leadership improvement by enhancing their self-esteem, empathy, communication competence and emotion regulation utilized core concepts and techniques or the Solution-Focused Model of Chung et al. (2005), Satir's Experiential Model(Chung, 2003), Cognitive-Behavioral Model (Kim, 2002) and problem-solving games (Chung & Kim, 2005). Twenty-six $3^{rd}$, $4^{th}$, and $5^{th}$ graders from public schools in Seoul participated in six 2.5 hour sessions and their mothers participated in two 2.5 hour sessions. All subjects received pre-, post- and follow-up tests. The results showed that children's self-esteem, empathy, communication competence, and emotion regulation increased as a result of this program and the effects lasted for at least three months after the termination of the program.

We study on the segregation reduction effect of Self-Leveling Color Mortar by using variable composition set of plasticizer and thickener, Naphthalene, melamine and polycarbonate-based dispersants were employed as plasticizers for examining on fluidity of mortar mixtures. For enhancement of mortar stability without loss of it's fluidity, two types of thickener were used such as polysaccharide(PS) and hydroxyethylcellulose(HEC). As a result, the most effective mortar was composed by feeding 0.519% of polycarbonate-based dispersant with 0.002587% of PS and 0.155844% of HEC on amount of basic mortar.

본 연구는 다양한 관계에서 위축되고 의사소통이나 표현의 어려움을 갖고 있는 해체 다문화가족 아동들을 대상으로, 이들의 자아존중감 향상을 위한 지시적 개별모래상자놀이 프로그램을 개발하고, 그 효과성을 살펴보는 데 목적이 있다. 양적분석 데이터 수집을 위해 지시적 개별모래상자놀이를 통한 프로그램 사전 사후에 점수를 비교하였고, 수집된 자료의 통계처리로 SPSS 18.0 Package 프로그램을 사용하였다. 질적 분석을 위해 회기 내 B아동의 언어적 변화를 자기표현척도에 위해 수집하고 분석하였다. 연구기간은 2017년 2월부터 5월까지 약 3개월간 총 12회기 개별 활동과 1회의 집단 활동, 1박2일의 가족캠프 활동으로 총 6명의 아동을 대상으로 단일집단 사전사후 설계의 방법을 활용하였으며, 본 연구의 주요결과는 양적으로 지시적 개별모래상자놀이 프로그램을 통해 사회적 자아존중감 능력에서 z=-2,200으로서 p<.05보다 수준에서 유의미한 차이를 보였고, 질적으로 아동 B의 회기별 언어적 표현이 회기가 진행될수록 긍정적 표현이 증가하고, 부정적 표현은 감소하는 것으로 나타났다. 이는 무엇보다도 주제를 제시하는 지시적 개별 모래 상자의 접근방법과 더불어 가장 안정적 환경인 아동의 집으로 방문하는 과정이 해체 다문화가족 아동의 자아존중감 향상을 증가시키는 효과성을 보이는 것을 의미한다. 본 프로그램을 바탕으로 하여 다양한 내담자 특성에 따라 지시적 접근방법을 통한 이동형 개별적 모래상자 프로그램으로 가는 전초적인 기본 틀이 마련 될 것이다.
