Purpose: The purpose of this study was to review interventions available to nurses caring for siblings of children with cancer. Methods: Searches of CINAHL, MEDLINE, PubMed, EMBASE, and RISS identified ten intervention studies published from January, 2000 to November, 2016. Results: Ten studies on interventions for siblings of pediatric cancer patients were identified as follows: 4 included camps, 4 included support groups, and 2 provided individual interventions. Theoretical frameworks were mainly cognitive behavioral theory and most studies were led by psychologists and multidisciplinary teams. The purpose of the interventions was primarily enhancing psychosocial adjustment. Siblings' fear of disease, self-esteem, and social support were improved significantly after the interventions. Findings were inconsistent with regard to depression, anxiety, behavioral problems, post-traumatic stress, health-related quality of life, and siblings' perceptions of the illness. Conclusion: Study findings showed the potential for enhancing emotional and behavioral outcomes in siblings of children with cancer. However, the number of studies was very small, and several methodological limitations were identified. In the future, more randomized controlled trials with larger samples are needed to extend the evidence base. Moreover, future research should identify sibling's characteristics and circumstances most likely to bring benefits to the siblings.

Micron-sized metal wires are widely used in industries such as filtration, catalyst and composite materials, etc. In the wire drawing process, the die that is used conventionally is an effective and, at the same time, sensitive component. However, a typical array of the dies has caused many problems in the wire drawing process, e.g., large frictional force on the interface between wire and the resulting high heat generation, precise adjustment of the dies, extended cooling system, die abrasion, etc.. Because of these problems, there have been many works that are aiming at improving the efficiency of wire drawing process by analyzing the die geometry and by applying advanced die material to prolong the die life or even at developing a dieless wire drawing system. This paper is dealing with developing a new wire drawing system that is applicable to reduce the wire drawing steps with high draw ratio. The new wire drawing system does not use the dies, but use the self-induced heater that works on the basis of the resonant phenomenon of wire material. The electromagnetic wave is the heating source. The results of the study on the diameter reduction and microwave flow analysis show that the heating effectiveness of the wire is influenced by the energy distribution in the microwave propagation chamber. We can obtain diameter-reduced wires by using microwave in the dieless drawing process. Microwave as a heating source is capable of producing wires without applying dies in wire drawing process.

Objectives : This cross-sectional study aimed to quantify the relationship between the bone mineral density at the os calcis and the body mass composition in healthy children. Methods : The areal bone mineral density was measured at the os calcis with peripheral dual energy X-ray absorptiometry. The fat free mass, fat mass and percentage fat mass were measured using bioelectric impedance, in 237 Korean children, aged 9 to 12 years. The sexual maturity was determined by self assessment, using standardized series of the 5 Tanner stage drawings, accompanied by explanatory text. Results : From multiple linear regression models, adjusted for age, sexual maturity and height, the fat free mass was found to be the best predictor of the calcaneal bone mineral density in both sexes. About 15 and 20% variabilities were found in the calcaneal bone mineral densities of the boys and girls, respectively, which can be explained by the fat free mass. After weight adjustment, the percentage fat mass was negatively associated with the calcaneal bone mineral density in both sexes. Conclusions : The findings of this study suggest that the fat free mass, among the body compositions, is the major determinant of bone mineral density at the os calcis in Korean children aged 9 to 12 years. Obesity, defined as the percentage fat mass, is assumed to have a negative effect on the calcaneal bone density in children of the same weight.

본 연구는 조기진급 및 조기졸업제를 활성화하기 위해 지금까지 교육현장에서 본 제도를 적극적으로 활용하지 못하는 이유를 학생의 사회 정서적 측면에 초점을 두어 분석하고 실증적으로 자료를 제시하였다. K 대학교에 재학 중인 52명의 학생을 대상으로 자아존중감검사(Coopersmith, 1967, 1981, 1984)와 학교생활에 대한 지각검사(이미순, 이현주, 2006)를 실시하였다. 조기진급 및 조기졸업의 유무에 따른 자아존중감을 연구하기 위해 학생의 GPA를 공변량으로 설정한 후, 다변량 공분산 분석(MANCOVA)를 실시하였고, 대학에 입학하기 전 고등학교 생활에 대한 지각의 차이는 다변량 분산 분석(MANOVA)를 통해 조사하였다. 연구결과, 사회 정서적측면에 대한 우려와 달리 조기진급 및 조기졸업에 의한 자아존중감에서 유의한 집단간 차이는 나타나지 않아, 조기진급 및 조기졸업을 한 후 대학에 입학한 학생들이 자신을 부정적으로 지각하지 않는 것으로 나타났다. 오히려 조기진급 및 조기졸업자들이 일반적으로 자신을 보다 긍정적으로 지각하였고, 고등학교 재학 중에 조기졸업에 대한 기회와 정보가 많았다고 응답하였다.

Korea is becoming a model country for the developing countries' agricultural and rural development. Drawing implications for Vietnam from Korea's experiences can help make development strategies and policies for other developing countries including North Korea as well as for Vietnam itself. Vietnam is facing an inefficiency in agricultural production and the gap between urban and rural growth has been widening. Farm sizes per household are small and farmlands are scattered. Diversification in rural industry is very restricted. To attack these problems, investment is urgently needed for rural infrastructure building as well as agricultural structure adjustment. In the process of rural development, there have been also encountered such problems as financial procurement, community's spontaneous participation, manpower development for adjusting to industrial structural change. Korea's experiences may be helpful for establishing rural development strategies and policies in Vietnam. Benchmark scopes can go beyond Saemaul Undong in 1970s. Korea's pre- and post-Saemaul Undong era as well as the Saemaul Undong era can be referred. In the wake of globalization, Vietnam has not only experienced compressed rapid economic growth but also encountered policy tasks to eradicate poverty, to realize self-reliance and income increase, and to lessen urban-rural development gap, at the same time. Korea's experiences show that priority needs to be put on the establishment of national and rural development strategies based on Vietnam-specific conditions, utilization of village's resources including community tradition and social capital, fund raising for rural development, farmland development and mobilization, production and living infrastructure building, technology transfer for farmers and vocational training for new job seekers.

열차제어시스템의 소프트웨어 발전에 의해 PES가 사용되고 있다. PES는 현재 세계적으로 널리 사용하고 있고, 하드웨어, 펌웨어, 응용 소프트웨어로 구성되어 있다. PES의 실행이 높은 유연성을 가지고 있기 때문에 PES는 많은 응용분야에 쉽게 적용할 수 있다. 많은 안전 필수 기능들은 소프트웨어를 통해 수행되고 있다. 보통 PES는 매우 복잡하여 결함의 근원을 발견하기 쉽지 않다. 그래서 소프트웨어 결함허용 기법을 이용한 신뢰도 해석이 필요하다. 현재 소프트웨어 결함허용 기법에는 복구블록, 분산 복구 블록, N-버전 프로그래밍, N 자기검사 프로그램이 있다. 본 논문에서는 마르코프 모델을 이용하여 소프트웨어 결함허용 기법 중에 복구 블록과 N-버전 프로그래밍의 모델을 제시하였다. 또한 열차제어시스템의 신뢰도를 시간 변화에 따라 분석하였다. 프로그램의 결함 발생률, 수용테스트 결함발생률, 보터의 결함발생률은 고정시켰다. 그래서 시간과 신뢰도 사이의 관계를 Matlab 프로그램을 이용하여서 제시하였다. 같은 수의 대체블록이 있는 경우에 신뢰도 분석결과 복구 블록의 신뢰도는 N-버전 프로그래밍의 신뢰도보다 높게 해석되었다.

Purpose: The present study was intended to measure fatigue symptoms according to the quality of sleep among nurses working for an university hospital and to reveal its related factors. Methods: The self-administered questionnaires were given to 397 nurses employed in an university hospital located in Daejeon City during the period from June 1st to July 31st, 2007. Results: The group with higher quality of sleep accounted for 78.1% of all the subjects and the one with lower quality, 21.9%. According to qualities of sleep, the fatigue symptom was determined to be significantly higher in the group with lower quality of sleep than its counterpart. On adjustment for quality of sleep, the level of fatigue symptom was significantly higher in the groups, than in each respective counterparts, who don't take regular exercises, who have few leisure time, who have lower level of subjective health status, who range ${\geq}$ 1 and < 10 years in job careers, who work in shifts, who reported that it is hard to get physical burden of work, who are satisfied with the job, who find themselves unfit to the job, who are considering quitting the job, who have higher job demand, who have lower job control, who have higher level of supervisor support, who have type A behavior pattern. Conclusion: The study results may explain that the fatigue symptom of nurses is highly associated with the quality of sleep independently of other variables and also with job-related characteristics independently of the sleep quality. In conclusion, to reduce the fatigue symptom of nurses, strategic efforts should be directed for programs to improve the quality of sleep and a proper job analysis.

한국사회가 저출산 고령화와 고학력화의 추세, 전지구화, 지식정보화라는 세계적인 흐름을 고려할 때 앞으로도 향후 지속적인 이주인구의 유입은 불가피한 실정이다. 특히 결혼이민자들은 한국사회에서 적응하기 위한 언어와 문화적 적응을 극복하지 못한 상태에서 그들 자녀들을 교육해야 되는 열악한 환경적인 문제에 봉착하게 된다. 더구나 다문화가족 자녀는 2008년 5월을 기준으로 58,007명으로 전체 외국인 주민의 6.5%를 차지하며 다문화가족의 자녀 중 6세 이하가 57.1%로 상당히 높은 비율을 차지함을 고려해볼 때 현재 초 중등학생들을 대상으로 하는 연구는 시사점이 크다고 하겠다. 특히 전남지역의 다문화가족은 전국 최고의 비율을 차지하고 있으며 총 5,919 가족 중 영유아기와 학령기에 포함되어 있는 다문화가족 자녀 재학생수는 1,479명으로 집계되고 있다(행정안전부, 2008). 이렇게 교육대상자로서 점점 증가하고 있는 다문화가족의 학생들이 전남지역에 상당수 집중되어 있다. 이렇게 유입되는 이주자 중 결혼이민으로 인한 그 자녀의 자아존중감과 학교생활적응은 주요한 사회문제로 대두되고 있다. 그간의 연구들의 대부분은 이주여성의 생활실태와 일상에서 겪는 다양한 문제점에 초점을 맞추고 있을 뿐 그들 가정의 자녀들에 대한 연구는 미흡한 편이다. 이 연구는 2차 사회화 과정에 결정적인 영향을 미치는 학교생활에서 다문화가족 학생들의 자아존중감과 학교생활적응에 관하여 전남 동부지역 일부를 초 중등교사들을 대상으로 어떻게 인지하고 있는지를 연구하였다. 연구방법은 교사들을 대상으로 구조화된 설문지를 이용하여 인구학적 특성, 다문화가족 학생들의 자아존중감 및 학교생활적응 관련 인식들을 조사하였다. 자료분석은 SPSS Win 12.0을 사용하여 빈도분석, t-test 및 일원배치 분산분석을 실시하였다. 교사의 성별, 학교급 별, 농촌과 도시지역, 학교규모, 학년, 교육경력에 따라 유의미한 차이가 있는 것으로 나타났다.
