Purpose: This study was conducted to investigate the correlation between degrees of health promotion behaviors and life satisfaction and effects of health promotion behaviors on life satisfaction in rural elderly women living alone. Methods: A descriptive correlation study was conducted with 189 rural elderly women living alone aged 65 or older in four senior counties in Jeollanam-do. Descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation, and multiple regression. Results: The subjects' health promotion behaviors and life satisfaction were significantly positive. Among the factors influencing the subjects' life satisfaction, nutrition and diet showed the greatest positive effects, followed by exercise and activity, and drinking and smoking. Among them, drinking and smoking had significantly negative influence. Conclusion: Among the health promotion behaviors that influenced life satisfaction, nutrition and diet, exercise and activity, and drinking and smoking were most significant factors. Therefore, this study provided basic data for improving the life satisfaction among rural elderly women living alone.

On January 30, 2012 an auxiliary component of Byron Unit 2 was tripped on bus under voltage. The cause of the event was the failure of the C-phase insulator track for the Unit 2 station auxiliary transformer(SAT) revenue metering transformer. In addition to this event, other events have occurred at other plants resulting in an open-phase condition.[1] Therefore, Nuclear Regulatory Commission(NRC) has requested that not only nuclear power plant(NPP) operating company but also its Design Certification(DC) applicant have to prepare open-phase detecting system in their operating plants and design document. In this paper, various open-phase conditions are simulated in NPP using Electromagnetic Transient Program(EMTP) and Atpdraw, and open-phase condition detecting system is proposed for Main Transformer(MT), Unit Auxiliary Transformer(UAT) and SAT connected power line in NPP.

To realize channel cross-connecting in optical communications systems, a high speed optical matrix switch was fabricated using z-cut $LiNbO_3$. For switch fabrication was design bending structure and coupling length and four $2{\times}2$ directional couplers were integrated on one substrate far construction of a $4{\times}4$ switch. Single-mode optical waveguides were formed by Ti-diffusion at a wet $O_2$ atmosphere. Ti-diffusion profile, refractive index variation and waveguide morphology were analyzed by Prism coupler and optical microscopy, respectively.

본 연구는 부모 이혼 후 재혼(동거)가정 자녀의 계부모에 대한 호칭을 둘러싼 갈등을 자녀의 시각에서 탐색하고자 하였다. 이를 위해 심층면접을 활용한 질적 연구방법을 사용하였다. 연구참여자는 부모 이혼 후 재혼(동거)가정의 20대 자녀 4명이다. 자료 분석 결과, 자녀들이 계부모에게 아버지/어머니라 부르기 주저하는 이유는 '친부모가 있는데 왜 그분을 아버지/어머니라 불러야 하나요?', '아버지/어머니 없이 살아왔는데, 이제 와서 왜 필요하나요?', '그 분이 편하지 않아서 아버지/어머니라 부르지 않아요!'로 나타났다. 이러한 연구결과를 바탕으로 이혼 후 재혼(동거)가정 자녀의 계부모에 대한 호칭을 둘러싼 갈등 중재를 위한 상담의 지침을 제공하였다.

O presente trabalho pretende explorar a relação entre a língua nacional e a construção da idenidade nacional no Brasil, materializando os enunciados da "Casa-grande & Senzala" de Gilberto Freyre e os discursos cruzados entre Freyre e romancistas. Atualmente, o português brasileiro é uma manifestação mais extensa e mais profunda da alma multiforme da nacionalidade brasileira como a língua é um tópico essencial no processo de constituição da nacionalidade, ao lado da geografia, da história e da étnia. Junto com o português brasileiro, como o idioma oficial do Brasil, tradições, ideias nacionais se difundiam por todos os habitantes dessa comunidade imaginária. Ao invés dos temas clássicos(como a mestiçagem e a história da vida privada) de Gilberto Freyre, neste trabalho, discutimos as interpretações que Gilberto Freyre fez pelo prisma do luso-tropicalismo sobre a língua e a identidade nacional no Brasil, considerando o cruzamento da Casa-grande e da Senzala representadas na estrutura das obras dos romancistas brasileiros.

본 연구는 수달의 배설물에 근거해 한국 수달의 서식지 분포 및 그 패턴을 유추하기 위하여 수행되었다. 본 연구에서 분포 조사에 사용한 총 750개의 조사 격자 (13.75X11\;km) 중 34%에 이르는 255개의 구획에서 수달의 배설물이 존재한다는 것을 확인하였다. 수달 배설물의 지역적 분포 빈도는 경상북도(49.62%), 강원도 (49.56%), 충청북도 (41.67%), 경상남도 (38.00%), 전라북도 (37.93%), 전라남도 (24.24%), 충청남도 (20.29%), 경기도(7.36%)순이었다. 수달의 배설물이 발견된 대부분 지역에서 아주 적은 수(평균 1.7 spraints/sprainting site)의 배설물만을 확인하였으므로 지역별 개체군의 크기는 크지 않은 것으로 추정된다. 수달의 배설물에 근거해 유추한 수달 서식지의 분포 패턴은 한국에 서식하는 수달의 보전 및 관리를 위한 기초 생태자료로써 중요한 기여를 할 것으로 사료된다.

In this study, we are going to compare the chemical composition of the precipitation that falls in the Dangjin and Anmyon-do areas by analyzing the water soluble components (anion and cation). We also examined the effects of seasonal change and regional difference in those data sets. The [$NO_3\;^- \;+\;SO_4\;^{2-}$] at 49.2${\mu}$eq/l is 67% of the total anion of 73.1${\mu}$eq/l, while that of [$NH_4\;^+\;+\;Ca^{2+}$] at 37.7${\mu}$eq/l is 62% of the cation in Dangjin area. Also, the [$NO_3\;^-\;+\;SO_4\;^{2-}$] concentration of 151.8 (${\mu}$eq/l) is 62% for the total anion of 143.5 (${\mu}$eq/l), and the [$NH_4\;^+\;+\;Ca^{2+}$] concentration of 119.7 (${\mu}$eq/l) is 47% for the cation of 254.3 (${\mu}$eq/l) in Anmyon-do area. The ion composition ratio is shown for the order by 22% of $SO_4\;^{2-}$, 20.8% of $NH_4\;^+$ and 15.4% of $Cl^-$ that is the sum of 58.7% for the total ion composition in Dangjin area, and is the order by 33.8% of $NH_4\;^+$, 16.3% of $SO_4\;^{2-}$ and 11.1% of $Cl^-$ in Anmyon-do area. Furthermore, We predicted that even areas which were previously clean will get acid rain if there is large scale construction there or nearby.

This study was conducted to identify and compare the stressors and coping behaviors of high school students who experienced suicidal ideation vs those who do not. Method: The data were collected from 1,441 high school students living in the middle region of Korea. Researchers collected the data using Adolescent Stress Inventory and Adolescent Coping questionnare from February to May of 1999. Data were analyzed using X2, T-test. Result: A significant proportion (31.9%) of subjects had thought about suicide during the past 6 months, 297 girls (35.3%) and 163 boys (27.2%). Major stressors of subjects who experienced suicidal ideation were academic problems, conflicts between family members, and changes in sleeping or eating patterns. Conflicts with family members contributed to have suicidal ideation. There was no significant difference in helpful coping behaviors between the two groups. The group who experienced suicidal ideation had lower scores and fewer coping behaviors. Boys perceived more stressors and had fewer helpful coping behaviors than girls. Conclusion: It is necessary to develope school-based suicide prevention programs. Our findings suggest that the program should focus on problems related to studying and conflicts within the family.

The study was carried out to evaluate the affect of proton beam radiation on production of bulbil and tuber including change of endogenous gibberellins, of Dioscorea opposita Thunb. The yield of bulbils and tubers from non- and irradiated D. opposita Thunb at doses of 5, 10, 15 and 20 Gy were determined. Endogenous gibberellins were also quantified by GC/MS analysis. D. opposita tubers irradiated at 15 Gy produced higher bulbil production than non-irradiated plants. Enlarged bulbil (above size diameter 4 mm) was significantly increased at 15 Gy. Bioactive endogenous $GA_4$ was dominant in bulbils and tubers irradiated with proton beam rather than $GA_1$. Major gibberellins biosynthetic pathways in bulbils and tubers of D. opposita plants were non C-13 hydroxylation route. From the results of this study, 15 Gy proton beam radiation was suggested as an optimal dose that can produce high amounts of bulbil for mass production of D. opposita plant.
