Purpose: This study was to identify the role of general hospice palliative nurse through job analysis (duties, task, and task elements). Methods: The sample consisted of 136 nurses or professors who were performing duties related to hospice care areas in Korea. A survey method was used, and the questionnaire included frequencies, criticality, and difficulties of task elements in job description by the DACUM method. Descriptive statistics were performed by using SPSS WIN 17.0. Results: The job description of general hospice palliative nurse was identified 8 duties, 36 tasks, and 137 task elements. As for the 8 duties, the average scores of frequency, criticality, and difficulty were 2.94, 3.66, and 2.80, respectively. The role of ‘pain assessment’ was the most important task element among frequency and criticality. The lowest score at the frequency and criticality were ‘manage public finance’ and ‘collect datum through diagnostic test & lab', respectively. Furthermore, the role of 'identify spiritual needs of patients and family' was the most difficult task, whereas the role of 'manage documents and information' was the least. Conclusion: In this study, we could recognize the reality of general hospice palliative nurse's performances. For general hospice palliative nurse, therefore, concrete practice guide lines of psychosocial and spiritual care, communication skills, and bereavement care with qualifying system are critically needed.

In this study, it is analyzed whether oil price plays a major role in the pricing return on Koran stock market and examined why the covariance risk between oil and return on stock is different in each industry. Firstly, this study explores whether the expected rate of return on stock is pricing due to global oil price factors as a function of risk premium by using a two-factor APT. Also, it is examined whether spill-over effects of oil price volatility affect the beta risk to oil price. Considering the asymmetry of oil price volatility, we use the GJR model. As a result, it shows that oil price is an independent pricing factor and oil price volatility transmits to stock return in only electricity and electrical equipment. Secondly, the two step-analyzing process is introduced to find why the covariance between oil price factor and stock return is different in each industry. The first step is to study whether beta risk exists in each industry by using two proxy variables like size and liquidity as control variables. The second step is to grasp the systematic relationship between the difference of liquidity and size and beta to oil price factor by using the panel-data model which can be analyzed efficiently using the cross-sectional data formed with time series. Through the analysis, we can argue that oil price factor is an independent pricing factor in only electricity and electrical equipment having the greatest market capitalization, and know that beta risk to oil price factor is a proxy of size in the other industries. According to the result of panel-data model, it is argued that the beta to oil price factor augments when market capitalization increases and this fact supports the first assertion. In conclusion, the expected rate of return of electricity and electrical equipment works as a function of risk premium to market portfolio and oil price, and the reason to make beta risk power differentiated in each industry attributes to the size.

The purpose of this study was to examine the change in the classes of beginning science teachers through the collaborative mentoring program that induce reflective thinking practice. Participants in this study were three mentor-teachers, two teachers in doctor's or master's course, one university professor, and three mentee-teachers who have less than four years of teaching experience. We collected data such as video recordings of the mentee-teachers' classroom teaching and transcription, lesson plans, recording of one-on-one mentoring and transcription, mentor and mentee's journals, and RTOP classroom teaching observation reports. RTOP was used for the analysis of classroom teaching and mentee-teachers' recognition and changes in their classes were found out through journals and one-on-one mentoring interview materials. According to mentee-teachers' recognition and changes in their classes during the mentoring program, they themselves recognized their teacher-centered teaching style, misconception, and lack of content knowledge. Furthermore, there were changes in the mentee-teachers' classroom teaching through their reflective practice and improvement. As a result of this study, the interactions with mentor-teachers through collaborative mentoring program stimulated mentee-teacher's reflections on their teaching. Therefore, these reflections led to their reflective practice that showed progressive changes in their teaching behavioral activities. The extent of these changes varied according to the mentee-teachers' individual disposition toward reflection and the issue of whether mentee-teachers' reflective practice was in accordance with priorities in motivational ZDP or not. Also based on the results of this study, the teachers' reflection was not all accompanied by reflective practice even if the beginning science teachers made some partial changes in reflective practice through reflection. It means that it is hard to lead reflective practice for mentee-teachers through mentoring in a short period of time. Therefore, we consider that a systematic and long-term mentoring program is necessary for beginning science teachers.

Farmers directly spread the livestock manure compost on their arable land as an organic fertilizer. However, there are some difficult problems to solve. first, we are unsure of whether the livestock manure compost can meet the nutritional demand of plant. Second, application of the current powered livestock manure compost to crop land is very difficult work due to heavy weight of compost and its powdered shape. For this reason, this study was carried out to develope high quality pelletized livestock manure compost. In pelletizing process with composted manure, the optimal water content for pelletizing was around 30$\sim$40%. When rice bran was mixed with 5% as a bonding agent on volume basis, the pelletizing effect was remarkably improved. On a dry matter basis, the contents of N and P of manure compost were 1.31%, and 0.58%, respectively. After pelletizing, the contents of compost pelleted were 1.37% and 0.54%, respectively. The same parameters of pelletized compost made by screw type Instrument were 1.37% and 0.53%, respectively. The other hand, N and P content of pelletized compost made by pellet mill type instrument were 1.06% and 0.18%, respectively.

In recent years, with the development of computers and electronics, electronics and communication technology in a growing and each part is dependent on the cross-referencing makes all electronic equipment is obsolete due to direct or indirect damage EMP. Korea and the impending standoff North Korea has a considerable level of technologies related to the EMP, EMP weapons you already have or in a few years, the development of EMP weapons will complete. North Korea launched a long-range missile and conducted a nuclear test on several occasions immediately after, when I saw the high-altitude nuclear blackmail has been strengthening the outright offensive nuclear EMP attacks at any time and practical significance for the EMP will need offensive skills would improve. At this point you can predict the damage situation of Korea's security reality that satisfy the need, more than anything else to build a protective system of the EMP. The scale of the damage that unforeseen but significant military damage and socio-economic damage and fatalities when I looked into the situation which started out as a satellite communications systems and equipment to attack military and security systems and transportation, finance, national emergency system, such as the damage elsewhere. In General, there is no direct casualties reported, but EMP medical devices that rely on lethal damage to people who can show up. In addition, the State power system failure due to a power supply interruption would not have thought the damage would bring State highly dependent on domestic power generation of nuclear plants is a serious nuclear power plant accident in the event of a blackout phenomenon can lead to the plant's internal problems should see a forecast. First of all, a special expert Committee of the EMP, the demand for protective facilities and equipment and conduct an investigation, he takes fits into your budget is under strict criteria by configuring the contractors should be sifting through. He then created the Agency for verification of performance EMP protection after you have verified the performance of maintenance, maintenance, safety and security management, design and construction company organized and systematic process Guard facilities or secret communications equipment and perfect for the EMP, such as protective equipment maneuver system should take.

This study was conducted to evaluate the effect of the application of green manure in the form of either green barley and Chinese milkvetch in reducing the amounts of N fertilizers and conventional fertilizers needed for paddy rice. Prior to rice transplanting, the green barley and Chinese milkvetch as a green manure produced respectively $668kg\;10a^{-1}$ and 3,492kg\;$10a^{-1}$ in fresh shoot weight basis. Calculated nitrogen content from harvested green manures was 3.9 and $17.8kg\;10a^{-1}$, respectively. Plant height and tiller number of rice increased when two kinds of green manure incorporated into soil. Above mentioned parameters also increased with increasing amounts of N fertilizers at both ear formation and heading stage of rice. Rice grain number was not affected by green manures treatment but increased when N fertilizers were applied. Although rice panicle and grain number increased with green manure treatments and fertilizer applications, whereas the percentage of ripened grain decreased. Chinese milkvetch with additional N fertilizer applications increased brown rice yield from 1 to 5% compared to rice yields in plots where non-green manure with the conventional amount of fertilizer application was applied. Rice treated with Chinese milkvetch and 30% of the conventional N fertilizer rate yielded the same as rice fertilized conventionally. During the rice growing season, $NH_4-N$ content of paddy soil was higher in green manures treatment than non-green manure one. Average $NH_4-N$ content in paddy soil drastically decreased after heading stage below $5.7mg\;kg^{-1}$ in non-green manure treated plots. While on the other, $NH_4-N$ content in soil slowly decreased in plots those were treated with green manures at harvesting stage, average $NH_4-N$ content was still greater than $5.5mg\;kg^{-1}$. Nitrogen content of rice shoot and brown rice seed was higher in green manure treatment.

This experiment was conducted to evaluate the dietary effects of multiple mixture of probiotics on laying performance and the faecal examination in laying hens (Hy-line Brown) at the early (21~40 wk) and middle (41~65 wk) laying term. Multiple probiotics were produced by developing products and the properties of microorganisms were examined for detecting of acid-resistance, bile salt-resistance and antibacterial activity against pathogenic enteric bacteria. Probiotics produced to the fermenting cultures of four selected organisms and soybean meal substrates by nine steps of NK proliferating system. The most microorganisms were shown higher resistance of acidity and bile salt. High antibacterial activities against Bacillus subtilis, Lactobacillus plantarum and Enterococcus faecium were observed, but was not against Saccharomyces cerevisiae. Total egg production of the treatment was significantly higher than control group but was not statistically different between 0.1% and 0.2% treatments (P>0.05). Average egg weight of the treatment in early laying term was also significantly higher than control but was not significantly different between 0.1% and 0.2% treatments (P>0.05). But the egg weight of the treatment in middle laying term was significantly higher than control and between 0.1% and 0.2% treatments (P>0.05). The mortality of 0.2% treatment was significantly lower than control (P<0.05), and 0.2% treatment in the early laying term was tended to decreased than 0.1% treatment and control. But there was not significantly between 0.1% and 0.2% treatments in middle laying term. In feed intake, 0.2% treatment in middle laying term was significantly increased than control and 0.1% treatment (P<0.05) but not in early laying term. In faecal examination, the total number of Lactobacillus of 0.1% treatment was significantly increased than control in whole laying term (P<0.05), but Coli form of the treatment was decreased than control in middle laying term. In conclusion, dietary long term supplementation of multiple probiotics improved performance of lay hens, egg weight and mortality drop by regulating enteric bacteria.

Objectives: This study aims to identify health status and health risks among female marriage immigrants to Korea and to provide a basis for public health strategies to address their health issues. Methods: The participants of the study were 3,069 immigrant wives. The health examination was conducted by the Korea Association of Health Promotion (KAHP) in 2008. The participants also completed self-administered questionnaires on demographic characteristics, health-related behaviors and mental health. Results: Patterns of immigrant women's health problems differed by age and country of origin. Behavior patterns also differed by their heritage, age, and years of residence in Korea. Generally Vietnamese women fell in lower ranges of disease prevalence and health risk factors in the participant group and Japanese women presented most healthy eating habits. Filipina women showed relatively high disease prevalence than any other group. Conclusion: Immigration to Korea by marriage is relatively a new phenomenon, thus continuing surveillance and research are needed to identify health risks, behavior patterns, and their relationships. Interventions and policies for the health of migrant wives, their children and families are required.

Purpose: This study was conducted to assess the association of metabolic syndrome and its components with glaucoma. Methods: We investigated the associations of metabolic syndrome and its components (abdominal obesity, impaired fasting glucose, high blood pressure, and dyslipidemia) with glaucoma using data from 19,162 adults aged 40 or above among the Korean National Health and Nutrition Examination Survey III (2005), IV (2007-9), V (2010). The logistic regression analysis was used for assessing those associations after adjusting demographic, lifestyle, and social economic status and for assessing the association of metabolic medication intakes with glaucoma risks. Results: After adjusting for age and sex, the risk of glaucoma was significantly higher in the subjects with impaired fasting glucose(Odds Ratio (95% confidence interval): 1.78 (1.25, 2.53)) and metabolic syndrome (1.45 (1.01, 2.08)) than subjects without those. These associations increased when additional adjusting for smoking, alcohol use, regular physical activity, income, education status(impaired fasting glucose: 1.89 (1.29, 2.77), metabolic syndrome: 1.52 (1.03, 2.25)). Glaucoma prevalence was borderline significantly increased according to the number of metabolic abnormalities(age and sex adjusted p for trend = 0.055). Use of antihypertensive medication was significantly associated with the risk of glaucoma. Conclusions: Metabolic syndrome and impaired fasting glucose were significantly associated with the increased glaucoma risk. Use of antihypertensive medication was also significantly associated with the increased glaucoma risk.

국내 보험 산업은 경제발전에 따라 많은 성장을 이루어왔으나 단체보험은 보험 회사의 외부적 또는 내부적 환경으로 인해 활성화가 미흡한 상황이다. 개인보험시장의 포화, 해외시장에서 단체보험의 지속적인 성장, 사회보험 민영화 논의, 방카슈랑스와 보험시장의 개방 등 급격한 변화를 겪고 있는 보험영업환경을 고려한다면 향후 확대될 기업복지시장에서의 성공적 역할수행을 위해서는 단체보험 영업과 지원시스템의 보완이 시급한 과제라고 할 수 있다. 특히 언더라이팅 기법은 단체보험의 핵심역량이며 회사의 경쟁력 강화와 사차익 안정화를 위해서는 단체보험 인수기법의 선진화가 필수요건이다. 단체보험은 대수의 법칙, 수지상등의 원칙 등 보험의 기본원리라는 측면에서는 개인보험과 다른 점이 없지만 하나의 계약을 통해 집단의 피보험자에게 보장을 제공하기 때문에 가지게 되는 역선택 축소, 비용절감, 기업에 의한 1차선택 등 몇 가지 특성들은 인수기법에서의 차이를 필요로 한다. 하지만 국내의 단체보험 언더라이팅은 기본개념조차 제대로 정립되어 있지 못한 초기단계로 단체보험의 특성을 제대로 반영할 수 있는 위험평가를 위해서는 선진기법의 도입이 절실하다. 첫째, 자유보장한도(FREE COVER LIMIT)의 도입이다. 자유보장한도는 단체에 대한 위험과 피보험자 개인의 위험을 구분하는 기준으로 자유보장한도내의 피보험자에 대해서는 고지나 의적 검사를 요구하지 않고 개인별 언더라이팅을 하지 않으며 거절체나 표준하체이더라도 자유보장한도 금액까지는 나머지 정상 피보험자들과 동일한 보장을 제공하는 것을 말한다. 이는 피보험자별 위험을 중심으로 심사하고 있는 현재의 국내 단체보험 인수방법에서 발생되는 고객측 불만과 심사의 비효율성을 개선할 수 있는 방안이다. 둘째, 단체별 특성에 따른 보험요율 차등화이다 단체는 산업의 종류, 피보험자의 직무, 지역적 위치, 크기(피보험자수), 성별구성비 등 여러 가지 특성들을 가지고 있으며 이런 특성들은 보장급부에 따라 발생위험에 영향을 미칠 수 있다. 하지만 현재 나이와 성별에 따라서 피보험자별로 정해지는 요율체계만으로는 이런 위험들을 적절하게 반영하지 못하고 단체별 형평성에도 문제가 생긴다. 따라서 정확한 data 구축을 통해 단체 특성별로 어떤 보장에 어느 정도로 위험 발생에 영향을 미치는지를 분석하여 보험요율을 차등부과 할 수 있는 체계를 갖추어야 한다. 셋째, 경험을 활용한 보험료 산정기법이다. 이것은 개인보험과 구분되는 가장 큰 단체보험만의 특성이라 할 수 있는데 해당 단체의 과거 경험 data 즉 청구로 인한 지급금액을 토대로 당해 계약 보험료를 결정하는 방법이다. 이를 위해서는 과거 경험 data가 얼마나 신뢰할 수 있는 지의 정도(신뢰도)를 측정하는 것이 필요하다. 과학적이고 효율적인 단체보험 인수를 위해서 경험율의 활용은 반드시 이루어져야 할 선결과제이다. 넷째, 관련규정의 정비가 필요하다 단체보험의 특성을 갖기 위해서는 가입가능한 피보험자들의 자격규정(eligibility), 활동적근무 조건(actively at work)이 요구되어야 하며 참여비율(가입비율)과 보장수준의 구성방법에 대해서도 가이드라인 설정을 통해 역선택을 최소화 할 수 있는 제도적 보완이 마련되어야 한다. 이런 선진인수기법의 도입과 함께 단체보험 언더라이터의 필요역량을 개발하고 향상시키는 노력도 병행되어야만 종합금융화, 대형화가 진전되면서 대경쟁의 구도로 바뀌고 있는 국내 보험시장에서의 경쟁력 확보가 가능할 것이다.
