This study is designed to shed light on the current status of school health education in Korea and identify its problems. The findings of this study among other things pointed out that health education should be awarded the status on an independent subject in a bid to activate school health education and cope with its problems. Thus for efforts focused on the needs for establishing health education as an independent course as well as for enhancing the awareness of its importance. At this stage further efforts are needed to develop in-depth discussions and add greater variety to the curriculum. Firstly efforts should be made to recognize the health status of students at all levels, i.d., from kindergarten through university. Particulary at this stage when the entire society is going through changes in the types of health problems and disease pattern, the outcome of analyses on the types of health problems and health-related behavior can be used as basic data for framing the contents of school health education. Secondly more active efforts are required to single out the contents of health education and develop health education curricula assessment based on the findings of surveys on that of health education needs. Thirdly the development of school health education curriculum should be accompanied by that of more effective educational methods and materials. In particular, further efforts should be made to develop educational methods designed to make wider use of audio-visual equipments or apply behavior modification techniques so that school health education will be adapted to changed educational environment and the characteristics of health education. Fourthly and most importantly the training and production competent health education teachers is needed. This should be preceded by the amendment of relevant laws and administrative systems.

Agriculture and forest are basis for livelihood in Nepal while both sectors constitute around 40 percent of the national product and over two-thirds of the economically active population is dependent on agriculture. However, radical changes in land use, depletion in crops production and food availability are major threats due to loss of soil fertilityand severe environmental degradation. In this study, we used time series data from 1986/87 to 2005/06 about food crop production and population published by Government of Nepal, Ministry of Agriculture and Cooperatives and Central Bureau of Statistics. Descriptive statistics and ArcGIS were used to assess and map the food security status of Nepalese Terai based on the local food demand and supply system. Food supply to demand ratio(FSDR) was the main idea of assessment. Our results showed that out of 20 districts, only 8 districts were categorised under secured food districts whereas 5 districts were still under food unsecured situation. The analysis further revealed that 7 districts had faced food deficit more than 8-16 times during the last 20 year periods. Data further showed that there was surplus food supply relative to the requirements dictated by FSDR. However, the average FSDR was less than 1.2(less than 20% surplus) exploring fact that most of the districts were not producing sufficient food to cope up the food shock and after 1995 it was relatively stagnant. Our prediction reveals that food supply in Terai even in the future would remain at almost the same level as now, and there will not more than 16-17% surplus by 2021 considering medium vibrant population growth. The findings thus, indicate that Terai may not be a food secure region in the future, even though the region is considered as a food storage house of Nepal. In addition, this paper suggests ways to make future comprehensive case studies more widely comparable in Terai, Nepal.

원전 작업자 피폭관리와 안전성 평가 및 최종적으로 처분허가를 위하여 폐기물 내의 핵종 및 농도를 파악하여야만 한다. 이온교환 수지 및 필터는 그 부피는 작으나 원전 운전중 발생하는 폐기물 내 방사능의 대부분을 차지하고 있다. 본 연구의 목적은 냉각수 정화 계통내의 수지 및 필터 내에 누적되어 있는 방사성 핵종의 양을 예측할 수 있는 방법을 개발하는 것이다. 핵종누적량을 계산하기 위하여 평균제염계수 대신 순간제염계수를 사용하였으며 포트란언어를 사용하여 프로그램을 작성하여 누적량을 계산하였다. 본 예측기법의 검증을 위하여 미국 Rancho-Seco 발전소의 측정자료를 이용하였으며 실험을 통한 계측자료를 검증에 이용하였다. 순간제염계수를 이용한 본 방법의 계산이 평균제염계수를 이용한 것보다 오차가 작았다. 이 방법을 실제 적용하기 위해서는 운전지침에 의하여 주기적으로 계측한 제염제수와 핵종농도 자료만으로도 핵종누적량 계산이 가능하다. 그러나, 특히 발전소 운전상황이 급격하게 변할 때에는, 정확한 누적량 평가를 위하여 제염계수 및 방사성 핵종농도의 측정주기가 짧아져야 한다.

Oral and maxillofacial infection is a common complication in patients undergoing chemotherapy. The treatment of oral diseases in such patients differs from that administered to healthy patients. This paper reports a case of acute osteomyelitis of odontogenic origin following a recent chemotherapy session. The patient's condition was life-threatening because of neutropenic fever and sepsis that developed during the inpatient supportive care. However, the patient showed prompt recovery within 40 days following the use of appropriate antibiotics and routine dressing, without the requirement for surgical treatment, except tooth extraction. As seen in this case, patients undergoing chemotherapy are more susceptible to rapid progression of infections in the oral and maxillofacial areas. Therefore, accurate diagnosis through prompt clinical and radiological examination, identification of the extent of infection, and assessment of the patient's immune system are crucial for favorable outcomes. It is also necessary to eliminate the source of infection through appropriate administration of antibiotics. In particular, a broad-spectrum antibiotic with anti-pneumococcal activity is essential. Proper antibiotic administration and wound dressing are essential for infection control. Furthermore, close consultation with a hemato-oncologist is necessary for effective infection management based on the professional evaluation of patients' immune mechanisms.

This study used a qualitative research method to comprehensively deal with child care training in depth with the following content: the goals of child care teachers preparing for practical training; how they perform and feel about their roles throughout the training period as child care teachers; and their evaluation after the training period. A total of 10 people participated in the research and the training activities of child care teachers were qualitatively explored based on the results. The research findings are as follows. First, child care teachers have expectations for prospective teachers and take time for self-evaluation while preparing for teaching. Also, child care teachers set a goal of helping prospective teachers develop into outstanding teachers and have expectations for it. Second, child care teachers evaluate prospective teachers by treating them as colleagues while teaching them. Furthermore, child care teachers consider themselves as educators who train and produce child care professionals. Prospective teachers define their roles as assistants and learners in the actual educational scene. In addition, child care teachers feel a sense of pride by performing as hands-on training teachers. At the same time, they reflect on themselves by evaluating their duties as educators in their relationships with prospective teachers. Third, child care teachers suggested the need for changing the training system for themselves and prospective teachers after training. In addition, they argued that the gaps between school education and the actual educational scene should be reduced through solid training for acquiring new knowledge and information in both places in accordance with the rapidly-changing child care environment. Finally, the suggested the necessity of establishing a standard training curriculum and educational programs within their institution.

Purpose: To analyze the home care services provided to the elderly aged 65 and older by a hospital-based home care agencies and to investigate the effects of long-term care insurance for the elderly. Method: The subjects were the home care service recipients aged 65 and older in 172 hospital-based, home care agencies registered in Health Insurance Review & Assessment Service in January, 2007. The data were collected using a questionnaire from March 16 to April 15, 2007. The questionnaire return rate was 43.8%. Result: The hospital-based home care agencies were able to visit 66.5% of the national administrative districts. Of the home care service recipients, over 50% were 65 years old and older. About 43% of the agencies reported that over 50% of their patients would be subject to the long-term care insurance. They expressed concern that home care services would be withdrawn once the insurance system is initiated. Conclusion: This study suggests that hospital-based home care agencies need to manage home care services with long-term care insurance. It also recommends developing guidelines for the use of services and referrals.

The effect of climate change on urban woody plants remains difficult to predict in urban areas. Depending on its tolerances, a plant species may stay and survive or stay with slowly declining remnant populations under a changing climate. To predict those vulnerabilities on urban woody plants, this study suggests a basic bioclimatic envelop model of heat requirements, cold tolerance, chilling requirements and moisture requirements that are well documented as the 'climatic niche'. Each component of the 'climatic niche' is measured by the warmth index, the absolute minimum temperature, the number of chilling weeks and the water balance. Regarding the utility of the developed model, the selected urban plant's present probabilities are suggested in the future climate of Seoul. Both Korea and Japan's thermal thresholds are considered for a plant's optimal climatic niche. By considering the thermal thresholds of these two regions for the same species, the different responses observed will reflect the plant's 'hardening' process in a rising climate. The model illustrated that the subpolar plants Taxus cuspidata and Ulmus davidiana var. japonica are predicted to have low suitability in Seoul. The temperate plants Zelkova serrata and Pinus densiflora, which have a broad climatic niche, exhibited the highest present probability in the future. The subtropical plants Camellia japonica and Castanopsis cuspidata var. sieboldii may exhibit a modest growth pattern in the late 21C's future climatic period when an appropriate frost management scheme is offered. The model can be used to hypothesize how urban ecosystems could change over time. Moreover, the developed model can be used to establish selection guidelines for urban plants with high levels of climatic adaptability.
