Molecular chaperone의 발견은 생명과학자들에게 살아있는 세포 내에서 어떻게 생체활성단백질이 만들어지고 유지되는지에 대한 자극과 함께 그것을 증명하기 위한 실험동기를 부여하였다. 초기에는 Molecular chaperone이 nucleosomes의 assembly에 관여하는 단백질을 설명하기 위하여 사용되었으나, 지금은 기본적인 세포생리기능의 하나인 단백질의 folding과 assembly를 돕는 assistant protein으로 주로 사용된다. 단백질합성 뿐만 아니라 단백질수송, oligomeric structure의 assembly와 disassembly, heat shock을 포함한 각종 내, 외부스트래스에 의해서 변성된 단백질의 세로내분화와 회복에도 Molecular chaperone이 관여하고 있다. 그러나 아직까지는 Molecular chaperone들의 3차구조와 그들간의 상호작용에 관한 정보가 부족하여 크게 진전되지 못하고 있지만, 많은 연구자에 의한 정보축적으로 인하여 빠른 시일 내에 Molecular chaperone에 세포내역할이 분명하게밝혀질 것이다.

Living in the Information Age, schools and teachers are expected to utilize new information technology in education to make teaching more effective. In Japan, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) has been strongly implementing policies to promote information education (IE) in schools since 1988. According to a survey in 2005 (Japan MEXT, 2005), 100% of high schools in Japan at present have computers and the Internet connections. However, videoconferencing systems have only been introduced only in a small number of schools. This paper is the result of a pilot research to see the effects of using a videoconferencing system in a Japanese high school. The purpose of the research was to clarify the effects of introducing videoconferencing system in a Japanese high school and of utilizing it for conferences with other schools abroad on the studies of global issues. The target students were in the 12th Grade in the year 2006. The counterpart school was an Australian high school in Sydney and the conferences were held in English. International discussions on global warming were conducted between the Japanese and Australian students. Affective competence and cognitive competence were measured using questionnaires and worksheets given to students both before and after the videoconferences. The results showed that both cognitive and affective competences rose after each videoconference. Not only the students who actively participated in the conference but also those who were in the audience showed positive effects. In the field of international cooperation on global issues, especially, the effects were large. These results suggest that in order to teach global issues in which international effort and cooperation are needed, direct contacts with foreign students are effective in increasing student cognitive and affective competences. On the other hand, as English was the main communication tool in the conferences, Japanese students faced a certain difficulty in communication. Also, teachers, especially English teachers, were required to make great efforts to assist students in preparing for the conferences. The effectiveness of an international videoconference depends largely on students' English skills and teachers' efforts.

간경변 및간암 환자의 증가로 간이식술의 필요성이 점점 증가되고 있고, 특히 공여자의 생체 간이식은 간이식술의 주된 분야를 차지하고 있으며 간이식 수술 전 공여자에서 간체적의 정확한 측정은 수술 후 공여자와 수여자의 간기능을 예측하는데 있어 중요한 자료가 되며, 성공적인 수술과 환자의 예후에 밀접한 영향을 미친다. 그러나 현재 환자의 간체적을 구하는 과정은 환자의 모든 CT 영상위의 간을 수작업을 통해 영상분할한 후에 3차원 간체적을 구하고 있으며 많은 시간과 노력이 필요한 작업이다. 이러한 문제를 해결하기 위해서 본 논문에서는 자동으로 간과 비장을 문턱값처리, 형태학적 영상처리, 3차원 영역확장법등의 기법을 이용하여 분할하는 알고리즘을 개발하여 체적을 구하는 시간을 단축하였다. 이러한 알고리즘의 정확성을 평가하기 위해서 동물의 실제 간과 비장을 팬텀으로 제작하여 실제 측정한 체적과 알고리즘으로 분할된 영상의 결과를 비교 평가하였다. 문턱치값의 설정에 따라 다른 결과를 보이는 특성이 있지만 자동으로 문턱치를 결정했을 때 비장과 간의 체적측정 오차는 9.27%, -4.52%이었으며, 수동으로 문턱치를 결정했을 때 최소 오차가 각각 0.2%, 0.17%의 결과를 보였다. 이러한 팬텀 연구를 통해 자동 분할 알고리즘으로 얻은 체적의 결과가 정확성과 재현성을 보여주어 추후 간체적을 구하는 보조수단으로 활용될 수 있을 것이라 예상된다.

한국은 빠르게 고령화사회로 접어들고 있다. 이러한 시점에서 본 연구의 목적은 예비고령자들의 현 주거지의 외부환경 이용실태를 조사하고, 고령자 친화형 외부공간에 주요한 요소들을 파악하여 이들의 평가를 통해 고령자의 건강한 생활을 위한 환경요소를 파악하여 개선점을 제시하는데 있다. 연구 방법으로서 먼저 기존 선례와 관련연구의 조사를 통한 이론적 토대를 마련하고, 실증연구로서 대전에 거주하고 있는 준고령자 이상 주민의 외부환경 이용실태와 만족도에 대해 설문조사를 병행하였다. 본 연구의 결과로서 전반적으로 현 거주지의 외부환경이 큰 문제가 없이 중간 수준의 평가를 받고 있었지만, 평가요소들중 비교적 저평가된 요소들은 고령자 친화형 공간요소로 개선이 필요되어져야 할 것이다. 첫째, 산책하기 위해서 '산책길의 이용'이 가장 높았고, 한번에 1~2시간동안 외부에 머무르며, 주차된 차량이 많음이 가장 불편한 사항이었다. 둘째, 외부환경은 '보통'으로 평가되었으며, '사회성'이 기장 낮게 평가되었다. 셋째, '카트/휠체어 이용편리성', '조명에 의한 야간 식별성', '야간의 안내판 식별성'. '나무 화초 쾌적성'의 4 개 항목에서 남자가 여자보다 불만족하고 있었다. 66세 이상의 응답자들이 '바닥의 미끄러움', '계단난간', '야간의 안내판 식별성', '단지배치의 방향성' 항목에서 더 불만족하고 있었으며, '바닥 미끄러움', '야간의 안내판 식별성'의 두 개 항목에서는 80대 이상의 응답자들이 더 불만족하고 있었다. 넷째, 현 거주지 유형에 따른 평가는 22개 중 20개 항목에서 유의미한 차이가 나타나는 바, 아파트 거주자의 평가가 더 높게 나왔다. 전반적으로 현거주지 주변환경에 있어 고령자들의 입장에서 크게 문제로 대두된 것은 없다고 평가되었다. 그러나 향후 10년 내에 고령화가 더욱 진행된다고 가정할 때, 기술통계에서 낮은 점수를 받은 항목과 80세 이상의 고령자들에게 특히 불편을 야기하고 있는 낮은 평가항목에 대하여 주거환경 개선이 우선적으로 요구된다.

This paper reviews battering, sexual violence and divorce experienced among women. There three problems have negative influence on health status in women and are further developed to social problems such as family dissolution. The victims of the problems may manifest physical injury, emotional difficulties and social withdrawl, while their children may show problems caused by lack of parental caring and by resembling abusive behaviors of their parents. Hence, nurses need to pay attention to batting, sexual violence, and divorce and to develop relevant nursing interventions for them. Some strategies of dealing with those problems are presented in the following. First, we have to eliminate sexism prevailing in out society. Our society is assigning inequal and asymmetrical gender role. Mass media should inspire equality between genders and show a healthy model of family and community. Second, social system and laws should be changed through collective efforts. Those living conditions of women cannot be changed by the effort of women themselves only. We all need to work for establishing and changing the law, so that those women in suffering can obtain immediate and adequate protection. Third, social support system of consulting and referring women's problems should be established. Such support system as hot line, shelter and counseling clinics would help women in crisis. Fourth, job training and arrangement should be available to women who are divorced. Fifth, there should be self-help group for those women in suffering. Self-help group would help those women in sharing their problems and feelings and in establishing coping strategies. Nurses, as the largest group among health professionals, are sensitive and respond to health needs of clients and have an effect on managing women's health. However, we nurses have not been ready for dealing with problems of women, although most of us are women. we not need to change our perspective of women's health problems from a traditional medical perspective to feministic one. Accordingly, nurses need to develop realistic way of caring those women in suffering and to assist them in making decisions for their lives by themselves.

The purpose of school lunch service programs (SLPs) is to provide school children with nutritious meals each day, to assist them in improving their mental and physical development, to make them understand the basic knowledge needed for healthy daily living throughout their lives with sound nutritional habits, and further, to enhance the national health status as well as the individual. The major purpose of this study is to describe the history and current status and promotional plans in Korea's SLSPs to improve the nation's health status. The major findings of this study are as follow: 1) The progression of the SLSPs can be devided into four major periods: Relief (1953-1972), Self-supportive (1973-1977), System-establishment (1973-1983), System-development(1984- ). 2) As result of the implementation of SLSPs in Korea, many positive effects have been found in school education, notably in the field of physical growth, social development and personality cultivation. 3) This study deals with a more detailed assessment with regard to the effects of the program on school education activities and the improvement of nutritional habits in the family. Although it is limited and not yet complete, the program implementation has contributed to the improvement in children's food-intake habits, understanding of food, and manners, and increased sanitary consciousness. It has also affected of parent's concerns and attitudes towards the improvement of daily meals as well as national eating patterns, and eventually provided motivation for increased farm production of nutritious food stuffs and reasonable food consumption. 4) The SLSPs does have its stare of problem such as an unsatisfactory budget, lack of understanding of the program by school personnel and parents. However, there is no doubt that the SLSPs should be carried out effectively for better health, and especially for the growth and development of the children. Finally, the problems and promotive Plans of the SLSPs can be approached by aspects of the administrative, financial and operational systems. These system have to coordinate with relevant authorities to expand participation in the program for the successful implementation of the SLSPs. The eventual objective this study is to propose ways and means for mobilizing every available element in the effort to attain the goals of educating and training healthy and competent personnel manpower, stabilizing the demand and supply of food and the ensuring adequate coordination of national food production and consumption.

There has been a dramatic increase in public awareness regarding dementia during recent years. However, dementia remains a family affair and patients do not receive adequate care in Korea. This study aims to assist patients and their caregivers by establishing Home and Community based Long-Term Care in a city. The data collected for analysis include five main categories: dementia prevalence, limitations of daily activities of patients, burden of caregivers, the services that patient's family want to utilize, the resources that handle dementia in the community. Major findings can be summarized as follows: 1)The prevalence rate of dementia for elderly people is 13.1 per 100 persons. Alzheimer's disease amount to 38.9% of dementia patients and vascular dementia account for 36.7% of them 2)Eight out of ten patients have mild dementia. Almost all patients have normal ADL. IADL, however, shows different picture. In every items of IADL, about 60% of patients reveals some limitations. 3)The proportion of patients who had medical diagnosis is as low as 20%. Families of patients think dementia as normal aging process and medical doctors in the community do not give special concern to dementia patients. 4)Caregivers does not have proper social support. They suffer from long care time, experience large obstacles in respect of health, daily living, and social activity. 5)Health center and Community welfare center have launched some programs-consultation, home-visiting nursing, day care center, voluntary force mobilization and so on-for dementia patients. But they do not perform expected roles and functions because of lack of skilled personnels and inadequate coordination of relevant organizations for dementia care. 6)Families of dementia patients prefer home helper and home-visiting nurse to hospitalization. For the future, however, demand for institution-based long-term services will increase. We develope community dementia care model based on above findings as follows: 1)Health center execute community cardiovascular control program for the prevention of vascular dementia. 2)Refer to epidemiologic characteristics of patients and preference of family, the most urgent task for dementia care in this city is to expand and organize Home and Community based Long-Term Care. 3)For the continuous and comprehensive care, care plan for a patient must be prepared. Case management team should be builded to prepare this plan and coordinate relevant resources. 4)Special long-term care unit for dementia will be needed in a near future. This unit should have multiple functions, such as day-care center, short stay facility, training center for relevant personnels, besides long-term nursing home considering effective care of dementia and efficient operation of the facility. 5)Voluntary workers deserve their due efforts. Incentive mechanisms must be developed to activate voluntary activities.

The primary purpose of this research paper is to study the nutrition intake status of high school students and their physical growth and development. Further, it made an attempt to find and define nutritional problems and assist in their growth and development through proper nutritional management. One hundred students in both sexes, first year grade in senior high school were provided with questionnaires. For six days the respondents filled out the questionnaires. They were asked to keep record of what they ate each meal. Their nutritional intake were analyzed in accordance with what they ate. Findings, conducted on percentage, CR test, t test, and F test, were as follows: 1. For the living circumstance a) Average numbers of brother and sister in sampled family were four. b) Seventy to eighty percent of the students were brought up by mother's milk at their infants and approximately 40% of students were weaned at the age of 7 to 18 months. c) Fifty percent of the respondents revealed irregulity in their meal time. d) Monthly average expenditure for daily food reached $20{\sim}40%$ out of total income. e) The most favorite foods reflect as follows: The most favorite main dish is boiled rice and side dish beaf. Fruits. juice, milk, ice cream are more popular snack among whole students. 2. Nutrition survey a) Calory sad nutrients were found to be below the recommended level, especially in calcium, vitamins A, $B_2$ and C. b) The total calory intake were composed of 73% from carbohydrate, 14% from protein and 13% from fat in the case of boys. The girls were 65%, 14%, 21% respectively. c) Both boys and girls in their animal protein intake averaged about 33% out of total protein intake. d) Meat consumption of the majority respondents were proportionate in $10{\sim}20%$ in their total food consumption. 3. The result of statistical analysis were as follows: a) Statistical significant differences in the relationship between the calory intake and physical growth index were observed at the level of p<0.05. b) Statistical significant differences in the relationship between the protein intake and physical growth index were observed at the level of p<0.05. c) Statistical significant differences in the relationship between meal time and physical growth index were observed at the level of 0.02<0.05. d) No statistical significant differences in the relationship among calory, protein intake and school records as well as intelligence were found. The experiment indicated that there is a direct relationship between nutrition and the physical growth and development, whereas There seems to be an indirect relationship between nutrition and intelligence.
