The purpose of this study was to identify housing attributes that make residents feel 'at home' in ALFs in Southwest Virginia. For this purpose, residents' needs, experiences, and opinions of the physical environment, the social environment and the organizational environments such as policies and programs of ALFs were identified. As a multi-case study, five ALFs in Southwest Virginia were studied using constant comparative methods of data analysis. In addition to face-to-face interviews with 25 residents and 5 administrators of five ALFs, observations were conducted with personal journal. Each facility was designed to be a single-family house or multi-family dwelling in outside appearance. Most of the respondents were satisfied with their current dwelling as a 'home' in terms of homelike attributes such as 'autonomy/ privacy', personalization,' safety and security,' services and care,' independence,' social interaction/friendship,' family support,' and 'rules and regulations.' In spite of high satisfaction with the facility, however, many people did not think of their current dwelling as a real 'home'. As the biggest difference between living in their own homes and living in the ALF, people feinted out a lack of independence and social interaction. Residents of ALFs may have reordered their priorities in their current life situation so that safety, security, and caie were more important to them than fooling "at home."

녹용이 동물체에 미치는 영향을 조사하기 위한 일환으로 녹용 침출액을 집토끼에 주사한 후 여기에서 여섯개의 조직(골격근, 간, 신장, 부신, 비장, 심장근)을 선택 적출하여 disc-gel electrophoresis로 수용성 단백 분획상을 비교 하여 보았다. 대조군과 5일간 주사한 군에서 간, 신장, 부신, 비장에서는 서로 동일한 영동분획상이 나타났으나 골격근과 심장근에서는 대조군보다 실험군(5일간과 15일간 녹용침출액을 주사한 군)의 영동대에서 하나의 영동대가 더 나타났다. 한편 15일간 주사한 실험군과 5일간 주사한 실험군 사이에서는 단백분 획상의 차이점이 없음을 알았다. 이와 같은 변화는 녹용의 어떤 특수성분이 주로 근육형 조직에서만 백질을 합성하는 기작에 영향을 끼친 것이 아닌가 사려된다.

최근 원격 제어 시스템은 언제 어디서나 인터넷에 연결되어 있으면 회사나 학교 등 원격지에 위치한 컴퓨터에 접속하여 작업을 수행할 수 있게 해준다. 원격지의 컴퓨터를 어디서나 사용할 수 있게끔 해주기 때문에 재택 근무 등을 이유로 집과 학교와 같은 장소에서 동일한 컴퓨팅 환경을 구성해야 하는 불편함을 없애준다. 그러나 최근 다양한 네트워크 공격과 해킹의 시도로 인해서 회사나 학교에서는 방화벽을 사용하여 외부로부터의 허용 되지 않은 패킷을 차단하기 때문에 이러한 이점을 지닌 원격제어 시스템을 사용하지 못하는 경우가 많다. 이에 외부에서 방화벽 내의 시스템을 접근할 수 있도록 역방향 원격제어 방법을 제안하고 오픈소스인 VNC를 기반으로 원격제어 시스템을 개발하였다.

In this paper, the causal relationships in Onward are compared and contrasted with the ones in Up. The characters in Up purposefully move to action for the given cause. The residents there accept the surreal beings as normal. Thus, the viewers understand such surreal beings in the scene as part of the fantasy world of Up. The protagonists in Onward also have purpose for the actions they take. For achieving their goal, they choose problem solving method from the magical world. However, there is no causal relationship between reality and their world. Thus, it fails to persuade its viewers.

In a PWR rod cluster control assembly(RCCA) for shutdown is released upon action of control rod drive mechanism and falls down through the guide thimble by its weight. Drop time and impact velocity of the RCCA are two key parameters with respect to reactivity insertion time and the mechanical integrity of fuel assembly. Therefore, the precise control of drop time and impact velocity is prerequisite to modifying the existing design features of the RCCA and guide thimble or newly designing them. During its falling down into the core, the RCCA is retarded by various forces acting on it such as fluid resistance caused by the RCCA movement, buoyance and mechanical friction caused by contacting inner surface of the guide thimble, etc. However, complicated coupling of the various forces makes it difficult to derive an analytical dynamic equation for the drop time and impact velocity. This paper deals with the development of a computer program containing an analytical dynamic equation applicable to the Korean Fuel Assembly(KOFA). The computer program is benchmarked with an available single control rod drop tests. Since the predicted values are in good agreement with the test results, the computer program developed in this paper can be employed to modify the exiting design features of the RCCA and guide thimble and to develope their new design features for advanced nuclear reactors.

The Manual for Buddhist Rituals (1935) is the manual of Buddhist rituals which has a pivotal position in terms of the modernization of Korean Buddhist rituals. The text has been established through the contents and systems of the two texts, The Manual for Practising Rituals (作法龜鑑, 1827) and the Compulsory Manual for Buddhists (佛子必覽, 1931). These three manuals include the examples for practising the Manuals. The analysis of the examples for the practices of the three texts is as follows: The Manual for Practising Rituals tries to include the Sounds of the Music for the Buddhist Rituals through the Four Sounds (四聲) and the Twin words (儷語); the marks of the sounds are excluded after the compulsory Manual for Buddhists. The Manual for Buddhist Rituals has replaced the rituals for repentance (三寶通請) with the rituals for revering (四聖禮): and this text has made it easier that people participate in Buddhist rituals with the text which is written in bilingual format in Korean and Classic Chinese. The text has been popularized through above-mentioned changes against the previous two texts but it has ended up excluding the practices for the music of Korean Buddhism such as the music for Buddhist rituals (梵唄) and reciting the name of Buddhas (念佛).

The major purposes of this study are to examine the effects of portfolio assessment on elementary school student's science knowledge, inquiry ability, science attitudes and to investigate students' perceptions on portfolio assessment. Control group consists of 45 fourth-graders at M-Elementary school located at Miwon, Chongwon-gun, Chung-buk and experimental group 36 fourth-graders of G-Elementary school located in Daejeon-si. The inventories of scientific knowledge I, inquiry ability, and science attitudes were administered to both groups as a pre-test. The experimental group was given portfolio assessment instruction and control group traditional instruction for about six weeks. Inventories about scientific knowledge 2, inquiry ability, and science attitudes were administered to both groups as a post-test. A questionnaire on the perception on portfolio assessment was given to experimental group after the treatment. The results were statistically analyzed with SPSS. Control group showed higher score on scientific knowledge than that of experimental group (p<0.5). No statistically meaningful difference was identified in inquiry ability and scientific attitude. More in-depth analysis revealed that scientific attitudes were improved statistically meaningfully by portfolio assessment. The students' perceptions on portfolio assessment is very positive. Students have positive responses on interests in portfolio assessment, feelings of involvement in learning, self-regulated learning, higher levels of thinking, intentions of participation in portfolio assessment.

Purpose : It has been suggested that the exposure to aeroallergens during early infancy after birth is important in the subsequent development of sensitization and allergic diseases. In Korea, the level of house dust mites as one of the important aeroallergens is known to be the highest in autumn. The aim of this study was to test whether the distribution of month of birth bears a relationship to the presence of mite sensitization in children with respiratory allergy. Methods : Skin prick tests and methacholine provocation tests were performed on 1,327 patients with chronic respiratory symptoms who visited Seoul National University Children's Hospital from January 1995 to May 2002. An analysis of patients' month of birth distribution according to the presence of mite sensitization was performed. Results : Atopic subjects who had at least one positive skin test numbered 864(65.1%); and non-atopic subjects numbered 463(34.9%). Among atopic subjects, 787(59.3%) had positive skin tests to mites and 77(5.8%) had positive skin test only to minor allergens. A significantly greater than expected number of mite atopic subjects were born in the months between August and November(P=0.03), however, the birth month of non-atopic subjects didn't show a consistent seasonal preference. Asthma patients numbered 543(40.9%). Among these, atopic asthmatics numbered 421(77.5%) and non-atopic asthmatics, 122(22.5%). Dust-mite atopic asthmatics numbered 387(91.9%) out of 421 atopic asthmatics. Dust-mite atopic asthmatics were born significantly higher in the season lasting from August to November in comparison to non-atopic asthmatics(P=0.002). Conclusion : Month of birth seems to be related with sensitization to allergens. Our results show that August to November is the risk period for the development of mite sensitization in Korea.
