In this paper, a program to analyze the proportional solenoid valve is developed with conventional FEM tool. To achieve the convenience and analysis accuracy, it is supposed that the solenoid valve is composed of some simple geometries, which are a triangle and a rectangle. This assumption make the modeling of valve simple. To check the feasibility of the developed code, a real example of a solenoid valve are analyzed and it is found that the code can calculated for the valve and the characteristic of a proportional valve is shown with graphs.

분석 결과 주제별 분석에서 經部에는 승려들이 처음 입문했을 때 필요한 전적으로 한자 학습서가 많이 소장되어 있으며, 史部에는 사찰의 事蹟이 많이 소장되어 있다. 子部의 석가류에는 看話禪과 관련된 전적을 비롯한 禪籍이 많이 소장되어 있었다. 또한 신앙, 의례와 관련된 전적도 많았다. 집부에는 승려와 유가의 문집이 많이 소장되어 있었다. 소장된 전적의 간행시기는 대부분이 17세기에서 20세기에 간행된 전적들이다. 귀중서에 해당되는 임란이전에 간행된 전적은 12종이었다. 간행지는 전국에 걸쳐 분포하고 있으며 중국에서 간행된 전적은 62종, 일본에서 간행된 전적이 3종이었다. 소장 전적의 간행처는 대부분이 사찰에서 간행된 전적이 많았다. 묵담유물관에 소장된 전적은 대부분이 17세기 이후에 간행된 불교전적으로 사찰에서 간행된 전적이 많이 소장되어 있었다. An analysis of the subjects of the books housed by the Mukdam Museum at the Yonghwasa Temple showed the following results. The religious part of books includes those needed for Buddhist monks at the beginning stage of their training, and those necessary for learning Chinese letters. The historical books contain records of events at temples. The books about great minds involve those about zen (thinking in serenity) including books about Buddha himself related to the thinking of topics while regarding the void. It also includes many books about faith and rituals. Referring to the time of the publication of the books, most of them were published between the 17th century and the 20th century. Twelve books, which are regarded as valuable, were published before the Imjin Waeran, the Japanese Invasion in 1592. The places where they published the books were scattered all across the country. Sixty two books were published in China, and three were in Japan. Many of the books housed by the Mukdam Museum were Buddhist ones, which were published by temples in and after the 17th century.

Purpose: The purpose of this study was to identify and compare the differences on perceived health status, Activities of Daily Livings (ADL), social support, and residential satisfaction between long-term care hospitals and nursing homes. Methods: Data was collected through questionnaires and interviews conducted from March 29 to April 22, 2011. The subjects were 66 old adults in 3 long-term care hospitals and 53 old adults in 6 nursing homes. Data were analyzed by Pearson’s correlation analysis and t-tests. Results: ADL and subjective health status in nursing homes were worse than those in long-term hospitals, but it was not statistically significant (p>.05). Old adults in nursing homes received more emotional support from other residents and staff, and received more instrumental support from staff than those in long-term care hospitals (p<.001). The mean scores of resident satisfaction in long-term care hospitals and nursing homes were 3.53 (SD= ±0.36) and 3.97 (SD= ±0.44), respectively. Resident satisfaction in nursing homes significantly was higher than long-term care hospitals (p<.001). Conclusion: Health care personnels in long-term care hospitals should enhance resident satisfaction and social support and need to coordinate long-stay patients with nursing homes.

학술연구 : 모당(慕堂) 손처눌(孫處訥)의 문인록(門人錄) 분석(分析)

연구결과 이들은 모두 대구 인근 지역에 거주한 문인들이다. 강학도서는 유학의 근본 경전인 四書를 기본으로 하고 『주역』·『춘추』 등 經書와 함께 程子, 朱子의 저술, 성리학, 예학에 이르기까지 다양한 학문적 관심을 가졌다고 볼 수 있다. 특히 퇴계서의 강론을 통해 대구를 중심으로 한 칠곡, 영천 등의 인근 지역에 퇴계학을 전파하였다. 따라서 이 자료는 당시 대구를 중심으로 손처눌 문하의 분포 범위와 학풍을 살필 수 있는 중요한 근거를 제공하고 있다고 볼 수 있겠다. 이와 같은 연구가 대구를 중심한 영남지역이라는 지역적 한계를 넘어 조선중기 사림들의 학풍을 이해하는데 조금이나마 기여할 수 있을 것으로 생각된다. The result of the study shows that the people mentioned in the Record of Confucian Literati by Cheo-nul Son, Pseudonym Modang were all residents of the Daegu area. They studied lecture texts, which basically included the Four Chinese Classical Books: Political Ethics (Daehak in Korean), Middle Ways (Jungyong in Korean), Confucian Teachings (Noneo in Korean), and Instructions by Mencius (Maengja in Korean). They were interested in a wide range of other texts such as the Chinese classics like the Book of Changes (Juyeok in Korean), and the Canon of History (Chunchu in Korean). They were also concerned with various writings by Chu Hsi and two Jeong brothers called Jung Hsi, other Confucian texts and etiquette manuals. By conducting lectures about Toegye``s writings, they disseminated the School of Toegye centering around Daegu and in the areas of Chilgok and Yeongcheon. Accordingly, this study provides an important foundation on which to build an examination of the academic trends and the distribution of Confucian literati following Cheo-nul Son around Daegu. Furthermore, this study is sure to contribute to an understanding of the academic trends of Confucian scholars in the middle Joseon Dynasty beyond the regional limitation of the Yeongnam area centering around Daegu.

학술연구 : 미국(美國) 하버드대학 옌칭도서관(圖書館) 한국본(韓國本) 고전적(古典籍) 고찰(考察)

본 연구는 미국으로 유출된 전적 중 하버드대학 옌칭도서관에 소장된 한국본 전적을 분석해보았다. 분석결과 주제별 분석에서는 왕정정치에 필요했던 史部전적이 207종으로 가장 많았으며, 그중 族譜, 榜目, 戶籍臺帳, 實紀類가 많았다. 자부에는 불교전적이 집부에는 소설류, 개인문집이 많았으며, 소설류는 모두 근대에 간행된 딱지본 및 한글본이 많았다. 귀중서에 해당되는 임란이전에 간행된 전적은 13종이며, 전적의 대부분이 19세기에서 20세기에 이후에 간행된 전적들이었다. 간행지 및 간행처가 명확히 밝혀진 전적은 50여종 이었다. 開刊된 전적은 최초의 간행본이라는 점에서 의의가 매우 크다 하겠다. 개간된 전적은 8종이었다. 판본별 분석에서는 필사본이 406종으로 대부분을 차지하고 있다. 국내에서의 傳存여부를 파악해 본 결과 전존되지 않는 전적은 60종이었다. 그러나 필사본을 포한한다면 466종으로 94.9%를 차지하고 있다. 이제 해외에 산재되어 있는 우리의 전적을 제대로 발굴하고 세계화시키는데 가장 중요한 일은 반출된 한국 전적의 반환운동과 함께 전적의 수집은 보다 장기적인 계획을 수립하여 지속적으로 추진해야 할 과제이다. 그 첫 단계로 소장 국가의 우리 전적에 대해 심도 깊게 파악하고 양측이 모두 합리적인 방향으로 정보를 공유할 수 있는 협정을 맺는데 노력해야 할 것이다. This study has analyzed old books printed in Korea but housed by the Harvard-Yenching Library in the USA. Referring to the analysis of the subjects of these books, history books account for the majority: there are 207 kinds of history books which record kings’ reign. They also include family genealogies, registers of those who passed the national exams, family registers, and practical writings. As for books about philosophies and religions, those on Buddhism take the largest portion. With regards to literary books, novels and individual anthologies occupy the majority. Many of the novels are found to be mostly movable print books and written in Korean. There are thirteen kinds of valuable books, which were published before the Imjin Waeran (the Japanese Invasion in 1492). Most of the books surveyed are found to have been published in the 19th and 20th century. There are about fifty kinds of journals and books whose publishers are clearly known. First issued journals are meaningful in that they were the first journals published. There are eight kinds of first issued journals. Referring to the analysis of printing types, there are forty six kinds of hand-written books, which account for the majority. A search of their existence in Korea indicates that sixty kinds of these books no longer exist in Korea. However, including hand-written books, the number of kinds of books that are no longer found in Korea has increased to 466. These kinds of books account for 94.9%. When finding books which originally belonged to Korea, and making them known to the world, it is necessary to make a long-tern plan and promote a lasting campaign to restore and recollect them. It is also important to understand the attitudes of countries toward the books which keep those books originally owned by Korea, and to make efforts to reach an agreement to share information about those books in a reasonable way.

분석결과 주제별 분석에서는 집부의 개인문집과 사부의 전기류가 많이 소장되어 있었다. 국내에서의 傳存되지 않는 전적은 295종이었다. 장서인이 찍힌 전적은 132종이며, 장서인의 종류는 257종이었다. 내사인과 내사기가 있는 전적은 44종이며, 내사인의 종류는 5종이 있었다. 해외에 산재되어 있는 우리의 전적을 제대로 발굴하고 세계화 시키는데 가장 중요한 일은 반출된 한국 전적의 반환운동과 함께 전적의 수집은 보다 장기적인 계획을 수립하여 지속적으로 추진해야 할 과제이다. 그 첫 단계로 소장 국가의 우리 전적에 대하여 심도 깊게 파악하고 양측이 모두 합리적인 방향으로 정보를 공유할 수 있는 협정을 맺는데 노력해야 할 것이다. As a result of the analysis, many books in the Jip-category of personal collections and Sa-category of biographies were found to be part of the theme analysis. 295 kinds of these books no longer exist in Korea. The books with ownership stamps were 132, and the kinds of owner stamps were 257. The books with inner stamps and records were 44, and the different kinds of inner stamps were 5. In order to locate Korean books scattered overseas and make them known to the world, it is most important to establish long-term plans and promote them consistently with the aim of having them returned from overseas. As part of the first stage of such efforts, we should throughly understand the attitudes of the countries toward the Korean books that are housed by them, and try to reach an agreement to reasonably share the information of the books.
