Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

오늘날의 측량의 내용은 우주측지기술의 실용화, 컴퓨터를 이용한 수치지도제작 및 인공위성에 의한 영상의 획득이 가능해짐에 따라 종래의 지상측량 및 지도제작의 범위를 뛰어넘어 크게 확대, 발전되고 있다. 그러나 우리나라의 측량학계는 이러한 시대적 변화를 능동적으로 주도해 가지 못하고 있으며, 내부적으로는 제도적, 기술적인 여러 가지 문제점을 안고 있고, 또한 측량업과 측량기술자의 위상은 사회적 공헌도에 비해 열악한 상태에 처해 있는 것이 오늘의 현실이다 따라서 본 연구에서는 우리나라 측량의 현황과 문제점을 조사, 분석하고 측량기술의 발전과 측량업의 건전한 육성을 위한 여러 가지 방안을 연구, 검토하여 미래지향적인 발전지표를 제시하고자 하였다. Nowdays the scope and the contents of surveying are enlarged from a small area of the conventional surveying and mapping to a large area of the practical use of space geodesy technology, digital mapping using computers and the development of remote sensing. However, there are many structual, technological problems on the Korean surveying and mapping field, therefore they cannot actively lead the new tendency of current movement of surveying. The social status of survey engineers and the surveying and mapping industry is lower than it deserves for its social contribution. In this paper, the present status and problems of Korean surveying and mapping field are reviewed and analysed, and proper scheme for future development of the field with the prospect of surveying technology and the sound cultivation of surveying industry is proposed.

The purpose of the present study is first to find out the expectations of members of the Council of Sports Coaches for People with Disability, and second, to classify respondents according to their expectations and to investigate the correlation between these expectations and their personal characteristics and desire to engage in volunteer activities. A survey, replicating an earlier study, was carried out, targeting 1000 members of the Council of Sports Coaches for People with Disability in H prefecture during January and February 2004. There were 52 valid responses, representing 48.4% of respondents. The major findings are summarized as follow: 1. There was a strong overall tendency for members to expect to meet and interact with the disabled, as well as with other volunteer associates, and to be eager for self-development. A factor analysis of expectations in relation to activities revealed 5 factors: interaction with associates; social contribution; social benefit; the offer of sports skill; and better use of life. Likewise, a cluster analysis of each factor resulted in classifying the council members into five groups: those who wanted interaction with associates; those who offered sports skills; those who wanted passive participation; those who wanted social contribution; and those who offered disability support. 2. The council members' wishes for volunteer services include caring for the disabled and administering tournaments and club activities, but tournaments have a higher priority. Also within the field of sports coaching, they wanted to act as practice partners more than coaching and refereeing. The survey found that there were a variety of expectations. There has been little consideration given to council members' expectations about the volunteer activities they engage in, This study reveals that the kind of volunteer service they hope for depends on what they expect from those activities, such as assigning volunteers by taking into consideration their expectations concerning activities and the kind of volunteer service they hope for.

This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

Carcasses from thirty (male : 12, female: 18) Korean Cattle were used to study the yield of meat cuts by the conventional cutting method as well as the American method. The dressing percents and correlation cofficients among meat cuts in a carcass were also investigated. The regression equations for predicting the total carcass lean from meat cuts is of particular importance in studies of carcass evaluation. Physical separation of the entire carcass is laborious and costly. Therefore, a simple indirect method for predicting total carcass lean would be extremely useful. The regression equations of total carcass lean on certain meat cuts were calculated in this study. Dressing percents from male and female carcasses were 49.64%, 48.37% respectively. Comparing the dressing percents of Korean cattle with idealized beef cattle, the percents from Korean cattle were much below those from beef. The percents of round, chuck, and shortloin from Korean cattle were also lower than those of beef cattle. Correlation coeffidient between carcass and lean weight was highly significant. Correlation coefficients among meat cuts were highly associcted with carcass weight. Therefore, the results of this study indicate that using the regression equations is possible for predicting total lean from certain meat cuts.

The Balanced anesthesia has many benefits such as no air pollution, no hepatic or renal toxicity and postoperative pain relief compaired with inhalation anesthesia. The Study pointed out differences of cardiovasular change, serum glucose and cost among Inhalation (Enflurane), Propofol and Midazolam-Fentanyl. Thirty-three patients of ASA class I or II scheduled to undergo elective operations were classified randomly into 3 groups. Enflurane group(E) was induced with thiopental sodium 5.0mg/kg and maintained with 1.5-2.0 vol% Enflurane and 50% nitrous oxide. Propofol group(P) was induced with propofol 2mg/kg and maintained by the continuance of a intravenous infusion of propofol 6mg/kg/hr with which is supplied 50% nitrous oxide. Fentanyl group (F) was induced with midazolam 0.1mg/kg and fentanyl 4g/kg and maintained by the continuance of a intravenous infusion of fentanyl 4-6 g/kg/hr and midazolam 0.2mg/kg/hr with which is supplied 50% nitrous oxide. The results were as follows : 1. Systolic arterial pressure was increased significantly in two group (E & P group) at 1 min. after intubation (p<0.01) and decreased in three groups (E,P & F) at 10 min. after intubation (p<0.05). 2. Diastolic arterial pressure was increased in E group at 1 min. after intubation (P<0.01) and decreased in P group at 5 min., 10 min. after intubation (p<0.05). 3. Heart rate was significantly increased in E group at 1 min., 5 min. after intubation and P group at 1 min. after intubation (p<0.05). 4. Serum glucose was significantly increased in three groups at 60 min. after skin incision (p<0.01). 5. Cost was lower in P group than E and F groups.

4*(M/M/1)시스템에서 로컬 및 글로벌 실시간 처리를 위한 스케줄링 알고리즘의 시뮬레이션 분석

최용락,윤희환 대전대학교 기초과학연구소 1990 自然科學 Vol.1 No.-

본 논문은 동종의 프로세서로 구성된 분산처리 시스템에서 엄격한 실시간 처리제한을 갖는 정기적 프로세스의 로컬 스케줄링 및 비정기적 실시간 처리 프로세스와 일반 프로세스의 글로벌 스케줄링 알고리즘에 대한 시뮬레이션 성능 분석을 하였다. 시뮬레이션 결과 로컬의 정기적 실시간 프로세스에 대한 deadline이전 처리를 100% 보장하면서 글로벌 스케줄링을 수행함으로써, 비정기적 실시산 프로세스이 deadline miss ratio가 명백히 감소하였고, 시스템 전체에 대한 load imbalance 및 response time이 개선됨을 보였다. This paper presents a scheduling algorithm for processes with hard real-time constraints which works dynamically in loosely-coupled distributed systems. It includes scheduling problems to guarantee periodic and non-periodic processes with execution deadlines, and it also takes account into preemption, overhead due to scheduling, and the effect of normal processes without strict time constraints. The results of simulation show that this algorithm reduce deadline miss ratio, average response time, and root mean square difference in work load substantially.

The ultimate goal of periodontal disease therapy is to promote the regeneration of lost periodontal tissue, there have been many attempts to develop a method to achieve this goal. The purpose of this study was to evaluation the effects of BBP, DLB on bone formation in human fetal osteoblasts. We examined the effect of BBP, DLB on collagen synthesis of human fetal osteoblasts. Collagen synthesis level of 5mg of BBP(5.80±0.18㎍/mg/ml), DLB(5.51±0.57㎍/mg/ml) showed significant difference compare with control group(3.58±0.35㎍/mg/ml). We also examined expression of BMP-2 by Western blot analysis. BMP-2 was expressed in both of BBP and DLB. These results suggest that BBP, DLB have an inductive effect on bone formation in vitro increasing with collagen synthesis and expression of BMP-2.
