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.

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.

The chronic suppurative otitis media is one of the most common disease in the otologic field. And the works on bacterial distribution of chronic suppurative otitis media were studied by many otologist, but there is some difference. The bacteriologic study was done on 126 cases of chronic suppurative otitis media who visited the Department of Otolaryngology, Chosun University Hospital between January 1989 and December 1989 and the following conclusions were obtained. 1) In sex distribution, the male had higher incidence rate than female (M: 56.3%, F:43.7%). 2) In age distribution, 3rd decade (34.1%), 2nd decade (34.1%), were most prevalent. 3) In duration of the disease, the hightest frequence was below 5 years duration 4) Among 126 cases, 98 cases(77.8%) were unilateral (right ear was 47 cases(37.3%) and left ear was 51 cases(40.5%))and 28 cases(22.2%) were bilateral. 5) The 136 cases(88.3%) showed the positive results under culture, but 18 cases(11.7%) didn't growthed. Among 136 cases 95 cases(61.7%) had single infection and the 41 cases(26.6%) had mixed infection. 6) The most frequently isolated bacteria was staphylococcus(38 strains, 27.9%) and next were proteus(27 strains, 19.9%) and pseudomonas (22 strains, 16.2%). 7) The Staphylococcus was sensitive to cephalothin(94.7%), amikacin(78.9%) and resistant to penicaIin(63.2%). 8) The Proteus was sensitive to amikacin(92.6%), cephalothin(88.9%) and resistant to minocycline(81.5%) and gentamicin(70.4%). 9) The Pseudomonas was sensitive to amikadn(86.4%), gemtamicin(59.1%) and resistant to minocycline(90.9%), ampicillin(86.4%) and cephalothin(86.4%).

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.

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.

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 purpose of this study is to examine the kinematic characteristics of starting phase of players weared clap and normal skate in speed skating. The subjects of this study were current members of high ranked skaters in university. The Direct Linear Transformation(DLT) technique was employed to obtain 3-D position coordination of 22 joint points. Butter-worth low-pass filtering method was used to data smoothing at cut-off frequency of 7.4Hz. From the results of this study, the following conclusions were drawn; 1.At the of landing, male athlete showed slightly fast time in the first left-step and they also showed take-off by fast swing motion during gliding. 2.To get propel acceleration, female athlete showed large tranverse displacement and, on the other hand, male athlete showed large horizontal displacement. According to this results, COG showed steep change of motion in the high position during starting. 3.In the velocity of COG, both male an female athlete show a gradual rise-pattern of the velocity rate, In the velocity of skate front blade, they showed the swift change of the velocity during the second and third phase. 4.In the front angle of trunk, both and female athlete showed the big motion of trunk by the change of angle. In the angle of lower-segments, the better record athlete have, the faster motion of flexion and extention. Especially, female athlete showed the flexion of the angle-change and do not fast swing. In the knee, male athlete show take-off motion as increasing angle of left knee during starting, On the other hand, female athlete showed unnecessary pre-motion by decreasing knee angle and increasing it again.

Normally at a flood season the operation of the dam depends on a short range weather forecast that makes many difficulties of the management at a dry season. It is needed to study the pattern of the long period rainfall. The concept of PMP(Probable Maximum Precipitation) was used for designing dam. From the concept, this study is applied the concept of monthly probable maximum precipitation for operating dam. It can be possible to let us know the appropriateness of a limiting water level at a rainy season. For the operation of dam at a dry season this study can predict roughly the flood season's pattern of precipitation by month or period, therfore the prediction of precipitation can rise efficient operation of a dam.

Storage mites are believed one of the most important allergens in farmers and rural regions. Tyrophagus putrescenitiae, belonging to storage mites, is found not only within storehouses but also in the house dust, and the third most common mites following Dematophagoides farinae and Dermatophagoides pteronyssnus in house dust in Korea. The sensitization rate to Trophagus putrescentiae was reported as high as that of house dust mite in patients visiting the allergy clinic in large cities in Korea. We experienced a 69-year-old man who had suffered from dyspnea, wheezing, and coughing for 10 years. He retired from the teaching profession, and had lived in a large city. Deajeon. The skin prick test showed a positive reaction to Tyrophagus putrescentiae and negative reactions to house dust mites. The bronchial challenge test with Tyrophagus putrescentiae showed late asthmatic reaction. We confirmed a Tyrophagus putrescentiae induced asthma in non occupational setting.
