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.

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 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%).

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.

Hemifacial microsomia is a common congenital craniofacial deformity involving bone and soft-tissue. Mandibular hypoplasia is the most obvious skeletal manifestation of hemifacial microsomia. In the past, complete realignment of the skeleton was preferred to soft-tissue correction, which was clearly second choice. However, in this study, simultaneous correction of bone and soft tissue deformities were equally important in treatment of hemifacial microsomia. One-stage and simultaneous bone and soft tissue reconstruction is possible and staged operations of the skeleton and soft tissue are no longer necessary, except in special cases. Even in children and adolescents, good results and normal growth potential can be achieved with simultaneous correction of bone and soft tissue.

Sex-role development is one of the essential tasks of child development and a part of one's personality. Many studies have been undertaken to examine the children's sex-role preference and verified the difference between boys and girls. There are many factors that effect on the children's sex-role preference. For example, there is home environment that is included parents, -family structure, home's social level, brothers and sisters' formation and birth-rank,... etc. Also, there is social environment that is included peer, teacher and mass media. But we can expect that preschool children are most effected by parents. Thus the present study was undertaken to examine the influences of father dominance on preschool children's sex-role preference. This study is aimed to find out the follows facts. 1. Degree of father dominance that is perceived by child. 2. To find out father dominance has any influence on the boy's sex-role preference. To find out father dominance has any influence on the boy's sex-role preference under each of four lowranking domains, that is, decision-making, competence, nurture and limit setting. 3. To find out father dominance has any influence on the girl's sex-role preference. To find out father dominance has any influence on the girl's sex-role preference under each of four lowranking domains, that is, decision-making, competence, nurture and limit setting. The dependent measures are 1. Toy Preference Test. 2. Father dominance examination used Father Dominance Test (Henry, B. H.) Subjects were obtained from 100 boys and 100 girls, that they were all preschool children in Daegu. For statistical analysis, Mean, the Standard Deviation, t-test, one way ANOVA and Scheffe's test were used. The levels of significant were established at 0.05 and 0.01. The results were as follows 1. Generally, both boys and girls have perceived father dominant more than mother. In case of boys, they perceived father dominant more than mother in domains of decision-making and competence. In case of girls, they perceived father dominant more than mother in domains of decision-making, competence and nurture. 2. Father dominance perceived by young children had effects on boy's sex-role preference. In general, the higher father dominance was, the higher boy's masculinity was. In domains of decision-making, competence and nurture, father dominance have significant influences to boy's sex-role preference, but in domain of limit-setting, father dominance have no significant influence. 3. Father dominance perceived by young children had effects on girl's sex-role preference. In general, the higher father dominance was, the higher girl's feminity was. In domains of decision-making and limit-setting, father dominance have significant influences to girl's sex-role preference, but in domains of nurture and competence, father dominance have no significant influence on the girl's sex-role preference.

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.
