In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

This study develops an integrated logistics planning model for determining optimal patterns of supply centers and inventory allocation. This research addresses the formulation of those complex two-echelon logistic system planning problems incorporating location, resource allocation and optimal delivery based on minimizing the amount of shortage and damage from shortage of supplies and travel distance or time. The solution method developed to solve the problem applies a three step sequential approach, those are : - first step, supply center location and inventory allocation using stochastic set-covering problem, - second step, optimal sector-clustering to support the unit forces, - third step, optimal vehicle route scheduling based on genetic algorithm. Also, we have developed computer programs for each steps and have shown the results of sample non for supply delivery problems in a hypothetical battle area. It was known that the proposed model was a very acceptable for the optimal supply delivery considering inventory allocation and vehicle routing problems.

The local varieties of turnip were collected from five districts in Korea and were selected the superior lines and the experiments were caried out to obtain data for breeding F_1 Hybrid. The results obtained are as follows : 1. Local varieties of turnip were collected from Kanghwa and Ichun in Kyunggi province, Uisung and Bonghwa in Kyungbuk province, and Taegu district. From each of five local varieties, one line was selected, respectively, which showed high homogeneity, superior practicality and significant difference in agronomic characters. 2. Kanghwa local variety showed very low T/R ratio because of the heaviest root weight and the least number of leaves with relatively light leaf weight, on the other hand, Uisung local variety showed very high T/R ratio because of the lightest root weight and relatively many number of leaves with somewhat heavy leaf weight. And it was appeared significant differences in quantitative charactes among these local varieties. 3. In flesh texture and color of root, kanghwa local variety showed weak hardness with light pink, Bonghwa local variety showed strong hardness with light wellow and other local varieties showed medium hardness with white, respectively. 4. The five local varieties and 20F_1 progenies were tested for the heterosis and the combining ability of leaf and root characters. Heterosis was remarkable in seven characters, especially in root weight, root diameter and leaf weight. 5. General combining ability(GCA) and specific combining ability (SCA) were significant in all characters. In the effect of GCA, Uisung local variety was high in the leaf weight, Kanghwa local variety was high in the root weigh. In the effect of SCA, both leaf weight and root weight were proved to be high in the F_1 combi-nations from Using local variety used as parent.

황성호,오주현,임해진 三陟大學校 1999 論文集 Vol.32 No.1

An ATM multicast switch which can effectively accommodate diverse classes of traffic, is the core component of broadband ISDN. In this paper, we proposed a new call scheduling algorithm assigning priority according to the quality of service under the diverse traffic environment in multicast switch. The algorithm presented in this paper is using unfairness of switch structure, and delay-sensitive traffic may be given the high priority such that it can be transmitted as soon as possible. Also, we proposed a new hardware structure for the algorithm which can be constructed with combinational logic gates and it is beneficial for high-speed operation and VLSI implementation. The results of simulation for performance evaluation show that mean waiting time of delay-sensitive call is considerably reduced.

The current study was designed to evaluate the positive rates of arthropod allergens by Korean inhalant panel of MAST-CLA in patients with allergic rhinitis. One hundred sixty patients, diagnosed to allergic rhinitis in an Out Patient Center of Soonchunhyang University Chunan Hopsital during Aug 1998 to July 2000, were studied. 1. The overall positive rate among 35 specific allergens was 59.4% (95 patients). 2. The arthropod related allergen accounted for 82.1% (78 patients) of the positive rate. 3. Each positive rate of Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), house dust (Hd), and cockroach mix (Cm) was 45.0% (72 patients), 43.1% (69 patients), 28.1% (45 patients), and 8.8% (14 patients), respectively. 4.Significant agreement between arthropod allergens was observer (P < 0.05). 5. The obseved agreement between Df and Dp was 95.6%, showing most significant Kappa index (Kappa = 0.911, P < 0.001). There results suggested that although MAST-CLA is a useful measure of identifying specific allergens, the specificity of two mite allergen relatively low, implying because of common allergen between mites in Korean panel of MAST-CLA. Our data also supported that arthropod is the major cause of allergen in patients with allergic rhinitis, however, the MAST-CLA should be modified in order to exclude common allergen of mite and to include more specific mite allergen.

본 연구에서는 교사-유아 간 애착안정성 정도에 따라 유아의 스트레스 정도 및 유아의 스트레스 대처행동에 어떠한 차이가 있는지 알아보고자 하였다. 연구 문제에 따른 연구 결과는 다음과 같다. 첫째, 교사-유아 간 애착안정성 정도에 따른 유아의 스트레스 정도에는 통계상 유의미한 차이가 없었고, 유아 스트레스 하위 영역인 교사, 또래, 학습 환경에서도 통계상 유의한 차이가 없는 것으로 나타났다. 다만 학습 활동영역에서 교사-유아 애착안정성이 낮은 유아 집단이 높은 집단보다 스트레스를 더 많이 받는 것으로 나타났다. 이러한 결과는 교사-유아 애착안정성 정도에 따라 교사, 또래,학습 환경 요인과 관련된 유아 스트레스에 차이가 없으며, 교사-유아 애착안정성이 높을수록 유아가 학습활동 요인과 관련된 스트레스를 덜 받는다는 것을 알 수 있다. 둘째, 교사-유아 간 애착안정성 정도에 따른 유아의 능동적, 수동적, 신비적 스트레스 대처행동 양식에서 통계상 유의한 차이가 나타났다. 교사-유아 간 애착안정성 정도가 높은 집단이 능동적 대처를 더 많이 하고, 교사-유아 간 애착안정성 정도가 낮은 집단이 수동적 대처와 신비적 대처를 비교적 더 많이 한다는 것을 알 수 있다. Due to lack of systemic program regarding physical activity in children, the study is to identify the constitution and development of the Natural Physical Activity Program by offering environmentally friendly elements such as wind, sun, mountain, sea, river, tree, flower, field for children. We expect children to learn the relation with nature, respect for life, understanding and love, importance of working together, and etc. The research questions for the purpose of this study are as followed: First, this study is going to identify the overall awareness and its needs of the Natural Physical Activity Program among preschool teachers. Second, we will look over how we can develop such program for preschool teachers. And a direction proposal on Natural Physical Activity Program. About 250 preschool teachers resided in Busan and Gyug-nam province were urged to participate in a research questioning their awareness and needs of the program. Among 250 preschool teachers, we choose 20 of them to interview about the goal, plan and development direction of the program. The result of the study is following as: First, most of the preschool teachers have a positive view on the Natural Physical Activity Program, and they agree that the program is highly needed to use. However, it is urge that overall education environment need to be improved to achieve its goal of the program. Second, the interview on the development direction is categorized as need, development direction, teaching method, evaluation method, activity, problem, improvement, solution, and etc. and, Third, the contents of the program include environmentally friendly elements such as wind, sun, mountain, river, sand, tree, flower, field to induce children’s interest and whole-person education. The contents of the program are expected to deliver hands-on experience for children. And also, the program includes physical activity using a nature object. Based on the potential problems we identified, a next study is expected to deal with following points. First, more empirical research is needed to prove the effectiveness of the program in a broad way by proposing a program that can be applicable at child-education center. Second, the study developed contents to make children feel enjoyable about nature. Unfortunately, in-depth research and development of such program is not sufficient. In this respect, more continuous research on Natural Physical Activity Program is required and need to be widely established.

해운기업의 경쟁력 확보와 선박의 안전성 향상을 위해서는, 연근해를 주 무대로 하여 항행 또는 어로 작업에 종사하고 있는 노후선과 기준미달선에 효율적인 해상안전 관리 체제의 구축이 절실하다. 본 연구의 가설 검정에서 해상안전 관리체제의 선진화, 선사의 자율적인 안전관리체제 구축, 안전관리의 제도적 지원 체제 및 선박 종사자의 자질 향상이 모두 물동량 증대, 시장점유율 증대, 비용절감 및 서비스 개선 등의 선사 성과에 대하여 긍정적으로 반응하였다. 이와 같은 결과에 따라, 선사의 운송서비스의 질을 제고시키고 경쟁력을 증대시키기 위해서는 첫째로, 현재 낙후되어 있는 해상안전관리체제를 선진화하여 구축하고, 항행질서를 혼탁하게 하는 연안선박의 안전항행을 위해 이제는 연안선박에도 ISM Code를 단계적으로 도입하여 시행할 것이다. 그리고 ISM code를 시스템적으로 지원하고 관련자들의 자질 향상을 도모해야 할 것이다. The effective management system for ocean safety may be one of the key factors for shipping companies to grasp competitive edge and to guarantee the safety of their ships as well. By pointing out weaknesses of the shipping industry, this paper argues that the implementation of such management system is vital especially for the overage and below-standard ships which operate in the neighbouring waters of the Korean Peninsula. Abstract: The empirical study finds out that some major variables effecting the ocean safety, such as advanced system of ocean safety management, implementation of self-controlling safety management in shipping companies, institutional support system towards safety management and quality improvement of staffs, hold positive relationship with the dependent variables which depicts the managerial achievements, such as magnitude of cargo transportation, market share, decrease in cost and improvement in. The empirical results indicate that the phase-in of the ISM Code may be the best strategy to cope with the current adverse circumstances. And, of course, the adoption of the ISM Code should satisfy the precondition that it is systematically implemented and companies should put endeavours for enhancing the qualities of their staffs.
