Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

ATM 망에서 원격제어 에이전트 시스템을 위한 연결 설정 방법에 관한 연구

최길환,배상현 조선대학교 통계연구소 2000 統計硏究所論文誌 Vol.2 No.1

The ATM networks must accommodate diverse types of applications with different quality of services(QoS) and traffic characteristics, which may be require point-to-point connection or multipoint connection. Thus, in order to increase the utilization of the networks and satisfy the Qos's of each traffic type, some types of traffic control schemes must be adopted in ATM networks. However, they have problems in establishing connections over multiple sub-networks, such as no end-to-end connections, transmission delay due to ATM address resolution, no QoS protocols. The major design consideration of this remote control agent system is that the ATM API is included by the existing network. In this work, we study the agent architecture based on the ATM nets and the network control capability to allow creation of more intelligent service as well as existing broadband multimedia service. We propose a new connection management scheme in the thesis to improve the connection management involved. In this thesis, the service agent connection for the ATM nets are proposed and their performances are analyzed. In this thesis, the main objective of this dissertation work is to investigate the performance of traffic control schemes for ATM agent connection.

地方政府의 TQM 導入에 관한 硏究

趙昌鉉,崔吉洙 한양대학교 사회과학대학 1998 社會科學論叢 Vol.17 No.-

Total Quality Management (TQM), based on management theories of W.Edwards Deming, Joseph M. Juran, Philip Crosby, Walter Shewhart, etc. was eagerly adopted by the public sector of a number of countries including the United States in the 1990s. Scholars who study TQM generally agree that its benefits outweigh its disadvantages. This paper aims to discuss TQM as a management technique to improve public administration generally and show the feasibility of introducing TQM in Korea's local governments. In this paper, TQM is defined as a "process in which local governments set and implement their policy priorities such as satisfying the needs of their customers (public officials internally and residents externally), continuously improving administrative efficiency, and enhancing the quality of public services." How to apply TQM to the public sector is a subject of heated debate. First, as James E Swiss et al argue, the concepts and tools of TQM may be adopted to the unique environment of the public sector. On the other hand, Michael E Milakoblch and others contend that public organizations should be changed before TQM is introduced into the public sector in consideration of 1) difficulty in defining the customer, 2) organizational culture, 3) decision-making processes, 4) focus on output, 5) regulatory restrictions, and 6) corruption in bureaucracy. Still others including David Osborne and Ted Gaebler propose that TQM should be introduced into the public sector through various approaches. These approaches include 1) a promotive government, 2) a competitive government, 3) a business-minded government, 4) a performance-oriented government, 5) a customer-oriented government, 6) a preventive government, 7) amission-focused government, and 8) a decentralized government. The successful introduction and implementation of TQM in local public administration require the following series of stages : The first is a preparation stage. During this stage, among others, awareness about TQM is raised ; key members of the organization are trained in TQM ; visions are presented; objectives and policies are developed ; and TQM implementation processes are explained. Next is the planning stage, when a detailed implementation plan is established ; supporting organization is determined; and necessary resources are mobilized to achieve goals. In the third stage, analysis is carried out. During this stage the entire organization should be aware that the organization can be improved ; action plans should be developed based on the assessment of the current organization; and customer needs and expectations should be identified. During the fourth stage, all related people should implement action plans. Last, the organization should institutionalize experience and understanding obtained through the implementation of TQM. Considering the present conditions of local governments of Korea, it is desirable to develop a long-term strategy and apply the concepts and tools of TQM first to departments and agencies that are ready to implement them and gradually extend them to other departments and agencies.

정종현,이길홍,최칠남,노학,백승남,이상열 대한치과기재학회 1999 대한치과재료학회지 Vol.26 No.2

The corrosion resistance of Ti-Zr-Pd-Cr alloys were investigated in order to reveal their possible use for new biomedical implant materials. Titanium alloys consisting of 10∼20%Zr, 0.0∼0.4%Pd and 0.15%Cr were prepared by vacuum arc-melting as alloying elements instead of using hardness Al and V in response to recent concerns about the long term safety of Ti-6%Al-4%V ELI alloys. The Ti-Zr-Pd-Cr alloys were heat-treated at 1000℃ for 2hrs under a vacuum atmosphere. The effect of Zr and Pd Ti alloys on the corrosion resistance for biomedical implant was investigating the anodic polarization curve at 37℃ in 5%HCI solution deaerated by high-purity N₂gas bubbling. The critical current density for passivation(I ) of Ti-Zr-Pd-Cr alloys didn't reveal markedly. Passive current density(I ) at 1.0V vs. SCE of this alloys decreased with increasing Zr in the contents from 10 to 20% and decreased with containing Pd in the range from 0.2 to 0.4%. Potential(E ) at 0.1A * m-² of this alloys increased with increasing Zr in the contents from 10 to 20% and increased with containing Pd in the range from 0.2 to 0.4%. For the Co-30%Cr-6%Mo alloy, passivity zone is narrow, and rapid increase of current density result from the low potential in comparison with Ti and Ti alloys. The corrosion resistance by the anodic polarization of Ti-20%Zr-0.2%Pd-0.15%Cr alloy was found to be superior to those of the Ti, Ti-6%Al-4%V alloy and Co-30%Cr-6%Mo alloy. The passive films formed on the Ti-20%Zr-0.2%Pd-0.15%Cr and Ti-6%Al-4%V alloys in the anodic polarization test consist mainly of TiO₂, Ti compound, ZrO₂, Al₂O₃and V₂O₃.

윤현구,정호연,양인명,김성운,김진우,김광원,김영설,최영길,서광식 대한내과학회 1992 대한내과학회지 Vol.42 No.1

MC₃T₃-E₁골아세포군을 이용하여 IGF-Ⅰ과 Ⅱ를 투여하고 DNA합성과 골아세포기능을 측정하기 위해 PTH에 대한 C-AMP반응정도, alkaline phosphatase 활성도를 측정하여 다음과 같은 결과를 얻었다. 1) IGF-Ⅰ과 Ⅱ는 모두 DNA합성이 어느 농도까지는 증식효과를 나타내지만 그 이후에는 억제되는 양상을 보였다. 2) PTH에 대한 골아세포의 C-AMP반응으로 증가되었지만 IGF-Ⅰ과 Ⅱ의 투여시 농도변화에 따른 의미있는 변화는 없었다. 3) 본 실험의 조건에서 alkaline phosphatase 활성도는 증가되지 않았다. 이상의 결과로 MC₃T₃-E₁ 골아세포에 IGF-Ⅰ과 Ⅱ는 세포의 증식을 자극하여 PTH는 C-AMP생성을 촉진하는 효과가 있었다. The effect of insulin-like growth factor (IGF) Ⅰ and Ⅱ on cloned MC₃T₃-E₁ cells that had osteoblastic activity was examined by [³H] thymidine incorporation into DNA, cyclic AMP responsiveness to parathyroid hormone (PTH), and alkaline phosphatase activity. IGF Ⅰ and Ⅱ stimulated the growth and proliferation of osteoblastic cells at 20ng/㎖ and 50ng/㎖, respectively. We next examined the effect of IGF-Ⅰ and Ⅱ on the expression of osteoblastic activity. Adenylate cyclase response of PTH to IGF-Ⅰ and Ⅱ-treated cells showed maximal stimulation at 10 and 50㎚PTH, respectively, but IGF Ⅰ and Ⅱ induced limited activity of osteoblastic function. In conclusion, IGF-Ⅰ and Ⅱ were potent stimulators to the growth of osteoblastic cells but did not have an immediate effect on expression of osteoblastic function in this experiment.

인터넷상에서 Ontology를 이용한 정보의 분류와 획득을 위한 지능형 에이전트의 설계

양성기,이광옥,최길환,오창윤,배상현 조선대학교 통계연구소 2000 統計硏究所論文誌 Vol.2 No.1

In this paper, we propose a new method of information gathering and text classification based on Internet. The number and diversity of information resources on the internet is increasing rapidly. As more information become available on the internet, it becomes increasingly difficult to acquire knowledge we need. A number of tools are available to help people search for the information they need. However, These tools are unable to interpret the result of their search due to lack of knowledge of domain. We need more intelligent system which facilitates personal activities of producing information such as surveying, writing paper and so on. We Implemented a system called ⅡRS(Intelligent Information Retrieval System) which helps people to acquire knowledge form information resources on the internet by gathering information and classification texts. It specifies the common background knowledge shared by the user and ⅡRS, allow ⅡRS to make inexact match between the user's request and the candidates, assigns user-oriented categories. We tested ⅡRS for gathering pages on the WWW and classification articles on the network news. The result of the experiments indicated that the ontology based approach enable us to use heterogeneous information resources on the internet.

Bromocriptine 과 Cyproheptadine 이 Corticotropin-releasing Factor(CRF) 로 자극된 ACTH 분비에 미치는 효과

김진우,최영길,김영설,김광원,김선우,양인명,윤현구,우정택 대한내과학회 1986 대한내과학회지 Vol.31 No.5

Our study was desinged to observe the ACTH response to ovine CRF in healthy men and to observe the effect of bromocriptine or cyproheptine on ACTH and cortisol response induced by ovine CRF in healthy men. We have hypothesis that if hromocriptine or cyproheptatine inhibits the secretion of ACTH induced by ovine CRF, they decrease the secretion of ACTH in the pituitary level. The result were followings: 1) Plasma ACTH reached a peak of 1.5 and 1.6 times the basal level in response to ovine CRF at 10 min, and 30 min, respectively and decreased to the basal level at 90 min. 2) Cyproheptadine or bromocriptine did not inhibit the response of ACTH to ovine CRF. 3) We suggest that cyproheptadine or bromocriptine does not inhibit the ACTH secretion in the normal pituitary gland.
