        • 에이전트를 이용한 WWW상의 가상 개별 교수시스템 설계

          문의영,서재현,김태공 인제대학교 1999 仁濟論叢 Vol.15 No.1

          최근 교수-학습환경이 시공간을 벗어나 가상공간에서 대두 되고있는 가상 학습을 통해 학습자 중심의 원격교육 환경으로 급속히 변천해 가고 있다. 하지만, 대체적으로 교육 시스템은 단순히 단방향적인 일관된 정보전달과 수동적인 학습을 통해 정보주입식 교육이기 때문에 보다 지능적이고 효과적인 학습자중심의 상호작용의 정보를 주고 받으면서 개개의 학습능력에 적합한 교육을 시행함으로써 이에 학습자는 보다 능동적으로 정보를 습득해 자신의 정보로 만들수 있는 교수 시스템을 요구하기에 이르렀다. 본 논문은 이러한 효율적이고 학습자 중심의 교수 시스템을 위해 상호정보 교류역할을 하는 에이전트를 두어 유연성 있는 가상 교수 시스템을 설계하는데 중점을 두었다. Recently, tutoring-learning enviromment is changing rapidly. The learner-centered remote education system with cyber study appeared in caber space beyond space-time. However, generally, because the current education system is the information cramming system which is consistent information transmission and passive learning, learners need the tutoring system that make him to take his information actively. This requires the suitable teaching with individual ability, giving and taking more intelligent and effective leaner-centered information. For this efficient leaner-centered tutoring system, in this paper, we design a flexible cyber tutoring system with the agent fo information interchange for each other.

        • 소프트웨어 콤포넌트 재사용 프로세스 지원을 위한 도구

          문의영,김태공,서재현 인제대학교 1999 仁濟論叢 Vol.15 No.1

          소프트웨어 개발 위기의 원천은, 갈수록 소프트웨어가 비대해지고 있다는 데 있다. 소프트웨어의 개발자들은 새로운 버전이 개발할 때마다 관련된 새로운 기능들을 가능한한 많이 추가한다. 이 기능을 모두 이용하는 사용자는 극히 드물다. 이로인해 재사용의 중요성이 부각되면서 객체지향 기술을 보완 할 수 있는 컴포넌트와 관련된 연구가 활발히 진행되고 있다. 컴포넌트는 다양한 정의가 존재하지만, 대체로 재사용 가능하며 의미있는 동작을 지닌 객체나 그러한 객체의 모임' 이라고 정의할 수 있다. 본 논문에서는 재사용을 지원하는 방법에 관해 논하였다. 소프트웨어 재사용 기술은 재사용 가능한 자원을 만들거나 사용하는 과정 자체에 관한 연구와 이를 지원하는 도구나 기법을 연구하는 부분으로 나뉘어 지는데 여기서는 재사용 프로세스를 지원하는 tool에 중점을 두었다. The cause of software development crisis that because lager and lager. Development of program add many relative functions to it whenever they develop a new version. Few users use these function. For this point of view, a reusability and supplying object-oriented technique, the study related with component is processing actively. The component has many definitions, however it is defined that generally, 'objects or the set of objects with reuseable and meaning action'. In this paper, we describe methodology of supporting reusability. Software reuseable technique is deviled two fields. One is the study processing of making and reuseable resource, another is that of tool or technique for this. We will mention the tool for supporting reuseable process later.

          Die spacer의 두께에 따른 복합레진 inlay의 치은 변연부 미세누출 및 접착양태에 관한 연구

          홍찬의,박태일,신동훈 大韓齒科保存學會 1995 Restorative Dentistry & Endodontics Vol.20 No.1

          AbstractThis experiment was performed to observe the adhesion pattern and microleakage in the gingival margin according to variation in the resin cement thickness which results from thickness of Die spacer, which is considered to effect the adaptability of the composite resin inlays. Clearfil CR inlays were fabricated on stone models with CR Sep applicated once and Nice fit twice, 4 times, and 6 times each. After 2nd curing within the CRC-100 oven, CR inlays were cemented with CR inlay cement. Dye (2% methylene blue) penetration and adhesion pattern were evaluated after sectioning of gingival margin into 3 pieces.The results were as follows ; 1. The thickness of resin cement showed unevenchanging pattern with that of die spacer, namely, it was increased until 4 times' application of Nice-Fit but was decreased with 6 times' application of that. 2. The degree of dye penetration wasn't affected by cement thickness within a limited value. 3. Most of dye penetration was shown through the interface between cement and enamel rather than the interface between cement and CR inlay. This shows that the affinity of resin cement for CR inlay was superior to the adhesive strength with tooth structure. 4. No gap was found at the interface between enamel and cement but some showed separa- tion between dentin and cement. It is concidered that the contraction force of cement was less than the bond strength with the enamel. 5. Lots of voids were found in the CR inlay and resin cement. There was a pooling tendency of bonding agent and cement in the axiogingival line angle portion. 6. In some specimens, cracks were shown in enamel margin. From this it could be conside- red that cavity preparation and surface treatment weakened the tooth structure.

        • 댄스스포츠가 노인들의 정서에 미치는 영향

          김의영,가경환,김태일 한국스포츠리서치 2001 한국 스포츠 리서치 Vol.12 No.4

          Through the study of psychological effects that the dance sports have on elderly, the purpose of this research is to find out ways to develop this field and activate it. It's based on the outcomes of an experiment that observed the changes in behavior of people who participated in it. The participants of this project are made up of total of 79 people who attend Chunhodong Bondang School for senior citizens located in Gyogu, Seoul and Nambu Senior Welfare Center in Bucheon, Kyungki Province and the students who are registered in for basic dance sports class. First, the analysis show that after taking the dancing sports program, the level of satisfaction in life increased up to 0.34, scoring t=7.69 at p<.05. Secondly, the tendency of pessimism decreased to 0.288 in average after the program, and also showing fall in t=6.56 at p<.05. Thirdly, the results showed that the people were happier after the program, judging from the rise up to 0.37 and t=5.28 at p<.05. Fourthly, the sense of alienation and solitude dropped to 0.55 and t=7.29 at p<.05 after the program. Fifthly, they became more relaxed in life than before and this is backed up by the increment of 0.396 and t=5.86 at p<.05. Lastly, people testified that they were in better conditions following the program and the results show that the average went up to 0.324 and t=4.61 at p<.05. From the results, one can conclude that the dance sports program have positive effects on the older generation and that it has actually improved their mental health as well as physical health and lifestyle.

        • 2 파라메터법에 의한 탄소성 파괴확률 예측수법

          김태식,윤한용,임명환,정의정 국립7개대학공동논문집간행위원회 2003 공업기술연구 Vol.3 No.-

          Many researchers have made a lot of progress in studying the evaluation of fracture probability of brittle materials. However, studies of fracture probability for elastic-plasticity have not been made yet. An evaluation method for fracture probability which is grafted onto a 2-parameter criterion and statistical probability analysis is not only introduced in this study, but also applied to the simple 2-dimensional model and carbon steel piping to evaluate the effect of statistical variables.

        • 담관 결찰 시 혈장 빌리루빈 농도와 GPT 활성도의 ICG 농도에 대한 상관관계

          배진우,이태의 건국대학교 의과학연구소 1998 건국의과학학술지 Vol.8 No.-

          Plasma clearance rate of indocyanine green (ICG) is the most important parameter to evaluate the hepatic reserve function for liver resection. To study the relationship between ICG concentration and bilirubin concentration or GPT activity in plasma, we determined these parameters before and after the ligation of bile duct. we ligated the bile duct of rats to induce hyperbilirubinemia and high GPT activity. Before and after the ligation (one day. three days. or fourteen days). we sampled 0.5 ml blood from portal vein to determine the concentration of bilirubin and GPT activity. After removing the ligation. we injected indocyanine green (0.5 mg/kg, 0.5 mg/ml) for 30 seconds through portal vein and sampled 0.5 ml of blood from the abdominal vein to determine ICG concentration after 15 minutes. From these data, we calculated the correlation coefficient. We calculated statistical significance of these parameters of different days after the ligation and the significance between two correlation coefficients. We confirmed the linearity too. All of these parameters were significantly higher than those before ligation(p<0.05). However GPT activity showed peaks after one day, while the concentration of bilirubin and ICG showed peaks after 3 days. The correlation coefficient was 0.884 between the concentration of ICG and bilirubin, but 0.721 between the concentration of ICG and GPT activity. These correlation showed significant linearity with p<0.001 and significant difference with p<0.05. These results suggest that ICG clearance can be negatively influenced by bilirubin concentration more than by GPT activity in the plasma. Therefore, care should be taken in determining the hepatic reserve function by ICG clearance rate for patients with hyperbilirubinemia.
