김시남 부산여자대학 1986 釜山女子專門大學 論文集 Vol.8 No.-
We argue that a task - centered, an agent - centered and a cognition - oriented perspective are all needed for providing intelligent assistence in distributed office environments. We present the architecture for a system called OFFICE that combines these three perspectives. We illustrate this architecture through an example.

WT에 의한 디지털 INTEGRAL-CYCLE 電力制御의 解析
安斗守,金時男,李在春 成均館大學校 1983 論文集 Vol.33 No.-
A feedback controlled digital circuit is discussed with provides integral-cycle thyristor or triac control of AC power in RL loads. The circuit deals with compensating method for adjusting the firing angle of the thyristor or triac to eleminate the undesirable DC component in current of RL load. and then it shows how provides the optimum time distribution of the conducting half-cycle with in control period for the minimum of output ripple. Evaluation of the steady-state response for a simulated RL load system due to a constant digital control input is analyzed by application of Walsh transforms. Numerical example illustrates how Walsh transforms may be used to analysis the steady-state response of a system with 3-bit pararell binary input.

모듈러 공법 기반 강교 공급사슬 관리를 위한 시뮬레이션 모형 개발
이재일,정은지,김시남,정근채,Lee, Jaeil,Jeong, Eunji,Kim, Sinam,Jeong, Keunchae 한국건설관리학회 2022 한국건설관리학회 논문집 Vol.23 No.2
본 연구에서는 모듈러 공법 기반 강교 건설공사에 대해 공급사슬 관리를 위한 시뮬레이션 모형을 개발한다. 이를 위해, 우선 강교 건설에 대한 공장 제작/현장 시공 체계 자료를 수집한 후, 이를 바탕으로 공급사슬, 개체, 자원, 공정 등을 정의하였다. 이후, Arena 소프트웨어를 이용하여 데이터, 플로차트, 애니메이션 모듈을 작성함으로써 강교 공급사슬 시뮬레이션 모형을 개발하였다. 마지막으로, 개발된 모형의 논리성 검증과 유효성 확인을 위한 애니메이션 검증, 극한 조건 검증, 평균값 확인, 리틀의 법칙 확인, 사례 실적값 확인 등의 방법론을 이용하여 모형의 타당성을 검토하였다. 검토 결과, 개발된 시뮬레이션 모형은 논리적 오류 없이 강교 공급사슬의 공정과 특성을 적합하게 표현하며, 분석 대상 공급사슬에 대한 정확한 성능평가척도 예측치를 제공하였다. 향후, 본 연구에서 개발된 시뮬레이션 모형은 강교 공급사슬 체계를 최적으로 운영하기 위한 관리기법을 개발함에 있어 성능 평가 플랫폼으로서의 역할을 충실히 수행할 수 있을 것이다. In this study, we develop a simulation model for Supply Chain Management (SCM) of modular construction based steel bridge. To this end, first, Factory Production/Site Construction system data for the steel bridge construction were collected, and supply chain, entities, resources, processes were defined based on the collected data. After that, a steel bridge supply chain simulation model was developed by creating data, flowchart, and animation modules using Arena software. Finally, verification and validation of the model were performed by using animation check, extreme condition check, average value test, Little' s law test, and actual case value test. As a result, the developed simulation model appropriately expressed the processes and characteristics of the steel bridge supply chain without any logical errors, and provided accurate performance evaluation values for the target system. In the future, we expect that the model will faithfully play a role as a performance evaluation platform in developing management techniques for optimally operating the steel bridge supply chain.

흰쥐 피부의 창상 치유에 관한 광학현며경 및 전자현며경적 관찰
김영호 ( Young Ho Kim ),김시남 ( Si Nam Kim ) 대한임상검사과학회 1998 대한임상검사과학회지(KJCLS) Vol.30 No.3
The purpose of this study is to investigate the process of the wound healing and the morphologic mechanism of the scar formation We made primary and secondary wounds in the back of Sprague-Dawley rats. The Wounds were harvested at first day, third day, fifth day, seventh day, fourteenth day and twenty eighth day. The specimens were taken form primary and secondary wound sites and processed for light microscopy and electron microscopy. Generally, secondary wounds showed more prominant contraction and longer tome required for complete healing than primary wounds. Light microscopically, inflarrnnatory reaction was more predominant and the granulation tissue was more abundant in the secondary wounds. Ultrastructurally, neutrophils began to appear at the first day after wound in both primary and secondary wounds. Myoftbroblasts appeared at fourteenth day in the cases of the primary and secondary wounds. Collagen bundles were observed on third day and more increased and thick in the secondary wound at second and fourth weeks. From this study, ``secondary wound showed more severe inflamatory reation, wound contraction and collagen deposition than primary wound We believe that primary wound process is necessary to prevent the complication and to minimize the scar tissue for successful wound healing.

Abnormalities of p53 gene are common in lung cancers and are associated with immunologically detectable p53 protein. p53 immunoreactivity is uncommon in normal cells but is frequently seen in neoplasia. Therefore, assessment of p53 expression may assist in the cytological diagnosis of malignancy. The usefulness of p53 immunostaining as a marker of malignancy in the cytological analysis of bronchial brush specimens from the patients with lung cancers was investigated in this study. A total of 71 bronchial brush samples submitted for cytologic diagnosis were immunostained with D07, a monoclonal antibody to recombinant p53 protein. Resultant p53 data were correlated with cytologic diagnosis and clinical information. Of the 17 smears with a benign cytodiagnosis, all were p53 negative. Of the 40 cases with a malignant cytodiagnosis (histologically confirmed), 35 were p53 positive and 5 were negative. Of the 14 cases that were cytologically suspicious but nondiagnostic for malignancy, 11 were p53 positive, 9 of which were subsequently proved to be malignant by histologic examination, and the remaining 2 cases were tuberculosis clinically. Forty four of 51 histologically confirmed lung carcinomas were p53 positive, including 25 of 28 squamous cell carcinomas, 13 of 17 small cell carcinomas, 3 of 3 adenocarcinomas, and 3 of 3 large cell undifferentiated carcinomas. These results suggest that p53 immunostaining could be of value as a marker of malignancy in the cytologic examination of bronchial brush specimens. Furthermore, we have shown the possible clinical utility of p53 immunostaining in cytopathological diagnosis, that is, as a valuable adjunct to morphological assessment in the analysis of cytopathologically suspicious cases.
