분산 환경하에서의 웹기반 시뮬레이션에 관한 연구

이영해 한국시뮬레이션학회 1998 한국시뮬레이션학회 논문지 Vol.7 No.2

This paper introduces the concept of web-based simulation and suggests the structure of web-based simulation which reduces the simulation run time and performs simulations in efficient way under distributed environments. Since its introducing in 1996, web-based simulation has been studied only with a tool of applet, but in this paper a method of server applications for client applets will be used. In server application, server transfers objects requested by clients such as simulation engines, reports, files. After each client connects to web-server, and then server allocates simulation modules to connected clients. These work magnify the transferring applets from server and simulation models which were made by clients. This paper also processes a structure for managing efficiently web-based simulation under distributed environment and steps in which clients connect, model, simulate with distributed structure, and programs of proposed structure.

심부진균증의 방사선학적 고찰

이영해 대한영상의학회 1977 대한영상의학회지 Vol.13 No.2

Total 23 cases of deep mycoses were reviewed on the clinical and radiographic findings, which were coafirmed pathologically at Yonsei Univ College of Medicine, Severence Hospital until 1976. Summary of these was as follows. 1) Aspergillosis: 11 cases. 1. Although one case among them was systemic aspergillosis, all 11 cases had pulmonary aspergillsis. 2. They occured most commonly in 3rd or 4th decade and its main complaints were intermittent hemoptysis for a long time or occasionally massive one for a few days. All cases were treated as pulmonary tuberculosis but the lesions showed poor response to anti-tuberculous medication. 3. Their chest X-ray films revealed irregular mottled infiltrate (6 cases) or collapse and massive, dense consolidation (2 cases). Among them, 7 cases showed various form of“air meniscus sign”suggesting fungus ball, which was able to be detectable on tomography. Another finding was diffuse pneumonic pattern in 2 cases, which was not able to be differen iated from other pathogegic origin pneumonia. 4. Nine cases were belonged to mycetoma form, 2 cases were primary aspergillosis and there is no hypersenitivity aspergillosis in these cases, if these cases were classified. 2) Cryptococcosis: 8 cases. 1. Among 8 cases, 5 cases were crytococcal meningitis, 5 cases of them were thought to be pulmonary crytococcosis, liver biopsy was positive in 4 cases and lymphnode biopsy in 4 cases, including 2 cases of systemic cryptococcosis. 2. It occured commonly at the 1st decade and their clinical findings were multiple lymphadenopathy, uncontrolled fever, meningeal irritation symptoms such as severe headache, vomiting or drowsy mental state, fulminant hepatitis, skin eruption, but chest symptom was not significant. 3. Pulmonary lesions revealed moderate hilar or mediastinal adenopathy in all 5 cases, and miliary or coarse interstitial nodules were scattered in entire lung with lymphadenopathy in 3 cases, which should be differenciated from milia y tuberculosis, sarcoidosis and lymphangitic pulmonary metastasis. 3) Actinomycosis: 2 cases. 1. Both of two cases with subcutaneous abscess were diagnosed as the actinomycotic infection. 2. In one, neighbouring rib showed localized sclerosis and minimal bony rarefaction suggesting chronic osteomyelitis. This radiologic or clinical manifestation of actinomycosis is smeewhat different form the literatures. 4) Mucormycosis: 1 cases 1. A 34 years old, in diabetic coma, was diagnosed as the pulmonary mucormycosis. 2. Pulmonary lesion showed segmental, dense pneumonic consolidation with abscess formation in Lt. lower lung, which was common features of pulmonary mucormycosis. 5) Candidiasis: 1 cases 1. A 19 years old patient was diagnosed as diffuse involvement of Candida infection, with pathologic lesions of lung entire gastrointestinal tract. 2. Pulmonary lesion showed hilar prominency and diffuse coarse disseminated interstitial nodules in both lung fields. 3. The lumen of distal esopha us was narrowed with irregular coarse mucosae with fine, multiple ulceration and minimal mucoasal mucosal thickening of duodenal bulb and ileocecal area was also evident.

시뮬레이션을 이용한 기어드모터 생산시스템 분석

이영해 한국시뮬레이션학회 1995 한국시뮬레이션학회 논문지 Vol.4 No.2

Simulation is generally used for the performance analysis and optimization of manufacturing systems. Therefore in this paper using the simulation techniques we obtain the information about the efficiency improvement and the optimization. Because simulation optimization method is subjected to the applied field and environment the general simulation optimization method does not exist. So we do not take the fixed optimization procedure but suggest the alternative one which is modified for applied field. This procedure supplies the optimized simulation information and helps improve the productivity of Geared-Motor assembly line. In order to optimize the manufacturing system we use two simulation languages, FACTOR/AIM and SLAMSYSTEM. The former gives the abundant output information. The latter gives the flexibility in simulation modeling.

노인장기요양인력의 지역 공급변화와 과제

이영해,김은경 중앙사회복지연구회 2023 사회와복지 Vol.5 No.1

This study was conducted to propose a stable manpower supply and demand plan to provide long-term care services by analyzing changes in the supply of elderly long-term care workers. The main research results and implications are as follows. First, the number of long-term care workers continues to increase significantly in accordance with the increase in demand. By type of manpower, the number of social workers, nursing assistants, and nursing assistants increased significantly in the same trend, but the increase of nurses, nutritionists, and physical(occupational) therapists was small, showing large differences by type of manpower. Second, there was a large gap in the increase in long-term care workers by city and province, and the gap by type of manpower by city and province was also large, raising concerns about a shortage of specific types of manpower depending on the region. Third, as a result of analyzing the increase in long-term care workers by city, county, and district, the total number of workers increased significantly in the order of district, city, and county, and the increase rate was in the order of city, district, and county. The increase in manpower in the county region and the rate of increase were low, raising concerns over manpower shortage. By type of manpower, while there was a large increase in cities and districts, the increase in counties was very small, raising concerns about manpower shortages. In the future, it is necessary to prepare a supply and demand management system based on detailed data on the supply and demand status of the elderly long-term care workers by type and to ensure an appropriate supply of manpower. 본 연구는 노인장기요양인력의 공급변화를 분석하여 장기요양서비스 제공을 위한 안정적인 인력수급 방안을 제안하기 위해서 수행되었다. 주요한 연구결과와 함의는 다음과 같다. 첫째, 장기요양인력은 수요증가에 따라 지속적으로 큰 폭으로 증가하고 있다. 인력종류별로는 사회복지사, 요양보호사, 간호조무사는 같은 추세로 크게 증가하고 있지만 간호사, 영양사, 물리(작업)치료사의 증가는 적어서 인력종류별 차이가 컸다. 둘째, 시도별로 장기요양인력 증가의 격차가 컸으며, 시도에 따라서 인력종류별 격차도 커서 지역에 따라서 특정 종류 인력 부족이 우려되었다. 셋째, 시군구별로 장기요양인력의 증가를 분석한 결과 전체인력수는 구 지역, 시 지역, 군 지역의 순으로 많이 증가하였고 증가율은 시 지역, 구 지역, 군 지역의 순이었다. 전체 인력의 군 지역 인력증가와 증가율이 낮아서 인력부족이 우려되었다. 인력종류별로도 시와 구 지역이 많이 증가하는 반면에 군 지역의 증가가 크게 적어서 인력부족이 우려되었다. 향후 노인장기요양인력 종류별의 수급현황에 대한 구체적인 데이터에 기반한 수급관리체계를 마련하고 적정한 인력공급이 이루어질 수 있도록 해야 할 것이다.

단일 실행 시뮬레이션 최적화를 위한 Reverse-Simulation 기법

이영해 한국시뮬레이션학회 1996 한국시뮬레이션학회 논문지 Vol.5 No.2

Simulation is commonly used to find the best values of decision variables for problems which defy analytical solutions. This objective is similar to that of optimization problems and thus, mathematical programming techniques may be applied to simulation. However, the application of mathematical programming techniques, e.g., the gradient methods, to simulation is compounded by the random nature of simulation responses and by the complexity of the statistical issues involved. In this paper, therefore, we explain the Reverse-Simulation method to optimize a simulation model in a single simulation run. First, we point the problem of the previous Reverse-Simulation method. Secondly, we propose the new algorithm to solve the previous method and show the efficiency of the proposed algorithm.
