The purpose of this research is to assess the geographical distribution of physicians and dentists and the degree of maldistribution of the physician. Data were obtained form the Korean Medical Association's report on physicians registry and census for 1990. To assess the degree of disparity in the rural-urban distribution of physician manpower and to identify changes in the distribution pattern, the Gini index of concentration was used. Major findings are as follows; 1. Urban-rural disparity in the distribution of physician manpower exists in all categories of manpower, i.e. physician, dentist, oriental medical doctor, general practitioner, medical specialist, practitioner, public health physician and public health dentist. Urban area which had 74.4% of nation's population, accounted for over 90% of all physician manpower. 2. In terms of the ration of physician manpower per 10, 000 population, in urban area, they were 8.2 physicians, 2.7 general practitioners, 5.5 specialists, 3.0 practitioners, 1.8 dentists and 1.3 oriental medical doctors. In rural area, the ratios were 1.4 physicians, 0.6 general practitioners, 0.9 specialists, 1.0 practitioners, 0.4 dentists and 0.4 oriental medical doctors. 3. Gini indicies computed to measure inequality of physician manpower distribution were 0. 3675 for physicians, 0.3372 for general practitioners, 0.3338 for specialists, 0.2263 for practitioners, 0.3132 for dentists and 0.3293 for oriental medical doctors. 4. Inspite of increase in the number of physician manpower, urban concentration of physician manpower intensified from 1980 to 1990. However, the Gini index for all physician manpower fell by 18.3~36.7% from 1980 to 1990, indicating more even distribution. 5. In rural area, the public health physicians and dentists had increased the ratios of physicians, general practitioners, practitioners and dentists per 10, 000 population remarkebly, and had decreased the Gini indicies of physicians, general practitioners, practitioners and dentists. Thus, public health physicians and dentists contributed to improve the distribution of physician manpower in rural area. Based on the results of this study, long-term and rational manpower policies should be developed to solve the problem of geographical maldistribution of physician manpower as well as short-term policy for inducing physicians to the rural areas.

성공적인 프로젝트 계획은 프로젝트를 개발하는데 요구되는 인력을 얼마나 정확히 추정하느냐에 달려있다. 이 정보들은 Putnam의 Rayleigh 모델이나 Phillai et al.의 Gamma 모델들로 부터 유도된다. 그러나 이들 모델들은 투입 인력이 지수적으로 계속적으로 증가하여 개발이 종료되는 시점에서 투입되는 인력이 절정에 도달하는 소프트웨어 생명주기 전체에 대한 인력분포를 대상으로 하고 있다. 그러나 실제 프로젝트에서는 대부분의 인력이 개발에 투입되고 단지 적은 규모의 인력만이 유지보수에 할당된다. 또한, 대표적인 개발 프로세스인 폭포수 모델이나 단일화된 프로세스도 개발단계만을 대상으로 하고 있다 이러한 개발환경에는 개발완료시점에서 절정에 도달하는 기존 인력분포 모델의 투입인력 분포 곡선을 적용할 수 없다 본 논문은 이러한 문제점을 해결하기 위해 개발단계에 적합한 인력분포 모델을 제시한다. 먼저, Putnam이 제시한 인력분포로부터 폭포수 모델의 개발단계 투입 인력 분포를 유도하고, 다음으로, 단일화된 프로세스에 대한 개발단계 투입인력 분포를 유도하였다. 두 프로세스 투입인력을 비교한 결과 개발 각 시점에 대한 투입인력의 양, 수행 업무 단계는 차이가 발생하지만 총 투입 인력분포는 유사한 형태를 나타내었다. 이 결과로부터 두 개발 프로세스 모두에 적용할 수 있는 단일화된 개발인력 분포 모델을 유도하였다.

노력 (인력)과 일정이 추정된 경우, 인력을 일정 시간대별로 효율적으로 배분하기는 매우 어렵다. 지금까지 Putnam의 Rayleigh 분포모델이 널리 적용되고 있다 이 분포는 프로젝트 전반부에서 인력이 집중적으로 투입되는 형태를 표현하고 있다. 그러나 실제 수행된 프로젝트의 대부분이 중반부나 후반부시점에서 인력이 집중적으로 투입되는 현상을 나타내 Rayleigh 분포를 적용할 수 없다. 따라서 본 논문은 인력을 효율적으로 배분하기 위한 모델을 제안한다. 먼저, 소프트웨어 개발 분야에서 제시하고 있는 전형적인 형태와 실제 수행 프로젝트들의 인력 프로파일 형태를 고찰하였다. 다음으로, 효율적인 인력 배분을 위해 인력 프로파일에 대한 윤곽을 그려 모델을 유도하는 방법을 제안하였다. 제안된 모델은 기존의 Rayleigh와 Gamma 모델보다 좋은 성능을 나타내었다. 제안된 모델을 적용할 경우 소프트웨어 개발계획단계에서 개발기간에 대한 투입될 인력을 적절히 배분하여 프로젝트를 성공적으로 관리할 수 있을 것이다.

성공적인 프로젝트 계획은 활용 가능한 일정과 더불어 프로젝트를 개발하는데 요구되는 인력을 얼마나 정확히 추정하느냐에 달려있다. 현존하는 소프트웨어 인력 추정 모델들은 생명주기 전반에 걸쳐 투입되는 총 인력과 단위시간당 소요되는 인력 분포를 제공한다. Putnam의 Rayleigh 모델이나 Phillai et al.의 Gamma 모델 모두 소프트웨어 개발이 종료되는 시점에서 투입되는 인력이 절정에 도달한다는 가정하에 모델을 제시하였다. 이는 개발완료시점까지 40%의 인력이 투입되며, 나머지 60%는 유지보수 단계에 투입됨을 의미한다. 그러나 Warburton은 실제 프로젝트는 대부분의 인력이 개발에 투입되고 설계가 종료된 시점에서 투입인력 규모가 절정에 도달하며, 유지보수에는 단지 적은 규모의 인력만이 소요됨을 관찰하였다. 따라서, 제안된 기존 모델들은 실제 프로젝트에 적용하는데 문제가 발생한다. 이러한 문제점을 해결하기 위해 본 논문은 투입인력 절정 시점 모수를 고려하지 않는 시그모이드 모델을 제시하였다. 제시된 모델을 실제 데이터에 적용하여 향상된 성능을 보였다 따라서 제안된 시그모이드 모델은 소프트웨어 개발주기 동안 투입되는 인력 분포를 추정하는데 있어서 Rayleigh나 Gamma 모델의 대안으로 적용이 가능하다.

The efficiency of fabrication (fab) operation is one of the key factors in order for a semiconductor manufacturing company to stay competitive. Optimization of manpower and forecasting manpower needs in a modern fab is an essential part of the future strategic planing and a very important to the operational efficiency. As the semiconductor manufacturing technology has entered the 8-inch wafer era, the complexity of fab operation increases with the increase of wafer size. The wafer handling method has evolved from manual mode in 6-inch wafer fab to semi-automated or fully automated factory in 8-inch and 12-inch wafer fab. The distribution of manpower requirement in each specialty varied as the trend of fab operation goes for downsizing manpower with automation and outsourcing maintenance work. This paper is to study the specialty distribution of manpower from the requirement in a typical 6-inch, 8-inch to 12-inch wafer fab. The human resource planning in today’s fab operation shall consider many factors, which include the stability of technical talents. This empirical study mainly focuses on the human resource planning, the manpower distribution of specialty structure and the forecast model of internal demand/supply in current semiconductor manufacturing company. Considering the market fluctuation with the demand of varied products and the advance in process technology, the study is to design a headcount forecast model based on current manpower planning for direct labour (DL) and indirect labour (IDL) in Taiwan’s fab. The model can be used to forecast the future manpower requirement on each specialty for the strategic planning of human resource to serve the development of the industry.

This paper dealt with the Korean manpower policy in science and technology, focusing on the contents and tools of the Special Act and its Master Plans. After briefly introducing the historical development of the Korean manpower policy from the 1960s to the present, it discussed and analyzed the Special Act and Plans from the framework of personnel development, distribution, utilization and infrastructure. Korea's science and technology manpower policy has focused on fostering and supplying manpower in line with the country's industrial growth strategy. In the early stage of industrial development during the 1960s and 1980s, government research institutes were direct and effective tools for nurturing S&T manpower. Since the 1990s, the importance of university research has increased. The government fostered graduate research manpower through the research-oriented university policy of the BK21 program. After the IMF financial crisis in 1997, the tendency of students to avoid careers in science and technology led to enacting the Special Act (2004) governing the field of S&T human resources. The Special Act has contributed to leveling up the university education system in science and engineering and sophisticated the policy to include entrepreneurship training, spin-off startups, industry-university cooperation, and offering degree programs. The Special Act and the regularly revised Master Plans have been essential tools in systematically managing the science and technology manpower policies of the Korean government.

In order to compare the geographical distribution of physician by level of medical care and specialty, a log linear model was applied to the annual registration data of the Korean Medical Association as of the end of December, 1991 which was supplemented from related institutions and adjusted with relevant sources. Those physicians in primary and secondary care institutions were not statistically significantly unevenly distributed by province-level catchment area. There were some differences in physician distribution among big cities, medium and small-sized cities, and counties; however, those physicians for primary care level were equitably distributed between cities and counties. Specialties for secondary care physicians were less evenly distributed in county areas than in city areas, and generalists are distributed more evenly in cities and counties than in big cities. There is a certain limitation due to underregistration in the annual physician registration to the Korean Medical Association; however, the geographical distribution of physicians has been improved quantitatively. It is strongly suggested that specialties and the level of medical care should be considered for further physician manpower studies.
