This paper is to analyze and provide some managerial requirements for the successful implementation of total productive maintenance system. It tries to identify determining factors for success and reasons for the failures of TPM, based on the research of a survey and an empirical study through the years in Korea. The findings are such that many companies have not been engaged in planning and control the maintenance cost and their maintenance activities are not organized systematically. However, many indicators show that the number of finns which try to introduce and implement TPM is getting increased. The successful implementation of TPM depends largely on how top management perceives TPM and how the firm responds In the changes of organization and of the role of workers to adapt this new concept of work. It is required that TPM is perceived as a means to achieve the firm's business objectives. It is recommended that each company constructs and develops its own model and procedures to drive the effort for TPM implementation.

본 연구는 장미농가의 생산효율성을 측정하고, 경영의 비효율성에 영향을 미치는 요인을 파악하기 위한 연구이다. SFA(Stochastic Frontier Analysis) 기법과 DEA(Data Envelopment Analysis) 기법을 사용하여 생산효율성을 측정하였으며, 효율성에 영향을 미치는 요인을 분석하기 위하여 Tobit 회귀 분석을 실시하였다. 먼저, SFA 방법을 통한 생산효율성은 88.4%으로 측정되었으며, DEA 방법에서 불변규모수익(CRS) 모형과 변동수익규모(VRS) 모형을 통해서는 생산효율성이 각각 78.5%와 85.2%로 측정되었다. 특히 두 가지 방법의 생산효율성 측정결과는 각 경영체의 효율성 순위를 동일하게 설명하고 있어 상호보완적이다. 다음으로 Tobit 분석 결과, 투입한 6개의 변수가 모두 효율성에 영향을 미치는 것으로 나타났으며, 종묘비와 제재료비는 (+) 부호를 나타냄과 동시에 회귀계수가 가장 크게 나타나 효율성에 미치는 영향력이 가장 큰 경영 항목으로 분석되었다. 이러한 결과는 장미농가는 종묘비와 제재료비의 투입을 증대시켜 더욱 높은 소득을 창출하는 방식으로 경영 효율성을 증대시켜야 함을 시사한다.

Many firms have applied flexible manufacturing systems as a means of increasing productivity, profitability, and quality. Therefore, the purpose of this paper is to develop the more efficient justification model through an analytical scoring model with the quantitative factors, flexibility factors, and safety factors under uncertainty. In this paper, the three factors for properly comparing and evaluating of flexible manufacturing systems are presented. Especially, this paper has emphasized the flexibility and safety factor; the one consists of organization assessment, process treatment function, products and products quantity, useful life assesment, and software function, the other presents risk assesment, Y2K problem, safety device analysis, total productive management system, safety management. Finally, a normalized scoring model by the new flexibility and safety factors can be used in real fields for flexible manufacturing systems project selection under uncertainty.

Changing concepts of health care, are stimulating the demand for health care, thereby orienting society to health care rights to such an extent that they are deemed as fundamental ones inalienable to man. Concomitantly, qualitative as well as quantative improvement is being sought in the nursing service field. Today, efforts are being made in various areas, especially to qualitatively improve nursing services. A second issue concerns proper staffing. It is important to study staffing, in as much as it continues to be the most persistent and critical problem facing hospital nursing administrators today. It involves quantity, quality, and utilization of nursing personnel. A great deal of attention has been focused on this problem since mid 1930's when nursing services began to be felt as an important segment of hospital operation representing the largest single item of hospital budgets. Traditionally, the determination and allocation of nursing personnel resources has relied heavily on gloval approaches which make use of fixed staff-to-patient ratios. It has long been recognized that these ratios are insensitive to variations between institutions and among individual patients. Therefore, the aim of this thesis is to point to the urgent need for the development of methodology and criteria suited to the reality of Korea. The present research selected one place, the W Christian Hospital, and was conducted over a period 10 days from January, and nurses who were them on duty in their unit. The total num-her of patients surveyed was 1,426 and that of 354. The research represents many variables affecting the direct patient care time using the result from the direct observation method, then using a calculation method to estimate the relationship between the patients care time and selected variables in the hospital setting. The amount of direct patient care time varies with many factors, such 89 the patients age. diagnosis and time in hospital. Differences are also found from hospital, clinic to clinic, ward to ward, and even shift to shift. In this research, the calculation method of estimating the required member of nursing staff is obtained by dividing the time of productive patient care activity(with the time of patient care observed), by the sum of the productive time that each the staff can supply, i.e., 360 minutes, which is obtained by deducting the time for personal activities. The results indicate a substantial difference between the time of productive patient care observed directing and the time of the productive patient care estimated using calculating method. If we know accurately the time of the direct patient care on a shift, there required number of staff members calculated if the proper method can be determinded should be able the time of the direct patient care be estimated by the patient classification system, but this research has shown this system to be in accurate in Korea. There are differences in the recommended time of productive patient care and the required number of nursing staff depending upon which method is used. The calculated result is not very accurate, so more research is needed on the patient classification system.

디지털 경제를 맞이하여 대부분 자산을 부동산에 투자하고 있어 향후 부동산 가격에 많은 관심을 보이고 있다. 다양한 변수들이 주택 등 부동산 시장에 영향을 미치고 있다. 그 중 대표적으로 세대주와 생산가능인구, 금리, 주가지수 등 4가지 변수들을 선정하여 어느 변수가 서울아파트 가격에 얼마나 통계적으로 유의하게 영향을 미치는지 살펴보았다. 본 연구는 실증적으로 서울아파트가격의 결정모형을 구축하는데 목적이 있다. 분석결과 주가지수만 서울아파트와 통계적으로 유의한 것으로 분석되었다. 세대주나 생산가능인구는 기존의 연구처럼 서울아파트와 방향성은 동일하지만 통계적으로 유의하지 않은 것으로 분석되었다. 독립변수 중에서 서울아파트 가격의 결정요인으로 주가지수만 주요 변수로 선정되었다. 본 연구결과 향후 주택 등 부동산시장의 예측하기 위해서는 주식시장의 전망이 선행되어야 할 것이다.

Because of the imminent market opening of livestock and poultry products, Korean poultry industry is faced an influx of contagious diseases from abroad. Due to the increasing trend of intensive and automatic poultry farming, the risks of catching various poultry epidemics are ever more increasing. For the prevention of poultry epidemics, the principles of biosecurity should be observed rather strictly. In addition, regular checking to confirm the presence or absence of latent diseases through serological test, post-mortem examination, and laboratory test, should be carried out routinely. Finally, all kinds of stress factors should be minimized to keep the flock healthy and productive, so that they can achieve their maximum genetic potential.
