The occupational health problems are the major issue in the modern industrial society. Especially the small scale industries have many hazardous factors and not any occupational health programs in itself. Fortunately. the government-funded subsidiary program was developed and carried out in the past six years in our country. The purposes of this study were to find out the actual condition of the occupational health personnel's accomplishments for the government-funded subsidiary program for small scale industries and to provide basic data for setting up more developed subsidiary occupational health program. Data were collected through 6 kinds of service records review. These service records were written by 3 occupational health personnels were attached to the one subject center of KIHA. were undertaken during March to December, 1997. at 95 small scale industries which were applied the government-funded subsidiary occupational health program. Results were as follows 1. Concerning 95 small scale industries showed characteristics of a typical small scale industry. 2. A doctor visited in industries total 190 times per year, average 19 industries per month, twice per year and industry. A hygienist visited in industries total 378 times per year, average 38 industries per month, four times per year and industry. A nurse visited in industries total 477 times per year. average 47 industries per month, 5 times per year and industry. 3. 3 occupational health personnels accomplished total 3,869 items. A doctor accomplished total 539 items per year, each time 3 items In an industry. A hygienist accomplished total 1.581 items per year, each time 4 items in an industry. A nurse accomplished total 1.749 items per year, each time 4 items in an industry. 4. The major contents of doctor's accomplishment were 'health consultation for suspicious worker with general & occupational disease', 'a check of the workplace & special health education', 'guidance of special medical examination in the second half of year', etc. The major contents of hygienist's accomplishment were 'pretest & guidance of planning for evaluation of working environment'. 'evaluation for ventilating facilities & suporting self inspection', 'guidance of MSDS recording & chemicals management', etc. The major contents of nurse's accamplishment were 'health counseling of general & special medical examination results'. 'health education of preventing occupational disease & health disorder'. 'guidance of subsidiary program planning', 'selecting & guidance of health monitor', etc. It was concluded that the occupaional health personnels implemented the subsidiary program according to the order of health management guide. The current health management guide of subsidiary occupational health program in which the fixed contents, visiting number & periods is not desirable. That guide is left the characteristics of small scale industries out of consideration. It is suggested that occupational health management guide should be developed according to the general & environmental characteristics of each small scale industry, and on the other hand, the more specific guide for each occupational health personnel should be developed.

We present a new approach to the analysis of mobile cellular communication systems under the environment of mixed platforms adopting a guard channel scheme. We assume general cell residence time distributions according to platform-types. Our system model is based on a heterogeneous M/G/c loss system with customer-dependent guard channels, where heterogeneous customers with different service time distributions have different numbers of their own guard channels. We develop the general formula of steady state probabilities for the heterogeneous M/G/c loss system with customer-dependent guard channels. The mean channel occupancy times of new and handoff calls are rigorously derived under a general setting. Finally, our numerical results show that the blocking probability and the forced termination probability are sensitive to the cell residence time distributions.

Tourist loyalty is created through good tourism service quality and the availability of tourism products. This study discussed the various attributes of tourism service quality, namely, tour agents, efficient personnel, accessible transportation, and information service quality. Whereas for tourism product availability attributes were varieties of product availability, wide selection of tour agents and tourist products, and wide variety of amenity services. As a general rule, the minimum is to have at least five times as many observations as the number of variables to be analyzed, and the more acceptable sample size would have a 10:1 ratio. A total of 424 questionnaires were returned, with 35 removed due to errors. Finally, 389 questionnaires respondents were used via accidental sampling method through the distribution of questionnaires to foreign tourists at Soekarno Hatta International Airport. In addition, AMOS 7.0 software is used to test models in confirmatory factor analysis (CFA) as well as hypothetical testing using structural equation modeling (SEM). The results showed that all hypotheses were accepted, except for the effect of tourism service quality on tourist loyalty in Indonesia. This research aims to contribute significantly to the existing knowledge of tourism, specifically from a foreign tourist perspective in Indonesia.

The characteristics of business organization of retailing in analyzed by principal components analysis, and the types with component in each district (city, county, ward) is analyzed by cluster analysis(Ward method). The data of 1979 were obtained from the statistics in the Census of Wholesale and Retail Trade published by the National Bureau of Statistics of Economic Planning Board, and that of 1991 were obtained from the statistics in the Report on Establishment Census (Vol.3 Wholesale and Retail Trade) published by the National Statistics Office. The following are resultant findings. 1. In Seoul metropolitan area, changes in the industrial composition of retailing with annual sales from, 1979 to 1991 show very higher composition rates of 'general merchandise stores' and 'retailing of personal transport equipment and gasoline service stations', but comparatively lower composition rates of 'retailing of food, beverages and tobacco', 'retailing of textiles, clothing, footwear and apparel accessaries', 'general retail trade, n.e.c.',and 'retailing of household fuel'. 2. The characteristics of business organization of retailing in Seoul metropolitan area presents the prevailence of small, personal business organization and especially larger employees of ordinary times. 3. Business components of retailing by principal components analysis in Seoul metropolitan area are follows: 1 All retaining industries are larger business scale. 2. Larger business take the 'retailing of taxtiles, clothing, footwear and apparel accessories', 'retailing of furniture, home furnishing and equipment', and 'retailing of jewellery and watches' is main characteristic legal organization and employees of ordinary times. 4. Types changes in business organization of retailing in Seoul metropolitan area represent legal organization and employees of ordinary times taking the 'retailing of textiles, clothing, footwear and apparel accessories', 'retailing of furniture, home furnishing and equipment',and 'retailing of jewellery and equipment', and 'retailing of jewellery and watches', and legal organization taking 'general retail trade, n.e.c.' in 1979. All retailing industries are changed into larger business scale, in 1991. These phenomena of business changes appeared southeastern regions in Kyunggi-do(province). And larger business scale taking the 'retailing of textiles, clothing, footwear and apparel accessories', 'retailing of jewellery and watches', and 'general retail trade, n.e.c.; are appeared in the legal organization in 1979. 'Retailing of personal transport equipment and gasoline service stations' are appeared in employees of ordinary times in 1991. These phenomena of business changes in appeared in eastern and northern regions in Kyunggi-do. 5. Changes in the business organization of retailing in Seoul metropolitan area is appeared in legal organization and employees of ordinary times for some industries in 1979, larger business scale of retailing and employees of ordinary times in 'retailing of personal transport equipment and gasoline service stations' are the characteristics in 1991.

In this paper, we consider multiple-class queueing systems in which the server starts a set-up as soon as the number of customers in the "start-up class" reaches threshold N. After the set-up the server starts his service. We obtain the Laplace-Stieltjes transform and the mean of the waiting times of each class of customers for FCFS and non-preemptive priority disciplines.

For an M/G/1 processor-sharing queue with batch arrivals, Avrachenkov et al. [1] conjectured that the conditional mean sojourn time is concave. However, Kim and Kim [5] showed that this conjecture is not true in general. In this paper, we show that this conjecture is true if the service times have a hyperexponential distribution.
