This study was carried out to examine information regarding usage of health improving agents and health status of male workers in the Chonnam Yeosu industrial area. We obtained data by means of a questionnaire from 329 men. Of the subjects 44.7% were in their forties, high school education was 43.0%, married was 83.0% and $1,500{\sim}3,000$ thousand won in monthly income was 35.8%. Average height and weight of the subjects was $171.8{\pm}5.4 cm$ and $70.5{\pm}8.1 kg$. Average BMI was $23.8{\pm}2.2$. Drinking rate of respondents was 85.5%, the drinking rate of daily workers was significantly higher than rotation workers (p < 0.05). Rotation workers exercised more regularly than daily workers (p < 0.001). Subjective symptoms of the subjects always had eye problems (11.7%), shoulder aches (5.8%), ache in one's empty stomach (4.7%) in decreasing order. 21.4% of the subjects had a disease, and liver disease was the highest in the subjects; the second was cardio-vascular disease. Interval of health food intake was highly irregular (62.7% of respondents), and keeping healthy was the main motivation fur the usage of health foods. Health improving agents included oriental medicine, animal protein based restorative foods, nutrition supplements, health supplements, and natural foods. 33.3% of the subjects took health supplements, nutrition supplements (29.1%), oriental medicine (20.6%), natural foods (16.7%) and animal protein based restorative foods (3.9%), in respective order. Health improving agents were consumed higher in liver disease than other diseases. This study suggests that nutritional education and monitoring should be implemented for industrial workers to prevent life-habit diseases and to keep proper self-management of health status under special environments.

축산환경개선용 미생물 제품 중 시장점유율을 기준으로 상위제품 A, B,하위 제품 E, F와 현재 개발완료 되어진 C, D를 선정하여 생균수 측정과, 사료첨가용으로 사용이 금지된 항생제에 대한 내성 테스트를 실시하였다. 생균수 측정 결과 상위 점유율의 A, B사 제품은 표기상의 생균수와 일치하였으나, 하위 점유율을 차지하고 있는 E제품의 경우 함유균주나 효능에 대한 정보를 제공하고 않고 있을뿐더러 F사의 제품은 균수가 적게 측정되어 실제 표기사항과 일치하지 않았다. 항생제 내성실험결과 점유율에 따른 상관관계는 없었으나, B사를 제외한 제품의 대부분에서 내성균이 존재함을 확인하였다. Lincosimides 계열의 Lincomycicne과 Clindamycin의 경우 B사를 제외한 제품에서 내성균이 존재하였다. Penicillins 계열의 Amoxicillin, Ampicillin, Penicillin 및 Macrolide 계열의 Erythromycin 항생제는 B사와 E를 제외한 제품에서 내성균이 존재함을 확인하였다. Quinoline계열 Norploxacin 또한 B사와 E사를 제외한 제품에서 내성균을 보였으며 Neomycin의 항생제 또한 유사한 내성분포 결과를 나타내었다. Neomycin과 같은 Aminiglycosides계열의 Gentamycin, Streptomycin은 B사제품을 제외한 제품에서 내성을 나타내었다. 마지막으로 내성-균으로 사용 금지된 Tetracycline계열의 Oxytetracyclin은 12가지 항생제중 가장 높은 비율의 감수성을 나타내었으나 B, E사를 제외한 제품에서 내성균의 존재를 확인하였다. 실험결과 사용 금지된 항생제 품목임에도 불구하고 많은 제품에서 때 성균이 존재하였으며, 이에 따라 환경개선제 특성의 정확한 표기와 체계적인 유통 체계와 검증 과정이 필요하다고 사료된다.

An effective paging strategy is essential for improving the utility of radio channels. This paper proposes a two-step paging strategy which involves using base station paging agents to page a single cell at each paging. An analytical model is used to evaluate the performance of the proposed strategy. The proposed strategy is compared with the traditional simultaneous paging strategy and a recent proposal using the base station paging agents. The numerical results showed that the proposed strategy proficiently reduces paging cost on radio channels compared with other paging strategies.

It is expected that marketing environment of the hotel industry will change much this year. Hotels should make strategic marketing activities to cope with the rapid change of the environment positively. With the case study of marketing activities for American market of "L" Hotel, a deluxe hotel in Seoul, this study is to present the ways of improving marketing activities of a tourist hotel. U.S.A market has been emerging as the most important market in deluxe hotels with strong value of U.S. dollar currency. To get more Ameriean staying guests. hotels had better make effortis in American market as follow. First, hotels should select corporate market as main target market in U.S.A market. Second, hotels should make preferred corporate rate contracts with corporate travel departments of corporate accounts as their house agents Third, hotels should recognize Global Distribution System as major eservation network in U.S.A Fourth, hotels should advertise effectively in G.D.S in order that agents may reserve the hotel with its visual information. Fifth, hotels had better make the most use of three branch offices of K.N.T.O and sale offices of their affiliated reservation system to get useful information on corporates and travel agents.el agents.

Korean people use a lot of herbal agents for medical purposes, such as curing diseases, improving health state, but some of the herbal agents have toxic side effects. In terms of toxicology, herbal agents classified into 3 categories generally nontoxic, potentially toxic and toxic. But, there are few studies about the mechanisms and clinical features of intoxication of herbal agents. So detoxification or initial treatment of these agents is very difficult to clinicians in hospital. Authors experienced an uncommon case of intoxication after Arisaematis Rhizoma Ingestion. We report this case with review of Arisaematis Rhizoma.

BPMS (Business Process Management Systems) is aninformation system that systematically supports designing, administrating, and improving the business processes. It can execute the business processes by assigning tasks to human or computer agents according to the predefined definitions of the processes. In this research we developed a task assignment algorithm that can maximize overall process efficiency under the limitation of agents' capacity. Since BPMS manipulates the formal and predictable business processes, we can analyze the processes using queuing theory to achieve overall process efficiency. We first transform the business processes into queuing network model in which the agents are considered as servers. After that, workloads of agents are calculated as server utilization and we can determine the task assignment policy by balancing the workloads. This will make the workloads of all agents be minimized, and the overall process efficiency is achieved in this way. Another application of the results can be capacity planning of agents in advance and business process optimization in reengineering context. We performed the simulation analysis to validate the results and also show the effectiveness of the algorithm by comparing with well known dispatching policies.

Sediment is a useful natural source but deteriorated continually by anthropogenic and industrial sources. Therefore, it is imperative to search a suitable method for improving or restoring sediment quality. Sediment has been tested to identify the effects of some external agents on a polluted area for 28 days. Chemical analysis and total viable counts (TVC) test have been conducted for 4 days interval to assess their performance. The analyses of chemical oxygen demand (COD), acid volatile sulfide (AVS), total phosphorous (T-P), total nitrogen (T-N) indicate that the chemical agents was more efficient to improve sediment quality whereas the microbial agent was more efficient for nutrient releasing from sediment. Oxygen releasing property of the chemical agent was thought to be providing with more congenial environment for the higher growth of the bacterial community than the direct application of microbial agents.

There is a growing tendency to consider organizational learning as a mechanism for improving organizations and the rate at which organizations learn becomes perceived as a source for attaining competitive advantage. The objective of this research is to present a two-phase(learning efficient, and learning-effective) organizational modeling methodology based on the cognitive-maps and agents concept, and to describe how the result of the modeling can be used in the organizational learning context.
