The purpose of this study was to suggest menu pricing strategy based on understanding about customer perceived value of products and services. The technique known as PSM (Price Sensitivity Measurement) was used for analysis of price sensitivity for 3 menu items of a family restaurant in Seoul. A questionnaire was developed through literature review and modified after pilot test. Questionnaires for the main survey were distributed to 250 customers on their visit to the restaurant, and a total of 138 questionnaires were used for analysis (55.2%). The statistical analysis of price sensitivity was conducted using PSM, and descriptive analyses were conducted using SPSS Win (12.0). The main results of this study were as follows: the price sensitivity of beef tenderloin steak was higher than two other menus and the stress range of teriyaki chicken was almost 0, that is, the price sensitivity of teriyaki chicken was very low. Present menu prices of 3 menu items were within the range of acceptable prices, but had some distances from the optimal pricing point. From the result of this study, it was concluded that price adjustment or price promotion strategy would be effective for increase in sales of beef tenderloin steak, and marketing strategies to enhance consumers' perceptions of value should be conducted for all menu items by situations. Overall, PSM technique could be a helpful tool for researchers and managers of foodservice organizations to understand how consumers' perceptions of value are affected by the interaction of price and quality.

With large corporations entering into the foodservice market, competitions among those foodservice providers became intense, leading to differentiated quality services in terms of portioning out the meal, its portion and waiting time, not to mention food quality. The purpose of providing foodservice is to satisfy its customers, to secure optimum level of profits, and attain continuous quality improvement. To have such purpose attained, all other factors affecting the foodservice should be allowed to play a role. The intensity of the work performed by the employees should be maintained at a steady level and systematically controlled. 'Service First’ principles upholding that customer satisfaction comes from good service should be applied at all times; customer satisfaction comes from the satisfaction of the employees. Customer satisfaction through good service will contribute to an increase in revenue which we get by subtracting operating expenses from the total sales, as it will lead to concluding a long-term supply contract or renewing the existing contract. To keep the operating expenses to the minimum level, it is important to effectively perform the cost control. Since personnel expenses occupy a large portion of the operating expenses, it is imperative to effectively control the labor costs. For this reason, this study will present an effective program for disposition of men with a large organization being centered around, where the number of people served at the mess hall varies greatly depending on a day of the week and a mealtime of the day.

The European Union (EU) is the world's third largest producer of beef. This contributes to the economy, rural development, social life, culture and gastronomy of Europe. The diversity of breeds, animal types (cows, bulls, steers, heifers) and farming systems (intensive, extensive on permanent or temporary pastures, mixed, breeders, feeders, etc) is a strength, and a weakness as the industry is often fragmented and poorly connected. There are also societal concerns regarding animal welfare and environmental issues, despite some positive environmental impacts of farming systems. The EU is amongst the most efficient for beef production as demonstrated by a relative low production of greenhouse gases. Due to regional differences in terms of climate, pasture availability, livestock practices and farms characteristics, productivity and incomes of beef producers vary widely across regions, being among the lowest of the agricultural systems. The beef industry is facing unprecedented challenges related to animal welfare, environmental impact, origin, authenticity, nutritional benefits and eating quality of beef. These may affect the whole industry, especially its farmers. It is therefore essential to bring the beef industry together to spread best practice and better exploit research to maintain and develop an economically viable and sustainable beef industry. Meeting consumers' expectations may be achieved by a better prediction of beef palatability using a modelling approach, such as in Australia. There is a need for accurate information and dissemination on the benefits and issues of beef for human health and for environmental impact. A better objective description of goods and services derived from livestock farming is also required. Putting into practice "agroecology" and organic farming principles are other potential avenues for the future. Different future scenarios can be written depending on the major driving forces, notably meat consumption, climate change, environmental policies and future organization of the supply chain.

Objective : In Oriental medicine, the concept of Preventive Treatment Disease(治未病, PTD) is intended to actively deal with changes in modern disease patterns due to increase in chronic diseases. In China, preventive health service program based on PTD Theory are being carried out aimed at improving and/or preventing people's health. Method : For the introduction of PTD program based preventive service in Korea for the promotion of people's health, I would like to consider its possibility by reviewing the PTD program being conducted in China. Results : China's preventive health service programs based on PTD Theory started in 2008 for the purpose of promoting people's health and reducing medical expenses by providing medical services tailored to individuals. Regarding the effects of PTD program based preventive health service, improvement of discomforting symptoms comprised 73.04% of responses. As to service items, health guidance, Traditional Chinese Medicinal diagnosis, and preparation of health records were answered as being important. The importance of food and internal medicines for preventing and/or curing PTD Theory are also recognized. Also, as to satisfaction level, 90.64% responded as being satisfied in the order of the level of service providers, their attitudes, service processes, items, costs, and environments. Conclusion : As shown above, according to assessments on China's PTD programs, the PTD Theory is being applied to actual public health programs with highly effective results. Hence, it can be seen that such attempt could also be implemented in Korea as part of a scheme for promoting health by means of Korean medicine health promotion programs. However, further researches into concrete implementation schemes will have to be developed in the future as medical systems are different in Korea from in China.

Rodents are well-known reservoirs and vectors of many emerging and re-emerging infectious diseases, but little is known about their role in zoonotic disease transmission in Bhutan. In this study, a cross-sectional investigation of zoonotic disease pathogens in rodents was performed in Chukha district, Bhutan, where a high incidence of scrub typhus and cases of acute undifferentiated febrile illness had been reported in people during the preceding 4-6 months. Twelve rodents were trapped alive using wire-mesh traps. Following euthanasia, liver and kidney tissues were removed and tested using PCR for Orientia tsutsugamushi and other bacterial and rickettsial pathogens causing bartonellosis, borreliosis, human monocytic ehrlichiosis, human granulocytic anaplasmosis, leptospirosis, and rickettsiosis. A phylogenetic analysis was performed on all rodent species captured and pathogens detected. Four out of the 12 rodents (33.3%) tested positive by PCR for zoonotic pathogens. Anaplasma phagocytophilum, Bartonella grahamii, and B. queenslandensis were identified for the first time in Bhutan. Leptospira interrogans was also detected for the first time from rodents in Bhutan. The findings demonstrate the presence of these zoonotic pathogens in rodents in Bhutan, which may pose a risk of disease transmission to humans.

Eutrophication processes of aquatic environment are strictly correlated with the concentration levels of nitrogen, phosphorous, organic matter and biological parameters such as phytoplankton and chlorophylla (Tremel, 1996; Burns et al., 1997; Young et al. 1999; Wei et al.,2000). Accordingly, the monitoring and evaluation of these factors will provide useful information about the health of aquatic ecosystem. However, the traditional types of auqatic chemistry analysis and ecological monitoring of phytoplankton are time-consuming, costly, and further resulting in secondary pollution due to the use of reagents. NIR (near-infrared) spectroscopy, as a rapid, non-destructive, little sample preparation and reagents-free technology (Hildrum et al., 1992), has been extensively applied to the characterization of food (Osborne and Fearn, 1988), pharmaceutical (Morisseau and Rhodes, 1995) and textile materials (Clove et al.,2000). Currently, NIR technology has been used indirectly in inferring lake water chemistry by two approaches, suspended (Malley et al., 1996) or seston (Dabakk et al., 1999), and sediments (Korsman et al., 1992; Malley et al., 1999). In addition, the evaluation of trophic state and the identification of the key factors contributed to the trophication are the key step to restore the damaged aquatic environment. Moreover, an understanding of the factors, which regulate the algal proliferation, is crucial to the successful management of aquatic ecosystem. In the paper, NIR technology will be used to study the environmental factors affecting the algal proliferation in combination with the trophic state index and diversity index. This novel developed system can be applied in monitoring and evaluating allopathic water environment and provide real time information services for the aquatic environment management.

Over the past few decades, the proportion of elderly people in Korea has been rapidly increasing. In particular, rural areas are experiencing aging of communities more rapidly compared to urban areas. However, public policy for the elderly does not respond to the needs of rural elderly. To distribute health care resources equitably, it is necessary to gather reliable information on the health status of the elderly. The purpose of this study is to explore factors affecting Korean elderly people's ADL functional status. The data sources are from 2004 Elderly Living Condition Survey. The Analysis sample consists of 3,278 cases. Analysis results show that there is a significant residential variability in education, monthly stipend, living arrangement, subjective health status, regular food in-take, and regular exercise. Logistic regression analysis results also show that 'cognitive ability'(exp(B)=6.603), 'subjective health status'(exp(B)=4.576), 'age'(exp(B)=2.610), and 'living arrangement'(exp(B)=.589) are factors affecting ADLs. Namely, when a respondent's cognitive ability is limited, subjective health status is poor, or if their age is over 75, the probability of having a limited ADL has been 6.6 times, 4.6 times, and 2.6 times higher than otherwise. Among these variables, cognitive ability was the best explanation. In contrast, respondents who live with a spouse or adult children have a lower probability of having limited ADL compared with those who live alone. Considering that the most critical criteria in determining eligibility for social welfare services is ADLs, the development of appropriate ADL assessment tools is in an urgent need. Without the accurate assessment on ADLs, particularly on rural as well as the urban elderly, it seems to be hard to achieve effectiveness in the health care policy for the elderly.

It is the actual state of the medical society in our country that many graduates of medical schools want to be clinicians, and accordingly Korea's medical situation is relatively too focused on curative medicine. However, this situation is changing due to several factors including a growing number of doctors, inappropriate regulations for medical fees, changes in social status of doctors themselves, and excessive competition between doctors. Furthermore, we expect more advances in medical field of Korea since Korean government started to attach great importance to sciences and produced policies to support sciences, and as a result, more and more interest and effort in the fields of basic research including preventive medicine is being attached especially by young doctors as compared against the past. However, decline of clinical medicine fields doesn't always mean bright future for the field of preventive medicine. True future is possible and meaningful only when we prepare for it by ourselves. In other words, as the promising future is closed to one who spares no effort, we shouldn't fear to oppose unknown challenges and simultaneously need to support colleagues who bear such a positive mind. It is the most important thing for our preventive medicine doctors to evaluate the past and the present of preventive medicine and to foster a prospective mind to prepare for the future of preventive medicine. I set forth my several views according to directions for the development of preventive medicine which we already discussed and publicized in the academic circle of preventive medicine. Those directions are recommendation of clinical preventive medicine, promotion of preventive medicine specialty, fostering the next generations, improving the quality of genetic epidemiologic study, participation in control of environmental pollution and food safety, contribution to chronic disease control, and preparation to role in medical services for unified Korea.
