With the changing consciousness of consumers, there has been an increasing interest in nature-friendly lifestyles and safety of food ingredients. Therefore, the LOHAS image, which has value in social health and sustainability, is expected to be a factor that helps restaurants establish differentiation strategies. This study examined the LOHAS image of restaurants on involvement and willingness to pay. The results were as follows. First, eco-friendly food ingredients and interiors among the LOHAS image factors of restaurants had a significant effect on involvement. Second, the perception of LOHAS in the LOHAS image factors of restaurants had a significant effect on involvement. These results may be due to the lack of a conceptual understanding of LOHAS among restaurant customers, who fail to properly grasp its meaning. Therefore, in order to promote the LOHAS image of restaurants to customers, it is necessary to consider presenting POPs or signs that will enable customers to understand the concept of LOHAS inside the restaurant. Third, consumers' involvement turned out to have a significant effect on their willingness to pay. Thus, it is necessary to imprint the image of a LOHAS restaurant using eco-friendly colors, sculptures, and agricultural products so that customers can perceive food ingredients or interior elements as eco-friendly.

Monitoring the pesticide residues in agricultural products is essential to protect consumers, obtain data for risk assessment, and ensure fair trade practices. We developed a multi-residue method for the analysis of 37 pesticides with different physico-chemical properties in agricultural products and analyzed the amount of pesticide residues on about 1,000 samples circulated in South Korea. The samples consisted of 26 different types of agricultural products selected at markets in 14 major cities; cereals (2 species), nuts (1 species) potatoes (1 species), beans (2 species), fruits (3 species), vegetables (16 species), and mushrooms (1 species). In this study, residual pesticides were detected in 23 samples (2.2%) and one sample was detected to be over maximum residue limits (MRLs, 0.1%) for pesticides in foods by the Korea food code. In leafy vegetables such as pepper leaves, radish leaves, cham-na-mul, shin-sun-cho, crown daisy, chwi-na-mul and citrus fruits such as kumquat, 8 kinds of pesticides were detected. Specially, diazinon were detected over MRLs and also, endosulfan, ethoprophos and phenthoate were detected frequently. Based on these results, we investigated the risk assesment from amount of residual pesticide, total %ADI was 1.262%, but the value has not effected on human health.

The purposes of this study were 1) to investigate the importance level on factors affecting the foodservice management contract perceived by the clients in the office building, government and public offices and manufacturing company in Seoul and Kyungi 2) to compare the perceived importance levels of the present contract and future contract 3) to compare the perceived importance levels of the competitive bid with those of the private contract. To collect the data on the perceived importance level on the affecting the foodservice management contract, the questionnaires were developed by the delphi technique and modified by the pilot test. The questionnaires consisted of 4 categories and 19 items on the factors affecting the foodservice management contract and the importance level on the factors were measured by 5-likert scale. From March 12 to April 13 in 2003, the self-administrative questionnaires were mailed to 280 clients. The questionnaires were responded from the 50 clients (respondent rate: 25％). On the factors affecting the present contract and the future contract, among the 4 categories (the appropriateness of foodservice operation plan, the evaluation of the foodservice company, sales ability, the conditions of the cost in the contract), the importance level of the appropriateness of foodservice operation plan was higher than those of the other categories. In the comparison of the perceived importance level between the present contract and the future contract, the importance level of 4 items (sanitation and safety management plan, menu management plan, service management plan, food cost per meal) in the future contract were significantly higher than those in the present contract (p＜.01, p＜.05, p＜.05, p＜.01). There were the significant differences between the private contract and competitive bid on the factors affecting the present contract in the 3 items, which were $\ulcorner$renewal plan for interior and environment$\lrcorner$, $\ulcorner$strategic alliance with the contractor$\lrcorner$, $\ulcorner$lobby of the foodservice company$\lrcorner$ (p＜.05, p＜.05, p＜.05). And on the factors affecting the future contract, there were significant differences in the 2 items, which were $\ulcorner$renewal plan for interior and environment$\lrcorner$and $\ulcorner$cost per meal$\lrcorner$in comparing the competitive bid and private contract (p＜.05, p＜.01). The clients perceived the appropriateness of foodservice operation plan was more important than the other categories in the future foodservice management contract. It was proposed that the foodservice management contract company should focus on the foodservice operation to satisfy the customers and clients in order to get more contract in the future.

Purpose: Diabetic complications are a major concern to manage progression of diabetes. Production of advanced glycation end products (AGEs) due to high blood glucose is one of the mechanisms leading to diabetic complications. Multiple pharmacologic AGE inhibitory agents are currently under development, but clinical applications are still limited due to safety issues. Thus, it is necessary to identify a safe anti-glycation agent. It is known that burdock roots have antioxidant, anti-inflammatory, and anti-cancer activities. The objective of the present study was to investigate the inhibitory role of burdock roots on the formation of high glucose-induced glycation of bovine serum albumin (BSA). Methods: In this study, glycation of BSA by glucose, galactose, or fructose at $37^{\circ}C$ for 3 weeks was assessed based on levels of ${\alpha}$-dicarbonyl compounds (early-stage glycation products), fructosamine (intermediate products of glycation), and fluorescent AGEs (late-stage glycation products). In order to compare the inhibitory actions of burdock root extract in AGE formation, aminoguanidine (AG), a pharmacological AGE inhibitor, was used as a positive control. Results: BSA glycation by glucose, fructose, and galatose was dose- and time-dependently produced. Burdock root extract at a concentration of 4 mg/mL almost completely inhibited glucose-induced BSA glycation. The results demonstrate that burdock root extract inhibited AGE formation with an $IC_{50}$ value of 1.534 mg/mL, and inhibitory activity was found to be more effective than the standard anti-glycation agent aminoguanidine. This study identified a novel function of burdock root as a potential anti-glycation agent. Conclusion: Our findings suggest that burdock root could be beneficial for preventing diabetic complications.

Recently, people are becoming fatter in most parts of the world. Obesity is regarded as an important risk factor to adversely affect the health of humans, associated with hypertension, hyperlipidemia, diabetes, and cardiovascular diseases. In the present study, therefore, we tested the short time efficiency and safety of Bangpoongtongsungsan as a drug to decrease body weight in subjects with obesity. A total 48 volunteers (24 man, 24 woman) with body mass index (BMI : weight in kg divided by square of height in meters) of $23㎏/m^2$ participated in clinical study for 12 weeks, from 2008, March 01 to 2008, Jun 30. The subjects was received a dietary supplement of 12 pieces hard capsules per day (4 pieces in one, 3 times in a day) during the clinical study. At the end of clinical study, body weight of subjects was significantly decreased from $72.21{\pm}11.44\;kg$ to $70.53{\pm}11.67\;kg$ (p<0.05). Waist circumferences of subjects were reduced $91.58{\pm}6.43\;cm$ to $85.25{\pm}7.70\;cm$ (p<0.05). Also, a BMI of subjects was significantly decreased $26.07{\pm}2.35\;kg/m^2$ to $25.63{\pm}2.63\;kg/m^2$ (p<0.05). Particularly, a decrease in body weight, waist circumferences, and BMI was more significant in woman than man. But, other biochemical levels including lipid and glucose in plasma had no changes at the end of clinical study. In conclusion, administration of Bangpoongtongsungsan in subjects with high body weight fat could inhibit obesity associated with a decrease in body weight, waist circumferences, and BMI.

To assess the safety of solar salts of Jeollanamdo province where most of Korean solar salts are produced, 433 samples of solar salts in total were collected and analyzed for their contents of sodium chloride and heavy metals (lead, cadmium, arsenic and mercury). Sodium chloride contents ranged from 80 to 85% in 63% of solar salts analyzed. Lead was not detected in 77% of solar salt samples and showed a value of below the maximum permissible limit (2 ppm) in other samples. Cadmium was not detected in most samples (78%), and the other samples where cadmium was detected showed a value far below the maximum permissible limit (0.5 ppm) except for three ones. Arsenic was detected in only four samples, but their concentrations were far below the permissible limit (0.1 ppm). Mercury was not detected in all samples. There were some differences between producing areas in the levels of sodium chloride and lead of solar salts, but the contents of cadmium, arsenic and mercury did not show significant regional differences. These results clearly indicate that solar salts produced from Jeollanamdo province are safe in the aspects of lead, cadmium, arsenic and mercury contents.

Objectives: This study was conducted to examine the preferences and needs of typical Korean females adults for food and nutrition information provided by the mass media. Methods: A total of 343 females (77 in their 20s, 85 in their 30s, 88 in their 40s and 93 in their 50s) residing in the Seoul/Gyeonggido area was surveyed on general characteristics, main sources of food and nutrition information and needs for sources and contents of nutrition information. Results: The survey showed that typical Korean females obtained knowledge of food and nutrition mainly through the Internet (30.4%) and broadcasting (29.0%). Typical Korean females were interested in 'dietary management for weight control' (21.9%), 'the prevention and treatment of disease' (20.0%), 'food safety' (16.8%), 'proper dietary habits' (14.6%), 'cookery' (11.8%), 'functional foods' (9.6%), 'restaurant details' (3.5%) and 'life-cycle-specific dietary guideline' (1.6%). Needs for food and nutrition program forms on TV were 'educational programs' (34.3%), 'documentaries' (20.8), 'expert lecture-style' (13.0%), 'entertainment programs' (11.9%), 'expert conversation' (11.4%), 'news-style' (4.6%) and 'public campaign advertisements' (4.0%). On the Internet, 38.6% of the respondents preferred to get information provided by food and nutrition-related institutions (38.6%) while 26.1% preferred webtoons for nutritional information. The favored forms in mobile applications were 'monitoring their diets' (29.5%), 'data-based texts information' (21.4%), 'experts feedback' (20.6%), 'communities' (15.1%) and 'games' (13.1%). The rates of the preference to obtain information from experts such as nutritionists and dietitians and doctorsor dietitian turned reporters increased markedly with older ages. Conclusions: Since the mass media is a main source of food and nutrition information for the general public, the effectiveness and accuracy of the information provided should be enhanced by taking the needs of the public into account. The quality of information should be improved by involving more nutrition experts.

The purpose of this study was closely to explore the guidance experiences of senior elementary teachers who have had over 30 years of teaching experiences in elementary school based on interpretive(or hermeneutic) inquiry. The entry research question was 'What are the guidance experiences of senior elementary teachers like?' Seven senior elementary teachers working for O elementary School in G city participated in this study voluntarily. Each participant was interviewed twice in a consecutive manner. 14 periods of interview were completed all together and each period took about 40-60 minutes. In conclusion, this study conceptualized the guidance experiences of the senior elementary teachers(participants) as follows: First, the concepts of guidance held by the participants were conceptualized as 1) supporting and caring activity helping students to lead joyful school life, 2) assisting activity helping students to grow on good basic life habits, 3) character building activity helping students to lead integrative growth. Second, the fields and contents of guidance held by the participants were conceptualized as basic life habits, manners, and health & safety. Interestingly, these concepts were evolved in connection with their personal, practical teaching experiences rather than in-service teacher education. Third, the guidance methods frequently used by the participants were co-work with parents, exemplary storytelling, counselling, and praise. The participants applied these methods differently according to the grade, individual difference, and school curriculum policy to some degree. Fourth, the participants have experienced a lot of struggles with students, teachers, and parents in doing their guidance practices throughout the whole teaching career. Their guidance experiences commonly shifted from more teacher-centered or authoritative to more student-centered or relational way as their teaching years accumulated. Interestingly, all the participants more or less lived as lifelong learners to create their own right space as senior teachers in today's competitive and challenging landscape. This study strongly suggests that responsible teacher education can playa great role of enabling senior teachers to cope with guidance issues successfully. Compared with the speedy social change, the teacher education in Korea had been so authoritative, provider-based, subject-based until recently and it have not met the needs and wants of the elementary teachers in field. This trend has significantly hindered them from catching up with the needs of the speedy social change in terms of contemporary guidance issues. This study is limited in that the data is solely collected based on interview. So, an observational research is strongly suggested in order to uncover the situated understanding of the guidance experiences of elementary senior teachers.

Firefighters performing disaster response activities such as Fire Suppression Rescue First Aid in fire are being exposed in various adverse factors, heat, smoke, toxic gases, emotional stress, biological toxic factors and physical overload by unnatural ergonomic posture required for firefighters. But so far, there is the study for this problem only separately. There is no study about comprehesive analysis of exposed adverse factors in fire-related disaster response activities and countermeasures. The purpose of this study is to contiribute to solving the health problems and prevention of accidents of firefighters by extracting hazardous agents in disaster such as fire and by proposing countermeasures. After analyzing circumstances such as fire-suppression, rescue first aid and life-environment, exposure factors of fire are derived and exposure status is suggested according to physical chemical biological psychological aspects. The countermeasure against the noise of the physical exposure factors are proposed. The countermeasures such as protective equipment and clean room in chemical factors, infection prevention education, vaccination and periodic check system in biological factors, PTSD alleviation booth and mentoring in psychological factors are proposed.

The East Asian Region has experienced remarkable economic growth and transformation of interurban networking over the past three decades, and urban competiti veness for a networking hub in this region has become a critical issue confronting cities. Competitiveness of the Seoul capital region for a networking hub in Northeast Asia is outstripped by other competing cities in East Asia, notwithstanding its geo-politically and geo-economically advantageous location in this region. In this paper, we aim to appraise the Seoul capital region's competitiveness in terms of logistics distribution, financial function and logistics distribution, financial function and agglomeration of transnational corporations (especially of RHOs and other managerial functions), and to advance the networking strategies of the region for a Northeast Asia hyb. As a result of analysis, we suggest that the Seoul capital region be developed as a Northeast Asian center for regional headquarters or leading global corporations and financial services for being a strategic nodal point in Northeast Asia in the 21st century. A recent survey shows that where to locate an RHQ is influenced by various factors, such as potential market and manufacturing site in the city's hinterland, quality of life, such things as culture, health, safety, education, a well-educated, English-speaking population, reliable air transport, state-of-the-art communications, and an active policy to offer foreign companies generous incentives. The Seoul capital region, which is located at a strategic nodal point advantageous as a springboard for its Northeast Asian hinterland, cannot meet the other conditions mentioned above. To overcome these drawbacks in attracting transnational capital and to create competitiveness as a strategic hub of RHQs in Northeast Asia, it is urgent to initiate a structural reform of the Korean economy, politics, and overall society, to minimize the regulation of FDI, and to provide various incentives for foreign investment. Moreover, we propose the construction of an 'International Business Town' in the Seoul capital region, as a medium to intermediate these strategies and to shape them in a spatial scale. The projected 'International Business Town(IBT)' will be a 'free city' open to international business in which liberal economic activities are guaranteed by special legislation and administration, infrastructures needed for international and improved accessibility to the airport are furnished, and the preference of foreign high-income investors for cultural and living environment are satisfactorily met. IBT is conspicuously differentiated from a raft of other cities' incentives in that it combines deregulation and incentive programs to attract the investment of transnational capital, with a spatial program of offering an urban environment preferred by the high-income investors for cultural and living environment are satisfactorily met. IBT is conspicuously differentiated from a raft of other cities' incentives in that it combines deregulation and incentive programs to attract the investment of transnational capita, with a spatial program of offering an urban environment preferred by the high-income and managerial class. Furthermore, it can be an excellent way of overcoming the xenophobia that has spread among the Korean population by concentrating foreign businesses and their lifestyles in a specific foreign businesses and their lifestyles in a specific zone. In conclusion, 'International Business Town', in line with other legislative and administrative incentive programs, will function as a driving force to make the Seoul capital regional more competitive as a regional business hub in Northeast Asia.
