The purpose of this study is to analyze the mediating effect of career decision-making self-efficacy on the relation between the social support of professors and the career preparation behaviors of students who specialize in foodservice & culinary art. The participants of the study consisted of 250 students from the departments related to foodservice and culinary art of the three universities located in Chungcheong province. A total of 217 responses out of the 250 questionnaire were analyzed without the 33 incomplete questionnaires. The results of this study are as follows. First, it was shown that professors' social support had a significant positive effect on the career decision-making self-efficacy and the career preparation behaviors. Second, it shows that the career decision-making self-efficacy played a partial mediating role when the social support of the professors is related to the career preparation behavior. Therefore, the career education based on emotional, informational, material, and appraisal supports of the professors probably play a critical role in improving the career decision-making self-efficacy and the career preparation behaviors of the students majoring in food service & culinary art.

Environmental concern has been an important issue for a few decades, and the extent of consumer demand for eco-friendly consumption has been increased. This study seeks to investigate consumers' willingness to pay (WTP) a premium for eco-friendly cosmetics. This study evaluates how much more a consumer is willing to pay for eco-friendly cosmetics and examines significant factors influencing consumers' WTP for eco-friendly cosmetics. Consumers' WTP is measured using four different ecofriendly cosmetics: low-priced skin care cosmetics, low-priced makeup cosmetics, high-priced skin care cosmetics, and high-priced makeup cosmetics. This study uses the contingent valuation method (CVM) to estimate consumer's WTP for eco-friendly cosmetics. Survey questions were designed using both dichotomous choice and payment card method of CVM. Through face to face interviews and on-line surveys, the data were collected from women between 20 and 49 years old residing in Seoul and Kyeonggi area, Korea, in May 2010. A total of 226 questionnaires (132 from interviews and 94 from on-line) were included for the analytical sample in this study. The data were analyzed using descriptive analysis, T-test and Log-Logit analysis. The findings are as follows: First, the WTP measured by dichotomous choice method was estimated using the Log-Logit analysis. The results showed that the estimated WTP for low-priced skin care cosmetics was 19,152 won, which was 27.7% higher than the reference price, 15,000 won. For low-priced makeup cosmetics, the estimated WTP was 18,524 won, and its green premium was 21.0%. The estimated WTP for high-priced skin care cosmetics was 59,128 won, which was 18.3% higher than the reference price, 50,000 won. For high-priced makeup cosmetics was 57,666 won, and its green premium was 15.3%. Second, the WTP measure by payment card method was estimated using descriptive analysis. The results showed that the respondents were willing to pay 17,955 won for low-priced skin care cosmetics, which was 19.7% higher than the reference price, 15,000 won and 17,595 won for low-priced makeup cosmetics, which was 17.3% higher than the reference price. For high-priced skin care cosmetics, the average WTP was 56,950 won which was 13.9% higher than the reference price, 50,000 won. For high-priced makeup cosmetics, the average WTP was 55,650 won, which was 11.3% higher than the reference price. Overall, the WTP was higher in order of low-priced skin care, low-priced makeup, high-priced skin care, and high-priced makeup. It means that consumers decide degree of premium based on the price and the attributes of eco-friendly products. Third, the findings showed that age, monthly income, and having children or not were statistically significant factors that influenced consumers' willingness to pay for eco-friendly cosmetics. Other explanatory variables such as education, marital status, job, purchase experience of eco-friendly products, and environmental concerns did not show any statistical significance. The major contribution of this study is the investigation of the value of green attributes of the products by using CVM. Unlike most previous researches, this research used two methods of CVM, the dichotomous choice and the payment card, so it enhanced the reliability of research. According to this study, consumers showed price sensitivity when they pay green premium. These findings can be used as useful information to establish marketing strategies for green cosmetics.

The main objective of this paper is to investigate the burnout state, coping types, and their relationship with organizational citizenship behavior, and based on the investigation, to provide some reference materials for effective management of burnout and appropriate methods of coping. For this purpose, employees of Korean Red Cross Blood Center were selected as the subject of the research. Data for empirical analysis were obtained through mail survey using structured and self-administered questionnaire for 282 employees of five Red Cross Blood Centers across the nation. Following is the summary of the results: 1) Degree of organizational citizenship behavior was higher among the married, the forties in age, and the employees whose major reason for choosing to work at the Center was 'to help other people.' On the other hand, degree of burnout was higher among the single but lower among the forties in age and the employees who chose to work at the Center because of suitable abilities and interests. As for the types of coping, problem-oriented coping method was more frequently used by the married, older, relatively more-educated and higher-grade employees. 2) Among the three kinds of burnout, 'achievement burnout' was found to have the greatest influence on the organizational citizenship behavior, negatively affecting organizational citizenship behavior as a whole and all of its components except for 'sportsmanship.' Next was 'impersonality burnout,' which also had negative effect on organizational citizenship behavior as a whole, and altruism, conscientiousness and sportsmanship among the components. Finally, 'emotion burnout' appeared to have positive effect on altruism and courtesy but negative effect on sportsmanship. 3) Among the various types of coping, 'problem-oriented' and 'positive perspective' coping methods were found to positively influence overall organizational citizenship behavior, whereas 'stress dissolution' had negative effect. These results imply that special management, counselling and education are needed for sociodemographic groups with high burnout to utilize problem-oriented and positive perspective coping methods which are considered to have desirable effects in coping with burnout problems. In addition, some methods should be devised to prevent and manage the 'achievement burnout' that was found to have great negative influence on organizational citizenship behavior.

Yukwa samples, made with additions of 0, 10, 20, and 30% Rubus coreanus Miquel extract, were puffed by different puffing methods(convection oven, microwave oven, and fryer) and were then examined for quality characteristics such as moisture content, expansion rate, color, hardness, and sensory qualities, in order to determine the optimal ratio of Rubus coreanus Miquel extract in the formulation and the optimal expansion of Yukwa. The moisture contents of Yukwa base increased as the level of Rubus coreanus Miquel extract increased. And the Yukwa puffed by convection had higher moisture than the samples puffed by microwave oven or frying, with the exception of the sample containing 20% Rubus coreanus Miquel extract. When comparing the expansion rates of samples, no significant differences were found between the control and extract-containing samples puffed by convection, microwave, and frying methods, respectively. However, the sample puffed by frying had the highest expansion rate, whereas the convection-, microwave-puffed samples showed no significant differences. In the convection-, microwave-, and fryer-puffed samples, lightness and yellowness decreased, but redness increased, as the level of Rubus coreanus Miquel extract increased. And the sample puffed by microwave oven had greater lightness as compared to the samples puffed by convection and frying. In terms of hardness, no significant differences were found the control and extract-containing samples puffed by convection and microwave methods. However, hardness was maximal in the sample puffed by convection and lowest in the sample puffed by frying, in which it increased according to the addition of Rubus coreanus Miquel extract. In the consumer acceptance evaluations and characteristics intensity rating tests, the samples puffed using convection and microwave methods showed higher scores for the majority of evaluated characteristics as compared to the samples puffed by frying. And the samples containing Rubus coreanus Miquel extract obtained fairly good scores. In conclusion, the results indicate that additions of 10$\sim$20% Rubus coreanus Miquel extract are optimal for Yukwa that is puffed by convection and microwave methods, as this range provides good physiological properties and reasonably high overall consumer acceptability.

Products of the eruption of Mt. Baekdusan are identified as volcanic materials at the estuaries of the Songhuagang river to north, the Dumangang river to east and the Amnokgang river to west. More speficially, pyroclastic flows, lahars and volcanic floods can affect an area of 400km in radius, centering around Lake Cheonji caldera. However, unlike the millenium eruption, the flow situation has been changed. Because multi-purpose dams and reserviors with a combined pondage of mora than 2 billion tons of water have been built in the rivers of which sources are originated from Lake Cheonji caldera. In addition, the flow of fluids expected to take place when the volcano has erupted is thought to be affected by artificial constructions in both direct and indirect ways. This study calculates the direction of fluids flow by using numerical analyses of pyroclastic flows, lahars and volcanic floods that can occur when the volcano of Mt. Baekdusan has erupted. We also estimate the scope of damages by pyroclastic flows, lahars, volcanic flooding caused by the pondage of the dams and water storages in and around Mt. Baekdusan. Pyroclastic flows transported over the steep slopes at the early times of eruptions move over the mountain slopes, affecting airplanes, and lahars due to leaks of Lake Cheonji could reach as far as major rivers and streams near Mt. Baekdusan. Unlike historical accounts, volcanic flood is expected to be limited in its scope of influence to reservoirs bigger than Lake Cheonji in pondage.

Objectives: Continuous positive airway pressure (CPAP) is effective in the treatment of obstructive sleep apnea syndrome (OSAS), but the major limitation of CPAP may be poor compliance. The aims of the study were to investigate the compliance and side effects of CPAP, and to evaluate the efficacy of CPAP in patients with OSAS. Methods: This study enrolled 106 patients with OSAS who took the CPAP treatment. The severity of daytime sleepiness was measured using Epworth Sleepiness Scale (ESS), and sleep quality and depressive symptoms were assessed by Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Inventory (BDI), respectively. Results: During 29 months of the study period, 41.5% of patients were using CPAP and 38.7% of patients stopped using it. Compared to non-compliant patients, compliant patients had a higher PSQI score and obstructive apnea index. Among non-compliant patients, 51.2% of them stopped using CPAP within 1months. 85.7% of non-compliant patients were discomforted by the CPAP, but much more nasopharyngeal symptoms were reported in the compliant group. ESS (p<0.01), PSQI (p<0.01) and BMI (p<0.01) were reduced significantly after CPAP treatment but not BDI (p=0.86). Conclusions: We concluded that CPAP can reduce the daytime sleepiness, nocturnal sleep disturbance, and body mass index. To increase the compliance of CPAP, we suggest that some education and support are needed at the early stage of the CPAP treatment.

After the revision of the Urban Park Act in 2005, historical parks emerged in Korea to promote the preservation of historical heritage while also offering recreation and education to ordinary citizens. It is now time to examine the characteristics of domestic historical parks by examining their current operational conditions, and seek appropriate institutional improvements. By studying the characteristics of historical parks in various countries, as well as the trends in the designation and development of domestic historical parks, this study attempts to examine the function and role of historical parks, and seeks a direction for future action. Through its literature review, this study also examines the current state of historical parks through cooperation with relevant public officials and experts. The results of the study show that, despite historical resources being concentrated in sites dating to the Joseon Dynasty, they also include heritage pertaining to persons, events, and places. There is also a trend toward increasing the focus on modern heritage. Historical parks show differences across existing cities and new towns, as well as between major cities and provincial cities. Provincial cities showed a recent trend of using historical parks as important resources for strengthening their economics and solidifying their identities. Also, there are many cases where the designated category for a park is changed to a historical park. In such cases, there may be a problem where certain functions of the park run into conflict. Domestic historical parks can be divided into four categories: heritage parks, memorial parks, historical theme parks, and historic parks. Such detailed classification schemes may serve as the strategic foundation for later conservation and usage of historical heritage, as well as a standard for suggesting concrete direction in the operation of historical parks.

Inadequate food handling and poor hand hygiene playa major role in the occurrence of foodborne diseases. The objective of this study was to find out if the level of microbial contamination on the hands of food preparers varies by time during their working period. This study focused on the contamination of aerobic plate count, total and fecal coliforms, Escherichia coli, Staphylococcus aureus, and Salmonella spp. Sampling from left hand and right hand of twenty food preparers was done with glove-juice method at every two hours during their work. Microbiological testing was conducted according to the Food Code of Korea. The microbiological load on the hands was changed over time. Samples taken from their hands before work and at 8 hours showed higher levels of bacteria than those taken at 2, 4, and 6 hours during work and/or after work (p < 0.05). The contamination levels of microorganisms were consistently higher in right hand than in left hand. Poor hand hygiene practices were indicated by the positive results for total and fecal coli forms, E. coli, S. aureus, and Salmonella spp. on the hands of some food preparers. This study indicates food preparers' hands can be a vehicle of pathogen during their work. The results of this study emphasize the importance of hand hygiene education and training targeting the food preparers.

Gabensis village is one of the biggest village In the Wampar Local Level Government area within the Huon Gulf District of Morobe Province with a population of around 3,000. The major staple food is banana which is well complemented by minor staples yam, cassava, Singapore/Chinese taro and sweet potato. Apart from gardening for own consumption, the villagers engage in selling of vegetables, garden staples, cocoa beans, coconuts, timber, chicken, fish and pig meat to supplement their livelihood. Livestock like pigs and chickens are also kept for meat and for commercial purpose. Bettlenut which was once one of the main cash crops has now been overtaken by cocoa due to a disease that had attacked almost the entire bettlenut tree population in the area. Even though the Wau-Bulolo highway cuts through the village and all have access to transport infrastructure, the majority of the population still encounter problems in communication due to poor telecommunication coverage. On average most people earn not more than K50 per week due to constrains in production and marketing among others. Gabensis village has the potential to develop a tourism industry given its natural attraction of Lake Wanam. Beside there is also the natural eel farming and the fish pond at the nearby Potsie village. These natural attractions pose huge tourism potential for the community. As part of government services delivery and development, education and health issues is very much important in the community however there is lack of infrastructural development and poor service delivery especially in the area of health. However, the responsibility is on the community to organize themselves to realize that potential. A well developed agro-ecotourism investments would have positive spillover effects to the community thus contributing towards improving the livelihoods of the many farming families.
