The influence of different storage temperature and packaging methods on the flying cultured eel bone were investigated. The acid values, peroxide values and fatty acid composition were measured during storage 20$^{\circ}C\;and\;40^{\circ}C$ for 60 days. The lipid oxidation was rapidly progressed with the increased temperature. The addition of oxygen absorber remarkably repressed lipid oxidation during storage of the living cultured eel bone at $20^{\circ}C\;and\;40^{\circ}C$, followed by $N_{2},\;BHA,\;\alpha$-tocopherol and control. The monounsaturated fatty acid content was the highest in the frying cultured eel bone, followed by saturated fatty acid and polyunsaturated fatty acid. The major fatty acids were oleic acid, palmitic acid and linoleic acid. The saturated fatty acids increased with the rise of storage temperature and prolonging the storage period, while monounsaturated fatty acid and polyunsaturated fatty acid were decreased. The changes of fatty acid composition were the lowest in sample by packing with oxygen absorber, followed by packing $N_{2},\;BHA,\;\alpha$-tocopherol and control. from the result of sensory evaluation, sample by packing with oxygen absorber were rated as higher quality than the others.

This study examined effects of 12 weeks of body weight based combined exercise training (resistance training for 30 min, aerobic training for 30min) on body composition (% body fat, lean body mass, fat mass and BMI (body mass index)) and cardiovascular factors (ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV)) in elderly women. A total of 32 subjects participated in this study, and were randomly divided into either exercise group (n = 16, EG) or control group (n = 16, CG). All variables at pre-test were analyzed by independent t-test for baseline test, and all data post the study period were analyzed by two-way repeated measures ANOVA with contrast testing (α = 0.05). Our results indicate that body composition (% body fat, lean body mass, fat mass and BMI) in both EG and CG do not differ significantly. However, the right and left sides of baPWV in EG was significantly reduced, as compared to CG. Taken together, these results indicate that combined exercise training for 12 weeks positively influences the cardiovascular factors, and may prevent cardiovascular diseases in elderly females (over 65 years), thereby resulting in increased quality of life for the elderly.

The Korean language major is being activated in line with the increasing number of international students who are studying in South Korea. Therefore, the motivation for selecting a university major varies according to the background, environment, and values of each student. Thus, it is meaningful to examine the motivation of international students to select their major and their satisfaction on the major. In this study, 173 international students living in Seoul were surveyed and the data were analyzed using SPSS 21.0 and AMOS 23.0 to demonstrate the structural relationship between their motivation for selecting the major and their satisfaction about the major. From analysis result, their motivation for selecting a Korean language major were classified into internal and external motivations, and their major satisfaction was classified into perception satisfaction, relationship satisfaction, subject satisfaction, and general satisfaction. Regarding the motivations to select a Korean language major, the level of external motivation was very high, and among the major satisfaction, the level of general satisfaction was the highest. Furthermore, the external and internal motives had significant positive effects on all the categories of major satisfaction, including the perception satisfaction, relationship satisfaction, subject satisfaction, and general satisfaction. This study suggests effective methods to improve the satisfaction of international students about the Korean language major such as the provision of information about and opportunities for employment using their major and the provision of a high quality.

Objective : This study aimed to investigate the awareness and experience of community-based dysphagia therapy and related education in community-dwelling older adults. Methods : A total of 89 older adults were recruited from a public health center in Gyeonggi-do. Awareness, experience, and related education regarding community-based dysphagia therapy were analyzed using descriptive statistics. Results : We analyzed 89 questionnaires. Awareness, treatment experience, and education regarding dysphagia were low; however, the importance and intention to participate were high. Respondents wanted education about proper chewing and safe swallowing, oral health, oral motor exercise, and participation in community-based dysphagia programs in public health centers. The reason for the lack of experience in dysphagia education and therapy is insufficient information and opportunities. The respondents had a good understanding of dysphagia symptoms. Conclusion : Dysphagia therapy maintains swallowing and eating functions as a life-long Activity of Daily Living, and is a very important area in community rehabilitation. Based on the results of this survey, the necessity and importance of community-based dysphagia were identified. It is time to provide correct information and develop a systematic education program for community-based dysphagia therapy. Occupational therapists need to play an active role in improving quality of life by early detection and providing proper intervention.

With increasing interest in environmental issues and the quality of surface water becoming inadequate for water supply, the Korean government has launched a groundwater development policy to satisfy the demand for clean water. To drive this policy effectively, it is essential to guarantee the accuracy of sustainable groundwater yield and groundwater use amount. In this study, groundwater use was monitored over several years at various locations in Korea (32 cities/counties in 5 provinces) to obtain accurate groundwater use data. Statistical analysis of the results was performed as a method for estimating rational groundwater use. For the case of groundwater use for living purposes, we classified the cities/counties into three regional types (urban, rural, and urban-rural complex) and divided the groundwater facilities into five types (domestic use, apartment housing, small-scale water supply, schools, and businesses) according to use. For the case of agricultural use, we defined three regional types based on rainfall intensity (average rainfall, below-average rainfall, and above-average rainfall) and the facilities into six types (rice farming, dry-field farming, floriculture, livestock-cows, livestock-pigs, and livestock-chickens). Finally, we developed groundwater-use estimation equations for each region and use type, using cluster analysis and regression model analysis of the monitoring data. The results will enhance the reliability of national groundwater statistics.

Although the Dreamland site was the only flat amusement park in the northern part of Seoul, the site lost its function as a regional park due to aging and, therefore, was no longer in use. The site is surrounded by currently existing high dense low-story housing blocks and proposed new towns. A renovation plan for Dreamland was raised by the City of Seoul to enhance the quality of the urban environment in the northern part of Seoul. This study articulates the design concepts and strategies of the prizewinning work of the International Design Competition for Gangbuk Large Park. The three key points can be summarized as follows: First, this design proposal tried to find a new possibility for a large mountain park in an urban areas. These days, mountain parks are used limitedly as ordinary living spaces for activities such as a walking, hiking, and physical training. New strategies were sought to reconstruct the sentiment with which our ancestors enjoyed the mountains. Second, this proposal tried to make Dreamland a socially self-sufficient park. We designed a park which generates self-energy and which communicates with the city, not a park which only exists as a green island in a city. Lastly, rain fed paddy fields, a typical Korean vernacular landscape, was a tangible space which represented people's life-styles harmonizing with the nature. Rain fed paddy fields is a design motif which puts the three surrounding mountains together with the site. It is expected that the new design will works as a noted place.

This paper presents an evaluation index for the supply levels of pedestrian facilities in residential area planning. The pedestrian facility supply levels reveal the quality of a residential area, and can be associated with the resident living standards and satisfaction, pedestrian safety levels, and the effectiveness of the construction cost. This research conducted multifaceted procedures for the index development, and these procedures start first by identifying dominant influencing factors on pedestrian travel demand by reviewing the final reports of site planning in more than eight already-completed residential development sites. Second, based on the Space Syntax model, which was initially developed in the UK by establishing statistical relationships among an integration index, population size (persons/day), and the total development area, this research formulated a set of pedestrian demand estimation models. Then these models were utilized in forming a pedestrian facility supply index by integrating the new models and their results with the available accepted practice in the residential planning sector. This was necessary because planners want to understand the total supply level of pedestrian facilities in a residential area during the initial design stage. Finally, to test the model validity in satisfying pedestrian satisfaction, the research included a resident satisfaction interview, and it was revealed that the evaluation index developed in this research could provide planners and engineers with more promising results. It is therefore anticipated that this research can be of service when designing pedestrian facilities in future residential area planning and design activities.

It turned out that there was a direct or an indirect relationship among global warming, urban heat island effects, urban and traffic environments, and public's health. In particular, unusual climate phenomena such as frequent heavy rainfall and scorching heat in a row that had rarely happened before have a negative effect on quality of life for people living in urban areas. This study focuses on the effects of roadway geometric design and traffic conditions on air temperature of roadside in Seoul Metropolitan Areas, controlling of roadway micro-climate environment. Five roadway segments containing different roadway and traffic conditions in terms of traffic median with trees, street trees, traffic volume and average travel speeds were surveyed. According to statistical results(t-test) from three roadway air temperature regression model estimations, air temperature is found to be different from one another in three periods-morning, afternoon and evening. Regarding roadway geometric design, air temperature of urban roads with vegetated median strips is lower about 1.3~2.2 degrees in celcius. Higher traffic volumes per lane and lower average travel speeds will tend to increase roadside air temperature, and efficient traffic operation policies can protect from increasing roadside air temperature in urban areas.
