The disaster from functional gastrointestinal disorders (FGID) has detrimental impact on the quality of life of the affected population. There are, however, rare diagnostic methods for FGID. Our research group identified recently that the gastrointestinal tract well of the patients with FGID became more rigid than that of healthy people when palpating the abdominal regions overlaying the gastrointestinal tract. The objective of the current study is, therefore, to identify feasibility of a diagnostic system for FGID based on ultrasound technique, which can quantify the characteristics above. Two-dimensional finite difference (FD) models (one normal and two rigid models) were developed to analyze the reflective characteristic (displacement) on each soft-tissue layer responded after application of ultrasound signals. Based on the results from FD analysis, the ultrasound system for diagnosis of the FGID was developed and clinically tested via application of it to 40 human subjects with/without FGID who were assigned to Normal and Patient Groups. The results from FD analysis showed that the maximum displacement amplitude in the rigid models (0.12 and 0.16) at the interface between the fat and muscle layers was explicitly less than that in the normal model (0.29). The results from actual specimens showed that the maximum amplitude of the ultrasound reflective signal in the rigid models $(0.2{\pm}0.1Vp-p)$ at the interface between the fat and muscle layers was explicitly higher than that in the normal model $(0.1{\pm}0.0Vp-p)$. Clinical tests using our customized ultrasound system showed that the maximum amplitudes of the ultrasound reflective signals near to the gastrointestinal tract well for the patient group $(2.6{\pm}0.3Vp-p)$ were generally higher than those in normal group $(0.1{\pm}0.2Vp-p)$. These findings suggest that our customized ultrasound system using the ultrasound reflective signal may be helpful to the diagnosis of the FGID.

As public attention on Well-being culture increases, it is now considered to be a new trend of modern society. The purpose of this study is to publicize the necessity of design products which are advanced in quality and encourage the use of it. The researcher judged that study on design of lighting product to adopt well-being trend is in preliminary level and aims to research on the tendency of well-bing trend and lighting design which the consumer of this age is demanding. As the result of changes in modern consumption trend, design is considered to be a factor of capricious cultural phenomenon. In addition to this, as high technology such as ubiquitous develops with the degitalisation and informatization, the consumer are paying attention to dynamic products rather than static products or products which respond to external stimulus. Products which adopt well-being trend pursuing nature friendly life are particularly preferred It means that not only the basic function of products but also design which satisfy the five sense is required. Modern consumers use products in various way. However, the pro-environmental and human-centered tendency is tried only in very limited area and general study on this matter is extremely rare. This study analyzes the factors which intercepts the adoption of well-being trend to lighting products and seeks for an alternative to solve the problem. Interaction design with well-being trend was adopted to lighting design and the result presented that there is a possibility to differentiate existing lighting design by adding interaction design to the existing lighting design. Therefore, the need for further study on this matter is presented.

The purpose of this study is that I should look for a desirous directions about home economics by studying the requirements and perception of the high school parents who have finished the course of home economics. It was about 600 parents whom I have searched Seoul-Pusan, Ganwon. Ghynggi province, Choongcheong-Gyungsang province, Cheonla and Jeju province of 600, I chose only 560 as apparently suitable research. The questions include 61 requirements about home economics and one which we never fail to keep among the contents, whenever possible and one about the perception of home economics aims 11 about the perception of home economics courses and management. The collections were analyzed frequency, percent, mean. standard deviation t-test by using SAS program. The followings is the summary result of studying of it. 1. All the boys and girls learning together about the Idea of healthy lives and desirous human formulation and knowledge together are higher. 2. Among the teaching purposes of home economics, the item of the scientific principle and knowledge for improvements of home life shows 15.7% below average value. 3. The recognition degree about the quality of home economics is highly related with the real life, and about the system. we recognize lacking in periods and contents of home economics field and about guiding content, accomplishment and application qualities are higher regardless of sex. 4. The important term which we should emphasize in the subject of home economics is family part. 5. Among the needs of home economic requirement in freshman, in the middle unit, their growth and development are higher than anything else, representing 4.11, and by contrast the basic principle and actuality is 3.70, which is lowest among them. 6. In the case of second grade requirement of home economics content for parents in the middle unit young man and consuming life is 4.09 highest. 7.

It is important to prescribe and take medicines that are appropriate for symptoms, since medicines are closely related to human health and life. Moreover, it becomes more important to accurately classify genuine medicines with counterfeit, since the number of counterfeit increases worldwide. However, the number of high-quality experts who have enough experience to properly classify them is limited and there exists a need for the automatic technique to classify medicine tablets. In this paper, we propose a method to classify the tablets by using a handheld spectrometer which provides both Near Infra-Red (NIR) and visible light spectrums. We adopted Support Vector Machine(SVM) as a machine learning algorithm for tablet classification. As a result of the simulation, we could obtain the classification accuracy of 99.9 % on average by using both NIR and visible light spectrums. Also, we proposed a two-step SVM approach to discriminate the counterfeit tablets from the genuine ones. This method could improve both the accuracy and the processing time.

The purpose of this study was to provide better understanding of longitudinal effects of early maternal employment on mother-child relationship using 1364 families participating the NICHD Study of Early Child Care in the U.S. Based on the information on maternal employment from 6 months after the child's birth, three employment groups were created: mothers who had always worked more than 30 hours per week, mother who had worked part-time or had been inconsistently employed, and mothers who had never worked. At 36 months, mothers who had extensively employed for the first 36 months showed significantly lower level of supportive presence compared to mothers who had never worked. Mothers who had partly employed for the first year of child's life displayed higher level of supportive presence at 36 months compared to mothers in the other two 12 month employment groups. No other significant employment group differences were found in the mothers' respect for child's autonomy and hostility at 36 months. At first grade, mothers in three employment groups were not different in their relationship with their child. The findings suggested that maternal employment, specifically early extensive maternal employment, does not consistently predict lower quality of mother-child interaction in two or three years later.

As Social Welfare Service Act was revised in 2011 and its enforcement decree was revised in 2012, the function of local social welfare center was classified into 3 functions such as case control function, service supply function and local society systematization function. Therefore, from 2013, local social welfare center faces the assignment to establish its status as a core subjectivity of local social welfare while maintaining function, role, business, program, service and organization system required for local social welfare center. Currently, there are internal and external limit factors for local social welfare center to perform its original function. The external limit factors are competition with similar organization, diversification of welfare desire depending on social change, insufficient service network construction and lack of partnership between private sector and government. The internal limit factors are lack of local social organization's ability, program issue, insufficient resource, insufficient manpower, etc. In order for local social welfare center to overcome the limit factor and establish the core status for improving the life quality of resident, it should concentrate its ability on local society systematization, construct human & material support network related to local social welfare, minimize social education program and simple relief project gradually, suggest the reasonable direction for village to nurture resident organization, develop the program based on the research on local resident's desire and create the partnership between private sector and government.

This study assessed the thermal comfort of new towns in the Seoul Metropolitan Area (Ilsan, Bundang, Dongtan1) using PET (Physiologically Equivalent Temperature) which refers to real human heat stress. The relationship between PET and urban spatial elements was also analyzed using multiple regression analysis. The study results show that the thermal comfort of Dongtan 1, which is considering a reduction of the urban heat island effect in the planning phase, is higher than other cities. In addition, through regression results, the impervious ratio, floor area ratio, commercial area ratio, and residential area ratio were found to be major factors increasing PET. Moreover, the river area ratio and NDVI were found to be major factors decreasing PET. This study has scientific significance as research that focuses on the assessment of thermal comfort scientifically and definitely, by estimating PET for an entire urban area using GIS analysis that included remote sense analysis and the wind field model. The results of this study can be used in preparing more effective urban plans for the promotion of citizen thermal comfort.

The protein contents of soy protein isolate (SPI) and soft wheat flours were 83.5% and 8.5%, respectively. The addition of SPI increased the protein content but decreased the sedimentation value. Alkaline water retention capacity (AWRC) value increased with SPI addition and was highly correlated with protein content. Increasing SPI flour content significantly decreased the maximum, minimum and final viscosities. Mixograph peak time was positively correlated with protein content and AWRC. The PH and specific gravity of the cake batter increased with increasing SPI content. The SPI addition reduced the loaf and specific loaf volume compared with soft wheat flour. The lightness of the cake crust decreased, while the redness and yellowness increased, with SPI flour addition. SPI addition resulted in a decrease of overall acceptability, but an increase in hardness.

The Cooperatives Act was enacted. This enabled people to establish easily cooperatives at various fields. A cooperative is an important vehicle for rural community development. Therefore, the enactment of the Cooperatives Act can be a significant chance for rural policy. The Cooperatives Act have made three significant changes. First, cooperatives can start businesses at all the fields except for financial and insurance business. Second, requisites for people to establish cooperatives have been alleviated exceptionaly. Third, the Cooperatives Act introduced a new cooperative organization, social cooperative which aims to serve the socially excluded class. The self-help approach places rural community members at the core of a development process with two goals: to improve the quality of life within the community and to facilitate the community's capacity building. Community cooperatives contribute to accomplish those goals. One of the roles for cooperatives is to provide products and services at competitive prices. Providing a good or service at a competitive price bcomes increasingly important in some rural communities declines. Cooperative development processes have bic impacts on the ablility of community members to increase human asset and social capital. We conducted a survey targeting rural community businesses to grasp inclinations toward establishing cooperatives. The Cooperatives Act has gained low level of recognition. But so many community businesses wanted to establish cooperatives. This means there is a possibility for many community businesses to establish cooperatives without sufficient understanding. We suggested some policy issues for coping with this situation, as followings. First, the governments should provides rural community residents with opportunities to learn about cooperatives. Second, the current legal systems and regulations about business and social service should be reviewed to do away with the possible discrimination between the new cooperatives and the other forms of incoporation. Third, the cooperation of cooperatives should be encouraged and facilitated in rural communities.
