This study was performed to investigate the effect of rosiglitazone, a new antidiabetic agent, on in vivo synthesis of bone collagen. The mice were divided into low-fat diet group (LF), high-fat diet group (HF), and high-fat diet with rosiglitazone (6.3 $\mu\textrm{g}$/kcal diet) group (HF-Rosi), The synthesis of bone collagen was measured by stable isotope-mass spectrometric technique using $^2$$H_2O$ as a tracer. The $^2$$H_2O$ labeling protocol consisted of an initial intraperitoneal injection of 99.9% $^2$$H_2O$, to achieve approximately 2.5% body water enrichment followed by administration of 4％ $^2$$H_2O$ in drinking water for 3 weeks. Although body weight gain and daily diet intake were not significantly different between groups, HF-Rosi had slightly higher body weight gain and daily diet intake than LF and HF. In addition, HF-Rosi showed significantly higher body fat content than LF and HF. Bone collagen synthesis was reduced in HF than LF and further decreased by the treatment of rosiglitazone. These results suggest rosiglitazone affect body fat content and bone turnover in mice.

With the rapid growth of Chinese economy, environmental issues also became a serious problem that public and private sector have to take under consideration. For the sustainable growth of Chinese economy scholars and policy makers agree to the stronger regulation for protection of natural environment, but at the same time worry about its negative effect on economic growth. This paper primarily focus on the relationship between the factors that have the effect on green product purchasing intention and purchasing behavior. Purchasing intention was considered as mediating variable in our model and state-action orientation - as moderating variable. We set 8 hypotheses and tested with structural equation modeling. The result shows that governmental regulation and subsidy, social environment related with green product purchase, and consumer perception on the benefit of green product have positive relationship with purchasing intention, but environmental concern does not show relationship with it. We also proved that state-action orientation has moderating effect between purchasing intention and purchasing behavior. Purchasing intention with action orientation show positive and statistically significant effect on purchasing behavior. This result supports the hypothesis that the attitude of customers has the effect on ones purchasing behavior.

Financial firms strengthen to protect personal information from the leakage, introducing various security solutions such as print output security, internet network Isolation system, isolationg strorage of customer information, encrypting personal information, personal information detecting system, data loss prevention, personal information monitoring system, and so on. Financial companies are also entering the era of cutthroat competition due to accept of the new channels and the paradigm shift of financial instruments. Accordingly, The needs for security for customer information held by financial firms are keep growing. The large security accidents from the three card companies on January 2014 were happened, the case in which one of the outsourcing personnel seized customer personal information from the system of the thress card companies and sold them illegally to a loan publisher and lender. Three years after the large security accidents had been passed, nevertheless the security threat of the IT outsourcing workforce still exists. The governments including the regulatory agency realted to the financail firms are conducting a review efforts to prevent the leakage of personal information as well as strengthening the extent of the sanction. Through the analysis on the application of security policy for outsourcing personnel in case of large-scale Financial IT projects and the case study of appropriate security policies for security compliance, the theis is proposing a solution for both successfully completing large-scale financial IT Project and so far as possible minizing the risk from the security accidents by the outsouring personnel.

This study attempts to evaluate the Korean terrestrial television networks‘ internet site effectiveness, specifically in addressing user motivations and user evaluations and in gauging the broadcasters' feedback. The result shows that the primary motive for using a broadcaster's internet homepage was to obtain information. Overall, the users tended to be dissatisfied with the services, especially with regards to its navigational structure and design and with the insufficient number of appropriate content items. The reason cited highest for dissatisfaction was the fee-based services. Among the three networks, Seoul Broadcasting System, the sole commercial network, received the most complaints from the respondents in this respect. The study results reveal that broadcasters' feedback systems to users were deemed responsive and timely, but a true interactivity between the broadcasters and the viewers was lacking. In conclusion, network televisions' internet sites and increased content access through them have provided a platform for increased communication with their viewers, however, these sites are not yet being fully utilized as effective interactive communication feedback channels but more as a unidirectional information source. In addition, the network television services seem to be lacking in providing users with efficient navigational structure, good design, or adequate content level and quality. Thus, to better serve the public, it is recommended that they improve internet homepage usability by assessing and applying qualitative researches regarding the users.

Global warming caused by excessive greenhouse gas emission is causing climate change all over the world. In Korea, greenhouse gas emission from residential buildings accounts for about 10% of gross domestic emission. Also, the number of deteriorated multi-family housing complexes is increasing. Therefore, the goal of this research is to establish the bases to manage energy consumption continuously and methodically during MR&R period of multi-family housings. The research process and methodologies are as follows. First, research team collected the data on project characteristics and energy consumption of multi-family housing complexes in Seoul. Second, an ontology-based breakdown structure was established with some primary characteristics affecting the energy consumption, which were selected by statistical analysis. Finally, a predictive model of energy consumption was developed based on the ontology-based breakdown structure, with application of CBR, ANN, MRA and GA. In this research, PASW (Predictive Analytics SoftWare) Statistics 18, Microsoft EXCEL, Protege 4.1 were utilized for data analysis and prediction. In future research, the model will be more continuous and methodical by developing the web-base system. And it has facility manager of government or local government, or multi-family housing complex make a decision with definite references regarding moderate energy consumption.

Diets containing 3000 kcal/kg at the crude protein (CP) level of 40% (Diet 1) and 4000 kcal/kg at the CP level of 50% (Diet 2) were fed to the juvenile rockfish, Sebastes schlegeli (35.6 g) at 3-4% body weight for a period of 28 days. Diet 2 promoted significantly higher growth and feed efficiency than Diet 1. Oxygen uptake increased with increasing body weight. The oxygen uptake-body weight relationship of diets 1 and 2 were best expressed by y=0.3218 $e^{0.0592x}$ (R=0.8494) and y=0.3612 $e^{0.0532x}$ ($R^2$=0.8805), respectively. Assimilation efficiency (AE), gross growth efficiency ( $K_1$) and net growth efficiency ( $K_2$) of the fish fed on Diet 2 were 73.8, 16.0 and 22.6%, respec- tively. Fish fed on Diet 2 showed significantly higher AE, $K_1$ and $K_2$ than those fed on Diet 1. Hence Diet 2 con- taining 4000 kcal/ kg with crude protein of 50% is recommended for the Korean rockfish.kfish.

More children today are overweight or obese than ever before. childhood obesity results from an imbalance between the amount of energy consumed and the amount of energy expended. Whether child want to lose weight or maintain a healthy weight, it's important to balance between the calories body takes in and uses. Obesity treatment programs for children and adolescents is to slow or halt weight gain so the child will grow into his or her body weight over a period of months to years. Fasting or extreme caloric restriction is not advisable for children. More physical activity is a key element in the prevention and treatment of obesity. Children can't change their exercise and eating habits by themselves. They need the help and support of their families and parents. Children and adolescents who are just beginning to be physically active should start out slowly and gradually build to higher levels in order to prevent the risk of injury or feel defeated from unrealistic goals. It is important that children and adolescents are encouraged to be physically active by doing things that interest them. FUN physical activities that kids choose to do on their own are often best. Kids need about 60 minutes of physical activity a day, but this does not have to happen all at once. Several short 10- or even 5-minute periods of activity throughout the day are just as good. FUN physical activities will help them establish an active lifestyle early on. Obese people need care not for a short period, but throughout their lives.

Modified atmosphere packaging (MAP) of vacuum, 60% $N_2/40%$ $CO_2$, 100% $N_2$ and 100% $CO_2$ were examined to preserve fried fish cakes and extend their shelf life. When product packages in air were stored at 5, 10, and $15^{\circ}C$ with measurement in quality attributes, aerobic bacterial growth was found to be primary quality factor to determine the shelf life of the product. Huang's model was adopted to obtain the parameters for use in shelf life determination for a variety of packaging and storage conditions. Temperature dependence expressed in Arrhenius equation showed activation energies of 139.4 and 41.8 kJ/mol for inverse of lag time and growth rate of the microbial spoilage, respectively. MAP of 100% $CO_2$ could double the product shelf life at $10^{\circ}C$ compared to air package. High $CO_2$ concentration MAP at low temperature was found to be effective to prolong the shelf life.

Four low fat ground beef groups containing 10% fat plus 0, 5, 10 and 20% additional cooked old rice and a control ground beef containing 30% fat were prepared. Various sensory characteristics and instrumental textures were measured in order to determine the acceptability of low fat ground beef and to find out the most appropriate level of addition of cooked old rice as a fat replacer. Ground beef containg 10% fat had higher flavor and firmness scores than any other ground beef groups. Ground beef with 10% fat plus 5% cooked old rice had higher flavor, particle size, firmness and overall acceptability scores but lower juiciness and tenderness scores than ground beef with higher amount of cooked old rice (10 and 20%) and ground beef with 30% fat. Ground beef containing 10% fat plus 10 and 20% cooked old rice had higher juiciness, tenderness, particle size and overall acceptability scores but lower flavor and firmness scores than any other ground beef groups. Ground beef with 30% fat had higher flavor, juiciness, tenderness and firmness scores but lower particle size and overall acceptability scores. Conclusively, ground beef with the fat content reduced to 10% plus 5 or 10% additional cooked old rice as fat replacer still possessed the desirable sensory and instrumental texture properties.
