The focus of our work is to identify and understand the drivers of alliance performance so that businesses can maximize their chances of a successful alliance-an area that has received little attention in empirical modeling. Although both conceptual and applied research on alliances has increased, an empirically tested comprehensive theoretical model that explains alliance performance has yet to be developed. Using five salient perspective, namely market power theory, transaction cost theory, the resource-based view, institutional theory, real option theory, this paper attempts to provide a theoretical rationale linking motives of global alliance networks on firm's capabilities, partner's capabilities, operating structures, and performances of Korean companies. The key contribution of this study is that it paints a picture of what matters in driving alliance performance. Our work shows the complex nature of driving performance and the interplay of firm's capabilities, partner's capabilities, and operating structures for understanding alliance performances. This study has given us a small but significant step forward towards understanding the intricacies of alliance performance. We are now better able to understand the respective roles played by various alliance factors and derive insights that lead to improved alliance performance.

This study was aimed to identify the diffusion of systemic disease-related knowledge among dental hygienists. Two hundreds and eleven dental hygienists were selected for the study. Data was collected between August 31, 2015 and September 20, 2015 by handing out questionnaires. Returned questionnaires were analyzed by descriptive statistics, t-test, and ANOVA. Dental hygienists showed overall mean of 0.64 on the systemic disease related knowledge. Age, education level, career, and educational experience showed significant influence on the systemic disease knowledge (p<0.01). Dental hygienists revealed overall mean of 0.61 (full mark=1) on the usefulness recognition of systemic disease related knowledge. Age (p<0.001), education level (p<0.01), career (p<0.001), and educational experience (p<0.01) showed significant effects on the usefulness recognition of systemic disease knowledge. Degree of how dental hygienists apply the systemic disease-related knowledge to the service was mean 0.86 (full mark=2). Age (p<0.01), education level (p<0.01), career (p<0.01), and educational experience (p<0.001) had significant impacts on how dental hygienists apply the systemic disease related knowledge to the service. The diffusion of systemic disease knowledge among dental hygienists was 2.17, which represented 'persuade'. These results indicated that a study is needed to understand the diffusion of systemic disease knowledge among dental hygienists and to identify obstacles in the process. Moreover, an education program should be developed to offer practical training on the systemic disease-related knowledge. Further studies should evaluate the effectiveness of the program.

We investigated the effect of mulberry leaf extract (MLE) on blood biochemical parameters of white rats induced TCDD toxicity. Data were analyzed by One-way ANOVA and Post-Hoc Test. The numbers of leukocyte and platelet decreased by TCDD were increased dramatically after treated MLE (p<0.01). The concentration of calcium and magnesium decreased by TT were increased by MLE and shown a statistical significance (p<0.01) but the concentration of phosphorus increased by TT was decreased by MLE. In the test of parameters related to renal function, only the concentration of uric acid in the MLE group was decreased than it in TT group and shown a statistical significance (p<0.01). Also the concentration of blood glucose and the activity of amylase and lipase increased by TT were decreased after treated MLE and shown a statistical significance (p<0.01), and MLE had an control effect for elevating blood glucose. In the test of parameters related to liver function, the acticity of AST, ALT and ALP increased by TT was decreased after treated MLE and shown a statistical significance (p<0.01), and MLE had an improving effect for liver function. In the case of total cholesterol (T,cho), triglyceride( TG), LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) related to lipid metabolism, the amount of T,cho, TG, LDL-C increased by TT were decreased after treated MLE and shown a statistical significance (p<0.01), and MLE had an ability of anti-hyperlipidemia. From these results, we concluded that MLE could mollified TCDD toxicity in white rats exposed to TCDD.

This paper aims to identify the relationship between the number of teeth of the elderly and their life happiness index. A face-to-face interview survey was conducted with elderly residents of Dong-gu, Daejeon from June 27 to July 25, 2012. A Tukey post hoc test and correlation analysis were implemented after a t-test and variance analysis. The results of analysis showed that satisfaction with life related to oral health was significant, but happiness in daily life had no significant difference. For the elderly, the quality of life related to oral health and happiness in daily life had no significant difference. Masticatory performance difference depending on usage of dentures also showed significant difference (p<0.001). The difference of masticatory performance depending on the number of teeth was analyzed by a correlation analysis. The present number of teeth, present anterior teeth and molars demonstrated a correlation. Quality in life related to oral health depending on the number of teeth correlated with the present number of teeth, present anterior teeth and present molars.

Necessarily traffic policies have been biased in car than pedestrian, so pedestrian's environment is getting worse. Result of this situation our accident rate is high as 36.4%, compared to OECD member countries with average rate of 17.8%(in 2009). Increasing interest for pedestrians environment improvement, and it make an effort to build environment to guarantee walk and safety of pedestrians. Analysis on the binary logistic regression(BLR) was used. The dependent variable is occurring from the road width of less than 9m accident, and independent variable extracted can be obtained from the traffic accident data. Traffic accident on roads having width of less than 9 meters affecting variables is when the driver is straight, when the driver is female, when the pedestrian is walk driveway, and so on. To prevent it, efforts is demanded to protect handicapped, to build safe pedestrians environment using C-ITS and to decrease speed of going straight vehicle on roads having width of less than 9 meters.

The application of livestock manure to cropland is a practice that has been used for centuries. Agricultural crops can utilize nutrients from manure, and the producer can utilize land for disposal, although in a "sustainable system" the concept is manure utilization and not waste disposal. However, meeting regulatory criteria regarding microbial quality remains an expensive and time consuming process. The purpose of this study was to quantify the level of environmental impact of soil moisture and temperature on fecal coliform (Escherichia coli or E. coli) survival in upland soils for sound application of livestock manure. Samples were collected up to 30 days depending on the given conditions. The inactivation rate of E. coli increased linearly with increased temperature while the inactivation rate gradually decreased with decreased soil moisture level. The overall findings of this study showed that the temperature was the limited factor on E. coli survival in soils over soil moisture content. This study will provide useful and practical guidelines to applicators of soil in deciding appropriate handling and time frames for land application for sustainable agriculture.

This study aims to provide basic data for maintaining and promoting health of obese middle-aged women who are interested in various chronic diseases such as cardiovascular disease and coronary artery disease by comparing and analyzing the effect on body composition and lipid metabolism through a 12-week Pilates mat exercise program for obese middle-aged women. This study targeted middle-aged women residing in Gyeonggi-do A, who are obese middle-aged women in their 40s and 50s with a body fat ratio of 30% or more, and had no regular exercise in the past three months. Obese middle-aged women(n=19) were divided into two groups, the Pilates mat exercise program group(n=9) and the control group(n=10), conducting exercise for 60 minutes three times a week for 12 weeks. As a result of analysis, the exercise group had a positive effect on body weight, skeletal muscle mass, body fat mass, body fat percentage, and BMI in body composition, but not in the control group. In the lipid metabolism, the exercise group had a positive effect on TC, TG, HDL-C, LDL-C, and FFA, but not in the control group. These results suggest that the 12-week Pilates mat exercise program conducted in this study is an exercise program that can prevent cardiovascular and chronic diseases in obese middle-aged women.

This study investigates Korean middle school students' perceptions as global citizens (i.e. ecological worldview, social and moral compassion, and socioscientific accountability) of Socioscientific Issues (SSI). We developed questionnaires that consisted of 20 Likert-type items to gauge their preceptions of the three different SSI contexts (i.e. nuclear power generation, bio-technology, climate change), and administered them to 225 9th grade students in Seoul. The results revealed that participants showed relatively high scores for ecological worldview but scored low on social and moral compassion across the SSI contexts. In addition, participants presented much higher scores for ecological worldview and socioscientific accountability regarding the issues of climate change. The participant responses indicated that they perceived more inter-connectedness with the environment and felt the responsibility of promoting sustainable development more to prevent further devastation in the context of climate change compared to nuclear power generation or biotechnology.
