Under the international business circumstance, global supply chain management is considered a vital strategic challenge to small and medium-sized enterprises(SMEs) suffering from deficient resources and capabilities to exploit overseas markets comparing with large corporations. That is because they can expand their business domains into overseas markets by establishing strategic alliances with global supply chain partners. Although a wide range of previous researches have emphasized the cooperative networks in the chain, most are ignoring the importance of developing relational characteristics such as trust and reciprocity with the partners. Besides, verifying the relational factors influencing firms' export performances, some studies proposed different and inconsistent factors. According to the social capital theory, which is the social quality and networks facilitating close cooperation of inter-individual and inter-organization, provides the integrated view to identify the relational characteristics in the aspects of network, trust and reciprocal norm. Meanwhile, a number of researchers shows that global entrepreneurship is the internal and intangible resource necessary to promote SMEs' internationalization. Upon closer examination, however, they cannot explain clearly its influencing mechanism in the inter-firm cooperative relationships. This study is to verify the effect of social capital accumulated within global supply chain on SMEs' qualitative and quantitative export performance. In addition, we shed new light on global entrepreneurship expected to be concerned with the formation of social capital and the enhancement of export performances. For this purpose, the questionnaires, developed through literature review, were collected from 192 Korean SMEs affiliated in Korean Medium Industries Association and Global Chief Executive Officer's Club focusing on their memberships' international business. As a result of multi-regression analysis, the social capital - network, trust and reciprocal norm shared with global supply chain partner - as well as global entrepreneurship - innovativeness, proactiveness and risk-taking - have positive effect on SMEs' export performances. Also global entrepreneurship affects positively social capital which has mediating effect partially in the relationship between global entrepreneurship and performances. These results means that there is a structural process - global entrepreneurship(input), social capital(output), and export performances(outcome). In other words, a firm should consistently invest in and develop the social capital with global supply chain partners in order to achieve common goals, establish strategic collaborations and obtain long-term export performances. Furthermore, it is required to foster the global entrepreneurship in an organization so as to build up the social capital. More detailed practical issues and discussion are made in the conclusion.

In order to reinforce the role of primary care physician and o improve doctor-patient relationship, the Korean government tried to introduce 'Family Doctor Registration Program' into Seocho-Gu in Seoul, Ansung-Gun and Paju city in Kyunggi-Do in Oct. 1996. Community residents and doctors in those area did not show much interest in this project because of low incentives. We have done this study to see how much people know 'Family Doctor Registration Program' and what is people's real needs about 'Family Doctor Registration Program'. We selected 1,800 telephone numbers in Seoul, Chongju city, and Ansung-Gun by multi-stage stratified random sampling. Three trained survey personnels called them and got answers to the premade questionnaire until they completed the questionnaires of 200 persons in each community. The calling time was 7-9 p.m. from Monday to Friday, 3-9 p.m. on Saturday, and 9 a.m. to 9 p.m. on Sunday. We dropped out the persons who did not respond 3 times. The subjects consisted of 222 male and 367 female residents. Their ages ranged from 20 to 78: 24.8% in their 30s, 23.4% in their 20s, 22.5% in their 40s in male, and 35.2% in theirs, 22.5% in their 40s, 18.5% in their 20s in female. 9.9% of male and 13.2 % of female had their Family Doctors. The specialties of their Family Doctors were internists in 56.2%, general surgeons in 11.0%. The persons who did not have their family doctors were asked which doctors they would prefer if they had choices of family doctor. The results were internists in 50.3%, family physicians in 13.0%, pediatricians in 4.8%. Only 16.0% residents knew that government tried to introduce Family Doctor Registration Program. The 'Family Doctor Registration Program' was not well known to people. The results of our study showed that more effective incentives and public notifications are needed to activate this program.

Purpose : To compare dynamic susceptibility contrast imaging, diffusion-weighted imaging, and susceptibility-weighted imaging (SWI) for the differentiation of tumor recurrence and delayed radiation therapy (RT)-related changes in patients treated with RT for primary brain tumors. Materials and Methods: We enrolled 24 patients treated with RT for various primary brain tumors, who showed newly appearing enhancing lesions more than one year after completion of RT on follow-up MRI. The enhancing-lesions were confirmed as recurrences (n=14) or RT-changes (n=10). We calculated the mean values of normalized cerebral blood volume (nCBV), apparent diffusion coefficient (ADC), and proportion of dark signal intensity on SWI (proSWI) for the enhancing-lesions. All the values between the two groups were compared using t-test. A multivariable logistic regression model was used to determine the best predictor of differential diagnosis. The cutoff value of the best predictor obtained from receiver-operating characteristic curve analysis was applied to calculate the sensitivity, specificity, and accuracy for the diagnosis. Results: The mean nCBV value was significantly higher in the recurrence group than in the RT-change group (P=.004), and the mean proSWI was significantly lower in the recurrence group (P<.001). However, no significant difference was observed in the mean ADC values between the two groups. A multivariable logistic regression analysis showed that proSWI was the only independent variable for the differentiation; the sensitivity, specificity, and accuracy were 78.6% (11 of 14), 100% (10 of 10), and 87.5% (21 of 24), respectively. Conclusion: The proSWI was the most promising parameter for the differentiation of newly developed enhancing-lesions more than one year after RT completion in brain tumor patients.

This study examines the negative relationship between accounting conservatism and excess executive compensation and examines whether their relationship increases as managerial incentive compensation intensity increases. For this purpose, a total of 2,755 company-years were selected for the analysis of the companies listed on the Korea Stock Exchange from December 2012 to 2016 as the final sample. The results of this study are as follows. First, there is a statistically significant negative relationship between accounting conservatism and manager overpayment. This implies that managers' incentives to distort future cash flow estimates by over booking assets or accounting profits in order to maximize their compensation when manager compensation is linked to firm performance. In this sense, accounting conservatism can reduce opportunistic behavior by restricting managerial accounting choices, which can be interpreted as a reduction in overpayment to managers. Second, we found that the relationship between accounting conservatism and excess executive compensation increases with the incentive compensation for accounting performance. The higher the managerial incentive compensation intensity of accounting performance is, the more likely it is that the manager has the incentive to make earnings adjustments. Therefore, the high level of incentive compensation for accounting performance means that the ex post settling up problem due to over-compensation can become serious. In this case, the higher the managerial incentive compensation intensity for accounting performance, the greater the role and utility of conservatism in manager compensation contracts. This study is based on the fact that it presents empirical evidence on the usefulness of accounting conservatism in managerial compensation contracts theoretically presented by Watts (2003) and the additional basis that conservatism can be used as a useful tool for investment decision.

We investigated environmental problems related to clothing, and attempted their practical solutions using Future Problem Solving Program in order to cultivate the creative character in teenagers. We applied "teaching and learning plans" to seventy-seven the first graders of high school students in 2 classes in Gyeonggi-do, one hour per day for 3 weeks, from August 23 to September 8 2011. Statistical analyses were performed using the SPSS for Windows software(version 17.0). Mean differences in results between pretest and posttest were evaluated using Student's t-test. We selected 'production of fabrics, production of clothing, disposal and recycling of clothing and washing of clothing' as the learning theme in educational content factors of 'clothing culture in consideration of environment'. And we developed thirteenth teaching and learning plans and educational materials including 4 problems, 2 worksheets, 10 team worksheets, 7 video materials and 7 Power Point materials using Future Problem Solving Program(FPSP). The measurements of fluency, flexibility, originality and problem-solving ability are significantly improved. The level of creativity in the items of fluency, flexibility and originality, in particular, exhibited marked improvement, 'below-average' to 'above-average', regardless of academic records and gender. Problem-solving ability in female students was more effective than that of male, but it showed no significant correlation with academic records. The analysis of character-change showed the highest improvement in the awareness on the protection of environment, the character factor in the educational contents. Personalities, confidence, consideration and cooperation in learning method of FPSP also exhibited a significant improvement. But character-change did not correlate with academic records or gender. In the present study, we found that home economics has a positive effect on cultivating creative character. When we selectively and properly apply a course of creative problem-solving of FPSP and a course of creative output to students, we can increase their ability to solve problems, cultivate their creative character and further enhance their interest on home economics.

Purpose: This study has been conducted in order to examine the oral health status and dental prostheses status, and the effects of dental prostheses to the oral health related quality of life among the elderly using social welfare centers. Material and methods: For this purpose, the researcher conducted a questionnaire survey and oral examination of 275 samples of old persons using 7 social welfare centers located in Daejeon metropolitan city. The oral health related quality of life was measured by GOHAI (Geriatric Oral Health Assessment Index). Results: 1. The less age and the more education and the more subjective economic status and living with spouse of family status, the higher GOHAI showed. 2. Mean age of first using of removable denture is 62.11 years old and average life cycle of removable denture is 10.76years. 57.5% of study subjects use removable denture and complete denture user of study subjects are 13.8%. 3. In the case that they use fixed prostheses rather than removable ones and in the complete denture they use both sides (upper and lower) rather than single side, showed higher GOHAI. 4. In the case that they showed higher degrees of satisfaction with dental prostheses and can use them always and showed no necessity for new dental prostheses and denture adaptation is good, GOHAI showed higher. Conclusion: In order to improve oral health related quality of life among the elderly who have many missing teeth, it is required to restore their masticatory ability to the normal level by restoring the missing teeth which has lost its function through providing proper dental prostheses.

This purpose of this study is to academically define what "luxury products" mean, and to clarify the cognitive structural relationship between product attributes and "luxuriousness" in relation to the determinant of luxuriousness that eventually affects the purchase intention of consumers. This study is also written under the theory that luxuriousness leads to benefits such as functional benefit, experiential benefit, symbolic benefit, and exclusive benefit; which all provide core values to consumers and serve as effect factors that influence the psychological satisfaction of consumers. The commonly discussed measure of the determinant of luxuriousness has often failed to adequately describe the reasons to why the consumers prefer luxury products. This study also aims to suggest a new path in how and what the consumers perceive as luxury products, and to conceptualize what luxuriousness means in the marketing perspectives on the background of a previous theory. The part of product attributes are divided in the following sections: the quality and design of functional cues and brands of symbolic cues, as well as prices. The part of the determinant of luxuriousness is divided in sections of superiority, scarcity, differentiation, and traditionality. Therefore, this study used the theoretical concept used in such common measures as well as 282 examples to empirically analyze the relationship between product attributes and luxuriousness of luxury products, and how such affect the purchase intentions of consumers. The survey used to aid this study targeted luxury product consumers regarding "B" brand of automobiles. Using the analysis through a structural equation model, the study draws a conclusion that in a relationship between product attributes and luxuriousness, quality(which is one of the functional cues) affects the facts of superiority, differentiation in a significant way, and design affects the factors of scarcity in a significant way. And brand(one of the symbolic cues) significantly affects the factors of traditionality within the luxuriousness factors, and price appeared to affect superiority and scarcity. Additionally, the brand of product attributes significantly affects purchase intention, and superiority and scarcity of luxuriousness affects purchase intention in a significant way. The structural concept of luxury and luxuriousness suggested in the study will provide the theoretical basis for building a new case study, and the determinants of luxuriousness in the marketing perspective will be a practical help for checking the consumers' psychological reasons for purchase.

Purpose : To evaluate clinical outcomes after anterior cruciate ligament (ACL) reconstruction in middle-aged patients and determine the factors affecting the outcome. Subjects and Methods : Clinical results obtained from 60 cases (60 patients) older than 40 years of age at the time of surgery and 58 cases (58 patients) younger than 40 years of age who underwent ACL reconstruction between August 1988 to January 2002, return to sports activity, and stress radiographs using Telos instrument were compared. Results : The Lysholm knee score was improved from the preoperative score of 54.0 points to the postoperative score of 92.9 in patients older than 40 years of age and was improved from 56.2 points to 92.2 points in patients younger than 40 years of age. Clinical outcome was excellent in 51 cases $(85\%)$ and good in 9 cases $(15\%)$ in patients olde. than 40 years of age and was excellent in 47 cases $(81.0\%)$ and good in 11 cases $(19.0\%)$ in patients younger than 40 years of age. There was a significant difference in the rate of returning to preoperative sports activity between patients older than 40 years of age ($60\%$, 36 cases) and younger than 40 years ($82.8\%$, 48 cases). According to Telos stress radiography, the preoperative difference of 11.2 mm was decreased to the postoperative difference of 3.1 mm in patients older than 40 years of age and the preoperative difference of 10.7 mm was decreased to the postoperative difference of 2.9 mm in patients younger than 40 years of age. Clinical outcome did not show significant correlation with age, gender, surgery method, the presence of additional injury, and the rate of return to sports activity before receiving injury (p>0.05). Conclusion : Age didn't have a significant influence on the final outcome of ACL reconstruction and good results could be obtained with ACL reconstruction even in middle-aged patients.
