Recently, there happens many purchasing cases encouraged by friends' recommendation in SNS (Social Network Service). This study investigates the effect of friend recommendation on consumers' purchasing heuristic. For this purpose, we compare the effect of friend recommendation with consumer recommendation in terms of trustworthy, specialty, relevancy. Usually, the frequency of friend recommendation is far lower than that of consumer recommendation. Hence, we examine how the effect of information source (friend recommendation or consumer recommendation) is moderated by the frequency of recommendation, as well. As results, this study finds out that, under the same frequency, friend recommendation does not have significantly stronger effect on the purchasing heuristic, although friend recommendation is evidenced as one of significant heuristic inducers. However, in terms of trustworthy, friend recommendation is significantly superior to the consumer recommendation. Moreover, under sufficiently higher frequency, friend recommendation works as better heuristic factor than consumer recommendation. The results deliver managerial implications in the perspective of understanding consumers' purchasing decisions and responding strategies of firms.

This study analyzed the degree of demand for genetically modified organisms(GMOs) to provide the basic information for consumers' reasonable purchase decision making and their right to know about GMOs. Based on the (Ed-there are no study results above) study results, the following suggestion were made. First, throughout the survey, it was found that those consumers who participated had a high level of perception on the harm of GMOs. Therefore, reliable organizations such as government agencies are required to present the results of safety tests and formulate plans related to the safety of GMOs. Second, the average score on consumers' level of consumer knowledge on GMOs was very low, being 1.68 out of a possible 8 points. Third, since women and housewives engaged in dietary habits and food had high demand for information on GMOs, it is necessary to provide women with information on GMOs. Fourth, since it is difficult to confirm the presence or absence of GMOs. in rapidly increasing demand for fast-food, it is necessary that consumers be provided with relevant information and make a reasonable judgement in purchasing food. Fifth, it is necessary to provide detailed regulations and measures for concrete contents and directions of information on GMOs. Sixth, it is necessary to provid information on GMOs from the commercial sources of information that are most preferred by consumers.

Recently, the publishing community now recognizes the importance of metadata in customers' buying decisions. As a result, they are more interested in effective metadata creation and quality maintenance, as well as standardization of exchanging system in the supply chain. As the library community also investigates the economic effectiveness of creating metadata, they try to find the best model for simplifying metadata creation by using sources close to the original. This study analyzes metadata work flow which had same source but be used in different fields by their own type and standard. It also discusses the same issues about each section and possibility about interoperation. Finally this paper tries to find an effective creation and distribution model of book metadata which can be used in domestic publishing and the library community.

Credit Bureaus in Korea commonly use financial transaction information of the past and present time for calculating an individual's credit scores. Compared to other rating factors, the repayment history information accounts for a larger weights on credit scores. Accordingly, despite full redemption of overdue payments, late payment history is reflected negatively for the assessment of credit scores for certain period of the time. An individual with debt delinquency can be classified into two groups; (1) the individuals who have faithfully paid off theirs overdue debts(Normal Repayment), and (2) those who have not and as differences of creditworthiness between these two groups do exist, it needs to grant relatively higher credit scores to the former individuals with normal repayment. This study is designed to analyze the factors of normal repayment of Korean financial debt delinquents based on credit information of personal loan, overdue payments, redemption from Korea Credit Information Services. As a result of the analysis, the number of overdue and the type of personal loan and delinquency were identified as significant variables affecting normal repayment and among applied methodologies, neural network models suggested the highest classification accuracy. The findings of this study are expected to improve the performance of individual credit scoring model by identifying the factors affecting normal repayment of a financial debt delinquent.

Geodetic Reference System was deferred from 2007 to 2010. Although National Geographic Information Institute in Korea takes charge of it, the progress is slow without clear policy alternatives. In this regards, this study aims at suggesting practical measures for introducing World Geodetic Reference System. Successful foreign countries have well established institutional system for improving their geodetic reference systems. In Korea, National Geographic Information Institute, Ministry of Maritime Affairs and Fisheries, and some municipalities have propelled introduction of the World Geodetic Reference System. However, none of them have systemical approaches. Although National Geographic Information Institute has conducted several researches regarding World Geodetic Reference System, comprehensive policy measures by central governments are not yet made. It suggests methods of data conversion, organizational structures, financial resources, and other supportive measures. Introduction of World Geodetic Reference System is nationwide project. However, there is not nationwide project promotion and management system yet. This research suggests overall policy frameworks to effectively propel World Geodetic Reference System.

This study is a new evaluation using the Arrhenius equation, which is known as the chemical reaction rate estimation equation, to evaluate the intrinsic and extrinsic value elements of patents as a model. The performance of the evaluation model was superior to the SVM, Logistic reg. and ANN models that were used as patent evaluation models in prior studies. In addition, there was a strong correlation between the predicted lifespan of the patent and the actual lifespan of the patent. These evaluation models may be used for evaluation purposes only, or if an evaluation is required, including a commercialization entity or technical characteristics.

Objective : To investigate the understanding of breast-feeding in pregnant woman and the proper way of encouraging breast-feeding. Methods : Each questionnaire included items about demographic characteristics and the understanding of breast-feeding. The questionnaires were filled up by pregnant women visiting obstetric clinics in Seoul and its vicinities, Busan, Choongjoo and Chungjoo from July 2001 to August 2001. One thousand, two hundred ninety questionnaires were analysed by Chi square tests and multiple logistic regressions. Results : The majority of pregnant women(87.4%) planned breast-feeding. Forty three percent of them had plans to breast-feed for 4-6 months. There were no differences in the level of education, the family size and the source of information about breast-feeding in planning to breast-feed (P>0.05). The main reasons for not choosing to breast-feed were returns to work(41.3%), previous failures of breast-feeding(17.4%), concerns about insufficient amount of breast milk(10.9%), breast and nipple problems(10.3%) and maternal illness(9.4%). The average score on the test of the understanding about breast-feeding was 59.7/100. The average scores on the understanding about the methods and advantages of breast-feeding were 45.3/100 and 86.1/100, respectively. The maternal status of employment, previous history of breast-feeding, the time of decision to breastfeed, person advocating breast-feeding and the understanding on the advantages of breast-feeding were significant determinant factors in planning to breast-feed(P<0.05). Conclusion : Pediatricians should take steps to make an effort to increase the breast-feeding rate and to encourage breast-feeding by timely education. Beyond the medical field, political and social supports for breast-feeding are urgently needed.

The purpose of this descriptive study was to investigate the level of cosmetic surgery experience, perception of side effects, self-esteem, acceptance of cosmetic surgery (ACS) and to explore factors affecting ACS among undergraduate students. A convenience sample of 255 students from three universities completed a self-administered questionnaire from May, 25, 2016 to May, 31, 2016. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation, and multiple linear regression. As a results, 11.5% of students had at least one cosmetic surgery and the majority of them had blepharoplasty. A total of 86.3% of students had heard of cosmetic surgery side effects and the most common source of information were TV, newspapers, magazines and internet. ACS was significantly different by gender, school year, perception of side effects, and cosmetic surgery experience. ACS and self-esteem showed a negative correlation. Previous experience of cosmetic surgery, self-esteem, school year, and gender were identified as influencing factors on ACS which explained 19.0% of total variance. In conclusion, to help college students make rational decisions on cosmetic surgery, provision of sufficient information, improvement of self-esteem, and introduction of gender and school year based intervention are recommended.
