The Effects of Apparel Product Presentation on Consumer Responses in U.S. Online Retailing
유정민,샤론레논 한국전자거래학회 2014 한국전자거래학회지 Vol.19 No.2
This study examined the effect of product presentation on consumers’ affective/cognitivestates and purchase intention. The design of the study was a one factor(product presentation:garment presented flat vs. garment presented on models without faces vs. garment presented on models with faces) between-subject design with a moderator(involvement: high vs. low). A sample of 429 female college students participated in thisonline experiment. The results show the effectiveness of using a realistic human modelon apparel websites. Also, consumers who are highly involved with clothing generallyexhibit more positive responses than those who are less involved. Overall, these findingsprovide empirical support for the Stimulus-Organism-Response model and the ElaborationLikelihood Model, and contribute useful knowledge regarding website design for onlineapparel retailers.

전치부 개교합을 가진 골격성 3급 부정교합 환자에서 하악의 반시계 방향 회전 시 술 후 안정성
유정민,유경선,이백수,권용대,최병준,김여갑,오주영,박성원,Ryu, Jeong-Min,Ryu, Kyung-Sun,Lee, Baek-Soo,Kwon, Yong-Dae,Choi, Byung-Joon,Kim, Yeo-Gab,Ohe, Joo-Young,Park, Seong-Won 대한악안면성형재건외과학회 2012 Maxillofacial Plastic Reconstructive Surgery Vol.34 No.4
Purpose: This study evaluated the postoperative stability of counter clockwise rotation of the mandibular plane in anterior openbite patients, who have had one jaw surgery performed. Methods: This study includes patients with skeletal class III malocclusion accompanied by anterior openbite among the patients who have had BSSRO performed, resulting in counter clockwise rotation of the mandibule. We excluded the patients with genioplasty and segmental surgery, and included 23 patients who underwent BSSRO. Results: We found no statistical significance between the amount of counter clockwise rotation in the mandible in the Pearson correlation test. Also, there was no significant difference between Group 1 (< $3^{\circ}$) and Group 2 (> $3^{\circ}$). Conclusion: This study evaluated the amount of horizontal relapse, and the degree of relapse. Stable results were obtained. Although there was no statistical significance between the degree of openbite and the amount of horizontal relapse, the group with a greater amount of openbite had a greater amount of relapse.

Purpose: Hemophagocytic syndrome (HPS) is characterized by persistent high fever, hepatosplenomegaly, cytopenias, hypertriglyceridemia, and/or hypofibrinogenemia. Hepatic manifestations including overt hepatic failure and fulminant hepatitis are common in HPS. Liver transplantation (LT) should be considered in a case of fulminant hepatitis by other than HPS, but LT is contraindicated and complete cure is possible by chemotherapy in HPS. Therefore, we conducted this study to define the characteristics of HPS presenting as severe acute hepatitis. Methods: Among the total of 23 patients diagnosed as HPS by bone marrow examination between 1994 and 2005 in Asan Medical Center, 11 cases presented as severe acute hepatitis were enrolled in this study. We analyzed the clinical features, laboratory findings and outcome retrospectively. Results: Seven (64%) of the 11 children with HPS and hepatitis were referred to pediatric gastroenterologist at first. The mean age of onset was 50 months. There was no case with family history of primary HPS. Epstein-Barr virus was positive in 4, and herpes Simplex virus was positive simultaneously in 1 case. As the presenting symptoms and signs, fever was present in 10, hepatosplenomagaly was noted in all and jaundice in 10. Anemia was observed in 10, thrombocytopenia in 10, leukopenia in 8, hypertriglyceridemia in 9, hypofibrinogenemia in 8 and hyperferritinemia in 7 cases, respectively. Nine children received chemotherapy including etopside. The overall mortality rate was 72% (8/11). Conclusion: HPS, which needs chemotherapy, should be considered as a cause of severe acute hepatitis especially when accompanied with prolonged high fever and cytopenias.

Design Concept Study of Kitchen Utensils for Single Household
유정민,김서영,나건 한국디지털디자인학회 2015 디지털디자인학연구 Vol.15 No.3
The purpose of this study is to suggest the design concept of kitchen utensils for single households. A Literature investigation had been taken to gain general knowledge about single households' lifestyle including their residential environment, consumption tendency and diet. Moreover, interview was conducted to find out single households’ unmet needs in their cooking process. Four pilot interviews were planned to gain specific direction for in-depth interview, and 14 cases of in-depth interviews were therefore produced. In order to analysis the in-depth interviews, K.J diagram was used to gain more specific and reliable quantitative data. Three keywords such as simplicity, comfort, and customizing are evaluated accordingly. As a result, single households’ cooking habit, pattern, and style could be analyzed. In conclusion part, kitchen utensils kit is suggested for the group who does not have strong interest on cooking, yet they rarely cook at home when necessary. Hence, further investigation to understand the taste of kitchen utensils is needed by considering its size, function, and performance in single households' cooking environment.

재무분석가의 수가 발생액 및 실제이익조정에 미치는 영향: 한-미 비교
유정민,윤금상,고재민,김동하 한국회계학회 2012 회계저널 Vol.21 No.5
재무분석가는 기업에 대한 분석 정보를 제공함으로써 경영자를 감시하는 역할을 수행하지만, 한편 그들이 제시하는 기대 이익은 시장의 압력으로 작용하여 이익조정을 유발하기도 한다. 본 연구는 이와 같은 상반된 논의에 기초하여, 재무분석가의 이익 예측 활동이 경영자의 이익조정에 어떤 영향을 미치는지 살펴보았다. 또한 자본시장의 발달 정도에 따라 재무분석가의 역할 수준이 달라진다는 선행연구에 근거하여, 재무분석가의 활동이 이익조정에 미치는 영향의 정도가 한국과 미국 자본시장에서 다르게 나타나는지를 분석하였다. 연구 결과, 한국과 미국 기업에서 모두 재무분석가 수가 증가할수록 재량적 발생액과 실제이익조정이 유의하게 감소하였다. 이는 재무분석가의 이익 예측 활동이 목표치를 달성하기 위한 시장의 압력으로 작용하기보다는 경영자에 대한 감시 기능을 수행하고 있는 것으로 해석할 수 있다. 그리고 한국과 미국의 이익조정 감시 기능을 국가별로 비교한 결과에서는 재무분석가의 수에 따른 발생액 이익조정과 실제이익조정의 감소 수준이 미국 표본에서 더 유의하게 높은 것으로 나타났다. 이것은 경영자의 재량적 이익조정에 대한 미국 재무분석가의 감시 기능이 한국에 비해 더 강한 것으로 해석되며 한국 재무분석가의 기능을 강화할 필요성을 제시한다. 본 연구는 그동안 한국 자본시장에서 재무분석가의 역할이 제한적이라는 주장을 실증적으로 확인한 데서 그 의의를 찾을 수 있다. 우리나라의 재무분석가들은 매도의견을 거의 제시하지 못하는 등 선진 시장에 비해 객관성과 독립성 등에서 열위에 있다고 알려져 있다. 따라서 한국 자본시장 내에서 재무분석가들이 정보 중개자 및 시장 감시자의 역할을 충실히 수행할 수 있는 체계를 보다 강화하는 것이 필요하다고 제안한다. Analysts’ forecasting activities generate a monitoring effect on managers’ opportunistic behavior, but the targets they set also put excessive pressure on managers to manage earnings. Under these circumstances, we tested the relationship between the number of analyst following and the levels of accrual-based and real earnings management in the Korean market and the US market in order to identify actual roles of analyst coverage on earnings management in each country, and find any difference in their roles between two countries. For the empirical tests, we used analyst forecast samples available in FnGuide(for Korean samples) and I/B/E/S(for the US samples) database during the period between 2004 and 2009. To avoid endogeneity problem, we first estimated unexpected analyst coverage residuals as proxy for the analyst coverage and used it for the main regressions. In the main analyses we individually regressed the impact of analyst coverage on accrual based and real earnings management in each country’s samples, and then regressed them altogether using interaction terms in order to compare the differences between Korea and the US. The empirical results show that the number of analysts gives a significantly negative impact on both types of earnings management from the Korean and the US samples. In addition, a significantly greater monitoring effect was found in the US samples than in the Korean samples. The results empirically evidences the limited role of analysts in the Korean market, which has been long criticized. This suggests that it is necessary to more systematically improve the analyst forecasting environment in the Korean market in order for the analysts to better perform their monitoring role as well as the role as information intermediary in the market.
