본 연구에서는 소유효과(endowment effect)와 손실회피(loss aversion)성향에 기인한 판매자의 판매용의가격(willing-to-sell price: WTS)과 구매자의 지불용의가격(willing-to-pay price: WTP) 간의 차이에 관한 기존 연구를 최근 점점 더 소비자들이 경험하고 있는 새로운 유통경로인 온라인 경매라는 거래상황에서 재검증하였으며, 동시에 이러한 판매자와 구매자의 용의가격의 차이에 조절적 영향을 주는 요인으로, 이득(gain)과 손실(loss)에 대한 소비자들의 휴리스틱적인 성향과 관련된 기존 연구결과들을 바탕으로 하여, 제품 유형(product type)과 소비자가 가지고 있는 목적 지향성(goal orientation)이라는 추가적인 조절변수들의 효과를 살펴보았다. 실험결과, 기존연구와 마찬가지로 판매자들이 제시하는 용의가격(WTS)이 구매자들이 지불하고자 하는 용의가격(WTP)보다 높았으며, 이 두 가격의 차이는 거래되는 제품이 소비자의 입장에서 실용적인(utilitarian product) 가치를 갖는 제품일 때보다 쾌락적인(hedonic product) 가치를 갖는 제품일 때, 또한 거래에 참여한 소비자가 향상 목적(promotion goal)을 가지고 있을 때보다 예방 목적(prevention goal)을 가지고 있을 때 더욱 두드러지는 것으로 나타났다. 마지막으로, 본 연구결과의 이론적 및 실무적 시사점, 그리고 본 연구의 한계점 및 향후 연구방향에 대해서 논의하였다.

손실회피에 대한 연구는 많은 진보가 있었다. 특히 Brenner et al. (2007)은 소유손실회피 (possession loss aversion: PLA)와 유인가손실회피 (valence loss aversion: VLA)의 상황을 구분하면서 현금과 현물 (돈, 부동산)에 대한 손실 (PLA)과 잠재적으로 획득할 가치 (해외연수, 쿠폰)에 대한 손실 (VLA)에 대한 사람들의 반응이 어떻게 다른지 관찰하였다. 그러나 일상생활에서 소유와 유인가의 득과 실이 명확하게 구분되는 경우는 드물고, 대부분 소유와 유인가의 득과 실 사이에 일장일단이 있어, 결국 사람들이 평소 가지고 있는 사고방식이나 주의의 초점이 의사결정에 반영되는 경우가 더 많다. 따라서 본 연구는 사람들이 평소 어디에 주의를 기울이는지에 따라 손실회피의 반응이 어떻게 달라지는지 살펴보고자 했다. 구체적으로 자기초점을 촉진초점 또는 예방초점으로 점화한 후, 이직결정상황에서 소유와 유인가의 득실이 경쟁 (연봉증가 해외연수기간감소: P+V-, 연봉감소 해외연수기간 증가: P-V+)할 때, 이직할 것인지 여부를 결정하는 과제를 수행하였다. 결과적으로 촉진초점의 경우 소유인지 유인가 인지에 관계없이 잠정적으로 얻게 될 이익 (+)에 주의를 기울인 결과 이직하겠다는 응답이 증가한 반면, 예방초점의 경우 잠정적으로 감수할 손실 (-)에 주의를 기울인 결과 현재 회사에 머물겠다는 응답이 증가하였다. 본 연구의 결과는 소비자 및 광고심리와 마케팅분야에 폭넓은 시사점을 가진다.

This study is to conducted to find out parents' level of knowledge on child sexual abuse prevention, and their demands for a parental education program on sexual abuse prevention. Two hundred and six parents of 5 to 7 year-old children in kindergartens in Kwangju and Chonnam were surveyed. Data were analyzed by using frequencies and percentages. The results are as followed Parents have obtained knowledge on sexual abuse through mass media, guiding books and so on. They were aware that communication with children is the most effective method for sexual abuse prevention. They were somewhat at a loss on exactly what to teach and how to teach the children. and complained about the lack of educational materials. They think that the age that is most appropriate for such education is between 6 and 7 year-old, and the parents and teachers are responsible for educating chi10en on sexual abuse. For the desired content of the education, they included sex, sexual abuse, and parents' coping.

이번 연구에서 우리는 6종의 미세조류 ; Phaeodacylum tricrnutum (PT), Chaetoceros gracilis (CG), Nanochloris oculata (NO), Pavlova lutheri (PL), Chlorella ellipsoidae (CE), and Scendedemus obliquus (SO)를 이용하여 탈모 예방 및 두피 개선효과를 살펴보았다. DPPH 라디칼 소거능 실험에서는 SO, CG, ST9 순으로 활성이 높은 것으로 나타났다. OH 소거능 실험 결과, CG (6.6~42.1%), ST9 (26.0~44.0%), SO (7.8~44.3%)으로 유의적인 효과를 보였다. 그외에도 세포증식실험에서는, SO가 인간표피세포주인 HaCaT 세포 증식을 촉진시켰으며, CG와 SO가 모유두세포주인 HFDPC 세포 증식을 촉진시키는 것으로 나타났다. 마지막으로 5-alpha reductase 저해능 실험결과, PT, CG, SO가 유의적으로 효소활성을 저해하였다. 따라서, 이번 연구에 사용한 6종의 미세조류들 중, 항산화활성, 세포증식 효과, 5-alpha reductase 저해능을 보인 몇가지 조류들이 탈모예방 및 두피개선을 위한 제품개발에 좋은 원료가 될 가능성이 있음을 제시한다.

Salmonella is one of the most important food-borne zoonotic pathogens, causing acute or chronic digestive diseases such as enteritis. The acute form of enteritis is common in young pigs of 2 - 4 months of age. The main symptoms include high fever ($41-42^{\circ}C$), loss of appetite, and increased mortality within 2 - 4 days of onset of the disease. It is often the cause of increasing mortality, decreasing growth rate and reducing feed efficiency of piglets. In the case of chronic enteritis in pigs, the main symptom is weight loss due to the continuing severe diarrhea. Salmonella enterica serovar Typhimurium and Salmonella enterica serovar Choleraesuis are typical pig adapted serotypes, which cause one of four major syndromes: enteric fever, enterocolitis/diarrhea, bacteremia and chronic asymptomatic carriage. These syndromes cause a huge economic burden to swine industry by reducing production. Therefore, it is necessary that swine industries should strive to decrease Salmonellosis in pigs in order to reduce economic losses. There are several measures, such as vaccination to prevent salmonellosis, that are implemented differently from country to country. For the treatment of Salmonella, ongoing antibiotic treatment is needed. However constant doses of antibiotics can be a problem because of antibiotic resistance. Therefore, the focus should be made more on prevention than treatment. In this review, we addressed the basic information about Salmonella, route of infection, clinical symptoms, and prevention of Salmonellosis.

The extreme weather events have increased around the world this century. One of the main reasons of frequent occurrence is the change of atmospheric circulation by El nino. also Korea Peninsular is not exception. The 97 % of death toll and 89 % of property loss of total are related with extreme-weather events for the last 10 years. for example the heavy rainfall (1998-4999) and Typhoon Rusa and Mamie. In spite of the percent of death toll by extreme-weather disaster is increasing and the total population is growing. but the number of death toll from natural disasters is decreasing. It shows that the loss of property and life can be minimize by preparing the proper disaster prevention measures. There are several preparations to reduce the damage by extreme-weather events: Public facilities have overall check up, to recognize the weather alert, the awareness of the escape route and the art of measures

Background: Nasopharyngeal carcinoma (NPC) is an aggressive disease and tends to involve surrounding tissues, and biomarkers for better management are yet to be identified. Materials and Methods: One hundred and fifty tissue samples with NPC diagnosis were were investigated using pan cytokeratin (CK) and epithelial membrane protein 2 (EMP2) antibodies. Results: Immunohistochemical expression of CK was identified in 144/150 (96%) and of EMP2 in 120/150 (80%). Conclusions: There is a high loss of EMP2 in NPC, especially high grade examples. Loss of CK expression is also linked to high grade NPC types.

Objectives: To evaluate the safety, efficacy, and invasiveness of lobectomy by video-assisted thoracoscopic surgery (VATS) in the treatment of stage I/II non-small cell lung cancer (NSCLC). Methods: A total of 148 patients presenting with Stage I or II NSCLC were enrolled into our study, comprising 71 who underwent VATS and 77 patients undergoing conventional thoracotomic lobectomy, in combination with systematic lymph node resection. Results: It was found that VATS was superior to conventional thoracotomy in terms of the duration of surgery, intraoperative blood loss, frequency of the need to administer postoperative analgesia, thoracic intubation indwelling time, post-operative hospital stay, and survival rate (P<0.05). We saw no obvious difference in the number of resected lymph nodes with either approach. Conclusions: VATS lobectomy is a safe and reliable surgical approach for the treatment of Stage I/II NSCLC, characterized by significantly minimal invasiveness, rapid post-operative recovery, and markedly lower loss of blood.

The industrial accident in subway of late is increasingly coming to the front as a serious problem of society because a scale of industrial accident is a large size, and powerfulness, while the percent of accident is decreasing as a result of industrial facilities with the largeness of equipment, automation, and high horse-powering. In this paper, a study on the estimation of accident loss prevention cost and risk analysis in subway construction is proposed as an alternative to the techniques currently used in the general construction projects safety. Then the concept of risk evaluation using a risk assessment model is presented to drive value of risk and numerical example for risk analysis. A means for this does grasp the importance of educational factor by way of analyzing the causes of accident through statistical data of labor department, emphasizing the necessity and the importance of safety education, being helpful to act safety by decreasing insecure activity which ranks the majority of accident causes with putting the education program, form, method into practice that are suitable for a place of business.
