Purpose - The purpose of this research is to discover whether the presence of the product average rating introduces biases or change the way people perceive information. We posit that review's overall rating has a predisposition effect on consumers' perception towards detailed review information. Research design, data, and methodology - To test these hypotheses, we conducted an empirical study on a real-world setting of online shopping platform. We choose the Amazon website to test our results. The data we use were collected by the Stanford Network Analysis Project1 (McAuley et al., 2013). Results - With a dataset containing reviews of seven product categories from amazon.com., our findings could possess more generalizability as they are produced on the typical and influential online market. Second, as our research provides alternative views of consumers' shopping behavior, it is better to test our hypotheses by data from the same source. Conclusions - Our study reveals the impact of the collective rating presence on consumers' diagnosticity perception and sheds light upon some of the conflictive results in prior studies. Our research generates implications to both theories and business practices, and suggests future directions for the research question.

Infants born small for gestational age (SGA) are at increased risk of perinatal morbidity, persistent short stature, and metabolic alterations in later life. Recent studies have focused on the association between birth weight (BW) and later body composition. Some reports suggest that fetal nutrition, as reflected by BW, may have an inverse programing effect on abdominal adiposity later in life. This inverse association between BW and abdominal adiposity in adults may contribute to insulin resistance. Rapid weight gain during infancy in SGA children seemed to be associated with increased fat mass rather than lean mass. Early catch-up growth after SGA birth rather than SGA itself has been noted as a cardiovascular risk factor in later life. Children who are born SGA also have a predisposition to accumulation of fat mass, particularly intra-abdominal fat. It is not yet clear whether this predisposition is due to low BW itself, rapid postnatal catch-up growth, or a combination of both. In this report, we review the published literature on central fat accumulation and metabolic consequences of being SGA, as well as the currently popular research area of SGA, including growth aspects.

본 실험중 이병성품종인 Khao-tah-haeng 17에서는 4개 접종전처리온도어디서나 접종에 사용된 6개 균주에 대하여 저항성보다는 이병성병반이 많이 나타났다. Tetep, Carreon, IR36 및 Sensho에서는 이병성병반 보다는 저항성병반이 많이 나타났다. 저항성 및 이병성병반수 공히 접종전 처리온도간, 공시종간에 고도의 유의성이 있었다. 특정품종에서 이병성병반의 발현은 접종전처리온도와 두열병균균주에 의해서 좌우되었으며 저항성병반의 발현은 접종전처리온도보다는 도열병균균주에 의해서 좌우되었다.

Motivation and learning strategies, some of the important factors affecting language learning, have mostly been studied with reference to their relationship in terms of proficiency. This study investigated motivation and learning strategies and their relationship in order to find the inward predisposition of learners. Data was collected from 200 university students in Taejon and Chungnam province, Korea language learning strategies were measured by the Strategy Inventory for Language Learning(SILL), and motivation by the Attitude / Motivation Test Battery(AMTB), with adaptations for Koreans. The detailed analysis of the data Indicated that Korean university students were more motivated to learn English for a practical goal than a formal one. They had a strong willingness to learn but showed 'the tendency of the new generation' of choosing the easiest and most convenient ways in studying English in terms of motivational intensity and strategy use. Findings imply that there have to be some changes and improvements in the deep-rooted classroom teaching methods. A systematic device is needed to induce students to be autonomous learners, providing them with a variety of activities suitable for their purposes and levels, as in opportunities of contacting native speakers, multi-media language labs, the Internet etc.

This study investigates the relationship between family ownership and the stock price crash risk. It believes that this relationship would never be in direct connection. The authors design and then find that family ownership is predisposed, in the first place, to the related party transaction, then the related party transaction causes the future stock price crash. This study infers that employing the power of family ownership creates the Type I agency problem, although this is not relevant for the Type II problem. From the perspective of the hoarding theory, family ownerships produce opaque accounts by blurring financial information. The blurred information is probably hidden in the related party transactions. This study, therefore, splits these transactions into accounts receivable, other accounts receivable and other receivables. Finally, this research concludes that the family ownership affects related party transactions. These then are used as an instrument to influence the leaded related party transaction. The latest, leaded related party transactions influence the future stock price crash. This study infers that related party transactions are abusive practices, especially on the types of receivables. It implies corporate governance's revitalisation.

이 연구는 온라인 포털 뉴스에 대한 혐오성 댓글의 제3자 효과를 분석하였으며, 특히 뉴스 이용자의 성향에 따라 제3자 효과가 어떻게 달라지는지 살펴보았다. 구체적으로 이주민의 불법체류에 관련된 뉴스 댓글을 혐오성 댓글과 이성적 논조의 댓글로 나누어 댓글 속성, 즉 표현방식에 따른 제3자 효과를 온라인 실험연구를 통해 비교하였다. 그리고 이용자의 이념적 성향과 이주민에 대한 차별적 성향에 따라 혐오성 댓글의 제3자 효과가 어떤 차이를 보이는지 분석하였다. 479명이 온라인 실험에 참가하였으며, 실험참가자는 혐오성 댓글(실험집단)과 이성적 댓글(통제집단)에 무작위로 할당되었다. 연구 결과, 진보적 성향의 뉴스 이용자는 혐오 표현 유무와 관계없이 전반적으로 제3자 효과가 높게 나타났지만, 보수적 성향의 이용자는 혐오성 댓글에서만 제3자 효과가 높게 나타나는 것을 확인하였다. 전통적으로 제3자 효과 연구는 주로 매스미디어를 대상으로 이루어졌는데, 이 연구는 이러한 효과 이론을 이용자의 댓글이라는 새로운 현상에 적용하고, 이 효과가 뉴스 이용자의 이념적 성향, 다문화에 대한 차별적 태도 등 이슈와 밀접하게 관련된 개인적 특성에 따라 어떻게 불균등하게 발생하는지를 살펴보았다는 점에서 의의가 있다.

The gut mucosal barrier plays an important role in maintaining a delicate immune homeostasis. The pathogenesis of inflammatory bowel disease (IBD) is considered to involve a defective mucosal immunity along with a genetic predisposition. Recent views have suggested an excessive response to components of the gut microbiota in IBD. A condition of "dysbiosis", with alterations of the gut microbial composition, has been observed in patients with IBD. In this article, the author review recent studies of gut microbiota in IBD, particularly the importance of the gut microbiota in the pathogenesis of pediatric IBD.

A retrospective study on 72 dogs with demodicosis, presented to Veterinary Teaching Hospital of Chonnam National University between 1987 and 1996, is reported. About 18% of the dogs with skin disease had demodicosis. About 75% of the patients with demodicosis were purebred dogs, and the short-haired breeds had a much higher incidence than do long-haired breeds. The age of the patient ranged from 1 month to 3 years, and about 63% of the patients were less than a year of age. Sex and seasons have been shown to have no effect on the development of demodicosis. A hereditary predisposition of generalized demodicosis has been observed from an affected litter.

A two-month-old female Thoroughbred foal was referred to the Equine Hospital, Jeju Stud Fm, Korea Racing Association. The foal was presented with opening of the abdominal ring by congenital predisposition. In physical examination, the foal revealed a mild heating, fluctuant swelling at umbilicus. The umbilical hernia was diagnosed, and then modified umbilical herniorraphy was performed and resulted in successful treatment. We conclude this method is of great value within the six-month-old foal with hernial ring size less than 10 cm.

The PTEN tumor suppressor is mutated in diverse human cancers and in hereditary cancer predisposition syndromes. PTEN is a phosphatase that can act on both polypeptide and phosphoinositide substrates in vitro. The PTEN structure reveals a phosphatase domain similar to protein phosphatases but having an enlarged active site important for the accommodation of the phosphoinositide substrate.(omitted)
