The hippocampus and prefrontal cortex are regarded as the highest-order association cortices. The hippocampus has been proposed to store "cognitive maps" of external environments, and the prefrontal cortex is known to be involved in the planning of behavior, among other functions. Considering the prominent functional roles played by these structures, it is not surprising to find direct monosynaptic projections from the hippocampus to the prefrontal cortex. Rhythmic stimulation of this projection patterned after the hippocampal EEG theta rhythm induced stable long-term potentiation of field potentials in the prefrontal cortex. Comparison of behavioral correlates of hippocampal and prefrontal cortical neurons during an a-arm radial maze, working memory task shows a striking contrast. Hippocampal neurons exhibit clear place-specific firing patterns, whereas prefrontal cortical neurons do not show spatial selectivity, but are correlated to different stages of the behavioral task. These data lead to the hypothesis that the role of hippocampal projection to the prefrontal cortex is not to impose spatial representations upon prefrontal activity, but to provide a mechanism for learning the spatial context in which particular behaviors are appropriate.propriate.

In the case of reinforced concrete structures, the knowledge of load transfer in the long-term behavior analysis considering construction sequence is very important. Even though long-term behavior of concrete structures has been widely studied, the studies on the time-dependent axial force variation of shore have been scarce to date. In order to investigate the shore behaviors under actual construction conditions, a three-story test frame was constructed on a construction site. The entire construction schedule for the test frame was made to follow the schedule of an actual three-story frame. To analyze the data collected from the test frame, an analysis method based on the Winkler foundation model was developed. This analysis method accurately Predicts the time-dependent behavior of shore. The analysis results coincide well with those obtained by the Midas GENw program

Long term stability, sensitization in air, and gas sensing behaviors of tin oxide films were investigated with doping of antimony and palladium. The tin oxide films were prepared on a Corning glass by reactive rf sputtering method and tested for detection of hydrogen gas. Sb-doping improved a long-term stability in the base resistance of $SnO_2$ film sensor. A small amount of Pd doping caused the optimum sensor operating temperature to reduce and also enhanced the gas sensitivity, compared with the undoped $SnO_2$ film. Gas sensitivity depended largely on the film thickness. The important sensitization reactions for sensor operating were $(O_{2ads})+e^-\;{\rightarrow}\;2(O_{ads})^-$ on the surface of $SnO_2$ film at elevated temperature in air and a followed reaction of hydrogen atoms with $(O_{ads})^-$ ions.

본 연구는 기업 구성원의 장기지향성이 변화 조직시민행동에 미치는 영향 및 감성활용의 매개효과를 살펴보았다. 홉스테드 연구에 의하면 동아시아국가 중 한국은 장기 지향성이 높은 국가로 나타났으며, 절약, 장기적 관계 및 소속된 집단의 화평을 중요하는 문화라고 볼 수 있다. 이와 관련 선행 연구들은 학교 및 국가별 차원에서 연구되었으며, 개인차원의 자발적 역량인 변화 조직시민행동에 미치는 영향을 검증한 연구는 많지 않다. 또한 글로벌 환경의 급격한 변화에 노출된 구성원들의 감성활용 능력은 조직의 구성원으론 매우 중요한 개인 역량으로 평가된다. 이런 현상을 바탕으로 본 연구는 대기업의 구성원들의 감성 활용 능력이 장기지향성과 변화 조직시민행동을 매개 할 것이라 예측했다. 본 연구는 홉스테드 문화차원을 개인적 차원으로 설문화한 Yoo's Cultural Value Scale (CVSCALE) 사용하여 통계프로그램인 SPSS 21.0을 통해 국내 S전자회사의 임직원 200명을 상대로 설문 및 분석했으며 결과는 다음과 같다. 장기지향성은 변화적 조직시민행동에 유의한 (+) 영향을 미친다고 나타났으며 개인의 감성활용이 장기지향성과 변화 조직시민행동을 완전 매개한다는 결과가 나타났다. 본 연구 결과를 통해 감성활용이 기업의 구성원의 변화 조직시민행동에 긍정적 영향을 준다는 점을 검증하였으며 구성원들의 감성 활용 훈련 및 교육을 통해 조직효율성을 높이고 자발적 행동역량인 변화적 조직시민행동도 높일 수 있다는 가능성을 제시한 점에 의미가 있다.

Objectives : The aim of this study was to assess the oral health care of the elderly in long-term care facility on caregivers' behaviors. Methods : Cross-sectional study in a cluster sample of 171 caregivers recruited from 17 facilities located in the Province of Gangwon. The Questionnaire was consisted of 16 items contained oral hygiene care, denture care, oral health education and general characteristics(Chronba's ${\alpha}$=0.87). Using SPSS WIN 12.0, descriptive statistics and chi-square test were conducted to examine the subjects general characteristics, the status of oral health education and denture care. Results : 1. The mean age of care givers was 42 years and 88.9% education experience rate was found. 2. Above 70% of them was found in daily oral hygiene care after every meal. They used toothbrush and toothpaste, they keep the toothbrush properly. 3. The denture care was conducted by most of care givers, containing proper storage. But three of ten care givers was cleaned denture by toothpaste or used water only. It was severe at the care givers didn't received oral health education(p<0.05). Conclusions : The contents of oral health education for care givers should contain the denture care(time and the reason shouldn't use toothpaste). Further large-scale longitudinal studies are needed to determine professional oral health care and to develop evidence of the dental hygiene practice for the elderly in long-term care facilities.

Understanding consumer complaining behaviors plays a key role in post-purchase satisfaction customer retention and long-term customer relationships. This research was conducted to empirically investigate 1) the taxonomy of complaining behavior 2) causes and types of clothing complaining behavior according to sex. The subjects compoed of 250 male and 358 female consuemrs. Data were colleted through questionnaires employing the critical incident methodology. The findings indicated that clothing complaining behavior was fitted well into Singh(1998)'s three-factor model(i. e. voice/private / third-party complaining behaviors) these factors explained 53% of the total variances 75.1% of male and 65.2% of female group complained of poor instruental performance. The types of complaining behaviors were no action negative word-of-mouth to friends and associates n order. Most dissatisfied consumers didn't assert positive consumer's right. Marketer should increase the accessibility of their complaint receiving mechanisms to passive customers.

The purpose of this study is to identify apparel consumers' immoral shopping behaviors from apparel retail sales associates' perspectives. As a first step to understand immoral consumer behaviors in apparel retail setting, the study took an exploratory approach using five focus-group interviews with 35 apparel salespeople. The immoral behavior of fashion (product) consumers was divided into two categories: one was the immoral behavior associated with the product, and the other was the immoral behavior relative to the consumer. The immoral behavior associated with the product was classified into three types: shoplifting, inappropriate returns, and damaging to merchandise. Immoral behavior relative to the consumer was classified into two types: abusive behavior by a consumer toward sales associates and excessive demand. Although, shoplifting was the primary immoral behavior mentioned by all interview participants, most sales associates failed to recognize shoplifting as a serious criminal behavior. Another commonly mentioned immoral consumer behaviors was retail borrowing, which may pose serious problems to the fashion industry. The findings of this study will provide a basis for approaches that may help decrease immoral consumer behavior at fashion retail stores and provide a basis for developing materials for consumer education over the long term.

This study aims to examine the influence of growth rate, profitability and current ratio, which are confronted with static trade-off theory and pecking order theory, on capital structure of superior hospital and bankrupt hospital. Firstly, superior hospitals show positive correlation between growth rate and short-term loans, long-term loans, and short-term liabilities while bankrupt hospitals represent negative correlation. Superiority hospital and bankruptcy hospital show different financing behaviors, especially, short-term loan is the significant characteristic that discriminates between superior hospital and bankrupt hospital. Secondly, this paper studied the correlation between profitability and short-term loan, which the superior hospitals shows negative correlation, to contrast, bankrupt hospital have positive correlation. Consequently, the short-term loan is the most distinguishable factor between the superior hospital and bankrupt hospitals in terms of profitability. To conclude, this study shows that excess short-term loans can be the most important cause for hospital's bankrupt. Accordingly, strategic and effective policy about the short-term loan will be required in order to protect hospital's bankrupt.
