  • Roll의 비판 이후 실행된 많은 국내외 연구결과 CAPM으로 설명이 되지 않는 이례 현상(Anomaly)들이 발견되고 있다. 이례 현상들은 다 요인 모형(multi-factor model)과 같은 추가 위험 요인이론, 표본차이이론, 과잉반응 및 특성이론들로 설명되고 있고 이러한 이례 현상들은 재무관리의 지속적인 관심사인 미래의 주가수익률 예측과 밀접한 관계에 있다. 본 연구에서는 이례 현상들이 주가수익률에 미치는 영향을 알아보기 써하여 Haugen and Baker(1996)의 다 요인 및 수익률 추정 방법론을 국내 증권시장에 적용한 다 요인 모형과 $\beta$, 기업규모, PBR, 과거 1년 주가 수익률에 의한 단일 요인 모형을 이용하여 개별 기업의 포트폴리오 구성기준을 결정하고 이 기준에 의거하여 월별로 편입 주식들을 재조정한 포트폴리오들의 년간 누적 실제수익률 예측력을 비교 분석한 결과 다음과 같은 결과를 얻었다. 첫째, 다 요인모형의 경우 기대수익률이 높은 주식으로 구성된 포트폴리오가 기대수익률이 낮은 주식으로 구성된 포트폴리오보다 실제 년간 수익률이 높게 나타난 반면, $\beta$, 기업규모, PBR, 과거 1년 주가 수익률의 요인에 의한 단일 모형을 적용한 포트폴리오는 이들 순위와 실제 수익률간에는 상관성이 높지 않게 나타나 다요인 모형이 주가 수익률 예측력에 있어서 단일요인 모형보다 우수한 것으로 판단된다. 단일모형 중에서는 PBR을 이용한 포트폴리오가 $\beta$ 단일모형보다 좋은 주가수익률 예측력을 보여 주었다. 둘째, 주가 수익률을 결정하는 유의성있는 요인들은 당기순이익의 증감, 당해연도의 당기순이익의 분포, 자산증가율, 매매 유동성, 매출액 변동, 거래량 추세, 기업크기(시가총액), 과거 1개월간의 주가수익률, 자기자본증가율등으로 나타났다.

  • The purpose of this study is to examine the relationships among the factors affecting unanswered reference/information service and to suggest alternative steps which would overcome the unsatisfactory outcome in reference/information service policy. A questionnaire on the quality of reference/information service was developed to survey librarians and users in 10 different private and national university libraries. About half of 500 responses indicated dissatisfaction with the reference/information service and 10 variables were eventually identified as the primary factors which have significant relationships with users's satisfaction. Collection variables were identified as major factors associated with the unanswered service but the analysis of each factor's influence on a reference/information transaction has shown that there exist significant relationships among variables of librarian and environmental variables and the users' satisfaction. Tiered or non-tiered reference/information service showed positive relationships with collection and environmental factors.

  • This study examined the factors affecting the preference for the elderly's mental health services utilization in rural areas. A behavior model developed by Andersen and Newman provided an analytical framework to determine the factors affecting service utilization preferences among 335 elderly people as research subjects. The authors found that the preferences for mental health service utilization were significantly related to the level of education, living alone, presence of grandchildren, participation in social activities, and recognition about the services. Based on the findings, this study suggests that more mental health services for the elderly in rural areas be further developed and strengthened. Also, the elderly who lives alone and lives with grandchildren should have a priority in policy consideration. Multiple approaches are suggested to increase the awareness of mental health services and participation social activities for those older people.

  • This study was carried out to establish an effective marketing strategy based on Importance-Performance Analysis (IPA) of rice-convenience foods. IPA is one of the most efficient and simple methods to evaluate product quality. Data were collected from 652 people (320 males and 332 females) and analyzed by SPSS 19.0. Subjects consumed rice-convenience foods as a snack substitute (19.3%), breakfast (20.7%), lunch (37.4%), dinner (15.2%), and late-night meal (7.4%). The purpose for consumption of rice-convenience foods were as follows: light meal (34.8%), lack of time to prepare meal (42.2%), favorite restaurant is not nearby (2.3%), save money (3.4%), and outdoor activities (9.7%). All attributes about rice-convenience foods were categorized into intrinsic property and extrinsic property. As a result of factor analysis, health, sensibility, and diversity factors were extracted from intrinsic property. In addition, dependence and appearance factors were drawn from extrinsic property. In analyzing the differences between importance and performance, there were significant differences; 16 items in the intrinsic property (P<0.01), and 10 items in the extrinsic property (P<0.001). The IPA matrix is composed of four quadrants, and each represents different strategies; the first, 'keep up the good work', the second, 'possible overkill', the third, 'low priority for management', and the fourth, 'concentrate management'. As a result, factors of rice-convenience foods positioned in the fourth quadrant were 'safety (from food additives, etc.)' and 'price' in the intrinsic property and 'nutrition label' and 'safety of packaging material' in the extrinsic property. They need to be improved immediately. In this study, rice-convenience food factors for continuous maintenance and concentrative improvement were compared by IPA. Based upon the results of this study, it is necessary to develop methods to make efficient use of limited resources and practical marketing strategies.

  • The purpose of this study was to improve satisfaction of university dormitory foodservice customers by analyzing the correlation between foodservice satisfaction and customer loyalty. The questionnaire was distributed to 510 students residing in a dormitory of a University located in Gyengsangbuk-do from 1st to 8th December, 2015. The average customer satisfaction score was 3.19/5.00. The category with the highest score was sanitation, followed by environment, food, reactivity, and menu. Male students showed significantly higher foodservice satisfaction score than females in terms of reactivity (P<0.01) category. Students living in the dormitory for over 2 years were significantly less satisfied with the dormitory foodservice in terms of menu (P<0.05) and reactivity (P<0.001) categories. The average customer loyalty score was 2.73/5.00. Scores for revisit intention, words-of-mouth intention, and intent not to switch were 2.80, 2.73, and 2.65, respectively. Revisit intention and words-of-mouth intention showed a significant (P<0.001) positive correlation with food, environment, menu, sanitation, and reactivity. Non-switching intention showed a significant (P<0.001) positive correlation with food, menu, and reactivity. After classifying customers into four groups according to customer satisfaction and loyalty, a comparison was carried out to determine satisfaction and loyalty by each customer stratum. In the "loyalist" group, satisfaction with sanitation and the advertise intention by revisit and words-of-mouth were significantly higher than in the other groups (P<0.001). In "defector" group, satisfaction with menu (P<0.001) and advertise intention by words-of-mouth (P<0.01) were significantly lower than in the other groups.

  • The progress of Information Technology enables people can communicate each others using the Internet. As a smartphone proliferates, many free mobile VoIP(Voice over IP) application are developed and accepted by smartphone users. In this study we investigate the factors affecting the acceptance of mobile VoIP applications and the structural relationship among these factors. We review the related works and extract the related factors and build a research model describing the causal relationship among these factors. We conduct an empirical study - a survey and statistical analysis - to verify the research model. EFA(Exploratory Factor Analysis) is applied for variables in the survey and SEM(Structural Equation Model) is used to reveal the structural relationship among the factors. We can find that two factors - usefulness of mobile VoIP and social influence - positively affect usage intention and actual use. These findings imply that it is required to emphasize the benefits of mobile VoIP use and add S/W functionalities enhancing social influence.
