The relationship of information flow and market price formation are central to the basic tenets of financial economics. Whereas information is usually treated as being either public or private(monopolistic), most empirical studies focus on the price effects of public announcements. More recent research has centered more on the role of private information, such as insider trading, in efficient pricing and whether such trading increases investor welfare. Typically, 'insider trading' refers to an officer that trades in his/her company's shares. Insider trading, however, also refers to anyone who generates private, albeit costly, information concerning a stock's fundamental value. Normally, such insider activity is more difficult to ascertain. One way in which negative information is revealed is through short-selling activity, especially the monthly short-interest positions reported by the national stock exchanges. Diamond and Verrecchia(1987) provide a theoretical paradigm that predicts a negative price adjustment upon announcement of n company's monthly short interest, if the short interest displays an unusual increase and is correlated with negative information that is not yet public. Empirical studies of the short-run, negative price effect predicted by Diamond and Verrecchia find mixed results. One explanation is that the time period studied is too short for the market to absorb the informational content of these announcements. One reason is that these announcements are an ambiguous signal that requires more individuals and time to collect and act on the same information before full revelation occurs or before the implicit information becomes publicly known. This 'long delayed reaction' also serves as a motivation for related research on the wealth effect of mergers, share repurchases, and initial equity offerings in which long-run performance differs from the initial, short-run reaction to such announcements or offerings.

The purposes of this study are to identify the relationships between service quality, perceived value, satisfaction, and loyalty for IhoTewoo festival through a structural equation model. This study was conducted by means of survey questionnaire of festival visitors with 348 responses. The main results of the study are as follows. First, the exploratory factor analysis with principal component method of the 19 service quality items identified four underlying domains. These dimensions were labelled: (1) 'program', (2) 'informational service', (3) 'festival area', and (4) 'food'. Second, service quality has a significantly positive effect on perceived value, satisfaction, and loyalty. Third, Perceived value has a significantly positive effect on satisfaction. Fourth, both perceived value and satisfaction have significantly positive effects on loyalty. Fifth, Although the direct effect of service quality on customer loyalty was evident, it was also found that the indirect effects of service quality through perceived value and/or overall satisfaction were stronger. Thus, customer loyalty will be stronger when service quality is matched with perceived value and/or overall satisfaction, meaning that multiple factors play a significant role in determining customer loyalty.

Consumers are prone to engage in browsing because they are, for a variety of reasons, open to spending opportunities that grab their attentions. In-store browsing is the in-store examination of a retailer's merchandise for recreational or/and informational purposes without an immediate intent to buy. Browsers made more unplanned purchases than non-browsers in a regional mall setting. As a form of on-going search, in-store browsing is a central component in the impulse buying process. The purposes of this study were 1) to examine the causal relationships among fashion involvement, hedonic consumption, browsing and impulse buying behavior, and 2) to investigate the mediating effects of browsing on impulse buying behavior for fashion products. A questionnaire was developed from a literature review and measured on a 7-point rating scale. Data were obtained from 413 students attending universities in Busan. The self-administered questionnaire was given during a scheduled class. Using structural equation modeling, the results indicate that the proposed model of this study is appropriate to explain the mediating effects of browsing on impulse buying behavior for fashion products. The model shows that fashion involvement and hedonic consumption are important as antecedents of browsing in fashion stores, and consumers browsing longer in fashion stores would tend to increase the likelihood of experiencing impulse buying behavior. That is, browsing in store plays an important mediating role in triggering impulse buying behavior for fashion products. The results from this study provide some insights into retail marketing theory supporting the trait and behavioral aspects of impulse buying. Future research and managerial implications are addressed.

Few studies have examined the relationship between social support and stages of adoption of cancer screening. Here we investigated associations between both structural and functional aspects of social support and stages of adoption of gastric cancer screening in the general population of Korea. The study population was derived from the 2011 Korean National Cancer Screening Survey (KNCSS), an annual cross-sectional survey that uses nationally representative random sampling to investigate cancer screening rates. Data were analyzed from 3,477 randomly selected respondents aged 40-74 years. Respondents were classified according to their stage of adoption of gastric cancer screening: precontemplation (13.2%), contemplation (18.0%), action/maintenance (56.1%), relapse risk (8.5%), and relapse stage (4.1%). Respondents with larger social networks were more likely to be in the contemplation/action/maintenance, or the relapse risk/relapse stages versus the precontemplation stage (OR=1.91, 95%CI: 1.52-2.91; p for tend=0.025). Emotional and instrumental supports were not associated with any stage of adoption of gastric cancer screening. However, respondents who reported receiving sufficient informational support were more likely to be in the relapse risk/relapse stages versus the precontemplation, or the contemplation/action/maintenance stage (p for trend=0.016). Interventions involving interactions between social network members could play an important role in increasing participation in gastric cancer screening.

The object of this study is to examine the informational effect of the rating change announcement on the capital market. For this study, daily stock prices from January 1993 to February 2001 and daily bond prices from July 2000 to February 2001, for the bond market are used. In the stock market, we could not observe any statistically significant stock price reaction to rate change announcements from July 2000 to February 2001. However, if rating agencies announce more than two degradation for the period of January 1993 to February 2001, statistically negative significant stock price reactions are observed. On the other hand, there is no statistically significant stock price reaction to any other rating change announcement. In the bond market, there is no statistically test on the bond price reaction, but the general directions of bond price movements are consistent with the effect we can expect from rating change announcements. Generally, when the rating agencies degraded more than two grades at once, a cumulative abnormal returns move negatively during the overall period. In this case, we can say that rating agencies' role is to confirm information or investor's expectations. However, for the other cases, we could not observe my significant movement before or on the event data.

A department homepage contains various informations related with the department. So, a role of the department homepage is very important for both of students and applicants. For this reason, D university is evaluating the homepages of all departments in viewpoint of the construction, design, and contents of homepage. But the method of this homepage evaluation has some problems. Therefore, in this study, we propose a objective index for department homepage evaluation which can be applied to homepages of the other departments. Also we expect to provide an important information for the efficient homepage management by using the proposed index for homepage evaluation.

The purpose of this study is to analyze ego state types of teacher librarians by using egogram of the Transactional Analysis. It is the ideal ego state types for teachers that NP (Nurturing Parent), A (Adult) and FC (Free Child) are much higher than CP (Critical Parent) and AC (Adapted Child). But the teacher librarians are under higher CP and AC rather than A and FC. It means that the teacher librarians consider their values and belief as right things. Also it seams that they have not a conciliatory attitude but a hardened attitude that emphasize rules and standards. These ego state may be obstacle to their instructors role under the constructivist learning environment highlighting self directed learning of students. So, in the training course for the teacher librarians, informational and educational service course and development programs of education contents and instructional materials should be reinforced in order to strengthen their teaching competence and partnerships.

In spoken language, the characteristics of prosodic realization are related to the meaning of utterance. The pitch pattern of an interrogative sentence which differs from that of declarative sentences can be considered in this respect.. If we consider the question-answer pair, we can find that the most important variation comes from the intended meaning of asking. In this paper, we experiment with four kinds of interrogative sentences and show that the difference in pitch patterns of interrogative sentences can be explained in relation to the focus phenomena that is, the differences of the boundary tones in interrogative sentences are due to the differences in the prosodic domain of focus. For a relevant explanation with the focus phenomena, we divided focus into the categories: emphatic focus, which plays a role in delivering the speaker's intended meaning for the sentence interpretation, and informational focus, delivers the central intended meaning of the utterance. The results can be summarized in three points. First, High boundary tone delivers the meaning of asking. Second, the realization of different boundary tones that are found in wh-question and alternative question are just phonetic variations caused by focusing. Third, the high rise boundary tone in echo questions is related to the meaning of surprise or incredulity, and this relation is a consensus of existing opinion, that is, the speaker's attitude of surprise can raise the pitch range. From these results we can distinguish between boundary type and phonetic variation, and we can also give appropriate meaning to the different boundary tones in interrogative sentences that have been regarded as merely a part of sentence type.

Social support may play an important role in relieving the feelings of guilt and shame of unwed mothers due to social insults and ignorance and in helping them from physical and psychological harm caused by them. In addition hope may encourage to seek out a new way of life. To determine if a relationship between perceived social support and hope exists in unwed mothers a descriptive study was conducted in the facilities providing basic data for promoting the health of unwed mothers. A demographic data sheet and two instruments were used : Indirectly Perceived Social Support Scale(IPSSS) developed by Park Jee Won (revised by Jo Moo Yong), Miller Hope Scale(adapted and revised by Lee Mi Ja), 95 unmarried mothers participated. The mean score of perceived social support was 3.17. Family support was the highest(3.47) and unwed father support was the lowest(2.53) in sub-scales. Material support(3.53) was the highest in family support. Emotional support(3.58) was the highest in friends support. Informational support(3.39) was the highest in facilities-concerned personal support. The mean score of hope was 3.41 : the satisfaction with self, others and life was the highest(3.82) and anticipation of future was the lowest(3.27) in sub-scale. There was not a statistically significant relationship between social support and hope. A statistically significant relationship was found between facilities-concerned personal support and hope. In conclusion, facilities-concerned positive encouragement for unwed mothers and a program promoting support and hope from families, friends and unwed father are necessary to promote hope and health in unwed mothers.
