In this study, I analyzed determinant factors of mutual fund return. The samples was distributed into three types according to the ratio of included stocks in funds. The proxies of mutual funds were set up three ways(returns of fund). As a result of the analysis, I found that growth positively affect to fund return, abnormal return and adjusted abnormal return in all samples. While, according to three types of sample, expected and unexpected fund cash flows had differently effect on fund return. Inferentially, it seemed that the ratio of included stocks in fund was the cause of that. But price pressure hypothesis are not supported. In conclusion, it was not found the possibility of stock market disturbance in this analysis.

This study was conducted from 10 February 2011 until 2 March 2011 targeting culinary workers in deluxe hotels in Seoul. The data from 161 copies of questionnaire were analyzed using SPSS 17.0 for the factor analysis and the reliability test, and the multiple regression analysis was performed to verify the hypotheses. The results are as follows. First, correlation among interpersonal attachment, job satisfaction and job attachment showed that stable attachment had a significantly positive(+) effect on job satisfaction and job attachment. Second, unstable attachment had a negative effect on job satisfaction. Moreover, there were no correlations between job satisfaction and job attachment by the types of attachment. Third, for the effect of interpersonal attachment on job satisfaction, the stable one had a significantly positive(+) effect on job satisfaction; however, avoidant and unstable ones didn't have a significant effect on job satisfaction. Consequently, the results of this analysis suggest the future direction of culinary workers.

Because services are delivered through the behaviors of people, it is very difficult to do the quality control and services failures are often happened. If services failures are not recovered by appropriate methods, customers make the negative word-of-mouth communications and have the negative intention to repurchase. The service recovery paradox demonstrates the importance of service recovery after the service failures. The purpose of this study is to investigate the antecedents of customer satisfaction of service recovery(CS), and its consequences of the CS. Independent variables of CS are distributive justice, procedural justice, and interactional justice, and dependent variables of CS are negative word of mouth communication and intention to repurchase. Data are collected using the scenario method. Research model and hypotheses are tested empirically using the statistical packages such as SPSS and AMOS.

The present paper studies the development of null anaphor,with special attention to whether Korean children's use of null anaphora exhibits the type of directionality preforence predicted by Lust & Mangione(1983)and Lust(1986).If these researchers are correct,anaphora in Korean children's language should be constrained backward since Korean is a left-branching language.That is,it is predicted that Korean chidren would perfer backward anaphora to the forward pattern.For the purpose of this study, ninety-six children were individually tested in an elicited imitation task, twenty-four children from four age groups(4:1-9:7).Three types of constructions,sentences involving a redundant NP,forward patterns of ananphora,and backsward patterns of anaphora were devised.It was discovered that like English speaking children, Korean children prefer forward patterns of anaphora to backward structures.It was thus speculated that the forward preference may well be indedpendent of grammatical factors,reflecting instead processing considerations which favour mention of the referent befor the use of anaphoric elements.

This paper examined the influence of employees' social regard toward the customers, such as, overall service quality, service satisfaction, and service loyalty. The paper proves that the high contact beauty services and the low contact fast-food services have different customer satisfaction level depending on the employees' social regards. A survey study was conducted to collect the data with the actual service purchasers at domestic beauty services and fast-food services. Analysis of structural equation modeling with Amos 18.0 was performed to test the research hypothesis. The results of the study are as follows: First, social regard has positive influences on service quality, service satisfaction, and service loyalty. Second, Social regard has more effect on service satisfaction in a high contact beauty services than in a low contact fast-food services. This paper contribute to identify the effects of employees' social regard on service satisfaction, by comparing the effects on service satisfaction between high and low contact services.

Whereas traditional user interface are well accepted modes of information exchange, the new digital conversion type's of information media is relatively complex and provides new means of transaction with user interface. User interface can be decomposed into two component: the physical structure through which information media is controlled, and the presentation of the content. This research explores the two user interface element have different effect on the adoption of information media and, as such, can influence perceived usefulness, perceived easy of use, and intention of use. The hypotheses have been tested with the survey of 148 end-users examines two interface characteristics factors such as efficiency, error, design, entertainment, accuracy, and vividness, and so on. The research summarized in this paper decomposes the influence of interface elements of physical structure interface and content presentation interface to gain a better understanding of how interface stimulates user's perceived usefulness to adopt the information media.

The purpose of this study is to investigate the effects of informational diversity-sensitive orientation on employee attitudes, focusing on the moderating effects of communication. Recently, diversity within organizations has intensified and the importance of diversity management within organizations is increasing. Diversity studies have focused on the variance of objective diversity characteristics, and have provided mixed results. In order to overcome limitations in the research, this study focuses on members' perception of diversity. To this end, the variable of informational diversity-sensitive orientation(IDSO) was used. Sample data is derived from 301 surveys of employees in firms located in South Korea. Results show that informational diversity-sensitive orientation(IDSO) had a positive effect on job satisfaction and organizational commitment. Regarding the moderating effect of communication, a positive moderating effect was exhibited only in co-worker communication, and differential influence derived from communication type. Based on the analysis results, we discuss research implications and directions for future research.

In spite that the main contents of mathematical and scientific learning are understanding principles and their applications, most of existing educational softwares are based on rote learning, thus resulting in limited educational effects. In the artificial intelligence research, some progress has been made in developing automatic tutors based on proving and simulation, by adapting the techniques of knowledge representation, search and inference to the design of tutors. However, these tutors still fall short of being practical and the turor, even a prototype model, for learning problem solving is yet to come out. The geometry problem-solving tutor proposed by this research involves dynamic inference performed in parallel with learning. As an ontology for composing the problem space within a real-time setting, we have employed the notions of propositions, hypotheses and operators. Then we investigated the mechanism of interactive learning of problem solving in which the main target of inference involves the generation and the test of these components. Major accomplishment from this research is a practical model of a problem tutor embedded with a series of inference techniques for algebraic manipulation, which is indispensable in geometry problem solving but overlooked by previous research. The proposed model is expected to be applicable to the design of problem tutors in other scientific areas such as physics and electric circuitry.

The statistical analyzing of environmental-friendly planning elements is getting important because it is getting concerned with the change of residential types and environmental friendly housing. However, in terms of the high-rise residential complex, paper about green building rating system and research about residential satisfaction to residents are lack. Therefore, this paper is analyzing of impotentness and satisfaction about housing subdivision, inside of building, facility, and maintenance. In addition, residential satisfaction(satisfaction, loyalty, preference) and impact relationship of environmental-friendly planning elements are analyzed by PLS structural equation. To sum up, first, improving of green building rating system in housing subdivision is impacted on loyalty if satisfaction was fulfilled. Second, increasing of environmental-friendly planning elements in inside of building is impacted on loyalty if both satisfaction and preference were fulfilled. Third, providing of green building rating system in facility and maintenance is analyzed as preference, but satisfaction hypotheses is not valued.
