This study examines correlations between affective variables and English learners' achievement in native teachers' classes. Specifically, it aims to study the relationships among Korean college students' English learning motivation, anxiety, WTC (willingness to communicate) and their English achievement scores. For the purpose, the questionnaire surveys were conducted, and the students' English scores were analyzed and compared. The participants were 216 university students taking the general English courses as a requirement for graduation. The results indicated that although the students had high level motivation to learn English, especially for social reasons, their WTC in and outside the classroom was low. Also, unlike the previous studies on foreign language anxiety, their anxiety level was not significant. Anxiety and motivation were negatively correlated; WTC and motivation were positively correlated. However, according to the regression analysis, the explanatory power of the three affective variables was not significant for the students' achievement scores. Several possible reasons and some pedagogical implications are provided in the conclusion.

Even though, many enterprises began to use management information system, they were not able to attain remarkable outcome. Thus, a purpose for this research is to explore effect that characteristics of information technology and executive support have on its user's confrontation In order to verify this purpose, we selected Nong-hyup's CRM as an object for a proof of effect that characteristics of information technology and executive support have on its user's confrontation. According to this research's conclusion, characteristics of information systems have notable influence on user's confrontation, while executive support did not have significant influence on it. Yet, this research has its limits by considering characteristics of information technology and support from board of directors as only variables among many other possible reasons for user's confrontation. Thus, in the future, there should be another research that considers more various reasons for user's confrontation.

The obese population has been increasing over the world wide and obesity became a socioeconomic problems. It is become more serious by the accumulation of the knowledge that the obesity is related directly or indirectly with several diseases like, diabetes, hypertension, etc. With these reasons, many functional food or agents for the purpose of weight loss have been developed. However, most of these remedies are unproven and some have produced even dangerous side effects due to the ephedrine alkaloids contained in Ma-Hang. Because of these reasons, they banned using of these agents in US and regards the antiobesity functional agents as drugs in Europe. Several functional agents are known for weight loss activities like, HCA, L-canitine, CLA, chitosan, calcium supplements and capsaicin containing red pepper, kimchi and kochujang. We describe here about the function, efficacy and mechanism of these antiobesity functional agents. Furthermore, the trial of the mixture of weight loss related herbal ingredients for safe multifunctional antiobesity functional agents are discussed here, as well.

This paper is a study on the shaman's costumes which were observed in the ritual of Jae-Soo-Kut held in Seoul. In this study the forms and functions of the shaman's costumes in Jae-Soo-Kut are compared with those of other Korean traditional costumes and differences are identified between them. The results of this study are also compaed with those of the study on the shaman's costumes in Chun-Sin-ut and other Koean traditional costumes. Shaman's costumes have undergone changes with the decrease in the number of believers in Kut resulting from the diffusion of foreign religion the weakening of believers' faith in Kut resulting from the improvement of science and technology and higher education and the invention of new textiles and development of sewing technology. The reasons why the Kut is performed even nowadays are also discussed. Among those reasons firstly Koreans hold to their own folk religions. Secondly the kut has peculiar artis-tic value for Koreans.

An influence measure known as Cook's distance has been used for judging the influence of each observation on the least squares estimate of the parameter vector. The distance does not reflect the distributional property of the change in the least squares estimator of the regression coefficients due to case deletions: the distribution has a covariance matrix of rank one and thus it has a support set determined by a line in the multidimensional Euclidean space. As a result, the use of Cook's distance may fail to correctly provide information about influential observations, and we study some reasons for the failure. Three illustrative examples will be provided, in which the use of Cook's distance fails to give the right information about influential observations or it provides the right information about the most influential observation. We will seek some reasons for the wrong or right provision of information.
