This study was carried out to find out the effect of food hygiene awareness on kitchen employees' performance in the banquet cuisine of five-star hotels in Seoul. 279 kitchen employees were asked to fill out the questionnaire, and the collected data were analyzed by SPSS package(version 11.0). First, results of analysis on food hygiene showed that there were four factors, each respectively named as, food security regulations, food storage, period of circulation of food, and food safekeeping. Second, after analyzing each item in whole according to each of the factors, the average degree of priority on food hygiene in general was 4.52. Results according to each of the elements showed that food security regulations(4.56) and period of circulation of food(4.55) were considered as a priority. After analyzing the difference between the degree of priority and degree of performance according to each of the factors, it was found out that the latter was significantly lower than the former in all factors. Third, after analyzing the difference of food hygiene priority in accordance with general characteristics, statistically significant difference was only shown in education(F=3.308, p<0.05) and class(F=4.418, p<0.01). Fourth, after analyzing the difference of food hygiene performance in accordance with general characteristics, the only significant difference was found in food security regulation of education(F=4.418, p<0.01) and food security regulation of class(F=3.859, p<0.01). Fifth, after analyzing the effect of cook's awareness of priority on food hygiene on the degree of performance, it was found out that the awareness of priority on food hygiene had a positive effect(+) on the degree of performance. Therefore, we can conclude that as kitchen employees recognize the priority on the food hygiene better, their degree of performance was higher.

유한 모집단에서 총계 추정에는 표본의 각 관측값으로 만들어지는 선형 추정량이 사용되는데 이때 사용되는 가중치는 표본 추출 확률의 역수를 사용한 기본 가중치를 모집단 전체에서 얻어지는 보조 정보를 이용하여 보정한 형태로 종종 사용된다. 이렇게 보정된 가중치를 사용한 추정량은 그렇지 않은 추정량보다 효율이 더 좋아질 수 있는 장점이 있으나 이러한 경우 분산 추정은 더 어려워지게 된다. 본 연구에서는 보정된 가중치를 사용한 추정량의 분산 추정을 다룬다. 가중치 보정의 일반적인 형태를 밝히고 이 경우 가중치 보정항은 유한개의 장애 모수(nuisance parameter)의 함수로 나타낼 수 있으므로 이 장애 모수에 대한 테일러 전개를 사용한 분산 추정식을 구한다. 이렇게 구현된 분산 추정식은 기존의 가중치 보정 추정량뿐만 아니라 보다 일반적인 경우에서도 적용될 수 있다는 장점이 있다. 몇가지 응용 사례와 모의 실험 결과를 소개한다.

In this study, the effects of concept mapping with feedbacks providing explanatory comments on students' achievement, science learning anxiety, and science learning motivation were investigated in the undergraduate general chemistry course. The aptitude-treatment interactions between students' level of mastery goal orientation and the concept mapping with explanation feedback treatment were also examined. Sixty-seven freshmen from an university of education were assigned to a control group and a treatment group. The tests of mastery goal orientation, science anxiety, and science learning motivation were administered as pretests. For the treatment group, feedback providing students with explanatory comments through whole class discussion was presented after each concept mapping. Whereas the control group students were presented with opportunities solving excercise problems followed by explanation feedback. The intervention was lasted for 10 weeks (30 class periods). After the instructions, a researcher-made achievement test, the science learning anxiety test, and the science learning motivation test were administered. The results indicated that no statistically significant difference was found in students' achievement. In the science learning anxiety, however, the scores of the treatment group was significantly lower than those of the control group. The scores of the treatment group also tended to be higher, though not significant, than those of the control group in the science learning motivation. However, no significant aptitude-treatment interactions were found in all dependent variables.

This paper seeks to find out the policies of management and layout of middle school rooms for the community people's use. This paper surveys community's needs with respect to both the use of school rooms before, during, and after classes and preferences of use of school rooms. This paper adopts two experimental case studies to find out the models. It uses t-test analysis of the statistics to find out community people's preferences for the use of school rooms between two communities in an urban area, and uses simple and multiple regression analyses to develop models concerning community people's uses of school rooms before, during, and after classes. It also uses cluster analysis to find out the cluster among community people's preference of school rooms. It found, first, that community people's use of school rooms after class can be influenced by the uses of a play ground, a music classroom, an audio visual classroom, and a gymnasium. The use during regular classes is related to the uses of the fine arts classroom, a general classroom, a home economics classroom, a gymnasium, and a playground. The use before class is affected by the uses of a fine arts classroom, a playground, and a library. It also found that, with respect to community people's preferential use of school rooms, the rooms can be clustered as a cluster of laboratories such as a general classroom, a music room, a fine arts classroom, a science classroom, a home economics classroom, and a technique classroom, a cluster of athletic areas such as a gymnasium and a playground, and a cluster of supporting facilities such as a library, an audio visual classroom, and a computer classroom. Those clusters can also be clustered in more detail, i. e., that both a general classroom and playground can be apart from a cluster of laboratories or a cluster of supporting facilities; that an audio visual classroom can be fostered into a cluster with a home economics affairs classroom and a technique classroom. Finally this paper suggests policies of management and layout of school rooms.

In terms of class, race, or gender, critical literacy takes seriously the problem of inequality and injustice embedded in texts. Texts are considered as tools that are used for maintaining the status quo by constructing and communicating our identities, particularly in relation to others. While reading texts and identifying our roles in society, some feel empowered, and others, marginalized. Thus we need to challenge the characterization and the message included in those texts by asking problem-posing questions. In this paper I have demonstrated how to read and teach four versions of "Snow White" from a critical literacy stance. By the use of problem-posing questions, students are led to discover that one of Grimms' fairy tales, the original version of "Snow White," was written from the perspective of men with power, thus marginalizing women in general, as well as the seven dwarfs. Through a critical analysis of Snow White's personality, the typical theme of fairy tales - good is rewarded while evil is punished - should be challenged. In the animation, Snow White and the Seven Dwarfs, power is given to the marginalized people in the original, the seven dwarfs and women in general. In "Snow Night,"a feminist short story, women in general are empowered while men, who should be judged by their looks, are powerless. "Snow-Drop"reminds us of the original, but challenges stereotypes, prejudices, and the theme inherent in the story. In those three stories many parts from the original are rewritten from the perspectives of the marginalized, but still some people are described prejudicially. So students should be guided to write another story from a new perspective. When those four works were taught with problem-posing questions in a university, this approach proved to be quite successful: most students acknowledged the effectiveness of critical literacy in teaching literary works.
