  • The purpose of this study is to examine the concept of Greenhouse Effect as understood by middle school high school university students using a closed-form questionnaire. Based on results of the questionnaire which was administered to 619, the extent to which alternative concepts were held was quantified and compared the difference of various group based on grade level. gender, text and major. Also, subjects were divided into two groups, one is middle school students and the other is high school university students and common themes within conceptual framework of each group were identified by factor analysis. The result showed that students confused Greenhouse Effect with ozone layer depletion in stratosphere and linked familiar contamination around everyday life. acid rain. radioactive contamination, nuclear arsenal to Greenhouse Effect. These trends were more appreciable in female than male, biology major than any other major and text did not make any significant difference. In addition, the result of factor analysis showed that two groups linked familiar contamination around everyday life to Greenhouse Effect and high school university students understand the consequences of an increase in the Greenhouse Effect more systematically than middle school student, perceived the relation between the origin of an increase in the Greenhouse Effect and human activity but confused Greenhouse Effect with ozone layer depletion in stratosphere.

  • The purpose of this dissertation is to interpret fashion through a socio-cultural phenomenon called kitsch by understanding its aesthetic characteristics and clarifying its significance in the modern consumer society and analyzing the examples of kitsch appearing in modern fashion. The following are the arguments and conclusion of this dissertation. First kitsch has negative meanings such as aesthetic inadequacy or bad tastes implying vulgar popular tastes of faked sensations just imitating elite culture and using things indiscriminately for inferior reproduction or at best the philosophical and aesthetic category that expresses the mass of people's attitudes toward life in accepting the consumer culture of the industrial society. It started from the art of romanticism accompanied by th commercializing of art with the bourgeois society background formed in the mid-19th century. Though kitsch started to prevail following the socio-cultural changes caused by the Industrial Revolution in the 19th century it is only in the late 20th century that kitsch has come tc our everyday life and has become an object of aesthetic arguments. Second formative characteristics of kitsch appearin in fashion have a cumulative inadequate romantic pleasure-seeking satirizing and multicomplex nature. Third the socio-cultural meanings of kitsch appearing in fashion are as follows: The extension of commercialism which gratifies the pleasure-seeking mass consumers the enlargement of the aesthetic category by inclining to everyday commonplace aesthetic sense the expression of one's identity through the gratification of desire and the new aesthetics of resistance and deviance by an anti-traditional and anti-elite tendency towards the traditional society and aesthetic values.

  • The importance of pedagogical content knowledge(PCK) has been recognized in learning science teaching. PCK is based partly on the essence of subject matter knowledges. Therefore, the effective teaching of science content knowledges is fundamental in preservice education of student teachers. But, particularly the science curriculum of primary teachers' colleges is composed of less lessons than needed. This research was executed to identify the content and context of earth science which were contained in questions by student teachers These questions which were written by the students about the earth science content in elementary science texts and teachers' guide books were collected and analyzed. Frequency and context concentration of questions about the themes of contents were obtained. In each unit of the text books, scatter diagrams of question frequency and context concentration of themes showed various features. The main results were as follows. first, in case of the units which contents ate composed of themes expected to be experienced in everyday life, the question frequency and context concentration showed positive correlation between them. But, other units, which everyday life experiences are not expected to influence, did not show distinct correlation.

  • The purpose of this study is to examine the principles of clothing design and the way of design approach in Lamanova. She caused a revolution in the art of dress and created the foundation for costume design theory. She Addressed Art in everyday life to self-taught dressmakers. The distinguishing feature of the design is simplicity and functionality. In an article "The Russian Style", Lamanova raised the question of the new Soviet costume and traditional costume. In "On Contemporary Costume" she classified the new forms of clothes into everyday and holiday attire, showed the principles of costume, and analyzed in detail the necessity of constructing a costume to suit the individual figure. In "On the Rationality of Costume", she found a basis theory for clothing design which is for whom, from what, and for what purpose. Lamanova's theory was made public in full in 1928 and was presented at the exhibition of Handmade Textiles and Embroidery in Women's Contemporary Costume. The main contents are the costume's purpose, it's material, the figure of its wearer, and its form. She argued that the new costume could be in line with the new life and her theory could be the creed of clothing designers. The principles of Lamanova's theory can still be applied today, not only in Russian traditional and contemporary costume, but in contemporary world fashion.

  • The purpose of this study is to develop learning materials for functional concept on variable and to verify the effect of how well students could learn functional concept after they studied with those materials. To accomplish the purpose of this study, I developed learning materials and after teaching students with them. I have concluded the followings : First, there was little effect in teaching functional concept on variable between two experimental groups, whereas teaching functional concept had greater effect on forming functional concept in high level groups in those two experimental groups. Second, teaching functional concept on variable had little effect on students' understanding of functional concept and perfecting tables in Black box, graph, and mathematical problems, whereas there was much effect in students' understanding functional concept and solving relation formula, image, and range problems related to everyday life or general things. On the basis of the problems which appeared in the process of this study, the following can be suggested : First, we should develop learning materials fit for low level students so that they could understand functional concept. Second, we should continue to teach the basic problems like solving relation formula, image, and range, and understanding functional concept in graph until students are able to understand them exactly. Third, since the goals of Unit Function in a middle school textbook is to solve problems related to everyday life through functional thinking, there should be change in constructing systematic contents of Unit Function in a middle school textbook.

  • The study examines how stressful life experiences and negative affective conditions influence refugees' information seeking and uses. Fifty-five North Korean refugees living in South Korea were invited to participate in a survey to determine their level of PTSD and to investigate the relationship between activeness in information-seeking and their negative affect. Seven subjects with severe PTSD symptoms participated in an in-depth interview to describe their information practices in daily life contexts. The study found that participants with higher levels of PTSD tended to seek information more passively than those with lower levels of PTSD. Almost all refugees were unable to recognize their information needs clearly but some subjects stated latent socio-affective needs and financial needs. Most refugees avoided seeking information and learned information through interpersonal sources-staffs in the Hana Refugee Center and volunteers in local community churches-and mass media. Some unique social phenomena were discovered in North Korean refugees' information world and the emergent features were discussed. On the basis of the findings, some practical approaches for improving refugees' information world were also suggested.

  • This study identifies the spectrum of different forms of sharing labor in farm houses following the increase in the production of organic produce and deals with the gender division of labor and every day life of the farm households. The increased labor burdens of organic farming give more work opportunities to wives, weakening the gender barriers. However, some of the farm households seeking for economic feasibility are strengthening the gender barriers by specialized work divisions, leading to outside order labor of harvest, sorting, and packaging in order to increase efficiency in agricultural management in extreme cases. Even in the alternative distribution system, farm households has become subject to the distribution system as it is shown that coop claimed the segmentation of sorting work. This is because the convenience of the customers goes before the advantages of producers. Jinju, seeking for economic feasibility, has established the springboard for growth by greenhouse through monoculture and specialization and are operating economic growth stably. Farm couples with this condition, where their incomes are relatively high, are attempting to recharge their energy during low seasons. It is expected that this will be a model case of conventionalization of organic farming. Significance of organic farming in this matter is discussed.
