The purpose of this study is to investigate the elementary pre-service teachers' conceptions of 'color of gases' focusing on the survey from freshmen at a National University of Education. For the study, the views about 'color of gases' were surveyed from the pre-service teachers. And the responses were analyzed based on the patterns. The results from the study are as follows: First, the conceptions about 'color of gases' were divided into 2 top-level, 5 mid-level and 7 sub-level categories. Second, the number of students who answered 'certain gas has color' was significantly greater than those who answered 'every gas has no color'. However, only a small number of students who answered former understand the scientific meaning of color and the color of gases correctly. Third, out of 5 misconception categories, greater number of students answered with 'inaccurate scientific knowledge (Ma1)', so the category was classified again into five detailed sub-categories. Fourth, most of the students, who answered 'every gas has no color', stated "they have not seen any color gases through their lives" based on their own experience. Fifth, the distribution percentage for scientific conceptions vs misconceptions was not related with the students' gender but highly related with students' academic area and their science courses taken at high school. Sixth, the pre-service teachers have various types of misconceptions regarding the 'color of gases' and when they have to explain visibility of gases to other people they tend to pass on their misconceptions. Based on the results from the study, some educational guidelines were suggested.

This descriptive study was conducted to ascertain whether the needs of patients with cancer, their caregivers and their nurses changed according to the illness phases and if the perceived needs of the three groups were different for three categories of nursing needs. At two hospitals in Seoul and Choongnam, three groups of subjects, -patients with cancer(79), caregivers(92), and nurses(72) - responded to a questionnaire consisting of items on educational need(11 items), physical need(8 items), emotional need(9 items) using a 4-point Likert scale. The patients and caregivers were selected according to the phase of the cancer (initial, intermediate or recurred, terminal phases). Finding revealed that the level of perception and degree of satisfaction of the needs were low, just around two points in patients and caregivers. Of the three categories of needs, physical needs were received the highest score and the degree of satisfaction of physical needs was also the highest. There was no significant difference between the level of perception and satisfaction of needs in patients and caregivers according to the phases of the illness and the degree of per reception and the satisfaction of the patients were not significantly different and caregivers showed the same result. There was a significant difference in the level of importance of the needs of nurses according to the phases of the cancer. They perceived emotional needs were the most important in first phase and second phase, physical needs in third phase and the educational needs were more important in the first phase than in any other phase. The degree of importance of needs was significantly lower than the degree to which needs were addressed, according to the nurses response. In a comparison of patient and caregiver's perceived degrees of need, and need satisfaction, and nurse's perceived degree of need provision, patient and caregiver scores were lower than the nurses.

The purpose of this study, thesis is to find out the main cause which influences recycling behaviors regarding package wastes. For this purpose, it discusses the difference of recycling behaviors based on socio-demographic factors and lifestyle categories and, it analyzes the relative influencing power of socio-demographic factors and lifestyle on recycling. The results are as follow: First, recycling behaviors on grounds of socio-demographic factors showed considerable difference as regards to age and income. At the income level of 3 Million Won (per month) and the higher the age, recycling behaviors were well established. Second, recycling behaviors based on lifestyle categories demonstrated considerable difference. While the pragmatists and sincere-devoted showed quite positive recycling behaviors, the social activity-oriented and other-directed fashion-pursued did not. Third, the most influential factor on recycling was the parsimony-oriented lifestyles.

The purpose of this study was to examine differences in clothing shopping orientation among female adults according to their level of self-esteem and body cathexis. The subjects included 460 women ranging in age from 20 to 69, living in the Daegu area. The data was analyzed by frequency, factor-analysis, mean calculation, ANOVA and the Duncan-test using the SPSS-package. The overall results are as follows: First, clothing shopping orientation fell into five categories: 'hedonic', 'trend conscious', 'store-patronizing', 'economic', and 'independent' shopping orientation. Second, there were measurable differences in clothing shopping orientation related to one's level of self-esteem. Third, there was a significant difference in clothing shopping orientation according to the one's level of body cathexis. It appears that high levels of body cathexis do predict a tendency towards a more 'independent' clothing shopping orientation.

This paper attempts to identify the term "tectonics" comprehensively by collecting and categorizing existing definitions of tectonics within the architectural area rather than to stress the concept of tectonics of each specific theorist. Although no consensus of opinion on the concept of tectonics exists, architectural tectonics was closely related to the following terms in three categories: 1. $techn\acute{e}$, technique, and technology; 2. construction and structure; and 3. stereotomics. Based on its etymology, system, and material construct, the notion of tectonics common in these three categories signifies "the art of framing construction," in which linear elements are connected with joints and clad or infilled with lightweight material. Thus, the art of framing construction, as a common concept of tectonics, reveals the following characteristics: First, tectonics is based on framing construction in contrast to piling-up construction as the etymology of tectonics signifies the art of carpentry. Then, the term tectonics, dealing as it does with a higher level of construction rather than the mechanical level of structure, incorporates the poetic aspect of techne as well as the rational aspect of technology. Third, Owing to the organic, double system of tectonic frame and incrusting or infilling materials, the tectonic body becomes both the ornament and the structure simultaneously. As the art of framing construction is based on material construction rather than structural or ornamental form, this paper proposes that one can view tectonics as a term that conveys the meaning of the actual material effect on space.

The HKIB, or Hankookilbo, test collections are two archives of Korean newswire stories manually categorized with semi-hierarchical or hierarchical category taxonomies. The base newswire stories were made available by the Hankook Ilbo (The Korea Daily) for research purposes. At first, Chungnam National University and KISTI collaborated to manually tag 40,075 news stories with categories by semi-hierarchical and balanced three-level classification scheme, where each news story has only one level-3 category (single-labeling). We refer to this original data set as HKIB-40075 test collection. And then Yonsei University and KISTI collaborated to select 20,000 newswire stories from the HKIB-40075 test collection, to rearrange the classification scheme to be fully hierarchical but unbalanced, and to assign one or more categories to each news story (multi-labeling). We refer to this modified data set as HKIB-20000 test collection. We benchmark a k-NN categorization algorithm both on HKIB-20000 and on HKIB-40075, illustrating properties of the collections, providing baseline results for future studies, and suggesting new directions for further research on Korean text categorization problem.
