This study is to find out how well elementary school gardens work as places of observation learning. We compared the tree species planted in elementary school gardens with those which appeared in the science textbooks of the 7th Korean National Curriculum. The number of tree species are 60 throughout all the grades, specifically; 43 in the third grade, 22 in the fifth grade, 16 in the first grade, 15 in the second grade, 8 in the sixth grade, and 5 in the fourth grade, respectively. Their frequency of appearance (hereafter referred to as 'appearance frequency') throughout all the grades is 175, and the maximum frequency is 62 in the third grade. Of particular note is the fact that the appearance frequency in one grade was very high, meaning that a repeat study will not be conducted. The total number of tree species counted in the study was 13,028 and consisted of 167 species in 52 families. Only 23% of the total planted tree species, that is, 38 tree species appeared in the textbooks, so the ratio of the practical usage of school gardens was revealed to be low. In the school gardens, there are only an average of about 16 tree species per school. The fewest number of species in one school was 9 and the most was 22. The native species were 74 and the non-native species were 93. This means that almost all the planted species do not relate to observation learning in the textbooks. The 22 tree species among 60 species in the textbooks were not planted in the gardens. In conclusion, the degree of utilization of almost all the elementary school gardens examined during this investigation was very low.

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 study investigated both elementary and middle school students' abilities of reading scales and students' conceptions of measuring instruments and units. Seventy two students with 5th grade, sixty nine students with 7th grade, and eighty students with 9th grade were participated. Performance tests and written questionnaires were used. To assess their scale reading abilities, individual performance test was used. Every student should measure length of an envelope, temperature of water, volume of water, etc. And to find out students' conceptions related with measuring instruments and units, written questionnaires with pictures and photographs were used. Some of the students' abilities of reading scales were considerably poor. The results of a two-plate-balance and measuring-cylinder were worse than those of a ruler, a spring-balance, and a thermometer. Many of the students had misconceptions related with measuring instruments. Some of them did not know exactly the meaning of volume, or mass, or force. So they did not know what to measure with the measuring instruments. Also students were confused with several units of volume, force, weight and mass.

This study presents the shape creation process using L-system model of morphogenesis technique. In general, L-system model has been applied to represent the visualization of biological plant. But, this study proposes the shape generation process of L-system model to apply the architectural field. The L-system model consists of two parts such as string generation step and string analysis step. The string generation step shows the process for a string rewriting. This step requires alphabet, axiom and rules to generate a string. Also, the string analysis step gives the meaning in string to generate various forms. Especially, through the various application examples, we can find out the shape creation models for the space structures.

The meaning of foodservice industry is various but especially its most important one contains a service industry. And so, foodservice industry should provide very impressive service to customers. if workers don't satisfy themselves at the works, they can not give a high qualifying service to the customers. Therefore, this study showed how the worker's satisfactory degree depending on working type effects on the growth of foodservice industry. The conclusions by questionnaires to workers who have worked as both a regular and a contract employment at Special First Degree Hotels in Seoul are followings. Very interestingly, the proportion of satisfying degree for the workers as regular is 34.94% but the degree for workers as contract is 36.8%. The reason is that the average age of regular workers is high and they have their family to support and they have changed their job more often than the others. They can express their problems through a labor union but the part of solution is very small. It must cause to decrease satisfying degree. The workers generally satisfied to their senior employers. It means that the negative image of higher-ups in the past has been changed. It is a serious problem that the proportion of satisfaction degree remains 30%. The managements must perceive the fact that the increase ratio of contract workers does not make low quality of service. They should know that the satisfaction degree of regular workers is lower than contract ones. In order to increase the satisfaction degree, if the managements can find out the way of taking over their authority and giving a motive, they can reduce the ratio of occupation change and nonattendance. And also they can promote the productivity in foodservice industry and in conclusion, the foodservice industry will have glowed very successfully in the near future.

In this study the features expressed by the Korean dresses and its ornaments have been examined through the objects of this thesis, the concept of the pair, under the basis of Korean myths, from which esthetic and spiritual values have been derived. At first, the beauty of the balance pursuing the neatness. Since the pair is made with two piecess, at the time of the placement, the sense of the balance is obtained by the arrangement acccording to the dichotomous principle such as up and down or left and right. Sometimes, the pair could yield the natural pictorial composition, but almost of the time symmetrical composition. This kind of composition is made symmetrical like the structure of the human body, and it is resulted in a neat beauty, which visually presents a harmony, stability and intimacy. At second, the beauty of the harmony in the spirit of the oneness. From the dualistic combination basing on Korean myths, the common features and the significance of the co-existence, obtained from the combination of the pair of the pieces, could be found. By the oneness of the both elements, the creation principle, which is the basic one for a new life, could be established, and the mystery of the creation and the sense of the harmony could be found in it. At third, the wholeness of the completeness concept. The completeness could be felt rather by two than by one, and is provided with a room to be filled with the other one. Consequently, the outer dress is completed with the under dress, and its own beauty could only be made out when the two elements are harmonized. So, it is called as the pair. Like this, the concept about the pair taken roots in the ground of Korean emotions, is basing on the creation principle of the dualistic elements formed from the tradition of Korean myths, and the fact that the mental meaning pursuing the harmony dwells in Korean dress and its ornaments could be confirmed.

This study summarizes the dissemination aspects of liturgical vestments in Korea, and organizes the value and meanings of these disseminations as it appeared in the history of costumes by carrying out an empirical analysis on the relics of liturgical vestments since the modern times. It also examines its design characteristics as well. Liturgical vestments have symbolic meaning for the purpose and solar term of ceremonial occasions and it also functions as a way to differentiate the position and duty of the clergy. Liturgical vestments developed on the basis of ancient Greek-Roman costumes and transformed each situation and social trend of the age. Korean liturgical vestments started with their traditional costumes, in 1887, it were changed into French(western) style with freedom of religious. After the secondary Vatican Council held in 1962, various regulations were changed to spread the Catholic doctrines and ideology. This study conducted an empirical analysis and design consideration on the 28 relics of modern liturgical vestments on the basis of the foregoing standard and concept. As a result of analysis, relics were investigated as research materials worn by Bishops after 1960s. And design elements are that the relics used materials and ornament of Hanbok with flower patterns and decoration such as letter patterns including 壽(life) 福(luck) 喜(pleasure) as well as Chrysanthemum and Mancaowen design. These transition reflected by amend regulation of Vatican Council II. Accordingly, this data has been confirmed to be important for the history of costumes as it informs what process of changes liturgical vestments spread in Korea went through before they are worn as current appearance.

The purpose of this study is to reinterpret sexuality represented in fashion since the latter half of the 19th century in a contextual view, on the basis of Foucauldian idea of post-structural sexuality. As for research methodology, literary research was undertaken from the conception of sexuality to a historical review of the culture and dress. Foucault maintains the view of plural sexuality, which floats by power relationship between dominant and oppositional discourses in a specific historical context. In contextual approach sexual ideology codified in fashion since the latter 19C shows the following aspects: First, the traditional sexual ideology in the latter 19C is a capitalist value, which gives a priority to bourgeois man's profits, and the Victorian discourses of sexuality constructs the dichotomized fashion of the period. Next, the former half of the $20^{th}$ C is regarded as the period of conformity rather than opposition with various alternatives appropriated to the mainstream, so the traditional sexual ideology in fashion of this period is still preserved. Finally, in post-capitalism period of the latter 20C a variety of anti-fashion visualized plural sexuality from the enormous oppositional discourses. Although it doesn't all mean deconstruction of sexuality in fashion by the anti-fashion re-appropriated without oppositional meanings, pluralization of sexuality implies dynamics of sexual discourses in the next historical period. As a result, fashion since the latter 19C has been changed as a means for expressing age and sexual desire out of gender and class. And mainstream fashion in even postmodern period keeps the modern value on the center of the hegemonic heterosexual masculinity though the increase of Androgynous Femininity in women's fashion may connote the meaning of femininity. The plural sexuality represented in fashion has a contextual flexibility, thus sexuality floats with a specific socio-cultural context and fashion represents a masquerade as an identity vehicle.

The purposes of this study were to analyze the gap between foodservice personnel and inpatients, to urge foodservice providers to reconsider by identifying the problems in service delivery for customer satisfaction, and to deduce the priority for foodservice quality improvement. The results of this study can be summarized as follows : the average perception score of personnel (4.32 out of 5) was higher than that of customers (3.90). In particular, the customers' perceptions of 17 attributes, which included 'removal service of tray by foodservice personnel', 'nutrition and health-related information service', 'handling inpatient's complaint ASAP', 'delicious meals' and 'salty enough meals' and so on, was significantly lower than personnel's. Both service providers and customers perceived that 'personnel attitude' was the highest and 'meal quality' was the lowest among the 4 factors, but there was significant difference on 'meal quality'(p < .001), 'customer reception' (p < .001) and 'personnel attitude' (p < .05) between the two groups. As a results of quadrant analysis, 'removal service of tray by foodservice personnel', 'handling inpatient's complaints ASAP' and 'meal service according to doctor's orders were categorized into Quadrant A with meaning of high personnel's perceptions and low customers'. Therefore service providers have to perceive the gap between the two viewpoints and grant priority to these attributes in improving foodservice qualify.

User interlace comes out from the combination of various school systems. It may be a strong point but could be a weak point, as the characteristics and peculiarity of specific school system cannot be well reflected. Therefore, the study aims to find the oughtness of developing the user interface system on which the characteristics and peculiarity of design area are reflected, and to find the necessary features and viewpoint in development. To make this, this study examines the relationship of human and target, and technical form and meaning of the relationship regarding the user interface, and analyzes the similarity and difference through the design comparison. In addition, this study looks the background for the introduction of user interface in design area and analyzes the cause to study the relationship between the design and user interface. Consequently, the concept and system of the user interface can be included in the broad sense of design, but has not been developed into the appropriate system for the characteristics of design. Therefore, it is necessary to develop the concept, method and knowledge considering the characteristics of design upon concept interpretation and development process.
