Costume is mirror of diverse life styles and attitudes in human life. It has a meaning beyond "clothing" . Fashion illlustration is to express these costumes with a picture. So, it can be said that it is a ′mirror of costumes′ in historical side. The purpose of this study is to find the meaning of fashion illustration of 17th century, which called its first one and to look into its characteristics and costumes of 17th century respotlighting fashion illustrators and painters related with fashion illustration in those days. This study is based on Western Europe by literatures. The fashion illustration in 17th century designed by painters and fashion illustrators. They are Wenceslaus Hollar, Abraham Bosse, Jacques Callot, Jean de st Jean, N. Bonar, A. Trouvain, A. Arnoult in France and so on. The characteristics of fashion illustration in 17th century are as follows : 1. There was a quickening of modern civil consciousness in 17th century. As the subject of costume culture moved from noble class to the working class which began to have a free, the fashion illustration changed to the direction of informing their social class and job. 2. The fashion illustrations of 17th century showed storng realism which was a base of modern picture. 3. The most of them showed costume plates. It was not to transmit adding intended forecast but to describe sincerely in costumes′ record. However, the fashion illustration since the middle of 17th century was designed considering fashion. 4. It could be said that the fashion illustration of 17th century was the forest one of today. It was expressed by Wenceslaus Hollar′s ones. And it is found in his suggestion of popular costumes before and behind and delicate description like accessories. 5. They were transmitted by fashion magazines internationally. Le Mercure Galant, which printed mode plates in 1678, was the first modern fashion magazine aiming at general readers. The fashion illustration of 17th century can divide into ones for court, for working classes, costume plates. The fashion illustrations for court designed by court painters. There were court costumes of early time, spanish Mode and of lately time, French Court Culture. They had baroque elements with a bunddle of ribbons and race decoration. On the other hand, the fashion iooustrations for working class were under the influence on Netherlands styles. They were designed for the purpose of god function and much use. That′s why was under the influence of puritanical life creed. In this situation, the costume plates directed the fashion in those days. At that time, they were supplied widely and it amy be an attempt of popularization. The fashion illustrations of 17th century appeared that they had transmissible character and artistics expression. On the basis of them, we can look into the fashion illustrations of today.

The study presents preliminary research on how science activities focusing on problem recognition worked and affected students' perception of their learning environment in a sixth science classroom. The science activities were based on the Science Writing Heuristic (SWH) which was suggested by Keys, Hand, Prain & Collins (1999), where problem recognition was an important part of scientific inquiry. For developing the working sheets for the modified SWH in this study, analyses of target units of 6th grade science curriculum in the aspects of problem recognition were conducted. After consecutive 6 classes with the developed working sheets for sixth graders, the student working sheets for each lesson were collected and analyzed. In order to investigate the developed units' affect on student learning, students' perceptions of their learning environment were administered before and after the applied classes. Students working sheets and questionnaires on their perceptions of learning environment indicated that students perceived that the science activities were more student-centered classes where students had active discussion and dialogue with one another giving them more chances to actively take part in the class as well as they used more properly recognized their inquiry problem.

In order to investigate if the employment of housewives may affect the nutritional status of their family members, an analysis was made for the data of 2001 Korea National Health and Nutrition survey. Housewives aged 20 or over were divided into two groups of the working (W, 44.3%) and the non-working (NW, 55.7%), and household income levels were divided into 4 groups of low, middle, high, and high above according to the minimum cost of living in the year of 2001. Nutrient intakes were assessed by using dietary recommended intakes for Koreans of 2005. Working housewives showed similar levels to those of non-working housewives in most nutrients intakes except energy and vitamin C. However their families excluding housewives of W, than those of NW, took less protein, calcium, iron, potassium, vitamin A, thiamin, riboflavin, niacin, and vitamin C when assessed as % of recommended intakes and took more sodium. Such differences were very strong in children and adolescents, and in the middle income households. More % of the families of W than those of NW consumed nutrients below the estimated average requirements. Percents of hypertension classified by both systolic and diastolic blood pressure were higher in adult family members of W than in those of NW. This tendency seemed to be more significant in the family members aged 30 to 49. Both obesity and under-weight rates of school children ($7{\sim}12\;yrs$) in W were higher than those in NW. The above resuIts suggested that employment of housewives could have negative influences on the nutritional status of their family members, especially of their children and in the middle income class.

The purpose of this study was to evaluate the size of the temporomandibular joint space by the increase of the occlusal force on the working side and the non-working side during unilateral biting. For the study, 22 normal adults, age from 23 to 25, who had normal or class I molar relationship and had no symptoms on TMJ area and masticatory muscles were selected. Transcranial TMJ radiograph was taken during unilateral biting with the sensor of occlusal load measuring device (MPM-3000 ; Nihon Kohden Kogyo Co. Ltd., Japan) on 1st molar teeth of right and left side given to force of 0kg, 10kg, 20kg and 30kg respectively with Accurad-200(Denar Corperation's product). The radiographs were traced on the screen, with enlaged as 5 times. The size of temporomandibular joint space at anterior, superior and posterior compartment were measured with Dumas's method (reference line between squamotympanic fissure and the lowest point of articular eminence). The following results were obtained by this study. 1. The size of anterior TMJ space showed a tendency to decrease on the working side and increase on the non-working side by the increase of the occlusal force, but had no statistical significancy (P>0.05). 2. The size of superior TMJ space showed a tendency to increase on the working side and decrease on the non-working side by the increase of the occlusal force (P<0.05). 3. The size of posterior TMJ space showed a tendency to decrease on both working and nonworking side, but had no statistical significancy (P>0.05)

본 연구의 목적은 한국 사회에서 '왜, 그리고 어떻게 부모의 학력과 직업지위라는 비경제적 자원이 자녀의 교육성취로 전환되어 나타나는지' 를 밝히는 것이다. 본 연구는 사례연구 방법을 사용하여, 부모의 교육수준과 직업지위가 높은 중산층 가정과 상대적으로 낮은 노동자 및 저소득층 가정으로 나누고, 다시 각 집단에서 높은 학업성취를 이루어 명문대에 입학한 사례와 학업성취도가 낮았던 사례를 분류하여 총 29개의 사례를 비교·분석하였다. 사례를 분석한 결과, 고학력 중산층과, 저학력 노동자 및 저소득층 사이에는 교육에 관한 가치관과 교육열망, 자녀를 공부시키는 방식 및 양육관행 등에서 차이가 발견되었다. 사회계층에 따라 교육열망과 양육관행에 차이가 나타나는 것은 일차적으로, 그들이 사회구조 속에서 겪은 생애경험이 다르기 때문이다. 본 연구는 면접 자료를 분석하는 과정에서, 학력수준이 다른 사회계층 사이에는 학력자본의 가치를 몸으로 느끼는 정도가 사회통념과 다를 것이라는 가설을 구성하였고, 이를 학력 가치 체감(體感)의 역설이라 이름 붙여 하나의 가설로서 제기하였다.

The purpose of this thesis is that the students understand the sentence stated math problems closely related to the real life and adapted the right solving strategies try to find the solution to a problem. The following research problem were proposed. 1. How repeated thinking lessons develop the understanding of problems and influence the usage of correct problem solving strategies and extensions of problem solving. 2. There are how much differences of achievement for each type of sentence stated problems by using comparative analysis of upper class, intermediate class, and lower class for each level between the experimental and comparative classes. In order to conduct this research the classes were divided into three different level - upper class, intermediate class and lower class. Each level include an experimental class and a comparative class. The two classes (experimental class and comparative class) of the same level were tested on the basis of class division record with the experimental class repeated learning papers for two weeks were used to guide the fixed thinking algorism for each sentence stated math problems. Eight common problems were chosen from a variety of textbooks : number calculation problems, velocity-distance-time problems, the density of a mixture, benefit problems, distribution problems, problems about working, ratio problems, the length of a figure problems. After conducting this research experiment The differences in achievement level between the experimental class and comparative class, were compared and analyzed through achievement tests made from the achievement test papers with seven problems, which were worth seventy points (total score). The conclusions of this thesis are as follows: Firstly, leaning activities through the usage of repeated learning papers for each level class produce an even development of achievement level especially in the case of the upper class learners, they have particular differences (between experimental class and comparative class) compared to the intermediate level and lower classes. Secondly, according to the analysis about achievement development each problems, learners easily accept the strategies of solution through the formula setting up to the problem of velocity -distance-time, and to the density of the mixture they adapted the picture drawing strategies interestingly, However each situation requires a variety of appropriate solution strategies. Teachers will have to employ other interesting solution strategies which relate to real life.

Creativity is one of the most popular keyword used in today's society due to it's important role as the major post modern economic drive force. Richard Florida calls the group of people who work in this creative industry as the 'Creative Class' and this theory has affected many organizations and cities. However, little is known about the work environment of this class, so many designers find it difficult to understand how they may encourage creativity in the actual physical setting. Therefore the purpose of this research is to understand the major characteristics of this 'Creative Class' and their working styles in order to develop a theoretical framework for the creative work environment and present a case study of NHN Company main office building. The researcher has indicated three major characteristics of the creative work environment such as 'Individuality', 'Socialization', and 'Experiential' and through the developed framework found that in NHN building 'Socialization' through overlapping territories and programs, spatial openness were used as key methods of encouraging creativity. It is hoped that this research may be used as a useful guide in designing various types of creative work environment for the future.

As the safety fields are expanding to a variety of industrial fields, safety technology has been developed by convergence between industrial safety fields such as mechanics, ergonomics, electronics, chemistry, construction, and information science. As the technology convergence is facilitating recently advanced safety technology, it is important to explore the trends of safety technology for understanding which industrial technologies have been integrated thus far. For studying the trends of technology, the patent is considered one of the useful sources that has provided the ample information of new technology. The patent has been also used to identify the patterns of technology convergence through various quantitative methods. In this respect, this study aims to identify the convergence patterns and fields of safety technology using association rule mining(ARM)-based patent co-classification(co-class) analysis. The patent co-class data is especially useful for constructing convergence network between technological fields. Through linkages between technological fields, the core and hub classes of convergence network are explored to provide insight into the fields of safety technology. As the representative method for analyzing patent co-class network, the ARM is used to find the likelihood of co-occurrence of patent classes and the ARM network is presented to visualize the convergence network of safety technology. As a result, we find three major convergence fields of safety technology: working safety, medical safety, and vehicle safety.
