The purpose of this study is to examine the formal features and discourse functions f quotations in Korean lectures. In this study, quotations with quotation marks and quotations made from shell nouns, as well as quotations with quotation marks '고, 라고' and quotations made from quotation verbs, were included in the category of quotes. For my research, I examined the form of quotes and the discourse functions of 1536 quotes in the lecture discourse of 66,693 words. As a result, indirect quotations were used much more than direct quotes in Korean lectures (80 % : 20 %). Because a lecture is a informational discourse, it is more important to simplify the information and deliver it efficiently based on the content rather than directly quoting it for the purpose of empathy or vividness of events. On the other hand, however, the speakers(lectures) wanted to guarantee the objectivity and originality of the information delivered. For this purpose, the speakers(lectures) used the form of a semi-directional quotation, which is to maintain the original intonation, modality or to use the direct quotation marker '라고' as the direct quotes. In lectures, the speakers use a variety of discourse strategies to effectively manage the hearer's information acceptance, and many quotes were used for this purpose. Quotes were most often used to develop statements efficiently(22.6%). And many quotes were used to ease the burden of hearers accepting new informations and terms(12.8%). In addition, quotes were used to enhance the original informations(17.8%), and the speaker used them as a hedge to express his thoughts or opinions in a roundabout way(11.4%). Finally, quotes were also used to present examples(9.2%) or to indicate verbal forms in supporting materials such as handouts or textbooks(3.1%). These discourse functions reflects the special nature of the lecture discourse.

The purpose of this study was to examine how the vocational high school teachers perceive the direction of the ideal high school vocational education when suggesting mutual contrast positions on the desirable direction of high school vocational education. 1253 teachers from 25 specialization high schools nationwide participated in the survey. Through the review of previous research, we confirmed the axis of new vocationalism, vocationalism, and humanism on the purpose of vocational education. As a result of investigating the perception of vocational high school teachers about the purpose of vocational education, they tended to recognize the purpose of high vocational education toward vocationalism. In other words, rather than acquiring transferable skills, it is important to acquire concrete skills in specific areas, and it is more important to acquire specific skills that can be utilized immediately after graduation rather than coping with the changing job world. Teachers also recognized that it is more important to organize the contents of education according to the needs of industries and companies than to construct education contents for student 's holistic development. There was also a tendency for teachers to recognize that it is important to prepare them for work immediately after graduation rather than preparing them for as wide a career choice as possible. There was a tendency for the male teacher to perceive the purpose of vocational education more pro vocationalism than the female teacher. In addition, professional subject teachers recognized more pro vocationalism than general subject teachers. As a result of the regression analysis, it was found that gender and subject(professional subject vs. general subject) were significant variables related to vocationalism. And suggested that a careful approach is needed in the policy decision making process when considering the limitations of overly vocationally oriented education and the risks of frequent changes in the purpose and direction of high school vocational education.

Statement of problems: Self-etch adhesives exhibit some clinical benefits such as ease of manipulation and reduced technique-sensitivity. Nevertheless, some concern remains regarding the bonding effectiveness of self-etch adhesives to enamel, in particular when so-called 'mild' self-etch adhesives are employed. This study compared the microtensile bond strengths to ground enamel of the two-step self-etch adhesive Clearfil SE Bond (Kuraray) to the three-step etch-and- rinse adhesive Scotchbond Multi-Purpose (3M ESPE) and the one-step self-etch adhesive iBond (Heraeus Kulzer). Purpose: The purpose of this study was to determine the effect of a preceding phosphoric acid conditioning step on the bonding effectiveness of a two-step self-etch adhesive to ground enamel. Material and methods: The two-step self-etch adhesive Clearfil SE Bond non-etch group, Clearfil SE Bond etch group with prior 35% phosphoric acid etching, and the one-step self-etch adhesive iBond group were used as experimental groups. The three-step etch-and-rinse adhesive Scotchbond Multi-Purpose was used as a control group. The facial surfaces of bovine incisors were divided in four equal parts cruciformly, and randomly distributed into each group. The facial surface of each incisor was ground with 800-grit silicon carbide paper. Each adhesive group was applied according to the manufacturer's instructions to ground enamel, after which the surface was built up using Light-Core (Bisco). After storage in distilled water at $37^{\circ}C$ for 1 week, the restored teeth were sectioned into enamel beams approximately 0.8*0.8mm in cross section using a low speed precision diamond saw (TOPMET Metsaw-LS). After storage in distilled water at $37^{\circ}C$ for 1 month, 3 months, microtensile bond strength evaluations were performed using microspecimens. The microtensile bond strength (MPa) was derived by dividing the imposed force (N) at time of fracture by the bond area ($mm^2$). The mode of failure at the interface was determined with a microscope (Microscope-B nocular, Nikon). The data of microtensile bond strength were statistically analyzed using a one-way ANOVA, followed by Least Significant Difference Post Hoc Test at a significance level of 5%. Results: The mean microtensile bond strength after 1 month of storage showed no statistically significant difference between all adhesive groups (P>0.05). After 3 months of storage, adhesion to ground enamel of iBond was not significantly different from Clearfil SE Bond etch (P>>0.05), while Clearfil SE Bond non-etch and Scotchbond Multi-Purpose demonstrated significantly lower bond strengths (P<0.05), with no significant differences between the two adhesives. Conclusion: In this study the microtensile bond strength to ground enamel of two-step self-etch adhesive Clearfil SE Bond was not significantly different from three-step etch-and-rinse adhesive Scotchbond Multi-Purpose, and prior etching with 35% phosphoric acid significantly increased the bonding effectiveness of Clearfil SE Bond to enamel at 3 months.

The purpose of this study is to analyze the factors which have formed gender images in men's fashion since the middle of the 19th century. For this purpose, the images of gender in fashion were analyzed and historical studies about gender images in men's fashion from the middle of the 19th century to the present days were done. Historically images of gender expressed in fashion were masculine image feminine image androgynous image and genderless image. Among those images masculine image and genderless image. Among those image masculine image and androgynous image have been the gender images in men's fashion since the middle of the 19th century. In psychoanalytic view point the factors which have formed the gender images are related with sexual pleasure. Libido for looking narcissism and exhibitionism have produced masculine image and androgynous image in men's fashion, In socioeconomic view point power structure between the sexes have built the gender images in fashion. Masculine image and androgynous image came in to being in men's fashion for the purpose of displaying power or expressing opposition to power structure between the sexes, In aesthetic view point the aesthetic sense of each age about sex have constructed the gender images. Modernism had influence on building masculine image and post-modernism have formed androgynous image in men's fashion.

The purpose of this study was to analyze the relationship between outdoor play environments and child's play behaviors. The data were collected by this study included field measurement survey, and non-participatory observation from 8 child care centers in Seoul. The field measurement survey were conducted from February 20 to March 20, 2005, whereas non-participatory behavior observation were conducted from June 15 to July 10, 2005. The major results showed the following. 1) Most of child care centers were too small, did not use the adequate surfacing to play various activities, and were made of play equipment setting. 2) Child's play behavior focused on functional play activity and construction play activity. 3) The relationship between outdoor play environments and child's play behaviors showed that small outside play environment with monotonous construction of play setting produced functional play behaviors on children. However, in some cases, despite the small and monotonous play area, diverse play behaviors were observed. These playgrounds at least differed from others in that they provided the place where multi purpose play was possible. This finding shows that multi purpose play areas can be an alternative in small playground environment.

In order to solve the current shortage of parking spaces, and redesign the main gate area of the U University, the research investigated some cases of other schools located in Seoul which actively constructed multi-purpose building structures. Those schools are considered to be good samples showing their efforts to fulfill the needs of more parking spaces in their campuses, and to cover with the growing needs of multi-functioned facilities accommodating services of academic affairs, reading room spaces, and amenities. With the investigation, the research finded out the current trends of campus developments from the sample schools, such as underground parking facilities connected with multi-purpose buildings along the main arteries of campuses. Following the trends the research thoroughly examined the present conditions of our school and tried to make some possible alternatives for the facilities. Under the conditions, the research suggested 1)to construct underground parking lots accepting around 1,000 cars under the ivory tower square located in front of University Administration Building, 2)to develop a big-scaled open square at the university main gate, and 3)to build a multi-purpose structure along the main street of the campus, which included administration services, studying spaces, and some commercial facilities.

Purpose: This review aims at introducing 3 modeling approaches classified into 3 categories based on the purpose (estimation or prediction), structure (linear or non-linear) and phase (steady-state or dynamic-state); 1) statistical approaches, 2) kinetic modeling and 3) mechanistic modeling. We hope that this review can be a useful guide in the model-based approach of calcium metabolism as well as illustrates an application of engineering tools in studying biosystems. Background: The meaning of biosystems has been expanded, including agricultural/food system as well as biological systems like genes, cells and metabolisms. This expansion has required a useful tool for assessing the biosystems and modeling has arisen as a method that satisfies the current inquiry. To suit for the flow of the era, examining the system which is a little bit far from the traditional biosystems may be interesting issue, which can enlarge our insights and provide new ideas for prospective biosystem-researches. Herein, calcium metabolic models reviewed as an example of application of modeling approaches into the biosystems. Review: Calcium is an essential nutrient widely involved in animal and human metabolism including bone mineralization and signaling pathways. For this reason, the calcium metabolic system has been studied in various research fields of academia and industries. To study calcium metabolism, model-based system analyses have been utilized according to the purpose, subject characteristics, metabolic sites of interest, and experimental design. Either individual metabolic pathways or a whole homeostasis has been modeled in a number of studies.
