CFRP는 경량화 소재로 각광받고 있으며, 해양산업에서도 고급요트와 특수목적 선박 등에 사용되고 있다. 전기추진체계 또한 친환경 추진 방법으로써, 요트와 소형 여객선 등의 주 추진계로 활용되고 있다. 본 연구에서는 소형선박의 선체소재와 추진계를 각각 CFRP와 전동기로 교체하였을 때의 경량화 효과를 정량적으로 비교분석하였다. 45ft GFRP 선박을 대상으로 사례연구를 수행하였으며, 선체소재를 설계원안과 동일 함침율 기준의 CFRP로 재설계하였고, 추진계는 설계원안의 동일 마력, 항해거리를 유지할 수 있도록 전동기와 배터리 시스템을 설계하였다. 연구결과 CFRP 소재는 선각을 45 % 정도 경량화 할 수 있었고, 전기추진체계는 기관부를 58 % 경량화 할 수 있음을 확인하였다. 다만 전기추진체계의 경우, 디젤 추진체계의 항해거리를 확보하기 위하여 상당한 양의 배터리 팩을 필요로 하기 때문에, 현실적인 수준에서의 경량화 실효성은 없는 것으로 확인되었다.

This research was designed to compare clothing fabric images between on- and off-line by fabric types and its characteristics. 125 subjects who have a fashion design major evaluated the fabric image of various 16 kinds of specimens on- and off-line. Frequency, x2-test, t-test, and Pearson correlation were used for statistical analysis by SPSS WIN 11.0. The results of this study are as follows: 1. The advantage of on-line shopping includes low price and purchasing convenience, etc. On-line shoppers mostly purchase clothing items, such as T-shirt and slacks. In most cases, texture of fabrics provides a main cause for the shoppers' discontentment with internet shopping. 2. The results of t-test for the difference of the evaluation score show that plain or pile weave and highly thick or thin fabrics-for example, Organdy, Corduroy, Nylon Taffeta, Plush, etc.-have a large difference between on-and off-line image. On the other hand, medium-thick twill weave-for example, Tweed, Flannel, etc.-or patterned weave-Chiffon, Dobby fabric, etc.-shows a small difference. 3. The results of correlation of the evaluation score indicate that wool twill fabrics like Tweed, Saxony, and Polafleece show a high correlation between two kinds of evaluation score. In texture preference, no correlation exists between on-line and off-line. 4. With an analysis on fabric image evaluation by fabric characteristics, smooth, shiny pink Satin was found the most positively-evaluated item in all evaluation fields except in pattern preference and individuality. On the other hand, thick olive green Corduroy was evaluated most negatively in the fields of elegance, luxury, and feminine. 5. When compared with real ones, thin fabrics provide a different on-line fabric image. For example, Nylon Taffeta and Organdy were evaluated positively on-line because of luster and pastel tone color. However, lusterless uneven cotton Seersucker was evaluated negatively. 6. Real fabrics preference is more negative than on-line ones. In addition, patterned or unique fabrics display a high agreement between the two kinds of images.

This study attempted to identify the characteristics of chair design from furniture company, $K{\ddot{a}}llemo$, the furniture manufacturer in Sweden manufacturing mostly the limited edition of art furniture on the basis of the unique management philosophy. There are 12 artists manufactured chairs for $K{\ddot{a}}llemo$. Of them, this study selected 4 artists-Sigurdur Gustafsson, John Kandell, Komplot Design, Mats Theselius-who designed at least more than three chairs. Total 25 chairs were analyzed; 6 from Sigurdur Gustafsson, 8 from John Kandell, 3 from Komplot Design and 8 from Mats Theselius. The chair structure was divided into three parts, seat, back and structure and analyzed by material, color, type of legs and finishing. The following results were derived from the study. First, $K{\ddot{a}}llemo$ secured the regular customers who want to possess the chairs as the artistic works by continuing the small quantity mass-production system insisting that the maximum quantity of production is 360 pieces and the minimum quantity is 33 pieces. Second, the sufficient time and cost were invested in the initial phase of design. This approach seems to be deviated from the traditional business system that has to create the revenue at a glance, but ultimately induces the commercial success by exponentially increasing the revenue through the creation of various product lines. Third, $K{\ddot{a}}llemo$ provides the space that the artists who work for $K{\ddot{a}}llemo$ can sufficiently enjoy the mental composure and luxury required for the designers by strictly selecting the artists and providing the best environment for enabling the creative activities that look like the pure art area. This study enables the further analysis and research on other collections of $K{\ddot{a}}llemo$ that mass-produces the chairs on the basis of the unique philosophy in the world as well as in Sweden using more various kinds of analysis frameworks.

Many of penthouse apartments began to be built and distributed in Korea from the 2000s. However, we have a transformed definition from the international concept of penthouse. It seems that the penthouse apartments in Korea have a confined definition as a luxury and privileged house-we often find it out from advertisements of newly built apartments. In this thesis, therefore, it needs to make a clear and substantial definition of penthouse. And on the base of this definition, this study is intended to analyze planes of penthouse apartments which are distributed recently. It is in order to find out positive aspects of penthouse apartments and to make practical application of this analysis. The process of this study for plane-planning is as follows. Firstly, it is investigated and analyzed that external factors that have an effect on plane-planning such as locations and types of penthouse apartments. Secondly, an interior of penthouse apartments are divided into a private, public and outward area. And properties of each area through this research show the way of division and arrangement of plane. Thirdly, methods of connection between spaces is analyzed on the base of results of research for the way of partition. Finally, specific characters of penthouse apartments planning is derived from synthesis of research. In conclusion, analysis of plane-planning of penthouse apartments is summarized as follows. The majority of penthouse apartments is arranged to small portions of households and on higher stories in apartment which is situated around Han River or public parks. These external factors influence the plane-planning in both the interior and exterior way. For the exterior planning in space, it becomes important to design bays as many as possible in contact with outside in order to satisfy demands for fine prospects. It is also important to plan extra places naturally such as a terrace in order to provide virtual grounding. In the interior planning, a large size of interior induces to develop space for linking between each area, such as corridors or extra rooms. This makes it possible that the private area is linked to each other, at the same time it has its own distinctiveness according to its usage.

기와라는 건축 재료는 기본적으로 방수와 방습을 목적으로 하며, 중요 건축물에만 사용이 제한되어 권위까지 보여준다. 특히 출토 사례가 드문 삼국시대에는 더욱이 그럴 것이다. 그마저도 신라, 백제 지역의 유적에서 확인된 기와가 대부분이다. 현재까지 가야 지역에서 확인된 기와 중에서 가장 오래된 제작기법을 보이는 부원동 유적 출토 기와 이래로 금관가야 왕궁지로 추정되는 김해 봉황동 유적에서 최근 삼국시대 초기 기와가 출토되었다. 이들은 금관가야의 고도인 김해 지역 초기 기와의 양상을 살펴볼 수 있는 중요한 자료이다. 봉황동 유적 일대에서 출토된 기와는 연질 소성의 세석립이 일부 포함된 적· 황갈색 계통의 색조를 띠며, 두께가 얇다. 내면에는 포목흔이 확인되지 않으며, 점토띠 흔적이 보인다. 내· 외면에 타날흔 및 목리흔이 뚜렷하게 관찰되며, 깎기조정 및 물손질흔과 내면에 내박자흔도 확인된다. 이를 통해 무와통작법의 토기 제작방식과 동일하게 만들어졌음을 알 수 있다. 가야 토기를 제작하던 도공집단의 계통과 연결시켜 본다면, 고령 송림리, 인천 불로동, 경주 손곡동·천리 유적 등과 같이 와도겸업(瓦陶兼業)이 이루어졌을 것으로 추정된다. 현재까지 김해 지역 출토 기와는 김해 분지 일원의 금관가야 도성(왕성)으로 추정되는 범위 내에서만 확인되었으며, 이는 의미하는 바가 크다. 문헌기록과 지금까지의 발굴조사 성과 및 입지적 경관 등을 통해 보았을 때, 봉황동 유적 일대는 금관가야 도성 후보지로 유일하며, 출토된 기와의 존재를 통해서도 이러한 면모를 보여주기 충분하다. 이 시기 기와는 소량 출토되는 점 등으로 미루어 보아, 지붕자재로써의 기능보다는 상징적 의미를 지닌 위세품으로서의 역할이 더욱 컸을 것이며, 사용 범위의 제한 및 통제가 엄격히 이루어졌던 것으로 추정된다.
