Fetishism, which has been a taboo for a long time, is stimulating the modem people's emotions by being reborn as a fashion trend by a number of designers like Jean Paul Gaultier, Vivienne Westwood and Claud Montana. Especially, Jean Paul Gaultier, called the bad boy of the fashion industry, is leading the Paris fashion world by expressing his unique fetish elements with his fantastic and uncommon ideas-males' wearing of skirts, wearing underwear like outer garments. Therefore, this study is aimed at investigating how his fetishism is shown in his works, understanding his fetish fashion world in the modem fashion and offering a new stepping-stone for fashion designers to actively participate in new fashion areas. Its results are as follows. First, it was found that the sensual designer Jean Paul Gaultier has been expressing his unique fetish elements in his collections like the following three styles of fetishism-fetishism by physical emphases, fetishism by items, fetishism by material. Second, the symbols of voluptuous beauty reflecting his own fetishism could be found in his movie costumes, license areas and given plots. Third, the work describing Jean Paul Gaultier's fetishism as a fetish image with the concept of Fantasy of Missing was evaluated as a successful work to express an internal sexual desire.

Creative problem solving has become an important issue in many fields. Among problems, dilemma need creative solutions. New creative and innovative problem solving strategies are required to handle the contradiction relations of the dilemma problems because most creative and innovative cases solved contradictions inherent in the dilemmas. Among various kinds of problem solving theories, TRIZ provides the concept of physical contradiction as a common problem solving principle in inventions and patents. In TRIZ, 4 separation principles solve the physical contradictions of given problems. The 4 separation principles are separation in time, separation in space, separation within a whole and its parts, and separation upon conditions. Despite this attention, an accurate definitions of the separation principles of TRIZ is missing from the literature. Thus, there have been several different interpretations about the separation principles of TRIZ. The different interpretations make problems more ambiguous to solve when the problem solvers apply the 4 separation principles. This research aims to fill the gap in several ways. First, this paper classify the types of contradiction relations and the contradiction solving dimensions based on the Butterfly model for contradiction solving. Second, this paper compares and analyzes each contradiction relation type with the Butterfly diagram. The contributions of this paper lies in reducing the problem space by recognizing the structures and the types of contradiction problems exactly.

본 연구는 예비교사들이 어떻게 공변추론(covariational reasoning)의 개념을 이해하는지를 정성연구방법을 통하여 연구하였다. Geometer's Sketchpad를 이용해 만들어진, 문제상황들을 위한 모의실험을 통해 두 학생들은 공변 추론의 단계가 '방향'수준에서 '순간비율' 수준으로 발전하였음이 연구분석 결과로 나타났다. 하지만, 이 연구를 통해 함수 학습을 위한 중요한 개념 중 하나인 '인과성'이 공변추론 양식틀에서 빠져있음을 알 수 있었고, 따라서 앞으로 학생들의 함수개념 발달의 연구를 위해서 공변추론과 인과성이 서로 연계되어 이루어 져야 할 필요성이 제시되었다.

Poor children are a field of causing of various Issues and become a subject of sympathy, concern and anger, against adult's poor such as sleeper outdoors and unemployed to be made a subject of discussion. This study has theoretically investigated the poverty concept, family trait around poor children. And also for understanding the above status, poverty circumstances have been focused children family and shelter-care children. The conclusions are as follows. First, the family of children head was formed with children under fifteen years of age. It was reported that solo families were 26.4% and living together families with relatives were 64.7%. As status of producing causes, parents death was shown the most rate as 49% and abscondence or missing was 31.9%. Second, In the shelter-care aspect, the highest case is a parents-divorce with 42.5%, while children-head case is just shown 0.5%. Therefore, in a child right viewpoint, it needs more systematical/long-range study on children poverty, and some policies for protecting the poverty-children must be established in social policy.

Statement of problem : Since the concept of osseointegrated dental implant by $Br{\aa}nemark$ et al was first applied to mandibular full edentulous patients. Recently it is considerated the first treatment option on missing teeth. A common problem associated with dental implant restorations is loosening of screws that retain the prosthesis to the abutment and the abutment to the implant fixture. Purpose : This study is to examine the influence on screw loosening of implant-abutment designs. Material and methods : External hex, cone screw, beveled hex, cam cylinder, cylinder hex by means of evaluating the loosening torques, with respect to a range of tightening torques after repeated loading. Result : 1. Cone screw, beveled hex groups are the highest initial tightening rate and cylinder hex, external hex groups are the lowest initial tightening rate (p < 0.05). 2. Cone screw groups are the highest after repeated loading tightening rate and cylinder hex groups are lowest after repeated loading tightening rate(p < 0.05). 3. Cone screw groups have the highest initial stability and anal stability. 4. All groups are decreased tightening rate after repeated loading.

Purpose: This study systematically examined the concept of digital selling readiness of salespeople. Additionally, this study empirically confirms the sequential mediating roles of digital literacy and salesperson self-efficacy in the impact of digital selling readiness on customer-oriented behavior. Research design, data, and methodology: We collected data from salespeople at a Bank and Financial Service firm in South Korea. A total of 254 salespeople were invited to participate, with 154 surveys returned. After removing the questionnaires with missing values, 150 complete surveys were employed for the analysis. Results: The empirical analysis indicates that digital selling readiness positively affects digital literacy. Digital literacy, in turn, is positively associated with self-efficacy, leading to increased customer-oriented behaviors among salespersons. This study also confirms the sequential mediating effects of digital literacy and self-efficacy in the impact of salespeople's digital selling readiness on customer-oriented behavior. Conclusions: Our research deepens the understanding of how digital selling readiness fosters customer-oriented behavior through the sequential mediating effects of digital literacy and self-efficacy. This study extends the previous model by sequentially involving digital literacy and self-efficacy to better understand the psychological processes of digital selling. The results highlight the role of digital selling readiness in preparing salespeople for digital sales.

WAP 2.0 시스템은 인터넷 환경과의 호환성을 고려하여 WAP 포럼에서 새롭게 제안된 무선통신 시스템으로서, WAhP 단말기와 기존 Origin 웹서버 간의 통신을 담당한다. 본 연구의 목적은 1) WAP 포럼에서 제안된 WAP 2.0 프록시를 구축하고 2) 이를 개선하여 유무선 통신 간의 전송 효율을 향상시키는데 있다. 본 연구에서 구축한 개선된 WAP 프록시는 split-TCP 개념을 사용하여 유무선 통신환경을 연결하고 있지만, split-TCP 연결과는 달리, TCP의 end-to-end 의미(semantics)를 유지시키고 상위 프로토클 계층에서의 처리를 되도록 줄여서 오버헤드를 감소시킨다. 또한, SACK(Selective Acknowledgement) 옵션 및 Timestamp 옵션을 지원하여 빠른 재전송을 가능하게 함으로써, 무선통신 경로에서의 TCP의 성능 저하를 줄인다. 본 논문에서 구축한 개선된 WAP 프록시를 Linux 환경에서 구현한 후 성능을 측정한 결과, WAP 포럼에서 제안된 WAP 프록시에 비하여 데이터 전송지연시간과 데이터 전송량이 모두 줄어드는 전송 효율의 향상을 얻었다 특히, 패킷 유실율(packet missing ratio)이 클수록, 데이터 전송량의 감소 효과가 점점 커짐을 알 수 있으며, 이것은 개선된 WAP 프록시로 인한 무선통신 환경에서의 성능 항상 효과가 뚜렷함을 입증한다고 생각된다.
