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.

This article describes the interview data with two preservice teachers where they dealt with five water-filling problems for the investigation of their covariational thinking. The study's results revealed that two students developed their covariation levels from Direction level to Instantaneous Rate with an aid of the pre-constructed GSP simulations for the problem situations. However, this study also points out that there is a missing important feature for a function notion, 'causality' in the covariation framework and suggests that future research should combine students' conception of causality with their covariational thinking for the investigation of their development of a function concept.

This paper comes to derive optimal decision rule from incomplete information using the concept of indiscernibility relation and approximation space in Rough set. As there may be some errors in case that processing information contains multiple or missing data, the method of removing or minimizing these data is required. Entropy which is used to measure uncertainty or quantity in information processing field is utilized to remove the incomplete information of rough relation database. But this paper does not always deal with the information system which may be contained incomplete information. This paper is proposed object relation entropy and attribute relation entropy using Rough set as information theoretical measures in order to remove the incomplete information which may contain condition attribute and decision attribute of information system.

Many researchers have focused on consumers' clothes purchase behavior, These researches could not reflect the characteristics of the single consumers' clothes purchase behavior. In addition, little has been written on the single consumer. The purposes of this study are to identify the concept and psychologic characteristics of single consumer and investigate the effects of single consumers' psychologic characteristic and susceptibility to interpersonal influence on clothes shopping pursuing value. Also, It was analyzed how single consumer' pursuing values are different based on the type of single motivation. To test research problems, Data were collected by means of a survey questionnaire, which was sent to 300 single in Pusan and Ulsan. In total, 274 were returned and 14 were unusable because of unacceptable levels of missing data. The Results were summarized as follows: First, self-efficacy, informative and normative influence were positively related to utilitarian pursuing value employee satisfaction. Also, self-efficacy, variety seeking, innovativeness and informative influence had a positive effect on hedonic pursuing value. Second, voluntary single and nonvoluntary single group had different perceptions about self-efficacy, variety seeking, innovativeness, informative influence, and hedonic pursuing value.

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.

This paper deals with a single-phase dynamic voltage restorer(DVR) with a quasi Z-source topology. The proposed system based on a single-phase quasi Z-source PWM ac-ac converter which have features such as the input voltage and output voltage are sharing ground, and input current operates in continuous current mode(CCM). For the detection of voltage sag-swell, peak voltage detection method is applied. Also, the circuit principles of the proposed system are described. During the 60% severe voltage sag and 30% voltage swell, the proposed system controls the adding or missing voltage and maintains the rated voltage of sinusoidal waveform at the terminals of the critical loads. Finally, PSIM simulation and experimental results are presented to verify the proposed concept and theoretical analysis.

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.

The WAP 2.0 system is a newly proposed wireless communication system by the WAP Forum for interoperability across Internet environment and the system takes charge of communication between WAP terminals and existing origin Web servers. The purpose of this paper is 1) to construct a WAP 2.0 proxy proposed by the WAP Forum and 2) to improve the WAP Proxy in order to increase communication efficiency between wired and wireless communication objects. The Improved WAP proxy constructed in this study provides links between wired and wireless communication environments using the split-TCP concept. However, unlike the split-TCP connection, The improved WAP proxy maintains TCP's end-to-end semantics and reduces overhead by avoiding operations as much as possible on the upper protocol layer. In addition, The improved WAP proxy supports SACK(Selective Acknowledgement ) option and Timestamp option for speedy re-transmission which leads to reduction of performance degradation. After constructing the improved WAP proxy under Linux environment, experiments have been taken. The experimental results show that, compared with the experiments when a WAP proxy proposed by the WAP Forum is used, both data transmission delay time and data transmission size decrease to show that communication efficiency is increased. In particular, as packet missing ratio Increases, data transmission size decreases, which demonstrates that the improved WAP proxy is very effective for performance improvement in wireless communication environment.
