무선망에서 통신 경로상의 노드들은 데이터 전달 시마다 전자기적 신호를 방출하므로 일련의 발생 신호들을 포착하여 분석하면 해당 경로가 노출 및 탐지될 수 있다. 악의적 도청자에 대응하는 방법의 하나로는 특정 노드들로 하여금 더미(거짓) 패킷을 생성하도록 하여 마치 데이터 경로상의 노드들처럼 보이도록 하는 것이다. 이 논문에서는 근원지와 도착지 간에 최단 경로를 한 번에 설정하면서 더미 패킷의 과도한 생성을 억제하는 패킷 전송 프로토콜을 제안한다. 시뮬레이션을 통해 통신 경로상의 노드 위치 기밀 수준을 검증한다.

The purpose of this study is to help understanding of east-west culture fusion in fashion since 2000 years, to play a guideline's role in the development on fashion designs study. The methods of this study are academic literatures as well as practical study through case studies about actual works. Tendency of east-west culture fusion in fashion since 2000 years is shape and performance, pattern, accessary. Shape and performance are reinterpreted through east folk fashion transforming on west fashion, pattern shows traditional pattern of each nations, but letters of typical of each nations appears for new pattern which expresses nation identification. Accessary is in the harmony with east -west fashion culture like that without transform. Aesthetic value of east-west culture fusion in fashion since 2000 years is summerised opening, co-ownership, and amusement. First, opening is positiveness of acception and acknowledgment for other. Second, co-ownership turns towards humanism, and proves participating in globalism and really global village. Third, amusement is to express freedom, and to reveal privately emotion concealing in public area.

In this paper, an informed watermarking algorithm is proposed that aids in concealing packet loss errors in video communications. This watermark-based error concealment (WEC) method embeds a low resolution version of the video frame inside itself as watermark data. At the receiver, the extracted watermark is used as a reference for error concealment. The proposed DCT-based algorithm employs informed watermarking techniques in order to minimize the distortion of host frames. At the encoder, a predictive feedback loop is employed which helps to adjust the strength of the data embedding. Furthermore, the distortion of the DCT coefficients introduced in the embedding can be removed to a considerable extent, by employing bit-sign adaptivity. Simulation results on standard video sequences show that the proposed informed WEC scheme has an advantage of 3$\sim$4 dB in PSNR over non-informed WEC and that even a non-informed WEC is still superior to conventional error concealment techniques.

Contemporary costume by the 'Deconstruction' from the outside has shown disclosure, destruction, poverty and analysis. The conclusion of this thesis as follows, 1. The Deconstruction of disclosure by infra disclosed the underwear and inner structure outside, which has deconstructed a fixed idea i.e.'underwear must be in outwear', modesty versus immodesty and disclosure versus concealment. 2. The Deconstruction of destruction originated in punk look has rejected traditional manners and utility, at the same time, it has shown the ambivalence i.e. completeness versus incompleteness, making versus destructing by slashes, rips, fringes. 3. The Deconstruction of poverty has appeared as French avangarde mode, little black dress by Chanel, second hand style by hippy, blue jean, granny look, especially Rei Kawakubo's poor look influenced by Zen Aesthetics and post punk. It has looked like old and worn out dress by doing patchwork, dye, decolor, rip, fray, which has shown the decentring by concealing the body than disclosing, rejecting snobbery. 4. The Deconstruction of analysis, seemingly partial and patched is a violation only of our expectation of clothing's unbroken entity though it has looked like a fragment. The completeness and coherence of it is made more evident by its breach, void, and bond like a poetic language. As the result, disclosed, destructed, poor, and analytical costumes has expressed as an escape from the appearance which traditional aesthetic concept had pursued.

Secret sharing is an effective way of protecting secret messages. However, the traditional secret sharing schemes are considered meaningless due to malicious people attention which might raise risks. To overcome the weakness, this paper presents an effective secret sharing scheme with the functionality of cheater identification, based on meaningful QR code. The secret message will be split and concealed in the padding region of cover QR codes with the assistance of Latin square and it can be completely restored when all the involved participants cooperate. The concealing strategy exploits the characteristic of Reed-Solomon (RS) code to ensure the strong robustness of generated QR code pseudo-shares. The meaningful QR code pseudo-shares help to reduce the curious of unrelated persons. Some experiments were done to evaluate the performance of proposed scheme. The results showed that the proposed scheme is feasible, efficient and secure compared to the other existing schemes. It also achieves a higher secret payload and maintains stronger robustness.

The Purpose of the study was to understand the experience of chronic renal failure patients for the qualified individual care for them. The purpose of this study was to explore the experience of patients living with chronic renal failure and to identify the meaning and structure of their experience. The subjects were four patients, two females and two males. The age range was from 21 to 54. Data was collected with a few in-depth interviews by the authors until the data was fully saturated. The framework and methodology of this study was based on Parse′s "Human Becoming methodology," an existential phenomenological research methodology. The findings of this study were as follows. Three experience structures of chronic renal failure patients were : 1. Sufferings and conflicts originated in the frustration caused by uncurable disease. 2. Dependence upon God and significant others with complex emotions. 3. Acceptance of sufferings, emerging hope for serving people, and gratitude for living. In conclusion the experience of chronic renal failure patients could be described from the findings (three structures) as "Experiencing the sufferings, conflicts originated in the frustration caused by uncurable disease, dependence upon God and significant others with complex emotion, acceptance of the suffering and hope for serving people, and gratitude for living." The three structures of the lived experience of patients with chronic renal failure, the findings of this study, could be explained by the three concepts of "Theory of Human Becoming," the first structure could be explained with values, the second with revealing-concealing, and the third with transforming.

The endowed privilege to an established profession acts as an important motivation related to professionalization of occupations. The established profession enjoys cognitive, legal, and economic privilege. This study analyzes the professionalization process of interior design. Specifically, the study evaluates the suitability of the body of knowledge and professional ethos(i.e., protection of citizen's health, safety, and welfare), while analyzing the professionalization of interior design in the United States. The research aims at proposing a reference point for the professionalization of Korean interior design. Utilized data include research paper, court sentencing, and reports published by related professional organizations. The study concludes that 3E's are a means of professionalization of interior design, while separating interior design from interior decorating. In addition, there is no evidence to the protection of citizen's HSW. Rather, it increases service costs and restricts the job opportunities. When the public is not persuaded, the argument related to the necessity of license for the protecting citizen's HSW can be consumed as a mere rhetoric, concealing intentions for formulating a cartel. Thus, this study proposes that the professionalization of interior design may focus on the establishment of identity and body of knowledge, which are specific to interior design.

One of the curiosities harbored most by anthropologists may be why women are so different from men physically. One of such differences must be the breast. Female animals do not have such a swollen breast even when they nurse their young. We can find many Western garments highlighting the breast, but in Korea the tradition has been that the breast should not be highlighted. It was because the large breast was deemed useful that Western people appreciated it highly. In general, it is conceived that to ancient Westerners' eyes, the nursing function of the breast was very mysterious, because the food supplies were insufficient. Although the size of a breast does not affect its nursing function, Westerners may have thought that it did. To the contrary, in the societies with rich agricultural products, the breast was not much emphasized as the reproductive organs. Since people are more and more concerned about their body and the breast or one of the body parts characterizing the femininity is regarded as an important element of design, it may well be significant to research into the breast designs for development of the fashion design. With such basic conceptions in mind, this study was aimed at reviewing the artworks featuring women's breast and their historical background and thereupon, analyzing the aesthetic values of the breast-featuring designs by dividing them into four categories in large.
