인터넷이 널리 보급됨에 따라 온라인 상에서의 활동은 보편화 되었고 사용자들은 자아를 표현하고 성장시키는 것에 대하여 더욱 다양하고 확장된 환경을 요구하게 되었다. 사용자 간의 상호작용, 자신을 대표하는 상징물과 현실세계의 자아와의 상호작용은 매체의 몰입의 한 요소로서 중요하다. 이는 게임에서도 마찬가지이며, 플레이어의 게임 속 상황이나 역할에서의 행동은 자신만이 아닌 다른 사용자에게도 직간접적인 영향을 미치게 된다. 플레이어의 모든 행동은 인터페이스를 통하여 이루어지게 되는데, 다변화적인 상황에서 역할을 수행하면서 사용자는 자신의 성향과 편의에 부합하는 인터페이스를 원하게 된다. 본 연구는 사용자 맞춤형 인터페이스(Customized UI)를 연구하는 한 과정으로, 게임 인터페이스를 하나의 매체로 선택하여 사용자 맞춤형 인터페이스를 제공하는 것이 매체 몰입을 향상 시킬 것이라는 가설을 바탕으로 진행되었다. 게임 인터페이스에서 개인의 취향에 따라 인터페이스를 차별화 시킬 수 있는 Add-ons 기능이 보편적으로 사용되고 있는 MMORPG 'WOW'의 플레이어들을 대상으로 설문과 분석을 한 결과 게임상의 다양한 상황과 역할에 따라 요구되는 인터페이스의 복잡수준은 차이가 있을 뿐만 아니라, 사용자의 개개인의 요구를 충족시키는 맞춤형 인터페이스를 제공하는 것은 게임의 지속적인 흥미를 유발하고 몰입을 강화시킨다는 결론을 얻을 수 있었다.

This study was carried out to improve the thermal insulation properties of wool and wool- like fabrics by treating the fabrics with polyethylene glycol, to evaluate the fabric hand of PEG treated wool and wool-like fabrics and to grade up the fabric hand of the treated fabrics by treating with softening agents. Wool and wool-like fabrics were treated with high molecular PEG-8,000 by PDC. The thermal release/storage properties were measured on a DSC. Hand of specimens were evaluated by KES-FB system. The results were as follows; 1. PEG-treated fabrics showed thermal storage and thermal release properties by DSC and the heat contents were generally proportional to the add-ons. 2. PEG-treated fabrics showed higher Koshi and lower Numeri and Sofutosa values due to lower tensile energy and recovery and higher bending rigidity and shear stiffness as the add- ons increased. 3. PEG-treated fabrics showed much lower bending rigidity after softening agents treatment.

퀘스트는 게임 스토리의 최소단위로써, 퀘스트 스토리텔링을 연구하기 위해서는 퀘스트 구조 분석이 필요하다. 본 연구는 퀘스트의 구조를 파악하기 위해, 구조주의 서사이론에서 프롭의 민담기능을 도입하였다. 프롭이 등장인물의 불변요소로 제시한 31가지 민담기능을 MMORPG 퀘스트에 대입하여 분석하였다. 그 결과 퀘스트의 필수기능(13개), 부가기능(5개)를 도출하였고, 이 기능들이 어떤 순서로 전개되는지 살펴보았다. MMORPG 퀘스트는 필수기능의 순서에 따라, 그리고 부가기능을 선택사항으로 하면서 진행되고 구조가 반복되는 패턴을 보여주었다. 이들의 기능을 적절한 요소에 활용한다면 퀘스트 스토리텔링을 강화하고 다양한 이야기를 이끌어 나갈 수 있는 방안을 마련할 수 있을 것이다.

The purpose of this study was 1) to estimate the improvement of thermal storage/release and moisture transport properties of PEG-treated acrylic athletic socks and suggest the optimum add-on for PEG treatment, 2) to investigate wear performance of untreated cocks and two kinds of socks treated with PEG of minimum and optimum add-on respectively, and 3) to consider the effect of thermal storage/release and moisture transport properties of PEG- treated socks on the wear performance and the subjective comfort zone. Thermal activities of specimens treated by PDC were evaluated on a DSC by measuring the heat of fusion on heating and the heat of crystallization on cooling. Moisture regain, absorption speed, wickability, water retenti on value, and water-vapor permeability were measured. In the wear trials that the subjects performed a subsequent exercise protocol wearing three differently treated socks in a conditioned environment ($14\pm2^{\circ}C$, 65$\pm$2% R.H.), microclimate temperature and humidity, and subjective wear sensations including thermal sensation, wettedness, softness, fit, and overall comfort were obtained. PEC-treated specimens with more than 20% add-on showed thermal storage on heating and thermal release on cooling by a DSC and the heat contents of treated ones were generally proportional to the add-ons. Moisture transport properties were highly improved after PEG treatment and increased rapidly with increasing add-on. The tendencies were, however, relaxed above 50% add-on and the treated knits were much stiffer above that add-on. In the wear trials of untreated, PEG add-on 20%, and 50% acrylic socks, the changes of microclimate temperature of 50% socks were significantly less than that of 20% socks. PEG add-on 50% socks showed significantly less changes of microclimate humidity than other two kinds of socks. Three kinds of socks showed significant differences in overall comfort and add-on 50% socks were accepted more comfortable than other two kinds of socks. Comfort zone of foot was extended after PEG treatment on socks and it implied that the subjects wearing PEG- treated socks felt comfortable in wider ranges of microclimate temperature and humidity.

Designing effective navigation aids for customer interfaces is critical for the success of cyber shopping malls. Navigation aids can be classified into either basic ones which are based on the structure of the malls or add-ons which are not. Add-on navigation aids provide various short-cuts to promote efficient traversal in the cyber shopping malls, but too many of them would increase the complexity of the customer interface. Metaphors have been used widely for the design of add-on navigation aids, but little research evaluates their impact on the processes and outcomes of customers behavior in cyber shopping malls. This paper presents an empirical study that investigates the navigation process of customers and the subjective evaluation of their shopping experience. This research implemented two versions of a test-bed cyber shopping mall according to different metaphors used; one based on a spatial metaphor, and the other based on a non spatial metaphor. The results of the experiment indicate that navigation aids based on the spatial metaphor were used more frequently, which resulted in better understanding about the entire structure of the cyber shopping malls, which in turn led to an increased ease of finding target items and also a more pleasant shopping experience. The benefits of navigation aids based on the spatial metaphor became more evident when customers were looking for ad-hoc category items rather than common items. This paper presents plausible explanations for the results and implications to the design of navigation aids for cyber shopping malls.

인터넷을 통하여 제공되는 대부분의 웹 서비스들은 웹 브라우저를 통하여 사용자에게 제공된다. 웹 브라우저는 텍스트 형태의 웹 페이지를 서버로부터 수신하여 해석하고 사용자에게 보여준다. 웹 브라우저는 추가적으로 설치 할 수 있는 각종 기능들을 통하여 확장성을 제공한다. 하지만 추가로 설치 할 수 있는 기능들도 웹 페이지에 접근하여 내용을 위/변조 할 수 있다는 점에서 웹 브라우저를 통한 웹 서비스는 보안상 문제점을 내포할 수 있다. 웹 브라우저는 웹 페이지정보를 DOM구조의 형태로 메모리에 저장한다. 웹 페이지의 변조를 방지하기 위한 방법으로는 DOM구조의 특정 부분에 해쉬(hash)값을 적용하는 방법이 있다. 하지만 웹 페이지의 특성상 해쉬를 이용한 대응방안이 효과를 발휘할 수 없는 부분이 있다. 즉, 사용자가 직접 입력하는 부분은 정해진 입력 값이 아니기 때문에 미리 해쉬 값을 계산 해 놓을수도 없고 따라서 임의로 변조되는 것을 막을 수 없다. 본 논문에서는 웹페이지에 입력되는 사용자 입력 값의 위조나 변조를 방지 또는 탐지하는 방안을 제안한다. 제안 방법은 사용자가 키보드를 사용하여 입력하는 입력 값을 저장 해 놓았다가 웹 브라우저가 입력 값을 전송하는 순간 저장된 입력 값과 전송되는 값을 비교하여 변조 여부를 파악한다.

This work aims at analyzing the comparative feature about female flight attendant uniform designs of Korean and Asian region low cost carriers and providing some basic materials for development of these airline companies. As a research method, examinations were carried out on attendant's uniform both theoretically and empirically. Comparison of uniforms was made among the five Korean carriers and ten typical Asian carriers for empirical research. Results showed the followings. First, all Korean low cost carriers were characterized as formal style except Jin Air. Unlike this, Asian low cost carriers appeared as diverse including formal, semi formal, and casual styles with a uniquely differentiated image. Second, all carriers applied their own symbolic color to their uniform. Third, logo or symbol was adopted as a pattern on scarf in the two Korean companies but it didn't take effect practically. For those Asian carriers, embroidery was used on jacket, jumper and collar. They utilized even a merchandising character to put emphasis on airline image. Fourth, diverse petty items with a decorative effect were used in the case of Korean low cost carriers. In the changing period of uniform, nothing much was changed and remained almost the same as before. Those in the Asian region were characterized with the smallest number of items and the preclusion of decorative add-ons on uniform.

PTCA(1,2,3-propanetricarboxylic acid) and BTCA(1,2,3-butanetetracarboxylic acid) are selected as new nonformaldehyde agents for ester crosslinking of cotton cellulose to replace the traditional DMDHEU reagent. A goal of this research is to propose unknown ester mechanism of cotton cellulose by PTCA or BTCA using crystal structure model suggested by Meyer and Takahashi. In pursuit of these goals, we have treated 100% cotton broad cloth with PTCA or BTCA and different catalysts. They were used with $NaH_2PO_2,\;NaH_2PO_4,\;Na_2HPO_4,\;NaH_2PO_2,\;Na_3PO_4,$ catalysts to produce nonformaldehyde fabric finishes. Treatments were applied to all cotton fabrics using a pad-dry -cure process. The esterfication of cotton treated with BTCA or PTCA was investigated using Fourier transform infrared(FT-IR) spectra and the breaking strength, abrasion retention and discoloration properties were determined to prove the durable finished fabrics. Patterns with respect to abrasion resistance were more complex. Because PTCA and BTCA add-ons were comparable, the data suggest that the more effective catalysts, $NaH_2PO_2$ and mixed phosphate $NaH_2PO_2/NaH_2PO_4$) are effecting either a great number of crosslinks in the cotton or producing crosslinks that differ in actual structure.

The purpose of this study was to evaluate the thermal properties of ceramics coated nylon fabrics by determining far infra-red emissive properties, heat storage/release and thermal insulation. Far IR emissivity and emissive power were measured for 7~ 140n at 50'C . Three types of ceramics such as cordierite with $\alpha$-alumina, a-alumina with titanium oxide and a-alumina were chosen as specimens. Cordierite with $\alpha$-alumina was chosen to treat on the fabrics due to the good emissive properties on the fabrics. Add-ons and contents of ceramics were analyzed for ceramics and/or polyurethane coated fabrics. For the physical properties, thickness and air permeability were measured. Results showed a difference in the emissive property between ceramics themselves and ceramics coated fabrics. In the ambient temperature, there was no diffenence in emissivity among the different ceramics contents. Thermography showed that when the fabric was heated with the light, surface mean temperatures of fabrics were increased as the contents of ceramics increased, and the heat storage property was confirmed. In case of same thickness and air permeability, the thermal insulation value increased as the contents of ceramics increased because of increasing heat storage and Far IR reflectivity. So there were absorption and heat storage of ceramics for Far IR from human and reflection to human between ceramics coated fabrics and human.
