최근 기업들은 과거처럼 양적 성장위주의 경영관리체제에서 벗어나 변화하는 경영환경에 부합사는 새로운 변신을 강력히 추진하는 전력도구로서 아웃소싱을 점차 고려하고 있다. 이러한 정보기술 아웃소싱의 성공과 실패를 결정짓는 중요한 요소중의 하나는 벤더(vendor)와 클라이언트(client)간의 힘의 균형관계다. 본 연구는 벤더와 클라이언트간의 힘의 균형관계가 아웃소싱계약의 엄격성 정도와 갈등관계에 미치는 영향과 계약의 엄격성 정도가 갈등에 영향을 주는 정도를 조사했다. 실증분석결과 첫째, 힘의 균형과 갈등관계에 있어서는 정보력 불균형이 서비스 질 문제갈등과 이윤문제갈등에 부(-)의 영향을 주며, 준거력 불균형이 이윤문제 갈등에만 부(-)의 영향을 주는 것으로 나타났다. 둘째, 힘의 균형과 계약의 엄격성 정도에 있어서는 정보력불균형이 계약수정정도 및 도구개발정도, 전제내용기술정도 모두에 각각 부(-) 의 영향을 주며, 준거력 불균형 또한 계약수정정도 및 도구개발정도, 전제내용기술정도 모두에 각각 부(-)의 영향을 주는 것으로나타났다. 마지막으로, 계약의 엄격성정도와 갈등관계에 있어서는 도구개발정도만이 비용문제, 서비스질문제, 이윤문제 갈등에 각각 부(-)의 영향을 주는 것으로 나타났다.

IT서비스의 아웃소싱을 통해 기업은 핵심역량에 집중하므로써 비용절감을 통한 경쟁력확보를 위해 노력해왔다. 서비스데스크는 단순히 고객의 불만사항이나 장애처리를 담당하는 영역을 넘어 IT아웃소싱에서 고객사와 IT서비스 제공사의 단일접점 뿐만 아니라 IT서비스제공사간의 원활한 의사소통을 통해 협업을 이루어가고 있다. 신세계 이마트의 무인점포시스템과 에릭슨코리아의 토털IT아웃소싱의 사례 중심으로 서비스데스크의 역할과 기능을 살펴본다.

This study was conducted to improve the use experience of elderly people in fast food kiosks which are actively utilizing 'un-tact' technology. First, the Kiosk design analysis criteria were discussed through literature research. Then, the UI screens of McDonald's, Lotteria and Burger King, which are currently serving kiosks in Korea, were divided into colors, layouts and buttons. Next, the usability evaluation and survey of the elderly revealed problems with the interface design of the current kiosk. As a result, older people do not recognize buttons without an outline as buttons, and errors occur when layout changes or when viewing is complicated. In addition, horizontal navigation and vertical layout menus were error-free, and the design of buttons was error-free with the same color for the same function. Research shows that the Kiosk UI design is preferred by older people. First, buttons in the form of outline or solid are recommended. Second, vertical binding of buttons combined with images and text is recommended. Third, the screen layout should be consistent with the direction of view flow and manipulation, and should avoid increasing the number of menus and information. Fourth, page navigation is recommended in horizontal form and menu arrangement is vertical form. Finally, buttons that perform the same function are efficient for buttons to use the same color, and for different functions, applying a complementary colors can reduce confusion.

This research aims to study the needs of the trail runners as trail running has become a popular outdoor activity, and give suggestions for high functional outdoor menswear design that can satisfy the needs of the highly demanding taste of runners. The design development is as follows: 1) The design had to be made of lightweight material and be easily packable in all situations, and 2) we also considered the ergonomic and compact fit for activity, 3) the functional location of high functional fabric, 4) the reflective use and layering system giving a wide range of outdoor workout time and 5) the trend in 2016 S/S active sports and outdoor wear. Based on the above elements, the men's outdoor wear design has been developed for trail running in spring and summer. The design development includes a total of 7 items. The design focused on lightweight, availability of packaging, "comfortability" and freshness in activity, functional suitability of location of highly functional materials and the layering system to protect body temperature under the changing environment. In particular, the layering system was implemented to provide ventilation, and it was done in body parts that released the most body heat. Therefore, mesh materials were actively used on the side panel, sleeves and center of the back piece for necessary sweat emission without any problems and ventilation for trail running.

Many web services which use OAuth Protocol offer users to log in using their personal profile information given by resource servers. This method reduces the inconvenience of the users to register for new membership. However, at the time a user finishes using OAuth client web service, even if he logs out of the client web service, the resource server remained in the login state may cause the problem of leaking personal information. In this paper, we propose a solution to mitigate the threat by providing an additional security behavior check: when a user requests to log out of the Web Client service, he or she can make decision whether or not to log out of the resource server via confirmation notification regarding the state of the resource server. By utilizing the proposed method, users who log in through the OAuth Protocol in the public PC environment like department stores, libraries, printing companies, etc. can prevent the leakage of personal information issues that may arise from forgetting to check the other OAuth related services. To verify our study, we implement a Client Web Service that uses OAuth 2.0 protocol and integrate it with our security behavior check. The result shows that with this additional function, users will have a better security when dealing with resource authorization in OAuth 2.0 implementation.

The increase in the consumption of outdoors sportswear is not because of an increase in sales from hiking enthusiasts but rather the general public's desire to wear them as everyday clothing. We expect that the market for the outdoors sportswear will grow gradually as people feel the need to wear extra outerwear for protection from wind everyday. Furthermore, as the consumers' demands for these outerwear increase, their desire for more variety increases as well. Five prominent domestic brands were chosen for the analysis. The selection method included two factors: 1) the brands with the highest sales figures in the last five years 2) brands that were mentioned most frequently in fashion articles (i.e apparel news, fashion biz) from 2009 to 2011. the goal is to analyze each of the brands' different concepts of outerwear design so that the results from the analysis can be used to develop better more diverse products in the market and satisfy with the consumers' need. In the end we have to develop better technology and more diverse designs in order to meet the increase in consumers' need. They are interested in sportswear and functional clothing; we have to satisfy their need. for diverse selections in their outerwear and this is especially the case with consumers in their teens and twenties.

Despite both domestic and overseas markets are depressed due to the global financial crisis - the apparel industry is no exception, the market for the outdoor wears including the hiking ones has been recording a high growth rate, making the outdoor wear a high growth industry. The purpose of this study was to provide some basic data useful to our outdoor businesses to help them respond to consumers' needs in the rapidly growing outdoor markets. For silhouettes, the point was given primarily to the oblique cutting to have it follow the human body curves and thereby, look natural and slim. Another point was given to the color schemes along the cutting lines, so that an effect of optical illusion could be created to make the wears look slim making use of lines and colors. On the other hand, in consideration of the rapidly changing weather conditions during hiking, the details were designed practically by setting appropriate hip lengths, using attachable/detachable hoods as well as applying the Velcro & rubber band-type set-in sleeves for the tail edges. As discussed above, the researcher analyzed the design elements for the outdoor wears and developed some sensuous designs meeting consumers' needs to help our outdoor wear businesses to expand their target base, while awakening them of the importance of the outdoor fashion.

Prestressed concrete girder bridge has been one of the most widely used bridges in the world because of its excellent construction feasibility, economic efficiency, serviceability, and safety. In certain situations, the prestressing tendon is supposed to be bent by the construction error and the radius of curvature at the continuous joint of PSC girders, and this leads to the loss of prestressing force. However, this kind of prestress loss is not considered in the design and construction processes. This study proves that the prestress loss occurs at the continuous joint due to the local bending of tendon by the construction error or the radius of curvature. Also, a method that can reduce this type of prestress loss is proposed, and proved by the experiment. The result shows that maximum 10% of prestress loss occurs at the continuous joint and the proposed block-out method can reduce the prestress loss ratio by maximum 5%, approximately. This means that the block-out method can enhance the prestressing efficiency of continuous PSC girder bridges.
