최근 온라인 유통의 약진 속에서 대표적인 오프라인 유통인 백화점 채널이 예전에 비해 경쟁력이 약화 되었다는 평가를 받고 있다. 이는 유통채널로서의 경쟁력이 약화 된 것이지, 복합 문화 센터의 경쟁력은 나날이 느는 추세다. 길이 복잡한 백화점에서 비대면 방식으로 시설 안내 및 길 찾기 동행, 사용자 나이 및 성별에 따른 매장 추천, 고객 센터 연결 등을 고객에게 제공하는 가이드 로봇을 통하여 경쟁력을 키우고자 해당 서비스를 제안한다.

The purpose of this study is to evaluate the effectiveness of online and offline blended education for hygiene and safety management of children's foodservice operations in Eunpyeong-gu. For the teachers of the children's foodservice operations, two online sessions and one offline session were conducted with different educational themes each time. In terms of satisfaction with the education, the online program 'Mission Possible' scored 4.8 points and the collective education of teachers and staff scored 4.6 points, indicating that the training composition and communication with the person in charge were high. In other field opinions, it was found that online and offline education according to the situation was very helpful in the overall management of the children's foodservice operations. With fewer face-to-face opportunities, there were difficulties in on-site support and management. To supplement this, various programs were applied to help children's foodservice operations provide healthy and safe meals and snacks.

It is very important to find out causes of strip pinching for the high quality of products and fer the stable operation of rolling system. We have examined the strip pinching from three points of view to find out the causes of strip pinching in rolling system: strip shape, rolling operation conditions, and behavior of strip. Wedge, off center, and difference of rolling force through CMD(Cross machine direction) are found to possibly provide major initial causes of strip pinching. Generally strip pinching occurred in the tail of strip. Thus, computer simulations by using a FEM code were also carried out to find out the initial mechanism of strip pinching depending upon the force and geometric boundary conditions at the time of strip tail rolling. The strong compression force effect due to the sudden release of strip tail from the work roll and non-uniform strip tail shape (ex. Fish tail) across the CMD were found to provide possible major causes of strip pinching.

In this study, for a natural cosmetics market, we sought to explore alternatives that can replace polyvinyl alcohol (PVA) of peel-off packs. A peel-off type pack was prepared by combining pullulan, a water-soluble polysaccharide, and other polysaccharides (sodium hyaluronate, cellulose gum, hydroxyethyl cellulose, sodium alginate, corn starch), and the pH, viscosity, and stability against temperature of each peel-off type pack were confirmed. The thickness and tensile strength of the manufactured film were measured for comparison with the PVA peel-off type pack, and applicability, drying speed, and removal degree were measured. Among them, the pullulan-sodium hyaluronate peel-off type pack showed excellent film formation ability to replace the peel-off type pack containing PVA with 5.12% thin film thickness and 4.23% high film tensile strength. When applied to actual skin, the degree of spread of the pack, the usability that can be uniformly applied, and the formation and removal strength of the film when removed after drying were also similar to the peel-off type pack containing PVA. Therefore, it was confirmed that the film formed of pullulan-sodium hyaluronate showed enough physical properties to replace the PVA of the peel-off type pack as a natural peel-off type pack.

The purpose of this study is to examine the relationships among vividness, consensus, reliability, homogeneity, ties and acceptance of WOM (Word Of Mouth), consumer attitude, SNS WOM transmission, offline WOM transmission, and visit intention perceived by married women consumers who learned SNS WOM regarding restaurants. This study performed a survey targeting married women, focusing on broadcasting stations, department stores, major supermarkets, government offices, and cultural centers in Busan. The surveying period was from March 1, 2014 to March 31, 2014. 304 questionnaires were used for the final analysis. As a result of the analysis, it could be concluded that vivid and reliable SNS words raise the level of acceptance of WOM, reliability makes consumer attitude positive, and homogeneity raises the level of acceptance of WOM, consumer attitude, SNS WOM transmission, and offline WOM transmission intention. In addition, it could be confirmed that acceptance of WOM have significant effects on consumer attitude and offline WOM transmission, and consumer attitude have positive effects on SNS WOM transmission, offline WOM transmission, and visit intention. Lastly, it could be learned that SNS WOM transmission and offline WOM transmission have significant effects on visit intention.

In Korea, a variety of policies for the regional cultural industry development have been carried out: the promotion policy of cultural industry cluster, the establishment of cultural industry support center, and the construction of cultural industry complex and the supporting works for the cultural research center. The cultural industry has a dual character of the manufacturing industry and the service industry. The cultural industry of Gyeongbuk province is mostly centered upon small manufacturing firms with low value-added. Thus, it is desperately in need of the building-up of the enterprise supporting system. However, it is difficult to expect that private business service finns can be activated. In this sense, local and regional governments seek to establish so called 'the cultural contents support center'. However, it is not clear whether the center is an organization for the production of cultural contents or an agency for the support of cultural contents industry. Also it does not prepare any major functional introduction facilities and performing programs. Most of all, it is necessary to establish a proper orientation that 'the cultural contents support center' must be not an organization for the direct production of cultural contents, but an organization supporting cultural industry by way of providing cultural industry enterprises with what is necessary for the production of cultural contents. Also, a system for the establishment of business fitting support policy that can cover the whole sectors of cultural industry must be prepared. Furthermore, a synthetic support system for the cultural business associated industries centered on specified sectors such as films, edutainment, and storytelling must be constructed. Finally an environment for the creation and inducement of cultural industry enterprises, and for the active participation of enterprises and related groups in the promotion planning and in the policies of cultural industry must be built along with on- and off-line networks.

전력계통 컨트롤센터에서 사용되는 SCADA/EMS 응용프로그램은, 전력계통의 해석을 위해 특정한 포맷의 입력데이터 파일을 사용하는 일반적인 오프라인 응용프로그램과는 달리, 물리적 특성이 통합된 전력계통 데이터베이스 기반위에서 수행된다. 응용프로그램들은 데이터베이스를 통해 필요한 데이터를 상호 교환하며, 개별 응용프로그램은 데이터베이스와 연동하는 사용자화면을 통해 컨트롤센터의 운전원과 상호작용을 하게 된다. 따라서 전력계통 데이터베이스 기반위에서 수행되는 EMS용 응용프로그램을 개발하기 위해서는 먼저 프로그램 고유의 기능적인 측면은 물론 운전원을 포함한 여러 사용자를 위한 프로그램 운용적인 측면의 요소까지 종합 분석하여 필요한 기능과 화면 그리고 그에 따른 데이터를 도출해야 한다. 도출된 기능 및 화면설계안에 따라 개발된 프로그램과 사용자화면은 모든 입출력 데이터들이 반영된 데이터베이스와의 인터페이스를 통해 통합 EMS용 응용프로그램으로서의 형태를 갖추게 된다. 최종적으로 응용프로그램은 사전에 준비된 시험절차에 따라 검증(프로그램의 정확성, 신속성 그리고 신뢰성을 평가)과정을 수행한다. 본 논문은 전력IT 국가전략과제로 개발 진행 중인 한국형 EMS(K-EMS) 응용프로그램의 개발 프로세스와 각 프로세스에서의 고려사항들을 소개함으로써, 한국형 EMS를 위한 응용프로그램의 추가 개발 혹은 전력계통 데이터베이스 구축과 이를 활용한 응용프로그램의 개발을 위한 방법론을 제안하고자 한다.
