Recently, the traditional call center, which has an important role as the customer's primary contact point, has been transformed into the omni-channel contact center which supports an additional variety of access channels in addition to phone calls in order to improve customer accessibility and convenience. The omni-channel contact center has agents on each channel which are vital in determining the response rate and waiting time for the customer. In traditional call centers, agents can be assigned to a call based on the characteristics of the call, however in omni-channel contact centers, the characteristics of issues vary and come in through multiple channels, each with their own characteristics, making it difficult to assign the appropriate agent for the issue. Customers must also be processed at the same time, adding an additional layer of complexity to the issue. This paper analyzes and simulates an omni-channel contact center that accommodates email, chat, voice calls and video consultation, and investigates how to optimize the allocation of agents.

Parylene-C which was mainly used for industries such as electronics, machinery and semiconductors has recently been in the spotlight in the medical field due to its properties such as corrosion resistance and biocompatibility. In this study we intend to derive a plan to improve the bonding strength of Parylene-C coating with the SUS304 base material for medical use which can be applied to various medical fields such as needles, micro needles and in vitro diagnostic device sensors. Through plasma pretreatment the bonding strength between Parylene-C and metal materials was improved. It was confirmed that the coated surface was hydrophobic by measuring the contact angle and the improvement of the surface roughness of the sample manufactured through CNC machining was confirmed by measuring the surface roughness with SEM. Through the above results, it is thought that it will be effective in increasing usability and reducing pain in patients by minimizing friction when inserting medical devices and in contact with skin. In addition it can be applied to various application fields such as human implantable stents and catheters, and is expected to improve the performance and lifespan of medical parts.

인터넷데이터센터는 현대 IT산업의 중심설비로서 수십 MW의 전력을 소비하는 집중부하형태를 취하고 있다. 인터넷데이터센터의 특성상 전원의 신뢰성을 높이기 위하여 무정전전원장치(UPS)를 사용하는 것이 필수사항이다. 따라서 기존의 교류방식은 (교류-직류), (직류-교류), (교류-직류)의 3단계 전력변환이 필요하여 전체 급전계통의 효율저하를 가져온다. 이에 비하여 직류급전방식은 기존 계통 망에 연결하기 위한 (교류-직류) 1단계의 전력변환만 필요하므로 효율을 크게 개선할 수 있을 뿐만 아니라 전원의 신뢰도를 높일 수 있다고 알려져 있다. 본 논문에서는 인터넷데이터센터 내에 220V교류방식과 300V직류방식의 시험용 급전계통을 구축하고 똑같은 부하운전 조건에서 실제의 급전효율을 측정하였다.

유무선 네트워크 기술의 급격한 발전 및 개인용 휴대 장치의 보급 증가와 그에 맞물린 소셜네트워크 서비스 등의 활성화로 인해 데이터의 전송량이 폭발적으로 늘어나고 있으며, 이러한 추세는 향후 지속될 것으로 전망된다. 이에 데이터센터의 수요가 증가하고 있으며, 확장 및 유지보수가 쉬우면서도 높은 성능을 갖는 시스템에 대한 요구가 높아지고 있다. 본 논문에서는 데이터센터 네트워크의 구성요소를 분석하고 각각의 지연시간을 알아보았으며, 그 중 확장 및 유지보수가 쉬우나 상대적으로 지연시간이 높은 이더넷을 데이터센터에 적용하였을 때 지연시간 개선을 위한 방법으로 Intel DPDK를 적용할 경우, 미적용시와 비교하여 약 86%의 지연시간 감소를 확인하였고, 추가 향상 방안을 조망하였다.

This study analyzed universities's entrepreneurship education curriculum and variety programs through visiting to five entrepreneurship centers. Through these analyzes, the study presents a basic frame work for prosperous entrepreneurship education in Korea. We have selected for visiting research universities in the middle east of the United states; University of Iowa, University of Missouri(Kansas City), Saint Louis University, University of Louisville and George Washington University. We visited entrepreneurship center of each university in order to have in-depth interview with professor who is responsible for building entrepreneurship curriculum and administrative director of entrepreneurial programs so that we research how university progresses entrepreneurship education at undergraduate level. The study, at the time of 61 universities selected for LINC project by the Korea Ministry of Education who expects Industrial-Academia cooperative effects just installed each entrepreneurship center, analyzed case study of operational practice and entrepreneurship education curriculum for the effective operation of entrepreneurship centers in universities. We believe that the study will be able to provide a richer and more accurate information and ideas since the all the analysis is based on the firsthand interview by visiting.

The purpose of this study is to verify qualitatively and quantitatively practitioners' perceptions of functions and roles of community child center which plays a pivotal role in afterschool care in Korea. To achieve its purposes, we investigate environments, services, workers, service users, and delivery systems of community child center. As a result, 4 types of perception of community child center(service integration-oriented type focusing on professional workers, care-oriented type based on child care center's physical environment, delivering service-oriented type working in collaboration with schools, and individual case management-oriented type) were examined. These results were also classified into two categories. One focused on the importance of workers and supports for service environments. The other focused more on the functions of community child center to find commonality and originality in other afterschool care systems. This study can be valuable in understanding practitioners' different perception on functions and roles of community child center which have not yet been confirmed statistically. The results allow us to apply diverse practitioners' perceptions to the practice, and to elicit discussions regarding improved practice directions for managing community child center. It also can provide useful baseline data in policy decisions and enforcement.

In this paper, a seasonal variable selection method using the spectral analysis accompanied with seasonal linear model is suggested. The suggested method is applied to the prediction of intra-day call arrivals at a large North American commercial bank call center and a signi cant intra-month seasonal variable I detected. This newly detected seasonal factor is included in the seasonal linear model and is compared with the seasonal linear models without this variable to see whether the new variable helps to improve the forecasting performance. The seasonal linear model with the new variable outperformed the models without it in one-day-ahead forecasting.

IT 아웃소싱은 IT 서비스 관리에 있어서 가장 중요한 전략 중 하나로 인식되고 있다. 조직의 핵심 역량에 집중하면서 부차적인 IT 업무는 외부로부터 지원을 받는 IT 아웃소싱 전략은 조직의 효율과 성과를 높일 수 있는 효과적인 방안이면서, 보안에 대한 우려와 IT 서비스 공급자에 대한 의존도를 높이는 부작용을 동반하고 있다. 본 연구에서는 국내 민간 기업 데이터 센터의 IT 아웃소싱 전략과 운영을 분석하였다. 국내 주요 IT 서비스 전문 기업 3개사와 금융그룹 1개사의 데이터 센터에 대한 심층 인터뷰를 바탕으로, 데이터 센터들의 IT 아웃소싱 조직 현황, 아웃소싱 결정 요인, 아웃소싱 저해 요소와 해결 방안 등 전반적인 IT 아웃소싱 전략과 운영을 살펴보았다. 국내 주요 기업들의 데이터 센터는 IT 유지 보수, 인프라 기반 운영 등의 업무를 아웃소싱 대상 업무에, 그리고 IT 기획 전략 컨설팅, 시스템 기획 개발 등의 업무는 인소싱(in-house sourcing) 업무로 분류하고 있었다. 또한 IT 아웃소싱 결정 요인으로 내부직원의 역량, 비용, 리스크 등이 있었고, 정량적인 분석보다는 정성적인 판단에 의해 아웃소싱을 결정하고 있었다.
