A small sized device with computing, communicating, sensing capability is changing our life. It will be deployed in the world and acquire a lot of data from the world. It is used for various applications such as military surveillance, environmental monitoring, structure health monitoring, building management, asset tracking, etc. In this paper we focus on USN middleware for asset tracking. A mobile asset is moving here and there within a specific area. The USN middleware tracks the mobile assets in real-time by using sensor nodes and notify their current positions to a user. To achieve the goal, the USN middleware provides some features related to the positions of mobile assets.. They are storing location data by using 3D indexing method, retrieving them by using spatio-temporal query, making trace of an asset, and retrieving the history data of an asset. In the paper, we developed USN middleware to adapt the requirements of asset tracking. It can help users increase the efficiency of their business related to mobile assets and make a valuable decision.

Since the 20th century, the business of railway was invaded by the invention of airplanes and vehicles in the field of the transportation of passenger and commercial products, however, in the 21st century, the fervent development of a high speed railway made possible the huge capacity of transporting passengers and commercial freight, so the railway industry is facing a new era of railway revolution. The 200 years old railway tradition includes the history of railway bridges built in areas of river, valley and metropolitan region and in that, the number of constructions of railway bridges that is composed of cable-stayed bridges is increasing as one of the most optimal bridges considering the quality of materials and the span of continuous-welded long rail. Thanks to the minimized effects of the fixed load on the stiffening girder section by delivering the fixed load which is applied to the pylon with the composition of elastic supporting points by using cables and the effective structural system that can throughly resist extra loads in addition to fixed load, the long-extended span of a bridge becomes possible. In this structural system, the load that is applied to the stiffening girder section forms a now pattern and in the process of these load delivery, there will be a necessity to examine the concentration of stress occurred in the cable-anchor system of the cable.

In this structural system, the load that is applied to the stiffening girder section forms a flow pattern and in the process of these load delivery, there will be a necessity to examine the concentration of stress occurred in the cable-anchor system of the cable.

해마다 반복되는 일본수상의 야수꾸니신사 참배는 한국정부의 심리를 자극하기에 더없이 적합한 외교소식이다. 아시아의 정상이라고 할 수 있는 두 나라 사이의 적대감은 단순히 60년이 지난 식민지시대의 역사로만 보기는 힘들다. 두 나라의 관계는 한국은 물론 일본의 경제성장을 위하여 고의적으로 소외시킨 식민지시대 후 외교수립의 영향을 보여주고 있다. 이 논문의 목적은 빈번히 무시되지만 명백하게 두 나라의 관계를 구체화한 한일기본조약의 역사를 밝히기 위해서이다.

In-situ measurement was made to evaluate chiller performance and thermal storage density of an ice thermal storage system. The system belonged to a big hotel and the measurement was conducted during late October. Owing to very small cooling load, the data logging was possible for a single thermal storage cycle. However, operation history of the chiller showed a relatively good spectrum of data for performance evaluation. COP and thermal storage density were calculated. The COP at full load was about 4.07, which was lower than $4.8\~6.4$ of new chillers. The measured storage density was about $10.9RT-h/m^3\;(=152MJ/m^3)$, which also was lower than a criterion of normal performance $(above\;13.0RT-h/m^3\;or\;181MJ/m^3)$. The study result provides technical basis for quantitative ESCO business scenario.

Purpose - The purpose of this paper analyzes the relationship between the Corporate Social Responsibility(CSR) and Corporate Value to estimate whether the characteristics of Firm can change this relationship. Design/methodology/approach - This paper utilizes the total 776 firms' data over the period 2014-2018, and develops a new ESG index which was estimated by PCA. Findings - First, the estimated ESG index implies that Large company has the highest value of CSR, while Medium sized and Small company have the relatively low one. And comparing to the case of 2014, the trend of ESG index in Large company does not decrease in 2018. Second, there is a clear and significant non linear relationship between CSR and corporate value, it implies that the U-shaped exists in the Korean Firms. Such a tendency is mush stronger in the Large company. Third, the new ESG index indicates that it takes more time to increase Firm value in the Medium sized and Small company while there is a high possibility of increasing value in Large company from the little gab between the threshold points and mean value of ESG. Research implications or Originality - The non linear tendency between the Corporate Social Responsibility and Corporate Value is strongly affected by Firm size and the relative high quintile of ESG, but it is less affected by Firm history.

The computer system validation consulting industry is growing as domestic GMP companies' overseas exports or advancements increase, and computer system validation has been mandatory in Korea since the 2010s, but domestic CSV consulting companies are small in size and have a short history, revealing many shortcomings in terms of service quality and customer satisfaction when conducting consulting. Research related to consulting has been mainly focused on management consulting and IT consulting, and research related to computer system validation is very insufficient. This study confirmed the effect of consultant competency and service quality on consulting performance, customer satisfaction, and intention to renew contract when performing computer system validation through empirical research on food, pharmaceutical, cosmetics, and medical device companies, which are representative companies in the GMP industry. As a result, it was confirmed that consultant competency and service quality had a significant effect on consulting performance, customer satisfaction, and intention to renew contract. In addition, it was confirmed that the reputation and expertise of consulting companies had a moderating effect on the relationship between consultant competency and consulting performance.

본 연구는 Kano모델을 활용하여 프랜차이즈 매장에 관한 다양한 품질요인들의 속성을 고객의 관점에서 분류하였다. 또한, 각 품질요인들이 고객의 만족 또는 불만족에 미치는 상대적 영향력을 분석해 보고자 만족지수와 불만족지수를 산출하였다. 자료 수집을 위해 외식 프랜차이즈 매장 방문 경험이 있는 서울 및 전국광역시 거주 성인들을 대상으로 온라인조사를 실시하였으며, 총 257개의 응답이 분석에 사용되었다. 분석 결과, 해당 품질요소가 충족이 되지 않는 경우 소비자의 불만으로 이어지는 요소에는 매장 청결도, 직원 친절도 및 숙련도, 편의시설 제공 등이 포함되는 것으로 나타났다. 프랜차이즈 사업에서 매장 간 음식메뉴의 구색, 가격, 품질수준, 인테리어, 고객서비스 절차 등의 표준화는 중요하게 생각되어 왔으나, 이 중 음식 가격의 동일성만이 고객의 불만족과 깊은 관계를 가지고 있었다. 충족이 되지 않아도 상관없지만 충족이 되는 경우 고객들의 호의적인 반응을 이끌어낼 수 있는 요소로는 외부기관으로부터의 수상 또는 인증 경력, 프랜차이즈 브랜드의 해외진출, 경품이벤트 및 사용금액에 따라 혜택을 주는 로열티 프로그램의 실시, 그리고 우수한 매장접근성이 해당되었다. 프랜차이즈 브랜드를 상대적으로 자주 이용하는 헤비유저의 경우, 정기적인 신메뉴 출시 또한 매력적인 품질요인으로 생각하고 있었다. 본 논문은 경영자가 우선적으로 관심을 두고 개선하여야 하는 부분과 경쟁력 확보를 위해 추가적으로 투자해야 할 부분이 어디인가에 대한 시사점을 제공해 준다는 점에서 연구의 의의가 있다.

항공기 제작산업은 고부가가치일 뿐만 아니라 국가적인 수출 유망산업으로서 현재 매년 수십억 달러에 달하는 항공기 부문의 무역 적자를 개선하기 위하여 반드시 이루어야할 사업이다. 현재 국내 항공 산업은 최초 아음속항공기인 KT-1을 시작으로 최초 초음속 항공기인 T/A-50 개발에 이르기까지 눈부신 발전을 이루고 있으며, 실전 배치와 국내외 각종 에어 쇼에서 그 우수성을 인정받고 있다. 현재도 계속 진행되고 있는 차기 전투기 사업이나 공격헬기사업 등을 고려한다면, 차세대 국내수송기 개발 전망은 매우 밝은 편이다. 또한, 공군 해외파병의 역사가 월남전부터 대테러전과 최근의 이라크 자유 작전까지 수송기를 이용한 항공수송이 주 임무가 되었던 점을 감안한다면, 장래 우리 군과 국산 수송기의 우수성을 알릴 수 있는 기회 또한 많을 것으로 판단된다. 본 연구는 우리나라에서 수송기를 개발할 경우 적정 규모에 대해서 AHP기법을 이용하여 알아보고자 하는 목적에서 시작되었다. 평가는 한국형 중형 여객기 개발 규모 연구에 적용되었던 평가기준을 근거로 운용성, 경제성, 기술성, 안전성, 환경친화성의 5가지 기준으로 결정하였으며 세부 평가기준은 군 수송기에 적합하도록 관련 문헌을 참고하여 적용하였다. 의사결정 집단은 현장의 수송기를 운용하고 항공기를 제작하는 현장의 목소리를 가장 잘 대변할 수 있는 전문형 실무자로서의 적합성을 기준으로 하여 5년 이상의 실무경험을 가진 수송기 조종사, 수송장교, KAI의 과장급 실무자로 선정하였다.
