Hotels have recently started to implement enterprise information systems to measure and report sustainability indicators in a smart manner. However, a complex ownership structure in a hotel chain prevents full smart systems adoption at the individual property level. This study explores how a smart sustainability performance measurement system (SPMS) for waste management adoption correlates with customer ratings, customer reviews, operational efficiency scores, and between franchised and corporate-managed properties. We derive insights from the secondary data constructed from multiple sources for a large multinational hotel chain hotel. The findings suggest that hotels that adopt SPMS have better operational efficiency scores and more customer reviews. Within the hotels that adopted SPMS, corporate-managed hotels have a lower level of ratings than franchised hotels, but they have higher operational efficiency scores and more reviews. We discuss research implications for the concept of smart tourism and hotel management literature and managerial implications.

오늘날 기업은 내부 기능 간 협력만으로는 경쟁우위를 달성하기 어려운 실정이다. 또한, 기업이 속한 공급사슬 즉, 공급자와 고객에 이르는 참여자들과 협력하여 공급사슬의 프로세스를 통합하는 것이 중요하다. 이에 따라 본 연구는 중소 벤처기업의 공급사슬 탐색 및 활용전략이 조직역량과 기업운영성과에 미치는 영향력을 밝히는데 목적을 갖고 부산 지역 소재 중소 벤처기업 298개 업체의 중간 관리자를 대상으로 설문조사 방법을 통해 조사하였다. 실증분석 결과 공급사슬 탐색 및 활용전략이 조직역량과 기업 운영성과에 긍정적인 영향을 미쳐 가설은 모두 채택되었다. 그리고 조직역량이 공급사슬 탐색 전략과 활용전략에 따른 기업운영성과의 매개효과에 있어서도 긍정적인 영향을 미쳐 공급사슬 전략으로서의 탐색과 활용이 조직역량의 결집을 통해 기업성과를 높여주는 매개변수로서의 촉진요인임을 확인시켜 주었다. 이 같은 결과는 공급사슬 전략의 탐색과 활용이 조직과 기업 성과를 높이는 촉진 변수로서의 역할과 동시 중소 벤처기업의 공급 사슬 전략이 적극 응용될 필요가 있음을 시사한 것으로 평가할 수 있다.

공급사슬관리에 관한 많은 선행연구들이 지속적으로 공급사슬성과의 향상을 위해서는 협업이 필요하다고 주장하고 있다. 본 연구는 물류기업의 관계특성, 협업, 성과 간의 인과관계를 밝히는 것이며, 특히 관계특성과 성과 간의 관계에서 매개변수로서 두 종류의 협업(운영적 협업과 전략적 협업)에 초점을 맞추고 있다. 분석을 위해 물류기업 164개의 자료가 사용되었으며, PLS를 이용해 구조모형을 분석하였다. 분석결과 신뢰성, 정보공유는 운영적협업에 긍정적인 영향을 미쳤으며, 운영적 협업은 공급사슬 성과에 긍정적인 영향을 미치는 것으로 나타났다. 거래지속의지와 정보공유는 전략적 협업에 긍정적인 영향을 미쳤으나, 전략적 협업은 공급사슬 성과에 긍정적인 영향을 미치지 않는 것으로 나타났다. 따라서 관계 특성과 공급사슬성과 사이에는 운영적 협업이 매개역할을 하는 것으로 나타났다.

Many organizations experience that the Performance they gained from IT portfolio is lower than they expected values. As with any investment, executives are concerned with maximizing the performance from their investment in IT. This study focused on the relationship or fit between orientations of IT strategy and directions of IT portfolio to maximize IT performance. A field survey of chief information officers of Korea manufacturing sector was conducted in 2003. Complete data of 147 firms was analyzed to determine relationship among the three research constructs that are orientations of IT strategy, directions IT portfolio, and IT performance. In this study, the orientations of IT strategy have two dimensions that are operation orientation and market orientation. The directions of IT portfolio have two dimension that are internal system focused and external system focused. And the IT performance has divided into operational performance and competitive performance. As a result of this study, the companies that are putting a focus with operation orientation were concentrated on internal information systems than external information systems. On the other hand, the other companies that are focused on market orientation were concentrated on external information systems than internal information systems. Consequently, the companies that are focused on operation orientation were operational performance higher than competitive performance and the other companies that are focused on market orientation were competitive performance higher than operational performance. More importantly, the research results provide empirical evidence that supports the hypothesis related to closer fit between IT strategy and IT portfolio does lead to increase operational and competitive performance of IT. And the results emphasize manager's efforts of fit between orientations of IT strategy and directions of IT portfolio to be realized IT performance.

This study explores the optimal ensemble size to improve the prediction performance of the Korea Meteorological Administration's operational climate prediction system, global seasonal forecast system version 5 (GloSea5). The GloSea5 produces an ensemble of hindcast data using the stochastic kinetic energy backscattering version2 (SKEB2) and timelagged ensemble. An experiment to increase the hindcast ensemble from 3 to 14 members for four initial dates was performed and the improvement and effect of the prediction performance considering Root Mean Square Error (RMSE), Anomaly Correlation Coefficient (ACC), ensemble spread, and Ratio of Predictable Components (RPC) were evaluated. As the ensemble size increased, the RMSE and ACC prediction performance improved and more significantly in the high variability area. In spread and RPC analysis, the prediction accuracy of the system improved as the ensemble size increased. The closer the initial date, the better the predictive performance. Results show that increasing the ensemble to an appropriate number considering the combination of initial times is efficient.

본 연구의 목적은 코로나19가 국내에 유입되고 확산되는 기간 동안 국내 도소매기업의 성과를 분석하는 것이다. 기업성과에 대한 변수로는 운영효율성 (Operational efficiency)을 선택하였으며, 확률변경분석 (Stochastic frontier analysis)을 통해 운영효율성을 추정하였다. 이후 운영효율성에 미치는 코로나19 기간 (2020년1~2분기)의 효과를 살펴보기 위해 해당 기간의 분기별 고정효과 (Quarterly fixed effect)를 회귀분석을 통해 검토하였다. 본 연구의 주요 결과는 다음과 같다. 첫째, 분석 기간 (2019년 1분기~2020년 2분기) 동안 운영효율성의 평균적 수준은 대략 0.7138이었다. 둘째, 운영효율성에 대한 코로나 19 기간 (2020년 1분기~2분기)의 고정효과는 유의미하지 않았다. 셋째, 운영효율성과 기업규모 사이의 정의 결과를 확인하였다. 한편 본 연구는 운영효율성이라는 기업차원의 성과변수와 코로나19 기간이라는 거시경제적 변수의 관련성을 검토하였다는 점에서 의미가 있다고 볼 수 있다.

Consumer's product selection measures are being shifted from the units' operational performance to overall performance. Low noise, low vibration, and low power consumption rate, etc. which used to be additional quality indices, now become vital performance factors. Especially, noise and vibration characteristics are being considered as equivalent to/or even more critical than operational performance in certain products such as office machines and home entertainment systems, which share the same space with human being's daily life. Therefore, noise reduction and sound quality improvement technology becomes an inevitable design issue for those applications. Qualitative noise characteristics of rotating polygonal disk applied to digital printer systems are presented. Overall sound pressure level change and tonal noise variation with respect to the geometrical properties of polygonal disk, operational speed, and others are briefly discussed based on experimental results.

Recently, IT outsouricng has been one of the major concerns of many companies. This paper explores the relationship between information technology outsourcing risk factors and outsourcing performance. It is based upon a three-phase process utilizing IPO (Input-Process-Output) system. The first phase means the outsourcing planning risks t~at arise from overall environment of outsourcing, organizational refuse, and wrong contracts. The second phase implies outsourcing operational risks, which are occurred while out-sourcing perform and consist of organizational acceptances of outsourcing, partnership and hidden costs. The last phase is outsourcing performance based on four perspective of BSC(Blanced Scored Card). The survey was performed on the IT/IS firms, and the data was collected from 53 service receivers. The result of the analysis are as follows. First, Outsourcing planning risks positively affects the operational risks. Second, Outsourcing operational risks negatively affects the Outsourcing Performance.
