외식업체에서 비용의 가장 많은 부분을 차지하는 것이 인건비이다. 따라서 종업원 스케쥴링은 비용절감을 위한 중요한 요소이다. 그러나 스케쥴링은 여러 가지 요구 조건들을 만족시켜야 하므로 복잡하고 많은 시간과 노력이 소요되는 비생산적인 업무이다. 본 연구의 목적은 수리계획법을 이용하여 스케쥴링 업무에 드는 시간과 비용을 절감하고 인력을 효율적으로 관리하는 방안을 모색하는 것이다. 이러한 연구목적을 위해 본 연구에서는 사례기업을 대상으로 수리계획법의 현실 적용효과와 문제점을 확인하였다.

Walking behaviors are one of the most basic transport modes in daily life. As a result, the efforts and concerns on pedestrians are consistently increased. This study tried to reveal significant factors for pedestrian volumes through structural equation models and compare the impacts of the whole time of day, off-peak time, peak time on the pedestrian volumes. The results of the analysis show that commercial business factors, accessibility factors, walking environment factors are the most significant factors that increase pedestrian volumes. Whereas, housing factors do not contribute to increase the pedestrian volumes. In the non-peak time, the weight of commercial business factors is higher than the whole time of day, while the weight housing factors, accessibility factors, walking environment factors are lower. In the peak time, however, the weight of commercial business factors decreases rather than the whole time of day, while the weight of the other factors increase.

The objective of this study is to verify effects of employees' cognition of their job characteristics in production department of manufacturing companies on production performance and also to verify the moderating effect of the characteristics of managerial accounting information in the relationship between job characteristics and productivity. To achieve this purpose, this study divides the factors of job characteristics into task diversity, task significance, autonomy, and task identity and production performance into flexibility, time, and quality. The results of this study are as follows. First, There is a significant relationship between job characteristics and production performance according to employees' cognition of their job characteristics. Second, There is a significant relationship between job characteristics and production performance according to the characteristics of managerial accounting information.

With a wide spread of smart phone, Smart society has been progressed through nationwide that changed way of personal daily life rapidly. As smart work has been introduced and utilized at the office, it is possible that the person in charge can handle remote transaction without restriction of time and place. Smartlization throughout the society has been progressed, member of work and system related can be linked mutually and took personalized services. This study identifies explorative moderating effect of smart environment at performance of work with employee cognition. As a result, found that smart work environment with complexity of work has increased moderating effect over collaborative work.

This study tried to analyzed the relationship outcome and commitment in order to suggest to a outcome for commitment decision-making of e-trade. 6 hypothesis were constructed for analysis based on previous literature review. The subject of this study is to analyse on electronic trade practice outcome on the international trade practice commitment. This paper investigates the outcome determinants of e-trade commitment. There are 250 sended samples and 188 returns, 168 of them are analyzed on commitment for a electronic trade outcome. The first, multiple regression result shows that the international trade practice outcome are positively affected by the "Overseas market research commitment", "e-L/C Practice commitment", "Clearance Practice commitment", "e-B/L or global logistic commitment", "Payment or e-Nego commitment". However, The "Commerce practice commitment" factors does not affect in the electronic trade practice outcome.

As a smart mobile device is gaining popularity as a tool to utilize internet services, the demand on the cloud service (which eliminates the spatial and/or temporal restrictions in enjoying the services) is increasing. This trend also has an effect on the style of performing business tasks so that the concept of 'smart-work' (e.g. doing business tasks in anywhere and anytime) is being spread over the industries. The facilities for the smart-work is, however, focused on providing the tools designed to supporting business tasks such as co-working in writing documents, video conference, searching data via smart (mobile) devices neglecting the industries' needs for the infrastructure by which they can create their own business applications and mobile cloud services at a low (or moderate) price. The paper proposes a mobile cloud service platform, which provides an SDK for developing business applications and offers the applications to smart mobile devices as a PaaS (Platform as a Service).

The relative importance of leisure trip has been increased after adopting the five-day workweek system and considering the higher income level. Thus, the value of travel time for intercity leisure trips should be estimated to conduct a reasonable benefit/cost analysis for railway construction projects. In this paper, the value of travel time was estimated separately for each trip purpose such as business, leisure, and other non-business than leisure. The estimated values of leisure travel time ranged from 5,310 to 14,185 (won/hr) by altering travel mode, and were increased by 42-107% when comparing with those of non-business travel time. Besides, how to apply the value of intercity leisure travel time for B/C analysis of railway projects was suggested. For the construction case of a railway connecting Chuncheon and Sokcho, the estimated benefit was increased by 2.3%.
