Improve of productivity is a key for the development of a company, which can be pursued in the apect of material factor and personal factor. And the motives of worker for their job is more influenced by the chance of incentive compensation or self-development than by participation in management and safety of their post ect. Contingency theory is one of the theories that cope with this study Therfore, this study describes incentive compensation for satisfying worker desire related company's productivity, and be presented to the aspect of contingency accounting.

This paper introduces some of the developments related to the handling equipment in container terminals and various new conceptual handling systems that have been proposed during the last several decades. The basic ideas behind the previous equipment improvements are analyzed to identify future directions that can be used for devising new handling systems. The handling systems in the container terminals include a quayside handling system, transport system, and yard system. In response to the deployment of mega-sized vessels for container transportation systems, productivity improvement has become one of the most urgent issues in the container terminals. This paper analyzes the previous improvements made for achieving higher productivity in the three subsystems of container handling. Some conceptual handling systems are introduced including the linear motor conveyance system (LMCS), automated storage and retrieval systems (AR/RS), overhead grid rail (GRAIL), SPEEDPORT, SuperDock, the automated container system by ZPMC (ACS-ZPMC), and AUTOCON.

The testing processes for VLSI finished devices are considerably complex because they require different types of ATE to be linked together. Due to the interaction effect between two or more linked ATEs, it is difficult to trace down the cause of the unexpected longer ATE setup time and random yields, which frequently occur in the VLSI circuit-testing laboratory. The goal of this paper is to develop and demonstrate the methodology designed to eliminate the possible interaction factors that might affect the random yields and/or unexpected longer setup time as well as increase the productivity. The statistical method such as design of experiment or multivariate analysis cannot be applied to the final testing floor here directly due to the environmental constraints. Expanded product data information (PDI) is constructed by combining product data information and ATE control information. An architecture utilizing expanded PDI is designed, which enables the engineer to conduct statistical approach investigation and reduce the setup time, as well as increase yield.

The traditional crop productivity simulations based on crop models are normally site-specific. To simulate regional crop productivity, the spatial crop model is developed in this study by integrating Geographical Information System (GIS) with Erosion Productivity Impact Calculator (EPIC) model. The integration applied a loose coupling approach. Data are exchanged using ASCII or binary data format between GIS and EPIC model without a common user interface. The spatial EPIC model is conducted to simulate the average corn and wheat productivity of 1980s in North China. The results show that the simulation accuracy of the spatial EPIC model is acceptable. The simulation accuracy can be improved by using the detailed crop management information, such as irrigation, fertilizer and tillage schedule.

세계화가 빠르게 진전되면서 한국 기업들의 오프쇼어링 비중도 커지고 있다. 기존 연구들의 경우 오프쇼어링의 효과보다는 기업이 오프쇼어링을 선택하는 결정요인을 분석하는데 집중하고 있다. 따라서 본 논문은 오프쇼어링이 한국 기업의 생산성에 미친 영향에 대해 정량적으로 분석했다. 이를 위해 통계청의 기업활동조사를 기반으로 기업수준의 패널데이터를 이용해 합동 최소자승법과 고정효과 패널모형을 통해 분석했다. 기존 연구와는 달리 서비스업을 제조업과 구분하여 오프쇼어링의 영향을 추정하였으며, 두 산업 간의 결과를 비교하였다. 합동 최소자승법 결과에서는 전체 기업의 오프쇼어링 비중이 1% 증가할 때 노동생산성은 0.03% 증가하는 것으로 분석되었다. 그러나 고정효과 패널모형 결과의 경우, 오프쇼어링이 기업의 노동생산성에 주는 효과가 유의하게 추정되지 못했다. 모든 모형에서 오프쇼어링이 제조업 생산성에 긍정적 영향을 미치는 것으로 추정되었다. 서비스산업의 경우 고정효과 패널분석 결과에서 오프쇼어링이 생산성에 미치는 영향이 부정적으로 추정되었으나 유의하지는 않았다. 자본과 R&D비용 등 기업의 생산성에 영향을 주는 다른 설명변수들은 서울에 본사가 있는가 여부에 대한 더미변수를 제외하고 대부분 생산성 향상에 기여한다는 결과를 얻었다.

The competitiveness of the service sector is driven by its productivity. Services innovation is essential to enhancing service productivity. This paper first presents a framework for services innovation. The framework consists of three main phases of a service lifecycle (namely, service development, service operation, and service improvement), which are supported by IT infrastructure and service R&D management functions. This paper then identifies major research issues that should be investigated in the near future. The current issues of three representative service industries (namely, healthcare service, telecommunications service, and financial service) are also discussed.

The external R&D, which includes the adoption of the external technology and knowledge in addition to the internal R&D, is one of important factors for the innovation. Especially for small and medium-sized enterprises (SMEs), the external R&D has been considered as a key factor to carry out the innovation more efficiently due to the limitations of their resources and capacities. However, most of extant studies related to external R&D have focused on analyzing the influence of external R&D on innovation outputs or outcomes. Only a few studies have explored the impact of external R&D on the innovation efficiency. This study therefore investigates whether the external R&D effects the industry's innovation efficiency and productivity. On this study, we used Korean manufacturing industry data of SMEs from 2012 to 2014 and employed a global Malmquist productivity analysis technique, which is based on the Data Envelopment Analysis (DEA), to assess the innovation efficiency and productivity. Innovation performances of external R&D group and internal R&D group are compared. Then, the sectoral patterns of both innovation efficiency and productivity are analyzed with respect to the technological intensity, which is introduced by OECD. The results show that the gap of innovation efficiency between external and internal R&D groups has gradually decreased because of the continuous improvement of the external R&D group's performance, while the external R&D group lag behind the internal R&D group. In addition, patterns of the innovation efficiency and productivity change were different depending on the technological intensity, which means that the higher the technological intensity, the greater the effect of external R&D.

Environmental conditions are important in increasing the fruit sugar content and productivity of the new cultivar Autumn Sense of Actinidia arguta. We analyzed various soil properties at experimental sites in South Korea. A Pearson's correlation analysis was performed between the soil properties and sugar content or productivity of Autumn Sense. Further, a decision tree was used to determine the optimal soil conditions. The difference in the fruit size, sugar content, and productivity of Autumn Sense across sites was significant, confirming the effects of soil properties. The decision tree analysis showed that a soil C/N ratio of over 11.49 predicted a sugar content of more than 7°Bx at harvest time, and soil electrical capacity below 131.83 µS/cm predicted productivity more than 50 kg/vine at harvest time. Our results present the soil conditions required to increase the sugar content or productivity of Autumn Sense, a new A. arguta cultivar in South Korea.
