우리나라 여러 항만들에서 활용중인 항만인센티브제도는 경쟁항만과의 가격경쟁력을 높이는 마케팅 도구로 활용되고 있다. 그러나 각 항만은 보다 정밀한 제도의 설계보다는 경쟁항만의 제도에 대한 즉각적이며 단편적인 모방대응전략을 주로 사용하고 있다. 또한 고객 화물 집단별예산도 이론적 검증 없이 배분되었기 때문에 제도의 효과에 대한 정밀한 분석과 제도의 재설계가 요구되고 있다. 본 연구는 선형계획모형으로 항만인센티브제도를 모형화하고, 광양항을 대상으로 사례분석 하였다. 광양항에 대한 분석결과 기존의 정성적인 방식의 인센티브제도 설계만으로는 이론적으로 미흡한 것으로 분석되었으며, 각 유형 마다 인센티브의 효과 유무 또는 과부족 여부도 확인되었다. 인센티브제도의 전체 예산중 마일리지 예산은 최소화하고 기존화물 집단예산에 61.77%, 그리고 신규(증가)화물 집단예산에 38.23%씩 배분하는 것이 더욱 합리적인 것으로 나타났다. 추후연구에서는 본 연구과정에서 제기된 정확한 모형 구축에 필요한 충분한 기초자료에 대한 접근과 인센티브 제도를 더욱 정확하게 파악할 수 있는 제약조건 등이 대한 보완되어야만 할 것이다.

Reverse logistics network design issues have been popularly discussed in recent years. However, few papers in the past literature have been dedicated to incentive effect on return quantity of used products. The purpose of this study is to formulate a dynamic nonlinear programming model of reverse logistics network design with the aim of managing the used products allocation by coordinating the collection centers and recovery facilities to warrant economic efficiency. In the optimization model, a fuzzy approach is applied to interpret the relationship between the rate of return and the suggested incentives. Due to funding constraints in setting up the collection centers, this work considers these centers as multi-capacity levels, which can be opened or closed at different periods. In view of the fact that the problem is known as NP-hard, we propose a heuristic method based on tabu search procedure to solve the presented model. Finally, several dominance properties of optimal solutions are demonstrated in comparison with the results of a state-of-the-art commercial solver.

Pay-for-performance plans are some of widely used human resource practices in many firms, including shipbuilding, for productivity and motivational improvement purposes. Such plans play an important role in industries that are highly labor-intensive, and where effective management of human resources is critical to business operations, such as the shipbuilding industry. Those practices can have large impact on employee performance and ultimately company competitiveness. Research studies that show how such incentive plans improve productivity and reported pattern of adoption by firms have spurred the use and adoption in many firms. However, there are also researchers who point out that there are negative consequences to using incentive plans. Therefore it is important for companies to carefully consider the practices they use. In this paper, I discuss research findings that support the practices and critical viewpoints related to pay-for-performance plans. Research findings from Korean literature are, then, discussed. The shipbuilding industry is chosen because proper human resource management is critical in reducing turnover and increasing employee satisfaction. Through a shipbuilding company case, problems related to using pay-for-performance incentive plans and how they affect work-related issues of employee morale, cooperation, and teamwork will be discussed. While positive aspects have been emphasized to drive greater adoption among firms, the resulting consequences of the pay plans need to be seriously considered and improvements upon the plans made by firms. Improvement suggestions are discussed in the conclusions and implications.

Immediate responsibilities for occupational health and safety (OHS) management reside in business proprietors and supervisors whose voluntary participation in OHS educational programs, not legal sanctions, may thus lead to safe and pleasant work environments. This study investigates how to promote the effectiveness of OHS educational programs to draw voluntary participations in such programs in Korea To this end, drawbacks of current practices in OHS education are first analyzed, and then OHS related policies in advanced countries in the area of disaster prevention such as United States and Germany, are also scrutinized. Based on the preliminary investigations, the following propositions are made to lay out the foundation for promoting effective OHS educational programs in Korea: improvement of government regulations, revitalizing job training initiatives, on-site OHS education, compensation and incentive programs for OHS education. These propositions may also facilitate the deployment of disaster prevention activities across the organization and prevent various occupational disorders (for example, musculoskeletal disorders). This study emphasizes that monolithic OHS education systems led by regulatory agencies may not be efficient to ensure healthy and safe work environments. Globally competitive OHS educational systems may be established only when they are based on the health and safety requirements specified by proprietors and workers.

Background: Incentive and penalty (I/P) programs are commonly used to increase employees' safety outcomes, but its influence on employees' safety outcomes is under-investigated. Moreover, under developed economies lack safety culture and there is dearth of literature focusing on empirical studies over there [1]. Based on these gaps, this study attempts to see the impact of I/P programs on safety outcomes in a developing country. Methods: The study was carried out in three stages, where Stage I revealed that selected 45 organizations were deficit of safety culture and practices, while only three firms were found good at safety practices. At Stage II, these three firms were divided in two clusters (groups), and were probed further at Stage III. At this stage group, one was manipulated by providing incentives (experimental group) and employees' responses in terms of safety motivation and performance were noticed. Results: It was observed that the experimental group's safety motivation and performance had improved (both for immediate and 1-month later performance). The results were further probed at Phase 3 (after 3 months), where it was found that the benefits of I/P programs were not long lasting and started replenishing. Conclusion: Findings of the study helped researchers conclude that safety incentives have only short-term influence on safety outcomes, while a long-term and permanent solution should be found.

인터넷 상에서의 비디오 스트리밍을 위한 대안으로서 P2P(Peer-to-Peer)가 관심을 받고 있다. P2P 시스템은 피어들의 대역폭 기여에 의존하고 있지만, 피어들은 자신의 대역폭을 제공하는 것을 꺼리는 경향이 있다. 본 논문에서 우리는 상향 대역폭 기여를 촉진하는 P2P 스트리밍 시스템을 제안한다. 제안 시스템에서 피어들 간의 공평성을 유지하고, 제어 가능한 방법으로 협력적인 피어와 이기적인 피어에게 다른 품질의 비디오를 제공한다. 제안 시스템은 기여한 상향 대역폭에 기초한 평가 기법으로 피어가 협력적인지 이기적인지를 결정하고, 협력적인 피어들에게는 인센티브로서 고품질의 비디오를 제공한다. 또한 제안시스템이 효과적으로 동작할 수 있도록 트리 재건조 알고리즘을 제안한다. 시뮬레이션을 통해, 트리 재건조 알고리즘이 효과적으로 동작하며, 인센티브 기법이 협력적인 피어에게 더 많은 하향 대역폭을 할당하고 이기적인 피어에게는 저품질 비디오를 제공함을 보인다.

Following the increasing importance of logistics function in today's company operation, this work explores the mechanism for cooperation within a supply chain, especially between a firm and an independent logistics supplier. We first characterize the optimal linear logistics contract based upon the recent developments in contract theory, and then investigate the effect of such a contract on the firm's inventory policy. The results indicate that the order quantity becomes smaller and the lead time becomes shorter and under the optimal contract than without the incentive scheme. Accordingly, the service level under the optimal contract becomes higher. These findings are in accordance with the literature on vertical control and JIT (Just in Time) philosophy.

This study presents an exploratory investigation of SMEs in Vietnam to understand the impact of personal-level factors on middle managers' work motivation and the moderating role of work environment. A survey of 450 middle managers (MMs) in 150 Hanoi's SMEs was conducted. The findings of this research showed a significant positive impact of Achievement (ACHV), Recognition (RECOG), and Responsibility (RESP) on work motivation of MMs under the investigation. Furthermore, the result indicated that the work environment affects the relationship between personal-level factors and work motivation of participants. Consequently, both work environment improvement and strategies related to personal-level factors need to be taken into consideration. Especially, Recognition and transparency in Responsibility are appreciated in organizations with a low level of work environment satisfaction. However, there were no indications that Participation (PAR) and Communication (CMM) have a considerable impact on work motivation of respondents, being neither low level nor high level of work environment satisfaction. Based on the findings, recommendations are suggested for Vietnam's SMEs to improve work motivation of MMs, by (i) developing standards with emphasis on their achievement, (ii) paying attention to organizational culture focusing on the responsibility of this managerial level, and (iii) building an adequate incentive system, especially non-financial incentives.

This study empirically examines the correlation between the data, system, service quality, collective intelligence, innovation activity, and work performance of the KMS for employees of state-run enterprises. This study also confirmed that collective intelligence and innovation activity have a mediating effect on the relationship between KMS system quality and work performance. For this study, employees of state-run enterprises completed a 5-point Likert scale survey, and the data obtained were analyzed with descriptive statistics. The reliability and validity of variables were also verified through a measurement model analysis. Structural equation modeling of IBM SPSS 26 and AMOS 26 were used to prove the hypothesis. Through this study, For the improvement of sustainable work performance of state-run enterprises, which is a difficult issue to solve, not only should the quality of the KMS utilized in the enterprises be improved and managed, but also the design for various incentive schemes tailored to the enterprises' job characteristics, such as rewards, HR bonus, work incentives, job allowance, and encouragement from the head of the enterprise, should be reviewed and continuously developed in reflection of the active collective intelligence of the employees and the effect of innovation activities. Then, the work performance of public institutions will increase.
