  • 2016년 통계청의 자료에 따르면 법인의 직무발명 비중이 늘어나고 있음에도 불구하고, 정당한 직무발명보상을 실시하지 않는 기업은 56.9%나 되는 것으로 집계되었다. 하나의 원인은 객관적인 특허 기여율 산출 방식과 정당한 보상의 명확한 기준이 정립되지 못했기 때문이다. 본 연구에서는 정당한 직무발명 보상금 산정을 위해 DCF (Discounted cash flow)와 AHP (Analytical hiearchy process) 방법론을 활용한 새로운 특허 기여율 산출 방식을 제시하고 이를 활용하여 실제 사례를 통해 검증하였다. 그 결과 기존 판례의 보상금 산정보다 2.3배 높은 금액이 산정되었으며 이는 정당한 보상금 산정에 있어 명확한 기준이 정립되지 않아 발명자 보호에 매우 미흡한 현 상황에서 조금 더 발명자를 보호할 수 있는 객관적인 보상금 산정 기준을 제시하고 있다는 점에서 의의가 있다. 본 방법론은 계산방법과 절차가 단순하여 중소기업을 위한 직무발명 보상 기법으로 활용 가능할 것으로 기대한다.

  • To provide a guaranteed Quality of Service (QoS) to real-time traffic in High-Speed Downlink Packet Access (HSDPA) core network, we proposed an enhanced mechanism. For an enhanced QoS, a Class-Based Low Latency Fair Queueing (CBLLFQ) packet scheduling algorithm is introduced in this work. Packet classification, metering, queuing, and scheduling using differentiated services (DiffServ) environment was the points in focus. To classify different types of real-time voice and multimedia traffic, the QoS provisioning mechanisms use different DiffServ code points (DSCP).The proposed algorithm is based on traffic classes which efficiently require the guarantee of services and specified level of fairness. In CBLLFQ, a mapping criterion and an efficient queuing mechanism for voice, video and other traffic in separate queues are used. It is proved, that the algorithm enhances the throughput and fairness along with a reduction in the delay and packet loss factors for smooth and worst traffic conditions. The results calculated through simulation show that the proposed calculations meet the QoS prerequisites efficiently.

  • Recently, controversy over intellectual property rights for protecting genetic resources and traditional knowledge has been emerging. Very active debates and global discussions are being carried out in various international organizations for possible approaches to be taken for these properties, and for the fair and equal sharing of the benefits from these intellectual properties. There is a need to evaluate adopting a sui generis system which is being pushed by developing nations, or adopting a policy which will guaranteee benefit sharing such as sharing royalties from marketing final products, technical transfers, capacity building, and participating in research activities. Also, it is very important to examine the legal issues concerning genetic resources based on Convention on Biological Diversity for the fair and equal sharing of the benefits with developing nations, at the same time assuring developed nations of access to genetic resources.

  • Purpose - Consumers heuristically have a specific stereotype on the price level of individual retail format because each format provides them with a different level of purchase satisfaction and emotional benefits. However, if price image which is consumers' overall impression of the aggregate price level of a retailer does not match with their expectations, its price level would be perceived as unfair. It will eventually lead to dissatisfaction and decreased revisit intention. Focused on department store and discount store, this study was designed to verify whether the price fairness plays a role of mediating effect on two influential relationships between price image and post-purchase satisfaction, and price image and repatronage intention. Research design, data, and methodology - A main survey was conducted to 140 students and 128 effective responses were used for the related analysis. T-test, factor analysis, reliability test, and mediated regression analysis were performed. Six hypotheses were developed to examine the mediating effect of price fairness on the two influential relationships between price image and post-purchase satisfaction, and price image and repatronage intention. It was also examined whether the price image of two different retail format is formed differently or not. Results - People perceived the price images of the two retail formats differently. Overall price level of department store is much higher than that of discount store. Analysis results showed that price image did not solely have a significant influence on post-purchase satisfaction unless price fairness as a mediating variable is added. Price fairness turned out to be having a significant influence on relationship between price image and repatronage intention. It influences on repatronage intention directly and also via price fairness. Conclusions - Post-purchase satisfaction can be achieved only if people perceive the price image as fair no matter how the price level is high or low according to traits of retail formats. If they think it's not fair, they would disapprove of the rightness for the price image, and also express their dissatisfaction with it. Consumers willingly make repeated visits to a store if they are convinced of appropriate price level which is perceived as fair, and if they experienced a satisfaction with overall benefits a particular store offered.

  • The National Science Fairs has been held in every year for the promotion of science and technology and scientific civil life. The purpose of this study is to survey the current problems in National Science Fairs by making up a question and to improve them. The study makes up a questionnaires about the existing Science Fairs to the teachers who have submitted their works to the Science Fairs and suggest the ways of improvement. The result of questionnaires is that little availability of reference materials, difficulty of paying proper attention to regular classes because of frequent travels, and absence of experimental devices and experimental rooms are perceived as major obstacles in preparing for the exhibition. Respondents teacher also pointed out some problems with the current organization of the exhibition; non-voluntary selection process for the potential authors, separation of research content from regular teaching materials, unrealistically high standard, low participation rate of teachers, so many exhibited works, lack of professionalism in the screening process. The majority however, agreed that the exhibition event should be continuously done, after remedial measures have been taken about the problems. First, the side of science education is emphasized in a purpose of the science fairs to let activity related to science fair be closely connected with school education. Second, students have to be divided according to grade. Third, research level have to be set not too higher than regular instruction content. Fourth, hand book related to science fairs have to be manufactured and spread. Fifth, data of local science fair have to be arranged. Sixth, judging section have to be subdivided and people related to science education have to be included to a judge. Seventh, excellent works have to be support to participate in ISEF.

  • A simple scheduler satisfying the proportional fairness (PF) was introduced in wireless access networks and revealed that it can achieve a good compromise between total throughput and user fairness. Though it has received much attention for some time, its application was mainly restricted to the single channel systems. In this paper, we study how to implement the PF scheduler in the multi-channel environments such as OFDMA/TDMA. Besides the traditional PF-SC scheme, we propose a new PF-OPT scheme that is the genuine PF scheduler in a sense of maximizing the total log-utility of users. The simulation results show that PF-OPT gives large throughput under the heterogeneous subchannel statistics.

  • The purposes of this study were to examine the motivation of career choice for chefs in luxury hotels through IPA analysis based on the differences between importance and satisfaction, and to investigate the impact of motivations of career choice on job satisfaction. The results are as follows. First, "matched aptitude" and "interest in cook" were found as factors of importance and satisfaction. Second, sufficient reward should be provided through incentive, increasing salary, and promotion. Third, the system of internship and temporary employee should be revised, and the motivation should be provided through performance-based reward and incentive system. Fourth, fair personal evaluation, transparent promotion system, fair reward system should be required to increase job satisfaction. Fifth, internal environment is important rather than social reputation or popularity for those who consider chefs as future career.

  • WFQ(Weighted Fair Queuing)은 지연이나 공평성의 특성에 있어서 이상적인 트래픽 스케줄링 알고리즘으로 간주되었다. N세션에 서비스를 제공하는 WFQ 스케줄러의 스케줄링 연산은 각 패킷 전송 시간당 O(n)의 계산 복잡도를 가지며, 구현 또한 복잡하다. Self-Clocked Fair Queuing과 같은 WFQ 알고리즘의 구현을 간단히 하고자 하는 노력은 지연범위나 특성에 영향을 주게 되어 다양한 트래픽이 제공되는 경우 각 트래픽의 공평성을 지원해주지 못한다. 그러므로 지연이나 지연 변이 측면에서 공평성을 지원하고 구현상의 계산 복잡도를 줄인 스케줄링 알고리즘이 필요하게 되었다. ATM 다중화기의 셀 스케줄링 알고리즘 역시, ATM의 특성상 다양한 특성의 서비스를 제공하기 위해서, 다양한 특성의 트래픽에 대한 공평성을 제공하는 새로운 알고리즘의 연구가 필요하다. 이 논문에서는 ATM 스위치 내의 다중화기에서 사용되는 새로운 셀 스케줄링 알고리즘을 제안하고 실험을 통해 이 알고리즘의 성능을 검증하고자 한다. 이 알고리즘은 여러 개의 우선 순위 큐를 갖고, 각 우선순위 큐마다 스케줄링 연산이 O(1)의 계산 복잡도를 갖는 Parallel Priority Queuing 알고리즘이다.
