This paper seeks to find out possibility of introducing market order into Korean fisheries regulatory system. Hayek tells us that market order is equivalent to spontaneous order, while regulations are man-made order created based on incomplete knowledge. He also sees market competition as a discovery procedure of knowledge and information. From this perspective is discussed Korean fisheries regulatory reform-particularly issues of establishing property right on fishery resources. It appears that there is quite a large room for substituting market functions for the regulations regarding fishery resources management, even though fishery resources have a very nature of common pool. Advanced fisheries suggest that successful regulatory reform require a well-prepared strategic plan and check list. In addition, the government should be able to secure sufficient monitoring and surveillance power and to play an important role as a fair supervisor.

Effective Training has been recognized as one of the most important success factors for enterprise resource planning (ERP) system operations. However, both ERP system vendors and user companies have failed to provide an effective training method for users because practical business process cases cannot be formalized. Also, incomplete testing by ERP system vendors results in insufficient and ineffective user training. This paper suggests a scenario framework for ERP testing and training (SF-ETT). SF-ETT is constructed by expanding the practice-based ERP testing scenario construction framework designed for uniERPII. SF-ETT contains concrete business process entities that users understand actually and provides practice definition, notation, and architecture.

전산 코-드인 LATREP, HWRAXAV 및 CITATION을 이용하여 CANDU-PHWR인 월성 1호기의 핵설계 특성 해석을 시도하였다. 계산된 주요 핵 특성은 CANDU 핵 연료봉 집합체에 대한 격자상수와 로심내의 출력 분포이며 그 계산 결과는 월성 1호기의 예비 안전성 보고시와 비교되었다. 계산치와 예비안전성 보고서에 제시된 설계치 사이의 차이점에 관해서는 예비안전성 보고서의 로심 기술에 대한 불완전한 자료와 계산 방법이 서로 다르다는 관점에서 검토되었다.

The purpose of this study is to identify the effects of college students' relationship status on their clothing behavior and purchasing process. The subjects of this study were college students. After a survey, 113 questionnaires were used for the data analysis excluding incomplete ones. Factor analysis, paired t-test, Pearson's correlation, one-way ANOVA, MANOVA and Chi-square test were conducted. The data analysis found that female students had higher levels of clothing interest, and fashion-seeking, impulse buying and individuality-seeking motives than male students. Female students who had boyfriends showed particularly higher levels of fashion-seeking and impulse-buying motives. Throughout the clothing purchase process stages, students were most influenced by girlfriend/boyfriend, especially in the evaluation stage. Students who had girlfriends/boyfriends were significantly more influenced by them. Female students were more influenced by parents at the evaluation stage and their female friends at the information search stage.

Monitoring and analyzing people in video images are important and attract attention from many researchers in computer vision field. In this paper, we propose a new technique by which people overlapped one another in an image can be extracted and counted. After extracting moving people from video images as foreground, their heads are searched by Hough Transform inside the foreground. Since heads are comparatively stable in spite of motion in video images, semicircles along the head tops can be important features to be found in an edge map. In our experiment, the technique successfully separated people who existed at the same vertical positions, which was Impossible by existing techniques. Meanwhile, it showed high dependency on edge information and false results were obtained when the rather were rather incomplete.

The control of deterioration processes for which only incomplete state information is available is examined in this study. When the deterioration is governed by a Markov process, such processes are known as Partially Observable Markov Decision Processes (POMDP) which eliminate the assumption that the state or level of deterioration of the system is known exactly. This research investigates a two state partially observable Markov chain in which only deterioration can occur and for which the only actions possible are to replace or to leave alone. The goal of this research is to develop a new jump algorithm which has the potential for solving system problems dealing with continuous state space Markov chains.

The maximum weight of single stock in mutual fund is limited by regulations to enforce diversification. Under incomplete information with added constraints on portfolio weights, enhanced performance had been reported in previous researches. We analyze a weight vector to examine the effects of additional constraints on the portfolio's performance by computing the Euclidean distance from the in-sample tangency portfolio, as opposed to previous researches which analyzed ex-post return only. Empirical experiment was performed on Mean-variance and Minimum-variance model with Fama French's 30 industry portfolio and 10 industry portfolio for the last 1,000 months from August 1932 to November 2015. We find that diversification-constrained portfolios have 7% to 26% smaller Euclidean distances with the benchmark portfolio compared to those of unconstrained portfolios and 3% to 11% greater Sharpe Ratio.

An algorithm is suggested that truncted projection among the incomplete projections can be recovered from non-iterative extrapolation matrix by band-limited function. After the image being reconstructed from the recovered signals by non-iterative extrapolation, a known controur information and reprojection algorithm are used. It is shown that the reconstructed image using these algorithms is close to the original image. The effectiveness for these algorithms is proved by computer simulation.

분산시스템에서 부하균형을 유지하기 위해서는 네트워크상의 각 노드는 다른 노드들의 부하상태정보를 가져야만 한다. 네트워크상에 ν개의 노드가 존재할 때 모든 노드간에 부하상태정보를 교환하기 위해서는 Ο(ν²)의 트래픽 오버헤드가 필요하게 된다. 이 논문에서는 분산된 노드간에 동기적으로 동작하는 부하균형 알고리즘을 제시한다. 이를 위해 먼저 SBIBD(symmetric balanced incomplete block design)에 근거하여 (ν,k,1)-configuration에 의해 ν=k²-k＋1개의 노드를 갖는 네트워크 토폴로지를 구성하였다. 이 망에서 동작하도록 고안된 부하상태정보 전파 알고리즘은 (equation omitted)의 메시지 오버헤드를 가지면서 각각의 노드가 ν개의 모든 노드에 대한 부하상태정보를 가지도록 한다. 또한 이 부하균형 알고리즘은 모든 링크가 부하상태정보 전송을 위해 동일한 트래픽을 갖도록 설계되었다.

There are various ways in classification methodologies of data mining such as neural networks but the result should be explicit and understandable and the classification rules be short and clear. Rough set theory is a effective technique in extracting knowledge from incomplete and inconsistent information and makes an offer classification and approximation by various attributes with effect. This paper discusses granularity of knowledge for reasoning of uncertain concepts by using generalized rough set approximations based on hierarchical granulation structure and uses hierarchical classification methodology that is more effective technique for classification by applying core to upper level. The consistency rules with minimal attributes is discovered and applied to classifying real data.
