WTO system has just begun and the development for fishing industry is being carried out. The task of National Federation of Fisheries Cooperatives(NFFC ) is not only to support producers' competitive edge, but also to realize the efficiency embodied in the businesses of NFFC itself. Then it can continue to compete other firms and offer the comprehensive services only when it achieves its efficiency. The efficiency of NFFC is the economies of scale and scope. NFFC should achieve its scale and scope economies to be efficient. NFFC needs to expand its size in fish distribution and banking business to have scale economies. Also, the communication and coordination systems among member-supporting, fish distribution, and banking business need to be strengthened to get its scope economies. It is interesting theoretically and in policy making to test the hypotheses that cooperatives are capable of offering the comprehensive services such as distribution, credit, and insurance to the members. It is meaningful to their development for agricultural and small businesses cooperatives as well as fisheries cooperatives to survive the fierce competition under WTO system. National Federation of Agricultural Cooperatives(NFAC) is much greater in business size than NFFC. The estimation and test in the multiproduct cost function of NFAC will show interesting results.

For navigation of a service robot, mapping and localization are very important. To estimate the robot pose, the map of the environment is required and it can be built by exploration or SLAM. Exploration is the fundamental task of guiding a robot autonomously during mapping such that it covers the entire environment with its sensors. In this paper, an efficient exploration scheme based on the position probability of the end nodes of a topological map is proposed. In this scheme, a topological map is constructed in real time using the thinning-based approach. The robot then updates the position probability of each end node maintaining its position at the current location based on the Bayesian update rule using the range data. From this probability, the robot can determine whether or not it needs to visit the specific end node to examine the environment around this node. Various experiments show that the proposed exploration scheme can perform exploration more efficiently than other schemes in that, in most cases, exploration for the entire environment can be completed without directly visiting everywhere in the environment.

Human detection is a challenging task in many fields because it is difficult to detect humans due to their variable appearance and posture. Furthermore, it is also hard to track the detected human because of their dynamic and unpredictable behavior. The evaluation speed of method is also important as well as its accuracy. In this paper, we propose unified detection and tracking method for humans using Gaussian-PSO (Gaussian Particle Swarm Optimization) with the HOG (Histograms of Oriented Gradients) features to achieve a fast and accurate performance. Keeping the robustness of HOG features on human detection, we raise the process speed in detection and tracking so that it can be used for real-time applications. These advantages are given by a simple process which needs just one linear-SVM classifier with HOG features and Gaussian-PSO procedure for the both of detection and tracking.

This paper proposes a system architecture for USN with a service robot to provide more active assisted living services for elderly persons by monitoring their mental and physical well-being with USN environments at home, hospital, or silver town. Sensors embedded in USN are used to detect preventive measures for chronic disease. Logged data are transferred to main controller of a service robot via wireless channel in which the analysis of data is performed. For the purpose of handling emergency situations, it needs real-time processing on gathering variety sensor data, routing algorithms for sensor nodes to a moving sink node and processing of logged data. This paper realized multi-hop sensor network to detect user movements with biometric data transmission and performed algorithms on Xenomai, a real-time embedded Linux. To leverage active sensing, a mobile robot is used of which task was implemented with a priority to process urgent data came from the sink-node. This software architecture is anticipated to integrate sensing, communication and computing with real-time manner. In order to verify the usefulness of a proposed system, the performance of data transferring and processing on a real-time OS with non real-time OS is also evaluated.

In a divorced family, child-centered custody evaluation is essential to ensure the child's best interests and healthy adaptation. A mental health professional's role and involvement are required in gaining an in-depth understanding of various environments and dynamics surrounding the child and family. Domestic violence, including child abuse and intimate partner violence (IPV) or parental alienation syndrome (PAS), is often observed in cases of custody evaluation in high-conflict divorced families, sometimes accompanied by allegations. Such cases warrant an extremely careful approach by the evaluator, who needs to be competent in interpreting the familial dynamics based on a reasonable context understanding. Genuine professionalism is a must for a custody evaluator to best help the child and carry out a high-quality custody evaluation process, and evaluators need to be ready for this task through adequate preparation and empowerment. This article is devoted to examining custody evaluation in divorced families in cases of IPV, child abuse, and PAS.

R In today's competitive and global business management, Concern of an enterprise is to strengthen the core competency and improve it's internal business process. Therefore, Interest in BPM(Business Process Management) has grown rapidly. BPM is recognized as best solution to meet the needs of organizations that seek the cost down, integration of information, reducing of risk, improvement of productivity. In the past, the company have usually made huge investments in knowledge management systems which are based on repository keeping tacit knowledge. But this paper shows feasibility of implementation of business process-based knowledge management system that could link knowledge with business process. From an academic point of view, Although There could be several ways to build the business process-based KMS. In this paper, when BPM project and KMS project were started at the same time, the way of how to provide workers with task-related knowledge was discussed. As an case study, an estimate process of H company was analyzed and process modelling was carried out and conceptional architecture framework was depicted.

The data accumulated in this database will be used to develop a speaker identification system. This may also be applied towards, but not limited to, fields of phonetic studies, sociolinguistics, and language pathology. We plan to supplement the large-scale speech corpus next year, in terms of research methodology and content, to better answer the needs of diverse fields. The purpose of this study is to develop a speech corpus for standard Korean speech. For the samples to viably represent the state of spoken Korean, demographic factors were considered to modulate a balanced spread of age, gender, and dialects. Nine separate regional dialects were categorized, and five age groups were established from individuals in their 20s to 60s. A speech-sample collection protocol was developed for the purpose of this study where each speaker performs five tasks: two reading tasks, two semi-spontaneous speech tasks, and one spontaneous speech task. This particular configuration of sample data collection accommodates gathering of rich and well-balanced speech-samples across various speech types, and is expected to improve the utility of the speech corpus developed in this study. Samples from 639 individuals were collected using the protocol. Speech samples were collected also from other sources, for a combined total of samples from 1,012 individuals.

The objective of this study was to identify the job performance and perceived job importances of dietitians according to the characteristics of foodservice operations as well as dietitians. Questionnaires were distributed to 400 dietitians, and a total of 202 were received and utilized(50.5%). Statistical analysis of the data was performed using the SAS package program(version 8.2) for descriptive analysis and $X^2-tests$. The results are summarized as follows. The highest job task frequency was for sanitation management (98.5%); and then nutrition management (96.6%), cost management (92.6%), and inventory management (92.1%). The dietitians' perceived job importance was highest for sanitation management (74.3%), followed by nutrition management (68.8%) and human resource management (37.1%). Dietitians with under 3 years of experience had more difficulties, particularly in purchasing management, cost management, and sanitation management. Dietitians within contracted foodservice operations were dissatisfied by having insufficient education for cost management. Thus, programs for on-the-job and off-the-job training, reflecting dietitians' educational needs and changing job tasks should be increased.
