In this study, we have developed a prototype of the automatic defects detection system for capsule inspection using the computer vision techniques. The subjects for inspection are empty hard capsules of various sizes which are made of gelatine. To inspect both sides of a capsule, 2-stage recognition is performed. Features we have used are various lengths of a capsule, area, linearity, symmetricity, head curvature and so on. Decision making is performed based on average value which is computed from 20 good capsules in training and permission bounds in factories. Most of time-consuming process for feature extraction is computed by hardware to meet the inspection speed of more than 20 capsules/sec. The main logic for control and arithmetic computation is implemented using EPLD for the sake of easy change of design and reduction in time for developement. As a result of experiment, defects on size or contour of binary images are detected over 95%. Because of dead zone in imaging system, detection ratio of defects on surface, such as bad joint, chip, speck, etc, is lower than the former case. In this case, detection ratio is 50-85%. Defects such as collet pinch and mashed cap/body seldom appear in binary image, and detection ratio is very low. So we have to process the gray-level image directly in partial region.

The objective of this study was to analyze the reality of the program development process in detail accomplished by the organizations of extension education in through the hermeneutical approach. To achieve this purpose, this study tried to find answers to the following three questions : (1) how the organization of extension education develop their programs for farmers? (2) what is the programmers' awareness to the process of program development? and what is the reason for their thought and action to do so. (3) can be discussed integrally the findings for drawing some implications? The qualitative data were mainly gathered through participation observation and unstructured interview. And the qualitative data were analyzed by (1) noting pattern and themes, (2) seeing plausibility, (3) clustering, (4) making metaphors, (5) factoring, and (6) building a logical chain of evidence which hermeneutical techniques far drawing the meaning from the gathered data. The findings of this study were as follows: The programmers of this organization carried out the developing program in the technical training division at the national level and the section of fostering farm manager at the county level for the purpose of delivering the agricultural new technology and the agricultural policy. The term used formly in this organization was `curriculum development for former', and the reality of program was `instruction profile` which signified the set of the educational manin contents. At county level, Educational planning was stressed on the implement of educational administration.

Purpose: The purpose of this study was to explore the experiences of bereavement for main family members who had made and followed DNR decision for their family members. Method: This qualitative study was based on a grounded theory, and used in-depth interview techniques with the bereaved 10 main family members who had been treated and died under DNR order. Results: The causal condition of the family member was 'Releasing', and the main consequent phenomenon were 'Blaming self and ruminating'. The contextual condition was 'The memory of the deceased'. The action/reaction strategy was 'Purifying'. The intervening condition was 'Supporting system', and the consequence was 'Acceptance'. The experience after bereavement of the family member on DNR decision were rational processes that purified themselves and healed the guilt feeling about the decision from reflective assessment and response about DNR decision. Based on this results, the substantive theory 'Reflective self healing' was derived. Conclusion: The main family members in following DNR decision are more likely to have unhealthy emotional condition than others in normal bereavement process. But they overcame the grief of bereavement through reflective self healing process.

Future war needs a lot of changes for military organization. Specially, concept of the "Speed" is raised importantly after Iraq war of U.S. Armed Forces. So, He is a lot of studying supply chain for logistical support speed improvement. Korea Marine Corps has made an efforts to improve supply chain. However it is real that is putting various techniques by prescription rather than fundamental change. These simplicity prescriptions are not only systematic but also insufficient for Marine Corps' survival. In addition, Korea marine corps in actuality is depending on many members in marine and navy in feed chain. Thus it is not establishing even tactical, decision-making plan of operation for support ability cultivation. Therefore, in this study, with Sense and Response concept that is United States Marine Corps' support strategy, presented theoretical background and basis frame that serve that Korea Marine Corps's supply chain changes to perception reaction formation.

Recently, To define an enterprise's survival strategy is a difficult task, because the competition of a business is a complexity. The reason is the original research uses a statistical survey method. On a conceptual point of SCM, - as an order of development, physical distribution, logistics management, basic supply chain management and advanced supply chain management etc - a supervisor is magnifying gradually as well as confusing with information and analysis techniques which seems possible. On executing this, however, it has many problems since it is hard and wide; therefore, The Manager don't aware a total executable solution even though the enterprise knows necessity of SCM. On this paper focus on a proposal of alternatives with reasonableness of manufacturing and making a profit of sales department like most of enterprises are willing to overcome such as carelessness and unready strategy of investment additionally, the thesis should effort to find an element through an analysis of cases, a statistical method of effective SCM, and actual survey to propose an alternative; moreover, this paper proved the facts that it could be a guiding company, which has an ability of cooperation with entities through the founding of supply chain. As a conclusion, this essay showed the variation that influences the capacity entities and alternative to define an element which basically influence for a cause and effect.

Electrocatalysis of oxygen reduction reaction (ORR) using Pt nanoparticles or bimetal on carabon was studied. Currently, the best catalyst is platinum, which is a limited resource and expensive to commercialize. In this paper, we investigated the cheaper and more active electrocatalysts by making Pt nanoparticles and adding 3D transition metal such as copper. Electrocatalysts were obtained by chemical reduction based on ethylene glycol solutions. Elemental analysis and particle size were confirmed by XRD and TEM. The electrochemical surface area (ECSA) and activity of the catalyst were determined by electrochemical techniques such as cyclic voltammetry and linear sweep voltammetry method. The commercialized Pt support on carbon (Pt/C, JM), synthesis Pt/C and synthesis Pt3Cu1 alloy nanoparticles supported on carbon were compared. We confirmed that the synthesized Pt3-Cu1/C has high electrochemical performance than commercial Pt/C. It is expected to develop an electrocatalyst with high activity at low price by increasing the oxygen reduction reaction rate of the fuel cell.

Purpose: The purpose of this study was to gain knowledge of successful aging for the Korean elderly and to identify the effects of an intervention program on the change of the knowledge Method: Data were collected from 134 elders from 3 schools for the elderly in H City. The Successful Aging Scale was used to collect data and modified CDSMP was applied as the intervention. Descriptive statistics, t-test, ANOVA and ANCOVA were used. Results : The total score of the knowledge of successful aging among the elderly cohort was 2.44 out of 3, and the scores of the factors making up old age were 2.66 for the success of children, 2.63 for self-control, 2.56 for self-efficacy, and 2.05 for happy marriage. Life satisfaction from the success of children and self-control were strongly correlated(r=0.7036, p=0.000). Conclusion: The self-management program brought positive changes to the knowledge of successful aging through the self-control parameter, and although it could not change the degree of knowledge of the overall successful aging among the elderly cohort, the program represents the first Korean nursing intervention focused on self-management techniques needed for successful aging.

Recent advances in forward error correction (FEC) coding techniques were focused on addressing the challenges of multicast and broadcast delivery. However, FEC approaches can also be used for unicast content delivery in order to solve transmission control protocol issues found in wireless networks. In this paper, we exploit the error resilient properties of Raptor codes by proposing Raptor-based content delivery protocol (RCDP) - a novel solution for reliable and bidirectional unicast communication in lossy links that can improve content delivery in situations where the wireless network is the bottleneck. RCDP has been designed, validated, optimized, and its performance has been analyzed in terms of throughput and resource efficiency. Experimental results show that RCDP is a highly efficient solution for environments characterized by high delays and packet losses making it very suitable for intelligent transport system oriented applications since it achieves significant performance improvements when compared to traditional transport layer protocols.
