It was mathematically analyzed at which steps to activate TTI in the cold chain for Alaska pollack, assuming that the performance of a commercial TTI product, and Fresh-check, could not always be optimized for the pollack. Three places were selected for the TTI activation, such as on fishing ship, Busan cooperative fish market, and mart. First, the kinetic and Arrhenius temperature dependent models were experimentally built under isothermal conditions. The color index of TTI and the level of Pseudomonas spp. of pollack were measured at time intervals. Second, the resultant models were used in the mathematical calculations for dynamic temperature conditions included in the cold chain. As a result, the TTI activated at the mart place showed the best agreement between the spoilage time of the pollack and the time for the TTI color to reach its end-point. It was therefore found that it is practically important to optimally select the TTI activation place or time when using a commercial TTI product.

The influence of the storage temperature at $15^{\circ}C$ on the biochemical and structural changes in the red muscles (M. sternomandibularis) of korean native cattle postmortem were studied. The results obtained were summarized as follows; 1.5 to 2 hours postmortem the pH-value had dropped to $6.7{\sim}6.8$, after 18 or 20 hours at $15^{\circ}C$ it had reached its final pH-value (5.5). The irreversible loss of extensibility, i.e. the onset of rigor mortis, arose at $15^{\circ}C$ between 9 and 10 hours postmortem at pH 6.1 to 6.0 and R-value between 1.05/1.10. The complete loss of extensibility postmortem was reached after 18 to 20 hours at pH 5.5/5.6. Muscle and sarcomere length of korean native cattle were contracted about 20% and 15%, respectively at $15^{\circ}C$. Meat of korean native cattle had the highest shear force (4.7 kg) on 1 day after slaughter. The tenderness was increased with the ripening period prolonged and was highest at the end of the 9 day ripening period.

In general, furniture industry, with its high foreign dependency, has serious logistics issues that are commonly raised in such countries as Korea, China and Japan. This leads to my different possibilities & ways of rationalizing the logistics systems that utilize port hinterlands. Thus the purpose of the present paper is to create new logistics systems which will work effectively across the three countries. In this research study, we came up with 2 logistics models in which the port hinterland of Busan serves as the distribution center for furniture industry, and the models were suggested as the cooperative logistics business systems for the North-east asian region. In the proposed models, 'Busan furniture logistics center' has the dual functions of 'the cross-docking center from China to Japan' and 'the assembly & delivery center for furniture imported by Japan'. To have this logistics business center materialized, we propose that policy-level supports from the relevant port authorities be provided in the following three aspects: overseas investment promotion focused on the furniture industry of Japan, protection & enhancement of competitiveness for the port of Busan, and uilization plans for the new port hinterland of the city.

Injury in agriculture is a serious public health issue with a major impact on the lives of Korean farmers. It is one of the leading causes of death and is also a major cause of longand short-term disability. In 2001, the social cost of one accident in agricultural machinery was estimated as 97.7-97.8 million won that is 4 fold of farm household income in Korea. Effective prevention and control of injuries requires a system of surveillance that monitors the incidence of injuries, their causes, treatment and outcomes. This requires an integrated system of data collection, analysis and interpretation and communication. Creating effective injury surveillance system in Korea requires to establish a framework for a national agenda. Discussions regarding the development of the framework should address, but not be limited to issues related to Data Holdings and Linkages; Capacity and Skills; Communication; Interconnection; and Surveillance Products. Ideally, an injury surveillance system would meet the information requirements across all sectors, while allowing each to have the ongoing information it needs for its policy and programming needs. This study was carried out to develop a surveillance system of agricultural injuries in Korea. Study subjects were residents who lived in a typical agricultural area (Yangpyung area in Kyung-gi province). The main data sources were reports of village headmen, compared with data of 'National Emergency Management Agency', 'National Health Insurance Corporation', 'Insurance of National Agricultural Cooperative', and 'Emergency Medical Centers'. Each data were reviewed to validate the strengths and weaknesses.

Masked fake face detection using ordinary visible images is a formidable task when the mask is accurately made with special makeup. Considering recent advances in special makeup technology, a reliable solution to detect masked fake faces is essential to the development of a complete face recognition system. This research proposes a method for masked fake face detection that exploits reflectance disparity due to object material and its surface color. First, we have shown that measuring of albedo can be simplified to radiance measurement when a practical face recognition system is deployed under the user-cooperative environment. This enables us to obtain albedo just by grey values in the image captured. Second, we have found that 850nm infrared light is effective to discriminate between facial skin and mask material using reflectance disparity. On the other hand, 650nm visible light is known to be suitable for distinguishing different facial skin colors between ethnic groups. We use a 2D vector consisting of radiance measurements under 850nm and 659nm illumination as a feature vector. Facial skin and mask material show linearly separable distributions in the feature space. By employing FIB, we have achieved 97.8% accuracy in fake face detection. Our method is applicable to faces of different skin colors, and can be easily implemented into commercial face recognition systems.

As part of the ongoing global process of airlines forming strategic alliances, Korean Air has become a member of the SkyTeam Alliance, while Asiana has joined the Star Alliance. However, as something akin to the Anti-Trust Immunity(ATI) initiative has not been ratified domestically, these two airlines have seen their roles within these strategic alliances significantly reduced. In keeping with its domestic airline liberalization policy the U.S. government has instituted a mechanism through which foreign airlines that join such strategic alliances with their American counterparts can be exempt from the U.S. antimonopoly law. As a result, U.S. airlines have been able to forge wide ranging cooperative relations with foreign airlines, and thus increased their competitiveness within the air transport industry. This study analyzes the applicability of this Anti-Trust Immunity initiative to the domestic environment.

This study was conducted to compare three models: two random regression models with and without considering heterogeneity in the residual variances and a lactation model (LM) for evaluating the genetic ability of Holstein cows in Korea. Two datasets were prepared for this study. To apply the test-day random regression model, 94,390 test-day records were prepared from 15,263 cows. The second data set consisted of 14,704 lactation records covering milk production over 305 days. Raw milk yield and composition data were collected from 1998 to 2002 by the National Agricultural Cooperative Federation' dairy cattle improvement center by way of its milk testing program, which is nationally based. The pedigree information for this analysis was collected by the Korean Animal Improvement Association. The random regression models (RRMs) are single-trait animal models that consider each lactation record as an independent trait. Estimates of covariance were assumed to be different ones. In order to consider heterogeneity of residual variance in the analysis, test-days were classified into 29 classes. By considering heterogeneity of residual variance, variation for lactation performance in the early lactation classes was higher than during the middle classes and variance was lower in the late lactation classes than in the other two classes. This may be due to feeding management system and physiological properties of Holstein cows in Korea. Over classes e6 to e26 (covering 61 to 270 DIM), there was little change in residual variance, suggesting that a model with homogeneity of variance be used restricting the data to these days only. Estimates of heritability for milk yield ranged from 0.154 to 0.455, for which the estimates were variable depending on different lactation periods. Most of the heritabilities for milk yield using the RRM were higher than in the lactation model, and the estimate of genetic variance of milk yield was lower in the late lactation period than in the early or middle periods.

The purpose of the NCS-based curriculum is to prepare students for practical competencies to perform tasks demanded by industries by applying nationally and industrially developed and certified NCS to the currently held curriculum. In order to achieve this academic goal, education institutions must dedicate their utmost efforts to train trainees to attain flexibility in rapidly changing industry environments and competitiveness to perform the various tasks demanded by industries. The 47th article of the Higher Education Law explains that the purpose of the College corresponds with that of the NCS-based curriculum because the contribution of national and social development is related to the development of an industry. The college purpose and the NCS-based curriculum require close collaboration and cooperation between industries and colleges. This thesis analyzes cases of industry and college cooperation, researches adequate cases that suit the purpose of the NCS-based curriculum and proposes an appropriate industrial-education cooperation model that suits college and NCS-based curriculum by analyzing the cooperation model held by highly acknowledged universities oversea. In addition, this paper proposes a process and guideline to establish the industrial-education cooperation model. The industrial-education cooperation model proposed herein not only practically aligns the NCS-based curriculum to fit the industry environments, but also supports each party in pursuing and achieving its goals through an effective cooperative structure. The NCS-based industrial education model is anticipated to improve colleges' employment rates, allow industries' procurement of brilliant human resources, and contribute to the development of domestic industries through effective college education and training competent professionals for society.

The aim of this paper is to explore the role played by the endogenous farming organization sustaining rural community's competitiveness. Nulmi-Ri, Chungdo Kun in Kyongsangbuk-do chosen as a case study area is known to be one of the most competitive rural communities, making a living with a peach farming. This community maintains its competi- tiveness by operating a community-based filming organization which was organised in an endogenous way. Most of individual farmers in this community belong to the farming organization and they have cooperative relationships in the processes of production and distribution. In this respect, the exchange and circulation of knowledge, and collective learning, tend to be significantly taken place between the organization members. Based on the experience of the Nulmi-Ri's endogenous farming organization, we propose some constructive comments for rural community development.

As the interest and the importance of environmental protection increases rapidly, the environment considers to be not only the item that requires a control and a duty fundamental element but the fundamental element to enhance the internection icompetitiveness n so. Along with the collapse of the foreign trade barrier and the quality improvement of a customer's life qu life of a an object is shortened liforder to sectsfy the customer's lemands and as the result of it quaother critical issues rmparding the waste treatment and recasles are now thought to be momentou onlyaddition to the issue of the greenhou e gases reduction that is considered as one of me q issues among many internection ienvironmental issues. To keep up the pace with the environmental flow qube notd countries have nlreal iput their attempts to solve this environmental problems through a number of rmpulactios and acctios and they have showed a great concern for it as it is an internection iproblem that they should aasroaeronlythe aspect of not just a compan isr a country but of the wte e globn ivillage. Sueroenvironmental flow alemaned the logistic stratmpy of a compan iand it brought up the demand for the reverse logistics in a supply chain. For the reason above, the concept of reverse logistics and classification, the comparison with any similar concepts and its necessity are studied in this research through the theoretical consideration and the current state of the reverse logistics is organized in this research by acknowledging the domestic development process and the properties regarding the recycles of resources. In addition, the way to apply to the nation was investigated by comparing with the environmentalism development process, the reverse logistics policies and examples of advanced countries in logistics. The research proposed building of intimate cooperative system between a shipper and logistic service provider for the reverse logistics throughout the whole supply chain, the financial support, amendment of regulations, support Eco-friendly logistic technology development and the propagation, effective logistic system development and others and it is expected to bring a significant meaning to the reverse logistic policy and operation later on.
