This study compares supply chain integration practices of high performing manufacturing plants in Korea and those in the U.S., Japan, and six European countries. Data were drawn from the High Performance Manufacturing(HPM) Round 3, a joint data-collection effort on manufacturing and supply chain management. Specifically, in the automotive, electronics, and machinery industries, we selected twenty Korean plants with high performance reputation and chose the same number of non-Korean plants(HPM top 20), based upon their competitive manufacturing capability index and customer satisfaction index. The Korean plants do not significantly differ from HPM top 20 plants in that internal value creation activities are coordinated and integrated at the corporate level and between plants. The Korean plants, however, demonstrated more integration with suppliers than with customers, and only the two of them were classified as 'outward facing', which pursues greater integration with both customers and suppliers. Unbalanced and lower integration with customers of the Korean plants was attributed to the lower than expected manufacturing capability and customer satisfaction. Implications for supply chain professionals were discussed.

Numerical analysis of the radiant heat characteristic around heatsink according to arrangement and shape of fin on 60W-LED lamp is conducted in this study. In the case of top blow blowing from upper side on LED lamp, there is just little difference in cooling characteristics according to the height of fin. On the other hand, the fin arranged side by side has the advantage of heat transfer enhancement by comparing with zig-zag type because it leads to more loss of flow. In case of making fin round to increase the amount of heat transfer, designing arrangement with the minimized loss of flow has the advantage of characteristic.

6 Sigma movement is the quality innovation activity which Motorola, a nineteen eighties' top-ranking American company of electronics and communication, has started to survive the Japanese companies' frightening gami-gaze. In early days, it's just applicated for reducing customers' complain by eliminations inferior goods centering round producing activity and filling up the competitive market's demand for price and delivery deadline. Nowaday, 6 Sigma application has created a boom extending to a company's most activity fields without any exact scrutiny of 6 Sigma. Although 6 Sigma movement starts from the question of what customers want not by cutting off the inferiority rate but by cutting out causes of producing inferior goods, the service industry has a special character that makes it difficult to compute the level of Sigma. Thus this research examines suitability for introduction of 6 Sigma to the Service Industry.

Ni-diamond composite powders with nickel layer of round-top type on the surface of synthetic diamond (140/170 mesh) were prepared by the electroless plating method (EN) with semi-batch reactor. The effects of nickel concentration, feeding rates of reductant, temperature, reaction time and stirring speeds on the weight percentage and morphology of deposited Ni, mean particle size and specific surface area of the composite powders were investigated by Atomic Adsortion Spectrometer, SEM-EDX, PSA and BET. It was found that nucleated Ni-P islands, acted as catalytic sites for further deposition and grown into these relatively thick layers with nodule-type on the surface of diamond by a lateral growth mechanism. The weight percentage of Ni in the composite powder increased with reaction time, feeding rate of reductant and temperature, but decreased with stirring speed. The weight percentage of Ni in Ni-diamond composite powder was 55% at 150 min., 200 rpm and 7$0^{\circ}C$ .

Prior hardware-centered rural development projects implemented top-down rural community regeneration via the local government in accordance with central government agency policies. To improve this, software-centered projects have been promoted since 2000. With central agency-led rural development projects changing into local government-led ones, rural community regeneration has been built per village. Although rural community regeneration projects appear to have implemented a bottom-up development currently, the top-down development procedures being facilitated by the intervention of administrative institutions have not disappeared. In this regard, the purpose of this research thesis is to effectively perform bottom-up development methods that go one step further from the current process of rural community regeneration. As the research site, this thesis selected Geochang, which has difficulties in being steadily maintained and operated despite the development of various rural community regeneration projects. Subsequently, it determined the current status and substantial analysis of a project of the rural community regeneration in Geochang through 1:1 interviews with civil servants in charge of administration as well as conducted a prior study on rural resident awareness of rural community regeneration through a survey of village head members and in-depth interviews with rural residents. Based on these data, a 10 times-round table conference was held under the participation of pertinent civil servants, professionals and rural residents to select practical strategies for cooperative rural community regeneration in Geochang as five key areas: local food, culture & welfare, rural villages, community development, and urban and rural interchanges. In addition, it is considered that the project of building villages must be implemented by establishing steadfast administrative co-operation systems, strengthening rural residents' participation capacities and supporting professionals' systemic integrated operation and maintenance. By doing so, this research thesis sought to determine practical strategies in the cooperative rural community regeneration in Geochang. It is expected that bottom-up development rural community regeneration will be built and introduced in each rural community in the future.

This study was conducted to establish the shelf life of $1^{++}$ grade Hanwoo beef by evaluating the changes in meat quality and storage stability under distribution conditions similar to those during export to Hong Kong and China. Four muscles of the loin, striploin, tenderloin, and top round muscles were obtained from 10 animals of $1^{++}$ grade Hanwoo steers. The distribution conditions were 0, 7, or 14 d of aging at $2^{\circ}C$ and continuous storage at $-18^{\circ}C$ for 0, 3, 6, or 9 mon. The lightness (CIE $L^*$) values decreased as the duration of freezer storage increased (p<0.05). The water-holding capacity of 4 muscles increased as the aging time increased when they were frozen for 3 mon (p<0.05). The cooking loss values of the four muscles were significantly increased as the duration of freezer storage increased (p<0.05). The Warner-Bratzler shear force values were significantly decreased in the loin, striploin, and top round muscles as the aging time increased (p<0.05). The changes in volatile basic nitrogen (16.67-18.49 mg%) and thiobarbituric reactive substance values (0.75-0.82 mg MA/kg meat) were significantly increased when the meat was frozen for 9 mon after 14 d of aging. On the basis of these observations, the shelf life of $1^{++}$ grade Hanwoo beef during distribution should be limited to less than 9 mon of freezer storage at $-18^{\circ}C$ after 14 d of aging at $2^{\circ}C$.

Objective: This study was conducted to generate single stranded DNA oligonucleotides with selective affinity to bovine spermatozoa, assess its binding potential and explore its potential utility in trapping spermatozoa from suspensions. Methods: A combinatorial library of 94 mer long oligonucleotide was used for systematic evolution of ligands by exponential enrichment (SELEX) with bovine spermatozoa. The amplicons from sixth and seventh rounds of SELEX were sequenced, and the reads were clustered employing cluster database at high identity with tolerance (CD-HIT) and FASTAptamer. The enriched nucleotides were predicted for secondary structures by Mfold, motifs by Multiple Em for Motif Elicitation and 5' labelled with biotin/6-FAM to determine the binding potential and binding pattern. Results: We generated 14.1 and 17.7 million reads from sixth and seventh rounds of SELEX respectively to bovine spermatozoa. The CD-HIT clustered 78,098 and 21,196 reads in the top ten clusters and FASTAptamer identified 2,195 and 4,405 unique sequences in the top three clusters from the sixth and seventh rounds, respectively. The identified oligonucleotides formed secondary structures with delta G values between -1.17 to -26.18 kcal/mol indicating varied stability. Confocal imaging with the oligonucleotides from the seventh round revealed different patterns of binding to bovine spermatozoa (fluorescence of the whole head, spot of fluorescence in head and mid- piece and tail). Use of a 5'-biotin tagged oligonucleotide from the sixth round at 100 pmol with 4×10⁶ spermatozoa could trap almost 80% from the suspension. Conclusion: The binding patterns and ability of the identified oligonucleotides confirms successful optimization of the SELEX process and generation of aptamers to bovine spermatozoa. These oligonucleotides provide a quick approach for selective capture of spermatozoa from complex samples. Future SELEX rounds with X- or Y- enriched sperm suspension will be used to generate oligonucleotides that bind to spermatozoa of a specific sex type.
