  • The desired level for multimedia services in the mobile web environment, the next generation web environment, is expected to be of PC level quality. And great efforts have been made in the development of hadware technology, communication technology, various kinds of services and standardization to support these services, In the mobile web environment, multimedia contents adaptation services should be available through supporting various kinds of devices, network abilities and users' preferences. It means that due to the variety of both desired devices' hardware specifications, called destinations, and desired QoSes, the QoSes in the destinations are not fixed or defined. If a new user wants to stream multimedia contents in a server through a new kind of terminal device, it should be considered whether the existing transcoders are able to adapt the multimedia contents. However, the existing libraries for multimedia adaptation have heavy transcoder figures which include all adaptive functions in one library, The challenge of universal access is too complex to be solved with these all in one solutions. Therefore, in this paper we propose an application independent multimedia adaptation framework which meets the QoS of new and varied mobile devices. This framework is composed of a group of unit transcoders having only one transcoding function respectively, Instead of heavy transcoders. Also, It includes the transcoder manager supporting the dynamic connections of the unit transcoders in order to satisfy end to end QoS.

  • Anaerobic soils limit the amount of free oxygen available in the rhizosphere and therefore will impede grass root development and restrain nutrient availability for turf growth. An in-situ study was conducted on existing greens to investigate the relationship between $CO_2$ content in the rhizosphere and turf quality. Nine greens were selected in the study. On each green, five 1-m diameter circular plots were randomly selected for conducting the experiment. The greens were sampled 7 times from August, 1998 to August, 1999. Data collected from each plot included turf quality index, $CO_2$ content, and physical properties of the rooting mixtures. Turf quality declined drastically when $CO_2$ content in rhizosphere increased to $5\;to\;6{\mu}LL^{-1}$ during the late summer season. The $CO_2$ content increased as water content in the root zone increased, but was inversely related to infiltration rate. Cultivation of a golf green may reduce $CO_2$ content in the rhizosphere, but the benefit of cultivation decreased with time.

  • This study was designed to determine the effect of season and split-sex feeding on performance, stress and carcass quality of finishing pigs. Two hundred and seventy cross-bred finishing pigs $(82.1{\pm}0.82kg)$ were randomly divided into six groups in 2 seasons (summer and winter) ${\times}$ 3 split-sex feeding (female only, castrated male and mixed) factorial arrangement of treatments. In winter, feed intake and weight gain of finishing pigs were better than summer (p<0.05). Split-sex feeding was affected the feed conversion, feed conversion of finishing pigs were superior in winter and mixed groups. Plasma concentrations of cortisol as a stress indicators was greater in the mixed groups vs female only and castrated male groups. There were no interactions between the season and split-sex feeding in their effects on these blood variables. The season was affected the carcass characteristics and PSE incidence of the finishing pigs, PSE incidence was low in winter and mixed groups. Meat quality did not show any significant difference due to the difference of season and split-sex feeding of finishing pigs. There was no significant difference in the pH, drip loss and meat color of pork loin between the season and split-sex feeding of finishing pigs. In conclusion, the results of this study suggest that we need more precise on-farm management practice in summer and application of split-sex feeding skills to reduce the stress and improve welfare status of finishing pigs.

  • Superintendents have been used microbial fertilizers to improve turfgrass growth and quality and to decrease turfgrass diseases in golf course. This study was conducted to investigate the effects of compound fertilizer containing microbe (MF) on the growth and quality of creeping bentgrass with turf color index (TCI), chlorophyll index (ChI), root length, turfgrass density, clipping yield and nutrient content. Treatments were designed as follows; non-fertilizer (NF), compound fertilizer (21-17-17; CF) as control, compound fertilizer (14-6-17) containing microbe. In pot experiment, TCI and ChI of creeping bentgrass in MF plot were similar to those in CF. But clipping dry weight of MF plot increased by 39.1% compared to that of CF plot. At field experiment applied with MF treatment, TCI, ChI, root length, and nutrient content and uptake of creeping bentgrass were similar to those with CF treatment, but turfgrass density with MF higher about 7.9-15.8% than with CF. These results indicated that the application of MF improved growth and quality of creeping bentgrass by enhancing clipping yield and shoot number.

  • Present TCP/IP networks have some service quality problems. They delay various kinds of traffic, while increased traffic bottle necks, a phenomena experienced by too many internet users. Therefore, as use of the network increases, building up a stable network service is needed. Thus, network managers desperately need the best, most effective traffic control and wide-band services. Until now there has been no other way of increasing wide-band use of lines, particularly because of the expenses a limit solutions of solving continuously to increasing traffic problems. This study suggests a problem solving method under the base of 802.16e(Wibro) which will be widely used in the future.

  • Recently, utilization of PMIS(Project Management Information System) is in high demand as it is desired to advance the construction market through cost reduction and quality improvement within the given schedule. However, PMIS developed by individual projects are mostly evolving around construction progress status due to the temporary nature of development period and use of the system by project executers is no more than perfunctory that results in limiting the effective communication between the project owner, project manager and constructor. Therefore, the purpose of this paper is to review the PMIS developed so far, and present the direction for an effective PMIS.

  • The purpose of this study was to analyze and evaluate the menu served in business & industry contract foodservice by assessing nutritional value and by using menu-engineering technique from managers' view point. CAN-Pro program and Kasavana k Smith's Menu Engineering technique were used to evaluate the nutritional value and menu analysis, respectively. The data were analyzed using the SAS package program for descriptive analysis, t-test, ANOVA, and Pearson Correlation Analysis. As the result of nutritional value of lunch menu, all nutrient contents per meal were higher than a third of Korean recommended dietary allowances(RDA), But there was no problem when 20∼30% of plate waste was considered. Carbohydrate : Protein fat ratio was 62.7 : 16.4 : 20.8. Because animal : vegetable source ratios of protein, fat, calcium, iron were 44 : 56, 42 : 58, 22 : 78, 24 : 76, respectively, animal sources of calcium and iron needed to be supplemented. Plural set menus of A site were classified as STAR, PUZZLE, PLOWHORSE, DOG by Menu engineering technique. Set menus and soups & pot-stews among cafeteria menus in C site were operated properly without DOG and PUZZLE item. Side dishes of fishes, meats 8t eggs among cafeteria menus in C site were, for the most part, classified as STAR item, and side dishes of vegetables & salads and noodles among cafeteria menus in C site were STAR, PUZZLE, and DOG items.

  • 서비스 산업에 있어서 유통이라는 것은 서비스가 제공되는 접점으로 정교한 분석과 체계적인 연구가 이뤄져야 한다. 하지만 서비스 제품의 유통채널 전략에 대해서는 중요성을 인식하면서도 지금까지 그에 대한 연구와 관심은 미흡한 실정이다. 서비스 기업이 점점 더 경쟁이 치열해 지는 경쟁적 시장상황하에서 경영혁신과 서비스 제품의 유통혁신 전략에 대수술을 추진하고 있으나 그 내용을 보면 고객지향적인 발상과는 괴리가 있다는 점에서 더욱 심각하다고 생각할 수 있다. 본 연구에서는 서비스 기업이 유통채널 전략을 수립하고 실시해 가는 과정에 있어서 고려할 사항과 어떤 부분에서 메이커와의 이질적인 특징을 보이고 있는가를 분석하고 그에 대한 지침을 제시하였다. 서비스 제품의 고유의 특성(무형성, 동시성, 소멸성 등)들은, 첫째 그 유통채널 구조를 독특한 것으로 만들며, 둘째 유통채널 기능에 특징적인 것을 초래하게 하며, 섯째 유통채널의 설정은 유통채널의 설계와 유통채널의 선택이라는 두 가지 과정을 거쳐서 이뤄지며, 넷째 이러한 과정을 거쳐 유통채널을 선택하고 관리하도록 만들고 있다. 따라서 서비스 제품에 대한 제공 배달의 유통채널에 있어서는 서비스 제품에 대한 수요와 공급의 조정이나 그 제공 배달시점에서 품질의 유지향상에 관한 관리를 해 갈 필요가 있다. 또한 중간관리자에 대한 관리는 파워를 행사하거나 통제가 어려워 관리가 곤란하다고 볼 수 있으나 커미션, 수수료 등의 제공이나 딜러핼프 등을 강화함으로 극복해 나갈 수 있겠다. 결론적으로 서비스 기업이 유통채널 전략을 수립하여 실시해 갈 때에는 상술한 바와 같이 채널의 구조나 기능, 채널관리 등의 측면에서 메이커에서는 볼 수 없는 특징적인 적이 존재하므로 그 독자적인 유통채널 전략을 전개해 갈 필요가 있다고 생각한다.
