  • In the last couple of decades industrialization and technological development has not only increase in the scale of electrical facilities and it has become more and more complicated and diversified. Furthermore, fires in the electrical transformers, like those that have knocked out power in the country in the past years, are likely to become more common as utility systems begin to show their age. The importance of preventing electrical accidents can never be overemphasized and for this reason, supply of on-line diagnosis system combining information and communication technology(ICT) for the customer's electrical facilities has been increasing recently. The major advantage of on-line diagnosis system is that the device's potential problems could be detected early before a serious deterioration or breakdown occurs. In this paper, We estimated the benefit from the investment in the right of present value of sales, success rate of commercialization regarding R&D investment for development and commercialization of on-line diagnosis technology targeting customer electrical facilities. As a result, the net value added of 29.7 billion won and the increased profit by roughly 7.52 precent are expected.

  • Despite the remarkable advancements of the modern medicine, the traditional system of medicine (TSM) still serves as a potential primary health care modality in the in low- and middle-income countries. The recent reports suggest that there is a renewed interest has been observed towards TSM in the developed countries too, because of the adverse side-effect of modern medicines. Medicinal plants have been widely serving as a rich source of therapeutic agent. Ethiopia is one of the most reserves rich countries in the world. It is renowned for well-diversified and natural resources in terms of its unique flora and fauna. Ethiopian deep-rooted tradition and culture largely depends on the usage of plants for their religious ceremonies, impressive festivals, traditional medicinal uses and other basic necessities. The present scrutiny is an attempt to understand the omnipotent nature of an Ethiopian Ethnomedicinal plant called Tinjute [vernacular name (local native language, Amharic); Otostegia integrifolia]. There are several studies suggest that Tinjute can be used as a natural medicine or health-promoting agents for various disorders and ailments. Nevertheless, in Ethiopia, it is renowned as an insect repellent to drive-away insect vector of diseases, particularly mosquitoes in the early evening. However, there are many more issues and challenges which must be urgently addressed to scientifically formulate various potent, efficacious, safe and highly selective phytotherapeutic agents and insects' repellent from the Tinjute plant in the near future.

  • This paper is aim to report the core aspects of Codex guideline for organically grown food which is finalized by FAO/WHO Codex Alimentarius Commission on May 2000 in 28th session of the Codex committee on food labelling. The chapter of animal production had discussed for a long time before it was finalized in Ottawa/canada as well as use of GMO(Genetically modified organism), manure from factory farming, animal welfare, and fodder inputs consisting of at least 85% for ruminants and 80% for non-ruminants. As the guideline for Codex set out the several things which is very difficult for Asian country, Organic farmer in Korea should pay an attention to maintain/increase the fertility and biological activity by cultivation of legumes, green manures or deep-rooting plants in an appropriate multi-annual rotation programme, and incorporation in the soil of organic material from holding producing in accordance with the guidelines. Pest, diseases and weeds should be controlled by choice of appropriate varieties, appropriate rotation, mechanical cultivation, diversified ecosystems, flame weeding, animal weeding and steam sterilization. The use of plant growth hormone, GMO and manure from industrial management system are not allowed, and closed recycling system, rotation, resistant seeds again pest and disease should be practiced in organic farming. But these are not unfortunately practiced in the country. In the conclusion it was strongly suggested to enact the Basic Standard for Korean organic agriculture which contains the core principles of Codex guidelines, and to try the importation of the most advanced theory, skills and technology from leading country in organic farming.

  • During the last 10 year period, OECD member countries were in a trend of 'less government' from 'more government', thus resulted in restructuring and reducing staffs in government agricultural institutions including the Agricultural Knowledge System. In recognizing the crisis of 'less government', member countries were in a trend of paradigm shift to the 'better government;. In producing and transferring agricultural information, member countries are more concerned about consumers as well as producers as the target of good quality services of the 'better government'. The general consensus of member countries identified the importance of food safety and environmental protection as new agendas for the 21st century. Agricultural Knowledge Systems (AKS) in OECD member countries were in a trend of reorganization in addressing food safety, and agriculture / environmental issues. The approaches, functions and responsibilities were diversified to multi-governmental institutions from the ministry of agriculture. Thus the importance of institutional cooperation and coordination were emphasized more in the newly changed AKS paradigms. The objectives, functions and approaches of AKS in OECD member countries as well as in Korea will be directed to emphasize the importance of environment, sustainable agriculture, food safety, and rural development. They will also focus on establishing mutual cooperative systems among policy makers, consumes, non-governmental organizations, and agri-related organizations as necessary for sustainable development in the future.

  • This paper establishes a coding method system including the liberation and size distribution of recycling materials in the shredder operation. Every particle in the shredded product becomes a code number using the liberation model and size distribution equation transforming of weight percentage into particles number percentage. One set of database can be obtained after all particles have been coded. This database is suitable for the size reduction operation in the process simulation of waste recycling. Coupling with the developed air classification, sizing and separating operations, the whole process simulation will be completely established for diversified application. A typical simulation for the rolling cutting shredder product of waste TV had been demonstrated under this coding system. The breakage size distribution of Gaudin and Schumann equation were selected for the shredding operation simulation. The Gaudin's liberation model was suitable fur the liberation simulation. Both of these equations were transformed weight percentage into particles distribution for the necessary of particle coding method. A better recycling operation for this shredded solid waste can be concluded from the comparison of simulation results with their sorted grade, recovery or economic of materials in different processes.

  • To expect accurately the maximum power of solar cell module under various installation conditions, it is required to know the performance characteristics like temperature dependence. Today, the PV (photovoltaic) market in Korea has been growing. Also BIPV (building integrated photovoltaic) systems are diversified and become popular. But thermal dependence of PV module is little known to customers and system installers. In IEC 61215,a regulation for testing the crystalline silicon solar cell module, the testing method is specified for modules. However there is limitation for testing the module with diverse application examples. In extreme installation method, there is no air flow between rear side of module and ambient, and it can induce temperature increase. In this paper, we studied the roof type installation of PV module on the surface of one-axis tracker system. We measured temperature on every component of PV module and compared to open-rack structure. As a result, we provide the foundation that explains temperature characteristics and NOCT (nominal operation cell temperature) difference. The detail description will be specified as the following paper.

  • he objective of this study was to investigate home network systems presently applied in multi-housing complexes and resident's usage to improve the utilization of these systems and services as well as maintenance methods. Subjects were 27 housing complexes equipped with home network systems in west Pangyo area. The investigation methods of communal network systems were observed and photographed. Unit systems were investigated through photography, interviews, and observation focusing on the utilization of Wall-Pads by visiting one unit of each housing complex. The results are as follows: (1) Most housing complexes that we investigated were built with high-grade IT infrastructure. Also, remote meter reading, electronic security, vehicle access, and building access systems were established. Wall-Pads with similar functions were installed in 23 housing complexes, excluding private rental housing complexes. (2) Even though people were well aware of the need for common systems within their housing complexes, only 10~20% of Wall-Pad menus were used. (3) Low utilization rates of home network stem from Wall-Pad menus which were user-unfriendly, and a lack of user training for the complex's common system and unit system. Therefore, to promote active use of home network systems, the systems must be diversified in accordance with user characteristics. In addition, the Wall-Pad menus should be reorganized to be user-friendly.

  • This study is purposed to examine how fanner's living conditions and managements have been improved during the last five years(1985 through 1989) on the basis of the information got from the sample survey of 30 farm households chosen in Galma-ri, Buseok-Myeon, Seosan county, Chungnam province. The followings are major results of the study. (1) There have been much improvement of kitchen facilities and increasing number of cultural goods, but not much in the condition of sanitation facilities. (2) The size of farm warehouse and stall have been greatly enlarged and there has been large variation in the heads of big animals such as cattle during the surveyed period. This may reflect the facts that farm managements become more diversified and commercialized. (3) It is shown that fanners more voluntarily accept new fanning techniques about their concerning crops. Also there have been rapid changes in the pattern of upland cropping system, adjusting to the commercialization of agriculture. (4) Currently, fanners tend to react to the price signal of market system more sensitively than before. Accordingly, agricultural income structure is varied subject to price fluctuation in the short run period.
