  • Every year respect a countermeasure establishment the electric leakage detection system and electric leakage investigation work are becoming enforcement line plentifully in about the electric leakage accident which is increasing, measuring in compliance with a most ground connection voltage and an image electric current mainly is become accomplished, inputs a pulsation group signal in the line and detects a signal change between the line a method which there is. In order to investigate the quality in compliance with an electric leakage electric current from the electric leakage area after conferring the electric leakage environment in compliance with a flooding when the electric leakage electric current exists in the surface, it investigated the electric leakage electric current quality from the electric current distribution and flooded districts from the present paper.

  • Leucaena leucocephala (lam. de Wit) is a multipurpose leguminous tree/shrub, promoted extensively for reforestation and rural development programmes, as well as in ruminant production. After a year of establishment in the plots, the overall leaves and twigs yield was on average 0.92 kg/plant, containing an average 23.34, 10.61, 5.32 and 10.13 percent CP, CF, and ash, respectively. The proximate and mineral compositions are affected by factors such as stage of maturity, type of cultivar, seasons, cutting intervals, different plant parts. Though leucaena contains toxic mimosine and tannins, these are not always deleterious for ruminants and rumen microbes can often degrade toxic factors into a nontoxic utilizable product Mimosine content is generally higher in the seed than other plant parts. Leucaena supplementation in ruminant ration showed higher digestibility co-efficient of proximate component, which may results in higher productivity. Considering its productivity, composition and nutritive value. L. Leucocephala could be more widely used as a protein source for ruminants in tropical and sub-tropical countries.

  • This paper analyzes the effects of allocative efficiency on productivity in the manufacturing sector of Korea following Hsieh and Klenow (2009). The results of this research indicate that the overall allocative efficiency declined from 1990 to 2012. Using the method of Oberfield (2013), which allows inter-industry resource movement as well as intra-industry reallocation, we confirm that intensified misallocation generally results from intra-industry allocative inefficiency. The potential loss from instances of worsening misallocation is estimated to be approximately 0.6% points for each year, which is considerable in terms of the overall TFP. In terms of the firm size distribution, initially large establishments are more likely to expand if distortions are removed in most countries. One notable feature in Korea is that this pattern is pronounced. This implies that subsidies to unproductive small-sized establishments are heavily implemented.

  • Articles from leading daily newspapers dealing with costumes analyzed here dating back to oughly one year before the I.M.F. system came into place in korea. The values and esthetic consciousness of that period were studied through fashion. The major conclusions of the study are as follows: 1. The values of exhibition conformity and extravagance were emphasized. 2. The beauty of play the beauty of the extraordinary and the beauty of splendour were expressed as the esthetic consciousness 3. Preference of young people toward expensive high-grade and foreign-made brands was excessive Adults have to guide the young not to overconsume. Development of a sounder culture of clothing is needed for the establishment of economic prosperity for the nation.

  • Since it's establishment Malaysian Center for Remote Sensing (MACRES) has focused on the measurements from airborne and space borne remote sensors. In the year 1999 MACRES in collaboration with Multimedia University Malaysia (MMU) began developing it's own remote sensing sensors to meet Malaysian Remote Sensing needs. MACRES adopted a very systematic approached to the development of these microwave sensors. Starting from non-imaging ground base microwave remote sensing sensors MACRES is now well into developing it's first Airborne Synthetic Aperture Radar. With the capability of developing it's own sensors MACRES will profit more on the microwave remote sensing application research. This paper will demonstrate MACRES capability in developing Microwave Remote Sensing Sensors to meet Malaysian remote sensing society needs.

  • Because of the limited land resources, an efficient land use management to reach the sustainable development policy has become an urgent call in Taiwan. A long-term project entitled 'National land use monitoring program-the establishment of a land use change detection system' has been jointly conducted by both National Central University and Ministry of Interior since year of 2001. The main aim of the project is to use the remote sensing images to detect the land use changes on a national scale. This plan has been put into practice and indeed provides an effective assistance for land management.

  • This paper is to show the history and the brief present situation, the further vision and the considerations of Vojta physical therapy. Since Vojta therapy has been introduced into Korea in 1980, the workshop had the total 7 times and has produced 76 Vojta physical therapist during the past 15 year. But Vojta thrapist members have a gradually declining tendency in the present state. The counterplans for the considerations as follows; 1) Physician and Vojta therapist must be concerned about the growth of Vojta diagnosis and therapy. 2) As the medical examination and treatment system's establishment, an early infant's tretment will be performed. 3) The course of workshop in Korea must be admitted to be a regular qualification by the Vojta center of Germany. 4) Cerebral palsy treatment need home care system by Vojta therapist. 5) Vojta therapist has to reside in a public health center.

  • As Real Time Enterprise (RTE) has been spotlighted since the year of 2002, some advanced companies have been implementing the paradigm of RTE to its legacy systems and the number of the companies has been growing. However, the network infrastructures mainly based on fixed telecommunications network make the results of the RTE implementations fall short of their expectations. In this paper, we propose to construct the fixed-mobile convergence (FMC) environment to achieve RTE. The convergence infrastructure will improve user accessibility to all kinds of data and will encourage the users to interact with the systems.

  • In this paper, the preliminary transfer orbit analysis results for the COMS mission were presented. As the first step of transfer orbit analysis, the preliminary analyses of LAE burn strategy, geometrical visibility, and launch window were performed. For the analysis process, all launcher nominates were divided into three groups according to the declination of LAE thrust angle. So, the three launch cases were assigned as the representative launcher of each group, respectively. They are Ariane-5, Atlas summer and winter launch cases. And all analyses were performed at the representative launcher of each group. One nominal and three back-up plans were considered for the establishment of LAE burn strategy. And for geometrical visibility analysis, four TT&C ground stations were considered. Finally, the preliminary launch window analysis was performed about the duration of one year from the first day of September 2008. The analysis results show that the all launch cases comply with the transfer orbit operation requirements.

  • Nitrous oxide ($N_2O$) is one of six greenhouse gases listed up in the Kyoto Protocol, and it effects a strong global warming because of its much greater global warming potential (GWP), by 310 times over a 100-year time horizon, than $CO_2$. Although such $N_2O$ emissions from both natural and anthropogenic sources occur, the latter can be controlled using suitable abatement technologies, depending on them, to reduce $N_2O$ below acceptable or feasible levels. This paper has extensively reviewed the anthropogenic $N_2O$ emission sources and their related compositions, and the state-of-the-art non-catalytic and catalytic technologies of the emissions controls available currently to representative, large $N_2O$ emission sources, such as adipic acid production plants. Challengeable approaches to this source are discussed to promote establishment of advanced $N_2O$ emission control technologies.
