  • Decrease in Population and graying of rural area by industrialization and urbanization are gone continuously. This makes happened various rural problems and the differential of standard of living with is arising day by day. Government is unfolding rural supporting project to solve continuously these problems. Recent Projects which are choosing not top-down process by government leading but bottom-up process through village inhabitants' participation and expert consultant get positive estimation. But those have difficulties because the support is attained only in the beginning step not continuously and inhabitants' number by graying is decreasing. The Special Economic Zone for Regional Development Policy is new access that regulation can differ according to special quality of each area depending on Localization Age. Through this transfer the competence that can mitigate or reinforce various regulations according to special quality of area in local government. So, back and maintain activation systematically so that each area could be developed specially. The purpose of The Special Economic Zone for Regional Development Policy is the activation of regional economy through development that regional specific character is. And there is characteristic that local government plans and takes the lead in all project contents, government gives regulation benefit by appointing the special economic zone and do not support finance and various tax remissions. Through investigation of such new policy, I wish to recognize what long-term plan and method could be possible to success rural activation continuously.

  • 최근 LCD제품은 고유한 특장인 경박단소가 요구되면서, 기존의 Back Light Unit(BLU) 로는 대응할 수 없는 사양으로 진화되고 있다. 기존과 동일한 설계개념으로 접근시에 시장에서 요구되는 중량, 두께, 휘도의 사양을 만족시킬 수 없으며, BLU의 주요광원인 CCFL(Cold Cathod Fluorescent Lamp)의 휘도 개선 또 한 한계에 다다르고 있다. 따라서 앞으로의 BLU 의 고성능화는 최적화, 고효율화로의 개발 전개가 예상되며, LCD의 고해상도에 따른 투과율 저하를 보상하기 위한 고품질 BLU의 개발이 시급한 상황이다. 본 연구에서는 이러한 BLU의 고효율화, 고품질화를 달성하기 위한 고성능 도광판 개발과 관련하여, 실물 제작에 앞서 광학시뮬레이션을 통한 이론적 접근을 수행하였다. 연구 결과, 상측에서 정각 $90^{\circ}$ 에 높이 $50{\mu}m$ 하측에서 정각 $80^{\circ}$ 높이 $28{\mu}m$일때 평균조도가 71.52W/m^2 구현됨을 알 수 있다. 이 결과를 바탕으로 통상의 인쇄 방식 도광판에 비해서 약 20% 정도의 휘도향상이 가능함을 알 수 있었다. 또한 차후 본 결과를 바탕으로 한 실물 제작을 통해 설계 시뮬레이션 결과와의 비교를 통해서 정확한 예측이 가능한 시스템을 구현함을 목적으로 하였다.

  • 'Gwanha' is new strawberry (Fragaria ${\times}$ ananassa Duch.) cultivar, which was released by Highland Agriculture Research Center, Rural Development Administration, in 2011. In 2007, this cultivar was originated from a cross between 'Sucambodiaberry' and 'Selva' that showed excellent ever-bearing characteristics including continuous pink flowering habit under long-day and high temperature condition. It was named 'Saebong No.4' after examining its characteristic and productivity in summer culture from 2009 to 2011. After characteristic and productivity test in 2011, 'Gwanha' was selected as an elite cultivar. The general characteristics of 'Gwanha' include spreading type, middle vigor, elliptic leaf, and long cluster in growth. The fruit shape is wedge, and the red fruit is edible and unique among the domestic ornamental strawberry cultivars. Flower color of 'Gwanha' is pink, and flower cluster is more appearance than 'Pinkpanda'. The average fruit weight of 'Gwanha' is about 7.8 g and the marketable yield is relatively low because of low marketable rate. It is resistant against fusarium wilt. 'Gwanha' is suitable for four season cultivation as an ornamental strawberry cultivar because it shows continuous flowering habit under long-day and high temperature condition.

  • Traditional agriculture technology is absolutely valuable not only to preserve biological diversity but construct an eco-friendly agricultural system. As the awareness of food safety has been growing, traditional technologies in the past agriculture literatures have obtained more attention sine chemical or synthesized fertilizer and agricultural pesticide were not used in these traditional agriculture ways. This study aims to evaluate development values on six kinds of agriculture literatures published before initial 1970s using Delphi technique and Correspondence analysis. The domains of assesment are include livestock sanitation, breeding management, feeding program and an extra part which 261 traditional agriculture technologies were first extracted from. From these technologies, livestock experts deducted 228 items and selected items more than 3.0 from all three areas including usefulness, scientific characteristic and economical efficiency utilizing Delphi technique.: 35 items from usefulness, 31 items from scientific characteristic, and 18 items from economical efficiency. The 23 technology items were finalized after adding five modern feasibility items recommended by experts to 18 items gaining more than 3.0 in at least three areas. The agriculture technologies were categorized into four areas where were analyzed using Correspondence analysis. The results revealed that 'sustainable farming technology', 'scientific character verification', ' modernized technology development', and 'intellectual property right' were placed closely one another except 'economy efficiency'. The result implicated that scientific verification and economy efficiency should be considered in order to sustain traditional agriculture technology into a modernized way and to protect intellectual property right of these technologies.

  • 'Snow Angel' was developed by National Institute of Horticultural & Herbal Science in 2008. A cross was made between phalaenopsis '0361', a white and red lip small-medium variety, and Phalaenopsis 'S98PN1', a white and dark pink lip small-medium variety with pink net pattern. The seedling materials were cultivated to 83 seedling lines from 2000 to 2002. The white and pink lip small-phalaenopsis '99-0404-13' with flowers of round shape was selected by individual selection. The selected line was multiplicated and the growth characteristics were investigated for the first characteristic trial from 2003 to 2007. It was named as 'Wonkyo F2-18' in 2008 and investigated for the second characteristic trial of growth characteristics. The examination was executed for stability, uniformity, yearly reproducibility, and public fancy. It was selected as a high quality cultivar with excellent flower shape and flower color from the selection council of new cultivars for agricultural products, there after it was registered as 'Snow Angel' in 2008.

  • The flooded type battery is used for solar lighting system. Because the characteristic of flooded type battery is the short life time, the maintenance cost is high. So the using flooded type battery in this system is inappropriate. The valve regulated lead acid batter.(VRLA) is the maintenance free and cycle service purpose. This paper presents the development of control system and monitoring system to applied VRLA battery for maintenance free and long life time in system.

  • The plasma oscillation has been observed in an argon pressure between a tungsten anode and cathode consisting of an aqueous conducting solution. The effects of experimental parameters on the electrical characteristics of the glow discharge have been studied. The experimental parameters include the anode-cathode distance, pressure, methanol flow rate, and cathode materials. The glow discharge with liquid cathode and solid anode showed the potential sensitive detector for HPLC

  • "Epigenetics" means the study of heritable changes in gene-activity without changes in DNA sequences. Methylation of the cytosine residue in a CpG dinucleotide sequence is a characteristic of the vertebrate genome. In vertebrates, methylation of DNA mainly occurs at the 5′-position of cytosine in a CpG dinucleotide forming 5-methylcytosine. Methylation of DNA plays a profound role in transcriptional repression of gene expression through several mechanisms. Generally, DNA of inactive genes is more heavily methylated than that of active ones; conversely demethylation of DNA reactivates gene expression in vivo and in vitro.
