This study conducted a result analysis on operation of 26 Rural Community Sewage Treatment Plant (RCSTP) newly constructed in Yeong-yang, Bong-hwa and An-dong areas which are located at the uper region of An-dong Dam and Im-ha Dam. Based on operation result, an analysis on characteristics of sewage in each areas and the treatment efficiency of the installed treatment process was conducted. The result of analysis on characteristics of sewage has shown the difference in concentration of the sewage according to area characteristics. Sewage in areas with frequent occurrence of agricultural water and livestock wastewater had high concentration. It is important to select the most suitable treatment process when selecting a treatment process for RCSTP according to properties of sewage in each area. As a result of operation, the disposal efficiency for organic matter and suspended solids was stable with less fluctuation, but the disposal efficiency for nitrogen and phosphorus showed high fluctuation. This signifies that it is necessary to pay attention to operation condition management of aitrogen and phosphorus when operating RCSTP.

With the increased use of lasers in industrial welding applications, techniques for monitoring and controlling these processes become increasingly important. It is very important that we understand the dynamic behaviors of the laser induced plume in welding because the laser induced plume has considerable effects on welding efficiency and the quality of materials. As the plume fluctuation was associated with keyhole instability, unstable vapor plume indicated the process was unstable and would result in poor welds. An Infrared Themal-vision Camera can be utilized compensate for incurracies encountered in real-time monitoring during laser welding. We have results that instabilities of plume are closely dated with hot cracking and defect of laser welding.
Yin and Yang of ginseng pharmacology: ginsenosides <i>vs</i> gintonin
Im, Dong-soon,Nah, Seung-yeol Nature Publishing Group 2013 Acta pharmacologica Sinica. Vol.34 No.11
<P>Ginseng, the root of <I>Panax ginseng</I>, has been used in traditional Chinese medicine as a tonic herb that provides many beneficial effects. Pharmacologic studies in the last decades have shown that ginsenosides (ginseng saponins) are primarily responsible for the actions of ginseng. However, the effects of ginseng are not fully explained by ginsenosides. Recently, another class of active ingredients called gintonin was identified. Gintonin is a complex of glycosylated ginseng proteins containing lysophosphatidic acids (LPAs) that are the intracellular lipid mitogenic mediator. Gintonin specifically and potently activates the G protein-coupled receptors (GPCRs) for LPA. Thus, the actions of ginseng are now also linked to LPA and its GPCRs. This linkage opens new dimensions for ginseng pharmacology and LPA therapeutics. In the present review, we evaluate the pharmacology of ginseng with the traditional viewpoint of Yin and Yang components. Furthermore, we will compare ginsenoside and gintonin based on the modern view of molecular pharmacology in terms of ion channels and GPCRs.</P>

2018년 6월 12일 노사정대표자회의 끝에 노사가 중심이 되고, 참여주체를 청년·여성·비정규직 및 중견·중소기업·소상공인 등으로 확대하며, 의제별·산업(업종)별 및 지역별 대화 체제를 강화하는 새로운 사회적 대화기구를 출범시키자는 데에 합의하면서 출범한 경제사회노동위원회는 노사상생형 지역 일자리 컨설팅 사업, 노사관계 네트워크 구축 및 노동단체 사회공공성 요구 등을 해결하는 데에는 한계를 노정시키고 있다. 본 연구 주 내용은 노사관계 협력 업무를 담당하고 있는 자치단체 공직자들이 이러한 현안 문제에 대한 대안을 탐구하는 의사결정과정에서 활용하리라 예상되는 e_거버넌스의 주요 내용들에 대한 종합적 중요도를 분석하고자 하였다. 이를 위해 Fuzzy-AHP 기법을 이용하였다. 연구에 사용된 분석기법은 첫째, 상대적 중요도를 분석하기 위해 AHP 기법을 사용하였으며 둘째, 쌍대비교를 통한 상대적 중요도 우선순위가 갖는 한계를 보완하기 위해 개발된 Fuzzy-AHP 중요도 보정 방법을 적용하기 위하여 λ 값과 상수 C값 산출하였고 셋째, 이 λ 값과 C 값을 적용하여 Fuzzy-AHP 종합중요도를 산출하였다. 분석결과, 의사결정 5 단계 가운데 광역자치단체 관계자는 ‘의제형성’에, 기초 자치단체 관계자는 ‘피드백’에 우선순위를 두고 있는 것으로 나타났다. 연구결과 도출된 내용을 중심으로 경제사회발전을 기할 수 있는 노사상생형 지역 일자리 컨설팅 사업, 노사관계 네트워크 구축 및 노동단체 사회공공성 요구 등에 부합되는 대안을 마련하는데 노사정이 합심해야 할 것이다. In this study the Comprehensive Priority of the e_Governance to Decision Process was analyzed and 36 officials in the two expert groups who are working for the metropolitan government and local government were selected for this survey. The 25 cases among 31 were finally used for the analysis of comprehensive priority by Fuzzy-AHP. As a result, the consequent statistics were revealed that most of the officials who joined in this study thought that the 'agenda making' has the top comprehensive priority in the decision process rather than the other items, agenda setting, agenda analysis, implementation, and feedback of the process. And when we looked into the results of Fuzzy-AHP comprehensive priority(table 7), e_information of the developmental stage of e_governance is the highest priority in the agenda setting of the decision process, e_decision in the agenda making and in the implementation, and e_information in the feedback Finally some suggestions would be found that on the basis of the results of this study the officials concerned in the public organizations would positively try to promote the utilization of e_governance for the economic and societal development and the co-living between labor sides and management sides.

본 연구는 순천시 선도 산림경영단지를 대상으로 사업투자에 대한 경제성 분석을 통해 향후 산림경영계획 수립에 대한 기초자료를 제공하는데 있다. 이를 위해 경제성 분석 지표인 NPV와 IRR 분석을 실시하였다. 경제성 분석 결과, 사업 10년차에서의 NPV는 241.9백만원, IRR는 8.5%로 선도 산림경영단지에 대한 사업투자는 경제성이 있는 것으로 나타났다. 그리고 사업이 장기화 될수록 NPV가 지속적으로 증가하기 때문에 선도 산림경영단지에 대한 투자는 단기적이기보다는 장기적인 관점에서 지속적으로 실시되어야 함을 알 수 있었다. 순천시 선도 산림경영단지는 사업투자에 대한 경제성 이외에도 사업기간 10년 동안 연간 3,000명(180일 기준)을 고용할 수 있기 때문에 일자리 창출 등 지역경제 활성화에도 크게 기여할 것으로 판단된다. This study intended to provide basic data in relation to the establishment of a forest management plan in the future through the economic feasibility analysis on business investment regarding the leading forest management zone in Suncheon. For this, NPV and IRR analyses were performed to obtain indices for economic feasibility analysis. According to results, NPV in the tenth year into the business was estimated at 241.9 million won and IRR, 8.5%, which indicated that the business investment in the leading forest management zone in Suncheon is economically feasible. In addition, NPV is estimated to increase continuously as the business persists and it indicated that the investment in the leading forest management zone shall be made continuously with a long-term perspective rather than for a short term. Apart from the economic feasibility of business investment, the leading forest management zone in Suncheon is expected to make an immense contribution to the revitalization of local economy by creating jobs as it is expected to hire 3,000 people a year (180 days) during the project period which spans ten years.

정부는 안전성이 확보된 청정 산양삼을 생산하여 임업인의 소득증대 및 국민건강 증진에 기여코자 2014년 5개년 계획으로 산양삼 산업육성대책을 수립하였다. 그러나, 중국산 장뇌삼의 수입이 증가할 수 있어, 산양삼 가격하락으로 인한 재배상의 어려움도 예상하고 있다. 따라서, 본 연구에서는 산양삼 재배ㆍ경영상의 문제점을 파악하고 생산 확대 방안을 모색하고자 경상 남도 함양군 소재 산양삼 재배 40농가를 대상으로 현지조사를 실시하였다. 그 결과, 농가 평균 산양삼 조수입은 2,171만원이었으며, 향후 산양삼 재배규모에 대해서는 37농가가 가계소득증대를 위해 확대와 현상유지를 계획하고 있었다. 산양삼 재배가 농가소득증대로 연계되기 위해서는 산양삼을 적정 가격에 상시 판매할 수 있는 공동판매장 설치 확대, 종ㆍ묘 공급체계 확립, 동물과 도난피해를 최소화할 수 있는 방안 마련 등이 필요하다는 결과를 얻을 수 있었다. In 2004, the Korean government established the policy of a 5-year plan to foster the mountain ginseng industry. It is expected to contribute substantial income increase for people engaged in forestry and promote national health by cultivating eco-friendly mountain ginseng. However, we anticipate some difficulties along the way of cultivation due to price decline of mountain ginseng which has derived from the increase in the import of ginseng from China. With seeking the way to expand production, this study has conducted investigations of 40 mountain ginseng farming families in Hamyang, Gyeongsangnam-do. The purpose of this study is to examine the problem in cultivation and management of mountain ginseng. As a result, an average gross income of the mountain ginseng farming family was about 22 million won, and 37 farming families have had a plan to sustain the current scale in cultivation or to enlarge increasing household incomes. We [md that some plans are needed in order to make cultivation of mountain ginseng for the increase of farm household incomes. The research has concluded that it requires expanding the installation of joint sales to sell mountain ginseng at an appropriate price at all times. Also the species and seedling supply system should be designed. Moreover, drawing up the measure to minimize animal damage and theft should be monitored.
