논토양에서 적응하는 품종 선발과 재배기술을 개발하기 위해 배수등급이 다른 논토양(배수 불량지와 배수 약간불량지)에서 천풍, 연풍, 황숙종, 자경종 등 4 품종을 사용하여 2년생 인삼의 생육특성 및 수량성과 뿌리의 진세노사이드 함량을 조사한 결과는 다음과 같다. 1. 배수등급에 따라 지상부 생존율과 황증 발생율은 뚜렷한 차이를 보여 배수불량지에서는 지상부 생존율이 저하되고 황증 발생율이 증가하였는데, 배수불량지에서 황숙종은 지상부 생존율이 가장 높고 황증 발생율이 가장 낮았으며, 연풍은 지상부 생존율이 가장 낮고 황증 발생율이 가장 높았다. 2. 배수불량지에서는 배수약간불량지에 비해 지상부가 일찍 고사된 관계로 주당 근중이 작고 수량성도 뚜렷이 감소되었는데, 배수불량지에서의 수량성은 자경종 > 천풍 > 연풍 > 황숙종 순으로 자경종과 천풍의 수량성이 높았으며, 배수약간불량지에는 천풍 > 연풍 > 자경종 > 황숙종 순으로 천풍과 연풍의 수량성이 높았다. 3. 적변율은 배수등급보다는 품종 간에 더 큰 차이를 보였는데, 천풍과 자경종의 적변율은 비교적 작은 반면 연풍과 황숙종은 매우 큰 특징을 보였다. 4. 근 비대가 불량했던 배수불량지는 배수약간불량지보다 진세노사이드 함량이 증가되었는데, 배수불량지에서 품종별 총 진세노사이드 함량은 연풍 > 천풍 > 자경종 > 황숙종 순이었고 배수약간불량지에서는 연풍 > 자경종 > 천풍 > 황숙종 순으로 배수조건에 관계없이 연풍이 가장 높고 황숙종이 가장 낮았으며, 천풍과 자경종은 서로 비슷하였다.

To selection of optimal shading material, two-year-old ginseng (Panax ginseng C. A. Meyer) of new cultivar, 'Cheonpoong' (CP), and native species 'Hwangsookjong' (HS) were cultured under three kinds of shading materials such as three-layered blue and a one-layered black PE (polyethylene) net (TBSB), blue PE sheet (BS), and aluminium coated PE sheet (AS) in imperfectly drained paddy soil. Growth characteristics, yield and ginsenoside contents were investigated under three shading materials. Yield and ginsenoside contents of ginseng were distinctly affected by intensity and quality of sunlight penetrated through shading materials. Light transmission ratio, air and soil temperature according to shading materials were higher in order of BS, AS, and TBSB. However, ratio of aerial phase and porosity of the soil were higher in order of AS, BS, and TBSB, respectively. There was no significantly difference in the ratio of rusty colored root by shading materials. CP showed higher stem length, leaf area, and root weight than that of HS, while the former showed distinctly lower discolored leaf ratio than that the other. Eight kinds of ginsenosides content of CP were higher than that of HS in Rg1, Re, Rf, Rb1 and Rc except Rg2, Rb2, and Rb3. Total ginsenoside contents of CP was distinctly higher than that of HS. Total ginsenoside contents as affected by shading materials was higher in order of BS, TBSB, and AS in CP, while TBSB, BS, and AS in HS.

A new peanut variety “eonan”(Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was developed from the cross between the erect short stem cultivar “P9128” and the high-yielding cultivar “aekwang” “eanan”which is Virginia plant type has 18 branch number per plant with early maturing and long-ellipse shaped large kernel. Each pod has two grains with brown testa and 100 seed weight was 87 g in the regional yield trials (RYT). Especially this variety has resistance to lodging owing to short stem. The free sugar and tannin content of fresh peanut are 3.7% and 0.48%, respectively, similar to check variety. In the regional yield trials “eonan”was outyielded than check variety by 14% with 8.59 MT/ha for fresh pod and by 7% with 3.75 MT/ha for grain.

A new peanut variety “ungsan”(Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was derived from a cross between a short stem cultivar “atonoka”and a high-yielding local cultivar “echeon” “ungsan”is the Virginia plant type. It has 18 branches per plant and 40 cm of main stem height. Each pod with long-ellipse shaped large kernel has two grains with light-brown testa and 100 seed weight was 95g in the regional yield trials (RYT). “ungsan”showed more resistant to web blotch compared with check variety. In the regional yield trials “ungsan”was outyielded in grain yield to the check variety by 16% with 4.45 MT/ha for grain.

A new peanut variety “harmpyeong”(Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was developed from the cross between the high-yielding cultivar “hindaekwang”and the very short stem cultivar “CGV94216” This Virginia plant typed “harmpyeong”has 33 cm stem height and 18 branch number Each pod with ellipse-shaped large kernel has two grains with brown testa and 100 seed weight was 88 g in the regional yield trials (RYT). This variety also showed more resistant to web blotch compared with check one. Especially it has resistance to lodging until harvesting owing to short stem. In the regional yield trials “harmpyeong”was outyielded than check variety by 13% with 4.35 MT/ha for grain.

This research aimed to grasp the recognition of the amenity of the university students residing in Gyo-dong residential area in Gangneung city, the local residents residing in Daehag-ro which is near Jungang-ro in downtown and the public servants related to city development in Gangneung city office and thereby propose a plan to improve the amenity of Gangneung city. Based on the result of the research, the university student group around Gyo-dong residential area mostly recognized the amenity and the local residents around Daehag-ro showed insufficient recognition of the amenity and some of related public servants were found to be ignorant of the term amenity. Also, the priorities of amenity indexes identified from these 3 groups commonly showed aliveness requiring green lands and watercourses on top but 2nd priority of each group tended to be different from each other. Through the research result as above, we would like to propose the plan to improve as follows. First, the recognition of the concept of amenity is necessary. Second, green lands and watercourses that were selected by all of the 3 groups as ranking no. 1 should be secured. Third, the value of amenity resources should be evaluated. Gangneung city is a city where mountains and the sea are harmonized together granting abundant god blessed natural resources. But if Gangneung city would imprudently reclaims the excellent god blessed natural environment under the good title of city and housing lands development, its ranking in city competitiveness evaluations will be expected to continue descending. Therefore, as proposed in this research, the thing that has to be implemented with first priority for amenity Gangneung city is the execution of amenity policy to secure the identity of Gangneung city and the aspect of regulations or systems should also be pursued together with the policy.

본 논문에서는 기존 현수교의 정밀측량을 효과적으로 대체할 목적으로 비용과 인력의 소요가 적은 고해상도 디지털 카메라를 이용한 화상변위측정기법을 제시하고 이를 자동화 할 수 있는 프로그램을 개발하였다. 사진의 분할매수에 따른 측정의 정밀도를 고찰하기 위하여 구조물 전체를 5장, 13장, 19장으로 분할 촬영하였고 실제 공용중인 현수교를 대상으로 측정결과를 비교하였다. 개발된 화상처리기법을 이용한 측정결과는 실제 현수교의 정밀형상 측량결과와 비교적 잘 일치하였으며 측정에 소요된 비용과 시간이 매우 절감되는 것으로 나타났다. 본 연구에서 개발된 측정기법은 렌즈의 왜곡현상 보정알고리즘을 개선하고 프로그램의 자동화 비율을 높인다면 다양한 구조물에 적용될 수 있을 것으로 판단된다.

Recently, many researches on the biomass of the agricultural and livestock wastes are being conducted in several respects. The use of biomass is of benefit to the curtailment of oil import, environmental pollution decrease, global warming mitigation and so on. And, in the agricultural sphere, making use of agricultural byproducts can contribute to the revitalization of the agricultural industry and rural community. In other words, making new products or energy by using biomass have a possibility to be developed as a new industry. The industry can create new businesses and job opportunities for rural dwellers. Also, major 3 positive effects of market formation for the agricultural wastes, increase of the idle land use and creation of the new business are expected. However, the use of biomass may be difficult to secure a proper right as a market good in the autonomic market economy. It is necessary to establish or amend related laws or systematic tools for the revitalization of the biomass use. Also, it is required for the government to bear partial costs of the facilities and others in the beginning stage.

Crop inputs in excess of the yield potential of the soil type reduce profitability and increase pollution problems from leaching and runoff. Inaccurate fertilizer and pesticide application can also result in profit loss. Current farming practices plan only for the dominate soil in the field. A government-supported program titled “Pilot village project for the environment-friendly agriculture” was proceeded from 1999 to 2001 to tackle the problems with which our agriculture is faced by introducing IPM, INM and others. The objective of this study is to consider the potential input savings of agricultural chemicals and economic feasibility of the project compared with the conventional farming. The results of the analysis indicate the followings: (1) organic or no-pesticide farming size was increased from 9% in 1999 to 20% in 2001; (2) crop yield was a little bit lower than that of the conventional farming, but the sale price, gross income and income of the pilot village were 6%, 10% and 9% higher than that of the conventional farming, respectively ; and (3) fertilizer and pesticide use also showed decreasing trend gradually.

Recently, together with consumers’ increasing concerns on food safety and environmental issues, there is increasing demand on the environmentally friendly agricultural products such as organic products. At present, Japan, as a biggest net importing country of the agricultural products, is a market of the international-scale in the organic product marketing. Also, it is expected that the possibility of market expansion in the future is very high. According to the 2000 agricultural census in Japan, the number of the environment-friendly agricultural farmers were 501.556 householders. This number is about 145 percent higher than that of the 1996 results of 204,600 householders. Organic products in Japan were mainly marketed through the producer and consumer cooperation, producers" cooperation, specialized marketing company etc. However, along with the department store, big supermarket and others" participation in the market recently, the marketing channels are diversified. As of October 1999, market sales of the organic products were estimated about 350 billion yen. It is expected that organic certification system, organic products import, resturant industry scale and others will be more influential factors on the market expansion of the organic products in the future.
