본 연구는 미얀마 바간(Bagan)지역 전통 건축물의 벽체 보수에 사용되는 소석회에 대한 광물학적 특성을 분석하고 바간 지역 문화재 수리 현장과 동일한 방법으로 제조한 석회 플라스터의 물리적 특성을 파악하였다. 미얀마 소석회의 X-선 회절 분석과 열분석 결과 포틀랜다이트(Ca(OH)2)와 수활석(Mg(OH)2)이 주구성광물로 검출되었으며, 이를 통해 석회의 원석으로 백운석(CaMg(CO3)2) 광물의 함량이 높은 탄산염 암석이 사용됐을 것으로 추정된다. 주사전자현미경 분석 결과 미얀마 소석회는 0.5 μm 이상의 불규칙한 형상을 가진 결정들과 소량의 0.1 μm 크기의 판상형 결정들이 응집되어 있고 전체적으로 매끄러운 조직 형태를 관찰할 수 있었는데, 국내에서 건식 소화시킨 소석회와 비교했을 때 결정의 크기나 균일도가 다른 것은 소석회 간 구성광물의 차이와 미얀마 특유의 전통 습식 소화방법에 의한 영향으로 판단된다. 28일 동안 양생한 미얀마 석회 플라스터의 압축강도 값은 평균 1.13 N/mm2이며, bale (Aegle marmelos) 열매의 물 추출액을 첨가한 플라스터 시편의 압축강도 값은 평균 1.03 N/mm2로 측정되었다. 석회는 장기간 탄산화 과정을 거쳐 강도가 발현되는 기경성 재료이므로 향후 28일 이상 장기 양생을 통해 양생기간별 물리적 특성의 변화 양상을 파악할 필요가 있다.

In this study, uncertainty ranges for bias-corrected temperature and precipitation in seven metro-cities were estimated using nine GCM-RCM Matrix, and climate changes were predicted based on the corrected temperature and precipitation. During the present climate (1981-2005), both uncertainties for annual temperature and precipitation and differences in regional uncertainties were reduced by bias correction methods. Model’s systematic errors such as cold bias of surface air temperature and underestimated precipitation during the second-Changma period were improved by a bias correction method. Uncertainties of annual variations for bias corrected temperature and precipitation were also decrease. Furthermore, not only mean values but also extreme values were improved by bias correction methods. During the future climate (2021-2050), differences in temperature and precipitation between two RCP scenarios (RCP4.5/8.5) were not quite large. Temperature had an obvious increasing tendency, while future precipitation did not change significantly compared to present one in terms of mean values. Uncertainties for future biascorrected temperature and precipitation were also reduced. In mid-21st centuries, models prospected that mean temperature increased thus lower extremes associated with cold wave decreased and upper extremes associated with heat wave increased. Models also predicted that variations of future precipitation increased thus the frequency and intensity of extreme precipitation increased.

This paper has identified detailed climate types and their geographical extents in the Republic of Korea using MK (Modified Korean)-PRISM (Parameter-elevation Regression on Independent Slopes Model) 1×1km high-resolution grid climate data and Trewartha climate classification. When considering 60 ASOS (The Automated Synoptic Observing Systems) stations, only four climate types were identified over South Korea. Three climate types, Dca (52%), Doa (28%) and Cfa (18%), were prevalent while Dcb type was only located at Daegwallyeong. When based on a high-resolution grid climate data, six climate types were identified including Dob and E types which were not detected with ASOS stations. High-resolution grid climate data reflected better and detailed geographical characteristics. Areas occupied by Cfa climate types were located along the narrow southern and Jeju coastal areas, dedicating only 6.9% of South Korea. Trewartha climate classification was also applied to 1km×1km RCP scenarios. The most distinct feature of future climate changes based on RCPs was a larger expansion of Cfa and Doa types with a drastic reduction of Dca and Dcb, indicating that a warmer and wetter climate would be prevalent over South Korea in the latter period of this century. Even for RCP2.6, all the coastal areas, some of Seoul metropolitan area, a large part of Daegu and Gwangju metropolitan areas would be classified as Cfa. For RCP8.5, 51.5% of South Korea would be occupied by the Cfas and 25.1% by the Doas, leaving only 23.2% of Dcas.

본 연구의 목적은 동와 조휘진(1729-1797)의 생애와 활동을 밝히는 일이다. 일반적으로 正祖가 남명 조식에게 사제(賜祭)하였던 시기를 남명학 부흥의 시발점으로 일컫는데, 그는 이때 남명학파의 중심인 덕천서원을 대표하는 인물이었다. 따라서 각종 진주 관련 지리지에 그의 이름이 기재되어 있고, 출중한 인물로 많은 인물과 교유하고 있었음을 밝히고 있으나 자세한 연구가 이루어진 바가 아직 없다. 그의 집안은 대대로 함안에 세거하였다. 조선 건국 후 출사를 거부하고 함안에 은거하였던 趙悅, 단종 때의 생육신 가운데 한 사람이었던 趙旅, 임진왜란 때 순사한 趙宗道가 그의 선조이다. 그는 평소 효를 실천함과 동시에 선조의 忠을 드러낸 것 역시 효의 실천으로 보았다. 선조 열 명의 업적을 기록한 『趙氏十忠實錄』은 그 결과물이라 할 수 있다. 아울러 남명학의 전수자로서 덕천서원을 중심으로 유림을 규합하는 역할을 하였다. 그의 문집인 『東窩遺集』에 보이는 창화시 및 만사를 통해 그의 교유범위가 퇴계학파와 중앙의 남인까지 포괄하고 있음을 확인할 수 있다. 기개와 절조를 숭상하고 處士的인 학풍을 견지하던 남명학파의 유풍을 그대로 견지하였던 인물이라 평가할 수 있다.

본 연구의 목적은 유아들의 생활에 기반이 되는 지역 환경을 활용한 프로젝트 과학 활동을 실시하고 유아와 교사에게 주는 의미를 분석하여 과학교육의 실천적 방향을 탐색해보는 것이다. 이를 위해 실행연구 방법을 활용하여 연구자와 교사가 협력하여 D시에 위치한 공립단설유치원 유아 28명을 대상으로 지역 환경을 활용한 프로젝트 과학 활동을 실시하고, 수업녹화영상, 수업일지, 연구일지, 교사 저널을 통해 그 의미를 분석해 보았다. 연구 결과, 지역 환경을 활용한 프로젝트 과학 활동의 의미는 다음과 같다. 지역 환경을 활용한 프로젝트 과학 활동이 유아에게 주는 의미는 ‘공동의 관심사 탄생’, ‘자연스럽게 이어지는 과학적 탐구’, ‘지켜주고 싶은 자연’으로 범주화 되었다. 지역 환경을 활용한 프로젝트 과학 활동이 교사에게 주는 의미는 ‘생활과 교육과정의 통합’, ‘지속적 탐구와 몰입을 이끄는 과학적 탐구과정’, ‘가정과의 연계를 통해 확장된 과학적 탐구’로 범주화 되었다. 결론적으로 유아의 생활을 기반으로 지역 환경을 활용한 프로젝트 과학 활동은 유아의 과학적 탐구와 지역 자연에 대한 긍정적 태도 형성에 도움이 되었으며, 이를 통해 교사는 의미 있는 과학교육의 실천을 경험하는 기회를 가질 수 있었다고 결론지을 수 있다.

다문화가정의 증가와 더불어 다문화학생이 밀집되는 학교가 생겨나게 되고, 이에 따라 학교의 교육과정도 변화가 필요하게 되었다. 이러한 시대적 흐름에 따라 경기도 교육청은 다문화학생이 밀집된 학교를 다문화국제혁신학교로 지정하였다. 본 연구는 다문화국제혁신 학교로 지정된 세 초등학교를 바탕으로 시대적·사회적 요구를 반영하여, 학습자 모두를 위한 교육과정 운영 방향을 탐색하고자 한다. 이를 위해 다문화국제혁신학교로 지정된 세 초등학교의 다문화교육과정을 분석하고, 운영 담당자를 대상으로 심층 면담을 진행하였다. 다문화교육과정 분석을 통해 세 학교 공통적인 내용 요소 및 운영 방법을 추출할 수 있었으며, 운영 담당자와의 심층 면담 자료를 바탕으로 질적연구를 수행하였다. 연구 결과를 바탕으로 정규 교육과정운영이 어려운 다문화밀집지역 학교의 다문화교육과정 운영 방향에 대한 시사점이 아래와 같이 도출되었다. 첫째, 이중언어 수업 교실 운영이다. 한국어가 능숙하지 못한 다문화학생들은 모어를 통한 학습의 기회를 제공받고, 국제화시대에 외국어교육을 강화하기를 희망하는 일반 학생들은 그들의 능력을 신장할 수 있도록 교과를 이중언어로 배우는 것이다. 둘째, 학생 단계에 따른 맞춤형 국어 수업이다. 맞춤형 국어 수업은 다문화학생에게는 한국어를 수준에 맞게 배울 수 있는 기회를 제공하며, 일반학생들은 학력 향상을 도모할 수 있다는 효과를 기대 할 수 있다. 셋째, 다문화통합교육과정 개발 및 수업 자료 보급이다. 기존 교과서를 통합하여 연계성 있고 지속성 있는 다문화통합교육과정을 개발하여 문화이해 교육에서 벗어나 비판적 사고 및 사회 행동적 접근으로 나아갈 수 있도록 교육과정을 개발하는 것이 필요하다. 넷째, 다문화학생 적응 지원을 위한 디딤돌 교실 운영 및 상담 지원이 필요하다. 특별 학급 및 예비 학급에서 일반학급으로 넘어가는 중간 단계에서 다문화학생의 학교생활 적응을 위한 디딤돌 교실이 운영되어야 할 것이며, 한국어 부족 학생 상담을 위한 통역 동반 상담 지원 시스템이 구축되어야 할 것이다. 다섯째, 학생 및 교육과정 운영에 맞는 평가 도구를 개발해야 한다. 이중언어로 진행하는 교과 교육 및 맞춤형 국어 수업을 통한 교육과정 실행에 따른 적합한 평가 방법 및 도구 개발이 요구된다. 여섯째, 국가 및 지역 교육청의 다각적 지원이 요구된다. 본 연구는 다문화학생의 비율 증가로 정규 교육과정 운영이 어려운 다문화밀집지역의 학교에서 모든 학생의 성장을 위해 교육과정의 구조적 변화를 시도하고 그 방향성을 탐색하였다는 점에서 의의를 갖는다.

Numerical experiments were carried out to investigate the effect of data assimilation of observational data on weather and PM (particulate matter) prediction. Observational data applied to numerical experiment are aircraft observation, satellite observation, upper level observation, and AWS (automatic weather system) data. In the case of grid nudging, the prediction performance of the meteorological field is largely improved compared with the case without data assimilations because the overall pressure distribution can be changed. So grid nudging effect can be significant when synoptic weather pattern strongly affects Korean Peninsula. Predictability of meteorological factors can be expected to improve through a number of observational data assimilation, but data assimilation by single data often occurred to be less predictive than without data assimilation. Variation of air pressure due to observation nudging with high prediction efficiency can improve prediction accuracy of whole model domain. However, in areas with complex terrain such as the eastern part of the Korean peninsula, the improvement due to grid nudging were only limited. In such cases, it would be more effective to aggregate assimilated data.

In this study, we typified the project for revitalizing the rural area through text analysis using news data, and analyzed the main direction and characteristics of the project. In order to examine the factors emphasized among the issues related to the revitalization of rural areas, we used news data related to 'tourism' and 'livelihood', which are the main keyword of the project to promote rural areas. In the analysis, text mining techniques were used. Topic modeling was conducted on LDA techniques for major projects in 'tourism' and 'livelihood' keyword. Based on this, this study typified the projects that are carried out for the activation of rural areas by topic. As a result of the analysis, it was fount that the topics included in the project were distributed in 11 sub-types(Tourism Promotion, Regional Specialization, Local Festival, Development of Regional Scale, Urban and Rural Exchange, Agricultural Support, Community Forest Management, Improve the Settlement Environment, General Welfare Service, Low Class Support, Others). The characteristics of the rural revitalization projects were examined, and it was confirmed that domestic projects were carried out by tourism-oriented projects. To summarize, the government is making projects to revitalize rural areas through related ministries. Within the structure where the project is spreading to the region, a lot of projects are being carried out. It is understood that the tourism and welfare oriented projects are being carried out in the revitalization project of the domestic rural area. Therefore, in order to achieve the goal of rural revitalization, it is believed that it will be effective to carry out a balanced project to improve the settlement environment of the residents.

The nonpoint pollution source (NPS) is irregular in the amount of generated and runoff. About 70% of the water pollution sources in Korea are NPS. Most of the rural areas are small towns with less than 50 families. This is where sewerage supply is poor. This is where the domestic swage of the house flows directly into the small stream. This study investigated the amount and concentration of domestic swage. And investigated NPS for public officials. We have suggested an improvement plan here. Local government officials lack the concept of NPS. Rural residents also do not know about NPS. Therefore, we proposed NPS public relations and education linked to public administration. This is an extension of the national budget and interest. The domestic swage is discharged at about 272 liters per day in a house. We proposed the introduction of small facilities. If the capacity remains, it is suggested to link to cattle shed, pigsty and so on. The BOD, COD, TN, TP, and SS concentrations were all high. This suggested a reduction in concentration in combination with natural water. Finally, NPS facilities were proposed to be put into rural areas. And it was determined that continuous monitoring was necessary. The results of this study were expected to be applied to NPS management.

This study analyzes the effect of the level of satisfaction with the living environment of rural people on migration. The analysis data were used by the Rural Development Administration for the survey of welfare systems for farmers and fishermen in 2017, and samples of 3,776 were used for the analysis. The analysis variables were divided into a group of migrants, a group of permanent residents, and a group of decision-keeping, and the level of satisfaction with the living environment of each of the 10 rural areas was used as an independent variable. According to the analysis results, the basic living base and safety of rural residents were having a positive effect. The results show that the projects for developing rural areas, which increase the basic living base, are making substantial contributions to preventing the breakaway of the rural population. Safety has been neglected in the area of rural planning, but if the level of discontent is not enough, it has had the greatest impact on the livelihoods of rural residents. Welfare and cultural leisure set the main demand level for welfare and cultural leisure to the elderly and vulnerable classes, and interpret it as a result of weakened defense against stress from relocation of residence, difficulty of migration due to low income levels, and migration. Therefore, the paradoxical analysis results could be interpreted as showing that measures to increase the satisfaction of the people on welfare and cultural leisure should be taken.

Waste management in Jeju Province, Korea, has recently emerged as an urgent problem. The increasing waste discharge requires more landfills but, since it is an island, the available land is restricted. Accordingly, an efficient waste management urgently requires environmentally sustainable policies. In this article, the waste discharge characteristics (such as the amount of waste, its composition, etc.) of Jeju Province have been compared with those in the rest of Korea. The current industrial waste management of two cities on the Island, Jeju City and Seogwipo City, has been also analyzed to suggest policies for an efficient management. The local government’s endeavor to enhance environmental awareness of the community has been known to reduce the private cost of policy compliance, and have individuals recognize the results of their policy compliance. Policies to achieve the above are then proposed.

Background: The ginsenosides Rb1 (G-Rb1) and Rg1 (G-Rg1) are used as marker compounds, and are the principal bioactive compounds assessed in the quality control of white ginseng. This study was conducted to analyze white ginseng samples of different and to obtain useful data for the quality control of white ginseng. Methods and Results: The variation in the content of G-Rb1 and G-Rg1 was evaluated among 35 samples of 4-, 5-, and 6-year-old white ginseng. The content of both G-Rb1 and G-Rg1 did not significantly differ among ages, and the relative ratio of the maximum to the minimum content of these within ginseng of the same ages was more than two. However, the ratio of G-Rb1 to G-Rg1 content in the 5- and 6-year-old ginseng was significantly higher than that in the 4-year-old one. According to the ‘Ginseng industrial act’, the standard (w/w, %) minimum G-Rg1 and G-Rb1 content is 0.10% and 0.20% or more, respectively. Among the 35 samples examined, the content of G-Rg1 was found to be 0.124 - 0.399% with none being less than the standard level, while that of G-Rb1, was 0.147 - 0.595%, with 4 samples (11.4%) failing to meet the standard levels. The content of G-Rg1 and G-Rb1 did not show a constant relationship with the size of ginseng. Conclusions: In our study, the content of both G-Rg1 and G-Rb1 varied widely, and there was no significant difference among cultivation ages. The results of the present study might provide useful information for the quality control of raw ginseng and processed white ginseng using marker compound.

Background : Wild-simulated ginseng (WSG, Panax ginseng C. A. Meyer) in Korea which depends on an artificial forest growth method. Methods and Results : WSG samples were collected from 8 different regions in Korea in October, 2017, and these were analyzed by ultraperformance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF MS) using optimized analytical methods to compare the metabolite patterns to cultivated regions. Furthermore, their metabolite compositions differed according to individual plant samples. The metabolite profiling data were processed by multi-variate statistical analyses such as PCA and PLS-DA to determine the differences among geographical origins. To identify significant metabolites according to regional variances of WSG, more sophisticated multi-variate statistical analyses such as metabolite selection should be performed. Conclusion : This metabolomics approach can also be applied to evaluate the overall quality of WSG, as well as to discriminate the cultivars for the medicinal plant industry.

Background : This study examines the main growth characteristics, physiological stress, or diseases damage for 3 and 4-years-old ginseng in the new lines cultivated in Gyeonggi for development of new lines of Ginseng. Methods and Results : Eumseong 13, 14 and 15, which are two-years-old seedling in the new line ginseng were transplanted in 7 lines × 9 rows (70 plants)/1.62㎡ in 2015 along with Gumpoong and Yeonpoong as the control lines while Eumseong 16 and 17 as well as Chunpoong as the control line were transplanted in the same way in 2016. The ginseng shading was installed with the front post of 170 ㎝ high and the rear post of 100 ㎝ high using the rear line while as the sun blocking material, the aluminum shade plate was used. As for the new growth lines of 3 and 4-years ginseng in the new growth line, the aerial parts of the ginseng and underground part of ginseng were examined. In addition, the physiological stress such as the leaf discoloration, rusty root and root rot as well as the resistance against the disease were examined. It was found out that as for the aerial parts of 3-years-old ginseng in test line, Eumseong 16 and 17 were better in the growth than the control lines were while in 4 years old ginseng, Eumseong 13 and 14 were better in the growth than Gumpoong as the control line was. As for the root weight of the 4-years-old ginseng for the underground part, there was no significant difference compared with control line while in 3-years-old ginseng, Eumseong 16 and 17 were heavier. The leaf discoloration did not happen to both 3 and 4-years-old ginseng. As for the root rot, 3-years-old Eumseong 16 and 17 suffered less root rot in the same way as for the control line. 4-years-old Eumseong 14 and 15 had less root rot in the same way as for the control line. 3-years-old Eumseong 16 and 17 have less rusty root in the same way as the control line while as for 4-years-old ginseng, Eumseong 13, 14 and 15 showed a lot of rusty roots in the same way as the control line. Conclusion : Finally, considering the growth characteristics, physiological stress and root rusty of the aerial parts and underground parts of the ginseng, we selected Eumseong 16 and 17 as the excellent lines for 3-years-old ginseng.

Background : Atractylodes macrocephala is a perennial herbaceous plant belonging to the family Asteraceae and should be cultivated in field soils with good water dripping due to plant characteristics. However, cultivating farmers mainly have recently been cultivated in paddy soil due to their regional characteristics, which causes the decrease in yield due to poor drainage. Therefore, this study was carried out to investigate the cultivation in high ridge and subsoil breaking effect for stable paddy soils cultivation technology of A. macrocephala. Methods and Results : Soil was paddy soils in the fall of 2017, and the pH (1 : 5) was 6.61 ± 0.15 as a result of chemical and physical properties. EC was 0.49 ± 0.05 dS/m, and organic matter content was 28.69 ± 69 g/㎏ and effective phosphoric acid was 306 ± 17.8 ㎎/㎏. As a result of the soil layering survey, the surface layer was 0 - 26 ㎝ deep as paddy soil mounded with sandy loam in the past. In the surface layer, there was a light layer after 17 ㎝ depth, and volume density was 1.71 ± 1.3 g/㎤. The porosity of the plow pan was 33.41 ± 2.34%. The cultivation methods were cultivation in high ridge (30 ㎝ or more) and level row (10 ㎝ or less) at 2 levels and 3 repetitions. In subsoil breaking, the depth of the plow pan was increased from 17.1 ± 0.5 ㎝ before treatment to 31.1 ± 3.6 ㎝ after treatment and the hardness was 24.8 ± 1.5 ㎜. In the case of rotary plowing, the depth of the plow pan was 17.1 ± 1.9 ㎝ before treatment and 26 ± 2.4 ㎝ after treatment and the hardness was 25.8 ± 2.9 ㎜. The medium growth characteristics of A. macrocephala per treatment showed the tendency of increase in plant length, culm length, number of nodes, number of leaves, and fresh weight in level row cultivation after subsoil breaking. Root growth of cultivation in high ridge after subsoil breaking tended to be good with rhizome weight of 11.6 g per hill. The survival percentages were 98.8 - 100% and the bolting rate was 93.4 - 96.2% Conclusion : In cultivation in high ridge after subsoil breaking in the paddy field of Gangwon area, the decrease of yield of A. macrocephala due to drainage was expected to be alleviated, but final conclusion should be drawn after analyzing soil temperature and soil moisture data.

Background : Ginseng (Panax ginseng C. A. Meyer) is a multi-year-cultivated plant that causes many insects and disease damage during the growing season. The Ginseng Rain-sheltered Shade House is one of the efficient cultivation techniques as reducing the damages caused by natural disaster such as blight, high temperature & humidity, dry, and heavy rain & snow. This study was conducted to investigate the growth characteristics of 4-years-old ginseng using rain-sheltered shade house suitable shading materials for the Gyeongsangbuk-do. Methods and Results : The rain-sheltered shade house shading materials were PE film with layered polyethylene net 90%, Light diffusion film with layered polyethylene net 75%, blue-white duplicated film. In order to determine proper shading materials of the rain-sheltered shade house, ginseng growth characteristics such as plant length, stem diameter, leaf length, root length and root diameter were investigated at 4-years-old ginseng. As a result, the evaluations of aerial part growth by measurements were good in the following order: PE film + polyethylene net 90%, Blue-white duplicated film and light diffusion film + polyethylene net 75%. The evaluations of root weight by measurements were heavy in the following order: Blue-white duplicated film, PE film + polyethylene net 90% and light diffusion film + polyethylene net 75%. The net photosynthetic rate was higher in blue-white duplicated film than other shading materials treatments during growth season including summer high-temperature period. Conclusion : In the 4-years-old ginseng cultivation in Gyeongsangbuk-do using the rain-sheltered shade house, aerial part growth in PE film + polyethylene net 90% was better than other shading materials. In addition, root weight in Blue-white duplicated film was heavier than other shading materials. It will be possible to know which shading material is the most suitable for Gyeongsangbuk-do area after further growth.

Background : The cultivation area of Rehmannia glutinosa Liboschitz is 156 ㏊ ('16), which is one of my representative medicinal crops. However, since it grows by roots, the damage of the repeated cultivation and the degeneration of the seedstock are increasing. To solve these problems, we are developing new varieties every year by testing the regional adaptability of high quality system. In recent years, as the quality and quantity of new varieties have been proven to increase, the need for continuous development of excellent varieties is increasing. Methods and Results : The test material used a jihwang-1 as standard variety, the system was planted in 3-year (RGES 20), 2-year (RGES 21, 22, 23) and 3-year (RGES 24, 25). The root lengths were cut at intervals of about 2 to 3 ㎝ and immersed for 20 minutes in a fludioxonil suspension concentrate (1,000-fold dilution) and shaded for 1 day. Sowing was planted on April 30th, and planting interval was 30 ㎝ × 15 ㎝. Growth investigation was carried out on the overground growing (plant length, leaf length, leaf number, plant type, etc) and degree of generation of pests. As a result of the growth investigation, the third year RGES 20, the second year RGES 22, and the first year RGES 25 were excellent. RGES 20 was upright type and superior in overground growing, RGES 22 had strong pest resistance. RGES 25 was characterized by strong at high temperature, but growth is not as good as other high quality system. Conclusion : Recently, the difficulty of cultivation of zucchini has been increasing due to abnormal weather. Especially in this year, high temperature of 35℃ or more continued for about 30 days, and the need to cultivate varieties resistant to high temperatures is increasing. Therefore, it is expected that RGES 25 can be registered as a promising strain that is resistant to high temperature if the yield is corrected.

Background : For cultivation of varieties of ginseng, the pure line selection method, which is to select the best among those cultivated in farms for pedigree breeding, replicated yield trials and regional adaptation trials before registering as a new variety, is widely used. Although there are 25 registered varieties of ginseng in Korea, the quality of ginseng is declining together with the amount of harvest being decreased by 15 - 20% due to the heat injuries and diseases from the warming & abnormal climate. Thus, the needs for development of disaster-resistant varieties with better chances of surviving through high temperature, salts and disease are increasing. Therefore, this study is to cultivate disaster-resistant varieties among those selected for their disaster tolerance and salt tolerance through regional adaptation trials. Methods and Results : As a result of examining the growth characteristics of the selected 2-6-years-old varieties used in the study, among the 6-years-old crops, Eumseong 9 and Eumseong 10 showed superior growth in aboveground parts, Eumseong 10 showed superior growth in underground parts, among the 5-years-old crops, Eumseong 15 showed superior growth in both above and below aerial parts, and among the 4-years-old crops, Eumseong 9 and Eumseong 16 showed superior growth while the growth in the underground parts were satisfactory in the order of Eumseong 16 > Eumseong 10 > Eumseong 12 > Eumseong 9. Among the 3-years-old crops, the most superior growth in both above and below aerial parts was observed in Goryeo 2 with the weight of the underground part, in the 2-years-old crops, Eumseong 26 showed the most superior growth in both above-ground and underground parts. Conclusion : Based on the above results, Eumseong 10 among the 6-year-old crops, Eumseong 15 among the 5-years-old crops, Eumseong 9 & Eumseong 16 among the 4-years-old crops, Goryeo 2 among the 3-years-old crops and Eumseon 26 among the 2-years-old crops showed the most superior growth among the selected varieties. The growth characteristics of both above and below aerial parts in each year will continuously be monitored.

Background : Panax ginseng C. A. meyer is currently cultivated throughout the Korea Peninsula except for Jeju Island. We divided into 3 sectors according to latitude, north, middle, and south, and compared ginseng growth and environmental factors. Methods and Results : We surveyed 11 farms, and while temperature, plant density, sunshade material, and soil properties were varied between the farms, most north part used sunshade film and transfer-seeding, and middle-south and south part used sunshade net, and direct-seeding. From 1st to 10th of June, 2018, the temperature inside of sunshade of each farm which ranged 20.5 - 24.5℃ did not concerted with the local meteorological air temperature nor latitude. The average plant length was 66.0 ± 8.1 with a significant difference between local farms (p < 0.001). Plant length showed high correlation with stem length, stem diameter, leaf length, and leaf width, but not with chlorophyll content, thus plant length was used to compare the effects of environmental factors on plant growth. The temperature had negative correlations between plant length (r = -0.396, p = 0.056) and stem length (r = -0.420, p = 0.041), but not with others. When local farms grouped into 3 sectors, the temperature inside sunshade was lowest in south than others, and stem diameter, leaf length, and leaf width of north sector were higher than other sectors. Conclusion : The temperature of local farm might affected by micro environment such as sunshade and geometrical properties, and partially devote on the growth difference between the local farms.

북한은 수력발전이 전체 발전량의 약 63%를 차지할 만큼 비중이 높고, 지리적으로 수력발전 개발에 많은 이점을 가지고 있다. 본 연구에서는 33 개의 북한 댐개발 가능지점에 대해 DEM자료를 이용하여 유역분석 및 저수량을 산정하고, MWSWAT 모델을 이용한 30년간의 장기유출 분석 결과를 적용하여 연간가능발생전력량을 추정하였다. 33개 지점의 연간가능발생전력량은 현재 북한 수력발전량의 약 28% 수준으로 평가되었다. 또한 도별 공업지구 규모를 추정하고, 장래 인구 변동을 전망하여 도별 댐개발 우선순위를 선정하고, 저수량과 연간가능발생전력량을 기초로 도내 댐 개발 우선선위를 선정하였다. 도별 우선순위는 평안남도, 함경남도, 함경북도, 황해북도, 평안북도, 자강도, 량강도, 황해남도, 강원도 순으로 나타 났다. 본 연구의 결과는 북한지역의 수력발전댐 개발사업의 진출을 위한 초기 검토 자료로 활용이 가능할 것으로 판단된다.
