This study aims at the exploration of usefulness of traditional knowledge reflected in the place names. This study is useful and pragmatic for the establishment of disaster prevention measures from the analyses of disaster database, which shows the regional distribution and historical changes of disaster characteristics through history. The construction and categorization of disaster-related place names are based on historical maps and literatures on place names. One hundred twenty eight disaster-related place terminologies are selected based on disaster causes and possibilities. Design of field structures and category codes for the disaster-related place names has been proposed and the construction of disaster-related place names from the six sources has been completed.

우리나라에서 발생하는 기상 재해 현상은 주로 태풍, 집중호우, 장마 등 인명 및 경제적인 피해가 크며, 단기간에 국지적으로 나타난다. 현재 재해 감시 및 예보는 주로 종관기상관측체계를 이용하고 있다. 하지만, 우리나라의 복잡한 지형, 인구 밀집 지형, 관측 시기가 일정하지 않은 지형과 같은 조건에서 미계측 자료 및 지역이 다수 존재 때문에 강수의 공간 분포와 강도에 대한 정밀한 정보를 제공하지 못하는 실정이다. 최근 광범위한 관측영역과 공간 분해능의 개선, 자료추출 알고리즘의 개발로 전세계적으로 위성영상 기반 기상관측 자료의 활용성이 증대되고 있다. 본 연구에서는 한반도 지역의 지상 관측데이터와 전지구 격자형 위성 강우자료를 비교하여 한반도의 적용성을 분석하고자 한다. 다양한 위성영상 기반 기상자료인 Climate Hazards Groups InfraRed Precipitation with Station (CHIRPS), Precipitation Estimation From Remotely Sensed Information Using Artificial Neural Networks-Climate Data Record (PERSIANN-CDR), Global Precipitation Climatology Centre (GPCC), Precipitation Estimation From Remotely Sensed Information Using Artificial Neural Networks-Cloud Classification System (PERSIANN-CCS) 4개의 강우위성영상을 수집하여, 1991년부터 2020년까지 30년 데이터를 활용하였다. 강수량 변동성 비교를 위하여 기상청의 종관기상관측장비 (Automated Synoptic Observation System, ASOS), 자동기상관측시설 (Automatic Weather System, AWS) 데이터와 상관 분석을 수행하고, 강우위성영상의 국내 적합성을 판단하고자 한다.

This study was carried out to develop new hybrid zoysiagrass cultivar 'Seah' (The application no. for cultivar protection : 2014-22). Native zoysiagrasses were collected from south-west seaside of Korea from 2010 to 2011. Artificial crossing was conducted to develop F1 hybrid between Z2011 (Z. sinica) and NM1 (Z. matrella) at plastic house in 2011. Among the progenies, 'Seah' showed fine leaf texture and high shoot density from the space planting plots at field. 'Seah' showed genetically light green color, with fine leaf with 1.8mm and height to the lowest leaf blade was 1.94 cm. Ground coverage rate was slower than medium leaf zoysiagrass (Jung-gi), but plant height of 7.1 cm was the lowest among the compared zoysiagrasses and height to lowest leaf of 1.94 cm was lower than most zoysiagrass, which may allow low mowing height.

The aquatic insect collected at six areas (each 2 for mountain area, plain field, and urban area) from 2009 to 2011 were classified to analyze the distribution and diversity of species. Frequency (number of aquatic insect: N), number of species (S), similarity index (C), richness index (R1, R2), variety index (V1, V2), evenness index (E1, E2, E3, E4, E5), and dominance index (D1) were investigated. Total N and S were 143 and 84, respectively. C matrix of 153 combinations was constructed with the average of 0.542. The average C of 3 years (0.659) was 9.9% P, more higher than the average C of 6 areas (0.560). The average values of the index of 18 plots were 2.28, 0.17, 1.24, 1.08, 0.07, 0.06, 0.01, 0.87, 0.31, 0.93 for R1, R2, V1, V2, E1, E2, E3, E4, E5, D1, respectively. The order in the coefficient of variation (CV) of the indicator for 18 plots was N (70.0%) > E3 (54.9%) > E1 (49.6%) > R2 (40.5%) > S (35.3%) > R1 (33.7%) > E2 (28.4%) > E5 (15.9%) > V1 (11.1%) > E4 (6.3%) > V2 (5.1%) > D1 (4.8%). The correlation matrix with 66 combinations between the indexes was constructed with statistical significance for 33 combinations. However, R1, V1, E2 and D1 were the proper indexes to represent species diversity of aquatic insect based on the correlation matrix and the theory of statistical independence. The richness index was highest in mountain, variety index in urban area, and evenness index in plain field. However, the dominance index was lowest in urban area.

590 strains of Rhizobia were isolated from root nodules of the legumes collected at 223 sites in Korea. According to their host specificities they were classified into R. japonicum(218 strains), R. phaseoli(101 strains), R. trifolii(97 strains), R. meliloti(4 strains), R. leguminosarium(1 strain), Rhizobium species(101 strains), and unidentified species(159 strains). 3 potent strains R-138, R-168, and R-214 of R. japonicum have been selected based on the infectivity to soybean cultivar and effeciency of nitrogen fixation. It was observed that the fast-growing strains of R. japonicum contained 1 to 4 plasmids of M.W. of 35-300 Md. However, plasmids were hardly detected for the slow-growing strains.

Essential oil components were analysed in forty seven individual plants of Elsholtzia splendens collected from eight different regions in Korea to identify their chemotypes. Major oil components of chemotype 1 was dihydrotagentone (75%) and naginataketone and elsholtziaketone were not detected at all. Chemotype 2 was naginataketone (NK) type which content was more than 60%. Chemotype 3 had more than 60% of elsholtziaketone (EK) as major volatile oil. EK type and NK type plants selected were maintained stably in their progenies after seed generation. Naginatketone and elsholtziaketone had functional properties such as antioxidation and antibacteria.

Ligusticum chuanxiong Hort. is one of the most important root-using medicinal crops in Korea. A new variety 'Sinto' (Suwon 2) was developed from the population of Muju local through phenotyptic restricted mass selection at National Crop Experiment Station, RDA. in 2001. The average yield of this variety was about 2,260 kg/ha in RYT at three location from 1999 to 2001 which were about 20% higher than that of Pyeongchang local. Sinto showed a strong resistance to powdery mildew. This variety may be well adaptable to mountainous mid-southern areas in Korean peninsula.

A survey was carried out on the larval anilsakids in anchovies (Engrnuyis jnponica) which were caught from April to .lune in 1993 at the southern and eastern sea in Korea. Anisakids in anchovies were morphological classified into Anisakis type I and II and Contracaecum type B and C, after fixation in 70% alcohol and clearing in lactophenol. A examined. The infection rates showed no relation with length of the anchovies. The numbers of anisakids by organs of anchovies were 96 (56.1%) from the muscle, 65 (38.0%) from the omentum, 7 (4.1%) from the intestine, 2 (1.7%) from the stomach and 1 (0.6%) from the testis. Infection rates of anchovies with anisakids by localities were 5.1% at Taebyon, 8.0% at Sokcho and 9.2% at Chungmu. The larval uisikids in anchovies may infect humans who often eat raw anchovies.

물봉선속(Impatiens L.)은 일년생 또는 다년생 초본으로 우리나라에 5-7종이 분포한다. 물봉선의 화장품용 항산화제 및 천연 방부제로서의 유용성이 밝혀졌으며, 최근 항염, 항산화 등 생리활성에 대한 연구가 국내 자생하는 물봉선 및 노랑물봉선을 대상으로 수행된 바 있으나 이하 분류군에 대한 연구는 미비한 실정이다. 본 연구에서는 국내 자생하는 물봉선속 분류군들의 항산화활성과 생리 활성물질의 함량을 분석하고 지역 간 분류군별 차이를 확인하고자 하였다. 따라서 국내 자생하는 물봉선속 분류군들의 항산화활성을 검정하기 위하여 DPPH, ABTS, TPC, TFC 4가지 방법을 이용하여 분석하였다. 국내 자생하는 물봉선속 5분류군 가야물봉선(Impatiens atrosanguinea (Nakai) B.U.Oh & Y.P.Hong), 노랑물봉선(Impatiens noli-tangere L), 물봉선(Impatiens textorii Miq), 미색물봉선(Impatiens noli-tangere var. pallescens Nakai), 처진물봉선(Impatiens furcillata Hemsl)이 12개 지역에서 수집되었으며, 잎 추출물(70% 에탄올)에 대해 분석되었다. 물봉선속 분류군들의 잎 추출물의 DPPH 라디칼 소거 활성 검정 결과 가야물봉선(4.91 ± 3.00 mgAAE/g)이 가장 높았고 처진물봉선(1.77 ± 0.55 mgAAE/g)이 가장 낮았으며, ABTS의 경우 가야물봉선(3.14 ± 1.35 mgAAE/g)로 가장 높았고 미색물봉선(1.87 ± 0.16 mgAAE/g)이 가장 낮았다. TPC의 경우 미색물봉선(5.48 ± 1.05 ugGAE)이 가장 높았고 노랑물봉선(2.78 ± 1.98 ugGAE)이 가장 낮았으며, TFC의 경우 물봉선(0.70 ± 0.20 ugGAE/g)이 가장 높았고 노랑물봉선(0.45 ± 0.08 ugGAE/g)이 가장 낮게 나타났다. 수집지역별로는 각각 DPPH와 ABTS의 경우 노랑물봉선, TPC의 경우 가야물봉선, 노랑물봉선, 물봉선, TFC의 경우 처진물봉선이 지역별 차이를 보였다. 이번 연구 결과를 토대로 국내 자생하는 물봉선속 분류군 별 항산화활성과 생리활성물질 차이를 확인할 수 있었고 추후 유용 소재로써의 이용과 우수 개체선발에 도움이 될 것으로 사료 된다.
