This study was conducted to investigate the dominance and distribution of weed species in organic and conventional paddy fields. The organic paddy fields were maintained for organic farming for more than five years in Anseong, Gyeonggi province of Korea. According to the Braun-Blanquet method, 42 and 36 weed species were found in the organic paddy fields in 2015 and 2016, respectively, while 38 and 36 weed species were found in the conventional paddy fields in 2015 and 2016, respectively. As a result of two years’ survey, 53 species from 24 families in the organic paddy fields were identified and classified as 32 annuals, 3 biennials and 18 perennials. In conventional paddy fields, 51 species from 24 families (30 annuals, 6 biennials, and 15 perennials) were identified. According to the classification by family, the most abundant weed species were Compositae (9 species), followed by Poaceae (8 species) and Polygonaceae (6 species) in organic paddy fields. In conventional paddy fields, Compositae (9 species) were the most abundant weed species, followed by Cruciferae (6 species), Poaceae, Polygonaceae, and Cyperaceae. This result indicates that the difference in diversity of weeds in paddy fields was influenced more by the agricultural environment than the type of cultivation. Our results could be used as a base data to control the occurrence of weed species in the paddy fields.

Purpose: The purpose of this study is to identify the lifetime sports participation constraint factors of the kidney disabled through surveys against 189 kidney disabled and to propose plans to support lifetime sports by conducting in-depth interviews with experts on kidney-disabled people. Method: The research method of this study was mainly composed of two parts. First, a questionnaire survey was conducted to investigate the participation constraints in sports for all people with kidney disabilities. Second, individual in-depth interviews were conducted with 6 related experts to investigate to support lifetime sports for people with disabilities. Results: There was a major constraint in terms of securing time for lifetime sports as an individual participation constraint. Also, for the environmental participation constraint, people with kidney disabilities indicated that the lack of program variety was the main constraint. Finally, physical limitations due to disability from a kidney transplant were pointed out as the main constraint for lifesports participation. Specifically, regarding the individual participation constraints, the experts suggested designing a customized program and representative sport, and also supporting economic resources considering the characteristics of the kidney disabled. Regarding the environmental participation constraints, the experts suggested setting of support entity as the top priority, planning lifetime sports centered on rehabilitation, providing support for facilities, and strengthening the leader’s competency. Lastly, regarding the physical and psychological participation constraints, the experts suggested publicity support for the kidney disabled to improve the awareness of the non-disabled. Conclusion: In Korea, lifetime sports of people with kidney disability have not yet started, even the first step. The fact that there is no theoretical basis for supporting lifetime sports and there is no survey on the demand for lifetime sports for all transplanted people shows this very well. It is expected that this study will greatly contribute to the development of policies to support lifetime sports for the transplanted disabled in Korea.

This study was conducted to identify problematic weed species in grape orchard fields to establish basic information for suitable weed control. Surveys of weed species occurring in grape orchards were conducted in Chungnam province including Daejeon and Sejong of Korea from April to June and from September to October in 2015. From the surveys, 50 weed species belonging to 23 families (33 annuals and 17 perennials) were identified. In the first survey, the most dominant weed species by the importance values was Poa annua (7.07) followed by Echinochloa crus-galli (6.56), Digitaria ciliaris (6.43) and Capsella bursapastoris (5.63). In the second survey, Rorippa palustris (9.59), Eclipta alba (9.13), Digitaria ciliaris (7.68) and Poa annua (7.68) were dominant. Different weed species and dominance patterns were detected according to weed control methods in the grape orchards. Seven weed species belonging to six families were identified in the field in which herbicides were being used as a weed control method. However, most weed species (21 species belonging to 9 families) were occurred in the mowing + tillage fields. These surveys provide information about seasonal variations of weeds species occurred in grape orchards and impact of different weed control methods on the weed occurrence. 본 연구는 충남지역 포도원의 발생잡초를 확인하고 잡초관리기술개발의 기초자료로 활용하기 위하여 2015년 4월부터 6월, 9월부터 10월까지 2차례에 걸쳐 대전광역시와세종특별자치시를 포함한 충청남도지역의 포도원에서 잡초분포조사를 수행하였다. 충남지역 포도원에서 발생하는잡초는 일년생 33종, 다년생 17종을 포함하는 23과 50종의발생을 확인하였다. 1차 조사에서는 새포아풀(7.07), 돌피(6.56), 바랭이(6.43), 냉이(5.63)가 우점하였고, 2차 조사에서는 속속이풀(9.59), 가는잎한련초(9.13), 바랭이(7.68), 새포아풀(7.68) 순으로 우점하였다. 잡초방제방법에 따른 잡초발생은 제초제만 처리한 경우 6과 7종으로 잡초종의 발생이 가장 적었으며, 예초와 경운을 이용한 경우 9과 21종으로 가장 많은 초종이 발생하는 것으로 나타났다.
