  • Purpose: This study was conducted to identify the effects of an integrated health improvement program for the elderly based on primary health care posts during the COVID-19 pandemic. Methods: A single group pretest-posttest design (n=16) was employed to evaluate an integrated health improvement program that took place twice a week for 11 weeks. The program was conducted in a small group of no more than 10 people in compliance with the guidelines to prevent COVID-19 infection. The program consisted of various contents such as making letters using blocks, health education, and talking about one's memories. The data were analyzed using the Wilcoxon signed rank test. Results: Following the program, social support (Z=-3.50, p<.001) and quality of life of the elderly (Z=-3.74, p<.001) were significantly improved among depression, social support and quality of life. Conclusion: The integrated health improvement program based on primary health care posts, considered in this study, was useful to improve the social support and quality of life of the elderly in the community, and needs to be applied to a larger number of elderly people throughout the community.

  • Biomonitoring of an invasive alien crayfish species, Procambarus clarkii (Girard, 1852), was performed from February to October 2021, along with environmental DNA analysis, at five locations including Wanju-gun, Hampyeong-gun, Naju-si, Gurye-gun, and Cheongju-si. For the investigation, an umbrella-shaped trap for adults and a hand net for young crayfish were used, and 8 to 10L of freshwater was collected for eDNA analysis. The current status and past distributional records of crayfish in Korea were analyzed along with benthic macroinvertebrates at each survey site. As a result of the investigation, a total of 122 individuals were identified, and Hampyeong-gun recorded the largest number of populations with 59 individuals (48.36%) and the highest environmental DNA (eDNA). The frequency of appearance of P. clarkii was highest in May. The ratio of females to males was 21:5, and the body size was 72.2±21.1mm for female, 80.5±15.6mm for male, and 25.3±9.8mm for young crayfish. P. clarkii introduced into Korea is mainly spreading in the southwest region and it has not been observed in Seoul where there had been a record of appearance in the past. No external symbiosis (Branchiobdellida) of P. clarkii has been identified, and P. clarkii that has appeared in Korea was presumed to be imported from Japan. There are more than eight kinds of exotic crayfish distributed in Korea, and among them, the marbled crayfish (P. virginalis) was identified as a harmful species to the ecosystem of Korea by the Ministry of Environment in 2021. The identified species of benthic macroinvertebrates inhabiting the survey area where P. clarkii has appeared were 69 belonging to 39 families, 15 orders, five classes, and three phyla. Among them, Odonata were the most abundant (16 spp.; 24.62%), followed by Coleoptera (11 spp.; 16.92%) and Hemiptera (11 spp.; 16.92%). In the survey area, one Korean endemic species (Rhoenanthus coreanus), one species (Helophorus auriculatus) classified as Near Threatened (NT) on the Korean Red List, and six species of Crustaceans appeared. In the functional feeding group, the predators appeared predominantly while in habitat oriented group, the climbers appeared to be abundant. It was confirmed that P. clarkii in the survey area prefers an area rich in aquatic vegetation with waterside vegetation, and has high resistance to turbid water quality. The omnivore invader P. clarkii is expected to maintain a competitive relationship with carnivorous benthic macroinvertebrates that are predominant in the same species, and is expected to continue to generate ecosystem disturbance along the food chains.

  • This study was carried out to provide data on current sod production in South Korea. Fifteen items were surveyed including production acreage, species and cultivars, experience on farming, production cost and the others during April to October in 2006. To estimate production acreage, 73 turfgrass growers were interviewed. Estimated acreage for turfgrass production was 2,947 ha. Acreages by province were 1,417 ha in Jeollanam-do(48%), 442 ha in Jeollabuk-do(14.9%), 344 ha in Gyeonggi-do(11.6%), 248 ha in Gyeongsangnam-do(8.4%), and 240 ha in Chungcheongnam-do(8.1%), respectively. The major sod producing regions were Jangseong-gun, Hampyeong-gun, Yeonggwang-gun, Gochang-gun, Sacheon city, Iksan city, Yeoju city, Yeoncheon-gun. Percentage of turf growers over 50 years old was 72.4 percent, which means production was carried out mainly by old farmers. Grower's career over 10 years was 84.8%. Cultivated species and varieties were 'Junggi'(55.5%) of fine-textured Korean lawngrass, common Korean lawngrass(37.4%), Kentucky bluegrass(3.8%), and new zoysiagrass cultivars(0.1%), respectively. Sod size were variable. Sod size of $18{\times}18cm $ was 43.5 percent. Sales route was mainly through sod distributor(40.5%). Sod producing cost was $2,160{\sim}2,730$ won per square meter at Jeolla-do areas.

  • This experiment was carried out in order to study the effect of seasonal changes and location differences on the productivity of the native reed (Phragmites Communis Trinius). The samples of reed were taken at about 30-days interval from May to October, 1982, on the open field of the reclaimed land, the river bank and the tideland in Chonnam area, and measured the yield, the feed compositions and in vitro dry-matter digestibility(IVD). The results are summarized as follow: 1. Plant height was rapidly heightened in May and June, and the number of leaves rapidly increased from May to August. However, dry matter yield increased until September and gradually decreased thereafter. 2. In general, the content of crude protein and the in vitro dry matter digestibility decreased with ageing, and the content of fiber increased. 3. Considerable difference by location in the chemical composition including $SiO_2$, Ca and P was observed. 4. There was a significant negative correlation (p<0.05) between the content of crude protein and that of crude fiber. There was a significant positive correlation(p<0.05) between the in vitro dry-matter digestibility(IVD) by two-stage method and the content of crude protein, and also was a significant negative correlation(p<0.05) between the content of fiber and that of crude protein.

  • This study was carried out to investigate the distribution status and UI(urbanization index) of the naturalized plants and exotic plants. For this purpose 7 cities and counties in the northern South Jeolla Province were selected and investigations were conducted on a total of 14 sites, two sites from each city or county, during the period of March to November 2006. The exotic plants were identified as 111 taxa; 26 families, 79 genera, 105 species, and 6 varieties. As for urbanization index, Hampyeong County had the highest level of urbanization(21.95%) and Gokseong County the lowest level of urbanization(16.38%). Naturalized plants classified as family were as follows: Compositae was 36 kinds(32.43%) Graminae 17 kinds(15.31%) and Leguminosae 7 kinds(6.31%). Major communities of naturalized plants consisted of 21 communities including Robinia pseudoacacia-Amorpha fruticosa community, Erigeron annuus community, Erigeron canadensis community etc. Invasive naturalized plants consisted of 7 taxa: Paspalum disticum var. indutum, Paspalum distichum, Rumex acetocella, Solanum carolinense, Aster pilosus, Ambrosia artemisiifolia var. elatior and Ambrosia trifida. The study shows that the integrated management of exotic plants on a national scale is needed. It also recommend that a systematic and integrated management of exotic plants in the northern South Jeolla Province is crucial to preserve and protect natural species.

  • 현장 계측을 통한 오염부하량 산정은 많은 시간, 노력, 비용을 필요로 한다. 이러한 어려움을 해결하기 위해 오염부하 추정에 관한 많은 방법론들이 제시되고 있으며 개발되고 있는 중이다. 논오염부하 추정을 위한 일환으로 강우사상평균농도(Event Mean Conentration, EMC)에 관한 연구가 많이 진행되고 있다. 하지만, 오염부하량 산정을 위해서는 농도이외의 주요 매개변수인 유출량 산정 또한 중요하다. 하지만 논의 경우 실제 유출량 자료는 흔치 않다. 우리나라의 경우 영농활동이 시기별, 지역별로 비슷한 형태를 가지고 있으므로 이러한 점을 이용하면 유출율을 추정하는데 용이할 것으로 판단된다. 따라서 본 연구는 2004년부터 2007년 영농기 강우-유출량 실측 자료를 이용하여 시기별 유출특성을 파악하고, 논의 시기별 유출율을 제안하였다. 논의 시기별 유출율을 산정하기 위한 시험지구는 영산강 수계내에 위치한 전라남도 함평군 엄다면 화양리 13.69 ha 논지구이며, 2004년부터 2007년 영농기(5월$\sim$9월)동안 모니터링을 실시하였다. 논 배수로 말단에 수위계를 설치하여 수위-유량관계식을 이용하여 유량을 구하였고, 직선분리법을 이용하여 직접유출과 기저유출을 분리한후 강우량과 유출량의 비를 통하여 월별 평균 유출율을 산정하였다. 5월, 6월, 7월, 8월, 9월에 내린 평균 강수량은 각각 40.2, 50.1, 75.4, 75.8, 136.8 mm로 나타났고, 영농기 월별 평균 직접유출량은 각각 9.1, 26.6, 34.6, 42.9, 79.6 mm로 나타났다. 강우량과 유출량의 비를 통해 4개년 5월, 6월 7월 8월 9월 평균 유출율은 각각 0.18, 0.42, 0.40, 0.44, 0.49로 나타나 논의 경우 시기별로 유출율이 차이가 있는 것으로 조사되었다.

  • 한정된 수자원의 이용 및 관리로 매년 물 부족과 물 배분 의사결정 문제가 발생하고 있다. 50년간(1965~2014년) 수자원의 총량은 약 1.2배 증가한 반면 인구수 약 1.8배, 생·공·농업용수의 수요는 약 5배가 증가(국회입법조사처, 2018) 했을 뿐 아니라, 기후변화의 영향으로 인한 강수량의 변화와 지역별 편차가 커져 지속가능한 물관리 필요성이 증대되고 있다. 따라서 효율적인 물관리를 위해서는 관리부처가 분절되어 있는 물순환 계통의 데이터를 통합하는 것이 우선시되어야 하고 이를 통해 물순환 모니터링/평가/예측 기술을 개발할 수 있다. 본 연구에서는 생활용수 물순환 계통 통합 DB를 정의 및 구축하였다. 도시의 관점에서 물순환 시스템을 순차적으로 물 유입(수원~취수장)/전달(정수장~급수지역)/유출(하(폐)수처리장~방류구)의 개념으로 설정하고 DB정의서를 마련하였다. 연구대상지는 가뭄이 장기화가 되고 있는 전라남도중 물순환 계통이 비교적 단순한 네트워크로 형성되어 있는 함평군 도시지역으로 선정하였다. 연구 기간은 총 5년(2017년 1월 1일~2021년 12월 31일)이고 일 단위 실계측자료 위주의 원자료를 구축하였다. 이를 이상치 탐지, 제거, 대체의 과정을 거쳐 품질 보정하고 정제된 시계열 자료에 대한 특성 분석을 하였다. 그 결과, 물순환 계통 내 주요 지점 간의 상관관계 및 지연시간을 통한 물흐름의 시계열적 특성을 파악할 수 있었으며 모형의 적합도를 판단하는 데 활용되는 통계량과 유의미하지 않은 잔차의 자기상관성을 볼 때 물 유입-전달-유출의 단기 예측을 위한 ARIMA(Auto-regressive Integrated Moving Average) 모형의 구축도 가능할 것으로 판단되었다. 다만 여름철 발생하는 방류량의 첨두값을 설명하기 위해서는 강우에 의한 불명수 발생으로 증가하는 방류량을 묘사할 수있어야 하므로 향후에는 물순환계통 외 해당 지역의 불명수(강우 효과)도 하수 방류량의 주요 입력 요인으로 추가 검토할 필요가 있다.

  • The water availability in a river is related to the return flow of residential water. However it is still difficult to determine the exact return flow. In this study, the residential water-cycle system is defined as a process consisting of water inflow, water transfer and water outflow. The study area is Hampyeong-gun, Jeollanam-do, and is set as a single inflow to a single outflow through the water-cycle system after classification of complete and incomplete measurement points. The time-series prediction models(ARIMA model and TFM) are established with daily inflow and outflow data for 6 years. Inflow and outflow are predicted by dividing into training and test periods. As a result, both models show the feasibility of short-term prediction by deriving stable residuals and securing statistical significance, implementing the preliminary form of the water-cycle system. As a further study, it is suggested to predict the actual return flow of the target basin and efficient water operation by adding input factors and selecting the optimal model.
