Bentic macroinvertebrate and fish fauna were investigated from September 2008 to October 2009 in the middle reach of the Suyoung river in Busan. During the survey period benthic macroinvertebrates were collected total 35 species at the three sites (Hanmul-gyo, Dongcheon-gyo, Seokdae Jct.) of Suyoung river. At that sites, species diversity index was 1.9, 1.5, 1.6, dominance index was 0.75, 0.81, 0.86 and Korean Saprobic Index (KSI) was 1.8(B), 4.4(D), 4.4(D) on average, respectively. Dominant species was Caenis Kua, Chironomidae sp., at Hanmul-gyo site and Limnodrilus gotoi, Chironomidae sp., at Dongcheon-gyo and Seokdae Jct. sites. Fish fauna was also investigated at the two sites (Hanmul-gyo and Seokdae Jct.) of Suyoung river. Total caught fishes were 10 species 32 individuals in the first survey and 6 species 26 individuals in the second survey. Dominant species was Carassius auratus in the both surveys. Index of Biological Integrity (IBI) value was C grade at the Hanmul-gyo and D grade at the Seokdae Jct.

Background and objective: The prolonged COVID-19 pandemic has had significant impacts on mental health, which has emerged as a major public health issue around the world. This study aimed to analyze trends and network structure of 'grow-your-own (GYO)' through Instagram, one of the most influential social media platforms, to encourage and sustain home gardening activities for promotion of emotional support and physical health. Methods: A total of 6,388 posts including keyword hashtags '#gyo' and '#growyourown' on Instagram from June 13, 2020 to April 13, 2021 were collected. Word embedding was performed using Word2Vec library, and 7 clusters were identified with K-means clustering: GYO, garden and gardening, allotment, kitchen garden, sustainability, urban gardening, etc. Moreover, we conducted social network analysis to determine the centrality of related words and visualized the results using Gephi 0.9.2. Results: The analysis showed that various combinations of words, such as #growourrownfood, #growourrownveggies, and #growwhatyoueat revealed preference and interest of users in GYO, and appeared to encourage their activities on Instagram. In particular, #gardeningtips, #greenfingers, #goodlife, #gardeninglife, #gardensofinstagram were found to express positive emotions and pride as a gardener by sharing their daily gardening lives. Users were participating in urban gardening through #allotment, #raisedbeds, #kitchengarden and we could identify trends toward self-sufficiency and sustainable living. Conclusion: Based on these findings, it is expected that the trend data of GYO, which is a form of urban gardening, can be used as the basic data to establish urban gardening plans considering each characteristic, such as the emotions and identity of participants as well as their dispositions.

This study examines the effects of removal of the sediment protection weir at Taehwa river mouth on hydraulic and around river environment considering the fact that the effects of the sediment protection weir which is installed to protect water level drop of Ulsan harbor caused by sediments according to flood in Taehwa river, Dong-chun, and so forth may add water quality contamination by flow stagnance in normal and drought period and accumulation of pollutants. The result is as follows. First, it is estimated from the examination of variation characteristics water depth and level for Taehwa river before and after removal of the sediment protection weir that about 0.01m of water depth down according to removal of the sediment protection weir occurs when low flow runs between the sediment protection weir which is located about 2.3km away from the estuary and Samho-gyo which is about 9.0km away from the sediment protection weir, and about 0.01~0.56m(directly upstream point of the sediment protection weir 0.56m, Myongchon-gyo 0.14m, Ulsan-gyo 0.03m, and Taehwa-gyo 0.02m) downs when design flood flows between the sediment protection weir and the upstream of Taehwa-gyo which is 10km away from the sediment protection weir. Therefore, it is thought that variation of hydraulic characteristics of water depth down and so on according to removal of the sediment protection weir is slight because water depth variation is only about 1cm between directly upstream point of the sediment protection weir and Samho-gyo. Next, it is estimated from the examination of variation characteristics of flow velocity for Taehwa river before and after removal of the sediment protection weir that about 0.0lm/s of flow velocity increase occurs between the directly upstream point of the sediment protection weir which is about 2.4km away from the estuary and the directly upstream point of Samho-gyo when low flow runs, and about 0.01~0.44m/s increases between the sediment protection weir and Samho-gyo when design flood flows. Therefore, riverbed erosion by the increased flow velocity is concerned but it is thought that the concern about riverbed erosion is not great because the mean velocity is about 0.07~1.36m/s when low flow runs, and about 1.02~2.41m/s when design flood flows for the sector which experiences the flow velocity variation.

The GyoJungEuiSeoGook(校定醫書局, the bureau for revising of medical books) which was established in the 2nd year of InJong GaWoou of Song dynasty, made comparative analyzation about various kinds of publication and reference materials of all classical medical books that was published until Jin Han and Su Dang dynasty, revised the medical books like as Bozushinnongboncho(補注神農本草), Zungkwangbozuhwangjenegyungsomun(重廣補注黃帝內經素問), Shanghanlon(傷寒論), Bigupchunggumyobang (備急千金要方), Magkyung(脈經), Oedaebiyo(外臺備要), Hwangjechimgugapeulgyung(黃帝鍼灸甲乙經), Cchunggumikbang(千金翼方) etc. The signification of such revision was not only to preserve the materials which may be lost before, bibliographically and also make the books of Hwangjenegyung(黃帝內經), Shanghanlon(傷寒論) etc. become more regularly. And it made the foundation of Korean Medical research depends on the documentary records so as to make it have big development by deductive method till the beginning of modern age. The success of GyoJungEuiSeoGook(校定醫書局) indicates that the stagnation of Korean Medical research due to it's behind with the development of politics-economy, social culture and scientific technology which based on western scientific culture. So we may draw the conclusion that the success of scientific research needs to parallel with the external and internal factors of the surrounding science.

동학교는 김주희가 세운 동학계 신종교단이다. 동학교가사에 나타난 사상의 요체는 용어의 빈도수와 읊어진 구절의 내용을 고려하여 '도로 선천(先天)'사상이라고 볼 수 있다. 동학의 시운관(時運觀)이 '다시 개벽(開闢)'사상이라면, 동학교의 시운관은 '도로 선천(先天)'사상이다. 동학교에서는 선천이라는 용어를 특히 강조했고, 역학(易學)을 활용하여 노래했으며, '음양의 마주 봄'으로 개벽의 상황을 읊었다. 동학교에서는 후천의 운수마저 다한 다음에야 비로소 '도로 선천'이 이루어지리라고 강조한다. 이 '도로 선천'의 운수가 회복되면 목덕(木德)으로 상징되는 '봄<춘(春)>'이 다시 돌아올 것이라고 노래한다. 동학교에서는 새로운 운수(運數)의 전개를 '역(易)의 회복'으로 설명한다. 새로운 질서와 규범이 전개될 새 세상을 '도로 선천'으로 부르는데, 이때가 되면 '도덕세계'가 이루어져 도덕 문명이 전개될 것이라고 주장한다. '도로 선천'을 회복하는 운수가 바로 천도(天道)가 회복되는 일과 같다고도 노래한다. '도로 선천'사상의 특성은 첫째, 복고적 체계를 지향한다. 둘째, 과거지향적 사상이다. 셋째, '도로'는 '근원으로 돌아가자.', '근본을 회복하자.'라는 실제의 행동을 유발하고 권유하는 생각이다. 동학교의 '도로 선천'사상은 당대의 여러 신종교와는 다르게 선천(先天)에 대해 독창적인 관념과 인식을 부여했으며, 새로운 해석의 틀을 제시했다. 선천을 폐기해야만 할 낡은 시대로 규정했던 일에서 벗어나 지향해야 할 새 시대로 이해했다. 따라서 동학교의 '도로 선천'사상은 동양 전통의 과거로의 회귀와 복귀를 추구하던 일을 계승한 사상의 하나로 재평가되어야 하겠다. 하지만 '도로 선천'사상에 구체적 방법론이 매우 부족하다는 점은 단점으로 지적될 수 있다. 그리고 동학교의 '도로 선천'사상에는 윤리의식이나 도덕적 덕목이 부족하며, 정작 선천(先天)에 대한 설명이 부족하다. 따라서 동학교의 '도로 선천'사상은 선언적 구호에 그친 감이 있다.
