The information about the physicochemical environments, the species distribution and community of the epilithic diatom cells in Pyengchang river and inflow streams of Gangwon-do were studied for assessment of biological water quality from June 2008 to October 2010. Total 112 diatom taxa were identified with 2 orders, 9 families, 26 genera, 95 species and 17 varieties. Among the total taxa identified, 13 taxa, 52 taxa and 15 taxa represented the family Achnanthaceae, Naviculaceae and Bacillariaceae, respectively. The pH values of the water was found to be neutral to alkaline due to the limestone grounds of Pyengchang river and inflow streams. The 13 taxa including Epithemia adnata, belonged to alkaline-water diatoms, and three species - Cymbella japonica, Eunotia major and Fragilaria capitellata - are known to be acidic-water species. The species, Hannaea arcus, known as a cryophilic and mountain periphyton was identified at IF2, IF3 and IF4 in low water temperature environments at high altitudes, being a dominating species in P1 and IF1. Four saproxenous species - Achnanthes convergens, Cocconeis placentula var. lineata, Cymbella turgidula and Hannaea arcus - were dominant at some sampling sites. For biological water quality assessment, IF2, IF3 and P3 showed low water quality class. The values of DAIpo and TDI were 10.6 ~ 98.0 and 13.8 ~ 94.2, respectively. Therefore, biological water quality in Pyengchang river and inflow streams was relatively desirable.

In the present study, the community distribution, functional feeding groups, and habitat groups of the benthic macroinvertebrates from Gayasan National Park were investigated at eight different sites from 2015 to 2016. The correlation between habitat altitude and each group type was analyzed statistically. Biodiversity indices, including dominance, diversity, richness, and evenness indices, were calculated. The results showed a total of 4,216 individual benthic macroinvertebrates were collected, including 4 phyla, 6 classes, 16 orders, 40 families, and 100 species. Gammarus sobaegensis was dominant with 0.141% dominance, and the subdominant species was Epeorus nipponicus with 0.088% dominance. The EPT group(Ephemeroptera, Plecoptera and Tricoptera) accounted for 71.00% of the total species and 67.69% of the total individuals. The number of scraper species was highest, and the number of gathering collector individuals was highest among functional feeding groups. The individual number of scrapers(r=-0.358, p < 0.05) and gathering collectors(r=-0.343, p < 0.05) decreased with increasing altitude. The numbers of species and individuals of clingers and sprawlers were highest among the habitat groups. The individual number of clingers(r=-0.547, p < 0.01) and burrowers(r=-0.331, p < 0.05) significantly decreased with increasing altitude. The diversity and richness indices were higher in St. 3 than in the other sites. The dominance index was highest in St. 2, and the evenness index was highest in St. 7. We evaluated the biological water quality with several known methods, and concluded that ESB(Ecological score of benthic macrovertebrates community) and GPI(Group polution index) were more suitable than KSI(Korean saprobic index) and BMI (Benthic macrovertebrate index) to assess the biological water quality of Gayasan mountain stream water.

Backgrounds: In order to prevent dental injuries that often occur in child and adolescent, it is intended to investigate and assess actual state of the injury development, present epidemiological background, and consider and discuss for preparing preventive means against the injury development. Purpose: It was attempted to understand major features of dental injuries developing in child and adolescent and indentify high risk factors of dental injuries in child and adolescent. Methods: In this study, 523 cases of computerized data collected as disease entities of dental injuries among 1-18 years old patient visiting S university hospital located in Seoul in 2009 were analyzed and following results were obtained. Results: It was found that the ratio of dental injuries by genders in child and adolescent was 66.14% of male and 33.86% of female. It was shown also that causes of dental injuries by ages were more in order of falling, bumping, chewing, traffic accident, sports, violence, and crash. In addition places where dental injuries occur by ages were home in less than 5 year old group, park, playground, and play yard in 6-11 year old group, park, playground, and play yard also in 12-14 year old group, and stairs, road, and outdoor places such as mountain climbing, beach, and camping in 15-18 year old group. It was found that time rages when dental injuries in child and adolescent often develop were 15-19 o'clock for falling, 15-19 o'clock for crash, 15-19 o'clock for bumping, 19-03 o'clock for violence, 15-19 o'clock for traffic accident, 15-19 o'clock for sports activity, and 15-19 o'clock for chewing. Conclusion: Background of dental injury inducing factors are very complicated and diversified, so deep study and analysis are required for its prediction. Therefore, it seems necessary to identify risk factors by phases such as before, at, and after accident, establish strategies to reduce injury development, and develop and utilize necessary programs.

This study was carried out to investigate the degree of contamination in private-drinking water supply (PDWS) and simple-piped water supply (SPWS), and to compare of water quality between them for 3 years from 1990 to 1992. The results of the study were as follows: 1. Private-drinking water supply (PDWS) (1) Field-Site (ㄱ) The items which were very significantly over the criteria (p<0.01), were temp., pH, NO-N, standard plate count (S.P.C.) and Coliform. (ㄴ) No. of households which were over the criteria, were 11.2~51.7% in temp., pH, NH$_3$-N and NO$_2$-N, and 83.1~93.3% in NO-N, S.P.C. and Coliform. (2) Moutain-Site (ㄱ) The items which were over the criteria, were NO$_2$-N (p<0.05), S.P.C. (p<0.01) and Coliform (p<0.01). (ㄴ) No. of households which were over the criteria, were 33.6 ~ 75.6% in NO$_2$-N, S.P.C. and Coliform. (3) No. of households which were fit to the criteria of all items, were 9.0% in field-site and 14.1% in mountain-site. 2. Simple-piped water supply (SPWS) (1) The items which were very significantly over the critera (p<0.01), were standard plate count (S.P.C.) and Coliform. (2) The water qualities of adjacent and remote samples were better than those of source samples. (3) Residual chloride was not detected in any sample. In conclusion, rural community requires to be continually performed the policy of safety drinking water supply, and to be devised an epoch-making counterplan for the level-up of simple-piped water supply (SPWS), espically on the method of disinfection.

The present study was accomplished from October, 1992 to June, 1993 in order to examine the seasonal community structure of aquatic insects and the biological estimation of water quality by the aquatic insects of the Jungneung and Gokneung streams in the Mt. Bukhan. The obtained results are as follows: 1. The total taxa of aquatic insects appeared as 77 species, 45 genera, 28 families in 7 orders. 2. Seasonal occurrence species numbers showed the highest in the autumn of the Jungneung stream (19 species) and in the spring of the Gokneung stream (41 species). Seasonal occurrence individual numbers showed the highest in the summer of the Jungneung and Gokneung streams (5,901, 3,180 individuals) and the lowest in the autumn of Jungneung stream (612 individuals) and in the winter of the Gokneung stream (1,764 individuals). 3. Annual dominance indices showed 0.52 (stJ1)~1.00 (st.J3) range in the Jungneung stream, and 0.47 (st. G1)~0.76 (G2) range in the Gokneung stream. 4.

본 연구는 월악산국립공원의 서식지에 따른 어류상 현황 및 어류군집의 특성을 분석하기 위하여 수행되었다. 월악산국립공원의 주요 하천에서 공간균등계층추출법으로 총 20개의 지점을 선정하였으며, 계절별로 3회 조사를 실시하였다. 서식지의 물리적 환경은 대부분 산간계류형(Aa) 하천이었으며, 하상구조는 큰돌과 자갈이 산재되어 있는 형태였다. 서식지의 평균고도는 304.4m, 평균 수심은 40.3cm로 대부분 1m를 넘지 않았으며, 하천 차수는 3~5차하천까지 분포하였다. 서식지별 물리적 환경요인에 대하여 주성분 분석을 실시한 결과 고도에 따라 하상물질 특성이 달라지는 것으로 나타났다. 조사 결과 출현한 어종은 총 7과 16종 2,183개체가 확인되었으며, 우점종은 참갈겨니(86.2%), 아우점종은 버들치(3.8%)였다. 법정보호종으로는 멸종위기 야생생물 II급 가는돌고기가 본 조사에서 처음 출현하였다. 어류군집의 순위풍부도 곡선의 모형을 분석한 결과 20개 지점중 9개 지점에서 Zipf 모형이 도출되었으며, 대수정규 모형 3개 지점, 선점 모형 4개 지점, 그밖에 4개 지점은 1종만이 출현하여 분석이 불가능하였다. 환경요인에 따른 어류군집의 특성을 파악하기 위해 20개 지점과 출현종을 대상으로 정준상관분석을 실시한 결과 고도에 따른 서식환경의 차이로 인하여 어류군집이 나뉘는 것으로 파악되었다.
