We analyzed research topics, temporal distribution of field sites, and researcher network of 1,508 limnology publications in the Korean Journal of Limnology (1968~2012) and the Korean Journal of Ecology and Environment (2013~2017). We found that water quality and sediment, phytoplankton, invertebrates, and fish were major subjects during the study periods. Survey of flora and fauna and physiological experiment of freshwater species were the largest subjects during 1970~80s, while other subjects including production, behavior, modeling, and ecological assessment have been rapidly increased since the 1990s. Most of the biological taxa equally studied lotic and lentic system, however, invertebrates and fish related studies more focused on the lotic system. Spatially, the field site of Korean limnology studies was found to be concentrated in main river channels runs through urban areas and artificial lakes than preserved natural areas. Freshwater system, located at the elevation range of 301~400 m (upstream of main channels), had the lowest number of field sites. Collaboration among researchers and different institution types have been steadily increased and expanded as the number of publications increased.

1960년대와 70년대 초기 미국은 인도의 음악, 철학, 종교, 복식 등, 다양한 문화 양식에 관하여 강한 관심을 나타냈고 이는 청년층의 반문화적 행동유형에 의해 시작되어 전반적인 사회계층으로 확산된 문화현상의 한 예로 설명되었다. 이에 본 논문은 Gentlemen's Quarterly 와 Sears and Roebuck Co. Catalgue를 이용하여 수집된 자료를 내용분석법으로 처리하여 미국 남성복에 나타난 인도복식의 영향과 사회계층별 차이점에 관한 실증적인 연구를 시도하였다 연구결과에 따르면 이 시기의 미국 남성복식에 보여진 인도의 영향은 주로 네루 스타일의 복식(Nehru jacket/suit Nehru collar Nehru hat)과 Indian sandal과 jewelry tie-dye와 madras로 의복 직물 악세서리등 다양하게 나타났다 그러나 인도복식으로부터 받은 영향의 내용과 정도는 사회계층에 따라 그 차이가 뚜렷하여 중류층에서는 제한된 종류의 스타일의 단기간 동안 채택되었으나 상류층에서는 다양한 스타일이 비교적 오랜 기간동안 지속되었던 것으로 밝혀졌다 이러한 결과는 중류층의 남성복식이 새롭고 비관습적인 스타일의 채택에 대하여 보수적인 양상으로 띠는 것으로 해석된다. 더불어 인도복식의 영향이 1968년을 절정으로 나타남으로서 이시기의 사회변화가 복식에도 그대로 반영되고 있음으로 보여주고 있다

The mesomyarian and acontiarian actiniaria in Korean waters are identified into 11 species, 11 genera and 8 families. Among them, the following five species are newly recorded to Korean fauna: Isanthus capensis Carlgren; Actinostola carlgreni Wassilieff; Stomphia coccinea (Muller); Parasicyonis actinostoloides (Wassilieff); and Metridium senile (Linnaeus). They are redescribed in detail with figures, and the others are examined and discussed.

The catch and effort information for the yellow croaker from the Yellow Sea and the East China Sea during 1964 through 1971 is analyzed on the basis of the generalized production model. The equilibrium catch curve for m=0.2, the best estimate of the skew parameter, is obtained, and the maximum equilibrium catch is shown to be 37,306M/T. It appears that equilibrium catch curve for the yellow croaker is positively skewed and the fishing beyond the maximum of the yield curve will result in a less pronounced decline in yield than would be predicted by the Schaefer model.

Relative light intensity was observed with underwater illuminometer (Cs Photoelectric cell, glass window) at the mouth of Yeong-il Bay, and relative vertical clearness and extinction coefficient were calculated from the relative light intensity data. Relationship between extinction coefficient and transparency in this region is also shown.

"국가 또는 지자체는 환경전문공사를 다른 업종의 공사와 분리발주하여, 중소환경전문공사업체를 지원해야 합니다. 또 일정 금액 이하의 환경전문공사는 환경산업이 자리 잡을 수 있도록 일정기한 동안 대기업의 참여를 제한해야 합니다." 국회 환경노동위원으로 활동하고 있는 서용교 국회의원은 환경분야에도 대기업과 중소환경업체와의 상생의 길을 모색해야 한다고 강조했다. 서 의원은 이밖에도 폐기물 관련법 개정안 등 다수 입법발의 했다. 서용교 의원은 1968년 경상남도 밀양에서 태어나, 1993년 서울대학교 국사학과를 졸업했으며, 제18대 대통령선거 박근혜후보 중앙선대위 직능총괄본부 환경본부장으로 일 했었다. 제19대 국회의원 선거에서는 새누리당 부산 남구(을) 선거구 국회의원에 출마해 당선 되었다. 현재 서 의원은 국회 환경노동위원회에서 활동 중이다. 다음은 서용교 의원과의 인터뷰 내용이다.

By means of past data, taken from the annual catches of anchovy landings in Korea, from the year 1926 to 1967, as reported in the Annual Statistical deports of Fisheries, the future annual catches from the year 1968 to 1973 were predicted by statistical extrapolation. The trend C(t) in the 42 year period above was interpreted by the least square method. Also, the ratio of the actual annual catches Ct to this trend C(t) was regarded as a stationary variate and the serial correlation coefficients $r_k$ were calculated. The type of statistical variate model was therefore determined by the correlogram. A periodical analysis, using Whittaker's method, was performed and a harmonic analysis was also performed. According to these calculations the stationary variate at was fixed and the annual catches following the year 1967 were predicted by extrapolation.

Some marine sponges were collected from Jindo Island, Kuryongpo and Chejudo Island during the period from 1986 to 1999. Among the identified species, two species Myxichera spinuloso (Tanita, 1968) and Clathria (Clathria) acanthostyli (Hoshino, 1981) are new to the Korean fauna.

The secular fluctuations of catches and fishing grounds of mackerals and the oceanographic conditions for the fishing grounds are examined by using the data of catches of mackerals by middle and large class purse-seiner during 1951 to 1981 and those of oceanographic observation carried out by Japan Meteorological Agency. The results are as follows; The fishing grounds of mackerals are respectively distributed at northeastern and southwestern areas from the central part of the East China Sea through every season of the studied years: 1968, 1974 and 1980. The narrow belt type of fishing grounds were formed inside of the Kuroshio in spring and winter of the three years. In summer mackeral species move northward and the fishing grounds are formed in the southern sea of Korea. In winter, however, mackeral species move southward and the fishing grounds are appeared in the Tsushima Current region. The dispersion of fishing grounds is generally larger in summer and smaller in spring, and especially it is the largest in summer in 1980. It seems that the concentration and dispersion of fishing grounds are related to the depth of thermocline and the position of horizontal temperature gradient in this area.

Noise and air pollution, which accompany the development of industry and the increase of population, contribute to the deterioration of urban environment. The air pollution level of Seoul has gradually increased and the city residents are suffering from a high pollution of noise. If no measures were taken against pollution, the amount of emission of pollutant into air would be 36.7 thousand tons per year per square kilometer in 1975, three times more than that of 1970, and it would be the same level as that of United States in 1968. The main sources of air pollution in Seoul are the exhaust has from vehicles and the combustion of bunker-C oil for heating purpose. Thus, it is urgent that an exhaust gas cleaner should be instaled to every car and the fuel substituted by less sulfur-contained-oil to prevent the pollution. Transportation noise (vehicular noise and train noise) is the main component of urban noise problem. The average noise level in downtown area is about 75㏈ with maximum of 85㏈ and the vehicular homing was checked 100㏈ up and down. Therefore, the reduction of the number of bus-stop the strict regulation of homing in downtown area and a better maintenance of car should be an effective measures against noise pollution in urban areas. Within the distance of 200 metres from railroad, the train noise exceeds the limit specified by the pollution control law in Korea. Especially, the level of noise and steam-whistle of train as measured by the ISO evaluation can adversely affect the community activities of residents. To prevent environmental destruction, many developed countries have taken more positive action against worsening pollution and such an action is now urgently required in this country.
