The research was carried out to investigate the contamination of stream water by the acid mine drainage originated from the abandoned coal mines and coal waste rock in Keumsan, Chungnam. The pH, sulfate and chemical compositions in the stream water were analyzed. At the polluted sites, the pH of stream water was the strong acid, ranging from 3.46 to 4.29. The pH shows negative correlations with sulfate, manganese, copper, zinc, iron and magnesium concentrations. Sulfate concentrations of the polluted stream water, 236.73 - 310.53㎎/ℓ, had 10 times more than those of the non-polluted stream water. The concentrations of heavy metals, Mn and Fe, in the polluted water were 0.56 - 0.83㎎/ℓ and 5.89 - 10.58㎎/ℓ, respectively. The Mn concentrations were 20 times higher than those of the non-polluted stream water. Compared with those in the non-polluted stream water, the Mg and Ca concentrations in the polluted stream water were high because of leaching from rock and soil to water by the acidifications. Calculated AMDI(Acid Mine Drainage Index) values are low in the polluted stream water, relative to those of the non-polluted water.

In this study, a multivariate time series analysis was conducted to identify various variables that impact ocean freight rates in addition to supply and demand factors. First, we used the ClarkSea Index, Clarksons Average Bulker Earnings, and Clarksons Average Tanker Earnings provided by the Shipping Intelligence as substitute variables for the dependent variable, ocean freight. The following ndependent variables were selected: World Seaborne Trade, World Fleet, Brent Crude Oil Price, World GDP Growth Rate, Industrial Production (IP OECD) Growth Rate, Interest Rate (US$ LIBOR 6 Months), and Inflation (CP I OECD) through previous studies. The time series data comprise annual data (1992-2020), and a regression analysis was conducted. Results of the regression analysis show that the World Seaborne Trade and Brent Crude Oil P rice impacted the ClarkSea Index. Only the World Seaborne Dry Bulk Trade impacted the Clarksons Average Bulker Earnings, World Seaborne Oil Trade, Brent Crude Oil Price, IP, and CP I on the Clarksons Average Tanker Earnings.

이 연구는 청소년의 자율 협력적 독서실행 모형을 제시하고 협력적 독서방식이 청소년의 독서유효성에 미치는 효과를 검증하였다. 이를 위하여 전국 8개 지역, 61개 중 고등학교에 68개 독서클럽을 조성하고 연구집단을 독서미흡집단, 독서양호집단, 독서혼합집단으로 구분하여 청소년의 자율 협력적 독서실행을 4개월 동안 실시하였다. 독서유효성의 설문지를 제작하여 사전과 사후검사를 실시하고 SPSS 통계 프로그램을 통해 분석하였다. 연구 결과, 청소년들의 독서유효성은 긍정적으로 향상되었으며 독서미흡집단이 가장 효과적인 것으로 나타났다. 또한, 청소년의 독서행동에도 긍정적인 변화가 나타났으며 독서유효성의 변화는 독서행동에 영향을 미치는 것으로 파악되었다. This study was to present a model of cooperative reading practice and verify reading effectiveness on youth. For this purpose, 68 reading clubs were established in 61 districts and 8 high schools. The research groups were classified as the poor reading group, the good reading group, and the mixed-skill reading group. The cooperative reading groups were carried out for four months. We developed a questionnaire on Reading effectiveness conducted it pre- and post-test, and analyzed the results through the SPSS statistical program. We found that there was a positive change in the reading effectiveness of youth and overall-the highest effectiveness was found in the poor reading group. In addition, there was a positive change in the reading behavior of youth. The change of reading effectiveness was found to affect reading behavior.

The invertase (EC 3.2.1.26), which catalyzes the hydrolysis of sucrose, has been purified 71-fold from Jerusalem artichoke tuber. Electrophoresis showed that the native enzyme is consisted of single polypeptide chain of 86,000 daltons. Optimum pH and temperature for the enzyme action were pH 7.0 and 40℃, respectively. The enzyme exhibited high hydrolytic activity to sucrose, but no activity on inulin. The enzyme had an apparent Km of 24.7 mM for sucrose.

Objectives : To estimate mumps incidence during the study period and to evaluate the completeness of case reporting. Methods : Capture-recapture methods, originally developed for counting wildlife animals, were used. The data sources were 1) the National Notifiable Communicable Disease Reporting System (NNCDRS; 848 cases), 2) the School Health Reporting System, temporarily administered by the Division of Education (SHRS; 1,026 cases), and 3) a survey of students (785 cases). We estimated the number of unobserved mumps cases by matching the three data sources and fitting loglinear models to the data. We then determined the estimated total number of mumps cases by adding this to the number of observed cases. Completeness was defined as the proportion of observed cases from each source to the total of estimated cases. Results : The total number of observed cases was 1,844 and the total number of estimated cases was 1,935 (95%, CI: $1,878\sim2,070$). The overall completeness was 43.8% of the NNCDRS, 53.0% of the SHRS, and 40.6% of the survey. However, completeness varied by area and age. Conclusion : Although the completeness of NNCDRS data appeared higher than in the past, it is difficult to generalize this result In Korea, it is possible to estimate the size of health hazards relatively cheaply and quickly, by applying capture-recapture methods to various data using a multiple data collection system.

Bis(silyl)alkylbenzenes such as bis(1-sila-sec-butyl)benzene (1) and 2-phenyl-1,3-disilapropane (2) were synthesized in high yields by the reduction of the corresponding chlorosilanes with $LiAlH_4$ in diethyl ether. The dehydrocoupling of 1 and 2 was performed using group IV metallocene complexes generated in situ from $Cp_2MCl_2$/Red-Al and $Cp_2MCl_2$/n-BuLi (M = Ti, Hf), producing two phases of polymers. The TGA residue yields of the insoluble polymers were in the range of 64-74%. The molecular weights of the soluble polymers produced ranged from 700 to 5000 ($M_w$ vs polystyrene using GPC) and from 500 to 900 ($M_w$ vs polystyrene using GPC). The dehydropolymerization of 1 and 2 seemed to initially produce a low-molecular-weight polymer, which then underwent an extensive cross-linking reaction of backbone Si-H bonds, leading to an insoluble network polymer.

This study was performed to investigate the present contamination level of total mercury in freshwater fishes. The samples were collected at kangkyung area located in Kum river from May to July in 1890. Experimental subjects were fifty seven case from seven kinds of fishes, and dissected into four parts; muscle, bone, liver and gill. Contents of total mercury in the parts were determined by mercury analyzer. The results were as follows: 1. In the muscle tissue, mean Contents of total mercury was 0.351ppm; the highest was 0.522±0.038ppm in shake head; the lowest was 0.207±0.022ppm in eel. 2. The order of the mean value of total mercury contents in four parts were muscle>liver>bone>gill, respectively. 3. Food chain was a factor which affected the concentration of total mercury in the fishes. In the most case, carnivorous fish had higher level of total mercury than omnivorous. 4. In the relationship between size and mercury concentration, mercury level tended to increase with size, age.

국소적인 진행성 위암의 근치적인 치료는 수술이 첫 번째 방법이다. 하지만 위암을 진단받은 환자 중에서 약 30% 만이 수술이 가능한 진행성 위암으로 진단을 받으며 그 중 약 40-60% 만이 R0 절제술이 가능하다. 저자들은 위 주위 림프절과 복강 림프절, 장막을 침범한 진행성 위암을 진단받은 환자를 3주간의 수술 전 항암화학요법으로 치료하였고, 근치적인 목적으로 위 절제술을 시행하였다. 조직병리검사에서 완전히 괴사된 종양 조직을 관찰할 수 있었고, 수술 후 현재까지 3차례의 추가적인 전신 항암화학요법을 시행하고 있으며, 추적 복부 전산화단층촬영에서 재발을 시사하는 소견을 보이지 않았다.
