The present study was performed to analysis of aquatic insects community at Tamjin river system from September 1994 to January 1995. The total taxa of aquatic insects was identified 93 species 72 genera 37 families in 9 orders. Among them major groups were Ephemeroptera (22 species) and Coleoptera (20 species). The fauna was dominated by Ephemeroptera (52.8%), Diptera (14.3%), and Trichoptera (12.8%). The seasonal species number of collected specimens was 57 in summer, 54 in autumn and 50 in winter. Mostly dominant species were belonged to Ephemeroptera, above all Uracanthella rufa dominated and its indices ranged from 0.34∼0.99. Diversity indices were 0.13∼3.62. According to the saprobic system based on the diversity indices of aquatic insects, all the sites were determined as β-mesosaprobic or origosaprobic area.

Purpose & Method: Based on a large amount of research concerning the recognition of local residents in an era of an increasing number of multi-cultural families, this study aimed to provide fundamental data for program development and policies. As well, the data was stratified based on understanding of multi-cultural society, recognition of multi-cultural families, and social and economic adaptability of multi-cultural families. Result: The available literature supports the view that an understanding of a multi-cultural society and recognition of multi-cultural families encourages an emphasis on maintaining ethnicity and respect for diverse cultures. Parental approval for friendships with members of multi-cultural families tends to be encouraged, although there is still resistance to marital ties with such families. The literature indicates that immigrant women participate in economic activities of their adopted locale and adapt to the new societal structure. A positive correlation between recognition and interests in social and economic adaptiveness was apparent. Conclusion: Findings of the study suggest that complement, development, and application of realistic programs and institutional policies are required to understand multi-cultural families and establish a multi-cultural society. Ongoing research will be valuable in resolving outstanding questions and clarifying political alternatives.

This study was conducted to evaluate the biological water quality by aquatic insects community analysis in Tamjin river system. The total taxa of aquatic insects was identified in all sites 93 species. 71 genera, 37 families in 9 orders: In summer, 57 species, 43 genera, 24 families, 9 orders, in autumn, 54 species, 41 genera, 25 families in 7 orders, and in winter, 50 species, 41 genera. 26 families in 7 orders were recorded. According to the analysis of biological indices of dominance index(DI), diversity index(H`), pollution index(PI) and biotic index(BI), Water quality of majority in suveyed sites was either oligosaprobic or β-mesosaprobic. It was β-mesosaprobic in all sites except for site 5 in summer. Whereas in autumn, site 5, 6, 7, 10 were oligosaprobic and the rest were β-mesosaprobic. In winter, site 2, 4, 5, 6 and 7 revealed as oligosaprobic, site 10, 11, 12 and 13 as β-mesosaprobic, and site 8 as polysaprobic condition.

The total taxi of aquatic insects in the Tongbok stream were 78 species, 54 genera, 29 families in 8 orders. Among them, major groups were mayflies(24 species) and caddiesflies(17 species). The seasonal species number of collected specimen were similar, that is, they occurred 44 species in winter, 45 species in spring and summer respectively, and 39 species in autumn. In proportion of individuals at this surveyed stream, caddisflies were the highest(42%) and mayflies were 30%. Mostly dominant species were belonged to caddisflies and mayflies. Above all, Hydropsyche KUb and serratella rufa were dominant species. Dominant indices ranged from 0.25∼0.88. Species diversity indices showed 1.14∼4.29.

역률 개선을 위한 부스트 컨버터는 CCM (전류 연속 모드) 동작 시, 주 스위치에서 발생되는 스위칭 손실과 다이오드 역회복 특성에 따른 손실로 인해 저효율 및 회로발열, 신뢰성 저하 등의 문제점이 존재한다. 본 논문에서는 이러한 문제점 해결을 위해 새로운 무손실 스너버(Lossless Snubber)를 제안하고, 제안된 회로의 이론적 분석과 600W급 시작품 제작을 통한 실험적 결과를 제시한다.

The taxa of benthic macroinvertebrates in the upper region of the Cheungam stream was composed of 76 species, 61 genus, 41 families, 13 orders, 4 classes in 3 phyla. Among them, aquatic inserts containing 71 species (93%) were the major group. According to order, Ephemeroptera containing 26 species was abundant, and Trichoptera containing 19 species, Plecoptera 13 species an? Diptera 11 species were the major taxa. The seasonal species number of collected specimens was most numerous in spring (57 species) and similar in other seasons (41∼44 species). On the one-to-one propotion, Ephemeroptera were the highest (52%), and Trichoptera was 19%, Diptera 16%, Plecoptera 9%. DOminant Species were Epeorus, Cincticostella castanea, Serratella rufa and Hydropsyche belonging to Ephemeroptera and Trichoptera. Dominant indices ranged from 0.34∼1.00. Species diversity indices showed 0.00∼3.82. According to saprobic system based on the species diversity indices, water quality was evaluated to be oligosaprobic and β-mesosaprobics. The biological water quality as in biotic and pollution indices was evaluated oligosaprobic in site 1, 2 and 6 and β-mesosaprobics in site 3, 4 and 5.

Background: Epidural opioids and local anesthetics provide excellent postoperative analgesia. In addition, soft tissue and intra-articular injection of bupivacaine and morphine may have a beneficial analgesic effects after total knee arthroplasty (TKA). This study was designed to assess the additional analgesic effect of combined soft tissue, and intra-articular injection of morphine and bupivacaine in patients undergoing TKA under spinal anesthesia with continuous epidural morphine and bupivacaine injection. Methods: Forty patients aged 55 to 75 years for a TKA under spinal anesthesia were randomly divided into 2 groups. The both group of patients received a continuous epidural infusion using a two-day infusor containing morphine 5 mg in 100 ml of 0.125% bupivacaine. The experimental group of patients (n = 20) received soft tissue, and intra-articular injection containing 10 mg morphine in 100 ml bupivacaine 0.125%. The control group of patients (n = 20) received soft tissue, and intra-articular injection of 100 ml normal saline. Postoperative pain was assessed using the visual analog scale (VAS) at 1, 2, 4, 8, 12, 24, and 48 h postoperatively and side effects, such as hypotension, nausea, vomiting, pruritus, and respiratory distress were recorded. Whenever patients demanded supplemental analgesia, diclofenac sodium 75 mg was injected intramuscularly and the need for additional analgesic requirement was recorded. Results: The experimental group of patients had significantly lower pain score and analgesic requirements than the control group for 2 days. There was no difference in the incidence of side effects between groups. Conclusions: Combined soft tissue, and intra-articular injection of morphine and bupivacaine with continuous epidural morphine and bupivacaine infusion reduces postoperative pain and supplementary analgesic requirements than continuous epidural morphine and bupivacaine infusion only in patients undergoing TKA.
