水源汚染에 따른 高度 淨化處理 시스템 開發에 관한 硏究 : 洛東江 水源을 중심으로 with regard to water resourse of Nakdong river

姜龍太,玄吉秀,金泳珍 동아대학교 환경문제연구소 1991 硏究報告 Vol.14 No.1

The experimental results of pilot-scale plant of water treatment using the water resource of Nakdong river are summarized as follows. 1. At flow rate of 100-120 m/day, Biofilm filtration process as pretreatment process showed that the removal rates of NH₄-N and ABS ranged from 90 to 100 percent and from 50 to 70 percent, respectively. 2. For flocculation process, alum dosage in reducing turbidity were more effective to be decided by K value obtained from GCT than by Jar-test. 3. Dual-layer filter, in case of filtration time, was longer of 2 times as 50 hours tan that of single-layer filter, as well as to produce good quality of treated water compared to the single-layer filter.

이 연구는 시민참여와 정부신뢰와의 관계를 분석하는데 그 목적이 있다. 이를 위하여, 이 연구에서는 시민참여를 전통적인 오프라인 시민참여와 디지털 방식인 온라인 시민참여로 그 유형을 분류하고, 오프라인 시민참여와 온라인 시민참여의 경험이 정부신뢰와 어떤 관계가 있는지를 분석하였다. 2차 자료를 활용하여 빈도분석, 교차분석, t-test, 분산분석, 회귀분석 등을 실시한 결과 먼저, 우리나라 시민참여 경험자는 약 22% 정도이며, 오프라인 시민참여 경험자는 약 12%, 온라인 시민참여 경험자는 약 15%, 그리고 온라인과 오프라인 시민참여를 모두 경험한 시민은 약 5% 정도인 것으로 나타났다. 또한, 시민참여와 정부신뢰와는 관계를 분석한 결과 통계적으로 유의미한 관계가 없는 것으로 나타났다. 오히려, t-test 및 분산분석 결과 오프라인 및 온라인 시민참여 경험자에 비하여 무경험자의 정부신뢰 수준이 상대적으로 약간 더 높은 것으로 나타났다. 시민참여의 경험 유무 만으로 정부신뢰를 설명하는데는 한계가 있음을 보여 주는 결과일 뿐만 아니라 시민참여를 제도적으로 보장하는 것에서 나아가서 시민참여가 실질적 효과를 높일 수 있도록 시민참여과정에서 정부와 시민의 보다 적극적인 노력이 필요함을 보여주는 결과라 하겠다. Trust in government adds legitimacy to political system, provides social stability, and helps government to work effectively. In addition it increases cooperation between governments and citizens, and improves effectiveness of government affairs. However, citizens' trust in government has been quite low sine 1990s. In Korea, citizens' trust in government dropped after financial crisis in late 1990s. Various literatures indicated that citizen participation is one of the best ways to increase citizens' trust in governments. Especially as information technology increases, it is expected that citizens acquire information about different policy areas, and actively participate in surveys, discussion, and policy evaluation through internet. This research attempts to prove the relationship between citizen participation and trust in government by comparing online and offline citizen participation. The research utilized 2nd dataset from 'the influence of information on citizens' participation in policy-making.' With various statistical techniques such as frequency analysis, cross tabulation, ANOVA, and regression analysis, the characteristics of offline and online policy participants are examined. The results showed that citizens, who participate in policy-making processes more actively both online and offline, trust in government less. Comparing online and offline participation, online participants distrusted government more than offline participants. Such variables as policy competitiveness, democracy in government, quality of government, and transparency in government have direct influences on trust in government. However, citizen participation is not statistically significant. Key Words:Citizen Participation, Traditional Citizen Pariticipation, Digital Citizen Participation, Trust in Government.

우리나라 여성의 삶의 질에 관한 연구

강한솔,정수현,황은진,이정주,노승용 서울여자대학교 여성연구소 2011 여성연구논총 Vol.26 No.-

People are getting more interested in their “quality of life” as they achieved certain level of economic development. Governments pay great attention on well-being and happiness of people as well and try to find the best way to improve citizens' quality of life. However, South Korea is still on 27th out of 39 OECD and G20 countries in quality of life index, which means that there are great needs to improve Koreans' quality of life. Moreover, it is expected that Korean women's quality of life might be worse than this in its patriarchal environments. In fact, there are few research regarding Korean women's quality of life and it is unknown what personal and social factors affect Korean women's quality of life and how we can improve it. This research attempts to find out factors related to Korean women's quality of life through the surveys of 536 Korean women. The results show that quality of life is most influenced by factors such as self-fulfillment, socio-economic independence, satisfaction with the residence, and satisfaction with cultural activities. In addition, happiness of Korean womem is greatly affected by various factors such as mental health, interpersonal relationship, self-respect, self-fulfillment, socio-economic independence, satisfaction with the residence, and satisfaction with cultural activities. Among various factors related to quality of life and happiness of Korean women, scores of self-respect, self-fulfillment, and interpersonal relationship are high, while scores regarding income are relatively low.

오스테나이트계 TP347 스테인레스강의 파괴저항특성 평가

강병구,김수용,석창성 成均館大學校 科學技術硏究所 1999 論文集 Vol.50 No.1

The objective of this paper is to evaluate the material properties of TP347 stainless steel and their associated welds and the welded joint of the carbon steel and the stainless steel manufactured for primary coolant system of Ulchin 3 & 4 nuclear power plants. The effect of various parameters such as pipe size, welding method, chemical composition, crack plane orientation, metallography and fractography on the material properties were discussed. Test results showed that the effect of pipe size on fracture toughness was negligible while the effect of welding method on fracture toughness was significant. In addition, the drop of fracture toughness in the field fabrication weld of TP347 stainless steel is probably due to the large amount of σ-phase precipitated on the δ-ferrite boundary and the large size dimple.

Polyamide capsules containing aqueous solution of GOD were prepared by the interfacial polymerization of ethylenediamine and terephthaloyl chloride, and were coated with the bilayer membrane of dialkyldimethyl- ammonium bromide(2C_nN^+2C_1, n=11, 12, 13, 15). The activity control of the immobilized GOD through the capsule membrane was investigated for the effects of temperature and pH changes.

흰쥐 뇌에서 전기경련 충격에 의한 CREB 인산화의 발달단계에 따른 변화

강웅구,정희연,안용민,정선주,전송희,박주배,조수철,김용식 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.3

연구목적 : 이 논문에서는 뇌에서 전기경련 충격(Electroconvulsive shock. ECS)에 의한 전사인자 CREB의 인산화를 발달단계에 따라 알아봄으로써 정신장애의 신경발달학적 이해를 위한 생물학적 기반지식을 얻고자 하였다. 방 법 : 생후 7. 14. 21일 및 성년 흰쥐에 ECS를 가하고 시간별로 해마 및 소뇌 조직을 얻어 CREB의 인산화를 알아보기 위해 특이 항체로 면역블롯을 실시하였다. 결 과 : 발달단계에 따라 해마에서는 CREB이 감소한 반면 소뇌에서는 CREB이 증가하였다. 기저상태의 CREB 인산화는 해마와 소뇌에서 생후 7일에 비해 14일 이후 증가하였는데, 소뇌의 경우 CREB의 양증가와 비례하였다. ECS 후 CREB인산화 증가는 해마에서는 생후 21일 이후에 나타났으나, 소뇌에서는 생후 7일은 물론 성년에서도 나타나지 않았다. 결 론 : CREB 매개 신호전달은 발달단계별 및 조직별 활성의 차이를 나타내었으며 해마에서는 생후 21일 이후 ECS에 의해 활성화되었지만, 소뇌에서는 그렇지 않았다. 해마에서 ECS에 의한 CREB 인산화 증가는 c-fos 유전자의 발현과 관계있으리라고 생각되지만, CREB의 Ser-133 인산화 만으로는 발달단계 및 조직에 따른 c-fos 발현의 특이성을 설명할 수 없었다. Objectives : In order to understand the biological basis of neurodevelopmental perspectives of mental disorders, the authors investigated the developmental and regional changes in the phosphorylation of the transcription factor CREB following the electroconvulsive shock(ECS) in rat brain. Methods : Rats of various age groups(7, 14, 21 days postnatal and adults) were given ECS and their hippocampi and cerebella were dissected at specified time points. The content of CREB and phosphorylated CREB were measured by immunoblot analysis. Results : The amount of CREB increased in the hippocampus and decreased in the cerebellum according to the age. Baseline levels of CREB phosphorylation in both tissues were increased from postnatal 14 days, and it was proportional to the amount of CREB protein in the cerebellum. In the hippocampus, ECS increased the phosphorylation of CREB at postnatal 21 days, but in the cerebellum, ECS did not increased the phosphorylation of CREB in any age group. Conclusion : CREB mediated signal transduction pathways showed developmental and tissue-specific changes. ECS increased the phosphorylation of CREB in the hippocampus by postnatal 21 days, but not in the cerebellum. CREB activation is supposed to be related with the induction of c-fos after ECS in the hippocampus. However, the Ser-133 phosphorylation of CREB could not completely explain the developmental and tissue specificity of c-fos induction.
