안승섭,최윤영,이수식 한국환경과학회 2002 한국환경과학회지 Vol.11 No.4

In this study, water protection reservoir is selected as the target which is located at the estuary of Taehwa river to analyze and examine the effects of hydraulic structure on river environment. This study examined the water quality variation characteristics among many effects of hydraulic structure on river environment before and after removal of the sediment protection reservoir when low flow is yielded. This study aims at the definition of factors which cause the change of ecological environmental friendly river space development through the comparison of stream variation conditions(depth, velocity, and etc.) and riverbed variation characteristics with ecological depth condition of Taehwa-river's channel for each representative species of fish and examination those. Firstly, form the examination result of water quality when low flow is yielded before and after removal of the sediment protection reservoir for problems about water quality of river due to flow amount decrease in river, it is found that DO decreases about 0.78~0.86ppm at the lower stream of Myeongchon-gyo, and BOD decreases about 0.06~0.24ppm from right upper stream to the direction of estuary when the sediment protection reservoir is removed. It is known from the above that there is some improvement of water quality from the lower stream of Taehwa-gyo to the estuary in case of removal the sediment protection reservoir. Nextly, it is thought that the effects on ecosystem due to water depth and draw down in channel is not serious on the basis of the examination of water quality analysis result according to removal of sediment protection reservoir and hydraulic depths for reservation of ecosystem, these are 10~40㎝ for breeding season, 10~50㎝ for fry period, and 10~100㎝ for adult period of the representative species of fish in Korea.

In this study, water protection reservoir is selected as the target which is located at the estuary of Teahwa river to analyze and examine the effects of hydraulic structure on river environment. This study aims at the definition of factors which cause the change of ecological environment of river due to the effects of the sediment protection reservoir, and the proposal of the direction of environmental friendly river space development through the analysis and examination of stream variation conditions and riverbed variation characteristics among many effects of hydraulic structure on river environment before and after removal of the sediment protection reservoir when design flow is yielded. Firstly, in case of removal the existing sediment protection reservoir, the hydraulic variation characteristics like depth drop due to removal of the sediment protection reservoir are thought of little because it is examined that depths drop with about 0.01m and 0.01~0.56m when low flow is yielded and design flood yielded, respectively. Nextly, as the examination result of the variation characteristics of flow velocity in case of removal the existing sediment protection reservoir, it is thought that the concern about riverbed erosion is not serious according to the analyzed result as the mean velocity of the channel section where the velocity varies in case of removal the sediment protection reservoir is about 0.07~1.36m/s when low flow is yielded, and is about 1.02~2.41m/s when design flood is yielded despite riverbed erosion is concerned as it is examined that flow velocity is getting increase as about 0.01m/s when low flow is yielded and about 0.01~0.44m/s when design flood is yielded. Lastly, from the prediction result of riverbed variation for each flow amount condition before and after removal the sediment protection reservoir, it is known that the variation range of riverbed is nearly constant when flow amount of the channel exceeds a specific limit as it is analyzed that the more flow amount, the more erosion and sediment in the channel section of down stream part of the sediment protection reservoir and the sediment protection reservoir-Samho-gyo, and the variation ranges according to flow amount between flood condition and design flood condition have little difference in the channel section of the upstream of Samho-gyo.

정보통신기술의 발달과 국제기업활동 변화에 미치는 영향에 관한 연구

황윤섭 한국인터넷비즈니스학회 2002 인터넷비지니스연구 Vol.3 No.2

정보통신기술의 급속한 발전은 모든 기업들의 활동에 영향을 미치고 있으며, 특히 다국적기업들의 활동과 관련하여 많은 학자들은 지리적 시대의 종말(end of geography) 이라는 표현과 함께 국제기업활동의 모든 면에서 근본적이고도 혁신적인 변화가 일어날 것으로 예상하였다. 하지만, 2000년 후반 dot.com 기업들의 몰락은 정보통신산업의 발전과 기업활동의 변화에 대해 냉정한 현실인식이 필요하다는 점을 일깨워 주었다. 본 연구는 정보통신기술의 발전이 다국적기업의 활동과 관련된 이론들이 어떤 변화를 겪게 되었으며, 앞으로의 변화과정은 어떠할 것인가를 예측함으로써 막연한 기대감과 추측만으로 정보통신산업의 발전을 바라보는 시각에서 벗어나 변화의 요소를 파악하고 이에 대한 대비를 할 수 있도록 하는데 연구의 목적이 있다 정보통신기술의 발달은 정보 교류를 활성화시키기 때문에 외국예서 활동함으로 인한 불리함이 줄어들고, 지리적 거리감을 상당히 줄일 수 있으며, 제품 및 기술의 수명주기를 짧게 할 것이다. 또한, 내부적 정보 네트워크를 발전시킴으로써 무형자산의 가치를 높이도록 할 것으로 전망된다. 시장의 실패로 인하여 내부화가 진행된다는 내부화 이론에 대해서는 정보통신기술의 발달에 따라 정보에 대한 접근이 쉽고, 비용이 줄어들기 때문에 시장의 실패가 일어날 여지를 줄 인다는 견해가 지배적이다. 따라서 기업들은 내부화 보다는 아웃소싱을 통한 시장거래를 활용하게 것이다. 생산입지의 문제에 있어서는 요소부존과 비용의 차이로 인한 입지우위는 점차 축소될 것이고, 특히 디지털화 될 수 있는 무형재의 경우 많은 영향을 받게 될 것이다. 따라서, 입지는 사회간접시설이 잘 갖추어져 있고 지적재산권에 대한 보호가 잘되어 있는 곳으로 이동할 것이라는 견해가 지배적이다. 이와 같은 변화의 방향을 기반으로 다국적 기업들의 활동변화를 예측할 수 있으며, 이미 세계 무대에서 활동하고 있는 우리나라 기업들도 어떻게 변화해야 하며, 세계 시장의 경쟁에서 경쟁우위를 점하기 위해서는 어떤 내부적 능력을 갖추어야 하는지를 파악할 수 있었다. There has been considerable speculation, in both the business and academic press, regarding how the information and communication technology (ICT) shrinks distance, eliminates intermediaries, and brings about closer integration of the world economy. A corollary of this is the implication that the conduct of global business will be changed in fundamental ways. ICT advances were forecast to transform world business by linking suppliers, firms and customers in a seamless web that would cover the entire world. But the crash of the dot.coms in the second half of 2000 and the dramatic drop in the value of high-technology company shares that followed have sobered the mood and brought considerable realism to the market and to these predictions. In spite of this phenomenon, ICT advances will actually affect to the transformation of business processes, especially in the field of international business. The field of international business has made considerable progress in the development its own theoretical framework. Now we have to consider how ICT advances affect to the transformation of MNCs" business process. In this study I examined which factors can be affected from ICT advances and the potential direction of MNCs" business processes. For this purpose, 1 described foreign direct investment (FDI) theory and its major factors, then selected factors that are sensitive to ICT-driven transformation. This study may provide the perception of the ICT influence on international business processes and its direction.

목적 : 본 연구는 소아, 청소년의 강박 증상을 평가하기 위한 도구인 아동용 예일-브라운 강박척도(Childen's Yale-Brown Obsessive Compulsive Scale : Y-BOCS)의 한국판을 제작하여 그 신뢰도와 타당도를 검증하고자 시행되었다. 방법 : 강박장애로 진단된 42명의 아동과 청소년들을 대상으로 CY-BOCS를 시행하였다. 평가자간 신뢰도를 측정하기 위하여 20명의 환자를 2명의 평가자가 동시에 면담하였다. 수렴타당도와 변별타당도의 검증을 위해 총괄적인 임상 인상척도-강박장애(Clinical Global Impression-Obsessive Com-pulsive Disorder : CGI-OCD). 아동용 Leyton 강박 척도(Lryton Obsessional Inventory-Child Version : LOI-CV), 소아우울척도(Child Depression Inventory : CDI), 소아 상태-특성 불안척도(State-Trait Anxiety Inventory for Children : STAI-C)를 시행한다. 결과 : Cronbach's α값으로 평가한 내적 일치도는 0.86으로 높게 나타났다. CY-BOCS 전체 점수 강박사고, 강박행동 소척도 점수에 대한 군내 내적일치도는 각각 0.94. 0.94. 0.84로 우수한 평가자간 일치도를 보였다. CY-BOCS 전체 점수와 CGI-OCD 점수간의 상관관계는 매우 높게 나타났고(r-0.88), LOI-CY 총점과도 통계적으로 유의한 상관관계(r=0.51)가 관찰되었다. CY-BOCS 전체 점수와 STA-I-C의 상태불안 점수간에는 상관관계가 나타나지 않았고(r=0.25), 특성불안 점수(r=0.43) 및 CDI 점수(r=0.49)와는 유의한 상관관계를 나타냈다. 결론 : 본 연구결과, 한국판 CY-BOCS의 높은 타당도 및 신뢰도가 입증되었으며, 향후 강박 증상의 객관적인 평가 및 정량화를 위해 유용하게 사용될 수 있을 것이다. Objective : This study was carried out to evaluate the reliability and validity of the Korean form of the Children's Yale-Brown Obsessive Compulsive Scale(CY-BOCS). Method : Forty-two children with obsessive-compulsive disorder(OCD)(31 boys and 11 girls, aged 7 to 18 years) were assessed with CY-BOCS. Interrater agreement was assessed by two raters in subsample(n=20). discriminant and convergent validity were assessed by comparing CY-BOCS scores to Clinical Global Impression-OCD(CGI-OCD), Leyton Obsessional Inven-tory-Child Version(LOI-CV), State-Trait Anxiety Inventory for Children(STAI-C), and Child Depression Inventory( CDI ). Results : Internal consistency was high, measuring 0.86 for the 10 items and total score. The intraclass correlations for the CY-BOCS total, obsession, and compulsion scores were 0.94, 0.94, 0.84, suggesting excellent interrater agreement for subscale and total scores. The CY-BOCS total score showed highest correlation with CGI-OCD(r=0.88), and significant correlation with LOI-CV(r=0.51), Trait Anxiety score(r=0.43), and CDI scores(r=0.49), but it was not correlated with State-Anxiety score(r=0.25). Conclusion : The results of this study indicate that the Korean form of CY-BOCS is a reliable and valid scale for rating obsessive-compulsive symptom severity. KEY WORDS : Development · Rating scale · Obsessive-compulsive disorder · Reliability Validity.

진입장벽 요인이 향후 투자에 미치는 영향에 관한 연구 : 러시아 제조업 부문에 대한 투자를 중심으로

정헌주,황윤섭,,김희종 서울대학교 러시아연구소 2006 러시아연구 Vol.16 No.1

Any market has its own entry barriers to foreign firms. In this reason, foreign firms. who are entering to a foreign market, must have internal competence which can contribute to overcome the entry barriers and have the capability for adjusting to external environment of foreign market. In this paper we analyzed the rate of entry barriers of external environment of Russian market when Korean firms entering into Russia. In this paper we segmented the external environment that affects to foreign firms as entry barriers such as competitive, socio-cultural, and political-legal environment and analyzed the rate of barriers induced from these environmental factors to foreign firms. The applied method is correlation and multiple regression analysis. The result of empirical analysis is a follows: The competitive environment of local(Russian) market dose not affect to Korean firms as an entry barrier. The local socio-cultural environment, however, significantly affect to foreign firms as entry barrier and negatively affect to sequential entry to sequential entry of Korean firms, and among sub-factors hierarchical behavior of governmental workers, in particular, raises unstability and uncertainty of external environment and negatively affects to Korean firms' investment in the future.
