이종태,김은미 한국국제경영관리학회 2022 국제경영리뷰 Vol.26 No.4

With the recent emphasis placed on the Global Value Chain (GVC) in the field of international business, there has been growing attention for sustainable management encompassing not only the economic performance of firms participating in GVC activities but also their environmental and social performance. Presenting international entrepreneurial orientation as a leading factor in sustainable GVC performance, this study aims to investigate the effects of international entrepreneurial orientation on sustainable GVC performance. In addition, the purpose of this study is to examine the moderating effects of social capital, such as structural, relational, and cognitive capital, on the relationship between international entrepreneurial orientation and sustainable GVC performance. To this end, a survey was conducted with Korean manufacturing exporters in Pusan and South Gyeongsang regions, and hypotheses were verified based on the collected final 205 samples. As a result, it was confirmed that all the three sub-factors of international entrepreneurial orientation have positive effects on sustainable GVC performance. Additionally, among the social capital types, structural and cognitive capital showed significant and positive moderating effects on the relationship between international entrepreneurial orientation and sustainable GVC performance. This study have academic implications in expanding the leading factor of GVC performance focused on the network perspective to international entrepreneurial orientation and examining the moderating roles of social capital. This study also provides managerial implicatoins in suggesting that it is necessary for firms participating in GVC to take a strategic approach to achieving sustainable GVC performance through international entrepreneurial orientation and that positive effects of international entrepreneurial orientation on sustainable GVC performance can become greater when further utilizing social capital. 최근 국제경영분야에서 글로벌가치사슬(GVC)의 중요성이 부각되고 있으며, 특히 이러한 GVC 활동의 성과와 관련해 참여 기업들의 경제적 성과 뿐 아니라 환경적 및 사회적성과의 개념을 포괄하는 지속가능경영에 대한 요구가 높아지고 있다. 본 연구는 국제기업가지향성을 지속가능한 GVC성과의 선행요인으로 제시하여 GVC지속가능 성과에 어떠한 영향을 미치는지 실증적으로 규명하고자한다. 나아가 국제기업가지향성과 지속가능한 GVC 성과관계에서 사회적자본(구조적자본, 관계적자본, 인지적자본)의 조절효과를 함께 살펴보는데 연구목적이 있다. 이를 위해 부산・경남 제조기업을 대상으로 설문조사를 하였고, 최종 회수된 205개의 설문지를 바탕으로 연구가설을 검증하였다. 분석결과, 국제기업가지향성이 GVC 지속가능 성과에 유의한 정(+)의 영향을 미치는 것이 확인되었다. 또한 사회적자본 중 구조적자본 및 인지적자본이 국제기업가지향성과 GVC 지속가능 성과관계에 유의한 정(+)의 조절효과가 있음이 확인되었다. 본 연구는 네트워크 관점에 초점이 맞춰진 GVC성과의 선행요인을 국제기업가지향성으로 확장하고, 나아가 사회적자본의 조절효과를 함께 살펴보았다는 점에서 연구의 의의가 있는 것으로 판단된다. 또한 본 연구는 GVC 참여기업에게 최고경영자의 국제기업가지향적 역량 발휘를 통해 지속가능한 GVC 성과달성을 위한 전략적 접근이 필요함을 시사하며, 더불어 사회적자본 활용이 함께 제고될 때 국제기업가지향성이 지속가능한 GVC 성과에 미치는 긍정적인 영향이 더 커질 수 있음을 제시하였다는 점에서 실무적인 시사점이 있는 것으로 기대된다.

이종태,이원환,Lee, Jong Tae,Lee, Won Hwan 대한토목학회 1983 대한토목학회논문집 Vol.3 No.1

장주기파(長週期波)에 의한 항내(港內)의 반응(反應)을 예측(豫測)하기 위하여 비선형(非線型) 편미분방정식(偏微分方程式)으로 표현(表現)되는 2차원(二次元) 부정류(不定流)의 운동방정식(運動方程式)과 연속방정식(連續方程式)을 확정(確定)하고, 이 식(式)들에 Abbott의 Implicit 형(型) 차분형(差分型)을 적용(適用)하여 유한(有限) 차분방정식(差分方程式)의 형태(形態)로 유도(誘導)한 후(後), double sweep 알고리즘에 의하여 해석(解析)하는 수학적(數學的) 모형(模型)을 개발(開發)하였다. 본(本) 모형(模型)은 임의(任意)의 파형(波形), 풍속(風速)과 수심(水深), 위도(緯度) 등(等)을 입력자료(入力資料)로 하여 임의(任意)의 지형(地形)을 가진 항내(港內)에서의 반응(反應)을 해석(解析)할 수 있도록 설계(設計)되었다. 특(特)히 파향(波向), 이송항(移送項), 항입구(港入口)로 되돌아 나오는 에너지의 방사현상(放射現象) 등(等)을 수치해석적(數値解析的)으로 처리(處理)하는 수법(手法)의 개발(開發)에 관(關)하여 연구(硏究)하였다. 본(本) 모형(模型)에 의한 해석결과치(解析結果値)는 1차원(次元) 및 2 차원(次元) 정진동(靜振動)(seiche) 수치실험(數値實驗)을 통(通)하여 검정(檢定)하였으며, Ippen과 Goda의 이론해석치(理論解析値) 및 실험결과치(實驗結果値)와 비교(比較)하였다. A mathematical model for the two-dimensional unsteady flow was developed by introducing Abbott's implicit finite difference operator and double sweep algorithm, which could be applied to simulate the respose of a harbor against the intrusion of long waves through the entrance connected to open sea. In order to improve its accuracy corresponding to the field phenomena, bottom resistance, Coriolis force, wind effect terms were included and wave direction and radiating effect was considered. The result of seiche test was always stable and the amplitude was accurate. Some phase shift was occured, but it could be reduced by using small values of Courant number and many points per a wave length as well. A comparision with the Ippen and Goda's theoritical and hydraulic experimental works was fulfilled.

이종태,윤세의,김정환,Lee, Jong Tae,Yoon, Sei Eui,Kim, Jung Hwan 대한토목학회 1994 대한토목학회논문집 Vol.14 No.5

본 연구는 도시 배수구역에서 지표면유출과 우수로의 홍수추적 과정을 통하여 홍수량을 산정하는데 있어서, 지표면유출 해석방법이 결과치에 미치는 영향을 분석하였다. 지표면유출 해석이론의 비교연구를 위해서는 RUNOFF, ILLUDAS, SBUH, RRL 등의 해석모형들을 사용하였으며, 배수관망내 흐름 해석에는 EXTRAN을 사용하였다. 가상 및 실측 강우, 유출량자료가 있는 유역에 대하여 각각 유출해석을 실시하였다. 각 도시 소배수구역의 유출모형에 의한 결과는 도시홍수량 산정에 상당한 영향을 미치고 있음을 보여주고 있다. 지표면유출 해석 결과치에 가장 큰 영향을 미치는 인자는 도달시간으로 판단되었다. 적용 모형 중 RUN-EX(RUNOFF-EXTRAN) 법이 포장, 비포장유역의 해석에 모두 적합하였으며, 다른 모형들에 비해 실측치에 가장 근사하였다. The effects of the calculation method of surface runoff on the estimation of flood in urban drainage basin were analyzed in this study. In comparing with surface runoff methods. RUNOFF, ILLUDAS, SBUH and RRL were investigated. To route the flow in sewer/conduits EXTRAN was applied. The Kings Creek and Gray Haven drainage basin's measured data of rainfall and runoff were used in comparing the computed results. The results show that the greatest effect factor on surface runoff in urban small area is the concentration time. The results estimated by each model which are composed with EXTRAN show that the scheme for surface runoff gives considerable effect on the flood hydrograph in urban drainage system. RUN-EX method gives the most similar simulation results among the surface runoff models, and is more applicable for paved and unpaved basins than others.

개수로 만곡부에서의 중심각 변화에 따른 흐름특성

이종태,윤세의,Lee, Jong Tae,Yoon, Sei Eui 대한토목학회 1987 대한토목학회논문집 Vol.7 No.3

본 연구는 수심이 작은 만곡수호에서 중심각과 저면마찰의 변화에 따른 흐름특성을 분석하기 위하여 만곡부의 중심각이 $30^{\circ}$, $60^{\circ}$, $90^{\circ}$, $120^{\circ}$, $150^{\circ}$, $180^{\circ}$인 수로모형올 선택하였으며, 저면 마찰이 비교적 클 경우(C=30)와 작은 경우(C=60)로 구분하였다. 만곡수로내의 중심각 변화에 따른 수면형, 유속분포 및 유향 등에 관하여 검토하였다. 만곡수로내의 최대수위 발생지점은 중심각에 관계없이 만곡수로 입구로부터 $15^{\circ}$ 하류단면부근의 외측하단에서 발생된다. 저면마찰조건이 최대유속선의 이동경로에 미치는 영향은 만곡수로의 중심각이 약 $150^{\circ}$ 이상인 경우에서 뚜렷하다. 속도수두에 대한 횡방향 수면차의 비는 만곡수로의 중심각이 증가할수록 커지는 경향을 보여 주었다. 중심각에 관계없이 만곡부 시점에서의 유향은 내측으로 종점에서는 외측으로 편기된다. The flow characteristics in the shallow open channel bends are investigated, whose total angles were 30, 60, 90, 120, 150 and 180 in degree, and whose bed frictions were relatively rough(C=30) and smooth(C=60), respectively. The terms analyzed in this study are the water surface profile, the distribution of velocity and the flow direction, relating to the various total angles in the bends. The maximum depth in the bends could be found at the outside section of the location of $15^{\circ}$ local angle from the bend inlet, having no relation to the total angle and bed friction. It is supposed that the path of maximum velocities is especially influenced by the bottom friction when the total angles are bigger than 150 in degree, approximately. The ratio of the superelevation to the velocity head seems to increase as the total angle of the bends increases. The flow direction is skewed to the inner side at the bend inlet, and skewed to the outside at the bend outlet, regardless of their total angles.

한강의 홍수규모에 따른 인도교수위의 조석영향분석

이종태,한건연,서병하,Lee, Jong-Tae,Han, Geon-Yeon,Seo, Byeong-Ha 한국수자원학회 1993 물과 미래(한국수자원학회지) Vol.26 No.2

한강하구 조위가 인도교 지점의 홍수위에 미치는 영향을 NETWORK 모형에 의하여 분석하였다. '90년의 세 홍수와 2,000~20,000CMS 간 8개의 규모별 가상홍수에 대하여 조석영향성분을 계산하였으며, 홍수량이 커질수록 조석영향은 감소됨을 알 수 있었다. 홍수량이 2,000CMS 이하일 경우에는 조석의 영향으로 약 50Cm 이상의 수위상승을 보여주었으나, 홍수예경보 기준홍수위 4.5m (7,000CMS)에서는 약 9cm에 불과하였으며 이 이상의 홍수규모에서 조석 영향은 무시할 수 있을 정도로 작게 계산되었다. The increased water level caused by tidal motion at Indokyo is analyzed by the NETWORK model. The tidal effect is studied for 3 real floods in 1990 and 8 classified hypothetical floods in which the peak discharges are in the range of 2, 000-20, 000CMS. The result of numerical simulation shows that the tidal effect is decreased as the flood is increased. The surged level is 50cm when the flood discharge is 2, 000CMS, showing that its effect is considerable. However it shows only 9cm when the discharge is 7, 000CMS which corresponds to 4.5cm of standard flood level of MOC. Therefore, so it may be possible to neglect the influence of the tidal fluctuation when the peak discharge of a flood is bigger than 7, 000CMS.

이종태,김진일,Jong-Tae Lee,Jin Il Kim 대한화학회 1984 대한화학회지 Vol.28 No.5

${\alpha},{\beta}$-불포화 알데히드의 아세탈은 브롬화 방향족화합물들과 팔라듐 촉매와 트리에틸아민 존재하에서 쉽게 반응하여 방향족의 conjugated enals을 생성하였다. 불포화 아세탈로서 acrolein diethyl acetal과 methacrolein diethyl acetal을 사용하여 이들을 메틸기와 이소프로필기로 치환된 브롬화 방향족화합물들과 $100^{\circ}C$에서 반응시킨 뒤 생성물들을 옥살산 수용액으로 처리하여 방향족의 conjugated enals를 합성하였다. o-bromotoluene과 methacrolein diethyl acetal과의 반응을 제외하고는 모두 60% 이상의 좋은 수득율을 얻을 수 있었으며 생성물의 구조는 proton NMR과 IR스펙트럼으로 확인하였다. 3-bromopropenal dimethyl acetal 및 (E)-3-bromo-2-methylpropenal diethyl acetal을 할로겐화 비닐화합물의 반응 부위로 하고 1-알켄과 ethyl acrylate등을 올레핀 반응 부위로 하는 반응물들의 역조합(reverse combination)에 의하여 지방족의 2,4-dienals를 50% 이상의 수득율로 합성 할 수 있다. Acetals of ${\alpha},{\beta}$-unsaturated aldehydes reacted readily with aryl bromides in the presence of palladium catalyst and triethylamine to form aryl conjugated enals. Acrolein diethyl acetal and methacrolein diethyl acetal were reacted with phenyl bromides with substituents such as methyl and isopropyl groups at $100^{\circ}C$. The reaction products yields except the reaction of o-bromotoluene with methacrolein diethyl acetal. The products were identified by proton nuclear magnetic resonance and infrared spectroscopy. In the reverse combination of reactants to prepare aliphatic 2,4-dienals in good yield of above 50%, 3-bromopropenal dimethyl acetal and (E)-3-bromo-2-methylpropenal diethyl acetal were used as vinylic halide reactants and 1-alkenes and ethyl acrylate as olefin reactants.

Objectives: The main purpose of this review is to introduce the current status of environmental health indicators of Korea and to share our experience of the developmental process of Korean version of environmental health indicators. Methods: This paper describes 1) the background of environmental health indicators; 2) the ways how we developed environmental health indicators of Korea; 3) the current status of selected indicators; and 4) suggestions for the further policy development. Results: The 6-year long project for the development of environmental health indicator systems in Korea could provide outputs on three major distinct aspects on the indicator issues. Firstly, we have developed the rational process/manual so that the government can select and advocate the potential indicators with a relatively objective manner. Secondly, we have suggested the potential candidate indicators which can be implemented immediately. We also pooled all indicators in order to evaluate the summary index which we expect to tell the status of environmental health. Third, we provided suggestions on the further utilization of this indicator system. Conclusion: The mission of environmental health policy is to resolve the public health problems occurring because of hazardous environment. In order to identify the environmental determinants of the community health problems and to evaluate the effectiveness of the policy implemented, these environmental indicators can be used. Therefore, the government should implement this ready-prepared system of environmental health indicators.
