  • 증발산은 유출량과 같은 다른 수문순환 요소들에 비해 가장 만족스럽지 못하게 설명되는 부분이다. 왜냐하면 증발산은 직접 측정 할 수 있는 것이 아니라 물 수지 등과 같은 간접적인 방법을 통해 추정되기 때문이다. 대부분의 증발산량 산정 모형들은 너무나 많은 종류의 기상자료를 입력자료로 요구하기 때문에 현실적으로 수문학적 모형에 적용되기는 어려운 실정이다. 이에 대해 본 연구에서는 준분포 수문모형인 SLURP 모형을 이용하여 토지피복변화에 따른 증발산량의 변화를 분석하였다. SLURP 모형은 유역 내에서의 증발산량을 산정하기 위해 기상요소뿐만 아니라 토양습윤량의 변화를 고려할 수 있으며 토지피복변화를 반영할 수 있다. 대상유역으로는 우리나라의 5대강 유역을 대상으로 하였으며, SLURP 모형에 탑재되어 있는 Morton CRAE (Complementary Relationship Areal Evapotranpiration) 모형을 이용하여 토지피복별 증발산량을 산정하였다. 5대강유역을 대상으로 토지피복변화분석 및 그에 따른 증발산량 변화를 모의하여 증발 및 증산량의 변화를 확인하였다.

  • Ninety nine random complementary DNA clones from rainbow trout (Oncorhynchus mykiss) liver cDNA library were partially sequenced as one approach to analyze the transcribed sequences of its genome. Of the sequence generated, $64.0\%$ of the ESTs were represented by 29 known genes. Thirty six clones of the unknown gene products potentially represent 31 unique genes. Serum albumin $(16.1\%)$ was the most abundant in the liver. The structural genes in the liver $(19\%)$ were the highly expressed functional category. This research is helpful to understand tissue specific gene expression profile and basic relationship between tissue and functional categories of the genes.

  • The aim of this study is to understand the meaning of Form drawing in which Louis 1. Kahn's principal thought is immanent through the detail analysis on design process of the Phillips Exeter Academy Library, based on his sketches and writings. The basic form is composed of three different space: one where students come together in the presence of books, another for the storage of books, and a third for reading in the light. Through the design process in the Exeter library, the basic form is maintained and it is derived from the consideration of the human activities in the library Particularly, the basic form is shaped around the idea that learning necessarily Involved two complementary activities: on the one hand, the quiet introspective act of reading, and the other, the interpersonal exchange of ideas. And the basic form plays an important role in controlling the relationship between program requirements and formal transformations in the design.

  • The structures built carelessly become the origin of a serious environmental problem caused from the urbanization. To solve this problem, I have considered the characteristics of Atrium as an environment-friendly factor to the office environment. The result is that Atrium protects the insiders health and contributes to the energy saving as it enables the use of natural lights and solar heat first. Second, it gives the office environment liveliness, makes a clean environment and helps the insiders health for introduction of green field. Third, it plays a role of a place for rest, a place for meeting, and a small park by attracting people to the organic space where the inside and outside are connected with a huge glass. On the basis of these characteristics, we should try to prepare the complementary relationship between human beings and nature mutually through its active introduction in the space.

  • Korea and Japan have maintained an intimate relationship of economic exchange. However, even though both countries have made sound advances in the ASIAN market, they have not established mutually remarkable cooperative relations and advances in the ASIAN market. If korean companies with abundant experience and management ability provide able managers and skilled labor and if Japanese companies provide construction technology, capital and information, they could enjoy enomorous mutual benefits by advancing in the area of plant construction in foreign countries. Therefore, if they cooperate with each other by establishing complementary cooperation, both countries can gain an advantage in international competitiveness with western advanced countries.

  • The purpose of this study is to estimate monthly evapotranspiration (ET) using normalized difference vegetation index (NDVI) obtained from NOAA/AVHRR data sets. Actual evapotranspiration was evaluated by the complementary relationship (Morton, 1978, Brutsaert and Stricker, 1979), and monthly NDVI was obtained by maximum value composite method from daily NDVI images in the Korean peninsula for the year 2001. The monthly actual ETs for each land cover were compared with the monthly NDVIs to determine relationships between actual ET and NDVI for each land cover category. There was a high correlation between monthly NDVI and monthly averaged actual ET. This study presents an alternative approach for land surface evapotranspiration based on remote sensing techniques.

  • This paper proposes an Extended and Adaptive Inverse Perspective Mapping (EA-IPM) model that can obtain an accurate bird's-eye view (BEV) from the forward-looking monocular camera on the sidewalk with various curves. While Inverse Perspective Mapping (IPM) is a good way to obtain ground information, conventional methods assume a fixed relationship between the camera and the ground. Due to the nature of the driving environment of the mobile robot, there are more walking environments with frequent motion changes than flat roads, which have a fatal effect on IPM results. Therefore, we have developed an extended IPM process to be applicable in IPM on sidewalks by adding a formula for complementary Y-derive processes and roll motions to the existing adaptive IPM model that is robust to pitch motions. To convince the performance of the proposed method, we evaluated our results on both synthetic and real road and sidewalk datasets.

  • As a revision negotiation on the KORUS FTA has become a national pending issue, this study aims to analyze changes in the trade structure of Korean export industry before and after the KORUS FTA. For the analysis, this study used Market Comparative Advantage(MCA) and Intra-industry Trade(IIT) indexes. Results of the analysis are as follows: First, in analyzing the competitive and complementary relationships of export products using the MCA index, it was discovered that Korea has formed an export-oriented complementary relationship with the United States. Second, the results of analysing IIT showed that Korea has made a low-quality vertical IIT with the U.S. in some items while it has usually made a weak IIT with the U.S.. Based on the results above, this study proposes a few policy suggestions in the following areas: Improvement of competitiveness in trade-deficit service sector, achievement of the balance of profit and loss in goods and service sectors through the revision negotiation of the KORUS FTA, enhancement of competitiveness in competitive and comparative disadvantage items, reinforcement of ability to respond to consumption patterns in U.S. market, etc. in export-dominant items, and pursuit of horizontal-vertical division of labor in comparative advantage items and horizontal division of labor in comparative disadvantage items.

  • Under the continuing economic growth without increase in employment, issues regarding the impact of IT investment on demand for labor have been continuously raised. Under the circumstance, this study carried out an empirical analysis on the impact of IT investment on employment with a sample of 498 businesses whose domestic sales for the period of six years from 2003 to 2008 are KRW 100 billion or above. The result of the analysis found that IT investment increases employment in most of the industries except for some of the service sectors. In the manufacturing industry, more IT investment increased employment but decreased the flexibility in demand for labor; therefore, IT investment has a substitutional relationship with low-skilled labor and a complementary relationship with high-skilled labor. In the areas of electricity, gas and construction, employment increased as IT investment increased, with the greatest flexibility in demand for labor. In the service industry, increase in IT investment led to more employment and higher flexibility in producer services only. On the other hand, there was no meaningful relationship found between IT investment and employment in the areas of distribution services and social services.

  • This study investigates research trends on the Convergence of Chinese and Western Medicine (中西醫匯通, CCWM), by first defining the concepts and the scope of this emerging field, identifying different types of convergence, and suggesting methods to evaluate the process. The author investigates the relationship of CCWM to the Self-Strengthening Movement and the doctrine of Zhongtixiyong (中體西用). Lessons that Korean Medicine (KM) can learn from this approachto help establish relationship between Korean and Western Medicine, are investigated. Proponents of CCWM suggest different types of convergence such as Zhongzhongcanxi (衷中參西), Zhongxizhezhong (中西折衷), and ZhongyiKexuehua (中醫科學化), to accommodate the change in the power dynamics between Chinese and Western medicines. The rigid dual medical system in Korea significantly hinders the potential for convergence. The current system is based on the relativistic model in which the scope of practice for the KM doctor and the Western Medicine doctor are mutually exclusive. Philosophically, the convergence of East-West medicine can be supported by pluralism and monism, while relativism sees it as impossible. A conservative pluralistic model might consider Bogu (補救) of Eastern Medicine, while a more progressive pluralistic model might build a New Medicine which combines the knowledge and techniques of Eastern and Western medicines. An example of monistic model is CAM (Complementary and Alternative Medicine), which aims to scientifically verify the efficacy and safety of the Eastern therapeutic practices and integrate them into Western medicine. This article proposes that as communication and fusion between medical disciplines are essential virtues of contemporary scholarly development, a change that enables the convergence of East-West medicine is needed.
