The geotechnical engineering research group in Korea Institute of Construction Technology(KICT), which was first started as a small sub-division of the civil research group in KICT, became an independent research cluster with nearly 90 researchers including 25 doctors(Ph.Ds). Our geotechnical engineering research group has developed to be the best research center related to geotechnical engineering in Korea in terms of number of budget of projects performed annually. As a reaction to the rapid changes of domestic and international issues regarding geotechnical practices, our group established long-term plans which will lead national research projects. For the successful and efficient research and technology development, the group is subdivided by several specialty-divisions. The divisions under the geotechnical engineering research group are tunnels and underground structures, slopes and embankments, geo-environment, foundations, soil reinforcements, and constructions in extremely cold regions. Our research scopes includes planning, site investigation, design, construction, maintenance and management. The geotechnical engineering research group is continuously and successfully examining and analyzing the most recent trends of technology and is predicting and focusing on the researches of newly-developing fields; therefore, the group has been a leading research group in geotechnical engineering nationally.

Controlling the production of diverse cell/tissue types is essential for the development of multicellular organisms such as animals and plants. The Arabidopsis thaliana root, which contains distinct cells/tissues along longitudinal and radial axes, has served as an elegant model to investigate how genetic programs and environmental signals interact to produce different cell/tissue types. In the root, a series of asymmetric cell divisions (ACDs) give rise to three ground tissue layers at maturity (endodermis, middle cortex, and cortex). Because the middle cortex is formed by a periclinal (parallel to the axis) ACD of the endodermis around 7 to 14 days post-germination, middle cortex formation is used as a parameter to assess maturation of the root ground tissue. Molecular, genetic, and physiological studies have revealed that the control of the timing and extent of middle cortex formation during root maturation relies on the interaction of plant hormones and transcription factors. In particular, abscisic acid and gibberellin act synergistically to regulate the timing and extent of middle cortex formation, unlike their typical antagonism. The SHORT-ROOT, SCARECROW, SCARECROW-LIKE 3, and DELLA transcription factors, all of which belong to the plant-specific GRAS family, play key roles in the regulation of middle cortex formation. Recently, two additional transcription factors, SEUSS and GA- AND ABA-RESPONSIVE ZINC FINGER, have also been characterized during ground tissue maturation. In this review, we provide a detailed account of the regulatory networks that control the timing and extent of middle cortex formation during post-embryonic root development.

This study was attempted to provide a scientific basis for the problem of location selection by spatial scale for efficient promotion of projects related to green care farm complex. Location potential assessment system in local government scale consists of two major components from demand-side and supply-side consideration. The demand-side aspect considered the characteristics of potential users, while supply-side aspect used total 18 indices over 8 divisions under 3 fields. For the location potential assessment in district scale, total 8 indices under 3 major divisions were considered based on biological, physical, social, and economic environment. The application results of the location potential evaluation system in local government scale(excluding metropolitan cities) showed high location potential in southern Gyeonggi Province and near Busan Metropolitan City. As a result of applying the district-scale location potential evaluation system to Geumsan-gun, Geumsan-eup, Chubu-myeon, and Jewon-myeon have high potential. Further studies to improve the applicability of the developed indices are recommended by enhancing assessment indices, complementing base data, and reinforcing with spatial analysis.

주암댐에 유입된 호저퇴적물의 입도(2mm-200{\mu}m,\;200-100{\mu}m,\;100-50{\mu}m,\;50-20{\mu}m,\;<20{\mu}m)별 중금속(As, Cd, Cr, Cu, Ni, Pb, Zn)의 이동과 퇴적 후 중금속의 수직적 분산 특성을 규명하기 위하여 12개 지점의 호저퇴적물과 3개 지점의 코아시료를 채취하였으며, 코아시료는 2-5 cm 간격으로 절단하여 깊이별 간극수와 퇴적물의 중금속 함량을 측정하였다. 호저퇴적물의 퇴적속도를 측정하기 위하여 코아시료에 대한 $^{210}Pb$ 동위원소 연구를 수행하였다. 주암댐 호저 퇴적물의 중금속 및 미량원소의 함량은 퇴적위치와 상관없이 거의 일정한 함량을 보이며.,평균 함량은 $As\;14.9\;{\mu}g/g,\;Cd\;0.81\;{\mu}g/g,\;Cu\;30.7\;\;{\mu}g/g,\;Ni\;34.7\;{\mu}g/g,\;Pb\;63.3\;{\mu}g/g,\;Zn\;87.9\;{\mu}g/g$이다. Cu, Pb, Zn, Ni 및 Cd의 함량은 $20\;{\mu}m$ 이하 입도의 퇴적물에서 가장 높은 반면, As는 $2mm-200{\mu}m$ 혹은 $200-100\;{\mu}m$ 입도의 퇴적물에서 가장 높다. 간극수에 용해된 원소 중에서 가장 함량이 높은 것은 Fe와 Mn 이었으며, 코아시료의 상부로부터 심부로 갈수록 함량이 증가하는 수직적 분산특성을 나타낸다. 반면에 용존 Zn과 Cu함량은 코아시료의 최상부에서 가장 높게 나타나며, 이는 산화:환원 전위차에 따른 유기물질 및 산화광물의 용해작용과 관련이 있다. 코아시료의 퇴적물 내 Cu, Ni, Pb 및 Zn 함량은 0-4 cm구간에서 가장 높은 표면집적 현상이 관찰되며, Pb와 Cu 함량이 현저하게 높은 데, 이는 인위적인 오염에 기인하는 것으로 해석된다. $'unsupponed\;^{210}Pb'$을 이용하여 계산된 호저퇴적물의 퇴적 속도는 $\omega=0.91\;cm\;year^{-1}$ 이며, 이를 적용하면 주암댐이 완공된 이후 약 10 cm의 퇴적물이 평균적으로 퇴적된 것으로 추정된다. 이러한 자료는 주암댐 호수 바닥에 퇴적된 퇴적물의 관리방안을 마련하는 데 중요한 정보로 사용될 수 있을 것이다.

In recent years, the Korean Medical Association has undertaken the feat of establishing the Korean Standard Terminology of Medical Procedures with the dedicated help of 32 medical academic societies. However, because the project is being conducted by several different circles, it has yet to see a clear system of classification. This thesis, therefore, proposes the three principles of scientific properties, usefulness and ideology as the basis for classification system and has developed the Classification System of Medical Procedures in Korea upon their foundation. The methodology and organization of this thesis as follows. First, by adopting scientific classification system of Feinstein(1988), an analysis of the classification systems of the medical procedures in the United States, Japan, Taiwan, WHO was carried out to reveal the framework and the basic principles in each system. Second, the direction of classification system has been constructed by applying the normative principle of medical field in order to show the future direction of the medical field and realize its ideology. Third, a finalized framework for the classification system will be presented as based on the direction of classification system. Of the three basis principles mentioned above, the analysis on the principles of usefulness was left out of this thesis due to the difficulty of establishing specific standards of analysis. The results of the study are as follows. The overall structure of the thesis is aimed at showing the 'Prevention-Therapy-Rehabilitation' quality of comprehensive health care and consists of six chapters; I. Prevention and Health Promotion II. Evaluation and Management III. Diagnostic Procedures IV. Endoscopy V. Therapeutic Procedures VI. Rehabilitation Chapter three Diagnostic Procedures is divided into four parts : Functional Diagnosis, Visual Diagnosis, Pathological Diagnosis, Biopsy and Sampling. Chapter five Therapeutic Procedures is divided into Psychiatry, Non-Invasive Therapy, Invasive Therapy, Anaesthesia and Radiation Oncology. Of these sub-divisions, Functional Diagnosis, Biopsy and Sampling, Endoscopy and Invasive Therapy employs the anatomical system of classification. On the other hand, Visual Diagnosis, Pathological Diagnosis, Anesthesia and Diagnostic Radiology, namely those divisions in which there is little or no overlapping in services with other divisions, used the classification system of its own division. The classification system introduced in this thesis can be further supplemented through the use of the cluster analysis by incorporating the advice and assistance of other specialists.

The impact of global warming on the south Asian summer monsoon is of critical importance for the large population of this region. This study aims to investigate the future changes of the precipitation extremes during pre-monsoon and monsoon, across this region in a more organized regional structure. The study area is divided into six major divisions based on the Köppen-Geiger's climate structure and 10 sub-divisions considering the geographical locations. The future changes of extreme precipitation indices are analyzed for each zone separately using five indices from ETCCDI (Expert Team on Climate Change Detection and Indices); R10mm, Rx1day, Rx5day, R95pTOT and PRCPTOT. 10 global climate model (GCM) outputs from the latest CMIP6 under four combinations of SSP-RCP scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5) are used. The GCMs are bias corrected using nonparametric quantile transformation based on the smoothing spline method. The future period is divided into near future (2031-2065) and far future (2066-2100) and then the changes are compared based on the historical period (1980-2014). The analysis is carried out separately for pre-monsoon (March, April, May) and monsoon (June, July, August, September). The methodology used to compare the changes is probability distribution functions (PDF). Kernel density estimation is used to plot the PDFs. For this study we did not use a multi-model ensemble output and the changes in each extreme precipitation index are analyzed GCM wise. From the results it can be observed that the performance of the GCMs vary depending on the sub-zone as well as on the precipitation index. Final conclusions are made by removing the poor performing GCMs and by analyzing the overall changes in the PDFs of the remaining GCMs.
