This study aims to analyze various issues and problems in the implementation process of cultural impact assessment in 2016. As a result of the analysis, it is found that the evaluation index of the cultural impact assessment is difficult to understand, and the referring data and materials in the evaluation planning phase in the process of the cultural impact assessment are deficient, and the evaluation planning is based on surveys rather than various methods. And there are some problems with evaluation scales and weighting, and they are focused on the evaluation itself rather than the feedback of the evaluation results. Therefore, this study suggests that, in the evaluation planning phase, the different methods of comparing the evaluation results according to the project execution, the project progress, and the completion time of the project should be adopted, and the project manager and the evaluation group participate developing the evaluation indicators together, and methodology for identifying causal relationship such as system dynamics will be adopted. In the stage of evaluation, it is necessary to introduce various methodology such as diverse residents participation, abundant case study, application of quantitative methodology, and the utilization of expert evaluation teams. In the evaluation feedback stage, it is necessary to provide thorough consulting based on the evaluation results.

As the number of cases of applying IT systems to the existing isolated ICS (Industrial Control System) network environment continues to increase, security threats in the ICS environment have rapidly increased. Security threat scenarios help to design security strategies in cybersecurity training, including analysis, prediction, and response to cyberattacks. For successful cybersecurity training, research is needed to develop valid and reliable security threat scenarios for meaningful training. Therefore, this paper proposes a case-based security threat scenario development methodology for cybersecurity training in the ICS environment. To this end, we develop a methodology consisting of five steps based on analyzing actual cybersecurity incident cases targeting ICS. Threat techniques are standardized in the same form using objective data based on the MITER ATT&CK framework, and then a list of CVEs and CWEs corresponding to the threat technique is identified. Additionally, it analyzes and identifies vulnerable functions in programming used in CWE and ICS assets. Based on the data generated up to the previous stage, develop security threat scenarios for cybersecurity training for new ICS. As a result of verification through a comparative analysis between the proposed methodology and existing research confirmed that the proposed method was more effective than the existing method regarding scenario validity, appropriateness of evidence, and development of various scenarios.

This paper examines whether the TFP growth of the Korean economy slowed down in 2000s based on growth accounting, focusing on how sensitive the results are to the particular aspects of the growth accounting method. There has been no consensus on this issue as the previous studies have provided very diverse results due to the differences in the details of the growth accounting method. Main results of this paper are as follows. First, it is how to calculate the labor income of the self-employed that has the most significant impacts on the estimated TFP growth. Measuring capital stock also matters. Second, the TFP growth of the Korean economy appears to be sustained in 2000s when the extreme assumptions on the labor income of the self-employed are excluded and capital stock is measured by the most frequently-adopted method in the previous studies. For more reliable estimation of the TFP growth, further studies on measuring the labor income of the self-employed are needed.

영광 3,4호기 노심보호연산기(CPC)와 노심감시계통(COLSS)의 운전성 시험은 실시간 (on-line)으로 측정된 노심보호연산기 및 노심감시계통의 결과들(DNBR, LPD, DNBR 출력제한치, LHR 출력제한치)을 노심보호 연산기 및 노심 감시계통 각각의 시뮬레이터 시스템(CEDIPS/CPC FORTRAN, COLSS FORTRAN)의 계산 결과와 비교하여 그 타당성을 검증하는 것이다. 그러나 기존의 노심보호연산기 및 노심감시계통의 운전성 시험자료 취득 방법은 관측(CPC)과 상세 보고서(COLSS)에 의한 것으로 정확한 자료 취득에 어려움이 있고 많은 시간이 소요되며 또한 자료 취득시 실수유발 가능성이 높다. 따라서 본 연구에서는 발전소 전산계통(Plant Computer System)으로부터 발전소 운전 상황을 순간적으로 기록한 자료(Snapshot)를 취하여 노심보호 연산기 및 노심감시계통 운전성 시험에 필요한 자료를 자동으로 얻는 방법을 고안하였다. 또한 발전소 Snapshot으로부터 필요한 자료를 자동으로 얻어내기 위하여 컴퓨터 프로그램(CODAP)도 개발하였다. 본 연구에서 고안된 방법은 영광 3호기 1주기 CPC/COLSS 운전성 시험에서 검증이 되어 영광4호기 1주기에 적용하였고, 이후의 후속기에도 적용할 예정이다.

Radioactive contaminant from a nuclear facility moves to the ecosystem by run-off or groundwater flow. Among the two mechanisms, contaminant plume through a river can be easily detected through a surface water monitoring system, but radioactive contaminant transport in groundwater is difficult to monitor because of lack of information on flow path. To understand the contaminant flow in groundwater, understanding of the geo-environment is needed. We suggest a method to decide on monitoring location and points around an imaginary nuclear facility by using the results of site characterization in the study area. To decide the location of a monitoring well, groundwater flow modeling around the study area was conducted. The results show that, taking account of groundwater flow direction, the monitoring well should be located at the downstream area. Also, monitoring sections in the monitoring well were selected, points at which groundwater moves fast through the flow path. The method suggested in the study will be widely used to detect potential groundwater contamination in the field of oil storage caverns, pollution by agricultural use, as well as nuclear use facilities including nuclear power plants.

This paper aims to explore the historical characteristics of CESE (Comparative Education Society in Europe) and BAISE(British Association of International and Comparative Education) through the analysis of their theoretical discourses which have impacted on Korean Society of Comparative Education. Inaugurated in 1963 by UK scholars, CESE is an ongoing international educational society beyond Europeanization. It seems intellectually struggling for setting up its peculiar comparative methodology discriminated from Americanization of method in general, because a long tradition that Europe is the center of the world has been shrunk by the emergence of WCCES led by US. While BAICE, inaugurated in 1997, is floating an international association with international students coming from overseas countries, tackling the global issues actively and making more balances with a critical equilibrium theories.

The purpose of this study is to suggest development directions and elicit future research themes of U-City and future city by identifying the research trends of U-City theses. For this, meta-keywords were elicited based on the theses of U-City and future city published from mid 1990s to 2010. Centered on the meta-keywords, temporal keyword analysis was performed to compare the research trends of U-City and future city theses in Korea and oversea. The results show that most of U-City and future theses in Korea and oversea mainly dealt with technology. U-City theses in Korea have a tendency to research technology, methodology, service, planning and management in order from the early beginning. However, the U-City and future theses in oversea have a tendency to continuously study U-City applications to city through the model based on the technology and methodology. Therefore, the U-City research in Korea should focus on aspects of urban regeneration, urban scale, and so on. That is to say, the research in near future is required to apply the U-City to various urban themes.

치수경제성분석, 투자우선순위 및 시설물 규모결정 등의 의사결정과정에서 실무에서는 다차원 홍수피해산정법(MD-FDA)을 현재까지 널리 사용 중이다. 2004년에 개발된 MD-FDA는 대상지역의 자산규모를 행정구역 경계 최소단위인 "읍면동"을 기준으로 계산하여 취합하고, 대상자산이 위치가능한 토지이용정보를 토지피복도로부터 확인하여, 읍면동내 토지이용공간면적을 기준으로 자산정보를 분배(분해)하는 방식으로 이루어진다. 그러나 읍면동 단위의 공간적인 범위는 상당한 면적의 공간적 경계이기 때문에, 이를 평균적인 밀도데이터로 분배 시 공간적인 자산분포에 대해 정밀도를 담보할 수 없다. 이에 본 연구는 행정구역경계인 "읍면동"과 비교할 때 평균적으로 1/30의 면적을 가지는 집계구 단위의 센서스 공간정보자료를 이용하여 방법론을 개선하였고, 이를 MD-FDA 분석체계를 근간으로 센서스자료와 관계된 자료들 간의 연계 및 전체적인 분석과정을 정립하였다. 본 연구에서 제안한 방법을 경기도 동두천시를 대상으로 적용하여 기존 방법에 의한 피해액과 그 차이를 비교하였고, 도로명전자지도의 실제 건물객체 자료(.shp)를 기준으로 오차율을 확인한 결과, 기존 방식에 비해 정밀도가 월등히 향상된 것을 확인할 수 있었다.

One of the major disadvantages of isogeometric analysis(IGA) is that local refinement is nearly impossible in a conventional manner because of the tensor product nature in NURBS. In this research, we investigate a local refinement scheme for isogeometric analysis, named multi-resolution approach where different resolutions are employed at each subdomain, using h-refinement relation to endow displacement compatibility on an interface of subdomains. Then, we develop shape sensitivity analysis possessing same compatibility condition as in the analysis. Numerical examples are shown to demonstrate the computational efficiency of the method in analysis especially stress concentration problem and accurate sensitivity results which is also compatible on the interface.
