<P>Construction project is completed through several stages and problems of each stage affect directly not only now but also next. Defect of 2D drawings influence in construction phase, and it make many loss on project. Nowadays we practically use real Mock-up test in construction sites to solve the problems. But it also has many problems which are waste much money and time. Therefore, this study tries to analyze effect that is occurred by appling BIM Mock-up simulation instead of real Mock-up execution. These analysis is conducted by comparing two construction building site. These have same shape but one is made for BIM Mock-up, and another is real Mock-up. Comparison points of view are cost, time and operator‘s satisfaction. It is expect that BIM Mock-up is more effective at low cost and on shorter time.</P>

This paper provides theoretical deformation of lean concept and its application for usage of building information modeling(BIM) process. Recently, much research is focused on application of lean concept for more efficient usage of BIM. The leantheory and its basic function and feature is based on manufacturing industry. The manufacturing process can be improvedby process re-engineering steps of lean concept which consist of the steps of value, value stream, flow, pull, perfection. However manufacturing process and construction process has different characteristics. Due to the differences, five steps ofthe traditional lean’s process re-engineering can’t be directly applied to the BIM based engineering process. In order tosolve this problem, we conduct analysis on the characteristics of the manufacturing process and BIM based engineering. We propose modified and expanded concept of lean for process re-engineering and the modified theory was applied to themechanical, electrical and plumbing (MEP) coordination process. Through the proposed 8 steps of methodology, 2D basedprocess was changed to integrated and using BIM based MEP coordination process. In addition, the results showed thepotentiality of cost reduction and process improvement. The results of this study can be a foundation for the theoreticalcombination of lean and a variety part of construction engineering process. 이 논문은 프로세스 재설계 관점에서의 린 (lean) 개념의이론적 변형과 BIM 프로세스 개선 사례를 제시한다. 최근에는 BIM을보다 효율적으로 사용하기위해 린 개념을 접목하는 연구들이 증가하고 있다. 린 이론과 성격과 기능은 제조업을 기반으로 하며 제조업에서의 프로세스는 린 개념의 프로세스 재설계 과정에 의해서 변형된 하나 프로세스로 개선된다. 하지만 제조 공정과 건설 공정은 다른 특성을 가지고있다. 두 산업의 서로 다른 차이점으로 인해 전통적인 린의프로세스 재설계 기능의 5 단계에는 이론적으로 BIM 프로세스에 그대로 적용하기에는 어려운 단계들이 포함되어 있다. 본 연구는 부분적으로 적용되는 린 개념의 접목을 해결하기위해 제조 공정 및 BIM 프로세스의 특징을 분석했다. 이를통해 이론적으로 린의 프로세스 재설계 단계를 수정하고 확장했다. 변형된 프로세스 재설계 단계는 설비전기 설계조율프로세스에 적용했다. 본 연구에서 제안한 8단계의 프로세스 재설계 단계를 통해 일체화된 BIM 프로세스로 변형할수 있었다. 또한 사례연구 결과는 공정 단계의 감소 및 비용절감의 가능성을 나타냈다. 본 연구의 결과는 BIM 프로세스뿐만 아니라 다양한 프로세스에 접목될 수 있는 린 개념의이론적 기초가 될 수 있다.

Takayasu's arteritis is a common etiology of renovascular hypertension in orientals. We report a case of renovascular hypertension caused by Takayasu's arteritis in a 18 year-old male patient. The narrowed renal artery was treated by renal artery stenting and blood pressure was normalized after the procedure. Restenosis was suspected after 7 months follow-up because his blood pressure was elevated.(Korean J Med 62:289-292, 2002) 저자들은 18세 남자환자에서 Takayasu 동맥염으로 인한 신혈관성 고혈압이 발견되어 협착된 신동맥에 스텐트 삽입술을 시행하여 치료하였기에 이를 문헌고찰과 함께 보고하는 바이다.

Existing problem of 4D simulation is linking 3D model part to activity. These problem make lose of time and cost, construction simulation can not be used frequently. So, construction industry apply 4D simulation only for visualization in oder to media hype. For making best use of construction simulation, methods of automating process should be propesed. Therefore, this study tries to improve method of making 4D simulation. First, existing method were analyzed and strong point was abstracted. Next, two type of 4D simulation method are developed for pre-construction and construction phase. Additionally, conditions of 4D automation wereproposed.

Recently, the complication and large scale of the construction project have caused a lot of problems of cooperation and information sharing. There are many research activities based on techniques of the virtual construction system. For solving this problems, There are many research activities. But, the research, related on an equipment planning, is lacking for sharing and exchanging the information among participants of the project. Therefore, This paper is one of the researches for making an infrastructure of the equipment planning that is one of the virtual construction system. This paper is focused on Tower-Crane and should analyze the process for the selection of Tower-Cranes, through analysing proceeding researches and real construction sites, and Database ,previously using in BIM tools. As a result, making Database, based on real used Tower-Crane, import in BIM tools. Adopting of the Database based on actual Tower-Cranes enables participants to review expecting problems, which can reappear in real construction site, by building construction structures in a BIM system. This function could be used as an important tool of virtual construction system.

The aim of this study is to investigate the influence between self-leadership and leader-member exchange of hotel employees with 10 years or more experience on psychological empowerment and organizational citizenship behavior. Based on 126 samples collected from employees in 13 super deluxe hotels in Seoul for empirical study, a total 5 hypotheses were verified by a multiple regression analysis. The results of this study was as follows. First, self-leadership had significantly positive effect on psychological empowerment and organizational citizenship behavior. Progressive thought dimension had a positively influence on psychological empowerment, but self-management dimension did not have an influence on it. There was no significant statistical influence in sportsmanship dimension of organizational citizenship behavior, and self-management had a positive influence on organizational citizenship behavior. Second, quality of LMX had a significantly positive effect on psychological empowerment and OCB. Contribution dimension had a positive influence on psychological empowerment and OCB while emotional ties dimension had affected OCB only. And sportsmanship and altruism dimension did not have significant statistical influences on the relationship between LMX and OCB. Psychological empowerment had a positive effect on OCB. But there was no significant statistical influence in sportsmanship dimension. Competence and meaningfulness dimensions(and meaningfulness dimensions had a significant influence while personal influence did not. Based on these findings, the theoretical and empirical implications were discussed. The findings provide useful information for managements of hotels.

로컬 특징 기반 글로벌 이미지를 사용한 CNN 기반의 악성코드 분류 방법

장세준 ( Sejun Jang ),성연식 ( Yunsick Sung ) 한국정보처리학회 2020 한국정보처리학회 학술대회논문집 Vol.27 No.1

최근 악성코드로 인한 피해가 증가하고 있다. 악성코드는 악성코드가 속한 종류에 따라서 대응하는 방법도 다르기 때문에 악성코드를 종류별로 분류하는 연구도 중요하다. 기존에는 악성코드 시각화 과정을 통해서 생성된 악성코드의 글로벌 이미지를 사용해 악성코드를 각 종류별로 분류한다. 글로벌 이미지를 악성코드로부터 추출한 바이너리 정보를 사용해서 생성한다. 하지만, 글로벌 이미지만을 사용해서 악성코드를 각 종류별로 분류하는 경우 악성코드의 종류별로 중요한 특징을 고려하기 않기 때문에 분류 정확도가 떨어진다. 본 논문에서는 악성코드의 글로벌 이미지에 악성코드의 종류별 특징을 나타내기 위한 로컬 특징 기반 글로벌 이미지를 사용한 악성코드 분류 방법을 제안한다. 첫 번째, 악성 코드로부터 바이너리를 추출하고 추출된 바이너리를 사용해서 글로벌 이미지를 생성한다. 두 번째, 악성 코드로부터 로컬 특징을 추출하고 악성코드의 종류별 핵심 로컬 특징을 단어-역문서 빈도(Term Frequency Inverse Document Frequency, TFIDF) 알고리즘을 사용해 선택한다. 세 번째, 생성된 글로벌 이미지에 악성코드의 패밀리별 핵심 특징을 픽셀화해서 적용한다. 네 번째, 생성된 로컬 특징 기반 글로벌 이미지를 사용해서 컨볼루션 모델을 학습하고, 학습된 컨볼루션 모델을 사용해서 악성코드를 각 종류별로 분류한다.
