최근 급속한 국내 건설환경의 변화속에서 기업은 구조개성을 포함한 다양한 변화를 추구하고 있으나, 이러한 노력이 경영 이익 증대까지 이어지지 못하고 있는 실정이다. 이러한 현상의 주요 원인 중 하나는 수주와 관련된 내 $\cdot$ 외부 환경변화를 기업의 경영전략과 조직구조에 반영하여 변화에 적응하고 더불어 수주성과를 극대화하기 위한 다양한 변화노력의 틀 속에서 진행되어야 함에도 불구하고 이와 같은 접근이 이루어지지 못하고 있기 때문이다. 특히 급변하는 환경에서 기업의 경영이익을 좌우하는 수주활동과 관련된 조직의 설계는 전반적 인 건설경기동향, 공공 및 민간의 발주 동향 등을 고려한 전략적이고 유연한 접근이 필요하다. 이에 본 연구에서는 수주환경 변화에 따른 수주조직을 전략적으로 설계할 수 있도록 환경변화와 경영성과측면의 관계를 규명하여 이를 대형건설업체의 사업유형 및 발주유형별 수주조직 설계에 반영할 수 있도록 모형과 절차를 제시하였다.

오늘날 과학과 경제 성장의 급속한 발달로 인해 많은 시설들이 건설되어 왔으며, 그 중에서 구조물들은 기술의 발달 및 제한적 공간의 효율적 사용으로 인하여 대형화 및 고층화가 가속되고 있는 실정으로 인해, 많은 구조물의 안전성 문제가 대두되고 있다. 특히, 과거의 노후화된 구조물은 유지 관리에 많은 인력과 예산이 필요하며, 구조물의 안전 상태를 손쉽게 모니터링 할 수 있는 기법의 개발은 시급하다고 할 수 있다. 그러므로, 구조물의 유지 관리 시스템은 구조물을 보다 효율적으로 관리하여 구조물의 내구성과 안전성을 증가시키며, 구조물 거동 시스템은 효율적인 유지관리 차원을 위한 경제적, 기술적인 결정체라 할 수 있다. 따라서, 본 연구에서는 위성을 이용한 GPS 측량방법으로 보다 경제적이고 정확한 자료를 취득하고, 구조물의 안전 상태가 자동 모니터링 되는 구조물 거동 경보 시스템을 개발하였다. 이렇게 개발된 구조물 거동 시스템은 구조물 거동의 절대 변위를 측정하여 구조적 변형,손상 감지등을 지속적으로 모니터링 함으로써 신뢰성과 안전성을 증진시킬 수 있을 것으로 기대된다.

Purpose: The purpose of this study was to identify the knowledge structure of health information (HI) for chronic obstructive pulmonary disease (COPD). Methods: Keywords or meaningful morphemes from HI presented on five health-related websites (HRWs) of one national HI institute and four hospitals, as well as HI needs among patients presented in nine literature, were reviewed, refined, and analyzed using text network analysis and their co-occurrence matrix was generated. Two networks of 61 and 35 keywords, respectively, were analyzed for degree, closeness, and betweenness centrality, as well as betweenness community analysis. Results: The most common keywords pertaining to HI on HRWs were lung, inhaler, smoking, dyspnea, and infection, focusing COPD treatment. In contrast, HI needs among patients were lung, medication, support, symptom, and smoking cessation, expanding to disease management. Two common sub-topic groups in HI on HRWs were COPD overview and medication administration, whereas three common sub-topic groups in HI needs among patients in the literature were COPD overview, self-management, and emotional management. Conclusion: The knowledge structure of HI on HRWs is medically oriented, while patients need supportive information. Thus, the support system for self-management and emotional management on HRWs must be informed according to the structure of patients' needs for HI. Healthcare providers should consider presenting COPD patient-centered information on HRWs.

Most internet companies in China are learning from Xiaomi Corporation's management model and to improving their organizational structures and human resource management practices. This study analyzed the development situation of Chinese Internet economy and the Internet thinking of Xiaomi which is a role model of Chinese Internet companies. In addition, we studied Xiaomi's organizational structure, human resource management, employee training, performance management and incentive system. In particular, Xiaomi's human resource management system has a great influence on the company's high performance and efficient service culture. Furthermore, the organization of Xiaomi is horizontally divided into three floors (7 key founders, department heads, and employees), each floor is managed by one founder. Xiaomi is interested in and considers not only the work of new employees, but also personal issues, and is concerned with the work of others in performance management and shares responsibility. Xiaomi adopts a unique and rational human resource management model, guaranteeing a lot of work autonomy for employees, and improving organizational performance.

The present study is to investigate the effect of wave-structure interaction such as wave oscillation. The theoretical method is based upon the linear diffraction theory obtained by the boundary element method. The water depth and incident wave period in fluid region are assumed to be constant. To investigate the wave interaction due to offshore structures, the numerical program has been developed and the simulation has been carried out by varying the conditions of distance and width of offshore structures. This study can effectively be utilized for safety assessment to various breakwater systems and layout of offshore breakwater in the ocean and coastal field. It can give information for the safety to construct offshore structure and revetment in coastal region.

The network structures of a hyperlinked environment can be a rich source of information about the contents of the environment and it provides effective means for understanding it. Recently, there have been a number of algorithms proposed analyzing hypertext link structure so as to determine the best authorities for a given topic or query. In this paper, we review the algorithm of mutual reinforcement relationship for finding hubs and authorities from World Wide Web, and suggest SHA, a new approach for link-structure analysis, which uses the relationships among a set of relative authoritative pages, a set of hub pages, and a set of super hub pages.

Few prior studies investigated the correlation between corporate ownership structure and environmental information disclosure. Using environmental index disclosure in GRI (Global Reporting Initiative) reports of the Korean companies, the study examines the effects of ownership structure on the magnitude of environmental information disclosure. A total of 220 firm-years during 2013-2016 period are analyzed. The empirical results of the study indicate that the institutional and foreign investors' ownership have positive correlations with environmental information disclosure, while the executives' within board of directors has a negative correlation. The ownership by largest shareholders including those with special interests shows no significant relationship with the environmental information disclosure.

There have been two streams of the studies on development structure : conceptual model approach and statistical analysis approach. But In these days, the latter has been becoming the main approach owing to the development of multivariate statistical methods and statistical packages. In this study, we examine methodologies and results of the leading researches related to development structure based on statistical analysis and propose the future research directions. This analysis would be expected to contribute toward the construction of long-range development policies on each country.

A tree structure model has been proposed for representing the unequal-area facility layout. Each facility has a different rectangular shape specified by its area and aspect ratio. In this layout problem, based on the assumption that the shop floor has enough space for laying out the facilities, no constraint is considered for a shop floor. Objectives are minimizing total part movement between facilities and total rectangular layout area where all facilities and dead spaces are enclosed. Using the genetic code corresponding to two kinds of information, facility sequence and branching positions in the tree structure model, a genetic algorithm has been applied for finding non-dominated solutions in the two-objective layout problem. We use three kinds of crossover (PMX, OX, CX) for the former part of the chromosome and one-point crossover for the latter part. Two kinds of layout problems have been tested by the proposed method. The results demonstrate that the presented algorithm is able to find good solutions in enough short time.
