EVMS(Earned Value Management System)는 사업을 관리하는 정부나 사업을 수행하는 업체의 관리자들이 비용과 일정을 주기적으로 추적함으로써 현재의 사업진행 상태를 파악하고 미래를 예측할 수 있는 관리기법이다. 이 관리기법은 미국, 호주 등에서 국방연구개발 사업에 의무적으로 적용해오고 있으며, 그 효율성이 이미 입증된 기법이다. 그러나 외국에서 수행하고 있는 EVMS를 그대로 우리나라에 도입하는 것은 환경적 차이로 인해 많은 문제점을 가지고 있기 때문에 우리나라에 환경에 적합한 EVMS 적용을 위해 연구를 꾸준히 수행하고 있다. 본 논문에서는 먼저 EVMS에 대한 개념을 먼저 고찰 해보고, 저자가 직접 관리하고 있는 차기경구난차량 연구개발사업에 적용한 EVMS 적용실태 분석을 통해 문제점을 도출하고자 한다.

「국유재산법」 개정으로 국유지 활용여건이 개선되었다. 새정부도 민간투자활성화와 재정투자 여력 확보를 위해 국유지 활용 필요성을 제시하고 있다. 본 연구는 이러한 정책기조 변화에 맞춰 일본의 국유지 활용정책과 유효활용 사례를 살펴보고 국유지 관리와 활용증진 관점에서 정책적 시사점을 찾아 보고자 하였다. 일본의 국유지 활용정책 방향은 효율적인 국유지 관리를 통해 보유 중인 국유지의 최적이용을 유도하며, 국·공유지 연계와 민간참여 등을 통해 적극적인 국유지 활용을 도모함으로써 국유지 가치를 높이고 미이용 국유지를 감소시킴으로써 궁극적으로 저가에 국유지가 매각되는 것을 억제하는 방향으로 정책이 추진되고 있는 것으로 나타났다. 국유지 유효활용 촉진을 위해 먼저 명확한 정책 방향을 정립하는 것이 필요하다. 그리고 투명한 정보공개시스템 구축, 부처간 이해관계 조정이 가능한 강력한 컨트롤타워 구축이 요구된다. 효율적인 국유지 활용을 위한 정책수립의 출발점은 실질적인 국유지 주인은 국민이라는 인식의 전환이다.

The main problems of disordered and congested urban landscape are due to the lack of holistic management that can control various elements of forming a city. Especially, the color of urban landscape is problematic because it is related to individual and social characteristics as well as to physical characteristics. Therefore, temporary expedients that can solve only visualized problems can not be a proper solution for color problems of urban landscape. This study originated from the question about why the color of disordered and congested urban landscape has not been improved. This study aims at directly improving the urban environmental color by finding out what the actual problems related to color are, and what the solutions would be. The goal of this study is to find a holistic systematic problem-solving method. Problems of urban environmental color are identified from both literature review and questionnaires to the expert group, such as environmental planning, design group, and the landscape executive group. Through mapping of relationships among these problems, the intellectual map was made to layout the structures of problems. Based on this method, the structures of problems of urban environmental color were classified into 5 categories: 1) the items related to the administrative structure, 2) the items related to the color management goal and system, 3) the items related to the color planning and design phase, 4) the items related to the color consulting committee, and 5) the items related to the present state of color use. Thus, in order to solve the color problem in urban landscape, practical strategy is strongly required. It is not a temporary expedient but a holistic approach. The solution for the problems of urban environmental color could be divided into 6 types; ‘regulations amendment’,‘color standard amendment’,‘color management plan’,‘color education’, and ‘advertisement for the goal of color management’. Regulations amendment among these types was proposed as the most effective method due to the close relationship with problem categories. Thus, as the solution for the problems of urban environmental color, the ‘color management system’ was suggested. Detailed contents the suggested color management system were divided into three parts; 1) legislation by regulations, ordinance and acts, 2) management by controling the level of guidelines, and 3) the standards for execution of this system.

In this paper, we present the section load estimation program of distribution system for smart distribution management system. The proposed program is composed with three parts. One is the consistency check part for switch measurements which consist a section. The consistency check is divided into the current and angle test. For the current test, we examine the input and output power flow for the switch group. For the angle test, the result of power flow calculation at previous step is used. Another is the voltage estimation part for the measured switches. We use the weighted least square (WLS) method for the voltage estimation. The third is the part of final section load calculation. The database structure for accomplishing the developed estimation program is also proposed. To verify the accuracy of the experimental results, case studies are performed using a actual data of Jeju island. The developed program can be effectively applied to the distribution operation systems.

This study examines the factors influencing the use of mobile food ordering applications and their impact on consumption behavior amidst recent societal changes. It re-evaluates the relevance of factors from the UTAUT2 theory in predicting customers' behavioral intentions. Additionally, the study explores the moderating effect of confidence in food safety measures (CFSM). Quantitative research methods are employed. A structured questionnaire that measures the psychological factors, behavioral intention, and actual usage of mobile food ordering applications was used to collect customer data. Regression and moderation analyses are conducted to test the hypotheses and examine the moderating role of CFSM. The findings reveal that performance expectation, effort expectation, and habit significantly predict customers' intention to use mobile food ordering applications. Moreover, for customers with high CFSM, social influence, facilitating conditions, and hedonic motivation add additional contributions to their behavioral intention. This study extends the UTAUT2 theory by applying it to mobile food ordering applications and examining the influence of CFSM. It identifies the specific factors that drive customers' intention to use these applications and highlights the importance of CFSM as a moderating factor. The findings offer theoretical insights and practical implications for researchers and practitioners in the mobile food ordering industry.

High-rise construction sites, especially those situated in spatially constrained urban areas, have difficulties in timely delivery of materials. Modern techniques such as Just-in-time delivery, and use of information technology such as Project Management Information System (PMIS), are targeted to improve the efficiency of the logistics. Such IT-driven management techniques can be further benefited from state-of-the-art devices such as Radio Frequency Identification (RFID) tags and Ubiquitous Sensor Networks (USN), which has resulted in notable achievements in automated logistics management at the construction sites. Based on those achievements, this research develops USN hardware toolkits for construction lifts, which aims to be automated the vertical material delivery by sensing the material information and routing it automatically to the right place. The gathered information from the sensors can also be used for monitoring the overall status. The developed system will be tested in the actual high-rise construction sites to assess the system's feasibility. The proposed system is being implemented using Zigbee communication modules and RFID sensor networks which will communicate with the intelligent palette system (previously developed by the authors). To support the system, a lift-mountable intelligent toolkit is under development. Its feasibility test will be conducted by applying the implemented system to a test bed and then analyzing efficiency of the system and the toolkit. The collected test data will be provided as a basis of autonomous vertical transport equipment development. From this research, efficient management of the material lift is expected with increased accuracy, as well as better management of overall construction schedule benefited from the system. Further research will be expected to develop a smart construction lift, which will eliminate the need for human supervision, thus enabling a real 'autonomous' operation of the system.
