최근 모듈러 건축물 관련 연구가 활발하게 진행되고 있으나, 실제 건설산업에서 모듈러 건축물을 활용한 건축공사의 발주는 아직 활성화되지 못하고 있다. 이에 대한 여러 가지 원인들이 분석되고 있으나 그 중 중요한 것은 모듈러 건축물은 기존 현장중심의 건설생산체계를 공장제작-운송-현장설치 새로운 체계로의 전환을 요구하고 있다는 것이다. 하지만 국내 공공공사의 기존 발주방식은 전기통신공사업 등 개별법에서 분리발주를 의무화하고 있기 때문에 모듈러 건축물 장점을 살릴 수 있는 새로운 건설생산체계를 수용하기 어렵다. 따라서 기존 발주방식은 모듈러 건축물을 현장중심의 공사로 분리발주(건축 토목, 전기, 통신, 소방 등) 계약할 수밖에 없고, 건축 토목공사의 계약 범위 안에서 모듈러 유닛을 물품으로 구매할 수밖에 없기 때문에 이러한 분리발주로 인한 모듈러 건축물의 공장제작 비율을 저하시키고 공사비 상승, 품질저하 등의 문제를 발생시켜서 모듈러 건축물의 장점을 발휘하지 못하도록 하는 장애요인이 된다. 본 논문에서는 모듈러 건축물에서 요구하는 새로운 건설생산체계를 적극적으로 수용할 수 있는 새로운 발주방식을 개발하여 제안하고자 한다.

The development of an appropriate public service quality model has become increasingly recognised as an important subject of interest in the public sector as well as academia. In particular, the public systems enacted by governments are widely used and have a significant impact on national competitiveness. But few researches have been conducted to explore the quality dimensions of a public system service and empirically examine the relationship among related variables. Therefore, in this study, we strive to develop a quality measurement model of public system service that can be effectively used in practice. Using 601 samples gathered through a structured survey from project engineers, a conceptual quality model of public system is presented and discussed. Given the exploratory nature of this study, an exploratory factor analysis is used to investigate quality dimensions and partial least square (PLS) is employed in determining the structural relationships. From empirical results, we found that the quality dimensions of the public system had four distinct quality dimensions (design quality, environment quality, primary outcome quality, additive outcome quality). All four quality dimensions showed good representative factors in explaining user satisfaction. Perceived trust was proved to significantly mediate the relationship between quality dimensions and user satisfaction. Our research is expected to contribute to the literature by providing a good conceptual framework for assessing public system quality by linking four quality dimensions with user satisfaction. In particular, the developed model can elaborately measure process quality and multi-functional outcome quality of the system by the supplementation of design quality and additive outcome quality respectively. Practical implications are also suggested on the basis of our analysis.

최근 국내 도시개발에 있어 도시재생사업의 재원조달기법으로 세입담보금융의 도입이 검토되고 있다. 이러한 미래의 수익을 담보한 새로운 재원조달기법의 도입 가치는 단순히 개발재원에 대한 자가재정조달 방안이 아닌, 도시개발사업의 선순환적 구조형성의 가능성을 높이는 잠재성과 함께 고려되어야 한다. 이는 민간자본의 주도로 이루어지는 국내 도시개발사업의 구조적 문제점에 대한 대응으로서 사업초기 공공부문의 재원투입으로 개발과정내 공공부문의 주도적 역할을 강화하며, 이를 통해 공공을 위한 사회적 가치의 증대와 개발사업자의 개발이윤을 동시에 확보하기위한 구조적, 제도적 뒷받침을 가능하게 한다. 이에 본 연구는 미국 도시개발 사업에서 적용된 세입담보금융의 대표적인 형태인 TIF에 대한 이론적 고찰을 통해 세입담보금융의 일반적 특성을 파악하고, TIF와 구조적, 개념적 특징을 공유하는 독특한 형태의 적용사례인 PILOT을 뉴욕시 허드슨 야드 개발을 중심으로 분석한다. 이를 통해 세입담보금융의 국내적용에 대한 제안사안을 중심으로 참조 가능한 시사점을 도출한다.

Data plays an ever greater part in the tourism industry. While the platform-based sharing of open public data, private-sector intermediary platforms, and the use of social media to understand consumer trends are already well recognized, more potential for innovation exists in sharing private data among organizations in Smart Tourism Destinations. Research into the factors enabling and hindering coopetition in this kind of data sharing platforms is still in the nascent stage of development. Our case study of Sapporo, a major Japanese city endeavouring to create itself as a Smart Tourism Destination, sheds light on the initial approaches to involve organizations to such a data sharing agreement. Founding on seven interviews with ten participants of Sapporo Smart City project organization (SARD), we derived enablers and impediments that promote coopetition in data sharing as part of Smart Tourism Destination development. We also present practical recommendations and future research opportunities for such initiatives.

This study is designed to analyze the trends of professional services in Landscape Architecture during the past 5 years(1987-1991) in Korea. The data were collected from 1,117 projects from 56 engineering and landscape architecture firms. The findings are summarized as follows: 1) The projects have been increased annually by 19 percent in numbers and by 47 percent in money terms. 2) The main sources of projects are local governments and corporations. However the private sector comprise 31 percent in projects number and 46 percent in money terms. 3) The public park and tourism site development comprise a half of the projects. Recently recreational forest, golf, amusement and large housing site development have increased very rapidly. 4) In terms of workscope they are devided by 'complex' project which include extensive engineering works and 'simple' project which contain mostly planting design. The former include receational project with average 5 or 6 months contract period, and the later include housing and building site design with 2 or 3 months period. 5) Two types of consulting firms are typical. One is comprehensive engineering firms with urban planning section and few landscape section. The other is specialized professional firms with urban planning or landscape architecture. 50 percent of the project was done by comhensive engineering firms and 60 percent was done by urban planning section. The implication of these findings are broad: Firstly, We have to meet the demands in private secter mostly in recreation and leisure related projects. Secondly, landscape architects and project managers need more professional skills and coordination ability to deal with 'complex' projects. Thirdly, to enhance the quality of professional services it is required to have enough work time and higher service fee through legal and institutional enforcements.

Consultant and owner play a very important role in the construction sector which is one of the main sectors in economic development. There are many stakeholders in a construction project including but not limited to: owner, consultant, contractor, subcontractor, and supplier. The consultant is the party who is to stay in close touch with the project owner, which both consultant and owner are considered as the main key stakeholders to make the project happen. It's not a simple task for a consultant to just implement the same style of management and control within various projects that are of a different background and character of owners. Thus, the adjusting plan management and control to the owner environment has been an essential technique to drive the project to success. The objective of this paper is to identify the significant management techniques for adjusting a plan of management and control to the owner environment in Thailand. The methodology is the identification throughout the analogous to abduction from literature review and our empirical observations of Future Engineering Consultants Co, Ltd. We have been in consultation for twenty-five years (25) in Thailand with 209 projects from both public and private owners. As a result, there are (1) Project management styles, (2) Personal style, (3) Owner expectation management, (4) Scope Management, (5) Time Management, (6) Cost Management, (7) Quality Management, and (8) Environmental Management. The input are: a clear defined goal, showing respect by giving good service, maintaining high quality, keeping in touch with owners, and resources. This would give the output of the project's success by meeting the owner's expectation and requirements.

Purpose: The purpose of this study is to analyze air quality and carbon emissions in developing countries, particularly Myanmar, and explore the impact of transportation on CO2 emissions during peak hours relative to free-flow conditions. Method: This study conducted a traffic survey in two major cities in Myanmar to quantify carbon dioxide emissions from the transportation sector, using IPCC's tier 1 and tier 2 approaches, with statistical analysis performed using Python 3 and Microsoft Excel for comparative analysis of critical factors in CO2 emissions. Result: The result of this study is an estimate of the vehicle kilometers traveled (VKT) and fuel consumption in Yangon city for the year 2019, based on data from various sources including the Myanmar Statistical data base, YUTRA project survey, and Ministry of Electric and Energy. The study also analyzes the average travel time index (TTI) for the four roads in Yangon, which indicates the impact of congestion on vehicle travel time and CO2 emissions. Overall, the study provides important insights into the transport sector in Yangon city and can be used to inform policies aimed at reducing greenhouse gas emissions and improving traffic conditions. Conclusion: The study concludes that congestion plays a significant role in increasing fuel use and emission levels in the road transport sector in Myanmar. The analysis provides valuable insights into the impact of the sector on the environment and emphasizes the importance of addressing congestion to reduce fuel use and emissions. However, the study's scope is limited to Yangon city and Mandalay city, and some mean values may not accurately represent the entire country and other developing countries.
