This study performed an economic analysis and tested the viability of a public computerization project to create a comprehensive information system for public e-procurement for small and medium-sized businesses (SMBs). The study found that the estimated costs of the project included 4.3 billion won to build the system and 710 million won per year to maintain the system once it is built. The project's estimated total benefits amounted to 6.66 billion won per year, including 5.871 billion won per year in increased convenience for SMBs that use the system, 406 million won per year in benefits for public institutions, and 383 million won per year in benefits for the institution "A" to adopt the system. We used the contingent valuation method (CVM) to estimate the benefits to SMBs, which would be the main participants of the project. The survey found that the SMBs were willing to pay an average fee of 170,136 won. we conducted an economic analysis by applying a 5.5% social discount rate over an analysis period of 10 years and found a benefit-cost ratio of 5.02 and a net present value of 40.201 billion won, which indicated a very high economic viability of the project. The results of this study can be an important reference when deciding whether to pursue computerization projects in the public sector.

A public restroom is different from a household toilet in terms of location and a large number of sharing users. In addition, public restroom is usually messy and filthy. Recently, public toilet tends to be clearly managed than before, but it still has hygienic and clear problems. In this paper, we propose a machine-to-machine (M2M)-based public restroom management system to solve these problems, in which the system with a wireless communication device sends the status information of the toilet, such as blockage or trouble detected by a sensor, to the manager of the restroom at a remote location. In particular, we have developed a prototype management system for public restroom taking into account several system requirements, and verified the basic operations and performance of the management system. With the application of the system to public facilities, it will furnish users with more pleasant environments by restroom administrators who can respond effectively to the troubled toilet.

There is no prior research on organizational commitment and supervision for social welfare public officials in charge of public-private cooperation in public welfare fields. Therefore we are designed to determine the impact of social welfare public officials' public-private cooperation awareness on organizational commitment to verify the moderating effect of supervision on the effect between public-private cooperation awareness and organizational commitment. The analysis data is 242 questionnaires collected from Incheon public health and welfare officials visiting towns, villages, and villages in 10 counties. Using the SPSS 22.0 program, descriptive statistics and relationships between variables were analyzed, regression analysis was performed to analyze the influence between variables, and hierarchical regression analysis was performed to verify supervision control. As a result of the study, it was confirmed that the perception of public-private cooperation affects organizational commitment, interacts with supervision satisfaction, and has a moderating effect. Based on this, in order to improve the organizational commitment of social welfare public officials during public-private cooperation work, specific measures were proposed for sharing awareness and understanding between the public and private sectors, establishing an official system, and establishing a supervision system.

Procurement system of public construction projects in Japan is changing with diversity in rapid pace. The quality assurance and risk management of construction projects should be more certain as the projects are turning into larger scale and more complexed. The clients in the public sector will want to make the relation of responsibility among the client, the designer (architects and engineers), and contractor clearer in terms of role and risk. Public-Private Partnership (PPP) is one of the methods for collaboration of the public sector and the private sector in public construction projects where the public utilizes the ability and suggestion of the private. Private Finance Initiative (PFI), Design-Build-Operate (DBO), market testing, designated manager system, outsourcing of tasks in local governments are well-known as examples of PPP in Japan. Indeed, there is an obvious trend that Design-Build (DB) is adopted in public construction projects in many countries including Japan. In this paper, the public construction projects in various procurement systems are surveyed and analyzed. They are not limited within the traditional procurement, Design-bid-Build, a separate order system of design and construction. Design-Build or PFI are adopted. In particular, contract by wide range including maintenance of equipment can be found. On the other hand, modification from originally typical PFI is taking place, such as concept design and project finance are removed from the roles and the tasks of the special purpose company (SPC) in PFI. Standard roles and tasks in a construction project are modeled in this paper.

Most public guide robots installed in public spots such as exhibition halls and lobbies of department store etc., have poor capability to distinguish the users who require services. As to provide suitable services, public guide robots should have a human detection system that makes it possible to evaluate intention of customers from their movement direction. In this paper, a DPS (Directional Perception System) is realized based on face detection technology. In particular, to catch human movement efficiently and reduce computational time, human detection technology using face rectangle, which is obtained from the human face, is developed. DPS determines which customer needs services of public guide robots by investigating the size and direction of face rectangle. If DPS is adapted, guide service will be provided with more satisfaction and reliability, and power efficiency also can be added up because public guide robots provide services only for the users who expresses their intentions of wanting services explicitly. Finally, through several experiments, the feasibility of the proposed DPS is verified.

Recently, ever-growing land price has caused public projects to come to considerable deadlocks. Up to date, project principals have relied upon mandatory expropriation policy or other relevant policies in order to procure land sites required for public projects in a short period, but these policies have brought about collective resistances and civil appeals from land owners and cause land compensation price to rise, resulting in delayed progress of public projects. Therefore, land banking system is enforced to resolve these issues. Successful implementation of land banking system requires purchase of sufficient land sites at affordable price so as to execute public projects and control real estate market. However, current version of Land Banking Act reveals several questions as contrary to public expectations in the days of its introduction. This study sought to make further analysis on the whole content of current legal system concerning land banking system. And based on the analysis, this study explored possible solutions for problems that hinder land banking system from its stable operations, so that this land banking system could contribute to resolving land problems by active promotion of public projects as originally intended and by the stabilization of land market based on balance control between supply and demand of land.
