The fifty six components of volatile organic compounds(VOCs) were continuously measured by the hour to see the distributions their of its concentration and the ozone creating contribution of nitric oxides and VOCs in Gamjeon Odor and VOCs Monitoring Network from April to September, 2008. Aromatics occupied 51.3% of VOCs and paraffins, alkanes and olefins came in order. The monthly concentration of VOCs in Gamjeon was high in July and low in September. As for hourly concentration of ozone and nitric oxides, ozone started to increase since 10am having the highest in the daytime, and nitric oxides had the different trend from that of ozone, showing the lowest in the daytime. The photochemical ozone creating potentials(POCPs) of toluene, propane, m/p-xylene, ethylbenzene, and 1,2,4-trimethylbenzene were 30.6%, 10.2%, 9.4%, 7.4% and 5.2% respectively. These five components occupied 62.8% of total POCPs, which means they contributed to the ozone creation mainly. Related with the ozone creating contribution, the ratio of VOCs to NOx was generally under 6 occupied 72.0%, which came under the area coexisting the limit of VOCs. Therefore it is thought that the management of emission source of VOCs is very important for the reduction of ozone.

The government has been implementing the preliminary feasibility study to examine previously a plan of the national R&D program submitted by each government ministry or institution and decide whether to reflect its budget. However, although R&D investments obviously have a different contribution depending on the different types of project, the current system applies the average R&D contribution rate to whole industry across the board in order to estimate benefits of the creating value from the R&D activity. This system in turn will cause a distorted result in the economic feasibility analysis. Therefore, this paper conducts an empirical analysis on the ICT R&D contribution for the creating value added, on behalf of all industries, through the growth accounting method and explores an applicability of the differential R&D contribution rate as an alternative by comparing to the existing R&D contribution rate. The result of this paper shows the ICT R&D contribution rate is 48.2%, and we can find out there is a significant difference compared to the existing R&D contribution rate. In light of this, it is necessary to adopt carefully the differentiated R&D contribution rate considering project characteristics.

This study examined the importance of social contribution through the existing research data on social contribution and the progress of social contribution activities of public institutions in Wonju Innovation City. The social contribution activities of nine organizations out of 14 public institutions were analyzed in detail and suggested the right direction of social contribution activities of public institutions based on this analysis. First, recent trends are being developed to cooperate with local communities through public interest activities rather than simple donations or sponsored forms of social contribution. Second, the synergy effect was maximized by systematically approaching local communities rather than a one-time, one-off social contribution. Third, it should contribute to the revitalization of the local economy in the mid- and long-term by creating a social economy in cooperation with local civil society rather than a one-sided social contribution.

This study evaluated the contribution of carbon neutrality by calculating the carbon reduction amount and reduction intensity targeting the hydrogen pilot city and applying it to the carbon neutral reduction target. In the building sector, the reduction amount for 2030 was 10.8% on average. In addition, by 2050, the contribution to carbon neutrality of plan A was 14.1% on average, and the contribution to carbon neutrality of plan B was 15.1% on average. In the 2030 reduction amount of the transportation sector, the contribution to carbon neutrality was 138.4% on average. In addition, by 2050, the contribution to carbon neutrality in plan A was 82.5% on average, and the contribution to carbon neutrality in plan B was 74.9%. From the above research results, additional carbon reduction is possible when creating a hydrogen city, so it will be used as a basis of city-level carbon neutral model. It will also be used as a basis for technology development and investment promotion for various hydrogen supply methods in the future.

Science and Technology Park (STP) is perceived to be a vehicle in promoting innovation-based economic growth within the framework of regional and national innovation systems. STP is a tool to encourage regional innovation and competitiveness in increasing contribution of science and technology in economic development. STP can also be a leading sector in creating conducive environment for local community's technopreneurship. In relation to the vision outlined in the 2025 Indonesian Master Plan of Acceleration and Expansion of Indonesia's Economic (MP3EI), STP is stated to be an important element in creating innovation within the framework of Special Economic Zone among six Economic Corridors. Hence, the government of Indonesia continues to encourage the development of STPs in Indonesia by involving local governments, universities, business players and stakeholders surround the area. Ultimately, STP is a platform in developing National Innovation System (NIS) and Regional Innovation System (RIS).

The purpose of this study is for science and engineering students to experience social contribution through voluntary projects. The method of research is to create and introduce the exhibits and its exhibition commentary of Science Museum for local youth. The exhibition commentary is a project that stimulates student's interests in science and technology by providing scientific knowledge and research information. Producing exhibits is a project that discovers local technologies as well as introduces its history, technology, and scientific principles to young students. Two projects confirmed the positive effects of creating opportunities for science and engineering students to contribute to society and expanding scientific content, and showed implications for engineering education.

This study investigates the influence of consumer needs pertaining to brand social media pages on the consumer brand attachment formation process. We collected 278 valid responses from females who have experienced the food brands' social media pages. Following the data analysis, we developed the results as follows. First, we examined the significant influence of attachment to brand social media page needs and socialization needs on consumer content consumption engagement and content contribution engagement on brand social media pages. Then we determined that consumer engagement significantly influenced consumer brand attachment. Finally, we found consumer consumption engagement exerted a significant mediation effect on the relationship between consumer needs and brand attachment. Based on the results, we outlined the potential theoretical and marketing strategy implications of this research.

By the IMF condition, tax revenues of local governments are decreasing, under these conditions, container tax take important proportion in financial resources in Pusan Metropolitan City. However the container tax have time limit until 2001, that is, purposeful tax. But after the creating container tax, the level of accomplishment is very insufficient. So for the activation of local economy, we need active study on the existence problem of container tax. Though the abolition of container tax item is frequently discussed in central government, If the worst case comes, namely the abrogation, it gives big damages to the financial management of Pusan Metropolitan City. Therefore the container tax should be existent for both residents and local government. Because the expansion rate of container tax is so rapid, it makes very critical contribution to the stability and sound condition of Pusan Metropolitan City's finances.

Holography provides a medium for creative visual experiences in space and scale. It has been firmly established as a tool for scientific and engineering studies. It could be creatively used in interior architecture and display as a practical device and as a form of art. Basic principles and features of holography are explained. Design of the holographic systems are illustrated in some interior architectural applications. It is believed that holographic elements can make a valuable contribution to interior architecture design by controlling light and creating new concepts of colour and space.
