One hundred ninety-five countries reached agreement on a new climate treaty in Paris, France to reduce the carbon emissions. South Korea has been selected as a target country for reducing greenhouse gas (GHG) obligations since 2020. In this context, the Korean government developed several GHG emissions reduction programs using forests called the "Forest carbon offset scheme (FCOS)." The forest management method is one of the tools to implement FCOS. Most of the participants registered forest management as the preferred methodology to participate in the FCOS. For a successful implementation of the FCOS, it is necessary to explore the optimal methods by considering the cost-effective aspect of conducting the forest management as a tool to increase carbon absorption. In this context, this study investigated the value optimized FCOS projects based on the forest management methodology in South Korea. Three forest management scenarios, 1) extending the final age of maturity of Pinus densiflora stands (S1), 2) extending the final age of maturity of Quercus acutissima stands (S2), and 3) reforestation with new species (Pinus densiflora to Quercus acutissima) (S3), were examined and evaluated to identify the optimal carbon absorption and value optimized economic perspective. The results of the scenario-based modelling indicated that S3 showed value optimized from an economical perspective, and S2 was the most effective method to absorb carbon among the scenarios. It is anticipated that this paper will contribute to provide valuable information by presenting innovative approaches as a value optimized FCOS implementing tool in a GHG reduction program in South Korea.

This study examines the relationships between R&D investment and Market value of Firms using data of small and medium enterprises (SMEs) in the manufacturing sector of Korea. In particular, this paper investigates the role of technology innovation system in the impact of R&D investment on firm's Market value of Firms. Findings from the previous studies on the relationship between R&D investment and Market value of Firms are positive relationship. Main of the previous studies demonstrated a positive impact of R&D investment on Market value of Firms. On the other hand, some recent studies showed this is not the case. Those studies persisted that the technological innovation system for managing and efficiently utilizing R&D investment and capability has to be built in order for R&D investment to give rise to increases in Market value of Firms. According to the Oslo manual by OECD, it is assumed that a technology innovation system can becharacterized as three factors :capability for technological innovation, capability for technology commercialization, capability for technological innovation management. This study divides sample firms into two groups using the "Inno-Biz" certificate system of the Korean Small and Medium Business Administration (SMBA): Inno-Biz firms Vs. Not Inno-Biz firms. The system selects innovative SMEs denoted as "Inno-Biz" using the above factors as criteria. The results revealed that the technology innovation system has the moderating effect to R&D investment on Market value of Firms.

Purpose - This study focused on consumers' perception about regulations for sales enforced by national and local governments in Korea. The study examined the relationship between perceived regulatory restrictions and subjective well-being (SWB), and perceived regulatory restrictions and shopping value, respectively. Research Design, Data, and Methodology - Data were collected from 135 college students and consumers in Gyeonggi Province to verify the relationships, moderating effects, and mediating effects, thus testing the theoretical model and its hypotheses. Results - First, consumers' positive perception of regulatory restrictions enabled enhancement of their SWB. Second, consumers' positive perception of regulatory restrictions had no significant positive influence on hedonic value but had a significant positive influence on utilitarian value. Third, utilitarian value exhibited a full mediating effect on the relationship between regulatory restrictions and SWB. Conclusion - This study showed that consumers' positive win-win attitude is based on social norms. Further, we expect that consumers experiencing discomfort due to regulatory restrictions resolve this by going to other distributors. Finally, to increase distributors' competitiveness and consumers' utilitarian value, it is suggested that distributors require a variety of marketing strategies.

Purpose - This study attempted to identify the value promotion clues that may operate as a consumer's motive, by shedding new light on consumer value and by reconstructing each variable analyzed through the means-end chain (MEC) theory. Research design, data, and methodology - In this study, 202 copies of effective questionnaires using the data of Yang and Ju (2012) were subjected to correlation, regression, and SEM. Results - All store selection attributes were verified as having a positive influence on the relationship quality. Although the store selection attributes were verified as exerting a positive influence on the relationship quality, according to the verification result of the mediating effect, consumer value was verified to be influenced only by the relationship quality instead of by the store selection attributes. Conclusion - As a result of path analysis on the proposed model after modification, it was verified that only product factor had a statistically significant positive influence and that social value was completely mediating between relationship quality and emotional value. It may be highlighted that the MEC theory concept would be applicable to the cause-and-effect relationship model.
