The purpose of this research is to examine whether investment portfolio composition affects the technological performance of corporate venture capital (CVC). The stages of investment are categorized from "start-up/seed", "early", and "expansion", to "later" stage. We posit and test that the investment stage composition in a portfolio is highly correlated with the growth potential and downside risk of the portfolio, which in turn influences an investor's innovation performance. To test this hypothesis, we used negative binomial panel regression with 21 years of deal data from 70 cases of CVC. The results show that there is an inverted U shaped relationship between investment portfolio composition and technological performance. This means that the more seed or early stage investment within the investment portfolio, the higher the innovation performance; however, if the amount of seed or early stage investment is over a certain level, the performance decreases. Further, this study finds that the external partners of a venture negatively moderate the inverted U shaped relationship between portfolio composition and innovation performance. We believe that corporate planners, venture capitalists, and policy makers will be helped by these results showing that companies can maximize their investment performance by considering the investment stage and progress of investments.
An ultramafic complex occurs as an isolated lenticular body in the Andong area. The Andong ultramafic complex comprises ultramafic and mafic rocks, but mainly peridotites. The complex extends for several kilometer to ENE direction, adjacent to the Andong fault line. This study is for petrochemistry of the peridotites within the ultramafic complex and characteristics of asbestos occurrences. The peridotites are igneous origin, ranging from lherzolite to wehrlites and are characterized by high Fo olivine ($Fo_{0.85-0.87}$), Mg clinopyroxene ($Mg_{87.5-93.5}$), and tremolitic to tschermakitic hornblende. Geochemically, these rocks show high magnesium number (mainly Mg = 85.3-87.38) and transitional element and low alkali element contents. The peridotites host asbestos, including chrysotile, tremolite and actinolite asbestos, but dominated by amphibole asbestos. The amphibole asbestos are found along small fault face, and cleavage and fracture showing several cm to ten cm in width as slip and oblique fibers, while the chryostiles occur at cleavage and vein showing several mm-cm in width as cross and slip fibers. They are confirmed by PLM, XRD and SEM results. Overall characteristics of peridotites from the Andong ultramafic complex and occurrences of the asbestos are similar to those of worldwide orogenic related Alpine type ultramafic rocks and serpentinized ultramafic bodies in Chungnam, Korea, respectively.
The purpose of this study is to analyze the present stage of community archives movement in the UK. By doing so, it draws some implications of the UK case for the community archives movement in Korea. The UK's 'Independent' community archives as a part of grassroots movement are characterized by participation, autonomy, and self-help of community members. Along with the appearance of the concept of 'community', the UK has experienced the revitalization period of community archives in the social context of community-based urban regeneration project. Recently, the UK's community archives have transformed themselves into building a 'governance model' relying on the partnership with mainstream archives. In particular, the UK model of community archives is based 'on their own ways' with their autonomy as a product of intrinsic development initiated by communities themselves. The character of the model of this type is very analogous to the nature of maul' community archives movement in Korea. Since the early 2000s, however, the UK model of community archives has been evolving into a way of building governance through their appropriation of the skills and methodologies from mainstream archives without endangering the autonomous essences of community archives themselves. We need to note the point of local researchers' view in archival science who have tried to seek out the methodology for building maul community archives with regard to openness and collaboration. In this respect, a shift in archival principle in the UK would give significant implications in regenerating the locally based community model.
In tidal flats that lack plants, methane ($CH_4$) fluxes are both positive (gas emission) and negative (gas "sinking") in nature. The levels of methanotroph populations significantly affect the extent of $CH_4$ sinking. This preliminary study examined $CH_4$ flux in tidal flats using a circular closed-chamber method to understand the effects of macroinvertebrate burrowing activity. The chamber was deployed over decapods (mud shrimp, Laomedia astacina and crab, Macrophthalmus japonicus) burrows for ~ 2 h, and the $CH_4$ and $CO_2$ concentrations were continuously monitored using a closed, diffuse $CH_4/CO_2$ flux meter. We found that Laomedia astacina burrow (which is relatively long) site afforded higher-level $CH_4$ production, likely due to diffusive emission of $CH_4$ in deep-layer sediments. In addition, the large methanotrophic bacteria population found in the burrow wall sediments has $CH_4$ oxidation (consumption) potential. Especially, nitrite-driven anaerobic oxidation of methane (AOM) may occur within burrows. The proposed $CH_4$-oxidation process was supported by the decrease in the ${\delta}^{13}C$ of headspace $CO_2$ during the chamber experiment. Therefore, macroinvertebrate burrows appear to be an important ecosystem environment for controlling atmospheric $CH_4$ over tidal flats.
The Calendar(曆法) has been a very important concern in every dynasty of history.『Hyupgiltongui』 written in the Joseon Dynasty included many contents related to the Calendar. In particular, the ancient rule of the Calendar(曆律) shown in the text of 『Hyupgiltongui』 Bonwon chapter one is meaningful in the process of creating the necessary Calendar for selection and reading fortune. Accordingly, we tried to analyze the rule of the Calendar(曆律) that is the fundamental principle of the Calandar(曆法) and the almanac which can be used in real life, based on comparative analysis of 『Hyupgibyeonbangseo』, 『Sanggiltongseo』 and 『Cheongidaeyo』, which are the basis of 『Hyupgiltongui』. Saju Myung-ri is the scheme of time change by the combination of Ganji (Celestial Stems). Therefore, the core of the calendar system is to make four pillars by the year, month, day, and time. For doing this, 『Hyupgiltongui』 provides basic principles and materials for making four pillars using constellations like 28 Fixed Stars, as well as does simple composition principle for telling fortune such as Ten Celestial Stems, Twelve Zodiac Signs, the order of four seasons(四序), Yukjin(六辰) and Sexagenary Cycle (甲曆). However, despite the limitations of the results produced by the rule of the Calendar(曆律), we came to the conclusion that if reading fortune in Saju(四柱簡明) is to find good one(吉) in terms of understanding it as the rule of predicting future(術法) not science, its usefulness cannot be ignored.
This paper pays attention to the recent increase of young Koreans working in the low-skilled service sector in Singapore. Such rapid increase largely results from the Korean government's initiatives to promote labour migration of young people and the concurrent proliferation of migration agencies, against the background of growing youth unemployment in South Korea. By exploring the motivations and trajectories of young people's labour migration to Singapore, this study examines to what extent they think their expectations have been met and how they interpret their migration and work experiences. There has been little research that examines the actual voices of young migrants as part of migration studies, whilst the majority of previous research focuses on the evaluation of government support programmes based on job matching rates, surveys of participant satisfaction and etc. Young people who went to Singapore to improve their English language skills and qualifications for future employment in Korea have become frustrated due to low-skilled service jobs that consist of low pay and high labour intensity. Their credentials are devalued and they experience deskilling through this migration process. Most of them were discontent with the Korean migration agencies they used and critical about programmes offered by government institutions and universities/colleges. Despite being subject to deskilling, they did try to actively cope or resist this situation. This study focuses on the various ways these migrants attempted to manage the gap between their initial expectations and reality. It also demonstrates how these migrants interpreted their work experiences after returning to Korea: whilst most of them did not cash off their Singapore work experience for a decent job after returning to Korea, they did not define their experience as a complete failure. Adding to cultural, social capital they gained through this experience, they acquired 'mobility capital' which includes confidence, the desire to move, and capacity to control one's own movement.

This paper investigates the causal impact of the increase in institutional distance between two geographic regions on the flow of cross-border Venture Capital (VC) between the regions. While cross-border VCs are believed to have competitive advantages at identifying and managing promising startups in a local market compared to local counterparts, the discrepancy in institutional characteristics between two markets exacerbates the difficulty of credible information exchange and negotiation, significantly increasing transaction cost related to a cross-border venture capital investment. This study conducts a difference-in-difference analysis to examine the relationship between institutional distance and the flow of cross-border VC investment using the fact that the official adoption of the Euro currency by member countries of the European Union except the UK created an institutional chasm between the UK and other EU member countries. The outcomes of the analysis suggests that UK-based VCs significantly decreased the VC investment into EU-based startups and that EU-based VCs reduced the investment into UK-based startups. The results have meaningful implications for understanding the impact of the change in institutional difference on cross-border VC investment, which seems to increasingly take place with the recent trend of de-globalization and the rise of protectionism.
Seoul is under increasing pressure to choose between the US-led IndoPacific Strategy (IPS) and China's Belt and Road Initiative (BRI). Accordingly, this paper undertakes a detailed appraisal of the IPS and the BRI in the context of Korea's national policy imperatives. Based on a study of network structure by Daniel Nexon and Thomas Wright (2007), the present study seeks to identify a particular network structure within the IPS and the BRI. Through this analysis, the relationship between the core and the participant states will be addressed. Awareness of specific configurations of the IPS and the BRI is important as these reveal what participant states can expect from each network. According to Nexon and Wright, there are four types of network structure: unipolar anarchy, hegemonic order, constitutional order, and imperial order. Based on this, we argue that the IPS has a constitutional order and the BRI has an imperial order. Therefore, we suggest to Seoul that participating in the IPS may make more room for an independent foreign policy than would a BRI partnership with China. South Korea would benefit by participating in the IPS in terms of its national security, striking a favourable regional balance of power.
The purpose of this study was to establish entrepreneurship(risk taking, proactiveness, innovativeness), entrepreneurial self-efficacy, and entrepreneurial intention as a structural equation model to confirm the entrepreneurial intention of university students. In order to achieve the purpose of this study, 449 students from 3 university students in Gyeonggi-do were studied, and data analysis was conducted with SPSS 23.0 and AMOS 23.0 statistical programs. The results of the empirical analysis are as follows: First, Among university students' entrepreneurship, proactiveness was not statistically significant to entrepreneurial intention but, risk taking and innovativeness have been identified as having a direct impact. Second, University students' entrepreneurial self-efficacy directly affects entrepreneurial intention. Third, risk taking and innovativeness were statistically significant, but proactiveness was not affected. Finally, through the mediating of entrepreneurial self-efficacy, risk taking effects were fully sold to entrepreneurial intention, and innovativeness was partially sold to entrepreneurial intention. Based on the results of this study, the way to enhance university students' entrepreneurial intention is to develop programs that can improve their entrepreneurial self-efficacy and apply them actively to university education. In particular, university students need mentoring support from on-site entrepreneurial experts and internship education support to increase risk taking and innovativeness as prospective founders. The government can lead to entrepreneurial behavior when economic and institutional support precedes university students to recover from their initial entrepreneur.

Based on the theoretical review of social cooperatives and the results of the fourth round of fact-finding, this study tried to discuss the sustainability of social co-operatives from the social, economic, and environmental aspects, focusing on the seven principles of co-operatives. The issue of sustainability is "a development that meets the needs of the present without compromising the ability of future generations to meet their own needs, the use of resources, the direction of investment, technological advances and institutional change in harmony with one another. as defined as "a process of change that advances the needs and desires of all future generations". It contains the meaning of connecting a sustainable society to future generations through harmony and balance, rather than opposing concepts of social value, environmental conservation, and economic growth. As a result of arranging the concept of social, economic, and environmental sustainability contained in sustainable development, and the seven principles of cooperatives and their connections, I would like to suggest the following about the sustainability of social cooperatives. First, efforts should be made for social contribution closely related to the local community. Second, it is necessary to create a profit model along with the public interest. Third, partnerships should be strengthened. When examining the public values and objectives that social cooperatives want to realize through this study, the three scopes of sustainable development are directly related to the role of important actors in pursuing social and economic values that social and economic organizations are facing. would. Therefore, the sustainability issue of social cooperatives is based on the concept that the goals and values pursued by social cooperatives are harmonious and balanced development in the environmental, social, and economic aspects, not only their own efforts but also the institutional support of the government. this will have to be presented.
