It was started that Shiwe-goon was organized from Shilla-end to Goryeo foundation a country in powerful families existence merely royal household by stably plan means in the reign of Taejo. Generally Shiwe-goon was dutie king' personal danger of protection. Shiwe-goon was organized castle of guarding, stand by king and royal household side armed strength to going on a trip and general armed-organization was collapsed for Goryeo-end continued existence. Goryeo era of Shiwe-organization was divided central army and region army. Two-goon(Eungyang-goon, Yongho-goon) was undertaken king of Shiwe army and six-we(Chunwoo-we, Geumoh-we, Gammoon-we, Jeoawoo-we, Shinoh-we, Hongwe-we) was undertaked capital of guard and the border of defense duty. Central army of commanders was called Sangjanggoon, Daejanggoon. Sangjanggoon and Daejanggoon was discussed military officer of conference apparatus in Jungbang. Jungbang was got afterward Mooshinjungbeon happened military of statesman grasping political power with authority a main stay. Mooshinjungkwen era was appeared modernistic mean of privately guarding organization in Dobang and Naedobang. According as Shiwe-organization was charged military organization as a part of sovereign power and grasping strength of authority- maintenance for security and guarding duty.

This study investigated any possible financial attributes of the CDS spreads of a firm belonging to financial industries headquartered in the Republic of Korea. There were few studies on this issue, especially for the firms located in emerging capital markets. Coupled with the models such as a multiple regression and a principal component analysis(PCA), this research has identified that only two explanatory variables such as SLOPE and INTER3 (i.e. interaction effect between the BETA and the SLOPE) consistently showed their statistically significant influence on the CDS spreads through the 'selected' model without and with applying a stepwise regression procedure for the robustness. Given the rapid developments of sophisticated financial derivatives, this study may suggest a valuable insight to foreign and domestic investors to identify the possible determinants of CDS spreads at the firm- and/or the industry-level.

This study attempted to analyze the relationship between school life satisfaction and acculturation of elementary students of north Korean refugees in Daegu and Gyeongbuk region. The socio-demographic characteristics of elementary students in Daegu and Gyeongbuk were different from in capital territory or other parts of Korea. The acculturation of students living in Daegu and Gyeongbuk was distinctive. The proportion of assimilation was slightly higher than that of integration. However, 42 percent of students belonging to separation and marginalization passively accepted south Korean culture, so that they would have a difficult time in adjusting to new culture. Students getting older and being used to school life strongly inclined to accept south Korean culture; while, students born in north Korea tended to resist acceptance of south Korean culture. Most students were satisfied with school life. The satisfaction level was high in the relationship with teachers and school environment; while, the satisfaction level in learning activity was relatively low. In the relationship between school satisfaction and types of acculturation, students actively accepting new culture were relatively highly satisfied with their school life. A standardized short-term education oriented program for north Korean adolescents refugees living in south Korea should be shifted into the long-term support policy reflected in class and attribute in terms of acculturation.

Crowd funding is the method of raising money for a project, companies from a large group of people via the Internet, in return for future products or equity. Kickstarter is the largest and most successful crowdfunding site where creative projects raise reward based funding. Drawing on dataset of 80,267 projects with combined funding over $1.3b from 8.1m people, this paper suggest that backer select project based on their preference on the project, instead profitability of the project. It suggests that well-established platform and big size of network increases the chance of success of the project due to a ripple effect and blockbuster effects. Clear communication about the project's idea and goal is highly correlated with success. Regular communication on the project site, such as by constant progress updates, helps the success of the project. Equity-based crowdfunding is emerging as an innovative means of raising capital for businesses, so it has been receiving a lot of attention and expectation from the government and the market. The findings of this paper and others will help to get some understanding and insight into equity-based crowdfunding. However, Kickstarter differs from equity-based crowdfunding in the goals of the backers. Kickstarter's backers are not investors, they are contributors. To understand equity-based crowdfunding, the subject will need further study.

Climate change has become the main cause of the exacerbation in natural disasters. Social Overhead Capital(SOC) structure needs to be checked for displacement and crack periodically to prevent damage and the collapse caused by natural disaster and ensure the safety. For efficient structure maintenance, the optical image technology is applied to the Structure Health Monitoring(SHM). However, optical image is sensitive to environmental factors. So it is necessary to verify its validity. In this paper, the accuracy of estimating the vertical displacement was verified with respect to environmental condition such as natural light, measurement distance, and the number of image sheets. The result of experiments showed that the effect of natural light on accuracy of estimating vertical displacement was the greatest of all. The measurement angle which was affected by the change in measurement distance was also important to check the vertical displacement. These findings will be taken into account by applying appropriate environmental condition to minimize errors when the bridge was measured by camera. It will also enable the application of optical images to the SHM.

The previous studies based on a resource-based view of firm highlighted the role of resources within a firm in creating and sustaining competitive advantage. Recent research, however, the relational view points to the importance of inter-firm sources(or relational capital) in creating firm competitiveness. In international business field, the studies on born-global firms also states that when firms are lack of ownership-specific advantages in their internationalization process, they resort to the external partners and social networks to complement their resource scarcity. By adopting the relational view and born-global firms concept, a network-based approach needs to be applied to explain the international strategy of Korean service firms. This is because most of Korean service firms own less ownership-specific advantages than global competitors. This study proposes Korean firms' global network building and exploiting strategy to enhance their international stages of development. The network, for example, Global Korean Tourism Network, enables network members access to the valuable resources and capabilities they are lack of when undergoing internationalization process. This study's contribution is along two dimension. First, even global Korean network is emerging as a major issue in recent years, we could not figure out how to build global Korean network for service firms. This studies gives an answer. Second, we derived what benefits can be gained from the network if Global Korean Tourism Network is developed for hotel, tourism, convention firms' internationalization.

Smartphone use has become a part of everyday life, not only for adolescents but also for elderly and older people. Thus, this study explored the effect of demographic variables, the amount of smartphone usage, type of smartphone use and psychosocial variables on smartphone dependence of the elder group. We analyzed the data of 5627 (50s and 60s) of the Internet overdependence survey data of the Korea Information Society Agency in 2016. As a result of hierarchical multiple regression analysis, More frequency of smartphone use of weekday and weekend, and usage time of smartphone of weekday were related to greater smartphone dependence. More smartphone use for information seeking and games were associated with greater smartphone dependence. And, as loneliness and anxiety increased, smartphone dependence increased, while smartphone dependence decreased, as social capital increased. Through this study, it is necessary to understand characteristics related to smartphone dependence of elder and older group, and to use this knowledge to solve their smartphone dependence. Future studies also need to identify the causal relationship between predictors of smartphone dependence in elderly and older people.

The form of company divides private and coporate companies. In general. private company has direct connection with owner's fortunes. On the contrary, cooperate company is established by a group of people who invest capital funds on their company and has an independent character. In the case of private company, their are many merits that owner can obtain all the benefits without divisions. However, the owner can mix up the control of accounting between public and private matters. As a result confusing, it is difficult to estimate financial situation of company and is limited to fund supply. Futhermore, owner has unlimited liabilities with law credit as a social cognition. Especially, the government tries to induce conversion of private company into cooperation one on the basis of benefits of tax and so on. In those situations, the purpose of this thesis is to study the management benefits with the conversion of private company into cooperate one focucing on the related tax reduction effect. To do this, I have reviewed all of the related textual achievements and tested the real significancy of tax reduction effect of conversion empirically. Finally, I have concluded that the conversion of private company into coporate one has many benefits including significant tax reduction effect. In other side, I have considered and reviewed many difficulties related conversion privated company into cooperate one and suggested some improvements as results. This thesis is comprises 5 chapters as follows; The first chapter explains purposes and methodologies and extents of this study. The second chapter deals the theoretical basis of conversion of private company into cooperate one and cooperates diverse benefits and types and processes of conversion. The preceding research achievements are also reviewed in this chapter. The third chapter deals empirical testing on the real tax reduction effect of the conversion. The analysis is proceeded through t-test of difference of tax between pre and after conversion. The result is presented so positively that I can conclude that cooperate conversion of private company has real benefit of tax reduction. The forth chapter deals the difficulties and improvements related with conversion. They are considered and reviewed at various aspects such as practical, financial and tax aspect. In fifth chapter, I summarise all of the significant points of this study and have conclusions in various aspects at last. In final point, this study is not enough in sample numbers and sample collecting area for empirical testing of significant tax reduction effect of cooperate conversion and research of more foreign achievements. Those are remained as continuing future studies.

As an impactive factor on industries and national economy, The Social Overhead Capital(SOC) is major factor to determine the national competitiveness and the investment of SOC is essential for its economic growth. Accordingly, introduction of the preliminary feasibility study and establishment of legal institutionalization and evaluation system has been carried out and reviewed since 1999. Nevertheless of these efforts, basic problems such as lack of scientific method for investment evaluation and loss of effectiveness on feasibility studies are continuously being brought up. Moreover, as the preliminary study to improve the mentioned problems is mainly focused on the economic and estimated demand analysis, the study of policy analysis, the most important phase during a feasibility study, is still insufficient. Therefore, in this paper, a quantitative decision-making model, to which the performance assessment method of Value Engineering(VE) is applied, is developed and proposed to improve the policy analysis of (preliminary) feasibility study that requires combining with relative studies, to induce quantitative analysis method, and to contribute the improvement of value on the political aspect for SOC investment goals and use as a strategic decision-making method by systematic analysis.

The purpose of this study is to find the effects of triple helix model on the firm innovation, especially focused on the moderating effects of trust in Daegu Gyeongbuk. There are two ways of triple helix interactions in Korea. One is a traditional triple helix interaction in which entrepreneurial universities have a central role. As the other way, such 3rd-sector type organizations as technoparks have a important role in facilitating the triple helix interactions. We collected data from 231 firms located in the Daegu-Gyeongbuk region. According to the findings, firstly, 3rd-sector type organizations such as technoparks have a positive(+) effect on the firm innovation. But a traditional triple helix interaction has not. Secondly, a 3rd-sector type support has much more positive(+) effects on the firm innovation than a traditional triple helix interaction. Thirdly, the trust has a positive(+) moderating effect on the firm innovation in the two-type of the triple helix interactions. In the conclusion, research implication, limitation of this study, and future directions are suggested.
