This paper criticized the recent Korean 'creative economy policies' focused on regional developmental implications. Even though the policies targeted to promote ICT new startups and build virtuous circle of ICT industrial ecosystem in Korea as a whole, the outside regions of the Seoul-Busan industrial axis where the bases of ICT industries are very weak would suffer from systematic exclusion in ICT investments and deepening regional disparities. Second, ICT-centered policies would selectively affect or operate commensurate with the size of regions in this low-growth, after-financial crisis age. Third, the possibilities of regional insularity and lock-in in these low levels of 'related variety' regions would worsen the industrial competitiveness. Lastly, the policies should be reoriented to fortify region-based creative economic ecosystem based upon triple helix learning region.

The purpose of this study is to start from the recognition of the problem of why the sanctions of the international community could not indicate a great effect. In order to find answers to this question, this study focuses on China's aid to North Korea and analyzes the determinants of support for North Korea. Despite a tough international community's sanctions against North Korea, China has taken a dual stance on sanctions and support for North Korea. As for this dual attitude of China, this study approaches the internal and external situation of the support to the North with the rationale for the Two-level game theory. China's sanction against North Korea could be divided into two categories: external factors and domestic factors. These factors include strengthening supremacy in China, checking the US, playing a responsible role in China, securing resources in North Korea, sustaining stable growth in China, maintaining the legitimacy of China's socialist political system, and spreading the Beijing consensus. Based on the analysis of these factors, it could be expected that China's aid for North Korea will be official, informal, or continuous, and it will be difficult for the North to stop supporting North Korea or deteriorating North Korea- China relations.

This study aims to elucidate the actual state of family care on the basis of the exact amount of time, and to verify its influencing factors and results. To this end, family caregiving was analyzed using the 2019 Korean Time Use Survey. The analysis results were as follows. First, the average time spent on adult family care was 115 minutes per day, a large proportion of family caregivers were women, the average age was relatively high, there were many unemployed, and household income was relatively low. Second, the analysis of influencing factors revealed that those who were women, older, married, and of a low household income had a considerable likelihood of becoming a family caregiver and had a longer caring time. Third, analysis of the relationship between family care and other activities showed that the family caregiving time was in a substitute relationship with paid work or leisure time, but it was in a complementary relationship with housework time, which was more evident in the case of high-intensity family caregiving. On the basis of these results, this study proposes the implementation of regular family care surveys, expansion of family care support policies, and modification of support for caring time according to the nature, goals, and attributes of caregivers.

The purposes of this study are, 1) to explore the factors related to the family caregivers' preferences for service utilization both of the community-based welfare and health-care services, and 2) to examine the reasons why not want to use services analyzing a survey data obtained from family caregivers(n=1,000). Anderson and Newman's Behavior model was employed to examine the factors related to the preferences for service utilization. The main results are as follows. 1) Logistic regression analyses demonstrated that predisposing factor(such as age and relations with frail elderly) and enabling factor(such as economic status, secondary caregiver, informal informational support provider, etc) were significant predictor for caregivers' preference for service utilization. Contrary to an expectation, needs factor was negatively related to the preference for service. More specifically, the more they have service needs, the less they show their willingness to use community-based service both in welfare and health-care services except for care education program. 2) Caregiver identified 'family caregiving consciousness'(family should take care of frail elderly, elderly dislike be taken care of) as an important reason not want to use community services next to financial factor. These findings have several implications for policy making especially for 'public long-term care insurance' which was planned to start in 2007.

Pickling of oxidized 304 stainless steel has been investigated using rotating disk electrode in waste acid solutions generated from the etching process of silicon wafer in order to recycle them. The waste acid solution contained acetic, nitric, hydrofluoric acids, and silicon of $19.6g/L^{-1}$. Electrochemical behavior during the pickling was distinctively different between the original and silicon-removed acid solutions. Open circuit potential was continuously changed in the original solution, while it was discontinuously changed and fluctuated in the silicon-removed solution. Fast and abrupt removal of surface oxide layer with severe pitting was observed in the silicon-removed solution. It was found that solution temperature had the most influential effect on glossiness. Surface glossiness after pickling was decreased with solution temperature. At the same condition, the glossiness was higher in the original solution than in the silicon-removed solution.

This study was carried out to investigate biological and antioxidative activities on the fruit of bogbunja (Rubus coreanus Miquel). Total contents of phenolic compounds contents in cultivars ripened fruit and immatured wild-type fruit were 222 and 190mg/g, respectively, Polysaccharide contents of immatured wild-type fruit were the highest value of 320U. For EDA analysis, immatured wild-type fruit showed over 95％ in 100$\mu\textrm{g}$/mL of sample concentration, which is the the most effective. Levels of SOD-like activities in immatured and cultivar ripened fruits were 81％ and 77%, respectively, For the inhibitory effect on lipid peroxidation, all of bogbunja prepared were similar with those of $\alpha$-tocopherol as control. The inhibition of ACE activities on the water extracts of bogbunja fruit showed over 98%, especially, in immature wild-type and cultivar bogbunja.

This article focused on the meaning of the 1979 Moon Treaty and its future. Although the Moon Treaty is one of the major 5 space related treaties, it was accepted by only 11 member states which are non-space powers, thus having the least enfluences on the field of space law. And this article analysed the relationship between the 1979 Moon Treay and 1967 Space Treaty which was the first principle treaty, and searched the meaning of the "Common Heritage of Mankind(hereinafter CHM)" stipulated in the Moon treaty in terms of international law. This article also dealt with the present and future problems arising from the Moon Treaty. As far as the 1967 Space Treaty is concerned the main standpoint is that outer space including the moon and the other celestial bodies is res extra commercium, areas not subject to national appropriation like high seas. It proclaims the principle non-appropriation concerning the celestial bodies in outer space. But the concept of CHM stipulated in the Moon Treaty created an entirely new category of territory in international law. This concept basically conveys the idea that the management, exploitation and distribution of natural resources of the area in question are matters to be decided by the international community and are not to be left to the initiative and discretion of individual states or their nationals. Similar provision is found in the 1982 Law of the Sea Convention that operates the International Sea-bed Authority created by the concept of CHM. According to the Moon Treaty international regime will be established as the exploitation of the natural resources of the celestial bodies other than the Earth is about to become feasible. Before the establishment of an international regime we could imagine moratorium upon the expoitation of the natural resources on the celestial bodies. But the drafting history of the Moon Treaty indicates that no moratorium on the exploitation of natural resources was intended prior to the setting up of the international regime. So each State Party could exploit the natural resources bearing in mind that those resouces are CHM. In this respect it would be better for Korea, now not a party to the Moon Treaty, to be a member state in the near future. According to the Moon Treaty the efforts of those countries which have contributed either directly or indirectly the exploitation of the moon shall be given special consideration. The Moon Treaty, which although is criticised by some space law experts represents a solid basis upon which further space exploration can continue, shows the expression of the common collective wisdom of all member States of the United Nations and responds the needs and possibilities of those that have already their technologies into outer space.

Due to the fact that it is relatively easy to transfer technology between application developers or content providers, low entry barrier in the business causes fierce competition among the venture companies in mobile service industry. Our study examines a sustainable strategies to operate a business for venture companies that are in a highly competitive technology-intensive industry. In this paper, we examine how venture firms created a network and brought synergy effects, using network theory. Korean venture firm, YelloMobile, uses unique strategies of merger and acquisition through the method of swapping equity and thereby establishing network. We contribute to expand network theory by examining three elements of network: such as network structure, network governance mechanisms, and network contents.

The study starts from the critical thought on why most of female-headed single-parent families are under poverty regardless of their hard working. The study is to explore the lives of low-income single-parent families as working poor and to develop comprehensive policies for them out of poverty and other social vulnerability, using the concept of social exclusion which has been broadly introduced in the field of social science. Specifically, the study aims to analyse the process of social exclusion of low-income single-parent households, by comparing the differential lives in the economic, social, political aspects among male-headed dual-parent household, female-headed single-parent household, and poor female-headed lone-parent household who is under the public poverty line. The study was based on the secondary data analysis. A total of 3182 samples(the first 2508, the second 235, and the third 439) were included. Using SAS 6.12, frequency, chi-square, means, and ANOVA were utilized for the statistical analysis. Results show that single mothers, on the whole, are vulnerable population in terms of employment, housing stability and income. Also, low-income households of single mothers are more negatively affected by the IMF economic crisis and carry more pessimism on their future. In comparison with male-headed households, single mothers have fewer support from social insurance as well as family resources and higher burdens of additional caring need for the old, the disabled, and the chronically ill. These findings identify the reality in which female-headed households with dependent children are exposed to the overall social vulnerability and thus are easily trapped into the social disadvantaged. finally, the study suggests the development of comprehensive policies and counter-measurements for low-income female-headed families to be the primary member in our society.

Soil erosion has caused serious environmental problems which threaten the foundation of natural resources. In this paper, we chose RUSLE erosion model, which could be connected easily with GSIS and available generally in mid-scale watershed among soil erosion models, and extracted factors entered model by using GSIS spatial analysis method. First, this study used GIS database as soil map, DEM, land cover map and rainfall data of typhoon Memi (2003) to analyze soil loss amount of Dam basin. To analyze the changes of soil loss in considering basin characteristics as up-, mid- and downstream, this study calculated soil erodibility factor (K), topographic factors (LS), and cover management factor (C). As a result of analysis, K and LS factors of upstream showed much higher than those of downstream because of the high ratio of forest. But C factor of downstream showed much higher than that of upstream because of the high ratio of agricultural area. As a result of analysis of soil loss, unit soil loss of upstream is 4.3 times than soil loss of downstream. Therefore, the establishment of countermeasures for upstream is more efficient to reduce soil loss.
