본 연구는 1980년 이후 후기산업사회의 경제 사회구조의 변화로 인해 새로운 사회적 위험이 등장하면서 이에 대한 복지국가의 정책적 전환을 실증적으로 분석하고 있다. 새로운 사회적 위험구조로서 세계화, 탈산업화, 인구고령화, 여성의 고용률, 그리고 아동인구의 비중이 소득보장지출과 사회투자지출로 구성된 사회지출구조를 변화시켰는지를 분석하였다. 이를 위해 1997-2007년까지 OECD 회원국을 대상으로 패널데이터를 구축하고 패널교정표준오차를 고려한 로지스틱 회귀분석을 사용하였다. 그 결과, 무역개방도, 여성의 사회진출, 아동인구의 비중이 사회투자 확대를 중심으로 한 사회지출 구조변화에 영향을 미치고 있는 것으로 나타났다. 즉, 무역개방도가 높을수록, 아동인구비율이 감소할수록, 그리고 여성 고용률이 증가할수록 소득보장지출보다는 사회투자지출 증가가 더 큰 것으로 분석되었다. 탈산업화와 인구고령화는 사회지출 구조변화에 유의미한 영향을 미치지 않는 것으로 나타났다. 이러한 결과는 새로운 사회적 위험구조에 대해 선진복지국가의 복지체계가 소득이전 중심의 정책에서 고용을 통한 생산적 사회정책으로의 완전한 전환을 의미하지는 않지만, 전체적인 방향 전환은 어느 정도 이루어지고 있음을 나타낸다고 할 수 있다.

The purpose of this article is to analyse the expenditure structure of the welfare mix; in order to grasp the holistic feature of the Korean social welfare. Most of all, the article attempts to elaborate the estimation methods of social welfare expenditure by including the components from which has been excluded so far - indirect tax expenditure of the government, nursery payments of households, life insurance pay-outs for survivors, inter-household private income transfers and the value of caring work of the family. In so doing, the article estimates that the total social welfare expenditure including state, enterprise, market, NPOs and family reached at 24.7% of GDP in 2000, which is approximately 2.5 times more than public social welfare expenditure. It implies that non-state, private sectors dominates the structure of social welfare provisions in Korea. In addition, based on the analyses of the expenditure structure, the article defines the main feature of Korea's welfare mix as the 'mixed structure of the welfare mix dominated by the protective family', or 'expanded public sector, relatively limited market, and protective family'. Such a family-dominated welfare mix structure in Korea indicates that the fundamental source of solidarity of the Korean social welfare system is family and, therefore, the welfare regime of Korea can be classified as 'Conservative'.

Purpose - The existing marketing studies using Social Network Analysis have assumed that network structure variables are time-invariant. However, a node's network position can fluctuate considerably over time and the node's network structure can be changed dynamically. Hence, if such a dynamic structural network characteristics are not specified for virtual goods purchase model, estimated parameters can be biased. In this paper, by comparing a time-invariant network structure specification model(base model) and time-varying network specification model(proposed model), the authors intend to prove whether the proposed model is superior to the base model. In addition, the authors also intend to investigate whether coefficients of network structure variables are random over time. Research design, data, and methodology - The data of this study are obtained from a Korean social network provider. The authors construct a monthly panel data by calculating the raw data. To fit the panel data, the authors derive random effects panel tobit model and multi-level mixed effects model. Results - First, the proposed model is better than that of the base model in terms of performance. Second, except for constraint, multi-level mixed effects models with random coefficient of every network structure variable(in-degree, out-degree, in-closeness centrality, out-closeness centrality, clustering coefficient) perform better than not random coefficient specification model. Conclusion - The size and importance of virtual goods market has been dramatically increasing. Notwithstanding such a strategic importance of virtual goods, there is little research on social influential factors which impact the intention of virtual good purchase. Even studies which investigated social influence factors have assumed that social network structure variables are time-invariant. However, the authors show that network structure variables are time-variant and coefficients of network structure variables are random over time. Thus, virtual goods purchase model with dynamic network structure variables performs better than that with static network structure model. Hence, if marketing practitioners intend to use social influences to sell virtual goods in social media, they had better consider time-varying social influences of network members. In addition, this study can be also differentiated from other related researches using survey data in that this study deals with actual field data.

Many studies have pointed out that trust is the most important component of social capital. Although there have been lots of attempts to measure level of trust between members of community, it is hard to find studies which examine trust from the standpoint of structural aspects. Because of the recent rapid growth of SNS and openness trend on members and their friendship information, it became possible to understand the structure of trust relationships among users in SNS. This study aims to facilitate interpersonal trust by comparing the structure of the trust network among social network users. For this purpose, it proposes a method to explore the structure of trust network and strategies to evolve toward more open structure. In experiments to distinguish structure of trust network with three social network communities, it is discovered that ADVOGATO has characteristics of open and collective network together whereas EPINION and FILMTRUST have collective and open characteristics respectively.

Many real networks exhibit overlapping community structures. Recent studies have been performed that analyze the impact of overlapping community structure on information propagation, but few of them concerned with individual behaviors. From this point of view, we propose a Markov process model to evaluate the performance of information propagation in social networks with overlapping community structures. In addition, many individual social behaviors are combined in the model. For example, individuals may exhibit selfish behaviors, such as individual and social selfishness, and people may discard the information after they have used it. The accuracy of the model is verified by simulation. Furthermore, the numerical results show that both overlapping community structure of the network and individual behaviors have a significant impact on the outbreak size and propagation speed of the information. Additionally, the overlapping community structure of the social network can reduce the impact of selfishness on information propagation.

The objective of this paper is to derive a optimum distance and time taxi fare structure based on social costs. Social costs expressed in terms of congestion and vehicle operating costs were successfully internalized. Speed and volume data for three major arterials in Seoul CBD were used. Optimum congestion charge turned out to be 97.01 Won/Km which can be regarded as congestion tax in the context of Seoul CBD. This congestion tax can possibly be incorporated into time-based taxi fare structure. Congestion is likely to be reduced as a result of imposition of time-based taxi fare which reflects social costs.

In this study, the transition characteristics of purple series color names appearing in the clothing of the Joseon Dynasty were examined, and the associational meaning of each name were investigated through various methods. The results are as follows; First, Such characteristics as continuity, differentiation, substitution could be observed through the investigation of color names of purple-series appeared on the clothing in the Joseon Dynasty period. Secondly, the associational meaning could be subdivided into; social position symbolic meanings, usage meanings, economic meanings, and thought meanings. The social position symbolic meanings could be observed mainly in the single names which has been used since the ancient times, usage meanings could be observed in a wide variety according to the individual color names. The economic meanings could be observed by comparing the value of colored cloths and colored threads. The thought meanings were mainly related with the Confucianism. Thirdly, the associational semantic structure were established on the basis of associational meanings of purple-series color names. Individual color name on the social position symbolic semantic structure symbolizes [government official] and [servant]. Through usage semantic structure individual color names could be understood structurally according to the social position, sex distinction, wearing situation, items of clothing, and structure of clothing. Individual names on the economic semantic structure were segmented by the semantic components of the values in [high], [medium], [low] prices, kinds and quantity of dyes. The thought semantic structure could be subdivided [Confucianism] and [The Thought of Taeil] in its semantic structure.

The purpose of this study is to examine Korea's social conflict structure from System Dynamics perspective and to suggest policy direction for conflict resolution. Unlike previous studies on Korea's social conflict, this study tries to find out core structure of Korea's social conflict with help of studies on system archetypes. As a result, Korea's social conflict structure was analyzed as a combined prototype of 'limit to the growth' archetype and 'success to the successful' archetype. Based on this combined system archetype, a simple conflict model was simulated to examine the magnitude of conflict and success that could be reached under different conditions. With simulation results, policy suggestions were made for conflict resolution.

The purpose of this study was to introduce the concept of social capital to the studies of human ecology in Korea. Social capital theory provides a framework for analyzing well being of families because the concept of social capital can be understood as an important family resource, including social networks, social supports, and family structure. The utilization of the social capital theory, considering both positive and negative effects on equality, in the studies of human ecology is expected to contribute to the social understanding of the characteristics of households as a system that are related with environments, and provide a basic theoretical framework for discussing family structure, human capital development, poverty, and healthy families.

본 논문에서는 복지국가 변화를 분석하기 위한 연구방법을 제시하고자 하였다. 분석의 차원을 급여 구조 자체의 근본적인 변화를 의미하는 '재구조화'와 구조 내부 요소들의 내용을 수정하는 '구조내부의 변화'로 나누었다. '폐지', '대체'/'이전'그리고 '도입'이라는 변화의 결정적 계기를 통과한 개혁을 '재구조화'로서 간주하여, 재구조화 이후 사회보장 담당기구에 법으로 부여된 '관할의무'가 어떻게 변화하는지 살펴보았다. 이러한 평가척도에 따라 재구조화의 결과를 공공중심의 재구조화, 민간중심의 재구조화 그리고 현상유지로서 평가하였다. '구조 내부의 변화'에 대한 연구를 위해선 사회급여의 포괄범위, 수급조건, 급여수준과 지급기간, 재정방식 그리고 전달체계를 시기별로 맞비교하는 방법을 사용하였다. 본 논문에서는 복지국가가 지닌 여러 제도 중 가장 비중이 있는 사회보장제도를 중심으로 이러한 분석방법을 적용해 보았다. 구체적 분석대상은 영국, 스웨덴, 독일의 노령보장제도, 질병보장제도 그리고 실업보장제도였다.
