소셜네트워크게임(SNG)은 말 그대로 사회적인 연결망이나 관계에 기반한 게임이다. 사람들과의 관계가 게임에 있어서 중요한 요소가 되어 이를 잘 활용해야 원활한 진행을 할 수 있다는 점이다. 소셜네트워크 서비스에 바탕을 둔 소셜네트워크 게임의 활동은 실제 기업상품과 연결시켜 구매를 유도할 수도 있고 또 소셜네트워크 게임 상의 가게를 기업의 웹사이트나 쇼핑몰과 연결하여 게임 속에서 광고를 통한 마케팅도 가능하다. 본 연구에서는 개발게임을 사례를 들어 소셜커머스에 기반한 새로운 SNG 비즈니스 모델을 제안하고 차후 SNG 수익모델 연계방식을 제시하였다.

Objective: Social genetic effects (SGE) are an important genetic component for growth, group productivity, and welfare in pigs. The present study was conducted to evaluate i) the feasibility of the single-step genomic best linear unbiased prediction (ssGBLUP) approach with the inclusion of SGE in the model in pigs, and ii) the changes in the contribution of heritable SGE to the phenotypic variance with different scaling ${\omega}$ constants for genomic relationships. Methods: The dataset included performance tested growth rate records (average daily gain) from 13,166 and 21,762 pigs Landrace (LR) and Yorkshire (YS), respectively. A total of 1,041 (LR) and 964 (YS) pigs were genotyped using the Illumina PorcineSNP60 v2 BeadChip panel. With the BLUPF90 software package, genetic parameters were estimated using a modified animal model for competitive traits. Giving a fixed weight to pedigree relationships (${\tau}:1$), several weights (${\omega}_{xx}$, 0.1 to 1.0; with a 0.1 interval) were scaled with the genomic relationship for best model fit with Akaike information criterion (AIC). Results: The genetic variances and total heritability estimates ($T^2$) were mostly higher with ssGBLUP than in the pedigree-based analysis. The model AIC value increased with any level of ${\omega}$ other than 0.6 and 0.5 in LR and YS, respectively, indicating the worse fit of those models. The theoretical accuracies of direct and social breeding value were increased by decreasing ${\omega}$ in both breeds, indicating the better accuracy of ${\omega}_{0.1}$ models. Therefore, the optimal values of ${\omega}$ to minimize AIC and to increase theoretical accuracy were 0.6 in LR and 0.5 in YS. Conclusion: In conclusion, single-step ssGBLUP model fitting SGE showed significant improvement in accuracy compared with the pedigree-based analysis method; therefore, it could be implemented in a pig population for genomic selection based on SGE, especially in South Korean populations, with appropriate further adjustment of tuning parameters for relationship matrices.

Despite repeated exhortation about the importance of social and human dimensions of systems development, socio-organizational issues continue to be neglected and ignored in the current information systems practice. A review of the human information processing literature suggests that the reasons for this continuing lack of attention to social issues may be found in the limitations of human cognition and information processing capacities. Bostrom and Heinen(1978) and Kumar and Bjorn-Anderson(1990) also suggest that the inadequate attention to social problems and issues by the analyst could originate from the analysts limited problem perception. This research explores how the representation forms of information systems(IS) methodology used in understanding and modeling the problem situation affect such systems development problem perception. Typically, a system development methodology prescribes the use of system models(i.e., system representations) to understand, analyze, evaluate, and design the information system. Given the size and complexity of information systems, and the abstraction and simplification underlying the modeling process, system representations usually depict only a limited set of aspects of the system. Thus, a methodology whose representations are limited to technical aspects will tend to limit the analyst's perspective to a technical one only(Kumar & Welke, 1990). Following the same line of argument, in contrast, it is the conjecture of this study that a methodology which specifies both social and technical aspects of IS development will help the analyst develop a more comprehensive view of the IS problem domain. Based on the above concept, a theoretical model was first developed which explained the systems analysts cognitive process. Drawing on this model, a research model was developed hypothesizing the impacts of representation forms on problem identification. The model was tested using a laboratory experiment with 70 individual subjects. A special computer software was developed with a hypermedia authoring tool to conduct the experiments in order to avoid experimenter biases and to maintain consistency in administrating repeated experiments. The program, designed to replace the experimenter, consisted of functions such as presenting the subjects with problem material, asking the subjects questions, and saving the typed answers of the subjects. The results indicate that representation forms strongly influence problem identification. It was found that the use of the socio-technical representation form led to the findings of more social problems than the use of technical representation form. The results imply significant effects of representation forms on problem findings and also suggest that the use of adequate representation forms may help overcome dysfunctional effects of our limited information processing capacity.

In the last two decades, the welfare states have undergone the changes of restructuring towards two ways. One is a restructuring of workfare and the other is a restructuring of the gender model of welfare state. In Korea, the workfare is reflecting on the DJ Welfarism 'Productive Welfare', but the gender model has a little effect on the public policies. By the way, It is imported that has the gender perspective in approaching the self-supporting program in the public assistance representing of the DJ Welfarism. Because almost 60% of the beneficiaries of the program are women. The Gender-mainstreaming strategy criticizes for the laws, the public policies, the public programs that considered gender-neutral or gender-blinded, and then complete the equality between women and men through the modification or development of those. The approach of Gender-mainstreaming is very important strategy for not only women who are self-reliance recipient but also successful settlement of self-supporting program. Nowadays that program is not execute yet. Then we hardly have information about recipients and the results that expected from that. At this point of gender-mainstreaming, this report suggest the strategy to development and settlement of the self-supporting program in the basics of analysis for the low-income unemployed and the government policy response to unemployment. For the gender models of the self-supporting program, the most important thing is throwing the male breadwinner model and adoption the dural-earner model (the gender model) about that program. Then we must produce gender-statistics data, develop programs for public work, job replacement, job training, evaluating system, etc. with gender perspective.

Recent development of information technologies produces a lot of community services. Social Network Service is one of the community services on the world wide webs. In the Social Network Service, a user can register other users as friends and enjoy communication through a virtual message. Previous researches show a few social service methods using manually generated tagging. However, the manual social tagging is not widely used in many social network services. Moreover, they do not consider ubiquitous computing environment. We propose a recommendation method for social service using contexts in ubiquitous environment. Our method scores documents based on context tags and social network services. Our social scoring model is computed by both a tagging score of a document and a tagging score of a document that was tagged by a user's friends.

The environmental problems aren't only restricted in single area or country, but also related in all around the world. Various approaches have been tried to protect and utilize properly the environment. Especially, building area has been attempted to provide the model which could explain the degree of environmental influence and technology development criteria to lessen the environmental impact in building life cycle. The environmental impact in the building life cycle can be overally explained with sustainability. Sustainability can be utilized to establish the target level of building to environmental influence. This paper aimed at extracting items to evaluate the building sustainability, divided into social, economic and environmental aspects. First, 93-items is extracted from 3 areas through existing literature review. Second, the 93-items would be controlled and reviewed into 21 items, which are five social aspect items, two economic aspect items and twelve environmental items, because 93 items can not properly be applied and evaluated. And, it provided the model to combine the extracted items of each area. In social aspect, the outdoor noise is more affect than any other items. In environmental aspect, the item of surface-to-volume is more affect than any other items.

Global construction and engineering consulting (E&C) firms are actively seeking entry into overseas markets based on loan projects from multilateral development banks to provide a basis for entry into overseas markets and sustainable growth. Bids on these projects are competitive between global top firms in terms of the technical level and price due to the limited number of projects; thus, developing a successful partnership to complement competence has become an essential element to win bids. In this regard, many studies have analyzed enterprises through characteristic analyses or the derivation of influential factors from the past social networks based on social network analysis (SNA). However, few studies have been conducted to reflect the process of changes to analyze collaborative relationships. Thus, this study aims to identify dynamic changes in past social networks and develop a model that can predict changes in the relationships between E&C firms based on similarities or differences between firms, presenting a methodology to target firms for appropriate collaboration. The analysis results demonstrate that the sensitivity of the developed prediction model was 70.26%, which could accurately predict 163 out of 232 actual cooperative cases.
