The purpose of this study is to investigate the "map of mind" or subjectivity regarding consumption behaviors of consumers in the digital environment. This study investigated the values and psychological and behavioral characteristics that motivate consumption for each types of consumers in digital environment. 76 Statements were selected from literature review and popular press articles that introduced consumption related phenomena. A total of 33 participants included experts on digital consumption and lay person, The results indicated that there are 6 groups representing Korean consumption patterns in digital environment: Digital Modernist, Digital Boomer, Digital Chic, Digital Ludens, Digital Conservative, and Digital Renaissance. This research is meaningful in that it provides a framework to view the diverse consumption behaviors in a more holistic rather than independent perspective, considering psychological aspects such as personal values and lifestyles.

Knowledge ecosystem means a dynamic knowledge circulation, including knowledge creation, exchange and sharing and utilization. It is also the field of knowledge practice, which creates interactions in knowledge exchange between people and groups. The key premises of knowledge ecosystem, based on the nature of general ecosystems, can be characterized as follows: first, it primarily focuses on social networks between people and organizations participating in the process of knowledge circulation; secondly, knowledge ecosystem thrives on diversity of knowledge; and thirdly, it is significant for selection of valuable knowledge and adoption of appropriate knowledge. This review attempts to make a systematic examination of a wide range of existing studies on knowledge ecosystem. In so doing, it is expected to provide a basis for further inquiry into more critical and complicated issues. Although the scarcity of existing research-at least those in Korea-may limit the implications of findings, this review offers a set of suggestions for future research.

In most of the existing real-time schedulers producing the total value as large as possible, the service times for all schedulable tasks are computed at each time a new task arrives. If all scheduled tasks would be executed completely before a new task arrives, the schedule may produce the greatest total value. But this is not always true in real situations. In many cases, (a) new tasks arrive(s) before all the scheduled tasks are executed completely. In this paper, we propose a unique scheduling algorithm for real-time tasks. The proposed algorithm determines the service times only for some tasks with earlier deadlines while the existing algorithms determine the service times for all tasks. This partial computation decreases the average scheduling complexity ramatically, even though, in the worst case, the complexity of the proposed algorithm becomes O(N2), which is equal to that of a previous algorithm that has been known as a less complicated one.

A test on the significance of style factors which were revealed to be significant in U.S. and U.K. literature is conducted in this study using appraisal-based returns of offices in Korea. Region, size (appraisal value), value-growth propensity (yield gain gap) and leasing conditions (the number of tenants, the length of average leased period and the proportion of key tenant) are included in the analysis model as style factors. The empirical result suggests that firstly core region and large size are significant but they increase risk as well as return contrary to general belief, secondly value propensity significantly decreases risk as well as return as it does in U.S. and U.K., finally the number of tenants among leasing conditions decreases risk as well as return but the length of average leased period and the proportion of key tenant are not significant.

The purpose of this study is to identify the differences between consumers and suppliers about the necessity and effectiveness of hand-tied bouquet packaging in a retail shop and consumer needs of floristry packaging for sustainable condition were surveyed and analyzed using questionnaire format. In the introduction, the understanding and sustainability of floristry design were considered. The questionnaire consisted of general purchasing type, packaging related items, and consumer and supplier profile. Consumers were middle class residents living on Mokdong apartment complex, a small number of consumers who aren't living on Mokdong and workers and suppliers were florists currently active nationwide. This study suggests an effective and strategic packaging direction that reflects consumer needs, focusing on the similarity and difference of their needs and it presents them as business models. The results of the future research are expected to be the basis for producing and distributing packaging design.

우리나라는 "제 3차 신재생에너지 기술개발 및 이용 보급 기본계획"을 통해 2030년까지 111.5조 원을 투자하여 전체 에너지의 11%를 신재생에너지로 공급한다는 목표를 설정하였다. 그러나 신재생에너지는 기존의 원자력이나 화석에너지에 비하여 생산비용이 높아 보조나 융자 등의 정부지원에 의존하여 보급이 이루어져왔다. 신재생에너지 보급확대 및 산업발전을 위한 보급정책의 일환으로 정부는 2012년부터 RPS(Renewable Portfolio Standard, 신재생에너지 공급의 무화제도)를 도입키로 확정하였다. RPS의 도입은 일정규모 신재생에너지 시장수요를 창출함과 동시에 신재생에너지원간 가격경쟁 구도 형성의 유인이 될 수 있다. 이는 전력가격 일괄상승 및 녹색가격제도(Green Pricing) 등의 정책적 논의로 이어질 수 있다. 따라서 소비자 측면에서 신재생에너지 전력의 가치를 어떻게 평가하는지를 분석하여 RPS 시행제반의 정책적 논의의 기초자료를 마련할 필요가 있다. 특히 RPS는 신재생에너지원 간의 경쟁을 가능하게 하므로 개별 신재생에너지원에 따라 소비자 선호의 차이가 어떻게 나타나는지 연구되어야 한다. 이에 본 연구는 환경재 혹은 비시장재화의 가치추정에 가장 널리 활용되고 있는 조건부가치평가법(Contingent Valuation Method; CVM)을 적용하여 풍력, 태양광, 수력으로 생산한 전력에 대한 소비자의 지불의사액(Willingness to Pay; WTP)을 분석하는 모형을 수립하였다. 이를 위해 Zografakis et al.(2010), Yoo and Kwak(2009), 이창훈 황석준(2009), Nomura and Akai(2004), Bately et al.(2001) 등의 선행연구를 참조하여 신재생에너지 전력 가치의 설문에서 고려되어야 하는 요인들을 선정하였다. 이를 토대로 설문 시나리오를 작성하여 각 요인들이 신재생에너지 전력에 대한 지불의사액 결정에 어떠한 영향을 미치는지 분석가능한 모형을 설정하였다. 뿐만 아니라 기존 연구들이 신재생에너지로 생산된 일반적인 전력에 대한 지불의사액을 질문하는데 그쳤다면, 본 연구에서는 각 원별로 지불의사액의 차이를 도출할 수 있는 설문모형을 구축하는데 중점을 두었다. 본 연구결과는 향후 설문수행을 통하여 신재생에너지원별로 소비자의 선호를 분석할 수 있는 연구로 발전될 수 있으며, 이는 RPS 도입으로 인한 전력가격 정책 수립의 기초 연구자료로 활용될 수 있다 하겠다.

The purpose of this study was to explore the levels of ethical consumptions and related variables on ethics of adolescents as consumers. This subjects were 552 middle and high school students. The research results are summarized as follows. 1. The scores to measure ethical consumptions level of the adolescents was ranged from 2.87 to 3.08, which were relatively low. 2. The ethical consumptions(fair-trade product consumption, donation and giving, local consumption and eco-friendly consumption) in demographic variables were found to have significant differences depending on their religion, perceived social class, father's education and mother's education. 3. The result of hierarchical regression analysis indicated that consumer education experience, the eco-friendly values, materialism, saving, experiencing mass media on affecting the fair-trade product consumption. The major variables affecting the ethical consumptions in the donation and giving were materialism, consumer education experience, experiencing mass media and the eco-friendly values. The significant variables affecting the local consumption were the eco-friendly values, consumer education experience, materialism, experiencing mass media and saving. The major variables affecting the eco-friendly consumption were the eco-friendly values materialism.

For a social venture in early stage, it is very difficult to set up a strategy as it has to pursue two contradictory goals; economic value and social value. The platform strategy can be good alternative solution for social ventures as it seeks building-up connections with other businesses to co-create value despite of limited resources. A Korean social venture, JUMP! which adopted platform strategy in the early stage, and successfully applied 4 key factors of platform strategy; core competency, value creation ability, efficiency and network effect, has been able to develop sustainable growth for itself and induce innovation and growth among the participants within the platform. This study was intended to research effect of adoption and successful application of platform strategy for social ventures in the early stage of start-up and draw conclusion through case study that platform strategy works for sustainable growth of social ventures.

The purport of this essay is to examine the possible compatibility of liberalism and perfectionism. Liberalism is typically considered as anti-perfectionism. So communitarian critique of liberalism focused on the effects of its anti-perfectionism. But liberalism could be interpreted as compatible with perfectionism. Joseph Raz attempts to develop and defend "perfectionist" liberalism. He rejects anti-perfectionist "neutrality" and claims that the goal of political action is to encourage pursuit of what is truly good and discourage pursuit of what is morally unworthy. Despite this strong perfectionist claim, Raz's political philosophy gives pride of place to individual liberty, or autonomy, which he considers to be intrinsically valuable. One exercises autonomy in choosing among a plurality of human goods. Nonetheless, Raz forthrightly denies the value of autonomy used to choose what is morally bad and says that society has no reason to protect worthless, much less morally evil, options. Raz is more conventionally liberal, however, in espousing a version of J. S. Mill's "harm principle", arguing that a due regard for autonomy rules out government use of coercive means to discourage "victimless" immoralities. However, there are some serious questions about whether Raz's strong perfectionism can support his principled rejection of "morals legislation". I think that if his strong perfectionism could be a little "weakened" and his autonomy could be interpreted as having only formal value rather than having intrinsic value, then his perfectionism could be compatible with liberalism.
