The rise of crowdsourcing and web 2.0 opens plenty of opportunities for companies who want to exploit external sources of ideas for internal innovation. Utilization of crowdsourcing for product design and development has been attracting the attention of both enterprises and researchers. Many cases of implementation of crowdsourcing for product design and development such as: Threadless, FIAT Mio, Lego online Factory, etc., have made crowdsourcing a promising alternative source of innovative power. Although crowdsourcing gained access due to improved Internet access and web 2.0, it is little understood how the crowd, with respect to participation, behaves for any crowdsourcing project. To investigate this, we conducted an experiment on a real crowd of engineering related individuals to figure out the crowd participation pattern for various product design and development phases of a new product development project. The experiment results give a quantitative view of the participation of the crowd (i.e., crowd participation pattern) in various phases of a product design and development process that utilizes crowdsourcing, provide a practical guidance for companies to harness the power of the crowd sensibly, and provide experimental data for further research in this field.

Purpose By participating in the business ecosystems, customers make both positive and negative impacts in the ecosystem. In particular, users of platform businesses participate in the business ecosystem as partial employees who voluntarily create and manage content. According to the organizational behavior literature, employees' psychological ownership toward the organization has an influence on the organizational competitiveness. Thus, with an assumption that customers gain psychological ownership toward the business that they participate in, it is important to analyze the process and the factors that influence their psychological ownership. This study proposes a research model that describes the process: customers undertake customer socialization, which then lead them to participate in the business-level and the business ecosystem-level activities. Through the participation, customers gain psychological ownership toward the business. Design/methodology/approach Based on a structural equation model, this study analyzes the data regarding the factors in the research model. Data was collected by surveying college students who represent themselves as Facebook and DaumKakao users. By analyzing the collected data, the relationships are validated between customer socialization and customer participations (i.e., both business-level and business ecosystem-level participation), and between the participations and customers' psychological ownership. Findings Based on the validation, this study confirms the importance of managing customers' psychological ownership and offers customers' participation by their socialization as a solution for increasing customers' psychological ownership. Also, this study proposes the business ecosystem research model as the general research framework for future research and expands the scope of strategic management from the individual level strategy to the business ecosystem wide perspective.

The study examined the relationship between six broad personality traits(i.e., HEXACO; Honesty-humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness to experience), safety job performance, and traffic accidents of Korean occupational bus drivers. Based on the job performance model, we included safety participation as well as safety compliance as safety job performance. Analyses on the data from a total of 492 bus drivers showed that all HEXACO personality traits except Honesty-humility, were valid predictors for both safety compliance and safety participation. Honesty-humility was only related to safety compliance. Among the six personality traits, high conscientiousness and low emotionality were best predictors of safety job performance. As for traffic accidents, conscientiousness was a sole significant predictor. Furthermore, the mediation analysis showed that the effect of conscientiousness on traffic accidents was completely explained by safety compliance and safety participation. The implications of the current findings for practice and future research as well as the limitations of the current study were discussed.

The expression of the endogenous human apolipoprotein(apo)E gene was significantly induced when HepG2 cells were treated with exogenous 25-hydroxy-cholesterol. This sterol-mediated apoE gene upregulation appears to require the participation of a positive element for the apoE gene transcription (PET) ( -169/ -140), a core sequence of upstream regulatory element (URE)1 enhancer of the human apoE gene. This PET was renamed as sterol regulatory element (SRE)4 based on its new role as a sensor for the level of intracellular sterol. Furthermore, a gel mobility shift analysis showed that binding activity of the SRE4 binding protein (BP) obtained from HepG2 cells was induced by sterol treatment, while that from either MCF7 or BT20 cells remained unchanged. Binding activity of SRE4BP was also induced in mouse macrophage cells, J774A.1, by sterol treatment, but it was drastically reduced when cells were subjected to treatment of AY-9944, a potent inhibitor for sterol synthesis. However, binding activity of Spl, which is a co-binding protein to the SRE4 region, remained the same in either condition, suggesting that SRE4BP (formally known as PETBP) may be mainly responsible for the sterol-mediated regulation of the apoE gene expression. Deletion analysis of the core binding site of SRE4BP by gel mobility shift assays showed that the minimal sequence of the SRE4BP binding appears to reside between -157 and -140, confirming the identity of SRE4 with the previously determined core sequence of URE1.

Purpose Live streaming commerce refers to the fact that people receive live audio and live video directly over the net. While some e-retailers use Live Streaming as a marketing strategy, the impact of live streaming commerce on customers' reuse intentions is unknown. The purpose of this study is to discuss the impact of live streaming commerce by external environmental factors based on S-O-R theory. Design/methodology/approach In this study, we developed a research model based on the S-O-R theory. Using the questionnaire survey method, consumers who used live streaming commerce on Taobao.com were taken as research subjects. Our research model aims to find out how content attributes, real-time interactions, media characteristics, and situational characteristics as stimulus factors influence consumers' perceptions and thus reuse intentions. Findings The results of the analysis show that external environmental factors have a significant impact on consumer perceptions and that perceived risks and flows can influence consumers' reuse intentions. In addition, we also examined the impact of reuse intentions on consumers' active participation. These results show that live streaming commerce can influence consumer perceptions and behavior in several ways.

The convenience and flexibility due to the spread of Internet allowed consumers to easily participate in marketing activity. Consumers want to participate in designing, manufacturing, delivering of products and service by expressing their opinions to the companies because they want to buy customized goods where their requirements are incorporated. We can expect that, through this interactive process of customization between consumers and companies, strong relationship quality may be built as a result of the interaction. The main purpose of this study is to examine the influence of consumer perception of customization on relationship quality in the e-business context. To accomplish this purpose, I reviewed the concept of customization, identified the perceptive factors of customization in e-business context (i.e., perception of participation level, assessment of flexibility), and examined the type of customization. Whether customization type generates varying degrees of perception of customization and relationship quality is revealed. As a result, collaborative product/service customization generated the highest relationship quality. Assembled product customization that was built based only on predicted consumer needs without any interaction between consumer and company showed a low level of relationship quality. And this type had no significant difference from standardized products. In short, there is a strong need for e-business companies to interact with consumers to improve relationship quality.

The proportion of software in the automotive industry is steadily increasing due to the rapid technological development of automobile E/E parts. Because the automotive E/E technology is now on the basis of intelligent automobile and advanced safety automobile technology. The purpose of this study is to investigate the effect of organizational capability (organizational resource capability and management capability), process capability (process capability, customer Requirement management capability), performance dimension (motivation, participation level). In this study, we conducted questionnaires and statistical analysis on engineers (members of the Korea Advanced Automotive Technology Association) who perform research and development activities in the R&D organization of the automotive E/E part in South Korea. ANOVA is applied for the verification of the difference in performance measured by organizational capability, process maturity, and motivation participation level according to company characteristics (level of processing : supply chain configuration, annual sales, total SW development ratio). According to the results of this study, in order to improve the performance of ASPICE or ISO 26262-related consulting project, a different consulting approach strategy considering the characteristics of organization and personnel is needed. In summary, the analysis results for the three main treatment levels are as follows. The difference in organizational capacity, process capability and performance was found to be statistically significant according to supply chain configuration and annual sales, but it was found that the difference of response according to the proportion of total SW was not significant.

본 연구는 최근 새로운 고객 참여방식으로 자리매김한 고객 투표를 통한 마케팅 의사결정 방식에 주목하였다. 이는 서비스 산업에서도 중요한 고객 임파워먼트 전략(Customer Empowerment Strategy, CES)의 하나인 선택형 임파워먼트 형태라고 할 수 있다. 선택형 임파워먼트 중 투표방식의 장단점에 국한되어 있는 선행연구와는 달리 본 연구에서는 다수의 최종안이 선정되는 상황을 상정하고, 고객이 하나의 후보에 투표하는 단수투표 시스템과 복수의 후보에 투표하는 다중투표 시스템 간의 차이를 고객의 지속적 투표 참여 의사와 투표 참여 행태를 통해 분석하였다. 또한, 이러한 투표 시스템 간의 차이를 만드는 요인을 투표 결과의 불확실성으로 보고 그 매개효과를 검증하였다. 연구 가설의 검증을 위해 사람과 상품을 대상으로 투표를 하는 두 개의 실험을 진행하였으며, 다중선형회귀분석과 매개효과 분석을 실시하였다. 그 결과, 상품 투표의 경우 다중투표 시스템은 고객 참여 의사와 전략적 투표 행태를 증가시키는 것으로 나타났으나, 사람에 대한 투표의 경우 전략적 투표 행태에만 유의한 영향을 미치는 것으로 나타났다. 또한, 불확실성은 다중투표 시스템의 효과를 매개하지 않아 간접효과는 없는 것으로 나타났다. 본 연구는 학술적으로 선택형 임파워먼트를 세분화시킴으로써 향후 연구에서 고객 참여 방식을 구체화 했다는 점과 실무적으로 기업의 투표 시스템 선택에 방향성을 제시한다는 측면에서 기여점이 있다.
