Purpose The purpose of this study is to investigate which decision factors continue to use the service based on the online simple payment service. In this study, we will examine how to activate the service from the continuing factors through the dual-model theory consisting of personal dedication and constraint dedication which are frequently used in relation marketing. Design/methodology/approach In this study, we investigated the activation of online simple settlement service using factors affecting the preference of the simple payment service based on the dual-model of dedication-based mechanism and constraint-based mechanism. Findings This study confirmed that customer satisfaction and convenience under the dedication -based mechanism were found to be linked to the preference of the simple payment service. Switching cost under the constraint - based mechanism showed that the customer had no binding ability to continue using the service of the current provider. Likewise, preference was found to have a direct effect on the actual frequency of use of the simple payment service, the number of uses compared to the total number of online payments, and willingness to use more.

NFTs, which guarantee ownership of digital files using blockchain technology, are the new field for the content industry. The NFT provided new opportunities for content creators to trade digital contents without going through mediation freely. Additionally, collectors and investors can safely and easily own their works without the threat of illegal copies. However, since only a limited number of content creators are participating in the NFT market, there needs to be an influx of various content creators and a process of popularization for this market to grow and develop into the main stage. Furthermore, research on NFT has been limited, and understanding the drivers of creators choosing to participate in NFT is insufficient. Thus, this study aims to identify the factors affecting content creators participating in NFT by applying a mixed-methods approach and presenting practical implications. Using topic modeling and in-depth interviews, this study derives the positive and negative factors and suggests strategies to activate content creators' participation in the NFT market. Through this, we can guide that management implication to reduce the risks and costs of participating in NFTs is needed to encourage the participation of creators. It will also provide insight into ways to develop the NFT content market.

Recently, the start-up firms have been under the spotlight because they can create many jobs and are regarded as the growth engine of a country in the fourth industrial revolution. Moreover, after the global financial debacle, many countries emphasize on an entrepreneurial spirit and venture firms. they also pay attention to the importance of educations to promote the start-up firms. In this work, based on technology acceptance model, we try to identify the main factors of accepting online start-up education system. We first defined this system as the online start-up education system which refers to a system to support learning for knowledge, experiences and overall process of start-up firms' tasks. This system also simulates tasks related with prep-entrepreneur so that can be regarded as a kind of decision support systems. As this system has some characteristics, we confirmed some factors of extended technology acceptance model. In our experiments, we find that the perceived ease of use and trust are main factors of acceptance for the online start-up education systems. These results mean that the system should be made to be easy and trustful for their users. Therefore, we expect that this work will be helpful to researchers and developers who consider start-up education systems and provide a way to activate founding start-up firms.

Various government-based consulting techniques are being adapted to increase competitive power and to achieve management innovation of Korean farms. These business consulting services are offered by free or paid consulting. This study focuses on what socio-economic characteristics are affecting farmers' intension of adapting consulting services, based on 169 surveyed data from Chunchungnam-do. Logit Model is used to identify the relationship between the probability of consulting intent and factors representing farm characteristics. The model was applied on each of free and paid consulting. According to the results, degree of consulting recognition, age, education, raised crop are significant factors affecting farmers' intension of adapting consulting service in the case of free consulting at 10% of significance level. In the case of paid consulting, level of farming, age, income, insufficiency of farming, and education were identified as significant factors. In terms of elasticity of each variable, most variables for free consulting service are inelastic to consulting intent, whereas age, level of farming, and education are elastic for paid consulting service. Overall results implies that more public relations are required to activate free consulting services for the farms with moderate level of farming. In the case of paid consulting, it is effective to adapt consulting services for younger farms with higher level of farming and education.

본 연구는 바이오 분야 연구데이터플랫폼인 K-BDS를 대상으로, 연구데이터 메타데이터의 품질이 연구데이터플랫폼의 활성화에 미치는 영향 및 이 관계에서 연구데이터플랫폼 이용에 관한 동기부여 요인의 매개효과를 밝히고자 하였다. 먼저 세 변인 간 구조적 관계를 구조방정식모형, 부트스트랩을 통해 분석하였으며 분석 결과, 연구자가 메타데이터의 품질에 대해 중요하다고 생각할수록 연구데이터플랫폼 이용의 동기부여 정도, 그리고 플랫폼의 활성화 의도가 높아지는 것으로 나타났다. 또한 동기부여 요인의 매개효과도 확인되었다. 추가적으로 각 변인의 하위요인간의 세부적인 구조를 회귀분석과 Sobel test를 통해 파악하였다. 그 결과 바이오 분야의 연구데이터 공유의 활성화를 위해서는 검색가능성을, 연구데이터 재이용의 활성화를 위해서는 발견가능성을 높이는 것이 가장 효과적이며, 인용가능성은 플랫폼의 활성화에 영향을 미치지 않는 것으로 나타났다. 따라서 플랫폼을 활성화하기 위해서는 우선적으로 메타데이터 품질을 향상시킴으로써 시스템적인 지원을 충분히 하는 것이 중요하며, 이를 통해 플랫폼에 대한 신뢰를 높이고 인용에 대한 혜택을 제도적으로 정착시켜 갈 필요가 있다는 시사점을 얻을 수 있다.

This study comparatively analyzes the cases of CDMA (Code Division Multiple Access) and WIPI (Wireless Internet Platform for Interoperability) to find out the success and failure factors of technology policies in the field of mobile communication industry. For this purpose, the two cases are analyzed through a new analysis framework, which is made by combining System of Innovation with a range of variables derived from precedent studies, such as external environment, institutions, technological system, governance structure, and interactions of actors. The results of analysis show that in the CDMA case, the following factors led to success ; Korea made good use of the external opportunities in the early stage of digital communication technology and adopted a suitable governance structure for the technological system. Main actors in Innovation System had strong will for success and engaged in cooperative interaction. For the WIPI, however, the timing of technology policy was inappropriate and a unsuitable governance structure for technological system was chosen because of path dependence. The Innovation System failded to respond efficiently to the situation where conflicts among actors had intensified, US trade pressure had increased and innovative smartphones emerged. The results of this study provide the practical implications for the success of technology policy; namely it is important to choose a governance structure that suits the external environment and characteristics of technology and to activate cooperative interactions among actors in Innovation System.

CD4+ T helper (Th) cells play a crucial role in the modulation of innate and adaptive immune responses through the differentiation of Th precursor cells into several subsets, including Th1, Th2, Th17, and regulatory T (Treg) cells. Effector Th and Treg cells are distinguished by the production of signature cytokines and are important for eliminating intracellular and extracellular pathogens and maintaining immune homeostasis. Stimulation of naive Th cells by T cell receptor and specific cytokines activates master transcription factors and induces lineage specification during the differentiation of Th cells. The master transcription factors directly activate the transcription of signature cytokine genes and also undergo post-translational modifications to fine-tune cytokine production and maintain immune balance through cross-regulation with each other. This review highlights the post-translational modifications of master transcription factors that control the differentiation of effector Th and Treg cells and provides additional insights on the immune regulation mediated by protein argininemodifying enzymes in effector Th cells.
