중국교회의 선교운동이 조용히 그러나 강력하게 진행되고 있다. 정부의 종교 탄압정책으로 인해 그 실체가 외부에 잘 알려지지 않았다. 그러나, 중국 교회는 장기간 선교사를 파송하고 글로벌 선교운동에 참여해 왔다. 중국 교회의 급속한 성장, 중국의 경제 성장, 일대일로 정책이 중국 선교운동 발전에 배경이 되었다. 중국 선교 운동은 교회의 미성숙성, 정부의 종교 제한 정책, 선교 경험의 부재 등으로 많은 어려움과 혼란 (난상)을 겪고 있다. Tabor Laughlin은 25명의 중국 선교사의 현지 적응 과정을 7가지 영역으로 연구한다. 연구를 통해 그는 중국 선교 운동의 독특한 12가지 경향성과 6가지 해결 과제 (Implication)를 발견한다. 중국선교운동의 건강한 발전을 위해서 6가지 해결과제가 해결되어야 한다. 한국 교회 선교운동은 중국과 같이 비서구권 선교운동이면서, 중국보다 한 세대 앞선 선교경험을 가진다. 한국교회의 선교경험에 비추어 6가지 과제에 대한 해결점을 제안하고자 한다.

Research on service innovation suggests that involving customers in the development of new services is a major contributing factor to the success of new services (e.g. Carbonell et al., 2009; 2012; Melton & Hartline, 2010; 2015; Zhihong et al., 2015). The purpose of this study is to provide an overview of the literature on customer involvement (CI) in new service development (NSD) both offline and online and to identify the major current issues faced by researchers and future research challenges. This paper approaches CI from the perspective of “co-creation for others” (Witell et al., 2011), that is participating in developing services that can benefit other customers. A search was done on three major databases, EBSCO; Emerald, and ScienceDirect, using various keywords (CI; NSD; service innovation; user involvement; co-creation, and customer participation) from 2002 (first CI paper published (Carlborg et al., 2014) to 2016. Relevant studies start with mainly qualitative inquiries whereas in the last 5 years there are more surveys and new types of qualitative research such as netnography and action research. The most important questions addressed are who is involved and how. Various studies investigate the role of different types of customers such as close; lead; ordinary or guided; their characteristics such as proactiveness; knowledge or experience; motives; emotions, or dissatisfaction, and their capabilities such as knowledge absorptive capability or relational capability. Furthermore, the way customers may be involved is analysed from many perspectives including the stages of involvement; the modes and intensity of involvement in each NSD stage (e.g. Melton and Hartline, 2010; Paasi, 2014) as well as the characteristics of effective CI. Moreover, studies in the online environment look at the web based tools for CI such as social media or virtual communities (Ryzhkova, 2012); the nature of customer contributions on social networks (Sigala, 2012); the role of lead users in developing online services (Schuhmacher & Kuester, 2012; Mahr & Lievens, 2012) and the drivers of customer participation in virtual brand communities (Zhilong et al., 2015). Major current issues include which customer or firm actions should be included in each stage and why; what is the role of relationships in effective CI; how we can select customers for NSD and what is the role of virtual environments in CI. Future research challenges include developing guides for customer selection for NSD; analyzing the nature of CI (modes; intensity; types of contributions; customer roles and actions in each stage; communication types and skills); using virtual environments for CI and determining the link of various relationship concepts with CI.

The purpose of this study is to develop a multi-dimensional scale measuring consumers’ perceived challenge in shopping fashion products online, and to verify its validity and reliability. Relevant literature is first reviewed to identify possible dimensions of perceived challenge. Next, Study 1 is conducted in order to explore the dimensions empirically and to see whether the dimensions that emerged were consistent with prior findings. A total of 190 responses to an open-ended question was qualitatively analyzed by using content analysis. The findings of Study 1 generate 26 items reflecting four dimensions (i.e., product knowledge, previous experience, website functionality, and product availability), which correspond to the dimensions suggested in literature review. Study 2 is subsequently conducted to refine the items so that the perceived challenge scale establishes cross-validation, convergent validity, discriminant validity, reliability, and predictive validity. A total of 238 responses is quantitatively analyzed by using exploratory factor analysis, confirmatory factor analysis, and structural equation modeling. In the results of Study 2, the perceived challenge scale is found to consist of a total of 16 items reflecting three dimensions: E-commerce Challenge (corresponding to Previous Experience reported in Study 1), Retailer Challenge (corresponding to Website Functionality), and Product Challenge (corresponding to Product Knowledge); all Product Availability items have been eliminated through the item refinement process. Specifically, E-commerce Challenge and Retailer Challenge are found to predict flow, supporting flow theory, while Product Challenge fails to lead to flow significantly. Implications, limitations, and suggestions for future studies are also discussed.

In this knowledge based society, the debate on ICT has permanently shifted from ʻwhyʼ ICT for development, to ʻhowʼ comprehensive and holistic ICT policies can unleash human potential and enhance peopleʼs capabilities to improve their lives. Recognizing this untapped potential and development strategies incorporating ICT are being increasingly promoted and launched across the developing countries. While the potential advantages of ICT for development are enormous in developed countries, national policies of developing countries are yet to adequately reflect truly comprehensive and integrated strategies for harnessing and exploiting this potential. This paper presents an analysis of National ICT policy of Bangladesh. Through the examination of ICT policy, in particular in the field of agriculture and rural development and analysis of applied policies and strategies implemented in these area, this paper identifies challenges and opportunities which provides lessons for policy-makers and practitioners involved in the field. This analysis reveals that the policy is inadequate to impact positively on the agriculture and rural development of Bangladesh. The policy places little emphasis on the integration and infusion of ICT in the countryʼs agriculture and rural development. Policy implications and suggestions are offered to ensure maximum use of ICT potentials in the countryʼs agriculture and rural development.

In the process of China’s modernization of social and economic development, China has gradually expanded the scope of foreign trade, especially the deepening of economic and trade cooperation with South Korea, and the steady growth of bilateral trade and investment. However, during this period, it will be affected by internal and external factors, leading to the increasing trade deficit between China and South Korea. The frequent occurrence of trade friction has caused a serious impact on the economic and trade development of China and South Korea. Therefore, in the actual work, it is necessary to respond flexibly to the challenges, meet the opportunities and adopt scientific countermeasures according to the development status of Sino-South Korea economic and trade cooperation, so as to promote the continuous progress of the two countries’ economic and trade.

RCEP, through its unique rules of origin accumulation, promotes mutual tariff concessions between Korea and China, reduces trade production costs, and will further promote the negotiation of the Korea-China FTA. Focusing on the post-epidemic era, South Korea and China should strengthen the consensus on economic and trade cooperation and use the higher standard and more comprehensive RCEP agreement to achieve a mutually beneficial and win-win situation. The industrial supply chain between South Korea and South Korea is the result of the spontaneous formation of the market, mutual benefit and win-win results. Third-party markets such as the Far East can better cooperate to provide impetus for the economic development of the two countries and the recovery of the world economy.

This study aims to determine the technical aspects of organic food systems in rice agribusiness and analyze the pattern of economic and institutional structures of agribusiness in East Java of Indonesia. Also, this study investigates the feasibility of farming and understands the strategies of rice agribusiness development. This study was conducted in several places in East Java of Indonesia, covering the district of Blitar, Kediri, Bondowoso, Tulungagung, and Malang. The data were collected through a structured questionnaire and focus group discussion. Furthermore, the data were analyzed using efficiency analysis, revenues analysis, and SWOT analysis. The findings indicated that, technically, the district of Bondowoso, Malang, Kediri, and Tulungagung had implemented the organic systems, while the district of Blitar applied under semi-organic systems. The pattern of economic institutions of agribusiness commodity consists of the production facility, farming, post-harvest and product processing, marketing, and support services institutional. These results showed that the organic rice farming is economically viable, and the government support was provided in the form of the establishment of development centers, the facilitation of agricultural machines, integrated crop management field school, and the organic certification. These findings suggest that several places in East Java have prospective opportunities for production of rice agribusiness development.
