The purpose of this study was to examine the self-regulation in E-commerce business and review the major issues of self-regulation in several countries. This paper reviewed the legislation for the self regulation of APEC, OECD and EC, and introduced the regulation system for several countries, such as U.S. U.K and Japan. Also, we analyzed the current issues and problems of self-regulation in Korea and tried to suggest the future direction. There were three different regulations such as market forces, government regulation and self-regulation and the model of self-regulations were shaped in various types. Even though the government made the standard regulations for business sector but it was impossible to direct individual firms and their compliance of those regulations. To compensate the government regulation, the self regulation with low cost is needed and also two kinds of regulations has to be unified to enhance the regulation system in E-commerce. Industries should participate for the regulation voluntarily and consumers must give an award of legislation for self-regulation to motivate the self-regulations of industries.

The reason why modern companies adopt cutting-edge technologies aggressively is mainly due to maintain the competitiveness in this cut-throat business environment. One of the most important technology factors to maintain the competitiveness in this modern e-business era is how to adopt and apply information technology(IT). More and more companies are trying to implement their management strategies by applying IT, and therefore it is now important to understand IT strategy. Many of leading-edge companies believe that they need a structured and systematic approach, called ISP (Information Strategy Planning), to secure competitive IT capability, and heavily invest their resources to achieve the excellence in IT. However, eventual effects from those investments are not always proportional since every investment has its own investment parameters and objectives. In this research, we tried to develop a systematic model to verify the relation between the business competitiveness and ISP. First, in order to include the factor 'ISP', we modified the models suggested by past research results, and then analyzed the influences from IT investments and quality of ISP on the IT excellence of businesses. To prove the validity of the developed model, several sets of surveys were performed for 66 companies in various industries including electronics, manufacturing, finance, and service. The result of the research has shown that the quality of ISP impacts more on a corporate's business competitiveness, but none on business output.

Economic deprivation of households remains a significant economic issue in the world. Researchers have shown great concern in identifying crucial factors to enhance poor households' socio-economic performance. Therefore, this paper aims to develop a new conceptual framework to investigate the influence of different microfinance services on households' socioeconomic performance using moderated mediation analysis of various crucial factors. Focus-group interviews with managements of the microfinance institution, i.e. Amanah Ikhtiar Malaysia (AIM), and a systematic literature review were conducted for this purpose, and a new framework for the future study has been developed. The result from focus-group interviews and systematic literature review propose microfinance financial services, training programs, and business coaching as independent factors, whereas household socioeconomic performance as a dependent factor in the proposed model. Specifically, this study provides the direction to scholars to empirically test the direct relationship between financial services and household socioeconomic performance and the indirect relationship between training programs, business coaching, and household socioeconomic performance. Further, microfinance institutions' service efficiency is also included as a moderator that can strengthen microfinance services' effectiveness. The study also provides useful implications for policymakers, financial institutions, households, micro-enterprises, and researchers to better understand microfinance interventions and household economic mechanisms.

시멘틱 검색은 검색 사용자의 인지적 노력을 최소화하면서 사용자 질의의 문맥을 이해하여 의미에 맞는 문서를 정확히 찾아주는 기술이다. 아직 시멘틱 검색 기술은 온톨로지 또는 시멘틱 메타데이터 구축의 난제를 갖고 있으며 상용화 사례도 매우 미흡한 실정이다. 본 논문은 기존 시멘틱 검색 엔진의 한계를 극복하기 위하여 이전 연구에서 고안한 위키피디아 기반의 시멘틱 텐서공간모델을 활용하여 새로운 시멘틱 검색 기법을 제안한다. 제안하는 시멘틱 기법은 문서 집합에 출현하는 '단어'가 텐서공간모델에서 '문서-개념'의 2차 텐서(행렬), '개념'은 '문서-단어'의 2차 텐서로 표현된다는 성질을 이용하여 시멘틱 검색을 위해 요구되는 온톨로지 구축의 필요성을 없앤다. 그럼에도 불구하고, OHSUMED, SCOPUS 데이터셋을 이용한 성능평가를 통해 제안 기법이 벡터공간모델에서의 기존 검색 기법보다 우수함을 보인다.

Although existing studies on e-health have usually focused on e-health services adoption intention, there is a dearth of studies on the barriers that affect e-health services retention intention especially in India. Additionally, although studies have mostly focused on utilizing expectation-confirmation model to understand innovation related barriers, innovation resistance theory (IRT) has been overlooked. As Indian e-health service providers face stiff challenges due to customer's unwillingness to continue using the service, there is a need to bridge the research gap that exists in this context. This mixed-method study, based on responses received from 289 participants and 1154 online negative reviews from e-Health providers in India, examines the barriers from the IRT stance. Results of this study reveal a notable negative association between tradition, value and financial barrier and intention to continue using e-health services. Additionally, continuance intention affects recommendation. The study concludes with various implications and scope for future research.

This study proposes a mathematical model to estimate the economic value of weather forecast service, among which the precipitation forecast service is focused. The value is calculated in terms of users' satisfaction or dissatisfaction resulted from the users' decisions made by using the precipitation probabilistic forecasts and thresholds. The satisfaction values can be quantified by the traditional value score model, which shows the scaled utility values relative to the perfect forecast information. This paper extends the value score concept to a collective value score model which is defined as a weighted sum of users' satisfaction based on threshold distribution in a group of the users. The proposed collective value score model is applied to the picnic scenario by using four hypothetical sets of probabilistic forecasts, i.e., under-confident, over-confident, under-forecast and over-forecast. The application results show that under-confident type of forecasts outperforms the others as a measure of the maximum collective value regardless of users' dissatisfaction patterns caused by two types of forecast errors, e.g., miss and false alarm.

3-컬럼의 트리플 테이블로 구성되는 트리플 데이터베이스의 질의 처리는 고비용이 드는데, 단축 경로는 그 비용을 감소시키는 방법으로 알려졌다. 어떠한 단축 경로를 선택 구성할지는 주요한 문제이며, 질의 빈도를 기반으로 단축 경로 이득을 계산하는 방식이 주로 사용된다. 하지만 이러한 방식은 트리플 데이터의 추가 혹은 변경을 적절히 반영하지 못한다. 본 논문에서는 질의 처리 시간 단축 측면뿐 아니라 경로 구축 및 유지 비용도 고려하는 이득 모델을 다룬다. 이득 모델은 이득 함수로 설계되어 단축 경로 선택 기법에 적용된다. 이득 함수 구성 인자가 미치는 영향을 실세계 트리플 데이터를 사용해 실험 분석한다.

With the e-business paradigm emerging, the website became a critical resource for most corporations. However, the amount of value creation through internet is still in question. This paper shows the result of an exploratory study on website assessment, following the tradition of Technology Acceptance Model (TAM). We viewed the intended usage as the value of the website and added such factors as playfulness, commitment, system quality, and information security as external variables of the model. Website types, visiting purposes, and the user system quality were included as moderators. The website value could differ depending on website types, purposes of the use and system quality. In the case of internet shopping malls, playfulness, compatibility, website quality were identified as key influencers, while for stock trading users, however, commitment and security factors are more important. In terms of user purposes, information search requires both the compatibility and the website quality. Also the website quality was strongly affected by the user system quality. In other words, any investment of upgrading the website system quality can be meaningless unless the user system quality is improved as well. For each variable considered, empirical results are discussed and practical implications are provided.

Mosts of export/import cargo has been moving using maritime transport means. Korea had been driven the system automation project using EDI document since the mid-1990s. However, this automation system comes upon about 40-50% against overall maritime business process, manual or paper document processing work is existing as ever. International e-business environment also has changing into electronic form document transaction from paper document-based transaction. International standardization organization, UN/CEFACT proposed UNeDocs for paperless jtransaction. UNeDocs is a specification to define XML data model as well as electronic form. With UNeDocs, it is not necessary to generate the duplexed data, and it can support user convenient and guarantee the flexibility. This paper defines the UNeDocs data model for EDI and Off-Line processing at the current maritime business. Then, it have to check XML syntax and structure for the defined data model through quality of document check system. Also, it explains the applying plan about the defined UNeDocs data model. It is possible to support paperless transaction as defining UNeDocs-based standard data model and converting into paper document, XML and EDI document using UNeDocs data model.
