Purpose: To provide accurate information on induced labor and find strategies to enhance women's childbirth satisfaction. Methods: Participants were pregnant women expected to have normal vaginal delivery. A total of 113 women with induced labor and 61 women with spontaneous labor were surveyed. Data were collected using a questionnaire and electronic medical records. Results: The following variables related to labor progress showed significant differences between the induced labor group and the spontaneous labor group: length of the first stage of labor in primigravidas, use of analgesic, incidence of uterine hyperstimulation, incidence of fetal distress, and medical treatment for the expectant mother. Delivery type and the incidence of postpartum complications showed significant difference between the two groups. Induced labor women's childbirth satisfaction was mainly affected by the process of labor whereas spontaneous labor women's childbirth satisfaction was affected by the outcome of childbirth. Conclusion: Medical staff should have accurate information on the risk of induced labor and the benefits of a natural delivery. Moreover, medical staff should provide necessary information and environment for women to participate in the decision-making process.

Purpose: This study investigated the impact of key factors such as service quality, perceived benefit and brand familiarity on a consumer's intention to order online food delivery (OFD). In addition, mediating effect of electronic word of mouth (e-WOM) between relationships among selected key variables and OFD purchase intention is also assessed. Research design, data and methodology: This explanatory, quantitative study employed convenience sampling and collected data through online structured questionnaire from 304 respondents who are users of OFD apps based in greater Klang valley region of Malaysia. The data was then subjected to normality and reliability assessment followed by confirmatory factor analysis, validity assessment and structural equation modelling using IBM SPSS AMOS 24.0. Results: Findings revealed that service quality, perceived benefits and brand familiarity affects purchase intention positively and significantly. Perceived benefits demonstrated highest impact on purchase intention followed by brand familiarity and service quality. Findings also suggest that e-WOM fully mediates relationship between brand familiarity and purchase intention, however, the same was not observed for remaining two variables. Conclusions: The study has enriched OFD literature by investigating impact of selected key factors on purchase intention in the context of OFD. Implications, limitations and future research avenues are then discussed.

인터넷이 상거래를 변환시키면서, 지불 방법이 인터넷을 통한 상거래를 성공적으로 이끄는 데에 중요한 요소가 되고 있다. 전자 화폐는 기존 실물 화폐가 가지는 모든 특성들을 가지면서 모든 거래에 대해 보안성을 보장해 준다. 따라서 전자 화폐를 기반으로 하는 인터넷 지불 시스템이 향후 전자 상거래에 있어서 안전하고 효율적인 지불 방법으로 기대된다. 디지털 상품과 같은 컨텐츠 상품은 상품의 전달과 대금 지불이 동일 네트워크에서 이루어질 수 있다는 특성을 가진다. 이것은 전자 상거래 시스템의 설계를 최적화하는데 도움이 된다. 본 논문에서는 인터넷을 통한 디지털 상품을 거래하기 위해 특별히 설계된 전자 지불 프로토콜을 제안한다. 제안된 프로토콜은 가상 ID를 사용하여 익명성을 보장하고 지불 단계를 최소화시켰다.

최근 전자게시판은 각종 정보전달에 있어서 효과적인 도구로 사용되고 있다. 그러나 많은 전자게시판은 정보를 단방향으로 전달함으로 인해 상호작용성이 부족한 실정이다. 본 논문에서는 정보의 상호작용을 유지하면서 다양한 플랫폼에서 작동될 수 있는 안드로이드 기반의 전자게시판 소프트웨어 및 하드웨어에 대해 설계하고 구현한다. 특히 다양한 콘텐츠와 안드로이드 APP콘텐츠를 수정 없이 제시할 수 있는 콘텐츠 지원 프레임워크를 설계 하였다. 제안된 상호작용 DID는 관리자에게는 설치 및 관리를 용이하게, 사용자에게는 자연스럽게 정보를 수집하고, 활용할 수 있는 기능을 제공한다.

A small electronic nose (E-Nose) system has been developed using an 8-channel vapor detection array and personal digital assistant (PDA). The sensor array chip, integrated on a single microheater-embedded polyimide substrate, was made of carbon black-polymer composites with different kinds of polymers and plasticizers. We have successfully classified various volatile organic compounds such as methanol, ethanol, i-propanol, benzene, toluene, n-hexane, n-heptane, and c-hexane with the aid of the sensor array chip, and have evaluated the resolution factors among them, quantitatively. To achieve a PDA-based E-Nose system, we have also elaborated small sensor-interrogating circuits, simple vapor delivery components, and data acquisition and processing programs. As preliminary results show, the miniaturized E-Nose system has demonstrated the identification of essential oils extracted from mint, lavender, and eucalyptus plants.

World Wide Web(Web) supports bi-directional communication between corporations and consumers. In the year of Electronic Commerce, close relationships with consumers are more emphasized for corporations. Nowadays, corporations compete with corporations which are located in whole world through the media called Internet. In this competitive environment, to attract consumers' attentions, it is required to develope corporations' Web sites in the way to stimulate consumers' purchase intentions. To verify the elements needed to stimulate consumers' purchase intentions factors which influence consumers' purchase intentions were analyzed. Adaptation, shopping convenience and assurance-reliability were found to be positive factors for consumers' purchase intentions. It was also found that consumers' purchase intentions in electronic commerce market are influenced by previous shopping experiences. Consumers who have previous shopping experiences are mainly influenced by good delivery systems and shopping environments while who have no experiences are influenced by consumers' risks such as performance risk and personal and privacy risk when they intend to purchase products or services.

Urban regeneration is a large-scale program that must address challenges such as a significant number of involved projects, diverse participants and their conflicting objectives, and a long life span. In an effort to address these issues, the Interactive Electronic Technical Manual (IETM) is applied to urban regeneration in order to provide a guideline to enhance urban regeneration program management. Through a survey, three major functionalities required in the IETM are identified: process map provision, customized information delivery, and communication ability with other information systems. To achieve these functionalities, the development framework of the IETM and the associated technologies are examined.Its characteristics can be sum up ontology-driven metadata, user-oriented process map composition system and so on. Finally, the usage scenarios of the IETM are discussed.

In this paper, a pre-layout design approach for high-speed microprocessor is proposed. For multilayer PCB stark up configuration as well as selection and placement of decoupling capacitors, an effective solution for reducing SSN and EMI is obtained by modeling and simulation of complete power distribution system. The system model includes VRM, decoupling capacitors, multiple power and ground planes for core voltage, vias, as well as microprocessor. Finally, the simulation results are verified by measurements data.
