  • Mobile commerce provides a convenient shopping experience in which users can buy products without the constraints of time and space. Mobile commerce has already set off a mega trend in Korea. The market size is estimated at approximately 15 trillion won (KRW) for 2015, thus far. In the Korean market, social commerce and open market are key components. Social commerce has an overwhelming open market in terms of the number of users in the Korean mobile commerce market. From the point of view of the industry, quick market entry, and content curation are considered to be the major success factors, reflecting the rapid growth of social commerce in the market. However, academics' empirical research and analysis to prove the success rate of social commerce is still insufficient. Henceforward, it is to be expected that social commerce and the open market in the Korean mobile commerce will compete intensively. So it is important to conduct an empirical analysis to prove the differences in user experience between social commerce and open market. This paper is an exploratory study that shows a comparative analysis of social commerce and the open market regarding user experience, which is based on the mobile users' reviews. Firstly, this study includes a collection of approximately 10,000 user reviews of social commerce and open market listed Google play. A collection of mobile user reviews were classified into topics, such as perceived usefulness and perceived ease of use through LDA topic modeling. Then, a sentimental analysis and co-occurrence analysis on the topics of perceived usefulness and perceived ease of use was conducted. The study's results demonstrated that social commerce users have a more positive experience in terms of service usefulness and convenience versus open market in the mobile commerce market. Social commerce has provided positive user experiences to mobile users in terms of service areas, like 'delivery,' 'coupon,' and 'discount,' while open market has been faced with user complaints in terms of technical problems and inconveniences like 'login error,' 'view details,' and 'stoppage.' This result has shown that social commerce has a good performance in terms of user service experience, since the aggressive marketing campaign conducted and there have been investments in building logistics infrastructure. However, the open market still has mobile optimization problems, since the open market in mobile commerce still has not resolved user complaints and inconveniences from technical problems. This study presents an exploratory research method used to analyze user experience by utilizing an empirical approach to user reviews. In contrast to previous studies, which conducted surveys to analyze user experience, this study was conducted by using empirical analysis that incorporates user reviews for reflecting users' vivid and actual experiences. Specifically, by using an LDA topic model and TAM this study presents its methodology, which shows an analysis of user reviews that are effective due to the method of dividing user reviews into service areas and technical areas from a new perspective. The methodology of this study has not only proven the differences in user experience between social commerce and open market, but also has provided a deep understanding of user experience in Korean mobile commerce. In addition, the results of this study have important implications on social commerce and open market by proving that user insights can be utilized in establishing competitive and groundbreaking strategies in the market. The limitations and research direction for follow-up studies are as follows. In a follow-up study, it will be required to design a more elaborate technique of the text analysis. This study could not clearly refine the user reviews, even though the ones online have inherent typos and mistakes. This study has proven that the user reviews are an invaluable source to analyze user experience. The methodology of this study can be expected to further expand comparative research of services using user reviews. Even at this moment, users around the world are posting their reviews about service experiences after using the mobile game, commerce, and messenger applications.

  • Sampling In this study, we examined the problems and their improvement plans associated with the reliability management sector in quality management engineer test conducted in Korea. First of all, there seems to be a problem in that the terminology is not unified and some techniques essential for reliability analysis are not included. We also looked at quality and reliability tests performed in foreign countries (especially USA) that Koreans often acquire. In particular, it can be seen that the CRE test almost overlaps with the contents of the reliability management engineer test in Korea. However, while the USA is an open book test, Korea is not, so the problem is that there are too many formulas to memorize on the part of the test takers. In addition, the analysis of the data is done manually without using computer software. If the test were an open book test like the CRE test in USA, it will be a test that can go beyond fragmentary knowledge and check whether test takers have the essential elements in reliability management. Lastly, if we adopt re-certification system through education and work within a certain period of time, as in USA, it will be a qualification test suitable for modern people living in a flood of information.

  • This paper aims to investigate changes in Korean family structures by reflecting on the perception of traditional family rites and family systems. In-depth interviews were conducted with 17 married middle-aged men (9) and women (8) who had at least one child. Findings were as follows: First, both married middle aged men and women internalized Confucianism. They thought that the head of household, who was male as far as possible, was needed for the formation of a normal family. In addition, both of married middle-aged men and women recognized married women as outsiders based on Chul-ga-we-in-sa-sang. And they put parents-children relationships ahead of couple relationships and supported Jang-ja-woo-dae-sang-sok (privileging the eldest son over the other children in terms of the distribution of family resources and inheritance based on Confucianism). However, there were some differences to support the use of Hang-ryul-ja, which is based on expressing the character of generation by sharing the first name, and the importance of Jok-bo. which is based on traditional family genealogical records. Second, even though women internalized Confucianism, they did not attach traditional meanings to memorial services for ancestors to the extent that men did and defined family members as a procreation family boundaries unlike men, who defined family boundary as original family members and procreation family members. In conclusion, even though family laws and culture have evolved from the patrilineal family system to one which promotes gender equality, married men and women internalize Confucianism. Instead, some transformations are evident from the perspective of females in terms of memorial services for ancestors and family boundaries.

  • With increased social participation of married women and with the notion of importance of pre-school childhood on human development, the importance of nurseries is being emphasized. The transformation of the traditional family system into a nuclear family system and the deterioration of the traditional child education have also put nurseries as a primal social interest. But, at present, at the end of 1994, only 10% of the children have benefitted from such facilities, the supply not being able to meet demand. Also, the spatial organization and the management of such facilities has been unsatisfactory. In this perspective, this study aims to grasp the present condition of nurseries, to investigate and analyse case studies, to suggest standards and reform measures, and based on these, to produce basic information for the formation of an architectural spatial model. We've selected investigation of present conditions and case studies, interviews, and observation as investigative methods and through these we've assessed tangible spatial planning and spatial proportion by parts. 1. The most preferred grouping method is toddler/preschooler type, and the group size and staff-to-child ratios vary according to the children's age 2. The younger children's activity rooms are located in the lower level, and the activity room of the children on the similar development stages are located adjacent to one another 3. Most of the facilities do not have the public spaces(indoor playrooms, dinning rooms, napping rooms, bathrooms, sickrooms) For dinning and napping, activity rooms are being used, and for sickrooms, director's room or staff rooms 4. As for the correlations of the spaces(home bases, activity rooms and its outdoor spaces, day-care-centers and its community), closed plan type is 90% over, and modified open plan is 10% min.

  • This study analyses the current status of trade in Korean fisheries and competitive power in export to China in the era of actual open-door policy, aiming to figure out problems in distribution Structure of fisheries and suggest directions for further development in this area. Political efforts have been consistently made to change distribution system of our fisheries into low-cost and high-efficiency system, but continuous contradictions occur in actual distribution. In this reality, we need a new perspective to reorganize distribution markets according to real conditions. To improve distribution Structures for fisheries, political focus should be given on reorganization of the entire structure. And to develop political directions for fisheries, we should evaluate its competitive powers and based on the results, we should develop efficient measures to use limited political resources.

  • As the limitations of the passive recognition domain, which is not guaranteed transparency of the operation process, AI technology has a vulnerability that depends on the data. Human error is inherent because raw data for artificial intelligence learning must be processed and inspected manually to secure data quality for the advancement of AI learning. In this study, we examine the necessity of learning data management before machine learning by analyzing inaccurate cases of AI learning data and cyber security attack method through the approach from cyber security perspective. In order to verify the learning data integrity, this paper presents the direction of data-preserving artificial intelligence system, a blockchain-based learning data environment model. The proposed method is expected to prevent the threats such as cyber attack and data corruption in providing and using data in the open network for data processing and raw data collection.

  • This study was conducted to investigate the effects of implementation of the healthcare accreditation system on patient safety, quality of medical care, organization culture and management performance of convalescent hospitals. Ten hospitals were selected at random from among 36 convalescent hospitals in Daegu that had obtained accreditation until September 2015. To accomplish this, hospital staff were surveyed from 15 February to 25 March, 2016 using a questionnaire with 253 objects. We investigated how the healthcare accreditation system has influenced patient safety, service quality, organization culture and performance of hospital management. The change in the treatment support system showed the highest score of 3.93 among quality change and medical service items, while that of personnel source culture showed the highest score of 3.78 points among organization culture items, and that of internal process view, study and growth view showed the highest score of 3.71 among management performance items. Multiple regression analysis revealed that factors positively changing hospital management performance were nurses, employees and managers, basic value systems, organization culture, personnel source culture, open system culture, hierarchical culture, and production oriented culture. The quality of patient safety and medical care was positively influenced by changes in the quality of convalescent hospitals after implementation of the healthcare accreditation system. However, among the four types of organizational culture, the financial perspective was relatively low compared to other perspectives.

  • Emphasizing the importance of R&D as a source of open innovation, Korean government is developing various programs focused on technology commercialization and is expanding investment on it. In spite of those efforts, technology commercialization is not vitalized yet due to the lack of demand for technology transfer, R&D planning scheme without considering market, immaturity of technology market, and so on. This study aims to suggest the business ecosystem model so that technology commercialization could be facilitated based on business ecosystem perspective. We set the framework for modeling a business ecosystem through reviewing the previous works, and draw several problems to be solved regarding public R&D commercialization in Korea from the perspective of ecosystem. Considering those, this research proposes the business ecosystem model for public R&D commercialization as a reference model for describing, discussing, and developing the technology commercialization strategy. The proposed model consists of 4 domains as follows: R&D, technology market, information distribution channels, and customers. The business ecosystem model shows that technology commercialization could be facilitated to create the market value through close relationship and organic cooperation among its members that form the ecosystem. Public research institutes as a keystone player could control the fate of the ecosystem. In this regard, this paper suggests roles of public research institutes for evolving the business ecosystem.

  • This paper reviewed the concept of the energy flow in east and west. The differences in the views of the energy flow between oriental and western thought were compaired according to the ontological point of view. Human body take up energy and material on open system which maintains homeostasis. Human and environment are continuously interacting in a state of co-existence. Human has energy field called "aura" and seven chakra in energy outflow moving came as meridian. Qi is an invisible cosmic energy helping the fundamental human activity and changes. The basic action of Qi is helping the human growth and development, maintain the body temperature and preventing the intrusion of microorganism. In the normal healthy organism, all are maintained in balance and in a continuous circulation of Qi, while illness is the result of the disturbed Qi flow in the aspect of Qi-theory. Although there are differences between oriental and western medicine in approaches to clients, the basic point of view and philosophy have many similarities on fundamental level. An understanding of the basic thought of energy flow and oriental concept of energy flow implies a more comprehensive meaning than the perspective of unitary transformation discussed in modern western thought of energy flow. Now we should avoid narrow view of energy concept and regard energy flow as an integrated concept with Korean culture. Regarding Qi-theory which provides a comprehensive and humanistic and ethical foundation for nursing philisophy through this overview, it is hoped that a contribution will be made to the development of nursing intervention which is suitable to Korean context.

  • This study attempted to develop integrated family policy. For this purpose, a delphi survey was conducted twice among 15 professionals regarding the general contents of family policy, the goals and outcomes of president Roh's administration, the direction and plan of action for future family policy. The results of this study are as follows: Firstly, the main results of president Roh's administration were the creation of the Ministry of Women and Families, and the Healthy Families Law. Nevertheless, that government had no long-term vision or action programs. Secondly, there are two aspects of family policy which one is family members based and the other is family life cycle based. Accordingly the subjects of this study insist that family policy has to cover people's whole life, all families regardless of family structure, and has to integrate the plans and programs which have been served to individuals, for example, women, child, youth, and elderly. Thirdly, the orientations of future family policy are to be toward happiness, health, equality, coexistence, harmony, growth, generosity, diversity, self-control, and a sustainable society. So the concept of the integrated family policy has to cover all aspects of the family and the diversity of family life. Therefore, the service delivery system for family policy has to converge into the Healthy Family Center.
