  • As various methodologies for business process analysis and design have been conducted in many organizations by their own ways, those methodologies are not compatible each other. In order to reduce the cost of analysis for organizations. some mapping methods between different methodologies need to be developed. UMM(UN/CEFACT Modeling Methodology) that has an object-oriented point of view. can overcome the limits of existing bottom-up approaches and make it reasonable. It also simplifies the business and administrative procedures. IDEF( Integrated Definition Language) with a structural point of view that has been widely used as a system analysis and design method, needs to be mapped to UMM in order to reuse the existing IDEF models. In this study, we propose a guideline that deals with procedures of utilizing IDEF models from which we want to derive the UMM models for developing an electronic commerce system including electronic documents exchange. By comparing IDEF and UMM, we analyze the differences between those two methodologies. Based on these differences. we suggest the basic strategies for mapping method from IDEF to UMM. We also propose a mapping guideline that can make UMM results from the modeling results of IDEF. We can take an advantage of the existing IDEF analysis design results when we adopt UMM methodology for electronic business system. Many analysts who are familiar with the IDEF methodology can develop UMM work-flow by utilizing their existing results and skills.

  • When a competent employee leaves an organization, the technical skills and know-how possessed by that employee also disappear, which may lead to various problems, such as a decrease in organizational morale and technology leakage. To address such problems, it is important to increase employees' job satisfaction. Due to the advancement of both information and communication technology and social media, many former and current employees share information regarding companies in which they have worked or for which they currently work via job portal websites. In this study, a web crawl was used to collect reviews and job satisfaction ratings written by all and incumbent employees working in nine industries from Job Planet, a Korean job portal site. According to this analysis, regardless of the industry in question, organizational culture, welfare support, work system, growth capability and relationships had significant positive effects on job satisfaction, while time and attendance management, performance management, and organizational flexibility had significant negative effects on job satisfaction. With respect to the path difference between former and current employees, time and attendance management and organizational flexibility have greater negative effects on job satisfaction for current employees than for former employees. On the other hand, organizational culture, work system, and relationships had greater positive effects for current employees than for former employees.

  • The present study tested a multivariate model of direct and indirect influences of family Socioeconomic Status (SES) on children's early reading skills at kindergarten entry. The data used here are from one of the largest national databases in the USA, the Early Childhood Longitudinal Study-Kindergarten cohort (ECLS-K). Utilizing structural equation modeling, the results revealed that a number of factors within parental characteristics, home practices, and SES come together to influence children's early reading skills. SES operated primarily indirectly through home literacy activities and also directly in influencing reading. In addition, parental beliefs about kindergarten readiness mediated the relation between SES and home literacy activities. Thus, SES influenced early reading directly and indirectly, through home literacy activities, and simultaneously, through parental beliefs, which in turn, were associated with home literacy activities that were directly associated with children's reading. The findings emphasized the multiple pathways through which SES is associated with children's reading and the need to search for other mediators of SES influence.

  • The purpose of this study was to explore, using topic modeling, the social value of doctors and medicine demanded by society as reflected in published newspaper articles in Korea. Ultimately, this study aimed to reflect social needs in the process of developing the Patient-Centered Doctor's Competency Framework in Korea. For this purpose, a total of 2,068 newspaper articles published from 2016 to 2020 were analyzed. Through topic modeling of these newspaper articles over the past 5 years, 18 topics were derived and divided into four categories. Focusing on the derived topics and keywords, the topics derived in specific years and the proportion of topics by year were analyzed. The results of this study make it possible to grasp the needs of society projected through the press for doctors and medicine. Due to the nature of the press, topics that frequently appeared in newspaper articles were mainly social phenomena related to requirements for doctors, particularly dealing with economic and legal aspects. In particular, it was confirmed that doctors are now required to have a wider range of competencies that go beyond their required medical knowledge and clinical skills. This study helped to establish doctor's competencies by analyzing social needs for doctors through the latest research methods, and the findings could help to establish and improve doctor's competencies through ongoing research in the future.

  • This study assessed 1) the coverage of the entry-level responsibilities and competencies for certified health education specialists (CHES) developed in the United States (U.S.) by 140 current health education-related professional preparation programs in Japan, and 2) barriers and concerns related to the development of Japanese health educators. A cross-sectional survey study was conducted to Japanese professors teaching health education-related courses at 4-year universities/colleges in Japan. All entry-level CHES responsibilities and competencies were generally covered to different degrees by the study respondents. The top 3 responsibilities most emphasized by the respondents were Responsibilities I, related to need assessment skills, Responsibility II, related to planning health education programs, and Responsibility III, related to implement health education programs. The 3 competencies most frequently covered by the respondents were related to needs assessment skills (Competencies 1-3). The competencies least covered by the respondents were those related to Responsibilities V (Competencies 1619). Other competencies related to role modeling, cultural competencies, and planning youth health education programs, were recommended. In addition, the major concerns and opinions that the respondents reported for this topic pertained to 1) Professional training, 2) The need for well-defined professional roles, and 3) The importance of licensing. The results suggested that Japanese health education-related programs cover all CHES responsibilities and competencies developed in the U.S. to different degrees. However, they tend to focus more on needs assessment, planning and implementing health education programs. Although possible responsibilities for future Japanese health educators were recommended, further research to identify the most appropriate responsibilities and competencies for this profession is needed. Major barriers, concerns and opinions reported by the respondents should be discussed at future meetings for this profession.

  • The domestic and foreign standards of school libraries suggest that school library should be run to give useful and pleasant experiences to students. This study applies Csikszentmihalyi's 'flow theory' to analyze the relationships between students' flow experience and their satisfaction about school libraries use. The variables selected in this study are students' satisfaction, flow experience, library skill, challenge of library use, types of library use and students' learning styles. The research model is designed by using these 6 variables in this study. The data are collected from 293 students and analyzed by structural equation modeling. The results of this study are as follows: The entire casual relationships show that library skills influence in types of library use, types of library use affect students' learning styles and students' learning styles influence in satisfaction through flow. To improve students' satisfaction about school library use, this study proposes effective ways related to teacher librarians' role performances to expand students' flow experience and increase their library skills.

  • For more than 2,500 years, surgical teaching has been based on the so called "see one, do one, teach one" paradigm, in which the surgical trainee learns by operating on patients under close supervision of peers and superiors. However, higher demands on the quality of patient care and rising malpractice costs have made it increasingly risky to train on patients. Minimally invasive surgery, in particular, has made it more difficult for an instructor to demonstrate the required manual skills. It has been recognized that, similar to flight simulators for pilots, virtual reality (VR) based surgical simulators promise a safer and more comprehensive way to train manual skills of medical personnel in general and surgeons in particular. One of the major challenges in the development of VR-based surgical trainers is the real-time and realistic simulation of interactions between surgical instruments and biological tissues. It involves multi-disciplinary research areas including soft tissue mechanical behavior, tool-tissue contact mechanics, computer haptics, computer graphics and robotics integrated into VR-based training systems. The research described in this paper addresses the problem of characterizing soft tissue properties for medical virtual environments. A system to measure in vivo mechanical properties of soft tissues was designed, and eleven sets of animal experiments were performed to measure in vivo and in vitro biomechanical properties of porcine intra-abdominal organs. Viscoelastic tissue parameters were then extracted by matching finite element model predictions with the empirical data. Finally, the tissue parameters were combined with geometric organ models segmented from the Visible Human Dataset and integrated into a minimally invasive surgical simulation system consisting of haptic interface devices and a graphic display.
