Due to the expansion of non-face-to-face services, the demand for user identification for mobile devices is increasing. Recently, mobile resident registration cards, mobile driver's licenses, etc. are installed in mobile phones and used for user identification and authentication services. In order to identify a user online, unique identification information of the online user is required. In particular, in order to provide information only to online users, it is necessary to accurately deliver information to a mobile device owned by the user. To make this service possible, it was realized with the advent of mobile electronic notice service. However, the identification of online service users and information on mobile devices owned or subscribed by the relevant users require safe management as personal information, and it is also necessary to increase the convenience of online service users. In this paper, we propose an operating standard for providing a mobile electronic notice service that sends electronic notice using a mobile device owned by the user. The mobile electronic notice service is a service that provides notices expressed in electronic information to the recipient's cell phone, mobile app, e-mail, etc. Therefore, as the use of mobile electronic notification service increases and the provision and use of connecting information to identify users increases, it is necessary to expand the mobile electronic notification service while safely protecting users' personal information.

Recently, robots have been actively utilized for logistics and delivery services in various places such as restaurants, hotels, and hospitals. In addition, it provides a safer environment, convenience, and cost efficiency to the customers. However, when it comes to autonomous delivery in a multi-floor environment, the task is still challenging. Especially for wheeled mobile robots, it is necessary to deal with elevators to perform the last-mile delivery services. Therefore, we present a multi-floor route planning algorithm that enables a wheeled mobile robot to traverse an elevator for the delivery service. In addition, an elevator boarding mission algorithm was developed to perceive the drivable region within the elevator and generate a feasible path that is collision-free. The algorithm was tested with real-world experiments and was demonstrated to perform autonomous postal delivery service in a multi-floor building. We concluded that our study could contribute to building a stable autonomous driving robot system for a multi-floor environment.

Purpose: To examine the economic effects of logistics under the influence of policies. Research design, data and methodology: This study is the first to use the panel data of 31 provinces and municipalities in China from 2012 to 2021, and use the OLS and DID models to evaluate whether the New Western Land-Sea Corridor (NWLSC) has promoted the economic development of the regions along the corridor. Results: The NWLSC has stimulated local economic growth by promoting the development of transportation, postal, and telecommunications industries along the corridor. Further, considering the locational differences of the regions along the NWLSC, we examined the differences in economic effects between regions along the Yangtze River and those not along the Yangtze River under the background of NWLSC implementation. We found that waterway and airway transport located along the NWLSC and in the Yangtze River Economic Belt (YREB) region can significantly promote economic growth. However, for regions located along the NWLSC but not in the YREB region, the impact of roadway, railway, and airway transport in these regions on economic growth is more significant. Conclusions: This study has important reference value on how to use logistics to promote the economic and cross-border commerce development of landlocked countries or regions.

The unique characteristics of the construction industry - such as the fragmentation of its processes, varied scope of works and diversity of its participants - are contributory factors to poor project performance. Several issues are unresolved due to the lack of a comprehensive technique to measure project outcomes including: inefficient decision making, insufficient communication, uncertain site conditions, a continuously changing environment, inharmonious working relationships, mismatched objectives within the project team and a blame culture. One approach to overcoming these problems appears to be to measure performance by gauging contractor satisfaction (Co-S) levels, but this has not been widely investigated as yet. Additionally, the key Co-S dimensions at the project level are still not fully identified. This paper concerns a study of satisfaction dimensions, primarily by a postal questionnaire survey of construction contractors registered by the Malaysian Construction Industry Development Board (CIDB). Eight satisfaction dimensions are identified that are significantly and substantially relate to these contractors - comprising: project cost performance, schedule performance, product performance, design satisfaction, site safety, project profitability, business performance and relationships between participants. -Each of these dimensions is accorded different priority levels of satisfaction by different contractors. The output of this study will be useful in raising the awareness and understanding of project teams regarding contractors' needs, mutual objectives and open communication to help to deliver a successful project.

The purpose of this study was to investigate foodservice management practices in the child care centers and kindergartens. Interviews were held from May to July 2008 to understand the current situation concerning foodservices in Seoul and Gyeonggi provinces. Surveys were sent out from August 2008 to April 2009 to 1,478 child care centers and 299 kindergartens via the postal service. Among them, 203 child care centers(13.7%) and 64 kindergartens(21.4%) responded. One of the largest concerns while preparing the food was nutrition(68.7%, 69.8%, respectively) followed by sanitation(24.4%, 27.0%, respectively). The most frequently referred sources for planning the menu were the Seoul child care information center(55.4%) for child care centers and kindergarten related internet sites(39.0%) for the kindergartens. In general, the child care center principal was in charge of planning the menu(40.1%). Child care centers and kindergartens purchased ingredients mostly from large retailers(55.3% and 44.7%, respectively), whereas 46.0% and 56.3% of those did through foodservice suppliers. Dietitians were rarely employed at these facilities, and this may cause unprofessional foodservice management.

Purpose: The purpose of this study was to investigate work performance and calling as determinants of job satisfaction among nurse midwives. Methods: The participants of this study were registered nurse midwives who had worked in the delivery room for more than 6 months. Data were collected by face-to-face interviews, postal mail, and mobile devices. Subjects completed self-report questionnaires from July to August 2017. The dataset was analyzed using descriptive statistics, the independent t-test, analysis of variance, the Pearson correlation coefficient, and multiple regression. Results: The mean score for job satisfaction was 3.42±0.45. Among the sub-factors, income had the lowest score (2.67±0.72) and management of delivery had the highest score (3.81±0.66). Job satisfaction was significantly different according to marital status (t=2.25, p=.028), residential area (t=2.43, p=.016), and cause of job satisfaction (F=4.54, p=.012). Job satisfaction showed a significant positive correlation with work performance (r=.29, p<.001) and calling (r=.57, p<.001). The correlation between work performance and calling was also positive and statistically significant (r=.32, p<.001). Purpose and meaning (β=.48, p<.001) and marital status (β=-.15, p=.025) significantly influenced job satisfaction. The model developed in this study explained 45% of variation in job satisfaction. Conclusion: Nurse midwives' job satisfaction may be enhanced by entrusting them with professional roles and tasks. Above all, it is necessary to develop and provide programs that help nurse midwives connect their jobs with the meaning and purpose of their lives.

Purpose: The purpose of this study was to describe the status of maternity protection in the industries for the development of educational database used by occupational health nurses (OHNs). Method: 100 OHNs were purposively sampled and they were charged in the occupational health manager of their own industries. Data were collected by the postal mail, the response rate was 53.0%, and analysis rate was 43.0%. Result: The results were as follows; 1. Most of subjects responded there was the institutionalization of a special holiday for woman workers (97.7%) and 90 days maternity leave (95.4%). Otherwise, the numbers of industry were smaller in the case of providing the breast-feeding time, temporary rest from office for child raring, restriction of hazard job, night job, and over time. The application rates were lower than the rate of institutionalization of all maternity protection items. 2. There were significant differences in institutionalization of maternity protection by the activity of the trade union. And the numbers of the industry applying the maternity protection were significantly different by the area and the types of industry. 3. Most OHNs responded 17 subjects were needed to the maternity protection education for women workers. Conclusion: It would be needed to develop the maternity protection education database in base of the status of maternity protection in the industries and the need of maternity protection education. The role of OHNs for maternity protection was expected to activate.

이 연구는 소설이 허구의 세계이지만 당시의 사회상을 반영한다는 전제에서 9편의 신소설을 통하여 개화기 일반 백성들의 다양한 인간 커뮤니케이션 양태를 분석하였다. 분석 결과 개화기 인간 커뮤니케이션의 가장 큰 특징은 신문과 서적, 우편, 전보, 전화, 사진 등 새로운 매체의 출현으로 커뮤니케이션 환경이 다양화되었다는 점이다. 새로운 매체들이 출현하기는 했지만 아직도 구두 커뮤니케이션에 의존하는 전통적 방식이 중심이 된 것으로 볼 수 있겠다. 구두 커뮤니케이션에서 신분과 연령이 가장 큰 변수가 된 점은 조선 후기와 같았지만 격식과 예법은 많이 완화되었다. 또한 문자 문화의 기반이 대폭 확대되었다. 새로 등장한 매체들도 대부분 문자를 기반으로 하는 것들이며 여성이나 천민 계층에서 한글 사용이 늘어났다. 개항으로 외국과의 교류가 가능해짐으로써 그 시대 사람들의 생활 세계가 확대되며 문화 간 커뮤니케이션도 이루어져 필담이나 통역 등의 형태도 등장하게 되었다. 결론적으로 개화기의 인간 커뮤니케이션 양태는 여전히 구두 커뮤니케이션에 주로 의존하면서도 새로운 미디어에 대한 의존이 점차 높아지기 시작하여 원거리 커뮤니케이션도 신속하게 가능해졌으며 문호 개방에 따라 커뮤니케이션의 영역과 범위도 확대되며 그 방법도 다양해졌다고 평가할 수 있겠다.

Objectives : We intended to evaluate the double standard status and to identify factors of determining double standard criteria in multinational corporations of Korea, and specifically those in the occupational health and safety area. Methods : A postal questionnaire had been sent, between August 2002 and September 2002, to multinational corporations in Korea. A double standard company was defined as those who answered in more than one item as adopting a different standard among the five items regarding double standard identification. By comparing double standard companies with equivalent standard companies, determinants for double standards were then identified using logistic regression analysis. Results : Of multinational corporations, 45.1% had adopted a double standard. Based on the question naire's scale level, the factor of 'characteristic and size of multinational corporation' was found to have the most potent impact on increasing double standard risk. On the variable level, factors of 'number of affiliated companies' and 'existence of an auditing system with the parent company' showed a strong negative impact on double standard risk. Conclusion : Our study suggests that a distinctive approach is needed to manage the occupational safety and health for multinational corporations. This approach should be focused on the specific level of a corporation, not on a country level.
