Researchers recognized air pollution changes causing diseases and difficulties in living due to environmental pollution following various human activities, and have studied how to avoid fine dust harmful to the human respiratory system to be healthy. To this end, Arduino is used to equip fine dust level sensors in drones to measure the fine dust levels, visualize the measurements with LED indicator colors depending on the measurements to inform users of the danger of fine dust, and use the benefits of drones to specify dangerous fine dust zones and measure the fine dust levels. Users can see the changes depending on the fine dust levels in real time with the LED indicators. This will contributes to measuring fine dust levels easily in dangerous areas. Mission Planner (ArduPilot) is used to set up the GPS of drone, and store the data from the dust sensor as contents. This study aims to establish a method for improving the environment to measure fine dust levels with drones with LED indicators for fine dust, and reduce fine dust.

In recent, a general trend is observed towards more customized products and shorter product life cycles in manufacturing companies. In these companies, customers often wish to influence the product they order and to get a variant of product that meets their requirements. This environment is called as a customer-oriented manufacturing companies. This paper presents a procedure of product specification management for customer-oriented manufacturing companies by using product specification framework. This framework is founded on the product specification based product structure which is made of model, specification, function, and part. Also, a product specification management system(PSMS) is implemented by using the proposed product specification framework and is a core system in product data integration system. To illustrate an utilization of the proposed framework and procedure, a case of a ship engine product is applied. As a result, PSMS reduces delivery time and improves customer relationships. Moreover, the case shows that PSMS can be used as a tool for improving inter-department coordination within a company during product life cycle.

Due to the rapid changes in world trade and shipping environment, today's ports face ever-increasing competition, from adjacent competing ports. To this reason, port service quality has been recognized as an important strategy to take competitive advantage for those competition. In general, service quality has effect on customer loyalty, and customer loyalty is the resource to sustain competitive advantage which service providers or service producers. By improving customer loyalty, companies can get more benefits and added value. However, this causality qf port service quality has not been clearly identified. Thus, various empirical studies in relation to port service quality are needed. The aim of this study is to analyze the effect of perceived port service quality on customer satisfaction and loyalty. To achieve this aim, we established 8 hypotheses based on SERVPERF in order to test correlations of 5 dimensions of port service, port service quality, customer satisfaction, and customer loyalty. From the result of the hypothesis testing, we found that customer satisfaction and port service quality do not affect customer loyalty in spite of high effect of port service on customer satisfaction.

This study intended to suggest Voluntourism as a solution for alternative rural tourism for regional activation. Voluntourism is a form of alternative tourism on values of variety of tourism demand from pleasure to virtue. This study analyzed actual state of WWOOF(World-Wide Opportunities on Organic Farms) activities being operated in Korean rural village, one of representative of Voluntourism. Study aimed to explore the possibility of WWOOF activity as one of model of alternative rural tourism. We apply grounded theory method one of qualitative study methods for analysis of WWOOF Activities because WWOOF is still small activity in Korea. In result, we figure out the actual condition of WWOOF Korea activities as a vouluntourism through paradigm model of host and guest who had experience in WWOOF Korea. WWOOF activity is in its early stage so there many tasks. We suggested ideas for improving WWOOF activities to be one of new rural tourism business.

Purpose: The supply of and demand for medical services continue to increase as the current social environment changes. Consequently, competition among medical institutions is intensifying and hospitals must establish appropriate management strategies to improve the medical services they provide. This study suggests that the authenticity of doctors is a factor in improving medical-service quality and examines the effect authenticity has on the affective trust and satisfaction of patients. Design, methodology, and approach: The study utilized previous studies to examine the significance of potential variables, established hypotheses and used a questionnaire to confirm these hypotheses. The questionnaire was distributed to patients who had visited a hospital in the previous six months. Responses were analyzed empirically using structural equation modeling. Findings: The analysis found that a physician's authenticity has a significant impact on the affective trust of patients. While patients' affective trust does not have a similar strong impact on patient satisfaction, physician authenticity does have a significant impact on patient satisfaction. Conclusion and implications: This study examined the roles of authenticity, affective trust, and patient satisfaction in doctor-patient relationships in the medical services field. The implication of the findings is that physician authenticity is a prerequisite for patient satisfaction of medical services.

The purpose of this study was to examine the effect of two-dimensional factor of motivators and hygiene on civil servants' job satisfaction using the partial least square structural equation modeling (PLS-SEM) as a technique employed to analyze the measurement and structural models. Exploratory study was deployed to evaluate the relationship among variables. By using multistage stratified sampling, statistical data was collected from a survey of 441 public municipal civil servants who have employed in various levels (municipal government, districts and communes) in Vietnam. The findings provided evidence that hygiene factors (relationship with leader, salary, relationship with coworker and working environment) directly impact on civil servants' job satisfaction. Meanwhile, only career development factor from motivators significantly influenced on public employee's job satisfaction. Based on the empirical results, the hygiene factors of job satisfaction are more dominated that the motivators one. This finding suggests that municipal governments should focus policies on improving the hygiene factors which lead to higher job satisfaction on civil servants. Gaining a thorough understanding of the determinants of job satisfaction toward municipal public servants will enable policy makers to grasp the factors that results in retaining employees. Finally, the policy makers can use this knowledge to promote civil servants' job satisfaction.

Purpose - It is important to figure out the relationship between tourism carbon emissions and tourism economics for a healthy tourism development. Research design, data, and methodology - Data of this study are collected from 27 provinces (cities) of China. Tourist consumption stripping coefficient is used to calculate tourism carbon emissions. SBM-Undesirable model is used to measure the efficiency of tourism economics under the constraint of tourism carbon emissions. Results - The results show that: during the year of 2005-2015, there are obvious differences in totals and intensities of tourism carbon emissions among 27 provinces and cities which can be divided into three areas. There is a high possibility of underestimating the actual efficiency of tourism economics by leaving tourism carbon emissions out of account, and a high inefficiency caused by tourism carbon emissions will lead a low efficiency of tourism economics. Conclusions - The development of tourism should give consideration to both economic and environmental benefits, and reduce the inefficiency caused by tourism carbon emissions to improve efficiency of tourism economics by improving the level of technical efficiency and promoting technological progress.
