Background: When basic local governments want to improve their air quality management policies, they need fundamental evidence, such as the effectiveness of current policies or scenario results. Objectives: The purpose of this study is to lay the groundwork for a process to calculate air pollutant reduction from basic local government air quality policies and provide numerical estimates of PM_2.5 concentrations following improved policies. Methods: We calculated the amount of air pollutant reduction that can be expected in the research region based on the Gyeonggi-do Air Environment Management Implementation Plan issued in 2021 and guidelines from the Korean Ministry of Environment. The PM_2.5 concentration variations were numerically simulated using the CMAQ (photochemical air quality model). Results: The research regions selected were Suwon, Ansan, Yongin, Pyeongtaek, and Hwaseong in consideration of population, air pollutant emissions, and geographical requirements. The expected reduction ratios in 2024 compared to 2018 are CO (3.0%), NO_x (7.9%), VOCs (0.7%), SO_x (0.1%), PM₁₀ (2.4%), PM_2.5 (6.1%), NH₃ (0.05%). The reduced PM_2.5 concentration ratio was highest in July and lowest in April. The expected concentration reduction of yearly mean PM_2.5 in the research region is 0.12 ㎍/m³ (0.6%). Conclusions: Gyeonggi-do is now able to quickly provide air pollutant emission reduction calculations by respective policy scenario and PM_2.5 simulation results, including for secondary aerosol particles. In order to provide more generalized results to basic local governments, it is necessary to conduct additional research by expanding the analysis tools and periods.

Health impact assessment is implemented within the Environmental impact assessment for the purpose of minimizing health damage by predicting the impact on human health following implementation of the development project. In health impact assessment, manual revision is required due to the lack of consistency in the method of estimating hazardous air pollutants emissions. This study estimated the emissions by calculating the emissions of hazardous air pollutants based on the actual industrial complex development cases and completed health impact assessments. As a result of risk assessment based on exposure concentration using CALPUFF model, the risk assessment results were different for each of the emission estimation methods, and manual improvement on the emission estimation method is needed.

Background: Regular doctor visits are vital for hypertension patients, especially for who have never received hypertension medication or non-pharmacologic therapy. This study purposed to study factors affecting outpatient visits for patients diagnosed with hypertension. Methods: This study included 59,009 respondents with hypertension over 30 from 2019 Community Health Survey data. Outpatient visits were defined by having hypertension treatments such as medication or non-pharmacologic therapy. Logistic regression was used to examine the factors affecting outpatient visits using SAS ver. 9.3. Results: 57,081(96.73%) patients with hypertension were identified as those having a outpatient visit for hypertension treatments, whereas 1,928(3.27%) patients did not have visits. Patient's characteristics such as gender, age, periods of hypertension, education level, perception of the blood pressure, hypertension management education, place of living, body mass index, depression and diabetes were found to have statistically significant relationship with the outpatient visits. Practical Implications: There is a need to select patients with high blood pressure who are unlikely to visit for hypertension treatments based on the study results. For those, establishing a personalized management plan such as health education and counseling programs will be helpful for the successful implementation of national chronic disease management program.

The notion of technological adoption such as Radio Frequency Identification (RFID) has been examined in various domains such as supply chain management, inventory management and health care. However, there are several unanswered questions surrounding how this technology is adopted in disaster management. This study attempts to explore the potential of RFID in disaster management. The notion of Task-Technology Fit (TTF) is deemed suitable for this purpose and thus used as the theoretical framework that is further validated by employing multiple case studies. The empirical findings indicate that there are six key factors influencing the decision to adopt RFID in disaster management. Some relate to aspects of RFID when it is put into practice, namely cost, compatibility, standardisation, implementation and locatability; while the other key factor relates to privacy and security aspect of information. It is hoped that the findings of this research will inform disaster management organizations to better plan the adoption of RFID for their operations.

Objectives: Improvement of the reliability of work environment measurement results is one of the principal subjects to be resolved in the field of industrial hygiene. Thus, this study was conducted in order to review domestic programs for enhancing the reliability of work environment measurement results and propose a more efficient management plan for workplace monitoring. Materials and Methods: The current domestic programs reviewed in this study are the quality control system and evaluation system for industrial hygiene laboratories, the reliability system accompanied by KOSHA (the Korea Occupational Safety and Health Agency), the system of permissible exposure limits and observed inspection system for permissible exposure limits. Their contents and data were analyzed by reviewing articles, reports, and guidelines related to reliability improvement for work environment measurement results. Results: As a result of the literature review, all the domestic programs investigated in this study had both merits and demerits in terms of considering the reliability of work environment measurement results. In particular, the fact that preliminary notification is provided to the head of a workplace before implementation would be an obstacle for elevating the reliability of work environment measurement results. Conclusions: Based on the review results obtained from this study, it is proposed that on-site measurement without preliminary notification should be considered for a more efficient inspection system that would enhance the reliability of workplace monitoring.

Objectives: This study aims to examine the association of depression, suicidal behaviors with smartphone use behaviors among Korean adolescents. Methods: We analyzed data from 'Youth Health and Life Skills Survey' in 2013. The survey was based on self-reported questionnaires distributed to 915 grade 7th and 8th students at four middle schools in Gangdong-gu, Seoul, Korea in 2013 to evaluate the effects of 'Youth Health and Life Skills' program. Depression and suicidal behaviors were measured in terms of the experience rate, and smartphone use behaviors were measured with average hours of smartphone use a day and overindulged behaviors in smartphone use by using 5-point Likert scales. We examined the association of depression and suicidal behaviors with smartphone use behaviors by using t-test and regression analyses. Results: 21.5% of respondents have ever felt depressed or hopeless to lose interest in school life almost everyday for 2 weeks or longer in the past year. The experience rate of suicidal ideation, suicide plan, and suicidal attempt were 21.1%, 6.1%, and 5.7%, respectively. The mean of average hours of smartphone use a day was 3.9 hours, and the mean score of overindulged behaviors in smartphone use was 2.99. The students who have experienced depression and suicidal behaviors were more likely to have more smartphone using time and higher scores of overindulged behaviors in smartphne use than those who have not. Conclusion: We concluded that for preventing addictive or problematic smartphone use behaviors among adolescents we should consider and develop more positive strategies for the moderate use of smartphone than regulatory measures, which include the implementation of skill-based health education program including life skills at schools and the development of smartphone applications useful for resolving mental stress and promoting mental health.

To stem the ever-prevalent occurrence of industrial accidents in the construction industry, which is emerging as a social problem, efforts must be invested by various stakeholders. Specifically, among stakeholders, the orderer is at the top of a project's decision-making structure. Therefore, the orderer's awareness of safety and health directly affects the process of securing the safety of the overall construction site. In this light, the present study aims to identify differences in the perceptions of each stakeholder regarding the obligatory safety and health measures for clients that have recently been introduced. In addition, it suggests specific implementation plans in the Korean context. The data used for analysis were collected through a survey targeting stakeholders such as orderers, safety managers, and site managers, and the collected data were quantitatively reviewed by using multivariate analysis methods such as analysis of variance. As a result of the analysis, the introduction of safety and health obligations for the owner was found to be necessary, and the designation and operation of safety and health experts as an action plan was deemed reasonable. The authors expect that the results of this study can be used as basic data for revising the related regulations in Korea. Moreover, as a further study, a review of the effectiveness after improving regulations would contribute strongly to the domain.

Elderly population has increased rapidly and adjusting the environment is in demand to support their health. To improve the living environment of elderly, an appropriate plan for customized home modification is needed upon the personal contexts. The purpose of this study is to explain the sequence and to build an insight on customized home modification for vulnerable single elderly. It is a case study based on single target that includes 6 months of execution period deeply seeking the appropriate plan for implementation. The target is a male elderly aged 74 living in a single story detached house. The various research methods are applied in this study including exploratory, participatory, action and trade-off preference researches. The result shows that plan for home modification is complex outcome of interlocking uniqueness between residence environment and resident situation. If customized modification is targeted for residentially vulnerable social group, more sensitive approach aiming for the highest result is required due to financial constraint. To conclude, comprehensive understanding of overall circumstances of a dwelling, a resident and various stakeholder is essential throughout the process. Since the aging-in-place of elderly cannot be achieved without self-sustaining living environment, customized home modification should be a tool to meet housing suitability. It is important to strengthen the experts and future workforce with networks of local residents to share opinions and appropriate plans.
