This study intends to suggest a method for analyzing the vulnerability of fine dust nationwide by considering spatial information on fine dust and recent policy trends. As a result of national adsorption analysis, it was highly distributed in areas with many forests or green areas. Most of the areas with high vulnerability due to low adsorption amount were analyzed to be metropolitan areas and metropolitan cities with high population density and low amount of green space. A key management area was derived through spatial analysis of adsorption amount, concentration, and emission. Areas classified as very vulnerable areas seem to have to come up with policy measures within the local government, and management should be prioritized. Areas of moderate vulnerability and low vulnerability require constant monitoring and continuous maintenance of green areas. It is meaningful in that it analyzes the vulnerability of fine dust in the country in terms of risks to human health and the physical aspects that the region can accept, and has the advantage of intuitively exploring areas with insufficient capacity compared to the amount of fine dust. Since the vulnerability of fine dust was analyzed nationwide, it is highly useful as basic data in the policy decision-making process.

강다인(DA IN KANG),이지연(JI YEON LEE) 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.22

목적 본 연구에서는 코로나 19기간 동안 유자녀 여교사들을 대상으로 일-가정 양립갈등, 직업평판, 소명의식, 괜찮은 일의 관계를 확인하여 구조방정식 모형과 일-가정 양립갈등, 직업평판과 소명의식의 관계에서 괜찮은 일의 매개효과를 검증하고자 하였다. 방법 이를 위하여 온라인으로 전국의 유자녀 여교사 286명을 대상으로 일-가정 양립갈등, 직업평판, 소명의식, 괜찮은 일을 측정하는 척도로 구성된 설문을 실시하였고, 응답자료 중 최종 249개를 분석에 사용하였다. 수집된 자료는 SPSS20.0과 AMOS26.0을 사용하여 구조방정식모형을 통해 분석하였다. 결과 수집된 자료를 분석한 주요 결과는 다음과 같다. 첫째. 본 연구의 주요 변인들 간의 상관분석을 실시한 결과 일-가정 양립갈등과 직업평판은 유의미한 부적 상관관계가 있는 것으로 나타났다. 둘째, 일-가정 양립 갈등과 괜찮은 일은 상관관계분석 실시 결과 정적 상관관계가 있는 것으로 나타났는데 최종 모형에서도 일-가정 양립갈등은 괜찮은 일을 정적으로 예측한다는 결과가 지지되었다. 셋째, 코로나19기간 동안 일-가정 양립 갈등과 여교사가 인식하는 직업평판이 소명의식에 이르는 경로에서 괜찮은 일의 매개효과에 대한 유의성을 검증한 결과, 괜찮은 일이 일-가정 양립갈등과 직업평판을 완전 매개하는 것으로 나타났다. 이러한 연구결과에 비추어 보면 일-가정 양립갈등과 직업평판이 각각 괜찮은 일을 매개로 소명의식에, 소명의식에 영향을 주는 것으로 나타났으며, 일-가정 양립갈등/직업평판과 소명의식의 관계에서 괜찮은 일은 완전매개효과의 영향을 주고 있음을 의미한다고 볼 수 있다. 결론 코로나19 기간 동안 여교사가 자신이 경험하는 일-가정 양립갈등과 직업평판이 소명의식으로 향하는 경로에서 괜찮은 일의 매개효과가 나타나는지를 살펴봄으로서 소명의식을 수행하는 선행기제를 파악하고 상담 개입방법의 기초적인 자료를 제공하고자 하였다. Objectives In this study, the relationship between work-family balance conflict, job reputation, sense of calling, and decent work was checked for female teachers with children during the COVID-19 period, and the relationship between the structural equation model and work-family coexistence conflict, job reputation and sense of calling was positive. The purpose of this study was to verify the mediating effect of work. Methods For this purpose, an online questionnaire consisting of scales measuring work-family balance conflict, job reputation, sense of calling, and decent work was conducted for 286 female teachers with children across the country, and the final 249 responses were used for analysis. The collected data were analyzed through the structural equation model using SPSS20.0 and AMOS26.0. Results The main results of analyzing the collected data are as follows. first. As a result of a correlation analysis between the major variables in this study, it was found that there was a significant negative correlation between work-family balance conflict and job reputation. Second, the results of correlation analysis showed that there is a positive correlation between work-family balance conflict and decent work, and the final model also supported the result that work-family balance conflict positively predicts decent work. Third, as a result of examining the significance of the mediating effect of decent work on the path from work-family balance conflict and female teachers' perceived job reputation to a sense of vocation during the COVID-19 period, decent work is associated with work-family balance conflict and job reputation. appeared to be completely mediated. In the light of these research results, it was found that work-family balance conflict and job reputation influence the sense of calling and calling through good work, respectively, and in the relationship between work-family balance conflict/professional reputation and the sense of calling It can be said that good work is influencing the perfectly mediating effect. Conclusions By examining whether the mediating effect of a decent job appears on the path that female teachers experience during the COVID-19 period, the work-family reconciliation conflict and professional reputation on the path toward the sense of vocation, it is necessary to identify the preceding mechanism for carrying out the vocation and the basis of the counseling intervention method. It was intended to provide relevant data.

This study aims to understand the relationship between visitors and the degradation of natural resources in Bukhansan national park. We analyzed the trend of the number of visitors, destruction of natural resources and decrease of biodiversity per year. We further compared three types of trails, heavily-used trails and rarely-used trails and a trail with limited access, regarding the degree of destruction in the National Park through a field survey. Our result showed that increasing number of visitors had direct and indirect impact on the destruction of natural resources in the National Park. The direct impact came from visitors`` excessive use of trails. Naturally, increasing number of visitors caused an immoderate use of natural resources. Physical degradation such as exposure of tree root, poor drainage of trails, trail erosion was more severe than other types of trails. Decreasing biodiversity or mild disturbance around trails is the indirect impact such as broken bough, worn-bark in rarely-used trails. Destruction scale greatly increased as the number of visitors increased. Real-named reservation system helped to prevent trails from degradation. Our result calls for the need of controlling the number of visitors to Bukhansan National Park to mitigate the degradation. We recommend dispersing visitors from the heavily-used trails to other trails and implementing real-named reservation system in the rarely-used trails for the effective management of the national park.

Urban green spaces supply ecosystem services (ESs), which are consumed by city residents and generate demand, to improve air quality. It is important to determine supply and demand for ESs and reduce the gap for efficient management. This study proposed a method to use the concept of supply and demand for ESs in the decision-making process for urban planning or management. PM10 concentrations were converted to weight for demand assessment on PM10 reduction, and PM10 absorption capacity of all green spaces including the forests, and that of urban green spaces excluding forests, was calculated for each supply assessment. The differences in the calculated supply and demand were analyzed to derive the mismatched regions in Suwon. As a result, regions with big forested areas showed sufficient supply, indicating that the degree of mismatch among administrative neighborhoods (dong) varied greatly depending on whether they had a forest. An analysis of only urban green spaces showed that all neighborhoods lacked supply. Forests with high PM10 absorption capacity had a great effect, but urban green spaces can be considered a key element in reducing PM10 in daily life. Considering the mismatch of supply and demand, spatial distribution, and population distribution, it is possible to prioritize the supply of urban green spaces to reduce PM10 and, furthermore, support decision making for priority zones subject to forest conservation and designation and cancellation of green spaces, which gives significance to this study.

Citizen participation data has different characteristics from expert. Understanding the unique attributes of citizen participation data and considering the disparities between such data and that collected by experts is of paramount importance to harness citizen-generated data effectively. In this regard, location information was presented for five taxa of plants, insects, birds, amphibians, and mammals nationwide surveyed by citizens in 2022, excluding endangered species. Additionally, species information and administrative district information are included. It is anticipated that the integration of citizen participation survey results with expert research findings will enhance the efficacy of natural ecological monitoring. By directly collecting ecological data, which becomes the basic data for natural environment policy, opportunities for public participation in natural environment policy will be expanded, and through this, it will be possible to raise awareness of natural environment conservation.

본 논문에서는 현재 양산되고 있는 Red(621 nm), Green(530 nm), Blue(453 nm), Amber(590 nm) 등 4파장의 LED 조합을 이용하여 색온도가 가변되는 동안에도 평균연색지수 및 특별연색지수 R9 값이 높게 유지될 수 있도록 조명의 스펙트럼을 최적화하였다. 최적화 시 설계의 정확도를 높이기 위하여 실제 측정한 LED 스펙트럼을 사용하였고 광선과 기구물 사이의 상호 작용을 고려한 광선 추적 기법을 활용하여 수행하였다 또한 최적화 결과를 검증하기 위하여 색온도 가변 조명 장치를 직접 제작하였으며 광 특성을 평가한 결과 색온도가 3000 K에서 6000 K까지 변하는 동안 CRI 및 R9 값이 각각 87~90, 34~93을 나타내었다. In this paper the spectra of correlated color temperature (CCT) tunable white light-emitting diode (LED) luminaires, consisting of commercial red, green, blue, and amber LED chips, were optimized to increase color rendering index (CRI), and a special CRI of R9 for deep red color was obtained. To improve the design's accuracy, measured LED spectra were used instead of mathematically modeled ones. Real CCT tunable LED luminaires with CRIs of 87-90 and R9s of 34-93 were fabricated and demonstrated at CCTs of 3000-6000 K.

Purpose: The incidence of high-risk pregnancies is increasing in Korea as the birth age increases due to late marriage. Maternal-fetal attachment is an important factor that affects children even after childbirth, but it is difficult for high-risk pregnant women to form maternal-fetal attachment. The current study aimed to explore whether taegyo practice (i.e., pregnant women’s efforts for fetal good growth and development), self-esteem, and social support influenced the degree of maternal-fetal attachment in women with high-risk pregnancies.Methods: The participants included 226 pregnant Korean women at ≥20 gestational weeks, hospitalized with 15 high-risk pregnancy conditions as defined by the Ministry of Health and Welfare. Recruitment via convenience sampling was done at four sites in Busan, Korea. Surveys were distributed and collected from February 1 to 28, 2022. Data analysis was conducted using descriptive statistics, the t-test, one-factor analysis of variance, Pearson correlation coefficients, and hierarchical multiple regression. Results: On average, participants were 33.97±4.23 years of age and at 31.65±6.23 gestational weeks. Preterm labor (35.4%) and gestational diabetes (21.0%) were the most common high-risk conditions. Maternal-fetal attachment was positively correlated with taegyo practice (r=.70, p<.001), self-esteem (r=.53, p<.001), and social support (r=.53, p<.001), all with statistical significance. Taegyo practice (β=.50, p<.001) and social support (β=.17, p=.030) explained 53% of variance in maternal-fetal attachment in women with high-risk pregnancies.Conclusion: Nurses caring for women with high-risk pregnancies during hospitalization can use these findings by promoting taegyo practice and enhancing social support to increase maternal-fetal attachment.
