Factors Influencing Retention Intention of Nurses at Long-term Care Hospitals in Korea

Purpose: This study aimed to investigate the levels and correlations of role conflict, nursing professionalism, nursing work environment and retention intention, and the factors influencing retention intention of nurses at long-term care hospitals. Methods: The subjects included 183 nurses at nine long-term care hospitals in one metropolitan city in Korea. A set of self-reported questionnaires was administered to assess general characteristics, role conflict, nursing professionalism, nursing work environment, and retention intention of the subjects. Collected data was analyzed using descriptive statistics, t-tests, one-way ANOVA, Pearson correlation coefficients, and multiple linear regression. Results: 183 subjects with a mean (±SD) age of 41.66 (±12.29) years were included in the final analyses. Retention intention had a significant positive correlation with nursing professionalism (r=.39, p<.001) and nursing work environment (r=.51, p<.001). Nursing work environment had a significant negative correlation with role conflict (r=-.30, p<.001) and a significant positive correlation with nursing professionalism (r=.48, p<.001). In the final multiple regression analysis, the factors influencing retention intention of subjects were number of beds (β=-.15 p<.026), nursing professionalism (β=.19, p=.007) and nursing work environment (β=.36, p<.001). The explanatory power of number of beds, nursing professionalism and nursing work environment on retention intention was 34.0% (F=16.66, p<.001). Conclusion: Improving nursing professionalism and nursing work environment of nurses at long-term care hospitals will ultimately enhance their retention intention and positively impact on the quality of gerontological nursing service.

관광산업체 종사원의 심리적 자본과 직무성과와의 구조적관계 연구

The purpose of this study is to examine the relationship between psychological capital (confidence, hope, resilience, optimism) and job performance of tourism industrial workers. In order to achieve the purpose of this study, a survey was conducted targeting employees of tourism industry in 10 cities in korea. The survey was conducted over a period of about one month from May 1, 2021 to June 1, 2021. 150 copies of the questionnaire were distributed, and 145 copies were used as final analysis data. Analysis result using SPSS 23.0 program and AMOS 23.0 program, Among the psychological capital of tourism industry employees, ‘confidence’ and ‘hope’ form a positive (+) influence relationship on job performance (job satisfaction, organizational commitment), Hypothesis1-1, Hypothesis1-2, Hypothesis2-1, and Hypothesis2-2 was adopted. However, as the relationship between resilience and optimism among psychological capitals did not form a positive (+) effect on job performance (job satisfaction, organizational commitment), Hypothesis1-3, Hypothesis1-4, Hypothesis2-3, and Hypothesis2-4 were rejected. Through this study, psychological capital of tourism industry employees was confirmed as 'confidence' and 'hope'. It is suggested that the tourism industry needs a management strategy for human resource management that can strengthen 'confidence' and 'hope' among employees' psychological capital in order to maximize business performance and improve employees' quality of life.

Urban gentrification, social vulnerability, and environmental (in) justice: Perspectives from gentrifying metropolitan cities in Korea

By integrating urban gentrification dynamics with nexus of social vulnerability and environmental (in)justice, this study explores gentrification processes and community perceptions of gentrification outcomes across gentrifying areas within metropolitan areas corresponding to seven selected cities within South Korea. Combined with redefined urban gentrification drivers, mediators (or control variables), and outcomes, correlation analysis was undertaken using longitudinal secondary data and cross-sectional survey data. Such case study-based empirical approaches in a non-western context were applied to measure social vulnerability and environmental (in)justice index, map spatial distribution of the index, and address the relationships among the gentrification processes in the context of social vulnerability and environmental (in)justice. Our results suggest that a positive correlation between social vulnerability to gentrification and environmental (in)justice exists particularly in urban core areas. Gentrification outcomes by community perceptions exhibited increases in house sale price and household displacement. Our attempts can provide policymakers, planners, practitioners, and residents with a better understanding of social and environmental constraints or benefits of gentrification along with the important concepts of social vulnerability and environmental justice as solutions to urban regeneration challenges.

Lifestyle segmentation of older Koreans: a longitudinal comparison of segments and life satisfaction

PurposeAging is a global phenomenon for many countries, and South Korea has become the fastest aging country in the world. The purpose of this study is to identify and validate a representative typology of older Koreans based on their lifestyle and value orientations. This study also makes a longitudinal comparison of these segments in two waves using similar survey data collected in 2009 and 2017 and examines any meaningful changes that occurred during the periods.Design/methodology/approachUsing survey data collected from 750 older adults living in four major cities in Korea, this study conducted factor and cluster analysis to identify lifestyle segmentation of elderly Koreans. Both descriptive and mean comparison analyses are followed to characterize the segments with relevant demographic and behavioral variables. In addition, this study makes a longitudinal comparison of these segments in two waves (2009 and 2017) and examines any meaningful changes that occurred during the periods.FindingsSix distinctive lifestyle segments of elderly Koreans are identified. The longitudinal comparison reveals some changes that occurred during the period. The level of importance of values and things to own has been declined during the period on most of the aspects, which can be interpreted that older Koreans become more realistic and practical. The level of life satisfaction between the two periods turned out to be similar. However, satisfaction in material comfort and health has been improved during the period, which means that the perception of their financial and physical aspects has been improved over the years.Originality/valueFirst, based on Tempest et al.’s three grey discontinuity framework (2002), the segmentation model provides comprehensive coverage of psychological transitions experienced by older people due to economic, physical and mental discontinuities with age. Second, this might be the first longitudinal study to examine the changes in segmentation over time in terms of the lifestyle of older adults. Practically, the findings of this study provide useful insights for policymakers in developing aging-related policies as well as for marketers who are interested or currently doing business in Korea or Asian consumer markets.

Association between long-term exposure to particulate matter and childhood cancer: A retrospective cohort study

BackgroundAlthough particulate matter is a known carcinogen, its association with childhood cancer is inconclusive. The present study aimed to examine the association between long-term exposure to particulate matter and childhood cancer. MethodsA retrospective cohort was constructed from the claims database of the Korea National Health Insurance Service, including children born in seven metropolitan cities in Korea between 2002 and 2012. Monthly mean concentrations of particulate matter with aerodynamic diameter <10 μm (PM10) and other air pollutants (NO2, SO2, CO, and O3) were calculated using data from the AirKorea. Monthly mean concentrations of particulate matter with aerodynamic diameter <2.5 μm (PM2.5) were estimated based on a data fusion approach. Cumulative exposure was assessed by averaging the monthly concentrations accounting for the residential mobility of the children. The occurrence of cancer was identified by the appearance of diagnosis codes in the claims database. Hazard ratios (HR) and 95% confidence intervals (95% CI) were calculated using Cox proportional regression, adjusting for potential confounders and O3 concentrations. ResultsDuring the study period, 1,725 patients were newly diagnosed with cancer among 1,261,855 children. HR of all cancers per 10 μg/m3 increment in annual mean concentrations of PM2.5 and PM10 were 3.02 (95% CI: 1.63, 5.59) and 1.04 (0.74, 1.45), respectively. ConclusionPM2.5 exposure was positively associated with childhood cancer in a large retrospective cohort with exposure assessment accounting for residential mobility.

Comparison of natural white clay and acid‐activated white clay for removal of Cd(II) ion from aqueous solution

AbstractNatural white clay obtained from Pohang city in Korea was treated with 6 M H2SO4 and heated at 90 °C for 8 h. The generated clay, called as acid‐activated white clay in this study, was employed as an adsorbent for the removal of Cd2+ in aqueous solution. It was found that the specific surface area and the pore volume of acid‐activated white clay were enhanced when compared with those of natural white clay. The adsorption rate of acid‐activated white clay toward Cd2+ occurred steeply at initial contact time and reached equilibrium within 0.5 h. The amount of Cd2+ adsorbed at equilibrium reduced from 94.2% to 37.94% by increasing initial Cd2+ concentrations from 10 mg L−1 to 100 mg L−1, whereas the amount of Cd2+ increased from 13.54% to 93.38% as adsorbent dose increases from 0.1 g to 1.0 g. The adsorption data of Cd2+ by acid‐activated white clay were introduced to pseudo‐first‐order and pseudo‐second‐order kinetics, and Freundlich and Langmuir adsorption isotherms, respectively. It was seen that the pseudo‐second‐order kinetics and the Langmuir isotherms were applied well to describe the adsorption behavior of acid‐activated white clay toward Cd2+ due to their higher correlation coefficient R2. The maximum adsorption capacities of Langmuir, Q, for natural white clay and acid‐activated white clay were found to be 17.15 mg g−1 and 36.48 mg g−1, respectively. The results of study suggest that acid‐activated white clay can be used as an efficient and low‐cost material for the removal of Cd2+ from wastewater.

Using the City Biodiversity Index as a Method to Protect Biodiversity in Korean Cities

This study calculated the ecological network index (City Biodiversity Index 2) of 85 cities in Korea using the Land Cover Map. Based on the values of the index, four types of city were studied, including Miryang (Cluster A), Anseong (Cluster B), Samcheok (Cluster Cluster), and Yongin (Cluster D). Based on the current status of land use and natural green space in urban areas, small and medium-sized cities do not show many disconnected factors and have a positive (+) effect on the ecological network index (ENI) value. In order to promote urban biodiversity, it is necessary not only to expand the green area quantitatively, but also to improve the quality, such as expanding and connecting natural green areas, and reducing linear disconnection factors.

Sustainable Smart Cities and Industrial Ecosystem: Structural and Relational Changes of the Smart City Industries in Korea

This paper examines the changing industrial ecosystem of smart cities in Korea using both input–output and structural path analysis from 1960 to 2015. The industry type of the input–output tables used in the Bank of Korea was reclassified into nine categories: Agriculture and Mining, Traditional Manufacturing, IT Manufacturing, Construction, Energy, IT Services, Knowledge Services, Traditional Services and other unclassified. The paper identified the changing patterns of an industrial ecosystem of smart cities in Korea. The study found that smart industries such as smart buildings and smart vehicles are anchor industries in Korean smart cities, and they are positively correlated with three other industries: IT Manufacturing, IT Services and Knowledge Services. The results of the input–output and structural path analysis show that the conventional industrial structure of labor-intensive manufacturing and diesel and petroleum cars has been transformed to the emerging high-tech industries and services in smart cities. Smart industries such as IT Manufacturing, IT Services and Knowledge Services have led to sustainable national economic growth, with greater value-added than other industries. The underlying demand for smart industries in Korea is rapidly growing, suggesting that other industries will seek further informatization, automatization and smartification. Consequently, smart industries are emerging as anchor industries which create value chains of new industries, serving as accelerators or incubators, for the development of other industries.

Nursing Students' Acceptance Intention of a Smart Device, Information Literacy, and Problem-Solving Confidence.

The purpose of this study was to investigate the relationship between nursing students’ acceptance intention of a smart device, information literacy, and problem-solving confidence to explore the factors that may improve nursing students’ problem-solving confidence. Data were collected from 450 nursing students between July and August 2019 in two cities in Korea. The results showed that there is a positive correlation between problem-solving confidence and acceptance intention (r = 0.353, p < 0.001) and between problem-solving confidence and information literacy (r = 0.501, p < 0.001). Further, participants with high acceptance intention of a smart device and information literacy scores had significantly higher problem-solving confidence (t = 5.447, p < 0.001; t = 10.072, p < 0.001) than participants with low acceptance intention. In addition, in the logistic regression the odds ratio between the acceptance intention of a smart device, information literacy, and problem-solving confidence groups was odds ratio 2.071 (p < 0.001, CI: 1.412–3.037) and odd ratio 4.966 (p < 0.001, CI: 3.298–7.477). To improve nursing students’ problem-solving confidence, educational strategies should be developed to build information experience and information utilization capabilities.

Diurnal Temperature Ranges in Relation to Lower Limb Amputation Rate of Diabetic Foot in South Korea: A Population Based Nationwide Study.

The evidence for the association between diurnal temperature range (DTR) and diabetic foot amputations is limited. We aimed to investigate the region-specific association between DTR and the amputation rate of diabetic foot in Korean national-wide data. Daily data on DTR and the rate of diabetic foot amputations from 16 provincial capital cities in Korea were obtained (2011–2018). In this study, the latitude ranged from 33°11′ N to 38°61′ N, and we classified each region according to latitude. Region 1, which was located at a relatively high latitude, included Seoul, Incheon, Gyeonggi-do, and Gangwon-do. Region 2, which was located at a relatively low latitude, included Busan, Ulsan, Gyeonsannam-do, Gwangju, Jeollanam-do, Jeollabuk-do, and Jeju-do. The region-specific DTR effects on the amputation rate were estimated based on a quasi-Poisson generalized linear model, combined with a distributed lag non-linear model based on the self-controlled case series design. The DTR impacts were generally limited to a period of nine days, while significant effects during lag days 7–14 were only found in the cities of Seoul, Incheon, and Gyeonggi-do (10th lag day: RR [95% CI]; Seoul: 1.015, [1.001–1.029]; Incheon: 1.052 [1.006–1.101]; Gyeonggi-do: 1.018 [1.002–1.034]). In the subgroup analysis (according to the latitude), an increase of 1 °C in DTR was associated with the risk of diabetic foot in relatively high latitude regions. DTR has considerable effects on the risk of diabetic foot amputation in various provinces in Korea, and it was particularly affected by latitude. The results can inform the decisions on developing programs to protect vulnerable subpopulations from adverse impacts.

The effects of achievement attribution and career indecision on perceived overqualification

In the current study, we aimed to investigate the effect of job applicants’ achievement attribution(luck and effort) on their perceived overqualification(POQ) after employment. We examined the mediating role of career indecision in the causal relationship between achievement attribution and POQ and tested whether major commitment moderated the relationship between achievement attribution and career indecision. A total of 2,747 students participated in the longitudinal survey that was conducted across 20 universities located in different cities of Korea. Approximately a year after the participants reported their achievement attribution, major commitment, and career indecision, researchers contacted those who are employed, and 453 out of 2,747 participated in the follow-up survey and asked to report their POQ. The results showed significant correlations among luck attribution, effort attribution, career indecision, and POQ. Second, although career indecision fully mediated the negative relationship between luck attribution and POQ, it failed to mediate the positive relationship between effort attribution and POQ. Third, major commitment moderated the relationship between achievement attribution(both luck and effort) and POQ. Finally, the conditional effect of luck attribution on POQ was supported as hypothesized. More specifically, luck attribution affected POQ through career indecision while major commitment moderated the negative relationship between luck attribution and career indecision. Discussions on implications and limitations are provided.

Secular Trend of Twin Birth Rate in Metropolitan Cities of Korea, 2000-2019

Objectives: To analyze the seven metropolitan cities of twin birth rate per 100 births (TBR) from 2000 to 2019 in Korea.Methods: We used the 2000-2019 birth certificated data (3,949,097 births) of seven metropolitan cities from Statistics Korea. The data of extra-marital birth and information missing cases (maternal and paternal age and triplet birth) were excluded. The odds ratio and 95% confidence intervals were calculated using logistic regression to describe the regional variance of TBR adjusted for maternal age, age difference between couple and maternal educational backgrounds.Results: During this period (2000-2019 years), the highest TBR by region was observed in Ulsan and Seoul metropolitan city (3.0), and the lowest TBR in Deagu metropolitan city (2.6). The TBR increased by 275 percent from 1.74 in 2000 to 4.79 in 2019. During the period from 2000-2004 to 2015-2019, there was the highest increment of TBR in Ulsan metropolitan city (odds ratio: 1.78; 95% confidence interval: 1.64-1.92) and Busan metropolitan city (1.74; 1.65-1.83), and the lowest increment in Daegu metropolitan city (1.24; 1.17-1.31), after adjustment by logistic regression for demographic variables. During the period 2015-2019 years, there was a significant increase the odds ratio of TBR in Ulsan metropolitan city (1.39), Busan metropolitan city (1.33), Seoul metropolitan city (1.25) and Incheon metropolitan city (1.23), as compared with the TBR of Deagu metropolitan city.Conclusions: Over the past two decades, TBR have risen dramatically in metropolitan cities of Korea. Regional variance of TBR was observed among metropolitan cities in Korea. There is a need for more research to understand the socio-demographic and medical factors associated with regional differences. The national birth registration system needs to be reformed to monitor whether twin births are spontaneous or assisted pregnancy.

Consumer Search and Price Dispersion: A Comparison of Gas Station Prices Before and After COVID-19

탐색이론모형은 동질적인 재화에 대해 두 개 혹은 그 이상의 가격이 존재하는 가격분산을 소비자의 가격탐색에 따른 편익과 비용으로 설명한다. 우리나라 주유소에서 판매되는 운송용 유류는 품질과 서비스의 높은 동질성에도 불구하고 동일한 지역 내에서 다양한 가격에 판매되고 있다. 본 연구는 코로나19가 보통휘발유와 경유의 가격분산 변화에 미친 영향을 실증적으로 분석하고자 한다. 탐색이론모형에 따르면, 코로나19의 확산으로 감염 위험이 증가하여 운전자의 유류소비가 감소하거나 소비자의 가격탐색에 따른 편익이 감소하여 보통휘발유와 경유 소매가격의 분산이 증가할 것이라고 추론할 수 있다. 2019~2020년 서울특별시와 6대 광역시 주유소의 일별보통휘발유와 경유 가격 자료를 패널 고정효과 모형을 이용해 분석한 결과에 따르면, 코로나19 이후 보통휘발유와 경유 가격의 도시 수준 분산이 약 16.5%와 23.4% 증가하였다. 또한 코로나19 누적 확진자수가 증가할수록 보통휘발유와 경유 가격의 도시 내 격차는 확대되었으며, 이러한 효과는 코로나19 확산 초기 누적 확진자수가 적을수록 크게 나타났다. 한편 다른 조건이 일정할 경우, 유류 가격상승 지속기간이 증가할수록 해당 유류의 가격분산은 감소하였지만 가격하락 지속기간은 가격분산에 유의미한 영향을 주지 않았다.The search-theoretic model attibutes the price dispersion, variation in prices across sellers of the homogeneous goods, to the differences in benefits and costs of consumer search for lower price. Transportation oil at gas stations in Korea is sold at various prices even within the same region despite its homogeneity in quality and services. This study analyzed the effect of Covid-19 on the price dispersion of regular gasoline and diesel. According to the search-theoretic model, the spread of Corona 19 is expected to increase the risk of infection such that reduced transportation oil consumption or lowered benefits of price search will result in an increase in the dispersion of regular gasoline and diesel prices. Using daily regular gasoline and diesel price data at Seoul and six metropolitan cities in Korea between 2019 and 2020. we find that the city-level dispersion of regualar gasoline and diesel prices increased by about 16.5% and 23.4% after the spread of COVID-19. Our results also suggest that, as the cumulative number of confirmed cases of Corona 19 increases, the price dispersion of regular gasoline or diesel widens, and this effect is shown to be stronger at earlier days of COVID-19 era. Finally the price dispersion of transportation oil decreases more as the duration of oil price rise lasts longer, but the duration of oil price decline has no statistically significant effect on oil price dispersion.

Health Impact Assessment of PM2.5 control legislation in Korea

BACKGROUND AND AIM: Exposure to PM2.5 has been associated with increased all-cause mortality. The metropolitan area particulate matter reduction policy is enacted to reduce PM2.5 concentration in 2008. The policy selected substances subject to particulate matter management, implemented total emission regulations in Seoul and Incheon, strengthened standards for allowing emissions for production vehicles, and promoted reduction of diesel car emissions. The aim of the present analysis is to evaluate the effectiveness of the policy on health. METHODS: The policy was applied to Seoul and Incheon, and other metropolitan cities in Korea were selected as control groups. We conducted interrupted time series analyses to examine changes in PM2.5 concentration and concentration-response function after the enactment of the policy. Based on the calculated change, we estimated the health benefit in terms of reduced mortality. RESULTS:We observed a decrease in the slope of concentration-response function of all-cause mortality after intervention in Seoul and Incheon. PM2.5 concentrations also decreased. The interaction coefficient about intervention was -0.537 (p value=0.001) in Seoul and -0.0276 (p value=0.64) in Incheon. We calculated the number of excess deaths when there was no intervention effect, when only PM2.5 concentrations were decreased, when only concentration-response function was decreased, when both concentration-response function and PM2.5 were reduced. The number of excess death in Seoul was 684.1 (221-1112.3), 654 (230.1-1149.1), 450.9 (0-883.1), and 432.2 (0-919.1), respectively. We observed 137.1 (0-673.4), 113.8 (0-560.7), 82 (0-236.2), and 68.7 (0-196.7), in Incheon, respectively. CONCLUSIONS:The all-cause mortality caused by PM2.5 in Seoul and Incheon decreased after intervention.

Association between long-term exposure to particulate matter and childhood cancer: Retrospective cohort study

BACKGROUND AND AIM: Particulate matter is known carcinogen, but its association with childhood cancer is inconsistent. The aim of the present study was to examine the association between air pollution and childhood cancer. METHODS: A retrospective cohort was constructed from claims database of the Korea National Health Insurance Service. Children who had been born in 7 metropolitan cities in Korea (Seoul, Incheon, Daejeon, Gwangju, Daegu, Busan, and Ulsan) from 2002 to 2012 were recruited and half of them were randomly selected. Children who were diagnosed with cancer within 5 years of birth were excluded. Monthly mean concentrations of particulate matter with aerodynamic diameter 10 μm (PM10) and other air pollutants (NO2, SO2, CO and O3) was calculated from AirKorea. Monthly mean concentrations of particulate matter with aerodynamic diameter 2.5 μm (PM2.5) was estimated with a concentration prediction model. The cumulative exposure was calculated by averaging monthly concentrations according to the subject's residential information. We constructed Cox proportional hazard model adjusting for potential confounders and O3 concentration. RESULTS:A total of 1,261,855 children (boys 641,704, girls 610,151) were included in the analysis. During the study period, 1,725 were newly diagnosed with cancer. Exposures to higher mean ambient PM2.5 and PM10 concentration increased the risk of childhood cancer. The hazard ratio of all cancers was 3.02 (95% confidence interval [CI]: 1.63, 5.59) and 1.04 (95% CI: 0.71, 1.45) for an increment of 10 μg/m3 of annual mean concentrations of PM2.5 and PM10, respectively. CONCLUSIONS:We observed significant positive association between particulate matter exposure and childhood cancer in a retrospective cohort of 1.2 million children. KEYWORDS: Particulate matter, Cancer, Children, Retrospective cohort

Integrating multi-scale inspection, maintenance, rehabilitation, and reconstruction decisions into system-level pavement management systems

We are presenting a pavement management framework that involves multi-scale decisions, including system-level budget allocations, group-level inspections, and facility-level maintenance, rehabilitation, and reconstruction (MR&R) strategies. We consider two objectives: (i) to minimize the total discounted cost for the main stakeholders, represented by the agency and users; and (ii) to minimize the discounted user costs under a limited agency budget. Inspection technology innovations have enabled us to investigate the conditions of a group of multiple roadway facilities almost simultaneously, using instrumented vehicles that can travel at the same speed as traffic. Previous related studies have primarily focused on, at most, a bi-level structure with all the managerial activities, such as inspection and MR&R at the facility level and the allocation of a pooled budget at the system level. However, this cannot reflect the current group-level inspection practice, positioned between the facility and system levels. The proposed methodology adopts a bottom-up approach to account for heterogeneous facility- and group-specific properties, and it optimally facilitates determination of the multi-scale decisions to minimize the discounted societal costs. We address the complex multi-scale problem efficiently by adopting the Markov Decision Process, function approximation, and Lagrangian relaxation. As a numerical study, we analyze a real-world roadway network, including three expressway groups and one local road group, near Daejeon City in Korea. The system-level optimal solutions for the multi-scale decisions are determined, and the impacts of the grouping method are investigated.

A Study on the Relationship between Fatigue, Psychosocial Stress, and Behavior that Reduces Endocrine Disrupting Chemicals Exposure in Infertile Males

Purpose: This study aimed to identify the relationships between fatigue, psychosocial stress, and behavior of infertile males that reduces endocrine-disrupting chemical (EDC) exposure and to provide baseline data needed for nursing intervention. Methods: A total of 110 infertile males were recruited from a special fertility hospital in Gwangju city in Korea. The participants were administered a self-reported questionnaire. Results: The mean scores were as follows: for fatigue, 59.1 out of 133; for psychosocial stress, 20.3 out of 54; and for behavior that reduced EDC exposure, 52.6 out of 85. Fatigue and psychosocial stress had a positive correlation(r=0.68, p&lt;0.001), behavior that reduces EDC exposure was negatively correlated with fatigue and psychosocial stress(r=-0.54, p&lt;0.001; r=-0.61, p&lt;0.001) Conclusion: Fatigue and stress were higher in infertile males. Our findings suggest that a nursing intervention program should focus on reducing fatigue and stress in infertile males and induce behaviors that decrease EDC exposure.

Residents’ Perception of a Collaborative Approach with Artists in Culture-Led Urban Regeneration: A Case Study of the Changdong Art Village in Changwon City in Korea

This study asserts that the higher the degree of artists’ and residents’ participation in a culture-led renewal project, the higher the level of residents’ satisfaction. Engaging artist groups and introducing cultural programs can facilitate building a collaborative network between artists and residents. This paper adopts an experimental study method and defines the experimental and control groups as follows: the experimental group (Changwon city) has relatively high artist participation, and the control group (Sacheon, Gimhae, Miryang cities) have relatively low artist involvement. Multiple regression analysis was conducted utilizing 192 valid survey data in R studio software. The significant variables were compared between the experimental group (Model 1) and the control group (Model 2). As a result, the relative effects of “1. experience (or amount) of residents’ participation in urban renewal programs”, “2. reflection of residents’ opinions”, and “3. neighborly trust” on “residents’ satisfaction with urban regeneration projects and expected outcomes” was shown to be greater in the experimental group. The result implies that the involvement of cultural entities and the operation of arts programs increase residents’ will to participate in renewal projects and to build neighborly trust. Further, collection and reflection of residents’ opinions about the renewal works were more smoothly completed when mediated by artist participation and using cultural content.

Individual and organizational factors influencing workplace cyberbullying of nurses: A cross-sectional study.

Workplace cyberbullying has emerged as a new issue. This study aimed to explore individual and organizational factors that affect nurses' workplace cyberbullying in hospital settings. A multicenter, cross-sectional study was conducted using a self-report questionnaire. Three tertiary and 18 general hospitals were selected from one city in Korea. A total of 270 nurses with 6months to 10 years of experience in the current department were enrolled. Multiple regression analysis was conducted to identify the factors associated with cyberbullying. Workplace cyberbullying was affected by self-labeled victimization due to face-to-face bullying, subjective health level, years of experience as a nurse (β=0.148, p=0.009), and relation-oriented nursing organizational culture. Face-to-face bullying must be addressed to prevent workplace cyberbullying. It is important to assist nurses to maintain good health-considering that, new nurses with less than 1 year of experience are vulnerable to being victimized. Effective prevention strategies should be prepared to control workplace cyberbullying in clinical practice.
