  • The ecosystem in the Gwangju Stream has taken a wide range of disturbance such as the discharging water of sewage treatment plant, the lake water and the river water from different water system over the past decade. This study was figured out some significant influence factors by analyzing the relationship between biotic and abiotic factors in the urban stream. Abiotic components included 15 water quality variables which were measured in five sampling sites along the stream from October 2014 to July 2015, whereas the benthic macroinvertebrates found in those sites were used to estimate various biotic indices representing the ecological status of the community. The results of correlation analyses indicated that abiotic factors by human activities affected on the inhabitation of benthic macroinvertebrates more than biotic factors. The results of cluster analyses and ANOVA tests also showed that biotic and abiotic characteristics were clearly different in season. The main influence factors of cluster analysis by sites were $NH_3-N$, EPT(I) and DO. It was considered that more various statistical analyses would be necessary to find some different relationships and influence factors between biotic and abiotic variables in the urban stream.

  • Purpose: This study was conducted to estimate the prevalence of questionable development according to developmental screening testing for children, and to explore biological and environmental risk factors of developmental delays. Method: The study participants were 153 children under two years of age. A questionnaire and Home Observation for measurement of the Environment (HOME) inventory were used to collect data, and Korean Denver II was administered. Results: The overall prevalence of questionable development was 11.1%. Significant differences in biological factors between the normal development group and questionable development group were the rate of prematurity, twins, the educational level of mother and father's and the presence of an illness in the mother (p<.10). Maternal acceptance in HOME was significantly different between the two groups. The factors related to questionable development that were significant in the logistic regression analysis were prematurity (OR=3.56, p=.026), and maternal acceptance in HOME score (OR=.629, p=.028). Conclusion: Early developmental screening tests seem necessary for all children, especially for prematurely born children. Also, child rearing environments were identified as significant factors in the development of all children. These findings suggest that the HOME scores might be useful in identifying children at risk for developmental delays, and that interventions for these children will probably be more effective if their mothers are helped to provide a more appropriate social environment.

  • Objective: The aim of this study is to investigate the effect of workload on musculoskeletal degeneration. Background: It is important that workers maintain a health body for a long time as a measure of aging workers. In order do so, it is necessary to find out if workload can effect on musculoskeletal degeneration. Method: Epidemiological studies on workload or occupation and disc degeneration, osteoarthritis of knee were identified through database and bibliography searches. Results: Epidemiological studies showed that workload certainly effect on musculoskeletal degeneration. But we couldn't know which of individual factors and occupational factors further contribute to the musculoskeletal degeneration. And we could find that studies on workload and genetic factors were very few. In addition, there was also very few studies that it was possible interaction between individual factors as obesity and occupational factors as heavy manual lifting. Conclusion: Our reviews suggest that it need to conduct study between workload and genetic factors for musculoskeletal degeneration. This further study can identify attributable risk of workload for musculoskeletal degeneration, and contribute to the measure of aging workers. Application: This paper can help to establish research plan for the measure of aging workers.

  • Objective: The purpose of this study was to analyze the risk factors of MSDs for the types of office work. Background: Physical risk factors of VDT(Video Display Terminal) associated with shoulder and neck musculoskeletal disorders(MSDs) include static work postures and workstation status. Method: In this study, office work was divided into data search, data entry and design work(drawings, etc.), and then we were surveyed 7 major work places which was included these works. We recorded working postures and obtained still images, depending on the types of office work. Then, RULA(Rapid Upper Limb Assessment) and ROSA(Rapid Office Strain Assessment) were used to analysis the risk factors. Results: The results of RULA showed that design work was under risk levels and required change, but ROSA showed that data entry and design work were high risk. The RULA is to evaluate the level of risk factors based on the working posture; on the other hand, the ROSA is to consider the use of peripheral, same as chair, keyboard/mouse, monitor and computer workstations. Conclusion: Conclusions of this study, the office work is necessary to identify the risk factors caused by the use of peripheral, as well as working posture.

  • This study is intended to identify critical success factors(CSF) of real-time enterprises(RTE) by using a policy leverage method of system dynamics. Since RTE is a new theoretical system that unifies existing theories or concepts in business management and information technology, it is not proper to employee a traditional statistical method. To obtain our research goal, causal maps of system dynamics are employed to abstract and arrange RTE information from previous studies. By using the commonness of policy leverage and critical success factors, CSFs for the RTE are deduced by substituting the leverage points on causal maps with necessary success factors to solve the problems. Since this is a new approach to identify success factors. it has some restrictions. Unlike the statistical methods, this approach explains only the directions of causalities and correlations. For the future research, a simulation tool of system dynamics can be employed to discover how each CSF is correlated to the successful implementation of RTE.

  • Purpose: The purpose of this study was to investigate the factors impacting the posttraumatic growth (PTG) factors during chemotherapy in gynecologic oncology patients. Method: The data were collected at six hospitals at a university hospital, general hospital, women's hospital, and 3 oncology hospitals in D metropolitan city. The participants of the study were 135 female patients undergoing chemotherapy for their gynecologic oncology. To identify the factors that influence PTG, we used the questionnaires for the family support, sexual distress, health promoting behavior, and PTG. Results: There was a significant positive correlation between family support and health promoting behavior and PTG. There was significant negative correlation between sexual distress and PTG. Factors impacting the PTG of gynecologic oncology women undergoing chemotherapy were age, recurrence, family support, sexual distress, and health promoting behavior. These factors accounted for 47.0% of PTG. Conclusion: It is necessary to develop and apply programs that include sexual distress management education, and health promotion with families. PTG programs for gynecologic oncology patients undergoing chemotherapy should be approached considering these results.

  • This study analyzes the effects of trade globalization and financial globalization on consumption classified by type(durable, quasi-durable, non-durable and service). On the other hand, trade globalization and financial globalization were decomposed into OECD common factor, regional factors, and the idiosyncratic country-specific factors by time-varying dynamic factor analysis. The characteristics of OECD common factor, regional factors, and the idiosyncratic country-specific factors of trade and financial globalization were analyzed. Furthermore, the influences of these factors on consumption by type were analyzed. The analysis shows that globalization has negative effects on consumption. In particular, we found out that the idiosyncratic country-specific factor of Korea in trade and financial globalization had a statistically significant negative effect on consumption. We can infer that the globalization affecting consumption can be attributed to the idiosyncratic country-specific factor, which is economic choice rather than uncontrollable global trend. Accordingly, to solve the sluggish consumption problem caused by globalization, it is necessary to require not only domestic consumption expansion policies but also the efforts to resolve economic polarization problems to be able to stimulate consumption.

  • Purpose: This study aimed to investigate the risk factors for cardiac implantable electronic device (CIED)-related infections within the first post-procedural year after CIED insertion. Methods: This study included 509 adult patients undergoing CIED implantation procedures between January 1, 2011 and December 31, 2015. The data were analyzed by t-test, chi-square test, Fisher's exact test, and logistic regression analysis using SPSS/WIN 23.0. Results: Fifteen infections and 494 non-infections were examined. The CIED-related infection rate was 2.9%; patients with 14 pocket infections and one bacteremia were included in the CIED-related infection. The risk factors of CIED-related infections were the estimated glomerular filtration rate (eGFR) of ≤ 45 mL/min/1.73 m2 (Odds ratio [OR]= 4.03, 95% confidence interval [CI],1.15-14.10) and taking a new oral anticoagulant (NOAC) (OR = 4.50, 95% CI 1.09-18.55). Conclusion: These results identified the CIED infection rate and risk factors of CIED-related infection. It is necessary to consider these risk factors before the CIED implantation procedure and to establish the relevant nursing interventions.

  • Purpose: Due to the COVID-19 and inflation, participation sports companies, including fitness centers, are facing challenges. Since a fitness center must simultaneously manage facilities and operate services, both factors must be considered when developing a marketing strategy. Therefore, this study examines the effects of expanded marketing mix factors (price, physical evidence, place, people, product, and promotion) including facilities and services on the consumption behavior (satisfaction, recommendation intention, repurchase intention) of fitness center customers. Research design, data, and methodology: The data were collected from sample of 323 fitness club members in Seoul and analyzed with SPSS Win Ver.28.0 program. Result: The specific results of the study were as follows; First, extended marketing mix factors had significant positive (+) effect on satisfaction. Second, extended marketing mix factors had significant positive (+) effect on recommendation intention. Third, extended marketing mix factors had significant positive (+) effect on repurchase intention. Fourth, satisfaction had significant positive (+) effect on recommendation intention and repurchase intention. Conclusions: To encourage consumption behavior, it is necessary to convert existing customers into loyal ones by increasing satisfaction and establishing a virtuous cycle structure that recommends them to others while also improving repurchase intention.
