  • This study has performed comparative analysis on characteristics of contaminated 35 tributaries on seasonal variation/point discharge load/pollutant distribution of water quality factors(8) in order to understand the effect of the watershed in Nakdong River Basin. As a results, the water quality of $BOD_5$(Biochemical Oxygen Demand), Chl-a(Chlorophyll a) and Fecal E. Coli shows II grade at tributaries of more than 50% without COD(Chemical Oxygen Demand), TP(Total Phosphate), TOC(Total Oxygen Carbon) and TN(Total Nitrogen) factors. The specific discharge(Q) were occupied about 54.4% (19 sites) as $0.05m^3/sec/km^2$ value. Among these results, the contaminant level of Dalseocheon, Hyeonjicheon, Seokkyocheon 1, Uriyeongcheon and Dasancheon was also high, which has to consider a discharged pollutant load(kg/day). The 35 major tributaries of Nakdong River were included in 7 mid-watershed, such as Nakdong Waegwan, Geumho River, Nakdong Goryung, Nakdong Changnyung, Nam River, Nakdong Milyang, Nakdong River Hagueon. Especially, the discharged pollutant load of Nam River and Geumho River also was high according to the amount of discharge such as Kachang dam, Gongsan dam and Nam river dam. Seasonal difference of the water quality factors such as $BOD_5$, TN, SS and Q was observed largely, on the other hand the TP and Chl-a was not. This is guessed due to the precipitation effect of site, biological and physicochemical degradation properties of pollutant and etc. The co-relationship between the seasonal difference and water quality factors was observed using a Pearson correlation coefficients. Besides, the Multiple Regression analysis using a Stepwise Regression method was conducted to understand the effect between seasonal difference and water quality factors/regression equations. As a result, the Multiple Regression analysis was adapted in the spring, summer and autumn without the winter, which was observed high at spring, summer and autumn in the order COD/TP, Chl-a/TOC, TOC/COD/$BOD_5$ water quality factors, respectively.

  • Purpose: This study aims to identify factors that influence middle-aged men's attitude towards death. Methods: The study enrolled 204 middle-aged (range=40~59 years) male residents of Daegu in Korea. Using a structured questionnaire, data were collected in October 4~30, 2010. For data analysis, we used descriptive statistics, t-test, one-way ANOVA, Scheff$\grave{e}$'s test, Pearson correlation coefficient, and stepwise multiple regression with SPSS WIN 14.0. Results: Participants' attitude towards death significantly differed according to educational level, religion, volunteer activities, and perceived health status. Moreover, their attitude towards death was negatively correlated with life stress and depression and positively correlated with self-esteem, life satisfaction, and coping behavior. The factors influencing the attitude towards death were life satisfaction, daily stress, religion, and depression, which explained approximately 25.7% of the total variance. Conclusion: Middle-aged men perform a crucial role in our society, and their attitude toward death affects how they cope with a situational crisis such as a terminal cancer or withdrawal of life sustaining treatment. Therefore, it is necessary to develop and implement a support program for middle-aged men, which offers them with various strategies to better manage their daily stress and improve their life satisfaction and coping skills.

  • This study analyzed the impact of venture companies' innovation capabilities on business performance by growth stage. Innovation capability, which is an independent variable, is composed of entrepreneur characteristics, technology development capabilities, marketing capabilities, and external cooperation. And the dependent variables were set as sales and long-term growth prospects. This study utilized data from the '2022 Precise Survey on Venture Companies'and conducted descriptive statistics analysis, correlation analysis, and multiple regression analysis as research methodology. As a result of the analysis, the negative influence of the educational background of entrepreneurs' characteristics was found to decrease as the growth stage increased, and the long-term growth prospects of entrepreneurs with abundant industrial practical experience were perceived positively. Research and development personnel was a negative factor during the start-up period, but as the growth stage increased and technology accumulation occurred, it changed into a positive factor. Marketing competency level was found to be an important factor in all growth stages. For external collaboration activities, all hypotheses regarding sales were rejected, but hypotheses regarding the start-up and growth periods regarding long-term growth prospects were accepted. it is interpreted that external collaboration activities are necessary to overcome the limitations of internal resources.

  • This study investigated any possible financial attributes of the CDS spreads of a firm belonging to financial industries headquartered in the Republic of Korea. There were few studies on this issue, especially for the firms located in emerging capital markets. Coupled with the models such as a multiple regression and a principal component analysis(PCA), this research has identified that only two explanatory variables such as SLOPE and INTER3 (i.e. interaction effect between the BETA and the SLOPE) consistently showed their statistically significant influence on the CDS spreads through the 'selected' model without and with applying a stepwise regression procedure for the robustness. Given the rapid developments of sophisticated financial derivatives, this study may suggest a valuable insight to foreign and domestic investors to identify the possible determinants of CDS spreads at the firm- and/or the industry-level.

  • This study aimed to investigate pain, perceived exercise barriers, and related factors in arthritis patients. The study was conducted on 140 arthritis patients (89 rheumatoid arthritis patients and 51 osteoarthritis patients) who visited C University Hospital in Daejeon due to arthritis and agreed to participate in a survey. The self-administered survey was conducted from February 2011 to September 2011. The results are as follow. The perceived exercise barriers increased in both groups as the education level and monthly household income decreased. In the rheumatoid arthritis group, the pain became more intense as the self-rated health status became poorer while the perceived exercise barriers became more significant as the self-rated health status became poorer and the patients had other diseases besides arthritis. In the osteoarthritis group, the pain was greater as the duration of arthritis was longer and the self-rated health status became poorer. In both groups, the perceived exercise barriers became more significant as the exercise stage approached the pre-planning stage. The results of the multiple linear regression analysis showed that the most influential factor on pain in both groups was the 'very bad' self-rated health status. In the rheumatoid arthritis group, influential factors on the perceived exercise barriers were the exercise stage and the education level while for the osteoarthritis group, they were the exercise stage and the monthly household income. In conclusion, the results of this study showed that the pain and perceived exercise barriers of arthritis patients were associated with various factors such as the education level, monthly household income, self-rated health status, and exercise stage, which suggests that these factors should be considered in the planning of exercise programs.
