  • This study was conducted to investigate the effects of participation in adult education on cognitive function, and the mediating effects of relationships with children among older adults. This study employed data from the 2011 Elderly Survey, and a total of 8,668 older adults over 65-years old were used for analysis. Multiple linear regression analyses were used to examine the mediating effect of relationship with children based on the approach proposed by Baron & Kenny (1986). The results showed that participation in adult education increased cognitive function of older adults. Adult education participation also increased satisfaction with relationship with children, and relationship with children was found to have a mediating effect. These findings suggest that there is a need to recognize the importance of the relationship between older adults and children when developing education programs for older adults.

  • Objective : The purpose of this study was to examine the level of the cognitive function, and to identify the influencing factors on cognitive function in women cancer patients receiving chemotherapy. This study attempted to provide basic data useful to development of nursing intervention and improve the quality of life in women cancer patients. Methods : As a cross-sectional descriptive study, women with receiving chemotherapy above one cycle were recruited. One hundred and twenty-five women cancer patients who met the study criteria agreed to participate in the study. The questionnaire set consisted of cognitive function, quality of life, depression, anxiety and information on demographic and clinical characteristics. Results : There was no statistically significant difference in clinical characteristics according to the cognitive function. The cognitive function was higher the more low age (F=9.937, p<.001), and the more high education level (F=12.332, p<.001). Multiple regression analysis showed the predictors were significantly related to cognitive function. age, education, and the number of chemotherapy explained 31.8% of the cognitive function. Conclusions : This result of this study provides basic information about factors influencing cognitive function, although study findings are insufficient in explaining related variables among women cancer patients. Even though women cancer patients were receiving chemotherapy, this study showed that the level of cognitive function was high. In order to receive better results and findings the period decreasing cognitive function, further studies are need to measure cognitive function according to the passage of time during or after chemotherapy.

  • The LWR (Locally Weighted Regression) model, which is traditionally a lazy learning model, is designed to obtain the solution of the prediction according to the input variable, the query point, and it is a kind of the regression equation in the short interval obtained as a result of the learning that gives a higher weight value closer to the query point. We study on an incremental ensemble learning approach for LWR, a form of lazy learning and memory-based learning. The proposed incremental ensemble learning method of LWR is to sequentially generate and integrate LWR models over time using a genetic algorithm to obtain a solution of a specific query point. The weaknesses of existing LWR models are that multiple LWR models can be generated based on the indicator function and data sample selection, and the quality of the predictions can also vary depending on this model. However, no research has been conducted to solve the problem of selection or combination of multiple LWR models. In this study, after generating the initial LWR model according to the indicator function and the sample data set, we iterate evolution learning process to obtain the proper indicator function and assess the LWR models applied to the other sample data sets to overcome the data set bias. We adopt Eager learning method to generate and store LWR model gradually when data is generated for all sections. In order to obtain a prediction solution at a specific point in time, an LWR model is generated based on newly generated data within a predetermined interval and then combined with existing LWR models in a section using a genetic algorithm. The proposed method shows better results than the method of selecting multiple LWR models using the simple average method. The results of this study are compared with the predicted results using multiple regression analysis by applying the real data such as the amount of traffic per hour in a specific area and hourly sales of a resting place of the highway, etc.

  • Purpose: This study was a descriptive survey research to identify the impact of bowel function, anxiety and depression on quality of life in patients with rectal cancer who had a sphincter-preserving resection. Methods: Participants were 100 patients who had rectal cancer surgery at W hospital in Korea. Bowel function, anxiety & depression, and quality of life were measured using the BFI (Bowel Function Instrument), HADS (Hospital Anxiety-Depression Scale) and the FACT-C (Functional Assessment of Cancer Therapy-Colorectal). Results: The mean scores were $39.81{\pm}5.16$ for bowel function, $6.15{\pm}3.25$ for anxiety, $7.24{\pm}3.13$ for depression, and $72.50{\pm}13.27$ for quality of life. There were significant negative correlations between quality of life and anxiety (r= -.59, p <.001) and between quality of life and depression (r= -.53, p <.001). But the correlation between quality of life and bowel function was significantly positive (r=.22, p =.025). The influence of the independent variables on the total quality of life was examined using multiple regression analysis. Anxiety (${\beta}$= -.38, p =.002), bowel function (${\beta}$= -.25, p =.028) and occupation (${\beta}$=.16, p =.048) were identified as factors affecting quality of life. The explanation power of this regression model was 44% and it was statistically significant (F=16.53, p <.001). Conclusion: The results of this study indicate that in order to improve the bowel function of patients after sphincter-preserving resection for rectal cancer, effective nursing interventions should be developed. As psychological problem such as anxiety and depression can relate to quality of life for these patients, nurses should work on improving the situation by providing continuous emotional nursing.

  • The aim of this study was to investigate the relationship among family function, intimacy risk with the opposite sex, and campus life satisfaction among college students. A descriptive study was conducted. Data were collected from May 11, 2017 to May 20, 2017 by using a structured questionnaire. The participants were 180 college students at two colleges in J-city. Data were analyzed using t-test, one way ANOVA, Scheffe test, pearson correlation coefficient, and multiple regression analysis with SPSS 20.0. The mean scores were as follows: family function $3.07{\pm}0.44$(5 points), intimacy risk with the opposite sex $2.03{\pm}0.59$(4 points), and campus life satisfaction $3.20{\pm}0.50$(5 points). There was a significant correlation between the family function, intimacy risk with the opposite sex, and campus life satisfaction variables. Multiple regression analysis showed that factors influencing campus life satisfaction were family communication(${\beta}=0.341$, p=.001) and parental economic activity type(${\beta}=0.161$, p=.007). The explanation power of this regression model was 13.1%. These results of this study indicate that effective campus life satisfaction should be developed by including improvement of family community of family function.

  • The purpose of this study was to investigate the relationships among density, moisture content, and modulus of elasticity in which are important characteristics in physical and mechanical properties of woods. In this study, the dynamic MOE was calculated through the combination with resonance frequency of transverse vibration method and density, and the estimated moisture contents were calculated with two different equations (1, 2) in order to compare with experimental moisture contents. The following results from this study were obtained: 1. According to the regression analysis with two different parameters (E and density), the two regression lines appeared to be straight intersecting at 0.6 density. As another factor, moisture contents in wood also influenced on the analysing regression at the below F.S.P. 2. When considering the relationship between moisture contents and E, the tendency of each moisture content and E showed very similar pattern suggesting that moisture contents in addition to density are very important parameter. 3. When together with moisture contents and density as parameters for multiple regression analysis, coefficiences of determinations are dramatically improved. Interestingly, the coefficiences of determinations are further increased when analysing at the below point of F.S.P. and when analysing higher and lower density separately. In summary, more correct estimation of the dynamic MOE of woods can be possible with only transverse vibration and density in wood. Therefore, with this indirect method, the calculation of MOE in all kinds of woods including timber, live tree and wood products can be feasible resulting in accelerating the efficiency of time and labor.

  • This study examined the sexual function, sexual distress, and quality of life of middle-aged women with osteoarthritis, as well as the factors influencing the quality of life. The participants were 121 middle-aged women who have been suffering osteoarthritis. Data collection was conducted from September 1 to October 31, 2019. The instruments were the Female Sexual Distress Scale (FSDS), the Female Sexual Function Index (FSFI), and the World Health Organization Quality of Life Assessment Instrument (WHOQLO) -BREF scale. Data were collected with structured questionnaires and analyzed using a t-test, ANOVA, Pearson's correlation analysis, and multiple regression analysis. A positive correlation was observed between sexual function and quality of life, whereas sexual distress had a negative correlation between sexual function and the quality of life. Factors affecting the quality of life of middle-aged women with osteoarthritis were sexual function, sexual distress, which explained 16.1%. Sexual distress, sexual function, and quality of life showed a correlation. Therefore, it is important to develop a nursing intervention that can improve the sexual function and reduce the sexual distress of middle-aged women with osteoarthritis to improve their quality of life.
