Purpose: This study is to identify how the meaning in life, depression, and social support influences the suicidal ideation of old adult hemodialysis patients. Methods: A cross-sectional design was used. A descriptive correlative study was conducted through an organized and structured self-administrated questionnaire survey for 120 sampled old adult renal dialysis patients. The collected data were analyzed by t-tests, ANOVA, Pearson's correlation coefficient, and multiple linear regression analysis using the Stata 13.0 program. Results: The suicidal ideation of participants was positively correlated with the meaning in life, and social support, and the depression was negatively correlated with the suicidal ideation. Significant factors influencing the suicidal ideation included the meaning in life, depression, social support, age, caregiver, monthly income, and smoking. These factors explained 68% of the variance. Conclusion: The depression of old adult hemodialysis patients was a major risk factor that increased suicidal ideation, and the meaning in life and social support was a protective factor that reduced the suicidal ideation. These results suggest that health professionals should provide old adult hemodialysis patients with proper management of suicidal ideation, and depression as well as its meaning in life, and social support.

This study aimed to investigate resource transfer for baby boomers' adult children and related factors pertaining to baby boomers' later-life preparation. This study was conducted in 2016 using written questionnaires completed by 405 baby boomers residing in Seoul and metropolitan cities in South Korea. The data were analyzed using IBM SPSS Statistics 23.0 and the following statistical methods: frequency, percentiles, the mean, standard deviation, a t-test, one-way ANOVA, Cronbach's alpha, and hierarchical multiple linear regression analysis. Baby boomers' average level of later-life preparation was found to be 3.45/5, a relatively rational score. Baby boomers tended to transfer more resource from their adult children when they had many adult children, were more satisfied with their romantic relationship. Baby boomers' level of later-life preparation was higher when there was lesser resource transfer of their adult children. The greatest influential variables pertaining to the respondents' later-life preparation were their family's income, children's marital status, satisfaction with their romantic relationship, and level of transfer from their adult children. It was concluded that baby boomers have insufficient later-life preparation in terms of finances due to their need to support their adult children; thus, nation-wide practical programs are needed to prepare baby boomers for a happy life.

The present study is to investigate the elements of e-learning strategies affecting the levels of participation, achievement and satisfaction for learners who participated in the university blended learning environment. For this, 58 subjects were recruited who participated in the blended learning class at K university. E-learning strategies, achievement and satisfaction levels were measured for data collection, and the level of participation was measured by analyzing the LMS log-in database. For data analysis, first, means and standard deviation were computed to find the level of e-learning strategies of the subjects. Second, linear regression analysis was conducted to find the e-learning strategies that could estimate the levels of achievement, participation and satisfaction. As a result, variables to estimate the achievement level included time management strategy and overload management strategy. Variables to estimate the participation level included self-directed strategy, time management strategy and overload management strategy. Finally, variables to estimate the satisfaction level included multiple discussion management strategy, asynchronous management strategy and sociality. Based on these estimated variables, the author suggested some ideas to increase the educational effectiveness.

We studied in order to find out suitable amounts of board by visual effects to establish indoor boards and human psychological effects by several board designs. Thirty students of C university were tested in constant temperature/humidity room and interviewed after tests. The experimental visual images were projected from 54' TV. As a result, the board length that showed high preference and satisfaction was the 90cm both horizontal and vertical direction. We found that vertical board gave an impression of a linear and narrow shape and the horizontal board gave wide space and cool feeling from psychological analytical study. The factors affecting satisfaction in horizontal direction were refreshing, intimacy, beauty, area, splendor and those in vertical direction were a sense of security, beauty, texture, intimacy, continuity, extensity, natural feeling. We got 5 factors from the result of factor analysis in order to get psychological factor axis. Those were pleasantness, artificiality, openness, dynamics, refinement. By multiple regression analysis, the factor pleasantness had the highest impact on visual satisfaction on scenary. The study on psychological factor difference by analysis of variance showed that psychologically feeling amount about pleasantness, artificiality, dynamics, refinement, and openness had statistically meaningful difference despite of board direction. We found that the 90cm had a tendency as a changing point leading image change by the investigative analysis of board direction based on factor points.

Objectives: This study aims to identify the impact of subjectively reported oral health status on the quality of life by applying the PRECEDE model. Methods: This study was conducted on a total of 450 people who had dental visit experience among persons above 35 and under 65 years living in Seoul and Gyeonggi provinces. Oral health-related quality of life was measured using the OHIP-14. The relationship between subjectively reported oral health status and the quality of life was evaluated by the chi-square test, t-test, one-way ANOVA and multiple linear regression analysis. Results: OHIP-14 scores were significantly associated with self-reported oral health problem. Especially the strongest correlations were found between functional limitation, physical psychological social disability on the OHIP-14 7 sub-factor and self-reported periodontitis and dry mouth symptoms. Conclusion: Subjectively reported oral health status is associated with oral heath related quality of life. In order to improve people's the quality of life, taking care of their oral heath is indispensable factor. Therefore, it is required to revitalize regular oral health check system and the development of effective oral health education programs by the government to prevent periodontitis and dry mouth as well.

Purpose: The aims of this study were to examine the work, client, and personal environments of community health practitioners, including the level of their professional quality of life (ProQOL), and identify the factors affecting their ProQOL. Methods: Data were collected using a web-survey questionnaire, which was completed by a sample of 308 community health practitioners currently working in Korea. The questionnaire included items on ProQOL; three dimensions labeled compassion satisfaction, burn out, and secondary traumatic stress; job stress; job satisfaction; sense of community; and general characteristics. Results: The mean scores for the three dimensions were $39.2{\pm}6.44$ (compassion satisfaction), $31.9{\pm}3.59$ (burn out), and $26.4{\pm}5.05$ (secondary traumatic stress). A multiple linear regression revealed that compassion satisfaction varied significantly according to the satisfaction with job choice, sense of community, job stress, and job satisfaction. The factors affecting burn out were sense of community and work load, while the factors affecting secondary traumatic stress were education, job stress, and job satisfaction. Conclusion: The findings of this study suggest that comprehensive intervention focusing on improving the sense of community and job satisfaction and reducing job stress is essential to promote community health practitioners' ProQOL.

The purpose of this study was to explore the effects of adolescent consumers' attitudes toward money and conspicuous consumption on unethical consumption behavior in commercial transactions. The main survey was conducted targeting 290 middle and high school students. As a result of this research, first in the case of adolescent's attitudes toward money, the symbol for happiness and success was 3.11 and the means of control was 1.77 respectively. The level of conspicuous consumption behavior was 2.75 and the level of unethical consumption behavior scored as passive unethical consumption behavior was 1.38 while the active unethical consumption behavior was 2.10. Second, in the case of the attitude toward money as a means of control, it differentiated according to the level of living and the amount of allowance. Conspicuous consumption behavior differentiated according to the amount of allowance and the father's education. Active unethical consumption behavior showed a difference according to the amount of allowance and the father's education. Multiple linear regression analysis conducted to identify relative effects of the variables that affect unethical consumption behavior, in case of passive unethical consumption behavior, showed that conspicuous consumption(${\beta}$=.23, p<.01) and attitudes toward money as a means of control(${\beta}$=.29, p<.001) with an explanatory power of 18%. In the case of active unethical consumption behavior, showed that sex(${\beta}$=.16, p<.05), father's education(${\beta}$=-.15, p<.05), attitudes toward money as means of control(${\beta}$=.18, p<.5) and conspicuous consumption(${\beta}$=.36, p<.001) with an explanatory power of 26%.

As a part of the KIAPS Observation Processing System (KOPS), we have developed the modules of satellite radiance data pre-processing and quality control, which include observation operators to interpolate model state variables into radiances in observation space. AMSU-A (Advanced Microwave Sounding Unit-A) level-1d radiance data have been extracted using the BUFR (Binary Universal Form for the Representation of meteorological data) decoder and a first guess has been calculated with RTTOV (Radiative Transfer for TIROS Operational Vertical Sounder) version 10.2. For initial quality checks, the pixels contaminated by large amounts of cloud liquid water, heavy precipitation, and sea ice have been removed. Channels for assimilation, rejection, or monitoring have been respectively selected for different surface types since the errors from the skin temperature are caused by inaccurate surface emissivity. Correcting the bias caused by errors in the instruments and radiative transfer model is crucial in radiance data pre-processing. We have developed bias correction modules in two steps based on 30-day innovation statistics (observed radiance minus background; O-B). The scan bias correction has been calculated individually for each channel, satellite, and scan position. Then a multiple linear regression of the scan-bias-corrected innovations with several predictors has been employed to correct the airmass bias.

Purpose: This study is a descriptive research study to determine the level of professional autonomy, professional self-concept, and job satisfaction of emergency nurses, and to investigate their correlations and verify the effects of professional autonomy and professional self-concept on job satisfaction. Method: The subjects were 189 emergency nurses with a work experience of 1 year or more, in 14 hospitals located in B and U Metropolitan Cities. The study was conducted from July 20, 2014, to August 30, 2014. The measurement instruments for professional autonomy, professional self-concept, and job satisfaction were used as the measurement tools. The collected data were analyzed using the t-test, analysis of variance, Scheffe's test, Pearson's correlation coefficient, and multiple linear regression. Results: Job satisfaction among emergency nurses showed a significant positive correlation with professional autonomy (r=.28, p <.001), and with professional selfconcept (r=.50, p <.001) with sub-areas of professional practice (r=.79, p <.001), satisfaction (r=.64, p <.001), and communication (r=.25, p <.001). Factors affecting job satisfaction were satisfaction (${\beta}$=0.60, p <.001), followed by low professional autonomy (${\beta}$=-0.24, p <.001) and communication (${\beta}$=0.14, p =.008), which accounted in total for 48.3% of the effect. Conclusion: This study suggests that enhancing professional satisfaction, maintaining proper communication, and securing autonomy are required to improve the job satisfaction among emergency nurses.

Earlier studies conducted on lead-exposed workers have determined the reticulocyte count (RC) (%), but the parameters of Absolute Reticulocyte Count (ARC), Reticulocyte Index (RI), and Reticulocyte Production Index (RPI) were not reported. This study assessed the effect of lead (Pb) exposure on the status of reticulocyte count indices in workers occupied in lead battery plants. The present cross-sectional study was carried out on 391 male lead battery workers. The blood lead levels (BLL) were determined by using an Atomic Absorption Spectrophotometer. The RC (%) was estimated by using the supravital staining method. The parameters, such as ARC, RI, and RPI, were calculated by using the RC (%) with the red cell indices (RBC count and hematocrit). The levels of RBC count and hematocrit were determined by using an ABX Micros ES-60 hematology analyzer. The levels of reticulocyte count indices - RC (%), ARC, RI, and RPI significantly increased with elevated BLL. The association between BLL and reticulocyte count indices was positive and significant. The results of linear multiple regression analysis showed that the reticulocyte count (${\beta}=0.212$, P < 0.001), ARC (${\beta}=0.217$, P < 0.001), RI (${\beta}=0.194$, P < 0.001), and RPI (${\beta}=0.208$, P < 0.001) were positively associated with BLL. The variable, smoking habits, showed a significant positive association with reticulocyte count indices: RC (%) (${\beta}=0.188$, P < 0.001), ARC (${\beta}=0.174$, P < 0.001), RI (${\beta}=0.200$, P < 0.001), and RPI (${\beta}=0.151$, P < 0.005). The study results revealed that lead exposure may cause reticulocytosis with an increase of reticulocyte count indices.
