The purpose of this study was to examine difference in life satisfaction by social activity type in baby boomers. Sampling 1,115 baby boomers, gender and region were assigned. A questionnaire survey was carried out from August to October in 2011. As a result of research, first, the typology of social activity in baby boomers includes 3 groups. The passive social-participation type is the cluster to which 36.8% of the baby boomers belong. They do not join income activity or civic-group activity at all. A case of doing religious activity or family activity includes a minority. There are primarily lots of women and posteriori baby boomers. Academic background level or household income is lower compared to other clusters. The life satisfaction level is moderate. Second, the active social-participation type is the cluster to which 33.8% of the baby boomers belong. They are positive in all the social activities including income activity. What there are lots of women and posteriori baby boomers is similar to the passive social-participation type. However, the academic background or the averagely monthly household income is the highest compared to other clusters. Even the life satisfaction level is the highest. Third, the economic activity orientation type is the cluster to which 29.4% of the baby boomers belong. They participate in income activity, but don't participate in civic-group activity, educational activity, and social activity such as spending time alone. Distribution of priori-and-posteriori baby boomers, distribution of academic background, or monthly household income is moderate level of other clusters. However, unlike other clusters, there are many men. The life satisfaction level is the lowest. Based on result of this study are suggested ways to improve in life satisfaction by social activity type in baby boomers.

The purpose of this study was to examine relations on the autonomy, nursing performance based on the awareness and satisfaction of electronic medical record system for nurses. This Study was a descriptive survey design using convenience sampling. There were 194 general hospital nurses, who agreed to participate in this study, taken a structured questionnaire during august 2013. SPSS 20.0 version was used for descriptive analysis, frequency, percentage, mean, standard deviation, independent t-test, one-way ANOVA and Pearson correlation coefficiency. The major findings of this study were as follows. The mean score on the awareness of EMR was 3.68, the mean score on the satisfaction was 3.47 and nursing autonomy mean score was 3.25, nursing performance mean score was 3.55. There were significant differences in the awareness according to working field and computer certificate. There were significant differences in satisfaction depending on whether they held computer certificates Head nurses and the above scored significantly higher in nursing performance compared to nurses at the lower position. Also, higher awareness was significantly related to higher satisfaction. Higher satisfaction was significantly related to higher nursing autonomy and performance. The findings of this study imply that nurses need to raise their EMR awareness and satisfaction and make best used of their qualification with their computer certificate.

The purpose of this study is to investigate the relationship between organizational culture, organizational trust and organizational performance of special guard organization. This study had selected special guards from 4 different private guard companies which are in Seoul area on March 2011. Using Judgement Sampling, 161 samples were drawn for the use of final analysis. Questionnaire used in this study was consisted of the total 42 question, and executed frequency analysis, factor analysis, reliability analysis, correlation analysis, multiple regression analysis, path analysis by SPSSWIN 18.0. The Cronbach's ${\alpha}$ value which represents the reliability of the survey came out to be over .592. The results are following: First, the organizational culture of special guard organization affects organizational trust. That is, when a developmental, reasonable, consensual and hierarchical culture is activated, cognitive emotional and behavioral trust is increased. Second, organizational culture of special guard organization affects organizational performance. That is, when a reasonable and consensual culture is activated, job-satisfaction becomes higher. On the other hand, when a developmental, reasonable and hierarchical culture is activated, organizational flow becomes higher. Third, organizational trust of special guard organization affects organizational performance. That is, when a cognitive emotional and behavioral trust works highly, job-satisfaction and organizational flow is increased.

Earworm is very useful animal in soil ecosystem, however it is harmful for golf courses because they introduce many cast on turfgrass that reduces turf uniformity and play quality. However, no information has found on earthworm diversity and seasonal fluctuation in different Korean golf courses. In this study, we focused to carry out earthworm species composition and seasonal population structure in turfgrass of golf courses. During spring and fall season survey with direct digging and tea saponin drenching sampling in 5 different golf courses, 6 species under 3 families of earthworms were collected. Earthworm species composition and density was different among the golf courses. Aporrectodea caliginosa in Lumbricidae was dominant species in Anseong and Dongrae Benest Golf Club; however Amynthas carnosus in Megascolecidae was dominant species in Anyang and Glenrose Golf Club. Ap. caliginosa was collected only aclitellum in July and Am. carnosus was collected aclitellum and clitellum in August in golf courses. Seasonal population of earthworm was different depending on earthworm species (Am. hupeiensis was the highest in August and Ap. caliginosa was in April) however small number of collected earthworm species were not dominant trend in golf courses.

Objectives : To determine the prevalence of prostatitis symptoms in the general population by questionnaire survey and to measure the effect of prostatitis symptoms on quality of life(QOL). Materials & Methods : A cross sectional community-based epidemiologic study was performed on 2,034 men, living in the Seoul metropolitan area using stepwise random sampling. Out of 2,034 interviewees, 1,356 men who were older than 40 and provided sufficient information were selected for this study. The questionnaires were completed by well trained interviewers. Contents of the questionnaires included demographic data, the Prostatitis Symptom Index(PSI), the International Prostate Symptom Score(IPSS), a general health questionnaire section and a sexual health questionnaire section. The PSI was composed of a sum of the scores from three questions about dysuria, penile pain and perineal pain and it ranged 0 to 12. Incidence of prostatitis symptoms was defined by a score of 4 or more and the reference group was defined as consisting of those with a score of 3 or less. The rate of incidence of prostatitis symptoms was assessed according to age and the difference of QOL between the prostatitis symptoms group and the reference group. Results : The overall positive rate of prostatitis symptoms measured by the PSI, in men older than 40, living in the Seoul metropolitan area, was 4.5%(61/1,356), adjusted to 4.8% by the relative proportion of this age group in the general population of the Seoul metropolitan area as compared to Korea and the World. The proportion of the group with prostatitis symptoms assessed by the PSI did not increase with age although the proportion of participants with moderate to severe lower urinary tract symptoms (LUTS) did increase with age. The group with prostatitis symptoms suffered from a much greater incidence of LUTS compared to the reference group (p<0.05). The QOL scores of the IPSS, and the general health and sexual health status of the group with prostatitis symptoms, were worse than those of the reference group.(p<0.05). Conclusions : The positive rate of prostatitis symptoms in men older than 40, living in the Seoul metropolitan area, was 4.8% and it didn't increase with age. The general QOL of the group with prostatitis symptoms was much worse than that of the reference group.

The purpose of this study was to examine the drinking awareness of medical and health-related majors in a bid to find out the impact of their drinking awareness on drinking. The subjects in this study were 153 students who were selected by rendem sampling from colleges located in two different cities in the province. Data collection was performed from may 1 to september 20, 2011 with total 153 college students. Out of them, 86 students majored in medical departments, and 67 students were in the health-related departments. After a self-administered survey was conducted, the following findings were given: A great deal of the students who accounted for 75.8 percent were ever disturbed in daily routine life by drinking over the past year. As for the influence of drinking awareness on the amount of drinking, the amount of drinking was under the significant influence of the following five items. The first was that alcohol was an energizer(p<.001), and the second was that drinking led to a sound sleep(p<.01). The third was that I drank too much with my close friends often(p<.05), and the fourth was that alcohol used as a hangover-chaser was conducive to a hangover(p<.05). The fifth was that alcohol had the largest impact on the liver(p<.05). All the variables made a 43.4% prediction of the amount of drinking. In conclusion, the medical and health-related majors who learned about the impact of drinking on the human body in a firsthand or secondhand manner had a tendency to drink a less amount of alcohol and do less binge drinking. It's advisable to take advantage of the knowledge of medical and health-related majors on the human body and drinking as resources of anti-drinking education.

BACKGROUND/OBJECTIVES: Despite successes recorded in combating iodine deficiency, more than 2 billion people are still at risk of iodine deficiency disorders. Rural landlocked and mountainous areas of developing countries are the hardest hit, hence the need to explore and advance novel strategies such as biofortification. SUBJECTS/METHODS: We evaluated adoption, purchase, and consumption of iodine biofortified vegetable legumes (IBVL) using the theory of protection motivations (PMT) integrated with an economic valuation technique. A total of 1,200 participants from three land-locked locations in East Africa were recruited via multi-stage cluster sampling, and data were collected using two, slightly distinct, questionnaires incorporating PMT constructs. The survey also elicited preferences for iodine biofortified foods when offered at a premium or discount. Determinants of protection motivations and preferences for iodine biofortified foods were assessed using path analysis modelling and two-limit Tobit regression, respectively. RESULTS: Knowledge of iodine, iodine-health link, salt iodization, and biofortification was very low, albeit lower at the household level. Iodine and biofortification were not recognized as nutrient and novel approaches, respectively. On the other hand, severity, fear, occupation, knowledge, iodine status, household composition, and self-efficacy predicted the intention to consume biofortified foods at the household level; only vulnerability, self-efficacy, and location were the most crucial elements at the school level. In addition, results demonstrated a positive willingness-to-pay a premium or acceptance of a lesser discount for biofortification. Furthermore, preference towards iodine biofortified foods was a function of protection motivations, severity, vulnerability, fear, response efficacy, response cost, knowledge, iodine status, gender, age. and household head. CONCLUSIONS: Results lend support for prevention of iodine deficiency in unprotected populations through biofortification; however 'threat' appraisal and socio-economic predictors are decisive in designing nutrition interventions and stimulating uptake of biofortification. In principle, the contribution is threefold: 1) Successful application of the integrated model to guide policy formulation; 2) Offer guidance to stakeholders to identify and tap niche markets; 3) stimulation of rural economic growth around school feeding programmes.

This study investigated population characteristics that influencing treatment service use of people who are voluntarily using drug dependency treatment services by using logistic and hierarchical regression analysis. The research model of the current study was driven by the framework of the 'the Behavioral Model of Health Services Use(the Andersen model)' that has been broadly applied to study on health behavior. This study used data from a sample group of 80 adults by using purposive sampling. This study found that some predisposing factors, enabling factors and need factors have direct effects on service use. In detail, individuals who graduated from high school use drug dependency treatment utilities more than those who did not. Further, individuals who were given more support from family, peers, or others, use the treatment utilities more frequently and were more willing to use the utilities continuously. Furthermore, the greater the perceived need felt by the dependent, the greater the tendency to enter hospitals or shelters. The important implications of this study for social work practice and social policy can be summarized as follows: first, this study supports the idea that intervention for drug dependents in Korea should be focused on environment resources rather than population characteristics; and government must support drug dependent treatment systems; the present study was the first to investigate Korean drug dependents through taking a more positive view, as well as the first to apply 'the Behavioral Model of Health Services Use', and as such represents an example of how studies could be productively conducted in the future. Despite these implications, there remain some limitations in this study. These include the following: limitation in generalizability of the results; the cross-sectional nature of the study design; survey research through the questionnaire method; using foreign scales; and the difficulty of classifying treatment settings.

The goal of this study is to explore ways to restructure Convergence Elective Courses in science in preparation for the high school credit system, ahead of the 2022 revised science curriculum. This study started from the problem that the 2015 revised science curriculum has not guaranteed science subject choice for students with non-science/engineering career aptitudes. To this end, a survey was conducted by randomly sampling high schools across the country. A total of 1,738 students responded to the questionnaire of 3 science elective courses such as Science History, Life & Science, Convergence Science. In addition, in-depth interviews with 12 science teachers were conducted to examine the field operation of these three courses, which will be classified and revised as Convergence Elective subjects in the 2022 revised curriculum. According to the results of the study, high school students perceive these three courses as science literacy courses, and find these difficult to learn due to lack of personal interest, and difficulties in content itself. The reason students choose these three courses is mainly because they have aptitude for science, or these courses have connection with their desired career path. Teachers explained that students mainly choose Life & Science, and both teachers and students avoid Science History because the course content is difficult. Based on the research results, we suggested ways to restructure Convergence Electives for the 2022 revised curriculum including developing convergence electives composed of interdisciplinary convergence core concepts with high content accessibility, developing convergence electives with core concepts related to AI or advanced science, developing module-based courses, and supporting professional development of teachers who will teach interdisciplinary convergence electives.

This study analyzed the path through which elderly discrimination experience, sense of loss, and depression lead to suicidal ideation by verifying the influence of elderly discrimination experience on suicidal ideation and the mediating effect sense of loss and depression. The subjects of the study were a 1:1 in-depth interview survey of 400 elderly people aged 65 or older using stratified sampling methods by region and type of 31 city, county, and district the elderly welfare welfare centers(10 locations) in Gyeonggi-do. As a result, a total of 360 samples were finally analyzed. It was verified through frequency analysis, descriptive statistics analysis, correlation analysis, structural equation and bootstrapping analysis methods using SPSS 25.0 and AMOS 23.0. As a result of the study, first, it was found that the more the elderly experienced discrimination, the higher the suicidal ideation. Second, the effect of sense of loss was partially mediated on the effect of discrimination experience on suicidal ideation in the elderly. Third, the feeling of depression was found to play a partial mediating role between the experience of discrimination among the elderly and suicidal ideation. Based on the results of this study, policy and practical suggestions were made to alleviate the suicidal ideation of experiences of discrimination against the elderly and sense of loss and depression to prevent suicide among the elderly.
