Purpose: This study is to investigate the low back pain, social support, impediment in daily living activities and to identify factors affecting impediment in elderly farmer' daily living activities. Methods: The participants were 128 elderly farmers who had received nerve block. Data were collected using a structured questionnaire from February to March, 2018. They were analyzed using t-test, ANOVA, pearson's correlation coefficient, and linear multiple regression. Results: The score of low back pain was $6.27{\pm}1.69$ (10 points), that of social support $2.92{\pm}0.76$ (1~5 points), and that of impediment in activity of daily living $2.01{\pm}0.82$ (0~5 points). Factors affecting impediment in activity of daily living were found to include age (p=.017), daily hours of farm work (p<.001), fear for the nerve block (p<.001), low back pain (p<.001), and social support (p<.001); the explanatory power of these variables was 58.8%. Conclusion: This study has found the controllable factors affecting impediment in activity of daily living among the rural elderly engaging in farm work include low back pain, social support, and daily farming hours. Therefore, to reduce impediment in activity of daily living among them, it is necessary to develop nursing interventions that can improve impediment in activity of daily living through reduction of daily farming hours using local resources. It is also desirable to improve their health status by reducing low back pain, and develop and apply social supports with health education programs that fit the local resources and the needs of the rural elderly.

Djungarian hamsters show distinct seasonal rhythms in several physiological parameters. One of them is daily torpor that occurs in winter with decreased body temperature (about 1O-20$^{\circ}$C) during daytime. Daily torpor is induced by short-day photoperiod, food restriction and castration. But the mechanism to induce daily torpor has not been clarified. In the present study, we tried to clarify the process of daily torpor induction in detail. Adult male hamsters were kept in long photoperiod and high temperature (LP-HT) before the experiment and, thereafter, the animals were transferred to short photoperiod and low temperature (SP-LT), and they were kept in this condition for about six months. The daily rhythms of locomotor activity and body temperature were recorded every three-minutes by using the Minimitter telemetry system. Locomotor activity and body temperature showed very closely synchronized rhythms. All animals under LP-HT showed daily rhythms with higher locomotor activity and body temperature in nighttime than in daytime. Under SP-LT, there were two types of animals with and without showing daily torpor. Thus, they have individual differences in the response to SP -LT.

The Construction Standard Production Unit(CSPU) has been used for the standard cost estimate in public and private construction projects. However, It is questionable if the reliability and/or authenticity of the system is acceptable due to the lack of consistent enactment and/or revision procedures. This study identifies informational conditions and issues relative to using daily work report as a data collection method for enacting and/or revising CSPU system, and establishes the measures for improving the daily work report. This study aims on the information constitution of daily job-site report, daily manpower report, wages register for specialty contractors. According to the research results, most of necessary data were included in a daily job-site report. In conclusion, it is investigated that data of daily manpower report and wage register need to be included in a daily job-site report for understanding the current state of worker in the future.

Objectives : The purposes of present study were to identify weight increment in female psychiatric patients during hospitalization and to evaluate the relationship between weight gain and daily calorie intake, daily activity and other variables of disease itself. Methods : 20 patients were studied. Body weight were measured once a week, and daily activity(total amounts of walking/day) and total amount of daily calorie intake were measured twice a week. We examined psychiatric and medical illness history, eating disorders' history and family history of eating disorders and obesity. Results: Mean body weight and Body Mass Index(BMI) at admission are 49.40kg and 19.59kg/$m^2$. Mean weight increment during hospital stays of mean 65 days is 4.90kg. Mean amounts of daily calorie intake and daily activity(daily walks) were increased during hospital stays, but not statistically significant. The degree of weight increment is higher in longer hospital stay group, but not statistically significant. Mean body weight at admission of mood disorder group is higher than that of schizophrenia group, but not statistically significant. Conclusion : This results suggested that weight increment in female psychiatric hospitalized patients is present. However, it is not resulted by amount of calorie intake and daily activity level.

The purposes of this study were to find the correlation of social maladaptation, depression, ego resilience and daily life satisfaction, and to explore the mediating role of ego resilience between social maladaptation, depression and daily life satisfaction. The subject of the survey was 184 intermarried Korean men. The data were analyzed with frequency, Pearson's correlation and structural equation modeling by SPSS and AMOS. Instruments were social maladapatation and depression of Shin(2001)'s Mental Health Scale, Block and Kremen(1996)'s Ego Resilience Scale, and Bradburn(1969)'s Structure of Psychological well-being, and Olson and Barnes(1982)' Quality of Life. The major findings were as follows: Social maladapataion and depression were negatively correlated with ego resilience and daily life satisfaction. Ego resilience was positively correlated with daily life satisfaction. Ego resilience mediated the effects of social maladaptation, depression and daily life satisfaction. Social maladaptation and depression influenced ego resilience. Ego resilience influenced positively daily life satisfaction. In conclusion, it is important to intervene intermarried Korean men's daily life satisfaction through special education program and counseling in order to build ego resilience.

The purpose of this study was to examine the effects of mother and father's parenting efficacy, parenting stress on children's daily stress. The subjects were 292 children selected from 4 elementary schools and their mothers and fathers. Data was collected using the parenting efficacy index, parenting stress index, and children's daily stress inventory, and was statistically analyzed using t-test, one way ANOVA(Scheffe test), correlation analysis and multiple regression analysis. The study showed that there were some significant differences in children's daily stress according to the children's grade and gender. Correlation analysis indicated that the mother's parenting efficacy and children's daily stress had negative correlation, and also father's parenting efficacy and children's daily stress had negative correlation. Further, mother's parenting stress had positive correlation with children's daily stress, and father's parenting stress as well. It was also found that parenting efficacy of mother's general parenting ability, parenting efficacy of father's discipline ability, father's stress of difficult child, mother's educational distress, and children's gender were all significant predictors of the children's daily stress.

In order to investigate the relationship between daily herbage allowance (DHA) and daily herbage intake (DHI) on the points of leaf and stem masses, grazing experiments were carried out on the pasture of tall fescue (Festuca arundinacea Schreb.). The experiments consisted of four 3-days' grazing periods which were from August 14 to 17, August 17 to 20, October 12 to 15 and October 15 to 18 in 1990. The value of DHA was 32.1 to 84.3, and the value of DHI was 9.9 to 27.0. The index of leafiness (leaf to stem ratio, LSR) was 0.74 to 3.06. The relationship between DHI and DHA was quadratic. Both relationship of daily leaf intake (DLI) to daily leaf allowance (DLA) and that of daily stem intake (DSI) to daily stem allowance (DSA) were likely to be asymptotic forms, although DHI did not show any significant relationships to DLA nor to DSA. The relationship between DLI and LSR was quadratic, and a negative relationship was found between DSI and LSR. From the relationship of DLI to LSR and that of DSI to LSR, the relationship of daily intake of leaf and stem (DLSI) to LSR was derived as quadratic and the LSR value at which the maximum DLSI was attained was estimated. The DHA, DHI, DLA, DLI, DSA, DSI and DLAI were expressed as the same unit of g/kg live body weight/day.

Daily milk yields on test days were estimated using morning or afternoon partial milk yields collected by official agencies and the accuracy of the estimates was determined. Test-day data for milk yields consisted of 3,156,734 records of AM/PM partial milking measurements of 255,437 milking Holstein cows from 3,708 farms collected from December 2008 to April 2013. A linear regression model (LRM) was applied to estimate daily milk yields using alternate AM/PM milk yield records within lactation stages, milking intervals, and parities on every daily milk yield. The alternate statistical approach was a non-linear hierarchical model (NHM) in which Brody's growth function was implemented by reflecting an animal's physiological milk production cycle. When compared with LRM, daily milk yields predicted by the NHM were assumed to be functionally related to day in milk (or lactation) stage, milking intervals, and partial milk yields. Since the results were in terms of accuracies based on comparisons of different statistical models, accuracies of estimates of daily milk yields by NHM were close to those determined by the LRM. The average of these accuracies was 0.94 for AM partial milk yields and 0.93 for PM partial milk yields for first calving cows. However, the accuracies of AM/PM milk yield estimations from cows under a calving stage higher than the first parity were 0.96 and 0.95, respectively. Correlations between the estimated daily milk yields and the actual daily milk yields ranged from 0.96~0.98. These accuracies were lower for unbalanced AM/PM milking intervals and the first calving cows. Overall, prediction of daily milk yields by NHM would be more appropriate than by LRM due to its flexibility under different milk yield-related circumstances, which provides an idea of the functional relationship between milking intervals and days in milk with daily milk yields from statistical viewpoints.

The conventional Flow Duration Curve has limitations that it does not consider hydrologic persistence of daily discharge, that the daily discharge is greatly affected by the maximums or minimums, and that the date of occurrence and duration of a specific discharge cannot be known. In this study, we propose a Daily Mode Discharge Curve, which consists of aligning the daily discharge each year by the date of occurrence, calculating the daily mode discharge, and averaging them every 5 days. As a result of reviewing the long-term observational daily discharge data at 8 points upstream and downstream of the mainstream of the 4 major rivers in Korea, it was found that the daily discharge at all points shows hydrological persistence, and the distortion of it was alleviated by using Daily Mode Discharge Curve. We also suggest that the Daily Mode Discharge Curve is useful for utilizing reference discharge such as Drought, Low, Normal, Plentiful, and Flood Discharge.

Purpose : This study aims to investigate the effect of instrument-activities daily living training through client-centered home visitation on the cognitive functions, occupational performance, and instrument-activities daily living of elderly at the cognitive support grade(Grade6). Methods : The subject of this study was a 66-year-old woman living in G Metropolitan City, who has been diagnosed with Alzheimer's and mild dementia. The study period was from March 17, 2020 through June 12, 2020, and the A-B-A' design, among the individual case experiments, was adopted as the study design. For the data analysis, descriptive statistic and visual analysis using graph were used for the change of cognitive functions, occupational performance, and instrument-activities daily living. Results : The instrument-activities daily living provided through client-centered home visitation improved the subject's cognitive functions, occupational performance(performance, satisfaction) and instrument-activities daily living. Conclusion : This study showed that daily life training through client-centered home visitation can help elderly people at the cognitive support grade select for themselves the problems of daily life caused by cognitive decline and practice specific action plans, thereby enabling them to maintain and improve the cognitive functions necessary for the performance of activities, such as comprehension, memory, and thinking skills. In addition, it is thought that the activities based on the subject's preferences, performance, and sense of importance assured the subject of feelings of motivation and the possibility of participation, and had a positive effect on the subject's performance speed and rate. With the above in mind, Instrument-activities daily living client-centered home visitation is proposed as a potential practical intervention program for individuals. It can help elderly people at cognitive support grade to maintain and improve their functions, thereby delaying the progress of their condition to severe dementia.
