To probe the subclinical mastitis in a herd of cows in Chonnam district, the electrical conductivity(EC) of 825 foremilk samples were measured for 2 years. Normal (n=487) and mastitic(n=110) foremilk samples were classified by the California mastitis test (CMT) and direct somatic cell count(DSCC) and investigated the relations between the changes of the EC value and the calving history, age, days of postpartum, estrus and causative organism isolated. Obtained results are summarized as follows. 1. In the normal foremilk samples, positive correlation, though not significant, was found between the EC value and calving history (r=0.573) and age (r=0.247). 2. In the normal foremilk samples, the EC values were lowered at 30～120 days of postpartum through the whole lactation period and revealed a tendencies to higher values following the day of postpartum increased untill to the drying off (r=0.823), and the days of postpartum was recognized as one of a influencing factor on the EC value(p<0.05). 3. In the mastitic foremilk samples, significant correlation between EC value and resazurin reduction test (RRT) were observed (r=0.904, p<0.05). 4. In the mastitic foremilk samples, EC values were obtained in the E. coli infection as 63.9mM-NaCl, in the Streptococcus spp. infection as 60.5mM-NaCl and in the Staphylococcus spp. infection as 57.0mM-NaCl. 5. At day 0 of estrus, the mean EC values of normal and mastitic foremilk samples were 41.2mM-NaCl and 68.3mM-NaCl respectively and the EC value of day 0 of estrus was higher than that of days before and after estrus.

Purpose: To identify characteristics of chronic fatigue, difference between the duration of fatigue and characteristics of chronic fatigue, and association between chronic fatigue and related factors in adults. Method: The subjects for this study were 180 adults who had experienced fatigue for over one month The measurement tools were the Revised Fatigue Scale by Chalder et al. (1993), the Visual Analogue Scale-energy developed by Lee et al. (1991), the BEPSI (Brief Encounter Psychosocial Instrument) by Frank & Zyzanski (1988), Zung's self rating depression scale (1965) and life style items including exercise sleep, drinking smoking and diet as developed by the researchers. Results : Those who complained of fatigue over six months experienced higher disturbances in their daily life compared to those who had suffered from fatigue less than six months. There were a significant correlation between severity of fatigue and depression (r=.46, p<.001), stress (r=.41, p<.001), and sleep (r=.20, p<.01) Statistically significant relationships were found between severity of fatigue and amount of exercise per week (F=3.79. p<.05) disturbed sleep (t=-2.66, p<.01), number of times awakened during the night (F=3.48, p<.05) types of drinking (F=2.65, p<.05), and diet regularity (F=5.83, p<.01). The construction of a multiple regression model revealed an adjusted $R^2$ of .27 with the depression score serving the major predictor variables for severity of fatigue. Men and people in the younger age group were more energetic than women and those in other age groups. Also married people experienced more fatigue than people who were single. divorced or separated. Conclusion: In nursing interventions for fatigue, medical personnel should consider sociodemographic characteristics of the clients, ways to reduce of stress and counter disturbances in daily life and develop strategies for a health promoting life style.

This was a descriptive study clarifying the factors affecting family caregivers' sense of well-being. This study was conducted with 131 caregivers using structured self-reporting questionnaires and directly interviewing adult patients who had been under treatment in two general hospitals. The hospitals were located in M city from Aug. 10, 2000 until Sep. 2, 2000. The collected data were analyzed using SAS PC+ program, and the data were tested using descriptive statistics, t-tests, ANOVA, Pearson's Correlation Coefficient, and Stepwise Multiple Regression. The results of this study are as follows; 1) The variables affecting the caregivers' sense of burden were age (F=3.76, p=.0063), education level (F=4.67, p=.0015), monthly income (F=2.49, p=.0466), amount of assistance provided (F=4.19, p=.0037), and the relationship with patient before disease (F=9.49, p=.0001). 2) The variables affecting caregivers' sense of well-being were age (F=9.54, p=.0001), residing with patient (t=11.38, p=.0010), the period of caregiving (F=10.52, p= .0001), education level (F= 2.79, p=.0290), monthly income (F=3.04, p=.0196), and relationship with patient before disease (F= 10.51, p=.0001). Also, all of the variables which showed statistical significance. 3) In viewing the relationship between activities of daily living (ADL) and the senses of burden and well-being, a negative relation- ship between activities of daily living (ADL) and a sense of burden was found (r=-.640, p=.000). However, the relationship between activities of daily living (ADL) and a sense of well-being had a positive correlation (r= .232, p=.008). Also the relationship between the sense of burden and the sense of well-being was revealed to have a negative correlation (r=-.614, p=.000). 4) A sense of burden was the most important indicator to the well-being of the caregivers who took care of stroke patients (R2 =.36). In addition to this, living with the patient (45%), activities of daily living (51%), relationship with patient before disease (53%), and the family's monthly income accounted for 56% of the sense of well-being of the caregivers.

The purpose of this study was to evaluate the relationship between the osteoporotic condition and periodontal condition in postmenopausal women with periodontitis. Forty three female postmenopausal patients with no systemic disease were grouped into 3 groups by their periodontal conditions; 12 mild periodontitis, 11 moderate periodontitis and 20 advanced periodontitis. From each patient, age of menopause was taken, alkaline phosphatase(ALP) and osteocalcin (OC) in blood and deoxypyridinoline (DPD) in urine were measured. Bone mineral density (BMD) of lumbar spine (L2-L4) was measured by dual energy X-ray absorptiometry. Periodontal and osteoporotic parameters were compared among the groups and correlation coefficient between them was evaluated. The blood ALP and OC levels were similar among the groups with different periodontal condition, whereas the urine DPD level and BMD were significantly lower in advanced periodontitis group than the other groups(p<0.01). Probing depth was negatively related with BMD (r=-0.5, p<0.01) and positively related with patient age and the duration of menopause (r= 0.32 and 0.35 respectively, p<0.05). Clinical attachment loss was negatively related with BMD (r=-0.66, p<0.01), and positively related with urine DPD (r= 0.37, p<0.05). These results showed that postmenopausal women with advanced periodontitis had significantly decreased bone mineral density and suggests that decreased bone mineral density in postmenopausal women could be associated with periodontal tissue breakdown.

Purpose: This study aimed to investigate the perspective of consumers in healthcare services regarding patient safety. Methods: The study was a descriptive study using a self-reported questionnaire. The questionnaire was based on the Senior Empowerment and Advocacy in Patient Safety (SEAPS) questionnaire, which was designed to assess patient safety health beliefs. The survey was conducted online and a convenient sample of 302 adults participated in total. The reliability of the measurement (Cronbach's ${\alpha}$) was 0.758 in attitude (ATT), 0.546 in out-come efficacy (OE), 0.757 in self-efficacy (SE), and 0.703 in behaviors (BEH). Results: The average patient safety awareness score of the healthcare service consumers was 2.72 (ATT), 2.91 (OE), 2.87 (SE), and 2.27 (BEH). Our analysis indicated that there were no differences in ATT, BEH, or SE by gender, age, or education level. However, in OE and the total score of the four subscales, there were significant differences by age and gender. Correlations were identified between BEH and SE (r=0.409, p<.01), BEH and OE (r=0.202, p<.01), ATT and SE (r=0.358, p<.01), and OE and SE (r=0.241, p<.01). Conclusion: This study measured consumer perspectives concerning patient safety. The findings demonstrate the need for developing a measurement tool to assess consumer's perception of patient safety, considering Korean healthcare system and cultural context.

Purpose: The purpose of this study was to explore the correlates of body mass index (BMI), perceived health status (PHS), and the needs of functional games for the elderly in Korea. Methods: This is a descriptive study with convenience sampling. The data were collected from 363 older adults in S city who completed questionnaires asking about their BMI, PHS, needs for functional games, and general characteristics. Using the SPSS 20.0 program, data were analyzed. Results: The mean age was 65.4(${\pm}4.75$), ranging between 60-83 years old. Among the 363 subjects, 75.2% who were male, 55.9% chose "functional games are necessary," and 25.3% selected "functional games are absolutely necessary" for the elderly. There were statistically significant correlations between current PHS and comparing health to others (r=.827, p<.001), depression (r=-.330, p<.001), age (r=-.113, p=.032), respectively. In addition, there was a statistically significant correlation between comparing health to others and depression (r=-.292, p<.001). Conclusion: The study findings show that older adults have distinct needs and interests for functional games. Thus, we need to develop senior functional games to help make older adults more active with greater enjoyment to gain more health benefits. Interdisciplinary team approaches would work well for developing functional games in Korean considering the preferences of older people are similar.

The purpose of this study was to examine the relationship of the severity, depression and to identify factors influencing quality of sleep in Restless Legs Syndrome(RLS) patients. A total of 303 consecutive RLS patients were assessed by self questionnaires and participant's medical records were reviewed for obtaining their clinical information. The collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation, and multiple regression. The quality of sleep was positively correlated with symptoms(r=. 21, p<.001) and depression(r=. 37, p<.001). The results of multiple regression analysis showed that significant variables influencing the quality of sleep were depression(${\beta}=.35$, p<.001), age(${\beta}=.21$, p<.001), and severity(${\beta}=.15$, p=.005). The explanation power of this regression model was 21.0% and it was statistically significant. As a result, to improve their sleep quality, the nursing interventions are required for RLS patients who have the depression, age, and severity.

Purpose: The purpose of this study was to identify influencing factors on vision-related quality of life in patients with retinal diseases receiving intravitreal injections by examining relationships among anxiety, depression, coping, eye health behaviors and vision-related quality of life. Methods: One hundred and five outpatients who were diagnosed with macular degeneration and diabetic retinopathy were recruited from one university hospital during August 16, 2019 to March 25, 2020. Data were analyzed using descriptive statistics (frequency and percentage, mean, standard deviation), and t-tests, ANOVA, Scheffé test, Pearson's correlations, and stepwise multiple regressions using the IBM SPSS Statistics 25.0. Results: The vision-related quality of life according to general characteristics of retinal disease patients with intravitreal injection showed significant differences in age (F=3.01, p=.034), subjective economic status (F=5.83, p=.004), types of retinal disease (t=2.62, p=.010), and disease in both eyes (t=-3.04, p=.003). The vision-related quality of life showed a significant positive correlation with age (r=.24, p=.012), and negative correlations with anxiety (r=-.66, p<.001), depression (r=-.48, p<.001), and emotion-focused coping (r=-.20, p=.036). The hierarchical regression analysis indicated that factors affecting vision-related quality of life in patients with retinal diseases were anxiety and subjective economic status, accounting for 47.0% of the variances of the vision-related quality of life. Conclusion: Based on our results, health professionals need to pay attention to patients with low socioeconomic status due to frequent treatments. Also, a program needs to be developed to decrease anxiety for outpatients receiving intravitreal injections to improve their vision-related quality of life.
