Purpose: This study was conducted to investigate physical health status. depression. activities of daily living (ADL & IADL) of the low-income elderly who live alone in urban areas. Method: The subjects were the 400 low-income elders who live alone in Daegu city and the following instruments were used: 1. The number of self-reported physical health problems and present diseases: 2. CES-D scale for depression by Jo Nam-Oak et al. (1998): and 3. ADL scale by Katz (1989) and IADL scale by Lawton and Brody (1969). Results: 1. Visual difficulty was the most prevailing problem (55.3%) among physical problems. the second bowel elimination and the third hearing disturbance. As for present diseases. arthritis (26.5%), hypertension(24.3%) and DM (11.8%) were the most common diseases. 2. There were significant differences in physical health status according to age (t=3.115. p=.045). kind of medical security (t=-1.973. p=.049). perceived life satisfaction (F=4.966. p=.007) and the number of present diseases (F=2.937. p=.033). 3. There were significant differences in depression according to sex (t=-3.758. p=.000) . kind of medical security (t=-4.368. p=.000). perceived life satisfaction (F=35.743. p=.000) and the number of present diseases (F=4.246. p=.006). 4. There were significant differences in ADL according to sex (t=-2.136. p=.033) and age (F=4.863. p=.008). and in IADL according to sex (t=4.552, p=.000), age (F=3.090. p=.047) and kind of medical security (t=-3.306. p=.001). 5. Physical health state was correlated positively with both the number of present diseases (r=.140. p=.005) and depression (r=.352. p=.000), and negatively with ADL (r=-.176. p= .000) and IADL (r= -.230. p=.000). Depression was correlated positively with the number of present diseases (r=.169. p=.001) and negatively with both ADL (r=-.139. p=.005) and IADL (r=-.203. p= .000). Conclusion: The results of this study suggest that general characteristics are important factors for physical health status, depression. ADL and IADL of the low-income elderly who live alone and there are close relations among physical health status, the number of diseases, depression, ADL and IADL. Therefore, these results must be reflected in community health programs for the low-income elderly who live alone. In addition, this kind of study must be extended to the low-income elderly who live alone in rural areas.

The purposes of the study were to develop an instrument for family value and to identify the relationships of family value, family hardiness, and family adaptation by appling the family value scale to family with cancer children. The study was conducted in three phases. 1) A survey was conducted from July 20 to August 20, 1999 and 18 items of general family value scale was modified from the data of 153 fathers and 164 mothers. 2) In-depth interviews were made with 29 parents of cancer children from April 20, 1998 to May 20, 1999 to develop family value scale with cancer children, and 12 statements were developed. 3) The final survey was conducted from July 18, 2000 to August 30, 2000 and the data from 309 parents of children who are diagnosed as cancer, 18 or less years of age, and treated either hospitalized or at the outpatient clinics were analyzed to identify the relationships of the concepts. The data analysis utilized SAS 6.12 and LISREL 8 for descriptive statistics, correlation, and Regression for path analysis. The study findings are as follows. The psychometric testing of general family value scale was Cronbach's alpha = 0.78. The reliability of the family value scale with cancer children showed the reliability as Cronbach's alpha = 0.73. Demographic characteristics showing significant correlations were cancer children's age, period of illness, period after completing treatment, mother's age, mother's education level, monthly income, payment type, confidence with health professional, and severity of children's illness. The correlation coefficients among major variables showed that family stressor was positively related with family strains(r=0.33, p<.001), and negatively related with family hardiness(r=-0.21, p<.001). Family strains was negatively related with family hardiness(r= -0.41, p<.001) and family adaptation(r=-0.46, p<.001). Correlations of family hardiness was positive with family value with cancer children(r=-0.31, p<.001), and negative with general family value(r=-0.16, p<.01). Family hardiness was positively related with family adaptation(r=0.35, p<.001). The causal relationship between study variables showed that family strains predicts general family value(γ=0.12, t=2.02), family value with cancer children predicts family hardiness(γ=0.31, t=6.30), family strains predicts family hardiness(γ=-0.40, t=-7.70), family value with cancer children predicts family adaptation(γ=-0.23, t=-4.11), and family hardiness predicts family adaptation(γ=0.43, t=7.78).

Objectives : Based on the fact that cognitive functions decline known as comorbid symptoms of depression can precede depression, this study seeks to observe the effects of depressive symptoms and anxiety symptoms on cognitive function in healthy subjects. Methods : To recruit 50 general populations to evaluate cognitive and clinical symptoms and to find out the effects of clinical symptoms on cognitive functions, Pearson correlation and multivariate regression were conducted. Correlation analysis of subdomain cognitive function was conducted for reliability analysis. Results : Trail making test-B that evaluates the execution function correlates with depressive symptoms (r=0.300, p=0.03) and age (r=0.323, p=0.02). Depressive symptoms (β=0.304, p=0.03) and age (β=0.335, p=0.01) were significantly related to Trail making test -B (Adjusted R²=0.148). Subjective cognitive tests correlates with anxiety symptoms (r=0.434, p=0.002). In the correlation between cognitive functional items, Subjective cognitive tests was found to be correlated with other test except Spotter. Conclusions : In this study, depressive symptoms contribute independently to executive functions in addition to demographic characteristics such as age and duration of education. Given that cognitive decline is a common long-term clinical outcome in depression, we expect active early intervention and evaluation of cognitive function to be helpful.

The purpose of this . study is to examine the unsatisfactory factors of the physical therapists and to obtain the materials necessary to comply with these factors by analysing their service performance and job satisfaction, To accomplish these purposes, this study was carried out by using the questionnaires 206 physical therapists registered in the Korean Physical Therapists Association, for 35 days from January 7 to February 10, 1990. The result of this study is summarized as follows. 1. Of total respondents, the male accounted for 54.4 percent, while the female for 45.6 percent. Their age showed that 20s accounted for 65.0 percent, while the service period less than 3 years accounted for 66.5 percent. In addition, 63.6 percent of them served at the general clinics. 2. The general clinics caused the physical therapists to serve for 10 hours or more per day, where their therapy room located in the underground accounted for 41.3 percent. Their health diagnosis status indicated that nondiagnosis accounted for 63.2 percent. The number of the served patients fer a day showed that 20-30 accounted for 37.4 percent, while 30 persons or more for 25.7 percent. 53.4 percent of total subjects was unsatisfied with their duty quantity. And, the monthly salary indicated that 500,000 or less accounted for 72.3 percent. 3. The average marks by their job satisfaction factors indicated 4.42 for duty importance, 4.02 for recognization of specialized job, 3.98 for ability exercise, 1.99 for promotion possibility, 2.28 for reasonable salary, and 2.41 for welfare system, respectively, based on 5 full marks. 4. The summarized job satisfaction by factors indicated that the relation with the doctor accounted for 57.8 percent, the satisfaction status with the existing job for 53.4 percent, the ability development for 41.8 percent, respectively, and the salary for 10.2 percent. Then, the satisfaction by sex showed that the male was generally satisfied with the ability development (p<0.05), the relation with the doctor (p<0.01), and the satisfaction with the existing job, while the female was satisfied with the duty quantity(p<0.05), salary, and the situation guarantee (p<0.05). On the other hand, the satisfaction by age indicated that the subject of the lower age were satisfied with the ability development (p<0.01), the relation with the doctor(p<0.05), the salary, and the situation guarantee. Also, the satisfaction by the service section showed that the physical therapists serving at the general hospital were satisfied with the ability development (p<0.01), the duty quantity (p<0.01), the salary(p<0.01), the situation guarantee(p<0.01), and the satisfaction with the existing duty (p<0.05), while the physical therapists at the hospital and the rehabilitation center were unsatisfied with the salary (p<0.01). In addition, The satisfaction with the service period at the existing section indicated that the physical therapists less than 3 years were highly satisfied with the ability development, the relation with the doctor, the situation guarantee, and the existing duty(p<0.05), while the physical therapists more than 6 years tended to show the lower satisfaction, And the satisfaction with the monthly salary indicated that the higher the monthly salary, the higher the satisfaction with the relation to the doctor(p<0.05), the duty quantity(p<0.01), the salary(p<0.01), and the situation guarantee (p<0.01). 5. The correlation between general characteristics and job satisfaction factors indicated that the sex was directly correlated to the marital status (r=-0.442), while it was reversely correlated to the age (r=-0.564) , total career (r=-0.229), and the relation with the doctor (r=-0.233). Additionally, the age was directly correlated to the total carreer (r=-0.677), and the service period at the existing section (r=0.491), while the age was reversely correlated to the marital status (r=-0.678). Accordingly, the higher job satisfaction of the physical therapists was related to factors such as their duty importance, recognization of specialized occupation, ability exercise, autonomy, relation to colleagues, decision-making's consideration, and relation with the doctor, while the lower job satisfaction includes the opportunity of promotion, salary, welfare system, service time, duty quantity, and situation guarantee. For this reason, if the factors of the lower job satisfaction are solved, then it will be possible to encourage the motive of these physical therapists, and the acyivate their duties. More over, it is also possible to improve the medical service, Additionally, if the general physical therapy room in the hospital and in the public health center are established, more development should be accomplished in the physical therapy.

The author had selected the roots and root-canal as measurable parts and sought the area ratio by measuring the respective areas of the root. Further, heplotted out a root caual index and studied the correlation with age. The teeth used as reserch material were permanent maxillary central incisors of Korean female. Some 296 teeth of known age were selected on condition that there is no caries or filling material and that they were not malformed in showing normal signs in roentgenograms. The $3" {\times} 4"$ printing paper so as to measure easily. On the ocassion of measureing the area of measured parts with a planimeter (Koizumi, type kp-27, Japan), the cervical lines were joined up into a straight line on a photograph (Figure 1) Root canal index = Area of the root / Area of the root canal The results of the root canal index in Korean female age groups were as follows : 1. The root canal index of maxilary central incisor in women was 4.74 im 20 years of age, 5.44 in 30, 5.90 in 40, 6.32 in 50, 6.63 in 60 in the order. 2. Root canal index and age were in positive correlation ; there was a tendency that the root canal index increase as age advances. 3. The regression equation was as follows : Y = 5.36x + 7.71 (r = 0.54, n= 296 ) (Y = estimated age, x = root canal index)

Purpose: This study aimed to investigate the impact of family resilience on caregiver well-being across various age groups of children diagnosed with ADHD (attention-deficit/hyperactivity disorder) groups (0-5, 6-11, and 12-17 years). Methods: Utilizing secondary data from the 2022 US National Survey of Child Health, this cross-sectional study involved 2,752 children who were formally diagnosed with ADHD. Statistical analysis included descriptive analysis, Spearman's rank correlation, chi-square tests, and linear regression, conducted using SPSS version 27. Results: The study revealed a moderate positive correlation (r=.35, p<.001) between family resilience and caregiver well-being. Controlling for covariates, family resilience accounted for 25.2%, 21.1%, and 22.1% of caregiver well-being variance in age groups 0-5, 6-11, and 12-17 years, respectively. Additionally, factors like employment status, family structure, and caregiver age showed varying influences on caregiver well-being across these developmental stages. A consistent pattern emerged across these age groups: unemployment and non-traditional family structures were associated with negative impacts on caregiver well-being, whereas older caregiver age positively influenced well-being. Conclusion: This research underscores the importance of age-specific family resilience strategies to improve caregiver well-being and family interactions in ADHD contexts. Investigating these aspects through qualitative studies across various cultures could deepen our understanding of well-being and inform culturally sensitive interventions.

In view of the nationel health, the health of women during their childbearing age is important. In Korean, several studies reported that incidence of anemic case was high among these group. The present study was conducted to investigate the dietetic life and dietetic problems among college women during their child-earing age. One hundred thirty seven college women (Age ranges 18.5 to 21.8) who lived in Gwangju area were randomly selected and were practiced dietary survey by three day records in November 1979. Also, hemoglobin level was determined. The result are summarized as follows; their diets were found to be lacking I total amounts of food it takes (878.6$\pm$266.9 gm) and in such foods as cereals, potatoes, beans, green and yellow vegetables, oils and fats and small fishes. but animal food intakes were sufficient in such foods as fishes, meats and eggs. The average calorie intake (1729.3$\pm$437.0kcal) was insufficient against R.D.A (2000kcal) and the daily energy expenditure (2024.7kcal). Lacking nutrients were Fe and Vitamin A these percentages of R.D.A. were 75.61% and 80.14% The mean body height (16.1$\pm$8.1cm) was higher tendency compared to other studies, but the mean body weight (49.8$\pm$4.1kg) was lighter. The average Hb level was 12.75$\pm$2.94gm%, and 13.64% of the subjects was anemic (12gm% below) The differences of each nutrient intake between the anemic and the healthy group not noted statistically significant.

The age and growth of rabbit fish, Siganus fuscescens were investigated from samples monthly collected in the coast of Jeju island, Korea from February to December 2012. Ages were determined from annuli in otoliths, and annuli were formed in one or two months immediately after spawning once a year. Also, main spawning period was estimated between July and August, thus rings were considered as annual marks. The von Bertalanffy growth equations estimated from a non-linear regression method were $L_t=37.24(1-e^{-0.33(t+1.24)})$ ($R^2=0.92$) for female and $L_t=31.44(1-e^{-0.45(t+1.23)})$ ($R^2=0.90$) for male, and the growth between female and male was different.

The purpose of this study was to identify the relationships of optimistic bias about gastric cancer, self-efficacy of healthy dietary behavior and unhealthy dietary habit in Korean adult men. The subjects were 394 men aged from 20 to 64 who lived in Seoul, Kyonggi Do, Kwang-Ju, Jeonnam Do. Data was collected by questionnaire surveys using convenient sampling. The instruments used for this study were extracted and modified from Lee's(2003). The collected data was analyzed using descriptive statistics, Pearson correlation coefficient, and stepwise multiple regression with SPSS/PC 10.0 version. Unhealthy dietary habit in adult men indicated a significantly negative correlation to optimistic bias about gastric cancer(r=-.159, p=.002) and self-efficacy of healthy dietary behavior(r=-.470, P=.000). The most significant predictors influencing unhealthy dietary habit in adult men were age and self-efficacy of healthy dietary behavior. The variance explained was about 24%. These results suggested that men of young age and lack of self-efficacy of healthy dietary behavior are likely to have unhealthy dietary behavior. Therefore, considering age and facilitating self-efficacy are needed in nursing education and intervention for dietary habit change.

Purpose: This study was to identify the relationship between fatigue and sleep disturbance in adult women so as to provide basic data for developing a women's health promotion program and nursing intervention. Method: A convenience sample of 184 women who visited a Well-baby clinic at P city Maternal child center during October in 2004 was obtained. Data was collected by self-administered questionnaires. Results: The Subjects' mean age was 36.87 years and 70% were employed and had more education than high school. The mean level of fatigue was 56.65, mean sleeping hours were 6.54, and time until falling asleep was 17.58 minutes. Scores of fatigue differed by subject's age, level of education, and menstruation status. In addition, sleeping hours differed by age, occupation status, and income level. There were significant low levels of correlation between fatigue and sleeping hours (r=-.16) and getting up too early (r=-.15). Conclusion: This study concludes that fatigue and sleeping patterns have a significant relationship.
