Objective: This study aimed to evaluate the zygomaticotemporal suture (ZTS) maturation, analyze the age distribution patterns of ZTS maturation stages, and investigate the relationship between ZTS and cervical vertebral maturation (CVM). Methods: A total of 261 patients who underwent cone-beam computed tomography (112 males, mean age, 13.1 ± 3.3 years; 149 females, mean age, 13.7 ± 3.1 years) were examined to evaluate the ZTS stages. The ZTS stages were defined based on a modified method from previous studies on zygomaticomaxillary sutures. Differences between groups and correlations between indicators were analyzed using the Spearman correlation test, intraclass coefficient of correlation (ICC), one-way analysis of variance and rank sum test. Statistical significance was set at p < 0.05. The diagnostic value of CVM stages in identifying ZTS maturation stages was evaluated using positive likelihood ratios (LRs). Results: A positive relationship was found between the ZTS and CVM stage (r = 0.747, ICC = 0.621, p < 0.01) and between the ZTS stage and chronological age (r = 0.727, ICC = 0.330, p < 0.01). Positive LRs > 10 were found for several cervical stages (CSs), including CS1 and CS2 for the diagnosis of stage B, CS1 to CS3 for the diagnosis of stages B and C, and CS6 for the diagnosis of stages D and E. Conclusions: The ZTS maturation stage may be more relevant to the CVM stage than to the chronological age. The CVM stages can be good indicators for clinical decisions regarding maxillary protraction, except for CS4 and CS5.

Crossbred (Bos taurus${\times}$Bos indicus) calves were used from birth till 14 weeks of age to evaluate three sources of protein that differed in ruminal degradability viz. groundnut cake alone (HD) or in combination with cottonseed meal (MD) and meat and bone meal (LD), when fed along with two sources of non-structural carbohydrates viz. raw (R) and thermally processed (P) maize. Twenty four new born calves were arranged in six groups in a $3{\times}2$ factorial design and fed on whole milk up to 56 d of age. All the different calves received calf startes along with green oats (Avena sativa) from 14 d of age onwards free-choice. A metabolism trial of 6d starters duration, conducted after 90 d of experimental feeding, revealed greater (p<0.05) digestibility of DM, OM, total carbohydrates, NDF and ADF in calves fed on the P diets than on the R diets promoting greater (p<0.05) metabolizable energy intake. The digestibility of NDF was higher (p<0.01) on LD diets where as calves on MD diets exhibited significantly lower digestibility of ADF (p<0.01). The retention of nitrogen per unit metabolic body size was significantly (p<0.05) higher on the LD-P diet than on the diet HD-P which, in turn, was higher (p<0.05) than that of HD-R. Nitrogen retention as percentage of intake was significantly greater (p<0.05) on LD-P than on LD-R diets (52.2 vs. 36.4%). Also, P fed calves utilized nitrogen more efficiently than the R fed as shown by retention of significantly greater proportions of intake (47.4 vs. 40.9%) and absorbed (65.8 vs. 59.5%) nitrogen. Calorimetric evaluation of the diets through open-circuit respiration chamber revealed that the dietary treatments had no impact on methane production by calves. The intake of DE and ME was improved (p<0.01) because of maize processing resulting in greater (p<0.01) retention of energy. The protein degradability exerted no influence on the partitioning or retention of energy. A significant interaction between cereal and protein types was evident with respect to retention of both nitrogen (p<0.01) and energy (p<0.05). In conclusion, no discernible trend in the influence of cereal processing was apparent on the dietary protein degradability, but the positive effect of cereal processing on energy retention diminished with the increase in dietary undegradability.

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).

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.

The dental characteristics created by acquired dental treatments can be used as age estimators. This pilot study aimed to analyze the correlation between the number of teeth observed for dental characteristics and chronological age and to develop new non-invasive age estimation models. Dental features on panoramic radiographs (420 radiographs of subjects aged 20-89 years) were classified and coded. The correlation between the number of teeth for each selected code (codes V, X, T, F, P, and L) and age was observed, and multiple regression was performed to analyze the relationship between them. Eleven regression models with various combinations of dental sextants were presented. The model with the data from both sides of the posterior teeth on both jaws showed the best performance (root mean square error of 14.78 years and an adjusted R² of 0.461). The model with all teeth was the second-best. Based on these results, we confirmed statistically significant correlations between certain dental features and chronological age. We also observed that some regression models performed sufficiently well to be used as adjunctive methods in forensic practice. These results provide valuable information for the design and performance of future full-scale studies.

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.
