This study of variables associated with maternal monitoring of child's whereabouts and daily activities was conducted with 1500 children (8 and 13 years of age) and their mothers. They responded to questionnaires on monitoring knowledge, sources of maternal information (maternal solicitation and/or child disclosure), and demographic variables. Data were analyzed by Pearson's r, ANOVA, and regression analysis. Mothers' knowledge of her child's activities and whereabouts and the sources of her knowledge were associated with mothers' higher level of education. Child's age was related to mother's knowledge and maternal solicitation. Maternal solicitation and child's age were highly predictive of mothers' knowledge of her child's whereabouts and activities. Results of this study may have applications for parental supervision and child rearing attitudes.

Rearing temperature influences food consumption, conversion and cocoon production in silkworm Bombyx mori L. Young age $({1^st}to{3^rd} instar)$ worms of Pure Mysore, a multivoltine were reared at 26, 28, 30 and $32^{\circ}C$ followed by combinations of these temperature levels during late age $({4^th} and {5^th} instar)$. Food consumption, conversion, larval duration and growth for each instar were recorded. The influence of combinations of these temperature levels during rearing on survival and cocoon production was assessed. Food consumption increased with the temperature up to $4^th$ instar and decreased during $5^th$ instar. Temperature beyond $28^{\circ}C$ during young age followed by higher temperature ($30^{\circ}C$ and above) has shown deleterious effect on cocoon production. The paper discusses the rearing performance in relation to food intake and conversion under the tested temperature levels.

The purposes of this study were to investigate the difference of maternal parenting stress and social support according to infant's age and to examine the effect of social support and infant's age on parenting stress. The subjects were 145 mothers who have 2-5 olds children. The questionnaire was used as a methodological instrument and the statistics used for data analysis were frequency percentile mean t-test Pearson's r-coefficient and multiple regression. Results of this study indicate that mothers with 2-3 olds child perceived more child's demandingness and mothers with 4-5 olds child perceived more mother's competence. Mothers with 2-3 olds child perceived more social support than mothers with 4-5 olds child. Husbahd's support and infant's age were found to be important variables in predicting parenting stress.

The purposes of this study were 1) to determine the relationship between antigravity control(supine flexion and prone extension) and postural control(static and dynamic balance) by age, 2) to determine the quality of antigravity and postural control, and 3) to determine whether sex difference correlates with differences in antigravity and postural control in young normal children. We tested 120 children aged 4 to 7 years. The study results showed a significant relationship between antigravity and postural control by age. Quality scale measurements(r=0.90) indicated that the children in this study had not yet developed full antigravity or postural control. The study results revealed differences between sexes(f>m in 5 of 7 tests) and a significant relationship by age in antigravity and postural control.

A comprehensive study on daily pupal weight loss due to histolysis and histgenesis in Bombyx mori Linn., has been undertaken. The percentag of pupal weight loss in the male pupa is higher than the female, conforming that the female pupa require more energy in the form of less pupal weight loss for ovipositional activities. The regression equation clearly shows higher percentage loss of daily pupal weight in male than female with respect to age and, this is also evident from the slope of the regression line. Moreover, analysis of the coefficient of correlation shows that the weight loss of pupa is directly correlated with the age rather than climatic parameters under which the pupa dwells.

Objectives: Working at other times than the regular day shift has been reported to be a stressor associated with health consequences and mental disorders as well as disturbance of sleep. In current study, we aimed at investigating the relationship between work schedule, sleep quality and depression among police officers. Methods: Eleven hundreds and forty five police officers (male: 1040, female: 105) completed questionnaires of basic socio-demographic data, Pittsburgh Sleep Quality Index (PSQI), Korean Scale of Occupational Stress (KOSS), Impact of Event Scale - Revised (IES-R) and Center for Epidemiologic Study-Depression (CES-D). Results: After controlling for age, sex and educational level, score of CES-D was correlated positively with the score of KOSS, PSQI and IES-R on partial correlation analysis (r=-0.077; p=0.009, r=0.262; p<0.000 and r=0.421, p<0.000, respectively). Logistic regression analysis revealed that female sex, age, the score of KOSS and IES-R and schedule of rotating shift work predicted higher score than 16 score of CES-D significantly in total subjects (p=0.023, p=0.015, p=0.000, p=0.000 and p=0.022, respectively). Conclusion: Current result suggested that not only female sex, age, higher occupational stress and impact of event scale but also rotating shift work schedule might be related to depression among police officers.

This is a cross-sectional study to evaluate the serum lipid levels of children living in Pusan in 1996. The distribution of age is from 2 years old to 12 years old. In female children mean total cholesterol is $171.4{\pm}26.2mg/dl$, triglyceride is $104.7{\pm}50.6mg/dl$, HDL-cholesterol is $54.4{\pm}14.8mg/dl$, and LDL-cholesterol is $95.4{\pm}32.9mg/dl$. In male children mean total cholesterol is $167.9{\pm}25.2mg/dl$, triglyceride is $6{\pm}45.5mg/dl$, HDL-cholesterol is $55.4{\pm}11.7mg/dl$, and LDL-cholesterol is $94.4{\pm}23.6mg/dl$. The percentile of serum lipid levels is measured in children. The 95th percentile of serum total cholesterol is 210mg/d1 in male children, and 214mg/d1 in female children. And, the 95th percentile of serum triglyceride is 184mg/d1 in male children, and 191mg/d1 in female children. And, the 95th percentile of LDL-cholesterol is 133mg/d1 in male children, and 135mg/d1 in female children. Serum total cholesterol is positively .Elated to age(r=0.18), height(r=0.08), weight (r=0.17), obesity index(r=0.12), and negatively .elated to father's education level (r=-0.13), mother's education level(r=-0.13). Serum triglyceride is positively related to weight(r=0.23), age(r=0.31) and negatively .elated to father's education level(r=-0.12), mother's education level(r=-0.18). Serum HDL-C was positively reated to mother's education level(r=0.07) and negatively .elated to height(r=-0.12), weight(r=-0.09). Conclusively, the serum lipid levels of children living in Pusan is generally so high that the family and school must try to control the serum lipid levels.

In this paper, we propose the basic data for cancer patient management by secondary analysis of data from the National Health and Nutrition Survey(KNHANES) to identify factors related to suicidal thinking of cancer patients over 19 years of age in Korean adults lapse of time. The data were analyzed using the IBM SPSS WIN 22.0 program in order to analyze the demographic, health, and mental characteristics of the subjects in 2009 and 2017. It was analyzed using logistic regression analysis. As a result of the study, the factors related to suicidal thinking in cancer patients were activity restriction and experience of depression in 2009(Negelkerke R²=.384), and age, marital status, activity restriction, and experience of depression in 2017(Negelkerke R²=.525). This study is meaningful in that the factors related to suicidal thoughts in cancer patients were identified according to the lapse of time, and the changes in the related factors were confirmed. Development and application of an intervention program to prevent suicide in cancer patients are necessary.

This descriptive study was designed to find out the relation between self concept and ethical concept of nurses. The data were collected from 224 staff nurses in a tertiary hospital located in Suwon city during February 24 to March 7, 2001. Self concept was measured with questionnaire developed by chung (1965) and ethical concept was measured with the questionnaire developed by the researcher. The 5 point Likert scale questionnaire had 95 items. The results were summarized as follows: 1) The mean score of self concept was 3.11. The ethical concept were measured in 4 areas and mean scores were : accountability, 3,93; collaboration, 3.70; caring, 3.63; an advocacy, 3.15. So accountability was the area with the highest score in ethical concept. 2) Nurses' self concept was significantly related to ethical concept (collaboration, r=.34, p<.001; advocacy, r=.32, p<.001; caring, r=.28, p<.001; and responsibility, r=.23, p<.001). 3) The self concept was significant in age(F=3.28, p=.000) and the ethical concept was significant in age(F=15.88, p=.000), education level(t=2.16, p=0.03), career(F=5.16, p=.001) In conclusion, there was a significant relationship between self concept and ethical concept of nurses. High score in accountability may be related to high level of legal responsibility of nurses. This finding suggests that it is the length of nursing career is significantly related to both self-concept and ethical concept. Thus, it is important to improve self concept in order to improve ethical concept of nurses from early the beginning of their career.
