This study was conducted to investigate the differences in environmental and psychological factors in children with obesity and to offer useful information for obesity treatment and prevention. 123 children of 5-6th grade in elementary school and their mothers were included in this study and divided into either the obese group and normal group(obese group: 61, normal group: 62) according to the Weight-Length Index(WLI). Results showed that between the two groups there no significant differences in family income, mother's occupation status, educational level, and anthropometric measurement. Nutritional knowledge in the obese group was significantly higher than that of the normal group(p<0.05). The mothers of children with obesity had a higher level of nutritional knowledge than the mothers of normal children(p<0.05). There were no significant differences in food behavior between the obese and normal groups. There were no significant differences in maternal child-rearing practices and in maternal attitude on flood behavior of children. Considering psychological factors ; 72.1% of the children with obesity appraised their body image as obese(p<0.05), and 54.1% of the mothers in obese group perceived their child's body shape as obese(p<0.05). The level of self-esteem were not significantly different when compared between the obese and normal groups. From these results, it was suggested that effective measures for obesity treatment and prevention should include nutritional monitoring, and such efforts need to be maintained in order to help the obese children and their mothers.

The purpose of this study is to find out the effect of recovery from psychological stress when watching plants indoors. As an instrument of measurement of psychological stress, Galvanic Skin Resistance(GSR) has been used because it has been convenient to read a psychological sign without a medical sense and an instrument. In order to make the conditions of stress and recovery, video programs have been made, and especially, the video program of recovery has consisted of three types-- types 1 of watching plants in a botanical garden, type 2 of watching very bush street, and type 3 of closing eyes naturally. The two groups of normal and the mentally handicapped persons have been participated in this experiment to compare the effect of recovery. As the result of this test, the rate of stress relief has been maximumly effected by watching the video program of plants. Between the two groups the recovery of stress has had better effects on the mentally handicapped than the normal one. And also it shows that the circumstances of emotional refinement is led by having plants in indoor. The result of this test has been turned out to be highly useful. It is desirable that a indoor worker, staying for a long time, contact with plants visually to keep healthy mental conditions. This study suggests that the surrounding conditions or the settings of circumstances play an important role for the emotional refinement of the groups of mentally han야capped persons as well as the normal person.

The Ministry of Education in Saudi Arabia encourages Saudi students to continue their education at Saudi universities or abroad. Currently, an estimated 1,282,140 Saudi students are studying at Saudi universities. The extent of the research so far has not focused on Saudi student experiences, but it has shown that even a single negative event can dramatically reduce the chances of a student completing a degree. Thus, more research is necessary to identify and describe the context and obstacles (environmental and psychological) that Saudi students face. The evaluation was multifaceted to capture not only performance outcomes, but also other factors that have been suggested by research as influential to students' ability, such as the environmental, cultural, and psychological risks for graduation that Saudi students self-report. A single group pretest (survey) design was used in this study. Findings suggest depression stress and college stress predict stress levels, while subjective happiness predicts levels of scientific participations of the sample. Moreover, depression stress shows more consistency with hours spent on the internet for study purposes. These results should be considered in study support programs both institutionally and geopolitically by universities and governments.

This study was undertaken to develop an instrument to be used for measuring the concept of quality of life of Korean patients with cancer multidimensionary and correctly. It can contribute in holistic nursing care for Korean cancer patients and also provide and validate basic data to help oncology nurses measure the outcome of nursing intervention correctly. To develop this instrument, the researchers first estabilished a conceptual framework based on the results of qualitative data analysis and indepth interview method Development of the scale was conducted using a method in which 31 items were assessed by subjects' self report using linear analogue scales. The subjects were 79 D.M. patients, 103 patients with acute illness, and 91 cancer patients residing in Busan, Korea. Data were collected during the period from July, 24 to August 14, 2000. This instrument consisted of 31 items with a self report scale. This instrument covered 4 dimensions of cancer patients : 1) physical wellbeing 2) psychological wellbeing 3) social wellbeing and 4)spiritual wellbeing. Each item had a possible score of 10. The reliability of the scale was tested with Cronbach's alpha. Validity was evaluated by examining the relationships of this scale, Youn's Quality of Life Questionnare scores and the Simple Quality of Life scale. Two separate runs of multiple regression were used to predict scores on the Simple Quality of Life measurement. Further validation was obtained by examining the correlation between the instrument subscores and Youn's Quality of Life measurement subscore for convergence of this scale. Examination of the discriminant. power of the instrument was done using ANOVA test. The results are summarized as follows: 1. The reliability of the instrument for the quality of life was 0.8321(Cronbach's alpha.), physical wellbeing dimension 0.6343, psychological wellbeing dimension 0.6501, spiritual wellbeing dimension 0.5883. 2. This instrument had a high correlation with Youn's Quality of Life measurement(r= 0.636) in cancer patients, whereas it had a low correlation with Simple Quality of Life measurement(r=0.455) in cancer patients. In the D.M. patients, the instrument correlated with both the Youn's Quality of Life measurement and Simple Quality of life measurement(r=0.313, r= 0.407) and in the acute stage patients, the instrument had no correlation. 3. Multiple regression of individual items on the Simple Quality of Life scores accounted for 56.8% of the variance in the Simple Quality of Life measurement, whereas, Youn's Quality of Life measurement scores accounts for 31.7%. 4. The correlations collected from the three group had the same patterns of variations but especially the instrument developed in this study had higher disciminant power than that of Youn's Quality of Life Measurement.
