In order to search for the anti-HIV agents from natural products, eighty MeOH extracts of medicinal plants were applied to a syncytia formation inhibition assay which is based on the interaction between the HIV-1 envelope glycoprotein gp120/gp41 and the cellular membrane protein CD4 of T lymphocytes. Among them, Ailanthus altissima showed a potent virus-cell fusion inhibitory activity. Repeated column chromatoghaphy of the methylene chloride fraction of A. altissima afforded compounds 1$({\beta}-sitosterol-3-O-{\beta}-D-glucoside)$, 2(tetramethoxycoumarin), and 3(ocotillone). Virus-cell fusion inhibitory activity of compound 3(ocotillone) was $70.76{\pm}4.09%$ at the concentration of $100\;{\mu}g/ml$.

Knock phenomenon is an abnormal combustion originated from autoignition of unburned gas in the end-gas region during the later stage of combustion process and it accompanys a high pitched metallic noise. Engine Knock is accompanied with a vibration of engine cylinder and when it is severe, it can cause major engine demage. Engine Knock is characterized in terms of knock crank angle, knock pressure, pressure jump and knock intensity. In this study, a 4-cylinder spark ignition engine was used for experiment and eighty consecutive cycles were analyzed statistically. The purpose of this study is to characterize spark ignition engine knock as a function of ignition timing and fuel research octane number. The result of this study can be summerized as follows. Knock occurrence angle approached TDC as ignition timing is advanced. Pressure and knock intensity gradually increased as spark timing is advanced. Mean knock occurence angle gradually approached TDC as fuel research octane number is decreased for identical spark timing. Knock intensity increased linearly as RON is decreased.

This study aims to evaluate the degree of malnutrition of children by three nutritional indicators-Weight for Age, Hight for Age, Weight for Height. The results are as follows; The average height and weight of children are much lower than Korea average height and weight. In terms of Weigh for Age, 20-40% of the samples belongs to below-2 standard deviation from the mean of reference group. 90% of the samples falls into the region below the mean. The standard deviation score indicates negative sign for eighty to ninety percent of the samples. The malnutrition of the samples is also confirmed in terms of Height for Age. In terms of Weight for Height, the mean of the samples is not significantly different from that of the reference group. Tests of the nutritional status under basis of three nutritional indicators show that approximately 50% of the samples had suffered from malnutrition and 17% of the samples have suffered from malnutrition.

The purpose of this study is to investigate the attitude of housewives towards the elderly people. Three hundred and eighty-one housewives were selected, and a set of questionnaire was used to collect data. The Instrument for this study consisted of 20 item semantic differential format. The results are as follows: Housewives hold a slightly negative attitude towards the old. The main reasons for that were significantly different according to their educational level, religion, economic level, and marital satisfaction. By using a cluster analysis, the housewives could be divided into four groups. Among them, a group with positive attitudes towards the old had an experience living with parents. Based on the results of this study, it is revealed that the data on the attitudes of housewives towards the elderly will offer valuable information in developing education programs to change their negative attitudes.

Purpose: This study was done to examine the relationship between self-reported attachment style, trait anger and anger expression in adolescent women. Method: Five hundred and eighty adolescent women were recruited from March to May, 2006. The instruments were Spielberger's state-trait anger expression inventory-Korean version (Chon, Han, Lee, & Spilelberger, 1997), and Batholomew & Holowitz's attachment style Questionnaire (1991). Data was analyzed by descriptive statistics, and ANOVA using the pc-SPSS (version 10.0) program. Result: The mean score of trait anger and anger-in were higher in adolescent women with an insecure attachment style compared to women with a secure attachment style. Conclusion: This finding suggests that family environment factors such as attachment styles are related to trait anger and anger expression in adolescent women. There is a need to further clarify the relationship of attachment style, trait anger and anger expression in adolescent men.

One thousand and eighty eggs of Japanese quail (Coturnix coturnix Japonica) were set into the incubator maintaining 36 treatment groups (3 egg weight groups ${\times}3$ seasons ${\times}4$ preincubation holding periods) to evaluate their hatchability performances. Holding periods had significant (p<0.05) effect on hatchability and the seasons showed significant (p<0.05) effect on chick weight. All the parameters (except fertility) were significantly (p<0.01) influenced by the egg weight. None of the parameters maintained regular trend with egg weight and pre-incubation holding periods. Significant interactions were not observed on any of the parameters (except fertility) studied. The egg weight maintained significant (p<0.05) negative correlation with fertility and positive correlation with chick weight. Eggs of medium weight (9.10 to 10.00 cm) could be hatched satisfactorily between 4 and 7 days of pre-incubation holding periods in any season of the year.

This study was conducted to investigate the relationship of serum calcium and magnesium levels to depression and anxiety symptoms in 80 homemarker. Fasting blood samples were collected and serum calcium and magnesium concentrations were measured. At the same time, psychological conditions of subjects were estimated by questionnaire. As the result of psychological test, eighty homemarkers were divided into two groups according to psychologicaltest scores. The subjects in one group got high pssycholgoical test scores as high score group (HSG) and the others got low physchological test scores as low score group(LSG). Serum calcium and magnesium concentrations were significantly(p<0.05) lower in HSG than in HSG than in LSG. Many a subject who belonged to HSG appeared to have depression and anxiety symptoms. Drepression and anxiety scores of the subjects with calcium supplementation were significantly (p<0.05) lower than those without calcium supplementation . After calcium supplementation, depressiion and anxiety scores were significantly (p<0.05) decreased in HSG and serum calcium and magnesium concentrations in HSG were significantly increased to normal ranges . This results suggested that psychological conditions of homemarkers might be affected by serum calcium and magnesium levels.
