Effects of spraying of machine oil emulsim on occurrence of tea red spider mite. Tetranychus kanzawai and yield of first tea were evaluated. The results were summarized as follows : 1. Occurrence of tea red spider mite moved from basal part of harvest surface of east in February. to middle and top part of harvest surface. 2. The population density of tea red spider mite was high on expanded upper second leaves(38%) and upper first leaves(29.2%). Horever, the density of tea red spider mite on unexpanded leaves and basal leaves was low. 3. Control value of machine oil emulsion applied on 15 March was 45%, but was 36.3% at routine application of 15 February. Two applications on 15 February and 15 march was betler than one application against tea red spider mite. 4. Control value of machine oil emulsion diluted to 20 to 40 times was 42.5~50%, but was getting lower at dilution of 60 to 80 times. The yield of fresh leaves of application at dilntion of 20 to 40 times was increased 6~7% than that of 80 times. 290kg/10a. 5. Phytotoxicity was detected with slitht wilting when machine oil tmulsin was applied at dilu tion of 20 times. However, there was on phttotoxicity in the other trials.

Purpose: The purpose of this study was to determine the sexual knowledge, and sex education perception and current status of the parents of preschoolers. The objective was to analyze the relationship between sexual knowledge and sex education demands of parents. Method: The method used in this study was a descriptive correlationstudy. The subjects were 278 parents of 3-to-6 year old children in 5 kindergartens located in Seoul. Data were analyzed using frequency, percentage, average, standard deviation, t-test, ANOVA, Scheffe test, and correlation using the SPSS 20.0 program. Result: The results of this study were the following: 1.There was no significantdifference in the sexual knowledge between the father and mother of preschoolers (Father 20.76, Mother 20.73). According to the findings, sexual knowledge was higher when both father and mother were older (P=.005). Similarly, when the economic level of the father and mother was high, sexual knowledge was also high (P=.030). 2.Concerning sexual education perception, it was found out that both father and mother thought that sex education was necessary. 3.In terms of sex education, a significant difference was noted. Mothers conducted sex education more often than fathers (Fathers, 46.7% Mother, 60.3%). Both the father and mother thought that providing sex education would be best in Grades 1-2, especially for ages 6-7. 4.When asked about the demands for sex education in terms of the physical, social, and living aspects, living aspect was the highest demand. It was revealed that both fathers and mothers were aware of the need for sex education, and when parents hadmore sexual knowledge, they would demand more sex education. Accordingly, there was a correlation between parent’s sexual knowledge and demand for sex education (r=.202, p=.001). Conclusion: Since the age,knowledge, education and economic levels of parents were different, it was necessary to develop sexeducation programs in accordance with their levels. In this way, preschooler parents would be able to teach sex education appropriate to their children’s level.
