This study evaluated the types of daily routines that occurred in child care centers based on four general categorizations: time spent on indoor free choice activities, outdoor activities, group activities and special activities. In addition, resulting child care teacher behaviors were examined based on daily routine types. A total 23 classes' activity times and teacher behaviors were observed. The collected data were analyzed using descriptive statistics, hierarchical cluster, and Mann-Whitney U. Results indicated that there were 2 principle daily routine, 'indoor/outdoor activity time oriented' and 'group activity time oriented'. Analysis showed that teachers who belonged to the 'indoor/outdoor activity time oriented' type showed more positive affect, positive guidance, neural guidance, and less non-involved behavior. Results suggest the importance of time spent on free choice activities in the context of daily routine for quality childcare.

The purpose of this study was to provide the basic data needed for developing comprehensive child edu-care programs that fits the regional needs. Subjects of the survey were the teachers of child edu-care centers in Daejeon. 95 teachers were selected from 20 child edu-care centers, using stratified random sampling method, from all of five municipal districts of the city. Gathered data were analyzed using SPSS 10.0 for reliability, factor analysis, frequency and percentile, mean, standard deviation, paired samples t-test and F-test. The summary of the findings were as follows: First, the result of survey on the child edu-care facts showed that the most child edu-care centers had the focus on caring and education programs of children, while emotional supports for family services and community social services were rather secondary importance. Therefore, to achieve the comprehensive service programs, child edu-care services should be harmonized by the education and welfare approaches. Second, centered around teacher's request, comprehensive child edu-care program that fits the regional characteristics focuses on family service; thus the program requires family group consulting, parents education etc., as well as focusing on community service to utilize local community's human, physical resources and to strengthen the tie between local community and child care services.

For the development of more effective insecticides for aphids, including the cotton aphid, Aphis gossypii Glover, control released insecticides were developed and tested as new type of formulation for the cotton aphid. Etofenprox is a target-of-control-released formulation that is toxic to insects with piercing-sucking type mouths including aphids and hoppers. The insecticidal effect of etofenprox is distinguished among others; however, continuance period of the effect of insecticide is shorter than other insecticides. In addition, the control effect of control released etofenprox on the cotton aphid was examined. The results show that control released etofenprox induced no control effects to the cotton aphid within 5 days of treatment. The cotton aphid's population was increased, and their reproduction rate was also high. However, control effect was shown to have very low levels 7 days after treatment, and it increased to higher effect. It is supposed that it is possible to control the cotton aphid using the type of control released etofenprox with a kitosan carrier. It is necessary to develop a more effective carrier type to release more of the insecticidal ingredient on the leaf after spraying.

Biological control of aphids using "banker-plants with the parasitoiid, Aphidius colemani Viereck (BPAC)" was carried out on cucumber in greenhouse. The BPAC consisting of barley seedlings infested with Schiraphis graminum (Rondani) enhanced the early establishment of Aphidius colemani in the greenhouse and prolonged the control of Aphis gossypii on May 8, 2001 The BPAC was placed in the greenhouse at transplanting at the rate of 1 per 30 m2 of cucumber. Although good control effect was gained until early August after placing banker plants on May 9, the effect after then because of high temperature. The aphid population on cucumber in control plots reached to a peak on June 26, and decreased because of entomopathogenic fungus for rainy season of July, and increased again to a very high population on August.

The purpose of this study was to examine different child care curricula according to teacher's teaching method types. The subjects of the study were three hundred and fifty-six teachers, who were divided into four groups according to their teaching method: mixed method(type A), child oriented method(type B), teacher oriented method(type C), and beliefless method(type D). The data on the duration of free play and outdoor play time, activities frequently practiced in class, and outside one the playground were collected. The dimensions of child care programs were measured using Moore(1994)'s "The Early Childhood Dimensions of Education Rating Scale". The results of this study were as follows: first, teachers who used child oriented teaching methods gave more free play time than teachers using teacher oriented or mixed teaching methods. Second, teachers using teacher oriented methods showed the closeness and teachers using child oriented methods showed the openness in child care programs. Last, the activities teachers thought were the most important differed according to the teachers' methods even though in actual practice, there was no difference shown.

This study has been carried out for the antimicrobial effects of organic silicon quaternary ammonium salt with which cotton, polyester, and wool were treated respectively, using Esherichia coli and Proteus bulgaris which are experimental bacteria for clothing materials. As a results, the best antimicrobial effects of organic silicon quaternary ammonium salt came out from cotton ; the next form wool ; and lower from polyester. With the changes of the temperature, the antimicrobial effect with soaking time, there was no changes with cotton after 10 minutes passed. It seemed to have reacted entirely in the early stage. The longer the soaking duration was, the higher the effect from polyester was. The effect from wool was increased until 20 minutes, but decreased after 30 minutes. The optimal processing condition of cotton was in the condition of liquor ratio 40:1, concentration 0.5%, soaking time 5 minutes, and temperature 3$0^{\circ}C$ ; wool was 1.5%, 20 minutes, and 6$0^{\circ}C$ ; polyester was 2.0%, 30 minutes, and 3$0^{\circ}C$ respectively. The changes of the effect by washing was as followings : The processing effect on cotton and wool appeared to be everlasting, since they had no changes by washing 10 times ; while, it was remarkablely decreased with polyester by washing only once, and was almost disappeared after washing 10 times, which means that polyester has no durability to washing.
