The purpose of this study was to analyze effects of the mother's child-rearing patterns on children's academic achievement with respects to ‘understanding of family and work’ area in Practical Arts Education related to the 7th revision on the Curriculum of the Elementary School. The questionnaire was used for the survey. The subjects were 200 mother-child (total of 400) randomly chosen from 4 elementary schools in Seoul. Data were analyzed by frequencies, percentages, averages, standard deviations, Pearson's correlation coefficients, t-tests and one-way ANOVA's using the SPSS/PC＋ program. The results of this study were summarized as follows : The correlation between income in their home and their children's academic achievement did not analyze because of the omitting record in their questionnaire. The relations between the patterns of mother's child-rearing and children's academic achievement by children's sex and by grade were examined. But in this study, these relations scarcely have significant differences between the children's academic achievement and their mothers' child-rearing pattern except between being significant reject-sanctions type of mothers' child-rearing and the children's academic achievement. However, the child-rearing patterns of mothers which children and their mothers think were similar, then the high correlations were found between their patterns.

Decrease in the cocoon production of Japan is drastic because of low price of cocoon, scarcity of successors and so on. To tide over the difficulty, the automation system in the sericulture was discussed and some trials have been conducted by the Ministry of Agriculture, Forestry and Fisheries of Japan. The attempts are based on a low cost artificial diet which does not rely on mulberry leaves. Automatic machines developed until now are a rearing machine constituted with repeated belt conveyor, an reformation type of former rearing machine "Bombyx" and a mounting machine. Running parallel with them, utilization of 20-hydroxyecdysone extracted from a plant to the mounting was also studied to use their machines efficiently in the fields. In conclusion, 10 tons of law cocoon will come to be produced by two persons labor. At present, an automatic rearing system on low cost artificial diet has been developing for the future sericulture.

본 연구의 목적은 청소년이 지각한 부모의 양육태도와 의사소통이 진로의사결정유형에 어떠한 영향을 미치는가를 검증하여, 자녀들의 합리적 진로의사결정을 위해 바람직한 어머니의 양육태도와 아버지의 의사소통유형을 제시하는데 있다. 본 연구결과 청소년 자녀들이 어머니에 대한 양육태도를 수용적으로 인식할 때, 진로의사결정을 합리적인 방향으로 더 나아가며, 어머니에 대한 양육태도를 거부적으로 인식할 때 진로의사결정을 의존적인 방향으로 한다는 것을 알 수 있다. 아버지의 개방형 의사소통은 청소년 자녀들이 합리적 진로의사결정을 하는데 통계적으로 유의한 영향을 미쳤으며, 아버지의 문제형 의사소통은 청소년 자녀들이 의존적 진로의사결정을 하는데 통계적으로 유의한 영향을 미치는 것으로 밝혀졌다.

Silkworm body and rearing seat disinfection is an integral part of effective silkworm rearing as it prevents the spread of various diseases through secondary contamination in the rearing bed. Many bed disinfectants are recommended by various research institutes in India. In the present study, eight bed disinfectants viz., Vijetha, Labex, Resham Jyothi, Sanjeevini, Suraksha, Reshamkeet Oushadh, Dithane M45 and Captan recommended by various Sericultural Research Institutions in the country against the spread of common diseases of silkworm were tested to determine their comparative efficacy. For the study, all the treatment batches were introduced with fixed number of specific diseased larvae so as to maintain a constant source of pathogen in the bed and then followed by treatment with respective bed disinfectants. Percent mortality/infection due to each disease was recorded to determine efficacy of bed disinfectant treatment against respective disease. The results show that all the bed disinfectants tested have considerable efficacy against the spread of various diseases in the rearing bed. However, Vijetha was distinctly superior in its efficacy against all four major diseases of silkworm. The study emphasize the role of bed disinfectants in silkworm rearing and the fact that they should be judiciously selected based on the efficacy of the bed disinfectant and the type of disease prevalent in a particular season and area.

본 연구는 자녀의 영재성 개발에 영향을 미치는 부모의 성격유형과 양육태도에 있어 영재아와 일반아 부모들의 그것에 있어 어떤 특성과 어떠한 차이가 있는가를 파악하기 위해 초등학교 4$\sim$6학년 영재학생 어머니 85명과 일반학생 어머니 101명 등 총 186명을 대상으로 MBTI검사와 양육태도검사를 실시하였다. 연구 결과 첫째, 영재아 어머니들은 일반아 어머니들에 비해서 내향적인 성격을 띠고 있는 반면, 일반아의 어머니들은 영재아의 어머니들에 비해서 의향적인 성격을 지니고 있었다. 또한, 영재아 어머니들은 일반아 어머니들보다 직관적, 판단형적인 성격을 지니고 있는 반면, 일반아의 어머니들은 보다 인식형적인 성격을 지니고 있었다. 둘째, 영재아 어머니들은 일반아 어머니들에 비해서 보다 더 수용적이고 자율적인 태도를 보이고 있는 반면, 일반아 어머니들은 보다 더 거부적이고 통제적인 양육태도를 보이고 있었다.

The suitability of a flexible fiber filter for removing suspended solid (SS) in a recirculating aquaculture system was evaluated. This study focused on variation in the performance with a change in filtering time, influent water quality, and filtering mode duration. The particle distribution diagram of the filter effluent showed that the number of particles bigger than $5-8{\mu}m$ decreased dramatically, and the removal efficiency exceeded 80%. Although the removal efficiencies of SS and chemical oxygen demand (COD) were dependent on the quality of the influent, the SS and COD concentrations of the effluent were not affected by the influent concentrations. This was despite the deterioration if water quality after feeding in the rearing tank. The performance of the filter was not affected by the filtering mode duration, feeding conditions, or filtering time. The SS concentration and turbidity of the recirculating-type rearing tank were 30% and 50% lower, respectively, than of the a non-recirculating-type rearing tank under the same operating conditions. The flexible fiber filter was applicable to a recirculating aquaculture system that uses plenty of seawater, based on its low filtering resistance $(2kg_f/cm^2)$, high flux $(330m^3/m^2/hr)$, and high fine particle removal efficiency (80%, $5-8{\mu}m$).

This study was conducted to investigate the actual conditions on housing and facilities for goat. This investigation of the actual conditions was investigated by the style of farm which was divided into sideline scale and speciality scale included 47 farms. The results are summarized as follows: Rearing scale was 48.9% for 50-100 heads per farm. Rearing type was 46.8% for grazing type and 53.2% for barn type. Housing type was 27.7% for simple frame housing and 72.3% for permanent housing. Pipe was used 80.8% with Pillar and Girder as the housing frame at farm. For the pipe used in farm, 27.7% of them was used for simple frame housing. Side wall was composed of cement and winch curtain to be 29.8%, slate roof to be 40.4%, pipe partition to be 38.3%, and cement floor to be 51.1%.

This study investigates the relationship between a mother's self-differentiation and the rearing reviews focused on the mediating effect for the early adjustment of 1 to 2 years old at a nursery. First, the results based on the difference between the child-rearing attitudes of the level of self-differentiation show significance in the affectional-autonomic attitude in the top quarter of the total level of self-differentiation. Second, the level of the self-differentiation depends on the early adjustment results from the significant differences in the sub-elements; except for the emotional fusion that results in the higher the level of mother's self-differentiation that leads to higher early adjustment. Third, the impact of affectional-autonomic and affectional-controlling attitude reflected the positive influence of the entire early adjustment based on the effect of the child-rearing attitude. Finally, the results on whether the mothers' parenting attitudes influences the self-differentiation and the transition of the infant would mediate the early adjustment-relationship as shown in the mediating effect of parenting attitudes. Each type of mediation effect showed an affectional-autonomic and affectional-controlling attitude. In this study, the mother's self-differentiation and the infant nursery process shows the early adjustment associated with variables, the mother's level of self-differentiation, and the parenting attitude that effects the early adjustment that examined the mediation effect in the relations of self-differentiation and the early adjustment of child-rearing attitudes.
