  • This study develops a prediction model for toilet and laundry water end-uses based on surveyed data which measured housing and household characteristics of 140 households over 5 years in Korea. Classical regression model assuming a normal distribution was not appropriate and estimated parameters were biased, because the distribution of measured water-uses was left-skewed. As an alternative to this problem, we considered the distribution of weibull and lognormal for each water-uses, and three regression models were compared using log-likelihood and scale parameter. As a result, weibull regression were chosen to be appropriate for both water-uses and also presented the factors that affect each water-use. This results expect that an insight is provided on water resources utilization and theoretical support role for effective water resource management.

  • The study was first part of the research on development of consumer education program as social education program. The purpose of this study was to review social consumer education programs conducted by various organizations and to examine the consulting statistics from Korea Consumer Protection Board and Korea National Council of Consumer Organizations. In Consumer Protection Board, consumer education was operated mainly for both college students majored in consumer studies and public-sector workers. Outgoing education was provided mainly to the persons in industries and housewives. Other consumer organizations conducted consumer education using government funds. The organizations considered 'purchasing' and 'consumerism' most frequently as the topics for the education. 'Credit' and 'insurance' were another main concerns at the education. The consulting statistics showed that 'mobile communication', 'laundry service', 'health foods', and 'educational materials for foreign language' took the largest portion of the consumer consulting. Some implications were made for developing consumer education program as social education.

  • Recently, with a growing interest of health and environment, chitosan which was good in no harmful effect to human body and environment, has been watched as the finish treatment of hygiene and pleasantness. The purpose of this study is to develop multifunctional fabric that was improved antimicrobial activity and deodorization rate, water absorption, static voltage and dye absorption by treatment of nylon 6 grafted with acrylic acid added in chitosan. FT-IR spectra of the grafted with acrylic acid added in chitosan shows peaks of COOH and NH2. Antimicrobial activity and deodorization rate of chitosan and grafted with acrylic acid added in chitosan were increased greatly than the control, durability of laundry of grafted with acrylic acid added in chitosan was good. In case of chitosan was dyed acid dyes and grafted with acrylic acid added in chitosan was dyed basic dyes, dye absorption of them were increased than the control. Moisture regain, absorption time and tensile strength of grafted with acrylic acid added in chitosan was increased greatly than the control.

  • The purpose of this study was to investigate the implementing level of housewife's manage-ment behavior related to reducing environmental pollution and the effects of three variable-groups on management behavior related to reducing environmental pollution. The research data were collected by structured questionnare and 544 cases were finnally selected. The data analysis was conducted by the method of frequency mean Pearson's correla-tion multiple regression. The major findings were as follows: 1) The implementing level of housewife's overall management behavior slightly high. 2) Wife's value(ecologicalism materialism expediency social-enviromental resources(degree of masscom contact degree of meeting with neighbors. refuse box) were significant predictors of the level of overall management behavior And Background variables(wife's aged and educa-tion level & job household income occupation of husband) had not significant effect on the level of overall management behavior. The most influential variable-group on the level of overall management behavior and buying cleaning & dishwashing cooking laundry activities was Wife's value. But the most influential variable-group on the implementing level of disposing trash was social-environmental resources.

  • The purpose of this paper was to identify bonding strength by weave (plain weave, twill weave, satin weave) and counts(20 s, 40s) of the face cloth cotton 100% in the course of sewing process using by cotton fabric of adhesive interlining. The results of the study was as follows. 1. With the increased laundry, it revealed that the bonding strength was decreased to some degree regardless of the kinds of face cloth. 2. the bonding strength by the counts of the face cloth appeared in order of 40 s<20 s. 4. It was observed that there are no significant differences on the adhesive strength in the cutting directions which are an inclination warp, weft, bias in this experiment.

  • Since the diffusion rate of sewage treatment plant is about 30% of the country. It is not enough to cope with entire sewage treatment of the community. Therefore, the septic tank is introduced which is connected with water flush toilet only. It is estimated that the large portion of water pollution has occured due to untreated sewage such as pollutants of kitchen, laundry and bathtub water, etc., which are not go through the existing septic tank. However, the construction of community plant which is could treat most of household run sewage should have flexibility in type, treatment method, effectiveness and economy which are adoption of the community. Without the treatment of combined household run sewage, the improvement of water pollution will be hardly expected.

  • The dyeability and colorfastness of browning extracts from mushroom were investigated. The results of this study are as follows, 1. Browning extracts from mushroom exhibited dyeability to wool, nylon and silk. The wool and silk had the greatest K/S value at pH 4 and nylon at pH 5 2. Furthermore, the increase in K/S value corresponded to temperature, time, and the number of dyeing. 3. In most cases, the value of K/S was increased by mordant treatment. The treatment of pre-mordant caused the increase in K/S value depending on the concentration of mordant, but not in the color. Co.mordant and post-mordant treaments, however, showed various colors of YR, Y, and GY types of Munsell color wheel. 4. In the most cases, color fastness of light, drycleaning, laundry, sweat, rubbing was excellent.
