This study is to optimize the conditions for the treatment of polyamide fabrics using laccase. The pH, temperature, treatment time, and concentration were varied; their effects were evaluated by measuring the number of primary amide groups by the uptake of an acid dye measured by K/S of dyed polyamide fibers. The hydrophilicity of the fabrics was evaluated in terms of moisture regain and wettability. The effects of the mediator, ABTS, on the laccase activity were also evaluated. The optimal treatment conditions were identified as a pH of 4.5, temperature of 30oC, treatment time of 6 hours, and concentration of 10% of the weight of the fabric (o.w.f.). ABTS facilitated the activity of laccase on the polyamide fabrics. Voids and cracks on the surfaces of the laccase-treated polyamide fabrics were responsible for improved wettability. The results proved that laccase treatment improved the hydrophilicity of polyamide fibers without decreasing their strength.

본 연구는 수도권과 비수도권의 다문화가정 행복감 지수에 영향을 미치는 요인 비교 분석을 하였다. 그 결과 수도권과 비수도권별로 영향을 미치는 요인이 다른 것으로 나타났다. 즉 수도권은 주관적 건강수준, 사회적 환경, 정기적 활동, 삶의 질 지수가 높을수록, 그리고 주관적 스트레스와 우울증상이 낮을수록 행복감 지수가 높아지는 것으로 나타났다. 한편 비수도권은 주관적 건강수준, 사회적 환경, 정기적 활동이 높을수록, 그리고 주관적 스트레스와 우울증상이 낮을수록 행복감 지수가 높아지는 것으로 나타났다. 본 연구를 통하여 수도권과 비수도권 다문화가정 행복지수에 영향을 미치는 요인에 차이가 있음을 알 수 있었다. 이에 다문화가정 행복감 지수를 높이기 위해서는 수도권과 비수도권에 따라 다른 방법을 강구할 필요가 있다. This study compared and analyzed factors affecting the happiness index of multi-cultural families in the metropolitan area and non-metropolitan area. As a result of analyzing the happiness index as a dependent variable, it was found that the factors affecting the metropolitan and non-metropolitan were different. As a result, in the metropolitan, the higher the subjective health level, social environment, participation in social activities, and quality of life index, the lower the subjective stress and depression, the higher the happiness index. In the non-metropolitan, the higher the subjective health level, social environment, and participation in social activities, the lower the subjective stress and depression, the higher the happiness index. It was found that there is a difference in the factors that influence the happiness index of multicultural families in the metropolitan and non-metropolitan. Therefore, in order to increase the happiness index of multicultural families, it is necessary to find a different method depending on the metropolitan and the non-metropolitan.

This study examines the effects of Evening primrose on colors, color fastness, and the antimicrobial activity of dyed fabrics. The results are as follows. The dyeing conditions of Evening primrose on cotton and mercerized cotton were optimized at 50℃, 60 minutes, and 200% (o.w.f.). In addition, Evening primrose dyeing on silk was determined at 90℃, 60 minutes and 200% (o.w.f.). The pre-mordant concentration of chemicals of cotton, mercerized cotton and silk was optimized at 1% (o.w.f.). The post-mordant concentration on mercerized cotton, silk and cotton was determined at 1% (o.w.f.) and 3% (o.w.f.), respectively. The mordant methods (such as pre-mordant and post-mordant) were slightly affected on the hue of dye-fabrics. Wet cleaning fastness of cotton was improved by post-mordant; otherwise, the wet cleaning fastness of mercerized cotton and silk was improved by a pre-mordant. The dry cleaning fastness of cotton and silk was excellent regardless of mordant methods. The dry cleaning fastness of mercerized cotton was improved by a post-mordant compared to a pre-mordant. The antimicrobial activity of Evening primrose-dyed fabrics was shown at 99.9%. The excellent antimicrobial activity of dyed fabrics remained after the mordant as well as wet and dry cleaning.

This study provides an eco-friendly dyeing processing for chitosan fiber using Oenothera odorata jacquin as a dye. The effects of chemical mordants (Al, Cu, Fe) and natural mordant (Chestnut shell) on the color change for dyed chitosan fibers were measured by K/S values, L, a*, b*, H, V, C values, color fastness, and antimicrobial activity. The results are as follows. Dyeing conditions of Oenothera odorata jacquin on chitosan fibers were optimized to 70℃, 30 minutes and 200% on weight of fabric (o.w.f.). The premordant concentration of aluminium (Al), copper (Cu) and iron (Fe) of chitosan fibers was optimized to 3% (o.w.f.) and 1% (o.w.f.), respectively. The post-mordant concentration of chemicals, such as Al, Cu and Fe, on chitosan was determined to 1% (o.w.f.). The hue of chitosan fibers by chemical mordants was measured to be reddish & yellow. The pre-mordant concentration of Chestnut shell of chitosan was optimized to 70% (o.w.f.). The post-mordant concentration of Chestnut shell on chitosan was determined to be 50% (o.w.f.). The hue of chitosan fibers by Chestnut shell mordant was measured to be reddish & yellow. The wet cleaning fastness of chitosan fibers was improved by a pre-mordant that used chemical mordants. In the case of the Chestnut shell mordant, the wet cleaning fastness was improved by a postmordant. The dry cleaning fastness of chitosan fibers was excellent regardless of mordants and mordant methods. The antimicrobial activity of the chitosan fiber was shown at 99.9% and its excellent qualities remained after the dyeing and mordant processing.

Spatial characteristics of play experience centers considering developmental characteristics and behavior characteristics of children are as follows. Integrated physical, kinematic, emotional, linguistic, cognitive and social development must be integrated and balanced. And, when comparing the frequency of play behaviors to play areas, the frequency of behaviors was relatively low, though there were a lot of play areas. With regard to the relation between development of children and space, individual spaces and integrated spaces must be properly designed and this can improve emotional stability and concentration on plays. Furthermore, this influences emotional development of children. Installing a multipurpose space in the central hall of plane for dealing with diverse play functions and programs can improve adaptation to facility and flexibility of space composition. As direct learning plays for linguistic development and indirect plays like role plays(dramatic plays), reading, listening and writing behaviors were observed. However, these behaviors are striking only in some facilities and spaces must be designed to stimulate rapidly changing development of children. Using dramatic plays(role play, housekeeping play, imaginative play and so on) is helpful in forming emotional interaction and ties by giving a chance to express language and emotions. The analysis so far is focused on behavior characteristics depending on developmental characteristics of children, based on the previous studies. But it is considered that management of proper play programs, which is based on this planning, will contribute to development of child-care support centers. Moreover, a suggestion for planning of active spaces considering behavior characteristics of children will be needed to complement this study, since there is a lack of previous studies on spatial components.

본 연구에서는 후지사과를 이용하여 천연향료를 개발하기 위한 기초자료로 활용하고자 추출방법에 따른 사과의 향기성분 특성을 비교하였다. SDE, 용매추출 및 SPME법으로 확인된 휘발성 향기성분은 각각 총 66, 32 및 54종이었으며, 주요 휘발성 향기성분으로는 (E,E)- α-farnesene, butanol, hexanol, 2-methyl butanol, hexyl hexanoate, hexyl 2-methyl butanoate, hexyl butanoate 등으로 사과의 특징적인 향기성분을 확인하였다. SDE법과 용매추출법에 의해 추출된 향기성분의 주요 화합물은 alcohol류와 hydrocarbon류로 나타났고, SPME법에 의해 추출된 향기성분의 주요화합물은 ester류와 hydrocarbon류로 상이하게 나타났다. 각 방법에 따라 추출된 휘발성 향기성분의 함량은 21.78, 7.48 및 11.67 ㎎/㎏으로 SDE법에 의해 가장 많은 향기성분이 추출되었으나 신선한 사과의 향기특성을 살리기 위해서는 SPME방법과 동일한 향기조성을 나타낼 수 있는 추출방법이 필요할 것으로 생각된다. The characteristics of volatile flavor compounds of Fuji apples were compared by different extraction methods for information leading to a natural fragrance development. The volatile flavor components of Fuji apples were extracted using simultaneous steam distillation and extraction (SDE), solvent extraction (SE), and solid-phase microextraction (SPME) methods and then analyzed by gas chromatograph-mass spectrometer. A total of 66, 32 and 54 components were identified in SDE, SE and SPME extracts, respectively. (E,E)-α-Farnesene, hexanol, butanol, 2-methyl butanol, hexyl hexanoate, hexyl 2-methyl butanoate, hexyl butanoate, and butyl hexanoate were the major flavor components in the extracts by different methods, but the composition of volatiles in the extracts were different. Alcohols and hydrocarbons were the major functional groups in SDE and SE extract whereas esters and hydrocarbons were the major functional groups in SPME extracts. SPME was the most suitable method for analysis of fresh volatiles from Fuji apples.
