노래를 부르는 가수에게 있어 가장 중요한 부분은 정확한 음정과 박자이다. 그와 더불어 중요한 부분이 바로 발음인데, 노래라고 하는 것이 멜로디와 가사말로 구성되어 있기 때문에 발음이 불명확하면 내용이 전달되지 않기 때문이다. 성악이나 판소리의 경우 사전에 충분한 훈련을 통해 음정, 박자와 더불어 발음부분까지 충분히 숙지하는 경우가 대부분이지만 대중음악부분은 모든 가수들이 충분한 훈련 기간을 거쳐 데뷔하는 경우가 많지 않기 때문에 상당부분 미숙한 것이 사실이다. 그중에 가장 소홀히하는 부분이 발음인데, 노래에 멋을 부린다고 하기엔 발음이 너무 과하거나 왜곡되게 표현되는 부분이 많다. 본 연구에서는 노래를 부를 때의 정확한 발음법과 노래의 느낌을 살릴 수 있는 효과적인 발음법에 관해 연구해 본다.

'gender' means sex in a social sense and 'sex'is more close to the concept of that discussed in biological light. 'Gender is more adequate word in expressing gender equality of both sexes than 'sex'that gives us discriminating impression and implies tout we should actualize equality between both sexes in all field of social activities. Though more and more women have been advanced into the job that was once regarded as a men only-area and the concrete list of iou for men and women has been changed in the process of job structure transition, women stiff take full charge of all kind of houseworks so they're still under the double torture of housework and their job. Most of the job in which men used to engaged in the past is now mechanized. and we can't deny that modern technology triggered women's participation in public affairs by helping them to lead comfortable family life without any assistant or trustee for housework. Under these trend of our times, we made an attempt to look into design mainly from the standpoint of women by raising the issue of correlation between women's labor in society and houseworks in the hope that current design and changes into one that can rejects women's position and allows them independent choice in the field involved with our real life.

This study aimed to develop a group rap making program and examine its applicability to improve communication skills of adolescents with mild intellectual disabilities (ID). Three adolescents with ID participated in a total of six 50-minute group sessions over 4 weeks. The group rap making program included three stages: understanding the context of communication, learning how to communicate with others, and applying the communicative behaviors in a group setting. To examine changes in the participants' communication skills, the rap lyrics constructed by participants were analyzed and communicative behaviors were observed during sessions and analyzed in terms of asking questions and providing information to others. Also, a social communication skills checklist was rated by the participant's caregivers. The analysis of rap lyrics showed that the expressions included in the rap were diversified as the session proceeded. Changes in observed behaviors supported that participants became to engage in communication with others more actively in order to complete the group rap. While the social communication skills checklist tended to increase, there was a difference in degree of change depending on the level of language communication skills. These results indicate that a group rap making can be an effective option for these adolescents to learn how to communicate with their peers, which presents implications for how rap making can be used for therapeutic purpose with more diversified population.

The purpose of this study was to investigate the differences in family cohesion and family adaptability between college students and their parents to identify the factors that affect family cohesion and family adaptability using a descriptive research study design. The subjects of this study were 197 college students and their parents. The data were analyzed using descriptive statistics, the t-test, ANOVA, correlation and multiple regression analysis by SPSS for Windows (ver. 22.0). The mean of the family function index of the subjects was $7.42{\pm}2.28$ on the scale of 1 to 10, and that of the normal family functional group was 65.48%. There was no significant difference in family cohesion between the college students and their parents, and family adaptability was significantly different in discipline(t=-3.100, p<.01) and role(t=.212, p<.05). The factors affecting the family adaptability of the students were the sharing of family activities, emotional intimacy and attending family events, which showed a combined explanatory power of 45.9%. The factors affecting the family cohesion of the parents were housework assignment, emotional intimacy and attending family events, which showed a combined explanatory power of 51.4%. Family emotional intimacy and attending family events, as well as the sharing of family activities, were found to be important to the family adaptability of the college students and housework assignment was found to be important to the family cohesion of the parents.

To prepare acrylic resin coatings containing 70% of solids, we used n-butyl methacrylate(BMA), methyl methacrylate(MMA), 2-hydroxyethyl methacrylate(2-HEMA), and acetoacetoxyethyl acrylate(AAEA), caprolactone acrylate(CLA) as raw materials, the glass transition temperature(T_g) of acrylic copolymer was adjusted around 50 ℃. The viscosity and molecular weight of the acrylic resins was increased with increasing OH values. Di-tert-amyl peroxide was found to be the suitable initiator to get high-solids acrylic resins. The optimum reaction conditions found in the study are 5 wt% of initiator, 4 wt% of chain transfer agent, 4 hrs of dropping time, and 140 ℃ of reaction temperature. The structure of the synthesized resins were characterized by FT-IR and ¹H-NMR spectroscopy. Number average molecular weight of 1900~2600 and molecular wight distribution of 1.4~2.1 were obtained. Crosslinked acrylic urethane clear coatings were obtained by curing reaction between the synthesized acrylic resins and hexamethylene diisocyanate trimer(Desmodur N-3300), the equivalent ratio of NCO/OH was 1.2/1.0. The physical properties from the following studies were carried out: viscosity(Zahn cup #2), adhesion, drying time, pot-life, pensil hardness, and 60° specular gloss. Various properties of the acrylic urethane clear coatings were also evaluated on the coating specimens. Adhesion property to a substrate, drying time, pot-life, pencil hardness, and 60° specular gloss of prepared paint showed quite good properties. Futhermore, prepared paint containing 10% of CLA showed quite good properties for adhesion, low viscosity and high hardness.

This study has been historically reviewed the clothing and textiles education through references. The clothing and textiles education had been informally offered as a part of household skill, skill of daily life and home skill before the law of school education was established. Therefore, we have reviewed the changes in the clothing and textiles education by separating the prior period between the end of the old Korea and the liberation in 1945, from the later period from the liberation up to now. And also contents of clothing and textiles education between before and after the revision of the 7th curriculum were compared and analyzed. The clothing and textiles education had put emphasis on sewing, handicraft and household during the prior period from the end of the old Korea to the liberation, but after liberation, it became involved in Home Economics Education. The number of classes and the contents of clothing and textiles education had been increased and deepened from the 1st term to the 5th term of curriculum. In particular, the 4th and 5th term of curriculum became a turning point where home life section was intensified. Even though the number of classes was reduced during the 6th term of curriculum, with increase in target school grades for this education, and Home Economics in the middle school remained an independent subject matter. However, during the 7th term of curriculum, Technology-Home Economics Education in the middle school courses led to losing independent subject name and shrinking its contents. Through the revision in the 7th curriculum, the clothing and textiles education achieved great improvement and progress by gaining balance in distribution of contents among school grades and balance between theory and practice. However it still remains as an issue to be more studied and resolved how well the contents are matched with the interests and attention of students. We need to consider and reflect request of students under learner-centered curriculum. Considering enormous changes in the environment surrounding the clothing and textiles education, it is crystal clear that the gap between existing contents of education and teaching methods and our real life will be widened. Because students' perceptions of value have been diversified, it is our task to develop better contents and learning system in order to help students have interests, attention and desire in clothing and textiles life in line with social needs for desirable clothing and textiles education.
