  • Purpose : The purpose of this study is to investigate how the existence of companion animals and the type of companion animals affect the quality of life and emotional stability of adults in their 20s. Methods : The subjects of this study were adults in their twenties living in Busan who could understand the method of this study. The survey method was conducted with a questionnaire, consisting of 4 questions on general characteristics, 26 questions on quality of life, and 20 questions on emotional stability for a total of 50 questions. An independent t-test and one-way ANOVA were used to verify the difference in quality of life and emotional stability according to general characteristics. Results : As a result of analyzing the difference in the quality of life of the study subjects, the case of having a companion animal scored statistically significantly higher in the satisfaction of the physical domain, psychological domain, living environment domain, overall quality of life domain, and social domain. In addition, there was a statistically significant difference in the case of companion animals according to the type of companion animal. However, there was no statistical significance in the analysis of differences in emotional stability of study subjects according to the presence or absence of companion animals. Conclusion : This study was conducted with 400 adults in their twenties to determine the effects of the presence and absence and type of companion animals on the quality of life and emotional stability of adults in their twenties. As a result, the group with companion animals showed higher satisfaction scores than the group without companion animals in terms of quality of life. This suggests that raising companion animals for adults in their 20s has a positive effect on improving their quality of life. Therefore, it can be recommended for the physical, psychological, and social health of adults in their 20s.

  • The purposes this study were to a) analyze the revisiting ratio of resting customers after issuing online coupons, b) compare the characteristics of coupon redemption customers with non-redemption customers. For this study, the customers of M restaurant who did not revisit during the last 8 months were classified as 'resting customers', totaling 4,052 customers. The online coupons, valid for 9 months, were sent via e-mail to those customers. After that, the data collected from those who redeemed the coupon in September 2006 was utilized. As a result of sending the coupon to 4,052 resting customers, 1,288 customers redeemed the coupon during the study period, showing relatively high redemption ratio (31.6%). The average check of customers with the online coupon was decreased by 22% compared with customers without the coupon, but the party size remained almost the same, 2.6 customers, and also the redemption ratio was increasing as the expiration date of the coupon was approaching. The redemption ratio of female (35.3%) was much higher than male (19.2%), representing higher redemption possibility of the female customers by issuing the coupon. The redemption ratio of the twenties (69.1%) was obviously higher than other age groups. Also, the non-redemption ratio of other groups except the twenties was higher than the redemption ratio. The redemption ratio of low-educated was higher, under college degree (58.6%), college degree (35.4%), and over college degree (16.6%). Following the result of the average visiting frequency of redemption customers during last the 8 months was 4.2, the frequency of non-redemption customers was 9.8. The total average visiting of non-redemption customer was 10.5, and that of redemption customers was 8.6. Customers who visited the restaurant less frequently in the past have higher possibility to revisit after receiving the coupon.

  • Recently, Basic patterns with excellent body fitness and automation availability are required to be developed in order to automate the patterns of women's clothes. In this study, this reference points, reference lines and segments were fixed onto 3D scan data for the lower body the women in their twenties, they were directly spread out to be 2D flat pattern to facilitate development into the design of slacks adhered closely to the human body such as special and highly-functional clothes, and then slacks 2D pattern was developed for the purpose of seeking scientific approach to the development into basic form slacks and 3d emotional pattern. For conversion of 3D pattern into 2D flat pattern, reference points and segments were created by using Rapid Form of 3D shape analysis software, and triangle mesh of the body surface of the created shape was developed with Auto CAD 2005. The correspondence between slacks and human body was examined by the fixation of major reference lines. Specially, the wearing characteristics of slacks were considered by the fixation of side lines in consideration of posture. As a result of using the way of development to constantly maintain the length while 3D triangle mesh is converted into 2D flat mesh, the shape was shown to be excellently reproduced, and the area of flat pattern was increased compared to the shape of parting plane. Also, the sunk-in curve like the brief line of front crotch length needed a cutting line when it was closely adhered, when mesh was overlapped, and the pattern area was smaller compared to the actual shape.
