According to some previous studies, it has been suggested that affect has influence on consumers' behaviors. It has been also argued that affect has stronger influence on behavior related to tour and leisure. However, only a few studies have dealt with relationship between affect and tour considering the important correlation. This research examines on the influence of various affects on tourists' attitude and repurchase intention. This study assumes that affect takes three sub-categorized factors - pleasure, arousal and domination. It is a frequently used consumer behavior area called PAD. The purpose of this research is to examine affect and their causes experienced during tour on affectional travel agency service quality. To test the hypothesis, survey data obtained from 482 outbound tourists were used. Result shows that affect(PAD dimension) aroused by tour experiences(affectional travel agency service quality) significantly influence each attitude and repurchase intention. The implication of this finding is that marketers can gain maximum profit by providing positive affect. Because of the judgement that more future studies on unique characteristics of the affect of tour are needed, this study also describes some limitations and suggestion for the future study.

The purpose of this study was to investigate the characteristics of consumers purchasing environmentfriendly forest products, and to examine the factors affecting consumption expansion. A survey was conducted among 400 consumers over the age of 20 years. A logistic regression analysis was performed based on age, income, gender, level of education, residence area, whether or not they had children, satisfaction with product price, and product reliability. The results revealed that females were more likely to consume environment-friendly forest products than males; married people tended to buy more environment-friendly forest products than single people; and respondents with a high level of education and with children consistently showed higher willingness to purchase environmentfriendly forest products. To expand consumption of environment-friendly forest products, marketing strategies targeting well-educated, female consumers with children should be implemented.

The purpose of this study was to identify the important contents from teachers’, parents’and students’view points based on the sixth Home Economics textbook contents, to apply these results at school settings and to provide the materials as a basis for the next curriculum revision. Subjects were 59 teachers, 253 parents, and 389 students from 3 cities and 5 counties in CholaBukDo. A questionnaire which was made by the researcher was used as an instrument for this study. The results are as follows： Of 32 contents on Family life subarea, all the teachers, the parents and the students put the emphasis on sex such as pregnancy, purity, sex-ethics, etc. This result means that middle-school students emphasized the sexual identity formation and this was also a common concern about adolescents in our society. Of 37 contents of Managing home resource and Consumer life subarea, teachers though the environment pollution is an important subject and parents and students thought finding a method to conserve good environment were more important. This result reflects their concern on the environment. Of 49 contents on Dietary life, teachers and parents emphasized “the importance of nutritive elements”which is basic on their dietary life and students were more interested in “adolescence and growth and development among adolescents’nutritional characteristics and problems”which is more related to their current life. Of 40 contents on Clothing life subarea, while teachers put the emphasis on the method how they can buy ready-made clothes, parents and students wanted them to teach what kind of clothes are suitable for themselves. Of 18 contents on Residing life subarea, teachers emphasized the importance of ventilation for adjusting the room environment and students were more interested in the effective use of the residing space. By finding out what kinds of Home-economics contents are important from the view point of teachers, parents and students, this study can be a useful resource for the next curriculum revision and for selecting contents of a new-coming text book. However, restricted sampling must be considered and further studies which cover the whole area might be needed.

This study is an initial report of actual wearing conditions and attitude based on a survey of wearing outdoor wear for men and women in their 30s to 50s who enjoy daily leisure sport activities. Most middle-aged men and women who enjoy outdoor activities were interested in new trends and clothing styles. The greatest area of interest was health(42.9%), followed by leisure and sports(38.4%); in addition, hiking(40.2%) was the most popular outdoor activity. The majority of subjects participated in outdoor activities for over 5 years(34.4%). The highest frequency of outdoor activities was conducted once or twice a month, and it took one to three hours for each activity. Nearly half of the respondents( 47.7%) answered that the goal of outdoor activities was to maintain their health. Subjects in their 40s and 50s were more equipped in their outdoor activities and in their 50s made ongoing investments despite costs. When wearing clothing, the subjects placed a priority on design(in the case of subjects in their 30s) and comfort(for subjects in their 40s and 50s). This survey shows that the subjects emphasized access to outdoor wear and equipment. In all age groups, the biggest complaint about outdoor wear was price; in addition, they were unsatisfied with the length and the sleeves of outdoor jackets. Outdoor wear will draw a positive attention for its practical use of clothing if it is developed according to consumer demands based on functionality for outdoor activities and convenience in daily life.

Aspheric pick-up lenses are increasingly used in consumer products such as computer and multimedia, as their mass production has become possible owing to the injection molding process. However still much work needs to be done for more effective manufacture of aspheric lenses, one area of which is the in-line inspection of produced lenses. In this paper, we present a lateral-shearing interferometer that has specially been designed to have a high immunity to external vibration and atmospheric disturbance. The interferometer comprises four prisms. They are directly attached to each other using an immersion oil so that relative sliding motions between the prisms are allowed. Their relative displacement can readily generate necessary lateral-shearing and phase-shifting to determine the wavefront of the beam collimated by the lens under inspection. A special phase-measuring algorithm of arbitrary-bucket is adopted to compensate the phase-shifting error caused by the thickness reduction in the immersion oil. Zernike polynomial fitting has done for determinating quantitative aberration of aspheric pick-up lenses. The interferometer built in this work is robust to external mechanical vibration and atmospheric disturbance so that experimental results show that it has a repeatability of less than λ/100.

In this paper, we proposed a non-contact respiration measurement system with ultrasonic proximity sensor. Ultrasonic proximity sensor approach of respiration measurement which respiration signatures and rates can be derived in real-time for long-term monitoring is presented. 240 kHz ultrasonic sensor has been applied for the proposed measurement system. The time of flight of sound wave between the transmitted signal and received signal have been used for a respiration measurement from abdominal area. Respiration rates measured with the ultrasonic proximity sensor were compared with those measured with standard techniques on 5 human subjects. Accurate measurement of respiration rate is shown from the 50 cm measurement distance. The data from the method comparison study is used to confirm the performance of the proposed measurement system. The current version of respiratory rate detection system using ultrasonic can successfully measure respiration rate. The proposed measurement method could be used for monitoring unconscious persons from a relatively close range, avoiding the need to apply electrodes or other sensors in the correct position and to wire the subject to the monitor. Monitoring respiration using ultrasonic sensor offers a promising possibility of non-contact measurement of respiration rates. Especially, this technology offers a potentially inexpensive implementation that could extend applications to consumer home-healthcare and mobile-healthcare products. Further advances in the sensor design, system design and signal processing can increase the range of the measurement and quality of the rate-finding for broadening the potential application areas of this technology.
