Purpose: The purpose of this study was to conduct an analysis of kinematics of lower extremities and trunk in stance phase of walking according to turning direction. Methods: Ten university students (five male, five female) who were in their 20s (mean age was 20.6 years old) participated in this study. Participants did not have participants did not have any problem with skeletal muscular system. We used the "Qualisys motion capture system" for analysis of trunk and lower extremity movement in stance phase of walking according to turning direction. We collected data while subjects walked a distance of 10 m, and at the 6 m line, subjects were required to turn to the left side and the right leg was positioned in stance phase and the left leg was positioned in swing. For data analysis, the SPSS for Windows ver. 20.0 statistics program was used in performance of one way analysis of variance according to turning direction. Results: Significant difference of trunk and lower extremities was observed for turning direction according to walking cycle (p<0.05). Upper trunk movement showed a greater increase at three dimensions than lower trunk, and in heel off phase, pelvic movement showed a greater increase than lower trunk (p<0.05). In 45 degree and 90 degrees of turning direction, all movements of trunk and lower extremities were significantly different among three events of stance phase (p<0.05). Conclusion: We suggest that three-dimensional movement analysis of trunk and lower extremities during turning movement was very important in order to indicate increasing balance or walking ability for people with impaired movement or walking.

This study was to provide the information for optimum utilization of the air-conditioning system in the human health and energy saving perspective. Subjects were 17 male and female college students(7 males and 10 females) with normal weight. They wore a short sleeved shirt, knee length trousers, socks, and underwear(0.4clo). They were asked to choose the preferred temperature from different environmental temperatures($28^{\circ}C$, $25^{\circ}C$). The physiological responses were measured and the subjective sensation was voted during the step changes of environmental temperature, starting at $28^{\circ}C$ to $25^{\circ}C$ with $1^{\circ}C$ decrease every 20 minutes. The preferred temperature was $25.9{\pm}0.4^{\circ}C$ for males and $26.9{\pm}0.2^{\circ}C$ for females at $28^{\circ}C$ and $24.8{\pm}0.6^{\circ}C$ for males and $25.6{\pm}0.1^{\circ}C$ for females at $25^{\circ}C$. The preferred temperature decreased about $1.3^{\circ}C$ while the environmental temperature changed $3^{\circ}C$. During the environmental step changes, mean skin temperature decreased more in females while the oxygen uptake and rectal temperature were kept constant for both males and females. We found the preferred temperature was affected by the exposed temperature and the thermal sensation in the condition. Subjects preferred a lower environmental temperature when they were exposed to a lower temperature with cooler sensation. Therefore, in the perspective of human health and energy saving, it is recommended to start setting the air-conditioning temperature higher than the preferred temperature.

Although consumer ethical behavior related with illegal copies of digital software has been considered to be an important issue, not many studies have attempted to examine the issue. Firstly, this study attemped to explain the moral judgment and intention to make illegal copies of smart phone applications for college students. Secondly, psychological factors such as moral intensity and perceived risk related to making illegal copies were tested to be significantly different in individual characteristics such as experience of ethical education and past experience of making illegal copies of software, sex, age and household income. Thirdly, the effect of related factors such as psychological factors and individual characteristics was estimated to significantly influence moral judgment and intention to make illegal copies. Two step method(using LIMDEP program) was applied to estimate the model as a structural equation model. According to the results of this study, magnitude of consequences, financial risk and performance risk were found to be significantly different in income groups(less than middle class vs more than middle class). Prosecution risk was found to be significantly different in gender groups(female vs male). In addition, social consensus, financial risk, performance risk and prosecution risk were found to be significantly different in ethical education groups(experience vs no experience). Furthermore, moral judgment for making illegal copies of smart phone applications was found to be significantly influenced by income, ethical education, magnitude of consequences, temporal immediacy and social consensus. And intention to make illegal copies of smart phone applications was found to be significantly influenced by moral judgment, age, financial risk, performance risk and prosecution risk.

The purpose of this thesis is in investigating the Korean twenties face color, according to the seasons, thus presenting a sample Korean Facial Color Map. The face is divided into 20 parts to take measures, and investigated through the four seasons. Minolta Chrome Meter CR-200 has been used for taking measures of the face color. Measuring subjects and area are, University students of both sex, living in the Suncheon. They are of ages the twenties. Classified measuring values of the skin colors are expressed following to the A. H. Munsell's color system. The result of this study is as followed. When comparing parts among male and female(make-up and no make-up) groups for changes with seasonal hue and value of a face color, differences have been sighted among these three groups following the seasons ; Spring(March), Summer(June), Autumn (September) and Winter(December). According to the result of Duncan's proof, the differences of the women group with the make-up attitude was shown only in value from Summer and Autumn, but no differences have been sighted between the make-up group and the no make-up group, concerning hue. Concerning hue, it was shown that men had a redder hue than women in all seasons. In Spring, both men and women had the strongest red hue, then from Summer to Autumn a strong yellowish hue appeared, to make place to a diverse coloring in Winter, followed by a reddish hue, to start all over again. Value number proved to be lower in the Summer and Autumn for the no make-up group when compared to the make-up group, showing an averaging high number for all seasons when putting on make-up; and men value number shows the lowest of the three groups.

Purpose: The purpose of this study is to find out whether the color change of the LED light source has a significant effect on the beta wave activity of EEG in the learning state. Methods: The subjects of the experiment were 20 male and female college students between the ages of 19 and 25 who routinely perform their studies. In the created learning environment, the EEG change according to the change in the lighting color was measured while solving the Mensa thinking ability problem while sitting on a desk with LED lights installed on the top and a chair with a footrest to stabilize the legs. The light source consisted of 3 ready-made colors and 6 newly created colors. A total of 9 color light stimuli were given for 2 minutes each, and the EEG change of the subject was observed. After the experiment, the correlation was analyzed based on the mid-beta wave data recorded on the QEEG according to the color change of light and the Mensa problem score. Results: It was found that the activation of mid-beta waves was stimulated in the temporal lobes (T5, T3, T6, T4) and occipital lobes (O1, O2) of all subjects who focused on solving Mensa thinking problems. As a result of comparing the top 20% and the bottom 20% of problem solving scores, the upper group had no effect of lighting, while the lower group showed increased beta wave activity in response to color light stimulation in the order of T4, T6, and T5. Implications: It was confirmed that the color of light that activates the middle beta wave varies greatly depending on the subject's attention and learning ability, and it is judged that the color of light including the green wavelength is helpful in activating the middle beta wave in the group with low learning ability.

This study was conducted to investigate the response of the human body to stress induced by wall recording of subway stations in the city center. The experiment was conducted as a simulation exercise, and six images were selected and produced based on Subway Line 2, a representative underground space in Seoul. The study participants included 24 male and female college students. A three-minute experiment was conducted, during which the participants were shown the control image and green wall image once each. To measure psychological status, the following measurement indicators were used: Semantic Differential, Positive Affect and Negative Affect Schedule and State-Trait Anxiety Inventory. Physiological changes were investigated by tracking participants' heart rate and blood pressure. Results showed that parasympathetic and sympathetic nerves were activated in the presence of the green wall in the subway station. The psychological evaluation analysis revealed that negative affect toward underground space decreased, while positive affect increased. This study found that the green wall in subway stations has a stable effect on the human body, both psychologically and physiologically. In the future, green walls in underground spaces can be used to reduce psychological stress and increase physiological relaxation.

The purpose of this study is to understand consumer awareness and preference regarding rice cakes by surveying the awareness, preference, and consumption behavior of college students regarding rice cakes, and to survey their perception and usage of rice cakes, thereby using the results as basic data to establish measures to develop Korea's rice cakes. To sum up the study's results, the survey included both male (54.5%) and female (45.5%) subjects. Those aged "20 to 23" accounted for the largest share (67.9%) of total respondents, and those majoring in "humanities and social studies" comprised the largest portion (47.8%). A majority of the respondents resided in "small and medium-sized cities", and most either lived at home or lived away from their families. A majority of the subjects received monthly allowances ranging from 200,000 to 300,000 won. In order of awareness, the most well-known type of rice cake was "injeolmi (rice cake made from glutinous rice and coated with bean flour)", followed by "songpyeon (half-moon-shaped rice cake)", "garaeddeok (bar rice cake)", and "baekseolgi (steamed white rice cake)". The women were better aware of "injeolmi", "baekseolgi", and "garaeddeok" than the men, and "soemeoriddeok" was not commonly known among either gender. In terms of preferences for rice cakes, overall, the subjects liked "injeolmi" and "songpyeon" the most. However, certain differences were found in preferences for rice cakes between the men and women. The women exhibited higher levels of preference for "injeolmi" and "songpyeon" than the men. On the other hand, the men revealed higher levels of preference for "baekseolgi", "jeolpyeon", and "garaeddeok" than the women. The most common answer to important factors for popularizing rice cakes was "a diverse assortment of rice cakes", followed by "the development of creative technologies" and "the taste of rice cakes reflecting consumer needs", in order of importance. Among the important factors to popularize rice cakes, "the development of unique packaging containers for rice cakes" (p<0.05) and "the development of proper packaging materials" (p<0.05) showed statistically significant differences. In the survey of consumption of rice cakes, the most frequent answer to the question "why do you like rice cakes? was "their tastes are good" with 146 respondents, followed by "I have been eating them for long" with 115 respondents. To the question "when do you use rice cakes", the most frequent answer was "I use them in daily life" with 133 respondents, followed by "I use them at special events" with 115 respondents. The women were found to use rice cakes frequently in daily life, whereas the men used them frequently at special events. When asked whether they had the intention to use rice cakes as a meal substitute, 100 men answered that they had no intention, whereas 96 women answered that they had the intention. When asked about the type of rice cake considered suitable for a meal substitute, the most popular answer was "injeolmi" with 108 respondents, followed by "baekseolgi" with 106 respondents.

Internet shopping provides convenience to consumers, however, in recent years the consumer's return rate and return-related disputes continue to increase. This article examines the characteristics of return behavior through return experiences of internet clothing purchases. For an empirical study, questionnaires were handed out to 317 undergraduate male and female students, in which the results had been used for data analysis. Data were analyzed through SPSS 12.0 software, descriptive statistics, factor analysis, t-test, ANDVA analysis, Duncan test, and $x^2-test$. The results are the following: The analysis of consumers' return factor for clothes in Internet shopping showed there are five factors: product and quality, delivery, impulse buying, change of mind, and service. There is a significant difference in product quality of return factors depending on the availability of the return experience. Thus, consumers with return experience showed more return tendency owing to product quality factor than consumers without return experience. The availability of consumer's return experience was significantly related to information search. Consumers with return experience showed more consistent information search than consumers without return experience. There were significant differences in perceived risks depending on the availability and degree of consumer's return experience. In other words, consumers with return experience perceived more account related risk than consumers without return experience. Moreover, the more return experience the consumer has, the more risks consumers perceived in product performance.
