As the used trading market grows centered on online platforms, it is evolving from practical consumption to pursuing various forms of consumption value. Consumers purchase rare products, enjoy the transaction itself with consumers with the same preference, and investment or eco-friendly value consumption is also increasing. In this regard, the transaction of the second-hand transaction app service must have sincerity in order to respond to various consumption values. In addition, it is necessary to study what components the second-hand trading app service should aim for to secure authenticity and how the usefulness and ease of second-hand trading apps affect the relationship. The research used a questionnaire method to test hypotheses and surveyed 215 consumers in their 20s, 30s, and 40s who had purchased used clothing online within a year. Among them, 200 responses, excluding outliers, were statistically analyzed using SPSS 21.0 and AMOS 22.0 as confirmatory factor analysis and structural equation models. This study aims to determine the effect of the authenticity of the online used trading app service on the satisfaction of the used trading app service. To this end, based on the previous research results, the following research hypotheses were established and verified statistically. First, the authenticity of the online used trading app service will significantly impact the satisfaction of the used trading app service. Second, the usefulness of the used trading app service will have a moderating effect on the effect of the authenticity of the used trading app service on the satisfaction of the used trading app service. Third, the ease of the used trading app service will have a moderating effect on the authenticity of the used trading app service on the satisfaction of the used trading app service. As a result of the study, the authenticity of the used trading app service significantly affected the satisfaction of the used trading app service. Appeared to be The results of this study will help understand used transaction app services where consumption of used products occurs from the viewpoint of product circular use behavior and can be used as a strategic plan to promote the use of used transaction apps in the future.

Purpose: A hand-washing program using role-playing was developed for preschool children and tested to verify its usefulness. Methods: The participants were 46 preschool children (experimental group, 23; control group, 23). Data were collected from August 7, 2017 to September 20, 2017. The first posttest was carried out on the day after the initial intervention was completed, and the second posttest was performed after a month. Data were analyzed using the $x^2$ test, Fisher exact test, Shapiro-Wilk test, Mann-Whitney test, and Friedman test. Results: In the experimental group, the frequency of practicing hand-washing was significantly higher than in the control group on the next day (z=-4.94, p<.001) and after a month (z=-3.15, p=.002). The accuracy of hand-washing was significantly higher in the experimental group than in the control group on the next day (z=-4.02, p<.001) and after a month (z=-3.86, p<.001). Conclusion: The hand-washing program developed in this study was found to be an effective intervention strategy for improving the frequency and accuracy of hand-washing among preschool children.

The purpose of this study is to clearly understand the Korean consumer's socially responsible consumption attitude and disposition behavior through revealing by use Fishbein's Multi-Attributes Model as a conceptual frame, the relationship between the socially responsible clothing consumption attitude factors and disposition behavior pattern, and relations of demographic variables. Data were collected from the adult females residing in Seoul. Judgment Sampling were. performed twice during March of 1996 and total 549 sets of answers were used for final analysis. The result are following. First, by looking at the relationship between intrinsic side of socially responsible consumption attitude and disposition behavior, the attitude shows more economical disposition when consumers are in considerate about preservation of natural resources and clothing consumption and when consumers favor purchasing a second hand product, On the other hand, consumers' behavior shows more altruistic disposition, when they favor recycling and acquisition of second hand clothing and when not favor fashion. The result of analysis of relationship between the socially responsible clothing consumption attitude and demographic variables shows that income, age and education level relates to some intrinsic side of socially responsible clothing consumption attitude. On the other side, the analysis result shows that consumers with relatively lower education normally practice economical dispotion, while consumers with higher education level do altruistic disposition. Also, elder and married consumers tend to do more altruistic disposition.

In this paper, we propose the classification and tracking method of the hand region using deformable template and condensation. To do this, first, we extract the hand region by using the fuzzy color filter and HCbCr color model. Second, we extract the edge of hand by applying the Canny edge algorithm. Third, we find the first template by calculating the conditional probability between the extracted edge and the model edge. If the accurate template of the first object is decided, the condensation algorithm tries to track it. Finally, we demonstrate the effectiveness and feasibility of the proposed method through some experiments.

In this paper, we propose a new hand gesture recognition scheme using hand poses captured from a web camera. The key idea of this scheme is to extract skin color from the background-subtracted image. To extract skin color, in the first phase, we subtract background by repeatedly comparing the stored initial frame with next frames. And then we eliminate noise using dynamic table. In the second phase, we exactly recognize hand gesture by extracting skin color from ${YC_b}{C_r}$ color region.

The drinking manners of the modern generaton were reviewed based on historical records. First, for reasons of health, we should reject the drinking from the same cup as others in reciprocation. Second, if the other people are older or younger brothers above the same level, pouring with one hand is all right, but if 5 years older or more, or stranger, grasp the bottle in two hands in the following manner. With the right hand under the bottle, and the left hand supporting its side, carefully pour wine not to show the palm of the hand. Third, ladies, also, can drink freely at the same table, but if people of the opposite sex are sitting together, they should pour with two hands to convey the meaning of courteous treatment. Fourth, because the level of our living is not two high, we must not order more them we can use, so that when we are finished, there will be no remainder.

The objectives of this study were: (a) to find the maximum ac- ceptable weight which can be carried for 8 hours using a psycho- physical method for front, side (one hand and two hands) and back carrying, and (b) to develop models which could predict the ac- ceptable maximum weight in carrying using isometric strength and anthropometric data. A series of laboratory experiments were conducted to find the maximum acceptable weight in front side and back carrying. Six college students participated in the experiment. It was found that subjects were willing to carry the heaviest load using two-hand side carrying (average maximum acceptable weight: 7.76 kg). Back carrying was the close second with 6.62 kg. Also, there was a significant difference (p< 0.01) in maximum acceptable weight for carrying between one-hand (4.40kg) and two-hand side carrying.
