This study was conducted to explore the characteristics of learner who showed free riding behavior in online collaborative learning. For this, 290 students from three universities in the metropolitan area were studied. The collected data are as follows. Learner characteristics are learning strategy, learning motivation, academic retardation behavior, and learning disposition. Interaction distinguished between frequency and type of message. Interaction levels were collected with frequency. The subjects with less than 5 interaction frequencies were defined as free-riding students. 43 students were classified as free riders. Learner characteristics were analyzed by cluster analysis. As a result, the learner characteristics were divided into five groups. All the free riding students belonged to 4 groups. The learner characteristics of 4 groups are as follows. First, the level of the learning strategy is very low. Second, learning motivation has a high tendency toward performance - oriented approach and high tendency to avoid performance. This tends to deliberately avoid learning. Third, the level of delayed behavior is high. This is deliberately putting off student activities. Fourth, learning tendency is high in academic anxiety, task value, self efficacy and learning belief are very low. This is a lack of confidence in learning.

Simple girder bridges are more economical than commonly used PSC box girder bridges in high-speed railway construction, if they secure the riding stability. In this study, the dynamic behavior and riding stability of the newly developed precast V-girder bridge are analyzed. The dynamic moving load analysis is used including two train load case : the KTX train and freight train.

All vehicles need the good quality of riding. Especially shifting shock is very important in the evaluation of the riding. Shifting shock is caused by transmission operation that one part and other part of gem are contacting together. This shock affect the feeling of driving. It is clear from these results that the shifting shock is affected by clutch pressure, pressure mode, inertia etc.

This study evaluates the economic benefit of the project constructing the international riding arena having been built at Sangju in Gyeongsangbuk-Do by the willingness to pay (WTP) of residents in the province. As the evaluation method, the dichotomous choice contingent valuation method (CVM) is adopted with the additional questions of whether his/her WTP is zero, to improve the statistical accuracy of evaluation results. Considering the arena's administrative location, the population of the surveys for analysis is confined to residents of Daegu and Gyeongsangbuk-do. The survey is conducted through personal interviews. It turns out that the WTP per household per year is evaluated as 1,847 won and the total yearly benefit of the Sangju international horse riding arena is estimated as 3.56 billion won.

A book review expands readers' choice of resources by providing them with the contents and bibliographic data of various books. It also functions as a reader support service designed to enrich their reading experiences. In particular, in the field of children's reading, literary devices are used to convey knowledge and information to children. Therefore, a review for a children's book should help children follow a book with further readings so that they can expand their literary imagination through comparative reading. In light of the above, this study looks into the case of a children's story entitled Little Red Riding Hood to identify the points that should be addressed in the "Literature Comparison" section of a book review in order to suggest further readings to readers. First, the review should provide an objective description of the content of Little Red Riding Hood. Second, it should explain the literary value of the reviewed book and the discourse that surrounds it so as to analyze its unique features that separate it from other literary works. Third, the review should provide bibliographic information on other works that use narrative structures adapted from those of Little Red Riding Hood. Fourth, it should broaden readers' choice and access by introducing, if any, works adapted from Little Red Riding Hood into other media.

Purpose: The study was to determine whether mechanical horseback-riding training according to velocity may improve trunk muscles thickness in healthy adults. Methods: Twenty healthy adults participated in this study. The subjects were divided into 2 groups as follows: 10 subjects in high velocity mechanical horseback-riding training (MHRT) and 10 subjects in low velocity MHRT. Subjects in all groups performed a total of 18 sessions 3 times a day for 20 minutes and this experiment lasted for 6 weeks. Mann-Whitney and Wilcoxon Signed Rank test were used in analysis the results of trunk muscle thickness. Ultrasonography was performed to evaluate for thickness of rectus abdominis (RA), external oblique (EO), internal oblique (IO), transverse abdominis (TrA), erector spine (ES), and multifidus (MF) in trunk muscles. Results: Results on the changes of EO, IO, and ES of high velocity MHRT showed a significant increase after 6 weeks (p<0.05). Regarding the changes of EO, IO, ES, TrA, and MF of low velocity MHRT, a significant increase was observed after 6 weeks (p<0.05). The differences in change of trunk muscle thickness before training, after 6-week training between groups, TrA and MF of low velocity MHRT were significantly higher (p<0.05). Conclusion: Based on the results of the current study, the velocity of MHRT was shown to affect change of trunk muscle thickness in healthy adults. In particular, low velocity MHRT may serve as a useful method to provide for TrA, MF thickness improvement related to trunk stabilizers.

The purpose of this study is to develop the fabric electronics-based safety protection smart athleisure fashion for night riding. Based on the characteristic analysis of products being used during night riding, the fabric LED Display and fabric type capacitive touch sensor to emphasize human friendliness were designed in detachable form through an intuitive interface to develop the smart athleisure fashion of prototype. This is meaningful in that it proposed smart Athleisure fashion products differentiated from existing products, considering the functional aspects based on fabric electronics that emphasized human friendliness and the design aspects of the customized system that can diversify design through exchange and compatibility with other Athleisure products due to detachable form. Follow-up study will focus on the improvement of textile sensor fit for the physical properties of a textile with reinforced wearability and flexibility by using Fabric Electronics and proposed customized smart fashion based on it.
