The number of the disabled person had been increased for the industrial accident and the environmental pollution. Especially, developmental disability has the high prevalence rate between 5% and 10% of the whole children. The children with a developmental disability can be treated by the physical therapy, the occupational therapy, the psychology therapy, speech therapy, and art therapy. Visual preception which is function to recognize the external environment through the optic organ could be related to most behaviors on the everyday life. But because the children with disability could not develop the visual-preception enough, they came to have difficulties in executing daily life project. For this reason, it is most important to understand the estimation and the cure on the visual-preception in the pediatric occupational therapy. To improve the visual-preception power, we have many kind of methods including sensory integration, training program for the visual-perception and art-craft program. Particularly, the art-craft which is the representative activity for making something by hands, can be applied to anyone. As the study on the brain has been activated, it was proved that handicraft actives could have an good effect on the brain function and using brain. When the fine motor exercise and more delicate and accurate motion were carried, these motions need the essential help of the visual-perception. So it could be expected that using the repetitive hand function by art-craft makes the brain function improve, when a activity that needs a fine motor exercise and more delicate, accurate motion was carried, It also indicates that the art-craft program has a clear treatment value. Though the intervention between visual-perception development and visual-perception disability have a majority in the field of occupational therapy, there is a few study yet. Therefore, this study tried to look back on the necessity of applying the art-craft program to the children with disability as the prestudy for preliminary validity of the master's thesis.

This paper proposes a tourism recommendation system in intelligent cloud environment using information of tourist behavior applied with perceived value. This proposed system applied tourist information and empirical analysis information that reflected the perceptual value of tourists in their behavior to the tourism recommendation system using wide and deep learning technology. This proposal system was applied to the tourism recommendation system by collecting and analyzing various tourist information that can be collected and analyzing the values that tourists were usually aware of and the intentions of people's behavior. It provides empirical information by analyzing and mapping the association of tourism information, perceived value and behavior to tourism platforms in various fields that have been used. In addition, the tourism recommendation system using wide and deep learning technology, which can achieve both memorization and generalization in one model by learning linear model components and neural only components together, and the method of pipeline operation was presented. As a result of applying wide and deep learning model, the recommendation system presented in this paper showed that the app subscription rate on the visiting page of the tourism-related app store increased by 3.9% compared to the control group, and the other 1% group applied a model using only the same variables and only the deep side of the neural network structure, resulting in a 1% increase in subscription rate compared to the model using only the deep side. In addition, by measuring the area (AUC) below the receiver operating characteristic curve for the dataset, offline AUC was also derived that the wide-and-deep learning model was somewhat higher, but more influential in online traffic.

To analyze the crustal velocity structures beneath 21 broadband seismic stations in Gangwon Province, South Korea, we first applied the H-κ stacking method to 139 teleseismic event data (Mw ≥ 5.8 and the epicentral distance of 30° - 90°) occurring between March 18, 2019 and December 31, 2022 to estimate the Moho depths and V_p/V_s ratios beneath each station. The Moho depths and V_p/V_s ratios from the H-κ stacking method range from 24.9 to 33.2 km depth and 1.695 - 1.760, respectively, and the estimated V_p/V_s ratios were applied to the joint inversion of receiver functions and surface wave dispersion to obtain 1-D crustal velocity models beneath each station. The resulting Moho depths range from 25.9 to 33.7 km depth, similar to the results from the H-κ stacking method. Moho depth results from the both methods are generally consistent with Airy's isostasy. The 1-D crustal velocity models confirm that the existence of 2 km thick low-velocity layers with P-wave velocities of 5 km/s or less at some stations in the Taebaeksan basin, and at the stations CHNB and GAPB in northern Gangwon Province, which are located above the Cenozoic sedimentary layer. The station SH2B, although not overlying a sedimentary layer, has a low P-wave velocity near the surface, which is probably due to various factors such as weathering of the bedrock. We also observe a velocity inversion with decreasing velocity with depth at all stations within 4 - 12 km depths, and mid-crustal discontinuities possibly due to density differences in the rocks at around 10 km depth below some stations.

This study was designed to find answers for the two questions that had been raised in the study of Lee and Fortner(2000): 1) How can the appropriateness of classification of environmental issues by perceived certainty and 2) How are perceived certainty, tangibility, significance of environmental issues and willingness to act to solve those problems related to each other\ulcorner A questionnaire consisted of 40 questions was administered to 144 college students. Results of the study revealed that classification through cluster analysis appeared to be more appropriate and credible than classification by mean scores or medians. Four major factors were found to have high positive correlations to each other as hypothesized. These results imply for environmental educations that people's attitude toward and behavior on environmental problems are likely to be more strongly and meaningfully associated with their perceptions of those problems that are subjective and flexible than physical or chemical characteristics of the problems that are frequently considered as objective.

The purpose of this study is to examine the effect of company characteristics and individual characteristics perceived by employees of small businesses on job satisfaction and especially to seek activation of the organization by extending from previous studies to examine the intermediary role of company innovation and applying management measures focusing on the environment of changing global society where CEOs of small businesses cause job satisfaction of organizational members and present the direction for the improvement of management and institutional development. This study was carried out for about 2 months targeting employees of small businesses and the results of empirical analysis are as follows: First, company characteristics and individual characteristics perceived by employees of small businesses turned out to have a positive (+)effect on job satisfaction but the hypothesis that job stress affects job satisfaction was not significant. Second, of the effects of company characteristics and individual characteristics perceived by employees of small businesses on company innovation, organization flexibility and CEO's leadership, company communication and degree of cooperation between departments, individuals, challenge of individuals perceived individual characteristics were found to affect company innovation but the hypothesis that job stress affects it was not significant. Third, company innovation was found to have a positive (+)effect on job satisfaction and fourth, in the intermediary effect verification of company innovation between company characteristics and individual characteristics perceived by employees and job satisfaction, organization flexibility and communication, collaboration turned out to perform partial intermediation and CEO's leadership to perform full intermediation and individual challenge performance to perform full intermediation and the intermediary effect of job stress was not proven. These results are company characteristics and individual characteristics that is the perception of the independent variables in SME employees is not only a direct relationship with job satisfaction, suggesting that also has an indirect effect is mediated depending on the innovation of the company. Therefore, it can be seen that even for the innovation performance of enterprises is important to increase the job satisfaction of employees of SMEs. In particular, the conductivity of the leadership and individual parameters so completely over the innovativeness of the company is the result of job satisfaction itgetda can be said that the innovation efforts of the organization is effective at the same time be pursued.

The dissemination of smart devices has made a lot of changes in overall social activities. In particular, people use various types of smart devices in their spare time, such as watching video clips, but there is a lack of research on external factors influencing the attitude toward using such devices. Therefore, in this study, the effects of video viewing environmental factors (e.g. screen size and video length) and personal factors (e.g. gender and need for entertainment) on perceived ease of use, perceived usefulness, and attitude to use devices based on technology acceptance model. As a result of analyzing 660 users having different smart devices, the attitude to use smart devices is more positive as the screen size increases, but there is no difference according to gender. In addition, while the length of video clips does not affect the attitude to use, the need for entertainment positively affects the attitude to use. Based on the results of this study, we expect that it can be used for optimized customer marketing and management strategy that integrates product development and video content production in consideration of factors such as video viewing environmental factors and personal factors.

The present study examined the effects of the factors of port service quality on customer satisfaction and surveyed customers' perception on service quality and their satisfaction with port services by comparing Incheon Port with Qingdo Port, Tianjin Port and Dalian Port. According to the results, the quality of port services can be divided into three levels-inner quality, external environment quality and interaction quality, and except the external environment quality of the Dalian Port, the three levels of service quality were found to have significant effects on customer satisfaction. In addition, according to the results of comparing customers' perception on the three levels of service quality among the ports, the Incheon Port was inferior to the Qingdo Port, the Tianjin Port and the Dalian Port in inner quality, and to the Qingdo Port and the Tianjin Port in external environment quality, but superior to the Tianjin Port and the Dalian Port in interaction quality. However, customers' satisfaction with the Incheon Port was lower than that with the Qingdo Port and the Tianjin Port.
