Purpose - The purpose of this study is to find out research directions for distribution and fusion and complex field to many domestic and foreign researchers carrying out related academic research by confirming research trends in the Journal of Distribution Science (JDS). Research Design, Data, and Methodology - To do this, I used keywords from a total of 904 papers published in the JDS excluding 19 papers that were not presented with keywords among 923. The analysis utilized word clouding, topic modeling, and weighted frequency analysis using the R program. Results - As a result of word clouding analysis, customer satisfaction was the most utilized keyword. Topic modeling results were divided into ten topics such as distribution channels, communication, supply chain, brand, business, customer, comparative study, performance, KODISA journal, and trade. It is confirmed that only the service quality part is increased in the weighted frequency analysis result of applying to the year group. Conclusion - The results of this study confirm that the JDS has developed into various convergence and integration researches from the past studies limited to the field of distribution. However, JDS's identity is based on distribution. Therefore, it is also necessary to establish identity continuously through special editions of fields related to distribution.

Installation of sensors networks for continuous in-service monitoring of structures and their efficiency conditions is a current research trend of paramount interest. On-line monitoring systems could be strategically useful for road infrastructures, which are expected to perform efficiently and be self-diagnostic, also in emergency scenarios. This work researches damage detection in composite concrete-steel structures that are typical for highway overpasses and bridges. The techniques herein proposed assume that typical damage in the deck occurs in form of delamination and cracking, and that it affects the peak power spectral density of dynamic curvature. The investigation is performed by combining results of measurements collected by long-gauge fiber optic strain sensors installed on monitored structure and a statistic approach. A finite element model has been also prepared and validated for deepening peculiar aspects of the investigation and the availability of the method. The proposed method for real time applications is able to detect a documented unusual behavior (e.g., damage or deterioration) through long-gauge fiber optic strain sensors measurements and a probabilistic study of the dynamic curvature power spectral density.

Objective: The aim of this study is to investigate haptic perception related researches into three perspectives: cutaneous & proprioceptive sensations, active & passive touch, and cognition & emotion, then to identify issues for implementing haptic interactions. Background: Although haptic technologies had improved and become practical, more research on the method of application is still needed to actualize the multimodal interaction technology. Systematical approached to explore haptic perception is required to understand emotional experience and social message, as well as tactile feedback. Method: Content analysis were conducted to analyze trend in haptic related research. Changes in issues and topics were investigated using sensational dimensions and the different contents delivered via tactile perception. Result: The found research opportunities were haptic perception in various body segments and emotion related proprioceptive sensation. Conclusion: Once the mechanism of how users perceives haptic stimuli would help to develop effective haptic interactrion and this study provide insights of what to focus for the future of haptic interaction. Application: This research is expected to provide presence, and emotional response applied by haptic perception to fields such as human-robot, human-device, and telecommunication interaction.

The jeans fashion has important meaning as the symbol of sociocultural phenomenon related with modern fashion. It became the symbol of natural fashion beauty representing freedom and equality and sometimes the sensual style. This study defined the meaning, element, and importance of fashion styling by analyzing preliminary studies and analyzed the aesthetic characteristics of the jeans fashion. The purpose of this study is to drive four styling patterns of the jeans fashion based on such theoretical studies and empirical researches about jeans fashion and plan and direct jeans fashion styling for each style. The results also provides the basis for acknowledging that the idea of 'directing and creating a style' according to a person's intent beyond the one-dimensional idea of simply 'wearing' clothes is the true fashion styling and will set an important footing in the fashion field with the ideas that fit the 21st century.

Objectives The purpose of this research is to comprehensively analyze about Jowiseungcheong-tang (Diàowèishēngqīng-tāng). This herbal medicine is widely used to treat obesity and metabolic disease. Methods We used 3 search terms, 'Jowiseungcheong-tang', 'Jowiseungcheong-tang plus obesity' and 'Jowiseungcheong-tang plus metabolic disease' in Korean word via 5 domestic databases. Therefore, 8 laboratory experiments and 4 clinical researches were chosen. Results Jowiseungcheong-tang (Diàowèishēngqīng-tāng) was identified as a herbal medicine for obesity and related metabolic disease. In plasma level of lipid, leptin, inflammatory material were decreased in laboratory experiments. Weight loss and symptom relief were reported in clinical research. Conclusions Definite information about laboratory experiment was showed, specifically suitable index and numerical value. In clinical research, although Jowiseungcheong-tang (Diàowèishēngqīng-tāng) is widely used for obesity and metabolic disease, the number of reported thesis and patient were pretty a few. Also, diagnosis methods were also scanty. Multi-institutional clinical trial should be progressed.

In many applications, received signal strength indicator is used for location tracking and sensor nodes localization. For location finding, the distances between sensor nodes can be estimated by converting received signal's power into distance using path loss prediction model. Many researches have done the analysis of power-distance relationship for radio channel characterization. In indoor environment, the general conclusion is the non-linear variation of RSSI values as distance varied linearly. This has been one of the difficulties for indoor localization. This paper presents works on indoor RSSI characterization based on statistical methods to find the overall trend of RSSI variation at different places and times within the same room From experiments, it has been shown that the variation of RSSI values can be determined by both spatial and temporal factors. This two factors are directly indicated by the two main parameters of path loss prediction model. The results show that all sensor nodes which are located at different places share the same characterization value for the temporal parameter whereas different values for the spatial parameters. Using this relationship, the characterization for location estimation can be more efficient and accurate.
