Growing plant in potting media without soil is known as Soilless cultivation. This method is used mostly in greenhouse cultivation to increase horticultural commodities production. Peat moss is commonly utilized as potting media substrate because of its characteristic. However, peat moss price is high because of the quantity of peat moss in nature has been decreased. Recently, most of the research is conducted to find the alternative growing medium to cultivate horticulture plant in potting media. Perlite and rice husk ash were mentioned that had a potent as alternative growing media for seasonal plants to increase agriculture production due to the lack of production area. This research aims to determine the growth of in rice husk ash, perlite and peat moss as growing substrates. The method used was the soilless cultivation. The chinese cabbage was planted in the pot with perlite media, rice husk ash media, and peat moss media. The chinese cabbage was measured after 35 days after planting. The result showed that peatmoss was more potentials in chinese cabbage growth performance than rice husk ash and perlite. Peat moss had the significant result of every research parameters such as plant height, plant weight, number of leaves, plant diameter, root length, and root weight. The best alternative for cultivation chinese cabbage without substrate based on this research was peat moss then rice husk ash and perlite.

This study aims to propose three universal appropriate conditions, 'difference', 'planning', and 'freshness' for convergence products, and research their contents. 'Difference' means that combined functions have to be all different. 'Planning' indicates that combining different functions has to be proceeded in product development processes, so multiple usages human beings make in their daily lives have to be excepted. 'Freshness' explains that the values of combined functions are expanded by convergence. They are the elements to represent convergence products' functional characteristics and developing processes. They widen the range of convergence products by making in a number of various combining ways, and develop a lot of discourses based among social cultural backgrounds, concepts, and products. This study has shown that convergence is a product method that is managed by strict plans, strategies, and chosen functions. Convergence is a product development method with chosen functions, strict plans, and development strategies. Now, this study will lay the foundation for future works on product development strategies based on convergence.

This study investigates in depth of the new marketing trend, in which social media, an effective marketing tool for promoting a new product, and gamification technic of engaging consumers in communication, are combined. Although gamification has been applied to various fields for a long time, conventional way of applying gamification is different from when it is combined with socialmedia. Therefore, this study examines the background and characteristics of the convergence phenomena between the social media and gamification based on the theoretical consideration of the social media and gamification. Then, the cases of social media marketing utilizing gamification are analyzed and classified into general participation, active participation, creative behavior, networking, and experiential type according to the user's different levels and ways of participation. As a result, when the social media and gamification are combined, the change of an aspect is found to be more meaningfully influential to today's consumers as in competition - achievement - relationship, compared to the conventional way of game mechanics. This study has significance in the way that it established a useful basis for the marketing strategy through the study of the new game mechanics that has been applied to social media marketing utilizing gamification.

The convergence of media poses serious challenges to technologies, industries and policy makers. At the core of the challenges lies a socially and culturally problematic condition of 'media unlimited.' Under the circumstances, the idea of public interest of the media seems to lose its intervening leverage as it flounders in countering 'the media torrent' rushing from the exponential growth of ICTs that overwhelms contemporary life and society. It is an urgent task for the critical community to blaze fresh new thoughts about the idea to intervene in the current age of media excess. Beyond the conventional content-conduit-centered perspective on the media, this study suggests a media-environment concept based on media ecology as an engaging leverage to replenish the public interest idea. The environmental approach to the media means literally to conceptualize the media as environment--a cultural eco-system. This study explores the potential of ecological approach in enriching the conceptual terrain of policy discussions and policy-making processes concerning the public interest idea that hopefully enlightens all the media actors concerned.

In the past decade, deep learning has been applied to various medical image analysis tasks. Skeletal bone age estimation is clinically important as it can help prevent age-related illness and pave the way for new anti-aging therapies. Recent research has applied deep learning techniques to the task of bone age assessment and achieved positive results. In this paper, we propose a bone age prediction method using a deep convolutional neural network. Specifically, we first train a classification model that automatically localizes the most discriminative region of an image and crops it from the original image. The regions of interest are then used as input for a regression model to estimate the age of the patient. The experiments are conducted on a whole-body scintigraphy dataset that was collected by Chonnam National University Hwasun Hospital. The experimental results illustrate the potential of our proposed method, which has a mean absolute error of 3.35 years. Our proposed framework can be used as a robust supporting tool for clinicians to prevent age-related diseases.

In the Fourth Industrial Revolution era, with its accelerating radical changes and innovation, fashion is rapidly advancing to sustain social changes introduced by technological convergence. In light of this, the study investigates the social and cultural characteristics of technologizing fashion products: creative modifications emerge from technological convergence with fashion products and result in a realm separate from technology. By focusing on the nature of fashion, this study analyzes the technologization of fashion products for added value creation in the fashion system. Based on the findings, it interprets different attitudes toward technologizing that changes fashion products. Accordingly, this study reviews previous literature and qualitatively examines empirical cases based on inductive reasoning. In particular, it analyzes commercialized cases of fashion-technology convergence in fashion products found on online fashion media outlets between January 2007 and May 2021, a central period in intellectual and technological innovation. The characteristics of technologized fashion products are identified as follows: expansion of physical functions and categories, interaction with emotional sensibilities, artistry through combination with technologies, and computer-generated imagery(CGI) fashion as digital goods. Therefore, this study analyzes the characteristics of technologization, focusing on the social and cultural properties of fashion products. The findings provide opportunities to understand the paradigm shift of these products that was catalyzed by technologizing.

This study uses text mining compares and contrasts consumers' social media discourses on dietary related zero-waste movement before and after COVID-19. The results indicate that the amount of buzz on social networks for the zero- waste movement has been increasing after COVID-19. Additionally, the results of frequency analysis and topic modeling revealed that subjects associated with zero-waste movement were more diversified after COVID-19. Although the results of a sentiment analysis and word cloud visualization confirmed that consumers' positive responses toward the zero-waste have been increasing, they also revealed a need to educate and encourage those who are still not aware of the need for zero-waste. Finally, consumers mentioned only a small number of companies participating in zero-waste movement on SNS, indicating that the level of active involvement by such companies is much lower than that of consumers. Theoretical and educational implications as well as those for government policy-making are considered.
