BACKGROUND: Various culture media have been used for hydroponic cultures of horticultural plants under the smart greenhouses with natural and artificial light types. Management of the culture medium for the control of medium amounts and/or necessary components absorbed by plants during the cultivation period is performed with ICT (Information and Communication Technology) and/or IoT (Internet of Things) in a smart farm system. This study was conducted to develop the cloud-based data analysis system for effective management of culture medium applying to hydroponic culture and plant growth in smart greenhouses. METHODS AND RESULTS: Conventional inorganic Yamazaki and organic media derived from agricultural byproducts such as a immature fruit, leaf, or stem were used for hydroponic culture media. Component changes of the solutions according to the growth stage were monitored and plant growth was observed. Red and green lettuce seedlings (Lactuca sativa L.) which developed 2~3 true leaves were considered as plant materials. The seedlings were hydroponically grown in the smart greenhouse with fluorescent and light-emitting diodes (LEDs) lights of $150{\mu}mol/m^2/s$ light intensity for 35 days. Growth data of the seedlings were classified and stored to develop the relational database in the virtual machine which was generated from an open stack cloud system on the base of growth parameter. Relation of the plant growth and nutrient absorption pattern of 9 inorganic components inside the media during the cultivation period was investigated. The stored data associated with component changes and growth parameters were visualized on the web through the web framework and Node JS. CONCLUSION: Time-series changes of inorganic components in the culture media were observed. The increases of the unfolded leaves or fresh weight of the seedlings were mainly dependent on the macroelements such as a $NO_3-N$, and affected by the different inorganic and organic media. Though the data analysis system was developed, actual measurement data were offered by using the user smart device, and analysis and comparison of the data were visualized graphically in time series based on the cloud database. Agricultural management in data visualization and/or plant growth can be implemented by the data analysis system under whole agricultural sites regardless of various culture environmental changes.

The main aim of this article is to examine theoretical issues on the 'global-local connectivity' of regional industrial cluster and regional innovation system which have been presented since the 2000s in terms of three different aspects. Firstly, the concept of 'geographical proximity' is discussed within the context of its importance for the regional industrial development by considering relationships of cluster, local buzz and global pipeline. Secondly, concepts on knowledge gatekeeper and temporary cluster are explored with respect to their role of a mediator in forming or transforming global-local connectivity. Finally, policy implications of the global-local connection are presented. Authors arguments are as follows; firstly, in order to improve regional industrial cluster on the basis of geographical proximity, relational proximity which is beyond different spatial scales has to be secured. It means that geographical convenience and inconvenience are required simultaneously for regional industrial development. Secondly, A base of the global-local connectivity is socal capital and embeddedness. Therefore, it needs to understand that relational proximity is embedded into different culture and habit at different spatial scales. Finally, within the context of the global-local connectivity, in order to overcome spatial hierarchy by the division of labor of firms, it needs to consider the complex system which is composed of vertical and horizontal hierarchy by the spatial division of labor by firms, openness and closeness of clusters, and the scope of policies' inclusion and exclusion by central and local governments.

In this research, it was investigated the competence of Korean salesmen in the insurance business(B2C, consumer goods marketing) and information communication industry(B2B, industrial goods marketing) at the individual level rather than the organizational level. The salesperson's Guanxi ability means the salesperson's ability to create, maintain, develop the Guanxi ability. Namely, it was investigated whether the Korean salesman's Guanxi ability is the effective and persuasive concept in explaining the sales performance(company performance, business performance). The purpose of this paper was to verify which variables, among Guanxi ability and customer orientation, better explain the sales performance of salespeople. The Western concept of marketing that is closest to Guanxi is the concept of the customer-orientation that is based on the theory of relationship exchange. Confucian culture in the East is the construct concept, Guanxi is the measurement. The relational exchange theory in the West is the construct concept, customer orientation is the measurement. As the result of the analysis, we found that the Guanxi proved a greater correlation with sales performance than customer orientation. In the information technology industry, there was a big difference compared to insurance industry, whereas Guanxi and customer orientation had a similar level of correlation with sales performance. In the case of the insurance industry, we found that the Guanxi and sales performance were significant but the customer orientation and sales performance were not. This means that sales performance can be accurately and sufficiently explained only by adding the Guanxi ability in addition to customer orientation. The result of analyzing the mediating effect of the Guanxi ability between customer orientation and company performance, customer orientation was significant with Guanxi, and customer orientation and company performance were also significant. But, when the Guanxi was used as the parameter, the Guanxi was significant with company performance, but the customer orientation was not. Even when the dependent variable was business performance, when the Guanxi was used as the parameter, we found that the Guanxi was significant with the business performance, but the customer orientation was not. Namely, it proved Guanxi ability and customer orientation are completely independent concepts. In addition, we found that the information technology industry, unlike the insurance industry, mediated the Guanxi ability between customer orientation and sales performance. We confirmed that in the future, salespeople should not only rely on rational methods to maintain and reinforce customer relationships, but must consider the emotional factors through empathy with customers.

This research wanted to examine what narratives and discourse were being formed in web drama contents young generations were going crazy about. To understand the characteristics of such love epics and to know what narratives were being formed based on narrative structures and comments, this research specifically used the web drama produced up to the season 4 for the first time in Korean web drama history with a large number of accumulated views. It was found that the narratives of the drama composed the romantic relationships of four couples as independent episodes, and realistically highlighted separations and reunions of those couples, and suggested concrete methods to solve agonies and conflicts they would experience in such relationships. And, in user comments, there emerged relational narratives confusing friendship and love between partners of opposite sex, narratives regarding the third person as enemy, and narratives on typical sex roles in such romantic relations. And, the culture seeking subjective love style and sharing and sympathizing with the love histories also appeared.

The meaning and role of public space has existed based on the periodical situation like history. The more the time has passed, the faster the meaning of it has changed. We can see the differences of it from the one which used to be. This study is about Platoon Kunsthalle which is so-called the complex cultural space. The purpose of this study is to show how the user is related to the program for the planning of the public space. It is based on the procedure of the research with absorbing the place. The people who are using the space are absorbed for knowing the user's action. And then, the specific actions are written and the status of the using space is photographed. The research is based on asking and answering about that. The result of this study is as follows : The first is that young people between 20's and 30's are using a hall comparing with other age through daily using of space and features of users. Also, Using between 7p.m. and 9p.m., a dinnertime, takes the first place and using of meals and beverages is major at lunch due to restaurant and bar. User behavior of "sitting" is the biggest part and the hall is used for the public purpose connected with "talking". The second is that the daily hall space is classified with the spacial area indirectly based on the condition. Also, it depends on the time and the using. The third is that the unusual hall space is depended on the program which is the role of leading the extention of using the space. That is why the program is important because it is effected directly to the way of using the space and the place of the furniture. I am looking forward that this study is the basic data for the planning of the public space in the complicated culture.

This is the precedent study on the modern fashion design using Korean emotions, and its aim is to study the expressions in the modern fashion based on 'Jeong-Jung-Dong' idea from Korean dancing, which implicates the Korean emotion deeply among the artworks and give essence similar to the clothing. 'Jeong-Jung-Dong', a unique idea, in the Korean traditional dancing is the philosophy that involve the paradox expression, 'Movement in Silence,' which represented the emotion of Korean dancing for a long time. The main characteristics deducted in 'Jeong-Jung-Dong' were 1) the incomplete and complete by atypical, 2) the beauty of temperance by symbolism, and 3) amusing mutual relationship. Upon the analysis results of previous studies on the expressions in the modern fashion with 'Jeong-Jung-Dong', they demonstrated the atypical expressed by metaphor, symbolic expression through margin, and mutual relational table by harmony. The analysis of modern fashion expression by 'Jeong-Jung-Dong', which is a philosophical idea in the Korean dancing, could highlight the new way of looking at the clothing and systemize the theory on the Korean emotion to seek the effective expression of artistic features for the culture together with introduction of our unique emotion in the creative design process by understanding of humanitarian and philosophical ideologies to be utilized in the future Fashion Design.

This study focused on Ana Lilly Amirpour's movie 'The Bad Batch, 2016'. The core topic of the paper, 'Uncanny anthropology', was specially used in the sense of aiming for ideal anthropology, starting with the meaning of looking at Sigmund Freud's 'Uncanny' theory from 'human relationship (subject and other). The anthropology of F. W. Nietzsche, Martin Heidegger, and Emmanuel Levinas is the theoretical background of 'Uncanny anthropology', starting with Kirkegor for the discussion of a new theory of 'Uncanny anthropology'. However, this paper focused on Emmanuel Levinas' relational anthropology due to limited paper relations. The most important thing in this film is that it sublimated the malicious relationship with humans into love. He chose topics that were not routine, expressed themes and contents by disconnecting causality in the narrative, and Emmanuel Levinas' 'Uncanny anthropology' is evaluated as a film that expresses only.

The purpose of this study is to examine the effects of job stress and resilience on burnout of nurses who take care of patients with COVID-19 in prolonged pandemics. Structured questionnaires were distributed and analyzed for 162 nurses. Inadequate compensation of job stress, job demands, workplace culture, philosophical patterns of resilience, and relational patterns were statistically significant. As a result of determining the effect of job stress and resilience on burnout through the Stepwise multiple regression analysis, the final significant variable was job stress. The burnout of nurses can affect the quality of nursing services, reduced hospital competitiveness, and even quarantine systems. Therefore, this study suggests that proper compensation policy support, such as treatment of nurses and improvement of working conditions, is needed.
