This study is to analyze works of Memphis design in the 1980s, which captured the appearance of a diversified society since the 20th century, and to present practical designs that can communicate with the public through the formulation of indoor lighting. As a research method, the background of the occurrence of Memphis groups, the theoretical background and the formative features of Memphis designs are considered around literature and prior research. The research applied Memphis's formative characteristics, colors and patterns to incorporate newly formulated designs into lighting. Lighting lamps in the forms that have made small changes to basic shapes show not only its functionality and decorability, but also its scalability as a formative language that conveys the emotions contained within humans. In addition, the choice of materials according to the changes in sculpture in the production of the work will suggest the possibility of creating a new formative art.

In order to be able to interact with the user to experience it as if it were real in virtual reality contents, input/output devices that make them feel the five senses of humans are required . In virtual reality (VR), devices that stimulate sight and hearing are the most representative. For a more realistic experience, suits and gloves that stimulate the sense of touch have recently been released, but there are not many cases applied to actual contents due to the limitation of device . In this paper, we analyze a virtual reality glove that can detect hand movement and touch in a virtual world. Based on the analysis, we propose an algorithm that can sense the intensity of collision with a VR object by tactile sense by improving the UI/UX using the vibration of the feedback method used in the existing virtual reality glove. In addition, the system implemented by the algorithm is applied to an actual case.

User interactions are being developed in various forms, and in particular, interactions using human gestures are being actively studied. Among them, hand gesture recognition is used as a human interface in the field of realistic media based on the 3D Hand Model. The use of interfaces based on hand gesture recognition helps users access media media more easily and conveniently. User interaction using hand gesture recognition should be able to view images by applying fast and accurate hand gesture recognition technology without restrictions on the computer environment. This paper developed a fast and accurate user hand gesture recognition algorithm using the open source media pipe framework and machine learning's k-NN (K-Nearest Neighbor). In addition, in order to minimize the restriction of the computer environment, a stereoscopic image control system based on user hand gesture recognition was designed and implemented using a web service environment capable of Internet service and a docker container, a virtual environment.

Most research in artificial intelligence (AI) has focused on the development of new algorithms. But as artificial intelligence has been spreading over many applications and gaining more attention from managers in the organization, academia has begun to understand the necessity of developing new artificial intelligence theories related to AI management. We reviewed recent studies in the field from 2015, and further analysis has been done for 785 studies chosen based on citation numbers of over 20. The results show that most studies have still been in the prototyping application phase of artificial intelligence across different industries. We conclude our study by calling for more research in the application of artificial intelligence in terms of organizational structures and project and risk management.

Presence of ammonia in drinking water is very toxic to human health. Soluble ammonia contaminates ground water due to activities such as the use of fertilizer in crop, industrial effluents and burning of fossil fuel. Even low concentration of ammonia present in water will damage aqua environment such as marine organism. Membrane technology is an important process to remove ammonia from effectively from water. Flat sheet membrane, membrane contactor and membrane distillation are some of the methods used for water purification from ammonia. Membrane contractor is an efficient process in which ammonia is removed through liquid-gas or liquid-liquid mass transfer without change of phase unlike membrane distillation. However, the cost of ammonia removal in this method is high due to maintenance of very high pH. Zeolite has excellent ion exchange ability that enhances its ability to interact with ammonia and adsorb from wastewater. Mixed matrix membranes containing zeolite enhance the efficiency of ammonia adsorption and separation from wastewater. In this review the above discussed issues are summarized in detail.

Among human-induced seismicity, fluid production has been one of the causes. In this report, the mechanism that causes an earthquake due to a decrease in the fluid pressure inside the reservoir during fluid extraction is summarized. As case studies, the Lacq gas field in France, the Cerro Prieto geothermal field in Mexico, and the Groningen gas field in the Netherlands, which have become issue recently, were introduced. It is showed that fluid production, ground subsidence, and the presence of existing faults were closely related with the induced seismicity. Therefore, for the development of oil or gas field and geothermal field, it is important to investigate the presence of faults that may cause earthquakes in the reservoir, to monitor ground subsidence during production in real time, and to control production.

Analysis of narrative texts has been regarded as academically and practically important, and has been made from various perspectives and methods. In this paper, the computational narrative analysis methodology from the perspective of information processing was examined. From the point of view of information processing, the creation and acceptance of narrative is a bidirectional coding process mediated by narrative text, and narrative text can be said to be a multi-layered structured code. In this paper, four methodologies that share this point of view - character network analysis, text mining and sentiment analysis, continuity analysis of event composition, and knowledge analysis of narrative agents - were examined together with cases. Through this, the mechanism and possibility of computational methodology in narrative analysis were confirmed. In conclusion, the significance and side effects of computational narrative analysis were examined, and the necessity of designing a human-computer collaboration model based on the consilience of the humanities and science/technology was discussed. Based on this model, it was argued that aesthetically creative, ethically good, politically progressive, and cognitively sophisticated narratives could be made more effectively.

The purpose of this study was to analyze the effect of university students empolyment expectation and job search burnout on job seeking anxiety. Collected data were statistically processed by PASW 18.0 program using frequency, descriptive statistics, reliability analysis, one-way ANOVA, T-test, correlation and multiple regression analysis. The results were as follows. First, it was found that university students experienced a little more anxiety about situations and causes of job insecurity than job insecurity. Second, it was found that job seeking anxiety differed according to gender, grade, monthly average household income and monthly average allowance. Third, job seeking anxiety increased more as empolyment expectations were lower and job search burnout such as inability, negative beliefs, and dehumanization were higher. Fourth, as a result of analyzing influence of variables related to job seeking anxiety, the most influential variable was inability.

The purpose of this paper is to explain the recipient's psychology, which results from the operation of media, from the perspective of the fluctuation between immersion and contemplation. Media allow to perceive and speculate about specific objects or meanings. In addition, the media perform the function of expanding or changing the objects of perception and thought. McLuhan or Luhmann's media theory emphasized this function of changing the state of perception by inducing a contemplative attitude. This notion is exemplified by interpretation of the visual media history. In this paper, the cases of film and computer game are discussed. In particular, it is considered that VR media causing strong immersion have also developed in a way that allows recipients to contemplate an virtually constructed reality. The commercialization of Tilt Brush and the experimentation of VR painting artwork are the examples for this dual development.
