This study was carried out to develop the best medium of new oyster mushroom for bottle culture. The new oyster mushroom cv. Miso is a Pleurotus ostreatus developed at the Chungnam Agricultural Research & Extension Services. For the bottle culture media, poplar sawdust+beet pulp+cottonseed meal (5:3:2), poplar sawdust+wheat husk meal (8:2), poplar sawdust+beet pulp+cottonseed meal (6:2:2), poplar sawdust+beet pulp+cottonseed meal (4:4:2), and poplar sawdust+beet pulp+wheat husk meal (7:1:2) were used in 850cc PP bottle. The pH was 5~6 and the C/N ratio 19.7~28.3 in bottle culture media. The time of pinhead formation was 5 to 6 days. For the fruiting body formation after inoculation took 29~31 days. The yield of fruiting body of poplar sawdust+beet pulp+wheat husk meal (7:1:2) medium was the highest at 110.4g/bottle compared to other media. Therefore, such cultivation medium would be appropriate for the commercial production of bottle culture in the new oyster mushroom 'Miso'.

Ion concentrations and osmolarities of the body fluid and oxygen consumption of the larvae of the freshwater crab, Eriocheir japonicus under the influence of various salinities and water temperatures were studied. The levels of $Na^+\;and\;Cl^-$ ions in the body fluid of the crab placed in the low salinities (freshwater and $30\%$ seawater) were higher at the low temperature $(16^{\circ}C)$ than high temperature $(30^{\circ}C)$. However, the crab in the high salinity $(90\%\; seawater)$, those ions in the body fluid were higher at the high temperature $(30^{\circ}C)$ than the low temperature $(10^{\circ}C)$ When the zoea larvae were young (first and second stages), the ion concentrations of the body fluid were more affected by salinities and temperatures of the media. The salinity levels of the media more influenced the levels of $K^+$ ions of the body fluid of the larvae than the temperature. The osmolarities of the body fluid of the larvae were almost isotonic when they were placed at $70\%$ seawater $(24.5\%o)$. Oxygen consumption of individual larva was lower in zoea 1 and 2 stages than the other stage larvae. The high oxygen consumption of the larvae was observed at $70\%$ seawater compared to the other salinity levels.

In recent, projection mapping, which has attracted high attention in the field of realistic media, is regarded as a technology to increase the users' immersion. However, most existing methods perform projection mapping on static objects. In this paper, we developed a technology to track the movements of users and dynamically map the media contents to the users' bodies. The projected media content is built by predefined gestures just using the user's bare hands without the special devices. An interactive immersive media system has been implemented by integrating these dynamic projection mapping technologies and gesture-based drawing technologies. The proposed realistic media system recognizes the movements and open / closed states of the user 's hands, selects the functions necessary to draw a picture. The users can freely draw the picture by changing the color of the brush using the colors of any real objects. In addition, the user's drawing is dynamically projected on the user's body, allowing the user to design and wear his t-shirt in real-time.

These days, with the advent of digital broadcasting, media environment offers users an opportunity to enjoy differentiated contents in a more aggressive fashion through user-media interactions based on computer technology. In fact, the development of contents which can induce spontaneous acts from users such as outdoor ads which use certain sensors and devices and exhibition halls has been active. With the development of low-price motion recognition devices, people have been able to enjoy diverse interaction-applied media by recognizing users' motion data without body contact. In this paper, we developed an interactive media player that can recognize the user's motion and control the video in the web service environment without installing a specific program. In addition, we set user motion recognition range and developed a user motion recognition algorithm suitable for the Leap Motion equipment installed in the kiosk. The results of this study can be experienced by various interactive media such as interactive tourism, education, and movie contents in kiosks that can be installed in public places.

BACKGROUND/OBJECTIVES: Coronavirus disease 2019 (COVID-19) cases were first reported in December 2019, in China, and an increasing number of cases have since been detected all over the world. The purpose of this study was to collect significant news media reports on food services during the COVID-19 crisis and identify public communication and significant concerns regarding COVID-19 for suggesting future directions for the food industry and services. SUBJECTS/METHODS: News articles pertaining to food services were extracted from the home pages of major news media websites such as BBC, CNN, and Fox News between March 2020 and February 2021. The retrieved data was sorted and analyzed using Python software. RESULTS: The results of text analytics were presented in the format of the topic label and category for individual topics. The food and health category presented the effects of the COVID-19 pandemic on food and health, such as an increase in delivery services. The policy category was indicative of a change in government policy. The lifestyle change category addressed topics such as an increase in social media usage. CONCLUSIONS: This study is the first to analyze major news media (i.e., BBC, CNN, and Fox News) data related to food services in the context of the COVID-19 pandemic. Text analytics research on the food services domain revealed different categories such as food and health, policy, and lifestyle change. Therefore, this study contributes to the body of knowledge on food services research, through the use of text analytics to elicit findings from media sources.

This study intends examine the relevance of factors with negative influences on anti-social sexual awareness formation in adolescents as per the concern of the parents of families with adolescents, as internet pornography exposure in adolescents lead to excessive indulgence in pornographic photographs, cartoons, videos, or fictions, or in video chatting with exposure of one's own body parts. For this, the factors of internet pornography exposure in the study subjects of adolescents were constructed into a multilateral model, and the structural equation model was analyzed. As the result of the study, the following conclusion were drawn. First, the most powerful factor influencing the anti-social sexual awareness in adolescents was, contrary to the concern of many, not the exposure to pornography through internet media, but personal characteristics such as sensation-seeking tendency and socio-environmental characteristic of differential association. Second, it is worth noting that the most major factor influencing intentional internet pornography exposure by adolescents is another form of pornography exposure. Third, whether intentional or unintentional, the internet-related variable influencing the internet pornography exposure was found to be the amount of internet usage. Fourth, the unintended internet pornography exposure was found to have no direct influence on the sexual awareness of adolescents, but it did have an indirect influence on sexual awareness mediated by intentional internet pornography exposure and existing-media pornography exposure. Based on these study results, the conclusion was drawn regarding the influence of internet pornography on sexual awareness in adolescents.

This paper presents a direct seek control algorithm for swing-arm type dual stage servo system that consists of a coarse actuator and a fine actuator. The proposed scheme is to design a control system that attenuates the effect of dynamic coupling between the two actuators so that the seek operation can be performed in a single-shot with stability. In an optical drive system with dual stage servo mechanism, the effect of dynamic coupling between the two actuators needs to be handled during the coarse seek operation due to its inherent structure. In an extreme case, the two actuators can collide each other, which leads to critical degradation of the seek performance. To handle this problem, our proposed control scheme is to generate the drive signals such that the two actuators behave as if they are a single fixed body. To this end, a feedforward controller and two feedback controllers are designed that enable the current drive system perform wide range of track seek. Simulation results are provided to show the validity and feasibility of our proposed algorithm.

Language and letter are represented by a combination of its signifier and signified. All symblos are commonly calling direct attention to people who are living in the physical world. However, in cyberspace, the image takes control once inhabited by the language. Cyberspace with anonymity and deoent physical nature has something with physical laws. In this space the statue transcends the imaginary realm. Ideology gives a greater connotation by giving a series of regulation to images floating in cyberspace. Even if various media have the same image, the meaning of the image changes depending on which ideology is used. The impact of this on the public is great. In this study, I discuss the ideology in cyberspace where is supposedly wide open to who visits and spreads all the thoughts without suppression and the human body. The main ideas would be who owns the ideology and what does it want to control and how the people would react to the ideology. This paper would eventually head the prototype that visualizes above ideas. Though the interactive media it will also show the subject in the real world is accept the images floating in the cyberspace without any doubts.
