With today's new media environment throughout Ubiquitous information innovation, live and dynamic fluid space is being created by integrating organic integration between electronic space and physical space and transplanting intelligence to materials. In other words, perception occurs in fluid space itself in a new media environment so has complicatedly organic relationship with environment and humans. In addition, emotion, time and movement have actively attempted to enter the space so designs appealing to humans' emotions are made through stimulation of synaesthetic sensory organs. This can be understood in the same context that media is eventually expansion of human body. Fluid space has characteristics of a live organism with factors such as sensor, perception and behavior so it needs to interpret perceptual system relationally and synthetically through an organic study method. This study looks into characteristics of organic perceptual system in terms of the meaning that fluid space with movements have as the sensory-perceptive subject and accordingly makes the world more sufficient as the third space, prepares a possibility to get out of limited five senses, and will develop fluid space as the organic environment making stimulation by itself.

The purpose of this study was to investigate the effects of mass media and personal factors on attitudes towards plastic surgery and plastic surgery behavior. For this study the personal factors included concern for appearance, self-esteem, and body satisfaction. Subjects were 472 college students in Ulsan. The results showed that favorable attitudes towards plastic surgery were a little higher than the median, meaning that the respondents had a slightly positive attitude towards plastic surgery, and only 20% of the respondents had had an experience with plastic surgery. A multiple regression analysis was computed and indicated that a more positive attitudes towards plastic surgery was related to high levels of concern for appearance, more time watching TV, a higher household income, and being a female student, in terms of gender. The results of logit analysis indicated that a more positive attitude towards plastic surgery and being a female student related to a higher probability of having had plastic surgery.

Purpose: This study was to examine the fitness of a path model based on the objectification theory and to expand it by including the new variables to explain eating disorder symptomatology (EDS). Methods: The subjects consisted of 444 college women. Data was collected through self-report questionnaires that measured self-objectification (SO), social physique anxiety (SPA) and EDS as the original variables in the objectification theory, and influence of mass media (IMM) and sex-role attitude (SRA) as the new variables. Data was analyzed by SPSS/WIN 12.0 and Amos 5.0 programs. Results: IMM and SRA showed direct effect on SO. IMM had direct and indirect effect on SPA and EDS. SRA had direct and indirect effect on EDS, but only indirect effect on SPA. SO and SPA influenced EDS directly, and SO influenced indirectly EDS. Conclusion: Path analyses indicated support for the original theory and the expanded theory. It is necessary for repeated studies including various age groups of women to clarify the applicability of the objectification theory to Korean women's eating disorders. And it were recommended that we should promote womens' criticism of the image and message about the perfect female body presented in the mass media, and to highlight the relationship of gender equality to women's eating disorders in health education.

In this paper, we present electroencephalography (EEG)-based power spectra analysis and auditory stimuli methods as coping mechanisms for disgust affection and phobia. Disgust affection is a negative emotion generated from trying to eliminate something harmful to one. It is usually related to mental illnesses such as obsessive-compulsive disorder, specifically phobia and depression. In our experiments, participants watched videos on horrible body mutilation and disgusting creatures, with either the original sound track or relaxing and exciting music as auditory stimulation. After watching the videos with original sound track, the participants watched the same video with a different audio background, such as soothing or cheerful music. We analyzed the EEG data utilizing relative power spectra and examined survey results of the participants. The results demonstrated that disgust affection is decreased when participants watched the video with relaxing or exciting music instead of the original soundtracks. Moreover, we confirmed that human's brainwave reacts according to types of audio and sources of disgust affection.

This study was undertaken to examine the feasibility of black locust (Robinia pseudoacacia) as substrates for several edible mushrooms. For the cultivation of several edible and/or medicinal fungi on black locust, optimum bulk densities, synthetic or semisynthetic additives, natural additives and pretreatment methods were investigated. Fruit body yields of the fungi on various sawdust media composed of different wood species were also analyzed for testing the capability of black locust as a substrate for mushroom production. Mycelial growths decreased proportional when the bulk density increased. The most suitable carbon and nitrogen sources as additives to promote the mycelial growth were sucrose (2%, w/w) and ammonium phosphate (0.2%, w/w) respectively. When corn-powder and beer-waste as natural additives were added to sawdust of black locust showed the significant growth of mycelia. And the optimum mixing ratio was 10:2:1 (sawdust: corn-powder: beer-waste, w/w). Black locust after cold water treatment showed the outstanding mycelial growths. Any significant changes of pH, moisture content (%) and dry-weight losses (%) could not be found among culture substrates (sawdust of black locust, oak and poplar wood) examined before and after harvesting of fruit bodies. Yield of fruit bodies on black locust culture media were comparable with those culture media composed with oak and poplar wood. The present work indicated strongly the potentiality of black locust as raw materials for edible and medicinal mushrooms.

The specific anthropomorphic mannequin (SAM) phantom was designed to provide a conservative estimation of the actual peak spatial specific absorption rate (SAR) of the electromagnetic field radiated from mobile phones. However, most researches on the SAM phantom have been based on early phone models. Therefore, we numerically analyze the SAM phantom to determine whether it is sufficiently conservative for various types of mobile phone models. The peak spatial 1- and 10-g averaged SAR values of the SAM phantom are numerically compared with those of four anatomical head models at different ages for 12 different mobile phone models (a total of 240 different configurations of mobile phones, head models, frequencies, positions, and sides of the head). The results demonstrate that the SAM phantom provides a conservative estimation of the SAR for only mobile phones with an antenna on top of the phone body and does not ensure such estimation for other types of phones, including those equipped with integrated antennas in the microphone position, which currently occupy the largest market share.

The purpose of the study is to investigate how uptake counts of $^{201}Tl$ of radioisotopes in the human body could change, when taking computed tomography and magnetic resonance imaging right after injecting contrast media. $^{201}Tl$ radioisotope substances of iodine contrast medium, which is a computed tomography contrast medium, and paramagnetic contrast medium, which is an magnetic resonance imaging contrast medium, were used as study materials. First, $^{201}Tl$ was put into 4 cc of normal saline in test tube, and then a computed tomography contrast medium of Iopamidol$^{(R)}$ or Dotarem$^{(R)}$, was put into 2 cc of normal saline in test tube. An magnetic resonance imaging contrast medium of Primovist$^{(R)}$ or Gadovist$^{(R)}$ was also put into 2 cc of normal saline in test tube. Each contrast medium was distributed to make $^{201}Tl$ as 3 mCi, with a total of 4 cc. Gamma camera, low energy high resolution collimator, and pinhole collimator were used to obtain images. The uptake count of $^{201}Tl$ was measured with 1000 frames of images, and obtained after 10 times of repetition. This study revealed that the use of Gadovist$^{(R)}$, which is an magnetic resonance imaging contrast medium, showed the smallest number of uptake count, after measuring $^{201}Tl$ uptake count by low energy high resolution collimator. On the other hand, the use of Iopamidol$^{(R)}$, which is a computed tomography contrast medium, showed the biggest difference in uptake count, when measuring $^{99m}Tc$ uptake count by Pinhole collimator. When examining with gamma camera, using contrast medium and $^{201}Tl$, identifying the changes of uptake count is very important for improving the value of diagnosis.

This study started with the question "Shall we apply the existing record management method to our trivial daily records?" For the general public, we focus on media that thinks more about daily recordings and suggests a better method, suggesting a 'social platform' as a plan, and using the user's visual approach through UX design methodology. The social archive proposed in this study aims to be a 'square' where various people can gather and communicate and share. A space that can record daily life using 'record' as a basic body Purpose It aims to provide the basis for basic research in various fields, and aims to function as a space for communication of various research things such as researchers and researchers, researchers and producers. In order to maintain, focus on the prerequisites of the existing construction, the items to be researched when constructing the daily archive are 'creative methodology to change research items when building a paradigm', 'network with related organizations', 'service plans for persistence', and characteristics of social media. We discussed the possibility of social media as a social archive platform. Finally, while looking at the user experience design process, I designed some features of the social archive and suggested things to do in UX design.

Objective: Optimizing culture media for the incubation of immature oocytes is a vital strategy to increase the oocyte maturation rate during in vitro maturation (IVM) programs. This study evaluated the IVM and fertilization rates of human germinal vesicle (GV) and metaphase I (MI) oocytes using two different maturation media (commercial and homemade) with or without growth differentiation factor 9-β (GDF9-β). supplementation. Methods: Immature oocytes from intracytoplasmic sperm injection (ICSI) cycles were collected and assigned to one of two IVM culture media (commercial or homemade; cleavage-stage base). After maturation, MII oocytes were examined under an inverted microscope for the presence of the polar body, zona pellucida (ZP) birefringence, and meiotic spindle (MS) visualization after maturation in four conditions (commercial or homemade medium, with or without GDF9-β. ICSI was done for matured oocytes, and fertilization was confirmed by the visualization of two distinct pronuclei and two polar bodies. Results: No significant differences were found between the two culture media in terms of the time and rate of oocyte maturation or the rate of fertilization (p>0.05). Growth factor supplementation increased the 24-hour maturation rate for both GV and MI oocytes only in homemade medium. The maturation rate after 24 hours was higher for MI oocytes (p<0.05). Similar results were observed for MS visualization and ZP structure in both types of media (p>0.05). Conclusion: Higher rates of oocyte maturation and fertilization were observed after application of homemade medium supplemented with GDF9-β. Therefore, this combination may be recommended as an alternative for clinical IVM programs.
