This study is designed for analyzing the mechanical properties of cement mortar with kind of water, sludge content for the water, mixing proportion and open time of recycling water. And this study is aimed for presenting the reference data in practical use. For the results of this study, the flow properties of fresh mortar and the strength of compresive of hardened mortar is increased until the sludge content 4.5~6.0, but is decreased after the sludge content of that.

The nation's birthrate has been rapidly falling. The purpose of this study was to explore the factors related to low birthrate, by analyzing TV dramas dealing with childbirth and rearing. Content analysis is well suited to research probing widespread cultural notions or behavior. If any part or all of the dramas discussed an aspect of childbirth and rearing, we recorded verbatim quotes and paraphrased some specific points. Using the technique of multiple observers, inter rater as well as intra rater reliabilities were measured. The results showed that emergent themes in TV dramas on low birthrate are social environment, family context, and value changes. The conclusions and implications of these findings are discussed.

Although natural and science museum project is being promoted, performance of research that can be recommended for exhibition space plan is not sufficient. Nature and science museum is the space of participation type so structure and type of space depends on the content of exhibition. Therefore, this paper is the gradational research to understand correlation and characteristic and give direction for exhibition space plan suitable for system of exhibition content through analyzing system of exhibition content and structure of exhibition space. Further, prepare basic material for exhibition space of nature and science museum being newly planned or renovated through understanding structure of exhibition space according to exhibition scenario.

Five low molar ratio urea-formaldehyde (LUF) resins were synthesized in this study. The effects of molar ratio, free formaldehyde content, and catalysts on the curing characteristics of LUF resins were studied by measuring its free formaldehyde content, pH value change after catalysts added, curing rate, and pot life, observing its cured appearance, and analyzing its thermal behavior. The results indicate that: 1) The LUF resin with lower molar ratio than 1.0 can still cure; 2) Free formaldehyde content is not the main factor in affecting curing rate of LUF resin; 3) Compared with ammonium chloride as a traditional catalyst, persulfate salts markedly accelerate the curing rate of LUF resin, and result in the different appearance; 4) the addition of sodium chloride to catalysts can accelerate the curing rate of LUF resin, but the effect is moderate.

Biodegradability of poly $Poly({\gamma}-benzyl L-Glutamate)/poly(ethylene oxide)/Poly({\gamma}-benzyl L-Glutamate)$ block copolymer (GEG) having different content of poly(ethylene oxide) (PEO) were examined using magnetite as a tracer in mice. GEG microspheres containing magnetite were injected into mice through tail vein. Biodegradability and tissue distribution of microspheres were examined by analyzing the amount of magnetite in the microspheres recollected from mice organs after specific time interval. The results showed that GEG microsphere of high content of PEO was degraded more rapidly than those of low content of PEO in the mice organs.

The purpose of this study was analyzing with present conditions and content analysis of the parking area for the handicapped people. The researcher investigate to that establishment ratio, accessibility, the induction and guidance, and safe walking passage security, and proper space of the parking area for the handicapped people was established by lawfully. The results as follows. In spite of the regulation established by law, regulations was not established 40% on region government. The parking area for the handicapped people established Properly consider to the accessibility. But the size and height of the stand-up guide plate of the induction and guidance which corresponds in legal establishment standard of the handicapped people. then this research analyzes problems and suggests alternatives of the facilities.

Objectives : The aim of this study was to observe variation of Bee Venom content from the collection period. Methods : Content analysis of Bee Venom was rendered using HPLC method by standard melittin Results : Analyzing melittin content using HPLC, 478.97mg/g at june , 493.89mg/g at july, 468.18mg/g at August and 482.15mg/g was containing in Bee Venom at september. So the change of melittin contents was no significance from June to September. Conclusion : Above these results, we concluded carefully that collecting time was not important factor for the quality control of Bee Venom, restricted the period from June to September.

Recently, IP (Intellectual Property) films have attracted much attention in the Chinese film market. This raises the need to take intellectual property films seriously in academic terms. The purpose of this study is to explore the effective methodology of content development based on intellectual property by analyzing the recent trend of Chinese intellectual property films. Recently, the driving force of the development of Chinese intellectual property films was analyzed, and the trend of Chinese intellectual property films was analyzed. The results of this study criticized the fragmented problems caused by the development of intellectual property films. This study made practical and academic suggestions to contribute to the healthy development of the intellectual property film market.

AI technology is spreading not only to industrial fields, but also to culture, art, and content fields. In this paper, we proposed a system based on AI technology that can automate the process of reproducing contents using characters for movie contents. After creating the basic appearance of the character by using the StyleGAN2 model from the video extracted from the movie contents, analyzing the character's personality and propensity using the extracted dialogue data, it was determined from the contemplative appearance based on the yin-yang and five elements to the character's propensity. Accordingly, the external characteristics are reflected in the character. Using the OpenPose model, a character's motion is created, and the finally generated data is integrated to reproduce the content. It is expected that many movie contents can be reproduced through the study of the proposed system.

The effect on learning satisfaction was compared and analyzed according to the interaction of learners in non-face-to-face classes. 38 students enrolled in the Department of Chemistry Education at G University in Gyeongnam were selected for the study. As a result of analyzing the change in learning satisfaction according to learners' interactions, positive correlations between them were shown in non-face-to-face classes. The type of classes mainly consisted of non-face-to-face real-time classes, and despite the non-face-to-face classes environment, learners focused on classes and put a lot of effort to strengthen learning. Among learners' interactions, the effect of learner-content interaction on learning satisfaction was relatively the highest, while the effect of learner-learner interaction and learner-instructor interaction on learning satisfaction was low. It was found that learners' teaching-learning in non-face-to-face classes relied heavily on learning content, and interactions with fellow learners and instructors were very limited.
