In this study, we are going to derive problems for fire and safety management in multiple-user Buildings and suggest improvement measures to prevent recurrence through analysis of legal operation status for safety management of multiple-user Buildings and case studies of large-scale fires in multiple-user Buildings. For this study, first, the current state of the industry and fire occurrence status were investigated through theoretical considerations of the multi-use industry, and then the previous research on the multi-use industry was analyzed. and by analyzing the legal and institutional status of multiple-user Buildings, problems were derived through cases such as the Jecheon fire in Chungcheongbuk-do, the Inhyeon-dong fire in Incheon, and the Songpa-gu fire in Seoul. As a result, first, the necessity of strengthening the initial fire response capability. Second, thorough maintenance and management of emergency exits. Third, the need for rational regulation of upholstery. Fourth, reinforcement of fire safety education and training. Fifth, strengthening of installation standards for firefighting and safety facilities. Sixth, we derive the result that it is necessary to raise awareness about safety management, compare and analyze it with legal and institutional contents, and suggest solutions accordingly. When looking at the causes of fires in multi-use buildings, building owners, business owners, and employees think that there is no possibility of a fire occurring in their business premises, so there is a lack of awareness. It is necessary to raise awareness through education and publicity of firefighters and related administrative agencies.

Biopolymer is a versatile material used in food processing, medicine, construction, and soil reinforcement. 𝛽-glucan is one of the biopolymers that improves the soil water content and ion adsorption in a drought or toxic metal contaminated land for plant survival. We analyzed drought stress damage reduction in sweet potatoes (Ipomoea batatas L. cv. Sodammi) by measuring the growth and major protein expression and activity under 𝛽-glucan soil amendment. The result showed that sweet potato leaf length and width were not affected by drought stress for 14 days, but sweet potatoes grown in 𝛽-glucan-amended soil showed an effect in preventing wilting caused by drought in phenotypic changes. Under drought stress, sweet potato leaves did not show any changes in electrolyte leakage, but the relative water content was higher in sweet potatoes grown in 𝛽-glucan-amended soil than in normal soil. 𝛽-glucan soil amendment increased the expression of plasma membrane (PM) H⁺-ATPase, but it decreased the aquaporin PIP2 (plasma membrane intrinsic protein 2) in sweet potatoes under drought stress. Moreover, water maintenance affected the PM H⁺-ATPase activity, which contributed to tolerance under drought stress. These results indicate that 𝛽-glucan soil amendment improves the soil water content during drought and affects the water supply in sweet potatoes. Consequently, 𝛽-glucan is a potential material for maintaining soil water contents, and analysis of the major PM proteins is one of the indicators for evaluating the biopolymer effect on plant survival under drought stress.

This paper establishes and propagates the value of the play through the study of the transition process of the yesan play from 1920 to the present, presents an alternative through the unique theatricality of the region and aims to activate it. The theater divided the theater into Yecheon, Chungnam Theater Festival, and Youth Theater Festival, which are currently active, and focused on Yedang International Performing Arts Festival, which is the only one in Yesan. The details of the performance due to the loss of data were not specified as much as possible, but the contents of the yesan play before 1990 were reviewed using the eupji and Myeonji. It also starts with a lack of diversity in plays in the developing direction of Yesan. Children's plays should be dismissed for simple commercial purposes, or the value of traditional Korean plays should be compared to Western ones, to promote the development of local plays through the natural characteristics and the basis of traditional culture, and to sustain the continuity of extreme economic performance and performances through the development of repertoires. Infrastructure deployment can be cited. The in flow of specialized actors and the use of art administrators creates a stable theater environment and activates the reeducation of local actors to promote theatrical imagination. It is also an urgent task to develop a new theatrical form by introducing experimental theatrical methods of young artists in the overseas performance business of theater troupe Yechon. Finally, Yedang International Performing Arts Festival should be characterized and differentiated from other festivals.

Fiber-reinforced thermoplastic composites not only approach almost near to the strength of thermosetting composite but also has excellent productivity, recycling property, and impact resistance, which are pointed as weaknesses of thermosetting composites. The study for strength calculation of one direction fiber-reinforced thermoplastic composites and the study measuring precisely fiber orientation distribution were presented. Need the systematic study for the data base that can predict mechanical properties of composite material and fiber orientation distribution by the fiber content ratio was not constructed. Therefore, this study was investigated what affect the fiber content ratio and fiber orientation distribution have on the strength of composites. Fiber-reinforced thermoplastic composites by changing fiber orientation distribution and the fiber content ratio were made. Tensile strength ratio of $0^{\circ}$ direction of fiber-reinforced composites increased being proportional the fiber content and fiber orientation function as change from isotropy(J=0) to anisotropy(J=1). But, tensile strength ratio of $90^{\circ}$ direction by separation of fiber filament decreased when tensile load is imposed fur width direction of reinforcement fiber length direction.

This study is to carry out literary study about the subject of Martial Study in Song Dynasty which was in charge of military strategy education. Martial Examination and Martial Study were related to military officials in China, and also have important value of historical materials in physical education dealing with martial arts as traditional physical activity. To be a military official would be possible to correspond with such requirements as knowledge that sports experts should have, leadership as a leader, and ability reinforcement through physical training, and the effort to pass Martial examination as the chance of status rise contributed to developing sports and culture because the necessity of training military arts was emphasized in social situations. Martial Study establishment became a clue of creating and spreading the notion that General should have virtue and justice as an ideological style of new-Confucianism (neo-Confucianism and Sung Confucianism) in Song Dynasty. After founded in 1043 and equipped with a formal aspect in 1072, Martial Study got the political effect and improved national competitiveness while its function of cultivating and selecting excellent capable persons was going on smoothly. Educational contents in Martial Study were understanding and flexibly applying the skills of infantrymen, cavalrymen, and bowmen and the meanings and theories of confucian classics, testing problem solutions of reality, and teaching the measures of the problem. Martial Study included three aspects of military capable persons, war, and weapons and took charge of the function of education, selection, and promotion, steadily supporting development and continuance of Martial examination institution.

The present paper summarizes the results of an experimental program on the influence of using waste lathe scraps in the concrete mixture on the shear behavior of RC beams with different amounts of shear reinforcement. Three different volumetric ratios (1, 2 and %3) for the scraps and three different stirrup spacings (160, 200 and 270 mm) were adopted in the tests. The shear span-to-depth ratios of the beams were 2.67 and the stirrup spacing exceeded the maximum spacing limit in the building codes to unfold the contribution of lathe scraps to the shear resistances of shear-deficient beams, subject to shear-dominated failure (shear-tension). The experiments depicted that the lathe scraps have a pronounced contribution to the shear strength and load-deflection behavior of RC beams with widely-spaced stirrups. Namely, with the addition of 1%, 2% and 3% waste lathe scraps, the load-bearing capacity escalated by 9.1%, 21.8% and 32.8%, respectively, compared to the reference beam. On the other hand, the contribution of the lathe scraps to the load capacity decreases with decreasing stirrup spacing, since the closely-spaced stirrups bear the shear stresses and render the contribution of the scraps to shear resistance insignificant. The load capacity, deformation ductility index (DDI) and modulus of toughness (MOT) values of the beams were shown to increase with the volumetric fraction of scraps if the stirrups are spaced at about two times the beam depth. For the specimens with a stirrup spacing of about the beam depth, the scraps were found to have no considerable contribution to the load capacity and the deformation capacity beyond the ultimate load. In other words, for lathe scrap contents of 1-3%, the DDI values increased by 5-23% and the MOT values by 63.5-165% with respect to the reference beam with a stirrup spacing of 270 mm. The influence of the lathe scraps to the DDI and MOT values were rather limited and even sometimes negative for the stirrup spacing values of 160 and 200 mm.
