Seismologists now suggest that the earth has entered an active seismic period; many earthquake-related events are occurring globally. Consequently, numerous casualties, as well as economic losses due to earthquakes, have been reported in recent years. Primarily, significant and colossal damage occurs in reinforced concrete (RC) buildings with masonry infill wall systems, and the construction of these types of structures have increased worldwide. According to a report from the Ministry of Education in the Republic of Korea, many buildings were built with RC frames with masonry infill walls in the Republic of Korea during the 1980s. For years, most structures of this type have been school buildings, and since the Pohang earthquake in 2017, the government of the Republic of Korea has paid close attention to this social event and focused on damage from earthquakes. From a long-term research perspective, damage from structural collapse due to the short column effect has been a major concern, specifically because the RC frame with a masonry infill wall system is the typical form of structure for school buildings. Therefore, the short column effect has recently been a major topic for research. This study compares one RC frame with four different types of RC frames with masonry infill wall systems. Structural damage due to the short column effect is clearly analyzed, as the result of this research is giving in a higher infill wall system produces a greater shear force on the connecting point between the infill wall system and the column. The study is expected to be a useful reference for research on the short column effect in RC frames with masonry infill wall systems.

According to the Gyeonggi Provincial Office of Education's 2018 Education Statistics, there are 4,692 schools in Korea, and most of them were built before 1985 and the aging of facilities due to earthquake and external environment has reached a serious point and are vulnerable to safety. The Gyeonggi Provincial Office of Education designated 2,561 buildings with floor space of 1,000 square meters or more under the "Special Act on Safety and Maintenance of Facilities (2018.1.18. Full Revision)" and conducted regular safety inspections. The purpose of this study is to analyze the evaluation of school facilities according to the results of a regular safety inspection and to propose a maintenance plan for educational facilities for future defects according to the conditions of the facilities.

In Seowon architecture, there are four kinds of space conditions according to the site plan and the figure of education area. The education area has three main buildings such as Kangdang, Dongjae, Seojae. In case Kangdan locates in front of Dongjae and Seojae(so called Junkangdang-Hoojaesa), but in another case Dongjae and Seojae locates in front of Kangdang(so called Junjaesa-Hookangdang). This four space conditions affect to decide the floor plan and the window & door system of Kangdang. In Junjaesa-Hookangdang type, the front and rear wall has more open system than in Junkangdang-Hoojaesa type. In Junjaesa-Hookangdang type the direction of Kangdang is absolutely open to front education area, but in Junkangdang-Hoojaesa type the direction of Kangdang is absolutely open to rear education area. These floor plan aims at making up education area more closely. In window & door system the rear parts of Junjaesa-Hookangdang type have generally opaque system such as Golpanmoon or Panjangmoon, but Junkangdang-Hoojaesa type breaks this rule in order to emphasize front facade of building.

Emission factors for ammonia and particulate matters (PMs) from livestock buildings are of increasing importance in view of the environmental protection. While the existing emission factors were determined based on the emission inventory of other countries, in situ measurement of emission factors is required to construct an accurate emission inventory for Korea. This study is to report measurements of ammonia and PMs emissions from mechanically-ventilated pig houses, which are common types of pig barns in Korea. Ventilation rates and concentrations of ammonia and PMs were measured at the ventilation outlets of a weaner unit, a growing pig unit and a fattening pig unit to calculated the emission factors. The PMs emission was characterized with different aerodynamic diameters (PM_2.5, PM₁₀, and total suspended particulates (TSP)). The measured ammonia emission factors for weaners, growing pigs and fattening pigs were 0.225, 0.869 and 1.679 kg animal^-1 yr^-1, respectively, showing linear increase with pigs' age. The PMs emission factors for three growing stages were 0.023, 0.237 and 0.241 kg animal^-1 yr^-1, respectively for TSP, 0.017, 0.072 and 0.223 kg animal^-1 yr^-1, respectively for PM₁₀, and 0.011, 0.016 and 0.151 kg animal^-1 yr^-1, respectively for PM_2.5. PMs emissions were increased with pigs' age due to increasing feed supply and animal movement. The measured emission factors were smaller than those of the existing emission inventory indicating that the existing ones overestimate the emissions from pig buildings and also suggesting that long-term in situ monitoring at various livestock buildings is required to construct the accurate emission inventory.

Background: The study investigated the causes of safety accidents by facility, focused on safety accidents caused directly or indirectly by school facilities at elementary schools in S City. Purpose: The objective of this study is to provide materials for planning the construction of school buildings and the installation of school facilities and for improving existing facilities and ultimately to minimize mental and Physical losses from safety accidents caused by school facilities and to create pleasant education environment. Method: We selected 10 elementary schools in S City, analyzed the factors of safety accidents caused by facilities inside and outside the schools, and presented the results of the analysis including the factors of safety accidents caused by elementary school facilities. Result: It was found that safety accidents caused by elementary school facilities can be prevented to some degree by considering safety accidents in facility planning. As the safety accident rate is higher at elementary schools than at middle and high schools, it is essential to consider safety accidents in planning the construction of an elementary school and to execute safety accident prevention education in order to reduce safety accidents at elementary schools. In addition, as the curriculums are revised and new facilities are introduced for the new curriculums, elementary students' physical, psychological and environmental factors should be analyzed and studied closely and the results should be reflected in establishing the standards for the installation of elementary school facilities.

It is a well-known fact that most of the Korean school buildings has been adjusted by the standard plan according to the united and unified teaching method ever since the modern education started. However, seeing the recent growth of care for the open education, the effort to improve the teaching method in school fileds, the practice of the 6th education plan and the education reformation, it can be said that it is high time to change. As the number of schools which practice the open education has been increasing since in 1985 in this atmosphere, there have also appeared elementary schools with the open school building. But the general understanding of the school building and the open space is not enough. Therefore, this study aims to analyze the general spacial conditions, such as the fresh and diverse types of learning method and their development and the concept of the open space along with its types, application, size, and constition by studying, from the standpoint of the building plan, the elimentary schools of a new type in Japan which adopted the open space 20years earlier than in Korean. This study can offer helpful suggestions as to the Korean school building because our situation is very similar to the early stage where the open space is adopted to the school building.

The analysis of the progressive collapse resistance of structures is a well-known issue among structural engineers. Large-span reticulated dome structures are commonly utilized in large public buildings, necessitating research into their progressive collapse resistance to assure user safety. The most significant part of improving the structural resilience of reticulated domes is to evaluate their key elements. Based on a stiffness-based evaluation approach, this work offers a calculating procedure for element importance coefficient. For both original and damaged structures, evaluations are carried out using the global stiffness matrix and the determinant. The Kiewitt, Schwedler, and Sunflower reticulated domes are investigated to explore the distribution characteristic of element importance coefficients in the single-layer dome structures. Moreover, the influences of the load levels, load distributions, geometric parameters and topological features are also discussed. The results can be regarded as the initial concept design reference for single-layer reticulated domes.

The determination of the fundamental period of vibration of a structure is essential to earthquake design. Current codes provide formulas for the approximate estimation of the fundamental period of earthquake-resistant building systems. These formulas are dependent only on the height of the structure or number of storeys without taking into account the presence of infill walls into the structure, despite the fact that infill walls increase the stiffness and mass of the structure leading to significant changes in the fundamental period. Furthermore, such a formulation is overly conservative and unable to account for structures with geometric irregularities. In this study, which comprises the companion paper of previous published research by the authors, the effect of the vertical geometric irregularities on the fundamental periods of masonry infilled structures has been investigated, through a large set of infilled frame structure cases. Based on these results, an attempt to quantify the reduction of the fundamental period due to the vertical geometric irregularities has been made through a proposal of properly reduction factor.

This study begins with paying attention to the agglomeration of 'Residential-Commercial Mixed Use Buildings(hereafter, R-C MU Buildings)', which tend to be a high grade and large sized building cluster at various neighboring areas in Seoul. The purpose of this study is to understand the relationship between emerging new housing type and residential area by analyzing the characteristics of residential neighborhood that is mainly created by R-C MU Buildings. For this purpose, the specialization and the regional characteristics(in connection with the hierarchy in urban spatial structure) of R-C MU Building's residential neighborhood were analyzed. In the end, the specific type of housing reveals the tendency to be differentiated in terms of income, education and occupation related with housing and residential area. And the residential characteristics also seem to be different according to the regions based on the central place hierarchical structure. It means that the social and class factors are important in choosing house, but the characteristics of the neighborhood area play an important role in the selection of resident area. Finally, the location of certain type of housing can influence the selecting process of residence and it can also determine the characteristics of the resident area in turn.
