In KSC 3706, the gymnasiums are classified according to their size(small, medium, large) and there are two kinds of illumination arrangement method for them such as Side and Distributed. The characteristic of the distributed illumination arrangement method is excellent in uniformity and the characteristic of the side illumination arrangement method is excellent in glare. but illuminations were so diverse that features are not always applicable. So in this paper, in this paper, We analyzed characteristic of distributed illumination arrangement method and side illumination arrangement method using nine illumination.

The seismic responses of small-scale spatial frames such as school gymnasiums are usually evaluated using static analysis, although time-history analysis should be carried out to fully incorporate the dynamic responses of the structures against seismic motions. In this study, advanced static analysis procedures arc presented for school gymnasiums that will improve the performance evaluation against seismic motions. The seismic loads are approximated by equivalent static loads corresponding to the two performance levels; i.e., Levels 1 and 2 defined by the Japanese building standard. The importance of utilizing the eigenmode in the load pattern is discussed. Simple static analysis procedures are presented for evaluation of maximum vertical acceleration. It is shown that the static analysis for Level 2 input significantly underestimates the responses by dynamic analysis; however, the inelastic responses for Level 2 are shown to be successfully evaluated using the equivalent linearization that is similar to the $^{\circ}$Dmethod based on calculation of limit strength$^{\circ}{\pm}$ for building frames in Japan.

This study shows that the Argovian Cantonal School in Aarau, Switzerland, which Albert Einstein attended from 1895 to 1896, had been closely related to the ideological education controversy in German Gymnasium throughout the 19th century. Due to this controversy, Einstein hardly received a formal science education in Bavaria. Despite the lack of formal education in Germany, he had a habit of self-studying from an early age and continued with this practice all through his life. He had a hard time at the authoritarian school in Munich, but at the democratic school in Aarau, where freedom and autonomy were secured, he was able to achieve emotional stability. For a long time, the city Aarau prevailed as a location of tolerance and multi-culturalism, without religious, regional, and national discrimination. This was possible due to the influence of external and unrestricted social mobility, as well as the Enlightenment from France. As a result, this small public school was able to acquire a mass of qualified human resources from outside of Switzerland. As a consequence of the controversy regarding the educational ideology, the Cantonal School adopted practical thoughts and the Enlightenment that fit the spirit of the times. The school consisted of two independent educational organizations: the Gymnasium, where the 'neuhumanistsch' education for the elite training was conducted, and the 'Gewerbeschule', where a more realistic education system was set up to suit the citizen life. In particular, after 1835, the Gymnasium changed gradually from the pure humanistic education to the 'utraquistisch' ways by introducing practical subjects such as natural history. Thereafter, the Cantonal School became an institution that was able to achieve a genuine humanity, academic, and civic life education. Einstein, who attended the 'technische Abteilung' of the 'Gewerbeschule,' considered this school as a role model of an institution that realized true democracy, and that left an unforgettable impression on him.

The purpose of this study is to examine the residents' preference to community facilities in national rental apartment complexes. Twelve housing complexes were sampled and researched with questionnaire and field-surrey methods. The data from the questionnaire survey were processed with SPSS 14 and analyzed by regional group, size of complex, and arrangement plan of facilities. The complexes are located in two legions, Seoul and Gyounggi province. They were also sorted into three groups by size: less than 500 households, 500 to 1,000, and more than 1,000. Lastly, the complexes were categorized into three types: those where facilities are concentrated in or around a single building, dispersed into several places, and located in residential buildings. The results are as follows: Majority of the community facilities are established outdoor and, therefore, the indoor facilities are relatively more insufficient. Especially, there is a shortage of indoor gymnasium while the demand is increasing. It is partly because there is no regulatory guideline on indoor gym requirements in housing complexes. The resident satisfaction measurement shows significant comparison according to region and complex size. The level of satisfaction with garden/kitchen-garden, pond/fountain/streamlet is higher at the complexes in Gyunggi. The residents of larger complexes give positive feedback about spells facilities while those of smaller complexes are more satisfied with education-related facilities such as library and study. The measurement of resident needs shows significant comparison according to complex size and facility arrangement plan. The residents of smaller complexes are more in need of community facilities. In both regulatory standards and actual condition, community facilities are more insufficient at small complexes with less than 500 households.

The Educational Cultural Center for Students is a new mixed-cultural space which made around 1997 for students' education of humanism and talent with the 7th revision of educational course. This Educational Cultural Center for Students is different to the existing one because the subject of the culture is students who make creation and performance by themselves while the former ones were for seeing, hearing and feeling things. There are seven Educational Cultural Center for Students all over the country and will be built more in the future. Comparing to the former Educational Cultural Centers for Students, functional rooms in the Educational Cultural Centers for Students are an outdoor performance room, a large performance room, a small performance room of performance facility, a gallery of display facility, a gymnasium, a swimming pool, a fitness room, a table-tennis room of physical facility, a library and a reading room of a book facility, and a group room, a computer room, a singing room, a billiard room, an art room, a musical room, a dancing room, a manner room, a playing room, a cultural lecture room and a seminar room of a interest-activity facility. The result of analyzing the usage frequency is that a performance room has the highest frequency and a display room, a musical room, a music appreciation room and a physical room follow the frequency order. But this frequency does not fit for all area. By place and social situations, the frequency and space organization may be changed.

As technology advances, the need for enhanced preparedness against cyber-attacks becomes an increasingly critical problem. Therefore, it is imperative to consider various circumstances and to prepare for cyber-attack strategic technology. This paper proposes a method to solve network security problems by applying reinforcement learning to cyber-security. In general, traditional static cyber-security methods have difficulty effectively responding to modern dynamic attack patterns. To address this, we implement cyber-attack scenarios such as 'Tiny Alpha' and 'Small Alpha' and evaluate the performance of various reinforcement learning methods using Network Attack Simulator, which is a cyber-attack simulation environment based on the gymnasium (formerly Open AI gym) interface. In addition, we experimented with different RL algorithms such as value-based methods (Q-Learning, Deep-Q-Network, and Double Deep-Q-Network) and policy-based methods (Actor-Critic). As a result, we observed that value-based methods with discrete action spaces consistently outperformed policy-based methods with continuous action spaces, demonstrating a performance difference ranging from a minimum of 20.9% to a maximum of 53.2%. This result shows that the scheme not only suggests opportunities for enhancing cybersecurity strategies, but also indicates potential applications in cyber-security education and system validation across a large number of domains such as military, government, and corporate sectors.
