This study is for the size calculation of classroom based on the size of human body and teaching tools. The curriculum of Elementary school has been changed since 1960. It has been reflected on the size of classroom of elementary school. The new education curriculum-the 7th curriculum- demands various activities in classroom. And the Ministry of Education repealed the statute about the facilities of the schools on September in 1997. So we need to different size of unit space of the classroom in elementary school because the size of classroom will affect the quality of education. It is generally known that a part of human body-size has an invariable proportion with human's status, age and weight. In this study, regression analysis is used to find out a part of human body-size of Korean. Then the size of classroom is calculated by the part of human body-size, teaching tools and the type of desk arrangement.

The purpose of this study is to derive a curriculum environment for operating various student-centered teaching and learning methods, and the following results were derived: First, most of the lectures, discussions and consultations, data search, report preparation, presentation, work exhibition, and others were commonly derived, regardless of the types of long-term and short-term project classes for each subject. In particular, the necessity of operating various classes at the same time was suggested, indicating the need for an integrated teaching and learning operation environment in the unit subject class. Second, considering that practical classes are linked concurrently to lectures and discussion classes to conduct one subject class, it is necessary to switch to a specialized curriculum system that allows various classes such as lectures to be carried out at the same time. Third, as a result of grasping the appropriateness of the space size of the subject class for realizing different class types in the future, it can be seen that the space size of the practice room, including the space for practice and the area for exhibition, should be expanded. Based on the research results, the spatial environment for the operation of future teaching and learning classes is based on the public curriculum classroom system, and whether professional curriculum classes, such as lecture rooms and discussion and presentation rooms, are secured according to the number of students.

The purpose of this study is to diagnose the problems of an elementary school care classroom in terms of facilities and physical environment and to suggest an improvement plan for building safer and more pleasant facilities and environment in further proceeding the policies of a whole-day care classroom. To this end, we analyzed the main contents of the domestic policies for elementary school care classes and the related spatial standards amongst the management plans of provincial education offices nationwide. In addition, we analyzed the relevant care facility standards of advanced countries such as the U.S., Australia, and Singapore and diagnosed the physical environmental level of Korean care classes in comparison to the international standards. Afterwards, we conducted a case study of elementary school care classes in order to examine the key issues with the environment of care classes, the causes of these issues and the user recognition and demand. The key results of this research are as follows. First, it is necessary to elaborate and refine the guidelines on elementary school care classrooms. Second, in order to provide high-quality elementary care services, it is important to have a combined classroom that can be operated at the level equivalent to or similar to a dedicated care classroom. Third, it is necessary to regularly check the facilities and environment of the elementary school care classroom.

In this paper, in order to prepare a classroom model that can effectively operate SW education, this study explored cases of creative educational space construction overseas and conducted a demand survey on elementary and middle school teachers. As a result, in overseas cases, classrooms were constructed in various forms, and furniture in the classrooms were produced in various shapes and sizes, and the cases using advanced equipment were explored. As a result of the survey on the education site, it was found that the most desired installation is a fluid type that can restructure the space by freely moving the facilities according to the teaching method. The results of the analysis are expected to be of great help in rebuilding computer labs or building infrastructure for future SW training.

This study aimed to investigate the cusp size and morphological characteristics of permanent mandibular molars in Koreans with reference to the hypoconulid, and to analyze the differences and correlations between both sexes as well as between first and second mandibular molars. We obtained data from dental casts of 110 adults (78 males and 32 females). Mesiodistal and buccolingual diameters of first and second mandibular molars, the area of five cusps (protoconid, metaconid, hypoconid, entoconid, and hypoconulid), as well as the total cusp area and occlusal table area were measured. Paired t-test was performed to analyze the morphological differences between first and second mandibular molars and the sex differences between both sexes using SPSS program. Crown diameters and cusp areas of mandibular first molars were larger than those of mandibular second molars in both sexes. The hypoconulid was the most variable in size and morphological pattern among the five cusps, and the first molars showed a higher incidence of hypoconulid than the second molars. Except for the entoconid area of the first molar (p=0.06) and the hypoconulid area of the second molar (p=0.24), all other mean values were larger in males than in females, demonstrating a significant sexual dimorphism. These data suggest that the teeth which develop late in ontogeny tend to be smaller in size and more variable in morphological characteristics.

The basic unit of school is a classroom and the aural environment of the classrooms is essential factor for education purposes. Therefore, many efforts have been undertaken for enhancing the acoustical performance of the classrooms in many countries. As a result, acoustic criteria including reverberation time and background noise level have been established in US and UK for school classrooms depending on the usage and size of the rooms. However, in Korea, there has been little researches concerning the room acoustical investigations of the classrooms. The present study investigates the current situation of the aural environment of the 15 classrooms in Korea including elementary, middle and high schools. The acoustic criteria measured include RT, $D_{50}$, STI, SNR and background noise level. As the results, it was found that the background noise levels of the schools adjacent to roads exceed the US and UK standard of 35 dB(A). Also, most schools have so low SNR that they may be interfered by noise, which may affect speech transmission. It was also revealed that some schools have longer RT than the US standard of 0.6 s, but they all have high speech intelligibility.

Anaerobic Gram-negative bacterium Prevotella intermedia is a part of normal flora of the oral cavity and associated with various types of oral and systemic diseases. We present here a draft genome sequence of P. intermedia ATCC 15032, originally isolated from cervicofacial actinomycosis. The genome is 2,848,426 bp in length and has a GC content of 43.45%. The genome includes 2,358 protein-coding genes, 5 rRNAs, and 43 tRNA. The sequence information will provide important clues in understanding the genome diversity within the bacterial species, and genetic basis for phenotypic differences among P. intermedia strains.
