Schools have developed together with local communities, as leading public buildings that represent local communities. Most elementary schools are located in walking distance, so that makes it possible to maintain close relationships with local residents. This study examine outside space where the school buildings are restructured for new images through public park project. The results of this research as follows. 1st, Public park project of school facilities is charge of key role to improve urban image. 2nd, Public park project of school facilities promote environmental, social and educational participation of school members. 3rd, We need to develop a outside space plan and to gather diverse opinions before we start on the Public park project of school facilities. 4th, It is important to maintain the space desirable through sharing of roles by members of schools and local communities. Public park project of school facilities has to be the center of participation, process, commune and practical use.

This paper proposes a parking space detection method for autonomous parking by using the Around View Monitor (AVM) image and Light Detection and Ranging (LIDAR) sensor fusion. This method consists of removing obstacles except for the parking line, detecting the parking line, and template matching method to detect the parking space location information in the parking lot. In order to remove the obstacles, we correct and converge LIDAR information considering the distortion phenomenon in AVM image. Based on the assumption that the obstacles are removed, the line filter that reflects the thickness of the parking line and the improved radon transformation are applied to detect the parking line clearly. The parking space location information is detected by applying template matching with the modified parking space template and the detected parking lines are used to return location information of parking space. Finally, we propose a novel parking space detection system that returns relative distance and relative angle from the current vehicle to the parking space.

Global map of solar surface magnetic field, such as the synoptic map or daily synchronic frame, does not tell us real-time information about the far side of the Sun. A deep-learning technique based on Conditional Generative Adversarial Network (cGAN) is used to generate farside magnetograms from EUVI $304{\AA}$ of STEREO spacecrafts by training SDO spacecraft's data pairs of HMI and AIA $304{\AA}$. Farside(or backside) data of daily synchronic frames are replaced by the Ai-generated magnetograms. The new type of data is used to calculate the Potential Field Source Surface (PFSS) model. We compare the results of the global field with observations as well as those of the conventional method. We will discuss advantage and disadvantage of the new method and future works.

The purpose of this study is to clarify the actual condition of external space general high schools newly established or planned in Gyeongnam from 2001 starting the 7th curriculum to 2006. The results of analysis about site plan type, composition state of external space and area ratio of its composition of each high school facilities are as follows: 1) In facilities arrangement of high schools, it shows diverse forms of arrangement from existing uniform straight type, however, most of schools do not being against the simple in their external space. 2) Comparing to traditional high school facilities, it occurs various types of plane and the area is somewhat expanded in the school with same class size, however, it needs to improve facility standards in its reality to deal with the change of future educational environment actively.

In order to make good educational circumstance of the Technical High-school, it is important that we must aware of the characteristics of technical high-school and take all considerations into the planning. This study is to plan the architectural space and path of flow in practice rooms through questionnare survey. The result are as follow. A majority of respondents recognize that the existing facility and space condition are not appropriate, because the past investment has overemphasized on the quantitative aspect. It is time to need the change of its directions toward the quantitative investment in future. It is also necessary to plan the space and the path of flow of the practice rooms in consideration of the characteristics of school.

The most powerful technique for deducing the magnetic structure of the Sun is spectro-polarimetry. Detailed measurements of the polarization signal of the spectral lines (Stokes vector) allow us to infer the physical conditions in the solar atmosphere prevailing during the line formation. Inversion codes are the main tool to extract this information from the Stokes spectra. This study will focus on measurements of the chromospheric He I 1083.0 nm triplet and the photospheric Si I 1082.7 nm line. A spectropolarimetric data set of sunspots, obtained with the German Vacuum Tower Telescope (VTT) at the Teide observatory on Tenerife, is analyzed using an inversion technique. We will introduce the German Vacuum Tower Telescope and the inversion code HeLix, and will show data sets that are analyzed by HeLix.

Our school management is changing by soft and self-regulating method from single educational system. Especially, 7th educational curriculum demands change of educational system and operation that correspond spontaneously on various needs of students. Like this, changing educational policy and curriculum accompany change of social awareness, curriculum, and school space should be changed corresponding hereupon. Such our change can say that is appearing fairly similarly, when compare in Japanese educational policy, curriculum, side of change of school space. Because it is resulting from partial accepting of educational curriculum, system, school architecture and space of Japan. In such background, I investigates Japanese schools cases that advanced than us, which is been opened within the latest 6 years. Through this analysis, I find space and function that can apply to our school. And I will propose some basic data needed for educational and architectural planning side.

A bipolar magnetic field perturbation in the meridional plane was observed when the Polar spacecraft crossed the plasmapause near the midnight, which was identified by a clear jump in density and temperature, from the plasmasheet to the plasmasphere. The bipolar variation shows a negative-then-positive polarity. To examine the bipolar magnetic field perturbation at the plasmapause, we assume one-dimensional model with physical quantities varying along a direction normal to the plasmapause and employ two-fluid approach for the tangential plasmapause. That is, the magnetic fields on both sides are parallel. Considering Ampere's law and pressure balance relation, we have a perturbed magnetic field, which is consistent with the observation at the plasmapause.

We present near-infrared spectroscopic results for three nearby class I sources, IRAS 03445+3242, IRAS 04239+2436 and ESO $H{\alpha}$ 279a. We detected many molecular and atomic line emissions, e.g., $H_2$, [Fe II], Hydrogen Bracket series recombination, Ca I, Na I & CO overtone band, from these sources using the high-resolution Immersion GRating INfrared Spectrometer (IGRINS; R~45,000). Previous studies showed that all the three sources posses actively accreting Keplerian disks. We performed spectral analysis to understand the origin of Hydrogen Bracket series recombination lines. We also estimated the accretion properties and mass loss rates of circumstellar disks for all the three sources.

In this study, we generate future full disk magnetograms in 12, 24, 36 and 48 hours advance from SDO/HMI images using deep learning. To perform this generation, we apply the convolutional generative adversarial network (cGAN) algorithm to a series of SDO/HMI magnetograms. We use SDO/HMI data from 2011 to 2016 for training four models. The models make AI-generated images for 2017 HMI data and compare them with the actual HMI magnetograms for evaluation. The AI-generated images by each model are very similar to the actual images. The average correlation coefficient between the two images for about 600 data sets are about 0.85 for four models. We are examining hundreds of active regions for more detail comparison. In the future we will use pix2pix HD and video2video translation networks for image prediction.
