In this study, we propose a wind power generation prediction system that applies machine learning and data mining to predict wind power generation. This system increases the utilization rate of new and renewable energy sources. For time-series data, the data set was established by measuring wind speed, wind generation, and environmental factors influencing the wind speed. The data set was pre-processed so that it could be applied appropriately to the model. The prediction system applied the CNN (Convolutional Neural Network) to the data mining process and then used the LSTM (Long Short-Term Memory) to learn and make predictions. The preciseness of the proposed system is verified by comparing the prediction data with the actual data, according to the presence or absence of data mining in the model of the prediction system.

This study uses digital imaging and communications in medicine (DICOM) files acquired after CT scan to obtain the absorbed dose distribution inside the body by using the patient's actual anatomical data; uses geometry and tracking (Geant)4 as a way to obtain the accurate absorbed dose distribution inside the body. This method is easier to establish the radioprotection plan through estimating the absorbed dose distribution inside the body compared to the evaluation of absorbed dose using thermo-luminescence dosimeter (TLD) with inferior reliability and accuracy because many variables act on result values with respect to the evaluation of the patient's absorbed dose distribution in diagnostic imaging and the evaluation of absorbed dose using phantom; can contribute to improving reliability accuracy and reproducibility; it makes significance in that it can implement the actual patient's absorbed dose distribution, not just mere estimation using mathematical phantom or humanoid phantom. When comparing the absorbed dose in polymethly methacrylate (PMMA) phantom measured in metal oxide semiconductor field effect transistor (MOSFET) dosimeter for verification of Geant4 and the result of Geant4 simulation, there was $0.46{\pm}4.69%$ ($15{\times}15cm^2$), and $-0.75{\pm}5.19%$ ($20{\times}20cm^2$) difference according to the depth. This study, through the simulation by means of Geant4, suggests a new way to calculate the actual dose of radiation exposure of patients through DICOM interface.

In recent years, the quality requirements from the customers of hot rolled steel strip have been steadily increasing in diversity and strictness. To meet these quality requirements as well as to improve productivity, steel mills have been doing their efforts for developing high performance Automatic Gauge Control (AGC) system. However, it is very time consuming and also needs a lot of money to develop the new technologies of AGC in actual mill. So, there has been a demand for developing the Dynamic Hot Rolling Simulator since late 80's. It is a kind of software packages and can analyze the dynamic behaviors of hot finishing rolling process without laborious experiments in actual mill. It can also be used as a designing tool of Automatic Gauge Controller. In this work, the Dynamic Hot Rolling Simulator which is applicable to 6 sands hot strip mill rolling was developed. The MATLAB with SIMLINK was used as a software developer for making the main part of simulator because it is very powerful tool for modeling, integrating, controller design, and simulation. In this paper, the structures and the mathematical models of the simulator were briefly described and the results of simulation on the transient phenomena of hot rolling process with actual mill data were also presented.

The purpose of this study is to suggest objective basic data for park management proposal through the quantitative analysis of users' needs and satisfaction for the actual conditions of management in Moaksand provincial park. For this, users' needs and satisfaction for facilities have been analyzed. And user's satisfaction for the actual conditions of management had been analyzed by using the multiple regression. Users want more toilets and sign boards and to replace damaged facilities. Users gave thought to trail and had high pressure to improvement, and many users were uncomfortable by crowding, and had a positive view to restrict use of intensity. Systematic careful concern about trail and rest area should be need and periodic observation to change of facility condition also. According to the multiple regression analysis, the major variable to the satisfaction for the actual condition of facilities management was trail ground condition.

The earth station antenna operating on a GEO communication satellite is influenced by sun interference in the period of the spring or the autumn eqinox. Such phenomena are also undertaken by ray-bending phenomena in atmosphere. Therefore the prediction time of sun interference does not theoretically match actual interference time. In this paper, the actual sun interference time has been analyzed in consideration of ray-bending phenomenon, the size of main reflector of earth station antenna and elevation angle between an earth station antenna and a satellite. Ray-bending phenomenon in atmosphere is proved to be disregarded if the Mugungwha satellite is luanched in 1995. The analysis results are compared with actual measurement values of sun interference time at local earth stations and the two data are in accord well.
