Use of Statistics are involved in various stages of research such as research design at the beginning stage, determination of adequate sample size, random group allocation, data collection/management/analysis, and writing and interpretation of statistical results. As access to user -friendly statistical packages gets easier, it is more likely that wrong analyses are made due to mistakes by lack of fundamental knowledge of Statistics, which might lead to wrong study conclusions. In this paper, correct use of Statistics will be presented to prevent or minimize ethical or scientific problems.
The Use of Cinematherapy In Recreation Therapy Practice
박은식 한국디지털정책학회 2018 디지털융복합연구 Vol.16 No.2
The main purpose of this article is to explore the use of movies (i.e., cinematherapy) as a recreation therapy intervention tool. This paper begins with literature review regarding the concepts and origin of cinematherapy and introduces cinematherapy as a viable intervention option as in recreation therapy or other clinical settings. The authors provide detailed guidelines for the process of cinematherapy sessions and other practical recommendations and considerations for incorporating cinematherapy into recreation therapy practice. Guided sample questions for the debriefing stages are illustrated and lastly, examples of movies that can be used in cinematherapy suggested by recreation therapists.

본 연구는 탐지 대상물체의 형상인식이 가능한 비접촉, 원격 탐지장치의 개발에 관한 것이다. 형체인식용 비접촉 시스템은 주로 Magneto- Impedance법과 Magneto-Inductance법이 있으며, Magneto-Inductance법은 왜곡이 적고, 인체나 탐지대상탐사체에 손상을 가져오지 않는다. 본 연구에서는 2극으로 디자인 된 Magnetic Tomography System을 이용하여 탐사체의 위치에 따른 투자율 변화량을 계산 및 실측하였다. This paper describes a development of magnetic tomography system using two poles perpendicular magnetic field. In ths system, the relative permeabilities of the object are detected by Hall sensors located along with tube circumference. The signals according to the size and position of the object could be separated in case the relative permeability of the object are over 10. Moreover, the size and location of the object could be determined in real time.

본 논문에서는 GH Bladed로 선형화된 풍력 시스템의 타워 전후 방향 운동 진동저감을 목표로 제어기를 설계 한다. 타워 전후 방향 운동 모드의 감쇄비 증가를 위하여 앞섬 보상기를 설계 하고, 설계된 앞섬 보상기의 성능 검증을 위하여 계단 입력 바람과 난류 강도가 포함된 바람 입력에 대하여 각각 시뮬레이션을 수행하였다. 시뮬레이션 결과에서 타워 진동 제어기 유무에 따른 타워 전후 방향 표준편차 감소를 확인하였다. This paper presents a controller to reduce tower vibration of wind turbine system, whose model is linearized by using GH Bladed. A phase lead compensator is designed to increase a damping coefficient for a fore-aft mode of tower vibration. To validate the performance of the designed phase lead compensator, simulations are conducted for the cases of step input and the turbulent wind conditions. The results show the decrease of standard deviations in the fore-aft motion.
