Statistical optimum methodology of table of orthogonal array, ANOM, ANOVA and RSM are applied to formulate optimum allocation design with design variables, allocate positions of absorbing material and the objective function, average SPL of control volume in the specific control volume of coupled vibroacoustic model in the closed system. Structural natural frequency and acoustic natural frequency of cavity are analyzed by FEM in closed system. Using BEM, average SPL of specific control volume is calculated according to the condition before use absorbing material and after use it. The effect of noise reduction is showed 5.02 ㏈<SUB>RMS</SUB> by absorbing material locates at optimal position and minimum 1.83 ㏈<SUB>RMS</SUB> and maximum 3.47 ㏈<SUB>RMS</SUB> by the table of orthogonal array. Using ANOM, ANOVA and RSM, it is possible tor sensitivity analysis of design variable which presents allocation position of absorbing material applying average SPL of specific control volume in coupled vibroacoustic model to analyze quantitative statistical analysis. And the effectiveness of statistical optimum design is verified by the comparison which is coincide less than 0.01 % between optimum solution which is predicted by 2nd order approximation polynomial and analysis result of confirming experiment to verify.

In this study, a system coupled with the nonlinear dynamic vibration absorber was modelled, and its equation of motion was analized by the harmonic balance method to obtain the amplitude ratio. And also, the stability analysis was done by the Routh Hurwitz method.<br/> In the vibration systems coupled with the nonlinear dynamic vibration absorber, the unstable region and the jump phenomenon can be ramarkably affected by the damping ratio. The stable and unstable region that obtained to differential method excellently agreed to the result of the stability analysis of Routh Hurwitz.

본 연구는 노인이 운동참여정도가 운동효과 및 건강과 체력 인식에 어떻게 영향을 미치는지를 패널데이터 분석을 통하여 알아보고자 한다. 특히 운동에 참여하는 노인이 운동에 대한 효과와 자신의 건강 및 체력을 어떻게 인식하고 있는지를 규명하기 위한 목적으로 수행되었다. 본 연구는 ‘2019 국민생활체육 참여 실태조사’ 데이터를 사용하였으며, 추출된 9,000명의 표본 중 운동에 참여하는 만 65세 이상의 노인 1,046명을 표본을 대상으로 실시하였다. 노인의 운동참여 정도에 따른 운동효과 및 건강과 체력인식의 차이를 알아보기 위하여 빈도분석, 기술통계분석, One-way ANOVA 분석을 실시하였다. 그 결과 첫째, 노인의 운동 참여 정도(운동종목, 기간, 빈도, 강도)에 따라 운동효과(신체적, 정신적, 일상생활의 도움, 의료비 절감)에는 차이가 있는 것으로 나타났다. 이를 구체적으로 살펴보면 구기 및 라켓운동에 참가하는 노인들이 신체, 정신, 일상생활, 의료비 절감효과가 가장 높다고 인식하고 있었으며, 운동참여 기간, 빈도, 강도가 높을수록 운동효과를 높게 인식하는 것으로 나타났다. 둘째, 노인의 운동 참여 정도(운동종목, 기간, 빈도, 강도)에 따라 건강 및 체력인식에 차이가 있는 것으로 나타났다. 이를 구체적으로 살펴보면, 구기 및 라켓운동 참가 노인들이 건강과 체력에 대하여 좋게 평가하고 있었으며, 운동참여 기간, 빈도, 강도가 높을수록 건강과 체력에 대한 인식이 긍정적인 것으로 나타났다. This study aims to analyze how the elderly perceive the effects of exercise. In particular, it was conducted for the purpose of finding out how the elderly participating in exercise perceive the effect of exercise and their health and physical strength. This study used the data of the '2019 National Living Sports Participation Survey', and out of the sample of 9,000 extracted, 1,046 elderly people aged 65 years or older who participated in exercise were sampled as a target. Frequency analysis, technical statistics analysis, and one-way ANOVA analysis were performed to find out the difference between exercise effect and health and physical fitness according to the degree of exercise participation of the elderly. As a result, first, it was found that there was a difference in exercise effect (physical, mental, help in daily life, medical cost reduction) according to the degree of exercise participation (exercise item, duration, frequency, intensity) of the elderly. Second, it was found that there was a difference in the perception of health and physical strength according to the degree of exercise participation (exercise type, duration, frequency, intensity) of the elderly.

본 연구는 외국인 유학생들의 우울 수준을 평가하고, 우울수준에 따른 이야기 그림검사(Draw A Story: DAS)의 반응특성을 분석하여, 이야기 그림검사가 유학생들의 우울을 평가하는 선별도구로서 활용될 수 있는지를 검증하고자 하였다. 이를 위해 충남 소재 S대학에 재학하는 학생 중에서 편의 표집으로 선택된 한국인 학생 113명과 외국인 학생 55명을 대상으로 우울진단검사(BDI)와 DAS 그림검사를 배포하여 총 168부를 회수하여 본 연구의 자료로 사용하였다. 수집된 자료는 SPSS 25 통계프로그램에 의해 ANOVA분석, 상관분석 그리고 교차분석을 실시하였다. 연구결과는 다음과 같다: 첫째로 외국인 유학생들은 한국인 대학생들에 비하여 더 높은 비율로 우울을 경험하는 것으로 나타났다. 둘째로, 우울수준에 따라 DAS 그림검사 점수간의 관계를 분석한 결과 우울한 집단이 비우울집단 그리고 가벼운 우울집단에 비하여 정서내용척도와 자아상 척도에서 유의미한 차이가 있는 것으로 나타났다. 셋째로, 우울수준에 따라 DAS 그림검사의 자극 그럼 선택에서 차이가 있는지를 분석한 결과, 유의미한 차이가 발견되지 않았다. 이와 같은 결과는 DAS 그림검사가 외국인 유학생의 우울을 평가하는 선별도구로서 유용하게 활용될 수 있다는 것을 보여주고 있다. This study intended to verify whether the Draw-a-Story (DAS) test can be used as a screening tool for evaluating the depression of international students by evaluating the level of depression of international students and analyzing the responsive characteristics to DAS test based on their level of depression. 113 Korean students and 55 international students, selected through convenient sampling, among the students enrolled in University S in Chungcheongnam-do were given the Beck Depression Inventory (BDI) and DAS test and a total of 168 copies were retrieved and used as the material for this study. The data collected were put under ANOVA, correlation analysis, and cross analysis by using SPSS 25 statistics program. The result is as follows; First, international students experienced depression at a higher rate than Korean students. Second, the analysis of the relationship between DAS test score and the level of depression showed that the depression group had significant difference in emotional content scale and self-image scale compared with non-depression group and mild depression group. Third, the analysis on whether there is a difference in selecting stimulative pictures in DAS test according to depression level did not show significant difference. These results indicate that DAS test can be useful as a screening tool for evaluating the depression level of international students.

This paper deals with the correlation between the interior noise and the floor vibration of the train from rolling, impulse and friction in Busan Metro line 3. The correlation is verified by sound and vibration measurement causing friction between the railway and the wheel. If ANC(Active Noise Control) system can reduce 5 dB in below 500 Hz, the sound pressure level of the whole band pass can be reduced about 1.8-4.8 dB in squeal noise. Curve squeal noise is the intense high frequency tonal that can occur when a railway vehicle transverses a curve. The frequency range is from around 500 to almost 20,000 Hz, with noise levels up to about 15 dB in curve.

This paper deals with the buckling and vibration analysis of plate with a hole. As aspect ratio rises in design parameter, the buckling strength and the natural frequency of laminated composite plate decrease and as diameter of hole for width of plate rises, the buckling strength decrease but the natural frequency increase. Also this paper tried to realize the optimum ply-angle with maximum buckling strength and natural frequency of laminated composite plate.
