The purpose of this study was to examine the differences and the relationship between basic psychological needs and exercise addiction and to identify effects of To do this, the data were collected using the self-evaluating questionnaires on the exercise addiction, the of basic psychological needs, and the subjective were distributed to 305 participants in general exercise enthusiast for all, and the collected data. This study used the SPSS Statistics 18.0 program to process data. Exploratory factor analysis was performed for validity and Cronbach's α was performed for reliability. In addition, Frequency Analysis was carried out to analyze the demographic characteristics and Pearson's Correlation Analysis, independent t-test, one-way ANOVA, correlation analysis, multiple regression analysis Analysis were performed to verify the correlations and differences among variables. The significance level in this research was set at=.05 and the followings α are derived outcomes. The following is the comprehensive finding of the effect of general exercise enthusiast exercise addiction through basic psychological needs. First, there was no significant difference in basic psychological need and Exercise Addiction of general characteristics, but participation in 6 days was the highest in exercise amount per week. Second, Basic Psychological Need(autonomy, competition, relatedness) showed a high difference in Exercise Addiction(withdrawal symptoms, exercise need, emotional attachment). Third, correlation analysis between all variables showed statistically significant difference. Fourth, Basic Psychological Need(autonomy, competition) was found to have a high effect on Exercise Addiction(withdrawal symptoms, exercise need, emotional attachment).

The purpose of this study was to examine the effects of whole-body vibration exercise for life care on balance and walking ability in the fall risk stroke patients. 30 stroke patients were divided into two groups, Otago exercise group(n=15) and whole-body vibration exercise group(n=15). Walking ability were measured by 10m walking and Tinetti mobility test with stroke patients and balance ability were measured by BBS and TUG on comparative analysis of pre, post exercise. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that BBS and Tinetti mobility test of the both groups were increased statistically significantly and TUG and 10m walking test of the both groups were decreased statistically significantly. balance ability and walking ability of the whole-body vibration exercise group were improved statistically significantly in comparison with those of the Otago exercise group. The results of this study showed that whole-body vibration exercise for the improvement of life care had significant effects on improving BBS, TUG, 10m walking and Tinetti mobility test of fall risk stroke patients. Therefore, it is recommended to apply whole-body vibration exercise to improve life-care through improving balance ability and walking ability of fall risk stroke patients.

This study attempted to investigate the effect of competitive anxiety on injury psychology according to the athletic career of tennis athletes at Chinese universities. To study the method, 208 athletes enrolled in a four-year university (0 university, 0 university) located in A City, Hanam Province, were surveyed for a total of three weeks from the end of January to the beginning of February 2023. To verify the research model, frequency analysis, exploratory factor analysis, reliability analysis, and correlation analysis were conducted using SPSS Statistics 25. And independent sample t-test and one-way ANOVA were conducted to find out the differences in variables according to general characteristics, and multiple regression analysis was conducted to verify hypotheses through the concept of measurement. As a result of the study, first, it was found that there was a significant difference in the athletic career of tennis athletes at West China University. Second, the non-standardized coefficient of competition anxiety was found to have a positive (+) effect on exercise weaponry. Third, the non-standardized coefficient of competition anxiety was found to have a positive (+) effect on anxiety and anxiety. Therefore, it was found that other competitive anxiety in the exercise career had an effect on injury psychology. Since competition anxiety according to the athletic career of tennis athletes at Chinese universities affects injury psychology, it suggests that a psychological program that can control competition anxiety and injury psychology of athletes should be developed and introduced to athletes.

리니어 발전기는 리니어 엔진의 시동에 필요한 연소조건을 만들기 위하여 전동기로 동작하다가 연소가 안정화되면 발전기로 동작을 하여 PCS(Power Conditioning System)를 통해서 전력을 계통으로 보내주게 된다. 리니어 엔진의 초기 시동을 하기 위하여 발전기는 운동주파수와 운동방향, 그리고 힘의 크기를 제어해야 하며, 발전 시에는 엔진의 동작에 맞도록 전력을 제어해야 한다. 이를 효율적으로 제어하기 위하여 MSC(Machine Side Converter)에서 상전류를 독립적으로 조절할 수 있는 H-bridge로 각 상을 구성하였다. LSI(Line Side Inverter)는 DC-Link 전압을 제어하여, MSC의 동력/발전 동작에 따라서 전력을 계통에서 받아오거나 전력을 계통으로 보내는 동작을 한다. 본 연구에서는 리니어 발전기 모델링를 통해서 PCS 제어 알고리즘을 확인하고 전체 시스템과 연동을 한 실제 운전특성에 대하여 살펴보았다.

Objectives: Periodic leg movements in sleep (PLMS) might be subdivided based upon whether or not they are associated with visible EEG microarousals (MA). MA is considered to be responsible for nonrestorative sleep and daytime fatigue. The American Sleep Disorders Association's (ASDA) scoring rules for MA based on visual analysis of the EEG changes suggest that MA should last more than 3 seconds. However, it has been suggested that visual analysis may not detect some changes in EEG activity. This study is aimed at measuring changes in EEG spectra during PLMS without MA in order to better understand the arousing response of PLMS. Methods: Ten drug-free patients (three men and seven women) diagnosed with PLMS by polysomnography were studied. Spectral analysis of the EEG was performed in each patient on 30 episodes of PLMS without MA, chosen randomly across the night in stage 2 non-REM sleep. We applied stricter criteria for MA compared to ASDA, by defining it as a return to alpha and theta frequency lasting at least 1 second. Results: The mean PLMS index was $16.7{\pm}10.0$. The mean PLMS duration was $1.3{\pm}0.7$ seconds. Comparison of 4-second EEG activity both before and after the onset of PLMS without MA using independent t-test showed that the movements were associated with significant increase of relative activity in the delta band (p=0.000) and significant decrease of activity in the alpha (p=0.01) and sigma (p=0.000) bands. No significant decrease in the theta (p=0.05), beta (p=0.129), or gamma (p=0.062) bands was found. Conclusion: PLMS without MA was found to be associated with EEG change characterized by increase in the delta frequency band. This finding seems to be compatible with the hypothesis of an integrative hierarchy of arousal responses of Sforza's. Considering that the subjects had lower PLMS index and shorter PLMS duration than those of the previous study, it is suggested that an even less severe form of PLMS without MA could induce neurophysiologic change, which may potentially be of clinical significance.

This task is to derive the Hamiltonian equations of motion for BMW 323i vehicle. The kinematic relationships are defined. The cut constraint equations are derived. The cut constraint equations are stabilized. The stabilized constraint equations are used to derive the relationships between the independent and dependent coordinates. The Hamiltonian equations of motion are reduced only in terms of the independent generalized coordinates.

광복절이 있는 8월은 우리 역사에 대해 많은 생각을 하게 한다. 일제강점기 동안 강탈당한 나라를 되찾기 위해 목숨을 걸었던 독립운동가의 숭고한 기개가 오늘을 사는 우리를 다시 한 번 숙연하게 하기 때문이다. 몽양 여운형은 일제강점기와 해방전후기 가장 합리적인 민족지도자로서 조선 광복과 대한민국 건설에 기여한 지대한 공로를 인정받아 지난 2008년 2월 최고 훈장인 건국훈장 대한민국장에 추서됐다. 여인성 대중기계(주) 대표이사가 몽양의 종손자인 것은 익히 알려진 사실이다. 프린팅코리아가 여 대표를 만나 친족만이 전할 수 있는 몽양의 위대한 발자취를 밝히고, 8월의 의미를 다시 한 번 되새겨본다.

당뇨병성 족부질환은 크게 당뇨병성 족부 혈관병증, 당뇨병성 족부 신경병증, 당뇨병성 족부궤양 등으로 나누어지며, 당뇨병환자에서 하지에 궤양 및 괴사가 발생 위험도는 정상인에 비하여 15~17배나 높다. 이러한 당뇨병성 족부질환을 제대로 치료하지 않으면 발의 일부나 전부를 절단하게 되며, 외상에 의한 절단을 제외하면 하지 절단의 가장 주요한 원인이 된다. 당뇨병성 족부질환으로 인해 불가피하게 절단이 되었다 하더라도 수술 직후부터 적극적인 약물치료 및 재활치료는 정상인과 거의 동일하게 일상생활 수행 및 독립보행이 가능하며, 스포츠를 포함한 여가활동까지 가능하다.
