Objective : The purpose of this study was to investigate the changes in occupational balance and quality of life caused by COVID-19 in occupational therapy students. Methods : From May 27 to June 26, 2020, questionnaires were distributed to a total of 35 universities among 62 occupational therapy departments nationwide. General characteristics, COVID-19 related characteristics, OBQ and WHOQOL-BREF were used to evaluate and analyze occupational balance and quality of life. The SPSS/PC 24.0 program was used to analyze frequency analysis, crossover analysis, chi-square test, independent t-test, analysis of variance, and Pearson correlation analysis. Results : There were significant differences in school system(years), class, life pattern, quality of life, personal and public schedule depending on whether they are interested in occupational balance. There were significant differences in occupational balance(OBQ) and quality of life(WHOQOL-BREF), 'Hobby', 'new hobbies after COVID-19', 'life patterns', 'use of public transportation', 'maintenance of occupational balance', and 'quality of life'. There was a significant positive correlation occupational balance and quality of life. Conclusion : This study showed that the more people who have changed their lives due to COVID-19 are interested in work balance, and the better they maintain their work balance and emotional well-being, the higher the work balance and quality of life, and the positive correlation between work balance and quality of life was confirmed. This will be the basis for studies related to intervention strategies that can improve occupational balance and quality of life in a time when social isolation is easy due to the COVID-19 epidemic.

In this paper, we analyzed the effects of game-based visual feedback training on postural balance control in young adults and older adults. We provided postural balance training by 23 young adults and 14 older adults and for four weeks in fifth minute a day and three days a week using IBalance(Cybermedic Inc., Korea). We evaluated the ability of postural balance using balance SD(Biodex, medicalscience Inc., USA) for the validation of game contents based on visual feedback training program. The results showed that postural stability and limits of stability of young adults and older adults were improved significantly before and after the training(p<0.05). Thus, the games of postural balance encouraged anterior, posterior, medial, lateral and multidirectional weight shifting regarding postural balance. Our study indicates that postural balance training of visual feedback based game could be adapted for improving postural balance. Moreover, we could develope of game contents for individuals and various ages for effective application of this game-based visual feedback training.

The purpose of this study was to investigate the effect of training using unstable plate on displacement and dynamic balance ability of ankle joints in women college students wearing high heel shoes. Subjects were randomly divided into experimental group and control group. 3D motion analysis was performed while walking 9cm high-heeled shoes and walking 5m. Dynamic balanced ability evaluation was performed. The intervention program was administered to experimental subjects three times a week for four weeks. They performed balance training using unstable plates. There was no intervention in the control group. The results showed that the displacement of the ankle joints in the experimental group after the intervention was decreased overall and the dynamic balance ability was significantly increased. The control group showed little change. As a result, the training using unstable plate stabilizes the ankle joints and improves the dynamic balance ability of the subjects wearing high-heeled shoes.

The purpose of this study was to identify the effect of muscular strength, sensation, and spasticity of the hip joint on balance using clinical tools in chronic stroke patients. Thirty-two subjects participated. It were measured muscular strength of the hip flexor, extensor, abductor, and adductor using manual muscle testing, light touch sensibility, and spasticity of the quadriceps using the modified Ashworth scale in the paretic lower extremity. Also, static and dynamic balance were measured by the functional balance scale. Collected data was analyzed by stepwise multiple regression. Muscular strength of the hip abductor, light touch sensibility, and spasticity were associated with static balance(p<0.05) and explanatory power was 80.5%. Muscular strength of the hip abductor and light touch sensibility were associated with dynamic balance(p<0.05) and explanatory power was 77.9%. Thus, it is suggested that muscular strength of the hip abductor and light touch sensibility is considered when providing evaluation and intervention programs for the future in the balance.

본 연구는 뇌졸중으로 인한 성인 편마비 환자의 계단 높이에 따른 보행 훈련을 통하여 균형과 근활성도 변화를 분석하는데 목적이 있다. 뇌졸중으로 진단받은 편마비 환자 30명을 대상으로 5cm, 10cm, 15cm 높이의 계단 보행 훈련군으로 나누어 계단 보행 훈련을 실시하였으며, 임상적 균형능력 측정도구인 Berg Balance Scale(BBS), Timed up and go(TUG), Functional Reach Test(FRT)와 근활성도를 측정하였다. 연구결과 균형변화에서는 세 군간 계단 보행 훈련 전과 후의 균형 변화량이 통계학적으로 유의한 차이가 나타나지 않았으나(p>.05), 10cm 높이 계단 보행 훈련군에서 가장 큰 변화량을 보였다. 근활성도변화에서는 계단 오르기시 10cm 높이 계단 보행 훈련군에서 넙다리곧은근, 넙다리두갈래근, 장딴지근, 15cm 높이 계단 보행 훈련군에서 모든 근육들이 통계학적으로 유의한 차이를 보였으며(p<.05), 계단 내리기시 근활성도 변화에서는 5cm 높이계단 보행 훈련군에서 앞정강근와 장딴지근, 10cm 높이 계단 보행 훈련군에서 모든 근육들이, 15cm 높이 계단 보행 훈련군에서 넙다리두갈래근, 앞정강근, 장딴지근이 통계학으로 유의한 차이를 나타내었다(p<.05). 따라서, 높이에 따른 계단 보행 훈련은 편마비 환자의 임상적 균형 능력과 근활성도를 변화시키는데 영향을 줄 수 있으며, 특히 10cm 높이 계단 보행 훈련군에서는 다른 높이의 계단 보행 훈련군에서 보다 약간 상대적인 증가를 보였다.

최근의 고금리논쟁과 자본시장개방에 대응한 정책방안을 둘러싼 많은 논의의 핵심은 우리나라의 제반 거시경제여건을 반영하는 장기적 의미에서의 균형금리수준이 어느 정도인가에 대한 것이다. 장기적인 관점에서 볼 때 한 나라의 금리수준은 그 나라의 거시경제여건을 반영하는 균형금리의 추세를 반영하기 마련이며, 이러한 균형금리수준을 왜곡하는 정책 및 규제는 경제의 불안정성을 야기할 뿐, 민간부문의 규제회피노력 등으로 결국은 무력화될 소지가 높기 때문이다. 본 연구의 목적은 우리나라 금리변동의 요인 및 특성에 대해 세밀히 살펴보고, 국내외 실질금리격차의 실증분석을 통하여 그 구조적 원인을 파악하여 보며, OECD 국제비교분석을 통하여 현재 우리나라의 균형금리수준을 가늠하여 봄으로써, 향후 본격적인 자본시장개방에 대응한 통화금융정책의 모색에 하나의 지표를 제시하여 보려는데 있다. 본고의 연구분석결과에 의하면 우리나라의 명목금리는 실질경제성장률 외에도 기대인플레이션 및 경상수지적자와 밀접한 관계가 있으며, 해외금리 및 예상환율절하율도 점차 주요한 금리의 설명변수로서 나타나고 있다. 엄밀한 의미에서의 피셔효과는 기각되나 기대인플레이션이 명목 및 실질금리의 가장 주요한 변동요인으로 나타나 물가안정을 통한 인플레이션 기대심리의 불식이 향후 금리안정의 관건으로 분석되었다. 특히 통화공급의 유동성효과는 단기적으로만 나타나며 장기적으로는 오히려 금리상승을 유발하는 것으로 나타나 금리안정을 위해서는 안정적인 통화관리가 중요한 것으로 분석되었다. OECD 국제비교분석을 통하여 추정해 본 결과 우리나라의 1997년 균형금리수준은 회사채수익률 기준 약 11%대로 나타나 소폭의 금리하락 가능성이 있으나 지속적인 경상수지의 불균형 등 금리하락여건은 여의치 않은 것으로 보인다. 이미 자본시장개방이 진전된 OECD 국가들의 실증분석에서도 나타나듯이 금리의 하향안정화는 거시경제의 안정과 금융의 효율성 제고가 동시에 이루어져야만 가능한 것이다. 그러므로 향후 금리정책은 금리의 가격기능을 조속히 회복시켜 자원배분의 효율성을 극대화할 수 있는 시장메커니즘을 활성화하는 방향으로 추진되어야 할 것이다.

The fundamental endeavor of this study is to investigate the asymmetric relationship between bunker price and Baltic Dry-bulk Index (hereafter BDI). Previous investigations employ linear form based analysis between oil price and BDI but we develop nonlinear and asymmetric cointegration method, which is properly able to capture the decreasing and increasing periods differently. The empirical results show there is no relationships in linear model (e.g. Engle and Granger's methods). On the contrary, our estimate reveals there is significant long-run relationship with asymmetric framework, which implies the necessity of nonlinear and asymmetric consideration to the bunker price analysis.

This study analyzed the posture balance of time variation for exercising body a period of time. Posture balance measured output values for the posture balance system of body moving in the multi-parameter. Posture moving variation had three methods such as open and closed eye, head moving and upper body moving. There were checked a parameter that measured vision, vestibular, somatosensory, CNS. This system was evaluated a data through the stability. This system has catched a signal for physical condition of body data such as a data acquisition system, data signal processing and feedback system. The output signal was generated Fourier analysis that using frequency of 0.1Hz, 0.1-0.5Hz, 0.5-1Hz and 1Hz over. The posture balance system will be used to support assessment for body moving the posture balance of time variation. It was expected to monitor a physical parameter for health verification system.
