This study investigates the exercise-physiological changes in stages through the movement of the automatic stepper and to analyze the usefulness of the automatic stepper. For 18 male university students, out of 10 levels, 5 level and 10 level of automatic stepper exercise were performed. At each 10, 20, 30 minutes during exercise, 5 and 10 minutes after exercise stop the subjects were examined to analyze the changes in energy consumption after minutes, respiratory exchange rate, heart rate, oxygen consumption per body weight, METs, cumulative energy consumption, and lactic acid to verify the usefulness of the automatic stepper. The mean and standard deviation were calculated using the SPSS, and one-way ANOVA with repeated measure was performed to verify the difference in the mean between time periods. The LSD method was used for the post-hoc test, and the significance level was set to α = .05. There were no significant changes in both 5 and 10 level, but the cumulative energy consumption over time increased significantly. In addition, as a low-intensity exercise intensity is shown, a low increase in lactic acid indicated a safe exercise level. In future studies, in-depth studies of various variables through regular exercise programs are needed for those who need safe exercise.

The aim of this study is to design and develop the gait rehabilitation equipment that judge patient's movement of his/her center of gravity using pressure sensors, and to aid hemiplegic patients to balance themselves using an automatic stepper that changes the patient's center of gravity. It is hard to bear the weight on the affected side for hemiplegic patients. The gait rehabilitation equipment detects the footing phase of hemiplegic patient during training and moves the unaffected footing side of the stepper up and moves the affected footing side down simultaneously so that the patient's center of gravity can shift from unaffected side to affected side. The gait rehabilitation system was developed and applied for hemiplegic patients during exercise. Eight hemiplegic patients and one normal adult were studied. The developed gait rehabilitation system could judge not only the normal adult's intention but also the patient's intention to move his/her center of gravity. Even though the most of hemiplegic patients exercised in automatic mode and a few hemiplegic patients exercised in manual mode, the developed gait rehabilitation system can aid the hemiplegic patients to train more easily.

본 논문에서는 현재 주사바늘을 이용하여 종자를 흡입하고 트레이 상부에서 배기하여 트레이의 셀에 종자를 파종하고 있는 방식의 자동 파종 시스템에 대하여, 작업 능률을 향상시키기 위하여 진공상태의 드럼에 종자를 흡입시켜 회전하면서 트레이에 종자를 배출하게 되는 고속의 시스템을 구현하였다. 트레이를 이송시켜주는 컨베이어 벨트는 상부의 부하의 변화 또는 장치의 마모 등 시간이 지남에 따라 속도가 변할 수 있으므로 속도에 맞추어 드럼의 회전 속도를 자동으로 제어하기 위한 알고리즘을 구현하고 구현된 알고리즘에 따라 드럼을 회전시키기 위한 스테핑 모터의 펄스를 제어하는 회로를 구성하여 시스템을 설계하였다.

요즘 홈 의료 관련 서비스와 건강컨설팅과 같은'헬스 케어'에 대한 관심이 급증하고 있다. 우리 주변에서 스마트 와치, 스마트 러닝머신, 실내 운동게임 등의 헬스 케어 제품을 쉽게 찾아 볼 수 있다. 헬스케어를 위해 가장 쉽고 보편화 된 방법 중에 하나가 매일 비타민 등의 영양제를 챙겨 먹는 것이다. 비타민 등의 영양제 복용 및 보관이 더욱 간편하고, 주기적으로 꾸준히 섭취할 수 있도록 약을 자동으로 배급하는'자동 알약 배급기'를 구현하였다.'자동 알약 배급기'는 사용자가 지정해 놓은 시각에 알람이 울리고, 초음파센서를 통해 사용자의 손이 인식 되면 모터가 작동하여 알약이 배급되게 된다.'자동 알약 배급기'는 약의 남용과 방지하고, 약의 오염도 최소화 할 수 있을 것으로 기대된다. 더 나아가 '자동 알약 배급기'를 더 활용하면 병원 등에서 많은 인원을 더 효율적으로 관리 할 수 있을 것이다. 또, 어떤 약을 얼마만큼 배급되었는지 자동으로 기록되어 진다면 더 효과적이고 더 건강하게 약을 섭취 할 수 있을 것이다.

Purpose-Meat plays an important role in the Chinese daily diet, however, due to the spread of COVID-19, food supply and safety have become a major concern. The safety and health features of chilled fresh meat have attracted the attention of consumers. To study consumers' purchasing behavior and willingness to pay for chilled meat under the influence of the epidemic. Research methodology- The data were obtained by questionnaire survey, major issues include consumers' meat consumption habits in the wake of the COVID-19 and their awareness of meat product quality labels. In addition, the gender, age, family income, and other basic personal information of the interviewees were also counted. Based on the binary Logit regression method, we study consumers' purchasing behavior and willingness to pay for chilled meat under different demographic characteristics. Results-The results showed that brand and quality certification are important factors influencing purchases. In addition, the presence of children under the age of 12 in the household and the level of income and education also influence consumers' purchase intention of the chilled fresh meat. However, mart promotions and city ratings can significantly lower consumers' propensity to buy the chilled fresh meat. Apart from this, such factors as gender, age, and living conditions have no significant influence on consumers' purchase of chilled fresh meat.
