현대 사회에서 쓰레기 처리는 여러 사회 문제를 일으키고 있다. 넘쳐나는 쓰레기는 미관을 해치고 악취를 발생시킨다. 본 논문은 쓰레기 배출량이 쓰레기통의 수용 용량을 넘는 경우 웹과 앱을 통해 청소 관리자에게 알림을 제공하는 등의 편리한 쓰레기통 관리 시스템을 제안한다. 제공하는 앱과 웹은 데이터베이스와 아두이노 기반의 IoT 기술을 활용하여 쓰레기통 자동 개폐, 쓰레기 압축, 포화 용량 표시 등의 다양한 기능을 제공한다. 앱과 웹을 통하여 수집된 데이터는 추후 환경 관련 프로젝트에서 다방면으로 활용될 수 있다.

This study investigated how consumer's uncertainty avoidance affect purchase deferral intention when purchasing high-involved products (i.e. laptops) in online shopping, and we looked at whether utilitarian/hedonic consumption value has a moderating effect in this relationship. Results showed the higher the uncertainty avoidance, the higher the deferral intention. Also, only the utilitarian consumption value had moderating effect in this relationship. This means that in an information overload situation like online shopping, consumers are more likely to delay their purchase intention when they have more uncertainty avoidance. Thus, to prevent this purchase delay, marketers should selectively present relative product information, strategically emphasize the importance of certain product attribution to reduce consumers' uncertainty of the product or highlight the utilitarian values of product attributes that are expected to have a significant impact on decision making.

Purpose: This study analyzed the muscle activity changes induced by motions of reaching forward and chest expansion that were examined from the bilateral muscles with rectus abdominis, external oblique, multifidus, and longissimus thoracic using Pilates cadillac instrument. Methods: Nine young adult women, who have no musculoskeletal disorder and any of chronic diseases, were participated. Surface electromyography system was used for recording of all signals produced by muscles, and then normalized as percentage of maximum voluntary isometric contraction (%MVIC). The paired t-test and repeated measures of analysis of variance was performed. Results: Reaching-forward motion showed a higher muscle activity from non-dominant external oblique muscle than that of the chest-expansion motion. During both reaching-forward motion and chest-expansion motion, MVIC values collected from dominant side of external oblique muscle were shown a significantly lower than the values obtained from non-dominant side (p<0.05). Conversely, %MVIC values in external oblique muscle collected from dominant side showed a significantly higher than the values obtained from non-dominant side of the same oblique muscle (p<0.05). Reaching-forward motion was caused a higher %MVIC on non-dominant external oblique muscle than that of the chest-expansion motion (p<0.05). Regardless of dominant or non-dominant sides, external oblique muscle was shown the highest activation rate of all the other muscles during reaching forward action, and longissimus thoracic muscle was shown the highest activation rate of all the other muscles during chest expansion action. Conclusion: Reaching-forward motion is suitable for activating an external oblique muscle, and chest-expansion motion is an effective enough in activating of longissimus thoracic muscle.

Today, the handicapped or old people require continuous care, but there are a lot of practical difficulties. In this paper, the system measuring health conditions of the handicapped or old people (pulse and temperature) is developed. If urgent health conditions occur, measurement values are delivered to doctors or close family members using SMS (Short Message Service) of cellular phone. In the developed system, Pulse rate is measured by sensing bloodstream using high luminance LED and CdS illumination sensors. Body temperature is also measured by contactless temperature sensor. Also, the measured values are transmitted to a server computer using Zigbee communications. Also, the measured values the average of measurements and the time are saved. The wireless healthcare system is designed to help the emergency for the handicapped and old people by using SMS.

Objectives: The study investigated the effect of Korean medicine treatment on a hemiplegic patient with conscious and cognitive disorders due to hemorrhagic transformation after interventional reperfusion therapy of anterior circulation infarction. Case presentation: The patient was treated with acupuncture, moxibustion, cupping, and herbal medicine in combination with Western medicine and physical therapy. The effects on clinical symptoms were evaluated using the Manual Muscle Test (MMT), Glasgow Coma Scale (GCS), Korean Mini-Mental State Examination (K-MMSE), Korean Nursing Delirium Screening Scale (Korean Nu-DESC), and Modified Bathel Index (MBI). After the treatment, the MMT grade increased from Gr.0-1 to Gr.0-3, the GCS score increased from 10 to 15, the K-MMSE score increased from 8 to 15, the Korean Nu-DESC score decreased from 3 to 1, night delirium disappeared, and the MBI score increased from 13 to 26. Conclusions: Complex Korean medicine treatments were effective for improving the clinical symptoms of hemorrhagic transformation after interventional reperfusion therapy for anterior circulation infarction in a patient with hemiplegia and conscious and cognitive disorders. However, further studies are needed.

The biggest type of behavior that prevents people with developmental disabilities from entering society is aggressive behavior. Aggressive behavior can pose a threat not only to the personal safety of the person with a developmental disability, but also to the physical safety of others. In this study, we propose a wearable system using a low-power processor. The proposed system uses an IMU (Inertial Measurement Unit) to analyze user behavior, and when attack behavior is not detected for a certain period of time through an LED array attached to the developed system, an interesting LED is displayed. By expressing patterns, we provide behavioral intervention through compensation to people with developmental disabilities. In order to implement a system that must be worn for a long time in a power-limited environment, we present a method to optimize performance and energy consumption across all stages, from data preprocessing to AI model application.
