The purpose of this study was to investigate the differences of lumbar muscle activity (LMA) and oxygen consumption (OC) according to bike saddle height in healthy young men. Twenty-two subjects without musculoskeletal disorders participated in this study. Subjects performed 3 min cycling at 3 different saddle heights with 10 minutes of resting time respectively. Surface EMG was used to assess muscle activity in LMA, and OC was assessed by potable gas analyzer. In the result, there was a statistically significant difference in internal oblique abdominis activity (p<0.05), and the OC was significantly higher in high saddle height than the optimal and the low position of the saddle (p<0.05). This study suggest that changes in saddle height affected internal oblique abdominis activity and OC in subjects, however, saddle height does not have much effect on lumbar stabilizer muscle.

In this study, 200 social workers in Seoul and Gyeonggi area were surveyed using convenience extraction method. Data were analyzed by frequency, reliability, correlation, and regression analysis using IBM SPSS Statistics 20, and Sobel test was performed. The purpose of this study was to investigate the effects of empowerment on the relationship between exhaustion and organizational effectiveness of social workers and to provide basic data for improving organizational effectiveness. The results of the study are as follows. Empowerment was found to be mediated in the relationship between exhaustion and job satisfaction, which is a sub - area of organizational effectiveness. Empowerment was found to be mediated in the relationship between exhaustion and turnover intention, which is a sub - domain of organizational effectiveness. Therefore, it is necessary to have a resting place that gives a sense of security to the exhausted social worker rather than granting authority for the social welfare organization.

The urban river has played an important role in biodiversity by providing various waterside areas in urban areas that are difficult for organisms to live in. The river is also used as a resting place and experience space for citizens. In particular, Yeouido Saetgang is the first ecological park in Korea, and it is located in the heart of downtown Seoul, making it highly valuable for its location and ecological value. However, water quality issues have continuously been raised since the construction project of Yeouido Saetgang river. So it is necessary to investigate the environment state and analyze the causes of the environment deterioration. In this study, the causes of the river stagnation and water quality deterioration in Yeouido Saetgang river were analyzed. For this, river surveys and aerial photo analysis were used to analyze the causes of difficulties in natural water circulation. Also, the results of monitoring water quality showed that the averaged level of BOD and T-P in dry season is III and IV, respectively, while that of BOD and T-P are V~VI in rainy season. In addition, through the drainage analysis of sewer network, small drainages that affect the water quality in Saetgang river was selected and discussed.

Long-term use of digital screens in daily life can lead to computer vision syndrome including symptoms such as eye strain, dry eyes, and headaches. To prevent computer vision syndrome, it is important to limit screen usage time and take frequent breaks. There are a variety of applications that can help users know the screen usage time. However, these apps are limited because users see various screens such as desktops, laptops, and tablets as well as smartphone screens. In this paper, we propose and evaluate machine learning-based models that detect the screen device in use using color, IMU and lidar sensor data. Our evaluation shows that neural network-based models show relatively high F1 scores compared to traditional machine learning models. Among neural network-based models, the MLP and CNN-based models have higher scores than the LSTM-based model. The RF model shows the best result among the traditional machine learning models, followed by the SVM model.
