PURPOSE: The aim of this study was to investigate the effect of scapular dynamic taping on pain, disability, upper body posture, and range of motion (ROM) in the postoperative shoulder. METHODS: Twenty-two patients who underwent acromioplasty and rotator cuff repair surgery volunteered for this study. The subjects were randomly divided into an experimental group (EG, n=11) and a control group (CG, n=11). For the EG, exercise therapy, manual therapy, and scapular dynamic taping were applied for 6 weeks; for the CG, only exercise therapy and manual therapy were applied for 6 weeks. Shoulder pain, disability, upper body posture, and ROM were evaluated at baseline, after 3 weeks of intervention, and after 6 weeks of intervention. Assessment tools included quadruple visual analog scale (QVAS) for level of pain; shoulder pain and disability index (SPADI) for functional disability level; forward head angle (FHA), forward shoulder angle (FSA), and pectoralis minor index (PMI) for upper body posture; and ROM testing. RESULTS: Significant differences were observed between the EG and CG in SPADI total scores; internal rotation and external rotation ROM of the glenohumeral joint ; FSA ; and PMI. All groups showed statistically significant improvement in QVAS; SPADI; flexion; abduction; external rotation and internal rotation ROM of the glenohumeral joint; FSA; and PMI. CONCLUSION: These results suggest that, for patients who have undergone acromioplasty and rotator cuff repair surgery, the addition of scapular dynamic taping during therapy is effective for improvement of shoulder disability level, ROM, and upper body posture.

Purpose: This study aimed to investigate changes in upper extremity joints and leisure satisfaction in children with brain lesions through sports stacking activities. Methods: A sports stacking program was conducted on three children with brain lesions who had upper extremity joint limitations and joint range of motion lower than the normal range. It was conducted 10 times, 1 to 2 times a week, 40 minutes each time. Upper extremity joint angles were measured using a goniometer in the order of shoulder, elbow, wrist, and fingers, and leisure satisfaction was measured using a smile evaluation. Results: As a result of measuring the upper extremity joint angles, all three children showed slight angle changes in the shoulder, elbow, and wrist areas. Differences in joint angles appeared differently for each child. Smile evaluation results were evaluated in various psychological, educational, and physical aspects. Only child A was evaluated for Smile Evaluation No. 1. Conclusion: Sports stacking activities changed the upper extremity function of children with brain lesion disorders and showed differences in psychological, physical, and educational aspects of leisure satisfaction. As this is a short-term study result, the change in upper extremity function is minimal, but if sports stacking activities are continued, it will be a rehabilitation program that can prevent upper extremity dysfunction and improve physical strength. Accordingly, continuous attention should be paid to increasing accessibility and enjoyment of daily life according to individual characteristics and level.

The impact of midlatitude synoptic system (upper-level trough) on typhoon intensity change was investigated by analyzing the spatial and temporal characteristics of vertical wind shear (VWS), relative eddy momentum flux convergence (REFC), and potential vorticity (PV). These variables were computed over the radial mean $300{\sim}1,000km$ from the typhoon center by using GDAPS (Global Data Assimilation and Prediction System) data provided by the Korea Meteorological Administration (KMA). The selected cases in this study are typhoons Rusa (0215) and Maemi (0314), causing much damage in life and property in Korea. Results show that the threshold value of VWS indicating typhoon intensity change (typhoon to severe tropical storm) is approximately 15 m/s and of REFC ranges 6 to 6.5 $ms^{-1}day^{-1}$ in both cases, respectively. During the period with the intensity of typhoon class, PVs with 3 to 3.5 PVU are present in 360K surface-PV field in the cases. In addition, there is a time-lag of 24 hours between central pressure of typhoon and minimum value of VWS, meaning that the midlatitude upper-level trough interacts with the edge of typhoon with a horizontal distance less than 2,000 km between trough and typhoon. That is, strong midlatitude upper-level divergence above the edge of the typhoon provides a good condition for strengthening the vertical circulation associated with the typhoons. In particular, when the distance between typhoon and midlatitude upper-level trough is less than 1,000 km, the typhoons tend to weaken to STS (Severe Tropical Storm). It might be mentioned that midlatitude synoptic system affects the intensity change of typhoons Rusa (0215) and Maemi (0314) while they moves northward. Thus, these variables are useful for diagnosing the intensity change of typhoon approaching to the Korean peninsula.

Korean mid- and upper-level aviation turbulence guidance (KTG) system is developed using the unified model (UM)-based regional data assimilation and prediction system (RDAPS) of the Korea Meteorological Administration. The KTG system includes three steps. First, the KTG system calculates a suite of diagnostics in the UM-RDAPS domain. Second, component diagnostics that have different units and numerical magnitudes are normalized into the values between 0 and 1, according to their own thresholds in the KTG system. Finally, normalized diagnostics are combined into one KTG predictor by measuring the weighting scores based on the probability of detection, which is calculated using the observed pilot reports (PIREPs) exclusively of moderate-or-greater (MOG) and null (NIL) intensities. To investigate the optimal performance of the KTG system, two types (RD-KTG and UM-KTG) of the KTG systems are developed and evaluated using the PIREPs over Korea and East Asia. Component diagnostics and their thresholds in the RD-KTG are founded on the 8-yrs (2002.12-2010.11) MM5-based RDAPS (previous version of the RDAPS; ${\Delta}x$ = 30 km) and PIREPs data, while those in the UM-KTG are based on the 6 months (2010.12-2011.5) UM-based RDAPS (${\Delta}x$ = 12 km) and PIREPs data. In comparison between the RD-KTG and UM-KTG, overall performance of the UM-KTG (0.815) is better than that of the RD-KTG (0.79) during the recent 6 months, because forecasting skill for the upper-level wind is higher in the UM-RDAPS than in the MM5-RDAPS. It is also found that the UM-KTG is more efficient than the RD-KTG according to the statistical evaluations and sensitivity tests to the number of component diagnostics.

Background: The purpose of this study is to investigate changes in physical and cognitive function according to the level of independence in performing activities of daily living in stroke patients. Design: Retrospective study. Method: This study is a retrospective study analyzing medical records. This study utilized data collected from 123 stroke patients at admission in a local rehabilitation hospital between 2019 and 2022. Stroke patients were classified into 5 groups based on the scores of the Korean Modified Barthel index (K-MBI) evaluated at the time of hospitalization at a rehabilitation hospital, and investigated the change in physical (spasticity (modified Ashworth scale), muscle strength (manual muscle test), gait ability (functional ambulation category), upper extremity function (manual function test), and balance function (berg balance scale)) and cognitive function (Korean mini mental status examination) according to the level of independence in performing activities of daily living. Result:: As a results, significant differences were observed in the physical (muscle strength, gait ability, upper extremity and balance functions) and cognitive functions of stroke patients according to the level of independence in performing activities of daily living (p<0.05). However, there was no significant difference in upper and lower extremities spasticity. Conclusions: Through the results of this study, we found that the physical (muscle strength, gait ability, upper extremity and balance functions) and cognitive function were influenced by the level of independence in performing activities of daily living in stroke patients.

Generally, the accuracy of the prediction of flood elevation is difficult to identify due to the sedimentation on a river bed, earth and sand being moved by flow, and localized torrential downpours caused by climate change. It is also because of natural and artificial influences on rivers. To predict river floodings successfully, more precise and reliable flood elevation prediction system is needed, in which the concentration time of downstream is numerically interpreted through analyzing and utilizing the watermark of the upper region. Therefore, this research analyzed the prediction methods of the changes in water levels, which use the watermarks of the upper region. The watermarks which impacts the spot being predicted of flood was selected through floodgate analysis and correlation analysis. With the selected watermarks, a statistically reliable regression equation was yielded.

Total capacity of pumped hydro storage(PHS) in Korean power system reaches 4,700MW, though the share of it is about 4.56% of total capacity The Unit Commitment program, E-terracommit which is used for the operational purpose by KPX, includes the PHS model. But the model has a defect that it does not include the information of water level of upper reservoir. Therefore two types of improved the PHS models are represented in this paper. The first model is a optimized model by connecting the upper reservoir water level to the non-spinning reserve. The other model is to have priority allocate both the PHS and combined cycle generator for non-spinning reserve. The proposed two models and the E-terracommit model is compared and resulting to have improvement in estimating non-spinning reserve when using the proposed models.

The purpose of this study was to investigate how much students stress have, how they cope with this stress, differences between problem behaviors and personality changes based on stress, and stress differing levels when coping with the situation either actively or passively The hypotheses were stated as follows. 1. There will be differences between problem behaviors and personality problems based on sex. 2 There will be differences between problem behaviors and personality problems based on grade. 3. There will be differences between problem behaviors and personality problems based on stress level. 4. There will be differences between problem behaviors and personality problems based on a student's ability to cope with stress. 5. Upper level students under lower stress and lower level students under higher stress will have more problems behaviors and more personality problems. 300 male/female high school students throughout the Seoul area were randomly selected. Of the 300 subjects that were sampled, 294 (Male=145, Female=149) actually participated in this study. The Stress Scale developed by Lazarus & Folkman (1984) Problem Behavior Scale, Personality Problem Scale, and Checklist were used and the conclusions are stated as follows. First, male students have more anti-social behavior and higher anti-social tendencies than female students and female students have more self-depreciation than male students. Second, upper level students have more anti-social behavior, self-ego, fabrication, and higher personality problems than lower level students. Third, students having too much stress have more anti-social behavior, self-ego, and fabrication and personality problems than students having less stress. Fourth, students coping with stress actively showed less self-ego and fabrication and less thought disturbance, anti-social tendencies, and self-depreciation than students coping with stress passively. Finally, upper level students under lower stress and lower level students under higher stress have more fabrication behaviors and more thought disturbance and self-depreciation.

Recently, there has been enormous damage due to river floodings caused by localized heavy rains. The direct discharge triggered by those torrential rains inflicts severe property damage on the residents of nearby areas. To minimize the possibility of river floodings in case of heavy rains and to predict the possible damage, the management of existing rainfall and water level observatories should be checked and prediction methods based on the characteristics of water usage and floodgate of nearby rivers must be further analyzed. Therefore, this research analyzed the water level change predictions on different spots with a regression equation of rainfall and water levels, using the observation data of the water level observatory in Jeongseon-gun, Gangwon Province and the rainfall observatory which are located on the upper region of the Han river.
