Baeja(背子), which was excavated from the tomb of Sim, Su-ryun(沈秀崙, 1534-1589), a civil official, has a distinctive pattern. Two rectangles are connected by button knots on both shoulders and below the armpits, and surround the front and back of the upper body. Also, the back is shorter than the front, while the center-front is not opened. It also has a round neckline without a collar. Jeojuji(楮注紙), which is a traditional Korean paper made from mulberry bark, is put between the outer shell and lining of this clothing as an interlining. The purpose of this study is to perform a morphological feature analysis of the Baeja to examine its characteristics and name, and clothes with similar features, attire relic, pictorial and ceramic materials as well as precedent studies were used in the analysis. The Baeja, which was excavated from the tomb of Sim, Su-ryun, has the same pattern as Yangdang(裲檔), which was worn in the ancient northern region and China. Its composition and the way it was worn are very simple. Also, the shorter back length can be used as evidence that it was worn as everyday outer clothing, and not in a ceremony. Jeojuji, used as an interlining, made it easy to sew and maintain attire pattern and played a role of maintaining warmth. Therefore, this Baeja is presumed to be an outer clothing simply worn in the everyday life for convenience and warmth. In regards to its morphological feature, it was most likely a Yangdang in Joseon Dynasty.

In this paper, we propose a complementary metal oxide semiconductor (CMOS) binary image sensor with a gate/body-tied (GBT) PMOSFET-type photodetector for high-speed operation. The GBT photodetector of an active pixel sensor (APS) consists of a floating gate ($n^+$-polysilicon) tied to the body (n-well) of the PMOSFET. The p-n junction photodiode that is used in a conventional APS has a good dynamic range but low photosensitivity. On the other hand, a high-gain GBT photodetector has a high level of photosensitivity but a narrow dynamic range. In addition, the pixel size of the GBT photodetector APS is less than that of the conventional photodiode APS because of its use of a PMOSFET-type photodetector, enabling increased image resolution. A CMOS binary image sensor can be designed with simple circuits, as a complex analog to digital converter (ADC) is not required for binary processing. Because of this feature, the binary image sensor has low power consumption and high speed, with the ability to switch back and forth between a binary mode and an analog mode. The proposed CMOS binary image sensor was simulated and designed using a standard CMOS $0.18{\mu}m$ process.

The bronchoscopy is usually performed in the patients who present symptoms of wheezing, hemoptysis, signs of airway obstruction, unexplained long-term chronic cough with or without radiologic features of pneumonia, emphysema or atelectasis. The symptoms and signs of cases of suspected airway foreign body are of often cofused with those of asthma pneumonia and other respiratory tract disease. The ventilating bronchoscopy will be helpful for removal of certain foreign bodies as well as alleviating medically-unresponsive bronchopulmonary conditions via removing abnormal secretions or merely improving ventilation. The authors have performed clinical analysis of 59 patients who were suspected of airway foreign bodies and treated by ventilating bronchoscopy from September 1985 to February 1995. The results were as follows: 1) Among the 59 cases of bronchoscopy, 51 cases(97%) were under the age of 3. The ratio of male and female was 2.69:1 2) Most common presenting symptom was coughing(84.7%) followed by dyspnea, fever, wheezing and anterior chest pain. 3) Among 39 cases of identified foreign bodies, abnormal findings in the chest X-ray films were found in 33 cases(84.6%) and most common abnormal radiologic feature was pneumonia in 10 cases(25.6%) followed by combination of pneumonia and emphysema, or emphysema alone. All the 20 cases of absent foreign body presented abnormal radiologic features and common findings were pneumonia and atelectasis. 4) Vegetable foreign bodies were the most common form of removed airway foreign bodies(69.2%) followed by metallic foreign bodies(12.8%) and plastic foreign bodies(7.7%). 5) By distribution of the location of foreign bodies, 29 cases(74.4%) were located in the main bronchus( 16 cases of right side and 13 cases of left side), 8 cases were in the trachea and 2 cases were found at the cordal level. 6) By duration of foreign body lodgement in the airway, 9 cases(23.1%) were removed within 7 to 30 days, 10 cases(5.6%) within 3 days and 5 cases(12.8%) were enlodged over 30 days. 7) In the cases of absent foreign bodies, common bronchoscopic findings were mucopurulent or thick mucoid discharge in the main bronchi, erythema or edema of bronchial mucosa and all the cases were improved after ventilating bronchoscopy with concomitant medical management.

Background: Bedridden patients and disabled persons need help from a guardian or caregiver even in performing simple activities of daily living. In particular, for body transfer of them, the use of a transfer lift has been recommended. However, the devices currently in use have limitations in terms of support according to the individual's characteristics. This study aimed to develop a transfer lift device utilizing the patients' body-fitting sling equipped with an air tube inside the sling. In addition, we have conducted usability tests to examine the safety, effectiveness, and satisfaction with this device. Design: This study conducted usability tests with 10 healthy adults. Methods: Customized sling lifts are generally floor-based devices that consisted of a sling that holds the patient's body and a lift that moves the sling to the desired position. One characteristic feature of the device is an air tube, which is used on the sling to allow the patient's body can be adjusted. A usability test was performed in terms of the operators, who operated the device to transfer the patients. Ten operators tried the device and tested its usability. Results: The mean of 10 question for Questions was 4.18. Conclusion: The device can be useful in the advance- ment and commercialization of customized sling lifts, to ensure the safe and efficient transfer of persons with disabilities.

A recent study to determine the fall is focused on analyzing fall motions using a recurrent neural network (RNN), and uses a deep learning approach to get good results for detecting human poses in 2D from a mono color image. In this paper, we investigated the improved detection method to estimate the position of the head and shoulder key points and the acceleration of position change using the skeletal key points information extracted using PoseNet from the image obtained from the 2D RGB low-cost camera, and to increase the accuracy of the fall judgment. In particular, we propose a fall detection method based on the characteristics of post-fall posture in the fall motion analysis method and on the velocity of human body skeleton key points change as well as the ratio change of body bounding box's width and height. The public data set was used to extract human skeletal features and to train deep learning, GRU, and as a result of an experiment to find a feature extraction method that can achieve high classification accuracy, the proposed method showed a 99.8% success rate in detecting falls more effectively than the conventional primitive skeletal data use method.

Vortex shedding which is the dominant feature of body wakes and of direct relevance to practical engineering problems, has been intensively studied for flows past a circular cylinder. In contrast, vortex shedding from a hydrofoil trailing edge has been studied to much less extent despite numerous practical applications. The physics of the problem is still poorly understood. The present study deals with $K{\acute{a}}rm{\acute{a}}n$ vortex shedding from a truncated trailing-edge hydrofoil in relatively high Reynolds number flows. The objectives of this paper are twofold. First, we aim to simulate unsteady turbulent flows past a two dimensional hydrofoil through a hybrid particle-mesh method and penalization method. The vortex-in-cell (VIC) method offers a highly efficient particle-mesh algorithm that combines Lagrangian and Eulerian schemes, and the penalization method enables to enforce body boundary conditions by adding a penalty term to the momentum equation. The second purpose is to investigate shedding frequencies of vortices behind a NACA 0009 hydrofoil operating at a zero angle of attack.
