  • Objectives : Southern, northern, and wild types of Osterici Radix, and Notopterigii Rhizoma et Radix imported from China are circulated in Korea. Morphological identification was attempted by comparing powder forms of these materials. Methods : To make the specimen, the samples were grinded, and the powder was mounted by a solution of Glycerin, Acetic acid and Water at the rate of 1 : 1 : 1. The specimen was mounted by optic microscope, photographs were taken and the characteristics were sketched in lines. Result : 1. Korean Osterici Radix was yellow-brown, but Chinese Notopterigii Rhizoma et Radix was dark-brown. 2. Oil ducts were mostly broken, and most of secretory cells were narrow and long, including yellow or light yellow secretion and starch grain. 3. Parenchyma cells were rectangular, and southern type of Osterici Radix and Chinese Notopterigii Rhizoma et Radix include lots of starch grain in parenchyma cells, while northern type of Osterici Radix and wild Osterici Radix include a little. 4. Vessels were usually reticulate vessel, and the diameter of the vessels of Korean Osterici Radix was $25{\sim}88{\mu}m$, while that of the vessels of Chinese Notopterigii Rhizoma et Radix was $13{\sim}52{\mu}m$. 5. The surface of accessory cells were light brown with the shape of irregular polygon. Conclusion : Southern type of Osterici Radix, nothern type of Osterici Radix, wild Osterici Radix, and Chinese Notopterigii Rhizoma et Radix were all alike, except the amount of starch grain in parenchyma cells.

  • Recently, as interest in health increases, various wearable devices such as smart watch and smart band which can measure user's biometric information are being studied. Conventional wearable devices service the measured biometric information in a form that provides simple monitoring, disease prevention, and exercise amount. However, the user is Lack to deal with the dangerous situation. In this paper, we propose a hazard notification system to address these problems. The biometric information measured by the acceleration sensor and the heart rate sensor is transmitted to the application through the Arduino in real time. It identifies the risk situation through sensor priority measurement and risk situation identification algorithm. If a dangerous situation occurs, a notification message is sent to the guardian indicating the current location of the user. Therefore, it can be expected that if a dangerous situation occurs to a user who needs protection, he can respond promptly.

  • Purpose: This study aimed to provide basic data to enhance self-nursing ability by investigating the symptoms of autonomic neuropathy and self-management activities in patients with diabetes accompanying hypertension. Methods: Subjects were 113 type-2 diabetic patients who were diagnosed as hypertensive in two primary medical institutions and taking anti-hypertensive treatments. The existence of postural hypotension was evaluated by blood pressure and pulse rate, and the subjective symptoms of autonomic neuropathy and self-management activities were checked by structured questionnaires. The collected data were analyzed by chi-square test, Fisher's exact test, t-test, Wilcoxon rank sum test and analysis of covariance. Results: Postural hypotension occurred in 4.4% of the subjects. Urinary frequency and dizziness during postural changes were the most frequent symptoms of autonomic neuropathy, and 57.5% of the subjects complained of symptoms in two or more domains. The group with autonomic neuropathy symptoms showed higher age, higher living stress, and fewer self-management activities in the diet and foot management domains as compared to the group without autonomic neuropathy symptoms. Conclusion: From these results, we learned that strengthening education on self-management for diet and foot management and customized interventions considering age and living stress are required through early identification of the symptoms of autonomic neuropathy in patients with diabetes accompanying hypertension.

  • In this paper, the characteristics of MODEM with the low and medium transmission rate which are recommended by the international organization such as CCITT have been studied and the features of the telephone channel have been investigated. Then three kinds of classification algorithm for the modulated signals have been suggested and their performance have been researched through the computer simulation. In case that the channel is ideal, the modulated type such as FSK, PSK and QAM could be detected correctly. Moreover, when the modulated signals are received through the telpehone channel or noisy channel, it could be seen that the performance of the correlation algorithm is superior to that of other two algorithms because of the correlation being robust to the characteristics of telephone chanel and Gasussian noise, although the performances of the two classification algorithm using the peak and phase difference, signal constellation and so on decrease rapidly as the amplitude distortion, delay distortion and Gaussian noise increase.

  • Biometric systems are forms of technology that use unique human physical characteristics to automatically identify a person. They have sensors to pick up some physical characteristics, convert them into digital patterns, and compare them with patterns stored for individual identification. However, lip-print recognition has been less developed than recognition of other human physical attributes such as the fingerprint, voice patterns, retinal at blood vessel patterns, or the face. The lip print recognition by a CCD camera has the merit of being linked with other recognition systems such as the retinal/iris eye and the face. A new method using multi-resolution architecture is proposed to recognize a lip print from the pattern kernels. A set of pattern kernels is a function of some local lip print masks. This function converts the information from a lip print into digital data. Recognition in the multi-resolution system is more reliable than recognition in the single-resolution system. The multi-resolution architecture allows us to reduce the false recognition rate from 15% to 4.7%. This paper shows that a lip print is sufficiently used by the measurements of biometric systems.

  • According to the recent systemic changes such as construction market reduction, five days per week system, introduction of construction duration reduction bidding system and post-construction sale system, the bidding competition have been enhanced. However, there are many construction schedule risks which could delay construction completion. Without the proper identification of construction schedule risks and the structured construction schedule risk management, the competitive advantages of construction project could not be made. Previous researches to solve the problem have been focused on the construction schedule categorization, construction schedule management, and the system development to manage the construction schedule risk. Therefore, this study selected the reinforeced concrete construction as the studied work due to the major impact characteristics on the total construction duration and the quite accident rate, and then proposed the real construction schedule risks of reinforced concrete construction and the construction risk management method based on the previous studies, many times of expert interviews and brainstorming.

  • Super resolution image reconstruction method refers to image processing algorithms that produce a high resolution(HR) image from observed several low resolution(LR) images of the same scene. This method has proven to be useful in many practical cases where multiple frames of the same scene can be obtained, such as satellite imaging, video surveillance, video enhancement and restoration, digital mosaicking, and medical imaging. In this paper, we applied the super resolution reconstruction method in spatial domain to video sequences. Test images are adjacently sampled images from continuous video sequences and are overlapped at high rate. We constructed the observation model between the HR images and LR images applied with the Maximum A Posteriori(MAP) reconstruction method which is one of the major methods in the super resolution grid construction. Based on the MAP method, we reconstructed high resolution images from low resolution images and compared the results with those from other known interpolation methods.

  • This nationwide survey was conducted to evaluate the current status of the database system on gastric cancer patients in Korea. The Information Committee of Korean Gastric Cancer Association (KGCA) sent questionnaires about the database management to all 402 KGCA members in 110 institutes. In addition, we asked them to send the gastric cancer sheet and the pathologic report of gastric cancer used in their institutes. Response rates were $18.9\%$ (76/402) for individuals and $51.8\%$ (57/110) for institutes, respectively. Most of the university hospitals responded to the questionnaire (response rate of university hospital: $74.6\%$, 44/59). A regular conference of gastric cancer and a digitalization of the database on gastric cancer patients were performed in 29 ($50.9\%$) and 43 ($75.4\%$) out of 57 institutes, respectively. MS excel was most commonly used for the digitalization of the database, followed by MS access and SPSS. A regularly formed gastric cancer sheet and pathologic report were used in 38 ($66.7\%$) and 49 ($86.0\%$) institutes, respectively. Hospital computerization, such as an Order Communicating System, an Electric Medical Record, and a Picture Archiving/Communicating System had been set up previously or would be set up in the near future in most institutes. In 25 gastric cancer sheets collected, the mean number of total items was 72.9 ($15\∼177$). Identification datafor the patients, surgical data, and pathologic data were included on most of the sheets, but preoperative status, preoperative diagnostic data, and postoperative hospital course were not.

  • Objectives The high suicide rate has risen as a main concern in South Korea. Given the complexity of the mechanism resulting in complete suicide, studies targeting various populations are needed for broader understanding of its risk factors. This study aims to analyze the factors affecting the suicidal tendency in the population of the elderly living alone in Seoul depending on basic elderly-care services. Methods A total number of 415 people participated in the study. Home-visit interviews were administered by trained interviewers. Suicidal tendency was measured by the Korean version of mini international neuropsychiatric interview (K-MINI). Health-related quality of life was measured by a brief version of the World Health Organization Quality-of-life Scale (WHOQOL-BREF). Alcohol problem was assessed by the Korean version of the alcohol use disorders identification test (AUDIT-K). Among total subjects of 415 interviewees, the actual responses of 408 people were used for the final analysis. Results The result showed that the suicide risk was high in persons isolated from social support [odds ratio (OR) = 4.49], having depression (OR = 14.85), and having low quality of life (OR = 4.39). Conclusions We found that social support, depression and health-related quality of life are associated with suicidal tendency in the elderly living alone on basic services. Our evidence will contribute to suicide prevention policy for the elderly living alone on care services.
