현재, Covid-19의 밀접접촉자를 찾아내어 진단검사를 통해 Covid-19 확산을 차단하고 있다. 하지만 확진자의 잠복 기간이 2주가 되고, 확진자의 동선을 추적하여 접촉자를 찾기에 많은 인력과 시간, 비용이 소요된다. 특히, 확진자의 수가 증가할수록 접촉자를 찾아 사전에 차단하는 비용이 기하급수적으로 증가하여 한계점을 가진다. 접촉자를 찾기 위해 전 국민이 상점이나 식당 등 편의시설을 방문할 때마다 전자출입명부를 기록해야 하는데 이는 개인의 위치 정보에 대한 프라이버시 침해 가능성이 높다. 본 연구에서는 자신의 위치와 시간을 실시간으로 저장하고, KDCA에서 수집된 감염자의 동선 정보를 다운받아 겹치는 지점이 있을 경우에 사용자에게 통지하여 사전에 진단검사를 유도하는 시스템을 설계하고자 한다. 제안 기법은 상점을 방문할 때 전자출입명부를 기록해야 하는 번거로움을 해결하면서 개인정보를 사전에 KDCA에 제공하지 않아 프라이버시 침해를 차단할 수 있다.

Purpose: This study aimed to describe a school health teacher's experience working in a mountain village during the COVID-19 outbreak in 2021. Methods: The study used a case study method based on the school records and reports to the local office of education. Results: In T City, since the first COVID-19 case confirmed on March 8, 2020, as of May 17, 21, a total of 21 cases have occurred, including two third-year students of H Middle School. Since then, one additional case was confirmed on May 18, one more on May 25, and one more on May 27, resulting in a total of five confirmed cases. During this period, 42 students and 13 teachers were self-quarantined, all students and staff were tested for COVID-19 PCR, and students received remote classes. The role of school health teacher can be described through three categories: "collaborator", "care coordinator", and "educator". The school health teacher did a lot of work until the situation came to an end, successfully fulfilling these three roles. Conclusion: Some suggestions were made to prepare a more effective communicable disease response system suitable for public health infrastructure of non-urban area.

Eleven patients with esophageal diverticulum were operated on between August 1982 and August 1992 at the Department of Thoracic and Cardiovascular Surgery of Chonnam National University Hospital have been studied. 9 patients were male and 2 were famale and the age distribution was between 20 and 55 years. Various subjective symptoms were noticed preoperatively. Diagnosis was confirmed by esophagography. The types of esophageal diverticulum were traction type in 6 cases and pulsion type in 5 cases. There were nine cases of midesophageal diverticula, 1 cases of upper-thoracic esophageal diverticulum and 1 cases of epiphrenic diverticulum. Diverticulectomy alone in 10 cases and diverticulopexy was performed in 1 case. Fistulectomy in 5 cases, lobectomy in 1 case, segmentectomy in 1 case, and Eloesser`s procedure in 1 case were performed with associated procedures. There were no death or morbidity and all patients have achieved marked improvement of symptoms except three patients who had a concomitant mucoepidermoid tumor, had a complicated postoperative pyothorax, and had a postoperative recurrence of midesophageal diverticulum. Recurrence of symptoms were not noticed during follow up except 1 recurrence of diverticulum confirmed by esophagogram.

The objective of this study was to reverse engineer a swash plate type piston pump mounted on a wheeled armored vehicle and to analyze the structure of the pump case. From the analysis, the weak parts were identified and corrected in the final design. Each element corresponding to the piston pump case was analyzed. The analytical method was given static boundary conditions, load conditions and confirmed displacement, strain, stress, and safety factor. Plastic deformation and damage were also confirmed and the component elements redesigned through structural analysis Structural analysis and vibration analysis were carried out for the components of the piston pump case. The piston pump model was finally modified by structural analysis and vibration analysis results for each component assembly, and a prototype was designed. Durability test and environmental test were carried out and the test results satisfied all of the requirements. Therefore, the analytical method presented in this study can be utilized as a methodology for element component design in the development of various piston pumps.

Objectives: Korea and Japan have managed the spread of coronavirus disease 2019 (COVID-19) using markedly different policies, referred to as the "3T" and "3C" strategies, respectively. This study examined these differences to assess the roles of active testing and contact tracing as non-pharmaceutical interventions (NPIs). We compared the proportion of unlinked cases (UCs) and test positivity rate (TPR) as indicators of tracing and testing capacities. Methods: We outlined the evolution of NPI policies and investigated temporal trends in their correlations with UCs, confirmed cases, and TPR prior to the Omicron peak. Spearman correlation coefficients were reported between the proportion of UCs, confirmed cases, and TPR. The Fisher r-to-z transformation was employed to examine the significance of differences between correlation coefficients. Results: The proportion of UCs was significantly correlated with confirmed cases (r=0.995, p<0.001) and TPR (r=0.659, p<0.001) in Korea and with confirmed cases (r=0.437, p<0.001) and TPR (r=0.429, p<0.001) in Japan. The Fisher r-to-z test revealed significant differences in correlation coefficients between the proportion of UCs and confirmed cases (z=16.07, p<0.001) and between the proportion of UCs and TPR (z=2.12, p=0.034) in Korea and Japan. Conclusions: Higher UCs were associated with increases in confirmed cases and TPR, indicating the importance of combining testing and contact tracing in controlling COVID-19. The implementation of stricter policies led to stronger correlations between these indicators. The proportion of UCs and TPR effectively indicated the effectiveness of NPIs. If the proportion of UCs shows an upward trend, more testing and contact tracing may be required.

The present paper attempts to investigate the factors which may affect the attitude toward Oriental Medicine among the university students in Korea and China. The research on determining factors that may influence the attitude toward the Oriental Medicine can provide the answers for the question how the traditional things can acquire their present position and make a development in modern society. The East Asian countries such as Korea and China have promoted the western-style changes and development, thinking that modernization means the westernization. Given this, the research on the attitude toward Oriental Medicine can be a good case study that shows how tradition sustains its place and develops. The present study makes two hypotheses in order to analyze the factors which make the influence on the attitude toward the Oriental Medicine: Hypothesis there will be no significant difference between the socio-demographic variables and attitude toward Oriental Medicine. Hypothesis there will be significant differences between traditionalism, modernity, nationalism, and attitude toward Oriental Medicine. The statistical results show that hypothesis 1 was confirmed in the case of the gender of the participants, whereas it was not confirmed in the case of the birthplace, economic status, and nationality. And hypothesis 2 was not confirmed in the relations between nationalism and modernity and the attitude toward Oriental Medicine, whereas it was confirmed in the relations between traditionalism and the traditional medical concept and attitude toward Oriental Medicine.

Pleural mesothelioma which arise from pleura is relatively uncommon tumor. We are reporting 2 cases of pleural mesothelioma which were treated with surgical resection. First case, benign epithelial mesothelioma was confirmed incidentally after decortication due to localized pleural thickening. The second case, malignant mesothelial mesothelioma was diagnosed by examination of chest radiology, diagnostic pneumogram and pleural biopsy as malignancy which was treated with the resection of the tumor mass. In the first case, postoperative recurrence of tumor growth was found within 1.5 months after resection. In the section malignant case, no evidence of recurrence was noted even after 3 months of resection.
