Objectives : The aim of this investigation was to evaluate the remineralization effect of Bamboo salt and NaF+Bamboo salt solutions on bovine enamel formed incipient artificial enamel caries by microcomputed tomography (micro CT). Methods : Experimental solutions were distilled water(negative control), 2% sodium fluoride solution (2% NaF group), 3% bamboo salt solution (3% BS group) and the solution mixed 2% sodium fluoride solution and 3% bamboo salt solution (2% NaF+3% BS group). Specimens were prepared from extracted bovine teeth and divided into 4 groups of 10 specimens each by randomized blocks according to density. Then the specimens surface were divided equally into three parts to observe sound enamel area, incipient enamel carious area and remineralized enamel area. Only one-third of specimen surface was coated with nail varnish and these were exposed to a lactate carbopol buffer system for 72 hours. Then one-half of the demineralized enamel area was coated with nail varnish. The specimens were carried out under pH cycling model for 14 days as follows; samples were immersed in each experimental solution for 2 mins 3 times per day, demineralized for 4 hours and in mixed saliva for the remaining hours. After pH cycling, density was measured using micro CT. Results : All experimental groups showed remineralization effects except for negative control group(p<0.05). The differences of density after experimental solution treatment were statistically significant difference among 4 groups (p<0.01). The density difference values of groups were $0.04{\pm}0.01$ in negative control group, $0.19{\pm}0.01$ in 2% NaF group, $0.14{\pm}0.01$ in 3% BS group, and $0.21{\pm}0.01$ in 2% NaF+3% BS group. Conclusions : The bamboo salt solution showed remineralization effects on incipient artificial enamel caries and the solution mixed sodium fluoride solution and bamboo salt solution showed more remineralization effects than the bamboo salt solution. Thus, it is suggested that bamboo salt can be used as remineralization agent in incipient enamel caries lesion.

Problems and current situation of public health globally and domestically were analyzed in this study and based on these findings, ways to improve from western medicine and Oriental medicine can be deduced as follows: 1. Current problems of public health in Korea and the world 1) Increase of diseases resulted from daily habits and infectious diseases, many are at the brink of being ill. Quality of life from extended life span and unbalanced health care must be solved. 2) Natural and societal factors including host factors, public health service, and other external and internal factors play an important role in deciding healthy and being ill. 3) Some of the limits and problems of modem medicine include insufficient academic knowledge and incomplete theory, as well as misled approach to the treatment. Human itself isn't perfect organism and other realistic problems hinder one's well-being. 4) Regardless of western medicine or Oriental medicine, patients were approached as someone with diseases and disorders, and wholistic approach was disregarded. Lack of clinical training, absence of clear educational philosophy and goal are some of the reasons why the education isn't under concrete system 2. Important factors for the medical education and proper direction for the education of Oriental medicine 1) Important factors for medical education - Education should not be limited on the human health and illness, but also cover qualities such as well-being, social welfare, service, and happiness. Every aspects of human life must be considered and attended for more productive outcome. - Basic understanding of humanity must be included in the educational curriculum - Foundation of human diseases and pain are associated with inner life and surrounding causes including family, society, nature, race, culture, religion, politics, and etc., thus the education must be approached to recognize aforementioned criteria. 2) Proper direction for the education of Oriental medicine - Values of Oriental medicine for medical principles and importance of lifehood must be educated. - Educational goal, limits, and levels must be established for the school of Oriental medicine - Respect for life must be the top priorities of educational direction which should lead to solution based education for the human health. Latest medical theory and technology should be accommodated as well as prevention, treatment, and balancing of basic courses and clinical training for optimal education.

Article 10 of the Constitution All citizens have dignity and values as humans and have the right to pursue happiness. There is a need for support measures such as a means to realize the respect of dignity and values as humans, and how to efficiently maintain policies on welfare for the elderly classified as the socially disadvantaged. It was considered necessary to develop an elderly-friendly city for economic, physical, and social life. Dasan Jeong Yak-yong's respect for adults was to practice the ideology of Confucianism, so this was the most important thing in the past Joseon Dynasty. In particular, it was considered important to think of adults first in practicing filial piety.This study focuses on the long-term care insurance system for the elderly, one of the welfare policy measures for the elderly. The significance of implementing the long-term care insurance system for the elderly is to benefit not only the elderly, but also all generations, including the middle-aged and children who were in charge of long-term care. To this end, the government should properly manage the factors of the social insurance financial crisis caused by the low birth rate and aging population.In addition, concerns about health insurance are high, so it is necessary to secure an appropriate level of government budget for health insurance financial management and minimize unnecessary non-benefit. In addition, it is necessary to induce appropriate medical use through connection with construction medical insurance.

본 연구는 지속가능개발목표(Sustainable Development Goals) 하에 보편적 건강보장(Universal Health Coverage) 달성을 목표로 전 국민의 건강보험 가입을 추진하고 있는 베트남의 보건의료 부문에 주목하여 보건의료 체계와 건강보험법의 개혁 과정에서 나타난 특징을 역사 문화적 맥락을 통해 파악해보고 개발의 관점에서 그 함의를 살펴보고자 한다. UHC의 세 가지 차원, 즉 인구 집단에 대한 보장성 확대, 다양한 의료서비스 제공, 그리고 재정적 보호를 기준으로 베트남 보건의료 부문의 현황을 요약하면 다음과 같이 정리할 수 있다. 첫째, 2015년 발효된 개정 건강보험법에서 가구 단위의 의무 가입과 그에 따른 건강보험료 정산 방식이 새로운 제도로 시행되고 있다는 점이다. 둘째, 1차 의료시설, 즉 사($X{\tilde{a}}$, Commune)급 단위의 보건소를 중심으로 예방 및 건강관리 서비스를 제공할 수 있는 의료 네트워크가 구축되어 있다는 점이다. 셋째, 의료보험법 및 다양한 제도 시행 이후 공공 지출이 증가하고 민간 지출이 감소하고 있지만 여전히 본인부담 의료비 지출(Out-of-Pocket Expenditure)이 많은 비중을 차지하고 있다는 점이다. 베트남의 사회건강보험 개혁은 현재 과도기이다. 따라서 베트남은 보건의료 체계와 건강보험 제도를 어떻게 구축해 나갈 것인가에 대한 문제가 더욱 중요할 수밖에 없는 시기적 상황에 당면해 있다. 제도와 체계에 대한 개발은 효율성보다는 그것을 고스란히 감당해내야 하는 주체, 즉 해당 사회의 구성원들에게 적절하고 정당한 방식으로 설계되어야 한다. 본 연구는 제도와 문화, 즉 제도를 공유하는 사회적 가치, 가족 문화 그리고 비공식적인 제도 등과의 상호작용 등으로부터 그 함의를 이끌어내고자 하였다.

Since 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly, infecting millions of people worldwide. On March 11, 2020, the World Health Organization declared coronavirus disease (COVID-19) a pandemic owing to the worldwide spread of SARS-CoV-2, which created an unprecedented burden on the global healthcare system. In this context, there are increasing concerns regarding co-infections with other respiratory viruses, such as the influenza virus. In this study, clinical data of patients infected with SARS-CoV-2 and other respiratory viruses were compared with patients infected with SARS-CoV-2 alone. The hematology and blood biochemistry results of 178 patients infected with SARS-CoV-2 , who were tested on admission, were retrospectively reviewed. In patients with SARS-CoV-2 and adenovirus co-infection, C-reactive protein levels were elevated on admission, whereas lactate dehydrogenase (LDH), prothrombin time, international normalized ratio, activated partial thromboplastin clotting time, and bilirubin values were all within the normal range. Moreover, patients with SARS-CoV-2 and human bocavirus co-infection had low LDH and high bilirubin levels on admission. These findings reveal the clinical features of respiratory virus and SARS-CoV-2 co-infections and support the development of appropriate approaches for treating patients with SARS-CoV-2 and other respiratory virus co-infections.

This study was carried out to estimate effects of sediment reduction with net type sediment settling pond at highland agricultural areas. Flow and sediment monitoring system with rainfall gauge were installed at the study area for real-time monitoring and analysis. It was found that amount and intensity of rainfall events strongly affect sediment yield from the study area. With net type sediment settling pond, it was expected that approximately 61% of sediment could be removed. The correlation between heavy metals and SS were analyzed in this study. $R^2$ values were 0.644, 0.876, 0.945, and 0.928 for Fe, Mn, Al, and Si, respectively. This results indicate that heavy metals also could be removed with net type sediment settling pond. As shown in this study, the sediment settling pond will be an efficient sediment reduction facility at highland agricultural areas. For maximum reduction efficiencies of sediment and other pollutants at agricultural fields, simplified sediment settling pond should be designed and implemented.

PURPOSE. The purpose of this study was to evaluate the marginal and internal gaps of Ni-Cr and Co-Cr copings, fabricated using the dental ${\mu}-SLA$ system. MATERIALS AND METHODS. Ten study dies were made using a two-step silicone impression with a dental stone (type IV) from the master die of a tooth. Ni-Cr (NC group) and Co-Cr (CC group) alloy copings were designed using a dental scanner, CAD software, resin coping, and casting process. In addition, 10 Ni-Cr alloy copings were manufactured using the lost-wax technique (LW group). The marginal and internal gaps in the 3 groups were measured using a digital microscope ($160{\times}$) with the silicone replica technique, and the obtained data were analyzed using the non-parametric Kruskal-Wallis H test. Post-hoc comparisons were performed using Bonferroni-corrected Mann-Whitney U tests (${\alpha}=.05$). RESULTS. The mean (${\pm}$ standard deviation) values of the marginal, chamfer, axial wall, and occlusal gaps in the 3 groups were as follows: $81.5{\pm}73.8$, $98.1{\pm}76.1$, $87.1{\pm}44.8$, and $146.8{\pm}78.7{\mu}m$ in the LW group; $76.8{\pm}48.0$, $141.7{\pm}57.1$, $80.7{\pm}47.5$, and $194.69{\pm}63.8{\mu}m$ in the NC group; and $124.2{\pm}52.0$, $199.5{\pm}71.0$, $67.1{\pm}37.6$, and $244.5{\pm}58.9{\mu}m$ in the CC group. CONCLUSION. The marginal gap in the LW and NC groups were clinically acceptable. Further improvement is needed for CC group to be used clinical practice.

진단서는 의사등이 진찰결과에 관한 판단을 표시하여 작성하는 문서로서 민 형사소송 등에서 증거로 쓰인다. 특히 상해의 증명에서 그 기능이 현저하다. 법은 허위진단서작성을 형사처벌하는 등으로 그 증명기능을 보호하기 위하여 힘쓰고 있다. 그러나 몇 가지 이유에서 진단서가 진실과 부합하지 아니하는 경우가 생긴다. 첫째, 의사등의 제1차적 관심은 환자의 효과적인 진단과 치료인데, 그에 필요한 정보수집 및 판단의 방법이 법정 등에서 진실을 찾는 것과 다를 수 있다. 둘째, 의사등은 종종 환자의 진술 등에서도 판단에 필요한 정보를 얻는데, 환자와의 치료적 대화 관계 등의 유지를 위하여 그 진술 등의 신빙성을 의심하는 것이 부적절한 경우가 있을 수 있다. 이는 결국 의사등이 증명이 아닌 다른 목적으로 수집한 정보로부터 내린 판단을 증명에 전용(轉用)하여 생긴 문제이고, 비용이 낮은 진단서 제도를 버릴 수 없는 한 불가피한 한계에 해당한다. 진단서에 의한 증명에 표현증명의 효력을 부여하여야 하는 경우와 그 증명력을 자유심증주의에 터 잡아 개별적으로 심사하여야 하는 경우를 나누어 후자에 대하여는 전면적인 증명력 심사를 가하고, 진단서 서식 자체를 개선하여 법원이나 수사기관 등이 위 둘 중 어느 경우에 해당하는지를 가리는 데 필요한 정보가 이미 진단서 자체에 드러나게 하는 개선이 필요하다.
