Purpose: Epstein-Barr virus (EBV) infection is related to infectious mononucleosis or nasopharyngeal cancer, and its epidemiology may change according to the socioeconomic development of communities. This study aimed to evaluate the recent epidemiology of EBV seropositive rate in Korea. Methods: We retrospectively reviewed EBV serology test results obtained from a part of clinical care at Samsung Medical Center, Seoul, South Korea, from January 2000 to December 2017. Results: The EBV seropositive rate in 26,527 subjects during the study period was 81.0% (21,485/26,527): 44.4% (2,716/6,122) in subjects aged 0-9 years, 75.8% (2,077/2,739) in those aged 10-19 years, and 94.5% (16,692/17,666) in those aged ≥20 years. The EBV seropositive rate decreased from 89.4% (8,592/9,616) in 2000-2008 to 76.2% (12,893/16,911) in 2009-2017 (P<0.001). Especially, the EBV seropositive rate in subjects aged 0-19 years significantly decreased from 2000-2008 to 2009-2017 (0-9 years, 62.8% [1,172/1,866] in 2000-2008 and 36.3% [1,544/4,256] in 2009-2017; 10-19 years, 83.8% [745/858] in 2000-2008 and 70.8% (1,332/1,881) in 2009-2017) (P<0.001). Conclusions: The EBV seropositive rate in children has decreased in the last 20 years. As the age of patients with primary EBV infection increased, there is a need for interest in clinical manifestation, such as infectious mononucleosis, in adolescents and young adults.

The ultimate objective of periodontal treatment is to get rid of an on-going periodontal disease and further regenerate the supporting tissue, which is already destroyed, functionally. Currently, the bone grafting operation using various kinds of bone grafting materials and the operation for induced regeneration of periodontal tissue using the blocking membrane are performed for regeneration of the destroyed periodontal tissue. However, there are respective limitations Galenical preparations, which are used for regeneration of periodontal of tissue, has less risk of rejective reaction or toxicity that may be incidental to degradation and their effect is sustainable. Thus, in case they are applicable to a clinic, they can he used economically. Chitosan has such compatibility, biological actions including antibacterial activity, acceleration of wound treatment, etc., and excellent mechanical characteristics, which has recently aroused more interest in it. Also, it has been reported that it promotes osteogenesis directly or indirectly by functioning as a matrix to promote migration and differentiation of a specific precussor cell (for example, osteoblast) and further inhibiting the function of such a cell as fibroblast to prevent osteogenesis. In this study, the pure chitosan solution, which was obtained by purifying chitosan, was used. However, since this chitosan is of a liquiform, it is difficult to sustain it in a defective region. It is, therefore, essential to use a carrier for delivering chitosan to, and sustaining it gradually in the defective region. In the calvarial defect model of the Sprague-Dawley rat, it is relatively easy to maintain a space. Therefore, in this study, the chitosan solution with which ACS was wetted was grafted onto the defective region, For an experimental model, a calvarial defect of rat m s selected, and a critical size of the defective region was a circular defect with a diameter of 8 mm. A group in which no treatment was conducted for the calvarial defect was set as a negative control group. Another group in which treatment was conducted with ACS only was set as a positive control group (ACS group). And another group in which treatment was conducted was conducted with by grafting the pure chitosan solution onto the defective region through ACS which was wetted with the chitosan solution was set an experimental group (Chitosan/ACS group). Chitosan was applied to the Sprague-Dawley rat's calvarial bone by applying ACS which was wetted with the chitosan solution, and each Sprague-Dawley rat was sacrificed respectively 2 weeks and 8 weeks after the operation for such application. Then, the treatment results were compared and observed histologically and his tometrically. Thereby, the following conclusions were obtained. 1. In the experimental group, a pattern was shown that from 2 weeks after the operation, vascular proliferation proceeded and osteogenesis proceeded through osteoblast infiltration, and at 8 week after the operation, ACS was almost absorbed, the amount of osteogensis was increased and many osteoid tissue layers were observed. 2. At 2 weeks after the operation, each amount of osteogenesis appeared to be 8.70.8 %, 13.62.3 % and 4.80.7 % respectively in the experimental group, the positive control group and the negative control group. Accordingly, it appeared to be higher in the Experimental group and the positive control group than in the negative control group, but there was no significant difference statistically (p<0.01). 3. At 8 weeks after the operation, each amount of osteogenesis appeared to be 62.26.1%, 17.42.5 % and 8.21.4 % respectively in the experimental group, the positive control group and the negative control group. Accordingly, it appeared to be substantially higher in the experimental group than in the positive control group and the negative control group, and there was a significant difference statistically (p<0.01). As a result of conducting the experiment, when ACS

Objectives: The purpose of this study is to identify the perceived symptoms of oral and temporomandibular joint disorders in adults and to analyze the factors affecting subjective symptoms of temporomandibular joint disorders. Methods: 249 adults over 20 years old who had subjective symptoms of temporomandibular joint disorders were surveyed and analyzed. Independent t-test and ANOVA test were used to examine the relationship between oral habits and temporomandibular joint disorder according to general characteristics. $Scheff{\acute{e}}$ test was used for post-hoc analysis. Multiple regression analysis was conducted to examine the factors affecting oral habits and temporomandibular joint disorder. Results: First, the factors affecting oral and habitual behaviors were married (p<0.05) and monthly income between 1 million~1.9 million won (p<0.001), higher temporomandibular joint disorder (p<0.01) And the degree of habit was increased. Second, the factors affecting temporomandibular joint disorder were increased in occupation (p<0.05) and the degree of oral habit (p<0.01). Conclusions: In conclusion, it was confirmed that oral habit influences temporomandibular joint disorder. Especially, it is suggested that prevention and promotion of temporomandibular joint disorder are needed to recognize the removal of oral habits.

김수경,장성윤,이찬희,Kim, Su Kyoung,Jang, Sungyoon,Lee, Chan Hee 대한자원환경지질학회 2020 자원환경지질 Vol.53 No.2

이 연구에서는 최초의 밭 유구가 발견된 고성 문암리 출토 신석기 전기와 중기의 토기를 대상으로 재료학적 특성과 소성조건을 분석하였다. 문암리 토기는 전기 신석기(BC 4000에서 6000)의 융기문, 죽관문, 무문 또는 주칠 토기와 중기 신석기(BC 3000에서 4000)의 횡주어골문, 단사선문 또는 격자문, 침선문 토기 등 6종으로 세분할 수 있다. 토기의 색도측정 결과, 적색 및 황색도가 높은 것으로 보아 전체적으로 산화소성되었으며 단면에서는 흑심이 관찰되기도 한다. 소성온도는 토기의 문양에 따라 차이는 없으며 800℃ 이하와 800~900℃의 범위를 보이는 두 그룹으로 구분된다. 미세조직 및 X-선 회절분석 결과, 죽관문 토기에서는 흑운모의 견운모화와 봉합선 조직이 발달한 석영 및 변질된 알칼리 장석이 확인되며, 토기의 주요광물은 석영과 알칼리 장석, 흑운모 외에도 녹니석과 각섬석이 동정되었다. 문암리 일대의 지질특성으로 볼 때, 유적의 10km 이내에는 각섬석 흑운모 화강암이 분포하며 변성암이 외곽의 산악지대를 이루고 있어 수계의 영향을 받아 토기의 원료물질인 토층이 산재한다. 이 토층과 토기에 포함된 봉합선상 조직이 발달한 석영으로 보아 변성암 기원의 원료물질이 활용된 것으로 추정된다. 토기의 지구화학적 표준화 결과, 문양에 관계없이 성인적으로 유사하여 신석기 시대의 전기와 중기의 시간적 차이에도 불구하고 유적지 주변의 토양을 사용하여 제작한 것으로 해석된다. This study was carried out material characteristics and firing conditions for some potteries in early and middle Neolithic period at the Munamri sites, where the first farmland remails were found in Korea. It is divided into six kinds of surface patterns for potteries such as the raised, bamboo tube and red painted (patternless) from the early Neolithic period (BC 4000 to 6000), and the patterns of horizontal herringbone, short slanted lined or lattice and incised thick line in the middle Neolithic period (BC 3000 to 4000), respectively. Based on the color measures, redness and yellowness of potteries were relatively high as condition of oxidation firings, were also observed black cores on the cross section of potteries. The firing temperature is divided into two groups having under 800℃ and 800to 900℃, the difference in patterns of the potteries are not confirmed. As a microtextures, the bamboo tube pattern potteries show the sericitization biotite, the quartz have developed a suture line textures, and altered alkali feldspars are occurred. X-ray diffraction analysis shows that the main minerals contained in potteries are chlorite and amphibole besides quartz, alkali feldspar and biotite. Considering the geology around the Munamri area is the biotite amphibole granite and soil layers within 10km radius are used as the raw materials for the potteries. The raw materials are presumed that the sources from the metamorphic rocks along the water systems through the mountains around the sites on the basis of well developed suture line textured quartz in potteries. Results on normalized geochemical compositions, the potteries by surface patterns are very similar to sources, and it is judged that was made by using the surrounding soils despite the long time difference from the early to middle in the Neolithic period.
