  • Background: Varicella is the most common infectious disease reported despite the high vaccination rate. Interventions that target humans are particularly effective for varicella because humans are its only natural host. On the other hand, the existing national varicella surveillance systems lack the information to identify an outbreak. Therefore, a new index to assess varicella outbreaks was developed. Methods: The residential addresses of 2,718 varicella cases reported in Daegu in 2016 were converted to geographic coordinates and the distances between new varicella case and previous cases within 21 days were calculated from the date analyzed. Two cases were considered to be adjacent if the distance between them was less than 1 km. Finally, a proximity index was introduced by dividing the number of adjacent cases by the number of new cases on the date analyzed. Results: First, time-series charts and scatter plots were used to verify that the proximity index reflected the spatial closeness of the different varicella cases. The proximity index is helpful in identifying outbreaks from a list of single varicella cases. In addition, in this study, a new epidemic characteristic of varicella based on the proximity index was shown. Conclusion: The proximity index introduced in this study can be used to determine the likelihood of an outbreak from a single case of varicella, and it can be embedded in a web-based national varicella surveillance system that is currently in operation.

  • The purpose of this study is to develop a publicness evaluation index for indoor privately owned public spaces (POPS). In order to develop the index, 10 cases of indoor POPS in New York City were analyzed using Visibility Graph Analysis by evaluating its accessibility and visual openness. The results are as follows; (1) Accessibility and openness of indoor POPS were higher compared to other public spaces on the first floor. (2) Cases with high accessibility index installed a higher number of entrances. (3) Cases with high openness index were mostly composed of a glass wall. (4) The publicness index was high when the lobby and the indoor POPS are shared. (5) Atrium types were highly utilized and the evaluation index was also high whereas, linear types were less utilized and the evaluation index was lower.

  • Chiefly, painful heel syndrome is observed at old age. Many possible reasons were bursitis, plantar fasciitis, calcaneal periostitis around the calcaneus and achilles tendon. But the exact cause was not clearly identified due to complexity of subcalcaneal pain mechanism. The incidence of calcaneal spur and overweight were significant in painful heel syndrome. Our purpose of this study was analysis of underlyng cause and correlation about bony spur and overweight in painful heel syndrome. The author used incidence of heel spur on painful heel syndrome and body mass index to evaluate overweight. The material is 55 cases of painful heel syndrome patients and 60 cases of control group. Bony spur was one of the cause of painful heel syndrome. Body weight and calcaneal spur was developing factors on painful heel syndrome. And the result was as follows. 1. Spur formation incidence is 35 cases (63.6 %) in painful heel syndrome, 8 cases (13.3%) in normal control group. So, patient's group is significantly high (p<0.01). 2. Body mass index is 26.48 in painful heel syndromes, 21.75 in normal control groups. Overweight above index 27 is 22 cases (40%) in painful heel syndromes, 3 cases (5%) m normal control groups. So, patient's group is significantly high (p<0.01). 3. In painful heel syndrome, tenderness site is 46 cases (83.6%) in medial calcaneal tuberosity, 4 cases (7.3%) in central calcaneal tuberosity, 1 cases (1.8%) in both site. 4. Underlying causes of painful heel syndrome is 19 cases (34.5%) in plantar fasciitis, 16 cases (29.1%) in calcaneal periostitis, 11 cases (20%) in bursitis, 4 cases (7.3%) in tendinitis, 2 cases (3.6%) in entrapment neuropathy.

  • 가뭄은 영향을 받는 인자에 따라 체감정도가 달라지는 사회적 현상으로 기후학적 가뭄, 기상학적 가뭄, 농업적 가뭄, 수문학적 가뭄 등 다양한 상대적 개념으로 정의되고 있다. 본 연구에서는 다양하게 정의되는 가뭄 중에서 기상학적 가뭄을 나타내는 지수에 대한 비교 분석을 실시하고자 하였으며, 실제 과거 가뭄사례와 기상학적 가뭄지수 분석결과의 비교를 통하여 가뭄지수의 적용성을 검토하고자 하였다. 가뭄지수의 비교를 위하여 기상학적 가뭄을 판단하기 위해 일반적으로 가장 많이 사용되는 SPI (Standardized Precipitation Index)와 일반적으로 사용되지는 않지만 강수량만을 이용하여 가뭄분석이 가능한 CZI (China-Z Index), MCZI (Modified CZI), ZSI (Z-Score Index) 지수를 이용하였다. 대상지역으로는 최근까지도 가뭄이 발생하였던 태백과 속초지역을 대상으로 선정하였으며 1986년부터 2015년 기상 자료를 이용하여 지속시간 3개월로 가뭄지수 분석을 실시하였다. 분석 결과 SPI 가뭄지수가 과거 제한급수발생 가뭄사례에 대하여 높은 재현성을 나타내는 것으로 분석되었으며 CZI와 MCZI 가뭄지수의 경우 Extreme Dry 발생 횟수는 과거사례와 유사하나 실제 가뭄이 발생했던 년도에 대해서는 낮은 재현성이 나타났다. ZSI 가뭄지수의 경우 발생횟수, 과거사례와의 비교 모두 재현성이 떨어지는 것으로 분석되었다. 가뭄지수의 비교결과 강수량을 이용한 기상학적 가뭄지수의 경우 과거 가뭄사례와 가장 높은 재현성을 보이는 SPI 가뭄지수를 이용하는 것이 효과적일 것으로 판단된다.

  • We report a measurement of the effective refractive index of a nematic liquid crystal (NLC) inside a Fabry-Perot (FP) etalon according to the applied electric fields. The effective refractive index of the NLC depends on the intensity of the applied electric field. A wavelength-swept laser with a polygon-scanner-based wavelength filter is used as a wide-band optical source to measure the effective refractive index of the NLC. The bandwidth of the optical source is greater than 90 nm around 1300 nm. The fabricated NLC FP etalon consists of glass substrates, gold layers as the electrodes with highly reflective surfaces, polyimide layers as the planar alignment layers, and an LC layer. Furthermore, we measured the Freedericksz transition voltages for three types of NLC FP etalons having thicknesses of $30.6{\mu}m$, $55.4{\mu}m$, and $108.8{\mu}m$. The Freedericksz transition voltages in the three cases are nearly equal. The measured effective refractive indices in the three cases decreased from 1.67 to 1.51 as the applied electric field intensity was increased. Beyond the threshold electric field, the effective refractive indices quickly decreased and eventually saturated at a value of 1.51 for all cases.

  • 목 적: 홍역, 유행성이하선염 및 풍진 예방접종 시행후 연령 증가에 따른 항체양성율의 변화를 조사한다. 방 법: 병원에 내원한 7-20세의 환아를 대상으로 잔여 혈청을 이용하여 IgG 항체를 검사하였다. 결 과: 총 408례 중 홍역은 275례로 67.4%, 유행성이하선염은 112례로 27.5%, 풍진은 367례로 90.0%의 양성율을 보였다. 양성자의 IgG 수치는 각각 $2.77{\pm}1.18$ Index, $2.08{\pm}1.29$ Index 및 $60.46{\pm}63.47$ IU/mL 이었다. 결 론: 홍역 67.4%, 유행성이하선염 27.5% 및 풍진 90.0%의 IgG 항체 양성율을 보였다. 홍역, 유행성이하선염 및 풍진의 유행을 막기 위해서는 높은 접종율의 유지가 중요하며, 또한 보호자에 대한 접종기록 등의 관리가 중요할 것으로 생각된다.

  • Objectives : This study was aimed to evaluate the correlation between changes in disease severity and serum total IgE or eosinophil count in individual patients of atopic dermatitis depending on the change of severity. Methods : We performed a retrospective chart review of 8 cases of atopic dermatitis who underwent blood tests more than five times. Disease severity was assessed by objective SCORing of Atopic Dermatitis index (OSI). Blood tests include serum total IgE, eosinophil counts, aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and serum creatinine (SCr). In each subject, on the day that the blood test was performed, OSI was also assesed by a same physician. Correlation between OSI and total IgE or eosinophil count was analysed by nonparametric correlation analysis. Results : There was a statistically significant positive correlation between OSI and total IgE in three cases and a positive correlation between OSI and eosinophil count in two cases. In other three cases, there were no significant correlation. There were no cases that OSI correlated with total IgE and eosinophil count at the same time. In all cases, AST, ALT, BUN and SCr were stable. Conclusions : We suggest that total IgE and eosinophil count may reflect the severity of atopic dermatitis differently in individual patients. We also suggest that total IgE and eosinophil counts may be used as biomarkers to predict the severity of atopic dermatitis in some patients depending on the underlying pathology.

  • Objectives: The Purpose of this study is to report the effects of Ondam-tang gagambang on menopause syndrome. Methods: Four patients who had menopause syndrome as chief complaints were treated by Gamiondam-tang or Kuibiondam-tang for two weeks. We evaluated the results of treatment by change of symptoms, Kupperman's Index and Menopause Rating Scale (MRS). Results: After treatment, menopause syndrome cases were improved. Almost scores of Kupperman's Index & Menopause Rating Scale (MRS) were reduced. Conclusions: This study suggests that Ondam-tang gagambang is effective on overall Menopause syndrome cases.
