Strain E4, an unrecorded species of dimorphic fungi, was isolated from the gut of earthworms collected in Gyeonggi Province, South Korea. Nucleotide sequence analysis of the D1/D2 region of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) region revealed that this species is a member of the genus Blastobotrys, Blastobotrys illinoisensis. Strain E4 differed from its closest known species, B. mokoenaii and B. malaysiensis, by harboring 3-5 and 12-14 nucleotide substitutions in the D1/D2 and ITS regions, respectively. Phylogenetic analysis based on concatenated sequences of the D1/D2 region of the LSU rRNA gene and the ITS region also indicated that strain E4 belongs to the Blastobotrys clade and is distinct from other related species in the clade. The previously unreported isolate could be distinguished from closely related species by its inability to ferment carbon sources. To our knowledge, this is the first report on the isolation of Blastobotrys species from the gut of earthworms in Korea. The strain used was E4 (=KCTC 27831=JCM 33428).

This study were to simulate major criteria air pollutants and estimate regional source-receptor relationship using air quality prediction model (TAPM ; The Air Pollution Model) in the Seoul Metropolitan area. Source-receptor relationship was estimated by contribution of each region to other regions and region itself through dividing the Seoul metropolitan area into five regions. According to administrative boundary, region I and region II were Seoul and Incheon in order. Gyeonggi was divided into three regions by directions like southern(region III), northern(IV) and eastern(V) area. Gridded emissions ($1km{\times}1km$) by Clean Air Pollicy Support System (CAPSS) of National Institute of Environmental Research (NIER) was prepared for TAPM simulation. The operational weather prediction system, Regional Data Assimilation and Prediction System (RDAPS) operated by the Korean Meteorology Administration (KMA) was used for the regional weather forecasting with 30km grid resolution. Modeling period was 5 continuous days for each season with non-precipitation. The results showed that region I was the most air-polluted area and it was 3~4 times more polluted region than other regions for $NO_2$, $SO_2$ and PM10. Contributions of $SO_2$ $NO_2$ and PM10 to region I, II and III were more than 50 percent for their own sources. However region IV and V were mostly affected by sources of region I, II and III. When emissions of all regions were assumed to reduce 10 and 20 percent separately, air pollution of each region was reduced linearly and the contributions of reduction scenario were similar to those of base case. As input emissions were reduced according to different ratio - region I 40 percent, region II and III 20 percent, region IV and V 10 percent, air pollutions of region I and III were decreased remarkably. The contributions to region I, II, III were also reduced for their own sources. However, region I, II and III affected more regions IV and V. Shortly, graded reduction of emission could be more effective to control air pollution in emission imbalanced area.

Purpose: This study reports on limb amputations in diabetic patients according to gender, age, and region based on the data from the Korean Health Insurance Review & Assessment Service. Materials and Methods: The number of amputations was compared by region, age, gender, and year, as well as by femoral region, lower leg, foot, and toe in diabetic patients who received limb amputation. This analysis was performed based on the data from the Korean Health Insurance Review & Assessment Service, between January 2009 and December 2014. Results: The total number of amputations between the study period was 9,155. The number of patients who were treated at hospitals for diabetes in 2009 was 1.9 million, among which, 1,214 patients underwent amputation. In 2014, the incidence of diabetes was 1,747 in 2.58 million individuals. With this rising incidence of diabetes, the amputation of limbs due to diabetes is increasing every year. In particular, the following regions were amputated more often: femoral region, 2.3%; lower legs, 19.6%; feet, 18.1%; and toes 60.0%. Regarding gender differences, males showed a higher amputation rate than females for all body parts. With respect to region, Seoul was the highest with 30.2%, followed by Gyeonggi with 19.9%, and Busan with 8.8%. According to age, older age showed greater diabetic amputation rate. Conclusion: In accordance with the rising incidence of diabetes, the diabetic amputation is also increasing. Here, we showed that toes were amputated with the highest percentage and males had greater amputation rate than females for all body parts. Moreover, amputation rate was highest in older diabetic patients, especially for those in their seventies. Additionally, Seoul was the region with highest amputation rate.

본 연구는 일일 인구이동에 의한 네트워크와 유동패턴을 통해 한국의 도시체계 변화를 고찰하였다. 일일 인구이동이 일상적인 통행패턴을 반영하므로, 도시간 연결관계에 의한 도시체계는 생활권의 관점으로 인식할 수 있다. 2012년 들어 도시간 인구이동이 증가하면서, 도시 네트워크의 연결체계를 비롯하여 출발지와 도착지로 구성되는 통행권의 수가 모두 증가하였다. 통행량의 분산에도 불구하고 서울을 중심으로 하는 수도권과 부산을 중심으로 하는 부산권의 공간범위는 확대되었다. 서울지향형 고속교통망이 구축된 강원도에서는 춘천을 중심으로 하는 소양강문화권과 영동지방의 생활권 분리가 심화되었다. 교통망의 접근성이 양호한 대전과 그 주변지역을 아우르는 생활권은 경기남부까지 확대되었다. 전남에 형성된 기존의 생활권은 광주의 중심성이 약화되면서 목포와 순천을 중심으로 서부와 동부에서 분절되었다. 생활권은 거시적으로 광역 행정경계와 대체로 일치하였지만, 도 경계를 넘어 다른 광역단체의 시군과 통합되는 사례가 증가하였다. 서울과 그 주변 도시간의 상호작용이 강화된 것은 서울을 중심으로 하는 세계도시-지역의 발전 가능성을 높여준다.

Background: Humidifier disinfectant is a biocidal product used in the water tanks of humidifiers to prevent the growth of microorganisms. Although there are a huge number of cases of reported humidifier disinfectant-related health effects across the entire Korean population, their numbers are distributed differently depending on the region. Objectives: This study aimed to investigate the regional distribution of enrollment cases who reported humidifier disinfectant-related health effects. Methods: This study used data on 6,240 subjects who experienced humidifier disinfectant-related health effects and who enrolled their cases which is conducted by the Korea Ministry of Environment. We examined the regional distribution of the enrolled cases based on sixteen administrative divisions and assessed the: 1) crude number; 2) proportional rate; and 3) age-standardized proportional rate of enrollment by region. Results: When we examined the crude number of enrollments by region, the highest number were in Gyeonggi-do Province (n=1,896), followed in order by Seoul (n=1,405), Incheon (n=436) Busan, Daegu, Gyeongsangnam-do Province, Daejeon, Chungcheongnam-do Province, Gyeongsangbuk-do Province, Jeollabuk-do Province, Gwangju, Chungcheongbuk-do Province, Gangwon-do Province, Jeollanam-do Province, Ulsan, and Jeju-do. When we examined proportional rate of the regional enrollment (cases per 100,000 population), Daejeon (n=16.2) was the region with the highest rate, followed in order by Gyeonggi-do Province (n=16.1), Incheon-do Province (n=15.9), Seoul, Daegu, Gwangju, Jeollabuk-do Province, Chungcheongnam-do Province, Busan, Chungcheongbuk-do Province, Gangwon-do Province, Gyeongsanbuk-do Province, Gyeongsangnam-do Province, Ulsan, Jeju-do, and Jeollanam-do Province, which is inconsistent with the order in terms of crude numbers. However, when we examined the age-standardized proportional rate of regional enrollment (cases per 100,000 population), their ranked distribution is consistent with the crude rate. Conclusions: This study observed that the regional distribution of the enrolled cases who reported humidifier disinfectant-related health effects is inconsistent with the regional distribution of the proportional rate of enrollment cases, which may be caused in part by the volume of the inherent population of each region.
