Objectives : The aim of this study is to review the effect of acupuncture/moxibustion on vitiligo. Methods : Using 5 databases(Pubmed, EMBASE, Cochrane Library, RISS, OASIS) clinical studies about effect of acupuncture/moxibustion on vitiligo were searched. Only randomized controlled trials(RCTs) were selected to analyze. Results : Total 235 studies were searched. After screening those studies 5 studies were selected from china and Iran. 3 studies used effective rate to measure the effect of acupuncture for vitiligo. 1 study used Vitiligo Area Scoring Index(VASI) and 1 study assessed 4 grade of repigmentation to prove acupuncture's effect on vitiligo. All studies showed repigmentation in acupuncture/moxibustion group. Adverse effects reported in the five studies were temporary erythema, itching, and dryness. Conclusions : These findings suggest that acupuncture and moxibustion can be considered a safe treatment for vitiligo. However, due to the small number of RCTs conducted on acupuncture and moxibustion for vitiligo, more RCTs should be conducted to confirm the effectiveness of acupuncture and moxibustion for vitiligo.

본 연구는 NOAA/AVHRR 인공위성 자료를 이용하여 우리 나라 금강유역에 대한 순일차생산량(NPP, Net Primary Production)을 평가하는 것이다. 이것은 순일차생산량과 자연식생과의 사이에 선형관계가 성립한다는 가정에 근거하고 있다. 자연식생의 순일차생산량은 연간 순방사량(Rn)에 비례하여 증가하며 방사건조도(RDI)는 순방사량과 순일차생산량과의 관계를 규정하는 비례상수로 사용된다. 정규화식생지수(NDVI)와 이의 적산치인 iNDVI는 식생의 변화를 모니터링하기 위한 수단으로 사용된다. iNDVI는 순방사량과 순일차생산량과 밀접한 관련이 있는 것으로 알려져 있으며 이로부터 특히 기상자료의 수집이 불가능한 지역에서의 순일차생산량 추정에 유용하게 사용될 수 있다. 이에 본 연구에서는 이와같은 이론에 근거하여 금강유역에 대한 순일차생산량의 분포를 산정하는 방법을 개발하여 제안하고자 한다.

This study investigates the physical mechanisms that contributed to the 2022 European record-breaking heatwave throughout May-August (MJJA). The European climate has experienced surface warming and drying in the recent decade (1979~2022) which influences the development of the 2022 European heatwave. Since its spatial pattern resembles the 2003 European heatwave which is a well-known case developed by the strong coupling of near-surface conditions to land surface processes, the 2022 heatwave is compared with the 2003 case. Understanding heatwave development is carried out by the European Centre for Medium-Range Weather Forecasts (ECMWF) Reanalysis version 5 (ERA5) and daily maximum surface temperature released by NCEP (National Centers for Environmental Prediction) CPC (Climate Prediction Center). The results suggest that the persistent high pressure along with clear sky tends to increase the downward shortwave radiation which leads to enhanced sensible heat flux with the land surface dryness. Terrestrial Coupling Index (TCI), a process-based multivariate metric, is employed to quantitatively measure segmented feedback processes, separately for the land, atmosphere, and two-legged couplings, which appears to the development of the 2022 heatwave, can be viewed as an expression of the recent trends, amplified by internal land-atmosphere interactions.

천연보습인자(NMF, natural moisturizing factor)는 정상 피부 내의 각질층에 존재하는 수용성, 친수성 성분을 총칭하는 말로 외부로부터 수분을 흡수하고 각질층의 수분보유능을 증가시키며 피부가 건조해지는 것을 방지하여 피부의 유연성과 가수성을 유지하는 기능을 한다. NMF는 주로 아미노산과 아미노산의 대사산물로 구성되며 이들은 필라그린(filaggrin)이 분해되면서 생성된다. 본 연구에서는 피부 각질층의 22종의 개별 아미노산의 함량분석을 통하여 피부보습능과 개개의 아미노산과의 상관관계를 연구하였다. 15명의 건강한 지원자들의 전박과 이마로부터 tape stripping한 각질 시료 중 22종의 아미노산 함량을 UPLC-PDA를 이용하여 동시 분석하였다. 그 결과 각질 표면보다는 안쪽에서의 아미노산들의 함량이 높음을 확인하였다. 또한 신체 부위별 비교에서 전박이 이마에 비해 아미노산 함량이 1.5배 정도 높음을 확인하였다. 전박부위의 아미노산 총 함량과 보습능(TEWL)과의 상관 관계분석을 통해서는 보습능이 클수록 총아미노산 함량이 높은 것으로 확인되었으며 특히 Ser, Glu, Gly, Ala 및 Thr은 각질 내 존재하는 주요 아미노산 성분으로 보습에 긍정적인 영향을 주는 성분으로 확인되었다. 이상의 결과로써 NMF의 주성분인 아미노산의 함량은 각질 생리기능과 밀접한 관련을 가지고 있음을 확인할 수 있었으며 본 연구를 통해 얻은 각질층의 아미노산의 통합적인 분석법은 보습, 노화, 미백, 피부 염증질환 등 다양한 피부 상태와 아미노산류들의 변화와의 관계를 깊이 이해하고 피부 기능과 관련된 새로운 분자적 타겟을 발굴하고 증명하는데 기초적인 방법으로써 사용될 수 있을 것으로 사료된다.

본 연구에서는 GDAPS(Global Data Assimilation and Prediction System) 예보모델자료와 위성기반 식생건조지수를 결합시킨 산불위험지수 WRI(Wildfire Risk Index)를 개발하였고, 이를 2019년 4월 4일의 고성-속초 산불과 강릉-동해 산불 사례에 적용해 보았다. 제시한 산불위험지수 WRI는 강수 이벤트 후에 건조 경향이 지속되었던 3월 19일 전후와 4월 4일 전후의 산불위험도 변화를 잘 나타냄으로써, 그 적합성이 확인되었다. WRI는 우리나라 산불취약성의 상시 감시를 위한 하나의 방법이 될 수 있을 것이며, 이를 더욱 발전시키기 위해서는 향후 GK-2A 위성자료의 활용과 함께, 산림청의 산불위험예보시스템과의 연계 방안에 대한 모색이 반드시 필요할 것이다.

Objectives: Fatigue is a common symptom experienced by many people who visit Oriental medical clinics or hospital. However, there has been little study about the fatigue in the Oriental medical academic world. For this reason, we attempted to investigate the present status of fatigue of outpatients, and its relation with Health Practice Index(HPI). Methods: The subjects were 63 outpatients who visited the Tonification Clinic in Kyunghee Oriental Medical Center between January 1, 2001 and July 31, 2001. Their chief complaint was fatigue and they did not have any physical or mental problem. They were given a questionnaire which included questions reflecting general characteristics, fatigue degree and health habits. We measured degree of fatigue by Chalder scale et al. Health habits were investigated about 5 articles out of 'Breslow 7 Health habits'. Results: Among the subjects, 48 people(76.2%) were considered as 'fatigue patients' by the Chalder scale. Of this 48 fatigue patients, 27 people(56.3%) had manifested fatigue for more than 6 months. The average of scale II for all the patients was 14.05, which indicates moderate degree of fatigue. They complained fatigue, drowsiness and general weakness, dryness and discomfort of the eyes, headache, shoulder pain and neck stiffness, dizziness, heat in the upper part of the body, and poor concentration. There were no differences in degree of fatigue according to Health habits including exercise or not, smoking or not, the frequency of drinking, hours of sleeping, and body mass index. Conclusions: Many people complain fatigue symptom. Therefore doctors should have more interest in fatigue and care. This study can provide standards of prognosis of fatigue patients. Also prospective studies are needed to find relationship between health habits and fatigue degree.

Using high-resolution stereoscopic aerial images (in 2008, 2012 and 2016), we conducted to analyze the spatial characteristics affecting evergreen coniferous die-off in the northwestern ridge (major distribution area such as Abies nephrolepis), Seoraksan National Park. The detected number of dead trees at evergreen coniferous forest (5.24㎢) was 1,223 in 2008, was 2,585 in 2012 and was 3,239 in 2016. The number of cumulated dead trees was 7,047 in 2016. In recent years, the number of dead trees increased relatively in the northwest ridge, Seoraksan National Park. Among the analysed spatial factor (altitude, aspect, slope, solar radiation and topographic wetness index), the number of dead trees was increased in the conditions with high altitude, steep slope and dry soil moisture. A spatial distribution of dead tree was divided into 2 groups largely (high altitude with high solar radiation, low altitude with steep slope). In conclusion, the dead trees of evergreen coniferous were concentrated at spatial distribution characteristics causing dryness in the northwestern ridge, Seoraksan National Park.
