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.

This study is to evaluate the NPP (Net Primary Production) distribution in the Geum River basin from NOAA/AVHRR satellite imagery data. It is supposed that the natural vegetation condition and the NPP has the linear relationship. The NPP from natural vegetation increases proportional to the annual net radiation (Rn), where radiative dryness index (RDI) is a proportional constant connecting net radiation to NPP. Normalized Difference Vegetation Index (NDVI) is used for monitoring vegetation change, and iNDVI (integrated NDVI) for annual analysis. The iNDVI has a close relation to Rn and NPP, which can be used effectively for estimating NPP distribution of where the meteorological data is unavailable. The purpose of this study is to propose a simple method to get NPP in the Geum river basin.

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.

Natural moisturizing factors (NMFs) are hydrophilic and water-soluble components in stratum corneum of the skin. NMFs absorb water from outer environment and enhance the water-holding capacity of stratum corneum and thereby, prevent the dryness and increase flexibility and plasticity of skin. NMFs are mainly composed of amino acids and their metabolites that are produced from the degradation of filaggrin. Here we established a simultaneous quantification method for 22 amino acids in tape-stripped stratum corneum samples using UPLC-PDA. With this method, we analyzed amino acid contents from tape-stripped stratum corneum samples of forearm and forehead regions from 15 healthy volunteers. Amino acid contents of inner (or upper) region were higher than outer (or lower) region of stratum corneum. Amino acid contents of stratum corneum of forearm were higher by 1.5 fold than forehead region. Of note, total amino acid contents were significantly and inversely correlated with trans-epidermal water loss (TEWL), an index for skin barrier function. Especially, Ser, Glu, Gly, Ala and Thr were determined to positively affect skin mositurizing activities. In conclusion, we could demonstrate that amino acid contents of stratum corneum are closely linked with skin barrier and moisturizing function, providing an important and fundamental methodology for the study of amino acids in skin physiology.

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.

The application of satellite imageries has increased in the field of hydrology and water resources in recent years. However, challenges have been encountered on obtaining accurate evapotranspiration and soil moisture. Therefore, present researches have emphasized the necessity to obtain estimations of satellite-based evapotranspiration and soil moisture with related development researches. In this study, we presented the research status in Korea by investigating the current trends and methodologies for evapotranspiration and soil moisture. As a result of examining the detailed methodologies, we have ascertained that, in general, evapotranspiration is estimated using Energy balance models, such as Surface Energy Balance Algorithm for Land (SEBAL) and Mapping Evapotranspiration with Internalized Calibration (METRIC). In addition, Penman-Monteith and Priestley-Taylor equations are also used to estimate evapotranspiration. In the case of soil moisture, in general, active (AMSR-E, AMSR2, MIRAS, and SMAP) and passive (ASCAT and SAR)sensors are used for estimation. In terms of statistics, deep learning, as well as linear regression equations and artificial neural networks, are used for estimating these parameters. There were a number of research cases in which various indices were calculated using satellite-based data and applied to the characterization of drought. In some cases, hydrological cycle factors of evapotranspiration and soil moisture were calculated based on the Land Surface Model (LSM). Through this process, by comparing, reviewing, and presenting major detailed methodologies, we intend to use these references in related research, and lay the foundation for the advancement of researches on the calculation of satellite-based hydrological cycle data in the future.

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.
