Indicators of environmental conditions qualitatively and quantitatively describe the state of the environment and natural resources, and the OECD (Organization for Economic Cooperation and Development) has initiated and suggested AEIs (Agri-Environmental Indicators) to assess trends over time of the effects of agriculture on the environment and the effectiveness and efficiency of agricultural and environmental policy measures since 1990’s. This study aims to develop the state indicators of water quality for agricultural water, surface and groundwater, to evaluate the environmental impacts of agricultural activities and policies by qualifying the environmental levels of a nation. Status indicators were calculated according to the agricultural water quality standards of OECD and Korea, and their trends were analyzed over time. Particularly, nitrate(NO₃<SUP>-</SUP>) status indicators of ground water in 2013 were significantly lower than the ones in 2000. Overall, the water quality indicators of surface water in 2013 were higher than the ones in 2012, except for pH and DO. The groundwater quality indicators in 2013 were lower than those of previous years. The optimal management indicators were calculated to assess agricultural surface water and groundwater quality. The findings of this study indicated that the state indicators could play a significant role to establish policies and procedures for managing and conserving water resources. This study also discussed water pollution caused by agricultural and industrial effluents.

Aims: We aimed to investigate the association between the change of muscle mass and change of fibrosis and steatosis in NAFLD patients. Methods: We analyzed 2,893 NAFLD subjects who had health check-up more than twice in St. Vincent’s Hospital between November 2009 and December 2017. NAFLD was diagnosed by ultrasound, and appendicular muscle mass (ASM) was assessed by Inbody 720, and Sarcopenia index was calculated as ASM divided by weight (SI%) and ASM divided by body mass index (SI-BMI). Non-invasive markers were used to evaluate the severity of hepatic fibrosis and steatosis; NAFLD fibrosis score (NFS), Fibrosis-4 (Fib-4) score, and Forn’s index for fibrosis, and hepatic steatosis index (HSI) and fatty liver index (FLI) for steatosis. Results: The mean age was 47.3±10.4 years, and 1956 subjects (67.6%) were male. Diabetes, hypertension, metabolic syndrome were more prevalent in sarcopenic subjects (P<0.01), and non-invasive fibrosis and steatosis markers were higher in sarcopenic subjects (P< 0.01). The mean interval between two health check-up was 39.8±21.9 months. There was no significant association between the change of NFS, Fib-4, and Forn’s index and the change of SI% and SI-BMI (all P >0.1). However, the changes of HIS and FLI were significantly associated with the change of SI% and SI-BMI (all P<0.01). Multivariate logistic analysis demonstrated the independent association between the change of skeletal muscle mass and the changes of non-invasive steatosis markers after adjusting for other confounding factors (all P< 0.001). However, the changes of non-invasive fibrosis markers did not show an independent association with the change of appendicular muscle mass after adjusting for other confounders (all P >0.1) Conclusions: The change of muscle mass is strongly associated with the change of hepatic steatosis, but not the change of fibrosis.

We assessed the safety and biotechnological properties of 17 Enterococcus faecalis and 18 Enterococcus faecium strains isolated from Meju to select starter candidates for quality Meju production. Minimum inhibitory concentration assays showed that all strains were susceptible to ampicillin, chloramphenicol, ciprofloxacin, erythromycin, gentamicin, penicillin G, and tetracycline, as judged by the breakpoint values defined at the species level by the European Committee on Antimicrobial Susceptibility Testing, whereas two E. faecalis strains were resistant to vancomycin, which could be ascribed to acquired resistance. None of the strains exhibited ${\alpha}$- or ${\beta}$-hemolytic activities or biofilm formation. Both species showed similar levels of biogenic amine production, and noticeable amounts of tyramine ($3397.4{\pm}172.4ppm$) were produced by all strains in the presence of precursors (histidine, lysine, ornithine, and tyrosine). All strains exhibited protease, lipase, and acid production, with decreased activity observed with increasing NaCl concentrations. This study confirmed the necessity of antibiotic resistance screening of Enterococcus species for food production, with the identification of vancomycin-resistant strains from Meju.

But there has not been any report on the clinical characteristics of herpes zoster in the Province of Gyeongsangnam-do. Objectives: The purpose of this study was the elucidation of the clinical characteristics of herpes zoster in the Province of Gyeongsangnam-do. Methods: The study was conducted between 2011 and 2015 at our hospital outpatients. 901 patients with herpes zoster were evaluated in regard to age, sex, dermatomic distributions, associated diseases and complications. Results: Out of 901 cases, 396 were males and 505 were females. The maximum incidence was in the over 70 year-old group (26.4%). The most frequent involved dermatome was the trigeminal dermatome (28.7%). Associated diseases were observed in 679 patients (75.3%), which included hypertension (21.2%), malignancy (11.4%) and so on. Out of 901 patients, 443 (49.2%) developed complications. The most common complication was postherpetic neuralgia (27.1%). It is noteworthy that skin edema was accompanied from 43 patients (4.8%). Fourty patients showed edematous change on herpes zoster lesion. But other 3 patients showed facial edema in spite of involving herpes zoster in other area. Conclusion: Most of the results are similar to those previously reported, except for a higher incidence in trigeminal dermatome. The most interesting part of this study is herpes zoster can cause skin edema. We need to take further studies in future by others to explain causes in detail.
Prurigo nodularis with HIV-infected patient
( Jeong Won Jo ),( Hae Bong Jeong ),( Yun Sun Moon ),( Do Seon Jeong ),( Eui Chang Jung ),( Chi Yeon Kim ),( Tae Jin Yoon ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1
Prurigo nodularis (PN) is a chronic dermatosis of unknown etiology characterized by discrete, intensely pruritic, symmetric, papulonodular lesions primarily on the extensor surfaces of the extremities. It is commonly seen in persons infected with human immunodeficiency virus (HIV) and with low CD4 counts. The pathophysiology of prurigo nodularis in the HIV infected population is particularly interesting and has not been investigated thoroughly. Prurigo nodularis is usually associated with HIV because it is easy to diagnose prurigo nodularis in HIV patients. However, it is difficult to diagnose HIV infection in a patient prurigo nodularis. We herein, report a case in confirming the HIV infection diagnosed with prurigo nodularis.
[P336] Generalized cutaneous angiosarcoma associated with multiple myeloma
( Jeong Won Jo ),( Young Bin Shin ),( Hae Bong Jeong ),( Yun Sun Moon ),( Do Seon Jeong ),( Eui Chang Jung ),( Chi Yeon Kim ),( Tae Jin Yoon ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1
Cutaneous angiosarcoma is a rare, malignant, vascular neoplasm of the skin commonly diagnosed in the head and neck regions. It arises infrequently in the lower extremity. In most cases, the exact etiology of cutaneous angiosarcoma is unclear. Recently, gene amplifications, especially MYC gene, have been identified as a new etiopathogenesis of angiosarcoma. MYC amplification may induce aberrant angiogenic phenotypes allowing the onset of the malignancy. Meanwhile, in multiple myeloma, MYC is activated and contributes to the malignant phenotype. Therefore, there is a possibility that MYC gene might be the common cause of angiosarcoma and multiple myeloma. Herein, we present the rare case of cutaneous angiosarcoma on lower extremity accompanied by multiple myeloma. An 85-year-old woman visited our department with multiple brownish to black colored nodules with hyperkeratotic crust, which were 0.3 to 0.8 cm in diameter, on the both feet and toes. The excisional biopsy was performed and a diagnosis of cutaneous angiosarcoma was made. At the time of visit, anemia, azotemia, proteinuria and hematuria were found. Immunofixation electrophoresis and bone marrow were performed, so multiple myeloma was diagnosed. We suspected carefully that MYC gene might be the common cause of angiosarcoma and multiple myeloma.
