This study aims to find a recycling method for agricultural reservoirs that have lost or deteriorated as agricultural reservoirs. The method of research is to define functional reservoirs for agriculture through preceding studies, case studies, current status surveys, and surveys, and to derive usage plans for each type. The problems of functional loss agricultural reservoirs were found in economic/industrial, safety, developmental, and socio-cultural aspects in previous studies. As a result of the survey, damage to the urban landscape emerged as the biggest problem. Through previous studies and case studies, it was identified that type of hydrophilicity, leisure type, energy development type, types of historical and cultural resources linkage, ecological learning type, etc. are being used. The need for utilization measures has been raised. In order to suggest usage plans for each type, five types were classified based on the size of the agricultural reservoir, the surrounding population, and the presence or absence of ecological and natural and historical resources of the adjacent area. As a result of classification, it was found that the ecological learning type, type C, took up the largest proportion with 10 sites, and the type D, types of historical and cultural resources linkage, occupies the smallest proportion. The result is meaningful in that it defines and classifies the types of loss-of-function agricultural reservoirs in the southern Gyeonggi region, and suggests usage plans for each type.

Psychological and social disturbances can be caused by gynecomastia and nipple hypertrophy. Several corrections for these problems have been developed. Recently, social trends focus on a good body shape. Young male patients increasingly visit hospitals to correction of minor deformities of breasts. These patients don't visit the hospital for just one of pathologic problem but seek corrections for multiple problems. These problems are mild forms of gynecomastia, nipple hypertrophy and areolar hypertrophy. Ten patients have visited our hospital to correct various problems using multiple procedures. Liposuction was used to reduce breast tissue in gynecomastia. Protruding of areola was corrected by intra-areola or circum-areola parenchymal excision. Large areolas were reduced by intra-areola circular incision. Large nipples were reduced by Regnault tehnique or wedge resection. We conclude that new trends of male breast correction is to watch nipple-areola-breast as one complex. A combined procedures must be done for correction of these trends.

Purpose : To determine the efficacy of correction of a malfunctioning peritoneal dialysis catheter withguidewire and stiffener under fluoroscopic guidance. Materials and Method : Between November 1994 and March 1997,we performed 15 manipulations in 12 patients in whom a dual-cuff, straight Tenckhoff peritoneal dialysis catheterhad been implanted due to chronic renal failure. The causes of catheter malfunctioning were inadequate drainage ofthe dialysate(n=14) and painful dialysis(n=1). Under fluoroscopic guidance, adhesiolysis and repositioning of themalfunctioning catheter were performed with an Amplatz Super Stiff guidewire and the stiffener from a biliarydrainage catheter. The results of procedures were categorized as either immediate or durable success, this latterbeing defined as adequate catheter function for at least one month after the procedure. Results : Immediatesuccess was achieved in 14 of 15 procedures (93%), and durable success in 7 of 15 (47%). The mean duration ofcatheter function was 157 (range, 30 to 578) days. After manipulation, abdominal pain developed in eight patientsand peritonitis in two, but with conservative treatment, these symptoms improved. Conclusion : The correction of amalfunctioning peritoneal dialysis catheter with guidewire and stiffener under fluoroscopic guidance is aneffective means of restoring catheter function and may be an effective alternative to surgical reimplantation ofthe catheter, or hemodialysis.

About 70% of activating EGFRm can be detected using CtDNA in patients with activating EGFRm in their Tumor DNA. The treatment efficacy of afatinib was assessed in patients with lung cancer harboring EGFRm which were detected from CtDNA. Primary objective was to prove overall response rate (ORR) in response evaluable population, and the secondary endpoints were progression free survival, overall survival and safety. Ten mL of venous blood was withdrawn and plasma preparation was finished as soon as possible, no more than 4 hours after draw. Plasma samples were stored at -20℃ until delivered to Panagene. EGFRm analyses for CtDNA were performed by PANA Mutyper® EGFR kit (Panagene, Korea). EGFRm testing for tumor DNA were performed by in-house testing in each hospital with PNA clamp EGFR mutation kit or PANA Mutyper® EGFR kit. A total of 340 (331 without missing values) patients were screened for this trial from 2015 July to 2018 March. Tumor genotyping showed 24.5% (81/331), while CtDNA showed 20.5% (68/331) of positivity to detect activating EGFRm (exon 19 deletions, exon 21 and exon 18 point mutations). Among 81 subjects with tumor DNA EGFRm positive subjects, 48 showed EGFRm in their CtDNA (59% sensitivity). Types of EGFRm were completely matched between tumor DNA and CtDNA in 48 subjects. Among 21 subjects enrolled in this trial, 11 subjects had EGFRm only in CtDNA (tumor DNA EGFR wild or unknown, Group 1), and 10 subjects had same EGFRm in their CtDNA and tumor DNA (Group 2). Afatinib (40mg) was initiated in 21 (female:17, adenocarcinoma:20, NSCLC-NOS:1) subjects with mean age of 68.5 years (standard deviation 8.7). Dose modifications were made in 13 subjects (62%). Partial remission was observed in 13 subjects, stable disease in 6 subjects, and response was not evaluated in 2 subjects (ORR : 68.4%). There was no significant difference (p=0.35) in ORR between Group 1 (80%) and Group 2 (55.6%). As of July 25 2018, treatment is ongoing in 15 subjects, progression was confirmed in 3 subjects and 1 withdrew consent, 2 discontinued treatment due to serious adverse events (SAEs). A total of 5 SAEs including 2 subjects with possible drug induced lung disease were reported. In conclusion, afatinib showed favorable efficacy in subjects with NSCLC harboring EGFRm in their CtDNA.
