Estimating population density of Nicrophorus quadripunctatus (Coleoptera: Silphidae) in Korea
Kim Do‐Sung,Cho Young‐Bok,Han Yong‐Gu 한국곤충학회 2020 Entomological Research Vol.50 No.11
Estimating the population density of organisms is of great concern to ecologists and much effort has been put into making accurate assessment of population levels in nature. We evaluated the trapping web (TW) method for the determination of the density of species of burying beetles. We found eight and six species of burying beetles at Beopjusa and Ssanggok‐ri areas, respectively. Most of the species population comprised Nicrophorus quadripunctatus, with densities of 65 and 195 per ha for Beopjusa and Ssanggok‐ri areas, respectively. Moreover, the flight intercept trap (FIT) method from 2003 to 2007 also revealed the same trend: Beopjusa temple (2928) to Ssanggok‐ri (5835). However, the differences in number of individuals were probably due to the differences in the methods and the length of the trapping period. The populations of N. quadripunctatus exist as metapopulations, making accurate assessment of the population densities extremely difficult. We hypothesized that the TW method could accurately estimate population densities extrapolated from patch population size per area.

S-60 A Rare Case of Cholecystogastric Fistula Developed in a Patient with Early Gastric Cancer
( Do Il Choi ),( Keun Won Ryu ),( Sang Jae Park ),( Soo-jeong Cho ) 대한내과학회 2016 대한내과학회 추계학술발표논문집 Vol.2016 No.1
Cholecystoenteric fistulas, including cholecystogastric, cholecystoduodenal, and cholecystocolonic ones, are the rare complications of long-standing cholelithiasis. In terms of cholecystogastric type, there are only a few reports worldwide. A 55-year-old woman initially visited a local clinic due to intermittent epigastric soreness. She underwent esophagogastroduodenoscopy (EGD) and was diagnosed with early gastric cancer (EGC) based on forceps biopsy revealing tubular adenocarcinoma. She was referred to our hospital for the management of EGC. When she visited to our clinic, she had no fever and abdominal pain. Physical examination and laboratory findings were unremarkable. EGD revealed EGC at the mid-body lesser curvature side and subepithelial mass with central ulcer-like lesion at the antrum greater curvature side. From the ulcer, pus-like discharge was draining repetitively. Culture study for the discharge confirmed that there were Escherichia coli, Klebsiella pneumonia, and Streptococcus sanquis. Abdominal computed tomography scan showed that she had a chronic calculous cholecystitis and a passed gallstone through cholecystogastric fistula. She was treated with ciprofloxacin medication, and underwent radical subtotal gastrectomy and cholecystectomy. To the best of our knowledge, this report describes very rare case of cholecystogastric fistula developed in a patient with EGC and chronic calculous cholecystitis.

The composition of the deicer sprayed on the highway is spreading over the highway by the scattering or snow removal activity, or car movement and consequently affecting the vegetation environment around the highway. These are the cause of the damage of fruit trees and crops, and also the cause of corrosion of highway structures. The goal of this study is to estimate the detected range of deicer components from a highway. The concentration of the deicer components in gauze and soil were investigated according to the crossing distance from the highway. The data collected were then used to estimate the concentration range of deicer components in a rage of distance up to 100 m from the highway where the deicer was spread. The sample time and weight of gauze were measured before and after installation, and the soil was collected at more than three points in parallel with the highway at the gauze installation point. The components in gauze and soil were investigated in addition to the deicer components (Ca2+, Na+, Cl-) as well as Mg2+ and K+. As Ca2+ and Cl- components of deicer were affected by agricultural use, Na+ component was selected as a tracer and further SAR (Sodium Adsorption Ratio) of soil was analyzed to examine the degree of influence on vegetation indirectly. The gauze concentration was evaluated by the concentration of the deicer ingredient at the background concentration of the blank gauze. The total amount of the deicer sprayed in the study road for 4 months (winter season) was about 93 ton/km. In the gauze test, the spread of the deicer was detected at a distance of 100 m in study area, but the concentration of the deicer in the gauze by distance decreased rapidly within 10 m from the highway. And concentration of the deicer components in gauze and soil came down after rainy season (August ~ Sep.). The results showed that the components of the deicer could be spread widely by the wind. The effective range of the deicer on vegetation based on SAR in soil was estimated to be less than 20 m from the highway. This study examines the concentration changes of the deicer components in gauze and soils and shows that deicer components sprayed on the highway are accumulated and moved over time by wind, snow removal, terrain, water system and land use around the highway.

Purpose: Sudden cardiac arrest (SCA) accounts for approximately 15% of all-cause mortality in the US and 50% of all cardiovascular mortalities in developed countries; 10% of cases have an underlying structural cardiac abnormality. An echocardiography has widely been used to evaluate cardiac abnormality, but it needs to be performed by emergency physicians available in the emergency department immediately after death, rather than by cardiologists. We aimed to determine whether post-mortem echocardiography (PME) performed in the emergency department may reveal such abnormalities. Methods: We evaluated the reliability and validity of PME performed by emergency physicians in the emergency department. Measurement by a cardiologist was used as reference. Results: Two emergency physicians performed PME on 3 out of the 4 included patients who died after unsuccessful cardiopulmonary resuscitation. PME was started within 10 minutes of death, and it took 10 minutes to complete. Parasternal views in either supine or left decubitus position were most helpful. The adequacy of the image was rated good to fair, and that of measurements was acceptable to borderline. Regarding the chamber size and left ventricular wall thickness, intraclass correlation coefficients for reliability and validity were 0.97 (n=15) and 0.95 (n=35), respectively (p<0.001). Evaluation of presence/absence of left ventricular wall thinning, valve calcification, and pericardial effusion was incomplete (3/7-5/7), precluding further analysis. Conclusion: Emergency physicians could perform reliable and valid PME to assess the chamber size and left ventricular wall thickness. A large prospective study with collaboration between emergency physicians and cardiologists would reveal the feasibility and usefulness of PME in diagnosing structural causes of sudden cardiac arrest.

Backgrounds/Aims: Pancreaticoduodenectomy (PD) is a standard surgical procedure for patients with periampullary cancer. During the follow-up period after PD, recurrence can be observed in various places with different prognosis. The aim of this study was to clarify the pattern of recurrence and factors affecting the survival of patients with periampullary cancer. Methods: Overall, 88 patients who received PD for distal common bile duct cancer or ampulla of Vater cancer were finally included and their clinical characteristics were analyzed. Patients were divided into three groups: recurrence-free (RF) group, an isolated locoregional recurrence (LR) group, and a distant metastasis (DM) group. Prognostic factors affecting recurrence in each group were analyzed and a survival analysis was performed. Results: Perineural invasion (PNI), T stage, and lymphovascular invasion (LVI) were significant risk factors for LR and PNI, lymph node metastasis, LVI, and T stage were associated with DM group compared to RF group in univariate analysis, respectively. N stage and PNI were significant risk factors (p = 0.046, p = 0.041) in overall survival of the LR and the DM groups. There was no significant difference in 5-year overall survival between the LR and DM groups. Conclusions: T stage was a significant risk factor of LR, while PNI was a significant risk factor of DM. There was no significant difference in overall survival depending on the site of recurrence.
