The leafhopper subfamily, Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae), caused direct damage by sap-sucking or indirect damage by transmission of viruses or diseases to the host plants, so Typhlocybinae is one of the most important insect pests in agriculture, urban ecology, forest, etc. in the world. However, their identifications are very difficult due to small size and morphological similarities, and their exact biological information such as host plants and life cycle are not reported yet for most species. So, we construct an integrated biological database that presents accurate diagnostic methods (illustrated key characters, DNA barcoding data), patterns and seasons of occurrences, and some ecological photographs such as dorsal habitus of specimens and plant damages

Grapevines are cultivated globally, and are also damaged by a large number of insect pests especially including leafhoppers. Leafhoppers are one of the important insect pests on various crops including grape. Among them, the genus Arboridia Zachvatkin (Hemiptera: Auchenorrhyncha: Cicadellidae: Typhlocybinae) was known as insect pests against grape farming. Eighty species were described in the genus in the world, and eight species were recorded in the Korean Peninsula so far, which are: Arboridia apicalis, A. kakogawana, A. koreacola, A. maculifrons, A. nigrigena, A. okamotonis, A. silvarum, A. suzukii. Among them, A. apicalis, A. kakogawana, A. maculifrons, A. nigrigena, A. suzukii have been known as important insect pests on grapes. In this talk, we propose a new species from the Korean Peninsula, and confirmed two new records: A. agrillacea and A. lunula. Additionally we present differential diagnoses of the Arboridia species damaging on grapevines for the field of applied biology.

The genus Arboridia Zachvatkin belongs to the tribe Erythroneurini of the subfamily Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae). A total of 69 valid species have been described in the Palaearctic and Oriental region. So far, seven species of this genus have been recorded in the Korean Peninsula. In this study, we present two new species, Arboridia sp. nov. 1, Arboridia sp. nov. 2, and provide a key to the Arboridia species in the Korean Peninsula with biological information such as host plants and distributions.

Gastritis is a major disease that has the potential to grow as gastric cancer. Gastric cancer is a very common cancer, and it is related to a very high mortality rate in Korea. This disease is known to have various reasons, including infection with Helicobacter pylori, dietary habits, tobacco, and alcohol. The incidence rate of gastritis has reported to differ between age, population, and gender. However, unlike other factors, there has been no analysis based on gender. So, we examined the high risk factors of gastritis in each gender in the Korean population by focusing on sex. We performed an analysis of 120 clinical characteristics and genome-wide association studies (GWAS) using 349,184 single-nucleotide polymorphisms from the results of Anseong and Ansan cohort study in the Korea Association Resource (KARE) project. As the result, we could not prove a strong relation with these factors and gastritis or gastric ulcer in the GWAS. However, we confirmed several already-known risk factors and also found some differences of clinical characteristics in each gender using logistic regression. As a result of the logistic regression, a relation with hyperlipidemia, coronary artery disease, myocardial infarction, hyperlipidemia therapy, hypotensive or antihypotensive drug, diastolic blood pressure, and gastritis was seen in males; the results of this study suggest that vascular disease has a potential association with gastritis in males.

Objective This study aimed to compare perioperative and postoperative morbidity of older and younger women undergoing sacrocolpopexy (SCP). Methods A retrospective study included 271 patients who underwent laparotomic SCP for symptomatic pelvic organ prolapse from November 2008 to June 2013 at our institution. By the review of medical records, perioperative and postoperative data including the length of the surgery, estimated blood loss, blood transfusion, the length of hospital stay, wound complications and febrile morbidity were collected. In addition, cardiovascular, pulmonary, gastrointestinal, genitourinary,or neurological adverse events were retrieved. The need for an indwelling urinary catheter or performance of clean intermittent self-catheterization, mesh erosion rate and the number of days required for each were included in the postoperative outcomes. For the outcome variable analyzed in this study, the patients was dichomotized into women aged 65 and older and those younger than 65. Results One hundred and thirty-five (49.8%) patients were younger than 65 and 136 (50.2%) were aged 65 and older. Older women had higher body mass index, vaginal parity and prior surgery for hysterectomy than younger women (P<0.05). And older women had higher baseline comorbidities, such as hypertension, diabetes, cardiac disease (P<0.05), and theirAmerican society of Anesthesiologist class was higher (P<0.001). In the perioperative and postoperative complication, older group showed no differences in most of the operation-related complication rates, but gastrointestinal complication rate. Also, mesh erosion rate was not found to be significantly different between the two groups at the last visit. Conclusion Older women undergoing laparotomic SCP have similar perioperative and postoperative morbidities as younger women, suggesting surgeons can counsel older and younger women similarly in terms of operative risks.

The leafhopper family Cicadellidae (Hemiptera: Auchenorrhyncha) is plant feeders, with mouthparts adapted for sucking. Almost of the them cause injuries of destruction to plants, including fruit trees and grain crops, and can be vectors of plant diseases. Therefor, Cicadellidae is one of the most important pests in the world. However, their identifications are very difficult because of small size and morphological similarities, and their exact biological information such as host plants, life cycle and distribution are not clear for most species. So, we provide and integrated biological database that present accurate diagnostic methods and ecological infromation.

Leafhopper subfamily, Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae), caused direct damage by sap-sucking or indirect damage by transmission of viruses or diseases on the host plants, so typhlocybinae is one of the important pest groups in the world. Typhlocybinae distribute worldwide and a total of 471 genera and more than 4,300 species have been described. so far, 38 genera and 102 species were recorded in the Korean Peninsula. In this talk, we provide several taxonomic studies for the Korean typhlocybene fauna based on the genus-level reviews of the subfamily from the Korean Peninsula.
