Athetis dissimilis (Hampson) (Lepidoptera: Noctuidae) [뒷흰날개담색밤나방] was attracted to pheromone traps for Euzophera batangesis (Lepidoprera Pyrimidae) [밤알락명나방], when occurrence of E. batangesis was monitored in sweet persimmon orchard with its pheromone, (Z)-9-tetradecenol (Z9-14OH), (Z9,E12)-9,12-teradecadienol (Z9,E12-14OH) and their mixture. With the components, we monitored the seasonal occurrence of A. dissimilis, tested response of the moth to single or mixed components, and compared efficacy of three different types of traps. A. dissimilis was trapped on May 14 for the first time. First occurrence peak was observed during June 4-24 and second peak during August 20 – September 10. A. dissimilis was attracted to single component of Z9-14OH and Z9,E12-14OH and to their mixture at Jinju, Sancheong, and Sacheon. In trap efficacy tests, delta traps with white color caught most number of the moths significantly at Sacheon. However, at Sancheong, there was no statistical difference among the traps, although funnel trap caught most number of A. dissimilis. Pest status of A. dissimilis is not known eg. whether it is a pest of persimmon or other fruits. However, with Z9-14OH, E9,E12-14OH and their mixture, it is expected to be monitored and controlled.

On the Estimation of Heritability with Family-Based and Population-Based Samples
Kim, Youngdoe,Lee, Young,Lee, Sungyoung,Kim, Nam Hee,Lim, Jeongmin,Kim, Young Jin,Oh, Ji Hee,Min, Haesook,Lee, Meehee,Seo, Hyeon-Jeong,Lee, So-Hyun,Sung, Joohon,Cho, Nam H.,Kim, Bong-Jo,Han, Bok-Ghee Hindawi Publishing Corporation 2015 BioMed research international Vol.2015 No.-
<P>For a family-based sample, the phenotypic variance-covariance matrix can be parameterized to include the variance of a polygenic effect that has then been estimated using a variance component analysis. However, with the advent of large-scale genomic data, the genetic relationship matrix (GRM) can be estimated and can be utilized to parameterize the variance of a polygenic effect for population-based samples. Therefore narrow sense heritability, which is both population and trait specific, can be estimated with both population- and family-based samples. In this study we estimate heritability from both family-based and population-based samples, collected in Korea, and the heritability estimates from the pooled samples were, for height, 0.60; body mass index (BMI), 0.32; log-transformed triglycerides (log TG), 0.24; total cholesterol (TCHL), 0.30; high-density lipoprotein (HDL), 0.38; low-density lipoprotein (LDL), 0.29; systolic blood pressure (SBP), 0.23; and diastolic blood pressure (DBP), 0.24. Furthermore, we found differences in how heritability is estimated—in particular the amount of variance attributable to common environment in twins can be substantial—which indicates heritability estimates should be interpreted with caution.</P>

Effect of Gamma Ray Irradiation on the Development of Drosophila suzukii (Diptera: Drosophilidae)
Jeongmin Kim,Seohae Lee,Junheon Kim,Chung Gyoo Park 한국응용곤충학회 2015 한국응용곤충학회 학술대회논문집 Vol.2015 No.04
Spotted wing drosophila, Drosophila suzukii, native to eastern and southeastern Asia, has become one of the most harmful pests causing serious damage to fruits such as blueberry, cherry, and others in Northern America and Europe. For quarantine sanitary purpose, methyl bromide (MeBr) has been used for a long time. However, it is under regulation because of its adverse effect of ozone layer depletion. Thus, alternative strategies to MeBr are needed to meet the quarantine requirement. In this study, we investigated effects of gamma ray irradiation (0, 50, 100, 200 and 300 Gy) on the development and reproduction of D. suzukii to offer a guideline in using gamma ray for dis-infestation of this pest. The higher doses of gamma ray caused more adverse effects on development and hatchability of D. suzukii. Development and oviposition of D. suzukii was significantly depressed at above certain doses, respective to each developmental stage. When eggs were treated with the doses of gamma ray, eggs hatched in some ratios at all doses. Even though some larvae developed to pupae under 100 Gy irradiation, all these pupae did not emerge to adults at all doses. When larvae were treated with gamma ray, some of them pupated at each doses. However these pupae did not emerge to adults at all under all doses. When pupae were irradiated, the emerged adults did not oviposit eggs above 100 Gy. When adults were irradiated, oviposition occurred normally, but fecundity and hatchability of the eggs were reciprocal to the doses.

<B>ABSTRACT</B><B>Background:</B><P>There is increasing evidence of a relationship between underweight or obesity and dementia risk. Several studies have investigated the relationship between body weight and brain atrophy, a pathological change preceding dementia, but their results are inconsistent. Therefore, we aimed to evaluate the relationship between body mass index (BMI) and cortical atrophy among cognitively normal participants.</P><B>Methods:</B><P>We recruited cognitively normal participants (<I>n</I> = 1,111) who underwent medical checkups and detailed neurologic screening, including magnetic resonance imaging (MRI) in the health screening visits between September 2008 and December 2011. The main outcome was cortical thickness measured using MRI. The number of subjects with five BMI groups in men/women was 9/9, 148/258, 185/128, 149/111, and 64/50 in underweight, normal, overweight, mild obesity, and moderate to severe obesity, respectively. Linear and non-linear relationships between BMI and cortical thickness were examined using multiple linear regression analysis and generalized additive models after adjustment for potential confounders.</P><B>Results:</B><P>Among men, underweight participants showed significant cortical thinning in the frontal and temporal regions compared to normal weight participants, while overweight and mildly obese participants had greater cortical thicknesses in the frontal region and the frontal, temporal, and occipital regions, respectively. However, cortical thickness in each brain region was not significantly different in normal weight and moderate to severe obesity groups. Among women, the association between BMI and cortical thickness was not statistically significant.</P><B>Conclusions:</B><P>Our findings suggested that underweight might be an important risk factor for pathological changes in the brain, while overweight or mild obesity may be inversely associated with cortical atrophy in cognitively normal elderly males.</P>

Effect of Previous Gastrectomy on the Performance of Postoperative Colonoscopy
Kim, Sunghwan,Choi, Jeongmin,Kim, Tae Han,Kong, Seong-Ho,Suh, Yun-Suhk,Im, Jong Pil,Lee, Hyuk-Joon,Kim, Sang Gyun,Jeong, Seung-Yong,Kim, Joo Sung,Yang, Han-Kwang The Korean Gastric Cancer Association 2016 Journal of gastric cancer Vol.16 No.3
Purpose: The purpose of this study was to determine the effect of a prior gastrectomy on the difficulty of subsequent colonoscopy, and to identify the surgical factors related to difficult colonoscopies. Materials and Methods: Patients with a prior gastrectomy who had undergone a colonoscopy between 2011 and 2014 (n=482) were matched (1:6) to patients with no history of gastrectomy (n=2,892). Cecal insertion time, intubation failure, and bowel clearance score were compared between the gastrectomy and control groups, as was a newly generated comprehensive parameter for a difficult/incomplete colonoscopy (cecal intubation failure, cecal insertion time >12.9 minutes, or very poor bowel preparation scale). Surgical factors including surgical approach, extent of gastrectomy, extent of lymph node dissection, and reconstruction type, were analyzed to identify risk factors for colonoscopy performance. Results: A history of gastrectomy was associated with prolonged cecal insertion time ($8.7{\pm}6.4$ vs. $9.7{\pm}6.5$ minutes; P=0.002), an increased intubation failure rate (0.1% vs. 1.9%; P<0.001), and a poor bowel preparation rate (24.7 vs. 29.0; P=0.047). Age and total gastrectomy (vs. partial gastrectomy) were found to be independent risk factors for increased insertion time, which slowly increased throughout the postoperative duration (0.35 min/yr). Total gastrectomy was the only independent risk factor for the comprehensive parameter of difficult/incomplete colonoscopy. Conclusions: History of gastrectomy is related to difficult/incomplete colonoscopy performance, especially in cases of total gastrectomy. In any case, it may be that a pre-operative colonoscopy is desirable in selected patients scheduled for gastrectomy; however, it should be performed by an expert endoscopist each time.

Effect of X-ray Irradiation on Developmental Stages of Drosophila suzukii (Diptera: Drosophilidae)
Jeongmin Kim,Seohae Lee,Junheon Kim,Chung Gyoo Park 한국응용곤충학회 2015 한국응용곤충학회 학술대회논문집 Vol.2015 No.04
Spotted wing drosophila (SWD), Drosophila suzukii, is one of the most harmful pests causing serious damages to blueberries in Northern America and Europe. It is essential to seek alternatives to methyl bromide to ensure dis-infestation of this pest from agricultural products. We investigated the effect of X-ray irradiation (0, 50, 100, 200 and 300 Gy) on development and reproduction of SWD to meet this standard. When eggs were irradiated with the doses, some portion of the eggs hatched even at 300 Gy. The larvae hatched from the irradiated eggs did not pupate at 300 Gy, and they could not develop to adults even at 50 Gy. When larvae were irradiated, they developed up to pupa in some proportion. However above 100 Gy, there was no adult emergence. When pupae were irradiated, some of them emerged to adults. However, the adults could not produce eggs at all above 100 Gy. When adults were irradiated, oviposition occurred normally, but fecundity and hatchability were decreased as irradiation dose went up.

Purpose: This study aimed to analyze the effect of screening by using endoscopy on the diagnosis and treatment of gastric cancer. Materials and Methods: The clinicopathologic characteristics of gastric cancer were compared in individuals who underwent an endoscopy because of symptoms (non-screening group) or for screening purposes (screening group). The distributions of gastric cancer stages and treatment modalities in 2006 and 2011 were compared. Results: The proportion of patients in the screening group increased from 45.1% in 2006 to 65.4% in 2011 (P<0.001). The proportion of stage I cancers in the entire patient sample also increased (from 60.5% in 2006 to 70.6% in 2011; P=0.029). In 2011, the percentages of patients with cancer stages I, II, III, and IV were 79.9%, 8.2%, 10.9%, and 1.1%, respectively, in the screening group, and 47.9%, 10.8%, 29.8%, and 11.5%, respectively, in the non-screening group. The proportion of laparoscopic and robotic surgeries increased from 9.6% in 2006 to 48.3% in 2011 (P<0.001), and endoscopic submucosal dissection increased from 9.8% in 2006 to 19.1% 2011 (P<0.001). Conclusions: The proportion of patients diagnosed with gastric cancer by using the screening program increased between 2006 and 2011. This increase was associated with a high proportion of early-stage cancer diagnoses and increased use of minimally invasive treatments.
