Objective: Ultrasonographic screening between 9 and 13 weeks for fetal structural abnormalities using transvaginal sonography in unselected population. Visualization of detailed fetal anatomy in the first trimester has improved as a result of technological progress in ultrasound machines and the introduction of transvaginal sonography(TVS). Our study aims to evaluate the accuracy of TVS as a screening tool for detecting fetal malformations in a nonselected population of pregnant women. For this purpose we compared the results obtained by using second trimesster TA scanning with those obtained using TVS at 9-14 weeks' gestation. Methods: From March 2001 to February 2003, 620 unselected consecutive pregnant women were recruited at their initial visit at Soonchunhyang university hospital, department of obstetrics and gynecology and offered a TVS scan at the average gestational age of 9-13 weeks in addition to the TA screening usually performed between 22-26 weeks. To fulfill the technical requirements of a screening test, ultrasonographic examinations were performed by skillful operators with different degrees of experienced using adequate instruments Aloka SSD 5500 (Aloka Co. Ltd., Tokyo, Japan) provided with either a 3.5-5MHz TA probe or a 5-7.5MHZ TV probe) in a fixed scanning time of maximum 30 min, generally considered sufficient for a complete fetal anatomic survey. Results: During the study period we found in our unselected population an overall prevalence of target abnormalities of 2.2%(24 malformed fetuses out of 600 screened). In the fetuses examined by TVS, 16 abnormalities were detected whereas 8 were not; of these, 6 were detected at transabdominal rescreening at 22-26 weeks and the remaining 2 were observed after birth. A nuchal region abnormality was the most frequent type of malformation detected in the early scan, including six cases of nuchal edema, two cases of cystic hygroma associated with hygroma associated with hydrops, three cases of hydronephrosis, one case of fetal neck teratoma, one case of cleft lip. Conclusion: This study has demonstrated the potential of screening a low risk population for fetal abnormalities at 9-13 weeks of gestation using transvaginal sonography and rescreened via transabdominal sonography at 22-26 weeks. Larger studies are required to establish the clinical value of the first trimester scan.

Background : About 30% of patients in the hospital are under nourishment. A large portion of people are undernourished when they are admitted to the hospital and in the majority of these, undernutrition develops further while in hospital. Patient-Generated subjective global assessment(PG-SGA), a method of nutritional assessment based on clinical judgment, has been widely used to assess the nutritional status of adults for both clinical and research purposes. Modified PG-SGA can be used as a nutrition screening tool, and a comprehensive nutrition assessment is desirable for those who are malnourished. The purpose of this study is to develop a simple, reliable and valid nutrition screening program(NSP). Methods : We applied the nutrition screening program(NSP) to adult inpatients who are at risk of malnutrition using the Modified Patient-Generated subjective global assessment(PG-SGA) and objective assessment(electrical medical record data). Results : Therefore simple and beneficial NSP is developed for patients with severe malnutrition. Using NSP. nutritional information of the severe malnutrition patient should be shared with the physicians and they should be taken care of by clinical dietitians to improve their nutritional status. Conclusion : The Modified PG-SGA and nutrition screening tool are simple, reliable and valid nutrition screening program(NSP).

This studies was conducted to define community structure and diversity of epigeal spiders in apple orchards under different farming practices (organic and conventional). In 11 commercial apple orchards, epigeal spider community structure was investigated during 2012-2014 (3 orchards, 2012; 3 orchards, 2013, 5 orchards, 2014). Epigeal spiders were collected by pitfall traps from April to October, 2012 in Danyang-gun, Chungcheongbuk-do; 2013 in Muju-gun, Jeollabuk-do; 2014 in Cheongsong-gun and Uiseong-gun, Gyeongsangbuk-do, Korea. Sampled spiders were identified to the species level. Biodiversity was analyzed with species richness (total numbers of spider species), abundance (total numbers of individuals) and Shannon-Wiener diversity index (H΄) for each site and compared between organic and conventional orchards. In all regions, abundance of the spider communities were relatively higher in organic orchards than in conventional orchards. But, no significant difference in species richness and specie diversity (H΄) between organic and conventional orchards. Lycosidae was the most dominant family in all orchards regardless farming practices. However, Linyphiidae dominated in organic orchards only. The most dominant species were Pardosa laura (Lycosidae), Erigone koshiensis (Linyphiidae) in organic, Piratula procurvus (Lycosidae) in conventional orchards.

Epigeic spiders (Araneae) were surveyed in apple orchards under different farming practices (organic and conventional) in Muju-gun, Jeollabuk-do, Korea. The study was conducted from April to October in 2013 with 2 weeks interval using pitfall traps. Collected spiders were identified as 20 species of 6 families from 819 individuals in organic orchardⅠ, 19 species of 10 families from 759 individuals in orchardⅡ and 16 species of 8 families from 209 individuals in conventional orchard for from 1,787 captured spiders. Biodiversity was analyzed with species richness, abundance and Shannon diversity index (H΄). Species richness was statistically higher in organic orchard than in conventional orchard. Organic orchardⅡ comprised the greatest abundance followed by organic orchard and conventional. But species diversity was the highest in organic orchardⅡ, intermediate in conventional orchard and the lowest in orchardⅠ. Lycosidae was the most dominant family in all orchards regardless farming practices. However, Linyphiidae dominated in organic orchards only. The most dominant species were Erigone koshiensis (Linyphiidae) in organicⅠ, Pardosa laura (Lycosidae) in organicⅡ and Arctosa pungcheunensis (Lycosidae) in conventional orchard.

In apple orchards under different farming practices (organic and conventional), arthropod community structure was investigated. Arthropods were collected with pitfall traps, band traps, yellow sticky traps and pheromone traps from May to December, 2012 in Danyang-gun, Chungcheongbuk-do, Korea. Biodiversity was analyzed with species richness and Shannon diversity index (H΄). Sampled arthropods were identified 37 families in 14 orders from 21,618 individuals in organic orchard-1 and 33 families in 10 orders from 11,318 individuals in organic orchard-2 and 35 families in 13 orders from 27,711 individuals in conventional orchard. Species richness was relatively highest in organic orchard-1, intermediate in conventional orchard and lowest in organic orchard-2. In ecologically functional group, abundance of pests was higher in conventional orchard than in organic orchards due to the high occurrence of Phyllonorycte ringoniella (Gracillariidae) and Lyonetia prunifoliella (Lyonetiidae). Organic orchards showed higher abundance, species richness and species diversity of epigeic predators and those of parasitoids above ground than conventional orchard. Abundance of detritivores, mainly collembola, were higher in organic orchard than in conventional orchard.

Spider fauna of Mt. Yongmunsan located in Yangpyeong-gun, Gyeonggi-do, was surveyed from April to October in 1996. A total of 75 species of 51 genera in 22 families from 996 individuals of spiders were identified. Species richness of each family, there were 17 Araneid species (22.7%), followed by each of the 7 Thomisid and Tetragnathid species (9.3%), 6 Salticid species (8.0%), and 5 Lycosid species (6.7%). Zoogeographically, spider fauna of Mt. Yongmunsan represented 1 cosmopolitan species (1.3%), 2 holarctic region species (2.6%), and 9 palearctic region species (12.0%), and 4 Korean endemic species (4.0%). Thus it is suggested that spider fauna of Mt. Yongmunsan was under northern regional influence.
