The membranous bone is new used frequently to fill the defect made during the craniofacial osteotmy. The membranous bone is resolved less than the endochondral bone after the free graft, and maintains its greater preportion when it is transfered with its vascular pedicle. It is also known that there is less resorption in the orthotopic graft than in the heterotopic graft. We have stuided the amount of resorption of the orthotopically grafted bone in the vascularized and nonvascularized model. A zygomatic arch of the rabbit was resected completely and was fixed orthotopically using a wire. The contralateral one was resected and fixed with its muscle attachment(masseter). After 8 weeks the animals were sacrificed. The volume of the grafted bone was compared. There 10±2% volume loss in the vascularized modol and 18±4% volume loss in the free graft model with a statistically significant difference(P<0.001). Histologically, in the vascularized graft, primary bony union was observed and the original architecture was preserved well and the periosteal activity way great. The free graft was also healed by bony union except in 1 case. But the architectural irregularity was more prominent in the free graft than in the vascularized graft.

본 연구의 목적은 사회복지조직의 공개 채용공고가 실제채용기준을 얼마나 반영하고 있는지 파악하여 채용공고의 변화가능성을 탐색하기 위함이다. 이러한 목적을 달성하기 위해 2008년 한국사회복지사협회의 채용공고 중 210건의 조직을 표집하여 기초분석을 통해 정보내용을 파악하였고, 서울과 대전의 23개 조직의 기관장을 대상으로 1:1면접을 통해 사례연구를 진행하였다. 분석결과, 실제채용기준은 자원봉사와 실습을 통한 현장경험, 사회복지사 1급 자격증, 지원자와 조직의 비전 일치, 사회복지 마인드, 대인관계 등으로 드러났다. 그러나 이는 채용공고에 제시되지 않거나 질적인 차이를 보였다. The purpose of this study is to understand how an open employment notice has reflected the actual criterions of the recruitment, and to discover a potential for any changes. To achieve this purpose, a systematic random sample of 210 open employment notices was selected from Korea Association of Social Workers in 2008, and a descriptive analysis was conducted. The qualitative research was carried out for the case study with 23 interviewees from social welfare organizations in Seoul and Daejeon. Consequently, the actual criterions of the recruitment included the following elements: social work field practicum and volunteer work, the level one social welfare license, degree of harmony with the vision of the organization, dept of social welfare-oriented mind, and human networks. However, these criterions may not be presented in open employment notices or show that there are qualitative differences between open employment notices and the actual employment criterions.

Purpose: Chest radiography is often performed on patients hospitalized with typical clinical manifestations of bronchiolitis. We aimed to determine the proportion of subjects with pathologic chest radiographic findings and the clinical predictors associated with pathologic chest radiographic findings in young children admitted with the typical presentation of bronchiolitis. Methods: We obtained the following data at admission: sex, age, neonatal history, past history of hospitalization for respiratory illnesses, heart rate, respiratory rate, the presence of fever, total duration of fever, oxygen saturation, laboratory parameters (i.e., complete blood cell count, high-sensitivity C-reactive protein [hs-CRP], etc.), and chest radiography. Results: The study comprised 279 young children. Of these, 26 had a chest radiograph revealing opacity (n=24) or atelectasis (n=2). Multivariate logistic regression analysis showed that after adjustment for confounding factors, the clinical predictors associated with pathologic chest radiographic findings in young children admitted with bronchiolitis were elevated hs-CRP level (>0.3 mg/dL) and past history of hospitalization for respiratory illnesses (all P<0.05). Conclusion: The current study suggests that chest radiographs in young children with typical clinical manifestations of bronchiolitis have limited value. Nonetheless, young children with clinical factors such as high hs-CRP levels at admission or past history of hospitalization for respiratory illnesses may be more likely to have pathologic chest radiographic findings.

Differential Morphological, Structural and Biological Characteristics of Cysts in Heterodera Species in Korea

Ga Ram Han,Heonil Kang,In Soo Choi,Donggeun Kim,Hye Young Yun,Young Ho Kim 한국식물병리학회 2020 Plant Pathology Journal Vol.36 No.6

Morphological (cyst shape, color, and sizes [length (L), maximum width (W), volume and “a” (L/W)]), structural (vulvar cone slope angle [VCSA], surface wrinkle [VCSW], cyst wall thickness, composition, and texture) and biological characteristics (fecundity, hatching, and emergence [number of second-stage juveniles (J2) from a cyst]) in preceding Heterodera glycines (Hg), currently- recorded H. sojae (Hs) and H. trifolii (Ht) were examined by microscopy. Cysts were lemon-shaped, indicating the genus is Heterodera except for Hs that formed frequently globular cysts with significantly flatter VCSA (102.2°) with smooth VCSW than Hg (50.6°) and Ht (82.0°), but not genus Globodera because of the presence of vulvar cone in Hs. Ht was significantly larger in all morphological characteristics than Hg and Hs, suggesting Ht may be diagnosed differentially by cyst sizes and also host plant preferences. Hs showed smaller “a” value with more globular shape and stronger structures with more thickened and strengthened collagen-like texture of cyst wall than Hg and Ht. This suggests Hs may be diagnosed differently by structural characteristics from the others, especially Hg with similar cyst sizes. There were no significant differences in emergence (inoculum potential) among cyst nematodes due to the offset of fecundity and hatching rate; however, the inoculum potential of Hs may be not so persistent as Hg and Ht in fields because of its lower fecundity and higher hatching rate (causing rapid inoculum loss) than the others. These characteristics of cysts provide information useful for simple and differential diagnoses and reliable management of cyst nematodes.

Betaine supplementation has been shown to alleviate altered glucose and lipid metabolism in mice fed a high-fat diet or a high-sucrose diet. We investigated the beneficial effects of betaine in diabetic db/db mice. Alleviation of endoplasmic reticulum (ER) and oxidative stress was also examined in the livers and brains of db/db mice fed a betaine-supplemented diet. Male C57BL/KsJ-db/db mice were fed with or without 1% betaine for 5 wk (referred to as the db/db-betaine group and the db/db group, respectively). Lean non-diabetic db/+ mice were used as the control group. Betaine supplementation significantly alleviated hyperinsulinemia in db/db mice. Betaine reduced hepatic expression of peroxisome proliferator-activated receptor gamma coactivator 1 alpha, a major transcription factor involved in gluconeogenesis. Lower serum triglyceride concentrations were also observed in the db/db-betaine group compared to the db/db group. Betaine supplementation induced hepatic peroxisome proliferator-activated receptor alpha and carnitine palmitoyltransferase 1a mRNA levels, and reduced acetyl-CoA carboxylase activity. Mice fed a betaine-supplemented diet had increased total glutathione concentrations and catalase activity, and reduced lipid peroxidation levels in the liver. Furthermore, betaine also reduced ER stress in liver and brain. c-Jun N-terminal kinase activity and tau hyperphosphorylation levels were lower in db/db mice fed a betaine-supplemented diet, compared to db/db mice. Our findings suggest that betaine improves hyperlipidemia and tau hyperphosphorylation in db/db mice with insulin resistance by alleviating ER and oxidative stress.

( Ga Won Song ),( Sun Young Shin ),( Kyu Hyun Han ),( Suk Pyo Shin ),( Seong Gyu Hwang ),( Kyu Sung Rim ),( Hana Park ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background/Aim: Transarterial chemoembolization (TACE) is one of the locolesional treatment modalities for hepatocellular carcinoma (HCC). However, disease progression after TACE is often developed. The aim of our study was to determine the predictors of progression after TACE in patients with HCC. Method: We retrospectively reviewed a total of 374 patients who had diagnosed as HCC and performed the fi rst TACE in our institution, Bundang CHA hospital, from 2004 January to 2013 September. Tumor response was estimated as CR (complete response), PR (partial response), SD (stable disease) and PD (progressive disease) based on the results of computed tomography 4 weeks after TACE with modifi ed RECIST criteria.Results: Among a total 374 patients, 13 patients(3.5%) had experienced previous TACE, and 361 patients(96.5%) were TACE naive. Most patients(n=370, 98.9%) had liver cirrhosis, 289 patients(77.3%) were classifi ed as Child-Pugh class A and 85 patients( 22.2%) as Child-Pugh class B. After 4 weeks after TACE, tumor response was as follows: CR 146(39.0%), PR 124(3.2%), SD 16(4.3%) and PD 88(23.5%). In patients with PD, there was a signifi cantly greater portion of TACE experienced patients compared to those with CR, PR, and SD(8.0 vs. 2.1%, p=0.016). The mean size of largest tumor and total sum of tumor sizes were signifi cantly greater in patients with PD(6.4 vs. 3.6 cm of largest tumor size, p<0.001; 7.0 vs 4.1 cm of total sum of tumor sizes, p=0.001, respectively). In multivariate analysis, previous TACE experience[Odds ratio (OR) 8.746, p=0.002] and a total sum of tumor sizes( = 3cm; OR 4.022, p=0.016, = 10cm; OR 9.153, p=0.008) were predictors of progression after TACE.Conclusion: Progression of HCC after TACE is associated with history of previous TACE experience and the total sum of tumor sizes. * Ga Won Song and Sun Young Shin contributed equally.

한가영(Ga-Young Han),김선희(Seon-Hee Kim) 한국화장품미용학회 2015 한국화장품미용학회지 Vol.5 No.1

Humans artistic creative activities have been expressed through natural beauty. Among natures creatures, bird is the subject of admiration and mystery because birds can fly freely in the sky and images of birds was an inspiration to a lot of artists. In this respect, the purpose of this study is to suggest to the basic data of the creative makeup design and studied fantasy makeup design with motif on the bird image for this purpose. The study collected data from domestic books and theses about birds and fantasy makeup. Based on this, produced four fantasy makeup works. Painting techniques could shape the feathers and applying a materials such as glitter, shimmer powder was effective in texture representation of the feather. This study could find out that the best formative material of birds is a feather through the work production process and the result. Various colors and types of wired wing feathers extend to the wing and shows the symbolic image of freedom and hopes. In addition, formative and the symbolism that appears in the image of birds has possibility of creating versatile makeup design. But this study has a limit that it made limited works focusing on the images of birds. Therefore, create artistic and formative image, theoretical and empirical studies should be conducted constantly from various angels.
