      • GG-38 : Minimal invasive surgery (LESS) for huge cystic adnexal tumors in whole abdomen

        ( In Young Choi ),( Ji Hye Lee ),( Mi Hyun Park ),( Ji Kwoun Park ),( Jeong Kyu Shin1 ),( Won Jun Choi1 ),( Soon Ae Lee ),( Jong Hak Lee ),( Won Young Paik ) 대한산부인과학회 2014 대한산부인과학회 학술대회 Vol.100 No.-

        Laparoendoscopic single-site surgery (LESS) is helpful if not an evidence of suspicious malignancy in huge adnexa tumors. This approach might be reasonable alternative to conventional laparoscopic surgery. We report two cases with LESS for huge cystic adnexal tumors in whole abdomen. A 58 years old multigravida woman in menopause underwent removal of a huge cystic adnexal mass that occupied her entire abdomen by LESS.(ca.5200ml aspiration) A 15 years old single nulligravida woman had a huge cystic adnexal tumor in whole abdomen reaching to the level of the xyphoid process. A needle through the transumbilical single port was inserted directly under the mass. Subsequently, 8000 ml of cystic fluid was aspirated without spillage.

        Pollen metabarcoding reveals the floral resources and niche overlap of honeybees in forest areas

        Do Yuno,Park Woong‐Bae,Park Jun‐Kyu,Kim Chang‐Jun,Kim Il‐Kwon,Choi Moon Bo 한국곤충학회 2022 Entomological Research Vol.52 No.12

        We investigated the floral resources of the honeybee (Apis mellifera)bypollenDNA metabarcoding as the first step in honeybee conservation. We attempted to identify as many floral resources and as wide resource availability as possible in areas and compared the richness of floral resources between forests and national parks. We found that both forest and national parks can sufficiently support honeybee floral resources; however, national parks were more stable habitats with more complex vegetation structure than those of forests. Also, honeybee’s preferences for floral resources were determined using niche breadth, niche overlap, and network analysis among the floral resources in forest areas. Quercus and Actinidia were the most frequently detected taxa of pollen resources in both forests and national parks by pollen metabarcoding. Even though we anticipated that more various pollen resource taxa would be found in national parks than forests, no differences in the number pollen resource taxa were detected between them. According to the niche overlap analysis result, the honeybee preferred the pollen resources in both forests and national parks, and the co-occurrence pattern analysis of pollen resource taxa in both forests and national parks showed a simple network. Altogether, our findings suggested that DNA metabarcoding of pollen collected by the honeybee can provide useful information on the flowering plants in a given area. As the use of floral pollen resources varies spatially and temporally, periodic monitoring of pollen resources can identify which pollen is required to maintain the health of honeybee colonies.

        Development of a Reduction Algorithm of GEO Satellite Optical Observation Data for Optical Wide Field Patrol (OWL)

        Sun-youp Park,Jin Choi1,Jung Hyun Jo,Ju Young Son,Yung-Sik Park,Hong-Suh Yim,Hong-Suh Yim,Hong-Kyu Moon,Young-Ho Bae,Jang-Hyun Park 한국우주과학회 2015 Journal of Astronomy and Space Sciences Vol.32 No.3

        An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development, the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of the positions of these GEO satellite candidates, the final coordinates could be calculated.

        혼합치열기 전치부 반대교합 아동에서 Fra¨nkel functional regulator III의 치료효과

        박정아,양규호,최남기,김선미 大韓小兒齒科學會 2008 大韓小兒齒科學會誌 Vol.35 No.4

        본 연구는 혼합치열기 전치부 반대교합 어린이를 대상으로 FR III가 치아와 골격의 성장에 미치는 효과를 평가하고자 하였다. FR III로 처치한 전치부 반대교합을 지닌 30명의 아동(평균나이 7.9 ± 1.1세 : 평균 치료기간 1.5 ± 0.8년)을 대상으로 치료 전후의 측모 두부방사선 사진을 분석하여 다음과 같은 결과를 얻었다. 1. 상악에 대한 FR III의 골격적인 효과는 상악의 하방이동이며, 전방이동은 대조군과 유의한 차이를 보이지 않았다. 2. 하악에 미치는 FR III의 골격적인 효과는 하악의 후하방이동과 SNB의 감소이다. 3. 치아에 대한 FR III의 효과는하악전치 첨부의 후방이동과수평피개의 증가였다. 이상의 결과로 단기간의 FR III 치료는 상악골의 전방이동 촉진효과는 미미하며 상악골의 하방이동, 하악골의 후하방 회전, 수평피개 증가효과가 있음을 알 수 있었다. The purpose of this study was to evaluate the skeletal and dental effects obtained by the Frankel functional regulator III in growing children with Class III malocclusions. Cephalometric changes in thirty children at the time of mixed dentition malocclusions(initial mean age, 7.9 ± 1.1 years; mean treatment duration. 1.5 ± 0.8 years) were analysed. The results were as follows : 1. The skeletal effects on the maxilla showed a significant downward displacement whereas forward displacement was not significant in comparison with the control group. 2. The skeletal effects on the mandible showed statistically significant backward and downward displacement. 3. The dental effects showed statistically significant backward movement in the mandibular incisor tip and increase of overjet. The results suggested that forward displacement on the maxilla was insufficient and treatment effects were caused mainly by downward displacement of the maxilla, backward and downward rotation of the mandible, and the increase of overjet during short period.

      • 대형할인점 리모델링 프로젝트의 CM at Risk 적용 타당성에 관한 연구

        최규산,이호경,박영호,백준홍 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.2

        Remodeling projects are on a increasing trend because of the old buildings built in 1960-70's, the preference for energy saving and the changes of social demands and government policies, etc. And also discount-store projects, which are rapidly increasing, are characterized by the fact that they are repetitive and have analogous scale and structure. Therefore, it is necessary to develop the concept discount-store model and apply the appropriate project delivery system for a successful execution of the projects. The purpose of this study is to analyze the characteristics of the discount-store remodeling projects and propose CM at Risk for the optimum delivery system of those projects.

      • 農業構造變化와 農業金融問題의 再認識

        朴正根,崔圭晧 全北大學校 1978 論文集 Vol.20 No.-

        This study presents crucial features of structural changes in agriculture and their applications to farm finance problems. The rapid growth of economy since the 1960's in Korea, has accelerated the pace of industrialization and urbanization. Its influences have caused agricultural transformation. The process of structural transformation has been based on the interrelationships between agriculture and industry through the market for capital and labor. The rapid economic development has stimulated a great number of rural people to migrate to large cities, so the number of agricultural workers has begun to decline since 1968. Therefore, in the past, labor was the most important input of agricultural production. Nowadays, because of the shortage of labor, observations concerning the relative changes of resource inputs in agricultural production indicate that capital acts as a major factor in the substitution for labor in the expansion of agricultural output. At the same time, wide-scale substitution of capital for labor has come about because of the technological progress based on labor-saving and capital-augmentation. On the other hand, as economic development continues to increase nation's per capita income, the commodities with higher income-elasticity, which are produced mainly for market by specialized producers have also increased rapidly. Thus, increased technological progress and marketing functions have contributed to structural change, namely, the farmers purchase more of their inputs which, in turn, encourage the changes in the financial structure of the farm sector in Korea. In order to adapt to the rapid structural changes farmers are required to have a larger amounts of capital than they have had in the past, so their liquidity position is increasing. The rapidity with which these developments emerged has created problems with some credit agencies financing farmers. However, it has been generally assumed that in subsistence agriculture rural people are too poor to save, and farm finance problems have received relatively little attention. But now, on the demand side of capital, modernizing agriculture requires large infusions of credit to finance the use of purchased inputs. On the supply side of capital, the experimental data developed in Korea recently showed that rural households have save a significant part of their incomes even though per capita incomes were quite low. This situation indicates that in farm finance Korean agriculture has arrived at the threshold of a new era. The changes in the financial structure of agriculture necessitate us to examine some of the accompanying problems and implications. From the individual farmer's standpoint farm financial management will become more important and will consume a larger proportion of the operator's time. Credit agencies will meet more nearly the challenges of greatly increased credit needs, and must perform the function of transferring savings between sectors, between regions and between income classes. To insure economic progress and an equitable distribution of its profits, policy makers should prepare to create and nurture a strong appropriate institutional program.

      • 아파트 내부공간에 대한 거주 후 평가 : 주공아파트 17평형을 대상으로 The 17 Pyung Size Housing Apartments Built in Korean National Housing Corporation

        최보가,최무혁,박규정 경북대학교 1992 논문집 Vol.24 No.-

        The purpose of this study is to make use of these materials for the next housing plan and to put emphasis on post occupancy evaluation. For this study, the apartments occupied are chosen and the degree of satisfaction with residence is examined, in real occupants' respect. As the objects, the apartments built by the Korean National Housing Corporation in 3 apartment sites of Taegu in 1979, 1983, 1985 is selected. The apartment size is restricted to 17 pyung. SPSS(Statistical Package for Social Sciences) is used as an analysis method and the degree of satisfaction is divided into 5 grade using Likert measurement to give objectivity. After the analysis, the degree of satisfaction with each apartment is compared and analyzed through Duncan's Multiple Test. The results are as follows. 1. In the satisfaction with each room, the degree of bathroom, kichen and dining room, balcony, entrance showed meaning difference. 2. Many factors out of evaluation factors showed meaning difference partly of room 1, room 2, room 3, kichen and dining room, bathroom utility room and boiler room, balcony in the degree of satisfaction with each apartment. 3. The improved factors, the factors which need to improve, the factors to which the occupants adapted themselves among evaluation factors are classified on the basis of standard satisfaction.

        최경호,오동렬,이원재,박규남,박승현,황두영,김형국,정시경,김영민,김세경 大韓應急醫學會 1998 대한응급의학회지 Vol.9 No.4

        To evaluate appropriate diagnostic studies for renal infartion in emergency medical center, we analysed 33 patients of renal infarction treated in this hospital for last 8 years. Eleven patients, 4 trauma associated and 7 aortic disease associated patients were excluded. They are 11 males and 11 females with a mean age of 51 years. Fourteen came to the emergency medical center and seven came to the outpatient department, in the other one patient renal infarction was developed during hospitalization with other disease. On their past history they had hypertension in 9, valvular heart disease in 5, and diabetic mellitus in 4 patients. Abdominal or flank pain was noted in 17 of 22(77%). The other symptoms were vomiting, nausea, fever and so on. On microscopic examination of initial urine in hospital, 5 patients showed more than 10 red blood cells by high power field examination. The mean lactic dehydrogenase level was 1,239 I.U/L(normal range 218-472 I.U/L), while the mean aspartate aminotransferase and mean alanine aminotransferase were 51 I.U/L(normal range 13-36 I.U/L) and 44 I.U/L(normal range 5-33 I.U/L). Abdominal ultrasonography showed positive findings in 5 of 16(31%), of which 3 were confirmed by Doppler ultrasonography. In 18, computed tomography was done and all those showed positive findings of renal infarction(100%). In conclusion, it is important that identify the elevated lactic dehdrogenase level in case of any suspicion about renal infarction and confirm by computed tomography.
