Brain morphology according to age, sex, and handedness
강세진,강경아,장한,이재윤,이강일,권민석,김정수,박강민 대한임상신경생리학회 2017 Annals of Clinical Neurophysiology Vol.19 No.2
In this article, we review the differences of the brain morphology according to age, sex, and handedness. Age is a well-known factor affecting brain morphology. With aging, progressive reduction of brain volume is driven. Sex also has great effects on brain morphology. Although there are some reports that the differences of brain morphology may originate from the differences of weight between the 2 sexes, studies have demonstrated that there are regional differences even after the correction for weight. Handedness has long been regarded as a behavioral marker of functional asymmetry. Although there have been debates about the effect of handedness on brain morphology, previous well-established studies suggest there are differences in some regions according to handedness. Even with the studies done so far, normal brain morphology is not fully understood. Therefore, studies specific for the each ethnic group and standardized methods are needed to establish a more reliable database of healthy subjects’ brain morphology.
신생아의 혈장 Atrial Natriuretic Peptide치에 관한 연구
강세진,독고영창 고려대학교 의과대학 1990 고려대 의대 잡지 Vol.27 No.3
The authors studied on plasma atrial natriuretic peptide ( ANP ) concentration of umbilical arteries, umbilical veins and peripheral veins of neonates aged 2 days in 33 healthy neonates delivered in Korea University Medical Center from April 1989 to July 1989 and also studied that of peripheral veins of 11 healthy neonates aged 28 days who had visited department of pediatrics. The atrial natriuretic peptide was measured by the method of radioimmunoassay. (research and diagnostic antibodies, Berkeley, CA USA) The results obtained were as follows : 1. Mean plasma ANP values of umbilical arteries, umbilical veins and peripheral veins of neonates aged 2 days born by vaginal delivery were 139±6 3 pg /ml, 74±30 pg /ml and 213±59 pg /ml, respectively. Mean plasma ANP values of umbilical arteries, umbilical veins and peripheral veins of neonates aged 2 days born by cesarean section were 129±49 pg/ml, 80±22 pg/ml and 205±44 pg/ml, respectively. Mean plasma ANP values of neonates aged 28 days were 61k26 pg /ml. 2. Mean plasma ANP values of umbilical arterial blood was higher than that of umbilical venous blood, both in neonates born by vaginal delivery and in those delivered by cesarean section (P<0.05). 3. Mean plasma ANP values of peripheral venous blood of neonates aged 2 days was higher than that of umbilical venous blood, both in neonates born by vaginal delivery and in those delivered by cesarean section(P<0.05). 4. In comparison of mean plasma ANP values of neonates aged 2 days and that of neonates aged 28 days, higher values were observed in neonates aged 2 days(P<0.05). 5. There was no statistical difference between mean plasma ANP value of neonates born by vaginal delivery and that of neonates delivered by cesarean section.

In food processing, polycyclic aromatic hydrocarbons(PAHs) can be generated during heat treatment,and the PAHs in seasoned-roasted (SR) laver can bereduced by checking points during manufacturing. Benzo(a) anthracene, chrysene, benzo (b) fluoranthene, andbenzo (a) pyrene have been identified in SR laver via GC/MS. We confirmed that in practice, the PAHs in SR laverform from the mixed oil (57%) and roasting process (43%). To mitigate the formation of PAHs, we used a modelsystem to change the mixing ratio of oil, roasting temperature,and time. A significant reduction (35%) wasobserved in the PAH level as the perilla oil was removedfrom the mixed oil composition and roasting continued at350 C for 10 s. These results show that the composition ofthe mixing oil and the parameters of the heat treatment arecrucial factors that contribute to the formation of PAHs inroasted laver.

The purpose of this study is to analyze physical charateristics of residential areas in Seoul. The chosen study areas are 338 zones in 19 Gu, where investigated for devising master plan, of which contents are maintenance of urban and residential areas, by Seoul Metropolitan Government in 2003. The implementation of this study can be summarized as follow. First, the level of density, in which a residential area can be called "deteriorated", is more than 70 housing units, which are only in the first floor, per ha. A residential area at this density has few open spaces or narrow roads, therefore newly built housing in this area are decreased than in other favorable areas. Second, noticeable relation, which are observed within density of residential areas(DR), size of building lots(SL), ratio of housing by appropriate roads(RAR) and ratio of deteriorated housing(RDH), are that RDH are increasing, on the other hand, SL and RAR are decreasing, while DR are increasing. Third, deteriorated residential areas are mostly squatters, which have been settled by immigrant from rural districts before 1970's, or low-grade development areas, which have been hurriedly developed by the Government or private developers for solving housing insufficiency before 1970's.
