Characteristics of wind pressures on retractable dome roofs and external peak pressure coefficients for cladding design

YC, Kim,SW, Yoon,DJ, Cheon,JY, Song Elsevier 2019 Journal of wind engineering and industrial aerodyn Vol.188 No.-

<P><B>Abstract</B></P> <P>This study investigates the characteristics of wind pressures on retractable dome roofs. Wind tunnel tests were conducted on spherical dome roofs with various wall height-span ratios (0.1–0.5) and opening ratios (0%, 10%, 30% and 50%). After the characteristics of mean and peak pressure coefficients were examined, the peak pressure coefficients on closed dome roofs were compared with those of the current Japanese wind load code (AIJ-RLB (2015)), and peak pressure coefficients on dome roofs with openings for cladding design were proposed. The analysis results can be summarized as follows. As wall height-span ratio increases, the absolute values of mean and minimum pressure coefficients increase, and the absolute values of minimum pressure coefficients on the outermost interior of open dome roofs increase with opening ratio. For cladding design of dome roofs with openings, dome roofs were divided into two zones, and negative and positive peak pressure coefficients were proposed based on experimental results.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Characteristics of external pressures on retractable spherical dome roofs were investigated. </LI> <LI> Five wall height-span ratios and four opening ratios were considered. </LI> <LI> Absolute values of peak pressure coefficients were larger for the flow with <I>α</I> = 0.21. </LI> <LI> Absolute values of <I>C</I> <SUB> <I>pi,min</I> </SUB> increased with opening ratio and those for <I>α</I> = 0.21 were larger. </LI> <LI> Zones and external peak pressure coefficients for cladding design were proposed. </LI> </UL> </P>

최근 23세의 미산부에서 우측난소낭종염전 및 임신 제 7주의 임상진단하에 응급수술중 우연히 자궁근층 및 광인대내에 파괴성융모선종을 발견하고 자궁강내에서 육안적으로나 조직학적으로 그 월발소를 찾지 못한 희귀한 예를 경험하였기에 그 발생원인 및 치료에 관한 문헌적 고찰을 가하여 보고 하는 바이다. A rare case of chorioadenoma destruens, the primary focus of which was not found in the endometrium of uterine cavity either grossly or microscopically, was experienced during the operation for the right ovarian dermoid cyst in a 23 year-old woman. The molar tissue was noted in the deep layer of myometrium, mesosalpinx and broad ligaments.

Impact of perception of socioeconomic burden on advocacy for patient autonomy in end-of-life decision making: a study of societal attitudes

Kwon, YC,Shin, DW,Lee, JH,Heo, DS,Hong, YS,Kim, S-Y,Yun, YH SAGE Publications 2009 Palliative medicine Vol.23 No.1

<P>We investigated the impact of perception of socioeconomic burden on beliefs regarding a patient’s autonomy in end-of-life (EOL) decision making. We also sought to identify the characteristics of individuals who advocate patient autonomy and their attitudes toward other EOL issues. A total of 1055 individuals from the Korean general population were interviewed through a telephone survey using a structured questionnaire that was designed to investigate public attitudes toward various EOL issues. Of 1019 individuals included in the analysis, 635 (62.3%) specified the patient and 221 (21.7%) the family, when asked who is the appropriate decision maker in terms of EOL decisions in the absence of perception of socioeconomic burden. In contrast, the numbers were 458 (44.9%) and 500 (49.1%), respectively, if substantial burden was assumed. Respondents who favoured the patient’s right to make decisions regardless of perception of socioeconomic burden numbered only 312 (30.6%) and were likely to be younger and have knowledge of hospice than who favoured family decision. Former group also favoured the disclosure of terminal illness to patients, withholding life-sustaining treatment, and preparation of advanced directives. Societal attitudes toward patient autonomy were significantly influenced by perception of socioeconomic burden. Open and balanced discussion about burden to family and adequate welfare support are thus suggested.</P>

만기임신양수의 산염기균형에 관한 연구

신용철(YC Shin) 대한산부인과학회 1978 Obstetrics & Gynecology Science Vol.21 No.11

In recente year a number of components of the amniotic fluid have been noted to change progressively during pregnancy and accordingly have been intensively investigated as indicators of fetal maturity and well-beings for better management of mothers and babies. Amniotic fluid has also become of practical interest with the advent of dragnostic amniocentesis: water and solute exchange directly between amniotic fluid and various parts of pregnant uterus across extracellular membrane as extracellular compartment of human tissues. It is the object of the present study to show that a proper interpretation of the acid-base value of the amniotic fluid may offer important information about general conditions of the fetus and neonate. Experiments were designed with each group of twenty vigorous and depressed babies delivered by cesarean section under spinal anesthesia in healthy Korean women without O2 inhalation.l Acid-base values were measured in arterial blood of mothers radial artery and fetal umbilical vein, and amniotic fluid which aspirated just before taking out babies from amniotic sac. Following result were obtained: 1. Average values of partial pressure of oxygen and carbon dioxide and hydrogenion concentration(pH) in the amniotic fluid of twenty vigorous babies(above Apgar score 8) were 45 0.28 mmHg, 51 0.30 mmHg, and 62 0.34 nEq/L(pH=7.21) respectively. 2. Average values of partial pressure of oxygen and carbon dioxide and hydrogenion concentration(pH) in the amniotic fluid of twenty depressed babies(under Apgar score 4) were 20 0.21 mmHg. 80 0.20 mmHg, and 123 0.84 nEq/L(pH=6.91) respectively. 3. Correlation of hydrogenion concentration with PO2 and PCO2 was not observed. 4. There was a good correlation in the acid-base status of the amniotic fluid of vigorous and depressed babies with those of neonate. 5. It is suggestive that the values of acid-base status in amniotic fluid near term reflect the general condition of neonate and may serve the estimation of fetal status.
