The primary aim of this study was to analyze public perceptions of the Saemangeum World Jamboree. This event drew significant attention in August 2023 due to various challenges, including typhoons and preparation issues. A substantial amount of unstructured data was gathered from significant portal sites. According to the TF-IDF (Term Frequency-Inverse Document Frequency) analysis, between August 1st and 7th, 'world' and 'Saemangeum' were the predominant keywords, accompanied by related terms like 'heatwave,' 'typhoon,' and 'campsite.' Centrality analysis revealed that 'World Jamboree' and 'Saemangeum' were at the core of the network discussions. Following the early closing of the event, the 'Super Live Popcorn Concert' became a prominent keyword. The CONCOR (CONvergence of iterated CORrelations) analysis indicated that from August 1st to 7th, keywords such as 'World Jamboree', 'participants,' and 'Buan County' were closely linked. From August 8th to 12th, the focus shifted to keywords like 'Super Live Popcorn Concert,' 'Seoul,' and 'conclusion,' forming the main clusters. In conclusion, the study confirmed that the World Jamboree in Saemangeum garnered significant domestic and international attention. It provided a detailed analysis of public reactions to various issues associated with the event and the evolution of related keywords over time. The findings from this research offer valuable insights for planning and managing similar events or festivals in the future.

To determine whether hormone analysis of amniotic fluid could be used for accurate determination of fetal sex, we measured testosterone(T) and follicle-stimulating hormone in 19 amniotic fluid samples. The mean T in amniotic fluid of 8 women earring male fetuses was 310 pg. per milliliter and of 11 women earring female fetuses was 150 pg. per milliliter (P<0.05${\ast}$). The mean amniotic fluid FSH of 1.16 mI.U. per milliliter for 7 women with male fetuses was over trifold lower than that for subjects with female fetuses. The mean amniotic fluid FSH of female fetuses was 3.85 mI.U. per milliliter (P<0.01${\ast}$) Measurement of T & FSH in amniotic fluid may be an adjunct method for fetal sex determination.

종양표지물 생성 세포주 배양시 배양액내 혈청농도와 종양표지물인 홀몬의 분비양상과의 관계를 규명하여 실험에 적합한 배양액내 혈청농도를 알아 내고자 난소종양 세포주인 Bix2NMB와 Bixler를 무혈청 및 5, 10, 15, 20%의 혈청을 가진 배양액내에서 배양하여 세포성장과 total hCG, 베타 hCG, 베타 core fragment의 분비를 측정하였다. 세포를 배양하여 매일 성장을 측정하고 그 배양액을 채취 수집하여 냉동 보관하였다가 ELISA를 이용하여 총 hCG, 베타 hCG와 베타 core fragment를 측정하였다. 난소종양세포주들의 성장은 무혈청 배양액에서는 이루어 지지 않았으며 5%에서 20%까지의 다양한 혈청함유 배양액에서는 거의 유사한 형태의 성장곡선을 나타내었다 (p>0.05). 총 hCG와 베타 core fragment는 생성되지 아니했거나, 극미량 측정되었으나, 베타 hCG 의 생성량은 충분하였다. 아울러 베타 hCG의 분비는 혈청농도의 증가에 따라 비례하여 증가한다는 것을 알았다. 위의 현상으로 보아 혈청은 종양세포의 성장과 생존에 필수적인 요소로 생각되며, 혈청함유 정도에 따른 성장곡선의 형태는 유사하였지만 홀몬의 분비량에는 차이가 있는것 (p<0.05)으로 보아 종양세포 배양시 적당한 혈청 배양농도의 선택은 실험에 매우 중요하다고 사료된다. 즉 세포배양실험시 세포성장의 정도만으로 표지물의 분비 또는 생성의 정도를 초청하여 서는 실험의 최적 조건을 찾을 수가 없음을 알 수 있다. Cell growth rate and the secretion of ectopin hormones such as human chorionic gonadotropin(hCG), free β-subunit and β core fragment of hCG, were measured in the culture media with various serum concentrations from ovarian carcinoma cell lines, Bixler and Bix2NMB. The concentrations of fetal bovine serum contained in the culture media that showed the most active cell growth and hormone secretion were investigated to decide the best optimal serum concentration as one of the appropriate culture conditions in the experiment using cell culture. Ovarian concer cells were not able to proliferate in the media without serum. Cells proliferated more actively in higher concentration of serum. They secreted more hormone according to the increment of confluency as long as they secreted hormone. These findings suggest that serum is essential for surviving and cellular activity of cancer cells. The selection of the optimal serum concentration of culture media is very important to get appropriate data from the experiments which use cell culture technique. It is considered that we must have the knowledge on the most efficient concentration of serum in the culture media or on the exact percentage of serum in the media that matched to that of in vivo.

자궁방광간 복막오목 (Uterovesical Pouch) 결손 산모에서의 제왕절개술 1 예

The urinary and reproductive systems are closely related both anatomically and embryologically that must be inevitably considered together. In all vertebrates there is a complex system of body cavities which are mesodermal in origin and from such spaces as the pleural, the pericardial, and the peritoneal cavities. They are lined by a layer of flattened cells or mesothelium and are often spoken of as serous cavites. These cavities give us an easy access to the target organ when we do surgeries. Their surfaces are covered with a film of moisture which allows free movement of the visceral surfaces upon each other. Fusion of the paramesonephric ducts brings together two peritoneal mesenchymal folds, which form the right and left broad ligaments and 2 peritoneal compartments of pelvic cavity, the uterorectal pouch of Douglas and uterovesical pouch. Well formed uterovesical peritoneal pouch enables us to incise the lower segment of uterus easily. We confronted the difficulty of approaching to the uterus for low segment transverse incision in pregnant woman with uterovesical pouch defect who had never undergone pelvic surgery and no history of any pelvic inflammatory diseases. So it could be hypothesized that the defect of uterovesical peritoneal pouch can be occur by erroneous development prenatally.

The importance of security in the aviation sector has continued to be emphasized since the September 11 attacks. And recently, the development of science and technology has introduced a new technology called bio-metric by combining airport security and service fields. This study confirmed the perception of the general public using air travel related to airport bio-metric. In the process, text mining techniques were used instead of using questionnaires, which were widely used in previous studies. Main keywords were collected from Naver, Daum, and Google using the Textom 4.0 program that can analyze Korean. The collected words were frequency analysis, TF-IDF analysis, centrality analysis, and CONCOR analysis. The results of the CONCOR analysis are as follows. Group 1: Airport bio-metric activated after COVID-19, Group 2: Airport that can register bio-metric, Group 3: Shortening boarding procedures and times, Group 4: Korean air Self-boarding, Group 5: Airport-linked services, Group 6: Mobile driver's license available at the airport, Group 8: Resident registration card that can be issued on smartphones. Based on these results, this study confirmed the general public's perception related to airport bio-metric and suggested implications for academia and industry.

자궁각임신의 임상적 고찰

고민환,박윤기,이용훈,이호열,박성준,이강혁 대한산부인과학회 1999 Obstetrics & Gynecology Science Vol.42 No.4

목적: 자궁각 또는 난관간질부임신은 그 발생빈도가 희귀하다. 빈도는 대략 모든 난관임신의 2-4%를 차지하지만, 심각한 이환율과 사망률을 보인다. 저자들은 본원에서 경험한 자궁각임신 37예를 임상적으로 분석고찰하여 보고함으로써 자궁각임신의 진단과 치료에 기여하고자 한다. 방법: 1983년 5월 1일부터 1998년 12월 31일까지 영남대학교 의과대학 부속병원 산부인과에 입원하여 자궁각임신으로 개복수술 및 보존적치료를 받은 37명을 대상으로 고찰을 시행하였다. 결과: 자궁각임신의 전자궁외임신에 대한 비율은 1:35.1이었으며, 실혈성 shock이 다른 자궁외임신보다 흔했고 복강내 출혈양은 500ml미만이 35.1%, 2000ml이상이 24.3%이었다. 임상증상의 발현은 최종 월경일로부터 8-12주에 54.1%로 가장 많았으며 치료는 자궁각절제술이 70.3%, 전자궁적출술이 24.3%를 차지하였다. 결론: 자궁각임신은 치명적인 결과를 줄이기 위해 조기진단이 중요하며, 전통적인 수술법이외에도 복강경을 이용한 보존적 또는 비보존적 치료방법들과 약물치료방법등도 유용성이 높다고 사료된다. Objective: Cornual or interstitial pregnancy rarely occurs. Its incidence is estimated 2-4% of all tubal pregnancy, but it causes serious maternal mortality and morbidity. The authors surveyed 37 cases with cornual pregnancy and propose analysis from the clinical statistical aspect. Methods: We studied 37 cases which have occured from May. 1, 1983 to Dec. 31, 1998 at Department of Obstetrics & Gynecology, College of Medicine, Yeungnam University, Daegu. Results: The incidence of cornual pregnancy was 1 in 35.1 ectopic pregnancies. Shock was more frequent, intra-abdominal hemorrhage below 500ml was 35.1%, above 2,000ml was 24.3%. The most frequent interval between LMP and the onset of symptom was 8-12 weeks in 54.1%. 70.3% of total cases were treated by cornual wedge resection, 24.3% by total abdominal hysterectomy. Conclusion: Early detection of cornual pregnancy is essential in avoiding a fatal outcome. Although most of cornual pregnancies were treated with traditional operative techniques, it is useful to conduct conservative or non-conservative management by laparoscopy and treat medically.
