Objective : To evaluate the normal change of the platelet count in maternal blood before and after delivery, vaginal or by cesarean section, following uneventful pregnancy. Background : Platelet counts tend to decrease progressively during normal pregnancy as gestation proceeds, though the levels remain within normal range. But, literature search gave no information regarding changes of platelet count in healthy women according to the increased gestational age and shortly after uneventful pregnancies. The intention of this study was to investigate whether there were any such changes. Methods : Thirty randomly selected healthy women with normal pregnancies, 15 delivered vaginally and 15 by cesarean section, participated in the study. Blood sampling were taken at 6-10th, 28th, 36th gestational weeks and on first day after vaginal delivery or cesarean section. Platelet count, hemoglobin concentration and hematocrit was measured for each blood sample. Results : At the 28th gestational weeks, decline of the platelet count becomes statistically significant. There was no significant changes in platelet count after delivery. Conclusions : Platelet count decrease in second trimester of pregnancy. But this remains unchanged shortly after uncomplicated delivery.

e 스포츠 시장의 급속한 발전과 게이머들의 요구 다양화에 따라, 게임 마우 스 디자인은 중요한 연구 분야가 되었다. 본 연구는 게임 마우스의 성능과 형태적 특징이 게이머의 구매 의도에 미치는 영향을 중점적으로 탐구하였다. 게임 마우스의 기술적 성능과 형태적 디자인에 대한 심층 분석을 통해 이러 한 특징들이 게이머의 특정 요구를 만족시키는 데 있어 핵심적인 역할을 한 다는 것을 발견하였다. 연구는 시장에서 인기 있는 게임 마우스에 대한 종합 적 평가와 게이머들을 대상으로 정성 방법을 통해 시장 조사 및 인터뷰를 포함하며, 게임 마우스의 특징에 대한 사용자 피드백과 선호도를 수집하여 어떤 특징들이 그들의 구매 결정에 가장 큰 영향을 미치는지를 이해하였다. 또한 한국과 중국 대학의 e 스포츠 동아리에서 총 106명 게이머들을 대상으 로 15일 동안 설문조사를 실시하였으며, 설문조사 결과 분석을 통해 게임 마우스의 클릭 수명, 게임 마우스의 무게, 크기, 게임 마우스의 그립 방식, 인체공학적 디자인, 무선 게임 마우스의 항속력 및 무선 게임 마우스의 연결 방식이 게이머들의 구매 의도에 주요한 영향 요인임을 보여주었다. 이러한 발견들은 게임 마우스 디자인에 가치 있는 지침을 제공하며, 제조업체가 게 임 시장의 요구를 더 잘 충족시키는 데 도움이 될 것이다. With the rapid growth of the e-sports market and the diversification of gamers' needs, game mouse design has emerged as a crucial research area. This study primarily focused on how the performance and morphological features of gaming mice affect gamers' purchasing intentions. Through in-depth analysis of the technical performance and design of gaming mice, it was discovered that these features play a key role in meeting specific gamer requirements. The research included comprehensive evaluations of popular gaming mice on the market, qualitative market surveys, and interviews with gamers. It aimed to collect user feedback and preferences on the features of gaming mice to understand which aspects most significantly influence their purchase decisions. Additionally, a 15-day survey was conducted among 106 gamers from e-sports clubs at universities in Korea and China. The survey results showed that the lifespan of clicks, weight, size, grip style, ergonomic design, battery life, and connectivity of wireless gaming mice are major factors influencing gamers' buying intentions. These findings offer valuable guidelines for gaming mouse design, helping manufacturers better meet market demands.

Ectopic pregnancy is an implantation of the fertilized ovum on a place except the endometrium. Most of the ectopic pregnancies are located at the fallopian tube. Few cases of retroperitoneal hematoma associated with ectopic pregnancy have been reported on previously; in each the retroperitoneal space had been the site of implantation. In contrast, we treated a patient with an ectopic pregnancy that implanted in the tube and then perforated through into the retroperitoneal space. To our knowledge this is very rare case of retroperitoneal hematoma caused by a ruptured tubal pregnancy.

Uterine prolapse is extremely rare during pregnancy. However in some cases significant complications such as urinary tract infection, voiding difficulty, abortion, and preterm labor may develop. Conservative management consisted of bed rest and use of a pessary. An elective cesarean section near term is the safest mode of delivery in cases where the cervix is edematous and elongated. We present a case of a patient developing uterine prolapse at 12 weeks of gestation, treated with bed rest and use of a pessary. A repeat cesarean section was performed at 38 weeks of gestation and report with a brief review of literatures.

The incidence of ectopic pregnancy has increased considerably a decade. And treatment has changed from salpingectomy by laparotomy to conservative laparoscopic surgery or medical treatment. This procedure has many advantages, but there are also disadvantages with the conservative approach and several studies have reported a higher incidence of residual trophoblastic tissue remaining in the tube after treatment. Postoperative follow up of human chorionic gonadotropin (hCG) levels and ultrasonography are needed. This report describes a rare case of persistent trophoblastic implants to the ovary and peritoneum 40 days after laparoscopic salpingectomy. Treatment consisted of laparoscopic excision with biopsy forceps and bipolar, followed by medical treatments. So we report with a brief review of literatures.

Dextran of a low molecular weight (dextran 40) is frequently used to improve regional perfusion after surgery in spite of the potentially serious complications such as noncardiogenic pulmonary edema, oliguric renal failure, and coagulopathy that have been
