김경애,정난희,모은자 한국 가정과 교육 학회 2003 한국가정과교육학회지 Vol.15 No.2

본 연구는 중학생들의 특기ㆍ적성 교육 활동 실태를 파악하고 여가만족과의 관계를 규명함으로써 여가 선용 및 특기ㆍ적성 교육 효과를 극대화 시킬 수 있는 방안을 제시하기 위한 기초 자료를 제공하고자 하였다. 본 연구에서 얻어진 결과는 다음과 같다. 1. 사회인구학적 변인에 따라 특기ㆍ적성 교육 활동 참여 실태는 여학생이 남학생보다 참여율이 높았고, 읍, 면 지역 중학생들은 모두가 참여한 반면에 광역시 중학생은 절반 정도만이 참여하였으며 시 지역에서는 거의 대부분이 참여하지 않는 것으로 나타났다. 가족의 소득이 높은 집단이 특기ㆍ적성 교육활동에 대한 참여율이 낮았으며, 부모의 학력이 높은 집단도 특기ㆍ적성 교육 활동 참여는 낮았다. 2. 사회인구학적변인에 따른 여가만족의 차이를 보면 심리적, 교육적, 사회적, 휴식적, 생리적, 환경적 만족의 6개 하위영역 중에서 읍, 면 지역 거주학생들이 광역시나 시 지역 학생들보다 높게 나타났다. 학년별로는 1학년 학생이 교육적 만족, 환경적 만족이 높았고, 가족의 소득이 높고 아버지의 학력이 높은 집단에서 여가만족이 더 높은 것으로 나타났다. 3. 특기ㆍ적성 교육 활동 참여 동기에 따른 여가만족은 참여 동기가 자신의 적성에 맞거나 진학을 위해서라고 하는 자발적인 의사결정의 결정에 높게 나타냈다. 참여 기간에 따라 참여 기간이 4개월 미만인 경우 높은 만족을 나타냈고, 집중도에 따른 여가만족에서는 모든 영역에서 집중도가 높은 집단의 여가만족이 높게 나타났다. The study has examined the relationship between the middle school students' after school activities and leisure satisfaction to provide the opportunity of making good use of leisure time and of developing students' latent talent and aptitude. The research finding are as follows : 1. Based on socio-demographic variables, the female students had more rates of participation in talent and aptitude educational activity than male students. The number of the students from rural areas was much bigger than that of cities such as Gwangju or other big cities in Chonnam. But the students whose parents made a lot of money showed less interest in participating talent and aptitude educational activities. 2. Based on the research of socio-demographic variables, students from counties or smaller areas showed more satisfaction than Gwangju in leisure satisfaction among the six subordinate categories. 7th graders were more satisfied in educational and environmental leisure activities than 8th or 9th graders. Moreover, as the family income is higher and as the father's educational level is higher, satisfaction rate from leisure activities cam out to be higher. 3. In regard to satisfaction they get from their leisure activities, it was comparatively high when they had the activities voluntarily as their hobbies or for fun. Some students regarded it as their chances for the next step and they were really satisfied, too. And also the period of time was one of the factors that affected students satisfaction. They were satisfied enough when they had the activities less than four month in a year. The students who had strong concentration and great enthusiasm showed high leisure satisfaction in all areas except for the environmental one.

The aerodynamic study of jetvane type TVC(Thrust Vector Control) were conducted using supersonic cold-flow system. The use of TVC Systems in particular jet vanes, are currently being researched for use in air launch, ship launch, underwater launch and high altitude maneuvering of tactical missiles and rockets. The necessity to generate control forces to rapidly change the course of the missile is frequently required when traditional, exterior aerodynamic surfaces are unable to produce these forces, when the flow over the control surface is insufficient. This situation can occur at launch, or high angles of attack of the control surfaces. Jetvanes performed well at all altitudes and environmental conditions, and jet vanes are extremely effective at deflection angles up to as high as 30 degrees, make them ideal for the launch and maneuver applications. In this study, aerodynamic performance test of jetvane type TVC was conducted, and The effect of shape and deflection angle of various types of jetvanes are investigated

레이더는 표적으로부터 반사된 신호의 크기, 도플러 속도로부터 표적의 거리, 속도 정보를 알 수 있으며, 이런 반사 신호의 특징들은 표적의 반사 특성과 기동에 의해 결정된다. 표적의 위치 정보에 대한 각도 오차는 합채널에 대한 차채널의 크기 비로부터 추출된다. 본 논문에서는 다기능 레이더의 성능을 평가하고 분석하기 위한 레이더 반사 신호 모의 장치(RSSE)에 대해 소개하였다. 개발된 레이더 반사 신호 모의 장치는 다채널 직접 디지털 합성(MC-DDS)을 이용하여, 재밍 신호를 포함한 다중 표적 환경을 모사할 수 있도록 구현되었으며, 효율적인 하드웨어 구조 설계를 통해 모사할 수 있는 표적의 수를 용이하게 확장할 수 있도록 설계되었다. 개발된 모의 장치의 요구 성능 및 기능을 시험 환경에서 확인하였으며, 신호 처리기(RSP)와의 연동 시험 구성에서 표적 탐지 성능을 입증하였다. Radar receiving echo signal provides target information - range, velocity and position by signal magnitude and Doppler shift, which are determined by target reflection characteristics and target maneuver. Target angle error is extracted from the magnitude ratio of difference channel to sum channel. In this paper, we introduce a radar Return Signal Simulation Equipment(RSSE) which is implemented for the purpose of performance analysis and evaluation of phased array multi-function radar(MFR). It generates multi-target environment with jamming signals using MC-DDS (Multi- Channel Direct Digital Synthesis), and has scalability by using the efficient hardware configuration. The performance of the developed RSSE has been evaluated under various test environments. Especially, we proved that required target detection performance is achieved by RSP(Radar Signal Processor) interfaced RSSE configuration.

Q fever is an acute (on occasion chronic) febrile illness caused by inhalation of Coxiella burnetii, and usually manifest as a self-limited febrile illness, pneumonia, endocarditis, hepatitis, skin rashes, myocarditis, pleuropericarditis, osteomyelitis, neurologic disease, hematologic diasease, or infertility and spontaneous abortion. Treatment with tetracycline, trimethoprim-sulfamethoxazole, doxycycline, or quinolone has been effective. We experienced a case of Q fever in a 5-year-old female patient. She complained of prolonged fever, abdominal pain and arthralgia of both knee on admission. She developed hepatitis, myocarditis, congestive heart failure, hepatosplenomegaly, pancytopenia, bone marrow necrosis and disseminated intravascular coagulation. Peripheral blood cell culture revealed Coxiella burnetii and hairy cells and antibody titer to phase I antigen was 1:160 by indirect immunofluorescent antibody assay. After intravenous chloramphenicol and oral rifampin, above symptoms and complications were improved. We presented a case of Q fever with a review of literatures.

Fluorescence-guided colorectal surgery: applications, clinical results, and protocols

Jin-Min Jung,In Ja Park,Eun Jung Park,Gyung Mo Son 대한외과학회 2023 Annals of Surgical Treatment and Research(ASRT) Vol.105 No.5

In recent years, the rise of minimally invasive surgery has driven the development of surgical devices. Indocyanine green (ICG) fluorescence imaging is receiving increased attention in colorectal surgery for improved intraoperative visualization and decision-making. ICG, approved by the U.S. Food and Drug Administration in 1959, rapidly binds to plasma proteins and is primarily intravascular. ICG absorption of near-infrared light (750–800 nm) and emission as fluorescence (830 nm) when bound to tissue proteins enhances deep tissue visualization. Applications include assessing anastomotic perfusion, identifying sentinel lymph nodes, and detecting colorectal cancer metastasis. However, standardized protocols and research on clinical outcomes remain limited. This study explores ICG’s role, advantages, disadvantages, and potential clinical impact in colorectal surgery.
