Long time ultrasound scan can cause a temperature rise in human tissue and affect the physical body. This is closely connected with patients' safety. So many researchers have been studied on this matter with animals such as mammals and experimental rat, because diagnostic ultrasound has been used many types of human organ to find disease. Therefore, this study is tested on bean sprouts to search how far the tissue temperature changes because of the excessive scanning consequence from ultrasound diagnosis and frequent number of ultrasonic scanning and how much affect their growth. The United States and several European countries have restrictions for number of scanning, while South Korea does not have any limitation for using ultrasound diagnosis. Comparison was that how different condition affect its' growing. The testing group is like many pregnancy moms to have 50 minutes in B-mode and color doppler mode by linear, convex and sector probe every day for a week and the other is to scan only once during the testing period. As a result, it was confirmed that there was a significant growing difference on frequent ultrasonic scanning group compared to normal one. So the final conclusion is that there needs to have a significant limitation of ultrasound scan time and a number of inspection when having for diagnostic ultrasound and recommendation like USA and a few European countries.

본 연구는 학교 체육교과내용으로서의 무도수업의 특성과 효과를 탐색하여 학교 수업으로서의 무도수업의 가치를 재정립하고 이를 통해 무도가 공교육으로서 효율적이고 지속적으로 실시되고 정착할 수 있도록 하는데 연구의 목적이 있다. 이러한 목적을 달성하기 위한 연구방법으로는 무도수업 및 수련의 특성과 효과에 관련된 각종 문헌자료를 바탕으로 그 속에 내재되어 있는 가치를 탐색하였다. 무도수업은 남녀 혼성수업이 가능하며, 기능 수준에 관계없이 함께 교육할 수 있다. 무도수업은 남녀 모두 도복만 준비하면 실내의 좁은 장소에서 계절과 날씨에 구애받지 않고 수업을 할 수 있다. 부가적으로 수업을 마치고 기능 수준이 높아지면 평가를 통하여 승단을 할 수 있다. 승단을 하면 군인, 경찰공무원시험 등에서 가산점을 받을 수 있다. 무도는 신체수련과 동시에 `예로 시작해서 예로 끝난다.`는 말과 같이 정서적인 면의 예의를 기를 수 있다. 수련을 하면서 상대선수, 지도자, 심판에게 올바른 예의범절과 태도로 행동할 것을 강조한다. 또한, 대인 투기경기인 무도는 상대와 겨루는 가운데 인내력과 도전정신, 긍정적 인간관계 등을 배우게 되어 신체적, 정서적으로 감수성이 예민한 학생들의 바람직한 생활태도 형성에 도움을 줄 수 있다. 무도수업을 통하여 다양한 기술을 배우고 숙달함으로써 타인으로부터의 공격이나 위급한 상황에서 자신의 신체를 보호하고 이겨낼 수 있는 호신의 능력을 갖게 된다. The purpose of this study is about searching character and effect of martial art as physical education and to establish martial arts`s value by sustaining it as the public education. For the purpose of the study, it adopts the descriptive methods to review features and effects of martial arts in various literatures to know its value. The martial art class can have male and female students in the same class regardless of a level of technique. Once students prepare uniforms, the class can proceed in a small indoor place regardless of weather or season. Additionally, they can achieve a degree promotion as their technique improves. The promotion may help to get additional points in various public examinations such as military or police exams. Martial art helps students build mental manners as shown at the proverb `It begins with manners and ends with it` along with physical training. It emphasizes to behave with right etiquette and attitudes toward a respective player, a trainer and a referee during a drill. In addition, it can help to build desirable life attitude of the students who are physically and emotionally sensitive as they learn patience, challenging spirit and positive human relations while having a drill with the other player. As students learn various techniques through martial art, they can protect their own bodies in an emergency situation or from others` attack.

본 연구는 대전, 충청지역 초음파실 종사자를 대상으로 병원감염관리에 관한 설문 조사를 실시하여 분석 하였고, ATP를 이용하여 임상에서 사용되는 초음파 Probe의 오염도를 측정하였으며, 70% 알코올 이용하여 소독한 후 결과를 확인하였다. 기본적인 조사 대상자의 일반적인 특성 및 직종 별 대상자의 특성으로 나누어 학력, 직종, 초음파 전문자격증 보유 유무, 기관 내 감염 담당 부서 및 감염 교육의 여부를 분석하였다. 검사 후 젤 제거 여부 및 방법, Probe의 소독여부 및 변수 별 상관분석을 수행하여 초음파 Probe의 세균감 염에 관한 인식 및 세척 및 소독에 대한 수행 정도를 분석하였다. 검사 후 Probe 세척에 관하여 수건을 가장 많이 사용하였으며, Gel 용기는 3개월 이상 교환하지 않는 것으로 나타났다. 70% 알코올 소독 후 ATP 오염도는 1055.4±944.2에서 133.5±93.2으로 감소하였고 통계적으로 유의한 것으로 분석되었다.(ρ<0.01) 병원 균종은 CNS, Gram positive bacillus, Micrococcus species 검출되었다. 이를 해결하기 위해 시중에서 손쉽게 구할 수 있는 70% 알코올을 이용하여 소독을 실시하였으며 소독 후 병원균종은 검출되지 않았다. 연구 결과 초음파실을 관리하는 의료인 또는 의료기사 등은 감염관리에 대한 주기적인 교육과 감염예방에 대한 노력이 필요하다고 볼 수 있으며, 70% 알코올은 병원균 사멸에 효과적인 것으로 나타났다. 따라서 의료기 관은 적극적인 병원감염관리 교육을 실시하여 종사자들의 병원감염에 관한 인식을 개선하고, 환자 감염 예방에 기여해야 할 것이다. 또한 본 연구 결과를 적절히 활용한다면 초음파 Probe를 매개로 한 감염 예방에 도움이 될 것으로 사료된다. The study was conducted surveying ultrasound room workers on hospital infection awareness in Daejeon and Choong-chunng region. The contamination of ultrasonic probes used in clinical trials was measured using ATP, and the results were verified after using 70% alcohol sterilization. It was measured on the group’s general characteristics and the specific categories such as academic background, job type, having professional certificate and infection education. After the examination, the gel removal and method, disinfection status of the probe and variable correlation analysis were performed to analyze the recognition of the ultrasonic probe disinfection. After examination in ultrasound room, it was found that towels were used the most for cleaning, and the gel container was not replaced for more than three months. After 70% alcohol disinfection, ATP contamination was reduced from 1055.4±944.2 to 133.5±93.2 and the result was analyzed to be statistically significant.(ρ<0.01) The found bacteria were CNS, Gram positive bacillus, and Micrococcus specs. In order to solve this problem, 70% alcohol sterilization was applied and the bacteria were not detected after the treatment. The research shows that regular training on infection control and efforts to prevent infection are necessary, and that 70% alcohol is effective in disinfect the bacteria. Therefore, the medical institution should provide active hospital infection control education to improve the awareness of hospital infection among workers and contribute to the prevention of patient infection. It is also understood that proper use of the results of this study will help prevent infection by means of ultrasonic probes.
