  • This study investigated the effects of Origanum majorana essential aroma therapy on electrical activity in the brain as evaluated by an electroencephalogram (EEG). The subjects were 29 healthy female young adults, and their sleep quality was assessed by using the Pittsburgh Sleep Quality Index. EEG electrodes were attached at the frontal, temporal, occipital, and parietal lobes according to the international 10-20 system. Subjects were exposed to organic Origanum majorana essential aroma (50 ${\mu}l$) for a period of 3 minutes each before, during, and after aromatherapy. Subjects with good sleep quality showed that Origanum majorana essential aroma increased the theta power at the frontal and temporal lobes of both cerebral hemispheres, the left parietal lobe, and the right occipital lobe. Furthermore, Origanum majorana essential aroma decreased the alpha power at the left occipital lobe and the beta power at the right temporal lobe. On the other hand, subjects with poor sleep quality showed an increase in the theta power at the temporal lobe of both cerebral hemispheres and a decrease in the alpha power at the left parietal lobe by Origanum majorana essential aroma therapy. It is concluded that Origanum majorana essential aroma therapy diminishes the state of wakefulness in the brain; alpha and beta powers were both decreased in the subjects with good sleep quality, but only alpha power was decreased in the subjects with poor sleep quality. Moreover, Origanum majorana essential aroma therapy has a sleep-inducing effect in both subjects with good sleep quality and poor sleep quality.

  • The purpose of this study was to develop a STEAM-based science education program for children and to verify its effectiveness. An S-STEAM-based science education program for young children was developed through careful analysis of prior research on science education for young children and S-STEAM. The participants were 29 four-year-old children from daycare centers located in Seoul (an experimental group of 14 and comparative group of 15). The S-STEAM program was applied to the experimental group, while the control group went through a general science education course provided by the government. TTCT of Creative Thinking (TTCT: Figures A and B) was used as a research tool, and a multiple intelligence test tool was applied to teachers of the groups. Afterwards, analysis of covariance was implemented to find the S-STEAM program's effects. First, the results showed positive effects on overall creativity, as well as in fluency, originality, abstractness, elaboration, and openness components of creativity. Second, the results showed positive effects on overall multiple intelligences and its components of linguistic, musical, spatial, logical/mathematical, physical exercise, interpersonal, and naturalist intelligence.

  • Contrast-enhanced CT has an important role in assessing liver lesions, the optimal protocol to get most effective result is not clear. The mein goal when deciding injention protocol is to optimize lesion detectability with rapid scanning when lesion to liver contrast is maximum. For this purpose, we developed a physiological model of the contrast medium enhancement based on the compartment modeling and pharmacokinetics. Blood supply to liver is achieved in two paths. This dual supply characteristic distinguishes the CT enhancement of liver from that of the other organs. The first path is by hepatic artery and to second, by portal vein. However, it is assumed that only gepatic artery can supply blood to hepatocellular carcinoma(HCC) compartment, thus, the difference of contrast enhancement is resulted between normal liver tissue and hepatic tumor. By solving differential equations for each compartment simultaneously using the computer program Matlab, CT contrast-enhancement curves were simulated. The simulated enhancement curves for aortic, hepatic, portal vein, and HCC compartments were compared with the mean enhancement curves from 24 patients exposed to the same protocols as the simulation. These enhancement curves showed a good agreement. Furthermore, we simulated lesion-to-liver curves for various injection protocols, and the effects were analyzed. The variables to be considered in the injection protocol were injection rate, dose, and concentration of contrast material. These data may help to optimize scanning protocols for better diagnosis.

  • The purpose of this study was to examine obstetrical & gynecological health status and body composition for married female immigrants. The participants were 154 immigrant women living in Busan. Data were collected from July 2008 to July 2009 using a questionnaire and a bioelectrical impedance analysis tool (Inbody 720) for analysis of body composition. Most subjects were in the normal range for body composition, but some of those who answered the questionnaire had experienced some gynecological problems such as dysmenorrhea, or irregular menstruation. There was a significant difference in experiences with in vitro fertilization, pregnancy and abortion according to age and in premensturaion syndrome, as well as differences in regulation of menstruation during the past year, leukorrhea odor, experiences in in vitro fertilization, and delivery and breastfeeding according to nationality. There were significant differences in body mass index and waist-hip ratio according to age, as well as differences in percent body fat, body mass index and waist-hip ratio according to nationality. There were also significant differences in body mass index and waist-hip ratio according to period of stay in Korea. Procreative care protocols concerning married female immigrants' characteristics should be developed.

  • As the radiological medical instruments have been competitively developed in recent years, its utilization for the patient treatment has been expanded. The medical examination using the radiation has been gradually increased, so that it is recognized as a significant factor of increasing the radiation exposure. In this study, the recognition about the radiation exposure was analyzed for 555 gynecologic patients in 8 secondary and tertiary medical centers in Gyeongbuk from November 17 to April 19, 2007. The results are followed. There was a significant difference on the recognition for the radiation by age and education (p<0.05), There was the significant difference in the recognition about the radiological instruments by age and occupation (p<0.05), and there was the significant difference in the information identification & analysis by age and occupation (p<0.05). As the result of analyzing a correlation of the radiation's harmfulness, recognition, psychological state and exposure prevention, there was the correlation of 0.572 between the harmfulness and recognition, the correlation of 0.740 between the harmfulness and the psychological state, and the correlation of 0.477 between the harmfulness and the exposure prevention. It was statistically very significant (p<0.01). But, there was no significance with the radiological instrument and information identification (p>0.05). As the result of the study, it could be known that the mental threat factor was more included than the physical threat from the position of gynecologic patients who were sensitive to the radiation. Accordingly, radiological technologist who manages the radiation needs to let the patient or its guardians recognize the degree of physical harmfulness exactly.

  • 백혈병은 조혈계통의 악성 증식성 질환으로서 현재까지 주로 화학약물요법에 의존하고 있는 실정이다. 화학약물요법은 백혈병 세포를 소멸시킬 수 있지만 또한 인체에 여러 가지 독성 반응 및 부작용을 일으키기도 한다. 따라서 중서의결합으로 백혈병 치료에 접근하는 것은 중요한 의미를 갖는다. 중의학에서 소아 백혈병을 치료하는 경우 청열해독법(淸熱解毒法), 부정보허법(扶正補虛法), 활혈화어법(活血化瘀法)을 주로 사용한다. 청열해독법은 백혈병의 조기치료에 주로 활용되는데, 인체의 저항력을 증강시켜 화학약물요법을 실시하는 동안 흔히 나타날 수 있는 감염증상을 예방하는 효과를 얻을 수 있다. 부정보허법(扶正補虛法)은 주로 화학약물요법의 유도 완화기 및 치료효과의 유지를 위하여 활용되는데, 이는 인체의 면역력을 향상시켜 화학약물요법이 인체에 미치는 손상을 경감시킬 수 있다. 활혈화어법(活血化瘀法)은 미세순환을 개선시키는 작용을 하며 골수의 조혈기능을 촉진하고 면역기능을 조절하며 또한 일부 활혈화어제(活血化瘀劑)는 백혈병 세포에 직접적인 억제효과를 보인다. 소아백혈병에 대하여 화학약물요법을 진행하는 동안 중약을 같이 병행하는 경우 다음과 같은 과정으로 나누어 실시할 수 있다. 1. 유도완화치료(화학요법)단계: 이와 같은 치료과정은 대개 화학약물요법으로 인한 극심한 독성반응이나 주작용을 나타내게 되는데, 이 과정에서 중약치료를 병행하면 신속하게 증상을 개선시킬 수 있다. 만약 구토나 설사와 같은 소화계 부작용이 나타나면 화위강역법(和胃降逆法)을 활용하고, 감염 증상이 나타나면 부정(扶正)과 거사법(祛邪法)을 병행할 수 있다. 화학약물요법을 진행한 후 신체가 극도로 허약해지고 골수의 기능이 심하게 억제되는 경우는 주로 부정(扶正)시키는 중약을 사용하면서 익기양혈제(益氣養血劑)를 곁들이고 보조적으로 단삼(丹蔘), 당귀(當歸), 천궁(川芎), 계혈등(鷄血藤) 등과 같은 활혈화어제(活血化瘀劑)를 사용하여 골수의 조혈기능을 회복시킨다. 2. 치료효과의 유지단계: 본 과정에서는 중약치료에 있어서 부정(扶正)과 거사법(祛邪法)을 병행한다. 화학약물요법을 실시하는 동시에 거사제(祛邪劑)를 중용(重用)함으로써 화학약물요법의 효과를 강화시킨다. 화학약물요법이 끝난 뒤 부정(扶正)시키는 약물을 중용(重用)하여 인체의 면역기능을 증강시키고 백혈병세포를 억제시킨다. 3. 치료효과의 유지 및 강화단계: 치료효과의 유지단계에서는 변증논치(辨證論治)의 원칙에 입각하여 항암효과가 있는 중약을 활용할 수 있는데, 예를 들어 백화사설초(白花蛇舌草), 산자고(山慈?), 청대(靑黛), 용규(龍葵) 등을 사용할 수 있고, 육신환(六神丸)을 장기적으로 복용하여도 된다. 소아백혈병 치료에 있어서 중서의결합의 치료법을 활용하는 경우 다음과 같은 내용에 주안점을 둘 수 있다. 화학약물요법을 진행하는 과정에서 중약을 병행하여 투여하는 경우 사진합삼(四診合參)을 근간으로 종합적인 분석을 통하여 병인(病因)을 살피어 치료에 임하도록 한다. 약물의 선택과 처방의 구성은 반드시 변증논치(辨證論治)의 원칙하에 이루어져야 한다. 화학약물요법과 중약치료를 병행하는 과정에서 변증(辨證)과 변병(辨病)이 서로 결합되고 부정(扶正)과 거사법(祛邪法)을 병행하여 활용한다. 정체관(整體觀)에서 출발하여 환자를 관찰하는 동시에 특징적인 증후(證候)에 대한 변증논치(辨證論治)도 중요하며, 또한 백혈병 환자의 유형(類型)이나 임상 혈액검사 소견, 골수의 양상, 화학요법의 진행단계 및 환자의 연령과 체질 등을 충분히 가만하여 종합적인 분석을 토대로 치료법을 선택하여야 중약요법과 화학약물요법의 협동적인 효과를 증폭시키고 백혈병치료에 새로운 전기를 마련할 수 있을 것이다.

  • 최근 초등학생들은 간식은 물론 끼니를 위해서 스스로 식품이나 음식을 선택하고 구매하는 식생활 관리의 주체자가 되고 있다. 본 연구는 초등학생의 간식구매실태와 이에 영향을 미치는 식생태적 요인을 파악하고자, 서울과 충청남도의 대도시, 소도시 및 농촌의 4개 지역의 초등학생 4, 5, 6학년 총 431명(남 223, 여 208)과 그 학부모를 대상으로 간식섭취, PC와 TV 이용도, 학부모의 영양지식과 식태도, 간식구매빈도 등을 설문지 조사를 하였다. 조사대상 초등학생의 평균 신장과 체중은 교육부의 학생 신체검사 결과보다 약간 높거나 비슷하였으나, 조사대상의 30.6%가 저체중이고 10.8%가 비만이었다. 가정의 월 소득은 101-200만원이 가장 많았고(56.3%), 아버지는 대졸 이상이 59.7%, 어머니는 고졸 이상이 55.9%로 가장 많았으며, 어머니는 44.1%가 직업을 갖고 있었다. 학생의 월 용돈은 2,001-5,000원이 31.0%로 가장 많았으며 간식 비는 1일에 500원 미만이 46.0%로 가장 많았다. 간식섭취 빈도는 1일에 1번 섭취가 51.5%로 가장 많았고 간식 구매 시 고려사항은 맛, 가격, 영양가와 유통기한의 순 이었다. 조사대상의 46.9%가 PC통신 또는 인터넷을 사용하였고 사용시간은 1시간 미만이 53.8%로 가장 많았으며, 하루 평균 TV 시청시간은 2~4시간미만이 46.4%로 가장 많았다. 학부모의 평균 영양지식 점수는 13개 문항 중 8.16 $\pm$ 2.16으로서 평균 62.8%의 정답 율을 보였으며, 식 태도 점수는 총 50점 만점에 전체 평균이 43.22$\pm$4.04로서 비교적 양호하였다. 식품별 구매빈도를 보면 1주에 1회 이상으로 나타난 것은 우유, 과자류, 빙과류, 라면, 주스 및 껌의 순 이었고, 햄버거, 피자, 호떡은 한 달에 1회 또는 그 이하로서 가장 낮았다. 과자, 라면, 빙과류의 구매빈도는 가정수입과 아버지와 어머니의 교육수준과 음의 상관 관계를, 학생의 월 용돈, TV 시청시간 및 간식섭취 빈도가 높을수록 와는 양의 상관관계를 보였다. 라면과 탄산음료는 부모의 영양지식이나 식 태도와 음의 상관관계를 나타냈고, 햄버거 구매빈도는 가정수입과 아버지와 어머니의 교육수준이 높을수록 잦았다. 학생의 간식빈도가 높을수록 우유섭취빈도는 낮았으며, 과자, 빙과, 사탕, 닭 꼬치, 감자튀김, 돈까스, 튀김의 구매빈도가 증가하여 간식내용이 영양적으로 양호하지 않음을 알 수 있다. 또한 TV 시청시간이 길수록 간식빈도와 유사한 구매 양상을 나타냈다. PC이용시간이 길수록 과자와 빵의 구매빈도가 낮아지고 껌의 구매빈도가 높아져 흥미롭다. 결론적으로 조사대상 초등학생은 간식 구매시 영양가보다는 맛을 중요시하며, 우유를 제외하면 주로 탄수화물과 당류식품의 구매빈도가 높다. 또한 가정 소득, 부모 교육수준과 영양지식, TV시청시간, 학생의 간식 비와 간식빈도 등 환경요인들이 식품구매에 영향을 주었다. 따라서 영양사를 중심으로 간식 선택의 중요성과 식품 구매 원칙에 대한 체계적인 영양교육을 학생과 아울러 학부모에게도 실시하여 초등학생의 바른 간식 구매능력을 향상시켜야 할 것이다.
