  • 이 연구는 성인 남녀 462명을 대상으로 사전 설문검사를 통해 성별, 손잡이, 혈액형, 연령 등의 개인별 특성 집단과 다중지능 유형별 점수를 분류하였다. 그런 다음 뇌파측정시스템을 이용하여 전전두엽 부위인 Fp1과 Fp2 부위에 측정 전극을 부착하고 무자극 상태와 순수한 Pink noise 청각자극 상태에서의 집중력의 변화와 다중지능과의 관계를 알아보고자 하였다. 공분산분석 결과, 무자극에 비해 Pink noise 자극 시 대상자 전체의 평균 집중력이 유의하게 높게 나타났다. 개인별 특성에서는 남녀 성별을 제외한 왼손잡이, A형, 30대 집단에서 집중력이 유의하게 높게 나타났다. 그리고 무자극에 비해 Pink noise 상태의 집중력은 공간적 지능과의 관계가 더욱 강화되었고, 음악적 지능과는 음적 상관관계를 형성하였다. 이러한 결과는 집중력 향상을 위한 Pink noise 활용 시 개인별 특성을 반영해야할 필요성이 있음을 시사하였다.

  • 본 연구는 화이트 노이즈와 핑크노이즈가 뇌에 미치는 영향을 증명하기 위해 확률 공명(stochastic resonance, SR) 현상으로 확인하고자 한다. 피실험자 20명(여 10, 평균나이 $23.3{\pm}2.14$)을 대상으로 각각 노이즈 청각 자극을 제시하고 뇌파를 측정했으며, 주파수 분석을 통해 뇌 활성도를 확인했다. 분석결과, 레퍼런스, 화이트 노이즈 보다 핑크 노이즈 자극 시 alpha, low beta 대역이 증가하고, high beta 대역이 감소했다. 또한 전두엽과 측두엽 지점에서 유의하게 증가했으며, 뇌 활성도가 우반구에서 유의하게 우세한 패턴을 확인했다. 이 결과는 노이즈의 새로운 긍정적인 활용성 모색과 청각영역에 관한 뇌신경과학분야의 기초 연구로써 활용 가능할 것으로 사료된다.

  • The Purpose of this study is to examine closely the causes influenced upon the comfort and recovery of the woman delivered of a child in the hospital at the same time to understand environmental status of hospitals in order to promote mother's health recovery, and to improve hospital environment by emphasizing the meaning of environment and health before the medical staff and hospital administrative authority. In the method of servery of the research, 165 post paestum patients have been randomly selected who were accommodated and delivered their babies at OB(obstetric ) & GY (Gynecologic) unit the 7 general hospitals for the period of 6 December 1976 through 17 December 1976. As for the survey, it has been used of Questionnaire where we have 65 items in the respect of personal environment in the hospital such as trusting nurse, ability, reliability, kindness and etiquette of nurse and tile character of nurse the relationship with patients the other respect of physical environment included 9f temperature, moisture. air-ventilation lightening noise, cleanness. facilities, and the third realm being of mother's hearth ground to have the following conclusion 1. The feature of the collected personnel they are from OB or GY sects of from OB unit of the other 5 hospitals except the two general hospitals of the college or school Otherwise the rate of the patients to nurses would be 9 : 1. As for the nurses'ground it would be appeared of 20-25 years of age as the 76%. either 3 year course or 4 year course in the education would be each 50% and less than 2 year experience case would record as of 60 %. In the respect of hospital physical environmental status, there we have two hospitals without any thermometers, on the other han4 nowhere there's hygrometer, otherwise, the lightening is normal or over than normal As for the structure of noise protection the corridors're, generally speaking worse than rooms, nerver hueless, there's no ventilating system in the hospitals. The rooms'repainted in white and yellow, light green white, or green color. The patient's clothing were in green pink blue, light green or in white co for. There're not anything special in both decoration and equipments. Most of them used tall beds except in one hospital 2. To the extent of perception of patient's hatch 9round and hospital environment it is presented that they perceived nurse's ability in highest in total human variable, though perceived kindness or etiquette in the lowest otherwise, comparatively high in total average. 3. In the respect of physical environment it is highest perceived of lightening terms, otherwise, lowest perceived of air ventilation and total average became lowest than the one of the original record 4. To ages, in the respect of hatch ground rather old aged mother than the younger one has perceived that nurse would be trusting, in good service character, able, at the same time, liable, Otherwise, in physical environment regardless of age, they perceived lightening in high and remarkably lower in ventilation As a result of the examination of the difference in hospital environment to each age it is appeared of statistical difference at 5% level of ability in the personal environment otherwise little difference as for physical environment 5. In the respect of perceiving level to educational standard it is highly perceived of personal environment for higher ranking group rather than lower group in the educational standard. In case of physical environment it is highly perceived for lower level group rather than higher level group in educational background. The variables which have statistical significance at 5% level are from trusting kindness, etiquette and total kindness, etiquette and total all significance at 5% level are from trusting, kindness, etiquette and total human environment variable in personal environment, otherwise, there's little difference in the physical environment. 6. The perceiving level due to times of admission and accommodation at the hospital would be cleared out as gradual higher perception both physical and personal environment in the hospital. At 5% significant level of the ventilation condition in physical environmental variable it is presented of meaningful difference otherwise, there we have little difference both in Personal variable and other one. 7. In accordance with living standard, the perception degree of personal environment in tee hospital would be inclined to increase to higher living standard on the other hand, in case of the physical environment, the perception level world increase to lower living standard At 5 % level, the trustuariable and total scores in the personal eicuironmectal variable there appeared a meaningful/ significant difference otherwise, there presented little difference both in physical environmental and other variable to the living standard 8. Pertaining to family unit, the mother of an independent family unit perceived highly in all respect of the personal and the physical environment in the hospital rather than the woman of succeeding family unit. At 5 % level there appeared a difference in the respect of kindness and etiquette both in personal environment variable, on the other hand, there hardly marked a difference between other variable and physical environmental one. 9. The degree of perception to comforting level has little connection with a statistical difference the age, educational level hospital admitting times, living standard or family unit. 10. The most effective variable to mother's comforting level will be nurse's ability, reliability, trusting manner, and total physical environment variable in order.
