Purpose: The purpose of this study was to measure the effects of aroma inhalation on fatigue and quality of sleep of postpartum mothers. Method: The study design was a non-equivalent control group pre-post design. 51 Postpartum mothers were assigned either to a control group or to an experimental group that was exposed to aromas through inhalation for 6 days. Subjects in the experimental group were instructed to wear a necklace filled with Lavender and Eucalyptus oil from 2:00 PM to 8:00 PM every day. Fatigue was measured using the Rhoten Fatigue Scale. Sleep duration, night arousal frequency and sleep satisfaction were used to assess the quality of sleep. Result: There was a significant difference in the score of fatigue following the treatment between the experimental and control groups (t=-2.79 p=.00). However, there was no significant difference in sleep duration, frequency of night arousal and sleep satisfaction following aroma inhalation between two groups. Conclusion: This intervention appears to be effective in reducing the fatigue in postpartum mothers.

The purpose of this study is to provide definition of proprioception, foundations and roles of neuroanatomy, and systemical review of proprioceptive activities in sensory integration intervention. Proprioception exists in muscle, ligaments, joints and skin and it plays important role in controling body movements and interacting with environment during child development. Proprioception interacting with tactile and vestibular systems contributes to the change of muscle tone, postural control, refinements of planning and praxis. Children who are deficit in proprioceptive processing would seek hypo-responsive proprioceptive input or avoid hyperactive one. Outcome of poor proprioceptive input would cause the problems of praxis and postural control. Because proprioception provides information about the position and movement of body and limb it is important for development of body scheme and motor planning. It also influences the arousal and emotional tone. Sensory integration intervention which provides rich proprioceptive activities will improve the level of arousal and enhance motor planning.

Background: Bus driving is a mentally demanding activity that requires prolonged attention to ensure safety. The aim of the study was to assess mental fatigue caused by driving a public bus and to find a profile of workers at higher risk. Methods: We evaluated changes of critical flicker fusion (CFF) (index of central arousal) and heart rate variability (HRV) (index of autonomic balance) in a 6-hour driving shift on a real route, in 31 professional bus drivers, and we tested the influence of personal factors such as sleep quality, BMI, and age. Paired t-test was used to test differences of CFF and HRV between both initial and final phase of driving, while multiple linear regression tested the influence of personal variables on the indexes of mental fatigue. Results: Results showed that CFF significantly decreased after 6 hours of bus driving (41.91 Hz, sd 3.31 vs. 41.15 Hz, sd 3.15; p = 0.041), and heart rate significantly decreased in the final phase of driving, with respect to the initial phase (85 vs. 78 bpm, p = 0.027). Increasing age (beta = -0.729, p = 0.022), risk of obstructive sleep apnea syndrome (beta = -0.530, p = 0.04), and diurnal sleepiness (beta = -0.406, p = 0.017) showed a significant effect on influencing mental fatigue. Conclusion: Elderly drivers at higher risk of sleep disorders are more prone to mental fatigue, when exposed to driving activity. Monitoring indexes of central arousal and autonomic balance, coupled with the use of structured questionnaires can represent a useful strategy to detect profile of workers at higher risk of mental fatigue in such duty.

몰입은 관람객이 콘텐츠를 관람할 때 관람객들이 콘텐츠에 몰두하고 있는 심리적 상태를 의미하는 것으로, 관람객의 몰입경험은 콘텐츠의 만족도에 긍정적인 영향을 미친다. 따라서 공연 같은 콘텐츠를 제공하는 기업들은 콘텐츠의 흥행을 위해 관람객의 몰입도를 측정하는 것은 매우 중요하다. 설문 등의 표본조사 방법을 통해 관람객의 몰입도를 측정 연구는 방송분야 등 에서 널리 사용되고 있다. 이러한 몰입도 측정방법은 콘텐츠 관람 이후 설문을 실시하기 때문에 몰입도를 실시간으로 측정할 수 없을 뿐만 아니라 몰입도 측정의 정확성이 저하되는 문제 등이 있다. 이러한 문제를 해결하기 위하여 생리적 반응이나 얼굴 표정 분석, 그리고 움직임 관찰 방법 등을 이용하여 몰입도를 측정하는 연구가 수행되고 있다. 생체 신호를 이용하여 몰입도를 측정하는 연구의 경우, 1인을 대상으로 생체신호를 측정할 뿐만 아니라, 많은 데이터 처리 시간과 비용이 소모되는 단점이 있어 많은 관람객이 관람하는 공연장에 적용하기에는 한계가 있다. 얼굴 표정인식 통해 몰입도를 측정하는 경우도 1인을 대상으로 하고 있으며, 밝은 조명의 실험실 환경에서만 가능하다는 단점이 존재한다. 또한 관람객들의 움직인 동기화를 이용하여 몰입도를 특정한 연구는 다중관객을 대상으로 하였지만, 이는 실험실 환경에 한정하여 적용된 사례이다. 따라서 본 연구에서는 공연장, 시사회관 등 많은 관람객들이 콘텐츠를 관람하는 실제 환경에서 다중관람객이 다중몰입도의 정량적 평가를 위한 시스템을 설계하고 개발하였다. 제안된 시스템은 외부장치, 서버, 내부장치 등의 3부분으로 구성되어 있다. 서울시 마포구 상암동에 위치한 DMC 홍보관에 상설 전시장으로 운영하고 있으며, 관람객들을 대상으로 데이터를 획득하고 있다. 제안하고 있는 시스템을 활용하면 콘텐츠의 어느 구간에서 관객들이 몰입을 하고 있는지, 어느 구간에서 몰입을 하고 있지 못한지 분석가능하기 때문에, 향후 콘텐츠 제작 및 마케팅에 유용하게 활용할 수 있을 것으로 기대된다.

The selection of anesthetic agent is important in preclinical studies, since each agent affects the systemic hemodynamics in different ways. For that reason, we hypothesized that different anesthetic agents will result in different vaginal hemodynamic response and temperature during sexual arousal, in an animal model. To validate the hypothesis, animal experiments were performed using female rats with two anesthetic agents widely used in preclinical studies: ketamine and isoflurane. Our previously developed near-infrared-spectroscopy-based probe was used to measure the changes of oxyhemoglobin (OHb), deoxyhemoglobin (RHb), and total hemoglobin (THb) concentrations along with temperature from the animal vaginal wall. As a control, saline was administered to both isoflurane- and ketamine-anesthetized animals, and did not show any significant changes in OHb, RHb, THb, or temperature. However, an administration of apomorphine (APO, 80 ㎍/kg) induced increases of OHb (63 ± 28 μM/DPF), RHb (35 ± 20 μM/DPF), and THb (98 ± 49 μM/DPF) in ketamine-anesthetized animals, while decreases of OHb (52 ± 76 μM/DPF) and THb (38 ± 30 μM/DPF) and an increase of RHb (28 ± 51 μM/DPF) were found in isoflurane-anesthetized animals. The vaginal temperature decreased from the baseline in both ketamine-(0.42℃) and isoflurane-(1.22℃)anesthetized animals. These results confirmed our hypothesis, and suggest that a preclinical study monitoring hemodynamic responses under anesthesia should employ an appropriate anesthetic agent for the study.

The purposes of this review are that 1) what is the the concept of motor control, 2) what is the content of motor control assessment, and 3) which instruments or scales are used in clinical setting. Motor control is defined broadly the control of both movement and posture. And motor control focuses on understanding the control of movement already acquired. The purposes of assessment are screening, placement to apprpriate treatment program, program plan, evaluation, and progress assessment for individuals. The content of motor control assessment is included not only fexibility, tone, reflex & reaction, muscle strength, movement pattern, balance, gait, and functional ability, but also cognition, arousal, sensation, and perception. There ars many kinds of instruments or scales for assessing motor ability. Most of materials are tested the validity and reliability. But Korea has not own instrument for assessing motor ability. Therefore, Korea needs to develop the assessing tools for motor ability.

Purpose: The purpose of this study was to evaluate the effectiveness of the Permission, Limited Information, Specific Suggestions, Intensive Therapy (PLISSIT) model sexual program on female sexual function for women with gynecologic cancer. Methods: The integrative 6-hr (two hours per session) program reflecting physical and psychosocial aspects of women's sexuality was developed based on Annon's PLISSIT model. Participants were 61 women with cervical, ovarian, or endometrial cancer. Of them, 29 were assigned to the experimental group and 32 to the control group. The women completed the Female Sexual Function Index (FSFI) including sexual desire, arousal, lubrication, orgasm, satisfaction, and pain. Independent t-test and repeated measured ANOVA were used to test the effectiveness of the program. Results: Significant group differences were found on FSFI sub-domain scores including sexual desire, arousal, lubrication, orgasm, and satisfaction but not pain. Significant time differences were found on all domains except for pain in the experimental group repeated measured ANOVA. Conclusion: The results indicate that the three-week PLISSIT model sexual program is effective in increasing sexual function for women with gynecologic cancer. Nurses may contribute to improving women's sexual function by utilizing the program. Strategies to relieve sexual pain need to be considered for greater effectiveness of the program.

Shihogayonggolmoryo-tang (ST) is a Korean medical herb cocktail which has been used to treat anxiety induced insomnia. In this study, we will examine sleep-promoting and anti-anxiety effects of ST, and investigate its mechanism. ICR mice were divided into three groups for the first examination : control group (n=11), ST50 group (50 mg/kg, po, n=11), ST200 group (200 mg/kg, po, n=11). Sleep-promoting effect was confirmed by measuring the sleeping duration time and sleeping onset time after thiopental sodium treatment (50 mg/kg, ip). ICR mice were divided into five groups for the second examination : control group (n=11), ST200 group (200 mg/kg, po, n=11), ST200+Flumazenil group (ST 200 mg/kg, po, flumazenil 0.3 mg/kg, ip, n=11), diazepam group (1 mg/kg, ip, n=11), diazepam+flumazenil group (diazepam 1 mg/kg, ip, Flumazenil 0.3 mg/kg, ip, n=11). Anxiety behavior and sleep-promoting effect was confirmed by open field test and measuring the sleeping duration time and sleeping onset time. Expression levels of c-fos in tuberomammillary nucleus (TMN) and ventrolateral preoptic nucleus (VLPO) were analyzed by immunohistochemistry. ST treated group showed significantly decreased anxiety behavior and enhanced sleeping duration time and sleeping onset time concentration dependently. The expression of c-fos was significantly upregulated in VLPO as sleep-inducing center and TMN as downregulated in arousal center by ST treatment. In addition, all effects of ST were reversed by flumazenil. Our results suggest that ST has sleep-promoting and anti-anxiety effects through regulating arousal center (TMN) and sleep-inducing center (VLPO).
