Insomnia is one of the most common clinical symptom those almost patients with neuropsychiatric disorder complain. and the most common cause of insomnia in neuropsychiatric disorder is the major depressive disorder. We experienced a 59 year-old male who complained of recurrent insomnia in spite of taking medicines(nervines, antidepressants, etc,) during 30 years. We had given herbal medicine, acupuncture treatment and aroma therapy with continuing medications. The patient had several sypmtoms as anxiety, agitation, feeling thirsty, chronic constipation, and etc. beside the insomnia. After the patient took the herbal medicine, especially Sam-Hwang-Sa-Sim-Tang, he could have a sound sleep and be relaxed. In this case, we concluded that oriental medical treatment can be an effective remedy of chronic insomnia that responds to neuropsychiatric medications incompletely and Sam-Hwang-Sa-Sim-Tang is effective to a kind of insomnia with agitation, anxiety, thirsty, constipation, and etc.

Background: To refine facial transplantation techniques and achieve sound results, it is essential to develop a suitable animal model. Rat is a small animal and has many advantages over other animals that have been used as transplantation models. The purpose of this study was to describe a rat hemifacial transplantation model and to verify its convenience and reproducibility. Methods: Animals used in this study were Lewis rats (recipients) and Lewis-Brown Norway rats (donors). Nine transplantations were performed, requiring 18 animals. The hemifacial flap that included the ipsilateral ear was harvested based on the unilateral common carotid artery and external jugular vein and was transferred as a single unit. Cyclosporine A therapy was initiated 24 hours after transplantation and lasted for 2 weeks. Signs of rejection responses were evaluated daily. Results: The mean transplantation time was 1 hour 20 minutes. The anatomy of common carotid artery and external jugular vein was consistent, and the vessel size was appropriate for anastomosis. Six of nine allografts remained good viable without vascular problems at the conclusion of study (postoperative 2 weeks). Conclusion: The rat hemifacial transplantation model is suitable as a standard transplantation training model.

This paper is based on our comments and proposed amendments to the documents, Annex A, Phantom for determining Maximum Depth of Penetration, and Annex B, Local Dynamic Range Using Acoustical Test Objects 87/400/CDV. IEC 61391-2 Ed. 1.0 200X, prepared by IEC technical Committee 87; Ultrasonics. The documents are concerned with the influence of microstructure of reference target material on the ultrasonic backscattering. Previous works on the attenuation due to backreflection and backscattering of reference target materials are reviewed. The drawback to the use of ungraded stainless steel and metallic materials without microstructural data such as, crystal structure, basic acoustic data of sound velocity and attenuation, grain size, roughness and elastic constants has been discussed. The analysis suggested that the insightful conclusion can be made by differentiating the influence arising from target size and microstructure on the backscattering measurements. The microstructural parameters are associated with physical, geometrical, acoustical and mechanical origins of variation with frequency. Further clarification of such a diverse source mechanisms for ultrasonic backscattering would make the target material and its application for medical diagnosis and therapy simpler and more reliable.

The purpose of this study was to find out the effects of five senses activities in forests on the reduction or mitigation of daily stress using various forest healing factors such as water, sunlight, topography, phytoncide, landscape, sound, fragrance, etc. The subjects of this study were 40 young children aged 5 in an early childhood education institution located in Cheongju. The children were divided into two groups: 20 in the experimental group and 20 in the control group. The experimental group participated in the program of five senses activities in the forest in total of 12 sessions (1-2 sessions a week), with each session lasting 60 minutes from May 8 to June 16, 2017. The control group, who did not participate in the five senses activities in the forest, participated in the Nuri Curriculum operated by the educational institution. Before and after the program, tests to measure daily stress in three different situations (encountering blame-aggression situation, experiencing anxiety-frustration, and losing self-respect) were conducted on young children and the data were analyzed using SPSS 21.0. As a result, daily stress of the young children decreased in all three situations with statistical significance. Through the five senses activities in the forest, young children could feel the nature by observing and exploring it in the forest, so which reduced their daily stress compared to the activities carried out in the classroom.

The purpose of the study is to analyze the changes of the heart rate, hand function, and health related quality of life of the people with intellectual disability through the increase of the auditory stimulation. The subjects were 16 people with intellectual disability. The increase of the auditory stimulation was modulated through the music sound and the intensity was consisted of 60dB, 65dB and 70dB. The wist heart rate and blood pressure monitor was used to measure the heart rate during the application of the auditory stimulation increase. The hand function of right and left hand was measured by the Purdue pegboard. Health related of quality of life was measured by the short form-8 health survey. As the results, the increase of the heart rate was showed by the increase of the auditory stimulation and the decrease of the hand function and health related quality of life was showed. For these, the increase of the auditory stimulation acts as a psychological distress, thereby the increase of the heart rate and the reduction of the hand function and health relate quality of life showed. Thus, to decrease of the heart rate and increase the hand function and the health related quality of life of the people with intellectual disability, the intensity of the auditory stimulation should be considered in the environmental stimulation.

Although many studies have been conducted on techniques and effects that can be applied to forest meditation in domestic forest healing meditation research, there has been little research on the space where forest meditation takes place. Nevertheless, a meditation space is not just a place concept but a forest environment element responsible for the healing function of a forest, i.e., a place containing healing factors, and can be an essential clue to the healing mechanism. Therefore, to determine whether a healing forest meditation space is suitable for meditation, this study selected the attribute items of the meditation space using the Delphi expert survey and then surveyed the user satisfaction of the healing forest meditation space using the IPA (Importance Performance Analysis) technique. The survey was conducted from August to November 2022, targeting 315 adults who used the forest meditation space at the National Center for Forest Therapy, the Saneum Healing Forest, and the Jathyanggi Pureunsup Arboretum in Gyeonggi Province. The result of the IPA analysis showed the average satisfaction with the forest meditation space was relatively high at 4.33 points on a 5-point Likert scale (4.33 points for the National Center for Forest Therapy, 4.34 points for the Saneum Healing Forest, and 4.37 points for the Jathyanggi Pureunsup Arboretum), indicating that the three healing forest meditation spaces were suitable for forest meditation. Satisfaction with the "Sounds of nature" was high in all three forests. On the other hand, all three forests showed a relatively low satisfaction with "Quietness," indicating it to be a priority problem to be addressed. Also, an open-ended questionnaire survey showed that the mediation space's natural elements, such as natural sounds, scenery, air, forest spaces, and scents, had a higher positive impact on meditation satisfaction than artificial elements, such as facilities. Therefore, it is essential to secure sound resources such as the sound of water and birds around the meditation space, and it is also necessary to consider ways to create a meditation forest in an independent area to avoid encounters with visitors and allow only participants in the forest healing meditation program to enter to increase satisfaction with forest meditation.
