The purpose of this study was to quantitatively examine the physiological and psychological effects of a waterscape facility in an interior landscape space. Data were collected as participants under stress relaxed in either an interior space with greenery(Type G) or an interior space with a waterscape facility(Type W). The participants relaxing in the Type W space showed significantly decreased systolic and diastolic blood pressures, and an impression evaluation by the SD method indicated that their impressions were expressed in more positive terms, such as 'vigor', 'dynamism', 'pleasantness', and 'vitality'; when compared to participants relaxing in the Type G space. A POMS analysis showed waterscape elements influenced participants' psychological mood states by decreasing tension and fatigue, but increasing vitality. Introduction of waterscape facilities into interior landscape spaces could therefore provide stressed individuals with health benefits, including decreased blood pressure and positively changed psychological mood states.

모든 인간은 빛과 함께 할 때, 보다 편안함을 느낄 수 있으며, 안정된 마음으로 아름다움과 행복을 추구하려는 본능을 가지게 된다. 더구나 태양빛의 스펙트럼 특성과 하루의 빛의 리듬, 계절적인 빛의 변화에 모든 동식물들은 다양한 생리적 반응을 일으키도록 되어 있는 만큼 색온도의 심적인 효과를 조명계획에 의도적으로 사용하는 것은 공간을 한층 더 쾌적하게 만드는 수단이 될 수 있다. 이런 이유로 현대인들이 가장 많은 시간을 보내는 실내 공간에서 감성조명이 필요하다. 이미 조명은 빛을 발하는 단순 기능에서 벗어나 생활과 사회 전 분야에 걸쳐 하나의 예술문화로 자리매김했다. 감성조명은 이러한 시대 요구에 부응하고, Well-Being을 추구하는 현대인들에게 꼭 필요한 기술이다.

Stresses from desolate urban environments cause illnesses and worsen health conditions of urban residents, while natural environments have a positive influence on human. Natural healing programs such as forest therapy and horticultural therapy can be differentiated by the characteristic of activity space. However, previous studies of healing programs have focused on either forest therapy or horticulture therapy and there is a limit to comprehending the effects of adopting and connecting various healing programs. This study compares and analyzes the physiological and psychological effects of forest therapy and horticultural therapy to identify the effects and differences by types of healing programs. The before and after effects of horticultural therapy and forest therapy are measured by experiment and survey for 5 days with 5 subjects in each program. For physiological reaction, blood pressure, pulse, and cortisol levels are measured and the profile of moods states(POMS) is used to measure psychological reaction. Collected data are analyzed with the analysis of variance(ANOVA) and Paired-Sample T-test in SPSS 18.0. The results of this study are as follows: 1) forest therapy and horticultural therapy show positive effects in physiological and physiological aspects, 2) forest therapy is more effective than horticultural therapy in physiological relaxation and stress mitigation, 3) horticultural therapy has a tendency to alleviate depression more effectively than forest therapy. In conclusion, this study contributes to providing fundamental information for the development of healing programs and design guidelines for healing spaces through identifying the characteristics of each healing program.

25만 여종에 달하는 지구상의 식물은 생물권의 무수한 환경변화 속에서 종을 유지할 수 있도록 다양한 유전적인 진화를 통하여 지구상에 정착하였다. 이들 식물이 생육하고 있는 기상환경은 매우 다양하며, 생장과정에서 수많은 환경변화를 시간적ㆍ공간적으로 경험하게 된다. 생육 환경이 변화하면 식물의 형능적, 생리적, 생합성적 특성이 변화하는 반응이 나타난다. (중략)

This study examined temporal and spatial patterns of bioclimatic perceived sultriness in South Korea by analyzing the climatology of heat index calculated from ambient temperature and relative humidity for the period of 26 years (1973-1998). As results, spatially, bioclimatic sultriness above all thresholds frequently occurred mainly in the central western inner area, the southwestern inner area, and the southeastern inner area of South Korea. Especially, Miryang in the southeastern inner area of South Korea was proved to be, bioclimatically, the sultriest area in South Korea that has recorded frequent high heat index. Temporally, frequency of sultriness in the contiguous South Korea significantly increased in the 1990s. Specifically, In 1994, frequencies of heat index exceeding each threshold was the highest all over South Korea. Normally, the sultriness with high heat index exceeding 40.6$^{circ}C$ occurred mainly for the period of between the end of July generally after Summer Changma and the beginning of August before another small rainy season of years. These temporal-spatial distributions of bioclimatic sultriness in South Korea showed various patterns regionally, affected by physical and anthropogenic climatic factors such as topography, latitude, altitude, water bodies or aforestration, urbanization, and industrialization as well as movements of large-scale air masses.

주거공간 내 조명환경은 인간의 심리적, 생리적 기능에 많은 영향을 주는 요소임에도 불구하고 현재의 조명환경은 사용자의 상황과 공간 특성을 고려하지 않은 단일화된 형태로 제공하고 있다. 또한 인간의 심리에 영향을 미치는 조명의 요소로는 빛의 색온도, 조도, 색상, 눈부심, 균제도 등이 있으나 대다수의 조명은 밝은 조도에만 초점을 맞추어 사람의 눈부심을 자극하는 조명이 대부분을 차지하고 있다. 따라서 사용자에게 좀 더 편안하고 쾌적한 조명환경을 제공하기 위해서는 사용자의 행동, 심리적 상황 등에 따라 조명의 색온도, 조도 그리고 색상이 고려된 상황조명 서비스가 필요하다. 본 논문에서는 사용자의 재실여부와 행위 등의 상황을 인지하고 이에 따라 조명의 On/Off, 색온도, 조도, 색상의 조명환경을 제공하는 상황인지 기반의 LED 조명 제어시스템을 제안한다.

본 연구에서는 미래 감성실내 공간색채에 대한 연구로 심리설문반응과 생리 신호 분석을 통하여 감성색채데이터 분석에 목적을 두었다. 생리신호반응 분석 중 뇌파측정과 7점 척도 SD 스케일법을 이용한 설문조사를 실시하여, 정상적인 감성어휘와 정량적인 생리신호 결과의 상호관계를 분석하였다. 기존의 직관적이며 주관적인 색채 배색디자인과 심리분석의 색채연구결과에 비해 본 연구는 객관적이며 과학적인 방법 및 주관적인 감성어휘를 연결짓는 것으로 연구의 의의를 두었다. 이러한 연구는 감성에 미리 반응하는 감성 지능형 환경디자인에 중요한 페이지로 활용될 수 있을 뿐만 아니라 현대인의 건강에 대한 관심 증가에 따라 건강 증진 환경디자인에 도움을 줄 수 있는 색채 배색을 제안할 수 있다.

Purpose: This study was to investigate peripheral vision and provide people with macular degeneration with a guideline for eccentric viewing training. Methods: 30 adult subjects with normal vision took part in this study. The lateral area of $20^{\circ}$ eccentricity from the fovea of right eye was only used to measure the physiological summation. The target was sinusoidal vertical gratings within a circular aperture. The critical points in spatial and temporal summation was found to compare each other for 0.7 cpd and 3.0 cpd, respectively. Results: Critical duration and contrast sensitivity for 0.7 cpd were 540 ms and 1.1, and 315 ms and 0.98 for 3.0 cpd respectively. The critical degrees and contrast sensitivity for 0.7 cpd were $11.3^{\circ}$ and 2.8, and $5^{\circ}$ and 2.63 for 3.0 cpd respectively. Conclusions: The critical point in peripheral vision reaches relatively faster than the one in central vision. It is recommended to train the peripheral retina under the lower spatial frequency more frequently for a short time than constantly for a long time.

욕실은 인간의 가장 기본적인 생리 욕구를 해결하는 곳이며 건축물 등의 구조물에 설치되는 기계설비 중급 배수 및 위생 설비가 가장 집약적으로 들어가는 곳 중 하나이다. 욕실은 위생이라는 기능적 측면에서 매우 중요한 공간이지만 인간의 자아 안정을 위한 정신적 측면도 함께 고려되는 복합적 기능을 가진 생활 필수공간이다. 최근들어 욕실 트렌드는 펜트하우스급에서나 꿈꾸던 고급 이미지를 벗어던지고, 친환경 웰빙 흐름에 맞춰 절수 제품과 위생 청결 강화 제품이 인기를 끌고 있다. 본지는 점점 진화하고 있는 욕실 환경에 대해 알아 본다.

In the case of excessively worn dentition, there is often insufficient space for the prosthesis, and if physiologically acceptable, the prosthesis can be fabricated by increasing the vertical dimension of occlusion. Various methods have been introduced to determine the vertical dimension of occlusion. Clinicians have to choose a method that can comfort the patient among several methods. A removable appliance can be used as a reversible method to ensure that the determined vertical dimension of occlusion does not cause physiological problems. When making impressions of many teeth, it is often difficult to make accurate impressions at once. In this case, after making an accurate impression of the individual teeth, a transfer coping was made and a pickup impression was taken in the oral cavity to create a master cast. In this case, a fixed partial denture was fabricated and full mouth rehabilitation was performed by increasing the vertical dimension of occlusion in a patient with excessively worn dentition and lack of space for restoration. As a result of follow-up of the patient for 7 years, satisfactory results were obtained both esthetically and functionally.
