'낭만' 하면 떠오르는 나라 프랑스에서도 손꼽히는 지중해 최대의 휴양 도시, 니스! 리비에라의 여왕이란 말이 있을 정도로 니스는 유럽인들이 최고로 선호하는 휴양지 중 하나다. 에메랄드빛 바다와 청명한 하늘, 한겨울에도 영상 10℃를 넘는 기온, 양호한 자연 환경, 아름다운 경치로 인해 니스에는 사시사철 관광객이 몰려든다.

오늘날 $\ulcorner$장식적 의미$\lrcorner$ 로서 사물의 성격을 표현하는 디자인 경향이 있다. 가끔 열악한 제조환경이나 기술적 빈곤은 장식의 과다현상으로 나타난다. 하지만 장식은 단순히 디자인자체를 꾸미기 위해 이용되기보다는 재료나 기능에 관련된 의미나 구조로부터 발생되어 진다. 그래서 사물에 적합한 재료와 기능을 반영시킴으로서 디자인의 시작이 가능해 진다. (중략)

Purpose: This study aimed at improving the indoor environment of the office building by measuring the indoor environment and conducting a survey. Method: The measurement was conducted from January 13 to March 16 in 2012, targeting 44 sites in same office building located in Seoul, South Korea. The lists of measurement such as dry-blub temperature, relative humidity, formaldehyde (HCHO), asbestos, carbon monoxide (CO), carbon dioxide (CO2), volatile organic compounds (VOCs) and particle pollution (PM10) were measured. In addition, illuminance which belongs to light environment and noise in sound[acoustical] environment were measured respectively. Result: The buildings showed overall pleasant conditions. In terms of the thermal, air, sound, and visual environment, each measurements were satisfied with the requirements in standard, within pleasant ranges, except several sites. However, the survey results were revealed that the office workers were mostly dissatisfied with their indoor environment. Given that the measured values were mostly within standards, the results of survey might have resulted from a compensation mentality biased toward the subjects in psychological terms.

Melatonin hormone involved in human's circadian rhythm adjustment sensitively responds to light's specific short wavelength ratio. A shift worker's circadian rhythm disturbance and sleep disorder are caused by the existing lighting conditions, whose short wavelength ratio is fixed. The life pattern of a shift worker changes irregularly because of irregular working hours and the same lighting environment; thus, his/her concentration is reduced. For such a reason, negative effects ensue to the detriment of healthy everyday life, including a high risk of accidents or having unsound sleep after leaving work. A smartphone-based wavelength control LED lighting system that targets shift workers and that can easily measure and control lighting suitable for wake-sleep cycle, according to working hours and closing hours, is proposed in this paper. First, after the light characteristics of LED lighting that changes depending on light control ratio are measured through the color sensor installed on the smartphone and the externally-linked Mini-Spectrometer, they are stored in the database. Based on the stored optical characteristics data, the measurement module and light control module are implemented. Lighting is offered using a control ratio having the maximum rate of short wavelength in consideration of the target illuminance, classified according to work type by identifying working hours as time when waking is required for shift workers. After a shift work leaves work, the amount of lighting is varied, using a control ratio having a minimum short wavelength rate so that a shift worker can enter the sleep state naturally.

This study is a randomized controlled trial to compare the effects of light therapy on stress, depression, sleep quality and quality of life in middle-aged women. The participants of this study were 56 middle-aged women who worked at the same office. Data collection period was from August 26 to September 13 for the control group and from September 16 to October 4 for the experimental group. Subjective stress, depression, quality of sleep and quality of life in middle-aged women were measured by Numeric Rating Scale (NRS), Center for Epidemiology studies of scale (CES-D), Verran & Synder-Halpern Sleep scale (VHS) and WHO Quality of Life Scale Abbreviated Version (WHOQOL-BREF). Stress index was measured using a Canopy9 RSA (IEMBIO, Gangwondo, Korea) equipment. The data were analyzed by mean, standard deviation, real number and percentage, χ²-test, t-test, repeated measures ANOVA and ANCOVA using IBM SPSS Statistics version 25.0. The results showed that the experimental group applying light therapy had significantly lower subjective stress (F=6.30, p<.001) and higher quality of life (F=2.80, p=.049) than the control group, There was no difference in objective stress index, depression, and sleep quality. As a result, light therapy is partially effective in subjective stress and quality of life for middle-aged women, and further research is needed on middle-aged women working in work environments with limited light exposure.

Esperpento denotes a literary style in Spanish literature first established by Spanish author Ramón María del Valle Inclán that uses distorted descriptions of reality in order to criticize society. And esperpento's narrative strategy is similar in many ways to Mikhail Bakhtin's carnivalism. Especially Valle Inclán's first esperpentic theatre, Luces de Bohemia contained various carnivalistic elements of Bakhtin. The various techniques of Valle Inclán's esperpento used in Luces de Bohemia can be explained by Bachchin's carnivalist techniques. Therefore, this paper aims to re-examine the esperpentic techniques in Luces de Bohemia of Valle Inclán in terms of Bakhchin's carnivalism. Because the esperpentic tecniques of this play pursue the subversion of power or authority through the carnivalistic aspects such as polyphony, subversion of seriousness, parody, grotesque realism, plaza, ambivalence, anomalous structure of space, time and plot, etc. Esperpento and carnivalism serve as a tool to interpret the social reality, beyond criticism and satire of Spanish society. The characters act passively on all the external factors that determine human destiny, rather than actively carving their own destiny like the classic heroes. Modern man cannot defy or control the external situation of the modern civilization. So they are tragic. In this situation, the protagonist of the tragedy who challenges reality disappears and a puppet figure like Max Estrella, the protagonist of the Luces de Bohemia, takes his place on a satirical level. This is the satire and the true meaning of carnivalistic humor that Valle Inclán tried in his play.

The light is one of the most important factors in architectural design. Especially, natural light is the valuable source of illumination that can be utilized for better indoor environment. Compared to artificial light, it is a sustainable energy source without the cost of electric energy and offers a more natural feeling to residents stayed in buildings. Natural light also creates light and shadow in building. It enables people to perceive the depth of space. Many architects have tried to suggest various technologies to create optimum indoor environment by using the natural light. Therefore, this paper tried to examine the works of Le Corbusier and to analyze how to control the light in his works and apply it to his design. It will help to know how he created different characteristics to spaces by using natural light.

LED(Light Emitting Diode)는 전기 신호를 빛으로 신호를 보내고 받는데 사용되는 반도체의 일종으로 가정용 가전제품, 리모컨, 전광판, 각종 자동화 기기등에 사용된다. 3색광 백색 LED는 soft-UV 또는 blue 빛을 내는 device 와 RGB 형광체로 이루어져 있다. 현재 연구중인 3색광 백색 LED는 InGaN 또는 GaN 이 RGB 형광체를 여기 시키는것이 대부분이다. 이러한 경우에 유기물과 무기물 형과체가 백색광을 구현하기 위해 사용된다. 유기물의 경우에는 lift-time 이 짧고, 무기물의 경우에는 유해원소인 S, Cd등이 포함되기 때문에 환경오염이 야기된다. 이러한 단점을 보완하기 위해 진화 최적방법을 이용하여 alkali earth borosilicate ((Eu,Mg,Ca,Sr,Ba)$_{x}$ $B_{y}$ S $i_{z}$ $O_{d}$ ) 계열에 $^{Eu3+}$을 도핑하여 고효율 형광체를 합성하였다.

보완대제의학의 한분야인 Color Therapy에 대한 과학적 진단을 위해, 색(color)이 인체에 미치는 영향을 정량화 하기위한 선행 기초연구로서 자연광에 포함된 가시광선의 파장이 인체에 미치는 영향을 계측하고 분석하기 위한 시스템의 설계에 대하여 연구하였다. 인체를 구성하는 세포는 세포하나하나가 살아있는 생명체로서 주변환경에 대하여 반응을 하고, 그 반응으로부터 생체신호가 발생하며, 발생된 생계신호는 인체의 다양한 구성기관에 전달되고, 전달받은 기관은 그 신호에 반응한다[4][5]. 따라서 가시광선 영역의 색이 인체에 미치는 영 향분석은 보완대체의학 발전에 중요한 요소라 할 수 있다. 본 연구를 통해 설계한 "Color therapy 진단 System"은 가시광선 중에서 특정 파장대의 빛을 발생시켜 방사하며, 방사된 빛을 조사받은 사람의 신체가 반응하는 신체 상태를 한방적인 진단요소인 "맥", "기혈전류변화"[1][2], "체온변화"등을 계측하고 이를 정량화하는 연구를 수행하였다. 본 연구의 결과는 그 동안 시회저변에서 이루어지고 있던 보완대체의학 분야의 의료행위에 대한 과학화, 정량화를 위해 필요한 중요한 시발점으로 사료된다.

As quality of life improves, apartment's residents prefer residing type that have differentiation of resident center. Accordingly, community facilities such as fitness club, swimming pool, and so on are operated in apartment complex. Community areas are important space that can induce inhabitantses' natural meeting and contact, and that can solve social problems which is started each individuals' estrangement in current through community formation between neighborhood. From this point of view, this paper investigated the essence of light and the luminous environment for community areas. This paper finally suggested well-coordinated lighting plan of community areas, derived from the measurement and analysis of luminous environment in these cases.
