Most of the stone cultural properties is exposed to the weathering factor(rain, windetc.), so the shelter is constructed for reduction of its direct effect. But the shelter is indicated some problems that inharmoniousness of the surroundings, in section disturbance for insufficiency of light, the loss about the value of cultural properties and so on. So we have investigated on environmental condition (temperature, relative humidity, wind etc.) at the Standing Stone Buddhist Triad in Bae-ri, Gyeongju and Rock-carved Triad Buddha in Seosan because check the effect of the shelter. As the result, the Standing Stone Buddhist Triad in Bae-ri, Gyeongju is located a pine wood and a lot of bamboo grow naturally in nearing. Environmental difference on inside and outside of the shelter is not found because opened on all sides. But there is so dim for the direction of the sunlight that can't see the Standing Stone Buddhist. The base rock of Rock-carved Triad Buddha in Seosan well develop with crack and break, and the vegetation(trees, moss, lichen etc.) grow naturally in surroundings. Environmental difference on inside and outside of the shelter is found because closed on all sides and opened the front gate only inspection time. Inside of the shelter was too calm(air-velocity not detected) and humid(over 75%RH). Also the surface is occurred the dew(at 2-4 pm) and the efflorescence for effect of the water(rain, dew etc.). Besides the head of the central Buddhist is so dangerous for crack.

The facilities of exhibition and collection for cultural properties is affected by environmental pollution. In order to accumulate a store of basic data, we was investigated eight points(three points at exhibition room and five points at collection room) at four institutes, from December 2000 to March 2001.As a result of investigation, the temperature of A-Exhibition room measured low because of don’t moved HVAC(Heating, Ventilation and Air-Conditioning) System, B Exhibition room is dry for the effect of air-conditioner and the air pollutants concentration of C-Exhibition room is high for the kind of an exhibition room. The air-condition was varied within the open period. The air pollutants concentration of A-Collection room is measured high because the air-pollutants is generated in a new buildings and the air pollutants concentration of C-1 & C-2-Collection room is high for the kind of an collection room. It is necessary to ventilate sufficiently.

Yearly mean temperature and relative-humidity of the Seokguram Grotto was measured $19~23^{\circ}C$, 40~44% from May, 1998 to December,2002. The measurement has little differences comparing to the optimum guideline (temperature : $20^{\circ}\pm2^{\circ}C$, relative-humidity : $50^{\circ}\pm5%$). It is necessary to increase humidity in the Seokguram Grotto during winter because of heating and decrease the temperature during summer because of a higher temperature of outside. In addition, the diurnal range keep in $4^{\circ}C$ of temperature and in 10% of relative-humidity. Yearly mean concentration of $CO_2$(carbon dioxide) was measured538~658ppm that is higher than concentration of normal atmosphere(360 ppm). The $CO_2$ has an cumulative effect on the surface of stone cultural properties as a form of carbonic acid($H_2CO_3$) after reaction with water. HVAC (Heating, Ventilation and Air Conditioning) system should be operated to maintain ideal state for the preservation according to the optimum guideline. Also, the entrance into the Seokguram Grotto should be controlled to prevent a sudden fluctuation of humidity and temperature. Human could carry small particles like a microdust, microbe, etc., into the Seokguram Grotto and also could damage the surface by a direct touch.

Seoul City built a facility for conservation of the Wongaksajisipcheungseoktap (Ten storied stone pagoda of Wongaksa Temple site, National treasure No. 2). It has speciality glass(thickness 21.5㎜) between steel-frames(8.4m, length 8.4m, height 15.4m). So we investigated the inside of facility to know whether the environment alvariation exists. We measured continuously the temperature and relative humidity, twice for the particulate, once for the $SO_2$(sulfur dioxide), $NO_2$(nitrogen dioxide)and $O_3$(ozone) from September $1_st$, 2000 to August $31_st$, 2001.The temperature and relative humidity, have a tendency to vary, and they have no difference between the inside and the outside. As dewy phenomenon doesn appear on the surface of the Pagoda and facility we know that the inside air is moving. As a result of the particulate is $64\mug$/$m_3$ of average concentration, the particulate fluxed inside don’t flow out because air-velocity of the outside is faster than that of the inside. The air pollutants are 0.036ppm/hr of SO$_2$average concentration, 0.028ppm/hr of $NO_2$ average concentration and 0.008ppm/hr of $O_3$ average concentration which are lower than the Environmental Air Quality Standards($SO_2$ : 0.15ppm/hr, $NO_2$ : 0.25ppm/hr,O3 : 0.1ppm/hr).

스마트폰은 보편화되었고 가전기기나 각종 생활 기기에 통신 장치 및 센서가 내장되어 스마트폰과 연동되는 다양한 스마트 기기들이 개발되고 있다. 또한 사용자가 인지하지 못한 상태에서 사용자에게 자동으로 편의 기능을 제공하는 서비스 기술들이 매우 활발하게 개발되고 있다. 하지만 현재의 스마트폰을 이용한 음성 통화는 단순한 사용자 인터페이스 수준에 머물고 있다. 따라서 본 논문에서는 정황 인지형 커뮤니케이션 기술을 활용하여 개인 맞춤형 및 다수 통화자간의 인터랙티브 커뮤니케이션 서비스에 대한 구조 및 요소기술에 대하여 제안한다.

정보화 사회, 디지털 사회로 넘어오면서 정보의 중요성이 강조되고 동시에 정보를 습득하기 위한 기술이 발달하였다. 일반인들은 스마트폰, 태블릿 등의 전자 기기를 사용하여 정보를 쉽게 획득하는 반면 시각장애인은 여전히 정보의 사각지대에 머물러 있다. 이러한 정보의 비대칭 현상을 해결하기 위하여 휴대가 가능한 착용형 전자 점자 기기를 개발하기 위한 연구가 진행되고 있다. 본 연구는 이러한 흐름 속에서 착용형 전자 점자 기기가 차용할 수 있는 인터페이스 형태에 대해 제시하고 있다. 특히 한글 점자의 특성에 맞추어 점자를 초성, 중성, 종성으로 구별하여 제시하는 인터페이스와 이를 검증할 수 있는 실험 설계를 제안한다. Since we are living in information-oriented society, also so-called as digital society, the importance of obtaining information is greater than any times, and thus the technology for acquisition of information has been improved rapidly. However, blind people are still limited to take those advantages. To solve this issues, many researchers are focusing on developing wearable electronic braille device. In this paper, we propose an interface device for Korean braille. The interface we propose has advantage of using multi braille cells with representing first, middle, bottom components of Korean braille to increase read efficiency for blind people. Our experimental subject test validates the efficacy of the proposed interface.
