Recent research on stand-alone focused on the improvement and development of functions for solving problems such as the limited operating time of stand-alone installed at dwelling and their low reliability caused by false alarms, but it is more urgent to study on the operating range of stand-alone sensor in consideration of the impacts of combustion products on residents because the primary goal of fire safety is minimizing casualties. This study purposed to propose the optimized operating range of stand-alone sensor in consideration of the impacts of combustion products on residents. For this purpose, we made a mathematical approach to the change of temperature over the lapse of time in compartment fires similar to house fires, and established the standards of the body's response against heat and smoke based on literature review. In addition, we surveyed domestic and foreign technological standards for stand-alone sensor, and converted them to standards for residents of the body's response against heat and smoke using mathematical model equations and analyzed them comparatively.

청소년들의 학습, 일, 수면, 기타 필수적인 것에 소요된 시간을 제외한 교제 및 여가활동을 위한 기준시간은 통계청의 자료에 의하면 1일 평균 4시간 45분으로 나타나고 있다. 급격한 정보화가 진행되면서 청소년들의 여가활동은 TV시청 이나 컴퓨터게임 등에 편중되고 있어 정부에서는 이에 대한 부작용을 최소화하기 위해 게임셧 다운 제도까지 도입하였다. 그래서 본 연구에서는 청소년들의 취미ㆍ특기를 일반청소년과 범죄청소년간의 차이, 취미ㆍ특기별 성격유형이 범 죄에 미치는 영향, 범죄청소년과 취미ㆍ특기별 성격유형을 비교분석하였다. 범 죄청소년은 노래부르기, 구기운동, 정적형, 당구 등 순으로 선호하고, 일반청소년은 구기운동, 노래부르기, 예술형, TV시청 등 순으로 취미ㆍ특기활동을 하는 것으로 나타났다. 그러나 전자게임ㆍ격투기ㆍ영화감상ㆍ음악감상ㆍ스포츠 등은 일반ㆍ범죄청소년 사이에 유의미한 차이가 없었다. 취미ㆍ특기종류별 성격유형 이 청소년범죄여부에 대해 스포츠형(67.9%), 독서(54.6%), 그림그리기(46.2%), 격투기(41.8%), 정적형(39.7%), 예술형(39.5%), TV시청(36.8%), 영화감상 (35.7%) 음악감상(22.6%), 구기운동(17.3%), 전자게임(13.3%), 노래부르기 (9.8%) 등 순으로 유의미한 영향을 미치는 것으로 나타났다. 범죄청소년과 취미 ㆍ특기종류별 성격유형에서는 노래부르기ㆍ격투기ㆍ당구ㆍ영화감상ㆍ정적형 등은 준법성이 낮게 나타나는 등 유사한 형태를 보이고 있다. 반면에 구기운동 ㆍ예술형ㆍ독서ㆍ스포츠형ㆍ요리 등은 준법성이 높게 나타나며 범죄청소년과 차이를 보이고 있다. 한편 전자게임과 TV시청은 범죄청소년 보다 준법성은 높으나 자아정체성, 창의성, 사교성이나 친화력, 인자함과 탐구성 등에서 범죄청소년들보다 매우 낮게 나타나고 있어 청소년의 인성발달에 부정적 영향을 준다고 볼 수 있다.

이 연구는 제7차 교육과정의 취지에 맞는 수준별 수업을 내실 있게 운영하기 위해서 시작하였다. 사교 육의 팽창으로 많은 학생들이 단순 문제 풀이식이나 반복 학습의 영향으로 이론에만 익숙할 뿐, 각 단원 의 학습 목표나 본질을 이해하지 못하는 경우가 적지 않다. 문학 작품마저도 스스로 찾아 읽고, 말이나 글로 즐거움을 공유하고 쌓아나가는 경험을 하지 못하는 실정이다. 수준별 수업의 효과를 높이기 위해서는 수업 방법은 물론, 새로운 평가 방법 마련이 절실하다. 수준별 수업을 실시하더라도, 그것을 일률적인 잣대로 평가하는 것은 무의미하다고 할 수 있다. 이에 연구자는 문학 단원을 중심으로 단원의 특성과 학습자의 수준에 적합한 수행평가 프로그램을 구안하고, 각 장르별 활동을 ‘따라하기’, ‘변화주기’, ‘확장하기’의 3단계로 구분하여 학습자가 자신의 흥미나 능력에 맞는 프로그램을 선택하여 활동하도록 하였다. 문학 장르와 활동 내용에 따라 수시로 수준을 이동· 선택할 수 있도록 함으로써 활동에 대한 흥미를 고조시켰다. 또한 학습 목표에 적합한 수준별 수행평가 기준안을 마련하고, 다양한 수준별 수행평가 자료를 구안·적용함으로써 학생들의 문학 작품 감상 능력 신장 방안을 모색하게 되었다.

Optical characteristics and structural changes depending on CuO content in phosphate glasses that are used in near-infrared (near-IR) filters were investigated. With phosphate glasses that contain 1-9 mol% CuO, changes in optical transmittance, optical absorption, and color coordinate were measured with a UV-VIS spectrophotometer. An XPS (X-ray photoelectron spectroscopy) analysis was performed to determine valence of copper ion that influences optical characteristics in near-IR filter glasses. Structural changes in glasses depending on CuO content were also analyzed by FT-IR (Fourier transform infrared) and Raman spectrophotometers. From the UV-VIS spectrophotometer results, strong absorption peaks at 220 & 900 nm were found and transmittance was decreased. The color coordinates of the glasses were shifted to the green color direction with CuO addition for increasing absorption of long wavelength range spectra, in spite of the amount of Cu2+, which gives a blue color to glasses, and which was increased in XPS results. Also, structural de-polymerization of glasses with CuO addition were found by FT-IR and Raman results.

In the fire there are fusion signs and damage by fire, and insulation aging and carbonization of the electric wiring in the ignition spot because of special characteristic of the appliance in the electricity fire.
