The aim of this study is to analyse the relationship between traffic noises and subjective responses. The traffic noises considered in this study were aircraft, road traffic and train, and we recorded them in order to edit by using the sound insulation performance of windows. The sound sources recorded and edited were made to be different sound level with 5 steps by 5dB. Finally 100 sounds sources were composed for the purpose of psychoacoustic experiments and we surveyed the subjective responses. As a result, the average points of the subjective response to the sound sources have shown differently depending on their sound level, the type of windows and the type of sound sources.

Background: The emergency treatment of multiple trauma patient includes rapid evaluation of mental status, triage and resuscitation. The principles of Advanced Trauma Life Support consist of primary survey & resuscitation, secondary surveys and definitive cares. In primary survey, the mental status is evaluated by AVUP scale, and GCS(Glasgow coma scale) is used in secondary survey because the calculation of GCS needs more times than AVPU scale. Purposes: Is there a correlation between AVPU scale and GCS as an evaluation method of mental status in trauma? Subjects: 434 injured patients(male 321, female 113, mean age 35.9 years) who had visited the emergency center of Wonju Christian Hospital was evaluated prospectively. The mental status was evaluated by AVPU scale and GCS by emergency physician as soon as the patients was admitted to emergency center. Results: Alert patients as AVPU scale were ranged from 14 to of GCS, patients who responded to verbal command were from 9 to 14 of GCS, patients who responded to pain stimuli were from 4 to 10 of GCS, and patients who did not respond to pain stimuli were from 3 to 5 of GCS. The linear correlation of AVPU scale and GCS was seen(r2=0.90). Conclusion: This study suggest that AVPU scale was vey closely correlated with GCS.

This study has performed to analyse the measurement the main hall of Catholic churches and to find out general room acoustical characteristics. Furthermore, extracted data could be used in subjective evaluation for optimum values of each physical parameter. For the reason, we surveyed whole Catholic churches located in Gwangju metropolitan city and finally chose 11 churches to measure. Room volume of buildings chosen is ranged widely from 1,782 to 9,195 cubic meter so that measured values can be distributed including various characteristics of acoustical parameters. As a result, the differences of values using PA system as sound source were larger than those using omnidirectional speaker in the center part of alter and values of D50 and C80 in the balcony floor were especially appeared to have different values comparing with those of main floor due to diversified layout of speakers. The range of RT and EDT was from 1 to 3 sec. approximately depending on the room volume and sound absorbing materials installed on floor, wall and ceiling and it was revealed that RT at 250㎐ of center frequency range was shortest and RT at 1㎑ was largest as most of the materials applied to finishing were panel absorbers and reflectors such as wood panel, concrete and brick.

This paper reports a suitable operating mode and condition through the economic and exergy analysis to a cogeneration power plant cycle with computer simulation. The exergy analysis that permits to predict the exergy losses in each component furnishes information to the quantity and the place of exergy loss. The simulation condition is to generate constant electricity in spite of the load change of process steam when the supply of process steam and pressure of condenser is changed, devided with sixteen kinds of operating modes according to the ratio of process steam by the auxiliary boiler to steam extracted from the high pressure turbine. Performing the computer simulation for the economic and exergy analysis with above condition, the results show that a cogeneration efficiency is increased as process steam supply is increased and the ratio of process steam by auxiliary boiler is decreased. Oherwise, a economics rate and a cogeneration efficiency are decreased as the pressure of the condenser is increased. And the boiler and the condenser have about 96 to 98 percent of the total exergy losses in a cogeneration power plant cycle.

DBME(Discipline-Based Music Education)에 의한 음악과 교육과정의 비판적 분석과 발전 방향 탐색

최윤경,강현석 이화여자대학교 사범대학 교육과학연구소 2005 교육과학연구 Vol.36 No.2

오늘날 음악 교육은 입시 위주의 교육 정책, 국가 경쟁력의 강화라는 표어 아래에서 학교 당국과 교사, 학생, 학부모에게 부담스러운 과목으로 외면당하고 있으며, 음악 교육의 가치와 당위성마저 흔들리는 위기에 직면해 있다. 이러한 위기는 현재까지의 음악 교육이 일반적으로 ‘음악 이론과 기능을 가르치고 음악 활동을 하는 교과’로 인식되어 왔고, 음악과 교육과정 역시 ‘이해해야 할 지식’과 ‘경험해야 할 행위와 활동’을 단순히 나열하고 있었기 때문이라고 할 수 있다. 우리나라와 비슷한 위기에 직면했던 미국은 예술 교육의 정상화를 위해 미술교육에서 DBAE(Discipline-Based Art Education) 이론을 개발하였고, DBAE의 연구 결과에 기초하여 음악 교육의 문제를 해결하고자 연구된 것이 DBME(Discipline-Based Music Education)이다. 이에 본 연구는 DBME의 역사적 배경, 목적과 내용, 특징을 살펴보고, 이를 통해 현행 음악과 교육과정을 비판적으로 분석하였으며, 향후 음악과 교육과정이 ‘사회적?역사적?문화적 맥락을 고려’하고, ‘사고와 탐구 활동을 강조’하고, ‘디지털 중심의 사회적 변화를 수용’하는 음악과 교육과정으로 발전하여야 함을 제안하였다. Today, music education is a burden to teachers, students and parents and music is recognized to difficult subject. The reason is why the purpose of education changes into the university entrance and the policy of economic growth has precedence. So, The value of music education have faced at risk. The reason is that music education was recognized by subject matter that teaches music theory and function and does music activity until now. And music curriculum lists knowledge to understand, and activity to experience. The United States of America that faced at risk similar our country developed DBAE(Discipline-Based Art Education) theory in art education to solve problem of art education. DBME(Discipline-Based Music Education) is based on DBAE and studied to solve problem of music education. DBME involves music-making, musical history, musical aesthetics and musical criticism. Each of these disciplines are related and integrated to provide students with a balance understanding of works of music. This study examines historical background, purpose, contents, characteristic of DBME for theoretical explanation. Through this, current music curriculum is analyzed critically. And the direction of music curriculum is presented as following. So Music curriculum that accommodates engineering, considers social, historical, cultural context, and emphasizes thinking ability is emphasized in the next music curriculum revision.

Purpose: The purpose of this study was to compare health lifestyles of elders according to area of residence. Method: A cross-sectional study was conducted with 2,545 elders living in urban (n=335), urban-rural composite (n=839) and rural (1,371) areas. Following informed consent, the elders completed a questionnaire. Chi-test, Fisher's exact test, and one-way ANOVA were used to analyze the data. Results: According to residential area, significant differences were found for age, educational status, occupation and household income (p<.01) and for plans to quit smoking (p=.005). Of elders currently smoking, 34.7% in urban-rural com -posite, 26.9% in urban and 16.7% in rural areas planned to quit within the next 6 months. Significant differences were found for alcohol consumption within the last month and frequency (p<.05). Exercise rates were highest in urban elders, but walking over 30 min was higher in urban-rural composite and rural elders (p<.05). Eating habits were least healthy in urban-rural composite (men 10.4%, women 11.3%) and rural elders (men 9.0%, women 15.6%) compared to urban elders (men 1.6%, women 0.0%) (p=.000). Conclusion: Health lifestyle for elders is significantly different according to residential area, indicating a need to develop community -based health care programs to improve elders' health lifestyle.
