Fire extinguishing systems using gaseous agents are widely used either where the chance of rapidly developing fire occurring is high, or where the consequences of such a fire would be particularly serious for life and property. Important considerations when specifying such an extinguishing system include the speed and assurance of extinguishing and the containment and minirnisation of fire damage and consequential loss. Fire extinguishing systems using gaseous agents have been the most commonly chosen total flooding systems, notably for the protection of electronic data processing equipment such as computer suites and telephone switchrooms and for flammable liquid risks. But there are not a fire designs, system pipework pressures, pressure generated in the enclosure for the gaseous agent systems. This paper describes the problems and solutions of the fire extinguishing systems using gaseous agents in korea.

이희봉,홍세희 중앙대학교 건설환경연구소 2001 環境科學硏究 Vol.12 No.2

현대의 상업공간에 물을 도입하여 인간의 활동에 활력을 주려는 시도가 점증하는바, 최근 개설된 쇼핑몰을 대상지로 하여 문화기술학적 (文化記述學) 현장연구를 수행하였다. 그 결과 현대 수공간은 시각적인 형태나 장식에 치중함으로써 이용자의 공간사용에 여러 가지 문제를 드러내고 있다. 이를 다시 전통의 수공간과 비교하면서, 문제점을 중심으로 전통의 도입요소를 고려하여 현재의 상황에 적합하도록 대안을 모색한다. Water spaces are installed at commercial shopping mall for amusement of people. Several shopping malls opened last year are examined whether they really designed for people's everyday life or not. The study shows that the designed water spaces at present unsuitable due to the insufficient understanding users and the space itself, so the place have a role of a visual space of decoration. This study aims to review the problems of a modern water space and suggest alternatives by introducing the traditional design concepts of water space to the present situation.

The objective of this study was to develop recommendations for designing a park in commemoration of Chonbuk National University's 50th anniversary. The study progressed in accordance with the design process and questionnaires were used to collect data on developing a program. The park is divided into three parts, with spaces for the past, present, and future. Water that flows through the spaces represents the stream of time. The facilities for two basic elements of life, work and relaxation, are located in both sides of the visual axis with asymmetric balance. From analyzing the existing topography and landscape character, proposed landforms and grade changes will be of varying construction. In some areas, the visual landscape will be emphasized. It will be negated elsewhere. The plantings will be used to achieve visual control and produce a diverse landscape which changes with the seasons. The monument, symbolic sculpture, and shelters are designed to represent the 50th anniversary of the university.

차봉석,왕승준,장세진 大韓産業醫學會 2000 대한직업환경의학회지 Vol.12 No.1

목적 : 이 연구는 적출간 관류법을 이용하여 영화니켈과 염화카드뮴의 동시 노출로 인하여 간에 나타나는 효과를 확인하는 데에 있다. 방법 : 간독성의 지표로서 AST, ALT, LDH의 농도 및 관류속도를 이용하였고 생존력에 대한 지표로서 산소소모율을 측정하였다. 300(±50) g의 흰쥐를 노출군(비노출군 및 50 μM/ 200 μM의 각 농도별 염화니켈과 염화카드뮴의 개별 투여군 및 동시 투여군)별로 5마리씩 총 35마리를 할당하였다. 간을 통과한 관류액을 채취하여 생화학적 간독성 지표를 측정했고 집단간의 시간의 경과에 따른 측정치의 비교를 위해 반복 측정된 2요인 분산분석을 실시하였다. 개별 투여군과 동시 투여군의 생화학적 지표간의 평균을 비교함으로써 상승효과에 대한 가능성을 확인했다. 결과 : 개별 투여군 및 동시 투여군 모두에서 AST, ALT, LDH가 증가했다. 관류속도 및 산소 소모율은 시간의 경과에 따라 감소했으나 통계적으로 유의한 차이를 보이지는 못했다. AST, ALT, LDH, 산소소모율이 일정 시간대 이후로 개별 노출군의 합보다 동시 노출군에서의 측정치가 더욱 크게 증가하였다. 결론 : 간독성에 대한 생화학적 지표의 변화를 확인함으로써 두 물질의 동시노출로 인한 복합적 효과는 상승효과일 가능성이 높은 것으로 보인다. Objectives : This research was intended to verify hepatic effect of simutaneously com-bined exposure of nickel chloride and cadmium chloride with IPRL (Isolated Perfumed Rat Liver) method. Methods : AST(aspartate aminotransferase), ALT(alanine aminotransferase), LDH (lac-tate dehydrogenase) and perfusion flow rate were used as the indicator of hepatotoxicity and oxygen consumption rate were used as the indicator of viability. 300(±50) g - weighted rats were allocated randomly to each group (control group, 50 μM·200 μM sera-rately exposure group of NiCl₂and CdCl₂, simultaneously combined exposure group of NiCl₂and CdCl₂by 5, totally 35. Buffer which got out of liver was sampled and then biochemical indicator of hepatotoxlcity was measured. In order to verify difference among groups, two way - repeated ANOVA was used. With comparing mean summation of sepa-rate exposure group with mean of simultaneous exposure group, possibility that combined effect could be synergistic effect was verified. Results : AST, ALT, LDH increased in both of separate exposure group and simultaneous exposure group. Perfusion flow rate and oxygen consumption rate decreased but statlstically significant difference among groups was not found. In each exposure group, AST, ALT, 7DH, oxygen consumption rate of simultaneous exposure group increased more than sum of separate exposure group after any sampling time. Conclusions : It was found that simultaneous combined effect could be synergistic effect through the biochemical indicator of hepatotoxicity.

Objectives: This study examined the relationship of fatigue to medical utilization, occupational accident and sickness absence. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project, 2002~2004). A total of 30,146 employees categorized within the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were recruited. A structured-questionnaire was used to assess the participants' sociodemo-graphics, job-related factors, health-related behaviors, personality trait, self=perceived fatigue (MFS) and the frequency of medical utilization, occupational accident and sickness absence. Data on medical utilization and occupational accident were confirmed from company health records. Chi-square test and logistic regression analysis were used to elucidate the relationship of self-perceived fatigue to medical utilization, occupational accident and sickness absence. Results: In logistic regression analyses, self-perceived fatigue was associated with medical utilization (outpatient), occupational accident and sickness absence although the strength of the associations was higher in the blue collar workers except for medical utilization. For medical utilization, the white collar worker's adjusted odds ratios of outpatient utilization for workers scoring in the third quartile and the highest quartile, compared to workers scoring in the lowest quartile were 1.50 (95% CI: 1.20-1.87) and 2.16 (95% CI: 1.69-2.75), respectively. The blue collar workers' adjusted odds ratios of outpatient utilization for workers scoring in the second (OR: 1.23, 95% CI: 1.06-1.43), third (OR: 1.42, 95% CI: 1.22-1.66) and highest quartile (OR:1.83, 95% CI: 1.55-2.17), respectively, compared to workers scoring in the lowest quartile were statistically significant. However, no associations were found between fatigue and inpatient utilization for either the white or blue collar workers. The blue collar workers' adjusted odds ratios of being injured for workers scoring in the second, third and highest quartile were 1.41 (95% CI: 1.00-2.00), 1.57 (95% CI: 1.10-2.22) and 2.41 (95% CI: 1.69-3.44), respectively, compared to those scoring in the lowest quartile, but, those of the white collar workers were not significant. There was more likely to an increased risk of sickness absence in workers scoring in the second, third and highest quartile compared to those scoring in the lowest quartile in both white and blue collar workers, but the magnitudes of risk were higher in the blue collar workers than the white collars workers. Conclusion: This result suggests that fatigue is a determinant predictor of medical utilization, occupational accident and sickness absence, and that the pattern of risks for the three outcomes differs according to the occupational type. Some limitations of this study and considerations for future study were also discussed.

The purpose of this study is to analyze the conservation management and using development of the Moak-san provincial park with special regards to natural and cultural environment. Recently, with the rapid increase of use about national and provincial parks as a area of outdoor recreation, our natural park faces a serious environmental problems. So the quality of outdoor recreation has been decreased. Therefore, The conservation methods of natural park and resourse are very important for the maintenance of natural and cultural environment. Kumoh-san was appointed at first as a provincial park in 1970. And 20 provincial parks are present now in Korea. Moak-san provincial park extends over 2 Shis and 1 Gun including Kimjea-Shi(28.22㎢), Wanju-Gun(10.69㎢) and Chonju-Shi(3.31㎢). It's location is at 127˚ 02' E and 35˚42' N. In its climate, the annual mean precipitation is 1134.3mm, and temperature is 12.0∼12.5℃. In this park area, mostly Buddhist cultral asserts are collectively preserved, such as the Kumsansa, Kuksinsa. Soowangsa and Daewonsa. Vegetation of Moak-san was investigated 440 species. The Fegaceae is main species. As remarkable thing of park use, the trail which make an effect on the park resource conservation and effect promotion of park use established but if asked thorohgh management, because of intense gully erosion phenomenon. Recently, in the direction of Kumsansa and Kui project is developing or planning, but in the direction of Chunginri project is not established yet, so we request the valance Moak-san total development pslan. In the development plan, rational harmony of development and conservation was pointed out the essense factor.

This study was carried out to evaluate the effect of playing musical instruments on hearing threshold level from May to October, in 1997. Pure tone audiometric tests was provided to musical instruments playing group of total 117 subjects(Samullnori; 35, military band; 25, symphony orchestra; 46, piano; 11), and reference group of total 7,477 subjects, selected after excluding workers with history of ear disease, of ototoxic drug administration, of noise induced hearing loss at workplace in Pohang industrial area. In addition, noise exposure levels of musical instrument players were assessed by noise dosimetry(exchange rate; 5dB, threshold level; 80dB, criterion level; 90dB), and produced age-adjusted hearing threshold level(=hearing threshold level of musical instrument player - hearing threshold level in same age of normal population group). The age-adjusted hearing threshold levels were analyzed by musician's career. The results were as follows; 1. The hearing threshold level of reference group was revealed more increased as within 4.98dB to 6.89dB at 1 KHz and within 5.26dB to 14.46dB at 4 KHz by ages than "the Standard of Age-adjusted Hearing Loss by Frequency(OSHA)" used for special health examination in the Ministry of Labour. 2. Equivalent continuous sound exposure level (Leq) by the group of instrumentalist was as following; within 104.95 to 112.62dB in samullnori, the highest, within 100.18 to 103.49dB in military band, within 77.00 to 82.74dB in symphony orchestra and 81.54dB in piano, the lowest. Playing maximum sound level by each musical instrument was as following; 122.8dB in Kkwaenggwari, the highest, 122.7dB in Changgo, 121.8dB in Alto saxophone, 115.5dB in Trumpet, 119.2dB in Horn, 112.8dB in Pungmul Buk and Ching, 112.5dB in Clarinet. 3. Average age-adjusted hearing threshold levels of instrumentalists were -0.65±6.38dB in left ear, -0.92±6.59dB in right ear at 1 KHz, and -1.14±12.88dB in left ear, -1.53±12.77dB at 4 KHz, which were better than normal, but the average age-adjusted hearing threshold levels of Samullnori players were 1.23±5.22dB in left ear, 1.94±6.91dB in right ear at 1KHz, and 8.40±15.75dB in left ear. 7.13±14.97dB in right ear at 4KHz, which were worse than normal. 4. Hearing threshold level in Samullnori players was increased with their career at 4 KHz, especially it increased rapidly when the musicians had played over 10years. It showed that there was a significant relationship between hearing threshold level and the career (P<0.01).
