미소중력장에서의 연소특성 연구

이근오,이경욱 한국산업안전학회 2002 한국안전학회지 Vol.17 No.4

The transient soot distributions within the region bounded by the droplet surface and the flame were measured using a full-field light extinction technique and subsequent tomographic inversion using Abel transforms. The soot volume fraction results for n-heptane droplets represent the first quantitative assessment of the degree of sooting for isolated droplets burning under microgravity condition. The absence of buoyancy(which produces longer residence times) and the effects of thermophoresis produce a situation in which a significant concentration of soot is produced and accumulated into a soot-cloud. Results indicate that indeed the soot concentration within the microgravity droplet flames(with maximum soot volume fractions as high as ~60ppm) are significantly higher than corresponding values that are reports for normal-gravity flames. This increase is likely due to longer residence times and thermophoretic effects that manifested under microgravity conditions.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

Complex regional pain syndrome type I, formerly known as reflex sympathetic dystrophy and complex regional pain syndrome type II, formetly formerly known as causalgia, are debilitating pain syndroms that have recognized for more than a century. Complex regional pain syndroms remains a poorly understood chronic pain condition with regards to patho-physiology and treatment. According to the International Association for the study of Pain criteria, the characteristic frature required to establish the diagnosis of complex regional pain syndrome type I are as follows: (1) the presence of an initiating noxious event or a cause of immobilization; (2) continuing pain, allodynia; (3) evidence at some time of edema, change in blood flow; and (4) the exclusion of medical conditions thath would account for the degree of pain and dysfuntion. Therapies for complex regional pain syndrome type I are guided by the recogntion of the complex interaction between approach. In general, there is an incremental incorporation of therapeutic measures that combine aspects of physio-therapeutic, pharmace-therapeutic measures chotherapeutic modalites. But the patho-physiologic mechanisms of complex aging the signs and stmptoms of the disease. Nevertheless, no specific personality development of complex regional pain syndrome. Therefore we have to study the new research criteria to refine many smples in clinical reseach to establish efficacy of treatment.

This study was carried out to evaluate the relations among working environments, health behaviors and satisfaction with their duty in a group of 200 ship-repair workers in the ROK navy. The results were as following; Age of workers was 40 years and over(83%) and working duration was 10 years and over (71.5%). Most of them were married and had studied beyond high school. The 69.5% of workers satisfied with their job, whereas. about 59.5% of workers had satisfaction with their working condition. There were current drinkers, 78.5%, current exercising workers, 43.5%, obese workers, 28.0%, and salted food intakers, 18.5% in the workers. The major harmful environmental factors in the ship-repair workplace are noise, vibration, dust and chemicals. Most of workers are exposed to above harmful factors and complained about exposure of noise and dust. The consumption of cigarette or alcohol in people who exposed to noise was much higher than in people who did not, but the difference was not statistically significant. Prevalence of obesity and hypertension were not significantly different between the exposure with noise and dust. Noise or dust exposure was significant relation to satisfaction with their duty and working condition. The affective factors for satisfaction with their duty were people who worked for 10 years or more(OR= 4.53), exercisers(OR=4.78) and dust(OR=3.05) in Logistic regression analysis.

室內火災의 安全待避時間

이근오,태순호,김일종 서울産業大學校 1993 논문집 Vol.38 No.1

In the event of fire in a compartment the time available for occupants to evacuate the compartment safely, the Available Safe Egress Time (ASET), depends on the time of fire detection and on the time of the onset of hazardous conditions. The purpose of this study is to provide an analytical basis and experimental data for estimating the fire growth in compartments and the available safe egress time. The paper used the purposed equations that about mass loss rates, smoke layer height, temperature rise of hot gases in a compartment, ventilation flow rate, and flame height. As a result, the more fire load were increased, the more mass loss rate, smoke layer height, smoke layer temperature rise, ventilation flow rate, and flame height were enlarged, however available safe egress time were suddenly shorted.
