Oxygen deficiency has been frequent in a clouted space. Wood consumes oxygen and discharges carbon dioxide Instead of photosynthesis in closed space without light, so do some microorganisms on the surface. We experienced a case that a healthy Insect-proofer fell down and died of asphyxia on stair-board at 7 m below the hatch of the cargo-hold shipping wood Analysis of gases in cargo-hold revealed O2; 12.3%, CO; 105 ppm, CH4; 2.7%, and H2S; 1.9% at 1 m below the hatch, and then O2; 6.1%, CO; 220 ppm, CH4; 2.9%, and H2S, 2.3 ppm at 2.5 m below the hatch. Autopsy findings were unremarkable. We justiced the cause of death asphyxia due to oxygen deficiency. As seen in this case, the serious oxygen deficiency was accounted for oxygen consumption by wood and microorganisms.

Selective posterior rhizotomy(SPR) has been known to reduce the spasticity as well as to improve the quality of life in patients with intractable spasticity. Twenty patients underwent SPR under intraoperative electrophysiological monitoring(IOM). Fifty-two percent of sacrolumbar rootlet were cut after electrical stimulation. Eighteen patients(90%) with spastic type of cerebral palsy showed marked reduction of spasticity and functional improvement without any complication. The patients who did not respond to SRP had mixed types of spasticity. IOM facilitate the selection of pathological rootlets regardless of anaesthetic level. intensity of electrical stimulation, and individual variability of responses. It is concluded that careful selection of surgical candidates and of pathological rootlets under IOM are important to reduce the spasticity. thereby to obtain a better outcome.

This paper introduces a development of an electrical stimulator for auditory stimulation. The electrical stimulator is useful in neurotological diagnosis, audiological evaluation, candidate selection for cochlear implantation, optimal device selection and decision making of MAP strategy for severe-to-profound hearing impaired persons. The development was based on sound parameters of auditory brainstem responses and auditory electrophysiological characteristic such as effective firing of auditory nerve and recording evoked potentials during refractory period of neuron. Besides pulse parameter could adjustable by programming for more varied electrical stimulation evoked response audiometry. Using the electrical stimulator, electrical square pulse was applied to promontory, and electrically evoked auditory brainstem response and electrically middle latency response were successfully recorded in cats.

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.

Ankylosing Spondylitis is a chronic progressive inflammatory disorder of unknown etiology involving principally the axial joints of the spine, chiefly the sacro-iliac apophyseal and costovertebral articulations resulting in not only deformity but also functional disability in terms of cardiopulmonary dysfunction and activities of daily living. The purpose of this study is to find out the effects of the therapeutic massage applied to the patients with Ankylosing Spondylitis by measuring, assessing and analyzing the changes muscle pains before and after Patient Education and Therapeutic Massage. In the therapeutic massage program, such methods as effleurage, petrissage and deep transverse friction were selected as traditional massage treatments frequently used for muscles with pain and spasticity. Effleurage and petrissage were applied for 20 minutes in total before and after deep transverse friction treatment. We assessed the effects of patient education and therapeutic massage in ankylosing spondylitis. The subjects of this study were 23 patients with confirmed ankylosing spondylitis by New York criteria who had visited J Sports Massage Clinic from January, 2001 to August, 2002. We have made two sessions of patient education and therapeutic massage for 4 weeks. The major findings from this study are as follows; 1. There were significant improvements in pain, nocturnal awakenings, morning stiffness, functional status, forward flexion of trunk, and lateral flexion of trunk. 2. The treatment outcomes were poor as the disease duration increase. 3. There was significant decrease in the numerical values of VAS, VRS and MPQWL after Therapeutic massage(p<.05). 4. There was significant decrease in the intensity and unpleasantness of pains after Therapeutic massage(p<.05). 5. From the analysis into chronological changes in the intensity and unpleasantness of pains before and after Therapeutic massage with ANOVA, it became evident that the longer the period of treatment was, the higher the pains decreases drastically, while significant difference was shown in the intensity and unpleasantness of pains(p<.05). Summed up, it can be generally concluded that Patient Education and Therapeutic Massage is an effective treatment to rid the patients with Ankylosing Spondylitis of pains safely and promptly.

선호강도와 비선거적 정치참여

This thesis is to study the relation between the intensity of preference and non-electional political participation. If the cost of political participation is varied in sort of political participation, the constituent should select the path of political participation of which the cost is low. Nevertheless the constituent often selects the path of political participation of which the cost is very high. Therefore this thesis defining the political participation as action of the constituent who is not in charge of decision-making but is intend to effect on the decision-making divides the non-electional political participation into the conventional participation and the non-conventional participation. And on the relation between the intensity of preference and the non-electional political participation this thesis views that the intensity of preference can be measured cardinally. The character of conventional participation is that participation means the routine ways by the institutional path, acted before policy making, acted by the active of high stratum who have much political resources, has high possibility which can be included in the policy making, and should be explained multidimensionally. The character of non-conventional participation is that participation means the form of non-institutional path, shows the nature of resistant to the outcome of policy making, acted organizationally enthusiastically by the constituent who has little political resources, shows the nature of issue-turnover, has weak legitimacy, and demands high cost of the participation. And the relation between the intensity of preference and conventional participation is that the cost is low, the intensity of preference is also low. Therefore conventional participant maximizes the effects of preference by utilizing the political resources strategically and multidimensionally. But the relation between the intensity of preference and non-conventional participation is that the cost is high, and the intensity of preference is also high. Therefore the higher the intensity of preference is, the higher the possibility for participant to select non-conventional participation is in the relation between the intensity of preference and non-electional political participation. And the lower the intensity of preference is, the higher the possibility for participant to select conventional participation is.

The synthesis of fuels from waste organic solvents was investigated through continuous distillation and catalytic cracking. Waste organic solvents could be controlled with the composition of diesel and kerosene fuels selectively with varying reboiler temperature in the multiple continuous distillation tower. In particularly, hydrocarbon compounds of C_15 and over could be converted to hydrocarbon compounds of C_7∼C_14 range over stylene-divinylbenzene solid acid resin catalyst. Linear hydrocarbon compounds were converted to branch hydrocarbon compounds by isomerization, and this effects were promoted capacity of fuels.

Maleic acid의 촉매습식산화의 반응경로에 대한 연구

김둘선,이동근 경상대학교 환경보전연구소 2000 環境保全硏究所報 Vol.8 No.-

Catalytic wet air oxidation of maleic acid solution was carried out in a batch reactor Pt/Al₂O₃, Pd/Al₂O₃, Rh/Al₂O₃ were used as catalysts. Maleic acid was proved to be a refractory substance which could not be oxidized at all at atmoshperic pressure, and needed high pressure and high temperature operation for its oxidation. Fumaric acid, oxalic acid and formic acid were produced as reaction intermediates. On the basis of these intermediates the pathways of maleic acid oxidation were proposed. Maleic acid and fumaric acid are converted ito oxalic acid which subsequently degrades into formic acid. Finally formic acid is totally oxidized into carbon dioxide and water.

The purpose of this study was to know stress distribution of ceramic crown according to the cusp angle. For the study, it was manufactured a three dimensional finite element model simplified maxillary first premolar, and then analyzed stress distribution when cusp angle was each 80°, 90°, l00°, 110° and 120°. The results obtained were as follows; 1. The von Mises stress showed that stress decreases as cusp angle increases in the central groove of the occlusal surface. 2. It showed that maximum principal stress was centered at the region of the central groove of the occlusal surface and a region which the force was inflicted. And also it appeared high on the lingual and buccal side of finish line. 3. The X axis of normal stress was focused in the central groove of the occlusal surface. The Y axis of normal stress appeared high in the central groove of the occlusal surface, b u d and lingual side. 4. The stress near the finish line showed a low value compared with stress in the region of the central groove of the occlusal surface. 5. It showed that the most dangerous angle for tooth fracture was on 80° of the cusp angle and low on 120° of its.
