Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

This study was conducted in order to explore general flora of the Gyounggi-do Province and to clarify the distribution of some specificated taxa of the Korea. Daebu-do Island, Mt. Taewha, Mt. Hwaya, Mt. Gumdan, Mt. Chilhyun and Mt. Chulma among eighth grade-area of the Degree of Green Naturality (DGN) within the boundary of the Gyounggi-do Province were visited to investigate local flora. The number of identified vascular plant species were as follow; Mt. Hwaya: 120 species (99 genera of 67 families), Mt. Teawha: 132 species (103 genera of 56 families), Daebu-do Island: 124 species (103 genera of 50 families), Mt. Chulma: 129 species (99 genera of 67 families), Mt. Gumdan: 121 species (96 genera of 52 families), Mt. Chilyun: 90 species (74 genera of 42 families). The endemic Clematis brachyura Maxim. was found to distribute Daeby-do. It seemed that plantation was occupying large area in forest of the Gyounggi-do Province. Forty two specificated taxa were identified and 3 taxa, 10 taxa, 5 taxa, and 24 taxa were sorted into forth grade, third grade, second grade, and first grade respectively. Mt. Taewha showed the highest record (16 taxa) in the number of specificated taxa, Mt. Hwaya was the next with 13 taxa. Mt, Chulma (12 taxa), Mt. Gumdan (11 taxa), Daebu-do Island (7 taxi), and Mt, Chylma (4 taxi) followed. Mt. Taewa and Mt. Whaya were found to be relatively higher in the score calculated front the specificated taxa distribution, while Daebu-do Island and Mt. Chilyun were lower, that difference was probably due in part to consequences of severe disturbance of human activities. With respect to the consequences of severe disturbance of human activities. With respect to the geographical proximity to the Gangwon Province, Mt. Hwaya showed higher similarity of the species composition to that of the Mt. Jumbong.

Peritonitis is a serious problem in patients undergoing peritoneal dialysis. Rarely pneumatosis intestinalis can occur as a complication of this infectious process. Pneumatosis intestinalis is a potential life threatening condition with a challenging management. The mortality of peritoneal dialysis patients with pneumatosis intestinalis secondary to mesenteric ischemia is almost 100%. We describe a rare case of pneumatosis intestinalis in a peritoneal dialysis patient who developed Staphylococcus aureus peritonitis which was initially treated with appropriate antibiotics. Since initial response to therapy was not achieved, an abdominal computerized tomography was done which revealed a pneumatosis intestinalis. A laparotomy was performed and small bowel necrosis was seen. A segmented resection with ileostomy, jejunostomy was done. Though surgical treatment was performed, the patient died in 2 weeks after admission. Pneumocystitis intestinalis in peritoneal dialysis peritonitis is a uncommon complication which requires prompt evaluation to rule out mesenteric ischemia as it carries a high mortality and its management will be surgical.

Experimental evaluations for the iTECH beam System, which is invented for the purpose of making a lower height in steel structures, have been studied a lot for many years. In addition, they show the possibility of being developed as a new system when the iTECH beam system is applied in construction fields. However, the experiments were carried out without preceding theoretical analyses. Thus, it is intended to supplement some parts of the experiments by analyses and to provide the basis on future studies. iTECH Beam evaluated structural function through moment, shear, joint experiment and proposed formula. While this experiment, shear formula proposed assuming that steel web is all shown similar shear behavior about shear component element. This paper tries to verify assumption for analyzing shear behavior through FEA method.

A symmetric α-stable(SαS) noise density is considered as a model for impulsive noise channel. And, the structure and performance of a suboptimum detctor for discrete time signals in additive SαS noise are investigated. To illustrate the efficiency of the proposed nonlinear detector for a wide range of non-Gaussian noise distributions, the improved performance compared to that of a linear detector is studied using detection probability.

Objective : The purpose of this study was to assess the effect of acupuncture treatment for chronic headache patients using power spectrum analysis of the heart rate variability(HRV). Methods : 15 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as Chronic Headache patients. Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of acupuncture treatment were analyzed using power spectrum analysis of the HRV, HRV was recorded before and after acupuncture treatment. Results : HRV before and after treatment was compared after 8 weeks of acupuncture treatment. Increase in mean values of SDNN and RMSSD were observed but the increases were not statistically significants. Increase in mean values of TP, LF and HF were observed but, the increase was significant(p<0.05) only in TP. Conclusions : The results suggest that acupuncture treatment on chronic headache patients can increase the activity of autonomic nervous system. Further use of HRV for quantitative analysis of acupuncture treatment on autonomic nervous system related symptoms is suggested.

Thermogravimetric analysis and pyrolysis experiment were used as studying the effent of conversional level on the thermal degradation of HDPE. The wide conversional range in this work encompassed a change in the degradation mechanism. To accommodate this mechanism change, the data were treated as a pseudo first-order reaction. It was observed that the data conformed to a first-order fit at conversional range of 0.05∼0.98 with an activation energy of 376 kJ/mol. The lower activation energy occurring at lower conversion (0.01∼0.05) is attributed to scission of 'weak links' in macromolecles. The higher activation energy was similar to the carbon-carbon bond dissociation energy and is associated with random scission throughout backbone chain. The lower the conversional level, the more abundant the paraffinic hydrocarbon in product. To what extent this finding are influenced by limitation of terminate reaction of radicals.

Objective : Because the cause and etiology of chronic headache are not yet fully explained, the treatment of this symptom is not simple. In order to study the effectiveness East-West pain treatment on chronic headache, we evaluated its effect of pain alleviation and quality of life improvement on chronic headache patients who were treated with nerve block and acupuncture, and only acupuncture for eight weeks. Methods : 92 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified into two groups, nerve block and acupuncture group(EW group, n=49) and acupuncture group(E group, n=43). Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of two groups were analyzed using VAS scores and BPI(Brief Pain Inventory). Results : The VAS and BPI after four weeks of treatment showed significant improvement among two but differences between the three groups was statistically insignificant. The VAS and BPI of the EW group after eight weeks of treatment showed statistically significant improvement compared to the other two groups. Conclusion : The pain treatment for chronic headache might be contributed to improvement of quality of life as well as alleviation of pain of chronic headache patients. It was suggested that the West pain treatment in combination with East pain treatment might be an useful modality to improve the pain and quality of life in chronic headache patients.
