The effect of alkali treatment on the changes in characteristics, mechanical properties, and hand of polyester fabrics was studied. Two kinds of fabrics having different yarn deniers were treated varying weight loss. The results were as follows; 1. Changes in constructional characteristics by alkali treatment were: a decrease in weight & thickness of fabric, a decrease in yarn denier, a decrease in apparent density of fabric, an increase in porosity to air, and a change fiber surface. 2. As for the changes in mechanical properties by alkali treatment, findings were : an increase in WT, RT, MIU, LC, and WC, a decrease in LT, B,2HB, G,2HG,2HGS, MMD, SMD, and RC, ana an increase in drape. 3. Changes in hand by alkali treatment were: a decrease in KOSHI and HARE, an increase in FUUURAMI, SHARI, KISHIMI, and SHENAYAUASA, and an increase in T.H.V 4. In the case of the same weight loss, the hand of 40/24 fabric being composed of thinner yarns was better than the hand of 50/24 fabric. 5. When 50/24 fabric was treated to have the same weight with 40/24 fabric, so the yam deniers of two fabrics were the same, the hand of 50/24 fabric having larger weight loss was better than the hand of 40/24 fabric.

Bound lipids(BL) of naked barley(Hordeum vulgare L.) were extracted by different methods and the composition of BL was determined by the procedures of column chromatography, thin layer chromatography and gas chromatography. For the extraction, after free lipids were removed from barley flour by petroleum ether(PE) extraction and then BL were extracted from PE treated flour by the solvent systems of water-saturated butanol(WSB) at $25^{\circ}C$(WSB-LT) and at $95^{\circ}C$ (WSB-HT). BL were extracted by WSB-HT with higher extraction yield as 1.5% as dry basis of flour. The contents of neutral lipids(NL), glycolipids(GL) and phospholipid(PL) in BL were $20.7{\sim}35.5%$, $28.7{\sim}32.4%$, $32.1{\sim}50.6%$, respectively with particularly higher content of PL in WSB-HT as 50.6%. Digalactosyl-diglycerides $(40.2{\sim}44.8%)$, monogalactosyl-diglycerides $(20.3{\sim}31.1%)$, sterly glycerides$(11.2{\sim}15.2%)$ and cereb rosides$(11.6{\sim}12.9%)$ were observed in GL. Of the PL in BL, lysophosphatidyl choline, phosphatidyl choline and phosphatidyl serine, and phosphatidyl ethanolamine were the major components. The predominent fatty acids of NL, GL and PL were linoleic and palmitic acids, however, no significant difference was observed in the composition of fatty acids between two extraction methods.

Flupyrazofos (O,O-diethyl-O-(1-phenyl-3-trifluoromethyl-5-pyrazoyl)thiophosphoric acid ester) is a new organo-phosphorous insecticide. Flupyrazofos has exhibited excellent activity against diamondback moth (Plutella xylostella, DBM), and it is highly activity against rice armyworm(Pseudaleta separata) and cotton caterpillar(Palpita indicae). Flupyrazofos has then revealed outstanding both rapidity and residual action for DBM, although no systemic actions were observed and no cross-resistances were found to the resistance strains (Op-R, Py-R, IGR-R). Also, susceptibilities of five local strains to flupyrazofos were similar to those of the susceptible strain. These results indicate that flupyrazofos has considerable potential for controlling diamondback moth, rice armyworm and cotton caterpillar in field.
Objectives: This case study evaluated the effectiveness of Chengsimyeonja-tang-gamibang (Gamicheongsim-tang and Cheongsimsunhwal-tang) in a patient with a pontine hemorrhage and quadriparesis, dysarthria, and dysphagia. Methods: A patient diagnosed with a pontine hemorrhage was treated with Chengsimyeonja-tang-gamibang (Gamicheongsim-tang and Cheongsimsunhwal-tang) acupuncture, and moxibustion. The manual muscle test (MMT), modified Barthel index (MBI), National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS), Mini Mental State Examination-Korea (MMSE-K), and Articulatory Functional Ability of Achievement Scale were administered. Results: Improvements in the MMT, MBI, NIHSS, mRS, and K-MMSE were observed after the treatment. The MMT grade increased from Rt. 3/3- and Lt. 3/3- pretreatment to Rt. 4/4 and Lt. 4+/4+ post-treatment. The MBI increased from 10 to 50 post-treatment. The NIHSS decreased from 24 to 6 post-treatment, and the mRS fell from 5 to 4 post-treatment. Finally, the MMSE-K increased from 0 to 24 post-treatment. The Articulatory Functional Ability of Achievement Scale also improved. Conclusion: This study shows that Chengsimyeonja-tang-gamibang can be used to treat the symptoms of patients with a pontine hemorrhage.

Objective : We evaluated pseudoprogression (PsPD) following radiation therapy combined with concurrent temozolomide (TMZ), and we assessed pseudoresponse following anti-angiogenic therapy for patients with recurrent disease using the Response Assessment of the Neuro-Oncology Working Group. Methods : Patients who were pathologically confirmed as having high-grade glioma received radiotherapy with concurrent TMZ followed by adjuvant TMZ. Bevacizumab (Avastin) with CPT-11 were used as a salvage option for cases of radiologic progression. Magnetic resonance imaging (MRI) was routinely performed 1 month after concurrent radiochemotherapy (CRT) and every 3 months thereafter. For cases treated with the bevacizumab-containing regimen for progressive disease, MRI was performed every 2 months. Results : Of 55 patients, 21 (38%) showed radiologic progression within 4 weeks after CRT. Of these patients, 16 (29%) showed progression at second post-CRT MRI (etPD) and five (9%) showed improvement (PsPD). Seven of thirty-four initially non-progressed patients showed progression at the second post-CRT MRI (ltPD). No difference in survival was observed between the etPD and ltPD groups (p=0.595). Five (50%) of ten patients showed a radiological response after salvage bevacizumab therapy. Four of those patients exhibited rapid progression immediately after discontinuation of the drug (drug holiday). Conclusion : Twelve weeks following treatment could be the optimal timing to determine PsPD or true progression. MRI with gadolinium enhancement alone is not sufficient to characterize tumor response or growth. Clinical correlation with adequate follow-up duration and histopathologic validation may be helpful in discriminating PsPD from true progression.
We have made a survey of 40 patients in the university hospitals and oriental medical centers in Seoul from Sep. 1, 1997 to Mar. 1, 1998. We sampled 25 of them and the result shows that there were 12 MCA damaged patients(48%), 5 SAH(20%), 5 ACA(20%), 2 PCA (8%), 1 PCOA(4%). The number of MCA patients were the most. 1. As the cause of each disease, 4 of the 12 MCA damaged patients(33.35%) have infarction and cerebral hemorrhage, 2 of 5 SAH patients(40%) have cerebral hemorrhage and head injury, 3 ACA damaged patients have cerebral hemorrhage. 11 of 25 brain bloodvessel damaged patients(44%) were hemorrhage patients. 2. Rt. hemiparesis was the main symptom of 6 of 12 MCA damaged patients(50%) and 3 of 5 SAH patients(60%), and the main symptom of 3 of 5 ACA patients(60%) was Lt. hemiparesis. The main symptom of 13 of 25 brain bloodvessel damaged patients(52%) was Lt. hemiparesis 11 of them(44%) Rt. hemiparesis, and 1 of them(8.3%) Quadriplegia. 3. Language was the most well preserved function. 12 MCA damaged patients could understand language. 4. Retraction of shoulder girdle, among VIE flexor synergy, was the most frequent element because 9 of 12 MCA damaged patients had it. Among VIE flexor synergy, 5 SAH patient's most frequent synergy was Elbow flexion because all of them had it. All of 5 ACA damaged patients have shoulder girdle elevation, shoulder joint, hyperextension, abduction, and external rotation among VIE flexor synergy. 5. 7 of 12 MCA damaged patients(58.3%) were stereognosis handicapped patients, 3 of 5 SAH patients(60%) have handicap of position sense, light touch, and temperature, 3 of 5 ACA patients(60%) have position handicap. 13 of brain bloodvessel damaged patients(52%) have light touch handicap. 6. 8 of MCA damaged patients(66.7%) have facial palsy, 4 of SAH damaged patients(80%) have memory and action decline, and 3 of ACA damaged patients(60%) have action decline and facial palsy. The problem of Hemiplegia is very extensive from muscle weakness, atrophy, or deformation to psychical problems. Therefore physical therapists should have sufficient interest in psychological handicap as well as physical handicap as they deal with adult hemiplegia.
Angiomyoma is a rare, benign smooth muscle cell tumor. These tumors may be found anywhere in the body. They frequently occur in the lower extremities except venous type. Angiomyoma in the head and neck area is very rare, and only a few cases have been reported. A 63 year-old male patient visited to outpatient clinic due to size-growing nodule-like lesion in the Lt. alar area. Excisional biopsy was done for diagnosis. The lesion was totally excised with 2 mm safety margin. Frozen biopsy of the lesion was requested, and all resection margins were proved negative. To cover the raw surface, full thickness skin grafting was performed. The graft was harvested from Rt. posterior auricular area. Tie over dressing was applyed on Lt. alar area. The graft was well taken and healed without any complication in both short term and long term follow up periods of 2 weeks, 1 month, 2 months, and 6 months. Donor site completed healed without any complications. The leiomyoma is benign tumor originated from smooth muscle, and it can be classified into solid leiomyoma, angiomyoma, and epithelioid leiomyoma. Especially, the angiomyoma consists of smooth muscle cell and blood vessel, and it is originated from the tunica media of blood vessel. Angiomyoma alone frequently occurs in the lower extremities as solitary painless subcutaneous tumor. Venous type of angiomyoma in the oral cavity was reported in other references, but on the facial surface it may be the first case reported as paper. So this report can be very meaningful.

Objective: To investigate whether the diagnostic performance of CT angiography (CTA) could be improved by modifying the conventional criterion (anastomosis site abnormality) to diagnose hepatic artery occlusion (HAO) after liver transplantation (LT) in suspected patients with Doppler ultrasound (US) abnormalities. Materials and Methods: One hundred thirty-four adult LT recipients (88 males and 46 females; mean age, 52.7 years) with suspected HAO on Doppler US (40 HAO and 94 non-HAO according to the reference standards) were included. We evaluated 1) abnormalities in the HA anastomosis, categorized as a cutoff, ≥ 50% stenosis at the anastomotic site, or diffuse stenosis at both graft and recipient sides around the anastomosis, and 2) abnormalities in the distal run-off, including invisibility or irregular, faint, and discontinuous enhancement. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the conventional (considering anastomosis site abnormalities alone) and modified CTA criteria (abnormalities in both the anastomosis site and distal run-off) for the diagnosis of HAO were calculated and compared using the McNemar test. Results: By using the conventional criterion to diagnose HAO, the sensitivity, specificity, PPV, NPV, and accuracy were 100% (40/40), 74.5% (70/94), 62.5% (40/64), 100% (70/70), and 82.1% (110/134), respectively. The modified criterion for diagnosing HAO showed significantly increased specificity (93.6%, 88/94) and accuracy (93.3%, 125/134) compared to that with the conventional criterion (p = 0.001 and 0.002, respectively), although the sensitivity (92.5%, 37/40) decreased slightly without statistical significance (p = 0.250). Conclusion: The modified criterion considering abnormalities in both the anastomosis site and distal run-off improved the diagnostic performance of CTA for HAO in suspected patients with Doppler US abnormalities, particularly by increasing the specificity.
Experiments were conducted to study effects of different bioassay methods on toxicity to the German cockroach (Blattella germanica L.) ith six insecticides. For male adults, by dry film method, the {TEX}$LC_{50}${/TEX} value of chlorpyrifos. fenvalerate, propoxur, permethin, DDVP, and hydramethylnon was 1.79, 1.87, 3.04, 4.37, 32.72, and 270.81 ppm, respectively and the same tendency was shown in the female. For male adults, by topical micro-application method, the {TEX}$LD_{50}${/TEX} value of DDVP and fenvalerate, chlorpyrifls, permethrin, propoxur, hydramethylnon was 2.63, 3.79, 4.51, 6.73, 44.99 $\mu\textrm{g}$/g, respectively and the same tendency was shown in the female. From the diet toxicity method against male adults, the CT value (Concentration%$\times${TEX}$LT_{50}${/TEX}) showed that chlorpyrifos was rapid effective and hydramethylnon was residual effective.
Objectives. This study was carried out to analyze the hearingthreshold levels and relating factors of 1,048 workers with noiseinduced hearing loss$(D_1)$. Methods. We analyzed the hearing-threshold levels and relating factors of 1,048 workers with noise-induced hearing loss$(D_1)$ examined by the summary reports of specific health examination results of industries and personal reports of specific health examination results reported by 58 specific health examination institutes and 8 secondary pneumoconiosis examination institutes in 1996. Results. Among 1,048 workers at 510 workplaces, male workers were 1,009 (96.3%) and female workers were 39 (3.7%). The mean ages of workers initially exposed to noise and at present were 28.7 and 47.2, respectively. The duration of total exposure was 16.5 years. Average hearing-threshold levels analyzed by three-divided classification of the study subjects were 43.7dB(Lt) and 42.6dB(Rt). Those analyzed by six-divided classification were 50.5dB(Lt) and 48.6d8(Rt). Among workers with noise-induced shearing loss$(D_1)$, 16.3% was unilateral hearing loss and 84.6% was classified to compensation case. 8.8%(Rt) and 10.2%(Lt) of them were suspected to be conductive hearing loss by differences of air-bone hearing-threshold levels. Hearing-threshold levels of workers in manufacturing industry were significantly increased during the short exposure compared with the levels in mining industry. Among manufacturing industries, hearing-threshold levels of workers in trailer and other transportation equipment manufacturing industry were significantly increased. Age and duration of total noise exposure were not significantly related to the average hearing-threshold levels analyzed by three-divided classification. Hearing-threshold levels of female workers were significantly increased during the short exposure compared with those of male workers. Hearing-threshold levels of workers at the high risk group, ages of 20s, 30s and total exposure duration of less than 10 years, were not significantly increased compared with those of the other groups. However, they were exposed at young ages. The 3 leading industries of workers at high risk group were trailer and other transportation equipment manufacturing, automobile manufacturing and assemble-metal manufacturing industries. Conclusions. This study was the first nationwide analysis of the hearing-threshold levels and relating factors of workers with noise. induced hearing loss$(D_1)$. We found the differences of the real number by the statistics of the department of labour and the expected number of worker' s compensations for occupationally-induced hearing loss estimated by this study. According to the results of this study, we should carefully examine the methods to narrow this difference.
