Objectives: Korean regression models for spirometric reference values are different from those of other ethnic groups. The purpose of this study was to evaluate discordance in spirometric interpretations based on using Korean reference equations versus non-Korean reference equations. Methods: Spirometry was performed on 825 Korean male workers from April 2009 to November 2011. The spirometric patterns and disease severity were evaluated using two Korean equations (Choi’s and Lee’s) and three equations for Caucasians (NHANES III, Morris’s, and Knudson’s), and the results of Choi’s equation were compared with the non-Korean equations. The spirometric patterns were defined as normal, restrictive, and mild and moderate obstructive. Results: The mean differences in the FEV1% and FVC% between the two Korean equations were 2.0 ± 1.3% and 3.5 ± 2.2%, respectively. Morris’s equation had the greatest difference in the FEV1% from Choi’s equation: 32.9 ± 8.5%. Knudson’s equation had the greatest difference in the FVC% from Choi’s equation: 10.5 ± 6.5%. Conclusions: The two Korean equations shared similar characteristics of spirometric interpretation. The spirometric interpretations of Choi’s equation were significantly different from those of Morris’s equation and Knudson’s equation.

The metal-thin insulating film-semiconductor structure is currently receiving much attention in solar cell studies. In this a MIS solar cell consisting of aluminum on single and poly silicon with an interfacial oxide layer(∼20Å) have been fabricated by vacuum evaporation method and found a good reproducibility. Recent studies show the importance of surface and interfacial oxide thickness. An interfacial of 20∼30Å is optimum and may be achieved by furnace heating to 600℃ in 800cc/min O₂flow. These cells have good rectification with forward and reverse voltage under dark condition. The best Al/p-Si Si solar cell has an open circuit voltage Voc=0.4V, short circuit current density Isc=30mA/㎠, fill factor FF=0.58 and conversion efficiency η=10% for single crystal, and Voc=0.33 V, Isc=30mA/㎠, FF=0.49 and η=5% for poly crystalline silicon substrates for 70mA/㎠ irradiation of AM₂.

이종호,최병대,이강호,이근태,김태수 國立統營水産專門大學 附設 水産科學硏究所 1989 수산과학연구소보고 Vol.1 No.-

쥐치의 향기성분을 동정하기 위하여 Likerson형의 연속증류추출 및 탄산가스추출법을 이용하여 휘발성 성분을 동정하였다. 그 결과 중성획분에서 55 성분, pherol성획분에서 4 성분, 염기성획분에서 13 성분 및 ㅅ산성획분에서 10 성분이 분리·동정되었고 중성획분에서는 가열·배소 후 propanol, butanol, octanol, dodecanol등의 alcoholfb 그리고 pentanal, hexanal, 2-methyl-l-propanal, heptenal등의 aldehyde의 함량이 크게 증가하여 flavor 형성에 크게 기여할 것으로 생각되어 진다. 분리·동정된 phenol류는 분자량(m/e) 100~160 정도로 나타났으며, 염기성획분에서는 2-methylpyrazine, 2,5-dimethylpyrazine, 2-ethyl=3,5-dimethylpyrazine 등과 2-methylpyridine등이 동정되었다. 이들과 함께 중성획부에서 동정된 furan류가 가열온도의 증가와 함께 그 함량이 증가하였다. 산성획분에서는 배소시료 구분에서 isoaproic acid 및 caproic acid의 함량이 많았다. Volatile compounds were collected by simultaneous distillation extraction and carbon dioxide method, and analyzed by GC and GC-MS. The neutral fraction obtained from the whole steam volatile concentrate 55 kinds of components, phenolic fraction had 4 kinds of components, basic fraction had 13 kinds of components and 10 kinds of components were in acidic fraction. Alcohols, propanols, butanols, octanols, dodecanols etc. and aldehydes, pentanals, hexanal, 2-methyl-1-propanal, heptenal etc. were highly increased after boiled and roasted. And these compounds were contributed to formation of filefish flavor. The molecular ion peak of phenolic fraction was generally appeared in the range 100 to about 160. From the basic fraction, 2-methylpyrazine, 2,5-dimethylpyrazine, 2-ethyl-3,5-dimethylpyrazine and 2-methylpyridine were identified. The contents of basic compounds and furans obtained from the neutral fraction were increased at the higher heating temperature. The flavor of acidic fraction was influenced by the low molecular as isovaleric and valeric acid.

To investigate the effects of short-term administration of DDB(Biphenyl Dimethyl Dicarboxylate) for decreasing elevated serum aminotransferase levels in chronic liver diseases, authors applied 3 capsules of DDB per day at each meal time for 35 patients and compared with 35 patients treated with other conservative management. The following results were obtained. 1. Serum alanine aminotransferase (ALT) levels significantly decreased from 247.1± 180.0 IU/L of pretreatment level to 96.6±126.0 IU/L, 61.1±62.7 IU/L and 38.0±26.8 IU/L after 1, 3 and 6 months of treatment(p<0.05) and effective rates were observed in 60.0%, 71.4% and 88.6% of patients after 1, 3 and 6 months of treatment. 2. Serum aspartate aminotransferase (AST) levels decreased also significantly from 167.8±96.9 IU/L of pretreatment levels to 124.4±155.0 IU/L, 77.9±49.6 IU/L, 60.6± 46.9 IU/L after 1, 3 and 6 months of treatment(p<0.05), but decreasing pattern of serum AST was less significant than that of serum ALT. 3. No significant difference were observed in the serum ALT and AST changes according to the cause and duration of hepatitis. 4. No significant adverse effects were observed in whole patients treated with DDB. It is suggested that small dose administration of DDB is effective for decreasing serum aminotrans ferase levels in chronic liver disease in which other conservative management was not effective.

In department of obstetrics and gynecology, ovarian tumors are common and very variable in type. The origin of varian tumor is poorly understood, because of complexity of ovary in function, anatomy, and embryology. There are variable different classification of the ovarian tumor, depending on whether the criteria employed are based on macroscopic appearance, microscopic finding ,clinical behavior or histogenesis of the tumor. But there is now general agreement that classification of ovarian tumor should be based on the presumed cell of origin. A total of 463 cases of ovarian tumor was obtained from the pathology file of the department of pathology, College of Medicine, Chungnam National University during a period of 7 years beginning from January 1977 to December 1982. The results were followings; 1. These tumors consisted of 395 cases(85.3%) of benign tumors and 68 cases(14.7%) of malignant tumors. 2. In benign tumor, cystic teratoma(188 cases=47.6%) ranked first followed by serous cystadenoma(83 cases=21.0%) and mucinous cystadenoma (77 cases=19.5%), and fibroma (29 cases=7.3%). 3. In malignant tumor, metastatic carcinoma(20 cases=29.4%) was the most frequent, followed by mucinous cystadenoma, borderline(10 cases=14.7%) and serous cystadenocarcinoma (9cases=13.2%), and dysgerminoma(8 cases=71.8%). In addition, serous cystadenoma, borderline was 4 cases(5.9%), cystic teratoma with malignant change was 3 cases(4.4%) 4. Benign tumor measured 8.9㎝ in mean size of maximum diameter and malignant tumor, 13.5㎝ in mean size of maximum diameter. 5. No site predilection was noted and bilateral involvement was most frequent in metastatic carcinoma 8 cases(40%), followed by serous cystadenocarcinoma 2 cases(22.2%), serous cystadenoma 8 cases(9.6%), and cystic teratoma 18 cases(9.6%). 6. Benign tumor were most prevalent during the reproductive period, but malignant tumor were prevalent in older age group. 7. Papillary growth and psammoma bodies were more frequently found in serous type than in mucinous type. But multilocular change was more frequently found in mucinous type.

The temperature dependence of the ultrasonic velocity of 10 MHz and the absorption coefficient in the 10-30MHz range by the pulse echo method were determined in lead germanate single crystal. The velocity of longitudinal 10 MHz ultrasound along the c axis changed anomalously at the phase transition point and the jump was approximately 50m/sec. Near Curie point, the relaxation time and the kinetic coefficient of electric polarization from the Landau-Khalatnikov theory were calculated as ?? sec and ??, respectively. At room temperature, the viscosity tensor were measured as, ?? in the MKS units.
