For the purpose of obtaining of an effective biological monitoring data in terms of evaluation the health consequences of lead absorption, the female workers in the electronic industry who have been exposed to low-level lead occupationally were chosen as the subjects of our studies. We observed the 9 parameters in not only 305 lead-exposed female workers who have been exposed to lead occupationally also 254 normal female subjects who have not been exposed to lead occupationally. The parameters chosen for this study were as follows, blood lead (PbB), urine lead (PbU), δ-aminolevulinic acid in urine(ALAU), coproporphyrin in urine(CPU), zinc protoporphyrin in whole blood(ZPP), hemoglobin(Hb), hematocrit(Ht), δ-aminolevulinic acid dehydratase(ALAD) activity & ALAD activity ratio(A/R; absorbance at substrate pH 6.6/absorbance at substrate pH 5.8). The results obtained were as follows: 1. The average age of the lead-exposed female workers in the electronic industry and in the normal female subjects were 20.5±4.2 years and 21.7±3.5 years, respectively. 2. The average work duration of the lead-exposed female workers in the electronic industry was 26.4±19.4 months 3. The mean value of PbB of the lead-exposed female workers in the electronic industry and in the normal female subjects were 30.18±6.64㎍/100ml and 21.61±3.84㎍/100ml respectively. 4. In the lead-exposed female workers of the electronic industry and of the normal female subjects, the mean value of ZPP were 36.22±0.69㎍/100ml and 24.64±7.21㎍/100ml, respectively 5. In the lead-exposed female workers of the electronic industry and of the normal female subjects, the mean value of Hb were 13.98±0.57g/100ml and 14.09±0.66g/100ml, respectively. 6. The mean value of the lead-exposed female workers in the electronic industry were 55.07±17.61㎍/1 for PbU, 1.93±0.69mg/1 for ALAU, and 49.74±22.79㎍/1 for CPU, while in the normal female subjects, 44.27±15.76㎍/1 for PbU, 1.46±0.55mg/ 1 for ALAU, and 38.66±17.99㎍/1 for CPU. 7. Among various pairing of the parameters of lead exposure in the female lead-exposed workers and in the normal female subjects, the correlation between PbB and ZPP showed the highest coefficient value.

Bis-Diazotized Benzidine에 의한 연속 및 동시흡착법에 의하여 Tuberculin PPD로 감작된 적혈구를 이용한 혈구응집반응의 민감성

김택선,정상인,최철순,양용태 중앙대학교 의과대학 의과학연구소 1984 中央醫大誌 Vol.9 No.3

Passive haemagglutination test(PHA) using sheep red blood cells(SRBC) sensitized with soluble antigens by means of coupling agents, i.e., tannic acid, bis-diazotized benzidine(BDB), chromic chloride, glutaraldehyde, and so on, provide an extremely sensitive technique to detect a minute quantity of serum antibody as low as 0.01㎍. It also has advantage over agglutination and precipitation tests in that if it is transferred either to hemolysis test(PHL) or to inhibition test(PHI), soluble antigen-antibody complexes and incomplete or hapten antigen-nonprecipitating antibody complexes that are not detectable by other tests can be demonstrated. This study was undertaken to determine the optimum amount of BDB and tuberculin PPD antigen for consecutive and simultaneous coupling of SRBC in conjunction with the sensitivity of the PHA test. In addition, the sensitivities of PHA and PHL test were compared and the PHA units of antibody and diluents for tuberculin PPD antigen for PHI test were discussed. The results are summarized as follows: 1. The optimum amount of BDB for consecutive and simultaneous coupling of 0.2ml of 2.5% SRBC were 20㎍ and 13㎍, respectively, and the optimum amount of tuberculin PPD antigen were about 125㎍ and 250㎍ respectively. The optimum ratios between BDB and tuberculin PPD antigen for consecutive and simultaneous coupling were 1:6.3 and 1:19.2, respectively. 2. In the consecutive coupling, the PHA titre was linear to both BDB and tuberculin PPD concentrations, whereas in simultaneous coupling it was affected by the level of tuberculin PPD but not by that of BDB from 5㎍ to 13㎍. 3. Using SRBC sensitized consecutively with tuberculin PPD or sensitins prepared from four species of mycobacteria the homologous PHL tests were sensitive than the PHA tests by 1:2 to 1:4 dilutions, and the end-point of PHL test was more clear-cut than that of PHA test.

찹쌀, 보리쌀, 밀가루, 고구마로 제조한 3개월 숙성 고추장의 alcohol과 ester류를 GC로 분석 동정한 결과는 다음과 같다. 시험 고추장에서 12종의 alcohol과 16종의 ester이 동정되었으며 면적 비을은 alcohol류 0.31~l.75%, ester류 33.06~97.16%였다. Alcohol은 밀가루, ester은 고구마 고추장에서 면적 비율이 높았고 보리쌀 고추장은 이들 성분이 가장 낮았다. 밀가루와 고구마 고추장은 12종의 alcohol이 검출되었으나 보리쌀 고추장은 5종으로 적었다. n-propylalcohol, active amyl alcohol, n-cotyl alcohol, β-phenylethyl alcohol은 모든 고추장에서 동정된 공통이 성분이다. Active amyl alcohol과 n-propylalcohol은 보리쌀 고추장을 제외한 시험 고추장에서 면적 비을이 높은 alcohol에 속하였다. Ester은 밀가루와 고구마 고추장에서 16종이었으나 찹쌀 고추장은 12종으로 적었다. n-butyl acetate, ethyl caprate, ethyl caprylate, ethyl levulinate, ethyl benzoate를 제외한 11종의 ester은 시험 고추장의 공통 성분이었다. Ethyl linoleate는 면적 비을이 19.08~55.06%로 alcohol과 ester중 가장 높은 주성분이었다. Ester중 ethyl oleate, ethyl palmiate, ethyl linolenate, ethyl myristate, ethyl laurate도 면적 비을이 높아 고추장의 주ester성분으로 나타났다. 이들 성분 중 ethyl linoleate는 밀가루, ethyl linolenate는 고구마, ethyl oleate와 ethyl palmitate는 찹쌀 고추장에서 면적 비율이 높았다. Kochujangs were made from a glutinuous rice, barley, flour and sweet potato as a starch source and fermented for three months. Alcohol and ester components of kochujangs were identified with GC. Twelve alcohols and sixteen esters were found in kochujangs. As a peak area 0.31-1.75% of alcohols and 33.06-97.16% of esters in volatile components were found. Alcohols were high as a peak area in kochujang made of flour while esters were high in kochujang made of sweet potato. Only five kinds of alcohols were found in kochujang made of barley. n-Propyl alcohol, active amyl alcohol , n-octyl alcohol and β-phenyl alcohol were found in all treatment. There were high peak area of active amyl alcohol and n-propyl alcohol except kochujang made of barley. Ethyl linoleate(19.08-55.06%), ethyl oleate, ethyl palimitate, ethyl linolenate, ethyl myristate, and ethyl laurate were major components in esters. There were high peak area of ethyl linoleate in kochujang made of flour, ethyl linolenate in kochujang made of sweet potato, and ethyl oleate and ethyl palmitate in kochujang made of glutinuous rice.

This study intend to develop the model to estimate the effect of the highway and Railway on the land value such as total land value and manufacturing land value. The main methodology is multiple regression model including demand factor, supply factor, Hansen's accessibility and agglomeration factor. The results are as followings; First, The goodness of fit is very high(R^2=0.79∼0.93) and the stability of the parameters is very high in the two models. It is the demand factor, the accessibility of highway and railway, and the agglomeration factors that have an effect on land value. Supply factor is not important to the land value. Demand factor like population have a greater effect on land value than supply factor. Second, the construction of highway and railway have a great influence on the land value. Especially the construction of highway is very important factor to manufacturing land value. The effect of time and distance constraint in accessibility on the total land value and the manufacturing land value is different. The time and distance constraint in accessibility was working sensitively. Finally the agglomeration factor like the land value of Metropolitan area had a positive effect on total land value but didnot have a negative effect on the manufacturing land value.

ABSTRACTThe purpose of this study is to improve a land category system by researching on the actual conditions. In order to acheive the goal, study methods are as follows: First, to refer to literature on general land category systems. Second, to take material survey and on-the-spot study of land category system especially focused on housing site and miscellaneous land. Third, asking questions to public officials who are engaged in the ministry associated with land.Based on the above analysis the result is as foliws. First, there is the necessity of classifying and adjusting land category system on a realistic basis. Second, the ministry concerned with land is making good use of land category system. Third, it is necessary to improve the land category system especially on housing site and miscellneous land which consist of most part of urban area.To make summary of this study is that exsisting 24 land category system is so insufficient to reflect various characteristics, that it needs to be improved particularly on housing site and miscellneous land. Therefore if land category system change as above, the management of land will be improved so that land categories have role as a source of land information.

Some selected natural zeolites obtained from Kyungpook coastal area were modified by HCI, NaOH and NH_4OH solutions and exposed to the atmosphere of various vapour pressure within the desiccator. Generally, silica gel exhibited as good moisture adsorbent at high humidity and as poor adsorbent at low humid atmosphere. However, moisture adsorption capacities of mordenite such as Na^+-K_111, NH_4^+-K_111, Na^+-Y_11 exceeded the silica gel at the lower moisture pressure than 16 torr. NH_4^+-MOrdenite proved itself to be best adsorbent in the closed system whose moisture pressure diminished as the time eclipsed. This system was most closely simulated to the working conditions of those commercial dryer in the package.
