This study examines the adequacy of odor intensity, dilution factor for complex odors, linkage of substance concentrations of designated odor substances, and adequacy of emission limits for aromatic hydrocarbons and esters compounds, ketone, 4 fatty acids and isobutyl alcohol. In addition, this study proposed a proposal to improve the standard value of individual material standard. The correlation and adequacy of mutual reference values were examined using the correlation between odor intensity, material standard, dilution factor. 15 and 20 of dilution factor are enhanced levels compared to 2.5 and 3.0, which are the odor intensity standards. Butyl acetate is a weakened standard, with a large change in substance level and stronger than dilution factor. Propionic acid and Butyric acid were found to be the most potent concentration levels. From the correlation equation, the substance concentration corresponding to the basic standard of odor intensity was calculated, and it was partially different from the current substance concentration standard. In order to examine the adequacy of the proposed standards, the odor intensity was calculated for the semi-industrial and industrial areas using the relationship between the material standard and the dilution factor, and almost all substances had odor intensity of 2.5 and 3.0. 본 연구에서는 지정악취물질중 방향족 탄화수소, 케톤류 및 에스테르, 4개의 지방산과 아이소부틸알콜, 총 10 종에 대하여 악취관리 수단으로 사용하는 악취강도, 복합악취에 대한 희석배수, 지정악취물질의 물질농도 기준간의 연계성 및 배출허용기준의 적정성을 검토하고, 개별 물질농도의 기준치 개선(안)을 제안하고 자 하였다. 악취강도와 물질농도, 희석배수, 그리고 물질농도와 희석배수간의 상관관계식을 이용하여 상호 기준치의 연계성과 적정성을 검토하였다. 일반적인 악취강도의 규제 기준치인 2.5와 3.0에 비해 희석배수 15와 20은 강화된 수준이며, 물질 기준인 경우는 변화폭이 크고 희석배수보다 더욱 강화된 수준으로 뷰틸아세테이트는 약화 기준치이며, 프로피온산과 뷰틸릭산은 가장 강화된 물질 농도수준인 것으로 나타났다. 상관관계식으로부터 악취강도의 기본 기준치에 해당하는 물질농도를 산출하였으며, 현 악취방지법에 기준 되어진 물질농도와는 일부 다르게 나타났다. 제안되어진 기준들의 적정성 검토를 위하여 희석배수와 물질농도의 관계식을 이용한 검토와 결과 값을 통해 준공업지역과 공업지역에 대해 악취강도를 산출한 결과 거의 모든 물질이2.5와 3.0의 악취강도를 갖는 것으로 나타났다.

This study was aimed to evaluate the relationship between the concentration and dilution factor (ratio) using the Air Dilution Olfactory Method, which is suggested in the Standard Method of Odor Compounds, by measuring dilution factor for m-xylene, toluene, methyl ethyl ketone, methyl isobutyl ketone, and butyl acetate. For the measurement, 18 panelists were selected by several criteria through panel test. Panelists chosen for their closely similar sensitivities provide more reproducible values. The estimation showed that the correlation of the concentration with dilution factor for the 5 compounds including the m-xylene, toluene, methyl ethyl ketone, methyl isobutyl ketone, and butyl acetate can be reasonably expressed by the equation log C = AflogD + F (Af : material costant, F : constant). The result of this study is suggested to be used as a base data for research on measures to improve the regulation standards for complex odor concentration on site boundary in operation, as well as a correlation between the concentration and dilution factor for the designated foul odor substances, and their characteristics. 본 연구에서는 현재 악취공정시험방법에서 제시하고 있는 공기희석관능법에 의한 희석배수와 지정악취물질중 m-자일렌과 톨루엔, 2종의 케톤류, 뷰틸아세테이트, 총 5종의 각 개별적 물질농도와의 관계를 살펴보고자 개별적 물질농도에 대한 희석배수를 측정하였고 물질농도와 희석배수간의 상관관계 특성 및 관계식을 산출하여 제시하였다. 지정악취물질농도와 희석배수의 상관관계는 log C = AflogD + F (Af : 물질별상수, F : 상수)에 의해 적합하게 표현되었으며, 각 물질의물질별 상수값을 제시하였다. 또한 총 12개의 지정악취물질농도와 희석배수의 상관관계식을 이용하여 부지경계선에서배출허용기준으로 규정하는 희석배수 기타지역 15, 공업지역 20 에 해당하는 개별물질별 물질농도를 산정하여 제시하였다. 희석배수를 기반으로 계산한 농도와 현행물질별 기준농도를 비교한 결과, 12가지 물질중 암모니아의 농도 기준치는낮게 설정되어 있으며, 황화수소와 뷰틸알데하이드, 트리메틸아민의 경우는 기준치가 약간 높게 설정된 것으로 추정된다.본 연구결과는 현재 적용되고 있는 부지경계선에서의 복합악취 농도 규제기준에 대한 개선방안 및 지정악취물질들의 물질농도, 희석배수간의 관계 및 특성연구 등의 기초 자료로 사용될 수 있을 것으로 판단된다.

The purpose of this study is to propose a supplement to current freight demand model by analyzing factors that influence the generation of empty truck movements in regional and urban realms. To achieve this, we examined the relation between the number of empty truck trips and various generators such as truck attributes, origin type and attributes, destination type and attributes, and commodity type. We structured the ordered logit model using 2011 Korea Transport Database (KTDB) data to analyze the generator characteristic of empty truck movements in regional and urban settings. According to the results, the characteristics of regional and urban empty truck movements differed depending on truck attributes, origin type and attributes, destination type and attributes, and commodity type. 본 연구는 지역적 범위에 따른 화물자동차의 공차통행 발생요인을 검토함으로써, 기존 화물수요모형의 한계를 제시하고자 하였다. 지역간 및 대도시 화물자동차의 공차통행 발생요인을 검토하기 위하여 화물자동차 속성, 출발지및 도착지 특성, 그리고 운송품목의 유형을 고려한 서열로짓모형을 추정하였으며, 이를 통하여 화물자동차의 공차통행 발생에 영향을 미치는 다양한 요인들을 정량적으로 검토하였다. 분석결과 지역간 화물자동차의 공차통행 발생요인과 대도시 화물자동차의 공차통행 발생요인은 서로 상이한 것으로 나타났다.

To evaluate change of serum beta₂-microglobulin concentration (sβ₂-MG) and the usefulness of sβ₂-MG and sβ₂-MG/serum creatinine concentration (sCr) ratio in various renal diseases, sβ₂-MG and sCr were measured in 25 normal controls and 90 patients of various renal diseases (16 cases of glomerulonephritis, 12 cases of acute renal failure, 8 cases of chronic renal failure, 24 cases of nephrotic syndrome, 15 cases of tubulointerstitial diseases and 15 cases of lupus nephritis) using Phadebasⓡ Beta₂-Micro Test kits. The results were as follows; 1) In normal control, the mean value of sβ₂-MG was 1.65±0.41 ㎎/ι and the mean value of sβ₂-MG/sCr ratio was 0.14±0.05. 2) In various renal diseases, the mean value of sβ₂-MG was 6.74±5.47 mg/ι. The mean value of sβ₂-MG/sCr ratio was 0.24±0.11 and significantly elevated than that of normal contro1. (P〈0.05). 3) The correlation between sβ2-MG and sCr in glomerular and tubulointerstitial disease was log sβ₂-MG=0.90 log sCr-0.48 and its correlation coefficie5). 4) In glomerular disease, the correlation between sβ2-MG and sCr was log sβ2-MG=0.89 log sCr-0.46 (r-0.76) and in tubulointerstitial disease, it was log sβ2-MG=0.95 1og sCr-0.59 (r-0.87). There was no significant difference between the two groups (p〈0.05). 5) Among 32 cases of glomerular and tubulointerstitial disease patients, whose sCr was within normal range, 17 cases showed elevated sβ₂-MG. The mean values of sβ2-MG/sCr ratio in these patients was 0.30±0.14 and significantly elevated than that of normal control (p〈0.05). 6) In 15 cases of lupus nephritis, 12 cases showed elevated sβ2-MG with normal sCr and 12 cases showed elevated sβ₂-MG/sCr ratio. With above results, It was found that the sβ₂-MG can be used as an index of glomerular filtration rate as in the case of sCr and thats sβ₂-MG/sCr ratio can be used as a tool in early detection of slightly decreased glomerular filtration rate and in detection of the renal disease of increased β₂-MG production.

With the improvement of hemodialysis, the coursc of thc discase in patient with endstage renal disease has been clearly improved. Nevertheless, among several shortcomings to our present mode of renal replacement therapy, cardiovascular complications have been the leading cause of morbidity and mortality. Several factors such as anemia, arteriovenous shunting of blood, intermittent extracorporeal circulation and hypartension may be contri-buting. But little is known about the quantitativc cardiac hemodynarnic charact$quot;ristics occurred during hemodialysis. The purpose of this study is to observe the sequential hemodynamic changes before, during and after the hemodialysis and to investigat: reliable parameters in the detection of ventricular dysfunction. In the present study, equilibrium radionuclide cardia.c angiography was performed and left: and right ventricular volume indices, ejection phase indices of both ventricular, perfo-ramanc were rneasured in the 16 stable patients with chronic renal failure treated with maintenance hemodialysis sequentially i.e. beforc, during (carly and late phase) and after the hemodialysis. The results obtained were as follows; 1) The indices of the left ventricular function were not changed during the hemodialysis but increased after the hemodialysis. 2) The indices of the right ventricular function(EF, SVI) wcre significantly decreased in the early phase (15, 30 minutes after starting extracorporeal circulation) but recovered after the hemodialysis, 3) The ratio of right ventricular to left ventricular ejection fraction was significantly decreased in the early phase and the lung volume indices wcre significant1y increased at the same phase. As a conclusion, hemodiaiysis irnproves left vcntricular function maybe du to increased contractility, and effects on the right ventricular function maybc due to the increascd lung volume in the early phase of hemodialysis.
