문수형,이호원,김유나 한국공업화학회 2015 한국공업화학회 연구논문 초록집 Vol.2015 No.0

스코리아의 흡착속도에 대하여 1 차 흡착 속도모델을 적용한 결과, 대부분의 스코리아 시료에서 완전한 선형관계가 성립하지 않았으나, 2차 흡착 속도모델을 적용한 결과 모든 스코리아에서 좋은 선형관계를 보였다. 내부확산모델을 적용한 결과, 3개의 직선영역으로 도시할 수 있었다. 첫 번째 직선은 빠른 흡착이 일어나는 단계로 중금속 용액이 경계층으로의 확산과 경계층에서 입자 표면으로의 외부확산이 일어나는 단계이고, 두 번째 직선으로 도시된 부분은 세공내 확산에 의해 흡착속도가 지배되는 단계라 할 수 있으며, 세 번째 직선 영역은 흡착질인 남아있는 중금속 농도가 매우 낮은 상태에서의 세공내 확산으로 확산 속도가 감소하는 단계로 구분할 수 있었다. 3 개의 직선 영역에서의 반응속도 상수를 구한 결과, 빠른 흡착반응이 진행되는 첫 번째 직선영역의 반응속도상수가 두 번째 및 세 번째 직선영역보다 반응속도 상수가 매우 큰 것으로 나타났다. 이러한 결과로부터 흡착 초기의 빠른 흡착단계는 중금속 이온의 외부 확산 단계이며, 두 번째 및 세 번째 직선영역으로 나타내는 흡착은 느린 흡착반응으로 내부확산인 세공내 확산 단계로서 스코리아의 흡착은 세공내 확산이 흡착속도를 지배하는 율속단계임을 확인할 수 있었다.

We'd experienced a case of primary hepatoma at medical department, Dae han Kyoyuk Ins. Company January 1985. As it was found very early stage, we made out the case long term-survival possibility unexpectedly. The conclusions we gained, making comparative-analysis of ultrasonic view and operation's view are as follows; 1. By ultrasonography, echogenicity of tumor was increased type as compared with liver parenchyme. 2. The margin of the primary hepatoma by ultrasonography encapsulated well and the extraction after operation was same. 3. The boundary of tumor was clear. 4. The space-occupying lesion in liver was solitary. 5. The affected site was left lobe of the liver. 6. We couldn't discover a little fluid echo in upper abdomen on the ultrasonography, but could see in the cul-de-sac area and it accorded with the gross finding during laparotomy. 7. The case was cholangiocarcinoma in view of pathologic histology. 8. After the operation of lobectomy. the prognosis which was passed a months was very satisfactory and she exists until present.

Heavy-Metal Adsorption Characteristics of Scoria Distributed over the Earth Surface of Jeju Island

문수형,이호원,김승건 한국공업화학회 2023 공업화학 Vol.34 No.1

In this study, we investigated the various adsorption factors influencing the adsorption of heavy metal ions based on the study of the composition and physicochemical properties of scoria dispersed throughout Jeju Island. Analysis of the distribution characteristics of scoria samples collected from five areas of Jeju showed that reddish-brown‐colored scoria were predominant. Analysis of scoria collected from Jeju Island showed that its mineral components are ordered as follows: SiO2 > Al2O3 > Fe2O3 > CaO and MgO. The experimental data did not show a linear relationship in the pseudo-first-order adsorption kinetics. In contrast, a pseudo-second-order model yielded a positive linear relationship, and this model was subsequently used. It could be concluded based on an intraparticle diffusion model indicating linear relationships that the capture of metal ions on scoria is dominated by the primary adsorption step.

Congenital hereditary disease is in devided into Infantile type and Adult type, Adult type is hidden for many years and keeps normal renal function till middle age. Cyst is stimultaneously made in both sides and becomes lowered in renal function in 30's to 40's. Infantile type is generally born with the big kidneys, renal failure, undergrowth of intrahepatic bile duct. Both infantile and childhood type have ureteral dilatation and portal hypertension In infantile type, it is mostly developed into renal failure, but generally faces death as a result of hepatic disease. The reason of death is that an abnormal condition of recessive autosome affects the liver and kidneys. While the incidence of infantile type is rare as $0.017{\sim}0.07%$ and it is autosomal recessive heredity, Adult type can rarely exist in infantile period. Though it exists in middle period, 50% of patients can live for 2-4 years after the first symptom incidence and 25% can less than 2 years. It is hard to cure completely in medicine and surgery. Three difficulties in familial incidence are comparative decrease of the donor who have no affection on renal transplantation. For another consideration it is to show the family history for several generations. We, the Med. Dept. of Dae Han Kyouk Life Insurance Co. Ltd., used the ultrasonic apparatus in diagnosing the one case of adult type bilateral polycystic kidney and then doubted the family history. As a result of inspecting the family we experienced bilateral polycystic kidney from 3 persons out of 4 who can be inspected. The results are as follows: 1) We could confirm the polycystic kidney from 3 persons out of 4(75%). 2) Then when they came for check up, chief complaint was the pain in all 3 cases(100%). 3) Accompanying disease was hypertension in 2 cases(67%). 4) In early disease incidence, we couldn't observe the specific change in pathological opinion. 5) All 3 cases are not accompanied with cystic lesion in liver, spleen, pancreas.

Among the person who want to insure, there are not only fair persons who want to become the insurance with not realizing that one was not infected with certain disease but also someones on purpose to overcome the disease through the insurance company with be recognized by oneselves. However, it was found that the ultrasonography and exact effects of medical examination with the existing medical equipments of the insurance company could not be expected. We present some several proven examples for the purpose of getting the advanced effects in medical examination by utilizing the ultrasonic device which is not harmful to human body presently as far as known. We could find affirmation through the check of ultrasonography from 907 cases, in our Department of Medical selection that many portion of the cases checked the medical examination have the present condition of illness even though they enjoy social life with good health and finally the conclusions we have learned are as follows; The aged cases show the increase of rate of possessing disease and man shows 2.2 times of possessing disease than woman. Fatty infiltration of liver take portion of 74.7% from the case checked. 12 cases of cholelithiasis are not conscious of symptom at all. Through the check of ultrasonography in obstetrics and gynecology, myoma uteri be showed high rate of 72.2% from the case of possessing disease. In Case of the potential pregnancing woman it made clear to find pregnancy which was undistincted still more also know the existence and nonexistence of fetal death when pregnancy expected.
