이홍석,이영호,이석하 대한민국 학술원 2011 학술원논문집 : 자연과학편 Vol.50 No.2

콩은 단백질 공급을 비롯하여 영양가가 높아 예로부터 우리의 중요 식품으로 널리 다양하게 이용하여 왔을 뿐 아니라 지속적인 밭작물 재배를 가능케 하는 중요한 역할을 하여 왔으며, 최근에는 건강식품으로 또 친환경 농업 작물로 주목을 받고 있다. 콩은 세계적으로 99,501천ha에서 223,185천톤(2,243kg/ha)이 생산되고 그의 35.5% (35,130백만불)가 수출되고 그 중 43%는 미국 콩이, 96.5%는 미대륙 생산 콩이 수출되고 있으며, 수입의 반 정도는 중국이, 37.6% 정도는 유럽의 선진국과 일본 등 10여 개국에서 각각 수입하고 있고, 우리나라도 10번째의 수입국이며 세계적 소비수요는 계속 증가되고 있다. 우리나라는 1968년의 313,501ha의 재배에서 계속 감소하여 현재는 75,242ha에서 132,674톤이 생산되고 1,261천톤이 수입되었으며, 전체 자급률은 수요량 1,333천톤의 8.6%, 식용 및 기타는 수요량 387천톤의 29.5%에 불과하다. 콩, 특히 식용콩의 증산에 의한 자급율 향상은 경지정리 및 주산단지 조성을 통한 생력기계화 재배를 전제로 첫째, 밭의 작부체계 개선 둘째, 논의 밭 전환재배 셋째, 북한의 동해안 지대의 밭을 장기임대하여 재배하고 그 대가를 쌀 지원으로 하는 것이며 넷째는 인접국에서 밭을 매입 또는 장기 임대하여 생산 공급하는 방법 등을 생각할 수 있을 것이다.

This study was carried out to investigate the effects of solid mass flow rate, mean particle diameter and mesh number of screen packing material on minimum carrying velocity, which was defined as the superficial gas velocity of the upper limit of chocking phenomenon. Vertical pneumatic conveying was studied in a 4.6cm I.D. pipe, 180cm in length. Experiments were performed in both the empty and the screen-packed pipe. It was also examined the effect of superficial gas velocity, solid masss flow, mean particle diameter, and mesh number of packing material on pressure drop. Minimum carrying velocity in screen packed-pipe was lower than that in an empty pipe, besides minimum carrying velocity was decreased with increase in mesh number of screen packing material. The pressure drop in vertical packed-pipe was increased with increase in superficial gas velocity, mean particle diameter, and mesh number of screen packing material.

This study was carried out to investigate the effect of the control action, recycle ratio and the position(top, middle and bottom) of set temperature and controlled temperature within the reactor on temperature control in adiabatic ebullated recycle reactor when the disturbance was occured. Estimation of th solution were performed numerically using the finite difference method. It was assumed that heat of reaction and the physical properties(density, heat capasity and viscosity…. etc) of the flowing fluid are not nearly varied within the reactor. It was shown that the response time was shorter at higher recycle ration and the PI-control for middle point temperature of the reactor as controlled temperature was available.

This study was analyzed the validity and the reliability of evaluation norm. which was used in choosing and grading events of the General Motor Ability Test. The General Motor Ability Test has been done for applicants for entrance to the department of physical education, college of education, Pusan National University. The subjects of this study were 433 applicants(men :387, women :46) for three years. They were tested in seven events : 1) 100m Dash, 2) 1500m Run(man), 800m Run (woman), 3) Throwing Hand-Ball, 4) Broad Jump, 5) Chinning(man), Flexed-Arm Hang(woman), 6) Zig-Zag Run, 7) Trunk Flexion. The results could be summerized as follows ; 1. In 100m Dash, 1500m Run, and Throwing Hand-Ball, man's average records were shown normal distribution which was inclined toward low ll grade. Therefore, the interval size of those three events must be regulated to lower. 2. Average records of Broad Jump in man were distributed into high (1) grade. So, the interval size must be adjusted to higher. 3. In Chinning, Zig-Zag Run, ad Trunk Flexion, man's average records were shawn normal distribution, and the interval size was similar to present records. 4. For woman, it was impossible to analyze correctly in all seven events because of the small number of subjects. So, it was for the sake of the reference. 5. The record of applicants for three years were operated to the variable quantity analysis. And the restults were these ; 100m Dash was F=3.0865(p<0.05), Chinning F=3.9309(p<0.05), Broad Jump F=14.7338(p<0.001), Throwing Hand-Ball F=4.9716(p<0.01), and Zig-Zag Run F=6.8297(p<0.001). Then, it was shown statistical meaningful difference in three groups. 6. In investigating the validity in choosing seven events, it was concluded that the events have been chosen reasonably. Because all events except for 100m Dash, and Zig-Zag Run in man were independent. From the analysis of the General Motor Ability Test, we could realized the necessity of regulating the standard and the interval size in several events. Then, we proposed the new evaluation norm which was suitable to present situation.

박영홍,박기호,정우영 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.5

Purpose: The aim of this study was to investigate the mutations of HBV pre-S/S gene in HBV-associated nephropathy patients and to compare the patterns of mutations between child and adult patient, which may suggest the relationship of HBV with these diseases. Method: Seventeen fresh frozen or paraffin-embedded renal tissue samples were obtained from child or adult patients with HBsAg-positive and nephropathy. HBV pre-S/S regions were amplified with PCR and subjected to direct sequencing. Mutations were analyzed at pre-S1, pre-S2 and S gene regions and the difference of pattern was evaluated between adult and child. Results: Seventeen PCR products were direct-sequenced, of which twelve(70.6%) had the mutations at pre-S1 region. Point mutations were detected from all of 12 cases(100.0%) and resulted in amino acid substitutions as Q8OP(CAG->CCG) and L112I(CTA→ATA). Deletion mutations were detected in 2 patients(16.7%) of which one had 27 bp(3149-3175) deletion and the other 2 deletions including l5 bp(2847-2861) and 60 bp(3143-3202) deletions. The mutations at pre-S2 region were detected in 11 cases(64.7%) of which 10(90.9%) had point mutations. Amino acid substitution of T37I due to the point mutation from ACT to ATT was found in 4 cases. Deletion mutations were detected in 3 cases(27.3%) of which one had 66 bp(3203-3213,1-55) deletion which was continuous with the pre-S1 deletion. The other two had 48 bp(nt8-55) and 60 bp(nt3208-3213, 1-54) deletions, respectively. The mutations at S gene were found from all of 17 cases and are exclusively the point mutations but not the deletion mutation. At 'a' determinant(aa124-147), three amino acid substitutions including Ⅰ126N, T131A and G145R were detected. Most of mutations with high frequency and/or amino acid substitution were detected from children, including at Q8OP at pre-S1, T37l at pre-S2 and T131A at S gene. Conclusion: We could find the various mutations including point mutations and deletion mutations at HBV pre-S/S gene in kidney tissue from patients with HBV-associated nephropathy. The comparison of the mutation between the child and adult patients showed the significant difference of mutation pattern.

Asbestosis is the disease of pulmonary fibrosis caused by the inhaled asbestos fibers, and could be diagnosed clinically, in the case of exposure history to asbestos is proved, by clinical symptoms of dyspnea or dry cough, physical examonation findings, and the radiographic features. But many othder inorganic dusts would show similar findings in the chest radiogram and sometimes the exposure history is obscure, so for the exact diagnosis of asbestosis lung biopsy is needed. In Korea, there have been some reports of survey in the workplace where asbestos is handled or of asbestos related diseases. This is a case report of asbestosis with accompanying pleural plaques, who had the occupational exposure to asbestos for 30 years and the consistent clinical, radiographic and pathological findings in the lung tissue obtained by the videoscope assisted thoracoscopic biopsy(VATS).
