Lee, Kyu-Hwan,Salisbury, Ben Korean Mathematical Society 2014 대한수학회지 Vol.51 No.2

A combinatorial description of the crystal $\mathcal{B}({\infty})$ for finite-dimensional simple Lie algebras in terms of certain Young tableaux was developed by J. Hong and H. Lee. We establish an explicit bijection between these Young tableaux and canonical bases indexed by Lusztig's parametrization, and obtain a combinatorial rule for expressing the Gindikin-Karpelevich formula as a sum over the set of Young tableaux.

제약업종 부산물 및 화장품 제조업 폐수처리오니의 고추 비해에 미치는 영향

임동규,이상범,권순익,이승환,소규호,성기석,고문환 한국환경농학회 2004 한국환경농학회지 Vol.23 No.4

본 연구는 퇴비의 원료로 지정된 제약업종 부산물(공정오니) 및 화장품 제조업 폐수처리오니를 시용한 후 고추를 재배하면서 시용한 오니에 의한 작물의 비료의 피해를 밝히기 위해 포장에서 작물의 생육과 수량(적과, 청과), 시기별로 토양 및 식물체 중 중금속 함량 등을 조사하였다. 토양 중 유기물 및 질소성분은 시험재료의 성분함량이 높은 처리구에서 생육 초기(6월 11일)에 높았다. 토양의 중금속 성분에서 전함량의 경우 As성분은 생육 중기(7월 8일)에 함량이 급격히 높아졌다가 감소하였으며 Zn·Cu·Pb·Cd성분은 수확기에 갑자기 함량이 증가하였고, 1 N-HCI 가용함량에서 Zn·Cu·Pb·As성분은 생육 중기에 증가하였다가 감소하는 경향이었다. 고추의 생육(초장, 간경)은 초기에는 오니구(제약오니3구 제외)가 화학비료구보다 전반적으로 불량하였는데 이는 유기물 함량이 높은 미 부숙된 오니의 영향인 것으로 생각되며, 생육 후기에는 회복이 되어서 화장품 오니구를 제외하고는 서로 비슷하였다. 고추 식물체(잎, 줄기)의 질소함량에서 생육 초기 및 중기에 제약오니1과 돈분구가 높은 것은 이들 시험재료의 유기물 및 질소성분의 특성과 함량에 기인된 것으로 보이며, 식물체 중 중금속 함량에서 잎은 Zn·Pb·Ni성분이, 줄기는 Zn·Pb성분이 수확기에 급격히 높아졌으므로 이들 성분에 대해서 주의할 필요가 있다고 생각된다. 고추의 총 적과 수량은 가축분뇨 > 제약오니3 > 제약오니1 > 화학비료 > 제약오니2구 순으로 낮아졌으며, 화장품오니구는 타 처리구보다 상당히 감수하였다. 수확기 고차 청과 및 적과의 중금속 함량은 Zn과 Cu성분이 타 성분들보다 높았고, 처리별로는 청과에서 Zn 및 Ni성분은 제약오니1구가, Pb성분은 제약오니3구가 타 처리구들보다 조금 높아서 유기성 오니를 퇴비원료로 사용할 경우 오니 중의 Zn·Cu·Pb·Ni성분의 특성과 함량이 상당히 중요할 것으로 판단된다. 따라서 퇴비원료로 지정된 오니 중에서 화장품오니와 제약오니2에서 생육 후기부터 수확기에 걸쳐 질소성분의 부족 현상에 의한 생육부진과 낙엽, 어떤 원인인지 알 수 없지만 비해에 의한 수량감소 등의 원인을 앞으로 연구를 통해서 밝힐 필요가 있다고 생각된다. 본 시험의 결과는 퇴비원료로 지정하거나, 지정된 퇴비원료의 사용을 신청할 때 허가할 퇴비원료가 작물에 대해 적합한지 알아보는 방법의 일환으로 활용될 수 있을 것이다. Three sludge types from pharmaceutical byproducts and one sludge type from cosmetic waste-water sludge as raw materials of compost were used in a field based concrete pot (4 m², 2m × 2m) for investigating damage of red pepper cultivation. These sludges and pig manure (1 Mg/10a, dry basis) were incorporated into the upper of clay loam soil prior to transplanting with red pepper. Changes in concentration and properties of heavy metal for both of soil and plant were investigated 4 times during of red pepper growth. Plant height and stem diameter of red pepper in sludge treatments except to Pharmaceutical sludge 3 were poor than those of NPK treatment. This result were regarded as an effect of incompleted decomposition sludge which has a lot of organic matter concentration. Amount of total As was increased rapidly Jul. 8. in soil, total Zn·Cu·Pb·Cd were in harvest time, and 1 N-HCl extractable Zn·Cu·Pb·As were rised at middle stage and then decreased. Amounts of nitrogen in plant (leaf and stem) were high in Phamaceutical Sludge 1 and Pig Manure treatment in early and middle stage because of organic matter and nitrogen concentrations and characteristics. Amounts of Zn, Pb, and Ni in leaf and amount of Zn and Pb in stem were increased in harvest time so that we need to have a concern in detail. Total yield of red pepper was Pig Manure > Phamaceutical Sludge 3 > Phamaceutical Sludge 1 > NPK > Phamaceutical Sludge 2 and Cosmetic Sludge treatment was decreased considerably to compare to others. Amounts of Zn and Cu in green and red pepper in harvest time were higher than the other heavy metals. Finally these results can use to utilize that finding damage on crop for authorization and suitability estimation of raw material of compost.

The structure of sodium trans-bis(methyliminodiacetato) chromate(Ⅲ), C_10H_14O_8N_2CrNa, has been elucidated with two space groups P 1-; a=8.9856(6), b=13.308(1), c=6.261(1)Å, α=76.38(1), β=110.361(9), r=107.394(6)˚, V=662(2)Å^3, Z=2, μ=0.47mn^(-1), d=1.831Mg/㎥, R=0.0295 for 1901 independent reflections with F^2>2σ(F^2), and A2/n; a=13.65(5), b=6.261(1), c=16.85(6)Å, β=113.05(1)˚, V=1324(7)Å^3, Z=4, R=0.0287 for 1013 independent reflections with F^2>2σ(F^2). There are two different asymmetric half molecules in triclinic system and one asymmetric half molecule in monoclinic system. The structures of three different molecules are very similar in conformations. The four carboxyl O atoms and the two imino N atoms in each molecule produce a distorted octahedral coordination geometry around the Cr atom. The average distances of Cr-O(carboxyl) and Cr-N(imino) are 1.956 and 2.061Å respectively. Molecules are held together by ionic forces. In this paper, it has been also shown that the cell constants, Miller indices, atomic coordinates, lattice directions and reciprocal lattices of the two space groups can be mutually transformed.

이용재,고광용,원동준,길근환,이규승 한국환경농학회 2003 한국환경농학회지 Vol.22 No.3

복숭아의 생산단계에서 잔류허용 기준과 최종 소비단계에서의 잔류양상 평가자료로 활용하기 위하여 복숭아에서의 procymidone, chlorpyrifos 및 cypermethrin의 포장상태에서와 실온(20°C) 및 저온(4°C) 저장시 잔류양상을 알아보았다. Procymidone의 포장상태에서의 반감기는 표준량 3.1, 배량 3.4일로 나타났고, chlorpyrifos는 포장상태에서 포준량 7.2, 배량 5.8일로 나타났으며, cypermethrin은 표준 10.1, 배량 14.4일로 나타났다. 약제 살포 후 초기 부착량이 MRL 이하로 내려갈 때까지의 시간을 계산해 본 결과 배량으로 살포 할 경우 procymidone과 chlorpyrifos는 안전사용기준 보다 시간이 오래 걸렸지만, 표준량으로 사용할 경우 별다른 문제가 없는 것으로 나타났다. 저장기간 중의 procymidone, chlorpyrifos, cypermethrin의 반감일수는 20°C에서 4.6, 10.2, 12.9일 이며, 4°C에서는 16.1, 14.3, 13.1일로 저온에서의 반감기가 실온에서보다 더 긴 것을 알 수 있었다. 한편 세척방법에 의한 잔류농약의 제거율은 수돗물에서는 최고 procymidone 82.9%, chlorpyrifos 27.0%, cypermethrin 24.0%로 나타났고, 세제를 사용 할 경우 procymidone 88.8%, chlorpyrifos 59.0%, cypermethrin 59.4%의 제거율을 보였다. The residue patterns of procymidone, chlorpyrifos and cypermethrin in peaches were examined. The pesticides were sprayed at 15 days before harvest and then were determined the residue at 0, 1, 2, 3, 5, 7, 10 and 15 days after pesticide application and calculated their DT_(50). Also, the degradation patterns at 4℃ and 20℃ during storage period were compared. Biological half-lives of procymidone, chlorpyrifos and cypermethrin in peaches during the cultivation period were 3.1, 7.2 and 10.4 days, respectively. The biological half-life of procymidone was shorter than the others. During the storage period, half-lives of procymidone, chlorpyrifos and cypermethrin were 16.0, 14.3 and 13.1 days at 4 C and 4.6, 10.2 and 12.9 days at 20℃, resp ectively. The degradation rates of these three pesticides in storage period were slower than them in cultivation period. Removal rates were 22.2--82.9% by tap water, and 12.5∼88.8% by detergent solution.

Objectives: This study aims (1) to determine the actuarial budget of national insurance payment for some items of preventive dental service and (2) to obtain basic data to develop dental policy which is for including preventive dental service within insurance payment. Methods: Pit and Fissure Sealing (PFS), Self-plaque Control Instruction (S-PCI), and Fluoride Topical Application (FTA) were selected for some items of preventive dental service. The actuarial budget of insurance payment was calculated through multiplying followings; 1) Applicable population or number of teeth (based on population data and Korean National Oral Health Survey 2000) 2) The usual and customary fee of 2001 from three dental colleges which have preventive dental clinic or RBRVS (Resource-based relative value scale) fee which was multiplied the RBRVS developed through the research of Yonsei University and conversion factor Korean Ministry of Health and Welfare had announced at 2001 as 55.4 won 3) 70% of insurer share rate 4) The utilization rate of the items of preventive dental service presumed to be at least 5% and at the most 36% Results: Actuarial budgets of 1) PFS are 18.8 billion (usual and customary fee) and 5.7 billion (RBRVS fee) for 5% utilization rate and 135.1 billion (usual and customary fee) and 41 billion (RBRVS fee) for 36% utilization rate when limited to first molar and second molar which are firstly facing teeth of 6-14 age group; 2) FTA are 2.5 billion (usual and customary fee) and 1.5 billion (RBRVS fee) for 5% utilization rate and 18.3 billion (usual and customary fee) and 10.6 billion (RBRVS fee) for 36% utilization rate when applied only to 6-14 age group annually once; 3) S-PCI are 9.1 billion usual and customary fee) and 5.5 billion (RBRVS fee) for 5% utilization rate and 65.7 billion (usual and customary fee) and 39.8 billion (RBRVS fee) for 36% utilization rate when limited over 12 age group who could have periodontal pocket. Conclusions: The actuarial budgets of PFS, FTA, and S-PCI if they were included within insurance payment system are minimum 13 billion and maximum 219 billion. It is presumed, however, that over 1,000 billion for dental treatment and the pain and time consuming from oral &ease could be decreased when dental caries and periodontal disease were prevented effectively. As a conclusion, preventive dental service should be included to the insurance payment system to decrease budget.

이경규,윤도준,장환일 大韓神經精神醫學會 1992 신경정신의학 Vol.31 No.1

The purpose of this study was to investigate : (l) whether seasonal affective disorders (SADs) exist among affective disorders in Korea ; (2) if there were SADs in Korea, whether they would be different from other countries' reports describing SAD as having atypical depressive symptoms ; and (3) Is there any difference between winter depression and summer depression as shown in the studies from other countries ; ie. WD shows atypical depressive symptoms and SD shows typical depressive symptoms ? The 76 subjects, having had suffered relapses for at least 2 years in succession, were selected from 375 patients with affective disorder who had been admitted to the Department of Neuropsychiatry of Kyung Hee University Hospital during the 10 years, from 1 January 1980 to 31 December 1989. This study was done by reviewing their records, making a comparison between SAD with depression (n=23) and nonseasonal affective disorder (NSAD) with depression(n=25). Also, another comparison was made between SD(n= 14) and WD(n=9) in SAD. They were analyzed according to sex, age of onset, season of birth, occupation, premorbid personality. family history of psychosis, and atypical depressive symptoms-hypersomnia. hyperphagia. carbohydrate craving, and irritability. The results were as follows : 1) There indeed were patients with SAD in Korea. The prevalence of SAD in this study was 10.9%. 2) Comparison between SAD and NSAD with depression : There was a significantly higher number of patients with NSAD with depression among those with indoor occupations and in families with a history of psychosis compared with patients with SAD with depression (p<0.05). There were no significant difference between them in other factors. 3) Comparison between SD and WD in SAD : There were no significant difference between them in all factors. In conclusion, SAD exists in Korea. But, there are no significant differences in depressive symptoms between SAD and NSAD with depression, or between SD and WD as is the case in the previous studies from other countries.

이권범,박환규,홍석주,김기형 조선대학교 동력자원연구소 1996 動力資源硏究所誌 Vol.18 No.1

In this study, when CFRP lamimates are subjected to static loading by the indentation of steel ball to examine a failure mechanism of lamimates, the fracture surface of interlaminar delamination generated at interfaces is investigated by the scanning electron microscopy (SEM). When orthotropic CFRP laimates stacked with two interface are subjected to static loading, interlaminar delaminations extend from the loading side to delamination edge even at any interface, and the fracture surface fo interlaminar delamination generated at two interfaces is symmertrically formed. In the CFRP laminates, the fracture mechanism sppears mainly to be the mixed mode(modes Ⅰ+Ⅱ), and the ratio of mixed mode varies partially. After the fracture initiates at the interface near the loading side with mode Ⅰ, the mixed mode gradually developes, but the total surface at the opposite plane to the loading side fractures with the mixed mode(modes Ⅰ+Ⅱ). While transverse cracks are generated, the direction of shear stresses reverses itself ar the delaminated surface, clarified by the hackle direction of fracture surface.

이원규,안중환,박규열 韓國工作機械學會 2000 한국생산제조학회지 Vol.9 No.3

In machining screws which are important members in mono pumps or progressive cavity pumps, CNC turning center with 3 axes is usually used. This soil of screw machining requires large amount of CL data points and rotational tools are used in machining. When working out the CL data points, consideration of possible tool interference is important in order to avoid undercut. This paper describes the checking methods of tool interference that could occur in the screw machining on the CNC turning center. First of all a specific shape of a screw cross-section that could commonly be applied to all screws was chosen, and then possible tool interference associated with that shape was identified. Checking method was mathematically developed and verified. This checking method will be utilized in the CAM system developed by the authors for screw machining on the 3-axis CNC turning center.
