YOUNG TABLEAUX, CANONICAL BASES, AND THE GINDIKIN-KARPELEVICH FORMULA

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.

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.

李揆丸,李松,黃圭鎬,金周豪 서울市立大學校 1994 論文集 Vol.28 No.-

In recent years, the projects dealing with the marine clay have raising tendency. For example, the dredged clay can be used directly as the reclamation fill material. In this case, it is important to understand the consolidation characteristics for settlement analysis. Using conventional testing procedure, the determination of the consolidation characteris tics of cohesive soils requires consolidation time. the constant rate of strain consolidation test has been proposed as a method to reduce consolidation test time. The information used to the characteristics of settlement has been obtained using a standard oedometer test, but standard oedometer test may not be applicable to very soft soils with high water content because of limations both in theory and in testing techniques. A new constant rate of strain consolidation testing technique for very soft soils with water content of 200 to 500 % is proposed as an alternative of conventioinal oedometer test. This paper presents several benifts on the constant rate of strain consolidation test. To find the consolidation characteristics of the dredged soft clay constant-rate-of-strain consolidation testing method is used In this paper constant rate of strain consolidation test are compared with standard oedometer test for applicablity of constant rate of strain consolidation test It is concluded that the consolidation constants of very soft clays can be accurately determined from the constant rate of strain tests,also is suitable test of derdged clays as this test is applicable to regimes of the low stress level and high stress level

한국 프로 골퍼와 호주 아마추어 골퍼의 시합 중 심리상태 비교

이규환,박유현 한국스포츠심리학회 2003 한국스포츠심리학회지 Vol.14 No.4

본 연구는 한국 KPGA 프로 골퍼와 호주 아마추어 골퍼들의 수행능력에 따른 시합 중 심리적 구성 요인들을 알아내어 이를 중심으로 포괄적 심리기술 훈련 프로그램 제안이 아닌, 프로와 아마추어, 그리고 그들의 경기력에 따른 보다 체계적이고 효율적인 골프 심리기술훈련 프로그램 개발을 제안 하고자 하는데 있다. 47명(남자 47명)의 한국 투어 프로 골퍼들과 191명(남자: 153명, 여자 38명) 호주 아마추어 골퍼들이 이 연구에 참여 하였다. 골프심리검사지(GPQ: Golf Psychology, Questionnaire)가 Lydia에 의해 개발되어 본 연구에 사용되었고, 2명의 스포츠 심리학 전문가, 1명의 국어학 박사과정 대학원생, 2명의 KPGA 프로 골퍼가 GPQ의 한글번역 과정에 참여하였다. 총 20문항으로 구성되어져 있고, 5점 리커트 척도 방식을 채택하였다. 요인분석 및 내적 일관성 (internal consistency)에 의해 타당도와 신뢰도가 검증되었다. 경기력(프로골퍼 : 랭킹, 아마추어골퍼 : 핸디캡)과 심리상태와의 상관관계 분석을 실시한 결과, 일반적으로, 상위랭킹의 국내 프로 골퍼들과 핸디캡이 낮은(경기력이 높은) 호주 아마추어 골퍼들이 많은 문항에서 심리적으로 강점을 나타냈다. 프로 골퍼들의 가장 높은 상관관계는 프리샷 루틴(r=-.603)의 사용정도 이었다. 즉, 랭킹이 높을수록 프리샷 루틴을 더욱 일정하게 지키려는 경향이 있었다(아마추어: r=-.469). 아마추어 골퍼들의 가장 의미 있는 결과는 첫 티샷 이전의 긴장상태(r=.558)이었다. 즉, 핸디캡이 높을수록(경기력이 낮을수록) 첫 티샷 때 많이 긴장하는 것으로 나타났다. 일반적으로 경기력이 높은 프로와 아마추어 모두 골프 시합 중 심리적 준비상태의 중요성을 인식하고 있지만, 프로 골퍼들에게 중요한 결과가 반듯이 아마추어들에게 적용되는 것은 아니고 아마추어 골퍼들에게 중요한 상관관계가 프로 골퍼들에게는 의미 없이 나타나기도 했다. 심리기술을 사용하는 것은 골퍼의 최적 수행에 도움을 준다. 따라서 스포츠 심리학자들은 골퍼의 수행능력에 따라 보다 체계적이고 효과적인 골프 심리기술 훈련 프로그램을 개발해야 하겠다. The purpose of this study was to compare the psychological readiness of Korea PGA Tour golfers with Australian Amateur golfers. 47 Korea professionals (47 male) and 191 Australian amateurs (153 male ;38 female) participated in this study. The Golf Psychology Questionnaire (GPQ) was developed by Lydia (1999) and based on questions from the MTE-1 (Partington & Orlick). It was translated into Korean by 2 Ph.D. (sport psychologist) and I graduate student (Korean Language) and 2 KPGA players. It was 20-item questionnaire and responses were indicated on a 5-point Likert scale (1=strongly disagree, 5=strongly agree). Principal Component Analysis supported the content validity and Cronbach's alpha revealed the internal consistency of the GPQ. In general, it was found that higher ranking Korea professionals and more advanced Australian amateurs rated higher on many questionnaire items reflecting greater strength of mental skill factors. The highest correlation of Korea PGA Tour golfers was the extent of reported usage of 'pre-shot routine'(r=-.603) while the highest correlation of Australian amateur golfers was the ratings for 'feeling anxious' before hitting off the first tee (r=.558). Even though both professionals and amateurs realized the importance of the psychological readiness in golf performance, some significant correlations for professional golfers were not as much as significant to amateurs or several significant results for amateur golfers were almost meaningless to professionals. The utilization of psychological skills has been shown to increase the golfer's performance level. Therefore, with the aid of a sport psychologist, golfers should develop psychological skills according to different levels and improve their golf game.

The purpose of this study was to observe and analyze the recreational activities of the college students in terms of finding some possible ways to lead them into a sound, positive living mode. For this purpose, a total of 300 college students - 150 male and 150 female evenly- were given the questionnaire on which how to spend their leisure time was asked. The result is as follows : 1) According to the feedback, most collegian have the leisure times from 3 to 5 hours a day. 2) In a time-free from school classes, the 10% of them is engaged in some physical activities, which consists of the 3% for soccer, the 1.7% for pingpong and tennis, the 1.3% for basketball, and the 1% baseball. 3) The 14.3 precent of the total numbers spends their leisure times after all the classes are over in some physical activities. The 3.7% of the given percentage are playing tennis, the 2.7% playing soccer, the 2.3% going to health club, and the 2% pingpong. 4) A 17% of the percentage consists of those who are devoted to some physical activities for the recreation of the holidays and the weekends. Of the 17%, a 3.7% climbs mountain, a 3.3% is engaged in playing tennis, 2% in pingpong and health club, 1.7% in rope-skipping, and 1.7% in swimming. 5) Their attitudes toward the sport game in the leisure time were very serious to a degree of fighting to the last. 6) Most students tend to avoid having their physical activities early in the morning : therefore, it is necessary to encourage them to do physical activities in the morning. 7) Most of those who don't make use of their leisure time for doing something physical tend to spend their time in their home watching some sport game on T. V. rather than directly going to playing ground to see it because a number of broadcasting T. V. stations hookup a number of sport games.

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.

이영수,정세환,이규식 대한구강보건학회 2003 大韓口腔保健學會誌 Vol.27 No.4

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.

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.
