Cray T3E 상에서의 선형 시스템 해를 위한 COIS 프로그램

우제학 대진대학교 정보통신연구소 1998 정보통신 논문집 Vol.1 No.-

Recently, challenges to larger and more complex problems have been pursued in several scientific as well as commercial fields. The progrmamers in these fields have turned to high-performance parallel computing in order to find solutions for their problems in ever shorter times, However, parallel programming is a very difficult job because it needs a different concept with traditional sequential programming, In this paper, we present parallel programming using an implicit parallel language, COIS. We especially focus in solutions for linear systems, because they are usually generated in process of solving partial differential equation in scientfic computation. We consider three methods solving linear systems, and present COIS progrmas based on the algotithms.

Objectives:This study was to identify weight & metabolic changes in first-episode psychotic patients with antipsychotics use and investigate the differences of weight & metabolic changes between first-episode psychotic patients and controls with antipsychotics use. Method:In this retrospective study, twenty eight first-episode psychotic patients and twenty eight controls with schizophrenia, schizoaffective or bipolar disorder defined by DSM-IV criteria were included. Information about demographic and clinical characteristics of the subjects was gathered from the medical records. Also body weight, sBP, dBP, fasting glucose, lipid profile and WBC count were evaluated before and after antipsychotics use. Rogistic regression was conducted to assess factors associated with weight gain. Results:First-episode psychotic patients showed more weight and BMI changes than controls after antipsychotics use, and these changes continue over 12 months. On the other hand, there were no significant factors associated with weight gain. Conclusion:The results of present study suggest that antispychotics is one of the major causes inducing weight gain of psychotic patients and antipsychotics-induced weight gain is more vulnerable to drug-naive first-episode psychotic patients.

공진 기초를 이용한 아스팔트 콘크리트의 동적 전단계수 추정에 관한 연구

우제윤,김수일,이형인 연세대학교 산업기술연구소 1985 논문집 Vol.17 No.2

In this study, a resonant footing technique to estimate the dynamic shear modulus of asphalt concrete using the torsional vibration test is developed. From this study an empirical formula is proposed to estimate the dynamic shear modulus of asphalt concrete. The numerical results are compared with the values estimated from the measurement of primary wave velocities. The oscillator made for this study has thin circular bars which are considered as springs. Heavy upper part of the oscillator is connected to lower aluminum plate by means of springs. The oscillator is designed so that torsional vibration of aluminum plate is caused by magnetic force and footing-asphalt concrete system also vibrates together with aluminum plate. From the experimental result, the maximum difference of the dynamic shear modulus from the resonant footing test and primary wave velosity detection shows 3% deviation when the Poisson`s ratio is assumed to be 0.3. The apparatus made for this study is thought to estimate the dynamic shear modulus of asphalt concrete properly. It is also found that the dynamic shear modulus is not influenced by confining pressure within the range of confining pressure applied in this study.

완두의 rbcS 유전자가 삽입된 pAC1350 vector 에 hygromycin transfere 유전자를 선별지표 (selector marker) 로 재삽입하여 p35SSU-HPH vector을 구성하고 이를 이미 antisence 유전자에 RUBISCO small subunit 유전자 발현이 억제된 식물체에 형질전환시켜 재분화를 유도하고 계속적으로 배양하여 그 종자를 채종하였다. 채종된 종자는 발아시 hygromycin이 함유된 배지에서도 16% 정도는 생장이 가능하였고, Southern 과 Northern bolt hybridization 의 결과 HPH 유전자를 핵내에 보유하고 있으며 완두의 rbcS유전자의 전사도 이루어지는 것으로 확인되었다. 이들을 생장속도에 따라 대, 중, 소로 구분하여 Southern bolt hybridization을 수행한 결과 모식물체 (parental plant)에서 보호하고 있는 4개 이상의 antisence 유전자는 0 - 4개의 band로 검출되어 생장이 좋을수록 antisence 유전자의 copy 수가 적은 것으로 확인되었다. 이들 종자의 광합성 능력은 모식물체와 정상 담배 식물체(SRI)의 중간을 나타내어 완두의 rbcS 유전자가 종자를 통하여도 전달됨을 보였고 이들 식물체의 세포내 CO₂ 농도는 400 μbar 정도로 일정하게 유지되어 삽입된 유전자에 의해 외부로부터 CO₂를 흡수하는 능력이 향상된 것으로 나타났다. RUBISO (Ribulose bisphosphate carboxylase/oxygenase) is sharply reducd in transgenic tobacco carrying and rbcS antisense(Rodermel et al., Cell 55:673-681/ 1988):expression of most if all member of the tobacoo rbcS family is reduced. To replace the tobacco rbcS gene products, plants with the tobacco antisense gene were transformed with T-DNA containing a 35S cauliflower mosaic virus promoter : pea rbcS gene and the hygromycin phosphotransferase gene. Such transgenic plants accumulated more RUBISCO small subunit protein than the parental strain and their photosynthetic activity was enhanced up to 150%. Progenies of selfed "double- transgenic" plants showed similar, though variable, patterns of hygromycin resistance and enhanced photosynthetic activity.

In this study, a data reduction method is developed to predict the dynamic shear modulus of each layer of multi-layered soil from the measured surface wave velocities. The method developed utilizes the vertical amplitude attenuation curve of surface wave in homogeneous soil. Numerical model studies show that the technique developed in this study is more accurate compared with the one-third technique widely used for the time being. The maximum error of data reduction from the technique developed in this study is found to be approximately one half of that of data reduction from the one-third technique. It is also found in this study that assumed Poisson`s ratio may by used without causing any significant error, however, unit weight of each layer should be exactly estimated in order not to cause any significant error.

선형계획법에서 사전처리 기법에 관한 연구

김우제 대진대학교 1998 大眞論叢 Vol.6 No.-

The purpose of the paper is to develop the methods for preprocessing for simplex method and interior point method in linear programming. We classified the methods for preprocessing into (1) analytic methods, (2) methods for removing implied free variables, (3) methods using pivot or elementary row operations, (4) methods for removing linearly dependent rows and columns, and (5) methods for dense columns. We noted some considerations which should be paid attention when preprocessing are applied to simplex method and interior point method. We implemented the proposed preprocessing method, and tested it with 28 large scale problems of NETLIB. We compared the results of it with those of preprocessing routines of SOPLEX, HOPDM, BPDPM and CPLEX.
