黃圭東 忠州大學校 1987 한국교통대학교 논문집 Vol.21 No.-

Numerical optimization is a useful tool for obtaining reasonable solutions to the engineering design problems. In this paper,numerical optimization program for microcomputer was developed using modified feasible direction method. The results obtained by the modified feasible direction method are compared with those by the feasible direction method. Modified method converges rapidly to the optimum value without zigzaging behavior, while feasible direction method has a tendency of zigaging between constraint boundaries.

機械設計를 위한 數値最適化 技法의 適用

黃圭東 忠州大學校 1988 한국교통대학교 논문집 Vol.22 No.-

Application of the Numerical Optimization Techniques to engineering design problems is useful for obtaining reasonable design variables. In this paper, concentration is on the development of an algorithm for constrained optimization problems using Robust Feasible Direction Method to find search direction and Exterior Penalty Function Method as one-dimensional search. Robust Feasible Direction Method showed a good convergence when the nonlinear constraint function was linearized by the first-order. Taylor series expansion. The introduction of Penalty Function Method enabled the optimization process to continue even if the design variables were in the infeasible region.

The present study was made based on the zero extension line theory and the seismic coefficient method to determine the seismic bearing capacity of shallow foundation. The zero extension line theory, which was proposed by Roscoe et al., presumes the coincidence between the loci of failure and the zero extension lines in soil mass. In order to compute the seismic bearing capacity of shallow foundation with smooth base mobilized by an earthquake, it was assumed that subsoils beneath the foundation are dense and cohesionless sandy soils, there are no changes in soil parameters during earthquake, and only horizontal earthquake intensity is considered. The presented theories were successfully compared with the conventional bearing capacity theories. And the effects of embedment depth of footing, earthquake intensity, dilation angle and internal friction angle of soil, on the bearing capacity factors were analysed. Finally a simplified formula for bearing capacity factor of N?? in earthquake was also provided.

Induction motor drive with PWM inverter control has been developed for Korean High Speed Railways. To improve traction performance, the anti-slip control(ASC) to recover adhesion must be considered. This paper describes a novel hybrid anti-slip control method for the induction motor drive. By introducing the vector control for drive system, quick response of the motor torque can be achieved when wheels are going to slip. A hybrid control scheme by mixing two conventional control methods (slip velocity feedback control and slip detection pattern control) for wheel slip and re-adhesion is proposed. This control method is simulated by motor drive, train load, and friction-creep models. The train running simulation results based on induction motor vector control with PWM inverter show that good re-adhesion characteristics are obtained.

Robert Lowell硏究 : "The Quaker Graveyard in Nantucket"을 中心으로

黃東奎 서울대학교 교양과정부 1973 論文集 Vol.5 No.-

1950년대에 미국시가 커다란 변모를 이룩한 것은 이미 잘 알려져 있는 사실이다. 1960년대는 초기의 활력을 잃고 너무 형식에 얽매이고 Academism화한 Eliot과 신비평가들의 시가 줄어들고 Robert Lowell, Charles Olson 그리고 Allen Ginsburg의 시가 점차 미국시의 주류를 형성한 기간이었다고 볼 수 있다. 그것은 또한 극도로 신고전주의화한 시에 대한 인간성 회복운동이었다고 볼 수도 있다. 1960년대의 미국사회는 다이내믹한 사회로 불려진다. John F.Kennedy가 대표하는 Liberalism이 표면에 나서기 시작했고 민권운동과 그 반발, 월남전 참전과 그 좌절등으로 미국의 눈이 외부뿐 아니라 내부도 살피기 시작한 것이다. 이 기간 동안 미국詩는 대체로 Olson을 중심으로 한 Black Mountain계의 새로운 호흡 및 개인의 감성을 중시하는 파와 Ginsburg를 중심으로 한 Best계의 생활의 실태를 파헤치는 파로 나눌 수 있으며 이 두 파 공통의 특징은 Eliot 및 신비평가들이 imge를 중시했던데 반해 rhythm을 중시하고 잇는 점이라고 할 수 있다. Rhythm 중시 면에서는 공통점을 가지지만 Lowell은 이 두 파의 어느 편에도 둘 수 없는 시인이다. 그렇다고 Richard Wilbur나 Howard Nemerov 등과 함께 전통적인 시인 그룹으로 묶울 수도 없다. 1963년에 자살한 Sylvia Plath등과 함께 Poetry of Confession(고백시) 그룹으로 분류되기도 하지만, Lowell에게는 개인적인 고백 이외의 요소들, 예컨대 반군사상, 그리고 사회가 지닌 모순 허위등을 고양된 rhythm으로 질타하는 힘이 있으며, 이것이 그를 다른 “고백시인”들로부터 구별시켜 준다. 한 시인의 생애를 시 이해에 앞서 내세우는 일은 별로 바람직한 일은 아니지만. Lowell의 생애가 (아직 끝난 것도 아니지만) 너무도 Eliot의 것과 대조적이라는 사실은 그 나름대로 하나의 의미를 지니고 있다고 보지 않을 수 없다. Lowell은 자기 가문의 전통대로 Havard 대학에 입학했으나 스스로 그곳을 떠나 Kenyon College로 갔고, 2차대전중에는 순응주의를 버리고 감옥에 가기도 했으며, 자기를 성장시킨 합리주의적인 개신교(Eliot의 Anglican Chuich도 여기에 포함된다)를 버리고 Catholic교도로 개종했다. 물론 그의 Catholicism을 표면 그대로 받아들여서는 안된다. 후에 자세히 설명되겠지만 그의 개종 자체는 권위에 대한 반항이었다고 보는 편이 타당하다. 이것은 결국에 가서 권위에 몸을 맡긴 Eliot의 Anglican Church로의 귀의와 반대편에 서는 입장이다. 그리고 Lowell의 시는 Eliot의 객관상관물론(The theory of Objective Correlative)적 시론에서 얼마나 거리가 먼 것들인가? Lowell의 시는 시인이 직접 개입 commit)된 시인 것이다. 하여간 Lowell의 시가 지닌 형태는 전통적인 면이 많지만 이 전통은 그러나 Eliot이 안고 있는 영국의 “court poetry"전통과는 다르다. Milton, Blake에 이어 미국의 Whitman에 넘겨진 ”ceremonial style" 가까운 것이다. Lowell과 Eliot과의 거리는 Lowell과 Olson이나 Ginsburg와의 거리보다 결코 가깝다고는 할 수 없을 것이다. Lowell의 두 번째 시집 Lord Weary's Castle(1946)의 출간은 여러가지 의미를 갖고 있다. 우선 첫째로 Lowell이 자신의 호흡을 확실히 획득하기 시작한 시집이라는 점이 있고, 두 번째로는 당시에 거의 절대적인 권위를 지니고 있었던 신비평의 규범인 “symmetry, intellect, irony and wit”를 핵심으로 지니지 않은 시를 가지고 최초로 널리 감동을 주기 시작한 시집이라고 할 수 있다. Donald Hall은 Lord Weary's Castle의 출간을 다음과 같이 말하고 있다.

유압 밸브 - 모터 시스템에 대한 H_(∞) 제어

황규동 忠州大學校 2005 한국교통대학교 논문집 Vol.40 No.2

This study describes a hydraulic fluid property compensator under the various perating conditions. Because hydraulic fluid systems have much more excellent features than other control systems, they are used in many fields. However, the characteristics of hydraulic fluid are changed due to various operating conditions. This phenomenon is called uncertainty. Especially, bulk modulus is considered as the most dominant parameter in this study Under the wide range of temperature and pressure, bulk modulus is changed. In order to overcome the uncertainty, H_(∞) technique will be used for this study. Spectral factorization, model matching problem and controller parametrization are also applied to achieve the desired robust control action. Designed controller using the H_(∞) technique, is adopted for the hydraulic fluid valve motor system.

Objectives : This study intended to obtain the interrelationship of lead exposure indices and anemia related factors for the better health management of lead exposed workers. Methods : 502 male workers in storage battery industries as lead exposed group and 106 male office workers as contorl group were selected for this study. The examined variables wer age, work duration, smoking and alcohol crinking habit, blood zinc protoporphyin concentraion (ZPP), blood lead concentration (PbB), urinary δ-aminoevulinic acid (ALAU), hemoglobin (Hb), hematocrit (Hct), serum calcium (S-Ca), serum iron (S-Fe), total iron binding capacity (TIBC), and percentage trasferrin saturation (PTS). Results : The means of ZPP, PbB ALAU in lead exposed proup were 58.4±35.7 ㎍/㎗, 27.6±10.9 ㎍/㎗, and 1.61±2.00 mg/ℓ, respectively. These three values in lead exposed group were significantly higher than control group (P<.05). The means of Hb, Hct, S-Ca, S-Fe, TIBC, PTS in lead exposed group were 15.3±1.1 g/㎗, 47.2±4.5 %, 9.4±0.4 ㎍/㎗, 124.0±67.5 ㎍/㎗, 317.1±68.5 ㎍/㎗, and 38.7±15.2 %, respectively. Hb, Hct, S-Ca, S-Fe, and TIBC in lead exposed group were significantly lower than contrl group (P<.05). PTS was no significant difference in lead exposed group and control group (P> .05). Hct, S-Ca, S-Fe, PTS were significant positive correlation with Hb and ZPP, corrected PbB, AlAU were significant negaitive correlation with Hb in lead exposed group (P< .05). On multiple regression using ZPP as a dependent variable and PbB, S-Ca and S-Fe as independent variables after adjustment for possible confounder such as age, smoking and drinking habit, Pbb, S-Ca, S-Fe and age contributed to ZPP. Conclusions : As the result of this study, it was suggested that inclusion of S-Ca, S-Fe, PTS measurement as a anemia screening test for lead workers was highly recommended for the effective prevention and early diagnosis of anemia.
