유능수 江原大學校 産業技術硏究所 1994 産業技術硏究 Vol.14 No.-

Up to the present the study on the performance prediction of HAWT was perfomed mainly by assuming the axial flow. So in this paper we aimed at the fully non-axial flow of HAWT. For this purpose, we defined the wind turbine pitch angle in addition to the yaw angle to specify the arbitrary wind direction. And we adopted the Glauert method as the basic analysis method then modified this method suitably for our goal. By comparing the computational results obtained by this modified new Glaurert method with the experimental results, it was proved that our method was a very efficient method.

The purpose of this study is to develop a method for predicting the aerodynamic performance of the subsonic airfoils in the 2-dimensional, steady and viscous flow. For this study, the airfoil geometry is specified by adopting the longest chord line system and by considering local surface curvature. In case of the inviscid-incompressible flow, the analysis is accomplished by the linearly varying strength vortex panel method and the Karman-Tsien correction law is applied for the inviscid-compressible flow analysis. The Goradia's integral method and the Truckenbrodt integral method are adopted for the boundary layer analysis of the laminar flow and the turbulent flow respectively. Viscous and inviscid solutions are converged by the Lockheed iterative calculating method using the equivalent airfoil geometry. And the analysis of the seperated flow is performed using the Dvorak and Maskew's method as the basic method. The wake effect is also considered and its geometry expressed by the formula of Summey & Smith when no seperation occurs. A computational efficiency is verified by the comparison of the computational results with experimental data and by the shorter execution time.

NACA 0015 익형에 대한 Gurney 플랩의 영향

유능수,이장호 강원대학교 산업기술연구소 2000 産業技術硏究 Vol.20 No.B

A numerical investigation was performed to determine the effect of the Gurney flap on NACA 0015 airfoil. A Navier-Stokes code. FLUENT, was used to calculate the flow field about the airfoil. The fully-turbulent results were obtained using the standard κ-ε two-equation turbulence model. The numerical solutions showed the Gurney flap increased both lift and drag. These results suggested that the Gurney flap served to increase the effective camber of the airfoil. Gurney flap provided a significant increase in lift-to-drag ratio relatively at low angle of attack and for high lift coefficient. It turned out that 0.75% chord size of flap was best. The numerical results exhibited detailed flow structures at the trailing edge and provided a possible explanation for the increased aerodynamic performance.

There are various item and object that used for the quality of water data but little have that used statistics for appropriately treatment. In these days, the statistics adjustment for water quality data will be understand for the subject of survey. In this paper, the authers, appliated the statistical theorem for the quality of water data of three river waters. 1. Non-exceedance probability 75% of three river waters. ─────────────────────────────────── River A River B River C River ─────────────────────────────────── Distribution BOD COD BOD COD BOD COD ─────────────────────────────────── normal Distribution 18.5 27.3 81.4 104.0 207.0 143.0 log-normal Distribution 20.0 32.0 80.5 107.0 210.0 150.0 ─────────────────────────────────── 2. The water quality data is more appropriateness than other distribution in the logarithmic normal distribution. 3. The correlation of BOD and COD in three river waters are : ─────────────────────────────────── River Correlation Correlation Coefficient ─────────────────────────────────── A-River BOD=0.249×COD+9.081 r=0.49 B-River BOD=0.825×COD-5.832 r=0.987 C-River BOD=1.125×COD+33.90 r=0.968 ───────────────────────────────────

레바논 현대 여성문학의 발전과정 연구

This thesis aims at studying the development process of the feminism literature in modern Lebanon. This is supposed to be a basic and necessary research for furthering more studies on related fields. When it comes to the start of modern feminism literature in Lebanon, its first direct motive is attributed to Arab Nahdah(Renaissance) movement which arised led by Egypt and Lebanon late 19th century, and which comprised issue of Arab women emancipation in the list of matters hotly discussed. Of other important elements contributing to earlier development of modern feminism literature in Lebanon, are activities of women's organizations established in Lebanon and Syria, and troika of Lebanese feminism in the first stage, which are literary associations, literary salons and journals led by Lebanese women. Furthermore, during period from late 19th to the first half of 20th century Lebanese women writers started representing their earliest awareness of feminism by using poetry, novel, short story and treatise. But most of their literary works involved but a few limited subjects such as enlightenment of women, support for women's rights in Arab traditional society. On the while, women writers in Lebanon during the second half of 20th century made challenges toward emancipation of women from deep-rooted patriarchism, and search for themselves. The representatives figures of these tendencies were Layl? Balabakk?, Emily Nasr Allah, Gh?dah al-Samm?n, Layl? Usayr?n and Han?n al-Shaykh. They showed with their own distinctive styles new images of Arab women, such as some heroines who ask about themselves, struggling to get freedom, and others who commit themselves to Arab nationalism. Besides, tragedy of Lebanese civil war(1975-1989) formed an element of modern women literature in Lebanon, for some women writers adopted the civil war as background or theme of their works. They dealt with various subjects concerning Lebanese war, such as overcoming violence and injustice with love, valuing nationalism in the midst of war, women's agony resulting from closed situations in the time of war.

'持身'의 心理學的 意味

이상에서 율곡이 말한 지신이나 구욕구사의 이론을 Paul이나 Allport의 현대심리학적인 이론과 관계시켜가면서 고찰하였다. 우리는 여기서 율곡이 강조한 행동적 측면이나 심리적측면이 결코 가공적인 사변에서 도출한 것이 아니라 구체적인 관찰을 바탕으로 한 성격형성 이론임을 알 수 있다. 율곡은 인간을 전체적이고 기본적인 입장에서 이해하려고 하였던 것 같다. 치종여일, 언행일치, 군자불기 등의 말은 이 전체성과 관계되는 말들이다. 상설이나 성겨과 같은 심리학적 영역은 문화적 역사적인 배경의 파악없이는 심층적 파악이 어렵다. 그렇게 볼 때 율곡의 이 이론은 시사적인 면이 크다는 것을 알 수 있다. 어떻든 율곡의 이런 이론에서 심리학의 대립적인 관계에 있다고 볼 수 있는 정신분석적인 경향과 행동주의적인 경향을 모두 흡수하고 통합하는 또 하나의 발전적 모델을 암시받을 수도 있을 것같다.

알-샵비 詩의 주제 연구

김능우 한국아랍어아랍문학회 2000 아랍어와 아랍문학 Vol.4 No.1

This paper aims at studying themes presented in Tunisian great poet of romanticism al-Sha­bbi's poems. As the result it follows that the themes are classified into two groups, the one related to al-Sha-bbi's personal life and the other composed from social motives. The first group includes such themes as the poet's despair, feeling of sorrow and vanity of life, which on the whole are derived from his tragic life, exposing his pessimistic vision of life. While it includes themes showing al-Sha­bbi's cheerful view of life, which are represented by the pleasant memory of his childhood, his affection for nature and the glorification of poetry. The second group includes themes of social revolution, which indicate al-Sha­bbi as an intellectual in agony, worried about the fate of his people suffering from the wretched life caused by the French colonialism. On this al-Sha­bbi tries to inspire the will to live into his people's hearts. In conclusion it is worth while saying that al-Sha­bbi through his keen sensibility has clearly displayed the discord in his mind between the despair of tragic life and the attachment to life.
