The purpose of this paper is to investigate key ethical issues and hindrances to ethical behavior faced by professionals working in Korean insurance industry. For this purpose, conducted is a survey of actuaries in a variety of positions in insurance companies and insurance related institutions. The findings also are compared to those of American studies. Actuaries' perceptions of the key ethical issues tend to be restricted to actuarial aspects such as insufficient legal authority to perform professional services in an ethical manner and failure to get adequate ethics training program. But some issues arising in marketing are considered significant similar to the U.S. As a whole, key ethical issues and challenges are not significantly different from the viewpoints of actuaries working in the life and non-life insurance business. Regarding key hindrances to ethical behavior, the 15 factors are presented such as competitive pressures, performance-based evaluation and unethical demand made by clients. These findings are generally similar to those of the U.S. studies.

This paper deals with the vibration and noise characteristics of three different kinds of pipe structures (PVC pipe, cast-iron pipe and newly developed pp pipe). In order to measure the structure born noise, an impact force generated by dropping a small ball was applied to three different kinds of pipes. It was confirmed that the structure born noise could be reduced by employing a high damping material. Also, transmission loss of a pipe was investigated for various frequency ranges by using a speaker as a sound source.

비행중에 항공기의 연료를 절약시키는 가장 중요한 요소는 항공기의 항력을 감소시키는 것으로서 본 연구에서는 연료 절약형 이음속 항공기의 개발을 위한 유도항력감소에 관한 기초적인 연구를 수행하였다. 날개의 형상에 따라 유도항력이 달라지므로 이 항력을 최소로 하는 날개끝의 형상에 대한 연구와 날개끝 와류를 제어하는 유도항력 감소장치에 대하여 이론해석 및 풍동실험을 통한 연구를 하였다. 날개끝의 형상으로는 날개 끝에 camber와 파형이 있는 새로운 crescent형 날개끝 모양에 대한 공력특성을 구하였다. 날개 끝에 장착하는 유도항력 감소장치로서 날개끝 strake, 방사형 다중슬롯에 대한 기술을 개발하였다. 여러 가지 모양의 날개끝 strake를 설계하여 직사각형 날개, 테이퍼형 날개 및 뒤젖힘 날개에 장착하여 수치해석 및 풍동실험을 통한 공력특성을 조사하였다. 날개 끝에 방사형으로 설치한 다중슬롯장치가 날개끝 와류를 제어하여 날개의 양항계수에 미치는 효과를 실험적인 방법으로 연구하였다. The most important factor in saving fuel during flight is the reduction of aerodynamic drag of the aircraft. In this study, a basic research has been carried out to reduce the induced drag for the development of fuel economical subsonic aircraft. The wing tip configuration and devices to reduce induced drag were investigated by numerical analysis and experiment. To study the aerodynamic characteristics of a wing tip shape, wind tunnel testing and numerical analysis were carried out for a newly developed crescent wing tip with camber and wavy tip shape. For the wing tip drag reduction devices such as wing tip strakes, and radial multiple slots were developed. Various shapes of wing tip strakes were designed and wind tunnel tests were conducted to investigate the aerodynamic characteristics of wing tip strakes for a rectangular wing, tapered and 35 degree swept back wing. An experimental study was performed for effect of the multiple slots which were formed at the wing tip radially on the coefficient of lift and drag of a wing by reducing the trailing vortex effect.

Taurine 첨가에 따른 국수의 품질 특성 변화

고봉경 계명대학교 생활과학연구소 2001 科學論集 Vol.27 No.-

Taurine was added to wheat flour noodles to investigate the effects on properties of dried and cooked noodles. Addition of taurine up to 3% of flour did not affect mixing properties of dough. Taurine improved the aftertaste and softness of noodle, which resulted in increase of preference of noodles. However brightness of dried and cooked noodles were not improved with taurine addition. Cooking loss and protein loss were decreased and carbohydrate and turbidity of broth were increased with addition of taurine.

In electrical impedance tomography (EIT). the resistivity(impedance) distribution of the unknown object is estimated from boundary voltages induced by different current patterns with various reconstruction algorithms. In this paper. we propose a dynamic EIT reconstruction algorithm based on the extended Kalman filter(EKF). The reconstruction problem is formulated as dynamic equation which consists of the state equation and the observation equation and the unknown state is estimated recursively with the aid of the EKF. Computer simulations for the 16-channel synthetic data are provided to illustrate the reconstruction performance of the proposed algorithm.

To study allelopathic of naturally occurring substances emitted from Pinus koraiensis, the effects of water extracts and volatile substances of the tree on callus induction and bacterial culture were examined. The induction and growth of callus were inversely proportional to the concentration of the extract and of the essential oils supplemented to Murashige and Skoog's media. However, low concentration(5μl/l) of essential oil promoted callus growth. In germiculture of several bacteria, the extracts of Pinus koraiensis markedly showed the inhibitory effects on bacterial growth. It was, therefore, confirmed that the chemical substances of Pinus koraiensis tree clearly showed the biological toxic activity at high concentrations.

Grassmann 다양체가 특성류에 미치는 영향은 매우 크며 Stiefel 다양체는 Grassmann 다양체를 정의하기 위한 전초적인 다양체이다. 따라서 Stiefel 다양체의 위상적인 측면에서의 연구는 대수적 위상수학에 있어서 매우 중대하다. Yasui[5]는 복소수적 상 Stiefel 다양체의 Homotopy 형을 연구하였다. 본 논문에서는 Yasui의 연구에서 암시를 얻어 실 사영 Stiefel 다양체 RV_(4n,k) 와 4원수적 상 Stiefel 다양체 HV_(4n,k)의 Cohomology 구조들을 몇가지 밝혔다. Ruiz[4] studied the cohomology structures of complex projective Stiefel manifolds and verifies some properties on them, and Yasui[5] studied the homotopy type of the complex quotient Stiefel manifolds of V_(2n,k). In this paper, we have verified some remarks on the real projective Stiefel manifolds and quaternionic quotient Stiefel manifolds of V_(4n,k) which are motivated by the results in Ruiz[4] and Yasui[5].

According to the improvement of PC performance, it is expected that calorific value, which causes PC to malfunction, is increased. Therefore, the development of new cooling system is recently required. As the method to solve this problem, we developed loop type heat pipe. The heat pipe, which is a sealed box attached wicks, has a high performance on heat transfer, using a huge laten heat which is a generated during a phase change. Thermosyphon is a simple sealed tube in which a little working fluid is filled as the state of a static liquid pool. The advantage of heat pipe and thermosyphon is like that these are a small size, light weight, simple shape and long life. In addition, these have a good performance on a heat response and a coefficient of heat transfer, a wide rane of applicable temperature and no a supply of power from the outside. On the other hand, these have defects like that these have a large flow resistance and thermal resistance, and a heat transfer is restrained by the working limit. In this study, it is confirmed that loop type heat pipe reduces a flow resistance and thermal resistance and has a good performance on a cooling effect.
