인간은 사고하는 존재, 그리고 언어를 사용하는 존재라는 사실은 바로 인간이 지향적 주체라는 것을 보여주는 두가지 특징적 측면이다. 즉 심성내용과 의미는 지향적 대상의 두 축이라고 할 수 있다. 그런데 데이빗슨은 자비(charity) 혹은 합리성(rationality)이라는 동일한 원리에 기초하여 내용과 의미의 통일적 이론을 모색한 철학자이다. 이 논문에서는 데이빗슨의 내용과 의미의 이론을 반(反)데카르트적 관점으로 해석함으로써 데이빗슨 철학이 갖는 비트겐슈타인적 경향을 검토한다. 즉 데이빗슨의 내용과 의미론을 비트겐슈타인적 시각에서 조명하고 둘 사이에 어떤 연속성과 차이가 있는지를 논의함으로써, 데카르트 전통의 지향성 개념을 모색하는 새로운 지향성 개념을 모색하는 것이 이 논문의 목표이다.

한국어 명사 어절의 시간 경과에 따른 처리 양상을 확인해 보기 위하여 점화어절판단과제(primed eojeol decision task)를 이용한 실험을 실시하였다. 점화어 제시 방식은 차폐점화, SOA 100ms, SOA 300ms 조건으로 하였으며, 점화어-표적어의 관계는 어절일치, 어간일치, 통제조건으로 조작하였다. 그 결과 어절일치조건과 어간일치조건에서 촉진효과가 있었으며, SOA가 증가함에 따라 어절일치조건과 어간일치조건에서의 촉진효과도 함께 증가하는 양상을 확인하였다. 점화어의 제시 방식과 점화어-표적어의 관계간의 상호작용도 유의미하였다. 이러한 결과를 바탕으로 심성어휘집에서의 어절 표상의 실재성과 어절 속성과 어간 속성이 어절 처리 과정에 관여하는 방식에 관하여 논의하였다.

In statistical process control applications, variable sample size (VSS) $\bar{X}$ chart is often used to detect the assignable cause quickly. However, it is usually assumed that only one assignable cause results in the out-of-control in the process. In this paper, we propose the algorithm to minimize the function of cost per unit time and compare the economic design and the statistical design by use of the value of cost per unit time. We consider double assignable causes to occur with compound in the process and adopt the Markov chain approach to investigate the statistical properties of VSS $\bar{X}$ chart. A procedure that can calculate the control chart's parameters is proposed by the economic design.

The coefficient of variation(CV) which is a relatively dimensionless measure of variability is widely used to describe the variation of sample data. However, the properties of CV distribution are little available and few research has been done on estimation and interpretation of CV. In this paper, we give an outline of statistical properties of coefficient of variation and design of control chart based on this statistic. Construction procedures of control chart are presented. The proposed control chart is an efficient method to monitor a process variation for short production run situation. Futhermore, we evaluated the performance of CV control chart by average run length(ARL).

Data mining technique is the exploration and analysis, by automatic or semiautomatic means, of large quantities of data in order to discover meaningful patterns and rules. This paper uses a data mining technique for the prediction of defect types in manufacturing Process. The Purpose of this Paper is to model the recognition of defect type Patterns and Prediction of each defect type before it occurs in manufacturing process. The proposed model consists of data handling, defect type analysis, and defect type prediction stages. The performance measurement shows that it is higher in prediction accuracy than logistic regression model.

Object : In this study, the effect of herbal external therapy, aromatherapy, herb medication against atopic dermatitis was investigated. Method : Atopic dermatitis grade and the effect of medication was determined using Kunz type and SCORAD index. Atopic dermatitos lesion was checked by taking pictures Result : The patient's admission SCORAD index was 74.2 but during 32 days admission treatment the patients's symptoms are getting reduced. At last when she discharged, the SCORAD index was 16.1. Conclusion : In this study, herbal external therapy, aromatherapy and herb medication were shown to treat atopic dermatitis effectively by decreasing itching, oozing, crust, dryness, lichenification. It is very possible that external therapy can offer a valuable mode of the treatment of not only atopic dermatitis but also another eczema.

Object : In this study, the effect of herb medication and acupuncture against angioneurotic edema was investigated. Method & Result : The symptoms of angioneurotic edema such as edema, redness, tenderness, itching were determined by using an arbirary definition and angioneurotic edema lesion was checked by taking pictures. These patients were treated by herb-medication and acupuncture. In the result, their symptoms were disappeared rapidly. Conclusion : This study suggests that herb-medication and acupuncture were effective treatment of angioneurotic edema. So further research is needed continuously.

This paper considers a modeling and identification for the MIMO magnetic bearing system. To obtain the nominal plant transfer functions, we have experimented on the frequency response by a closed-loop identification method because the system is unstable essentially. We suggest a method of curve-fitting for obtaining the transfer function from the frequency responses by using the system's modeling structure and two controllers which are different from each other. From the frequency response results, we found the effects of coupling by opposing controllers. And using this effects and the system's modeling structure, we could obtain the transfer functions of which have the same modularized denominators.

This paper considers a modeling for the MIMO magnetic bearing system. The rotor is flexible and has a complex shape. To obtain the nominal plant transfer functions, we perform a numerical analysis by using the finite element method(F.E.M.) for the rotor's dynamics, and make a nominal model by reducing the modes from the results. And, we have experimented on the frequency response by a closed-loop identification method, and compared it with the simulation's result on the closed-loop control system.

The gundrill is capable of machining for having large length to diameter ratio in single pass. The techniques of gundrill and gun boring began developing in the late 18th century with the need for more accurate bores in rifle, cannon, machinery part and marine part etc. The main feature of the gun drilling provides a stabilizing cutting force resultant necessary for self guidance of the drill head. A study of the accuracy and surface finish of holes produced would reveal quite useful information regarding the process. The thesis deals with the experimental results obtained during gun drilling on marine part materials for different machining conditions.
