CAPM explains the rate of return for the risk asset by $\beta$, systematic risk. There are some assumption in CAPM. But CAPM can not explain the movement of stock price sufficiently due to limitation of the assumptions. Therefore many scholars study which variables with the exception of $\beta$ effect on the rate of return of risk asset for supplementing this limitation by using PER, size of firm etc.. But it will be natural that PER, size of firm etc. to be determinant factors of $\beta$ also effect on the abnormal rate of return, because PER, size of firm etc. used in their studies already effect on determination of $\beta$, . That is, the determinant factors of $\beta$ effect on determination of abnormal rate of return according as $\beta$, effects on abnormal rate of return. Therefore, this study tests empirically how the determinant factors of $\beta$, effect on determination of$\beta$, ,and how $\beta$ and the determinant factor of $\beta$ effect on the abnormal rate of return in CAPM.

GPS type portable-alarm-system is composed of satellite receiving equipment, signal transmission equipment, etc. Time errors occur because of the processing methods of the satellite receiving equipment and signal generator, the positional error of GPS itself, etc. With the recent rise of train speed, it becomes very important to secure the stability of portable-alarm-system from time errors, The present study estimated errors caused by the structure of portable-alarm-system, GPS errors. etc., and verified them. In addition, it examined the effects of such errors on portable-alarm-system according to train speed.

Rail defects(Corrugation, shelling, etc) are occurred by the Rail with wheel contact stress. Rail grinding is maintaining of optimal rail profile to use special rail grinding machine to remove rail defect. The benefits of rail grinding enforcement, improve track safety, improve track steering and rail life, improve ride comfort and reduce noise, etc. Actually when rail grinding plan apply to field track, we should consider a lot of function before determination, such as grinding method, grinding pass number, removing metal volume, etc. because each track has various characteristics. Therefore it is important that the determination of rail grinding strategy for optimum and economic before enforcement.

According to the development of smart technologies such as smart phones, tablet PC, and SNS communication, the necessity of smart work that can change the working environments in organizations has been emphasized. However, while there are many organizations that wish to adopt smart technologies, there are those that have been skeptical until now about its potential success. Leaders may especially have different viewpoints concerning the efficacy and effectiveness of smart work depending on the industries, characteristics of the work, etc. Therefore, this research looks to investigate whether there may be differences between leaders (manager, project manager, supervisor, etc.) and non-leaders (team member, staff, etc.) group in accepting smart working through empirical and exploratory approaches.

Asthma is one of the most common chronic disease of childhood. Although an improved understanding of the pathophysiology of asthma has had a positive impact on the treatment and management of the disease, there has been a gradual but significant increase in asthma mortality. Also, mother's caring type is the essential factor in management of the child with asthma. The purpose of this study is to identify and understand the caring patterns of mathers of children with Athma by Q methodology. As a research method, 35 Q-statements were collected through individual interviews and review of related literatures. 37 subjects were interviewed and the data were analyzed by the PC QUANL program with principal component analysis. The were 3 different caring types classified as follows : Type I was the therapeutic compliance obeying type, compliancing medication and preventing cold etc. Type II was the physical strengthening type, taking Chinese medicine and folk remedy etc. Type III was the environment control type, managing house and environment clearly and ventilating room air etc. Therefore, it needs considering above each type in nursing care of the family and children with asthma.

In the literatual studies on the pruritic dermatoses, the results were as follows. 1. In Oriental medicine, Pruritic dermatoses is belong to the cartegory of the 'Pung- soyang(風瘙痒)', 'Pungyang(風痒)', 'Yangpung(痒風)', 'Sinyang(身痒)' etc. 2. Pruritic dermatoses is occurring idiopathically without primary lesion, marked by intense itching. 3. The pathogenic factors of Pruritic dermatoses is divided two parts. One is exo- genous pathogenic factors which including the wind-cold and wind-heat The other is endogenous pathogenic factors which including the blood-deficiency, the blood-heat, the wetness-heat of liver & gallbladder, the spleen-asthenia and impairment of the liver & kidney etc. 4. In the prescription of Pruritic dermatoses, it was used Gyejimahwanggakbantang(桂枝麻黃各半湯) in exogenous pathogenic factors, was used Danggyiyumja(當歸飮子), Sopungsan(消風散), Bangpungtongsungsan(防風通聖散), Yanghyulyunbuyum(養血潤膚飮) etc.

In this paper, the details of electric traction voltages which are widely used for metro and mainline trains are presented. The problems encountered in catenaries, pressure of the pantograph pan, catenary contact cross sectional area, materials etc are well covered. Catenary height from the rail for main line, bridges, sheds etc is discussed. The catenary running details and switching of one catenary to another are explained. The dead zones in 3 phase grid as well as in DC are presented here. The pantograph structure, blades, shoes etc. for AC/DC EMUs are dealt. The schematic diagram for electrification systems used for railways are given and explained with typical electrical parameters of Indian Railways.

The purpose of this study is to investigate the visual sensibility of wedding dress. There are 28 kinds of costume samples from photographs in wedding dress magazines. They were divided into simple, accent and decorative design. The Semantic Differential method was used in this study to measure them. The semantic scale was composed of 20 pairs of adjective words. The data were analyzed by factor analysis, ANOVA, MDS and regression analysis. The results are as follow; 1. Factor analysis has extracted five factors which consist of the visual sensibility of wedding dress. The factors are High quality, Cuteness, Femininity, Decoration and Modernness. 2. There were significant differences in the visual sensibility of wedding dress and demographics.3. The evaluative dimensions of the visual sensibility of wedding dress were identified by Cute-Adult and Simple-Decorative. 4. Preference was related to what are wearing-desirable, chic, cute, natural and beautiful, etc., and the wearing desire was related to what are favorite, lively, chic, special and gracious, etc. The noble sensibility was related to what are elegant, cute, feminine and chic, etc.

The radar signal processing procedure is divided into the pre-processing such as frequency down converting, down sampling, pulse compression, and etc, and the post-processing such as doppler filtering, extracting target information, detecting, tracking, and etc. The former is generally designed using FPGA because the procedure is relatively simple even though there are large amounts of ADC data to organize very quickly. On the other hand, in general, the latter is parallel processed by multiple DSPs because of complexity, flexibility and real-time processing. This paper presents the radar signal processor design using FPGA which includes not only the pre-processing but also the post-processing such as doppler filtering, bore-sight error, NCI(Non-Coherent Integration), CFAR(Constant False Alarm Rate) and etc.
