After a short historical resume, screening is discussed on the basis of the current philosophy of Life insurance compaines in leading countries. This is followed by considerations with regard to the future in areas of major bearing on Life insurance screening which have emerged as important within the last decade. HIV-antibody testing is dealt with from the screening point of view followed by aspects regarding the applicability of tumour marker use in Life insurance medicine. Last but not least genetic testing will be addressed, taking into account prospects for the future, as well as the resulting responsibility in medical and underwriting terms. The major considerations and suggested guidelines can be summarized as follows: 1) Screening in Life insurance is a prerequisite for underwriting and is a well-functioning selection instrument. 2) Screening technologies are medically well defined and have to follow general clinical rules, also in the future. 3) Screening parameters should follow the patterns of diseases according to age and risk groups. 4) Screening parameters for prognostic use are legitimate as long as they are considered in conjuction with clinical medical observations and rules. 5) Screening technologies of a sensitive nature require very special rules for handling in the sense of "consequential ethies". 6) Screening parameters like HIV-antibody testing require ongoing scientific feedback in their new testing dimensions. 7) Screening in the form of genetic testing is as yet not used in Life insurance; its potential future role in Life insurfance medicine must, however, be discussed responsibly and in time. 8) Screening enables the insurance industry to rule out possible antiselection and provide for equal knowledge on the part of the insurance applicant and the insurer about impairements which shorten life expectancy. 9) Screening, informed consent, counselling and confidentiality must go hand in hand both now and to an even greater extent in the future.

This paper provides an in-depth examination of the relationship between cinema and Giorgio Agamben's aesthetics and philosophy. Intersecting Agamben's key concepts including gesture, mediality, biopolitics, historicity, and profanation with historical and aesthetic dimensions of cinema, I argue for his ambivalent view on cinema and visual media. On the one hand, Agamben linked cinema and visual media to his discussion on biopolitics and spectacle as he considered them as apparatus for capturing and controlling gestures. On the other hand, he also argued that cinema could restore the image with capacity to preserve and recuperate gestures based on his consideration of montage as cinema's key aesthetic and technical component (an operation of profanation) and his Benjaminian thought on the ways in which montage suspended linear flow of images and activated an alternative memory of them. Drawing on history of cinema and optical devices in the 19th and early 20th centuries as well as examples of found footages of filmmaking predicated upon stoppage and repetition of images, I argue that Agamben's concept of potentialities can be extended into his thought on cinema and visual media apparatuses in general.

In this paper, we propose an algorithm for generating lightning paths, which are more realistic than those of random tree based algorithm and faster than a physically based simulation algorithm. Our approach utilizes physically based Dielectric Breakdown Method (DBM) and approximates the electric potential field dramatically to generate the lightning path. We also show a guide path method for the lightning to avoid obstacles in a complex scene. Finally, our method renders fast and realistic lightning by considering physical characteristics for the thickness and brightness of the lightning stream. Our result of the lightning path shares similarity to natural phenomenon by having about 1.56 fractal dimensions, and we can generate the lightning path faster than a previous physically based algorithm. On the other hand, our method is difficult to apply on the real-time games yet, but our approach can be improved by performing the path generation algorithm with GPU in future.

UWB (Ultra Wide Band) refers to a system with a bandwidth of over 500 MHz or a bandwidth of 20% of the center frequency. It is robust against channel fading and has a wide signal bandwidth. Using the IR-UWB based ranging system, it is possible to obtain decimeter-level ranging accuracy. Furthermore, IR-UWB system enables acquisition over glass or cement with high resolution. In recent years, IR-UWB-based ranging chipsets have become cheap and popular, and it has become possible to implement positioning systems of several tens of centimeters. The system can be configured as one-way ranging (OWR) positioning system for fast ranging and TWR (two-way ranging) positioning system for cheap and robust ranging. On the other hand, the ranging based positioning system has a limitation on the number of terminals for localization because it takes time to perform a communication procedure to perform ranging. To overcome this problem, code multiplexing and channel multiplexing are performed. However, errors occur in measurement due to interference between channels and code, multipath, and so on. The measurement filtering is used to reduce the measurement error, but more fundamentally, techniques for removing these measurements should be studied. First, the TWR based positioning was analyzed from a stochastic point of view and the effects of outlier measurements were summarized. The positioning algorithm for analytically identifying and removing single outlier is summarized and extended to three dimensions. Through the simulation, we have verified the algorithm to detect and remove single outliers.

One of the suitable structural damage detection methods using vibrational characteristics are damage-index-based methods. In this study, a damage index for identifying damages in plate structures using frequency response function (FRF) data has been provided. One of the significant challenges of identifying the damages in plate structures is high number of degrees of freedom resulting in decreased damage identifying accuracy. On the other hand, FRF data are of high volume and this dramatically decreases the computing speed and increases the memory necessary to store the data, which makes the use of this method difficult. In this study, FRF data are compressed using two-dimensional principal component analysis (2D-PCA), and then converted into damage index vectors. The damage indices, each of which represents a specific condition of intact or damaged structures are stored in a database. After computing damage index of structure with unknown damage and using algorithm of lookup tables, the structural damage including the severity and location of the damage will be identified. In this study, damage detection accuracy using the proposed damage index in square-shaped structural plates with dimensions of 3, 7 and 10 meters and with boundary conditions of four simply supported edges (4S), three clamped edges (3C), and four clamped edges (4C) under various single and multiple-element damage scenarios have been studied. Furthermore, in order to model uncertainties of measurement, insensitivity of this method to noises in the data measured by applying values of 5, 10, 15 and 20 percent of normal Gaussian noise to FRF values is discussed.

Although mobile banking provides cost-saving opportunities as well as convenient banking experience for customers, today's banks still face challenges when deploying the technology because a good number of customers are reluctant to use mobile banking for personal reasons. This paper is an empirical investigation of the determinants of the intention to use smartphone-based mobile banking services. The determinants are grouped into two categories including personal factors and social influence factors. We conducted an empirical analysis using 751 survey responses collected from present users of mobile banking services. The results of the analysis reveal that all the personal factors have positive relationships with the intention to use mobile banking services. On the other hand, it was found that of the social influence factors, perceived herding behavior has significantly positive relationship with the intention to use smartphone-based services, whereas subjective norm is not significantly related to the intention. We provide practical as well as academic implications of the research findings.

The purpose of this study was to examine the effect of clothing color and exposure on stereotype formation of female appearance. The subjects for the research survey were 418 male and female university students in Taejon, Korea. The measuring instruments were a self-administered questionnaire and six written scripts which described a woman wearing clothing manipulated by clothing color and exposure variables. The collected data were analyzed using content analysis, T-test, crosstabs analysis, ANOVA, and Duncan's multiple range test. The results of this study were as follows. First, three dimensions (global image, appearance inference, and appearance evaluation) emerged from the subject responses. Clothing exposure had the greatest impact upon the stereotype formation of female appearance. The woman wearing exposed clothing was rated as 'sexy', 'confident', and 'glamorous' whereas the same woman wearing unexposed clothing was rated as 'slim', 'humdrum', 'ladylike', and 'neat'. Second, the gender of the subject played a role in forming stereotypes of women's appearance. The male subjects rated the woman wearing exposed clothing as 'sexy' and 'glamorous' whereas the 1em81e subjects rated the same woman as 'slim' and 'pretty'. Third, the male subjects evaluated the woman wearing expend clothing in much more negative terms than the female subjects did, indicating that men tended to use 'modesty' to evaluate the woman whereas women tended to use 'fashion trend' in addition to 'modesty' as the important criteria when assessing women dressed in exposed clothing. Fourth, the subjects judged the woman wearing exposed clothing to be an entertainer or prostitute in her early 20s. On the other hand, the subjects judged the woman wearing unexposed clothing to be either a university student or a professional business women in her mid 20s.

As a result of surveying the process for sewing, the problems involving the outlook of sewn apparels were error off the standard dimensions and uneven sizes, which verifies the need for urgent technological guidance and development. On the other hand, the majority of the businesses were operating their sewing machines at the speed of 2,000 rpm or higher. Such a conventional working method may not well reflect the properties of the stretch fabrics, causing poorer quality products. Moreover, most of the businesses were using the ball-point needles which should be replaced with appropriate ones for stretch fabric. The types of feed dog which were used most were Drop feed, Union feed, Confound feed, Differential feed in their oder. Anyway, the automatized dog should urgently replace these inefficient ones for stretch fabric. Meanwhile, the types of presser foot which were used most were Plain foot, Teflon foot, Roller foot, Ring foot in their order, which also necessitates their replacement which Teflon foot. 2. As a result of surveying the process for finishing and inspection, while the causes scores less than 3 points, those due to pressers scored more than 3 points. This results suggests that a technological guidance is needed for the pressing work. Lastly, the causes of defect due to poor outlook attributable to such notions as button or zipper and those due to the uneven sizes scored more than 3 points, which suggests that the entire of needle works should be reformed through scientific research and technological guidance.

This study investigated technology education, laboratory management and facilities in middle schools with the goal of finding problems. Ninety-six randomly selected schools and questionnaire was done to the teachers of 84 schools which have laboratory. Five of these schools received on-site inspections. The results of study are as follows : 1) 12.5% of schools have no laboratory. The average laboratory has less than 50% of the necessary equipment for total operations. laboratories are used an average of once or twice per two time frame. 2) 80%of the laboratories are located at the end of a row of regular class rooms. The most common laboratory style is classroom plus hallway($90m^2$) style. 77% of laboratories have a single entrance. 3) 69% of teachers reported the worktable arrangement to be inconvenience. 68% of the schools have 9 worktables per laboratory. 38% say the worktables are not wide enough and 36% said they were appropriate. Table dimensions range from $95{\sim}110cm$ in width and from $210{\sim}225cm$ in length. 65% of the teachers say table height is low with a range from $76{\sim}82cm$. 86% of the teachers say that the height of chair is low and the range of its measurement is from $37{\sim}47cm$. 84% of the teachers points out that laboratory is poorly lighted.

The purpose of this study is 1) to investigate the effects of Internet apparel store attributes, shopping values, Internet usage, and consumers' characteristics on consumers' Internet apparel purchasing behavior; and 2) to identify the influence of Internet apparel store attributes, Internet usage, and consumers' characteristics on the Internet apparel purchasing behavior of hedonic or utilitarian consumers. The data were collected via an online survey. A total of 4,254 Internet users participated in this survey. Only 589 out of the users' reponses were used as a sample for this research, because those users had previously experienced Internet apparel purchasing. Factor analysis revealed five dimensions of Internet apparel store attributes: site design/navigation, promotion programs, trust, product assortment/ information, and customer service. Based on the respondents' shopping value scores, we identified them as hedonic or utilitarian consumers. Through multiple regression analyses, site design/navigation and promotion programs among store attribute variables, hedonistic or utilitarian shopping values, the number of years on the Internet, income, and educational level were found to be significant predictors of Internet apparel shopping frequency. Among them, hedonistic shopping values were the best predictor of Internet apparel purchasing frequency. Based on the Internet apparel purchasers' shopping value, purchasers were divided into two groups. For hedonic Internet apparel shoppers, the number of years on the Internet, educational level, sex, age, and income were significant predictors of Internet apparel shopping behavior. On the other hand, promotion programs among store attribute variables was the only significant factor that affects utilitarian consumers' Internet apparel shopping behavior.
