  • As a driving method of AC PDP, address display separated (ADS) scheme has been widely used. In ADS method, a picture of one frame is divided into eight subfields. In this paper, the effect of sustain voltage stress have been studied with several parameters. The experimental results show that sustain pulses in the previous subfield work as the stress to address discharge in the current subfield. It is also shown that as the voltage of the sustain period in the previous subfield increases, the address time lag in the current subfield decrease slightly.

  • The sustain driver for AC plasma display panel should provide alternating high voltage pulses to ignite plasma and recover the energy discharged from the intrinsic capacitance between the scanning and sustaining electrodes inside the panel. In this paper, an efficient sustain circuit employing boost-up function is proposed to achieve a faster rise-time in order to be suitable to widely used the address display period separated (ADS) driving method. The proposed circuit improves the recovery efficiency, regardless of the variation of the panel capacitance. The principle of operation, features, and simulated results are illustrated and verified on a 7.5-inch diagonal panel at 200 [kHz] operating frequency based on experimental prototype.

  • ADS(Address Display Period Separation) driving method has been considered to be the most appropriate driving technique for AC PDP. ADS driving method is composed of reset, address, sustain and erase period. Therefore, a long time should be allocated to an address period, which results in a reduction of brightness. To realize a high luminance and high picture quality, it is necessary to high speed addressing. However, address discharge time lag increases as the temperature decreases, which can cause the misfiring and low picture quality In this paper, the electric field effect and priming particle effect are investigated in order to reduce the address discharge time lag at low temperature. Address discharge time lag was reduced effectively when the priming particles are provided.

  • In the study, conceiving that signifying processes like model, setting, advertisement and description are important to promote the purchase of clothes that would satisfy consumer's desire by their expressing mode, I considered the processes of components of which fashion ads consist. As for the methods to study, I regarded the results presented from prior researches of clothing & textiles and other disciplines for the components of fashion ads and objectified their image that may be interpreted subjectively: and then, I adopted to analyse them using advertisement-semiological method to make clear the signifying processes. The results are as follow: 1. Fashion ad, one of visual symbols to transfer brand image, conveys the image with which various components are combined like model, clothes, setting and description as signs. ① the image of clothes amy be differently expressed according to social, cultural norm and individual characteristics, in the case of clothes, therefore, the signified can be regarded as the transferred image by design of the clothes① sign, and the abstract conception which may be rise to mind by the image in a ceratin culture. ② Each signifier such as countenance, line of vision, attitude and hairstyle of a model conveys different image, or the signified, respectively, and it amy operate as a sign that can express the brand image symbolically. ③ The signifiers like background, color and property symbolize the advertised merchandise of clothes and define it attribute.. 2. In the case of fashion ads, key referent systems are fashion phenomena, contemporary role image, social psychology, common morality, and social, economical and milieu.

  • Purpose: The purpose of this study was to explore the chronic patients' preferences for care near the end of life. Methods: This is a descriptive survey research, with subjects of 161 outpatients with hypertension, diabetes mellitus or chronic renal failure. Results: The majority of the subjects do not want meaningless life sustaining treatment and they report thinking positively about family or health care professional to participate in their end of life decision making process. Subjects reported preferring adequate pain management and spiritual support at the end of life. In regard to advance directives (ADs), those subjects with chronic disease report thinking positively about the necessity of ADs and its institutionalization. However, the subjects report not having the detailed information on the proper time and method of writing their ADs. Conclusion: Based on these results, educational programs on end of life decision making for chronic patients need to be developed. Also, the nurse should try to reflect the opinion of chronic patients as much as possible when make an end-of-life decision.

  • Simulation-based virtual testing is known to be a major requirement for verifying the safety of autonomous driving functions. However, in the simulation environment, there is a difficulty in that all driving environments related to the autonomous driving system must be realistically modeled. In particular, C-ITS (Cooperative-Intelligent Transport Systems) is essential for urban autonomous driving of Lv.4, but the approach to modeling for C-ITS service in the MILS (Model in the Loop Simulation) environment is not yet clear. Therefore, this paper aims to deal with V2X (Vehicle to Everything) modeling methods to effectively apply C-ITS-based autonomous cooperative driving services in the MILS environment. First, major C-ITS services and use cases for autonomous cooperative driving are analyzed, and a modeling method of V2X signals for C-ITS service simulation is proposed. Based on the modeled V2X messages, the validity of the proposed approach is reviewed through simulations on the C-ITS service use case.

  • The present study is to analyze the dimensions of affective responses according to the types of appeal in underwear advertisements and to find out the influences of affective res-ponses on the attitudes toward advertisement and brands. The research has been made by normative-descriptive survey method with the sample of 654 consumers residing in Seoul and Incheon. The data gaathered was analyzed by the methods of means, standard deviation, ANOVA, factor analysis and regression. The result are as follows : 1. There are 4 dimensions of affective responses ; Emotional dimension, Negative dimen-sion, Upbeat-activation dimension and Sexual activation dimension. 2. Affective responses to the advertising were different according to the characteristics of the consumers. According to the consumer's sex, there are significant differences in each dimension of their affective responses. To the sex appeal advertisement, man show higher degree of affective responses in Emotional, Upbeat-activation and Sexual-activation dim-ensions, while women show higher degree of affective responses in Negative dimension. 3. In case of female consumers, there are significant differences in affective responses to the both appeal type of advertisements according to consumer's age. As the age is increasing. Emotional dimension and Sexual-activation dimension are increasing, but Negative dimension is decreasing in the Ads with sex appeal. In particular, the 19∼24s age group shows strong responses in the Emotional dimension, Upbeat-activation dimension and Sexual-activation dimension to Ads with sex appeal, while it shows the lowest affective responses in Negative dimension. It represents the 19-24s age group is the most positive one to the under-wear advertisements with sex appeal. Consequently, it is proved that the Ads with sex appeal focusing on this age group can be one of the most effective advertising plans. 4. The involvement gets higher, Upbeat-ac-tivation dimension and Sexual-activation dimension are increasing both in males and female groups. But Negative dimension is in-creasing in the female consumer group of low involvement. 5. The attitudes toward advertisements and brands are comparatively stronger in the advertisements using sex appeal type. Regardless of types of appeal in the advertisements, there is a significant difference in their attitudes tow-ard Ads between male and female consumer groups. When Ads are sexual, attitudes toward Ads and Brands are stronger in the female consumer group. But males consumers show com-paratively strong attitudes toward the advertis-ements and brands in both types of appeal. 6. The age of consumers doesn't make any significant difference in their attitudes toward advertisements and brands in both types of appeal. 7. According to the involvement level of the consumers, there are significant differences in their attitudes toward advertisements. In the groups of low involvement, the female consumers show more favorite attitudes toward the advertisements with sex appeal, while the male group show more favorite attitudes toward the non-sex appeal advertisement. But there is no significant difference in consumer's attitude toward brands according to the types of appeal of the advertisement. 8. The affective responses of the consumers caused by the underwear advertisements have a respectable influence on their attitudes toward the advertisements and brands. This research represents that the advertisers should try to arise consumer's positive affective responses such as pleasant, happy, cheerful and warm-hearted emotions by the advertisements. Based on the above results of the research, it can be said that the consumer's affective responses have a strong effect not only on their attitudes toward adver-tisements but on those toward attitude toward the brands.

  • This study set out to examine message orientation in advertising expression through the content analysis of apartment sales advertisements in Busan. For this purpose, the study analyzed newspaper ads about apartment sales in the Busan area in terms of advertising appeal methods and message types. Advertising appeal methods(rational and emotional appeal) and message orientation(environmental, emotional, investment, and functional orientation) were categorized according to brands(nationwide and local brands). The findings show that most of apartment sales ads in Busan used a rational appeal method. While nationwide brands used rational and emotional appeal in similar percentage, local brands used a lot of rational appeal. Of the types of advertising message orientation, investment and emotional orientation recorded the highest percentage. Messages of investment orientation to show economic profit or premium were used most, being followed by messages of emotional orientation to show pride and happiness. These findings were interpreted to display differences in strategies for advertising expressions among brands. The findings are expected to offer useful practical implications for message strategies for apartment sales ads.

  • In the end of 1990's, future free flight technology had been developed and tested in America and government established the plan for free flight until 2017. Aircraft separation assurance must be secured essentially to avoid collision between aircrafts before Free Flight comes true. Now, Civil aircraft has rules about avoidance activity with traffic collision avoidance system (TCAS) but it can't apply to light aircraft. So there is a need about alternative method to apply light-aircraft because it has space and price problem to use TCAS. In this paper, TCAS algorithm has been modified and verified by simulating with LABVIEW program under ADS-B condition to get miniaturization and weight lighting cheaply. By simulating, collision alert algorithm is analyzed and verified with collision situation proposed by ICAO, and 100% checked for performing the alert announciation on all cases by TCAS standards.
