  • Automatic repeated recalling from individual computing equipments such as PC and workstations, to access ATM networks may result in call overload to networks. Call overload causes to waste network resources and fail to meet user call processing QoS requirements. We evaluate two call connection request methods: the back-off recall method(BRM) which makes recall with random waiting time after rejection, and the direct recall method(DRM) which repeats call connection request whenever call request is rejected. We evaluate their performances by simulation and it shows that as the total number of attached terminals to each access node increases, BRM performs better than DRM in terms of the call acceptance level and effective network bandwidth utilization.

  • In order to design man-machine system, communication system and other tasks that require information, we need to understand the characteristics of hyman short-term memory (STM). Thus, the purpose of this thesis is to investigate the influences of information stress and retention time on human performances and their relation- ships for STM of visual invormation. Eight subjects performed the computer monitering with STM task. The results showed that performance on serial recall from STM get wores and response time (and completion time) on information transmission by recall from STM increase as information stress and retention time increase. Also, there existed inverse proportional relationship between recall performance and response time (and completion time).

  • The purpose of this study was to evaluate the validity of various dietary methods. Dietary intake of 24 patients on regular diet was investigated by three methods. One method was a precise weighing method, the others were 24-hour dietary recall method and convenient dietary questionnaries. The results obtained are summarized as followes ; 1) There were no significant differences in mean nutrient intake of subjects among three dietary survey methods. 2) The validity coefficient between the precise weighing method and 24-hour recall method, ranging from 0.26(fat) to 0.59(carbohydrate) showed significant correlation for carbohydrate, vitamin A, thiamin, riboflavin and ascorbic and intakes. 3) The validity coefficient between precise weighting method and covenient dietary questionnaires, ranging from 0.14(fat) to 0.80(vitamin A), showed a significant correlation for most nutrients. 4) Female showed higher correlation between the precise weighing method and 24-hour recall method than male subjects for most nutrients. However, there was no significant sexual difference of correlation between weighing method and convenient method. 5) The correlation coefficient between the precise weighing method and the other two methods by age group showed younger sujbects have a higher significant correlation than older subjects for most nutrients.

  • Critical evaluation of energy intake data from dietary studies is difficult but important. To investigate the underreporting of total energy intake, we analyzed the one-day dietary intake data collected by 24-hour recall method from 550 elderly Koreans aged 60 years or older. Underreporting was addressed by computing the ratio of energy intake (EI) to estimated basal metabolic rate (BMRest). EI : BMRest ratio was found to be 1.38 for, men and 1.33 for women, with about 14% of men and women classified as underreporters. Underreporting of energy intake was highest in men and women who were overweight, had lower family income, or no school education. For men, the most significant variables to predict the ratio of energy intake to estimated basal metabolic. rate (EI : BMRest) were weight status, members of household, alcohol consumption and age, while income and education level were most significant for women.

  • This experimental research explores the effect of background music of TV documentary which can be classified as channel factor in the field of media effect, on audience's recall memory, flow, arousal of interest, evaluation of documentary. Most previous researches of media effect focused on the effect of sender factor and message factor on audience's memory, understanding, acquirement of knowledge, attitude, action. However the number of researches on the effect of background music on audience's various dependent variables is extremely limited, especially it is very difficult to find studies on the effect of background music of TV documentary on audience. Therefore this research tries to find the effect of background music of TV documentary on audience's recall memory, flow, arousal of interest, evaluation. For this research of experiment, 2 groups of subjects composed of 101 university students were exposed to 2 different video clips of TV documentary, one with background music, the other without it, After this experiment, Questions which were designed to measure audience's recall memory, flow, arousal of interest, evaluation were asked and analysed. This research found that background music of TV documentary increased audience's flow, degree of interest and raised evaluation, However meaningful effect of background music on audience's recall memory was not found.

  • Background: Cervical cancer is the second most common cancer among Malaysian women with an ASR of 17.9 and a mortality rate of 5.6 per 100,000 population in 2008 (GLOBOCAN, 2008). The 5 year prevalence was estimated to be 14.5 per 100,000 population. As the second most common cancer affecting productive females, cervical cancer imposes an impact to the socioeconomic aspect of the country. However, the poor uptake of cervical cancer screening is a major problem in detecting early pre-cancerous lesions and thus, delay in initiating treatment for cervical cancer. Realizing the urgency to increase the uptake of PAP smear, besides enhancing the promotion of PAP smear screening for women above 35 years old, the call-recall system for pap smear screening had been piloted in one of the suburban districts which aimed to improve regular participation of women for cervical and breast cancer screening. This is of public health importance as identifying the best feasible option to increase patient's respond to participate in the screening program effectively in our setting will be helpful in implementing an organized regular population based screening program tailored to our setting. The pilot program of cervical cancer screening in Klang was an opportunity to assess different options in recalling patients for a repeat pap smear to increase their participation and adherence to the program. Methods and Results: This was a population based randomized control trial. Women aged 20-65 years in the population that matched the inclusion and exclusion criteria were re-called for a repeat smear. There are four different intervention groups; letter, registered letters, short messages services (SMS) and phone calls where 250 subjects were recruited into each group. Samples were generated randomly from the same population in Klang into four different groups. The first group received a recall letter for a repeat smear similar to the one that has been given during the first invitation. The intervention groups were either be given a registered letter, an SMS or a phone call to re-call them. The socio-demographic data of the patients who came for uptake were collected for further analysis. All the groups were followed up after 8 weeks to assess their compliance to the recall. Conclusions: The study will provide recommendations about the most effective methods for recall in a population based pap smear screening program on two outcomes: i) patients response; ii) uptake for repeat pap smear.

  • The types of errors corrected by a Korean spelling and grammar checker can be classified into isolated-term spelling errors and context-sensitive spelling errors (CSSE). CSSEs are difficult to detect and to correct, since they are correct words when examined alone. Thus, they can be corrected only by considering the semantic and syntactic relations to their context. CSSEs, which are frequently made even by expert wiriters, significantly affect the reliability of spelling and grammar checkers. An existing Korean spelling and grammar checker developed by P University (KSGC 4.5) adopts hand-made correction rules for correcting CSSEs. The KSGC 4.5 is designed to obtain very high precision, which results in an extremely low recall. Our overall goal of previous works was to improve the recall without considerably lowering the precision, by generalizing CSSE correction rules that mainly depend on linguistic knowledge. A variety of rule-based methods has been proposed in previous works, and the best performance showed 95.19% of average precision and 37.56% of recall. This study thus proposes a statistics based method using a conditional probability model with dynamic window sizes. in order to further improve the recall. The proposed method obtained 97.23% of average precision and 50.50% of recall.

  • This paper examines the performance of assessing sponsors and non-sponsors recall and recognition at the 2008 Beijing Olympic Games perceived by Korean and Chinese university students. Using a sample of 1,573 respondents, a survey was administered in Seoul and Beijing before and after Games to compare the recall and recognition that changed between two periods. The findings reveal that the effectiveness of the 2008 Beijing Olympic sponsorship has was lower than we expected. Results were founded that while Samsung(mobile), Coca-cola, McDonald's, and Visa achieved the desired sponsorship marketing effectiveness in Korea. On the other hand, non-sponsors of Nike, Dell, AIG, Samsung(computer) and Hyundai led to obtain the benefit and resulted in increasing consumer confusion as to who is a sponsor. In China, Samsung, Coca-cola, Lenovo, Volkswagen, Visa, and PICC achieved the desired sponsorship marketing effectiveness. On the other hand, Lining, Nokia, KFC, China Merchants Bank had some impact on the effectiveness of a rival brand from an official sponsor's product category. The paper concludes by considering some issues for sponsorship marketers.

  • The study empirically analyzed the effects of content attitudes and recall on digital signage advertising appeal (information appeal vs. image appeal) and interactivity level (low vs. high). As a result, first, it was found that a moderately low level of interactivity had a positive effect on content attitudes and recall than when the level of digital signage was extremely high. In addition, at moderately low levels of interactivity, information appeals had higher content attitudes and recalls than image appeals. Second, the content of image appeal has a positive effect on attitude when the digital signage level of interactivity is high, and the image recall ad and information appeal ad have negative effects on recall. Third, the low level of interactivity of digital signage has a positive effect on the content attitude and recall of information appeal. With the advent of digital media in recent years, concerns about how to construct the level of interactivity and information content on a strategic level are increasing in practice. The results of this study are expected to suggest the direction of the strategic grounds for this.
