This study measured the accompanying rating, recall, and recognition of advertisements, which were run with different methods of spacing in the magazines. To achieve this objective the study chose a qualitative research and performed a reliable test. After the survey was completed, the advertisement recall test was performed. In addition, two days later, the recognition test was performed to the survey respondents and data on the memory of respondents on the advertisements was collected. As a result, rating, recall and recognition of the advertisement's were significantly different by the various forms of advertisements in the magazines. In the advertisement rating and recall by the advertisement printing forms, rather than the regular printing form of running the target advertisement for two pages in a role and the irregular printing form, the continuous printing form was confirmed to be more effective. In addition to that, in the form of running continuous target advertisements for six pages in a role, the effects of the advertisements recall and the recognition were increased. A continuous printing form had higher outcomes on the rating, recall and recognition of advertisements. Therefore, conclusively, it gave more effects in increasing the memory of the advertisement for the consumers. The conclusion of the study provided suggestions on the forms of advertisement to stimulate the memory of consumers in the magazine advertisement.

In the United States, when NHTSA initiates the vehicle defect investigation, the most of automotive manufactures voluntary start their vehicle's recall campaign immediately. However, in the domestic market, NGOs, medias and even the National Assembly complaint the attitude of domestic and foreign makers tendencies of retardation of recall campaign. Also there were criticism for the manufacturer's concealing or downsize of their vehicle defects to the publics. In general, the manufactures may wait until MLIT's decision to recall orders. Therefore, in this study, from the survey of foreign countries legal recall systems and it is recommended reinforcement of the current vehicle management law to promote more frequent voluntary recall campaign from makers. In this study, it is also includes summarize all previous recall related research works and proposes the more stringent regulations to punish of concealing or downsize their vehicle safety defects.

Today many owners of Web sites are looking to user's satisfaction survey as a key means of measuring the usability of a Web site. While it is preferred for it simplicity and ease of use, this survey method is not without potential risks. This paper focuses on showing that the existing practice of questionnaire-based usability measurement is subject to human recall errors, and that such flaws can be reduced when the questionnaire survey is followed by the users hands-on experience of the site. An empirical study was conducted, and the results indicate that the above speculation holds true. Even if respondents felt highly confident about their responses on a recall survey, a hands-on experience with a focal Web site increased the extent to which the respondents were satisfied with the shopping mall site. This indicates that a user's perception of the quality of a Web site may be distorted or lost as time goes by. In addition, the findings have shown that the use of the verbal protocol analysis method can reveal critical information that can help track the root causes of Web site usability problems, thereby helping to develop site enhancement strategies. The paper concludes with directions for future research.

This study was conducted to compare dietary intake and quality obtained by food frequency questionnaire(FFQ) and 24-hour recall method among 1249 Korean adults living in rural area. The survey was conducted twice; first with 65-items FFQ by interview and then with 24-hour recall method two years later. Nutrients intake estimated from two dietary methods showed significant difference. For nutrients except fat and iron, average intake value estimated from the FFQ were significantly higher than that from the 24-hour recall method(p<0.001). Ranking of the subjects by nutrient intake levels obtained by two methods were significantly correlated, but correlation coefficients were low. Percentage of subjects in the lowest or in the highest quintile by 24-hour recalls who belong to the nearest two categories by FFQ ranged from 45% to 61%, while the percentage falling into the opposite category ranged from 7% to 15%. Subjects' percentile rank of nutrient intake by 24-hour recall correlated with their average rank of nutrient intake by FFQ. Information on food groups by two method were not comparable because of the limited number of food items in FFQ. For most nutrients, RDA% or NAR from FFQ were higher than those from 24-hour recall, but INQ from 24-hour recall were higher than those from FFQ. From the results, results of 24-hour recall method seems to be useful in classifying subjects according to their nutrient intake if sample size is large enough.

In this paper, we compare three models (logistic regression, Random Forest, and XGBoost) for predicting stroke occurrence using data from the Korea National Health and Nutrition Examination Survey (KNHANES). We evaluated these models using various metrics, focusing mainly on recall and F1 score to assess their performance. Initially, the logistic regression model showed a satisfactory recall score among the three models; however, it was excluded from further consideration because it did not meet the F1 score threshold, which was set at a minimum of 0.5. The F1 score is crucial as it considers both precision and recall, providing a balanced measure of a model's accuracy. Among the models that met the criteria, XGBoost showed the highest recall rate and showed excellent performance in stroke prediction. In particular, XGBoost shows strong performance not only in recall, but also in F1 score and AUC, so it should be considered the optimal algorithm for predicting stroke occurrence. This study determines that the performance of XGBoost is optimal in the field of stroke prediction.

The purpose of this study was to analyze the dental treatment of patients with disabilities, especially according to the frequency of general anesthesia, and to propose the improvements in oral care. The subjects of the present study were 85 patients including age, sex, medical condition, dental treatment and the number of general anesthesia. The patients were divided into regular and irregular check groups according to their follow-up patterns. These two groups were compared for the frequency of general anesthesia and the type of repeated treatment. The results showed that restorative treatment was superior in numbers under first visit of general anesthesia. And more general anesthesia was performed in the irregular recall check group compared with the regular recall check group. This survey suggest that easy access to a dental clinic and the convenience of treatment is needed. On the other hand, there is a time limit on the dental care for disabilities by the dentist. Therefore oral care training program should be simultaneously provided for parents to improve the efficiency of dental care at home. In conclusion, efforts should be made for more comprehensive and effective dental care including regular recall check and preventive home care for disabilities.

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.

Accurate assessment of nutrient adequacy of a population should be based on usual intake distribution of that population. This study was conducted to adjust usual nutrient intake distributions of a single 24-hour recall in 2001 Korean National Health and Nutrition Surveys (KNHNS) in order to determine the magnitude of limitations inherent to a single 24-hour recall in assessing nutrient intakes of a population. Of 9,960 individuals who provided one 24-hour recall in 2001 KNHNS, 3,976 subjects provided an additional one-day 24-hour recall in 2002 Korean National Nutrition Survey by Season (KNNSS). To adjust for usual intake distribution, we estimated within-individual variations derived from 2001 KNHNS and 2002 KNNSS using the Iowa State University method. Nutritionally at risk population was assessed in reference to the Dietary Reference Intakes for Koreans (KDRIs). The Korean Estimated Average Requirement (Korean EAR) cut-point was applied to estimate the prevalence of inadequate nutrient intakes except for iron intakes, which were assessed using the probability approach. The estimated proportions below Korean EAR for calcium, riboflavin, and iron were 73%, 41%, and 24% from usual intake distribution and 70%, 51%, and 39% from one-day intake distribution, respectively. The estimated proportion of sodium intakes over the Intake Goal of 2,000 mg/day was 100% of the population after adjustment. The energy proportion from protein was within Korean Acceptable Macronutrient Distribution Ranges (Korean AMDR), whereas that of carbohydrate was higher than the upper limit and that of fat was below the lower limit in the subjects aged 30 years or older. According to these results, the prevalence of nutritional inadequacy and excess intake is over-estimated in Korea unless usual intake distributions are adjusted for one-day intakes of most nutrients.

회상법과 빈도법을 이용하여 식이섭취조사를 할 경우 영양소에 따라 다소 차이는 있으나 일반적으로 모든 영양소에서 빈도법이 회상법 보다 개인의 섭취량이 과다하게 평가되는 경향을 보이고 있으며 영양소별 측정 오차가 식이조사 방법에 따라 가장 큰 차이를 보였던 영양소는 carotene이었고 이 영양소는 두 방법에 의해 추정된 값 사이에 통계적으로 유의있는 상관을 보이지 않고 있다. 그러므로 본 연구 결과는 연구 목적이 되는 영양소의 종류에 따라 식이조사 방법으로 히상법과 빈도법을 교차 선택할 수 있는영양소와 그렇지 않은 영양소가 있음을 시사하고 있다. 그러나, 본 연구는 각 방법이 지니는 상대적 타당성(validity)를 측정하는데 필요한 표준가치(reference value)가 없으므로 타당성을 측정할 수 없었고 단지 두 방법간의 차이만을 비교하는데 그치는 제한점이 있었다. 그러므로 사용된 방법의 타당성 측정을 위해서는 표준값을 제공할 수 있는 객관적인 방법인 실측법(precise weights method) 등이 비록 적은 표본 규모라도 진행될 필요성이 있다. 한편, 더 나아가 조사방법의 신뢰도 측정을 위해서는 정확성(precision)을 보기 위해 한 방법을 여러번 반복 조사하여야 방법의 정확성 등이 검토될 수 있겠다. 이러한 기초연구를 위한 많은 투자와 노력이 있어야만 역학조사에서 이용된 식이조사 방법의 신뢰성 확보가 가능함을 본 연구결과는 시사하고 있다.
