Purpose: The purpose of this study was to explore differences in health belief by compliance level with breast self-examination (BSE) and the predictors of BSE compliance among women. Method: Using a convenience sampling method, 163 women were selected for the sample. Data were measured for each participant during the period between December 2008 and February 2009, and analyzed by chi-square test, t-test, Kruskal-Wallis test with post hoc, and logistic regression analysis. Samples were categorized into three groups by the compliance level of BSE for the last 6 months: Never-performers (i.e, women who had never performed BSE), irregularly-performers (i.e, women who performed BSE at least once), and regularly-performers (i.e, women who performed monthly BSE). Result: Significant differences were reported among never-performers, irregularly-performers and regularly-performers correlated to age, level of education, mammography, ultrasonography, clinical examination, benefit, and confidence. There was no significant difference between irregularly-performers and regularly performers. The significant factor influencing compliance with BSE was 'confidence', which explained 33.7% of the variance in compliance with BSE. Conclusion: Women who had more confidence in their ability to perform BSE were more likely to practice BSE. It is necessary to develop the strategy to enforce woman's confidence in complying with BSE.

This research investigates listening strategies and the relationship between the employment of strategy and listening proficiency of Korean EFL middle school students. One hundred and four middle school students (N = 104) participated in this study and their strategy use was assessed through a questionnaire adapted from Oxford's (1990) SILL and O'Malley and Chamot (1990). To measure listening proficiency, the English Listening Ability Test designed by 15 city and provincial offices of education in Korea was used. The results show that students employed a moderate use of strategies; compensation strategies were used most frequently and metacognitive strategies were used the least frequently. Significant differences were found in the use of implicit strategy among different listening proficiency groups, but not in their use of behavioral strategy. Furthermore, there were significant differences in the use of implicit memory, cognitive and compensation strategies among groups of students with different listening proficiencies, but not in their use of metacognitive strategy. The results from multiple regression analysis indicate that implicit strategy use could play an important role in listening comprehension. The findings suggest the need for additional research to explore the effect of listening strategy training for English language learners.

The mouse as an input device has undoubtedly brought convenience to users due to its intuitiveness and simplicity, but it also brought unprecedented issues such as carpal tunnel syndrome (CTS). As a result, the necessity of alternative input devices that put less strain on the wrist, while still providing the convenience of a conventional mouse, has emerged. Unfortunately, there have been several research about alternative devices to replace a mouse, however, they showed inconsistent results. This study suggests that those inconsistent results may stem from the type and the difficulty of tasks used in previous studies. Therefore, we designed this study to compare the performance and perceived workload of three input devices (Mouse/Trackball/Touchpad) in each condition in terms of task type (Targeting/Tracking) and difficulty level (Easy/Hard). The results indicated that there were significant performance differences and no significant workload differences among the three devices, and the interactions were observed in some conditions. These results can provide users with practical guidelines to choose the optimal input device according to their needs or purpose.

The purpose of this study was to examine the relationship between academic personality types and academic achievement in an effort to seek teaching and learning strategies geared toward improving the academic achievement of students. The subjects in this study were 400 dental hygiene students who were randomly selected from three-year colleges in Gyeonggi Province. Their academic personality types and academic achievement were investigated, and the findings of the study were as follows: 1. As for the academic personality types of the subjects, the inquiry-oriented type was most dominant, and the ideal-oriented one was least common. 2. In regard to differences in academic personality types according to academic year, the inquiry-oriented type was most common in every academic year, and there were statistically significant differences(p<.05). 3. As to differences in academic personality types according to academic achievement, the best academic achievement was found in the norm-oriented type, and there were statistically significant differences(p<.05). 4. Concerning differences among the subjects in academic satisfaction according to academic personality types, there were no statistically significant differences(p>.05). When the above-mentioned findings of the study were pieced together, the academic achievement of the subjects varied with their academic personality types, and it's consequently necessary to make an effort to apply different teaching methods and learning methods according to their preferences. As there are individual variances among students in achievement goal, preferred learning method and experience though they study in the same space with different learning methods, the development of student guidance programs tailored to academic personality types seems necessary.

This study investigated the effects of a healthy image on the preference and intake frequency of meat and animal products. The study looked into beef, pork, chicken, sausage, mackerel, cutlass fish, croaker, tuna, squid, shrimp, clams, fish cakes, eggs, milk, yogurt, ice cream, and cheese. A total of 359 usable surveys given to elementary school students, college students, and adults were collected using a convenient sampling method. While milk had the healthiest image, sausage had the least healthy image. The respondents preferred yogurt the most and sausage the least. The intake frequency of eggs was the highest and clams the lowest. The healthy image, preference, and intake frequency for all studied foods showed significant differences across both gender and age. The relationship between healthy image and preference was significant for all foods, and a healthy image always had a positive influence on preference. The relationship of healthy image and intake frequency was significant in 14 foods except for mackerel, cutlass fish, and tuna. Also a healthy image created a positive effect on the intake frequency of 14 foods.

The prime objective of many facial wrinkle-reduction treatments is to achieve visible improvement. Thus the visibility of before/after treatment differences is often part of an efficacy assessment. This paper investigates whether the background knowledge of the people acting as observers in such assessments is of impact on the results: e.g. the subjects themselves are familiar with their faces, skin professionals have much experience in judging skin quality, and thus both might be more sensitive to small changes. In a clinical study 44 Female subjects were regularly treated during a period of 12 weeks with one of three wrinkle-reduction methods: K, Land M (placebo). Photographs were taken before treatment and at 6 and 12 weeks. The photographs were judged by 3 types of observers:ㆍ24 Lay observers were given the 0＆6-week and the 0＆12-week photo pairs of all subjects to indicate the one with the least wrinkles in a two-alternative forced-choice (TAFC) procedure.ㆍThe subjects themselves were given the 0＆6-weel and the 0＆12-week pair of their own photos (8 replications) to indicate the photo with the least wrinkles (TAFC).ㆍA trained panel of skin professionals (N=3) each gave 9-point Fitzpatrick wrinkle-severity scores for all individual 0-week and 12-week photos. We found that the lay observers perceived the same differences as the subjects themselves: significant improvements after 12 weeks for treatment K (p<0.0005 and p=0.005, respectively), no visible effects for treatments Land M, and, most importantly, a significant difference between treatments K and M/placebo (p=0.02 and p=0.04, respectively). Also the trained panel found this difference between K and M (p=0.013), but here it was due to a significant deterioration over time of the 'placebo-treated' wrinkles (M, p=0.03). Thus in conclusion we have found no indications that extra knowledge - in the form of familiarity with the own face or in the form of professional training - results in the identification of more treatments that show significantly visible wrinkle-reduction.

Objective: To assess the potential clinical utility of in-vivo 31P magnetic resonance spectroscopy (MRS) in patients with various malignant and benign breast lesions. Materials and Methods: Seventeen patients with untreated primary malignant breast lesions (group I), eight patients with untreated benign breast lesions (group II) and seven normal breasts (group III) were included in this study. In-vivo 31P MRS was performed using a 1.5 Tesla MR scanner. Because of the characteristics of the coil, the volume of the tumor had to exceed 12 cc (3×2×2 cm), with a superoinferior diameter at least 3 cm. Mean and standard deviations of each metabolite were calculated and metabolite ratios, such as PME/PCr, PDE/PCr, T-ATP/PCr and PCr/T-ATP were calculated and statistically analyzed. Results: Significant differences in PME were noted between groups I and III (p=0.0213), and between groups II and III (p=0.0213). The metabolite ratios which showed significant differences were PME/PCr (between groups II and III) (p=0.0201), PDE/PCr (between groups I and III, and between groups II and III) (p=0.0172), T-ATP/PCr (between groups II and III) (p=0.0287), and PCr/T-ATP (between groups II and III) (p=0.0287). There were no significant parameters between groups I and II. Conclusion: In-vivo 31P MRS is not helpful for establishing a differential diagnosis between benign and malignant breast lesions, at least with relatively large lesions greater than 3 cm in one or more dimensions.

The purpose of this study was to segment consumers based on sales promotion orientation and examine the differences between the consumer segments on shopping behaviors and promotion usage behaviors. A total of 462 responses collected from a questionnaire survey to subjects aged over 20s were analyzed. Cluster analysis on sales promotion orientation identified four groups including rational group(21%), active group(28％), insensitive group(22.1%), and interest group(28.9%) of sales promotion. ANOVA revealed significant differences among the four groups on shopping behaviors(information seeking, store visit, and clothing purchase) and promotion usage behaviors(the usage level of sales promotion, impulse buying, brand switching, and store switching). The active and interest groups were more actively seeking information than the other two groups were. The active group was most affected by sales promotion showing the highest impulse buying and brand and store switching behaviors, and the interest group was most active on store visit and clothing purchase. The insensitive group was the least engaged in all the behaviors.

Objectives: The purpose of this study is to analysis differences of heart rate variability (HRV), body composition, digital infrared thermal imaging (DITI), and electro pulse graph by whether there are some causes of dysmenorrhea or not. Methods: We studied 89 patients who took at least one test among HRV, Body composition, DITI, and electro pulse graph visiting Kyung Hee University Hospital at Gangdong from March 1, 2014 to May 7, 2019. Results: There were statistically significant differences in Low frequency (LF), LF norm and High frequency norm (HF norm) of HRV between primary dysmenorrhea patients and secondary dysmenorrhea patients. There were statistically significant differences in Body Mass Index (BMI) and body fat percentage of Body composition between two groups. But both BMI were included in normal range. There were no statistically significant difference in DITI results. And there was significant difference of Estimated circulation resistance (ECR) between two groups. Conclusions: The results suggest that hormone imbalance of secondary dysmenorrhea patients can affect HRV results. And because of high ECR, phlegm pathology can be more considered in secondary dysmenorrhea patients. Further study should be conducted to confirm the results of body composition and DITI differences.
