The purpose of this study was to examine the effect of socioeconomic status and the children's sex on mothers'teaching strategies and their children's responses during a cooperative problem-solving task. The subjects were 15 higher SES mothers and their 5-years-old children dyads. The mothers' teaching strategies and their children's responses were videotaped during a cooperative problem solving task and analyze using a scheme developed by Kermani and Brenner. The results of this study were as follows. First, the mothers with higher SES were more likely to promote 'independence' and less likely to 'verbal prompt'direct performance' than the mothers with lower SES. Second, the children from higher SES families were more likely to refuse their mothers' assistance. Third, the mothers of boys were more likely to use the 'direct teaching'and 'modify'strategies and less likely to use 'independence promoting'strategy than the mothers of girls. Finally, girls were more likely than boys to ask questions for assistance or assurance.

In this paper, we present the new method for joint aspect inspecting system. We use the image processing and laser maker for light source. We can find the matrial joint status through processing the line pattern which is made by laser maker. To get the line pattern, in first, we did the preprocess of threshold. If the shape of line had over two segments, then the joint status is abnormal. We show our system efficency by experiment on tire facility.

Objectives: The purpose of this study was to confirm the relationship between socioeconomic characteristics and the prevalence of periodontal disease, with a focus on employment status, in a representative sample of Korean adults aged 19-39 years. Methods: Data were obtained from 3,178 adults who completed the Korean National Health and Nutrition Examination Survey, health-related questionnaires, and an oral examination. Socioeconomic, demographic, and oral health-related behavior data were adopted as independent variables. The chi-square test was used to assess differences in the distribution of socioeconomic status, oral health behavior, and nutrition factors according to employment status. Logistic regression analysis was performed to confirm the relationships between the prevalence of periodontitis and the related variables. Results: Significant differences in sex, educational level, income, marital status, smoking status, prevalence of periodontitis, number of dental check-ups in a year, and unmet dental care were confirmed according to employment status. The prevalence of periodontal disease was not significantly related to employment status. Conclusions: These results suggest a significant difference in periodontal disease according to socioeconomic factors in Korean adults. However, the prevalence of periodontal disease was not related to employment status. To prevent the progression of periodontal disease, attention should be paid to oral health, time available for dental treatment, smoking cessation, and use of floss.

Purpose: This descriptive study was done to identify the relationship between health literacy and health status and to provide basic data for developing nursing interventions for Korean-Chinese elders living in Yanbian, China. Methods: For data collection, intentional sampling of 300 elders was used. The questionnaire was composed of 5 items based on "Ministry of Health, the People's Republic of China(2008)" to measure health literacy, 33 health status items from the "Korean Health Status Measure for Elderly People" developed by Shin(2002), revised for use in China, and 9 general characteristics. Data were analyzed using SPSS Win 13.0 program. Results: Total level of health literacy was relatively high(68.7%). Elders had high scores for taking medicines according to doctor's instruction, but lower ones for full comprehension through communication with doctors. Health status was high for emotional, physical, and social function in that order. There were significant differences between general characteristics and health status for gender, age, marital status, education, family, smoking, and alcohol consumption in that order. Results of multiple regression analysis for factors influencing health status showed that self-report health level was the most influential, followed by health literacy, age, gender. Conclusion: Health literacy is the main factor affecting health promotion among minority elders indicating a need to develop health promotion programs for elders who have low health literacy.

The effects of unripe apple mask pack made from unripe apple extracts on the skin status of middle-aged women for 4 weeks were investigated. The subjects were divided into three groups: placebo mask pack as the control (PM, n = 8), apple mask pack (AM, n = 16), and apple mask pack + apple intake (AAM, n = 12). The study included a survey questionnaire, and evaluations of nutrients intakes and of skin status. Skin status was measured by Aramo-TS. After 4 weeks, facial moisture, elasticity, evenness, and wrinkle level were improved in AM and AAM. The facial moisture level (AM: $+3.13\;{\pm}\;2.73$, AAM: $+2.25\;{\pm}\;2.93$) and elasticity level (AM: $+5.81\;{\pm}\;8.27$, AAM: $+5.50\;{\pm}\;6.13$) of AM (p < 0.001) and AAM (p < 0.05) were increased. The facial evenness level (AM: $-5.25\;{\pm}\;8.13$, AAM: $-9.17\;{\pm}\;4.26$) and wrinkle level (AM: $-10.88\;{\pm}\;11.74$, AAM: $-17.83\;{\pm}\;12.22$) were significantly decreased. AAM was more effective in improving skin elasticity, evenness, and wrinkle. The skin status of PM was not changed. While the macronutrient intakes of all the subjects were not different before and after the study, the daily intakes of some vitamins (vitamins $B_6$, C, and E and folic acid) during the study were significantly increased in AAM. These findings suggested that regular use of apple mask pack was effective in improving overall skin status. Furthermore, the consumption of apples with mask pack application was much better in improving skin status.

정보통신기술 교육 운영지침이 2000년 8월에 발표된 이후 학교 현장에서 정보통신기술 교육이 실시되고 있다. 이에 따라 컴퓨터 교육과정에 대한 연구와 컴퓨터 교과서에 대한 비교 연구는 이루어졌지만 교사와 학생들의 컴퓨터 교과서 활용 현황과 그 관련 인식을 분석한 연구는 실시되지 않았다. 이에 본 연구는 충청북도 내 초등학교 5 6학년 담당 교사와 학생들을 대상으로 컴퓨터 교과서 활용 현황과 교과서의 구성 학습 내용 학습 활동에 관해 어떻게 인식하고 있는지를 알아보고, 교과서의 질적 개선을 위해 해결해야 할 과제를 제시하였다. 연구 결과, 대부분의 교사가 컴퓨터 교과서를 활용하고 있었으나 그 활용 빈도가 저조했고, 교과서를 그대로 활용하기 보다는 수정.보완하여 활용하고 있었다. 교사들은 교과서와 관련한 여러 영역 중에서 수준별 학습, 재구성 용이성, 체계성, 탐구력과 창의력 신장, 흥미유발, 자기주도적학습 능력 신장, 과제 제시 등에 대해 부정적인 인식을 가지고 있었다. 그에 비해 학생들은 용어에 대해서 부정적인 인식을 가지고 있었다. 개인 변인 중 교사는 주로 연령과 교직 경력에 따라서, 그리고 학생은 성별과 컴퓨터 교과서 활용 빈도에 따라서 유의미한 차이를 보였다.
