'Self-esteem' is defined as 'the lived status of one's individual competence and personal worthiness in dealing with the challenges of Life over Time' and high self-esteem is associated with self-confidence, effectively coping, well-being, and responsibility. The first purpose of this study was to identify the concept of self-esteem and to investigate the relationship with self-esteem and responsible environmental behaviors (REB). According to the results, it was found that 'self-esteem' is considered as one of the influential factors on REB and self-esteem enhancement is essential for the responsible choice and determination of environments. The second purpose was to analyse the level of self-esteem in High School students. The mean scores of merits and demerits for all the students involved (402) were 14.58 and 14.91 respectively. By applying the t-test, the two scores were not so different: thus the mean of self-esteem was found to be at a median level. The number of adove-average, average and below-average levels were 114, 163 and 125 respectively. From now on, the development of strategies to enhance self-esteem is urgently needed.

Purpose: This study was conducted to investigate the relationship of self-resilience, academic self-concept and test anxiety in undergraduates. Method: The participants were 403 undergraduates in H, C University in G City, and K University in S City. Data were collected from March 1 to April 30, 2012, and analyzed using SPSS/WIN 18.0. Results: The mean score per item for self-resilience was 2.77. The mean academic self-concept score was 3.17 and the mean score for test anxiety was 2.38. Self-resilience showed a negative correlation with test anxiety (r=-.186, p<.001) and a positive correlation with academic self-concept (r=.312, p<.001). Academic self-concept showed a negative correlation with test anxiety (r=-.353, p<.001). Conclusion: The findings of this study indicate that self-resilience and academic self-concept enhancement programs should be developed to reduce test anxiety in undergraduates and that further study should be done on the effects of such programs.

Objectives : This study is for suggesting the data base for help mother and child improve the oral health enhancement action from understanding child's oral health enhancement action from mother's oral health education experience and researching the effects of mother's oral health enhancement action on child's oral health enhancement action. Methods : The subject was 220 children and mothers of some kindergarten in Jeollabuk-do, Korea out of convenience'sampling. The results were collected by carrying out a survey out of self record method from visiting the kindergarten from June 24th to July 12th. and were analyzed. Results : 1. The mother's and child's oral health enhancement action was satisfactory in the factor of 'toothbrushing', 'oral hygiene care item' and 'periodic visits' in case the subjects have experienced oral health education, and that data was meaningful statistically. 2. In the oral health enhancement action practiced by mother to child from existence or absence of the mother's oral health education experience, the data was meaningful statistically in the factor of 'directly brushing its teeth more than once a day', 'washing its tongue' and 'coaching that child could keep the toothbrush not to overlap with other toothbrushes'. 3. In the factor that affect to oral health enhancement action practiced by mother to child, 'toothbrushing' and 'oral hygiene care item' were high level of the mother's oral health enhancement action, and that data was meaningful'statistically. Conclusions : The children's oral health condition could be influenced by mother's oral health knowledges and attention. Accordingly, oral health education for the mother and child has to be enforced'systematically'suited for the characteristic change of oral condition with children age groups. Also, utilizing human resources who have expertise and development of the oral health education program are needed.

A service robot can identify its own position relative to landmarks, the locations of which are known in advance. The main contribution of this research is that it gives various ways of making the self-localizing error smaller by referring to special landmarks which are developed as high gain reflection material and coded array associations. In this paper, the authors propose a set of indices to evaluate the accuracy of self-localizing methods using the selective reflection landmark and infrared projector, and the indices are derived from the sensitivity enhancement using 3D distortion calibration of camera. And then, the accurarcy of self-localizing a mobile robot with landmarks based on the indices is evaluated, and a rational way to minimize to reduce the computational cost of selecting the best self-localizing method. The simulation results show a high accuracy and a good performance.

Graphene has been widely considered a promising candidate for high-quality chemical sensors, owing to its outstanding characteristics, such as sensitive gas adsorption at room temperature, high conductivity, high flexibility, and high transparency. However, the main drawback of a graphene-based gas sensor is the necessity for external heaters due to its slow response, incomplete recovery, and low selectivity at room temperature. Conventional heating devices have limitations such as large volume, thermal safety issues, and high power consumption. Moreover, metal-based heating systems cannot be applied to transparent and flexible devices. Thus, to solve this problem, a method of supplying the thermal energy necessary for gas sensing via the self-heating of graphene by utilizing its high carrier mobility has been studied. Herein, we provide a brief review of recent studies on self-activated graphene-based gas sensors. This review also describes various strategies for the self-activation of graphene sensors and the enhancement of their sensing properties.

Objectives: The objective of this paper is to study influence of self esteem, family support and adaptation to school life on adolscents' suicidal ideation adjsuted for general characteristics effect. Methods: Using cluster sampling, 318 high school freshmen from T city were extracted as survey subjects. Independent t-test, ANOVA, Duncan test, Pearson's correlation coefficients and multiple regression analysis were applied for statistical analysis. Results: Among general characteristics, religion, family income, single-parentedness, health status and school grades were statistically significant with suicidal ideation. Controlling the above variables, increase in self-esteem (${\beta}$=-.300) and family support (${\beta}$=-.267) showed statistically significant decrease in suicidal ideation but adaptation to school life did not. Conclusions: Therefore, it is proposed that measures for enhancement of self esteem and family support to be included in development of suicide prevention programs.

Purpose: This study investigated the mediating effects of acceptance action on the relationship between diabetes distress and self-stigma in older adults with diabetes. Methods: A descriptive research approach was adopted using 187 patients diagnosed with diabetes mellitus by an endocrinology doctor. The data were collected from 26 to 31 March, 2020 and were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficient analysis, and hierarchical multiple regression. Results: The mean scores for diabetes distress, self-stigma, and acceptance action were 2.98±0.64, 2.54±0.74, and 4.16±0.35, respectively. Acceptance action partially mediated the relationship between diabetes distress and self-stigma (z=1.98, p=.024), with an explanatory power of 51.0%. Conclusion: To reduce diabetes self-stigma among old adults in diabetes distress situations, it is necessary to improve their acceptance action and develop step-by-step differentiated acceptance action enhancement programs through multidisciplinary collaborations.

This review paper outlines modern pretreatment methods used in NIR spectroscopy. The pretreatment methods can be divided into four categories. One method in is noise reduction. Smoothing is a representative method for the noise reduction. Another is baseline correction. The second derivative and multiplicative scatter correction (MSC) are most frequently employed for baseline correction. The third is centering and normalization and the last is resolution enhancement. Difference spectra, mean centering and second derivative are used in NIR spectroscopy as resolution enhancement methods. In this paper advantages and drawbacks of pretreatment methods currently used in NIR spectroscopy are discussed with many examples of NIR spectra.
