Purpose: The purpose of this study was to compare physical self-concept, academic self-concept and depression among obese and over-weight and normal weight children. Methods: The 6th grade children in two elementary schools (n=287) completed self-report questionnaires measuring self-concept and depression. Results: The mean score of depression and self-concept in normal weight children were 9.76 and 92.59. In obese and over-weight children, depression and self-concept were 12.31 and 86.69 respectively. Subjects who were obese and over-weight showed significantly lower scores of physical self-concept (t=-4.621, p<.001) but not significantly low in academic self-concept (t=-1.065, p=.288) than normal weight children. Meanwhile, this study shows that subjects who were obese and over-weight were significantly higher level of depression than subjects in normal weight (t=2.480, p=.014). Conclusion: In conclusion, obese and over-weight children showed negative aspects in the developmental course. This study demonstrates that obese and over-weight children should be treated as a risk group who needs any professional help such as a school mental health program for normal development.

The article shows that the concept 'weight' and the concept 'heaviness' give rise to different abstractions in the sense of Piaget and that these two concepts are differentiated by set-theoretic devices. The failure of differentiation of these two concepts 'weight' and the 'heaviness' can cause the failure of learning of the difference between reflective abstraction and empirical reflective abstraction. To explain the Piagetian abstrcation in a classroom, the author suggests to use the concept 'color' instead of the concept 'weigtht'.

스트리밍 데이터는 시간에 따라 지속적으로 생성되는 데이터 시퀀스이다. 시간이 지남에 따라 데이터의 분포 또는 컨셉이 변화할 수 있으며, 이러한 변화는 분류 모델의 성능을 저하시키는 요인이 된다. 점층적 적응적 학습 방법은 컨셉 변화의 정도에 따라 현재 분류 모델의 가중치를 조절하여 업데이트를 수행함으로써 컨셉 변화에 대한 분류 모델의 성능을 유지할 수 있게 한다. 그러나, 컨셉 변화의 정도에 맞는 적절한 가중치를 결정하기가 어렵다는 문제점이 있다. 본 논문에서는 컨셉 변화에 따른 적응적 가중치 조정에 기반한 동적 앙상블 방법을 제안한다. 실험 결과는 제안한 방법이 다른 비교 방법들에 비해 높은 성능을 보여줌을 입증한다.

The importance of weight discrimination for people with obesity has been highlighted by research which has found that more than 40% of those living with obesity have experienced weight discrimination. Evidence suggests that weight bias among obese individuals puts their health at risk more than health issues caused by obesity itself. Although bias, stigma, and discrimination towards individuals living with obesity are factors that make it difficult for them to lose weight, weight bias and stigma among healthcare professionals are common, causing individuals living with obesity to avoid treatment and potentially exacerbating obesity-related health issues. The concept that one's own efforts matter contributes to stigma, discrimination, and bias. This issue will be more frequent among primary care providers treating individuals living with obesity; thus, it is important to acknowledge the issues of bias, stigma, and discrimination towards individuals living with obesity and to seek out solutions. In this review, I will discuss the concept of weight bias, stigma, and discrimination, the problems they cause, and seek solutions to weight prejudice, stigma, and discrimination.

Purpose: This study explored the relationships of maturity fears and appearance interest(interest in appearance, interest in weight) with self-concept among girls with precocious puberty. Methods: The participants for this study were 120 elementary school students (8 to 10 years old) and their parents from two hospitals located in Chungcheong Province. Data were collected from January to February 2019 using self-reported questionnaires. The collected data were analyzed using descriptive statistics, the independent t-test, the Mann-Whitney U test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression analysis in SPSS for Windows version 23.0. Results: Statistically significant negative correlations were found between self-concept and maturity fears (r=-.34, p<.001) and interest in weight (r=-.29, p=.001). Maturity fears were identified as a factor affecting the self-concept of girls with precocious puberty (β=-.34, p<.001). This variable explained 11.5% of the variance in the self-concept of girls who experienced precocious puberty. Conclusion: This study confirmed that maturity fears had a major influence on self-concept in girls with precocious puberty. The results of this study can be used as basic data for the development of a psychosocial nursing intervention program for girls who experience precocious puberty.

This paper aims to offer a solution based on semantic document classification to improve e-Government utilization and efficiency for people using their own information retrieval system and linguistic expression Generally, semantic document classification method is an approach that classifies documents based on the diverse relationships between keywords in a document without fully describing hierarchial concepts between keywords. Our approach considers the deep meanings within the context of the document and radically enhances the information retrieval performance. Concept Weight Document Classification(CoWDC) method, which goes beyond using exist ing keyword and simple thesaurus/ontology methods by fully considering the concept hierarchy of various concepts is proposed, experimented, and evaluated. With the recognition that in order to verify the superiority of the semantic retrieval technology through test results of the CoWDC and efficiently integrate it into the e-Government, creation of a thesaurus, management of the operating system, expansion of the knowledge base and improvements in search service and accuracy at the national level were needed.

Purpose: The purpose of this case study was to examine the effects of an intervention based on the concept of proprioceptive neuromuscular facilitation (PNF) on the weight-supporting ability, fear of falling, and stair-walking ability of stroke patients. Methods: One pretest, three intervention sessions, and one posttest were conducted. In the tests, weight-supporting ability, manual muscle strength, the fear of falling, and the time to go up and down a 'ㄱ'-shaped stair-walking machine were measured and compared. The intervention was implemented for 30 minutes per day for three days in combination with general rehabilitation. The intervention was planned and implemented based on the concept of PNF, and the goal was for the subjects, after their consent, to walk backward down the stairs. Results: After the intervention, functional improvement was seen in weight-supporting ability and the fear of falling felt when walking down the stairs. Whereas the subjects could not perform the task of walking down the stairs on the 'ㄱ'-shaped stair-walking machine in the pretest, they could perform the task in the posttest, and their stair-climbing speed was greater than before the intervention. Conclusion: This study verified that a PNF-based intervention can improve stroke patients' weight-supporting ability and stair-walking ability. Therefore, this intervention can be clinically applied to stroke patients.

This study was carried out to construct accurate and scientific system of assessment indicators in selection of National Trust conservation areas, which was new concept of domestic environment movement and offer the raw data of new analytic method by introducing the fuzzy theory and weight for overcoming the uncertainty of ranking decision. To transform the Likert's scale granted to assessment indicators into the type of triangular fuzzy number(a, b, c), there was conversion to each minimum(a), median(b), and maximum(c) in applying membership function, and in using the center of gravity and eigenvalue, there was to decide the ranking. The rankings of converted values applied a mean importance and weight were confirmed that they were generally changed. Therefore, the ranking decision was better to accomplish objective and rational ranking decision by applying weight that was calculated in grouping of indicator than to judge the singular concept and to be useful in assessment of diverse National Trust site. In the future, because AHP, which was general method of calculating weight, was lacked, there was to understand the critical point to fix a pertinent weight, and to carry out the study applying engineering concept like fuzzy integral using $\lambda-measure$.

본 연구에서는 초등학교 4-6학년을 대상으로 첫째, 비만도에 따른 아동의 심리사회적 적응과 체력 수준의 차이를 밝히고, 둘째, 비만도와 체력이 과체중 이상 아동의 심리사회적 적응에 미치는 영향을 살펴보았다. 과체중 이상 아동은 '한국 비만 아동의 신체 활동과 건강(KOCPA)' 연구의 비만 캠프 프로그램에서, 대조군 아동은 서울 시내 초등학교에서 표준 성장도표의 체질량지수를 기준으로 모집되었다. 심리사회적 변인으로 자아 효능감 검사(식이 자아 효능감, 체중 조절 효능감, 신체 효능감), 자아개념검사, 소아용 삶의 질 검사가 사용되었으며, 신체 계측 및 체력은 직접 측정되었다. 연구 결과, 비만도가 증가할수록 심리사회적 적응과 체력 수준이 낮은 것으로 나타났다. 또한 과체중 및 비만 아동은 정상체중 대조군에 비해 유의하게 낮은 효능감 및 자아개념, 삶의 질을 보고하였다. 과체중 및 비만 아동을 대상으로 심리사회적 적응에 비만도와 체력, 두 변인의 상호작용이 미치는 영향을 알아본 결과, 체력이 좋을수록 높은 체중조절 효능감, 신체 효능감, 삶의 질이 예측되었다. 또한 비만도와 체력의 상호작용 효과가 비만 아동의 자아개념 수준을 예측하였는데, 이는 비만도가 그리 높지 않은 아동들은 체력 수준의 향상이 자아개념을 유지할 것이라고 예측 가능하지만 비만도가 상대적으로 매우 높을 경우에는 우선적으로 비만도의 감소가 우선적으로 이루어져야 함을 시사한다. 본 결과를 바탕으로 본 연구의 함의와 한계점에 대해 논의하였다.

Weight reduction for an automobile body is being sought for the fuel efficiency and the energy conservation. One way of the efforts is adopting Ultra Light Steel Auto Body (ULSAB) concept. The ULSAB concept can be used for the light weight of an automobile door with the tailor welded blank (TWB). A design process is defined for the TWB. The inner panel of door is designed by the TWB and optimization. The design starts from an existing component. At first, the hinge and inner reinforcements are removed. In the conceptual design stage, topology optimization is conducted to find the distribution of variable thicknesses. The number of parts and the welding lines are determined from the topology design. In the detailed design process, size optimization is carried out to find thickness while stiffness constraints are satisfied. The final parting lines are determined by shape optimization.
