Concrete structure is recognized as the universal structuring material for its outstanding formability, economic efficiency, and strength development. However, as the ageing of field workers and the deficiency of skilled workers due to evasions from 3D business have recently become the major issues of the industry in Korea and as the materials are becoming more diversified and complicated for today's concrete structures are becoming higher, larger, and specialized, the need for practicality of construction work based on new technology and new method has greatly increased. In other words, the overall condition of today's construction business requires researches and developments on the self-compacting concrete for higher construction efficiency and quality improvements and the high-strength lightweight concrete for concrete weight reduction and reduction of area. Therefore experimental tests were performed as such compressive strength, dry shrinkage and carbonation of self-compacting concrete.

In this study, We compare material properties of Self-compacting concrete using Korean Belite cement with Japanese. Self-compacting concrete consolidates densely by virtue of its own weight at the location where concrete compaction cannot be carried out. Material properties of Korean and Japanese Belite cement are very similar but compatibility with superplasticizer and viscosity agent are some different. Before the batch mix, the compatibility must be checked as fresh concrete properties. For the concrete test results, Korean Beilite cement is suitable to product High performance concrete.

Four monkeys (Macaca mulatta) were allowed to press a lever in their cages in order to earn access to one gram pieces of Panax ginseng root. Self-administration performance on an operant schedule (mult FR20 F11) was characterized by frequent pauses and increased intertrial interval responding. When given 23 hour unlimited access to ginseng root, as well as to food and water, all animals titrated their daily intake to approximately 1.5 g/kg. Gross behavioral changes included increases in vocalization, activity, stereotyped movements, and weight loss. These patterns of behavior are typical of those seen when monkeys self-administer psychomotor stimulants. Further studies on ginseng's reward value can be conducted using this animal model.

자가 적응 시스템은 사람의 직접적인 개입 없이 자율 제어를 통한 자가 최적화 (self-optimization), 자가 치유 (self-healing) 등의 능력이 요구되고, 이러한 시스템은 시스템이 조달된 환경과 시스템 내부 상황을 고려한 적절한 적응 정책과 목표 평가를 통해 시스템의 신뢰성을 보장할 수 있어야 한다. 목표 기반의 자가 제어 시스템은 목표 만족도에 따라 시스템을 자율 제어하기 때문에 목표 기반 자가 적응 시스템에서의 목표 만족도(goal satisfaction) 평가는 매우 중요하지만 기존의 연구들의 목표 만족도 평가 방법에서는 환경 변화가 반영되지 않는다는 한계가 있다. 본 논문에서는 목표 모델에서의 상위 목표에 대한 하위 목표들의 기여도에 따라 가중치를 부여하고 시스템의 외부 환경 변화에 따라 가중치를 동적으로 변경하는 방법을 제안한다. 이를 통해 기존의 목표 평가 방법보다 사용자의 요구가 잘 반영되고 신뢰성 높은 평가가 가능하다.

NLP 분야에서 적극 활용되기 시작한 Transformer 모델을 Vision 분야에서 적용하기 시작하면서 object detection과 segmentation 등 각종 분야에서 기존 CNN 기반 모델의 정체된 성능을 극복하며 향상되고 있다. 또한, label 데이터 없이 이미지들로만 자기지도학습을 한 ViT(Vision Transformer) 모델을 통해 이미지에 포함된 여러 중요한 객체의 영역을 검출하는 saliency map을 추출할 수 있게 되었으며, 이로 인해 ViT의 자기지도학습을 통한 object detection과 semantic segmentation 연구가 활발히 진행되고 있다. 본 논문에서는 ViT 모델 뒤에 classifier를 붙인 모델에 일반 학습한 모델과 자기지도학습의 pretrained weight을 사용해서 전이학습한 모델의 시각화를 통해 각 saliency map들을 비교 분석하였다. 이를 통해, 클래스 분류 학습 기반 전이학습이 transformer의 saliency map에 미치는 영향을 확인할 수 있었다.

Background: Early detection is a critical part of reducing the burden of breast cancer and breast self-examination (BSE) has been found to be an especially important early detection strategy in low and middle income countries such as Malaysia. Although reports indicate that Malaysian women report an increase in BSE activity in recent years, additional research is needed to explore factors that may help to increase this behavior among Southeastern Asian women. Objective: This study is the first of its kind to explore how the predicting variables of self-efficacy, perceived barriers, and body image factors correlate with self-reports of past BSE, and intention to conduct future breast self-exams among female students in Malaysia. Materials and Methods: Through the analysis of data collected from a prior study of female students from nine Malaysian universities (n=842), this study found that self-efficacy, perceived barriers and specific body image sub-constructs (MBSRQ-Appearance Scales) were correlated with, and at times predicted, both the likelihood of past BSE and the intention to conduct breast self-exams in the future. Results: Self-efficacy (SE) positively predicted the likelihood of past self-exam behavior, and intention to conduct future breast self-exams. Perceived barriers (BR) negatively predicted past behavior and future intention of breast self-exams. The body image sub-constructs of appearance evaluation (AE) and overweight preoccupation (OWP) predicted the likelihood of past behavior but did not predict intention for future behavior. Appearance orientation (AO) had a somewhat opposite effect: AO did not correlate with or predict past behavior but did correlate with intention to conduct breast self-exams in the future. The body image sub-constructs of body area satisfaction (BASS) and self-classified weight (SCW) showed no correlation with the subjects' past breast self-exam behavior nor with their intention to conduct breast self-exams in the future. Conclusions: Findings from this study indicate that both self-efficacy and perceived barriers to BSE are significant psychosocial factors that influence BSE behavior. These results suggest that health promotion interventions that help enhance self-efficacy and reduce perceived barriers have the potential to increase the intentions of Malaysian women to perform breast self-exams, which can promote early detection of breast cancers. Future research should evaluate targeted communication interventions for addressing self-efficacy and perceived barriers to breast self-exams with at-risk Malaysian women. and further explore the relationship between BSE and body image.

Objectives Body image distortion is found in eating disorder and obesity and there are some evidence that schizophrenia is associated with body image distortion. This study sought to find whether schizophrenic patients report more body image distortion than healthy individuals and whether it is related with symptomatology. Methods A total of 88 inpatients with schizophrenia and 88 healthy controls were recruited. Weight, height, and body image accuracy were assessed in all participants, and assessment of mood, psychotic symptom severity and self-esteem, and personal and social performance scale were conducted. Results The patients with schizophrenia had higher Body Mass Index (p < 0. 001) and underestimated their body size more than controls (26.14% vs. 5.13%, p < 0.001). Multiple regression analysis showed that lower depressive symptoms and higher scores of general psychopathology predicted underestimation of body size. Conclusion Weight gain and metabolic syndrome are common adverse events of pharmacological treatment of schizophrenia. Thus, underestimation of body size among patients with schizophrenia may interfere with effort to lose weight or seek weight reduction programs. Clinicians need to consider possible unterestimation of underestimation of body size in patients whose general symptomatology is severe.

This study compared levels of health and dietary behavior practices and health beliefs according to the stage of weight loss behavior change of Korean male workers. A self-administered survey questionnaire was collected from 411 male adult workers residing in Seoul, Kyeonggi, Chungcheong region. Practices of health related behavior, including smoking, drinking, exercise, work related physical activity, and dietary behavior according to dietary guidelines were evaluated. In addition, the levels of perceived benefit, perceived barrier, perceived susceptibility, perceived seriousness, and perceived cue to action from the health belief model were measured according to the stages of weight loss behavior change. Significant differences in BMI, level of daily exercise, and practices of dietary behavior according to dietary guidelines were observed among stages of weight loss behavior change. Subjects who were in action/maintenance stage showed a more desirable level of health behavior and health belief model variables, except perceived barrier. Based on the findings of this study, it is suggested that subjects with different stages of behavior change need an appropriate specific nutrition education method and material for improvement of nutrition education efficacy.
