Background: Diet and Nutrition are important modulators of bone health in men and women. We investigated the associations between frequency of food intake among certain food groups and bone mineral density (BMD) in a large population of Korean adults. Methods: We used the data from Korea National Health and Nutrition Examination Survey during 2008 to 2009. Participants were aged 20 years and over. BMDs were measured at lumbar spine and femoral neck with dual-energy X-ray absorptiometry. Dietary and supplement intakes were assessed by food-frequency questionnaire. We used multiple linear regression analysis to evaluate the relationships between annual food-frequency of each food group and BMD. Results: After adjustment of multiple covariates, femoral neck and lumbar BMD significantly increased as the frequency of fruit consumption increased in both men and women. Frequency of other carbohydrates consumption was significantly associated with greater femoral neck and lumbar BMD for women. Frequency of milk and dairy product consumption was significantly associated with greater femoral neck BMD in men. Other food groups, however, had no significant associations with BMDs. Conclusion: Frequent consumption of fruit has a positive association with BMDs in men and women. Milk and dairy products and other carbohydrates also had positive effects on BMD for men and women, respectively.

최근 전시는 과거의 지루하고 딱딱하던 이미지에서 벗어나 관객이 직접 느끼고 참여할 수 있는 대중에 친근한 문화의 한 축으로자리 잡았다. 이와 함께 전시의 형태와 방향 역시 다양화되고, 여러 가지 시도가 이루어지고 있다. 또한, 이러한 변화와 함께 전시콘텐츠의 표현 방법 역시 다양화 되고 있으며, 그 표현에 있어 형태적, 물리적 표현보다 감성적, 심리적 표현 및 체험을 유도하는방법이 주목받고 있다. 본 연구는 전시콘텐츠 표현에 빛과 색채를 적용하여 관람객에서 보다 효과적으로 전시의 내용과 분위기, 감성등을 표현할 수 있는 방법을 제시하고자 한다. Exhibition which was a boring and rigid image once has recently hold a place as an intimate culture to the public suchthat audiences can feel and participate in exhibition at first hand. Along with this, forms and directions of exhibition becomediversified, and various attempts have been made. In addition, with such changes, ways of expressing exhibition contentsbecome diversified as well and ways of inducing sensible and psychological expressions and experience are receivingattention rather than formal and physical expressions. This study aims to provide audiences with ways of being able to moreeffectively expressing exhibition contents, atmospheres, sensibility and so on by applying lights and colors to in expressionof exhibition contents.

With the recent surge in the autonomous driving market, the significance of lane detection technology has escalated. Lane detection plays a pivotal role in autonomous driving systems by identifying lanes to ensure safe vehicle operation. Traditional lane detection models rely on engineers manually extracting lane features from predefined environments. However, real-world road conditions present diverse challenges, hampering the engineers' ability to extract adaptable lane features, resulting in limited performance. Consequently, recent research has focused on developing deep learning based lane detection models to extract lane features directly from data. In this paper, we classify lane detection models into four categories: cluster-based, curve-based, information propagation-based, and anchor-based methods. We conduct an extensive analysis of the strengths and weaknesses of each approach, evaluate the model’s performance on an embedded board, and assess their practicality and effectiveness. Based on our findings, we propose future research directions and potential enhancements.

Background: This study was performed to evaluate the association between food intake frequencies and long-term blood glucose control using glycated hemoglobin (HbA1c) in Korean diabetes. Methods: This study used data collected from the 4th Korea National Health and Nutrition Examination Survey. Patients with diabetes were defined as people who responded “yes” to the question “Are you currently suffering from diabetes?” or in whom serum fasting glucose was 126 mg/dL or more. Using the food frequency questionnaire and HbA1c in surveys,we examined the association between the annual food-frequencies of each food group and long-term blood glucose control. Results: After adjustment for other covariates, HbA1c decreased significantly as the frequency of the intake of fish increased in each population (P = 0.001 for all, P = 0.043 for men, P = 0.001 for women). The intake of mackerel played an especially important role in the control of diabetes. Among women, HbA1c decreased as the frequency of intake of legumes increased (P = 0.029) and increased as the frequency of intake of staple carbohydrates increased (P = 0.015). On the other hand, any intake of other food groups showed no significant relationship with HbA1c. Conclusion: Frequent intake of fish in all populations and legumes in woman were associated with good glycemic control in diabetics. Frequent intake of carbohydrates was associated with elevated HbA1c in women.
