This study analyzes the effects of the number of angles and bends on resistance in a conductor-embroidered stitch circuit for efficient power transfer through a conductor of wearable energy harvesting to study changes in power lost through connection with actual solar panels. In this study, the angle of the conductive stitch circuit was designed in units of 30°, from 30° to 180°, and the resistance was measured using an analog Discovery 2 device. The measured resistance value was analyzed, and in the section of the angle where the resistance value rapidly changes, it was measured again and analyzed in units of 5°. Following this, from the results of the analysis, the angle at which the tension was applied to the stitch converges was analyzed, and the resistance was measured again by varying the number of bends of the stitch at the given angle. The resistance decreases as the angle of the stitch decreases and the number of bends increases, and the conductor embroidery stitch can reduce the loss of power by 1.61 times relative to general embroidery. These results suggest that the stitching of embroidery has a significant effect on the power transfer in the transmission through the conductors of wearable energy harvesting. These results indicate the need for a follow-up study to develop a conductor circuit design technology that compares and analyzes various types of stitches, such as curved stitches, and the number of conductors, so that wearable energy harvesting can be more efficiently produced and stored.

기념관은 특정 역사적 사건이나 인물, 시대, 현장을 기억하기 위한 곳이며, 잊고 있던 기억과 만나 현재의 자신을 생각해 볼 수 있는 공간이다. 기념관에서는 사람들이 자발적으로 추모의 경험을 할 수 있도록 특정 역사적 대상을 설명할 수 있는 기반을 마련하는 데 주력한다. 그러한 맥락에서 기념관에서의 교육기능은 더욱 중시된다. 기념관에서 이루어지는 교육은 크게 전시관을 안내하고 관람을 지원하는 교육서비스부터 대상과 주제 등에 따라 강의, 체험활동, 답사 등으로 운영되는 다양한 프로그램, 기념관이라는 물리적으로 벗어나 기념 대상의 학습기회를 제공할 수 있는 아웃리치(outreach) 프로그램으로 구분될 수 있다. 현재 대표적인 역사 교육기관으로 활성화되고 있는 독립기념관, 백범김구기념관, 경상북도독립운동기념관은 방문자 유형 및 내‧외부 환경을 고려하여 기관의 특성에 맞게 교육기능을 수행하고 있다. 이사부기념관은 해양인물 이사부를 통해 우리나라의 동해 개척과 독도수호의 역사를 알리고, 국민들의 영토의식 함양을 위해 강원도 삼척에 만들어질 공간이다. 이사부기념관이 국민이 즐겨 찾는 역사학습공간으로 성장하기 위해서는 우선 기관의 설립목적에 따라 관람객이 기억하고 학습해야 하는 목표와 내용을 명확히 정해야 한다. 더불어 이사부기념관을 방문할 관람객 유형과 수, 즉 수요를 예측하 고 이에 맞춘 이사부기념관만의 교육서비스와 프로그램을 기획할 필요가 있다. 이를 위해서는 현재 활성화되고 있는 기념관들의 현황을 참고하여 중장기적인 차원 에서 운영 전략이 마련되어야 하며 전시 및 교육시설과 전문 인력, 예산이 수반되어야 한다. 그래야만 이사부기념관이 영토 수호의식을 함양할 수 있는 대표적인 역사교육기관이자 관람객이 즐겨 찾는 에듀테인먼트(edutainment) 기관으로 자리 매김할 수 있을 것이다.

Fruits are good sources of vitamins, minerals, fiber, and phytochemicals, which are known to reduce serum lipids, oxidative damage, and blood pressure as well as improve blood glucose control. The purpose of this study was to estimate nutrient quality indices of fruits by carrying out a critical analysis of pre-existing methods according to their nutritional compositions. Four methods were used to assess the nutrient indices of 26 fruits, which are frequently consumed by Koreans based on the fourth Korean National Health and Nutrition Examination Survey (2009). Naturally nutrient rich score (NNR), nutrient rich food (NRF), nutrient adequacy score (NAS), and nutrient density score (NDS) were used to calculate nutrient quality indices. The Korean Nutrition Society Food Composition database of fruits based on 100 g edible portions was used. The algorithm of each method included the mean percentage of daily values (Dietary Reference Intakes for Koreans, 2010) for particular nutrients based on consumption of 1,900 kcal/day. The relative score indicated that strawberries, kumquat, and lemon had high nutrient quality indices. In addition, mango, lemon, persimmon, strawberry, apricot, and tangerine fruits are rich in antioxidant nutrients such as β-carotene, vitamin C, vitamin E, and selenium. However, scores of nutrient quality indices did not imply that higher scores of particular fruits are superior. We suggest moderate seasonable consumption a variety of fruits. Our results can be used as a reference for consumers when they choose fruits.

The purpose of this study was to investigate the status of domestic and foreign power blogs that serve as professional source of information and to clarify the difference of the criteria for the certification and selection of power blogs. The study also analyzed the configuration of contents and the characteristic of categories of the power blogs. Eleven domestic blogs were examined, of which ten were certified as power blogs on several portal sites and one blog was operating in English. Furthermore twelve foreign blogs were examined, of which ten blogs were selected from the graded list of www.alexa.com for the Fashion Power Blog TOP 20 adopted on www.telegraph.co.uk in 2009, and two noticeable blogs were selected additionally. Data were analyzed by both theoretical and exploratory studies. The exploratory study was conducted by fourteen majors, who took interest in the blogs and were divided into two groups to look at the domestic and foreign sites, from 12 October to 12 November in 2010. The types of blogs were classified by frequency analysis of interactivity, interest provision, information provision and purchase capability. The investigators checked the type of the contents of each blog and the frequencies were used for the classification type. The analysis showed that the frequencies were in the order of information provision, followed by interest provision, and purchase capability for foreign blogs, while interest provision was followed by information provision for domestic blogs. Interactivity, interest provision, information provision and purchase capability were generally reflected in foreign blogs. Rather than interest provision and information provision, however, interactivity and purchase capability were reflected relatively weakly in domestic blogs.

Crop production can be secured by the cycle of green manure crops as an alternative of the chemical fertilizer. Recently, rapeseed (Brassica napus L.) has been cultivated in the south part of Korea for the production of biodiesel. In this research, we focused on recycling rapeseed residue, which is produced after harvesting the rapeseed for biodiesel, as a potential source of nitrogen to the succeeding crop. Pot experiment was conducted to evaluate the effects of winter rapeseed as green manure on mineralization and uptake of nitrogen to the succeeding corn (Zea mays L.). Result showed that total nitrogen and C/N ratio of rapeseed at the harvesting stage was 0.54% and 63, respectively. The incorporation of rapeseed without decomposition period slightly inhibited nitrogen uptake to the succeeding corn compared to those with 30 days decomposition period. The pH and EC values of soils increased by increasing the period of decomposition of rapeseed from 5.2 to 6.4 and from 0.05 dS/m to 0.21 dS/m, respectively. Significant amounts of NH₄⁺ and NO₃⁻ are released by incorporation of rapeseed. The succeeding corn took up 86% and 88% of inorganic nitrogen released from the rapeseed with and without decomposition period, respectively. The overall results suggested that the utilization of rapeseed residue as green manure can be an alternative source of nitrogen in corn-rapeseed double cropping system.
