적 요여름재배용 사계성 딸기 ‘진하’(Fragaria x ananassa Duch.) 품종은 2019년 농촌진흥청 국립식량과학원 고령지농업연구소에서 육성되었다. 2011년 경도가 높고 대과성인 중일성딸기 품종 ‘Albion’을 모본으로 하고, 모양이 좋고 고온에 강한사계성 딸기 품종 ‘고하’를 부본으로 하여 교배하였다. 2012년파종 후 육묘하여 4월 정식하였다. 정식 후 사계성, 과실크기, 경도, 당도 등을 조사하여 사계성이며, 경도가 높고 수량성이높을 것으로 예측되는 1개체를 실생선발하였다. 본 계통을 여름작형에서 2013년 우수계통 선발, 2014년 생산력검정, 2015년특성검정, 2016년 지역적응성 검정을 수행하였다. 시험결과 당도가 높아 맛이 좋으며, 품종육성 목표에 가장 근접한 이 계통을‘새봉 11호(12-6-561)’로 계통명을 부여하였다. 2019년 직무육성품종 선정위원회에서 신품종으로 선정되어 ‘진하(Jinha)’로명명되었다. ‘진하’의 초형은 반개장형이며, 초세는 중간이다. 과실모양은 원추형이며, 과색은 홍색이다. ‘진하’의 초장은 대조품종 ‘Flamenco’와 비슷하나 엽수가 많은 편이다. 그러나 화방장은 35.5 ㎝ 대조품종인 ‘Flamenco’의 24.7 ㎝보다 10.8 ㎝ 더길다. 또한 화방수는 14.4개가 출현되어 대조품종보다 4.1개가더 발생된다. ‘진하’의 평균과중은 10.1 g으로 ‘Flamenco’의 9.3g보다 0.8 g 더 무겁다. 또한 당도는 10.2 ˚Brix로 ‘Flamenco’보다 2.0˚Brix 더 높다. ‘진하’의 상품수량은 25,931 ㎏·㏊ -1로‘Flamenco’의 5,900 ㎏·㏊ -1보다 훨씬 많지만 일반적인 사계성딸기품종 수량과 유사하다. 따라서 신품종 사계성 딸기 ‘진하’는다른 사계성 품종보다 당도가 높고 모양이 좋아 제과용 시장에서 큰 인기가 있을 것으로 기대된다. Abstract - ‘Jinha’ is a new strawberry (Fragaria x ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2019. The ‘Jinha’ cultivar originates from a 2011 cross between ‘Albion’ and ‘Goha,’ both of which exhibited excellent ever-bearing characteristics, including continuous flowering and large fruits under long-day and high temperature conditions. This new cultivar was initially named ‘Saebong No. 11’ after examining its characteristics and productivity during summer cultivation between 2012 and 2016. After regional adaptability tests, ‘Jinha’ was selected from ‘Saebong No. 11’ as an elite cultivar. The general characteristics of ‘Jinha’ include intermediate, elliptic leaves, and medium growth. The fruits are conical and of a red color. The plant height of ‘Jinha’ is simiar to that of the control variety, ‘Flamenco’, but it has a lot of number of leaves. The cluster length of ‘Jinha’ was 35.5 ㎝, 10.8 ㎝ longer than 24.7 ㎝ of the control variety. The number of flower clusters of ‘Jinha’ appeared 14.4, which was 4.1 more than that of ‘Flamenco’. The average fruit weight of ‘Jinha’ was 10.1 g, which was 0.8 g heavier than that of ‘Flamenco’. The soluble solid content of ‘Jinha’ was 10.2 ˚Brix, which was 2.0 ˚Brix higher than that of ‘Flamenco’. The marketable yield of ‘Jinha’ was 25,931 ㎏· ㏊−1, 440% more than that of ‘Flamenco’ with 5,900 ㎏·㏊−1. Therefore, the new cultivar of ever-bearing strawberry ‘Jinha’ is expected to be very popular in the export or bakery market because it is high soluble solid content and good shape.

The movement behavior of fine sinter in hearth layer has been known to be influenced by suction pressure, particle size of sinter and charging condition of hearth layer i.e., the ratio of the height of upper hearth layer to that of lower hearth layer. In this study the behavior of fine sinter has been investigated using sintering pot simulator. From our experimental results, especially the charging condition among the factors has been found to have a great influence on the movement behavior of fine sinter. When the suction pressure in sinter bed was increased, the weight loss of fine sinter was increased. The weight loss of fine sinter was also decreased with the height of lower hearth layer. The optimum charging conditions are obtained as follows : (a) When the particle size of sinter in upper hearth layer is over 3 ㎜, the amount of fine sinter remains unchanged during the suction. (b) The weight loss of fine sinter in hearth layer is severe when the height of lower hearth layer is below 10 ㎜.

This research aims to confirm the importance of after-school lifelong education programs for youth with developmental disabilities by analyzing the effectiveness of lifelong education program, in improving achievement motivation and quality of life by providing psychological and emotional stability and increasing healthy interdependence. For this, lifelong education programs were carried out to five people for eight months between March to December 2018 and involved culture and arts education, vocational skills programs, and usage of community services. To measure the effectiveness of the lifelong education program, 'achievement motivation diagnostic testing questionnaire' and 'quality-of-life measurement tool for youth with developmental disabilities' were used. The results from these tests were then analyzed using paired t-tests. Also, the program log recorded after the program by the instructors was analyzed to observe changes to motivation achievement and quality of life for participants. The analyses confirmed that there were significant changes in all participants in both motivation achievement and quality of life. Based on these results, this research suggests a plan to improve future lifelong education programs for youth with developmental disabilities.

단정도/배정도 승산을 위한 200-MHZ@2.5-V 이중 모드 승산기

이종남,박종화,신경욱 한국정보통신학회 2000 한국정보통신학회논문지 Vol.4 No.5

단정도 (single-precision) 승산과 배정도 (double-precision) 승산을 연산할 수 있는 이중 모드 승산기 (dual mode multiplier; DMM)를 $0.25-\mum$ 5-metal CMOS 공정으로 설계하였다. 단정도 승산기 회로를 사용하여 배정도 승산을 연산할 수 있는 효율적인 알고리듬을 제안하였으며, 이는 배정도 승산을 4개의 단정도 부분 승산으로 분할하여 순차적인 승산-누적 연산으로 처리하는 방법을 기초로 한다. 제안된 방법은 배정도 승산기에 비해 latency와 throughput cycle은 증가하나, 회로 복잡도를 약 113로 감소시킬 수 있어 칩 면적과 전력소모 측면에서 장점을 갖는다. 설계된 DMM은 radix-4 Booth receding과 redundant binary(RB) 연산을 적용하여 설계된 $28-b\times28-b$ 단정도 승산기, 누적기 그리고 동작모드 선택을 위한 단순한 제어회로 등으로 구성되며, 약 25,000개의 트랜지스터와 $0.77\times0.40-m^2$의 면적을 갖는다. 시뮬레이션 결과, 2.5-V 전원전압에서 200-MHZ의 클록 주파수로 안전하게 동작할 수 있을 것으로 예상되며, 평균 전력소모는 배정도 승산모드에서 약 130-㎽이 다. A dual-mode multiplier (DMM) that performs single- and double-precision multiplications has been designed using a $0.25-\mum$ 5-metal CMOS technology. An algorithm for efficiently implementing double-precision multiplication with a single-precision multiplier was proposed, which is based on partitioning double-precision multiplication into four single-precision sub-multiplications and computing them with sequential accumulations. When compared with conventional double-precision multipliers, our approach reduces the hardware complexity by about one third resulting in small silicon area and low-power dissipation at the expense of increased latency and throughput cycles. The DMM consists of a $28-b\times28-b$ single-precision multiplier designed using radix-4 Booth receding and redundant binary (RB) arithmetic, an accumulator and a simple control logic for mode selection. It contains about 25,000 transistors on the area of about $0.77\times0.40-m^2$. The HSPICE simulation results show that the DMM core can safely operate with 200-MHZ clock at 2.5-V, and its estimated power dissipation is about 130-㎽ at double-precision mode.

‘다하’는 농촌진흥청 국립식량과학원 고령지농업연구소에서 2018년도 육성한 사계성 딸기 신품종이다. ‘다하’는 ‘새봉3호’ 를 모본으로 하고 ‘고하’를 부본으로 2012년 교배하여, 고온 장일 조건에서 과실이 크고 화방이 연속적으로 출현되는 우수한 사계성 개체를 선발한 것이다. 대관령의 여름재배 작형에서 2015년부터 2016년까지 생산력 및 특성검정을 거쳐 ‘새봉 10호’로 계통명을 부여하고, 지역적응성 시험을 거쳐 ‘다하’로 명명하였다. ‘다하’의 초형은 반개장형이며, 초세가 왕성하다. 과실모양은 원추형이며, 과색은 붉은 색이다. ‘다하’의 화방장은 25.3 cm 로 대조품종인 ‘고하’보다 14.1 cm 더 짧았다. 또한 ‘다하’의 출현화방수는 12.3개로 ‘고하’의 15.0개보다 2.7개 더 적게 발 생하였다. ‘다하’의 평균과중은 12.0 g으로 ‘고하’의 9.0 g보다 3.0 g 더 무거웠다. 그러나 과실품질은 두 품종 모두 비슷하였다. ‘다하’의 상품수량은 45,972 kg·ha-1로 ‘고하’의 21,481 kg·ha-1 보다 214% 증수되었다. 따라서 ‘다하’는 대과성이며 수확량이 많은 사계성 품종으로 농가보급 시 높은 소득이 기대된다. ‘Daha’ is a new strawberry (Fragaria x ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2018. The ‘Daha’ cultivar originated from a cross between ‘Saebong No. 3’ and ‘Goha’, which showed excellent everbearing characteristics, including continuous flowering habit and big size fruit under long-day and high-temperature conditions in 2013. This cultivar was initially named ‘Saebong No. 10’ after examining its characteristics and productivity in summer culture from 2014 to 2016. After regional adaptability tests, ‘Daha’ was selected from ‘Saebong No. 10’ as an elite cultivar. The general characteristics of ‘Daha’ included spreading type, elliptic leaf, and vigor in growth. The fruits were conical in shape with red color. The cluster length of ‘Daha’ was 25.3 cm, which was 14.1 cm shorter than that of ‘Goha’. The number of flower clusters of ‘Daha’ was 12.3, which was 2.7 less than that of ‘Goha’. The average fruit weight of ‘Daha’ was 12.0 g, which was 3.0 g heavier than that of ‘Goha’. However, fruit quality was similar in both varieties. The marketable yield of ‘Daha’ was 45,972 kg·ha-1, which was 214% more than that of ‘Goha’ with a yield of 21,481 kg·ha-1. Therefore, Daha is a big fruit and high-yielding variety of everbearing strawberries, and high income is expected from the distribution of farms.
