This study was carried out to determine the optimum seeding date for the rice(Oryza sativa L.) cultivation of the puddled-soil drill seeding, which is one of the efficient labor saving cultural methods, at the central part of Korea. Namweonbyeo, Anjungbyeo and Ilpumbyeo were seeded on four dates from April 10 to May 25, 1994 with the 15 day interval in the paddy field. In order to examine the adequate seeding date, the growth characters, yield components and yields were investigated. The coleoptile emerged 1 or 2 days earlier in Namweonbyeo than in Anjungbyeo and Ilpumbyeo, and later seeding resulted earlier coleoptile emergence. The number of seedling stands were higher in the order of Namweonbyeo, Anjungbyeo and Ilpumbyeo, was increased at the later seeding and was 81 to 88 seedlings on April 10 seeding. The plant height, number of leaves, number of tillers and dry weight at 50 days after seeding of all three cultivars were higher at later seeding. Leaf area index(LAI) were higher in the order of Ilpumbyeo, Anjungbyeo and Namweonbyeo. LAIs at the heading stage, at 30 days after heading and at 30 days before heading were higher in that order. The dry matter weight at the 30 days before heading was higher in sheath and stem than that in leaf blade, while, at heading stage, it was higher in the order of sheath and stem, leaf blade and panicle. On the other hand, at 30 days after heading, it was higher in the order of panicle, sheath and stem and leaf blade. The number of panicles per m2 was greater in the order of Ilpumbyeo, Anjungbyeo and Namweonbyeo. The ratio of ripened grain was reduced as the later seeding date. Its ratio was higher in Namweonbyeo than in Anjungbyeo and Ilpumbyeo. Yield of Namweonbyeo was lower than those of Anjungbyeo and Ilpumbyeo. Yield was decreased as the seeding date was delayed. Namweonbyeo showed the highest yield at seeding on May 10, while Anjungbyeo and Ilpumbyeo showed at seeding on April 25. The seeding date was negatively correlated with the ratio of ripened grain. while the number of seedling stands was positively correlated with the number of panicle per m2.

Prediction of retained austenite fraction is quite important in designing advanced high strength steels since retained austeniteis the source of transformation-induced plasticity. The present study investigates the phase constitution of a medium-carbonQ&P steel by comparing various approaches to the transformation stasis of bainitic ferrite and applying them to the partitioningprocess. Among them, the modified GEB approach gave the best agreement with the experimental observation, includingthe effects of heat-treatment condition and chemical composition on phase constitution. This indicates phase transformationduring partitioning can be effectively described by the physics of Gibbs energy balance approach.

성지은(Seong, Ji Eun),한규영(Han, Kyu Young),정서화(Jeong, Seo Hwa) 한국과학기술학회 2016 과학기술학연구 Vol.16 No.2

최근 국내에서도 사회 주체(주민, 사용자 등) 주도형 혁신모델이자 지역·현장기반형 혁신의 장으로서 리빙랩이 도입·적용되고 있다. 본 연구는 지역사회문제 해결을 위한 실험으로 ‘리빙랩’을 명시하고 추진된 북촌 리빙랩, 성대골 리빙랩, 건너유 프로젝트 3개 사례를 분석하였다. 각 사례의 지역문제, 문제해결 목표, 참여주체 및 주체별 역할, 리빙랩 추진체계, 의의를 분석하고 리빙랩의 유형·특성을 도출했으며, 향후 발전 방안을 모색하였다. 분석 결과 각 사례는 기술 활용 방식과 사용되는 기술의 특성은 차이가 있으나 과학기술·ICT와 지역문제 해결을 연계하고자 했으며 지역주민이 문제 발굴부터 기술 실험 및 확산·적용까지 리빙랩 전반에서 주도적인 역할을 수행하였다. 또한 공통적으로 중간지원조직의 역할이 리빙랩 운영에 중요한 요인으로 작용하였다. 각 사례는 서로 다른 리빙랩 유형을 보이고 있는데, 북촌 IoT 리빙랩은 정부/지자체가 리빙랩 활동기반 조성 또는 행위자 활동을 지원하고 프로젝트 형태로 운영된 반면, 성대골 에너지전환 리빙랩과 건너유 프로젝트는 시민사회 스스로 지역문제를 해결하기 위해 문제를 정의하고 기술을 탐색하는 형태로 진행되었다. Living Lab is being introduced and applied as an innovation model driven by social entities (residents, users, etc.) and as an innovation place based on local and field. This study analyzed three living lab cases of Bukchon IoT living lab, Seong-Daegol energy transition living lab, and Daejeon Geonneoyu project, which were designated as "Living Lab" to solve local problems. We analyzed the local problem, the problem solving goal, the role of each participant and the subject, the living lab promotion system, the significance in each case. In addition, the types and characteristics of living labs were elucidated and future development plans were discussed. The result is as follow. First, each case has a tendency to link science technology and ICT with local problem solving though there is a difference between the technologies used. Second, local residents played a leading role in the whole living lab process from problem identification to technical experimentation, diffusion and application. Third, the role of the intermediaries commonly played an important role in the operation of the living lab. Last but not least, each case has different types of living lab. Bukchon IoT living lab being operated as a project by the government / municipality to create a living lab activity-base or to support actors’ activities. On the other hand, the Seong-Daegol energy transition living lab and Daejeon Geonneoyu project were conducted by the civil society itself to define problems and explore technologies in order to solve local problems.

This experiment was carried out to obtain indispensable information to establish comprehensive cultural method of rice in direct seeding on dry paddy at Chungbuk Agricultural Research and Extension Services. Effect of seeding date on dry matter production, yield components and yield were studied. Seeding on May 5 ensured the highest maximum number of tillers, while transplanting on May 20 gave the highest rate of effective tillers. Number of effective tillers was greater in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. Lengths of upper three leaves were increased at later seeding, but leaf width was not affected by seeding date. Ratio of leaf blade weight was higher in earlier seeding during 30 days before heading but was higher in later seeding during 30 days after seeding, and was higher in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. CGR, RGR and NAR were not significantly different among seeding dates during 30 days before heading, but were lower in later seeding during 30 days after seeding. LAR was not affected by seeding date during 30 days before heading, but was higher at seeding on May 5 in heading date and during 30 days after heading. Dry weight of leaf blade, leaf sheath and culm, ear and total biomass during 30 days before heading and heading were highest in May 5 seeding. Daekwanbyeo and Hwaseongbyeo in May 5 seeding and Hwajinbyeo in April 20 seeding brought the highest yield with greater number of spikelets, higher ripening ratio and greater 1,000 grain weight, and harvest index and grain/straw ratio were Increased at earlier seeding. There were significantly positive correlations between number of panicles per m2 and LAI at 30 days before heading and heading, dry matter weight of leaf blade and total mass at heading. On the other hand, there were significantly negative correlations between seeding date and ripened grain ratio. 1,000 grain weight and yield, and between 1,000 grain weight and leaf length of 2nd, respectively.

This study was conducted to establish the cultural techniques of the puddled-soil drill seeding of race (Oryza sativa L.), which is one of the efficient labor saving cultural methods, in the central part of Korea. Seoanbyeo was seeded at three times from April 10 to May 20 with the 20 day interval in 1994. The number of seedling stands per m2 at each seeding date were 50, 90, 130 and 170. The tillering characteristics, lodging characters, dry matter production, yield components and yield were investigated. The number of days to the maximum tillering stage was reduced at the later seeding date. It was 70, 55 and 25 days in seedings on April 10, April 30 and May 20, respectively. The critical effective tillering stage was also shortened at the delayed seeding. The higher the number of seedling stands was, the higher number of tillers, the shorter duration to the maximum tillering stage and the earlier critical effective tillering stage were resulted. The number of tillers was higher at the earlier seeding date. The number of tillers was increased in the order of 50, 90, 130 and 170 seedling stands per m2. The ratios of effective tillers were 53, 61 and 63% at seeding on April 10, April 30 and May 20, respectively. The ratios were not significantly different at April 10. But the ratios in seeding on April 30 and May 20 were reduced as the number of seedling stands was increased. The weight of stem base related to lodging was the highest with 2.01g/10 plants in the optimum seeding on April 30, while it was 1.59g/10 plants in the late seeding on May 20. It was also decreased as the number of seedling stands was increased. The dry weights at 30 days before the heading stage were increased at the later seeding, while the dry weight at the heading stage was the highest at seeding on April 30 which is considered as the adequate seeding time. The dry weights at 30 days before the heading stage were increased as the number of seedling stands was increased and they were increased up to 130 seedling stands per m2 at the heading stage. The length of panicle exsertion was shortened at the later seeding. The length of panicle exsertion was increased up to 130 seedling stands. but it was shorter at 170 seedling stands. The heading dates were later at seeding on April 30 and May 20 than at seeding on April 10. They were not remarkedly different among seeding dates at 50 seedling stands, it was earlier at the higher number of seedling stands over 90. The number of spikelets per panicle was decreased at the higher number of seedling stands. The ratio of ripened grains was higher at earlier seeding than at later seeding. It was not significantly different among the number of seedling stands at the same seeding time. Yields at seeding on April 30, April 10 and May 20 were 644, 624 and 551kg/10a, respectively. The seeding on April 30, the optimum seeding time, resulted the highest yield. Rice quality was decreased due to the increase of the green kerneled rice as the seeding date was delayed.

獨逸 州間放送協定上의 放送集中規制制度에 관한 硏究

지성우 한국공법학회 2003 公法硏究 Vol.32 No.1

Die wesentlichen A¨nderungen des zum 1. Januar 1997 in Kraft getretenen deutschen Rundfunkstaatsvertrags, die bei der neuesten Revision 2002 in ihrem Kern unvera¨ndert blieben, betreffen im o¨ffentlich-rechtlichen Bereich die Ermittlung des Finanzbedarfs der Rundfunkanstalten. Die privatrechtlichen Rundfunkanstalten betreffend, lag der Schwerpunkt der U¨berarbeitung bei der Vera¨anderung der medienkonzentrationsrechtlichen Vorschriften. In Deutschland wird die Sicherung der weltweiten Konkurrenzfa¨higkeit von Rundfun-kunternehmen oftmals betont. Die Kernvorschrift des neuen Konzentrationsprinzips wird als "Marktanteilsmodell" bezeichnet. Danach kann ein Veranstalter Fernsehsendungen vorbringen, sofern er einen Zuschaueranteil von 30% nicht u¨berschreitet. Dieses Kontrollsystem wirft jedoch die wichtige Frage auf, ob die Konzentrationskontrolle durch die KEK eine u?/berma¨ßige staatliche Einflussnahme darstellt, da die Politik auf die Zusammensetzung und Gescha¨ftsfu¨hrung der KEK Einfluss ausu¨ben ko¨nnte. Daru¨ber hinaus ist auch fraglich, ob die vorhandene Meinugsmacht nur durch Vergleich der Einschaltsquoten wiederspiegelt werden kann, wenn die Sicherung der Meinungsvielfalt an rundfunkspezifischen und nicht-rundfunkspezifischen Einnahmen gemessen wird. Angesichts des multimedialen Zeitalters wa¨re es voreilig zu glauben, durch die Konzentrationsregelungen das Dilemma der notwendigen Vielfaltsicherung und des unternehmerischen Wachstums lo¨sen zu ko¨nnen. Im Zusammenhang mit der Priorita¨tsfrage bleibt jedoch immer noch offen, wie weit und mit welchen Mitteln die mo¨glichste Breite und Vollsta¨andigkeit der gesellschaftlichen Meinungen sichergestellt werden kann, da das Bundesverfassungsgericht keine konkreten und genauen Kriterien fu¨r die Rahmenbedingungen vorgegeben hat. U¨ber dieses rechtswissenschaftlich und rechtspolitisch wichtiges Thema muss in der Zukunft weiter geforscht werden.
