  • Experiments on sweet sorghum(sorgo) with different population per unit area were conducted from 1966 to 1968 for the first time in Korea. By increasing plant population stalk weight, refinable sugar and seed weight per plot were increased, but stalk weight per plant, brix percentage, sugar content, stem diameter and 1, 000 seed weight were decreased. Plant height, maturity and lodging were not affected by the treatments. The result obtained has suggested that the effects of plant spacing within row on the characteristics of plant growth and on yields were greater than those of row width. Negative correlations existed between sugar content and sugar yield, and seed weight per plant and seed yield. The optimal plant population in this study ranged from 16, 700 to 22, 200 plants per 10a, row width of 60cm and plant spacing in row of 15 to 20cm resulted in the highest sugar and seed.

  • Based on the constituent analysis of sediments near Dok Island, the origin and sedimentary facies were Investigated. The sediments are mainly from originated from volcanic and volcaniclastic rock fragments derived from Dok Island and carbonate sediments formed by a variety of shallow-dwelling organisms that secreted calcareous skeletons. Carbonate producers include mollusks (bivalves and gastropods), encrusting & branching bryozoans, encrusting & segmented red algae, worm tubes, barnacles, diatoms, sponge spicules and echinoderm fragments. The distribution and relative amount of these constituents are basically dependent upon water depth and grain size even though local variations can be observed within the same depth interval. Five sedimentary facies can be divided: nearshore facies (<20 m), neritic facies ($20{\sim}100m$), upper transitional facies ($100{\sim}200m$), lower transitional facies ($200{\sim}700m$), and hemipelagic facies (>700 m). The sediments that were sampled below the water depth of 2,000 m still contain a significant amount of carbonates (ca. $10{\sim}20%$), implying that the carbonate compensation depth in the East Sea may well exceed this water depth.

  • 리더십에 관한 연구는 리더십 특성요인연구, 리더십 contingency 연구, 특성이론적 접근, 행동적 접근, 상황이론적 접근 등이 있으나, 이러한 접근방법이 언제나 긍정적인 리더십을 유발하는 것은 아닌 것으로 나타나고 있다. 따라서, 긍정적이고 일관된 리더십을 만들어 내기 위해서는 리더십에 대한 새로운 접근이 요청된다. 리더십에 대한 연구는 매우 다양하게 나타나고 있으나, 문헌연구에서 볼 때 리더십은 파워라는 공통 요소를 가지고 있다. 파워는 사람으로 하여금 목적지향적인 행동을 유발하는 능력이며, 문헌에 나타난 리더십의 개념은 조직구성원으로 하여금 목적지향적인 행동을 하게하는 능력이다. 따라서, 리더십은 권력의 한 유형으로 볼 수 있다. 그러므로, 본 연구에서는 리더십을 power process에 기초한 권력순환적 관점에서 연구하고자 한다. Power process는 권력요소, 가치, 욕구, 환경, 관계의 다섯 가지 권력결정요소들의 상호작용 과정이다. 이러한 상호작용을 통해서 power process는 권력의 원천을 창출하는데 이 원천에 의한 권력행사는 긍정적인 결과를 유발한다(이경환, 2001). 앞에서 지적한 바와 같이 리더십은 권력의 한 유형이므로, power process에 의한 리더십 행사를 실증연구를 함으로서 지식경영시스템 구축을 위한 요인을 제시하고자 한다. 본 실증적 연구에서 리더는 자신의 권력요소(타고난 능력, 소질, 경험 등=경영자특성)와 욕구, 가치(경영철학) 관계성 및 환경과 같은 파워결정요소(리더십 결정요소)의 상호작용을 통해 자신의 리더십 원천을 창출할 때 즉, power process를 통해 리더십을 행사할 때 이러한 리더십은 경영성과에 긍정적인 결과를 유발하는 것으로 나타났다. 그러므로, 리더십 성과 향상을 위한 지식경영정보시스템은 파워결정요소적 측면에서 고려되어야 할 것이다. 모델과 독립성 모델에서는 시스템 등급에 영향을 준다. 향후에는 더욱 더 다양한 상호의존 모델들이 정량화될 필요성이 있다고 본다. 진행하였다. 줄여서 보다 더 정확하고, 지능적인 규칙구성요소 추출 방법론을 제시하고 구현하여 지식관리자의 규칙습득에 대한 부담을 줄여 주고자 한다. 도움을 받을 수 있게 되었다.을 거치도록 되어있다. 교통주제도는 국가의 교통정책결정과 관련분야의 기초자료로서 다양하게 활용되고 있으며, 특히 ITS 노드/링크 기본지도로 활용되는 등 교통 분야의 중요한 지리정보로서 구축되고 있다..20{\pm}0.37L$, 72시간에 $1.33{\pm}0.33L$로 유의한 차이를 보였으므로(F=6.153, P=0.004), 술 후 폐환기능 회복에 효과가 있다. 4) 실험군과 대조군의 수술 후 노력성 폐활량은 수술 후 72시간에서 실험군이 $1.90{\pm}0.61L$, 대조군이 $1.51{\pm}0.38L$로 유의한 차이를 보였다(t=2.620, P=0.013). 5) 실험군과 대조군의 수술 후 일초 노력성 호기량은 수술 후 24시간에서 $1.33{\pm}0.56L,\;1.00{\ge}0.28L$로 유의한 차이를 보였고(t=2.530, P=0.017), 술 후 72시간에서 $1.72{\pm}0.65L,\;1.33{\pm}0.3L$로 유의한 차이를 보였다(t=2.540, P=0.016). 6) 대상자의 술 후 폐환기능에 영향을 미치는 요인은 성별로 나타났다. 이에 따른 폐환기능의 차이를 보면, 실험군의 술 후 노력성 폐활량이 48시간에 남자($1.78{\pm}0.61L$)가 여자($1.27{\pm}0.45L$)보다 더 높게 나타났으며 (t=2.170, P=0.042),

  • The purpose of this study is to identify the characteristics of school library services using the RGT (repertory grid technique), and to examine whether there are differences in the perceptions and internal experiences of school library services between human resources (librarian teachers, subject teachers, and librarians). I used indicators such as element intensity, construct extremity, discrepant constructs, and implicative dilemmas to analyze the characteristics of school library services. The elements of the repertory grid were set to 9, and 14 constructs were set through focus group interviews with 3 librarian-teachers. The GRIDCOR 6.0, which can be accessed online, was used to complete the repertory grid for 30 graduate students of the College of Education, and 6 of them were selected and analyzed, considering the demographic characteristics. From the perspective of element intensity, it was found that the following school library services are important and influential: resource management, teacher-librarian collaboration, and reading and information counseling services. The clarity of one's role, the actual performance, and self-regulatory ability were ranked high from the perspective of constructs intensity.

  • In this study, the content and level of the elements of Computational Thinking in the Software Education area of elementary practical textbooks were analyzed, and also the computing ratio for each textbook learning activity was analyzed. The elements of Computational Thinking were defined based on the components and definitions of Computational Thinking skills suggested by the Ministry of Education. The contents of Software Education area in practical arts textbooks published by six publishers were analyzed. As a result of analyzing the elements of Computational Thinking for each textbook according to the achievement criteria, there was a difference in whether sub-elements of Computational Thinking were included for each textbook. Second, as a result of analyzing the level of Computing of learning content, the proportion of textbooks presenting Abstract activities connected to Computing was relatively low. When the curriculum is reorganized or the textbook is revised in the future, it is necessary to complement the elements of Computational Thinking in a balanced way, and to include general Abstraction activities and Abstraction activities that can lead to Automation.

  • This field experiment was undertaken to assess the effects of three levels of inclination ($10^{\circ},\;20^{\circ},\;and\;30^{\circ}$) and four rates of $N-P_2O_2-K_2O$ (O-O-O, 14-10-20, 28-25-25, and 42-40-40kg/10a) on establishment, forage yield and quality and botanical composition of new established mixed grass-clover sward. This first part is concerned with the forage yield, yield component and botanical composition. The results obtained after a two-year experiment are summarized as follows: 1. Dry matter yields of mixed grass-clover sward were greatly decreased by increasing the inclination grade of hilly pasture, whereas it of weeds was not significantly influenced. Comparing with weeds, the establishment of introduced pastures was relatively low with increasing the grade of inclination. 2. By increasing the NPK rate, the yields of grasses and mixed forages and the rate of introduced pastures were greatly increased at all grades of inclination, whereas the change in the weed yield was not significant. 3. There were the differenced in the forage yield and yield component, and efficiency of fertilizers by the grade of inclination, which indicated the necessity of different management on the selection of suitable grass species, seeding rate, amount of fertilizer application, and the methods of grassland establishment, management and utilization.

  • The purpose of this study was to investigate the effects of the constructivist instructional model on the acquisition of atmospheric pressure conceptions and learning motivation. The step of constructivist instruction was prediction and explanation-experiment and observation-discussion-application. The control group consisted of two classes of students who participated in the teacher-centered instruction. The experimental group consisted of two classes of students who participated in the constructivist instruction. To examine students' preconceptions before the instructions, a preconceptions test was administered. After the instructions, students' acquisition of atmospheric pressure conceptions and learning motivation were measured with a researcher-made post-conceptions test and The Course Interest Survey. The results from this study were as follows: First, the constructivist instruction is more effective method in acquisition of atmospheric pressure conceptions and learning motivation than the teacher-centered instruction. Therefore, in order to increase the acquisition of science conceptions and to decrease the science misconceptions, we need to use the constructivist instructional model which make learners self check their own preconceptions of science. Second, the constructivist instruction is more effective than teacher-centered instruction in three elements of learning motivation. So, we need to develop the effective ARCS(attention, relevance, confidence, satisfaction) strategies in order to use the constructivist instructional model and to verify it's effectiveness. Third, to improve teaching and learning methods, educational researchers should carry out studies using many points of view than studies biased constructivism or objectivism. In this respect, we need to contrive how to integrate constructive view points and objective view points.

  • The purpose of this study is to develop and implement an alternative elementary science curriculum to enhance creative problem solving abilities. The curriculum consisting of three main elements was developed. The three elements are content knowledge, process knowledge and creative thinking skills. The curriculum was validated by more than 10 science educators, scientists, and curriculum specialists. In order to implement the curriculum, three lessons for 5th grade were developed and taught by a problem-based-learning(PBL) method in an experimental group during the second semester. For the comparison group the ordinary lesson based on the 6th national science curriculum was taught by the same science teacher during the same period. Performance assessment was developed and used for the pre and post test. Two-way ANOVA, and T-test were used to check whether there are any significant differences between the gains of scores(pre-post test) of the two groups. The results of the test showed that the experimental group increased significantly in the total creative thinking problem solving skills, but the comparision group did not.

  • 국민복지에 대한 사회적 관심과 복지실현의 핵심 요소로 도서관이 인식되면서 공공도서관의 수가 2000년대 들어 급격히 증가하고 있다. 1980년에 79개관에 불과했던 전국 공공도서관이 2013년 말 기준으로 885개관에 이르고 있으며, 공공도서관의 효율적 공간구성에 대한 이용자 요구가 증대되고 있다. 특히 이용자의 요구에 부응하기 위한 디지털열람실과 문화교육실의 증가는 2000년 전 후의 변화에 따른 시사점으로 나타나고 있으며, 기존 공간구성 비율에서 벗어나 시대에 적합한 도서관 공간계획이 필요한 시점이다. 이 연구는 1980~1990년대 준공된 공공도서관과 2000년 이후 설립된 공공도서관을 중심으로 시대별 공공도서관의 공간구성 형태를 상호 비교분석하였다. 장서보존과 열람 기능이 강조되었던 1980~1990년대와 이용자의 측면을 고려하여 문화영역 기능이 확대된 2000년대 이후 공공도서관의 소요시설별 면적비율의 차이를 살펴봄으로써 시대요구와 부합할 수 있는 면적기준을 제시하였다.

  • This study aims to explore concepts of public interest and universal service which have been essential ideologies and policy goals, but which have been a the state of conceptual chaos so far. It sheds light upon three aspects : (1) the origins of public interest and universal service, (2) conceptual components of public interest and universal service, and (3) the implementation of public interest and universal service ideologies into policy. As a result of this analysis, it was found, firstly, that public interest of broadcasting originated from western countries, was rooted in the United States, and then spread all over the world later. After universal service was begun in the United States, it became a key ideology of information and telecommunication in European countries and other countries as well. Secondly, when examining the conceptual components, more differences were found than commonalities between these two concepts. The most conspicuous common point was universalism The concept of public interest includes not only universal service, but also connotes other components such as independence, diversity, quality, and locality which are related to content. Thirdly, when these two ideologies are implemented into policy, there Is a contrast. This study shows that the public interest ideology was realized into regulatory policies, while the universal service ideology was realized into supportive policies. In conclusion, this paper suggests more exact usage academically, showing the differences between the two concepts. This paper recommends an enforced legal duty of broadcasters to provide universal service when the current broadcasting law is revised.
