Manganese-doped H-SAPO-34 samples were prepared by an ion-exchanged reaction between H-SAPO-34 and paramagnetic Mn(II) species in methanol media and characterized by ESR and Electron Spin-Echo Modulation(ESEM) studies. In the hydrated (W)MnH-SAPO-34 measured in water, the Mn(II) ion was octahedrally coordinated with four framework oxygens and two water molecules at a displaced site IV of the eight membered ring window in the ellipsoidal cavity, while the Mn(II) ion was octahedrally coordinated to three framework oxygens and three water molecules at a displaced site I’ of the six membered ring window in the ellipsoidal cavity in hydrated(M)MnH-SAPO-34 measured in methanol. The similar result was found in the experiments with methanol adsorbents except ethanol. 영어논문
On a newly reclamed soil an experiment was carried out to find out the proper measure of amount of phosphorus fertilizer and application method for improved of yield in Honam area. Results are summarized as follows; 1. The yield was high in whole layer placement of phosphorus fertilizer and low in deep placement in application methods. 2. In the amount of phosphorus fertilizer, broadcasting with 15% of phosphate fixation coefficient, whole layer and deep placement of fertilizer with 10% of phosphate fixation coefficient were maximum yield respectively. 3. In a large quantity of application phosphate, stem diameter of soybean was thicker and blanch and pod number were increase more than the another plot. 4. Application of phosphorus fertilizer 9 ppm of phosphate before experiment become 48 to 123 ppm after and contents of base inclined high. 5. In plant analysis, there was positive correlation between the yield of soybean and the content of phosphate in plant, and a large quantity of phosphate will be absorbed into the plant and utilized it at generative growth after blooming stage.
For the increase of soybean yield in newly reclaimed area, this experiment was carried out in Kimje (plain area) and Jinan (hilly area) to determine the effect of nitrogen topdressing on agronomic characters. grain yields, protein and oil contents of soybean in 1982~1983. The results obtained were summarized as follows; 1. During growing period, average mean temperatures were similar, but amounts of rainfall and sunshine hours were smaller in Jinan than in Kirn je. 2. Applications of sufficient amounts of phosphates and lime increased available P20S and exchangeable Ca contents on both soils to optimum levels within one year after reclamation. 3. Days required for flowering (days from sowing to flowering) were shortened as sowing dates were later. 4. Nitrogen topdressing at flowering shortened the length of branches, but increased number of branches per plant, thus preventing over-thriving and lodging as compared with basal fertilization. 5. Nitrogen topdressing at flowering increased number of pods per plant and weight of 100 seeds. 6. Significant positive correlation were observed between grain yield and stem length, number of branches per plant, number of pods per plant, and weight of dry matter. 7. A significant negative correlation was obtained between grain yield without topdressing and yield increasing index by topdressing. The result indicates that nitrigen topdressing may be very effective practice III newly reclaimed area. 8. Soybean seeds produed in Jinan had higher protein contents than there of in Kimje. Higher protein contents in grains were noted with nitr ogen topdressing than without topdressing (only basal fertilization). Tendency of oil content was just opposite to above results of protein content. The protein content was significantly negative correlates with oil contents, regardless of area and varieties. 9. Total nitrogen content by Danyeobkong(medium type) plants was increased continuously until maturing stage, but that by Kwangkyo (limited type) plants showed the peak at 30 days after flowering. Total nitrogen content by plants at 30 days after flowering was significantly correlated with grain yield of soybeans. 10. The order of distribution ratio among plant parts in nitrogen content at maturing stage was mainstem < branch < pod < seed. The distribution ratio in seed was highest in the plants that receiving nitrogen topdressed at flowering. 11. Application of 8kg/l0a nitrogen as only basal fertilization inhibited formation of nodules in soybean roots, and nitrogen topdressing tended to decrease their sizes. 12. Topdressing of 4kg/10a nitrogen at flowering stage increased grain yields by 23-36% and 18-27% in Danyeobkong, and by 15-56% and 20-28% in Kwangkyo , III Kimje and Jinan respectively.
Researches on military weapons are actively studied to improve national defense power of each country. The military weapon system is being used not only as a weapon but also as a reconnaissance and surveillance device for places where it is difficult for people to access. If such a weapon system becomes an object of attack, military data that is important to national security can be leaked. Furthermore, if a device is taken, it can be used as a terrorist tool to threaten its own country. So, security of military devices is necessarily required. In order to enhance the security of a weapon system such as drone, it is necessary to form a chain of trust(CoT) that gives trustworthiness to the overall process of the system from the power on until application is executed. In this paper, by analyzing the trusted computing-based boot technology, we derive trusted boot technology components and classify them based on hardware dependence/independence. We expect our classification of hardware dependence/independence to be applied to the trusted boot technology of our self-development ultra- precision weapon system to improve the defense capability in our military. 세계으로 국방력 향상을 해 정무기체계에 한 연구가 활발히 진행되고 있다. 정무기체계는 무기로 사용될 뿐만 아니라 사람이 근하기 힘든 장소의 정찰 감시 역할도 수행하기 때문에 그 활용성이 차 확장되고 있다. 이러한 무기체계가 공격의 상이 될 경우, 국가 안보에 요한 군사 데이터가 유출될 수 있고, 더 나아가 기 기가 탈취될 경우 오히려 자국을 하는 테러 도구로 사용될 수 있기 때문에 이와 같은 을 방지하기 해서는 무기 체계에 한 보안이 매우 요하다. 이러한 무기체계의 보안을 유지하기 해서는 원이 인가된 시부터 응 용로그램이 실행되기까지 시스템 운용의 반인 모든 과정에 신뢰성을 부여하는 신뢰체인을 형성하는 것이 필 요하다. 따라서 본 논문에서는 신뢰성 부 기술 분석을 바탕으로 신뢰성 부 기술을 구성하는 요소 기술들을 도출 하고 하드웨어 종속/독립성을 기으로 분류한다. 본 논문에서 분류한 하드웨어 종속/독립성에 따라 분류한 신뢰성 부 구성 요소를 바탕으로 신뢰성 부 기술을 용하기 해 필요한 최소한의 하드웨어 종속인 구성 요소를 제 시하여 우리 군에서 국방력 향상을 해 자체개발하는 정무기체계 설계에 용될 수 있을 것으로 기된다.
비가츠키이론에 따르면, 놀이가 아동에게 주는 역할과 같이 시뮬레이션은 학습자의 발달을 위한 훌륭한 도구(tool)가 된다. 즉, 시뮬레이션은 학습자에게 사회에서 이용가능한 지식과 기능을 습득시킬 수 있고, 의사 결정을 위해 필요한 정보를 수집하고 이를 재구성하도록 유도할 수 있으며, 문제 해결 과정을 통해 잠재적 발달수준(potential development level)을 향상시킬 수 있다. 사회과에서의 의사결정력은 사회적 상황에 대한 올바른 이해와 문제 파악이 전제되어야 하는데, 시뮬레이션은 학습자에게 사회적 상황을 체험할 수 있는 기회를 제공한다. 그러므로, 사회과 교수-학습에서 시뮬레이션의 역할은 학습자가 보다 진전된 다른 상황이나 실제상황에 직면했을 때, 그 상황에서 발생하는 문제를 해결할 수 있는 의사결정력을 향상시키는 '받침대(scaffold)'로써 기능하게 된다. 비가츠키이론을 바탕으로 시뮬레이션프로그램의 개발 방향을 제시하면 다음과 같다. 첫째, 제시하는 개념과 상황은 학습자의 잠재적 발달수준에 상응하여 다른 난이도를 가지고 단계적으로 제공되어야 한다. 둘째, 제시한 문제를 해결하는 과정에서 협동학습을 통해 타자와의 상호작용이 이루어지도록 대화식으로 설계해야 한다. 셋째, 시각적 화상들을 다양하게 제시하고 의사결정 사례들의 획일적이 되지 않도록 제공해야 한다. 넷째, 학습자의 의사결정력을 평가하는 수행평가과정이 포함되도록 제작해야 한다. According to Vygotsky's theory, simulation is an effective tool on learners, just as the role of play in childhood. That is to say, simulation can help learners acquire some useful knowledge and skills in society, and promote learner to collect and reconstruct informations for decision making, and raise the potential development level. Decision making ability in social studies is premised on proper understanding problems in social context, and simulation gives learners an opportunity of undergoing social situation. Therefore, simulation in social studies education, when learners are faced with more advanced situation or actual one, is functioned as a scaffold for decision making to solve some problems in the situation. Based on Vygotskian theory, several suggestions could be made in programming simulation. First, simulation program can give learners, different levels of concepts and situations corresponding to learner's potential development level. Second, simulation program must be designed dialogically for the cooperation learning, in which interactions are made with others during the decision making process to solve problems. Third, simulation program can suggest various visual displays and examples of decision making. Fourth, simulation program must include the performance assessment procedure which evaluates learner's decision making ability.
