The Beopmaru, Supreme Court Library of Korea, the national library of the judiciary, is the only one that can help reduce the justice gap and increase access to justice by allowing the general public and legal experts to read and circulate. Accordingly, this study identified user satisfaction with the Beopmaru public service through surveys and interviews and derived ways to improve the service. User satisfaction was in the following order out of 5 points: response of librarian 4.62 points, facility management 4.48 points, and cultural programs such as events and lectures 4.33 points. Satisfaction with collection composition was the lowest at 3.97 points. This appears to be because collection composition is where legal expertise has the greatest impact on satisfaction. As satisfaction with the collection composition was the lowest, collection expansion was the highest at 44%(114 people) as a service that Beopmaru needs to strengthen in the future, and a balanced collection of books according to the user base is needed in the future. Based on this, improvement measures were proposed to include dualizing the Beopmaru reading space and services for the general public and legal experts, strengthening its identity as a legal library, improving the system, and strengthening publicity and response of librarian. If the Beopmaru public service is successfully established through continuous research in the library and information community, it will be possible to improve the service quality of the law library industry as a whole, including law libraries, and increase user satisfaction.

In this paper, a method for constructing Galois switching functions is presented. Single variable Galois switching function is constructed at fi tost by developing Lagrange's Interpolating formula into polynomial forms and then the constructing theory for two variables is driveloped. With these developed theory, multitle-variable Galois switching functions are constructed. Some examples for illustrating the theory are adopted from the existing papers and the results quite agree with the ones in the other papers.

동적 공급사슬망은 복잡하고 다양한 이해관계를 가진 기업들로 구성되어 있다. 다수의 구매자로부터 주문 의뢰가 동시다발적으로 발생하므로 하위 구성원들은 경쟁적 관계에 놓이게 된다. 그러므로 최적의 공급사슬구성을 위해서는 수평적 경쟁 관계를 고려하여 구성주체들간의 협력관계를 통해 이를 해결하여야 한다. 지금까지의 스케줄링 문제에서는 상위의 구성원이 하위 구성원들을 일방적으로 선택하는 의사결정이 이루어졌으나 본 문제에서는 구성원간의 협력관계에서 에이전트를 통한 다자간 협상을 통해 공급사슬 전체의 최적화를 구성하는 방법론을 제시한다. 본 협상방법론은 단일기계에서 상이한 납기일, 조기생산(earliness), 지연생산(tardiness)을 동시에 고려하였으며 전체 공급사슬의 평균절대편차(Mean Absolute Deviation)의 최소화를 목적으로 하고 있다. 본 협상방법론의 효과성을 증명하기 위해 분지한계법(Branch & Bound)과 비교하고, 알고리즘 구현을 통해 구매자 협상방법론의 최적화 여부를 실험을 통해 증명하였다.

소수력 발전은 대체에너지의 일환으로 공해가 없고 작동의 신뢰도가 높아 신재생에너지 연구개발과 관련하여 소수력발전에 대한 관심이 높아지고 있으나, 기존의 대수력용 수차와는 달리 소수력용 수차 및 주변 시스템의 설계법이 근래 확립되어 있지 않다. 본 연구에서는 수차의 크기 및 수차의 잠김 정도가 일정한 유량과 유속에 대하여 수차의 각 운동량, 즉 출력에 미치는 영향에 대하여 분석하고 이를 토대로 수차의 적정 설치기준 및 수차를 제어하기 위한 제어용 소프트웨어를 마련하기 위하여 실험 환경을 구성하고, 구성된 실험 환경에서 자료 취득을 하기 위한 전자 회로 및 소프트웨어를 구성하고, 구성된 장치와 환경에서 취득한 자료가 유효함을 확인하였다.

장내세균의 구성과 각종 질환의 상관관계에 대한 연구가 활발히 수행되고 있다. 대장관련 질환 뿐 아니라, 당뇨, 비만 등 대사성 질환, 심지어 정신질환에까지 장내세균 구성의 영향이 미치는 것으로 밝혀졌다. 이에 다양한 천연 소재를 활용하여 각종 동물질환모델에서 생리활성을 검토할 때, 장내세균의 구성을 분석하여 그 상관관계를 밝힐 필요가 있다. 장내세균의 구성에 따라 질환의 양상이 달라질 수 있으며, 치료에 영향을 줄 수 있다. 동물실험을 수행할 때에도 실험동물 간 장내세균의 구성이 다르면 질환의 유도 또는 천연소재에 의한 치료 패턴이 달라질 수 있음을 가정하여 본 연구를 수행하였다. 본 연구에서는 EtOH와 LPS를 이용하여 간장해 동물모델을 구축하고, 장내세균 구성을 T-RFLP법으로 분석하여 그 상관관계를 검토하였고, tracheloside 등의 천연물을 투여함으로써 성분의 대사 패턴을 확인하였다. 이 결과는 천연소재의 간장해 개선 연구를 수행하기 위한 기초 결과로 활용될 수 있다.

In odor to select optimum extraction methods of volatile compounds in beef extract powder(BEP) as basic data for the development of a new detection method of irradiated BEP, four extraction methods, such as solid phase microextraction with polar fiber(S-PD) and non-polar fiber(S-CD), purge and trap(P&T) and liquid liquid continuous extraction(LLCE) methods, were tested with gas chromatography/mass spectrometry method. A total of 106 volatile compounds including 22 hydrocarbons, 7 aldehydes, 6 ketones, 13 alcohols, 6 sulfur-containing compounds, 19 nitrogen-containing compounds, 6 aromatic compounds, 17 terpenes, 8 furans and 2 miscellaneous compounds were detected in BEP by four detection methods. The most compounds(62 compounds) were detected by S-PD method, followed by P&T(43), LLCE(38) and S-CD method(30). Among these methods, S-PD and P&T methods showed a complementary interrelationship to detect volatile compounds as S-PD method showed high detectabiltiy to all compound groups except hydrocarbons and ketones, which had high volatility and low molecular weight(less than RI 1200), but P&T method showed the contrary pattern to that of S-PD method. Moreover, the most of volatile compounds detected by S-CD and LLCE methods were also detectable by S-PD or/and P&T methods. Therefore, the simultaneous application of S-PD and P&T methods were selected as the optimum volatile extraction methods of BEP.

In this study, we investigated the middle school students' processes of scientific graph construction from the perspective of the problem solving process. Ten 9th graders participated in this study. They constructed a scientific graph based on pictorial data depicting precipitation reaction. The think-aloud method was used in order to investigate their thinking processes deeply. Their activities were videotaped, and semi-structured interviews were also conducted. The analysis of the results revealed that their processes of scientific graph construction could be classified into four types according to the problem solving strategy and the level of representations utilized. Students using the structural strategy succeeded in constructing scientific graph regardless of the level of representation utilized, by analyzing the data and identifying the trend based on the propositional knowledge about the target concept of the graph. Students of random strategy-higher order representation type were able to succeed in constructing scientific graph by systematically analyzing the characteristics of the data using various representations, and considering the meaning of the graph constructed in terms of the scientific context. On the other hand, students of random strategy-lower order representation type failed to construct correct scientific graph by constructing graph in a way of simply connecting points, and checking the processes of graph construction only without considering the scientific context. On the bases of the results, effective methods for improving students' ability to construct scientific graphs are discussed.

From 2011, newly developed Information textbook will be given to high school students. This research investigates contents of the new Information textbook and attempts to offer improvement of the book, which were compiled according to the 2007 Revised Curriculum. This thesis aims to make a comparative analysis of the contents and structure of six Information textbook which passed the screening. The structures of six textbooks were examined under four sections, which are overall structure, relative importance in the textbook, development method, and evaluation type. Moreover, for analyzing the contents, the research investigated the number of the major concepts that are dealt in the textbooks. The results show that there are too many difficult concepts for high school students and reveals that there are big difference in the contents and construction among textbooks. This research suggests how the textbook should be revised in the light of the contents, construction, terminology, and practical training.

높임법의 최소형 정립은 말본범주의 인지뿐만 아니라, 사전의 어휘항복 설정에 절대적 중요성을 갖는다. 굴곡가지의 높임법 낱덩이, 곧 최소형 인지의 요건은 첫째, 분포상 굴곡가지가 줄기에 직접 통합되어야 한다는 것이며, 둘째, 줄기에 직접 통합되는 요소가 높임법의 의미를 가져야 한다는 것이다. 단순형태소가 줄기에 직접 통합하여 존대의 의미를 가지는 것은 홑최소형이 되고, 다른 것과 의무적으로 통합하여 줄기에 직접 통합되는 것은 겹최소형이다. 의무적인 겹최소형이 다시 독립적으로 설 수 있는 비의무적 요소와 통합하여 새로운 존대의 의미를 생성한다면, 이 또한 겹최소형이 된다. 높임의 최소형은 높임법과 의항법의 이차원의 성격을 띤다. 따라서 높임의 최소형의 전 분포는 높임의 등분과 함께, 의향법 체계에 걸쳐 있다. 최소형은 풀이씨의 종류에 따라 다름도 주의할 일이다. 시상법은 높임법의 구성소일 뿐이며, 또한 그 자체 독립하는 것으로 높임법과 의향법과는 그 차원을 달리한다.
