This article is to analyse the economic efficiency of capital market, which plays a role of resource allocation in terms of financial claims such as stock and bond. It provides various contributions to the welfare theoretical aspects of modern capital market theory. The key feature that distinguishes the theory described here from traditional welfare theory is the presence of uncertainty. Securities has time dimensions and the state and outcome of the future are really uncertain. This problem resulting from this uncertainty can be solved by complete market, but it has a weak power to explain real stock market. Capital Market is faced with the uncertainity because it is a kind of incomplete market. Individuals and firms in capital market made their consumption-investment decision by their own criteria, i. e. the maximization of expected utility form intertemporal consumption and the maximization of the market value of firm. We noted that allocative decisions that had to be made in the economy could be naturally subdivided into two groups. One set of decisions concerned the allocation of first-period resources among consumption $C_i$, investment in risky firms $I_j$, and riskless investment M. The other decisions concern the distribution among individuals of income available in the second period $Y_i(\theta)$. Corresponing to this grouping, the theoretical analysis of efficiency has also been dichotomized. The optimality of the distribution of output in the second period is distributive efficiency" and the optimality of the allocation of first-period resources is 'the efficiency of investment'. We have found in the distributive efficiency that the conditions for attainability is the same as the conditions for market optimality. The necessary and sufficient conditions for attainability or market optimality is that (1) all utility functions are such that -$\frac{{U_i}^'(Y_i)}{{U_i}^"(Y_i)}={\mu}_i+{\lambda}Y_i$-linear risk tolerance function where the coefficients ${\mu}_i$ and $\lambda$ are independent of $Y_i$, and (2) there are homogeneous expectations, i. e. ${\Large f}_i(\theta)={\Large f}(\theta)$ for every i. On the other hand, the efficiency of investment has disagreement about optimal investment level. The investment level for market rule will not generally lead to Pareto-optimal allocation of investment. This suboptimality is caused by (1)the difference of Diamond's decomposable production function and mean-variance valuation model and (2) the selection of exelusive investment or competitive investment. In conclusion, this article has made an analysis of conditions and processes of Pareto-optimal allocation of resources in capital marker and tried to connect with significant issues in modern finance.

The most widely used data mining technique for big data analysis is to generate meaningful association rules. This method has been used to find the relationship between set of items based on the association criteria such as support, confidence, lift, etc. Among them, confidence is the most frequently used, but it has the drawback that we can not know the direction of association by it. The attributably pure confidence was developed to compensate for this drawback, but the value was changed by the position of two item sets. In this paper, we propose four symmetrically and attributably pure confidence measures to compensate the shortcomings of confidence and the attributably pure confidence. And then we prove three conditions of interestingness measure by Piatetsky-Shapiro, and comparative studies with confidence, attributably pure confidence, and four symmetrically and attributably pure confidence measures are shown by numerical examples. The results show that the symmetrically and attributably pure confidence measures are better than confidence and the attributably pure confidence. Also the measure NSAPis found to be the best among these four symmetrically and attributably pure confidence measures.

Architecture framework (AF) is a guideline to define components needed to develop and operate enterprise architecture (EA), and to define relationships among the components. There are many architecture frameworks to operate EA of governments and businesses such as Zachman framework, DoDAF, TOGAF, FEAF, and TEAF. DoDAF is the most representative AF to support the development of the EA in the military domain. DoDAF is composed of eight viewpoints and 40 views that are affiliated with the viewpoints. To develop an AF for a specific goal, system architects decide a set of views. Furthermore, they determine data that are needed for a view modeling. However, views and data in DoDAF are structurally inter-related explicitly and/or implicitly. So, developing an AF for a specific goal is going to be a project to be carried out over a long haul. To reduce the burden of its development, in this paper, we develop ONT-SAF (Ontology for DoDAF) that can infer inter-relationships like referential and transitive relationships and the sequences among the views. Furthermore, to promote reusability and consistency of the views and the data within an AF, we adopt the view-data separation strategy. ONT-DAT contains classes like 'viewpoint', 'view', 'data', 'expression method', and 'reference model', and 11 properties including 'hasView.' To prove the effectiveness of ONT-SAF, we perform a case study.

Several algorithms have been developed to detect AFIB(Atrial Fibrillation) which either rely on the linear and frequency analysis. But they are more complex than time time domain algorithm and difficult to get the consistent rule of irregular RR interval rhythm. In this study, we propose algorithm for optimal value detection of irregular RR interval for AFIB classification based on linear analysis. For this purpose, we detected R wave, RR interval, from noise-free ECG signal through the preprocessing process and subtractive operation method. Also, we set scope for segment length and detected optimal value and then classified AFIB in realtime through liniar analysis such as absolute deviation and absolute difference. The performance of proposed algorithm for AFIB classification is evaluated by using MIT-BIH arrhythmia and AFIB database. The optimal value indicate ${\alpha}=0.75$, ${\beta}=1.4$, ${\gamma}=300ms$ in AFIB classification.

In this paper, a new codebook design algorithm is proposed. It uses a DCT map based on two-dimensional discrete cosine of transform (2D DCT) and finite state vector quantizer (FSVQ) when the vector quantizer is designed for image transmission. We make the map by dividing input image according to edge quantity, then by the map, the significant features of training image are extracted by using the 2D DCT. A master codebook of FSVQ is generated by partitioning the training set using binary tree based on tree-structure. The state codebook is constructed from the master codebook, and then the index of input image is searched at not master codebook but state codebook. And, because the coding of index is important part for high speed digital transmission, it converts fixed length codes to variable length codes in terms of entropy coding rule. The huffman coding assigns transmission codes to codes of codebook. This paper proposes single-side growing huffman tree to speed up huffman code generation process of huffman tree. Compared with the pairwise nearest neighbor (PNN) and classified VQ (CVQ) algorithm, about Einstein and Bridge image, the new algorithm shows better picture quality with 2.04 dB and 2.48 dB differences as to PNN, 1.75 dB and 0.99 dB differences as to CVQ respectively.

This article is aimed at understanding the political narratives represented in the National Museum of Indonesia. Starting initially as a colonial museum, the National Museum of Indonesia functioned as a useful tool for the Dutch colonial force to fuel its imaginations of the colonial territory and the people within it. The Dutch used the cultural display to advertize its benevolent colonial rule. All the while, the museum also inevitably reflected orientalism on the people and the culture of the colony. The republic of Indonesia inherited the colonial museum's practices and its display patterns. The business surrounding the museum also played a key role in the newly-born nation-state laying out a future for its redefined territory and people. Thus, what the colonial force imagined for the colonial territory through the study of museum displays was rather directly transferred to the republic without serious consideration of the decolonization process. Four main characteristics have been seen in the museum displays. The first is an emphasis on the glorious Hindu-Buddha history, from which numerous temples, statues, and jewelry have been found. Secondly, the Islamic period, which spanned between the Hindu-Buddha times to the colonial era, has almost completely been eliminated from the display. Third, the colonial era has been depicted as the time of Europe's exportation of scientific tools and adaption of sophisticated living patterns. Fourth, the images of ethnic groups were represented as being stagnant without reflecting any challenges and responses that these groups had faced throughout history. Looking at these display patterns, it can be concluded that all the dynamic internal developments and anti-colonial resistance that took place during the Islamic and Colonial Era have simply not been represented in the museum display. These display patterns do not reflect the real history or culture of the archipelago. Two considerations are thought to have influenced the neglecting of social realities in the display. The first of which is the Dutch's and Republic's apprehension over the possible political upheaval by the Islamic forces. Yet, more fundamentally, cultural displays themselves are distinct from historical education in that the former pays more attention to business ideas with an aim to attract tourists rather than to project objective historical knowledge. Thus, in cultural displays, objects which work to stimulate fantasies and spur curiosity on archipelagic culture tend to be selected and emphasized. In this process, historical objectivity is sometimes considered less vital. Cultural displays are set up to create more appealing narratives for viewers. Therefore, if a narrative loses its luster, it will be replaced by another flashy and newly-resurrected memory. This fact reveals that museums, as transmitters of historical knowledge, have a certain degree of limitation in playing their role.

A reading aloud performance is an activity in which the actors convey the meaning of the play to the audience through reading the play without memorizing the play. Although this term has been used for a long time, it can be said in the early 2000s that Korea began to pay attention to reading aloud performance in the cultural world. As the theater education is strengthened in the 2015 revision curriculum, interest in this "reading aloud performance" is also growing. In this article, we analyzed the reading aloud performance of the 8th contemporary Japanese drama '2018' in order to utilize the reading aloud performance in the educational field and to utilize it in the lecture of the children education. There are two types of rehearsals for the actors on stage: 'Reading by watching drama', 'Playing by memorizing drama', and 'Mixing two types'. In the end, the key is that there is no set rule for the type of reading aloud performance. It's not trouble to see or not to see the play. It is not necessary to have a stereotype that you should do a proper reading aloud performance in consideration of your situation, but that you should do this. If children understand the concept of read aloud performance in a flexible way, the educational effect will be greater. Based on this analysis, we suggested 'not sticking to the form of reading aloud performance' and 'choosing various types of reading aloud performance' as a criterion for applying to the education field for children. In addition, the sub-criteria required for selecting 'various types of lecture performances' include' selecting a specific scene in the content of the play ',' considering the level or situation of the student ',' not hesitating to make a new type of lecture performance '. I hope that this article will be a stepping stone to revitalize the discussion in the educational world where discussion on the performance of reading aloud is requested, and to solve the problem of lack of educational design due to lack of theory.

After inspecting ground surface or excavating cultural heritage site, the government can take measures for the preservation of buried cultural heritage based on the related law. It means that the provisions complement the limitation of current cultural heritage management system by extending the scope of cultural heritage to be preserved. But we neither have set any matters about implementing the measures for preservation of the buried cultural heritage, nor manage the heritage and its surroundings after implementing the measures. Due to these insufficiency of the law, there arise several problems in the field. For example, the measures for preservation are not complete, or preserved cultural heritage is damaged due to inappropriate management. We have to resolve the problems in order to accomplish the original purpose of taking measures for preservation of the heritage. First, it is necessary to make sure of the legal status of preserved buried cultural heritage, to establish the standards to decide whether to preserve it or not. We need to have regulations by law or internal rule on the daily management, who should manage it, what and how the manager should manage. It is also important for local residents to take an active part in preserving and utilizing the cultural heritage as the owner. Through building up the foundation mentioned above, the meaning and value of preserved buried cultural heritage can be expanded widely.

Lee Ik(李瀷) had put emphasis on the achievements by self-regulated academic learning through doubts, and at the same time that it was all-embracing. His academic attitude had set an example among the members of Seongho school(星湖學派), and his disciples had strived to emulate his style. The greatness of Seongho(星湖)'s study had been revealed by development of Seongho school(星湖學派) right after his death. He had argued that the six strokes of I-Ching should be read having it divided into inward and outward divine signs. He had stated his view clearly that the divine signs ranging from one stroke to six strokes were not connected, same as Shao yong(邵雍)'s method, but, the three strokes of inward divine sign as well as the three strokes of outward divine signs were independent from each other. Seongho(星湖) also had raised many questions about Shifa(筮法), and Bianyao(變爻) and Zhuzi(朱子)'s Shifa(筮法), or Yixueqimeng("易學啓蒙") "Kaobianzhan("考變占")". In view of the Shifa(筮法), Seongho(星湖) had helped Dasan(茶山) to present 'Shiguafa(蓍卦法)' by proposing different divination rule from Zhuzi(朱子)'s Method of Divination by Shiyi("筮儀"). Seongho(星湖) had not professed something significantly different from Zhuzi(朱子) in his I-xue. His study on I-xue had been accomplished under his goal of achievements by self-regulated academic learning through doubts. "Shiguakao("蓍卦攷")" is also same. I-xue of Seongho(星湖) had made a great contribution to form Dasan(茶山)'s I-xue in the later years.

The moral categories in the Mengzi have a close affinity with those of Kongzi. Mengzi fostered the Kongzi's teaching on virtuous rule and moral government, and taught benevolent government based on the virtue of benevolence. Mengzi set up a basis for Confucian teaching on human nature, and his teaching of the essential goodness of human nature has been accepted by most Confucian intellectuals. This study explores the Mengzi's teaching of moral education focussing on his instructional method to expand the goodness of human nature. Instructional method refers to educator-centered transmission of values, and it concerns mainly on how to deliver the educational goal and content meaningfully to the educatee. The main concerns of Mengzi's instructional method are teaching-standard setup, delivery of lecture key points, understanding of students' talent and situation, and encouragement of students' initiative. These points are all based on Mengzi's assertion of good human nature, and aim at forming a ideal personality. Confucian ideas of education lie in raising the well-rounded person through moral education. The well-rounded person can be characterized by noble men and sages with benevolence and righteousness. This means that the ultimate goal of well-rounded education is to lead people to attain the sublime moral stage through education.
