  • In this paper, we propose an efficient face region detection technique for the content-based video summarization. To segment video, shot changes are detected from a video sequence and key frames are selected from the shots. We select one frame that has the least difference between neighboring frames in each shot. The proposed face detection algorithm detects face region from selected key frames. And then, we provide user with summarized frames included face region that has an important meaning in dramas or movies. Using Bayes classification rule and statistical characteristic of the skin pixels, face regions are detected in the frames. After skin detection, we adopt the projection method to segment an image(frame) into face region and non-face region. The segmented regions are candidates of the face object and they include many false detected regions. So, we design a classifier to minimize false lesion using CART. From SGLD matrices, we extract the textual feature values such as Inertial, Inverse Difference, and Correlation. As a result of our experiment, proposed face detection algorithm shows a good performance for the key frames with a complex and variant background. And our system provides key frames included the face region for user as video summarized information.

  • The objective of the study is to develop a reservoir optimal operation model and to suggest the appropriate amount of additional water supply and optimal operation rule. The model uses multiple objective function and a global search method, SCE-UA method. The objective function is set up to maintain the storage at target level, to satisfy the water demand, and to maximize the hydropower product. To evaluate the model's applicability, the model was applied for allocating the optimal water depending on storage level changes of Seomjin dam. The results comparing optimal operation and historical data showed that hydropower product increased from $-2.29\%$ to $14.51\%$, $-5.94\%$ to $3.98\%$, and $-0.43\%$ to $6.35\%$ with varying target levels in wet, dry, and normal period, respectively. Also, The model was applied for assessing water supply capacity of Seomjin dam to satisfy increasing water demand. The dam was operated by the model on consideration of downstream flow as 0.17, 0.50, 0.70, 1.0, 1.5, and $3.0\;m^3/sec$. The results showed that in case of operating the dam with downstream flow less than $0.70\;m^3/sec$ and with target water level lower than 194.0 m, hydropower product was more than the historical operation data and existing amount of water supply was less influenced.

  • Various studies on program management have been attempted due to recent changes in the environment of the construction market, and the importance of closure phase in each phase of the construction program is increasing. However, the reality is that the related research is insufficient and the field has been managed in a rule of thumb according to individual capabilities. Therefore, in order to successfully close the construction program and enhance satisfaction of stakeholders in the closure phase of the construction program, the key stakeholders were identified using the Power and Interest Matrix. The relative importance of the closure phase process was analyzed using AHP analysis method. It was also verified through on-site surveys and interviews about the proposed importance of the closure stakeholder and the relative importance of the process. It is expected that this study will increase the satisfaction of stakeholders and contribute to a successful closure if the user puts a lot of resources into the process that has a high priority in the closure phase of the construction program proposed in this study.

  • A bond-based peridynamic model has been reported dynamic fracture characteristic of brittle materials through a simple constitutive model. In the model, each bond is assumed to be a simple spring operating independently. As a result, this simple bond interaction modeling restricts the material behavior having a fixed Poisson's ratio of 1/4 and not being capable of expressing shear deformation. We consider a state-based peridynamics as a generalized peridynamic model. Constitutive models in the state-based peridynamics are corresponding to those in continuum theory. In state-based peridynamics, thus, the response of a material particle depends collectively on deformation of all bonds connected to other particles. So, a state-based peridynamic theory can represent the volume and shear changes of the material. In this paper, the perfect plasticity is considered to express plastic deformation of material by the state-based peridynamic constitutive model with perfect plastic flow rule. The elastic-plastic behavior of the material is verified through the stress-strain curves of the flat plate example. Furthermore, we simulate the high-speed impact on 3D granite model with a nonlocal contact modeling. It is observed that the damage patterns obtained by peridynamics are similar to experimental observations.

  • This paper aims at examining the local records management under the influence of the Public Archives Act established in 2009 through a case study of prefectures and large cities with prefectural level dominions in Japan. The records management in local government has been carried out on the basis of 'the document management rule' in administrative agencies without the public archives management law. Modification of laws and ordinances in relation with records and archives management and reorganization of archives are proceeding to realize 'proper records management' in local government. Even if the content and levels are varied due to the situational conditions of local governments, the unitary records management system covering 'current and non-current' records is being adopted through the establishment of records management ordinances. In the process, local archives are pursuing strengthening and extension of their authorities and functions on records management. In addition, it is identified that observation of the provisions of records management ordinance is reinforced with public announcement of retention schedule and operation of public records management committees. These changes in local governments reflect the thought that administrative records are the intellectual property of the public and the intent of the law that accountability for the public should be achieved through the proper records management.

  • This paper is about Zhuzi(朱子) writings entitled Yixueqimeng("易學啓蒙"). There are only four research articles on Yixueqimeng("易學啓蒙"), although it had taken important role in the process of formation of Zhuzi(朱子) study of changes, comparing with 30 different kinds of research on his works after this Yixueqimeng("易學啓蒙"). In line with this, the author intends to make this paper as a full-scale research article on Zhuzi(朱子) work - Yixueqimeng("易學啓蒙"). Zhuzi(朱子) exposes the meaning of the Xiangshuyixue(象數易學), to wit, the emblem and numerology of Emblem and Numerology in interpreting Zhouyi("周易") again by accepting Hetu("河圖") and Luoshu("洛書"). When discussing the Zhouyi("周易"), Yiliyixue(義理易學) had drawn supports from Wangbi(王弼) Deyiwangxianglun(得意忘象論). Likewise, Zhuzi(朱子) tried to ruminate upon the meaning of the Hetu("河圖") and Luoshu("洛書") through the Yixueqimeng("易學啓蒙"). As he interprets all things through Hetu("河圖") and Luoshu("洛書"), these two systems of emblem have become essential. Even in Shifa(筮法), he elicited Dayanzhishu(大衍之數) from Hetu("河圖") and Luoshu("洛書") so that he related the divination rule to Hetu("河圖") and Luoshu("洛書"). By doing so, Zhuzi(朱子) concatenates Dayanzhishu(大衍之數) to Hetu("河圖") and Luoshu("洛書") too. Furthermore, by interpreting Yongjiu(用九) and Yongliu(用六), which belong to Qiangua(乾卦) and Kungua(坤卦) as prognostication that will be referred to when all six-line symbols are changed, he had made a great contribution to the history of Zhouyi("周易") study. Zhuzi(朱子) is responsible for a sizable part of the history of Zhouyi("周易") study as much as Wangbi(王弼) and Chengyi(程?). Of course, there are some parts where efforts were made in vain, however, the method to interpret the Zhouyi("周易") have developed day by day owing to the efforts of Zhuzi(朱子).

  • With the advent of the post-COVID19 era, people must maintain social distancing to quarantine. However, this rule deprives people of freedom. Therefore, this study proposes a new normal plan for urban park design using drive-thru to recreate space for people to maintain and enjoy their previous lives while complying with quarantine rules. Olympic Park has a large floating population, and is one of the places where drive-thru is available. Therefore, the study designed this place to be the only cafe that could be operated if other cafes were shut down due to social distancing. The cafes in the park were designed into five spaces based on Olympic Park's flag motifs. The results were as follows. The cafe's name is CUPPY (Cup+Coffee), while each logo letter is expressed using the colors of the Olympic flag: blue, yellow, black, green, and red. The cafe spaces were divided into five continents (Europe, Asia, Africa, Oceania, and America), as symbolized by the Olympic flag, with the driving route shaped like the Olympic logo to match the five spaces. Human beings need change and adaptation in various fields to live in a post-COVID19 era that they have never experienced before. Just as the New Normal changes with time, and should, research is essential for presenting a New Normal in urban park design that reflects this disaster situation following the COVID-19 crisis. On this very point, we expect that this research will serve as a reference for urban park design. Additionally, it is believed that continuous suggestions and research will be necessary to apply the model to more diverse environments.

  • The cumulative standard is one of the criteria determining the origin of imported goods and is a provision that allows non-origin materials to be treated as origin goods when satisfying certain conditions. Regarding the Korea-Canada FTA, new cumulative standards were applied concerning cross accumulation of automobile products. It would benefit U.S. originating intermediate goods of HS code chapter 84, 85, 87, and 94 obtained into HS code heading from 8701 into 8706. We examine the effectiveness of crossover cumulative standards through the change in the import values of 84, 85, 87, 94, which are target items for cross cumulation. Only items designated for automobile parts were selected and analyzed. From the estimation results, significant changes appeared in 20 of the 35 items. It was found that the import amount increased significantly as of January 2015 or the rate of change in trend increases more than before. In addition, the estimation results show that Korean auto companies utilizing the cumulative standards through increased imports of auto parts form the U.S.

Birth and Transformation of the Concept of "Oriental-ness" in Korean Art (한국미술에서의 동양성 개념의 출현과 변형)

  • Orientalness is a concept that expresses the collective identity of the Orient in relation to the West. The concept itself is mutable and defined by the relationship between the two regions at different points in time. Changes in the concept depend on a number of factors, such as cultural influence, the political balance of power between the two regions, and on the interpretative scheme that defines the relationship. In addition, the geographical notion of the concept evolves culturally, socially and politically. During this process, Oriental-ness becomes Oriental-ism at times. I will attempt to survey and measure the progression of Orientalness from its emergence in early 17th century to its subsequent transformation in modern Korea as reflected in art theory and art works. The recognition of the comparative characteristics of Oriental art began when the Orient was exposed to the art of the West in the late Ming dynasty during the early 17th century. The changes in the artistic climate in China affected the late Chosun. I will start with a brief introduction of this time and the birth of Orientalness. The concept gradually changed during the period of Enlightenment(開化期) towards the end of the 19th century, and during the colonial period( 1910-1945) it took on a new form. Establishment of the concept of "Orient"as a single, unifying concept spanning across cultures and national boundaries has been attributed to late Meiji period Japan, whose intention at that time is believed to have been to build a pan-Asia(亞細亞) empire with Japan at its commanding center. It has been stressed that the real motive behind the formation of one single cultural unit, where the shared common written language was Chinese and Confucianism and Taoism were the common metaphysical traditions, was to build one political unit. When the notion of a geographical unit of Asia was replaced by the concept of Asia as a cultural and political unit, a massive growth of interest and discourse were provoked around the concept of Orientalism. When Orientalism was being formulated, Korea automatically became member of "one Asia" when the country became colonized. For Koreans, the identity of the Orient had to be defined in cultural terms, as the political notion of a nation was non-existent at that time. The definition of identity was pursued at two levels, pan-Asian and local. If Orientalism was an elite discourse centered in pan-Asian philosophical and religious tradition, localized Orientalism was a popular discourse emphasizing locality as the byproduct of natural geographic condition. After the liberation in 1945 from colonial rule, a thrust of movement arose towards political nationalism. Two types of discourses on Orientalism, elite and popular, continued as central themes in art. Despite the effort to redefine the national identity by eradicating the cultural language of the colonial past, the past was enduring well into the present time. As discussed above, even when the painting themes were selected from Korean history, the tradition of using history painting as a manifestation of political policy to glorify the local identity had its founding during the Meiji period. The elevation of folk art to the level of high art also goes back to the colonial promotion of local color and local sentiment. Again, the succession of the past (colonial) ideal was defended as the tradition assumed a distinct modern shape that was abstract in style. The concept of the "Orient" is of relative and changing nature. It was formulated in relation to Western culture or civilization. Whatever the real motive of the adoption of them had been, the superiority of the Orient was emphasized at all times. The essence of the Orient was always perceived as the metaphysical tradition as a way to downgrade Western culture as materialistic. This view still prevails and the principle of Orient was always sought in Confucianism, Taoism, and Buddhism. Even when Orientalism was employed by imperialist Japan in an effort to establish her position as the center of the Orient, the spiritual source was still in Chinese philosophy and religion. In art also, the Chinese literati tradition became the major platform for elite discourse. Orientalism was also defined locally, and the so-called local color was pursued in terms of theme and style. Thus trend continued despite the effort to eradicate the remnants of colonial culture long after liberation. These efforts are now being supported politically and also institutionalized to become the aesthetic ideal of the modern Korean art.

  • The current air transportation industry is facing a lot of changes not only in the quantitative growth of the market, but also in the legal aspects. For many years, the Warsaw Convention has contributed to the uniform discipline of civil carriers' legal liabilities arising from international aviation accident and has fulfilled the duties of legal guardians for the development of the air transport industry. In the process, however, the consumer interests of the air transport industry did not have much protection compared to other industries. In response, the Montreal Convention has effected for protecting the interests of aviation consumers, and there are numerous legal changes around the world to protect aviation consumers like passengers. The mental damages of airline passengers arising from the accident can also be understood as part of the protection of air consumers. Considering that the US Federal Court has dealt with the recognition of mental damages for air passengers since the early 1990s. However, Korean judicial precedent still excludes mental anguishes from the scope of damage compensation. From this point of view, it is considered academically meaningful to analyze the latest case of the US federal court. Recently, the United States Court of Appeal for the Sixth Circuit in Doe v Etihad Airways applied a different interpretation against the traditional opinion: passengers could not recover for mental distress unless that mental distress resulted from a bodily injury sustained in an airplane accident. The background of the court's conclusions can be explained in many ways, among other things, unlike the Warsaw Convention the new international rule, Montreal Convention is recognizing the importance of ensuring protection of the interests of consumers in international carriage by air and the need for equitable compensation based on the principle of restitution.
