  • This paper presents a method to segment the object of interest from a set of multi-view images with minimal user interaction. Specifically, after the user segments an initial image, we first estimate the transformations between foreground and background of the segmented image and the neighboring image, respectively. From these transformations, we obtain regions in the neighboring image that respectively correspond to the foreground and the background of the segmented image. We are then able to segment the neighboring image based on these regions, and iterate this process to segment the whole image set. Transformation of foregrounds are estimated by feature-based registration with free-form deformation, while transformation of backgrounds are estimated by homography constrained to affine transformation. Here, both are based on correspondence point pairs. Segmentation is done by estimating pixel color distributions and defining a shape prior based on the obtained foreground and background regions and applying them to a Markov random field (MRF) energy minimization framework for image segmentation. Experimental results demonstrate the effectiveness of the proposed method.

  • A grape fruit is required for a lot of labor to harvest in time in Korea, since the fruit is cut and grabbed currently by hand. In foreign country, especially France, a grape harvester has been developed for processing to make wine out of a grape, not to eat a fresh grape fruit. However, a harvester which harvests to eat a fresh grape fruit has not been developed yet. Therefore, this study was designed and constructed to develope a image processing system for a fresh grape harvester. Its development involved the integration of a vision system along with an personal computer and two cameras. Grape recognition, which was able to found the accurate cutting position in three dimension by the end-effector, needed to find out the object from the background by using two different images from two cameras. Based on the results of this research the following conclusions were made: The model grape was located and measured within less than 1,100 mm from camera center, which means center between two cameras. The distance error of the calculated distance had the distance error within 5mm by using model image in the laboratory. The image processing system proved to be a reliable system for measuring the accurate distance between the camera center and the grape fruit. Also, difference between actual distance and calculated distance was found within 5 mm using stereo vision system in the field. Therefore, the image processing system would be mounted on a grape harvester to be founded to the position of the a grape fruit.

  • This study tries to give improvement directions of the law of oil spill focusing on the view that satisfying remuneration for victims should be considered. And it looks through the existing remuneration system provided by P&I Club and IOPC Fund. It also covers with issues related to remuneration in order to find the best for victims. The major contents of this study are as follows. First, the present law of compensation security to Marine oil pollution accident should be revised. Maximum value of remuneration needs to be raised and subjects liable to pay reparation need to be expanded. Second, in case the damage is widely different comparing to similar cases in foreign countries, it's hard to get complete remuneration from international corporations responsible for reparation. That's the reason the national emergency system for oil pollution must be established. Third, this study says the law that certainly defines a liability subject and that the liability is not necessarily caused by fault should be enacted. Last, it suggest that victims should have their object income data to facilitate establishment of the law of compensation for damages from marine oil pollution. To calculate proper remuneration, government should consider to choose one of public organizations as an investigator to damages and should collect accurate statistics relating to fishery. Furthermore, compensation system which can provide rapid reparation to victims needs to established by founding professional maritime organization of arbitration.

  • In Korea, the major of international trade and business introduced in the 1960s to supply trade expert to trading companies, and the heyday of the trade major was in the 1980s. However the trade major fell into decay from the middle of 1990s. The purpose of trade education in university is to supply high qualified employees to societies and companies. The problem is that companies have difficuties for recruiting of trade expert, on the other hand university graduates have few job oppertunies. It has some discrepancies between education and field. The object of this paper is to propose a direction of modification of the trade and international business curriculum for global trade expert. We research international trade and business departments' curriculums of GTEP universities. GTEP stands for global trade expert incubating program started from 2006 which have charge of MOCIE and KITA. First, in the title of department, a lot of former researchers have taken up the position to return "Trade" or "International Trade". We think more important fact is not the title of department but the curriculum, so we insist on a harmony between the department title and curriculums. The focus of modification of curriculum is to educate global trade expert, so we need to know about global business environment and companies' needs also. Second, We propose the directions for modification of curriculum are "convergence" and "specialty". Trade major is a mixed study in nature and trade major try to treat lots of subjects such as trade, business adminstration, economics, international law, international commerce, logistics and marketing etc to catch up changing global business circumstanses and companies' needs. So convergence of adjacent field is very important in study and training. Specialty means selection and concentration strategy for global trade expert. It is difficult to learn every knowledge and skills for employer's needs in 4 years and 140 credits. A students who has studied basic subject in trade, management, economics can choose 1 or 2 specailty subject such as trade and e-commerce, global marketing, logistics and transportation, commerce and policy, servive trade, foreign language and cross culture etc. In concusion, the concept of convergence and specialty is not separation but harmony each other, so we propose to promote two concept together for modification of the trade and international business curriculum for training of global trade expert.

  • 실시간 시스템이란 시간적인 제한을 가지고 작업 수행 결과의 정확도가 보장되는 시스템으로 경성 실시간 시스템과 연성 실시간 시스템으로 분류된다. 최근 분산 실시간 분야에서 새로운 패러다임으로써 폭넓게 활용되기 시작한 실시간 객체 모델인 TMO는 Kane Kim과 Kopetz에 의해 처음 제안되었다. TMO 모델은 경성 또는 연성 실시간 응용과 병렬 컴퓨팅 응용 프로그램에서 사용 될 수 있으며, 시스템의 기능적인 면과 시간 조건 수행 모두를 명확히 정의할 수 있다. TMO의 네트워크로 구성되는 실시간 분산 환경에서의 실행을 위해 몇 개의 TMO 실행 엔진이 개발 되었는데, 그 중에서 LTMOS라는 리눅스 기반의 연성 실시간 미들웨어 엔진이 한국외대 RTDCS lab.에서 개발되었다. 하지만 LTMOS의 실시간 시스템 수행 중 작업량의 과부하로 인한 deadline 위반이나, 시스템간의 분산 IPC 통신에 있어서 Channel Traffic이 빈번한 경우 실시간 시스템을 유지할 수 없다는 문제점들을 갖고 있다. 이러한 문제점들을 해결하고 조금 더 효율적인 실시간 시스템을 유지하기 위해서, TMO 프로그램의 resource 정보를 담고 있는 ODS(Object Data Store)만을 다른 노드에 있는 자신의 TMO 프로그램 Replica로 이주해서 실시간 로드 밸런싱을 구현하는 기법을 사용하였다. 이에 본 논문에서는 TMO 프로그램들의 deadline 위반 및 Channel Traffic 부하를 감지할 수 있는 Node Monitor와 최적의 노드를 선별할 수 있는 Migration Manager를 새롭게 추가하였고, 쓰레드들의 스케줄러인 WRMT에 이주 작업을 하기 위한 부가적인 기능을 구현하였다. 2D 이미지의 관측점을 줄여 계산량을 대폭 감소시키는 장점을 갖는다.것으로 조사되었으며 40대 이상의 연령층은 점심비용으로 더 많은 지출을 하고 있는 것으로 나타났다. 4) 끼니별 한식에 대한 선호도는 아침식사의 경우가 가장 높았으며, 이는 40대와 50대에서 높게 나타났다. 점심 식사로 가장 선호되는 음식은 중식, 일식이었으며 저녁 식사에서 가장 선호되는 메뉴는 전 연령층에서 일식, 분식류 이었으며, 한식에 대한 선택 정도는 전 연령층에서 매우 낮게 나타났다. 5) 각 연령층에서 선호하는 한식에 대한 조사에서는 된장찌개가 전 연령층에서 가장 높은 선호도를 나타내었고, 김치는 40대 이상의 선호도가 30대보다 높게 나타났으며, 흥미롭게도 30세 이하의 선호도는 30대보다 높게 나타났다. 그 외에도 떡과 죽에 대한 선호도는 전 연령층에서 낮게 조사되었다. 장아찌류의 선호도는 전 연령대에서 낮았으며 특히 30세 이하에서 매우 낮게 조사되었다. 한식의 맛에 대한 만족도 조사에서는 연령이 올라갈수록 한식의 맛에 대한 만족도는 낮아지고 있었으나, 한식의 맛에 대한 만족도가 높을수록 양과 가격에 대한 만족도는 높은 경향을 나타내었다. 전반적으로 한식에 대한 선호도는 식사 때와 식사 목적에 따라 연령대 별로 다르게 나타나고 있으나, 선호도는 성별이나 세대에 관계없이 폭 넓은 선호도를 반영하고 있으며, 이는 대학생들을 대상으로 하는 연구 등에서도 나타난바 같다. 주 5일 근무제의 확산과 초 중 고생들의 토요일 휴무와 더불어 여행과 엔터테인먼트산업은 더욱 더 발전을 거듭하고 있으며, 외식은 여행과 여가 활동의 필수적인 요소로써 그 역할을 일조하고 있다. 이와 같은 여가시간의 증가는 독신자들에게는 좀더 많은 여유시간을 가족을

  • In this study, we introduce the French concept of 'valorisation' of heritage which corresponds to 'utilization(활용)' of heritage in Korea. As interests on the social, economic and identity values of heritage are increasing, it is considered as not only a target of protection and preservation but also an object of utilization. Even though this global transition has been formed quickly, the concepts regarding utilisation of heritage has not been academically founded and its related foreign terms or cases were not studied in depth. In particular, modern cultural heritage requires more attention and researches on the protection and utilization as it represents a relatively large range of utilization but it doesn't have strong protection policies. We justify the needs to introduce the concept 'valorisation' in Korea while analyzing Le Havre case that shows how to promote economic and social values of heritage as well as heritage values from 'local' to 'country' and to 'world'. This case was selected as it allows to identify the meaning of valorisation and heritagization process from modernly rebuilt areas after World War II to World Heritage Site.

  • Recently, many companies improving their management performance by building a powerful brand value which is recognized for trademark rights. However, as growing up the size of online commerce market, the infringement of trademark rights is increasing. According to various studies and reports, cases of foreign and domestic companies infringing on their trademark rights are increased. As the manpower and the cost required for the protection of trademark are enormous, small and medium enterprises(SMEs) could not conduct preliminary investigations to protect their trademark rights. Besides, due to the trademark image search service does not exist, many domestic companies have a problem that investigating huge amounts of trademarks manually when conducting preliminary investigations to protect their rights of trademark. Therefore, we develop an intelligent similar trademark search model to reduce the manpower and cost for preliminary investigation. To measure the performance of the model which is developed in this study, test data selected by intellectual property experts was used, and the performance of ResNet V1 101 was the highest. The significance of this study is as follows. The experimental results empirically demonstrate that the image classification algorithm shows high performance not only object recognition but also image retrieval. Since the model that developed in this study was learned through actual trademark image data, it is expected that it can be applied in the real industrial environment.

  • The major object of this study is to analyze the political development of Myanmar's civilian government on the concept of defective democracy, and to investigate the main actors who delayed or stymied political development and their interrelation. In doing so, this study suggests the tasks required for political development overcoming the current political structure and behavior. The civilian government, which was launched in 2016, failed to achieve positive political development by following the behavior of military authoritarianism in terms of exercise of power and decision making structure. On the perspective of the government, delegative democracy and domain democracy have been strengthening since one person has taken over all political power and hesitate to take horizontal accountability for each power organizations. The military, which is responsible for national defence and security seeks illiberal democracy and exclusive democracy, keeping on an undemocratic constitution by the military and Burman ethnocentrism. The reasons why defective democracy has been occurred are that the lack of a group to run a democratic institutions and the limitation of power structure that fails to adhere to the principle of civilian control to the military due to long-term military rule. Therefore, there is a need for military's come back to barracks and transform the power structure to democratic of the civilian government which is tamed an authoritarian order for the political development in Myanmar. In order to achieve this, this study concludes that setting up a empowered democratic government is required.

  • The essence of the definition of "tolerance" is analyzed. Motivational, knowledge and behavioral criteria for tolerance of future teachers are highlighted. Indicators of the motivational criterion are the formation of value orientations, motivational orientation, and the development of empathy. Originality and productivity of thoughts and judgments, tact of dialogue, pedagogical ethics and tact are confirmed as indicators of the knowledge criterion. The behavioral criterion includes social activity as a life position, emotional and volitional endurance, and self-control of one's own position. The formation of tolerance is influenced by a number of factors: the social environment, the information society, existing stereotypes and ideas in society, the system of education and relationships between people, and the system of values. The main factors that contribute to the education of tolerance in future teachers are highlighted. Analyzing the structure of tolerance, it is necessary to distinguish the following functions of tolerance: - motivational (determines the composition and strength of motivation for social activity and behavior, promotes the development of life experience, because it allows the individual to accept other points of view and vision of the solution; - informational (understanding the situation, the personality of another person); - regulatory (tolerance has a close connection with the strong - willed qualities of a person: endurance, selfcontrol, self-regulation, which were formed in the process of Education); - adaptive (allows the individual to develop in the process of joint activity a positive, emotional, stable attitude to the activity itself, which the individual carries out, to the object and subject of joint relations). The implementation of pedagogical functions in the information society: educational, organizational, predictive, informational, communicative, controlling, etc. provides grounds to consider pedagogical tolerance as an integrative personal quality of a representative of any profession in the field of "person-person". The positions that should become conditions for the formation of tolerance of the future teacher in the information society are listed.

  • With the development of big data technology, data is rapidly entering a hyperconnected intelligent society that accelerates innovative growth in all industries. The convergence industry, which holds and utilizes various high-quality data, is becoming a new growth engine, and big data is fused to various traditional industries. In particular, in the medical field, structured data such as electronic medical record data and unstructured medical data such as CT and MRI are used together to increase the accuracy of disease prediction and diagnosis. Currently, the importance and size of unstructured data are increasing day by day in the medical industry, but conventional data security technologies and policies are structured data-oriented, and considerations for the security and utilization of unstructured data are insufficient. In order for medical treatment using big data to be activated in the future, data diversity and security must be internalized and organically linked at the stage of data construction, distribution, and utilization. In this paper, the current status of domestic and foreign data security systems and technologies is analyzed. After that, it is proposed to add unstructured data-centered de-identification technology to the guidelines for unstructured data and technology application cases in the industry so that unstructured data can be actively used in the medical field, and to establish standards for judging personal information for unstructured data. Furthermore, an object feature-based identification ID that can be used for unstructured data without infringing on personal information is proposed.
