As IT technology develops rapidly and the personal dissemination of smart devices increases, video material is especially used as a medium of information transmission among audiovisual materials. Video as an information service content has become an indispensable element, and it has been used in various ways such as unidirectional delivery through TV, interactive service through the Internet, and audiovisual library borrowing. Especially, in the Internet environment, the information provider tries to reduce the effort and cost for the processing of the provided information in view of the video service through the smart device. In addition, users want to utilize only the desired parts because of the burden on excessive network usage, time and space constraints. Therefore, it is necessary to enhance the usability of the video by automatically classifying, summarizing, and indexing similar parts of the contents. In this paper, we propose a method of automatically segmenting the shots that make up videos by analyzing the contents and characteristics of language education videos and indexing the detailed contents information of the linguistic videos by combining visual features. The accuracy of the semantic based shot segmentation is high, and it can be effectively applied to the summary service of language education videos.

As container vessels get larger, container terminals are also likely to grow. The problem that arises is that the growing volume should be handled in the same amount of time as before. Container terminals are introducing an automation system in order to overcome the limitations of existing manual methods and to continuously reduce operating expenses. Because, Manual handling of carrying containers gate in and out of terminals causes inaccurate data, which results in confusion. An alternative is for containers to be labeled with barcodes that can be scanned into a system with a scanner, but this takes quite a long time and is inconvenient. A RFID system, also known as a gate automation system, can solve these problems by reducing the time of gate management with a technology that detects number identification plates, helping operators more efficiently perform gate management work. Having said that, with this system, when container damage is detected, gate operators make and keep documents manually. These documents, which are insufficient evidence in proving container damage, result in customer claims. In addition, it is difficult for gate operators and other workers to manage containers, exposing them to danger and accidents. This study suggests that if an automation system is introduced at gates, containers can be managed by a video storage system in order to better document damage The video system maintains information on container damage, allowing operators the ability to search for videos they need upon customer request, also allowing them to be better prepared for customer claims. In addition, this system reduces necessary personnel and risk of accidents near gates by integrating a wide range of work.

Background: The advances in surgical techniques, anesthesia management, perfusion methodology and postoperative intensive care have markedly decreased the mortality and cardiac morbidity of patients who undergo heart surgery over the past 2 decades. Nevertheless, it is well recognized that cardiac surgery carries a substantial risk for central nervous system complications. This study was conducted to evaluate the prevalence of subclinical cerebrovascular lesions in the head and neck by performing magnetic resonance angiography (MRA), and we investigated the clinical course of patients who had abnormal lesion seen on head and neck MRA. Material and Method: The subjects were 107 patients (71 men and 36 women ranging in age from 21 to 83 years) who were scheduled for cardiac surgery under nonemergency conditions between October 2005 and June 2008. Informed consent was obtained before the MRA. The carotid arteries, intracranial arteries and brain parenchyme were examined for subclinical cerebrovascular lesions by performing MRA. We reviewed the patients' medical records and MR findings to evaluate the prevalence of neurologically high risk patients and their clinical course. Result: The overall prevalence of neurologically high risk patients was 15.7% (17 patients). Among these patients, 11 patients had ischemic heart disease and 6 patients had valvular heart disease. Only 2 patients had a history of cerebrovascular disease. The clinical courses of 14 patients (13.1%) were changed according to their MRI findings. Conclusion: The prevalence of subclinical cerebrovascular disease in patients who were scheduled for cardiac surgery was higher than was expected. MR angiography was of value to identify these patients.

In 2006, the Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC) plans to undertake (subject to receiving the necessary approvals) a Pilot program for $CO_2$ storage within a depleted gas reservoir. The Otway Basin Pilot Program (OBPP) aims to demonstrate that subsurface $CO_2$ storage is both economically and environmentally sustainable in Australia. This will be the first $CO_2$ storage program in the world to utilise a depleted gas reservoir and, hence, the experience gained will be a valuable addition to the range of international $CO_2$ storage programs that are underway or being planned. A key component of the OBPP is the design of an appropriate geophysical monitoring strategy that will allow the subsurface migration of the $CO_2$ plume to be tracked and to verify that containment has been successful. This paper presents the results from modelling the predicted gravity response to $CO_2$ injection into the Otway Basin reservoir, where the goal was to determine minimum volumes of $CO_2$ that may be detectable using non-seismic geophysical techniques. Modelling results indicate that gravity measurements at 10 m spacing within the existing observation well and the planned $CO_2$ injection well would provide excellent vertical resolution, even for the smallest $CO_2$ volume modelled (10000 tonnes), but resolving the lateral extent of the plume would not be possible without additional wells at closer spacing.

In the midst of continuing international recession, the rate of maritime traffic and marine leisure markets are consistently growing. The Republic of Korea controls the marine traffic volume through vessel traffic centers and various other management facilities. Nevertheless, the continuous growth and complexity of marine traffic is resulting in repeated occurrences of marine accidents. Recovery is very difficult in cases of human injuries or deaths caused by marine accidents due to its nature, and the scale of marine accidents is also becoming greater with advanced ship building technologies. Passenger ships, oil tankers, and other such vessels used for specific purposes requires a more detailed navigational status surveillance and analysis, and numerous research has been conducted with an objective for monitoring such special purpose vessels. However, the data elements transmitted from the ocean to the shore station are limited to AIS and ARPA. We are implementing IoT ship sensor collection and a syncing system capable of transmitting various ship sensing data to the shore station, and also proposing a Safe Navigation Status Analysis System utilizing the collected data.

The purpose of this study was to determine the possibility of character education in the middle school home economics program: by extracting learning factors that can cultivate gratitude disposition from the eighth grade in the unit of 'clothing life' of middle school HE text, developing five teaching-learning lesson plans and learning materials, and applying them in classrooms to see any changes in gratitude disposition standards before and after its application. Five teaching-learning lesson plans for the cultivation of gratitude disposition were developed, and completed after three experts in home economics verified their validity and revised them. From June 1, 2010 to June 30, 2010, five classes were to 210 grade students at a Gyeongbuk Junior School, and dispositions were investigated before and after the classes. Gratitude disposition standards used GQ-6, like McCullough, and for before-and-after-inspection comparison, t-test and analysis of open-ended questionnaires were carried out. The results proved the instruction effective. Before the class for the cultivation of gratitude disposition, students had a gratitude disposition average of 2.87(out of 5). After the class, the average was 3.35, which shows that students had improved considerably. Also, in analysis of a open-ended questionnaire, it was said that the class had been provided the opportunity to think about the value of nature and neighbors and that the class content reminded them about appreciation. In conclusion, for the character education in other areas of middle school home economics, teaching-learning lesson plans development must be attained to further this character education program.

According to the development of technology of the navigational equipments, many bridge equipments have been improved, however, marine accidents by human error have not been reduced. Therefore, a matter of primary concern is focused on whether bridge equipments of ships are ergonomically arranged to reduce errors due to human factors. As part of a design of IBS(Integrated Bridge System) standard, rules of the conning display to save time and additional movements to obtain important informations of a ship should be established as soon as possible. In the present study, ergonomic design factors for the conning display are studied through the survey of related works, heuristic evaluations, sketch method tests as well as questionnaires. Using these factors, new conning display was designed and the ergonomic indices were evaluated by comparing tests of the existing conning displays. It is found that the designed conning display obtained high ergonomic index showed better performance, therefore, the ergonomic index studied in the present paper can be used as a useful design standard in the conning display design procedures.

The promotion of economic exchange and cooperation between North and South Korea is significant in two ways. First, the pursuit of economic interest can lead gradually to the unification of the national economies. Second, economic relations can serve as the first stride toward political reunification. There are, however, many difficulties in conceiving a strategy for economic cooperation between North and South Korea because of their differences in ideology and socio-economic system. Under these circumstances, a bid by either the North or the South to consider its specific ideology or socio-economic system absolute and to impose them on the other side would inevitably lead to confrontation and collision and deepen the division of the country. Therefore, steps to expand and develop economic and technological cooperation and comprehensive exchanges between the North and the South, with due regard to the development of bilateral relations, are in full accord with the interests of the both sides. It is clear that North Korea's changing attitude toward its environmental conditions is neither a policy of opening nor an ideological shift toward pragmatism, as has occurred in the Eastern European countries. Instead, it is a temporary tactic for breaking out of the economic stagnation caused by its rigid economic structure. In this light, we must.
