Though conventional video surveillance systems such as CCTV depended on operators, recently developed intelligent surveillance systems no longer needed operators. However, these new intelligent surveillance systems have their own problems such as Occlusion, changing scale of target object, and affine. This paper handled information damage caused by changing the scale of the target object among other objects. Due to the change of the scale, the inaccurate information of target can be obtained when we update the background information. To handle this problem, we introduce a solution for information damage caused by problem of changing scale of target object located among other objects. Specifically, we suggest multi-stage sampling particle filter based advanced MSER for object tracking system. Through this method, the problem caused by changing scale of target can be avoided.

Purpose: The open abdomen is now the standard of care in various clinical situations, especially it is used to treat abdominal compartment syndrome. Many techniques have been reported for closure after an open abdomen, but most take a long time for complete definitive closure and are associated with various problems. We describe a technique using biologic mesh that can achieve early definitive closure after an open abdomen. Methods: A 45-year-old man presented to the emergency room with a painful hip and painful lower extremities after a fall from 80 feet. Radiologic examination revealed multiple fractures of the pelvis and low extremities. Abdominal compartment syndrome caused by a retroperitoneal hematoma developed during the orthopedic surgery. We performed exploration immediately and closed abdomen temporarily. A peritoneal graft of porcine dermal collagen with anterior myofascial approximation of the rectus abdominis muscles and sliding skin flap was performed three days after the previous surgery. Results: There were no complications related to the wound. The patient was transferred to the Department of Orthopedic Surgery seven days after the initial surgery. Conclusion: Early definitive closure using porcine dermal collagen is a feasible method that can reduce the length of hospitalization and the number of operations for an open abdomen.

In recent years, the definition of corporate governance is a stakeholder-oriented corporate governance that can meet the needs of sustainability management and corporate social responsibility. The purpose of this study is to empirically analyze the effect of corporate governance on employees and creditors corporate governance on earnings management by using regression analysis. The results show that the corporate governance of employees and creditors plays a role in reducing the simultaneous profit management of discretionary accruals, which is the accrual of asset impairment loss, which is the accrual of negative I could confirm. The results of the empirical analysis show that stakeholder-centered corporate governance can play a role in controlling managers' behavior and market. In addition, the results of this study suggest that the responsibility of stakeholders as corporate governance is important for sustainable management of modern corporations where corporate social responsibility is important.

Objectives：The study was performed to compare the executive function(EF；Inhibition, Planning and Working memory) between ADHD and normal group, and to controll the effect of age and intelligence. And the function of inhibition was assessed in two dimensions(cognitive inhibition and motor inhibition). Methods：K-WISC III and EF test(Go-No-Go, Stroop test, Tower of Hanoi, Digit) was administered to both 25 children with ADHD and 25 normal control participants, all aged between 7 and 12. The results were analyzed after statistically controlled for age and intelligence. Results：Children in the ADHD group had significantly lower IQ score than those in the control group and consistent relations were found between the child's age and the study's major variables. Once IQ and age were controlled, results indicated that children with ADHD had deficit only cognitive inhibition and motor inhibition. There was no significant difference in planning and working memory. Conclusion：These results suggested that specific deficits in inhibition control rather than general EF deficits are associated with ADHD. So inhibition is the core problem of children with ADHD. Thus, the therapeutic approach focused on cognitive inhibition and motor inhibition is required.

As the cyber threats of nuclear power plants become more necessary to systematically prepare against the cyber attack, the international community and the domestic government are urged to apply proper security controls for Critical Digital Assets (CDA) through cyber security regulatory guidelines. In this study, we suggests the application of security controls to develop the regulatory requirements of the graded approach through the analysis of domestic and foreign cyber security regulation guidelines and best practices for digital assets directly related to nuclear accidents. In order to apply the regulatory requirements based on the consequence(impact of infringement) of the regulated facility, which is a basic consideration of the graded approach, we will classify two methods and describe details of each method. By reanalyzing existing security controls, it is introduced that the method of demanding digital assets directly related to accident to enhance security controls required for existing CDA or develop additional security controls and requiring minimum security controls for CDA that are not directly related to accident.

자동차의 안전도는 전통적으로 정면 충돌시 승객의 보호 정도를 가지고 비 교 된다. 그러나 근래에 와서는 다양한 사고에 의한 승객의 피해를 볼 때 정면 과 더불어 측면 충돌시의 피해를 무시할 수 없는 상태에 이르렀다. sled tests 등을 통해서 정면 뿐만 아니라 측면 충돌의 영향도 파악하고 있으나 정면 충돌보다 측면 충돌에 대해 승개 보호 장치의 개발이 미흡한 것이 현실이다. 본 연구에서는 현실적으로 보다 효과적인 occupant (운전자 및 승객) restraint system을 computer 모의 실험을 통해서 제안하고자 하였다. 기존의 안전시스템인 lap/shoulder belt system과 Air cushion에 의한 실험은 다각도로 연구되었다. 그러나 측면 충돌에서 Air Bag에 의한 충돌 감소 영향은 정면 충돌에 비해 적어지게 되어 상체 측면 보호 장치가 필요하게 된다. 본 연구에서는 운전자의 lap/shoulder belt system과 Air Bag에 의해 구속되는 dummy를 가지고 다양한 측면 충돌 각도 (0 .deg. , 15 .deg. , 30 .deg. , 45 .deg. , 70 .deg. )에서 실험이 수행되었다. 또한 각 충돌각에 대해 기존 Restraint System에 상체 측면 보호 장치(seat wing)를 포함하여 실험을 수행 하였다. 이에 대한 각각의 영향, 그리고 승객 손상도 분석 및 평가를 통하여 보안된 측면 충돌 보호 restraint system의 필요성과 그 효과를 제시하고자 한다. 실험결과 에 의하면 정면보다 측면에서 충돌하였을 경우 보조 구속 시스템인 seat wing으로 인 해 측면보호는 물론 occupant는 정면으로 나가게 개선되어 구속 시스템으로써의 이점이 확대되고 shoulder blet 또는 dummy의 감속을 통제하는 Air Bag의 잠재적인 이점이 더욱 확대되었음을 보여주고 있다. 그러나 design 단계에서 편안함, 안락감 등의 문제들과, 다른 실용적인 면에 대한 계속적인 연구가 필요하다.

This study was conducted to identify the relationship between depression and subjective/objective health status, and to examine predicting factors on depression in the elderly in Korea. This study was a secondary analysis using the data of Korea National Health and Nutrition Examination Survey(VI-1) 2007. A total of 939 data from the subjects ≥60 years who completed health-related survey were used for analysis. Data were analyzed using SAS (version 9.1) PC program. Depression was identified in the 20.3% of the older subjects. Multiple logistic regression analysis showed that women (OR=2.04), senior high school graduation (OR=0.27) and lowermiddle household income (OR=2.83) were significant associating factors(p<0.05). After adjustment for socio-demographic factors, hypertension (OR=1.93) and asthma (OR=3.32) as objective health status, and stress (OR=7.27), limited activity in daily living due to fracture or joint injury (OR=6.59) and poor self-rate health (OR=1.64) as subjective health status were found as factors predicting depression in the elderly(p<0.05). According to the type of health status, the subjects who had chronic disease or perceived poor physical health were 5.94 times more likely to have disposition to depression than the subjects who had no chronic disease or perceived good physical health (p=0.001). These findings suggest that preventive education and intervention focus on preventing and managing chronic diseases such as hypertension, asthma, fracture and joint injury should be needed to decrease depression in the elderly.

The Russo-Japanese War(1904-1905) in the early 20th century greatly influenced the international politics in Northeast Asia and the destiny of both countries. There are many studies on the cause of the outbreak and its effect on the Korean peninsula. The victory and defeat of the battle of Tsushima also the subject of research by renowned scholars and navy officers. Many previous studies have analyzed the process of engagement. However, There was a lack of research that analyzed at the tactical level of naval commanders. Therefore, this study tries to review the battle of Tsushima in terms of tactical level, that is formation, maneuvering, damage control. Naval operations at sea with many variables are not always done as planned. The intuitive judgement and readiness have had a decisive impact on victory and defeat. The analysis of the naval warfare on the basis of formation, maneuvering, and damage control makes the cause of the win more clearly. The conclusion of the this study can be summarized in five ways. First, victory would be achieved through the suppression of the beginning. The destiny of the Tsushima battle was determined by an 1 hour after first firing. The Japanese fleet caught fire by paralyzing the command and control capabilities of the Russian fleet. Second, the Japanese fleet's power was superior to the Russian fleet. In general, Japan and Russia had similar powers, and Admiral Togo's "T crossing tactics" decisively contributed the victory. However, when compared to the weapon system level, formation and maneuvering, Japan was much more dominant. Third, people realized that one side to be annihilated in the battle between similar powers after the Tsushima battle. The common perception before the Battle of Tsushima was that the battle ship would not sunken, and that the result of wiping out was difficult. However, there is s time for one sided victory and defeat depending on the early suppression nad the destruction of the command and control ability. Fourth, it is the importance of damage control ability. The main cause of the Russian fleet's loss of command and control ability was thick smoke from fire, and maneuverability was greatly deteriorated due to coal overload. In this way, importance is still valid after more than 100 tears. Fifth, the area of uncertainty. In the navy battles, one or two shots of clear firing in the beginning and small misconception and minor mistakes decide win or loss. Ultimately, this area of fortune can be linked to mindset of the commander. I hope this research will be help to naval researchers and naval commanders at the sea.
