The objective of the study was to identify the structural relationship between adolescent athletes'positive thinking and coping flexibility, burnout. In order to achieve such research goal, male and female athletes'from physical education middle and high schools across the nation were recruited; using a convenience sampling method, a total of 333 samples were selected as the final effective samples. The data went through a goodness-of-fit test for the whole model using SPSS 20.0 and AMOS 20.0 and a hypothesis test. The result is as follows: first, positive thinking was revealed to have significant influence on coping flexibility. second, repertories and flexible a subfactor of coping flexibility, had significant negative (-) effects on burnout, whereas reflective had no significant effects on it. Third, positive thinking was revealed to have no significant influence on burnout. In conclusion, although positive thinking is a variable that is based on internal information, positive thinking did not directly affect psychological burnout, but coping flexibility can be used to prevent burnout.

Recently, high-speed internet subscribers have grown continuously, and reached up to 10 millions. But existing network management that is responsible only for user access is confronted with many difficulties, since user access network(xDSL, Cable, B-WILL, and so on) has diversified and value added wired/wireless contents service has developed. In this paper propose the Agent based Inter Networking platform as object-oriented hierarchical system that can provide various service such as access QoS(Quality of Service), customized application service and security service according to user on demand. This system has divided into two parts(user agent and agent management system ＆ local and central management systems). Management system periodically receive status information such as bandwidth, download speed, delay, current service, and so on, and process them, then build a policy based on processed information. According to personal user profile that is generated by this policy, the customized service can be provided for users. And This system adopt the object-oriented modeling in case that system migration and integration, and implement a system that is robust and stable for security through hierarchical server system.

In this paper, we propose ubiWarehouse system which can efficiently manages mass and many kinds of parts such as automotive parts. First, user's work situation is defined systematically as context type of 5W1H, context-aware system is separated on function, and each module operates independently. An efficient route is selected and relevant parts frequently treated at the same time are gathered by calculating the suitability of parts and racks. If other users currently are on a visit or are supposed to visit soon, the hun of visit is changed making a concession for preventing collision. As a result, the proposed system with avoiding competition can provide users with routes for inbound or outbound parts, and can effectively use spaces of a warehouse by arranging racks to gather relevant parts to near location. Also, individual service can be offered by evaluating user propensity using history of the warehouse job, and the accuracy of stock information can be improved by processing of unexpected context and real-time renewing of warehousing and delivering.

Automatic detection of objects in images has been one of core challenges in the areas such as computer vision and pattern analysis. Especially, with the recent deployment of personal mobile devices such as smart phone, such technology is required to be transported to them. Usually, these smart phone users are equipped with devices such as camera, GPS, and gyroscope and provide various services through user-friendly interface. However, the smart phones fail to give excellent performance due to limited system resources. In this paper, we propose a new scheme to improve object recognition performance based on pre-computation and simple local features. In the pre-processing, we first find several representative parts from similar type objects and classify them. In addition, we extract features from each classified part and train them using regression functions. For a given query image, we first find candidate representative parts and compare them with trained information to recognize objects. Through experiments, we have shown that our proposed scheme can achieve resonable performance.

This study was conducted to investigate the apraxia affects activitys of daily living. 38 patients with stroke were participated and conducted to both Birminham Cognitive Screen(BCoS) apraxia test and K-MBI for ADL. Using a cutoff score of BCoS apraxia test, all patient was determine whether with apraxia or not and were distinguished by various types of apraxia. They were compared to the level of ADL using ANOVA. Apraxia patients 18, patients without apraxia is 20. The difference of ADL between the two groups was not. However, the result of classifying patients with apraxia subtypes, it showed a significant difference in grooming, eating, toileting, step, bowel control, and bladder control(F=4.431~9.193, p<0.05). As apraxia is cause of a negative effect on ADL, expert in the area to manage stroke patients should have to share information about whether apraxia is or not and make policy and treatment program considering the potential problem in ADL.

RFID is core technology to lead ubiquitous computing, and attract the notice of the world. It also improves social transparency, creates employment, and invigorates the allied industries. However, The technical characteristic with RFID has some problems with security and privacy. The commercialization of RFID is delayed due to these problems. This paper introduces the technical method to find solutions about an invasion of privacy to be due to introduce RFID system. First, this method applies Hash-Chain proposed by M. Ohkubo and some other researchers. The more tags increase, the more it demands lots of computation time. We divide SPs equally to solve these problems. And then, We'll suggest solutions to shorten the identification time of tag by implementing SPs with multi nodes of Grid environment at the same time. This makes it possible to keep the privacy protection of RFID tag, and process RFID tag in real time at the same time.

근래 우리나라에서도 평균수명이 길어져 노동의욕이 있는 중고령자가 증가하는 한편, 출산율이저 하되어 젊은 근로자의 수가 감소되고 있다. 통계청의 인구통계과의 추계에 의하면 2000년에는 60세 이 상이 총인구에 점하는 비율이 10.7%, 65세 이상은 6.8%가 되고, 2020년에는 60세 이상이 19.5%, 65세 이 상도 12.5%에 도달한다는 것이다. 인구노령화로 인한 고령화 사회에 대한 준비를 서둘러야 할 때라고 생각된다. 또 고령화 사회로 되면 젊은 연령층의 경제적 부담이 증가되므로 중고령자의 노동인구를 이대 로 방치해 두는 것은 국가적으로나 사회복지적으로나 불경제라고 할 수 있다. 그런데, 문제가 되는 것은, 중고령자를 취업시키는 것이 오히려 사회의 생산성을 저하시키거나 경제적으로 불리하게 되어서는 안되는 것과 중고령노동자 자신의 안전을 확보해야 하는 것이다. 이러한 문제를 해결하기 위해서는 고용에 있어 서 어떠한 점에서 중고령노동자에게 특징과 문제가 있는가를 분명히 할 필요가 있다. 고령자는 청년자 보다 노동능력이 떨어지는 특징과 문제가 있는가를 분명히 할 필요가 있다. 고령자는 청년자 보다 노동능력이 떨어지는 경향이 있지만 개인차도 크고 고령자 중에는 청년자의 기능에 비교해도 뒤떨어지지 않는 자도 있다. 연령만으로 노동능력을 판정하는 것은 적절한 방법이라고 할 수 없다. 문헌에 의하면 역연령(chornological age)이 25세의 경우, 생리적 연령은 23세에서 27세로 4년 차이가 있다고 한다. 이러한 생리적 연령의 차이는 역연령이 더해감에 따라서 점차 크게 되어 역연령이 45세에서는 12년, 80세 에서는 20년이나 된다는 것이다. 이것은 인간에 있어서 시간적 경과를 나타내는 역연령 이외에 신체적 기능연령(functional age)가 있다는 것을 의미하는 것이다. 한편, 생산현장에서는 자동화, 기계화가 진보되어 육체적인 노동이 경감된 결과, 중고령자라도 할 수 있는 작업이 많아지고 있다. 또, VDT (Visual Dislay Terminal) 작업과 같은 정보처리 작업의 수요가 증가하여 그 인재의 부족이 지적되고 있다. 따라서 중고령자의 기능을 조사하여 어떠한 작업에 적합한가를 판단하는 것이 중요한 과제로 되었다. 그러나 노동에는 많은 기능이 관여 하고, 그 내용에 따라서 요구되는 기능이 서로 다르기 때문에 노동적응능력의 기본적인 기능으로 보여지는 것에 좁혀서 작업능력의 연령증가 변화에 대하여다원적 평가를 하는 것이 실제적이라고 할 수 있다. 따라서 본 연구에서는 인간이 가지고 있는 다수의 기능중에서 수지교 치성과 연령증가와의 관계를 조사한다. 만약 연령증가 만으로 수지교치성을 평가 할 수 없는 경우에는 어떠한 요인이 수지기민성의 변화에 영향을 미치는가를 검토한다.

This work presents an ECG biometric recognition system for the purpose of biometric authentication. ECG biometric approaches are divided into two major categories, fiducial-based and non-fiducial-based methods. This paper proposes a new non-fiducial framework using discrete cosine transform and a Random Forest classifier. When using DCT, most of the signal information tends to be concentrated in a few low-frequency components. In order to apply feature vector of Random Forest, DCT feature vectors of ECG heartbeats are constructed by using the first 40 DCT coefficients. RF is based on the computation of a large number of decision trees. It is relatively fast, robust and inherently suitable for multi-class problems. Furthermore, it trade-off threshold between admission and rejection of ID inside RF classifier. As a result, proposed method offers 99.9% recognition rates when tested on MIT-BIH NSRDB.

The government and private companies are endeavoring to help the digital healthcare industry grow. This includes easing regulations on the big data industry such as the amendment of the Data 3 Act. Despite these efforts, however, there have been constant demands for the amendment of laws related to the medical field and for securing medical data transmissions. In this paper, the Data 3 Act of Korea and the legal system related to healthcare are examined. Then the legal, institutional, and technical aspects of the strategies are compared to understand the issues and implications. Based on this, a legal and institutional strategy suitable for the digital healthcare industry in Korea is suggested. Additionally, a direction to improve social perception along with technical measures such as safe de-identification processing and data transmission are also proposed. This study hopes to contribute to the spread of various convergent industries along with the digital healthcare industry.
