Menstruation being an inevitable phenomenon for every women, reducing the discomfort during the menstruation period is one of the important issues for women's well-being. This study was conducted through user evaluations on disposable pads and reusable pads to comprehend the discomfort factors of the sanitary pads and to provide basic information for improvement. Negative symptoms of the reponses on menstruation outnumbered the positive aspects, and the results suggested that menstruation period was perceived as a painful experience to women. There were difference between the negative and positive responses regarding the designs, functions, fittings, wearing sensations. and disposabilities of disposable pads and reusable pads. While disposable pads had the strength of convenient use, it had the weakness of wearing sensation, and while reusable pads had the strength of wearing sensation, it had the weakness of inconvenient keeping. When designs reflecting these results are made, it is expected to bring a synergy effect by bringing both a more pleasant menstruation period for the consumers and eventual profit to the manufacturers.

Recently, WBI model which is based on web has been proposed in the part of the new activity model of teaching-learning. The demand for the customized coursewares which is required from the learners is increased, the needs of the efficient and automated education agents in the web-based instruction are recognized. But many education systems that had been studied recently did not service fluently the courses which learners had been wanting and could not provide the way for the learners to study the learning weakness which is observed in the continuous feedback of the course. In this paper we propose design of multi-agent system for course scheduling of learner-oriented using weakness analysis algorithm. First, proposed system monitors learner's behaviors constantly, evaluates them, and calculates his accomplishment. From this accomplishment, the multi-agent schedules the suitable course for the learner. The learner achieves an active and complete learning from the repeated and suitable course.

The purpose of the study is to explore the relationship between the type of reporting weaknesses in the Internal Accounting Control System and executive compensation, and then analyze whether such relevance varies depending on the characteristics of governance structure. The analysis data used 6,343 KOSPI&KOSDAQ companies excluding the financial industry from 2011 to 2016. As a results of the study, First, executive compensation decreased in companies reporting the weaknesses of CL. Second, this relevance was further strengthened according to the governance structure. This study confirms that information on the operation results of system is an important factor in determining manager compensation. It implies that it is necessary to study reasonable compensation policies and governance structures suitable for companies. If an internal control system that affects executive compensation is added, the basis for stronger support of the research results can be prepared.

Information which port provide to users including shipping companies is essential information for their business performance. Thus, information service of several services which port provide to shipping company is also very important port-logistics service. However, despite of this importance, there have been little research related to port-logistics information service. The aim of this study is to analyze the satisfaction of information service for port logistics. To achieve this objective, evaluation criteria consisting of 16 items based on the previous research was established. And satisfaction index that can effectively show the current level of information service for port logistics was developed. The results of analysis showed that satisfaction index of information service provided by Busan port was 61.90. And from the data analysis, it was revealed that current level of information service in whole area was less than 63 points. It was implied that improvement for overall port-logistics information service was needed. Finally, from the follow-up research, it was found that information service provided by Busan port have weakness in the aspects of unification of information and celerity of information.

In this paper we present a novel approach for image retrieval using color and edge information. We take into account the HSI(Hue, Saturation and Intensity) color space instead of RGB space, which emphasizes more on visual perception. In our system colors in an image are clustered into a small number of representative colors. The color feature descriptor consists of the representative colors and their percentages in the image. An improved cumulative color histogram distance measure is defined for this descriptor. And also, we have developed an efficient edge detection technique as an optional feature to our retrieval system in order to surmount the weakness of color feature. During the query processing, both the features (color, edge information) could be integrated for image retrieval as well as a standalone entity, by specifying it in a certain proportion. The content-based retrieval system is tested to be effective in terms of retrieval and scalability through experimental results and precision-recall analysis.

This paper proposes a seamless handoff scheme that enables a mobile node to continue a session when moving to an overlapping area. During handoff due to the weakness of signaling, mobile node makes new Care-of Addresses using signals received from access router when MN reaches the edge of its area in addition to its current CoA, and it sends temporary binding update messages to Mobility Anchor Point which manage the area covering MN. MAP receives that binding update messages from MN, and temporarily stores new binding informations from them to its binding cache besides existing binding information for MN. This scheme ensures a seamlessly handoff using multicasting until MN enter a new access router area and sends a confirmed binding update message to MAP.

Background: Many people are suffering from neck and shoulder pain due to muscle weakness, muscle fatigue, lack of exercise and accidents during exercise. In this study we compared the effects of McKenzie method and Mulligan technique method. Method: we randomly selected men(10) and women(10) and they are the 20s students of Busan material K college. We divided for McKenzie exercise group and Mulligan exercise group. McKenzie exercise and mulligan exercise applied cervical area three times a week for three weeks. We compared with pre-experiment and after 1~3 week through measuring the electromyography (EMG) change and neck range of motion (ROM). Results: The changes in the EMG at each exercise group, there was a statistically significant difference in each week. Although there was a significant difference after 1 week between the exercise group, the changes in the neck ROM at each exercise group there was no statistically significant difference. Conclusion: After experiment, EMG and neck ROM were increased in McKenzie exercise group and Mulligan exercise group. But Mulligan exercise group showed the change better than McKenzie exercise group in early stage. We suggest the Mulligan exercise method for recovering in early stage of neck ROM.

Purpose : The purpose of this study was to identify comparison of the abdominal muscle thickness and activity by using tool and unstable surface which is accompanied bridge exercise doing abdominal drawing-in breath. Method : This study was performed on normal 13 males and 17 females subjects doing bridge exercise accompanied abdominal drawing-in breath used tools. At this time muscle thickness and muscle activity is measured through ultrasound and EMG. Result : The results of this study, rectus abdominis, internal oblique and transverse abdominis showed a significant difference in muscle thickness when performed using pilates circle. And external oblique showed a significant difference muscle thickness when performed using gym ball. Rectus abdominis and external oblique showed a significant difference in muscle activity when performed using pilates circle. And internal oblique showed a significant difference in muscle activity when performed using sling. Conclusion : Therefore it is suggested that it would be effective to apply the gymball and pilates circle in the unstable surface for abdominal weakness.

오늘날 사회 전반적인 부분에서 소프트웨어의 비중은 지속적으로 증가하고 있다. 또한 소프트웨어는 점차 대규모화되고 있고 동시에 개인의 중요한 정보 등을 다루는 경우도 매우 늘어나고 있기에 소프트웨어의 보안성 검증은 매주 중요한 문제이다. 그러나 소스코드가 존재하지 않는 라이브러리의 경우 보안성 검증은 매우 어려운 문제로, 이를 해결하기 위해 바이너리 내에 존재하는 보안약점을 검사하기 위한 기술의 개발이 매우 요구되는 상황이며, 이를 위해 중간언어를 활용하여 보안약점을 분석하는 기술이 활발히 논의되고 있다. 본 논문에서는 바이너리 코드내에 존재하는 보안약점을 효과적으로 분석하기 위해서 바이너리 코드로부터 보안약점 분석에 효과적인 중간언어로 변환하는 시스템을 제안한다.
