Objectives：Body image is closely related to self-esteem and weight-control related behaviors. In particular, relationship between two factors would be stronger in female adolescents. False recognition on body image and weight can be a risk factor of eating disorder, depression, and suicidal ideation. This study aimed to examine the effects of body image and eating disorders on developing depressive symptoms and suicidal ideation in female adolescents. Methods：Two hundred thirty nine students of a Girls' Commercial High School in Seoul were recruited. Eating Attitude Test for Korean Adolescents, Self-Esteem Scales, Impulsiveness Scale, Beck's Depression Inventory and Beck's Suicidal Ideation Scale were used to measure eating attitude and severity of psychiatric symptoms. Results：Among 239 subjects, the estimated risk group of eating disorders was 10%(n=24). They experienced more depressive symptoms than the control group. The bigger discrepancy in current and ideal body mass index was significantly related with higher depressive mood, suicidal idea, abnormal eating habits and lower self-esteem. Discrepancy between current and idea BMI was the most meaningful predictive factor about depression and suicidal thoughts by linear regression analysis. Conclusion：In spite of normal weight range of enrolled subjects, they experienced significant depressive mood, suicide thoughts and lower self-esteem associated with the discrepancy of their own subjective body image and current body mass index. Hence educational approach regarding normal body image and healthy weight control is needed for their mental health and preventing eating disorder.

본 연구는 상류의 개발행위와 더불어 현재 수질관리의 기준이 되는 오염총량관리제를 대상으로 '규모의 경제'의 논리를 따른다는 가정 하에, 지자체간에 협조를 통해 비용을 절감하여 서로 혜택을 볼 수 있도록 상 하류 지자체와 중앙정부 등 관련 당사자들 간의 비용배분 방안을 도출하는 것을 목적으로 하였다. 이를 위해서 광주광역시에 위치한 평동산업단지와 영본B, 영본C를 대상으로 광주, 전남, 중앙정부를 이해당사자로 하여 협조적 상황 하에서 대상 비용배분 문제를 정의하였고, 협조적 게임이론에 근거한 SCRB법 및 샤플리법을 적용하여 비용배분 결과를 제시하였다. 우선 광주와 전남이 각각 삭감해야 할 오염량을 산정하고, 해당 삭감량 만큼 처리하기 위한 하수처리시설의 규모를 설정하였다. 또한 하수처리시설의 건설비와 하수관거 공사비, 유지관리비를 산정하였으며, 하수처리시설의 내용연수인 20년간의 총비용을 2010년 현재가치 기준으로 산정하였다. 상 하류 지자체가 공동으로 대처할 경우 20년간 총비용은 416,311.8 백만원, 개별로 대처할 경우 464,439.6 백만원이며, 공동 대처가 42,359.3 백만원이 절감되므로 양 지자체 모두 협조적 게임에 응할 기본배경은 성립되었다. SCRB법에 의한 지자체별 비용배분율을 산정 결과, 광주 74.24%, 전남 25.76%로 산정되었으며, 2001～2010년 하수도 세입현황을 기준으로 중앙정부의 지원 비율은 10년간 최소 23.98%, 평균 29.22%, 최대 34.17%로, 각각의 비율별로 중앙정부, 광주, 전남의 비용분담액을 도출하였다. 본 논문에서는 개략적으로 비용을 산정하였으나 오염총량관리 사업은 막대한 예산을 필요로 하기 때문에 실제로 두 지자체가 협조하여 비용배분을 하게 된다면 하수처리시설의 수질개선효과, 하수처리시설 위치선정, 사업비용 등을 세밀하게 분석해야 할 것이다. 본 논문은 오염총량관리제에서 제시하는 목표수질을 대상으로 하였으나, 지자체의 정책에 따라 친수활동 증대와 생태 자연환경 개선 등과 같은 수질개선에 따른 간접적인 효과를 고려하여 오염 총량관리제의 목표수질보다 더 나은 수질을 원할 수도 있을 것이다. 협조적 게임의 상황을 복잡하게 하여 해결 가능성이 낮아질 수 있으나, 수질개선에 의한 다양한 효과를 편익으로 산정할 수 있다면 이를 협조적 게임에 적용하여 전반적인 수질개선에 대한 지자체의 적극적 활동을 유도할 수도 있을 것이다.

This paper describes intrusion detection rule management using mobile agents. Intrusion detection can be divided into anomaly detection and misuse detection. Misuse detection is best suited for reliably detecting known use patterns. Misuse detection systems can detect many or all known attack patterns, but they are of little use for as yet unknown attack methods. Therefore, the introduction of mobile agents to provide computational security by constantly moving around the Internet and propagating rules is presented as a solution to misuse detection. This work presents a new approach for detecting intrusions, in which mobile agent mechanisms are used for security rules propagation. To evaluate the proposed approach, we compared the workload data between a rules propagation method using a mobile agent and a conventional method. Also, we simulated a rules management using NS-2 (Network Simulator) with respect to time.

Urban renovation projects (reconstruction and redevelopment) have a longer licensing period than general housing projects, and many consultations with the licensing authorities require expertise. Most of the members of the union do not have basic knowledge of the maintenance business, so they have a lot of authority to promote smooth business Is entrusted to the union leader. However, contrary to the original purpose entrusted by the members, it is easy to find a case where the business is suspended because the union leader is exposed to corruption for the private interests of the union, and the members' disputes could not be resolved. In order to overcome this risk, the problem of the maintenance project was found through a questionnaire survey composed of practical experts, and a solution was presented through the KCSI evaluation model. This study mentioned the necessity of a responsible CM that can make independent business decisions without interference from the union, rather than a management-type CM limited to the cooperative's work assistance. In order to promote the construction industry's national role, it was necessary to revitalize responsible CM, so six practical alternatives were proposed.

This study was done to identify the effects of the hand washing procedure poster on the hand washing behaviors after Mers outbreak. Method: This study was conducted by observing a total of 370 people(185 people in no- poster zone, 185 people in poster zone) who used the public restroom. Results: As a result of comparing the hand washing with and without the poster, the subjects who washed their hands with the poster around were 83.2%, which was higher than the 47% of the subjects without the poster. The Time spent on the hand washing was similar between the groups with or without the poster around. Also only 3.3% of the subjects actually completed the entire 6 procedures of hand washing. The subjects who finished more than 4 procedures out of 6 were 17% from the group with the poster around, and 10.3% from the group without. Conclusion: The hand washing poster was effective in encouraging the behavior itself, but not specifically in the right way during the ideal time nor the right procedures. Therefore, verbal instructions made every time washing hands or more visual effective posters are required to enhance the hand washing procedures.

A new base expense .system is implemented to substitute the standard income ratio system which has been used for more than 50 years. A base expense system requires a rigorous documentary evidences of important expenses such as purchase cost, labour cost, or rent. In order to make a successful tax savings, it is necessary to know the critical factors affecting tax payment in a base expense system. In this article, operating mechanisms of the base expense system and tax strategy under this system are introduced. If base expense system is successfully implemented, it will contributes considerably to progress in inducing tax compliance of non book keeping professionals who earn relatively high income in Korea.

Media convergence is prevalent all over the world, and is expected to change our lives dramatically in near future. Chaos theory is a new emerging theoretical approach to various social phenomena including organization management, economic system, stock market fluctuation, and so on. This thesis is intended to explain media convergence phenomena centered on internet media using basic concepts of chaos theory such as self-organization, co-evolution, and feedback loop. The implications of this tentative study are that we can apply chaos theory to media convergence as other social or natural phenomena, and that maintaining chaos state of media system is useful for accelerating creativities, and that developing media system as an organic system to cooperate with other relevant systems is helpful for promoting life qualities, and that establishing moral order or root value is desirable for implementing communicatopia.

The recent aesthetical argument has been focusing on the interrelation between art and media. Now media is a kind of creative activity and dynamic factor which comprises aesthetic perception in itself compared to that of the past linear thingking era that was just a means of proving presence. Norbert Bolz, a leading media-aesthetician, puts the emphasis on the transformation of image, not the its dupe. He urges that this artistic form does not deliver the image of object, but means the objectless image itself. Therefore creativity is caused by an effect of a optional technic in the stage of technological environment where is under the control of the non-linear thingking system. In this context, this essay investigates to confirm the above mentioned aestheical views by analyzing the computer based layer as an detailed example, and to illuminate the designers creative activity where is deemed to be under its radical influence. Therefore it can be dedicated to the extension of the theoretical background in design, bridging between two practices accor ding to the Bolz's notion that the new aesthetical concept should be accompanied by ' the Design Science ', that is centered on the new media.

In proportion to the rapid increase in the number of Web users, web attack techniques are also getting more sophisticated. Therefore, we need not only to detect Web attack based on the log analysis but also to extract web attack events from audit information such as Web firewall, Web IDS and system logs for detecting abnormal Web behaviors. In this paper, web attack detection system was designed and implemented based on integrated web audit data for detecting diverse web attack by generating integrated log information generated from W3C form of IIS log and web firewall/IDS log. The proposed system analyzes multiple web sessions and determines its correlation between the sessions and web attack efficiently. Therefore, proposed system has advantages on extracting the latest web attack events efficiently by designing and implementing the multiple web session and log correlation analysis actively.
