본 논문에서는 2003년 전 세계의 인터넷망에서의 심각한 소통 장애를 일으켰던 슬래머 웜 보안공격의 전파 전과정을 NS-2를 이용한 시뮬레이터로 분석하였다. 기존 연구에서는 Detailed Network-Abstract Network(DN-AN) 모델 기반의 Abstract Network-Abstract Network(AN-AN)모델을 이용한 분석이 수행되었다. 이러한 AN-AN모델은 패킷 레벨까지 정확한 분석이 가능하지만, 초기 300초의 감염구간을 모의실험 하는데 240시간이 소요되는 시간상 문제점이 있었다. 본 논문에서는 이러한 문제점을 해결하기 위한 축소된 모델링 기법을 제시하여 모의실험에 필요한 소요시간을 단축함으로써 소통 장애가 일어난 3.5시간을 107시간에 분석할 수 있었다. 아울러 기존 분석에서는 감염 호스트가 인위적인 치료나 격리 조치가 있을 때까지는 모두 동작하는 것으로 가정하였지만, 슬래머의 과도한 감염 트래픽으로 중계 라우터의 동작이 중지되는 현상에 의해 해당 장비가 감염과정에서 자연적으로 격리되는 격리율 0.00022도 함께 고려하였다. 모의실험 결과, 국제관문국의 국외$\Longrightarrow$국내방향은 4,787초에 정상 상태로 돌아온 반면, 국내$\Longrightarrow$국외방향이 3.5시간동안 포화가 되어 소통 장애가 지속됨을 알 수 있었다.

An independent bank guarantee(aka an independent guarantee) is provided as an security on a principal obligor's performance of his obligation, and a guarantor should pay the guaranteed amount only upon a beneficiary's written demand. A standby letter of credit has been used in the United States, since it was construed that a bank should not issue a guarantee. There was wide misunderstanding that a standby letter of credit differs from an independent bank guarantee. However, a standby letter of credit is the same security as an independent bank guarantee, and in international business a standby letter of credit is not differentiated from a independent bank guarantee. An independent bank guarantee are independent from the underlying contract, unconditional, and irrevocable. And a guarantor should pay upon written demand without proving a principal obligor breaches the underlying contract. These features of an independent bank guarantee has been abused in international transactions. Thus it has been proposed that some exceptions to the features of an independent bank guarantee should be allowed. United Nations Convention on Independent Guarantees and Standby Letter of Credit(1995) stipulates some exceptions to payment obligation. Export bond insurance, a part of export insurances, operated by the Korea Export Insurance Corporation under the Export Insurance Act, is used as a security for unfair calling by a beneficiary under an independent bank guarantee. Most of the export subsides by the government are prohibited under WTO's Agreement on Subsidies and Countervailing Measures. However, as export insurance is allowed under the WTO, it operates a significant role in enhancing the export. In the event that export bond insurance is provided for a guarantor, an obligor who is subject to recourse by a guarantor, can be exempt from the recourse in case of unfair calling. The Korea Export Insurance Corporation, an insurer, bears unfair calling risk by a beneficiary. Generally it is understood that a demand shall be made before the expiry of an independent bank guarantee. However this is not absolutely true, it shall be decided by URDG, ISP98, the governing law.

The purpose of this study was to validate self care outcomes included Nursing Outcomes Classification(NOC) developed by Johnson and Maas at the University of Iowa. A sample of 103 nurse experts working in university affiliated hospitals participated in this study. They were asked to rate indicators that examplified the outcomes on a scale of 1(indicator is not at all characteristic) to 5(indicator is very characteristic). A questionnaire with an adaptation of Fehring's methodology was used to establish the content validity of outcomes. The results were as follows : 1. All indicators were considered to be 'supporting' and no indicators were considered to be 'nonsupporting'. 2. 'Self care: Toileting' attained an OCV score of 0.884 and was the highest OCV score among self care outcomes. 3. 'Self care: Oral Hygiene' attained an OCV score of 0.756 and was the lowest OCV score among self care outcomes. 4. 'Self-care: Activities of Daily Living (ADL)' attained an OCV score of 0.845 and the highest indicator was 'eating'. 5. 'Self-care: Bathing' attained an OCV score of 0.810 and the highest indicator was 'washes body'. 6.

This study aims to suggest 'an eco-friendly residential housing design guideline as an elderly housing alternative' by mixing the concept of a 'senior citizen community' housing environment with the concept of an 'eco-friendly' housing environment, based on the directivity of an elderly housing alternative for surviving in a super-aged society and the directivity of a sustainable housing environment for providing against global warming. Basically, this study considered the directivity of 'an eco-friendly residential building as an elderly housing alternative' by analyzing housing environment elements and elements to be considered in an elderly housing environment and setting the directivity of an elderly housing environment, which reflects the change in the design paradigm. In relation to the concept of universal design, for considering the perspective of elderly users, existing elements were compared and major planning elements were applied to the scope of complex planning, communal space and housing unit space. In relation to the concept of eco-friendly design, also, a guideline was re-organized and planning elements were applied to each category by comparing domestic and foreign green building certification systems. Based on domestic and foreign authorized guidelines of universal design and green building certification systems, this study was focused on suggesting an eco-friendly residential housing design guideline as an elderly housing alternative to make users perceive the need for a specific indoor environment design guideline and system.

The purpose of this study was to investigate the perceptions of an unbalanced diet by elementary school students using a qualitative approach to nutrition counseling. To achieve the purpose of this study, client-centered counseling was performed over one semester with four volunteer children in the fifth grade who admitted eating an unbalanced diet. Their perceptions of an unbalanced diet were examined while focusing on cause. The contents of the counseling sessions were recorded and their eating habits observed. The proposed perceptions of the clients of an unbalanced diet were as follows: regarding the causes of an unbalanced diet, there may have been a certain negative event or memory related to food as well as an individual disease or history of disease; regarding the meaning of an unbalanced diet, the clients had two kinds of time concepts (formal one and informal one) and defined the meaning of an unbalanced diet as a matter of being able to eat proper amounts of food within an inter-meal time; and regarding the results of an unbalanced diet, they based their results on the approval of their parents and teachers. Feeding at school was used as the background of this study, which examined the meanings and results of an unbalanced diet, and there existed a correlation between the meanings and the results.

Euibangyoochui (醫方類聚), the largest medical book in Korea, has medical and historical significance in that it had classified almost all East Asian medical accomplishments before Joseon Dynasty (1392-1910). Focusing on these values, this research investigates Yi'an (醫案), an East Asian tradition of describing clinical encounters and the therapies employed, in Euibangyoochui. By this investigation, this study expected to not only establish how the genre of Yi'an is employed for what purpose in Euibangyoochui, but also to shed a light on the appearance of Yi'an before Joseon Dynasty. At first, this study extracted Yi'an from Euibangyoochui (醫方類聚), as Yi'an does not have a standardized format. In total, the number of extracted Yi'ans is 1,025 with handwork results. Extracted Yi'ans are analyzed statically, in order to find dispersion of Yi'ans for each chapter and its references. Overall, there are 73 chapters of Euibangyoochui, which has a total of 93 chapters, containing Yi'an, while the chapter on gynecology contains the highest number of Yi'ans, 86. Judged from these result, the genre of Yi'an was used diversely and frequently, indicating various messages in Euibangyoochui. To categorize the usage and purpose of writing of Yi'ans in Euibangyoochui, this study considers some examples of Yi'ans and concludes that 3 types of Yi'ans are employed in Euibangyoochui in order to deliver the adequate medical message. One is result-centered Yi'an delivering a broader medical lesson, such as a taboo in treatment or a doctrine in medicine. The second is the concise-styled Yi'an presenting a short effective medical method. The third is multiple-information Yi'an that describes complex information of patients and medical theories, transmitting diverse lessons. Yi'ans in Euibangyoochui refer to 58 medical books. Books written by JangJaHwa (張子和; 1156-1228) are the most cited books, offering almost a quarter of total amount of Yi'ans in Euibangyoochui. This study is meaningful in that it provides basic information, such as numbers, applications, purpose of writing and references of Yi'an in Euibangyoochui. Moreover considering the historic values of Euibangyoochui, this information reflects, on the other hands, overall figures of Yi'an written before publication of Euibangyoochui.

All academic information on the web or elsewhere has its creator, that is, a subject who has created the information. The subject can be an individual, a group, or an institution, and can be a nation depending on the nature of the relevant information. Most information is composed of a title, an author, and contents. An essay which is under the academic information category has metadata including a title, an author, keyword, abstract, data about publication, place of publication, ISSN, and the like. A patent has metadata including the title, an applicant, an inventor, an attorney, IPC, number of application, and claims of the invention. Most web-based academic information services enable users to search the information by processing the meta-information. An important element is to search information by using the author field which corresponds to a personal name. This study suggests a method of efficient indexing and using the adjacent operation result ranking algorithm to which phrase search-based boosting elements are applied, and thus improving the accuracy of the search results of personal names. It also describes a method for providing the results of searching co-authors and related researchers in searching personal names. This method can be effectively applied to providing accurate and additional search results in the academic information services.
