가격대 성능비가 우수한 클러스터 시스템의 보급이 확산되어 많이 사용되고 있다. 클러스터 시스템을 구성하는 컴포넌트들은 다양한 이벤트를 발생시키고 통지하는 상호작용을 하기 때문에 시스템을 효과적으로 관리하기 위해서는 이벤트를 직접 또는 간접적으로 통지해 주는 이벤트 통지 서비스가 필요하다. 본 논문은 클러스터 환경에서 컴포넌트들 간에 발생하는 이벤트를 직접적으로 통지하는 이벤트 통지 서비스를 제안한다. 이 이벤트 통지 서비스는 컴포넌트들 간에 발생한 이벤트를 직접적으로 통지하기 때문에 전송속도가 빠르며, 통지 시 필요에 따라 다양한 이벤트 핸들링 모듈을 적용할 수 있는 유연한 구조로 설계되었다. 또한, 신뢰성 있는 통신을 위하여 UDP를 확장한 하부 데이터 통신 인프라를 사용하였다.

Recent personal data breach incidences draw the public's attention to their privacy and personal rights. The new personal data protection law effective in September 2009 imposes additional legal responsibility on personal data controllers and processors. For instance, if a data breach occurs, this new law requires that the processors must notify individuals (data subjects) and data protection authorities of the nature of incidents. This research reviews the U.S. forty six state laws and related acts, and offers a framework for managing incidents. This framework includes five major components: (1) type of personal data required to be reported and notified, (2) the ultimate subject notifying data subjects, (3) event occurrence and notification time phases, (4) notification message details, and (5) direct/indirect communication media. Along with this framework, we also offer directions for effective/manageable guidelines on data breach notification act.

Smart phones can be used in parking management to receive important notifications. An infrastructure based from such approach should consider message persistence which is currently supported through push notification systems. However, the broadcast method produces high overhead when sending notifications throughout the clients. This paper uses a filtering method to prevent unnecessary message overheads. The heuristic approach selects the mobile clients with corresponding preference values based on the notification tag values. The simulation result showed that the proposed filtering method was faster in re-establishing connections and had lower message overhead compared to conventional messaging frameworks.

The objective of this study is to examine the tasks for listing martial arts of "Muyedobotongji" on the UNESCO Representative List of Intangible Cultural Heritage of Humanity. The conclusions are like below. First, "Muyedobotongji" was published in 1790(14th year of King Jeongjo). The 24 martial arts of "Muyedobotongji" were basically divided into three types like stabbing, chopping & cutting, and hitting. Second, the value of martial arts of "Muyedobotongji" is highly evaluated because it has systematically put together the martial arts of three countries like Korea, China, and Japan of the 18th century, suitable for the actual status of Joseon Dynasty, in the new perspective. The value of "Muyedobotongji" as a Memory of the World is the martial arts book emphasizing the practicality, so that everyone including officers and soldiers could easily learn. Third, the procedure of registering martial arts of "Muyedobotongji" in the UNESCO Representative List of Intangible Cultural Heritage of Humanity has three stages including preparation/submission, screening, and decision, which takes two years. Especially, the screening assistance organization, as an organization under the Intangible Cultural Heritage Convention Intergovernmental Committee is composed of total six countries(one for each area) out of 24 member countries. Fourth, the tasks for listing martial arts of "Muyedobotongji" in the UNESCO Representative List of Intangible Cultural Heritage of Humanity are like following. (1) It would be necessary to conduct a total inspection of the collection of "Muyedobotongji". (2) It would be necessary to designate the martial arts of "Muyedobotongji" as the municipal/provincial/national intangible cultural heritage. (3) It would be needed to standardize the practical martial arts technique/movement of "Muyedobotongji". (4) The historical evidence of martial arts costumes/weapons of "Muyedobotongji" should be studied. (5) A committee for the registration of martial arts of "Muyedobotongji" in the UNESCO Representative List of Intangible Cultural Heritage of Humanity should be organized. (6) There should be a close cooperation system between relevant departments like the World Heritage Team of Cultural Heritage Administration and the Ministry of Foreign Affairs. (7) Domestic/foreign data related to martial arts of "Muyedobotongji" should be comprehensively collected to meet the registration standard of UNESCO. (8) The registration type of Intangible Cultural Heritage of Humanity should be prepared.

One of the challenging tasks of the National Health Insurance Corporation(NHIC). the only public insurance institution administrating the Korea's compulsory national health insurance(NHI) system, is to make those NHI beneficiaries who fail to make a scheduled monthly premium payment to pay. For this purpose, the NHIC has been using a measure known as 'Benefit Limit Measure(BLM)' in which those who miss premium payment for six or more month's in total are classified as 'late payer' and are sent warnings and late payer status notices. If the late payers fail to make a full payment of missed premiums even after receiving the written notices, the NHIC can order a temporary seizure of the late payer's property until all missed premiums plus interest are paid. Recently, the BLM has been criticized by the public of its cruel nature, and its effectiveness has been questioned because no empirical evidence has been collected. In this study, the authors using the NHIC data set attempted to analyze the effectiveness of the BLM. Those late payers for whom the BLM was administered were compared to those not in terms of the likelihood of paying missed premium payments with a series of logistic regression analyses models. Data analyses results showed that the likelihood of paying one or more month's unpaid premium of the former group was 14 to 46 times higher than the latter. It, however, was also found that the BLM was only effective to make no more than 12% of the late payers to pay at all. Based on the study findings, the authors made a few recommendations regarding the BLM.
