The proportion of digital evidence in criminal cases has increased, while at the same time, the spread of the Internet has made it easy to delete information that is stored in another place and thus, the Internet is being used to delete online criminal evidence. To respond quickly and effectively to cybercrime, 29 countries signed the Convention on Cybercrime in 2001 through the Council of Europe. Article 16 of the Convention relates to the expedited preservation of stored computer data and requires signatories to adopt legislative measures to enable its competent authorities to order expeditious preservation of specified computer data where there are grounds to believe that the data is particularly vulnerable to loss or modification. More than 60 countries have joined the Convention since 2001 and have made efforts to improve their legal system in line with it. The United States legislated 18 U.S.C. § 2703(f) to preserve electronic evidence pending the issuance of a court order. The German Code of Criminal Procedure §§ 94~95 allows prosecution authorities to seize evidence or issue production orders without court control in urgent circumstances. A custodian shall be obliged to surrender evidence upon a request that evidence be preserved, and non-compliance results in punishment. Japan legislated the Criminal Procedure Act § 197(3) and (4) to establish a legal base for requesting that electronic records that are stored by an ISP not be deleted. The Korean Criminal Procedure Act § 184 outlines procedures for the preservation of evidence but does not adequately address the expeditious preservation of digital evidence that may be vulnerable to deletion. This paper analyzes nine considerations, including request subjects, requirements, and cost reimbursement to establish directions to improve the legal system for the expedited preservation of digital evidence. A new method to preserve online digital evidence in urgent cases is necessary.

The natural ecology of our coastal zone has been well preserved because of the designation of Han-Ryea national sea park. However, recently, it is being threatened by the frequent request of district regulation of national park and relaxation of green belt, etc. And also, with the reclamation of the foreshore by the development of industrial complex and tourism resource cultivation on a large scale, development pressure for natural coast is increasing. For that reason, preservation of the ecology, organized management and investigation is needed for the islands which scenery is beautiful and rare animals and plants inhabit. And also, it is worried that major habitats of migrants are diminishing because of the district regulation of national park, relaxation of green belt zone and construction of coastal streets. Therefore. on the basis of the through environmental impact assessment, only the business which are aimed at the preservation and restoration of the natural coast should be admitted and the act of eroding must be restricted.

네트워크 효율성을 개선하기 위해 CCN은 콘텐츠 제공자로부터 사용자에게 콘텐츠가 전송될 때 중간 네트워크 노드들이 전송되는 콘텐츠를 임시 저장할 수 있다고 가정한다. 또한, 네트워크 노드들이 임시 저장된 콘텐츠에 대한 요청을 수신하면, 해당 요청 메시지를 콘텐츠 제공자에게 전송하지 않고 임시 저장된 콘텐츠를 사용자들에게 전송 한다. 이와 같은 네트워킹 기술을 구현하기 위해 CCN은 계층화된 콘텐츠 이름을 이용하여 요청 메시지와 응답 메시지의 네트워크 전송 경로를 관리한다. 그러나 계층화된 콘텐츠 이름이 콘텐츠 자체에 대한 정보뿐만 아니라 도메인/제공자 정보도 의미론적으로 내포하고 있기 때문에, 콘텐츠 이름을 이용한 사용자/제공자 사생활 침해가 가능하다는 문제점을 갖고 있다. 본 논문에서는 CCN 콘텐츠 이름의 프라이버시 문제점 및 제안된 기술들을 살펴보고, 프라이버시 보호를 위한 개선된 CCN 콘텐츠 이름 관리 방안을 제안한다.

일제강점기 고건축물 보존수리 공사에 관한 공사비를 운용하는 시스템은 크게 둘로 나뉜다. 고건축물의 소유권에 따라 보존비 공사와 보존비보조공사로 구분된다. 보존비 공사는 관유 건축물, 즉 조선총독부가 소유권과 관리권을 갖는 고건축물에 대한 보존 수리를 의미하며, 보존비보조공사는 사찰 등의 개인이 소유권을 가지고 있는 사유 건축물의 보존수리를 의미한다. 관유 건축물 보존수리의 경우, 조선총독부가 주체가 되어 보존수리를 시행하였으므로 예산집행과 관리감독의 주체가 동일하다. 왕릉 및 유물, 구 관청, 향교, 일부 서원 등이 여기에 속한다. 반면 사유 건축물의 보존수리는 사유재산을 대상으로 하는 만큼 조선총독부는 보존수리의 허가에 대한 권한이 있을 뿐이다. 소유자 측에서 보존수리를 요청하면 조선총독부는 보존수리비를 지원할지 결정하고 이를 관리 감독하는 역할을 하게 된다. 사찰이 소유하는 불당 및 탑, 그리고 개인 및 문중이 소유하는 사원 및 사당이 여기에 해당한다. 따라서 관유 고건축물은 조선총독부의 예산 안에서 지출되므로 보존비 공사로 분류되고, 사유 고건축물은 조선총독부의 보존보조비 예산 안에서 지출되므로 보존비보조공사로 분류된다. 보존비공사와 보존비보조공사는 주체가 다르므로 공사시행 절차에서 다소 차이가 드러난다. 제출하는 서류의 종류, 현장감독의 역할 등 행정 절차상의 차이가 두드러진다. 이러한 양분된 시스템은 일제강점기 내내 개선되지 않은 채로 남게 된다. 조선총독부는 식민지 정부였으므로 일본 정부의 영향을 많이 받았다. 일본은 대부분의 건축 문화재가 사찰과 신사 소유였고, 관유 건축문화재가 거의 없었으므로 조선총독부와는 달리 일원화된 체제였다. 조선총독부의 고적 및 유적 관련 시스템은 당시 한국의 정황에 맞게 형성되기보다 일본의 영향 하에서 형성되었다. 따라서 문화재 보존수리 비용의 양분된 체계 속에서도 조선총독부는 뚜렷한 해결방식을 제시하지 못하였다. 이는 당시 식민지 정부인 조선총독부의 한계가 보이는 부분이라 할 수 있다.

For last century, our country fast changed by development of industry but we justly looked away that cultural and natural environment that must preserve inside the change, and we sought quantitative growth. But consciousness about culture is rising now; thereby social request becomes strong that is improved cultural environment; and viewpoint is appearing which is thought heftily cultural environment of city. Important thing of them is the modern age architecture, but serious discord is happening in the current society that allows conservation and destruction of the modern age architecture. But, visible cultural asset such as the modern age architecture is value when it protected as the first time, When it was broken! , restoration or age architecture really necessary to us.

In this work, we study the problem of privacy-preservation data publishing in moving objects databases. In particular, the trajectory of a mobile user in a plane is no longer a polyline in a two-dimensional space, instead it is a two-dimensional surface of fixed width $2A_{min}$, where $A_{min}$ defines the semi-diameter of the minimum spatial circular extent that must replace the real location of the mobile user on the XY-plane, in the anonymized (kNN) request. The desired anonymity is not achieved and the entire system becomes vulnerable to attackers, since a malicious attacker can observe that during the time, many of the neighbors' ids change, except for a small number of users. Thus, we reinforce the privacy model by clustering the mobile users according to their motion patterns in (u, ${\theta}$) plane, where u and ${\theta}$ define the velocity measure and the motion direction (angle) respectively. In this case, the anonymized (kNN) request looks up neighbors, who belong to the same cluster with the mobile requester in (u, ${\theta}$) space: Thus, we know that the trajectory of the k-anonymous mobile user is within this surface, but we do not know exactly where. We transform the surface's boundary poly-lines to dual points and we focus on the information distortion introduced by this space translation. We develop a set of efficient spatiotemporal access methods and we experimentally measure the impact of information distortion by comparing the performance results of the same spatiotemporal range queries executed on the original database and on the anonymized one.

I recognized necessity of the space planning to three-generation dwelling because of preservation of wholesome society sense of values of the younger generation indicated often to the point at issue by the change to nuclear family of present and by way to hand down thought of respect for the aged which is our traditional public morals. I wish to present basic data for storage space planning that resident's request and consciousness are reflected in such background. I investigated records in general concept, which is utilization pattern of storage space to achieve the function of these culture intermediation. The object of research is three-generation dwelling, such as 3L-K and 3L-DK as national residences that appear most generally in chongju city. The method of research was question investigation method to write utilization actual conditions and requirement of storage space directly. So I proposed suitable planning to resident's life style analyzing frequency, percentage and average distribution. When supply apartment house hereafter, it should be reflected wide selection by resident's characteristic and needed systematic storage space planning in consideration of user mainly. Also continuous and diversified researches that can improve quality of residence are required.

Background: Interest in medical malpractice claims and accidents is a day-to-day social issue to general public as well as medical personnel. Related laws and regulations already have been established, and institutions based on the laws and regulations also have been founded. However, in our dental community, interest and response to the issue seem insufficient. Methods: We searched four medical literature databases that are mainly cited in the medical community. Keywords including 'dental malpractice claims', 'patient safety' and 'medical accident' were used for the search. Among the selected literatures, we chose specific ones separately whose content is authentic and easily approachable. Results: Medical malpractice claims and accidents tend to increase around the world. As the cost or the difficulty level of surgery increases, the dispute rate also increases, which appears even more apparent in developed countries. Preventive measures to prevent the disputes and accidents are not significantly different. Three critical of them include relationship of doctor with patient, the informed consent and medical record. Conclusion: Tools for accident occurrence or communication improvement have been introduced. All of those cost time and money. However, education or professional request of liability insurance companies, self-education and provision of guidelines can be immediately implemented. To implement those, dentists' promotion at the regional or national level is imperative. rhBMP-2 is widely used at sinus augmentation, alveolar bone defect, and socket preservation.
