The purpose of this study is to understand issues related to the Personal Information Act recently emerging in the field of oral history, and to prepare countermeasures for oral history academics and archives. The Personal Information Act is intended to protect the confidentiality and freedom of the constitutional privacy, and to assure the right to self-determination of information, thereby realizing the dignity and value of the individual. Oral history is intended for living persons; therefore, strict ethical standards are needed to protect the morality of the person behind the sound recordings and appears as the subject of oral history. However, if the uniform application of the Personal Information Act is made, it is a requirement to make the process of consenting and notifying excessively complex and almost impossible to realize, making collection and service of oral history resource improbable. The mechanical and strict application of the Personal Information Act does not come into being because it has the aspect of undermining the inherent intrinsic value of oral history resources and making it difficult to maintain the authenticity of the records. To solve these problems, it is necessary to revise Article 58 (4) of the Personal Information Act of Korea. In addition, it is necessary to establish a guideline for the establishment of independent ethical standards of oral history itself, especially for the protection of the moral rights of third parties.

Assuring the security of group communications such as tole-conference and software distribution requires a common group key be shared among the legal members in a secure manner. Especially for large groups with frequent membership change, efficient rekey mechanism is essential for scalability. One of the most popular ways to provide sealable rekey is to partition the group into several subgroups. In this paper, we propose a two-layered key management scheme which combines DEP and CBT, a protocol in which subgroup manager cannot access the multicast data and another that has a multi-core, respectively. We also select sub-group key management protocols suitable for our structure and design new rekey protocols to exclude the subgroup managers from the multicast data. Compared to previous protocols based on CBT, our scheme provides forward secrecy, backward secrecy and scalability. This would reduce the number of encryption and decryption for a rekey message and would improve the efficiency number of rekey messages and the amount of information related to group members that group managers must maintain compared to DEP.

Our society's modernization created many opportunities for us to need a private investigation service system. Variation of international environment due to joining in the OECD, opportunity of individual legal, collect evidence during judgement, prevention of damage criminal, security of business in company, free trade economy's system etc and don't need to enumerate how important of introduction of private investigation service system. In addition to there are lots of objection opinions, such as possibility of person's private life, invade of lawyer's area, confliction with investigation team, gap of wealth and poverty that make preponderance of information. So this research can be considerate from objective opinion, and can obtain conclusion just like below. First, private detective agencies that encroach on the individual rights will naturally deteriorate after the implementation of private investigation service system. Through this, the probability of civil rights encroachment will be lower, and for this to happen there needs to be a thorough maintenance of the system. Secondly, mutually beneficial solution should be found not by a conflict between two sides. Detective business sector should not cause social confusion from conflicts with other investigation organization such as police, or investigators, rather, it must get on the demand of the diversified citizen and maintain the diverse sector inter-cooperate right, and to do that law and institution must be made for the base. Thirdly, investigation used depending on the gap between wealth and poverty does not mean the actualization of the rights and interests of the citizen. If the duty of investigation sector is to find the evidence and collect or manufacture of the evidence, then the problems which the nation can't handle will be more enlarged and then finally end up with strengthening the capability of national public security demand.

Recently China's science and technology development is accelerating, and some technologies have the world's best technology. With the rapid development of science and technology, China has been deeply aware of the importance of science and technology, and many efforts are being made to legislate security regulations to protect their technologies. Korea and other countries are also interested in research security, and research and development cooperation with China is also on the rise. In this paper, we derived some implications by comparing and analyzing China's science and technology security regulation and Korea's national R&D project management regulations. China is also enacting science and technology security regulations as a subordinate to the laws and regulations of science and technology. However, it should be reflected in future legislation that the difference from Korea is composed of separate independent regulations. In particular, the fact that the science and technology security regulations have been enacted separately may be a hint that can be reflected in the nation's future legislation processes. In this paper, major contents of the science and technology security regulations, points to division of knowledge property into scientific and technological cooperation or security tasks, designation of regulations on the characteristics of research security guidelines, and operation of individual national security agencies In addition, in the event that the contents of the related statutes, confidentiality provisions, and import and import control are recorded in this paper, and the results of the joint R&D project are not utilized, or the technology transfer is not carried out.

Existing Wi-Fi networks require users to follow network settings of the AP (Access Point), resulting in inconveniences for users, and the password of the AP is shared by all users connected to the AP, causing security information leaks as time goes by. We propose, in this work, a personalized secure Wi-Fi network, in which each user is assigned her own virtual Wi-Fi network. One virtual Wi-Fi per user makes the user-centric network configuration possible. A user sets a pair of her own SSID and password on her device a priori, and the AP publishes its public key in a suitable way. The AP also maintains an open Wi-Fi channel, to which users can connect anytime. On user's request, the user device sends a connection request message containing a pair of SSID and password encrypted with the AP's public key. Receiving the connection request message, the AP instantiates a new virtual AP secured with the pair of SSID and password, which is dedicated to that single user device. This virtual network is securer because the password is not shared among users. It is more convenient because the network adapts itself to the user device. Experiments show that these advantages are obtained with negligible degradation in the throughput performance.

As pervious the SAR(Security Aware Routing)[10] protocol is an secure Ad Hoc network protocol that finds a secure path, it is the security routing protocol that uses the security level of nodes as the routing information. However, the SAR protocol sometimes transfers data through inefficient transmission paths because it always tries to find secure nodes for a safe transmission. Since it is a protocol based on AODV[6], it will cause transmission delay as researching of security routing path. when a node is out of the data transmission range as its battery dying or movement. Although it is possible to connection of nodes because a characteristic of the SAR protocol, the connection is not easy to reconnect when the security level of intermediate node is lower than the level requested by a source node. In this paper, we suggest the MP-SAR based on the SAR to solve the SAR protocol's problem. The MP-SAR seeks multiple secure path for maintenance of data confidentiality using the expanded secure path detection techniques based on the SAR. It can transfer data quickly and reliably by using the shortest efficient path among multiple paths. In the research result, we proved a outstanding performance of MP-SAR than the previous SAR through comparison and analysis.

The Korean Peninsula is put in a position to carry out a highly strategic game vis-a-vis nK, which is asserting itself as a nuclear power amongst Northeast Asia's complex dynamics. While the international community recognizes nK's possession of nuclear weapons as released secret based on nK's three nuclear tests, shrewd strategic thinking is needed by ROK to secure itself as a non-nuclear nation in order to assume a responsible role to the international community, while simultaneously being ready to respond at all times for nK's military provocations. ROK must continue with its twofold strategy, by firm response to military confrontation with nK and maintaining flexible policy of tolerance in the areas of economy and ethnicity. Various strategic options to overcome nK's nuclear threats have been presented to ROK, whose possession of nuclear weapons have been difficult, and nK's nuclear capability is a real threat to ROK's national security. We must be able to respond to nK's nuclear threats strictly from ROK's national security perspective. This thesis aims to propose a response policy for nK's nuclear capability and nK's nuclear attack based on analysis of such nuclear damage, ROK Government's response posture against nK's nuclear threats, centered around ROK Government's non-military response posture.

Of recent interests on high capacity DNA storage, DNA watermarking for DNA copyright protection, and DNA steganography for DNA secret communication are augmented, the reversible DNA watermarking is much needed both to embed the watermark without changing the functionality of organism and to perfectly recover the host DNA sequence. In this paper, we address two ways of DE based reversible DNA watermarking using noncoding DNA sequence. The reversible DNA watermarking should consider the string structure of a DNA sequence, the organism functionality, the perfect recovery, and the high embedding capacity. We convert the string sequence of four characters in noncoding region to the decimal coded values and embed the watermark bit into coded values by two ways; DE based multiple bits embedding (DE-MBE) using pairs of neighbor coded values and consecutive DE-MBE (C-DE-MBE). Two ways process the comparison searching to prevent the false start codon that produces false coding region. Experimental results verified that our ways have more high embedding capacity than conventional methods and produce no false start codon and recover perfectly the host sequence without the reference sequence. Especially C-DE-MBE can embed more high two times than DE-MBE.

This study set out to investigate the adaptation process and experiential structure of those children who went through sexual abuse by looking into their inner worlds in order to understand what kind of meaning sexual abuse had on them. For that, the investigator conducted in-depth interviews with 13 children aged 8~16 who lived at the shelter after experiencing sexual abuse. The methodology of Grounded Theory by Strauss and Corbin(1990) was used to analyze raw data. The analysis results indicate that the core theme of the adaptation process among the children living at the shelter after sexually abused by kin and kith was "hoping to appear the same as others." According to the results, the core phenomenon was "blaming the victims." The causal conditions include "broken families," "antihuman sexual abuse," "making sexual abuse a public issue," and "the trap of the family." The contextual conditions include "the chain named family," "family as the last fortress" and "structural enforcement of silence." The intervening strategies was "dual emotions toward the shelter." The action/interaction strategies include "aftermath of violence" and "trying to escape." The consequences were "preparation for the future" and "uncertain future." The identified stages include the confusion, keeping the secret, leaking the secret to others, intervention by others, social support and challenge and adjustment stage. The three identified types were "withdrawal and avoidance," "settling down in reality" and "overcoming and challenging." Based on the analysis results, discussions were made about the social welfare plans and intervention strategies in the conclusion.

Three frequently used documents by researchers on the Japanese colonial period-Classified Police Records of the Japanese Government-General of korea on the Anti-Japanese Movement 舊 朝鮮總督府 警務局 抗日獨立運 動關係 秘密記錄, Trial Records of Gyeongseong District Court 京城地方法院 裁判記錄 and Filed Documents of Gyeongseong District Court 京城地方法院 編綴文書(while the latter two were collected by the National Institute of Korean History, the former was collected by Asiatic Research Institute of Korea University)-are among the same records group that the Prosecutor's Office of Gyeongseong District Court produced through registration and compilation. As contents related to ideology suppression and thought control were numerous, it could be assumed that most of the materials were produced by the 'Department of Ideology' of the Prosecutor's Office. By examining the administrative records of the 1920's within this group, the process of how the 'Department of Ideology' was formed is clearly shown. As ideological movements for Korea's independence and revolution grew, execution of regulations was further expanded by the Prosecutor's Office. Since the mid-1920's, information on ideology had been separated from general information, was routinely collected heavily, and was considered more valuable than the general information. By the end of the 1920's, the term Ideology Prosecutor 思想係 檢事(meaning a prosecutor who specializes in ideology verification) and the named 'Department of Ideology'(思想部) emerged on the records.
