Appropriate prescription writing is one of the critical medical processes affecting the quality of public health care. However, this is a complex task for newly qualified intern doctors because of its complex characteristics requiring sufficient knowledge of medications and principles of clinical pharmacology, skills of diagnosis and communication, and critical judgment. This study aims to gather data on the current status of undergraduate prescribing education in South Korea. Two surveys were administered in this study: survey A to 26 medical schools in South Korea to gather information on the status of undergraduate education in clinical pharmacology; and survey B to 244 intern doctors in large hospitals to gather their opinions regarding prescribing education and ability. In survey A, half of the responding institutions provided prescribing education via various formats of classes over two curriculums including lecture, applied practice, group discussions, computer-utilized training, and workshops. In survey B, we found that intern doctors have the least confidence when prescribing drugs for special patient populations, especially pregnant women. These intern doctors believed that a case-based practical training or group discussion class would be an effective approach to supplement their prescribing education concurrently or after the clerkship in medical schools or right before starting intern training with a core drug list. The results of the present study may help instructors in charge of prescribing education when communicating and cooperating with each other to improve undergraduate prescribing education and the quality of national medical care.

The accident of Sewol Ferry is a disaster that provoked serious mental shock to the Korean people way beyond the level of generally-perceived catastrophic aftermaths. The purpose of this study is to examine the relationship between vicarious disaster experiences through media and post-traumatic stress(PTSD) symptoms of media users related to the accident. The responses of 417 people consisted of college, middle and high school students, and adults in a metropolitan area were collected for 12 days from the April 28, 2014 right after the accident. The results showed that the level of PTSD of social media users were higher than that of traditional media (newspapers or TV news) users on the accident. Also, the amount of use of disaster news information and social media revealed positive correlations with PTSD. Implications of this study are to demonstrate possible mechanisms of psychological trauma mediated by media on a disaster and its empirical data and to facilitate further research.

Since, Davis(1991) has proposed the TAM(Technology Acceptance Model) through a literature review of informatization promotion, which insists that a user conveniency is judged by the degree of effectiveness caused by IT, the advancement of IT such as the Internet, e-mail, electronic data exchange, and groupware have brought into various changes in ordinary corporations and public institutions. However, with the right function, the advancement of IT has provided various benefits including additional reverse functions. Based on an integrated environment of business process, unauthorized user could access to information and a management of information becomes more difficult than before due to informatization of critical information. Furthermore, external hacking or information leakage by insider becomes easier owing to advancement in communication technology. This study has tried to develop a specified management procedure and implementation method for confidential documents.

This paper describes a design of scalable RSA public-key cryptography processor supporting four key lengths of 512/1,024/2,048/3,072 bits. The modular multiplier that is a core arithmetic block for RSA crypto-system was designed with 32-bit datapath, which is based on the CIOS (Coarsely Integrated Operand Scanning) Montgomery modular multiplication algorithm. The modular exponentiation was implemented by using L-R binary exponentiation algorithm. The scalable RSA crypto-processor was verified by FPGA implementation using Virtex-5 device, and it takes 456,051/3,496347/26,011,947/88,112,770 clock cycles for RSA computation for the key lengths of 512/1,024/2,048/3,072 bits. The RSA crypto-processor synthesized with a $0.18{\mu}m$ CMOS cell library occupies 10,672 gate equivalent (GE) and a memory bank of $6{\times}3,072$ bits. The estimated maximum clock frequency is 147 MHz, and the RSA decryption takes 3.1/23.8/177/599.4 msec for key lengths of 512/1,024/2,048/3,072 bits.

A design file can get larger in size as the complexity of the target object increases. A large design file may reside in a large parallel computing system, such as cloud computing systems, and many designers may work concurrently on the same design file. In such a case, it is obvious that we need some kind of protection mechanism so that each user can access only the area of the file he or she is entitled to. Two approaches can be taken for this problem: one is the traditional access control mechanisms and the other encryption techniques. We take the latter approach to ensure the safety of the file even in public domain such as clouding systems, and in this paper, we suggest an encryption scheme for a file where the file is encrypted in multi-layer so that each user is allowed to access the file only at the layer for which the user has the proper access right. Each layer of the file is encrypted with different keys and these keys are exposed only to those who have the right access permit. The paper explains the necessary file format to achieve this goal and discusses the file manipulation functions to handle this new file format.

The purpose of this study is to investigate typical ethical problems found in the technical and public services areas. The followings are the summary of the study. There are three distinct elements that govern ethical problems. One element is legal laws. The copyright law and the privacy act are exact examples. The copyright law has strong influence on the inter library loan service where the majority requests from the users are reproduction of copies. The privacy act also creates difficulties for librarians. Most requests for circulation records infringe on the privacy of library user. And advance online access systems also violates the privacy of library users. The second element is the code or rules that private organization has created. American Library Association created many statements that regulate the conduct of librarians. The bill of right, the professional code of ethics and policy on the confidentiality of library records have strong implications in the obligation of librarian. In the case of censorship at the selection of library materials, the code is a defensive tool against intellectual freedom. Yet self-censoring are prevailing practice among librarians. The thirds element is the competence of librarians. The analyzed table 3 showed that beside two elements, the rest of matters are competence required by librarians. The one aspect of it is humaneness and the other one is technical aspects. Technical aspect of competence are:(l) managerial and operational ability (2) communication skill (3) leadership (4) structure of knowledge and (5) self developing professionalism. Humanity aspect of competence are:(l) trust(fiduciary relationship) gained by diligence, objective judgement, ability, belief, rationality, integrity, kindness) (2) objectiveness (free from bias) (3) user-oriented consideration (need, interest, equal treatment, information gap) (4) caution in providing information (5) pride and (6) ability to distinguish advice and guidance specially in medical and law library.

The UAV(Unmanned Aerial Vehicle, Drone) technology has been undergoing rapid progress, accompanied with a growth in the market. However, domestic industry standards and technology lag behind such progress happening on the international scene, and in particular in developed countries. Related regulations are also deemed lacking to address the issues that arise with such developments. Meanwhile, as the rise of UAV technology is a fairly recent phenomenon, the gap between Korea and developed countries is not too big. As this technology has high relevance to information and communication technologies, it also offers ample leeway for Korea to catch up in the field of UAV. As such, this paper seeks to provide a survey of the overall technology, market and regulations concerning UAV to identify possible measures on how to address any issues that may arise through proper policies. Due to the progress made in the field of UAV technology and increased penetration rate, striking a right balance between putting in place a proper regulatory system and establishing policies that foster growth in the field has risen as a very important issue. While the importance of establishing a legal system that helps prevent possible risks is indeed important, it must also be acknowledged that excessive regulation can also hinder technological progress. This, in turn would stagnate the market and dampen the entrepreneurial spirit in the society. In the case of new, practical technologies such as UAV, a prompt establishment of regulatory systems and policy measures in terms of policies is a requisite. In brief, in order to promote progress in the UAV industry and at the same time, for public safety and the protection of privacy, there should be an appropriate level on the easing and tightening of the regulation.

Steganography is being used as a means of secret communication for crimes that threaten national security such as terrorism and espionage. With the development of computers, steganography technologies develop and criminals produce and use their own programs. However, the research for steganography is not active because detailed information on national security cases is not disclosed. The development of investigation technologies and the responses of criminal law are insufficient. Therefore, in this paper, the detection and decoding process was examined for steganography investigation, and the method was analyzed for 'the spy case of Pastor Kim', who was convicted by the Supreme Court. Multiple security devices were prepared using symmetric steganography using the pre-promised stego key. Furthermore, the three criminal legal issues: (1) the relevance issue, (2) the right to participate, and (3) the public trial issue a countermeasure were considered in national security cases. Through this paper, we hope that the investigative agency will develop analysis techniques for steganography.

Standing to sue has become one of the most important and controversial issues in suits between the press and the victims injured by the press reports. Even thought Korean law was patterned after the European legal system, there is no denying that the Korean Constitution was influenced by that of the United States. The judicial system was also influenced by its counterpart in the United States. The doctrine of standing to sue has plagued the U.S. Supreme Court for several decades. The traditional test of standing in the federal courts was, at the beginning of the century, whether the interest asserted by the plaintiff amounted to a 'legal right', entitled to the protection of the common law. In recent years, the Supreme Court seems to have settled on a two-tiered method for determining whether a plaintiff has standing to sue in federal court. The first level of inquiry is the constitutional core, and the second is the judicially imposed prudential limitations. The purpose of this study is to find out the doctrine of standing in the legal proceedings caused by the press reports. The press needs to internally transform as well to prevent legal dispute, enforcing confirmation when collecting news materials and building up the device for pre-examining the news. The press is also requested to help sincerely the victim recover, realizing that they waste their reputation and credit not to mention a lot of time and monet during the legal dispute.

The purpose of this study is to analyze the development progress of Pacific Park (formerly Atlantic Yard) in Brooklyn, New York City. Along with the Hudson Yards Development in Manhattan, Pacific Park is one of New York City's leading large-scale urban development projects using space right above an existing railway and has attracted worldwide attention. With the resurgence of large-scale development, its advanced form has received social attention. In particular, the development was evaluated as an exemplary development using the Community Benefits Agreement, which benefits local residents. Unfortunately, due to various difficulties, the development has been struggling from delays and changes away from the early stages, which have also caused social concerns and criticism. In this regard, this study examines the development through the process and the public sector's responses to the risk-inducing factors and reactions. The theoretical background of the US urban redevelopment is examined, and the specific changes and major contents of the project are analyzed. The following implications were drawn based on changes and responses in the development process: 1) securing the flexibility and mandatoryness of developers, 2) comprehensive control of the development site, 3) communication with and responding to the public, 4) securing additional financial resources, and 5) verification of new technologies.
