Korea's traditional hanok houses are roughly divided into tiled-roofed, thatched-roofed, shingle-roofed, and oak bark-roofed houses according to their materials. In thatched-roof houses, there are various styles according to regional characteristics regarding building materials, slope, shape, and tying method. Unfortunately, as the number of thatched-roof houses have been rapidly decreasing since industrialization, it is difficult to find these characteristics of traditional houses. The study revealed that there was a roofing material a higher percentage of houses with thatched roofs than houses with tiled roofs. Furthermore, the plane occupies a large number of left and right protruding types and layered types, and there is no partition wall between Jeongji and maru. In addition, the opening in the front has characteristics of the Northern region that is responsible for lighting and ventilation, not for access. In the case of thatched-roof houses in Goseong Wanggok Village, the field survey suggests that a high percentage of buildings can recover their original characteristics.

International construction contractors are often faced with the situation of working in an unfamiliar construction environment. Under FIDIC rules, the contractor has the right to make a claim requesting the consulting engineer for an adjustment to the contract price or the time for completion when a part or parts of the works have changed, or in the event of unforeseeable conditions. Contractors generally have more access to the costs and time implications of such a change or unforeseeable conditions than the consulting engineer or outside neutrals. Due to such an asymmetry of information, the contractor may be motivated to dispute frivolous claims of less merit, expecting erroneous judgments by the consulting engineer or the neutrals. In this paper, a claiming behavior model is presented by using game theory and experience data to study the manner in which frivolous claims develop into disputes. The model also analyzes the impacts of DAB/DRB upon the frivolous claims.

The aim of this study was to assist the development of parenting-aid policies by analyzing information from life perspectives, family system theory, and integrated family policy perspectives. For this purpose, we conducted a literature using a variety of sources including internet sites, laws, published material related to current parenting-aid policies. Based on analyses we formulated four agendas: empowering parent competency, supporting diverse family parenting, guaranteeing parent's rights, and supporting parenting of dual-income families parenting. The results were as follow: Firstly, for empowering parent competency, we proposed the development of family relationship empowerment programs including family life cycle and children-raising support services. Secondly, for diverse family parenting, we proposed access to integrated parenting-aid programs dependent on family types. Thirdly, for guaranteeing parent’s rights, we proposed the supporting of child raising costs and tax returns to families with children, and provide child allowances. Finally, for dual-income family parenting, we proposed that schools and communities must recognize that dual-income families are a universal family type, establish family friendly business culture, and to develop a more democratic domestic family-relationship. This policy proposed a new paradigm where parents must be recognized as partners and stakeholder in development of family related policies. Ultimately, such policies will contribute to increased birth rate and development of a more respectful society.

With widespread use of the Internet and improvements in streaming media and compression technology, digital music, video, and image can be distributed instantaneously across the Internet to end-users. However, most conventional Digital Right Management are often not secure and not fast enough to process the vast amount of data generated by the multimedia applications to meet the real-time constraints. The SVC offers temporal, spatial, and SNR scalability to varying network bandwidth and different application needs. Meanwhile, for many multimedia services, security is an important component to restrict unauthorized content access and distribution. This suggests the need for new cryptography system implementations that can operate at SVC. In this paper, we propose a new scrambling encryption for reserving the characteristic of scalability in MPEG4-SVC. In the base layer, the proposed algorithm is applied and performed the selective scambling. And it encrypts various MVS and intra-mode scrambling in the enhancement layer. In the decryption, it decrypts each encrypted layers by using another encrypted keys. Throughout the experimental results, the proposed algorithms have low complexity in encryption and the robustness of communication errors.

In order to assure universal information access right, the present regional gap of public library infrastructure needs to be examined in Korea. The purpose of this study is to propose an effective government financial support policy to local government to bridge the regional gaps among 16 Korean wide autonomous communities. For that purpose, this study analyzed some of the per library and per capita measures, surface areas, number of librarians, number of books, total budgets and budgets for materials, etc, available in the National Library Statistics System. Then, this study reviewed changes and problems in new government financial support systems which started from 2010. Based on the results, a reformation plan of the current government financial system to national subsidy program was proposed.

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.

In this paper, we proposed the digital contents distribution business model for the operation of integration between heterogeneous systems in order to use IPTV. Also, we designed and implemented the protection management system through this distribution business model. This proposed model maintains interoperability between the heterogeneous systems, creates rights protection document based on REL, and provides the new version of packaged digital contents to itself by packaging the digital contents. Overall, it ultimately offers an interoperable environment. Moreover, since we pre-defines the relations among REL data based on MPEG-21 standard, which creates the newly packaged digital contents, it is easy to edit data. We can expect to save expenses of digital contents distribution and rights protection technology. Additionally, we can further improve security by encapsulating the security technology of CAS and DRM system.

Cloud computing is becoming an effective and efficient way of computing resources and computing service integration. Through centralized management of resources and services, cloud computing delivers hosted services over the internet, such that access to shared hardware, software, applications, information, and all resources is elastically provided to the consumer on-demand. The main enabling technology for cloud computing is virtualization. Virtualization software creates a temporarily simulated or extended version of computing and network resources. The objectives of virtualization are as follows: first, to fully utilize the shared resources by applying partitioning and time-sharing; second, to centralize resource management; third, to enhance cloud data center agility and provide the required scalability and elasticity for on-demand capabilities; fourth, to improve testing and running software diagnostics on different operating platforms; and fifth, to improve the portability of applications and workload migration capabilities. One of the key features of cloud computing is elasticity. It enables users to create and remove virtual computing resources dynamically according to the changing demand, but it is not easy to make a decision regarding the right amount of resources. Indeed, proper provisioning of the resources to applications is an important issue in IaaS cloud computing. Most web applications encounter large and fluctuating task requests. In predictable situations, the resources can be provisioned in advance through capacity planning techniques. But in case of unplanned and spike requests, it would be desirable to automatically scale the resources, called auto-scaling, which adjusts the resources allocated to applications based on its need at any given time. This would free the user from the burden of deciding how many resources are necessary each time. In this work, we propose an analytical and efficient VM-level scaling scheme by modeling each VM in a data center as an M/M/1 processor sharing queue. Our proposed VM-level scaling scheme is validated via a numerical experiment.

This study is to propose the philosophical direction of public library services based on human rights. To accomplish this purpose, this study comparatively analyzed key concepts from 13 statements related to IFLA as well as UDHR with the inductive approach for qualitative data analysis. The result shows that the most important concepts of human right emphasized from IFLA statements are 1) UDHR Article 19: Freedom of opinion and expression, and Freedom of information access, 2) Article 2: No distinction of any kind, Article 12: Privacy, and Article 26: Education, 3) Article 18: Freedom of thoughts, conscience and religion, and Article 27: Cultural life. From this result, this study finally suggests that the concept of human rights should be added to the Korean Library Law.

Purpose: Continuous intravenous access is imperative in emergency situations. Ultrasound-guided internal jugular vein (IJV) catheterization was investigated in critically ill pediatric patients to assess the feasibility of the procedure. Methods: Patients admitted to the pediatric intensive care unit between February 2011 and September 2012 were enrolled in this study. All patients received a central venous catheter from attending house staff under ultrasound guidance. Outcome measures included successful insertion of the catheter, cannulation time, number of cannulation attempts, and number and type of resulting complications. Results: Forty-one central venous catheters (93.2%) were successfully inserted into 44 patients (21 males and 23 females; mean age, $6.54{\pm}1.06$ years). Thirty-three patients (75.0%) had neurological disorders. The right IJV was used for catheter insertion in 34 cases (82.9%). The mean number of cannulation attempts and the mean cannulation time was $1.57{\pm}0.34$ and $14.07{\pm}1.91$ minutes, respectively, the mean catheter dwell time was $14.73{\pm}2.5$ days. Accidental catheter removal was observed in 9 patients (22.0%). Six patients (13.6%) reported complications, the most serious being catheter-related sepsis, which affected 1 patient (2.3%). Other complications included 2 reported cases of catheter malposition (4.6%), and 1 case each of arterial puncture (2.3%), pneumothorax (2.3%), and skin infection (2.3%). Conclusion: The results suggest that ultrasound-guided IJV catheterization can be performed easily and without any serious complications in pediatric patients, even when performed by visiting house staff. Therefore, ultrasound-guided IJV catheterization is strongly recommended for critically ill pediatric patients.
