The illegal copying and redistribution of digitally-stored information is a crucial problem to distributors who electronically sell digital data. fingerprinting scheme is a technique which supports copyright protection to track redistributors of electronic information using cryptographic techniques. Anonymous asymmetric fingerprinting scheme prevents the merchant from framing a buyer by making the fingerprinted version known to the buyer only. And this scheme allows the buyer to purchase goods without revealing her identity to the seller. In this paper, a new anonymous asymmetric fingerprinting scheme with TTP is introduced. The buyer's fingerprint is generated by the Fingerprint Certificate Authority which is a TTP. When the seller embeds the fingerprint in the digital data, the protocol uses the homomorphic encryption scheme. Thus the seller cannot know the buyer's fingerprint and the buyer's anonymity is guaranteed by using anonymous key pair.

The reliability or the safety index is a measure of how far a structure is from the state of collapse. Also it defined as the probability that a structure will not fail in its lifetime. Having any increase in the reliability index is typically interpreted as increasing in the safety of structures. On the other hand most of researchers acknowledged that one of the most effective means of increasing both the reliability and the safety of structures is to increase the structural redundancy. They also acknowledged that increasing the number of vertical seismic framing will make structural system more reliable and safer against stochastic events such as earthquakes. In this paper the reliability index and the behavior factor of a numbers of three dimensional RC moment resisting frames with the same story area, equal lateral resistant as well as different redundancy has been evaluated numerically using both deterministic and probabilistic approaches. Study on the reliability index and the behavior factor in the case study models of this research illustrated that the changes of these two factors do not have always the same manner due to the increasing of the structural redundancy. In some cases, structures with larger reliability index have smaller behavior factor. Also assuming the same ultimate lateral resistance of structures which causes an increase to a certain level of redundancy can enhance behavior factor of structures. However any further increase in the redundancy of that certain level might decrease the behavior factor. Furthermore, the results of this study illustrate that concerning any increase in the structural redundancy will make the reliability index of structure to be larger.

Recent seismic events occurred in Italy (Emilia-Romagna 2012, Abruzzo 2009) and worldwide (New Zealand 2010 and 2011) highlighted some of the weaknesses of precast concrete industrial buildings, especially those related to the connecting systems traditionally employed to fasten the cladding panels to the internal framing. In fact, one of the most commons fails it is possible to observe in such structural typologies is related to the out-of-plane collapse of the external walls due to the unsatisfactory behaviour of the connectors used to join the panels to the perimeter beams. In this work, the strengthening of a traditional industrial building, assumed as a case study, made by precast reinforced concrete is proposed by the adoption of a dual system allowing the reinforcement of the structure by acting both internally; by pendular columns and, externally, on the walls. In particular, traditional connections at the top of the walls are substituted by devices able to work as a slider with vertical axis while, the bottom of the walls is equipped with two or more hysteretic dampers working on the uplift of the cladding panels occurring under seismic actions. By means of this approach, the structure is stiffened; obtaining a reduction of the lateral drifts under serviceability limit states. In addition, its seismic behaviour is improved due to the additional source of energy dissipation represented by the dampers located at the base of the walls. The effectiveness of the suggested retrofitting approach has been checked by comparing the performance of the retrofitted structure with those of the structure unreinforced by means of both pushover and Incremental Dynamic Analyses (IDA) in terms of behaviour factor, assumed as a measure of the ductility capacity of the structure.

Domestic broadcasting companies are obliged to provide the disaster information quickly to protect the public from the disaster, and people can prepare the disaster. Especially, Korea Broadcasting System (KBS) has a duty to deliver disaster news more quickly and accurately than other broadcasting companies because it is designated as a host broadcaster for disaster broadcasting services in accordance with Article 43 of the Broadcasting Act. This study examined how the KBS deals with social disaster news related to Zika virus, and evaluated whether they used the frames in a timely manner to help people prepare a disaster. Based on the results of this analysis, this study tried to suggest practical implications for measures to improve the efficiency and reliability of disaster news report.

This study critically reviewed whether the South Korean press reported the issue of conflict between South Korea and Japan in a way consistent with their journalistic values. To this end, this study conducted frame analysis and textual analysis for the articles of three press(Chosun Ilbo, Hankyoreh and KBS) from the three major branches of conflict (Korea's Supreme Court's ruling on forced labor compensation in October 2018, the Japanese government's decision to regulate exports in July 2019 and the Korean government's decision to end GSOMIA in August 2019) to one week. There were many superficial reports of simply relaying conflicts around the occurrence and outcome of events, and there were few reports that analyzed the context in depth or suggested alternatives. And partisan reporting, which is cited as a key issue in the Korean journalism, has been strongly revealed in the midst of a conflict between Korea and Japan, a national emergency situation.

This research analyzed domestic newspapers' agenda setting trend and meaning construction process on the issue of marine environment by year. The research conducted a language network analysis and used R program and Netminer program to analyze four major daily newspapers' news coverages (Dong-A, Joongang, Hanhyoreh, and Kyunghyang) for the last ten years (2005-2014). The results show that the issue of marine environment in Korean media reports are signified in the economic context. For the last ten years, news reports are mainly focused on the 'development' issue of marine environment, without distinction of year. The core key words of the networks are "development", "plan", and "project." However, diverse strategies for 'preservation' are not covered in media reports as a major issue. The importance of effective preservation and reasonable development should be considered in a balanced way. Korean media coverages mainly concentrate on the development issue, and it has a strong influence on considering the marine environment area as an object of development. Future direction and implication of the press reports related to marine environment are discussed.

This study is designed to shed light on the current status of school health education in Korea and identify its problems. The findings of this study among other things pointed out that health education should be awarded the status on an independent subject in a bid to activate school health education and cope with its problems. Thus for efforts focused on the needs for establishing health education as an independent course as well as for enhancing the awareness of its importance. At this stage further efforts are needed to develop in-depth discussions and add greater variety to the curriculum. Firstly efforts should be made to recognize the health status of students at all levels, i.d., from kindergarten through university. Particulary at this stage when the entire society is going through changes in the types of health problems and disease pattern, the outcome of analyses on the types of health problems and health-related behavior can be used as basic data for framing the contents of school health education. Secondly more active efforts are required to single out the contents of health education and develop health education curricula assessment based on the findings of surveys on that of health education needs. Thirdly the development of school health education curriculum should be accompanied by that of more effective educational methods and materials. In particular, further efforts should be made to develop educational methods designed to make wider use of audio-visual equipments or apply behavior modification techniques so that school health education will be adapted to changed educational environment and the characteristics of health education. Fourthly and most importantly the training and production competent health education teachers is needed. This should be preceded by the amendment of relevant laws and administrative systems.

Purpose: The purpose of this study was to provide a basis for non-humidified low flow oxygen by nasal cannula and to provide a guide for consistent care in nursing practice. Methods: A methodological study on the development of guidelines with experts' opinions on collected items, framing PICO questions, evaluating and synthesizing texts which were searched with the key words (low flow oxygen, nasal cannula, humidification of oxygen, guideline) from web search engines. Results: Of the 45 researched texts on the web, 9 texts relevant to the theme were synthesized and evaluated. All patients with humidified or non-humidified oxygen therapy reported that they had no discomfort. Conclusion: The results indicate that there are no tangible grounds for patients' perceived differences between the humidified and non-humidified oxygen under 4L/min supplied by nasal cannula. with oxygen. Therefore, non-humidification oxygen therapy is strongly advised when suppling under 4L/min oxygen by nasal cannula (recommended grade A).

This study has examined the influence of VAT frame(VAT included vs. VAT excluded) on the consumer's attitude. Additionally, it has also examined the moderating effect of thinking style(holistic vs. analytic). The experiment stimuli were operated in 4 types[(product: utilitarian/hedonic)x(VAT: included vs. excluded)]. The results of this study can be summarized as follows. 1) The consumers preferred the VAT included frame to the VAT excluded frame. 2) The moderating effect of thinking style appeared. There is no meaningful difference between the VAT included frame and the VAT excluded one to analytic thinkers. But the holistic thinkers preferred the latter to the former. It is expected that this will be helpful to the person in charge of marketing for the company to establish an effective marketing strategy by considering these results.
