Cloud computing is widely used in information spreading and processing, which has provided a easy and quick way for users to access data and retrieve service. Generally, in order to prevent the leakage of the information, the data in cloud is transferred in the encrypted form. As one of the traditional security technologies, access control is an important part for cloud security. However, the current access control schemes are not suitable for cloud, thus, it is a vital problem to design an access control scheme which should take account of complex factors to satisfy the various requirements for cipher text protection. We present a novel access control scheme based on proxy re-encryption(PRE) technology (PreBAC) for cipher text. It will suitable for the protection of data confidently and information privacy. At first, We will give the motivations and related works, and then specify system model for our scheme. Secondly, the algorithms are given and security of our scheme is proved. Finally, the comparisons between other schemes are made to show the advantages of PreBAC.

This paper, postulating that Lowell's Imagism is not some "Amygism" that wobbles with "emotional slither," "mushy technique" and "general floppiness" as Pound once mocked, but another kind of poetic discourse that deserves the fullest re-consideration, goes back to the very scene where Pound left for Vorticism, condescendingly allowing Lowell and her supporters to use the name "Imagism" for three years. There, it tries to illuminate how Lowell, making the most of the opportunity given to her, picked up what Pound had left behind, grafted it on the soil of America, and finally fulfilled her literary passion to awaken the common reading public to the taste for poetry reading. For the purpose, it looks into her critical reviews in Tendencies in Modern American Poetry, and stresses her creative critical efforts to re-address Pound's principles of "Imagisme." In particular, given the limit of space, it focuses only on the second principle of her Imagism and examines the modernity of her concepts of "a cadence," "suggestion," and "the real poem beyond." Then it reads "Patterns" in the context of Japanese poetry and Noh drama and analyzes the poetic patterns that Lowell made through a creative adaptation of Japanese aesthetics for Imagist poetics. In doing so, this paper aims to provide reasonable evidences to evaluate the modernity of Lowell's Imagist ars poetica and to consider her a truly serious Imagist poet worthy of a place in the history of American poetic modernism.

Public debate is an essential communication process of our society and now it's carried out generally by television. The purpose of this study is to discuss on the potentialities and limits of TV debate as a public space. First, we examine the way of television's construction of public debate to discover the conventions of the genre. Second, examine its limitation and potentials as an public sphere. We analyse four TV debate programs during one month(June, 2001) using text analysis: format construction, nature of agenda, characteristics of panels and chairman, participation of audience, type of knowledge. The result shows that although numbers of programs are increased, many TV debates not differentiated each other in their format, panel, and contents, and merely reproduce genre conventions. Especially in policy debates, abstract agenda, male-dominated panel, limited participation of audience, and elitism and authoritative are prevailing. The genre's preconceived formulae and fixed convention restrict its own possibility of a participant and democratic public sphere. So, in order for TV debates to function as a open public sphere, to be flexible and re-examinate the proper frame for mass media public sphere.

Objectives: The purpose of this study is to demonstrate empirically through a specialist AHP analysis what factors should be more important in the development of the public health care system. In addition, we will use Analytic Hierarchy Process (AHP) method for experts to achieve research purpose. Methods: The data analysis method of this study is as follows. First, we set up three metrics in order to measure the relative importance between the factors to be improved for the development of the public health care system and each of the sub-factors. A total of nine measurements (items) were set by combining the three measurement criteria for each measurement index. Second, the relative importance and priority analysis use the AHP analysis. Third, the subjects of this study were 15 experts in the field of public health care. The statistical processing was performed using the Expert Choice 2000 statistical program. Results: In order to development of the public health care system, experts ranked the most important as improvement in the systematic aspect of public health care (56%) as the first priority. Next, the relative importance analysis of the measurement items considering the multiple-weights of the sub-factors is as follows. The strengthen institutional improvement (revitalization of secondary public function hospital) was the number one, strengthen cooperation between agencies was the second, and Re-establishing the role of local public health care system was the third place. Conclusions: Considering the relative importance, factors that are considered to be important in the first place may not be improved as the best policy alternative due to limitations in spatial, temporal, financial, and institutional aspects. In this case, we suggest that we should choose the best policy alternative by using prioritization considering relative weights.

This paper examines issues concerning conflicts between arbitral awards and public interests, particularly with respect to economic sanctions. Sanctions have been widely used by political entities, such as States and organizations, as means to promote public interests and to resolve cross-border disputes. In particular, economic sanctions have been increasingly more visible in recent years due to the accelerating fragmentation of the international communities, and their magnitude and range of the impacts have grown accordingly. For example, the U.S. and the EU have imposed economic sanctions on Russia and related persons in response to Russia's invasion of Ukraine. The U.S. recently re-introduced a comprehensive economic sanction on Iran. One of the notable impacts of the sanctions, particularly economic sanctions, is that on international arbitration. Sanctions are essentially built on the notion of the protection of public interests, and public interests are some of the few grounds upon which recognition and enforceability or arbitral awards may be rejected. However, jurisprudence on such conflict between sanctions and arbitral awards have not been sufficiently addressed in Korea because court case and administrative decision records on this conflict have not been sufficiently accumulated. In this regard, this paper begins with offering a survey of the concept of public interests, economic and trade sanctions, arbitral awards and their enforceability, and the relationships between them. It then examines the mechanism upon which public interests, trade and economic sanctions may lead certain arbitral awards unenforceable. Next, the paper suggests judiciaries' balanced approach toward the public interests protected by trade and economic sanctions and the predictability and fairness in the enforcement of arbitral awards. Finally, this paper concludes with the methods of the implementation of such balanced approach.

Recently, a concept of bid-rigging is issued in electronic auction. To prevent this attack, Abe-Suzuki proposed firstly receipt-free scheme based on bidding-booth. Chen-Lee-Kim pointed out that Abe-Suzuki's scheme only provides receipt-freeness for losing bidders. Also, they introduced a new receipt-free sealed bid auction scheme using the homomorphic encryption technique. The main participants of their scheme are Auctioneer, Auction Issuer, Bidder and Seller. Bid-rigging can happen by a seller in their scheme. We propose receipt-free sealed-bid auction scheme using a universal re-encryption mixnet. For our receipt-free sealed-bid auction, we use Pseudo ID of a bidder and universal re-encryption technique of Golle et al. Also, our scheme satisfies privacy, correctness, public verifiability, non-reputation, and receipt-freeness.

The Republic of Korea, ranked as the 5th military power according to the size of its ground troops, discharges more than 200,000 manpower to the society annually; more than 13,000 of them are officers. The re-employment rate of discharged military personnels, who experience early retirement of 5 to 15 years compared to general public officers, is very low, only amounting to 53.2%. On the other hand, major developed countries exhibit great national scale of effort to take responsibility in helping the settlement of the soldiers who have dedicated their career for their countries. The re-employment rate amounts to 94%. Fully acknowledging such disparity, this paper examines various policies on discharged members support of developed countries, and aims to suggest developmental model on employment support designed for discharged members in the Republic of Korea.

This study intends to make a counterproposal for re-building existing high-rise/high-dense buildings and for planlessly re-constructing multi-dwellings. Also, it proposes the plan instruction fur reconstruction by small collective housings through annexing parcels in the residence Inner area. This study can be summarized as below: (1) Remained site generated by site boundaries can be utilized by annexing two or more parcels. (2) Vacant lots between buildings can be utilized as building space or common space by small-sized annexation. (3) Bad effect of residential environment caused by simultaneous development of total blocks can be minimized. (4) Formation of site size and plane, which are advantageous to reconstruction, is available. (5) Accessibility to neighboring roads can increase. (6) Residents' participation in development can increase in economical and planning aspect. In order to utilize these planning instruction, residents' participation and improved public ownership system for parcel annexation are required.

Objectives: Malaria remains a public health concern worldwide, including Indonesia. Purworejo is a district in which endemic of malaria, they have re-setup to entering malaria elimination in 2021. Accordingly, actions must be taken to accelerate and guaranty that the goal will reach based on an understanding of the risk factors for malaria. Thus, we analysed malaria risk factors based on human and housing conditions in Kaligesing, Purworejo, Indonesia. Methods: A case-control study was carried out in Kaligesing subdistrict, Purworejo, Indonesia in July to August 2017. A structured questionnaire and checklist were used to collect data from 96 participants, who consisted of 48 controls and 48 cases. Univariate, bivariate, and multivariate analyses were performed. Results: Bivariate analysis found that education level, the presence of a cattle cage within 100 m of the house, not sleeping under a bednet the previous night, and not closing the doors and windows from 6 p.m. to 5 a.m. were significantly ($p{\leq}0.25$) associated with malaria. Of these factors, only not sleeping under a bednet the previous night and not closing the doors and windows from 6 p.m. to 5 a.m. were significantly associated with malaria. Conclusions: The findings of this study demonstrate that potential risk factor for Malaria should be paid of attention all the time, particularly for an area which is targeting Malaria elimination.
