As XML becomes popular as the way of presenting information on the web, how to secure XML data becomes an important issue. So far study on XML security has focused on security of data communications by using digital sign or encryption technology. But, it now requires not just to communicate secure XML data on communication but also to manage query process to access XML data since XML data becomes more complicated and bigger. We can manage XML data queries by access control technique. Right now current XML data access control only deals with read operation. This approach has no option to process update XML queries. In this paper, we present XML access control model and technique that can support both read and update operations. In this paper, we will propose the operation for XML document update. Also, We will define action type as a new concept to manage authorization information and process update queries. It results in both minimizing access control steps and reducing memory cost. In addition, we can filter queries that have no access rights at the XML data, which it can reduce unnecessary tasks for processing unauthorized query. As a result of the performance evaluation, we show our access control model is proved to be better than other access control model in update query. But it has a little overhead to decide action type in select query.

Persons who are waiting for decision of the court concerning whether they are guilty or not after they are involved in the criminal case and detained in the special institution isolated from society, will desire to de found innocent and acquited or to be slightly punished. Inmates are the suspected persons and the accused persons who are detained in the correctional institution. They have the right to de assisted by lawyes in order to receive the favorable verdict in the court. However, the right of the poor and the ignorant, in reality, cannot be perfectly protected due to the imperfection and defect of the defense counsel system itself and its application. Therefore, as a means to guarantee the so-called access to the court, the fundamental constitutional right, the law libraries are established and the legal information services are provided to the inmates within the correctional institution in the advanced country such as the United States. In addition, the judicial precedent and the various kinds of professional organizations provide the managerial guide-lines for such libraries to enoughly collect materials and to provide the effective information services to the inmates. In order to furnish the management of the correctional institution of Korea with useful information, the legal information services, materials collected, and information service personnel of the law libraries within the correctional institution are minutely examined in this paper.

Today's environment of enterprise is changing. They have to face customer' demands with the right product, the right service and supply them at the right time. And also cut down logistics and inventory cost and bring up the profit as much as they can. This means the change of putting enterprise first in importance to putting customer first importance. therefore to correspond to customer's demand, shorting lead time is becoming a essential condition. The answer to this changes of environment is supply chain management. In the Supply chain, The ATP function doesn't only give customers to conformation of delivery. It can be used by the core function with ATP rule that can reconcile supplies and demands on the supply chain. Therefore We can be acquire the conformation about on the due date of supplier by using the ATP function of management about real and concurrent access on the supply chain, also decide the affect about product availability due to forecasting or customer's orders through the ATP. In this paper, It consolidates the necessity on a CTP and analyzes data which is concerned of ATP. Under the these environments, defines the ATP rule that can improve the customer value and data flow related the LTV(Life Time Value) and builds on a algorithm.

Mobile Crowd Computing is one of the most efficient and effective way to collect the Electronic health records and they are very intelligent in processing them. Mobile Crowd Computing can handle, analyze and process the huge volumes of Electronic Health Records (EHR) from the high-performance Cloud Environment. Electronic Health Records are very sensitive, so they need to be secured, authenticated and processed efficiently. However, security, privacy and authentication of Electronic health records(EHR) and Patient health records(PHR) in the Mobile Crowd Computing Environment have become a critical issue that restricts many healthcare services from using Crowd Computing services .Our proposed Efficient Multi-layer Encryption Framework(MLEF) applies a set of multiple security Algorithms to provide access control over integrity, confidentiality, privacy and authentication with cost efficient to the Electronic health records(HER)and Patient health records(PHR). Our system provides the efficient way to create an environment that is capable of capturing, storing, searching, sharing, analyzing and authenticating electronic healthcare records efficiently to provide right intervention to the right patient at the right time in the Mobile Crowd Computing Environment.

In this paper, we analyze the security of OFB encryption mode which is one of the basic modes of operation for the block cipher and the security of 3GPP f8 encryption mode used to provide the data confidentiality over a radio access link of W-CDMA IMT-2000. We provide the lower bound and the upper bound on security of both modes in random function model and random permutation model, respectively, by means of the left-or-right security notion, and prove the security of both modes using a pseudorandom function and a pseudorandom permutation, respectively.

This paper researched that consumers who lived in the local small cites have a restricted and insufficient problem to screening the animation film comparing with those of capital area and the other broader local cities. And these kinds of problems caused more serious problems like a infringement of copy right as a result. This paper calculated and evaluated that the rate possibilities of criminal infringement copy right in supposing that giving the opportunity screening the all of the first-run movies the most highest criminal group in Chuncheon where the worst benefit area in aspect of screening circumstances. As a result of this research, this paper could suggest that the possibility to reduce the criminal infringement of copy right and the necessity of structural reconstruction throughout rebuilding of animation distribution and consciousness of consumers. Thus this paper try find out the importance of reducing the rate of criminal infringement copy right by recontruction of structrual access of local animation business.

Cultural welfare is the cultural activity provided and supported by state, a local autonomous entity, and private organizations to improve the quality of people's life. And as a basic concept as well as a premise of discussion on cultural welfare, cultural right is a social right, a right which can make cultural express, gain access to cultural activities. A statue concerning cultural activities contributed to the promotion of our people's cultural welfare interwoven with cultural right. But laws were made for the purpose of enforcing national policy and supporting regime rather than promoting fundamental human rights, and they became effective and were understood as a mere part of national government, not as perspective of their execution, security of right or realization of them. On the other hand, based on laws concerning social welfare, cultural life means human life consisting of minimum welfare system, and minimum level of life which guarantees least cultural life is becoming an objective standard. This means the standard level of cultural right, and for the handicapped cultural rights are concretely guaranteed as a right in that they will not be discriminated for their approaching to cultural activities. However, laws concerning cultural activities have limitation in that there are ambiguous concept and limitation of cultural life, and there are no concrete and active laws about cultural rights to guarantee cultural life. In a constitution and laws concerning social welfare, cultural welfare must have concrete contents about the range and the level of cultural rights. In order cultural rights to be turned into complete ones which can assert its rights, as seen in the Supreme Court, a court has to try to understand the violation of cultural rights as the violation of legal rights.

Purpose To assess the safety and feasibility of intentionally positioning the catheter tip in the right atrium (RA) without an abutment during implantation of a totally implantable venous access port (TIVAP). Materials and Methods We enrolled 330 patients who had undergone TIVAP implantation between January and December 2016 and postoperative chest CT. The TIVAP was placed using the single-incision technique to access the axillary vein directly from the incision line. To position the catheter tip in the RA without abutment, blood return was checked before cutting. Catheter length and complications were evaluated by retrospectively reviewing medical images and records. Results All patients achieved successful catheter tip positioning without abutment or dysfunction. The median tip position was 15.3 mm distal to the cavoatrial junction (CAJ) on fluoroscopy and 6 mm distal to the CAJ on CT. Catheter tips migrated a median of 10.4 mm cephalically on CT compared to fluoroscopy. Thromboses were detected in the RA and superior vena cava in one patient each. Conclusion Intentional catheter tip positioning in the RA without abutment is a safe and feasible technique with a low incidence of thrombosis and no observed dysfunction.
