In this paper, we present a register renaming method for conditional execution out-of-order instruction issue microprocessors. Register renaming method reduces false data dependencies (write after read(WAR) and write after write(WAW)). To implement a conditional execution out-of-order instruction issue microprocessor using register renaming, we use a register file which includes both in-order state physical registers and look-ahead state physical registers to share all logical registers. And we design an in-order state indicator, a renaming state indicator, a physical register assigning indicator, a condition prediction buffer and a reorder buffer. As we utilize the above hardwares, we can do register renaming and trace the in-order state. In this paper, we present an improved register renaming method using smaller hardware resources than conventional register renaming method. And this method eliminates an associative lookup and provides a short recovery time.

This study aims to analyze the impact of names on stress and self-esteem, comparing before and after renaming. A survey was published and conducted on a renaming club website for the period from 1 April 2013 to 31 May and there were 161 participants. The invitation to survey was limited to members who had changed their names at least six months before the survey and the impact was measured by comparing before and after the first renaming. For the analysis of the data, frequency analysis, t-test, one-way ANOVA and correlation analysis were performed. As a result, the level of stress caused by one's name was lowered after renaming, and one's self-esteem significantly went up compared to before renaming. Therefore, the stress from one's name is believed to affect one's self-esteem, and the study shows that there is a negative correlation as the lower the stress from one's name becomes, the higher one's self-esteem goes up. Therefore, this study is considered to be able to contribute to reducing stress caused by names, as it has proved that the self-esteem increases and the level of stress is lowered after renaming.

The objective of this study is to examine the motivation for renaming and the self-perception scale attained after renaming. The survey was conducted targeting 161 individuals across the country from April 1 to May 31, 2013. The analyzing methods include frequency analysis, correlation analysis, t-test, one-way ANOVA analysis and stepwise regression analysis, etc. All of the empirical analysis was verified at the 5% level of significance. According to the result of analysis, the renamed individuals scored higher on the success scale, the emotional scale and the personality scale after renaming. The study found that the individuals, who adopted a new name as per their own desire, scored significantly higher on the self perception scale. The study will serve as a reference material for persons who desire a new name, based on its result that the greatest motivation for renaming is the "desire to have a good name" and that the biggest changes accompanying the new name are the self confidence and satisfaction which have helped the renamed individuals score higher on the self-perception scale after renaming.

This paper introduces a proper renaming service using variable action and security services against the analysis techniques in Java code. The renaming service that is introduced is separated into API pattern and loop condition. We present our scheme algorithm with known Java obfuscation techniques and tools in order to help readers understanding, and implement prototype to prove practicality in this paper. Test result using prototype shows 73% successful variable renaming rate. Using our scheme, cooperators can intuitionally understand all of code. Also, It helps malware analysts to predict malware action by variable name. But application source code that is developed by Java is exposed to hackers easily using our scheme. So we introduce Java application code protection methods, too.

This paper proposes an efficient method such as Extended Three Region Partitioning Method for nested loops with irregular dependences for maximizing parallelism. Our approach is based on the Convex Hull theory, and also based on minimum dependence distance tiling, the unique set oriented partitioning, and three region partitioning methods. In the proposed method, we eliminate anti dependences from the nested loop by variable renaming. After variable renaming, we present algorithm to select one or more appropriate lines among given four lines such as LMLH, RMLH, LMLT and RMLT. If only one line is selected, the method divides the iteration space into two parallel regions by the selected line. Otherwise, we present another algorithm to find a serial region. The selected lines divide the iteration space into two parallel regions as large as possible and one or less serial region as small as possible. Our proposed method gives much better speedup and extracts more parallelism than other existing three region partitioning methods.

Developed countries have been taking their private security industry to the next advanced level to maintain safety of society, promote cooperative security in conjunction with public security such as the police, cultivate domestic security industry, and spur economic growth. In Korea, Service Security Business Act(currently, Security Business Act) enacted in 1976 laid groundwork for rapid institutional development. Nonetheless, the need to rename current title of Security Business Act has been discussed continuously among scholars and industry. Particularly, a bill(bill no.: 2389) was proposed in 2012 to rename 'Security Business Act' completely to 'Private Security Industry Act'. Under those circumstances, this study was intended to discuss proposals that had been made to rename the Act for underpinning development of security industry, along with its amendment, by gathering opinions from scholars in the field of security. It is undeniable that there is need for renaming the Act. As the renaming of the Act can have positive impact in many aspects for promotion of security industry, the urgency to rename the Act is indisputable. The results suggested that scholars specializing in security hoped the Security Business Act to be renamed primarily to Guard and Security Industry, and if not, to be renamed to Security Industry Act. The renaming of the Act will give rise to the need to amend many parts of provisions contained therein as follow-up action.

This paper introduces region partitioning method of non-perfect nested loops with non-uniform dependences. This kind of loop normally can't be parallelized by existing parallelizing compilers and transformations. Even when parallelized in rare instances, the performance is very poor. Based on the Convex Hull theory which has adequate information to handle non-uniform dependences, this paper proposes an enhanced region partitioning method which divides the iteration space into minimum parallel regions where all the iterations inside each parallel region can be executed in parallel by using variable renaming after copying.

According to the Personal Information Protection Act and Pseudonymization Guidelines, the mapping is processed to the hash value of the combination key generation items including Salt value when different combination applicants wish to combine. Example of combination key generation items may include personal information like name, phone number, date of birth, address, and so on. Also, due to the properties of the hash functions, when different applicants store their items in exactly the same form, the combination can proceed without any problems. However, this method is vulnerable to combination in scenarios such as address changing and renaming, which occur due to different database update times of combination applicants. Therefore, we propose a privacy preserving combination key generation scheme robust to updates of items used to generate combination key even in scenarios such as address changing and renaming, based on the thresholds through probabilistic record linkage, and it can contribute to the development of domestic Big Data and Artificial Intelligence business.

Because there are no unified nomenclature systems for either GES-type or IBC-type extended-spectrum ${\beta}-lactamases$ (ESBLs), we propose a unified and definitive nomenclature system for GES/IBC-type ESBLs. This proposed nomenclature update is greatly helpful in two points: (i) it would not confuse microbiologists studying GES-type ESBLs, fundamentally preventing misleading nomenclature of these antibiotic resistance genes, and (ii) the definitive renaming of GES/IBC-type ESBLs can help some researchers to correctly designate new GES-type ESBLs such as novel enzymes identified trom some nationwide surveys.
