  • General purpose computing applications have not yet been thoroughly explored in procedure level speculation, especially in the light-weighted profiling way. This paper proposes a light-weighted profiling mechanism to analyze speculative parallelism characterization in several classic general purpose computing applications from SPEC CPU2000 benchmark. By comparing the key performance factors in loop and procedure-level speculation, it includes new findings on the behaviors of loop and procedure-level parallelism under these applications. The experimental results are as follows. The best gzip application can only achieve a 2.4X speedup in loop level speculation, while the best mcf application can achieve almost 3.5X speedup in procedure level. It proves that our light-weighted profiling method is also effective. It is found that between the loop-level and procedure-level TLS, the latter is better on several cases, which is against the conventional perception. It is especially shown in the applications where their 'hot' procedure body is concluded as 'hot' loops.

  • The research shows how the technological change of 'Information and Communication Technology' (ICT) is accompanied with the usage change. It aims to provide a better conceptualization with empirical findings about the fact that the technological development of ICT is a convergence process of ICT factors with the usage of ICT moving from a limited coverage toward a general-purpose. The research adapts a descriptive methodology on a historical matter and demonstrates how it can be conducted through analytical description of Input-Output tables (I/O) the over periods. The case is about the UK with sequential I/O during 1970s- 90s.

  • Survivability of the general purpose warhead during the target impact was studied. We first simulated the penetration phenomena and temporarily defined the survivability of the warhead at the impact situation. Next we launched the warhead projectiles by using Counter Mass Gun(CMG) system against the simulated specific steel target. The recovered warheads were carefully investigated and the penetration behaviors were analyzed. As a result the warhead can be hardened efficiently to enhance the survivability with the help of CMG test & analysis.

  • The purpose of this study is to investigate the influences on the understanding and academic achievement in general chemistry according to chemical grades in high school and College Scholatic Ability Test. We investigated the difference between the completed subjects in high school and the elective subjects in the Test, degree of understanding of the general chemistry according to the subjects completed in high school, and the effects on the academic achievement of general chemistry by dint of the chemical grades in high school and the Test, etc. By the results of the student's perception survey, most of the students choose Chemistry I at the Test. It was found that the understanding of general chemistry was greatly affected by the chemical elective subjects of high school. Chemical grades in high school and the Test were found to have a significant influence on academic achievement of general chemistry.

  • Purpose: Here is little information about China's operation department of general hospital in Korean medical architecture papers, which is inconvenient for scholars engaged in medical building research and comparison. Furthermore, Surgery is to provide patients with surgery and rescue sites, is an important technical department of the hospital, and then with the development of medical technology and people's trust in medical science, the role of the operating room will become increasingly important. Therefore, the purpose of this research is to analyze history, changes and definitions of the operating room and China's operation department of general hospital related laws and regulations for future research to provide effective analysis of data, and find shortcomings. Methods: This research was conducted according to the relevant laws, books, and papers of the operation department of Chinese general hospital. Results: At present hospital construction in China is in the period of rapid development and coupled with the growing medical technology, operating room layout and configuration is still in the continuous trial of continuous improvement stage. Overall, it requires more detailed guidelines to improve the quality of the operating room. Implications: Implications: It is expected that the research of this paper will provide an effective reference for the future research of the operation department of China General Hospital, which can promote and improve the work system of the operation department of China General Hospital.

  • Whatever the country, nanotechnology features as a key priority of most national research and innovation policies. This focus on nanotechnology is due to the promises of this general purpose technology, this new technological wave. As 'one size does not fit all', policies supporting its development cannot just adopt the 'best practices' of the preceding wave. We argue that specific on-going dynamics of nanoscience and technology production justifies the existence of dedicated nanotechnology policies. It also questions the portfolio of instruments mobilized and their balance. In this article, we discuss policies developed for the preceding technological waves and, based on the characteristics of nanosciences and technologies, propose five dimensions of policies to be taken into consideration for their governance at the country and cluster levels.

  • Blockchain is an enabling technology for managing data with high trust and transparency among connected computers. Blockchain emerged with the advent of the Bitcoin cryptocurrency, and then, evolved as general-purpose platforms such as Ethereum, EOS, R3 Corda, and IBM Hyperledger Fabric. The application of blockchain covers a broad range of areas such as fintech, decentralized identity, distribution, real estate trading, games, and drone air traffic management. Smart contracts are indispensable for constructing blockchain services. This survey classifies smart contract languages by their features and shows their differences from existing general-purpose programming languages.

  • This study is to compare and analyze the material flow, deformation characteristics, and forming load of flange by means of similitude experimental method of model material using plasticine. In order to find optimal forming conditions, prototype experiments were designed to investigate forming characteristics of general-purpose flange under various working conditions. As a result of prototype experiments, billet thickness and gap-height ratio was found to be the most influential experimental parameter in flange forming. Forming loads from prototype experiments were compared to the results of finite element analysis after conducting estimation of forming loads of real material. Results of prototype experiments based on model material techniques are expected to be used as a basic data of die design f3r the development of products and process.
