This study proposes a new soft-switching three-level flying capacitor converter with low filter inductance. The proposed converter can achieve zero voltage switching (ZVS) turn-on of all switches by using auxiliary components La and Ca. It can also reduce filter inductance because the applied voltage of the filter inductor is decreased by using the flying capacitor. Furthermore, filter inductance can be reduced because the operating frequency of the filter inductor is doubled by the phase shifting between switches S3 and S4. The operation principle, design of passive components for ZVS turn-on, interleaving effects, and comparison of different topologies are presented. The experimental waveforms of a 1 kW two-phase interleaved converter prototype are provided to verify the validity of the proposed converter.

This article presents key research needs in three-dimensional integrated circuit (3D IC) architectural floorplanning. Architectural floorplaning is done at a very early stage of 3D IC design process, where the goal is to quickly evaluate architectural designs described in register-transfer level (RTL) in terms of power, performance, and reliability. This evaluation is then fed back to architects for further improvement and/or modifications needed to meet the target constraints. We discuss the details of the following research needs in this article: block-level modeling, through-silicon-via (TSV) insertion and management, and chip/package co-evaluation. The goal of block-level modeling is to obtain physical, power, performance, and reliability information of architectural blocks. We then assemble the blocks into multiple tiers while connecting them using TSVs that are placed in between hard IPs and inside soft IPs. Once a full-stack 3D floorplanning is obtained, we evaluate it so that the feedback is provided back to architects.

This study empirically examined the impact of national culture on the amount of information provided by management accounting information systems (MAIS). Two very different cultures, the Korean and Australian cultures, were considered in our study The results showed that the much more flexibility performance information is provided in Korean firms, while the amount of quality performance information and traditional cost control information (TCCI) produced in Australian firms is much more than in Korean firms. However, it was found that in the amount of financial performance information and advanced cost control information (ACCI), there exist no significant differences between Korean firms and Australian firms. We also investigated the effect of the three-way interactions among national culture, level of advanced manufacturing technology (AMT), and information on production performance. The results of this study revealed a significant impact of three-way interactions on the improvement of production performance. In conclusion, we suggest that under high levels of AMT, Korean firms need a large amount of information-based MAIS, while Australian firms require the ACCI and nonfinancial performance information-oriented MAIS.

The purpose of this study is to investigate the diverse constructive characteristics which significantly affects performance besides materials information provided to consumers on functional clothes. Outdoor jackets can classified them according to their performance level. In order to provide consumers with necessary information to choose functional outdoor jackets, 12 brands selling domestic outdoor jackets were investigated and the conclusion of this study was as follows; It was found that fit degree, backpack weight, arm-raise, and number of pockets vary differently depending on performance level of outdoor jacket. Considerable constructive difference was found between high performance jacket mainly worn by professional climbers in extreme environment and jacket that can be worn in daily life. It is found that different characteristic is related not only to each diverse & complex constructive aspect, but also to ability to stretch, resistance to water, venting system of materials depending on performance level of outdoor jacket.

This study examined the effects of previewing and providing background knowledge on low level EFL readers' comprehension of expository texts and their responses to these treatments. 130 college freshmen were randomly placed into one of three treatment groups and read two expository texts reflecting unfamiliar cultural information. Prior to reading, one group was given previewing instruction, which included vocabulary preteaching and summaries, and a second group was provided with culture-specific background knowledge through watching videos and slides. The third group read each text without any prereading instruction. Immediately after reading a passage, subjects answered a 10-item multiple-choice test. Results showed significant positive effects of the previewing treatment and weak positive effects of the providing background knowledge treatment. Students' responses on the questionnaires revealed that the majority felt that the experimental treatments contributed to comprehension enhancement, made reading more enjoyable, and expedited their reading process. Students in the control group, however, indicated that they needed explicit prereading instruction in order to understand the texts. Pedagogical implications of the findings for EFL reading instruction are provided.

When starting a new project, generally similar existing projet are searched. As Building Modeling Information(BIM) has short history and experience, the dependence on similar project is high. Small and medium sized design companies are depending on website search tool for information of BIM project besides companies maintaining the Database(DB) from lots of project experience. However, the information level and contents provided by websites differ drastically from each other which makes it difficult to utilize the information and apply cases. Furthermore, the different classification system of the sites makes the situation even worse. Therefore, we collected and analyzed over 100 BIM cases from 18 global websites, to develop a system for BIM case application. Result showed that over 90% of our subject pool provided basic information including the construction type, characteristics of the client (public/ private), location of the project, and detailed information such as primary usage. Moreover, the reasons for applying BIM where to solve problems of geometric design, building system like MEP and construction. Furthermore, there was a contrast between cases conducted only within Korea and cases conducted with other countries. While there was almost always helpful information regarding the administrative steps for Korean BIM cases, there was close to no information for projects carried out outside of Korea. These results could contribute to verifying the trend of information provision of the websites for BIM projects data, and this is believed to be helpful for developing an application system for BIM cases which have an organized information provision system and level as well as for bench marking.
