Hubert Mecke,Reinhard Doebbelin,Wolfgang Fischer 전력전자학회 1998 ICPE(ISPE)논문집 Vol.- No.-

In recent years inverter power sources are more and more used for resistance welding processes. In this paper some results of investigation into the static and dynamic behavior of high-current rectifier diodes used in these inverter power sources will be discussed. By means of digital simulation, losses and efficiency have been determined depending on the power semiconductor parameters.<br/>

Phonological Awareness Integrated Instruction

Hubert H. Pak 한국영어어문교육학회 2011 영어어문교육 Vol.17 No.3

Research studies have shown that phonological awareness focused analogies and anagrams can be used as an effective game-based teaching instruction. However, previous studies used analogies and anagrams as separate instructional tools, especially in EFL-related situations. There has been no vocabulary learning in analogies/anagrams instruction provided, nor has there been usage of an integrated workbook for ‘vocabulary learning and analogies/anagrams’. This study examined the effect on learners’ vocabulary acquisition scores when a truly phonological awareness integrated ‘analogies/anagrams and vocabulary learning’ workbook was used as an instructional practice workbook. The results show that the phonological awareness integrated instruction significantly increased learners’ vocabulary acquisition scores among 40 college students with minimal or basic level of English proficiency.

The Effect of Films with and without Subtitles on Vocabulary Acquisition Scores of Foreign Language Learners: Using a Korean Sit-com, Unhindered High-Kick

Hubert H Pak 영상영어교육학회 2012 영상영어교육 (STEM journal) Vol.13 No.3

Research has shown that cognition and reasoning styles differ across cultures, and the purpose of this study was to discover the differences in language learning style between two different cultures. Today, it is widely believed that a foreign language can be learnt through watching subtitled programs in and out of the class. The present study represents a preliminary effort to empirically examine the efficacy of subtitled program on vocabulary acquisition scores of intermediate "Korean as a Foreign Language (KFL)" students. To examine the effects of subtitles on vocabulary acquisition, two groups (21 Chinese and 21 American students) of language learners studying conversational Korean at the Institute of Korean Language and Culture Education at a university participated in the study. Each of the groups watched three episodes of a Korean sitcom each with a different type of subtitling: a) interlingual, b) intralingual and c) without any subtitles. After watching each episode, 25 short-answer open-ended vocabulary questions were given to both groups. The results revealed that Chinese students acquired less vocabulary when watched the episodes with subtitles whereas both interlingual and intralingual subtitles were more conductive to vocabulary acquisition for American students.

Prosodic Descriptions in EFL Learning and Teaching: A Theoretical Perspective

Hubert H. Pak 현대영미어문학회 2007 현대영미어문학 Vol.25 No.4

This paper looks at a component of language that is involved in foreign language learning - pronunciation - and presents the main trends in these areas that have potential for language teaching. While the EFL acquisition of grammar has been widely studied, the prosodic descriptions have been covered much more patchily and are hardly referred to in most standard introductions to EFL pronunciation learning research. Despite the obvious relevance to EFL teaching, much has yet been done to apply them to actual pronunciation teaching. While there are indeed any number of recent researches on teaching vocabulary and discourse, these are usually based on language description and teaching methodology rather than on concepts from language acquisition. It is evident from the studies on intonational phonology, that an utterance is made up of prosodic words (as well as lexical words) that have a linguistic significance. In teaching the prosody of a language, it should be possible to apply the same paradigm as used in teaching grammatical structures. Thus, the aim of teaching prosody is not to explicitly teach a formalized phonology of prosody, but there is far more to components of language teaching than this. One of the implications of EFL acquisition research is that thinking about language learning and language teaching means thinking about what language is.

PLUTONIUM MANAGENENT OPTIONS: LIABILITY OR RESOURCE

HUBERT BAIRIOT 한국원자력학회 2008 Nuclear Engineering and Technology Vol.40 No.1

Since plutonium accounts for 40-50% of the power produced by uranium fuels, spent fuel contains only residual plutonium. Management of this plutonium is one of the aspects influencing the choice of a fuel cycle back-end option: reprocessing, direct disposal or wait-and-see. Different grades and qualities of plutonium exist depending from their specific generation conditions; all are valuable fissile material. Safeguard authorities watch the inventories of civil plutonium, but access to those data is restricted. Independent evaluations have led to an estimated current inventory of 220 t plutonium in total (spent fuel, separated civil plutonium and military plutonium). If used as MOX fuel, it would be sufficient to feed all the PWRs and BWRs worldwide during 7 years or to deploy a FBR park corresponding to 150% of today’s installed nuclear capacity worldwide, which could then be exploited for centuries with the current stockpile of depleted and spent uranium. The energy potential of plutonium deteriorates with storage time of spent fuel and of separated plutonium, due to the decay of 241Pu, the best fissile isotope, into americium, a neutron absorber. The loss of fissile value of plutonium is more pronounced for usage in LWRs than in FBR. However, keeping the current plutonium inventory for an expected future deployment of FBRs is counterproductive. Recycling plutonium reduce the required volume for final disposal in an underground repository and the cost of final disposal. However, the benefits of utilizing an energy resource and of reducing final disposal liabilities are not the only aspects that determine the choice of a back-end policy

Visibility of Sutures of the Orbit and Periorbital Region Using Multidetector Computed Tomography

Hubert Gufler,Markus Preiß,Sabrina Koesling 대한영상의학회 2014 Korean Journal of Radiology Vol.15 No.6

Objective: Knowledge of cranial suture morphology is crucial in emergency medicine, forensic medicine, and maxillofacial reconstructive surgery. This study assessed the visibility of sutures of the orbit and periorbital region on multidetector computed tomography. Materials and Methods: Multidetector computed tomography scans of 200 patients (127 males, 73 females; mean age 51.3 years; range, 6–92 years) were evaluated retrospectively. The slice thicknesses varied from 0.5 to 1 mm, and the tube current from 25 to 370 mAs, depending on the CT indication. The visibility of sutures was estimated according to a 4-point scale from “not visible” to “well visible”. The chi-squared test was used to test the association of the visibility of sutures with the slice thickness, tube current, and age of patients. Statistical significance was assumed at p < 0.05. Results: Overall, best visibility was found for the sutura frontozygomatica (98%), sutura frontonasalis (88.5%), and sutura sphenozygomatica (71.5%), followed by the sutura zygomaticomaxillaris (65.8%), sutura temporozygomatica (41.8%), sutura frontomaxillaris (44.5%), and sutura sphenofrontalis (31%). Poor visibility was found for the sutura frontolacrimalis (16.8%) and sutura frontoethmoidalis (1.3%). The sutura ethmoidomaxillaris, sutura lacrimomaxillaris, and sutura ethmoidolacrimalis were not visible. Conclusion: Although the sutures of the superior, lateral, and inferior orbit are well visible, those of the medial orbit are poorly visible on CT scans.
