The purpose of this study is to analyse diverse functions and uses of Spanish article lo. Spanish is the only Romance language which has preserved an neutral and unchangeable article, which is called 'article lo'. Lo can nominalize the adjectives, which, in this way, acquire a meaning equal or similar to that of the neuters of Latin. The nominalization with lo gives abstract character to the adjectives in competition with abstract nouns, etymologically and semantically correlatives. This study is composed of four chapters, an introduction and a conclusion. The first chapter focuses on the difference between 'article lo'(lo esperado) and 'pronoun lo'(lo esperaba). And we examine a variety of uses of Spanish articles by dividing the second chapter into two sections: the comparison of the definite article with the indefinite one (el libro/un libro), and diverse characteristics of the article lo. The third part, the analysis of different functions and uses of the article lo, is divided, in its turn, into three sections: 'lo + adjective'(lo noble=la nobleza; lo bueno=las cosas buenas; en lo alto=en la parte alta), 'lo + relative clause'(toma lo que quieras), and 'lo + adjective/adverb + que'(todos saben lo simpatica que es tu hermana). The fourth chapter addresses impersonal expressions with a sense of topicalization(lo imporante es (que)=es importante (que) ), and idiomatic phrases, which are structured with lo(a lo lejos); and shows how the article lo is interpreted into other languages like English, French and Italian. This investigation on lo is believed to contribute to our understanding of its diverse functions and also to the solution of various communication problems.
A New Database Operator Definition and Searching Algorithm for Snesor Networks
Seungjae Lee,Changhwa Kim,Sangkyung Kim 대한전자공학회 2007 ITC-CSCC :International Technical Conference on Ci Vol.2007 No.7
Most sensor networks are currently used to gather sensing data from a broad environment in which it is very difficult to deploy the existing networks (e.g., internet). Recently, researches on relational database approaches to sensor networks are being tried. There occur, however, some problems in applying directly the traditional relational database concepts into a sensor network. For instances, consider the following examples: How can we write a query to get locations at which temperature is 22℃, given a sensor network area where there are some spots with exact 22℃ but there is no sensor node to announce exact 22℃. For a solution about the above described problems we propose in this paper a new database operator for the sensor network and a searching algorithm for this operation. This new operator allows to create tuples with existing tuples. As a result, this new database operator with the new searching algorithm can provide more effective data management and standard interfaces to application programs in sensor networks. Furthermore, it is also helpful to spare node's energy by reducing the number of communications in processing a query.
Effect of Maleic Anhydride-grafted Polypropylene on Recycled Carbon Fiber Reinforced Polypropylene

플라스틱 기반 폐기물의 문제가 증가되면서 탄소섬유 복합재료(CFRPs)는 폐순환 재료 수명 주기를 달성할 필요가 있다. 본 연구는 폴리프로필렌(PP)을 사용한 재생 탄소섬유 복합재료(rCFRPs)의 잠재성을 연구하는 것을 목표로 한다. PP는 관능기가 없기 때문에 기계적 물성 향상을 위해 말레산 무수물이 그래프트된 폴리프로필렌(MAPP)을 커플링제로 사용하였다. rCFRP는 재생 탄소섬유(rCF) 습식부직포와 매트릭스 필름을 포개어 압축성형으로 제조하였다. 충분한 산소 관능기가 rCF 표면에 존재함을 확인했으며 그 관능기들은 말레산 무수물(MA)과 rCF 표면의 공유결합에 의한 기계적 물성 향상에 기여하였다. rCFRP의 인장특성은 2wt%의 MAPP 첨가만으로도 극적인 향상을 보였지만 5 wt%까지 MAPP의 함량에 대한 효과는 미미하였다. As the problem of plastic based material waste is increasing, carbon fiber reinforced plastics (CFRPs) need to achieve closed life cycle. This study aims to investigate the potential for recycled carbon fiber reinforced plastics (rCFRPs) with polypropylene (PP). To improve mechanical properties of rCFRP, maleic anhydride grafted polypropylene (MAPP) was used as a coupling agent due to absence of functional group in PP. The rCFRPs were prepared by compression molding after stacking of recycled carbon fiber (rCF) wet-laid nonwovens and matrix films. The sufficient oxygen functional groups observed on rCF surface and they contributed to improve mechanical properties by covalent bond between maleic anhydride (MA) group and rCF surface. The tensile properties of the rCFRP with 2 wt% MAPP were dramatically increased compared to that without MAPP. However, the effect of MAPP content until 5 wt% on the tensile properties was slight.
Global Market Analysis for Welding Power Source and Welding Robot (I)
Seungjae Lee,Jason Cheon,Cheolhee Kim 대한용접·접합학회 2020 대한용접·접합학회지 Vol.38 No.3
Welding power source and welding robot are the most important components of welding automation systems. In this paper, we summarized the sales and market revenues of welding power source and welding robot using the market analysis reports from 2007 to 2017. The analysis was conducted for arc welding and resistance welding, respectively. The power source market of 2017 returned to that of 2007, and the welding robot market of 2017 approximately doubled that of 2007. These market trends are found to be closely related to the major application industries such as the heavy industry and the automotive industry.
Deficits in Facial Emotion Recognition in Schizophrenia: A Replication Study with Korean Subjects
SeungJae Lee,HaeKook Lee,YongSil Kweon,ChungTai Lee,KyoungUk Lee 대한신경정신의학회 2010 PSYCHIATRY INVESTIGATION Vol.7 No.4
Objective-We investigated the deficit in the recognition of facial emotions in a sample of medicated, stable Korean patients with schizophrenia using Korean facial emotion pictures and examined whether the possible impairments would corroborate previous findings. Methods-Fifty-five patients with schizophrenia and 62 healthy control subjects completed the Facial Affect Identification Test with a new set of 44 colored photographs of Korean faces including the six universal emotions as well as neutral faces. Results-Korean patients with schizophrenia showed impairments in the recognition of sad, fearful, and angry faces [F(1,114)=6.26, p=0.014; F(1,114)=6.18, p=0.014; F(1,114)=9.28, p=0.003, respectively], but their accuracy was no different from that of controls in the recognition of happy emotions. Higher total and three subscale scores of the Positive and Negative Syndrome Scale (PANSS) correlated with worse performance on both angry and neutral faces. Correct responses on happy stimuli were negatively correlated with negative symptom scores of the PANSS. Patients with schizophrenia also exhibited different patterns of misidentification relative to normal controls. Conclusion-These findings were consistent with previous studies carried out with different ethnic groups, suggesting cross-cultural similarities in facial recognition impairment in schizophrenia.
