Metallic Cr film coatings of $1.2{\mu}m$ thickness were prepared by DC magnetron sputter deposition method on c-plane sapphire substrates. The thin Cr films were ammoniated during horizontal furnace thermal annealing for 10-240 min in $NH_3$ gas flow conditions between 400 and $900^{\circ}C$. After annealing, changes in the crystal phase and chemical constituents of the films were characterized using X-ray diffraction (XRD) and energy dispersive X-ray photoelectron spectroscopy (XPS) surface analysis. Nitridation of the metallic Cr films begins at $500^{\circ}C$ and with further increases in annealing temperature not only chromium nitrides ($Cr_2N$ and CrN) but also chromium oxide ($Cr_2O_3$) was detected. The oxygen in the films originated from contamination during the film formation. With further increase of temperature above $800^{\circ}C$, the nitrogen species were sufficiently supplied to the film's surface and transformed to the single-phase of CrN. However, the CrN phase was only available in a very small process window owing to the oxygen contamination during the sputter deposition. From the XPS analysis, the atomic concentration of oxygen in the as-deposited film was about 40 at% and decreased to the value of 15 at% with increase in annealing temperature up to $900^{\circ}C$, while the nitrogen concentration was increased to 42 at%.

Most companies producing raw materials for other companies usually have a mass production system with a limited number of buyers. Optimization of the manufacturing process for this type of production system will have a big impact on the business competitive power. Pulp industry is a raw material industry consuming a huge amount of electric power. Thus, optimization of its production process is very important to reduce its manufacturing cost. In this paper, DOE(Design Of Experiments) is used to optimize the refining process of the pulp production system for practical field application. And the results are further analyzed not only to improve the pulp quality but also to accumulate knowledge on the process for future innovation.

스페인어 접속법 구문의 이접지시 효과(disjoint reference effect): 자질 평가(feature valuation) 분석

김준한 ( Jun Han Kim ) 한국스페인어문학회 2013 스페인어문학 Vol.0 No.68

The main goal of this paper is to explore the so-called ‘Disjoint Reference Effect (henceforth DRE)`` in Spanish subjunctive construction. On the basis of minimalist approach to Binding Theory, we argue in this paper that DRE is closely related to the feature valuation proposed by Pesetsky & Torrego(2007). Concretely, we propose that DRE, which is observed in subjunctive clauses with volitional matrix verbs, is based on the assumption that volitional verbs subcategorize COMP that has an unvalued uninterpretable T feature (i.e., uT<-val>). Since this assumption makes it possible to extend the binding domain of the null subject pro to vP of matrix clause, we account for the reason why DRE appears only in subjunctive clauses with volitional matrix verbs. On the other hand, to analyze constructions in which DRE does not appear, it is argued that factive-emotional verbs subcategorize COMP that has an valued uninterpretable T feature (i.e., uT<+val>). This suggestion not only makes it possible for a subordinate CP to be a binding domain for the null subject pro, but also explains why the subject pro in subjunctive clause can refer to the matrix subject without violating Binding Condition B.

스페인어 공백화 구문(Gapping Construction)에 대한 다중관할(Multidominance) 분석

김준한 ( Jun Han Kim ) 한국스페인어문학회 2012 스페인어문학 Vol.0 No.65

El principal objetivo del presente trabajo es explicar bajo la teoria minimista la construccion de vaciado en espanol( Spanish Gapping Construction). En el primer capitulo, observaremos desde el punto de vista critico los estudios previos sobre dicha construccion: analisis de borrado( deletion analysis) y analisis de movimiento( movement analysis). En el segundo capitulo, presentaremos las caracteristicas de la construccion de vaciado en espanol, y en el tercero, intentaremos analizar las construcciones de vaciado aplicandoles una nueva idea, es decir, la de Multidominacion( Multidominance), propuesta por Citko(2005), Wilder(1999, 2008), Gracanin-Yuksek(2007, 2009), entre otros. Sobre todo, fijandonos en algunos datos empiricos intentaremos explicar por que no aparece en espanol la restriccion de la oracion subordinada. Para ello, primero analizaremos las construcciones de predicado partido( predicate cleft construction) y luego, propondremos una estructura de multidominacion, en la que se licencia un vaciado en la oracion subordinada.

스페인어 부정명사구(indefinite NPs) 접어 중복(clitic doubling) 연구

김준한 ( Jun Han Kim ) 고려대학교 스페인·라틴아메리카연구소 2015 스페인라틴아메리카연구 Vol.8 No.2

본 논문의 목적은 바스크(Basque) 스페인어, 페루 스페인어와 같은 일부 스페인어에서 나타나는 부정명사구(indefinite NPs) 접어 중복(clitic doubling) 현상의 여러가지 특징을 살펴보고 이를 통사적으로 분석하는데 에 있다. 이를 위해 두 가지의 중요한 가설, 즉 Chomsky(2007, 2008)의 ‘자질 계승(feature inheritance) 가설’과Diesing(1992)의 ‘사상 가설(Mapping Hypothesis)’이 적용되었다. 구체적으로, 우리는 Chomsky(2007, 2008)가 제안한 의무적 자질 계승 가설을 수정하여 일부 스페인어 방언들에서는 v*의 Φ-자질이 V로 계승되지 않을 수 있음을 가정하였고 이 경우v*위치에 남아있는 Φ-자질이 대격 접어로 실현된다고 가정하였다. 이러한 본고의 가설은 Diesing(1992)의 사상 가설과 연계하여 접어 중복 구문에서 나타나는 부정명사구의 의미 해석 분석에 적용되었다. 즉, V로의 자질 계승 없이 v*에서 접어가 실현된 경우 부정명사구는 Spec-v*P 위치로 이동하여 전제적(presuppositional) 또는 부분적(partitive) 해석을 받는다고 가정하였고, 반면 V로의 자질 계승이 일어나는 경우는 접어가 나타나지 않고 부정명사구는 Spec-VP로 이동하여 존재적(existential) 해석을 받는다고 설명하였다. 마지막으로 비특정적(non-specific) 해석을 받는 부정명사구에 대한 접어 중복 구문이 분석 되었다. 이 경우 부정명사구들은 총칭적(generic) 해석 또는 전칭 양화(universal quantification) 해석을 받는 것으로 분석되었는데 이들 명사구들이 Spec-v*P, 즉 제한 영역(restrictive clause)에 위치한다고 가정함으로서 이러한 해석이 주어짐을 설명할 수 있었다. This paper aims to explore the properties of the clitic doubling of indefinite NPs that appears in some Spanish dialects such as Basque and Peruvian Spanish, and to provide an appropriate analysis for them. For this purpose we have proposed a novel analysis of the clitic doubling of indefinite NPs, based on the Feature Inheritance Hypothesis(Chomsky 2007, 2008) and the Mapping Hypothesis(Diesing1992). Concretely, we have proposed a revised Feature Inheritance, which is different from Chomsky``s original one, assuming that the uninterpretable phi-features of v* can optionally (not obligatorily) be inherited by the head V it selects. One of the consequences obtained from this hypothesis is that the clitic doubling is analyzed as a morphological realization of the phi-features in v, which have entered into an Agree relation with a indefinite NP. This assumption is applied to the indefinite NPs`` interpretation, which is related to the Mapping Hypothesis proposed by Diesing(1992). Namely, it is assumed that if the phi-features of v* are not inherited by V, the indefinite NPs move to Spec-v*P, where receive a presuppositional or partitive interpretation, while in case the phi-features of v* are inherited by V, the indefinite NPs move to Spec-VP, where receive a existential interpretation. We also analyze the clitic doubling of the indefinite NPs with non-specific reading. In this case, the indefinite NPs have generic or universal quantification reading, since they occupy Spec-v*P position, which is belong to the restrictive clause.

스페인어 VS(O) 구문과 표찰알고리듬 (Labeling Algorithm)

김준한 ( Jun Han Kim ) 한국스페인어문학회 2014 스페인어문학 Vol.0 No.73

This paper aims to explain Chomsky``s (2013) Labeling Algorithm and to provide appropriate solutions to the problems it contains. Chomsky (2013) argues that the obligatory raising of subject to Spec-TP (i.e., EPP) is no longer driven by feature checking, but the Labeling Algorithm. However, it seems difficult to apply this algorithm to VS(O) constructions which license the postverbal subject in Spec-v*P, since the Labeling Algorithm forces the subject to move out of the base-generated position (i.e. Spec-v*P). In order to resolve this problem, we have proposed a revised Labeling Algorithm, which is different from Chomsky``s original one in that a minimal search operation is applied at the phase level and in ‘top to bottom’ fashion. It is also shown that the revised Labelling Algorithm is compatible not only with VS(O) constructions in Null Subject Languages, but also with SV(O) constructions in non-Null Subject Languages.

스페인어 대격 접어(accusative clitic) 구문: 선택적 자질 계승(optional feature inheritance) 분석

김준한 ( Jun Han Kim ) 한국스페인어문학회 2014 스페인어문학 Vol.0 No.71

his paper aims to explore the properties of Spanish accusative clitic constructions and to provide an appropriate analysis for them. On the basis of the mechanism of Chomsky`s (2007, 2008) and Richards` (2007) feature inheritance, we analyze various accusative clitic constructions in Spanish. Concretely, we propose a mechanism of optional feature inheritance, which is different from Chomsky`s original one in that the uninterpretable phi-features of a phase head can optionally be inherited by the head it selects. One of the consequences obtained from this hypothesis is that the presence of accusative clitics is analyzed as a morphological realization of the phi-features in v, which are left in its original position without feature inheritance. Under our optional feature inheritance analysis, we not only account for the obligatory presence of accusative clitics in clitic left dislocated constructions, but also the obligatory clitic doubling in strong pronoun constructions.
