Clutter signals are undesired for radar detection. Clutter signals can be categorized as volume, land, and sea clutter. These unwanted signals disturb radar by detecting the target. To increase detection accuracy, the radar must be able to differentiate clutter signals from the target and remove cluttering signals. Therefore, it is important to understand the characteristics of clutter signals. In this paper, we review the characteristics of land clutter signals and the methods used to generate them.

김태인,송태식,김기성,한준현 대한치과이식임플란트학회 2002 The Korean Academy of Implant Dentistry Vol.21 No.1

Screw loosening in dental im plant treatment is one o f the m ajor problem that has been frequently reported by m ultiple authors. There are several factors involved in keeping im plant screws tight. The purpose o f this study was to determine whether various im plant fixture and abutment connection system w ould affect screw looseness. Im plant fixture and abutment o f the four different connection system were connected and tightened w ith 30N Cm and then the loosening torque was measured. T ightening screw removal values were measured 10 times repeatedly under same condition. The results were as follow s. 1. The highest loosening torque value appeared after tightening 3-5 times repeatedly. 2. Morse taper connection system showed statistically significant high loosening torque value. There were no significant difference in loosening torque values w ith other connection system, spline, internal hex, external hex.

Nonsubmerged 임프란트 식립후 조직형태학적 반응과 시간경과에 따른 Periotest? 측정값에 대한 연구

김태인,이재일,양복렬,송태식 한국생체재료학회 2003 생체재료학회지 Vol.7 No.4

The purposes of this study was to evaluate Periotest values regarding to functional changes and compare Periotest values(PTV) to histologic findings with a nonsubmerged "Protect-447" dental implant. In the first part of the study, PTV measurements of 10 nonsubmerged implant were done immediately after implant placement and repeated every 2 weeks up to 3 months in beagle dogs. Mean PTV for nonsubmerged implants increased on 2 weeks after surgery and then decreased gradually from 4 weeks after implant placement. After 3 month of experimentation, in the 2nd part, PTV of the each implant were measured and the implants with surrounding bone were removed for the histomorphometric analysis. The results were as follows. 1. Histomorphometric analysis after 3 months showed that osseointegration was obtained successfully without fibrous connective tissue at the interface and bone-implant contact ratio was 64.43%±10.53 in beagle dogs. 2. PTV measurements during the 3 months experiments showed that Protect-447 dental implant could be osseointegrated with an excellent primary stability.

‘쉽다’가 구성하는 구문에 관한 몇 가지 문제

김태인 형태론 2020 형태론 Vol.22 No.1

Through this article, I have considered some of issues of the construction of ‘swipta’. First, ‘swipta’ has two functions of the objective adjective and subjective adjective depending on the context. In the case that ‘swipta’ is a subjective adjective, it is a two-place predicate, and in the case that ‘swipta’ is an objective adjective, ‘swipta’ is a one-place predicate. Based on the frequency from corpus, ‘swipta’ almost has uses as objective adjectives. In this case, the argument of ‘swipta’ is the ‘-ki’ complement clause. At the same time, there is a phenomenon that the accusative argument in the ‘-ki’ complement clause is raised to the main clause as a subjective term. In this article, I figured out that these two sentences have different meanings and different syntax structures. Occasionally, when ‘swipta’ takes the physical individual nouns as the subject, these nouns are interpreted as ‘a typical event that can be done with that noun’. ‘swipta’ takes the event type as an argument, therefore, the noun is forced to be interpreted as the event type. In this paper, I explained it as the ‘type coercion theory’. Constructions of ‘swipta’ are divided into two meanings. One is the ‘manner interpretation’ relating to the development process as the sub-event structure, and the other is the ‘frequency interpretation’ relating to the single entire event. Concerning the link between these two interpretations, we can find it from the phenomenon that a lexical element expressing [ability] is grammaticalized to the one expressing possibility that some event can occur. 본고에서는 ‘쉽다’가 구성하는 구문이 보이는 몇 가지 문제를 고찰해 보았다. 우선 ‘쉽다’는 문맥에 따라 객관형용사와 주관형용사의 쓰임을 모두 갖는다. 주관형용사의 경우 2항 술어이고 객관형용사의 경우 1항 술어이다. 말뭉치의 빈도를 통해 보면 객관형용사의 쓰임이 많고 이 1항도 대체로 ‘-기’ 보절로 나타난다. 이때 ‘-기’ 보절 내에 있는 대격 논항이 주절의 주어로 인상되는 현상이 있다. 본고에서는 인상 전 구문과 인상 후 구문이 다른 의미와 다른 통사 구조를 가진 것으로 파악하였다. 드물게 ‘쉽다’가 개체 명사를 주어로 취할 경우, 해당 개체 명사는 ‘해당 명사를 가지고 할 수 있는 전형적인 사건’으로 해석이 된다. ‘쉽다’는 논항으로 사건이 올 것을 요구하고, 이에 개체 유형이 사건 유형으로 해석되기를 강요받는 것이다. 본고에서는 이를 유형 강제 이론으로 설명하였다. ‘쉽다’가 구성하는 구문은 크게 두 가지 의미로 대별된다. 하나는 사건의 하위 구조인 전개 과정과 결부되는 ‘수월 해석’이고, 다른 하나는 단일한 전체 사건과 결부되는 ‘빈번 해석’이 그것이다. 이 둘의 연결 고리는 ‘-을 수 있다’나 ‘잘’이 그러한 것처럼 능력을 나타내는 어휘가 어떤 일이 일어날 가능성을 나타내는 표현으로 문법화되는 현상에서 찾을 수 있다.

서남방언 담화표지 ‘이’ 고찰

김태인 한국방언학회 2015 방언학 Vol.0 No.21

This paper aims at characterizing the synthetic distribution, meaning, function and use of a discourse marker ‘i’ in the southwestern dialect of Korea, basing on Grammaticalization theory. ‘i’ is the dialect form corresponding to ‘eung’ of the standard language. However, ‘i’ got to be a discourse marker, as a grammaticalizaion process progressed. First, as the lexical meaning of ‘eung’ [positive] is bleached, at the beginging of a sentence, ‘i’ has the functions like taking speakers hour to think continuing dialogue and at the moment between sentential constituents and the final of a sentence, ‘i’ has the functions of expressing speaker’s emotional state like emphasis, assurance, intimacy, and covertness. Furthermore, ‘i’ is spoken fusing with the constituent which is front of ‘i’. This phenomenon is also under the influence of grammaticalizaion. In this paper, discourse marker is accounted for the outcome of grammaticalizaion. It means ‘i’ has the meanings and functions which are very similar to ones of tag question maker ‘i’ because of persistence mechanism. In this view, this paper also has typological consideration of tag question, and reconsider ‘i’ of the southwestern dialect of Korea. 본고에서는 문법화 이론을 토대로 서남방언 ‘이’의 통사론적 분포와 의미, 기능을 살피고자 하였다. 서남방언 ‘이’는 현대 중앙어의 ‘응’에 대응하는 방언형이다. 이 ‘응’은 의지감탄사이자 부가의문문 표지로 기능한다. 그런데 서남방언 ‘이’는 문법화가 진행되면서 현대 중앙어의 ‘응’과는 다른 면모를 보인다. 우선 ‘응’이 갖는 어휘적 의미인 [긍정]이 탈색되면서 문두에서 ‘이’는 시간 끌기와 같은 담화 전략을 위해 쓰이고, 문장 성분의 뒤나 문장의 마지막에서 ‘이’는 강조, 확신, 친밀감, 은밀함 따위의 화자의 감정 양상을 나타내는 데에 쓰인다. 또한 ‘이’는 앞 성분과 음운론적 휴지를 두지 않고 융합되어 발화된다. 이러한 현상 역시 문법화의 영향인 것으로 파악된다. 본고에서는 담화표지를 문법화의 산물로 보았고, 이때 의미지속성(persistence)이라는 문법화 기제로 인하여 담화표지 ‘이’에는 부가의문문 표지 ‘이’가 화용론적 맥락에 따라 해석되는 양상이 반영되고 있음을 보였다. 이런 관점 하에 부가의문문에 관한 유형론적 고찰을 행하였고, 이를 통해 서남방언 ‘이’를 재고하였다.

Ti계 생체이식금속의 구성 성분에 따른 물성과 세포독성에 관한 연구+

김태인,한준현,이인석,이규환,신명철,최부병 대한치과이식임플란트학회 1996 The Korean Academy of Implant Dentistry Vol.15 No.1

Today, dental implants are acceptable alternative capable of providing bone-anchored fixed prostheses for improved quality of life and self esteem for many patients. Research advances in dental implantology have led to the development of several different types of materials and it is anticipated that continued research will lead to advanced dental implant materials. Currently used pure titanium has relatively low hardness and strength which possibly limits its ability to resist functional load as a dental implant. Ti 一 6A1—4V also has potential problems such as corrosion resistance, bone biocompatibility etc. The carefully selected Zr, Nb, Ta, Pd, In constituents could improve mechanical strength, corrosion resistance and biocompatibility compared to that of currently used implant metals. On the basis of the totality of the data from our several experiments, it can be concluded that new titanium alloys contained Zr, Nb, Ta, Pd, In are able to provide improved mechanical properties, corrosion resistance and biocompatibility to warrant further investigation of it’s potential as a new biomaterials for dental implant.
