This paper developed systematically the theory of Integral Expression using and based on set, and examined the relation of equality. Introducing the four rules of arithmetic operation on the basis of set theory and examining their properties, or this paper constructed a system of integral Expression, by introducing. I hope this paper will help think logically in using the Integral Expression and grope for desirable teaching method.
李鍾傑 忠州大學校 1999 한국교통대학교 논문집 Vol.34 No.1
This paper has developed systematically the theory of continuous function based on the set theory, and examined the relation of uniformity. The theory analyzed the continuum of limit closely by converting the limit concept into function. I hope this paper will enable the reader to think logically when using the continuous function and find a desirable teaching method.

This paper developed systematically the theory of Fractional Expression using and based on set, and examined the relation of equality. Introducing the four rules of arithmetic operation on the basis of set theory and examining their properties, this paper constructed a system of Fractional Expression. I hope this paper will help think logically in using the Fractional Expression and grope for desirable teaching method.

This paper developed systematically the theory of Complex number using based on set, and examined the relation of equality. Introducing the four rules of arithmetic operation on the basis of set theory and examining their properties, this paper constructed a system of Complex number. I hope this paper will hope do logical thinking in using the Complex number and grope for desirable teaching method.
李鍾傑 忠州大學校 1989 한국교통대학교 논문집 Vol.23 No.-
In this paper I developed the process of functional concept of superior limit and inferior limit. The contents are as follows: 1) I defined the meaning of limit point by introducing [ε→δ] into the limit concept [χ→α], to lead the concept of upper bound, lower bound, and sup. inf. 2) During the set operation I derived the monotone increasing sequence of sets from the fact that intersection-set is akin the G.C.M in number and of the monotone decreasing sequence of sets from the fact that union-set is akin to L.C.M in number. 3) It is bounded that I can introduce limit from the sequence of sets.

This paper developed systematically the theory of Symmetric Expression using and based on set, and examined the relation of equality. Introducing the four rules of arithmetic operation on the basis of set theory and examining their properties, this paper constructed a system of Symmetric Expression. I hope this paper will help think logically in using the Symmetric Expression and grope for desirable teaching method.
李鍾傑 忠州大學校 1986 한국교통대학교 논문집 Vol.20 No.1
This paper developed systematically the theory of integer using axiom based on set, and examied the relation of eguality. Introducing the found rules of arithmetic operation on the basis of set theory and examining their properties, this paper constructed a system of integer. I hope this paper Will help do logical thinking in using the integer and grope for desirable teaching method.

In 1986, R. Huff [3] showed that a Dunford integrable function is Pettis integrable if and only if T : X??→L(μ) is weakly compact operator and {T(K(F,ε))|F⊂X,F : finite and ε>0}={0}. In this paper, we introduce the notion of Bourgain property of real valued functions formulated by J.Bourgain [2]. We show that the class of pettis integrable functions is linear space and if f is bounded function with Bourgain property, then T : X??→L(μ) by T(x??)=X??f is weak??-to-weak linear operator. Also, If operator T : L(μ)→X?? with Bourgain property, then show that T is Pettis representable.

Background: The isolation of non-tuberculous mycobacteria (NTM) has been increasing worldwide. The aim of this study is to investigate the isolation rate of NTM and clinical significance of NTM during recent 2 years. Methods: We retrospectively analyzed all acid-fast bacilli (AFB) culture positive specimens collected at Yeungnam university hospital, between January 2012 and December 2013. Results: During the recent 2 years, culture of 11,672 specimens were requested from 6685 patients. Total of 1314 (11.3%) specimens resulted in culture-positive for AFB, among which 587 (44.7%) specimens from 382 patients revealed NTM. (six of the specimens were non-respiratory specimen, such as joint fiuid, Cerebrospinal fiuid) Among the NTM culture positive patients, 50.5% (193/382) were female and the average age was 65.3 years. Identification of NTM species was con. rmed in 172 patient. The most frequently isolated species were mycobacterium avium complex (MAC) which was derived from 123 patient (71.5%). M. intracellulare was isolated in 99 patients and M. avium in 24 patients, followed by M. abscessus (20 patient, 11.6%), M. kansasii (12 patient, 7.0%), M. fortuitum (10 patient, 5.8%), M. gordonae (9 patient, 5.2%). Among 382 patients, 167 (43.7%) patients were diagnosed with NTM lung disease and 66 (39.5%) of them were treated. Conclusions: The recovery rate of NTM isolate was relatively high during very recent 2 years in our hospital. This result refiect the increasing tendency of NTM isolation.
