        전문대학 공학계열 학생의 기초학습능력 수준에 따른 학업성취도 결과 사례연구: I 전문대학 사례를 중심으로

        한성일(Sung-Il Han),강문상(Moon-Sang Kang) 한국공학교육학회 2012 공학교육연구 Vol.15 No.5

        The influences of the basic academic skills to the scholastic achievement grades has been researched and we made a test of the basic academic skills(Korean language, mathematic, foreign language) to the students of engineering department in I college in Seoul and analyzed the correlation between the basic academic skills and the scholastic achievement grades. Results show that the scholastic achievement grades has a correlation(r=.456, p<0.01) to the average grade of the basic academic skill test. High level students of the scholastic achievement grades have a correlation(r=.292, p<0.01) to the mathematical department and the others have a correlation(r=.232, p<0.05 and r=.279, p<0.01) to the Korean linguistic department. The results of this study through multiple regression analysis indicate that the scholastic achievement has a relation on Korean language skill. As a result, It is recommendable that the mathematical basic academic skill programs are suggested to the high-level students of the scholastic achievement grades and the linguistic basic academic skill programs to the others. Also, the required basic linguistic subject is needed to the low-level students of the basic academic skills and in this paper, we propose the test and management system for the basic campus-life skills including the basic academic skills and the basic major skills.

      • 2진-4치 변환기 설계에 관한 연구

        한성,이호경,이종학,김흥수 대한전자공학회 2003 電子工學會論文誌-SC (System and control) Vol.40 No.3

        본 논문에서는 전압모드를 기초로 한 2진-4치 상호 변환기와 논리 게이트의 기본 소자라고 할 수 있는 4치 인버터회로를 설계하였다. 2진-4치 변환기는 2비트의 2진 신호를 입력으로 하여 1디지트의 4치 신호를 출력하는 회로이고 4치-2진 변환기는 1디지트의 4치 신호를 받아들여 2비트의 2진 신호를 출력하는 회로이며 Down-literal Circuit(DLC)블록과 2진 조합회로(CLC : Combinational Logic Circuit)블록으로 구성된다. 4치 인버터회로를 구현함에 있어서는 기준전압 생성 및 제어신호 생성을 모두 DLC를 사용하고 스위치 부분만을 일반 MOS로 사용하여 설계하였다. 설계된 회로들은 +3V 단일 공급 전원에서 0.35㎛ N-well doubly-poly four-metal CMOS technology의 파라미터를 사용한 Hspice를 이용하여 모의 실험을 하였다. 모의 실험 결과는 샘플링 레이트가 250MHz, 소비 전력은 0.6mW, 출력은 0.1V이내의 범위에서 전압레벨을 유지하는 결과를 보였다. In this paper, Binary to Quaternary Converter(BQC), Quaternary to Binary Converter(QBC) and Quaternary inverter circuit, which is the basic logic gate, have been proposed based on voltage mode. The BQC converts the two bit input binary signals to one digit quaternary output signal. The QBC converts the one digit quaternary input signal to two bit binary output signals. And two circuits consist of Down-literal circuit(DLC) and combinational logic block(CLC). In the implementation of quaternary inverter circuit, DLC is used for reference voltage generation and control signal, only switch part is implemented with conventional MOS transistors. The proposed circuits are simulated in 0.35 ${\mu}{\textrm}{m}$ N-well doubly-poly four-metal CMOS technology with a single +3V supply voltage. Simulation results of these circuit show 250MHz sampling rate, 0.6mW power consumption and maintain output voltage level in 0.1V.

      • Volume Rendering CT Image의 TACE Reference Data로서의 유용성

        한성일(Seong Il Han),나상훈(Sang Hun Na),김종옥(Jong Ok Kim),이제호(Jae Ho Lee),김성배(Seong Bae Kim) 대한CT영상기술학회 2010 대한CT영상기술학회지 Vol.12 No.1

        Purpose Transcatheter arterial chemoembolization(TACE) have a treating objective by inserting the angiography catheter in the hepatic artery that supplies blood to the hepatocellular carcinoma(HCC) and by this it can mix up the injection of carcinostatis and embolus substances to necrosis the liver cancer organisms. Typically a computed tomography(CT) decoding result was used as a treating plan by the doctor before transcatheter arterial chemoembolization was preceded but because of false classifications and the increased time of surgical operations, the anti-cancer medicine can be used in places that are not needed which bring out great pains to the patients. This investigation has been made so that confusions can be decreased when using the vascular volume rendering data that has been created in the 3 dimensional-lab. Materials and methods From a total of 1,144 cases that has used TACE at the National Cancer Center from June 1st, 2008 to August 5th, 2009, 50 HCC patients(43 men, 7 women with the average age being 58.18 years old ranging from 34 to 78 years) that converted their examined liver dynamic computed tomography’s artery phase image to a volume rendering image were evaluated by two decoding doctors and one radiologic technologist. Results The investigated patients were classified into four types. Type 1 was decoded that there was each lesion in the segment 5 through the segment 8 of the right lobe of liver according to CT test, but there was a lesion in other segment in case of TACE procedure. In other words, it meant that the segmentation was different in the right volume of liver. Type 2 was decoded that there was a lesion in the segment 4 according to CT test, but there was a lesion in the segment 8 in case of TACE procedure. In other words, is meant that the segmentation was different in the liver dome. Type 3 was decoded mat there was a lesion in me multiple segments or the single segment according to CT test, but there was a lesion in the single segment or the multiple segments in case of TACE procedure. And type 4 was the case that the results of decoding cannot be same or different in CT test and TACE procedure. Conclusion The hepatic artery’s shape in anterio-posterior conditions and the hepatic artery in right anterio-oblique Md left anterio-oblique conditions showed a significant difference. The blood vessels that seemed to be reiterated in AP conditions could be clearly classified by the change of angles in the right anterio-oblique and left anterio-oblique.

        프로스포츠 구단의 IMC활동이 관람의도에 미치는 영향

        한성은(Han, Seong-Eun),한진욱(Han, Jin-Wook),윤지인(Yoon, Jee-In) 한국사회체육학회 2017 한국사회체육학회지 Vol.0 No.70

        The purpose of this study is to investigate a mediating effect of team image and relationship quality between IMC activities of professional sport team and spectator intention to visit a game. To accomplish the purpose of the study, a total of 300 spectators who visit the Suwon kt wiz park were conveniently selected and responded to a survey questionnaire. 272 usable data were utilized in the data analysis procedure. Data were analyzed using frequency analysis, confirmatory factor analysis, reliabitliy analysis, descriptive analysis, correlation analysis and structural equation model. The results of the study indicaetd that there were partial mediating effects of team image and relationship quality on the relation between IMC activity and spectator intention to visit a game. Discussion and additional implications are also suggested.
