이재도 ( Jae-do Lee ),박명환 ( Myeong-hwan Park ) 한국고등직업교육학회 2009 한국고등직업교육학회논문집 Vol.10 No.1

This research targeted 940 students of the D-College as of 2008 to analyze individuals’ confidence in the selection of their major, question of career decision making as of the present, and obstacles for the career decision making by different variables. College students’ confidence on the selection of their major manifested significant difference depending on the gender, experience of whether they took additional year to take the College entrance exam again, question of career decision making and type of major. As for the verification on the level of confidence in career decision making, difference exists depending on the gender, question of career decision making, grade, age, hometown and type of major. When the College students’ confidence on the selection of their major increases, level of non-decision on their career decreases, and when the total level of obstacles for career decision makings high, perception of the non-decision on their career increases as well. Among the sub variables of the obstacles for career decision making, factors such as ‘lack of self assurance’, ‘sense of physical inferiority’, ‘difficulty in interpersonal relations’, ‘relationship with other important people’, ‘lack of information on occupation’ and ‘lack of interest’ affect non-decision on the career. Among the variables that influence, obstacles for career decision making that correspond to the ‘lack of self assurance’ is the highest in terms of influence, followed by the ‘lack of interest’ and ‘lack of information on occupation’.

대학생의 휴대폰 중독에 관한 연구(D 대학중심)

이재도(Jae-Do Lee) 한국컴퓨터정보학회 2007 韓國컴퓨터情報學會論文誌 Vol.12 No.4

본 연구는 D 대학 재학생 482명으로부터 설문조사하여 대학생의 휴대폰을 통해서 수신되는 스팸문자메시지의 정도 그리고 휴대폰 중독정도를 살펴보았다. 대학생들은 하루에 평균 스팸 문자메시지를 1번에서 2번 정도 수신하는 것으로 나타났다. 수신 스팸 메세지 중에서 상품광고에 대한 내용이 가장 많았고, 스팸 메세지는 거의 확인하지 않는 것으로 조사되었다. 휴대폰의 중독에 대해서는 응답자의 평균 중독점수는 100점 만점에 38.73점으로 나타났으며 60점 이상자 수는 47명으로 9.75%에 해당되며, 70점 이상자는 13명으로 2.70%에 해당되는 것으로 나타났다. 또한 학생들은 나이가 적을수록 그리고 기타지역 출신 학생이 중독적 집단에 많이 포함되어 있었고, 2년제 학생이 3년제 학생 보다 더 많은 학생이 중독적 집단에 많이 포함되어 있었다. This study executed questionnaire surveys on 482 undergraduates of D-college to review the extents of spam letter messages received through the mobile phones of college students and the extents of their addiction to mobile phones. It was revealed that each college student received one or two spam letter messages on average a day. Among the received spam messages were the messages containing the contents of commodity advertisements most frequent and the surveys indicated that spam messages are hardly read. As for the addiction to mobile phones, the average score of addiction of the respondents was indicated to be 38.73 based on the full score of 100 and the number of the ones with the scores of 60 or more was 47 which is 9.75% and the ones with the scores of 70 or more was 13 which is 2.70%. Also the younger the students were, the higher were the numbers of the students included in the addictive group and the number of students from other areas included in the addictive group was high and the number of the students in 2years system included in the addictive group was higher than the number of the students in 3years system included in the addictive group.

대학생의 중도탈락에 관한 연구(D대학 중심)

이재도,Lee, Jae-Do 한국정보컨버전스학회 2008 한국정보컨버전스학회논문지 Vol.1 No.1

본 연구는 대학생의 중도탈락에 대한 현황과 요인을 분석한 연구로서 D대학의 2001년부터 2005년에 입학한 학생 중에서 정원 외 전형으로 입학한 학생을 제외한 14,210명을 대상으로 하였다. 일반적 특성의 모든 항목에서 유의한 차이가 있는 것으로 나타났으며, 남학생이 여학생보다, 특별전형으로 입학한 학생이 일반전형으로 입학한 학생보다, 기타계열의 고교 출신자가 일반계 고등학교 졸업자보다 중도탈락률이 높게 나타났다. 중도탈락 학생들에 대한 분석에서는 미복학(40.16%)으로 인한 중도탈락이 가장 많았으며 다음으로 미등록(32.98%), 자퇴(25.05%), 학사제적(0.81%)으로 인한 중도탈락 순이었다. 전체 대상자의 중심경향 값에 따른 분포를 보면 학생부 성적과 결석일수는 정적편포이며 대학 성적은 부적편포로 낮은 점수를 받은 학생은 일부이고 대부분 높은 점수가 집중된 경향임을 나타내었다. 표준편차를 보면 학업지속자 보다 중도탈락자의 성적이 크게 나타나 비교적 학업지속자의 성적이 비슷한 것으로 보여 학생부성적과 결석일수 모두가 중도탈락에 영향을 미치는 것으로 나타났으며, 학생부성적이 낮을수록, 결석일수가 많을수록 중도탈락에 더 많은 영향을 미침을 알 수 있다. 대학 1학년1학기 성적을 제외한 나머지 성적이 낮을수록 중도탈락에 더 많은 영향을 미침을 알 수 있었고, 1학년 전체 성적이 제일 많은 영향을 미치고 다음이 1-2학기학점, 1-1학기 성적, 1-2학기성적, 그리고 1-1학기 학점 순으로 영향을 미치는 것으로 나타났다. 일반적 특성 항목에서는 수업년한이 제일 큰 영향을 미치고 다음이 성별이 미치며 나머지 항목들은 영향의 수준이 미미한 것으로 나타났다. This study analyzed the status and causes for the dropouts of college based on the survey conducted among 14,210 freshmen attending D College, other than the supernumerary special selection, from 2001 through 2005. A significant difference was shown in all items of general characteristics. The dropout rate of women, generally selected and general highschool graduated were higher than for men, specially selected and special high school graduated, respectively. The most dropouts were due to Not Return(40.16%), followed by Unenrolled(32.98%), Voluntary Leave(26.05%) and Expelled(0.81%) in order. In the distribution of the central tendency values measured from the entire subjects, the high school records and the days of absence showed a positive skewness, while the college records showed a negative skewness with the data mostly around a higher grade. The standard deviation indicating that the dropouts got the scores higher than those of the continuing students demonstrated that there was relatively insignificant difference in scores between two groups. It was demonstrated that both the high school records and the days of absence affected the dropout. The lower the high school records were, and the more the days of absence were, the more influence both items had on the dropout. The influence degree of each item was similar. Lower the scores were in terms other than the first term in the freshmen year, the more influence it had on the dropout. The most dropouts were influenced by the scores of the freshmen year, followed by the credits of the second term, the scores of the first term, the scores of the second term, and the credits of the first term in the freshmen year. Among the general characteristic items, the most dropouts were influenced by the course of study, followed by the gender. The effect of other items was insignificant.

이재도 ( Jae-do Lee ) 한국고등직업교육학회 2010 한국고등직업교육학회논문집 Vol.11 No.4

This research was conducted targeting 606 D College students to identify whether they have experience writing reply on the Internet to examine the types of Internet reply drafted motivation for drafting the reply, and whether they have experience drafting negative (malicious) reply. Moreover, this research examines the correlation between offensiveness and impulsiveness of the students who have or do not experience drafting malicious reply. As for the motivation for drafting the reply, male College students cited ‘no need to disclose the real name’ and 'drafting mitigates stress' while female College students cited ‘it is fun’ and ‘due to the personal emotion.’ reply of the students who have experience drafting reply, number of viable reply outweighed malicious reply. Male College students tended to draft more malicious repls compared to the female College students. There were more students who had experience drafting malicious reply at PC cafes or other places compared to their homes or public places. The students who cited ‘no need to disclose the real name’, ‘it is fun\ ‘due to the personal emotion’,‘due to the sense of heroism’ and ‘drafting mitigates stress” tended to have experienced drafting malicious reply more than other students. Offensiveness and impulsiveness of the students who had experience drafting malicious reply tended to be severe compared to the students who do not have such experience.

For the object-based video compression at very low bit rate, vieo segmentation is an essential part. In this paper, we propose a temporal video segmentation algorithms for motion pictures which is based on blocks. The algorithm is composed of three steps: (1) the change-detection, (2) the block merging, and (3) the block segmentation. The first step separates the change-detected region from background. Here, a new method for removing the uncovered region without motion estimation is presented. The second step, which is further divided into three substeps, estimates motions for the change-detected region and merges blocks with similar motions. The merging conditions for each substep as criteria are also given. The final step, the block segmentation, segments the boundary block that is excluded from the second step on a pixel basis. After describing our algorithm in detail, several experimental results along the processing order are shown step by step. The results demonstrate that the proposed algorithm removes the uncovered region effectively and produced objects that are segmented well.

주파수 변동시 불평형 전압에 강인한 DSC-PLL 설계 연구

이재도(Jae Do Lee),차한주(Han Ju Cha) 대한전기학회 2018 전기학회논문지 Vol.67 No.11

In this paper, the design of robust DSC-PLL(Delayed Signal Cancellation Phase Locked Loop) is proposed for coping with frequency variation. This method shows significant performance for detection of fundamental positive sequence component voltage when the grid voltage is polluted by grid unbalance and frequency variation. The feedback frequency estimation of DSC-PLL is tracking the drift in the phase by unbalance and frequency variation. The robust DSC PLL is to present the analysis on method and performance under frequency variations. These compensation algorithms can correct for discrepancies of changing the frequency within maximum 193[ms] and improve traditional DSC-PLL. Linear interpolation method is adopted to reduce the discretized errors in the digital implementation of the PLL. For verification of robust characteristic, PLL methods are implemented on FPGA with a discrete fixed point based. The proposed method is validated by both Matlab/Simulink and experimental results based on FPGA(XC7Z030).
