이상돈,이해균 한국시각장애교육&재활학회 2010 시각장애연구 Vol.26 No.4
The purpose of this study is to survey visually impaired goalball players’ awareness about referees who are responsible for coordination of goalball matches; determine potential effects of referees’ judgments upon actual goalball match; deduce potential complainable factors and issues in various judgment situations of referees; and explore into possible positive ways to restore a relationship of trust between players and referees in the interest of developing goalball. In order to achieve these goals, this study used a restructured questionnaire to survey total 86 goalball players who participated in a visually impaired goalball tournament of the 28th National Games for the Disabled in Korea. And all survey data collected from them were statistically processed and analyzed to meet the goals of study. As a result, this study could come to the following conclusions:First, according to analysis on our visually impaired goalball players’ awareness about referees depending upon their sex, it is found that female players have a tendency toward higher awareness on reliability of referees than male ones, whereas male players have a tendency toward higher awareness on fairness and influence of referees than female ones. Secondly, according to analysis on visually impaired goalball players’ awareness about referees depending upon their match results, it is found that runner-up and 4th- or lower-ranking team players have a tendency toward to higher awareness on the promptness of referees than champion team players; champion, runner-up and 4th- or lower-ranking team players have a tendency toward to higher awareness on the reliability of referees than 3rd-ranking ones; and runner-up, 3rd- and 4th- or lower-ranking team players have a tendency toward to higher awareness on the fairness of referees than champion ones. Thirdly, according to analysis on visually impaired goalball players’ awareness about referees depending on their goalball career, it is found that 6-year or longer career group has a tendency toward to higher awareness about the influence of referees than 1-year or shorter career group. Fourthly, according to analysis on visually impaired goalball players’ awareness about referees depending on whether they ever have experiences in unfair judgment of referees, it is found that ‘unexperienced’ group has a tendency toward higher awareness on reliability and specialty of referees than ‘experienced’ group, while ‘experienced’ group has a tendency toward higher awareness on the influence of referees than ‘unexperienced’ group. Finally, according to analysis on visually impaired goalball players’ awareness about referees depending on their age, it is found that all of three age groups have a tendency toward ‘moderate’ or higher awareness about referees, but there is no significant difference among groups. 본 연구의 목적은 시각장애 골볼 선수들의 심판들에 대한 인식을 조사하여 심판 판정이 경기에 미치는 영향과 다양한 심판의 판정 상황에 대한 불만족 요인 및 문제점을 추출하고 그에 따른 선수와 심판 상호간의 신뢰회복과 경기 발전을 위한 개선책을 모색하는데 있다. 연구는 제28회 전국장애인체육대회 골볼 경기에 참가한 선수 86명을 대상으로 실시하였으며, 그 결론은 다음과 같다. 첫째, 시각장애 골볼 선수의 성별에 따른 심판에 대한 인식은 신뢰성에서는 여자선수가 남자선수보다 높으나, 공정성과 영향력에서는 남자 선수가 여자선수보다 높다. 둘째, 시각장애 골볼 선수의 경기성적에 따른 심판에 대한 인식은 신속성에서는 준우승, 4위 이하가 우승보다 높고, 신뢰성에서는 우승, 준우승, 4위 이하가 3위보다 높으며, 공정성에서는 준우승, 3위, 4위 이하가 우승보다 높다. 셋째, 시각장애 골볼 선수의 선수경력에 따른 심판에 대한 인식은 영향력에서 6년 이상인 집단이 1년 미만인 집단보다 높다. 넷째, 시각장애 골볼 선수의 부당한 판정경험 유무에 따른 심판에 대한 인식은 신뢰성과 전문성에서는 ‘없다’가 ‘있다’ 보다 높으나, 영향력에서는 ‘있다’가 ‘없다’ 보다 높다. 다섯째, 시각장애 골볼 선수의 연령에 따른 심판에 대한 인식은 세 집단 모두 ‘보통’ 이상의 인식을 보이고 있으나, 집단간 차이는 없다.

Pantographic Reproducibility Index(PRI)를 이용한 하악운동의 재현성에 관한 연구
이상돈,박찬운,Lee, Sang-Don,Park, Charn-Woon 대한치과보철학회 1986 대한치과보철학회지 Vol.24 No.1
In order to determine if a relationship exists between the clinical symptoms of TMJ dysfunction and the reproducibility of mandibular movements, twenty one subjects were chosen. The control group consisted of 5 subjects who were determined to be free from signs and symptoms of dysfunction . The sixteen experimental subjects were selected on the basis of their having dysfunctional symptoms. The author obtained two sets of pantographic tracings. Each set consisted of tracings from three both lateral and one protrusive movements. A second set of tracings were recorded immediately on the new recording papers using the same procedure as the first tracing. The tracings were scored by Pantographic reproducibility index (PRI). The obtained results were as follows. 1. Mean PRI scores of groups increased as the degree of dysfunction were increased. 2. For the groups of no or slight dysfunctional symptoms the PRI scores of the second tracing were smaller than the first one, wherea the scores of the second tracing from $D_2,\;D_3$ group were larger than the first tracing. 3. Differences between the mean PRI scores of control group and those of experimental group were statistically significant. 4. The second sets of tracings were more reliable statistically than those of first ones. 5. PRI can be used as a meaningful aid for the evaluation of the diagnostic and therapeutic results of treatment modalities for the TMJ dysfunction. 6. At 3east two sets of tracings should be recorded when the PRI is to be used to detect the incoordinated movements of TMJ dysfunction patient. 7. PRI scores of control group ($D_0$) was 137.7, thus, mandibular movement was reproducible, whereas PRI scores of experimental groups ($D_1,\;D_2,\;D_3$) were 22.5, 27.7, 30.45 respectively, thus were nonreproducible.

증착시 도핑된 비정질 Si 게이트를 갖는 MOS 캐패시터와 트랜지스터의 전기적 특성
이상돈,이현창,김재성,김봉렬 대한전자공학회 1994 전자공학회논문지-A Vol.31 No.6
In this paper, The electrical properties of MOS capacitors and transistoras with gate of in-situ doped amorphous Si and poly Si doped by POCI$_3$. Under constant current F-N stress, MOS capacitors with in-situ doped amorphous Si gate have shown the best resistance to degradation in reliabilty properties such as increase of leakage current, shift of gate voltage (V$_{g}$). shift of flat band voltage (V$_{fb}$) and charge to breakdown(Q$_{bd}$). Also, MOSFETs with in-situ doped amorphous Si gate have shown to have less degradation in transistor properties such as threshold voltage, transconductance and drain current. These improvements observed in MOS devices with in-situ doped amorphous Si gate is attributed to less local thinning spots at the gate/SiO$_2$ interface, caused by the large grain size and the smoothness of the surface at the gate/SiO$_2$ interface.
