We have usually experienced bone conduction impairment in chronic otitis media, but it is unclear that raised bone conduction threshold is due to the reflection of cochlear dam- age and / or Carhart effect ( an artificial elevation of bone conduction threshold due to conductive defect ) or both. The purpose of this study is to verify the influence of the artificial elevation of the bone conduction threshold in chronic otitis media and to estimate Carhart effect. A total of 336 cases of tympanoplasty with unilateral chronic otitis media without any other causes of sensorineural hearing loss was studied. The average threshold levels of the bone conduction in diseased ears ranged from 18.5dB at 4kHz to 12.1dB at 250Hz The longer duration of the disease, the larger perforation size, the more severe damage of the middle ear structure and the presence of the cholesteatoma made bone conduction threshold increased. The postoperative thresholds of bone conduction were Improved in 36 cases (40.4%) of the 89 cases that underwent operation with type I tympanoplasty technique without electrie drilling. The degree of the maximal improvement was 14.3dB at 2000Hz and the minimum was 8.8dB at 250Hz. but these result did differ from a statistically significant degree. The result suggest that the bone conduction threshold in chronic otitis media is elevated artificially by conductive defect and improved by successful reconstructive surgery.

This study is a experiment on the mechanical properties of concrete according to the fiber additional quantity of bamboo. The experiment and analysis results are as the following. The slump as a quality of the concrete not to harden showed to decrease more remarkably for a slump value than the plain according to the increment of cellulose additional rate. Air quantity showed to increase only in 0.2% fiber additional rate and to get out of KS allowable error of bad air content in 0.4% and 0.6%, and capacity mass by unit showed a reverse tendency against air quantity according to the change of cellulose additional quantity. Compression intensity as a quality of hardening concrete showed collectively a tendency to decrease in the remnant past days except only 0.6% at the standard past day 愀8 and the initial 3 days. Pulling intensity showed to increase more than the plain in all past days according to the change of fiber additional quantity of bamboo, and bending intensity also showed to be higher revelation intensity than the plain in the measurement result at the standard past day 28. In the result of length change rate, we can find the bigger the cellulose additional rate as a special quality increased, the more it decreased according to the pass of the past day.

본 연구는 1990년부터 1994년까지 인제대학교 의과대학 상계백병원 신경정신과에서 치료받았던 환자 중, 두부 외상의 기왕력이 있고, ICD-9의 뇌진탕후 증후군의 진단기준을 만족하는 환자 28명과 무작위로 선정된 32명의 신경증 대조군에게 시행했던 K-WAIS alc MMPI의 결과로, 두 집단을 비교하여 다음과 같은 결과를 얻었다. 1) 인구동태학적 지표에서 뇌진탕후 증후군 집단이 신경증 대조군에 비해 평균 연령, 교육 연한에서 의미있는 차이를 보였다. 2) 한국판 웩슬러지능검사(K-WAIS)에서 뇌진탕후 증후군 집단이 언어성 검사 중 기본 지식 문제와 숫자 외우기, 어휘 문제, 동작성 검사중 빠진곳 찾기, 바꿔쓰기에서 보통 범위 이하의 점수를 보였으나 신경증 대조군 집단은 보통범위 이상의 점수를 보였다. 3) 다면적 인성 검사(MMPI)에서 뇌진탕후 증후군 집단은 타당도 척도에서 역전된 V자형을 보였고, 하위척도 중 Hs척도가 의미있게 높은 결과를 보였다. 4) 뇌진탕후 증후군 집단의 군집 분석에서 첫번째 군은 타당도 척도에서 낮은 정도의 V자형을 보였고 Hs척도가 상승하였고, 두번째 군은 타당도 척도에서 역전된 V자형을 보였고 하위척도중 Hs, D, Pa, Pt, Sc척도가 의미있는 상승을 보였다. 이상의 결과로 보아, 뇌진탕후 증후군 환자들은 신경증 대조군 환자들과 비교하였을때 자신의 증상으로 인한 정서적인 고통을 많이 받을 뿐만 아니라, 인지 기능상의 손상이 심함을 알 수 있었다. Object : This study was conducted to investigate the clinicopsychological characteristics of patients with postconcussional syndrome. Methods : K-WAIS and MMPI were applied to 28 patients with postconcussional syndrome and 32 random-sampled neurotic controls. The means between two group were compared by ANCOVA. Cluster analysis was also applied to T-scores of the MMPI in patients with postconcussional syndrome. Result : 1. In demographic data, there were significant differences in mean age and education period between postconcussional syndrome group and the control group. 2. In postconcussional syndrome, Information, Arithmatics, Vocabulary and Picture Completion and Digit Symbol scores of K-WAIS were lower than that of mean score. 3. In MMPI profiles, reliability scale was inverted ‘V’pattern, and Hs scale was highly significant for postconcussional syndrome. 4. In postconcussional syndrome, cluster analysis was applied to each subscale of the T-score of MMPI, and two subgroups were extracted. 1) The first subgroup showed that reliability scale was low V pattern, and Hs scale elevated. 2) The second subgroup showed that reliability scale was inverted V pattern, and Hs, D, Pa, Pt, Sc scale elevated significantly. Conclusion : The patients with postconcussional syndrome were more severely ill, not only in emotional distress but also in cognitive dysfunction, than that of neurosis control.

『搜神記』연구(1)

This study aims at identifying the genre and type of 'Sushinki'. The author, Kanbo(于寶), wrote and edited 'Sushinki', based upon his collection of materials that had been long compiled in a marrer that is consistent with his belief in literature. He pursued the pleasure of literature by bringing in such issues as going beyond the empirical world slinging into the realm of God. He created this work based on both written and orally inherited narratives, which is classified as podigious narratives. This work is composed of 464 pieces of which 158 episodes are about good and bad omens, 53 episodes are about unveiling a creature of metamorphosis, and 50 episodes are about mystic immortal hermits in the mountains. All of these pieces well represent the psyche of Chinese from the 4th century who had aspirations of anticipating the future due to the uncertainties caused by dialing was and escaping from the world by spiritual practice. This work is typical of its romantic attributes as represented by the depiction of natural - born super heroess, disciplined figures with clairvoyant capabilities, spiritualistic figures communicating with God, superhuman characters who attain extraordinary power after experiencing death a sense of karma, changes and omens, resuscitation·metamorphosis·paradise, stories about human will or Gods intervention errors, and bad luck Considering the authors perspective, the storyteller has an Animistic view on the world, projecting the principle of change and rejuvenation based on a cyclic structure. In this study, 'Sushinki' is compared with Korean narratives to identify she genealogy or differences between this works Shamanistic narrative with relevance to Taoism and its Korean counterparts.
