표준청각검사와 자기청력검사는 청력역치의 측정으로 난청의 종류를 구별하고 누가현상유무를 판정하며, 사청검사를 할 수 있는 공통점을 갖고 있다. 그러나 표준청력검사는 동일강도의 음을 부여하는 대신 자기청력검사는 음의 증강 및 감약이 계속되는 음을 부여하는 점이 양자의 상이점이다. 이런 차이로 인해 자기청력검사에는 일과성 역치 상승(temporary threshold shift)현상이 일어나 청력 역치가 높을 수 있다. 양자의 역치차가 각 청력군별로 어느 정도차이가 있는가를 관찰할 목적으로 정상청력군 50명 (100이), 전음성 난청군 41명(50이), 감각신경성 난청군 38명(50이)을 대상으로 표준 및 자기청력검사의 기도측정을 실시하여 양 검사의 차를 구하고 그 결과를 다음과 같이 요약하였다. 1) 정상청력군과 전음성 및 감각신경성 난청군 모두 자기역치가 표준역치 보다 높게 측정되는 경향으로 난청군에서 더욱 높게 측정되었다. 그러나 자기역치가 낮은 예도 많았다. 2) 양 검사의 일치범위를 $\pm$10㏈로 하면 정상 청력군은 94%, 전음성 난청군 85%, 감각신경성 난청군 79%에서 양 검사가 일치하였다. 3) 자기역치에서 표준역치를 추정할 수 있는 범위는 정상군에서는 5~-l0 ㏈, 난청군에서는 5~-15 ㏈ 의 변동폭이었다. 4) 양 검사의 역치차가 $\pm$20 ㏈이상인 예도 많아 양 검사는 서로 독립된 검사라고 생각되었다.

Purpose: The purpose of current study was to review the surgical treatment results in patients with a ganglion cyst involving peripheral nerves and to suggest the poor prognostic factor. Materials and Methods: Twelve patients having neurologic symptoms caused by ganglion cyst were treated operatively between 1995 and 2000. The peripheral nerves involved were the tibial nerve in three patients, suprascapular nerve, common peroneal nerve, radial nerve, and ulnar nerve in two patients each, and median nerve in one patient. Pain was present in six patients, sensory disturbance or motor weakness was seen in seven patients each; and sensory disturbance and motor weakness were concurrently present in four patients. Results: In all six patients who complained of preoperative pain, the pain was resolved after surgery. Improvements were seen in five of seven patients who had preoperative sensory disturbance and in all patients who had preoperative motor weakness. Complete sensory recovery was obtained in only two of four patients with preoperative sensory disturbance and motor weakness, indicating a poor prognosis factor. Conclusion: Early accurate diagnosis and early excision of these ganglion cysts causing compression neuropathy could produce excellent clinical results.

Purpose: To compare the clinical and radiological results of anterior cruciate ligament(ACL) reconstruction using hamstring autograft and tibialis tendon allograft. Materials and Methods: Twenty four ACL reconstructions using hamstring autograft and 30 using tibialis anterior tendon altograft were followed up at least 1 year. We performed femoral tunnel fixation with Ligament Anchor(LA) screw and tibial tunnel fixation with biodegradable interference screw. Evaluations included Lysholm knee(LK) score, Tegner activity scale, Lachman test, Pivot-Shift test, Quardriceps atrophy, incision site numbness, anterior knee pain and instrumented anterior laxity with $Telos^{(R)}$ device. Results: Preoperativ mean LK score was $60.3(18{\sim}82)$ in autograft group and 61.2(25-80) in allograft group. Mean LK score improved to $91.6(68{\sim}100)\;and\;92.6(77{\sim}100)$ respectively. Activity level, using Tegner activity scale, slightly decreased compared with that of Preinjury state in both groups. Lachman test, pivot-shift test, Quadriceps atrophy, anterior knee pain, incision site numbness, and anterior drawer test using $Telos^{(R)}$ device showed no significant difference between two groups (p>0.05). Conclusion: In performing the ACL reconstruction, there was no statistically significant difference between hamstring autograft group and tibilis anterior allograft group in clinical or in radiological results.

Purpose: Proprioceptive function has been known to be important to shoulder stability. However, the function in rotator cuff tear patients is rarely investigated. The purpose of current study is to report the proprioceptive function in rotator cuff tear patients and to analyze the proprioceptive function regarding the tear size and the presence of subscapularis tear. Materials and Methods: Between 2011 and 2012, total 76 patients (male 28 and female 48) were recruited and average age was 61.7 years old (range, 38~76). Preoperatively, joint position senses in internal and external rotation were measured for proprioceptive function testing by method of active re-positioning technique. The absolute difference from set point was measured. Proprioceptive function was further analyzed according to tear size of rotator cuff, the presence of subscapularis tear, visual analogue scale of pain, shoulder functional score (American society of elbow and shoulder score), and ranges of motion in shoulder. Results: The absolute difference for external rotation was $4.9^{\circ}{\pm}2.9^{\circ}$, in normal joint and $4.9^{\circ}{\pm}3.0^{\circ}$for involved joint in rotator cuff tear patients. This difference was not significant statistically (p=0.87). The absolute difference for internal rotation was $4.0^{\circ}{\pm}2.7^{\circ}$in normal joint whereas $4.8^{\circ}{\pm}3.7^{\circ}$ for involved joint showing statistically significant difference (p=0.043). There was some trend that the proprioceptive function of internal rotation was more impaired in the bigger tear size group (more than medium tear) compared to the smaller tear size group (partial thickness and small tear, 5.0 vs. 4.0, p=0.061). The impairment of internal rotation proprioception was also accentuated in patients with subscapularis tear (4.8 vs. 4.0, p=0.065). The proprioceptive function of internal rotation was decreased when the pain visual analogue scale was increased (5.2 vs. 4.0 p=0.04), shoulder functional score was decreased (6.1 vs. 4.2, p=0.005), or range of motion in shoulder joint was restricted (5.3 vs. 3.7, p=0.041). Conclusion: The deficit of proprioceptive function was observed in rotator cuff tear patients. Proprioception for internal rotation was impaired in patients with the bigger tear size and subscapularis tear. Pain, shoulder function score, and range of motion were also shown to be related with the deficit in proprioceptive function.

악취현상은 더 이상 대기오염물질에 한 형태가 아니며 또다른 하나의 감각공해라는 개념이 점차 확산되면서 악취에 대한 관심이 점차 고조되고 있다. 그러나 악취현상의 규명이 국내는 물론 국외에서도 충분한 근거를 제공받지 못하는 데에는 첫째, 대기환경 중에 악취물질은 약 40만종 이상이며, 각 물질의 최소감지 농도(threshold:역치) 값 자체가 수ppm∼수ppb 이하 수준이므로 물질농도를 정확히 규명하는 데에는 물질 고유의 특성과 더불어 상당한 수준의 기술과 장비가 요구된다. (중략)

A hemangioma at a cardiac valve leaflet is a rare finding. There are only five reported cases in the medical literature and no prior case reported in Korea. A previously healthy 45-year-old woman presented with an acute episode of numbness in the left side of the face and hand. Although no definite abnormalities were found on the neurological examination and testing the echocardiography revealed an echogenic mass in the anterior mitral valve leaflet. The tumor was excised en bloc from the leaflet and the defect was repaired with an autologous pericardial patch. Pathology examination confirmed the mass to be a hemangioma of the valve leaflet. Here we report this case and review the medical literature.

This study aimed to identify the correlation of stress-coping, humor sense, and adaptation to college of nursing students. Three hundred thirty eight subjects completed a structured questionnaire in June 2012. Data were analyzed using SPSS/WIN 21.0 program. The mean scores were as follows; stress-coping 43.33, humor sense 72.18, and adaptation to college 68.02. It meant beyond the intermediate level. Significant differences were found between adaptation to college scores and general characteristics such as gender, academic year, family type, economic status, campus life satisfaction, relation with faculties, grade, and the relationship with the opposite gender. There was significant but weak correlation of stress-coping, humor sense, and adaptation to college. These results suggest that it is necessary to develop individualized education programs considering students' characteristics. Additionally, university adjustment related factors should be studied.
