Objectives : The purpose of this study is to analyze the factors associated with respirator usage on the basis of reasoned action theory. Methods : The data were collected from August 1 to September 30 1999, and study subjects consisted of 303 workers who were employed in the manufacturing industries. A self-administered questionnaire was used to measure the attitude, subjective norm and related factors. Results : In bivariate analysis, the variables related to protector usage were prevention of occupational disease, protection of toxic material, disturbance during working, troublesome of usage, proper exchange of protector. Multivariate logit analysis was used to estimate factors associated with respirator usage. Significant predictors that are related to respirator usage were attitude toward the behavior, size of industry and proper exchange of protector. Conclusions : The results suggest that it is strongly required to focus on attitude toward the behavior in order to improve workers' usage of respirator.

Objectives: Lateral cephalometry, computed tomography (CT) and full-night polysomnography were used to examine the correlation of obstructive sleep apnea (OSA) severity. Materials and Methods: A total of 29 patients (5 females, 24 males) diagnosed with OSA were evaluated by lateral cephalometry, CT and full-night polysomnography. Lateral cephalometry was performed in the closed and open mouth states. The radiographic and polysomnography measurements of the patients with OSA were evaluated statistically to determine the association with OSA severity. Results: A significant relationship was observed between the increased respiratory disturbance index and closing lateral cephalometry. With mouth opening, the airway space narrowed and the OSA worsened. Lateral cephalometry revealed OSA patients to have an inferiorly positioned hyoid bone, longer-than-normal soft palate and narrowing airway space. As OSA was severe, the airway shape was ovoid in the CT horizontal view. Conclusion: Polysomnography and the radiographic parameter can be used for diagnosing OSA.

Obstructive sleep apnea syndrome(OSAS) is most frequently diagnosed in the sleep laboratories and its severity is objectively estimated. In terms of treatment, the most prevalent method is the continuous positive airway pressure(CPAP) application as of now. However, in Korea, CPAP is still not sufficiently known and it is attributable to the fact that sleep study facilities have not been popularized. In this article, the authors present their own experience with CPAP in nine subjects with OSAS. In this study, CPAP was found to decrease stage 1 sleep and to increase stage 2 sleep, with increasing mean oxygen saturation and decreasing lowest oxygen saturation during nocturnal sleep. Also, it tended to increase sleep continuity and generally to improve sleep architecture. Rebound slow wave and/or REM sleep stages during CPAP were also noted in 8 out of 9 cases. The authors suggest that CPAP should be considered as the primary mode of treatment for patients with obstructive sleep apnea syndrome and related educational programs for physicians should be developed and provided by sleep specialists.

Tetrodotoxin (TTX) is the purified active principle responsible for tetrodon (Puffer-fish) poisoning which has long been known in the Orient. The pharmacological actions of TTX have been rather extensively investigated. Two of the most prominent effects of intravenousely administered TTX are severe hypotension and respiratory paralysis resulting from its depressant actions on tissues. This depressant actions of TTX in turn result from the selective inhibition of sodium-carrying mechanism which is essential to generation of the action potential. TTX differs from local anesthetics in that it does not affect potassium conductance. Although the mechanism of the hypotensive action of TTX remains a subject of controversy, most investigator agree that TTX-induced hypotension is caused by alteration in the blood vessels rather than the heart. Not only the study on the effects of TTX on cardiac function is meager but the results of reported works are often contradictory. The present study was undertaken to investigate the effect of TTX on the electrocardiogram of the rabbit and to compare them with well known electrocardiographical characteristics found in digitalis and quinidine intoxicated animals. The results obtained from the present study are summarized as follows. 1. No changes were found in P-R interval and QRS duration after i.v. administration of $1.0\;{\mu}g/kg\;to\;1.5\;{\mu}g/kg$ TTX to the animals. It is obvious that there were no conduction disturbance between atria and ventricles as well as in the ventricular tissue. 2. In $1.0\;{\mu}g/kg$ TTX group, S-T interval and T-P segment were not changed whereas marked changes were observed in $1.5\;{\mu}g/kg$ TTX group. 3. The first and second degree A-V blocks appeared in the $2.0\;{\mu}g/kg$ TTX group. 4. TTX differs from digitalis and quinidine in that it does not cause S-T interval depression and T-wave inversion. In contrast with digitalis, TTX caused Q-T interval prolongation.

The congenital epulis of newborn is a rare benign tumor that occurs on the gingiva of the anterior alveolar ridge of the jaws, also known as a congenital granular cell tumor. Females are affected 8 - 10 times more often than males. The typical location is the alveolar ridge of the maxilla near the canine but the mandibular region can also be involved. The lesion may be sessile or pedunculated with red or normal color. The size of tumor varies from several millimeters to a few centimeters in diameter. Surgical excision is generally indicated and no recurrences have been noticed. Spontaneous regression is rare. It is histologically similar to the granular cell tumor, although pseudoepitheliomatous hyperplasia does not occur in the former lesion. Thus sheets of large, closely packed cells showing fine, granular, eosinophilic cytoplasm comprise the tumor mass. This is a case report of congenital epulis in the fetus. The lesion was detected in ultrasonogram, its size is 3cm in diameter. The infant showed nursing disturbance and respiratory obstruction after birth, so the tumor was surgically excised under local anesthesia.

우리의 일상생활에서 양질의 수면은 행복 지수와 밀접한 관계가 있다. 사람들은 수면 장애를 만성 질환으로 인식하든 아니든 많은 어려움을 호소하고 있으며 일상생활에서 수면 중에 호흡 곤란을 경험하는 경우가 종종 발생한다. 수면 중에 호흡 관련 장애를 자동으로 인식하는 것은 매우 중요하나 현실적으로 매우 어렵다. 본 논문은 이러한 문제를 해결하기 위해 가정에서 건강관리를 위해 모바일 기반의 비접촉 수면 모니터링을 제안한다. 수면 중 호흡 신호는 스마트 폰의 소리 센서를 이용하여 호흡 신호를 수집하고, 신호의 특징을 추출, 호흡의 주파수, 진폭, 호흡의 주기, 호흡의 패턴을 분석한다. 모바일 건강이 모든 문제를 해결하지는 못하나 개인의 건강 상태의 조기 발견과 지속적인 관리를 목적으로 하고, 일반 가정의 침실에서 스마트 폰으로 추가 센서 없이 수면 중에 호흡과 같은 생리학적 데이터 모니터링의 가능성을 보여준다.

목 적 : 폐쇄성 수면무호흡증(이하 수면무호흡증) 환자에서 고혈압이 흔히 병발되나 지속적 상기도 양압술(이하 양압술)에 따른 고혈압 해소 정도는 연구방법에 따라 상이한 결과를 보이고 있다. 이에 저자들은 지속적-비관혈적 혈압 측정법을 이용하여 기초 혈압치가 다양한 수면무호흡증 환자군에서 양압술을 적용하면서 야간 수면중 혈압 및 심박 동수 반응에 양압술이 미치는 영향을 연구하고자 하였다. 또한 양압술에 의한 혈역학적 변화에 영향을 줄 수 있는 요인들을 찾고자 하였다. 방 법 : 연구대상으로는 수면무호흡증의 임상 증상을 지니고 있으며 기초 측정일의 야간 수면다원검사 결과 호흡장애지수가 5이상인 환자 10명(평균연령 52.2$\pm$12.4세, 남자 9명, 여자 1명)을 선택하였다. 양압술을 시행하지 않은 상태인 기초 측정일과 양압술을 시행한 양압술 시행일 모두에서 야간 수면다원기록과 동시에 지속적-비관혈적 혈압측정기($Finapres^{(R)}$)를 사용하여 매 박동(beat-to-beat)시의 수축기 혈압, 이완기 혈압, 그리고 심박동수를 측정하였다. 또한 매 2초마다 혈중산소포화도($SaO_2$)를 측정하였다. 기초 측정일과 양압술 시행일 두 군간에 혈역학적 및 호흡기적 변인들의 평균치를 비교하였다. 기초 측정일 값에서 양압술 시행일 값을 뺀 수축기 혈압 델타값 및 이완기 혈압 델타값 각각과 기초 측정일의 측정치들(수축기 혈압, 이완기 혈압, 그 각각의 혈압 변이도, 심박동수 및 심박동수 변이도, 혈중산소포화도 평균치, 그리고 호흡장애지수), 양압술 시행일의 측정치들(양압술 처방압력 및 총 각성시간 분율), 연령, 그리고 비만도 간의 상관관계를 분석하였다. 결 과 : 1) 혈중 산소포화도의 평균치와 호흡장애지수가 기초 측정일에 비해 양압술 시행일에서 각각 증가(p<.01) 및 감소(p<.01)하였으나, 혈역학적 변인을 포함한 다른 비교 변인들에서는 차이가 없었다. 2) 기초 측정일의 혈압에서 양압술 시행일의 혈압을 뺀 델타값들을 분석한 결과 기초 측정일의 혈압치와 대상군의 연령에 따라 혈압 반응이 차별적으로 나타났다. 수축기 혈압 델타값과 기초 측정일의 수축기 혈압간에 유의한 정적 상관관계를 보였으나(p<.01), 이완기 혈압 델타값과 기초 측정일의 이완기 혈압간에는 각성기(p<.01)를 제외한 다른 수면단계에서 유의한 상관관계가 없었다. 렘수면단계를 제외한 모든 수면단계에서 이완기 혈압의 델타값과 연령 사이에 유의한 역 상관관계가 있었지만(p<.05), 수축기 혈압의 델타값과 연령 간에는 유의한 상관관계가 없었다. 3) 수축기 혈압 델타값 및 이완기 혈압델타값 각각과 기초 측정일의 측정치들, 양압술 시행일의 측정치들, 그리고 비만도 간의 상관관계를 분석한 결과, 이완기 혈압 델타값과 양압술 시행일의 각성시간 분율간의 유의한 정적 상관관계(p<.01) 외에는 유의한 상관관계가 없었다. 결 론 : 양압술 적용에 따라 수축기 혈압 델타값과 이완기 혈압 델타값이 기초 측정일의 수축기 혈압치와 대상군의 연령에 따라 각각 증가 또는 감소하였다. 따라서, 본 연구는 양압술에 따른 혈압 반응은 단순 감소로 나타나는 것이 아니라 여러 변인의 조건에 따라 차별적 혈압 반응 양상으로 나타나는 복합적인 현상이며 앞으로 좀더 세밀하게 연구되어야 할 대상임을 시사한다.
