목 적: 폐쇄성 수면무호흡증은 일반인구의 $2{\sim}5%$ 정도에서 발견될 정도로 흔한 질환이며, 특히 심혈관계 질환이 병발되는 경우가 많아 치료의 중요성이 점차 증가되고 있는 질환이다. 폐쇄성 수면무호흡증과 심혈관계 질환간의 관계는 명확하지 않으나 자율신경계가 매개 작용을 할 것으로 추정되고 있다. 폐쇄성 수면무호흡증에서의 교감신경계 활성도가 증가되어 있다는 연구들이 이를 뒷받침 해준다. 또한, 폐쇄성 수면무호흡증의 치료 방법인 지속적 상기도 양압술이 자율신경계를 변화시키는 것으로 알려져 있다. 그러나, 현재까지 폐쇄성 수면무호흡증 환자에서 지속적 상기도 양압술 치료 전후에 자율신경계의 변화를 측정한 연구는 많지 않으며, 결과도 일정하지 않다. 본 논문에서는 스펙트럼 분석 방법을 사용하여 폐쇄성 수면무호흡증의 환자의 심전도를 분석함으로써 지속적 상기도 양압술 전후의 자율신경계 변화를 고찰하였다. 방 법: 임상적으로 폐쇄성 수면무호흡증이 의심되어 수면 다원검사실에 의뢰된 환자들 중 병력청취, 이학적 / 신경학적검사와 야간 수면다원검사 시행결과 수면무호흡증으로 진단 된 17명을 연구대상으로 하였다. 기본 측정일과 지속적 상기도 양압술 시행일 모두 디지털 수면다원검사기로 기록을 저장하였으며, 양압술 시행일에는 무호흡 해소를 위한 처방압력을 결정하기 위한 목적으로 수면다원기록 시행 전 시간에 걸쳐 양압술을 시행하였다. 수면다원기록 판독은 국제판독기준에 따랐다. 그후 기본 측정일과 양압술 시행일 각각의 2단계 수면, 렘수면에서 잡음이 없는 300개의 연속된 심박동 기록을 선택하였다. 이를 대상으로 한 스펙트럼 분석에서 VLF(very low frequency) power, LF(low frequency) power, HF(high frequency) power, LHR(LF/HF ratio) 값을 산출하였다. 그리고, 심박동 변량(R-R variance)과 심박동 평균값도 산출하였다. 기본 측정일과 양압술 시행일 모두에서 수면다원기록과 동시에 혈중산소포화도($SaO_2$)도 측정하여 비교하였다. 제 변인의 값은 Wilcoxon signed ranks test로 통계 처리하였다. 결 과: 모든 대상군에서 양압술 시행으로 무호흡이 해소되었다. 양압술 시행일의 2단계 수면에서 기본 측정일의 2단계 수면에 비해 VLF power(p<0.05), LF power(p<0.01) 그리고 R-R variance(p<0.05)가 감소하였다. 렘수면의 LF power도 감소하였다(p<0.05). 최저 혈중산소포화도(p<0.01)와 평균 혈중산소포화도(p<0.01)의 증가도 관찰되었다. HF power, LHR, 심박동 변량 그리고 심박동 평균값의 유의한 차이는 없었다. 결 론: 본 연구에서는 처방압력 결정을 위한 양압술 시도 중에도 교감신경계 활성도가 즉각적으로 감소하는 것을 폐쇄성 수면무호흡증에서 관찰할 수 있었다. 부교감신경계의 활성도 변화는 유의하게 나타나지 않았으며, 이는 수면무호흡증에서 나타나는 혈동력학적인 변화가 교감신경계의 활성도의 증가와 관련이 있을 가능성을 시사해준다. 지속적 상기도 양압술을 처음 사용하는 날부터 폐쇄성 수면무호흡증 환자에서 즉각적이고 효율적으로 교감신경계 활성도가 감소하는 결과를 고려할 때, 임상적으로는 지속적 상기도 양얍술을 장기간 적용시 폐쇄성 수면무호흡증의 치료 뿐 만 아니라, 폐쇄성 수면무호흡증에서 병발하는 심혈관계 질환을 예방하고 치료에 도움을 줄 가능성도 시사된다.

치매는 기억력을 포함한 다양한 영역의 인지기능의 손상을 특징으로 하는 질병군으로 정의된다. 그러므로 현재 치매진단을 위하여 사용되고 있는 대부분의 진단기준들은 치매의 진단에 있어 기억 장애를 필수요소로 포함하고 있다. 기억력의 감퇴는 노화과정의 결과로서 나타날 수 있다. 치매와는 달리 노화에서의 기억력의 감퇴는 노화에 따른 정상으로 간주되며 사회적 그리고 직업적 기능의 영역에서 심각한 어려움이나 손상을 초래하지 않는다. 우울증 또한 기억장애를 동반할 수 있다. 하지만 치매와는 달리 우울증에서는 언어성 지연회상과 재인기억의 감소는 나타내지 않는다. 치매환자들에서의 기억장애도 병소의 위치에 따라 다른양상으로 나타날 수 있다. 피질성치매에서의 기억장애는 정보의 부호화와 기억강화과정의 이상에 의해 초래된 것인데, 피질하치매에서의 기억장애는 인출의 장애에 의한 것이다.

Purpose: This study was done to provide fundamental data for developing a depression prediction model by discovering main factors that affect depression in patients who do maintenance hemodialysis. Method: The subjects were 191 patients doing maintenance hemodialysis selected from outpatient dialysis clinics at 9 major general hospitals, The Instrument tools utilized in this study were adapted from depression, fatigue, sleep disturbance, stress, adaptation, symptoms, daily activities, and role limitation and thoroughly modified to verify reliability and validity. The collected data was analyzed with a SPSS-PC 11.0 Window Statistics Program for real numbers, percentage, average, standard deviation, and multiple regression. Results: The correlation factor for depression was (M=2.54) fatigue(M=3.12), sleep disturbance (M=2.82), stress(M=3.04), adaptation(M=2.53), daily activities(M=2.24), symptoms(M=2.37), and role limitation(M=2.24). The strongest factor that affected depression was explained by symptoms of the patients who performed hemodialysis. The analysis of the factors that affected depression revealed a $58.4\%$ prediction in symptoms, stress, role limitation, and adaptation. Conclusion: It has been confirmed that the regression equation model(Depression=7.351 + .266$^{\ast}$symptoms + .260$^{\ast}$stress -.l89$^{\ast}$adaptation + .057$^{\ast}$fatigue) of this research may serve as a prediction factor for depression in Hemodialysis Patients.

Objectives: The aim of this study was to retrospectively evaluate the efficacy and safety of Ongyeong-tang (OGT) in the treatment of insomnia in patients afflicted with neurological diseases, according to the medical records of one medical institution. OGT is a herbal prescription that originates from the "Synopsis of Prescriptions of the Golden Chamber" and has been used for menopausal symptoms, uterine diseases, skin diseases, insomnia, and other neuropsychiatric symptoms. Methods: Medical records of patients who visited Kyung Hee University Korean Medicine Hospital from January 1, 2021 to June 30, 2022, received outpatient or inpatient treatment, and met the inclusion criteria were used in this study. Results: Twenty-four patients satisfied the inclusion criteria and were included. The Pittsburgh Sleep Quality Index-Korean version (PSQI-K) score was used to evaluate the outcomes before and after treatment. After an average of 14.42±9.2 days of OGT extract intake, 20 patients (83.3%) experienced improvement. The remaining four (16.7%) had no change in their symptoms, but none demonstrated worsening of symptoms. The total PSQI-K score showed a statistically significant decrease from 13.08±4.54 to 10.42±4.58 (p<0.001). Sleep quality, sleep duration, sleep disturbance, use of sleeping medications, and daytime dysfunction also showed statistically significant improvements. Conclusions: Administration of OGT extract may be a relatively safe and effective therapeutic option for insomnia in patients with neurological diseases.

Hearing loss caused by exposure to industrial machine noise results in devastating disability that is mostly preventable. And recent researches indicate that the noise may also induce hypertension and cardiovascular disease. In addition the sleep polygraph provides many indicators of sleep disturbance by the noise. In this paper we make an analysis on ball bearing machine noise, a kind of the industrial noise. The analysis of Its power spectrum is based on FFT(Fast Fourier Transform). And then the spectral results of the noise are compared with that of the spectrum for an auditory signal. The signal is measured from the pronunciation of two Koreans. Finally we suggest the most important stratagem to prevent the noise for worker's health and efficiency.
