  • 뇌파 및 심전도 생체신호를 복합적으로 이용한 감정인식을 통한 실시간 사용자 인터페이스를 제안한다. 기존에 뇌파를 통한 감정인식의 문제점이었던 낮은 정확도를 개선하기 위해 뇌파의 Theta, Alpha, Beta, Gamma의 상대파워 값과 심전도의 자율신경계 비율을 혼합하는 복합 생체신호 감정 인식 시스템을 개발했다. 기쁨, 공포, 슬픔, 즐거움, 화남, 혐오에 해당하는 6가지 감정을 인식하기 위해 사용자별 확률 값을 저장하는 데이터 맵을 생성하고, 채널에 대응하는 감정 인식의 정확도를 향상시키기 위해 가중치를 갱신하는 알고리즘을 제안한다. 또한 뇌파로 구성된 단일 데이터와 뇌파/심전도 생체신호 복합 데이터의 실험 결과를 비교한 결과 23.77%의 정확도 증가를 보였다. 제안된 인터페이스 시스템은 높은 정확도를 통해 게임 및 스마트 공간의 제어에 필요한 인터페이스로 기기에 활용이 가능할 것이다.

  • Objectives In this study, the Sasang Constitutional diagnosis were carried out to Vietnamese subject living in Vietnam, and the external applicability of Sasang Constitutional Medicine was evaluated by analyzing the physiological symptoms and the pathological symptoms according to their constitutions. Methods Total 170 Vietnamese subjects who live in Hanoi were invited from Sep. 2012 to Jun. 2013 for the research, and subjects were diagnosed by 2 Sasang Constitution Medicine specialists. The collected data were analyzed in terms of the physiological symptoms and the pathological symptoms according to the Sasang Constitutions. Results There were significantly different in the physiological symptoms according to Sasang Constitutions, which were 'digest', 'perspiration', 'excrement', 'hot and cold', 'water' and in the pathological symptoms, which were 'sting pain in head' in Soyangin, 'back pain' in Soeumin, 'chest discomfort' in Taeeumin, 'skin discomfort' in Taeeumin, 'fatigue in the afternoon' in Soyangin, 'digestion' in Soeumin. Conclusions The Sasang Constitution Medicine which is a Korean traditional medicine is also applicable to foreign countries, and it can contribute to the health promotion.

퇴원환자의 신체적 기능상태 및 미충족 간호요구도: 만성호흡기질환, 장루보유 대장암, 뇌졸중 환자를 중심으로 (Physiological Functional Status and the Levels of Unmet Care Needs after Discharge in Patients with Chronic Pulmonary Disease, Colorectal Cancer, and Strokes)

  • Purpose: The purpose of this study was to identify physiological functional status and unmet care needs among patients with chronic pulmonary disease, colorectal cancer, and strokes after discharge. Methods: A crosssectional study was conducted with 224 patients diagnosed with aforementioned diseases from January to July in 2014 in two different tertiary hospitals in Seoul and its suburban area. Physiological functional status and unmet care needs were collected using Karnofsky Performance Status (KPS) Scale and Problems After Discharge Questionnaire-English version(PADQ-E) respectively. Data were analyzed using SPSS/WIN 21.0 program. Results: Patients with chronic pulmonary disease and colorectal cancer showed a low level of physiological functional status (mean: 77.20 and 77.60 out of 100 respectively) and a high level of unmet care needs (mean 2.23 and 2.63 out of 4 respectively). Stroke patients showed a high level of unmet care needs in the category of 'counseling', 'physical complaints', and 'instructions'. Physiological functional status was significantly associated with unmet care needs in all three patient groups and it showed a significant effect on unmet care needs in patients with stroke. Conclusion: The results showed that patients after discharge were still having insufficient functional status and various unmet care needs. The results of this study suggest a development of nursing care service for patients with chronic diseases after discharge.

  • Objectives:This study was designed to investigate the characteristics of personality changes and emotional distress using the Personality Assessment Inventory (PAI) in patients with traumatic brain injury(TBI), divided into mild (MTBI) and severe (STBI) groups according to the severity of injury. Methods:The subjects were consisted of 25 patients with MTBI, 25 patients with STBI, and 25 normal controls. They were interviewed with the PAI. The data were analyzed by ${\chi}^2$ test, analysis of variance and Tukey test. Results:The results were the followings. First, Negative Impression in validity scales was elevated above cutoff point(T score 70) in both MTBI and STBI groups. Second, the clinical scales of which scores elevated above the cutoff point were Somatic Complaints, Anxiety, Anxiety-Related Disorders, Depression, and Schizophrenia in the MTBI, and Somatic Complaints and Depression in the STBI. Third, the clinical subscales above the cutoff point were Conversion, Somatization, Health Concerns, Affective Anxiety, Physiological Anxiety, Traumatic Stress, Cognitive Depression, Affective Depression, Physiological Depression, Thought Disorder, and Affective Instability in the MTBI, and Health Concerns, Cognitive Depression, Affective Depression, and Physiological Depression in the STBI. Fourth, Suicide Ideation in treatment scales was the only scale above the cutoff point in the MTBI and the others of the treatment and interpersonal scales in the MTBI and all of these scales of the STBI were not elevated above the cutoff point. Fifth, the scales of which scores showed significant difference between the MTBI and the STBI were Somatic Complaints, Anxiety, Depression, and Suicide Ideation, the subscales were Conversion, Somatization, Health Concerns, Affective Anxiety, Physiological Anxiety, Physiological Depression, and Psychotic Experiences. Conclusion:These results suggest that the patients with MTBI had more somatic and anxiety symptoms, depressed mood, and suicidal ideation than the patients with STBI. These characteristics are generally consistent with clinical observation and findings from previous studies of the patients with TBI, and the PAI seems to be a beneficial adjunctive assessment tool for the evaluation of patients with traumatic brain injury.
