생체에서 발생되는 생체신호는 신호의 발생원에 따라서, 신호의 물리적 특성에 따라서, 또는 이를 측정하는 센서의 특성에 따라서 분류할 수 있으며, 그 중에서도 임상적 진료를 위한 의료의 범위를 포함하여 다른 분야에도 광범위하게 활용될 수 있는 생체 신호는 전기적인 형태로 측정되는 생체 전기 신호라고 할 수 있다. 여기에서는 생체에서 측정되는 전기적인 신호가 어떻게 활용되고 또 활용될 수 있는지 그 응용 범위에 대하여 살펴보고자 한다.(중략)

Using a reliable assessment procedure and according to the severity of hyperactivity, thirty-six clinic-referred outpatients, 6-12 years of age, were given a diagnosis of Attention Deficit Disorder with Hyperactivity(ADD+H) or without Hyperactivity(ADD-H). Comparisons of behavioral measurement by Conners Rating Scale(CRS) and Home/School Situations Questionnaire(HSQ/SSQ) revealed that the children with ADD+H displayed more pervasive behavior problems at home and school than the children with ADD-H. Also the children with ADD+H were more likely to be delinquent and aggressive compared to the children with ADD-H when using the Child Behavior Check-list(CBCL) for parents Hyperactivity symptom in ADHD is highly correlated with aggression scale on CBCL These finding suggest that ADD+H and ADD-H may differ in clinical disease entity.

This single-blinded, nonequivalent control group pretest-posttest study was undertaken to evaluate the effectiveness of simulation education on clinical judgement, collaboration, communication skills, and perceived education practices and simulation design characteristics among student nurses in Korea. Participants were 47 students (19 in the experimental group and 28 in the control group) recruited by convenience sampling. The simulation based clinical reasoning education consisted of seven weekly, 120-minute high fidelity simulations. All participants completed the pretest and 7-week post measurements of a clinical judgment, collaboration, and communication skills with 4-week post measurement of collaboration, and participants in the experimental group provided a measurements of perceived education practices and simulation design characteristics. Data were analyzed using repeated measured ANOVA, and mixed linear model with SAS 9.2. Significant improvements were found in the experimental group for clinical judgment, collaboration, communication skill, and perceived education practices and simulation design characteristics. The study results show the impact of the perceived education practices and simulation design characteristics on facilitating the effectiveness of simulation education. The findings suggest a feasible and sound teaching method for student nurses and the need for further studies with a larger sample.

Clinical experiment is a set of experience to help student acquire technic, attitude and knowledge by participating in the clinical work. The radiotechnologists who are employed in departments of radiology serve as clinical instructors. Their responsibilities include teaching students them to become competent radiotechnologist. Clinical instructors often have no formal preparation in teaching student. The purpose of this study is to review some principals that will help clinical instructors support and foster the professional development of student radiotechnologists. The clinical instructor should be able to identify the qualities of instructor, the characteristics of feedback and use facillitation skills when is evaluated student performance. And the survey was performed to evaluate the satisfaction of student participated in clinical experiment, the purpose of this research is to fine the problems and improvements in clinical experiment of student radiotechnologist in Korea.

Objects : Cancer patients receiving radiotherapy have many psychological problems. Those problems depend on clinical factors of cancer and the characteristics of patients. This study was designed to estimate the morbidity of psychiatric disorder and to investigate the relationship between psychiatric disorders and clinical variables. Methods : The subjects were 47 patients who had been treated by radiotherapy. Psychiatric disorder was diagnosed according to DSM-IV. The authors assessed the relation between psychiatric disorder and demographic features, clinical features of cancer such as site, duration, frequency of recurrence of cancer, and patients' awareness of disease and expectation of outcome of radiotherapy. Results : 21 patients(44.7%) had a psychiatric disorder. The most common psychiatric disorder were adjustment disorder(66.7%), and the next major depressive disorder(23.8%). There was a significant positive relationship between psychiatric disorder and recurrence of cancer, patients' expectation of poor outcome after radiotherapy. Psychiatric morbidity was significantly low in those who had no evidence of recurrence and who considered radiation treatment as curative. However, site and duration of cancer, patients' awareness about serious illness were not related with psychiatric disorder. Conclusion : Psychiatric disorders are common among cancer patients on radiotherapy. Further clinical attention and effective treatment of psychiatric complication in cancer patients are needed not only for reducing symptoms but for better adjustment.

In Korea, there are debris-flow disasters induced by typhoon and localized torrential rainfall annually. There are particularly extensive debris-flow disasters in Gangwon-do because of its geomorphological characteristics; the extensive coverage of mountainous region, steep slope, and shallow soil. In this paper, we constructed a GIS database about topological characteristics of debris-flow basin in Gangwon-do by years of field survey. Also, we conducted frequency analysis based on this database with the digital forest type map and the digital soil map. We analyzed frequencies of debris-flow by simple count for topological characteristics, whereas we analyzed by considering an area ratio based on GIS for physiognomic and geologic characteristics. We used slope, aspect, width, depth and destruction shapes for analysis about topological characteristics of debris-flow basin. Also we used attributes of forest physiognomy, diameter, age, and density about physiognomic characteristics, and i n terms of geologic characteristics, we used attributes of drainage class, effective soil depth, subsoil properties, subsoil grave content, erosion class, parent material of soil, and topsoil properties. In consequence, we figured out topographic, forest physiognomic, and geologic characteristics of debris-flow basin. This result is applicable to establish a rational disaster prevention policy as a fundamental information.

There are two types of clinical research to figure out risk factor for disease using collected data. One is prospective study to approach the subjects from the present time and the other is retrospective study to find the risk factor using the subject's information in the past. Both approached and study design are different but the purpose of the two studies is to identify a significant difference between two groups and to find out what the variables to influence groups. Especially when comparing the two groups in clinical research, we have to look at the difference between the impact clinical variables by group while controlling the influence of the baseline characteristics variables such as age and sex. However, in the retrospective study, the difference of baseline characteristic variables can occur more frequently because the past records did not randomly assign subjects into two groups. In clinical data analysis use covariates to solve this problem. Typically, the analysis method using the analysis of covariance of variance, adjusted model, and propensity score matching method. This study is introduce the way of equality adjustment between groups data analysis using covariates in retrospective clinical studies and apply it to the recurrence of gastric cancer data.
