This study was conducted to find out basic information on better customer satisfaction and service by examining and analyzing in what routes patients mostly have selected their dental medical organizations and how they have reacted to their dissatisfaction. The subject of study included the patients who have come to dental clinics and dental hospitals to be treated in Cheonan City, Chungnam and the researcher of this study used a survey and analyzed its gathered data using an SPSS(Statistical Package for the Social Science) WIN 11.5 Program. As analysis methods, frequency and percentage were calculated to figure out the general characteristics of its subject. In addition, a ${\chi}^2$(Chi-square) test was performed to figure out the factors that patients have selected their dental medical organizations and the following results were obtained. 1. The largest number of patients selected their dental medical organizations by hearsay and more female and married patients selected them by hearsay than other patients, and there were significant differences(p<.05). 2. The dental patients put the priority on treatment techniques in their visiting hospitals and the patients who were more than 40 years old and married patients put more emphasis on treatment techniques in their visiting hospitals than other patients and there were significant differences(p<.05). 3. The said dental patients were not satisfied with the kindness of medical staffs in their visiting medical organizations; meanwhile, the patients who were aged below 30 and had an academic background of more than university degree and were unmarried were less satisfied with the kindness of medical staffs in their visiting medical organizations than other patients and there were significant differences(p<.05). 4. In terms of improvement methods or complaints, the largest number of them said that they just ignored and endured; meanwhile, the patients who were aged below 30 and had an education of more than university degree and were unmarried were more patient of improvement methods or complaints than other patients and there were significant differences(p<.05). 5. There were more patients who have introduced their visiting medical organizations to their neighboring people than the patients who have not done it; in the meantime, the patients who were aged over 40 and were married have introduced their visiting medical organizations to their neighboring people more than other patients(p<.05).

Purpose: This study was to evaluate several tasks performed at a high intensity in terms of their ability to elicit EMG activity in the serratus anterior by comparing the EMG activities of the serratus anterior, upper trapezius, and lower trapezius muscles during six tasks combined shoulder flexion with rotation. Methods: Fifteen healthy males were recruited to this study. Each subject was instructed to assume a sitting position without back support and asked to flex (90° or 120°) the right shoulder and protract the scapula in the sagittal plane with maximal external rotation; to assume a neutral position; or to internally rotate the glenohumeral joint. The EMG data were collected from the serratus anterior (SA), upper trapezius (UT), and lower trapezius (LT) muscles were normalized to maximum voluntary isometric contraction. The UT/LT and UT/SA muscle activity ratios in each task were assessed by calculating the surface EMG. Data were analyzed by two-way repeated-measures analysis of variance, with the level of significance set at p<0.05. Results: The results of this study, shoulder flexion with external rotation resulted in low upper trapezius/serratus anterior and upper trapezius/lower trapezius ratios and a relatively high level of serratus anterior activation. Conclusion: Shoulder flexion with external rotation used herein may be considered as important for clinical interventions aimed at selectively increasing SA strengthen and clinical selection of exercises for improving glenohumeral joint and scapulothoracic control.

본 논문은 $1.5{\mu}m$ n-well CMOS 공정 기술에 의해 제조된 다중 바이오텔레미트리 시스템의 동작 특성을 기술하였다. 이 시스템은 체내에 삽입된 서로 다른 센서로부터 계측한 생체 정보를 무선으로 전송하여 외부에서 수신하는 것으로 8개의 피측정체로부터 선택된 7개의 생체 신호를 연속적으로 체외로 전송 한다. FM송신기와 센서 인터페이스 회로를 제외한 체내 삽입 시스템은 $4{\times}4mm^{2}$의 크기로 집적화 하였고, 집적 화한 IC는 $3{\times}3{\times}2.5cm$의 하이브리드 패키지에 수용하였다. 이 시스템의 특징은 8개의 피측정체중에서 임의의 피측정체를 선택할 수 있을 뿐 아니라, 외부 시스템의 커맨드 신호와 선택 신호에 의해 체내 삽입된 전원의 ON/OFF가 가능하다. 이와 같은 전원의 간헐적 동작으로 커맨드 수신기 자체의 소비 전력도 줄일 수 있다. 현재 국내에서 개발되고 있는 각종센서를 이 시스템과 결합해서 삽입하면 혈압 ECG, EMG, 체온 등의 생체정보를 측정하고 분석하는데 매우 편리할 것으로 기대한다.

인간은 주변 환경 속에서 경험하는 다양한 사물이나 대상을 유사관계를 기준으로 범주화하고 평가하는 인지적인 활동을 하고 있다. 이것은 인간을 둘러싼 모든 환경적 요소를 자신에게 의미있는 개념 단위로 이해하기 위한 필수적인 수단이라고 할 수 있다. 일반적으로 SD법(Semantic Differential Method)으로 대표되는 종래의 감성평가방법에서는 계측대상을 '집단적인' 경향으로 간주하여 독립적으로 평가판단을 하도록 요구하여 왔다. 그러나 이와 같은 SD법만으로는 인간의 유연한 유사성 판단능력을 평가에 반영하기에는 불충분하다. 이에 본 논문에서는 자극의 직감적 범주화와 각 범주 내에서의 대표-비대표사례의 유사성 판단을 기초로 한 계층적인 감성평가방법을 제안하였다. 제안한 평가방법의 유효성 검증을 위하여 감성적 소구력이 높은 장신구의 스캔화상을 실험자극으로 선정하여 감성평가실험을 실시하였다. 실험결과 직감적 범주화 작업, 대표사례의 선출, 대표사례의 평가득점을 비대표사례의 초기값으로 설정한 계층적인 감성평가방법은 종래의 SD법을보완할 수 있는 감성평가방법으로서의 근거가 마련되었다.

Purpose: This study was to determine the effects of abdominal breathing training using biofeedback on stress, immune response, and quality of life. Method: The study design was a nonequivalent control group pretest-posttest, quasi-experimental design. Twenty-five breast cancer patients who had completed adjuvant chemotherapy were enrolled. The experimental group(n=12) was provided with abdominal breathing training using biofeedback once a week for 4 weeks. State anxiety, cancer physical symptoms, serum cortisol, T cell subsets(T3, T4, T8), NK cell and quality of life were measured both before and after the intervention. Result: Though state anxiety, cancer physical symptoms, and serum cortisol were reduced after 4 weeks of abdominal breathing training using biofeedback, there was no statistical significance. It showed, however, improvement in quality of life (p=.02), and T3(p=.04). Conclusion: Abdominal breathing training using biofeedback improves quality of life in breast cancer patients after a mastectomy. However, the mechanism of this beneficial effect and stress response requires further investigation with special consideration in subject selection and frequency of measurement. Nurses should consider this strategy as a standard nursing intervention for people living with cancer.

Purpose : The purpose of this study was to systematically review the studies on the effects of social story intervention on the individuals with autism spectrum disorders(ASD) to provide the basis for evidence-based practice. Methods : In order to find out the studies on the effect of social story intervention on individuals with ASD, studies published from 2011 to December 2020 were searched on Google Academic Search. The keywords used were "autism spectrum disorder AND social story". A total of 16,900 studies were searched, and from these, 12 studies were selected based on the application of the selection and exclusion criteria. The included studies comprised of 10 single subject design studies and 2 randomized controlled trials design studies. The included studies were analyzed in accordance to population, intervention, outcome measures and results. Results : As a result of analysing the subjects of the included studies, we found out that pre-school children and adolescents were the most common groups of individuals diagnozsed with ASD. In addition to ASD, the diagnosis of the subjects included intellectual disability, Asperger, and Prader-willi. We found out that there were more interventions that were mixed with other interventions, than just the pure social story interventions. In particular, video modeling was found to be the most frequent intervention. This was followed by photo-based social stories. For outcome measure, autism social skills profile was found to be the most often used standardized assessment. For a non-standardized assessment, social desired behavior was found to be the most frequently evaluated behavior, followed by personal problem behavior. Of all the dependent variables, the dependent variable reported as "effective" was the most, followed by "some effective". Conclusion : This study is organized to help the individuals with ASD, families, researchers, and therapists understand the effects of social story intervention on the individuals with ASD in an easy fashion. Further, therapists can use this study as the basic data for evidence-based practice.
