The purpose of this study is to provide some basic data for the direction of nursing education and practice to prevent nursing malpractice as investgating perception of the nurse on the nursing malpractice and its case. Data were collected from 450 nurse working in four general hospitals which were located in Chonbuk province from November 9 to 21, 1998 through questionnare. The structured instruments developed by the reseacher were used for collecting data. The Results were as follows: 1) As for the cognition of the nursing malpractice case, the transfusion accident was 37.3%, the side-effects of KCL injection(19.3%), hymen rupture by uterus cancer test, the side-effects of aminophyllin injections on dyspnea patient and the others were 10% below. 2) With regard to the channel of the perception of the nursing malpractice case, mass-communication was taken first and followed through by neighbors, In-service education, school education, continuing education 3) As for the direct${\cdot}$indirect experience of the nursing malpractice case, transfusion accident was 51.3%, the fall of NPO patient after an operation 40.1%, the side-effect of KCL injection 32.5%, suicide of the psychiatric patient 32.5%, and the others were 30% below. 4) The possibility of nursing malpractice case was an average 2.57(${\pm}$0.91) and the highest was the fall of the NPO patient after an operation. 5) The perception on the responsibility of the nursing malpractice in its case was indicated as a joint-fault in ten nursing malpractice instances. As compared to the real decision, nurse's perception of the responsibility in the fall of the NPO patient after an operation, the side-effect of KCL injection, the tracheal edema of the patient who had a thyroid operation, the suicide of psychiatric patient, the hymen rupture by uterus cancer test accorded real decisions. But the other cases were different from the real decisions. These cases were perceived as ones of joint fault even in cases determined as Dr's single fault cases or those in which both doctor and nurse were declared free of fault. 6) Knowledge levels of the nursing malpractice, school education and In-service education were perceived as low but anxiety levels of the malpractice were high. 7) With regard to the countmeasure of the hospital after nursing malpractice, the rate answered as "the practice settled the accident temporarily and forced the person in charge to be punished" was highest. In conclusion, the level of the cognition of the clinical nurse on nursing malpractice cases was low. As nurses' perception on the responsibility of the nursing malpractice case was compared to the real decision, there was a difference in five cases out of the ten cases.

Objective: To develop a standardized instrument to measure the level of cognition for orthodontic treatment in adults, and verify its reliability and validity for assessing perceptions of orthodontic treatment in adults. Methods: A total of 406 adults aged 19-64 years were surveyed by an internet research system. A tool was developed through the instrument development and verification stages. The data were analyzed by correlation analysis, exploratory factor analysis, confirmatory factor analysis, and Cronbach's α test. Results: The instrument consisted of 11 items covering four factors related to orthodontic treatment. Three items were related to general perception, four described the perception of the treatment for adults, two related to the treatment effects, and two related to the retention of orthodontic treatment. In the reliability test, Cronbach's α was 0.845 for the 11 items. In assessments for individual components, Cronbach's α was 0.764 for the general perception of orthodontic treatment, 0.705 for the perception of this treatment for adults, 0.707 for the effects of the treatment, and 0.701 for the retention of orthodontic treatment. Finally, a measurement instrument for the perception of orthodontic treatment in adults was designed to assess the 11 items on a four-point Likert scale. Conclusions: This study developed a standard measurement instrument for assessing the perception of orthodontic treatment in adults. The proposed instrument will enable additional studies on the influence of an adult's perception of orthodontic treatment on the decision to undergo treatment.

Purpose : There is a lack of research on this field in the Republic of Korea, especially those that have seen the effect of interaction between transcranial direct current stimulation and computerized cognitive rehabilitation therapy. This study divided 30 dementia patients into a treatment group, which received transcranial direct current stimulation and computerized cognitive rehabilitation, and a control group, which received pseudo-transcranial direct current stimulation and pseudo-computerized cognitive rehabilitation. This study evaluated the effects of these treatments on the visual perception, cognition functions, and daily activities of dementia patients. Methods : Fifteen subjects were allocated to the treatment group and the other 15 subjects were allocated to the control group. Treatments were given at intervals of five sessions per week (30 minutes per session) for six weeks (30 times in total). This study used the Neurobehavioral Cognitive Status Examination (NCSE) to examine cognitive functions, MVPT to evaluate visual perception, and FIM to test daily living activities before and after applying the treatments. Results : The results of this study showed that cognitive functions, visual perception, and daily living activities significantly (p<.05) improved after the intervention in the treatment group and the control group. The changes in cognitive functions, visual perception, and daily living activities due to the treatments were significantly different between the groups (p<.05). Conclusion : The results indicated that transcranial direct current stimulation and computerized cognitive rehabilitation therapy improved visual perception and daily living activities by increasing cognitive functions. Consequently, it was found that the simultaneous application of transcranial direct current stimulation in conjunction with a computerized cognitive rehabilitation program was an intervention method that could positively affect the visual perception, cognitive function, and daily living activities of dementia patients. Based on the results of this study, the study of arbitration protocols for demential will have to be more active.
