A retrospective study was carried out of 125 cases of fractures or fracture-dislocations of the thoracolumbar spine. These were treated by either operative or nonoperative methods at the Kang Nam Sacred Heart Hospital of Hallym medical college during the period of Jan. 1980 to Oct. 1983. A comparison of clinical and radiographic findings regarding stability of spine, neurologic recovery, and back pain demonstrates distinct similarities and differences as follows: 1. Operative methods were found to be more efficient in correcting deformity and restoring stability than nonoperative methods. 2. No difference could be detected in degree of neurological recovery between operative and nonoperative methods in paraplegic patients. 3. Pain was more pronounced in the patients treated by nonoperative methods. 4. A classification of injuries based on radiographic findings is not satisfactory to confirm stability. There is a need for several methods of classification in order to planning the treatment program.

PURPOSE: The purposes of this study were to explore the functional status of elderly residents and to analyze time use, and finally identify factors to predict nursing care needs in relation to functional status and health related variables. METHODS: In this study a descriptive-correlational design was used. Functional status of participants was obtained through interviews, and nursing care time was examined using a 1 min time-motion study with a standardized instrument developed by Korea Long-Term Care Planning Committee (2005). RESULTS: The mean total functional score was 65 (range 28-125) and mean total nursing care time was 144.15 min per day. There were significant positive relationships between total nursing care time, marital status, back pain, dementia, and vision impairment. Multiple regression analyses showed that a liner combination of number of illnesses, types of primary disease, ADL, IADL, cognitive function, nursing demand, and rehabilitation demand explained 42.8% of variance of total nursing time. ADL (beta=-.533) was the most significant predictor of nursing service need. CONCLUSION: Identifying factors that result in variations of service need has implications for adequate nursing service, estimation of optimum nurse to patient ratio, quality of care and patient safety.

Patients with cerebrovascular accidents often have abnormal electrocardiograms in the absence of known organic heart disease. In 1901 harvey Cushing has discovered sinus bradycardia in CVA patients. Burch, Myers and Abildskov were the first to report electrocardiographic abnormalities in CVA. Since then many reports have appeared in the literature. This study was done utilizing brain C-T scan to varify and localize the site of CVA, for purposes of correlation of the CVA with abnormalities of electrocardiogram. We obtained the following results. 1. Among 250 cases of CVA, 107 cases were excluded due to pre-existing cardiac disease, abnormal serum electrolyte and early death. 2. Among 143 cases, intracranial hemorrhage were 62.9% and brain infarction were 37.1%. 3. In intracranial hemorrhage, normal electrocardiographic finding were only 4.5%. Q-Tc prolongation revealed 64.5%. 4. In brain infarction, normal electrocardiographic finding was only 5.7%. Q-Tc prologation revealed 64%.

BACKGROUND: The pathological significance of adolescent obesity is increasing, as research results indicate that about 80 percent of obese teenager becomes obese as adults. However, most studies on obesity have been mainly centered on the biomolecular aspect of obesity, thereby offering little solution to the clinical application and the promotion of overall health for people. This study investigates into the psychological factors of adolescent obesity, mainly that relating to stress. METHODS: After having chosen 14 third year classes from two middle schools, one from the Kang nam and the other from the Kang puk region of Seoul, I have distributed questionnaires to the total of 501 students. For calculating the degree of stress among the students, I have employed the BEPSI (Brief Encounter Psychosocial Instrument) K, transforming each 5 positive questions into 1 point, which were summed up and divided by 5 (the BEPSI K score). RESULTS: Controlling the confounding factor, the regression coefficient regarding the Body Mass Index of the BEPSI K score was 0.661, t as 3.122, and R Square as 0.05, indicating the statistical relevance of the two factors. A multiple linear regression analysis of theses data yielded the following equation: Body Mass Index=15.6+0.661 x BEPSI K score(R2=0.05) Although the R Squre, as 0.05, was relatively low, this statistical result proves that the rise in stress contributes to the increase of Body Mass Index, thereby indicating that stress functions as an important factor for adolescent obesity. CONCLUSION: For remedying and preventing adolescent obesity, one must make use of the BEPSI K examination and calculate the degree of stress among the adolescent. This study further implies that the best solution to the problems of obesity among adolescent is for the family members, the educational institutions, and the society as a whole to understand and to help the adolescent overcome frequent mental stress resulting from their daily living.

BACKGROUND AND OBJECTIVES: Electrical dyssynchronicity (Dsyn) appears to be prognostic of survival in congestive heart failure (CHF). Recent study has shown some discrepancy between the electrical Dsyn and the Doppler tissue image (DTI) assessed mechanical Dsyn. The aim of our study was to evaluate the relationship between the QRS duration and DTI assessed Dsyn. SUBJCETS AND METHODS: One hundred and forty patients, with CHF and left ventricular ejection fractions < or =40%, were enrolled. DTI was performed on 5-basal and 5-mid segments to assess the time from the R-wave to the peak systolic velocity (RS time). A QRS duration >130 msec, standard deviation (SD) of the RS time >40 msec, or a difference in the maximal and minimal RS times (RS time-diff) >100 msec were indicators of'Dsyn'. RESULTS: The prevalence of myocardial Dsyn, by QRS duration, SD of the RS time and the RS time-diff were 19, 43 and 47%, respectively. The SD of the RS time (49.8+/-23.6 vs. 36.6+/-20.7, p<0.01) and the RS time-diff (139.2+/-63.2 vs. 98.0+/-54.3, p<0.01) were prolonged in the wide (>130 msec) compared with the narrow QRS group. There was also a weak positive correlation between the QRS duration and the SD of the RS time (R=0.34, p<0.001) and the RS time-diff (R=0.38, p<0.001). However, from a cross-tabulation analysis, more than one third of patients had a discrepancy between QRS duration and DTI assessed mechanical Dsyn. From a multivariate analysis, a major determinant of the SD of the RS time was the QRS duration. CONCLUSION: Although a major determinant of the DTI assessed Dsyn was the QRS duration, more than one-third of patients had a discrepancy between electrical and mechanical Dsyn. Therefore, not only the QRS duration, but the DTI assessed Dsyn, should be measured when considering cardiac resynchronization therapy.
