The purpose of this study is estimate the effects of treatment program as it stands for drug abusers in prison. For this study, 46 drug-related prisoner were surveyed in January, 2008 at Jinju prison which has provided special treatments for drug-related offenders. This study shows that the present treatment systems or programs don't work effectively than expected. Prisoner feel present programs won't be very helpfully after release. And they feel correction officers don't have enough concern about prisoners or treatment to them. The result also emphasizes that family members or friends' support and belief is essential to prevent recidivism and to decrease such a possibility. According to this survey result, special concern to youth abuser is necessary. And it can give more effectiveness when authorities provide more medical or physical treatments than just based on routine lecturing. Furthermore, small group treatments would be more successful comparing with large member group based program. Drug abusers want more experience study or work study programs. Finally authority's, family's, friends's and colleague's interest or concern toward prisoners could contribute to raise up the possibility of rehabilitation.

Osteoporosis is a major health problem in countries with aging populations, resulting in excess morbidity and mortality. This study was conducted to investigate knowledge and practices about osteoporosis in adults and to identify some factors which were influenced to that. 56-item questionnaire was developed including five domains(general characteristics, osteoporosis-related characteristics, knowledge of risk factors, knowledge of prevetion and practices). Subjects of this study were 368 adult ranged from 30 to 59. Data were collected during the period from June 15 to July 10, 1998 by means of a structured questionnare. The data were analyzed using descriptive statistics, t-test, ANOVA, Post Hoc, Pearson Correlation by SPSSWIN program. The results were as follows: 1. The mean knowledge score of risk factors for osteoporosis was 7.46(full score=15) and that of prevention of osteoporosis was 8,79(full score=12). 2. The mean practice score of osteoporosis was slightly higher than median value. 3. Women had better knowledge about osteoporosis risk factors and practiced more osteoporosis-prevention measures than men. Although the data demonstrated fairly good general knowledge about osteoporosis in the subjects, the older group(age 50-59), those at the highest risk of developing the disease, knew less about osteoporosis than the younger group(age 30-39) did. 4. The persons who had heard about osteoporosis and bone mineral density though mass media medical pratitioners and who didn't take any medicine for osteoporosis had better knowledge about osteoporosis and preventive measures. The practice score was significantly higer in the postmenopausal women and persons who were already diagnosed as osteoporosis patients, or who underwent bone mineral density measurements. 5. The relation between knowledge and practice was significant. In conclusion, there was a modest degree of general knowledge about osteoporosis and its consequences in adults. Further randomized studies are needed to evaluate the relationship between osteoporosis and risk factors. However, these results support the importance of education to prevent osteoporosis.

Discrimination of Parkinson's disease (PD) from Essential tremor (ET) is often misdiagnosed in clinical practice. Since tremor is time-varying signal, and dominant and harmonic frequencies are shown in tremor only with moderate or severe symptom, there are some limitations to use frequency related features. Moreover, patients with PD or ET can suffer from both resting tremor and postural tremor. In this study, 28 patients with PD and 17 patients with ET were enrolled. Tremor was measured with accelerations on the more affected hand during resting and postural conditions. The ratio of root mean square (RMS) of resting tremor to RMS of postural tremor, the mean coefficients of autocorrelation function (ACF), and the mean of differences of two adjacent coefficients of ACF at resting and postural were calculated and compared between PD and ET. The performance showed 98% accuracy with support vector machine and leave-one-out cross validation. In addition, the method accurately differentiated the patients with tremor-dominant PD from patients with ET, with 100% accuracy. Therefore, the developed algorithm can assist clinicians in diagnosing and categorizing patients with tremor, especially, patients with mild symptom or the early stage of a disease, for proper treatment.

Intervertebral disc(IVD) mainly consists of Annulus fibrosus(AF) and Nucleus pulposus(NP), playing a role of distributing a mechanical load on vertebral body. IVD tissue engineering has been developed the methods to achieve anatomic morphology and restoration of biological function. The goal of present study is to identify the possibilities for creating a substitute of IVD the morphology and biological functions are the same as undamaged complete IVD. To fabricate the AF and NP combine biphasic IVD tissue, AF tissue scaffolds have been printed by 3D bio-printing system with natural biomaterials and NP tissues have been prepared by scaffold-free culture system. We evaluated whether the combined structure of 3D printed AF scaffold and scaffold-free NP tissue construct could support the architecture and cell functions as IVD tissue. 3D printed AF scaffolds were printed with 60 degree angle stripe patterned lamella structure(the inner-diameter is 5mm, outer-diameter is 10 mm and height is 3 mm). In the cytotoxicity test, the 3D printed AF scaffold showed good cell compatibility. The results of histological and immunohistochemical staining also showed the newly synthesized collagens and glycosaminoglycans, which are specific makers of AF tissue. And scaffold-free NP tissue actively synthesized glycosaminoglycans and type 2 collagen, which are the major components of NP tissue. When we combined two engineered tissues to realize the IVD, combined biphasic tissues showed a good integration between the two tissues. In conclusion, this study describes the fabrication of Engineered biphasic IVD tissue by using enable techniques of tissue engineering. This fabricated biphasic tissue would be used as a model system for the study of the native IVD tissue. In the future, it may have the potential to replace the damaged IVD in the future.

Purpose: This study examined the effect on postural control during the stimulation of haptic touch with fingertip on the stable surface at quiet standing posture, squat flexion stage, 60 degrees squat stage and squat extension stage. Methods: The postural sway was measured on the force platform, while 30 subjects were squatting, under three different haptic touch conditions (No Touch [NT], Light Touch [LT], Heavy Touch [HT]), above the touch pad in front of their body midline. Three different haptic touch conditions were divided into 1) NT condition; squatting as right index fingers held above the touch pad, 2) LT condition (<1N); squatting as the touch pad was in contact with right index fingers pulp with a pressure not exceeding 1N and 3) HT condition; squatting as subjects were allowed to use the touch pad for mechanical support by transmitting onto it with as much force, choosing with their index fingers. Results: There was significant decrease in LT, rather than that of NT (p<0.01), and in HT, rather than that of LT (p<0.01), as the results of the distance and velocity of center of pressure (COP) in mediolateral direction at quiet standing position. In anteroposterior direction, the distance and velocity of COP in LT and HT showed significant decrease, when compared to that of the data of NT (p<0.01). There was no significant difference between the 3 conditions (NT, LT, and HT), with respect to the distance and velocity of COP in mediolateral direction, during dynamic balance (squat flexion stage, squat extension stage) (p>0.05). In anteroposterior direction, the results of the distance and velocity of COP in HT showed significant decrease when compared to that of the data of NT (p<0.05). Conclusion: Light touch, during the task, decreased the postural sway at static balance. The results suggest that haptic touch should be applied, appropriately, because it varies the effects according to different conditions.

PURPOSE: This study aimed to investigate the effect of empowerment on job satisfaction for physical therapists in general hospitals. METHODS: A total of 297 physical therapists working in general hospitals throughout the country participated in the study survey using self-administered questionnaires. The questionnaires comprised three major parts, i.e., questions about general characteristics, empowerment, and job satisfaction, which were rated using a 5-point Likert scale. Statistical analysis was performed to analyze the frequency and percentage of participants, and the independent t-test and analysis of variance were performed to determine the difference in job satisfaction according to the general characteristics. Stepwise multiple regression was used to evaluate the factors that affect job satisfaction. RESULTS: The average of total empowerment, including two subordinate concepts, was 3.29 points, that of psychological empowerment was 3.53 points, and that of structural empowerment was 3.05 points. The average job satisfaction of the participants was 3.43 points, and it showed a significant difference in age, overall work experience, current work experience, position, annual salary, and daily work hours. Moreover, job satisfaction increased as the subordinate factors for empowerment, i.e., support, resources, chance, and competence, increased. Other factors that affect job satisfaction were daily work hours, number of colleagues, type of work, annual salary, and therapeutic assistance. CONCLUSION: This study demonstrated that job satisfaction of physical therapists working in general hospitals was related to empowerment, thereby indicating that job satisfaction and work performance can be increased by improving their empowerment.

Students enrolled in Department of Radiologic Science were surveyed on satisfaction of clinical practice. Purpose of the survey was to cultivate field-oriented talents capable of changing medical environment. Total 302 students in three-year and four-year school system were surveyed withSPSS/PC+ Win 13 version. Firstly, frequency analysis was used for distribution of general characteristics and clinical practice characteristics. Secondly, one-way analysis of variance was used to identify difference in the level of satisfaction based on variables. Thirdly, simple product-moment co-relation was used to analyze relations between variables. Among other variables, which include support to clinical practice class, instructors' expertise, practice subjects, practice environment, practice time, evaluation after practice and overall practice, students were most satisfied with overall practice, which was followed by practice subjects and time. This indicates high co-relation between factors affecting satisfaction of clinical practice education.

Purpose: Sternal fractures after blunt thoracic trauma can cause significant pain and disability. They are relatively uncommon as a result of direct trauma to the sternum and open reduction is reserved for those with debilitating pain and fracture displacement. We reviewed consecutive 11 cases of open reduction and fixation of sternum and tried to find standard approach to the traumatic sternal fractures with severe displacement. Methods: From December 2008 to August 2010, the medical records of 11 patients who underwent surgical reduction and fixation of sternum for sternal fractures with severe displacement were reviewed. We investigated patients' characteristics, chest trauma, associated other injuries, type of open reduction and fixation, combined operations, preoerative ventilator support and postoperative complications. Results: The mean patient age was 59.3years (range, 41~79). The group comprised 6 male and 5 female subjects. Among 11 patients who underwent open reduction and fixation for sternal fracture with severe displacement, 6 cases had isolated sternal fractures and the other 5 patients had associated other injuries. Sternal fractures were caused by car accidents (9/11, 81.8%), falling down (1/11, 9.1%) and direct blunt trauma to the sternum (1/11, 9.1%), respectively. 3 of the 7 patients (42.9%) who underwent sternal plating with longitudinal plates showed loosening of fixation. Otherwise, none of the 4 patients who underwent surgical fixation using T-shaped plate had stable alignment of the fracture. Conclusion: Sternal fractures with severe displacement need to be repaired to prevent chronic pain, instability of the anterior chest wall, deformity of the sternum, and even kyphosis. In the present study, a T-shaped plate with a compression-tension mechanism constitutes the treatment of choice for displaced sternal fractures.

PCR detection of intestinal protozoa is often restrained by a poor DNA recovery or by inhibitors present in feces. The need for an extraction protocol that can overcome these obstacles is therefore clear. $QIAamp^{(R)}$ DNA Stool Mini Kit (Qiagen) was evaluated for its ability to recover DNA from oocysts/cysts directly from feces. Twenty-five Giardia-positive, 15 Cryptosporidium-positive, 15 Entamoeba histolytica-positive, and 45 protozoa-free samples were processed as control by microscopy and immunoassay tests. DNA extracts were amplified using 3 sets of published primers. Following the manufacturer's protocol, the kit showed sensitivity and specificity of 100% towards Giardia and Entamoeba. However, for Cryptosporidium, the sensitivity and specificity were 60% (9/15) and 100%, respectively. A series of optimization experiments involving various steps of the kit's protocol were conducted using Cryptosporidium-positive samples. The best DNA recoveries were gained by raising the lysis temperature to the boiling point for 10 min and the incubation time of the InhibitEX tablet to 5 min. Also, using a pre-cooled ethanol for nucleic acid precipitation and small elution volume ($50-100{\mu}l$) were valuable. The sensitivity of the amended protocol to Cryptosporidium was raised to 100%. Cryptosporidium DNA was successfully amplified by either the first or the second primer set. When applied on parasite-free feces spiked with variable oocysts/cysts counts, ${\approx}2$ oocysts/cysts were theoretically enough for detection by PCR. To conclude, the Qiagen kit with the amended protocol was proved to be suitable for protozoan DNA extraction directly from feces and support PCR diagnosis.
