Frozen shoulder is known as a self-limited disease. But, its long duration and pain nature can make the patients debilitative. And most patients cannot tolerate a chronically painful extremity and are concerned about the possibility of developing permanent dysfunction. In painful phase of frozen shoulder, some aggressive mordalties as like trigger point injection or suprascapular nerve block can beneficial to: reduce discomfort and pain. In order to document clinical results, we evaluated the results of 134 frozen shoulders treated with trigger point injection and/or suprascapular nerve block at Kyungpook National University Hospital, from January 1995 to April 1997. The treatment group was divided into 3 modalities: 17 cases in trigger point injection(TPI), 39 cases in suprascapular nerve block(SSB), and 78 cases in both methods. The supportive treatment including oral medication, heat and stretching exercise was also applied. The average age at the time of diagnosis was 57 years old and average follow-up time was 18 months. The results were as follows: Average time of significant improvement in pain was 9 days. Eighty-eight percent (119 cases) was improved in pain and range of motion after injecllion treatments; 82%(14/17) with TPI, 85%(33/39) with SSB, and 92%(72/78) with both. Early improvement of paih within 1 week was 72% in the treatment-responsive group, in which TPI group has 100% response(14/14) and sse has 94% response(31/33)

This study was conducted to investigate the relationship between knowledge of nutrition labeling and the effect on eating habits with 300 high school boys in Seoul. The subjects were divided into an underweight (UW) group (BMI < $18.5kg/m^2$, n = 42), a normal weight (NW) group ($18.5kg/m^2\;{\leq}\;BMI\;<\;23kg/m^2$, n = 129) and an overweight (OW) group (BMI ${\geq}\;23kg/m^2$, n = 79) based on their body mass index (BMI). The average age of participants was 17.8 years old and their mean height and weight were 174.9 cm and 66.5 kg. The mean BMI of subjects was $21.7kg/m^2$ which fell within the normal range. Seventy six point four percent of subjects perceived nutrition labeling and they acquired the information pertaining to it through TV and internet. The UW group and the OW group obtained it from their parents, relatives and friends, while NW group acquired it from school. There were significant differences among groups in the acquired source of the information on nutrition labeling (p < 0.05). The NW group and the OW group trusted nutrition labeling more than the UW group, but there were no significant differences among them. Forty five point five percent of the UW group and 40.7% the NW group were satisfied with nutrition labeling education, while only 15.8% of the OW group did it. The OW group checked nutrition labeling more than the UW group and the NW group at the point of food purchase. The primary reason for examining nutrition labeling was 'to check nutrient contents' in the UW group and the NW group, while the OW group examined it to improve health including regulation of body weight. There were significant differences among groups with regards to the reason for examining nutrition labeling (p < 0.001). The OW group was aware that nutrition labeling affected their eating ha-bits significantly more than the other groups (p < 0.05). Therefore, application-centered education on nutrition labeling and the strong support of the government is needed in order to improve nutrition labeling use and to apply the information from nutrition labeling into student dietary life.

Purpose: The purposes of this study were to identify Korean primary school students' knowledge of menstruation, their emotional reaction to menarche, the attitude toward menstruation and coping behaviors. Method: A cross-sectional survey design was employed in this study. The subjects were 200 female students who were recruited from 5th and 6th grade in five primary schools in J city, Korea. Data was collected by a structured questionnaire. Result: About forty-four percent of the subjects had experiences with menarche. The mean age of menarche was 12.4. The mean score of the students' knowledge of menstruation was 2.26 on a seven point scale. The mean scores of the emotional reaction to menarche and the attitude toward menstruation were 3.20 and 3.74 on a five point scale, respectively. Knowledge of menstruation was significantly related with a positive emotional reaction to menarche and a positive attitude toward menstruation. Also, there were significant differences in the knowledge of menstruation, the emotional reaction to menarche and attitude of menstruation among female students with positive coping behaviors and those without positive coping behaviors. Conclusion: Beyond the simple transference of knowledge, girls need to also be given mental and emotional support in order to minimize emotional and socio-psychological problems caused by early menarche.

The first reported the neural blockade of ganglion impar for pain control of perineal pain in 1990 by Plancarte and his fellows. they used 6ml of 10 percent phenol. but the point of issues, same as other neurolytics, are that it is impossible to check and control its spreading, so it might be possible to destruct the coccygeal plexus and sacral nerve, and also it has only short action time. Because of these problems, it could be very dangerous to attempt this procedure especially not for relieving the pain on cancer terminal patient, but for the sympathectomy of ganglion impar on the other purpose. We used the RF generator which had the control ability to point out the destructive lesion accurately. inserted We made the small burr hole on the sacrum near the sacrococcygeal junction directly, through the hole, and performed thermocoagulation to the ganglion impar.

In order to investigate the effect of the height of application point of lateral loads and reinforcing steel bars in walls and columns in improving the seismic behavior of confined concrete block masonry walls, an experimental research program is conducted. A total of twelve one-half scale specimens are tested under repeated lateral loads. Specimens are tested to failure with increasing maximum lateral drifts while a vertical axial load was applied and maintained constant. The specimens adopted are two-dimensional (2D) hollow concrete block masonry walls with different parameters such as shear span ratio, inflection point and percent of reinforcement in confining columns and walls. Test results obtained for each specimen include cracking patterns, load-deflection curve, and strains in reinforcement and walls in critical locations. Analysis of test data showed that above parameters generate a considerable effect on the seismic performance of confined concrete block masonry walls.

Purpose: This study was designed to examine the validity of the evidence-based guideline on pain developed by Registered Nurses Association of Ontario(RNAO) translated into Korean based on the experts' opinions. Methods: The panel consisted of experts of 60 registered nurses in surgical units, medical doctors and nursing managers who were experts in pain assessment and management. The validity of translated RNAO guideline was evaluated in terms of appropriateness, applicability, and utilization in current practice. Appropriateness and applicability of each recommendation were measured with 9 point scale, whereas utilization was measured by yes/no question. Data were analyzed by mean, standard deviation, and percent. The experts' opinions were analyzed by content analysis method. Results: In general, most of the recommendations in the guideline received above 7 point in appropriateness and applicability. However, above 20% of recommendations showed less than 50% of utilization rates in current practice. Conclusion: The reasons for low utilization of recommendations in current practice are in need for investigation. This study can be used for the development of guideline more acceptable in Korean health care settings and improve the quality of care for the abdominal surgery patients suffering from pain in Korea.

This study is concerned with the analysis of cutting force system acting on ball-nose end mill in three-dimensional surface machining process. Conical tipped circular cutting edge element model and free surface machining process types are proposed to apply oblique cutting theory, and then derived equations are used for numerical approach of cutting force curves by matrix method. This approach has a good agreement with experimental results both in magnitude and shape within the range of 15 percent, which was conformed on 6061-T6 aluminum workpiece having twofold curvatured surface. From the cutting load variation to edge location, it is confirmed that circular cutting edge shapes has a better cutting ability than that of straight and both have a singularity near a tool point. It is also verified that what kind of machining condition is recommendable for three-dimensional machining process in connection with deflection of the cutter to workpiece and tool point wearing or system stability.
