Glenohumeral internal and external rotation with shoulder abducted in the frontal plane often causes impingement of the supraspinatus tendon. whereas similar activity in scapular plane does not cause impingement. The Purpose of this study was to determine if assessment among the three positions as 30 degrees, 60 degrees, 90 degrees abduction in the sitting position of the scapular plane could be affected the comparison between intemal and external peak torque, total work, average power. In this study, Isokinetic shoulder rotational strength was evaluated in twenty healthy male university students, using the Cybex NORMTM System (CYBEX Division of LUMEX, Inc., Ronkonkoma, New York). Test data was gathered in the plane of the scapular, 30 degrees of horizontal flexion anterior to coronal plane, and the subjects performed the test with the arm 30, 60, and 90degrees abducted in the sitting position. also, test speed was set at deg/sec. Statistical analysis was performed using SPSS 7.5 for Windows software and mean and standard deviations were calculated. ANOVA was used to analyze the difference of the values in the three test positions. A paired t-test was used of examining the difference in the means peak torque between external and internal rotation. Not any significant difference was found among three abduction positions in scapular plane, even though there was a consistent pattern of greater strength in the abducted position of 60 degrees. Internal relation strength peak torque and total work were greater than those of external rotation in every test positions.

Objective : This study performed to evaluate that duration of acne scars effects on Qualitative Global Acne Scarring Grading System(QGASC) grade changing and treatment duration. Also this study performed to evaluate the relationship between dysmenorrhea and acne scars, and the effects of each treatment on treatment duration and Korean Acne Grading System(KAGS) and QGASC grade.Methods : 95 patients with acne scars were understood by medical records and case photos, and we evaluated pre and post acne scar grade based on KAGS and QGASC. We analyzed data by SPSS 22 for windows program, and figured out the relation between duration of acne and QGASC grade and treatment duration by Spearman correlation analysis, and performed Mann-Whitney U-test to figure out the relation between dysmenorrhea and QGASC grade. We performed Wilcoxon test to evaluate that treatment of acne scars effects on KAGS grade and QGASC grade, and performed Kruskal-Wallis test to figure out the difference of each treatment which effects on KAGS grade and QGASC grade, and performed Post-hoc analysis to figure out the group comparison.Results & Conclusions : QGASC grade depending on duration of acne was statistically significance. Subcision and Microneedle Therapy System(MTS) and pharmacopuncture were significantly improved acne scars. Other treatments were significantly more effective than subcision and pharmacopuncture combined treatment. Treatment duration of Subcision and MTS combined treatment was significantly most shortest than other treatment.

Purpose: This study was conducted to analyze occupational and leisure-time physical activity(LTPA) in male office workers and to examine factors related to LTPA. Method: The subjects for this study were 226 male office workers, from eight work places located in Seoul, who had no physical restrictions. Minnesota LPTA Questionnaire (Taylor et al., 1978) revised by Kim(1997) was used to measure LTPA and revised Tecumseh Occupational Physical Activity Questionnaire (Motoye, 1971) was used to measure occupational physical activity. The data were collected from May 4 to May 19, 2001 using a semi-structured questionnaire with interviews and self reports. The collected data were analyzed using SPSS Windows 10.0 Program. Results: The results of this study are summarized as follows. 1. The mean level of physical activity was 8,716.9kcal/wk. The occupational physical activity was at 6,605kcal/wk(75.8%) and the level of LTPA was 2,111.4kcal/wk (24.2%). 2. Using 2,000kcal/wk as a base for categorizing LTPA as active or inactive, it was found that there were 94 subjects(41.6%) in the active group. 3. Subjects in their thirties had a lower level of LTPA than subjects in other age groups (F=3.484, p<.05). Physical activity, self-efficacy (r=.405, p=.000) and perceived health status (r=.301, p=.000) were positively related to LTPA. 4. Participants in club activities had a higher level of LTPA than those who did not (t=-2.369, p=.020). Support for physical activity(r=.164, p=0.13) was positively related to LTPA. Conclusion: This study suggested that to increase physical activity in male office workers, physical activity promotion programs should be established according to age and sex especially for those who are in their thirties and for women, and should include strategies strengthening support through peer groups and family, developing club activities and increasing physical activity self-efficacy.

Objectives : We studied in order to compare the differences between the symptoms of patients and findings of MRI and X-Ray of patients with herniated disc which has been diagnosed often recently. Methods : We randomly selected among the 301 patients with X-Ray and L-spine MRI films who have visited Jaseng Hospital with low-back pain and lumbar and low extremity pain from Jan.1st of 2009 to Jan.28. We used SPSS 13.0 for Windows I in analyzing statistical data of study results and the level of significance were below 0.05. Results and Conclusions : 1. If there were radiating pain, based on MRI findings, the amount of herniation was more severe(P>0.05). 2. If the finding of a X-ray showed narrowing, based on MRI findings, the amount of herniation was more severe(P>0.05). 3. There were no significant differences between the presence of radiating pain and the findings of X-Ray(P>0.05). 4. Among the 301 cases, cases which showed findings beside HIVD were 79. 7 cases of hemanggioma(2.3%), 24 cases of spinal neoplasm(cord cyst, tumor etc)(8%), 7 cases of spondylitis(2.3%), 16 cases of spinal canal stenosis(5,3%) 9 cases of ligamentum flavum thickening(3%) and 16 cases of facet syndrome(5.3%).

The purpose of this research is to investigate the influence on mandibular movements and TMJ sounds with changes of head and neck posture. For the research, twenty patients who had complained of TMJ sounds without any other symptoms of cranio-mandibular disorders, were selected as subjects for measurements of TMJ sounds, and radiographs on transcranial view of TMJ were taken on ten of the subjects. From NHP, UHP, DHP and FHP, aspects of mandibular movement and TMJ sound were investigated from each posture. Aspects of mandibular movement and TMJ sound were observed by measuring total vibration energy(Integral), peak amplitude, maximum amound of mouth opening, and TMJ sound-emitting point using Sonopak for windows (version 1.33) and Bio-EGN(Bioresearch Inc. WI. U.S.A.). Head and neck movement-measuring instrument, CROM(perfomance attainment Inc. U.S.A.) was to maintain even head posture. Degrees of inclination of UHP and DHP were determined at 30' and distance of FHP was 4cm. The results obtained were as follows. 1. Total vibration energy and peak amplitude of TMJ sounds were decreased more on UHP and on UHP and increased more on DHP and FHP than that on NHP. 2. At the maximum mouth opening, distance of TMJ sound-emitting point were decreased more on UHP and increased more on DHP and FHP than that on NHP. 3. The amounts of the maximum mouth opening were increased more on UHP and decreased more on DHP and FHP than that on NHP. 4. For the changes of the head posture with mouth opening observed in radiograph, condylar head was positioned more lower-anteriorly on UHP, and more upper-posteriorly on DHP and FHP than that on NHP. From the results obtained as above, considering positive influence of the change of head and neck posture, avoiding down-head and forward-head posture, and recommending upper- head posture can prevent the progress of temporomandibular disorder and lead to successful treatment for the patients with temporomandibular joint sounds.

During the winter season in Korea, the relative humidity of greenhouse at night often exceeds 90% because air temperature inside the greenhouse is usually controlled using a heater with all of windows closed to minimize heat loss, thereby requiring the use of a dehumidifier that can maintain optimum humidity levels of $70{\sim}80%$ to provide a good growth condition of crops. Also, such a high humid condition can cause the development of a pest, such as insects, fungi or diseases. However, the use of most conventional dehumidifiers for low temperature dehumidification is limited because their performance is degraded due to frost accumulation on the evaporator coil. This study was carried out to develop a refrigeratory-based dehumidifier suitable for low temperature dehumidification in greenhouse cultivation. The developed dehumidifier consists of a condenser and an evaporator installed separately so that relative and absolute humidity levels can be reduced when air passed through the condenser and evaporator, respectively. The prototype dehumidifier showed a dehumidification capacity of $5{\sim}7kg/h$ when air with a temperature of $15{\sim}25^{\circ}C$ and a relative humidity of $70{\sim}95%$ came into the dehumidifier. Under the condition that either temperature or relative humidity was fixed, the amount of condensed water was proportional to the levels of both temperature and relative humidity.

The Computer-assisted Hazard Analysis and Critical Control Point(HACCP) program has been developed for a systematic implementation of HACCP principles in identifying, assessing and controlling hazards in institutional foodservics operations. The HACCP-based sanitation evaluation tool has been developed, based on the results of the computerized assisted HACCP program in 4 service sites of C contracted foodservice company, including 2 general hospitals with 650-beds, one office operation of 400 meals per day, and one factory foodservice of 1,000 meals per day. All database files and processing programs were created by using Unify Vision tool with Windows 95 of user environments. The results of this study can be summarized as follows : 1. This program consists of the pre-stage for HACCP study and the implementation stage of the HACCP system. 1) The pre-stage for HACCP study includes the selection of menu items, the development of the HACCP recipe, the construction of product flow diagrams, and printing the HACCP recipes and product flow diagrams. 2) The implementation of the HACCP system includes the identification of microbiological hazards, the determination of critical control points based on the decision tree base files. 3) The HACCP-based sanitation evaluation tool consisted of 3 dimensions of time-temperature relationship, personal hygiene, and equipment-facility sanitation. The Cronbach's alphas calculation indicated that the tool was reliable. The results showed that the focus groups rated the mean of importance in time-temperature relationship, personal hygiene, and equipment-facility sanitation as 4.57, 4.59 and 4.55 respectively. Based on the results, this HACCP-based sanitation evaluation tool was considered as an effective tool for assuring product quality. This program will assist foodservice managers to encourage a standardized approach in the HACCP study and to maintain a systematic approach for ensuring that the HACCP principles are applied correctly.

Purpose: Recently there are scientific evidences for the health effects of Asian dust-storms. Particularly in 2002, the daily average of $PM_10$ exceeded 600 and 700 $\mu{g}/m^3$ in March and April respectively. We examined the effects of Asian dust‐storms on perceived symptoms and preventive behaviors among children, adults, and elders. Method: The subjects of this study were 425 children, 444 adults and 60 elders. A questionnaire survey was carried out on the children and the adults by teachers and on the elders by interviewers to obtain information on demographic variables, perceived symptoms and preventive behaviors, previous respiratory disease, environmental tobacco smoke, and proximity between the house and the road during Asian dust-storms. We analyzed using descriptive statistics, $X^2$ test and multiple logistic regression models. After adjustment for potential confounders, we estimated the odds ratios and 95% confidence intervals of the children and the elders for perceived symptoms and preventive behaviors. Result: The elders had a significantly higher prevalence of respiratory symptoms than the other groups. The children had a significantly higher prevalence than the adults in getting URI (1.51), coughing (1.68), rhinorrhea (1.46), fever (2.39) and medication for allergy or asthma (1.90). The children had better behaviors than the elders in closing windows (3.57), taking less outdoor recreational activity (2.59) and staying home (2.60). Conclusion: This study suggested that children and elders are susceptible to the effects of Asian dust on health. Health educators should inform these populations about the influence of Asian dust and provide health education for preventive behaviors.
