This study is to provide basic data regarding prevention of VDT syndrome by surveying the computer usage and understanding the VDT subjective symptoms. Data collection was done using a structured questionnaire among 617 students in middle and high schools in J city, Chonbuk province from 1 April 2002 to 20 April 2002. Modified and adjusted study tools were used which were based on previous studies on the actual computer usage and the VDT subjective symptoms, and the self-assessment tool for VDT syndrome by Moon et al(1991). Collected data were analyzed by SPSS program. The results were as follows: It showed 97.2% of students in middle schools and 97.6% in high schools to hold personal computer, 92.2% of middle school students and 84.7% of high school students commonly used computer at home. Communication was the obvious reason to use computer in 55.8% of middle school students and 71.6% of high school students. The mean of the VDT subjective symptoms among students in high schools showed $1.09{\pm}.69$ which higher than that of $.80{\pm}.59$ among students in middle schools (t=5.666, p=.000). Musculoskeletal symptom was marked the highest in the scoring of VDT subjective symptoms among students in middle and high schools. The higher grade, The more pocket money, The less breaks or exercise taken during computer use, The more they feel harmful about using computer, The actual time of computer longer than 3 hours per use were contributed to the higher score of the VDT subjective symptoms among students. There are suggestions following this study: To establish a systematic preventative program and management regarding the current computer use among students especially in relation to the VDT subjective symptoms. To develop better educational programs for parents regarding time-limit and to create appropriate environment in computer use.

This research is based on self-filling survey which 220 dental hygienists who work in seoul participated on July 2006 through August 2006. This survey was analyzed the experience item and occurred time of the symptoms and the time of acute and vanish of the symptoms that dental office's working environment effects on physical subjective symptom. We suggest a plan to minimizing physical subjective symptom for health manage of dental hygienist. We found out the fact that dental hygienists were unsatisfied with hospital air condition and this polluted air condition cause them physical subjective symptom in work place. As follows analyzed results ventilation time is below the 3-times a day, this may be have some trouble in indoor air quality. The experience the symptoms level is higher then non-experience level in "Fatigue and sleepiness", "Dorsalgia, omarthralgia, cervicodynia", "Hypersensitivity", "Dry eye, itch, smarting", "Headaches" and a subjective symptom is occurred at after 11:00(am) more then 60%, 50% of the dental hygienist. This experience the symptom' pain is vanished after the work and reduced when go out the office and building, respectively. The ratio of the experience the symptoms and starting time the symptoms is anywhere from 12 noon to 4 pm (73.2%) in a day. The time of acute pain the symptoms is anywhere from 12 noon to 4 pm (78.7%) refer to the individual characteristics and work environment.

Objective: This study was conducted to investigate the association between subjective distress symptoms and argon welding among workers in Gyeongnam Province shipyard. Method: 31 argon and 29 non-argon welding workers were selected as study subjects in order to measure concentrations of personal dust, welding fumes and other hazardous materials such as ZnO, Pb, Cr, FeO, MnO, Cu, Ni, $TiO_2$, MgO, NO, $NO_2$, $O_3$, $O_2$, $CO_2$, CO and Ar. An interviewer-administered questionnaire survey was also performed on the same subjects. The items queried were as follows: age, height, weight, working duration, welding time, welding rod amounts used, drinking, smoking, and rate of subjective distress symptoms including headache and other symptoms such as fever, vomiting and nausea, metal fume fever, dizziness, tingling sensations, difficulty in breathing, memory loss, sleep disorders, emotional disturbance, hearing loss, hand tremors, visual impairment, neural abnormality, allergic reaction, runny nose and stuffiness, rhinitis, and suffocation. Statistical analysis was performed using SPSS software, version 18. Data are expressed as the mean ${\pm}SD$. An ${\chi}^2$-test and a normality test using a Shapiro wilk test were performed for the above variables. Logistic regression analysis was also conducted to identify the factors that affect the total score for subjective distress symptoms. Result: An association was shown between welding type (argon or non-argon welding) and the total score for subjective distress symptoms. Among the rate of complaining of subjective distress symptoms, vomiting and nausea, difficulty breathing, and allergic reactions were all significantly higher in the argon welding group. Only the concentration of dust and welding fumes was shown to be distributed normally after natural log transformation. According to logistic regression analysis, the correlations of working duration and welding type (argon or non-argon) between the total score of subjective distress symptoms were found to be statistically significant (p=0.041, p=0.049, respectively). Conclusion: Our results suggest that argon welding could cause subjective distress symptoms in shipyard workers.

Method: The method of the research was interruptive time series design. The research objects are 25 hospital workers with myofascial pain syndrome at B hospital in Busan from July 22, 2002 to August 18, 2002. SPSS Win 10.0 was used for data analysis, paired t-test and repeated measures ANOVA for hypothesis test. Result: The recipients of meridian massage felt less pain than before(F=12.587, p=.000). The recipients of meridian massage felt less often than before (F=6.705, p=.001). The recipients of meridian massage got lower score on subjective symptoms of myofascial pain than before(F=12.857, p=.000). The recipients of meridian massage had lower blood pressure than before(systolic blood pressure; t=4.697, p=.000, diastolic blood pressure; t=3.426, p=.002). The recipients of meridian massage did not get the lower number of pulse than before(t=0.33, p=.744).

The surgical treatment of craniofacial disorders, using metallic internal osteofixation system has inspired an evolution with advanced operative technique and fixation devices over past two decades. As any other surgical procedures, this procedure also associates problems such as infection, palpability, loosening, and restrict craniofacial skeleton growth, which lead to undue secondary operations for removal. These problems are improved by using bioabsorbable osteofixation system. We compared the patient's subjective symptoms using bioaborbable system versus metallic osteofixation system in zygomatic bone fracture. we should take the individual steps (postoperative 2 weeks, and 1 year) in treating fractured zygoma. From August, 2001 to August, 2003, we used bioabsorbable osteofixation system in 28 patients in zygomatic fracture ($Biosorb^{TM}FX^{(R)}$) and compared 23 patients who were treated with metallic osteofixation system. There was no significant difference in the both groups in subjective symptoms and postoperative result.
