As a variety of industrial technology advances with various materials developed, cosmetics industry in general is witnessing many kinds of new cosmetic products. At the same time, Cosmetics Act becomes effective, and cosmetics ingredient labeling is implemented. Concerns with life pattern such as life management, biorhythm, right posture, and stress symptoms are on the increase in order to seek high-quality life as well. These life patterns are closely connected not only with life quality and health but with skin management, and thus this paper conducts a survey on the connection between functional cosmetics awareness and life pattern. Results show that out of 16 questions concerning cosmetics awareness, responses to question number 3, 5, 6 and 11 have relevant differences among colleges. Furthermore, the results of cross analysis with life pattern show that there are relevant differences between the year of responses and stress symptoms and between the year of responses and right posture. Lastly, it is shown that answers to questions regarding gender and biorhythm, gender and right posture, and gender and stress symptoms are relevantly different. Further research is needed to reveal the differences between college students and ordinary people at large.

Purpose : The purpose of the present study was to access the prevalence of orthostatic dysregulation(OD) and the frequency of each category for major and minor criteria among elementary school students using the OD questionnaire. Methods : We carried out inquiry by questionnaire as to the frequency of OD among two elementary schools with 725 students, 10 to 12 years of age, residing in Gwangju, Korea. The questionnaire was made according to criteria proposed by the Japan OD Study Group. Results : Of the 725 students(male 390; female 335) questioned, the OD was found in 338 students (53.5 percent). Prevalence of OD in males(59.2 percent) was significantly higher than in females(46.8 percent)(P<0.05). Palpitation with slight exercise(95.9 percent) was the most frequent major symptom. Headaches(85.8 percent) were the most frequent minor symptom among cases of OD. Conclusion : The prevalence of OD in elementary school students in this study(53.5 percent) was higher than in other studies. Contrary to studies from other countries, the male to female ratio was reversed. Because the diagnostic criteria seem to be dependent on subjective reporting of the symptoms, a newer diagnostic system based on more objective findings should be established.

Background : The objective of this study was to understand sleep-related problems, and to determine whether the sleep questionnaires is a clinically useful method in patients who need polysomnography. Methods : Subjects were patients who performed polysomnography and who asked to answer a sleep questionnaires at the Sleep Disorders Clinic of St. Paul's Hospital, Catholic University of Korea. Baseline characteristics, past medical illness, behaviors during sleep-wake cycle, snoring, sleep-disordered breathing and symptoms of daytime sleepiness were analyzed to compare with data of polysomnography. Results : The study population included 1081 patients(849 men, 232 female), and their mean age was $44.2{\pm}12.8years$. Among these patients, 38.9% had an apnea-hypopnea index(AHI)<5, 27.9% had $5{\leq}AHI<20$, 13.2% had $20{\leq}AHI<40$, and 20.0% had $40{\leq}AHI$. The main problems for visiting our clinic were snoring(91.7%), sleep apnea(74.5%), excessive daytime sleepiness(8.0%), insomnia(4.3%), bruxism(1.1%) and attention deficit(0.5%). The mean value of frequency of interruptions of sleep was 1.6 and the most common reason was urination(46.3%). Epworth Sleepiness Scale(ESS) had a weak correlation with AHI(r=0.209, p<0.01). When we performed analysis of sleep questionnaires, there were significant differences in the mean values of AHI according to the severity of symptoms including snoring, daytime sleepiness, taking a nap and arousal state after wake(p<0.05). Conclusion : On the basis of statistical analysis of sleep questionnaires, the severity of subjective symptoms such as ESS, snoring, daytime sleepiness and arousal state after wake correlated with the AHI significantly. Therefore the sleep questionnaires can be useful instruments for prediction of the severity of sleep disorder, especially sleep-disordered breathing.

In the manufacturing industries using HDI(hexamethylene diisocyanate) product hardeners, exposure to HDI is common to spray painters in terms of inhalation and dermal or ocular contact. Due to a lack of information for spray painters in automobile and furniture industries, a questionnaire survey was conducted for the prevalence of adverse health symptoms(33 spray painters and an unexposed group n = 91) to assess the importance of personal controls. Despite the small sample size, common health symptoms were reported, such as skin symptoms(dry cracked skin-61% and dermatitis/skin irritation-33%) and respiratory symptoms(phlegm-49%, asthma-21%). In addition, other adverse health symptoms were reported, such as skin rash(12%), cough(39%), shortness of breath with wheezing(30%), chest tightness and difficulty in breathing(30%). No significant eye symptoms were reported. It was founded that the adverse health symptoms reported in this study were related to poor personal work practices and inappropriate PPE use. Therefore, appropriate personal controls like PPE use, work practices, regular training and education are suggested to minimize the risk of health symptoms. In addition, medical examination will also be suggested for individual health effects.

Purpose: The purpose of this study is to evaluate correlation between convergence insufficiency and concentration by evaluating attentiveness in children who have convergence insufficiency symptoms. Methods: The CISS survey and examination for the near point of convergence were conducted to 74 in children aged 12 to 13 years in order to divide them into a normal binocular vision (NBV) and a convergence insufficiency (CI) group. The attentiveness examination was used to all subjects to figure out their emotional problems, hyperactivity and impulsiveness problems, and managerial or functional problems with a 5-point scale. Correlation between convergence insufficiency-related symptoms included in CISS and attentiveness problems was analyzed. Results: there were 29 children (39.2%) in the CI group, the mean scores of CISS of the NBV and CI group were $5.91{\pm}3.69$ and $18.31{\pm}7.00$ each (p<0.001). On the survey of CISS symptoms, children in the CI group frequently expressed such symptoms as eye fatigue, loss of attentiveness, blurry vision, and forgetting the line they have been reading. In the attentiveness examination, the CI group ($74.83{\pm}9.83$) gained higher scores in problematic concentration than the NBV group ($46.80{\pm}11.30$). Convergence insufficiency had significantly positive correlation with total attentiveness (r=0.798). Conclusions: In elementary school students, it has been found that when perceived symptoms related with convergence insufficiency are more serious, problematic attentiveness gets serious, too.
