A study has been performed to provide the basic information about the current dietary habits, health related behaviors, and body indices and to bring forward the importance of this information to the people's attention based upon the relation between employee's life patterns and health conditions in their daily lives. Three hundred and five department store workers were examined from August 2006 to September 2006. With the average BMI values $23.9{\pm}2.2$ for males and $20.0{\pm}1.9$ for females, both gender groups were in normal, but 62.2% of the males were overweight and 15.4% of the females were under-weight. Regarding dietary and health related factors on how they perceive themselves, as normal were 204 (66.9%) the most and bad and very bad were respectively 43 (14.1%) and 5 (1.6%). Half of the subjects (43.2%) perceived sleeping hours to be insufficient, and 64.4% of them need to exercise regularly. As problems related to eating habits, they reported irregular meal times, overeating, preference of hot and spicy food, skipping meal, unbalanced meals. Regarding weight control they have attempted were the most (73.0%), after weight reduction, 51.2% of the subjects had side effects, such as gastrointestinal troubles, anemia, dizziness, sense of fatigue, constipation, physiological disorder, and diarrhea, etc. In the food habit score, it was shown that overall average score of the subjects was $62.63{\pm}9.86$ which is lower than other studies. Female ($62.76{\pm}10.15$) had better score than male ($61.67{\pm}8.06$). While the item with the highest point was eat all three meals of the day, that was the lowest point, exercise every day. The food habit score of the younger group had lower than older group, and also they preferred sweet foods to other group. The results suggest that nutrition education for workers at specific working fields needs to be more focused on the improvement of dietary habits and health status of workers.

Objectives: Fatigue is a common symptom experienced by many people who visit Oriental medical clinics or hospital. However, there has been little study about the fatigue in the Oriental medical academic world. For this reason, we attempted to investigate the present status of fatigue of outpatients, and its relation with Health Practice Index(HPI). Methods: The subjects were 63 outpatients who visited the Tonification Clinic in Kyunghee Oriental Medical Center between January 1, 2001 and July 31, 2001. Their chief complaint was fatigue and they did not have any physical or mental problem. They were given a questionnaire which included questions reflecting general characteristics, fatigue degree and health habits. We measured degree of fatigue by Chalder scale et al. Health habits were investigated about 5 articles out of 'Breslow 7 Health habits'. Results: Among the subjects, 48 people(76.2%) were considered as 'fatigue patients' by the Chalder scale. Of this 48 fatigue patients, 27 people(56.3%) had manifested fatigue for more than 6 months. The average of scale II for all the patients was 14.05, which indicates moderate degree of fatigue. They complained fatigue, drowsiness and general weakness, dryness and discomfort of the eyes, headache, shoulder pain and neck stiffness, dizziness, heat in the upper part of the body, and poor concentration. There were no differences in degree of fatigue according to Health habits including exercise or not, smoking or not, the frequency of drinking, hours of sleeping, and body mass index. Conclusions: Many people complain fatigue symptom. Therefore doctors should have more interest in fatigue and care. This study can provide standards of prognosis of fatigue patients. Also prospective studies are needed to find relationship between health habits and fatigue degree.

Objectives : This study is a random-controlled post-design for confirmation of headache degree, quality of life, and satisfaction to therapeutical effect on chronic headache adults after management of non-medicinal treatment (acupuncture therapy and stellate ganglion block therapy). Methods : 51 clinical experiment participants were gathered and through a questioutaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified in to two groups, acupuncture group (AT group, n=28) and stellate ganglion block group (SGB group, n=23). Treatment was applied 2 times a weeks for 4 weeks. The effects of both groups were analyzed using VAS scores, BPI (Brief Pain Inventory) and the satisfaction degree to the therapy. Results : 1. The recognized score of the headache of AT group and SGB group was reduced indicating the degree of the headache was released. 2. The recognition at damage to the quality of life was reduced post therapy of AT group and SGB group, in which general activity, mood, enjoyment of life, personal relationship, and sleeping showed significant improvement of life quality, 3. The satisfaction degree to the therapy showed lower score than expectation to it in AT group and SGB group, however, it was not significant. Conclusions : The results showed that the four-week non-medicinal treatment (AT and SGB) in chronic headache patients was effective for reducing headache and releasing its damage in daily life, however, no difference in superiority was found. Therefore, non-medicinal treatment (AT therapy and SGB) could be utilized in chronic headache patients.

Objective: This study aimed to investigate the differences in temporary threshold shift (TTS) and recovery patterns according to different types of sound and volume. Methods: TTS and recovery patterns were assessed for eight students after 30-minute exposure to both 70.0 dB and 90.0 dB of factory noise (noise) as well as music. TTS was measured before exposure and two minutes post exposure, and recovery patterns were evaluated every 10 minutes for one hour. The subjects performed activities of daily life and sleeping times as usual but taking drugs or drinking alcohol were prohibited. The experiment was repeated three times with an interval of at least 16 hours. ANOVA and T-test were carried out using SPSS 19.0 for Windows. Results: The hearing threshold of all subjects before exposure was less than 30 dB at all frequencies. Mean TTSs of 70 dB noise and 90 dB noise exposure were 0.14 and 4.48 dB (p<0.001). Meanwhile, the difference in music was insignificant (-0.63 dB and 0.55 dB, p=0.063). A significance in the difference was also found between the mean TTS of music and noise exposure, more obviously at 90.0 dB (p<0.001) than at 70 dB (p=0.232). The TTS differences were found frequency-wise in terms of sound type. Mean TTS by frequency was higher at 4,000 and 6,000 Hz than at other frequencies, and higher in noise than music at the same sound pressure. The TTS difference in each frequency between both sound types was significant at 90 dB (p<0.001). Subjects mostly recovered from TTS in one hour after exposure, but not with 90 dB-noise exposure. Conclusion: TTS and recovery patterns were different depending on the sound type. When exposed to factory noise, TTS was greater and recovery time was longer compared to music at the same sound pressure. These results suggested that the difference in cognitive processes and psychological factors according to the type of sound causes a change in TTS and recovery.

The purpose of this study was to research sociodemographic characteristic, work-concerned characteristic, health behavior, life stress, psychosocial stress, job stress and self-esteem of dental hygienists and to find their effects on cortisol level in saliva. The target of this study is 219 dental hygienists registered in Daegu and Gyeongbuk Dental Hygienists Association as of February 2010. For life stress, there was significant difference depending on working years of current job(p<0.05), self health status and regular meal(p<0.01). For psychosocial stress, there was significant difference depending on age(p<0.05), daily working hours(p<0.01), self health status, sleeping hours, regular meal and hobby and leisure activity(p<0.01). For job stress, there was significant difference depending on academic background (p<0.05), job experience, position, man power appropriateness in department and working years of current job(p<0.05). For cortisol level in saliva, extra working days(p<0.05) and self health status(p<0.05) showed significant difference and job stress and cortisol level in saliva showed the negative correlation(p<0.01). Health behavior gave a significant effect to life stress by path coefficient -36.807(p<0.05) and that to psychosocial stress by path coefficient -5.209(p<0.001). And health behavior also gave a significant effect to self-esteem by path coefficient 0.561(p<0.05). Life stress gave a significant effect to psychosocial stress by 0.012(p<0.05) with self-esteem to psychosocial stress by -2.437(p<0.001) and psychosocial stress to job stress by 0.523(p<0.001). Job stress gave a significant effect to cortisol level in saliva by -0.060 (p<0.05). It was found that the most significant factor that affects cortisol level in saliva was job stress, but showed negative correlation. It can be assumed that chromic job stress cause shortage in cortisol excretion, and caused lower cortisol level in saliva.

Two hundred and fifty teachers of special school (for the disabled) and 414 elementary school teachers were selected for the targets in order to compare their degrees of fatigue symptoms and to find what kind of ralationship is between subjective symptoms of fatigue and pH is the saliva. It was 30 minutes before their closing hours on April 21th, 1989 that their physical, mental and neuro-sensory symptoms and salivary pH were examined. The test results are summarized as fallows : It is observed that an interrelation between subjective fatigue and pH in their saliva shows a significant relationship between physical and neuro-sensory symptoms in a sense of statistics. The rate of subjective fatigue complained by the special teachers is higher than that by the elementary teachers. In the case of salivary pH, the special teachers' is as a whole lower than the elementary teachers'. The complain rates in each item, checked, of special teachers are generally higher than those of the elementary teachers. It is in the mental symptom related item that there are many sub-items which show significant difference. According to the average of salivary pH based on the degrees of complained symptoms shown in the pH related items, the salivary pH of the group with complained symptoms is lower than that of the group without complained symptoms. In the rate of complaints, by sex, both sexes of the special teachers show high ones, but salivary pH is low. The complain rate of mental symptoms shown by female group from the special teacher Is significantly higher(p<0.05). By age, the group in their thirties from the special teachers show the higher complain rate of mental symptoms (29.3%) and the lower salivary pH (p<0.05) than that (15.1%) of the elementary teachers belonging to the same age catagory. However, the special teachers in their forties show the lower complain rate of physical symptoms that of the elementary teachers (p<0.05). From the viewpoint of their working years, the special teachers below 14 years and elementary teachers above 15 years in their career show high complain rates. Among those who belong to the catagory of 10-14 working years, the special teachers show the higher complain rate of mental symptoms than that of their counterparts. In the case of the salivary pH, the special teachers of all working-year catagories show the higher pH than that of the elementary teachers. But there is not significantly difference. From the viewpoint of sleeping hours in the previous night of the questionaire surveyed, among those who slept for over 7 hours, the special teachers show the higher complain rate of mental symptoms with a significant difference, but the lower salivary pH than that of their counterparts. From the viewpoint of their marital status, existence of disease history, the special teachers show the higher complain rate of subjective fatigue, but the lower salivary pH than that of the elementary teachers respectively. According to the above results, the special teachers generally show the higher complain rate of subjective fatigue, the lower salivary pH, and the higher complain rate of mental symptoms. To prevent the possible accumulation of mental fatigue of the special teachers, ways and means to make use of leisure time, recreational facilities are necessarily provided. Since the degree of fatigue and salivary pH have a correlation to some extent, it is necessary that further continuous studies on the correlation between the degrees of fatigue and salivary pH should be pursued.
