Purpose: This study aimed to investigate the prevalence of musculoskeletal symptoms (MSSs) and their correlation with subjective health condition (SHC) among emergency medical technicians (EMTs). Methods: A self-reported questionnaire was disseminated to EMTs (N=257) at emergency medical institutions and fire stations. Results: The prevalence of MSSs was very high in the studied EMTs: 88.3% reported having MSSs. The most commonly affected site was the lower back (73.9%) followed by the neck (56.8%) and the shoulder (55.6%). MSSs were more common in women than in men, and its frequency increased with age. MSSs in the neck and shoulder were more increased in EMTs with < 1 year of service. MSSs in the hand / wrist / finger or leg / foot were significantly increased in EMTs of emergency medical institutions than those of fire stations. Job satisfaction was significantly lower in those with MSSs of the lower back. The subjective heath condition was decreased with age, marriage, or smoking. There was significant corelation between MSSs and SHC. Conclusion: This study suggests that MSSs are a reasonably common problem for EMTs, and that solutions need to be imposed such as some actual tasks or items related to work postures, work control, and work organization.

This study was intended to describe the hypertensive patient`s lifestyle and quality of life by creating a hypothetic model on the lifestyle and quality of life and by examining a causeand effect relationship, and to contribute to countermeasures for practicing their lifestyle and improving the quality of life through creating a predictable model. Exogenous variable(ξ) of hypothetic model in this study composed of a family support, hypertension knowledge, perceived benefit and toughness. Endogenous variable(η) composed of self-esteem, perceived health state, depression, lifestyle and quality of life. There were 6 measured variables for exogenous variable(x). There were 9 measured variables(y) for endogenous variable. Also, there was error variable (δ, ε) of an individual. The survey was conducted for 207 hypertensive parents who received an out-patient service for 3 weeks from September 15, 2003 to October 3, 2003 after diagnosing as hypertension from 2 general hospitals in Daegu. As the conformance of hypothetic model in this study, there were χ2=155.81, standard χ2(χ2/df)=2.32, GFI=0.903, NFI=0.971, CFI=0.982, and RMSEA=0.080. Generally, the hypothetic model and actual data were well coincided. The higher the hypertension knowledge was(t=6.030), the higher the perceived benefit was(t=9.429), the higher the toughness was(t=2.783), and the higher the perceived health state was(t=2.282), the higher the lifestyle was. However, the degree of depression (t=-0.038), family support(t=1.161), and self-esteem(t=0.518) was not affected. The higher the family support was(t=10.476), the higher the self-esteem was(t=7.244), the higher the perceived health state was(t=6.996), the lower the degree of depression was(t=-2.044), and the higher the practice degree of lifestyle was(t=3.315), the higher the quality of life was. However, the toughness(t=1.672) didn`t have a significant influence on the quality of life. It was modified to increase the model conformance and gain a conscious model As the result of model revision, for the model conformance, there were χ2=118.43, standard χ2=1.69, GFI=0.923, NFI=0.976, CFI=0.982, and RMSEA=0.078. As the revised model showed the better conformance than hypothetic model, it seemed to be more suitable model. In the revised model, the perceived benefit(t=9.440) affected the lifestyle in the revised model. Then, the lifestyle was influenced by hypertension knowledge(t=6.139), toughness(t=2.757), family support(t=2.078), perceived health state(t=1.962) in the order. As a factor which affected the quality of life, there were the family support(t=10.461), self-esteem(t=7.368), perceived health state(t=6.989), lifestyle(t=3.316), toughness(t=2.584), and depression(t=-1.968) in the order. It showed the significant effect.

This study was performed to reveal the correlation between the general characteristics and the related perception and the degree of management on hair, scalp and hair loss with the adult male. The subjects were 212 cases and the survey was conducted from November 2008 to December. As for general characteristics, the conditions of scalp and hair are not good as those of higher educated levels, more than 4000,000 won earnings a month, worse health conditions and more severe stress. On the factors of general characteristics affected the perception of scalp, hair and hair loss, the degree of the perception is the highest in the educated level of graduated school(3.21point), the bad conditions of scalp and hair(2.95, 2.93point). On the other hand, those with no dandruff(2.79point), no hair loss(2.81point) and proper thick hair(2.59point) have higher perception of scalp and hair compared with those with. On the factors of general characteristics affected the management of scalp, hair and hair loss, the average(2.17 points) means adult male don't take good care of the management. The management of scalp, hair and losing hair showed the high point in proportion to the educated levels and the earning. As a result, we found that some general characteristics of adult male affected condition, perception and management of scalp, hair and hair loss. So we need to understand the severe situations of the related problems of hair for adult male, and try to be established the public and educational policy to improve the quality of life in adult male.

이종렬(Jong-Ryol Lee),김동훈(Dong Hun Kim),이상민(Sang-Min Lee) 한국콘텐츠학회 2021 한국콘텐츠학회논문지 Vol.21 No.4

스티렌은 플라스틱과 같은 생활용품에 광범위하게 사용되며, 건강에 위해를 야기시킬 수 있다. 스티렌이 간 조직 중 항산화계 효소 활성에 미치는 영향을 확인하기 위해 50 mg/kg, 200 mg/kg 및 400 mg/kg 용량을 4일 동안 1일 2회 복강 투여하였다. 혈청 ALT 및 AST 활성 변동은 대조군에 비해 400 mg/kg 투여군에서 각각 약 1.2배 (p<0.05) 및 약 43.3% (p<0.05) 유의하게 증가하였다. 이는 투여용량이 증가할수록 간손상이 심화되었다는 것을 의미한다. MDA 함량 변동은 대조군에 비해 400 mg/kg 투여군에서 약 37.1% (p<0.05) 증가하였고, XO 활성도는 200 mg/kg 투여군에 비해 400 mg/kg 투여군에서 약 15.2% 증가하였고, CYPdAH 활성도는 약 40.4% (p<0.05) 유의하게 증가하였다. 생성된 과잉의 활성산소종을 제거하기 위한 항산화계 효소인 GPx, CAT, SOD 및 GST 활성도는 대조군에 비해 400 mg/kg 투여군에서 각각 약 33.0%(p<0.05), 약 41.2% (p<0.05), 약 47.2% (p<0.05) 및 약 27.6% (p<0.05) 유의하게 감소하였다. GSH 함량은 200 mg/kg 투여군에 비해 400 mg/kg 투여군에서 34.5% (p<0.05) 유의하게 감소하였고, 소모된 GSH 함량은 스티렌과 스티렌 중간대사산물에 의한 것으로 생각된다. 이상의 결과로 보아 스티렌의 대사과정에서 생성된 과잉의 활성산소종과 독성 중간대사산물에 의해 간 손상이 유발되었고, 이는 해독에 관여하는 항산화 효소계와 불균형과 관련이 있을 것으로 생각된다. Styrene is a commercially important chemical used mainly in the production of raw materials and plastics. To determine the effect of styrene on hepatic activities of antioxidant enzymes, styrene was treated to Sprague-Dawley rats at 50 mg/kg, 200 mg/kg and 400 mg/kg (i.p) twice a day for 4 days. There were determined the significantly increased activities of serum AST (aspartate aminotransferase), ALT (alanine aminotransferse), and the increased content of MDA (malondialdehyde) at the dose of 400 mg/kg compared to the control. The hepatic activities of XO (xanthine oxidase) and CYPdAH (cytochrome P450 dependant aniline oxidase) in the dose of 400 mg/kg compared to the dose of 200 mg/kg were more increased, which means the excessive ROS (reactive oxygen species)s were produced during Phase I. In addition, significantly decreased were rates of the hepatic activities of GPx (glutathione peroxidase), CAT (catalase), SOD (superoxide dismutase) and GST (glutathione S-transferase) at the dose of 400 mg/kg compared to the control. And, the group at the dose of 400 mg/kg showed more significantly decreased GSH (glutathione) level than the group at the dose of 200 mg/kg. The decrease in GSH could ascribe to the toxic metabolites of styrene, such as styrene oxide. In conclusion, these results indicate that the excessive ROSs and the toxic metabolites of styrene may result in the hepatotoxicity, and be related to their imbalanced activities for antioxidant enzymes.

The purpose of this study was to observe the effects of aroma treatment on some stress related hormones to obtain the basic data for prevention of stress-related disease. On November 18, 2006, 37 healthy soldiers for the subject of investigation were divided into 4 groups. The four groups included aroma inhalation, aroma massage, regular oil massage and the control group that did not have any treatment. The effect of each treatment on the blood levels of ACTH and cortisol and blood pressure, pulse rate was observed. The results of this study: 1. At 40 minutes after the test, all the test groups except the control showed a tendency to elevate in blood pressure, especially the aroma massage group was higher in systolic (p<0.05) or diastolic blood pressure (p<0.01). And in the massage group, the systolic pressure was higher than the control (p<0.05). 2. After 20 or 40 minutes, all the groups except the control showed significantly decreased blood levels of ACTH (p<0.01). Furthermore, the aroma inhalation group showed the highest decreasing levels of ACTH among all groups (p<0.001). 3. Cortisol was significantly reduced in the all test groups but the control group (p<0.01) 20 minutes after the test. Cortisol continuously decreased in the aroma inhalation group (p<0.01) and massage group (p<0.05) 40 minutes after the test. The highest decrease of cortisol in the blood was shown in the aroma inhalation group. These results suggested that aroma inhalation and physical treatment such as massage might reduce the initial stress. To improve health science and alternative medical treatment, aroma inhalation is considered to be the meaningful method of treatment.

This study was performed to reveal the relations between the diffuse hair loss and the mental (emotional) states by investigating the degrees of stress, self-confidence and depression. The subjects were 212 cases and the survey was conducted from November 2008 to December. As for the general characteristics with the diffuse hair loss, the public office worker in the occupation and more 4,000,000 won earned group in the salary showed the highest occurred rates of the diffuse hair loss. The stressful feeling (2.32 points/2.10 points) and the depressed feeling (1.57 points/1.37 points) were significantly higher in diffuse hair loss group compared with control, and the self-confidence (2.97 points/3.10 points) were significantly lower in diffuse hair loss group compared with control, As for the diffuse hair loss group, the initiate of the symptom was 3-5 years before and the cause was the genetics, which were the most common responses. In addition, the level of stress by the depilation was higher in innate case (2.39 points) than in acquired case (2.21 points), and the degree of caring about the depilation was significantly high in the response of very cared (2.39 points, 3.37 points) on the stress and the on self-confidence that meaned the levels of stress and self-confidence were influenced by the depilation. The level of the depressed was the significantly highest in over 6 years-depilation group. In conclusion, the depilation, itself, can badly influence the (mental) emotional states such stress, self-confidence and depression, so we need to look into the various solutions to solve not only physical depilation, but also the mental difficulty caused by the depilation for the better welling-being.
