BACKGROUND/OBJECTIVES: The study was performed to investigate health-related lifestyle, dietary habits, and depression according to exercise frequency to understand complex factors that affect effective health management. Thus, exercise frequency, health-related lifestyle, dietary habits, and depression were evaluated in college students in Seoul and Gyeonggi-do areas. SUBJECTS/METHODS: A survey was conducted on college students, aged 19-29, in Seoul and Gyeonggi-do areas from May 13 to May 31, 2020. A total of 594 questionnaires were collected and 566 (269 from males, 297 from females) were statistically analyzed, except 28 with incomplete responses. Collected data were analyzed using SPSS WIN 21.0 program. RESULTS: The sex distribution of the 3 groups according to exercise frequency was significantly different; the ratio of males in over 3 times/week group was significantly higher than those in 1-2 times/week group and no-exercise group (P < 0.001). The height (P < 0.001), weight (P < 0.001), and body mass index (P < 0.05) were significantly higher in over 3 times/week group compared to no-exercise group. The ratio of subjects who answered 'good' or 'very good' for subjective health condition was significantly high in the order of 'over 3 times/week' group (59.1%), '1-2 times/week' group (34.5%), and 'no-exercise' group (25.0%) (P < 0.001). The ratio for meal regularity was high as 56.6% in 'over 3 times/week' group and the ratio for irregular meals was significantly higher in 'no-exercise' group (67.2%) and '1-2 times/week' group (54.9%) (P < 0.001). Among questions on dietary habits, 'Eat meat, fish, egg or beans' (P < 0.01) and 'Eat fruit' (P < 0.01) were significantly higher in 'over 3 times/week' group compared to 'no-exercise' group. 'Drink more than 2 liters of water' (P < 0.001) was 0.70 in 'over 3 times/week' group, which was significantly higher than 0.54 in '1-2 times/week' group and 0.38 in 'no-exercise' group. Moderate depression and severe depression that need treatments were significantly lower in 'over 3 times/week' group (18.7%) compared to '1-2 times/week' group (26.0%) and 'no-exercise' group (29.7%) (P < 0.05). CONCLUSIONS: It is considered that combined intervention for exercise habits, proper dietary habits, and depression management is needed for effective health management.

This study is a descriptive survey to explore the health lifestyle of adults. The study subjects are teachers of elementary. middle and high school. and staffs of research institutes located in Chungchung Province and Daejon city. The data was collected from Jan. to march 1997 through self reporte for structured questionnaire. Fantastic check list of Wilson and Ciliska for Health Lifestyle Assessment and DSM-III-R for somatic symptom were used as tools. Data was analysed by frequency, $X^2_test$, t-test and Anova using SAS program. The results are as follows: 1. There were statistically significant differences In drinking(t=7.75, P=.000), exercise(t=-2.99, P=.003)and interpersonal relationship(t=2.22, P=.027) among 10 health lifestyle between smoking group and non-smoking group, in drinking(t=17.98, P=.000), exercise(-4.71. P=.000), and job satisfaction(t=2.22, P=.027) between drinking group and non-drinking group, and in eating habit(t=-2.00, P=.045), drinking (t=4.47, P=000), exercise (t= -16.49, P=000), keeping traffic law(t= -2.68, P=.007), personality (t= -2.05, P=.040) and anxiety/depression(t=-3.47, P=.000) between exercise group and non-exercise group. 2. There was statistically significant difference in cardiovascular symptom(F=4.22, P=.0l) among somatic symptoms of subjects according to exercise level. 3. There was statistically significance difference in lifestyle according to smoking level(F=, 3.33, P=.011), drinking level(F=9.17, P=.0001) and exercise level(F=11.93, P=.000l), and in somatic symptom according to sex(t=-3.93, P=.0001), weight(F=3.83, P=.022), exercise level (F=3.29, P=.03) among general characteristics. 4. There was statistically significant difference between sex in general (t= -3.64, P=.0001), gastrointestinal(t=-2.21, P=.02), musculoskeletal(t=-3.92, P=.001), and total symptom (t= -3.92, P=.0001). 5. There was statistically very highly signigicant difference In weight according to smoking($x^2=25.18,\; P=.001)$ and exercise$(x^2=16.46,\; P=001)$. 6. There was statistically significant difference in frequency between smoking group, drinking group and exercise group$(x^2=24.52,\;P=.001)$. Among a number of habit, smoking, drinking and exercise are important factors of human health to prevent related disease morbidity and death. It is essential for industrial health nurse to committ in this subject considering the influence of those factors and lifestyle on health. There is also a relationship of weight with smoking and exercise, the frequency of overweight/obesiy in smoking/ no-exercise group were high. It is quite necessary for the people having cardiovascular symptom to exercise to lower morbidity and mortality. The industrial health nurse has to keep In mind on this point and consider of time and facilities of fitness of employee. It needs to explore the cause by further research on somatic symptom of women. This research shows that concerning the relationship between smoking, drinking, and exercise, health care provider must take not only management of disease, but health behaviors and lifestyle into consideration.

Object: To analyze the effect of a media-campaign for "walking exercise participation improvement", which impacted walking-related awareness and behavior change of residents in Seoul. Method: This study used three campaign media including printing information, walking exercise indication board and a public advertisement of cable TV to lead a walking-related awareness change and practice frequency(number of days per week walking) and time(minutes per day walking) of walking exercise. To evaluate the exposure and message-recall levels of a campaign and effects of awareness change and walking practice, this study used a questionnaire survey(N=377). Result: 1) Group of exposure to campaign more participate and had the higher frequency(p=.015) and time(p=.023) in walking exercise and in comparison with group of nonexposure. 2) Group of changed awareness to campaign more participate and had the higher frequency and time in walking exercise and in comparison with group of no changed perception(p <.05). 3) Level of message recall of ${\ulcorner}$printing information${\lrcorner}$ was associated with number of days per week walking, and level of message recall of ${\ulcorner}$public advertisement of cable TV${\lrcorner}$ was associated with minutes per day walking at a statistically significant level(p <.05). Conclusion: These results suggest that media campaign can enhance the success of community-based efforts to promote awareness change and walking practice.

The objective of this study was to make comparison of the physical work capacities(PWCs) for three different types of tasks. For this purpose, an ergometer exercise, a treadmill exercise, and lifting activities with four different frequencies (2, 5, 8, 11 lifts/min) for the lifting range from floor to 76cm were considered. Oxygen consumption rates and heart rates were measured during the exercises and lifting activities. The PWC values for ergometer exercise test was 2562.71 ml-O$_{2}$/min and the one for treadmill exercise was 2874.89 ml-0$_{2}$/min. The value of lifting PWC increased from 1774.07ml-0$_{2}$/min to 2296.76 ml-0$_{2}$/min as the lifting frequency increased from 2 to 11 lifts/min. The ratio of the lifting PWCs to the ergometer PWCs increased from 69.36% to 89.77% as the lifting frequency increased. To the treadmill PWCs, the ratio increased from 62.21% to 85.24% as the lifting frequency increased. From this result, it is appears that the PWCs based on the lifting tasks rather than PWCs by ergometer or treadmill exercise should be considered to determine the physiological criterion for safe weights for lifting tasks. Therefore, the physiological criteria of the NIOSH Guideline should be reexamined.

Muscle fatigue is characterized as a progressive increase in discomfort arising from the active muscle at moderate load levels are maintained. The median frequency is the most commonly used as a parameter to describe muscle fatigue. However, the estimate of the median frequency is difficult to indicate muscle fatigue because of its high standard deviation and instability. This paper investigates the power changes of the appropriate low frequency band as a fatigue parameter in EMG during isotonic exercise. To select the appropriate band, linear regression lines are employed to calculate the slopes and the coefficient of determination. Three females and seven males volunteered to participate in surface EMG recordings placed on the biceps brachii and each recording experiment continued until their exhaustion. The results of experiment shows that the power changes of the selected low frequency band (15~45 Hz) have linear slopes and high determinant coefficients. Therefore, this fatiguing parameter using the power changes of the low frequency band is valid to measure the state of muscular fatigue.
