The purpose of this study was to identify the attitudes of nutrition majors toward hiring older workers who are over fifty-five years of age. Questionnaires were sent to 500 students who are studying food and nutrition in three colleges and three universities located in Seoul and its suburbs. Data from 490 usable responses were analyzed using the SAS package program. The study showed that although the students have a favorable perception about hiring older workers, they prefer to hire younger people under the age of 30 father than older workers(over 55 year old). Additionally, even though both the younger and older people have the same ability, they would still choose to hire younger people. Also, they think that older workers are harder to train, find it more difficult to adapt to new ways of working and are slower in their work. On the positive side, the response did show that students realize that older workers are not absent from work as frequently as younger workers and that they are more cooperative than younger workers are. The data also showed that the students who had a more positive experience with older workers also perceive those workers in a more positive way than the students who did mot have experience with older workers(p＜0.0001). Finally, students who have family members who are older workers(p＜0.01) and students who are planning to work past fifty-five years of ages show more positive attitudes toward older workers(p＜0.01). Moreover male students showed more positive attitudes toward older workers than female students did(p＜0.0001).

There are not many studies on job satisfaction among older workers living alone. This study examined the determinants of job satisfaction for older workers living alone, and the job satisfaction was analyzed by the demographic-social factors, the health-psychological factors, and labor factors regarding to sex and ages. Korean Labor and Income Panel Study(KLIPS, 18th) used in this study, and the subjects were 308 older worker living alone and over 55 years old. The determinants of job satisfaction for male respondents were happiness, organizational commitment, and duration of work. Howver, the determinants of job satisfaction for female respondents were age, happiness, organizational commitment, and levels of skill. Income, organizational commitment, employment stability, and duration of work were the determinants for 55-64 years old. Education, organizational commitment, and levels of skill were the determinants for 65-74 years old. Education and happiness were the determinants for 75 years old and over. Age, income, happiness, organizational commitment, employment stability, duration of work, and levels of skill were the determinants of job satisfaction for all respondents. Finally, this study proposed the policy and practical implications for improving of job satisfaction among older workers living alone.

After warming-up exercise for 20 minutes, Isokinetic measurement of trunk strength for flexor and extensor was done by using Cybex 6000 TEF Unit on 91 healthy male white workers from 22years old to 49 years old, and compared each other. 20 repetitions of trunk extension-flexion were done at $120^{\circ}$/sec angular velocity. After resting for 1 minutes, Four repetitions at two different angular velocities($60^{\circ}$/sec, $120^{\circ}$/sec) were done with 30 seconds of resting interval between each angular velocity. The purpose of this study is to obtain the isokinetic normative strength values for trunk extensors and flexors, and is to know the correlation between age, height, weight of subjects and data from isokinetic trunk strength measurement, and is to provide a guideline for exercise program of male white collar workers The collected data were analyzed by ANOVA, Duncan's Multiple Range Test, and Pearson correlation coefficiency in PC-SAS program. The results obtained were as follow; 1. There is significant positive-correlation with the statistic value between weight and peak torque of trunk muscles at two different angular velocities($60^{\circ}$/sec, $120^{\circ}$/sec)(p<01), between height and peak torque of trunk muscles at two different angular velocities($60^{\circ}$/sec, $120^{\circ}$/sec) except peak torque of trunk flexor at $60^{\circ}$/sec(p<01). 2. There is nagitive-correlation between age and peak torque of trunk muscles at two different angular velocities($60^{\circ}$/sec, $120^{\circ}$/sec), there is significant differences with statistic value between age and peak torque of trunk extensor at $120^{\circ}$/sec(p<.01). 3. Mean peak torque and mean peak torque % by body weight of trunk extensor is 1.1 times higher values than trunk flexor at $60^{\circ}$/sec. 4. There is the increase in peak torque angle of trunk flexor with increasing of age, and the decrease in peak torque angle of trunk flexor with increasing of age at two different angular velocities($60^{\circ}$/sec, $120^{\circ}$/sec). there is significant differences with statistic value in peak torque angle of trunk flexor at $120^{\circ}$/sec(p<.01). 5. There is significant decrease in endurance ratio of trunk extensor with increasing of age at $120^{\circ}$/sec(p<.01). In conclusion, peak torque of trunk extensor is 1.1 times higher values than trunk flexor in healthy male white collar workers.

This study was carried out to evaluate the relations among workers' general characteristics, work-related behaviors and health related behaviors in a steel industry with 1,134 workers in Pohang. The results were as follows; 1. The mean age of workers was 50 years old and working duration was 15 years and over. Most of them were married(94.5%) and had studied beyond high school (53.0%). They performed three shift work and most of them(63.0%) had experienced industial accidents. The frequency of noise and dust exposure was defined by a minimum of 6 hours per day, and workers complained about noise exposure(62.9%) and dust(55.6%). There were current smokers(67.7%), current drinkers(74.3%) and current exercising workers(32.3%) in the industry. The number of cigarette consumption in current drinkers was significantly high $(13.6{\pm}8.4\;pieces/day)$ and the alcohol consumption in current smokers was significantly high$(104.5{\pm}113.5\;g/wk)$. And the number of cigarette consumption of exercisers was significantly low and the alcohol consumption of exercisers was higher than non-exercisers. 3. The ratio of current smokers on frequent noise in exposed workers versus non-exposed workers was not significantly high but the current drinkers in frequent noise and dust exposed workers was significantly higher than non-exposed. 4. The normal levels of SGOT workers in non-smokers were significantly higher than in current smokers, and the normal levels of LFT (SGOT, SGPT, $\gamma-GTP$ workers in nondrinkers were significantly high. The normal levels of SBP and DBP workers in current smokers were not significantly high but were significantly high in non-drinkers. 5. The ratio of current smokers in voters unsatisfied with their job and working condition was higher than non-smokers, but the ratio of current drinkers in workers satisfied with their job and working condition were higher. 6. The significant factors for SGOT and $\gamma-GTP$ were age, the drinking amount and BMI. But the only significant factor for r-GTP was BMI. The significant factors for DBP were age, the alcohol consumption and BMI. And the significant factors for SBP were age, BMI.

This study was conducted to compare of dietary behaviors of young and temporary workers with older and permanent workers of single-person households. A questionnaire survey was conducted by purposive quota sampling(n=566) by age groups(20~59 years old) and status of workers(temporary workers, permanent workers and business owners). Compared to other age groups, 20s had lower average monthly income and cost of eating-out, and they rarely cooked at home and mainly bought food and groceries at convenience stores(p<0.001). This pattern was similar to temporary workers compare to other groups. This study will be meaningful as a basic data for creating a healthy living environment for temporary workers and 20s of single-person households.

Objectives: This study compared the dietary behaviors of single-person households when eating alone according to the employment pattern and age. Methods: A total of 566 people aged 20~59 years old were collected from the status of workers and classified into three groups according to their employment pattern (regular, non-regular workers and business owner). The subjects were collected by purposive quota sampling on a Gallup panel from June to November in 2017. The dietary behavior and perception of eating alone of the subjects were surveyed via online and self-reported questionnaires. Results: The frequency of eating alone was significantly higher in the regular group than the non-regular group and business group (p<0.01). The place of eating alone was significantly higher in the regular and non-regular group in the convenience store, and business group in the office (p<0.001). Ramen, the menu when eating alone, was significantly higher in the non-regular group than the other groups (p<0.01). The preference for eating alone was lower in the older age group (p<0.05). The young aged group (aged 20~30) ate more fast food and felt more convenience than the older aged group aged 40~50 years (p<0.05). Conclusions: Single-person households with a non-regular job have poorer dietary behavior in eating alone than those who had regular employment. In a situation of an increasing number of non-regular workers aged in their 20s and 30s, there is a high likelihood of social problems, such as health and poverty. This study highlights the need for a healthy food selection environment to improve the dietary life of single-person households with non-regular jobs for the diverse types of single-person households.

Objectives: This study aimed to establish a control group based on the big data from National Health Insurance Service. We also presented presented the number of incidences for each cancer, and analyzed the cancer incidence rate among Korean workers. Methods: The cohort definition was separated by 'baseline cohort', 'dynamic cohort', and 'fixed- industry cohort' according to the definition. Cancer incidence was calculated based on the Korean Standard Classification of Disease code. Incidence rate was calculated among the group of all workers and public officials. Based on the study subjects and each cohort definition, the number of observations, incidences, and the incidence rate according to sex and age groups was calculated. The incidence rate was estimated based on the incidence per 100,000 person-year, and 95% confidence intervals calculated according to the Poisson distribution. Results: The result shows that the number of cancer cases in the all-worker group decreases after the age of 55, but the incidence rate tends to increase, which is attributed to the retirement of workers over 55 years old. Despite the specific characteristics of the workers, the trend and figures of cancer incidence revealed in this study are similar to those reported in previous studies of the overall South Korean population. When comparing the incidence rates of all workers and the control group of public officials, the incidence rate of public officials is generally observed to be higher in the age group under the age of 55. On the other hand, for workers aged 60 or older, the incidence rates were 1,065.4 per 100,000 person-year for all workers and 1,023.7 per 100,000 person-year for civil servants. Conclusions: This study analyzed through health insurance data including all workers in Korea, and analyzed the incidence of cancer of workers by sex and age. In addition, further in-depth researches are needed to determine the incidence of cancer by industry.

Objective: The purpose of this study is to analyze the accident characteristics according to the gender of the injured workers in building cleaning and to reflect them in the Industrial Accident Prevention Policy. Background: An analysis of industrial accidents is an essential process for establishing systematic industrial accident prevention measures. In order to establish industrial accident prevention measures for workers effectively, it is necessary to analyze accident characteristics by job type for workers who do the same work. Method: In this study, we analyzed the accident characteristics of 1,645 janitors who were approved of work-related injuries in 2015. We also analyzed the characteristics according to gender by dividing them into worker-related factors and accident-related factors. Results: The accidents caused to the janitors showed different characteristics according to gender, age, work experience, agency of accident, and distribution of original cause materials. In other words, 70.2% occurred to workers over 60 years old and 56.2% occurred to unskilled workers with less than a year of work experience. In the case of accident pattern, 79.1% occurred in tripping (slip) hazards, and 68.2% of accidents occurred on the floor (including the ground) and the stairs, indicating that the accident occurred most frequently during cleaning work on the floor or stairs. Conclusion and Application: The results of the study on the accident characteristics of the janitors can be used as basic data for systematic preventive measures against accidents occurring to the elderly female workers in the service industry.

A questionnaire survey of farmers engaged in actual farming was conducted to investigate the farmers' actual wearing conditions and preferences for agricultural workwear to develop workwear that is suitable for improved agricultural work efficiency. We extracted basic data necessary for the development of agricultural workwear. Analysis of the photographs taken showed differences in the shoes and gloves worn depending on the type of work. The percentages of men and women were equal among the agricultural workers. The age of the agricultural workers was analyzed and the results showed a higher percentage of those over 50 years old, indicating that the age of the agricultural workers was higher than in other industries. It was found that the waist, knees, and elbows of the workers were pulled during work, and analysis showed that the symptoms resulting from clothing pulling were more severe when the wearing dimensions were larger. It was recognized that the important aspects of workwear are those related to work, such as functionality, activity, and work efficiency. In addition to workwear, the most commonly worn auxiliary equipment was gloves, and other items included hats, armbands, work shoes, boots, seat chairs, and masks. When developing rural workwear, it is necessary to consider the fit, type of work, and materials of the workwear. Future research should focus on materials that can improve the functionality of workwear and pattern development that reflects physical and movement characteristics.

Purpose: This study compared factors related to fear of falling among women in the early phase of old age based on hand grip strength. Methods: Researchers obtained data of 1,071 women who had participated in the 4th Korean Longitudinal Study of Aging. Data were analyzed using multiple regression analysis. Results: In both groups, fear of falling was positively correlated with falling experience within two years, osteoarthritis-related leg pain, depression, and instrumental daily life abilities; however, self-rated health was negatively correlated. In the low hand grip strength group, self-rated health, osteoarthritis-related leg pain, and hand grip strength accounted for 21.3% of the variance regarding fear of falling. In the normal hand grip strength group, age, self-rated health, fall experience within two years, osteoarthritis-related leg pain, and depression significantly accounted for 16.6% of the variance regarding fear of falling. Conclusion: In applying interventions to prevent falling in women in the early phase of old age, health care workers must verify if women have low hand grip strength and determine whether to focus on fitness improvement through exercise interventions or consider psychological interventions for depression.
