Objectives: This study was conducted to develop a model describing the interaction between lifestyle, job, and postural factors and parts of the upper extremities in shipyard workers. Methods: A questionnaire survey was given to 2,140 workers at a shipyard in Ulsan City. The questionnaire consisted of questions regarding the subjects' general characteristics, lifestyle, tenure, physical burden, job control, posture and musculoskeletal symptoms. The overall relationship between variables was analyzed by a structural equation model (SEM). Results: The positive rate of upper extremity musculoskeletal symptoms increased in employees who worked longer hours, had severe physical burden, and did not have any control over their job. Work with a more frequent unstable posture and for longer hours was also associated with an increased positive rate of musculoskeletal symptoms. Multiple logistic regression analysis showed that unstable posture and physical burden were closely related to the positive rate of musculoskeletal symptoms after controlling for age, smoking, drinking, exercise, tenure, and job control. In SEM analysis, work-related musculoskeletal disease was influenced directly and indirectly by physical and job stress factors, lifestyle, age, and tenure (p < 0.05). The strongest correlations were found between physical factors and work-related musculoskeletal disease. Conclusion: The model in this study provides a better approximation of the complexity of the actual relationship between risk factors and work-related musculoskeletal disorders. Among the variables evaluated in this study, physical factors (work posture) had the strongest association with musculoskeletal disorders.

Purpose: This study was to determine the effects of calcium intake on bone mineral density (BMD) in pre and post menopause women and to provide basic data for enhancing bone health of middle aged women. Methods: A total of 700 middle-aged women living in Seoul and Geonggi Province were interviewed during the period from June 2003 through January 2004 to investigate their social. demographic and physiological characteristics, health and daily activity performance, and their dietary patterns, and bone mineral density was measured. The survey of dietary intake was 24 hour recalls, and the individual calcium intake was calculated using food frequency. Data of 618 subjects was used for the analysis. Of the calcium intake levels, BMD values of the subjects of 20% of high level. 60% of middle level and 20% of low level were analyzed and compared. Results: The level of calcium intake according to general characteristics of the subjects was significantly related to age (p=0.001), education levels (p=.003) and marital status (p=.001). The BMD of the lumbar vertebrae and femur of the subjects taking a high level of calcium showed significantly higher than that of the subjects taking a middle level and low level of calcium. Femoral T-score was also significantly higher in subjects taking a high level of calcium than that of those taking a middle level and lower levels of calcium. Lumber spine T-score was higher in the high level group than that of the middle level group. Conclusion: The study revealed that women taking a high level of calcium had better bone health. Therefore. calcium intake is extremely important in daily dietary intake so that the intake of calcium-rich foods is highly recommended.

Purpose: This study was carried out to investigate the difference in job satisfaction and marital satisfaction by gender and to explore the influences of demographic status. employment characteristics. and job satisfaction/marital satisfaction on each type of satisfaction. Method: Social statistics survey data collected by National Statistical Office in 1998 were used for the secondary analysis in the study. Job satisfaction was measured by questionnaires, which consisted of 12 items such as task, promotion, placement, wage, benefits, future in the work, working environment, human relationship. and working hours. And marital satisfaction was collected by questionnaires which consisted of 7 items, including satisfaction with general family life, relationship with their own parent and parent-in-law, relationship with brothers and sisters, relationship with their children, and economic living status. These are measured by 5-point Likert scale. Result: The results show that more than 60% of women were working as part-time employees. Their education levels were lower than men. Men were satisfied significantly more in their jobs than women. Men also had higher marital satisfaction. The employment status had the most important factor on the job satisfaction. and the marital satisfaction was the second important factor among women and men. As for the age, while older men showed higher job satisfaction, younger women showed higher job satisfaction, 28.04% of the variance in the job satisfaction for men and 33.86% for women were accounted for by the following variables: the younger age. the higher education. job satisfaction, and the higher marital satisfaction, 22.15% of the variance in the marital satisfaction for men and 21.19% for women were accounted for by these variables. Conclusion: The results of this study showed that there were differences in job satisfaction and marital satisfaction between genders, and that job satisfaction and marital satisfaction influenced each other. Employment status was the most predictive factor on the job satisfaction. Married women had an unstable employment status such as part-time position. The stability of employment could be considered as a strategy for enhancing job satisfaction for both sexes. The reason that women had lower marital satisfaction than men will have to be further investigated.

There have been many researches on the characteristics of item trade. However, most researches were done by carrying out a survey and there has been few researches by analyzing the economy in online games. So, this article studied the cause of item trade by looking into the supply and demand of items in online games. The results shows that item trade is taking place mostly among only a few number of gamers who enjoy enchanting and who engage in castle sieges and blood pledge battles. The proportion of item trade by general garners is not so big. And major item providers are gold farms, not garners. Therefore, item trade is mostly carried out by a large number of garners who trade a small amount of sum and by a small number of heavy garners who trade large amount of sum. Understanding this characteristic of item trade would be a good ground for reviewing the policies and social effect regarding item trades.

The study aims to investigate the process of professional socialization of oriental medical students, to analyze influencing factors on it, and to compare the results with those of western medical students. Professional socialization, in the context of this study, means the process through which a layperson becomes a profession equipped with professional identity and values. A survey using specially designed questionnaire was carried out in 1999. The data were collected from 11 oriental medical colleges for 2,656 students. A total of 2,597 cases was finally included in the statistical analysis. Analysis of factors related to professional value found that oriental medical students thought highly of human-oriented factors, followed by science and status, and this trend remained unchanged as they moved on to qualification. Among professionalism related items, those involved in professional regulation and dominance factors showed high scores, while showing low scores on items related to bio-ethics and autonomy factors. Unlike items of professional value, those of professionalism showed a notable difference in attitude statistically by schooling level. The average scores of factors for professionalism increased with increasing schooling years. This trend proved that oriental medical students acquired professional norms and attitudes through their educational period. Multiple regression analysis with the factors related to professional value and professionalism as dependent variables found that independent variables had some impact on science, status, and clinical autonomy, but no impact on human, policy autonomy, and professional regulation factors. In conclusion, with increasing schooling years, professional norms and attitudes of oriental medical students were also strengthened. And, in spite of the differences in general propensity, they have a base consciousness in common with western medical students. The difference of mind-set and attitudes related to professionalism in the two groups, however, considering the necessity of future cooperative relations, indicated that a common curriculum between both schools is needed, and the education of social medicine should be strengthened in oriental medical colleges.

Today, the development of spaceborne Earth remote sensing is characterised by the increasing number and various types of remote sensing satellites, which are being operated in the low altitude and geostationary orbits with the help of rapid development of modern space technologies. It is believed that around 15 countries have programs to own their spaceborne Earth remote sensing systems, and the number of systems will be reached to some tens until the end of 2000 years. It is expected that Korean remote sensing satellites will be launched in sequence according to the national space program. The befinits will be magnificient because of the wide range of application area. Application of remote sensing information to the social infra implies that the potential customers can access the information, mission and the characteristics of the operation, and it is necessary to be supplied more information about systems and mission areas to our domestic users for proper applications. In this review we will survey the applications of the information acquired by the systems of USA, Russia and other countries. In this review we will discussed withing general application area, missions and systems.

As divorce and singlehood have been on the rise over the last decades, marital statuses are more diverse than the past for middle-aged men and women in South Korea. While marital status is crucial for health behaviors and statuses, but few studies examine the associations between health differentials and marital status for the middle-aged in South Korea. Using the 2010 Social Survey collected by the Statistics Korea, this study analyzes how health behaviors and statuses vary by the marital status. In particular, this paper examines whether marital statuses and gender interact to influence health behaviors and statuses. I find that married middle-aged people are healthier than divorced, single, and widowed middle-aged people. But this the negative influence of the non-married status are much greater for men than women. Some female non-married groups do not differ from married middle-aged people in some indicators of health behaviors. Single female middle-aged people are better in general satisfaction levels than married middle-aged people.

Objectives: Republic of Korea has entered an aged society, recently. As chronic diseases increase, elderly inpatients has been increasing and they have used caregivers for convenience. Accordingly, this study aims to investigate the oral health knowledge and attitude of caregivers on oral health management of elderly inpatients, which would affect the general health and quality of life. Methods: A survey questionnaire was distributed to the caregiver(n=165), at a neurosurgery or orthopedic hospital inpatient ward in Seoul, Gyeonggi-do from April 1 to 14, 2017. We analyzed the data with descriptive statistics analysis, chi-squared analysis and logistic regression analysis by using SPSS 23.0. Results: The response rate to the questionnaire was 92%. Oral health management provided by caregivers to inpatients in the elderly was prevention of oral diseases(92.8%), tooth brushing (89.5%), use of oral care products(68.4%), denture cleaning(90.8%) and oral cleaning(90.8%). Frequency analysis of oral health management in accordance with the educational needs of caregivers was all confirmed statistically significant(p<0.05). In the logistics regression model, oral health knowledge was significantly associated with low oral cleaning(OR=1.58) and oral health attitude was significantly associated with high denture cleaning(OR=1.29) and oral cleaning(OR=1.28) after adjustment for other covariates including gender, age, certification, education level, ward, working years. Conclusions: It is necessary to expand the scope and improve the quality of education that can change the attitudes and behaviors of the caregivers on the oral health management of the elderly on the basis of the current oral health education.

Objectives: The purpose of this study was to investigate public preferences regarding allocation principles for scarce medical resources in the coronavirus disease 2019 (COVID-19) pandemic, particularly in comparison with the recommendations of ethicists. Methods: An online survey was conducted with a nationally representative sample of 1509 adults residing in Korea, from November 2 to 5, 2020. The degree of agreement with resource allocation principles in the context of the medical resource constraints precipitated by the COVID-19 pandemic was examined. The results were then compared with ethicists' recommendations. We also examined whether the perceived severity of COVID-19 explained differences in individual preferences, and by doing so, whether perceived severity helps explain discrepancies between public preferences and ethicists' recommendations. Results: Overall, the public of Korea agreed strongly with the principles of "save the most lives," "Koreans first," and "sickest first," but less with "random selection," in contrast to the recommendations of ethicists. "Save the most lives" was given the highest priority by both the public and ethicists. Higher perceived severity of the pandemic was associated with a greater likelihood of agreeing with allocation principles based on utilitarianism, as well as those promoting and rewarding social usefulness, in line with the opinions of expert ethicists. Conclusions: The general public of Korea preferred rationing scarce medical resources in the COVID-19 pandemic predominantly based on utilitarianism, identity and prioritarianism, rather than egalitarianism. Further research is needed to explore the reasons for discrepancies between public preferences and ethicists' recommendations.
