Whilst Ecological momentary assessment (EMA) can provide important insights over time and across contexts among rotation workers whose work periods alternate with leave at home, it can also be challenging to implement in the resources and construction sectors. This review aimed to provide a summary of the methodological characteristics of EMA studies assessing health outcomes and related behaviors in rotation workers. Systematic searches in PubMed, Medline, EMBASE, CINAHL, PsycINFO, and Scopus were done to include 23 studies using EMA methods in assessing health-related outcomes and behaviors. EMA designs included daily diary: assessments once per day typically fixed at the end of day (47.8%), within day fixed interval time-based design: assessments on multiple times per day at certain times of day (17.4%) and combination of both designs (34.8%). Studies employed paper and pencil diaries (73.9%) and one or more electronic methods (60.9%): wrist-worn actigraphy device (52.2%) and online-based diaries (26.1%) for data collection. Most of the studies (91.3%) did not report prompting -EMAs by schedule alerts or compliance. Daily diary and within day fixed interval dairies designs are common, with the increasing use of electronic EMA delivery techniques. It is unclear how well participants adhere to assessment schedules, as these are inadequately reported. Researchers should report compliance-related information.

In Korea, researches on the exposure assessment of the hand-transmitted vibration started from the mid-90, however, they were performed in the limited industries such as auto-assembly plants and the evaluation of the vibration was mostly conducted by ISO 5349(1986). Therefore, it was necessary to assess hand-transmitted vibration levels of workplace such as ship building/repairing industry or mining industry where occupational injuries are largely occurred and to evaluate the vibration levels using revised ISO 5349(2001). The SVAN 949 Four Channels Sound & Vibration Analyser was used for the measurement. The workers using a chain saw were exposed to $1.7{\sim}2.8m/s^2$ of daily vibration level. Workers using a rock drill in a coal mining were exposed to the highest vibration acceleration among workers and the levels were $7.1{\sim}10.8m/s^2$. Vibration levels of grinders were different according to the types of grinders. The hand-transmitted vibration of 3 types of grinders were measured and the levels were $3.3{\sim}11.1m/s^2$. Workers using a impact wrench were exposed to $1.5{\sim}1.6m/s^2$ of vibration. Out of 20 kinds of machines, only 4 tools provided the information of vibration acceleration on the instructions. In addition, the current condition of workplaces to control vibration was not much different from the past because there are no vibration exposure limit.

Recently this writer has conducted a comprehensive survey of 38 private businesses where group feeding is practiced, with a view to determining the condition of nutrition intake by the blue collar workers of these businesses firms as well as gaining an indication of their facilities management along with their sanitary precautions. The survey has revealed, among others, a number of interesting data such as shown below. 1. There are a total of 1,054 workers being fed in groups daily at each of the above business companies, with only one nutrition specialist regardless of the number of workers to be fed or the number of times they are fed daily. The average number of cooks comes to 2.7 persons per 100 workers, while 42.2% of the companies provide four meals a day including mid-night supper, with the result that the workers are fed 3.13 times a day on an average. 2. The average feeding cost amounts to 151 won per meal per person, of which 86 won is payed by the workers themselves and 115 won by the companies involved. 3. The average fbod intake has been found to be 490 grams which can be further broken down into 44grams of animal food and 446grams of vegetable food. These figures are higher than those revealed by the 1975 investigation of the nation's average nutrition intake. 4. The survey also shows the daily calorie consumption per person to be as high as 896 calories including 37 grams of protein which is further broken down into 11 grams of animal protein and 26grams of vegetable protein. With respect to other types of nutrients excepting Vitamin-A, the companies concerned are believed to prorids more than what the survey of the nation's nutrition has revealed or the amount recommended by Korea FAO assoc!ation as desirable. 5. As for facilities management, there is still much room for future improvement. Some 97.4% of the companies surveyed are not equipped with the steam table, which indicates lack of concern along this line as well as a very how degree of equipment utilizations. Distribution of the food in the dining room is generally depedent on self-service method. 6. Speaking of sanitary precautions taken by those businesses involved, some 76.3% are found to have their compounds haunted by rats and other insects. Some 73.7% of them are dependent on boiling method for disinfection of kitchen utensils, which is conducted by 50% of those industries only two or three times a week. It seems hardly feasible to conduct disinfection everyday.

PURPOSE: This study examined the differences between male and female workers by investigating the various factors that affected the workers' abilities to return to work according to the International Classification of Functioning standards. METHODS: We analyzed the personal factor, environmental factor, work performance and participation factor related to ICF according to worker's gender. For this purpose data from the third Worker's Compensation Insurance panel survey conducted by the Korea Workers' Compensation & Welfare Service were analyzed. In order to verify the research model, we used frequency analysis, cross analysis to compare the differences between male and female workers according to personal, environmental, work performance, and participation factors and hierarchical regression analysis to identify significant factors affecting job performance. RESULTS: The results, indicate that the level of education, license status, working period, socioeconomic status and employment type of female workers were lower than those of male workers. Factors that have the greatest influence on job performance are grade of disability, status of disability, economic activity status, and instrumental activities of daily living (p<.05). CONCLUSION: It is necessary to provide socially stable employment support and social policy support without discrimination to allow disabled female workers to return to work and maintain their jobs and to study factors influencing job performance further.

The purpose of this study was to investigate social workers' personal experiences providing social support to multi-cultural family in a multi-cultural family center. The data were collected through in-depth interviews with 14 social workers at the multi-cultural family center, and were analyzed using a phenomenological research method. The major findings were as follows : The social workers' personal experiences with and understanding of social support were classified as 4 categories : 'source of emotional support to the multi-cultural family', 'diverse and systematic educational support', 'excessive demands on material support', and 'daily life support and connection with community network'. The social workers recognized emotional and educational support as essential factors in providing social support to multi-cultural family. However, the social workers' perceptions of material support derived from negative personal experiences stemming from excessive demands and misunderstanding for material support. These results showed that social workers at the multi-cultural family center provided multi-cultural families with social support and that they interacted with community support system and multi-cultural families to increase their satisfaction.

In this study, the authors introduced DASH (Disabilities of the arm, shoulder, and hand), which had been developed for evaluating the functional impairment in the movement of upper extremities in regular daily activities, work ability and sports/performing arts ability. It is an ergonomic risk assessment tool used for industrial workers and also a disability measurement tool for upper extremity disorders arising from musculoskeletal disorders and symptom. This study intended to examine the applicability of DASH in occupational health field. Firstly, DASH development process and composition were reviewed through The DASH outcome measure user's manual and early articles. Secondly, reliability, validity, and responsiveness of the DASH in various languages at the application stage as well as its reliability and validity at the early stage of development were investigated. Thirdly, focusing on the application of DASH to clinical cases, workers with musculoskeletal symptoms, healthy workers, workers with other diseases, and general population were discussed besides workers with major musculoskeletal disorders. Lastly, DASH questionnaire was examined for its potential as a reference for assessing the functional impairment in the movement of upper extremities of workers with musculoskeletal symptoms in industrial workers in Korea.
