Background: This study aims to derive the characteristics of each work type for industrial radiography based on empirical evidence through expert advice and a survey of radiation workers of various types of industrial radiography. Materials and Methods: According to a Korean report, work types of industrial radiography are classified into indoor tests, underground pipe tests, tests in a shielded room (radiographic testing [RT] room test), outdoor field tests, and outdoor large structure tests. For each work type, exposure geometry and radiation sources were mainly identified through the expert advice and workers' survey as reliable empirical evidence. Results and Discussion: The expert advice and survey results were consistent as the proportion of the work types were high in the order of RT room test, outdoor large structure test, underground pipe test, outdoor field test, and indoor test. The outdoor large structure test is the highest exposure risk work type in the industrial radiography. In most types of industrial radiography, radiation workers generally used ¹⁹²Ir as the main source. In the results of the survey, the portion of sources was high in the order of ¹⁹²Ir, X-ray generator, ⁶⁰Co, and ⁷⁵Se. As the exposure geometry, the antero-posterior geometry is dominant, and the rotational and isotropic geometry should be also considered with the work type. Conclusion: In this study, through expert advice and a survey, the external exposure characteristics for each work type of industrial radiography workers were derived. This information will be used in the reconstruction of organ dose for health effects assessment of Korean radiation workers.

The purpose of this study is to examine the Korean social workers' level of social work values, advocacy attitude and advocacy intervention, and to verify the relations among social work education, social work advocacy and social work values by examining whether social work education influences social work advocacy and social work values, and whether social work values affect social work advocacy. Further, this study wishes to confirm not only the direct effect that social work education has on social work advocacy, but also how social work education indirectly influences social work advocacy through social work values on the social level as a mediator. The research of this study was conducted on 461 social work practitioners who have obtained either social worker licenses or mental health social worker licenses and are currently working in the field. As survey tools, this study utilized social work advocacy attitude, social work advocacy intervention, outcomes of social work education, social work values, self-esteem and locus of control. Collected data were analyzed by using SPSS/PC+ 11.5 for one-way ANOVA and t-test, Pearson's correlation, reliability analysis, exploratory factor analysis and multiple regression. To sum up the results of the study in terms of the research hypothesis, the research hypothesis was established according to the analysis method of the testing mediation of Baron & Kenny (1986) in order to examine whether social work values on the social level intervene between social work education and social work advocacy. The results of the hypothesis test confirm that social work values on the social level serve as a mediator variable.

This study evaluated the characteristics and sensibility of work clothes materials developed that took into account the work environment of major industrial settings, for which a selection was made according to spring/autumn use and winter use. The physical properties of the existing and test weaving of the work clothes materials were compared after the test weaving of work clothes materials through material design, which altered the yarn count, composition, weave and density of material. To evaluate sensibility of work clothes materials subjectively, seven ranks' semantic differential scale questions were developed with polar adjective pairs. The test weaving of work clothes materials showed improved performance (such as tensile strength, dimensional change, water vapor permeability, and color fastness) compared to the existing materials. The common factor analysis indicated that the explanatory power of the cumulative variance for the spring/autumn use and winter use was 71.19% and 69.53%, respectively.

The objective of this study was to investigate the physical work capacity and rest allowance for Korean males and females. Eleven males and 13 females participated in the study as subjects. An ergometer exercise test and a treadmill exercise test were conducted to measure oxygen consumption rates. The PWC values of Korean males and females were 2605.62ml/min and 1853.01ml/min in the cycle ergometer test, respectively, and 2872.10ml/min and 2057.91ml/min in the treadmill test. The PWC values of Korean females were about 70% of Korean males. The PWC values of Korean females were74.36%-78.79% of western males in the treadmill test. and 88.66%-89.32% of western males in the ergometer test. The PWC values of Korean females were 81.34%-82.98% of western females in the treadmill test, and 87.11% of western femaleles in the ergometer test. And, the results of this study showed that the rest allowance should be determined separately for male and female because of the difference in physical work capacity.

Instrumental and sensory characteristics of chewing gums were measured at each masticatory stage, and the correlations between the characteristics were analyzed. In instrumental characteristics, similarities were proved between initial puncture work and puncture force, intermediate hardness and penetration work, final hardness and penetration work, and adhesion work and adhesion force. Final hardness correlated highly with yield force and the slope of force-distance curve of penetration test, and the slope also correlated significantly with springiness and adhesion force. In sensory characteristics, the correlations of the same parameter between trained panel and consumer were extremely high. Initial stiffness correlated significantly with both intermediate and final firmness by consumer. Highly significant correlations were obtained between final firmness and stiffness and between lift and cohesion by trained panel, whereas firmness correlated with adhesion negatively.

This study was conducted by the slump test and the consistency test of the fiber mixed soil which is soil reinforced with fiber as a reinforced material to investigate and estimate the difficulty degree of work and the proper water content. So I would like to present the fundamental data that establishes the work standard of the fiber mixed soil. In conclusion, in this study the slump value of the fiber mixed soil increases over-all according to the increase of the water content although it has a little difference of the increase range and it is smaller than one of the soil. It is estimated that the aggregating and throwing work of the fiber mixed soil would be fine when it has the about 25 % water content and the wall and floor plastering work is the about 30 % ~ 35 % and the flowing and pouring work is the about 40 % water content as well as the mold compacting work is the about 20 %. There is no decreasing of the workability when the soil is reinforced by the fiber because the workability characteristics of the fiber mixed soil is similar to the one of the soil. Therefore, It is estimated that using the fiber as a reinforced material of soil would be appropriate for the construction.

Purpose:This study aimed to identify the effect of work interruption that influenced workload and perception of patient safety culture on ward nurses. Methods: Participants were 184 ward nurses, with more than 12 months of work experience, from two tertiary hospitals in S city. A descriptive correlational study design was used. Collected data were analyzed using descriptive statistics, t-test, ANOVA, Mann-Whitney U test, Kruskal-Wallis test, Pearson's correlation, and hierarchical multiple regression analysis via SPSS version 27.0. Results: The results showed that general wards nurses had a higher degree of work interruption (t=5.632, p<.001) and workload (t=3.603, p<.001) compared to comprehensive nursing care service wards nurses. More interruption in nursing work caused more burden on work (γ=.440, p<.001) and led to lesser perception of patient safety culture (γ=- .199, p=.007). Finally, the regression analysis showed that work interruption had a statistically significant relevance on nurses' workload (F=20.582, p<.001) and perception of patient safety culture (F=8.792, p<.001). Conclusion: To alleviate ward nurses' work interruption and decrease the negative effect on workload and perception of patient safety culture, it is necessary to mediate nurse staffing level and the number of assistants and utilize the environment.

The purpose of this study is to provide the basic information for the improvement of housewives consciousness and satisfaction of household work by analyzing the data regarding the housewives consciousness and satisfaction toward household work. The research problems was described as follows; 1) How independent variables influence the housewives consciousness of household work. 2) How independent variables influence the satisfaction of household work. 3) How relate the housewives consciousness and the satisfaction of household work. The research was conducted on 354 housewives in Seoul during the end of January and the beginning of March, 1986. As for the measurement of the instrument, questionnaire with 46 items was made by investigator. The data were analyzed by frequency, percentage, mean and t-test, F-test, Scheffe-test, Pearson-r. The results were summarized as follows; 1) Among the independent variables, the ages of housewives, durations of marriage, psychologica satisfaction were variables to have influence on the housewives consciousness towark household work. 2) Among the independent variable,s the socio-economic status, durations of marriage, psychological satisfaction were variables to have influence on the satisfaction of household work. 3) There were strong positive correlationship between the housewives consciousness and the satisfaction of household work. As a result, it is necessary to minimize the repetition and the overload of house-hold chores through the rationalization of household work and also to divide householdwork properly to family members. We let the housewives feel that her ability can be obtained from the household work. Especially the housewives must have a clear and a high level of consciousness of the household work an expect to receive high value of her household work from the family members. In order to do so, it seems to be important that housewives makes on great effort to have a positive value system and attitudes toward the consciousness and satisfaction of household work. We also must develop those factors through school and home education.
