This study was carried out to investigate awareness and attitude of monitors in 206 small sized industries in Seoul and Kyeonggi area toward the occupational health programs using a specially prepared questionnaire. The industries had been running Government-Funded Subsidiary Program since 1998. The questionnaire was designed to be self-administered by respondents. Data were collected for two months from November to December, 1998. Major results are as follows: 1. Between two groups of industries, there were no significant differences in classification, scale, methods of production, existence of trade union, but in type of working pattern and facility ownership there were significant differences. 2. Between two groups of monitors, there were no significant differences in gender, age, marital status, rank, years of education, but in duration of working there was a significant difference. 3. In awareness and attitude of monitors toward their activities and occupational health programs, there was no significant difference by groups of industries, but a significant difference by type and scale of industry, gender, age, years of education 4. It was found that newly subsidized industries were more necessary to provide education programs on occupational health than old industries, and there was a significant difference between two groups of industries in the contents of education needed. In conclusion, it is desirable that the government should develop specific training programs for monitors on occupational health to provide them practical knowledge and specific skills which monitors can apply to their specific situation, and implement the training programs and continue Government-Funded Subsidiary Program for years until small scale industries would have been able to develop and keep their own health management system spontaneously.

The purpose of this study was to investigate the current status of pre-service curriculums for child care teachers at universities and colleges in Korea. To accomplish this, a survey was implemented to gather the lists of courses from each department training pre-service child care teachers. A total of 225 departments at universities and colleges across Korea participated in the survey. The results showed that the 37 different courses offered for child-care teacher licensure were different by school type (university or college) and major. Departments in colleges with specific majors such as early childhood education and social welfare offer courses that are also required for other certificates, including kindergarten teachers or social workers, so pre-service child care teachers may not have the opportunity to take courses specifically designed for their specific teaching needs or interests. Accordingly, there may be a restricted number of courses from which to choose during pre-service training periods. Based on the findings from this study, several political implications for improving child-care teacher professionalism were suggested.

With the development of concrete technology, producing concrete products that have the ability to flow under their own weights and do not need internal or external vibrations is an important achievement. In this study, assessments are made on using travertine, marble and limestone rock flours in self-compacting lightweight concrete (SCLC). In fact, the effects of these powders on plastic and hardened phases of SCLC are studied. To address this issue, concrete mixtures with water to cementitious materials ratios of 0.42 and 0.45 were used. These mixtures were made with 0 and 10% silica fume (SF) replacement levels by cement weight. To achieve lightweight concrete, lightweight expanded clay aggregate (Leca) with the bulk density of about $520kg/m^3 $was utilized. Also two kinds of water were consumed involving tap water and magnetic water (MW) for investigating the possible interaction of MW and rock flour type. In this study, 12 mixtures were studied, and their specific weights were in the range of $1660-1692kg/m^3$. To study the mixtures in plastic phase, tests such as slump flow, J-ring, V-funnel and U-box were performed. By using marble and travertine powders instead of limestone flour, the plastic viscosities and rheology were not changed considerably and they remained in the range of regulations. Moreover, SCLC showed better compressive strength with travertine, and then with marble rock flours compared to limestone powders. According to the results of the conducted study, MW showed better performance in both fresh and hardened phases in all the mixes, and there was no interaction between MW and rock flour type.

Objectives: The aim of this study was to propose a standardized guideline for clinical training courses among dental hygiene departments of colleges in Korea. This study comparatively evaluated periods and durations of the curricula and specific domains, credits and hours of clinical training classes, and institutions providing practical lessons, and calculated the total credits and hours. Methods: From August 15 to September 15, 2017, a literature review was conducted in dental hygiene departments of 82 schools around the country in order to investigate the current conditions of clinical training in each educational system. Furthermore, 5 colleges were selected from each type of educational system, and their credits and hours for clinical training were analyzed in subjects of practical training for clinical dental hygiene, practical training for dental clinic, practical training for local community dental health, clinical training, and pre-clinical level practical training. The total credits and hours were calculated on the basis of analysis results. Results: The findings revealed that the hours of clinical training classes and hours per credit for practical training in the dental hygiene departments as well as the practical training institutions varied between the colleges. In some cases, the hours of practical training were not indicated. Standardized clinical training in the dental hygiene department was allotted 675 hours, whereas practical training in local community dental health studies was allotted 105 hours, which totaled to 780 allotted hours. Conclusions: There was a significant difference among the colleges in terms of the current conditions of clinical training in the dental hygiene department. The literature review revealed that a total of 780 hours was allotted to clinical training, and this was significantly more than the standard (500 hours) set by the. Moreover, these clinical training hours were lower than in advanced countries or other health and medical treatment occupations. Therefore, efficient improvement is required in order to provide a timely guideline for clinical training.

In this study, the reliability analysis of internal and external stabilities of Reinforced Soil Walls (RSWs) under static and seismic loads are investigated so that it can help the geotechnical engineers to perform the design more realistically. The effect of various variables such as angle of internal soil friction, soil specific gravity, tensile strength of the reinforcements, base friction, surcharge load and finally horizontal earthquake acceleration are examined assuming the variables uncertainties. Also, the correlation coefficient impact between variables, sensitivity analysis, mean change, coefficient of variation and type of probability distribution function were evaluated. In this research, external stability (sliding, overturning and bearing capacity) and internal stability (tensile rupture and pull out) in both static and seismic conditions were investigated. Results of this study indicated sliding as the predominant failure mode in the external stability and reinforcing rupture in the internal stability. First-Order Reliability Method (FORM) are applied to estimate the reliability index (or failure probability) and results are validated using the Monte Carlo Simulation (MCS) method. The results showed among all variables, the internal friction angle and horizontal earthquake acceleration have dominant impact on the both reinforced soil wall internal and external stabilities limit states. Also, the type of probability distribution function affects the reliability index significantly and coefficient of variation of internal friction angle has the greatest influence in the static and seismic limits states compared to the other variables.

This study was conducted with the aim of constructing a unified model according to the structure of qualification types of lifelong education professionals for the disabled. The research method consisted of procedures in which literature analysis and expert meetings were constructed in connection with each other. The contents of the study were suggested from the classification of qualification types into professional teacher type and coordinator type by focusing on special education and rehabilitation, which are related convergence fields that affect the qualification training of lifelong education professionals for the disabled. The two convergence fields, such as special education and rehabilitation welfare, lead to a separate application base from the perspective of education and welfare for the qualification of lifelong education professionals for the disabled, and finally confusion and conflict in the nature and contents of the curriculum and related services. A dichotomy structure system in which this phenomenon results in a divided type of qualification training for lifelong education professionals with disabilities was composed of several samples. In this regard, the curriculum and related services that can build convergence fields related to lifelong education for the disabled were reflected in the context of priority through the criteria that should be emphasized from the standpoint of the disabled in the overall category of establishing lifelong education support system for the disabled. In addition, by forming four qualification criteria centering on this, the common convergence field was composed of special education, thereby enhancing the aspect of inclusion in the rehabilitation welfare field and specific convergence into lifelong education for the disabled. As a result, the two qualification types were unified.
