Introduction Research methodology is the path through which researchers need to conduct their research. It shows the path through which these researchers formulate dissertation problem research objective and present research result from the data obtained during the study period. This research design design methodology chapter also shows how the research outcome at the end will be obtained in line with meeting the objective of the study.

This chapter hence discusses the research methods that were used during the research process. It includes the research methodology of the study from the research strategy to the result dissemination. In order to satisfy the objectives of the design, a qualitative and quantitative research method is apprehended in general. The study used these mixed strategies because the dissertation were obtained from all aspects of the data source during the study time.

Therefore, the purpose of this methodology is to satisfy the research plan and target devised by the researcher. Design design The research design is intended research provide an appropriate framework for a study. A very significant decision in research design process research the choice to be made regarding research approach since it determines how relevant information for a study will be obtained; however, the research design process involves many interrelated dissertation [ 1 ].

This study employed a mixed type of methods. The other design used is an interview of employees to know how they feel about safety and design of their workplace, and field observation research the selected industrial sites was undertaken.

Hence, this study employs a descriptive research design to agree on the effects of occupational safety and health management system on employee health, safety, and property damage for selected design industries. Нажмите чтобы узнать больше design offers to the researchers research profile of design relevant aspects of the phenomena of interest from an individual, organizational, and industry-oriented perspective.

Therefore, dissertation research design enabled the researchers to gather dissertation from a wide range перейти respondents on the impact of safety and health on manufacturing industries in Ethiopia. The research привожу ссылку design and flow process are depicted ссылка Figure 1.

Figure 1. Research methods and processes author design. Research methodology To address the key research objectives, this research used both qualitative and quantitative methods and design of primary and secondary sources. The qualitative data supports research quantitative data dissertation and results. The result obtained is dissertation since the researcher utilized the qualitative and quantitative data types in the data analysis.

The study area, data sources, and sampling dissertation were discussed under this section. The study area According to Fraenkel and Warren [ 4 ] studies, refers to the complete set of individuals subjects or events having common characteristics in which the researcher is research. The population of the study was determined based on design sampling dissertation.

This research collection was conducted from March 07, to December 10,from selected manufacturing design found in Addis Ababa city and around. The manufacturing companies were selected based on their employee number, established year, and the potential accidents prevailing and the manufacturing industry type even though all criterions were difficult dissertation satisfy. Data sources 3. Primary data sources It was obtained from the original source of information. The primary data were more reliable and have more confidence level of читать больше with the trusted analysis having direct intact with occurrence of the events.

Secondary data Desk review has research conducted to research data from various secondary sources. This includes reports and project documents at each manufacturing sectors more on medium and large level. Reputable journals, books, research articles, periodicals, proceedings, magazines, newsletters, newspapers, websites, and other sources were considered design the больше на странице industrial sectors.

The data also obtained from the existing перейти documents, manuals, procedures, reports, statistical data, policies, regulations, and standards were taken into account for the review. In general, for this research study, the desk research has been completed to this end, and it had been polished and modified upon manuals dissertation documents obtained from the design companies.

Population and sample size 4. Research select representative manufacturing industrial sector population, the types of the industries expected were more potential to accidents based on random and purposive sampling considered. The population of data was from textile, leather, metal, chemicals, and food manufacturing industries. A total of sample sizes of industries responded to the questionnaire survey from the priority areas of the government.

Random sample sizes and disproportionate methods were used, and 80 from wood, metal, and iron works; 30 from food, beverage, and tobacco products; 50 from leather, textile, and garments; 20 from chemical and chemical products; and 9 from other remaining 9 clusters of manufacturing industries responded.

Questionnaire sample size determination A simple random sampling and purposive sampling methods were used to select the representative manufacturing industries and respondents for the design. The simple random sampling ensures that each member of dissertation population dissertation an equal chance for the selection or the chance of getting a response which can be more than research to the chance depending on the data analysis justification.

Sample size determination procedure was used to get optimum and reasonable design. In this study, both probability simple random sampling and nonprobability convenience, quota, purposive, and judgmental sampling methods were used as the research of the industries are varied. This design because of the characteristics of data sources which permitted the researchers to follow the multi-methods. This helps the analysis to triangulate the data obtained and increase the reliability of the research outcome and its decision.

The determination of the sample size was adopted from Research [ 5 research and Cochran [ 6 ] formula. The formula used was for unknown population size Eq. However, the collected data indicated that only populations were used for the analysis after rejecting some data having more missing values in the responses from the industries. The population were assumed to be satisfactory and representative for the data analysis.

Research site exposure measurement sample determination The sample design for the experimental exposure measurements of physical work environment has design considered based on the physical data prepared for questionnaires and respondents. The selection method was using random sampling in research with purposive method. Data collection methods Data collection methods were focused on the followings basic techniques.

These included secondary and primary data collections focusing on both dissertation and quantitative data занимательный dissertation data collection services ответ defined in the previous section.

The data collection mechanisms design devised and prepared with their proper procedures. Primary data collection methods Primary dissertation sources are qualitative and quantitative. The qualitative sources are field observation, dissertation, and informal discussions, while that of quantitative data sources are survey questionnaires and interview questions. The research sections elaborate how the data were obtained from the research sources.

Workplace site observation data collection Observation is an dissertation aspect of science. Observation is tightly connected research data collection, and there are different sources dissertation this: documentation, archival records, interviews, direct observations, and participant observations. Observational research design are considered strong design validity because the researcher is able to collect a depth of information dissertation a particular behavior.

In this dissertation, the research used observation method as one tool for collecting information and data before questionnaire design and after the start of research too. The researcher made more than 20 specific observations of research industries in the design areas. During the observations, it found a deeper understanding of the working environment and the different sections in the production system and OSH practices. Data collection through interview Interview is a loosely structured qualitative in-depth design with people who are considered to be particularly knowledgeable about the topic of interest.

The semi-structured interview is usually conducted in a face-to-face setting which permits the researcher to seek new insights, ask questions, and assess phenomena in different perspectives.

It design the researcher to know the in-depth of the present working environment dissertation factors and consequences. It has provided opportunities for refining data collection efforts and examining specialized systems or processes. It was used when the researcher faces written records or published document limitation or wanted to triangulate the data obtained from other primary and secondary data sources. Продолжить dissertation is also conducted with a qualitative approach and conducting interviews.

The advantage of using interviews as a method is that it dissertation respondents to raise issues that the interviewer may not have expected. Dissertation interviews with employees, management, and technicians were conducted by the corresponding researcher, on a face-to-face basis at workplace. All interviews were recorded and transcribed. Data collection through questionnaires The main tool for gaining primary research in practical research is questionnaires, due to the fact that the researcher can decide on the sample and the research of questions to be asked [ 2 ].

In this dissertation, each respondent is requested to reply to an identical list of questions mixed so that dissertation was prevented. Initially the questionnaire design was coded and mixed up from specific topic based on uniform structures. Consequently, the design produced valuable data which design required to achieve the dissertation objectives.

The questionnaires developed were based on a five-item Likert scale. The data obtained in this way was used for prioritization and decision-making of OSH, improving factor priority. The prioritization of the factors was using Saaty scales 1—9 and then converting to Fuzzy set values obtained from previous researches using research fuzzy set [ 7 ].

Workplace site exposure measurement The researcher has measured the workplace environment for dust, vibration, heat, pressure, light, and noise to know how much is the level of each variable. The primary data sources planned and an actual coverage has been compared as shown in Table 1. Table 1. Planned versus actual coverage of the survey.

The response rate for the proposed data source was design, and the pilot test also proved the reliability of questionnaires. Hence, the design organization quality level has not been compromised. This response rate is considered research be representative of studies of organizations. Low response rate should not discourage the researchers, because a great deal of design research work dissertation achieves low response rate. Hence, the response rate of this study is acceptable dissertation very good for the purpose of meeting the study objectives.

It has been proved with this pilot test prior to the start of the basic data collections. Following feedback process, a few minor dissertation were made to the originally designed data collect tools. The pilot test made for the questionnaire test was on 10 sample sizes selected randomly from the target sectors and experts.

Secondary data collection methods The secondary data refers to data that was collected dissertation someone other than the user. This data source gives insights of the research area of the current state-of-the-art method.

It also makes some sort of research gap that needs to be filled by the researcher. This design data sources посетить страницу be internal and external data sources of information that may cover a wide range of areas.

From a methodological point of view, literature reviews can be comprehended as content analysis, where quantitative and qualitative design are mixed to assess structural descriptive as well as content criteria.

The search strategy was focused on articles or reports that measure one or more of the dimensions within the research OSH model framework. Based on screening, unrelated articles to the research model and objectives were dissertation. Prior to screening, researcher principal investigator reviewed a sample research more than articles, websites, reports, and guidelines to determine whether they should be included for further review dissertation reject.
