This section provides an overview of problems identified in the research conducted by the sun coast and presents the research objectives, related questions and hypotheses.

Research problems

As discussed in the previous section main problems identified are related to health and safety of sun coast employees include noise, level of asbestos, training, intake of lead and the return on investment from different training programs. The problem with particulate matter (PM) is that those less than 2.5 microns can be inhaled and reach to lungs causing respiratory and other diseases. Therefore, measuring the PM size will help to understand its relationship with number of sick days taken from different sites.

Similarly, another health issue observed is lead exposure from lead remediation projects. The objective is based on the comparison of the amount of lead in blood measured in micrograms per deciliters (μg/dL) before and after the project. The comparison will help to know if the projects pose health damages by increasing the blood lead measures. Moreover, the measurement of sound-level (in decibels, dB) exposure is an important factor for the health of the workers. This will help the management to employ specific ear protection devices. Different factors hypothesized to increase the dB are checked for their relationship to higher decibels.

Measuring the success of safety training is important and is done so by recording the number of lost-time hours. The reduction in the number of lost-time hours with an increase in expenses of training will indicate the success of the training. The research also includes a comparison of two different training programs in separate groups. One group is exposed to the previous training program and other to the new. As given in the objective four below, comparing the effectiveness will provide information on which program is better and should be continued.

Lastly, the return on investment has been compared for water reclamation, air monitoring, soil remediation, and health and safety training projects. This comparison will tell which projects are generating higher revenue. Addressing these issues will help to know the root cause of the problems and will also aid in solving the issues for the progress of the company.

Research Objectives

Research objectives define the aims and main goals of the research and should be stated clearly before the start of the research ADDIN ZOTERO_ITEM CSL_CITATION {"citationID":"pmClwh1o","properties":{"formattedCitation":"(Farrugia, Petrisor, Farrokhyar, & Bhandari, 2010)","plainCitation":"(Farrugia, Petrisor, Farrokhyar, & Bhandari, 2010)","noteIndex":0},"citationItems":[{"id":115,"uris":["http://zotero.org/users/local/YjWHJPzk/items/B8V9JGXD"],"uri":["http://zotero.org/users/local/YjWHJPzk/items/B8V9JGXD"],"itemData":{"id":115,"type":"article-journal","title":"Research questions, hypotheses and objectives","container-title":"Canadian Journal of Surgery","page":"278","volume":"53","issue":"4","source":"Google Scholar","author":[{"family":"Farrugia","given":"Patricia"},{"family":"Petrisor","given":"Bradley A."},{"family":"Farrokhyar","given":"Forough"},{"family":"Bhandari","given":"Mohit"}],"issued":{"date-parts":[["2010"]]}}}],"schema":"https://github.com/citation-style-language/schema/raw/master/csl-citation.json"} (Farrugia, Petrisor, Farrokhyar, & Bhandari, 2010). The research objectives for this research are listed below:

RO1: To determine if there is a relationship between the size of PM (particulate matter) size and employee health.

RO2: To determine if the safety training has been successful to reduce the lost-time hours

RO3: To determine if the frequency, chord length, velocity and displacement can be used to predict dB levels.

RO4: To know if the revised training program is better than the prior training program.

RO5; To determine if there is any difference in the level of lead in the blood of employees before and after the lead remediation program.

RO6; To determine if the differences exist in return on investment for air monitoring, water reclamation, soil remediation, and health and safety training projects.

Research Questions and Hypotheses

The research question should be specific and broad enough to cover all the necessary aims of the research at the same time ADDIN ZOTERO_ITEM CSL_CITATION {"citationID":"WPwwnoQK","properties":{"formattedCitation":"(Boland, Cherry, & Dickson, 2017)","plainCitation":"(Boland, Cherry, & Dickson, 2017)","noteIndex":0},"citationItems":[{"id":93,"uris":["http://zotero.org/users/local/YjWHJPzk/items/GUTIK5NI"],"uri":["http://zotero.org/users/local/YjWHJPzk/items/GUTIK5NI"],"itemData":{"id":93,"type":"book","title":"Doing a systematic review: A student's guide","publisher":"Sage","ISBN":"1-5264-1658-1","author":[{"family":"Boland","given":"Angela"},{"family":"Cherry","given":"Gemma"},{"family":"Dickson","given":"Rumona"}],"issued":{"date-parts":[["2017"]]}}}],"schema":"https://github.com/citation-style-language/schema/raw/master/csl-citation.json"} (Boland, Cherry, & Dickson, 2017). The research questions and hypotheses, based on the above objectives, are given below:

H01: There is no statistically important association between PM (particulate matter) size and the number of sick leaves.

HA1: There is a statistically important association between PM (particulate matter) size and the number of sick leaves.

RQ2: Have the safety training sessions been effective in reducing lost-time hours?

H02: Safety raining has not been successful in reducing number of lost-time hours

HA2: Safety raining has been successful in reducing number of lost-time hours

RQ3: Do the variables like frequency, angel, chord length, velocity and displacement can be related to noise (dB)?

H03: The frequency, angel, chord length, velocity and displacement are not related to noise (dB).

HA3: The frequency, angel, chord length, velocity and displacement are related to noise (dB).

RQ4: Is there any difference in the effectiveness of the revised and prior training programs?

H04: The revised training has been effective than the prior training program.

HA4: The revised training has not been effective than the prior training program.

RQ5: Did the lead amounts in the blood of workers increase after the lead remediation project?

H05: The lead amounts in the blood of workers increased after the lead remediation project.

HA5: The lead amounts in the blood of workers did not increase after the lead remediation project.

RQ6: Is there any difference in the return of investment by water reclamation, air monitoring, health and safety training and soil remediation projects?

H06: A difference exists in the return of investment by the four projects.

HA6: No difference exists in the return of investment by the four projects.
