Ethics may be conceptualized as a special case of norms governing an individual or social action. As a researcher, you have an overriding obligation to protect participants’ welfare and safety and to ensure they are treated fairly and with respect. Research participants’ rights are anchored in fundamental human rights and the fundamental ethical principles that govern all scientific research. The basic ethical principles that have evolved to protect human participants from harm, apply to all fields of research in which humans participate by contributing time, effort, insights, and personal data for researchers’ use. 

2，Deontology: "In modern Western ethics, the moral theory that human behavior must follow certain moral principles or act in accordance with certain justifications." This theoretical system focuses on the motive of moral behavior, does not focus on the consequences of behavior, but resorts to certain rules, norms and standards of behavior, and the core of its theory is obligation and responsibility.
Example:Christians believe that behavior is morally correct as long as it conforms to the rules and obligations established by God.
Utilitarianism holds that one should perform an act that "reaches the greatest good," and that the calculation of the greatest good depends on the sum of the bitter feelings of each individual involved in this action, each of which is considered to have the same weight, and pleasure and suffering can be converted, and suffering is only "negative happiness." Unlike general ethical doctrines, utilitarianism does not consider the motives and means of a person's actions, but only considers the effect of the results of one action on the maximum happiness value.
Example:The rules of the market economy are all utilitarian rules, rules set for the greatest sum of social welfare.


3. There are a few reasons why it is critical to follow moral standards in inquiry about. To begin with, standards advance the points of inquire about, such as information, truth, and evasion of mistakes. For cases, denials against creating, adulterating, or distorting inquires about information advance the truth and minimize mistake.

Deontology is an ethical theory that uses rules to distinguish right from wrong. People are required to follow rules and fulfils obligations，not to lie and cheat.Deontology states that an act that is not good morally can lead to something good, For example, shooting the intruder (killing is wrong) to protect your family (protecting them is right).

3.First, norms promote the aims of research, such as knowledge, truth, and avoidance of error. Second, ethical standards promote the values that are essential to collaborative work, such as trust, accountability, mutual respect, and fairness. Third, ethical norms help to ensure that researchers can be held accountable to the public. Fourth,  ethical norms in research also help to build public support for research. Lastly, many of the norms of research promote a variety of other important moral and social values, such as social responsibility, human rights, and animal welfare, compliance with the law, and public health and safety.

   Utilitarianism would say that an action is right if it results in the happiness of the greatest number of people in a society or a group. A rather extreme example would be harvesting the organs of a healthy man to save five people.

3. 

   We take ethical consideration into works since ethical standards promote values essential to collaborative work, such as trust, responsibility, mutual respect and fairness.
 
   For example, many ethical norms in research, such as authorship guidelines, copyright and patent policies, data sharing policies, and confidentiality rules in peer review, are designed to protect intellectual property interests while encouraging collaboration.

3.The study of the social sciences is people-centred and is intended to promote the co-development of the individual and society. Compliance with ethical laws facilitates the regulation of all relations in society and the relationship between society and nature.

The informed consent process is designed to give every participant the liberty to decide whether to accept or refuse the recommended medical treatment. Sometimes their decision for participating in researcher projects is influenced by the religious beliefs. It is commonly observed that how the methodology of the experiment come into conflict with the rules of behavior set by a participant's religion                    Patient Perceptions

Most patients believe that, trials will put extra burden on them. They assume that the conventional treatment is best and they are afraid of the unknown side-effects of new treatment. Convincing and receiving informed consent from such a patient is most difficult. In some case disclosing too much information of the potential side-effects may unnecessarily scare the patient away from a potentially life-saving or life-enhancing surgery or procedure

4.The definition of consent refers to human participants who can enter research freely (voluntarily) with full information about what it means for them to take part and that they give consent before they enter the research.

The definition of coercion refers to the act of persuading or convincing someone to do something using force or other unethical means. When you threaten someone harm if they do not sign a contract, this is an example of coercion.

5.Researchers can withhold information from research participants or give them false information in order to carry out their research. That would be called a covert observation as the group being studied would not be aware of a researcher's observations. In this case, the research goes 'undercover' in order to gain valid data that is not influenced by the awareness of the participants'. In an overt observation, the participants are aware, which reflects the rights they have concerning their participation, but their awareness can risk the validity of the research in itself.

2. The informed consent process has been viewed as vital both to safeguard persons from harm and to maintain the foundation of autonomy as a right in and of itself by allowing potential participants to make their own decisions.

3.Language barriers are assumed that the individual who signs the consent form does so with a full understanding of what is stated on the consent form. However, it is very difficult to evaluate their viewpoint about the trial since there is no established method to measure the level of understanding that a participant has about the information given. The informed consent process is sometimes treated as a ‘now-size fits all’ Clinics don’t always provide the ideal setting to engage in meaningful discussions with potential participants. A common misconception about the process. 

Solutions: 

- Be prepared to explain the study to potential participants.

- Be familiar with the clinical environment. 

- Be respectful of patients and family. 

4.Informed consent is a process in which subjects voluntarily choose whether to participate in the study after fully obtaining and understanding the relevant information of the study. The purpose of informed consent is to protect the legitimate rights and interests of subjects and researchers. The behavior of being forced to participate in the study without knowing the harm and deciding is the behavior of being coerced.
For example, in medical experiments, the patient's surgical process will be displayed, that is, he will participate in the surgical demonstration. Doctors need to ask patients to sign informed consent under the permission of the law. If they lack this step, it will constitute coercion.

5. In general, deception is not acceptable in human studies. Occasionally, it is necessary to mislead the participants who are subjects of a study in order to obtain unbiased information. The Institute Review Board (IRB) must review very carefully the proposals that use deception or misrepresentation. Overt Observation occurs when the people being researched are aware that they are being watched. Covert Observation - when the group being researched is unaware that they are being watched, or when the research is conducted "undercover."

2. 

   Its necessity lies in the fact that it is crucial for voluntary subjects to decide if they accept the simulations, experiments, tests, or take part in trials. It is immoral to un-inform a volunteer of risks that may take place during these experiments since this alters the autonomy the volunteer has to make a sound and personal judgement to avoid potential risks and harm, doing such would be deliberately lying and it is immoral, therefore informed consent is necessary.

3.

   The main concern is the delivery of information. Let it know the complete information including the nature of the matter, etc. Then let it make a decision after it is fully informed. Solution: Retain vigilance on the verification of information. Make a decision after full understanding.

4.

   we can withhold information from our research participants.

   If people are unaware that they are the objects of sociological study, they have not given informed consent. It might be possible, in some cases, to get consent after the study has taken place, or to receive general consent

5.

   researchers can withhold or mislead participants with wrong information in the name of research.

   Covert observations are researches that In this instance, the research is conducted under covert means, to avoid attraction and awareness from participants in order to record genuine unbiased data that unaffected by awareness the participants would have in overt observations. Overt observation represents the validity of the subjects' rights to be informed and privacy but since they are aware they may be biased and acting unnaturally.

a person freely choosing to engage in a research study after being told of all components of the study and having full awareness of what their involvement entails and the risks connected with it is known as informed consent.

2. informed consent is essential on prevention of later study withdraw or misunderstanding about the study. It protects individuals from harm in creating a systematic security barrier for their well being, which also gives permission for potential stakeholders to participate with autonomous decision as a basic right. 

When it comes to acquiring informed consent, there are numerous problems. The informed consent process can be overly lengthy, convoluted, and written at a reading level beyond most potential participants' comprehension. Phase one or phase two trials of non-adjuvant or adjuvant therapy, for example, can be found in the permission document, which can contain a lot of scientific-technical and legal language.
