Abstract

The COVID-19 pandemic has increased the frequency of using alcohol-based hand sanitizers, especially among health workers. This increase in the frequency of using hand sanitizers increases the incidence of contact dermatitis. The presence of allergens and reduced fat and water content in the skin causes contact dermatitis. This research was conducted to review more deeply how much influence the use of hand sanitizers has on the incidence of contact dermatitis for health workers in the COVID-19 era and to provide advice on the use of additional materials as well as the selection of materials and procedures for using hand sanitizers to reduce the incidence of contact dermatitis. A literature search was conducted from journal articles with a time span of 2012-2022 using databases in the form of Pubmed, Ebsco, Google Scholar, Hindawi, Medline and Science Direct (65 articles). We included 65 research articles that met the inclusion and exclusion criteria by analyzing the abstract and full text through tables together. Research shows that the use of alcohol-based hand sanitizers with high frequency and contains allergenic ingredients triggers the occurrence of contact dermatitis in health workers. So the use of additional ingredients such as moisturizers and the selection of alcohol-based hand sanitizer materials must be considered to reduce the incidence of contact dermatitis.

Abstract

This paper is motivated by the dynamics of religious pluralism that challenge the traditional understanding of Christ's uniqueness as Savior of the world, especially amidst the growing relativism of truth and interfaith dialogue. In this context, in-depth and argumentative theological reflection is essential for the Christian faith to remain relevant and accountable. This study aims to comprehensively examine the uniqueness of Jesus Christ from the perspective of Christology and Soteriology, and to examine how an apologetic approach can be used to explain and defend this doctrine rationally and contextually. The research method used is qualitative with a literature study approach and descriptive-analytical analysis, through the study of various theological sources, both the Bible and classical and contemporary academic literature. The results show that Christ's uniqueness lies in His identity as God incarnate as a human being and His final and universal work of salvation for humanity. From an apologetic perspective, this uniqueness can be explained through historical arguments regarding Christ's life and resurrection, as well as philosophical-theological reflections that affirm the consistency of the Christian doctrine of salvation. Furthermore, this approach allows for open dialogue without losing the integrity of faith. The research conclusion confirms that the uniqueness of Christ as the Savior of the world is the center of Christian faith which has a strong theological and rational basis, and remains relevant to be communicated contextually in a pluralistic society.
