DIGITAL READINESS INFLUENCE ON MOBILE ADVERTISING ACCEPTANCE AMONG YOUNG MILLENNIALS
Reza Ashari Nasution,Dwine Fatimah Azzahra,Devi Arnita 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07
Purpose – Research on technology acceptance involves one's psychological aspect, known as technology readiness. Particularly in the digital acceptance context related to mobile advertising, this psychological condition is referred to digital readiness. Nasution, Rusnandi, Qodariah and Arnita (2018) argue that digital readiness is a prominent factor in the adoption of technology and digital applications. They have proven the importance of this digital readiness in their research on digital mastery level in a telecommunication company in Indonesia. The purpose of this paper is to investigate the effect of digital readiness on the acceptance toward mobile advertising among millennials in Bandung, Indonesia. Relevant theories – Mobile advertising is part of digital advertising, as stated by Nasution & Aghniadi (2016), they define mobile advertising as a form of digital advertising that has attentions on engaging a strong communication to audience. This type of advertising adoption is still continuously growing and becoming preferable form of advertising for the Millenials. Researchers developed a model that links the influence of digital readiness to mobile advertising acceptance. In addition to these relationships, the research model they developed from the Technology Acceptance Model also included the influence of perceived usefulness and perceived risk to mobile ads acceptance. Design/methodology/approach – The research model is developed from Technology Acceptance Model (TAM) with a specific attention to assessing whether digital readiness influences the respondents’ perception of usefulness and risk of mobile advertising. The research performs quantitative approach using survey that is formed based on previous literature and conceptual model. Structural equations modelling (SEM) is also conducted to test the constructed model and the proposed hypotheses. Byme (2010) states the significance of the estimated coefficients for the hypothesis relationships which indicate whether the relationship between constructs held true or not. This research will then compare between three models that are differed by range of respondents’ ages. First model will be combined age that is 17-24 years old, second model is 17-20 years old and third model is 21-24 years old. Findings – The results show that digital readiness has a significant influence towards mobile advertising acceptance among Millennials, in which action readiness is more considered than attitudinal readiness in terms of further assessing mobile advertising. In addition, the study also illustrates Millennials’ perception of usefulness and risk of receiving mobile advertising. Younger group (17 – 20 years old) will not be affected much by usefulness of mobile advertising rather than the older group who will consider much about usefulness on accepting mobile advertising. The group also will take risk along with their ability to accept mobile advertising. It contradicts with the older group (21 – 24 years old) who see risk as hindrance in accepting mobile advertising. Research limitations/implications – The area coverage of respondents only included several cities across Java and does not concern about the place of origin of respondents. Besides, this research also possesses an age limit for its respondents that range from 17 to 24 years old to limit the diversity of attitudes, beliefs and perceptions. Originality/value – This study focuses on the concept of Technology Acceptance Model (TAM) in which the digital readiness is applied in the context that has not been conducted in Indonesia. Researchers conducted an empirical study on the effect of digital readiness on mobile advertising that is part of digital technology. The results of this research provide opportunities for digital readiness applications in research on the adoption of other digital technologies. Paper type - Applied research

Hydrogen Peroxide Induces Hyphal Differentiation in Candida albicans
Nasution, Olviyani,Srinivasa, Kavitha,Kim, Minsun,Kim, Yeo-Jung,Kim, Wankee,Jeong, Woojin,Choi, Wonja American Society for Microbiology 2008 EUKARYOTIC CELL Vol.7 No.11
<B>ABSTRACT</B><P>In this study, we demonstrate that hyphal differentiation is induced by the subtoxic concentration of exogenous H2O2 in <I>Candida albicans.</I> This finding is confirmed by the changing intracellular concentration of H2O2. In order to induce the same level of differentiation, low concentrations of exogenous H2O2 are required for the null mutants of the thiol-specific antioxidant and catalase, while higher concentrations are needed for cells treated with ascorbic acid, an antioxidant chemical.</P>

The Meltdown of the Indonesian Economy in 1997-1998 : Causes and Responses
Anwar Nasution 서울대학교 경제연구소 1998 Seoul journal of economics Vol.11 No.4
Indonesia was hit hardest by the recent economic crisis. Overinvestment in non-traded sector and manufacturing industries that required high level of protection was the root cause of the crisis. The weak financial system of Indonesia also exacerbated the crisis. The crisis was aggravated further by the political uncertainty that evolved around the departure of Suharto. The lack of government determination to adopt sound macroeconomic management did not help, either. This paper reviews the banking and currency crisis still unfolding in Indonesia from various angles. For this purpose, it first reviews the recent macroeconomic developments prior to the crisis. Then the paper discusses the banking crisis in detail. An analysis of the policy responses to the crisis is another integral part of the paper.

Purpose – This paper holds a purpose to examine the influence of perceived utility, contextual relevance and lifestyle on the acceptance of mobile advertising among millennials in Indonesia (specifically in Bandung). The three factors represent an extension of the general model of mobile advertising which is largely influenced by the Theory of Reasoned Action (TRA). The factors are proposed to extend the model to include factors at individual (receiver), object (message) and contextual levels. Lifestyle, Perceived Utility, and Contextual Relevance are factors at individual, object and context that are posited to influence the acceptance of mobile advertising in this study. Specifically, the current study is aimed at elaborating the role of those factors in influencing the acceptance of mobile advertising among millennials in Bandung, Indonesia. Relevant theories – mobile marketing definition and scope from various literature, Theory of Reasoned Action (TRA), theory of perceived utility, consumers’ utilization of contextual information in mobile advertising, and the influence of lifestyle – as representation of individual factor – on mobile advertising acceptance are the most relevant theories for the current paper. Design/methodology/approach – The research was conducted by devising a new model that includes acceptance of mobile advertising, attitude toward mobile advertising, subjective norm in relation to mobile advertising, perceived utility of mobile advertising, contextual relevance of message and income (as representation of individual lifestyle). The questionnaires distributed to young adults segment within varsity area. The data is then examined and evaluated through structural equation modelling (SEM) which requires analysis on measurement and path model. Findings – The study resulted in several findings, mostly confirming proposed hypotheses in varying degrees. The results conclude that attitude is of great importance in the acceptance of mobile advertising. Subjective norms and contextual relevance are positively related to attitudes — which lead to acceptance, while both perceived utility and income in negative relations to attitude and acceptance consecutively. Research implications and limitations – This study adds up to the growing amount of related research in various countries. Companies making use of the mobile advertising as part of their promotional strategies should always think of the manner and matter by which the advertisements arrive while serving as benefit for marketers and consumers. A good mobile advertising strategy will put more effort into giving useful information that is appropriate to the context and consumer segments it targeted. This research is conducted on respondents from Indonesian consumers, specifically in the area of Bandung, which may not represent the other segments of users of mobile advertising. In addition, the case covers a convenience sample of consumers that may again impact the representativeness of the research findings. Originality/value – This study provides findings on the effects of contingency factors that have been missing in the previous research on the acceptance of mobile advertising.

Coke combustion kinetics of spent Pt-Sn/Al2O3 catalysts in propane dehydrogenation
Pajri Samsi Nasution,정재원,오경석,고형림 한국화학공학회 2020 Korean Journal of Chemical Engineering Vol.37 No.9
The kinetics of coke combustion was investigated by using a thermogravimetric analyzer (TGA) of coked catalysts which was used for propane dehydrogenation to determine the activation energy. Apart from the Pt/Al2O3 catalyst, four different Pt-Sn/Al2O3 catalysts were prepared by varying the Pt/Sn ratio from 3 : 0.5 to 3 : 3 by weight. The catalytic activity was measured by propane dehydrogenation at 620 o C. The reactant mixture consisting of C3H8 (30 ml/ min) and H2 (30 ml/min) was fed into the reactor for 5 h. A thermogravimetric analyzer in the presence of air was used to determine the amount of coke deposited and calculate the kinetic parameters for coke combustion. Three nonisothermal models (Friedman, Flynn-Wall-Ozawa (FWO), and Kissinger-Akahira-Sunose) were used to determine the activation energy and the best model to fit the experimental data. The FWO model provided the best fit for 3Pt/Al2O3 and 3Pt-0.5Sn/Al2O3. The three models were equivalent for fitting the data for 3Pt-1Sn/Al2O3, 3Pt-2Sn/Al2O3, and 3Pt3Sn/Al2O3. The activation energy increased with increasing Sn addition in the 3Pt/Al2O3 catalyst. Differences in the locations and the qualitative features of the cokes were suggested to interpret the results.

<P>PMA1 encodes a transmembrane polypeptide that functions to pump protons out of the cell. Ectopic PMA1 overexpression in Saccharomyces cerevisiae enhances tolerance to weak acids, reactive oxygen species (ROS) and ethanol, and changes the following physiological properties: better proton efflux, lower membrane permeability, and lessened internal hydrogen peroxide production. The enhanced stress tolerance was dependent on the mitogen-activated protein kinase (MAPK) Hog1 of the high osmolarity glycerol (HOG) pathway, but not the MAPK Slt2 of the cell wall integrity (CWI) pathway; however, a PMA1 overexpression constitutively activated both Hog1 and Slt2. The constitutive Hog1 activation required the MAPK kinase kinase (MAP3K) Ssk2 of the HOG pathway, but not Ste11 and Ssk22, two other MAP3Ks of the same pathway. The constitutive Slt2 activation did not require Rom2 and the membrane sensors of the CWI pathway, whereas Bck1 was indispensable. The PMA1 overexpression activated the stress response element but not the cyclic AMP response element and the Rlm1 transcription factor. PMA1 overexpression may facilitate the construction of industrial strains with simultaneous tolerance to weak acids, ROS, and ethanol.</P>

Purpose: The aim of this study was to conduct a scoping review of knowledge and information delivery modes related to preconception care (PCC) among adolescent girls and women Methods: A scoping review was performed on studies selected from five electronic databases (Cochrane Library, PubMed, Science Direct, CINAHL/EBSCO, and ProQuest), published between 2012 and 2022, with predetermined keywords and criteria. We included English-language research articles available in full text and excluded irrelevant articles.Results: This study included eight articles, comprising seven quantitative studies and one qualitative study conducted among adolescent girls and women. Five were from low- and middle-income countries and three were from high-income countries. The synthesized themes generated from the data were PCC knowledge and PCC information delivery modes and effectiveness. In general, adolescent girls and women were found to have basic PCC knowledge, including risk prevention and management and a healthy lifestyle, although more extensive knowledge was found in higher-income countries than in lower-income countries. The delivery modes of PCC information have grown from individual face-to-face conventional methods, which are used predominantly in lower-income countries, to more effective digital mass media.Conclusion: Globally, many women still have insufficient knowledge regarding PCC, as not all of them receive access to PCC information and support. PCC promotion efforts should be initiated earlier by involving a wider group of reproductive-age women and combining individual, in-group, face-to-face, and electronic delivery modes.
