Background: The COVID-19 pandemic, which has spread very quickly, has created crises in all aspects of life around the world. The administration of the COVID-19 heterologous vaccine in Indonesia is prioritized for high-risk groups, one of which is health workers. This study aimed to determine the comparison of quantitative IgG antibody levels for SARS CoV2 between health workers with and without a history of being infected with COVID-19 after heterology vaccination at Dr. Mohammad Hoesin General Hospital, Palembang, Indonesia.
Methods: This study was a cross-sectional analytic observational study. A total of 64 subjects participated in this study. Data analysis was carried out with the help of SPSS software in univariate and bivariate.
Results: SARS-CoV2 IgG antibody levels with and without a history of being infected with COVID-19 after heterologous vaccination did not find a significant difference in IgG levels between the two groups. However, the quantitative IgG levels of SARS-CoV2 in the infected history group were greater, namely 4834.25 AU/mL, compared to no history of COVID-19 infection of 3833.35 AU/mL
Conclusion: There is a difference in the average SARS-CoV 2 IgG between subjects with a history of being infected with COVID-19 and without a history of COVID-19 at Dr. Mohammad Hoesin General Hospital, Palembang, Indonesia, although statistically, it is not significantly different.

Authors: Nakiwala Margaret , Mukiibi Stephen , Kigundu Amin Tamale 
Published: January 2023

This paper summarises the housing challenges that stem from the increasing population growth in Uganda by reviewing the literature. The housing deficit is the problem that the goals set in the National Development Plan (NDP III) determine to alleviate. In her NDP III, Housing Finance Bank strategised to offer affordable mortgages to Ugandan citizens. It is clearly stated in the NDP III that the problem of housing financing is left to the individuals as the central government cannot set up housing for all its citizens. The theories that guide the use of mortgage financing include the Lien, Title, Intermediate, and Lifestyle theories. This argument is presented in a systematic literature review of studies about the issues around mortgage financing in different parts of the world—specifically, Access. Established Knowledge, Attitudes and Challenges of accessing mortgage financing were issues of concern that needed researching.
Moreover, the literature confirmed that the biggest challenge that housing developers endure to access mortgage financing is the high-interest rates, especially in developing countries. Various economies have people with different knowledge about Mortgage Financing. Uganda is the case study that aimed at increasing urban housing accessibility by citizens of the country. The research method applied in this paper is purely qualitative research that analyses the opinions of different academic scholars in mortgage financing. However, this paper argues that financial institutions' eligibility terms significantly limit Access to Urban Housing through mortgage financing. The set terms need to reviewing to suit the informal setting of developing countries like Uganda. The recommendation from the study is the adoption of a central tool to oversee the set eligibility terms on mortgages.

Assessment of Fructosamine 3-kinase in Type 2 Diabetic Patients and Its Relation to Some Biochemical Variables
Authors: Abdulrahman Tamara , Mohammed Rafad 
Published: January 2023

It took over 30 years for first description of the synthesis of fructosamines and this was conducted through non-enzymatic protein-glucose reactions (also known as glycation). Fructosamines in mammalian cells has not been known until recently. It transforms spontaneously into advanced glycation end products. The discovery of fructosamine 3-kinase, which is a novel enzyme, in human reveals the existence of a previously unknown intracellular metabolism of these substances. Protein-bound fructosamines are phosphorylated by fructosamine 3-kinase with high affinity on a third carbon atom of the deoxyfructose moiety and this results in fructosamine 3-phosphates. These later substances are unstable and spontaneously break down into inorganic phosphate and 3-deoxyglucosone, regenerating the unglycated amine in the process. The fact that many prokaryotic and eukaryotic genomes contain proteins connected to fructosamine 3-kinase shows that this 'deglycation' process is not exclusive to mammals. The current study aims at determining the normal values of fructoseamine 3-kinase enzyme in the control group as well as in the group of patients with type II diabetes (the experimental group). The relationship of enzyme activity with some biochemical variables was also studied in patients with type 2 diabetes, due to the association of these variables with high blood sugar, as shown by previous studies. The Research dealt with the investigation of Fructosamine 3-Kinase activity and some biochemical variables for (136) Type 2 diabetes patients. The results indicated that there was a significant increase in Fructosamine 3-Kinase activity in type 2 diabetes patients (253 ng/l) in comparison to the control group. The normal value of enzyme in the control group was (181ng/l) and the activity of the enzyme in control group individuals was not affected by age and sex. The research also showed a significant decrease in the level of iron, zinc, chromium and sodium as well as a significant increase in the potassium level in patients with type 2 diabetes compared to the control group individuals. Additionally, the research predicted that there is a significant decrease in the levels of vitamins C and E. Also, it was shown that there was a significant increase in malondialdehyde level and a myeloperoxidase activity in type 2 diabetes patients. Activity of FN3K increased in type 2 diabetes compared to the control group individuals. It was noted that the activity of FN3K in the control group was not affected by age or sex.
Heating Effects of Supra-arcade Downflows on Plasma above Solar Flare Arcades
Authors: Xie Xiaoyan , Reeves Katharine K. 
Published: January 2023

Abstract
We deliberately select three flares to investigate heating effects of supra-arcade downflows (SADs) on the surrounding fan plasma. Prior work found in one flare that the plasma around most SADs tends to heat up or stay the same temperature, accompanied by discernible signatures of the adiabatic heating due to plasma compression as well as viscous heating due to viscous motions of plasma. We extend this work to more flares and find that the heating effects of the SADs are also present in these events. The adiabatic heating is dominant over the viscous heating in each event. The adiabatic heating in the two M1.3 flares, being on the order of about 0.02–0.18 MK s−1, is fairly comparable. In the more energetic X1.7 flare, the adiabatic heating is on the order of 0.02–0.3 MK s−1, where we observe a more pronounced temperature increase during which dozens of SADs descend through the fan. As SADs constantly contribute to the heating of the surrounding fan plasma, the areas where SADs travel through tend to cool much slower than the areas without SADs, and the plasma of higher temperature ends up concentrating in areas where SADs frequently travel through. We also find that the cooling rate of areas without SADs is ∼1000 K s−1, much slower than would be expected from normal conductive cooling. Instead, the cooling rate can be interpreted nicely by a process where conductive cooling is suppressed by turbulence.

Abstract
We conducted an optical monitoring survey of the Sagittarius dwarf irregular galaxy (SagDIG) during the period of 2016 June–2017 October, using the 2.5 m Isaac Newton Telescopeat La Palama. Our goal was to identify long-period variable stars (LPVs), namely, asymptotic giant branch stars (AGBs) and red supergiant stars, to obtain the star formation history of isolated, metal-poor SagDIG. For our purpose, we used a method that relies on evaluating the relation between luminosity and the birth mass of these most evolved stars. We found 27 LPV candidates within 2 half-light radii of SagDIG. 10 LPV candidates were in common with previous studies, including one extreme-AGB (x-AGB). By adopting the metallicity Z = 0.0002 for older populations and Z = 0.0004 for younger ages, we estimated that the star formation rate changes from 0.0005 ± 0.0002 M
⊙ yr−1 kpc−2 (13 Gyr ago) to 0.0021 ± 0.0010 M
⊙ yr−1 kpc−2 (0.06 Gyr ago). Like many dwarf irregular galaxies, SagDIG has had continuous star formation activity across its lifetime, though with different rates, and experiences an enhancement of star formation since z ≃ 1. We also evaluated the total stellar mass within 2 half-light radii of SagDIG for three choices of metallicities. For metallicity Z = 0.0002 and 0.0004, we estimated the stellar mass M*
= (5.4 ± 2.3) × 106 and (3.0 ± 1.3) × 106
M
⊙, respectively. Additionally, we determined a distance modulus of μ = 25.27 ± 0.05 mag, using the tip of the red giant branch.
Prompt Enhancements of Radiation Belt Electrons over a Wide Energy Range Based on Phase Space Density Variations: A Detailed Case Study
Authors: Wang Xiaoyu , Cao Xing , Gu Xudong , Ni Binbin , Ma Xin , Luo Taorong , Guo Deyu 
Published: January 2023

Abstract
Based on Van Allen Probes observations, we report a prompt enhancement event of radiation belt electrons over a wide energy range from tens of keV to multiple meV spanning 2013 January 13–15. During this period, we also observe prolonged moderate substorm activities and intense whistler-mode chorus emissions. To differentiate the underlying mechanisms responsible for this prompt electron enhancement process, we investigate in detail the evolution of electron phase space densities (PSDs) for various values of the first and second adiabatic invariants (μ and K). The results show that tens to hundreds of keV electrons rapidly penetrated to L* < 4 during the substorm period, with the corresponding PSDs increasing by more than 3 orders of magnitude within about 1 day. Comparatively, the PSD enhancements of higher energy electrons are less significant and shift to higher L*. We find that the fast acceleration of hundreds of keV seed electrons to multi-meV electrons may be reasonably attributed to interactions with the concurrent chorus waves. Specifically, the electron PSD increases for μ≥ 300 MeV G−1 become less pronounced as K increases, consistent with the pitch angle dependence of chorus-induced electron energy diffusion at high energies. Our results therefore provide clear observational evidence for the combined effect of substorm-induced injection and chorus wave scattering on the prompt enhancements of radiation belt electrons over a wide energy range within a couple of days.

Abstract
We analyzed 20 s cadence Transiting Exoplanet Survey Satellite time-series photometry of the exoplanet host star HR 8799 collected in Sector 56. The amplitude spectrum shows Gamma Doradus (γ Dor) pulsations consistent with previous space-based photometry from MOST. Assuming that HR 8799 is a representative of γ Dor stars in the Kepler sample, the dominant dipole mode at 1.98 cycles day−1 implies a core rotation period of ∼0.7 day, which combined with

i

and stellar radius measurements would result in a preliminary stellar inclination of ∼28° assuming rigid rotation. We find no significant residual photometric variation after removing the pulsation signal aside from a ∼9 days trend that is likely a systematic effect or an artifact from performing aggressive frequency subtraction in the presence of red noise.
Expériences quotidiennes et visions du futur sur l’ancienne frontière interallemande
Authors: Hirschhausen Béatrice von , Verdalle Laure de 
Published: January 2023

Cet article présente les premiers résultats d’une enquête conduite dans deux villages situés de part et d’autre de l’ancienne frontière interallemande, entre Thuringe et Bavière, en « revisitant » le terrain ethnographique conduit par Valentine Meunier dans les années 1990. Trente ans après la réunification, les résultats électoraux des dernières années et les sociabilités locales signalent la persistance d’une « frontière fantôme » sur le tracé de l’ancien Mur, en dépit de l’intensité des circulations quotidiennes et des relations de travail. Pour en éclairer les raisons, nous interrogeons la présence de l’ancienne frontière dans les discours ordinaires ; nous examinons les mobilisations de l’idée de « communauté » (Gemeinschaft) dans les pratiques et les discours de nos enquêté·e·s ; nous interrogeons les rapports au futur déclinés de façon très contrastée selon les niveaux territoriaux.
30 ans de politique familiale en Allemagne : vers la fin de la fracture entre Est et Ouest ?
Authors: Salles Anne 
Published: January 2023

L’effondrement sans précédent des naissances dans l’est de l’Allemagne après l’unification a soulevé la question du rôle joué par l’extension de la politique familiale ouest-allemande à l’ensemble du pays, tant celle-ci ne répondait pas aux attentes des habitants de l’ancienne RDA. Si le niveau de fécondité remonte progressivement à l’Est pour s’établir finalement au-dessus du niveau de l’Ouest à partir de 2008, on observe précisément une inflexion dans la politique familiale allemande avec la mise en place de réformes qui ne sont pas sans rappeler certaines mesures de la RDA. Pour autant, le rapprochement qu’on observe entre les deux parties de l’Allemagne dans les choix familiaux et les décisions de fécondité demeure partiel et le sujet indubitablement sensible. Si l’impact des réformes de politique familiale sur certains choix familiaux ne fait guère de doute, comme la progression du travail à temps partiel chez les mères à l’Est ou le report des naissances, il n’en demeure pas moins limité dans d’autres cas, comme en atteste l’attachement des Allemandes de l’Est au travail à temps plein, ce qui s’explique notamment par le caractère limité des réformes, par un certain décalage entre l’orientation des politiques familiales et les modèles familiaux à l’Est et par le contexte économique.
La politique étrangère de l’Allemagne unifiée. Entre continuités et ruptures
Authors: Marcowitz Reiner 
Published: January 2023

Le discours de « changement d’époque » du chancelier fédéral Olaf Scholz le 27 février 2022 au Bundestag allemand face à l’attaque russe contre l’Ukraine et son annonce d’un engagement militaire accru de la République fédérale d’Allemagne au sein de l’Alliance occidentale rompt avec toutes les traditions ancestrales du pays en matière de politique étrangère et de sécurité. Depuis la création de l’État ouest-allemand, tous les gouvernements allemands ont en effet pratiqué une politique de retenue militaire maximale, d’autant plus que cela permettait de tirer les bonnes leçons des erreurs du passé, mais aussi de tenir compte de la situation géographique et politique particulière et de servir les intérêts économiques de la République fédérale d’Allemagne. Jusqu’à présent, l’unification allemande n’a pas changé grand-chose à cette situation, à la grande déception des alliés du pays : si l’Allemagne a toujours joué un rôle diplomatique important sur la scène internationale, la participation à des opérations militaires comme celles menées dans les Balkans dans la seconde moitié des années 1990 ou en Afghanistan après les attentats du 11 septembre 2001 sont restées des exceptions. On peut donc se demander si le discours du chancelier Scholz marque effectivement le début d’une nouvelle culture en matière de politique étrangère et de sécurité en République fédérale d’Allemagne ou si, à l’instar d’autres débats de ces dernières années, il s’essoufflera à cause de la persistance du rôle traditionnel de l’Allemagne en tant que « puissance civile ».
