Based upon the previous heritage in the complete development of the infrared imaging spectrometer, NISS (Near-infrared Imaging Spectrometer for Star formation history) onboard NEXTSat-1, we are participating in the NASA MIDEX mission (PI Institute: Caltech), the all-sky infrared spectro-photometric surveyor SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer). The SPHEREx will provide us the first all-sky infrared spectro-photometric data set to probe the origin of our Universe, to explore the origin and evolution of galaxies, and to explore whether planets around other stars could harbor life. After the SPEHREx have passed the PDR (Preliminary Design Review) on this September, the fabrication of flight hardware will be started soon. As an international partner, KASI takes part in the hardware development, the operation and the science for the SPHEREx. Here, we report the status of the SPHEREx project and the progress in the Korean participation.

This paper tries to show the formation of 'Kyungpook School' that is a nickname given to mathematicians of Kyungpook National University (KNU). In the early period, the role of professor Park Jung-gi was the most important drive to set the research tradition. He made Korea's first english journal in mathematics, Kyungpook Mathematical Journal KMJ which became a cornerstone for students to join the international academic community. Professor Ki U-hang published the most amount of papers in Korea in 1970s and became a role model for young scholars. In this background, KNU's Topology and Geometry Research Center at KNU was chosen as the only Science Research Center in mathematics in 1989, and KNU's mathematicians could get a long-period support for capable mathematics researchers' community.

In this paper, we investigate a relation between the history of western logic and religion. Logic, as distinct from theology, began in Greece in the sixth century B. C. After running its course in antiquity, it was again submerged by theology as Christianity rose and Rome fell. Its second great period, from the eleventh to the fourteenth centuries, was dominated by the Catholic church, except for a few great rebels, such as the Emperor Frederick II(1195-1250). This period was brought to an end by the confusion that culminated in the Reformation. The third period, from the seventeenth century to the present day is dominated by science; traditional religious beliefs remain important but are felt to need justification, and are modified wherever science seems to make this imperative.

The egg development and early life history of Korean spotted sleeper, Odontobutis interrupta which is Korean endemic species from Sora-choen was investigated. The Korean spotted sleeper were caught at Sora-myeon, Yeosu-si, Jeollanamdo, from Korea at May in 2014. The fertilized eggs were $4.23{\pm}0.05mm$ in long diameter and had oil globules. Hatching time of the embryo began about 442 hr 14 min after fertilization under water temperature of $19.5^{\circ}C$. The newly hatched larvae were $4.27{\pm}0.35mm$ in total length and their anus were not yet opened. 3 days after hatching postlarvae was measured $6.20{\pm}0.11mm$ in total length. 10 days after hatching postlarvae was measured $6.69{\pm}0.14mm$ in total length.

Arrivals of Hilbert and Minkowski at $G\ddot{o}ttingen$ put mathematical science there in full flourish. They further extended its strong mathematical tradition of Gauss and Riemann. Though Riemann envisioned Finsler metric and gave an example of it in his inaugural lecture of 1854, Finsler geometry was officially named after Minkowski's academic grandson Finsler. His tool to generalize Riemannian geometry was the calculus of variations of which his advisor $Carath\acute{e}odory$ was a master. Another $G\ddot{o}ttingen$ graduate Busemann regraded Finsler geometry as a special case of geometry of metric spaces. He was a student of Courant who was a student of Hilbert. These figures all at $G\ddot{o}ttingen$ created and developed Finsler geometry in its early stages. In this paper, we investigate history of works on Finsler geometry contributed by these frontiers.

Uirimchalyo (醫林撮要), one of the most important books in the history of Korean Medicine (KM), has not been researched within the framework provided by Yi'an (醫案), an East Asian tradition of describing clinical encounters with the therapies employed. In modern times, this practice of Yi'an might be similar to the outline of a singular "case study". The authors designed the study to analyze the basic information of Yi'an within the Uirimchalyo and to contribute to the foundations of employing Yi'an in Korean Medicine. A standard was established, and the 123 Yi'ans were extracted, most of which were taken from the chapter, Historic Doctors (歷代醫學姓氏). Using this information and in comparison with other medical books such as Euibangyoochui (醫方類聚), the authors learned that the Yi'ans from the Jinyuansidajia (金元四大家), including those of four eminent clinicians in Jin (金) and Yuan (元) Dynasty, are excluded from Uirimchalyo. The authors identified that Yi'ans from other medical books, are cited in the Uirimchalyo but with different format, not with the traditionally understood form of Yi'an. This study of the Uirimchalyo Yi'an resulted in three important understandings of Yi'an. First, the mere number of Uirimchalyo Yi'an is meaningful in that it raised the genre of Yi'an to the a level not previously recognized. Second, in the history of Korean Medicine, Yi'an is first systematized in the Uirimchalyo at the chapter of Historic Doctors. Third, Uirimchalyo raised the concept of usefulness of Yi'an, to the practice of Korean Medicine.

The purpose of this study is to survey the circumstances of sniping warfare and to prove the importance of usage of snipers. The research method was referred to the history of foreign warfares and autobiographies, articles, and testimonies of snipers. Also, various news reports were also studied to collect information. The content of this study investigates the circumstances of sniping combat scenes from its first appearance in the world's major warfares to contemporary ones. Also, the research contains the history of weapons, ammunition, rifles, and the principle of rifle shooting including ballistics. We hope this study provides ROK Army and government agencies the foundation of sniping and thereby improving the effectiveness of correspondence to international conflicts and terrorism.

In this study, we examine Maeng Hwa-seop's academic activities, focusing on articles published in Uirim, JKM (Journal of Korean Medicine), and other branch journals which were affiliated with the Society of Korean Medicine. The present study charts and summarizes the papers published in the above journals. By organizing Maeng Hwa-seop's papers and making tables, we find that his research can be divided into four categories: symptoms and diseases, prescriptions, academic presentations, and translations of medical literatures. Based on this study, we hope that further researches about the academic activities of Maeng Hwa-seop can be conducted in the future.

Glyceraldehyde 3-phosphate dehydrogenase(GAPDH) is a key enzyme for carbohydrate metabolism in most living organisms. Recent reports and our own searches of teleost species in publicly available genomic databases have identified at least two distinct GAPDH genes in a given species. The two GAPDH genes are located on the same chromosome in teleosts, whereas they are located on the different chromosomes in mammals. Thus, we reconstructed a phylogenetic tree to better understand the evolutionary history of the GAPDH genes in the vertebrate lineage. Our phylogenetic analysis revealed unambiguously that the two GAPDH genes of teleosts are phylogenetically closely affiliated to one of the cytosolic GAPDH and spermatogenic GAPDH-S of mammals. This indicates that the two paralogous GAPDH genes shared a common ancestor and subsequently underwent a gene duplication event during early vertebrate evolution. However, GAPDH-S of teleosts showed significant differences in the polypeptide residues and tissue distribution of its mRNA transcripts from that of mammals, implying they have undergone a different history of functionalization.

Paper folding is a versatile tool that can be used not only as a mathematical model for analyzing the geometric properties of plane and spatial figures but also as a visual method for finding the real roots of polynomial equations. The historical evolution of origami's geometric and algebraic techniques has led to the discovery of definitions and properties that can enhance one's cognitive understanding of mathematical concepts and generate mathematical interest and motivation on an emotional level. This paper aims to examine the history of origami geometry, the utilization of origami for solving polynomial equations, and the process of determining the real roots of quadratic, cubic, and quartic equations through origami techniques.
