Infantile nystagmus syndrome (INS) is a genetically heterogeneous disorder. To date, more than 100 genes have been reported to cause INS and there is significant overlap in phenotypic characteristics. The most common form of X-linked INS is attributed to FRMD7 at Xq26. Recent advances in molecular genetics have facilitated the identification of pathogenic variants of FRMD7 and the investigation for underlying mechanisms of FRMD7-associated INS. This review summarizes genetic and clinical features of FRMD7-associated INS, and introduces updates on the pathogenesis of FRMD7 mutation.

In this study, it was estimated efficiency of GPS/INS photogrammetry by comparison of accuracy and economical efficiency between conventional aerial triangulation and GPS/INS aerial triangulation at the base of large scale digital mapping using GPS/INS aerial survey. The results of aerial triangulation with GPS/INS showed that 40% of working amount was reduced in the process of ground control point survey compared to conventional aerial triangulation. In case of 1/5000 scale aerial triangulation, the results showed that 55% GCP work was reduced in 10 and 20 block size, and 60% GCP work was reduced in 30 block size, under the assumption of keeping the same accuracy.

This paper suggests a GPS/INS navigation computer architecture that can be applied to small satellites. In order to implement a GPS/INS navigation system on a small satellite, the extreme environment in space such as radiation, micro-gravity, vacuum, etc. must be considered. In addition, a real-time processing ability is required for the GPS/INS navigation system since the formation flying of multiple small satellites is the ultimate goal. The developed navigation electronics utilizes a PowerPC-type MPC860T that has space environment heritage, and a pair of Atmega128s that has been implemented in KAUSAT-2 and has completed the space environment verification tests. The navigation algorithm is designed to work in VxWorks environment, ported in MPC860T.

The Canadian public broadcaster CBC had successfully aired a sitcom centered on a Korean immigrant family from 2016 to 2021. The show is based on the play Kim's Convenience written by a Korean-Canadian playwright Ins Choi. This study explores literary features of Kim's Convenience that accounts for its popularity; three elements of the show play crucial roles in maintaining the balance between specificity and universality. First, Choi deploys a Korean immigrant story in the form of comedy. Second, the main plot revolves around an ordinary family with generational strains that ends in reconciliation. Third. the Kims are depicted more as an archetypical family than a stereotypically Asian one. By closely interweaving these elements, Choi induces the audience to find commonalities from the show, and racial specificities of the Kim's family become "spicy" attractions of the play.

Infantile nystagmus syndrome (INS) refers to congenital forms of nystagmus that are present at birth or during infancy. This syndrome may be caused by afferent visual system disorders or abnormal development of the ocular motor system. INS is a genetically heterogeneous disorder for which there are more than 100 causative genes. Since applying clinical tests for the differential diagnosis of INS can be challenging in early infancy and children, genetic testings such as next-generation sequencing are becoming more important for achieving accurate diagnoses. An improved understanding of the molecular mechanisms of INS may also lead to the development of gene-based therapies for INS. These advantages of genetic testing have the potential to change the diagnostic paradigm of patients with INS. However, the diagnostic pathway based on genetic testing still has several limitations in terms of the therapeutic effect and methodology. This review summarizes genetic and clinical features of INS, and discusses the promise and pitfalls of genetic testing in INS.

Real-time Aerial Monitoring System performs the rapid mapping in an emergency situation so that the geoinformation could be constructed in near real time. In this system, the position and attitude information from GPS/INS integration algorithm is used to perform the aerial triangulation(AT) without GCPs. Therefore, if we obtain Exterior Orientation(EO) estimates from AT sequentially, EO are used as the measurements in the Kalman filter. In this study, we simulate the GPS/IMS/Image data for an UAV-based aerial monitoring system and compare the GPS/INS/AT with and without from AT. Comparative analysis showed that result from the GPS/INS/AT with EO update is more accurate than without the update. However, when the vehicle turns, the position error significantly increases which need more analysis in the future.

This paper proposes a local estimation system which combines Cell Divide Algorithm with low-cost GPS/INS fused by Extended Kalman Filter(EKF) for localization of Quad-rotor when it returns to the departure point. In the research, the low-cost GPS and INS are fused by EKF to reduce the local error of low-cost GPS and the accumulative error of INS due to continuous integration of sensor error values. When the Quad-rotor returns to the departure point in the fastest path, a moving path can be known because it moves straight, where Cell Divide Algorithm is used to divide moving route into the cells. Then it determines the closest position of data of GPS/INS system fused by EKF to obtain the improved local data. The proposed system was verified through comparing experimental localization results obtained by using GPS, GPS/INS and GPS/INS with Cell Divide Algorithm respectively.
