보현산천문대가 준공되면서, 1.8 m 망원경이 연구자들에게 공개된지 20년이 되었다. 당시 보현산 천문대의 연구자들은 1.8 m 망원경을 도약망원경이라 부르면서, 우리나라 천문학의 비약적인 발전의 토대가 되기를 희망하였다. 보현산천문대 10주년 기념 담양 워크샵에서 BOES의 성과를 발표한 이후 10년 동안, 천문연구원 광학천문기술 그룹에서는 BOES 편광분광기와 IGRINS를 개발 완료하였으며, GMTNIRS의 개념설계와 GCLEF의 기본설계가 진행되었다. 여기에서는 그동안 개발된 고분산 천체분광기 프로젝트의 성과를 정리하고, 앞으로의 계획을 논의한다.

Gene expression and protein levels of serotonin N-acetyltransferase (AA-NAT, EC2.3.1.87) directly control the diurnal production of the melatonin and correlate with enzyme activity. Effects of protein phosphorylation on the AA-NAT activity were investigated in rat pineal glands and COS-7 cells transiently transfected with AA-NAT cDNA.(omitted)

The NISS (Near-infrared Imaging Spectrometer for Star formation history) onboard NEXTSat-1 is the near-infrared instrument onboard NEXTSat-1 which is being developed by KASI. The imaging low-resolution spectroscopic observation in the near-infrared range for nearby galaxies, low background regions, star-forming regions and so on will be performed on orbit. After the System Requirement Review, the optical design is changed from on-axis to the off-axis telescope which has a wide field of view (2 deg. ${\times}$ 2 deg.) as well as the wide wavelength range from 0.95 to $3.8{\mu}m$. The mechanical structure is considered to endure the launching condition as well as the space environment. The design of relay optics is optimized to maintain the uniform optical performance in the required wavelength range. The stray light analysis is being made to evade a light outside a field of view. The dewar is designed to operate the infrared detector at 80K stage. From the thermal analysis, we confirmed that the telescope can be cooled down to around 200K in order to reduce the large amount of thermal noise. Here, we report the current status of the NISS development.

Understanding visit motivation to parks is important when attempting to improve visitor satisfaction and their intentions to revisit and recommend. The objective of this study is to not only examine the impact of visitors' motivations on their satisfaction, but also study the effect of their satisfaction on their behavioral intentions. This objective will be fulfilled using regression models populated with data from the Gyeryongsan National Park (GNP). Onsite surveys were collected during April and May 2017 at the Donghaksa, Gapsa, Cheonjeong, Sinwonsa, Sangsin, and Sutonggol information centers of the GNP (N=224). The results of this study indicate that the visitors' motivations influenced their visit satisfaction, which, in turn, impacted their behavioral intentions. The study's findings will help park managers and policy-makers establish effective park management strategies and enhance visitors' experiences.
