The Local Volume Mapper(LVM) project in the fifth iteration of the Sloan Digital Sky Survey (SDSS-V) will produce large integral-field spectroscopic survey data to understand the physical conditions of the interstellar medium in the Milky Way, the Magellanic Clouds, and other local-volume galaxies. We are developing the LVM Instrument control software. The architecture design of the software follows a hierarchical structure in which the high-level software packages interact with the low-level and mid-level software and hardware components. We adopt the spiral software development model in which the software evolves by iteration of sequential processes, i.e., software requirement analysis, design, code generation, and testing. This spiral model ensures that even after being commissioned, the software can be revised according to new operational requirements. We designed the software by using the Unified Modeling Language, which can visualize functional interactions in structure diagrams. We plan to use the SDSS software framework CLU for the interaction between components, based on the RabbitMQ that implemented the Advanced Message Queuing Protocol (AMQP).

The Local Volume Mapper (LVM), for the Sloan Digital Sky Survey V, consists of four 16 cm telescopes with three fiber spectrographs in the Las Campanas Observatory in Chile. With the fixed telescopes on optical tables, the Alt-Alt mounted siderostats point and guide targets during spectrograph exposures. We are developing the integrated LVM instrument control software. Considering international travel restrictions caused by the COVID-19 pandemic in 2021, we decided to make a simplified version of siderostat to test the LVM telescope control system in Korea. The prototype siderostat consists of two aluminum flat mirrors, optomechanical housing structures made by aluminum profiles, and the Planewave L-350 mount. We designed the optical mirrors and the optomechanical structure of the siderostat. From structural analysis at various pointing cases, we estimated the tilt misalignments of mirrors within 4 arcsec, which would affect the telescope pointing errors.

Purpose - This study quantitatively examines the level of financial inclusion of a microfinance institution in each region and how this is changing recently, and examines the level of financial inclusion by region and various financial characteristic factors related to it. It was empirically verified what kind of significant impact actually has on the institution's major management performance indicators (stability, profitability, efficiency, and public interest). Design/methodology/approach - It was confirmed that the institution's financial inclusion index declined rapidly after 2015 as a whole, although there were some differences by region depending on regional characteristics. However, considering the fact that the number of branches per 100,000 adult population is steadily increasing nationwide, it was found that, contrary to what is known, the simple decrease in the number of branches of the institution was not the main cause. Findings - The analysis results of this study show that the institution's efforts for financial inclusion have a positive impact on profitability, stability, efficiency, and public interest, and that the institution pursues profitability, efficiency, stability, and public interest. showed that some trade-offs exist. In other words, overall, it was analyzed that profitability of the institution has a positive effect on efficiency, and efficiency has a positive effect on stability and public interest. Research implications or Originality - Since the institution's efforts to improve its profitability do not have a negative impact on its stability and public interest, it is judged that it is important to take a strategic stance, so excessive loan supply that exceeds the scope of the institution's own control needs to be avoided as much as possible. More detailed financial supply strategies and business management capabilities that enhance the asset soundness and management efficiency of safes need to be demonstrated.

As the educational function of Confucian school in the late Chosun dynasty had been declined, the other educational institution called YANGSAJAE was established. The founders of the institution was either local authorities or local Confucianists. Otherwise the institution was established by the cooperation of both local authorities and local Confucianists. YANGSAJAE began to be established from the 16th century. Most of them was founded in 1700s. In 1800s, it was not so difficult to see YANGSAJAE in many towns in Young nam and Honam provinces. The institution was located in separate places at the early stage of foundation. But since the middle of 1700s, the institution was located in or near the Confucian school. As a consequence, this influenced the location of Confucian schools in the late Chosun dynasty. In Youngnam province, the institution was mainly located near the Confucian school or in a separate place. On the contrary, most of the institution were constructed within Confucian school in Honam province. There were two types of the flat composition: one is based on hall and the other is based on room. The hall type, which had a hall in the middle and rooms in both sides, was general. The hall type usually had a size of 4-kan in width and 1.5-kan in length. The half-hipped roof was the general type and intimately related to the roof of Myung-Ryun Dang of local Confucian School.

The senior citizens population and welfare institution for them is increased. The senior citizens in welfare institution spend a long time in indoor and their health is greatly affected by the indoor environment. Therefore, the indoor environment of senior citizens welfare institution is very important. This study presents some primary data based on the survey of architectural conditions and the measurements of indoor air quality for senior citizens welfare institution. According to characteristic of region, six of Incheon Area's senior citizens public welfare institution are selected. An investigation and analysis into architectural conditions and indoor air quality including temperature, humidity, CO, $CO_2$, PM10, HCHO, TVOC are conducted. The temperature, humidity and $CO_2$ concentration is some high. The HCHO concentration is very high. The indoor flooring and furniture materials highly impacts on the concentration of HCHO and TVOC.

This study was conducted to find out the management status of radioisotopes and radioactive waste products in Korean medical institutions during the period of three years from 1991 to 1993. The results are summarized as follows : 1. The rate of medical institution to the institutions making use of radioisotopes was decreased every year, for example, 18.11 % in the year 1991, 17.86 % in the year 1992 and 15.87 % in the year 1993. 2. The use of domestic made radioisotopes in the medical institution was increased every year, for instance, 89.68 % in the year 1991, 94.21 % in the year 1992 and 99.79 % in the year 1993. 3. 91.01 % of the half life of isotopes used in the medical Institution were two month below. 4. The rate of radioactive waste products in the medical institution to all radioactive waste products was increased every year, for example, 54.44 % in the year 1991, 75.36 % in 1992 and 78.49 % in the year 1993. 5. The rate of inflammable waste products from medical institution was 76.47 % of all inflammable waste products, and 73.99 % of whole waste products was from the medical Institution.
