Korea Pathfinder Lunar Orbiter (KPLO) is South Korea’s first space exploration mission, developed by the Korea Aerospace Research Institute. It aims to develop technologies for lunar exploration, explore lunar science, and test new technologies. KPLO was launched on August 5, 2022, by a Falcon-9 launch vehicle from cape canaveral space force station (CCSFS) in the United States and placed on a ballistic lunar transfer (BLT) trajectory. A total of four trajectory correction maneuvers were performed during the approximately 4.5-month trans-lunar cruise phase to reach the Moon. Starting with the first lunar orbit insertion (LOI) maneuver on December 16, the spacecraft performed a total of three maneuvers before arriving at the lunar mission orbit, at an altitude of 100 kilometers, on December 27, 2022. After entering lunar orbit, the commissioning phase validated the operation of the mission mode, in which the payload is oriented toward the center of the Moon. After completing about one month of commissioning, normal mission operations began, and each payload successfully performed its planned mission. All of the spacecraft operations that KPLO performs from launch to normal operations were designed through the system operations design process. This includes operations that are automatically initiated post-separation from the launch vehicle, as well as those in lunar transfer orbit and lunar mission orbit. Key operational procedures such as the spacecraft’s initial checkout, trajectory correction maneuvers, LOI, and commissioning were developed during the early operation preparation phase. These procedures were executed effectively during both the early and normal operation phases. The successful execution of these operations confirms the robust verification of the system operation.

There are various methods that have been recommended for seismic performance of a building structure such as Displacement coefficient Method, Capacity Spectrum Method, Direct Capacity Spectrum Method, Modal Pushover Analysis etc. Evaluation of seismic performance based on the these methods generally used for estimation of seismic deformation capacity and demand of a building structure in the performance based earthquake engineering. In this study, a new improved method of seismic performance evaluation for a high-rise steel moment frame building, which take into account the higher mode effects and accurate inelastic seismic responses, is presented. And the various approaches including the proposed method are carried out for estimating deformation capacity for a high-rise building subjected to various earthquake ground motions and compared with responses such as plastic hinge formations, interstory drifts and energy dissipation etc. of inelastic time history analysis.

A two-layer, solutally-stratified system with a single interface in a square rectangle is simulated. As noted in previous studies, a unicell flow pattern appears in case of relatively lower buoyancy ratio, while global fluid motion does as layered flow pattern with two convective layers. The averaged Nusselt number develops as the same tendency with pure natural convection and convective effect retards as buoyancy ratio increases. There is no effect with Lewis number, but for N≥0.7 the convective effect is much more delayed in Le=10 than in Le=100 and 300.

The effects of Paeryungsan and Bojungchiseubtang on rats with nephrosis induced by a single intravenous injection of puromycin aminonucleoside(PAN), 2.5mg/100g of body weight were evaluated in the present study. The effects of Paeryungsan and Bojungchiseubtang on PAN nephrosis were evaluated by measuring ①the concentrations of albumin, total protein, total lipid, cholesterol, triglyceride, creatinine, blood urea nitrogen and uric acid in the serum, ②the amount of volume, protein, glucose and creatinine of the 24hours urine ③the concentration of blood in the urine, intake water, and by observing the changes of microscopic findings of kidney. The results are summerized as follows; 1. In the control group, the concentrations of cholesterol, creatinine, blood urea nitrogen in the serum, the amount of protein and glucose of 24 hours urine, creatinine of 24 hours urine and 24 hours urine volume on the 22th day were significantly increased. On the other hand, the concentration of albumin in the serum, the amount of creatinine of 24 hours urine on the 8th day, the volume of 24 hours urine and the intake water on the 8th, 15th day were decreased significantly. Electron microscopic findings were the segmental obliteration of the foot processes, swelling and villous transformations of the visceral epithelial cells and partial increase of the mesangial matrix. 2. In Paeryungsan group, the decrease of albumin in the serum and intake water were inhibited significantly. But the increase of the concentrations of cholesterol and blood urea nitrogen in the serum were inhibited significantly. And the amount of creatinine of 24 hours urine was increased significantly. There was no significant difference between Paeryungsan group and the control group in electron microscopic findings. 3. In Bojungchiseubtang group, the decrease of albumin in the serum and intake water were inhibited significantly. But the increase of the concentrations of cholesterol, total lipid, creatinine, blood urea nitrogen in the serum and the amount of protein in the 24 hours urine were inhibited significantly. The concentration of protein in the serum was increased significantly. There was no significant difference between Bojungchiseubtang group and the control group in electron microscopic findings. To conclude, PAN nephrosis was induced by a single intravenous injection of PAN 2.5mg/100g of body weight on rats. It can be inferred that Paeryungsan group has the effects of improving hypoalbuminemia in nephrotic syndrome and relieving azotemia when nephrotic syndrome is accompanied by the acute renal failure. It can be inferred that Bojungchiseubtang may improve proteinuria, hypoalbuminenia, hyperlipidemia in nephrotic syndrome. But there was no significant difference between Paeryungsan and the control group, between Bojungchiseubtang group and the control group in electron microscopic findings. So I hope that there will be further studies on the effect on the alterations of glomerular polyanion sites, and on the functioning mechanism of Paeryungsan and Bojungchiseubtang in the future.

Attempts were made to investigate the levels of chemical components and detoxification of the salted puffer overies, Fugu xanthopterus, "Ggachibog" and Fugu rubripes rubripes, "Chambog", processing of solid salt mixtures containing sodium bicarbonate, during storage period. Fresh ovaries of the puffers were divided into three portions, sprinkled with a solid salt mixture containing 0,1 or 2% NaHCO₃, and were stored at room temperature for 12 weeks. The samples were examined at each step and assayed for pH, VBN, amino-N, toxicity and thin- layer chromatogram pattern. The results were summarized as follows: The values of pH were appeared to be different with the added amount of siodium bicarbonate and the values of pH were over 7.0 in a salt mixture containing 2% NaHCO₃. The change of VBN value was also revealed about 85mg/100g in A division and 90-100mg/100g in both B and C, respectively, in the salted ovary of puffer "Ggachibog" from 8 weeks. In case of salted product from the "Chamboh" ovary, it had slightly lower value than that of "Ggachibog" ovary. Also, the value of amino-N was increased until 4-6 weeks and was slowly down after the weeks in all samples. All salted products were found to lose most of the toxicity during storage period when the salt containing NaHcO₃was used for sprinkling. In the case of raw ovaries being weak toxicity below 5.0 MU/g or 24.1 MU/g, the toxicity of salted product was dropped near the level to be edible. Therefore there was significant detoxification of the puffer ovaries by the salt mixture containing sodium bicarbonate. Finally, the toxins isolated from each raw puffer ovary were detected to be TTX-related components by thin-layer chromatogrphy.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.
