To investigate alleviation effects of salt stress by low dose gamma-irradiation on seedling growth of rice (Oryza shrive L), in plants of two rice cultivars (Ilpumbyeo and Gancheokbyeo), seeds were irradiated with the different doses $(0{\sim}32\;Gy)$ of gamma-ray by irradiator ($^{60}Co$, ca.150 TBq of capacity, AECL). The salt stress caused a remarkable decrease of seedling growth, particularly for dry weight. In addition, relative growth rate was decreased over 50% by the salt stress. However, the salt stress-induced inhibition of growth was alleviated by gamma-irradiation. Especially, the relative growth rate of shoot showed the reduction effect over 30% at 4 Gy-irradiated groups as compared with that of control. Also, electrolyte leakage and relative water content were damaged, respectively 4 times and 30% by the salt stress but the damages were alleviated by the gamma-irradiation. These alleviation effects were observed similarly in both the cultivars tested. These results suggest that the low dose gamma-irradiation may have a better protection or the salt stress.

Purpose: This study was to present home-care cases of gangrene sores or prevalent diseases using fake energy salt (FES) water containing energy. Methods: The health functional foods used for disease management were FES Water. Each product was Myeongil Leaf powder, dried yeast, propolis, fermented organic calcium, and royal jelly. Changes were investigated after taking this food. Some of them were combined with hospital treatment, and most of them were experienced by patients at home while managing the affected area. Results: One patient with high fever swine flu, who was treated in a hospital, had a fever dropping to the normal range in 2 hours, and one patient with a leg fracture healed in about six weeks, and one patient had bone adhesion in 2 weeks. Patients with rhinitis recovered after taking FES, and the intraocular pressure of patients with damaged retinopathy fell from 40 mmHg to 20 mmHg after taking FES. One patient with postpartum sequelae was said to have improved their aching limbs four days, and a Covid-19 confirmed patient admitted to the hospital was discharged ten days after starting taking FES during treatment. The size of the gangrene sores in 19 subjects initially ranged from 1 to 7 cm. Most of them were alleviated or healed by continuing to manage them at home with health functional food intake and FES for two weeks to a year. Conclusions: The above results are personal experiences and health functions, such as fake energy salts. It was possible to recognize that food was helpful for health promotion, but no final medical diagnosis was made.

For the removal of cesium (Cs) from high radioactive/high salt-laden liquid waste, this study synthesized a highly efficient composite adsorbent (potassium cobalt ferrocyanide (PCFC)-loaded chabazite (CHA)) and evaluated its applicability. The composite adsorbent used CHA, which could accommodate Cs as well as other molecules, as a supporting material and was synthesized by immobilizing the PCFC in the pores of CHA through stepwise impregnation/precipitation with $CoCl_2$ and $K_4Fe(CN)_6$ solutions. When CHA, with average particle size of more than $10{\mu}m$, is used in synthesizing the composite adsorbent, the PCFC particles were immobilized in a stable form. Also, the physical stability of the composite adsorbent was improved by optimizing the washing methodology to increase the purity of the composite adsorbent during the synthesis. The composite adsorbent obtained from the optimal synthesis showed a high adsorption rate of Cs in both fresh water (salt-free condition) and seawater (high-salt condition), and had a relatively high value of distribution coefficient (larger than $10^4mL{\cdot}g^{-1}$) regardless of the salt concentration. Therefore, the composite adsorbent synthesized in this study is an optimized material considering both the high selectivity of PCFC on Cs and the physical stability of CHA. It is proved that this composite adsorbent can remove rapidly Cs contained in high radioactive/high salt-laden liquid waste with high efficiency.

Gas hydrate (GH) process is a new desalination technology, where GH is a non- stoichiometric crystalline inclusion compounds formed by water and a number of gas molecules. Seawater GH is produced in a low temperature and a high pressure condition and they are separated from the concentrated seawater. The drawback of the GH process so far is that salt contents contained in its product does not meet the fresh water quality standard. This means that the GH process is not a standalone process for seawater desalination and it needs the help of other desalting process like reverse osmosis (RO). The objective of this study is to investigate the effect of GH process on energy saving for RO process in seawater desalination. The GH product water quality data, which were obtained from a literature, were used as input data for RO process simulation. The simulation results show that the energy saving effect by the GH process is in a range of 68 % to 81 %, which increases as the salt removal efficiency of the GH process increases. Boron (B) and total dissolved solids (TDS) concentrations of the final product of the hybrid process of GH and RO were also investigated through the RO process simulation to find relavant salt rejection efficiency of the GH process. In conclusion, the salt rejection efficiency of the GH process should exceed at least 78% in order to meet the product water quality standards and to increase the energy saving effect.

The performance of Li-B alloy as anode for molten salt electrolysis was firstly investigated. The crystalline phase of the prepared Li-B alloy was identified as $Li_7B_6$. The potential profile of Li-B alloy anode was monitored during the electrodeposition of $Nd^{3+}$ onto an LCC (liquid cadmium cathode) in molten LiCl-KCl salt at $500^{\circ}C$. The potential of Li-B alloy was increased from -2.0 V to -1.4 V vs. Ag/AgCl by increasing the applied current from 10 to $50mA{\cdot}cm^{-2}$. It was found that not only the anodic dissolution of Li to $Li^+$ but also the dissolution of the atomic lithium ($Li^0$) into the LiCl-KCl eutectic salt was observed, following the concomitant reduction of $Nd^{3+}$ by the $Li^0$ in Li-B alloy. It was expected that the direct reduction could be restrained by maintaining the anode potential higher that the deposition potential of neodymium.

The decay heat of Cs and Sr contained in a LiCl waste salt, generated from an electrolytic reduction process in pyroprocessing of spent nuclear fuel, has been calculated. The calculation has been carried out under some assumptions that most of the LiCl waste is purified and recycled to main process, and the residual is fabricated to make a waste form. As a result, the decay heat from daughter nuclides such as Ba and Y seems to be maximum 4.6 times higher than that from their parent nuclides such as Cs and Sr. The thermal release from Cs and Sr in the LiCl waste is the maximum around the first one month, so an cooling system operation for some time at the beginning would be suggested to control a rapid increase in the temperature of the LiCl waste salt.

The electrolytic reduction of spent oxide fuel involves the liberation of oxygen in a molten LiCl electrolyte, which results in a chemically aggressive environment that is too corrosive for typical structural materials. So, it is essential to choose the optimum material for the process equipment handling molten salt. In this study, corrosion behavior of Inconel 713LC, Inconel MA 754, Nimonic 80A and Nimonic 90 in the molten salt $LiCl-Li_2O$ under an oxidizing atmosphere was investigated at $650^{\circ}C$ for 72~216 hrs. Inconel 713LC alloy showed the highest corrosion resistance among the examined alloys. Corrosion products of Inconel 713LC were $Cr_2O_3$, $NiCr_2O_4$ and NiO, and those of Inconel MA 754 were $Cr_2O_3$ and $Li_2Ni_8O_{10}$ while $Cr_2O_3$, $LiFeO_2$, $(Cr,Ti)_2O_3$ and $Li_2Ni_8O_{10}$ were produced from Nimonic 80A. Also, corrosion products of Nimonic 90 were found to be $Cr_2O_3$, $(Cr,Ti)_2O_3$, $LiAlO_2$ and $CoCr_2O_4$. Inconel 713LC showed local corrosion behavior and Inconel MA 754, Nimonic 80A, Nimonic 90 showed uniform corrosion behavior.

Salt is a vital inorganic substance to human body and is seasoning in food. It is an absolute alternating factor on fermented food. What's more, in the oriental medicine, it is widely used to raise the pharmacological effect as a component of a prescription when processing a medicine, and when taking the medicine. Though, Importance of salt is often unaware and it is not used in the right way. focusing on "東醫寶鑑 內景篇 Donguibogam-Naegyeong" I categorized the methods of salt's prescription, dose, processing, seasoning, etc. The contents were compared and studied as well. When salt is used as a medicine, It is used as a main medicine, complimentary(aid) medicine, Jjim-Jil(hot towel or bath etc), vomiting medicine and gargling water. when taking the salt water with other medicine, depending on the type of the medicine, boiled salt water, warm alcohol or salt water, mixing powder medicine with salt water etc The methods are diverse. The reason to process medicine with salt or salt water is to bring the pharmacological Qi(energy) down to increase remedial value. When processing a medicine, kneading dough with salt water and the case using food ingredient as medicine salt was used as seasoning. Kneaded mud with salt were used to cover medicine or on the outer surface. This proves that it prevents the dryness and helps the medicine cooked even. Like this, salt is vital and highly-valued medicine in the oriental medicine. learning the right method of using salt and if it were used properly It is considered that it would increase the Pharmacological effect.
