This study was conducted over eat-nut foods in Andong area to measure the salt concentration and to compare the result with the optimum gustation of salt concentration in usual diets. The results were as follows: 1. Mean salt concentration of eat-nut foods was similar to the optimum salt concentration by sensory evaluation. 2. The salt intake through the menu was about twice of the recommended intake by Korean Food Research. 3. The foods with a large serving size contributed to the increase of salt intake, suggesting that the serving size needs to be adjusted. 4. It is recommended that the consumption of high salt foods needs to be reduced while increasing that of fresh fruit and vegetable in the diet behavior on eat-out foods.

The WRAP-SALT (Water Rights Analysis Package-SALT) simulation includes computation of end-of-month reservoir storage concentrations and mean monthly reservoir outflow concentrations for each month of the simulation. The model computes reservoir storage loads and concentrations based on load balance accounting algorithms and computes concentrations of water released and withdrawn from a reservoir as a function of the volume-weighted mean concentration of the water stored in the reservoir in the current month or previous months. A load budget accounting of the various component load inflows and outflows entering and leaving a reservoir is performed. A time history of storage concentrations computed for previous months is maintained for use in the lag procedure. This study presents computational methods for routing salinity through reservoirs for incorporation into WRAP-SALT simulation routines and methods for determining values for the parameters of the routing methods.

This study was conducted to establish a management plan for the Songrim woodland restoration by analyzing the site characteristics of the Songrim Woodland Natural Monument (Natural Monument 445) in Hadong-Gun, Gyeongsangnam-Do, Korea. The Songrim woodland was a pure pine forest. To stimulate the growth of sub-trees or mid- story vegetation in both a non-rest year forest and a rest year forest, it is recommended to take a silvicultural practices such as pruning because canopy of over-story trees was closely covered. The Songrim woodland in the non-rest year forest severely competed among individual trees of DBH classes of 60 cm and height of 18 m, while the woodland in the rest-year forest competed with DBH classes of 62 cm and height of 10 m, respectively. Soil physical property such as soil hardness, soil pore space rates, and pF 2.7 was restored following the rest-year forest designation. Mean salt concentration in the Songrim woodland soils was 0.006%. The result suggests that it is needed to take a study to prevent the salt inputs to conserve the Songrim woodland.

Physiological responses to salinity stress were evaluated in six rice genotypes differing in their tolerance to salinity at the seedling stage. Susceptible genotypes ('Dongjingbyeo', 'Hwayeongbyeo', and 'IR29') showed salt injury symptoms (mean 8.8) and higher visual score under salt stress than that of tolerant ones ('Pokkali', 'IR74009', and 'IR73571'). As salinity affects growth and physiological parameters, the six genotypes thus showed significant reduction because of salt stress. Tolerant Japonica/Indica bred lines ('IR74009', 'IR73571') showed lower reduction, 33.9%, 34.5%, and 50%, respectively, in plant seedling height, dry shoot weight and dry root weight than those of the susceptible Japonica varieties ('Dongjingbyeo', 'Hwayeongbyeo'), and the highest reduction under salt stress was observed in dry root weight, followed by dry shoot weight and seedling height, respectively. Shoot $Na^+$ concentration of IR74099 and IR73571 was lower than that of the susceptible varieties, 'Dongjinbyeo' and 'Hwayeongbyeo'. There were no significant differences among genotypes in root $Na^+$ concentration. Shoot $K^+$ concentration showed a reverse tendency compared to shoot $Na^+$ concentration. IR74009 and IR73571 had considerably lower ratio compared to 'Dongjinbyeo' and 'Hwayeongbyeo' in $Na^+/K^+$ ratio of their shoot and was not different the tolerant check, 'Pokkali'.

This study was conducted to develop the fermentation kinetic modeling for the prediction of pH and acidity changes in kimchi at isothermal and nonisothermal fermentation temperatures(0~15$^{\circ}C$) and salt concentrations(1.5~4.0%) using the traditional two-step method and alternative one-step method. The calculations of the two-step method of pH and acidity change during fermentation followed the pattern of the first order and zero order, respectively. The reaction rate constant of pH by the first order was increased from 0.008 {TEX}$day^{-1}${/TEX} to 0.017 {TEX}$day^{-1}${/TEX} by increasing the temperature from $0^{\circ}C$ to 15$^{\circ}C$ at 2.75% of salt concentration, and was decreased from 0.013 {TEX}$day^{-1}${/TEX} to 0.010 {TEX}$day^{-1}${/TEX} by increasing the salt concentration from 1.5% to 4.0% at 5$^{\circ}C$. For the pH and acidity of Kimchi, the zero order had a higher correlation than the first order to the estimate of the kinetics parameters by the one-step method. The {TEX}$E_{a}${/TEX} ranges of pH and acidity were 61.057~66.086 and 62.417~68.772 kJ/mole with different temperatures and salt concentrations. This one-step method had smaller and more realistic estimates of error(p〈0.05). The effective temperatures, {TEX}$T_{eff}${/TEX}, with 0~15$^{\circ}C$ of square function type of 12 hr intervals were 12.85, 11.48 and 12.46$^{\circ}C$ as increasing the salt concentration, 1.50, 2.75 and 4.00%, respectively. The {TEX}$T_{eff}${/TEX} were higher values than the mean temperature(7.5$^{\circ}C$).

There are several types of salts that can be classified into raw salt(Chunil salt), purified salts(NaCl reagent grade) and processed salts(Bamboo salt, Purple bamboo salt using in this study) in Korea. Salts has been utilized for the food as well as for the drug in the Oriental Medicine. Purple bamboo salt(PB-salt) was made by heating up to 1300℃ nine times after putting the raw salts in the bamboo. Since salt is generally known to cause the blood pressure to elevate, this study was conducted to investigate the effect of PB-salt on an adverse reaction of the blood pressure elevation. The experiment was performed with the 2 protocols ; 1. Effect of NaCl and PB-salt administration i.v. with the different the concentration(250, 500, 750, 1000mg/kg) on a mean artery blood pressure(MAP) change. 2. Effect of 500mg/kg NaCl and PB-salt administration p.o. for 6 days on the systolic blood pressure change. The results were as follows; The results were as follows; In a short minute change of blood pressure by direct method, PB-salt adminstration did not induced the hypertension unlike NaCl adminstration. In a date change of blood pressure by indirect method, systolic blood pressure was increased about 12-18% in the NaCl administration group, whereas within 6% in the PB-salt administration group from 2 days to 5 days. These results suggest that PB-salt might have some unidentified ingredient to be changed in the course of processing, making it superior to other salts.

Outdoor cultivation of cyanobacterium Spirulina platensis was carried out for 40 days in a batch mode. A half concentration of the SOT based on the underground water was used as culture medium. Working volume was 5.7 tons with 0.2 m depth. During cultivation, mean water temperature, DO and light intensity were all in proper conditions for the S. platensis growth. The adjustment of pH to over 10 with Na2CO3 and addition of the 1.5% natural salt were very effective to delete contaminant organisms, Chlamydomonas moewusii and Chlorella minutissima occurred one after the other in the culture. The mean productivity of the biomass based on the dry cell weight from 14 to 25 days, after the contaminants were deleted, was 7.8 g ·m–2· d–1, which was relatively high productivity in that a half concentration of the SOT was used for the culture. Underground water used in the culture minimized contaminants invasion and addition of the 1.5% natural salt was effective to delete contaminants as well as acted as mineral supplement in outdoor cultivation of S. platensis. Harvesting using the floating activity of S. platensis was effective from mass floating in day time after overnight without agitation and illumination.
