The purpose of this study is to measure the levels of eluted and dissolved CO2, and CO, volatile organic substances and radiation composition of Cheongsong mineral water which were collected from November 2019 to July 2020 during the autumn, spring, and summer seasons at collection points located in the upper, middle and lower spring waters. Data of the upper, middle and lower spring waters include the following: the amount of eluted water (average value±standard deviation, mL/min) was 30.07±0.52, 15.03±0.16, 23.73±0.42, and the amount of CO2 gas was 1,000 ppm or more. In addition, there was no detection of CO or total volatile organic substances (TVOC) and the radiation dose was 0.08 to 0.13. μSv/h. A blank test value of 0.08 to 0.10 μSv/h, when compared with the median value, showed a high value of 0.02 μSv/h, and the uranium test results provided by the Cheongsong-gun Office were 0.0118 mg/L (date 2019.06.18) and 0.0091 mg/L (date 2020.06.04.) respectively, which was less than the permission limit of 0.03 mg/L. However, it is believed that further research using more precise devices is needed in order to guarantee the safety and health of the water.

This experiment was aimed to identify concentrations of mineral nutrients in leaf lettuce (Lactuca sativa) grown on hydroball aquaponics and in the water for growing fish by conducting two experiments. The experiment I (Expt. I) was conducted with 12 fishes (F12) with and without filter, hydroball and plants (H12 (12 fishes, hydroball), FHP12 (12 fishes, filter, hydroball, 6 plants) and HP12 (12 fishes, hydroball, 6 plants)), and the experiment II (Expt. II) was with and without plants (FH15 (15 fishes, filter, hydroball), FHP15 (15 fishes, filter, hydroball, 6 plants)). The pH level in the water of all the treatments was decreased during the growing period, and the pH and EC of the water were lower in all the treatment with plants than those without plants in both Expt. I and Expt. II. When compared with adequate nutrient concentrations for hydroponics, nitrate nitrogen (NO3-N) and phosphorus (P) concentrations in the fish growing water were higher under the FHP15 treatment in Expt. II; however, potassium (K), calcium (Ca), and magnesium (Mg) were only 16, 49, and 82% of hydroponics, representatively, and iron (Fe) was not detected. The fresh weight of lettuce harvested from the FHP15 treatment was 38 g, only a 30% of marketable lettuce yield. The T-N and P contents of the leaf tissue grown under the FHP15 treatment were close to the optimal level; however, the K, Ca, and iron (Fe) contents were less than the optimal with no deficiency symptom.

As people seek a healthy, wealthy, and quality life more than before, interests in mineral water are picking up and the consumption continues to increase accordingly. In an experiment to examine changes in the water quality after mineral water on the market was kept indoor and outdoor for four weeks, there seemed to be no problem in external appearance. Water kept in an outdoor storage contained more odor-savor than water kept in an indoor storage. Odor was not detected in 90% of the sample, and savor not in 80% of it. As for the mechanism of odor-savor generation, the elution of chemical substances from a container may be taken into consideration. In general, odor and savor have turned out to be in close correlation to each other. The average number of bacteria in the sample mineral water was 200±10 CFU/mL, and such factors as area of storage and ozone post-treatment did not cause significant effects on the reproduction of common microbes. Hence, it is thought that strict regulations on a production process and reduction of the period of circulation will contribute to customers consumption rates.

This experiment was conducted to investigate effect of brine mineral water (BMW) on growth performance and properties of blood in weaning pigs. Treatments allotted were 0% (general water), 2%, 3% and 5% BMW. In growth trial, a total of 36 weaning pig barrows [(Landrace×Yorkshire)×Duroc] weaned after 21 days with an average initial weight of 5.38±0.89 kg were used. Each treatment had 3 replications of 3 pigs per pen in a randomized complete block design. Weaning pigs were investigated for growth performance, complete blood corpuscle count and blood biochemical assay. In results, growth performance of 2% and 3% treatment groups were significantly higher than other groups (p<0.05). In addition, high density lipoprotein cholesterol was significantly (p<0.05) higher in 2% group than other treatment groups. On the other hand, mean corpuscular volume of supplement of BMW treatment groups were significantly (p<0.05) increased than control. Therefore, this study suggests that supplementation of BMW could improve growth performance and level of red blood cell in weaning pigs.

부영양호 신갈지의 수질개선을 위하여 이미 개발된 천 연물질 혼합제(PMC)의 수질개선능(WQI)에 수온변화가 어떠한 영향을 미치는지 현장실험을 실시하였다. 실험결 과 식물플랑크톤, BOD, 총인 등은 20􀆆C 이하에서는 70% WQI 이상을 보였으나 25􀆆C 이상에서는 40% WQI 이하로 오히려 감소하였다. 한편 수온의 증가에 따라 남조류에 대해서는 WQI는 감소하였고, 규조류는 수온변화에 상관 없이 90% 이상 높은 WQI를 나타냈으며, 박테리아와 총 질소는 수온과 상관없이 매우 낮은 WQI를 보였다. 이상 의 결과들은 PMC의 수질개선능이 수온과 밀접한 관계를 가지며, 25􀆆C 이상의 고온기에 Microcystis aeruginosa가 우점하는 남조대발생보다 겨울철 저온기에 우점하는 규 조류에 더 효과적일 것으로 판단되었다.

This is a basic study of Cheong-song mineral water, which has high contents of Ca and Mg for making noodles as well as for general cooking. The test results of the noodles manufactured and cooked with mineral water were compared to those manufactured and cooked with distilled water and tap water. Noodles manufactured with mineral water showed higher values than others in the cooked weight, volume, water absorption ability, turbidity, lightness (L) and redness (a) on the minus scale. This means that we can manufacture cooked noodles that have high weight, high volume, high water absorption ability and high lightness (L) along with a slight green color with Cheong-song mineral water. Cooked noodles manufactured with mineral water showed significant differences in the cooked weight and volume compared to those manufactured with distilled water. Also, cooked noodles manufactured with mineral water showed significant differences in moisture absorption, turbidity, lightness (L), redness (a) and yellowness (b) compared to those manufactured with distilled water and tap water. Commercial noodles cooked in mineral water showed significant differences in the cooked weight and redness (a) compared to those cooked in distilled water and tap water. Further, commercial noodles cooked in mineral water showed significant differences in weight, volume and brightness (L) compared to those cooked in distilled water.

The objective of this study was to evaluate the sperm liquid storage diluted with Brine Mineral Water (BMW) in miniature pig. Therefore we performed to find optimal concentration of BMW. The ejaculated semen from miniature pig was collected by gloved-hand method. The collected semen was diluted with dilution solution (Mulberry Ⅲ; modified-Modena B) which BMW was added. Concentration of BMW was 0, 2.5, 5, 7.5, 10 and 12.5% in dilution solution. The diluted semen was preserved at 17℃. Sperm ability was estimated by viability, capacitation acrosome reaction using chlortetracycline (CTC), hypoosmotic swelling test (HOST), morphologic abnormality. The diluted semen was observed for 7 days. The viability was significantly measured higher at 2.5% concentration of BMW than other groups (p<0.05). The AR-pattern of CTC analysis was significantly measured lower at 12.5% concentration of BMW than other groups (p<0.05). However, abnormality was not significantly different among all the groups (p<0.05). In conclusion, viability of sperm was the highest at 2.5% concentration of BMW but BMW had a negative effect on HOST, capacitation and acrosome reaction in sperm of miniature pig.
