본 연구는 다량 미네랄 6종 및 미량 미네랄 8종이 함유된 천연 미네랄 워터의 기능성을 확인하기 위해 역류성 식도염 유발 동물모델을 이용하여 개선 효과를 분석하였다. RAW264.7에서의 세포 생존율 측정 결과를 통해 미네랄 워터는 세포에 대한 독성이 없음을 확인하였으며, 역류성 식도염 동물모델에서 위 내용물 역류에 의한 식도 손상을 감소시켰으며, 식도 점막 보호 작용으로 인해 세포 연접 단백질 발현을 억제하였다. 따라서, 미네랄 워터의 식도 보호 작용은 조직 내 염증성 단백질 및 점막 재생 관련 단백질을 조절함으로써 나타난 것으로 사료된다. 이러한 연구 결과를 통해, 미네랄 워터의 기능성을 확인함으로써 음용수, 식품 생산 등의 다양한 산업 분야에서의 활용성과 가축 생산에 있어 면역증진 및 염증 관련 질병에 대처할 수 있는 친환경 기능성 사료첨가제로서의 미네랄 워터의 이용 가치를 확인할 수 있었다.

The purpose of this study was to analyze and compare the contents of minerals and ionic components in domestic commercial natural mineral waters, and to investigate the relationship between water quality and characteristics of suspended and rocks there of its source. All mineral waters tested in this study met the korean mineral water quality guideline, although chemical components varied widely depending upon the geological characteristics and degree of urbanization of the source area or physical water treatment method. The water quality of commercial bottled water was different from that of source water, especially in cationic components, and showed a tendency to become worse with time elapsed. The water quality on the bottle was also different from the measured quality.

We are calling the erupting ground water as drugwater or mineral water in Korea and thinking those water is good for health from ancient. But most of them were used by mountainer as drinking water and food making water. Authors tried to investigate the evidence of contamination by user on the 10 erupting ground water and gained following results: 1. All of the mineral, waters on 10 area in Seoul were unfitable to drinking water standard. 2. In the view of the bacteriology 80% were contaminated by coliform group. 3. The highest value of the free carbon dioxide contents were 652.96 ppm at Sam Sun Mineral Water.

Water is an essential ingredient to brew coffee. Mineral contents in the water can affect both water quality and taste quality of coffee. The effects of minerals in the water on sensory characteristics of coffee were investigated in different water samples (A: Arisu, B: Claris, C: Spring water, D: Samdasoo, E: Evian, Distilled water as control). Based on the results of quantitative descriptive analysis (QDA), there were statistically significant (p<0.01) in flavor, acidity, bitterness, sweetness, body and aftertaste according to different water samples used to brew coffee. The canonical correlation analysis of minerals (Ca, Mg, Na, K) and taste (acidity, bitterness, sweetness) indicated that there were highly correlated in the relationship between bitterness and Mg content. A strong negative relationship was shown between bitterness and acidity, sweetness. A result of preference test using hedonic scale showed an inverse linear relationship between taste quality and total mineral contents.

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 $200{\pm}10CFU/mL$, 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.

I have conducted two testings to find out which water is better for drinking water. First, I made 20 mM L-DOPA solutions by solving L-DOPA (3,4-Dihydroxyphenylalanine) in tap water, Waters' mineral water and reverse osmotic water. Then I measured activities after adding Tyrosinase (purifide enzyme, step 3), which was extracted from Salanum melongena(mad apple), in each L-DOPA solution. Second, I solved 0.1, 0.5 and 0.9% salt in each 20 mM L-DOPA distilled water to measure activity of each salt solution. The results of the testings are as follows: 1. 10 minutes after adding Salanum melongena(mad apple) tyrosinase in each L-DOPA solution, activity of Waters' mineral water was 0.867 tap water 0.777 and reverse osmotic water 0.742. 2. Activity of Waters' mineral water was higher than that of tap water by 10.4% and higher then reverse osmotic by 14.4%. 3. Activity of Waters' mineral water was much higher than that of 0.9% salt water by 41.8%. 4. The optimum pH of Salanum melongena (mad apple) tyrosinase is 9.0. Most enzymes working in the human metabolism are alkaline and body fluids' pH also alkaline. In conclusion, an alkaline water is believed better than an acidic water for drinking.

지하 943 m(3호공)로부터 취수한 경산 광천수의 유$\cdot$무기성분을 분석한 결과 총 17종류의 성분 중 무기물은 11 종류가 검출되었으며 무기성분 중에서는 나트륨과 칼슘 성분이 많이 함유되어 있는 것이 특징이었다. 그리고 구리와 납과 같은 중금속과 탄산가스 및 유화수소는 검출되지 않았다. 그리고 항산화 활성, 항돌연변이원성 및 인간암세포 성장억제 실험 결과 항산화 활성에서는 비교적 약한 활성을 나타내었다. MNNG, 4NQO, Trp-P-1및 $B({\alpha})P$와 같은 돌연변이원을 이용한 미생물 수준에서의 항돌연변이원성 실험 결과 S. typhimurium TA98에 대해서 간접변이원인 Trp-P-1은 시료 농도 $200{\mu}g/plate$ 첨가 시 $54\%$의 억제 활성을 나타내었다. 또한 S. typhimurium TA100 균주에서 4NQO 및 MNNG는 각각 $65.8\%$ 와 $58.6\%$의 억제활성을 보였으며 $B({\alpha})P$ 및 Trp-P-1에 대해서도 각각 67%와 63%의 높은 억제활성을 나타내었다. 그리고 광천수의 항암활성을 규명하기 위한 암세포 성장억제 효과에서는 시료농도 $50{\mu}g/well$ 첨가 시 A549, Hela, AGS 및 MCF-7에 대해서 각각 $66\%,\;45.6\%,\;37.7\%$ 및 $47.6\%$의 억제효과를 나타내었다. 또한 인간 정상 신세포 293에 대한 온천수 농도에 따른 세포독성 효과는 $20\%$ 이하의 낮은 생육 억제율을 보였으며 이것은 광천수가 정상세포에 대해서는 비교적 낮은 독성효과를 나타냄을 알 수 있었다.

The characteristics of Far-infrared rays mineral water(FIR water) have been compared to the tap water by means of relationship between FIR water and Nuclear Magnetic Resonance spectroscopy(NMR), FIR water and thermography FIR water and velocity of blood FIR-water and pH, FIR water and dissolved oxygen(DO), FIR water and Oxidation-Reduction Potential(ORP) using the development FIR water purification of grand prix system. From the experimental result are quite satisfactory when compared with the tap water. Also the FIR water were evaluated to see if those are tasty and healthy using the Hashimoto's Mineral Balance Index. As a result FIR-water was found as tasty and healthy.

The resistivity of soils depends on grains size, porosity, water saturation, pore fluid resistivity, caly contents and son on. It is very important to understand the relationship between resistivity and such physical properties of soils, in order to interpret and evaluate ground conditions by using resistivity data obtained from electrical resistivity prospecting. In this paper, to study the relationship between resistivity and physical properties of soils, the resistivity of glass beads and compacted soil samples both in saturated and unsaturated conditions is measured. As the results, the resistivity of saturated soils depends mainly on porosity and clay contents, while that of unsaturated soils is sensitive to compaction conditions, and decreases with increasing water content until the optimum water condition, that is the maximum dry density. But, the relationship between resistivity and water saturation for soils is unique, being independent of compaction energy. Also, the resistivity ratio decrease with increasing water saturation, followed by no significant change of resistivity ratio over 80 percent of water saturation (the optimum water content).

This study has been performed to evaluate mineral water quality by using four parameters [Mg]/[Ca], [Na]/[K], [Mg]+[Ca]/[Na]+[K] and total hardness(as CaCO3 mg/ℓ). The four parameters has been ploted in a general scale and logarithmic scale, respectively. The method of general scale is not applicable for evaluation on several parameters. Therefore, the logarithmic scale is applied instead to settle the problem. The evaluation of the water quality is based on standard sample S, and the results of the 6 domestics and 5 overseas sample evaluation are as follow. At present, evaluation of the water quality on the mineral water can be done by using four parameters calculated from only cation concentration printed on the bottle's marking.
