Deep sea water is deeper than 200 m in depth and maintains cool temperatures. It is clean seawater not contaminated by E. coli and other general bacteria. Because deep sea water is a recyclable resource with high industrial value, activities for commercial use are vigorously developing. We investigated safety, quality characteristics, and mineral contents of prototype products using deep sea water as a substitute for a curing agent and compared it with existing commercially processed products. This study examined the potential of deep sea water as an alternative to curing agent solution. As a result, safety and quality characteristics of processed meat products with deep sea water were not different from commercially processed meat products, but mineral contents were higher in processed meat products with deep sea water. Deep sea water could be widely used as purity salt and purity minerals that can replace chemical substances such as chemical salts. A new, active food market using deep sea water will emerge in the near future.

Quality and sensory characteristics of tofu prepared with concentrated to 8 $^{\circ}Brix$ deep ground sea-like water (SW) were investigated to check the availability for coagulants. The tofu was coagulated with three kinds of commercially coagulant, such as $MgCl_2$, $CaSO_4$ and glucono-${\delta}$-lactone. Different amounts of SW and soybean milk were added: SW-20 g/L, SW-25 g/L and SW-30 g/L. The moisture content and pH were significantly lower in which preparation with glucono-${\delta}$-lactone coagulated tofu, and others has not significantly difference each other. The mineral contents in the coagulant influenced the mineral content of the tofu, which contained larger quantities of major minerals. However, the mineral content of the tofu was not affected of the mineral concentration in the coagulant. The L and b values of the tofu prepared with SW were not significantly different. The hardness of the tofu prepared with the commercial coagulants was significantly lower than that of the tofu produced with the SW. The sensory property was lower when the hardness was lower and higher. In conclusion, the quality characteristics of SW-prepared tofu were not significantly different from those of the tofu prepared with the commercial coagulants, but the texture and the taste of the SW-prepared tofu were excellent.

평창올림픽 빙상장에 해양심층수를 이용한 냉난방시스템 가동 방안이 추진된다. 국토해양부는 태양광이 도달하지 않는 수심 200m 아래의 해양심층수가 연중 $2^{\circ}C$ 정도를 유지하는 점을 이용해 세계 최초로 올림픽 빙상장에 한국해양연구원의 '해수냉난방시스템' 및 '해수온도차 발전' 연구개발 사업 성과를 적용한다고 밝혔다. 이번 기술이 전기에어컨이나 흡수식 냉동기 등에 적용되면 기존 시스템에 비해 에너지는 60%, 비용은 82%, 이산화탄소 배출량은 64% 줄어들게 된다.

Effects of deep sea water on blood glucose and the Langerhans' islet in STZ-induced type I diabetic mice were investigated. Results showed that diabetic symptoms in STZ-induced diabetic mice improve with a supplement of deep sea water. That is, the level of blood glucose was lower, the area of the Langerhan' islet was wider, and the number of pancreatic $\beta$-cells was larger in the diabetic mice supplied with deep sea water than in the diabetic mice supplied with tap water. Such effects might be related to the high level of Mg$^{2+}$ in the deep sea water.

The objective of the present study was carried out to clarify the effects of deep sea water on the growth and maturation of $Porphyra$ (Rhodophyta, Bangiales). Foliose thalli for indoor culture were collected from Yeongok ($P.$ $okamurae$) in Gangwon Prefecture, Tongyeong ($P.$ $suborbiculata$ f. $latifolia$) and Namhae ($P.$ $yezoensis$ f. $narawaensis$) in Gyongnam Prefecture respectively. Monospores were cultured at five temperatures (5, 10, 15, 20 and $25^{\circ}C$) with a photon irradiance of $80{\mu}m^{-2}s^{-1}$ under photoperiods of 14L:10D and 10L:14D in surface, deep and mixed seawater in respectively. The fast growth of foliose thalli were observed in $P.$ $suborbiculata$ f. $latifolia$ cultured at deep seawater under $15^{\circ}C$ and 10L:14D. In three species, the optimum growth occurred at 10 and $15^{\circ}C$ under deep and mixed seawater and short day-length. In general, monospores from the cultured thalli were liberated within three weeks after incubation under $10-25^{\circ}C$ and both photoperiods. From the result of this study, deep seawater is considered that the natural species of the genus $Porphyra$ can be useful for the development as the new cultivars.

To verify the characteristics of deep ocean water, oceanographic observation and qualitative analysis were carried out from March of 2001 to February of 2002. Spatiotemporal variation of water quality of deep ocean water were discussed from survey results around development site and along northeastern coastal sea of Korean peninsular. Vertical distribution of water temperature and salinity were measured, and sampled seawater were analyzed in order to determine the definition of deep ocean water resource and the position of intake device for supplying qualified deep ocean water resource.

인간에 의한 바닷물 이용은 역사와 더불어 시작된 것이기에 새삼스러운 일은 아니다. 그렇게 생각하는 것은 자연계에서의 물 순환과정 속에 언제나 일어나는 해양환경의 증발현상이라고만 인식하고 있기 때문이다. 더구나 자연현상으로 생각해 해양수 이용이라는 생각을 안 할 뿐 이다. 물론 자연현상이므로 이용이라고 정의되지는 안는다. 육지의 담수를 공급 받기 어려운 상황에서는 해수를 담수화하여 이용하는 예는 일반화된 기술이다.(중략)

The more the population grow, the severer the shortage of a basic human needs such as clean water, food, energy resources and so on. Recently, we aware that deep sea water can be utilized to solve comprehensively food, energy and water problems. In this study, inhibitory effect of the deep sea water of east coast (DSW) on platelet aggregation were investigated using washed platelet and beneficial effect of the change of lipid concentration on serum at various time intervals for three weeks. In this study six groups of 6-month-old Sparague-Dawley rats were examined. An intact group served as controls (C-1D : breeding for one day, C-1W : breeding for one week, C-3W : breeding for three week). The fourth group (1D-DSW) supplemented with DSW for one day. The fifth group (1W-DSW)supplemented with DSW for a week. The sixth group (3W-DSW)supplemented with DSW for three weeks. The total cholesterol and triglyceride concentration on serum of supplemented groups with the DSW for one or three weeks were significantly decreased. The serum HDL-cholesterol level in the DSW groups were significantly higher than the level in the control group. The supplementation of DSW for one day did not appear to have such a beneficial effect on lipid level. The ability of platelet aggregation of supplemented groups with DSW was less than control group. These results suggest that supplementation with DSW is positively influence on lipid concentration and platelet aggregation.
