최근 후생성은 `90년의 국민영양조사의 개요를 정리하였다. 이에 의하면 영양의 섭취상황은 지방, 단백질, 탄수화물 등의 다량영양소나 비타민, 미네랄등의 미량영양소가 모두 감소의 경향을 나타내고 있다. 이러한 가운데 칼슘은 변함없이 1일의 필요량을 충족시키지 못하는 상태로 조사개시 이래 한번도 충족된 적이 없다고 하는 심각한 상태로 되고있다. 또 지방섭취도 감소경향에 있지만 열량비(比)로 보면 적정치를 넘고 소금에 있어서는 다시 증가하는 쪽으로 바뀌고 있다. 그러므로 심장병, 고혈압, 골다공증등의 성인병이 우려되고 있다. 개요를 발췌하여 게재하면 다음과 같다.

에어로졸은 인위적으로 발생하거나 자연적으로 발생하는 먼지(토양 발생인 먼지, 생물학적 비해염입자, 유기입자 둥)로 나뉘어지는 데 자연적으로 발생하는 먼지의 대표적인 사례로 황사를 들 수 있다. 이는 시정악화나 해수성분의 변화, 강수의 pH 변화 등 여러 가지 방면에서 영향을 주고 있는 것으로 나타나고 있다(Parungo et al., 1995). 동북아시아 지역의 지역적인 특수성으로 인해 미네랄 에어로졸 표면에서의 화학반응 활성화가 황산염이나 질산염의 생성을 유발한다는 여러 가지 보고가 있다. (중략)

양계산업에 있어 계사내 환경문제와 계분 처리문제는 향후 업계에서 풀어가야 할 큰 숙제로 부각되고 있다. 특히 육계사육에 있어서 깔짚은 가격상승, 구매의 어려움 등으로 심각한 상황이 예상되고 있다. 현재, 깔짚 원료인 왕겨와 톱밥의 가격이 높게 오르고 있으며, 특히 계절에 따라 수요가 일정하지 않아 구입하는데도 큰 어려움을 안고 있는 실정이다. 본고는 고유가, 고사료 시대 어려움이 지속되고 있는 가운데 양계장의 생산비 절감을 위해 계분처리 문제 해결은 물론 깔짚의 대체물질로 미네랄라이트(활성탄)를 이용해 새로운 돌파구를 마련하고 있는 알파엔오메가(대표 이기상)를 찾아 깔짚재로써의 효과 및 계분생산의 활용도에 대해 취재하였다.

질적 양적 성장을 해온 양계산업이 최근에는 계분처리 등 악취문제로 인한 민원발생과 각종 소모성 및 전염성 질병으로 이중고를 겪고 있다. 이에, 주식회사 대자연(사장 신왕기, 이하 대자연)은 15년간의 연구 끝에 고전압과 특수합금을 활용한 고전압 미네랄이온활성수로 악취문제와 세균을 한방에 해결할 수 있는 시스템을 개발했다. 무독성으로 2차 오염물질을 생성하지 않고 세균이나 악취물질을 세정하거나 흡착시키는 임시방편적인 방법이 아니라 세균과 악취물질자체의 분자화학 결합을 깨트려 분해하는 근본적인 문제해결방법으로 음수로 먹이거나 분무로 뿌려주면 된다. 이번호에는 대자연을 소개코자 한다.

This study was aimed at investigating the change of blood mineral and enzyme activity during growth period of velvet antler in Korean spotted deer. Samples of blood, obtained from the jugular vein of twenty-five deer(4 to 6 year-old males), were taken in 10 days interval from just after casting to 50 days. Deer were randomly selected from the farm, and samples were analyzed for blood parameters like mineral concentration and enzyme activities. No significant differences found in calcium and phosphorus concentration in blood whereas sodium, potassium and chloride concentration were significantly changed with antler growth. There were no significant differences in alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, $\gamma$-glutamyl transferase and lactate dehydrogenase during growth of antler, but alkaline phosphatase concentration was increased with growth of antler, and the highest concentration was obtained on the 50 days after casting. Creatine kinase and lactate dehydrogenase activities for the deer tested in this experiment were higher than those of other animals.

Corrosion inhibitors including calcium hydroxide have been used to prevent corrosion in the pipes for tap water supply. The corrosion index (i.e., Langelier Index) differs by area and water quality. The corrosion indices of the areas studied differed by more than 2.0. The 'homogenized' calcium hydroxide was added to the treated water at the K water treatment plant, in order to increase the value of the corrosion index and the concentration of calcium. As the result, the concentration of calcium was increased while the turbidity and pH changed little. The corrosion rate of the tap water with the 'homogenized' calcium hydroxide could be slowed down pretty much. The results suggested that the technology of 'homogenization' of calcium hydroxide can applied to tap water and desalinated water to prevent corrosion in water pipes even in corrosive pipes.

In this study, the inorganic insulating material was fabricated with quartzite, ordinary portland cement(OPC), lime and anhydrous gypsum. After characteristic analysis of slurry, the optimum mixing ratio was derived with different $CaO/SiO_2$ mole ratio. Based on derived mixing ratio, the inorganic insulating material was fabricated at different water content and hydrothermal synthesis conditions. Specific gravity was $0.26g/cm^3$, compressive strength was 0.4 MPa, and thermal conductivity was 0.064 W/mK. This properties were enhanced performance of conventional ALC (Autoclaved Lightweight Concrete). And it can replace organic insulation with harmless inorganic insulation through continues research and development.

The common recognition which the organic baby foods is compared as safe to baby does not mean there is especially plentiful nutrition in organic product. Because the mineral content of agricultural products is partly influenced by the soil quality, chemical fertilizer may change the mineral contents of the products. In that case, it may result in the possibility of the change of the contents of the agricultural vegetable products. However, the contents and the compositions of vitamin, carbohydrate, protein and fatty acids does not change largely from their original nutrition facts of the organic foods. The most advantage of organic baby foods seems to protect the agricultural products from the possibility of chemical contamination. It must be the most strong desire of all the consumers to provide and to nurse their babies with the high quality of baby foods made from organic food materials which are safe, reliable and healthier. That would also be a sincerely good way for the environment and ecosystem of the world.

This is the basic study on the extraction characteristics of Omija (Schizandra chinensis) for juices of Korean traditional foods. Extraction is being performed as 25 times of the solvent ratio at room temperature and at $65^{\circ}C$ with deionized water, tap water and Cheong-song mineral water which have high contents of Ca and Mg. The overall good results of the extraction conditions are calculated from the values of L (Lightness), redness (a), yellowness (b), soluble solids content, acidity, pH levels and the DPPH radical scavenging activity by using the electron donating ability (EDA). The results are as follows: 12 hours of room temperature and 6 hours at $65^{\circ}C$ were good extraction times. The Cheong-song mineral water at $65^{\circ}C$ is available for rapid extractions when compared to deionized water and tap water. A longer extraction time shows lower values of acidity but increasing values of soluble solids content and DPPH radical scavenging activity when using the electron donating ability. The best sequences for the extractions are Cheong-song mineral water followed by tap water and distilled water after overall consideration.
