  • Milk was concentrated by commercial tubular membranes, The permeation rate reduction of hydrophilic membranes (sulfonated poly sulfone (SPSf), polyacrylonitrile (PAN), cellulose acetate (CA)) was found not to be large but hydrophobic membranes to be pronounced considerably, In the case of UF concentration total solids, proteins, fats and minerals were increased as concentrated but carbohydrates decreased. NF showed the same behavior except carbohydrates showing small reduction rate.

  • Chromium(III) picolinate, a highly bioavailable compound, is known to be used for supplementing essential chromium(III) to human beings and animals. Two different methods were used to synthesize chromium(III) picolinate. The synthetic products were characterized by elemental analysis, FTI-IR, high performance liquid chromatography (HPLC) and MALDI-MS.

  • Hair tissue mineral analysis is widely accepted for assessing essential and toxic elements which can give information about disease, metabolic disorder, nutritional imbalance, drug abuse, environmental exposure and so on. In Oriental Medicine, hair have been used as a diagnostic method which reflects the physiological and pathological status of body, especially kidney system(腎臟) and blood(血) like the quotations from Donguibogam(東醫寶鑑), 'hair belongs to kidney system(髮屬腎)' and 'hair is the remainder of blood(髮者血之餘)' Therefore we have suggested that HTMA have possibility to be utilized for screening and treatment for obesity, growth disorder, general deficiency syndrome(諸虛證), etc. in Oriental Medicine.

  • Deformed vertebrae by cold shock in Rhynchocypris oxycephalus were discovered. Deformity was externally noticed in the caudal penducle region of R. oxycephalus. Radiographic and histologic investigation confirmed the deformity. Especially, histological investigations provided the fact that extensive fusion between neighbouring vertebrae is caused by removal of endogeneous mineralized tissue. Deformed vertebrae appeared suggesting the direct evidence of vertebral fusion had arisen internally by cold shock in this species.

  • 머드는 알루미늄, 철, 마그네슘 등의 미네랄이 풍부하여 원적외선 방사율이 높고, 미량 포함된 단백질과 비타민은 피부의 세포조직을 강화하고 탄력성을 주며, 항균, 소취 등의 기능을 보유하고 있다. 이러한 유익한 기능을 가진 머드를 매일 사용하는 면타올에 적용하려 하나 무기 염재인 머드는 섬유와 친화성이 없어 일반 염료처럼 고농도로 섬유에 염색되지 못하고 있다. 본 연구에서는 섬유의 촉감에 영향을 미치지 않으면서 머드의 염색농도를 높이기 위해, 4종의 고착제를 이용한 염색법을 검토하였다. 먼저 식물성 단백질액으로 면타올을 전처리하고 나노입자의 머드액를 사용하여 염착시킨 경우가 가장 진하게 염색되며, 염색견뢰도 측정 결과 세탁과 땀에 모두 우수한 것으로 나타났다.

  • This paper demonstrates a variable capacitor using fluids as dielectric material and investigates the possibility of its application to a magnetic resonance microscopy's coil. The capacitor structure was integrated with a microfluidic channel and the capacitance was measured while changing the filling percentage of fluids in the channel. The measured capacitance when filling DI water and mineral oil was changed from 1.7 pF to 12 pF and from 1.7 pF to 2 pF, respectively.

  • In this study, changes of nutrients such as vitamins, minerals, and antioxidants were determined by using a multi-functional grinder. Contents of vitamin C and vitamin $B_1$ were measured by HPLC, and antioxidant activity was estimated toward free radical scavenging effect in using DPPH. Contents of minerals(Zn, Mn, Fe, Mg, K, and Ca) were computed by ICP-Mass. Results identified that the contents of vitamin C was $44.06{\pm}10.86mg/kg$ in mandarine, $132.1{\pm}22.80mg/kg$ in orange, and $12.79{\pm}2.01mg/kg$ in pineapple by using the hand blender for 3 minutes, and the loss rate of vitamin C contents were 12%, 7%, and 12% in comparison with the control group. In addition, the contents of vitamin C were $41.89{\pm}5.55mg/kg$ in mandarine, $131.51{\pm}12.67mg/kg$ in orange and $16.76{\pm}1.47mg/kg$ in pineapple when using of the grinder for 3 minutes, and the loss rate of vitamin C contents were 16%, 8%, and 17%. The results of vitamin $B_1$ showed a tendency to decrease in the same manner as the content of vitamin C even if there was no significant difference. Furthermore, the result of antioxidant activity revealed that free radical scavenging effect of sample was 60% decreased when using a hand blender and 10% decreased when using a grinder. Thus decrease rate of antioxidant activity when using the hand blender was higher than grinder. Lastly, current study could find any significant differences among the 16 food samples for cooking when employing the multi-functional grinder(p<0.05).

  • Solar salt is manufactured naturally, and therefore, it contains insoluble substances such as sandy compounds. This study is performed in order to effectively produce clean sea salt by removing the impurities in sea salt through filtration and evaporation in a vacuum condition. Brine was concentrated and crystallized at $90^{\circ}C$ by a rotary vacuum evaporator, which was then recovered as salt crystals by filtration, and then the salt was dehydrated. Manufacturing yields were determined by the amount of water evaporation. Brine was concentrated to 40%, 50% and 60% of the initial volume of brine and manufactured salt were designated as 40S, 50S and 60S, respectively. The salt produced by this process is called ESBS (evaporated salt with brine from salt-farm). The yield of 40S, 50S and 60S were 7.22%, 10.79% and 15.06%, respectively. The NaCl concentration of 40S and 50S were 90.38% and 91.16%, respectively. From a sensory evaluation analysis, the most tasty salt was 40S and the bitter salt was 60S. The average contents of sand compound and insoluble substances in ESBS were 0.001~0.012% and 0.067~0.12%, respectively. The mineral compositions, such as Na, Mg, K, and Ca of 40S and 50S were similar with those of the natural solar salt. In solubility tests, the solubility (g of salt/100 mL $H_2O$/sec) of 40S, 50S, and 60S was 0.69, 0.70, and 0.69, respectively. On the other hand, the solubility of natural solar salt was 0.47. By comparing the water reabsorption rate analysis results, water reabsorption rate of 40S and 50S was about 3 to 5 times lower than that of the solar salt. In the aspects of physical and chemical properties, such as minerals, impurities, solubility and moisture re-absorption rate, salts developed in this study are judged to be better than that of the general solar salt.

  • To estimate the nutritional values and the optimum cooking method of the Cow's rumen-reticulum (tripe) which is a Korean traditional food, the nutrients of raw tissue of tripes, the changes in total N, ${\alpha}-amino$ N, calcium and phosphorus contents and nucleotides and their related compounds contents in soup stock prepared of tripe tissues according to various boiling time period with saucepot or pressure cooker and various ratios of the water to the tripe (wt/wt) were measured. No significant difference was observed in nutrients contents between rumen (1st stomach) and reticulum (2nd stomach) which contained 83% moisture, 0.4-0.5% ash, 3% fat, 13% protein, 50-56 mg% calcium, 75-76 mg% phosphorus. 75-77 mg% ${\alpha}-amino$ N on fresh weight basis. The results obtained show that the significant loss of nutrients observed after removing epitherial cell layer from tripe, and in aspect of the nutrients contents, the nucletides contents, and the sensory evaluation score in soup stock, the optimum cooking time period of tripe was 8 hours in boiling in saucepot and 1 or 2 hours in cooking in pressure cooker, and the ratio of the water to the tripe (wt/wt) was above ten.

  • The effects of the salts fortified with seaweed functional components on blood pressure, serum minerals, and hematochemicals in spontaneously hypertensive rats (SHR/NCrj) and normotensive rats (WKY/NCrj) were investigated. SHR and WKY rats were assigned to four groups, with 8 and 6 rats in each group: laver salt (A), fucoidan+laver high salt (B), fucoidan + laver low salt (C) and refined salt as a control (D). The final blood pressure (BP) of SHR and WKY species in contrast with reference BP were low in groups A and C as compared with control group. In terms of serum mineral content, $Na^+$ levels were similar in SHR and WKY, but $K^+$ levels were higher in the group B in SHR. Serum triglyceride levels were lower in groups A and C, but the levels of HDL- and LDL- cholesterol were significantly higher and lower in group A than those of controls, respectively (p<0.05). These results demonstrated that the salts fortified with laver might suppress blood pressure in rats, and also may improve mineral and lipid metabolism.
