To reuse the waste bone from restaurants or butcher houses, the possibility of using waste bone powder after cooking as a filler for wood adhesives used in manufacturing plywood was investigated. Radiata pine (Pinus radiata D. Don) plywoods were manufactured by using commonly used wood adhesives such as urea-melamine formaldehyde (UMF) resin, urea-formaldehyde (UF) resin, and phenol-formaldehyde (PF) resin and the prepared fillers from cattle bone powder, pig bone powder, and seashell powder. Plywood fabricated by using cattle bone powder, pig bone powder, and seashell powder showed weaker performance in dry and wet glue-joint shear strength and wood failure than those of the plywood with wheat flour. The result showed that it was hard to use only bone powder for the replacement of wheat flour. However, the filler mixed with wheat flour and bone powders showed equivalent dry bonding strength and better water resistance than the wheat flour, indicating that bone powders mixed with wheat flour might be used for the manufacture of plywood. When bone powders were mixed with wheat flour as adhesive fillers the shell powder showed the lowest bonding properties and there was no big difference between the cattle bone powder and the pig bone powder.

This study was conducted to examine the effect of bluefin tuna bone on the bone metabolism of the rats. Weaned 6-week old male rats were fed low-calcium diets for 2 weeks after the adjustment period. Rats were divided into 6 groups and were fed experimental diets for six weeks. Experimental groups were \circled1 Normal calcium: CC (0.5% CaCO$_3$; control) \circled2 TB (bluefin tuna bone powder) \circled3 CT (citrated bluefin tuna bone powder) \circled4 BB (bovine bone powder) \circled5 CL (calcium lactate) \circled6 Low calcium LC (0.15% CaCO$_3$). Low-calcium diet group (LC) showed the lowest calcium retention. There was no differences in calcium excretion in stool and calcium absorption among various calcium sources. Serum calcitonin levels were high in TB, CT and BB group compared to those in CC, CL LC group. Parathyroid hormone and osteocalcin levels showed no differences among experimental groups. Deoxypyridinoline (DPD) levels were significantly higher in LC group than in other groups. Wet weight of the femur were significantly high in TB and CT group, and dry weight of femur showed no differences among normal calcium groups. Bone density of femur in LC group was significantly lower than those of normal calcium feeding group, and TB group showed highest bone density among experimental groups. There was no differences in bone metabolism among various calcium sources. Therefore, it is pointed out that the amount of calcium intake is very important because there was significant differences between normal calcium diet and low calcium diet. According to the results of femur weight, ash, calcium and bone density, it is suggested that bluefin tuna bone have alternative effects to bovine bone powder on the maintenance of bone health.

BACKGROUND: Bone meal is commonly used as a phosphorus (P) fertilizer in organic farming. Effectiveness of bone meal was compared with mineral P fertilizer to elucidate the optimum application rates of bone meal in crop production. METHODS AND RESULTS: The effects of bone meal and fused phosphate on plant growth and P uptake were determined in a pot experiment with maize (Zea mays L.) in a clay loam soil. Bone meal and fused phosphate were applied at 150 and 300 mg $P_2O_5/kg$ soil, and maize was grown for 3 consecutive growth periods of 4 to 5 weeks each. As compared with fused phosphate, total shoot growth of maize per pot was 3-6% lower in bone meal fertilization, and the difference was not significant in the application of 300 mg $P_2O_5/kg$. At the same P application rate, uptake of P by maize plants was 7-9% lower in bone meal treatment. The P use efficiency in bone meal treatments ranged from 11.9-13.6%, equivalent to 73-84% of the efficiency for fused phosphate treatments. CONCLUSION: The equivalence of immediate effectiveness of bone meal as a P fertilizer was at least 90% compared with fused phosphate in the pot experiment with maize. The results indicate that bone meal could be a reasonable alternative to chemical P fertilizers.

Small intestinal submucosa (SIS) had been widely used as a biomaterial without immune rejection responses. SIS sponges prepared by crosslinking with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC). SIS powders dissolved in $3\%(v/v)$ acetic acid aqueous solution for 48hrs and freeze-dried. EDC solution ($H_2O$ : ethanol = 5 : 95) as a crosslink agent was used in concentration of 100mM. In vitro, rat-BMSCs seeded in SIS sponges and induced the osteogenesis for 28 days. We have characterized the osteogenic potential of rat-BMSCs in SIS sponges by alkaline phosphatase activity(ALP), n assay, SEM and RT-PCR for osteogenic phenotype. In SEM, all morphology of SIS sponges was regular and showed interconnected pore structure. By RT-PCR analysis, we observed type I collagen expression. These results demonstrate osteogenic differentiation of rat-BMSCs. In conclusion, we confirmed that the morphology of surface, cross-section, and side of SIS sponges were highly porous with good interconnections between each pores, which can support the surface of cell growth, proliferation, and differentiation. This result indicates that SIS sponge is useful for osteogenesis of BMSCs.

국내에서 널리 쓰이고 있는 각종 농후사료에 대한 일반성분 및 Ca, P함량을 분석했고 또 비타민, 광물질, 아미노산 함량을 분석하기 위하여 46종의 사료에 대한 대표 시료를 분석했던 바 그 결과는 다음과 같다. 1. 옥수수, 밀, 소맥쇄, 미강(抽), 밀기울, 대두박(抽), 아마박(抽), 옥수수글루텐밀, 임박(抽), 채종박(抽), 호마박(抽), 골분, 어분(국산 및 외산), 패분등이 가장 수집빈도가 높았으며 대개의 경우 일반성분 분석치에 있어서는 미국 또는 일본의 그것과 큰 차이는 없었으나 분석시료 내용이 다른 경우에는 같은 사료라도 변이가 심하였다. 2. 분석치에 있어서 같은 사료라 할지라도 함량변이가 큰 것이 많았는데(말분, 소맥쇄, 맥강미강, 박류, 골분, 어분, 패분등) 이것은 수집된 샘플이 동일하지 않았고, 같은 사료라도 물리적 성상이 다르거나(말분등), 이 물의 혼입등<골분, 어분, 박류등>이 있었기 때문인 듯하다. 3. 선발된 46종 사료의 대표 샘플에 대하여 비타민, 광물질, 아미노산함량을 분석했던 결과를 보고하였으나 이것이 단 1회의 분석이었다는 점, 또는 어떤 성분은 분석이 안되었다는 점을 고려하여 장차의 보완 작업에 기대는 거는 바이다.

Herein, we present the results of the analysis of a lacquer coating fragment excavated from 'Daesungdong No.88 tomb of Gimhae'. We observed the fragment with an optical microscope and used scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) as well as Fourier-transform infrared spectroscopy analysis to determine the structure of the lacquer coating and the technique used for coating. The sample was identified as a Moksim Jophy Lacquer. It is made from wood, painted with textile fabric and coated with soil clay. The SEM-EDS analysis revealed residues of bone meal at the bottom part of the sheath layer. The incorporation of bone meal in a lacquer coating layer is one of the characteristics of the Han Dynasty, and was also found in the Nangnang Region and the United Silla Dynasty. Inside the sword sheath is a specific adherent structure of silk fabric, the same type of leguminous plant found in another sword sheath excavated from the Eastern Han-tomb of Xi'an. Results constitute the latest information about lacquer ware found in the southern district of the Korean peninsula. Moreover, the findings shed light on an international relationship with Kumkwan-Kaya where the sword sheath was produced.

The study was compared for growth and yield of cherry tomato (Lycopersicon esculentum var. cerasiforme) crops as affected by various homemade liquid fertilizer (LF), commonly applied in the environmentally friendly farmhouses. LF treatment included UT (untreatment, water), OC (oil cake), BF (bone+fish meal), FA (fish amino meal), SO (sesame oil meal), and SF (starfish). Seasonal pH and EC in SO- and SF-LF rapidly decreased at 30 days after the storage, which were the highest EC of 0.6 - 0.8 dS/m, followed by BF-LF with 0.4 dS/m EC. T-N concentration in LF was the highest on the SF (0.0062%), followed by SO (0.0059%) and BF materials (0.0030%), which were all the great for the K concentration in the LF. P and Ca concentrations were the highest on the FA-LF, with the highest Mg concentration observed on the vegetable SO-LF. Soil EC was the highest on the SF-LF plots of 0.74 dS/m, with no significant differences between the treatments observed on the macro-nutrient concentrations in the soil and leaf. Leaf dry weight, leaf temperature, stem diameter, and plant height were investigated at once per 15 days. UT-LF reduced the leaf dry weight at all the measurement time while the plant height was low at an initial measurement but increased and similar to the other homemade LF treatments at a later measurement. Fruit yield and average fruit weight were the lowest on the UT-LF plots at 75 days after fertigation. Fruit diameter was increased by the BF-LF and SF-LF, with the highest fruit soluble solid contents and fruit coloring observed on the FA-LF. BF-LF maintained high fruit firmness.
