본 연구는 바나나 첨가에 따른 식빵의 품질 특성을 알아보고자 하였다. 반죽의 mixograph와 stickiness, 발효율, TPA, 비용적, 영상분석, 색도, 수분함량, 기호도 검사를 통하여 분석하였다. Mixograph의 peak time(min)는 모든 시료가 4~5분을 나타냈지만, peak value(%)의 경우 CON, B10, B20 시료가 60% 이상, B30, B40이 60% 이하를 나타냈다. Stickiness 측정결과, 바나나 첨가량이 늘어나면서 점착력이 낮아짐을 알 수 있었다. 발효율은 전반적으로 증가하였으나, B40 시료의 경우 75분 이후에는 감소하는 경향을 보였다. 껍질과 속질의 색도 측정결과, 명도 L값은 CON이 가장 높았고, 적색도 a값은 B40이 가장 높았으며, 황색도 b값 역시 B40이 가장 높았다. pH 측정 결과, B40이 가장 낮은 수치를 보였고, 바나나 첨가량이 많을수록 pH가 낮아지는 경향을 보였다. 바나나 첨가가 제품의 부피와 비용적에는 부정적인 영향을 끼치는 것을 알 수 있었으며, crumbScan을 통한 영상분석 결과, 껍질두께, 기공의 찌그러짐에서 유의한 차이는 나타나지 않았다. 반면, 기공의 조밀도에서는 CON의 값이 774.33으로 가장 낮았으며, B40의 값이 927.66으로 가장 높게 나타났다. Hardness는 유의한 차이를 보이며 B40이 가장 낮았고, 대조구가 가장 높았다. 수분함량은 전체적으로 유의한 차이가 있었고, CON의 값이 가장 높았으며, 바나나 첨가량이 늘어남에 따라서 그 값이 줄어드는 것을 확인할 수 있다. 관능검사 중 기호도 검사 결과, B20이 가장 높은 평가를 받았고, B40은 전체적 기호도에서 가장 좋지 않게 나타났다. 특성차이 검사결과, 바나나 첨가량이 부피를 크게 하는데 부정적인 영향을 끼친다는 것을 확인할 수 있었다. 전반적인 품질특성 결과와 관능검사 결과에 따르면, 바나나를 20% 첨가하는 것이 품질과 기호도 측면에서 최적이라 사료된다.

One of the main processes of tenderizing beef in Joseon Dynasty was chemical methods involving Apricot seeds, manchu cherry twig and leaves, bamboo skins, mulberry tree bark, mangsa (硭砂), salmiacum (磠砂), alcohol, fermented malt, and original honey. This study analyzed and compared the effect of broussonetia papyrifera, fermented malt, cherry trees, and mulberry tree bark from old cookbooks. Tenderizing beef with cherry trees was most effective in the experiment on shearing force, TPA, and electrophoresis of beef. According to sensory evaluation and electrophoresis test results, tenderized beef with mulberry tree bark was slightly more preferred over the method using cherry trees. However, in accordance with the above mentioned experiment, quantitative descriptive analysis showed that the most common tenderizing material was derived from morus alba powder.

The process of transcription is the major point at which gene expression is regulated. The jun and fos families of eukaryotic transcription factor heterodimerize to form complexes capable of binding 5'-TGAGTCA-3'DNA elements (AP-1 binding site). To search for the inhibitors of the jun-fos-DNA complex formation, several natural products extracts were screened and methanol extract of tanshen (the dried roots of Salvia miltiorrhiza Bunge) showed remarkable inhibitory activity. The active compounds of the extracts were purified using re-peated column chromatography and recrystallization. Their structures were identified as tanshinone I and tanshinone IIA. Through the electrophoresis mobility shift assay and cell cytotoxicity test, tanshinone I and tanshinone IIA were identified as inhibitors that suppress not only AP-1 function but also the cell proliferation. Tanshinone I also suppressed the jun-fos-DNA complex formation in TPA-induced NIH 3T3 cells.

녹두전분, 동부전분, 옥수수전분 등 3종류의 전분을 증류수 또는 오미자추출액에 분산시켜 겔을 제조하여(각각 전분젤리, 오미자젤리라 칭함) RVA에 의한 점도특성, 겔의 색도, 이수율, 파단특성 및 TPA특성의 텍스쳐특성을 조사하고, 관능검사를 실시하였다. 점도특성은 오미자추출액분산 전분현탁액의 호화온도가 세 전분 모두 상승하여 오미자추출액이 호화를 지연시키는 것으로 나타났으나 최종점도가 저하하여 전분의 결정화가 억제되는 것으로 나타났다. 또한 동일 농도에서 비교하면 세전분 중에서 옥수수전분의 점도치가 가장 낮아서 녹두, 동부전분보다 더 높은 농도로 사용해야함을 나타내었다. 색도는 옥수수전분겔의 L값이 가장 높아 백색도가 가장 높은 것을 나타내었으며, 이수율은 오미자젤리의 이수율이 전분젤리보다 저하하여 오미자추출액이 전분겔의 안정성을 높여주는 것을 나타내었다. 텍스쳐 특성은 오미자 젤리는 파단응력, 파단변형 등의 파단특성이 전분젤리보다 감소하여 오미자추출액에 의해 겔이 약화되고 탄력성이 적은 겔로 되며, 부착성이 커져서 끈적임이 커지는 것을 나타내었다. 옥수수전분의 오미자젤리는 응집성이 낮으면서 부착성이 커서 풀과 같은 텍스쳐를 나타내었다. 관능적 특성은 기계적 특성과 대체로 일치하는 경향이었으며, 전반적 바람직성은 녹두전분 7, 8%, 동부전분 8, 9%에서 높았으며 옥수수전분은 모든 농도에서 전반적 바람직성이 떨어졌다. 이상의 결과로 오미자젤리 제조시 녹두전분 사용시는 7, 8%, 동부전분 사용시는 8, 9%의 농도가 적당하며, 옥수수전분 사용시는 텍스처를 개선시킬 수 있는 방도가 필요하다고 생각되었다.

As a matter of fact, it has been not allowed to modify the shape of a vehicle body skeleton since the technical definition for the structure was fixed and the corresponding molds were developed. By the way, if it is available to apply an alternative to reinforce the skeleton without changing its mold, it must be much flexible to improve the performance qualities relevant to not only NVH(noise, vibration and harshness) but also crash and durability. Recently, a solution of so-called composite body becomes available for the need. We present a design method to insert the composite body inside a vehicle body skeleton in order to improve a structure-borne noise at the idle condition. The algorithms, topology optimization and design sensitivity analysis, are applied to mainly search the sensitive structural sections in the body skeleton and to extract the target stiffness of the sections. Inserting the composite bodies into the sensitive portions, it is predicted to achieve the countermeasures which can compromize the design availability in terms of the idle noise and weight. According to the validation result with test vehicles, the concerned noise transfer function is reduced and the idle booming noise is resultantly improved.

This paper presents a the method for estimating the noise source contribution on the road noise of the vehicle in a multiple input system where the input sources may be coherent with each other. By coherence function method, it is found that the biggest part of the noise source in the road noise is generated by structural vibration on the mechanical-acoustic transfer functions of vehicles. This analysis is modeled as four input/single output system because the noise is generated with four wheels that mechanism of the road noise is very complicated. The coherence function method is proved to be useful tool for identifying of noise source. The overall levels of the interior noise be coherence function method are compared with those measured and calculated by the frequency response function approach using mechanical excitation test. The experimental results have shown a good agreement with the results calculated by the coherence function method when the input sources are coherent strongly each other. The estimation of the road noise indicates that significant coherent can be achieved in the vehicle interior noise.

Eleven polyhydroxyursane triterpenoids (PHUTs) were tested to determine their cytoprotective, immunosuppressive and anti-inflammatory effects. To compare the bioactivities of $19{\alpha}$-hydroxyursane-type triterpenoids {23-hydroxytormentic acid (6), its methyl ester (7), tormentic acid (8), niga-ichigoside $F_1$ (9),euscaphic acid (10) and kaji-ichigoside $F_1$ (11)} of the Rosaceae crude drugs (Rubi Fructus and Rosa rugosae Radix) with PHUTs possessing no $19{\alpha}-hydroxyl$ of Centella asiatica (Umbelliferae), the four PHUTs, asiaticoside (1), madecassoside (2), asiatic acid (3), and madecassic acid (4) were isolated from C. asiatica and 23-hydroxyursolic acid (5) from Cussonia bancoensis. Cytoprotective effects were assessed by measuring cell viabilities against cisplatin-induced cytotoxocity in $LLC-PK_1$, cells (proximal tubule, pig kidney) to determine whether these agents have protective effects against nephrotoxicity caused by cisplatin. The inhibitory effect of 11 PHUTS on nitric oxide (NO) and prostaglandin $E_2\;(PGE_2)$ were evaluated by measuring nitrite accumulation in lipopolysaccharide (LPS)-induced macrophage RAW 264.7 cells, and their anti-inflammatory effects were tested in 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced mouse ear edema model. Six MHUTs (compounds 1, 2, 4, 6, 10, and 11) exhibited higher cell viabilities during cisplatin-induced cytotoxicity testing even at a concentration of $200\;{\mu}g/ml$ than cisplatin only-treated group, suggesting that ese compounds have the potentcytoprotective efffcts. Compounds 1 and 3 of the C. asiatica and niga-ichigoside $F_1$ exhibited no inhibitory effect on NO and/or $PGE_2$ production whereas other PHUTs produced mild to significant NO and/or $PGE_2$ production.The four compounds (2, 5, 9, and 10) potently inhibited mouse ear edema induced by TPA whereas two compounds (1 and 3) had no activity in this test. These results suggest that many PHUTs are potentchemopreventives. Structure-activity relationship (SAR) was also discussed in each assay with regard to the significant role of OHs at the position of 2, 3, 6, 19, and 23 and to the glycoside linkage at the 28-carboxyl.
