양지원,이종호,김응엽,신동훈,Yang, Jiwon,Lee, Jongho,Kim, EungYeop,Shin, Dong Hoon The Korean Society of Clinical Neurophysiology 2016 Annals of Clinical Neurophysiology Vol.18 No.1
Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron degenerative disease that clinically manifests both upper and lower motor neuron signs. However, it is unknown where and how the motor neuron degeneration begins, and conflicting hypotheses have been suggested. Recent advanced radiological techniques enable us to look into ALS neuropathology in vivo. Herein, we report a case with upper motor neuron-predominant ALS in whom the results of brain magnetic resonance imaging (MRI) and myelin water fraction MRI suggest axonal degeneration.

In this study we report on the estrogen activity of silkworm pupa and herb extracts in vitro. The estrogenic activity of these resources was investigated by competition binding assays with estrogen receptor $\alpha(ER{\alpha})\;or\;ER{\beta}$, and viability of MCF-7 cells, a human breast cancer cell line. Saturation ligand-binding analysis of $ER{\alpha}\;and\;ER{\beta}$ revealed that all plant extracts competed with estrogen ligand for binding to both ER subtypes with a similar preference and degree and competed stronger with ligand for binding to $ER{\beta}\;than\;to\;ER{\alpha}$. The highest $ER{\alpha}-binding$ sample was silkworm pupa aqueous extract The highest $ER{\beta}-binding$ sample was silkworm pupa oil. These samples were further tested for bioactivity based on their ability to regulate cell growth rate in ER(+) breast cancer cell line, MCF-7 cells. Our studies showed that silkworm pupa, soritae, sesame, yam, pueraria, malt, ginseng, Polygonum multiflorum, and Curcuma longa significantly stimulated the growth of MCF-7 cells (P<0.05). In summary, these results suggested that silkworm pupa and herbs might be useful as potential phytoestrogens.

Purpose: Nurungji is a traditional Korean food made by yellowish scorched rice. After getting gelatinization of rice, a thin crust of scorched rice will usually be left in the bottom of the traditional cooking pot. In this study, physicochemical characteristics and antioxidant properties of five commercial nurungji products (CNP1, CNP2, CNP3, CNP4, and CNP5) were evaluated. Methods: Physicochemical properties of the five commercial nurungji products were evaluated with AOAC method. The antioxidant activities were assessed using the 1,1-diphenyl-2-picryl hydrazyl (DPPH), 2,2-azinobis-(3-ethyl-benozothia zoline-6-sulfonic acid)(ABTS), ferric reducing antioxidant power (FRAP), and reducing power assays. Results: Water content was the highest in CNP3, followed by CNP1, CNP2, CNP5, and CNP4. Crude ash content of all nurungji was less than 1%. In Hunter color parameter, the significantly highest a value (redness) and b value (yellowness) were measured in the CNP4 product, meanwhile the lowest in CNP3 (p<0.05). The nurungji products of CNP4 and CNP5 had the significantly higher content in total polyphenols and total flavonoids, compared to those of other products. CNP3 and CNP2 had the lowest in total polyphenols and total flavonoids, respectively. CNP4 and CNP5 products showed the significantly higher values in antioxidant activities, whereas CNP3 had the lowest activity. Conclusion: The high value of antioxidant activities in CNP4 and CNP5 might have been affected primarily by the total polyphenols with increasing browning color during the heat treatment.
Evaluation on the Quality of Fresh, Conventionally Heated and Ohmically Heated Mulberry Fruit Juice

The aim of this study was to establish the superiority of ohmic heating over conventional heating for the sterilization of mulberry juice. Heat treatment of fresh juice significantly reduced the concentration of soluble solids, lowered the pH, and lowered the reducing sugar content (p<0.01). Color measurements showed decreases in the L and a values and increases in the b, H and C values after heat treatment, although the total color differences were smaller after ohmic heating than after conventional heating of fresh juice. The antioxidant capacities, such as reducing power, FRAP, and DPPH, decreased in the order of fresh juice, ohmically heated juice and conventionally heated juice. Furthermore, the anthocyanin, flovonoid, and total antioxidant capacities of the juices significantly decreased in the same order. Sensory evaluations showed no difference between fresh and ohmically heated mulberry fruit juice excluding off-flavor, whereas conventionally heated juice received significantly lower evaluations. The microbial counts were zero in the juice after either heat treatment. Thus, ohmic heat treatment can be effectively used to sterilize fresh mulberry juice to obtain good shelf life with minimal physicochemical, color, antioxidant and sensory deterioration.
한국의 과학기술 어디까지 왔나 - 발효 기술, 아미노산 발효기술 선진국 수준
양지원,Yang, Ji-Won 한국과학기술단체총연합회 2000 과학과 기술 Vol.33 No.10
우리나라의 생명공학기술 수준은 선진국을 100으로 볼 때 65정도로 열세이지만 분야별로 강세를 보여온 발효기술은 90정도로 선진국에 근접해 있으며 특히 아미노산 발효기술은 높게 평가를 받고 있다. 21세기 선도산업으로 꼽고 있는 생물산업의 경쟁력 우위를 점하기 위해선 더 많은 기술적ㆍ경제적인 투자가 절실하다.

The project for recording the unique values and characteristics of the region is increasing due to the reason for applying it to the future planning direction. Although it is a significant project that can examine regional characteristics in human, social and economic ways, it tends to develop gradually in a uniform direction, contrary to its original intention. To address these problems, the need for introducing a regional-specific survey method considering regional characteristics is raised. In addition, In addition, after investigating the local lifestyle, an alternative is needed for the outcome to be actively utilized in the local revitalization plan, and measures are needed for residents to utilize the data. Therefore, the purpose of this study is to propose improvement direction by examining the progress, characteristics and limitations of utilizing results of related projects through case analysis of domestic life-culture recording projects.
