Yoon Sil Choi,Me Suk Kim 한국체육철학회 2014 움직임의철학 : 한국체육철학회지 Vol.22 No.1
Yeonsangun(燕山君) gathered the court dancers and named them ‘Heung cheong’ in 1504. The researcher, Yoon-Sil Choi who learned the techniques of Gyobangdance(敎坊舞) from Su-Ak Kim, composed a new dance ‘Heungchungmu(興淸舞)’ which expressed the lives of Heungcheong, based on Gyobangdance(敎坊舞). Choi also founded ‘Heungchungmu(興淸舞) Preservation Institute’. Heungchungmu(興淸舞) Preservation Institute strives to preserve Heungchungmu(興淸舞) by establishing branches in the following areas: starting from Seoul, Jeju, Kyong-gi, North Jeonla, South Jeonla, North Chungcheong and South Kyungsang; and by constantly performing in National Gugak Center and rural areas. There has been no studies on Heungchungmu(興淸舞), thus it is required to conduct research on the subject in order to properly pass down Heungchungmu(興淸舞). The purpose of this paper is to provide academic basic data in order to succeed and develop Heungchungmu, and continuously research the social and cultural preservation value of it. This study discusses the origin, dance motions, music, traditional clothing and accessories, and artistic features of Heungchungmu(興淸舞). To conclude, Heungchungmu(興淸舞) has the intrinsic characteristics of Gyobangdance(敎坊舞), hence may be a sole solution to succeeding Gyobangdance(敎坊舞) accurately. Moreover, it is necessary to designate the dance as Important Intangible Cultural Properties of Korea and get politic support for development and succeed of Heungchungmu(興淸舞).

거미줄곰팡이인 R. oryzae N174를 이용한 액체종국 배양기술을 개발하기 위해, 밀기울 농도별(0, 5, 10, 15 및 20%)로 액체종국을 제조하여 이들의 품질 특성을 조사하였다. 배지에 밀기울 첨가량이 많을수록 균사체량이 많아졌을 뿐 아니라 산도, 아미노산도가 증가하는 특성을 보였다. 또한, 밀기울을 5% 첨가한 군에서 α-amylase와 glucoamylase의 활성도가 높았으며 acidic protease의 경우에는 15% 밀기울 첨가 배지에서 활성도가 높았다. 배양시간 별(0, 24, 48, 72 및 96 hrs) 효소 활성은 48~72시간에 효소활성이 가장 높은 것으로 나타났다. R. oryzae N174 액체종국 최적조건은 5~15% 밀기울 배지에서 48~72시간 배양이 최적조건이었다. 이를 토대로 밀기울 액체종국을 제조하여 저장온도와 저장기간을 달리하여 저장한 후, 밀누룩 제조시 종국으로서 적합한지를 구명하고자 하였다. 제조된 밀누룩의 효소 활성뿐만 아니라 pH, 산도 및 환원당 함량을 비교 분석한 결과, 저장온도와 상관없이 하루 정도 저장한 액체종국을 사용하여 만든 밀누룩에서 높은 수치를 보였다. 저장조건에 따른 형태학적 변화를 살펴본 결과, 저장된 액체종국에서 균사체의 생육과 포자의 생성유무에 따라 밀누룩의 효소 활성에 영향을 미칠 것이라는 예상과는 달리 각 효소의 활성과 균사체의 생장, 포자의 생성과는 큰 차이가 보이지 않았다. Production of liquid starters using wheat bran as a medium for Rhizopus oryzae N174 and the changes in their characteristics noted during storage were investigated in this study. The optimal culture conditions of the liquid starters were determined to be 5~15% (w/v) wheat bran and 48~72 hrs of incubation. The effects of liquid starters with different storage periods and temperatures (-18, 4, 10 and 25oC) on the quality of wheat nuruk were evaluated. According to the results of the pH, acidity, reducing sugar and enzyme activities, it was found that liquid starter using wheat bran preserved for one day, at any temperature, is the best method of storage for seed cultures for R. oryzae N174.

This study focus was primarily the development of liquid starters for Aspergillus oryzae and Aspergillus niger prepared with wheat bran as a low cost culture medium. For the preparation of the liquid media wheat bran was added at rates of 0, 5, 10, 15 and 20% and the Aspergillus sp. strains were then inoculated to these prepared broths. The results indicated that the more that wheat bran was contained in the medium, the more mycelia was produced for A. oryzae and A. niger. The highest enzyme activities were obtained with a 10~15% adding rate of wheat bran for both strains. Changes in the enzyme activities of the liquid starters during various incubation times (0, 24, 48, 72 and 96 hrs), indicated that the highest enzyme activities were seen between 48 and 72 hrs of culture. In addition, a comparative study was carried out on the production of enzymes using wheat as a substrate in nuruk, with liquid starter made from fermented agents according to the same concentrations used with the wheat bran. The pH, acidity, amino acidity, reducing sugar content and enzyme activity (α-amylase, glucoamylase, acidic protease) of wheat nuruk made with liquid starter were compared with those of wheat nuruk made with solid starter. The results suggest that the liquid starter is superior in both cases.

This study was conducted not only to investigate the effects of rate of addition of dried jujube to Yakju but also to examine the quality changes in jujube Yakju during its storage. The results showed no significant differences in pH, total acidity, soluble solids, and anthocyanin and alcohol contents of the Yakju right after its fermentation. With the increase in the amount of jujube that was added, the lightness of the jujube Yakju changed from 93 to 94, its redness decreased, and its yellowness significantly increased. The jujube Yakju that was fermented with 1.5-percent dried jujube had high sensory evaluation scores for color, flavor, taste and overall acceptability. It had no significant changes in pH and total acidity during its storage after its heat treatment. Its soluble solids contents tended to decrease with its heat treatment and to increase in its storage period. With respect to its color changes during its storage, the higher the ratio of the jujube that was added, the longer the storage period was, the lightness and redness decreased and the yellowness increased. The polyphenol contents depended on the rate of addition of the dried jujube, but were not affected by the heat treatment and storage period. The organic acids in jujube yakju were citric acid, succinic acid, lactic acid, malic acod amd aceyoc acod.

<P>This study reports disordered antireflective subwavelength structures (SWS) on GaN and indium tin oxide (ITO) surfaces fabricated using thermally dewetted Ag nanoparticles. It is shown that the average diameter of Ag nanoparticles, which determines the optical characteristics, can be simply controlled by changing the thickness of the Ag thin film and the annealing temperature. The fabricated GaN and ITO SWS with tapered profile exhibited very low reflectance compared to that of a flat surface over a wide wavelength range.</P>
Immediate Effects of Soft Tissue Massage on Posterior Shoulder Muscle Tightness: A Preliminary Study
( Sil Ah Choi ),( Ji Hyun Lee ),( Tae Lim Yoon ),( Heon Seock Cynn ) 한국전문물리치료학회 2012 한국전문물리치료학회지 Vol.19 No.4
Posterior shoulder muscle tightness is frequently observed in shoulder impingement syndrome because tightness in the posterior portion of the shoulder muscles can cause anterior and superior translation of the humeral head in relation to the glenoid fossa. The purpose of this study was to determine the immediate effects of soft tissue massage on acromiohumeral distance (AHD), anterior translation of the humeral head, and glenohumeral (GH) range of motion (ROM) in subjects with posterior shoulder muscle tightness. Twenty-seven subjects with greater than 10° difference in the range of GH horizontal adduction between right and left sides were recruited. The range of GH horizontal adduction and internal rotation were measured by a digital inclinometer. The AHD and anterior translation of the humeral head were measured using ultrasonography. A paired t-test was used to compare AHD, anterior translation of the humeral head, and the range of GH horizontal adduction and internal rotation before and after soft tissue massage. The results showed that AHD increased significantly (p<.05) and the anterior translation of humeral head decreased slightly, but not significantly (p=.40) after the soft tissue massage. Furthermore, the ROM of horizontal adduction and internal rotation in the GH joint increased significantly after the soft tissue massage (p<.05). These findings indicate that soft tissue massage on posterior shoulder muscle tightness is an effective method to increase AHD and ROM in the horizontal adduction and internal rotation of the GH joint.

We employed human SK-MEL-28 cells as a model system to identify cellular proteins that accompany N-(4-methyl)phenyl-O-(4-methoxy)phenyl-thionocarbamate (MMTC)-induced apoptosis based on a proteomic approach. Cell viability tests revealed that SK-MEL-28 skin cancer cells underwent more cell death than normal HaCaT cells in a dose-dependent manner after treatment with MMTC. Two-dimensional electrophoresis in conjunction with matrix-assisted laser desorption/ionization-time of flight (MALDl- TOF) mass spectrometry analysis or computer matching with a protein database further revealed that the MMTC-induced apoptosis is accompanied by increased levels of caspase-1, checkpoint suppressor-1, caspase-4, NF-κB inhibitor, AP-2, c-Jun-N-terminal kinase, melanoma inhibitor, granzyme K, G1/S specific eye/in D3, cystein rich protein, Ras-related protein Rab-37 or Ras-related protein Rab-13, and reduced levels of EMS (oncogene), ATP synthase, tyrosine-phosphatase, Cdc25c, 14-3-3 protein or specific structure of nuclear receptor. The migration suppressing effect of MMTC on SK-MEL-28 cell was tested. MMTC suppressed the metastasis of SK-MEL-8 cells. It was also identified that MMTC had little angiogenic effect because it did not suppress the proliferation of HUVEC cell line. These results suggest that MMTC is a novel chemotherapeutic and metastatic aoents aqainst the SK-MEL-28 human melanoma cell line.
