Objectives : Daeganghwal-Tang(DGHT) is one of the prescriptions used for the treatment of rheumatoid arthritis(RA) in oriental medicine. The present study aimed to examine the analgesic effect of DGHT on a rat model of CFA-induced arthritis, and the relations between DGHT-induced analgesia and endogenous nitric oxide(NO) and inducible NO synthase(iNOS)/neuronal NOS. Methods : CFA-induced arthritis model used to test the effect of DGHT was chronic pain model. After the induction of arthritis, rats subsequently showed a reduced stepping force of the affected limb for at least the next 18 days. the reduced stepping force of the limb was presumably due to a painful knee. DGHT dissolved in water was orally administrated. After the treatment, behavioral tests measuring stepping force were periodically conducted during the next 4 hours. Results : DGHT produced significant improvement of stepping force of the hindlimb affected by the arthritis lasting at least 2 hours. DGHT produced the improvement of stepping force of the affected hindlimb in a dose-dependent manner. Both NO production and nNOS/iNOS protein expression which is increased by arthritis were suppressed by DGHT administration. Conclusions : The data suggest 1) that DGHT produces a potent analgesic effect on the chronic knee arthritis pain model in the rat and 2) that DGHT-induced analgesia modulate endogenous NO through the suppression of nNOS/iNOS protein expression.

Purpose: The purpose of this study was to investigate the effect of geometrically different wax pattern shapes and sizes on the castability of Grade2 Cp-Ti (commercially pure titanium). Materials and methods: Total of 40 mesh wax pattern ($61mm{\times}24mm$, 207 grids), ($61mm{\times}17mm$, 138 grids) was cast in this experiment. Depending on the geometrical shape of the wax pattern, 8 groups was organized; Flat, Semicircular, Horse-shoe and V-shape, each consisting 5 samples. Runner-bar sprue was used in all patterns. The number of completely cast grid in wax pattern served as a measure for the castability of comercially pure titanium. Results: The mean value of square count in each group was as followed; 133.20 squares in group SS (96.52%), 132.40 squares in group SH (95.94%), 132.00 squares in group SF (95.65%), 127.60 squares in SV (91.43%), 198.60 squares in group LF (95.94%), 197.80 squares in group LV (95.56%), 196.40 squares in group LS (94.88%), and 188.00 squares in group LH (90.82%). Conclusion: Within the limitations of this study the results indicate that there were no sttistically significant difference in castability of titanium regarding wax pattern shape (P>.05). However, Small size wax patterns were showing the noticeable castability more than Large size pattern.

Purpose: The purpose of this study is to fabricate the new zirconia block (CNU block) and to evaluate fit of core and porcelain veneered zirconia crown. Material and methods: The experimental blocks were fabricated from the commercial ytrria-stabilized zirconia powder (KZ-3YE Type A). The powder was uniaxial pressing and the green bodies were conducted using the Cold Isostatic Pressing. The zirconia blocks were presintered at $1040^{\circ}C$ and the final sintering was performed at $1450^{\circ}C$. The Kavo Everest ZS $blank{(R)}$ (KaVo, Biberach/ $Ri{\beta}$.) was used as a control group. The linear shrinkage of CNU block and Kavo block were compared. Twenty-one cores for porcelain veneered crowns were fabricated with CAD/CAM system ($Everest{(R)}$, Biberach/ $Ri{\beta}$.). Group I; seven cores fabricated from Kavo blocks, Group II; seven cores fabricated from CNU blocks, Group III; seven cores from CNU blocks and porcelain veneering for crowns. All specimens were cemented and sectioned into two planes; diagonal and bucco-lingual. The measurement of the marginal, internal, and occlusal fit was carried out using SEM ($S-4800^{(R)}$) at $30{\times}$. The results were analyzed by one-way ANOVA test. Results: The linear shrinkage of the CNU block and the KaVo block was 19.00% and 20.09%. The marginal gap of cores ($29.67{\pm}6.58{\mu}m$) fabricated from CNU blocks showed significantly smaller than that of the cores of Kavo blocks ($36.84{\pm}7.18{\mu}m$) (P < .05). The internal gaps of the porcelain veneered crowns ($32.23{\pm}6.33{\mu}m$) were larger than those of the other two groups ($37.57{\pm}6.81{\mu}m$ and $38.14{\pm}6.81{\mu}m$). Conclusion: No statistically significant difference was found in between experimental groups and control group. The experimental groups in marginal gap showed significantly smaller than the control group.

The most effective and effective function in vehicle safety is an airbag device. An airbag is a safety device that rapidly inflates to protect the driver or occupants in an automobile accident. The airbag inflates the airbag by generating nitrogen gas when a collision sensor and an electronic control unit detect the amount of impact of the vehicle during a collision and exceed the collision limit. In general, when driving at a speed of about 30 km/h or more, the collision sensor detects and deploys when a strong collision is received from the front or side within 30°. (Each country has different laws and regulations) An airbag is effective in reducing the risk of fatal injury or death in a frontal collision and may not deploy unless a seatbelt is worn as an auxiliary restraint device for a seatbelt. In addition, there are various types of airbags, such as side airbags and curtain airbags, in addition to those mounted on the steering wheel or dashboard. Automotive airbags are manufactured in accordance with the regulations on certification and inspection methods and procedures (Korean Standards, Ministry of Environment Notice No. 2021-118) and the regulations on manufacturing automobile test inspections and procedures (Korean Standards, Ministry of Environment Notice No. 2022-73). You must undergo an authentication test. In order to receive a certification inspection, you must follow the vehicle certification test and inspection work procedures of the Korea Environment Corporation. A similar certification procedure exists internationally. The cost of certification inspection varies depending on the type of vehicle and test items, but generally costs between several million won and tens of millions of won. The certification inspection time varies depending on the condition of the vehicle and the test items, but generally takes several days to several weeks. In the case of verification through a verification environment through Hil, it is difficult to configure the same environment as an actual vehicle crash test. The disadvantage is that the range of motion for simulation of impulse and ACU movement is small, and it is difficult to accurately simulate the numerical or quantitative values desired by the tester. The virtual verification environment is a simulation platform that emulates the automobile SW platform, system, and vehicle dynamics model as a digital twin and can pre-verify SW logic and vehicle functions. Compared to the Hil verification environment, it has the advantage of configuring an environment identical to reality and being able to verify by simulating shock amounts and ACU movements at a level similar to reality. Through this, time and cost savings can be expected as mentioned above.

조선후기 서화시장을 통해 본 명작(名作)의 탄생과 위작(僞作)의 유통

徐胤晶 ( Seo Yoon-jung ) 성균관대학교 대동문화연구원 2020 大東文化硏究 Vol.109 No.-

본 논고는 명작의 탄생과 그 사회 문화적 의미를 조선후기 18세기 서화 애호 풍조와 僞作의 의미와 상징성을 통해 살펴보는 것을 목표로 한다. 명작은 畵品을 나누어 그림의 우열을 논하고 화가를 品評하는 동양 특유의 畵論의 전통과 그 맥을 같이 하고 있으며, 위작의 등장은 미술품의 소장과 미술 시장을 전제로 한다. 명말의 尙古主義적인 경향의 중국 예술 서적의 수입과 중국 골동서화의 수입은 조선후기 고동 서화 수집 및 감상의 풍조를 유행 시켰고, 이와 더불어 경제력을 바탕으로 급부상한 상인 계층이 서화 시장의 새로운 고객층으로 급부상함으로써 이전과는 비교할 수 없는 서화에 대한 폭발적인 수요를 불러일으켰다. 그러나 경제적인 구매력을 갖춘 고객층의 등장으로 인한 서화에 대한 폭발적인 수요와는 별도로, 한정적인 서화로 인해 조선 후기에 수많은 위작이 제작, 유통되어 사회적인 문제가 되었다. 이 논문은 위작의 제작과 유통을 동아시아의 서화 제작 관습과 서화의 유통이라는 관점에서 살펴보고, 이를 탐구하기 위해 위작의 기준작으로서 명작의 조건을 분석하고 위작과 진작을 구분하는 감정과 감평에 관해 기록한 화론서에 내용을 제시하고자 한다. 이를 통해서 위작과 위작 연구의 두 가지 가치를 재조명 하고자 한다. 첫째는 위작이 내포하는 다층적인 역사적 시간성이며, 두 번째는 명작 혹은 정전(canon)을 중심으로 기술 될 때 야기될 수 있는 단선적인 역사서술에서 벗어나 다양한 가능성을 제시하며 미술사의 지평을 넓힐 수 있다는 점이다. Focusing on fake paintings in tandem with the culture of collecting and appreciating art in the late Chosŏn dynasty, this essay investigates the process in which works of art achieved masterpiece status and their socio-cultural meanings. In premodern East Asia tradition, theoretical treatises on art use evaluation system to determine the quality of painters or paintings, which affects the establishment of masterpieces. Meanwhile, forgeries emerged as the art market, and collectors appeared. Late Ming antiquarian books and imported ancient works of art stimulated Chosŏn elites' interests in collecting and appreciating antiques and works of art. Besides, the rise of the nouveaux riches, who became the important clientele of the art market in the late Chosŏn used their increased financial resources to purchase works of art. The rise of the value of masterpieces thus touched off increased production of imitation, fakes, forgeries of ancient paintings. This study explores the production and circulation of forgeries from the non-Eurocentric perspective embedded in the premodern East Asian Society. To do so, I examine how we define masterpiece or canon and how these are used to make fakes. A close look at artistic treatise dealing withing appreciating art and connoisseurship is further provided. In sum, I hope this essay show two values of forgery and the study of forgery. First, it reveals the multiple historical temporalities, and second, it broadens the horizons of art history research by providing various possibilities and alternatives, which would have long been lost in the conventional writing of art history centering canon and masterpiece.

감추기와 드러내기 ― 젠더적 관점에서 본 조선시대 서화와 한글 텍스트

徐胤晶 ( Seo Yoonjung ) 성균관대학교 대동문화연구원 2022 大東文化硏究 Vol.118 No.-

조선시대 전통 서화의 영역에서 여성 書畵家 활동의 비가시성(invisibility)과 서화의 제찬과 제시에 보이는 한글의 비가시성은 서로 관련되어 있다. 그 자체로 젠더화된 체계인 ‘書畵’의 영역과 가부장적 한문중심의 유교사회에서 문화와 예술의 생산과 소비에 성(性)의 개념이 어떤 영향을 미치는지, 한자와 한문이 갖는 젠더적 속성이 이미지와 결합될 때 어떤 효과를 발휘하는지, 작품의 제작과 감상에 남성/성과 여성/성이 어떻게 작동하는지 등 조선시대 서화의 후원과 제작과 감상, 수장 전반에 걸쳐 젠더 이데올로기의 작동 방식을 구체적 사례를 통해 고찰해보고자 한다. 본 논고는 여성 작가의 정체성에 대한 이해를 바탕으로 조선이라는 상층 남성 중심의 신분질서와 젠더적 질서로 위계화된 사회에서 하위주체의 여성이 회화와 문자(한글)를 통해 남성화된 서화의 세계―한문의 영역으로 소통되는―에 어떻게 침범하며 동화 또는 소외되는 지에 대해 분석하고자 한다. 이는 조선시대 서화 영역의 젠더성과 여성의 서화 활동을 젠더적 관점에서 고찰하고, 조선시대 시각문화 속에서 한글 텍스트의 출현과 한글 사용을 둘러 싼 젠더적 관점을 제시하고자 하는 시도라고 할 수 있다. 궁극적으로 젠더 연구가 조선시대 미술사에 어떤 기여를 할 수 있는지, 개념적으로 또는 방법론적으로 어떤 의미 있는 질문을 던질 수 있는지에 대한 시론이기도 하다. This study tackles the invisibility of female artists and the absence of the inscription of vernacular texts on works of art in the Joseon dynasty. This essay discusses women’s contributions as artists, patrons, and viewers while exploring how their gendered positions and roles impacted their creation’s production, appreciation, and value. Despite the social restriction and gender discrimination against women within a male-domination society, women found meaningful places in their social order and sustainable ways to retain a sense of self-identity and exert their agency. Through a thorough examination of visual materials revealing women’s active participation, this essay demonstrates how Hangeul, the Korean vernacular alphabet, was used as a versatile tool to uncover women’s contribution to culture as artists, patrons, and consumers. In particular, the genre of calligraphy and painting were typically male-centered as women were not allowed to access formal learning and were discouraged from engaging in literati activities. Yet, considerable powerful and talented female patrons and artists ventured into the male-dominated world of arts and established new areas of art, such as Buddhist paintings and embroidery, through which they revealed their voice, agency, and power.

Objectives: Daeganghwal-Tang(DGHT) is one of the prescriptions used for the treatment of rheumatoid arthritis(RA) in oriental medicine. The present study aimed to examine the analgesic effect of DGHT on a rat model of CFA-induced arthritis, and the relations between DGHT-induced analgesia and endogenous nitric oxide(NO) and inducible NO synthase(iNOS)/neuronal NOS. Methods: CFA-induced arthritis model used to test the effect of DGHT was chronic pain model. After the induction of arthritis, rats subsequently showed a reduced stepping force of the affected limb for at least the next 18 days. The reduced stepping force of the limb was presumably due to a painful knee. DGHT dissolved in water was orally administrated. After the treatment, behavioral tests measuring stepping force were periodically conducted during the next 4 hours. Results: DGHT produced significant improvement of stepping force of the hindlimb affected by the arthritis lasting at least 2 hours. DGHT produced the improvement of stepping force of the affected hindlimb in a dose-dependent mariner. Both NO production and nNOS/iNOS protein expression which is increased by arthritis were suppressed by DGHT administration. Conclusions: The data suggest 1) that DGHT produces a potent analgesic effect on the chronic knee arthritis pain model in the rat and 2) that DCHT-induced analgesia modulate endogenous NO through the suppression of nNCS/iNOS protein expression.
