본 연구는 ‘내향성 발톱 교정에 관한 사례 고찰 연구’로서 보다 효과적인 내향성 발톱 교정 방안을 제안하고자 함에 있다. 고찰하여 분석한 결과 배민규, 윤천성(2022)은 내향성 발톱 예방 및 개선⋅교정을 목적으로 활용한 레진 젤(크랄레젤)을 활용한 내향성 발톱 교정 방법이 제품 활용 편리성, 문제점 등에서 다른 연구자들의 연구방법에 따른 문제점 등과 비교했을 때 활용 가치가 있을 것으로 판단했다. 다만 기존 다른 연구자들의 아크릴 스캅춰, Brace System, 실크, 와이어 등 제품들에 비해 교정 효과가 비교적 낮아 김경환(2022) 연구자가 내향성 발톱 교정 효과성 검증을 위해 활용했던 견인기를 함께 활용하기를 제안한다. 내향성 발톱 예방 및 재발 방지를 목적으로 배민규, 윤천성(2022) 연구자가 제안한 크랄레젤 리커버 1회 적용을 제안하고, 내향성 발톱 개선 및 교정을 목적으로 김경환(2022) 연구자가 활용한 견인기를 활용하여 발톱을 펴준 후, 배민규, 윤천성(2022) 연구자가 제안한 크랄레젤 리커버를 목적에 맞게 2~5회 적용하여 활용하기를 제안한다. 본 연구 자료가 내향성 발톱 질환으로부터 건강한 삶을 영위하기 위한 자료로 활용될 수 있기를 기대해 본다. As “a case study on the correction of ingrowing nail”, this study aims to suggest more effective measures for the correction of ingrowing nail. In the results of considering and analyzing it, the correction of ingrowing nail using the Resin Gel(Kralle Gel) which was used by researchers Min-Gyu Bae & Chun-Sung Youn(2022) for the purpose of preventing, improving, and correcting the ingrowing nail, seemed to be more useful than other methods used by other researchers in the aspect of convenience of product use and problem. However, compared to the products like Acrylic Sculpture, Brace System, Silk, and Wire used by other researchers, the effect on correction was relatively lower, so it is proposed to be used together with the Retractor that was used by Kyeong-Hwan Kim(2022) for verifying the effectiveness on the correction of ingrowing nail. This study suggests applying Kralle Gel Recover one time suggested by Min-Gyu Bae & Chun-Sung Youn(2002) for the purpose of prevention & recurrence prevention of ingrowing nail, unbending the nail by using the Retractor used by a researcher Kyeong-Hwan Kim(2022) for the purpose of improving/correcting the ingrowing nail, and then applying Kralle Gel Recover 2-5 times suitable for the purpose, suggested by researchers Min-Gyu Bae & Chun-Sung Youn(2022). The results of this study are expected to be utilized as the data for enjoying a healthy life from ingrowing nail disease.

The purpose of this study was to evaluate effects of Cordyceps militaris on fat oxidation during submaximal exercise. Fifteen healthy male collegiate students(ingestion group, N=7; control group, N=8) participated as subjects after signing an informed consent following overnight, subjects completed maximal graded execise test on treadmill to determine exercise intensity(50%VO2max). To evaluate the fat oxidation using indirect calorimeter, it was performed submaximal treadmill to determine exercise lasting. 40min at 50%VO2max after 5day and consumed Cordyceps militaris on separate days. This study was used 2×4 two way repeated ANOVA to analyze physiological and metabolic variables between two groups and metabolic variables between two groups and four exercise periods(l0min, 20min, 30min 40min), and used Scheffe to post-hoc test. Significance was set at α=.05. The results of this study were as followed: First, there were significantly highest in ingestion group for V02, percentage of fat oxidetion(%fat), fat per kilocarolies(Fkcal), and total per kilocarolies(Tkcal)(p<.05), but respiratory exchange ration(RER) and heart rete(HR) were significantly lower in ingestion group(p<.05). Second, RER, %fat, Fkcal were significantly difference in 10, 20, 30, 40min of exercise period(p<.05). This results suggest that there is the effect of Cordyceps militaris on fat oxidation submaximal exercise. Additionally, to evaluate effect of Cordyceps militaris as ergogenic aid, it should be required the future study that included extend subjects, various dosage, and chronic consumption.

본 연구에서는 가압가열 및 microwave 처리가 gliadin의 항원성에 미치는 영향을 살펴보기 위해 중력분에 가압가열과 microwave를 단독 또는 병행으로 처리하여 Ci-ELISA, SDS-PAGE 및 immunoblotting을 실시하였다. 가압가열 처리의 경우, 처리 시간이 길어질수록 IgG와의 결합력이 감소하였으며, 특히 50분 처리구에서 약 69%로 가장 낮은 결합력을 보였다. 또한 SDS-PAGE와 immunoblotting 결과에서도 무처리구에서 강하게 보였던 gliadin band가 처리에 의해 거의 소실되고 항체와 반응하지 않았다. 가압가열 및 microwave를 병행 처리한 경우도 마찬가지로 gliadin의 결합력이 다소 감소하였으며, 처리구 중에서는 가압가열 50분, microwave 5분 처리구에서 약 73%로 가장 낮은 결합력을 보였다. 반면 microwave를 단독으로 처리하였을 때에는 일부 단백질의 변화는 관찰되었으나 항원성 감소에는 큰 영향을 미치지 않았다. 이상의 결과를 통해 가압가열을 단독 처리에 의해 gliadin의 항원성이 다소 감소되었으며, microwave 병행 처리에 의한 차이는 크게 나타나지 않은 것을 확인하였다. This study was conducted to evaluate the effect of physical treatments on the antigenicity of gliadin in medium wheat flour. The wheat flour was treated with an autoclave (5, 10, 30, 50 min), a microwave (1, 5, 10 min), and both (10, 30, 50 min/ 5, 10 min), and investigated by SDS-PAGE, immunoblotting and Ci-ELISA using anti-gliadin IgG. The results showed that the binding ability of anti-gliadin IgG to gliadin in wheat flour was slightly decreased when autoclaved or when autoclaved and microwaved. Especially, it was reduced to about 69% after autoclaving for 50 min and 73% after autoclaving for 50 min and microwaving for 5 min. In addition, gliadin bands in the 50 min autoclaved group disappeared in both SDS-PAGE and immunoblotting. On the other hand, the antigenicity of gliadin was unaffected by microwaving alone. Consequently, there were no considerable changes in using an autoclave alone or in combination with a microwave. These results suggest that autoclaving may affect the reduction of the antigenicity of gliadin in medium wheat flour.

Radicicol Inhibits iNOS Expression in Cytokine-Stimulated Pancreatic Beta Cells

Youn, Cha Kyung,Park, Seon Joo,Li, Mei Hong,Lee, Min Young,Lee, Kun Yeong,Cha, Man Jin,Kim, Ok Hyeun,You, Ho Jin,Chang, In Youp,Yoon, Sang Pil,Jeon, Young Jin The Korean Society of Pharmacology 2013 The Korean Journal of Physiology & Pharmacology Vol.17 No.4

Here, we show that radicicol, a fungal antibiotic, resulted in marked inhibition of inducible nitric oxide synthase (iNOS) transcription by the pancreatic beta cell line MIN6N8a in response to cytokine mixture (CM: TNF-${\alpha}$, IFN-${\gamma}$, and IL-$1{\beta}$). Treatment of MIN6N8a cells with radicicol inhibited CM-stimulated activation of NF-${\kappa}B$/Rel, which plays a critical role in iNOS transcription, in a dose-related manner. Nitrite production in the presence of PD98059, a specific inhibitor of the extracellular signal-regulated protein kinase-1 and 2 (ERK1/2) pathway, was dramatically diminished, suggesting that the ERK1/2 pathway is involved in CM-induced iNOS expression. In contrast, SB203580, a specific inhibitor of p38, had no effect on nitrite generation. Collectively, this series of experiments indicates that radicicol inhibits iNOS gene expression by blocking ERK1/2 signaling. Due to the critical role that NO release plays in mediating destruction of pancreatic beta cells, the inhibitory effects of radicicol on iNOS expression suggest that radicicol may represent a useful anti-diabetic activity.

Correlative changes between photosynthetic O_2 exchange rates and room temperature Chl fluorescence were investigated in wheat (Triticum aestivum L.) chloroplasts treated with high temperature for 5 min. With increaseing treatment temperature, photosynthetis O_2 evolution rate mediated by PSⅡ was decreased, showing 50% inhibition at 38℃ (Ⅰ_50). But PSⅠ activity measured by O_2 uptake rates was stimulated as a function of increasing temperature. Dark level fluorescence (Fo)-temperature (T) analysis showed that florescence rising temperature( T_r), critical temperature (T_c), and peak temperature (T_p) was 38, 43, and 52℃, respectively. Quenching analysis of Chi fluorescnece showed that both the oxidized fraction of plastoquinone (qQ) and the degree of thylakoid membrane energization (qNP) increased up to 40℃ and then declined dramatically. These results suggest that T_r is correlated with temperature showing a 50% inhibition of photosynthesis and under mild high temperature stress, qNP is worth regarding as indicator for heat-induced damage of photosynthesis.

화장품 광고에 나타난 베이스메이크업 질감 트렌드분석 - 2006-2013년 국내브랜드를 중심으로 -

With the craze to look younger in the modern society, women express their ego and the desired integrated image of themselves through the usage of base make-up, which determines the texture of skin. The images they aspire to are often influenced by media, such as how female actors and idol stars wear make up, or by the images created by magazines and cosmetics advertisements. Cosmetics-related ads aim to express the brand image in a symbolic and compressed manner, and they function as a communication tool between the company and the consumers. As these advertisements lay out the latest trends, many depend heavily on this particular medium to understand the current style. These media also have a significant impact on how women put on make-up. Thus this dissertation is written in the hope to predict the advertisement trends to follow in the future, while also understanding the trend of base make-up by analyzing the textures of base make-up from a total of 32 advertisements of season make-up from 2006 to 2013, an image collected from 32 ads from the following brand homepages: the two brands with the largest market domination Amore Pacific’s Hera, which uses female models in their 20-30’s, and LG Household and Healthcare Brand, ; Lee Kyung Min’s Vidi Vici, a personal artist brand that has significant influence on the base make-up texture trend; . These images are chosen after in-depth consultations with experts who are qualified with at least a Masters degree in Aesthetics. As a result, it was shown in that the advertisements of Hera and O Hui, the two largest make-up brands in South Korea, well reflected the latest trends of base make-up in their ads, and also helped in understanding the trend of base make-up texture the most. The analysis also revealed that personal make-up artist brands Luna and Vidi Vici do not reflect the current base make-up texture trend in their advertisements, but rather goes beyond the current trend and reflect in their ads what will be the upcoming ones in the future.

‘맞춤형화장품 제도’가 2020년 3월 14일자로 첫 시행되었다. 맞춤형화장품 제도는 화장품 혼합 및 소분 등 다양한 소비자의 기호 반영과 맞춤형화장품 조제 관리사와 같은 전문 일자리 창출효과와 화장품 산업 활성화를 기대할 수 있다. 급변하는 경제성장의 21세기 현대사회는 단순하게 최신 유행 추구보다는 본인의 만족감을 충족시키는 소비트렌드 중심으로 개인별 취향과 특별함을 강조하는 퍼스널 형태의 맞춤형 제품 관심이 점차 확대되어지고 있다. 본 논문에서는 맞춤형화장품에 대하여 맞춤형화장품과 맞춤형화장품조제관리사, 맞춤형화장품의 시장현황에 대하여 알아보고 맞춤형화장품을 적용한 분야의 연구들을 살펴보았다. 아름다움에 대한 관심이 증가함에 따라 현대인들의 삶의 질과 생활수준 향상은 외모관리가 자기표현의 수단으로 외모는 자기 인식과 함께 인간관계에서도 중요한 요소일 것이다(김민정, 2018). 외모에 대한 관심도가 갈수록 높아지면서 소비자들은 전문가에게 지속적인 관리를 받는 것이 일상이 되어가고 있다(김지윤, 전미정, 2020). 소비자들은 자신의 외모관리를 위한 수단으로 화장품을 구매하고 사용하는데 있어서 유행을 따르기보다는 자신에게 맞는 화장품을 선호하며 맞춤형화장품에 대한 인식은 소비자의 피부상태에 맞추어 즉석에서 만드는 화장품으로 인식하고 있다. 본 연구가 미용분야에서 맞춤형화장품이 피부미용관리 프로그램에 다양하게 활용되며 기초를 다지는 데 기여할 수 있기를 기대한다. Customized Cosmetics Systems’ came into effect on 14 March 2020. With the customized cosmetics system, it is possible to reflect consumers’ various preferences to the mixture and subdivision of cosmetic ingredients, to create jobs like customized cosmetics technical managers, and to promote the cosmetics industry. In today’s society with rapid economic growth, more consumers have been interested in customized products reflecting individuals’ tastes and speciality in the consumption trend for self-satisfaction, rather than the pursuit of the latest fashion. This study tried to find customized cosmetics, customized cosmetics technical managers, and the market state of customized cosmetics, and to look into other studies on customized cosmetics. As people pay more attention to beauty along with the improved quality of life and standard of living, their care for looks is the means of self-expression. Therefore, appearance together with self-awareness is a critical factor in human relationship (Kim Min-jeong, 2018). The more consumers are interested in their looks, the more they receive professional care in everyday life (Jeong Mi-jeong, 2020). When buying and using cosmetic products as the means for appearance management, consumers prefer the cosmetics suitable for themselves, rather than follow a fashion and think of customized cosmetics as the cosmetic products made instantly in consideration of their skin conditions. It is expected that this study contributes to applying customized cosmetics much to skin care programs and laying the foundation for them.

Mean residence time has been measured in a continuous stirred tank reactor by the analysis of age distribution function in order to determine the effect of agitator speed and liquid flow rate. The data were obtained in the ranges of agitator speed from 50 rpm to 100 rpm and liquid flow rate from 50 ml/min to 150 ml/min. Age-distribution curve was studied by measuring the conductivity of KCl as a tracer. The effect of agitator speed and liquid flow rte on the mean residence time are determined. The parameter f(t￣_exp / t￣_p) represents the degree of deviation from perfect mixing. The parameter f was found to be strongly affected by agitator speed but little affect by liquid flow rate.

뇌경색후 발생한 Cortical Spreading Depression과 뇌경색 범위에 관한 실험적 연구

박윤관,이승민,김세훈,이기찬,주정화,이훈갑 대한신경외과학회 1996 Journal of Korean neurosurgical society Vol.25 No.3

Cortical Spreading Depression(CSD) is a transient depression of neuronal activity that spreads across the cortical surface and is associated with profound changes in blood flow, extracellular ion concentration. Direct Current(DC) potentials and cell membrane potentials. One of the electrophysiological disturbance in the periinfarct surrounding is spontaneous occurrence of repeated CSD like DC shifts associated with increased energy demand. Due to restricted blood flow to the periinfarct border zone, elevated metabolic demand is potentially harzardous. So the authors designed this experiment to verify the correlation between periinfarct cortical spreading depression and ischemic volume following permanent middle cerebral artery (MCA) occlusion in rats. Sprague-Dawley rats(n=27) were anesthetized with 0.5∼1% halothane, and artificially ventilated through a tracheal cannula. Arterial pressure, blood gases and body temperature were controlled. The middle cerebral artery(MCA) was occluded distally to the lenticulostriate branches. Measurements of CSD activity were made for 4 hours in each animal. Infarct volume was determined 6 hours later in 2, 3, 5-triphenyl tetrazolium chloride(TTC)-stained sections. For 4 hours after MCA occlusion, the CSDs were found in all experimental animals with a range of 2∼9 times. Those CSDs wer of varying duration, : "small"(<1 min) and "big"(> 1 min) SDs and mean of total duration of SD was 10.5±10.3 min during 4 hours of MCA occlusion. Neuropathological evaluation of brain infarct in the rats, which had been allowed to survive for 6 hours after MCA occlusion showed a mean volume of 89.7±45.3㎣. Serial observation of duration of CSD showed progressive prolongation only in 8 rats. The rest of them(n=19) did not show any prolongation. Neither the prolongation of duration of CSD nor the frequency of CSD in the penumbral zone correlated with the volume of infarct. However total duration of CSD was slightly related with the infarct volume after 6 hours of the permanent MCA occlusion(r=0.414, p=0.0318).
