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.

Objectives: This study was performed to find the desirable remaining time of needle in the acupuncture treatment. Methods: The 21 volunteers were given acupuncture at LU9 vertically and needles were remained for 2 min, 10 min, 15 min, 30 min, respectively. The thermographic change induced by acupuncture was measured with Digital Infrared Thermographic Image at the following acupoints: LU11, LU10, LU9, LU8, LU5, LU1, and PC7. The statistical significance of thermographi change was evaluated using paired t-test and post hoc Wilcoxon test. Results: The most significant changes after acupuncture were produced when needles were remained for 10 min or 15 min. LU11, LU5, LU1, and PC7 were the point at which all of the remaining time produced significant change commonly. At LU11, the biggest change was produced when needle was remained for 15 min, while at LU5, LU1, and PC7, the biggest change was produced when needle was remained for 30 min, and the smallest change was produced when needle was remained for 10 min at all of acupoints of LU11, LU5, LU1, and PC7. The unbalance between left side and right was decreased the most largely in 15 min group. Conclusions: The results of this study suggest that the desirable remaining time of acupuncture needle might be 15 min.

The effect of hydrodynamic forces generated by air bubbles on cell growth of continuous culture of SynechocystisPCC 6803 was studied in a flat-panel photobioreactor. Keeping all relevant parameters constant enables the optimizationof individual parameters, for which a continuous cultivation approach has significant advantages. Continuous culture ofSynechocystis PCC 6803 was cultivated under different gas velocities from 0.022 m s−1 up to 0.128 m s−1. Based ondirect determination of effective growth rate at constant cell densities, cell damage due to shear stress induced by theincreasing gas velocity at the sparger was directly observed. A significant decrease of effective growth rate was observedat gas velocity of 0.085 m s−1 generated at the gas flow rate of 200 ml min−1, indicating cell damage by shear stress. Optimization of gas volume and the development of an effective aeration system corresponding to a given reactor setupis important to realize a reliable cell growth.

Hong, Sung-Tae,Lee, Sang Hyup,Lee, Seung-Jin,Kho, Weon-Gyu,Lee, Mejeong,Li, Shunyu,Chung, Byung-Suk,Seo, Min,Choi, Min-Ho 梨花女子大學校 藥學硏究所 2003 藥學硏究論文集 Vol.- No.12

Praziquantel is rapidly absorbed and secreted; and thus fractional doses are recommended for the treatment of cestode and trematode infections. In the present study, we developed a new praziquantel tablet formula allowing sustained-release (SRP). In vitro dissolution of SRP tablets showed that praziquantel at 300 ㎎/tablet combined with hydroxypropyl methylcellulose dissolved completely at a constant rate over 10 h, whereas the conventional praziquantel tablet (PZQ) was only 40% dissolved. Pharmacokinetic studies in dogs confirmed that SRP was absorbed more slowly than PZQ. The mean value of the area under the concentration/time curve from 0 h to the final observation time, the maximum concentration in serum, and the time of maximum concentration in serum for SRP were 3.471.500 ng/min for 0.25 ㎖, 10,300 ng for 0.25 ㎖, and 192 min. while the values for PZQ were 688,600 ng/min for 0.25㎖, 2,500 ng for 0.25㎖, and 135 min. The cure rate in dogs with a heavy infection (500 metacercariae) treated with a single dose of SRP (150 ㎎/tablet) at 50 ㎎/㎏ was 80%, while in dogs treated with a single dose of SRP (300 ㎎/tablet) at 30 mg/kg it was 60%, and the cure rate with PZQ was 20%. In each case. the egg reduction rate was similar (over 90%). No abnormal liver functions or hepatic or renal pathologies were observed in dogs administered with SRP at 30 ㎎/㎏. The SRP tablet showed sustained release and slow absorption; and it had an improved anthelmintic efficacy against Clonorchis sinensis in experimental dogs. compared with conventional praziquantel.

본 연구는 열수 침지, 증기 및 볶음 처리가 표고버섯에 미치는 이화학적 분석 및 영양성분 분석을 통해 최적 열처리 조건을 확립하고자 진행하였다. 소비자들이 상품을 평가할 때 1차적으로 먼저 관찰되는 색도와 경도를 측정하고 추가로 pH 측정 등으로 인한 이화학적 결과로 최적 조건을 선정한 뒤에 그 조건들에 대해서 영양학적 및 미생물 검사를 실시하였다. 색도는 열처리 시간이 길어질수록 색의 변색 정도가 증가하여 뚜렷한 차이를 나타내었다. pH 값은 열수 침지 처리의 경우 pH 증가량이 가장 높았으며 처리 시간이 지속될수록 pH가 증가하는 경향을 나타내었다. 다른 처리군의 경우 일정 시간의 처리 시간 이후에는 유의적인 차이를 보이지 않았다. 경도에서는 열수 침지와 볶음 처리의 경우 1분 이내의 열처리만으로도 경도가 감소하는 경향을 보였으며, 증기처리의 경우 1분 동안 경도가 유지되는 결과를 보였다. 일반성분 분석 결과는 증기 처리가 가장 원물에 가까운 결과를 나타냈다. 유기산 함량은 증기 처리에서 유기산 함량 감소율이 가장 낮았다. 또한 3분간 증기 처리를 하였을 때 미생물의 사멸 효과가 가장 높았다. 열수 침지 처리나 볶음 처리의 경우 전체적으로 증기 처리한 시료에 비해서 영양성분 함량이 줄어드는 경향을 나타냈다. 따라서 표고버섯을 증기 처리방법으로 열처리하는 것이 다른 열처리군에 비해서 최적으로 나타났다. 하지만 본 연구에서는 물리화학 및 영양학적 성분의 변화만을 분석하였기 때문에 실제 식품 산업이나 공정에 적용하기 위해서는 대용량 처리 시에 발생하는 문제들과 관련된 추가적인 연구를 필요로 할 것이다. In the food industry, thermal treatment is an important process for extending shelf-life of foods. However, heating process affects the physicochemical, nutritional, and microbial properties of foodstuff such as color, texture, pH, and proximate compositions. This study was conducted to select an optimal thermal treatment by observing physicochemical, nutritional, and microbial effects of shiitake mushrooms with different thermal treatment methods. Shiitake mushrooms were washed and sliced equally (5 cm×0.5 cm×0.5 cm) and then heat-treated by three methods. Samples were heated in 100°C boiling water, steamed for 10 min, or pan fried at 130°C for 4 min. Total color difference values showed significantly increasing tendency with treatment time. For pH values, boiling water-treated mushrooms showed increasing tendency according to increased thermal treatment. For the results of hardness, boiling water or pan frying-treated mushrooms showed reduced tendency within 1 min. In the case of steam-treated mushrooms, hardness values were maintained for 1 min. Organic acid contents of steam-treated sample showed the lowest value among treatments. For microbial counts, steam-treated samples for 3 min showed the lowest value. Consequently, the results of this study suggest that steam treatment could be the optimal thermal treatment to minimize quality loss of shiitake mushrooms.

Impact of Irradiation Time on the Hydrolysis of Waste Activated Sludge by the Dielectric Heating of Microwave

Tae Joo Park,Im Gyu Byun,Jae Ho Lee,Ji Sung Lim,Jeong Min Lee 대한환경공학회 2014 Environmental Engineering Research Vol.19 No.1

The effects of initial solid concentration and microwave irradiation (MWI) time on the hydrolysis of waste activated sludge (WAS)were investigated. MWI time strongly influenced WAS hydrolysis for all initial solid concentrations of 8.20, 31.51, and 52.88 g VSS/L. For all WAS, the volatile suspended solids (VSS) solubilization degree ranged from 35.6% to 38.4% during a total MWI time of 10 min. Solublechemical oxygen demand (SCOD) concentration increased at a rate proportional to the decrease of VSS during the MWI. However, the clearly different VSS solubilization patterns that were observed during the MWI were explained by the 2-step hydrolysis of WAS, consisting of the initial disintegration of the easily degradable part of the sludge, followed by the subsequent disintegration of the hardlydegradable part of the sludge. WAS hydrolysis rates for 3 to 6 min of MWI were significantly lower than those for less than 3 min, or more than 6 min. From these results, 3 min MWI time and WAS of 31.51 g VSS/L (centrifugal thickener WAS) showed the most efficienthydrolysis of WAS at 36.0%. The profiles of total nitrogen (T-N) concentrations corresponded well to the SCOD increases in terms of the empirical formula of bacterial cell mass (C5H7O₂N). The negligible T-N increase and pH decrease during WAS hydrolysis by MWI will allowthe application of this process to subsequent biological processes, such as anaerobic digestion.

成敏雄,金鼎錫,金鎭聖,鄭宇珪 慶尙大學校 1986 論文集 Vol.25 No.2

Kalanchoe속에 속하는 3種을 대상으로 잎과 꽃잎의 表皮構造와 氣孔의 發生類型을 조사한 結果는 다음과 같다. 잎의 表皮細胞는 主로 多角形이고 꽃잎의 표피세포는 主로 伸長形이었다. 이들의 細胞壁은 肥厚되었고, 直線形이거나 弓形이었다. 副細胞壁은 얇고 弓形이었다. K. tomenlosa의 잎에서 三方射星狀毛가 K. blossfediana의 꽃잎에서 角皮條紋과 옥살산컬슘의 結晶體가 발견되었다. 잎에서 氣孔의 數는 얇은 잎으로 된 일반식물에서 보다 적었고 잎의 양면에서 氣孔數의 차이도 일반식물에 비해 적었다. 성숙한 기공의 主類型은 螺旋型이었다. 기공의 發生學的 類型은 全中位形成 螺旋型이었고, 이 유형은 孔邊母細胞의 分裂角에 따라 全中位形成平行螺旋形과 全中位形成不規則螺旋形의 두 종류의 亞型으로 나눌 수 있었다. 全中位形成四副細胞型內不均等型 및 全中位形成對生型과 全中位形成不均等型의 中間型 기공의 부세포들 중앙에 全中位形成四副細胞型이 管束植物에서는 최초로 발견되었다. The epidermal structure and ontogeny of stomata in the leaves and petals Kalanchoe were described. The epidermal cells were mainly polygonal cells. These cell walls were thick and straight or arched. The subsidiary cell walls were thin and arched. The triradiate stellete hairs in the leaves of K. tomentosa, and the cuticular striation and square crystals of calcium oxalate in the petals of K. blossfeldiana were observed. The stomatal number in the leaves had relatively fewer stomata than thin-leaved common dicots with only one lower surface. The difference of stomata number on te both surfaces of leaves in each species was relatively lower than that of common plants. the main type of mature stomata was helicocytic type. the ontogenetic type of stomata was mainly helico-eumesogenous type. This type was subdivided into parahelico-eumesogenous and anomohelico-eumesogenous stomata on the base of the division angle of the guard mother cells. The coaniso-tetra-eumesogenous type and tetra-eumesogenous type in the center of the intermediate stoma between the allelo-eumesogenous and aniso-eumesogenous stomata in the leaf of K. kewensis were first observed in vascular plants.
