시판 마요네즈를 이용하여 오이 흰가루병에 대한 방제효과를 시험하였다. 마요네즈를 0.5~2% 농도로 물에 희석하여 흰가루병이 발병된 오이에 6일 간격 3회 처리했을 때 8.3~99.2% 방제효과를 나타내었다. 90% 이상의 방제효과를 보인 마요네즈 희석액 중 2-3엽의 어린모에서 약해가 없었던 농도는 0.5%이었다. 마요네즈 중 기름함량이 78~80% 수준인 일반 마요네즈와 기름함량을 38~70%로 줄인 저지방 마요네즈의 흰가루병 방제력을 비교했을때 저지방 마요네즈는 방제율은 39.3~59.8% 수준으로 일반마요네즈에 비해 방제율이 떨어졌다. 마요네즈가 처리된 잎의 엽록소 함량은 발병구에 비해 엽록소 함량이 약 3배 정도 높게 조사되어 처리된 마요네즈가 오이 잎의 광합성을 저해하지 않으면서 흰가루병을 효과적으로 방제함을 확인하였다. This study was conducted to develop an organic control of powdery mildews of cucumber by using mayonnaise in green house. The treatment of 0.1~2% mayonnaise resulted in 8.3%~99.2% control efficiencies against powdery mildew of cucumber. 0.5% mayonnaise treatment resulted control values over 97% in disease. It did not adversely affected the photosynthesis of foliages. Although one application of mayonnaise to the foliage was not practically effective enough, two or three application of mayonnaise to the foliage at the 0.5% concentration resulted in excellent control against powdery mildews. This treatment could provide protection for 10~14 days after application. Among the type of mayonnaise, general mayonnaise revealed 97.5% control value, but mayonnaise containing low oil content revealed 39.3%~97.5% control values on powdery mildews at the 0.5% concentration. Therefore, oil content in mayonnaise played a essential material to control powdery mildew. Results indicated that mayonnaise could be used as organic control of powdery mildews of cucumber. This control might be environmentfriendly as well as cost-effective.

김진경,Kim, Jin-Kyoung 한국임상보건과학회 2020 한국임상보건과학회지 Vol.8 No.2

Purpose: The purpose of this study was to differences in the expression rate of Porphyromonas gingivalis according to smoking status, smoking amount and period of smoking. Methods: At the time of investigation, 30 smokers and non-smokers were recruited among patients with periodontitis with a probing pocket depth(PPD) of 4 mm or more. General information was collected using a self-questionnaire, and the average value was used by a dentist to measure the probing pocket depth of three times each for the first or second molar. Plaque collection and analysis were performed by collecting only subgingival plaque using a conventional method, and the expression rate of P. gingivalis was confirmed using polymerase chain reaction (PCR). For statistical analysis, the SPSS Ver 25.0 program was used. Results: Smoking did not have a significant effect on the expression of P. gingivalis, but it did affect the expression of more type II genotypes (p<0.05). In addition, smokers had more slight periodontal pocket, and the amount and duration of smoking did not affect the expression of P. gingivalis. Conclusions: In the future, it is necessary to reinforce the group of smokers and non-smokers with healthy oral conditions, and to investigate the quantitative difference in the expression rate and genotype of P. gingivalis over time of harmful substances in smoking.

김진경,우경식,윤석훈,석봉출,Kim, Jin-Kyoung,Woo, Kyung-Sik,Yoon, Seok-Hoon,Suk, Bong-Chool 한국해양학회 2007 바다 Vol.12 No.4

동해 한국대지의 정상부 해저산 사면에서 획득한 코어퇴적물의 퇴적상 분석, 입도와 구성성분 분석, $^{87}Sr/^{86}Sr$ 초기비를 이용한 연대측정을 통하여, 세 단계에 걸친 코어퇴적물의 퇴적과정을 해석하였다. 코어의 하부 구간인 Unit I-a (코어깊이 $465{\sim}587cm$)는 주로 폭풍파에 의해 재동된 천해성 탄산염퇴적물로 이루어져 있으며, 이매패류와 부유성 유공충의 $^{87}Sr/^{86}Sr$ 초기비를 분석한 결과, 퇴적물의 생성시기가 약 $13{\sim}15Ma$(마이오세 중기)로 나타났다. 이는 당시 이 지역 일대가 폭풍파의 영향을 받는 천해환경이었음을 의미한다. Unit I-b (코어깊이 431$\sim$465 cm)는 저탁류에 의해 운반된 퇴적물로 이루어져 있으며, 이매패류와 부유성 유공충의 생성연대는 각각 약 $11{\sim}14Ma$, 약 $6{\sim}13Ma$인 것으로 분석되었다. 이로부터 11 Ma까지는 이 지역 일대가 천해환경을 유지하고 있었으나 그 이후로는 침강하기 시작하였음을 알 수 있다. 그러나 부유성 유공충은 11 Ma 이후에도 지속적으로 생성되어 퇴적물 내에 공급되었으며, 이렇게 생성된 퇴적물들은 연안이나 사면과 같은 근해역에 퇴적되어 있다가 6 Ma 경에 저탁류에 의해 사면 아래로 재동되어 퇴적된 것으로 해석된다. Unit II (코어깊이 $0{\sim}431cm$)는 주로 원양성 퇴적물로 이루어져 있으며, 부유성 유공충의 생성연대가 약 1 Ma로 분석되어, 이로부터 Unit I-b와 Unit II 사이에 약 5 Ma 정도의 결층(hiatus)이 있는 것을 알 수 있다. 또한 Unit II가 퇴적되었던 1 Ma 경에는 이 지역 일대가 충분히 침강하여 현재와 같이 수심 600 m 이상의 심해저환경을 이루고 있었으나, 때때로 주변의 급경사의 사면으로부터 암설류나 저탁류에 의해 조립질 천해퇴적물이나 화산쇄설물 등이 재동되어 퇴적된 것으로 해석된다. A piston core (587 cm long) was recovered from the upper slope of a seamount in the Korea Plateau. Three episodes of sedimentation were identified based on sedimentary facies, grain size distribution, carbonate constituents and initial $^{87}Sr/^{86}Sr$ ratio of carbonates. The lower part of the core, Unit I-a (core depth $465{\sim}587cm$) is composed of shallow marine carbonate sediments the deposited by storm surges, and is about $13{\sim}15Ma$ (Middle Miocene) based on $^{87}Sr/^{86}Sr$ initial ratio. This suggests that the depositional environment was relatively shallow enough to be influenced by storm activities. Unit I-b (core depth $431{\sim}465cm$) is mostly composed of turbidites, and Sr isotope ages of bivalves and planktonic formaminifera are about $11{\sim}14\;and\;6{\sim}13Ma$, respectively. This indicates that the Korea Plateau maintained shallow water condition until 11 Ma, and began to subside since then. However, planktonic foraminifera were deposited after 11 Ma and redeposited as turbidites as a mixture of planktonic foraminifera and older shallow marine carbonates about 6 Ma ago. Unit II (core depth $0{\sim}431cm$) is composed of pelagic sediments, and the Sr isotope age is younger than 1 Ma, thus the time gap is about 5 Ma at the unconformity. About 1 Ma ago, the Korea Plateau subsided down to a water depth of about 600 m. The sampling locality was intermittently influenced by debris flows and/or turbidity currents along the slope, resulting the deposition of re-transported coarse shallow marine and volcaniclastic sediments.

김진경,Jin-Kyoung Kim 한국임상보건과학회 2023 한국임상보건과학회지 Vol.11 No.1

Purpose The The purpose of this study was to clinically evaluate the efficacy and safety of a self-whitening patch containing a primer containing taurine and 3.0% hydrogen peroxide. Methods A double-blind randomized clinical trial was conducted on 55 subjects. The whitening patches containing 3.0% hydrogen peroxide were applied to the labial surfaces of maxillary six anterior teeth once daily for 30 minutes using a primer, and whitening efficacy was measured by △E^* values before application and at 3, 5, 7, and 10 days after application. Stability was determined using the Gingival index (GI) and visual analogue scale (VAS). Results Changes in △E^* values were clinically recognizable as early as day 5 after patch application, and whitening effects were visible by day 7. There was no statistically significant difference in gingival index (p=0.069). Conclusions Self-whitening patches using primer and 3.0% hydrogen peroxide applied once daily for 30 minutes showed effective whitening effect from the 5th day after application and could be used safely without significant side effects.

겸재진경산수화(謙齋眞景山水畵)에 나타나는 절파성(浙派性)에 관한 고찰

김진경 ( Jin Kyoung Kim ) 한국동양예술학회 2013 동양예술 Vol.23 No.-

본 논고는 회화적 관점에서 謙齋 鄭鮮(1676-1759)의 眞景山水畵에 나타나는 ‘浙派性’을 중심으로 연구하고자 한다. 먼저 浙派系北宗畵에 대한 구분의 근거는 明代童其昌(1555-1636)의 남·북종론을 배경으로 하였다. 이에 앞서 겸재의 화법에 나타나는 절파성을 단순히 동기창이 구분한 남·북종의 양식을 분리하여 정의 내리고자 함이 아님을 밝힌다. 다만 그 동안 겸재의 진경산수화는 너무 국수주의적인 시각으로 해석되거나 반대로 너무 사대주의적인 중국의 영향아래 겸재의 진경산수를 규정한 경향이 강하였다. 그런데 아이러니 하게도 겸재의 진경산수화는 창작자의 의도가 드러나는 그림임에도 불구하고 가장 기본적인 ‘繪畵’라는 관점에서 집중적으로 다양하게 조명되지 못하였다. 그런 까닭으로 겸재가 창안한 화법에서 두드러지는 浙派性을 회화적으로 고찰하여 겸재의 진경산수화가 앞으로 더욱 새롭게 해석될 수 있도록 일종의 가교역할을 하고자 한다. 주지하다시피, 절파의 특징은 회화적 요소가 강하게 나타나는 빠른 속필, 강한 명암의 대비, 자유로운 구도(변각구도), 화려한 채색의 표현들로 볼 수 있다. 그런데 겸재가 창안한 화법에 나타나는 浙派系북종화의 특징은 첫째, 속필의 亂柴준둘째, 거친 필선의 大斧劈준셋째, 자유로운 화면구성에 의한 왜곡된 구도, 넷째, 화려한 색채와 청록산수 등으로 나타난다. 이것은 분명 절파의 영향을 겸재식화 한 화법들로 볼 수 있다. 여기서는 화가의 표현이 직접적으로 드러나는 속필로써 겸재의 대표준인 난시준과 대부벽준을 중심으로 고찰하였다. This papers is contemplated China Northern School Painting style reflected Kyeom-jae jin kyoung landscape painting. Actually julpa painting style which originates Myung Period Daejin who was kind of master artisan. That``s why julpa painting style is very technical and artificial. Julpa painting style was inspiring middle of Chosun artists. Anyhow Kyeom-jae also applied that kinds of style to his work of art. Here are some common point there are such as follows; speedy sketching drawing, contrast light & darkness, freely composition, strong ink & colors. These phenomenons are having pictorial art. Matter fact, style is one of the most elusive terms in art history. Formalism has excluded the painter’s active role in the choice of style from discussion of the nature of a painting. The inherent visual features of a painting are, in fact, inseparable from the painter’s self and identity. This last point is more meaningful to this papers. I think the painter’s self and identity is showed up by art of drawing. However China Northern School style of Kyeom-jae`` the art of drawing is very important for the recognized and analysis about intention of Kyeom-jae as artist. I focused on how julpa painting style became Kyeom-jae``s the art of drawing. However I discovered the Jin kyoung landscape painting``s already used that China Northern School Painting style from he began to make work of art which is buljongdo『辛卯年楓嶽圖帖』 to late one inwangjasaekdo<仁王霽色圖>. Specially he``s nansijun(亂柴준) & bubuckjun(斧劈준) are very useful one which was becoming Kyeom-jae style by julpa painting style.

DSCs are based on a dye-adsorbed porous TiO2 layer as a photo electrode [1]. Under the illumination, dye molecules are excited and electrons are produced. The injected electrons in the conduction band of TiO2 may recombine with the electrolyte. To obtain high performance DSCs, it is essential to retard the recombination. The charge recombination can be reduced by forming core-shell structure. In this work, we investigated the core-shell structure with Al2O3 and MgO coating layer on the porous TiO2 layer. We confirmed the photovoltaic properties by I-V characteristics. The current and the efficiency was improved. In addition to, Through decrease in the width of EIS arc, which is the sum of the interfacial charge transfer resistances of both electrodes, we can be indicated that the block effect.
