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,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,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.

Objectives: The purpose of this study was to determine the difference in the genotype distribution of Porphyromonas gingivalis (P. gingivalis ), the main cause of periodontal disease, according to smoking status. Methods: Two hundred thirty adults with periodontal disease were selected as subjects and were classified into either a smoking or non-smoking group. Smoking behavior was assessed with a self-administered questionnaire, and subgingival plaque was collected and analyzed using polymerase chain reaction to confirm the P. gingivalis genotype. For statistical analysis, SPSS Ver 25.0 was used. Results: P. gingivalis was expressed in 224 subjects (97.4%), and there was no difference in its expression rate according to smoking. However, there was a significant difference in smoking in type III genotype and smoking period in type II genotype with P. gingivalis (P =0.003). Conclusions: Although smoking was not related to the overall distribution of P. gingivalis , increased volume and duration may inhibit the expression of type II and type III genotypes.

고조선의 도읍지, 건국(建國) 년도, 국호 등에 관한 고찰

김진경 ( Jin Kyoung Kim ) 국제뇌교육종합대학원 국학연구원 2014 선도문화 Vol.16 No.-

그간 고대 역사적 지명들의 위치가 잘못 추정되었다. 왜냐하면 중국 25사 지리지에 지명의 위치를 북쪽 또는 동북쪽 방향으로 변이시키는 위사들이 삽입되어 있기 때문이다. 그러나 위사(僞史)와 진사(眞史)를 분별하여 위사를 걷어내고 나니, 고대 역사적 지명들의 위치를 올바르게 추정할 수 있었다. 또 고대 지명의 위치를 올바르게 추정하고 나니, 『삼국사기』와 『삼국유사』의 기록에 따라 환웅의 태백산 신시, 단군이 건국한 고조선의 도읍지 평양성과 아사달의 위치를 현재의 산서성 대동(大同)시에 위치한 태백산 주변 일대, 현재의 산동성 덕주(德州)시 동쪽 지역, 현재의 하북성 내구(內邱)현과 산구(山口)현 등으로 각각 추정할 수 있었다. 또 고조선의 건국년도가 서기전 2333년 보다 213년이 앞선 서기전 2546년으로 추론할 수 있었으며, ‘고조선(왕검조선)’이라는 국호가 원래 ‘조선(朝鮮)’이 아니고 ‘숙신(肅愼)’ 또는 ‘단국(檀國)’으로 추정해 볼 수 있는 근거를 찾을 수 있게 되었다. For the time, the location of historical geographical names were incorrectly designated, because the fault historical facts were inserted in the Chinese historical books to distort the location of geographical names to the direction of north and east-north. But if the fault historical facts were scummed, we can seek the correct location of ancient historical geographical names. And on the base of the correct location of geographical names, can we reason the location of the Sin-si of the Mt. Tae-back of Hwan-Ung, the Castle Pyong-Yang and the A-Sa-Dal which were the Capital of tne Gojoseon of Dan-Gun according to the records of the Sam-Guk-Sa-Gi and the Sam-Guk-U-Sa. They could be assumed the area surrounding the Mt. Tae-back at the present Datong(大同) city of the Shanxi(山西) province, the eastern area of the present Dezhou(德州) city of the Shandong(山東) province, and the area of Nai-Qiu(內丘) hyeon and Shankou(山口) hyang of the Hebei(河北) province respectively. Besides can we pressum that the year of foundation of the Gojoseon was the B.C. 2546, 213 year earlier than B.C. 2333, and the name of Gojoseon(Wang-Gum-Jo-Seon) was not originally Joseon but was assumed a ‘Suk-sin(肅愼)’ or a ‘Dan-Guk(檀國)’.

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.
