In this paper, reflex RGB data captured from WebCam is stored to HDD through USB port at every 5 seconds intervals. Also, if strangers are detected through Motion Detection routine, warning voice message is broadcasted and invasion message is transmitted by e-mail and transmit the e-mail title to mobile phone through WAP(Wireless Application Protocol) Push. The detected image is stored to hard-disk in 'month - day - hour - minute - second . jpg' data type. And the image data is transmitted to web server through FTP(File Transfer Protocol) because invader can deletes or destroys the image data on hard-disk. We implement a surveillance system which is able to utilize through internet regardless of time and space.

Kyung Jun Hwang,Hyung Soo Park,Nam Geon Park,Moon Suk Ko,Ha Yean Jeong,Moon Chul Kim,Sang Teak Song 한국초지조사료학회 2009 한국초지조사료학회 학술대회논문집 Vol.2009 No.08

This experiment was conducted to compare forage production and grass intakes of warm season grasses for grazing horses in Jeju. The experimental field located at 450m altitude(Jeju Horse Training Center of Korea Racing Association) was divided into 3different treatment plots(3replications) without a fence between treatments, and sown by three treatments(bermudagrass, bahiagrass, bermudagrass+bahiagrass mixture). Three castrated adult horse a were kept on pasture from the 1 of October to the end of October without supplementary concentrates. 'Bahiagrass' cultivar showed the highest dry matter (DM) yield with 8,887㎏/㏊ than those in other treatments (bermudagrass 8,699, bermudagrass+bahiagrass mixture 8,385㎏/㏊). The percentage of grass intakes was higher in the treatment of bahiagrass(92%) than those in other treatments(bermudagrass+bahiagrass mixture 89, bermudagrass78%). The results indicate that the warm season grasses of bermudagrass, bahiagrass, bermudagrass+bahiagrass mixture can be used for grazing pasture of horses in the Jeju.

Optimization for an Isoflux Pattern From a Multiring Microstrip Array via Least-Squares Regression

Jeong, Seong-Yeop,Lee, Teak-Kyung,Lee, Jae-Wook IEEE 2017 IEEE antennas and wireless propagation letters Vol.16 No.-

<P>This letter presents a novel optimization via the theoretical modeling of an array geometry for isoflux patterns from a satellite antenna. The array has a multiring geometry capable of realizing the source distribution and ring radii similar to a sinc function shape. Additionally, the array uses the sequential changing of the phase excitations in order to favor circular polarization. By means of the cavity model, a synthesized electric field from the array antenna is formulated. For the desired isoflux pattern, the formulated electric field is analytically optimized via the least-squares regression iteration process. The results of the optimization show the approximately uniform electric-field illumination on the ground from a satellite antenna.</P>

본 시험은 2003년부터 2005년까지 방목 혼파초지에 우분퇴비 시용에 따른 사초의 무기성분 함량변화를 구명하기 위하여 난지농업연구소 조사료포장에서 수행되었다. T1) 화학비료 100%, T2) 화학비료 50% + 퇴비 50%, T3) 화학비료 25% + 퇴비 75%, T4) 퇴비 100%, T5) 퇴비 100%(1년차) + 화학비료 100%(2년차) + 퇴비 100% (3년차), T6) 퇴비 100% (1년차) + 화학비료 100% (2년차) + 화학비료 100% (3년차)로 처리를 두어 우분퇴비 시용이 혼파초지의 다량무기성분 함량변화에 미치는 영향을 조사하였다. 연간 총 건물수량을 비교해보면 시험1년차에는 T1 처리구가 11,342 ㎏/ha, 시험2년차에는 T5 처리구가 13,468 ㎏/ha, 3년차는 T6 처리구가 10,724 ㎏/ha로 가장 높은 수량을 보였으며 시험기간 동안 평균 건물수량은 화학비료구가 11,486 ㎏/ha으로 가장 높은 건물생산성을 보였지만 처리 간 유의성은 없었다. 식물체의 다량무기물 함량은 목초의 K 함량에서 T4 (우분퇴비 100%구) 처리구에서 높았으며 (p<0.05), 년차가 진행될수록 함량이 다소 증가되는 경향을 보였다. 식물체의 Ca 함량도 T3 (화학비료 25% + 우분퇴비 75%구) 처리구에서 3년 모두 일정하게 다른 처리보다 높았으며 통계적으로 유의차가 인정되었다 (p<0.05). 목초의 Ca 및 Mg 함량은 모든 처리 일정하게 조사기간 3년 동안 2003년에 가장 높았고 2005년, 2004년 순으로 함량이 감소되었다. 목초의 Na 함량은 모든 처리 일정하게 Ca과 Mg 함량과 반대되는 경향을 보이고 있었다. 결론적으로 우분퇴비의 시용은 목초내 다량무기성분에 있어서 결핍이나 과다함유되지 않았으며, 가축이 섭취하는 데 있어 안전하다고 사료된다. This experiment was conducted to investigate the effect of cattle manure application on macro contents change in pasture. The treatment consisted of T1: 100% chemical fertilizer (CF 100%), T2: 50% CF + 50% cattle manure (CM), T3: 25% CF+75% CM, T4: 100% CM 100%, T5: 100% CM(1st year (yr.) + 100% CF (2nd yr.) + 100% CM (3rd yr.), T6: 100% CM (1st yr.) + 100% CF (2nd yr.) + 100% CF (3rd yr.). The highest substitution effect of chemical fertilizer with cattle manure indicated by the highest yield of 11,169 ㎏/ha was obtained from the application of 100% CM (1 yr.) + 100% CF (2 yr.). The forage yield of plots applied with 100% CM (1 yr.) + 100% CF(2 yr.) was only 4% more than the yield of plots applied with 100% CM. It was only 3% less than the yield of plots applied with 100% CF. In this study, cattle manure application recorded slightly lower forage dry matter (DM) yield than 100% CF application but they were statistically comparable on the third year of production. The all treatments have narrow range of P, K, Ca, Mg and Na contents 0.25~0.32%, 3.08~3.71%, 0.42~0.55%, 0.21~0.38% and 0.08~0.15%.

Nan Kyung Kim,Hae Lim Jeong,Ye Jin Kim,Weon Teak Seo,Ji Hyun Kim 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

In this study, we investigated the physicochemical characteristics and in vitro antioxidant activities of yogurt added with Artemisia argyi. The A. argyi yogurt was prepared with powdered skim milk, oligosaccharide, and A. argyi at doses of 0, 0.5, 1, 2%, and then fermented with commercial starter for 18 h at intervals of 6 h. During fermentation, pH of yogurt added with A. argyi was decreased to 4.43 to 4.46. However, the acidity and the number of viable cells of yogurt added with A. argyi were increased during fermentation period. The yogurt added with 1% A. argyi at 18 h fermentation had highest lactic acid at 9.08 mg/g compared with other yogurt. In addition, total polyphenols and flavonoids contents of yogurt added with A. argyi significantly increased in a dose dependent manner. Furthermore, the 1,1-diphenyl-2-picrylhydrazyl and 2,2’-azubibus-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activities of yogurt dose-dependently increased as the amount of A. argyi increased. Therefore, these results suggest that the addition of A. argyi in yogurt is considered to be suitable for functional fermented milk products by antioxidant activity.

Anti-Atherosclerotic Effect of a New Synthetic Functional Oil Containing Mono- and Diacylglycerol from Corn Oil

Cho, Kyung-Hyun,Han, Jong-Min,Jeong, Tae-Sook,Kim, Hyoung-Chin,Lee, Jong-Ho,Lee, Jeung-Hee,Lee, Ki-Teak S. Karger AG 2006 Annals of nutrition & metabolism Vol.50 No.5

<P>Synthetic oil containing diacylglycerol and monoacylglycerol, called ‘functional oil’ (FO), was newly produced and evaluated for its putative anti-atherosclerotic potential by in vitro assays and in vivo test using hypercholesterolemic mice (C57BL/6). The FO revealed good inhibitory activities against both liver acyl-CoA:cholesterol acyltransferase and serum lipoprotein-associated phospholipase A<SUB>2</SUB>. The FO showed enhanced activities on lipoprotein interaction such as HDL particle rearrangement to produce different sizes of HDL species. In control mice, hypercholesterolemia was induced by consumption of high-cholesterol, high-fat (HCHF) diet that contained 1.25% cholesterol/15% fat/0.5% Na-cholate with or without 5% of corn oil. In experimental mice, 5% of the FO + HCHF diet was fed during the same period. After the 4-week administration of the diet, serum total cholesterol concentration of the FO-fed group decreased by 38 or 20% when compared to the HCHF diet control group or corn oil (99.9% of triacylglycerol) diet group, respectively. The percentage of HDL cholesterol to total cholesterol was 36% of HDL cholesterol in the FO-fed group, while the HCHF control group and corn oil-fed group showed 21 and 25%, respectively. These results indicate that the FO possesses a blood cholesterol-lowering effect in mouse model and inhibition effects against the atherogenic enzymes.</P><P>Copyright © 2006 S. Karger AG, Basel</P>

정철영(Jeong, Chul-Young),이경택(Lee, Kyung-Teak),송순호(Song, Soon-Ho),전광민(Chun, Kwang-Min),남상익(Nam, Sang-Ick) 한국신재생에너지학회 2009 한국신재생에너지학회 학술대회논문집 Vol.2009 No.06

Research on usage of syngas produced by waste gasification is on going all around the world. Syngas which consists of H₂, CO, CO₂, N₂, has different combustion characteristics from current city gas; due to distinct flame propagation speed of the fuel, syngas has different spark timing and air fuel ratio at maximum generating efficiency. This is why finding both the optimum point of spark timing and air fuel ratio is so important in order to improve thermo efficiency and secure stable running of gas generated by relatively low heating value syngas. Moreover, since emission of NO_x is strictly regulated, it is important to operate lean burn condition that reduces NOx emission.

Genetic Distinctness of Sorex caecutiens hallamontanus (Soricomorpha: Mammalia) from Jeju Island in Korea: Cytochrome Oxidase I and Cytochrome b Sequence Analyses

Koh, Hung-Sun,Jang, Kyung-Hee,In, Seong-Teak,Han, Eui-Dong,Jo, Jae-Eun,Ham, Eui-Jeong,Jeong, Seon-Ki,Lee, Jong-Hyek,Kim, Kwang-Seon,Kweon, Gu-Hee The Korean Society of Systematic Zoology 2012 Animal Systematics, Evolution and Diversity Vol.28 No.3

To examine genetic divergences of two endemic Sorex caecutiens subspecies from Korea (S. c. hallamontanus in Korean Jeju Island and S. c. annexus in the mainland Korean Peninsula), we obtained partial cytochrome oxidase I (COI) sequences (429 bp) and complete cytochrome b sequences (1,140 bp) from the two Korean subspecies, and we compared these sequences to the corresponding sequences of S. caecutiens, obtained from GenBank. We found that Jeju S. c. hallamontanus is one of three clades within S. caecutiens, with an average Jukes-Cantor distance of 1.57% in the COI sequences and the distance of 2.07% and 11 fixed site differences in the cytochrome b sequences, indicating that Jeju S. c. hallamontanus is one endemic subspecies with concordant genetic distinctness, although further analyses with nuclear DNA sequences are necessary to confirm these findings. However, S. c. annexus from the mainland Korean Peninsula was not divergent from S. c. macropygmaeus from northeastern China and adjacent Russia, indicating that S. c. annexus from the mainland Korean Peninsula is another endemic subspecies with only morphological differences, although it is necessary to reexamine the subspecies status of S. c. annexus.
