This article is about the cartohistorical value and significance of the 『Joseon-jido. 朝鮮地圖, Map of Korea』, the copy of the 『Dongguk-daejeondo, 東國大全圖 Great map of Korea.』 by Jeong Sang-Gi(鄭尙驥), which is the collection of the National Museum of Korea. The conclusions are as follows. First, by the contents of the map, it is presumed that the map was made between the years 1757-1767. Therefore, it is easy to assume that the map was made in 1740s. Among the others, the map was made in the earliest days. Second, the 『Joseon-jido』 was drawn on the fine silk with the delicate lines, and the map has rvtanchuria of China and Japan, which were presumed to be included in the original map. Also, comparing the copies of 『Paldo-bundo, 八道分圖 Maps of Eight Provinces』 by Jeong to the map by trigonometry calculation, we can presume that both of the map were made by the same scale. By these reasons, the 『Joseon-jido』 is presumed to be the Dongguk-daejeondo in 『YoungJo Sillok, Annals ofKing YoungJo』, which Jeong Hang-Ryung(鄭恒齡). son of Jeong Sang-Gi(鄭尙驥). brought from home and copied it to provide the map to the HongMoonKwan(弘文館, Office of Special Advisers) in 1957(33th year of King YoungJo) Third, there are over 2200 place names mentioned in the 『Joseon-jido』, and these names are also mentioned in the Dongguk-daejeondo and the Paldo-bundo. Most of the place names of the natural features were that of the mountains. and the name of the hills were mentioned in detail. Most of the place names of the civil features were that of the military facilities, such as military camps and the mountain castles. Therefore. it can be said that the map had administrative and military purpose. Fourth, the expression of the landscape followed the classic mountain range-centered understanding while at the same time stressing the six Jeongmaks(正脈, Secondary Mountain Range), the important military defence line. The traffic route was expressed in detail among the other civil features, and the mountain castles. military camps and the signal fire were also expressed in detail with the more symbolized marks. Fifth, unlike the existed articles. the map expressed the changes in the military camps, mountain castles, traffic routes, stations and the signal fires.

정대성,김승주,이진헌,최재학,이주,Jung, Dae-Sung,Kim, Seung-Ju,Lee, Jin-Hun,Choi, Jae-Hak,Lee, Ju 한국조명전기설비학회 2007 조명·전기설비학회논문지 Vol.21 No.3

가전분야에서의 전동기 효율향상을 통한 에너지 소비절감 효과는 상당히 크지만 이를 위한 전동기의 설계/해석 기술 확보가 아직은 미흡한 상태이다. 이에 따라 유도형 동기전동기가 제안되었지만, 유도형 동기 전동기는 유도전동기와 통기전동기의 특성을 동시에 가지고 있어, 해석 및 설계가 쉽지 않다. 따라서 본 논문에서는 기존의 냉장고 압축기용 전동기인 단상유도전동기를 대처할 수 있는 단상 유도형 동기전동기를 이용해 파라미터에 따라 특성이 어떻게 바뀌는가에 대해 서술하였다. 그에 따라 단상유도전동기의 정상상태 특성을 해석하고 제안모델의 성능을 기존모델과 비교하고 실험하여 해석결과의 신뢰성을 검증한다. 또한 본 논문에서는 제안모델의 기존 고정자 형상이나 권선 스팩을 유지하고 회전자의 형상이나 구조만을 변경시켜 성능향상을 도모하였다. 해석방법으로는 전자장 수치 해석적인 방법으로 널리 이용되고 있는 유한요소법(Finite Element Method : FEM)을 이용하였다. Electric motor efficient improvement from home appliance field is important to the effect reducing the energy consumption. But the electric motor design/analysis technology is still insufficient. Specially the electric motor design/analysis technology of satisfying characteristic of both the induction motor and the synchronous motor such as Line start permanent motor. Therefore the electric motor design/analysis technology is urgently demanded reliability. This paper proposes the sing1e-phase line-start permanent magnet motor to develop the motor it with be able to alternate the sing-phase induction motor it is a refrigerator compressor motor. The sing-phase induction motor is analyzed in the steady state. And we have a certification test to compare our single-phase line-start permanent magnet motor with the sing-phase induction motor. In order to improve the performance, the stator of the single-phase line-start permanent magnet motor is same as the stator of the sing-phase induction motor and changes the rotor form and has the permanent magnet. It used the Finite Element Method(FEM) which is widely used with electronic-magnetic field numerical analysis method.

PER2 is downregulated by the LPS-induced inflammatory response in synoviocytes in rheumatoid arthritis and is implicated in disease susceptibility

Lee, Hwayoung,Nah, Seong-Su,Chang, Sung-Hae,Kim, Hyung-Ki,Kwon, Jun-Tack,Lee, Sanghyun,Cho, Ik-Hyun,Lee, Sang Won,Kim, Young Ock,Hong, Seung-Jae,Kim, Hak-Jae SPANDIDOS PUBLICATIONS 2017 MOLECULAR MEDICINE REPORTS Vol. No.

<P>The clinical symptoms of rheumatoid arthritis (RA) present with circadian variation, with joint stiffness and pain more prominent in the early morning. The mammalian clock genes, which include circadian locomotor output cycles kaput, brain and muscle Arnt-like protein 1, period and cryptochrome, regulate circadian rhythms. In order to identify the association between genetic polymorphisms in the circadian clock gene period 2 (PER2) and RA, the present study genotyped three PER2 single nucleotide polymorphisms (SNPs), rs934945, rs6754875, and rs2304674, using genetic information from 256 RA patients and 499 control subjects. Primary cultured rheumatoid synovial cells were stimulated with 10 mu M lipopolysaccharide (LPS). Total protein was then extracted from the synovial cells following 12 and 24 h, and PER2 protein expression was assayed by immunoblotting. The rs2304674 SNP demonstrated a significant association with susceptibility to RA following Bonferroni correction. However, statistical analysis indicated that the SNPs were not associated with any clinical features of patients with RA. Immunoblotting analysis demonstrated that PER2 protein expression was decreased by LPS-induced inflammation in RA synovial cells; however, this was not observed in normal synovial cells. The results suggest that the PER2 gene may be a risk factor for RA, and expression of the PER2 protein may be affected by inflammation. Therefore, PER2 may contribute to the pathogenesis of RA.</P>

Sang-Jo Park,Jun-Hong Park,Byung-Sung Kim,Yun-Hak Chung,Dong-Jun Lee,Oh-Heun Kwon,So-Deuk Park,Suk-Hee Lee 한국토양비료학회 2016 한국토양비료학회지 Vol.49 No.4

The perennial edible wild plants such as Aster glehnii, Solidago virgaurea subsp. gigantean, Allium ochotense, Athyrium acutipinnulum, Aruncus dioicus var. kamtschaticus and Codonopsis lanceolata have cultivated as the main income crops introduced into the fields about 30 years ago in Ulleung island. Soil samples were collected from 190 fields and assessed the effects of management practices on soil chemical properties at wild edible plant fields under no-till system. The strong acidic soils of pH 5.4 or less were detected in 45% of the soil samples. The level of soil organic matter was being held at mean 63±28 g kg<SUP>-1</SUP>, 2.7 times higher than upland soils in Korea. Available phosphate and exchangeable potassium showed more than recommended levels of upland crops as 680±489 mg kg<SUP>-1</SUP> and 1.94±1.7 cmolc kg<SUP>-1</SUP>, respectively. The fields of Solidago and Aster showing strong soil acidity and high level of available phosphate and water soluble NO₃<SUP>-</SUP> were distinguished from other crops in analysis of variance and principal component analysis of soil chemicals. These results suggested that high frequency of acidic soil and high levels of available P₂O5, exchangeable K₂O and water soluble NO₃<SUP>-</SUP> were accompanied with the use of urea and NPK-fertilizer based on nitrogen in the field. However, further research is needed to understand the appropriate management of fertilization and the prevention of soil acidification for wild edible plants.

A Highly Sensitive Determination of Bulk Cu and Ni in Heavily Boron-doped Silicon Wafers

Sung-wook Lee,Sang-hak Lee,Young-hoon Kim,Ja-young Kim,Don-ha Hwang,Bo-young Lee 대한화학회 2011 Bulletin of the Korean Chemical Society Vol.32 No.7

The new metrology, Advanced Poly-silicon Ultra-Trace Profiling (APUTP), was developed for measuring bulk Cu and Ni in heavily boron-doped silicon wafers. A Ni recovery yield of 98.8% and a Cu recovery yield of 96.0% were achieved by optimizing the vapor phase etching and the wafer surface scanning conditions,following capture of Cu and Ni by the poly-silicon layer. A lower limit of detection (LOD) than previous techniques could be achieved using the mixture vapor etching method. This method can be used to indicate the amount of Cu and Ni resulting from bulk contamination in heavily boron-doped silicon wafers during wafer manufacturing. It was found that a higher degree of bulk Ni contamination arose during alkaline etching of heavily boron-doped silicon wafers compared with lightly boron-doped silicon wafers. In addition, it was proven that bulk Cu contamination was easily introduced in the heavily boron-doped silicon wafer by polishing the wafer with a slurry containing Cu in the presence of amine additives.

In Korea, recently, severe cases of PCD seem to be increasing which might reflect the frequent use of various cosmetic products and procedures. Objectives: To evaluate the clinical characteristics of PCD patients and identify common allergens in those patients in Korea. Methods: 26 PCD patients who undergone patch tests were included in the study. The patch test series included the Korean standard, cosmetic series, or ‘as is’ for suspected cosmetics. Medical charts and photographs of patients were retrospectively reviewed and patch test results were analyzed. Results: 24 patients were female and 2 patients were male. The mean age was 47.9 years. 21 (80.8%) patients had a positive reaction to at least 1 allergen. 12 patients reacted to nickel and 5 patients reacted to 4-phenylendiamine DHC. 2 patients had positive patch test results to ‘as is’. Of those with positive patch test results, 14 patients (53.8%) have clinical relevance. 6 patients showed both positive allergic reaction and irritant reaction. Histopathology showed massive pigmentary incontinence with a variable degree of inflammation showing lichenoid dermatitis. Conclusion: PCD, non-eczematous form of contact dermatitis, can be caused by irritation or allergen or both. Patch test can be beneficial for the prevention and treatment of PCD especially in darker skin.
