Background: Circulating inflammatory cytokines and markers are increased in patients with psoriasis. Recent studies have shown that a higher red blood cell distribution width (RDW) is associated with disease activity in various disorders. Objectives: Our objective was to investigate whether RDW is increased in psoriasis patients, and to evaluate its association with disease severity. Methods: We conducted a retrospective study of psoriasis patients seen in single hospital in Korea. Demographic data, hematologic parameters and disease severity were collected. Results: A total of 261 psoriasis patients and 102 healthy controls were included in our study. The RDW value was significantly increased in psoriasis patients compared to healthy control (p=0.037). Compared to mild psoriasispatients (PASI<7), moderate to severe patients (PASI≥7) showed significantly higher RDW values (p=0.044). RDW did not show significant correlation with PASI (p=0.358). When patients were divided into two groups according to their RDW value (<14.6% and ≥14.6%), the mean value of PASI was not significantly different (p=0.219). Conclusion: Patients with psoriasis showed increased RDW values compared to healthy controls. It was also higher in moderate and severe disease group than mild group. RDW values were increased in psoriasis patients and it is possible that RDW value reflects the inflammatory status of psoriasis, but this needs to be evaluated in near future.

This essay purposes to explain the consciousness on time in Lee Sang’s poems, focusing specifically on his poem, Strange Reversible Reaction. The argument will start from the obvious fact that the poet"s literature was based on the discovery of the material condition, called, the colony Gyeongsung. Through this discussion, what caused rejection and distrust for the time, which appear repeatedly in his literary texts, will be explained. Once, the modernist Lee Sang was dreaming of the perfect world of modernity. But the modern world he experienced was nothing but a cruel civilization with no vitality. As a result, he gave the death sentence to the world and tried to build up a new civilization. His literary texts will answer to the question, “Did the straight line kill the circle?”

해외사례 벤치마킹에 기반한 국내 CM 대가체계 개선 시사점 도출

국내 CM은 2001년 건설산업기본법에 의해 개념과 범위가 정의된 후 지속적인 성장을 계속해 오고 있다. 하지만, 이러한 CM 제도에 기반한 성장에도 불구하고 국내에서의 CM 적용성과는 기대치에 비해 상대적으로 낮은 것으로 나타났다. 그 주요원인의 하나로 국내 CM제도가 책임감리에 비하여 업무범위가 넓지만, 대가기준은 책임감리에 비해 낮기 때문인 것으로 분석되었다. 따라서, 국내 CM 대가체계의 합리적인 기준을 정립하는 것이 시급할 것으로 판단된다. 본 연구에서는 CM 대가체계의 합리적인 기준을 마련하기 위하여 CMAA, ASCE, DOE, DOL 등의 다양한 해외사례 벤치마킹 연구를 통하여 국내 CM 대가체계를 비교하여 대가 상승요인을 추정하고 대가산정 개선방향을 제시하였다. 분석결과 대가수준은 해외에 비하여 현저하게 낮은 수준인 것으로 판단되었으며, 업무범위는 해외와 비교하여 그 폭이 좁으며 획일적인 구조를 가진 것으로 분석되었다. 따라서, 본 연구에서는 글로벌스탠다드에 따르는 국내 CM 대가체계를 개선하기 위하여 실비정액보수가산(Cost Plus Fixed Fee) 방식을 제시하고, 입 낙찰 전반에 걸친 CM 대가체계에 대한 기준(Framework)을 제시하였다. The Korean Construction Industry significantly contributed to the Korean economic development not only by preparing the domestic infrastructure but also by successfully conducting various international projects. However, major incidents such as the collapse of Sung-Su Bridge and Sam-Pung Department Store along with stagnation of Korean Economy have raised questions about underlying systematic problems of the Korean Construction Industry. As a solution to resurrect the Korean Construction Industry, the Construction Management (CM) system introduced in late 1990's and increasingly utilized as an innovative delivery system. Despite of the fast growth of CM, the performance of CM has not been up to the hype and low CM fee has been identified as one of the main reasons of unsatisfactory CM performance. Therefore, this research attempted to propose ways of improving 'CM Fee Guidelines' published by Korean Ministry of Construction and Transportation by conducting a benchmarking study on Global Standards of estimating CM Fee. International organizations benchmarked in this research include CMAA, ASCE, DOL, DOE, etc. Various investigation and analysis revealed that Korean 'CM Fee Guidelines' need to significantly modified comparing to Global Standards. This research also tried to prepare recommendations to improve the CM deliver system focusing on the 'Method of CM Fee Estimation' and Selection of a CM firm as an owner's agent.

수답에서 2-(4-(6-chloro-2-benz-oxazolyloxy)phenoxy)-N-phenylpropionamide 유도체 중 N-phenyl 치환체들의 제초활성

A new fourty six 2-(4-(6-chloro-2-benzoxazolyloxy)phenoxy)-N-phenylpro- pionamide derivatives were synthesized and the herbicidal activities against rice plant and barnyard grass with pre-emergence in down land were measured. The structure activity relationships (SAR) between the activities and physicochemical parameters of the substituted(X) N-phenyl group in substrates were analyzed and discussed by Free- Wilson and Hansch method from the basis on the former study (Sung. et. al., 1999). The conditions of selective herbicide activity both the barnyard grass and rice plant are shown that the optimal bydrophobicity, (π)<SUB>opt</SUB>.=1.34 and electron donating with field effect (F<0) of meta and ortho, para-substituted mono or disubstituent on the N-phenyl ring were found to contribute significantly. The herbicidal activities against barnyard grass are roughly the same as the results in up land whereas damage to rice plant in down land more increase than that of up land. Degradation products in water are 2-(4-6-chloro-2-benzoxazolyloxy)phenoxy)propionic acid ((A)) (obs. pKa=4.35 & obs. logP=4.77) and 6-chloro-2-benzoxazolone (B) (obs. pKa=8.40 & obs. logP=2.90). These results were supposing that the hydrolysis product of substrates, (A) is comparatively absorbed in rice plant but not in barnyard grass. And it is assumed from the SAR equations that the 2,6-dimethyl-4-methoxymethyl group substituent (pI??=5.41, 3g/㏊) is selected as the most highest herbicidal acitvity against barngard grass in green house.

유기농 녹차의 등급별 총페놀 함량과 항산화능은 각 추출 용매에 따른 수율을 확인하였을 때 물 추출에 비하여 수용성 유기용매의 추출 수율이 유의적으로 높았다. 유기용매를 이용한 추출수율은 물을 이용할 때 보다 총페놀 함량은 1.5에서 3.2배, 항산화능은 1.8에서 3.8배 정도 높게 나타났다. HPLC 분석을 통하여 총페놀 함량과 항산화능의 상관관계를 비교 시 총페놀 함량이 증가함에 따라 항산화능이 1차 선형관계로 증가하는 경향을 보였다. HPLC분석을 통하여 유기농 녹차에 함유되어 있는 다양한 카테킨의 함량이 채엽시기에 따라 변화가 나타났다. 유기농 녹차의 카테킨 성분 중 가장 많이 존재하는 EGCG가 건조중량당 5.8-7.7%의 함량을 보였고, caffeine은 1.7-2.9%의 함량을 보였다. 유기농 녹차의 카테킨 함량은 일반적으로 채엽 시기가 늦어짐에 따라서 점차 감소하였다. 유기농 녹차의 등급에 따른 항산화능은 최상급인 우전에서 가장 높았으며 최하등급인 엽차에서 가장 낮게 나타났다. HPLC 분석에 의한 유기농 녹차의 등급에 따른 총 카테킨 함량(㎎/g)은 우전(155.4), 세작(147.7), 중작(143.2), 엽차(135.1), 대작(130.5)의 순서로 감소하였다. 이를 통해 녹차의 채엽 시기가 유기농 녹차의 카테킨 성분 및 항산화능에도 영향을 미치는 것을 확인하였다. 전반적으로 상급의 유기농 녹차 일수록 총페놀 및 카테킨 함량이 많으며 또한 더 높은 항산화능을 가지는 것으로 나타났다. The objective of this study was to evaluate the effect of various solvents on extraction of bioactive phenolics and to analyze the antioxidant capacity and contents of individual catechins in various grades of green teas organically grown in Boseong, Korea. The organic green teas, based on their harvest seasons, were categorized into five grades such as Woo-Jeon, Se-Jak, Jung-Jak, Dae-Jak, and coarse tea. Solvents used to extract phenolics from these teas included water at 23℃ and 70℃ as well as 80% (v/v) aqueous methanol and ethanol. In general, aqueous organic solvents of methanol and ethanol led to higher extraction yields of phenolics than water at 23℃ and 70℃. Total phenolics and antioxidant capacity of the teas extracted with the aqueous organic solvents were approximately 1.5 to 3.2 and 1.8 to 3.8 times higher than those with water at 23℃ and 70℃, respectively. Coarse tea, the lowest grade of green tea, showed approximately 30-60% lower total phenolics and antioxidant capacity compared with the higher grade ones. Reversed-phase HPLC analysis was performed quantitatively to identify individual catechins, gallic acid, and caffeine in teas extracted with 80% (v/v) aqueous methanol. Based on their dry weights, the organic green teas contained about 1.7 to 2.9% of caffeine. Content (㎎/g dry weight) of tea catechins decreased in the following order: Woo-Jeon (155.4) > Se-Jak (147.7) > Jung-Jak (143.2) > coarse tea (135.1) > Dae-Jak (130.5). (-)-Epigall℃atechin gallate was the most abundant among the catechins analyzed. The highest grade of green tea, Woo-Jeon, had the highest amount of (-)-epigall℃atechin gallate at 77.4 ㎎/g dry weight. Overall, the higher grade of organic green teas tended to have the higher level of antioxidant capacity and catechins.

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.

북한의 대남테러리즘 분석과 향후전망

이대성(Lee, Dae Sung) 한국테러학회 2012 한국테러학회보 Vol.5 No.1

김일성은 1958년 무력으로 최고인민회의를 점령한 후, 김두봉 등과 같은 외세 의존세력을 모두 숙청함으로써 1인 독재체제의 기틀을 마련하였고, 마르크스·레닌주의를 계승한 주체사상으로 1인 독재체제의 사상적 기반을 강화하였으며, 이를 통하여 영도적 수령체제를 구축하였다. 김정일은 김일성의 장남으로 1961년 7월 조선노동당에 입당한 후, 1970년대부터 경쟁관계에 있던 숙부 김영주를 실각시키고, 이복동생 김평일을 제거하였다. 김정일은 1980년 제6차 당(黨)대회를 통하여 김일성의 공식적인 후계자가 되었고, 1991년 12월 조선인민군 최고사령관직에 취임함으로써 2대 권력세습체제를 공고히 하였다. 1994년 김일성 사망 이후, 유훈통치 기간을 통하여 실질적 권력을 장악하여 제1통치자가 되었다. 김정일은 2010년 10월 10일 노동당 창건 제65주년 기념일에 김일성·김정일의 세습체제를 계승할 후계자 김정은을 화려하게 등장시킨 후, 2012년 12월17일 갑자기 사망하였다. 현재 북한은 국제사회에서 유래(由來)를 찾아 볼 수 없는 김일성·김정일·김정은 3대 봉건세습체제를 계승하려는 특수한 집단으로 전락하였다. 이러한 북한은 남북 분단 이후부터 최근까지, 한국을 대상으로 국가지원테러리즘을 지속적으로 자행하였기 때문에 향후 북한의 대남 테러리즘에 관심을 가져야 할 것이다. 이 연구에서는 북한 테러리즘을 이론적으로 검토하고, 김일성과 김정일 집권기에 한국을 대상으로 자행한 테러리즘을 구분하여 분석함으로써, 김정은 집권기에 발생 가능한 대남 테러리즘을 전망하고자 한다. Kim Il-sung had been the absolute power in North Korea from September 1948 to his death, which happened on July 8, 1994. Kim Il-sung brought about Korean War based on his misconception that many people would support for North Korea because of despotism of Lee Seung-man in South Korea and military supplies and armors he secured from Russian's military supports. Although he was one of those who should be responsible for Korean War, he blamed Park Heon-young of Namrodang, Mujeon of Yeonanpa and Heo Ga-i of Soryeonpa. He dominated Supreme People's Assembly by force in 1958 and purged all foreign country dependent groups including Kim Du-bong to secure his single dictatorship. He enforced the ideology of the single dictatorship based on 'Juche' Idea succeeding to Marxism and Leninism, and constructed so called 'Leading Suryeong' system. Kim Jong-il is the first son of Kim Il-sung. He entered Chosun Nodongdang(labor party in North Korea) in July, 1961, defeated his uncle Kim Young-ju and removed his half-brother Kim Pyung-il in the power game. He became the official successor of Kim Il-sung at the 6th Annual Conference of Nodongdang and secured the 'Two Generation Power Transfer' by taking the office of the Supreme Commander of North Korean People's Army in December. He seized the actual power through 'Precepts Ruling' period after the death of Kim Il-sung in 1994 and became the supreme ruler. He introduced his successor Kim Jong-un who would rule North Korea succeeding Kim Il-sung and Kim Jong-il himself on the 65th anniversary of Nodongdang on October 10, 2010, and died suddenly on December 17, 2012. Currently, North Korea is despised as an peculiar group to practice three generation power transfer such as Kim Il-sung, Kim Jong-il and Kim Jong-un, which could not be found in any other country. As the very North Korea has been executing terrorism against South Korea with the support of their government, terrorism of North Korea against South Korea should be reviewed and studied. In this study, it was tried to prospect the terrorism against South Korea which could occur during Kim Jong-un era by reviewing North Korean terrorism theoretically and analyzing terrorisms by classifying them as Kim Il-sung era and Kim Jong-il era.
