Purpose: To evaluate the effects of conjugated hormone replacement therapy (HRT) on dry eye syndrome in postmenopausal women. Methods: Thirty-six healthy postmenopausal women (72 eyes) were included in this three- month prospective study. Schirmer test, tear film break-up time (BUT), fluorescein staining score and symptom score were performed on all patients at the time of enrollment, one month and three months after initiation of HRT. All patients received HRT consisting of conjugated estrogen and progesterone taken orally in a continuous combined regimen. Results: Symptom score significantly decreased from 2.10±0.79 before HRT to 1.32±0.84 after one month and to 0.88±0.67 after three months (p<0.001). In addition, tear film BUT measurements significantly increased from 6.04±2.54 seconds to 7.99±2.43 seconds after one month and to 8.93±2.20 after three months (p<0.001). The fluorescein staining score was 0.94±0.71 before HRT and decreased to 0.42±0.60 after one month and to 0.22±0.42 after three months (p<0.001). Conclusions: Hormone replacement therapy consisting of conjugated estrogen and progesterone significantly improved the symptoms and signs of dry eye syndrome in postmenopausal women.

The aim of this study was to analysis the landscape equipments of 42 school gardens in Taejon metropolitan city. Outdoor educational landscape equipments were found out at 10 schools out of 42 schools. The materials of main entrance were consisted of steel and stone at 19 schools. The stands at front of the main ground were existed at 21 schools. The pergolas and benches were existed at 20 schools. The living material fences were found out at 21 schools. Plant nameplates were found out at 22 schools. But the contents of the nameplates were so poor. The wetland and roof garden of the school were not existed. School landscape equipments should be introduced by the distinction of elementary school, middle school, and high school as well as by the space of the school site.

생체인증을 위한 프라이버시 중심 설계와 보안사용성에 대한 연구

최근 편리하고 안전한 생체인증 기술이 핀테크 서비스의 필수 구성요소가 되고 있다. 그러나 생체 인증의 보안성과 정확도 향상을 위해 많은 양의 생체 정보를 활용한다면 연산과정이 복잡해져서 속도 저하와 개인정보 유출 가능성이 높아지고, 실시간성을 제공하기 위해 생체 정보의 일부만 샘플링하여 활용하는 경우에는 보안성과 정확도가 열화되는 Trade-off 문제가 있다. 종래의 생체인증 기술은 메타데이터를 이용한 필터링의 경우 데이터 간의 상관성이 고려하지 않아서 개인정보보호와 사용자 편의성에 한계가 있었다. 본 연구에서는 상관성 높은 데이터를 활용하여 프라이버시 중심의 생체인증 설계와 보안사용성을 향상시키는 방안을 제안한다.

The fast-growing agricultural biotechnology and rapidly increasing global area of transgenic crops every year have caused concern about human health and natural environment. Thus, the establishment of various techniques for the environmental risk assessment is necessary for the evaluation of transgenic plants. The objective of this study was to evaluate resveratrol-producing GM rice varieties such as Iksan515 and Iksan526 and non-transgenic rice varieties such as Dongjin and Nampyeong on insects fauna including spiders and bio-indicators. To compare with transgenic rice with non-transgenic rice plants, we cultivated both rice varieties in the confined fields and surveyed the occurrence and survivals of the insects and bio-indicators. The biosafety on bio-indicators was also investigated. When survival rate, host preference and abnormal response of Nilaparvata lugens adults were studied, there was no significant difference among the four rice varieties investigated. At the same time, there was no significant difference in abnormal response, immobility and survival rate of Misgurnus anguillicaudatus as well as immobility, weight and shell height of Pomacea canaliculata among the four rice varieties investigated. Overall, the results in this study indicated that the transgenic rice plants did not exert any hazardous impacts on insect diversities, natural enemies, and bio-indicators in both of laboratory and natural conditions.

용체화처리한 AZ91-X%Sn 마그네슘 합금의 부식 저항성 변화

문정현 ( Jung Hyun Moon ),전중환 ( Joong Hwan Jun ) 한국열처리공학회 2015 熱處理工學會誌 Vol.28 No.5

The effects of Sn addition and solution treatment on corrosion behavior were studied in AZ91 magnesium casting alloy. The addition of 5%Sn contributed to the introduction of Mg2Sn phase, to the reduction in dendritic cell size and to the increase in the amount of secondary phases. After the solution treatment, trace amount of Al8Mn5 particles were observed in the α-(Mg) matrix for the AZ91 alloy, while Mg2Sn phase with high thermal stability was additionally found in the AZ91-5%Sn alloy. Before the solution treatment, the AZ91-5%Sn alloy had better corrosion resistance than the Sn-free alloy, which is caused by the enhanced barrier effect of the (β + Mg2Sn) phases formed more continuously along the dendritic cell boundaries. It is interesting to note that after the solution treatment, the corrosion rate of both alloys became increased, but the Sn-added alloy showed higher corrosion rate than the Sn-free alloy. The microstructural examination on the corroded surfaces revealed that the remaining Mg2Sn particles in the solution-treated AZ91-5%Sn alloy play a role in accelerating corrosion by galvanic coupling with the α-(Mg) matrix.

<드래곤볼>에 재현된 주체의 탈식민적 양상 연구

문정현(Jung Hyun Moon) 한국애니메이션학회 2016 애니메이션연구 Vol.12 No.2

몇 몇의 암시적인 도상을 활용하여 긴장감 넘치는 서사를 구축해온 <드래곤볼>은 일본 근대사에 함축된 공동의 욕망 구조를 해석하기 적합한 만화 콘텐츠이다. 가령 인물의 원상태에서 초인으로의 변형 과정을 통한 지각 작용은 일본 근대 서사를 상징하는 메타포로서 탈식민주의 측면에서 중점적인 분석의 토대를 제공한다. 본 글은 손오공에게 순차적으로 발생하는 외형적 변화의 특성들을 사례로 제시하며 이미지가 지시하는 사회적 맥락과 잠재의식에 관해서 중점적으로 분석한다. 완전한 충족에 도달하지 못한 상징 기표들은 대중에게 익숙한 형태로 읽히지만 동시에 일시적이고 불완전한 형상으로 봉합되어 노출된다. 서양과 동양의 외형적 특성들이 교접하는 기호 형식의 층위에서 타자의 위치를 거부하고 새로운 주체성을 획득하려는 욕망은 외부의 신화적 요소들을 취합하며 재구성된다. 내면의 피지배적 구조는 적합한 상징을 포착하여 효과적인 외피로 응집되지만, 한편으로는 불안정한 잠재구조를 여과 없이 투사하는 형상으로 재현되며 은폐된 수동적 가학성을 노출한다. 이처럼 양가적인 감정을 초래하는 심층구조는 잠재된 소망을 현실의 기형적인 지시대상으로 치환한다. 억압된 의식구조는 원형을 초극하는 이미지를 재현하며 매 순간 분투한다. 강제적인 외세의 국호 개방으로 굴곡진 <드래곤볼>의 표상체계들을 훑으며 본 글은 비가시적 욕망의 양식과 기호들을 재추적하는 동시에 변형된 이미지가 지시하는 무의식적 지층을 밝히고자 한다. 또한 작품에서 재현되는 도상적인 상징들이 일본 내에서 폭넓은 공감대로 인지되는 데에 충족된 필요조건들을 나열하며 분석의 기틀을 제시할 것이다. 시대적 맥락에 따라 개념(concept)과 수용(conception)의 매개 관계로 파생되는 해석의 폭넓은 층위들을 연구하기 위함이다. The animation is the indisputable content that has been widely popularized and appreciated by a large number of people. Animation sometimes becomes the icon of the certain era when the population sympathize with the characters and the plot that stirs up their imagination. Animation image can be viewed as it meets the role of the media in order to speak for the unconscious desires of its society. However, the iconographic analysis of the comic images is an urgent task that needs to be examined. On the other hand, the concept and conception constantly change due to the context of the time. The postcolonial perspective on Dragon Ball criticizes and reveals a common appetite on the deep structure of Japan. In this paper, the purpose is to examine a potential image which indicates the layers of its unconsciousness. On behalf of Japanese comic industry, Dragon Ball is a significant content that provides the implied aspects of the common desire through a number of symbols, icons, and a dramatic narrative structure. In particular, the perception process that comes from the metamorphosis of the original character to the superhuman, functions as the metaphor for the self-awareness in modern Japan. The study is aiming to determine the invisible desire hailed as an icon of the metaphorical images. I hope the study would present a point of view to determine the post-colonial aspects of subject represented in Dragon Ball.

In this paper, we deal with the vehicle routing problem that could establish operational plan of military engineer for survivability support of artillery position construction. We propose VRPTW(vehicle routing problem with time-window) model of special form that considered service level to reflect the characteristics of military operations rather than the logic of economic efficiencies in the objective function. Furthermore we suggest modified particle swarm optimization algorithm for service based vehicle routing problem solution that can be possible to search in complicated and uncertain area and control relation softly between global and local search.
