The Oecophoridae is a mega-diverse microlepidopteran family within the Gelechioidea (Lepidoptera) comprising more than 3,300 described and numerous undescribed species. Based on comprehensive phylogenetic analysis using eight genes for 82 taxa, the results indicated that (i) Casmara, Tyrolimnas and Pseudodoxia did not belong to Oecophoridae; (ii) other oecophorids dividing into two subfamilies, Pleurotinae and Oecophorinae, were nested within the same clade, and (iii) Martyringa, Acryptolechia and Periacmini were clustered with core Xyloryctide. Reconstruction of ancestral microhabitat of oecophorids indicated that they might have evolved from dried plant feeders and further convergently specialized. The ancestral larva sheltering strategy of oecophorids might have used a silk tube by making itself, shifting from mining leaves.

The sweetpotato whitefly Bemisia tabaci (Gennadius) is a serious pest and vector of various virus causing economic losses in a variety of vegetables in Bangladesh as well as worldwide. In the present study, the mtCOI sequence of B. tabaci was analysed using 70 samples collected from different host plants at 12 districts of Bangladesh. Phylogenetic analysis was shown genetic divergence of our samples was 0.12 – 13.97%. There was three independent clusters such as Asia I, Asia II-1 and Asia II-5 genetic groups. Sequence diversity among three groups was 13.97%, 15.07% and 9.67%. Geographic diversity, for example, Asia I distributed in Central and Northern parts, Asia II-5 Central and Southern parts but Asia II-1 were present everywhere in Bangladesh. There was no B and Q aggressive biotypes in Bangladesh. Most Asia I and II was distributed in southeastern countries including Thailand, Vietnam, Pakistan, China and India. Our results provide understanding of genetic diversity of B. tabaci in southeast area.

We report a spatial uctuation analysis of the sky brightness in the near-infrared from observations towards the north ecliptic pole (NEP) by AKARI at 2.4 and 3.2 μm. As a follow up study of our previous work on the Monitor eld of AKARI, we used NEP deep survey data, which covered a circular area of about 0.4 square degrees, in order to extend uctuation analysis at angular scales up to 1000". After pre-processing, additional correction procedures were done to correct time varying components and instrumental effects such as MUXbleed. To remove resolved objects, we applied 2α clipping and point spread function (PSF) subtraction. We finally obtained mosaicked images which can be used for the study of various diffuse emissions in the near-infrared sky and found that there are spatial structures in the mosaicked images using a power spectrum analysis.

The result of the previous work leads to the idea that the inner area of the hyperbolic shell generator should be minimized for the cooling tower with higher first natural frequency. In this study the inner area of the hyperbolic shell generator was graphically established under varying height of the throat and angle of the base lintel. From the graph, several shell geometries were selected and analysed in the aspect of the natural frequency. Three representative towers reinforced differently due to different first natural frequencies were analysed non-linearly and evaluated using a damage indicator based on the change of natural frequencies. The results demonstrated that the damage behaviour of the tower reinforced higher due to a lower first natural frequency was not necessarily advantageous than the others

This essay is a reflection on the significance of U.S. accountability to the struggles of Jeju Islanders for reparations. Under international law, a strong case can be made for the United States’ obligation to acknowledge its role in the Jeju atrocities and to provide compensation to the victims.1 Addressing the United States’ responsibility for complicity in these actions will prove controversial, no doubt, for it has significant implications not for U.S. actions in other parts of the world but for all states engaged in military occupations or acting through surrogate governments. These legal and political ramifications diminish the likelihood of voluntary remedial action by the United States, and the international legal system is ill-suited to compel compliance. Nonetheless, even if Jeju Islanders are ultimately unable to obtain full satisfaction from the United States government for its role in the atrocities to which they have been subjected, I believe that recognition of the international legal obligations incurred by the U.S. in that process can reinforce the legitimacy of their claims, thereby aiding in the restoration of their dignity and supporting their on-going struggles for self-determination.

We performed Principle Component Analysis (PCA) over 264 galaxies in the IRAS Revised Bright Galaxy Sample (Sanders et al., 2003) using 12, 25, 60 and 100 μm ux data observed by IRAS and 9, 18, 65, 90 and 140 μm ux data observed by AKARI. We found that (i)the first principle component was largely contributed by infrared to visible ux ratio, (ii)the second principal component was largely contributed by the ux ratio between IRAS and AKARI, (iii)the third principle component was largely contributed by infrared colors.

Combining the AKARI Point Source Catalog and the 37-month Monitor of All-sky X-ray Image (MAXI) catalog, the infrared and X-ray properties of nearby active galactic nuclei were investigated. The 37-month MAXI catalog tabulates 100 nearby Seyfert galaxies, 73 of which are categorized into Seyfert I galaxies. Among these Seyfert galaxies, 69 ones were found to have an AKARI infrared counterpart. For the Seyfert I galaxies in this sample, a well-known correlation was found between the infrared and X-ray luminosities. However, the observed X-ray luminosity of the Seyfert II galaxies tends to be lower for the infrared luminosity than the Seyfert I galaxies. This suggests that the X-ray absorption is significant in the Seyfert II galaxies. The Seyfert II galaxies seem to have a bimodal distribution of the IR color between 18 μm and 90 μm. Especially, a large fraction of the Seyfert II galaxies exhibits a redder IR color than the Seyfert I galaxies. A possible origin of the redder IR color is brie y discussed, in relation to the star formation activity in the host galaxy, and to the X-ray absorption.

The knock-in efficiency in the fibroblast is very important to produce transgenic domestic animal using nuclear transfer. In this research, we constructed three kinds of different knock-in vectors to study the efficiency of knock-in depending on structure of knock-in vector with different size of homologous arm on the β-casein gene locus in the somatic cells; DT-A_cEndo Knock-in vector, DT-A_tEndo Knock-in vector I, and DT-A_tEndo Knock-in vector II. The knock-in vector consists of 4.8 kb or 1.06 kb of 5’ arm region and 1.8 kb or 0.64 kb of 3’ arm region, and neomycin resistance gene(neor) as a positive selection marker gene. The cEndo Knock-in vector had 4.8 kb and 1.8 kb homologous arm. The tEndo Knock-in vector I had 1.06 kb and 0.64 kb homologous arm and tEndo Knock-in vector II had 1.06 kb and 1.8 kb homologous arm. To express endostatin gene as transgene, the F2A sequence was fused to the 5’ terminal of endostatin gene and inserted into exon 7 of the β-casein gene. The knock-in vector and TALEN were introduced into the bovine fibroblast by electroporation. The knock-in efficiencies of cEndo, tEndo I, and tEndo II vector were 4.6%, 2.2% and 4.8%, respectively. These results indicated that size of 3’ arm in the knock-in vector is important for TALEN-mediated homologous recombination in the fibroblast. In conclusion, our knock-in system may help to create transgenic dairy cattle expressing human endostatin protein via the endogenous expression system of the bovine β-casein gene in the mammary gland.

본 논문은 위르겐 몰트만의 교회 이해와 선교 이해를 탐구한다. 몰트만에게 있어서 교회는 우선 삼위일체적 공동체이다. 몰트만은 기독교 고유의 하나님은 삼위일체적 하나님임을 강조한다. 성부와 성자와 성령의 삼위일체는 역동적 침투와 상호 내주를 의미하는 페리코 레시스의 관계성 속에 있는 공동체로 존재한다. 동등한 신적 삼위는 획일성이나 개인주의가 없는 페리코레시스적 공동체와 사귐을 형성한 다. 몰트만은 이것을 사회적 삼위일체라고 부른다. 삼위일체 하나님은 또한 열린 공동체로 존재한다. 하나님은 자신의 삼위일체적 공동체를 열어 피조물들 속으로 들어가고 또한 피조물들이 삼위일체의 사귐과 삶에 참여하도록 초청한다. 몰트만은 이러한 삼위일체는 교회의 모델 또는 모형이 된다고 주장한다. 이러한 관점을 바탕으로 몰트만은 위계 질서적이고 관료적인 교회 형태로부터 회중적이고 공동체적인 교회에 로의 교회 개혁을 강조한다. 그리고 교회는 사적인 공동체로만 머무는 것이 아니라 자신을 개방하여 공적 영역으로 나아가야 함을 제안하다. 몰트만은 또한 교회를 메시아적 공동체로 해석한다. 교회는 예수 그리스도의 교회이다. 교회는 무엇보다 종말론적 비전과 생명의 영이신 성령의 능력 안에서 그리스도의 뒤를 따라 모든 피조물들의 생명의 해방을 위해 일해야 하는 공동체이다. 이러한 교회론을 바탕으로 몰트만은 기독교 선교에 대한 그의 새로운 통찰을 발전시킨다. 그는 교회는 선교적 교회가 되어야 한다고 논한다. 그에게 있어서 선교는 기독교 제국의 팽창이나 기독교 교회의 확장이나 온 인류의 복음화이기 보다는 생명에로의 초대이다. 그는 또한 선교를 사람들과 사회와 모든 피조물들의 해방을 위한 사역으로 이해한다. 몰트만에게 있어서, 선교의 지평은 하나님의 나라의 관점에 서 계속 넓게 개방된다. 그것이 지향하는 바는 하나님이 모든 것 속의 모든 것이 되실 때 성취될 새 창조의 종말론적 완성이다. 그러므로 몰트만의 선교론은 에큐메니칼적이고 총체적인 특징을 가진다. 제2차 바티칸공의회의 교회론과 부산에서 열린 제10차 WCC 총회가 발표한 새로운 선교 비전 선언문과 상응하면서, 몰트만은 위기 가운데 있는 현대 교회들의 미래를 위한 새롭고 적합한 선교의 방향을 제시하고 있는 것이다.

Due to a lack of the hoop action of lateral reinforcements the effective confining force in rectangular sections reduces compared to circular ones. Therefore, the stress-strain model obtained from the experimental data with circular sections overestimates the lateral confinement effect in rectangular sections, which evaluates seismic safety margin of overall structural system excessively. In this study experiments with laterally-confined square sections have been performed and the characteristic values composing stress-strain model have been analyzed. With introduction of section coefficients, in addition, the new unified stress-strain model applicable to square sections as well as circular ones has been proposed.

본 연구에서는 우리나라에 번식하는 올빼미의 실질적인 행동권 파악을 통해 멸종위기야생동물 II급 올빼미의 생태적 특성을 규명하여 올빼미 개체군을 보호하고 보전하며 관리하는데 필요한 자료를 제공하고자 ‘자연환경보전법’에 따라 시행하고 있는 제 4차 전국자연환경조사의 일환으로 2016년 4월 14일~5월 20일까지 번식기 육추시기에 약 한달 간 진행했다. 그 결과 경북 일대에서 전장(Total Length) 423.5㎜ 와 무게 550g 의 암컷 1개체를 포획하였고 우리나라 최초로 추적에 성공했으며 직접관찰과 위성추적 관찰 좌표 6지점을 획득 하였다. 가장 먼 지점의 거리는 둥지로부터 93m의 이격 거리였다. 그리고 육추시기에 약 100m 반경에 대한 서식지 분석결과 밭 34.2%, 혼효림 30.6%, 과수원 10.5%, 자연초지 9.4% 순의로 토지피복도 우점 순위가 나타났다. 이는 이전의 연구결과와 매우 유사한 결과로 향후 수컷 또는 다른 개체들에 대한 추적조사를 바탕으로 추가 연구가 이루어져 멸종위기야생동물 II급 올빼미의 보호와 보전하는데 기초자료로서 활용을 기대한다.

환경부 지정 멸종위기 II급 종인 남생이의 복원을 위하여 개체증식 프로그램들을 개발해왔지만, 남생이의 번식생리에 대한 이해는 여전히 부족한 상태이다. 본 연구에서는 2014년 11월부터 2015년 10월 사이에 동면을 한 개체와 동면을 하지 않은 개체를 이용하여 성호르몬, 여포와 알의 수와 크기, 암ž수간의 행동상호작용의 계절적 변화를 연구하였다. 비록 동면 여부에 따라 다소의 편차는 있었지만, 암컷의 혈청 에스트라디올 농도는 7월부터 증가하기 시작하여 8월-10 월에 최고 농도를 보였으며, 수컷의 테스토스테론의 농도는 8-9월에 최고 농도를 보였으며, 3월에 가장 낮았다. 동면을 한 암컷들은 5월초에서 7월 중순 사이에 완전히 발달한 알을 가지고 있었으며, 산란은 6월 초순부터 7월 하순 사이에 이루어졌다. 반면, 동면을 하지 않은 암컷들은 이른 4월부터 이른 6월 사이와 8월 중순에서 11월 하순 사이에 알을 가지고 있었으며, 산란은 6월초, 10월 중순, 2월 초에 이루어졌다. 이러한 결과는 동면이 여포와 알의 정상적인 발달에 매우 중요한 역할을 함을 보여준다. 행동연구에서 암ž수간의 구애행동을 포함하는 행동상호작용은 8월 하순부터 증가되 어 10-11월에 최대를 보였다. 연구결과는 남생이의 짝짓기 기간이 성호르몬의 증가와 직접 연계되어 있지만, 여포와 알의 발달은 그렇지 않다는 것을 보여준다. 이러한 연구결과는 멸종위기종인 남생이의 성공적인 번식프로그램을 운영 하는데 매우 중요하게 사용될 것으로 판단된다.

Coagulation/precipitation process has been widely used for the removal of phosphate within domestic wastewater. Although Fe and Al are typical coagulants used for phosphate removal, these have some shortages such as color problem and low sedimentation velocity. In this study, both Fe and Al were used to overcome the shortages caused by using single one, and anionic polymer coagulant was additionally used to enhance sedimentation velocity of the precipitate formed. Batch experiments using a jar test were conducted with real wastewater, which was an effluent of the second sedimentation tank in domestic wastewater treatment plant. Response Surface Methodology was used to examine the responsibility of each parameter on phosphate removal as well as to optimize the dosage of the three coagulants. Economic analysis was also done on the basis of selling prices of the coagulants in the field. Phosphate removal efficiency of Fe(III) was 30% higher than those of Fe(II). Considering chemical price, optimum dosage for achieving residual phosphate concentration below 0.2 mg/L were determined to be 18.14 mg/L of Fe(III), 2.60 mg/L of Al, and 1.64 mg/L of polymer coagulant.

Seismic design of braced frames that simultaneously considers economic issues and structural performance represents a rather complicated engineering problem, and therefore, a systematic and well-established methodology is needed. This study proposes a multi-objective seismic design method for an inverted V-braced frame with suspended zipper struts that uses the non-dominated sorting genetic algorithm-II(NSGA-II). The structural weight and the maximum inter-story drift ratio as the objective functions are simultaneously minimized to optimize the cost and seismic performance of the structure. To investigate which of strength- and performance-based design criteria for braced frames is the critical design condition, the constraint conditions on the two design methods are simultaneously considered (i.e. the constraint conditions based on the strength and plastic deformation of members). The linear static analysis method and the nonlinear static analysis method are adopted to check the strength- and plastic deformation-based design constraints, respectively. The proposed optimal method are applied to three- and six-story steel frame examples, and the solutions improved for the considered objective functions were found.

The objective of this study was to investigate ELF-MF exposure levels in infant living environmental spaces at daycare centers. To achieve the objective of the study, we surveyed ELF-MF levels using EMDEX II at daycare centers from October 2013 to October 2014. The ELF-MF level of 53 daycare centers in terms of arithmetic mean (AM) and geometric mean (GM) were 0.59 ± 0.76 mG and 0.33 mG, respectively. And the ELF-MF level of 260 daycare center classrooms was 0.50 ± 0.71 mG (GM: 0.28 mG). The exposure levels of ELF-MF for all daycare centers were far below the recommended standards cited in guidelines in Korea (833 mG) and international reference levels proposed by WHO or ICNIRP (2,000 mG). Furthermore, we discovered out that as distance increased, ELF-MF emission levels decreased significantly in all electrical instruments. Below the 2 mG ELF-MF levels when an electrical instrument moved away stage 1 (Grade). Thus, these results will provide useful data for the determination of ELF-MF management and reduction methods at infant daycare centers.

The objective of this study was to determine the growth and light utilization efficiency of garden plants in shade area through chlorophyll fluorescence reaction analysis. Ten garden plants was grown for 75 days under 50% and 80% shading conditions. Under shading, ET2O/RC, the fluorescence parameter related to electron-transport in photosystem II, was effectively enhanced. However, the electron transport flux until PSI acceptors per reaction center (RE1O/RC) was reduced. These changes in photochemical parameters evoked a decrease in performance index (PI) and driving force (DF) of electron transport flux. In addition, some photochemical parameters such as FV, FV/FO, RE1O/RC, ET2O/RC, PITOTAL ABS, and DFTOTAL ABS were found to be important for shade tolerance. Three species (Pachysandra terminalis Siebold & Zucc, Physostegia virginiana L., and Carex maculata Bott) were found to be shade tolerant. Based on these results, shading factor index (SFI) deduced from photochemical parameters is useful for evaluating of shading stress of garden plants.

Shiga toxin-producing Escherichia coli (STEC) is a major foodborne bacterial pathogen that causes many zoonotic diseases such as mild diarrhea, hemorrhagic colitis, and a life-threatening hemolytic uremic syndrome. STEC produces one or more Shiga toxins (Stxs) with or without other virulence factors including the locus of enterocyte and effacement pathogenicity island and the 60-MDa plasmid. Because cattle are the principal reservoirs of STEC, the consumption of undercooked meat and dairy products contaminated with bovine feces is the most common transmission route of STEC in human infections. To understand the epidemiology of STEC infection in South Korea, the prevalence of STEC among bovine feces, meat products, and human patients was reviewed in this study. We found that (i) the prevalence of STEC O157:H7 (hereafter referred to as O157 STEC) isolates was generally decreased, whereas non-O157 STEC isolates be increased among bovine feces and meat products from 2000 to 2012 and (ii) no severe human outbreaks occurred. Instead, 50 to 100 sporadic cases of STEC infection per year have been reported in asymptomatic human patients or patients with mild diarrhea. Key words: Shiga toxin-producing, Escherichia coli, STEC, prevalence, South Korea

본 논문은 외르크 임멘도르프(Jörg Immendorff, 1945-2007)의 회화 <카페 도이칠랜 드 Café Deutschland>(1978-1982) 연작에 나타난 임멘도르프의 자화상을 통해 당대 독 일의 시대상을 알아 볼 수 있는 연구이다. 임멘도르프는 독일 서독 태생의 작가이며 신 표현주의(Neo-expressionism) 화파의 대표적인 화가이다. 임멘도르프는 뒤셀도르프 아 카데미(Düsseldorff Academy)시절 스승인 요셉 보이스(Joseph Beuys, 1921-1986)로부 터 서독 자본주의와 물질주의의 지배에 대한 비판의식에 강한 자극을 받아 서독 자본주 의 이면에 팽배한 모순적 현상에 대해 주목하게 된다. 이러한 의식 아래 임멘도르프는 정형화된 예술에서 탈피하여 다양한 기존 사회 체제를 비판하는 반(反)예술 성향의 사 회 운동가적 퍼포먼스를 펼치며 대중사회에 자신의 이념을 전달하였다. 또한 임멘도르 프는 분단된 독일 사회에도 깊은 관심을 가지고 1976년부터 동독 작가 펭크(A.R.Penck, 1939-)와 교류하게 되었다. 이후 1978년을 기점으로 회화 <카페 도이칠랜드>에서 냉전 후 동독과 서독으로 분리된 혼란한 독일의 모습을 혼잡한 카페(café)라는 독일 사회의 축소판으로 설정하였다. 이렇듯 임멘도르프는 사회적 문제점들을 다양한 상징적 요소들 을 사용함으로써 예술이 사회 변혁을 이룰 수 있는 도구로 보았으며, 예술과 사회가 통 합된 삶을 이룩하기를 원하는 일종의 사회적 예술가의 사명감을 가지고 있었다. 또한 임멘도르프는 <카페 도이칠랜드>의 역사적 함의를 강조하기위해 실제 당대 독일에서 일어난 사건들을 겪은 본인의 자화상을 다양한 모습으로 <카페 도이칠랜드>에 표현했 다. 이와 같은 점은 <카페 도이칠랜드>가 시대상을 투영함으로써 역사적 가치를 가지는 동시에 그 시대를 직접 경험한 임멘도르프 개인의 일대기적인 회화라고도 볼 수 있다. 따라서 임멘도르프는 <카페 도이칠랜드>에 다양한 본인의 자화상을 직접적으로 화면에 등장시킴으로써 그가 예술가로서 실행할 수 있는 정치, 사회적 역할에 대한 깊은 고심과 사회의 부조리에 맞서는 모습들을 캔버스에 생생히 표출했다고 볼 수 있다.

This study investigated the effects of the Mercedes Model with Embedded Assessment Strategy, subject specialisation and gender on students’ knowledge of selected biology concepts. A pretest post-test control group quasi-experimental research design was adopted for the study. The sample consisted of 666 Senior Secondary Class II biology students from six senior secondary schools randomly selected from two purposively selected Education Districts (EDs) in Lagos State. The two EDs were randomly assigned to treatment such that one was the experimental group and the other the control group. Seven null hypotheses were formulated to guide the study. Also, five instruments were used to generate data for the study, namely, the Mercedes Model with Embedded Assessment Strategy in Diffusion (MEASID), Mercedes Model with Embedded Assessment Strategy in Osmosis (MEASIO). Conventional Lesson Plan on Diffusion (COLPOD), Conventional Lesson Plan on Osmosis (COLPO) and Test on Students’ Learning Outcomes in Osmosis and Diffusion (TESLOOD). Data collected were analysed using mean, standard deviation, analysis of covariance (ANCOVA) and multiple classification analysis. The study has shown that the use of the Mercedes Model with Embedded Assessment Strategy has positively improved students’ knowledge of selected biology concepts. Further, the biology students in the science class were better than the non-science group at imbibing the knowledge of biology concepts. In the same vein, the males performed better than their female counterparts in knowledge. It was recommended, among other things, that teachers of biology adopt the Mercedes Model with Embedded Assessment Strategy in the teaching of students in secondary school.

이 글은 1733년, 바흐와 첼렌카가 드레스덴 궁정의 선제후로부터 하사받은 교회작곡가라는 직책에서부터 시작한다. 18세기 전반부 독일어권의 바로크 음악문화에서 이러한 명칭은 당대의 관습과 전통을 드러내는 표식이라는 논의를 거친 후, 드레스덴 궁정과 이곳의 음악가, 그리고 이곳을 다스리던 프리드리히 아우구스트 2세로 관심을 이동시킨다. 이 궁정의 음악문화가 드러내는 특징과 성격을 프리드리히 아우구스트 2세의 친이탈리아적인 성향과 연계지어 설명한 후, 이 글은 이러한 이유로 인하여 바흐와 첼렌카는 선제후의 주목을 받지 못했다고 규정하며, 이것이 작센지역에서 살아가던 작곡가들이 경험하고 부딪히고 관계 맺던 당대의 음악적 문맥임을 역설하고 있다.
