한국 문화 전반에 성 평등을 주제로 한 페미니즘이 중요한 이슈로 연구 대상적 가치가 급상승하였다. 페미니즘 영화란 단지 여성의 권익을 주장하거나 옹호하는 차원의 수준이 아닌 과거 남성들이 창조한 스토리 속에서 대상화되거나 타자화 된 인물로 왜곡, 인위적으로 묘사되던 그릇된 여성의 모습이 아닌 시선과 사고의 본질적 주체로서 사회 속 개인의 삶의 문제를 근원적으로 탐구하는 영화라고 할 수 있다. 이와 같은 관점에서 전고운 감독의 영화 '소공녀(2018)'를 분석하였으며 영화 속에는 남성 편향적 고정관념과 불평등적 사회구조에도 주인공의 꿋꿋한 자기 선택과 초월적 사고를 보여주는 페미니즘 적인 주제를 표현하고 있음을 알 수 있었다. 대중영화가 세상에 대한 넓은 식견을 키우는 교육 계몽적 성격을 견지하고 성숙한 사회문화를 선도해야 한다는 관점에서 이와 같은 사회에 대한 전지적 통찰과 이상적 인간관에 대한 제고 등을 다룬 영화는 사회를 긍정적이고 이상적으로 바꾸는 데 큰 역할을 할 것이라고 생각된다.

Most domestic small rivers and streams due to industrialization and urbanization have managed by concrete structures. The environmental functions of the river and stream are disappearing and urban streams play only the role of drainage systems. Also, the researches to restore natural streams are something yet to develop and not established the restoration for ecological functions of a small stream. Therefore the researches are required to develop ecological engineering system for watershed management system to handle various pollutants with restoration for ecological functions of a small stream. To develop this, the ecological engineering system for watershed management system could be developed with ecological conservation. In addition, ecological engineering system for watershed management system should be prior to conserve the habitat of biological resources and water conservation and applied to the original shape of streams. Also, it should be designed to restore the micro-topography of stream, the habitat of plant population in watershed. It is needed to develop the integrated researches to restore a small stream ecosystem.

Mineral profile of serum and cerebrospinal fluid (CSF) of 15 Himalayan Yak (adult female, n=8; adult male n=4 and young male,n=3) was studied in their natural habitat at an altitude of 3300 meters above mean sea level at Sangla in north western Himalayas. The macro and micro minerals estimated in serum and CSF were; Sodium, Potassium, Calcium and Magnesium and Zinc, Copper and Iron respectively. The values recorded among different Yak groups did not significantly differ from each other except serum iron and haemoglobin which were significantly higher (p<0.05 ) in young male Yaks compared to the adult male and female Yaks. An observation of great significance was considerably higher potassium and lower sodium level in Yaks compared to other bovine species of plains. The serum potassium values in some adult female Yaks were recorded as high as 10.4 mEq/l and the values varied between 6.6 to 9.8 mEq/l in young male Yaks. The serum Sodium values and Na:K ratios in Yak serum ranged between 117.5 to 122.6 mEq/l and 13.7 to 15.3 respectively. The possible relationship of high serum Potassium value with hypoxic conditions and hostile mountain environment has been discussed.

While a concept on biotop or the urgency of its classification systems have been under discussion recently, this study aims to examine outdoor biotop classification systems for environment-friendly community. To this end, the feasibility of creating a biotop in the community and application elements were generated and biotops were classified and categorized. Then, elements that can be applied in consideration of traditional Korean techniques were generated and biotop classification systems and specific components in residential areas were reviewed. As for the result of this study, based on a preliminary draft prepared through literature review, considerations for biotop classification systems were taken into account. Then, based on classification criteria for biotop formats, biotop functions and biotop types, a second-tier classification system was developed. Criteria for biotop formats included surfaces, lines and points while criteria for biotop functions were large cores, small bases, corridors, stepping stones and ecological islands. Criteria for habitat types were divided to include natural forest, developed green areas, lacustrine wetland, palustrine wetland, shrubs, grasslands, linear habitats, vacant plots and practical green areas, which were sub-categorized. As for the biotop classification system, macro-classification divided biotops into three types-space, line and point-based on biotop formats. Meso-classification had five groups and micro-classification had 21 groups based on habitat types. Future studies should focus on the ecological features of each biotop categories generated in this study and their creation and management techniques to find many practical methods to create, protect and manage outdoor biotop for environment-friendly community.

논 습지는 다양한 야생동물들의 주요 서식공간으로, 급격한 개발 및 환경 변화로 인해 논에 서식하는 야생동물의 생물 다양성 보전에 위협이 되고 있다. 본 연구에서는 서해안에 위치한 논 습지를 이용하는 무미 양서류의 서식지 이용 특성을 규명하고자 2018년 3월부터 10월까지 당진시 대호 간척 농지에 서식하는 양서류의 풍부도와 서식 환경을 바탕으로 종들에게 영향을 끼친 주요 환경 요인을 파악하고, 서식지 이용 특성을 알아보았다. 연구 결과 조사지역에서는 금개구리(Pelophylax chosenicus)를 포함하여 참개구리 (P. nigromaculatus)와 청개구리 (Hyla japonica)의 서식이 확인되었다. 3종에 영향을 끼치는 환경 요인으로 기온과 습도, 수심, 미소 서식지로 확인되었고, 청개구리는 수온에 영향을 받고 있었으며, 금개구리는 벼의 길이와 농법의 유형에 영향을 받고 있는 것으로 확인되었다. 3종은 모두 기온과 습도, 수심이 증가할수록 개체수가 증가하는 경향을 보였고, 모내기한 필지를 가장 많이 이용했으며, 번식 시기에는 미소 서식지 요인 중 필지를 가장 선호하고 있어 조사지역이 3종의 주요 번식지로 이용되고 있는 것으로 판단된다. 금개구리는 관행에 비해 친환경 농지에서 더 많이 관찰되었는데, 이는 포식자와 제초작업으로 인한 주변 환경의 차이로 인한 원인으로 보인다. 본 연구를 통해 논에 서식하는 무미 양서류 3종이 선호하는 환경 요인은 종에 따라 다른 것을 확인할 수 있었다. 이 결과는 무미 양서류 보전에 중요한 자료를 제공할 것이다.

이석(otoliths)은 경골 어류의 내이(inner ear)에 존재하는 평형석으로 어류의 성장과 함께 성장하며, 이석 내 산소동위원소는 어류가 서식했던 수온에 영향을 받으며 침전되기 때문에 어류가 서식했던 서식처의 수온을 반영한다고 알려져 있다. 본 연구에서는 명태 이석 내 산소동위원소(${\delta}^{18}O$)와 서식 수온과의 관계를 조사하여, 명태의 생활사에 따른 서식지의 변동을 비교하였다. 우리나라와 일본의 동쪽 해역에서 $1997{\sim}1999$년 사이에 채집된 명태로부터 이석을 채취하여 연령대 별로 산소동위원소 함량을 분석하였으며, 수온 자료는 양국의 해양자료센터(KODC, JODC)로부터 획득하였다. 명태가 서식하는 수심의 수온은 가을과 겨울에 걸쳐 연중 가장 높았고, 우리나라 동해연안은 200 m 이상의 수심에서는 계절적 변동이 거의 없이 낮은 수온이 분포하는 안정된 상태였으나, 일본 해역에서는 300 m의 비교적 깊은 수심에서도 계절적 변화를 보였다. 전반적으로 모든 수심에서 우리나라 보다 일본 연안의 수온이 높았으며, 일본 해역의 명태가 우리나라 명태보다 깊은 곳에 서식하였다. 우리나라와 일본 명태 이석의 산소동위원소 값은 대부분 시료에서 이석의 핵 부분 보다는 가장자리 부분에서 산소동위원소 값이 높아 명태가 성장하면서 수온이 낮은 깊은 수심으로 이동하는 것으로 이해된다. 또한, 3년 동안의 수온변화와 그 당시 성장하였던 이석의 산소동위원소 값은 역상관 관계를 보이고 있다.

This paper discusses several topics associated with the densification caused by supertall buildings and their impact on city systems. The paper covers five key areas where a supertall tower creates a concentration of needs and effects. First, the paper comments on population shifts towards the city and how they affect carbon footprint, utilities infrastructure and transport. The effect of single- and mixed-use towers is discussed in the context of population density. The second section brings the issues of transit, accessibility and master planning into focus. The use and criticality of public transport, cycling and walking is described. Servicing and deliveries using freight consolidation and shared systems is also discussed along with their contribution to the culture of sustainable travel. In the third section the paper reflects on supertall buildings' below-ground utilities and drainage provision, particularly the challenges faced in established city infrastructures. The utilities issues associated with supertall concentration (in land-use terms) compared to equivalent low-rise distribution is also commented on in the context of surface water runoff. In the fourth section, the topic of supertall sustainability is discussed and how city systems need to respond to create desirable and affordable space for occupiers. The changing need for vertical communities, 'stacked neighbourhoods' and the notion of a micro-city is described. Finally, the paper considers the energy consumption and resilience of supertall buildings in the context of basic geometry, façade design, climate and mixed-use benefits as they impact city systems.

A variety of fish species undergo an ontogenetic change in prey selectivity, and several potentially interacting factors, including nutrient requirement, microhabitat change, and foraging ability, may account for the occurrence of the shift. Here we examine the foraging ecology and ontogenetic diet shift of a micro-carnivorous goby, Pterogobius elapoides (serpentine goby), dominant component of fish assemblage in shallow rocky areas off the coast in Korea and Japan. Although most other gobies are primarily benthic carnivores, P. elapoides is a semipelagic fish; however, little is known about how those species change their foraging tactics with growth. In our diet analyses, the most common diet was pelagic copepods and benthic amphipods, and diet shift was observed from pelagic to benthic with growth. The ontogenetic diet shift seems to be the result of the preference for energetically more profitable prey in larger-size classes as well as the results of different prey availability due to among-habitat variation in diet. However, differential food preference does not appear to affect individual scope for searching food. Several factors such as predation pressures and interspecific resource partitioning might contribute to the changes in diet observed among size classes, which were included in our ongoing tests.

Background: To understand the ecological characteristics of floating mat in which endangered species of Iris laevigata and Menyanthes trifoliata inhabit, we surveyed the vegetation and water environments of a floating mat wetland and examined the relations between ecological characteristics of the mat. Results: Although Phragmites australis and Zizania latifolia were found at all experimental quadrats (n = 61) as the major vegetational components of the floating mat wetland, they showed relatively poor growth performances in terms of shoot height (< 2 m) and biomass production (<$300g/m^2$) compared with those in soil-based wetlands because of oligotrophic water condition. The competitiveness and distribution of P. australis and Z. latifolia seemed to be determined by water level difference by micro-topography rather than water chemistry. Conclusion: P. australis and endangered plant species mainly occurred in the area of relatively shallow water, whereas Z. latifolia and deep-water species such as Scirpus fluviatilis mostly inhabit in the area of deep water on the floating mat. Continuously maintained water level and oligotrophic water condition in the floating mat appeared to be important environments for endangered species such as I. laevigata and M. trifoliata.

The Korean freshwater crayfish, Cambaroides similis, has recently suffered from range reduction and habitat degradation caused by environmental changes and water pollution. For the conservation and restoration of this species, it is necessary to understand the current population structures of Korean C. similis using estimation of their genetic variation. In this study, eight micro satellite loci were developed and characterized from 49 individuals collected from four locations: one population from Mt. Bukhan (BH) and three populations from Mt. Gwanak (GA) in Seoul, Korea. As a result, the number of alleles per locus ranged from 2 to 12. The observed heterozygosities and expected heterozygosities ranged from 0.000 to 0.833 and from 0.125 to 0.943, respectively, and the former values were significantly lower than the latter ones expected under the Hardy-Weinberg equilibrium. No significant linkage disequilibrium was revealed between any of the locus pairs after Bonferroni correction. From the pairwise Fst results over all samples, higher differentiation between GA-BH population pairs (mean 0.1789) was observed than between GA population pairs (mean 0.0454). This was also supported by Mantel's test showing that the genetic distances of these crayfish populations were significantly correlated with geographic distances. This result may show the regional differentiation caused by restricted gene flow between northern (BH) and southern (GA) populations within Seoul. These micro satellite markers have the potential for use in analyses of the genetic diversity and population structure of C. similis species, with implications for its conservation and management plans.
