To determine the movement patterns, home range, and use of structural features of captive-bred one- or two-year-old Amur ratsnake (Elaphe schrenckii) juveniles in the natural habitat, we radio-tracked a total of 11 juvenile snakes in a mountain valley in Chiaksan National Park, South Korea, between August 21 and September 20, 2010 and between June 13 and July 13, 2011. During the first week of the release, most juveniles moved short distances, daily, but they increased their distances after the first week. The body weight of the juveniles was negatively related with the movement rate (dividing the number of movements by the number of relocations), which was positively related with the mean daily distances moved and the size of both a kernel 50% and 95% home range. During the study period, the juveniles moved daily, approximately 17 m, and the size of the minimum convex polygon and the 50% and 95% kernel home ranges were 1.8 ha, 0.4 ha, and 3.0 ha, respectively. The released captive-bred juveniles were more frequently confirmed underground or on the ground rather than on rocks or on trees. Our results suggest that the body condition of released individuals, the seasonal time of the release, and the existence of available prey and shelters in the habitat should be carefully considered when releasing captive-bred Amur ratsnake juveniles for the rehabilitation of field populations.

19세기 후반 이후 온실가스의 과도한 배출로 인하여 지구의 연평균 기온이 상승하여 폭우, 폭설과 같은 이상기후 현상이 전 세계적으로 빈번하게 증가하고 있다. 또한 고도의 경제성장으로 인구가 밀집되어 있는 도시지역에서는 화재, 테러 등의 사고가 발생할 경우 심각한 재산 및 인명피해가 발생할 수 있다. 본 연구에서는 이와 같은 재난재해에 의하여 발생하는 이재민들을 보호할 수 있는 대피시설이 필요하며 이들을 보호할 수 있는 적정 수용면적을 제안하고자 한다. 우리나라 국민안전처에서 1인당 수용면적을 $3.3m^2$으로 지정하였지만 그 기준의 설정 근거에 대해서는 명시되어 있지 않다. 따라서 국민안전처에서 명시된 1인당 수용면적 $3.3m^2$의 적합성을 고려하고 그 후에 다양한 기준정립을 감안하여 1인당 적정 수용면적에 대해 제시하고자 한다.

본 연구는 폭력가정에서 여성과 자녀 모두 심각한 수준의 위기를 경험하고 있다고 전제하고 그들의 생존과 대처와 관련된 갈등과 딜레마를 모-자녀관계의 관계적 경험을 이해하고자 현상학적 조사를 수행하였다. 쉼터에 거주하고 자녀양육경험이 있는 10명의 여성들을 대상으로 심층면담을 수행하였으며 질적분석 소프트웨어인 아틀라스티를 활용하여 자료 분석의 효율성을 극대화하였다. 가정폭력은 언제든지 아동학대로 전이, 통합될 가능성이 매우 높은 사건으로 매맞는 여성과 자녀는 '모성과 효성의 위기'를 공유하며 대처노력에 있어 서로를 위한 생존 에너지를 동원할 수 있는 상호적 존재의미를 갖는다. 폭력가정의 여성과 자녀들을 위한 사회복지적 개입은 피해가족구성원들의 복합적 현실을 심도 깊게 이해함을 전제로 여성과 아동을 동시에 역량강화 시키는 통합적 접근이어야 한다.

As the number of children's libraries has increased in Korea, it has been discussed to improve the quality of design in the libraries. In a reading room of children's library, spatial consideration should be focused on the children under 10 years old since they are in important points to learn Hangul and to develop reading habits. This study is aimed to examine the characteristics of a floor-sitting reading room, where children can feel like a home, stay in clean and safe and play while reading. The seven case studies of floor-sitting reading rooms are analyzed from the viewpoint of each factor of physical environment, including structure, furniture, and decoration. The following is the summary of findings of this study. First, floor-sitting reading rooms tend to compose main reading areas around bookshelves. Reading areas create the characters by changing floor levels and arranging furniture associated with windows, columns, and wall-type bookshelves. In the reading areas, movable low-level tables are frequently placed for flexible space uses, and seats for reading tend to put together with fixed bookshelves. Second, the central areas of the reading rooms are often shaped in the forms of pods, storytelling areas, sculptures, and unique furniture. Especially storytelling areas and pods play the cores of the reading rooms with the varying steps of floors and pictorial graphics on walls. Third, decoration elements in the reading rooms are designed with graphics, visual displays, and sculptural decorations. In my case studies, spatial elements such as reading nooks, attics, tunnels, and shelters are not often found in the floor-sitting reading rooms even though children like to have them. Since it is the advantage of floor-sitting reading rooms where children can take off shoes and act freely, we should look for the design of such spatial elements in the floor-sitting reading rooms.

Various kinds of leaf spots and blights were found in kiwifruit (Actinidia deliciosa) orchards on 2006 in Korea. Disease incidences were quite variable between open-field and rain-proof shelter. Rate of diseased leaves was recorded as about 70% at open-field orchards in late season but use of rain-proof vinyl shelters alleviated the disease incidences by 20%. Angular leaf spots appeared at early infection stage on June and several other symptoms were also recognized as the disease developed afterward. On September, brown leaf blights were the most frequent, followed by grayish brown ring spots, silvering gray leaf blights, zonate leaf blights, dark brown ring spots and angular leaf spots at open-field orchards. Four fungal species were frequently isolated from the disease symptoms. Phomopsis sp. was the most predominant fungus associated with the leaf spot and blight symptoms on kiwifruit, followed by Glomerella cingulata, Alternaria alternata and Pestalo-tiopsis sp. Phomopsis sp. was commonly isolated from angular leaf spots, silvering gray leaf blights, and zonate brown leaf blights. G. cingulata, A. alternata and Pestalotiopsis sp. were isolated from grayish brown ring spots (anthracnose), brown ring spots and zonate dark brown leaf blights. Typical symptoms appeared on the wounded and unwounded leaves, which were inoculated by each of Phomopsis sp., G. cingulata, and Pestalotiopsis sp., but A. alternata caused symptoms only on the wounded leaves.

The purpose of this study is to develop a method to spread out the ecological ponds in urban areas more effectively. It is urgent to supply the ecological ponds in more broad scope to ensure the water space in urban areas which has been dried out. It is necessary to formulate a plan for improving the amenity in the cities through creation a biotop in swampy land by building rainfall ponds. Thus, a model of the ecological pond in this study has been developed by reviewing the related researches which provide the theoretical basis and by considering the characteristics of nature for a naturally approached pond. This study has produced a ecological pond model in order to introduce and spread out damp biotop. Ecological aspects have been mainly considered in designing and building the pond model. This model consists of areas for emerged plants and bog plants and has its advantage in providing animals and insects with habitats and shelters. In addition, the model includes areas for emerged plants, which are very effective in purification of the rainfall from the rooftop. After the construction of the pond, the plants were planted according to the plan, and the infiltration trench was installed beside the pond to drain out the overflow of the pond. The result of this research has shown the possibility of supplying the ecological pond in small parks and in schools of the city in an easy way. Through the application of this pond system, the water cycle and the ecosystem in urban areas will be improved.

최근 선박건조기술이 발전했음에도 불구하고 교통량의 증가와 해양레저의 활성화로 사고위험은 더욱 증가하고 있다. 이 논문에서는 그동안 발생했던 해양사고를 분석하여 사고발생을 최소화할 수 있는 여러 가지 방안과 사고발생시 신속하고 구조할 수 있는 체계적인 구조시스템에 대하여 논의한다. 선박이 해상에서 안전하게 항행하기 위해서는 선박기술, 항해관련 장비, 우수한 인적자원, 교통관제 등과 같은 구성요소들이 제도적으로는 구축되어야 하고, 각각의 항행요소들이 유기적으로 작동되어야 한다. 또한 사고발생시 사고수습이 신속하게 진행될 수 있도록 체계적으로 정부조직이 구성되어야 하고 그 조직들이 긴밀한 협력관계를 유지해야 한다. 민간부분에서의 협력지원도 현재보다 더욱 강화되어 국가의 관리영역에서 벗어난 해역에서는 민간부분에서 구조할 수 있도록 민간 구조대가 활성화되어야 한다.

Tornadoes are vertical swirling air formed because of the existence of layers of air with contrasting features of temperature, wind flow, moisture, and density. Tornadoes induce completely different wind forces than a straight-line (SL) wind. A suitably designed building for an SL wind may fail when exposed to a tornado-wind of the same wind speed. It is necessary to design buildings that are more resistant to tornadoes. In tornado-damaged areas, dome buildings seem to have less damage. As a dome structure is naturally wind resistant, domes have been used in back yards, as single family homes, as in-law quarters, man caves, game rooms, storm shelters, etc. However, little attention has been paid to the tornadic wind interactions with dome buildings. In this work, the tornado forces on a dome are computed using Computational Fluid Dynamics (CFD) for tornadic and SL wind. Then, the interaction of a tornado with a dome and a prism building are compared and analyzed. This work describes the results of the tornado wind effect on dome and prism buildings. The conclusions drawn from this study are illustrated in visualizations. The tornado force coefficients on a dome building are larger than SL wind forces, about 120% more in x- and y-directions and 280% more in z-direction. The tornado maximum pressure coefficients are also higher than SL wind by 150%. The tornado force coefficients on the prism are larger than the forces on the dome, about 100% more in x- and y-directions, and about 180% more in z-direction. The tornado maximum pressure coefficients on prism also are greater those on dome by 150% more. Hence, a dome building has less tornadic load than a prism because of its aerodynamic shape.
