SW education has been incorporated into the regular curriculum since the 2015 curriculum due to the social changes caused by the 4th industrial revolution. The most important thing in SW education is the improvement of Computational Thinking. The study on the underprivileged who have little opportunity for education was relatively inadequate. In this study, CT competency of 135 underprivileged students were measured who were suffering from educational underprivileged. The underprivileged students were recruited from 15 local children's centers in Namyangju city and recruited 210 general students from B elementary schools in Namyangju city by setting up a selection criterion. As a result of comparing the CT competence between the two groups, it was found that the CT competence of the underprivileged students was lower than that of the general students, and suggested several implications with this result.

The increase of human activities has been extensively changed the breeding habitats of birds directly or indirectly, where the reproductive success of the birds has been seriously reduced. Leisure activities on water, such as fishing, influenced the breeding biology of waterfowls. However, few researches have been done for this in Korea. We examined the effects of fishing activity on nest selection and density of four waterfowl species at Namyang Lake: Coot (Fulica atra), Moorhen (Gallinula chloropus), Little Grebe (Podiceps ruficollis), and Great Crested Grebe (Podiceps cristatus). We divided the Namyang Lake into three study areas. Except for the number of anglers, there were no significant differences among the three study areas in the kinds of avian predators, the water depth around study areas measured for possible territorial predatory mammals' passing over, and the values of Relative Importance Percentage of occupying plants. The results showed that waterfowls bred in Namyang Lake preferred the areas with few anglers for the nests. From this study, we recommend that leisure activities including fishing should be prohibited or restricted during the breeding periods of waterfowls for the stable breeding success and that further systematic researches and managements for the species are necessary.

전 세계적으로 수소연료전지에 대한 관심이 집중되고 있다. 이미 미국, 일본, 캐나다 등 선진국에서는 수송용, 가정 상업용, 휴대용 등 다양한 용도의 연료전지 기술개발 및 보급에 나서고 있다. 우리나라는 아직 연구개발 및 실증단계에 머물러 있다. 정부는 2012년까지 연료전지 자동차 3,200대, 가정용 1만기, 상업용 2,000기, 분산전원용 300기를 보급하다는 목표로 연료전지 보급을 추진하고 있다. 연료전지 전문가들은 이러한 보급을 통해 급속한 가격인하가 예상돼 경쟁력 있는 기술과 상품으로 거듭날 것으로 전망하고 있다. 특히 동양건설산업이 세계 최초로 경기도 남양주에 연료전지 공동주택을 2010년 준공할 예정이어서 건설업계의 연료전지 주택 보급 활성화의 계기가 될 것으로 예상된다. 연료전지 자동차의 경우 수소충전소가 필요하다. 이러한 점에서 중장기적으로 수소충전소 설비 건설 분야가 설비건설업계의 새로운 시장이 될 가능성을 기대해볼 수 있다. 이번 호에서는 연료전지 기술 및 동향, 시공사례를 살펴본다.

대규모 연안개발은 연안지형의 변화와 함께 다양한 식물상의 변화를 만드는 원인이 되고 있다. 때문에 시화방조제， 새만금방조제， 남양만 방조제 등의 대규모 방조제 공사 이후에 연안갯벌에서 나타나는 식물상의 변화를 관측하는 것은 연안습지환경의 변화를 분석하는 중요한 척도가 된다. 본 연구에서는 아리랑 2호 의 고해상도 자료를 바탕으로 연안습지의 지형변화에 따라 나타나는 생물상의 식생지수를 분석하고 이들의 시-공간적변화가 연안지형의 특성과 공간규모의 대칭적 특성을 나타내고 있음을 제시하였다. 특히，중급해상도에 의해 분석되었던 식생지수를 고해상도 위성관측 자료와 현장조사 자료를 비교하여 이를 검증하였다.

우리나라는 산업화 이후 많은 인공 저수지를 건설하였으며, 이후 부영양화 등의 수질 악화로 하천 및 호소의 오염은 심각한 상황에 놓여있다. 이에 대해 점오염원에 대한 대책을 마련하였지만, 하천 및 호소의 오염저감에 한계를 드러내었으며 그 원인을 비점오염원에서 오염물질이 대량으로 하천 및 호소에 유입되기 때문인 것으로 추정하고 있다. 이에 본 연구에서는 화성호의 주요 유입하천(남양천, 자안천, 어은천) 유역의 오염원 조사와 유입하천의 강우시기별 수질 및 유량조사를 통하여 오염부하량의 산정 및 유입하천의 오염부하량 유달율을 산정함으로써, 비점오염원에 대한 보다 명확한 대책 마련을 위한 기초 자료로 활용하고자 하였다. 강우시 수질 및 유량조사 결과, 유입하천의 유량은 강우 사상과 매우 큰 관계를 지니며, 강우 강도 및 강우 지속 시간 등의 변화에도 많은 유출 특성의 변화가 일어나는 것으로 조사되었다. 월별 유달율 산정 결과 홍수기에 가장 높았으며, 이는 강우의 집중으로 인한 비점오염물질에 의한 영향으로 판단된다. 강우시의 유달율이 높게 나타난 것은 강우시에는 점 및 비점오염원 모두에서 비점오염 형태로의 유출 가능성이 커 이에 대한 집중적인 관리가 필요할 것으로 판단되며, 유달율 산정으로 하천 수계 특성에 적합한 소유역의 유달율 적용을 통해 점 및 비점오염원에 대한 효율적인 관리를 위한 자료로 이용함으로써 하천 및 수계 관리를 위해 보다 실효성 있는 관리 방안을 마련할 수 있을 것이다.

The geophysical survey at pre-investigation stage can hardly provide the detailed information on geological structure of site which has difficulty in access and thick overburden. The TSP (VSP applied in tunnel) survey at post-investigation stage can show the detailed geology ahead of tunnel and around cavern. The TSP survey was carried out at the Pyongtaek LPG storage cavern site during the cavern excavation and provided the location and orientation of the fault inferred below Namyangho. In order to confirm the result of TSP survey four boreholes were drilled in access tunnel. The fault was also detected by borehole survey and the location was coincided with the result of TSP survey. Depend on the result of TSP survey and core logging, the design such as cavern layout and length could have been changed. As another case history the TSP survey was performed at the Mumeuje road tunnel which has poor geological information due to thick overburden. The support design was also changed on the base of TSP survey.

This study aims to evaluate the efficiency in the provision of employment services for the middle-aged by using spatial analysis in GIS. Based on location information of employment service institutions, we find service areas of the institutions and calculate regional rates of duplication and exclusion in terms of spatial coverage of the employment services. Taking into account potential demand for employment services, the regions with high priority in the provision of the services are identified. Among the regions, those with high exclusion rate of the services are designated as the regions of insufficient service level. Results indicate that Namyangju-si is a representative region of insufficient employment service level. To improve efficiency in the provision of employment services, we suggest to relocate employment service institutions that have been located in a region of high duplication rate such as Siheung-si, Danwon-gu, Gangnam-gu, Songpa-gu into the locality of Namyangju-si.

This study is the result of a design proposal to create a history and culture complex for the "Gungjip," an Important Folklore Cultural Heritage, and its surroundings located in Namyangju, Gyeonggi Province. In particular, the purpose is to introduce a new design approach to a historical and cultural complex consisting of the Gungjip House and Hanok annexes to be opened to the public in the future; and to provide its implications for future study. Although the architectural condition of Gungjip House is well preserved, several problems have been found in the use of the site as a public space due to the lack of a plan for systematic space experience, lack of specific spatial programs, and the too much shade due to uncontrolled green areas, etc. Therefore, the plan presented in this study largely sought to respect the meaning of historical landscape as a public space and to balance with the contemporary needs. The design strategies derived through basic research are to strengthen the sense of place as a cultural heritage; to respect the ecological characteristics of the site and visual harmony with the surrounding environment; and to suggest spatial programs suitable for the contemporary needs. Based on these strategies, the framework for the entire space is conceptually composed of four spaces; Oewon, Ganjeong, Jujeong, and Huwon, and proposes systematical land use and landscape experience. The main feature of this plan is the landscape approach, which aims to preserve the architectural cultural assets in their original form, but to create a reasonable land use and meaningful landscape experience based on the sense of place.

In order to evaluate the change of aquatic environment in the reclaimed Hwaong Reservoir, situated in the early stage after construction, this study was conducted to measure the change of precipitation, temperature, and salinity from June 2002 to January 2006. The range and mean of temperature was $-0.7{\sim}33.4^{\circ}C$ and $13.6^{\circ}C$, respectively. Temperature of upstream part rapidly changed during the transitional period; from spring to summer and from fall to winter. It showed abrupt decrease with high discharge from the streams temporarily. While, hypolimnetic temperature of upstream happened to be somewhat higher than that of surface or downstream. The range and mean of salinity was 0.3${\sim}$32.3 psu and 25.3 psu, respectively. Vertical difference of salinity was marked, and the change in the surface water was much higher than middle or bottom layers. It showed the marked difference at all stations, except for the bottom layer of upstream into which Namyang Stream flows, indicating that vertical gradient of salinity is strongly sustained in the reservoir. Salinity was changed markedly during the storm period (June${\sim}$October), and freshwater with low salinity was expanded from upstream to downstream along the surface layer. The surface of the reservoir was totally covered by the stream discharged water with a large amount of silt and low salinity during this period. The difference of temperature and salinity between the surface and bottom layer ranged $-10.6{\sim}9.7^{\circ}C$ and $-27.1{\sim}30.0$ psu, respectively. The big difference of salinity appeared with a large discharge of freshwater from the streams or large input of seawater through the gate. Salinity was negatively correlated with temperature, indicating the influence of monsoon storm events on the salinity under the whole watershed scale of this brackish reclaimed reservoir.
