시선물관리와 단지설계 등 소규모지역에 대한 항공사진의 필요성은 날로 증가되고 있지만 촬영시 소용되는 비용과 여러 가지 제약으로 인하여 일반 항공사진 촬영용 항공기에 의한 항공사진을 얻는 데는 많은 어려움이 따른다. 본 연구에서는 대축척 공중사진의 효율적인 획득방법의 하나로서 비측량용 카메라를 장착한 원격조종 모형비행기에 의한 사진촬영에 대하여 고찰하였다. RC모형기의 원리를 조사 연구하여 공중사진촬영에 적합합 RC모형기를 제작하였고 이를 이용하여 공중사진을 촬영하는 실험을 수행하였다.실험결과 지상시설물의 공중사진을 중복촬용할 수 있었고 모형기를 이용하여서도 일반 항공사진 촬영용 항공기의 기능을 일부 대신할 수 있음을 확인하였다.

In this paper, we examined the effects of emotional and individual variables on flow in the usage of mobile application. We selected four relevant emotional and individual factors such as positive affect, negative affect, addiction and habituation. We also attempted to figure out the moderating role of communication in the effect of positive affect, negative affect, and addiction on the flow. For empirical analysis, we surveyed real users of mobile application and applied PLS (Partial Least Square) methodology for SEM (Structural Equation Modeling). As a result, we found that positive affect, addiction, and habituation have significant and positive impact on the flow. Furthermore, we also found that the moderating effects of communication on the relationships between positive/negative affect and communication are significant. Our findings provide important theoretical grounds for the effects of human behavior and emotion on the flow of mobile applications. Lastly, we also suggest significant managerial implications for the development mobile applications industry.

Human-centered computing (HCC) as a field was defined several years ago. Since then, the Web has grown significantly, and so has its impact in society at every level, creating the grounds for a new Web science. In this paper, we examine the definitions of HCC and Web science, and discuss how they might be related. On the one hand, HCC can be viewed as a set of methodologies, and on the other hand, Web science can be viewed as a platform or repository, from which behavioral data can be drawn. We examine the relationship between the two, and summarize three different research approaches that in many ways show this intersection.

Soil-cement, a hardened mixture of Portland cement, soil, and water that contain sufficient durability, has been widely utilised in Seoul urban construction sites to retain lateral earth pressures or reinforce grounds. However, little information has been reported about the strength characteristics of soil-cement constructed in Seoul urban area. In this study, we performed a number of unconfined test to the soil-cements mixed from soils sampled in 3 sites in Seoul urban area. Results indicate that unconfined strengths and optimum cement amounts of soil-cements are highly dependent on the proportion of coarse-grain particles of mixed soils. Furthermore, changes of unconfined strengths with curing time are diverse with respect to mixing conditions.

Recently, flash memories are one of best media to support portable computer's storages in mobile computing environment. The features of non-volatility, low power consumption, and fast access time for read operations are sufficient grounds to support flash memory as major database storage components of portable computers. However, we need to improve traditional Indexing scheme such as B-Tree due to the relatively slow characteristics of flash operation as compared to RAM memory. In order to achieve this goal, we devise a new indexing scheme called F-Tree. F-Tree improves tree operation performance by compressing pointers and keys in tree nodes and rewriting the nodes without a slow erase operation in node insert/delete processes.

Many applications in the areas of agricultural, hydrological and environmental resource management require data over very large areas and with a high imaging frequency - monitoring crop growth, water stress, seasonal wetland flooding and natural vegetation development. This precludes the use of fine resolution data (Landsat, Spot) on the grounds of cost, accessibility and low imaging frequency. Meteorological satellites have the potential to fill this need, given their very wide spatial coverage, and high repeat imaging. The Remote Sensing Unit (RSU) at the Zambia Meteorological Department routinely receives, processes and archives imagery from both Meteosat and NOAA AVHRR satellites. Here I wish to present some examples of applications of these data sets that arise from the RSU work - relationships between rainfall and vegetation development as assessed by satellite, derived information and seasonal patterns of flooding in the Barotse floodplain and the Kafue flats. I also wish to outline ways in which a more widespread use of this data by the Zambian institutions canbe achieved.

The 4th National Comprehensive Planning is a blueprint of national plan to be accomplished by the year 2020. This article indicates grounds of establishing the plan, characteristics and problems of the plan. Following is the principal contents which are treated in the article; 1st, strategy of constructing opened and combined land axis, 2nd, competency intensifying strategy by areas, 3rd, constructing health and pleasant national environment,4th, strategy for organizing express transportation and information network through the whole land, 5か, special features related building basis of cooperation interchange between North and South Korea. In the conclusion, although there were some problems through 3 times national comprehensive planning, this plan should be helpful to develop nation keeping balance for which construction and preservation would be harmonized appropriately.

개인정보의 수집과 사용이 지속적으로 증가하고 있는 추세에서, 개인정보를 보호하기 위한 법적 근거가 마련되고 각종 정책과 제도가 시행되고 있지만, 개인정보보호에 관한 교육과 그 효과에 대한 분석이 부족한 상황이다. 이에 본 연구에서는 대학생들의 개인정보보호에 인식정도와 실제 인지수준에 대해 분석하고, 개인정보보호 교육의 만족도를 조사하였다. 분석결과에서 학생들의 개인정보보호에 대한 관심이나 개인정보 노출 염려는 매우 높은 편이었으나, 실제 개인정보보호를 위한 노력이나 개인정보보호를 위한 권리 및 제도에 대한 인지수준은 매우 낮은 것으로 분석되었다. 또한 정보보호 교육을 받은 경험 및 만족도도 매우 낮은 것으로 조사되었다. 학생들은 개인정보보호 교육의 필요성은 크게 공감하였고, 일회성 교육보다는 정기적이고 지속적인 교육을 선호하는 것으로 분석되었다.

The northeastern Pacific and eastern Bering Sea supports large and divers finfish and shellfish compelxes. The North Pacific fishing grounds are largest fish production total 30.89 percent of the world in 1983. Recent action by the around countries extending their fisheies jurisdiction to 200 mile has provided a new environment. The new approch to fisheries management has resulted in an arormous expansion in tile demand for scientific information. These are no longer limited to biological concerns. Emphasis has been focused recently on the need to understand the economic, social, politics and philosophy characteristics of a fishing and how they will be affected by management decisions. The horizontal management and portfolio management for fisheries has increased interest in complex biological models and the coupling of these models with economic, politics and phyisophy components. Successful completion of this task will require and expanded understanding of oceanographic, biological, economic, social, politics and philosophic process associated with fisheries. Particular attention should be devoted to acquiring information an data processing for Korean trawl fishery, stock assessment in the areas. The need for international collaboration in management must be stressed. Some northeast Pacific and eastern Bering Sea fish stock migrate over long distances and political boundaries. Further, nearly all the fish stocks are harvested by several nations. The features require cooperation and coordination of research activities. The horizontal management will be made a way these activities for the around countries in the sea. Strongly, tile proposed again, Pacific International Council for Exploration of the Seas, PICES will interest between all users of the area's fisheries.

이 연구는 국가균형발전과 지방분권이라는 시대적 조류에 편승하여 현재의 '완전 집중형' 국가도서관시스템을 '집중-분산형'으로 재편하기 위한 이론적 배경과 논리적 근거를 제시하는데 그 목적이 있다. 이를 위하여 주요 문화선진국인 영국, 독일, 프랑스, 일본을 벤치마킹의 대상으로 삼아 각각의 분산형 국가도서관시스템 구성을 정밀 분석하였다. 이를 바탕으로 후속연구에서는 국가도서관 지역분관 건립을 위한 중장기 기본계획(기본모형, 운영체계 및 역할분담 모형, 자료보존센터 모형 등)을 제시할 것이다.
