  • The so-called “Quick Game”-models resemble a central element within the Compound Gaming approach of military systems analysis proposed by Huber [1, 2]. This paper introduces such an analytical model designed to investigate the battle-effectiveness of alternative army structures. The nature of its results is discussed from numerical experiments covering the (German) Army Structure 4, Loser's Area Coverage Defence Concept, and Afheldt's Area Defence Concept. It turns out that Loser's concept promises to have a comparatively high potential to stabilize the early conventional forward defence, hence being an interesting alternative for further analysis in depth.

  • The IMS (Infrared or Intermediate-wide, Medium-deep Survey) program for the search of z~7 quasars has been running since last year. In order to discover enough number of quasars at z~7, a strategy sufficing both survey area (~150 square deg.) and image depth (23 AB mag in J filter), together with using existing multi-wavelength data is chosen. We have been carrying imaging observations with the UKIRT 4m telescope, now covering ~50 square deg. (including UKIDSS survey area) of J-band data. We then used selection in color-color space to choose high-z quasar candidates having the rest-frame Ly-alpha break, and to exclude contamination from stars and galaxies at low-z. We show quasar candidates of redshift z~7 and z~6, out of 25 square deg. data analyzed, and note implications and future plans.

  • The present paper consists of 42 taxa belonging to 7 genera of desmids (green algae) collected from two districts of Garhwal region of Uttarakhand (Western Himalayas). The district Haridwar is located 29° 55’to 29° 59’N latitude and 68° 5’to 68° 30’E longitude covering about 2360 km2 area and Dehradun district is situated between 77° 34’to 78° 18’E longitude and 29° 58’to 30° 58’N latitude. Seven genera of desmids are (with number of taxa in parenthesis): Closterium Nitzsch. (9), Cosmarium Corda ex Ralfs (25), Euastrum Ehr. (2), Spondylosium Breb. (1), Micrasterias Ag. (1), Staurastrum Meyen (3), Arthrodesmus Ehr. (1). All these taxa constitute new records for the area. The algal localities are relatively cleaner than those of majority of urban areas. A rich assemblage of desmids shows that water bodies of these hilly areas are still undisturbed and need protection for preservation of algal biodiversity.

  • Recently, there has been a rapid increase of interest in u-Health systems or instruments. The importance of testbeds has been discussed deeply also. However, beyond laboratory or ward environments, testbeds covering metropolitan area cannot be found easily. Moreover, there has been few papers which discuss the results of testbed operations for various instruments in different age groups. In this paper, the results of testbed which operated in Daegu metropolitan area are discussed and improvement directions to strengthen the competitiveness are proposed using user analysis. In particular, the results of trial services using the u-Life support instruments (medication reminder, falling safety phone, bio-patch and shirts, etc) for super aging societies in the near future are discussed.

  • For 262 locations throughout the southern part of Korean peninsula, intensities of 13 December 1996 Yeongweol earthquake are estimated to make an isoseismal map and investigate attenuation properties in the southern part of Korea. Due to the inherent uncertainties in the estimation of intensities, obtained intensity map show quite scattered pattern of intensity distribution. Estimated intensities range from III to possibly Ⅷ. In case of intensity larger than Ⅵ, considerable damages such as fracturing of walls are reported one of the most significant feature of the intensity map is, considering its magnitude 4.7 reported by KMA, the felt area is appeared to be unusually large covering most of the Korean peninsula except Cheju island. This result indicates ether the magnitude is underestimated or the focus of this earthquake is much deeper. Assuming shallow(less than 10km) intraplate earthquake, we obtained average magnitude 5.6 by using the area encircled by isoseismal contour lines from intensity IV to intensity Ⅶ. This ambiguity can be clarified if more reliable focal depth is estimated by using teleseismic earthquake records in the future.

  • Galaxy clusters, the largest gravitationally bound system, are important means to place constraints on cosmological model and to study the evolution and the formation of galaxies and their large scale distribution. We will report results from our study of galaxy clusters in the European Large Area ISO Survey North1/North2(ELAIS-N1/N2) fields, covering a total of 10.8 $deg^2$. We combine multiple wavelength data from IMS survey, UKIRT Infrared Deep Survey-Deep Extragalactic Survey (UKIDSS-DXS, JK bands), Spitzer Wise-area InfraRed Extragalactic survey (SWIRE, Optical-Infrared bands), and CFHT (u,g,r,i,z bands.) The photometric redshifts are derived from these datasets and are used to search for high redshift galaxy clusters at 0.8 < z < 1.5.

  • The purpose of this study is to evaluate the potential application of TERRA-ASTER data in Thailand. ASTER VNIR, SWIR and TIR data covering greater Bangkok and Chiangmai province were processed with various techniques in the spatial domain to study the applicability to various disciplines. ASTER data was also combined with other satellite data in order to utilize multi-sensor methods. It was found that VNIR data can clearly identify urban pattern including road network and vegetation index. While SWIR and TIR data can well separate between urban and non urban area and TIR data can differentiate among thermal surfaces. Furthermore, dense urban areas such as central business area could be highlighted. Land utilization, vegetable distribution and differences of temperature distribution were investigated.

  • About 117 weed species composed of 44 annuals, 26 biennials, and 47 perennials belonging to 36 families were identified from golf fields in both Anyang an Taegu country clubs on May and September, 1989. Graminae was the most widely occuring family covering 21 species, followed by 14 species in compositae, 8 species in leguminosae, polygonaceae and caryophyllaceae respectively, and 5 species in cyperacae etc. The highest numbers of weed species occured in the rough area in golf fields, followed by tee, fairway and green area in orders. The dominant weed species in golf fields based on importance value and frequency were Digitaria Sanguinalis, Poaannua, Polygonum aviculare, Trifohum repens, Plan tago asiatica, Capsella bursa-pastoris Rumx acetocella and Kyllinga brevifolia.

  • 최근 들어와 위성을 이용한 항법시스템인 GPS의 중요성이 점점 더 부각되고 있다. 미국을 위시로 유럽 등 각 대륙마다 자기들에 맞는 광역 보정위성항법 시스템을 구축하고 있다. 이에 우리나라도 우리나라에 맞는 광역보정위성항법을 구축해야 할 시점으로 보여지고 있는 시점이다. 기존의 보정위성항법이 반경 100km 정도를 포괄하여 넓은 영역에 서비스를 하기 위해서는 많은 수의 기지국이 필요한데 반해 광역보정위성항법은 적은 수의 기지국으로 넓은 영역을 포괄할 수 있는 장점을 지니고 있다. 이에 본 논문에서는 한국에 맞는 광역보정위성항법 구축을 위해서 모의 실험을 통해 한국을 포괄하는 광역보정위성 항법의 유효성을 검증하고 사용된 알고리즘에 대해 설명한다.

  • Purpose: This study was conducted to define the experiences of nursing activities in Gwangju area during the May 18 (5 18) Democratic Uprising over 30 years ago. Methods: Data were collected in 2010 and 2011 through individual in-depth interviews. Ten nurses who worked in general hospitals in the Gwangju area during the 5 18 Democratic Uprising were interviewed using open-ended questions. Each interview lasted about 2~3 hours. Verbatim transcripts were analyzed using Van Kaam's method of phenomenological analysis. Results: Four categories emerged from the analysis: anxiety about the incident which was experienced for the first time; progress of the 5 18 events and relationship to participants; changes in nursing environment; retrospection and wishes related to the 5 18 incident. Conclusion: This oral history study revealed more clearly of the experiences of nursing activities in the Gwangju area during the 5 18 Democratic Uprising. The data may provide a basis for writing history nursing in the community, and can be a basis for guidelines covering nursing care in crisis.
