본 연구는 구 데이텀으로 구축된 수치지도를 지구 중심 데이텀으로의 변환에 필요한 새로운 변환 파라미터를 결정하고, 콜로케이션 방법으로부터 유도된 왜곡 모델링을 적용한 수치지도 좌표계의 변환에 관한 것이다. 국토지리정보원에서 GPS관측을 실시한 정밀 1차 기준점 190점 중에서 107점의 공통점을 파라미터 결정으로 사용하였으며, 최적 변환 파라미터의 결정을 위하여 107점을 제외한 83점의 공통점을 변환 정확도 검증에 이용하였다. 통계 분석을 통해 Molodensky-Badekas 모델로부터 산출된 파라미가 최적 파라미터로 결정되었으며, 왜곡 모델링을 수행한 결과 0.22m의 변환 정확도를 얻었다. 이는 7 파라미터만을 이용한 변환보다는 72%의 정확도가 향상된 결과를 나타내는 것이다. 또한, 1/50,000, 1/25,000과 1/5,000 수치지도의 변환 도구인 GDKtrans를 개발하였다. 이 변환 도구를 이용하여 6개 대도시 지역의 l/5,000 수치지도를 변환하고, 검사점 GPS 측량을 실시하여 변환정확도를 검사한 결과 약 1.9 m의 변환 정확도를 보였으나, l/5,000 수치지도의 위치 정보와 형상이 실제 위치 및 형상과 크게 일치하지 않고 있어 전면적으로 l/5,000의 수치지도를 재 제작하는 것이 타당하다고 판단된다.

In this paper, we present a model-driven approach for RTOS-based embedded software development and an automated tool that produces RTOS-specific code or RTOS-independent code. We define generic RTOS APIs (Application Programming Interface) that are not bound to any specific RTOS but provide most of typical RTOS services. Generic RTOS APIs can be used to describe application's RTOS-related behavior, The proposed API translator translates task code between C-code for specific RTOS and intermediate code using generic API. Also, the result can be extended to other RTOS's modifying XML transformation rule.

Transformation of housing space is the most accurate physical trail to understand main needs from residents. The scope of the study targeted the 7 si & gun districts in Gyeongsangnam-do, this study is designed to consider the characteristics of space transformation in rural apartment houses and provide basic materials for the development of rural apartment houses. The results of the study are as follow. First, such spaces as corridor and stairway are transformed into storages and outside the houses are installed tap water facility, bicycle storage. and toilet. Second, in autumn seasons when crops and grains are harvested, parking lot and rooftop are used as the space drying such agricultural products. Third, space transformation within the houses has been different depending on family type and main businesses in terms of function and time to seek efficiency and stability of residence. Fourth, rural residents concentrate on a simple change of space usage and replacement of ageing or dilapidated equipment and facilities rather than space transformation incurring more financial burden.

To demonstrate the importance of transformation efficiency in independent event, molecular and cytogenetic analysis were conducted with genomic DNA and chromosome of transgenic plants produced by Agrobacterium tumefeciens LBA4404 (pSBM-PPGN: gusA and bar). Selection ratios of putative transgenic calli were similar in independent experiments, however, transformation efficiencies were critically influenced by the type of regeneration media. MSRK5SS-Pr regeneration mediun, which contains 5 mgL$^{-1}$ kinetin, 2% (w/v) sucrose in combination with 3% (w/v) sorbitol, and 500 mgL$^{-1}$ proline, was efficient to produce transgenic plant of rice from putative transgenic callus in the presence of L-phosphinotricin (PPT). With MSRK5SS-Pr medium, transformation efficincies of Nagdongbyeo were significantly enhanced from 3.7% to 6.3% in independent callus lines arid from 7.3% to 19.7% in plants produced, respectively. Stable integration and expression of bar gene were confirmed by basta herbicide assay, PCR amplification and Southern blotting of bar gene, and fluorescence in situ hybridization (FISH) analysis using pSBM-PPGN as a probe. In Southern blot analysis, diverse band patterns were observed in total 44 transgenic plants regenerated from 20 independent PPT resistant calli showing from one to five copies of T-DNA segments, however, the transformants obtained from one callus line showed the same copy numbers with the same fractionized band patterns.

Yeast Dekkera/Brettanomyces bruxellensis is probably the most common contaminant in wineries and ethanol production processes. The considerable economic losses caused by this yeast, but also its ability to produce and tolerate high ethanol concentrations, make it an attractive subject for research with potential for industrial applications. Unfortunately, efforts to understand the biology of D. bruxellensis and facilitate its broader use in industry are hampered by the lack of adequate procedures for delivery of exogenous DNA into this organism. Here we describe the development of transformation protocols (spheroplast transformation, LiAc/PEG method, and electroporation) and report the first genetic transformation of yeast D. bruxellensis. A linear heterologous DNA fragment carrying the kanMX4 sequence was used for transformation, which allowed transformants to be selected on plates containing geneticin. We found the spheroplast transformation method using 1M sorbitol as osmotic stabilizer to be inappropriate because sorbitol strikingly decreases the plating efficiency of both D. bruxellensis spheroplast and intact cells. However, we managed to modify the LiAc/PEG transformation method and electroporation to accommodate D. bruxellensis transformation, achieving efficiencies of 0.6-16 and 10-20 transformants/${\mu}g$ DNA, respectively. The stability of the transformants ranged from 93.6% to 100%. All putative transformants were analyzed by Southern blot using the kanMX4 sequence as a hybridization probe, which confirmed that the transforming DNA fragment had integrated into the genome. The results of the molecular analysis were consistent with the expected illegitimate integration of a heterologous transforming fragment.

Development of herbicide resistant transgenic legume plants through Agrobacterium-mediated transformation has been worked in many previous studied. Plant regeneration after infection is the important step to obtain successful transgenic plants. Many attempts try to find the optimum media condition for plant regeneration after infection. However, the transformation efficiency of legume plants is still low. In this study, regeneration of some Korean legume species including two soybean cultivars (Dawon and Pungsan) and pea have been done with organogenesis which is used various kind of explants such as cotyledonary-nodes in soybean and bud-containing tissue in pea. We developed the optimum media condition for plant regeneration regulators under Agrobacterium-mediated transformation using different kind and various concentration of plant growth. As the results, B5 medium containing 2 mg/L of 6-benzylaminopurine was selected in this study for the optimum plant regeneration media. The segments were inoculated with Agrobacterium suspension harbored an IG2 vector containing bar gene which confers resistance to phosphinotricin (PPT) in 3, 5 and 7 days. The transformation efficiency was achieved in Dawon 3.03 % and pea 1.46 % with co-cultivation period of 7 days which is showed a high number of GUS positive expression period.

This study aims to analyze the digital performance of Kazakhstan through dynamic analysis of national statistics and international indices as Global Innovation Index and ICT Development Index. The research combines three stages: analysis of digital transformation policies performance, review of ICT industry development, and comparative analysis of the positions of Kazakhstan, Turkey and South Korea as a benchmark in the international indices. This research findings show that despite great efforts of Kazakhstan in digitalization, the ICT industry contribution does not increase, it even falls. The international indices demonstrate that the reason is the weakness of the country in skills, venture capital, and innovation linkages. This leads to low knowledge, technology outputs, and creative outputs. The enablers of digital and overall innovation advancement of economy are identified. According to the international rankings the country has been doing its best in Access and Use areas. Another enablers are good business environment, ease of starting a business, protecting minority investors, and FDI inflows. The findings help to draw recommendations for strategic directions in order to improve the digital performance in Kazakhstan. The main limitation of this study is a lack of dynamic information on positions of Kazakhstan in other international indices related to digitalization.
