본 연구의 목적은 국가균형발전특별법에 의거하여 추진되고 있는 국가균형발전사업과 그 재원인 국가 균형발전특별회계를 면밀히 살펴보고, 국가균형발전사업의 계획·실행·평가·환류에도 불구하고 더욱 심화되고 있는 경제와 인구의 지역간 불균형에 대한 상세한 소고를 통해 대규모 국가균형발전사업의 필요성과 추진방향을 제시하고자 한다. 수도권과 비수도권 사이의 경제와 인구의 불균형이 나날이 심해지고 있는 상황에서 이를 해결하기 위한 대규모 국가균형발전사업이 요구되고 있는 현실이다. 재정분권을 통해 국가균형발전특별회계의 상당 부분이 중앙정부에서 지방정부로 이양되는 만큼 국가균형발전프로젝트는 단순히 지역별 적정예산 안분으로 끝나서는 안되며, 국가적 차원에서 지역의 경제와 인구를 고려하여 보다 장기적이고 거시적인 관점에서 균형발전을 달성하기 위한 대규모 국가균형발전사업의 추진방향 재정립이 요구된다. The purpose of this study is to suggest the necessity and direction of large-scale national balanced development projects. To do this, look closely at the national balanced development project, which is being promoted under the National Balanced Development Special Act, and the special account for national balanced development. Then make detailed comments on the imbalance between regions of the economy and the population that is getting worse despite the planning, implementation, assessment, and feedback of the national balanced development project. As the economic and population imbalance between the metropolitan area and the non-metropolitan area is increasing day by day, a large-scale national balanced development project is needed to solve this. The current large-scale national balanced development project should not simply end with an appropriate budget division for each region, as a significant portion of the special account for national balanced development is transferred from the central government to local government through fiscal decentralization. In order to achieve balanced development in a true sense from a longer-term and macroscopic perspective at the national level, considering the regional economy and population, it is necessary to re-establish the direction of large-scale national balanced project.
Capital Goods Imports and Economic Growth - Trade Policy or Structural Capability?
Wooseok Ok 한국경제발전학회 2007 經濟發展硏究 Vol.13 No.2
Capital goods imports are an important source of technological transfer from developed countries (DCs) to less developed countries (LDCs). However, in practice, poor countries do not import more capital goods from the DCs than their rich counterparts. Based on the idea of “absorptive capability”, this paper will attempt to explain this observation by the fact that the presence of a relatively well-developed local capital goods sector helps a more efficient use of imported capital goods. An open developing economy may face a dilemma in the early stages of industrialization because local capital goods should be used with foreign capital goods as complementary inputs while at the same time their further development can be limited by the international competition. In this case, a developing economy can be caught in a poverty trap even under an open trade regime. Simple protectionist measures cannot serve as an appropriate policy alternative because, among other issues, they reduce the amount of technology spillovers from industrialized countries. The cross-country empirical evidence shows that the quantity of machinery imports from the OECD countries are more closely associated with the degree of development of local capital goods industries than with trade policies. That is, economies with a more advanced capital goods sector tend to import relatively more capital goods from industrialized economies than others.
Strengthened and flexible pile-to-pilecap connections for integral abutment bridges

Pile-to-pilecap connection performance is important as Integral abutment bridges (IABs) have no expansion joints and their flexible weak-axis oriented supporting piles take the role of the expansion joint. This connection may govern the bridge strength and the performance against various lateral loads. The intention of this study is to identify crack propagation patterns when the pile-to-pilecap connection is subjected to lateral loadings and to propose novel connections for improved performance under lateral loadings. In this study, eight different types of connections were developed and modeled, using Abaqus 6.12 to evaluate performances. Three types were developed by strengthening the connections using rebar or steel tube: (i) PennDOT specification; (ii) Spiral rebar; and (iii) HSS tube. Other types were developed by softening the connections using shape modifications: (i) cylindrical hole; (ii) reduced flange; (iii) removed flange; (iv) extended hole; and (v) slot hole connection types. The connections using the PennDOT specification, HSS tube, and cylindrical hole were shown to be ineffective in the prevention of cracks, resulting in lower structural capacities under the lateral load compared to other types. The other developed connections successfully delayed or arrested the concrete crack initiations and propagations. Among the successful connection types, the spiral rebar connection allowed a relatively larger reaction force, which can damage the superstructure of the IABs. Other softened connections performed better in terms of minimized reaction forces and crack prevention.

A 14-year-old, spayed female, poodle was presented with dysuria and hematuria. A mass that appeared hypoechoic on ultrasound and hypoattenuating on computed tomography (CT) extended from the bladder neck to the urethra. Magnetic resonance imaging (MRI) showed the mass invading the muscular layer of the bladder, urethra, and prostate with distinct margins. Transitional cell carcinoma (TCC) was confirmed with the CADET-BRAF test. This study describes the CT and MRI features of suspected TCC lesions involving the bladder, prostate, and urethra. MRI showed superior soft tissue contrast resolution, enabling evaluation of invasion of the muscular layer of the bladder and urethra.
Layout Synthesis and Loop Parameter Optimization of a Low-Jitter All-Digital Pixel Clock Generator
WooSeok Kim,Jaejin Park,Hojin Park,Deog-Kyoon Jeong IEEE 2014 IEEE journal of solid-state circuits Vol.49 No.3
<P>This paper presents a dual-loop ADPLL suitable for video pixel clock generation. The dual-loop architecture where a fast subloop works as a DCO inside a main loop is chosen since it can efficiently suppress the ring oscillator phase noise. In order to satisfy a wide tuning range and fine resolution requirements in the pixel clock PLL, the TDC and DCO with two-step and bottom-up control are employed. An s-domain model is utilized to tune the loop parameters so that the dual-loop PLL has the optimum jitter performance. The measurement results match well with the proposed s-domain model and clearly show the effectiveness of the dual loop in suppressing the phase noise of the DCO. We propose a new cell-based layout technique to avoid performance degradation during automatic placement and routing, which is compatible with the conventional digital design environment. A chip that occupies 0.032 mm<SUP>2</SUP> has been fabricated in the 28-nm CMOS technology. The synthesized DCO shows 1.7-LSB DNL which is close to a full-custom layout. The rms integrated jitter is only 15 ps at 250 MHz, even though PLL operates at the extremely low input frequency of 100 kHz. Power consumption is 3.1 mW at 250 MHz with a 1.0-V supply.</P>
