The recent interest in historic protection of rural landscape concentrates on the cultural landscape. Historic rural landscape properties in the United States America have protected in the national historic preservation system as National Register of Historic Places to contribute to the enhancement of the national identity and economy. This Paper focuses on research of the National Register of historic rural landscape and applicability to Korea. The work reviews published research report, related regulations and related Bulletins. Some works were conducted by online research including a review of related webpage. The Historic Rural Landscapes in U.S.A are identified and evaluated as historically significant districts, sites, structure, objects, and buildings according to the National Resister Criteria. Those were managed as National Register of Historic Places and National Historic Landmarks in National Resister. Government provides national preservation system and tax incentive for historic preservation of rural historic Landscapes.

This paper described the design of register part, ROM and entire digital filter implementation by merging with ALU, control part last year. The register part consists of shift register, parallel load serial output register, multiplexer and selector, and we designed specially the 1024 memory cells ROM and decoder to decode the register data. Also, presented scaling algorithm to prevent the overflow.

In this paper, we introduce a technique for delayed deallocation of temporary register allocation. We achieve faster binary translation that is used in the context of register allocation. By delaying deallocation of the temporary register containing the value, it is preserved until the next instruction fetched. If subsequent instruction does not require the value again, binary translator deallocate and release the temporary register at the first stage of the next instruction.

In general, the strength assessment for heavy lift vessel is carried out under two stages. The first stage is to comply with the requirement of KR (Korean Register of Shipping) Steel Barges and Rules for Classification of Steel Ships. At the second stage, the structural strength analysis by Finite Element Method is peformed. This paper describes the strength assessment considering various loads for the heavy lift vessel of sheerleg type.

We have fabricated a single flux quantum 4-stage shift register with interface-controlled $Y_1$$Ba_2$$Cu_3$$O_{7-x}$(YBCO) Josephson junction. The YBCO Josephson junctions showed RSJ-like current-voltage(I-V) curves at temperatures 45~80K. We tested load and shift operation of shift register with binary data sequences “1000”, “1010”, “1011”, and “1111” at 58K. For all the binary data sequences, the shift register operated successfully. By operating the circuit with proper current pulses, we observed no errors during at least 12 hours operation for all the data sequences.s.

Land contamination has emerged as a major environmental and land management issue over the last decade. Although the importance of contaminated land management was continuously increased and many developed countries tried to make advanced contaminated land register system, current Korea soil regulations and policies have not been considered yet. This study analyzed existing or developing contaminated land register system from various countries to suggest implications of environmental decision support. Through this study, the introduction of contaminated land management system as creating a new system in Korea needs to considerable review to the following in order to achieve the objective through a effective adoption and operation (1) we need to establish contaminated land register system by providing a proper legal basis before the imposition of data collection, investigation, and management, (2) sufficient examination is required to identify scope of information disclosure and criteria, contents, and subjects of items from contaminated land register system.

Nowadays since the automobile is regarded as the third living space, comfortable conditions are required in the passenger compartment. The customer's concern on air-conditioning/heating, ventilation and demisting/defrosting performances has been much increased. Both ventilation and demisting /defrosting performances are directly influenced by register location, shape of regist guide vane, ventilation flow rate, air distribution , and air circulation pattern. Diffuse plume of air from the register is desirable not only to maintain comfort when the comfort when the comfortable condition has been satisfied but to improve demisting /defrosting performance. In this study, experimental and numerical investigation about the flow field of six different register vane types were carried out , respectively. The numerical analysis, based upon the $textsc{k}$-$\varepsilon$ turbulence model , was applied to the air flow field. The results show that the shape of register guide vane should be considered as an important design paramter.

The pitch range of the human voice is variable, extending from chest register to falsetto. Although numerous studies have investigated after laryngeal mechanism description of registers, systematic and objective studies were lack. The purpose of this study was to analyze and compare head register with chest register of singers acoustically. Fifteen healthy tenor major students were selected. Fifteen healthy untrained adults were the control group for this study. Long term average(LTA) power spectrum using the Fast Fourier transform(FFT) algorithm and Linear predictive coding (LPC) filter response were made during /a/ sustained in both head(G4, 392Hz) md chest registers (C3, 131Hz). Statistical analysis was performed using Mann-Whitney test. In the LTA power spectrum, head register of singer has increased level(energy gain) in the frequency band of 2.2-3.4kHz(p<0.01), and 7.5-8.4kHz(p<0.01, p<0.05). Chest register of singer has increased level in the frequency band of 2.2-3.1kHz(p<0.01), 7.8-8.4kHz(p<0.05) and around 9.6kHz(p<0.01). LTA power spectrum reveals a peak of acoustic energy around 2500Hz known as the singer's formant and another peak of acoustic energy around 8000Hz in singer's voice.

The offshore structures exposed to harsh corrosive such as the marine environment is essential for the quality management technique throughout the life cycle of initial design, construction and operation. Also, it should satisfy the design life and ensure the safety of the substructure with optimization of design process. This study focused on optimization of design condition for corrosion protection of wind turbine structure and computational analyzing was performed to evaluate the performance of corrosion protection with utilizing practical experimental data. We expect this analytical study contribute to improve the corrosion maintenance stability and economical efficiency of designing wind turbine structures. As a result, the design of cathodic protection system using sacrificial anodes required accurate identification of current density in order to meet the long term design life, which can be seen that a change of structure surface's coating breakdown factor is one of the key influencing factors.
