본 논문은 SMDL (Sogang Machine Description Language)을 이용한 DSP 프로세서용 인스트럭션 셋 시뮬레이터 자동 생성기 시스템의 설계에 관해 기술한다. SMDL은 DSP 어플리케이션에 최적화된 아키텍처를 포함한 임베디드 코어의 효율적 기술을 위한 머신 기술 언어로서, 구현된 인스트럭션 셋 시뮬레이터 자동 생성 시스템은 타겟 ASIP의 SMDL 기술을 입력으로 하여 인스트럭션들의 파이프라인 스테이지 별 행위 정보를 분석한 후 cycle-accurate 인스트럭션 셋 시뮬레이터를 C++ 파일로 자동 생성한다. 구현된 자동 생성 시스템의 검증을 위해 ARM9E-S, ADSP-TS20x와 TMS320C2x 아키텍처들을 SMDL로 기술하여 시뮬레이터들을 자동 생성하였으며, 생성된 시뮬레이터들을 이용하여 $4{\times}4$ 매트릭스 곱셈, 16비트 IIR 필터, 32비트 곱셈, 그리고 FFT에 연산에 대한 시뮬레이션을 수행하였다. 결과 생성된 시뮬레이터의 정확한 동작을 확인하였다. This paper describes the system which automatically generates instruction-set simulators cores using the SMDL. SMDL describes structure and instruction-set information of a target DSP machine. Analyzing behavioral information of each pipeline stage of all instructions on a target ASIPS, the proposed system automatically generates a cycle-accurate instruction set simulator in C++ for a target processor. The proposed system has been tested by generating instruction-set simulators for ARM9E-S, ADSP-TS20x, and TMS320C2x architectures. Experiments were performed by checking the functions of the $4{\times}4$ matrix multiplication, 16-bit IIR filter, 32-bit multiplication, and the FFT using the generated simulators. Experimental results show the functional accuracy of the generated simulators.

The purpose of this study is to suggest a basis for exterior space improving in university campus in terms of upgrading the quality of university education environment by analysing user's cognition and physical feature about campus exterior space. For this, this study was survey six major university students in Busan city about perception of campus exterior space, and analyzes the user's cognition by using natural-language vocabulary analysis for qualitative approach. Next, this study analyzes the physical feature of campus exterior space by investigating user's intensive using spaces and preferred, non-preferred spaces in their universities, then propose the improved direction of campus exterior space by comparing the analyzed data of user's cognition and physical feature. A SPSS20 program is used for the data analysis and the sample sizes are 171 college students.

The chlorination kinetics of synthetic rutile prepared by selective chlorination of ilmenite with Cl<sub>2</sub> and CO gas mixture were studied in a fluidized bed. Th e effects of reaction temperature, reaction time, and the ratio of Cl<sub>2</sub> and CO partial pressure ($p_{Cl_2}/p_{CO}$) on the conversion rate of TiCl<sub>4</sub> were investigated. The conversion rate of TiC<sub>4</sub> was low under the high $p_{Cl_2}/p_{CO}$ conditions. Moreover, it was considered that the partial pressure of CO gas was more effective than that of Cl<sub>2</sub> gas when comparing the stoichiometric conversion rate and experimental results of high CO partial pressure. Considering the porous structure of particles, the rate controlling step of the chlorination of synthetic rutile was determined to be chemical reaction and the activation energy was calculated as 53.77 kJ/mol.

Object : In this study, the effect of herbal external therapy, aromatherapy, herb medication against atopic dermatitis was investigated. Method : Atopic dermatitis grade and the effect of medication was determined using Kunz type and SCORAD index. Atopic dermatitos lesion was checked by taking pictures Result : The patient's admission SCORAD index was 74.2 but during 32 days admission treatment the patients's symptoms are getting reduced. At last when she discharged, the SCORAD index was 16.1. Conclusion : In this study, herbal external therapy, aromatherapy and herb medication were shown to treat atopic dermatitis effectively by decreasing itching, oozing, crust, dryness, lichenification. It is very possible that external therapy can offer a valuable mode of the treatment of not only atopic dermatitis but also another eczema.
곡면 서까래 가공 가능성 판정을 위한 원목과 서까래 CAD 모델의 매칭

Various types of rafters are used in Korean traditional house and timber is processed to make them. Since the shape of the timber is not regular, it is needed to scan the shape of the timber using a laser scanner and compare it with that of CAD model, and finally check if it is possible to be processed. In order to do it, the CAD model should be placed at right position inside of the scanned data of the timber. The center line and bounding volume of both timber and the CAD model are extracted. Then, using bounding volume information the CAD model is placed at the right position and using center line information the orientation of the CAD model is found. The processibilty is finally checked by calculating the volume to be removed.

본 연구는 지역 총소득과 지방재정지출 간의 상호관계에 대한 분석이다. 지방재정지출과 지역경제성장에 대한 관계를 분석하기 위해 케인지안 이론과 바그너 법칙 두 가지 가설을 설정하였다. 지출이 성장을 견인한다는 전통적인 케인지안 승수이론과 지출은 단지 성장의 결과라는 바그너 법칙 중 우리나라 경제에 더 적합한 것이 무엇인지 규명하는 것을 목적으로 연구를 시작하였다. 분석기간은 1989년부터 2013년까지이고 총 25개년도이며 분석지역은 15개 특별·광역시 및 도지역이다. 패널 VAR(Vector Autoregressive) 모형과 GMM으로 분석한 결과, 우리나라는 지역총생산이 지방재정지출에 더 많은 영향을 주며 이를 통해 바그너 법칙을 입증하였다. This paper investigates the correlation between Gross Regional Domestic Product(GRDP) and Local government expenditure(LGE). LGE has dramatically increased and I intend to analyze economic effect of local government expenditure after the local autonomy system in 1991. So I set two hypothesis - one is the Keynesian theorem that LGE affects GRDP and another is the Wagner`s law that GRDP affects LGE - so that I look into better fitted economical model in case of Korea throughout 15 provinces & cities for 25 years (1989-2013). I used panel VAR because two variables have no cointegration in Westerlund panel cointegration test. As a result of this empirical study, it shows that the Wagner`s law is suitable for Korean regional economy.

The purpose of this study is to find the control strategies for ventilation and energy reduction with appropriate maintenance of indoor contaminant levels. According to a survey in other research, many mechanical ventilation systems are not often operated by residents, because residents tend to avoid powering their ventilation system in order to save utility cost. There isn’t anything to inform sufficiently how to operating ventilation system for IAQ(Indoor Air Quality). And then, without any sufficient ventilation control strategies, it would be very difficult to improve IAQ by an occupant’s manual control. If the ventilation unit is operating for 24 hour, the energy consumption would be dramatically increased. Therefore, the sensor based DCV control method is necessary for comfort and energy saving . It has been simulated both of CO₂ and TVOC sensors based DCV system for operating mechanical ventilation system. As a result of analysis, CO₂-DCV is not sufficient to maintain for comfort IAQ against TVOC from building materials and furnitures. Because CO₂ is generated irregularly by occupant’s schedules in individual room, but TVOC is emitted steadily from the finishing materials Therefore, CO₂-DCV couldn’t control the chemical contaminants like TVOC as below as the guideline. We must consider whether chemical contaminants are a proper target for control in an apartment house or not, because TVOC are more dangerous than CO₂.

시각장애인들이 생활에서 가장 불편하게 느끼는 것은 이동할 때 일 것이다. 일반적으로 시각장애인들이 인도를 걸을 땐 보통 점자유도블럭을 보조기기를 통해 인도의 방향 등의 정보를 얻게 된다. 시각 장애인들이 보조기기로 사용하고 있는 것으로 흰지팡이나 맹도견을 들을 수가 있는데, 흰지팡이는 그 기능이 너무 제한적이고 맹도견은 훈련시키는데 많은 비용이 드는 문제점이 있어 이를 대체할 수 있는 시스템개발이 필요한 실정이다. 따라서, 본 논문에서는 인도에 설치 된 점자유도블럭의 위치를 YCrCb, Canny Edge, Hough Transform 등을 이용한 검출결과를 HRTF를 이용한 방향감 있는 소리를 재생함으로서 시각장애인이 인도의 위치 및 방향을 정확히 알 수 있는데 목표를 둔다.
