이 논문에서는 비교적 두꺼운 결정에 대한 일련의 고 분해 영상들에 대한 IWFR 분석의 유용성을 실험하였다. 이를 위해 JEOL ARM 1300S를 이용하여 실리콘 결정의 30 nm 두께의 [01-1] 방위와 35 nm 두께의 [11-2]에 대한 일련의 비 초점 단계의 고 분해 영상들을 관찰하였다. 이로부터 두꺼운 시료에 대해서도 IWFR 분석 결과로부터 결정 밑 표면의 파동함수를 얻을 수 있음이 밝혀졌다. 그러나 강한 동역학적 산란에 의한 효과 때문에, 이 함수의 영상패턴은 시료의 원자열 구조의 패턴을 다만 정성적으로만 반영하고 있다. 그럼에도 불구하고 이 패턴은 결정구조의 중요한 단서를 제공할 것임은 의심의 여지가 없다

Repeated using carpentry workers work at working tools because of occupational low back pain, such as musculoskeletal disorders, occupational diseases are on the rise. For this purpose, through the analysis of musculoskeletal disorders and work tools and studies are underway to improve the working conditions of the workers. However, existing previous studies may not reflect the working tools used for carpentry worker dies when working at a construction site that Therefore, in this study, the work in the form of construction, one of the jobs of worker dies classified according to the working tools of musculoskeletal disorders correlated to analyze. The results of this study are as follows. working tools of a total of seven different dies used in the installation process. Musculoskeletal disorders, waist / drill such correlation was very strong. Also showed that a total of three of the tools used in the formwork dismantling cutter musculoskeletal disorders of the arm / elbow and a very strong correlation.

The Port of Pyeong Taek is located on the west coast, meaning that the difference between the rise and fall of tide is great (flood tide 1.8 to 2.9 knots, ebb tide 1.6 to 2.9 knots). Due to mainly N~NW'ly strong winds & high waves during winter, navigating as well as loading & discharging vessels must focus on cargo handling. The strong tidal and wind forces in the Port of Pyeong Taek can push an LNG carrier away from its berth, which will end up causing forced disconnection between the vessel's cargo line and shore-side loading arm. The primary consequence of this disconnection will be LNG leakage, which will lead to tremendous physical damage to the hull and shore-side equipment. In this study, the 125K LNG Moss Type ship docked at No. 1 Pier of the Pyeong Taek is observed, and the tension of the mooring line during cargo handling is calculated using a combination of wind and waves to determine effective mooring line and mooring line priority management. As a result if the wind direction is $90^{\circ}$ to the left and right of the bow, it was found that line monitoring should be performed bearing special attention to the Fore Spring Line, Fore Breast Line, and Aft Spring Line.

Purpose: The purpose of this study is to analyze the measurement differences of simple radiographs according to radiation projection angle using a phantom and to propose methods for objective analysis of simple radiographs. Materials and Methods: We took simple radiographs with different projection angles using a C-arm image intensifier and measured five parameters of the foot on the simple radiographic images. Five parameters include lateral tibiocalcaneal angle, lateral talocalcaneal angle, naviculocuboid overlap, lateral talo-first metatarsal angle, and lateral calcaneo-first metatarsal angle. Intraobserver and interobserver reliability were verified, and then intraclass correlations of parameters were analyzed. Results: Radiographic parameters of the foot showed high intraobserver and interobserver reliability. Lateral tibiocalcaneal angle has a strong negative linear relationship with rotation and a moderate negative linear relationship with tilt. Lateral talocalcaneal angle has a moderate positive linear relationship with rotation and a strong positive linear relationship with tilt. Naviculocuboid overlap has a strong positive linear relationship with rotation and a moderate positive linear relationship with tilt. Lateral talo-first metatarsal angle does not have a linear relationship with rotation and a moderate negative linear relationship with tilt. Lateral calcaneo-first metatarsal angle has a moderate positive linear relationship with rotation and tilt. Conclusion: More precise evaluation of the foot with a simple radiograph can be performed by understanding the changes of radiographic parameters according to radiation projection angle.

Finite element analysis showed that strong magnetic fields were distributed around the arc furnace where the strongest magnetic field was generated around the three phase cables, and followed by the electrodes and the mast arm in decreasing order. Magnetic field decay patterns around the arc furnace could be fitted by introducing exponential formula,$Y=Y_0+Ae^{\frac-{x}{t}}$. These results showed that magnetic field intensities around the arc furnace could be estimated at any 3-dimensional positions using the finite element method (FEM).

This paper describes the implementation of a 4 channel embedded DVR system. It receives analog video from CCD cameras and converts to 640${\times}$480 CCIR-656 digital video by 30 frames/sec. These digital images are compressed to the wevelet transformed image using hardware codec which is capable of 350:1 real-time compression and decompression. The DVR is working on linux and it implemented on an embedded system which is based on StrongARM processor. For the interface between processor system module and image processing module, GPIO and memory control module are used, device drivers are developed. Linux kernel source is customized. This paper provides techniques of embedded system development and embedded linux porting.

There is no line of demarcation between the shoulder and elbow regions. Pain In the arm may originate at the shoulder with reference downwards or less often at the elbow with reference upwards. Most pains indicated by the patient at the elbow or forearm have a local origin, since at the more distal part of the upper limb the capacity for correct localization is good. Once it is clear that the elbow region is at fault, the joint and the muscles about it are tested by ten movements. 1. Four. Passive extension, flexion, pronation, supination-full range, LOM, painful, painless. 2. Four. Resisted extension, flexion, pronation, supination-strong, weak, painful, painless. 3. Two. Resisted flexion, extension at the wrist-painful, painless. The muscles that perform theses two movements arise from the humeral epicondyles and a lesion in either often causes pain felt at the elbow although the tissuse affected is not functionally a part of the elbow (i. e. Tennis elbow and Golfer's elbow).

In this paper, a speech recognition system using a speaker defendant algorithm is implemented on the PC. Results are loaded on a LDM display system that employs Intel StrongArm SA-1110. This research has completed so that this speech recognition system may correct its shortcomings. Sometimes a former system is operated by similar speech, not a same one. To input a vocalization is processed two times to solve mentioned defects. When references are creating, variable start-point and end-point are given to make efficient references. This references and new references are changed into feature parameter, LPC and MFCC. DTW is excuted using feature parameter. This security system will give user permission under fore execution have same result.

Most Embedded Web Camera Server products currently deployed on the market adopt JPEG for compression of video data continuously acquired from the cameras. However, JPEG does not efficiently compress the continuous video stream, and is not appropriate for the Internet where the transmission bandwidth is not guaranteed. In our previous work, we presented the result of designing and implementing an embedded web camera streaming server using MPEG4 codec. But the server in our previous work did not show good performance since one CPU had to both compress and process the network transmission. In this paper, we present our efforts to improve our previous result by using dual CPUs, where DSP is employed for data compression and StrongARM is used for network processing. Better performance has been observed, but it is found that still more time is needed to optimize the performance.
