The purpose of this paper is to examine and analyse the features of plan type and space composition of the Siheyuan(courtyard house) which is one of the most remarkable types of the traditional dwellings in China. With the passage of time this house developed into one of the chinese house style. The technique of Siheyuan's spatial composition goes so far back in the New Stone Age. The relics of this are the colony layout, the system of four sides, the layout type of a palace, the picture of lacquered ware, the pictured brick, the earthenware of house type, the cave painting, the paintings of painters and others. The fundamental spatial conception of it arranges one or more courtyards to compose, sometimes in a very complex way, a general walled compound. The main longitudinal axis is mainly north-south, but the chief buildings, or halls are always placed transversely to it. These rectangular buildings mayor may not connect, by means of open galleries variously planned, with rows of smaller buildings flanking the courtyards on both sides. On this system, enlargement is never carried out by adding to height, but by continual duplication of existing units, and growth in breadth or preferably depth. The need for family security is thought to have led to the development of this rectangular houses with walls mainly blank on the outside, defensible entrances, and public service facilities in the center of the houses.

The female leadership styles in the 21st century have been established as a major axis. Especially, the fashion of female politicians being exposed to the public during political activities has become a main element of a measure displaying visually female leadership styles in the 21st century and image making as well. Consequently, this study conducted qualitative research through the interview method to figure out regular voters' thoughts in depth about images being required for female political leaders and the fashion maximizing those images, and drew the detailed design elements. Suggesting the clothes design reflecting those elements for female political leaders by 3D virtual clothing works emerging as a new market creating profits related to fashion. The images which female political leaders have to have and were extracted through the interviews in this study, showed as feminine, strong leader, honest, and intelligent images, and also it was shown that female political leaders displaying proper images depending on the circumstances and using those images in politics rather than sticking to a fashion identity were favored by interviewees. The present study intends to contribute to being used as basic data of various research and fashion items of virtual reality and establishment of successful fashion strategy for female political leaders.

We developed a path algorithm for ultrafast/wide area laser processing. Demands for high precision laser processing with a wide area has been increasing for a number of applications such as in solar cell battery, display parts, electronic component and automobile industry. Expansion of the area in which laser processing is an important factor to handle the ultrafast/wide area processing, it will require a processing path. Processing path is path of 2- axis stage and stage of change in velocity can be smooth as possible. In this paper, we proposed a smoothingnurbs method of improved speed profile. This method creates soft path from edge part, it is main purpose that scan area ($50mm{\times}50mm$) inside processing path makes path of topology of possible straight line. We developed a simulation tool using Visual C++.

A two-month-old female Yorkshire terrier was referred to the Veterinary Teaching Hospital, College of Veterinary Medicine, Kyungpook national University. The patient was presented with a history of dyspnea, cough, exercise intolerance and abdominal distension, but she was appetence. In physical examination the puppy was coughed on slight tracheal compression. Rectal temperature, pulse and respiratory rate were normal, and grade 3/6 systolic murmur heard at the left heart base. The murmur was crescendo-decrescendo. Electrocardiography showed sinus arrhythmia, right-ventricular hypertrophy pattern, and right axis deviation. Thoracic radiography revealed cardiomegaly, bulging of the main pulmonary artery, and enlarged left side heart. Abdominal radiography revealed abdkominal distention. Echocardiography showed hypertrophy of right ventricle and turbulence in the pulmonary artery in parasternal oblique view. Subvalvular pulmonic stenosis was diagnosis based upon the clinical signs, physical examination, electrocardiography, radiography and echocardiography. We treated the patient with furosemide, enalapril and $\beta$-blocker. After the clinical signs of cough, abdominal distension and dyspnea were disappeared, she was on just $\beta$-blocker for prevention of occurrence of congestive heart failure. Now she was recovered her health, and she is not on any medication.

Adrenal insufficiency is caused by adrenal failure or impairment of the hypothalamic-pituitary-adrenal axis. The main symptoms of adrenal insufficiency are chronic fatigue, nausea, vomiting, anorexia, and weight loss. We report a case of adrenal insufficiency in a 38-year-old female. The patient complained of headache, dizziness, anorexia, and general weakness. We treated her with Iggisaengjin-tang and acupuncture. After treatment, the patient's symptoms were improved and serum cortisol levels rose to a normal range without the aid of steroid supplementation therapy. This case suggests that Korean medicine can be effective in the treatment of adrenal insufficiency, but more clinical reports are needed.

Magnetic disturbance is one of the main factors that deteriorate the accuracy of orientation estimation methods based on inertial/magnetic sensor signals. This paper proposes a parallel Kalman filter(KF) that explicitly detects magnetic disturbances and thus can accurately estimate 3D orientation in magnetically disturbed environments. Due to the parallel nature of the proposed KF, even severe magnetic disturbances only affect yaw estimation, while roll and pitch values remain accurate. Consequently, the proposed KF can be effectively used in various applications that involve magnetically inhomogeneous environments, such as robots, ships, and planes.

The main problem of image projection on a transmission type holographic screen is color sepa-ration. And it can be overcome by using a long narrow slit type diffuser as a source of the object beam when we record the screen. But that screen is not optimized and so needs changing several conditions. To set up the system many complicate things should be taken into accounted so it is very important to analyze the basic structure by simple concepts and calculations. We designed the system so that recording and projection axis coincide in one line and showed that the analysis of the system is very simple. We did it by a 1st order paraxial approximation calculation and it was good enough to describe the system. The photo-emulsion layer shrinks after processing of the hologram. It induced unsatisfactory color matching at the viewing zone. To overcome this effect, we pre-checked the shrinkage rate of an emulsion layer by experiments and modified the recording set up to compensate for the amount of shrinkage.

X-band antenna has been widely used to effectively transmit the high resolution image data from the observation satellite to the ground station. To achieve above mission, X-band antenna is mainly composed of the 2-axis gimbal system using stepping motors and gears. However, the micro-vibration induced by the stepping motor actuation and the imperfect gear teeth alignment during this on-orbit operation is the main source of image quality degradation. In this paper, X-band antenna combined with a blade gear for micro-vibration isolation was suggested and investigated. The structural safety of the blade gear with low rotational stiffness was confirmed by structure analysis based on the derived torque budget. The isolation performance of the X-band antenna with the blade gear was verified through micro-vibration measurement test using the dedicated micro-vibration measurement device proposed in this study.

The purpose of this study is to establish the control method of the global bending distortion caused by fabrication process of hatch-cover in a container ship. In order to do it, the transitional behavior of global bending distortion in the deck of hatch-cover during fabrication process was measured by 3-dimensional measuring instrument. From the results, the principal factor controlling the global bending distortion was identified as the bending moment associated with the longitudinal shrinkage force and transverse shrinkage caused by welding and flame heating and the change of the centroid axis of hatch-cover in each fabrication process. Therefore, in this study, with the predictive equations of the longitudinal shrinkage force and transverse shrinkage caused by welding and flame heating and the simplified thermo elastic method, the predictive method for the global bending distortion was established and verified by comparing with the measured result. Based on the results, the amount of reverse bending distortion of main stiffeners was determined to prevent the global bending distortion of hatch-cover.

To fabricate low field magnetic sensors using magnetoresistance(MR) effects, we deposited thin layers of $600{\AA}$ in thickness of Ni-Co(0.7Ni-0.3Co) alloy on slide glasses. In the layers we ordered 4 arms of the fullbridge sensors in the shape of grid structure to be inclined at an angle of $45^{\circ}$ to main axis and made the areal rate increase to 67%. While the response characteristics of the fabricated sensors had good linearity in the magnetic field of ${\pm}0.5mT$ ranges, the white noise was 0.2 nV and the voltage sensitivity was 7.6 $nV/{\mu}T$.
