This study was carried out understand the general conditions about management of hypertension and the differences in opinions between the East- ern-Western Nursing Sciences. In this context, this study was aimed to find out a possible integration of the Eastern-Western Nursing Sciences for the management of hypertension and to suggest a distinct frame of Korean nursing intervention method which is unique for the hypertensive patients by combining two hypertensive management systems originated from the Western type, mainly classified by stage, and the Eastern type, typically classified by form as they are identified in the literature. From the research literature including both domestic and foreign, this study identified that exuberance of Yang of the Liver form mainly appeared to the patient who is at a border hypertension or the fir- st stage of hypertension, Deficiency of Yin of the Liver and Kidneys form mostly appeared to the first stage and the second stage of Hypertension and Deficiency of the both of Yin and Yang form appeared to the third stage of Hypertension. These unifications of the types of Hypertension classified by stages and forms suggest the possibility not only of integration of the Eastern-western Medicine but also of establishment for the intervention of specific nursing management which is the united Eastern-western Nursing Science for the Hypertension. Hence, the new frame for the nursing management of Hypertensive patient is suggested as follows: 1) In case of the exuberance of Yang of the Liver form, as classified by form which is categorized to the border Hypertension or the first stage of Hypertension, nursing intervention should include general therapy, cooking meal and neutral care to restrain the condition of the exuberance of Yang of the liver. 2) In case of the deficiency of Yin of the liver and the Kidneys form, as classified by form which is categorized to the second stage of Hypertension, nursing intervention should include both the general and drug therapy and their use in combi- naton with cooking meal and neural care to re- strain the condition of the deficiency of Yin of the Liver and Kidneys. 3) In case of the deficiency of both of Yin and Yang form, as classified by form which is categorized to he third stage of Hypertension should include both the general therapy and drug therapy and their use in combination with cooking meal and neural care to restrain the condition of deficiency of the both of Yin and Yang. In addition, using this basic frame of Hypertensive management, a specific way of nursing intervention, Which is suitable for exuberance of Yang of the Liver form, Deficiency of Yin of the Liver and Kidneys form, and deficiency of both of the Yin and Yang form and classified by Korean herbal medicine related to hypertension, should be pursued continuously in the future.

Recently, the development and application of unmaned robots are increasing in various fields including surveillance and reconnaissance, planet exploration and disaster relief. Unmaned robots are usually controlled from distance using radio communications but they should be equipped with autonomous travelling function to cope with unexpected terrains and obstacles. This means that unmanned robots should be able to evaluate terrain's characteristics quantitatively using mounted sensors so as to traverse harsh natural terrains autonomously. For this purpose, this paper presents an algorithm for extracting terrain information from elevation maps as an early step of traversability analysis. Slope and roughness information are extracted from a world terrain map based on least squares method and fractal theory, respectively. The effectiveness of the proposed algorithm is verified on both fractal and real terrain maps.

A computer vision technique of estimating the location of an unmanned ground vehicle is proposed. Identifying the location of the unmaned vehicle is very important task for automatic navigation of the vehicle. Conventional positioning sensors may fail to work properly in some real situations due to internal and external interferences. Given a DSM (Digital Surface Map), location of the vehicle can be estimated by the registration of the DSM and multiview range images obtained at the vehicle. Registration of the DSM and range images yields the 3D transformation from the coordinates of the range sensor to the reference coordinates of the DSM. To estimate the vehicle position, we first register a range image to the DSM coarsely and then refine the result. For coarse registration, we employ a fast random sample matching method. After the initial position is estimated and refined, all subsequent range images are registered by applying a pair-wise registration technique between range images. To reduce the accumulation error of pair-wise registration, we periodically refine the registration between range images and the DSM. Virtual environment is established to perform several experiments using a virtual vehicle. Range images are created based on the DSM by modeling a real 3D sensor. The vehicle moves along three different path while acquiring range images. Experimental results show that registration error is about under 103m in average.

Operation usually brings about psychological stress as well as physical stress to the patient and it greatly influences the maintenance of the homeostasis. Until now, most of the nursing research concerning the anxiety of the patient undergoing an operation has been done while the patient was under general anesthesia. Under local anesthesia, the anxiety of the patient who undergone operation is short. However, there is much demand of the operational nurses to mediate between the patient who is undergoing operation when fully conscious, as they are aware of the patient`s anxiety and to decrease the patient`s anxiety of this local anesthesia. Therefore, this research tries to verify the effects of the Hand-holding program on the anxiety of the operational patient undergoing local anesthesia and affirms the role of the nursing intervention. As an unequivalent control group nonsynchronized designs, this research selects out 20 control groups and 21 experimental groups at random who have received cataract operation while under local anesthesia and after implementing the Hand-holding program to the experimental groups while undergoing the operation, the effect of the experiment was observed. By observing the Epinephrine, Cortisol, blood pressure, and pulse for the physical indexes before and after the enforcement of the hand-holding, and using the measurement of Speilberger(1972) for the psychological indicators for the anxiety of the patient before and after hand-holding, the results were analyzed through SAS program. As a results, intervention of hand-holding had a remarkable effect to decrease the anxiety felt by the patient and the diastolic blood pressure also was effectively decreased. On the other hand, through the decrease of the systolic blood pressure was also observed, it was not statistically significant. In the Epinephrine and Cortisol indicators, the intervention of hand-holding was revealed to have an insignificant effect. The Hand-holding was revealed to have an indicators, the intervention of Hand-holding was revealed to have an insignificant effect. The Hand-holding program may be said to have an effect which decreases the psychological anxiety of the patient undergoing local anesthesia.

Recently, the interests in the development and application of unmaned robots are increasing in various fields including surveillance and reconnaissance, planet exploration, and disaster relief Unmaned robots are usually controlled from distance using radio communications but they should be equipped with an autonomous travelling function to cope with unexpected terrains and obstacles. This means that they should be able to evaluate terrain’s characteristics quantitatively using mounted sensors so as to traverse harsh natural terrains autonomously. For this purpose, this paper presents a method for extracting terrain information, that is, slope and roughness from elevation maps as a prior step of traversability analysis. Slope is extracted using the curve fitting based on the least squares method and roughness using three metrics and their weighted average. The effectiveness of the proposed method is verified on both a fractal map and the world model map of a real terrain.

The purpose of this study is to analyze the difference between the poor with bad credit(PBC) and the general poor(GP) in terms of the actual conditions of economic and cultual living and socio-economic consciousness, and to develop policies and consumer education programs to help the poor with bad credit(PBC). For this study we conducted the survey from Aug. to Sep. 2003, and analyzed the collected data(125 samples for PBC and 609 samples for GP) by cross-tabs analysis(χ2 test) and t-test. The major findings of this study are as follows. 1) The actual conditions of economic living showed difference between PBC and GP. Because the amount of debt of PBC were greatly more than that of GP, monthly average savings and financial assets of PBC were less than those of GP in spite of more income of PBC. The debt payment expenses of PBC were greatly more than that of GP, but their expenditures on food, health and medical care were less than that of GP. 2) The actual conditions of cultural living showed difference partly between PBC and GP. The percentage of going to movies, reading newspaper and joining internet of PBC was higher than those of GP, but the percentage of having summer vacation tour of PBC was lower than that of GP. 3) The level of socio-economic consciousness showed difference partly between PBC and GP. The tendency to suicide or crime, impulse buying of PBC showed higher than that of GP. In conclusion, we suggested the policies and consumer education programs for supporting PBC.

연쇄알구균 감염에 의한 급성 인후염 후 반응성 관절염 1예

연쇄알구균에 의한 급성 인후염 후 발생한 반응성 관절염은 급성 류마티스열의 개정된 진단기준을 충족하지 못하면서, 지속적 혹은 재발성의 비이동성 관절염과 발열, 홍반성 결절, 일시적 간기능 이상 등을 보이면서 심장염과 무도증을 드물게 동반하는 질환이다. 따라서, 발열을 동반한 급성 관절염 환자에서 감별해야 할 질환 중의 하나이며, 심근염 예방을 위한 페니실린 요법의 적응증 및 기간에 대해서는 아직 이론이 많은 상황으로, 보다 광범위한 연구가 필요하다. 저자들은 연쇄알구균에 의한 급성 인후염 1주 후에 발생한 하지의 다발성 비이동성 관절염과 함께 결절홍반 및 일시적 간기능 이상을 보인 환자에서 PSRA로 진단하고 비스테로이드성 항염증제 및 스테로이드로 성공적인 치료를 하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Poststreptococcal reactive arthritis (PSRA) is associated with recent streptococcal infections. However, PSRA is distinct from acute rheumatic fever by its clinical manifestations: non-migrating arthritis, erythema nodosum or erythema multiforme, and transient elevation of serum transaminases. We experienced a 33-year-old man who presented with fever, arthritis of both knees and ankles, and erythema nodosums on extensor surfaces of lower legs which developed 6 days after the onset of pharyngitis symptoms. Blood and urine cultures were negative. Throat culture was negative for group A β-hemolytic streptococcus. The ASO titers increased up to 2080 IU/mL in sequential monitoring. The result of bone scan was compatible to arthritis of both knees and ankles. There were no signs or symptom of carditis. He showed clinical improvement with anti-inflammatory drugs (naproxen 1,000 mg/day and prednisolone 7.5 mg/d). PSRA should be included in the differential diagnosis of patients presenting with arthritis combined with fever.
