The purpose of this study was development of a synthetic scale to measure young adults' views of life and death. Participants were 610 university students. The authors developed a View of Life and Death Scale including several subscales of afterlife views(belief in afterlife and retribution, belief in souls' effects and transmigration), meanings of death(liberation, nature, integration, collapse, impact, futility), death anxiety, death concern(death acceptance, death awareness) and life respect will(suicide inhibition, abortion inhibition, organ donation intention). The present study contributed to enhance our understanding of view of life and death in young adulthood. This study, therefore, could work as a stepping stone to investigate the structural relationship among elements included in views of life and death in young adulthood and to explore the consequences and determinants of personal view of life and death.

In this paper, we propose a model based moving object tracking algorithm in dynamic scene. To adapt the shape change of the moving object, the Hausdorff distance is applied as the measurement of similarity between model and image. To reduce the processing time, 2-D logarithmic search method is applied for locate the position of moving object. Experiments on a running motorcycle, the result showed that the mean square error of real position and tracking result is 1.845 and consequently, matching process is relatively simple and reduced.

This paper presents an algorithm of a single chip acoustic speech enhancement for telematics device. The algorithm consists of two stages, i.e. noise reduction and echo cancellation. An adaptive filter based on cross spectral estimation is used to cancel echo. The external background noise is eliminated and the clear speech is estimated by using MMSE log-spectral magnitude estimation. To be suitable for use in consumer electronics, we also design a low cost, high speed and flexible hardware architecture. The performance of the proposed speech enhancement algorithms were measured both by the signal-to-noise ratio(SNR) and recognition accuracy of an automatic speech recognition(ASR) and yields better results compared with the conventional methods.

To describe the background, mechanism, clinical results and complications of prolotheapy based on the literature review. Prolotherapy is a minimally invasive injection-based treatment of chronic musculoskeletal pain, including ligament and joint laxity. The mechanism of this injection-based technique is to initiate a local inflammatory response with resultant tissue healing. The used proliferants are classified by bio-mechanism to act in three different ways as osmotic, irritants, and chemotatics. The most commonly used proliferant is hyperosmolar (10~25%) dextrose to act by osmotic rupture of cells. High resolution ultrasound imaging of musculoskeletal structure provide a more accurate diagnosis. Also ultrasound-guided intervention provides a more high efficacy and low rate of complications. The most common complication is local pain at the injected site, that is self-limited and good responsive to anti-inflammatory agents. Other complications are rare. It is reported that prolotherapy appears safe when performed by an experienced clinician. Prolotherapy has grown in popularity and has received significant recent attention. However there are limited evidence-based data supporting the indication and efficacy of prolotherapy in the treatment of chronic musculoskeletal pain or soft tissue injuries. Future studies are necessary to determine whether prolotherapy can play an independent and definitive role in a treatment for chronic musculoskeletal pain.

Recently demand for the 3D modeling technology to reconstruct real world is getting increasing. However, existing geospatial data are mainly based on the 2D space. In addition, most of the geospatial data provide geometric information only. In consequence, there are limits in various applications to utilize information from those data and to reconstruct the real world in 3D space. Therefore, it is required to develop efficient 3D mapping methodology and data for- mat to establish geospatial database. Especially digital elevation model(DEM) is one of the essential geospatial data, however, DEM provides only spatially distributed 3D coordinates of the natural and artificial surfaces. Moreover, most of DEMs are generated without considering terrain properties such as surface roughness, terrain type, spatial resolution, feature and so on. This paper suggests adaptive and flexible geospatial data format that has possibility to include various information such as terrain characteristics, multiple resolutions, interpolation methods, break line information, model keypoints, and other physical property. The study area was categorized into mountainous area, gently rolling area, and flat area by taking the terrain characteristics into account with respect to terrain roughness. Different resolutions and interpolation methods were applied to each area. Finally, a 3D digital map derived from aerial photographs was integrated with the geospatial data and visualized.

본 논문의 목적은 대순의 '제생의세'와 도교의 '제인도세(濟人度世)', '신국동치(身國同治)' 사상과의 연관성을 살펴보고, 그것의 현대적 의의를 밝히는데 있다. 특히 대순의 '제생의세' 사상은 중국 명나라시기 도사인 민일득(閔一得)이 저술한 『고서은루장서(古書隱樓藏書)』에 나오는 '즉신의세' 사상과 많은 유사점이 발견된다. 대순진리회 역시 도교와 마찬가지로 몸과 나라를 같이 다스리는 사상을 통해 내단 수련법을 제시하였으며, 내법(內法)을 외적으로 사용하는 방법을 통하여 제생의세의 목적을 달성하고자 하였다. 삼대목적을 실현하는 요결(要訣)을 보면, 그것은 곧 천지와 심신의 조화와 안정을 이루는 것이라는 것을 알 수 있다. 즉 대순사상은 도교의 '신국동치' 철학을 바탕으로 하고 있다. 또한 대순진리회와 민일득의 '신국동치' 사상의 이론적 배경에는 유불도 '삼교병용(三敎倂用)', '삼교동수(三敎同修)' 사상이 깃들어 있음을 볼 수 있다. 대순의 '제생의세' 사상과 도교의 '즉신의세' 사상은 모두 현실사회에서 자신의 몸을 잘 다스리는 것을 통하여 세상을 이롭게 한다는 교리를 담고 있다. 양자 모두 사회의 병폐를 충분히 인식한 후, 인간과 인간, 인간과 자연, 인간의 내면과 외면의 관계개선을 통하여 인간과 세상을 다스리려 하였다. 이러한 그들의 인간과 자연에 대한 견해는 매우 큰 특색이 있으며, 시대를 초월한 사상이라 할 수 있다. 21세기 과학기술이 고도로 발달한 현대사회에서, '의세(醫世)' 사상이 나타내는 인간에 대한 관심, 사회와 생태계에 대한 윤리의식은 중요한 시대적 가치를 지닌다. 이들은 사회의 발전에 적응하면서 시대적 요구에 맞춰 탄생된 종교사상이다. 이는 사회적 폐단을 해결하고 인간과 인간, 인간과 자연, 인간의 내면과 외면의 조화를 이루고자 하는 관점을 포함하고 있으므로 중요한 현실적 가치를 지니고 있다.

Background: Funnel chest is one of the most common anomaly of chest wall, which is manifested by depression of sternum and costal cartilage. Popular operative methods were Ravitch operation and Wada operation. Material and Method: From 1983 to 1996, 21 cases of funnel chest were corrected surgically in the department of thoracic surgery, National Medical Center. Investigated age and sex distribution, combined anomaly,clinical symptom, degree of correction and complication, postoperative satisfaction. We used 2 different surgical methods, one was Wada & its variants(17 cases), the other was Ravitch and it variants(4 cases). Most of operative indications were cosmetic problems. Result: The pre-operative Welch index was 4.188, but this index decreased to 3.46 after the operations.(p=0.046) The degree of correction was higher in Wada & it variant operation than the modified Ravitch operation.(p=0.54) Their results were satisfactory in 20 patients, while unsatisfactory in 1 patient because of a k-wire fracture. There was no recurrence of chest wall depression or postoperative death during the OPD follow up period. Conclusion: We recommend Wada operation in symmetric and small degree of depressive chest wall deformity in preand post school age.

In Korea, the number of institutions providing breast MRI, as well as the number of breast MRIs, has recently increased. However, MRI-guided procedures, including biopsy and needle localization, are rarely performed compared to ultrasound-guided or stereotactic biopsy. As breast MRI has high sensitivity but limited specificity, lesions detected only on MRI require pathologic confirmation through MRI-guided biopsy or surgical excision with MRI-guided needle localization. Thus, we aimed to review MRI-guided procedures, including their indications, techniques, procedural considerations, and limitations.

Currently, most of the science and engineering students who enter the university are required to take general chemistry and general chemistry experimental subjects. However they have different learning bases about learning basic science subjects. Regarding college entrance examinations, the current system is used for selection, so they have different levels of basic knowledge. But, without considering this situation, all of the students in science and engineering are participating in the same basic science class, some learners are relatively easy to adapt to learning, while others experience extreme difficulties and suddenly give up. This is true. The purpose of this study is to develop a scale to measure the ability to learn general chemistry of freshmen in science and engineering at H University in the Seoul Metropolitan area and to analyze what kind of learning backgrounds are related to learners. The results show that gender and major are not related to general chemistry learning major, and it we found that there is a close relationship to the relationship between their major and chemistry, the level of the chemistry learning in the high school, and the selection of chemistry in college entrance examinations. In addition, it was found that the degree of feeling that pre-learning is beneficial to current learning and that it is common with current learning is also a factor related to general chemistry learning aptitude. Therefore, in this study, we propose two ways of presenting and promoting a guide for learning by majors, and establishing a step-by-step learning system considering the level of students.

This paper proposed the content-based retrieval system as a method for performing image retrieval through the effective feature extraction of the object of significant meaning based on the characteristics of man's visual system. To allow the object region of interest to be primarily detected, the region, being comparatively large size, greatly different from the background color and located in the middle of the image, was judged as the major object with a meaning. To get the original features of the image, the cumulative sum of tile declination difference vector the segment of the object contour had and the signature of the bipartite object were extracted and used in the form of being applied to the rotation of the object and the change of the size after partition of the total length of the object contour of the image into the normalized segment. Starting with this form feature, it was possible to make a retrieval robust to any change in translation, rotation and scaling by combining information on the texture sample, color and eccentricity and measuring the degree of similarity. It responded less sensitively to the phenomenon of distortion of the object feature due to the partial change or damage of the region. Also, the method of imposing a different weight of similarity on the image feature based on the relationship of complexity between measured objects using the fractal dimension by the Boxing-Counting Dimension minimized the wrong retrieval and showed more efficient retrieval rate.
