If detected early enough, cervical cantor may have a good survival rate due to its preneoplastic state. However, the process is so time consuming that a medical expert can handle only a small amount of such examinations. In this paper, we propose a new nucleus extraction algorithm for uterine cervical pap smears in order to mitigate such burdens of medical experts. In the preneoplastic state cytodiagnosis images, it is important to differentiate three main areas - background, cytoplasm and nucleus. Thus, we apply lighting compensation and $3{\times}3$ mask of B channel in order to restore damaged image and remove noises respectively. The cell object is obtained from those clean binarized images with Grossfire algorithm. When there are clusters of cells, the target nucleus can be obtained with repetitive binarization of R channel brightness. In our experiment of using uterine cervical pap smears of 400 magnifications that is common in the diagnostic cytology, our method is able to extract 40 nucleus out of 45 population successfully.

The ultimate goal of architecture is to construct a building through design and supervision. According to this circumstance, architectural education divided into two part ; design and construction. However, these two processes have to be one program for better education. In this aspect, steel housing program could be a desirable one because of its structural(bearing wall) system and relative short construction schedule. In KUT architectural program, steel housing has been one of the most effective and important for about ten years. In this research, the contents(s/w) and running process of this program and practice lab(h/w) will be introduced with detail. And this study could be a good guideline for a better combination program with theory and practice in architectural engineering field.

ECN is accurate in determining traffic congestion since it explicitly notifies the incipient congestion. Therefore, ECN method has been thoroughly studied in the field of wireless TCP. This paper introduces a formula to find the optimal threshold for ECN marking. We have implemented a Petri net model of 'TCP with ECN strategy' and performed simulations on it in order to verify the validity of the formula. We have also introduced ideas of applying the formula in practice. The primary contribution of this paper is proposing a formula to find the optimal threshold for ECN marking. However, introducing the Petri net model of 'TCP with ECN strategy' is no less valuable contribution because it can be helpfully used by the researchers in studying network protocols. We have built the Petri net model by modifying the existing Petri net model of TCP. In order to add ECN strategy to the existing model, we have mainly modified the network part. We have also modified sender part and receiver part as well.

Many scholars, clinicians and faculties of music therapy have dealt various issues on educational and clinical curricula for training music therapists. Depending on the philosophical orientations of educational institutes, the emphasis are different. The purpose of this paper is to examine and identify the areas for competency for gaining qualification in music therapy by reviewing the definitions of music therapy from the academic and professional perspectives; discipline-based, practice-based, and intrapersonal competency. The unique characteristics of music therapy as a professional discipline should be reflected in its curriculum and training content. Educational strategies need to be formulated to strengthen intrapersonal competency. The paper also discussed the consequential gains accordant with intrapersonal competency such as personal self-help skills using musical resources and coping with burnouts.

In the 60's to 70's, frame selection was a purely mechanical consideration almost entirely dominated by the optician and his subjective judgments. Toddy the cosmetic factor is predominant. The variety of frame color, materials, and style means that the main burden of selection has passed to the customer, leaving the optician control a subtle factor often difficult to exert. Common materials include nickel silver, Hi-nickel alloy, bronze, stainless steel, gold, gold plated, gold clad, copper beryllium, titanium and sometimes aluminium. In manufacturing of metal frames with the materials, even though fashion is the stimulant of consumer demand, all the metal frame for the prescription to refractive correction should be designed correctly styled eyewear which is cosmetically pleasing, functional correct, physically comfortable, mechanically and structurally perfectible, and temperamentally acceptable.

Topographic mapping from economic SPOT stereo imagery than aerial photographs has become possible. Many of authors have studied the possibility of base map revisions and the accuracy of results. They have concluded that the SPOT image is suitable for 1/50,000 to 1/100,000 topographic map. For topographic map, orthophoto and DTM generation from SPOT imagery, accurate exterior orientation parameters are needed. But since the geometric characteristic of SPOT image is dynamic linear array imagery, the conventional bundle adjustment for photogrammetry can not be directly applied. Reliability is the ability to detect gross error, which is called the internal reliability, and the effect of non-detectable gross error on the results of exterior orientation, which is called the external reliability. This paper shows how the reliability of SPOT imagery depends on the different coordinate systems, presentations of coordinate for flight direction, orders of exterior orientation parameters and distribution of control points, and thus analyses the theoretical reliability of the exterior orientation, which can provide a basis for the planning of SPOT projects.

In modern industry, the accuracy and the sulfate-finish requirements for machined parts have been becoming ever more stringent. In addition, the measurement and understanding of surface topography is rapidly attracting the attention of the physicist and chemist as well as the engineer. Optical measuring method is used in vibration measurement, crack and defect detection with the advent of opto-mechatronics, and it is expected to play an important role in surface topography. In this study, the principle of confocal microscope is described, and the advanced 3-D surface measuring system that has better performance than the traditional confocal microscope is developed. Suitable fixtures arc developed and integrated with the computer system for generating 3-D surface and form data. Software for data acquisition and analysis of various parameters in surface geometrical features has been developed.

Many researchers have studied the process of retail evolution in the United States and in Europe. Although extensively studied(e.g., Agergaard, Olsen & Allpass, 1970; Oren, 1989), used in conceptual work(e.g., Cist, 1968), and applied as foundation in empirical work(e.g., HcNair, 1958), some limitations exist as follows: inability to cover multiple types of retail institutions and limited quantification. The purpose of this study is to build a conceptual framework combining existing retail evolution theories to overcome existing limitations. Data collection and analysis followed a qualitative research design, specifically a grounded theory type of design with a constant comparative analysis method. As a result of the study, a conceptual framework was built by synthesizing aspects of retail evolution theories and showed retail institution types in a change process.

This study aims to analyze empirically the scale of region that has been covered in "The Journal of the Korean Geographical Society(대한지리학회지)" and "The Journal of the Korean Association of Regional Geographers(한국지역지리학회지)" over the last 20 years. Generally speaking, it was found that "The Journal of the Korean Geographical Society" has published a relatively more number of articles with larger scale of region and "The Journal of the Korean Association of Regional Geographers" has published more articles with smaller scale of region than the counterpart journal. Also, this study has revealed that the ratio of the studies in both journals utilizing both town/village scale(읍 면 스케일) and city/county scale(시 군 스케일) has increased continuously with marginal fluctuations. On the other hand, the ratio of the studies in both journals combining single metropolis/province scale(시 도 스케일), multiple metropolis/province scale(시 도보다 큰 스케일), and state scale(국가 스케일) has decreased continuously in general. In sum, this study is expected to offer useful data as well as future research direction to the Korean geographers.
