  • The FP-tree(Frequency Pattern Tree) mining association rules algorithm was proposed to improve mining performance by reducing DB scan overhead dramatically, and it is recognized that the performance of it is better than that of any other algorithms based on different approaches. But the FP-tree algorithm needs a few more memory because it has to store all transactions including frequent itemsets of the DB. This paper implements a FP-tree algorithm on a general purpose UNK system and compares it with the DHP(Direct Hashing and Pruning) algorithm which uses hash tree and direct hash table from the point of memory usage and execution time. The results show surprisingly that the FP-tree algorithm is poor than the DHP algorithm in some cases even if the system memory is sufficient for the FP-tree. The characteristics of the test data are as follows. The site of DB is look, the number of total items is $1K{\sim}7K$, avenrage length of transactions is $5{\sim}10$, avergage size of maximal frequent itemsets is $2{\sim}12$(these are typical attributes of data for large-scale convenience stores).

  • The osseous or osteocutaneous free fibula flap has become the gold standard for most mandibular reconstructions because of its favorable osseous characteristics. However, disadvantages, such as the time-consuming reconstructive step, difficulty in performing the osteotomies to precisely recreate the shape of the missing segment of mandible and poor bone-to-bone contact play a role in making the surgeons look for alternative flaps. With the advent of computerized design software, which accurately plans complex 3-dimensional reconstructions, has become a process that is more efficient and precise. However, the ability to transfer the computerized plan into the surgical field with stereolithographic models and guides has been a significant development in advancing reconstruction in the maxillofacial regions. The ability to "pre-plan" the case, mirror and superimpose natural structures into diseased and deformed areas, as well as the ability to reproduce these plans with good surgical precision has decreased overall operative time, and has helped facilitate functional and esthetic reconstruction. We describe a complex case treated with this technique, showing the power and elegance of computer assisted maxillofacial reconstruction from the University of Michigan, Oral and Maxillofacial Surgery.

  • Objectives: Regardless of its negative impact on quality of life, little is known about the importance of alopecia from the patients' perspective. This study aimed to explore the whole experience of chemotherapy-induced alopecia among Korean breast cancer patients including perception, attitudes, preparedness, and changes after alopecia. Methods: Patients expected to experience or had experienced alopecia were recruited at a tertiary hospital in Seoul, Korea. Semi-structured in-depth interviews were performed in 21 patients. Recurrent issues were identified and placed into thematic categories. Results: All patients think that appearance is important and they pay attention to how they look like. They had negative perceptions about alopecia. Patients were not well prepared for alopecia, and experienced substantial physical, psychological and social distress. Lack of information and limited social support combined with negative images of cancer made it difficult for patients to overcome the trauma and deterred them from usual daily activities resulting in poor quality of life. Conclusions: Patients were not well prepared for alopecia and negative perceptions, lack of preparedness, and limited social support and resources increased alopecia-related distress. Educational programs for preparing patients to cope with alopecia distress and advocate activities to change people's negative perception about alopecia are needed to reduce the burden imposed by alopecia in cancer patients.

  • Efficient space plans are built upon relations of both human and physical compositions, and the standard of the interaction is basically the human scale. Especially in medical areas, the character of the users within human scale design environment is quite significant. Unlike large hospitals with great plans and scalability performed by experts, mid-sized clinics tend to have limited space, designed by non-specialists who highlight aesthetics over functionality in floor plans which leads to poor quality in medical service. For this reason, this study will include the application of human scale based therapy rooms within the clinic from a physical standpoint and will further analyze and pinpoint any room for improvement to further enable more efficient ergonomic space planning. In this study, theoretically will contemplate over human scale, mid-sized clinic, therapies, and therapists, while the case study will include status of the recent human scale based mid-sized clinic from a physical viewpoint, classification and analysis amongst human and physical compositions chosen by discretion from either a newly opened or a newly re-modeled clinic within the last 2 years, which has 15 beds or more, minimum 3 physical therapists, with more than 5 different therapy facilities in the metropolitan area in order to measure the human scale of therapy rooms in a mid-sized clinic. As a result, the area where improvement can practically be applied is the physical composition, which does not include human scale like human composition factors as therapists and patients, and hence, I suggest the human scale applied efficient medical space plan become the base of this study and look forward to subsequent improvement in the quality of medical services.

  • This study was conducted for the first time based on the evidence that cadaver practice is not easy in the university without medical school where cadaver dissection is not easy to look for. The purpose of this study was to evaluate the effect of osteology practice at human anatomy course for students at the freshman stage in college of health science without medical school. Both self report questionnaires and evaluation paper were analyzed depending on the course of higher education and gender. As a result of analysis, most students thought that osteology practice was interesting and it helped to understand of anatomy lecture. But students from liberal arts had poor understanding of bone's direction compared with students from natural sciences. And most students wanted to do cadaver dissectionafter osteology practice. In conclusion, osteology practice was recommended to student's expectation as well as education of gross anatomy in department of biomedical laboratory science, collage of health science without medical school. This study suggested that practice of gross anatomy should run parallel with lecture.

  • In this research the current situations of libraries of 119 rural elementary schools are examined. These schools are the applicants for the 'Campaign for Libraries for Rural Schools' sponsored by Chosun Ilbo in 2009. Through the content analysis of their applications, the factors of facilities, collection, and environment are described. One the surface, most of these applicants look fine with the current size of collection and annual additions. They, however, commonly document the extremely poor conditions of facilities, unbalanced and low quality of books, lack of financial support, and cultural isolation. Even though they are not the typical rural school libraries, it seems urgent to improve their inferior conditions that any library statistics never shows in numbers. In this research, it is considered significant to make local governments and offices of education change their attitude toward rural school libraries and increase their financial support to them. The suggestions are as follows: First, let them know that school library policies concern the voters in communities; Second, use the visibility of various authoritative library assessments and awards; Third, strengthen the qualitative aspect of library evaluations.

  • In order to take a good look at effectiveness of cooling of Fog system and Pad-Fan system, we chose 49 farm households which were installed evaporative cooling system and 2 farm households which were installed Pad-Fan system and Fog system for a test. We execute the test on 29 households out of 49.6 households, which were installed Pad-Fan system, were able to use; however, 6 household out of 9 which were installed Fog system couldn't use it. The main reason was the clogged on nozzle. The cooling efficiency on Pad-Fan system was 77.4%, but it was very poor on Fog system. Since there are many problems on Fog system, we need more research on size of fog, the location of nozzle, control of Fog systems.

  • Thoracic outlet syndrome is actually a collection of syndromes brought about by abnormal compression of the neurovascular bundle by bony, ligamentous or muscular obstacles between the cervical spine and the lower border of the axilla. First of all a syndrome is defined as a group of signs and symptoms that collectively characterize or indicate a particular disease or abnormal condition. The neurovascular bundle which can suffer compression consists of the brachial plexus plus the C8 and T1 nerve roots and the subclavian artery and vein. The brachial plexus is the network of motor and sensory nerves which innervate the arm, the hand, and the region of the shoulder girdle. The vascular component of the bundle, the subclavian artery and vein transport blood to and from the arm. the hand. the shoulder girdle and the regions of the neck and head. The bony, ligamentous, and muscular obstacles all define the cervicoaxillary canal or the thoracic outlet and its course from the base of the neck to the axilla or arm pit. Look at the scheme of this region and it all becomes more easily understood. Compression occurs when the size and shape of the thoracic outlet is altered. The outlet can be altered by exercise, trauma, pregnancy, a congenital anomaly, an exostosis, postural weakness or changes. Thoracic outlet syndrome has been described as occurring in a diverse population. It is most often the result of poor or strenuous posture but can also result from trauma or constant muscle tension in the shoulder girdle. The first step to beginning any treatment begins with a trip to the doctor. Make a list of all of the symptoms which seem to be present even if the sensations are vague. Make a note of what activities and positions produce or alleviate the symptoms and the time of day when symptoms are worst. Also, note when the symptoms first appeared. This list is important and should also include any questions one may have.

  • This study aimed to analyze how a variety of relations created by the actions of characters shown in SBS Wednesday and Thursday dramas are communicated by using Greimas' actantial model. This study analyzed the sparsity structure that the subject have in relations between the subject, and a desire structure that the subject have will appear if we look into the interactive and binding relation between the subject and the object in the process of solving those problems. In the relations between the subject and originator, the role of originator in the dramas was limited when his or her character is established as a poor character weaker than the subject and the one to be protected, whereas he or she was more authoritative than the subject in the structure that originator shares a role as an antagonist. Objectors shown in three works gave help to the solution of incident after all by turning coat as another cooperators of the subject and the object, showing a tendency to reach maturity rather than being unhappy.

  • The purposes of this study were to identify the living environment in rural fishing area and to suggest checking methods for implementation performance. Rural service standard is the key factor of rural development in Korea. In 2012. The first Implementations of performance was announced. The results were presented to the unit by the City and the County. Because of Fishing villages exists as a unit by the haengjeongri. It is difficult to know the status of the fishing villages by the Rural service standard. In order to look for the actual conditions in rural fishing village it was investigated in the 100 Eochongye. The data used in the analysis is 577 questionnaires. Analysis showed that rural fishing areas were superior to general state of rural in the 8 items of rural service standard. Especially housing, transportation and health care sector in rural fishing area wes better than general state of rural. But Public safety and order is relatively poor. This is because Fishing village contains islands. Presenting to improve rural service standard based on the results of research. The items of rural service standard should be measured the actual residents' accessibility than opportunity of the public service, and after setting the rural service standard clearly related to the quality of life of residents in each sector. Accessibility aspects of the customer for the public services should be considered. Checking the performance for the unit by the City and the County should be replaced as a living zone in order to consider the facilities using nearby.
