In this paper, we proposed fast and efficient algorithm for detecting near-duplication based on content based retrieval in large scale video database. For handling large amounts of video easily, we split the video into small segment using scene change detection. In case of video services and copyright related business models, it is need to technology that detect near-duplicates, that longer matched video than to search video containing short part or a frame of original. To detect near-duplicate video, we proposed motion distribution and frame descriptor in a video segment. The motion distribution descriptor is constructed by obtaining motion vector from macro blocks during the video decoding process. When matching between descriptors, we use the motion distribution descriptor as filtering to improving matching speed. However, motion distribution has low discriminability. To improve discrimination, we decide to identification using frame descriptor extracted from selected representative frames within a scene segmentation. The proposed algorithm shows high success rate and low false alarm rate. In addition, the matching speed of this descriptor is very fast, we confirm this algorithm can be useful to practical application.
Using differential scanning calorimetry (DSC), changes underwent by a mixture of $\alpha$-lactalbumin ($\alpha$-La) and $\beta$-lactoglobulin ($\beta$-Lg) during heat treatment were studied, yielding useful information for the dairy industry. Results of the DSC showed that the heat denaturation temperature of the hobo-$\alpha$-La was higher than that of apo-$\alpha$-La, suggesting hole-$\alpha$-La‘s greater stability. The denaturation temperature of a mixture of holo-$\alpha$-La and $\beta$-Lg was also slightly lower than that of holo-$\alpha$-La alone. The denaturation temperature of an apo-$\alpha$-La and $\beta$-Lg mixture was higher than that of holo-$\alpha$-La and $\beta$-Lg, suggesting that the heat stability of apo-$\alpha$-La was increased by $\beta$-Lg. Based on these results, it is possible to conclude that a mixture of holo-$\alpha$-La and $\beta$-Lg is more intensively affected by an increase in temperature than other samples, and that free sulphydryl groups seem to take part in this heat-induced denaturation.

The purpose of this study was to develop a measurement scheme that assesses organizational performances in library department unit level by applying PCSI model, a Public-service Customer Satisfaction Index. Specifically, this study adopted the Antecedent Model, a component of the PCSI's three-part model, that consists of a total of 12 service quality indices. The study selected a large-scale library as a case to analyze and design a method. We analyzed the library's organizational missions and goals set by each of its six departments, and then mapped them with each of the 12 service quality indices. This mapping was further developed as a work analysis scheme of the library and as a measurement tool. A total of 341 library users participated in a survey that was designed to assess 12 service quality indices. As a result service quality was measured for each index, which in turn, calculated the library's service performance index for both entire and individual units of the library. The results reveled the measurement tool useful in assessing service performances for both individual unit and the entire library.
Parish nursing is a community health nursing role developed in 1983 by Lutheran chaplain Granger Westberg. An increasing emphasis on holistic care, personal reseponsibility for a healthy lifestyle, and changes in healthcare delivery systems have undoubtedly facilitated the establishment and nurturance of an innovative nursing role in the community. Parish nurses are functioning in a variety of church congregations of various denominations. The parish nurse is a educator, a personal health counselor, a coordinator of volunteers. The parish nurses helps people relate to the complexed medical care system and assists people to integrate faith and health. The autors conducted a study on pastor's expectations from parish nurses. Results of this study will be useful to those instrumental in planning, initiating, supporting, and evaluating a parish nurses program The research was done on 130 pastors in Taegue and Kyong Sang Buck Do, of various ages ranging from their 20's to 60's: and pastoring churches of various sizes, ranging from under 100 to over 300 members. 94.6% agreed that they needed a parish nurse on their staff; and 86.2% said they wanted to start a parish nurse program in their churches if certain basic conditions were met. The pastors responded that some would hire the nurses on a full-time basis(22.3%), a part -time basis (37.7%) or use volunteer nurses (40%). The pastors said they would expect the following from a parish nurse: health counselling (80.0%) regular health check-ups (78.5%) health care for the elderly (78.5%) health information and education (72.3%) hospice care (72.3%) visiting sick church members at home (69.2%) arranging and training volunteers to help the seek (59.2%) health care for expectant mothers (50.0%) introducing and taking people to health care facilities (46.2%) The pastors were surveyed about specific areas of health education they would want the parish nurse to teach(for example, high blood pressure and heart disease prevention and management(76.2%) ; stress management(74.6%); and diabetes prevention and management(73.8%). The pastors were surveyed about specific areas of health counselling they would expect the parish nurse to do (for example, drug abuse, (73.1), alcohol abuse(64.6%), marriage conflict(60.0%), recovery after the loss of a loved one(56.9%), and women's conflict with parents-in-law(53.8%). The pastors were surveyed about types of things they would want included in regular health check-ups, what they would want a parish nurse to do on home visits, and what they would want included in home care for the elderly. They were also surveyed on what kind of spiritual care they would like parish nurses to give. Most (90.7%) wanted their parish, parishioners to be involved in the parish nurses program as volunteers, and in a variety of ways(such as visiting sick in their homes(68.5%) and helping with housework(63.1%) and taking sick people to health facilities(60%). Parish nurses role, activities, and boundaries of practice should be continuously monitored and refined and a 'case manager' should be conceptualized as an additional or all-encompassing role. An initial parish / community needs and readiness assessment should be done prior to establishing a program to detemine if the congregation is ready, willing, and able to support such a position for at least a 2 to 3 year period.
Purpose: The aim of this study is to evaluate if the Ilizarov external fixation procedure with axial compression can help to obtain fusion across the ankle joint in patients with a high risk of nonunion. Materials and Methods: From January 2006 to December 2015, the study reviewed 17 patients who underwent ankle arthropathy with a high risk of nonunion and who underwent ankle fusion using the Ilizarov external fixator with axial compression and auto bone grafting. After the lateral surface of the ankle joint was exposed through a lateral trans-fibular approach, massive removal of the articular cartilage and excision of any loose or avascular bone were done. With the cortical bone harvested from the pelvis as corticocancellous bone blocks, we inserted the two cortical blocks longitudinally into the anterior and posterior part of the free ankle space from lateral to medial to make the rectangular chamber to fill the cancellous bones. After the Ilizarov external fixator was equipped, we tightened the frame by 5 mm to compress the bone graft space. We accessed the American Orthopaedic Foot and Ankle Society (AOFAS) AnkleHindfoot score both preoperatively and postoperatively. Results: The average age at the time of operation was 63.4 years (range, 47~78 years). The mean frame time was 17.4 weeks (range, 15~23 weeks). The average follow-up period was 3.7 years (range, 2~6 years). Osseous fusion was obtained in 15 patients (88.2%). There were two stable pseudarthroses among the rheumatoid arthritis patients, and we continued their follow-up. The mean AOFAS AnkleHindfoot score improved from 48.5 to 73.7 points. Conclusion: Ankle arthrodesis using the Ilizarov external fixation with axial compression and auto bone grafting on the ankle arthropathy that had difficult conditions to achieve union is considered one of the useful methods with a correspondingly low incidence of complications.
Background: Tetrahedral-mesh geometries can be used in the MCNP code, but the MCNP code accepts only the geometry in the Abaqus input file format; hence, the existing tetrahedral-mesh models first need to be converted to the Abacus input file format to be used in the MCNP code. In the present study, we developed a simple but useful computer program, TET2MCNP, for converting TetGen-generated tetrahedral-mesh models to the Abacus input file format. Materials and Methods: TET2MCNP is written in C++ and contains two components: one for converting a TetGen output file to the Abacus input file and the other for the reverse conversion process. The TET2MCP program also produces an MCNP input file. Further, the program provides some MCNP-specific functions: the maximum number of elements (i.e., tetrahedrons) per part can be limited, and the material density of each element can be transferred to the MCNP input file. Results and Discussion: To test the developed program, two tetrahedral-mesh models were generated using TetGen and converted to the Abaqus input file format using TET2MCNP. Subsequently, the converted files were used in the MCNP code to calculate the object- and organ-averaged absorbed dose in the sphere and phantom, respectively. The results show that the converted models provide, within statistical uncertainties, identical dose values to those obtained using the PHITS code, which uses the original tetrahedral-mesh models produced by the TetGen program. The results show that the developed program can successfully convert TetGen tetrahedral-mesh models to Abacus input files. Conclusion: In the present study, we have developed a computer program, TET2MCNP, which can be used to convert TetGen-generated tetrahedral-mesh models to the Abaqus input file format for use in the MCNP code. We believe this program will be used by many MCNP users for implementing complex tetrahedral-mesh models, including computational human phantoms, in the MCNP code.
Octagonal green glass bottle with long neck(녹유리장경각병) was found in the tomb of the princess Hwayu who was King Youngjo's daughter by a concubine while the tomb was exhumed and buried in another place around Bucheon City, Gyeonggi-do. This octagonal glass bottle is dark green. It was made in AD 1736-A1795 because it was cngraved an inscription of "건륭년제" the bottom. This glass bottle was taken an X-ray radiography and tested adhesives and restoration materials for the conservation. Loctite 401 was suitable as considering the translucency of the glass bottle, good adhesive property and reversibility of the adhesive so it was chosen. A minute piece of the glass was analyzed the composition and lead isotope ratio. Major chemical composition of the glass bottle consisted of SiO2, K2O, and PbO system and the ratio was 68: 18.5:5.7. Green color of glass bottle was due to Fe2O3 and CuO. When the glass bottle was made, quartz as raw material of silica and K2O as natural saltpeter(KNO3) were utilized. As a result of lead isotope ratio analysis, it was suggested that the galena as raw material of lead for glass making came from the southern part of China. These results are expected to become useful data in background of glass culture and circulation study of old glass.
Three-year-old Pinus koraiensis seedlings, transplanted in brown forest soils originating from granite were treated with simulated acid rain of pH concentrations 5.6(control), 4.0, 3.0, 2.5 and 2.0 for 210 days from April 21 to November 17, 1999. Visible injury of the seedlings were observed at the pH 2.0 and pH 2.5 treatments. The total dry weight of the seedlings decreased at pH 2.0 treatment compared with that of the control, and T/R ratio increased at pH 2.0 treatment compared with others. The elements in each part of the seedlings, concentrations of Ca, P and content of chlorophyll in needles increased at the pH 2.0 treatment compared with the control. The concentration of N in the needles of the seedlings increased as the soil pH decreased. As the treated pH was lowered, soil pH has decreased, and concentrations of Ca, Mg, Al, and Mn increased, especially at pH 4.4. In addition, there was a strong correlation(r=0.90, p<0.05 ; r=-0.94, p<0.01) between the dry weight of the seedlings and the pH and Al concentration of the soils. Therefore, the pH and Al concentration in the soil may be useful indicator for assessing the effect of acid rain on the growth of woody plants.

The purpose of this study was to find out the way to activate the Education of Korean Traditional foods and culture from middle school subject, Technology and Home Economics Education. We investigated the middle school students' perception and needs for the Education of Korean Traditional foods and culture in their educational curriculum. This study was carried out by using a self-administered questionnaire and 600 middle school students in Gyeonggi province were participated. Most of subjects took the Education of Korean Traditional foods and culture as a part of Technology and Home Economics Education. They recognized that this lecture is necessary and effective, since it is of great help to their life. However, lecture was descriptively given by teacher and not actively participated by students. Therefore, students requested for more practical methods of teaching and learning. They also desired that the education should comprise what will be helpful in a real life. These results suggested that current teaching and learning methods should be corrected and complemented in such a way as to reflect relevant contents and learners' demands which are useful in a real life, so that the Education of Korean Traditional foods and culture may be conducted through middle school subjects of Technology and Home Economics Education in an effective way at school.

Kinect depth sensor, a depth camera developed by Microsoft as a natural user interface for game appeared as a very useful tool in computer vision field. In this paper, due to kinect's depth sensor and its high frame rate, we developed a distance measurement system using Kinect camera to test it for unmanned vehicles which need vision systems to perceive the surrounding environment like human do in order to detect objects in their path. Therefore, kinect depth sensor is used to detect objects in its field of view and enhance the distance measurement system from objects to the vision sensor. Detected object is identified in accuracy way to determine if it is a real object or a pixel nose to reduce the processing time by ignoring pixels which are not a part of a real object. Using depth segmentation techniques along with Open CV library for image processing, we can identify present objects within Kinect camera's field of view and measure the distance from them to the sensor. Tests show promising results that this system can be used as well for autonomous vehicles equipped with low-cost range sensor, Kinect camera, for further processing depending on the application type when they reach a certain distance far from detected objects.
