Purpose: The purpose of this study was to evaluate the clinical efficacy of enhancing deficient interdental papilla with hyaluronic acid gel injection by assessing the radiographic anatomical factors affecting the reconstruction of the interdental papilla. Methods: Fifty-seven treated sites from 13 patients (6 males and 7 females) were included. Patients had papillary deficiency in the upper anterior area. Prior to treatment, photographic and periapical radiographic standardization devices were designed for each patient. A 30-gauge needle was used with an injection-assistance device to inject a hyaluronic acid gel to the involved papilla. This treatment was repeated up to 5 times every 3 weeks. Patients were followed up for 6 months after the initial gel application. Clinical photographic measurements of the black triangle area (BTA), height (BTH), and width (BTW) and periapical radiographic measurements of the contact point and the bone crest (CP-BC) and the interproximal distance between roots (IDR) were undertaken using computer software. The interdental papilla reconstruction rate (IPRR) was calculated to determine the percentage change of BTA between the initial and final examination and the association between radiographic factors and the reconstruction of the interdental papilla by means of injectable hyaluronic acid gel were evaluated. Results: All sites showed improvement between treatment examinations. Thirty-six sites had complete interdental papilla reconstruction and 21 sites showed improvement ranging from 19% to 96%. The CP-BC correlated with the IPRR. More specifically, when the CP-BC reached 6 mm, virtually complete interdental papilla reconstruction via injectable hyaluronic acid gel was achieved. Conclusions: These results suggest that the CP-BC is closely related to the efficacy of hyaluronic acid gel injection for interdental papilla reconstruction.

In this paper, designed a high speed 2-dimensional DCT(Discrete Cosine Transform) design using the distributed arithmetic system applicable to MPEG, JPEG, H26x system for image data compression. This system is using the DA, vector processing and pipeline. Designed in this paper, consists of datapath unit and controller. This system is compared to the pipelined 2-D DCT. As the result, This system processes 12 frames/sec for 720 × 480 size, therefore, that This system is prior to pipelined 2-D DCT system was found.

In this paper, IDCT that can decode still and moving image is designed. For high performance of data processing, this system is applied pipelined architecture to IDCT system, designed in this paper, consists of datapath, controller and clock generator, and in order to test design area, processing time and power consumption, this system is compared the sequential IDCT system. As the result, the pipelined IDCT system processes 14 frames/sec for 352 × 240 size, therefore, that the pipelined IDCT system is prior to sequential IDCT system was found.

The purpose of this study was to survey and analyze the response of civil servants on the participation in sports activities and the cause of barrier in sprots participation with 400 civil servants (female:100, male:300) on the Yangpyong city in Kyongki province were answered by the questionnaire. Analysis of the data with 376(female:90, male:286) for the evaluation of the questionnaire can be acquired the more basis materials of sports environment for the civil servants. As result, we have the conclusion as follow. 1. The participation in sports activities among civil servants. The servey of the participation in sports activities among civil servants is as follows. The frequency of playing sports is 1∼2 in a week. The time last 30min.∼1hr. The preferance time is in the aftermoon. The major reason of playing sports is promotion of health. The most popular sports is jogging and marathon. 2. The cause of barrier in sports participation among civil servants is as follows in order. 1) Dissatisfaction of sports program 2) Difficulty of approach to sports club 3) Insufficiency of social support 4) Shortage of time 5) Low nterest in sports 6) Enerfation 7) Shortage of physical strength.

The purpose of this study was to survey and analyze the response of middle, high-school students on the barriers to exercise and sport with 600 students(male:330, female:270) on the yangpyong city in kyongki province were answered by the questionnaire. Analysis of the data with 565(male:311, female:254) for the evaluation of the questionnaire can be acquired the more basis materials of sports environmnet for the middle, high-school students. As result, we have the conclusion as follow. 1. In their sex and factor of sport barriers. male is a bar to according to priority sport program(3.05), sport club(3.00), financial support(2.91), social support(2.85), time shortage(2.73), different concern(2.34), enervation (2.13), health/physical strength(2.03) female is a bar to according to priority sport program(3.30), sport club(3.04), time shortage(2.96), different concern(2.95), social support(2.88), financial support(2.84), enervation (2.59), health/physical strength(2.14) 2.

In this paper, we implement the Modified Discrete Cosine Transform(MDCT)/Inverse MDCT(IMDCT) in MPEG audio layer 3 using HW(Hardware)/SW(Software) Co-Design methodology. The computation process of the MDCT/IMDCT is most intensive in MPEG audio layer 3. Therefore, it is very important that the MDCT/IMDCT must be implemented in HW. The eXCite in YXI Co., which inputs ANSI-C language as high-level description and outputs VHDL or(and) Verilog-HDL file in HW/SW Co-Design. As the result to simulate our design, the MDCT/IMDCT are operated in 68MHz on Stratix chip in ALTERA and in 20MHz on Excalibur chip for SoC Design
