Purpose : The purpose of this study was to determine the effect of pelvic floor muscle exercise (PFME) on an unstable support surface on maximal inspiratory pressure (MIP), maximum expiratory pressure (MEP), and abdominal muscle thickness as a method for effective PFME. Methods : This study was performed on 22 subjects. They were matched and divided into two groups based on body mass index; the experimental group (EG) performed PFME on a foam roller (n= 11), the control group (CG) performed PFME on a stable support surface (n= 11). Kegel exercise was performed with 10 seconds of contraction, 10 seconds of relaxation, and 4 sets of 10 reps per set. Both of group executed the exercise 3 times a week for 2 weeks. MIP and MEP was measured using a spirometer. Abdominal muscle thickness was measured using ultrasound. The paired t-test was used to compare difference on each group and the comparison between groups was analyzed using the independent t-test. A significance level of α= .05 was used to verify statistical significance. Results : The EG showed a significant increase in the MEP (p<.05). The CG showed a significant increase in the MEP (p<.05). There was no significant difference in the two groups (p>.05). The EG showed a significant increase in the external oblique, internal oblique and transverse abdominis (p<.05). The CG showed a significant increase in the internal oblique (p<.05). There was no significant difference in the two groups (p>.05). Conclusion : Based on the results of this study, additional research should be conducted to correct the limitations of this study to confirm that PFME performed on a foam roller has a positive effect on respiratory muscle strength and abdominal muscle thickness.

Korean Academy of Film Arts (KAFA) is the film school run by Korean Film Council (KOFIC). KAFA was established in 1984, benchmarking American Film Institute (AFA) and in order to foster manpower for Korean Movie under the US's pressure of domestic movie market opening in Korea. The Korean Movie market was open to the world by 1987 and suffered from the low Korean-produced movie market share of around 20% in the domestic market from 1987 to 1998. During the last 30 years, KAFA plays the key role in the Korean movie making industry. Of 520 of number of their alumni, the number of directors is 101, 33 of cinematographers, 18 of producers and 21 of professors in universities' film departments. Korean Directors, Bong Joon-ho of (2013) and topped over 10 million domestic admissions to become the most-watched Korean films of all time. Now, with KAFA's relocation to Busan following with KOFIC, their new roles are promotion of the film industry in Busan, recruiting and educating new talented Korean and foreign student filmmakers, becoming an international film school.

봄철 해역에 따른 부착미세조류의 영양성분 변화를 알아보기 위하여 본 실험을 수행하였다. 실험은 울진, 부안, 완도, 부산 지역에서 봄철인 2~4월 동안 실시되었으며 실험간의 오차를 줄이기 위해 실험 시작일의 차이는 최대 10일 이내로 하였다. 배양을 위한 실험해역의 기초 조사로 배양지역 연안해수의 수온, 염분, pH, 총질소, 총인, Chlorophyll-a의 측정을 하였고 각 지역의 부착미세조류를 수확하여 영양분석을 하였다. 실험에 사용된 파판은 전복 종묘생산에 이용되는 규조배양용 파판과 틀을 이용하였고 실험기간은 총 8주 동안 실시하였다. 2주마다 파판을 수거한 뒤 부착된 미세조류를 부드러운 솔로 분리하여 원심 분리한 후 지방산과 아미노산의 측정을 하였다. 또 각 시료의 일정량을 Sedwick-rafter counting chamber를 이용하여 검경ㆍ계수한 후 이를 단위면적당 개체수(cells/$\textrm{cm}^2$)로 환산하여 biomass를 구하였다. 봄철 지역간의 수온의 범위는 13.9~16.6$^{\circ}C$를 보였으며 울진이 가장 높고 부안지역이 가장 낮았다. 염분은 부안지역의 염분이 평균 2$\textperthousand$ 이상 낮았으며 그 외의 지역은 큰 차이가 없었다. pH는 7.77~8.21의 범위를 보이고 있었으며 질산염 농토는 부산이 0.265mg/$\ell$로 최대값을 보였고 울진이 0.032mg/$\ell$로 제일 낮았다. 인산염 농도는 완도지역이 0.018mg/$\ell$로 최대치를 보였고 부안은 검출되지 않았다.

Construction of roof structure, cable suspended structure, for Pusan main stadium is adapted a lifting method that is VSL lifting system. 5 precesses are practiced for erection of the roof structure including the first lifting process for erection of upper cables and the second lifting process for erection of lower cables. Since all cables of this roof structure with two open speller sockets are determined their length, some cable were wrong length, the roof structure would be unstable. But At complete of erection for the roof structure each cab3e is attained to theoretical tension force with average $4\%$ errors.

This paper proposes a contrast enhancement technique which stretches the intensity surfaces of image to improve the quality of the digital photos. The proposed method enhances the contrast of image by stretching the intensity surface of the original image to the maximum range of the output image in proportion to the distances between the original intensity surface and upper, lower intensity surface, respectively. The upper and lower intensity surfaces are generated from the original intensity surface by gaussian smoothing. In the experiments, digital color images in a variety of illumination conditions were used and the proposed method was compared with other several existed image enhancement algorithms, which are histogram stretching, surface stretching, histogram equalization, gamma correction and retinex. It was proved that the experimental results were more natural visually without deterioration of gradation.

Cotton fabrics were treated with gelatin to improved their dyeability, color strength toward cochineal dye. Gelatin were used as the protein. Gelatin is containing a large number of hydrophilic groups. Pad-dry-cure method was used for the treatment process(10g/L concentration). The scanning electron micrograph showed the gelatin was deposited on the surface of cotton. Pretreated fabrics were mordanted with 10%(owf) alum. Then the fabrics were dyed with cochineal. Compared with original cotton fabric the K/S value with cochineal dyes was significantly improved on gelatin modified cotton. Treating cotton with 10g/L concentration gelatin offered higher cochineal adsorption. The dyeability of pH 4 yielded the highest color strength. In dyebaths of a ratio of ethanol and water such as; 10:0, 9:1, 8:2, 7:3, 6:4, 5:5, 4:6, 3:7, 2:8, 1:9, 0:10, fabrics were dyed. The ratio of ethanol and water had powerful effects on solution polarity. Cochineal dye uptake showed maximum value, when the proportion of ethanol and water was 9:1. Dyeing at increased temperatures and with increased time resulted in higher dye uptake and reddish-purple color(5RP). The washing fastness was 1-2grade, and the fastness to light was 2-3grade.

Purpose: This study examines the relationship between the occurrence of migraine headaches and three constitution types of Korean Hand Therapy (Seogeum Therapy). Methods: A total of 684 subjects comprised the study data: 500 healthy individuals and 184 migraine sufferers. The data were analyzed according to three constitution types of Seogeum Therapy. The subjects were classified according to their constitution types and body sides. Results: There were significant differences between the three types. Among the healthy group, the Yang Type and Shin Type Constitutions were more predominant than the Eum Type; the Yang and Shin Types were also more predominant than Eum Type with respect to both sides of the body. Among the migraine sufferers, the Eum Type Constitution was more predominant than the Eum Type; the Eum Type was also more predominant than the other types with respect to both sides of the body. Conclusions: These results suggest that the Eum Type Constitution might be associated with migraine headaches.

The purpose of this study is to investigate operating practices of human resources nourishing institutions and analyze the degree of satisfaction to the e-learning learners in Busan. This study adopted a questionnaire method in research of 70 human resources nourishing institutions and 758 e-learning learners in Busan area for empirical analysis. Techniques used in analyzing data was frequency analysis. SPSS for windows programs were applied in the analysis. The major findings of this study are as follows. First, it is found that there is a widespread affirmative perceptions in the fields of both operating practices and satisfaction on e-learning. Second, however, it is also found that more efforts needed to be made in some areas such as method for effective e-learning and the management of programs, and more concerns should be need to the age group of fifty-over. These groups are short of understanding and acceptance of e-learning environment.
