  • Background: The gluteus medius (Gmed) plays a critical role in maintaining frontal plane stability of the pelvis during functional activities, such as one-leg lifting. Side-lying hip abduction (SHA) has been used as a dynamic test to evaluate Gmed function. However, the abduction force of the lower leg against the floor is not controlled during SHA. Therefore, hip abduction performance with contralateral adduction in the side-lying position (HAPCA) can be proposed as an alternative method to assess performance of hip abduction. If the number of HAPCA is related to the lateral pelvic shift distance, a new quantitative measurement for hip abductor function may be presented. Objects: This study aimed to investigate the relationship between the number of successful HAPCA and the lateral pelvic shift distance during one-leg lifting. Methods: Thirty healthy participants were recruited, and lateral pelvic shift distance was measured during one-leg lifting test using two-dimensional analysis. The number of successful HAPCA was counted when participants touched both target bars at the beat of a metronome. Results: There was a negative correlation between the number of HAPCA and lateral pelvic shift distance during one-leg lifting (r = -0.630, p < 0.05). The number of HAPCA accounted for 39.7% of the variance in the lateral pelvic shift distance during one-leg lifting (F = 18.454, p < 0.001). Conclusion: The number of successful HAPCA is significantly correlated with lateral pelvic shift distance during one-leg lifting. This finding suggests that HAPCA can be proposed as a new measurement for hip abductor performance and more research is needed on its relationship with hip abductor strength.

  • In this paper, I will explore disparate voices embedded in the interactions of stories in which personal, cultural, historical, and mythical consciousness brings up diverse ideas about the experiences of Native Americans. The accommodation of differences and changes is clearly manifested through the healing ceremony of Tayo, which poses some practical questions: what could be the authentic tradition of Native Americans?; which direction should it be led to? As these questions suggest, Tayo needs to think over and work through the way that Native oral stories will enrich the signification of being Indian within multicultural U. S. society. In other words, Tayo should transfer the oppositional relationship between Anglo and Native American world into an interactive one to bring forth new meanings concerning their interactions. As a hybrid, Tayo begins to recognize that his fragmented consciousness could represent the pervasive but surmountable anxiety about the cultural clash between Native and White Americans. Going through the multiple layers of his stories, Tayo learns that Native Americans need to hold a balanced viewpoint firmly: this demonstrates that storytelling brings restoration and renewal to him. As a result of Betonie's healing ceremony and his intimate relationship with Ts'eh, Tayo comes to have a holistic comprehension about how all the living things are interconnected to one another. After acquiring this recognition, Tayo succeeds in his quest to get back Josiah's cattle and recovers his identity as a Laguna Pueblo Indian, still letting diverse voices, cultures, and stories flow into the process of storytelling. As the last scene in which the conversations among Tayo, Auntie, and Grandmother took place illustrates, Tayo has newly secured a position that will require him to create a new, alternative story, not just repeating previous stories.

  • Referred to as a 'media war,' there is a fierce competition for media discourse between different countries. Twenty four hour global news channels like Al Jazeera, France 24, RT, NHK World, China's CCTV and teleSUR emerged to offer their own perspectives and stance in the global society, and to face the monopolization and distorted information created by the hegemony of English news channels which have swayed international public opinions for a long time. As a tool of public diplomacy, the media's role in determining the image of the nation and winning the 'Hearts and Minds' of the international community is decisive, but it cannot be said that they all have a similar influence or play a positive role in media diplomacy. A global news channel, which is both a media diplomatic subject and a journalism organization, can be in the position of acting as a public relations organization or a propaganda agency for the government depending on the regime's attitude because most of global news channels receive support from the government. Sometimes it is difficult for these media to implement quality journalism because of financial difficulties. Media discourse also has limitations in that it is dependent upon changes in foreign policy of its own government. This study examines the current status of global news channels, the dilemma these channels are facing, and suggests some potential directions that can be taken by global news channels in order to become more effective. It is becoming increasingly important for all nations to respond to distorted information about their own countries, to appropriately identify various issues and changes in the international community and to convey their views and positions to the international community. For now, there is a lack of awareness about the importance of media diplomacy in Korea: There are many English-language media, but as yet no global news channel which could have an influence on the international stage. However, there seems to be some understanding about the need for the media to present the Korean alternative discourse to the senseless dependency on Western media. We hope that this study will be an opportunity to think in depth about the attitude of the Korean global media, whether existing global media or new global news channels, in order to help them become more effective in media diplomacy.

  • The widespread adoption of aluminum slab formwork in modern construction, evident in both domestic and international projects, offers numerous advantages. However, a critical challenge persists regarding the dismantling process for these slabs. The current industry standard involves dropping the slabs to the ground floor upon removal. This practice raises several concerns, notably the generation of significant noise pollution that disrupts nearby communities. More importantly, the risk of worker injuries due to falls from height during the dismantling process is a serious safety hazard. Additionally, the impact from dropping the slabs can damage the aluminum itself, leading to increased replacement costs. These drawbacks necessitate the exploration of alternative dismantling techniques that prioritize worker safety, material sustainability, and overall process efficiency. Accordingly, in this study, when the entire first-generation slab formwork of an apartment house is simultaneously lowered to a reachable position for workers, it is then disassembled and lifted for transport to the next floor. This approach has the potential to demonstrate improvements in safety, quality, economy, and process efficiency.

  • Drone-mounted hyperspectral sensors (DHSs) have revolutionized remote sensing in agriculture by offering a cost-effective and flexible platform for high-resolution spectral data acquisition. Their ability to capture data at low altitudes minimizes atmospheric interference, enhancing their utility in agricultural monitoring and management. This study focused on addressing the challenges of radiometric and geometric distortions in preprocessing drone-acquired hyperspectral data. Radiometric correction, using the empirical line method (ELM) and spectral reference panels, effectively removed sensor noise and variations in solar irradiance, resulting in accurate surface reflectance values. Notably, the ELM correction improved reflectance for measured reference panels by 5-55%, resulting in a more uniform spectral profile across wavelengths, further validated by high correlations (0.97-0.99), despite minor deviations observed at specific wavelengths for some reflectors. Geometric correction, utilizing a rubber sheet transformation with ground control points, successfully rectified distortions caused by sensor orientation and flight path variations, ensuring accurate spatial representation within the image. The effectiveness of geometric correction was assessed using root mean square error(RMSE) analysis, revealing minimal errors in both east-west(0.00 to 0.081 m) and north-south directions(0.00 to 0.076 m).The overall position RMSE of 0.031 meters across 100 points demonstrates high geometric accuracy, exceeding industry standards. Additionally, image mosaicking was performed to create a comprehensive representation of the study area. These results demonstrate the effectiveness of the applied preprocessing techniques and highlight the potential of DHSs for precise crop health monitoring and management in smart agriculture. However, further research is needed to address challenges related to data dimensionality, sensor calibration, and reference data availability, as well as exploring alternative correction methods and evaluating their performance in diverse environmental conditions to enhance the robustness and applicability of hyperspectral data processing in agriculture.

  • Rapid urbanization and population increasing are making a high-rise residential building and high-density residential area. According to spacial concentration of population is occurred road traffic noise problem. Now we are popularly using almost only noise barrier installation, but it makes many disfunctions such as poor landscape, low noise barrier performance and crimes. The purpose of this research is to figure out which is best method one the traffic noise management. Alternative are composed to building layout type ($30^{\circ},\;90^{\circ},\;180^{\circ}$), separation between road and residential building, noise barrier types(noise barrier only, noise barrier and forests and etc). The noise barrier are shown to reduce barrier and building layout angle $30^{\circ}$ position is the best comparing with horizontal and vertical layouts. The gab distance is decreased approximately noise level 5dB(A). We figured out there are noise important method except noise barrier wall and it was analyzed how much decreased. This can be very useful before making a road planning and residential building design.

  • If a patient wearing arm sliding due to shoulder dislocation or fracture is impossible with abduction, the velpeau view is performed instead of superior-inferior axial projection view. However, it aggravates the patient's pain because it is difficult for the patient with dislocation or fracture to pull back the shoulders. Therefore, I suggest a new method of the 'modified velpeau view' that allows patients to lower their heads at examination. In order to investigate the easiness of fixing posture at examination and clinical utility, I conducted a study comparing the bone structures at the velpeau view and those at the modified velpeau view depending on wall-bucky and the patients' leaning forward angle ($30^{\circ},\;45^{\circ},\;60^{\circ}\;and\;75^{\circ}$), with the subjects of 20 velpeau view-prescribed patients amongst who had come to my hospital suspected of dislocation of shoulder or fracture and 30 healthy people from October of 2009 to January of 2010. Department of radiologists and orthopedics specialists evaluated the pictures for scales 0 to 5(best grade) under the given criteria. As a result of comparison in bone structures depending on wall-bucky and the leaning-forward angle in the group of healthy people, the velpeau view and the modified velpeau showed a similar diagnostic utility at $45^{\circ}$ and $60^{\circ}$. The picture evaluation result for proving diagnostic value showed that the anterior and posterior of shoulder heads and the anterior and posterior of glenoid fossa could be observed in the velpeau view; on the other hand, besides these areas acromioclavicular joint and coracoid process could be viewed in the modified velpeau view. This result verified that the modified velpeau view could replace the velpeau view for its diagnostic value as an examination method. This result, moreover, suggests that the modified velpeau view needs to be studied and improved from a variety of perspectives not only for an alternative for patients having troubles with the velpeau view position but also for clinical application of new test method for diagnosis of shoulder disorders other than dislocation of shoulder or fracture.

  • It needs to put into practice the systems analysis in the analysis of some operations and status of library for the purpose of systematizing the work of reforming in the new easier form to process, to storage, to retrieve and to make use of the increasing informations and data of library. In this study, some of systems which are generally using in every library was caught in the case study of K university library. Having analyzed them with the two methods of the flowcharting and mathematical analysis, we found the obstructive factors in operation. As the result of this research, it was gained the new system as the alternative one. A. Alternative System B. Advantages of alternative systems 1. In the reference room When it converts the present system into the new system, it can profit 6.771 won/user (13.815won-7.044won=6.771 won). Therefore, a half the average required cost of the present system can be saved. If this saving would be alloted for the cost 33,000won required to make the cataloging cards, it would be taken for 94 days (33,000 won ${\div}$ 6,771 won/user=4,874users. 4,874users ${\div}$ 52users/day=94days) to get it. The saving cost/year by the new system will be 95,417 won, and in the first year the initial cost (33,000won) reduces the saving cost to 62,417won. 2. In the periodical room The average required time for using the materials of the present system is 17 minutes/user and the average required cost/user is 23.775won, while the average required time of the new system is 4 minutes and the average required cost/user is 5.33won. Therefore, the new system has profit 4 times of the present system. Accordingly, it occurs when the dispersed periodical materials get together. 3. In the classification and cataloging When one processes - the oriental books - by the Linear Programming Technique, the maximum of the process can be increased from 11.6 volumes per librarian of the present system to 12 volumes per librarian of the new system increased 0.4 volume in a day, and cataloging by the manual printer can be shorten from 3 minutes per card of the present system to 1.5 minutes per card of the new system. Consequently, we can complete the other operations (books equipment, updating of cataloging cards, etc.) with 141 minutes which are saved in the course of the afore-mentioned works. 4. In the status of collections The average growth rate of 4 years from 1968 to 1971 is 9.825 %, and that of the purchased materials is 6.2% similar to the advanced nations, but it has the different position from 215,000 volumes by the Standard Degree for Establishment of College and University, and the difference between the total collections 151,671 volumes and Dunns' growth model ($N_t=N_oe^{-at}$) claimed by Leimkuhler 155,297 volumes in 1971 is 3,626 volumes, and for the purpose of compensation the difference, we found the fact that it needs to have the increased budget of 24~30% per year, Thus, if the budget of 24~30 % per year. Thus, if the budget would be increased per year as the rate of the afore-mentioned figure, it would be reached at the Standard Degree for Establishment of College and University in 1975, and thereafter, it can be decreased to the lebel which is able to maintain the growth rate of 5~6% per year.

  • Purpose: The plan proposed by the Ministry of Health and Welfare in 2012 did not reflect the position of nurses and focused only on how to increase the number of nurses. There is a need for coming up with a specific and viable alternative plan considering the qualitative aspect of nursing, delegation of nursing tasks, the in-death analysis of the reasons for leaving the nursing profession, and the legal standards based on varying nursing tasks. Methods: Drawing on a review of existing literature, this report was written to examine policy directions and the factors that influence the institutional environment that regulates the supply and demand of the nursing workforce in Korea. Results: Implementing the government's plan for introducing a new type of nurse, the registered practical nurse, which generally requires a two-year associate's degree, must be reconsidered. Also, a concrete plan to make use of unemployed nurses and to close the salary gap between nurses working at hospitals in cities and those working at hospitals in rural areas must be prepared. Furthermore, there is a need for introducing a new rating system aimed at boosting the quality of nursing care in small-and medium-sized hospitals, thereby increasing the number of nursing professionals who provide high quality care. Conclusion: In preparation for expected poor quality of care and looming unemployment crisis due to the increase in the number of nursing professionals, a practical and concrete plan for the supply and demand of the nursing workforce should be made. The Korean Nurses Association should mount a profession-wide campaign to make the government formulate a new and viable policy on the supply and demand of the nursing workforce.

  • Purpose: Accurate localization of the lumpectomy cavity during accelerated partial breast radiation (APBR) is essential for daily setup to ensure the prescribed dose encompasses the target and avoids unnecessary irradiation to surrounding normal tissues. Three-dimensional ultrasound (3D-US) allows direct visualization of the lumpectomy cavity without additional radiation exposure. The purpose of this study was to evaluate the feasibility of 3D-US in daily target localization for APBR. Materials and methods: Forty-seven patients with stage I breast cancer who underwent breast conserving surgery were treated with a 2-week course of APBR. Patients with visible lumpectomy cavities on high quality 3D-US images were included in this analysis. Prior to each treatment, X-ray and 3D-US images were acquired and compared to images from simulation to confirm accurate position and determine shifts. Volume change of the lumpectomy cavity was determined daily with 3D-US. Results: A total of 118 images of each modality from 12 eligible patients were analyzed. The average change in cavity volume was 7.8% (range, -24.1% to 14.4%) on 3D-US from simulation to the end-of-treatment. Based on 3D-US, significantly larger shifts were necessary compared to portal films in all three dimensions: anterior/posterior (p = 7E-11), left/right (p = 0.002), and superior/inferior (p = 0.004). Conclusion: Given that the lumpectomy cavity is not directly visible via X-ray images, accurate positioning may not be fully achieved by X-ray images. Therefore, when the lumpectomy cavity is visible on US, 3D-US can be considered as an alternative to X-ray imaging during daily positioning for selected patients treated with APBR, thus avoiding additional exposure to ionizing radiation.
