UHD (Ultra High Definition) broadcasting technology, and UWV (Ultra Wide Vision) which is the high quality panoramic video of wide view angle based on UHD, were commercialized in Korea for the first time in the world, and those are representative realistic video technologies that maximize the user's sense of presence. By comparing the user's subjective reaction of UHD and UWV, the purpose of this study is to systematically establish the user's subjective video quality evaluation. For this purpose, a large screen projection experiment is designed by setting the screen size (4k x 2k, 8k x 2k) and content types (sports, landscape, concert) as variables to measure the user's subjective video quality evaluation and satisfaction. As a result of the study, the users' evaluation of UWV was higher than UHD in all items of subjective video quality, and satisfaction. Moreover, the results showed the significant differences depending on the video contents. Based on the results of the research, the study proposed the points necessary for the development and commercialization of UWV panoramic technology, and suggestions for the future research.

Purpose : We aimed to investigate the effects of nutritional foods on sarcopenia prevention and physical function among the elderly living in rural communities during the COVID-19 pandemic by providing customized nutrition. Methods : This study was conducted in the rural community of SCC. Participants (n=24, over age 65) were randomly assigned into a Protein group (n=12) and a Vitamin group (n=12). The protein group was given 23 g/d of protein (whey, soybean, BCAA) for 8 weeks and the Vitamin group 23 g/d of vitamin (B, C, D, E and mixed minerals such as calcium, magnesium, zinc) for 8 weeks. All participants had their body composition such as height, weight, skeletal muscle mass, body mass index, and body fat percentage, measured using bioelectrical impedance analysis (BIA) and physical function assessed using grip strength and the short physical performance battery (SPPB). Results : At the end of the intervention, there was a significant increase in skeletal muscle mass (p<.01) in the Protein group (p=.002, 4.92 %) compared to the baseline: it increased by 2.33 %. The Vitamin group had a significant increase in body fat percentage after the intervention (p=.001, 15.35 %) compared to the baseline: body fat percentage decreased by 4.49 %. There were no significant differences in left and right Grip strength/Weight, SPPB, 4-m gait speed, chair stand test, and sense of balance in both groups. Conclusion : The findings from this study suggest that 8 weeks of protein intake have a significant effect on skeletal muscle mass and body fat percentage. Protein intake helped promoting the health of the elderly in rural community during the COVID-19 pandemic. It will assist creating a foundation for providing customized nutrition for the elderly in rural community in the future.

The National Library of Korea (Sejong), which was launched in December 2013, has been in the spotlight as a specialized library for Korean policy information and as a Sejong city complex cultural facility. Nevertheless, the essential identity, organizational status, division of affairs and core competencies, policy information collection, and services of the NLK (Sejong) are weak and inadequate. Therefore, this study developed a job model for establishing an essential identity and providing high-quality policy information services nationwide and suggested a strategic organizational reorganization plan. The job model was proposed as a total of 110 by adding 38 to the existing 72. Based on this job model, the short-term reorganization model (2023-2024) changed the grade of the library director from the current grade 4 (administrative officer) to Senior Executive, and the grade of the director by division from grade 5 (secretary) to grade 4. The sub-organization has expanded the current 3 divisions (planning management, policy information, and service use) to 4 divisions (planning administration, library collection and development, policy information service, and public service and culture, with a total of 51 personnel. In the mid-to-long-term model (2025-2032), the sub-organization was expanded to 4 divisions and 1 office (planning administration, library collection and development, policy information service, public service and culture, and policy information research), and presented a total of 61 personnel. To this end, it is necessary to persuade stakeholders with the argument of advocating the Korean policy information center, which is a macro-strategic goal, and focus all capabilities on strategic reorganization and revision of 「Decree on the Organization of the Ministry of Culture, Sports and Tourism」.

This study was conducted using text mining and network theory to extract useful information for application for occupancy and performance of permit tasks contained in the permit contents from the permit register, which is used only for the simple purpose of recording occupancy permit information. Based on text mining, we analyzed and compared the frequency of vocabulary occurrence and topic modeling in five regions, including Seoul, Gyeonggi, Gyeongsang, Jeolla, Chungcheong, and Gangwon, as well as normalization processes such as stopword removal and morpheme analysis. By applying four types of centrality algorithms, including stage, proximity, mediation, and eigenvector, which are widely used in network theory, we looked at keywords that are in a central position or act as an intermediary in the network. Through a comprehensive analysis of vocabulary appearance frequency, topic modeling, and network centrality, it was found that the 'installation' keyword was the most influential in all regions. This is believed to be the result of the Ministry of Environment's permit management office issuing many permits for constructing facilities or installing structures. In addition, it was found that keywords related to road facilities, flood control facilities, underground facilities, power/communication facilities, sports/park facilities, etc. were at a central position or played a role as an intermediary in topic modeling and networks. Most of the keywords appeared to have a Zipf's law statistical distribution with low frequency of occurrence and low distribution ratio.

The purposes of this study were to a analysis of friction relation between tennis outsole and tennis playing surfaces. Tennis footwear is an important component of tennis game equipment. It can support or damage players performance and comfort. Most importantly athletic shoes protect the foot preventing abrasions and injuries. Footwear stability in court sports like tennis is incredibly important since it is estimated that as many as 45% of all lower extremity injuries occur in the foot and ankle. The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. The friction force opposes the motion of the object. Friction results when two surfaces are pressed together closely, causing attractive intermolecular forces between the molecules of the two different surfaces. The outsole provides traction and reduces wear on the midsole. Today's outsoles address sport specific movements (running versus pivoting) and playing surface types. Different areas of the outsole are designed for the distinct frictional needs of specific movements. Traction created by the friction between the outsole and the surface allows the shoe to grip the surface. As surfaces, conditions and player motion change, traction may need to vary. An athletic shoe needs to grip well when running but not when pivoting. Laboratory tests have demonstrated force reductions compared to impact on concrete. There is a correlation between pain, injury and surface hardness. These are a variety of traction patterns on the soles of athletic shoes. Traction like any other shoe characteristic must be commensurate and balanced with the sport. The equal and opposite force does not necessarily travel back up your leg. The surface itself absorbs a portion of the force converting it to other forms of energy. Subsequently, tennis court surfaces are rated not only for pace but also for the percentage of force reduction.

'Convention' refers to custom and practice as the dictionary definition; it means genre custom. Readers feel intimate with the pattern and grammar that a genre has, and they participate in the work, predicting and expecting the next in the 'truism.' So, all popular arts targeting the public have genre custom-that is, convention. A cartoon (comics) is one of the popular arts whose convention is developed most to the extent that its law comes across our mind just with the genre's name such as 'sports comics', 'detective comics' and 'romance comics.' However, although the fantasy cartoon is a genre that has been loved for a long time, it is one of the cartoon genres that has rarely been studied on its convention. There are several reasons for the lack of studies on convention of the fantasy cartoon. The most fundamental reason may be that its basic concept has not been properly prescribed. There are some precedent studies prescribing the fantasy cartoon as an extension of the fantastic literature, but it is hard to analyze convention that only fantasy cartoon has, because its range is too wide. So, this study considered J.R.R. Tolkein's 'Lord of the Ring' had made the genre custom of fantasy novel and fantasy comics, and classified concept and type of the fantasy cartoon. And through analysis of various cases, it investigated convention of the fantasy cartoon into 6 types. Genre is not the complete format. It is subdivided and differentiated, and it becomes one with other genres and makes a new one. For that reason, there exist limitations always when we study a genre convention of a certain genre. This study confesses in advance that it also has limitations as it just suggests convention of the general fantasy cartoon.

Purpose : The purpose of this study was to evaluate the gutter pathologies and the clinical results of arthroscopic treatment for ankle gutter syndrome. Materials and Methods : Seventy six patients(77 ankles) who had lesions in the ankle gutter were treated by arthroscopy. The gutter pathology could be divided into 3 categories; hypertrophic scar tissue, loose bodies and bone spurs. Fifty two patients were evaluated subjectively and functionally with authors' criteria. The follow-up period averaged 44 months(range, 2.9 year-8.5 year). Results : The incidence of the gutter lesion was $21\%$(77 ankles) among 366 ankles undergoing arthroscopy. The most common pathology was hypertrophic scar tissue. In 31 ankles$(40\%)$, the lesions were found only in gutter, and 46 ankles$(60\%)$ were associated with pathologies in other areas. All of parameters for subjective and functional evaluation were improved with statistical significance(p<0.001). Seventeen patients$(33\%)$ could returned to competitive or contact sports activity with same level of premorbid period. Conclusion : Ankle gutter is an important site of pathologies which cause chronic ankle pain, and should be explored in ankle arthroscopy. The ankle arthroscopy is a very effective treatment method fur the removal of pathologies in ankle gutter syndrome.

In this review, we described the catalogues of the rice proteome which were constructed in our program, and functional characterization of some of these proteins was discussed. Mass-spectrometry is the most prevalent technique to rapidly identify a large number of proteome analysis. However, the conventional Western blotting/sequencing technique has been used in many laboratories. As a first step to efficiently construct protein cata-file in proteome analysis of major cereals, we have analyzed the N-terminal sequences of 100 rice embryo proteins and 70 wheat spike proteins separated by two-dimensional electrophoresis. Edman degradation revealed the N-terminal peptide sequences of only 31 rice proteins and 47 wheat proteins, suggesting that the rest of separated protein sports are N-terminally blocked. To efficiently determine the internal sequence of blocked proteins, we have developed a modified Cleveland peptide mapping method. Using this above method, the internal sequences of all blocked rice proteins(i, e., 69 proteins) were determined. Among these 100 rice proteins, thirty were proteins for which homologous sequence in the rice genome database could be identified. However, the rest of the proteins lacked homologous proteins. This appears to be consistent with the fact that about 45% of total rice cDNA have been deposited in the EMBL database. Also, the major proteins involved in the growth and development of rice can be identified using the proteome approach. Some of these proteins, including a calcium-binding protein that tuned out to be calreticulin, gibberellin-binding protein, which is ribulose-1.5-bisphosphate carboxylase/oxygense active in rice, and leginsulin-binding protein in soybean have functions in the signal transduction pathway. Proteomics is well suited not only to determine interaction between pairs of proteins, but also to identify multisubunit complexes. Currently, a protein-protein interaction database for plant proteins(http://genome.c.kanazawa-u.ac.jp/Y2H)could be a very useful tool for the plant research community. Also, the information thus obtained from the plant proteome would be helpful in predicting the function of the unknown proteins and would be useful be in the plant molecular breeding.

The purpose of this study was to identify the relationship between self-empowerment and a health promoting lifestyle in climacteric women, and to provide the basic data for health promoting intervention. The subjects were 246 women who visited the sports center in Taegu, Korea and ranged in age from 40 to 59. The data was collected during the period from December 2nd to December 15th, 2001. The instruments were the revised health promoting lifestyle scale developed by Park, In Suk(1997) Originally the instruments were developed by Spreitzer(1995) and Jung Hea Joo(1998), who translated it into Korean. The data was analyzed using t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression. The results of this study were as follows : 1. Mean score of total empowerment was 3.76 and the subcategory 'meaning', had the highest score at 4.08. 2.Mean score of total health promoting lifestyle was 2.83 and in the subcategory, the highest degree of performance was 'sanitary life', followed by 'harmonious relationships' and 'self actualization'. The lowest degree was 'professional health management'. 3. A significant statistical difference between age, education and self-empowerment was found. 4. A significant statistical difference between age, marital status, leisure time activity (hobbies/community service) and a health promoting lifestyle was found. 5. Health promoting lifestyle was positively related to self-empowerment(r=.4592). A health promoting lifestyle was the highest positively related to the subcategory 'impact' (r=.4329). 6. The most important variable affecting the health promoting life style was impact which accounted for 19% of the total variance in stepwise multiple regression analysed. Five variables, impact, age, meaning, marital status and leisure time activity(hobbies/community service) accounted for 26% in promoting a healthy life style. From the results of the study, the following recommendations are presented : 1) Adopting the concept of self-empowerment is required in broad nursing fields. 2) Using and making a self-empowerment promoting program which can cause positive effects on a health promoting lifestyle are required. 3) It is required to check the rank of the subcategories such as meaning, competence, self determination and impact according to the subjects. 4) It is required to check the effects of all variances of self-empowerment, self-efficacy and self-esteem variances through the repeated studies.

This study was undertaken to provide correct posture guidance and reference material for sports injury and injury prevention programs, by analyzing body alignment and plantar pressure distribution in high school baseball players. Totally, 32 subjects were enrolled for the study. Body alignment was measured from the trunk imbalance, kyphotic angle, lordotic angle, pelvic tilt, and pelvic torsion. Foot pressure was measured from the left maximum pressure, right maximum pressure, left weight, and right weight. The mean and standard deviation of the measured factors were calculated and tabulated, and the correlation between body alignment and foot pressure distribution was analyzed using Pearson's correlation analysis. All statistical significance levels were set at 0.05. Body alignment and foot pressure distribution show a positive correlation between the lordotic angle of lumbar spine and the left maximum pressure. There was no correlation between trunk imbalance, kyphotic angle, lordotic angle, pelvic tilt, pelvic torsion, and the left·right weight distribution and the left·right maximum pressure of each foot. Results of this study determined that the increase of the lordotic angle of lumbar spine results in more force on one side of the foot, thereby increasing the maximum pressure. We believe our data could be a reference for exercise programs on physical alignment and plantar pressure distribution of athletes.
