  • This study investigates supply patterns and residential characteristics of the Urban-type Housing in Seoul. There have been 3,336 buildings and 71,790 housing units approved until the end of 2012. One-room apartments and small units less than 30 $m^2$ of residential area amount to 81% and 82% of total units, respectively. Major findings are as follows. First, single- and two-person households less than 30 years of age are mostly lived in the housing. Respondents are mainly professional and white-collar (43%) and service and sales workers (27%). Most of them are mid-income classes (67%), which is twice more than that of single- and two-person households in Seoul. They pay 672 thousand won in rent more than average rent of mid-income class. The rent to income ratios are 29.9% for single households and 24.5% for two-person households, which are higher than that of mid-income bracket. Third, their satisfaction level is relatively high in internal environment and access to public service facilities, but not in external environment and community service facilities. They are satisfied with security and daylight, walking and safety, access to public transport and parking space, but not with noise and vibration, natural environment, access to park and cultural and sports facilities, and most community service facilities. It is necessary to reexamine the articles of deregulation and prepare design standards while considering different housing and locational types.

  • Soo-Yeoun Kim & Ji-Eun Kim 2016. A Study on ESP Skating English Education Based on Job Analysis. This study aims to provide skating ESP(English for Specific Purposes) education model for skating instructors in Korea. For this purpose, a total of twenty-seven professional skating instructors were surveyed according to a questionnaire, which asked about their English skills and perspective of the importance of English study and English skating class. The main results are as follows: most skating instructors' confidence in their English is low; majority of them answered that English study is needed for skating instructors; a majority of them want English teaching that focused on speaking and teaching activities. After that, skating instructors' jobs were analyzed using the DACUM(Developing A Curriculum Method). A DACUM committee extracted the duties and tasks which require English education and conducted a survey that targeted skating instructors. When interpreting the study on ESP Skating English Education based on job analysis, it was evident that the English language would be essential for enabling effective communication with judges during national sports competitions, information exchange with foreign skaters, and for technical skating instructions.

  • The game of Go, which is originated at least more than 2,500 years ago, is one of the oldest board games in the world. So far the theoretical studies concerning to the Go openings are still insufficient. We applied traditional LDA algorithm to recognize a pro player's opening to a class obtained from the training openings. Both class-independent LDA and class-dependent LDA methods are conducted with the Go game records of the Korean top 10 professional Go players. Experimental result shows that the average recognition rate of class-independent LDA is 14% and class-dependent LDA 12%, respectively. Our research result also shows that in contrary to our common sense the algorithm based on PCA outperforms the algorithm based on LDA and reveals the new fact that the Euclidean distance metric method rarely does not inferior to LDA.

  • Taekwondo has developed into a global sport that sports 80 million people from 208 countries around the world. Korea is the mother country of Taekwondo, and there are many international Taekwondo events in Korea. As important as the image of Taekwondo contents, it will be operation plan and management for event facilities. In particular, safety management for participants is more important than anything else. In case of Taekwondo where there are many national events, there are many foreign visitors, so safety management in facilities and running programs needs to be important. In this study, we conducted in - depth interviews with experts with a career in Taekwondo events. Based on the in - depth interviews, we analyzed the safety management problems of the international Taekwondo events and suggested improvement directions to overcome them. Based on the results of these researches, the improvement direction of Taekwondo event safety management proposed in the first category is a demand for improving safety and injury related system construction. The second category, the safety improvement of visitors, is to secure professional manpower and secure budgets. Also, what is important in the third category, facility safety area, is the proposal to introduce facility safety certification system.

  • This study evaluated soccer-specific fitness early and late season to check the conditioning status of K3 league soccer players. Evaluation factors included body composition, agility, quickness, endurance and isokinetic limb muscle strength. As a result, the factors that showed improvement in the late season were skeletal muscle mass, agility and quickness, and body composition, endurance and isokinetic limb muscle strength were not different from each other. The factors that showed improvement in the second half of the season are thought to be due to the learning effect of repetitive training, competition participation during the season. Lastly, endurance and lower extremity strength did not show improvement in the second half of the season due to the fact that no specific training was performed during the season. Taken together, it is necessary to periodically check the fitness status of athletes to develop and apply a fitness training program suitable for competition, transition and preparation period.

  • The purpose of this study is basic data for developing baseball uniform in the future by carrying out a survey of amateur baseball players on the wearing pattern of uniform and inconvenient details. To do this study, a survey targeting 307 male social baseball players in their 20s to 40s was conducted, and a preliminary survey through interview with designers, MDs and patternmakers had also been carried out and analyzed prior to the main one. The result shows that armpit and back patches get wet with perspiration the most, and patches around knees are likely to be worn out because of frequent sliding. Thus, they are dissatisfied with poor protective function the most and need quilted pads around knees. Answers for a question on injuries during games indicates that shoulder injuries due to pitching or batting and abrasion owing to sliding are most common and knee injuries are also frequent. As for the wearing satisfaction of uniform, they want elasticity and breathability of textile to be improved; they are not satisfied with its design and fit because they think top and bottoms are much too long and uncomfortable; they often find dirt inside of the uniform during games. Besides, they find it very difficult to remove dirt from the uniform even after washing. There has been a growing population of amateur baseball players over recent years, so this study would help develop functionally improved uniform and be used for developing uniform for professional baseball players.

  • Aggression in horses may cause serious accidents during riding and non-riding activities. Hence, predicting the temperament of horses is essential for selecting suitable horses and ensuring safety during the activity. In certain animals, such as hamsters, plasma melatonin concentrations have been correlated with aggressive behavior. However, whether this relationship applies to horses remains unclear. To address this research gap, this study aimed to evaluate differences in the plasma melatonin concentrations among horses of different breeds, ages, and sexes and examine the correlation between plasma melatonin concentrations and the temperament of the horses, including docility, affinity, dominance, and trainability. Blood samples from 32 horses were collected from the Horse Industry Complex Center of Jeonju Kijeon College. The docility, affinity, dominance, and trainability of the horses were assessed by three professional trainers who were well-acquainted with the horses. Plasma melatonin concentrations were measured using an enzyme-linked immunosorbent assay. The consequent values were compared between the horses of different breeds, ages, and sexes using a three-way analysis of variance and least significant difference post hoc test. Linear regression analysis was employed to identify the relationship between plasma melatonin concentrations and docility, affinity, dominance, and trainability. The results showed that the plasma melatonin concentrations significantly differed with breeds in Thoroughbred and cold-blooded horses. However, there were no differences in the plasma melatonin concentrations between the horse ages and sexes. Furthermore, plasma melatonin concentrations did not exhibit a significant correlation with the ranking of docility, affinity, dominance, and trainability.

  • Baseball attracts the largest audience among professional sports in Korea. In particular, attendance is the primary source of income in baseball. Previous studies have limitations in reflecting the characteristics of individual stadium. For instance, the KIA Tigers exhibit the highest away game revenue among domestic teams, but they show lower home game earnings. Therefore, we aim to predict the daily attendance at the Gwangju-KIA Champions Field of the KIA Tigers using deep learning. We collected and preprocessed daily attendance, dates, weather, and team-related variables for Gwangju-KIA Champions Field from 2018 to 2023. We propose a deep learning-based linear regression model to predict the daily attendance. We expect that the proposed deep learning model will be used as basic information to increase the club's revenue.

  • Purpose: The purpose of this study was to evaluate the mechanism of injury in the anterior cruciate ligament tears sustained in participation in soccer. Materials and methods: 50 patients whose knees were injured during playing soccer were enrolled in this study. The mean age was 27 years old, 47 were male and 3 female. 15 of them were either professional or amateur soccer players, the rest were non-professional. The injury mechanism was investigated by evaluation of the medical records or by telephone interview. Results: The injury mechanism involved contact injuries in 17 patients and non-contact in 33. 41 patients were bearing weight on the involved side at the time of injury, and 9 patients were not. In cases of contact injury, 9 of the 17 patients had sustained a valgus force to the knee, and 5 patients had varus force, 11 patients had their foot planted, and 6 did not. Among those patients with a planted foot, 3 patients were injured by the rotation of the thigh, 1 patient was injured by hyperextension, and there were no deceleration mechanism injuries. In non-contact injuries, 30 out of 33 patients had their foot planted at time of injury and only 3 patients did not. Of these 30 patients, 16 were injured by the rotation of thigh, 6 sustained a varus force on the knee joint and 5 had a valgus force, 5 were injured by hyperextension, and 2 by deceleration. 3 patients, who did not have their foot planted, were injured while kicking with the involved leg. Conclusions: For soccer players in this series, the most common mechanisms resulting in anterior cruciate ligament tears were non-contact, most often by rotation of the torso over a planted foot. In contact injuries, the most common mechanism was the application of valgus force by tackle.
