본 연구는 초등학생의 역량에 대한 평가유형과 공격성이 어떤 관계가 있는지 밝히고자 한다. 평가유형을 과대평가와 과소평가로 구분하였으며 역량에 대한 평가 유형과 성별을 독립변수로, 공격성을 종속변수로 설정하였다. SPPC, TRS, 그리고 AS 척도를 419명의 학생들과 20명의 교사들에게 실시하였다. 본 연구의 결과는 다음과 같다. 첫째, 역량에 대한 자기-교사 평가 간의 상관은 학업능력이 가장 높았다. 둘째, 과소평가 빈도는 행동 품행에서 가장 높았다. 셋째, 행동적 공격성에서 성별에 따른 차이가 나타났다. 그리고 운동능력을 과소평가할 때, 행동적 공격성이 높았다. 넷째, 신체 용모를 과소평가할 때, 공격성의 모든 하위영역인 행동적 공격성, 적대감, 분노감이 높게 나타났다. 다섯째, 적대감에서는 성별과 행동 품행 평가유형 간의 상호작용효과에서 유의미한 차이가 나타났다. 위의 결과는 역량에 대한 평가유형이 항상 공격성을 초래하는 것은 아님을 의미하며 초등학생의 공격성 감소를 위한 유용한 기초 자료가 될 것이다.

PURPOSE: This study examined the effects of muscle fatigue on proprioception in the type of taekwondo training, causing injury to taekwondo athletes. METHODS: The subjects were divided into Taekwondo Kyorugi athletes (n = 14) and Taekwondo Poomsae athletes (n = 14). After inducing muscle fatigue to the subjects, the joint position sense (JPS) and the force reproduction sense (FRS) were measured before and immediately after the induction of muscle fatigue. RESULTS: Studies have shown no significant impact on the JPS and FRS caused by muscle fatigue induced by Poomsae and Kyorugi (p > .05). The JPS, however, showed a significant difference before and after Kyorugi (p < .05). The FRS showed significant differences before and after Poomsae (p < .05). Through this study, the injuries to taekwondo athletes appear to be influenced by the joint position and force reproduction. Moreover, the injury appears to affect the joint position sense in Kyorugi athletes and the force reproduction sense in Poomsae athletes. CONCLUSION: The results will contribute to injury prevention and athlete protection. In addition, the information can be used as basic data for the development of sports injuries prevention and rehabilitation programs for Taekwondo athletes. Research is needed on the customized management of sports methods and self-care to prevent sports damage, considering the athletic characteristics of the taekwondo athletes in the future.

This study aimed to produce sensors for measuring thigh motor skills. A textile stretch sensor was manufactured using a CNT(Carbon Nano Tube) 0.1 wt% water SWCNT(Single-Walled Carbon Nano Tube) solution, and different designs were applied to increase the sensitivity of the sensor, and different GF(Gauge Factor) values were compared using UTM devices. The same design was applied to fabrics and weaves to observe changes in performance according to fibrous tissue, and the suitability of sensors was determined based on tensile strength, elongation, and the elongation recovery rate. Sensitivity was found to vary depending upon the design. Thus the manufactured sensor was attached to a pair of fitness pants as a prototype, divided into lunge position and squat position testing, and the stretch sensor was used to measure thigh movements. It was shown that stretch sensors used to measure thigh motor skills should have light and flexible features and that elongation recovery rates and tensile strength should be considered together. The manufactured stretch sensor may be applicable to various sports fields that use lower limb muscles, wearable healthcare products, and medical products for measuring athletic ability.

The purpose of this study is to interpret the semantic actions of body image symbolized in body expression images shown by micro-influencers body profiles to understand the body profile phenomenon of the MZ generation. As a result of collecting body profile data from micro-influencers, the body profile image types of female influencers on SNS were classified into four types, Athletic, Slim body, Natural, and, Glamorous. Images representing each type were analyzed using the Roland Barthes' Myth model analysis frame. As a result of the semantic analysis, influencers were found to be very active and bold, emphasizing certain body parts according to the type of body image they pursue. Fashion is strategically used to emphasize these aspects. It was found that the ideology of a 'subjective modern woman' was commonly expressed through emphasis on visual signs. This study is meaningful in that it can indirectly lead to the understanding the fashion culture expressed by the MZ generation and provide consumer information and essential data that can be used for communication strategies in the fashion market.

People have recently became interested in eco-friendly cycling that attracted further attention as a sport activity. The number of high school cyclists has increased due to the popularity of cycling; however, high school cyclists have trouble choosing cycling suits because there is no professional cycling suit for high school cyclists in Korea. Therefore, it is necessary to develop a professional cycling suit for high school cyclists because sportswear for athletes is an important means to improve performance. This study suggests a standard sizing system for high school student athletes' cycle tights. The subjects were 111 high school cyclists. The 3 clusters were categorized by cluster analysis, and the sizing system was classified according to three lower body types. The size intervals of waist girth, hip girth and height were 5cm, respectively. The most frequent sizes were 75-100-175 in figure type 1, 70-90-170 and 75-95-170 in figure type 2, 70-90-175 and 70-90-180 in figure type 3. The sizing system, which had frequencies more than 3.6%, was classified into 9 cases, 8 cases, and 5 cases, respectively by lower body types. The results will contribute to the development of athletic performance cycle wear for high school cyclists.

The purpose of this research is to understand the physiological characteristics of muscular men between the ages of 20 and 34 years who are distinct from the general population due to their muscular development, and to categorize them according to upper body somatotypes. This research was conducted in order to provide basic data necessary for developing clothing products for muscular men. The research method and results were as follows: the "Sheldon's" and "Heath-Carter" somatotype classification methods were carried out at sports centers, the Athletic College, and military bases in Seoul and Gyeonggi province. Excluding the 32 subjects that did not have a balanced mesomorph, ectomorphic mesomorph or mesomorph-ectomorph, research on the remaining 168 subjects was used in the data analysis. 2. We used the following factor analysis: factor 1 for torso size; factor 2 for upper-arm, armpit, and chest breath size; and 3. The upper body was categorized into four (4) types, and their individual characteristics were as follows: Type 1 had the most developed arms, shoulders, chest muscles, and the shortest height. These subjects had an average of 191 somatotype points and could be classified as a balanced mesomorph. The heights and the lengths of Type 2 were short. They had slim physical structures, averaged 182 somatype points, and could be classified as an ectomorphic mesomorph. somatotype points and were classified as a balanced mesomorph. The heights and the lengths of Type 4 were long. They had slim physical structures, averaged 164 somatotype points, and were classified as a balanced mesomorph-ectomorph. 4. After carrying out a discriminant analysis to validate the categories of muscular men's upper bodies, we concluded that our model had an accuracy rating of 98.1%.

This study investigates coping strategies of overweight or underweight males in Korea. For this purpose, the authors identify types of stress related to weight management. A qualitative method was utilized to collect the data related to successful weight management experiences of males aged 20-37 years. Data were analyzed based on a motivation theory of coping, which suggests coping strategy elements. The results of this study identified the stress related to weight: dissatisfaction with appearance, others' disapproval of appearance, health problems, weaker athletic ability, negative self-perception, passiveness about appearance, lower romantic attractiveness, others' disapproval of lower romantic attractiveness, weakened task execution capability, and negative stereo-types about task execution capability. In addition, six coping strategies were suggested: improved appearance, improved physical function, improved positive self-perception, more choices to improve appearance, enhanced romantic relationship, and enhanced job performance. This study shows that weight problems in modern society are diverse and complex. Therefore a man who has abnormal weight needs to clarify his stress first and then proposes strategies that are appropriate for each type of stress.
