The purpose of this study was to analyze the recognition of secondary pre-physical education teachers' recognition for the learning athletics using Q methodology. P-sample was composed of 28 pre-secondary P·E teachers. The selected Q samples were arranged in the normal distribution form. The collected data were analyzed by factor analysis through varimax rotation using QUANL PC program. This study found four types of recognition on learning athletics. Type I is defined 'the type of recognition for education value.' Type II is defined 'the type of emphasizing assistant activities.' Type III is defined 'the type of an appeal difficulty to learn athletics skill.' Type IV is defined 'the type of emphasizing the basic movement value.' Based of the results of this study, the implications and direction to future research on athletics activities are suggested.

This study aims to examine the relationship between the expertise of track and field coaches, the team atmosphere, and athletic satisfaction in elite sports. To achieve this research purpose, data were collected using questionnaires from 221 student athletes from junior high to university students registered with the Korea Association of Athletics Federation in 2021 and collected using Google online questionnaires in consideration of the pandemic situation. For data processing, frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, and multiple regression analysis were performed using the statistical program SPSS 22.0, and the following conclusions were drawn. First, it was found that the expertise of the athletics coaches had a positive (+) effect on the team atmosphere. Second, among the sub-factors of athletics coach expertise, only athlete management was found to have a negative (-) effect on daily life satisfaction, a sub-factor of athletic satisfaction. Third, it was found that among the sub-factors of the team atmosphere, only role characteristics and leader characteristics had a positive (+) effect on social approval satisfaction, a sub-factor of athletic satisfaction.

복잡한 항만해역에서 자율운항선박 입출항 지원을 위해서는 항내에서 통항하는 선박에 대한 지속적인 인식이 필요하며, 이를 위해 선박자동식별시스템(AIS)에서 송출된 정보를 기반으로 선박의 운동정보(위치/침로/속도), 식별번호 및 크기 정보를 확인한다. 하지만, AIS 탑재 의무가 있는 선박에 대한 정보만 취득이 가능하기 때문에, 보조적으로 육상레이더를 활용하여 AIS 정보로부터 식별이 안되는 선박을 인식할 수 있는 기술이 필요하다. 본 연구에서는 자율운항선박 입출항 지원을 위해 레이더 이미지를 활용하여 선박의 운동정보와 형상정보를 동시에 추정할 수 있는 알고리즘을 설계하였다.

This study is to investigate the effect of Chinese university track and field athletes on their athletic commitment and performance. The men and women aged 19 or older were selected as a population for athletes from Hanam University, Jeongju University, and Hanam Normal University, and 1400 questionnaires were distributed using the Convenience sampling method. The results obtained by performing data processing are as follows. First, all factors had a statistically significant effect on performance in the effect of sub-factors of exercise commitment (cognitive commitment, behavioral commitment). Second, all factors had a statistically significant effect on the performance of the sub-factors of exercise commitment (cognitive commitment, behavioral commitment). Third, all factors had a statistically significant effect on the effect of sub-factors of exercise commitment (cognitive commitment, behavioral commitment) on concentration.

This study was carried out to investigate the self-reported health and eating habit of the elite female adolescent athletes in Incheon. The subjects were 102 elite female athletes of middle and high schools located in Inchon. A self-administered Questionnaire was used for this cross-sectional survey. Statistical analysis by two-way ANOVA was performed to discriminate between the main effects of age (as middle and high school athletes) and sports type, and their interaction. As use of nutritional supplements, 35.8% of the total subjects took vitamin and iron supplements and 62.5% of field and track athletes took vitamin and iron supplements. While mental stress related to exercise was much in fencing ＆gt; shooting ＆gt; field and track ＆gt; swimming athletes, physical burden during training was higher in swimming ＆gt; field and track ＆gt; fencing ＆gt; shooting athletes. More than half of the subjects showed irregular menstrual cycle. As the most severe problem of eating habit, they reported skipping meal ＆gt; overeating ＆gt; prejudiced meal ＆gt; preference to salty and spicy foods. More than half of the subjects skipped meal over three times per week. Fencing and shooting athletes showed very significantly higher frequency of skipping meal and more irregular breakfast time compared to those of other sport types. As for snack, they ate cookies, carbonated drink, chocolate, candy ＆gt; milk, yogurt, ice cream ＆gt; cake, bread, rice cake ＆gt; fried noodle ＆gt; hamburger, pizza. Therefore, nutritional counseling and education by sport type are necessary for health and good eating habit of these elite female adolescent athletes.

The purpose of the dissertation is to offer basic data available for being conducive to application of a training program by comparatively analyzing the players' physical strength, the knee joint, a hip joint, power of the trunk joint and muscle power in order to study isokinetic strength and muscle power between short distance athletes and Taekwondo players. This study measured peak power, %Body weight peak power, always power, and %Body weight peak power targeting 8 male athletes and 8 male Taekwondo players who warmed up 10 minutes before from the test to reduce repulsion and unfamiliarity at the instrument. The power of the knee joint($60^{\circ}$/sec), muscle power($180^{\circ}$/sec), were measured by using HUNOM(U.S.A). As a result of the physical strength, statistically, short distance athletes were indicated to be better in muscle strength, muscular endurance than Taekwondo players, and there was no significant difference between flexibility, power, and muscular endurance. Although the short distance athletes were indicated to be better in right and left muscle strength of knee joint than Taekwondo player, there was no significant difference and Taekwonde players were indicated to be higher at the right and left muscle power than short distance athletes.

In spite of the methodology of evacuation process on vessels should be different comparing to the architecture on land, some have simulated the evacuations onboard ship with simulation tools which is developed only for the architecture. On this study, a vessel-oriented simulation tool is used to analyze the possibility of evacuation for a passenger ship. ${\cdots}$(중략)${\cdots}$ As a result of the simulation analysis, it is clear that the initial responding time and start-to-move time are so important, ${\cdots}$(중략)${\cdots}$.

This study aimed to investigate the factors that influence the attitude toward doping and to provide useful information for developing a doping prevention program suitable for Korean athletic players. One hundred and seventy-two players who enrolled in Korea Association of Athletics Federations were participated in this study and they filled in the questionnaire about demographic factors, information on doping, perfectionism, and perceived motivational climate. Collected data were analyzed by using stepwise multiple linear regression for exploring the main factor that affect the attitude toward doping depending on field and track events. All adult players have more permissive attitude toward doping than adolescents. In track event, while players who are sensitive to coach's criticism have more permissive attitude toward doping, players who focused on personal standards have more repressive attitude toward it. These results would be useful to develop anti-doping strategy for Korean field and track players.

육상 환경과 인접해 있는 연안해양환경은, 그 변화 특성이 매우 독특하며 복잡하게 나타난다. 해양환경 변화에 큰 영향을 미치는 것 중에는 해류와 조류 등과 같은 유체의 운동의 역할이 크다. 특히 바람과 같은 기상환경인자는 해표면의 유체의 운동에 큰 영향을 주게 되며, 이로 인하여 유체내의 입자물질(적조생물, 유류 등)의 집적 및 확산에 결정적인 영향을 끼치게 된다. 우리 나라는 계절풍이 뚜렷하게 나타나는 지역이지만, 지역에 따라서는 주변 지역과의 기압배치 및 지형적인 요인등에 의해서 그 특성이 충분히 변할 수 있다. 이러한 지역적인 국지풍은 만과 같은 소규모 지역에서 큰 영향을 끼칠 것으로 생각된다.

세계적으로 수요가 증대하고 있는 고속선의 설계시 승선감 또는 내항성은 필수적으로 고려되어야 하는 중요요소이다. 고속선은 필연적으로 과도한 운동을 동반하며 그로 인해 승객들은 극심한 멀미와 구토 등 불쾌한 승선감을 경험하게 된다. 근래에 항공 및 육상 교통수단들의 고급화에 따라 해양 운항선사들도 선박품질의 고급화와 괘적한 승선감 확보에 비상한 관심을 보이며 승객 유치 및 승선률 제고를 도모하고 있다. 본 논문은 고속쌍동선에 대한 내항성능을 추정하고 그 해석결과를 실험과 비교하였다. 상하동요 및 종동요 간의 선형 연성 운동방정식을 사용하였고, 규칙파에 대한 상하동요의 응답특성 곡선을 구하였다. 또한 불규칙파에 대한 운동응답을 추정하기 위하여 ITTC파도 스펙트럼을 적용하였으며, 본 고속쌍동선의 운동성능에 미치는 선수 및 선수각의 영향을 고찰하였다.
