본 연구는 전북지역 J지역의 65세이상 노인여성들의 운동프로그램 구성에 있어 타당성과 운동에 대한 효과성을 살펴보고자 12주간 매트운동프로그램 운동이 노인여성들의 신체구성과 행동체력에 미치는 효과를 알아보기 위하여 실시하였다. 이를 위해 12주간 주 3회 1일 60분 실시하였으며, 준비운동 10분, 본 운동 40분, 정리운동 10분으로 진행하였으며, 사전·사후로 신체구성 및 행동체력을 측정하여 비교분석 하였다. 본 연구에서 매트운동이 노인여성의 신체구성 및 행동체력의 변화를 확인하고 각 변인들의 얻어진 결과를 바탕으로 다음과 같은 결론을 얻었다. 첫쨰, 신체구성의 변화에서 체중, 골격근량은 통계적으로 유의한 차이를 보였으며(p<.01), 체지방량, 체지방률, 복부지방률에서 평균값은 감소하였지만 통계적인 유의한 차이를 보이지 않았다. 둘째, 행동체력의 변화에서 근지구력(p<.05), 정적평형성(p<.01), 동적평형성(p<.001)은 통계적으로 유의한 차이를 보였으며, 근력, 유연성은 평균값의 증가는 있었지만 유의한 차이를 보이지 않았다. 심폐지구력은 운동 후 다소 감소하였지만 통계적으로 유의한 차이는 없었다. 이상의 결과를 종합해 볼 때, 본 연구에서 적용한 12주간의 매트운동프로그램이 노인여성의 신체구성 및 행동체력은 일부 증가 또는 감소하였지만 지속적인 운동을 통해 신체조성 및 행동체력에 긍정적인 효과를 가져올 것이다. The purpose of this study is to investigate the validity and effectiveness of exercise programs for elderly women aged 65 years and over in J-region in Jeonbuk region. To investigate the effects of 12-weeks mat exercise program exercise on body composition and behavioral strength of elderly women. It was done for. To this end, it was conducted three times a week for 12 weeks, 60 minutes a day, 10 minutes of warm-up exercise, 40 minutes of main exercise, 10 minutes of cleanup exercise, and comparative analysis was conducted by measuring body composition and physical strength before and after. In this study, mat exercise confirmed changes in body composition and behavioral stamina of elderly women, and the following conclusions were drawn based on the obtained results of each variable. First, there was a statistically significant difference in body weight and skeletal muscle mass in the change of body composition (p<.01), and the average values in body fat mass, body fat percentage, and abdominal fat percentage decreased, but there was no statistically significant difference. Second, there were statistically significant differences in muscle endurance (p<.05), static equilibrium (p<.01), and dynamic equilibrium (p<.001) in the change of behavioral fitness, and muscle strength and flexibility increased the average value. There was, but there was no significant difference. Cardiopulmonary endurance slightly decreased after exercise, but there was no statistically significant difference. In summarizing the above results, the 12-week mat exercise program applied in this study partially increased or decreased the body composition and behavioral stamina of elderly women, but it will have a positive effect on body composition and behavioral stamina through continuous exercise.

Granulosa cell tumors of the ovary are rare, and account for 2 to 3% of ovarian tumors. Granulosa cell tumors are discovered often in perimenopausal or postmenopausal women but 10 to 26% are found in the reproductive age group. The tumors associated with pregnancy are infrequent. In this study, we present a case of granulosa cell tumor of left ovary at pregnancy

The purpose of this study was to investigate the relationship between mentoring of bowling leaders and self-management and performance strategies.The subjects of this study were middle school, college, and unemployed teams, and a total of 300 samples were collected. A total of 279 copies were selected for the final survey, except for 21 copies of the questionnaire which were considered inconsistent or incomplete. Survey tools used revised and supplemented questionnaires from previous studies, and researchers visited and collected data directly. Data processing was performed using correlation analysis and multiple regression analysis according to research hypotheses using SPSS 23.0 program, a statistical processing program. The results are as follows. First, bowling mentor mentoring has partially affected self-management. Second, bowling mentor mentoring in part affected the performance strategy. Third, self - management influenced the quality of performance strategies. Through this study, it is possible to provide basic data that can form a positive tie between the bowling player and the leader and to create an environment in which the players can concentrate.

KSR-Ⅲ 로켓은 액체추진 엔진을 사용한 과학로켓이며, 추력 비행중 피치 및 요 자세제어를 위해 추력벡터제어 방식을 사용하고, 롤 자세를 제어하기 위해 냉가스 추력기를 사용하였다. 본 논문은 KSR-Ⅲ 로켓의 3축 자세제어를 위해 설계된 자세제어기의 구조와 이득 스케쥴링, 자세 안정성 분석결과에 대해 소개한다. 설계된 자세제어기는 국산화 개발된 관성 항법시스템의 비행소프트웨어로 구현되었는데 비행시험에서 완벽히 작동하였다. 비행에서 측정된 데이터는 시뮬레이션 결과와 거의 일치되었다. The KSR-Ⅲ rocket is a liquid propellant sounding rocket and thrust vector control actuators and cold gas thrusters are used to control pitch and yaw, roll attitude respectively during thrusting phase. In this paper, the structure of designed attitude controller and gain scheduling, results of stability analysis for KSR-Ⅲ rocket are presented. The attitude controller is implemented with flight software in the domestically developed INS and successfully performed its function in the flight test. The flight data are coincident with simulation results.

Trisomy 22 is a frequent finding in spontaneous abortion. However, survival to term is tenuous. So far there have been about 85 cases of trisomy 22. Most of all cases, trisomy 22 was result of 3:1 meiotic segregation in the maternal 11;22 translocation carrier. These patients have a supernumerary, abnormal chromosome 22 [der(22)], in their chromosome constitution: 47, XX(or XY),+der(22),t(11q;22q). Affected children have a distinct phenotype with multiple anomalies and severe mental retardation. We now report a viable case of 47,XX,+der(22)t(11;22)(q25;q13.1) resulting from 3:1 segregation in paternal translocation.
