Purpose : The purpose of this study was to examine the effect of rope-skipping exercise on body composition and basic physical fitness in healthy subjects: a randomized control trial. Method : Twenty two subjects were randomly allocated to two groups: rope-skipping group (n=11) and control group (n=11). The rope-skipping group participated in rope-skipping exercise for 30 minutes a day, three days a week for four weeks. Body composition was measured using the subjects' weight, body mass index (BMI), and waistline. Basic Physical fitness was measured flexibility and agility. Result : The rope-skipping showed significant differences in waistline and agility. The control group showed no significant differences. There were significant difference in agility between the rope-skipping and the control group. Conclusion : The rope-skipping exercise increased waistline and agility in healthy subjects. Additional research on rope-skipping exercise for improving body composition and basic physical fitness is need.

The Hiroshima Astrophysical Science Center (HASC) was founded in 2004 at Hiroshima University, Japan. The main mission of this institute is the observational study of various transient objects including gamma-ray bursts, supernovae, novae, cataclysmic variables, and active galactic nuclei by means of multi-wavelength observations. HASC consists of three divisions; the optical-infrared astronomy division, high-energy astronomy division, and theoretical astronomy division. HASC is operating the 1.5m optical-infrared telescope Kanata, which is dedicated to follow-up and monitoring observations of transient objects. The high-energy division is the key operation center for the Fermi gamma-ray space telescope. HASC and the high-energy astronomy group in the department of physical science at Hiroshima University are closely collaborating with each other to promote multi-wavelength time-domain astronomy. We report the recent activities of HASC and some science topics pursued by this multi-wavelength collaboration.

Purpose: This study examined the recognition of rehabilitative robots for treatment in physical therapists. Methods: This study surveyed 100 physical therapists in Seoul and Gyeonggi-do using Google Form, an online survey tool. The questionnaire consisted of 21 questions, including eight questions on the general characteristics, 13 questions on the recognition of rehabilitative robots. Results: The general characteristics of the physical therapists showed differences and influences on recognition of rehabilitative robots, and there were statistically significant differences. There were significant differences in the recognition of rehabilitation robots according to general characteristics in gender, age, education degree, type of hospital, average weekly working time, and treatment field. Multiple regression analysis found that gender and the type of hospital influenced the recognition of rehabilitation robots. Conclusion: Physical therapists showed differences in recognition of rehabilitative robots according to their general characteristics, and gender and the type of hospital influence the recognition of rehabilitation robots. Sufficient systematic education programs should be provided, and physical therapists require policy adjustments to increase their accessibility to rehabilitation robots through continuing education.

PURPOSE: This study compared the preferences of students majoring in physical therapy (PT) and those of physical therapists regarding various PT fields. METHODS: Two hundred and sixty-two participants (students: 161, physical therapists: 101) were recruited, and their preferences for seven fields of the PT (musculoskeletal system, nervous system, children and adolescents, cardiopulmonary system, sports, and pelvic and women's health) were surveyed using a Likert five-point scale. An independent t-test was conducted to compare the preference scores of each field between the PT student and physical therapist groups. RESULTS: PT for the musculoskeletal system was the most preferred by PT students and physical therapists. In contrast, PT for children and adolescents had the lowest preference. A comparison of the preferences of various PT fields in the two groups revealed PT students to have a significantly higher preference for PT on the musculoskeletal system, children and adolescents, and the nervous system compared with the physical therapists. CONCLUSION: These results could provide the basic information for various PT fields.

Purpose: This study sought to investigate the perceptions and service needs of tele-physical therapy among people in their 50s and older in Korea. Methods: Subjects were inducted during a 14-day survey of 104 people over the age of 50 in Korea and were administered a questionnaire consisting of 14 questions about their general characteristics and another 14 questions about tele-physical therapy. Results: The general characteristics of the participants (participants' gender, whether they were single or married, number of cohabiting families, final education, major, job, physical therapy experience, tele-physical therapy experience, presence of a physical therapy worker among relatives, subjective health awareness, chronic disease conditions if any, frequency of drinking, and smoking) were investigated. Among the perceptions of the subjects about tele-physical therapy, the score of 'awareness' was the lowest, and that of 'resolving restrictions on hospital visits' was the highest. In an analysis of the correlation between perceptions and needs, there was a significant correlation with factors other than 'awareness' and 'information protection' factors. The regression analysis of necessity and factors revealed that the awareness of necessity increased as the intention to use, health improvement, and time efficiency improved. Conclusion: These findings presented the perception and necessity of tele-physical therapy for adults in their 50s or older in Korea. These results will help confirm the demand for tele-physical therapy in this age group in Korea and the need to improve the available physical therapy services.

The relationship between symptoms of temoromandibular joint dysfunction(TMJD) and stomatognathic habit was studied in 500 adolescents(mean age 22.45). The severity of TMJD was determined by using a self-reported anamnestic questionnaire composed of 10 questions regarding common TMJD. The index of oromandibular habit was determined by using a self-reported anamnestic questionnaire composed of 17 questions. There was a positive correlation(p<0.01) between the index of TMJD and index of stomatognathic habit. The most frequent symptoms were clicking sounds from the TMJ(37.4%) and a feeling of pain in the jaws(33.3%). The most frequent stomatognathic habit were a chin support(69.8%) and one side chewing(68.0%).

Enhancing the capabilities of unmanned space exploration, such as satellite monitoring and space science missions, requires efficient and reliable nuclear power systems. A viable solution is found in the 1-10 kWe power level of space nuclear reactor power systems, offering advantages such as a manageable research and development process, and relatively low investment requirements. This paper introduces a conceptual design for a 5 kWe space nuclear reactor power system, outlining its components and characteristics. The study includes a thorough analysis of potential challenges, encompassing heat pipe failure accidents, re-entry scenarios, and weight estimation considerations. The results demonstrate that the proposed space nuclear reactor power system effectively meets the safety requirements. The total mass of the power system is estimated at approximately 1.5 tons, with a specific mass of around 300 kg/kWe. This research contributes valuable insights for the design of space nuclear reactor power systems operating within a similar power range.
