The current study examined college students' overall eating behavior and physical activity, highlighting differences between male and female students attending a public university in the southwestern United States. Research findings indicated that many college students did not eat enough fruits, fruit juices, and green salad. Furthermore, the results of Chi-square analysis showed that there were significant differences in consumption amounts of green salad, hamburgers/hot dogs/sausage, and French fries/potato chips between male and female students. Study findings showed that when students were asked about attributes of food/restaurant choice, female students were more concerned about nutritional aspects when they chose the foods compared with male students. In terms of physical activity levels among college students, male students were more likely to participate in sports activities and weight training. On the other hand, female students were more inclined to walking or bicycling.

Similar to present computers, quantum computers comprise quantum bits (qubits) and an operating system. However, because the quantum states are fragile, we need to correct quantum errors using entangled physical qubits with quantum error correction (QEC) codes. The combination of entangled physical qubits with a QEC protocol and its computational model are called a logical qubit and fault-tolerant quantum computation, respectively. Thus, QEC is the heart of fault-tolerant quantum computing and overcomes the limitations of noisy intermediate-scale quantum computing. Therefore, in this study, we briefly survey the status of QEC codes and the physical implementation of logical qubit over various qubit technologies. In summary, we emphasize 1) the error threshold value of a quantum system depends on the configurations and 2) therefore, we cannot set only any specific theoretical and/or physical experiment suggestion.

We discuss why many current physical therapy entry-level programs are not designed to educate the type of physical therapy practitioners needed for the 21st century. We face a situation that we have to promote the profession's role in the prevention, diagnosis, and treatment of movement dysfunctions and the enhancement of the physical health and functional abilities of members of the public. The way how to train professional physical therapists became crucial. The purpose of study was to enhance the educational goals of physical therapy and the physical therapy curricula in Korea. In this study, we compared physical therapy training curricula recommended by WCPT with physical therapy training curricula in universities in other countries by dividing physical therapy curricula in universities and colleges into physical therapy students' electives, major required courses, labs and clinical practices, and counting the proportion of each category in the total credit hours. We discuss differences and similarities between curriculum in a university in Korea and curriculum in a university in the United States. We discussed possibly problematic portions of current physical therapy training curricula in korean universities. Finally, we statistically analyzed the regulations of WCPT and Health and Welfare Ministry in Japan, the Physical therapy curriculum of Creighton Entry-level DPT Program in the U.S. and the Inje University in Korea. The progressing direction of curricula in Korea had been researched. The future direction that korean physical therapy is to use an united curriculum that includes basic requirements of WCPT for all universities and colleges in Korea, rather than using each university's own modified version. The results of study can be helpful for developing a basic level of integrated curricula in universities and colleges in Korea.

The aim of this study to present useful information on effective space composition by understanding education process of a preschool for children's education and required interior space for this process. The 6th education process of a preschool as the criteria on this study would be classified into 5 spheres as follows : Health life, Social life, Expression life, Language life. survey life. And the required interior space would largely be classified into interesting sphere and home sphere. As a result of analyzing the space composition, we can draw conclusion as follows : First, the interior spaces for properly doing children's education process have close relations. So, each sphere too independent or too unified is not good. That is to say, each sphere has closely organic connection for enhancing efficiency. Secondly, children's service spaces are considered to in children's education process. And the space had better be made for children only considering their physical states. Finally, we have to in advance process. And the space had better be made for children only considering their physical states. Finally, we have to in advance understand educational aim and program because space composition can be changed according to the aim of education process.

Vortex lock-on or resonance in the flow behind a circular cylinder is visualized by a time-resolved PIV when a single frequency oscillation is superimposed on the mean incident velocity. Measurements are made of the $K{\'{a}}rm{\'{a}}n$ vortices in the wake-transition regime at the Reynolds number 360. Basically, natural shedding state is observed to compare with lock-on state. Wake motion by the change of the shedding frequency of lock-on state is investigated. When lock-on occurs, the vortex shedding frequency is found to be half the oscillation frequency as expected from previous experiments. The physical flow phenomena of natural shedding and lock-on states are analyzed with physical parameters of recirculation and vortex formation region. Consequently, it is found that the change of wake bubble plays an important role in the flow at the lock-on state. Vortex formation region is also actively changed like recirculation region as the lock-on occurs. Therefore, it is deduced that the recirculation region is closely related with the vortex formation region.

Vital area identification (VAI) is an essential procedure for the design of physical protection systems (PPSs) for nuclear power plants (NPPs). The purpose of PPS design is to protect vital areas. VAI has been improved continuously to overcome the shortcomings of previous VAI generations. In first-generation VAI, a sabotage fault tree was developed directly without reusing probabilistic safety assessment (PSA) results or information. In second-generation VAI, VAI model was constructed from all PSA event trees and fault trees. While in third-generation VAI, it was developed from the simplified PSA event trees and fault trees. While VAIs have been performed for NPPs in full-power operations, VAI for NPPs in low-power and shutdown (LPSD) operations has not been studied and performed, even though NPPs in LPSD operations are very vulnerable to sabotage due to the very crowded nature of NPP maintenance. This study is the first to research and apply VAI to LPSD operation of NPP. Here, the third-generation VAI method for full-power operation of NPP was adapted to the VAI of LPSD operation. In this study, LPSD VAI for a few plant operational states (POSs) was performed. Furthermore, the operation strategy of vital areas for both full-power and LPSD operations was discussed. The LPSD VAI method discussed in this paper can be easily applied to all POSs. The method and insights in this study can be important for future LPSD VAI that reflects various LPSD operational states. Regulatory bodies and electric utilities can take advantage of this LPSD VAI method.

In this paper, we introduce our system for manufacturing a Rb vapor cell and describe its fabrication process in a sequence of removing impurities, cold trapping, and sealing off. Saturated absorption spectroscopy was performed to verify the quality of our cell by comparing it to that of a commercial one. By using the lab-fabricated Rb vapor cell, we observed electromagnetically induced transparency in a ladder-type system corresponding to the 5S_1/2-5P_3/2-28D_5/2 transition of the ⁸⁵Rb atom. A highly excited Rydberg atomic system was prepared using two counter-propagating external cavity diode lasers with wavelengths of 780 nm and 480 nm. We also observed the Autler-Townes splitting signal while a radio-frequency source around 100 GHz incidents into the Rydberg atomic medium.
