This descriptive study looks into the levels of BMI, dietary habits, body image, and eating attitudes which have a major impact on the obesity management of female college students. A total of 173 female college students from the same school participated in this study by filling out a self-administered questionnaire investigating actual conditions. The average age of the participants was 19.5 years old and the average BMI was $21.8kg/m^2$. There were statistically significant differences in dietary habit at home (t=2.957, p=.004), eating attitudes BMI (F=5.324, p=.006), actual body image within perceived body esteem and BMI (F=36.979, p=.000), level of state body esteem BMI (F=11.539, p=.000), level of eating attitudes BMI(F=5.324, p=.006). Among the relationships between variables, the higher the BMI, the higher the score for perceived body esteem and problems concerning eating attitudes became prevalent. The higher the actual body image score, the lower the state body esteem and problems concerning eating attitudes became prevalent. Therefore, there is a need for education that enhances positive body image and eating attitudes in order for female college students to manage obesity due to dietary habits.

The accuracy and reliability of the target tracking is very critical issue in the design of automotive collision warning radar A significant problem in multi-target tracking (MTT) is the target-to-measurement data association If an incorrect measurement is associated with a target, the target could diverge the track and be prematurely terminated or cause other targets to also diverge the track. Most methods for target-to-measurement data association tend to coalesce neighboring targets Therefore, many algorithms have been developed to solve this data association problem. In this paper, a new multi-target data association method based on order statistics is described The new approaches. called the order statistics probabilistic data association (OSPDA) and the order statistics joint probabilistic data association (OSJPDA), are formulated using the association probabilities of the probabilistic data association (PDA) and the joint probabilistic data association (JPDA) filters, respectively Using the decision logic. an optimal or near optimal target-to-measurement data association is made A computer simulation of the proposed method in a heavy cluttered condition is given, including a comparison With the nearest-neighbor CNN). the PDA, and the JPDA filters, Simulation results show that the performances of the OSPDA filter and the OSJPDA filter are superior to those of the PDA filter and the JPDA filter in terms of tracking accuracy about 18% and 19%, respectively In addition, the proposed method is implemented using a developed digital signal processing (DSP) board which can be interfaced with the engine control unit (ECU) of car engine and with the d?xer through the controller area network (CAN)

The purpose of this study was to explore the effects of science classes on positive science experiences and science learner identity, using smart devices in a future school: C middle school. We conducted a paired t test at the beginning and end of the first school year with first-grade students at the future school to investigate positive experiences with science (Shin et al., 2017). Additionally, first and second-grade students in future schools using smart devices wrote and drew their own depictions in science classes to explore science learner identity, based on a modified analytical framework (Luehmann, 2009). The results show that significant effects on science-related career aspirations, self-concepts, and academic emotions were produced by science classes using smart devices. Science classes using smart devices helped students improve their level of agency and activity, solve problems with immediate and sufficient feedback, and experience meaningful perceptions of the nature of science. On the other hand, if students were immature in terms of their use of smart devices, they felt pressured to participate in the classes. The results of this study can be used as a foundation for designing various classroom contexts for the use of smart devices.
