Central Bank authorities should carefully manage inflation rate uncertainties to achieve economic growth and development not only in the short-run but also in the long-run. Since inflation is a key macroeconomic variable, an increased understanding about its behavior is undoubtedly important. Thus, paper employs unit root with breakpoints to examine the mean reverting behavior of inflation rate in the Philippines using monthly data from 2002 to 2020. Empirically, the unit root breakpoint innovational and additive outlier tests favor the stationarity or mean reverting behavior of inflation in the Philippines. Also, results of standard unit root tests, ADF, PP, GLS-Dickey-Fuller, KPSS and NP, provide strong evidence of mean reverting processes. The mean reverting behavior of inflation rate reveals that the monetary policy using inflation targeting framework has succeeded in reducing chronic inflation persistence in the Philippines. Thus, this research supports inflation targeting policy that aims to maintain general price level stability for the Philippine economy's long-term growth and development prospects. The findings of this research remain important for the central bankers for not only providing them better understanding about the behavior of inflation rate, but also helping them formulate and implement policy reforms related to money, credit and banking.

Design/Methodology/Approach First, a preliminary study was conducted with targeting seniors who have visited Gwangju Senior Technology Center(GSTC) in order to understand the factors that affect the intention of utilizing smartphones. Next, based on the preliminary study results and literature reviews including the UTAUT model, performance expectancy, effort expectancy and social influence were considered for the major factors affecting the usage of elderly people's smartphones. Also, the moderate effects of personal innovativeness and usage function were discussed. A questionnaire survey of 181 seniors visiting GSTC was analyzed to empirically test the research model. Findings By the empirical tests, the performance expectancy and the effort expectancy of the seniors had significant impacts on their smartphone usage behavior. While the moderating effect of personal innovativeness was not significant, the moderating effect of the usage function was significant in the relationship between performance expectancy and the smartphone usage behavior. The results of this study are expected to provide guidelines to excavate the technical development and the niche market targeting the elderly people.

The purpose of this study was to set up an effective marketing strategy targeting college women by researching the relationship between weight control behavior and body exposure in clothing behavior. The results showed that 1) 85.5% of the college women participated in weight control behavior, and 53.5% of them wanted to lose more than 3kg of their weight. 2) College women were less satisfied with their body and thar showed less body exposure in clothing behavior according to the increase of weight control degree. The weight control parts and unsatisfied body parts were almost matched : thigh, abdomen, hip, calf, and weight. College women preferred clothing that exposed neck, legs and shoulder more than clothing that exposed many parts of their body at the same time. 3) exposure in clothing decreased according to the increase of weight control degree, except for the exposure of breast in clothing.

Purpose: This study was conducted in order to closely examine the effects on bone mineral density and health promotion behaviors following the intervention of a 20-week Thera band exercise program targeting elderly women. Methods: This study is a pseudo-experimental research with a pre-and-post design in a single group that examined the effects after the intervention of Thera Band Exercise for 20 weeks targeting 31 elderly women over 60 years of age who visit a Senior Welfare Center located in K city. It analyzed subjects' general characteristics using error and percentage, health promotion behavior, and a bone density aspect using the mean and standard deviation, as well as a change in the health promotion behavior and bone density, before and after exercise with Paired t-test by using the SPSS 18.0 program. Results: The effect of the Thera band exercise program on bone mineral density was reduced (t=8.140, p<.001) gradually after 20 weeks of exercise compared to the pre-exercise period. The health promotion behavior before and after exercise showed the significantly increasing outcomes (t=3.26, p=.003). Conclusion: There is a limitation to a direct rise in bone mineral density with the use of Thera band exercise intervention in the elderly. A change in health promotion behavior before and after exercise increased significantly. Thus, it was confirmed that taking exercise leads to a gradual rise in health promotion behavior. Hence, it understood that continuous exercise is useful and brings about a positive change in promoting health maintenance in elderly women.

Natural killer (NK) cells play a crucial role in combating infections and tumors. However, their therapeutic application in solid tumors is hindered by challenges, such as limited lifespan, tumor penetration, and delivery precision. Our research introduces a novel ultrasonic actuation technique to navigate NK cells more effectively in the vascular system, particularly at vessel bifurcations where targeted delivery is most problematic. We use a hemispherical ultrasonic transducer array that generates phase-modulated traveling waves, focusing on an ultrasound beam to steer NK cells using blood-flow dynamics and a focused acoustic field. This method enables the precise obstruction of non-target vessels and efficiently directs NK cells toward the tumor site. The simulation results offer insights into the behavior of NK cells under various conditions of cell size, radiation pressure, and fluid velocity, which inform the optimization of their trajectories and increase targeting efficiency. The experimental results demonstrate the feasibility of this ultrasonic approach for enhancing NK cell targeting, suggesting a potential leap forward in solid tumor immunotherapy. This study represents a significant step in NK cell therapeutic strategies, offering a viable solution to the existing limitations and promising enhancement of the efficacy of cancer treatments.

By targeting 113 gifted underachievers and 128 gifted achievers from 17 elementary schools, this study examines the home variables that affect gifted children's underachievement. In an effort to determine home variables of gifted achievers and underachievers, their homes' socio-economic status was analyzed and their parental child-rearing behavior was examined. First, the home environments of the gifted achievers and underachievers were compared, with the finding that their homes' socio-economic status, parental child-rearing behavior and other home factors differed. Parents of gifted achievers raised their children in a rational and democratic manner, while those of gifted underachievers tended to raise their children in an irrational and authoritarian manner. Second, discrimination analysis was conducted using home variables that showed a statistically significant difference, indicating that their homes' socio-economic status showed a low discrimination compared with their parental child-rearing behavior. Likewise, among the family factors, active involvement had the greatest effect on the underachievement of gifted children.
