Risky health behaviors and behavioral differences of the US youth: quasi-evidence with empirical study: policy implications
No full textThe focus of this paper is to examine the determinants and analyze the effects of risky health behaviors of alcohol and illicit drug use on social violence (drunken driving, riding in a car driven by a drunken driver, and not wearing seatbelts) among youth in the United States. Alcohol and illicit drug use usually lead to social violence as well as a reduction in health status and earnings. Although it is illegal to drink and drive in the U.S., forty-five percent of the traffic accidents among the age group of 14-18 are alcohol-related. Alcohol is a leading factor in deaths related to motor vehicle accidents.
This research defines use of alcohol, tobacco, cocaine, and other illicit drug use as risky health behavior. The use of some substances tend to precede and increase the risk of initiating habitual use of substances among the youth. The data used for this project is drawn from the 1992 and 2017 National Youth Risk Behavior Survey to examine the behavioral difference between two periods. The study examines the relationship between alcohol and illicit drug use and three types of violent behaviors: (1) drunken driving, (2) occupying a car driven by someone who has been drinking, and (3) not wearing seatbelts.
The results show that there is a positive relationship between the risky health behaviors of alcohol and illicit drug uses and social violence (drunken driving, riding in a car driven by a drunken driver, and not wearing seatbelts) among youth. The results suggest that binge drinking, smoking habits, as well as illicit drug use will contribute to the escalation of habitual, high-risk behaviors such as: drunken driving and not using seatbelts, among youth. The results also indicate that youth attitudes toward drunken driving will become more sensitive to multi-consumption habits as they get old. Controlling the consumption of alcohol and drug use at an early age is indeed an important factor in reducing drunken-driving behavior later. Drunken driving behavior is more likely to be a habitual behavior, and to reduce this behavior, access to alcohol and illicit drugs must be restricted among early teens.This audio recording was presented at the first annual Celebration of Undergraduate Research and Creative Activity while the author was an undergraduate student at Rutgers University-Camden
Defect (p,q) five-branes
No full textAbstractWe study a local description of composite five-branes of codimension two. The formulation is constructed by virtue of SL(2,Z)×SL(2,Z) monodromy associated with two-torus. Applying conjugate monodromy transformations to the complex structures of the two-torus, we obtain a field configuration of a defect (p,q) five-brane. This is a composite state of p defect NS5-branes and q exotic 522-branes. We also obtain a new example of hyper-Kähler geometry. This is an ALG space, a generalization of an ALF space which asymptotically has a tri-holomorphic two-torus action. This geometry appears in the conjugate configuration of a single defect KK5-brane
InfIuences on the protein synthesis of rat liver by adrenal surgery
No full textThe author studied on the protein synthesis of rat liver influenced by adrenal surgery. The rat liver conditions were normal, acute medical toxicosis, treated with anticancer agents, and liver cirrhosis. On these conditions, adrenalectomy, or adreno-portal operation was performed and the nessesity of glucocorticoid and importance of albumin were clarified
Self-Organized Synchronization Phenomena in Spatiotemporal Coupled Oscillator Model for Emergent Systems
No full textThe author proposes a spatiotemporal coupled Lorenz model with an excitatory-excitatory connection or an excitatory-inhibitory connection, which consists of three temporal coupling coefficients c1,2,3 and three spatial coupling coefficients d1,2,3. This model is an emergent device that has synchronized three nonlinear oscillators. In this study, the author discovers that self-organized various phase transition phenomena appear in this model in changing the values of c1,2,3 and d1,2,3 in the case of using the excitatory-inhibitory connection. Proposed model also concerns the neural population model for autonomous agent

OBSERVATION AND SIMULATION OF TSUNAMIS INDUCED BY THE 2003 TOKACHI-OKI EARTHQUAKE (M 8.0)
No full textThe 2003 Tokachi-oki earthquake (MJ 8.0) occurred off the southeastern coast of Tokachi, Japan, and generated a large tsunami which arrived at Tokachi Harbor at 04:56 with a wave height of 4.3 m. Japan Marine Science and Technology Center (JAMSTEC) recovered records of water pressure and sea-bed acceleration at the bottom of the tsunami source region. These records are first introduced with some findings from Fourier analysis and band-pass filter analysis. Water pressure disturbance lasted for over 30 minutes and the duration was longer than those of accelerations. Predominant periods of the pressure looked like those excited by Rayleigh waves. Next, numerical simulation was conducted using the dynamic tsunami simulation technique able to represent generation and propagation of Rayleigh wave and tsunami, with a satisfactory result showing validity and usefulness of this technique.
