The Rotational Spectrum of Chloroform in Its Ground and Excited Vibrational States

CARPENTER, JOHN H.,SEO, PIL JA,WHIFFEN, DAVID H. 동의대학교 기초과학연구소 1996 基礎科學硏究論文集 Vol.6 No.1

The rotational spectrum of the ground state, the excited A states v₃, 2v₃and probably v₂, and the lowest E state v_6 of CH^35Cl₃have been measured. The ground state microwave spectrum was analyzed to obtain nuclear quadrupole coupling constants. These are consistent with the electric field gradient at each chlorine nucleus being cylindrically symmetrical about the C-Cl bond. Rotation-vibration parameters were obtained for all vibrational states. The spectrum of the doubly degenerate v_6 state showed strong / resonance, which enabled the centrifugal distortion constant D_K and the Coriolis coupling constant ζ_6 to be determined.

The Millimeter-Wave Spectrum of CF₃C^35Cl₃in Its Ground and Excited Vibrational States

CARPENTER, J. H.,FRASER, K. A.,SEO, P. J.,SMITH, J. G. 동의대학교 기초과학연구소 1993 基礎科學硏究論文集 Vol.3 No.1

The millimeter-wave rotational spectrum of CF₃C^35Cl₃ has been recorded. Fro the ground state, the results are in agreement with previous work;the very small value of D_JK results in no measurable k-splitting. The rotational spectra of the torsional states have been recorded for v^6=1 to v^6=5. In addition, the rotational spectrum in the lowest doubly degenerate excited state has been analysed to yield values of the l-resonance parameters q₁^+=0.7474(6) MHz and Aζ₁=283.2(2) MHz.

Photogrammetric 3D Scanning of Asphalt Cores for Automatic Layer Detection and Gradation Classification

Joshua Carpenter,정진하,이주상 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.8

Asphalt cores are routinely drilled from existing roadways and manually tested to determinethe thickness of individual layers and classify the gradation of the aggregate mixture withineach layer. This process is time-consuming, hazardous, and destroys the sample core. Thisstudy presents a non-destructive, close-range photogrammetry-based 3D scanning method fordetermining the layer divisions and aggregate gradation within asphalt cores. The proposedmethod uses structure-from-motion techniques to produce distortion-free images of thecylindrical surface of the core exposed during drilling. From these images, the asphalt mixgradation is determined from the exposed cross sections of aggregate within the core. Ourmethod achieved a 75% classification accuracy and did not damage the sample, leaving thecore intact for other uses. Additionally, we also find that surface image-based methods forgradation curve generation tend to underestimate the amount of smaller aggregate within amix and show signs of higher variability in detecting the largest sizes of aggregate. This studydemonstrates that the close-range photogrammetry-based 3D scanning technology can easilybe developed into an automatic and non-destructive tool for asphalt core analysis.

Ending South Korea`s Unhealthy Security Dependence

( Ted Galen Carpenter ) 한국국방연구원 1994 The Korean Journal of Defense Analysis Vol.6 No.1

The Mutual Security Treaty between the United States and the Republic of Korea (ROK) is no longer in the best interests of either party. The alleged benefits to the United States of the military relationship are increasingly diffi- cult to identify. Maintaining the forces needed to come to the aid of South Korea costs American taxpayers billions of dollars each year. The US troops stationed on the peninsula would also be disastrously entangled in any con- flict that erupted between North and South Korea. Moreover, one of the dangers entailed in shielding the ROK from aggres- sion may soon be the need to deter a nuclear-armed North Korea. Contrary to the belief of those who contend that Pyongyang`s nuclear program demon- strates the need to preserve the US-South Korean alliance, the increased risk to American forces is another argument for prompt disengagement. The risk of nuclear war should never be undertaken except in defense of a nation`s most vital interests, and in the post-Cold war world, South Korea is a periph- eral, not a vital, US interest. Although the alliance with the United States saves South Korean taxpay- ers $10 billion to $12 billion a year in additional military expenditures, the ROK`s status as a US security dependent contains serious liabilities for the Korean people. Seoul relies on the United States to a dangerous degree for air and naval power and other crucial components of its defense. That reliance could prove fatal in a crisis if the US response were tardy or insufficient. The Clinton administration`s initial intent to adopt a "win-hold-win```` strategy for dealing with two simultaneous regional conflicts underscored the potential danger, as ROK officials immediately recognized. The ROKs security dependence also creates a more subtle peril. Seoul could be dragged into a needless conflict beecause of actions taken by its protector. A decision by Washington to take harsh measures against North Korea in the ongoing dispute over Pyongyang`s nuclear program, for exam- ple, could easily trigger a general war on the peninsula. Yet Seoul has little control over policy on a matter that so directly affects its vital interests. ROK leaders can only urge their US counterparts to be prudent and hope they will remain so. Washington should establish a definite timetable (which should not exceed three years) for the withdrawal of all US forces and the termination of the Mutual Security Treaty. A three-year transition period would give the ROK adequate time to build up its conventional forces and to decide whether to acquire a modest nuclear arsenal to deter the North. South Korea, with twice the population of the North and an economy twelve times as large, has the resources to develop whatever forces are needed to protect its security. A pol- icy of self-reliance is also, on balance, in the ROK`s own best interest.

Great Expectations: Washington, Beijing, and the North Korean Nuclear Crisis

( Ted Galen Carpenter ) 한국국방연구원 2006 The Korean Journal of Defense Analysis Vol.18 No.4

Throughout the North Korean nuclear crisis, the Bush administration has believed that China is the most crucial player in the effort to find a solution. Washington has frequently expressed disappointment that Beijing is not willing to put more pressure on its misbehaving client. China faces a dilemma, however. Although most evidence indicates that Chinese leaders are not happy about Pyongyang`s quest for nuclear weapons, keeping the Korean peninsula nonnuclear is not China`s highest priority. Beijing is even more concerned about preserving North Korea as a geographic buffer between the U.S. sphere of influence in Northeast Asia and the Chinese homeland. China does have substantial economic leverage over North Korea, since it supplies a major portion of the country`s food and energy supplies. The PRC is cautious, however, about using that leverage to coerce Pyongyang regarding the nuclear issue. Chinese leaders fear that putting too much pressure on Kim Jong Il`s regime could cause the North Korean state to unravel, leading to massive refugee flows into China and the emergence of a united Korea allied to the United States. The latter development would put American military forces in a country directly on the border of the PRC, something that Chinese officials would consider highly undesirable. Washington needs to be more realistic about China`s willingness to put pressure on Pyongyang. Beijing will try to be helpful on the nuclear problem, as it has been already, but China sees itself as an intermediary in the crisis, not as a U.S. partner in a campaign to coerce North Korea. Given Washington`s high expectations and China`s ongoing caution, the potential exists for serious misunderstandings and significant damage to the U.S.-PRC relationship.

Enhanced numeracy skills following team-based learning in United States pharmacy students: a longitudinal cohort study

Purpose The literature suggests that the ability to numerate cannot be fully understood without accounting for the social context in which mathematical activity is represented. Team-based learning (TBL) is an andragogical approach with theoretical links to sociocultural and community-of-practice learning. This study aimed to quantitatively explore the impact of TBL instruction on numeracy development in 2 cohorts of pharmacy students and identify the impact of TBL instruction on numeracy development from a social perspective for healthcare education. Methods Two cohorts of students were administered the Health Science Reasoning Test-Numeracy (HSRT-N) before beginning pharmacy school. Two years after using TBL as the primary method of instruction, both comprehensive and domain data from the HSRT-N were analyzed. Results In total, 163 pharmacy student scores met the inclusion criteria. The students’ numeracy skills measured by HSRT-N improved after 2 years of TBL instruction. Conclusion Numeracy was the most significantly improved HSRT-N domain in pharmacy students following two years of TBL instruction. Although a closer examination of numeracy development in TBL is warranted, initial data suggest that TBL instruction may be an adequate proxy for advancing numeracy in a cohort of pharmacy students. TBL may encourage a social practice of mathematics to improve pharmacy students’ ability to numerate critically.
