Factors Associated with Treatment Outcome of Carbon Dioxide Laser for Trigeminal Neuralgia

Abstract:Objective: To report the treatment outcome and identify factors associated with treatmentoutcome of using carbon dioxide (CO2) laser neural ablation for trigeminal neuralgia (TN).Materials and methods: This was a retrospective study of 36 patients who underwent CO2laser neural ablation to treat TN. The medical records were reviewed and analyzed. Pain relief for atleast 1 year after the procedure would be classified as treatment success.Results: For the total of 36 patients, 15 of them (41.7%) achieved the treatment success.Regarding the factors associated with the treatment outcome, the total daily dose of carbamazepineof 600 mg or less per day and shorter duration of symptoms prior to receiving the operation(persistent symptom of 3 years or less) were related to success of treatment. The odds ratios ofboth factors were 12 (95% CI = 1.6-87.9) for the carbamazepine dose, and 16 (95% CI = 2.2-112.9)for the duration of persistent symptom of 3 years or less.Conclusions: The CO2 laser neural ablation decreased the pain symptoms of the patientswith TN. The preoperative dose of carbamazepine and the duration of symptoms prior to treatmentwere associated with good treatment outcomes of CO2 laser for TN.Keywords: Trigeminal neuralgia, Tic Douloureux, Carbone dioxide laser, LasersSWU Dent J. 2022;15(2):79-88

A Development of Educational Assembly Model to Promote People Participation

The objectives of this research were 1) to design and develop the educational assembly model 2) to test and improve the designed educational assembly model and 3) to propose policy implication for implementing the educational assembly model to promote people participation in educational provision. The designed educational assembly model was examined by experts and stakeholders and tested at the provincial level in eight provinces. The findings revealed that the “Triple Three Educational Assembly Model: 333 Model” was an essential add appropriate tool to promote people participation in education. The first “Three” refers to three levels of educational assembly comprise of the provincial level, the provincial cluster level, and the national level. The second “Three” refers to three components of educational assembly comprise of knowledge sector, people sector, and government sector. The third “Three” refers to three key activities comprise of knowledge research and development, assembly meeting, and monitoring of meeting resolutions. The research suggested that he Office of Education Council should set up a task force for the implementation of the educational assembly to promote people participation in educational provisio

A Comparative Study of Educational Cooperation between Thailand and Neighboring Countries: Lao PDR and Cambodia

The objectives of this research were 1) to compare the educational cooperation between Thailand and Cambodia, and Laos PDR; 2) to compare the outcomes of educational cooperation on human development and international understanding; and 3) to provide policy recommendations for the future prospects of educational cooperation. Documentary and survey research were applied. The participants were 503 key Thai, Cambodian, and Laotian informants. The research results showed that since 1992 to 2010, Thailand had educational cooperation time with Lao PDR longer than Cambodia, which started in 2000, and had 4 main educational cooperation projects more than 3 of Cambodia. Focusing on the participants, 30,612 Laotian and 14,752 Cambodians were educated; most of the Laotians had completed Grade 12 with professional skills training while most of Cambodians had completed professional skills training. Between and after participation with the projects, the highest increasing element among Cambodian coordinators was ‘the value of peace and international interests’ (PNI 1.26) while that of the Laotian coordinators was ‘recognizing and appreciating diversity among the two countries’ and ‘recognizing interdependence and connections among them’ (PNI 0.74). The highest increasing element among Cambodian and Laotian beneficiaries was ‘developing personal knowledge to live across cultures’ (PNI 1.05 and 0.83, respectively)

Quantum chaos for nonstandard symmetry classes in the Feingold-Peres model of coupled tops

We consider two coupled quantum tops with angular momentum vectors $\mathbf{L}$ and $\mathbf{M}$. The coupling Hamiltonian defines the Feinberg-Peres model which is a known paradigm of quantum chaos. We show that this model has a nonstandard symmetry with respect to the Altland-Zirnbauer tenfold symmetry classification of quantum systems which extends the well-known threefold way of Wigner and Dyson (referred to as `standard' symmetry classes here). We identify that the nonstandard symmetry classes BD$I_0$ (chiral orthogonal class with no zero modes), BD$I_1$ (chiral orthogonal class with one zero mode) and C$I$ (antichiral orthogonal class) as well as the standard symmetry class A$I$ (orthogonal class). We numerically analyze the specific spectral quantum signatures of chaos related to the nonstandard symmetries. In the microscopic density of states and in the distribution of the lowest positive energy eigenvalue we show that the Feinberg-Peres model follows the predictions of the Gaussian ensembles of random-matrix theory in the appropriate symmetry class if the corresponding classical dynamics is chaotic. In a crossover to mixed and near-integrable classical dynamics we show that these signatures disappear or strongly change.Comment: 15 page

POLITICAL PARTY INSTITUTIONALIZATION FROM A COMPARATIVE PERSPECTIVE: THE CASE OF THAILAND

This article examines the importance of institutionalizing political parties in developing democracy. This article develops the conceptual framework of the institutionalization of political parties, which combines institutionalization factors in both internal and external dimensions and applies this conceptual framework to extract lessons on the institutionalization of political parties in various democratic countries, including Thailand. The results of applying the aforementioned conceptual framework, in particular to the case of Thailand, indicate that the failure to apply the notion of institutionalization to political parties in this country stems from the traditionally narrow-minded approach to considering the institutionalization of political parties rather than problems with the idea itself. Thus, this article suggests that building an institution for a political party is something that can be designed by giving importance to the development of political parties in a structured manner, along with promoting political parties to have the ability to play a solid political role under the democratic regime.

Psychological Factors Influencing Speeding Intentions of Car Drivers and Motorcycle Riders in Urban Road Environments

The aim of this study was to examine and compare psychological factors influencing car drivers’ and motorcycle riders’ speeding intentions (IN), using the Theory of Planned Behaviour (TPB). The psychological factors modules included Attitude (AT), Subjective Norm (SN) and Perceived Behavioural Control (PBC). These were employed to explain speeding intentions in urban road environments. A sample of 188 car drivers and 174 motorcycle riders were collected from the two universities within Khon Kaen, Thailand. The Structural Equation Model (SEM) was used to examine and explain speeding intentions. The results indicated that the TPB could explain 33% and 41% of the variance of intentions by car drivers and motorcycle riders, respectively. The most significant psychological factor for car drivers was determined by attitude (AT), while the speeding intention of motorcycle riders was attributed to perceived behavioural control (PBC). The authorities in Khon Kaen Province should determine safety policies that can improve these psychological factors, which could have various effects or outcomes on changing car drivers’ and motorcycle riders’ speeding intentions. The outcome of this study could help to understand car drivers’ and motorcycle riders’ speeding intentions in urban road environments and it could be useful for development of safety measures

Cross-cultural Differences in Speeding Intentions of Drivers on Urban Road Environments in Asian Developing Countries

The aim of this study was to examine and compare the psychological factors influencing driver speeding behavior in 3 cities in Southeast Asia, focusing on developing counties, using the Theory of Planned Behaviour (TPB). Data was collected from 570 respondents in the urban areas of Khon Kaen in Thailand, Vientiane in Laos and Phnom Penh in Cambodia. The psychological factors of TPB include attitude (AT), subjective norm (SN) and perceived behavioral control (PBC). These factors were employed to explain speeding intentions in urban road environments. The Structural Equation Models (SEM) was used to examine and explain speeding intentions. The results indicated that the TPB could explain the variance by intentions of drivers in Khon Kaen, Vientiane and Phnom Penh at 33%, 46%, and 84%, respectively. The most significant of the psychological factors for Khon Kaen drivers was determined by AT, while the speeding intentions of Vientiane drivers and Phnom Penh drivers were determined by PBC. From this data, the authorities of each city should create and implement safety policies that can improve these psychological factors, which could have a positive effect on drivers’speeding intentions in urban road environments. The outcome of this study could be useful for understanding the speeding attitudes of drivers in three different countries and would be beneficial for the development and introduction of preventative safety measures in these countries as well
