After transitioning from periodic to model-based control policy for fire blight blossom infection, it is crucial to provide the timing of field application with easy and accurate information. To assess the risk of blossom infection, Maryblyt was employed in 31 sites across apple-producing regions nationwide, including areas prone to fire blight outbreaks, from 2021 to 2023. In 2021 and 2023, two and seven sites experienced Blossom Infection Risk-Infection warning occurrences among 31 sites, respectively. However, in 2022, most of the sites observed Blossom Infection Risk-Infection from April 25 to 28, highlighting the need for blossom infection control. For the comparison between the two model-based control approaches, we established treatment 1, which involved control measures according to the Blossom Infection Risk-Infection warning and treatment 2, aimed at maintaining the Epiphytic Infection Potential below 100. The analysis of control values between these treatments revealed that treatment 2 was more effective in reducing Blossom Infection Risk-Infection and the number of days with Epiphytic Infection Potential above 100, with respective averages of 95.6% and 93.0% over the three years. Since 2022, the implementation of the K-Maryblyt system and the deployment of Automated Weather Stations capable of measuring orchard weather conditions, with an average of 10 stations per major apple fire blight county nationwide, have taken place. These advancements will enable the provision of more accurate and timely information for farmers based on fire blight models in the future.

Compressive sensing (CS) is a newly developed data acquisition and processing technique that takes advantage of the sparse structure in signals. Normally signals in their primitive space or format are reconstructed from their compressed measurements for further treatments, such as modal analysis for vibration data. This approach causes problems such as leakage, loss of fidelity, etc., and the computation of reconstruction itself is costly as well. Therefore, it is appealing to directly work on the compressed data without prior reconstruction of the original data. In this paper, a direct approach for modal analysis of damped systems is proposed by decomposing the compressed measurements with an appropriate dictionary. The damped free vibration function is adopted to form atoms in the dictionary for the following sparse decomposition. Compared with the normally used Fourier bases, the damped free vibration function spans a space with both the frequency and damping as the control variables. In order to efficiently search the enormous two-dimension dictionary with frequency and damping as variables, a two-step strategy is implemented combined with the Orthogonal Matching Pursuit (OMP) to determine the optimal atom in the dictionary, which greatly reduces the computation of the sparse decomposition. The performance of the proposed method is demonstrated by a numerical and an experimental example, and advantages of the method are revealed by comparison with another such kind method using POD technique.

The use of chopped sugarcane stalk (CSS) as a roughage for lactating cows was examined using four Holstein crossbred cows in a private dairy farm in Khon Kaen, Thailand, in comparison with rice straw (RS), which is the conventional roughage in the dry season in the region. Cows were subjected to the following two dietary treatments: Diet 1) RS with commercial concentrate feed, and Diet 2) CSS and RS with commercial concentrate feed. The diet was switched over every 3 weeks. The amount of concentrate was determined by the experience of the owner of the cows. RS and CSS were given ad libitum. There was no difference in milk production between two groups, although the total DMI was less in cows fed CSS. Solid-not-fat (SNF) content in milk was significantly higher in the cows given CSS. The NEFA content was significantly lower in the animals given CSS, which suggested that cows given only RS as roughage would be suffering from energy malnutrition. Therefore, it was considered that CSS feeding improved energy supply, which resulted in higher SNF in milk. In the nutritional point of view, the present study clearly showed CSS can be used as a roughage for dairy cows in the dry season.

Background: Coccygodynia is one of the chronic, refractory painful musculoskeletal disorders. Interventional procedures are applied to patients unresponsive to initial treatment in coccygodynia. This study aims to compare the treatment outcomes of ganglion impar block (GIB) and caudal epidural steroid injection (CESI) in patients with chronic coccygodynia. Methods: This study was a prospective randomized comparison study conducted between June 2019 and January 2021. Patients diagnosed with chronic coccygodynia were randomly divided into two groups: the GIB group and the CESI group. The severity of pain, presence of neuropathic pain, and quality of life were evaluated using the Numeric Rating Scale, Leeds Assessment of the Neuropathic Symptoms and Signs Scale, and Short Form-12 Health Survey (SF-12), respectively. Results: A total of 34 patients in each group were included in the final analyses. While there was a significant decrease in pain intensity in both groups in the 3-month follow-up, this decrease was more significant in the GIB group at the 3rd week. There was a significant improvement in the SF-12 physical score and the number of patients with neuropathic pain in both groups in the 3rd week, but this improvement was not observed in the 3rd month. Conclusions: Although GIB may provide more pain relief in short term, both GIB and CESI are useful treatment methods in coccygodynia unresponsive to more conservative treatments.

Objective : This study is performed to compare older with younger groups about clinical characteristics and overall outcome of treatments for the intracranial aneurysms. Methods : We retrospectively investigated 633 patients with cerebral aneurysms who were admitted to our institute from January 2000 to May 2004. The authors divided the patients of cerebral aneurysm into two groups, one the third, fourth decades and the other eighth, ninth decades, analyzed clinical characteristics and overall outcome of treatments. Results : There were 57 patients [9.0%] under 39years old and 58 patients [9.2%] over 70. The female to male sex ratio was 0.5 : 1 in the younger group[YG] and 7.3 : 1 in the older group[OG], showing a female predominance with increasing age. In the YG, aneurysms were found in anterior communicating artery[A-com] [44.8%], middle cerebral artery [31.0%]. In the OG, aneurysm of posterior communicating artery [30.1%] was most common followed by that of A-com [26.9%]. More smokers and alcoholics were found in the YG. Older age was related to poor Hunt-Hess grade, Fisher's grade on admission, high incidence of unruptured aneurysms, and endovascular surgery. There was a higher prevalence of hypertension, intraventricular hematoma, hydrocephalus, and rebleeding in the preoperative state in the OG and postoperative complications including hydrocephalus, subdural fluid collection, and systemic complications. Overall outcome was poorer with advancing age [p=0.01]. Conclusion : The patients with aneurysms in the YG have distinct characteristics compared to those in the OG. Because of a good clinical grade on admission, a thin subarachnoid clot, and Low incidence of perioperative complications, the overall outcomes of the young patients were better than those of the old patients.

PURPOSE. To evaluate the adhesion to CAD/CAM feldspathic blocks by failure analysis and shear bond strength test (SBSt) of different restorative systems and different surface treatments, for purpose of moderate chipping repair. MATERIALS AND METHODS. A self-adhering flowable composite (Vertise Flow, Kerr) containing bi-functional phosphate monomers and a conventional flowable resin composite (Premise Flow, Kerr) applied with and without adhesive system (Optibond Solo Plus, Kerr) were combined with three different surface treatments (Hydrofluoric Acid Etching, Sandblasting, combination of both) for repairing feldspathic ceramics. Two commercial systems for ceramic repairing were tested as controls (Porcelain Repair Kit, Ultradent, and CoJet System, 3M). SBSt was performed and failure mode was evaluated using a digital microscope. A One-Way ANOVA (Tukey test for post hoc) was applied to the SBSt data and the Fisher's Exact Test was applied to the failure analysis data. RESULTS. The use of resin systems containing bi-functional phosphate monomers combined with hydrofluoric acid etching of the ceramic surface gave the highest values in terms of bond strength and of more favorable failure modalities. CONCLUSION. The simplified repairing method based on self-adhering flowable resin combined with the use of hydrofluoric acid etching showed high bond strength values and a favorable failure mode. Repairing of ceramic chipping with a self-adhering flowable resin associated with hydrofluoric acid etching showed high bond strength with a less time consuming and technique-sensitive procedure compared to standard procedure.

Purpose: There was no controlled study on botox injection and neurectomy for treatments of muscle hypertrophy. Although many studies have shown the clinical effects of each treatment, it was not able to evaluate and compare the effects of each treatment because there was no comparison of the two treatments under the same experimental condition. Hence, the aim of this study is to com Methods: The study was carried out on 21 rabbits. 9 rabbits received botox injection(botox injection group), and neurectomy was performed to another 9 rabbits (neurectomy group). 3 rabbits did not receive any treatment(control group). To compare and analyze the effects of muscular atrophy, muscle was stained with NADH-TR, and the changes in size of the muscle fiber were examined. And the electromyography was examined. In each group, muscle fiber was stained and electromyography was performed 2, 3, and 6 months after injection or operation. Results: In histological test and electromyography, in the neurectomy group, the size of muscular fiber and amplitude of electromyography decreased until 2 months after neurectomy. And decreased results were maintained with the passage of time. It showed irreversible aspect. On the other hand, in the botox injection group, the decrease in the size of muscular fiber and amplitude of electromyography was observed until 2 months after injection. In 3 months after the injection, it was slowly getting back to original size and had almost recovered by 6 months after the injection. It showed reversible aspect. Conclusion: This study shows researches about clinical effect of botox injection and neurectomy coincide with the results of experiment under the same experimental condition.
