The genes that are located within the odvp-6e/odv-e56 region of the Choristoneura fumiferana granulovirus (ChfuGV) were identified by sequencing the 11 kb BamHI restriction fragment on the ChfuGV genome. The global GC content that was calculated from the data obtained from this genomic region was 34.96%. The open-reading frames (ORFs), located within the odvp-6e/odv-e56 region, are presented and compared to the equivalent ORFs that are located at the same region in other GVs. This region is composed of 14 ORFs, including three ORFs that are unique to ChfuGV with no obvious homologues in other baculoviruses as well as eleven ORFs with homologues to granuloviral ORFs, such as granulin, CfORF2, pk-1, ie-1, odv-e18, p49, and odvp-6e/odv-e56. In this study, the conceptual products of seven major conserved ORFs (granulin, CfORF2, IE-1, ODV-E18, p49 and ODVP-6E/ODV-E56) were used in order to construct phylogenetic trees. Our results show that granuloviruses can be grouped in 2 distinct groups as follows: Group I; Choristoneura fumiferana granulovirus (ChfuGV), Cydia pomonella granulovirus (CpGV), Phthorimaea operculella granulovirus (PhopGV), and Adoxophyes orana granulovirus (AoGV). Group II; Xestia c-nigrum granulovirus (XcGV), Plutella xylostella granulovirus (PxGV), and Trichoplusia ni granulovirus (TnGV). The ChfuGV conserved proteins are most closely related to those of CpGV, PhopGV, and AoGV. Comparative studies, performed on gene arrangements within this region of genomes, demonstrated that three GVs from group I maintain similar gene arrangements.

Objective: The present study investigated sperm chromatin quality and testosterone levels in acrylamide-treated mice and the possible protective effects of vitamin E on the fertility potential of spermatozoa. Methods: Thirty-two adult male mice were divided equally into four groups. Group 1 was the control, group 2 received acrylamide (10 mg/kg, water solution), group 3 received vitamin E (100 mg/kg, intraperitoneal), and group 4 received both acrylamide and vitamin E. After 35 days, spermatozoa from the right cauda epididymis were analyzed in terms of count, motility, morphology, and viability. Sperm DNA integrity and chromatin condensation were assessed by acridine orange (AO), aniline blue (AB), toluidine blue (TB), and chromomycin A3 (CMA3) staining. Results: In acrylamide-treated mice, significantly lower sperm concentration, viability, motility, and testosterone levels were found in comparison with the control and acrylamide+vitamin E groups (p< 0.05). In the vitamin E group, significantly more favorable sperm parameters and testosterone levels were found than in the other groups (p< 0.05). There were also significantly more spermatozoa with less condensed chromatin in the acrylamide-treated mice than in the other groups. Moreover, significantly more spermatozoa with mature nuclei (assessed by AB, CMA3, AO, and TB staining) were present in the vitamin E group than in the control and acrylamide+vitamin E groups. Conclusion: This study revealed the deleterious effects of acrylamide on sperm parameters and sperm chromatin quality. Vitamin E can not only compensate for the toxic effects of acrylamide, but also improve sperm chromatin quality in mice.

The purpose of this study was to investigate the treatment pattern of patients with neuropathic pain (NeP) in Korea through computerized database of Health Insurance Review and Assessment Service (HIRAS) over three years' period from 2003 to 2005. The results showed that the numbers of treatment visits were the highest for diabetic neuropathy (DN), followed by postherpetic neuralgia (PHN) and trigeminal neuralgia (TN) in order. Top 3 specialties for treatment visits due to NeP conditions were neurology, neurosurgery and anesthesiology. While cost of a treatment visit was higher in anesthesiology and emergency clinics compared to other clinics, there was a tendency to increase costs for visits to clinics of rehabilitation medicine and family medicine over the three years. Cost of dental visits was relatively high for TN, atypical facial pain (AFP) and atypical odontalgia (AO). Surgeries frequently applied to patients with NeP were sympathetic plexus or ganglion block, block of peripheral branch of spinal nerve and cranial nerve or its peripheral branch block. Most common prescribed medication were anticonvulsants, anti-inflammatory analgesics and anti-psychotic drugs while anti-inflammatory analgesics were overwhelmingly frequently prescribed for AO and glossodynia. Based on the results of this study, NeP disorders more relevant to dentists were AO, TN and AFP, TN of which seems to be the most important in terms of patients' number and cost for treatment visits. This indicates that dentists, especially oral medicine specialists should actively participate in management of TN, AO and AFP and share relevant information with patients and community.

The dioxygen transfer reaction from $N^5$-ethyl-4a-hydroperoxy-3-methyllumiflavin anion (4a-FlEtOO-) has been extended to isomeric aminophenol systems (1a-4a). O-aminophenol (o-AP, 1a & 2a) and p-aminophenol(p-AP, 3a & 4a) were turned out to be good substrates, whereas m-aminophenol(m-AP, 5a) was not. This is due to the charge location which is not on the carbon bearing the amino group. o-AO's react with 4a-FlEtOO- to give isophenoxazine derivatives (6 & 7) and with p-AP's to produce p-benzoquinone derivatives (8 & 9). The partition coefficients $(k_2/k_3)$ of 1a & 2a were $4.84{\times}10^{-4}\;&\;1.66{\times}10^{-5}M$, respectively and those of methylated aminophenolates, 2a & 4a were 4-10 times greater than nonmethylated substrates, 1a & 3a.

Target operational availability setting is the first step to setting up a goal which a weapon system development project have to achieve and doing RAM analysis during whole life of a weapon system. It is important as a key factor to doing RAM analysis in the early phase of weapon system development. This paper present a methodology to set a target operational availability for, especially, a warship when it develop. This methodology uses Operational Mode Summary/Mission Profile(OMS/MP) of the developing warship and RAM analysis results of similar warships to calculate wartime and peacetime target operational availability. It will be used in early phase of not only warship development but also army or aircraft weapon systems when these develop.

Traditional attire has assumed a pivotal role within the contemporary fashion industry. The objective of this study is to construct a computer vision model tailored to the recognition of traditional costumes originating from five distinct countries, namely India, Korea, Japan, Tanzania, and Vietnam. Leveraging a dataset comprising 1,608 images, we proceeded to train the cutting-edge computer vision model YOLOv8. The model yielded an impressive overall mean average precision (MAP) of 96%. Notably, the Indian sari exhibited a remarkable MAP of 99%, the Tanzanian kitenge 98%, the Japanese kimono 92%, the Korean hanbok 89%, and the Vietnamese ao dai 83%. Furthermore, the model demonstrated a commendable overall box precision score of 94.7% and a recall rate of 84.3%. Within the realm of the fashion industry, this model possesses considerable utility for trend projection and the facilitation of personalized recommendation systems.

The experiments reported here investigated whether seeing a speaker's face (visible speech) affects the perception and memory of Korean speech sounds. In order to exclude the possibility of top-down, knowledge-based influences on perception and memory, the experiments tested people with no knowledge of Korean. The first experiment examined whether visible speech (Auditory and Visual - AV) assists English native speakers (with no knowledge of Korean) in the detection of a syllable within a Korean speech phrase. It was found that a syllable was more likely to be detected within a phrase when the participants could see the speaker's face. The second experiment investigated whether English native speakers' judgments about the duration of a Korean phrase would be affected by visible speech. It was found that in the AV condition participant's estimates of phrase duration were highly correlated with the actual durations whereas those in the AO condition were not. The results are discussed with respect to the benefits of communication with multimodal information and future applications.

Herein, we report the case of a 60-year-old man, a smoker with a history of arterial hypertension and diabetes mellitus. After computed tomography (CT) for an episode of hemoptysis, the patient underwent elective thoracic endovascular aortic repair (TEVAR) because of a degenerative aneurysm of the descending thoracic aorta. The area of perianeurysmal pulmonary atelectasis reported on the CT scan was not considered. Three months later, he developed an aortopulmonary fistula without endoleaks. Although TEVAR is a relatively safe procedure, no detail should be overlooked in the preoperative evaluation in order to avoid life-threatening complications. Further, the effectiveness and modality of prolonged antibiotic prophylaxis and/or preoperative respiratory physiotherapy should be assessed in such cases.

Simple rules for predicting nonbonded interactions have been proposed. It was found that an end-to-end nonbonded interaction is either attractive or repulsive depending on the sign of the product of AO coefficients of two end atoms in the HOMO of a closed shell conjugated system with a crowded structure. The nonbonded attraction becomes the greatest in a 4N + 2 electron conjugated system, while it is repulsive in a 4N electron system. For 4N + 1 and 4N - 1 electron systems, it is attractive but the effect is less than that in 4N + 2 system. As a result of the attractive interaction, the overlap population of an atom pair increases (decreases) if the HOMO is antibonding (bonding) for the atom pair. The rules were illustrated with some examples.
