Ossifying fibromas are benign fibro-osseous tumors of mesenchymal origin. Although ossifying fibromas have principally been found in the jaw, they have also been reported in the frontal, ethmoid, sphenoid, and temporal bones, as well as the orbit and anterior cranial fossa. Ossifying fibromas affecting the jaw exhibit variable behaviors ranging from slow growth to occasionally aggressive local destruction. In the present article, we discuss a differential diagnosis considered for maxillary swellings and report a rare case of ossifying fibroma occurring in the maxilla.

Background: With the increasing use of narcotic analgesics, the Ministry of Food and Drug Safety has been operating the National Narcotics Information Management System (NIMS) since 2018 in Korea. Some studies are related to the narcotic analgesics use, but the evaluation studies of system, including NIMS users are insufficient. Objective: This study evaluated the NIMS enforcement process through in-depth interviews on the experience of using NIMS of doctors and pharmacists who prescribe or dispense opioid analgesics. Methods: Participants in this study were selected through purposeful sampling as three doctors and two pharmacists in the metropolitan area. The interviews were conducted from August 27 to October 19, 2022. Each interview was analyzed using a phenomenological method. Results: Six components of this study included "Doctors and pharmacists come across drug abusers", "They respond individually to drug abusers", "They use NIMS tailored to the needs of system managers", "They are concerned about the role of NIMS in practice settings", "They face challenges against drug abusers" and "They find a way to utilize the system to deal with drug abusers." The interviews confirmed that doctors and pharmacists used NIMS little in their work, and they only reported data. Therefore, it might be difficult for doctors and pharmacists to take measures for the safe use of narcotic analgesics. Conclusion: It is likely that adding data-feedback and medication-check function can reduce the abuse of narcotic analgesics. In the future, further studies on the evaluation of the empirical results of NIMS and review of systems in other countries will be required.

We used in-situ synchrotron X-ray scattering to investigate phase transformations of octahedral tilted monoclinic $SrRuO_3$ (MSRO) and tetragonal SRO (TSRO) thin films on $SrTiO_3$ (STO) substrates. The octahedral tilted MSRO thin films were highly crystalline and the monoclinic distortion angle was $0.45^{\circ}$. The phase transition temperature from the MSRO to TSRO phase occurred at approximately $200^{\circ}C$ as a second order transition. Conversely, no phase transformations of the TSRO thin film occurred within the range from RT to $250^{\circ}C$. The octahedral $RuO_6$ rotation was strongly affected by the phase transformation in the SRO thin films.

In this letter, we have introduced copper chloride ($CuCl_2$) as an additive in the $CH_3NH_3PbI_3$ precursor solution to improve the surface morphology and crystallinity of $CH_3NH_3PbI_3$ films in a single solvent system. Our optimized perovskite solar cells (PSCs) with 2.5 mol% $CuCl_2$ additive showed best power conversion efficiency (PCE) of 15.22%. The PCE of the PSCs fabricated by $CuCl_2$ (2.5 mol%) additive engineering was 56% higher than the PSC fabricated with pristine $CH_3NH_3PbI_3$.

Adenoid cystic carcinoma is a rare epithelial tumour, and comprises about 1% of all malignant tumours of the oral and maxillofacial region. It is a malignant tumour which may develop in the trachea, bronchus, lungs or mammary glands, in addition to the head and neck region. Occurrences in the head and neck are mostly detected in the major salivary gland, oral cavity, pharynx and paranasal sinus where it presents as a slow growing firm nodular swelling. The aim of the article is to highlight the unique presentation of adenoid cystic carcinoma as a solitary ulcer on the floor of the mouth.

In April 2001, many Japanese national institutes were reorganized as Independent Administrative Institutions (IAI) based on the General Act for Independent Administrative Institutions and the act for each institution. Under the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the National Institute for Materials Science (NIMS) was established by the merger of the National Research Institute for Metals (NRIM) and the National Institute for Research in Inorganic Materials (NIRIM). One of the biggest changes was the expansion of autonomous administration. The nanotechnology and material R&D field was prioritized in the 2nd (2001-2005) and the 3rd (2006-2010) Science and Technology Basic Plans; subsequently, NIMS was assigned to take the initiative in nanotechnology as well as materials science. NIMS has proactively expanded research fields through the introduction of researchers from polymers, electronics, and biotechnology as well as member institutes of the World Materials Research Institute Forum (WMRIF). Globalization has been promoted through programs that include the International Center for Young Scientists (ICYS) and the International Center for Materials Nanoarchitectonics (MANA). The 4th Science and Technology Basic Plan (2011-2015) emphasizes outcomes-recovery and rebirth from the disaster, green innovation, and life innovation. The Midterm Plan for NIMS also follows it. R&D collaboration by multi-partners (that include industry, university, and GRI) should be strategically promoted where GRI are especially required to play a hub function for innovative R&D and open innovation. NIMS highlights are Tsukuba Innovation Arena (TIA) and the Nanotechnology Platform Project. On January 20, 2012, a new organization was decided on by the Japanese Government where several IAI from different science and technology areas will be merged to realize more effective R&D as well as administrative cost reductions. NIMS is also supposed to be merged with 4 other R&D IAI under MEXT by the end of 2013.

For the allergy patient who needs to know the situation about the extent of pollen risk, the National Institute of Meteorological Sciences developed a pollen forecasting system based on the Community Multiscale Air Quality Modeling (CMAQ). In the old system, pollen emission from the oak was estimated just based on the airborne concentration and meteorology factors, resulted in high uncertainty. For improving the quality of current pollen forecasting system, therefore the estimation of pollen emission is now corrected based on the observation of pollen emission at the oak forest to better reflect the real emission pattern. In this study, the performance of the previous (NIMS2014) and current (NIMS2016) model system was compared using observed oak pollen concentration. Daily pollen concentrations and emissions were simulated in pollen season 2016 and accuracy of onset and end of pollen season were evaluated. In the NIMS2014 model, pollen season was longer than actual pollen season; The simulated pollen season started 6 days earlier and finished 13.25 days later than the actual pollen season. The NIMS2016 model, however, the simulated pollen season started only 1.83 days later, and finished 0.25 days later than the actual pollen season, showing the improvement to predict the temporal range of pollen events. Also, the NIMS2016 model shows better performance for the prediction of pollen concentration, while there is a still large uncertainty to capture the maximum pollen concentration at the target site. Continuous efforts to correct these problems will be required in the future.

Backgrounds/Aims: Open cholecystectomy is becoming obsolete and laparoscopic cholecystectomy has become the treatment of choice in gallstone diseases. Difficult gallbladders are encountered whenever there is a frozen calot's triangle, obliterated cystic plate, or both. Rather than converting to open procedure, there has been a growing preference for laparoscopic subtotal cholecystectomy (LSC) during difficult gallbladders. This study aimed to assess the advantages, indications, and viability of LSC in difficult gallbladders. Methods: The study included patients undergoing laparoscopic cholecystectomy in NIMS Hospital, Jaipur, from January 2021 to January 2023. Data of the patients who underwent LSC for difficult gallbladders included demographics, comorbidities, operative time, conversion to open cholecystectomy, length of hospital stay, and complications. LSC was classified into three types depending on the part of the gallbladder remnant. Results: A total of 728 patients underwent laparoscopic cholecystectomy. Among them, 41 patients (5.6%) were attempted for LSC. However, one patient was converted to an open procedure and the rest 40 underwent LSC. LSC was divided into 3 types, 4 patients underwent LSC type I, 34 patients underwent type II, and 2 patients type III. The average operating time and postoperative length of hospital stay were 86.2 minutes and 2.1 days, respectively. Two patients had surgical site infection. No patient had a bile leak and none required intensive care unit care. Conclusions: LSC is a safe and feasible option for use in difficult gallbladders.
