This study was conducted to examine the superior factors and the perception of Korean traditional foods by college students studying in food related industries. The subject group consisted of 65.0% of the students majoring in food service & culinary arts, 12.9% of the students majoring in food & nutrition, and 7.3% of the students majoring in baking & pastry. The nutritional value was evaluated as the top superior factor of Korean traditional foods by the study subjects. In addition, 92.4% of reported that they had eaten Korean traditional foods in the past, 76.8% of whom responded that the reason for having Korean traditional foods was its time-honored tradition. 'Cooking for oneself' was considered to be the most popular way (78.2%) of obtaining Korean traditional foods, while the traditional market (58.6%) was the most popular place to purchase the foods. 'Not having enough time' (47.2%) was the primary reason for not having Korean traditional foods, although 72.9% of the subjects reported that they wanted to learn about Korean foods. 'Standardization of taste, nutritional value, and recipes' was found to be the most important factor (41.3%) required to increase the consumption of Korean traditional foods. Additionally, 56.1% of the subjects responded that they feel there is a need for modernization of the cuisine to meet the taste of the general public. However, 61.4% of the subjects responded that the succession of traditional dietary culture was the primary reason for developing traditional cuisine, which indicates that there is a bright future for Korean traditional foods.

Objectives: Anterior maxillary sinus wall fractures are common in all types of maxillofacial trauma. They can result in various complications, including injury to the surrounding nerves. Owing to its anatomy, trauma to the maxillary antrum can result in injury to the middle superior alveolar nerve (MSAN) and the anterior superior alveolar nerve (ASAN). The purpose of this study is to evaluate neurosensory deficits (NSD) present in maxillary gingiva, incisors, and premolars after injury to the anterior wall of the maxillary antrum. Materials and Methods: This prospective study was conducted among 39 patients sustaining unilateral fractures of the anterior maxillary sinus wall. Clinical neurosensory tests including two-point discrimination and fine touch discrimination were performed to classify the extent of nerve injuries as mild, moderate, severe, or anesthetic. Additional temperature discrimination and pulpal sensibility tests (electric pulp testing and cold testing) were carried out. A comparison of radiographic fracture patterns and severity of nerve injury was done. Testing was carried out immediately after trauma and at 2-month follow-up. Results: More than half of the patients assessed in the study group presented with NSD of the teeth and gingiva after trauma. The incidence of deficits varied with the type of test used to measure them. Most frequently, patients presented with both loss of two point as well as fine touch discrimination thresholds. Severe nerve injuries were associated with loss of temperature discrimination clinically and displaced fractures radiographically. There was no significant relationship between the recovery of pulpal and gingival sensation. The patterns of injury and recovery in ASAN and MSAN were similar. Conclusion: NSD after trauma to the maxillary antrum is relatively common. Clinical loss of temperature discrimination and radiographic signs of fracture lines passing through the canalis sinuosus are predictors of persistent and severe oral NSD.

Background Despite its many advantages, prepectoral breast reconstruction also carries the risk of implant rippling. The recent introduction of partial superior implant coverage using a pectoralis muscle slip in prepectoral direct-to-implant (DTI) breast reconstruction has shown the potential to minimize upper pole rippling. The purpose of this study was to identify factors associated with rippling and the effectiveness of our surgical technique. Methods In total, 156 patients (186 breasts) who underwent prepectoral DTI breast reconstruction between August 2019 and March 2021 were identified retrospectively. Patient data were analyzed from medical records. Univariable and multivariable logistic analyses were performed to contextualize the risks associated with rippling deformity relative to demographic characteristics and other clinical factors. Retrospective propensity-matched analysis was performed to identify the relationship between rippling deformity and the reconstruction method. Results Patients with body mass index (BMI; odds ratio [OR], 0.736; p < 0.001), those with a postoperative chemotherapy history (OR, 0.324; p = 0.027) and those who received breast reconstruction via the superior coverage technique (OR, 0.2; p = 0.004), were less likely to develop rippling deformity. The median follow-up period was 64.9 weeks, and there were no significant differences between patients in types of mastectomy, implant, or acellular dermal matrix. Patients who underwent superior coverage technique-based reconstruction showed significantly reduced rippling (OR, 0.083; p = 0.017) Conclusion Patients with higher BMI and prior postoperative chemotherapy were less likely to develop rippling deformity. The superior coverage technique can be effective in minimizing upper pole rippling.

Background: This study aimed to identify exact anatomical landmarks and ideal injection volumes for safe adductor canal blocks (ACB). Methods: Fifty thighs from 25 embalmed adult Korean cadavers were used. The measurement baseline was the line connecting the anterior superior iliac spine (ASIS) to the midpoint of the patellar base. All target points were measured perpendicular to the baseline. The relevant cadaveric structures were observed using ultrasound (US) and confirmed in living individuals. US-guided dye injection was performed to determine the ideal volume. Results: The apex of the femoral triangle was 25.3 ± 2.2 cm distal to the ASIS on the baseline and 5.3 ± 1.0 cm perpendicular to that point. The midpoint of the superior border of the vasto-adductor membrane (VAM) was 27.4 ± 2.0 cm distal to the ASIS on the baseline and 5.0 ± 1.1 cm perpendicular to that point. The VAM had a trapezoidal shape and was connected as an aponeurosis between the medial edge of the vastus medialis muscle and lateral edge of the adductor magnus muscle. The nerve to the vastus medialis penetrated the muscle proximal to the superior border of the VAM in 70% of specimens. The VAM appeared on US as a hyperechoic area connecting the vastus medialis and adductor magnus muscles between the sartorius muscle and femoral artery. Conclusions: Confirming the crucial landmark, the VAM, is beneficial when performing ACB. It is advisable to insert the needle obliquely below the superior VAM border, and a 5 mL injection is considered sufficient.

Corticostriatal connections of auditory areas within the rostral and caudal portions of the superior temporal gyrus (STG) and in the supratemporal plane(STP) of pigtail macaque (Macacca nemestrina) were studied with particular emphasis on specific projections to the ventral striatum. Retrograde tracers were Injected into five different regions of the ventral striatum such as the ventromedial caudate nucleus, ventral shell, central shell, dorsal core of the nucleus accumbens (NA), and ventrolateral putamen to Identify the cells of origin. There were only few projections from the auditory areas in the STP to the ventral striatum. However, the association (or belt) areas of the STG collectively had widespread corticostriatal projections characterized by differential topographic distributions. The rostral parts of the STG strongly projected to the ventromedial caudate nucleus. The midportion of the STG also projected to the same ventral striatal regions, but the connections were relatively less extensive. Interestingly, the caudal portion of the STG had no connection to all subregions of the ventral striatum. These differential patterns of corticostriatal connectivity suggest that the ventromedial caudate nucleus would be a major auditory convergence area and mainly involved in sound recognition rather than spatial localization of sound sources.

Recent progress of electric technology requires new piezoelectric crystals having superior properties such as zero temperature coefficients and large electromechanical coupling factors. We have developed a series of new leading chandidates, La$_3$Ga5SiO14(langasite, LGS), La3Nb0.5Ga5.5O14(LNG), La3Ta0.5O14(LTG), to satisfy those requirements. High quality LGS, LNG and LTG single crystals, with dimensions of 2 inches in diameter, were successfully grown by the Czochralski method at a pulling rate of 1mm/h. Since no variation of chemical composition was observed when whole melt in a crucible was crystallized, congruency of these compositions was confirmed. Physical constants such as elastic constants, dielectric constants and piezoelectric constants were measured. Filters and oscillators made of grown LGS, LNG and LTG single crystals showed superior properties such as three times wider passband than that of quartz, low insertion loss and easy processing, Langasite family crystals were shown to be superior materials to other known materials such as quartz, LiTaO$_3$, $\alpha$-AlPO$_4$ and Li$_2$B$_4$O7.

The fullerene solar cells are becoming a feasible choice due to the advanced developments in donor materials and improved fabrication techniques of devices. Recently, sufficient optimization and improvements in the processing techniques like incorporation of solvent vapor annealing (SVA) with additives in solvents has become a major cause of prominent improvements in the performance of organic solar cell-based devices . On the other hand, the challenge of reduced open circuit voltage (V_oc) remains. This study presents an approach for significant performance improvement of overall device based on organic small molecular solar cells (SMSCs) by following a two step technique that comprises thermal annealing (TA) and SVA (abbreviated as SVA+TA). In case of exclusive use of SVA, reduction in V_oc can be eliminated in an effective way. The characteristics of charge carriers can be determined by the measurement of transient photo-voltage (TPV) and transient photo-current (TPC) that determines the scope for improvement in the performance of device by two step annealing. The recovery of reduced V_oc is linked with the necessary change in the dynamics of charge that lead to increased overall performance of device. Moreover, SVA and TA complement each other; therefore, two step annealing technique is an appropriate way to simultaneously improve the parameters such as V_oc, fill factor (FF), short circuit current density (J_sc) and PCE of small molecular solar cells.

The 2nd, 3rd, 4th 6th cranial nerve and the ophthalmic division of the 5th cranial nerve are derived from the optic foramen and superior orbital fissure. When these contents are attacked by a trauma the superior orbital fissure syndrome or the more severe orbital apex syndrome are onsetted. As their treatment we can consider the conservative treatment with the hypertonic solution and steroid. Also we can consider the more radical surgery. But their indications are debatable. As the emergency state the treatment plan requires rapid decision and very much considerations equaly. And the legal problems can be happened.
