Purpose: This study was done to examine the incidence of pressure ulcers and associated factors, by inspecting the skin of newborn babies in a newborn unit or newborn intensive care unit (NICU). Methods: The participants were 101 newborn babies in either a newborn unit or NICU in D general hospital. The incidence of pressure ulcer was measured using the skin inspection tool for pressure ulcer, suggested by Agency for Health Care Policy and Research. Results: Incidence rate of pressure ulcer was 19.8%, and 80% of the newborns with pressure ulcers were premature babies. The commonest region of onset was the ear (36.8%), followed by the foot (31.6%), occipital region (15.8%) and knee (15.8%). Those are the regions related to external medical devices like nasal Continuous Positive Airway Pressure and Pulse Oximetry. Factors related to pressure ulcers were gestational period of 37 weeks or less, hospitalization for 7 days or more, birth weight under 2,500 g and a low level of serum albumin. Conclusion: The results of the study show that the skin and underlying tissues of premature infants is at risk for pressure-related skin breakdown. As most pressure ulcers are caused by medical devices, nursing interventions are required to prevent further aggravation of the lesions.

This study was conducted in 2021 using Kwangpyeongok and Gangdaok, that showed good yield performance both under upland and lowland conditions in the previous year. The experiments were carried out by sowing on April 22, May 14, May 30, June 19, and July 10, with aim to determine optimum sowing date in central region of Korea. The growing degree days (GDD) required to read the flowering stage were 1375.5-1725.3℃ for upland and 1582.7-1982.4℃ for lowland condition. The lowest GDD was observed in July 10 sowing regardless of ridge formation both under lowland and upland conditions for Kwangpyeongok. However, Gangdaok showed the lowest GDD under no-ridge in lowland and high-ridge in upland, both of which were sown on June 19. The difference in GDD between no-ridge and high-ridge treatment was little depending on the sowing date. In both lowland and upland, there was no significant difference between no-ridge and high-ridge treatments in stover dry matter, ear dry matter, and TDN between no-ridge and high-ridge treatments. Under upland condition, no significant difference in biomass and TDN was observed among sowing date treatments and between varieties. Under lowland condition, biomass production was severely reduced in May 30 sowing treatment, whereas no varietal difference was observed. Reduced biomass in May 30 sowing treatment may be due to excess waterlogging and lodging by rainfall.

Bovine embryonic stem cells have potential for use in research, such as transgenic cattle generation and the study of developmental gene regulation. The Nanog may play a critical role in maintenance of the undifferentiated state of embryonic stem cells in the bovine, as in murine and human. Nevertheless, efforts to study the bovine Nanog for pluripotency-maintaining factors have been insufficient. In this study, in order to understand the mechanisms of transcriptional regulation of the bovine Nanog, the 5'-flanking region of the Nanog was isolated from ear cells of Hanwoo. Results of transient transfection using a luciferase reporter gene under the control of serially deleted 5'-flanking sequences revealed that the -134 to -19 region contained the positive regulatory sequences for the transcription of the bovine Nanog. Results from mutagenesis studies demonstrated that the Sp1-binding site that is located in the proximal promoter region plays an important role in transcriptional activity of the bovine Nanog promoter. The electrophoretic mobility shift assay with the Sp1 specific antibody confirmed the specific binding of Sp1 transcription factor to this site. In addition, significant inhibition of Nanog promoter activity by the Sp1 mutant was observed in murine embryonic stem cells. Furthermore, chromatin-immunoprecipitation assay with the Sp1 specific antibody confirmed the specific binding of Sp1 transcription factor to this site. These results suggest that Sp1 is an essential regulatory factor for bovine Nanog transcriptional activity.

The styloid process is a slender, cylindrical bony outgrowth located immediately in front of the stylomastoid foramen and fused to the inferior aspect of the temporal bone. The elongated styloid process is not so frequent and the styloid syndrome is a dull, nagging pain in the oropharynx, often referred to the ear and the mastoid region. The symptoms are secondary stimulation of the nerves and vessels which pass close to the tip of the process. The clinical diagnosis is certain if the elongated styloid process is palpated through the tonsillar area. Radiologic investigation give information about the length of the styloid process and medial angulation. The treatment of choice is surgical shortening of the process. Recently, the authors experienced a case of elongated styloid syndrome misdiagnosed as pharyngeal neurosis in a 28 year-old male patient.

Rhinoliths are foreign bodies composed of mineralised deposits in the nasal cavity that are rarely encountered in routine dental practice. The current report presents a case of a 77-year-old female patient who visited a dental treatment centre for a routine dental check-up and prophylaxis. On the clinical examination, the patient did not report any breathing difficulty, nasal obstruction, or any form of discharge. Panoramic radiography showed a horizontally magnified radiopaque structure in the right nasal fossa region. Cone-beam computed tomography (CBCT) revealed a hyperdense entity with a laminated presentation in the right nasal fossa. The hyperdense entity was diagnosed as a rhinolith based on the radiographic findings. Although the patient was asymptomatic, a referral was made to an ear, nose, and throat surgeon for a further evaluation. This report highlights the importance of CBCT imaging in the diagnosis of soft-tissue calcifications.

Cholesterol granuloma is a disease in which cholesterol crystals act as a foreign substance in the surrounding tissues and cause granulomatous reaction and fibrosis within the chamber. It is found in various locations of the body, but the most common location is the temporal bone associated with middle ear disease. Because the disease is associated with breathing disturbance, it may also occur in the paranasal sinus. However, it has been rarely reported since its first report by Graham and Michaels in 1978. Recently, we experienced a case of cholesterol granuloma of the right maxillary sinus of a 63-year-old female patient without any nasal symptoms. We successfully managed this case with Caldwell-Luc operation. Also, we summarized the cases of cholesterol granuloma of the sinonasal region reported in Korea.

Schwannomas are benign tumors of neuroectodermal origin and can be found in any part of the body. Although schwannomas are common in the head and neck region, they are rare in the auricle. Auricular schwannomas are rarely symptomatic but the mass itself or a surgical procedure to remove it may disrupt the complicated structure of the auricle. We report a rare case of auricular schwannoma with a literature review and describe the surgical technique used in this case.

Cervical chondrocutaneous branchial remnants are very rare congenital lesions of the lateral neck; thus, our knowledge of this condition derives almost entirely from occasional case reports in the literature. They are thought to originate from the branchial arches and, therefore, can be found anywhere on the pathway along which those branchial arches migrate during embryogenesis. We report the case of a 5-year-old girl presenting with a cervical chondrocutaneous branchial remnant on the right lateral neck that had existed since birth, with no other anomalies.

Total 15 different corn hybrids, Kwangpyeongok, Gangdaok, Yanganok, Singwangok, Jangdaok, Cheonganok, Cheongdaok, Andaok, Dapyeongok, Pyeongkangok, Pyeonganok, Daanok, Sunwon P3394, Gangilok, P3394, had been used to investigate the plant growth and yield of corn hybrids depends on the sowing date. Sowing dates were April 5th, June 25th, and July 5th and all experiments had three repeats. The growth of Gangdaok was the best. However, in the case of Kwangpyeongok, the growth was not the best to compare with Gangdaok, but the stem to ear height ratio was lower than Gangdaok, it may be better for the stable cultivation. Both of the growth and yield of Daanok was not good regardless of planting date, but the yield and ear shape of Pyeongkangok and Dapyeongok were good for fresh corn. The growth and yield of 15 different corn hybrids were variable depends on the planting date, however, the growth degree days (GDD) was the most important factor for the maturity of the corn. More than $1500^{\circ}C$ of GDD was enough to harvest mature corn hybrids in the central region of Korea. Besides the yield and growth, other characters such as sweetness and taste as a food should be investigated further for the fresh corn to be suggested.
