This study applied LDA topic modeling analysis to collect and analyze news media big data related to face masks in the three waves of the COVID-19 pandemic in Korea. The results empirically show that media reports focused on mask production and distribution policies in the first wave and the mandatory mask wearing in the second wave. In contrast, more reports on trivial, gossipy events consist of the media coverage in the second and third waves. The findings imply that Korea's governmental interventions to address the shortage of face masks and to regulate mask wearing were successful relatively in a short time. In contrast, the study also reports that there may be relative less number of science-based news reports like the ones on the effectiveness of face masks or different levels of filter types. This study exemplifies how a big data analysis can be applied to evaluate and enhance public health communication.

Clinicians often have difficulties diagnosing patients with subtle phenotypes of Noonan syndrome phenotypes. Facial recognition technology can help in the identification of several genetic syndromes with facial dysmorphic features, especially those with mild or atypical phenotypes. A patient visited our clinic at 5 years of age with short stature. She was administered growth hormone treatment for 6 years, but her growth curve was still below the 3rd percentile. She and her mother had wide-spaced eyes and short stature, but there were no other remarkable features of a genetic syndrome. We analyzed their photographs using a smartphone facial recognition application. The results suggested Noonan syndrome; therefore, we performed targeted next-generation sequencing of genes associated with short stature. The results showed that they had a mutation on the PTPN11 gene known as the pathogenic mutation of Noonan syndrome. Facial recognition technology can help in the diagnosis of Noonan syndrome and other genetic syndromes, especially in patients with mild phenotypes.

Improvements in jaw relationship through clockwise rotation of the mandible may be desirable in some Class III patients with short low facial height. The aim of this study was to examine the treatment effect of face mask for Class III malocclusion patients according to their low facial morphology. Methods: Class III patients in their pubertal growth period were divided into two groups (Group 1, high LFH; Group 2, low LFH) according to lower facial height (LFH) by Ricketts (norm, 47). treatment changes between groups after face mask treatment was compared not only for hard tissue but also for soft tissue. Results: There were no significant differences between the two groups for the skeletal and soft tissues of the maxilla. There were no significant differences between the two groups for the skeletal posterior movement of the mandible, but posterior movement of the mandibular soft tissues in group 2 was larger than group 1. There were no significant differences between the two groups for the vertical hard tissue proportion changes of the mandible, but the vertical soft tissue proportion changes of the mandible in group 2 was larger than group 1. There was a significant correlation between the sagittal hard tissue and soft tissue changes of the maxilla and mandible, but there was no significant difference in the vertical changes. Conclusion: The clockwise rotation of the mandible occurred from use of the face mask, and posterior movement of soft tissues of the mandible was higher in Cl III patients with low LFH than with high LFH.

Robinow syndrome or fetal face syndrome is a rare inherited disorder characterized by short stature, mesomelic brachymelia, hypoplastic genitalia, and a typical facial appearence ("fetal face") with frontal bossing, hypertelorism, ear abnormalities, a short upturned nose, long philtrum, micrognathia, and macrocephaly. Intraoral features have included quite a few dental cavities, crowding, hypoplastic uvula, cleft lip or/and cleft palate, gingival hyperplasia, alveolar hyperplasia, enamel hypoplasia, delayed eruption, and congenital missing of the permanent teeth. We report on a 10 years old girl with Robinow syndrome. The patient had most of the typical anomalies of the syndrome and negative family history but, in addition, had mental retardation, hearing loss, and serous otitis media. Intraoral findings included dental cavities, crowding, hypoplastic uvula, repaired cleft palate, and mouth breathing. Dental treatment and V-tube insertion(by dept. of ENT) were performed under general anesthesia. In all cases of Robinow syndrome, thorough evaluation and united treatments with medical specialists should be performed.

While online surveys are considered to be the viable alternative to face-to-face and telephone surveys, many clients express a strong concern about the possibility of unreliable responses. Given this concern, survey experts hypothesize that amounts of time on responding can represent the extent to which respondents fill out the questions with sincerity. This study examines this hypothesis using data from an online survey sample of 1.052. Results strongly suggest that while "long time" informants are reliable, "short time" informants are not. Those in the short time group spend only 2.4 seconds per question and show very different patterns of responses to 49 Likert -typed questions. Logistic regression results imply that these unreliable respondents are interested in monetary gifts and maybe as a result, participate in surveys much more frequently. In conclusion, we provide some implications of these results to the quality of online surveys.

Purpose: This study was conducted to investigate the effects of preparatory nursing information and information offering by SMS on anxiety and nursing satisfaction among family members of ICU (Intensive Care Unit) inpatients. It utilized a quasi-experimental research design with a non-equivalent and non-synchronized control group. Methods: The experimental group and the control group were offered a booklet guiding ICU and were offered face-to-face information by nurses using Power Point. The experimental group was additionally offered SMS (short message service) message on patient's safety at night every morning during the hospital stay between 8 and 9 am. All participants in the experimental group and the control group were measured in reference to anxiety at the point of hospitalization and were surveyed anxiety and nursing satisfaction on the third day of hospital stay. Results: The anxiety demonstrated no significant difference between the groups, while the nursing satisfaction was significantly higher in the experimental group than that of the control group. Conclusion: Proving direct information and indirect information via SMS message were considered effective in improving the family member's satisfaction with nursing care. The frequencies of SMS message and the contents of the message and information need to be defined and specified in the given population.

In this study, we prepared reference data needed for clothing design for middle-aged women by analyzing body satisfaction of their body shape, which had been classified by collecting body features of middle-aged women. As for the study method, we have set five scales from 'never satisfied' to 'very much satisfied,' after analyzing body features of middle-aged women by measuring their body shape through the body meter and auxiliary tools. We used the SPSS 12.0 statistics program, and the results are the following: Body shapes of middle-aged women can be classified into the following four types. A middle-age women with an 'A silhouette' has a normal height, but fat nether limbs. A 'Y silhouette' is short with a fat upper body. The 'O silhouette' is short with fat nether limbs and upper body, and 'H silhouette' is tall and thin. Body shape I has displayed satisfaction with her own body shape, and body shape II showed the most dissatisfaction compared to other body shapes. Body shape III showed satisfaction on all items except face size and breast size, whereas body shape IV was dissatisfied with her face size, neck length, shape of her breast, waist, and buttocks. The result of this study is expected to contribute in accomplishing clothing production that will satisfy the desire of the consumers in the clothing business, while being utilized as the basic data for clothing design that fits their body shape by grasping the changing patterns of their body shape.

In addition to the Fourth Industrial Revolution, interest and research on medical information are actively being conducted. As the technologies using short-range low-power wireless communication are applied in connection with mobile devices, the utilization of them in medical institutions is gradually increasing, and the demand of customers who want to receive high-quality services using IT technology is increasing in the medical environment according to the development and change of technology. In addition, modern people who are familiar with smart equipment and consider the value of time is important do not waste their time through rapid service. In addition, as the recent epidemics including Coronavirus Disease 2019 (COVID-19) have become popular, interest in untapped (non-face-to-face) has increased, and social distance is needed as a preliminary measure against infectious diseases. For this reason, this study studied the untapped-based medical reception system to provide quick service to patients using short-range low-power wireless communication and to provide safer and more comfortable environment for medical staff and visitors.

We report magnetic resonance image (MRI) and magnetic resonance spectroscopy (MRS) findings in a patient of cerebral fat embolism (CFE) occurred in a 26-year-old woman after an autologous fat injection into the face. After initial neurologic symptom onset, MRI and MRS data were obtained two times to investigate repeated CFE. We obtained the MRS data in the two different time intervals and two different echo times to compare the lesions with normal brain parenchyma. The results of MRS data showed that a decrease in N-acetyl-aspartate, an increase in lactate and a very high early peak of free lipids between 0.9 and 1.4 ppm were obtained at the acute infarcted lesion as compared with normal brain parenchyma. In addition, these findings were more clearly detected on short echo time spectrum rather than long spectrum. A close relationship between the clinical manifestations and MRI and MRS findings of the brain can helpful to distinguish CFE with other conditions and to evaluate the cause materials of infarctions rather than conventional MRI or diffusion-weighted imaging.

Purpose: This study has aimed to examine the relationship among self-esteem, Activities of Daily Living (ADL) and depression reported by hospitalized elderly patients with chronic diseases. Methods: A descriptive correlation study by means of a self-report questionnaire or face-to-face interview was used to collect data from 119 elderly patients who were hospitalized in a General Hospital from January 5 to February 25, 2010. Their levels of depression was measured using Short-Form Geriatric Depression Scale, self esteem using Jeon's, and activities of daily living using K-ADL. Results: 80.7% of the subjects experienced depression. Depression correlates with self-esteem (r=-.67) and ADL (r=.45). The influencing factors on depression were self-esteem, ADL, subjective health status, and family support satisfaction ($R^2=.57$), while self esteem in itself explained 45% of variance in depression. Conclusion: These findings indicate the importance of early detection of depression, which starts from the admission of patients and the continuing evaluation/management in daily life after discharge to ensure their well-being and quality of life. The development of program empowering self esteem, ADL and subjective health status with adequate family support during hospitalization and in daily life is indispensible.
