BACKGROUND: Weight overestimation of Korean Americans may be associated with dietary habits and preferences for foods and tastes. METHODS: The subjects were 100 Korean Americans in New York City and LA and 100 Koreans in Seoul, who were 20-29 years old. Self-reported questionnaire consisted of age, height, weight, length of residence in US, preferences for 10 foods and 5 tastes, dietary habits and perception of self body image. Korean Americans were further divided into 3 groups according to length of residence in US. RESULTS: More Korean American women underestimated (27.3% vs. 5.8%), and less overestimated their body weights, than Korean women (31.8% vs. 53.8%, P=0.008). Korean Americans who overestimated their own body weights had significantly higher preference for salty taste and significantly lower dietary habit score regarding regular meals. CONCLUSIONS: Overestimation of self body size, rather than longer residence in US may be associated with the undesirable dietary habit and taste preference of Korean Americans, highlighting the importance of correct body image.

Purpose: We reviewed the cases of occupational diseases that occurred in healthcare workers from 2010 to 2019 and the cases of epidemiological investigations conducted by the Occupational Safety and Health Research Institute for them. Methods: In this study, gender, age, working period, occupational characteristics, and disease characteristics by occupation, which are general characteristics of healthcare workers approved for occupational diseases. In addition, 32 cases of epidemiological investigation of healthcare workers conducted by the Institute for Occupational Safety and Health for the past 10 years (2010~2019) were analyzed. Results: The gender, age, working period, occupational characteristics, and disease characteristics by occupation of medical workers recognized as occupational diseases were all statistically significant (p<.001). In the epidemiological investigation, ionizing radiation( 50.0%) and stress (33.3%) were recognized as disease-related factors, and even in cases of disapproval, ionizing radiation (60.0%) and shift work (25.5%) were designated as related factors. And it was statistically significant (p=.008). Conclusion The current study identified the types of diseases, various causes, and general characteristics and occupational characteristics that occur frequently in healthcare workers. Therefore, if this study is used as basic information to set the priority and direction of disease prevention project for healthcare workers, it is judged that it will be helpful in preventing industrial accidents.

BACKGROUND: This study examined the role of neutrophilc oxidative stress in an O2-induced acute lung injury (ALI). METHODS: For 48 h, experimental rats were exposed to pure oxygen (normobaric hyperoxia) in a plastic cage. Forty-eight hours after O2 breathing, the rats were sacrificed and the parameters for ALI associated with neutrophilic oxidative stress were assessed. RESULTS: Normobaric pure oxygen induced ALI, which was quite similar to ARDS. The O2-induced neutrophilic oxidative stress was identified by confirming of the increase in lung myeloperoxidase, BAL neutrophils, malondialdehyde (MDA), cytosolic phospholipase A2 (cPLA2) activity in the lung, histological changes and BAL cytospin morphology. CONCLUSION: In part, ALI-caused by oxygen is affected by neutrophils especially by the generation of free radicals.

PURPOSE: This paper identified the effects of kangaroo care (KC) on maternal self-esteem and the growth and physiological stability of premature infants hospitalized in the neonatal intensive care unit. METHODS: The experiment was conducted with an experimental group of 17 infants, and a control group of 17 infants selected by convenience sampling. KC was given to the infants one time a day for 30 minutes after feeding for two weeks. Their weight was measured every morning, and their physiological stability was measured in terms of their body temperature, respiratory rate, heart rate, oxygen saturation, and stability of the cardio-respiratory system in premature infants (SCRIP) score, as physiological responses at every 10 minutes during the intervention. Maternal self-esteem was assessed by a maternal self-report inventory. RESULTS: The experimental group showed significant increase in the self-esteem of mothers. Also, KC was effective on physiological stabilization of preterm infants. CONCLUSION: This study suggests that KC can be provided in clinical settings more widely in Korea as one of the nursing interventions aimed at promoting maternal self-esteem as well as infants' physiological stabilization.

PURPOSE: To compare photon thunderbird with deep match (technique 1) with 3-field technique with electron inguinal boost (technique 2) in acute skin toxicity, toxicity-related treatment breaks and patterns of failure in elective inguinal radiation therapy (RT) for curative chemoradiation in anal cancer. MATERIALS AND METHODS: Seventeen patients treated between January 2008 and September 2010 without evidence of inguinal and distant metastasis were retrospectively reviewed. In 9 patients with technique 1, dose to inguinal and whole pelvis area was 41.4 to 45 Gy and total dose was 59.4 Gy. In 8 patients with technique 2, doses to inguinal, whole pelvis, gross tumor were 36 to 41.4 Gy, 36 to 41.4 Gy, and 45 to 54 Gy, respectively. The median follow-up period was 27.6 and 14.8 months in group technique 1 and 2, respectively. RESULTS: The incidences of grade 3 radiation dermatitis were 56% (5 patients) and 50% (4 patients), dose ranges grade 3 dermatitis appeared were 41.4 to 50.4 Gy and 45 to 54 Gy in group technique 1 and 2, respectively (p = 0.819). The areas affected by grade 3 dermatitis in 2 groups were as follow: perianal and perineal areas in 40% and 25%, perianal and inguinal areas in 0% and 50%, and perianal area only in 60% and 25%, respectively (p = 0.196). No inguinal failure has been observed. CONCLUSION: Photon thunderbird with deep match technique and 3-field technique with electron inguinal boost showed similar incidence of radiation dermatitis. However, photon thunderbird with deep match seems to increase the possibility of severe perineal dermatitis.

Epidermoid cysts are rare benign lesions in the oral cavity that may be either congenital or acquired. The cysts are usually slow-growing and asymptomatic until becoming secondarily infected or large enough to interfere with mastication and speech. Consequently, diagnosis is often delayed. The condition is also uncommon in newborns and infants. Most of the lesions occur in the floor of the mouth and rarely in the upper lip. This report describes the case of a 29-month-old girl with a palpable mass in the inner mucosa of the upper lip. The lesion was surgically enucleated using an intraoral approach and histopathologically diagnosed as epidermoid cyst.

The purpose of this study is to evaluate the position of the mandibular foramen and location and morphological characteristics of the mandibular lingula using Cone-Beam Computed Tomography (CBCT).
Mandibular CBCT images of children aged 6 - 16 years were collected. A total of 180 patients were divided into 3 groups, 6 - 7, 10 - 11 and 15 - 16 years, with 30 male and female patients per group. Either side of the ramus was analyzed. The shortest distances from the anterior, posterior, superior and inferior border of the ramus to the mandibular lingula were measured. The shortest distance between the mandibular lingula and the mandibular foramen was also measured. The vertical distance from the mandibular lingula and the mandibular foramen to the occlusal plane was measured. The shapes of the mandibular lingula was classified into 4 types according to the criteria.
The distances of the mandibular lingula from the anteroposterior and vertical reference points of the ramus increased in all directions with age. The distance between the mandibular lingula and the mandibular foramen also increased with age. The location of the mandibular lingula and the mandibular foramen in relation to the occlusal plane moved upwards with age. The most common shape of the mandibular lingula was triangular, followed by nodular, truncated and assimilated, and there was no difference in the shape according to age.
It is recommended that the horizontal insertion point of the anesthesia from the anterior border of the ramus increased to 17 mm, 18 mm, and 19 mm according to the age groups. It is also suggested that the vertical insertion point increased by 2 - 3 mm, 5 - 6 mm and 9 - 10 mm above the occlusal plane according to the age groups.

PURPOSE: The purpose of this study was to develop and validate the Communication Behavior Scale for nurses caring for people with Dementia (CBS-D). METHODS: Based on communication accommodation theory, the initial items were generated through a literature review and interviews with 20 experts. Content and face validity of the initial items were assessed. Data from 486 nurses caring for people with dementia were analyzed using item analysis, exploratory and confirmatory factor analysis, criterion-related validity, and internal consistency. RESULTS: The final scale consisted of 18 items and four factors (discourse response management, interpersonal control, emotional expression, and interpretability) that explained 57.6% of the variance. Confirmatory factor analysis indicated that the theoretical model with 18 items satisfied all goodness-of-fit parameters. Criterion-related validity was shown by the Global Interpersonal Communication Competence Scale (r=.506, p < .001). Cronbach's alpha for the total scale was .88. CONCLUSION: The CBS-D can be used to measure the communication behavior of nurses caring for people with dementia.

A 1-year-old male Persian cat was presented for castration. Liver incarcerated in a peritoneopericardial diaphragmatic hernia (PPDH) was diagnosed through pre-anesthetic tests. Multiple homogeneous hyperechoic nodules in the hepatic parenchyma were identified using ultrasound. The nodules showed decreased attenuation compared with normal hepatic parenchyma, and the herniated hepatic parenchyma showed increased arterial and decreased portal enhancement on computed tomography. From the histopathology, we diagnosed hydropic degeneration with portal fibrosis and myelolipoma. This report presents diagnostic imaging features of hepatic myelolipoma incarcerated in a PPDH in a cat. When perfusion of the hepatic parenchyma is altered, surgical treatment should be considered.
