Rupture of a bronchus is an unusual result of blunt trauma to the chest. We experienced a case of bronchial rupture caused by blunt chest trauma without external wound or rib fracture. This case was a 13 years old male who was elementary school student. He was compressed on anterior chest by basket ball goal post being failed down on the afternoon of admission day. After this accident, he was suffered from progressive dyspnea and chest pain. The bronchial rupture was confirmed by bronchogram, The operation was performed through standard posterolateral thoracotomy incision along the 5th rib course. The right upper lobe bronchus and intermediate bronchus was completely transected. The right upper lobectomy was done. The ruptured intermediate bronchus was connected direct simply. Post-operative course was uneventful. Thus we report this case of traumatic bronchial rupture with review of literature.

The purpose of this study was to determine the effect of high voltage pulsed current (HVPC) stimulation on proliferative activities of basal keratinocytes by measured nucleolar organizer region (NOR) expression and thickness of spinous layer in aged rat skin. Fifty-one weeks old twelve male Sprague-Dawley rats (300∼350g) were divided into control and HVPC stimulation groups. Each animal's hair on the back were removed. The HVPC stimulation group received an negative monophasic twin peak pulsed current stimulation with 50 V, while the control group was given the same treatment without electricity. The rats were sacrificed after 3 weeks. The biopsy specimens were fixed in formalin, embedded in paraffin and stained with hematoxyline-eosin and silver nitrate. The thickness of basal to granular layer of the epidennis were measured using a light microscope and computerized image analysis system. The number of argyrophilic nucleolar organizer region (AgNOR) were counted using a light microscope and computerized image analysis system and calculated as the mean number of AgNOR per nucleus in the basal keratinocyte. By using a Student's t-test, an increase in the thickness of basal-spinous layer (P<0.001) of epidermis can be observed in HVPC stimulation rats as compared with the control rats, whereas the thickness of the granular layer is not affected. A Student's t-test showed a significantly higher mean NOR number per nucleus of the basal keratinocyte in the HVPC stimulation rats than control rats (P<0.001). There was significantly positive correlation between the NOR number and the thickness of basal-spinous layer (r=0.80, P<0.05). These results suggest that the HVPC stimulation may increase the thickness of spinous layer in the epidennis due to increased proliferative activities of basal keratinocytes in epidennis in aged rat skin.

Purpose: The purpose of this study is to compare sociocultural attitudes toward appearance, appearance satisfaction, and peer relationships between male and female middle school students, and to compare the effects of these variables on self-esteem in students of different genders. Methods: Data were collected in August and September of 2023 and analyzed using SPSS 24.0. Data were collected from 289 male and 240 female students through a survey, and descriptive statistics, x2 test, t-test, Scheffé test, and multiple regression analysis were conducted. Results: Female students showed significantly higher scores for sociocultural attitudes toward appearance (3.06±0.77 vs. 2.82±0.74), significantly lower scores for appearance satisfaction (2.55±0.46 vs. 2.71±0.40), and significantly higher scores for peer relationships (3.46±0.69 vs. 3.00±0.78) than male students. Additionally, self-esteem was significantly lower in female students (2.84±0.59) than in male students (2.95±0.51). As a result of adjusting for weekly allowance, subjective academic achievement, family economic status, stress, and experience of sadness or despair, which were significant in the univariate analysis, self-esteem increased as appearance satisfaction (p for all <.001) and peer relationships increased in both male (p=.009) and female (p<.001) students. In addition, sociocultural attitudes toward appearance did not have a significant impact on self-esteem in both male and female students. Among general characteristics, weekly allowance, subjective academic achievement, and stress were found to have a significant effect on self-esteem in both genders. Relationships with parents had a significant effect on self-esteem only in male students, and experience of sadness or despair had a significant effect only in female students. Conclusion: In order to improve self-esteem in both boys and girls, appearance satisfaction and peer relationships should be improved. As boys with poor relationships with their parents and girls with high levels of sadness or despair are particularly likely to have low self-esteem, they are to be considered as a high-risk group.

The purposes of this study were to investigate 1) the effect of body exposure and color of a woman's suit on the perception of modesty, and 2) the effect of perceiver's sex and age on impression formed by the function of clothing variables. The instrument of this study consisted of a response scale and stimuli. Thirteen items of 7-point semantic differential scales were developed to measure the perceiver's impression on wearer's modesty. Stimuli were color pictures of a model wearing one of 8 types of suit constructed by a 2 $\times$ 2 $\times$ 2 factorial design. The manipulation of each level of the clothing variables were: color of the suit by black and red, leg exposure by varying skirt lengths to a Chanel-line and mini skirt, and neck exposure by shirt collar blouse and scarf. Two models, representing typical female college students living in Seoul, were selected to eliminate model effect. The sample include 384 subjects, consisting of 4 groups of male and female college students and middle aged men and women. Eight experimental groups were randomly assigned to one of eight stimuli based on between-subject design. One half of each group responded to model 1 and the other half to model 2 of same stimulus. Responses to the semantic differential scales were factor analyzed (pc model, Varimax rotation) to identify factors constructing impression of modesty. Two factors emerged regard­less of subgroups; Elegance and Extroversion factor. The first factor was found to be dominant, accounting for 60 percent of the total variance. The other accounted for just 11 percent. Multidimensional ANOVA (5-way, 3-way) was conducted to test the effect of the clothing variables against two factors identified from the factor analysis. Leg exposure was the most powerful variable affecting the impression of Elegance and Extroversion factor for all per. ceiver subgroups. Neck exposure had primary effect on the impression of Elegance, whereas it partially influenced that of Extroversion. Color of suit had only partial effect on the impression of Extroversion. Hypothesis I was partially supported from the findings above. The effect of perceiver's age and sex on impression by the function of clothing variables was tested by comparing the result between four subgroups. In forming an impression of the wearer's modesty, male college students were least affected by the manipulation of clothing variables, while middle aged males were affected most. In the female groups, there was no age difference and they fell between the male groups in the degree to which they were affected. Hypothesis II was supported only by age difference in two male groups, and by sex difference in two student groups.

The purpose of this study was to investigate the effect of food behavior on dietary food intake status and health condition based on research of food behavior and nutritional intake status of university students in the Chungnam area. The average age, height, and weight of the subject group were 22.1 years old, 174.2 cm, and 67.0 kg for the male students and 20.9 years old, 161.8 cm, and 53.4 kg for the female students, respectively. From the nutritional intake status data, the averaged daily energy intake of both groups, male and female, are lower than the dietary reference intake(KDRI), as 2,169.2 kcal and 1,846.2 kcal, males and females, respectively. The lipid intake ratio was higher than the dietary reference figure, and the carbohydrate intake ratio was determined to be in the proper range. Male students(54.6%) and female students(52.0%) of the entire subject group skipped a breakfast mainly due to insufficient time, and the time at which meals were consumed, was determined to be irregular generally. In a day, male and female students have a heavier dinner than lunch(p<0.05), respectively. Meat and fishes are preferred by the entire subject group, and the number of students, who do not eat carrot and mayonnaise(p<0.05), was determined to be the highest, of all foods surveyed. The averaged daily activity coefficient and the resting energy expenditure shows significant difference(p<0.001) between two groups; was 1.7 and 1.6 and the second was 1,404.3 kcal/day and 1,292.5 kcal/day for the male and female groups, respectively. As the number of attempting to reduce body weight(p<0.001), the amount smoking(p<0.001), or the frequency of drinking alcohol increases, BMI decreases. On the other hand, as body shape satisfaction increases, BMI increases also.
