  • The purpose of this study was to evaluate the effect of maternal nutritional status and health behaviors on the concentrations of minerals (Zn, Fe, Ca) and the immunological substances (lactoferrin, sIgA, Iysozyme) in breast milk. Breast milk was collected from 193 healthy Korean women from obstetric clinics and postpartum care centers in Seoul. : 99 colostrum (1 - 5 days postpartum), 33 transitional milk (6 - 10 days postpartum), 61 mature milk (11 - 50 days postpartum). The concentrations of minerals and immunological substance were highest in colostrum and decreased with lactational period. Concentrations of Zn and Fe reduced significantly from colostrum to mature milk, however, Ca concentration stayed constant throughout the lactational period. Contents of lactoferrin, sIgA, and lysozyme were significantly lower in mature milk than in colostrum. Mother's nutritional status, assessed by prepregnancy BMI, had an effect only on colostrum, but not on transition and mature milk. Fe concentration of colostrum was significantly lower in underweight (prepregnancy BMI < 18.5) than in overweight mothers (prepregnancy BMI $\geq$ 23.0). Also lower tendency was observed for sIgA and lysozyme contents, even though the difference was not statistically significant. Pregnancy weight gain had no effect on the breast milk component. Since nutritional factors had some effect on colostrum, the health behaviors of mothers providing colostrum were assessed. The mother's behavior of smoking, drinking, morning sickness, parity, disease, nutrient supplement use had no significant effect on the breast milk component, however, Zn, sIgA, and lysozyme were the somewhat affected components by maternal health behavior.

  • The definitive correction of secondary lip nasal deformities is a great challenge for plastic surgeons. To rectify the secondary lip nasal deformities, various procedures and its modifications have been reported in many centers. However, no universal agreement exist to correct the various components of secondary nasal deformities. The secondary nasal deformity of the unilateral cleft lip has its own characteristic abnormalities including the retroplaced dome of the ipsilateral nasal tip, hooding of the alar rim, a secondary alar-columellar web, short columella, depressed alar base and so forth. Among these components of secondary nasal deformity, maxillary hypoplasia, especially in the area of piriform aperture, and alveolar bone defect can make the alar base depressed, which in turn, leads to wide and flat nasal profile, obtuse nasolabial angle coupled with subnormal nasal tip projection in aspect of aesthetic consideration. Moreover, the maxillary hypoplasia contributes to reduced size of the nasal airway in combination with other component of external nasal deformity and therefore the nasal obstruction may be developed functionally. Therefore, the current authors have performed corrective rhinoplasty with the augmentation of alar base with various methods which include rearrangement of soft tissue, vertical scar tissue flap and use of allogenic or autologous materials in 42 patients between 1998 and 2003. The symmetric alar base could be achieved, which provides the more accurate evaluation and more appropriate management of the various component of any coexisting secondary nasal deformity. In conclusion, the augmentation of alar base, as a single procedure, is a basic and essential to correct the secondary lip nasal deformities.

  • Background: Dialysis patients are prone to having disabilities. We aimed to evaluate the association between disability and various clinical outcomes in Korean dialysis patients. Methods: This study consisted of 1,615 dialysis patients from 27 centers. We evaluated disability by using four questions on the activities of daily living (ADLs) concerning whether help was needed for feeding, dressing/undressing, getting in/out of bed, or taking a bath/shower. We divided the patients into three groups: no disability (Non-D, none of the four ADL domains required help; n=1,312), mild disability (Mild-D, one ADL domain required some/full help; n=163), or moderate to severe disability (MS-D, two or more ADL domains required some/full help; n=140). We evaluated falls, frailty, health-related quality of life (HRQoL), mortality, and hospitalization. Results: The numbers of participants with a fall during the last 1 year were 199 (15.2%), 42 (25.8%), and 44 (31.4%) in the Non-D, Mild-D, and MS-D groups, respectively (p<0.001). The numbers of participants with frailty in the Non-D, Mild-D, and MS-D groups were 381 (29.0%), 84 (51.5%), and 93 (66.4%), respectively (p<0.001). In both univariate and multivariate analyses, the physical component scale and mental component scale scores decreased as the grade of disability increased (p<0.001 for both scores). Hospitalization-free survival rate at 500 days was 64.2%, 56.7%, and 51.1% in the Non-D, Mild-D, and MS-D, respectively (p=0.001 for trend). Patient survival rate at 500 days was 95.3%, 89.5%, and 92.3% in the Non-D, Mild-D, and MS-D, respectively (p=0.005 for trend). Conclusion: Disability was associated with falls, frailty, HRQoL scales, and survival trends in Korean dialysis patients.

  • The anchor-free object detector CenterNet regards the object as a center point and predicts it based on the Gaussian circle region. For each object's center point, CenterNet directly regresses the width and height of the objects and finally gets the boundary range of the objects. However, the critical range of the object's center point can not be accurately limited by using the Gaussian circle region to constrain the prediction region, resulting in many low-quality centers' predicted values. In addition, because of the large difference between the width and height of different objects, directly regressing the width and height will make the model difficult to converge and lose the intrinsic relationship between them, thereby reducing the stability and consistency of accuracy. For these problems, we proposed a center point prediction method based on the Gaussian elliptic region and a size component regression method based on the small solution space. First, we constructed a Gaussian ellipse region that can accurately predict the object's center point. Second, we recode the width and height of the objects, which significantly reduces the regression solution space and improves the convergence speed of the model. Finally, we jointly decode the predicted components, enhancing the internal relationship between the size components and improving the accuracy consistency. Experiments show that when using CenterNet as the improved baseline and Hourglass-104 as the backbone, on the MS COCO dataset, our improved model achieved 44.7%, which is 2.6% higher than the baseline.

  • It is well established that health care workers (HCWs) have a considerably higher risk of occupationally acquired tuberculosis (TB). To reduce the transmission of TB to HCWs and patients, TB infection control programs should be implemented in health care settings. The first and most important level of all protection and control programs is administrative control. Its goals are to prevent HCWs, other staff, and patients from being exposed to TB, and to reduce the transmission of infection by ensuring rapid diagnosis and treatment of affected individuals. Administrative control measures recommended by the United States Centers for Disease Control and Prevention and the World Health Organization include prompt identification of people with TB symptoms, isolation of infectious patients, control of the spread of the pathogen, and minimization of time spent in health care facilities. Another key component of measures undertaken is the baseline and serial screening for latent TB infection in HCWs who are at risk of exposure to TB. Although the interferon-gamma release assay has some advantages over the tuberculin skin test, the former has serious limitations, mostly due to its high conversion rate.

  • As the idea and function of the 'Model House' alters, so does the name - 'Housing Exposition' or 'Housing Cultural Center'. Its function Is not only to show and sell but to educate, promote and show culture. It works as a 'communication ground' about house. With the growing number of the Housing Cultural Center and the importance of function, major construction companies are building it competitively to connect the relationship with clients by expanding service. However, despite the necessity of 'Housing Cultural Center' is increasing, function and component of the Housing Cultural Center are yet defined and also specific direction of design, consumer services and programs are not properly established. Also, they are promoting and selling in lots only for a limited period which have problem in clients to participate and know about the characteristics of each companies promotion. Most of Housing Cultural Centers are similar in concept, shape, color use. The purpose of this research is to analyze the Housing Cultural Center with spacial and visual elements that comprise Housing Cultural Center, and study identity factors, distinct characteristics and build identity of the Housing Cultural Center. Ultimately, companies need to put forth to make difference in their own identity and apply it effectively in order to firmly establish identity.

  • In order to precisely determine the vertical displacements of CORS antenna phase centers caused by their replacement, intensive research has been carried out in this paper throughout processing GPS measurements made before and after the events. After applying the estimated displacement in the data processing, results show that coordinate repeatability of the vertical component is able to be 7.9mm on average. Comparing with results (e.g., 23.5mm) without applying the displacement, it was possible to conclude that these accuracies are significantly improved, which is equivalent to those before the event of the replacement.
