Namgoong Sik,Baik Seunghee,Han Seung-Kyu,Son Ji-Won,Kim Jae-Yeon 대한의학회 2023 Journal of Korean medical science Vol.38 No.21
Background: The existing literature has comprehensively examined the benefits of specialized wound-care services and multidisciplinary team care. However, information on the development and integration of wound-dressing teams for patients who do not require specialized wound care is scarce. Therefore, the present study aimed to elucidate the benefits of a wound-dressing team by reporting our experiences with the establishment of a wounddressing team. Methods: The wound-dressing team was established at Korea University Guro Hospital. Between July 2018 and June 2022, 180,872 cases were managed for wounds at the wounddressing team. The data were analyzed to assess the types of wounds and their outcomes. In addition, questionnaires assessing the satisfaction with the service were administered to patients, ward nurses, residents/internists, and team members. Results: Regarding the wound type, 80,297 (45.3%) were catheter-related, while 48,036 (27.1%), 26,056 (14.7%), and 20,739 (11.7%) were pressure ulcers, dirty wounds, and simple wounds, respectively. In the satisfaction survey, the scores of the patient, ward nurse, dressing team nurse, and physician groups were 8.9, 8.1, 8.2, and 9.1, respectively. Additionally, 136 dressing-related complications (0.08%) were reported. Conclusion: The wound dressing team can enhance satisfaction among patients and healthcare providers with low complications. Our findings may provide a potential framework for establishing similar service models.

In this investigation, 34 structurally different flavonoids including derivatives of chalcone, flavanone, flavan-3-ol, flavone, flavonol, and their glycosides were evaluated for in vitro suppression of mitogen-induced lymphocyte proliferation and mixed lymphocyte culture from mouse spleen. Flavonoids, mainly derivatives of flavone and flavonol, clearly demonstrated the suppressive effects on lymphocyte proliferation at higher than 10^(-6) M depending on the structures of flavonoid molecules, although their suppressive activities were less than that of cyclosporin A or prednisolone. Various glycosidic substitutions to A- and/or C-ring of the flavonoid aglycones were found to eliminate the suppressive activities of their aglycones, regardless of sugar compositions and positions of substitutions. In concanavalin A-induced lymphocyte proliferation, derivatives of flavone and flavonol having 2, 3-unsaturation and at least 1 hydroxyl group showed the suppressive activity. In lipopolysaccharide-induced lymphocyte proliferation, only myricetin was active among flavonoids tested at the concentrations up to 10^(-5) M. In mixed lymphocyte culture, some derivatives of flavone and flavonol with 2, 3-unsaturation were active and especially flavone derivatives showed the higher suppressive activities than those of the flavonol derivatives.

Congenital absence of the portal vein (CAPV) is a rare venous malformation in which mesenteric venous blood drains directly into systemic circulation. Herein, we report a case of pediatric deceased donor liver transplantation (DDLT) for symptomatic CAPV with whole liver graft from a hepatitis B surface antigen (HBsAg)-positive donor. A 4-year-old boy suffered from CAPV and secondary portal hypertension. He was also diagnosed with DiGeorge syndrome and heart anomalies. After waiting for 4 months, a 5-year-old donor weighing 19 kg with positive HBsAg was allocated to this 4-year-old patient weighing 15 kg. Recipient operation was performed according to the standard procedures of pediatric DDLT. Portal vein reconstruction was performed using interposition of a vascular homograft conduit to the superior mesenteric vein-splenic vein confluence. The patient recovered uneventfully from DDLT. He has been administered with lamivudine to prevent hepatitis B virus infection. This patient has been doing well for 5 years after DDLT without growth retardation. In conclusion, CAPV patients can have various vascular anomalies, thus combined vascular anomalies should be thoroughly assessed before and during liver transplantation operation. The most effective reconstruction techniques should be used to achieve satisfactory results following liver transplantation.
Design of cyclotron magnet with tenth harmonics for accelerator mass spectrometry

In this study, we developed a carbon-beam cyclotron for accelerator mass spectrometry (AMS). A cyclotron magnet for AMS was developed for particle acceleration systems using cyclotrons rather than the tandem accelerator used in conventional accelerator mass spectrometry systems. Design parameters were selected for the development of cyclotrons for AMS, and the magnetic feld design and equilibrium orbit (EO) analysis beam trajectory were analyzed using the Cyclone and CST Microwave Studio. Additionally, by measuring the magnetic feld of the manufactured cyclotron, magnetic feld optimtableization was performed through shimming, and the beam trajectory was verifed based on the measurement results. The cyclotron magnet was designed with a mass resolution of 2890, with harmonic 10 and turn number 92. The minimum turn separation was optimized at 2 mm to reduce the loss caused by the collision of the beam during acceleration. This cyclotron for AMS could accelerate the 12C−, 13C−, and 14C− particles at 40 keV to obtain a beam of 400 keV.

<P><B>Abstract</B></P> <P>In the development of display devices, a color filter is still considered an indispensable component. For a thinner display panel, the thickness of the color filter also needs to be decreased. However, if the thickness of the color filter is reduced, the color properties, including the color purity and color gamut are simultaneously diminished. Therefore, introduction of new colorants is needed to lower the thickness without diminishing the color performance. In this study, four phthalocyanine green dyes were synthesized for use in color filters. The molecular geometry and absorption properties were predicted by density functional theory (DFT) and time-dependent DFT, and UV-Vis spectroscopy was employed to measure the optical properties. The thermal stabilities of the dyes were examined by thermogravimetric analysis. A dye with suitable solubility and color properties was adopted in the color filter, and the optical properties and thickness of the dye-based color filter were compared to those of the pigment-based color filter. The chromatic performance and thickness of the color filter were determined by color spectrometry and Alpha step, respectively. Finally, we confirmed that the dye could enable the decrease in the thickness of the filter and provide a superior color property.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Chloro- substituted (α positions) zinc phthalocyanine (Dye 3b) possessed a saddle core structure. </LI> <LI> The enhancing bulkiness inhibits the π-π stacking of the phthalocyanine molecules, thus increasing solubility. </LI> <LI> The dye decreases a thickness of color filter by 20%, owing to its higher color strength than that of pigments. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
Analysis of the Traditional Setting-up as an Application for Spatial Composition
NamGoong, Sun,Lee, Yu-Ri Korea Furniture Society 2010 한국가구학회지 Vol.21 No.3
Recently, there is a new issue, among the contemporary people, for new life style, such as green design and well being. This trend brought up the necessity that there should be alternatives for interior spatial design. In order to catch up with these new issues, the new convenient and environment friendly methods are in need. Space composition using setting-up is skill that can express both the structural aspect and esthetic because it represents traditional beauty into the contemporary age through the structural rigidity and formal beauty. Also the lumber, as main materials for setting up, is in line with well being life style and environment friendliness. The construction of structure by setting-up has advantages in terms of the reuse and the convenience in that the construction of structure is adjustable according to environment. And setting-up has enough plasticity not only because of its own role as linking the objects but also because of being framed by itself. Therefore setting-up will be a design element, if it is expressed outward. Thus, this study aims to give a guide line about how to apply the result from the evaluating that "what is the most suitable setting-up" and "what is the most suitable detail setting-up", based on that structural rigidity, decorativeness and the ease of works. As a result of evaluation, the most excellent types of setting-up in terms of structural rigidity are "Jangbu" and "Panjae" and "Yeongui". The most excellent types of setting-up in terms of decorativeness are "Panjae" and "Yeongui", and the most excellent type of the ease of work is "Mat". And also the most applicable detail setting-up for the utilization of spatial composition is proposed.
