We present a facile method for producing superhydrophobic nanograss-coated （SNGC） glass surfaces that possess both reduced reflectivity and self-cleaning properties at the air/glass interface. The refractive index of a CaF2 nanograss （NG） layer on a glass substrate, deposited by glancing angle vapor deposition, is 1.04 at 500 nm, which is the second-lowest value ever reported so far. The fluorinated NG layer gives rise to a high water contact angle （〉150°） and very efficient cleaning out of dust with water drops. Using the dual functionalities of the SNGC glass, we demonstrate superhydrophobic and antireflective organic photovoltaic cells with excellent power conversion efficiency.

EAFoC： Enterprise Architecture Framework Based on Commonality

引用

Journal of Computer Science & Technology 2006年第6期21卷 952-964页

作者： jin-woo Kim Ju-Hum Kwo young-Gab Kim Chee-Yang Song Hyun-Seok Kim Doo-Kwon Baik Department of Computer Science and Engineering Korea University 1 5-Ga Anam-Dong Sungbuk-Ku Seoul 136-701 Korea Department of Software Engineering Sang-Ju National University 386 Street Kajang-Dong Sang-Ju 742-711 Korea

The recent rapid development in information systems （ISs） has resulted in a critical need for integration and interoperability between heterogeneous ISs in various domains, using specific commonalities. However, stovepipe systems have been caused due to inconsistencies in planning IS architecture among stakeholders. So far, there has been no research on an enterprise architecture framework （EAF） that can satisfy with the coefficient factors of system architecture （SA） and enterprise architecture （EA）. This paper proposes a new EAF that can resolve the problems inherent in existing legacy EAFs and their features. EAFoC （Enterprise Architecture Framework based on Commonality） is based on commonality that can be satisfied as the coefficient factors in both SA and EA within a common information technology （IT） domain. Thus, it should be possible to integrate an established heterogeneous framework for each stakeholder＇s view. Consequently, the most important contribution of this paper is to establish the appropriate EAFoC for the development of consistent IS architecture, smooth communication among stakeholders, systematic integration management of diversified and complicated new IT technologies, interoperability among heterogeneous ISs, and reusability based on commonality with other platforms.

Creep and tensile properties of press molding joined GMT-sheets

引用

Transactions of Nonferrous Metals Society of China 2011年第A1期21卷 170-174页

作者： jin-woo KIM Dong-Gi LEE Center for NDE Iowa State University Department of Mechatronics Engineering Chosun University

GMT-sheet is used in automobile bumper with high rigidity and strength, and its joining strength is influenced by lap length, one of the joined molding conditions. Fracture strength was calculated by dividing fracture load with cross-sectional area. Total five repeated measurements were made to obtain the average value. Tensile test was conducted at room temperature for 10 specimens. In addition, the effect of compression ratio on creep and tensile performance during lap joined molding was discussed. With increasing lap length, the lap joining efficiency of GMT-sheet was increased. However, higher compression ratio reduced the joining efficiency. Creep test on GMT-sheet showed abrupt fracture without tertiary creep. This can be explained by the weak thermal resistance of the resin. If GMT-sheet was exposed to high temperature for a long time, it was easily failed by external force.

Duodenal variceal bleeding after balloon-occluded retrograde transverse obliteration: Treatment with transjugular intrahepatic portosystemic shunt

We report a case of duodenal varix bleeding as a long term complication of balloon occluded retrograde transvenous obliteration (BRTO), which was successfully treated with a transjugular intrahepatic portosystemic shunt (TIPS). A 57-year-old man was admitted to the emergency room suffering from melena. He had under-gone BRTO to treat gastric varix bleeding 5 mo before admission. Endoscopy and a computed tomography (CT) scan showed complete obliteration of the gastric varix, but the nodular varices in the second portion of the duodenum expanded after BRTO, and spurting blood was seen. TIPS was performed for treatment of duodenal variceal bleeding, because attempts at endoscopic varix ligation were unsuccessful. The post-operative course was uneventful and the patient was discharged without complications. A follow up CT scan obtained 21 mo after TIPS revealed a patent TIPS tract and complete obliteration of duodenal varices, but multinodular hepatocellular carcinoma had developed. He died of hepatic failure 28 mo after TIPS.

Effect of Zhubin(KI9) Acupuncture in Reducing Alcohol Craving in Patients with Alcohol Dependence:A Randomized Placebo-Controlled Trial

引用

Chinese Journal of Integrative Medicine 2015年第4期21卷 307-311页

作者： jin-Seong Lee Sung-Gon Kim Taek-Geun Jung woo young Jung Seong-Yeon Kim Department of Psychiatry Pusan National University Yangsan Hospital Biomedical Research Institute Pusan National University Hospital Jang-Cheon Korean Medicine Clinic Division of Management Information Science(S-YK) Dong-A University

Objective： To examine the effect of acupuncture on Zhubin （KI9） in reducing alcohol craving in alcohol-dependent patients. Methods： Twenty male alcohol-dependent patients were randomly assigned to two groups, a treatment group （10 cases, age 43.0 ± 6.8 years） and a placebo group （10 cases, age 44.5 ± 7.9 years）. The treatment group was treated with real needle acupuncture on Zhubin （KI9） twice a week for 4 weeks, and the control group was treated with placebo needle acupuncture. Both groups were given acupuncture treatment using Park Sham Device （PSD）. Alcohol craving was measured by the Visual Analogue Scale （VAS） before treatment to establish a baseline, and after 1, 2, and 4 weeks of treatment. Repeated measures ANOVA was used to determine the main and interaction effects of time and on the outcome measure （VAS）. Results： There was a significant effect of time on VAS score （dr=3, F=13.3, P〈0.01）. Main effect of group on VAS score was significant （df=1, F=10.9, P〈0.01） and the time × group interaction was also significant （df=3, F=4.7, P〈0.01）. Conclusions： Real-needle acupuncture therapy on Zhubin （KI9） showed effectiveness in reducing alcohol craving. These results strongly suggest the usefulness of acupuncture therapy on Zhubin （KI9） in preventing a relapse in alcohol dependent patients.

Ex situ aging effect on sulfonated poly(ether ether ketone) membrane:Hydration-dehydration cycling and hydrothermal treatment

引用

Journal of Energy Chemistry 2022年第7期31卷 583-592,I0014页

作者： Seung-young Choi Kyeong Sik jin Polymer&Materials Chemistry Department of ChemistryLund UniversitySE-22100Sweden Center for Hydrogen·Fuel Cell Research Korea Institute of Science and Technology(KIST)Seoul 02792Republic of Korea Pohang Accelerator Laboratory Pohang University of Science and Technology(POSTECH)PohangKyungbuk 37673Republic of Korea

Prolonged hydrothermal treatment for sulfonated poly(ether ether ketone) membranes induces mechanical degradation and developing hydrophilic-hydrophobic phase separation, simultaneously. The enhanced phase separation provides incremental proton conductivity to the membranes, whereas mechanical degradation drastically reduces device stability. On this basis, we describe here the effects of two different ex situ aging processes on sulfonated poly(ether ether ketone) membranes: hydrationdehydration cycling and prolonged hydrothermal treatment. Both aged membranes exhibited enhanced phase separation under the hydrated conditions, as characterized by small angle X-ray ***, when the aged membranes were dried again, the nanostructure of the membranes aged via the hydration-dehydration cycling was recoverable, whereas that of the membranes aged via prolonged hydrothermal treatment was irreversible. Furthermore, the two differently aged membranes showed clear differences in thermal, mechanical, and electrochemical properties. Finally, we implemented both aged membranes in fuel cell application. The sample aged via hydration-dehydration cycling maintained its improved cell performance, whereas the sample aged via hydrothermal treatment showed drastically reduced cell performance after durability test for 50 h.
