<P>Ni/Cu two-step plating is a promising metallization technique because low contact resistance and improved contact adhesion can be achieved after the Ni annealing process. Also, narrow fingers, which are required for high-efficiency solar cells, can be formed by plating. However, the reliability of contact adhesion is still considered one obstacle to industrializing solar cells with plated metal contacts. In this experiment, the influence of ARC opening methods on plated contact adhesion was investigated because the roughnesses of the Si surfaces produced by using pico-second laser ablation and photolithography may be different. Also, the annealing process was conducted before and after plating Cu/Ag metal stacks. The sequence of the annealing can be significant for efficient production because plating is a wet process while annealing is a dry process. The contact adhesion was measured by using a peel-off test. The test was conducted on a 1.5-mm-wide by a 60 similar to 70- mm-long bus bar area. A 3.2-N/mm adhesion force was recorded as a highest average value along the bus bar.</P>

Nowadays, energy management and its optimization using smart devices are getting more attention due to their significant applications. Moreover, the applications used in these devices play a key role in developing smart cities that is only the way to solve urban problems. The potential of renewable energy sources like solar and wind power has been integrated in the smart grids to overcome the lack of supply via conventional fossil fuels and their environmental disputes that reduce operational cost. This review paper describes the significance of renewable power data that directly assists all the functions in smart cities such as the evolution of microgrids, renewable resources, energy forecasting, and power storage technologies. Furthermore, solar and wind power plants’ data with weather information as an additional cue is collected from different companies in South Korea. We aim to assist the researchers to develop artificial intelligence (AI)-based algorithms for power forecasting and establish its efficient management between suppliers and consumers.

Background and Aim: Irrespective of etiologies of peptic ulcer diseases (PUD), the most ulcers develop on the lesser curvature side of stomach including incisura and anterior wall of duodenal bulb. However, still no clear explanation why ulcers are prevalent in these areas has been given except some speculations including insufficient perfusion through abnormality in blood vessel, weak structural points or host characteristics. Here, we hypothesized that VEGF polymorphism can predict the susceptibility to peptic ulcer disease through deranged angiogenic activities. Methods: Based on several single nucleotide polymorphisms (SNPs) of vascular endothelial growth factor (VEGF) gene reported in literature search and their frequency studies done with Korean population, we performed the case-control study of 864 patients of chronic gastritis and gastric ulcer in 10 SNPs of VEGF gene including -2488 C/T, -634G/C, -7C/T, 3436G/C, 6112C/A, 6894C/T, 9374G/A, 9812C/T, 13128C/T, and 13553C/T, but of which results showed no statistically significant association between chronic gastritis and gastric ulcer. Results: We performed denatured high-performance liquid chromatography analysis to discover the novel SNP of VEGF gene, after which two novel SNPs of VEGF gene, -1780T/C and IVS-99 G/C, were identified, among which -1780T/C showed significant association between chronic gastritis and peptic ulcer disease, showing OR=2.93 on co-dominant analysis (p<0.001), OR=8.62 on dominant analysis (p<0.001), and OR=3.21 on recessive analysis (p<0.001). Promoter assay using site directed mutagenesis and in vitro angiogenesis assay showed repressed transcription of VEGF gene in gastric epithelial cells and defective tube formation in endothelial cells transfected with plasmid containing -1780C/C mutant of VEGF gene. Conclusion: Novel VEGF polymorphism, -1780T/C, is significantly associated with the predisposition to PUD after the exposure to etiologic risks.

Background/Aim: Many patients with lamivudine-resistant (LAM-R) chronic hepatitis B (CHB) had been treated by switching to entecavir (ETV) 1.0mg. Although rate of resistance to ETV (ETV-R) is reported high, current medical insurance system doesn`t pay-back for change from ETV to other agent in patients whose resistance to ETV was not identified. This study was aimed to stratify ETV therapy in LAM-R patients. Methods: One hundred and ten CHB patients who occurred LMV-R and received ETV 1.0mg up to 5 years were evaluated prospectively. At 12 months of switching to ETV, we divided subjects into non-detection group (HBV DNA<20 IU/mL) and detection group (HBV DNA≥20 IU/mL), which was subdivided into low viral load group (20≤HBV DNA<2,000 IU/mL) and high viral load group (2,000 IU/mL≤ HBV DNA). Virologic response rate (VR; HBV DNA<20 IU/mL) and ETV-R were evaluated as end point. Results: One hundred and ten patents were enrolled. The mean age was 45±11years, the proportion of male and HBeAgpositive patient was 71% (80/110) and 77% (85/110), respectively. The mean serum HBV DNA levels were 6.89±1.03, 3.26±1.81, 3.06±1.82, 2.49±1.53, 2.43±1.35 and 1.73±0.87 log10IU/ ml at baseline, month 12, 24, 36, 48 and 60, respectively. The VR (95% vs. 29%, P<0.001) was higher and ETV-R (10% vs. 54%, P=0.001) was lower in non-detection group than in detection group. The VR (27% vs. 29%, P=0.853) and ETV-R (45% vs. 57%, P=0.367) was not significantly different between low viral load and high viral load group. Resistance to ETV occurred at 26±10.3 months (median 24 months, 12-48 months) in detection group. Conclusion: Resistance rates were high in patients with detectable HBV DNA at 12 months of ETV therapy. Therefore, switching to or adding a potent nucleotide analogue (e.g. tenofovir) is warranted in LAM-R CHB patients whose HBV DNA is detected after 12 months of ETV therapy.
The Palatability of Cereal Based Nutritional Supplements in Cancer Patients
( Hyun Wook Baik ),( Mi Kyung Sung ),( Yu Sun Lee ),( Min Kyung Song ),( Yun Jung Bae ) 한국임상영양학회 2014 Clinical Nutrition Research Vol.3 No.1
Recently, it is reported that intervention of oral nutritional supplement improves the nutritional status of cancer patients, and the effectiveness is affected by the sensory preference of cancer patients on the oral nutritional supplement. However, the variety of oral nutritional supplement is extremely limited and the number of patient``s benefits from using the products are restricted mostly due to sensory dislikes. The objective of this study was to provide sensory preference score of trial manufactured products with different accessory ingredients to maximize the use of oral nutritional supplements. Cancer patients (n = 30) and age, sex-matched healthy volunteers (n = 30) participated in the sensory assessments (taste, flavor, viscosity, color and overall preference) of three types of oral supplements (cereal base, cereal base+herb and cereal base+fruit) and a control supplement product with scorched cereal flavor, a top seller in current Korean market. Results indicate that the cancer patients`` overall preference was significantly higher for the control supplement, and fruit added supplement was preferred over plain cereal and herb added products, although the difference was insignificant. However, there was no significant preference difference for the supplements among the control group for all sensory factors. These results suggest that cancer patients are more sensitive to sensory preferences compared to the control group, and the patients prefer the flavor of cooked cereal which is a staple food in Korea.

We report a case of a 6-month-old female who had had verrucous hemangioma since birth. The lesions were dark red, verrucous surfaced, hyperkeratotic papules on the right sole. A histopathological examination showed hyperkeratosis, papillomatosis, irregular acanthosis, lobular proliferation and dilatation of blood vessels in the deep dermis with a gap devoid of vessel proliferation in the mid dermis.

Endometrial stromal sarcoma (ESS) is a relatively rare form of uterine sarcoma. Endometrial stromal sarcoma (ESS) of the myometrium compose just 0.2% of uterine malignant tumors. Low-grade stromal sarcoma has extended beyond the uterus in 40% of cases at the time of diagnosis, but the extra-uterine spread is confined to the pelvis in two thirds of the cases. A few cases of extra-uterine endometrial stromal sarcoma have been reported in literature concerning the ovary and pelvis. We have experienced a Post-total hysterectomy with bilateral salpingooophorectomy retroperitoneal endometrial stromal sarcoma, so we report this case with a brief review of literature.
