Background: Spontaneous recovery of severe alopecia areata is rare and the condition is difficult to treat. Objective: The aim of this study is to investigate and compare the effects and safety of steroid pulse therapy between oral and intravenous administrations between 1999 and 2010 at the Department of Dermatology, National Cheng Kung University Hospital. Methods: Data were retrospectively retrieved. A satisfactory response was defined as more than 75% hair regrowth in the balding area. Results: A total of 85 patients with more than 50% hair loss were identified and treated, with an overall satisfactory response rate of 51.8%. The mean follow-up time was 37.6 months, with a relapse rate of 22.7%. Patients with alopecia areata (hereafter, AA) of recent onset within one year showed higher response rates (p< 0.001) and lower relapse rates compared to patients with AA persisting for more than 1 year. Further, even in patients with alopecia totalis, alopecia universalis or ophiasis type, early treatment resulted in a satisfactory response rate of 47% among the treated patients. In general, oral therapy was as effective and well-tolerated as intravenous therapy. Conclusion: The response rate is determined by disease severity and time of intervention, not by the administration form of steroid pulse therapy. Oral steroid pulse therapy can be considered as the first-line treatment for patients with severe AA of recent onset within one year. (Ann Dermatol 25(4) 471∼474, 2013)

Transcranial direct current stimulation (tDCS), a non-invasive neuromodulation technique, has been increasingly used to treat bipolar depression. Researchers recently noticed the risk of tDCS-emergent mania/hypomania in depressed patients and started to evaluate this risk by launching a meta-analysis. Here we present a female with bipolar II depression who rapidly developed hypomanic switching during bifrontal tDCS.

In this paper, we get new contraction-proximal point algorithms for solving the unconstrained convex optimization problems. We also get the relative strong convergence under some conditions. It also extends the use of already existing algorithms.
Effects of Clogging on Settlement Predictions of Ground Improved with Stone Columns
Pei Tai,Chao Zhou 대한토목학회 2019 KSCE JOURNAL OF CIVIL ENGINEERING Vol.23 No.9
Clogging of stone column (i.e., the mixture of column material and surrounding soil) is widely reported as well as its hindrance effect on the consolidation rate of soft ground improved with stone columns, however, its influence may be more complicated in settlement estimations. In this study, a modified consolidation model is proposed for making predictions of settlement with consideration of clogging. Its influence on permeability and compressibility is included while both radial and vertical flow in stone column are taken into account. Parametric studies reveal that the consolidation rate will be largely impeded if the permeability of clogged column drops below that of surrounding clay. The short-term settlement is lower mainly because of the reduction of permeability. On the contrary, the long-term settlement becomes larger due to an increase in compressibility. This finding implies that the final settlement may be underestimated if the clogging effects are not incorporated even when early field observations are available, as supported by a design example.

We present here the case of a 40-year-old woman with a greater than 10 year prior history of bilateral breast silicone injection and saline bag implantation. Bilateral palpable breast nodules were observed, but the ultrasound scan was suboptimal and the magnetic resonance imaging showed no gadoliniumenhanced tumor. The 18F-FDG PET/CT scan showed a hypermetabolic nodule in the left breast with a 30% increase of 18F-FDG uptake on the delayed imaging, and this mimicked breast cancer. She underwent a left partial mastectomy and the pathology demonstrated a siliconoma.
Psychographics and Destination Choice in Taiwan Media Tourists
( Pei Hsun Hung ),( Chih Liang Chao ) 한국문화관광학회 2013 문화관광연구 Vol.15 No.1
Film or movie may cause an increase in visitor numbers at cultural tourism site, due to generate and sustain interest in a destination by having been exposed repeatedly to these cultural things. However, researchers have well known that demographic and socio-economic attributes alone are not enough in understanding vacation destination choices. Therefore, psychographics, emphasized by Plog in 1974, was defined as different destination attracted different personality characteristics and can be a predictor of destination choice. The purpose of this study was to investigate the evidences related to the relationships between psychographic and destination choice from the media tourists. As an example of the most popular 2011 Taiwanese movie “Seediq Bale”, a historical event related to the conflict between ethnic groups, two tourism sites related to the movie were selected as study areas and distributed the questionnaire. The results from exploratory factor analysis show that there were four main psychographic characteristic. Moreover, all the respondents have been clustered as four groups from their main psychographic characteristic. The results found the constructs of psychographic characteristic group has significant differences across two tourism destinations. The results indicated qualified support for Plog`s psychographic model within the media tourists. Future suggestions and management issues have been provided based on site level.

The surface of self-made MoS2 nanosheets with five-layer structure was successively decorated by zinc borate (ZB) nanoparticles with coordination enhancement on the tribological performance and modified by three types of modifiers for improving dispersivity in oil. A series of characterizations determined the chemical modification and composite structure of the ZB/MoS2 nanocomposites. The tribological properties of the chemically capped ZB/MoS2 nanocomposites were extensively examined on a ball-on-ball wear tester. The average friction coefficient and average wear scar diameter of the OA-ZB/MoS2-based oil dropped by about 25.2% and 52.2%, and furthermore the extreme pressure performance increased by about 15.2% compared to oil.
