Objectives : The purpose of this study was to compare the social functioning between schizophrenic patients treated with olan-zapine and those with typical antipsychotics. Methods : Fifty-seven schizophrenic patients with acute exacerbation entered consecutively to olanzapine treatment (N=33) or typical antipsychotic treatment (N=24). The assessment of social functioning and symptoms were made at 3 time points : at the time of admission (baseline), 6 months and 12 months after starting medications. Social functioning and symptoms were examined using the Korean version of Social Adjustment Scale II-Revised Version (KSAS n-RV) and the Positive and Nega-tive Syndrome Scale (PANSS). Results : After 6-months and 12-months treatments, olanzapine treatment group showed significantly improved PANSS total scores (p=.02), Positive scores (p=.04), negative scores (p=.01), and KSAS II-RV total score (p=.004), instrumental role (p= .002), social leisure (p= .03), Personal well-being subarea scores (p= .02), compared with the scores of typical antipsy-chotic treatment group. Conclusion : Olanzapine was more effective than typical antipsychotics in reducing the severity of psychopathology and in improving some subareas of social functionings in patients with schizophrenia. The benefits of olanzapine on social functioning, although modest, may be important factor considering their accumulative effects for long-term treatment.

This report studied 31 male patients who were in one hospital in Kwangju or came to a prosthesis clinic and are 15 normal control group to analyze the gait characteristics according to the stump length in the prosthesis users with the unilateral below-knee amputations. The patient group was divided into a short stump subgroup of 13 patients and a long stump subgroup of 18 patients according to the stump length, the control group was randomly sampled from 15 males who have similar age, height and weight to the experimental group. The results of analysis are summarized as follows. 1. There were no significant statistical differences of the general characteristics between patient and control groups and there was no difference of characteristics by patient groups except the mean gait distance a day. 2. Of 33 patients with amputation, 18 patients (57.8%) had phantom pain and 25 cases (80.6%) had neuroma. 3. Gait velocity, stride length of the affected side, step length of the sound side and base support among gait characteristics show a significant difference according to the stump length in the state excluding the effects of other factors (p<05) and the group with long stump showed closer gait characteristics to normal persons than those with short stumps. In conclusion, among the patients of unilateral below-knee amputations, the stump length affects the gait characteristics such as gait velocity, stride length, step and base of support and it is found that as the stump length gets longer, it shows the similar characteristics to gait characteristics of normal persons and long unilateral below-knee amputation can secure better gait characteristics.

A multitude of modifications strategy of ZnFe₂O₄ nanorod photoanodes for enhanced photoelectrochemical water splitting activity

Kim, Ju Hun,Jang, Youn Jeong,Choi, Sun Hee,Lee, Byeong Jun,Kim, Jeong Hun,Park, Yoon Bin,Nam, Chang-Mo,Kim, Hyun Gyu,Lee, Jae Sung The Royal Society of Chemistry 2018 Journal of Materials Chemistry A Vol.6 No.26

<P>Numerous modifications strategies are applied to spinel ZnFe2O4 nanorods with a band gap energy of ∼2.0 eV to enhance their activity as a photoanode for photoelectrochemical (PEC) water splitting. First, hybrid microwave annealing (HMA) imparts high crystallinity to ZnFe2O4 nanorods, while preserving the formed nanostructure and maintaining high electric conductivity of F:SnO2 (FTO) substrate. This is in contrast to conventional thermal annealing (CTA) at 800 °C that causes aggregation of ZnFe2O4 and degradation of FTO. Second, insertion of a TiO2 underlayer blocks charge recombination at the FTO/electrolyte interface and serves as a source of Ti doping. Third, hydrogen treatment yields oxygen vacancies that increase charge carrier density and cause surface passivation. Last, a NiFeOx co-catalyst promotes hole injection into the electrolyte to improve catalytic water oxidation activity. These synergistic modifications lead to enhanced photocurrent density from 0.025 mA cm<SUP>−2</SUP> at 1.23 VRHE for pristine ZnFe2O4 nanorods prepared by CTA to 0.92 mA cm<SUP>−2</SUP> for a fully modified HMA photoanode: a 37-fold increase in photocurrent density. There is also a cathodic shift of the onset potential down to 0.62 VRHE. The multiple modifications enhance bulk charge separation efficiencies from mere 2% to 30% and surface charge separation efficiency from 40% to 80%.</P>

Byeong-Chan Park(박병찬),Jin-Sung Kim(김진성),Yu-Hyeon Won(원유현),Young-Mo Kim(김영모),Seok-Yoon Kim(김석윤) 한국컴퓨터정보학회 2019 韓國컴퓨터情報學會論文誌 Vol.24 No.1

One of critical issues in dealing with 360-degree realistic contents is the performance degradation in searching and recognition process since they support up to 4K UHD quality and have all image angles including the front, back, left, right, top, and bottom parts of a screen. To solve this problem, in this paper, we propose an efficient search and comparison method for 360-degree realistic contents. The proposed method first corrects the distortion at the less distorted regions such as front, left and right parts of the image excluding severely distorted regions such as upper and lower parts, and then it extracts feature points at the corrected region and selects the representative images through sequence classification. When the query image is inputted, the search results are provided through feature points comparison. The experimental results of the proposed method shows that it can solve the problem of performance deterioration when 360-degree realistic contents are recognized comparing with traditional 2D contents.

<P>Reduced therapeutic efficacy of sorafenib, a first-generation multikinase inhibitor, is often observed during the treatment of advanced hepatocellular carcinoma (HCC). Emodin is an active component of Chinese herbs, and is effective against leukemia, lung cancer, colon cancer, pancreatic cancer, and HCC; however, the sensitizing effect of emodin on sorafenib-based HCC therapy has not been evaluated. Here, we demonstrate that emodin significantly improved the anti-cancer effect of sorafenib in HCC cells, such as HepG2, Hep3B, Huh7, SK-HEP-1, and PLC/PRF5. Mechanistically, emodin inhibits sterol regulatory element-binding protein-2 (SREBP-2) transcriptional activity, which suppresses cholesterol biosynthesis and oncogenic protein kinase B (AKT) signaling. Additionally, attenuated cholesterol synthesis and oncogenic AKT signaling inactivated signal transducer and activator of transcription 3 (STAT3), an oncogenic transcription factor. Furthermore, emodin synergistically increased cell cycle arrest in the G1 phase and apoptotic cells in the presence of sorafenib. Animal models xenografted with HepG2 or SK-HEP-1 cells also showed that the combination of emodin and sorafenib was sufficient to inhibit tumor growth. Overall, these results suggested that the combination of emodin and sorafenib may offer a potential therapy for patients with advanced HCC.</P>

Kim, Byeong-Soo,Lim, Kang-Uk,Baek, In-Seon,Kim, Min-Kyoung,Kang, Hye-Min,Nam, Gi-Jeong,Lee, Myung-Mo korean Academy of Physical Therapy Rehabilitation 2019 Physical therapy rehabilitation science Vol.8 No.1

Objective: The aim of this study is to investigate the effects of whole body vibratory stimulation on muscle strength, balance, and fall efficacy among super-aged women. Design: Randomized controlled trial. Methods: Twenty-eight super-aged women over 80 years of age were assigned to either the experimental group (n=14) and control group (n=14). The experimental group received an exercise program that used the whole body vibratory stimulation with a frequency of 30 Hz and amplitude of 3 mm, and the control group received an exercise program without vibratory stimulation. Intervention was provided for 4 weeks, 3 sessions per week, and 30 minutes per session. In order to measure lower extremity muscle strength the 30-second chair stand test (CST) was used. The Berg Balance Scale (BBS) was used to measure dynamic balance. Static balance was measured by tracking the path length, velocity, and area of the center of pressure (CoP). The Falls Efficacy Scale (FES) was used to measure the subjects' fear of falling. Results: Both the experimental and control group demonstrated statistically significant increase in muscle strength, dynamic balance, and fall efficacy (p<0.05). Only the experimental group showed significant improvements in static balance before and after the intervention (p<0.05). The experimental group showed significantly greater improvements in CST, BBS, and CoP (path length, velocity) than control group (p<0.05). Conclusions: Whole body vibratory stimulation exercise is shown to be a safe and appropriate physical therapy intervention method to enhance muscle strength, balance, and fall efficacy of super-aged women.
