The temperature dependence of $Na^+-dependent$ succinate uptake was studied in brush border (BBMV) and basolateral (BLMV) membrane vesicles isolated from the rabbit kidney cortex. The succinate uptake was markedly altered by temperature in a similar fashion in both membranes. The temperature dependence was characterized by a nonlinear Arrhenius plot with a break point at 22 and $25^{\circ}C$ for BBMV and BLMV, respectively. The activation energy was 3.91 and 17.09 kcal/mole at above and below the break point respectively, far BBMV; 2.65 and 14.05 kcal/mole, respectively, for BLMV. When temperature increased f개m 20 to $35^{\circ}C$, the Vmax of succinate transport increased from $3.49{\pm}0.11\;to\;5.90{\pm}0.86\;nmole/mg/5\;sec$ for BBMV and from $2.86{\pm}0.25\;to\;3.63{\pm}0.32\;nmole/mg/5\;sec$ for BLMV, with no change in Km in both membranes. These results suggest that renal dicarboxylate transport is similarly sensitive to a change in membrane physical state in BBMV and BLMV.

Purpose: The aim of this study was to evaluate the effects of the group therapy on psychological symptoms and quality of life of patients with early stage breast cancer. Methods: This study was performed on 16 breast cancer patients who completed treatments. The total group therapy program involved a weekly session of 2-3 hours, for 16 weeks. The group therapy sessions were given to women in the oncology department by a clinical psychologist and also given training sections by the different professional teams. All the required assessments for the study were performed after and before 16 week group therapy intervention. Results: Initially we had taken 21 women but 16 participated in all therapy programs and submitted questionnaires. The mean age was 47.8 years. There were significant differences between before and after group therapy program. Anxiety, depression, and distress showed significant improvements. Hopelessness scale was detected at the border of significance. There was no change in sleep problems and quality of life. According to the analysis of correlation, considering the age factor and year of diagnosis, there was found no statistically significant relationship between anxiety, distress, depression, hopelessness, sleeplessness, and quality of life. Conclusions: This pilot study demonstrated that brief, predominantly group therapy is feasible for patients with breast cancer and, also it may be helpful to cope with emotional and physical distress.

Most of the research in the area of wireless communications exclusively relies on simulations. Further, it is essential that the mobility management strategies and routing protocols should be validated under realistic conditions. Most appropriate mobility models play a pivotal role to determine, whether there is any subtle error or flaw in a proposed model. Simulators are the standard tool to evaluate the performance of mobility models however sometimes they suffer from numerous documented problems. To accomplish the widely acknowledged lack of formalization in this domain, a Coloured Petri nets (CPNs) based random direction mobility model for specification, analysis and validation is presented in this paper for wireless communications. The proposed model does not suffer from any border effect or speed decay issues. It is important to mention that capturing the mobility patterns through CPN is challenging task in this type of the research. Further, an appropriate formalism of CPNs supported to analyze the future system dynamic status. Finally the formal model is evaluated with the state space analysis to show how predefined behavioral properties can be applied. In addition, proposed model is evaluated based on generated simulations to track origins of errors during debugging.

The paper aims to explore the factors affecting potential users of international bank cards in Vietnam. With milestones treaties being signed CPTPP and EVFTA, Vietnam is now exposing itself to the international open environment. Bank card market is at the core of this wind of change, and that is the reason for us to research the intention to use international bank cards. Given that the decision to choose international bank cards could either be the switch from domestic cards or adopting a brand new card, we develop some specific constructs to reflect that consideration, specifically PE and PD, asides from traditional constructs used in TPB and TAM frameworks. The analysis work is conducted using PLS-SEM approach. Our findings reveals that most of our proposed hypotheses are supported, in which SN plays the most important direct role to INT, while total effect of PU on INT is similar to that of SN. The newly introduced PD negatively and significantly impacts INT, and PE also has a positive impact on INT. The findings suggest that overall, it is important for bank card issuers to have a balance approach to the market, with focus on increasing usefulness and reducing potential disadvantages of international bank cards.

The purpose of this study was to evaluate the therapeutic effect of occlusal stabilization splint on the clinical symptoms and the condylar movement in patients with Temporomandibular Disorders(TMD). For the study, 15 TMD patients treated with stabilization splint and followed up were selected. The age of them was from 18 to 65 years and the mean period of treatment was 2.9 months. The author examined signs and symptoms of TMD according to Dr. Friction's evaluation from and recorded the condylar paths with Denar pantronic before and after splint therapy. The obtained results were as follows : 1. On the first visit, 11 patients(73.3%) showed muscle tenderness on palpation and the frequency was lateral pterygoid, masseter, medial pterygoid, temporalis, sternocleidomastoideus in the order named. 2. Occlusal stabilization splint was more effective in pain relief(100%) than in other dysfunction improvement(85.7%) 3. The amount of maximum opening increased from 37.1㎜ to 42.2㎜, but those of protrusion and laterotrusion changed little. 4. Pan. PRI scores decreased from 32.9 to 21.8, which meant improved reproducibility of mandibular border movements, and the group with sever dysfunction category showed more decrease in score than the group with moderate or slight dysfunction category.

For the Palestinians, what is the impact of the Arab Spring? The revolution not only dislodged Mubarak from the presidency, but also changed Egyptian policy regarding Palestinians in Gaza. New Egyptian diplomacy has encouraged Hamas and Fatah, which had been in dispute, to seek reconciliation and has loosened the border control on humanitarian grounds. We focus on Palestinian voting attitudes in the wake of the Arab Spring. Despite the vast quantity of literature written about Palestinian politics since the first decade of the millennium, we know little about the determinants of Palestinian attitudes toward the divided governments in the West Bank and the Gaza Strip. The Fatah government, in the West Bank, increased in popularity after submitting a request for UN recognition of Palestinian statehood. In Gaza, the Hamas government lost popularity because of mismanagement but won support through the success of its prisoner swap deal with Israel. However, evaluation of the ruling party does not depend only on one-time events. This research attempts to measure the impact of policy change in Gaza after the Arab Spring. We provide an account of our research on Palestinian attitudes toward the divided governments based on two sets of the original survey data conducted in May 2009 and June 2012. The paper sheds light on Palestinian attitudes and makes clear the effects of "democratization" in the Middle East and the effects of regional context factors on the occupied Palestinians.

The purpose of this paper is to clarify the aesthetic characteristics of splatter films' make-up. Splatter films are one of horror movies that consist of gore and excessive violence. These represent the cruelty with the victims' physical damages made by special effect make-up. Splatter make-up is classified into the trickle of blood, the cutting of body, and the exposure of the inner parts of body, and changes a fake into a fact with reality. The aesthetic characteristics of splatter make-up were shown in the uncanny, the abjection and the irony. The uncanny which is strange and displeasure feeling is presented by the fragmentation of body, and the living of nonliving thing. The abjection means humble image, and the concept of border or ambiguity. The former is expressed by the matters of body's secretion and excretion. The latter is shown by the use of blood(the life and death) and corpses(the human and inhuman), and animatronics(the human and instruments). The irony which is a sense of humor caused by conflict between external appearance and reality. This is represented by comics induced by discord between excessive violence and make-up tricks, and the brutality and the weakness.

The General Packet Radio Service (GPRS) is being deployed by GSM network operators world-wide, and promises to provide users with “always-on” data access at bandwidths comparable to that of conventional fixed-wire telephone modems. However, many users have found the reality to be rather different, experiencing very disappointing performance when, for example, browsing the web over GPRS. In this paper, we examine the causes, and show how unfortunate interactions between the GPRS link characteristics and TCP/IP protocols lead to poor performance. A performance characterization of the GPRS link-layer is presented, determined through extensive measurements taken over production networks. We present measurements of packet loss rates, bandwidth availability, link stability, and round-trip time. The effect these characteristics have on TCP behavior are examined, demonstrating how they can result in poor link utilization, excessive packet queueing, and slow recovery from packet losses. Further, we show that the HTTP protocol can compound these issues, leading to dire WWW performance. We go on to show how the use of a transparent proxy interposed near the wired-wireless border can be used to alleviate many of these performance issues without requiring changes to either client or server end systems.

The study investigates the association between the effectiveness of the board of directors and the likelihood that a company receives a modified audit opinion (as a measure of the quality of companies' external financial reporting) in Malaysia. The sample companies were extracted from the population of publicly-available information mainly the annual reports of publicly-listed companies on the Bursa Malaysia. 136 firm-year observations listed on Bursa Malaysia were identified to examine the relationship between the effectiveness of the board of directors and a modified audit opinion. Data used in this study are collected from two separate sources - annual reports and Datastream. Any missing financial figure from Datastream was acquired from the annual reports. To test the study's hypotheses, we use the pooled cross-sectional logistic regression analysis for 136 firm-year observations listed on Bursa Malaysia over the period 2009-2011. The evidence we have uncovered is consistent with the hypothesis that companies with large score of the board of directors' effectiveness are less possible to receive a modified audit opinion. Therefore, the result confirms that the combined effect of the board of directors' characteristics has a significant negative association with the likelihood of the companies receiving a modified audit opinion.

This research is the hair damage as treating a perm before and after that is compared the change of surface characteristics of human hair. On the basis of this, we would to show a basic data for hair damage prevention and hair improvement to keep the beautiful and healthy hair. Results are as follows; For the change of formational characteristics of hair surface, untreated hair before the perm treatment had smooth appearance overall and undamaged scale that is in pattern and finely folded was observed but damaged hair and extremely hair had uneven edge and damages throughout along with the dissolution of scale which the border of epidermal gap is unclear. Hair after a perm treatment caused cortical exposures due to extensive loss of scale during the treatment and even bubble effect. Protein perm, regular perm, soft perm, and direct heating perm, in that order, had the most damages to the hair.
