The main purpose of this study is to analyse what are the key financial innovations in the euro area electronic payment systems. TARGET2 is the RTGS-system provided through the Eurosystem. It is used for settling central bank operations, for large interbank transfers in euro and also for other euro-denominated transfers. The specific features of TARGET2 include processing in real time, settlement in central bank money and immediate finality. In addition, the SEPA is a payment-integration initiative of the European Union for simplification of bank transfers denominated in euro. In particular, the main innovations consist of the completion of the phased migration to the TARGET2 infrastructure, and the introduction of a single retail payment market in euro - the SEPA and its products, schemes and frameworks. As the study analyse, the key innovations consist of the TARGET2 introduction, SEPA establishment and migration towards the T2S system. These innovations will lead to a better understanding of the payment and settlement systems' behavior in stress situations and to enhance the stability of the euro area financial system. Moreover, the successful integration of the European payment and settlement infrastructures will further contribute to the integration of the European financial markets, as well as to their higher competitiveness.

Distributed arrival time control (DATC) is a distributed feedback control algorithm for real-time scheduling problems in dynamic operational environment. Even though DATC has provided excellent performance for dynamic scheduling problems, it can be improved by considering the following considerations. First, the original DATC heavily depends on the quality of initial solution. In this paper, well-known dispatching rules are incorporated DATC algorithm to enhance its performance. Second, DATC improves its solution with adjusting virtual arrival times of jobs to be scheduled in proportion to the gap between completion time and due date iteratively. Since this approach assigns the same weight to all gaps generated with iterations, it fails to utilize significantly more the latest information (gap) than the previous ones. To overcome this issue we consider exponential smoothing which enable to assign different weight to different gaps. Using these two consideration This paper proposes A-DATC (Advanced-DATC). We demonstrate the effectiveness of the proposed scheduling algorithm through computational results.

Recently, in accordance with increase of the desire for Sports for All(Life Sports), the swimming pools in many areas are under construction. However, since they used many of the reflexible finish-materials on account of the characteristics of hydrophilic space, most of the Indoor Swimming Pools are generating the excessive reverberation. Such reverberation is bringing about the problem that obstructs the oral communication between the coach and the player, and the Clearness of Sound, besides the sport activity. On this viewpoint, on the object of the actually built indoor swimming pool, after the conduct of an optimized acoustics design by the remodeling through a computer simulation, and by carrying out the Psycho-Acoustics Experiment utilizing of Auralization Technique which is able to experience Virtual Sound Field at the stage of designing, then this thesis has attempted to appraise on the acoustic condition after the completion of construction. It is considered that such result of the study could be utilized as the useful data that enables to improve the curtailment effect of construction cost as well as the acoustic capability, by means of the presupposition control on the acoustic problem from the stage of design, for the occasion when the similar indoor swimming pool is planning to build, henceforth.

Chordoma is a malignant tumor arising from the primitive notochord involving the axial skeleton. It usually occurs at sacrococcygeal and besisphenoidal area but only rarely does at other vertebral areas, especially at the thoracic vertebrae. It has a slow growth rate and is locally aggressive with an extremely high rate of local recurrence. Either surgery or radiation alone often fails to cure the disease and the local failure is the main cause of treatment failure and death. Overall 5 year survival rate is less than $10\%$. Useful palliation or occasional cure can be obtained by the combination of surgery and radiotherapy. After incomplete resection, the tumor requires radiation dose of 7,000 cGy or more over 6-7 weeks for local control. Tumor regression is slow in response to irradiation and continuation of the regression for several months after completion of RT is not unusual. We report a case of chordoma of the thoracic vertebra, the site of extreme rarity, which showed good local control after partial resection and radiation therapy. He is well and alive without any evidence of recurrence after 13 months of treatment with near complete tumor regression.

The development of ozone SRP (Standard Reference Photometer) designated as a G-7 project by the Korean Ministry of Environment began 1997 and is now nearly completed. With the completion of the ozone SRP we will not only acquire a qualification to participate in the international ozone calibration system but also enhance calibration credibility of ozone similarly to that of other ambient air pollution monitors. As the ozone SRP uses highly cleaned blank air that can be distinguished from general ozone analyzer, it is possible to reduce errors associated with the determination of ozone via elongation of the absorption length as long as 1 meter In addition, gas chopping method hat been adopted to cut down interference of other substances and time drift. Furthermore, the system has also been modified to minimize the strayed ultra-violet noise along the light path. In this paper, a new method for uncertainty evaluation has been introduced, which is guided by the ISO (International Standard Organization) GUM (Guide to the Expression of Uncertainty in Measurement) through assessments of the uncertainty type B (that was impossible to estimate before) as well as the uncertainty type A (based on statistics).

Objective: Oocyte-specific homeobox 4 (Obox4) is preferentially expressed in oocytes and plays an important role in the completion of meiosis of oocytes. However, the Obox4 expression pattern has not been reported yet. In this study, we investigated the subcellular localization of Obox4 using a green fluorescent protein (GFP) fusion expression system. Methods: Three regions of Obox4 were divided and fused to the GFP expression vector. The partly deleted homeodomain (HD) regions of Obox4 were also fused to the GFP expression vector. The recombinant vectors were transfected into HEK-293T cells plated onto coated glass coverslips. The transfected cells were stained with 4',6-diamidino-2-phenylindol and photographed using a fluorescence microscope. Results: Mutants containing the HD region as well as full-length Obox4 were clearly localized to the nucleus. In contrast, the other mutants of either the N-terminal or C-terminal region without HD had impaired nuclear localization. We also found that the N-terminal and C-terminal of the Obox HD contributed to nuclear localization and the entire HD was necessary for nuclear localization of Obox4. Conclusion: Based on the results of the present study, we demonstrated that the intact HD region of Obox4 is responsible for the nuclear localization of Obox4 protein in cells.

Ovarian cancer patients need a surveillance program for the detection of tumor progression after completion of treatment. The methods generally consist of history taking, physical examination, tumor marker monitoring and imaging. However, the details of recurrence detection with each method are not well defined. To clarify this issue, ovarian cancer patients who achieved complete or partial responses and developed tumor progression at the follow up time between January 2004 and December 2010 in University Hospital Chiang Mai, Thailand, were reviewed. Clinical data, CA 125 level and imaging results at the tumor progression time were recorded and analyzed. There were 144 ovarian cancer patients meeting the inclusion criteria with the mean age of 51 years and 62.5% of them were in an advanced stage. Complete response was achieved in 89 patients (61.8%) after primary treatment. The median progression free survival and overall survival were 15.5 months and 37.5 months, respectively. Abnormal symptoms presented in 49.3% of the studied patients and 59.7% developed physical examination abnormalities. In addition, CA 125 was elevated in 89.6% while in 74.3% of tumor progression was identified by CT-scan. Short treatment time period and a high level of CA 125 were significant independent prognostic factors in these patients. In conclusion, careful history taking, physical examination and monitoring of CA 125 levels are important methods for tumor progression detection in a surveillance program for epithelial ovarian cancer patients.

Purpose of the research: In response to the increasing number of selling centers, this paper examines factors that influence the voluntary participation in selling centers. The goal of this study is to enable organizations to meet changing market conditions, which require interdisciplinary collaboration during sales projects. This paper also discusses potential problems which may occure during the implementation of these factors in practice. Research design and methodology: The research method consists of a qualitative cross-sectional study with N=12 interviewees. All interviewees are current or former selling center participants. During the interview sessions, semi-structured face-to-face interviews were used, which were evaluated using a qualitative content analysis. In addition, a frequency analysis was applied to evaluate the number of mentions per factor. Research results: In total, five factors were raised in order to improve the framework conditions of voluntary participation. These factors are performance incentives, transparency, availability of resources, goal orientation, as well as collegiality and affiliation. Major conclusions: The identified factors are also under discussion in the existing literature. Knowing about factors that generate voluntary participation in selling centers pays off particularly in improving the probability of completion of sales projects in which buying centers and selling centers are working together.

In this study, the effects of the various conditions of frosting and defrosting on the behavior of defrosting in a fin-tube heat exchanger have been examined experimentally. The electric heater is used for defrosting in a fin-tube heat exchanger It is shown that there are several local maxima in the water draining rate. The amount of residual water on the heat exchanger after the completion of defrosting is kept constant due to surface tension on the heat exchanger. Without considering the degradation of the thermal performance due to the frosting, the defrosting efficiency is improved with increasing amount of the frost irrespective of the frosting condition. The defrosting behavior is affected by the frosting density as well as the frost accumulation, which vary with the experimental operating conditions during the frosting period. The heat loss to the surrounding air decreases, and the melting and defrosting efficiencies show high values with decreasing heat input.

This paper suggests a two-phase look-ahead Banker's algorithm for efficient operation of capacitated automated production systems. The algorithm improves the ability of detecting safe states of the previous one by considering the possibility of processing each job to completion at once as well as partial movement between jobs. The improved performance of the proposed algorithm is testified by performing numerical experiment in terms of (i) detection rate of safe states and (ii) system throughput and verified by using paired t-test.
