For recanalization of emergent large vessel occlusions (ELVOs), endovascular therapy (EVT) using newer devices, such as a stent retriever and large-bore catheter, has shown better patient outcomes compared with intravenous recombinant tissue plasminogen activator only. Intracranial atherosclerotic stenosis (ICAS) is a major cause of acute ischemic stroke, the incidence of which is rising worldwide. Thus, it is not rare to encounter underlying ICAS during EVT procedures, particularly in Asian countries. ELVO due to underlying ICAS is often related to EVT procedure failure or complications, which can lead to poor functional recovery. However, information regarding EVT for this type of stroke is lacking because large clinical trials have been largely based on Western populations. In this review, we discuss the unique pathologic basis of ELVO with underlying ICAS, which may complicate EVT procedures. Moreover, we review EVT data for patients with ELVO due to underlying ICAS and suggest an optimal endovascular recanalization strategy based on the existing literature. Finally, we present future perspectives on this subject.

" Row -Zone Tillage" systems apply tillage procedures only to narrow strips of land where the next crop rows will be planted. The tilled zones are no more than 25% of the field area. Row-zone tillage procedures of crop production are conservative, where in the soil remains partially covered with protective residues while crops are planted , fertilized , grown , and harvested in the row-zones. Specially adapted implements are being developed for these operations. There is potential for minimizing farm machinery inventories. Limited crop response data are available from Canada and the USA.d the USA.

Three essential components of self-regulating capital market includes trading clearing and regulation. These three procedures have to be excuted in accurate, prompt, and orderly way so that the markets can provide individual investors with confidence. In this study, we review these procedures and discuss how the quality service of them can be related to investor confidence. We will also discuss the details of regulatory process and especially how to monitor the stock price and volume for the detection of their unusual movements as the first procedure of regulation.

Audit review is the system to review the audit procedures performed and the audit opinion expressed by the independent auditors. The public audit review performed by Financial Supervisory Service (FSS) is regarded as one of the most important means to maintain the reliability of accounting information in Korea. We examinate the effect of audit review on earnings quality by using ERC (earnings response coefficient). We find that ERC of the sample group which issued the audit error reports after they were reviewed by SSB is more effective and higher than one of the non-reviewed group, matching group. We infer that the audit review system has the effectiveness in Korea.

The purpose of this paper was to review critiques on methodological problems relating to Piaget's researches in terms of its scientific nature. On the basis of review of literature, the following problems were pointed out: 1. Notwithstanding Piaget's emphasis on the scientific requirement for verification, Piaget was against the deductive method typical of scientific verification. 2. Piaget's theory was so vague that it couldn't be falsified. 3. Piaget ignored criticism of his method, and this was viewed as unscientific in the eyes of most scientists. 4. Avoiding the antecedent-consequence sequence of scientific experimentation, Piaget took the descriptive, rather than the explanative nature. 5. Piaget didn't accept individual differences in cognitive style in his research paradigm. 6. Piaget's experimental procedures looked very simple but they were too complex to understand what was happening. 7. Although Piaget's major ideas treated the child as the active constructor of reality, the child's experimental tasks were structured by experimenter. 8. Piaget's clinical method depended heavily upon language although the procedures required manipulation of objects. 9. Piaget always justified his experiments in terms of protocois selected from all the responses obtained. However, these protocols may not be the most representative responses or behaviors showing the child's cognitive structure.

Backgrounds : Taiwan has similar national health insurance (NHI) system for traditional medicine with South Korea. Recently, new quality improvement policies for traditional medicine is being attempted in Taiwan. Objectives : This study aimed to review the Taiwanese NHI system for Chinese Medicine (CM) and introduce quality improvement policies. Methods : Research articles, reports, government publications and year books which handled traditional medicine system and NHI system in Taiwan were searched and collected. The authors analyzed and summarized the contents in a qualitative manner. Results : In Taiwanese NHI system, CM procedures and medication for outpatients are reimbursed through a mix of fee-for-service and global budget payment system. CM shares 4% of total expenditure of NHI in Taiwan. Mostly, the expenses for procedures are reimbursed regardless of disease type, however, in the specialized program for quality improvement, CM doctors have to comply with standard operating procedures (SOPs). Conclusions : Taiwanese NHI system implemented SOP-based new reimbursement system for CM. Yet, the scientific evidences for SOPs are not sufficient, it can be useful references when we develope disease related reimbursement system for Korean Medicine in South Korea.

Objectives: This systematic review evaluated the influence of autoclave sterilization procedures on the cyclic fatigue resistance of heat-treated nickel-titanium (NiTi) instruments. Materials and Methods: A systematic search without restrictions was conducted in the following electronic databases: PubMed, Scopus, Web of Science, ScienceDirect, Cochrane, and Open Grey. The hand search was also performed in the main endodontic journals. The eligible studies were submitted to the methodological assessment and data extraction. Results: From 203 abstracts, a total of 10 articles matched the eligible criteria. After reading the full articles, 2 were excluded because of the absence of the heat-treated instruments in the experimental design and 3 due to the lack of a control group using heat-treated instruments without autoclave sterilization. From the 5 included studies, 1 presented a low risk of bias, 3 presented moderate and 1 high risk. It was observed heterogeneous findings in the included studies, with autoclave sterilization cycles increasing, decreasing or not affecting the cyclic fatigue life of heat-treated NiTi instruments. However, the retrieved studies evaluating the cyclic fatigue resistance of endodontic instruments presented different protocols and assessing outcomes, this variability makes the findings less comparable within and also between groups and preclude the establishment of an unbiased scientific evidence base. Conclusions: Considering the little scientific evidence and considerable risk of bias, it is still possible to conclude that autoclave sterilization procedures appear to influence the cyclic fatigue resistance of heat-treated NiTi instruments.

Botulinum toxin type A (BoNT-A), onabotulinumtoxinA (Botox) was approved by the United States Food and Drug Administration for temporary improvement of glabellar lines in patients 65 years and younger in 2002, and has also been used widely for aesthetic purposes such as hyperhidrosis, body shape contouring, and other noninvasive facial procedures. BoNT-A inhibits presynaptic exocytosis of acetylcholine (ACh)-containing vesicles into the neuromuscular junction at cholinergic nerve endings of the peripheral nervous system, thereby paralyzing skeletal muscles. ACh is the most broadly used neurotransmitter in the somatic nervous system, preganglionic and postganglionic fibers of parasympathetic nerves, and preganglionic fibers or postganglionic sudomotor nerves of sympathetic nerves. The scientific basis for using BoNT-A in various cosmetic procedures is that its function goes beyond the dual role of muscle paralysis and neuromodulation by inhibiting the secretion of ACh. Although the major target organs for aesthetic procedures are facial expression muscles, skeletal body muscles, salivary glands, and sweat glands, which are innervated by the somatic or autonomic nerves of the peripheral cholinergic nerve system, few studies have attempted to directly explain the anatomy of the areas targeted for injection by addressing the neural physiology and rationale for specific aesthetic applications of BoNT-A therapy. In this article, we classify the various cosmetic uses of BoNT-A according to the relevant component of the peripheral nervous system, and describe scientific theories regarding the anatomy and physiology of the cholinergic nervous system. We also review critical physiological factors and conditions influencing the efficacy of BoNT-A for the rational aesthetic use of BoNT-A. We hope that this comprehensive review helps promote management policies to support long-term, safe, successful practice. Furthermore, based on this, we look forward to developing and expanding new advanced indications for the aesthetic use of BoNT-A in the future.
