We conducted a systematic review to summarize providers' attitudes toward pay-for-performance (P4P), focusing on their general attitudes, the effects of P4P, their favorable design and implementation methods, and concerns. An electronic search was performed in PubMed and Scopus using selected keywords including P4P. Two reviewers screened target articles using titles and abstract review and then read the full version of the screened articles for the final selections. In addition, one reference of screened articles and one unpublished report were also included. Therefore, 14 articles were included in this study. Healthcare providers' attitudes on P4P were summarized in two ways. First, we gathered their general attitudes and opinions regarding the effects of P4P. Second, we rearranged their opinions regarding desirable P4P design and implementation methods, as well as their concerns. This study showed the possibility that some healthcare providers still have a low level of awareness about P4P and might prefer voluntary participation in P4P. In addition, they felt that adequate quality indicators and additional support for implementation of P4P would be needed. Most healthcare providers also had serious concerns that P4P would induce unintended consequences. In order to conduct successful implementation of P4P, purchaser should make more efforts such as increasing providers' level of awareness about P4P, providing technical and educational support, reducing their burden, developing a cooperative relationship with providers, developing more accurate quality measures, and minimizing the unintended consequences.

Foreign bodies in the airway are very import-tant and not uncommon conditions in the field of E.N.T., and practically there are many reports of them. Occasionally, it can be followed by some pulmonary complications and technical difficulty to remove. Therefore, foreign body in the trachea-bronchial tree is serious and, on occasion, fatal. Recently, the authors experienced 7 interesting cases of foreign bodies in the airway and a brief review of literature was made. Case 1. (1 year old male): A bit of walnut was coughed out spontaneously. Case 2. (2 years old male): A bit of raw chestnut was removed from the right main bronchus. Case 3. (21 Years old male): A pushpin was removed from the left main bronchus. Case 4. (1 year old male): A kind of bean was removed from the right main vronchus. Case 5. (4 years old male): A coiled steel spring (1.1cm$\times$2cm) was removed from the subglottic region. Case 6. (5 years old female): A shell of pine nut which had been impacted in the wall of right main bronchus was removed during right middle and lower lobectomy. Case 7. (2 years old male): A metal nail was removed from the rightposterior basal segmental bronchus during right lower lobectomy.

In hot strip rolling, a capability for precisely predicting roll force is crucial for sound process control. In the past, on-line prediction models have been developed mostly on the basis of Orowan's theory and its variation. However, the range of process conditions in which desired prediction accuracy could be achieved was rather limited, mainly due to many simplifying assumptions inherent to Orowan's theory. As far as the prediction accuracy is concerned, a rigorously formulated finite element(FE) process model is perhaps the best choice. However, a FE process model in general requires a large CPU time, rendering itself inadequate for on-line purpose. In this report, we present a FE-based on-line prediction model applicable to precision process control in a finishing mill(FM). Described was an integrated FE process model capable of revealing the detailed aspects of the thermo-mechanical behavior of the roll-strip system. Using the FE process model, a series of process simulation was conducted to investigate the effect of diverse process variables on some selected non-dimensional parameters characterizing the thermo-mechanical behavior of the strip. Then, it was shown that an on-line model for the prediction of roll force could be derived on the basis of these parameters. The prediction accuracy of the proposed model was examined through comparison with measurements from the hot strip mill.

Cardiac surgery in the neonate with congenital heart disease has progressed dramatically in the past three decades. However, low-birth-weight premie with congenital heart disease continue to challenge the intellectual and technical skills of those who care for them. We report a case of successful arterial switch operation in 1140g premie with TGA, IVS after 4 week care 1317gm.

Even though some authors have reported on the advantages of early total correction of complex heart disease, for low birth weight premature neonates, most surgeons prefer a multi-step approach to early total correction due to the many problems, such as the technical problems, the cardiopulmonary bypass management and etc. We report here on a successful case of early one-stage total repair of coarctation of the aorta and a ventricular septal defect in a 1,250 gram premature neonate.

We report an example of Pi2 pulsation exhibiting different frequency between dawn and dusk. This Pi2 pulsation occurred around 1932 UT on February 14, 2008, and was observed at low-latitude Bohyun (BOH, L = 1.35, MLT = 3.8) and Hermanus (HER, L = 1.83, MLT = 20.1) stations. The pulsation starts simultaneously at both stations but the frequency is higher at BOH than at HER. At the time of the Pi2, THEMIS-A (THA) and THEMIS-D (THD) were on dawn (L = 2.9, MLT = 5.3) and dusk (L = 2.8, MLT = 18), respectively, in the inner magnetosphere. We find a nearly identical waveform and period between THA ${\delta}Bz$ and BOH ${\delta}H$ and between THD ${\delta}Bz$ and HER ${\delta}H$ with a near $0^{\circ}$ phase delay. This observation implies that Pi2-associated fastmode wave in the inner magnetosphere is not excited globally as a single frequency at all longitudes. We suggest that the different frequency between dawn and dusk is due to dawn-dusk asymmetry of the plasmasphere.

In children, the snapping-knee syndrome is strongly suggestive of a diagnosis of discoid menisci. Furthermore the loss of extension of the knee suggests a diagnosis of torn lateral discoid meniscus. Symptomatic lateral discoid meniscus tear in a very young child, especially under the 3-year-old, was very rarely reported and the treatment protocol has not been established. Some therapeutic advancement was achieved in symptomatic lateral discoid meniscus but still technical difficulties exist. We undergone arthroscopic meniscal reshaping in a 26-month-old girl. At the time of postoperatively 2-year 9-month follow up, excellent result has achieved in clinical and functional outcome according to the scale of Ikeuchi without recurrence of symptom or postoperative complication. We reported out experience and results that arthroscopic reshaping procedure was done for management of symptomatic lateral discoid meniscus in a 26-month-old girl.

Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis manifest as demyelinating diseases of the peripheral and central nervous system. Concurrency of these two disorders is rarely documented in literature. A 4-year-old girl presenting with cough, fever, and an impaired walking ability was admitted to hospital. She had no previous complaints in her medical history. A physical examination revealed lack of muscle strength of the lower extremities and deep tendon reflexes. MRI could not be carried out due to technical problems; therefore, both Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis were considered for the diagnosis. Intravenous immunoglobulin treatment was started as first line therapy. Because this treatment did not relieve the patient's symptoms, spinal MRI was carried out on the fourth day of admission and demyelinating areas were identified. Based on the new findings, the patient was diagnosed with acute transverse myelitis, and high dose intravenous methylprednisolone therapy was started. Electromyography findings were consistent with acute polyneuropathy affecting both motor and sensory fibers. Therefore, the patient was diagnosed with concurrency of Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis. Interestingly, while concurrency of these 2 disorders is rare, this association has been demonstrated in various recent publications. Progress in diagnostic tests (magnetic resonance imaging and electrophysiological examination studies) has enabled clinicians to establish the right diagnosis. The possibility of concurrent Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis should be considered if recovery takes longer than anticipated.

Objective : The semi-jailing technique (SJT) provides stent-assisted remodeling of the aneurysm neck during coil embolization without grasping the coil delivery microcatheter. We retrospectively evaluated the efficacy and safety of SJT using a Neuroform3 stent for coiling of wide-necked intracranial aneurysms. Methods : We collected the clinical and radiological data between January 2009 and June 2015 of the wide-necked aneurysms treated with SJT using a Neuroform3 stent. Results : SJT using a Neuroform3 stent was attempted in 70 wide-necked aneurysms (68 patients). There were 56 unruptured and 14 ruptured aneurysms. The size of aneurysm ranged from 1.7 to 28.1 mm (mean 6.1 mm). The immediate angiographic results were complete occlusion in 55 aneurysms (78.6%), neck remnant in 7 (10.0%), and aneurysm remnant in 8 (11.4%). Overall, periprocedural complications occurred in 13 patients (19.1%), including asymptomatic thromboembolism in 7 (10.3%), symptomatic thromboembolism in 4 (5.9%), and symptomatic hemorrhagic complications in 2 (2.9%). Conventional angiography follow-up was obtained in 55 (78.6%) of 70 aneurysms (mean, 10.9 months). The result showed progressive occlusion in 7 aneurysms (12.7%) and recanalization in 1 aneurysm (1.8%). At the end of the observation period (mean, 17.5 months), all 54 patients without subarachnoid hemorrhage showed excellent clinical outcomes (modified Rankin Scale [mRS] 0), except two (mRS 1 or 2) and seven of 14 patients with subarachnoid hemorrhage remained symptom-free (mRS 0). Conclusion : In this report of 70 aneurysms, SJT using a Neuroform3 stent for coiling of wide-necked intracranial aneurysms showed good technical safety, as well as favorable clinical and angiographic outcomes.
