Implant-supported overdenture is a reliable treatment option for the patients with edentulous mandible when they have difficulty in using complete dentures. Several options have been used for implant-supported overdenture attachments. Among these, bar attachment system has greater retention and better maintainability than others. SFI-Bar$^{(R)}$ is prefabricated and can be adjustable at chairside. Therefore, laboratory procedures such as soldering and welding are unnecessary, which leads to fewer errors and lower costs. A 67-year-old female patient presented, complaining of mobility of lower anterior teeth with old denture. She had been wearing complete denture in the maxilla and removable partial denture in the mandible with severe bone loss. After extracting the teeth, two implants were placed in front of mental foramen, and SFI-Bar$^{(R)}$ was connected. A tube bar was seated to two adapters through large ball joints and fixation screws, connecting each implant. The length of the tube bar was adjusted according to inter-implant distance. Then, a female part was attached to the bar beneath the new denture. This clinical report describes two-implant-supported overdenture using the SFI-Bar$^{(R)}$ system in a mandibular edentulous patient.

The organization shall minimize business risks associated with customer information leaks. Enhance information security activities through voluntary pre-check and must find a way to detect the personal information leakage caused by carelessness and neglect accident. Recently, many companies have introduced an information leakage prevention solution. However, there is a possibility of internal data leakage by the internal user who has permission to access the data. By this thread it is necessary to have the environment to analyze the habit and activity of the internal user. In this study, we use the SFI analytical technique that applies RFM model to evaluate the insider activity levels were carried out case studies is applied to the actual business.

Edentulous patients with severe alveolar bone resorption have trouble with using traditional complete denture. In order to overcome these problems, implant-retained overdenture was developed. SFI-bar$^{(R)}$ system can save time and cost compared to other existing bar systems which need complicated laboratory procedures because it can be adjusted directly in a patient's mouth. A 55-year-old male, who had experienced a fractured lower old implant-retained overdenture, wanted a durable and painless denture. The fractured Locator$^{(R)}$ attachments were removed and edentulous mandible was restored with SFI-bar$^{(R)}$. A 77-year-old female with a medical history of the Parkinson's disease and severely absorbed alveolar bone of mandible, wanted to wear a retentive mandibular denture without pain. After placing two implants in front of mental foramen, two adaptors were connected to two implants and a tube bar was connected to the adaptors. A female part fitted to the bar was attached to the new denture. These clinical reports describe two-implant-retained overdenture using the SFI-bar$^{(R)}$ system in mandibular edentulous patients. Since the patients were satisfied esthetically and functionally during 2 years' observation, we would like to report cases.

말초신경은 외상이나 질병 등 여러 가지 원인으로 손상되기 쉬우며, 손상의 정도가 심하거나 치료가 지연되는 경우에는 심각한 기능 소실을 초래할 수 있다. 본 연구에서는 수영이 말초신경손상후 운동기능의 회복과 뇌유인성 신경영양인자 (brain-derived neurotrophic factor, BDNF) mRNA의 발현에 미치는 효과를 알아보기 위하여, 흰쥐 좌골신경에 압박 손상을 가하고 수영을 적용한 후 보행궤적분석 (walking track analysis)과 역전사연쇄반응 (reverse transcription-polymerase chain reaction, RT-PCR)을 실시하였다. 그 결과, 좌골신경 압박손상된 쥐는 특징적인 보행패턴을 나타내어 좌골신경기능지수 (sciatic function index, SFI)가 현저히 낮아졌으며, BDNF mRNA의 발현이 증가하였다. 좌골신경 압박 손상후 수영을 한 쥐에서는 SFI가 현저히 향상되었으며, BDNF mRNA의 발현은 억제되었다. 이러한 결과는 말초신경손상후 수영이 BDNF mRNA의 발현을 조절함으로써 기능 회복을 촉진시키는 효과적인 치료방법이 될 수 있음을 제안하고 있다.

오늘날 네트워크 서비스에 대한 수요가 증가함에 따라 네트워크 트래픽 또한 증가하고 있다. 이는 네트워크 서비스 구성을 복잡하게 만들어 최종 사용자에게 전달되는 네트워크 기능의 동적 구성이 요구된다. Service Function Chaining (SFC)은 일련의 Service Function (SF) 세트로 구성된 새로운 네트워크 서비스 배포 모델이다. SFC는 특정 서비스에 따라 플로우를 분류하여 네트워크 운영자의 효율적인 서비스 제공을 보장한다. SFC의 성능은 SFC를 구성하는 SF Instance (SFI)와 상관 관계를 가진다. 이때 다수의 SFC 환경에서 단일의 SFI 사용 시, 트래픽 오버플로우가 발생할 수 있다. 따라서, 본 논문에서는 확장 가능한 SFC 프로비저닝을 위한 Monitoring as a Service (MaaS)를 제안한다.

Lard was randomly interesterified to improve handling efficiency with increase of plasticity, and it's physicochemical properties and adaptability for making pie were investigated. Fatty acid and triacylglycerol composition were not changed after interesterification. Interesterified lard could be useful during winter because the handling was convenient due to drop in the temperature range of $18{\sim}23.5^{\circ}C$ in lard and $13{\sim}19.5^{\circ}C$ in interesterified lard with SFI $15{\sim}25$. Interesterified lard was decreased in the extensibility by change of crystal form, and not suitable for making pie as the inferior characters for layers forming, appearance and shortness. But interesterified lard mixed with plastic fat of high extensibility showed the possibility of making pie, and the maximum mixture ratio was 50% for good pie quality.

Objectives : Peripheral nerve injuries are commonly encountered clinical problem and often result in severe functional deficits. The aim of this study is to evaluate the effects of aqueous extract of Achyranthes japonica(AJ) on functional recovery in sciatic nerve after crushed sciatic nerve injury. Methods : In the present study, the animals in the AJ-treated groups received the aqueous extract of AJ at the respective doses orally for 13 consecutive days. In order to assess the effects of the aqueous extract of AJ on function recovery in crushed sciatic nerve injury, sciatic functional index(SFI) was performed. c-Fos expression in the paraventricular nucleus(PVN) and ventrolateral periaqueductal gray(vIPAG), and neurofilament, and the expressions of brain-derived neurotrophic factor(BDNF), nerve growth factor(NGF) following crushed sciatic nerve injury in rats were investigated. For this, immunohistochemistry and western blot were performed. Results : In the present study, crushed sciatic nerve injury showed characteristic gait changes showing decrease of SFI value and treatment with the aqueous extract of AJ significantly enhanced the SFI value. Neurofilament expression in the sciatic nerve was decreased by crushed sciatic nerve injury and treatment with the AJ increased neurofilament expression. The expressions of BDNF and NGF in the sciatic nerve were increased following crushed sciatic nerve injury and treatment with the AJ significantly controlled the sciatic nerve injury-induced increment of BDNF and NGF expressions. c-Fos expressions in the PVN and vIPAG were increased following crushed sciatic nerve injury and treatment with the AJ significantly suppressed the sciatic nerve injury-induced increment of c-Fos expressions. Conclusions : These results suggest that AJ treatment after crushed sciatic nerve injury is effective in the functional recovery by enhancing axonal regeneration and suppressing of pain.

Objectives : This study was designed to evaluate the effects of Ohyaksungi-san(Wuyaoshungi-san) and Jungsongouhyul pharmacopuncture on pain reduction and nerve regeneration after crush injury in rat sciatic nerve. Methods : Animal model was produced through crush injury of right sciatic nerve and they were divided into four groups; Group I: no treatment control group; Group II: experimental group treated with Ohyaksungi-san(Wuyaoshungi-san); Group III: experimental group treated with Jungsongouhyul pharmacopuncture; Group IV: experimental group treated with Ohyaksungi-san(Wuyaoshungi-san) and Jungsongouhyul pharmacopuncture. For the assessment of pain, this study was observed the paw withdrawal latency(PWL) and immunoreactivity on the substance-P. For the assessment of nerve regeneration, the sciatic functional index(SFI) and immunoreactivity on the BDNF were measured. Results : 1. In the assessment of pain, the PWL of experimental groups was significantly higher than control group and group IV was significantly higher than other groups at the all days. 2. In immunohistochemical response of substance-P, as time passes, the immunoreactivity of all groups were decreased gradully. Especially, group IV had the lowest immunoreactivity. 3. In the assessment of SFI, the SFI of experimental groups were significantly higher than control group. 4. In immunohistochemical response of BDNF, the BDNF immunoreactivity of all groups was significantly higher than control group and especially, group IV had the highest immunoreactivity at the 14 days after injury. 5. H & E stain was used on the liver and kidney to investigate toxic effect of Jungsongouhyul pharmacopuncture and Ohyaksungi-san(Wuyaoshungi-san) on on 21 days after injury. However there were no any toxic effects both control group and experimental groups. Conclusions : On the basis of these results, we propose that Ohyaksungi-san(Wuyaoshungi-san) and Jungsongouhyul pharmacopuncture were related to pain reduction and motor nerve recovery, also decreased substance-P expression and increased BDNF expression after crush injury of sciatic nerve, especially these two treatments could be more effective when they were combined simultaneously.
