Objectives : To establish an effective collaborate medicine treatment of acupuncture and western medicine for treating frozen shoulder patients. Methods : 59 voluntary patients were randomly assigned to Eastern treatment group(E group, n=22), Western treatment group(W group, n=17) and East-West treatment group(EW group, n=20). The E group received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. The EW group received acupuncture and injection treatment including nerve block. All groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after treatment based on the change in shoulder Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). The obtained data were analyzed and compared. Results : The patient's satisfaction scores were E group 5.67, W group 7.73 and EW group 7.67. The E group and the EW group showed significant improvement in abbduction, adduction and flexion(p<0.05). The W group showed significant improvement in adduction(p<0.05). Abduction significantly improved(p<0.05) in the EW group compared to E group and W group. Flexion also showed improvement in the EW group, but the difference among the 3 groups was statistically insignificant. The three group's difference of change in extension and adduction was insignificant(p>0.05). Conclusion : Acupuncture and nerve block alone significantly improved ROM in frozen shoulder patients. Also collaborate treatment of acupuncture and nerve block significantly improved ROM in frozen shoulder patients. But the difference of the three treatments were significant only for improving abduction(p<0.05).

복합 레진으로 수복된 세 가지 첨와형태 와동의 파절 저항성에 관한 연구

최훈수,신동훈 大韓齒科保存學會 2008 Restorative Dentistry & Endodontics Vol.33 No.3

심미성 복합레진은 자연 치질을 보존시키며 나아가 잔존 치질의 강도를 강화시켜 준다. 복합레진 수복시 더 많은 치질을 남기기 위해 첨와 (undercut) 형태의 교합면 치질을 남긴 채 복합레진으로 수복하는 경무가 많으나,어느 정도 강도가 복원되는지에 대해서는 잘 알려져 있지 않다. 이에 본 연구에서는 첨와 형태의 와동을 잔존 치질의 두께 (법랑질 /법랑질과 상아질)에 따라 형성하고 복합레진으로 충전한 경우, 수복된 치아의 파절 저항성을 손상이 없는 자연치와 비교평가하였다. 상악 대구치 40개의 교합면을 편평하게 삭제한 후 방사선 사진에서 치수각의 위치를 확인하였다. 대상 치아를 각 10개씩 4개군으로 분류하였으며, 1 ~ 3군은 실험군으로 모두 협측에 깊이 7 ㎜, 근원심 폭경 5 ㎜의 첨와 형태 와동을 형성하였고, 와동저에서 치수각까지의 거리를 약 0.5 ㎜로 유지하였으며 교합면쪽의 치질 두께를 달리하였다. 1군은 법랑질과 소량의 상아질로 구성된 치질 두께를 1 ㎜, 2군은 법 랑질과 상아질의 두께를 1.5 ㎜, 3군은 법 랑질과 상아질의 두께를 2 ㎜가 되도록 하였고, 4군은 건전한 자연치를 와동형성 없이 대조군으로 사용하였다. 두께 측정은 방사선 사진을 스캔한 후 길이 확대 프로그램을 이용하였다. 각 와동을 37% 인산으로 산부식한 다음 단일병 접착제 Single Bond™ (3M/ESPE, USA)를 적용하였고 흔합형 복합레진 Filtek Z-250™ (3M/ESPE, USA)을 사용하여 적층 충전하였다. 치아를 실온에서 증류수에 24시간 동안 보관한 다음 Sof-Lex system (3M/ESPE, USA)을 사용하뗘 연마하였다. 이후 자가중합형 레진에 교합면을 기저부에 평행한 상태로 치근부를 매몰한 다음 Universal testing machine (Zwick Z010, Germany)에서 지름 3 ㎜의 staineless steel rod를 1 mm/min의 cross-head speed로 하중을 가하여 파절 강도를 측정하였다. 통계 분석은 95%유의 수준의 One-way ANOVA와 Tukey test를 이용하였으며 다음과 같은 결과를 얻었다. 1. 와동 형성 후 복합레진을 수복한 군들은 대조군에 비해 약 75%의 파절 강도를 보였다. 2. 교합면쪽 잔존 치질의 두께에 따른 파절 저항은 유의한 차이를 보이지 않았다 (p>0.05). 복합레진을 이용하여 첨와 형태의 와동을 수복한 후 파절 강도를 측정 한 결과 건전 치아보다는 강도가 낮았지만, 상부의 잔존 치질이 대부분 법랑질로 이루어진 경우에도 복합 레진으로 수복하면 건전 치아 파절 강도의 75%까지 유지할 수 있다는 결론을 얻었다. It was reported that esthetic composite resin restoration reinforces the strength of remaining tooth structure with preserving the natural tooth structure. However, it is unknown how much the strength would be recovered. The purpose of this study was to compare the fracture resistance of three types of undermined cavity filled with composite resin with that of non-cavitated natural tooth. Forty sound upper molars were allocated randomly into four groups of 10 teeth. After flattening occlusal enamel, undermined cavities were prepared in thirty teeth to make three types of specimens with various thickness of occlusal structure (Group 1 ~ 3). All the cavity have the 5 ㎜ width mesio-distally and 7 ㎜ depth bucco-lingually. Another natural 10 teeth (Group 4) were used as a control group. Teeth in group 1 have remaining occlusal structure about 1 ㎜ thickness, which was composed of mainly enamel and small amount of dentin. In Group 2, remained thickness was about 1.5 ㎜, including 0.5 ㎜ thickness dentin. In Group 3, thickness was about 2.0 ㎜, including 1 ㎜ thickness dentin. Every effort was made to keep the remaining dentin thickness about 0.5 ㎜ from the pulp space in cavitated groups. All the thickness was evaluated with radiographic Length Analyzer program. After acid etching with 37% phosphoric acid, one-bottle adhesive (Single Bond™, 3M/ESPE, USA) was applied following the manufacturer' s recommendation and cavities were incrementally filled with hybrid composite resin (Filtek Z-250™, 3M/ESPE, USA). Teeth were stored in distilled water for one day at room temperature, after then, they were finished and polished with Sof-Lex system. All specimens were embedded in acrylic resin and static load was applied to the specimens with a 3 ㎜ diameter stainless steel rod in an Universal testing machine and cross-head speed was 1 mm/min. Maximum load in case of fracture was recorded for each specimen. The data were statistically analyzed using one-way analysis of variance (ANOVA) and a Tukey test at the 95% confidence level.

As a mobility support for IP have studied, Internet Engineering Task Force(ITEF) standardized the mobile IPv6 protocol. When a mobile node moves between networks, MIPv6 maintains connectivity to network and supports seamless communication, and these processes are called a Handover. IEEE 802.21 standardized MIH(Media Independent Handover) for seamless Handover. MIH used three services for Handover between low layer and upper layer . In this paper, we designed two modes on existing MIH for seamless Handover. We implemented a dual-interface mobile host(MH) model in network simulation2 (ns2) to evaluate how it performs in comparison with single-interface MH.

Purpose : To longitudinally observe the healing process of extracted socket and the alterations of the residual ridge in healthy adult dogs using cone beam CT (CBCT). Materials and Methods : The mandibular premolars of two beagle dogs were removed and the extraction sites were covered with the gingival tissue. CBCTs (3D X-ray CT scanner, Alphard vega, Asahi Co.) were taken at baseline and at 1 week interval for 12 weeks. Radiographic density of extracted wounds was measured on normalized images with a custom-made image analysis program. The amount of alveolar crestal resorption after the teeth extraction was measured with a reformatted three-dimensional image using CBCT. Bony healing pattern of extracted wound of each group was also longitudinally observed and analyzed. Results : Dimensional changes occurred during the first 6 weeks following the extraction of dogs’ mandibular premolars. The reduction of the height of residual ridge was more pronounced at the buccal than at the lingual aspect of the extraction socket. Radiographic density of extracted wounds increased by week 4, but the change in density stabilized after week 6. New bone formation was observed at the floor and the peripheral side of extracted socket from week 1. The entrance of extracted socket was sealed by a hard-tissue bridge at week 5. Conclusion : The healing process of extracted wound involved a series of events including new bone formation and residual ridge resorption.

It is noteworthy that most unidentified dead are unnatural and violent deaths. The accurate identification of a decedent permits certification of death and notification of next of kin. Only then may they proceed with the probate of wills, apply for disbursement of benefits and insurance, and begin to work through the grieving process. Law enforcement agencies need positive identification to pick up the leads of investigation to develop suspects, establish the corpus delicti of homicide and reconstruct the sequence of events of a crime. Agencies and a variety of consultants are involved in recognizing and developing the unique features of a decedent that lead to identification. Cooperative working relations with newspaper and other media will help in publicizing the need for persons with information to come forward diagrammatically. In this paper, 5 individual identification cases in unexpected or homicidal deaths are described. The comparison between the postmortem and antemortem records show that the victims are correctly identified.

This study was conducted to evaluate the effects of microbial inoculation on sewage sludge composting. The number and species of microorganisms in sewage sludge sampled on February were higher than those sampled on August. The composting of sewage sludge is inhibited by the polyacrylamide cation, which was used as a coagulant and known to repress the growth of microorganisms. The growth of all microorganisms was inhibited by the addition of the polyacrylamide cation at a concentration of more than 0.8%. The species and viable counts of microorganisms were observed to increase during composting sewage sludge by inoculation of the effective microorganisms and addition of the pine tree sawdust as a bulking agent, compared with those without inoculation. A variety of organisms in compost(sewage sludge plus sawdust) were observed after composting for 30 days, such as Fragilaria sp., Proales sp., Vorticella sp., Schizothrix sp., Anabaena sp., Zoothaminium sp., Epstylis sp., Arcella sp., Balantidium sp., Actinophrys sp., Synedra sp., Euglypha sp., Ulothrix sp., Anacystis sp., and Clostium sp.

This study was performed to investigate the surface properties of electrochemically oxidized pure titanium by anodic spark deposition technique. Titanium plates of 10×10×1 ㎜ were polished sequentially from # 300 to # 1,000 emery paper. They were ultrasonically washed in ethyl alcohol and acetone for 5 min and dried in a desiccator. Titanium plates and titanium screw implants were anodized in an electrolytic solution that was dissolved calcium and phosphate in water. The electrolytic voltage was set in the range of 190-340 V and the current density was 30 ㎃/㎠. The surface oxide film was characterized by X-ray deffractometer(XRD), scanning electron microscope(SEM) and X-ray photoemission spectroscopy(XPS). The main crystal structure of the titanium oxide was anatase type as analyzed with thin-film X-ray diffractometery. The diameter of micropores increased with increasing the spark forming voltage. The porous coatings showed the growth of cell structure and more compact texture with increasing the spark forming voltage. Microcracks were examined in the coating formed at voltage of 340 V. Ca/P ratio in coatings was increased with increasing the voltage.
