우리나라도 이제는 범죄피해자의 보호 지원을 위한 질 높은 서비스를 제공할 만큼 경제적 성장을 이루었다고 본다. 지금까지는 법무부에서 범죄피해자 보호 지원업무를 전담해오다가 최근 경찰청에서도 범죄피해자 보호 지원을 경찰의 주요 업무로 인식하고 각종 서비스를 제공하고 있다. 사실 형사단계로 본다면, 검찰과 법무부보다는 사건직후 피해자를 처음 접하는 경찰에서 즉각적인 범죄피해자 보호 지원을 하는 것이 바람직하기는 하다. 문제는 법령과 제도 상 경찰은 서비스제공에 한계가 있지만, 경찰의 피해자 보호 지원의 중요성을 감안할 때, 민관협동 형태의 범죄피해자 보호 지원 모델을 탐색해볼 필요가 있다. 물론, 우선 법무부의 민관협동 체제와의 새롭게 관계정립이 필요하고, 경찰의 특성을 살려서 피해자에게 제공할 수 있는 서비스의 내용을 정비하고 민관협동 형태로 간다면, 어디까지 경찰에서 서비스를 제공할 것인지 방향도 정해질 것이다. 선진국의 경우 경찰과 민간기구의 상호 협조가 매우 긴밀하게 이루어지고 있으며, 이는 범죄피해자에게 실질적인 보호와 지원의 성과로 나타나고 있다. 이에 본 연구는 경찰단계에서 범죄피해자 보호 지원의 문제점을 검토해보고, 그 개선방안에 대하여 다음과 같이 제시하였다. 첫째는 범죄피해자 보호지원에 있어서 가장 먼저 접하는 경찰의 역할을 재정립하는 것이고, 둘째는 경찰서별로 피해자전담경찰관과 피해자 보호사 등의 상시 협력체계를 구축하는 것이며, 셋째는 경찰단계에서 피해자보호지원이 가능한 서비스의 종류를 개발하는 것이고, 넷째는 범죄피해자의 임시숙소 또는 신변보호를 위한 안전지대의 기능을 담당할 피해자종합지원센터를 전국적으로 개소하는 방안, 다섯째는 지역권내에 범죄피해자의 보호지원을 위한 유관기관 담당자로 구성된 솔루션회의의 정례화, 여섯째는 범죄피해자의 보호는 경찰 등의 국가기관에서, 범죄피해자에 대한 지원은 지방자치 단체의 복지부서에서 담당하고 종합적으로 사후관리하는 방안을 제시하였다.

Some odontogenic infections erode into fascial spaces directly and spread toward lymphatic tissues and blood streams. The principal maxillary primary spaces are the canine, buccal, and infratemporal space, the next secondary spaces are the masseteric, temporal and pharygeal space. As a result of the infection, trismus and orocutaneous fistula may be occurred. Trismus is owing to conditions not associated with temporomandibular joint itself and may be of myogenic, neurogenic, or psychogenic nature. Muscular trismus is due to infection adjacent to the elevator muscles of the jaw. The four principles of treatment of infection are as follows: (1) removal of the cause, (2) establishment of drainage, (3) institution of antibiotic therapy, and (4) provision of supportive care, including rest, nutrition and physiotherapy. Jaw physiotherapy is necessary to increase the amount of mouth opening and regain normal muscle tone. If proper care of odontogenic infection could be attained, the orocutaneous fistula will heal and close spontaneously by wound contraction mechanism of natural homeostatic response. This is a case report of the care of trismus and orocutaneous fistula due to fascial space abscess by advanced odontogenic infection in a physically disabled patient.

Objective : Craniovertebral junctional anomalies constitute a technical challenge. Surgical opening of atlantoaxial joint region is a complex procedure especially in patients with nuchal deformity like basilar invagination. This region has actually very complicated anatomical and functional characteristics, including multiple joints providing extension, flexion, and wide rotation. In fact, it is also a bottleneck region where bones, neural structures, and blood vessels are located. Stabilization surgery regarding this region should consider the fact that the area exposes excessive and life-long stress due to complex movements and human posture. Therefore, all options should be considered for surgical stabilization, and they could be interchanged during the surgery, if required. Methods : A 53-year-old male patient applied to outpatients' clinic with complaints of head and neck pain persisting for a long time. Physical examination was normal except increased deep tendon reflexes. The patient was on long-term corticosteroid due to an allergic disease. Magnetic resonance imaging and computed tomography findings indicated basilar invagination and atlantoaxial dislocation.The patient underwent C0-C3-C4 (lateral mass) and additional C0-C2 (translaminar) stabilization surgery. Results : In routine practice, the sites where rods are bound to occipital plates were placed as paramedian. Instead, we inserted lateral mass screw to the sites where occipital screws were inserted on the occipital plate, thereby creating a site where extra rod could be bound.When C2 translaminar screw is inserted, screw caps remain on the median plane, which makes them difficult to bind to contralateral system. These bind directly to occipital plate without any connection from this region to the contralateral system.Advantages of this technique include easy insertion of C2 translaminar screws, presence of increased screw sizes, and exclusion of pullout forces onto the screw from neck movements. Another advantage of the technique is the median placement of the rod; i.e., thick part of the occipital bone is in alignment with axial loading. Conclusion : We believe that this technique, which could be easily performed as adjuvant to classical stabilization surgery with no need for special screw and rod, may improve distraction force in patients with low bone density.

Osteochondroma is one of the most common benign tumors of the axial skeleton, but is rarely found in the facial bones. Osteochondroma shows an irregular radiopaque lesion and chondromatic area surrounded by osteoma. It may appear different findings as calcification levels. When it develops in the long bone, it has a marked tendency in the ages from 10 to 20 years and ceases with the end of pubertal growth. However, when it develops in the condyle, it is prevalent in the third decades (average 39.2 years) and continues to develop. Lesions developed in the long bone have a predilection for men (M:F = 2:1), but for women in the mandible. Osteochondroma is differentiated from chondroma, osteochondromatosis and osteoma. Mandibular condyle osteochondroma presents asymptomatic facial swelling, rarely posterior openbite, pain during mouth opening and internal derangement of the temporomandibular joint disc due to condylar lengthening and condylar hyperplasia. The first choice of treatment of the massive osteochondroma is the surgical removal. We report osteochondroma of the mandibular condyle showing good result to treat the lesion.

Performance characteristics in pump mode of pump-turbines are vital for the safe and effective operation of pumped storage power plants. However, the head characteristics are different under different guide vane openings. In this paper, 3-D steady simulations were performed under 13mm, 19mm and 25mm guide vane openings. Three groups of operating points under the three GVOs were chosen based on experimental validation to investigate the influence of guide vane setting on flow patterns upstream and downstream. The results reveal that, the guide vane setting will obviously change the flow pattern downstream, which in turn influences the flow upstream. It shows a strong effect on hydraulic loss (power dissipation) in the guide and stay vanes. It is also found that the hydraulic loss mainly comes from the flow separation and vortices. In addition, in some operating conditions, the change of guide vane opening will change the flow angle at the runner inlet and outlet, which will change the Euler momentum (power input). The joint action of Euler momentum and hydraulic loss results in the change of the head characteristics.

In this paper, the fracture toughness evaluation of the various microstructures such as HAZ, F.L and W.M in weldment of TMCP steel which has the softening zone owing to high heat input welding was carried out by using of the small punch(SP) test. In addition, the fracture toughness with the specimen orientation of rolled TMCP steel was investigated by means of SP test and the crack opening displacement (COD) test and then was compared with that of conventional SM50YB steel. From the results of SP test for TMCP steel, it could be seen that the SP energy transition curves of three different orientation were shifted to higher temperature side in order of S, T and L. But the {TEX}$DBTT_{SP}${/TEX} of each orientation specimen did not show a lot of differences and were quite lower than those of conventional SM50YB steel. The mechanical properties of HAZ structure in weldment of TMCP steel such as hardness, SP energy at room temperature and -196$^{\circ}C$ and the upper shelf energy of SP energy transition curve were lower than those of base metal due to softening. The {TEX}$DBTT_{SP}${/TEX} of each microstructure in weldment of TMCP steel increased in order of HAZ, F.L and W.M against base metal, but all microstructures showed a quite lower {TEX}$DBTT_{SP}${/TEX} than those of SM50YB steel.

The silver nanocrystalline is widely used for biological field because of its biocompatibility and anti-microbial effect. The objective of this study was to evaluate the therapeutic efficacy of the silver nanocrystalline ointment on the temporomandibular joint (TMJ) capsulitis. Total 39 patients were included in this study and all patients were received single topical application of the silver nanocrystalline ointment (group A, n=30) or placebo ointment (group B, n=19). Measured variables were maximum mouth opening (MMO), visual analog scale (VAS) for pain, and VAS for function. In results, we could not assess any therapeutic efficacy of single application in the chronic TMJ capsulitis (p>0.05). However, the single application of silver nanocrystalline ointment showed significant improvement in MMO and VAS for pain compared to placebo effect in the acute TMJ capsulitis (p<0.05). We could not find any complications related to ointment application in both groups. In conclusion, the single application of silver nanocrystalline ointment was effective in improving patient's symptom in acute TMJ capsulitis without any noticing complications.
