3D 캐릭터 애니메이션은 영화, 광고, 게임, 사이버아이돌 등 다양한 엔터테인먼트 요소로 하여 영상산업에서 중요한 위치를 차지하고 있다. 기술적인 발달로 3D 캐릭터 애니메이션은 다양한 연출과 사실적인 표현이 가능하였지만 인체 해부학적 이해가 없이 캐릭터를 제작한다면 비례와 구조에 맞지 않은 캐릭터가 제작되어 진다. 인체 해부학은 신체구조를 해부학으로 분석하여 캐릭터 모델링 제작에 많은 도움을 주고, 캐릭터 애니메이션을 제작할 때도 신체 움직임이나 얼굴표정을 정밀하게 제작할 수 있는 기본 지식이라 할 수 있다. 이에 본고에서는 인체의 구조와 인체의 비례를 살펴보고 인체 해부학적 이해를 바탕으로 3D 캐릭터 모델링과 애니메이션 제작방법에 중점을 두었다.

본 연구에서는 거머리의 미세한 해부구조를 3차원적으로 분석 가능한 방사광의 경 엑스선 이미징을 통하여 객관적 분석법 및 생체모사기술 구축을 위한 기초자료를 구축하고자 하였다. 우리는 방사광을 이용하여 거머리의 미세 구조영상을 얻을 수 있었고, 3차원적인 해부학적 분석이 가능함을 확인하였다. 또한 방사광을 통해 얻은 데이터는 내부구조의 미세조직까지 관찰 가능하기 때문에 성분 분석 및 생리적, 기능적 측면으로도 연구의 토대가 될 것으로 사료된다. 더 나아가 추후 거머리로부터 생체모사기술 연구 분야 등에 기여할 수 있을 것이라 기대된다.

Objectives Most of the acupuncture or dry needling points for trigger finger were limited around the metacarpophalangeal joint, A1 pulley, and flexor muscle tendon. Thus, this study aimed to report a case of a patient with trigger thumb which improved using dry needling on additional muscle points. Methods The author has investigated why additional points are needed including what its accompanying effects are. Dry needling and electro-dry needling have been conducted based on anatomical structure. Moreover, a follow-up observation was performed twice to evaluate if the effects of this treatment have been maintained. Treatment progress was evaluated using a numeric rating scale (NRS) and Quinnell's classification of trigger finger. Results After 28 days of treatment, NRS and Quinnell's trigger grade decreased significantly without adverse effects. The treatment effect has been maintained until follow-up observation. Conclusions Additional points are recommended for the radical treatment of trigger finger.

Purpose: The nasopalatine canal is a well-known, important anatomical structure in the anterior maxilla, but this region contains many accessory canals. The canalis sinuosus (CS) is one of these canals; it contains the anterior superior alveolar nerve, along with veins and arteries. The purpose of this study was to evaluate the CS using cone-beam computed tomography (CBCT) in patients with maxillary impacted canines. Materials and Methods: A total of 111 patients admitted to the Istanbul Medipol University School of Dentistry for the exposure, orthodontic treatment, and/or extraction of an impacted canine were included in this study. CBCT images were obtained for these patients under standard conditions. Axial, coronal, and sagittal sections were evaluated to assess the prevalence of CS, the direction and diameter of the canal, its relation with the impacted canine, and its distance from the alveolar crest. Further, possible correlations with patient gender and age were analyzed. Results: The CS could be detected bilaterally in all the evaluated tomography images. The mean canal diameter was significantly larger in males than in females(P=.001). The CS ran significantly closer to the impacted canine when the canal was located horizontally (P=.03). Variations of the canal, such as accessory canals, were identified in 6 patients. Conclusion: CS is an anatomical entity that may resemble periapical lesions and other anatomical structures. Evaluation with CBCT prior to surgical procedures in the anterior maxilla will help to prevent overlooking such anatomical structures and to decrease possible surgical complications.

Purpose: The mental foramen (MF) is an important anatomical structure during local anesthesia and surgical procedures in terms of achieving effective mental nerve blocks and avoiding injuries to the neurovascular bundles. Thus, understanding the anatomic features of the mandibular canal and accessory mental foramen in Korean could contribute to the surgical anatomic assessment. This study was to elucidate frequency, position and course of AMF (accessory mental foramen) in Korean using 3D cone beam computed tomography. Materials and Methods: The CBCT (Conbeam computed tomography) DICOM data (Alphard, Asahi, Japan) from 540 patients in korean were analyzed. We investigated images of 3D CBCT using Ondemand (CyberMed, Korea) software program on the incidence and anatomical characteristics of accessory foramen. Results: The accessory mental foramina were found in 17 patients. Accessory mental foramina exist predominantly in the apical area of the second premolar and posteroinferior area of the mental foramen. The accessory branches of the mandibular canal showed common characteristics in the course of gently sloping posterosuperior direction in the buccal surface area. The size of most AMF was obviously smaller than that of MF. Conclusion: We could identify frequency, position and course of AMF (accessory mental foramen) by the anatomical study of the accessory mental foramen using 3D cone beam CT in Korean.

This study was carried out to identify anatomical characteristics of the individual bones of the cranium of the Korean native goat. The pars lateralis and pans basilaris of the os occipitale were fused each other, whereas the squama occipitalis articulated with the pars lateralis, forming the sutrue. The sinus sphenoidale was formed in the corpus ossis presphenoidalis. The os prietale was observed as a single bone. In the os frontale, an fossa innominatum was found ventrolateral to the root of processus cornualis, and the orificium orbitale canalis supraorbitalis was also formed on the pars orbitalis. The meatus temporalis was formed in the medial side of the pars squama of the os temporalis. The lamina cribrosa of the os ethmoidale was membrane-like structure with many foramina. The labyrinth ethmoidalis was composed of four endoturbinalia and ten to twelve ectoturbinalia.

1. The physical and anatomical properties investigated in this study are the ones, which may give more effect on absorption of preservatives, such as variation of annual ring, specific gravity, shrinkage, E.M.C. of desorption and adsorption at 70 percent relative humidity condition, general and minute properties of wood. 2. On this study, the positive effects of wood structure, in particular, the appearances of tyloses in vessel element upon the absorption of creosote were observed. 3. Thirteen percent sodium chloride solution treatment and boiling hot water treatment have shown poor results to improve the preservative absorption characteristics of tested species however, some slight difference between treated and control could be seen. (see Tables 6 and 7).

Schizophrenics suffer not only psychotic symptoms but also cognitive deficits such as an attentional difficulty, memory impairment, poor abstraction, etc. These cognitive abnormalities have been reported to be significantly related to the social and occupational outcome in schizophrenia. Thus, it is important to explore the cause and pathophysiology for the cognitive abnormalities in patients with schizophrenia. In this regard, hippocampus is one of the most promising brain areas to search for the clue because it is closely involved in memory related function. In fact, during the past several decades, there have been extensive studies supporting hippocampal abnormalities as a cause of schizophrenia in both clinical and preclinical field. In this review, basic anatomical knowledge about hippocampus and major findings of preclinical and clinical studies which investigated the correlation between schizophrenia and hippocampus were highlighted. The contents are 1) anatomical structure of hippocampus, 2) neuronal pathway and receptor distribution in hippocampus, 3) function of hippocampus, 4) hippocampal animal model for schizophrenia, 5) hippocampus-related studies on antipsychotic drugs, and 6) clinical studies in hippocampus in patients with schizophrenia.

Therapeutic injections into the craniofacial region can be a complex procedure because of the nature of its anatomical structure. This technical note demonstrates a process for creating an extra-oral template to inject therapeutic substances into the temporomandibular joint and the lateral pterygoid muscle. The described process involves merging cone-beam computed tomography data and extra-oral facial scans obtained using a mobile device to establish a correlated data set for virtual planning. Virtual injection points were simulated using existing dental implant planning software to assist clinicians in precisely targeting specific anatomical structures. A template was designed and then 3D printed. The printed template showed adequate surface fit. This innovative process demonstrates a potential new clinical technique. However, further validation and in vivo trials are necessary to assess its full potential.
