The study was undertaken to ascertain the speech defect of patients with malocclusion, especially of openbite patients, by means of the spectral analysis method. The experimental group was composed of ten female openbite patients and their mean age was 13.8 yrs. The control group was also composed of ten female girls and their mean age was 13.7 yrs. As for the speech material, eight Korean monophthrongs and two Korean fricatives and two affricatives were used. Speeches were recorded and then analyzed by a Kay 7800 digital sonagraph. Formant frequency level or range was used as a phonemic parameter. The results were as follows: 1. Among Vowels /a:/ : $F_1,\;F_3\;and\;F_1/F_2$ showed abnormality. /o:/ and $/w:/:F_2,\;F_2-F_1\;and\;F_1/F_2$ showed abnormality. 2. Among Consonants /S/ and /h/ : The upper and lower borders of the frequency range showed abnormality. (equation omitted) : The lower border of the frequency range showed abnormality. $/C^{h}/$ : The upper and lower borders of the frequency range and concentration point showed abnormality.

Modern Bulgarian nationalists aspired towards incorporating the self-identified Bulgarian lands into the Bulgarian state. The Treaty of San Stefano ending the Russo-Turkish War of 1877-78 tantalizingly achieved these so-called national ideals. Great Power diplomacy quickly diminished Bulgaria's borders and international legal status with the 1878 Treaty of Berlin, exacerbating nationalist grievances. Bulgaria would expand vast resources to restore the San Stefano borders until Balkan Communist authoritarian regimes eventually suppressed the Macedonian issue as a foreign policy subject. Sofia's policy towards its neighbor has been overdetermined by the efforts of successive Bulgarian governments to institutionalize post-communist Bulgaria's own national identity. Bulgaria's integration into so-called Euro-Atlantic structures, i.e., NATO and the EU, had been the primary strategic objective of the Bulgarian authorities since the end of the Zhivkov regime. North Atlantic community security policy aims in response to the earliest post-Cold War foreign policy crises in the Western Balkans framed the parameters of Bulgarian diplomacy. The stabilization of FYROM in 2001, followed by Bulgaria's 2007 EU accession, led to Bulgarian nationalist values become more salient in Bulgarian politics and foreign policy. Sofia-Skopje relations are a test case for the effects of Europeanization on interdependent Balkan ethno-sectarian nationalisms and state territorial institutional development.

It is widely known that the Bugis people, originally from South Sulawesi, have been migrating to many places, including both the Indonesian and Malaysian sides of the borders today. The translocal and transnational movements of the Bugis people, especially to North Kalimantan of Indonesia and Sabah and Johor of Malaysia, have occurred in several waves, particularly during the 17th century, around 1965 and from 1980 to the present. The fall of the kingdom of Somba Opu in South Sulawesi and the rise Dutch colonial power have been the triggers for the early movement of the Bugis to both the Indonesian and Malaysian borders. This was followed by the second push of the Islamic rebellion in South Sulawesi, around 1965, creating another big wave of Bugis movement. The most recent one has been mainly due to economic reasons. These different phases of the movements, as well as the dynamic interplay of various aspects, such as citizenship, ethnic, and sub-ethnic groupings, practicing of cultural traditions and keeping the language, to mention a few, have contributed to the process of the construction of the multiple identities of the Bugis. Indeed, the Bugis people are no longer identified or identify themselves as a single group, but rather have fluid and contesting identities. This paper will discuss three main issues: the history of the translocal and transnational movements of the Bugis to North Kalimantan, Sabah and Johor; the process of adaptation to these new places; and the construction of Bugis identities.

The suboccipital triangle (ST) is a clinically relevant landmark in the posterior aspect of the neck and is used to locate and mobilize the horizontal segment of the third part of the vertebral artery before it enters the cranium. Unfortunately, this space is not always a viable option for vertebral artery exposition, and consequently a novel triangle, the inferior suboccipital triangle (IST) has been defined. This alternative triangle will allow surgeons to locate the artery more proximally, where its course is more predictable. The purpose of this study was to better define the anatomy of both triangles by measuring their borders and calculating their areas. Ethical clearance was obtained from the University of Pretoria (reference number: 222/2021) and both triangles were subsequently dissected out on both the left and right sides of 33 formalin-fixed human adult cadavers. The borders of each triangle were measured using a digital calliper and the areas were calculated using Herons Formula. The average area of the ST is 969.82±153.15 mm², while the average area of the IST is 307.48±41.31 mm². No statistically significant differences in the findings were observed between the sides of the body, ancestry, or sex of the cadavers. Measurement and analysis of these triangles provided important anatomical information and speak to their clinical relevance as surgical landmarks with which to locate the vertebral artery. Of particular importance here is the IST, which allows for mobilisation of this artery more proximally, should the ST be occluded.

최근 대용량 의료영상 데이터로부터 인체 기관 또는 질환 부위 추출을 위한 영상 분할 기법이 매우 다양하게 제안되고 있으나, 뇌와 같이 다중 구조를 가지면서 구조간 경계 구분이 어려운 영상의 구조적 분할에는 한계를 가진다. 이를 위해 주로 복셀을 유한 개의 군집으로 분류하는 군집화 (clustering) 기법이 이용되나 이는 개별 복셀 단위의 연산을 수행함으로 인해 잡음의 영향을 받는 제한점이 있다. 그러므로 잡음의 영상을 최소화하고 영상 경계를 강화시키는 향상기법을 적용함으로써 보다 견고한 구조적 분할을 수행할 수 있다. 본 연구에스는 뇌 자기공명영상에 대하여 백질(white matter), 회백질(gray matter), 뇌척수액(cerebrospinal fluid)의 내부 구조를 효율적으로 추출하기 위한 필터링 기반 군집화에 의한 구조적 분할 기법을 제안한다. 우선 구조간 경계를 강화하고 구조 내 잡음을 약화시키기 위해 응집성 향상 확산 필터링(coherence enhancing diffusiion filtering)을 적용한다. 또한 이 과정을 통해 강화된 영상에 퍼지 c-means 군집화 기법을 적용하여 각 복셀이 속하는 구조에 해당하는 군집의 인덱스를 할당함으로써 구조적 분할을 수행한다. 제안된 구조적 분할기법은 기존의 가우시안 또는 일반적인 비등방성 확산 필터링과 군집화 기법을 적용한 기법에 비해 전문가의 수동분할 결과와의 일치 비율에 의한 분할 정확도를 향상시킴을 보였다. 또한 경계 부분에 있어서의 세밀한 분할을 통해 재생산 가긍하고 사용자 수동후 처리를 최소화할 수 있는 결과를 제시함으로써 형태적 뇌 이상 진단을 위한 효율적인 보조 수단을 제공한다.

"베니스의 상인"의 샤일록은 악한이자 악마로서 간주되거나 기독교 사회에서 부당하게 박해당하는 피해자로 간주되어왔다. 신역사주의와 문화유물론 이후의 비평에서는 문학 텍스트나 문학 비평의 영역에서 배제되었던 타자의 문제를 새롭게 부각시켜서 유태인 샤일록을 베니스의 기독교 사회에서 억압당하는 인종적, 종교적, 경제적 타자로 해석해냈다. 이 논문은 크리스테바의 비체화 이론을 토대로 타자로서의 샤일록이 어떻게, 왜 비체로서의 샤일록이 되었으며 어떤 방식으로 비체가 되었는지 살펴보는 것을 목표로 한다. 샤일록은 베니스의 기독교 사회가 깨끗하고 동질적인 정체성을 유지하기 위해 그어놓은 경계선에 의해 주변으로 밀려난 타자, 즉 비체가 되었다. 샤일록을 비체로 만드는 장치인 경계선에는 게토와 특수한 유태인 복장 같은 눈에 보이는 경계선과 종교적, 경제적 측면의, 눈에 보이지 않는 경계선이 있다. 그러나 샤일록은 빌려간 돈을 제날짜에 갚지 못한 앤토니오에게 1파운드의 살을 떼어달라고 요구함으로써 이런 경계선을 넘어 기독교 사회의 정체성을 위태롭게 만든다. 경계선을 넘으려는 샤일록의 시도는 1파운드의 살에 대해 다른 해석체계를 제시한 포오샤에 의해 저지당하고 샤일록은 다시 비체의 자리로 추방된다. 비체로서의 샤일록에 대한 비평은 타자의 수동적인 측면뿐만 아니라 항상 경계를 벗어나서 지배 체제에 도전하고자 하는 욕망을 강조한다.

A new video watermarking scheme with robustness against collusion and synchronization attacks is presented. We propose to embed only a few copies of the watermark along the temporal axis into frames, which are located at the borders of each two different plotlines of the video. As a result, each change of the video plotline is transformed into pulse, which is used for watermark embedding and extraction. In addition, since we embed a watermark only into a small number of frames, the distortions of the video are reduced to minimum. Experimental results show the robustness of the proposed scheme.

Pityriasis rosea in a 2-month old pig is described. Lesions were confined to the abdomen and groin. They consisted of raised, erythematous papules with distinct borders. Microscopic examination of the lesions revealed a nonspecific dermatitis with acanthosis, moderate infiltration of mononuclear cells and eosinophils in the upper dermis. The known occurrence of the disease will help differentiate the condition from other dermatoses.

To study the effect of prostglandin $E_2$ and evening primrose oil on orthodontic tooth movement in rats, one hundred and sixty rats were divided into four groups of 40 rats each. One group, injected with saline on the palate subperiosteally, served as a control group. A second and third group were injected subperiosteally on the palate with $PGE_2$ $10{\mu}g$ and evening primrose oil 10mg respectively. The fourth group was given indomethacin $20{\mu}g/m{\ell}$ orally by water bottle. The maxillary first molar was moved mesially from the incisors using a 50gm force rubber band. In each group at the 1, 2, 3, 5, and 7th day, 4 rats were examined by light microscope, and 4 by electron microscope. The obtained results were as follows: 1. Osteoclastic activity was maximum at the 3rd day in the $PGE_2$ group on the interradicular alveolar bone of the first molar, followed by the evening primrose oil group, control group, and indomethacin group. 2. Root resorption and vacuolar changes were maximum in the $PGE_2$ group. 3. At the 3rd day of the $PGE_2$ group, the osteoclasts showed well developed ruffled borders and clear zones. At the same day, the evening primrose oil group also showed well developed ruffled borders and clear zones, but less than the $PGE_2$ group. 4. At the 3rd and 5th day of the $PGE_2$ group, fibroblasts showed phagocytized fragmented collagen fibers in the cytoplasm. At the 7th day of the $PGE_2$ group, fibroblasts showed collagen fibers forming at the cell membrane surface.
