저자등은 악교정수술후에 발생하는 희귀성향에 관한 연구를 위하여 계명대학교 의과대학 치과학교실에 내원하여 하악전돌증으로 진단되어 하악후퇴술을 받은 7명의 환자를 대상으로 하여 수술전, 후의 경조직의 변화를 계측, 분석하여 다음과 같은 결과를 얻었다. 수술직후 Gn(H)는 평균 8.2mm 후방이동되었고 SNB는 평균 4.4 감소하였다. SNB는 장기간 경과후 수술직후보다 평균 0.9 증가되었으며 21.1%의 희귀율을 나타내었다. Gn(H)는 장기간 경과후 수술직후보다 6례에서 평균 1.3mm 전방희귀되었으며 나머지 1례에서 4mm 후방이동되었다. SN-MP 및 gonial angle 은 장기간 경과후 수술 직후보다 각각 평균 2.2 ,5.8 증가되었다. Gn(V)는 장기간 경과후 수술직후와 비교하여 변화가 없는 경우가 4례, 증가 2례, 감소 1례로 나타났다. 상하악 중절치는 장기간 경과후 수술직후보다 각각 순측 혹은 설측으로 경사되었다. This study was undertaken to examine relapse tendency after mandibular setback. Seven cases were selected from patients who underwent orthodontic treatment and mandibular setback surgery in our department. The serial lateral cephalogram of each patient were obtained and analyzed: The result were as follows; 1. By operation, Gn(H) moved backward (average 8.2mm), SNB angle decreased(average 4.4˚). 2. When the long term follow-up measurements were compared with the immediate postop, mesurements. ·SNB angle increased on average by 0.9˚and relapse tate was 21.1%. ·GN(H) returned foward on average by 1.3mm in 6 cases, moved backward by 4mm in 1 case. ·SN-MP and gonial angle increased on average by 2.2˚, 5.8˚respectively. ·Gn(V) stayed unchanged in 4 cases, increased in 2 cases, decreased in 1 case. ·Upper and lower incisors slightly moved labially or lingually.
A Discourse-Pragmatic Explanation for Extraposed Relative Clauses in English
Bu Seon Song 한국현대영어영문학회 2009 현대영어영문학 Vol.53 No.4
This paper reviews and discusses the discourse function and constraints on extraposed relative clauses in English. Researchers have claimed that extraposition of relative clauses is not a function of syntax, but of pragmatics. Communicative functions of unextraposed and extraposed relative clauses are presented. A discoursal constraint proposed by Takami (1999) is examined to account for the acceptability vis-a-vis the unacceptability of the extraposed relative clauses. This study strongly shows that extraposition of relative clauses is highly sensitive to the flow of information in discourse, and should be dealt with from issues of semantics, pragmatics, and the entire interactional dimension of the communicative situation.

Purpose: Lennox-Gastaut syndrome (LGS) is one of the most severe epileptic encephalopathies and frequently patients with this syndrome respond poorly to antiepileptic drugs. The aim of this study was to evaluate the treatment outcomes of vagus nerve stimulation (VNS) in LGS patients with drug-resistant epilepsy. Methods: We analyzed the clinical files, collected over 5 years, of children with LGS who received VNS treatment. Results: Seven children were included in this study (four males, three females; mean age of VNS insertion 12.4±3.5 years). All the patients had generalized tonic seizures and there were various other seizure types including myoclonic seizures, atonic seizures, and atypical absence seizures. Although two patients had normal imaging, five patients had abnormalities on imaging, including pachygyria, cortical dysplasia, kernicterus, and a chromosomal anomaly. Comparing the baseline seizure frequency to the frequency after the VNS surgery, the seizure frequency at the last follow-up showed a decrease of 57.2% (0% to 100%) on average (P=0.028) and one patient achieved seizure free status. Only two children were given additional antiepileptic drugs with the aim of managing their seizures. There was no mortality or complications related to the VNS therapy except one case requiring intensive care unit admission due to pneumonia. Comparing the results before and after VNS surgery, the VNS therapy also had a tendency to have a positive effect on quality of life (P=0.066). Conclusion: In LGS patients with drug resistant epilepsy who are not candidates for a corpus callosotomy or resective surgery, VNS could be an effective, low-risk adjunct therapy for decreasing seizure frequency.
