Background and Objectives : Several speech manifestation are observed in temporal lobe epilepsy(TLE). We studied the frequency of ictal speech manifestations and their localizing and lateralizing value in TLE. Methods : We reviewed 379 seizures recorded on videotape in 135 patients who underwent temporal lobectomy for intractable TLE. We divided patients into group A(n=75) who became seizures free after surgery, and group B(n=60) who were only slightly benefited or unchanged after surgery. Speech manifestations were classified as normal speech, vocalization, or abnormal speech. Abnormal speech was subdivided into speech arrest, dysarthria, dysphasia, or nonidentifiable speech. Results : Speech manifestations occurred in 70(18.5%) seizures of 28 patients. Forty eight seizures of 20 patients were observed in group A, and 22 seizures of 8 patients were observed in group B. In group A, 25 seizures of 11 patients were originating from dominant hemisphere, 23 seizures of 9 patients from nondominant hemisphere. In group B, 13 seizures of 5 patients were originating from dominant hemisphere, and 9 seizures in Lt. side and 6 seizures in Rt. side, respectively) of group A(P>0.05), and eleven seizures of 4 patients(8 seizures from Lt. side and 3 seizure from Rt. side) in group B(P>0.05). Normal speech was observed only seizures from Rt. side in both groups(3 seizures in 1 patient, each group). Dysphasia occurred only in seizures originating from Lt. side. Nonidentifiable speech occurred in 22 seizures of 9 patients(11 seizures from each side) in group A(P<0.01), and 3 seizures of 1 patient occurred only from Lt. side in group B. Conclusion : Ictal speech manifestations were not uncommon(18.5%). All kinds of ictal speech manifestations except normal speech have no reliable lateralizing and localizing value in TLE. Normal speech could be a good indicator of seizure originating from nondominant hemisphere.

The progenies of 108 combination crossed among Korean Lines and resistant lines introduced from Italy and Japan were tested with innoculation of p.capsici in order to select the multi-resistant lines to red pepper diseases 5 resistant lines to TMV, 7 resistant lines to PVY, 3 resistant lines to nematode and 10 resistant lines to p.capsici were selected among 241 lines introduced from Naples university in Italy 149 lines showed susceptibility to Japan race of p.capsici among the 241 line, 82 partial resistant lines and 10 resistant lines were selected in Tokuku seed company in Japan, respectively. The 11 combinations among 108 combinations crossed between Korea lines and the resistant 10 lines showed resistance to Korean p.capsici. The 12 combination with TMV resistance and p.capsici according to the result of immoculation test. Therefore, the possible result of improvement for the multi-resistant variety to PMV and p.capsici was obtained.

Overlap에서의 유도 초음파 산란에 대한 정량적인 예측을 가능하게 하고 유도 초음파를 이용한 효율적인 NDE가 overlap 구조물들에서 수행되어지기 위해서 혼합형 경계요소법을 이용하였다. 다양한 joint를 가진 다층 구조물에서 적절한 모드를 선택하고 주파수를 조정함으로써 수행되어졌다. 두께의 차이에 의한 전달과 반사의 값들의 변화를 살펴보고 정해진 형상에서의 주파수 증가와 다수의 파동을 포함한 긴 overlap 길이를 가진 모델에 대한 산란 선도의 변동을 보여주게 된다.

This paper premises that the teacher's performance is different depending on the subject matter in teacher education. The objects of this paper are as follows. At first, this research is reviewed how curriculums of three type teachers education colleges - eleven national universities of education. K national university of education, E womans university - in korea is operating. Secondly, Teacher's performance is interviewed by 26 teachers in 9 elementary schools. They had studied subject matters in each other colleges and universities for elementary teachers. Data is analyzed by triangulations. The results showed that 11 national university of education demands high a grades for student in order to get the certification of teacher. Those of both teachers colleges of university is low. But pre-service subject matter education does not satisfy all of teachers. They assert that curriculums are changed not theory but practical. methods. This study appears that teachers are cultivated the knowledge and teaching method of subject matter in pre-service education.

Background: The effi cacy of routine second-look endoscopy in acute non-variceal upper gastrointestinal(UGI) bleeding has been evaluated in several randomized, controlled trials that yielded disparate results. It may be more optimally performed in selected patients at very high risk of rebleeding. This study aims to analyze the clinical and endoscopic factors that contribute to intractable endoscopic hemostasis and to determine the optimal role of second-look endoscopy. Methods: Prospectively collected UGI bleeding registry data was reviewed and data from 464 patients who underwent UGI endoscopy for acute non-variceal UGI bleeding from 8 hospitals in Korea between February 2011 and December 2013 were analyzed. Signifi cant predictive factors (P < 0.05) of intractable endoscopic hemostasis in univariate analysis were entered in a multivariate logistic regression analysis. Results: Successful hemostasis was achieved in 394 patients by using initial endoscopic procedures. Seventy patients at the second-look endoscopy were considered intractable or insuffi cient to the initial endoscopic hemostasis, and they required second endoscopic hemostasis. Univariate analysis signifi cantly related intractable endoscopic hemostasis with large amount of transfusion (=5 units), Glasgow-Blatchford score, Rockall score, Forrest bleeding type Ia and degree of initial endoscopic hemostasis. Multivariate analysis showed that large amount of transfusion and Rockall score were only predictive factors of secondary endoscopic hemostasis. Conclusions: Large amount of transfusion and Rockall score are identifi ed as independent risk factors associated with intractable initial endoscopic hemostasis in patients with acute non-variceal bleeding. Second-look endoscopy after initial endoscopic hemostasis in these patients is not routinely indicated and be reserved for selected patients with high risk of rebleeding.
