The purpose of this study was to investigate the interrelationship between temporomandibular joint disorders, and the condyle size and angle of the posterior slope of the articular eminence. The subjects used in this study were 100 patients with temporomandibular joint disorders and 100 volunteers with normal temporomandibular joints. All the patients and the volunteers were subjected to take panoramic and temporomandibular radiographs for the morphologic evaluation. This films were traced, measured, and analyzed. The data were processed with SPSS/PC+package for statistical analysis. The obtained results were as follows : 1. The posterior slope of the articular eminence in the group of temporomandibular joint disorders was larger than that in the normal group (p<0.05). The mean articular eminence angle was 31.6。±6.3 in the group of temporomandibular joint disorder, and 29.9。±8.4 in the normal group. 2. There were no statistically significant differences in the discrepancies of the left and right articular eminence angular measurements between the group (p>0.05). 3. There were no statistically significant differences in the condylar ratio between the groups (p>0.05). 4. There were no statistically significant differences in the discrepancies of the left and right ramus length measurements between the groups (p>0.05). 5. The relative size of condyle to fossa in the group of temporomandibular disorders was smaller than that in the normal group(p<0.05).

방언은 지역적 특징을 나타내는 언어이며 강세, 지속시간, 억양에 따라 그 차이가 다르게 나타난다. 특히 대구-경북방언은 표준어와 달리 독특한 억양을 가지며, 경기방언과 비교하면 낱말에서 음절마다 그 강도가 서로 다르다. 최근 지역 간 교류가 활발해지면서 방언 간 언어적 특징은 그 차이가 좁혀지고 있으나 여전히 고유한 면이 남아있다. 이 연구는 대구-경북에 거주하는 20∼25(22.7±3)세 사이의 성인 10명(남:녀=5:5)을 대상으로 하여, 방언 특징을 음절 강도를 통해 확인하고자 한다. 대구-경북 방언 사용자들은 두 번째 음절의 강도가 크게 나타났고, 타향어 발화시 음절 간 강도가 작게 나타났다. 그러나 음절 간 강도는 여성 화자가 남성 화자보다 큰 차이를 보였다. A dialect is a form of a language that is spoken in a particular area and it shows different stress, duration time and intonation. Especially Daegu-Gyeongbuk dialect has unique intonation. Compared to Gyeonggi dialect, each syllable in the word has different stress. Recently, Human network between regions was increased. For this reason, inter-regional characteristics of dialect are reduced. however, there still remains unique features. 10 Daegu-Gyeongbuk dialect users (M:F=5:5, 22.7±3 years of age) were participated. Syllable intensity through the dialect characteristics want to confirm. Daegu-Gyeongbuk dialect users showed significantly the intensity of the second syllable, the intensity of syllables from non-native dialect was lower. The intensity of syllables the female speaker than male speakers showed a significant difference.

현재 이동 전화 및 무선 LAN을 이웅하여 휴대인터넷을 즐기는 사용자가 많다. 하지만 이동전화는 이동성은 좋지만 전송속도가 느리고 무선 LAN은 전송속도는 좋으나 이동성이 나쁜 한계가 있다. 이런 단점을 극복하고자 나온 것이 WiBro이다. WiBro는 Wireless Broadband Internet의 줄임말로 IEEE 802.16e에 기반을 둔 한국 표준이다. WiBro에서는 60km/h의 속도로 1Mbps 이상의 전송 속도가 요구되므로 channel 특성에 강한 ECC (Error Correcting Code)가 중요핟. 이에 WiBro에서는 Convolution Turbo Code (CTC)를 사용하고 있으며, Hybrid-ARQ와 같은 유동적 재전송 Code를 사용한다. 본 논문에서는 이러한 강력한 Channel Codec과 TDD 방식의 WiBro 규격을 만족하기 위해서 기존의 Max-Log-MAP algorithm을 변형하여, H/W의 복잡도를 줄이고, Low power을 가능하게 하는 구조를 제안한다.

The purpose of this study was to evaluate the stress patterns developed in supporting structures by removable partial denture with an extracoronal and an intracoronal rigid attachment. The mandibular removable partial dentures with Mini S-G (extracoronal) and C-M Box (intracoronal) attachment were constructed. Under 100N, 200N of vertical and 25N, 50N of lateral loads at the 1st and 2nd lower molar, stress distribution patterns and displacement were analyzed with three dimensional finite element method. The result were as follows: 1. There was no apparent difference in the patterns of stress distribution between rigid extracoronal and rigid intracironal attachments. 2. In case of the single abutment tooth with the rigid intracoronal attachment, it was not proper to preserve the abutment tooth. 3. With splinted abutments, the stress was distributed through all the root surface of both abutments. With single abutment, the stress was concentrated on the distal root surface of abutment. 4. With splinted abutments, there was not clear difference in the patterns of stress distribution with or without lingual bracing part. 5. In case of the single abutment tooth with the rigid intracoronal attachment and cantilever. More stress was concentrated around the abutment tooth with the lingual bracing part under loaded concentrated force and the abutment tooth without the lingual bracing part under loaded distributed force. 6. In case of the splinted abutments with the rigid extracoronal and intracoronal attachment, the denture base was displaced posteriorly and inferiorly when the force was applied. 7. In case of the single abutment tooth with the rigid intracoronal attachment, there was little displacement at the denture base.

This study was designed to compare the ability of human periodontal ligament cell viability according to different storage methods, storage time and temperature, and to evaluate the osmolality and pH of the storage media. In the present investigation, media tested for their ability of PDL cell were HBSS, milk, milk contained antibiotics, saliva, ion drink, saline. Time interval was 2 min, 5 min, 10 min, 30 min, 60 min, 120 mi, and storage temperature was 4。C and room temperature. The viability of PDL cells stored for these media was determined by the trypan blue dye exclusion test. Viable (non-stained) and non-viable (stained) cells were counted in a hemocytometer. The pH of storage media were evaluated at 4。C and room temperature. The osmolality of the samples was analysed in an Osmometer, 3D-Ⅱ model. The results were as follows: 1. PDL cell viability was declined in the sequence of DMEM, HBSS, milk contained antibiotics, milk, saline, saliva, ion drink, Distilled water(p<0.01). 2. PDL cell viability was more depended on pH than Osmolality of storage media. 3. PDL cell viability was better at 4。C than room temperature(p<0.01). 4. PDL cell viability was decreased with time(p<0.01).
