Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

Conflicts between individuals are quite natural and they can act as an positive contributing factor not only to the development of an individual but also to the organization to which one belongs. But too much conflicts will always induce dissatisfaction and stresses, which will be destructive and harmful to all of them, and that is why we are always tying to seek(find) out the causes for the origination of conflicts and remedies to cope with them effectively. The present study, as the first one in a series of studies which our researchers contemplate executing, was designed to develop a measure of job satisfaction for dental laboratory technicians. One job satisfaction measure and two job satisfaction related measures, one for faithfulness for the job and the other for environmental characteristics of dental laboratory were newly developed. The newly developed measures were comprised of a total of 38 items, which were each 12 items for job satisfaction and faithfulness for the job and 14 items for environmental characteristics of dental laboratory With the aid of factor analysis for principal components and categorization of items by panel of professionals, items of each measure were grouped into 2-4 subscales. Contribution to internal consistency was the fina) criterion for an item's inclusion in a subscale. Internal consistency reliability of each item was attested through the statistical analysis on the data obtained from 55 structured questionnaires. Reliability of internal consistency of subscales in each measure of job satisfaction and faithfulness for the job ranged from 0.74 to 0.79 and 0.90-0.91 respectively. The result from this research came to draw the following conclusions. 1. Validity and internal consistency reliability of all the items of each measure was attested. 2. The newly developed measure of job satisfaction was found to be appropriate for (measuring the degree of job satisfaction of) dental technicians, as well as for (other) dental office personnels.

A correlation analysis was made to understand the interaction between the growth patterns of some craniofacial skeletal components and occlusal plane inclination. 5 angular measurements(S.a. Ar.a, Go.a, UGo.a, LGo.a), 6 linear measurements(ACBL, PCBL, RH. MBL. AFH. PFH) and OP/SN. obtained from 83 cephalometric tracing records, were selected and the relationship between the occlusal plane angle and those measurements were analyzed statistically. Ramus Height(r=-0.55), Posterior Facial Height(r=-0.41), were found to be negatively related with Occlusal Plane angle, while Lower Gonial angle(r= 0.35), Saddle angle(r= 0.24) were found to be positively related with Occlusal Plane angle(p(0.05). The results obtained from the above analysis were further assessed with stepwise regression analysis, using Occlusal Plane angle as a dependant variable, and RH, LGo.a and S.a as explanatory variables. Stepwise regression analysis revealed that all the explanatory variables were found to be significant.(p<0.05) [OP/SN] = -8.74-0.33(RH)+0.23(S.a)+0.20(LGo.a). (R²=0.44). This stepwise regression analysis explains, to some extent, the relationship between the growth patterns of some craniofacial skeletal components and the occlusal plane inclination. 1. The inclination of Occlusal Plane angle is noticeably related with the growth patterns of some craniofacial skeletal components, i.e. RH, PFH, Saddle angle and Lower Gonial angle 2. In high Occlusal Plane angle, the Ram us Height tends to be shorter, and the Saddle angle and Lower Gonial angle tend to be obtuse.

Clinically the arthritis occupies much part of musculoskeletal diseases. The arthritis is subordinate to Bi-jeung in the oriental medicine. No matter what is cause of the diseases, the lesions of the arthritis are mostly cartilages and bursa. But in process of the depravation bones, muscles, tendons, ligaments and blood are influenced and become new the lesions of the arthritis, it is important that the treatments of the oriental medicine must be objectified and we must absorb a good of the western medical treatments and understand the excellent study of the arthritis in the western medicine. This study was done to comply a reference of 56 master's theses on the cartilage of the western medicine. And these theses were classified by the college, time, treatments and topics. The following resutls were obtained in this study: 1. Whereas In the theses on the cartilages of the western medicine, Jung-ang and Catholic university have the more theses than any other universities. 2. Analysing the theses on the cartilages of the western medicine, we can classify them by the topics with the influence on the regeneration and culture of the cartilages, observation of the historical structure and the influence on the cartilages by the operation. 3. The theses of the influence on the regeneration and culture of the cartilages were the most, 48%, and the second was the influence on the cartilages by the operation.(22%) However the theses on the observation of the historical structure occupied 16%.

Background: This study evaluated the inhibitory effects of N-acetylcysteine(NAC) and methylprednisolone on lung injury in the paraquat-poisoned rat model. Methods: Sixty rats were divided into four groups(n=15 in each group) accordingly to the drug administered : group I, only intraperitoneally injected paraquat (20 mg/kg); group II, intraperitoneally injected paraquat and NAC(300 mg/kg); group III, intraperitoneally injected paraquat and methylprednisolone(60 mg/kg); and group IV, intraperitoneally injected paraquat, NAC(300 mg/kg), and methylprednisolone(60 mg/kg). On the 7th day after injection, the survival rate of experimental rats and the positive area of collagen fiber in the injured lung stained by Masson's trichroms were evaluated. Results: 1. There were no differences in the 7-day survival rates for the four groups. 2, The percent of collagen fiber for group II(6.3 ± 4.7%) was significantly decreased in comparison with that for group I (14.4±9.7%). 3. The percent of collagen fiber for Group III(13.2±5.9%) was not significantly different from that for group I(14.4±9.7%). 4. The percent of collagen fiber for Group IV(6.9±4.6%) was significantly decreased in comparison with that for group I, but was not different from that for group II. Conclusion: These results suggest that NAC protects against pulmonary fibrosis in paraquat-poisoned rats whereas methylprednisolone does not protect against pulmonary fibrosis.

T. Y. SHIM, S. H. SHIN, S. I. OH, J. I-. MUN. EMG Analysis for Investigation Muscle-Collaborated Relationship during Golf Swing. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 177-189, 2004. Kinematic and kinetic analysis using 3D Motion Capture system are common, yet there is little in the literature that discuss the relationship and coactivity between muscles during the golf swing. The purpose of this study was to describe the relationship between the employed 16 muscles during golf swing. We could observe 3 muscle patterns such as 'Line' shape, 'L' shape, and 'Loop' shape for the golf swing activity. The 'Line' shape indicates that two muscles act almost perfectly in phase, and the 'L' shape represents that two muscles act in a reciprocating manner(When one is active, the other is quiescent and vice versa). And the 'Loop' shape indicates that two muscles act sequently(After one is active, the other act). In these results, we knew the muscle patterns during golf swing is similar to the patterns during gait. And we presented it was possible to show the consistence of golf swing through the frequency analysis of muscle patterns. We believe that the results potentially useful for the golf players and coaches to analyze their performance.

p-type α-SiC(4H, 6H, 15R polytype)를 사용하여 다공질 실리콘(porous silicon; PS)의 제작방법과 유사하게 HF/H₂O/C₂H??OH 용액에서 전기화학적으로 에칭을 하여 광발광 특성을 가지는 다공질 실리콘 카바이드(porous silicon carbide; PSC)를 제작하였다. PSC의 다공질의 분포는 전류밀도가 증가할수록 증가하고 다공질의 크기는 감소하였으며 광발광(photoluminescence; PL) 스펙트럼의 분석을 통해 전극 표면에서의 산화반응은 공급되는 전자의 양과 전류밀도에 의존하며 전류밀도가 증가할수록 전극의 산화반응은 억제된다는 결과를 얻었다. Porous silicon carbide(PSC) having photoluminescence(PL) can be prepared by a technique very similar to that used in porous silicon preparation, by electrochemical etching of crystalline p-type α-SiC(4H, 6H, 15R polytype) in ?? solution. The results show that porous distribution increase with increasing of the current densities while pore size decrease with that. Through the PL spectra analysis anodic oxidation of electrode surface was dependent on the amount of provided electrons and the current densities and inhibited with increasing of the current densities.
