The purpose of this study was to find what are the effects of festival participant`s novelty seeking to involvement intention and satisfaction. A survey design was adopted to collect the required information and a random sampling approach was utilized to select the respondents(N=220) at Namwon herb festival. SEM(Structural equation modeling) was used to examine relationship among novelty seeking, involvement intention, and satisfaction. We found the novelty seeking has a positive effect to the involvement intention(standard regression weight=0.375, t=4.120, p<0.01) and to the satisfaction(standard regression weight=0.440, t=5.096, p<0.01). Also, the involvement intention has a positive effect to the satisfaction(standard regression weight=0.267, t=3.397, p<0.01). The findings lead to an improved understanding of the interrelationship among novelty seeking, involvement intention and satisfaction in the context of festival.

Purpose: The purpose of this study was to evaluate the efficacy of preoperative parenteral iron sucrose therapy in patients with postoperative anemia following total knee arthroplasty. Materials and Methods: We retrospectively reviewed 30 patients who had postoperative anemia and who had undergone total knee arthroplasty from March 2008 to November 2008. Those patients agreed on treatment with preoperative parenteral iron sucrose therapy. The other 30 patients without iron sucrose administration were selected as a control group from January 2007 to February 2008. In this study, age, gender, the preoperative and postoperative values of hemoglobin, the operation time, the amount of bleeding, the amount of transfusion, the frequency of transfusion, postoperative infection and the length of the hospital stay were evaluated and statistically compared. Postoperative complications were also assessed. Results: Ant complications due to the administration of iron sucrose were not observed. At 48 hours postoperatively, the mean hemoglobin of iron sucrose administration group was 9.4g/dL and that of the control group was 8.7g/dL (p=0.008). Homogenous transfusion was done for 17 cases in the iron sucrose administration group and for 22 cases in the non-iron sucrose administration group, but among these groups, the results were statistically insignificant. The amount of homogenous transfusion for each patient who underwent iron sucrose administration is 1.3 units and this was 1.7 units for each patient who underwent non-iron sucrose administration. No statistical differences were observed between the groups in this study. Conclusion: Parenteral iron sucrose administration in patients following total knee arthroplasty was not efficacious for preventing immediate postoperative anemia.

목적: 3주 이상 지연 발현된 전위된 소아 상완골 외과 골절에 대해 관혈적 정복 및 내고정술이 가능한지 그리고 최대 언제까지 치료가 지연되어도 골 이식 없이 관혈적 정복 및 내고정이 가능한지를 알아보고자 한다. 대상 및 방법: 3주 이상 지연 발현되었고 2.5 ㎜ 이상 전위된 소아 상완골 외과 골절에 대해 관혈적 정복 및 내고정술을 시행한 8예를 대상으로 하였다. 결과: 임상적 치료 결과는 우수가 6예, 양호가 2예였다. 수술 후 불유합이나 무혈성 괴사 같은 심한 합병증은 전 예에서 관찰되지 않았으나 2예에서 경도의 물고기-꼬리 변형과 외과 골편의 과성장으로 인한 경도의 운반각 소실이 있었다. 결론: 지연 발현된 소아 상완골 외과 골절에서 무혈성 괴사의 위험성 없이 관혈적 정복을 시행할 수 있는 허용 기간으로 3주는 너무 짧다고 생각되며, 최대 5주 혹은 그이상도 수술적 치료를 통하여 양호한 결과를 얻을 수 있을 것으로 생각된다. Purpose: To determine whether late open reduction and internal fixation (ORIF) of a lateral condylar fracture (LCF) after 3 weeks is possible, and to determine the latest time for ORIF without a bone graft. Materials and Methods: Eight children underwent late ORIF (>3 weeks) of a displaced LCF (>2.5 ㎜) of the humerus between 3 weeks and 5 weeks after injury. Results: Clinically, results were excellent in 6 cases and good in 2 cases. There was no serious complication, including nonunion and avascular necrosis (AVN), though 2 cases had a slight fishtail deformity and mild carrying angle loss due to overgrowth of the lateral condyle fragment. Conclusion: We believe that 3 weeks is too short to deny open reduction and anatomic reduction for fear of AVN of a late presented lateral condyle fracture of the humerus. The latest time for ORIF in late presented LCF in children is around 5 weeks, and surgical treatment may even be possible after greater delays.

This dissertation purports to examine the relationship between the attitudes before and after tour to Korea for the Japanese tourists. In specific, we tried to verify the relationship between their evaluations of cultural-tourism - products(C.T.P.) attribute and travel-agency service(T.A.S) as a product. We explored how the manipulative variables affect the T₁, (before visit) and T₂(after visit). As a result of the research, we found that the tourists who have positive attitude towards CTP and TAS at T₁. were intended to repurchase the CTP. And those who satisfy the TAS were intended to repurchase TAS as well. The factors related to CTP at the T₂. were analyzed and the results depicted that after visiting Korea their perceptions on the evaluation of CTP and TAS were par with the one of before visiting Korea as much same as the point of T₁ The tourists who were satisfied with CTP, had a propensity to repurchase the CTP. And also the tourists who are satisfied with TAS, are positively related to repurchase TAS. However, there existed no significant crossover effect which at the point of T₁, the satisfaction on CTP did not effect to repurchasing intention for TAS while the satisfaction on TAS did not influenced to repurchasing intention for CTP. Finally entire results of T₁, through T₂ which handled the relationship of other CTP's consuming factors, depicted that the satisfaction on CTP affected to repurchasing intention at the T₁ point as well as affected to repurchasing intention at the T₂ point. The repurchasing intention of CTP at the point of T₁, was important effect on that of the point of T₂. As a result, We found that the manipulated variables worked between the T₁ and T₂.

Pulsed laser deposition is a very efficient technique for fabricating thin films of complex compounds. In the present work, $Bi_2O_3$-MgO-ZnO-$Nb_2O_5$ (BMZN) pyrochlore thin films were deposited on platinized Si substrates at various temperatures by using pulsed laser deposition technique. These films have been characterized by X-ray diffractometer (XRD), atomic force microscopy (AFM) to investigate their structural, morphological properties. MIM structure was manufactured to analyze di-electrical properties of BMZN thin films. XRD results reveal the thin films deposited at less than $400^{\circ}C$ show only amorphous phase, the crystallized thin films was observed when the thin films were prepared temperature at above $500^{\circ}C$. From AFM, it was known that the thin film grown at $400^{\circ}C$ is the densest. Dielectric constant increased with increasing temperature up to $400^{\circ}C$ at 100 kHz and dramatically decreased at the higher temperature. A aspect of dissipation factor was the exact opposite of dielectric constant. BMZN thin films grown at $400^{\circ}C$ exhibited a high dielectric constant of 60.9, a low dissipation factor of 0.007 at 100 kHz.

The purpose of this study was to evaluate the clinical and radiologic result of arthroscopic anterior cruciate ligament (ACL) reconstruction using an Achilles tendon allograft. Fifty three patients out of 66 patients, who were performed arthroscopic ACL reconstruction between January 2004 and May 2006 at our institute, were followed up at least more than 1 year 6 months. Among them, sixteen patients underwent second look arthroscopy. The average Lysholm score was improved from preoperative 51.2 to postoperative 84.9. On Lachman test, 45 cases were converted to negative. On Pivot shift test, 46 cases were converted to negative. The anterior laxity test with Telos(R) on 30 lb was 10.3 mm in average at preoperative stage and was decreased to 2.9 mm in average at postoperative stage. In conclusion, ACL reconstruction using Achilles allograft can be one of effective grafts for the ACL reconstruction.

Antimony (Sb) doped ZnO thin films (0.1 at.%) were deposited on sapphire (0001) substrates at various temperatures (200 - 600$^{\circ}C$) by using pulsed laser deposition technique. All the thin films have been characterized by X-ray diffractometer, atomic force microscopy and spectrophotometer to investigate their structural, morphological and optical properties, respectively. Hall measurements were also carried out to identify the electrical properties of the thin films. These thin films were constituted in wurtzite structure with the preferential orientation of (002) diffraction plane and had as high as 80% optical transmission in the visible range. The bandgap energy also was determined by spectrophotometer which was around 3.28 eV. Hall measurements results revealed that the Sb dope ZnO thin film (0.1 at.%) grown at $500^{\circ}C$ exhibited p-type conduction with a carrier concentration of $8.633\times10^{16}\;cm^{-3}$, a mobility of $1.41\;cm^2/V{\cdot}s$ and a resistivity of $51.8\;\Omega{\cdot}cm$. We have successfully achieved p-type conduction in antimony doped ZnO thin films with low doping level even though the electrical properties are not favorable. This paper suggests the feasibility of p-type doping with large-size-mismatched dopant by using pulsed laser deposition.

목적: 상완골 간부 골절의 불유합에 대해 그 원인을 분석하고, 금속판 고정 및 자가골 이식술을 통한 수술적 치료의 결과를 평가하고자 하였다. 대상 및 방법: 총 18예를 대상으로 하였으며, 평균 추시 기간은 28개월이었다. 불유합에 대해 금속판 고정 및 자가골 이식술을 시행하였고, 골결손이 심한 경우 골단축술을 병행하였다. 술후 추시 단순 방사선 검사로 골유합을 확인하였고, ASES 점수 평가법을 이용하여 임상적 평가를 시행하였다. 결과: 불유합의 원인은 처음 수술시 금속판을 시행한 12예의 경우에서는 불충분한 금속판 길이가 6예, 금속판의 파손 2예, 나사못의 이완이나 파손이 2예, 감염이 1예, 정신과적 문제로 인한 환자의 불응성이 1예였고, 금속정 고정술을 시행한 3예에서는 전 예에서 골절 부위의 신연이 원인이었으며, 외고정을 시행한 3예에서는 불충분한 고정이 원인이었다. 전 예에서 골유합을 얻을 수 있었으며, 골유합까지의 기간은 평균 24주였다. 임상적 결과는 우수가 11예, 양호가 6예, 보통이 1예였다. 결론: 불유합에 대한 수술 시 불유합 부위에 존재하는 섬유조직이나 괴사된 골조직을 철저하게 제거한 후, 충분한 길이의 금속판 내고정술 및 자가골 이식술을 이용하면 만족스러운 결과를 얻을 수 있을 것으로 사료된다. Purpose: To evaluate the results of the compression plate fixation and autogenous bone graft in the management of humerus shaft nonunion. Materials and Methods: Eighteen cases were treated for humerus shaft nonunion using compression plate fixation and an autogenous iliac bone graft. The mean follow-up period was 28 months. Bony union was confirmed from the serial radiographs and the clinical outcomes were assessed according to ASES scoring system. Results: In 12 cases of initial plate fixation, the causes of nonunion were 6 cases of inadequate plate length, 2 with a broken plate, 2 with screw loosening, 1 infection and 1 noncompliance of a psychiatric patient. In 3 cases of initial intramedullary fixation, the cause of nonunion was a distraction of the fracture site. In 3 cases of external fixation, the cause of nonunion was inadequate fixation. All cases showed bony union after an average of 24 weeks. The clinical outcomes were 11 excellent, 6 good and 1 fair. Conclusion: In the treatment for nonunion, compression plate fixation with autogeneous bone graft after complete removal of the fibrous and necrotic tissue is believed to give satisfactory results.
