Purpose: The purpose of this study was to evaluate the effects of an educational video program on bowel preparation for a colonoscopy. Methods: The study used a non-equivalent control group and non-synchronized design as a quasi-experimental research involving 101 participants undergoing bowel preparation for a colonoscopy (experimental group 51, control group 50 subjects) at W. university hospital, from Aug. 7 to Oct. 31, 2013. The control group received verbal education with an explanatory note while the experimental group received education using a video program. To measure knowledge of diet restrictions and compliance with ingesting bowel preparation solutions, a questionnaire, based on The Korean Society of Gastrointestinal Endoscopy's Guide (2003), developed by Sam-Sook You, was used after revisions and supplementation was done. To measure bowel cleanness, the 'Aronchick Bowel Preparation Scale' was adopted. Data were analyzed using the SPSS WIN 12.0 program. Results: A higher proportion of the experimental group showed a positive change in knowledge level on diet restrictions (U=1011.50, p =.035) and ingestion of bowel preparation solutions (U=980.50, p =.019), a higher level of compliance with diet restrictions (U=638.50, p <.001), ingesting bowel preparation solutions (U=668.00, p <.001) and the level of bowel cleanness (${\chi}^2$=17.00, p <.001) than the control group. Conclusion: The results of this study indicate that a video educational program for patients having a colonoscopy can improve knowledge, level of compliance with diet restrictions, ingestion of bowel preparation solutions, and bowel cleanness. Therefore video educational program should be used with this patient group.

Mucoepidermoid carcinoma of the lung can be divided into low grade and high grade varieties, like their major salivary glands counterparts. This carcinoma comprises only. about 0.5% of all pulmonary neoplasma. Their clinical and biologic behaviors are closely related with histologic grade of carcinoma. We have experienced two cases of mucoepidermoid carcinoma. Case 1 occurred in a 16 years old male and showed the histologic features of low grade type. This carcinoma arised from the right upper lobe bronchus which was removed by the right upper lobectomy. Case 2 occurred in a 41 year old male was the high grade carcinoma located at the distal left main bronchus which was removed by the left pnemonectomy.

Purpose: This study was a randomized single-blind trial of whole versus split-dose PEG solutions for colonoscopy preparation to compare the patient compliance, quality of bowel cleansing, and endoscopist's satisfaction. Methods: The participants were recruited from outpatients who planned to receive colonoscopy of C hospital in Busan. Sixty participants were randomly assigned to receive either a spit-dose group(n=30) consuming $2{\ell}$ of PEG solution twice, or a whole-dose group(n=30), consuming $4{\ell}$ of PEG solution once. These participants completed the questionnaire to assess their compliance before colonoscopy. The quality of bowel cleansing was assessed using the Ottawa Scale with the endoscopist who was blinded to the type of preparation, and their satisfaction by using VAS. Results: The participants who did not completely consume $4{\ell}$ of PEG solution were less in split-dose than in whole-dose group (0% vs 13.3%). The split-dose group complained less about abdominal pain(t=2.644, p=0.009) and abdominal bloating(t=2.802, p=0.013) with a statistical significance. For the quality of bowel preparation, there were no significant differences in the bowel cleansing scores and the endoscopist's satisfaction between two groups. Conclusion: Colonic preparation with split-dose of PEG solution could be a more useful method for better patient compliance, with no significant impact on bowel cleansing quality.

Objective: This study addressed the case of a cerebral infarction patient with recurring aspiration pneumonia. Methods: A patient diagnosed with cerebral infarction with recurring aspiration pneumonia was treated with Korean medicine therapies, including herbal medication (Shigyungbanha-tang-gami), acupuncture, electro-acupuncture, and moxibustion combined with antibiotics for 31 days. To evaluate the therapeutic effect, we checked chest X-rays, lab evaluations, the number of night suctions, and body temperature. Results: After treatment, chest X-rays and inflammation markers improved. In addition, the number of night suctions decreased, and the body temperature was normalized. Aspiration pneumonia recurred. However, the intensity of the symptoms gradually weakened, and the recovery speed increased. Conclusion: These results suggest that Korean medicine therapies, including Shigyungbanha-tang-gami combined with antibiotics, have a beneficial effect on recurring aspiration pneumonia, an additional disease related to cerebral infarction.

The sintering behavior of La-modified PbTiO3 ceramics was investigated in order to improve the poor sinterability of PbTiO3. Addition of La improved the sinterability. It was confirmed that this improvement was due to the decrease in tetragonality ratio c/a of crystal lattice. The variations of dielectric constant and pyroelectric coefficient were measured with temperature. It was observed that with the increase of La content, Curie temperature decreased and dielectric constant at room temperature increased. La-modified PbTiO3 ceramics had smaller pyroelectric figure of merits than those of pyroelectric materials in use. The effects of grain size on dielectric and pyroelectric properties were also investigated. The change of grain size had effect on maximum dielectric constant and pyroelectric coefficient, but is had little effect on pyroelectric figure of merit at room temperature. The closer examination near ferro-paraelectric phase transition temperature revealed that the behavior of phase transition approached a more relaxor character with the increase of La content and the decrease of grain size.

본 연구에서는 새벽과 오전에 비교적 흐렸음에도 불구하고 오존 주의보가 발령된 1999년 7월 18일을 대상으로 하여 고농도 오존의 발생에 대한 연구를 하였다. 부산 지역 3곳에서 동시에 1시간당 120ppb이상의 고농도는 11시 이후부터 15시에 걸쳐 구름이 엷어지면서 강하게 내리쬔 일사량에 의해 급격히 증가하여 생성된 것으로 나타났다. 특히 본 연구에서는 오전 9시나 10시경에 나타나는 혼합층 성장에 따른 상층의 고농도 오존의 연직혼합 현상은 없었던 것으로 보인다. 1999년 7월 18일의 고농도 오존은 공기가 정체한 상태에서 11시 이후의 강한 일사에 의한 광화학반응에 의해 1시간당 50ppb의 오존이 생성되는 고속생성에 의해 오존주의보가 발령된 것으로 판단된다. 따라서 향후 이러한 기상상태가 예상된다면 고농도 오존발생에 대한 경각심을 가지는 것이 현명하다고 본다.

Not only in Korea, but also in other countries, most helicopter accidents occur at low altitude. Analysis on accidents data collected both in Korea and other countries has brought two conclusions. Firstly, helicopter operations during the night hours carries a high risk. Secondly, the most common cause of night hour operations is loss of control due to the flight illusion. As an operation relying on a night vision in particular has a very high accident hazard, accompanying instruments such as NVG are ought to be provided. Hence, a thorough preparation and inspection on missions for night forest fire extinguishing should be required and perfect guidelines/road maps and enough training programs for the operation should be provided before the engagement in missions.

The rough growth surfaces of diamond films fabricated by the hot filament CVD were polished using thermomechanical polishing method. And then, its application to the optical windows was discussed through the measurement of transmittance in the range of infrared radiation and analysis of surfaces structure. The results were compaerd with those of the films polished with conventional mechanicla polishing. The transmittance of the mechanically polished film reached 57~66% over the whole range from 500 to 4000 cm-1. But the transmittance of the film polished with thermomechanical polishing method was reduced below 35%. This decrease in transmittance was due to both the graphitization of diamond on the polished surface and the growth of $\beta$-SiC at diamond/Si interface during polishing. The residual Fe in hte thermomechanically polished surface was confirmed by SIMS analysis. This Fe played the role of the graphitization of near surface region of the diamond film.
