Surface replication is playing an important role in the assessment of creep damage and remaining life of high temperature components. As the replication procedures, however, have not been standardized in domestic industry, its standardization is proposed in this study. For this purpose, the 2.25Cr-IMo steel was heat treated(5 min at 1,300 0C and oil quenched) to produce a simulated HAZ microstructure, and crept in air at 575 0C and under 120 MPa to produce artificial cavities. Then, the effect of surface preparation procedures on the quality of replicas was investigated using this sample. As a result, it was demonstrated that the presence of cavities may be observed readily or missed depending on the surface preparation procedures followed. Therefore it is essential to repeat three polishing/etching cycles at least in order to reveal cavitation damage accurately, even though it may be tedious or time-consuming.

Purpose: To report two cases of lacrimal drainage obstruction associated with the anticancer drug S-1 (tegafur, gimeracil, oteracil ; TS-1Ⓡ, Taiho Pharmaceutical, Japan). Case summary: (Case 1) A 34-year-old male who had previously undergone a total gastrectomy for treatment of gastric cancer visited with epiphora in both eyes that had developed 6 months after S-1 treatment. On examination, a right canalicular obstruction and left punctal and nasolacrimal partial obstruction were noted. Endoscopic dacrycystorhinostomy with lacrimal trephinization was done in the right eye and punctoplasty with punctal membrane removal and silicone tube intubation were performed in the left eye and the epiphora were successfully treated. (Case 2) A 60-year-old male who was treated with S-1 for gastric cancer presented with tearing in both eyes that had developed 2 months after S-1 treatment. Ophthalmic examinations revealed a right nasolacrimal partial obstruction in the right eye and lacrimal sac obstruction in the left. Silicone intubations were performed on both sides and the epiphora were successfully treated. Conclusions: Lacrimal drainage obstructions may develop after S-1 treatment. Therefore, ophthalmologic evaluations should be performed in patients treated with S-1 to detect lacrimal drainage obstruction. J Korean Ophthalmol Soc 2010;51(6):890-894

Purpose: To evaluate histopathologic properties of eyelid skin and conjunctiva and the association between clinical manifestation and histopathologic findings. Methods: A prospective study was conducted on the histologic findings of the upper eyelid skin and conjunctiva performed from November 2009 to February 2010 in 27 patients for upper eyelid blepharoplasty procedures. Histopathologic studies were performed for specimens collected from the upper eyelid skin and inferotemporal bulbar conjunctiva. Preoperative photographs of the upper eyelid and conjunctiva were taken to grade clinical severity of dermatochalasis and conjunctivochalasis. Results: Decrease of collagen density and elastic degeneration in the eyelid skin and conjunctiva were significantly associated with aging (p < 0.001, p = 0.001, p = 0.001, p < 0.001). Clinical severity of dermatochalasis was correlated with a decrease of collagen density and elastic degeneration in the eyelid skin, and clinical severity of conjunctivochalasis was associated with a decrease of collagen density, elastic degeneration and lymphangiectasia in conjunctiva (p < 0.001). Conclusions: Change of collagen fiber and elastic fiber in the eyelid skin and conjunctiva was observed with aging. Relaxation of the eyelid skin and conjunctiva was correlated with histologic findings. J Korean Ophthalmol Soc 2011;52(5):582-588

Purpose: To evaluate factors affecting the outcome of silicone tube intubation in patients with nasolacrimal duct obstruction. Methods: A retrospective study of the outcome of silicone tube intubation performed from August 2001 to August 2009 in 98 patients (132 eyes) with nasolacrimal duct obstruction was conducted. Improvement was defined as the disappearance of epiphora after silicone tube intubation and success was defined as maintenance of improvement by the time of the final patient follow-up. Recurrence was also defined as appearance of epiphora after silicone tube extubation. Results: The success rate was 76.5% (101 eyes), failure rate was 8.3% (11 eyes), and recurrence rate was 15.2% (20 eyes). Preoperative canaliculus irrigation test was significantly correlated with symptomatic improvement and recurrence after silicone tube intubation (p = 0.003 and 0.045, respectively). The mean time that patients experienced recurrence was 43.7 months after silicone tube intubation, according to Kaplan-Meier survival analysis. Conclusions: Preoperative canaliculus irrigation test is a simple and effective tool to estimate the outcome of silicone tube intubation. This outcome should be considered in the stage of planning treatment in nasolacrimal duct obstruction patients. J Korean Ophthalmol Soc 2011;52(2):129-135

Objectives : This study was conducted to evaluate the effects of the personal stereo system on the hearing in adolescents. Methods : A total of 68 adolescents(age: 13-18 years) who visited the ENT Department at a University Hospital in Daegu were personally interviewed. The questionnaires were about general characteristics of the subjects, the time of personal stereo system use (year, hour) and place. Cumulative exposure to the personal stereo system was calculated by the product of the total years and the daily hours of their use. Pure tone audiometry was performed and the hearing threshold was measured at 500, 1000, 2000, 4000 and 8000 Hz. Results : The average time of using a personal stereo system a day was about 3 hours and 75% of the subjects used a personal stereo system for 2-5 years. The elevation of threshold was more prominent in the subjects who used personal stereo systems for 4 years and more compared with those subjects who used them for 3 years and under. The elevation of hearing threshold was also more prominent in the subjects who used personal stereo systems for 4 hours and more a day compared with those subjects who used personal stereo systems for 3 hours and under a day. The elevation of hearing threshold was more prominent in the subjects who used personal stereo systems for 13 hour. years and more compared to the subjects who used them 12 hour. years and under. Conclusions : These results suggest that the elevation of hearing threshold can happen to adolescents who used personal stereo systems for a long time. In order to prevent hearing loss, we need to teach adolescents appropriate usage of the personal stereo system and hearing tests should be included in the periodic school-based physical examination for the adolescents.

Objective : Korean National Health and Nutrition Examination Survey is periodically conducted to produce national health indicators among Korean people. However, little is known about health indicators among military people. The authors surveyed health related behaviors in the Marine Corps enlisted trainees and tried to figure out health status indicators among them. Method : The study subjects were the Marine Corps recruits who were enlisted from July, 2008 to March, 2009 for basic military training. We surveyed the trainees with structured questionnaires including health related behaviors. We analyzed the health behavior of the subjects and the relationship between each behavior. Results : Mean age of total study subjects was 19.6 years old and smokers were 43.6% and drinkers were 98.8%. Mean BMI was 22.6 kg/m2 and Obesity prevalence was 17.1%. Smoking was related with family member’s smoking(P<0.05). According to AUDIT classification “suspicious alcohol abuse or dependency” was 29.4%. Mean AUDIT of non-smoker was 9.2 and was lower than ex-smoker, intermittent smoker and daily smoker(P< 0.05). Difference of BMI according to the smoking status was not statistically significant(P >0.05). Conclusion : In the Marine Corps recruits, alcohol drinking seems to be a most serious health problem and health education and research for alcohol drinking needs to be done.
