Cleaning of foreign matter and corrosion products on surface among conservation treatment of iron artifacts is an important part for looking up a original form. The sand blaster is the most popular equipment when it removes the foreign matter and corrosion products on iron artifacts surface. Current foreign matter and corrosion products equipment, which mostly uses, is sand blaster. Glass dust which sprayed from sand blaster is harmful and causing environmental pollution. In order to solve these problems, we investigated the $CO_2$ snow cleaning that use a eco-friendly equipment to apply for cleaning foreign matter and corrosion products on surface of iron artifacts. It examined by using sand blaster and $CO_2$ snow cleaning to aged steel coupon and iron artifacts. In case of aged steel coupon, the result showed that the sand blaster and $CO_2$ snow cleaning methods were similar to the degrees of cleaning foreign matter and corrosion products, through surface roughness, color measurement and SEM. $CO_2$ snow cleaning applied to aged steel coupons weren't worn out the surface in comparison with sand blaster by SEM. When applied to the iron artifacts, power nozzle of the $CO_2$ snow cleaning was an excellent cleaning effect that surface wern't worn out in comparison with sand blaster. And, it showed that internal structure change of metal was no found before and after cleaning by X-ray radiography. Consequently, we confirmed that cleaning of the sand blaster and power nozzle of $CO_2$ snow cleaning were similar to the effect. But, it's very careful to use this method because of high outlet pressure of power nozzle for applying to the iron artifacts. As a result of experiments, it could be found that the cleaning methods should be selected depending on internal state of the artifacts. 철제유물의 보존처리 과정 중 표면 이물질 제거는 유물의 원형을 찾아주는 중요한 단계이다. 현재 표면 이물질 제거 시 가장 많이 사용하는 sand blaster (air brasive)의 경우, 분사되는 유리가루는 인체에 유해하고 환경오염을 유발하는 주요한 물질이다. 그러므로 이런 문제점을 보완하기 위해 타 산업분야에서 친환경세정장비로 많이 쓰이고 있는 $CO_2$ snow cleaning을 철제유물 표면 이물질 제거에 적용하여 비교·연구 하였다. 실험은 부식시험편과 철제유물에 sand blaster와 $CO_2$ snow cleaning을 적용하여 비교 분석하였다. 부식시험편의 경우, sand blaster와 $CO_2$ snow cleaning 방법 모두 이물질 제거 정도, 표면 거칠기, 색도 측정 결과가 유사하게 나타났으며, 특히 SEM을 통해 $CO_2$ snow cleaning을 적용한 부식시험편은 sand blaster에 비해 표면을 마모시키지 않는 것을 확인하였다. 또한 철제유물에 적용한 경우, $CO_2$ snow cleaning의 power nozzle은 sand blaster에 비해 표면을 마모시키지 않고 고른 표면을 유지하는 등 세정효과가 우수하게 나타났다. 그리고 X-ray촬영을 통해 이물질 제거 전과 후 금속 내부의 구조적 변화는 없음을 관찰하였다. 결론적으로 sand blaster와 $CO_2$ snow cleaning의 power nozzle은 이물질 제거 효과가 유사함을 확인할 수 있었다. 그러나 $CO_2$ snow cleaning의 power nozzle을 철제유물에 적용하여도 sand blaster와 유사한 효과는 얻을 수 있으나, 분사압력이 높을 경우 철제 유물이 손상될 우려가 있으므로 유물 내부 상태에 따라 적용여부를 판단해야 함을 본 실험을 통하여 알 수 있었다.

With the development of the chemical industry, the chemical accident is increasing every year, thereby increasing the risk of accidents caused by chemicals. The Ministry of Environment provides the criteria for determining shelter-in-place or outdoor evacuation by material, duration of accident, and distance from the toxic substance leak. However, it is hard to say that the criteria for determining the transition point are not clear. Transition point mean the time that evacuation method is switched from shelter-in-place to outdoor evacuation. So, the purpose of this study was to calculate appropriate transition point by comparing the cumulative toxic load. Namdong-gu in Incheon Metropolitan City was finally selected as the target area, considering the current status of the population of Incheon Metropolitan City in 2016 and the statistical survey of chemicals in 2016. The target materials were HCl, HF, and NH₃. Modeling was simulated by ALOHA and performed assuming that the entire amount would be leaked for 10 min. Residents' evacuation scenarios were assumed to be shelter-in-place, immediate outdoor evacuation, and outdoor evacuation at an appropriate time after shelter-in-place. Based on the above method, the appropriate transition point from residents located in A(800 m away), B(1,200 m away), C(1,400 m away) and D(2,200 m away) was identified. In HCl, appropriate transition point was after 15 min, after 16 min, after 17 min, after 20 min in order by A, B, C and D. In HF, appropriate transition point was before 1 min or after 16 min, before 4 min or after 19 min, before 5 min or after 20 min, before 14 min or after 26 min in order by A, B, C and D. In NH₃, appropriate transition point at A was before 4 min or after 16. Others are not in chemical cloud. This study confirmed the transition point to minimize the cumulative toxic load can be obtained by quantitative method. Through this, it might be possible to select evacuation method quantitatively that cumulative toxic load are minimal. In addition, if the shelter-in-place is maintained without transition to outdoor evacuation, the cumulative toxic load will increase more than outdoor evacuation. Therefore, it was confirmed that actions to reduce the concentration of chemicals in the room were necessary, such as conducting ventilation after the chemical cloud passed through the site.

Purpose: To reveal the incidence and clinical manifestations of steroid-induced cataract, and to evaluate the visual outcome after cataract surgery in children. Methods: We reviewed the charts of the pediatric patients who had been receiving oral prednisolone for at least one year and had visited the ophthalmologic clinic between January 1991 and December 2006, and enrolled the patients who had been diagnosed as having steroid-induced cataracts. We investigated the total dose and duration of medication and compared the visual acuity (VA) at the initial visit with that of the last follow-up. We also compared the pre- and post-operative best corrected visual acuity of the patients who had undergone cataract operation. Results: Among the 1408 patients who had been treated with systemic steroids for over one year, lens opacities were found in 92 eyes (2.5%). The total duration and dose of medication were not significantly correlated with the VA (R2<0.1). The lens opacities were found bilaterally in 88 eyes (91.7%), and unilaterally in 4 eyes (8.3%). The posterior subcapsular opacities were the most frequent (84.8%). In 81 eyes who had not undergone surgery, there was no significant change of VA (p=1). The 11 eyes who had undergone cataract surgery showed significant increases in VA (p<0.01). Conclusions: The incidence of steroid-induced cataract in pediatric patients was 2.5%. The dose and duration of medication were not significantly correlated with the visual impairment. There was no significant change in VA during the follow-up. The surgical outcome of the cataract operation was favorable.

Purpose: RetisertTM (fluocinolone acetonide implant) has recently been approved for clinical use in patients with noninfectious posterior uveitis. We report a patient with intractable chronic Behcet's panuveitis who underwent RetisertTM implantation and showed a favorable outcome. Case Summary: A 30-year-old male affected with intractable Behcet's uveitis of both eyes for over one year which did not respond to oral steroids and immunosuppressants; subcutaneous interferon injection caused undesirable side effects such as impotency and pyrexia. Initial visual acuities were 20/1000 in the right eye and 20/100 in the left eye, and both eyes showed severe panuveitis with posterior subcapsular cataract, especially in the right eye. The subtenon triamcinolone injection was performed in the right eye, which was only effective to anterior uveitis, and RetisertTM was implanted in the right eye after the cataract operation. Two months later the visual acuity increased to 20/25, and the inflammation was totally controlled. There were no ocular or systemic adverse events. Conclusions: RetisertTM is a fast, effective, and safe treatment for chronic, non‐infectious posterior uveitis. J Korean Ophthalmol Soc 49(6):1007-1012, 2008

Purpose: Rice starch is known not to be suitable to Mook. Its gel is not hard and elastic enough and too sticky. This study investigated the effects of agar, carrageenan, and gelatin addition on low amylose rice flour paste and gel properties for making Mook. Methods: Angemi, low amylose rice, and Goamibyeo, intermediate amylose rice, were dry milled. The properties of Mook were determined by texture profile analysis (TPA), cold storage stability, and sensory acceptance. Results: Addition of agar and carrageenan increased cold paste viscosity, whereas addition of gelatin decreased cold paste viscosity while improving breakdown and setback viscosity. When 30% of gelling agents such as agar, carrageenan, and gelatin were added to low amylose rice, Angemi, Mook-like gels were formed. The hardness, adhesiveness, and springiness of gelling reagent-added Angemi Mook increased, whereas cohesiveness decreased, and fracturability was not observed. The addition of gelling agent decreased lightness and increased yellowness. Angemi Mook added with gelatin showed the best freeze-thaw stability while addition of agar and carrageenan increased syneresis. The carrageenan-added Angemi Mook was equal to Goamibyeo 100% Mook in all sensory acceptance properties without significant difference. Conclusion: Above results suggest that addition of carrageenan and gelatin to low amylose rice can be used to produce Mook with improved physical properties.

Purpose: As the public interest in entrepreneurship has been highlighted and entrepreneurship policies have been generated, this study is to construct Entrepreneurship Ecosystem (EE) models which have a significant relationship to national entrepreneurship with quantitative analysis. It aims to provide implications to EE policymakers that which national components are effective in cultivating innovative entrepreneurship and validate its EE quality based on quantitative performance goals. Methods: This study utilizes secondary data, categorized under the PESTLE factor from credible international organizations (WB, UNDP, GEM, GEDI, and OECD) to determine significant factors in the quality of the entrepreneurial ecosystem. This paper uses the Multiple Linear Regression (MLR) analysis to select the significant variables contributing to entrepreneurship performance. Using the AUC-ROC performance evaluation method for machine learning MLR results, this paper evaluates the performance of EE models so that it can allow approving EE quality by predicting potential performance. Results: Among nine hypothesis models, MLR analysis examines that the number of the Unicorn company, Unicorn companies' economic value, and entrepreneurship measured as GEI can be reasonable dependent variables to indicate the performance derived from EE quality. Rather than government policies and regulations, the social, finance, technology, and economic variables are significant factors of EE quality determining its performance. By having high Area Under Curve values under AUC-ROC analysis, accepted MLR models are regarded as having high prediction accuracy. Conclusion: Superior EE contributes to the outstanding Unicorn companies, and improvement in macro-environmental components can enhance EE quality.

In order to prepare high-quality activated carbons (ACs), coal tar pitch (CTP), and mixtures of CTP and petroleum pitch (PP) were activated with KOH. The ACs prepared by activation of CTP in the range of $700{\sim}1000^{\circ}C$ for 1~5 h had very porous textures with large specific surface areas of $2470{\sim}3081m^2/g$. The optimal activation conditions of CTP were determined as CTP/KOH ratio of 1:4, activation temperature of $900^{\circ}C$, and activation time of 3 h. The obtained AC showed the highest micro-pore volume, and pretty high specific surface area and meso-pore volume. The micro-pore volumes and specific areas of activated mixtures of CTP and PP were similar to each other but the meso-pore volume could be increased. In order to change the degree of crystallinity of precursors before KOH activation process, the CTPs were carbonized in the range of $500{\sim}900^{\circ}C$. As the carbonization temperature increased, the specific surface area and pore volume of the activated ACs with the same activation conditions for CTP decreased dramatically. It was demonstrated that the increased pore size distribution of AC electrodes in the range of 1 to 2 nm plays an important role in the performance of electric double-layer capacitor.
