Endoscopic ultrasonography (EUS) has been developed for the diagnosis of various gastrointestinal diseases or extra-gastrointestinal diseases, and extended to interventional approach. In fields of mediastinal diseases, EUS is an effective diagnostic method for the staging of esophageal cancer, lung cancer and other mediastinal diseases. Recently, EUS guided fine needle aspiration or biopsy makes the histologic diagnosis possible in various mediastinal diseases, and would reserve many avoidable surgical cases.

Purpose: To evaluate the reoperation rate and the change of exo-angle according to compliance level of part time occlusion therapy in recurrent intermittent exotropia. Methods: This retrospective study included 52 patients of recurrent intermittent exotropia who followed up more than 5 years after their first operation. They were ordered part time occlusion therapy for recurrent exotropia. The patients were divided into 4 groups according to the level of compliance of part time occlusion therapy (\'excellent\', \'good\', \'fair\', \'poor\'). We evaluated the reoperation rate in 5 years after the first operation and the change of exo-angle from the early recurrent time according to compliance levels. Results: The reoperation rate within 5 years after the first operation of \'excellent\' and \'good\' compliance groups was lower than that of \'fair\' and \'poor\' groups (33.3, 26.3, 73.7 and 45.5% respectively) and the degree of exo-angle progression from the early recurrent time of the \'excellent\' and \'good\' compliance groups was less than that of \'fair\' and \'poor\' compliance groups, both results of which were statistically significant (p=0.02, 0.03). Conclusions: Part time occlusion therapy in recurrent intermittent exotropia has good long-term effects of decreasingreoperation rates in patients with a high level of compliance.

Purpose: To investigate the influence of preservation of an epithelial sheet in Epi-LASIK on postoperative pain and epithelial wound healing time. Methods: This prospective study included 34 eyes of 17 patients with myopia who received Epi-LASIK. An epithelial flap was created using the epikeratome (Centurion SES, Norwood Abbey EyeCare, Australia). After the stroma was ablated using the MEL 80 (Carl Zeiss Meditec. Germany) excimer laser, the epithelial sheet was replaced on the stromal bed in one randomly selected eye of each patient, and removed in the contralateral eye. The pain scores at postoperative day 0, 1, 2, 5 and the numbers of days for the complete epithelial wound healing were compared between the sheet-preserved and the sheet-removed eyes. At 1 month postoperative, uncorrected visual acuity (UCVA), refractive error and corneal haze were also compared. Results: Pain scores on the day of operation were lower in sheet-preserved group and statistically significant (p=0.01). On postoperative day 1, 2, and 5, pain scores did not reach statistical significance (p=0.24, 0.08, 0.56, respectively). The mean epithelial healing time was 4.88±0.93 days for the flap-preserved eyes and 4.29±0.77 days for the flap-removed eyes, which showed statistical significance (p=0.01). No significant difference was noted between the 2 groups for mean UCVA, corneal haze and refractive error at 1 month postoperative. Conclusions: A preserved epithelial sheet reduced early postoperative pain but did not accelerate epithelial wound-healing rate.
공공기관 정보보안수준 향상을 위한 분임담당자 중심 업무분장 개선에 관한 연구

지난 2011년부터 2015년까지 공공기관 대상 해킹시도가 총 11만 5천 건에 달하는 것으로 밝혀졌다. 이에 국정원은 지난 2012년에는 준정부기관을 대상에 포함시키는 등 현재는 최대 800여개의 국가 공공기관을 광범위하게 평가하면서 미흡한 점을 보완하도록 지시하고 있다. 하지만 여전히 한수원 해킹과 같은 정보보안 침해사고가 일어나고 있다. 한수원은 전체 인력 2만여 명 중 전산 및 보안 인력이 53명에 불과했음에도 불구하고 2013년, 2014년 내부인원 관련 거의 완벽에 가까운 점수를 받았다. 이를 통해 우수한 평가를 받는 것과 정보보안사고 발생 시 조직적으로 대응하는 것은 별개라는 것을 확인할 수 있다. 본 논문에서는 정보보안 인력 확충이라는 공감대적인 문제에서 벗어나 공공기관의 전사적인 보안수준 향상이라는 과제를 현실화하기 위한 방편으로서 주로 비 전담 분임 인력을 효과적으로 운영할 수 있는 업무분장 개선안을 제시하고자 한다. It was found to have hacking attempts totaling 115,000 to target the public sector since 2011 to 2015. National Intelligence Service was conducting survey information security management states of a wide range of national-public institutions up to 800 including government agencies in the 2012, while instructing to complement shortcomings. However, there is still going to occur invasions, such as Korea Hydro & Nuclear Power hacking. Even though KHNP's security personnel was only 53 people, in the total 20,000 workforces, got the almost perfect score in the 2013 and 2014 related to information security personnel. Through them, we can confirm that between the organizational response to information security incidents and something theoretical is very far. In this paper, we suggest solutions not using the professional staff management but the non-professional staff management to upgrade the level of public agencies information security.
