Purpose: We report a case of orbital abscess secondary to acute dacryocystitis in which the patient had been cared for chronic dacryocystitis. Methods: A 59-year-old woman presented to our clinic with a history of chronic sinusitis from childhood and right chronic dacryocystitis treated for 6 years. She had sufferred from influenza 2 weeks previously and complained of painful lid swelling, limitation of ocular movement, exophthalmos, chemosis, and decreased vision of the right eye for 2 weeks. An orbital CT scan was taken and bacterial culture and sensitivity tests were done from the discharge. Results: CT scan showed inflammation and abscess formation around the right nasolacrimal duct orifice which was swollen and widened. Some of the inflammation tissues extended into the retrobulbar portion. Streptococcus pyogenous was cultured. Lid swelling, pain, exophthalmos, and visual acuity improved after external dacryocystorhinostomy, and surgical drainage. Conclusions: We should be careful in a case of acute dacryocystitis underlying chronic dacryocystitis as it easily causes complications, and in such a case early surgical management as well as antibiotics therapy is more effective.

Purpose: To compare the decentration and tilt between Acrysof? Single-piece and Acrysof? Multipiece posterior chamber intraocular lenses (PCLs). Methods: The subjects of this study comprised 14 patients (15 eyes) using an Acrysof? Single-piece and 14 patients (15 eyes) using an Acrysof? Multipiece. All of these PCLs were inserted into the capsular bag after continuous curvilinear capsulorhexis and phacoemulsification. The decentration and tilt of the Acrysof? Single-piece and the Acrysof? Multipiece were measured on the 1st, 30th and 60th postoperative day using an anterior eye segment analysis system (EAS-1000, Nidek, Japan). Results: There was no statistically significant difference in decentration between the Acrysof? Single-piece and the Acrysof? Multipiece PCL on the 1st (P=0.254), 30th (P=0.078), or 60th (P=0.520) postoperative day. Also, there was no statistically significant difference in tilt between the two PCLs on the 1st (P=0.165), 30th (P=0.395), or 60th (P=0.419) postoperative day. Conclusions: Although the decentration and tilt of the Acrysof? Single-piece and the Acrysof? Multipiece PCL showed no significant difference after 60 postoperative days, inappropriate insertion into the capsular bag may necessitate more long-term study and follow-up with numerous cases.

The aim of this article concentrates on an action plan designed for newly-incoming international/-cultural residents in campus housing in Colorado State University (CSU) in the States. This action plan is needed not only for international/-cultural resident’s imminent needs to become an approved resident but for both housing staff and school authorities to better understand what the new residents’ common difficulties and how to help them in communication; thus, it can pave an avenue to influence policy making to keep sustainability in intercultural community. The action plan is specified mainly into two parts. The first part is survival English classes, and the second one is for both understanding on cultural differences along with adaptation and intercultural awareness. From the two carefully-designed parts, the present study finds that those newly-coming international/ -cultural residents enter actively into the process of getting themselves be empowered as an internationally/-culturally approved resident in the university campus housing.

대중사회를 이끌던 일방향적 의사소통은 21세기가 되면서 쌍방향적인 의사소통으로 바뀌었다. 이러한 소통의 확대를 잘 반영하고 있는 것이 ‘SNS’이다. 디지털 기기에 친숙한 청소년들에게 SNS를 이용한 학습방법의 가능성을 탐색하는 것은 의미 있는 일이다. 본 연구에서는 SNS를 활용한 사회과 블렌디드 수업모형을 개발하고, 이를 시사토론 동아리에 적용하여 모형의 보완사항을 점검하고 수정하였다. 또한 개발된 모형의 효과를 분석하여 블렌디드 러닝 모형의 장점과 한계를 제시하였다. SNS를 활용해 학생 및 교사가 소통을 확대하고 서로간의 피드백을 증가시킨다면 교실 안에서 국한된 수업이 아니라, 다양한 정보를 교환할 수 있는 온라인 공간을 마련하여 수업 효과를 극대화 할 수 있을 것이다. 이를 위해서는 교사의 수업 부담을 줄일 수 있는 효율적인 모형 개발, 비판적 사고력 이외의 수업에 미치는 효과에 관한 연구가 이어질 필요가 있다. This study focused on developing a blended learning model for social studies using SNS by applying it to a current affairs debate club, checking the drawbacks of the model and modifying them. The following steps were set in order to analyze the effect of the developed model. The Blended-Learning Model was developed to step 5 of the ADDIE model. After the class applying the developed model, this model was evaluated for improvement. Therefore, the modified model has 8 steps. ① Selecting the discussion topics ② Choosing a topic for the group ③ Guiding the discussion ④ Preparing the discussion and collecting the data ⑤ Announcing and discussing the results ⑥ Instructing ⑦ Evaluating ⑧ Feedback and reflections. In the flood of information, there was increased importance placed on critical thinking skills to find the necessary information and make a proper decision. Developing the abilities to assess the information through rational judgment is essential in the social studies cultivating civic competency. To conclude, the blended learning using SNS can help cultivate teachers to teach students using current technology.

In the case of medical facilities, the evacuation time is delayed due to the decrease in the number of people in the hallway and exits due to the increase in the width of evacuation by using mobile beds, wheelchairs, crutches, etc. Accordingly, it is considered to secure evacuation capacity to reduce evacuation time according to corridor width and exit width. Accordingly, we would like to compare the standards related to the evacuation capacity of medical facilities in Korea and NFPA, derive differences, and use evacuation simulations to compare evacuation times according to changes in corridor width and exit width. In Korea, it is calculated based on the floor area by use, but in the case of NFPA 101, the number of evacuation routes, stair width, corridor exit width, and two-way door width was stipulated depending on the number of people. Using evacuation simulation, efficient evacuation capacity is calculated according to the reduction of evacuation time by changing the width of the hallway, changing the width of the exit, the width of the corridor, and the width of the exit. The evacuation simulation is intended to be used to secure evacuation safety of domestic medical facilities by calculating the effective evacuation time reduction by changing the width of the hallway and exit.

최근 의료시설은 밀양세종병원 화재(2018), 김포요양병원 화재(2019), 윤호21병원 화재(2020) 등 다수의 사상자가 발생한 화재가 지속적으로 발생하고 있다. 의료시설의 재실자는 일반시설에 비해 피난능력이 저하되는 특징이 있다. 이는 자력피난이 불가능하거나 일반인에 비해 피난능력이 저하된 재실자가 24시간 상주하고 있어 화재 시 피난대응이 늦어지며, 피난소요시간도 증가되는 문제점이 있다. 의료시설의 피난안전성 확보를 위해 화재사례 조사를 통해 국내 의료시설의 피난상 문제점을 도출하며, 건축법의 피난안전 기준과 국외 기준을 비교함으로써 기준의 차이점을 도출하고자 한다. 또한 국내외 피난기준, 재실자의 조건 등을 활용하여 피난시 뮬레이선을 통해 피난소요시간을 분석하여 적정한 출구폭, 복도 넓이를 검토하고자 한다. 국내외 피난안전 기준을 조사한 결과 국내의 의료시설 복도 폭 1.8m 이상이며 막다른 복도에 대한 규정은 없고1), 문 폭의 규정은 통과 유효 폭 0.9m이상 전면 유효거리 1.2m 이상으로 규정한다2). NFPA101 의료시설 기준 복도 폭 2.44m 이상, 막다른 복도 9.1m, 입원실에서 복도 출구 폭 112cm, 수평피난구 서로 반대방향으로 열리는 양개형 문 폭 각 105.5cm 이상 규정하고 있다3). 피난시뮬레이션(Pathfinder)을 활용하여 국내외 피난기준에 재실자의 보행특성 및 조건(목발, 휠체어 등) 변수를 적용하여 피난소요시간을 분석하고자 한다.

In previous studies, fire simulation was used to estimate the fire spread path. According to previous studies, the fire spread path was estimated to be the main staircase, but consideration of interior materials and internal bulkheads was insufficient. In this study, the ignition time of the 3rd layer was analyzed using the prediction formula considering the interior materials and internal bulkheads. As a result of referring to the architectural drawings, it was found that the interior material of the 3rd floor was made of polystyrene. The internal ignition time of the third floor using FDTs was calculated to be 14,070 seconds (about 234 minutes). The internal ignition time of the 3rd floor using the Handbook on Design Calculation Methods of Fire Behavior was calculated to be 3,104 seconds (about 51 minutes). As a result of calculating the ignition time through the predictive formula, there is a large difference in the ignition time, so it is necessary to review the condition of the variable as a result of the calculation in the future.
