Purpose: To evaluate the effects of intrastromal air injection and intrastromal balanced salt solution (BSS) injection on corneal keratocyte apoptosis. Methods: Twelve right eyes of New Zealand White rabbits were divided into an air-injected group (n=6) and a hydro-injected group (n=6). Contralateral eyes served as a control. Air or Balanced salt solution (BSS?, Alcon, USA) was injected into the deep corneal stroma at the paracentral area to propagate into nearly the entire cornea. To reduce the intraocular pressure, anterior chamber paracentesis was performed. The animals were sacrificed 4 hours (n=6) and 24 hours (n=6) after surgery. Central cornea buttons were retrieved to stain with Hematoxylin & Eosin and TUNEL (Apoptag?, Chemicon). The mean number of apoptotic keratocytes was counted in 24.67±4.04 consecutive high power field (HPF). Results: The mean number of TUNEL-positive cells at 4 hours was 12.85±7.25/HPF and 0.25±0.44/HPF in air-injected and hydro-injected eyes, respectively. It was reduced to 6.25±4.02/HPF and 0.15±0.37/HPF in air-injected and hydro-injected eyes after 24 hours. The air-injected group showed significantly more TUNEL-positive cells compared with the hydro-injected or control group until 24 hours (p=0.001, p=0.001, Mann-Whitney U test). Conclusions: Intrastromal air injection induces significant apoptosis of keratocytes suggesting some damages in the peripheral cornea when used in deep lamellar keratoplasty.

Emergency numbers, such as 112 and 119, are used in many countries to connect people in need with emergency services such as police, fire, and medical assistance. We describe development directions of intelligent response technology for emergency calls. The development of this technology refers to enhancing the efficiency and effectiveness of response systems by using advanced methods such as artificial intelligence, machine learning, and big data analytics. We focus on a system that assists the receptionist of an emergency call. In the future, the recognition rate and decision-making accuracy of intelligent response technologies should be improved considering characteristics of public safety and emergency domain data. Although the current technology remains at the level of assisting a receptionist, a fully autonomous response technology is expected to emerge in the future.

이민정,최지웅,김현맥,안광국,Lee, Min-Jung,Choi, Ji-Woong,Kim, Hyun-Mac,An, Kwang-Guk 한국하천호수학회 2009 생태와 환경 Vol.42 No.3

본 연구에서는 대전광역시를 관통하는 도심하천인 대전천의 4개 지점을 선정하여, 2004년 8월에서 2007년 10월까지 총 8차례에 걸쳐 생물학적 건강도 평가 및 물리적 서식지 평가를 실시하였고, 환경부 수질측정 망 지점자료를 이용하여 화학적 수질특성을 분석하였다. 물리적 서식지 평가 지수(QUEI)는 평균 78.2(범위: 47$\sim$124)로 "보통상태"(Fair)로 나타났다. QUEI 값은 최상류지점(S1)에서 최대치(112, "양호상태")를 보인 반면, S3에서 SS(보통$\sim$악화상태)로 가장 불량한 서식지 상태를 보였는데, 이는 심각한 하상구조의 교란, 하상도로 및 인위적활동에 의한 것으로 사료되었다. 화학적 수질변수들은 하류로 갈수록 점차 악화되는 것으로 나타나 하천주변 도심으로부터 유입되는 유기물 오염에 의한 것으로 사료되었다. 또한 TP 및 전기전도도(Conductivity)는 집중강우로 인한 희석효과가 뚜렷이 나타난 계절적 변이가 큰 것으로 나타났다. 본 연구에서는 총 5과 24종 6909개체의 어류가 채집되었고, 피라미(Zacco platypus)가 81.6%로 우점하는 것으로 나타났다. 다변수 어류 평가모델인 생물통합지수(IBI)는 평균 17(범위: 12$\sim$30)"보통상태"(C)로 나타났으며, 하류지점으로 갈수록 생태건강성이 악화되는 양상(S4: 14, "불량상태")을 보였다. 따라서 대전광역시 도심의 상가밀집지역 및 주거지역을 관통하면서 생활하수 유입 및 각종 오염원에 의한 심각한 수질저하 현상에 의한 것으로 사료되었다. We evaluated stream health, based on integrative approaches of qualitative habitat evaluation index (QHEI), chemical water quality and the index of biological integrity (IBI) using fish assemblages in Daejeon Stream during August 2004 - October 2007. The QHEI values in this study averaged 78.2 (n=28, range: 47$\sim$124), indicating "fair" condition based on the criteria of US EPA (1993). The highest value was in the headwater site (S1) that was 112 (good), whereas the value in S3, mid and downstream was SS (fair-poor) that was the lowest owing to a disturbance on the bed and an artificial bank. Concentrations of chemical parameters such as BOD, TP and conductivity increased from the upstream to the downstream due to higher inputs of organic matters and nutrients from the urban area. Conductivity and TP showed a dilution of stream water by rainwater during summer monsoon. Analysis of fish compositions showed that total number of species was 24 and Zacco platypus was predominated (82%). The mean IBI was 17 (range: 12$\sim$30) during four years and the IBI values also decreased from S1 to S4. These results indicated that ecological health was degradated distinctly as the stream goes down through the city-center. We concluded that Daejeon Stream running through the city are influenced by chemical impact such as an influx of domestic sewage as well as the quality of habitat.

Background: Presently, a multidisciplinary team of doctors, pharmacists, nurses, and dietitians provides patient education to impart information on chemotherapy. However, studies on multidisciplinary education satisfaction are inadequate. In this study, we aimed to contribute to the improvement of quality of multidisciplinary education counseling for patients with cancer by developing a satisfaction questionnaire and analyzing the satisfaction survey. Methods: A questionnaire was developed by an expert group, and the responses were recorded using the 5-point Likert scale. After conducting a pre-test, factor analysis was performed to evaluate validity. The reliability of the questionnaire was measured by Cronbach's alpha coefficient. A satisfaction survey was conducted by self-administration method. Results: Based on the results of factor analysis, factors can be divided into two parts: "overall education" and "each team member's education" (total 14 questions). The construct validity and reliability of the questionnaire are sufficiently high. Fifty-one patients took the survey between January 2, 2018 and January 20, 2018. Twenty-six (51%) patients responded that they were "very satisfied" and 22 (43.1%) patients responded that they were "satisfied". Conclusion: By developing a questionnaire on multidisciplinary education counseling for patients with cancer, it is possible to perform evaluation and research of cancer patient education. This study will contribute to the management and improvement of quality of multidisciplinary education.

Objectives : The study was designed to find out the relationships between rhinitis, quality of sleep, growth among children with chronic rhinitis. Methods : This research was performed in 50 children from November 2007 to May 2008. We measured height, weight, body mass index of those children and asked to answer to the questionnaires that consist of nasal symptoms, period of time with rhinitis, sleep symptoms, parent's height, present illness, and medical history. We also analyzed correlations with this factors obtained from questionnaires. Results : 1. In 50 subjects, there were significant correlations between nasal obstruction, the quality of sleep, and the between quality of sleep and growth. But, there were not significant correlations between nasal symptoms and growth. 2. In 24 preschool children, frequency of waking up during sleeping and the number of snorers were higher and quality of sleeping was worse than those in the children who were attending school. And there were significant correlations between quality of sleep and nasal obstruction. An average of RH-MPH(Recent Height-Mid-Parental Height) is $-7.74{\pm}36.51(%)$ which means they aren't as tall as MPH(Mid-Parental Height). 3. In 26 school children, there were significant correlations between symptoms and period of rhinitis, quality of sleep and growth. Conclusions : Children with chronic rhinitis have low quality of sleep and low growth. But more studies are needed.

Purpose: To report a case of isolated cilioretinal artery occlusion associated with pseudoexfoliation syndrome. Methods: A 66-year-old female presented with acute vision loss of the right eye. Three months prior, she had been diagnosed as having pseudoexfoliation glaucoma of both eyes, and the intraocular pressure of both eyes had been well-controlled with topical medication. Results: The presenting visual acuity in her right eye was 20/100. Fundus examinations showed sectoral retinal whitening on superior macula. Fluorescein angiography revealed delayed filling of the cilioretinal artery, consistent with cilioretinal artery occlusion. No significant findings were identified by carotid doppler examination or echocardiography. After 8 weeks, retinal changes were completely resolved with improvement of her right vision to 20/25. Conclusions: Isolated cilioretinal artery occlusion may develop as an intraocular manifestation of pseudoexfoliation syndrome.

Introduction This study is the first to report a significant improvement of Soyangin patients with persistent night sweats through herbal medicine treatment. Methods We reviewed the total of 6 Soyangin patients with moderate to severe persistent night sweats who visited the outpatient clinic. The patients received herbal medicine treatment alone for 4 to 9 weeks. We evaluated the treatment outcome using Night Sweats Degree criteria, developed by Lea and Aber(1985), every other 2 to 4 weeks. In addition, we recorded the treatment period from the first visit to symptom alleviation. Results Persistent night sweats improved significantly in all 6 Soyangin patients, and 4 out of 6 patients had better sleep quality after the treatment. It took 1 to 3 weeks until the symptom alleviated from moderate or severe to mild, and 3 to 7 weeks until the patients have no sign of night sweating. The progression of persistent night sweats and treatment period until no sign of symptom varied according to the Soyangin External and Internal disease diagnosis. Discussion The Soyangin patients having persistent night sweats treated with herbal medicines showed a significant improvement in their symptoms. This result proposes the possibility of using herbal medicine in primary care patients experiencing persistent night sweats.
