Herpes simplex virus(HSV) infections of the CNS are associated with significant morbidity and mortality even when appropriate antiviral therapy is administered. HSV infections of the brain can be subdivided into two categories : neonatal HSV infections, which usually are caused by HSV type 2, and herpes simplex encephalitis(HSE), which occur in patients over 3 months old and is nearly uniformly caused by HSV type 1. The clinical presentation of HSE is one of the focal encephalopathic process associated with altered levels of consciousness, fever, focal seizures and hemiparesis. But because of the lack of pathognomic clinical presentation and diagnostic procedure, the efforts to develop alternative diagnostic procedure have led to the use of new diagnostic technique such as polymerase chain reaction(PCR). We report a case of HSV type 1 encephalitis in 13 month old male infant who presented with altered level of consciousness, fever and focal seizures. With the use of the PCR, HSV-1 DNA was detected in cerebrospinal fluid from the patient. The symptoms and signs of encephalitis subsided by treatment with acyclovir in 14 days.

Purpose: Clinical manifestations and surgical outcomes of intermittent exotropia with or without dissociated vertical deviation (DVD) were evaluated. Methods: Patients who were diagnosed with intermittent exotropia following surgical correction were divided into 2 groups: 66 patients with DVD (DVD group) and 81 patients without DVD (XT group). The postoperative deviation between exodeviation of 10 prism diopters (PD) and esotropia of 5 PD was considered surgically successful. Results: The onset of strabismus occurred at an earlier age in the DVD group. There were more cases of nystagmus, inferior oblique muscle overaction, superior oblique muscle overaction, and AV pattern in the DVD group than in the XT group, but there were no differences between the 2 groups in terms of head tilt, amblyopia, and age at first operation. While exodeviation in the DVD group was smaller than in the XT group, stereopsis in the DVD group was statistically worse than in the XT group in the Titmus test. At postoperative 1 month, the XT group had better surgical outcome, but at postoperative 6 and 12 months, there were no differences in the surgical outcomes of intermittent exotropia between the 2 groups. Regarding DVD surgery, a postoperative DVD angle less than 10 PD accounted for 90.0% of the cases. Conclusions: Intermittent exotropia combined with DVD had worse stereoacuity and lesser exodeviation. There was no statistically significant difference in the surgical outcomes of intermittent exotropia with or without DVD. J Korean Ophthalmol Soc 2012;53(8):1131-1137

Purpose: To estimate the baseline demographic/ocular characteristics and associated findings of patients with foveal hypoplasia. Methods: The medical records of 42 patients (84 eyes) who were clinically diagnosed with foveal hypoplasia were retrospectively reviewed. Results: There were 28 males and 14 females with mode age at diagnosis of 1 (range, 0-60 years) year and a mean follow- up period of 9.7 ± 5.4 years. At the first office visit, the most common complaints were ocular oscillation and face turn. There were 75 eyes (91.5%) with best corrected visual acuity worse than 0.3 at the first visit, but that number decreased to 55 eyes (67.1%) at the last follow-up (age range, 7-60 years). The absolute spherical equivalent of refractive errors was 2.89 ± 2.96 diopters (D), and 71 eyes had astigmatism with a mean astigmatism of 2.1 ± 1.1 D. Forty-two patients had associated diseases: 15 (35.7%) with aniridia, 16 (38.1%) with ocular albinism and 11 (26.2%) with oculocutaneous albinism. In addition, strabismus was found in 24 patients (57.1%). Conclusions: Diseases associated with foveal hypoplasia include aniridia, ocular albinism and oculocutaneous albinism. Since foveal hypoplasia is often associated with high refractive errors and poor vision, an early prescription of eyeglasses is mandatory for management of refractive amblyopia to ensure the development of the best corrected visual acuity.

The public-private cooperation in package deal has been studied for the overseas energy resources acquisition. The effectiveness of the package deal has not been successful because the deal has led by the government organizations. It is difficult for the plant EPC companies to join the packaged deal due to the lack of the whole responsibility organization to support the participation of the package deal. The followings are suggested as the ways to strengthen of the public-private cooperation in this study. 1) the relevant public enterprise privatization 2) establishment of the joint model for leading the plant EPC companies to the package deal 3) establishment of the whole responsibility organization for the public-private cooperation.

Purpose: To evaluate the effect of the amount of cylindrical correction on the accuracy of geometric corneal centeradjusted ablation centration selected by the surgeon in advanced surface ablation-photorefractive keratectomy (ASA-PRK). Methods: Ninety-five myopic eyes of 62 patients who underwent ASA-PRK were divided into three groups based on the amount of myopic cylindrical correction: Group 1 <-0.50 D, 22 eyes; Group 2 ≥-0.50 D and <-1.00 D, 45 eyes; Group 3 ≥ -1.00 D, 28 eyes. The distances and distribution of the ablation centers from the entrance pupil center were analyzed by corneal topography at one month after ASA-PRK. Risk factors for decentration (>0.3 mm) were determined from patient-related factors such as gender, age, laterality, central corneal thickness, and order of procedure and surgery-related factors such as amount of spherical correction, ablation depth, vertical scale bar percentage, and learning effect of surgeon. Results: Mean decentration was 0.26 ± 0.15 mm (0.04 to 0.83 mm). There was no statistically significant difference in the amount of decentration among the three groups (p = 0.879). Superior-nasal displacement (53.7%) of the ablation center most frequently occurred after ASA-PRK. The amount of decentration among the three groups was not dependent on either patient-related or surgery-related factors. Conclusions: ASA-PRK using the surgeon-selected ablation center with adjustment toward the geometric corneal center was found to be highly accurate in ablation centration and did not influence the amount of ablation decentration regardless of the amount of myopic cylindrical correction.

야간에는 주간에 비해 통행량감소에 따른 운전자의 법규위반이 많아지고 음주 및 운전자의 피로가 증가하여 교통사 고의 위험성은 급격히 증대된다. 따라서 야간에 발생하는 교통사고를 줄이기 위해서는 야간의 특수성을 고려한 실효성 있는 교통사고 방지대책이 수립되어야 한다. 야간에 보행자 교통사고가 잦은 지점에 LED안전유도블록을 설치하여 도로조명개선 효과를 분석하였다. 횡단보도진입 로인 보행자대기구간에 보행선 개념으로 업라이트조명방식인 LED안전유도블록을 설치하여 효과를 분석한 결과, LED를 설 치한 지점에서 야간 교통사고 발생건수는 26.2% 부상자수는 21.2% 그리고 사망자 수는 38.3%감소하였다. 본 연구는 안전보행조명장치의 설치시기가 서로 다르며 그 표본의 수가 적어 전국적인 대표성을 가지고 있다고 볼 수는 없으 나, 체계적인 분석을 통한 개선사업의 효과를 구체화 할 수 있는 대안은 제시할 수 있을 것이다. The objective of this study was to analyze the effects of LED safety block using the government database. To evaluate these effects, the night accident data was obtained from 2007 to 2011 from the database. At the LED-installed area, compared to the uninstalled area, the number of night traffic accidents, injured and mortality had decreased by 26.2%, 21.2% and 38.3%, respectively. The LED-installed intersections are safer than the LED-uninstalled roads from a traffic accidents perspective. In conclusion, a LED safety block is quite effective in decreasing the number of traffic accidents. Although this study was conducted using the data from Changwon city, where LED safety blocks have been installed so far, these results can provide valuable data to other cities considering the implementation of these LED safety blocks.

함정 전투체계 운용성 향상을 위한 다기능콘솔 전시기 구성 및 HCI 설계

박대영(Dae-Young Park),정동한(Dong-Han Jung),양문석(Moon-Seok Yang) 한국컴퓨터정보학회 2019 韓國컴퓨터情報學會論文誌 Vol.24 No.12

함정 전투체계에는 레이더 장비, 수중센서 장비, 함포 및 미사일 제어용 무장통제 장비들과 같이 체계를 운용하기 위해 필요한 여러 장비들과 이를 통제하기 위한 다기능콘솔이 구성되어 있다. 다기능 콘솔에는 장비들의 상태정보 전시 및 장비들을 통제하기 위한 HCI 기반의 소프트웨어가 탑재되어 있고, 운용자는 탑재된 소프트웨어를 활용하여 함정 전투체계를 운용한다. 하지만 함정 전투체계를 장시간 운용함에 있어 다기능콘솔 전시기의 구조로 인한 신체적 불편함, 다양하고 복잡한 HCI 구성으로 인한 운용자의 피로도 증가 등 문제점들이 발생하고 있다. 이러한 문제점들은 함정 전투체계 운용성을 저하시키는 중요한 요인이 된다. 이를 해결하기 위해, 본 논문에서는 함정 전투체계 개발자들을 대상으로 한 설문조사를 바탕으로 신체적 불편함을 줄일 수 있는 다기능콘솔 전시기 구조 설계와 운용자의 피로도를 줄일 수 있는 직관적인 HCI 설계 방안을 제안한다. 이로 인해, 향후 함정 전투체계 운용자들에게 편의성을 제공하여 기존 함정 전투체계보다 운용성을 향상 시킬 수 있는 장점을 가진다. The Naval Combat System has several equipment needed to operate the system, such as radar equipment, underwater sensor equipment, guns and missile control and armed control equipment, and a multi function console is configured to control it. The multi function console is equipped with HCI(Human Computer Interaction)-based software for displaying the status information of equipment and controlling equipment, and the operator uses the installed software to operate the Naval Combat System. However, when operating a Naval Combat System for a long time, there are problems such as physical discomfort caused by the structure of the multi function console display and increase in fatigue of the person who operates various and complicated user interface configuration. These issues are important factors in reducing Naval Combat System operability. In order to solve these issues, in this paper, based on a questionnaire survey conducted for Naval Combat System development personnel, multi function console screen design to reduce physical discomfort and HCI design to reduce fatigue and increase intuition are proposed. The proposed design is expected to provide convenience to future Naval Combat System operators and improve operation over existing Naval Combat System.
