우리나라 건축문화재의 Universal Design 현황과 개선방안에 관한 연구
김종혁,신병욱,이웅구 한국농촌건축학회 2020 농촌건축 : 한국농촌건축학회논문집 Vol.22 No.4
In Korea, the Basic Act is guaranteed through the “Act on the Guarantee of Convenience Promotion for Disabled Persons, the Elderly, Pregnant Women, etc.” and various ordinances. In order to improve this situation, it is necessary to introduce Universal Design (UD). By applying this where it is most needed, access to cultural properties is enhanced to promote multiple rights. Currently, the region with the largest population of the elderly in Korea is Gyeonggi-do, but the region with the highest proportion of the elderly is Jeolla-do. However, the Jeolla-do area is lagging behind in the revision of UD regulations or guidelines. Taking this into consideration and introducing it to each facility will also help to achieve balanced national development. In order to establish and apply effective universal design-related policies, it is necessary to diagnose the aspects of social change that affect our lives. In this study, the need for UD should be expanded as a basis for expanding social activities of socially disadvantaged people in Jeollabuk-do. Its goal is to diagnose the current status of UD and to suggest directions for application of improvements.

저자 등은 1996년 1월부터 1997년 12월까지 복강경하 자궁근종절제술을 시행 받은 10명의 환자를 대상으로 임상 결과를 분석하고 문헌 고찰을 하였다. 본 연구에서는 다른 복강경하 자궁근종절제술에 관한 연구에 비하여 수술시의 출혈이 많았으며, 이는 근종 주변의 자궁근에 혈관수축제를 사용하지 않은 것과 지혈에 비효율적인 단극성 전류를 주로 사용한 것에 기인한다고 분석하였다. 결론적으로 적절히 환자를 선택하고 양극성 전기 소작기를 구비한 상태에서 숙련된 복강경 시술자가 수술 원칙을 준수할 때만 효과적인 복강경하 근종절제술이 이루어 질 것으로 사료되며 수술중 및 수술후 출혈, 유착의 발생 및 향후 가임력의 향상 등에 관하여는 계속적인 연구가 요망된다고 하겠다. Traditionally, the myomectomy has been performed via laparotomy and there have been some reports that laparoscopic myomectomy has advantages of reduced intra-and postoperative morbidity, shorter hospital stay and recovery time, earlier return to normal activities, fewer postoperative adhesions and better cosmetic scars as compared with traditional abdominal myomectomy. However, the disadvantages of the laparoscopic myomectomy include increased operating time, inability to palpate the uterus during operation, and the requirement of advanced technical skills. Actually the role of laparoscopic myomectomy remains controversial until now. We experienced 33 cases of laparoscopic myomectomy from January 1996 to December 1997, but most of them were performed ancillarily during other operations for ovarian tumors, pelvic endometriosis, tubal pregnancies, etc. Among 33 patients, ten received laparoscopic myomectomy as a major procedure. We present clinical characteristics of these patients and laparoscopic procedures we performed. The average age of patients was 36.0±7.0 (mean±S.D.) years and the mean parity was 1.3 (±1.2). The myomas were subserosal type in 5 cases, intramural type in 4 cases and intraligamentary type in one. The maximal diameter of the myomas ranged from 1.5 to 7.5 cm and the mean diameter was 5.2 (±1.6) cm. Seven cases had only one myoma, but 3 cases had two or more. The operation time ranged from 65 to 200 minutes (mean: 121.5±46.4) and average hemoglobin change(preoperative- postoperative hemoglobin) was 2.5 (±1.2) g/dl. There was no intraoperative and postoperative complication except one case of trocar site hemorrhage. In conclusion, the laparoscopic procedure is effective for myomectomy, but it is essential to adhere to the basic surgical principles to optimize its safety and efficacy. However, its advantages are still needed to be established based on long term outcomes.

LPG BLEVE 피해분석 및 안전거리 설정에 관한 연구
김종혁,이병우,김정욱,정승호 한국안전학회 2020 한국안전학회지 Vol.35 No.6
Boiling Liquid Expanding Vapor Explosion(BLEVE) can cause not only economic damage to the plant but also serious casualties. LPG accidents account for 89.6 percent of all accidents caused by gas leaks in Korea over the past nine years, while casualties from accidents also account for 73 percent of all accidents, according to statistics from the Korea Gas Safety Corporation. In addition, a potential explosion and a fire accident from one LPG storage tank may affect the nearby storage tanks, causing secondary and tertiary damage (domino effect). The safety distance standards for LPG used by LPG workplaces, charging stations, and homes in Korea have become stricter following the explosion of LPG charging stations in Bucheon. The safety distance regulation is divided into regulations based on the distance damage and the risk including frequency. This study suggests two approaches to optimizing the safety distance based on the just consequence and risk including frequencies. Using the Phast 7.2 Risk Assessment software by DNV GL, the explosion overpressure and heat radiation were derived according to the distance caused by BLEVE in the worst-case scenario, and accident and damage probability were derived by considering the probit function and domino effect. In addition, the safety distance between LPG tanks or LPG charging stations was derived to minimize damage effects by utilizing these measures.

General purpose of cylindrical capacitive displacement sensor(CCS) is measuring run-out motion and deflection of rotor. If CCS has narrow sensing range, its sensitivity coefficients must be calibrated precisely. And x, y component of CCS output can be coupled. In this research, CCS calibration procedure is automated with automatic calibration program and PC-controlled stage. And, coupled-terms of CCS signals were removed and the errors between measured position and mapped CCS signal were reduced obviously by sensitivity matrix that linearly
