본 연구는 간호대학생의 윤리적 가치관이 환자안전에 대한 태도에 미치는 영향을 규명하고자 시도된 서술적 조사연구이다. 연구대상자는 S지역 2개 대학의 간호학 전공 4학년 학생 179명이며, 2017년 8월 21일부터 9월 15일까지 설문조사 하였고. 수집된 자료는 SPSS 24.0 Version을 이용하여 분석 하였다. 연구결과 연구대상자의 환자안전에 대한 태도 수준은 3.74점으로 중간단계였다. 윤리적 가치관의 대상자관계영역과 간호업무영역, 협동자관계영역은 환자안전에 대한 태도와 양의 상관, 인간생명영역은 음의 상관이 있는 것으로 나타났다. 환자안전에 대한 태도에 유의하게 영향을 미치고 있는 변수는 일반적 특성의 학업성적, 전공만족이며 윤리적 가치관의 하위영역인 대상자관계영역, 인간생명영역, 간호업무영역이었고 이들 변수의 설명력은 38.6% 이었다. 이러한 결과가 간호대학생의 교육 정책 개발 시 고려되어야하며 추후 효과 검증을 위한 연구가 요구된다.

To prevent safety hazards in dangerous working area, we have proposed an intelligent image analysis system. Six common patterns of safety violations of workers' are defined and its motion detection algorithms are developed for alarm to CCTV monitoring system. Developed algorithms are implemented at 195 dangerous areas such as chemical and gas treated room. The results of violated motion detection ratio by developed system shows 94.95% of true positive cases, and 0.21% of false positive cases from all 587,645 event cases in one month implementation period. In the period, it is observed that the number of safety rule violations and the following accidents are decreased.

In the case of office buildings, domestic and Chinese evacuation laws were compared regarding the evacuation of horizontal and vertical buildings and evacuation to refuge safety areas. A simulation was conducted based on a refuge safety area in China. In the case of evacuating 1 floor, there was no significant difference in the flow of occupants to an ancillary room area in a domestic or Chinese building, but in China, the corridor width was narrower and the occupants have saw a long. In the case of evacuating 15 floors, the flow of occupants to an ancillary room area was different. In the case of China, it was possible for occupants to enter the ancillary room more quickly because the ancillary room area was wider than those found in domestic buildings, allowing quickly passage the ancillary room door. The results of this study found that if corridor width and ancillary room area were wider, evacuation times could be reduced.

This study area show the complicated geological figure and some developed small fault area in southern of Korea. Because of insufficient investigation and design for the big slope, even the safety analysis by the specific institution, in the event, there were 6 times failure and 6 time safety analysis. After all, The height and remedial work cost of the slope became much bigger then early stage.

In general, Reinforced Slopes by Shotcrete are difficult to inspect because of stiff Slope and highly Working Area. So the Inspection Techniques are needed by the Non-contact and Non-destructive. On this Study, Appling the safety method to finding the weak zones(cavity area, dampness area, etc.) by using the Infrared Thermal Technique That is detecting the Detail Thermal Difference on the Surface of Reinforced Slopes by Shotcrete.

Recently buildings are being constructed on the downtown area. In most building construction sites on the downtown area, the need for adequate material inventories are critical in order to avoid project delays and cost increases due to inappropriate deliveries of key materials. However immoderate material inventories cause increasing inventory cost. Therefore, we need a proper management material inventories. This research re-establishes the existing safety stock and analyzes relationship between safety stock and service level. It suggests an economical re-order point based on safety stock considering service level, various demand and delivery time.

The purpose of this study was to evaluate the safety of the small reservoir, which is distributed in a rural area, based on systemic reliability. It has been estimated that safety of respective reservoir the calculation of failure probability for individual reservoirs can evaluate the safety of the reservoir of the study area. The change of safety for watershed could be figured out as that result. Probability of failure was increased from $3.90{\times}10^{-5}$ to $1.35{\times}10^{-4}$ in Naesu-inpyung reservoir, from $1.33{\times}10^{-5}$ to $4.77{\times}10^{-5}$ in Buyeon reservoir and from $4.24{\times}10^{-5}$ to $2.55{\times}10^{-2}$ in Dalakmal respectively. From the results, the collapse of the upper stream reservoir was analyzed qualitatively that may affect the safety of the reservoir on the downstream area.

The Purpose of this research was to assess food safety knowledge and perceptions on hygiene education among new owners of restaurant in Gyeongnam area. In the questionnaire survey to 462 new owners of the necessity of hygiene education, more than half of them(56.3%) answered ‘Needed’ while ‘So so(29.2%)’ and ‘No need(14.1%)’ were also not a few. For the questionnaire asked what educational area was most beneficial, ‘Restaurant management and service(53%)’ was the most selected followed by ‘Food safety management and briefing on relevant food safety regulations(20.1%)’, ‘Tax management(12.8%)’ and ‘Food culture and menu development(11.7%)’. According to evaluation on new owners’ food safety knowledge, total average score was turned out to 6.83(out of total score of 15), less than 50% of average correct answers, it signified the demand for quantitative and qualitative improvement on hygiene education. To view the three areas’ evaluation score, characteristics of foodborne illness(2.56 points, out of total 5 points) and general hygiene management(2.54 points) marked more than 50% of correct answers while critical control points marked only 1.73 points, the lowest score.

Hazardous area classification is designed to prevent chemical plant explosions in advance. Generally, the duration of the explosive atmosphere is used for zone type classification. Herein, IEC code, a quantitative zone type classification methodology, was used to achieve Zone 2 NE, which indicates a practical non-explosion condition. This study analyzed the operating pressure of a vessel handling propane to achieve Zone 2 NE by applying the IEC code via MATLAB. The resulting zone type and hazardous area grades were compared with the results from other design standards, namely API and EI codes. According to the IEC code, the operating pressure of vessels handling propane should be between 101325-116560.59 Pa. In contrast, the zone type classification criteria used by API and EI codes are abstract. Therefore, since these codes could interpret excessively explosive atmospheres, care is required while using them for hazardous area classification design.

Recently, the scale and form of the construction promoting in government and private organization have large scaled town. The underground area of whole town are used for every facilities, and most of concrete area are used for greening part for friendly environment construction. This greening part for concrete area have good point such as being amendment and various economical effect and improvement for environmental problem, moreover, the amount of greening part become great increased. For this factor, we have to newly consider to keep durable safety for concrete structure, therefore, we suggest that how to keep structural safety of greening area on the concrete.
