과거 건설공사의 목표는 원가절감과 공사기간의 단축을 통한 효율성 증진이었다. 하지만 최근 안전관리의 중요성이 부각되고 있으며, 고용 노동부는 산업 재해로 인한 사망자를 절반으로 감소하겠다는 목표를 설정하였으며, 이에 따라 제도적 및 법적 개선이 추구되고 있으며 안전에 대한 필요성이 강조되고 있다. 하지만 일부 대형 건설 회사를 제외한 대부분의 건설업체는 안전관리에 많은 부족함을 보이고 있다. 이러한 건설현장의 안전문제를 해결하기 위하여 본 논문에서는 스마트 안전모와 비콘을 이용하여 건설현장 안전관리 시스템을 설계 및 구현하였다.

A study is for the approach that we could reduce the logistics costs through uprising the efficiency, complying to the demand in time, stock management based on the general production plan in the point of SCM. We will take following steps to get the goal. First, we will overview the physical distribution expenses annually. Second, will find the main cause of optimal load loss by improper container and lack of delivery flexibility to the demand. Third, the goal will be inferred through the fast information share based on organic relationship, the establishment of general production plan, the improvement of stock management plan. By way of this process, it can be accomplished expense reduction as well as flexible establishment of the reduction of worker's load.

The Center for Children's Foodservice Management periodically visited children's foodservice facilities for hygiene, safety and nutrition management, and the 'HSQ (Hygiene Safety Quotient) and NQ (Nutrition Quotient) Management Web & App Program' was developed and applied to improve the health, safety, and nutrition management status of children's foodservice facilities. The HSQ is a comprehensive hygiene and safety index consisting of six categories from the hygiene and safety checklist for children's foodservice facilities provided by the Ministry of Food and Drug Safety. The NQ is a nutrition index for foodservice facilities consisting of five categories from the nutrition checklist. First, this program can be used to efficiently understand the actual conditions of children's foodservice. Foodservice facilities are provided with the result report prepared by the center without restrictions on time or place. Second, it can be used as "a channel for comfortable communication with foodservice facilities". Foodservice facilities are provided with a route where questions and resolutions can be communicated to the center. Third, it is easy to compare and review the results of foodservice facilities by institution and number of visits while downloading the results data at the same time, as the result report is written based on hygiene, safety, and nutrition visits. Through such programs, it is believed that standardized work and integrated management will improve the work efficiency of the center's employees. It is also thought that these programs will promote healthier life-styles in children by establishing a safe food environment for children's foodservice.

The weekly ultrasound scanner (US) observations of reproductive organs in a commercial dairy herd with the popular stanchion style management were conducted for over 26 months. Based on reproductive records, the following were evaluated: 1) the effect of postpartum period commencement of US monitoring on herd reproductive efficacy, and 2) the effectiveness of a US monitoring-based diagnosis and subsequent treatments of reproductive disorders on postpartum reproductive efficiency. The reproductive parameters of cows, which were subjected to US monitoring between Days 30-40 (Day 0 = day of parturition), Days 41-50, Days 51-60, and above Day 61, were compared. The reproductive parameters of cows diagnosed as having reproductive disorders (RD) with US monitoring before or after the first artificial insemination (AI) were also compared. It was found that the day of commencement of US monitoring in cows diagnosed with and without RD significantly affected the period towards the first AI and the open period. In particular, cystic follicles and anoestrus detected either before or after the first AI significantly affected herd reproductive efficiency. The implementation of US monitoring improved reproductive efficiency by reducing the open period and increasing the number of milking cows in the herd. The results of this field trial indicate that the postpartum reproductive management of dairy cows with the use of the US monitoring system is one strategy to improve reproductive efficiency, especially in a high-yielding dairy herd reared stanchion management style.

Safety-related systems (SRSs) has widely used in shipbuilding and power generation to prevent fatal accidents and to protect life and property. Thus, SRS performance is a high priority. The safety integrity level (SIL) is the relative performance level of an SRS with regard to its ability to operate reliably in a safe manner. In this article, we proposed an optimal design procedure to achieve the targeted SIL of SRSs. In addition, a more efficient failure mode and effects diagnostic analysis (FMEDA) process and optimization model were developed to improve cost efficiency. Based on previous IEC 61508 diagnostic analyses that revealed unnecessary costs associated with excessive reliability, the new approach consists of two phases: (i) SIL evaluation by FMEDA, and (ii) solution optimization for achieving the target SIL with minimal cost using integer-programming models. The proposed procedure meets the required safety level and minimizes system costs. A case study involving a gas-detection SRS was conducted to demonstrate the effectiveness of the new procedure.

This study uses Pathfinder software to simulate and analyze the safe evacuation of university dormitory occupants. Fire safety issues in densely populated dormitory buildings are gaining increasing attention, and improving emergency evacuation efficiency is crucial for reducing the harm caused by fire incidents. The study focuses on a student dormitory building in a university, simulating different evacuation scenarios and analyzing the impact of factors such as evacuation routes, personnel distribution, exit width, and stair width on evacuation time. Based on the actual dormitory conditions, parameters such as gender ratio, height range, shoulder width, and walking speed of the occupants were set, and evacuation times in various scenarios were compared.The simulation results show that proper planning of evacuation routes and increasing stair width significantly reduced evacuation times. The study recommends that universities establish systematic emergency response plans, conduct regular evacuation drills, optimize student dormitory layouts, and consider increasing stair width in dormitory building designs to improve evacuation efficiency and safety.

In the information society where knowledge plays a significant role, the value of the corporate organization creates knowledge strategically and spreads it to the whole organization so as to reinforce the efficiency of the work force. After KMS(Knowledge Management System) was recognized as one of core competences of company, KMS based on information technology has been introduced actively to many corporate organizations for the implementation of realizing knowledge management. As the strategic use of KMS increases in company, it has attracted attention to the system and the investment in the system, now attention has brought to the effect of the system. The efficiency and effectiveness of KMS has been tackled as one of the most important issues, and then many studies have been implemented to measure the result of the system. The purpose of this study is to overcome these problems and to help make an important decision in establishing introduction strategy by abstracting the reasons and success factors and result indices which are important sources for introducing KMS.
