It is an important issue in cost management to contract with the standard of cost estimate by the reasonable way in public construction projects. For the standard of cost estimate based on the Standard Estimating System, there is a difference of labor inputs between Standard Estimating System and actual quantities in construction projects. The duration of form work in multi-family housing depends on the manpower compared with other work, which is the critical path on the schedule management to be decided quality, and is the important to the cost management of construction projects. This study presented a simulation model of the productivity analysis for selecting the standard work type of form work in Multi-family housing construction projects.

The purpose of this paper is to analyze the productivity of the costal fisheries in Jeonnam Province. In this study, the operational characteristics and Cobb-Douglas production function of coastal fisheries were examined based on a research on the actual condition of costal fisheries (RACF). The statistical analysis of RACF data reveals that Cobb-Douglas production function consists of the three variables: fishing quantity per ton-age, the number of fisherman per ton-age and fishing equipment cost per ton-age. The results of this study show us that the relation and productivity between labor and capital of the operational equipment in the coastal fisheries. If extensive comparable biological and market data become available, analysis model can be widely applied to yield more accurate results.

For labor-intensive sewing industry, productivity could be enhanced with the proper utilization of standard time system. This paper develops a standard data for sewing operations through three stages. The first is to identify the manual motions from sewing operations. The second is to simplify the MTM-1 data considering the frequency and the nature of basic motions occuring in the operations. Finally we synthesize the standard data using the simplified MTM-1 by the film analysis of the actual operations pictured in the field. The standard data developed is shown to be easier and faster with reasonable accuracy in determining the standard time compared to the MTM-1.

There are insufficient models that find problems and solutions for accident prevention through risk assessment and suggest safe work process and work instruction from foundation works to finish work for accident decrease. This paper presents a quantitative risk assessment model by analysis of risk factors in each process such as foundation, erection, pier, pier upper and etc based on accident examples and investigation on actual condition in bridges construction work. In addition, the safety management system was developed to perform risk assessment of construction and use it for effective safety training for labor.

The technical expert standing system of our construction industry is operated by the Ministry of Labor subjective national technical qualification law, as the professional engineer, architect and architect-engineer and so on. The construction management(CM) which is introduced on middle 1990 activates a building industry the condition of the essential indispensability for is becoming, is not officially recognized with is judged as the nostril people for qualification of the civil CM educational institutions ha the certification which is a each educational program and a separate way and it is the actual condition which is become accomplished, In this research, it observes the capital increase reserve problem point which is a domestic CM and the certification integration which is a report and system anger it leads and with national certified qualification it develops to present the improvement program for, it does to sleep.

There are insufficient models that find problems and solutions for accident prevention through risk assessment and suggest safe work process and work instruction from foundation works to finish work for accident decrease. This paper presents a quantitative risk assessment model by analysis of risk factors in each process such as appurtenant works, temporary works, structural works, equipment work, finishing work and etc based on accident examples and investigation on actual condition in plants construction work. In addition, the safety management system was developed to perform risk assessment of plants construction and use it for effective safety training for labor.

Security control using surveillance cameras is established when people observe all surveillance videos directly. However, this task is labor-intensive and it is difficult to detect all abnormal situations. In this paper, we propose a deep neural network model, called AT-Net, that automatically detects abnormal situations in the surveillance video, and introduces an automatic video surveillance system developed based on this network model. In particular, AT-Net alleviates the ambiguity of existing abnormal situation detection methods by mapping features representing relationships between people and objects in surveillance video to the new tensor structure based on sparse coding. Through experiments on actual surveillance videos, AT-Net achieved an F1-score of about 89%, and improved abnormal situation detection performance by more than 25% compared to existing methods.

Modern society unanimously recognizes the importance of education for the constructive socio-economic development of the global economy and adopts humanistic principles for building social interaction both at the state and interstate levels. The study aims at analyzing the main directions of transforming the system of higher engineering education with due regard to the actual needs of the labor market caused by the digitalization of the economy, as well as changes in the content and methodology of implementing the main socially significant processes that ensure the vital activities of modern society.

In construction sites, small-scale construction quantities or limited work hours below the daily work volume may occur due to on-site conditions. For small-scale quantities, the input of equipment and labor is designed based on an hourly basis in the invoice, resulting in a difference from the actual cost. In this study, we aim to explore solutions from the perspective of construction cost standards to secure appropriate construction costs for small-scale and time-limited construction sites. Firstly, to preserve the basic construction costs on-site, we established standards where half the cost would be charged for construction quantities below four hours and a full day's cost would be designed for construction quantities between four to eight hours. Additionally, realistic construction cost calculation standards are expected to be provided by realizing a surcharge rate for work hour limitations to secure appropriate construction costs.

산업화 이후 여성, 특히 기혼여성의 경제활동 참가율이 급격히 증가하고 있다. 따라서 본 연구에서는 기혼여성의 고용지위 결정 시에 고려되어야할 변수들에 대해서 분석할 필요가 있을 것으로 판단된다. 이에 기혼여성의 고용지위를 결정하는 변수들을 개인관련변수, 자녀관련 변수, 가구관련변수, 취업관련변수 등으로 구분하여 연구모형을 설정하였다. 이를 근거로 기혼여성의 고용지위를 결정하는 변수들에 대해서 다항로짓회귀분석을 실시하여 다음과 같은 결과를 도출하였다. 첫째, 개인특성변수에 대한 분석결과, 기혼여성은 도심에 거주할수록 그리고 학력이 높을수록 임금근로의 고용지위를 갖는 것으로 나타났다. 둘째, 자녀관련 변수에 대한 분석결과, 자녀의 수가 많으며, 6세 미만의 자녀가 존재하지 않을 경우 임금근로의 고용지위를 갖는 것으로 나타났다. 셋째, 가구관련특성 변수에 대한 분석결과, 가족이 핵가족일수록 그리고 가족 구성원 중 소득원 수가 적을수록 비임금근로의 형태를 갖는 것으로 나타났다. 마지막으로 취업관련 변수에 대한 분석결과에서는 여성이 혼전에 취업을 하였을 경우와 남편이 취업을 하지 않은 경우, 그리고 남편의 직종이 비전문직일 경우에 임금근로의 고용지위를 갖는 것으로 나타났다. 이상의 결과 분석을 통해 기혼여성의 고용지위 결정에 영향을 미치는 요인이 차이를 보임으로써 기혼여성의 고용지위 향상을 위해서는 다음과 같은 방안을 제시하고자 한다. 첫째, 기혼여성의 경우 어린 자녀가 있을 경우 고용지위가 낮게 나타나 기본적으로 결혼 및 출산으로 인한 가사 및 자녀양육 부담이 기혼여성의 지속적인 취업을 방해하는 요인으로 작용할 수 있어 이에 대한 문제해결 방안이 요구된다. 이를 위해서는 선진국의 경우에서와 같이 가사 및 자녀양육과 경제활동을 병행할 수 있는 탄력적인 근무시간제도 활성화가 필요하겠다. 그러나 이러한 탄력근무제도 활성화는 관련된 보호법 제정 등 제도적인 보호가 따라야만 실효를 거둘 수 있을 것이다. 둘째, 가사와 경제활동을 조화롭게 병행할 수 있는 제도로 가장 대표적으로 논의 되는 제도가 육아휴직제도이다. 현재 육아휴직제도가 법제화되어 있기는 하지만 그 활용도가 매우 저조한 실정이다.
