The aging of the population has a fundamental impact on the national economy, including decline in productive population, atrophy of available funds, slowdown of technological innovation, slowdown of economic growth, and decrease in vitality of society as a whole. Increase of elderly population would lead to increase in elderly welfare consumers, which would also lead to increase the demand for elderly welfare services. However, due to the continuation of the low birth rate, there is a great shortage of human resources who can handle this. In such a situation, the main goal of the elderly welfare system in the future should aim to actively try to design effective policies, prepare systems, and implement services for the problems of the aged society, and to find ways to expand the finances, manpower, methods, and facilities necessary for the welfare of the elderly. Elderly welfare services in Korea have been changed and developed in accordance with socioeconomic changes such as industrialization and urbanization. This study examines the changes in elderly welfare services in Korea by the flow of times and presents a method which utilizes artificial intelligence and Internet of Things in services for the elderly welfare consumers to improve both quality and efficiency.

The purpose of this study is to survey and analyze the conditions and automation of sewing machines and thereby, address the problems and their solutions to help local sewn products enhance their international competitiveness. The results of study can be summarized as follows : 1. It was found that most of the sample companies were getting smaller scale or pettier in terms of capital, number of employees or scale of factory. The interest in facility investment was relatively higher, which suggests high interest of our sewing companies in facility investment. 2. Most of the sample companies were well equipped with the essential and several auxiliary sewing machines, but poorly equipped with the special or automated sewing machines. 3. The ratio of idle machines was highest in sewing work, compared with cutting or finishing work, primarily due to decreased orders, aging machines or reduced manpower.

The results of study can be summarized as follows: 1. Few sewing companies committed their workers to a professional and systematic training course. 2. Brands as Brother, Juki, Yamato, Singer and Nara were being much used. Among them the Brother was most popular. The age of the sewing machines was between one and six years. Most companies were repairing their machines. The manual main sewing machines were more frequently out of order than other machines. The ratio of idle machines was highest in sewing work, compared with cutting or finishing work, primarily due to decreased orders, aging machines or reduced manpower. 3. Most of the sewing companies were feeling necessary for automated sewing machines.

In this paper, we introduce a new technique for automatic construction of steel frames in high-rise buildings. Basically, we combine advanced robotic technologies to building construction techniques. Four main topics will be developed such as: 1) Planning and synthesis of automatic construction system, 2) Development of construction factory system with climbing oil-pressured robot, 3) Core techniques for automatic assembly for steel frames, and 4) Intelligent resource management system. We expect that this new technique will increase the construction efficiency and will alleviate the manpower shortage problem in the aging society.

There is concern about the increased risk of accidents from manual investments due to ground handling service operators, aging equipment and manpower shortages. Therefore, it is necessary to improve the quality of ground treatment services and safety management at the airport. Therefore, this study analyzed the domestic and overseas ground operation status and the license handling procedure of aircraft handling business. In addition, a case study on the evaluation system of international organizations examined the applicability of the certification body to the Korean situation. It is practical in that it provides policy implications for improving the quality of groundwork not covered in previous studies. This is expected to improve the constitution, improve quality, improve airport operations, and operate safely.

The need for synthetic automation is increasing in preparation for a gradual decrease in laboratory research manpower due to low birth rate and aging. In this study, the existing laboratory synthesis method is analyzed based on the systems engineering technique. Then, it led to the derivation of the system requirements for a fixed-based robot manipulator capable of recognition, decision and control. The robot is equipped with replaceable modular end-effectors and designed depending on the purpose and process of the synthesis. The robot with an end-effector was implemented as PoC(Proof-of-Concept), and the functions for pipetting automation was verified.

With the aging of buildings, the number and importance of regular inspections of buildings are increasing. The current safety inspection goes through a procedure in which a skilled technician visits an old building, visually checks it, takes a photo, and finally organizes and judges it at the office. For this, field personnel and analysis and review personnel are required. Since the inspection procedure includes taking pictures, a huge amount of data has been accumulated from the time digital photos were used to the present. When a model that can check cracks outside a building is developed using these data, manpower and time required can be greatly reduced. Therefore, this study aims to create a model for classifying cracks that occur outside the building through the artificial intelligence method. The created model can be used as a basic model for determining cracks only by external photography in the future, and furthermore, it can be used as basic data for calculating the size and width of cracks.

In view of the labor-intensive characteristics of the construction industry and the persistent negative image, the problems of continuous aging and manpower shortage in the domestic construction industry are becoming more and more serious, which must be solved for the survival of the domestic construction industry. China has made certain achievements in prefabricated buildings. Through this research, we describe the development process of China's prefabricated buildings in different stages, and analyze the necessary policy promotion and standard support in the development of prefabricated buildings. Analyze and examine the necessary conditions for China's prefabricated building achievements and success factors, and make better proposals for the development of the construction industry in South Korea.

국내 건설현장의 인력은 점점 더 고령화 되고 있다. 건설기능인력의 부재 및 인력수급의 어려움으로 인한 건설공사의 생산성 및 품질저하를 막기 위한 다양한 방법들이 고안되고 있다. 특히 건설공사에 필수적인 중장비와 관련해서 Machine Guidance (MG), Remote Machine Control 등 다양한 방법을 적용하여 생산성 제고 및 품질 향상을 도모하고 있다. MG의 등장 이래로 많은 선행연구가 진행되었으나, 측설(공사 등에 있어서 굴착 경계면, 기준선 중심선 등을 표기하는 것)이 힘든 환경에서의 현장 테스트는 아직까지 부족한 상황이다. 본 연구에서는 측설이 복잡한 현장을 대상으로 MG 굴삭기의 현장 테스트를 진행하고 생산성 분석, 품질평가를 수행하였다. MG 굴삭기를 적용한 후 생산성을 분석한 결과 최솟값은 20.5%, 최댓값은 56.9%, 4일 평균 생산성은 표준품셈 대비 38.3% 증가하였다. 또한 품질평가를 진행한 결과 선행연구 결과 대비 수평 오차 ${\pm}1cm$, 수직 오차 ${\pm}2cm$로 검증되었다
