In recent years, the government's urban housing expansion policy has resulted in increased construction and remodeling work of residential houses and apartments, causing more industrial accidents at elevator installation sites. Typically, accidents occur during the installation and dismantling of work scaffolds inside the hoistways or using non-standardized work scaffolds due to their structural instability. In view of this, the present study deals with the development of a standardized elevator system scaffolding that can be safely installed outside the hoistway, securing the work platform inside the hoistway. An improved version of the scaffolding system eliminates the need to enter the hoistway for the scaffolding installation, thereby preventing accidents.

Objective: The purposes of this study are to survey needs for changing accident investigation from blaming to systems approach and to briefly summarize systems-based accident analysis techniques. Background: In modern complex socio-technical systems, accidents are caused by a variety of contributing factors including human, technical, organizational, social factors, not by just a single violation or error of a specific actor, but accidents investigation used to be focused on the incorrect action of individuals. A new approach investigating causes of accidents as a symptom of a deficient system is required. Method: This study was mainly based on survey of literatures related to accidents, accidents investigation, which included academic journals, newspapers, etc. Results: This study showed that accidents investigation of Korea focusing on blaming is problematic. This was confirmed by two concepts of migration and hindsight bias frequently found in accident causation studies, and an attribute of accidents having varying causes. This was illustrated with an example of Sewol ferry capsizing accident. Representative systems-based accident analysis models including Swiss cheese model, AcciMap, HFACS, FRAM and STAMP were briefly introduced, which can be used in systematic accidents investigations. Finally, this study proposed a procedure for establishing preventive measures of accidents, which was composed of two steps: public inquiry and devising preventive measures. Conclusion: A new approach considering how safety-critical components such as technical and social elements, and their interactions lead to accidents is needed for preventing reoccurrence of similar accidents in complex socio-technical systems. Application: The results would be used as a reference or guideline when the safety relevant governmental organizations investigate accidents.

Unpaid Family Worker is blind area of industry safety. Danger of industrial accident is some high but because was excepted in industrial accident compensation insurance application. In most case, because paltry Unpaid Family Worker is no opportunity to take safety education to prevent industrial accidents and there are few safety facility and safety equipment, etc., among business, it may be said that probability to suffer industrial accidents on a trifling mistake or carelessness is higher than general worker of business. Consider such difficult actuality of Unpaid Family Worker and our country must give these benefit of industrial accident compensation insurance application, as opened the door of insurance application in recognition of worker position by "Industrial accident compensation insurance Law" to middle·smaller enterprise's business proprietor or special form labor employees.

This study aims to propose a conceptual design of information displays for supporting responsive actions under severe accidents in Nuclear Power Plants (NPPs). Severe accidents in NPPs can be defined as accident conditions that are more severe than a design basis accident and involving significant core degradation. Since the Fukushima accident in 2011, the management of severe accidents is increasing important in nuclear industry. Dealing with severe accidents involves several cognitively complex activities, such as situation assessment; accordingly, it is significant to provide human operators with appropriate knowledge support in their cognitive activities. Currently, severe accident management guidelines (SAMG) have been developed for this purpose. However, it is also inevitable to develop information displays for supporting the management of severe accidents, with which human operators can monitor, control, and diagnose the states of NPPs under severe accident situations. It has been reported that Ecological Interface Design (EID) framework can be a viable approach for developing information displays used in complex socio-technical systems such as NPPs. Considering the design principles underlying the EID, we can say that EID-based information displays can be useful for dealing with severe accidents effectively. This study developed a conceptual design of information displays to be used in severe accidents, following the stipulated design process and principles of the EID framework. We particularly attempted to develop a conceptual design to make visible the principle knowledge to be used for coping with dynamically changing situations of NPPs under severe accidents.

Even though the automation of industrial machinery has dramatically increased, most industries still require human hands for the production of goods. Our hands are essential to our existence. For this reason, hand injuries caused by industrial accidents have become an important issue lately. Most hand injuries are external wounds and constitute 38.6% of disabling industrial accidents. This significant statistic cannot be ignored by rehabilitation programs. The rate of success in operations of finger and hand injuries has increased, but relatively less consideration has been given to physical therapy, rehabilitation, research, or systematic installment in terms of welfare, which would help the injured carry on the nominal life they lived before their injury. Therefore, it is necessary to study systematically all related aspects to provide patients with physical therapy, rehabilitation, and social welfare, in order to restore their social, professional, and economical capabilities. Physical considerations, functional usability, and cosmetic restoration, as well as the patients' mental state must be addressed. The results of the study shows several problems. Medical appliances, manpower, and the environment of the treatment rooms are very poor. The patients cannot receive treatment early enough nor enough treatment because of too many patients for too few physical therapists. Close cooperation between physical therapists and doctors, nurses, or related departments is lacking. Furthermore, it is irrational that industrial accident premiums for the exert; e treatment of hand injury patients are not itemized. Lack of recognition of the importance of specialty in hand injury therapists leads to the lack of professionalization of systematic hand injury treatment In order to solve these problems, the professonalism of physical therapy should be acknowledged and particular treatment courses should be available and/or required. Based on the understanding of the hand injury patients' needs, new theories of physical therapy should be developed and modem medical appliances and facilities should be available, in order to provide the patients with qualitative medical treatment, which then will facilitate the patients' recovery.

The industrial accident rate has been steadily decreased by making all efforts for the prevention of accidents after enacting Occupational Health and Safety Act in 1981. However, ordinary typed industrial accidents still occur in small and medium sized enterprises(SME). Timely Technical Guidance(TTG) project of Korea Occupational Safety & Heath Agency(KOSHA) for SME's was initiated to visit and provide the analysis and control of industrial accidents by the staffs of KOSHA as soon as possible after accidents occurred. This study is conducted to analyze the questionnaire survey for employers, workers and TTG personnel of KOSHA with being evaluated positively whether the demonstration project of TTG has been executed consistently. However, it is suggested that the understanding of TTG project and legal support are necessary for the establishments, and the development of a variety data and lots of available contents is necessary to increase satisfaction of the TTG project. The accident rate of SME's which are employed less than 50 workers is expected to be largely decreased with applying the control and improvement over this study with maintaining and developing TTG technology.

The studies on semiconductor industrial accident in korea have been focused on the frequencies of each type of safety management employee, characteristics, cause and unsafe conditions, acts and so on. Those attributes of semiconductor industrial accidents were usually analyzed independently, so that it was hard to provides a wel-developed process and systematic guidelines for efficient safety management. Therefore, there were a few studies based on comprehensive survey in terms of the shape type of safe management. The questionnaire survey carried out for the 284 workers who were responsible for safety management in center with cooperation companies in semiconductor industry factor analysis showed that there were three factors of safety management. First, investment and operation and management for accident prevention, Second, unsafe act and condition, safety management Third, general human error and behavior. The industries of respondents were correlative with three groups. Three groups showed statistically significant differences on the number of cases. Actually, the group with the larger investment and the more unsafe cause, human error of accidents prevention had a smaller causes of accident cases.
