To prevent incident of demolition work the Building Management Act was implemented to manage demolition work. According to this law, buildings with the scale upper than 500㎡ of floor area are classified as permission to conduct the demolition work, however it may be hard to perform safety management at demolition work. In addition, the risk level of demolition work is varied with related to the structure type. So, the purpose of this study is to suggest the improvements of criteria on demolition work considering building structure types including small-scale structures such as masonry, wooden, and other structure. The research process was conducted by three steps. (I) Application of Building Management Act; (II) Analysis of demolition work by structure types; and (III) Subdivision of permission targets by building structure types. The result of this study, permission ratio was only 10% for total demolition work and 2.43% for masonry. Because the masonry, wooden, and other structure types are concentrated on a floor area of small-scale, the separate criteria of demolition work is need to prevent the accident and fatal incident. Through the results, the decision maker can be utilized (1) For the special building structure types, the criteria of enhanced safety management are applied by referring to the overseas law ; and (2) The demolition work can be considered by the criteria of separate permission in terms of structure types.

This study reviews a family-friendly system of companies from the viewpoint of family resource management. The concept of a family-friendly system in the workplace means that the strategy 'supports the family' or 'is sensitive to the family life' and recognizes a need for balance between work and family. The suggestions proposed in this study were as follows: First, the direction of a family-friendly system must reflect the needs of the family members positively and recognize diversity. Second, it must consider efficient methods relating to the matter of the gender because a corporate culture enabling men to use childcare leave has not grown, even in family companies. Third, the directions to check the present developing process of our society and to develop the suitable way to each company must be shown. This study has proposed that the subjects must solve immediately in the future with understanding the contents and looking around the status of the enforcement at the inside and outside of the country for a family-friendly system to handle the balance between work and family in the workplace. The problems were the context of the introductions and the results of balancing between work and family no matter whether the introduction of the system by company or not.

Recently, overseas plant orders of domestic enterprises are steadily increased, and the amount of orders in the first half of 2014 were 93% increased compared to the previous year. In addition, now which is the third quarter of 2015, overseas plant orders are already over 249.8 billion dollars so the interests of plant industry research has been increased. In the life cycle of the plant project, CM before the construction stage is to complement the uncertainties that are inherent in the early stages of the project, and from the viewpoint of supporting the rational decision-making, the importance of its role is on the rise. Among them, excavating and investing participation plan in the planning stage is an important work that has a large impact force to influence the success and failure of future project. However, the work has become a problem with frequent consultations due to decision-making, continuous modification, and inefficient repetitive tasks. Therefore, it is needed that work process should be changed to effectively accommodate. The purpose of this paper is to derive the major work items for excavating and investing participation plan in the planning stage of the plant project, and establish a standardized work process through the Delphi analysis. The result of this study is expected to be utilized for EPC companies in ensuring the technical competitiveness in planning on overseas markets, and improve the efficiency of work.

This study explores whether the implementation of sustainability disclosure can trigger or stimulate the change in the roles of management accountants in adopting organizations in Vietnam as business partners. To do so, it explores the roles of management accountants in integrated reporting (IR) adopting organizations and sustainability reporting (SR) adopting organizations based on the use of the pragmatic constructivism (PC) theoretical framework. In addition, qualitative semi-structured interviews were used to provide an in-depth investigation of management accountants' work in both IR and SR adopting organizations. The empirical findings suggest that the adoption of the IR framework has triggered changes in management accountant roles toward the new business partner roles to support the decision-making process within their organizations. On the other hand, management accountants from SR adopting organizations still work as traditional "bean-counter" roles. Our paper concludes by indicating several propositions based on our empirical findings that can be tested by future researchers from the domain by collecting relevant data. Our study can be seen as a response to the recent call for a more in-depth examination of the practice of sustainability disclosure from the practitioners' perspectives in adopting organizations.

The present work represents a technical guideline for decommissioning a disused teletherapy machine model Theratron-780 and contains category one ⁶⁰Co radioactive source. The first section predicts the dose rate from the source in case of normal and radiological emergency situations via FLUKA-MC simulation code. Moreover, the dose assessment for the occupational during the whole process is calculated and compared to the measured values. A suggested cordoned area for safety and security in a radiological emergency is simulated. The second section lists the whole process's technical procedures, including (preview, dismantle, securing, transport and storage) of the disused teletherapy machine. Results show that the maximum obtained accumulated dose for occupational were found to be 24.5 ± 4.9 μSv in the dismantle and securing process in addition to 3.5 ± 1.8 μSv during loading on the transport vehicle and unloading at the storage facility. It was found that the measured accumulated dose for workers is in good agreement with the estimated one by uncertainty not exceeding 5% in normal operating conditions.

Looking at current construction costs estimations of publicly declared public works, there are many instances where estimation criteria are ambiguous and doesn't imply the reality. Up to date, estimation criteria for calculating construction cost estimations are simply by unit area multiplication and stochastic construction cost estimation. However, possibility of making errors are high due to using uniform data that excludes each public work's specifications and environmental conditions. Further, on the aspect of cost management, there is certain limitation in the efficiency of cost management in order-placing stage and commencing-work stage; while efficient cost management and reduction of expenses are highly possible during initial stages of the project. In this respect, the paper adopts positive approach with regards to construction cost estimations of public works and draws common elements from calculation tables of the construction cost estimations from 3 completed domestic construction works; after which, the paper analyzes whether business exposition, construction guide and publicly-declared estimated construction costs that the orderer issued are calculated economically and properly; deducing problems in the process, the paper seeks to recommend rational calculation method on this.
