  • Stakeholders of a construction project expect cost savings through fast and accurate cost analysis by performing BIM-based quantity take-off (BQT). However, authors have observed that there can be discrepancies in the results of BQT depending on the level of development (LOD) and modeling methods. In addition, since quantity take-off methods are different depending on the construction work items, the combination of LOD, modeling methods of BIM, features of construction work items can cause serious overestimate or underestimate in BQT results. It is necessary to identify what kind of problems can happen and how those problems can be avoided in various construction work items, since the discrepancy of quantity take-off results has great impact on not only cost analysis but also the determination of contract amount and it can cause claims, poor construction quality, cost overruns, and many others later in the construction project. Therefore, this paper focuses the identification of issues and problems of BQT at each construction work item level based on two categorizations of structural works and interior works.

  • The populations of major cities in Australia are increasing rapidly and facing an acute housing shortage. Traditional apartment procurement techniques involve lengthy lead-times and factory-based, or offsite manufactured (OSM) multi-storey apartment buildings may offer the opportunity to help fulfill the need by significantly reducing build times. Other advantages of OSM may include superior quality, low weight ratios, economies of scale achieved through repetition of prefabricated units, use on infill sites, sustainable design standards and better occupational health and safety. There are also positive labour and training implications, which may help to alleviate an industry-wide shortage of skills through use of semi-skilled labour. Previous uncertainties about the adoption of offsite due to the high capital costs and perception issues were generally based on pre-cast concrete structures, which are quite a different building type in terms of flexibility, construction, delivery and finishes. Identification of drivers and constraints assists in the determination of current industry status, allows for a benchmark to be established and future opportunities and directions for OSM to be determined.

  • Microorganisms play an important role in the geochemical cycles, industry, environmental cleanup, and biotechnology among other fields. Given the high microbial diversity, identification of the microorganism is essential in understanding and managing the processes. One of the most popular and powerful method for microbial identification is comparative 16S rRNA gene analysis. Due to the highly conserved nature of this essential gene, sequencing and later comparison of it against known rRNA databases can provide assignment of the bacteria into the taxonomy, and the identity of its closest relatives. Isolation and sequencing of 16S rRNA genes directly from natural environments (either from DNA or RNA) can also be used to study the structure of the whole microbial community. Nowadays, novel sequencing technologies with massive outputs are giving researchers worldwide the chance to study the microbial world with a depth that was previously too expensive to achieve. In this article we describe commonly used research approaches for the study of individual microorganisms and microbial communities using the tools provided by Ribosomal Database Project website.

  • This paper deals with an intelligent digital ship which aims at development to support economic and safe services through an integration into the hierarchically layered digital signals such as ship's navigation, maneuvering and control signal and establishing a one-man bridge system in order to provide a support systems between ship and land station. This paper introduces the results of the mid-term project sponsored from Ministry of Commerce, Industry and Energy which consists of three sub-project such as INS(Intelligent Navigation System), AIS(Automatic Identification System), and IMIT (Integrated Maritime Information Technology). The INS system that can allow ships to navigate economically and safely through the integration and analysis of national data within the ship. AIS is a system that reports automatically on the location of the ship in order to prevent the collision between ships and between the ship and the land. IMIT is a integrated system for providing an efficient and economic support system between ships and the land and a ship-land platform and technologies.

  • In clinical dentistry, botulinum toxin is generally used to treat the square jaw, bruxism, and temporomandibular joint diseases. Recently, this procedure has been expanded and applied for cosmetic purposes, and it is becoming a key task to be aware of the precise anatomical structure of the target muscles to be cautious during treatment and how to prevent side effects. Therefore, the purpose of this study is to observe the anatomical structure of the superficial layer of masseter muscle and to provide a most effective botulinum toxin injection method through clinical anatomical consideration. It was observed that the muscle belly of superficial part of the superficial layer was originated from the deep to the aponeurosis of masseter muscle and descend, then changed gradually into the tendon structure attaching to the inferior border of the mandible. In this study, we named this structure deep inferior tendon. This structure was observed in all specimens. We conclude that the use of superficial layer and deep layer injection should be considered to prevent paradoxical masseteric bulging in consideration of the deep inferior tendon of superficial part of superficial layer of masseter muscle.

  • 해양경찰은 바다라는 극한 환경에서 임무수행 중 빈번히 사망 실종의 위험에 맞닥뜨린다. 사고 발생 시 신속한 신원확인을 위해 해양경찰연구센터는 해양경찰을 대상으로 DNA를 이용한 신원확인 시스템을 구축하였으며 사체가 발견되지 않을 경우를 대비해 국립묘지 안장이 가능한 장치 또한 마련하였다. 순직 실종 등 대비 신원확인용 인체유래물 보관사업 운영규칙에 따라 인체유래물의 관리, 보관, 폐기, 품질검사가 진행되며 이는 관리위원회의 감시 하에 행해진다. 한반도 해역에서는 매년 700여건의 해양 변사자가 발생하는데 사체가 늦게 발견되어 부패가 심하거나, 일부분만 발견되어 지문 또는 치아로 개인 식별이 불가능할 경우 해양 변사자의 신원확인을 위한 방법이 필요하다. 해양경찰연구센터가 운영중인 '인체유래물 보관사업'을 해양 수산 종사자, 관련 연구자, 해양 레저인에게까지 확대 실행한다면 해양 변사자 신원확인에 큰 도움이 될 것이다.

  • Consultant and owner play a very important role in the construction sector which is one of the main sectors in economic development. There are many stakeholders in a construction project including but not limited to: owner, consultant, contractor, subcontractor, and supplier. The consultant is the party who is to stay in close touch with the project owner, which both consultant and owner are considered as the main key stakeholders to make the project happen. It's not a simple task for a consultant to just implement the same style of management and control within various projects that are of a different background and character of owners. Thus, the adjusting plan management and control to the owner environment has been an essential technique to drive the project to success. The objective of this paper is to identify the significant management techniques for adjusting a plan of management and control to the owner environment in Thailand. The methodology is the identification throughout the analogous to abduction from literature review and our empirical observations of Future Engineering Consultants Co, Ltd. We have been in consultation for twenty-five years (25) in Thailand with 209 projects from both public and private owners. As a result, there are (1) Project management styles, (2) Personal style, (3) Owner expectation management, (4) Scope Management, (5) Time Management, (6) Cost Management, (7) Quality Management, and (8) Environmental Management. The input are: a clear defined goal, showing respect by giving good service, maintaining high quality, keeping in touch with owners, and resources. This would give the output of the project's success by meeting the owner's expectation and requirements.
