  • The Swedish Fire Research Board was established in 1979 to initiate and fund relevant fire research efforts. The Board is responsible for a long term research programme revised every third year, and the Board is one of two major Swedish sponsors of all fire research. Beside the Board we also have the Swedish National Rescue Services, funded by the government. BRANDFORSK gives very high priority for the industry and the insurance company and the need they express for fire research. Research that the Rescue Services Board are funding is mainly focusing the need for the fire department. The Swedish Fire Research Board, BRANDFORSK, is the joint agency of the Swedish government, the insurance industry and the business sector, for the initiation, funding and supervision of different kinds of fire research. Work is directed by a Programme Board and is performed in the form of projects at universities, research institutes, state authorities and private firms. The Secretariat of BRANDFORSK shares the premises of the Swedish Fire Protection Association, SFPA, and the SFPA is the principal and the party which enters into agreement with the State. The programme for the period 1997-1999 has been drawn up on the basis of both damage development and the trends in society which can be noted, and the evident fire problems of the interested parties and their need for fire research. The inputs in the programme have been broken down seven problem areas. In every problem area different project areas are set out, and these primarily specify the aim of the work. Our seven problem-areas are; Costs and benefits of fire protection measure. The role and behaviour of people and organizations Fire In buildings Fire in underground facilities Rescue operations fire in industries Fire and the environment. In comparison with previous fire research programmes, cost/benefit studies have been accorded higher priority, and this is also reflected in other problem areas. Grater Emphasis

  • The purpose of this study is to examine what are the important variables for information security compliance and whether the information security investment by the industry is different. To comply with the information security policies, the organization must establish measures to prevent or resolve information security incidents. This research process consists of four stages, and the analysis method was conducted with the categorical regression analysis and the correspondence analysis. The first analysis analyzed the independent variables that affect security regulations compliance. The rest of the analysis was conducted by industry in the order of security compliance regulations, manpower investment, and budget investment. As a result of the first analysis, this had positive effects on an organization and personal information protection awareness, joint operation organization of information protection, manpower and budget investment, corporate size, and industry. The correspondence analysis was conducted from the second analysis to the fourth analysis and it analyzed the differences in information security investment by industry. The second analysis showed that the construction industry, science and technology industry, and finance industry have higher compliance with security regulations than other industries. The third analysis showed that the financial industry and the science and technology industry were higher than other industries. The last analysis showed that the financial industry was higher than other industries. The theoretical contribution of this study provided the basis for updating the information security theory. The practical contribution of this study requires government support to reduce information security deviations by industry.

  • The U.S. Department of Defense, leading global cybersecurity policies, has two main cybersecurity frameworks: the Cybersecurity Maturity Model Certification (CMMC) for external defense industry certification, and the Risk Management Framework (RMF) for internal organizational security assessments. For Republic of Korea military, starting from 2026, the Korean version of RMF (K-RMF) will be fully implemented. Domestic defense industry companies participating in projects commissioned by the U.S. Department of Defense must obtain CMMC certification by October 2025. In this paper, a new standard compliance meta-model (R3C) development methodology that can simultaneously support CMMC and RMF security audit readiness tasks is introduced, along with the implementation results of a compliance solution based on the R3C meta-model. This research is based on practical experience with the U.S. Department of Defense's cybersecurity regulations gained during the joint project by the South Korean and U.S. defense ministries' joint chiefs of staff since 2022. The developed compliance solution functions are being utilized in joint South Korean-U.S. military exercises. The compliance solution developed through this research is expected to be available for sale in the private sector and is anticipated to be highly valuable for domestic defense industry companies that need immediate CMMC certification.

  • The high penetration level of inverter-based distributed generation (DG) power plants is challenging the low-voltage ride-through requirements, especially under unbalanced voltage sags. Recently, a flexible injection of both positive- (PS) and negative-sequence (NS) reactive currents has been suggested for the next generation of grid codes. This can enhance the ancillary services for voltage support at the point of common coupling (PCC). In light of this, considering distant grid faults that occur in a mainly inductive grid, this paper proposes a complete voltage support control scheme for the interface inverters of medium or high-rated DG power plants. The first contribution is the development of a reactive current reference generator combining PS and NS, with a feature to increase the PS voltage and simultaneously decrease the NS voltage, to mitigate voltage imbalance. The second contribution is the design of a voltage support control loop with two flexible PCC voltage set points, which can ensure continuous operation within the limits required in grid codes. In addition, a current saturation strategy is also considered for deep voltage sags to avoid overcurrent protection. Finally, simulation and experimental results are presented to validate the effectiveness of the proposed control scheme.

  • The coordination of a three-level supply chain consisting of a supplier, a retailer, and a discount outlet (DCO) is studied here. We assume that the product is sold in two consecutive periods a Normal Sales Period (NSP) and a subsequent Clearance Salvage Period (CSP). A benchmark case is studied Initially in which the supply chain is coordinated by a s1n91e agent. Thus, the supplier the retailer, and the discount outlet design a common system that allows centralized decision making about stocking quantities, markdown time schedules, and policies on disposing of leftovers to deliver the greatest possible expected supply chain profit. Next, we consider a decentralized supply chain. Here, decisions are made without coordination. The objective is to maximize an individual party's expected profits. The focus of the study is on the following questions: what factors make the coordination an effective approach for the supply chain? How do we coordinate the supply chain so as to maximize the supply chain Joint expected profit? These and other related study issues are explored in this paper.

  • After a long period of development and worldwide consultation, the London-based Joint Cargo Committee has revised the Institute Cargo Clauses (A), (B) & (C) and some ancillary Institute Clauses. The revision mainly include a clarification of the exclusions within the clauses, some modernization of the language of the clauses and new definitions of some terms. With these revisions, the coverage is widened to offer more protection to the assured. This may enable the widely used Institute Cargo Clauses to receive even greater worldwide acceptance. The following are the main changes in the new 2009 ICC compared with the 1982 ICC. 1. Insufficient or unsuitable Packing or Preparation(Clause 4.3): The revised clause is more favourable to the assured because under the revised clause this sub-clause is only applicable to (a) where packing or preparation is carried out by the assured or their employees or (b) packing or preparation takes place before the attachment of the risk. 2. Insolvency or Financial Default (Clause 4.6): The insolvency and financial default wording is incorporated in the revised clauses, making it more favourable to the assured. 3. Unseaworthiness (Clause 5): The revision is more favourable to the assured in that it limits the exclusion in relation to the unfitness of vehicles, vessels or containers to cases where the assured or their employees are privy to such unfitness. 4. Terrorism (Clause 7): A new definition of "terrorism" is introduced and the revised clause also widens the acts of an individual to encompass ideological and religious motives.

  • Objectives Oxidative stress, in which antioxidant proteins and scavenger protection are overwhelmed by reactive oxygen species (ROS) production, is recognized as one of central causes of disuse muscle atrophy. In this study, the hypothesis that oral treatment with Dangguibohyul-tang (Dangguibuxuetang) could attenuate immobilization-induced skeletal muscle atrophy was tested. Methods The hindlimb immobilization was performed with casting tape to keep the left ankle joint in a fully extended position. The Rats in Dangguibohyul-tang treated group (DGBHT) (n=10) were orally administrated Dangguibohyul-tang water extract, and rats of Control group (n=10) were given with saline only. After 2 weeks of immobilization, the morphology of right and left gastrocnemius muscles in both DGBHT and Control groups were assessed by hematoxylin and eosin staining. Results Dangguibohyul-tang water extract represented the significant protective effects against the reductions of the left gastrocnemius muscles weight and average cross section area to compared with Control group. Moreover, the treatment with Dangguibohyul-tang extract significantly enhanced the Cu/Zn-SOD activities in gastrocnemius muscle compared with Control group. Conclusions Thses results suggest that Dangguibohyul-tang has protective effects against immobilization-induced muscle atrophy by increasing the Cu/Zn-SOD activities in gastrocnemius muscle.

  • To devise a plan to efficiently control and cope with musculoskeletal disorders, this study conducted a self-administered survey among dental hygienists working at dental clinics in Daegu. The data were collected from December 1, 2013 to February 28, 2014, and drew the following conclusions. For body posture for medical procedures, at lower levels in their careers, the hygienists' head and back were more bent; at higher levels in their careers, the their shoulders, body and hips were more bent; and at higher levels in their careers, their assistance posture in general was more bent. Hygienists with longer years of experience had more pain in the neck and the arms/elbows. Respondents engaged in medical treatment services were more likely to have pain in their arms/elbows, and those engaged in assisting in medical treatment and consulting and insurance services were more likely to have pain in their necks. It is necessary to recognize the seriousness of musculoskeletal disorders, provide specific education through supplementary training and relevant seminars, and avoid repetitive use of the same muscle or joint through environmental improvement of dental clinics, and personal efforts should be made to maintain good posture.

  • Isolated acromial fracture is not common and it frequently accompanies fractures to the coracoid process and glenoid bone and also injuries to the acromioclavicular joint. Furthermore, most of these combined acromial fractures have minimal displacement, which needs no additional treatment other than protection for a certain period of time. We have experienced a case of isolated fracture of the posterolateral angle of the acromion, which we reduced and fixated using K-wire and cannulated screws. We report on the technical aspects and clinical results of this reduction and fixation, along with a review of the literature.
