The F&EI technique is one of the risk assessments with many advantages. It can save time and effort compared to quantitative risk assessment (QRA). By using the evaluation result of this technique, it is possible to check the effectiveness of the investment cost. In addition, a relative risk ranking can be created and used to establish the facility management cycle and to prioritize investment. However, evaluating the target process can be evaluated more than the actual risk since the LCCF, a loss prevention measure, is too limited. In addition, calculating premiums via this method can result in excessive premiums, making it difficult to evaluate the risk precisely. Therefore, new safety guard was added to the LCCF of the F&EI risk assessment with reference to HAZOP and LOPA techniques. Newly added LCCFs are Deflagration arrester, Check valve, SIS, and Vacuum beaker, etc. As a case study, F&EI risk assessment was performed on Acetone storage tank of a API (Active pharmaceutical ingredient) plant to compare actual MPPD. The estimated loss amount was 592,558$ for the existing technique and 563,571$ for the improved technique, which was reduced by about 5% compared to the previous one.This proved that a more precise evaluation is possible and that the efforts for safety at the workplace are reflected in the evaluation results.

It has already been two decades or more ever since the shipping and its related industries began to mature in advanced shipping countries. During that period, such countries have made various attempts for the survival of the industries. The advent of the so-called flags of convenience in a big way for the purpose of replacing crew members of their own expensive seamen by those of developing countries and the emergence of ship management companies, which are literally engaged in the management of ships, are the results of such movements. Some countries have been making efforts, as measures for the continued existence of the maritime industries, to create new marine-related businesses without regard to the traditional concepts of the industries. The movement toward the restructuring of a maritime society in Norway is well known as a typical example of such endeavors. The business of marine consultancy relating to maritime safety management field in our country is also a business that came into existence in such a stream toward the revitalization of the maritime society. In this paper, as well as placing in focus the current picture and problems of marine industries in our country, we would like to present approaches to tackle these problems employed by advanced industrial nations in the West, that is, moves toward the revival of maritime communities. Next, we propose, as one of the answers to solve such problems, the further development of a consulting business which takes advantage of simulators. Lastly, we show specific examples of application of a simulator to the consulting business, while commenting on the effects of its use.

Construction is among the most dangerous industries with numerous accidents occurring at job sites. Following an accident, an investigation report is issued, containing all of the specifics. Analyzing the text information in construction accident reports can help enhance our understanding of historical data and be utilized for accident prevention. However, the conventional method requires a significant amount of time and effort to read and identify crucial information. The previous studies primarily focused on analyzing related objects and causes of accidents rather than the construction activities. This study aims to extract construction activities taken by workers associated with accidents by presenting an automated framework that adopts a deep learning-based approach and natural language processing (NLP) techniques to automatically classify sentences obtained from previous construction accident reports into predefined categories, namely TRADE (i.e., a construction activity before an accident), EVENT (i.e., an accident), and CONSEQUENCE (i.e., the outcome of an accident). The classification model was developed using Convolutional Neural Network (CNN) showed a robust accuracy of 88.7%, indicating that the proposed model is capable of investigating the occurrence of accidents with minimal manual involvement and sophisticated engineering. Also, this study is expected to support safety assessments and build risk management systems.

Supporting system design and construction management for the soft and hard rock layers with fractured zones are very important theme for the safety of temporary retaining wall, surrounding ground and structures in the urban deep excavation for the construction of subway, railway, building etc. The prevailing design method of supporting system for the soft and hard rock layers in the deep excavation is mostly carrying out by simplification without proper consideration for the characteristic of rock discontinuities. Therefore the behaviors of rock discontinuities and fractured zones dominate the whole safety of excavation work in the real construction stage, serious disaster due to the failure of temporary retaining wall can be induced in the case of developing large deformations in the ground and large axial forces in the supporting system. This paper introduces examples of deep excavation where the soft and hard rock layers with fractured zones were designed to be supported by shotcrete and rock bolt, deformations of corresponding ground and supporting systems in the construction period and increments of axial force in the upper earth anchors and strut due to the these deformations were investigated through detailed analysis of measurement data, the results were so used for the management of consecutive construction that led to the safe and economical completion of excavation work. The effort of this article aims to improve and develop the technique of design and construction in the coming projects having similar ground condition and supporting method.

최근 건축공사는 지가의 상승과 토지의 효율적인 이용을 위하여 지하층 깊이의 증가와 초고층화 되는 추세에 있으며, 건축시공 기술의 발달과 관리기법의 선진화에 따라 신속한 공사진행이 요구되고 있다. 그러나 이와 같은 시공기술과 관련시공법의 괄목할만한 발전에도 불구하고 초고층화와 신속한 공사진행을 뒷받침하여 줄만한 적절한 가설기법의 개발은 매우 미미한 실정이다. 공사중에는 건축물 외벽부에 대한 적절한 가설설비의 뒷받침이 없으면 건축물의 상층부에서 건축자재, 블록, 이물질 등이 낙하되어 분진 발생 등기 환경오염과 현장주변을 통행하는 사람이나 차량 등에 피해를 입히는 사고가 발생할 수 있으며 작업자의 추락재해와 같은 사고기 위험성도 높아지게 된다. 이에 본 연구에서는 분진, 낙하, 추락, 보양 등의 문제점을 해결하기 위하여 건축공사용 안전펜스공법(SCfence)을 제시하였으며, 이 공법은 건축물의 외측에 유도용 레일을 부착하여 고정시키고 이 유도용 레일을 따라 안전펜스가 승강하여 이동이 가능하고 건축물의 외부를 완전히 방호할 수 있도록 개발되었다. 또한 개발공법을 현장에 적용한 결과, 안전성 확보와 원가절감의 효과가 기존공법보다 우수한 것으로 나타났다.

There are growing needs for improving the general performances of the domestic working environment evaluation organizations. For this purpose, introduction of laboratory accreditation program has been suggested. This study was conducted as a part of this effort. With a questionnaire developed in accordance with the ISO/IEC 17025, the current status of industrial hygiene (IH) laboratories in terms of manpower, management and technical aspects. The results of this study were as follows: 1. The average working staffs' number of the working environment evaluation organizations was $6.8{\pm}3.3$ persons. In addition, 49% of all organizations are run by less than 5 persons. This suggests that manpower of Korean IH laboratories is very limited. 2. IH laboratories surveyed in this study obtained 53% of the points by the international standard. And there is significant correlation between the number of staffing and total scores (P<0.05). 3. The period of work experience is one of the most important factors to determine the working capability. The average year of work experience of the laboratories' directors was $13.5{\pm}5.3$ years. Directors with more wok experiences obtained higher scores on the questions that ask to prove the appropriateness of the research methodology (p<0.05). 4. As for academic qualifications of laboratory directors, 14% had Ph.D., 31% with Master's, 29% with Bachelor's, and 4% had Associate degree. There was significant correlation between the total scores and the general managers' academic background (p<0.05). The 27% of laboratory directors have majored in either industrial hygiene or health, 8% majored in medicine, another 8% majored environmental studies, and 6% majored in chemistry. 5. Only 14% of all IH laboratories surveyed employ directors with Certified Industrial Hygienist licence, 41% have general managers with Certified Associate Industrial Hygienist (Level 1) licence, and 45% of all laboratories either employ directors without relevant qualification or did not respond. When the laboratory manger holds relevant qualification, laboratory health and safety management was better (p<0.05). 6. When compared to the general international standard in terms of the management, and 55% in terms of technological level.

In Korea, the school foodservice program has been expanding rapidly in recent years, partly as a result of increased government support. With the growth in the number of schools offering foodservice programs, food safety and sanitation concerns have been increasing. To assist with program improvement, a situation analysis was carried out, with the focus on equipment and sanitary management of school foodservice programs under flour different management systems. A questionnaire was mailed to the foodservice directors of 234 randomly selected schools chi[h included elementary, middle and high schools at the national level. Among them, one hundred and sixty-five responses reasonably completed were used for the analysis. This study classified each school's foodservice management into one of four types : independent-conventional, independent-commissary, contract-conventional, and contract-delivery. The results show that the monitoring of employees' health and personal hygiene, and employees' sanitary education was well conducted, but that the sanitary education of the voluntary parent workers was largely ignored. Eighty-six percent of the schools had their drinking water tested for sanitation, and the results showed that more effort is needed in careful management of drinking water in order to prevent foodborne illnesses and bacillary dysentery. In general, contract management showed lower scores in foodservice equipment and their efficiency, compared with independent management. A relatively high number of schools on the contract-delivery management system employed nurses and leachers instead of dietitians and foodservice directors. The adoption of the HACCP (Hazard Analysis Critical Control Point) system was lowest in contract-conventional and contract-delivery management systems, and highest in elementary schools using the independent-conventional system.

This paper conducted an empirical study to identify the causal relationship of factors affecting the purchase intention of automobiles from the customer's point of view. This study sets the purchase intention as a result variable and constructs a causal model with brand image, product attributes (exdogenous variable), and customer value (endogenous variable) as a cause that affects purchase intention. The results of this study are summarized as follows. First, the symbolic image of the brand was found to have a very significant effect on customer value (p=0.01), and the external attribute of the product also had a significant effect on customer value (p=0.1). Second, customer value was found to have a very significant effect on purchase intention (p=0.01), and the functional image of the brand also had a significant effect on purchase intention (p=0.1). Third, there is a strong positive (+) correlation between the functional image of the brand and the symbolic image of the brand, the intrinsic attribute of the product, and the external attribute of the product, and also between the symbolic image of the brand and the intrinsic attribute of the product and There was also a positive (+) correlation between extrinsic attributes. Therefore, in order to increase customer value, automobile manufacturing companies have a functional value of products from a customer-oriented perspective. It is judged that every effort should be made to maintain a lasting relationship by grasping the values of customers, which are social values, emotional values, situational values, and cognitive values.
