  • The management of safety at sea is based on a set of internationally accepted regulations and codes, governing or guiding the design and operation of ships. The regulations most directly concerned with human safety and protection of the environment are, in general, agreed internationally through the International Maritime Organization(IMO). IMO has continuously dealt with safety problems and, recognized that the human element is a key factor in both safety and pollution prevention issues(IMO, 2010). This paper proposes a human error analysis methodology which is based on the human error taxonomy and theories (SHELL model, GEMS model and etc.) that were discussed in the IMO guidelines for the investigation of human factors in marine casualties and incidents. In this paper, a cognitive process model, a human error analysis technique and a marine accident causal chains focused on human factors are discussed, and towing vessel collision accidents are analyzed as a case study in order to examine the applicability of the human error analysis technique to marine accidents. Also human errors related to those towing vessel collision accidents and their underlying factors are discussed in detail.

  • The importance of ozone monitoring has been growing due to the polar ozone depletion and increasing tropospheric ozone concentration over many Asian countries, including South Korea. In-situ measurement of the vertical ozone structure has advantages for ozone research, but observations are not sufficient. In this study, ozonesonde measurements were performed from October to November in Yongin during the GMAP (The GEMS Map of Air Pollution) 2021 campaign. The procedure for ozonesonde preparation and initial analysis of the observed ozone profile are documented. The observed ozone concentrations are in good agreement with previous studies in the troposphere, and they capture the stratospheric ozone distribution as well, including stratosphere-troposphere exchange event. These balloon-borne in situ measurements can contribute to the evaluation of remote sensing measurements such as Geostationary Environment Monitoring Spectrometer (GEMS). This document focuses on providing essential information of ozonesonde preparation and measurement for domestic researchers.

  • The object is to study the influence Korean ornaments had on the Japanese during the THREE KINGDOM PERIOD. In ornaments(Earrings Necklaces Bracelets Rings) also we can find commonness between Korean and Japan. CHIZASIL( a gardenia seed) and heart shaped of Earrings the use of gems in Necklaces engravings of abdomen on Bracelets and rhomb-shaped Rings all these are common between Korea and Japan. And the same time we can that our country was superior to Japan ornaments.

  • This study is concerned with a comparative linguistic analysis of the Manchu costume terminologies. The Manchu costume terminologies revealed the elements Hebrew, Norweygian, English, Assyrian, Chinese, American Indian, Sanskrit, Tatar, Turkestan, Greek, Arabic, Indian, Kashmiri. The most influential elements of the Manchu costume terminologies were the Chinese costume terminologies. specifically, the elements of the Chinese costume terms were found in the terminologies of the fabrics, the gems and the precious stones. Also the influence of the Mongolic costume on the Manchu costume terminologies appeared in this study.

  • In this study, we conducted the kinetic hydration modeling of OPC and the final product according to the substitution ratio of GGBS by using the geochemical code, GEMS, in order to calculate the thermodynamic equilibrium. The thermodynamic data was used by GEMS's 3rd party database, Cemdata18, and the cement hydration model, the Parrot & Killoh model was applied to simulate the hydration process. In OPC modeling, ion concentration of pore solution and hydration products by mass and volume were observed according to time. In the GGBS modeling, as the substitution rate increases, the amount of C-S-H, which contributes the long-term strength, increases, but the amount of Portlandite decreases, which leads to carbonation and steel corrosion. Therefore, it is necessary to establish prevention of some deterioration.

  • Business process should support the execution of collaboration process with agility and flexibility through the integration of enterprise inner or outer applications and human resources from the collaborative workflow view. Although the dependency of enterprise activities to the automated system has been increasing, human role is as important as ever. In the workflow modelling this human role is emphasized and the structure to control human error by analysing decision-making itself is needed. Also, through the collaboration of activities agile and effective communication should be constructed, eventually by the combination and coordination of activities to the aimed process the product quality should be improved. This paper classifies human errors can be occurred in collaborative workflow by applying GEMS(Generic Error Modelling System) to control them, and suggests human error control method through hybrid based modelling as well. On this base collaborative workflow modeling tool is designed and implemented. Using this modelling methodology it is possible to workflow modeling could be supported considering human characteristics has a tendency of human error to be controlled.

  • Maritime safety and marine environmental protection are the most important topic in marine society. But, so many marine accidents rave been occurred with the development of marine transportation industry. On the other side, ship is being operated under a highly dynamic environment and many factors are related with ship's collision Nowadays, the increasing tendency to the human errors of ship's collision is remarkable, and the investigation of the human errors has been heavily concentrated. This study analysed on the human errors of ship's collision related to the negligence of lookout and classified basic error type using GEMS(Generic Error Modeling System) dynamic model.

  • Slips and falls are associated with many public injuries in Korea. It is also estimated that slipping are major contributors to slip, trip and fall injury burden. The primary purpose of the present study is to determine if, and to what extent, the standard could be improved in present environment. In order to fulfill our objective, the regulations in Korea and foreign countries were investigated and reviewed. Many kind of standard, mandatory documents and guideline were also reviewed. And then, regulations, standard, guideline etc. reviewed were compared with each others. Also, some criteria was developed in this study. Standard and criteria developed in this study will help to prevent slip, trip, and fall injuries.

  • A number of screening tools have been developed to evaluate the human balance capability. Many of them were designed to identify the elderly with falling risk. Three different screening tools, which have been well used many clinical fields, were used in this study. The purpose of this study was to evaluate balance capability in facilities maintenance workers in korea. There were no statistical significance between male and female when evaluated with three different screening tools. However, significant differences were found among the age groups irrespective of gender when evaluated with three different screening tools. The results of three different screening tools in korea showed poor values compared with previous results. These results revealed that facilities maintenance workers faced more critical falling risk in korea.

  • 현재 전세계적으로 10,000여개 이상의 실험실에서 생물공학적인 연구가 진행중에 있고, 200여개 이상의 회사에서 생물공학을 이용한 제품이 만들어지고 있다.(Saftlas, 1984). 이와같은 제품으로 생물농약(예, 모기억제에 사용되는 Bacillus thuringiensis var. israelensis 등)이라든가 insulin, 성장호르몬, lymphotoxin및 항암제등의 의약품(Saftlas, 1984)과 식물품종개량제(예, 질소 공정의 vector로 사용되는 Agrobacterium tumerfaciens의 Ti Plasmid)(McDanial, 1981 ; Shaw, 1986) 등이 있다. 그러나 최근 미생물 생태분야에서는 이와같이 만들어진 미생물들 (genetically engineered microorganisms : GEMs)이 자연 생태계에 유출되었을때 야기될 가능성이 있는 biohazaed에 대하여 관심이 집중되고 있다. (Curtiss, 1976 ; Sharples, 1983 ; Rissler, 1984). 토양환경에서 GEM이 유전물질을 전달항 수 있는 기작은 크게 conjugation, transduction, transformation 등이 알려지고 있다. 여기서는 주로 토양환경에서 transformation에 의한 유전물질의 전달과정에 대한 최근 연구동향을 간단히 기술하고자 한다.
