  • With the development of industrial technology and science, production and manufacturing facilities have been enhanced and improved, and the importance of the safety of workers has also been regulated and limited by various safety management methods. As a way to secure the safety of the workers from the production facility, the fail-safe and fool-proof methods are now being applied. Any possible insecure behavior and unsafe conditions can be removed by adopting the standards and specifications that are now secure the safety of workers and equipment. This research analyzes EN ISO 13849-1 international and European standards during CE certification. In order to secure acceptable reduced risks, the risk assessment process of ISO 12100 and the processes for reducing its risk are applied. In the current ISO 13849-1 standard, the criteria for the required performance level PLr (Required Performance Level) for the applicable risk and safety functions through the risk assessment are subjective and not subdivided. Therefore, the evaluation criteria are likely to cause judge's judgement error due to qualitative judgement. This research focuses on evaluation and acceptable performance level setting for the safety circuit of the equipment. We propose an objective and specific evaluation criteria to secure safety, and the proposed evaluation criteria are applied to the case study of the safety circuit for the equipment. In order to secure the safety of the entire safety circuit, the improvement of the MTTFd and DC level related to the SRP/CS (Safety-Related Parts of Control Systems)' lifetime is required for the future research.

  • Corporations report their economical, environmental, social influences and achievements through sustainability reports. Apart from the financial reports, which are subject to legal restrictions, sustainability reports inform non financial achievements of a corporation, thus the reliability of the information is solely dependent on the corporation itself. The current sustainability reports are of types that cannot include proof or source of the index data, thus they are tended to be regarded as means of publicity. The reliability of the reports is often questioned. This research applied the concept of Evidence-Based Accountability, which will allow the confirmation of accountability through records including contents and context of the tasks. Evidence-Based Accountability means producing and accumulating witness records of actions, then managing the records as usable information and use them as accountability information. Index data from sustainability reports of domestic corporations and web based reports of Vodafone was reviewed. Measures to link task records as proof of index data was studied. To make this possible, record production and acquisition system was redesigned in order to secure required records as evidence. Linked build-up of SR system and RMS was proposed. The proposed system will allow collection and management of records as SR accountability information, and provide the data when necessary. Also, corporate infrastructure was proposed. This infrastructure will build a professional records management system in stages, through organizational system and regulations. Cooperation of staff in this infrastructure will support reliable corporate accountability.

  • Oiled paper (Yuji, 油紙) is an oil impregnated paper which was one of the daily necessities in Korea. As there has not been any accurate research on this subject, this study examined the literature from the Joseon Dynasty to study its origin, nomenclature, usage and production process. Goryeodogyeong (高麗圖經) and Goryeosa (高麗史) allowed the estimation that the origin of oiled paper was the Goryeo Dynasty, but the records of oil and paper in Samguksagi (三國史記) and Nihon Shoki (日本書紀) indicate the possibility that the production of oiled paper can be traced back to the 7th Century. The nomenclature and the usage of oiled paper in the Joseon Dynasty were examined through the Annals of Joseon Dynast (朝鮮王朝實錄), Ilseongnok (日省錄) and Seungjeongwonilgi (承政院日記), while the Royal Protocols of the Joseon Dynasty (Uigwe, 儀軌) and Takjijunjeol (度支準折) together with other literature were examined for its market value, use and materials. The literature from the Joseon Dynasty indicate that oiled paper was used for various everyday commodities with its waterproof, damp-proof and transparent properties and called in various ways according to its use and production process. This study studied the literature on oiled paper from the Joseon Dynasty, but the studies on the restoration of traditional oiled paper are still needed. Therefore, it would be necessary to study the traditional oiled papers in combination with the study of oiled paper relics, the reproduction of traditional oiled paper samples, and the case study of the papermaking masters who have been producing the traditional oiled papers.

  • The advent of the handheld camera has dramatically transformed film production and consumption in countless ways. French director and theorist, Alexandre Astruc focuses on the development of 16mm camera and foretell film will be used as a tool to realize the personal vision of the author like other art. As proof of his claim French New Wave and Cinéma vérité create the film with handheld camera on the real location to capture new reality. Their films are distinguished itself from other films made by conventional Hollywood studios. Similarly, John Cassavetes in the United States began to focus on the handheld camera. Since then the handheld camera has become one of the popular shooting methods. Especially, handheld camera are noted for their agile movement and mobility as a way to capture various realities. However, with the advances in technology, lighter cameras and higher resolution have changed in different ways. The technology is neutral, one shooting method does not serve for one philosophy or ism. At one time, handheld shooting is now used as not only a means to capture the real world but also a tool to mimic a realistic feeling.

  • The effects of alcohol concentration (30% 45% and 60%) on quality changes of maesil (Prunus mume) liqueur during leaching and ripening for 5 months were examined. Total acidity, pH and color of the liqueur generally increased with an increase alcohol concentration for 2 months. Thereafter the significant change did not occur. The contents of reducing sugar and polyphenol in the liqueur increased with an increase alcohol concentration and ripening periods. The major components of free sugar in maesil liqueur were fructose, glucose, sucrose and maltose. The content of fructose and glucose were higher than those of sucrose and maltose regardless alcohol concentration. Sucrose and maltose did not detect in the liqueur after leaching and ripening for 2 months. The major components of organic acid in maesil liqueur were citric, lactic, malic, and acetic acids. The optimal alcohol concentration was 45% and the duration of leaching and ripening was about 2 months for production of high-proof maesil liqueur.

  • MFD (Make up Film Deterioration) is a gradual deterioration of applied make up and is a common problem experienced by most foundation users. Our investigation revealed that for 64% of all make up users MFD is their greatest consern is using foundations. Known that the primary cause of MFD is sebum secretion. We observed that the length of time prior to onset of MFD in people who produce high level of sebum varies significantly from person to person. This suggests that other factors besides quantity of sebum production can affect MFD. Control over this factor would, we believe, be key to developing longer-lasting makeups. We studied the relationship between MFD and skin surface conditions. Our study revealed that furrows on the skin surface affect MFD significantly. Sebum reaches the skin surface from sebaceous glands and flows along furrow on the skin. If there are many deep furrows, it takes longer for sebum to overflow. But if the furrows are few or shallow, sebum quickly overflows and spreads over the skin surface where it can degrade the make up film. Therefore even when the volume of sebum produced is the same, the rate of MFD will be different depending on the number and shape of the furrows. A longer-lasting foundation could be produced by matching personal skin condition, but this would be very difficult because individual variations in texture are very large. Therefore we approached the problem by attempting to impose sebum resistance in under make up and foundation. We have developed two new materials and make up products based on our theory. A new fluoroalkyl acrylate-methacrylates copolymer designed for incorporation in under make up is extremely sebum resistant and sweat proof. Another new acrylate polymer designed for inclusion in foundation absorbs sebum and changes to a solid. Usage tests confirm it is possible to reduce MFD by using under make up and foundation which incorporate our new materials to cover where skin furrows are few or shallow
