  • Cobots are industrial robots with greatly enhanced safety functions that enable them to work in the same space with workers without protector. Cobots are regulated by the Industrial Safety and Health Act and must be certified according to the manufacturing stage, installation stage and usage stage. The ISO 10218-2 standard applied in the installation phase is difficult to apply in the field. Therefore, it is necessary to develop a risk assessment method based on ISO 12100 standard. This paper proposes a new methodology that combines 'JSA' and 'What-if', which reflects the human error and the lack of known risk factors. Accordingly, a new risk assessment template was proposed and the effectiveness of the developed new template was examined. The current cobot safety regulations need to be unified with safety inspections scheme, and robot safety experts and infrastructures need to be expanded and Robot safety regulations should be unified to 'Robot Act'. Based on this research, risk assessment methods suitable for the field need to be developed additionally, and robot safety regulation needs to be transformed to promote the industry.

  • Thus in order to have a better understanding about the KSA(Korean Security association) and to express opinions on its role and security, this paper introduces and discusses about All Japan Security Service Association(AJSSA), which is the prototype of the KSA. There are several positive aspects to consider the introduction of, when these two associations are compared: the traffic security, a supporting member, ex-high-ranking police executive directors practically run AJSSA. These are to enhance financial ability and to promote better relationship with police. KSA needs to improve such relationship and to diversify activities as well. In addition, not just dismissing their duty by giving them the license, AJSSA provides several educations to revitalize the related people so that they can deal in effective and productive services. In another words, JSA perceives it is indispensable to educate the relevant people in the business. In contrast, it is reality that KSA has not put much emphasis on educations. Concisely, the most prompt issue is it should be more beneficial to its members by strengthening itself. Not simply following the example of foreign cases, but putting diverse efforts, KSA can make it substantial and stabilize future private security market in a long term.

  • Film color is equivalent to other elements of film, including narrative, and has a textual meaning according to the identity of expression. In general, red has a function of focusing attention, and the meaning derived from it is diffused. In the interaction of text and context, the function of concentration and the meaning of diffusion can be presented. The concept of concentration and diffusion is shaped by the relationship between independent colors, colors and other cinematic elements, and interactions between colors. In order to confirm this, this study analyzes a series of popular Korean films, how film colors interact, and in particular, the concentration function of red and the meaning of proliferation. The results of this study are as follows. First, in Korean popular films, at its most basic, red symbolizes a nation, a people, and a nation. The red of nationalism surrounding ethnicity, nationality and country visualizes ideology and conflict. The purpose of an individual or group, the relationship between the offender and the victim is mediated through red. The flag, the name tag, the costume appearing in the film are red. This can be seen in films such as Train to Busan, Assassination, Masquerade, Miracle in Cell No.7, Brotherhood of War, Northern Limit Line, Joint Security Area, Welcome to Dongmakgol, and May 18. Second, the red color attached to the female body fixes or strengthens socio-cultural sexuality and gender. The examples are films like Ode to My Father, The Thieves, The Host, Purpose Of Love, Sunny, Like A Virgin, Forbidden Quest, Untold Scandal, Bewitching Attraction, and Ssanghwajeom. Third, the blood red in Korean films is a visual device that directs magical horror, anger, and asceticism. Such films include The Neighbors, Bunshinsaba, R-Point, A Tale Of Two Sisters, Whispering Corridors, The Uninvited, Thirst, SECTOR 7, Asura:The City of Madness, The Tiger, Veteran, and so on. Fourth, red of tears constitutes the specific emotions such as a beautiful desire and a brilliant tragedy in films like King and The Clown, Oldboy, Memories of Murder, 26 Years, The Attorney, Unbowed, Sympathy For Lady Vengeance, Happy End, Punch, Calling, The Yellow Sea, and He's on Duty.

  • This study evaluated quality characteristics of soybean fermented by selected lactic acid bacteria, which were the enzyme strains with high antimicrobial activities isolated from traditionally prepared soybean paste. We determined total aerobic and lactic acid bacteria counts, protease and amylase activities, reducing sugar and amino-type nitrogen contents, and the amounts of amino acids, organic acids, and aroma-compounds. The total aerobic bacteria counts in soybean fermented with strain I13 ($7.75{\times}10^9CFU/mL$) were the highest among all the strains analyzed. Lactic acid bacteria numbers were $2.85{\times}10^9$ to $4.35{\times}10^9CFU/mL$ in soybean fermented with isolates. Amylase and protease activities of the JSB22 sample were the highest among all sample. Reducing sugar and amino-type nitrogen contents of soybean fermented with JSB22 (1.23%, 94.52 mg%) were highest. Total amino acid content of the samples was 15.88-17.62%, and glutamic acid, aspartic acid, leucine, lysine, and arginine were the major amino acids. Lactic acid (0.82-3.65 g/100 g), oxalic acid (22.74-63.57 mg/100 g), and fumaric acid (2.88-6.33 mg/100 g) were predominant organic acids. A total of 39 volatile aroma-compounds were identified, including 2 esters, 5 ketones, 7 alcohols, 14 hydrocarbons, 2 heterocyclic compounds, 4 acids, and 5 miscellaneous compounds. These results represent useful information for the development of a starter (single or complex) and will be used for production of functional fermented soybean foods.
