The advancement of information and communication technology has caused a few dysfunction such as hacking. To keep an organization from a harmful hacking, demands for cryptographic modules have been increased. However, the evaluation criteria of cryptographic modules in Korea have been less firmly established. It is difficult for the consumers of cryptographic module to choose an appropriate cryptographic module, and to establish interoperability between applications and cryptographic modules. This study analyzes evaluation criteria, evaluation processes and evaluation policy of CMVP(Cryptographic Module Verification Program) in the advanced countries. The paper suggests a policy for Korea CMVP, in resulting a provision of foundations for international standard and cooperations for international cryptographic policies and systems.

In 2021 One Tambon One Product (OTOP) food products reached $3,447 billion domestically and $200 million internationally. Mirroring Japan's highly successful OVOP (One Village One Product) poverty reduction and rural employment program, Thailand's OTOP program has since become a global model of success as well. From May through June 2022, OTOP snack food vendor entrepreneurs were contacted and asked to contribute their opinions about what factors affected their enterprise's food product quality. Using systematic random sampling across six Thai regions, 311 export entrepreneurs, production managers, and marketing managers participated. The results revealed that product innovation (PDTI), process innovation (PCSI), packaging design (PKD), and the 4P marketing mix (4PMM) all positively influenced OTOP snack food product quality (PDQ), which, when combined, had a total effect R² value of 27%. Also, the latent variable TE values for PDTI, PKD, 4PMM, and PCSI, were 0.38, 0.29, 0.22 and 0.11, respectively. Seven of the nine hypotheses examined were supported, with packaging design (PKD) determined to have the greatest influence on the 4P marketing mix (4PMM).

Ceramics are becoming one of the most important materials due to its good mechanical properties such as high strength, hardness, chemical safety, and high modulus of elasticity. Ceramics have been used widely as a material not only for construction, but also for vehicles, planes, and bones for the human body. Despite these advantages, ceramics have some limitations in actual use due to its brittle fracture characteristic. In order to develop ceramic belt in this study, the data regarding stiffness and strain is necessary. For this purpose, the sensitivities of maximum stress value and displacement are analyzed by applying the load change on ceramic belt with finite element method program.
