The purpose of the study is to develop an index for basic management diagnosis of domestic industrial crafts companies. After the verification processes aimed at experts working in industrial crafts companies, the index of basic management diagnosis that has been researched and developed so far was turned out to be inappropriate to investigate the management of industrial crafts companies, in which the organized management system is not equipped due to their small-scale business environment. It is because the current index of management diagnosis was designed for diagnosis from the functional perspective. Therefore, in this study, the new index of management diagnosis was developed in order to diagnose the management of industrial crafts companies from the process perspective. This index is divided into three elements of Plan, Do, and See, which represents the management process cycle with focus on activities of industrial crafts companies. In addition, through literature study and Focus Group Interview (FGI) based on this index, detailed aspects and items of diagnosis, and checklists were emerged. This index of management is designed for the basic management diagnosis of industrial crafts, and it is possible to figure out management problems from diverse perspectives. For further research, the effectiveness of the index of management should be verified through diagnosing the management of industrial crafts companies and grasping management problems from varied perspectives.

In parallel with evolving information communication technology, M2M(Machine-to-Machine) industry has implemented multi-functional and high-performance systems, and made great strides with IoT(Internet of Things) and IoE(Internet of Everything). Authentication, confidentiality, anonymity, non-repudiation, data reliability, connectionless and traceability are prerequisites for communication security. Yet, the wireless transmission section in M2M communication is exposed to intruders' attacks. Any security issues attributable to M2M wireless communication protocols may lead to serious concerns including system faults, information leakage and privacy challenges. Therefore, mutual authentication and security are key components of protocol design. Recently, secure communication protocols have been regarded as highly important and explored as such. The present paper draws on hash function, random numbers, secret keys and session keys to design a secure communication protocol. Also, this paper tests the proposed protocol with a formal verification tool, Casper/FDR, to demonstrate its security against a range of intruders' attacks. In brief, the proposed protocol meets the security requirements, addressing the challenges without any problems.

Binary trans-activation (pOp/LhG4) system is one of the regulatory systems of transgene expression. The target gene expression is achieved by crossing the reporter plants with an activator in this system. In this study, we used the features of this system in Chinese cabbage as a way to protect genetic resources and new varieties. To establish pOp/LhG4 system in Chinese cabbage, we designed an activator (35SLhG41300), and reporter constructs (pOpGUSBart) and co-transformed using Agrobacterium. The transgenic plants were selected by antibiotics and the functional activity of pOp/LhG4 system was confirmed by GUS expression. To induce the tissue-specific function, we constructed pOp/LhG4 system (795LhGBart) using female tissue specific promoter (ProAt1g26795) of Arabidopsis. Co-transformed transgenic plants clearly showed tissue specific expression in Arabidopsis. The results suggest the possibility of the system's application of $F_1$ generation can be restricted by expressing the target gene to protect a new variety and genetic resource in Chinese cabbages.

In general, a non-explosive nylon wire cutting-based holding and release mechanism has been used to store and deploy deployable solar panels of CubeSat. However, with this method, accessing the solar panel's access port for charging the cube satellite's battery and electrical inspection and testing of the PCB and payloads while the solar panel is in storage is difficult. Additionally, the mechanism must have a reliable release function in an in-orbit environment, and reusability for stow and deploy of the solar panel, which is a hassle for the operator and difficult to maintain a consistent nylon wire fastening process. In this study, we proposed a pin-puller-based solar panel holding and release mechanism that can easily deploy a solar panel without cutting nylon wires by separating constraining pins. The proposed mechanism's release function and performance were verified through a solar panel deployment test and a maximum separation load measurement test. Through this, we also verified the design feasibility and effectiveness of the pin-puller-based separation device.

Naval Ships have a number of requirements related to performance. Naval ship acquisition takes a long time from initial planning to delivery, and various products such as drawings and reports are created. In complex systems, such as naval ships, it is difficult to maintain the required traceability through these outputs. The basic design of the ship is an important step to determine the specifications, performance, and equipment of the ship. It is necessary to apply the systematic requirements management process. The basic design manages the requirements in accordance with the systems engineering-based technical review process, but the actual system architecture design process is not presented. The traceability between the requirements and the functional and physical architectures of components is unclear. This paper examined how to design the system architecture required for specification and system design, and the design results were verified using SE-based technical review process for requirements management. A step-by-step process for designing a submarine system architecture is presented and verified using the SE technical review. This facilitates the specification of the requirements and system architecture design, and supports traceability management and verification of the requirements. The proposed process can be applied in various ships including submarines.

This study confirmed the potential of Punica granatum L. extract for functional activity verification and cosmetic development. The electron-donating ability of Punica granatum L. extract was shown 60.6% at a 1,000 ㎍/ml concentration. Its ABTS+ radical scavenging ability was shown 93.9% at a 1,000 ㎍/ml concentration. Additionally, the inhibitive effects of elastase and collagenase inhibition effects were measured as 30% and 47.2%, respectively, at a 1,000 ㎍/ml concentration. To determine the effect of Punica granatum L. extract on the proliferation of fibroblasts (CCD-986sk), cell viability was measured using a 3-[4,5-dimethyl-thiazol-2-yl]-2,5-diphenyl-tetrazoliumbromide (MTT) assay. As a result, survival rates of 130% or higher at a 500 ㎍/ml concentration or less were confirmed. According to the results of Western blot with Punica granatum L. extract, the expression inhibition rates of matrix metalloproteinase-1 (MMP-1), matrix metalloproteinase-2 (MMP-2), and matrix metalloproteinase-3 (MMP-3) were decreased by 23.2%, 81.9%, and 69.2%, respectively, at a 100 ㎍/ml concentration. Based on the results above, O/W liquid crystal cream with 0.1% Punica granatum L. extract was prepared. The stabilities were tested at 4, 25, 45, and 50℃. By checking the pH, change over time, and stability by temperature, it was confirmed that all were stable for one month. Thus, Punica granatum L. extract shows potential as a natural material for cosmetics.
