This paper deals with Activity Analysis Method that is important procedure in Activity Based Costing System Implementation. There are many existing Activity Analysis Method, for example Interview, Questionnaire, Specialist Discussion and Work Measurement. Activity Analysis Data gained through this method has high reliability but this method bring about high cost. In case that certain company needs a strategic costing system, Activity Analysis Method which has high reliability will be need. But, if companies want the costing system as a internal decision making tool only, they need to design the ABC system fast and cheaply. This paper explains that Activity Analysis using existing finn material is good alternatives. So, this paper show the feasibility of Activity Analysis using existing firm material with comparing between job description, job specification information and Activity Analysis information.

Recently, the blockchain platform is changing the art market. Changes are taking place in many areas, including artists, collectors, art investors, and auction. The platform that provides distribution history information on artworks on a blockchain basis can be used when information on the work history is suspected or needs verification, and can be used to manage the distribution history information of stolen and lost artworks and confiscated artworks by the police. Several companies currently operate these platforms, but they operate various blockchain platforms according to their contents. In this paper, we will compare and analyze features of artworks blockchain platform.

Objectives: In this study, we aimed to examine the dysphagia knowledge, preventive attitudes toward dysphagia, and educational needs concerning geriatric oral health, of dental hygienists, and to provide fundamental information for recognizing the necessity of knowledge and education concerning geriatric oral health and for increasing educational needs. Methods: From April 1 to June 30, 2022, a questionnaire survey was administered to 198 dental hygienists via an online link. SPSS Statistics ver. 22.0 was used to conduct the frequency analysis, t-test, one-way ANOVA, Pearson's correlation coefficient, and multiple regression analysis. Results: Regarding the difference in knowledge of dysphagia depending on general characteristics, the study participants had more knowledge of dysphagia when they were more interested in dysphagia and had a higher geriatric treatment frequency. The preventive attitudes toward dysphagia were strong in those who graduated from graduate school or higher, had more prevention and education at work, became more interested in dysphagia, received more education about dysphagia, had intention to receive additional education on dysphagia, and had a higher geriatric treatment frequency. Positive correlations were observed between knowledge of dysphagia, preventive attitudes toward dysphagia, and educational needs related to geriatric oral health. The educational needs related to geriatric oral health were found to be, significantly and positively influenced by preventive attitudes toward dysphagia, having master's degree or higher, knowledge of dysphagia, and intention to receive additional education on dysphagia. Conclusions: It is necessary to improve the quality of oral health services offered to older patients by having accurate knowledge of dysphagia implementing appropriate prevention practices for dysphagia, and understanding the educational content needed by the oral hygienists and developing an effective education program to enhance their professionalism.

A security risk analysis provides all information system with the capability to investigate and estimate the status of its security, and gives a guideline for establishing a safeguard against any means of security threats. The information system needs tile judicious and accurate why for performing a risk analysis since security policy and risk analysis of tile information system are based on risk analysis, The risk analysis is composed of two methods. mathematical approach and diagramming technique. Mathematical approach cannot yield a precise description of the real world. However, diagramming technique is more pragmatic since it overcomes this limitation. In this paper, we studied tile security risk analysis methods proposed in overseas such as INFOSEC [4], SRAG [5], FIPS65[6], and JRAM[7].

The management of organizational Human Resource is steadily shifting away from pure hierarchical to market mechanisms that involve external vendors. HR Business Process Outsourcing (BPO) has recently emerged as a significant administrative innovation in an organization's strategy. Our paper attempts to understand firm-specific factors influencing the scope of HR BPO needs. Study results show that IT maturity and firm size are influential factors on the scope of HR BPO needs. We hope that our attempt at empirically examining and predicting this emergent phenomenon will stimulate others to look at this important strategic challenge facing firms from a theoretical perspective. Such research initiatives will allow us not only to better understand this complex phenomenon, but also to drive useful management prescriptions grounded on theory-based research.

Three-dimensional integrated circuits (3D ICs), starting with memory cubes, have entered the mainstream recently. The benefits many predicted in the past are indeed delivered, including higher memory bandwidth, smaller form factor, and lower energy. However, 3D ICs have yet to find their deployment in aerospace applications. In this paper we first present key design tools and methodologies for high performance, low power, and reliable 3D ICs that mainly target terrestrial applications. Next, we discuss research needs to extend their capabilities to ensure reliable operations under the harsh space environments. We first present a design methodology that performs fine-grained partitioning of functional modules in 3D ICs for power reduction. Next, we discuss our multi-physics reliability analysis tool that identifies thermal and mechanical reliability trouble spots in the given 3D IC layouts. Our tools will help aerospace electronics designers to improve the reliability of these 3D IC components while not degrading their energy benefits.

Advanced Encryption Standard (AES) is widely used for protecting wireless sensor network (WSN). At the Workshop on Cryptographic Hardware and Embedded Systems (CHES) 2012, G$\acute{e}$rard et al. proposed an optimized collision attack and break a practical implementation of AES. However, the attack needs at least 256 averaged power traces and has a high computational complexity because of its byte wise operation. In this paper, we propose a novel double sieve collision attack based on bitwise collision detection, and an improved version with an error-tolerant mechanism. Practical attacks are successfully conducted on a software implementation of AES in a low-power chip which can be used in wireless sensor node. Simulation results show that our attack needs 90% less time than the work published by G$\acute{e}$rard et al. to reach a success rate of 0.9.

The purpose of this study was to identify the need for the housing consultation and information about housing in 6 cities except Seoul. This study examined the relations among socio-demographic characteristics, housing characteristics, and the level of need for the housing consultation and information. The number of 629 housewives were interviewed in Pusan, Daefeon, Inchon, Daegu, Kwangju, and Jeonju. The data were analysed by statistical methods such as frequencies, means, and logistic regression analysis. The results showed that the significant variables related to the needs for the housing consultation were the age, education level, and the experience of housing consultation. Respondents were required urgently the parts of housing environment and housing maintenance and repair.

This study focused on the determining factors of foreign workers employment in Korean companies. To improve our national enterprise's work outcome, it is necessary to establish a rational employment management policy plan so that the Korea can promote influx of foreign workers who have appropriate job skills and are hard-working and well suited for cultural environment. Accordingly, the companies need to develop the program by considering following. First, the duty of skilled foreign workers for employment is an important determinant factor and thus the targeting for foreign workers is necessary to proceed with pre-paced training. Second, reflecting the cultural characteristics of migrant workers, a cultural adjustment program needs to be developed. In this regard, the national program of screening foreign workers at the government level and the adaptation program needs to be launched suitable for local environment.
