De facto standards can be divided into the U.S. group standards' and 'forum and the consortium standard. mainly applies to high-tech industry forums, and a consortium standard of the industry given the nature of the standard are frequently revised, the country Due to the introduction of standard time. Economic loss to consider when in reality, the introduction of national standards of the United States is limited to the desirable standard, and the fact the actual award of standards, national standards, or if you want to introduce standard, each of depending on the type of attitude and strategy for standards by category, based on the characteristics of each body strategy and are needed. Through this study on utilization of de facto standards for national standards, it is researched that major de facto standards bodies status and domestic industrial fields which need utilization of de facto standards for national standards. Through overseas Case, effective usage of de facto standards will be obtained.

The purpose of this study is to explore the implications for the systematic operation of the AI curriculum by analyzing the current status of the AI major curriculum in universities. To this end, This study analyzed the relevant curriculum of domestic universities(a total of 51 schools) and overseas QS Top 10 universities based on the industry demand-based standard of AI major curriculum developed through prior research. The main research results are as follows. First, in the case of domestic universities, Python-centered programming subjects were lacking. Second, there were few subjects for advanced learning such as AI application and convergence. Third, the subjects required to perform the AI developer job were insufficient. Fourth, in the case of colleges, the ratio of AI mathematics-related subjects was low. Based on these results, this study presented implications for the systematic operation of the AI major education.

Purpose: Obesity is already a major clinical problem in Korea, so obesity prevention and treatment practices are gradually interested in Korean Medicine doctors. Moreover subjective body shape image entered as a important medical topic recently. To make a graph system for clinical tool which based on the Korean national standard physical scale. Methods: Physical data of the girth of upper arm, abdomen, hip, buttock, flank, calf, and body weight were statistically analyzed, which collected through the fifth national standard physical scale research. And then reviewed those statistical validation. Results: Relationship of the each body scale data and those graphs were fit and right statistically. Conclusion: These new achieved graph system of Korean standard body scales could be adopt as a useful clinical tool for body image related patients such as obesity, PCOD and postpartum patient.

Current standard for T-DMB Automatic Emergency Alert Service(AEAS) contains controversial problems in service signaling. In this paper, we first describe two important characteristics of AEAS which hinder normal MCI service signaling: Common Service and Aperiodic Service. Next, we propose four method to overcome the problems, followed by the characteristics of each method. In this analysis, current T-DMB standard, the broadcasting system, and receivers are the major player to decide the optimum service signaling method. This analysis will be also applied to the design of transmission standard for other media such as cable, satellite, the Internet, etc.

Slips and falls are associated with many public injuries in Korea. It is also estimated that slipping are major contributors to slip, trip and fall injury burden. The primary purpose of the present study is to determine if, and to what extent, the standard could be improved in present environment. In order to fulfill our objective, the regulations in Korea and foreign countries were investigated and reviewed. Many kind of standard, mandatory documents and guideline were also reviewed. And then, regulations, standard, guideline etc. reviewed were compared with each others. Also, some criteria was developed in this study. Standard and criteria developed in this study will help to prevent slip, trip, and fall injuries.

For low-power sensor networks, a compact design of advanced encryption standard (AES) algorithm is needed. A very small AES core for ZigBee devices that accelerates computation in AES algorithms is proposed in this paper. The proposed AES core requires only one S-Box, which plays a major role in the optimization. It consumes less power than other block-wide and folded architectures because it uses fewer logic gates. The results show that the proposed design significantly decreases power dissipation; however, the resulting increased clock cycles for 128-bit block data processing are reasonable for IEEE 802.15.4 standard throughputs.

Recently, Internet of Things (IoT) drives a large variety of research, development, and new type of markets. All type of devices and sensors will be part of the Internet of Things and will be able to communicate not only plain data, but also audio-visual, olfactory, and haptic media data. In addition, as the devices and sensors getting smarter, it is highly probable that they can process acquired media and metadata to extract higher level of information (e.g., semantics). To support such enhanced functionalities, ISO/IEC SC29 WG11 (MPEG) starts a new standard project, ISO/IEC 23093, called Internet of Media Things (IoMT) to provide standard data formats and APIs for media things. This paper presents the standardization activities of IoMT focusing on explaining terms, standard scopes, and major media things with their use cases. One of the use cases, an IoT system for a blind pedestrian navigation assistance, is evaluated to prove its effectiveness.

The auther studied the open-bite of Hellman dental age IIIC groups of Korean childern on the roentgenocephalometry. The subjects consisted of 45 males and 45 females with normal occlusion and acceptable profile. The major conclusions may be listed as follows: 1. This study was summerized in the form of tables, mean, standard deviation, minium and maximum for 35 angular, linear and ration measurements. 2. Charts of standard deviation from the mesurements were made for the clinical application.

The reduction of product development time is exposed to the competitive pressure due to shortened product-and production technology lifecycles as well as increasingly dynamic markets. Specially in automobile companies, that is of major importance for designing die because it is a bottleneck process in the development of a new car. To improve this conventional design process, this paper describes how to design it fast and flexibly. This was done by a modular method using standard template and a feature and knowledge based design method along the design process.
