This research aims analyze the current situation and problems of cultural heritage education, and propose the methodology of cultural heritage education and the model of the curriculum for each education subject. This study consists of three parts. First, the current status of education related to cultural heritage was examined separately by general public, university and graduate students, and practitioners. Second, we reviewed the National Competency Standard(NCS) and the UNESCO World Heritage Competency Framework(CF) as a way to solve the problem of cultural heritage education for each education subject. By examining the methodology and curriculum model of cultural heritage education, we tried to find the future direction of cultural heritage education. Third, the education model of the cultural heritage curriculum for each educational subject was proposed by reflecting the direction and the cyclical education model of sustainable cultural heritage education. In future studies, we intend to use the education model presented in this study to specifically propose basic guidelines for the cultural heritage convergence curriculum.

The modeling of a product data is becomming more and more important in engineering environment, especially for the development of CAD/CAM system as a basis of computer integrated manufacturing system. Model is a formalized representation of the real world, and modeling is the task to identify, abstract, and formalize the product information into an unambiguous representation. In this study, the piping system, one of typical product of ship outfitting system, is modeled. The STEP idea is followed to provide a common mechanism to represent the product information throughout the life-cycle, and the object oriented paradigm is used in the analysis and design of the model. The definitions given within this model are independent of the specific application domain so that the same methodology can be used for other purpose.

This paper reports the study on development and verification of numerical models and analyzes of flow at high speed around structural elements in the shape of a curved pipe (e.g., a fragment of a water slide). Possibility of engineering estimation of wind forces acting on an object in the shape of a helix is presented, using relationships concerning toroidal and cylindrical elements. Determination of useful engineering parameters (such as aerodynamic forces, pressure distribution, and air velocity field) is presented, impossible to obtain from the existing standard EN 1991-1-4 (the so-called wind standard). For this purpose, flow at high speed around a torus and helix, arranged both near planar surface and high above it, was analyzed. Analyzes begin with the flow around a cylinder. This is the simplest object with a circular cross-section and at the same time the most studied in the literature. Based on this model, more complex models are analyzed: first in the shape of half of a torus, next in the shape of a helix.

This paper describes the methodology of an IEC 1131-3-based control logic generator for the control system design and converting algorithm between programmable languages. The proposed control logic generator is generated based on the software model and common element with data type, variables, POUs(program organization unit) and execution control unit commonly used within programmable languages of IEC 1131-3 Standard. The generation method of object file was proposed on five programmable language based on IECI 131-3. The generation method of object file is represented as following; 1) the generation method using conversion algorithm from LD to IL with FBD(function block diagram), 2) the generation method using C code generation algorithm from SFC using the SFC execution sequence with FBD and ST(structured text). The proposed control logic generator was implemented by Visual C++ and MFC on MS-windows NT 4.0

This study analyzed the process of development and verification of standards through the competency analysis of fashion accessories products in the development of 'National Competency Standards'(NCS), which was carried out in 2013 for the fashion industry. The NCS for fashion accessories production was developed through three Focus Group Interviews (FGIs) and fashion accessories production was defined as "the process of design, development and manufacture intended to produce items that improve the degree of completion of fashion products that are produced from textile fabric, knitted fabric, leather and other materials such as bags, belts, hats, gloves, scarves, neckties and socks with the exception of clothes". The competency unit for fashion accessories production was analyzed in 11 categories: development of design; development of materials; production of prototype samples; calculation of cost; determination of mass production model and price; planning of main manufacture process; ordering of materials; planning for mass production; preparation for mass production; mass production; and inspection of completed products, and the verification was carried out on development outcomes through a survey carried out of on-site personnel. This study recommends the following direction for future improvements based on an analysis of the development process of the NCS for fashion accessories production. First, future development of standards should first provide a rational category system for each area of fashion good production based on the production process, which should be followed by a detailed competency survey. Second, in order to ensure a more efficient verification survey, an expert for each competency unit should be designated for the develop standard to induce a more sincere response. Also the questionnaire should require supplementation in order to collect the various additional opinions of experts of the field. Finally, this study concludes that it is urgent to procure an education infrastructure and specialized professors in order to apply the competency standard for fashion accessories production to the education sector. This study also concludes that the government will be required to provide systematic and consistent support aimed at supplementing development and forming a firm collaborative working environment for the industry and academia in order to improve the current education environment and build a more field-oriented education environment.

Purpose : It is now understood that blood pressure (BP) measurement in the routine pediatric examination is very important because of the relevance of childhood BP to pediatric health care and the development of adult essential hypertension. There hasn't been a reference table of BP for Korean children and adolescents up to now. This study was to make normative BP references and to provide criteria of hypertension for Korean children and adolescents. Methods : BP measurements were done on 57,433 Koean children and adolescents (male: 29,443, female: 27,990), aged 7 to 20 years, in 2005. Heights and weights were measured simultaneously. Oscillometric devices, Dinamap Procare 200 (GE Inc., Milwaukee, Wi, USA), were used for the measurements. BPs were measured 2 times and mean levels were gathered for the analysis. Outliers of 2,373 subjects with overweight per height, over ＋3SD, were excluded for the analysis. For the BP centiles adjusted by sex, age and height, fixed modified LMS method which was adopted from the mixed effect model of 2004 Task Force in NHLBI (USA) was used. Results : Normative BP tables for Korean children and adolescents adjusted for height percentiles (5th, 10th, 25th, 50th, 75th, 90th, 95th), gender (male, female) and age(7 to 18 years) were completed. Height centiles of Korean children and adolescents are available from Korean Center for Disease Control and Prevention homepage, http://www.cdc.go.kr/webcdc/. Criteria of hypertension (95th, 99th percentile) and normal range of BP (50th, 90th) adjusted for height percentiles, age and gender were made. Conclusion : This is the first study to make normative BP tables and define hypertension for the Korean children and adolescents. Reliability and accuracy of Dinamap Procare 200 oscillometer for BP measurements remains debatable.

Dental hygiene was originated from dentistry and dental hygiene knowledge was a component of dental knowledge body. Since the late 1980s dental hygiene theory was began to develop. Nursing theories such as metaparadigm, nursing process and human need theory affected theory development as dental hygiene process. Dental hygiene process provides a framework for high quality dental hygiene care. Dental hygiene process include five phases; assessment, dental hygiene diagnosis, dental hygiene planning, implementation, evaluation. Dental hygiene process of care is recognized as standard for dental hygiene education and clinical dental hygiene practice. Dental hygiene practice has moved from auxiliary model to professional model. Critical thinking skill and disposition are necessary to provide evidence-based dental hygiene care using dental hygiene process as clinical process and critical thinking process. Critical thinking, problem solving and evidence-based practice must be integrated into dental hygiene process for quality dental hygiene care.

Wireless Body Area Networks (WBANs) are becoming increasingly important to solve the issue of health care. IEEE 802.15.6 is a wireless communication standard for WBANs, aiming to provide a real-time and continuous monitoring. In this paper, we present our development of a modified Markov Chain model and a backoff model, in which most features such as user priorities, contention windows, modulation and coding schemes (MCSs), and frozen states are taken into account. Then we calculate the normalized throughput and average access delay of IEEE 802.15.6 networks under saturation and ideal channel conditions. We make an evaluation of network performances by comparing with IEEE 802.15.4 and the results validate that IEEE 802.15.6 networks can provide high quality of service (QoS) for nodes with high priorities.
