Objectives: The purpose of this study was to evaluate the customized oral health promotion program for North Korean defectors (NKDs). Methods: Using a pre-survey comprising phases 1-5 of the PRECEDE-PROCEED model, a customized oral health promotion program was created. The participants, a total of 129 NKDs, were allocated to the experimental group (n=64; 43 females and 21 males) or the control group (n=65; 46 females and 19 males). After the interventions, phases 7 to 9 of the PRECEDE-PROCEED model were executed to determine the effect of the program. Results: The results for phase 7 revealed high satisfaction with the program, with an average of 2.89 out of 3 points. In phase 8, concerning the impact evaluation, it was found that oral health beliefs and oral health knowledge were improved, with statistically significance differences before and after the experiment. Phase 9, concerning the outcome evaluation, showed that there were statistically significant differences in the average within groups before and after education in oral health beliefs (OHB), O'Leary index scores, and CPI. In terms of the difference between the groups, there were statistically significant improvement in OHB, O'Leary index scores, and CPI after the education program. Conclusions: The oral health promotion program developed in this study has made a positive contribution to improve the oral health status of NKDs.

A genetic improvement program in Korea was implemented to improve the performance of Hanwoo cattle by generating livestock with genetically desirable economic characteristics. In particular, in response to external changes, such as the expansion of Free Trade Agreement (FTA), the livestock genetic improvement program has increased farm income by improving the productivity and quality of Hanwoo cattle. Using production cost data from Statistics Korea, the total input and output indices of Hanwoo feeding cattle from 2008 - 2021 were estimated and the growth and productivity changes were analyzed. The productivity change measures results were used to estimate the cumulative effects of the Hanwoo genetic improvement program on quality improvement, another purpose of the program, using a finite distributed lag model. The average annual increase in output (market weight) of Hanwoo was 0.9%. However, total input increased by 1.6%, resulting in a 0.6% decline in total factor productivity. In contrast, the Hanwoo genetic improvement program contributed significantly to the production of high quality beef, rather than contributing to improved productivity of the cattle. Hanwoo carcass weight, which is used as a performance indicator for the livestock genetic improvement program, has significantly improved and is projected to increase at a slower rate. The collective findings indicate the need for new performance indicators that can comprehensively indicate the performance of the genetic improvement of Hanwoo.

The modeling of combustion process is an important part in an engine simulation program. In this study, calculated results using a conventional B-K model and the other model which is called GESIM were compared with experimentally measured data of a three-cylinder spark-ignition engine under wide range of operating conditions. The burn rates calculated from the combustion models were compared with the burn rate calculated from the one-zone heat release analysis that uses measured pressure data as an input data. As a result of the two models' comparison, the GESIM combustion model conformed to be closer to the data acquired from the experiment in wide operating ranges. The GESIM model has been improved by introducing a variable that considers the flame size, the area of flame conacting the piston surface into the model, based on the comparison between the experimental result and the calculated results. The improved combustion model predicts experimental results more precisely than that of GESIM combustion model.

This study was designed to analyze the present condition of the lifelong education field training program and to implement the need assessment of field training program based on the job model application. In order to achieve these goals, surveys were conducted through questionnaires and in-depth interviews targeting staffs of lifelong education institution in Busan area. The 115 subjects were analyzed by frequency distribution, the paired samples t-test, and the Borich's need analysis. The result showed that the field training program was poorly executed during the year of 2013 due to deficiency of certified practitioners and systematic guidelines. Also, the most highly demanded tasks were promoting change, networking, planning, developing programs and conducting surveys among various roles of lifelong educators. On the other hand, the need for the assisting and supporting programs were relatively low. Finally, this study concluded the need for developing systematic guidelines and for accrediting as a lifelong education field training institution nationwide. The results of this study would ultimately contribute to enhance the quality of lifelong education field training program.

This paper is to model a 3D-shape product applying mathematically the data acquired from a 30 scanner and using an Automatic Design Program. The research studied in th reverse engineering up to now has been developed continuously and surprisingly. However, forming 3D-shape sol id models in CAE and CAM. based on the research, the study leaves much to be desired. Especially, analyses and studies reverse-designing automatically using measured data after manufacturing. Consequently, we are going to acquire geometric data using an 30 scanner in this study with which we will open a new field of reverse engineering by a program which can design a 3D-shape solid model in a CDA-based program automatically. Utilization of this program make it possible to minimize time in designing a product and establish a ADS(Automatic design system) program library to using all of the data from reverse engineering.

This paper aims at developing a finite element program to predict undrained behavior of granular soil by using elasto-plastic constitutive model. A computer program developed by authors based on Christian's techniques for undrained behaviour of the soil has been employed coupled with Lade's single work-hardening model. Modification of the program for drained behaviour, considering restraint of volumetric strain, makes it possible to analize the underained behaviour. To validate the newly developed program, comparison of results was performed between numerical values and experimental data for Baekma river sand as well as Sacrmento river sand studied by Seed and Lee. The program is evaluated to have high accuracy.

As the importance of technology increases, so too does its use in various areas. In education, technology is often used. However, due to teachers' lack of knowledge about technology, they often remain at the level of simple utilization, without applying it to learning. Thus, there is a growing need for Technological Pedagogical Content Knowledge (TPACK), which enables teachers to have knowledge about technology and use it appropriately given the content. Although TPACK studies are underway in many subjects, they suffer from the limited functionality of the included technology. To solve this problem, in this study, the range of technology in TPACK was extended to programming, and a TPACK-P model was developed to teach this expanded TPACK to pre-service teachers. To verify the effectiveness of this model, the TPACK-P training program developed during the 15th classes was applied to 19 pre-service teachers. We used Park and Kang (2014) as a tool to measure these teachers' TPACK before and after treatment to observe any changes. The results showed that the TPACK-P education program showed statistically significant improvement in all areas except Pedagogical Content Knowledge(PCK). Compared with the ICT-based TPACK training program, which was administered to a control group, the TPACK-P training program proved to be more effective in the development of Technological Pedagogical Knowledge(TPK) and TPACK among pre-service teachers.
