The purposes of this study are 1)to analyze a needs of re-education & continuous education for R&D human resources 2)to systemize the existing education program and 3)to provide useful implications to help the politics for re-education & continuous education for R&D human resources. The survey to R&D human resources in universities, government-supported research institutes and industries was conducted for analyzing the needs of R&D human resources for the existing education programs through investigation for the current state and importance & satisfaction level for the existing program. For proposing the effective education program, the barrier and improvement factors of re-education program were examined as well. In addition, the needs for the government support policies for re-education program were also analyzed.

The aims of this study is to analysis the effects of obese management program for obese young adults. Nineteen studies were included for meta-analysis and SIGN was used for quality assessment. Effect size was analyzed by CMA 3.0 and Revman 5.4. Overall effect size on obese program was big (d=-0.91) and high heterogeneity (I²=81%). BMI (d=-0.83) and body fat (d=-0.93) shown the big effect size and TG (d=-0.76) and LDL (d=-0.59) were medium effect size among the studies that used dependent variables. Intervention with aerobic and combination exercise, middle and high exercise intensity, over 1 hour exercise were effective. Based on current findings, obesity management programs have significant effects for young adults.

This study set out from the perception that one should develop and activate differentiated programs from those 5 programs of the Health Family Support Center (family counseling program, family education support project, family affinity culture support project, care support project, diversity family support project) on the subjects (n=299) of residents in G metropolitan city by reflecting the levels of family values, communication between family members and family relationship. To achieve the study purposes above, this study devised research questions as follows: Research question 1. What are the levels of local residents for their family values, communication between family members and family relationship? Research question 2. Is there any difference in demanding family support project programs according to the local residents' family values, communication between family members and family relationship? Following are the results of this study: First, the levels were analyzed to be more than the average (on a maximum scale of 5 points) with local residents' family values (M=3.55, S.D.=.664), communication between family members (M=3.65, S.D.=.669), family relationship (M=3.69 S.D=.584) Second, the necessity levels for family values, communication between family members and family relationship of the group below the average as compared with the group over the average was found to be significantly high in family education support project, family affinity culture support project, care support project and diversity family support project except family counseling program. Accordingly, strategic plans for increasing the participation rate for the programs by the Health Family Support Center and activating those programs could be by investigating in advance the levels of family values, communication between family members and family relationship by each program respectively and differentiating the target level for the program by the group, or by giving preference to the group below the average who have high needs of program necessity when making decisions for the participation preference of the programs.

In this paper, the retention characteristics of 3D NAND flash memory applied with tapering and ferroelectric (HfO₂) structure were analyzed after programming operation. Electrons trapped in nitride are affected by lateral charge migration over time. It was confirmed that more lateral charge migration occurred in the channel thickened by tapering of the trapped electrons. In addition, the Oxide-Nitride-Ferroelectric (ONF) structure has better lateral charge migration due to polarization, so the change in threshold voltage (V_th) is reduced compared to the Oxide-Nitride-Oxide (ONO) structure.

A volcano disaster damage prediction system supports decision making for counteracting volcanic disasters by simulating meteorological condition and volcanic eruptions. In this system, a program called Fall3D generates predicted results for the diffusion of ash after a volcanic eruption on the basis of meteorological information. The relevant meteorological information is generated by a weather numerical prediction model known as Weather Research & Forecasting (WRF). In order to reduce the entire processing time without modifying these two simulation programs, pipelining can be used by partly executing Fall3D whenever the hourly (partial) results of WRF are generated. To reduce the processing time, successor programs such as Fall3D require that certain features be suspended until the part of the results that is based on prior calculation is generated by a predecessor. Even though Fall3D does not have a suspend or resume feature, pipelining effect can be produced by using the program's restart feature, which resumes simulation from the previous session. In this study, we suggest a workflow that can control the execution type.

Flywheel energy storage system (FESS) is defined as a high speed rotating flywheel system that can save surplus electric power. The FESS is proposed as an efficient energy storage system because it can accumulate a large amount of energy when it is operated at a high rotating speed and no mechanical problems are encountered. The FESS consists of a shaft, flywheel, motor/generator, bearings, and case. It is difficult to simulate rotor dynamics using common structure simulation programs because these programs are based on the 3D model and complex input rotating conditions. Therefore, in this paper, a program for the FESS based on the 2D FEM was developed. The 2D FEM can model easier than 3D, and it can present the multi-layer rotor with different material each other. Stiffness changing of the shaft caused by shrink fitting of the hub can be inputted to get clear solving results. The results obtained using the program were compared with those obtained using the common programs to determine any errors.
