  • This paper presents a parameterized simulation program with integrated circuit emphasis (SPICE) model of a two-level microbolometer based on negative-temperature-coefficient thin films, such as vanadium oxide or amorphous silicon. The proposed modeling begins from the electric-thermal analogy and is realized on the SPICE modeling environment. The model consists of parametric components whose parameters are material properties and physical dimensions, and can be used for the fast design study, as well as for the co-design with the readout integrated circuit. The developed model was verified by comparing the obtained results with those from finite element method simulations for three design cases. The thermal conductance and the thermal capacity, key performance parameters of a microbolometer, showed the average difference of only 4.77% and 8.65%, respectively.

  • In this paper, I present the design of Operational Flight Programs(OFPs) on a Multi-Core based Mission Computer(MC) for the optimized performance of the OFPs on Multi-Core based MC. The program assigned as tasks on Multi-Core environment can be scheduled by designing with the use of OpenMp, which is the standard for parallel programming. This paper also describes the differences between Multi-Core Program(MCP) on the technique and Single-Core Program(SCP) in terms of performance aspect. The new proposed design technique is applied to the Integrated Up-Front Control OFP(IUFC OFP) on General Processor Module where Multi-Core based. This paper describes the Multi-Core design technique for the optimized performance of the IUFC OFP, which display and control flight data(Navigation, Communication, Identification Friend or Foe) to pilot.

  • The goal of this study is to assess the spatial distribution of natural slopes and cutting slopes under would-be development. For this goal, a quantitative slope stability analysis method using GIS integrated with a computer program was developed. Through field investigations, the discontinuity parameters were collected such as orientation of discontinuity, persistence, spacing, JRC, JCS, and water depth. The distributions were interpolated from the ordinary kriging method in ARC/INFO GIS after variogram analysis. The layers showing all parameters needed for limit equilibrium analysis were constructed. The final layer using GIS works composed of 162,352 polygons, that is, unit slopes. The rock slope stability analysis program was coded by C++ language. This program can calculate geometrical vectors related to rock block failures using input orientation data and direction and dimension of strength to occur failure. Also, this can calculate shear strength of joints through empirical equations and quantitative factors of safety. This methodology was applied to the study area which is located in Jaecheon city and Danyang-gun of the northeastern Keumsu is about 135$km^2$. As a result, the study area was entirely stable but unstable, that is, factor of safety less than 1.0dominantly at the slopes near Keumsil, Daejangri, Keumsungmyun and Sojugol, Mt. Dongsan, Juksongmyun by the natural slope stability analysis. Assuming the cutting slope showing the same direction immediate, and quantitative analysis of factors of safety for a regional area could be conducted through GIS integrated with a computer program of limit equilibrium.

  • This study examined the effect of visual art appreciation integrated with expression(integrated art appreciation) upon young children's drawing expression. The pretest-posttest control group design was chosen for the study. Twenty kindergarten children assigned to the experimental group were exposed to a program of integrated appreciation activity for 10 sessions. Another group of 20 kindergarten children were assigned to the control group taught by the traditional art teaching methods. Analysis of Covariance was applied for data analysis. Children in the experimental group showed higher scores in such drawing expressions as line, color, shape, composition, and theme.

The program, including individual art therapy, group life skills programs, culture experiences, individual counseling programs and regular network meetings between parents and teachers were carried out to children with ADHD tendencies in order to build environmental support systems. As results, the psychological and emotional behaviors of children with ADHD tendencies have changed. This study, also, was able to verify the possibility of positive changes for the children with ADHD. Based on these results, the practical guidelines for building the support systems of children with ADHD tendencies were suggested.

  • The free-living photoheterotrophic Gram-negative bacterium Rhodobacter sphaeroides possesses a quorum-sensing (QS) regulatory system mediated by CerR-CerI, a member of the LuxR-LuxI family. To identify the genes affected by the regulatory system, random lacZ fusions were generated in the genome of R. sphaeroides strain 2.4.1 using a promoter-trapping vector, pSG2. About 20,000 clones were screened and 23 showed a significantly different level of ${\beta}$-gal activities upon the addition of synthetic 7,8-cis-N-tetradecenoyl-homoserine lactone (RAI). Among these 23 clones, the clone showing the highest level of induction was selected for further study, where about a ten-fold increase of ${\beta}$-gal activity was exhibited in the presence of RAI and induction was shown to be required for cerR. In this clone, the lacZ reporter was inserted in a putative gene that exhibited a low homology with catD. A genetic analysis showed that the expression of the catD homolog was initiated from a promoter of another gene present upstream of the catD. This upstream gene showed a strong homology with luxR and hence was named qsrR (quorum-sensing regulation regulator). A comparison of the total protein expression profiles for the wild-type cells and qsrR-null mutant cells using two-dimensional gel electrophoresis and a MALDI-TOF analysis allowed the identification of sets of genes modulated by the luxR homolog.

  • As a basic study for the development of pilot-scale distillation process of waste photoresist strippers from semiconductor industry, lab-scale experiments for the recovery of NMP (N-methy1-pyrrolidione) and BDG (Butyldiglycol) from waste photoresist strippers have been made using a spinning band vacuum distillation column. Purities of NMP and BDG obtained from the present experiments were higher than 99.5%. Furthermore, water content was less than 1000 ppm, color grade(APHA) less than 50, most metal contents except sodium less than 1 ppb. Those results indicate that NMP and BDG reclamed by distillation satisfy the their specifications required for the formulation of new photoresist strippers. Recovery rate of NMP and BDG was 96 and 53%, respectively, for type A, and 93 and 57%, respectively, for type B waste PR stripper solution.

  • This study was conducted to identify nutrition knowledge, eating behaviors, and the need for an integrated program to improve eating behaviors according to residential type of female college students. Data were collected from March 16 to April 16, 2021, using online self-report questionnaires and the final 217 data were used. To analyze data, frequencies and percentages, means and standard deviations, independent sample t-test, and ANOVA were conducted using SPSS WIN 26.0. The results showed that home residents had better eating behaviors than those living in rented rooms. Moreover, the demand for an integrated eating behavior improvement program for disease and health information topic was higher among home residents and participants in rented rooms than among those living in dormitories. When developing an integrated program for improving eating behaviors among female college students, it is essential to apply a differentiated intervention program that considers residential type.
