ROK armed forces conducted exercise for something limited "Civil Factor" of Civil-Military Operations at the Liberalized Area in North Korea by using ROK battle simulation model and a linked US simulation model such as JNEM during ROK-US combined exercise period. However, they conducted exercise by exchanging with messages only during each exercise, because of hard coding for "Civil-Factor" and various situations applied onto battle simulation model and JNEM. Fortunately, ROK armed forces arranged the 5 functionalities of Civil-Military Operations which is adopted with military situation in Korean Peninsular. Even more "Civil-Military Operations Simulation Model System" is developing since 2014 by ROK MND. Among the 5 functionalities of Civil-Military Operations, the administration is fundamental. Its detailed operational plan is hard to be quantitative subjects because it is too qualitative to be simulated. But we found a way to quantify, and described simulation flow charts for the 5 main subjects (including 13 tasks) of administration to verify relevance between its simulation results and other functionalities. So we suggested a simulation method which gets an objective suitability, also hope this will be helpful to the Civil-Military Operations exercise.

The c-myc proto-oncogene is Involved In the control of normal cell proliferation and differentiation of many cell lineages. Although it has heen suggested that c-myc may play an important role in the mammalian early development, it Is unclear whether the embryonic c-myc mRNA is originated from zygotic gene expression or stored maternal message. Thus, we have construded expression vectors, In which the 5, flanking sequences including c-myc promoter region and a large non-coding exon I are fused 'sith E. coli lacZ gene that encedes $\beta$-galactosldase as a reporter. As c-myc exon I contains a modulatory sequence, we designed t, vo types of vectors (pcmyc.Gall and pcmyc-Ga12) to examine the role of exon I in c-myc expression. The former contains the complete exon I and the later has a deletion in 40 bp of modulator sequence located In the exon I of c-myc These vectors were microInjected into fertilized one-cell embryos and $\beta$-galactosidase activity was examined by X-gal staining during early embryogenesis. $\beta$-galactosidase activity derived from c-myc promoter was decreased at two-cell stage. The expression level directed by pcmyc- Ga12 was similar to that of pcmyc-Gal1, indicating that the medulatory sequence in exon I may not be Involved at least In the regulation of embryonic c-myc expression. In summary, the present study indicates that the c-myc promoter is functional at the early stage embryo, and the regulation of c-myc expression is under the control of "zygotic" clock of preimplantation mouse embryos.e embryos.

Turbo code, a kind of error correction coding technique, has been used in the field of digital mobile communication system. As the number of iterations increases, it can achieves remarkable BER performance over AWGN channel environment. However, if the number of iterations is increased in the several channel environments, any further iteration results in very little improvement, and requires much delay and computation in proportion to the number of iterations. To solve this problems, it is necessary to device an efficient criterion to stop the iteration process and prevent unnecessary delay and computation. In this paper, it proposes an efficient and simple criterion for stopping the iteration process in turbo decoding. By using sign changed ratio of extrinsic information values in turbo decoder, the proposed algorithm can largely reduce the average number of iterations without BER performance degradation. As a result of simulations, the average number of iterations is reduced by about $12.48%{\sim}22.22%$ compared to CE algorithm and about $20.43%{\sim}54.02%$ compared to SDR algorithm.

In this paper, we propose an efficient segmentation algerian using morphological grayscale reconstruction for region-based coding. Each segmentation stage consists of simplification, marker extraction and decision. The simplification removes unnecessary components to make an easier segmentation. The marker extraction finds the flat zones which are the seed points from the simplified image. The decision is to locate the contours of regions detected by the marker extraction. For the simplification, we use a new connected operator based on the size and contrast. In the marker extraction stage, the regions reconstructed to original values we excluded from the candidate marker. For the other regions, the regions which are larger than structuring elements or have higher contrast than a threshold value are selected as markers. For the initial segmentation, the conventional hierarchical watershed algorithm and the extracted markers are used. Finally in the region merging stage, we propose an efficient region merging algorithm which preserves a high quality in terms of the number of regions. At the same time, the pairs which have higher contrast than a threshold are excluded from the region merging stage. Experimental results show that the proposed marker extraction method produces a small number of markers, while maintaining high quality and that the proposed region merging algorithm achieves a good performance in terms of the image quality and the number of regions.

Two implementation methods for SOVA (Soft Output Viterbi Algorithm)of Turbo decoder are applied and verfied. The first method is the combination of a trace back (TB) logic for the survivor state and a double trace back logic for the weight value in two-step SOVA. This architecure of two-setp SOVA decoder allows important savings in area and high-speed processing compared with that of one-step SOVA decoding using register exchange (RE) or trace-back (TB) method. Second method is adjusting the reliability value with a scaling factor between 0.25 and 0.33 in order to compensate for the distortion for a rate 1/3 and 8-state SOVA decoder with a 256-bit frame size. The proposed schemes contributed to higher SNR performance by 2dB at the BER 10E-4 than that of SOVA decoder without a scaling factor. In order to verify the suggested schemes, the SOVA decoder is testd using Xillinx XCV 1000E FPGA, which runs at 33.6MHz of the maximum speed with 845 latencies and it features 175K gates in the case of 256-bit frame size.

This paper considers the consturction of 24/25 I-NRZI (Interleaved - Non Return to Zero Inverse) modulator designs for DVCR (Digital Video Cassette Recorder), and size of validity bit in order to store the amplitude value of square-wave and the standard data ( sine and cosine coefficients) at ROM Table that to acceptable the spectrum standard. The validity bit size of the standard data and the amplitude value of square-wave that to store at ROM Table are affected the size of pilot signal on the output spectrum, and the hardware size of modulator. At the designable 24/25 I-NRZI modulator, we simulated using random pattern (F0,F1,F2) that to verification the output data of the spectrum. Moreover, the resultant of the spectrum analysis, at the optimizing value, is 0.065 on the amplitude value of square-wave, and 3bit on the size of bit in order to store the standared data at ROM Table. In order to verify the hardware of designable 24/25 I-NRZI modulator, we perform to modeling of C-language firstly, and coding to Verilog HDL (Cadence Verilog XL) and synthesized using Synopsys (Library "Samsung KG75") tool as a base of spectrum results. In a foundation of this result, we are considered the size of hardware. In this paper, a considerable 24/25 I-NRZI modulator designable less than 10,000 gates as that is improved consturction as regards the path method of pre-coder etc, and able to application digital camcorders as now practical use.

This research is to understand young children ontologically by examining features of young children in the picture books for the early childhood. For the purpose, under the consultation with a picture book specialist and three level process of selection, 4 picture books were chosen as analytic objects. The study questions is as follows. What is ontological understandings on young children throughout picture books for the early childhood? Under this purpose the books chosen were John Burningham's , David Wiesner's , Hina Back's , Peter Sis's . The books went through dramaturgical coding and were thematised based on the theories of ontological phenomenology. Study results show that young child-being appearing in the picture-books are thematised as 'multi layered being with Ntwurf and Geworfenheit(Aldo)', 'responsible being risen above greed(Plotsam)', 'reflective being on face of others(Fairy of Jangsutang)', 'being who encourages educational response of adults.(Madlenka's Dog)' These results revealed that young child-being have features not different from (multi layered aspect of being), unique from(encouraging educational response), and beyond adult-being(responsibility and response towards others). Despite several limitations, this study helped understand the young children ontologically by revealing that they, not only as developmental beings with imperfection, dependence, and immaturity but as multi layered and requesting, responsible being, having the same features as adults and, at times, rise above adult-being.

There is no investigation has yet been conducted for ACOX1 and CSRP3 gene polymorphisms in Korean cattle (Hanwoo), and their associations with carcass and meat quality traits. In this study, SNPs in ACOX1 and CSRP3 genes were identified and their associations with carcass and meat quality traits were investigated in 227 Hanwoo animals. Two SNPs (g.224G> A and g.19491G>A) in ACOX1 gene and one SNP (g.14859C>T) in CSRP3 gene were identified in Hanwoo and sequence analysis indicated that these SNPs were located in the coding regions. The allele frequencies of ACOX1 g.224G>A and g.19491G>A SNPs were 0.57, 0.43, and 0.56 and 0.44, respectively, For CSRP3 g.14859C>T polymorphism, the C and T allele frequencies were 0.64 and 0.36, respectively. The Hanwoo cattle were used to detect PCR-RFLP patterns for estimating the allele frequencies. Single marker association analyses were performed between genotype of each SNP, and carcass and meat quality association traits to evaluate the relationships in Hanwoo. The g.224G>A SNP genotypes of ACOX1 gene, which was significantly associated with meat quantity grade at slaughter (P<0.03) and backfat thickness tended to be greater (P=0.06) in Hanwoo. The previously identified g.14859C>T SNP was used in this study and the obtained genotype and allele frequencies are almost similar with the previous results reported by Bhuiyan et al. (2007). However, no significant association was found between g.19491G>A SNP in the ACOX1 and g.14859C>T SNP genotypes of CSRP3 gene and considered carcass and meat quality traits. In conclusion, the information on the identified SNPs in CSRP3 and ACOX1 genes could be useful for further association study and haplotype analysis for the development of carcass and meat quality traits in Hanwoo.

The purpose of this study is to identify the adaptation experience of foster children. This qualitative research was conducted through in-depth interview of 8 foster children in and over 4th grade. In data analysis of this qualitative study, the grounded theory suggested by Strauss and Corbin(1998) was used. The raw data collected from in-depth interview with the participants were analyzed in open coding, through theoretically sensitive and constant comparisons method. As a result, total 11 categories, 30 subcategories and 96 concepts were generated. In summary, the casual condition that caused the core phenomenon was 'family stability collapse'. The core phenomenon that foster children experience during the process of adaptation was 'marginalization'. The contextual condition that affected the outcome was 'cultural shock' and 'loyalty conflict.' The intervening condition that promote or restrain the action/interaction on core phenomenon were, 'support system', 'resilience menifestation', 'negative predestination'. The action/interaction strategy on core phenomenon were 'will to power' and 'pursuing moral superiority'. As a result, two concepts, 'mechanical adaptation to foster care environment' and 'active formation' of foster care environment' were assumed.

This study investigated the problems of remarried wife with alcoholic problem. Specifically, this study regarded the wife's alcoholic problem as the problems of dysfunctional interaction among family members rather than an individual problem. The study had three purposes as follows. First, what were the interactions sustaining the conflict of remarried family? Second, what were the characteristics of remarried family relating to family conflict? Third, what were the interventions of family therapy to resolve the conflicts of remarried family? The total family counseling was 9 sessions, which included individual, couple, and family counseling. The study used constant comparative analysis by using open coding method to find the factors relating interactions sustaining the conflict of remarried family, the characteristics of remarried family relating to family conflict, and the interventions of family therapy to resolve the conflicts of remarried family. Also, the study used Miles and Huberman's matrix and graphical network display to show the interaction of family members. The study found intriguing factors, counteracting factors, relationship level, and relational elements to wife's alcoholic problems among family members. The study revealed husband's rigid family rules, husband's execution of patriarchal authority, husband's pursuit of family identity, and husband's emphasis of union among family members as the characteristics of remarried family. On the other hand, the study found the reinforcement of spousal subsystem, the pursuit of change in communication pattern between husband and wife, the amelioration of rigid family rules, and the acceptance of differences among family members as the intervention of family therapy to resolve the conflicts of remarried family.
