Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

위기 유가족을 위한 단기 집단상담 프로그램 개발

본 연구는 재해 및 위기상황이 발생한 후 이로 인해 가까운 사람을 잃은 유가족들을 위한 단기 집단상담의 한 모형을 개발제시한 것이다. 기존에 나와 있는 위기상담 프로그램들을 비교하였고 이를 기반으로 인지행동치료적 접근에서 이들이 자신의 삶을 좀 더 효과적으로 통제할 수 있는 프로그램을 개발하고자 하였다. 지금까지의 재해 및 위기상황을 주제로 하는 우리나라의 논문들을 고찰해본 결과 의료적, 물질적, 재정적 지원체계는 어느 정도 갖춰져 있으나 심리적, 정서적 지원체계는 거의 없는 실정이다. 최근 발생한 대구지하철참사의 경우만 보더라도 이에 대처하는 위기상황 극복 노력이 거의 기존의 지원체계에 의존하고 있는 실정이며, 일부 심리상담 자원봉사가 시도되기는 했으나 전문가와 전문프로그램의 부재 등으로 인해 그 실효성이 대우 미미한 실정 이다. 본 연구 결과는 위기 유가족들의 스트레스 대처능력을 강조하며, 적응적 대처전략의 습득에 대한 구체적인 지침을 제공해 줄 것이다. 위기 유가족들은 스트레스 상황에 대한 부정적 지각을 통해 자신의 우울, 불안, 분노감을 더욱 증대시키는 경향이 있다. 따라서, 위기 유가족들이 효과적이고 적응적인 대처전략을 습득할 수 있다면, 이는 사회적 지원 체계와 결합되어 그들의 역기능적인 증상 유발을 감소시키는 데 크게 기여할 것이다. This study aims to develop a brief group intervention program for the families which have lost their member(s) through a calamity. In particular, it is through various comparisons with the former intervention programs that we have developed the program in terms of cognitive-behavioral therapy, which can help the families get more sufficient control of their own lives. Considering the papers concerning crisis intervention programs that have been published so far, the focus of major programs lies on the medical, material, and financial supports without mention of psychological and emotional ones. For example, in case of recent subway conflagration in Daegu, every effort was made to support those involved in the calamity only in terms of the former support system. Any professional psychological and emotional intervention was not provided for the families who suffered from the accident. This study may contribute to increasing the abilities for such families to overcome the critical experience and it may help them to learn sufficient coping strategies with various stress situations. The negative effect of critical events leads to the paychological symptoms such as depression, anxiety, and rage and so on. Therefore, the efficient psychological intervention program will be very helpful and necessary to overcome the crisis experiences that those exposed to various calamities face.

The content's authentication is very important in the field of Digital Multimedia Contents which is based on the Internet. There are several methods to perform the authentication. The Watermarking is the one of those methods. This paper's every process is based on the image application. The proposed watermarking method has the 3-State information and performs the embedding and the detection without reference Content. when we authenticate the Owner Information, it uses correlation function. The special feature is embedding the watermark depends on the original contents and using the DWT(Discrete Wavelet Transform) Domain when it is applying the SS(Spread Spectrum) method. therefore, certain extra probability of error will be reduced. and DWT is more faster than other transform method(DFT, DCT etc). When we use N size image, the computation can reduce from O(N·logN). and we can hide some more information per bit. In this experiment, We used some general signal processing (such as Noise Addition, Compression, Scaling etc.) as the Attacks.

The purpose of this study is to present quantitatively the influence of variables that had the largest effect on the changes in suspended solids(SS), which would cause turbid water phenomenon, among water quality factors of the non-point pollution source, and then to develop a multiple regression equation of SS and predict the water quality of ungaged watersheds so as to provide basic data to establish efficient management plans for SS which flow in rivers and lakes. To identify the correlation of SS with the amount of rainfall and the state of land use, a simple correlation analysis and a simple regression analysis were conducted respectively, Finally, a multiple regression analysis was conducted to provide that SS were set as dependent variables while the amount of rainfall, paddy fields and dry fields were set as independent variables. As a result, the amount of rainfall had the most significant influence on changes in SS, followed by dry fields and paddy fields. In addition, the multiple regression equation was developed to predict SS in unmeasurable watersheds.

The organic electroluminescent devices based on small molecules or conjugated polymers have been greater interest due to their possible applications for flat panel displays. They are attractive because of the capability of multicolor emission, low operating voltage, low power consumption, and competitive cost. The high mobilities allow larger current densities to be reached under operation in the space charge limited conduction region, hence facilitate access to higher luminance as required for passive matrix devices. In this study, we have investigated the molecular orientation control effect of organic electroluminscent devices. We aligned the p-sexiphenyl, which is a blue emitting material, using simple rubbing treatment. We obtained the anisotropic optical propery by UV/visible absorption measurement. In the current density-voltage relationship, we observed that the current density of the rubbing treated devices is larger than that of the non-rubbed device. This indicates that there is a more efficient carrier injection from the anode in the rubbed p-sexiphenyl devices.
