  • These days, ISIS terrorists have been expanding not only to european countries, but also to asian countries so South Korea is no longer safe from terrorists' attacks. Especially, 'soft target terrorism' makes many people maximizing fear of terrorism because it is caused by small groups - those who are armed with small arms and light weapons - and they are able to carry out hit and run attacks on civilian targets. It poses even more dangerous to kill massively. That is why November 2015 Paris attacks and January 2016 Jakarta attacks killed and injured many people because of 'soft target terrorism.' Therefore, the South Korea has also recognized the seriousness of terrorism by ISIS. The study has shown the precautionary measures about 'soft target terrorism' and how to defend against 'soft target terrorism' by looking through overseas examples. It is for the possibilities of 'soft terrorism' in South Korea because of the expansion of ISIS. As a result, 'soft target terrorism', caused by ISIS, could happen in South Korea. The counterplan is as in the following. First of all, 'soft target terrorism', which is collaborated with ISIS and domestic terrorists, could be caused by negative awareness of foreign residents and xenophobia so the public should change stereotypes about the foreign residents and there should be legislation about racial discrimination enacted by parliament and the government must practice the law. Second, the Korean anti-terrorism laws should be modified to minimize violations of human rights, related to the Korean citizens' personal information, and to stop the concentration of power into the hands of one law enforcement. Third, the government has to develop and to initiate the refuge&evacuation simulation, which prepares for 'soft target terrorism' and minimizes the damages if terrorists attack hot spots like central commercial areas or event halls.

  • Genetic polymorphisms due to variation in the number of tandem repeats of DNA sequences(VNTRs) provides a useful means for discrimination between individuals. Allele and genotype frequencies of the highly polymorphic Human Thyroid Peroxidase(TPO) gene were determined in Korean population samples by using PCR followed by polyacrylamide gel electrophoresis, a procedure called the amplified fragment length polymorphism(Amp-FLP) technique. In 123 unrelated Korean individuals 10 different alleles and 29 genotypes were observed. The TPO gene demonstrated a heterozygosity of 0.707 and the power of exclusion(POE) was 0.945. The probability of having the same DNA band within two unrelated individuals was 14.6$\times10^{-2}$. The distribution of observed genotypes conformed to Hardy-Weinberg equilibrium($x^2$=4.48, 0.05

  • The journal impact factor(JIF) of the Thomson Reuters(ISI) has been widely used to assess the impact of journal as well as its quality. However, the JIF contains its critical limitation, in which it does not measure the impact of journal but the average impact of articles in journal. Besides significant number of problems of the JIF has been noticed. Furthermore, given the limited coverage of domestic citation index database in comparison to those of international citation index, it is necessary to apply a more appropriate index with a high level of discriminating power. This study, therefore, aims to introduce some practical methods to measure the impact of domestic journals by using the Hirsch-type indices. As the Hirsch-type indices has been often used for overcoming the limitations of the JIF in worldwide, we hope that our research outcome offers an effective alternative to gauge the impact of journals more accurately. Consequently, using the variations of the h-index($h_s$-index, $f_s$-index) or the sum of issue level(issue based h-index, issue based f-index), we argue that it would improve the discrimination capacity of the Hirsch-type indices significantly and that we can measure the impact of domestic journals more clearly.

  • This study aims to discriminate differences in natural landscapes between the Cairngorms National Park in Scotland and the Jirisan National Park in Korea, using functions of content-based image retrieval such as texture, shape, and color. Digital photographs of each National Park were taken and selected. The low-level functions of photographic images were reduced to orthogonally rotated five factors. Based on the reduced factors, a linear decision boundary was obtained between Cairngorms landscapes and Jirisan landscapes. As a result, the discriminant function significantly delineated two groups, resulting in $x^2=63.40$ with df=5(p<0.001). Both the eigenvalue 2.417 and the value of wilks' lambda 0.29 supported that the most proportion of total variability came from the differences between the means of discriminant function of groups. It was estimated that four independent variables explained about 70.7% of total variance of dependent variable. The variable with the largest effect on landscapes was far region-related factor(r=1.07), followed by near region-related factor (r=0.90). A total of 90.7% of cross-validated grouped cases were correctly classified. It was interpreted that far distant regions, as well as near distant regions, had sufficient discrimination power for landscape classification between the Cairngorms National Park and the Jirisan National Park, so that landscape identity of the National Park over cultures was revealed by skylines in a most effective way. Relatively fewer factors making visual landscapes were effectively used to classify natural landscapes of the National Parks which had different semantics.

  • This study was conducted to analyze the genetic characteristics of Korean Native Pigs(KNP), and to establish an individual identification system comprising many microsatellite markers located on different pig autosomes. Genotype data from 13 microsatellites typed in 446 animals was used to determine the validation of a method of individual identification in 4 KNP. A total of 112 alleles of the 13 microsatellites were detected and average heterozygosities(polymorphic information content) ranged from 0.286(0.423) to 0.686(0.796) in this study. Comparing the pattern of allele frequency among the KNP, Yorkshire, Landrace and Duroc breeds, there was specific differentiation between populations at multi-allelic loci. The cumulative power of discrimination(CPD) was 99.999% by including 10 microsatellite loci for the individual identification system. The probability that two different individuals incidentally have same genotype was estimated to be $0.36{\times}10^{-9}$. The system employing these 10 markers therefore proved to be applicable to the individual identification of KNP.

  • A variety of customized marketing strategies are being implemented in the telecommunications market, including the offering of gifts to consumers, as competition in the market is being restructured with the focus on bundled products. However, the Korea Communications Commission (KCC) has recently imposed fines for user discrimination on telecommunication carriers whose marketing strategies have included the award of excessive prizes. In that regard, various issues related to the suitability and appropriate limit of the current gift regulation in the telecommunications market have been raised. Since the Fair Trade Commission, which had a similar scheme to that of the KCC, abolished the regulation on gifts in July 2016, disputes have arisen as to whether the current regulation on gifts is practically effective from the perspective of consumer benefit. In other words, discussions on the rationality of the theoretical and empirical grounds for the regulation on gifts only in the telecommunication market but not in other commodities markets have begun. As such, this study aims to empirically analyze the suitability of the current regulation on gifts in the domestic telecommunications market under the new competitive environment centered on bundled products, and to seek the rational improvement of, and infer the implications for, the regulation on gifts in the telecommunications market based on the results of the analysis.

  • Police officers have an obligation to their profession to continuously strive for fairness for all the people they serve. However, some police officers are believed to have developed prejudicial attitudes towards some groups of the society and exercised police power unfairly against them. Especially, when the actions of the police are prejudicial during criminal investigation, this can affect outcomes of the investigation. Therefore, the police need to tackle this problem effectively. In order to develop a preventive strategy, the police must have a clear understanding of prejudice. However, there has been little research on this topic in Korea. Thus, this study attempted to fill the gap. The purpose of the current study was to examine if prejudice of police officers are statistically valid. In order to answer this research question, the present study utilized the results of 173 polygraph examinations that had been employed to investigate traffic accidents in a provincial police agency in 2006. From the polygraph examination reports, information relating to the subjects could be identified and this information was analyzed, using a logistic regression. The results of the logistic regression revealed that most of the variables relating to the subjects did not affect the credibility of the subjects' statements. This means the police officers' belief that some groups of people make false statements more often than others during criminal investigation is an unfounded prejudice.

  • This research aims to find out what pre-service teachers are seriously concerned about and what they contemplated during the process of discovering the meanings of teaching, and to reveal the meanings compiled by the pre-service teachers. Furthermore, this research intends to identify the elements considered to help the pre-service teachers continue to construct the meanings of teaching in the education for pre-service daycare teachers by reviewing the process of contemplation. To do so, this study selected a target group of 29 seniors of M University who took the class of 'Teaching Method for Young children' given in the first semester of 2012 and 'Child Care and teaching Practice' given in the second semester of 2012. Research data collection was done based on the paper materials on participant observation, interview, student journals and professor feedbacks and small group discussion. According to the research, the pre-service teachers created the meanings of teaching as they experience confusion between one extreme to another of power and looking easy, having children focused and being focused, just giving and leaving and discrimination and equality. They considered teaching as a process of continuous reconstruction by choosing the best place between the opposites within the context of teaching and understood that teaching is to respect the right of learning for children and at the same time to make efforts to develop inner-self. In addition, to support the pre-service daycare teachers in their efforts to find the nature of teaching in the education program, it is required to review the teaching process from a variety of aspects in the atmosphere where they are not afraid of confusion, and to provide time to meditate alone and share ideas with others.

  • Alcoholism affects not only the individuals who depend on it, but also their families. Children who have an alcohol dependent parent have various problems and need help, but little attention has been given to them. Many references report only negative characteristics of these children. In order to help the children of alcohol dependent parents, health professionals need more information. A wholistic understanding and analysis of these children is needed as a basis for the development of suitable programs of help them. A phenomenological methodology was used to identify the experience of children whose fathers were addicted to alcohol. The findings portray the essence of the lived experience of children of alcohol dependent fathers. Nine adolescents participated in in-depth inverviews and observation with the researcher, done between October and December 2001. The data were recorded on audio tape and transcribed. Sampling was continued until the data were theorectically saturated. The Colaizzi's method was used for data analysis. The results of this study are as follows. Three themes and twenty six meanings were identified. The first theme is Living Alone: living abusively as partner to an alcohol dependent father, living dangerously like an explosive fury, living as an object that ha no self, living with rejection of fatherly being, living with felt responsibility but having no power to help mother who suffers patiently with pain and abuse, living along with no shoulder to lean on, and living with the prejudice of sex discrimination. The second theme is Paradoxical Coping in Life. The meanings are obsessive behavior as a way to control father's behavior, always on the defensive due to anxiety and tension, being afraid of life alone due to paranoid thoughts, contradictory expectation about father's drinking behavior due to life with chronic tension, stress becoming familiar and life being boring and tendious without stimulation, life that is fake and filled with misinterpretations about reality, affection sought from others due to loneliness, compensatory life within peer group, negative expectation about the future due to negative experiences, controling others to protect ego, denial of real emotion to protect self from hurt, life of regretting self, and strong need for approval from others. The third theme is sustaining life. The meanings are ambivalence between revenge on father and pity, struggle for desirable self against fear of gather-like image, understanding father through self reflection, hope to find fatherly being through father's recovery, being able to stand through emotional control and cognitive restructuring, nurturing the seed of hope for the future while in a situation of desperation. The contribution of this study is to give a wholistic understanding of the empirical reality of children of alcohol dependent parents and to develop substantive theory in nursing knowledge. In nursing practice, the results of this study can provide a foundation for the development of programs for children of alcohol dependent parents.

  • This study was conducted to establish the individual identification system and to estimate the genetic characteristic of Jeju native horse (JNH) using 13 microsatellite markers located on different horse autosomes. The markers were genotyped on 191 animals from five horse breeds including Jeju native horse (JNH). In total, 138 alleles were detected from the genotypes of 13 microsatellite markers. The average heterozygosities ranged from 0.317 to 0.902 and the polymorphic information content (PIC) ranged from 0.498 to 0.799 in JNH. We found that there were significant differences in allele frequencies in JNH when compared with other horse breeds. In ATH4 marker, there were specific allele frequence pattern that some of allele only found in JNH, Mongolian horse (MONG) and Jeju racing horse (JRH). The calculated cumulative power of discrimination (CPD) was 99.9% when nine microsatellite loci were used for analysis in the individual identification system. Also, the matching probability that two unrelated animals would show the same genotypes, was estimated to be $0.60{\times}10^{-10}$. Therefore, in the nine markers used in this study can be used for individual identification in the Jeju native horse population.
