  • We identify the correct chromosome and locate the corresponding markers close to the QTL in the linkage analysis of a quantitative trait by using the SSVS method. We consider several markers linked to the QTL, as well as to each oyher and thus the i.b.d. values at these loci generate collinear predictors to be evaluated when using the SSVS approach. The results on considering only closely linked markers to two QTL simultaneously showed clear evidence in favor of the closest marker to the QTL considered over other markers. The results of the analysis of collinear markers with SSVS showeed high concordance to those obtained using traditional multiple regression. We conclude based on this simulation study that the SSVS is quite useful to identify linkage with multiple linked markers simultaneously for a complex quantitative trait.

  • This essay would focus on a kinds of new archival strategy. The main frame has been the kinds of activities regulated by laws, or formal activities since 1999. In the case of presidential archives has no another frame. There had never kinds of presidential archives system until President Noh, if anything. It means that the frame has some important points. Although it is, we have to say about the limits of the frame. This essay show 'metaphor frame' for archival system. I think that we have to guess there are methodologies below the two frames. One is quantitative study methodology, and another is qualitative research methodology. The later focuses on the experiences for making narratives. We have to know that this methodology is out of fashioned in the field of history department and cultural anthropology department for the purpose of alternative studies. This essay says about 'archival field description' and 'narrative records' for the new records in archival field. I have to say about that we needs to discuss about kinds of new archival discours. And to conclude, we should manage the records in culture.

  • The purpose of this study examined the feasibility and efficacy of a senior center-based diabetes self-management program applying action research approach. The cyclical action research method was applied for this study: plan, act, evaluate, and reflect in delivering three waves of the intervention program. Three waves of a 12 weeks-length small group diabetes self-management program were offered during the period of 15 months in a senior center in Seoul. Planning of $2^{nd}$ and $3^{rd}$ wave program were based on reflection of $1^{st}$ and $2^{nd}$ program evaluation respectively. Among the 46 participants, 93.48% (N=43) completed the program. The quantitative evaluation showed statistically significant improvement in HbA1C(p<.001), fasting plasma glucose(p<.001), BMI(p=.016), waist circumference(p=.001), systolic blood pressure(p=.036), diabetes self-management behavior(p<.001) and health knowledge(p=.008). Qualitative data revealed that individual management was very helpful in empowering and adhering for own diabetes care for the participants. Participants reported high satisfaction towards the program with mean satisfaction score of 65.12. Application of the Diabetes Self-management program with action study strategy was successful in community setting for improving participants' subjective and objective outcomes. Action research method guides the practitioner to tailor the program to respond for the participants and field needs.

  • The purpose of this study is to classify research methods used in Korean language education studies with a focus on identifying how and what quantitative research methods are utilized in these studies. Analyzing articles published in the Journal of Korean Language Education from 2005 to 2016, we found a trend that as a replacement for secondary research, primary research played a more prominent role after 2010, as the number of quantitative studies and studies using mixed methods increased. We also found that within quantitative studies of Korean language education, research themes and statistical analyses became diversified after 2010. In order for quantitative research to contribute continuously to Korean language education, the quality of research has to improve. In particular, quantitative researchers in this area should: (a) increase their general understanding of statistical methods, (b) conduct "power analysis" to determine the appropriate sample size for hypothesis testing, and (c) be aware of measurement issues such as measurement equivalence and DIF when measuring latent psychological constructs. It is also important to notice that these points above should be considered carefully in the planning and designing stage for researchers.

  • By direct sequencing of 12 STS marker, we identified 10 polymorphic SNPs. As a result of genotype frequency analysis between 10 polymorphic SNPs and extreme population (n=20) for marbling score in Hanwoo (n=233), there was over 40 percent of frequency difference of HWSNP_1-1 and HWSNP_9-4 SNP. HWSNP_1-1 SNP was significantly associated with marbling score in large-scale population (n=233). Therefore we suggested that HWSNP_1-1 SNP can be useful as a positional candidate for beef quality for marker-assisted selection in Hanwoo.

  • 스마트폰의 확산에 따라 스마트폰의 교육적 용도에 대한 조사를 실시하였다. 본 연구에서는 스마트폰의 용도에 대한 양적인 조사를 연구 범위로 하고 조사방법론으로는 T-스토아의 분야별 어플리케이션 숫자를 파악하는 방법을 취하였다. 조사 결과는 어학/교육 어플리케이션의 숫자가 게임보다는 많았으나 FUN 어플리케이션에 비해서는 1/4도 되지 않는 실정이었다. 어학/교육 어플리케이션의 경우 유아와 초중고생을 위한 어플리케이션이 주류를 이루고 다음으로는 생활영어 어플리케이션이 뒤를 이었다. e-book의 경우에도 소설이 60%에 달하는 등 아직 교육적 용도로 개발된 어플리케이션의 비중이 미약하다는 사실이 조사되었다.

  • While the quantitative results of research on emotional labor that has been studied in Korea has never been minimal, most of the researches that have been conducted are limited to generalization by empirical analysis studies limited to single industry cases. A more integrated approach is needed in addition to quantitative research methods in order to research results that can be generalized when the importance and interest in emotional labor is increasing. Therefore, this study analyzed in-depth 112 articles published in the field of management in Korea, which were searched under the keyword emotional labor, using KCI from 2008 to 2018. To this end, the research trends of emotional labor, such as the concept, and the method of analysis, were reviewed from various aspects and presented future research directions. This research result attempted to contribute not only to academic contribution to emotional labor but also to the expansion or integration of the application area to the internal mechanisms of emotional labor.

  • The purpose of this study was to identify current trends in music therapy literature in Korea in order to provide the groundwork for future research. Therefore, 122 articles from the Korean Journal of Music Therapy (KJMT) from 1999 to 2012 and 76 articles from the Journal of Music and Human Behavior (JMHB, formerly known as Korean Journal of Music Therapy Education) from 2004 to 2012 were analyzed. Analysis was performed by identifying the frequency and percentage of the following items: type, population, topic, and methodology of published articles. In addition, the results obtained were compared and contrasted between these two publications. Overall, it was found that there was a high prevalence of descriptive studies (KJMT, 46%,; JMHB, 45%), applied research (KJMT, 51%; JMHB 66%), and quantitative studies (KJMT, 82%; JMHB 37%). In addition, ordinary people with no particular diagnosis were the most often studied population (34%). Differences were found in that a historical study was only found in KJMT whereas a philosophical study was published only in JMHB. Further analysis revealed that JMHB included a higher proportion of applied research than KJMT. In KJMT, quantitative research was appeared twice as often as qualitative and mixed-method research combined. On the other hand, a similar number of each of the three methodological types of studies appeared in JMHB. In conclusion, this study indicates that more effort should be made to increase the quantity and improve the quality of professional publications in the field of music therapy in Korea.
