이 연구는 십대출산기혼모의 부모됨 경험과 그 과정에서 나타난 다양한 지지적 관계의 역할, 십대출산기혼모의 적응과 성숙의 가능성에 대해 밝히고자 하는 목적에서 수행되었다. 온라인 커뮤니티를 통해 전국에서 십대에 임신과 출산을 경험하였으며 아이의 친부와 혼인한 여성 17명을 모집하여 일대일 면담을 통해 자료를 수집하였다. 수집된 자료는 Strauss(1987)의 `개방적 코딩`, `중추적 코딩`, `선택적 코딩` 방법을 사용하여 분석하였으며, `참여자 검토` 과정을 통해 연구결과의 신뢰도를 확보하고자 노력하였다. 이 연구에서는 십대 양육모의 적응에 영향을 미치는 사회적 지지로서 원가족과 배우자, 자조모임에 초점을 두고 자료를 분석하였다. 자료 분석 결과, 십대 청소년의 임신이 출산과 양육, 혼인으로 이어지도록 하는 데 결정적인 영향을 끼친 것은 아이의 친부의 임신에 반응과 대처였으며, 아이의 친부가 부모됨의 과정에서 가장 큰 지지원으로 나타났다. 또한 원가족이 적극적으로 지지를 제공할수록 청소년 부모의 적응과 성숙에 큰 도움이 되는 것으로 나타났다. 온라인 커뮤니티를 통한 자조모임도 십대출산기혼모의 지지원인 것으로 나타났다. 연구 참여자들은 이와 같은 지지적 관계를 통해 자신의 삶과 새로운 가족에 적응하였으며, 자신의 삶에 만족하고 미래를 낙관적으로 평가하고 있음을 것을 알 수 있었다. 이 연구는 십대 청소년의 부모됨이 원가족, 배우자와의 지지적 관계를 확립한다면 적응적 이고 성숙된 삶으로 이어질 수 있음을 발견하였다는 점에서 의의가 있다. 또한 온라인을 통한 또래 양육모 자조모임이 십대 양육모에게 중요한 지지원임을 발견한 것도 의의가 있다. 이를 통해 십대 양육모에 대한 시각을 전환할 필요성이 드러났으며, 적응을 돕기 위해서는 다양한 지지 체계를 통합적으로 포함하는 복지 프로그램이 제공되어야 함을 알 수 있었다. The purpose of this research was to discover the experiences as a teenage mother, the role of diverse support, and the possibility of adaptation and maturity. The participants were 17 married mothers who gave birth to a baby at teenage and they were recruited through online communities. One-to-one in depth interview was performed in nine cities, South Korea. We analyzed interview data by focusing on social support from which a married teenage mother could obtain; family of origin, a spouse, self-help group. Result showed that spouse`s response and reaction had a decisive effect on leading a teenage mother`s pregnancy to childbirth, parenting and marriage. The spouse`s support was the greatest source for participants in experience of being a parent. The support from family of origin was also an important factor. The more they receive support, the better participants adjust to their lives. In addition, self-help group through online communities was another important supporting factor for them. From those support, participants finally became well-adapted to their new lives and new families, and were satisfied with their lives with a positive outlook toward their future. The result revealed that being a teenage mother can lead to adaptive and mature life if they establish a healthy relationship with their family of origin and spouse. More importantly, the online self-help plays a great role in adaptation for a teenage mother. This research emphasizes the necessity of changing views toward teenage parenthood and an integrated social program in diverse support systems.

Objectives: This study was conducted to reveal the biological basis of dental plaque and preschool children’s dental health status through repetitive and continuous toothbrushing instruction to preschool children, using quantitative criteria, and to emphasize the importance of the role of an oral health manager for the prevention of dental caries. Methods: After IRB approval, toothbrushing instruction and oral microbial specimen collection were conducted with children of preschool age at the Daycare Center attached to D. University, Busan. Specimens from 27 children were characterized by analysis with real-time multi-chain enzymatic polymerization reaction technique at an agency specializing in genetic analysis. Results: In a survey of the children’s dental health behaviors, 48.1% responded that the toothbrushing time is 91 to 150 seconds; 66.7% responded that the frequency of toothbrushing is more than three times per day; 81.5% stated that they performed tongue brushing; and 81.5% brushed their teeth. Regarding levels of dental cariogenic bacteria, after children received continuous toothbrushing instruction, there were reductions in both Streptococcus mutans and Streptococcus sobrinus. Regarding toothbrushing time, the time increased in relation to the presence of instruction. Regarding Quigley Hein Index, the index decreased in the early and middle periods upon addition of instruction, then increased in the middle and later periods. Conclusions: Through persistent and repetitive toothbrushing instruction, healthy behavior can be positively established in children of preschool age; it is necessary to prepare institutional measures so opportunities for dental health education can be consistently provided and maintained. In the future, it will be necessary to conduct a follow-up study to verify the factors affecting toothbrushing time and volume of oral pathogens.

It is common to quantify the concept of interest in the social and human sciences to test a research hypothesis. In such a case, it is strongly recommended to investigate if the procedure is appropriately designed and implemented according the research purpose since the quantification procedure highly affects the result of statistical analysis. In this work, we propose a visualization tool which enables us to check the construct validity of a measurement tool (such a questionnaire) in a concise and convenient way based on a penalized factor analysis model. We illustrate our method with numerical simulation and real data analysis. 인문사회학 분야에서와 같이 개념적인 주제에 대한 연구가설을 검정하기 위해서는 연구 대상이 되는 개념을 수량화하여 통계적 분석을 실시하여야 한다. 이러한 경우 연구결과에 대한 해석이 설문조사에 의한 수량화과정에 깊이 의존하기 때문에 연구자가 측정도구인 설문지가 연구목적에 부합하게 제대로 만들어졌는지 검정하는 것은 필수적인 과정이라고 할 수 있다. 본 논문에서는 흔히 사용되는 요인분석에 의한 측정도구 타당도 평가를 개선할 수 있는 시각화 방법을 제시하고 모의실험과 실제사례분석을 통해 그 유용성을 예시하였다.

Recently, as the process of the MOS device becomes more detailed, and the degree of integration thereof increases, many problems such as leakage current due to an increase in electron tunneling due to the thickness of SiO₂ used as a gate oxide have occurred. In order to overcome the limitation of SiO₂, many studies have been conducted on HfO₂ that has a thermodynamic stability with silicon during processing, has a higher dielectric constant than SiO₂, and has an appropriate band gap. In this study, HfO₂, which is attracting attention in various fields, was doped with Al and the change in properties according to its concentration was studied. Al-doped HfO₂ thin film was deposited using Plasma Enhanced Atomic Layer Deposition (PEALD), and the structural and electrical characteristics of the fabricated MIM device were evaluated. The results of this study are expected to make an essential cornerstone in the future field of next-generation semiconductor device materials.

본 연구는 버크셔 품종에서 PRLR3와 RBP4 후보유전자의 두 개의 대립유전자가 산육형질과 번식형질에 미치는 영향을 조사하였다. 5,919두의 혈통자료, 3,480두의 산육기록과, 244두의 모돈의 775마리의 산자기록을 이용하여 유전능력 평가를 수행하였다. 유전자형 분석은 144두와 156두에서 PRLR3와 RBP4 유전자의 유전자형을 각각 분석하였다. 평가된 개체들의 육종가를 이용 두 마커의 유전자형 효과와 유의 확률을 추정한 결과 PRLR3 유전자는 번식형질의 총산자수(TBN)와 생존산자수(NBA)에서 -0.28과 -0.13두의 상가적 효과를 각각 나타내었다. RBP4 유전자는 일당증체량에서 10.58 g의 우성적 효과를 나타내었다. 그러나 RBP4 유전자의 다형성은 번식형질의 총산자수(TBN)와 생존산자수(NBA)에서 -0.34와 -0.33두의 상가적 유전적 효과를 각각 나타났다. 따라서 PRLR3와 RBP의 B 대립유전자를 선호하는 MAS (Marker Assist Selection) Scheme은 버크셔 품종의 산자수의 개량에 이용할 수 있을 것이다. Two diallelic markers at candidate gene loci, the prolactin receptor 3 (PRLR3) gene and the retinol-binding protein 4 (RBP4) gene were evaluated for their association with growth and litter size traits in Berkshire. Genetic evaluation was conducted for 5,919 pigs with pedigree information, which included 3,480 growth performance records and 775 litter size records of 224 sows. From the same herd, genotyping was carried out on 144 and 156 animals for PRLR3 and RBP4, respectively. After assigning a genotype to subjects in which both parents had a homozygous genotype, numbers of genotyped animals increased to 474 and 338, for the PRLR3 gene and RBP4 gene, respectively. The genotype effects of two markers were estimated with breeding values of the genotyped animals. The additive effects of total number of piglets born and number of piglets born alive in the PRLR3 locus were -0.28 and -0.13, respectively. The dominance effect of the RBP4 locus on average daily gain was -10.58 g. However, the polymorphism of the RBP4 locus in total number of piglets born and number of piglets born alive has shown -0.34 and -0.33 of the additive genetic effects. In view of the results, MAS (marker-assisted selection) favoring B alleles of RBP4 and PRLR3 loci could potentially accelerate the rate of the genetic improvement in the litter size traits.
