Although viruses are the most common cause of acute gastroenteritis (AGE) in humans, details about the causative viruses in AGE are largely unknown because many causative viruses are unable to be cultured by current culture techniques. In our study, fecal samples from 10 children under five years of age with unexplained AGE and 10 healthy children were investigated for RNA viruses using random priming (RP)-mediated sequence-independent single primer amplification (SISPA). The causative viruses in cases of cryptogenic diarrhea were then assessed for their potential diagnostic value. Of the 1,129 viral clones identified, rotavirus was most commonly associated with AGE (125 sequences, 22.4%). In contrast, bacteriophage was most common (43 sequences, 13.6%) in healthy children. The remaining 515 viral clones were unidentifiable. These findings suggest that investigation of cases or outbreaks of unexplained diarrhea using a metaviromic strategy is a new avenue for diagnosis.

Hepatitis A virus (HAV) positive stool samples were collected from acute hepatitis A patients during the two studyperiods of 2002 and 2011 in Seoul, South Korea, and their genetic variability was determined. From a total of 79specimens, the nucleotide sequences of the VP1 and 2A junction were successfully amplified in 27 (34.2%) samplesand subjected to sequence analysis. Genetically, there was a dramatic change in HAV subgenotypes from IA to IIIA duringthe past ten years. Sequence analysis identified that most strains belonged to genotype I, which is the main genotypeglobally. The subgenotype IA (93.3%, n=13/14) was the major subgenotype in 2002, whereas the subgenotype IIIA(69.2%, n=9/13) was predominant in 2011. Interestingly, a IIIA strain was identified from a patient who had a history oftravel to India in 2002. The finding presented provides new insight into the genetic shift of circulating HAVs in SouthKorea.

Slab panels are very important to develop asphalt concrete (AC) track for minimizing the roadbed stress due to the train load and reducing the plastic deformation of infrared-sensitive AC. In this study, the slab panel for AC track was developed through the shape design and the indoor performance test and its structural integrity has been investigated through the finite element analysis under the flexural tensile stress and the design moment according to various static load combination by KRL-2012 standard train load model and KR-C code. In order to verify the suitability of the slab panel for AC track, static bending strength test and dynamic bending strength test were performed according to EN 13230-2. Results show that the slab panel for AC track satisfies all the performance standards required by European standards such as crack loads and crack extension. 아스팔트 콘크리트(AC) 궤도는 열차 하중에 의한 궤도 하부노반의 발생응력을 최소화하고, 적외선에 민감한 AC의 노출면적을 감소시켜 온도 영향에 따른 AC 도상의 소성변형을 줄일 수 있는 슬래브 패널 개발이 매우 중요하다. 본 연구에서는 형상 설계 및 실내성능시험을 통해 AC 궤도용 슬래브 패널을 개발하였으며, KRL-2012 표준열차하중 모델 및 KR-C코드에 의한 다양한 정적 하중조합에 따른 슬래브 패널에 작용하는 휨 인장응력 및 설계모멘트를 유한요소해석을 통해 구조 안전성을 검토하였다. 또한 AC 궤도용 슬래브 패널의 설계 적합성을 검증하기 위하여, EN 13230-2에 의거 슬래브 패널 주요 위치별로 정적 휨 강도 시험, 동적 휨 강도 시험을 수행하였다. 성능 시험 결과, AC 궤도용 슬래브 패널은 균열 하중 및 균열 확대 여부 등 유럽 표준에서 요구되는 성능 기준을 모두 만족하였다.

본 연구에서는 성인의 불안정 부모애착 유형에 따라 자기정서인식과 정서조절의 매개를 통하여 대인관계문제에 미치는 영향을 살펴보고자 하였다. 이를 위해 성인 265명을 대상으로, 초기부모애착척도, 정서지능척도, 한국판 대인관계문제검사 원형척도 단축형 검사를 통해 자료를 수집하였다. 본 연구의 결과는 다음과 같다. 첫째, 불안-양가 애착은 자기정서인식과 정서조절을 순차적으로 매개하여 독립적 대인관계문제에 완전매개효과를 보이고, 의존적 대인관계문제에는 부분매개효과를 보였다. 둘째, 회피 애착은 자기정서인식과 정서조절을 순차적으로 매개하여 의존적 대인관계문제에 대해서는 완전매개효과를 보이고, 독립적 대인관계문제에서 부분매개효과를 보였다. 이러한 연구결과는 불안정 부모애착 유형에 따라 성인기의 대인관계문제에 다른 영향을 미치는 것을 의미하며, 특히 자기정서인식의 개입이 불안정 애착을 경험한 사람의 대인관계문제에 주요한 접근 방법이 될 것임을 시사한다. 이와 같은 결과를 바탕으로 논의 및 시사점, 연구의 제한점과 후속연구를 위한 제언을 하였다. This study investigated the effect of early parental attachment on interpersonal problems through the mediation of self-emotional recognition and emotional regulation in adulthood. Data were collected from 265 adults using questionnaires. We used bootstrapping techniques from Hayes' PROCESS macro program to estimate the hypothesized serial mediation. Insecure parental attachment was significantly associated with emotion recognition, both of which were in turn related to emotion regulation, and subsequently to interpersonal problems. Specifically, emotion recognition and regulation fully mediate the relationship between anxiety-ambivalent attachment and independent interpersonal problems. Otherwise, emotion recognition and regulation fully mediate the relationship between avoidant attachment and dependent interpersonal problems. These results suggest that different types of insecure parental attachment have different effects on interpersonal problems in adulthood.

The optimum track stiffness required to maintain track performance is known as the most important parameterthat determines properties of roadbed, such as the stiffness of the track substructure. Considering that no criteria exist fortrack stiffness for each type of track, it is very important to study the proper track stiffness of each track structure. In thisstudy, full-scale static and dynamic load tests were carried out to investigate the effect of track substructure characteristicson track stiffness and track modulus in slab track systems under the same upper roadbed condition. The test results indicatethat the track modulus is smaller than the proposed value when the reinforced roadbed thickness is below the designstandard. Therefore, it is necessary to reestablish design standards of track stiffness in terms of track maintenance.
