목 적: H. pylori 감염률은 생활수준과 밀접한 관계가 있어 경제적으로 어려울수록 감염률이 높아지며 사회생활을 하면서 나이가 증가함에 따라 같이 올라간다. 소아에 있어서 선진국에서는 5% 미만의 감염률을 보이고 있고 우리나라에서는 6세에서 15세까지의 정상아동에 16.5%의 감염률이 보고된 바 있다. 부모연령의 감염률이 높은 우리나라에서 5세 이하 정상아동에서의 H. pylori 감염률은 혈액채취 등의 어려움으로 현재까지 거의 조사되어 있지 않아 H. pylori 특이 IgG 항체검사를 이용, H. pylori의 감염률을 알아보고자 하였다. 방 법: 1995년 서울시내 3곳의 어린이집을 방문하여 2세에서 5세까지의 220명(2세 24명, 3세 54명, 4세 95명, 5세 47명)에 대하여 혈액을 채취하고 ELISA를 이용한 IgG GAP test로 H. pylori의 감염률을 조사하였다. 결 과: 1) 총 220명중 양성은 2세 1명, 3세 2명, 4세 1명, 5세 1명의 총 5명으로 양성률은 2.3%였다. 2) 약양성(equivocally probable positive)은 2세 3명, 3세 3명, 4세 4명, 5세 3명의 총 13명으로 220명중 5.9%였다. 결 론: 우리나라 2세에서 5세까지의 정상아동에 있어서 H. pylori의 감염률은 2.3~8.2%로 생각되어지며 선진국에 비교하면 아직도 높은 수치로 향후 가족내 감염 등 집단감염과 사회경제적 환경의 변화에 따른 감염률의 추이에 대해 지속적인 연구가 필요할 것으로 본다.

Fumonisins are a group of mycotoxins produced by a pathogen Fusarium verticillioides in infected maize kernels. Consumption of fumonisin-contaminated maize has been implicated in a number of animal and human illnesses, including esophageal cancer and neural tube defects. Since the initial discovery, chemistry, toxicology, and biology of fumonisins as well as the maize-Fusarium pathosystem have been extensively studied. Furthermore, in the past decade, significant progress has been made in terms of understanding the molecular biology of toxin biosynthetic genes. However, there is a critical gap in our understanding of the regulatory mechanisms involved in fumonisin biosynthesis. Here, we review and discuss our current knowledge about the molecular mechanisms by which fumonisin biosynthesis is regulated in F. verticillioides. In addition, we discuss the impact of maize kernel environment, particularly sugar and lipid molecules, on fumonisin biosynthesis.

The study was performed to develop standards for nursing practice. The quality and quantity of medical services, including nursing services, has been determined to date by the availability of providers rather than by the actual needs of the patients. In fact, there has been a serious gap between expected and actual servces. In order to provide high quality nursing services and to enhance professional status, the nursing profession should define their practice in a measurable way and identify the client outcomes to which they contribute. Therefore, this research was conducted through the three phases as follows : (1) Evaluation of current nursing practices and environment, and analysis of actual patient needs, by means of questionnaires. (2) Literature review to define the nature, purpose, and standards of professional nursing practice. (3) Expert group's modification of existing standards by integrating the results of first two phases. As a result, standards for each area of nursing practice were developed, such as shown in Table 3 and Table 4. However, these standards must receive ongoing attention by the profession to assure that they remain current and reflect advances in nursing knowledge and clinical technology.

Project cost is an important concern in any construction project. Although there has been a lot of studies on factors affecting the cost of construction projects, there seems no consensus as what cost factors have direct influence on the cost of civil engineering projects. This study therefore aims to bridge the current knowledge gap by examining quantity surveyors' perception of the factor structure among nineteen costing attributes identified based on literature review. Questionnaire was used to elicit responses from quantity surveyors working in the Hong Kong construction industry. Principal component analysis is conducted to extract the factor structure of the cost attributes and the attributes are grouped into three factor components, namely the contract management factor, the project management factor and the monetary value factor. Understanding these cost impact factors could be crucial in managing civil engineering projects, since it allows the project stakeholders and quantity surveyors to take precautionary steps to identify the cost management problems and areas for improvement and could even help to avoid cost deviations in engineering projects.

Two-dimensional van der Waals (2D vdWs) materials have been extensively studied for future electronics and materials sciences due to their unique properties. Among them, black phosphorous (BP) has shown infinite potential for various device applications because of its high mobility and direct narrow band gap (~0.3 eV). In this work, we demonstrate a few-nm thick BP-based nonvolatile memory devices with an well-known poly(vinylidenefluoride-trifluoroethylene) [P(VDF-TrFE)] ferroelectric polymer gate insulator. Our BP ferroelectric memory devices show the highest linear mobility value of $1159cm^2/Vs$ with a $10^3$ on/off current ratio in our knowledge. Moreover, we successfully fabricate the ferroelectric complementary metal-oxide-semiconductor (CMOS) memory inverter circuits, combined with an n-type $MoS_2$ nanosheet transistor. Our memory CMOS inverter circuits show clear memory properties with a high output voltage memory efficiency of 95%. We thus conclude that the results of our ferroelectric memory devices exhibit promising perspectives for the future of 2D nanoelectronics and material science. More and advanced details will be discussed in the meeting.

In order to understand information system post-adoption phenomena, the expectation-confirmation model (ECM) was proposed. Past studies based on the ECM focus on a referent centered on the target IS being studied. The effect of this reference, captured through confirmation, has been strongly shown. However, the saliency of two additional reference effects, captured through self-image congruity and regret, has not been explored. In order to fill this knowledge gap, this paper attempts to develop a research model that extends the ECM by incorporating self-image congruity and regret as well as perceived enjoyment. For this extension, we synthesize the extant literature on continued IS use, self-image congruity, and regret. The analysis results tell us that self-image congruity plays a key role in forming two post-adoption beliefs, perceived usefulness and perceived enjoyment. It is also found that the absolute effect of regret on continuance intention is larger than those of other antecedents identified in IS. Overall, this study preliminarily confirms the saliency of self-image congruity and regret in post-adoption phenomena. Our study results is likely to help the IS community systematically address unexplored effects of self-image congruity and regret.

Service importance has been growing increasingly as competition element of enterprises according to going on rapid softness, information and knowledge of industrial infrastructure recently. Quality management system that implemented in manufacturing sector have been spreading rapidly to service company, but the company performing pure engineering service only in construction fields performed mainly the evaluation on the operational aspect such as degree of implementation of the established system because it is difficult to objective evaluation on the activity of the established quality management system or quality assurance system. This study would like to make on offer the improvement points based on the evaluation of service quality and the itself evaluation result through the questionnaire on the service offerers and customers using the pre-qualified SERVQUAL model in establishment of the improvement goal of the company. According to the result of this study, it is analyzed a gap and required to establish a counter-plan to correct many gaps discovered between the real offered level and the expect level of custom.

In this paper, we surveyed state-of-the-art health and wellness platforms. The motivation of this paper is to review the state-of-the-art health and wellness platforms and their maturity with respect to adoption of latest enabling technologies. The is review is classified into four categories: healthcare systems, AI-assisted healthcare, wellness platforms, and open source health and wellness initiatives. From this comprehensive review, it can be stated that the contemporary healthcare systems are well-adopting wellness due to the concentration shift towards prevention. Thus, the gap between health and wellness is slowly yet carefully entering gray area. Where both the domains can freely invoke each other's services, and supporting enabling technologies. Furthermore, the biomedical researchers and physicians are no longer carrying the myopic views of trusting their knowledge for diagnosis. AI-assisted technologies based on machine learning and big data are influencing today's prognosis with trust and confidence.
