Chromosomal microarray (CMA) is primarily recommended for detecting clinically significant copy number variants (CNVs) in the genetic diagnosis of developmental delay, intellectual disability, autism, and congenital malformations. Prenatal CMA is recommended when a fetus has major congenital malformations. The main principles of CMA can be divided into array comparative genomic hybridization and single-nucleotide polymorphism arrays. In the current CMA platforms, these two principles are combined, and detection of genetic abnormalities including CNVs and absence of heterozygosity is facilitated. In this review, I described practical assessment of CMA testing regarding to laboratory management of CMA, interpretation of CNVs, and special considerations for comprehensive genetic counseling.

The weapon system applies the rule that the system engineering procedure must be applied at the acquisition stage. Naval ships, which are one of the important naval weapon systems, take a long period of time to acquire, and the leadership must be commissioned. Therefore, in order to acquire a naval ship, high risk management is necessary, and it is necessary to promote business success through effective application of system engineering which is a scientific management method. However, in the case of naval ships, there are no specific procedures and methods for applying the system engineering. Therefore, research on application method of system engineering which can be easily used by person in charge is necessary. This should have a simple approach to ensure effective business performance by systematically refining and simplifying existing works. QFD (Quality Function Deployment) is a way to improve product satisfaction, impress customers, reduce defective products, reduce design errors, and reduce costs. This systematically develops these mutual relationships by converting the needs of customers into quality characteristics of products and defining them as the design quality of products considering the functions, quality, and process elements of parts. The purpose of this research is to present concrete methodology at the practical level using QFD in a way to ensure traceability of requirements which is an important element of system engineering.

Purpose - The purpose of this study is to examine the influence of effective role-play and training on employee education satisfaction and customer orientation. Evidence of the suggested objective is obtained by monitoring the effectiveness of hotel service training. Research design, data, and methodology - Data were collected from 280 role-play sessions performed in a Korean Hotel and examined using a frequency analysis, reliability/validity assessments, correlation analysis, and regression analysis using SPSS 19.0. Results - 1) Entrepreneurs and training instructors should enthusiastically apply service education in order to enhance each employee d evaluation in terms of customer satisfaction and customer orientation. 2) The most effective factor on customer satisfaction and orientation is the instructor's qualifications. 3) Since a higher level of education-training satisfaction leads to better customer orientation, effective education-training is essential to achieve this result. Conclusions - The study was able to obtain practical evidence that can confirm that service education-training through role-play positively affects employee customer service orientation. In future advanced research on training effects on customer orientation, various internal factors of a business should also be considered.

This paper is intended as an opening of a dialog on how to apply platform thinking in the development of innovation environments. It will briefly describe a new STP (Science and Technology Park) concept called 3GSP (Third Generation Science Park), which is gaining momentum in Finland. The paper explains the fundamental changes that are currently taking place in the global innovation environment and explains why platform thinking is becoming an essential element in ecosystem development. The theoretical background and classifications of platforms are described and the benefits to be gained from STP perspective are highlighted. The paper emphasizes especially the role of so called 'competence platforms' and explains the main characteristics of a fully working competence platform. The role of competence platforms in understanding serendipity and as a fundamental factor in building the team is also highlighted. The paper analyses from STP perspective several practical examples, where platform thinking supports the emergence of new innovation environments, including Urban Mill (Finland) and Meetberlage (Netherlands). The requirements for comprehensive competence platform services are presented and their potential to support community building and therefore ecosystem development is illustrated. This analysis will provide STP practitioners with new models for applying platform thinking and will help to establish co-creation, open innovation and serendipity management practices. The case studies presented will help STP management teams to evaluate the benefits of competence platforms in different contexts.

The aim of this research is to contribute to enhancing the competitiveness of automotive parts suppliers while departing from the dependent relationship structure, by developing and interpreting factors that affect sale, which are financial achievements, in a practical way. The research data covered 200 companies from 2013-2017. The study hypothesis was verified by dividing the hypothesis into Model1 with control variables only and Model2 with control variables in independent variables. As a result of hypothesis testing, regarding sales, only capital size showed to have an effect in Model1, while in Model2, asset size, number of employees and joint ventures with foreign companies did but the other remaining factors did not. In particular, the results showed that an increase in financial performance required 'Economies of scale', and that companies that concentrated on a small number of items, diversified products into four or more items, or owned two to four suppliers, reaped positive results in financial performance. Therefore, in addition to the selection and concentration of corporate management for production items and account management, applying strategies, like the inter-company M&A, consortiums and co-branded strategies to achieve 'Economy of scale', would highly enhance the financial performance of automotive parts suppliers.

The purpose of this study was to compare the curricula majored in fashion retail related area at 4-year colleges in Korea and the USA. Courses were divided into 15 elements including basics, design, production, textile, marketing, industry, merchandise planning, promotion, consumer behaviour, management, business, organization, internship and etc.. The research findings were as follows: 1. Most of 'industry' related majors in Korea consisted of fashion manufacture-oriented curricula elements including design, pattern making, tailoring, draping and textile sciences. 2. Fashion Marketing major stressed on a merchandising element and a marketing one, and the Fashion major focused on the promotion element and the merchandising element as well. However, the retail element was less focused than other elements in the Korean colleges. 3. Fashion Retail related majors in the USA College were likely to focus on the practical fashion retail management elements including retail, marketing, management, business, organization behavior and internship specialized by the major. The different curricula between two countries were clearly existed in terms of the major name and the construction of the course element. The results made in the research would be applied with some modification or adjustments in the fashion retail oriented curricula in order to produce the competitive retail human resource in Korea.

The majority of research on institutional theory suggests that the new institutional practices presented by national governments and expert groups is a legitimate demand by society, and that the organization is a passive actor that accepts it. However, individual organizations often perform so-called decoupling acts that run their organizations in their own way instead of following the way the system requires, despite the pressures of a strong institutional environment. In this study, the decoupling behavior of these organizations can be varied by the characteristics of the highest decision maker in the organization based on the upper-echelon theory(UET) even if there is no difference in pressure experienced by individual organizations, and their relationship is empirically analyzed among secondary educational institutions that are relatively strongly regulated by the government. According to the analysis of 192 high schools in Korea, the female principal, the younger the principal, and the higher the educational background, the more likely they are to engage in decoupling behavior that are different from the intent and content of government policies. Therefore, from the results of this study, meaningful theoretical and practical implications can be provided for researchers and managers in the field of knowledge management research.

Cost and schedule are the major concerns for the successful construction project management. The four dimensional CAD (4D CAD) integrating graphical data and scheduling data has also been an area of research interests for improving construction controls. In order to achieve the benefits from these areas in an integrated way, this study proposes a 4D-EVMS system for the owners. Managerial requirements for cost and schedule control for the owners are identified first. A 4D-EVMS model is then proposed which provides functional flexibility in order to enhance the efficiency of the system. Lessons learned and practical implications are briefly summarize.
