In this study, the predictive power of family support on the level of professional maturity of students studying at Kars Fine Arts High School in the choice of profession was examined. The research was determined as a relational survey model, one of the survey models. The study group consisted of students studying at Kars Fine Arts High School in the 2019-2020 academic year. Data, the personal information form containing the demographic characteristics of the participants and the Professional Maturity Scale (PMS) and Family Support in Choosing a Profession scales were used to determine the level of professional maturity of family support in choosing a profession. In the analysis of the data, t-test, one-way ANOVA test, and regression analysis were performed for independent samples. It has been determined that the level of professional maturity of family support in choosing a profession differs according to the income level of the family. There is no significant difference in the department variable in the choice of profession. It has been seen that the power of family support to predict the level of professional maturity in the choice of profession of the students is the predictor of family support in the choice of profession.

Purpose: The innovation of using BIM systems for construction projects can be a factor stimulating the development of the construction industry. Although BIM systems have been known for several decades, their implementation rate is considered low. The aim of the research was to identify issues that may influence the effectiveness of BIM implementation and to propose concepts for certain solutions to improve it. Methodology: The literature review included an analysis of books, professional journals, and information published on the Internet. The economic practice research included: participant observation combined with document review in four companies using BIM at various levels of maturity; expert interviews with managers from four other companies using BIM. Findings: Specific features of construction projects that influence the use of BIM were identified, BIM concepts were summarised in context, the links between the life cycle of a building and a construction project in relation to BIM were defined, an attempt was made to determine the full maturity of BIM implementation, and factors hindering the implementation of BIM in companies were summarised. The market offer was analysed and a model for selecting BIM software was proposed. The advantage of the research methods used, in the authors’ opinion, is their diversity, which allows for mutual verification of the obtained results, even despite the relatively small number of observations and interviews conducted. Research limitations: The limitation of the conducted research was its narrow focus on a relatively small group of companies, lacking companies with a high level of BIM maturity and those using BIM for facility management. Practical implications: The identified conditions resulting from the nature of the investment process and the construction project may influence the practical approach to BIM implementation. Maturity assessment criteria can be used as a tool to identify the stage of BIM implementation in a company. The identified factors hindering BIM implementation can be the basis for identifying and removing barriers in the company. The proposed software selection model can serve as a suggestion for developing your own rules of conduct. Originality: The relationships between the investment process and the construction project were identified, while defining the specifics of the construction project in the context of BIM implementation. Relationships between the construction project cycle and the life cycle of a facility in BIM. Criteria for assessing a company's readiness to use BIM at the highest level of maturity. Factors inhibiting the implementation of BIM. A model for selecting BIM software. The results may be useful for managers of companies implementing construction projects. Keywords: BIM, Building Information Modeling, Construction projects, Computer-aided projects, BIM implementation. Category of the paper: Research paper.

Size, complexity, and human dependency on software--based products have grown dramatically during past decades. Software developers are struggling to deliver reliable software with acceptable level of quality, within given budget and schedule. One measure of software quality and reliability is the number of residual faults. Therefore, researchers are focusing on the identification of the number of fault presents in the software or identification of program modules that are most likely to contain faults. A lot of models have been developed using various techniques. A common approach is followed for software reliability prediction utilizing failure data. Software reliability and quality prediction is highly desired by the stakeholders, developers, managers, and end users. Detecting software faults early during development will definitely improve the reliability and quality in cost-effective way.KeywordsSoftware ReliabilityFault PredictionSoftware MetricsCapability Maturity ModelTest Case PrioritizationThese keywords were added by machine and not by the authors.

We empirically examine the relationship between software design modularity and software quality in open source software (OSS) development projects. Conventional wisdom suggests that degree of software modularity affects software quality. An analysis of 203 software releases in 46 OSS projects hosted on SourceForge.net lends support for a more complex relationship between software modularity and software quality than conventional wisdom suggests. We find that software modularity is associated with reduced software complexity, an increased number of static software bugs, and a mixed relationship with the percentage of bugs closed. We do not find empirical evidence supporting any relationship between modularity and other measures of customer satisfaction. In addition to empirically testing the relationship between modularity and quality, we introduce new measures of software modularity and software quality. Implications are developed for the theory of modularity and the practice of software development.

이 연구는 2005년부터 조사된 교육종단연구(KELS) 5차(2009), 7차(2011), 9차(2014) 자료를 활용하여 진로성숙도에 따른 특성화고 졸업생들의 잠재집단을 유형화하고, 잠재집단 간 전이 양상을 확인하여 그 영향 요인을 알아보고자 하였다. 이를 위해 잠재전이분석(latent transition analysis: LTA) 방법을 사용하여 전이패턴을 확인하고 로지스틱 회귀분석을 통해 이에 영향을 미치는 변인들을 탐색하였다. 분석 결과 특성화고등학교 졸업생들은 고등학교에 재학 중인 18세 시점(5차)에서 3개의 잠재집단(높은 성숙수준, 중간 성숙수준, 낮은 성숙수준), 23세 시점(9차)에서 3개의 잠재집단(높은 성숙수준, 중간 성숙수준, 낮은 성숙수준)으로 분류되었다. 두 시점의 잠재집단 간 전이확률을 확인한 결과, 모든 잠재집단에서 절반 이상이 다른 잠재집단으로 전이되어 다양한 요인에 의해 진로성숙이 변화될 수 있다는 것을 확인하였으며 ‘중간 성숙수준’ 집단에서 ‘중간 성숙수준’을 유지하는 경우가 40.7%로 확률이 가장 높았고, 다음으로 ‘중간 성숙수준’집단에서 ’높은 성숙수준’으로 전이되는 경우가 16.9%로 나타났다. 전이 패턴을 ‘상향’, ‘유지’, ‘하향’으로 재구성했을 때 이에 영향을 미치는 요인은 전체 표본에서는 성별, 목표 대학 및 학과 여부, 부모의 감성적지지(9차)인 것으로 나타났다. 취업자 유형과 진학을 한 번이라도 경험한 유형으로 나누어 분석한 결과에서는 상향 패턴 대비 하향 및 유지 패턴에서 각각 대학만족도(9차), 목표 일자리 일치도(9차) 변인이 유의하였고, 성별은 진학을 경험한 유형에서만 유의하였다. 이상의 연구 결과를 토대로 결론에서는 특성화고 재학생의 진로성숙 수준에 따른 진로교육의 접근 방안과 진로설계를 위한 시사점을 제시하였다.The purpose of this study is to identify how career maturity of vocational high school graduates is changing across two different time points. Using the KELS(2005) 5th(2009), 7th(2011), and 9th(2014) wave dataset, Latent profile analysis and latent transition analysis (LTA) was conducted to evaluate the clustering of career maturity and transition probability. Logistic regression analysis was used to investigate influential variables. Among 579 graduates surveyed across the years, Vocational High school graduates were divided into three maturity class(high maturity level, middle maturity level, low maturity level) at both 5th and 9th wave. Result of the transition probability between classes of each time points, more than half of all respondents were transferred to other class. To analyze the factors affecting the transition, transition pattern was reclassified as upward , maintained and downward by direction of change. Gender and willing to go university has important roles on the downward changing and ideal job consistency is key factor to ‘downward’ pattern but only for employed case. However, parents emotional support has positive effect on maturity changing. The study inform basic characteristics of student in vocational education area, and also career design and career guidance targeted at vocational high school students. Based on the results, practical and theoretical implications for career education and career guidance in vocational high school were suggested.

Este artigo aplica a técnica de convergência proposta por Phillips e Sul (2007) para um painel de índices transacionados nas principais bolsas de valores no mundo. Corroborando Antzolautos et al. (2009), não se evidencia uma tendência de convergência comum. O Índice da Bolsa de Valores de São Paulo (Ibovespa) consiste no mais antigo dos que compõem o grupo com maior nível na tendência observada nas dinâmicas de transição, o qual é composto por índices voláteis de bolsas com razoável nível de maturidade, situadas principalmente em países da América Latina e Central, com elevada inflação. O segundo clube compreende a maioria das bolsas analisadas, caracterizadas por um maior nível de maturidade e tradição dos mercados financeiros e de desenvolvimento das economias, situadas na Europa, América do Norte e Ásia. O terceiro clube compreende poucas bolsas, sem padrão aparente. Os padrões macroeconômicos, geográficos e financeiros evidenciados podem ser úteis na inferência sobre a recuperação do mercado financeiro após a crise financeira.

In this context, computer models can help us predict outcomes and anticipate with confidence. We can now use cause-effect modeling to drive software quality, moving our organization toward higher maturity levels. Despite missing good software quality models, many software projects successfully deliver software on time and with acceptable quality. Although researchers have devoted much attention to analyzing software projects' failures, we also need to understand why some are successful - within budget, of high quality, and on time-despite numerous challenges. Restricting software quality to defects, decisions made in successful projects must be based on some understanding of cause-effect relationships that drive defects at each stage of the process. To manage software quality by data, we need a model describing which factors drive defect introduction and removal in the life cycle, and how they do it. Once properly built and validated, a defect model enables successful anticipation. This is why it's important that the model include all variables influencing the process response to some degree.

Purpose: The overriding objective of this investigation is creating and deploying a new Lean longevity matrix, to enable organisations to reliably gauge the juncture of leanness achieved, steps necessary to move towards the next level and where dedicated resources are necessary. This was achieved by presenting and piloting a new maturity matrix addressing limitations of the existing ones. Methodology: The methodology consisted of a literature review coupled with 15 Case Studies representing 15 disparate UK manufacturing organizations. This incorporated integrating primary data capture through structured interviews from a statistically representative sample. Findings An all-embracing matrix was developed facilitating improved Lean implementation records whilst steering organizations towards higher Lean maturity levels. These aims are attained by incorporating the necessary assurance and appropriate prioritization by distinguishing areas necessitating dedicated resources safeguarding sustainability of the initiative preventing backsliding. Practical implications Extensive metrics were incorporated scrutinising the prevailing culture and change management systems. By permitting a self-assessment eradicating the bureaucracy accompanying matrixes it permits a reliable determination of juncture an organization has attained. Feedback steers a possible course of action navigating the organization towards the next phase. Originality: The matrix tackles an existing void found in most Lean maturity matrices, specifically addressing two aspects: firstly, establishing whether an organization has adopted Lean as a philosophy and, secondly, distinctively deducing the Lean phase attained. Subsequently, informing an organisation regards steps facilitating it to move to a higher maturity level preventing regression.

Introduction. In recent decades the upsurge in research on human spirituality and health has been observed. The study of spirituality and its relationship to health is possible by assessing the level of internal development (maturity) of man as a person. The aim of the study is to determine the level of personal maturity of sick and healthy people and to establish its relationship to the integral conclusions about the functional state of the cardio-respiratory system. Material and methods. 560 people, men ⸻ 301 (53.75%), women ⸻ 269 (46.25%). Average age of the subjects ⸻ 35.00±17.75 (95% confidence interval: 33.52–36.47) years. There were 337 patients (60.18%) suffering from chronic diseases, and 223 ( healthy patients (university students) (39.82%). Height, body mass, heartbeat rate, respiratory rate, blood pressure, vital capacity, muscle strength of the hand were measured. The functional state of the cardio-respiratory system was assessed by integral indicators: adaptive potential of circulatory system according to A. P. Berseneva, level of physical state according to O. A. Pirogova, life index, Skibinski’s index, Kerdo index, hand strength index. To determine the levels of personal maturity, a survey was conducted by Jose Stevens. Applying the levels of maturity proposed by the author ("baby", "kid", "teenager", "young man" and "adult"), low, medium-low, medium- high, undifferentiated and combined levels of personal maturity were formed, which were considered degrees of human spiritual development. Results. 53.39% (299/560) of subjects had high levels, and 35.54% (199/560) - ⸻ low levels, including undifferentiated ones, of personal maturity. It was established that a predominance of high level of personal maturity took the place in the event of satisfactory adaptive potential of the circulatory system according to A. P. Berseneva, high level of physical state according to О. А. Pirogova, full compliance of respiratory function in relation to body mass according to life index, a higher level of interaction of respiratory and circulatory organs according to the Skibinski’s index, high relative strength of the hand and the normal state of vegetative tonus according to the Kerdo index. Conclusions. There is a significant relationship between the personal / spiritual maturity of man and the functional state of the cardio-respiratory system. People with high levels of personal / spiritual maturity have a better functional state of the cardio-respiratory system than people with low and undifferentiated levels.

: The Rome Air Development Center has developed the Software Quality Framework as a means to specify software quality goals and measure software quality. Much of the work to date has focused on metrics applicable to software code. This report describes an effort undertaken to measure the quality of software products earlier in the software development life cycle, during the design phase, and to automate the capture of metric data from design media. Metrics of software quality, primarily those related to the criterion simplicity (or conversely, complexity), were reviewed. This review includes those metrics previously developed in the Software Quality Framework. Two metrics, Halstead's Software Science and McCabe's Cyclomatic Complexity were chosen for their amenability to measurement during design and their potential for automation. Two design media were used: Design Aids for Real-Time Systems, an experimental automated design tool developed at the Charles Stark Draper Laboratory; and Ada as a program design language.

The main purpose of this study was to determine the level of career maturity in a sample of university students in one public university in Jordan. The study also sought to determine differences in career maturity based on gender and educational level. The sample of the study consisted of 284 students enrolled in social studies classes. Results of the study indicated that participants had high levels of career maturity on self-knowledge, career decision-making, and career implementation. However, participants exhibited moderate levels of career maturity on knowledge of occupations, knowledge of the world of work, and career planning. The results also showed no differences in levels of career maturity based on gender and educational level except for the career planning dimension where juniors and seniors were more mature than sophomores. Finally, this study provided several recommendations with regard to preparing university students for the work environment.
