Structural Relationship of Dynamic Capabilities and Operational Capabilities: The Role of Technical Fitness

본 연구는 새로운 시장 및 기술 출현에 따라 기존의 소프트웨어 개발자들이 새로운 기술시장 생태계로 진입 및 전환을 하는데 있어서 동적 역량과 운영 역량의 구조적 관계를 조사하고 이들 사이의 관계에서 기술적합도의 매개 역할이 IT 기업의 성과에 미치는 효과를 파악하고자 하였다. 이를 위해 IT 신제품 및 신서비스개발에 참여한 경험이 있는 227명의 소프트웨어 개발자로부터 수집된 데이터를 사용하여 PLS구조방정식 모델을 적용하여 분석하였다. 실증분석 결과, 운영역량은 동적 역량과 기업성과 간의 관계를 부분 매개하고, 기술적합도 또한 본 구조모형에서 기업성과간의 관계를 부분 매개하는 것으로 나타났다. 특히, 동적 역량 그 자체로는 기업의 성과에 영향을 미치지 못하는 것으로 나타났으며 운영역량의 매개역할을 통해서 동적 역량이 기업의 성과에 영향이 미치는 것으로 나타났다. 본 연구는 기술적합도의 매개효과를 검증함으로써, 기존 및 신생 기업들이 새로운 기술 및 시장의 출현 상황에서, 새로운 분야의 진입과 전환의 단계에서 동적 역량과 운영역량이 어떻게 작동하는가를 제시하였다는 점에서 이론적 및 실무적 의미를 지니고 있다. 연구결과는 IT 기업들이 새로운 기술 및 시장 환경 변화의 맞게 변모하기 위해서는 고객의 기대를 능가하고 니즈를 선도할 수 있는 제품 및 서비스 품질 그리고 기능을 향상시키는 활동업무에 주력해야 하는 선제적인 방안을 수립할 필요성을 제시하고 있다. 연구결과를 토대로 연구의 한계 및 향후 연구방향을 제시하였다.This study investigates the relationship of dynamic capabilities, operational capabilities, and their influence on performance and introduces technical fitness as a mediating driver, which has not yet been considered in the literature. Applying partial least square-structural equation modeling to the data collected from a sample of 227 software developers experienced in a new product and service development in IT fields, the study finds that operational capabilities play a partial mediator on the relationship between dynamic capabilities and performance, and technical fitness has a partial mediating effect on the relationship between operational capabilities and performance. In particular, it shows that dynamic capabilities per se have an insignificant influence on performance but have a significant influence on performance through the mediating role of operational capabilities. It has both theoretical and practical implications in that proposing how existing and emerging firms can work in the stage of transformation or start-up under the advent of the new technologies and markets. Furthermore, it suggests that IT firms need to focus on establishing preemptive measures that enhance product and service quality and functionality that can surpass customer expectations and lead needs in order to transform new technologies and marketplace changes. Based on the results of the study, the limitations of the study and the direction of future research were suggested.

Work Safety and the Duration of Munition Testing

This paper presents the aspects of work safety and the standardization of time (duration) that relate to the diagnostic testing of munitions. This paper identifies the sources of hazards during munition disassembly, caused by the physical and chemical processes occurring during the years of service, and the hazards of non-conformities with the standard processing procedures used during the manufacture of the munitions. Munitions, given their intended use, are not usually designed for disassembly. With the manufacturing processes of munitions being monitored at every stage, and the application of proper grades or quality of the materials and components, munitions may retain their combat performance for a very long time following the expiry of their original warranty period. The extended shelf life of munitions (past the original warranty period/shelf life) can be determined with certain tests. The tests, however, require tampering with the internal structure of a munition by disassembling the munition into its component parts in order to allow assessment of the current technical condition and to project the technical fitness for extended service. Disassembly activities are hazardous and require the prior preparation of safe processes, workstations, procedures, and a comprehensive health and safety assurance system. Health and safety assurance in munition testing requires high capital expenditure to acquire sufficient engineering facilities and proper monitoring of all the disassembly activities attempted on munitions. Operator safety has the highest priority in munition disassembly; it is then pointless to regulate the time required for completing the individual disassembly operations.

Therefore, a preliminary reconnaissance survey was accomplished in the study area and then a semi-structured questionnaire was designed. By adopting simple random sampling method, the study area was surveyed covering 50 respondents in different wards to collect primary data. Results revealed that poor drainage system (PDS) is one of the most liable factors for environmental deterioration. The maximum urban drainage system was found unclosed with number of 49 (i.e., 98%). It was 34 drains were made of brick, while 17 were worst type, 32 had odor problem, 20 were not well designed, 29 had inadequacy of drains,18 with poor technical fitness, 22 wastes disposal in gutters,18 had clogging of ditches & drains, and 15 with broken road surface respectively. The consequent major environmental and health problems were flash-flooding (42%), and skin disease (38%) respectively. In case of public opinion, the highest percentage (i.e., 30%) suggested to stoutly prohibit dumping of garbage into gutters. PDS was found strongly positive correlated with its effects on environment (r=0.98) and on public health (r=0.91). Thereby, present PDS affects the environment as-well-as public health by enhancing frequent flash-floods and spreading diseases within the study area.Journal of Institute of Science and TechnologyVolume 22, Issue 1, July 2017, Page: 165-178

Influence of Different Physical Training Capacity on Young Basketball Players Preparedness

An initial training period remains relevant in managing sports preparedness, identifying the most important factors which determine the best young basketball players’ sports fitness and changes in the sports results. Constantly there is a scientific problem: what physical loads have to be chosen in order to achieve not only high results in sport, but also strengthen a child’s body. What is the scope and intensity of physical workload for different age groups and which of them are the most effective ones? The number of basketball practice training at different schools or even groups often vary depending on the fitness of players and their physical development. Reasons of increasing or decreasing the number of exercises in children sport are usually subjective and completely scientifically unfounded. For this reason, it was intended to find out what amount of exercise per week affects best children’s physical and technical fitness. Hypothesis: It is probable that one additional basketball workout per week will affect 11-14 year-olds physical and technical readiness, but will not influence their somatic physical development indicators. The aim of research: to determine how different physical loads for young players affect their somatic indicators, physical and technical fitness. The following research methods were used: physical fitness testing, technical fitness testing, mathematical statistical analysis. The study showed that in the majority of players, who were in an experimental group, height, weight and arm length indicators varied similarly, as in the control group. Therefore, the theoretical assumption that an extra amount of exercise does not make a significant impact on children’s anthropometric indicators of their physical development is confirmed. One academic year experiment showed that one extra week of basketball training had positive impact on 11, 13, 14 years old players physical performance – most of the indicators significantly improved or had tendencies for improvement. 12-year-olds basketball preparedness indicators of additional training did not change. This could lead to the fact that some of the educational methods were not properly chosen and or certain genetic characteristics of children development had influence as well.

The Influence of Anaerobic and Aerobic Fitness on the Technical Skill Ability of National Elite Male Under-18 African Soccer Players

Aim. Elite level soccer players cover about 10 km during a 90-minute game. Although running is the predominant activity in soccer, explosive movements such as sprinting, jumping and kicking are important for successful performance. The aims of this study were to determine the technical skill ability, aerobic- and anaerobic fitness of elite male under-18 African soccer players; and to determine whether a relationship exists between the technical skill ability and aerobic and anaerobic fitness. Methods. One-hundred-and-sixty-nine (n=169) elite male under-18 soccer players from eleven African countries participated in the study. Technical skill ability (dribbling, crossing, shooting, passing) was assessed using four soccer-specific tests. Aerobic and anaerobic fitness was measured through a 20-metre multi-stage shuttle run test and a repeated sprint ability test respectively. Results. The results showed that VO2max level (47.71 ml·kg-1·min-1) was much lower than indicated in literature (60 ml·kg- 1·min-1). An average total distance of 704.36 m was recorded for the repeated sprint ability test. A positive correlation was found between dribbling and both aerobic and anaerobic fitness. Results indicated differences among various playing positions with forwards producing best performance in the passing and shooting skills test, forwards and defenders possessing the highest level of aerobic fitness and goalkeepers displaying the lowest level of aerobic and anaerobic fitness. Conclusion. Aerobic and anaerobic fitness influenced the players’ ability to dribble. The African soccer players generally have a lower level of both aerobic and anaerobic fitness.

An Examination of Organization-Information System Fit from Perspectives of Technical Fit and User Fit

Information systems have evolved into ubiquitous, Web-based technologies that eliminate the boundaries of time and space, and support higher levels of social interaction. In order to achieve the highest return from information systems, organizations must match the capabilities of technology with their environment. This research proposes a model of Organization-Information System Fit based on task-technology fit and theories of user acceptance. Organization-information system fit may be achieved by balancing technical fit and user fit. Technical fit can be characterized as congruence among process-technology fit and task-technology fit. The idea of user fit is introduced as a moderator of the relationship between technical fit and utilization. Higher degrees of both technical fit and user fit should result in positive impacts on utilization and performance.

Comprehensive approach for informed life cycle-based materials selection

The choice of a particular material, for a certain product, to perform a certain function, is a task that is all too often jumped over, either because the choice looks obvious, or because habits of convergent thinking lead the engineering designer to persist in the most usual material for the application. Done in the early stages of product development, the choice of materials involves complex decision-making processes, balancing intricate functional, technological and economic criteria reflecting the function of the part/product, the manufacturing process and the production volumes and final cost. Development teams rely on some basic methods to decide on materials using engineering properties as benchmarks, but such methods seldom address the whole problem of material-function-shape-process-cost-environmental impacts.This paper starts with an overview of the existing methods for selecting materials and then moves onto propose a new selection procedure (Materials Selection Engine) that overcomes some of the limitations found in the former methods. It uses the materials engineering properties to accommodate their technical fitness, but also considers life cycle cost items and environmental impacts to create a decision space in which the best materials for the application are mapped and classified. According to the importance the design team wants to give to economics and environment issues and to upstream and downstream life phases more informed decisions can then be made. A case study is presented aiming at a better understanding of the procedure proposed.
