Fruit and vegetable harvesting robots have been widely studied and developed in recent years to reduce the cost of harvesting tasks such as labor and time. However, harvesting robots have many challenges due to the difficulty and uncertainty of task. In this paper, we characterize the crop environment related to the harvesting robot and analyzes state-of-the-art of the harvesting robot especially, in the viewpoint of robotic end-effector. The end-effector, an one of most important element of the harvesting robot, was classified into gripper and harvesting module, which were reviewed in more detail. Performance measures for the evaluation of harvesting robot such as test, detachment success, harvest success, and cycle time were also introduced. Furthermore, we discuss the current limitations of the harvesting robot and challenges and directions for future research.

With wide recognition of significant roles of venture companies in economic and industrial developments, substantial academic attention has been paid to understanding venture success and numerous policy measures have been made to help them. A serious problem, however, is that only a few limited number of venture could successfully grow to be large firm. The goal of this paper is to identify critical factors to drive 'leapfrogging' growth of venture companies by analyzing the success cases in Daejeon area. The theoretical analysis and case study suggest 1) founders' entrepreneurship continuity as a significant internal organization factor for growth and highlight importance of 2) exploring foreign markets and globalization of business operation in the early stage of growth. Furthermore, the research results identify two critical innovation strategies, 3) ambidextrous R&D strategy and 4) open innovation strategy, for entrepreneurial founders to effectively catch the business chances brought by environment change.

In the performance domain, physical performance is a measure that represents some degree of system, subsystem, component or device success in a continuous sense, as opposed to a classical binomial sense (success or failure). If applicable sensing and monitoring means exist, physical performance can be observed over time, along with explanatory variables or covariables. Performance-based reliability represents the probability that performance will remain satisfactory over a finite period of time or usage cycles in the future when a performance critical limit (which represents an appropriate definition of failure in terms of performance) is set at a fixed level, based on application requirements. In the case of inadequate knowledge of the failure mechanics, this physical based empirical modeling concept along with performance degradation knowledge can serve as an important analysis tool in reliability work in product and process improvement.

The purpose of this study is to explain changes in the mode of labor brought abut with the advance of information society and to suggest policies for the success of teleworking. It is likely that more and more people in advanced countries will be involved in some form of teleworking office workers use computers for handling dat, which is then transmitted over a telecommunications like to client or employer located some distance away. Though teleworking is becoming populer rapidly, it still has many problems to solve. In the conclusion, the paper suggests some measures to be taken for a successful teleworking system. (1) The first step is to establish a special team for the teleworking pilot. And probably the telework center will be most useful type for the pilot. (2) Some protections for teleworkers should be designed against discrimination in employment and occupation. (3) Some institutional arrangements such as tax benefits and incentive system are required for the success of teleworking system. (4) Maintaining competitiveness-faster services and lower cost-should be the first priority. (5) There should be a retraining and education system in the national level for the teleworkers to learn new IT applications.

Despite the rise of importance of Facility Management(FM), relatively little attention was paid to evaluate FM efficiency and drive for greater FM efficiency. The purpose of the present paper is to offer a quantitative analysis of 14 Key Success Factors(KSF) and 22 detailed maintenance practices in order to develop FM evaluation system. In addition, from survey with Owner/Property Manager group and Facility Manager group, the present paper measures both importance of detailed maintenance practices and performance satisfaction. It is expected that by using the result of this survey, this paper helps increase efficiency in FM. Moreover, It is expected that this paper will be used as base line data in developing FM practice evaluation system.

The discipline of software performance is very broad; it influences all aspects of the software development lifecycle, including architecture, design, deployment, integration, management, evolution and servicing. Thus, the complexity of software is an important aspect of development and maintenance activities. Much research has been dedicated to defining different software measures that capture what software complexity is. In most cases, the description of complexity is given to humans in forms of numbers. These quantitative measures reflect human-seen complexity with different levels of success. Software complexity growth has been recognized to be beyond human control. In this paper, we have focused our discussion on the increasing software complexity and the issue with the problems being faced in managing this complexity. This increasing complexity in turn affects the software productivity, which is declining with increase in its complexity.

Usability has become a primary factor in determining the acceptability and consequent success of consumer product. It is common that the product usability is evaluated by objective performance measures and/or subjective user preference measures. This study is concerned with objective evaluation of the product usability using 3-dimensional motion analysis. We evaluated car-audio position using 3-dimensional motion analysis. The parameters investigated in this experiment were height of car-audio, left-right angle, and front-end angle. The experimental results showed that the usability evaluation method using motion analysis was consistent with user's subjective assessment. This objective method can be applied to not only car-audio position evaluation but also various consumer products'usability evaluation.

The purpose of this study was to compare gifted and non-gifted high school students on their perceptions of success, grit, aspirations, and achievement goal orientation. Of the 550 high school students surveyed from 4 high schools (i.e., two schools for gifted, two school for non-gifted) in three metropolitan cities, Korea, 496 (i.e., 153 gifted and 343 non-gifted) completed and returned the questionnaire yielding a total response rate of 90.18%. Measures of students' grit (i.e., consistency of interest, and perseverance of effort), aspirations (i.e., intrinsic aspirations - physical fitness, self-growth, affiliation, community contribution, and extrinsic aspirations - financial success, image, fame), achievement goal orientation (i.e., mastery, performance approach and performance avoidance), and perceptions of success (i.e., Success in life is pretty much determined by forces outside our control.) were administered. It was found that the majority of gifted students and non-gifted students perceived that "success is outside our control.", and chose 'hard-working' as the most influential factor on their success. 60.4% of non-gifted students chose 'wealthy family background' as the other most influential factor, whereas only 48.2% of gifted did. Gifted students had higher 'consistency of interest' and 'mastery goals' than non-gifted students. Hierarchical multiple regression analyses showed that grit (i.e., perseverance of effort) was the crucial contributors for enhancing both gifted and non-gifted students' mastery goals and performance approach goals. Results are discussed in relation to theoretical implications and school settings.
