In real time applications, due to their effective cost and small size, wireless networks play an important role in receiving particular data and transmitting it to a base station for analysis, a process that can be easily deployed. Due to various internal and external factors, networks can change dynamically, which impacts the localisation of nodes, delays, routing mechanisms, geographical coverage, cross-layer design, the quality of links, fault detection, and quality of service, among others. Conventional methods were programmed, for static networks which made it difficult for networks to respond dynamically. Here, machine learning strategies can be applied for dynamic networks effecting self-learning and developing tools to react quickly and efficiently, with less human intervention and reprogramming. In this paper, we present a wireless networks survey based on different machine learning algorithms and network lifetime parameters, and include the advantages and drawbacks of such a system. Furthermore, we present learning algorithms and techniques for congestion, synchronisation, energy harvesting, and for scheduling mobile sinks. Finally, we present a statistical evaluation of the survey, the motive for choosing specific techniques to deal with wireless network problems, and a brief discussion on the challenges inherent in this area of research.

The purpose of this study is to investigate, analyze the purchasing behavior of fashion goods according to life style and role model of preteen generation, and provide manager or marketing planner for the reference data so that they can understand preteen generation and make proper strategy efficiently. So called, preteen market focusing on 1014 generation (from ten to fourteen years old) is highlighted. This generation created between the year 1989 to 1993 after Seoul Olympic monopolize parent's love in abundant economic environment and rise to the core of consumption subject. Products aiming at this preteen generation continuously though consumption mind was shrunk greatly due to recession. Only 2~3 years before preteen market was regarded as grey zone which doesn't belong to not only children (between six and nine years old) but also teenagers (between fifteen to eighteen years old). But in recent day their purchasing powers have increased rapidly and age group is divided on details, so that preteen market has become a niche market. Subjects were 333 persons consisting of students in the 4th~6th grade of primary school and the 1st~2nd grade of middle school in Daegu city. Measuring instruments are as follows: 5questions to differentiate preteen generation, 22 questions to measure life style, 17questions (which have six sub-factors such as purchase motive, factor of product selection, utilization of informant, purchase time, purchase place, and purchase method) to measure the purchase behavior of fashion goods measurement, and 16 questions (which have four sub-factors such as parent, entertainer & sports stars, brothers and sisters, friends) to measure model of role. Statistical data were processed by SPSS 10.0 programs. Frequencies, Factor analysis, Cluster analysis, ANOVA, Cross analysis, Multiplex regression analysis, and Duncan's multiple range test were carried out.

정보산업이 발전함에 따라 전략적 동맹과 인수합병은 매우 중요한 전략적 의사결정으로 인식되어 왔다. 이러한 중요성에도 불구하고 전략적 동맹과 인수합병 가운데 어떤 지배구조를 선택해야 보다 높은 기업성과를 도출할 수 있는가에 대한 연구는 매우 미미하였다. 본 연구에서는 전략적 동맹과 인수합병 선택에 영향을 미치는 주요 지식자원의 유형을 도출하고 이들 지식자원 간의 상호보완성 구조가 어떻게 전략적 동맹과 인수합병 선택에 영향을 미치는가를 분석하였다. 본 연구는 학문적 관점에서 보면 지식자원 간의 상호보완성 구조 파악 및 검정을 위한 새로운 방법론을 기반으로 지식자원의 유사성과 비유사성에 한정된 기존 연구의 한계를 극복 할 수 있는 새로운 연구 프레임웍과 방법론을 제시하였으며 이를 통해 지식경영 및 전략적 동맹과 인수합병 선택 연구에 일정 정도 기여를 하였다. 실무적 관점에서 보면 경영자로 하여금 전략적 동맹을 선택할 것인지 아니면 인수합병을 선택할 것인지에 대한 구체적인 의사결정 기준을 제공하였다는 점에서 그 의의가 있다.
