In the 21st century, maritime industry is the field, which play an important role in the improvement of human. Due to geographical conditions and the development of technology, the demanding of human can be solved easier by shipping. With the advantage of the location and the help of modern technology, maritime in dustry bring various advantage for HaiPhong. In this field in general or the job such as assistant, marketing and the contribution of women is undeniable. Meanwhile, with the field of shipping, there are some problems, which are preventing women from the work of seafaring. However, in the current, female employees are necessary in all the work, the thinking of the job for only male still exit in the brain of citizen. Therefore, the solutions for this problem need to set not only in maritime industry but also for the others heavy industry.

The rapidly improving price-performance of wireless technologies is providing an unprecedented platform for the development of wireless applications for the business. Such applications are able to take advantage of a new paradigm of mobility for data services, with the ability to sensitize to location, time and personal features. While big business has been a central feature of wireless implementation, it is now clear that small- and medium-sized enterprises (SMEs) are beginning to take advantage of the strategic benefits of wireless data communications. This study examines the state-of-the-art of wireless data services in New Zealand. It provides a survey of 127 current applications in use, as well as two short illustrative cases of application use. The paper rounds off with a summary and conclusions.

최근 스마트폰 사용자를 대상으로 다양한 종류의 어플리케이션이 개발/배포되고 있다. 특히 Google에서 개발한 안드로이드 운영체제인 경우 오픈 소스 정책을 채택하였으며 멀티태스킹 서비스를 지원함과 동시에 기존의 구글 서비스와 연계할 수 있다는 장점이 있다. 특히 안드로이드 운영체제에서 Layar, Wikitude, Sherpa 및 a2b 등과 같이 스마트폰 환경에서 GPS 위치정보를 이용한 어플리케이션이 개발되어 다양한 서비스를 제공하고 있다. 하지만 기존의 Cell-ID 기반의 위치정보는 이동통신사업자가 이동통신망에 설치한 교환장치를 통해 직접적으로 수집될 수 있기 때문에 개인 프라이버시 문제가 발생하고, 각종 사업자에 따라 얼마든지 정보가 유출될 가능성이 있는 정보이므로 개인 프라이버시 침해 위험성이 높다. 따라서 본 연구에서는 스마트폰에서의 GPS 기반 개인위치정보를 사용자 스스로 통제 및 접근제어할 수 있는 기술적 방안을 제시하였고 이를 설계하였다. 이를 통해 안드로이드 환경에서 다양한 GPS 개인위치정보 자기제어 SW 개발이 가능하였다.

The purpose of our this research, based on the Media Selection Theory, the Technology Acceptance Model, and the Social Influence Theory, is to investigate the influential factors that affect media selection in banking transactions. Analyses showed that for location sensitive bank window's and ATMs (automatic teller machines), defined as offline-based transaction channels, convenience was the variable affecting media selection. However, in the case of online media not related to location, (phone banking, internet banking, and mobile banking) reliability was the significant variable influencing use. The findings show that banking organizations may benefit from identifying traits of media affecting use, and should differentiate customer services for competitive advantage.

When a partial discharge takes place at the stator of a generator, the electrical pulse will propagate along the stator bars and the capacitor chains formed by the end part of the stator winds. On the first path, the pulse propagates as a travel wave at slow speed. On the second path, the pulse propagates at quick speed. Based on the data of the experiments on a real 50 MW steam generator, the author has found the pulses can propagate by magnetic field of the stator winding. It was studied that how to locating the partial discharge by signals coming from the different paths, including the features of signals on the two paths at time domain and frequency domain, the measurement frequency rang of the signals, the blind area, the advantage and disadvantage of this method.

Shortest path problems are among the most studied network flow optimization problems, with interesting applications in various fields. One such field is the route determination service, where various kinds of shortest path problems need to be solved in location-based service. Our research aim is to propose a route technique in real-time location-based service (LBS) environments according to user's route preferences such as shortest, fastest, easiest and so on. Turn costs modeling and computation are important procedures in route planning. We propose a new rest modeling method for turn costs which are traditionally attached to edges in a graph. Our proposed route determination technique also has an advantage that can provide service interoperability by implementing XML web service for the OpenLS route determination service specification.

A local damage identification method using measured structural static displacement is proposed in this study. Based on the residual force vector deduced from the static equilibrium equation, residual strain energy (RSE) is introduced, which can localize the damage in the element level. In the case of all the nodal displacements are used, the RSE can localize the true location of damage, while incomplete displacement measurements are used, some suspicious damaged elements can be found. A model updating method based on static displacement response sensitivity analysis is further utilized for accurate identification of damage location and extent. The proposed method is verified by two numerical examples. The results indicate that the proposed method is efficient for damage identification. The advantage of the proposed method is that only limited static displacement measurements are needed in the identification, thus it is easy for engineering application.

The travellers using social media leave their location history in the form of trajectories. These trajectories can be bridged for acquiring information, required for future recommendation for the future travelers, who are new to that location, providing all sort of information. In this paper, we propose a personalized travel path recommendation scheme based on social life log. By taking advantage of two kinds of social media such as travelogue and community contributed photos, the proposed scheme can not only be personalized to user's travel interest but also be able to recommend a travel path rather than individual Points of Interest (POIs). It also maps both user's and routes' textual descriptions to the topical package space to get user topical package model and route topical package model (i.e., topical interest, cost, time and season).

A robust damage detection method using short-time Fourier transform and beating phenomena is presented as an estimating tool of the healthiness of large structures. The present technique makes use of beating phenomena that manifest themselves when two signals of similar frequencies are added or subtracted. Unlike most existing methods based on vibration signals, the present approach does not require an analytic model for target structures. Furthermore, the main advantage of the proposed method compared to the competing diagnostic method using vibration data is its robustness. The proposed method is not affected by the amplitude of exciting signals and the location of exciting points. From a measuring view point. the location of sensing point have no influence on the performance of the present method. With a view to verifying the effectiveness of this method. a series of experiments are made and the results show its possibility as a robust damage diagnostic method.
