Through reviewing and comparing the current virtual shopping malls web sites integrated VR into E-commerce, this paper analyzed both the advantages and disadvantages of two kinds of methods for product presentation: 2D image based and 3D model based presentation method. Using the virtual shopping mall (EasyMall) as a showcase, we presented the architecture of the system and the development technologies, especially those in the mixed presentation method. The presentation and customization methods in the two related modules, including the PhoneShow for mobile phone and EasyShow for textile products, were discussed. It indicated that the integration of E-commerce with VR could provide consumers with virtual experience and intelligent service for business activities. Furthermore, the product presentation methods can be made available for use in different cases.

Visible light communication (VLC) is considered to be an attractive scheme to realize the broadband wireless communication for an indoor environment. We present a room division multiplexing (RDM) mechanism for an indoor multi-room VLC network, which utilizes the spatial position of the LED lamp in different rooms as a novel dimension of network resource for multiplexing, and thus the network capacity is increased. In such a network, the service interruption caused by user cross-room movement is an important problem, and we propose a double-area-positioning based cross-room switch solution. An experimental platform demonstrates the RDM-deployed VLC network, and validates the performance of the presented switch mechanism.

This study is caused by the urgent need to constantly fight against such a shameful phenomenon of society as corruption, the flourishing of which cannot be overlooked. This phenomenon has many negative manifestations and consequences, undermines the national security of the state, slows down the development of democracy, worsens the state of all spheres of life (economic, political, administrative, etc.), worsens relations with foreign partners, forms tolerance for corruption in the public consciousness. Today, the process of fighting corruption is extremely important for our country, because it depends on the independence, democracy, sustainability of Ukraine. However, there is a complex and ambiguous situation regarding this process, as there is a clear coordination of state policy in the fight against corruption, insufficient and narrow understanding of ways to combat it. There is a lack of efforts by the authorities to overcome corruption challenges and use ineffective means of combating them. Instead, corruption causes great material and moral damage to states as a whole and many of its citizens.

The aim of this project is to analyze the queueing model with the two types of customers which either can wait unrestrictedly or wait restrictively in the system depending on the condition of service facility unless they may be served immediately. This model consists of the three-dimensional state space and then quasi birth-death process is formulated. The steady-state probabilities and measures of performance of this system are derived by using Matrix Geometric method.

As the logistics industrial environment becomes more complex and its scale becomes increase, the vehicle fleet scheduling system has become recognized the necessity as a major strategy in the logistics field. The vehicle fleet scheduling system is computerized package that find the vehicle routes and schedules to accomplish the required service to customers using vehicles. This paper introduces the state of the art of vehicle fleet scheduling system in Korea and foreign country and the future research subject are presented.

The purpose of this study was to analysis on the current state of batterer intervention programs in South Korea. This study was composed of two parts. First, intervention programs for domestic violence batterer in foreign countries were reviewed. Second, bitterer programs in South Korea were explored. In order to expand these bitterer programs in South Korea, culturally appropriate intervention, more innovative research on comparison analysis of diverse intervention approaches, program impact, type of curriculum, and intervention protocol, evaluation criteria, requirements pertaining to program facilitators, political assistance, and coordinated community response and community service are strongly needed.

Vehicle fleet planning problem is generic name given to a whole class of practical decision making problems which find the vehicle routes and schedules to accomplish the reqired service to customers using vehicles. In this paper the various problems are classified into the three groups according to their characteristics: (1) vehicle routing problems, (2) vehicle scheduling problems, and (3) vehicle routing and scheduling problems. The State of the art of each group is described and the future research directions are presented.

본 연구는 서비스철학이 서비스시대 인류사회의 발전원리임을 입증하기 위해 수행되었다. 상호존중의 식물적 생태계가 서비스시대 인류사회 운영원리가 되어야함을 입증하려고 시도하였다. 고대부터 현대에 이르기까지 통시대적으로 서비스철학이 인류사회 발전 지혜임을 보여주려고 하였으며, 동양과 서양 등 모든 지구공간에서 서비스철학이 인류사회 발전 지혜였음을 입증하려고 시도하였다. 또한 지구상의 모든 공간과 인간의 모든 시간 위에서 명멸한 많은 국가와 개인들의 발전 지혜에도 서비스철학이 그 중심에 있었음을 입증하려고 시도하였다. 한편 서비스철학에 위배되는 운영을 한 많은 국가와 개인, 그리고 시간과 공간에서는 발전이 더디거나 쇠퇴가 빨랐음을 입증하려고 시도하였다. 국가들의 차이는 하드웨어가 아닌 소프트웨어에 있었음을 본 연구는 보여주었다. 더 구체적으로 정신과 문화 등 소프트웨어적인것의 중심에 서비스철학이 내재되어 있었던 국가들은 인류사회에 큰 기여를 한 것으로 분석되었다. 그리스 로마와 베네치아공화국, 네덜란드공화국, 곧이어 미국과 현대 대한민국 등의 사례가 이를 입증하고 있고, 소련 등이 이를 반증하고 있다고 볼 수 있다. 전자는 국가 운영 소프트웨어가 강한 사회였고, 후자는 하드웨어가 강한 사회였다고 할 수 있다. 시민들이 자율적으로 구성하고 운영해간 국가와 상층부 주도 운영 국가의 경우는 차이가 크다. 상층부 주도는 서비스철학에 기반하지 못하고 있기 때문에 축적되는 소프트웨어적 힘이 약해서 인류사회에 지혜 축적이 약했다고 할 수 있다. 따라서 그동안의 인류사회가 이기심이 주도하는 자기중심적 동물적 생태계의 사회였다면, 지금부터의 서비스시대 인류사회는 상호존중과 자기중심이 공존하는 식물적 생태계의 사회로 변화되어야 지속적인 발전이 가능하다고 할 수 있다. 과거 인류사회에서 서비스철학이 중심이 된 사회가 더 번영하고 더 큰 유산을 인류에게 남겼듯이, 앞으로의 서비스시대 인류사회는 서비스철학이 중심이 되는 식물적 생태계의 인류사회가 되어야 함을 제안하였다. 자기 중심 소아와 공동체 중심 대아가 변증법적인 과정을 통해 팽팽한 균형을 이루는 서비스철학 기반 사회가 인류사회의 발전 지혜임을 제시하였다. 향후 이에 관련되는 심층적인 추가 연구들이 필요하다.
