Purpose: Social media influencers (SMIs) have become significant sources of information influencing their followers' purchase intentions; few studies have been published on the effect of the number of followers and package tour prices on followers' purchase intention within the Vietnam travel industry utilizing naïve theories. This study examined the relationship between the number of followers and purchase intention and tested the moderating role of package tour price. Research Design, data and methodology: A 2 (number of followers: high vs. medium) × 2 (package tour price: high vs. low) between-subjects factorial design was used. 395 Vietnamese students (114 men, 281 women; M_age = 19.99, SD_age = 1.25) from Thuongmai University participated in the study. ANOVA and PROCESS MARCO were used to test hypotheses. Results: Findings indicate that participants show a higher purchase intention for SMIs with a higher number of followers than those with a medium one. When the package tour price is high, participants with a medium number of followers show a greater purchase intention than those with a high one. Conclusion: This recommendsthat tourism managers collaborate with SMIs with a high number of followers when the package tour price is low and with SMIs with medium ones when the package tour price is high.

SIP(Session Initiation Protocol) 기반의 VoIP(Voice over IP) 시스템의 구성 요소에서 레지스트라(Registrar)는 사용자들의 Registration 정보들을 저장 및 관리하는 역할을 한다. 네트워크상에서 이 Registration 상태는 관리자의 정책 등에 따라 동적으로 변화하게 되므로 사용자는 변경는 상태 정보를 알 필요성이 생긴다. Registration Event Package는 UA(User Agent)가 Subscriber로서 Registration 상태의 변경에 대한 통지를 요청할 수 있고 알림(Notification)을 통해 얻을 수 있는 매커니즘를 제공한다. 본 논문에서는 SIP 환경에서 이러한 Registration Event Package를 구현하여 사용자가 동적으로 변화되는 Registration 상태 정보를 알림을 통해 받을 수 있도록 하였다.

Drone package delivery routing problem is realistic problem used to find efficient route of drone package delivery service. In this paper, we present an approach for solving drone routing problem for package delivery service using two different heuristics algorithms, genetic and nearest neighbor. We implement and analyze both heuristics algorithms for solving the problem efficiently with respect to cost and time. The respective experimental results show that for the range of customers 10 to 50 nearest neighbor and genetic algorithms can reduce the tour length on average by 34% and 40% respectively comparing to FIFO algorithm.

Zero energy building was attended for energy consumption minimization by the energy saving technology about building heating and cooling energy consumption and the renewable energy production facility. So the government has supported the zero energy building supply for decreasing green gas emissions. The study about inventory of zero energy building has many proceeding. That inventory need the information of material and equipment. So information of material and equipment about zero energy building must be included for the zero energy building realization. Actually the database of zero energy building inventory construction through the inventory established studies has difficult because the database need many information. In this study, author proposed the test methods and performance reference for upload at inventory. It was constructed to material - module - package. Also the author analyzed the construction of the technical package for zero energy building. The author separated performance category to the energy performance for energy analysis and other performance for confirmed the durability, stability and etc. This performance category proposed the table. The test methods of material and equipment in the passive package and active package proposed to the international standard and korea standard basically korea standard. Also the performance reference was proposed to korea legal standard and various standard by this study results. And the authors proposed the table of performance value, test methods, performance reference. By result of this study, the test methods and performance reference will be used the basic data for inventory of zero energy building.

이 연구는 프리저브드 플라워 패키지 디자인의 효율적 전개 여부를 평가하기 위해 조형 요소 뿐 아니라 제품 속성을 파악하여 접근하는 방향이 전제되어야 한다는 판단에서 시작되었다. 선행 연구를 기반으로 패키지 디자인의 구성 요건을 재정립하고, 제품 유형 분류 모형을 제안하였다. 패키지 디자인의 구성 원리는 6가지로 사용성, 심미성, 주목성, 독창성, 정체성, 상징성이며, 구성 요소는 크게 4가지 형태, 재질, 색상, 그래픽, 브랜드로 분류하였다. 제품 유형은 제품 정보 측면에서의 위험 지각과 제품 효익 측면에서의 사고 유형을 축으로 하여 4개 영역으로 구분하였다. 제품 유형 모형 영역별 대표 제품을 사례로 들어 패키지 디자인 구성 요소에서 발견되는 특징을 분석하여, 제품 유형에 따라 어떻게 디자인이 적용되어야 효과적이고 효율적인가에 대해 검토하였다. 이 모형에 대입해 프리저브드 플라워 패키지 디자인 전략적 방향성을 도출하였다. 최종적으로 연구용역으로 진행되어 제안된 평택시 프리저브드 플라워 브랜드 '프리저빌'의 패키지를 분석하여 한계점을 찾아보고 프리저브드 플라워라는 제품이 지향해야하는 패키지 디자인 관점을 제언하였다.

This study analyzes the relative importance of the introducing factors for the critical success factors in the implementation stage of the lifecycle of ERP system using Delphi technique and Analytic Hierarchy Process(AHP). In the 1st layer of the hierarchy, technical factor is evaluated as the most important factor among organizational, technical, and supplier factors. In the 2nd layer, choosing a proper ERP package is evaluated as the most important factor within 15 factors followed by process-oriented approach, technical suitability, minimized customization, integration and association of system with trading parter, association with legacy systems, and support and involvement of top management. As a result of this analysis enterprise should choose an ERP package that is suitable to its business environment, and make the best use of(take full advantage of) best practice that ERP package provides to optimize the existing business procedure or process(to approach the existing business procedure or process). This study also shows the range of customization of the features provided by the ERP package should be minimized.

This paper compares of mechanical tensile properties of 6 kinds of copper foil. The beam lead made with copper foil. Different from other package type such as plastic package, Chip Size Package has a reliability problem in beam lead rather than solder joint in board level. A new tensile loading system was developed using voice-coil actuator. The new tensile loading system has a load cell with maximum capacity of 20 N and a non-contact position measuring system based on the principle of capacitance micrometry with 0.1nm resolution for displacement measurement. Strain was calculated from the measured displacement using FE analysis. The comparison of mechanical properties helps designer of package to choose copper for ensuring reliability of beam lead in early stage of semiconductor development.

The vlda is an R (R Development Core team et al., 2011) package which provides functions for visualization of multidimensional longitudinal data. In particular, the R package vlda was developed to assist in producing a plot that more effectively expresses changes over time for two different types (long format and wide format) and uses a consistent calling scheme for longitudinal data. The main features of this package allow us to identify the relationship between categories and objects using an indicator matrix with object information, as well as to cluster objects. The R package vlda can be used to understand trends in observations over time in addition to identifying relative relationships at a simple visualization level. It also offers a new interactive implementation to perform additional interpretation, therefore it is useful for longitudinal data visual analysis. Due to the synergistic relationship between the existing VLDA plot and interactive features, the user is empowered by a refined observe the visual aspects of the VLDA plot layout. Furthermore, it allows the projection of supplementary information (supplementary objects and variables) that often occurs in longitudinal data of graphs. In this study, practical examples are provided to highlight the implemented methods of real applications.
