This study presents the development of pointcloud data integration technology in construction sites via drone photogrammetry and MMS LiDAR. The integration of pointcloud data from drones and MMS technology can provide precise and accurate 3D digital maps of construction sites, which can benefit the development of smart construction and BIM. The advantages of using both drones and MMS technology for pointcloud data acquisition in construction sites are discussed, along with the limitations and challenges of using drone photogrammetry and MMS LiDAR for pointcloud data integration. The results of this study can contribute to the advancement of pointcloud data integration technology in construction sites and improve the efficiency and accuracy of construction projects.

Knowledge integration is becoming a primary function of improving organizational capabilities and performance in today's convergence paradigm. The knowledge integration capability of employees has increasingly been regarded as a critical source for developing new products and services. This study investigates the influential factors of employees' knowledge integration capability and its effects. A theoretical research model was developed based on the socio-technical perspective and information processing theory. The model includes teamwork quality, expertise, IT support, and knowledge complexity as the primary influential factors of employees' knowledge integration capability. A large-scale survey was conducted for gathering data (a total of 316 samples from 141 organizations) to test the proposed model. The test results of the hypotheses show that expertise and knowledge complexity are the significant influential factors of employees' knowledge integration capability, and also the capability has a positive effect on the knowledge creation performance of employees. Our findings contribute to the development of initiatives for promoting employees' knowledge integration capability, especially in knowledge intensive organizations focusing on convergence products and services.

One of the most versatile approaches for analyzing the dynamic behavior of structural systems is direct time integration of semi-discrete equations of motion. However responses computed by time integration are generally inexact and hence the corresponding errors would rather be studied in advance. In spite of the various error estimation formulations that exist in the literature, it is accepted practice to repeat the analyses with smaller time steps, followed by a comparison between the results. In this paper, after a review of this simple method and disregarding the round-off errors, a more efficient, reliable and yet simple method for estimating errors and enhancing the accuracy is proposed. The main objectives of this research are more realistic error estimation based on the concept of convergence, approximately controlling the reliability by comparing the actual rate of convergence with the integration method's order of accuracy, and enhancement of reliability by applying Richardson's extrapolation. Starting from the errors at specific time instants, the study is then generalized to cases in which the errors should be estimated and decreased at specific events e.g. peak responses. Numerical study illustrates the efficacy of the proposed method.

This study aims to investigate what to be prepared and implemented for the military integration when South and North Korea are making progress toward unification. Although we can not exactly predict when the unification will be completed at this time, preparations for the military integration should be ready ahead of time. Since the failure of the military integration can threat the unification, elaborated and practical solutions are required. Therefore, the study tries to answer the following questions : 1) What types of the military integration are desirable and what are the prerequisites for the unification of Korean Peninsular? ; 2) What potential military tasks could be caused by military integration? ; 3) What are the core and major tasks among them and how could they be solved in practical aspects?

최근 건설분야에 화두가 되고 있는 건축정보모델링(BIM, Building Information Modeling)은 건설산업의 패러다임 전환을 통한 새로운 성장동력의 미래로 부각되고 있으며, 건축분야는 서울시, 용인시, LH공사 등 BIM을 활용한 공공 발주사례가 확산되는 추세다. 토목분야는 건축보다 기간이 길고 비용이 크며 이해당사자가 너무 다양해서 발생하는 정보의 양이 방대할 뿐만 아니라 활용분야를 다양화하지 못하고 이를 뒷받침해주는 제도나 지침의 부재 등으로 인해 건축분야보다 BIM도입이 늦어지고 있다. 이에 토목분야에서 활용할 수 있는 3차원 형상정보와 관련된 정보모델표준, 지침, 가이드를 개발하기 위해 BIM 적용시 가장 효과가 크고 도입의지가 강한 엔지니어링사의 BIM에 대한 인지도 분석을 통해 토목분야 BIM 도입을 위한 기초자료로 활용하고자 한다.

This Study aimed at suggesting the plan for accumulating and utilizing schedule information of IFC file in BIM-based delivery system. For this Propose, First, literature review is conducted for analyzing utilization plan of schedule information and the IFC standard. Second, Schedule Planning process is analyzed to draw Schedule elements, and schedule information items is derived by analyzing schedule process and commercial software. Also, schedule elements in the IFC schema is derived by analyzing IFC schema through drawn schedule information. Finally, this study suggests a concept model accumulating and utilizing Schedule information included in IFC schema, and a conceptual delivery process of BIM model by analyzing BIM Application Guideline for Facility Project by PPS (Public Procurement Service) for accumulating IFC delivery files This study will expects to contribute to accumulate information of BIM model at the point of nationally introducing BIM.

최근 정보화 산업이 고도화 되어 신속하고 다양한 통계정보에 대한 수요가 급증하고 있다. 그러나 기존 도로보수현황은 수기작성 및 e-Mail에 의한 자료 취합으로 집계의 신속성이 떨어지고, 자료 관리와 정보 제공을 위한 매체가 파일 및 책자로 국한되어 있어 효과적으로 활용되지 못하고 있다. 매년 발간하는 도로보수현황의 신속한 자료 취합, 통계자료의 시의성 확보 등 활용성 제고를 위해 도로보수현황 시스템 구축 연구를 진행하고 있다. 본 논문에서는 도로보수현황의 자료 관리 체계 개선을 바탕으로 WEB 기반의 도로보수현황 시스템 구축에 대해 기술하고자 한다.

There are two forms of medicine that have existed over time and are important in the delivery of expert health care. The forms of medicine are traditional and modern medicine. This study was aimed at assessing the awareness and perspective on the use and integration of traditional and modern medicine in a rural area of Sokoto State, Nigeria. Two hundred and seventy-one (271) respondents were recruited and a self-administered questionnaire on the awareness and perspective on use and integration of traditional and modern medicine was used to assess the participant's view. Among the participants, 200(73.8%) were females. The mean±SD age of respondents was 30.55±9.73 years. 80.8% of the respondents were aware of traditional medicine while 100% were aware of modern medicine. All respondents prefer modern medicine but about 28.8% support integration of both healthcare services. The results were considered significant when p-value was less than 0.005. There is a statistically significant relationship between the integration of traditional and modern forms of medicine and age, gender, religion, education, ethnicity and occupation but not for marital status. Though all the respondents preferred modern medicine to traditional medicine, some people still feel it will be good to combine both for a better healthcare system.

This study derives quality checking items in Building Mechanical Systems Design Criteria, and suggests quality criteria to review BIM models in the duct system of an air conditioning system for rule-based automatic checking. First, components for the duct system of an air conditioning system were reviewed, and the quality checking items were drawn from Building Mechanical Systems Design Criteria, through assessment according to object, attribute and relationship composing the BIM model. Second, quality checking types were derived, by analyzing the quality checking items and Rule set of the Solibri Model Checker. Finally, methods of algorithm functioning for checking the BIM models for mechanical systems in computers were drawn, and Elements to comprise the quality checking criteria (rule) were suggested. This study means that that checking items are derived from domestic criteria, and a way for the development process of determining quality checking criteria (rules) is suggested.
