As more and more information is processed and stored in the digital form, many techniques and systems have been developed for service multimedia informations in wireless internet. In this paper, we propose MSPOB(Multimedia Statistics Post Office Box) structure for service datum which are related with similarity to subject a set of documents through grouping. The proposed structure is determined by relationship of datum based on count index and inverted file and is determined it through the semantic similarity between objects

From the extensive review of literature on existing precast prestressed concrete pavement (PPCP) systems, an innovative PPCP system has been developed. After the analysis and design, the sample system has been built and experimented under service loads and the defects of the system has been noted. Further study has been done to improve the performance of the defects. The appeared cracks around post-tensioning pockets was a crucial problem which needed to be solved in order to satisfy the service life of the system without any doubt. In this paper, different shape and arrangement of the post-tensioning pockets in the joint panel has been designed and analysed in order to find best performance for the system.

The purpose of this study was to investigate the infection situation of several diseases (post-weaning atrophic pigs) such as porcine reproductive and respiratory syndrome (PRRS) in swine breeding complex in Jeonbuk-Iksan. From February to October in 2006, a total of 28 swine samples (6-10 week old) were collected from 6 farms and examined by polymerase chain reaction(PCR) and clinical signs. In the rate of single infection, pneumonia was top (32.1%), followed by salmonellosis (14.2%)and Glasser's disease (10.7%) and double infection pneumonia/Glasser's disease (17.8%) was detected. PCR was detected of PCV 2 from 28 (100.0%) and PPV 6 (21.4%), PRRS PORF6 10 (35.7%) and POR7 11 (39.2%), but HC and AD was not detected. The results suggest that PCV 2 is complex infection PRRS, PPV and bacterial disease.

The purpose of this study was to analyze the activities of Community Health Nurse Practitionses using the Community Health Post Information System(CHPIS). The information system that have been introduced in 1994 and used by 400 Community Health Posts(CHPs) since 1997, which is about $20\%$ of the total CHPs nationwide. Twenty-five CHPs from two provinces participated in the analysis. Seventy-two percent of the CHPs among the participating CHPs started using the system since 1996. The degree of utilization of the information system was classified into three groups (i. e., high. medium, and low). The results revealed that only $48\%$ utilized the system with high level. The areas of analysis of the information system included characteristics of community residents, environmental attributes, and job analysis of Community Health Nurse Practitioners(CHNPs). The study results indicated that primary health care and drug demand and supply system showed the highest level of satisfaction in utilizing the information system by CHNPs.

IT convergence with agriculture is expected to bring more efficiency and quality improvement in pre-production stage, Production stage, post-production stage of agricultural products with the aid of information processing and autonomous control technologies of the IT area. This paper describes the actualized convergence service for agriculture, namely Smart Farming as a solution to cope various problems caused by severe conditions or the gap of viewpoints between the people engaged in farming and the IT engineers. In particular this defines service capabilities for Smart Farming, provides a reference model for Smart Farming, and identifies network capabilities required to produce an infrastructure which supports Smart Farming.

Occurrence of the oak wilt disease (Raffaelea sp.) was confirmed in 2004 for the first time in Korea. By using pictorial keys, morphological characteristics of Platypus koryoensis (Murayama), a vector for this disease in Korea, was compared to Platypus quercivorus (Murayama), a vector of oak wilt in Japan. Additionally, suggestions were made for the future research of the vector of oak wilt disease in the northeastern Asia.

Objectives: This study aimed to investigate the effects of auricular acupressure on fatigue and depression among patients undergoing chemotherapy for breast cancer. Methods: A nonequivalent control group nonsynchronized design was employed. Data were collected from December 2017 to May 2018, in the cancer center at a hospital located in B city. The experimental group received auricular acupressure four times a day, for 5 days, followed by a 2-day rest period. The control group received routine nursing care. The data were analyzed with independent t-tests, using the SPSS 21.0 program. Results: The level of fatigue and depression was lower in the experimental group as compared to that in the control group(t=5.29, p<.001; t=2.21, p=.038, respectively). However, depression scores increased post-intervention in the experimental group, as compared to the pre-intervention scores. Conclusions: The findings confirmed that auricular acupressure decreased fatigue however, depression scores increased post-intervention in the experimental group, as compared to the pre-intervention.

Many organizations seek statistical modelling facilitated by data analytics technologies for determining the prediction models associated with M&A (Merger and Acquisition). By combining these data analytics tool alongside with data collection approaches aids organizations towards M&A decision making, followed by achieving profitable insights as well. It promotes for better visibility, overall improvements and effective negotiation strategies for post-M&A integration. This paper explores on the impact of pre and post integration of M&A in a standard organizational setting via devising a suitable statistical model via employing techniques such as Naïve Bayes, K-nearest neighbour (KNN), and Decision Tree & Support Vector Machine (SVM).

This paper describes how to storing and querying trajectory information on PostgreSQL/PostGIS. Recently as technology of mobile devices is advancing, many researches for location-based services and moving object's trajectory have been studied. Trajectory is the set of information of the location by the time, and is one of the most im portant information for location-based services. Traditional spatial database systems do not support trajectory data types and functions. In this paper, we propose a trajectory data type and query functions for moving objects on PostgreSQL/PostGIS.
