Geometry PIG (Pipeline Inspection Gauge)는 배관 내에 삽입되어 내부를 흐르는 매체에 의해서 추진되는 장치로서 배관의 기하학적 형상을 파악하기 위해 사용된다. Geometry PIG는 여러 종류의 센서를 지니고 배관 내부를 주행 하면서 탑재된 저장장치에 빠른 샘플링 속도로 데이터를 저장하기 때문에 획득된 많은 양의 데이터를 분석하기 위한 가시화 기법이 필요하다. 본 논문에서는 데이터의 특성을 고려하여 다양한 가시화 기법들의 스키마를 정의하고, 이러한 가시화 기법들을 이용해 geometry PIG 데이터 분석을 위한 통합된 가시화 기법을 제안한다. 통합된 가시화 기법은 각 가시화 기법들을 사용자가 원하는 형태로 배치하며 사용자가 원하는 시점에서 데이터를 파악할 수 있도록 가시화 기법에 따른 동기화와 사용자 인터페이스를 지원한다.

Assessment of nutrient balance in region unit is important to make a decision on nutrient management in agriculture. In this study, the nutrient demand in arable land and nutrient supply from livestock manure and chemical fertilizer were estimated from pig-concentrated areas. Three regions (H, I and J) were selected on the basis of pig numbers per unit area of arable land. In H and I regions, nitrogen amount from pig manure occupied about 50% of total livestock manure. Nutrient supply was three times higher compared to the nutrient demand in each of 3 regions. Soil available phosphate of higher pig-populated area in regional unit was higher than less populated livestock area. Therefore, livestock manure-derived regional management and monitoring of soil nutrient contents is necessary for the minimization and improvement of nutrient surplus.

Pig organ is thought to be the most suitable nonhuman organ for xenotransplanstation. However, one of the major constraints to using pig organs for xenotransplantation is human natural antibody-mediated hyperacute rejection (HAR). Elimination of a(1,3) galactosyltransferase (GGTA1) from the pig is expected to be a solution to the problem of hyperacute rejection. Many efforts have made characterization of GGTA1 in structure and function, improvement in the technique of DNA transfection of somatic cells and advancement of the pig NT, a specific modification has been made to one copy of the GGTAl gene by Missouri group in 2002 To date because homozygousity of the genetic modification has been achieved in this gene, the role of gala(1,3) gal specific natural antibody in HAR and the efficacy of xenotransplantation in a nonhuman primate model will be addressed. Of other genes are found to be involved in rejection of pig donors by primates, the technology will be available to modify those genes so that rejection can be overcome.

These studies were carried out to investigate the effect of Insameumja water extract on the inhibitory contractile action of acetylcholine in guinea pig. The results of these studies were as follows; 1. Contractile force of acetylcholine from trachea smooth muscle in guinea pig was significantly inhibited by Insameumja. 2. Dose-response of acetylcholine pretreated Insameumja in guinea pig was not significantly changed. 3. Inhibitory contractile action of acetylcholine pretreated propranolol in guinea pig was decreased. 4. Inhibitory contractile action of acetylcholine pretreated indomethacin was significantly changed by Insameumja. 5. Inhibitory contractile action of acetylcholine pretreated methylene blue was not significantly changed by Insameumja.

We generated a transgenic male cloned pig which was derived from fibroblast of white Yucatan miniature pig. After 2 weeks of birth, umbilical hernia which was not easily reduced was identified. Considering the usefulness of cloned pig, surgical treatment for umbilical hernia correction was performed and a cloned pig has been maintained healthy. This is the first report and can be useful for the treatments of umbilical hernia of cloned piglets.

The geometry PIG provides pipeline operators with continuous measurement of pipe centerline coordinates, bend radius, displacement, and bending strain in a single pass through the pipeline. This study introduces the developed geometry PIG(Pipeline Inspection Gauge) which is used for geometry surveys. This tool is equipped with the several sensor systems. The Inertial Navigation System (INS) comprises angle rate gyros and linear accelerometers. The system measures the precise path of the PIG during its traverse of the pipeline. This system is also used to produce a detailed map of the lire, measure curvature. Odometers measure the PIG´s distance moved along the line and instantaneous speed during the PIG run. Caliper sensors measure pipeline ...

This study was conducted to develop pig-housings based on the forecasting models of swine production, the weather conditions, and so on in Korea. The Korean pig-housings were developed according to the following basis : 1. They should be suitable to domestic weather conditions. 2. They should be designed based on the forecasting models of swine production of farrow to finish operation among the forecasting models of swine production in Korea. 3. Proper environments should be offered to pigs according to the growth. 4. The environmental control, the treatment of swine wastewater, and so on should be interrelated. 5. Manual energy should be saved by effective arrangements of pig-housings. In the future, performance test of the Korean pig-housings and development of facility automation systems which are suitable to these should be accomplished.
