Today, there has been a decrease in international shipping because of the weakening in global economies. Therefore, shipowners are thinking more about Floating Production Storage and Offloading (FPSO), which can perform functions related to the transporting, storage, and tracking of crude oil from oil wells. Given the huge expense of these special ships, shipowners require workers who can solve problems quickly and secure sustainable production functions in this age of globalization. Furthermore, it is important to design, construct, and maintain facilities so that a ship remains in operation over a long term. This paper discusses a system that uses knowledge-based AR to help workers improve their understanding and deal with pipeline equipment problems safely. In addition, it displays a 3CAD model and status information for products to improve their recognition on the FPSO that they intend to inspect. At the same time, the system works quickly and offers solutions for dangerous circumstances or malfunctions. It thus helps to maintain the functionality of the FPSO throughout its life-cycle.

We have been setting in The age of Ubiquitous that people are able to connect networks whenever and wherever by developing network. We can take any classes anytime we want even right checking out the result of a test through the internet with the spread of networks. The development of net-works has created WBI(Web Based Instruction) which has covered the limit of conservative education for instance, there are some content differences whenever a teacher teaches for each class, it is hard to take a lesson after having a certain period, the process of the class is changed as time goes by and so on. As the study of WBI is actively being worked in this moment, a various of class models are showing and materializing. In WBI, the exiting Objective Checking Assessment is applicable, some of the Performance Assessment which inspects and judges students' actual performance is Working whereas teachers who actually give them points don't have a embodied Performance Assessment Program. In this paper, I will present a Performance Assessment to use conveniently Performance Assessment Program not just students carrying out Performance Assessment using the internet but also teachers dealing with actual administrative works.

The IT services industry is considered as the leading industry of the ubiquitous age that raises a nation's overall productivity and efficiency. Therefore, it is receiving increasing attention as the industry that can bring about economic takeoff and successful overseas market entrance for the next generation. In order to achieve successful development, the industry should be competitive and armed with strategies that well demonstrate the characteristics of IT services. Therefore, it is important to explore the competitive factors of the industry for its qualitative development from the perspectives of IT services industry policies and as well as IT services companies. This study categorized IT services into three types-system integration, IT consulting, and IT outsourcing- and then examined the competitive factors of each service type and their relationships with financial and non-financial performances. In conclusion, the current competitiveness of domestic IT services industry is attributed to institutions environment rather than its competitive advantages in technology, quality, know-how, and highly qualified human resources. In order to facilitate the sound growth of the IT industry and seek reasonable market competition, the environment that puts its priority on the improvement of institutions environment and the ability to carry out a project needs to be established. In all, this study can be utilized as an important knowledge for the establishment of polices to foster IT services industry and of strategies that raise competitiveness to maximize the performances of companies.

Prospective memory is memory for activities to be performed in the future, such as remembering to purchase a piece of fruit on the way home or remembering to give someone a telephone message. Due to the decrease in memory ability, the aged have difficulty in remembering the tasks they intended to perform in the future. Employing survey and experimental methods, we identified the UI requirements for enhancing prospective memory (PM) performance for the aged. The survey included subjective assessments of PM performance for the aged and their preferred usability components and PM-supporting systems in an ubiquitous computing environment. The experiment examined the effect of contextual cues on PM performance for the young and the aged. Practical implications of our results were discussed in the respects of PM-supporting UI design requirements for the aged.

We analyzed the clinical characteristics and outcome of ileocecal and small bowel intussusceptions (ICI and SBI) in the pediatric patients. From August 2003 to July 2010, 144 children with intussusception were included in this study. We retrospectively reviewed the clinical records and Imaging study findings. A total of 86 children with ICI and 58 children with SBI were diagnosed. Children with SBI were older than ICI ($36.6{\pm}24.6$ months vs. $24.2{\pm}21.6$ months, p=0.002). Typical symptoms such as irritability, abdominal mass, bloody stool were more frequent in ICI than SBI (p<0.05) patients. In the ICI group, intussusceptums were reduced with air reduction (84.5%), surgery (17.4%), and spontaneity (1.2%). All patients in the SBI group were reduced spontaneously. SBI occurred in older age and was reduced spontaneously more frequently than ICI. Conservative management with close observation with follow-up by ultrasonography is recommended for SBI.

Background: Pancreatic cancer is a distressing disease with a miserable prospects and early recognition remains a challenge due to ubiquitous symptomatic presentation, deep anatomical location, and aggressive etiology. False positives and problems in distinguishing pancreatitis from adenocarcinoma limit the use of CA 19-9 as both disorders can present with similar symptoms and share radiographic physiognomies. This study aimed to assess the relative increase in accuracy of diagnosing the patients with chronic pancreatitis, benign neoplasm of pancreas and adenocarcinomas with CA 19-9, haptoglobin, and serum amyloid A in comparison to CA 19-9 alone. Materials and Methods: This hospital based case control study was carried out in the Departments of Medicine and Biochemistry of Manipal Teaching Hospital, Pokhara, Nepal, between $1^{st}$ January 2010 and $31^{st}$ December 2011. The variables assessed were age, gender, serum CA19-9, serum haptoglobulin, serum Amyloid A. The data were analyzed using Excel 2003, R 2.8.0 Statistical Package for the Social Sciences (SPSS) for Windows Version 16.0 (SPSS Inc; Chicago, IL, USA) and the EPI Info 3.5.1 Windows Version. Results: Out of 197 cases of pancreatic disease, maximum number of assumed cases were of adenocarcinoma of pancreas (95). Number of males (59) were more than females (36) in assumed cases of adenocarcinoma of pancreas. The mean values of CA19-9 raised considerably in cases of chronic pancreatitis, benign neoplasm and adenocarcinoma of pancreas when compared to controls. The highest augmention in CA19-9 values were in cases of adenocarcinoma of pancreas. The p-value indicates that in cases of chronic pancreatitis, there was not significant increase in precision of diagnosis. Conclusions: These statistics established that haptoglobin and SAA are useful in discriminating cancer from benign conditions as well as healthy controls.

The objectives of this study were to confirm a location of the calpastatin (CAST) gene in chromosome 2 and to detect associations of genetic variations with economic traits in the porcine CAST gene as a candidate gene for growth and meat quality traits in pigs. Calpastatin is a specific endogenous inhibitor of calpains. The calpain protease system is ubiquitous, and is involved in numerous growth and metabolic processes. Three single nucleotide variations were identified within a 1.6 kb fragment of the porcine CAST gene and these polymorphisms were used for genetic linkage mapping. Linkage and QTL mapping were performed with the National Livestock Research Institute (NLRI) reference families using eight microsatellites and SNP makers in the CAST gene. The porcine CAST gene was mapped adjacent to the markers, SW395 and SW1695 on SSC2 with LOD scores of 15.32 and 8.50, respectively. According to the QTL mapping, a significant association was detected at 82 cM between SW395 and CAST-Hinf I for weight at the age of 30 weeks. In addition, an association study was performed with the $F_2$ animals of NLRI reference families for Hinf I, Msp I and Rsa I polymorphisms in the CAST gene. Two polymorphisms, CAST-Rsa I and CAST-Hinf I, showed significant correlation for growth traits at p<0.01 and p<0.05, respectively.

Saprophytic aspergillosis (aspergilloma), a potentially life-threatening disease from the colonization of lung cavities by the ubiquitous fungus Aspergillus fumigatus, has been of surgical concern. Twelve patients with symptomatic aspergilloma underwent operative procedures at Pusan national University Hospital between January 1, 1984 and August 31, 1994. The mean age of the patients was 38.8 years and nine of them had hemoptysis; in two it was massive and life-threatening. Wine of the patients had underlying causes of cavitary lung disease and tuberculosis was the most common cause. Lobectomy was the most commonly performed procedure (in six) . Several major complications including excessive bleeding (2), and pneumonia (2), and empyema with bronchopleural fistula (1) occurred .and one patient died (operative mortality=8.3%). There were no recurrent symptoms in any of the 11 operative survivors during the follow-up period. It is concluded that early, aggressive surgical intervention can provide definite cure in established aspergilloma, even with minimal symptoms.

Spotted cordierite occurs as the result of intrusion of Wolaksan Granite of Cretaceous age in the northern part of the Ogcheon Metamorphic Belt, forming a contact metamorphic zoning in accordance with the distance from the granite body: a cordierite-muscovite-biotite-quartz assemblage and the higher-temperature cordierite-biotite-quartz-(cummingtonite). These quartz-ubiquitous mineral assemblages identified in the cordierite spot seem to reflect Al-deficient condition of the protolith. TEM observations of textural relations between the cordierite and mica within the cordierite spot clearly reflect that cordierite was formed at the expense of micaceous matrix. A structure refinement of the poikiloblastic cordierite was performed by the Rietveld refinement method. Unit cell of the cordierite was determined to be as follows : lower-temperature type: a=17.1480(9)${\AA}$, b=9.7743(6)${\AA}$, c=9.3184(5)${\AA}$, V=1561.9(4)${\AA}$3, higher-temperature type: a=17.136(2)${\AA}$, b=9.751(1)${\AA}$, c=9.322(1)${\AA}$, V=1557.7(4)${\AA}$3. They show a remarkable difference in the unit cell dimension. The refinement results indicate that structural sites of lower-temperature cordierite are wholly occupied by appropriating ions. Compared to this, tetrahedral sites of the higher-temperature type exhibit an order/disorder ranging about 5-8% as the result of substitution between Si4+ and Al3+, except for T26 site occupied wholly by Al3+. These structural differences seem to be related to the formation temperatures of both cordierite types.
