The purpose of this study is to understand the transition process of Korean architecture and urbanism from traditional state to modern state, by investigating the development of modern survey and the characteristics of survey drawings during the Great Han Empire (大韓帝國), the early modern Korea. The governmental efforts of the Great Han Empire to introduce a modern survey system named Gwangmu Land survey (光武量田事業) ended in failure. After the Russo-Japanese War (露日戰爭, 1904-1905), the Residency-General (統監府) held the hegemony of Korean Peninsula. It reintroduced a modern survey system for the survey of land and buildings all over the country and enforced the Land and Buildings Certification System (土地家屋證明制度). Since then, the land and buildings survey was propagated rapidly and the modern system for land use was gradually organized. With the progress of modern survey, the survey bureau of Cabinet (內閣) and Department of Royal Household (宮內府) created survey drawings that had some characteristics of colonialism. Takjibu (度支部) produced cadastral maps of major cities, with which the modern land system was developed. In addition, the Royal Property Bureau (帝室財産整理局) produced survey drawings of land and buildings owned by the Royal Household which were finally converted into modern facilities.

The family Melyridae Leach includes more than 300 genera and 6,000 species consisting of four subfamilies (Dasytinae, Malachiinae, Melyrinae, Rhadalinae). Members of the subfamily Malachiinae is distributed all over the world except for New Zealand and prefer warmer, arid or semi-arid regions. Among the malachiine genera, a genus Kuatunia Evers includes 17 species worldwide, mainly distributed in East Asia. In this study, the genus and its described species, Kuatunia oblongula (Kiesenwetter), is newly added to the Korean fauna. A diagnosis, habitus photographs, and illustrations of diagnostic characters are provided, with a key to species of the genus in East Asia.

By use of RS and GIS, the QuickBird image and geographic map were used for the survey of the foreshore resources of Shanghai. The image was processed and interpreted. The distribution maps of sea dike, foreshore, vegetation, soil, hydraulic structures, landscape, topography, and so on were extracted in manual classification. These data have been integrated into the information management system for the shoreline and foreshore. It plays an important role in the evolvement analysis of the shoreline and foreshore.

To enable effective notification and promotion of the food poisoning prevention, Ministry of Food and Drug Safety (MFDS) developed a mobile augmented reality (AR) game called 'Sik-Jung-Dok-Jop GO', and demonstrated the game at 11 events including Food Safety Day. At the events, we have conducted a field survey of people who have played the game, and evaluated the awareness change of the food poisoning before and after the game. The level of the respondents' awareness about the 3 methods of the food poisoning prevention has been increased by 53 percent after playing the game, the level of awareness about individual food poisoning micro-organism has been improved by 2.1 times. According to the survey, 95% at the respondents answered that the game helped them understand the food poisoning more, and 90% of the respondents said that they enjoyed the game. In conclusion, we believe that 'Sik-Jung-Dok-Jop GO' will be able to create various educative effects on prevention of food poisoning including causative foods, main symptoms, and other related knowledge when the game is widely applied to students in kindergartens, elementary, middle, and high schools.

In this paper, we consider the HB estimators of small area means with repeated survey. mao and Yu(1994) considered small area model with repeated survey data and proposed empirical best linear unbiased estimators. We propose a hierachical Bayes version of Rao and Yu by assigning prior distributions for unknown hyperparameters. We illustrate our HB estimator using very popular data in small area problem and then compare the results with the estimator of Census Bureau and other estimators previously proposed.

An understanding of the knowledges, attitudes and perceptions of different populations is key for public health policy makers. Here, a survey was performed on knowledge, attitudes, and perceptions about malaria diagnosis, prevention, control, and treatment. The 407 survey participants included both uninfected inhabitants and patients from 2 cities (Gimpo- and Paju-si) of Northern Gyeonggi-do, known as high-risk areas for vivax malaria. We used community-based study design and non-probability sampling method using the primary data. Association between variables were tested using χ²-tests. In general, the information on malaria reported by the participants in this study was unsystematic and included inaccurate details. The knowledge of malaria symptoms, identified as headache, chills and fever, was high, but the surveyed community lacks knowledge of the specific medications used for malaria treatment, with a large number of respondents having no knowledge of any form of medication. Survey questions with high correct answer rates included questions about easy treatment of malaria in Korea, the high daytime activity of malaria-borne mosquitoes, and the infection risk posed by outdoor activities. However, a large portion of the respondents was unable to provide simple medical and biological information about the disease. This study aimed to comprehensively evaluate the knowledge, attitude, and practical behavior of the surveyed community with respect to malaria and the implications reported here could be applicable to other malaria endemic areas in Korea.

This paper discusses transformation of the US population census since 1990 and its future prospects by mentioning the 2000 census experience and the 2010 census plans. First, it examines the recommendations written for the 2000 census by the Committee on National Statistics, National Research Council, such as introduction of statistical estimation, response rate improvement, long form improvement, adjustment in differential undercount by race/ethnicity, alternative census methods, collection of small-area statistics in non-census years, and census frame enhancement, and describes how the US Supreme Court decision of 1998 led the Census Bureau to fail in conducting the US version of One Number Census which uses statistical estimation by matching actual enumerations from the Census main survey and post-enumeration survey. Second, it examines one key element of the 2010 U. S. census, say, the separation of long form from short form and describes the main features of American Community Survey, a rolling census which replaces long-form component of the traditional US "Decennial Census" Another element is MAF/TIGER Enhancement Program which aims to improve enumeration accuracy in the traditional short-form census and help the Census Bureau introduce a mobile computer system as part of high-tech census operation. In this paper, it is pointed out that the separation of long form from short form is not an accidental one which results from the US Supreme Court decision, but the Census Bureau at this time in 2008 worries about the accuracy of enumeration because it has failed to develop a mobile computer system and will have to canvass 115 million households by paper and pencil by hiring 600 thousand temporary census workers.

The unrecorded fungus Galactomyces pseudocandidus de Hoog & M.T. Sm. was isolated and cultured from an introduced species, Procambarus clarkii, in Korea. Two related species, Galactomyces citri-aurantii and Geotrichum candidum, have been reported, but no other Galactomyces spp. have been found in Korea. In this study, we isolated G. pseudocandidus from the digestive tract of American crayfish using RGY (river water-glucose-yeast) medium and then compared the morphological and molecular characteristics of this species with those of related species. As a result, we confirmed that G. pseudocandidus is an unrecorded fungus in Korea, so we described and reported the cultural characteristics and microstructures, such as conidia.

The Agrobacterium tumefaciens mediated gene transfer is widely used to generate genetic transformation of plants and transient assay of temporal exogenous gene expression. Syringe infiltration system into tobacco (Nicotiana benthamiana) leaves is a powerful tool for transient expression of target protein to study protein localization, protein-protein binding and protein production. However, the protocol and technical information of transient gene expression, especially double strand RNA (dsRNA), in tobacco using Agrobacterium is not well known. Recently, dsRNA is crucial for insecticidal effect on destructive agronomic pest such as Corn rootworm. In this study, we investigated the factor influencing the dsRNA expression efficiency of syringe agro-infiltration in tobacco. To search the best combination for dsRNA transient expression in tobacco, applied two Agrobacterium cell lines and three plant vector systems. The efficiency of dsRNA expression has estimated by real-time PCR and digital PCR. As a result, pHellsgate12 vector constructs showed the most effective accumulation of dsRNA in the cell. These results indicated that the efficiency of dsRNA expression was depending on the kind of vector rather than Agrobacterium cells. In summary, the optimized combination of transient dsRNA expression system in tobacco might be useful to in vivo dsRNA expression for functional study and risk assessment of dsRNA.
