This study was performed to investigate the validity of food photographs for estimating individuals' dietary intakes and compare it with other dietary assessment methods. Subjects were 7 professors, 2 researchers, 12 dietitian and 16 graduate students majoring in food and nutrition. Among the subjects, 20 subjects had research experiences in the dietary intake survey more than one year while 17 had not. Each subject estimated 50 food portions displayed in computer monitor by comparing with standard food photographs, which were weighed portions of 28 foods from typical Korean diet. No significant differences between the estimated value and the weighed value of 17 (34%) food portions were shown in research-experienced group and those of 14 (28%) food portions were shown in no-researchexperienced group. 24-hour recall was the most frequently-used method for dietary assessment followed by in the order of food frequency questionnaire, dietary record, diet history and weighing method. After estimating food portions by photographs, 30 subjects (81%) were willing to use the method for dietary assessment because of its convenience and easy communication between researcher and subject. This study suggests that digital photography method would be a useful and convenient new instrument for estimating individuals' dietary intake. However, it is necessary to create standard database for food portions and carry out systematic education for food estimation in order to apply this method in the fields.

In order to analyze big data, documents should be converted to a open standard format to increase machine readability. It also need natural language processing tools. This study focused on the background of intelligent document processing and the status of research in the public sector, and predicted the changes in work that intelligent document processing would bring. This study noted the changes that intelligent document processing would bring to the archival work, and also considered changes in the role of archivist and their required competencies. Changes in archival work could be anticipated across a wide range of Records Management work and Archives Management work. In particular, it was expected to have a significant impact on the automation of repetitive archival tasks or the description and utilization of records. This study proposed the need to prepare new archival work procedures, methods, and necessary competencies in response to these change in archival work.

With the development in the IT industry and the growth in the game industry, user's game data is recorded in seconds according to various plays and options, and a vast amount of game data can be analyzed based on Bigdata. Combined with business, Bigdata is used to discover new values for profit creation in various fields, but it is utilized in the game industry in insufficient ways. In this study, considering the characteristics of the subdivided lines, we constructed a win-loss prediction model for each line using the game data of League of Legends, and derived the importance of variables. This study can contribute to planning of strategies for general game users to get information about team members in advance and increase the win rate by using the record search sites.

Numerous Sundials were fabricated during the reign of King Sejong of the Joseon Dynasty. One among them is Jeongnam-Ilgu (the Fixing-South Sundial), where the time can be measured after setting up the suitable meridian line without a compass. We reconstructed the new Jeongnam-Ilgu model based on the records of 'Description of Making the Royal Observatory Ganui (簡儀臺記)' in the Veritable Record of King Sejong. Jeongnam-Ilgu has a summer solstice half-ring under a horizontal ring which is fixed to two pillars in the north and south, and in which a declination ring rotates around the polar axis. In our model, the polar axis matches the altitude of Hanyang (that is Seoul). There are two merits if the model is designed to install the polar axis in the way that enters both the north and south poles and rotates in them: One is that it is possible to fix the polar axis to the declination ring together with the cross-strut. The other is that a twig for hanging weights can be protruded on the North Pole. The declination ring is supposed to be 178 mm in diameter and is carved on the scale of the celestial-circumference degrees on the ring's surface, where a degree scale can be divided into four equal parts through the diagonal lines. In addition, the time's graduation that is drawn on the summer solstice half-ring makes it possible to measure the daytime throughout the year. An observational property of Jeongnam-Ilgu is that a solar image can be obtained using a pin-hole. The position cast by the solar image between hour circles makes a time measurement. We hope our study will contribute to the restoration of Jeongnam-Ilgu.

While academic discussions and methodological researches on oral history are being progressed in Korea, its exploitation has already begun to increase with a variety of methods and approaches in the private sector. Oral history is a new method of research, as well as another process of production of archives. In order to make valuable and highly qualified archives of oral history with the application of the aforementioned conditions and characteristics, its recognition, environment, process, and method should be improved and developed. From this point of view, it is regarded as reasonable that oral history is recognized as a part of the strategy for documentation. Oral history should be produced based on common sense and reasonable judgment, applying empirical know-how rather than logic or principles because it holds a great number of characteristics, which include variable elements in the field of oral history. In addition, its process or documentation methods should be improved and developed, giving consideration to thorough exploitation. The promotion or revitalization of oral history is a signal that announces the advent of new archives and the new subjects of history at the same time. Endeavors to produce highly efficient archives of oral history are expected to be continued with the complex accumulation of empirical assets achieved at academic discussions and its fields.

The advent of e-government following the information revolution has affected public records systems. Records management should now be changed into an environment for establishing a national records management system based on the Internet of things (IoT), cloud, big data, and mobile (ICBM), and it is time to make a fresh start toward a next-generation records management system that responds to changes in the environment. Ultimately, it is time for a records management system that ensures a proper way of dealing with new environmental changes. It has been nearly 20 years since the Public Records Management Act was enacted in 1999, and its complete amendment was made in 2006 so that electronic records could be efficiently managed. When recompliance management needs to be rechecked, a full redesign is required to enable the current legal system to respond to the new circumstances in the present day. Therefore, this study is intended to suggest ways to improve the new records management legal system as the environment changes over the next generation and lay the legal groundwork for innovation in the national records management system.

In this paper, we propose a new indexing technique to solve various queries which have a strong good point not only database indexing schema take advantage of converting from semi-structured data to structured data but also performance is more faster than before. We represent structure information of XML document between nodes of tree that additional numbering information which can be bit-stream without modified structure of XML tree. And, We add in indexing schema searching incidental structure information in the process. In Querying schema, we recover ancestor nodes through give information of node using indexing schema in complete path query expression as well as relative path query expression. Therefore, it takes advantage of making derivative query expression with given query. In this process, we recognize that indexing and querying schema can get searched result set faster and more accurate. Because response time is become shorter by bit operating, when query occur and it just needs information of record set earch node in database.

The marine brown algal genus Colpomenia has a worldwide distribution, with five species reported in Korea and Japan. However, no studies to date attempted to identify the number of species and geographical distribution of Colpomenia along Chinese coast. To fill the biodiversity knowledge gap, we analyzed 63 mitochondrial cox3 and 62 mitochondrial atp6 sequences of Colpomenia specimens collected from 30 localities along the Chinese coast. Maximum likelihood and Bayesian inference trees suggest the presence of at least three Colpomenia species (i.e., C. peregrina, C. claytoniae, and C. sinuosa) in China. C. peregrina and C. claytoniae are documented for the first time. C. sinuosa was only found in the South China Sea and its distribution didn't overlap with that of C. peregrina which was found in the Yellow-Bohai Sea and the East China Sea. C. claytoniae appears to be confined to three isolated islands in the East and the South China Sea, where it occurs in sympatry with, respectively, C. peregrina and C. sinuosa. Future study can focus on comparing eco-physiological differences of Colpomenia species in response to environmental variables and exploring possible genetic hybridization / introgression at inter-specific contact zones.

The NIOSH health hazard evaluation program (HHE program) was created in response to the mandate to determine the toxic effect and potential health hazard of workplace exposure, which is found in Occupational Safety and Health Act of 1970 and the Federal Mine Safety and Health Act of 1977, A primary benefit of HHE program is its ability to provide current health hazard data to employers and employees, which assists them in identifying solutions to occupational health and safety problems in their workplaces, The HHE program also stimulates research in the development and review of sampling methods and diagnostic tests and may prompt additional exposure assesment efforts and toxicological and epidemiological studies. HHE projects also provide human exposure-toxicity data that are used to asses the validity of existing occupational health standards and to support criteria for new standards of recommendation, The HHE request is classified into four categories: 1) category 1: As a administratively invalid, 2) category 2: These are valid requests for which a site visit is not essential to an appropriate response, 3) Category 3 : These are valid requests for which a site visit is necessary for an adequate evaluation, 4) These are valid request which present a complex problem or an opportunity for research, To carry out HHE program one or methods of investigation might be used: 1) direct observation and evaluation of production processes and employee work practices 2) employees exposure level and air contamination level 3) medical test or physical examinations of employees 4) private, confidential interviews with employees 5) review of employer's record of injuries and illness, employee exposure data, medical tests and job histories. After investigation and analysing the data, NIOSH issues a final report, giving finding and recommendation.

The small/medium sized firms have big part and affect a national economy in the world. They underestimated in market until now make big change by standing out in international market. The Korean small/medium sized firms also get out of a domestic market stagnated and try to make inroads into international market. Especially, the Korean small/medium sized construction firms have very huge potentiality in international market globalized rapidly. But, the role of these firms actually have been insignificant in international market until now. This paper tried to present the alternatives to revitalize the overseas expansion of the Korean small/medium sized construction firms which have the potentiality. It analyzed the international contract trend of advanced construction firms to classify each group by using ENR data from 1996 to 2005, and presented the new standard of the Korean small/medium sized construction firms according to international contract portion, data, and legal bases. Finally, it used the expert interview method to refer to the revitalization of making inroads into international market.
