This paper presents an efficient text categorization algorithm that generates high quality bigrams by using the information gain metric, combined with various frequency thresholds. The bigrams, along with unigrams, are then given as features to a Naive Bayes classifier. The experimental results suggest that the bigrams, while small in number, can substantially contribute to improving text categorization. Upon close examination of the results, we conclude that the algorithm is most successful in correctly classifying more positive documents, but may cause more negative documents to be classified incorrectly.

Occupational Dentistry was introduced in Korea about 70 years ago. During the colonial period occupied by Japan till 1945, there were few documents about industrial dentistry, furthermore most cases of occupational diseases and accidents might have been concealed intentionally by the colonial government. After being an independent country, several dentists made efforts to set up 'Preventive Dentistry for Workers' performing specific oral health surveys, even though which were stopped by Korean War. In 1960s' and 1970s', some investigations of oral status were carried out intermittently for specific small groups;white-collar workers, mentally retarded person, buddhist monks and crews of ocean liners. At the same time there was important study in Korean history of occupational dentistry, which was 'a comparison of the oral hygiene conditions in the female workers of a spinning factory at intervals of 30 years.' In 1980s', young researchers began to give attention to erosion of the teeth due to sulphuric acid in the acid-related industry and dental caries due to sugar and flour in the sweets industry. After being democratic labor union movement activated in 1987, hidden and suppressed occupational diseases under the military dictatorship were exposed and flushed in the newspapers. It was shocking for all people that 15-year old boy had been dead due to mercury intoxication after 3-month employment in 1988. In 1990s', the activity for studying oral status of workers in their workplaces was launched and 'Occupational Accidents and Diseases in Oral and Maxillofacial Field' was published. And also The Korean Association of Occupationl Dentistry was established. Oral health examination of workers at the time of employment and of workers exposed to 5 special chemicals at the time of routine special health examination was adopted in 1992, and epocally oral health examination was also included in periodic routine examination of workers' health in 1995. So, occupational dentistry in Korea should cope with the changing needs of working environment and the altering scheme of health examination.

< TABLE > tags in HTML documents are widely used for formatting layout of Web documents as well as for describing genuine tables with relational information. As a prerequisite for information extraction from the Web, this paper presents an efficient method for sophisticated table detection. The proposed method consists of two phases: preprocessing and attribute-value relations extraction. For the preprocessing where genuine or ungenuine tables are filtered out, appropriate rules are devised based on a careful examination of general characteristics of < TABLE > tags. The remaining is detected at the attribute-value relations extraction phase. Specifically, a value area is extracted and checked out whether there is a syntactic coherency Futhermore, the method looks for a semantic coherency between an attribute area and a value area of a table that may be inappropriate for the syntactic coherency checkup. Experimental results with 11,477 < TABLE > tags from 1,393 HTML documents show at the method has performed better compared with previous works, resulting in a precision of 97.54% and a recall of 99.22% in average.

The International Chamber of Commerce (ICC) eUCP came into force on 1 April 2002. The eUCP is a supplement to the current existing Uniform Customs and Practice for Documentary Credits (UCP500), which governs the use of electronic presentation. The eUCP is not a revision of the UCP. It is a supplement intended to deal with situations where presentations are made electronically. That is to say, the eUCP is a supplement to the UCP that, when used in conjunction with the UCP, will provide the necessary rules for the presentation of the electronic equivalents of paper documents under letters of credit. The purpose of this paper is to study on the criterion of examination of electronic records under the eUCP.

The personal health record platform can store and manage medical records, health-monitoring data such as blood pressure and blood sugar, and life logs generated from various wearable devices. It provides services such as international standard-based medical document management, data pattern analysis and an intelligent inference engine, and disease prediction and domain contents. This study aims to construct a foundation for the transmission of international standard-based medical documents by mapping the diagnosis items of a general health examination, special health examination, life logs, health data, and life habits with the international standard terminology systems. The results of mapping with international standard terminology systems show a high mapping rate of 95.6%, with 78.8% for LOINC, 10.3% for SNOMED, and 6.5% when mapped with both LOINC and SNOMED.

This study put the purpose to contribute in the way of complementing a qualification of the opened examination for the fire service to improvement of disposition and specialty of a firemen, and to development of a fire department. The subjects of the opened examination for the fire service are mostly same as those of general civil service examination, and they incite indiscreet competition. As a result, firemen morale became declining. On the basis of every kind of documents and data and the analysis of a questionnaire with students of the department of fire safety supervision, we should solve the problems of lack of qualification and professionality causing stress from work by the unit completion system, which qualifies those who complete prescribed unit in the opened examination for the fire service. It must promote the specialty of a fire fighter so that we can step up to the advanced fire department.

This study was conducted to find qualitative approaches to occupational reference to group health practices. In-depth interviewing was done on 8 subjects health monitor members, owners and occupational nurses, respectively). The major findings were as follows; 1. Visiting health management Useful services were 'health counseling', 'medical examination', 'providing informations about managing diseases', 'agency business in relation to Labour Ministry' and 'giving a recognition about occupational health service to owners'. Insufficiencies were 'lack of treatment service after medical examination' and 'lack of follow up services constantly'. 2. Occupational nursing service Useful services were 'providing health information' and 'counselling about health'. Major contents of occupational nursing services were 'management of occupational and adult diseases' and 'explanation of the results after medical examination'. Insufficiencies were 'deficiency of the place where group health education could be performed', 'lack of additional or closer examinations needed in counselling' and 'discontinuous selection of additional or more exact examinations'. 3. Health monitor members Health monitor members in industries were classified into two. Some were selected by owners and the others were selected simply by considering their administrative abilities such as proficient management of documents. Their major tasks were to connect workers with occupational health management agencies. This study suggests that programs should be developed which enable health monitor members to cooperate with occupational nurses.

YangDongChangHwaHuRok(兩東唱和後錄)is a book that organized the conversation between Joseon physician Ki-DuMun(奇斗文) and Japanese Acupuncture specialist Murakami Tanio(村上溪南) and others when they visited the quarters where the Choson Delegation(朝鮮通信使) were staying in, while the Choson Delegation party were visiting Japan in 1711. YangDongChangHwaHuRok(兩東唱和後錄) was discovered in the process of gathering medicine-related historical documents of the Choson Dynasty that is spread out all over the Japanese region, with the help from Japanese and Chinese scholars. This was part of the Co-Examination-Research-Process of korean medical documents that are located in the East Asia traditional medical region, which was promoted by the Korean Institute of Oriental Medicine in 2003. This paper has analyzed in-depth, with an inner-medical view, the academic exchange content of YangDongChangHwaHuRok(兩東唱和後錄) by following the order of the main text. With this examination, we were able discover new facts about the interest in Primary Symptom(是動病) and Secondary Symptom(所生病) of 17th century doctors, a new hypothesis on the diffusion of HeoYim(許任)'s ChimGuKyungHeomBang(鍼灸經驗方) in Japan, the existence of a new acupuncture tool called ChongChim(腫鍼), and the influence of the 18th comtemporay famous traditional medical books (it is called UiHakYipMun(醫學入門) and ShinEungKyung(神應經) on the 18th century East Asian medical circle. We were also able to ascertain the specific medical content that was diffused to the Japanese medical circle by the Korean medical circle.
