Pneumoconiosis is one of the major problem in the field of occupational health at Korea. Therefore, the efficient diagnosis of pneumoconiosis is a hot issue on the occupational health program. The author executed this study to estimate the diagnostic value of high resolution computed tomography(HRCT) compared with chest radiography for screening of welder's lung. HRCT was introduced very recently for the diagnosis of pneumoconiosis, however, the diagnostic value for screening of welder's lung - principally nonfibrogenic and reversible - has not been evaluated. The subjects were fifty cases of welder's lung or suspected cases who had been collected between 1989 and 1994 from one shipyard and continuously followed-up on the basis of in-plant periodic health check program. We applied both chest radiography and HRCT on the same subjects from May 1 to 30, 1996. The images were evaluated by two careered radiologists independently. The findings of chest radiography were classified into four category by ILO classification, and the findings of HRCT according to the criteria of Bergin et al. The concordance between two radiologists expressed with Kendall's tau-b was 0.72 by chest radiography and 0.44 by HRCT- that is, interobserver variation of HRCT was bigger than that of chest radiography. The concordance between the two different methods was highly variable as 0.44 by radiologist A and 0.06 by radiologist B - that is, interobserver variation was very big. However, HRCT looked more detectable for the minor parenchymal change. These findings suggested that it is not appropriate to use HRCT routinely for screening of welder's lung due to lack of diagnostic criteria, and feasibility, acceptability and economic aspects. Nevertheless, HRCT might be recommendable in the case of equivocal parenchymal features on the chest radiography, unexplained respiratory symptoms, and/or lung function abnormalities suggestive of interstitial fibrosis.

The data which analyze the results of blood cultures are crucial basic information of the empirical therapy for patients with infection since the patterns of the species of microorganism isolated from blood and the results of antibiotic susceptibility test vary depending upon patients general features. Especially, in case of ESBL-producing bacteria, there is a close relation with use of antibiotics. Therefore, we carried out the research with the results of blood culture and antibiotic. 1. Total 39,305 cases of blood culture samples were investigated and positive patients of 2,216 (20.0%) were found. Among those, there were 40 patients with ESBL positive, and blood culture positive samples were 4,798 (12.2%). ESBL positive bacteria were found in 86 samples (including double checked culture bacteria). 2. The majority of ESBL producing bacteria were E. coli, K. pneumoniae and K. oxitoca as ordering based on the number. 3. The research showed the results that there were more females than male with the bacterias, more E. coli in over 50 years old aged group than other bacterias, more K. pneumoniae and K.oxitoca in less 1 year old aged group than other bacterias and largest numbers of patients with 13 patients (32.5%) in Chungcheongnam-do province were found. 4. The most common ESBL producing bacteria were E. coli throughout 3 years, but K, pneumoniae and K. oxitoca were also fairly found. Interestingly, E. coli was highly found in over 50 years old patients.

The purpose of this study is to investigate the effect of social factors and social stress with respect to alcohol consumption for university students and to provide basic data in efforts to develop educational method that teaches how to decrease alcohol consumption and deny demanding drinking. Questions concerning typical features and social stress from drinking were revised through 300 university students' self-recording surveys between April 8 and 9 in 2015. It consisted of 10 questions using a 4-point Likert scale. Moreover, the reliability of tool was Cronbach ${\alpha}=.82$. We used SPSS 18.0 and conducted frequency, ${\chi}^2$ and path analysis. If the frequency of drinking (B=.206, p<.001) gets low and the social stress from drinking is low (B=-.397, p<.001), the amount of drinking increases, particularly for men more than women (B=.169, p<.05). For women more than men (B=.274, p<.01), if monthly income is high (B=.178, p<.05) and stress from drinking is low (B=-.349, p<.01), the frequency of drinking is high. If the culture of practice in drinking has not formed voluntarily through education or publication, legal restriction that increases the cost of drinking has to be established, like smoking, to reduce the volume of drinking and promote moderation in drinking. The publication and education that teaches drinking leads to bad situations have to be conducted, much like the education programs involved for smoking. Also, discrimination of non-drinker has to be removed with the change of culture to reduce the stress by drinking.

Breast cancer is the most prevalent oncological disease among women. Various psychosocial distress is common at the diagnosis, treatment, and posttreatment phase of breast cancer. For the treatment of breast cancer, not only medical treatment but also psychosomatic integrative care will be needed. Patients with breast cancer may lead to increased vulnerability to stress, adjustment disorder, anxiety disorder, and depressive disorder, and these psychiatric diseases and conditions are associated with recurrence or exacerbation of breast cancer. Psychosocial treatment of anxiety and depression could increase the quality of life of patients and decrease the recurrence and progression of breast cancer. In this article, we reviewed 5 clinical breast cancer survivorship guidelines focused on psychosomatic integrative care including psychosocial treatment and alternative treatment for psychosocial distress. Because 5 treatment guidelines were using various definitions of evidence, we confirmed evidence of various psychosocial treatments for patients with breast cancer based on the definition of evidence by the US Preventive Service Task Force (USPSTF) guideline. We also reviewed the effect size of psychosocial treatment for anxiety, depression, mood, and quality of life in patients with breast cancer. This article discusses the barrier to the delivery of psychosomatic integrative care and suggests integrative care planning for breast cancer. Multi-disciplinary teams, patient's needs assessment, information technology support, patient and caregiver engagement, planned periodic monitoring of psychosocial distress by a psychosomatic specialist or consultation-liaison psychiatrist are recommended as key features of a psychosomatic integrated care plan.

Today the market of EDMS is esteemed more than 100 billions won. It signifies a comming of age of electronic records. The traditional archival theories which are based on the paper records are confronted with a new challenge. In some leading countries of archival studies reorientation of archives management has been tried by a number of distinguished specialists such as Bearman and Hedstrom since 10 years. As a consequence new paradigm of archival theories has been developed. Also in Korea this new paradigm has been introduced by some expert such as Lee, Sang-Min, Sul, Moon-won, Lee, Seung-Eok. However their arguments are too general to offer a concrete clue for new paradigm. Faced by new age of electronic records, it's important to start a discussion for the reasonable methods of electronic records management at once. The most drastically changed part of record management by the electronic technique is the life-cycle of records. The commonly practiced three-stage life-cycle is to be reduced to the two-stage life-cycle, and the concept of the spatial movement of records is to be changed. It can be also pointed that the public emerges as user from the early creating stage of records beyond time and space. Thus is can be said that the method of the management features dynamic and cohesive. The method of appraisal must be also changed and reproduced, so that it can reflect the various levels considering dynamics of the electronic records. Supposedly it will be a core factor that causes the change of methodology in records management with the change of life-cycle theory. It must be noted that various subjects would be involved in the work of classification and description over time and space and that feedback between them is of important. Description also tends to be made at the crating stage of records and structured dynamically. It results from the change of life-cycle and the introduction of the concept of continuum. Such trend allows us to start discussions on the assumption that description of both creator and archival professionals act together an important role. Of course, it is linked with the methodology in which most descriptions are made automatically at the early drafting stage of the structure. The meat date is formed on the assumption that there should be feedback between areas of automatic description, description of creators and archival professionals. The most important thing in description is to develop a suitable way how it is structured. An alternative must be offered for managing data set. As iweb that is being operated by Myongji university shows, records created in daily business are managed not as electronic records but as date base. This is because they exist outside the repository in the EDMS system. Since data set often has various sources, an alternative for classification needs to be developed. It is now likely that database is filed according to the created year to be transferred automatically to the repository. Over a long-term the total management of database, electronic records and electronic information will be a topic. A right direction of new paradigm will be found for both iweb and E-government, when practice and studies of theories are combined and interacted.

This study has researched and analyzed the relation among adolescents metabolic syndrome, dietary life, physical activity and mental health using $7^{th}$ National Nutrition Survey of $1^{st}$ year(2016) to provide the base data for the prevention of adolescent metabolic syndrome and the promotion of mental health. The subjects have been aimed at 13-18 year-old adolescents. The normal group consists of 201 males(56.4%) and 187 females(47.4%) and the adolescents with metabolic syndrome are composed of 9 males(56.4%) and 6 females(43.6%), totally 403 subjects. As a result of analyzing on the relation among adolescents' metabolic syndrome, dietary life, physical activity and mental health, the main influencing factors of metabolic syndrome are as follows. First, with regard to physical features, as BMI increases 1, the prevalence rate of metabolic syndrome multiplies 1.746 times. Second, when eating breakfast once to twice a week, the prevalence rate of metabolic syndrome decreases 0.87 times. Third, with regard to physical activity, as usual sitting hours a day increase 1 hour, the prevalence rate of metabolic syndrome multiplies 1.054 times. Fourth, the relation between metabolic syndrome and mental health of adolescents is not significant at all. Thus, the further study on metabolic syndrome focused on adolescents should be extended through the development of various variables of dietary life, physical activity and mental health focused on adolescents. In addition, the development of effective intervention program combining with dietary life, physical activity and mental health factors is necessary.

Purpose: The significance of neuroendocrine differentiation (NED) in gastric carcinoma (GC) is controversial, leading to ambiguous concepts in traditional classifications. This study aimed to determine the prognostic threshold of meaningful NED in GC and clarify its unclear features in existing classifications. Materials and Methods: Immunohistochemical staining for synaptophysin, chromogranin A, and neural cell adhesion molecule was performed for 945 GC specimens. Survival analysis was performed using the log-rank test and univariate/multivariate models with percentages of NED ($P_{NED}$) and demographic and clinicopathological parameters. Results: In total, 275 (29.1%) cases were immunoreactive to at least 1 neuroendocrine (NE) marker. GC-NED was more common in the upper third of the stomach. $P_{NED}$, and Borrmann's classification and tumor, lymph node, metastasis stages were independent prognostic factors. The cutoff $P_{NED}$ was 10%, beyond which patients had significantly worse outcomes, although the risk did not increase with higher $P_{NED}$. Tumors with ${\geq}10%$ NED tended to manifest as Borrmann type III lesion with mixed/diffuse morphology and poorer histological differentiation; the NE components in this population mainly grew in insulae/nests, which differed from the predominant growth pattern (glandular/acinar) in GC with <10% NED. Conclusions: GC with ${\geq}10%$ NED should be classified as a distinct subtype because of its worse prognosis, and more attention should be paid to the necessity of additional therapeutics for NE components.

Due to the trend toward computerization of business services in public sector and the push for e-government, the volume of records that are produced in electronic system and the types of records vary as well. Of those types, dataset is attracting everyone's attention because it is rapidly being supplied. Even though the administrative information system stipulated as an electronic record production system is increasing in number, as it is in blind spot for records management, the system can be superannuated or the records can be lost in case new system is developed. In addition, the system was designed not considering records management, it is managed in an unsatisfactory state because of not meeting the features and quality requirements as records management system. In the advanced countries, they recognized the importance of dataset and then managed the archives for dataset and carried out the project on management systems and a preservation formats for keeping data. Korea also is carrying out the researches on an dataset and individual administrative information systems, but the official scheme has not been established yet. In this study the items for managing archives which should be reflected when the administrative information system is designed was offered in two respects - an identification method and a quality requirement. The major directions for this system are as follows. First, as the dataset is a kind of an electronic record, it is necessary to reflect this factor from the design step prior to production. Second, the system should be established integrating the strategy for records management to the information strategy for the whole organization. In this study, based on such two directions the strategies to establish the identification for dataset in a frame to push e-government were suggested. The problem on the archiving steps including preservation format and the management procedures in dataset archive does not included in the research contents. In line with this, more researches on those contents as well as a variety of researches on dataset are expected to be more actively conducted.

This study examined relevant literature to review the concept of low-income class, its criteria and types. Based on the cases surveyed, the service status of public libraries for low-income class in South Korea was determined. Based on the findings of this study, we proposed new library services necessary for low-income class, such as the implementation of relevant programs aimed at resolving the digital information divide of low-income class, the introduction of employment programs for the self-economic-support for low-income class adults, and the introduction of reading and counseling therapy services. In addition, this study proposed five policies for activating library services for the low-income class: (1) To revise the act on library law so as to clarify the concept of low-income class, its criteria and types, (2) to revise the master plan for library development so as to bolster the library services for low-income class, (3) to conduct a national-level survey of the low-income class status and of the library service status, (4) to determine the actual features of the low-income class and their information demands, and (5) to prepare library services tailored to the diverse types of low-income class.

The paleogenetic analysis has become an increasingly important subject of archaeological, anthropological, biological as well as public interest. Recently, scientific research for human skeletal remains was more activated because of increasing awareness of the valuable archaeological information by the ancient DNA analysis. State of preservation of organic remains vary in different soil and burying environmental condition. Almost all available tissue disappear to analysis ancient DNA of bone in acidic soil caused by climate and geological features in Korea. Many preserved human remains excavated in the 'Heogwakmyo'(limelayered tomb of Chosun Dynasty Period) is able to explain through the relationship between burial conditions and bone survival form the burial method and ceremony. Ancient DNA analysis of excavated human bone form ancient tomb requires to remove contaminants such as microorganism's DNA and soil components that affect authentic results. Particularly, contamination control of contemporary human DNA is major serious problem and should verified by criteria of authenticity. In order to understand migration and culture of ancient population, when possible, ancient DNA studies needs to go abreast both radiocarbon and stable isotope studies because the dietary inferences will suggest ancient subsistence and settlement patterns. Also when the paleogenetic research supported with the arts and humanities research such as physical anthropology and archaeology, more valuable ancient genetic information is providing a unique results about evolutionary and population genetics studies to reconstruct the past.
