Objectives: The established theory that breast density is an independent predictor of breast cancer risk is based on studies targeting white women in the West. More Asian women than Western women have dense breasts, but the incidence of breast cancer is lower among Asian women. This meta-analysis investigated the association between breast density in mammography and breast cancer risk in Asian women. Methods: PubMed and Scopus were searched, and the final date of publication was set as December 31, 2015. The effect size in each article was calculated using the interval-collapse method. Summary effect sizes (sESs) and 95% confidence intervals (CIs) were calculated by conducting a meta-analysis applying a random effect model. To investigate the dose-response relationship, random effect dose-response meta-regression (RE-DRMR) was conducted. Results: Six analytical epidemiology studies in total were selected, including one cohort study and five case-control studies. A total of 17 datasets were constructed by type of breast density index and menopausal status. In analyzing the subgroups of premenopausal vs. postmenopausal women, the percent density (PD) index was confirmed to be associated with a significantly elevated risk for breast cancer (sES, 2.21; 95% CI, 1.52 to 3.21; $I^2=50.0%$). The RE-DRMR results showed that the risk of breast cancer increased 1.73 times for each 25% increase in PD in postmenopausal women (95% CI, 1.20 to 2.47). Conclusions: In Asian women, breast cancer risk increased with breast density measured using the PD index, regardless of menopausal status. We propose the further development of a breast cancer risk prediction model based on the application of PD in Asian women.

The study is to analysis of fire protection regulations for the nuclear power plants (NPP) in the United States, Japan, the UAE (United Arab Emirates), and Korea with the intention of exporting NPP to the UAE. Fire protection regulations for NPP for these countries permit the fire protection design and facilities in accordance with the evaluation of the potential fire hazards. However, in Korea, the NPP is a part of power generation facilities in Korea fire protection law, and the atomic energy act classifies them as the reactor and related nuclear facilities. The fire protection law and atomic energy act are different to the criteria for the fire protection of NPP. To maintain the leading position as a nuclear exporting country, the performance-based fire hazard analysis should be reasonably incorporated in the design of the fire protection system. It was suggested that the integrated requirements of the fire protection for NPP should be incorporated to the construction article for the fire protection facilities specified in paragraph 2 of Act II, being classified into the special objects to be protected against fire, which requires a performance-based design in order to incorporate the specific requirements for NPP.

In 1994, the International Maritime Organization (IMO) adopted the International Safety Management Code (ISM Code) as SOLAS convention to ensure the safe operation of ships and to protect marine environment from pollution In December 2002, the IMO adopted the International Ship and Port Facility Security Code (ISPS Code) in the Chapter XI-1 of SOLAS to ensure the security of ships, crew, cargo and port facility. With 1 July 2004 being the coming into effective date of ISPS Code, there is a sense of urgency among the shipping companies and port authorities to accomodate the ISPS Code. Although both the ISM Code and the ISPS Code are based on the management system concept introduced in the ISO 9001, two Codes pursue different objective. Accordingly, it is meaningful to compare and analyze the requirements of three standards. In this article, the backgrounds, principles and requirements of three standards are analyzed and presented to offer several suggestions on the establishment and implementation of security measures in compliance with the ISPS Code to the shipping industry in time.

We devise data conversion methods and implement schema mapping and conversion system based on the study on research paper metadata characteristics analysis. Data conversion in unified form from databases of various systems is necessary for big data analysis. Legacy data conversion systems have drawbacks of syntax dependent problem and inconvenience for use. The implemented system, which is specialized system for research paper metadata, has easy schema mapping interface and can convert data with various syntax. In addition to that, Recompiling of the system is not necessary even if new schema which is not preregistered in the system comes in. We proved its usefulness by usability evaluation.

The purpose of this study was to analyze the trends of Classification Studies in Korea from 205 research articles in five scholarly journals in Library and Information Science during the period 1986-2011. Individual article was analyzed in the aspects of specific research topics, research methodologies, data collection & analysis, and the characteristics of classification research was suggested. The amount of research paper has increased during the period and the focus of the study was on practical use and most of the papers were about new classification schedules or modification of current classification systems. Most of the papers were literature research and comparative research on classification systems by professors or graduate students. Top 9 authors in classification research were professors or lecturers and a few authors were computer science major. Therefore, various research topics, research methodologies and collaborations with other disciplines are necessary for future classification research.

The convergence of broadcasting & telecommunication is not a reality by itself, but recognized as a reality by the discourse which defines and explains it. It is the premise from which this article aims at studying how the discourse on the broadcasting-telecommunication convergence is formed, practised and transformed. This study compares the case of France with the case of Korea in order to show how the same discourse can engender different consequences and evolve in a different way in different socio-political situations. The discourse of the convergence was born as a scientific knowledge in the reports of the European Commission and OECD, and accepted as an important object generating social debates. Then, the discourse faces the resistance of pre-existent discourses in France, while it spreads without clash in South Korea. The French discourse results in a horizontal regulation of contents and networks, while the Korean discourse creates a unique regulator for both traditionally distinguished sectors. Finally, unlike France, the scientific discourse of the convergence in South Korea is transformed into even a political, imaginary or utopian discourse.

Temporomandibular disorders(TMD) have been defined as a collective term embracing a number of clinical problems that involve the temporomandibular joint, the masticatory muscles, and associated structures. Since Dr. Costen, an otolaryngologist, published his article in 1934 claiming that pain in and around the jaw and "related ear symptoms" improved with alteration of the bite, diagnosis and treatment of temporomandibular disorders(TMD) have been within the concept of occlusion. However most of the modern descriptions for TMD no longer include occlusal disorders within their domain. Despite this trend toward the exclusion of occlusal disorders from TMD domain, the historical linkages between TMD and occlusal therapy are still strong. Currently the most popular theories regarding TMD etiology are based on the biopsychosocial model. In the future, treatment modalities should be directed at the pathophysiological processes of joint and muscle pain as well as the psychosocial aspects of chronic pain.

A growing interest in management and treatment for patients with temporomandibular disorder(TMD) by many health workers, including oriental medicine doctors, physical therapists as well as dentists, have been noted in South Korea. Some of these health workers claim correlation between dental occlusion, TMD, and systemic symptoms such as tinnitus, dizziness, neck pain, myalgia, low back pain, posture and many other systemic symptoms and many controversial treatments are being carried out on bases of theories and reasons with no strong scientific evidence. This article is a result of preliminary study by authors in gathering scientific data on few of these various treatment modalities for TMD using MEDLINE data, internet and tutorials given by those who are using these TMD treatment methods. The modalities that had been searched are as follows; (1) Craniosacral mechanism (2) Osteopathy (3) Myodontics (4) Chirodontics (5) Dental Distress Syndrome and Quadrant Theorem. An outline of those theories will be introduced, and the contents in detail for respective theory will be reported in the following articles.

Objective : Positive psychotherapy is based on the premise that positive thoughts and satisfaction with life are determinants for improving the symptoms of depressive disorder. This article highlights the effectiveness of group positive psychotherapy on the elderly living alone with depressive disorder in Korea. Methods : A total of 25 Korean elderly living alone with depressive disorder participated in group positive psychotherapy. The participants completed the Hamilton rating scale for depression (HAMD) and the Positive Thinking Questionnaire (PTQ) before and after the group positive psychotherapy. Results : The HAMD and PTQ scores of the participants after the group positive psychotherapy were higher than before the psychotherapy. A correlation between the age of patients and improvement of symptoms after group positive psychotherapy was found : the older the patients were, the better the improvements were. Conclusion : The study shows that group positive psychotherapy in the elderly living alone is effective in improving the symptoms of depressive disorder. The participant's age was found to be a factor that affects the improvement of depressive disorder symptoms.
