Objectives : Our objective is to review and summarize the previous studies on the health effects of exposure to oil spills in order to make suggestions for mid- and long-term study plans regarding the health effects of the Hebei Spirit oil spill occured in Korea. Methods : We searched PubMed to systemically retrieve reports on the human health effects related to oil spill accidents. The papers' reference lists and reviews on the topic were searched as well. Results : We found 24 articles that examined seven oil spill accidents worldwide over the period from 1989 to August 2008, including the Exxon Valdes, Braer, Sea Empress, Erika, Nakhodka, Prestige and Tasman Spirit oil spills. Most of the studies applied cross-sectional and short-term follow-up study designs. The exposure level was measured by assessing the place of residence, using a questionnaire and environmental and personal monitoring. Studies on the acute or immediate health effects mainly focused on the subjective physical symptoms related to clean-up work or residential exposure. Late or mid-term follow-up studies were performed to investigate a range of health effects such as pulmonary function and endocrine, immunologic and genetic toxicity. The economic and social impact of the accidents resulted in the socio-psychological exposure and the psychosocial health effects. Conclusions : Studies of the health effects of exposure to oil spills should consider a range of health outcomes, including the physical and psychological effects, and the studies should be extended for a considerable period of time to study the long-term chronic health effects.

In this paper, a method to design 3-dimensional (3-D) cross-lattice signal constellations with increased compactness is presented and analyzed. Here, the symbols located at the outermost sides in the conventional lattice constellation are moved symmetrically to fill in empty sides and sunken corners. While the minimum Euclidean distance (MED) among adjacent symbols remains unchanged, the presented cross-lattice constellations have 3~5% reduced average power and upto 25% reduced total volume as compared with the conventional ones. Due to the increase compactness, average power of the new 3-D constellations is lower than that of the conventional ones. As a result, computer simulation verifies that the presented cross-lattice constellations can improve symbol error performance of a digital transmission system about 0.4 [dB]. Hence, the proposed 3-D cross-lattice constellations are appropriate for low-power and high-quality digital communication systems.

PURPOSE. The aim of this review was to analyze the evaluation criteria on mandibular implant overdentures through a systematic review and suggest standardized evaluation criteria. MATERIALS AND METHODS. A systematic literature search was conducted by PubMed search strategy and hand-searching of relevant journals from included studies considering inclusion and exclusion criteria. Randomized clinical trials (RCT) and clinical trial studies comparing attachment systems on mandibular implant overdentures until December, 2011 were selected. Twenty nine studies were finally selected and the data about evaluation methods were collected. RESULTS. Evaluation criteria could be classified into 4 groups (implant survival, peri-implant tissue evaluation, prosthetic evaluation, and patient satisfaction). Among 29 studies, 21 studies presented implant survival rate, while any studies reporting implant failure did not present cumulative implant survival rate. Seventeen studies evaluating peri-implant tissue status presented following items as evaluation criteria; marginal bone level (14), plaque Index (13), probing depth (8), bleeding index (8), attachment gingiva level (8), gingival index (6), amount of keratinized gingiva (1). Eighteen studies evaluating prosthetic maintenance and complication also presented following items as evaluation criteria; loose matrix (17), female detachment (15), denture fracture (15), denture relining (14), abutment fracture (14), abutment screw loosening (11), and occlusal adjustment (9). Atypical questionnaire (9), Visual analog scales (VAS) (4), and Oral Health Impact Profile (OHIP) (1) were used as the format of criteria to evaluate patients satisfaction in 14 studies. CONCLUSION. For evaluation of implant overdenture, it is necessary to include cumulative survival rate for implant evaluation. It is suggested that peri-implant tissue evaluation criteria include marginal bone level, plaque index, bleeding index, probing depth, and attached gingiva level. It is also suggested that prosthetic evaluation criteria include loose matrix, female detachment, denture fracture, denture relining, abutment fracture, abutment screw loosening, and occlusal adjustment. Finally standardized criteria like OHIP-EDENT or VAS are required for patient satisfaction.

Objectives: Diesel engine exhaust (DE) accounts for a significant percentage of air pollutants that are associated with various health outcomes including mortality, asthma, chronic bronchitis, respiratory tract infection, etc. In June, 2012, the International Agency for Research on Cancer (IARC) released the assessment results that classified DE as "carcinogenic to humans" (Group 1). This review is therefore focused on the lung cancer risks of DE. Methods: Literatures were searched using PubMed with key words of "diesel exhaust", "lung cancer", and other related terms for the period between 1990 and 2012. A total of 295 articles were searched and sixteen epidemiologic studies were identified as potentially relevant. Results: Sixteen epidemiologic studies about the lung cancer risks of workers exposed to DE in various occupations were summarized in two tables, 1) retrospective cohort studies and 2) case-control studies. Increased lung cancer risk, although not always smoking adjusted, was observed in 6 out of 8 retrospective cohort studies and 4 of 8 case-control studies. Conclusions: Diesel fuel is widely used in Korea. Exposure to DE is confirmed to be a human carcinogen by IARC. Noncancer health risks of DE also need careful attention as DE is a major source of fine-particle pollution. Along with the efforts for reducing the DE emission through improvements of diesel engines and fuel, and the use of alternative fuels, comprehensive health risk assessment of DE should be conducted to minimize the adverse health effects.

Objectives: The aim of this study is to review the significance of managing "Mibyeong" in geriatric health in Korean medicine and psychology. Methods: We performed a literature search using OASIS, Koreantk, RISS, DBpia, and PubMed databases. We retrieved research articles using the keywords related to mibyeong (未病), sub-health (亞健康), Korean-medicine, psychology and geriatric health. Results: Both Korean medicine and psychology emphasize biological, psychological, and social balance and well-being. In addition, both value individual personality and constitution. Mibyeong is a Korean medical concept suggesting sub-health. Elderly individuals who are in a state of Mibyeong are frail and vulnerable to disorders and illness. Since depression, chronic diseases, low physical and mental activity have fatal outcomes in frail and elderly subjects, positive psychological support and active management of Mibyeong are very important. Conclusions: Geriatric health conditions are associated with chronic disease and multiple risk factors, including physiological, psychological, social, and economic conditions. A preventive and integrative approach is essential for geriatric health as prevention is better than cure for most geriatric diseases and illnesses.

Purpose: This study reviewed articles to identify the optimal rhythmic stabilization or stabilizing reversals application method for improving balance. Methods: The Cochrane, EBSCO, eArticle, Embase, DBpia, KISS, Medline, ProQuest, PubMed, SAGE, ScienceDirect, Scopus, Springer, and Wiley databases were used to search articles from 1990 to January 2017. The search terms included: "rhythmic stabilization" and "stabilizing reversals." Only experimental human studies (randomized controlled trials) that compared the effects of varying the optimal application of rhythmic stabilization or stabilizing reversals to improve balance were included in the review. Non-English language (except Korean) and unpublished studies were excluded. Results: During the research, 1,098 articles were initially identified. Of these articles, nine were randomized controlled trials. Of these nine articles, five were in English, and four were in Korean. In addition, three of the trials did not measure the patients' balance, two did not report the intensity and location of the resistance, and three performed the rhythmic stabilization incorrectly. Only one article met the inclusion and exclusion criteria. The remaining study evaluated the participants' performance of the alternating trunk flexor and extensor isometric contraction of the scapulae using the optimal resistance for 10 seconds in a sitting position. The participants completed three sets of eight repetitions with rest intervals of 30 seconds between the repetitions and 60 seconds between the sets. Conclusion: Due to the lack of the scientific research on the topic, this review may not provide the evidence needed to support the optimal application of rhythmic stabilization or stabilizing reversals to improve balance. Future research should consider the methodological quality to identify the proper rhythmic standardization and stabilizing reversals application method.

Dressing is a seasoned mixture usually used as a stuffing in food. Quality characteristics and antioxidant activity of fruit dressing using lentil legume were investigated. The four groups were divided into D-1(fruit dressing purchased from the local market in Deagu, Korea), D-2 (grapefruit-sugaring dressing prepared with grapefruit sugaring and lentil legume paste), D-3 (vinegar dressing purchased from the local market in Deagu, Korea), D-4 (pineapple-vinegar dressing prepared with pineapple vinegar and lentil legume paste), and then they were analyzed with regard to general compositions, Hunter's color value, mineral and free amino acid content and antioxidant activities. The pH and titratable acidity in all samples ranged from 2.9 to 4.6 and from 0.6 to 1.2%, respectively. The crude protein content were 2.29% for D-2 dressing and 4.03 for D-4 sample, while were not detected D-1 and D-3 samples. In case of Hunter's value, The ' L'and 'a' values of all samples ranged from 45.98 to 56.54 and from -1.59 to 3.30, respectively. The D-4 sample exhibited the higher levels of Ca (215.40 mg/kg), K (1,105.83 mg/kg), Mg (233.63 mg/kg) and Fe (13.78 mg/kg). The levels of heavy metals (As, Pb, Cd and Hg) in all samples were not detected. The contents of total amino acid in D-3 and D-4 samples were 8.269 and 3.419 mg/mL, respectively. The highest contents of total phenols($191.13{\mu}g\;GAE/mL$) and DPPH radical scavenging activity(93.69%, Inhibition) were observed in D-4 sample.

This study searched for the status of medical Systematic Review(SR) publications in Korea and elsewhere for last 10 years, closely analyzing SR research papers by co-authors of Korean librarians. Through interviews with Korean librarians participating in SR, the activities, roles, and difficulties of these librarians were identified, and the results of the interviews helped explore new ways to promote collaboration in SR research. The result of the studied showed that the number of domestic and foreign SR studies has recently increased, and the number of cases where Korean librarians participated in SR research being officially credited as a co-author or acknowledgment source was also grow. The SR librarians in the Korean medical libraries were not only search experts, data collectors, and reference writers, but also did various activities such as designing search strategies, SR search records with complete reproducibility, and DB search tutorship. To promote SR support librarians participated in the interview suggested recruiting new librarians, retraining current librarians, and reformation courses in library and information science. As it is expected that the level of information demand of users and expectations for librarians would also increase in near future, SR librarians' activities and contributions seem to offer a guideline for academic library services that the others should pursue.

Purpose: The aim of this study was to review the literature to determine whether intensive pelvic floor muscle training during pregnancy and after delivery could prevent urinary and fecal incontinence. Methods: Randomized controlled trials (RCT) of low-risk obstetric populations who had done Kegel exercise during pregnancy and after delivery met the inclusion criteria. Articles published between 1966 and 2012 from periodicals indexed in Ovid Medline, Embase, Scopus, KoreaMed, NDSL and other databases were selected, using the following keywords: 'Kegel, pelvic floor exercise'. The Cochrane's Risk of Bias was applied to assess the internal validity of the RCT. Fourteen selected studies were analyzed by meta-analysis using RevMan 5.1. Results: Fourteen RCTs with high methodological quality, involving 6,454 women were included. They indicated that Kegel exercise significantly reduced the development of urinary and fecal incontinence from pregnancy to postpartum. Also, there was low clinical heterogeneity. Conclusion: There is some evidence that for antenatal and postnatal women, Kegel exercise can prevent urinary and fecal incontinence. Therefore, a priority task is to develop standardized Kegel exercise programs for Korean pregnant and postpartum women and make efficient use of these programs.
