  • Objectives : The aim of this systemic review was to summarize and compare adverse effect of spinal manipulation at domestic and abroad. Methods : We searched articles in Korean databases and Pubmed. We selected and analysed the articles met inclusion criteria. Results : 51 cases were included. 32 cases in Pubmed show that adverse effect related to cervical rotation and high velocity low amplitude(HVLA) thrust manipulation. It leads to severe adverse effect and sequela about vascular. While, 19 cases in Korean articles shows that domestic spinal manipulation is more safe becase of lower use of high velocity low amplitude(HVLA) thrust. It leads to low incidence of vascular adverse effect and no sequela. Conclusions : We concluded that Chuna is difficult manipulation because of possibility of adverse effect. Chuna is recommended to be taken by licensed medical practitioners who are skilled and complete the regular curriculum. Further studies like meta analysis about spinal manipulation are needed to estimate incidence of adverse effect. And adverse effects are going to be collected continually through randomized controlled trials(RCT) related to spinal manipulation.

  • The objective of this study is to assess the effect of interpregnancy interval on fetal outcome among women with term premature rupture of membrane in public hospitals, Ethiopia, 2017. Facility based follow up study was conducted in Southern Ethiopia public hospitals from February 30, 2017 to August 20, 2017. Among 150 observed mothers with interpregnancy interval of less two years, 46.67 % (95% CI: (7.170, 29.93) of them experienced adverse birth outcome, but among 173 women with interpregnancy interval of two and above years, 5.78% (95% CI: (7.170, 29.93) of them experienced adverse birth outcome. The odds of adverse birth outcome were more among women with interpregnancy interval of less than two years (AOR=17.899, 95%CI: [6.425, 49.859]. The effect of interbirth interval of less than two years on adverse birth outcome of newborn was increased by length labor of >=24 hours, induction of labour and cesarean section delivery. Interpregnancy interval of less than two years, in collaboration with other risk factors, is the main predictor of adverse birth outcome. Therefore especial attention should be given to mothers with birth spacing by using family planning methods to reduce adverse birth outcome.

  • Ginseng is a perennial herb widely used in China, Japan, and Korea. It is also one of the most commonly used herbal medicines in the U.S. Although it is generally considered safe to use, adverse effects associated with ginseng use have been reported. Inappropriate ginseng use, such as high dose administration, may cause insomnia, headaches, diarrhea, as well as cardiovascular and endocrine disorders. Other factors that may contribute to adverse effects of ginseng include the variety of ginseng species, variability in commercial ginseng preparations, and potential ginseng-drug interactions. To minimize adverse effects of ginseng, consumers should be advised to use it appropriately, and the herbal industry should try to provide standardized ginseng preparations.

  • Ecotoxicology is a research area for adverse effect of chemicals to ecosystem. While toxicology is directly related to human health, relation between ecotoxicology and human health is indirect. In this connection, public awareness of environmental effect has been rather behind that for health effects. Historically the first concern in ecotoxicology was adverse effect of pollution on organisms in waters receiving industrial wastewater. (omitted)

  • Objectives : The aim of this review is to investigate studies on skin adverse reactions and to demonstrate subjects related to the adverse effects in dermatology. Methods : Electric searches were performed with KISS(Korean studies Information Search System) and the key words were combination of 'skin' and 'adverse effect'. 87 literatures investigated in this review were issued from 1900 to 2016. Results : Among the 87 papers, dermatologic adverse reactions were reported in 83 papers in medicine, accounting for 95.4%. Of the adverse effects seen on the skin, 84 discoloration such as erythema, pigmentation and hemotelangiosis were the most common, accounting for 21%. Among the medical adverse reactions not seen on the skin, 21 infection were the most common, accounting for 25%. Among the subjective adverse reactions, of which 32 pruritus were the most common, accounting for 43%. Among the 87 papers, there were 3 cases with underlying diabetes and 3 cases with underlying hypertension, followed by 2 cases with chronic renal failure, HBV, atopic dermatitis and respectively 1 case with alcoholism, depression addiction, multiple myeloma, arthritis and psoriasis. The most frequent period until adverse reactions appeared was within 2 weeks, accounting for 13 papers. And 4 were the most frequent adverse reactions lasting less than 1 month, and 4 were more than 3 months and less than 6 months. There were 48 cases where adverse reactions were caused by nonmedical practioner's treatment. The adverse reactions by the pharmacist were the highest at 11 cases (23%). There were 17 cases of adverse reactions due to medical treatment, among which dermatologists and nondermatologists accounted for the majority of 5 cases, 29%. The most common cause of adverse reactions was the application of external medicine (41 cases), followed by 36 cases of foreign body implantation, eyebrow tattooing, ear piercing, etc. Conclusions : In this report, we demonstrated patterns of adverse reactions in the medical field of dermatology caused by non-medical personnel than medical personnel. We suggest that more effort should be followed by medical personnel to establish clear awareness of skin disease and by patients to be aware of the risks of the illegal medical treatment by non-medical personnel.

  • Unlike conventional airplane, a WIG craft experiences righting moment and adverse yaw moment in banked turning in ground effect. Numerical simulations are carried out to study the aerodynamics of banked wing in ground effect. Configurations of rectangular wing and delta wing are considered, and performance of endplates and ailerons during banking are also studied. The study shows that righting moment increase nonlinearly with heeling angle, and endplates enhance the righting. The asymmetric aerodynamic distribution along span of wing with heeling angle introduces adverse yaw moment. Heeling in ground effect with small ground clearance increases the vertical aerodynamic force and makes WIG craft climb. Deflections of ailerons introduce lift decrease and a light pitching motion. Delta wing shows advantage in banked turning for smaller righting moment and adverse yaw moment during banking.

  • It is known that previous models are unsatisfactory in predicting adverse pressure gradient turbulent flows. In the present paper, a revised low Reynolds number $k-{\varepsilon}$ model is proposed. In this model, a newly developed term is added lo the dissipation rate equation. In order to reflect appropriate effects for an adverse pressure gradient. The added tenn is derived by considering the distribution of mean velocity and turbulent properties in the turbulent flow with, adverse pressure gradient. The new $k-{\varepsilon}$ model was applied to calculations of flat plate flow with adverse pressure gradient, conical diffuser flow and backward facing step flow. It was found that the three numerical results showed better agreement than other models compared with DNS results and experimental ones.

  • Background: This study investigates the relationship of socioeconomic status with adverse birth outcomes (low birth weight, preterm birth) and the relationship of socioeconomic status with infant mortality, using the birth cohort in Korea, 1995-2010. Methods: 8,648,035 births from National Statistics Offics, 1995-2010 were studied with respect to social variation in adverse birth outcomes and infant mortality in Korea. The effect of social inequality was examined against adverse birth outcomes and infant mortality using multivariate logistic regression after controlling for other covariates. Results: Social inequality were observed in adverse birth outcomes: low birth weight (LBW, 1,500-2,499 g), very LBW (1,000-1,499 g), and extremely LBW (500-999 g) as well as moderately preterm birth (PTB, 33-36 weeks), very PTB (28-32 weeks), extremely PTB (22-27 weeks), and infant mortality. The effect of social inequality was higher among moderately LBW (1,500-2,499 g) and PTB (33-36 weeks) than very or extremely LBW and PTB. Conclusion: The social inequality in adverse birth outcomes (low birth weight and preterm) and infant mortality existed and increased in Korea from 1995 to 2010. The effect of maternal education on adverse birth outcomes as well as infant mortality was apparent in the study results. Especially, social inequailiy in infant mortality was greater among the sub-normal births (low birth weight [1,500-2,499 g] or preterm birth [33-36 weeks]), which suggests, social interventions should aim at more among the subnormal births. This study suggest that tackling inequality in births as well as infant mortality should be focused on the social inequality itself.

  • Objective : To investigate documented surveys about adverse events of acupuncture therapy. Methods: We searched Medline with the terms of 'acupuncture/adverse event(s)', 'acupuncture/side effect(s)' and 'CAM/adverse event(s)' using Pubmed and set the limits to human study. Results: There were 5 prospective studies, 3 reviews and 3 surveys in our searching. There were 3 reports about acupuncture related adverse events in UK ranging from 10.7% to 15% of which the rate of significant events were from 0.13% to 0.14%. In Germany, there were 11% of acupuncture related adverse events in one report and 7.5%(significant events were 45 in 190,924 patients) in another report. In Australia, one study reported that every adverse event associated with acupuncture occurred in 8-9 month per one practitioner. In Japan, 0.14% of acupuncture related adverse events in 48 practitioners were reported in one systemic review. A cumulative review about significant adverse events associated with acupuncture reported 715 adverse events of which most frequent accidents were pneumothorax and central nervous system injury. Conclusion : The risk of adverse event associated with acupuncture is far lower than that associated with other general medical interventions. However, some safety guidelines about the acupuncture performance are needed.
