Objectives This study is designed to evaluate the safety of Bojungikgi-tang soft extract in healthy male volunteers. Methods 12 healthy male volunteers were recruited and this study was carried out by a single center. Laboratory test results, vital signs of the volunteers were collected to evaluate safety. According to registration order, the 12 subjects were allocated by serial number. To evaluate safety, blood samples were taken and vital signs were checked 4 times - screening, pre administration, post administration and follow up-during the whole trial. The difference between pre (before medication [0 hr]) and post-administration (after medication [48 hr]) variables was summarized as mean±standard deviation. The normality test was performed using the Kolmogorov-Smirnov test and Shapiro-Wilk test. When the normality is satisfied, the paired t-test is applied. Otherwise, the non-parametric method, Wilcoxon signed rank test is applied. The significance level was p<0.05. The incidence of all adverse effects are shown in percentage. Results In the case of red blood cell, hemoglobin, hematocrit, lymphocytes, neutrophils, protein, γ-glutamyl transpeptidase values, the normality test result of the variable for the difference value before and after the dosing has a significance level <0.05. But most of values did not deviate from the normal range, and the deviation from the normal range could not be regarded as the significance associated with this clinical trial. And adverse event wasn't observed associated with the clinical trial drug. Conclusions Bojungikgi-tang soft extract were considered to be safe for healthy male volunteers.

큰 규모의 산업용 보일러는 고온, 고압을 이용하는 설비이며, 보유수량이 많아 폭발시 엄청난 에너지가 방출된다. 현재 산업용 보일러는 대부분이 LNG, LPG 등의 가스연료를 사용하고 있고, 연료가 설비와 같은 공간에 존재하기 때문에 보일러 사고 발생시 화재, 폭발 등 2차 피해 가능성이 높다. 뿐만 아니라 단위 사고당 2.51명의 사상자를 발생시키는 대단히 위험한 설비로 운영에 특별한 주의와 관리가 필요하다. 일정 규모 이상의 보일러는 에너지이용 합리화법, KS, 산업통상자원부 고시 등에 따라 한국에너지공단에서 검사를 실시하고 있다. 본 연구에서는 검사 결과 불합격 사항을 바탕으로 위험인자를 구성하고, 검사원, 기기 관리자, 유지보수 담당자, 제조업체 담당자에게 설문을 실시하여 보일러 안전관리에 중요하게 판단하는 기준을 AHP(계층분석방법)을 통해 분석하였다. 분석결과 공통적으로 인식하고 있는 위험인자는 관리소홀, 계측기 고장, 규격미달, 누수, 누설로 분석되었고, 접속, 용접, 스케일, 부식 등은 상대적 중요성이 낮은 것으로 분석되었다. 모든 집단과 경력에서 중요성이 높다고 인식하고 있는 위험인자는 이미 관리가 잘 되고 있다고 판단되나, 중요성이 낮게 분석된 위험인자는 관리누수가 발생되지 않도록하여 보일러를 안전하게 사용할 수 있도록 해야 한다.

Background: High-alert medications (HAMs) are medications that bear a heightened risk of causing significant patient harm if used in error. To facilitate safe use of HAMs, identifying specific HAM lists for clinical setting is necessary. We aimed to develop the national level HAM list for acute care setting. Methods: We used three-step process. First, we compiled the pre-existing lists referring HAMs. Second, we analyzed medication related incidents reported from national patient safety incident report data and adverse events indicating medication errors from the Korea Adverse Event Reporting System (KAERS). We also surveyed the assistant staffs to support patient safety tasks and pharmacist in charge of medication safety in acute care hospital. From findings from analysis and survey results we created additional candidate list of HAMs. Third, we derived the final list for HAMs in acute care settings through expert panel surveys. Results: From pre-existing HAM list, preliminary list consisting of 42 medication class/ingredients was derived. Eight assistant staff to support patient safety tasks and 39 pharmacists in charge of medication safety responded to the survey. Additional 44 medication were listed from national patient safety incident report data, KAERS data and common medications involved in prescribing errors and dispensing errors from survey data. A list of mandatory and optional HAMs consisting of 10 and 6 medication classes, respectively, was developed by consensus of the expert group. Conclusion: We developed national level HAM list for Korean acute care setting from pre-existing lists, analyzing medication error data, survey and expert panel consensus.

Objective : The objective of this study is to determine the effects of fear of Middle East respiratory syndrome (MERS) on socio-psychological health during an outbreak of MERS and the post-traumatic stress as a mediator on the relationship between stress and socio-psychological health. Methods : Visual Analog Scale, Impact of Event Scale -Revised, Psychosocial well-being index short form was implemented for 150 medical persons who worked at the hospital in which exposure to MERS cases had been confirmed and 96 ordinary people. A Pearson correlation coefficient and a hierarchical multiple regression was carried out to confirm the effect of fear of MERS and the mediating effect of post-traumatic stress between fear and socio-psychological health. Results : The higher the fear, the lower the socio-psychological health in both healthcare workers and the public (r=0.32, p<0.01) and the higher post-traumatic stress (r=0.32, p<0.01). But, the research results showed that only healthcare workers had a partially mediating effect of post-traumatic stress in the relationship between fear and socio-psychological health (${\beta}=0.45$, t=6.33 p<0.001), (${\beta}$ value : 0.39>0.26). Conclusion : This study demonstrated that the post-traumatic stress can indirectly lead to a negative effect on the socio-psychological health of healthcare workers when under the fear of MERS and shows adverse effects on psycho-social wellbeing. This suggests that clinical intervention and psycho-social approach aiming at reducing post-traumatic stress is important to maintain mental health during crisis development.

Objectives : This study aimed to assess the effectiveness and safety of Taegeuk acupuncture for patients with chronic musculoskeletal pain. Methods : A retrospective analysis of the electronic medical records of Pusan National University Korean Medicine Hospital from March 2012 to March 2013 was performed. Eligible cases were outpatients who had received at least six sessions of Taegeuk acupuncture for their pain and had agreed to the use of their medical records for research purposes. Pain levels, heart rate variability, and patients' perceptions of the safety of acupuncture were investigated through the medical records and follow-up telephone interviews. Results : Fifteen cases were selected for analysis. All had suffered from musculoskeletal pain for at least one year. After six sessions of Taegeuk acupuncture, the average score on the pain numeric rating scale decreased from $6.7{\pm}2.0$ to $2.9{\pm}2.2$(a 43 % reduction). Follow-up telephone interviews revealed that patients experienced no adverse event after Taegeuk acupuncture. Conclusions : Patients with chronic musculoskeletal pain showed a reduction of more than half of the baseline pain after six sessions of Taegeuk acupuncture. However, the beneficial effects observed in this retrospective analysis should be interpreted with caution due to selection and recall bias. Further randomized controlled trials of Taegeuk acupuncture for chronic musculoskeletal pain are warranted.

Extensive forest fires occurred across the border in Russia. particularly east of Lake Baikal between the Amur and Lena rivers in May 2003. These forest fires released large amounts of particulates and gases into the atmosphere. resulting in adverse effects on regional air quality and the global radiation budget. Smoke pollution from the Russian fires near Lake Baikal was sometimes transported to Korea through Mongolia and eastern China. In this study ground based radiation (visible and UV-B) data measured during May 2003 at Seoul and Kwangju were analyzed to estimate smoke aerosol impacts on solar radiation. Surface criteria air pollutants ($PM_{10}$, CO, $O_3$) data were also obtained from National Institute of Environmental Research (NIER) during smoke aerosol event period (19 May~24 May 2003). Large Aerosol Optical Depth (AOD) 1.0~3.0 was observed during this period due to the influence of the long range transport of smoke aerosol plume from the Russian fires, resulting in short-wavelength direct aerosol radiative forcing of -90~ -200W/$m^2$. These smoke aerosol plume caused decrease in surface UV-B radiation up to 80% and increase in PM_(10) concentration up to 200${\mu}g/m^3$ exceeding the 24 hour ambient air quality standard.

The World Health Organization (WHO) announced the emergence of a novel influenza on April 24, 2009, and they declared pandemic on June 11. In Korea, the proportion of influenza-like illness and the consumption of antiviral agents peaked in early November. The government established the Central Headquarters for Influenza Control and operated the emergency response system. In the quarantine stations, we checked the body temperature and collected quarantine questionnaires from all the arrivals from infected countries. We also isolated the confirmed cases in the national isolation hospitals. However, as the community outbreaks were reported, we changed strategy from containment to mitigation. We changed the antiviral agent prescription guideline so that doctors could prescribe antiviral agents to all patients with acute febrile respiratory illness, without a laboratory diagnosis. Also the 470 designated hospitals were activated to enhance the efficacy of treatment. We vaccinated about 12 million people and manage the adverse event following the immunization management system. In 2010, we will establish additional national isolation wards and support hospitals to establish fever clinics and isolation intensive care unit (ICU) beds. We will also make a computer program for managing the national isolation hospitals and designated hospitals. We will establish isolation rooms and expand the laboratory in quarantine stations and we will construct a bio-safety level 3 laboratory in each province. In addition, we plan to construct a bio-safety level 4 laboratory at a new Korea Centers for Disease Control and Prevention (KCDC) facilities in Ossong.

Objectives : To report the cases of forgotten needles found in the patients' bodies since Dong-guk University Ilsan Hospital opened, and arouse considerable attention to prevent recurrence. Methods : Oriental medical doctors in the hospital has applied acupuncture on patients' bodies in case of need, and the other staffs removed the needles after treatment. Results : All the patients in the cases had cerebrovascular disease with paralysis, aphasia, cognitive disorder and disturbance of consciousness as well as dysphagia requiring gastrotomy tube and dysfunction of respiration requiring tracheal cannula. The pathways the acupuncture needles were passing through are presumed to be transtracheal via the hole of tracheal cannula in two cases, and transgastrointestinal via mouth or the opening of gastrotomy tube. The needle was excreted with stool without any harm to the patient in the latter case, while the impact of the needles on the respiratory system or thorax of the patients in the former two cases is ambiguous. The hospital has taken some measures to prevent recurrence. Conclusions : There are not a few at high-risk of occurrence of forgotten needles that might induce medical problems among patients in oriental medical clinics or hospitals. Authors expect this report arouses all the people involved in the whole procedure of acupuncture treatment, including oriental medical doctors, nurses, nurse-assistants and caregivers considerable attentions to the possible occurrence and risk of forgotten needles.
