본 연구는 흡연시 발생되는 각종 유해오염물질을 효과적으로 저감할 수 있는 친환경 흡연부스를 제작하고, 유해물질의 제거효율 및 효과를 평가하는 것이다. 유입구-HEPA필터-전기집진기(EP)-첨착활성탄-배출구 등의 탈취설비를 갖춘 친환경 자동 흡연부스를 설계 및 제작하여, 흡연연기에 의한 유해오염물질의 제거효율을 측정 및 평가하였다. 측정방법으로는 내부의 배경농도, 설비 가동 시 배출구 농도, 10분 후 흡연부스의 농도를 측정하고, 평가항목으로는 복합악취, 일산화탄소, 미세먼지($PM_1$, $PM_{2.5}$, $PM_{10}$), 총휘발성유기화합물(TVOCs)을 대상으로 하였다. 복합악취 제거효율은 흡연부스 내부에서는 95.37%, 방지설비통과 배출구에서는 97.38%로 우수하였다. 일산화탄소 제거효율은 내부에서는 94.25%, 배출구에서는 98.32%로 나타났다. 또 흡연부스 내부에서의 미세먼지 제거효율은 98.59%이며, 배출구에서는 98.85%로 나타나 미세먼지 제거효율은 매우 우수한 것으로 나타났다. TVOCs는 흡연부스 내부에서는 $26,000{\mu}g/m^3$에서 $5,203{\mu}g/m^3$로 감소하여 79.99%의 제거효율로 나타났고, 환풍기 가동 후 방지설비 배출구에서는 $5,019{\mu}g/m^3$로 측정되어 제거효율은 80.70%로 나타났다. 따라서 본 연구를 통하여 제작, 설계된 흡연부스는 향후 소규모 작업환경 내에서도 각종 유해오염물질들을 제거하는 용도로 적용할 수 있을 것으로 생각된다.

의료분쟁의 해결을 위해 "의료사고 피해구제 및 의료분쟁 조정 등에 관한 법률"이 제정되어 한국의료분쟁조정중재원에서 2012. 4. 8.부터 조정 중재 절차가 시행되었는데, 최근 3개년의 평균 조정절차 개시율은 43%이하로 나타났다. 이에 한국의료분쟁조정중재원은 조정절차 개시율을 높이기 위해 특정 요건에 해당하는 경우 자동개시가 될 수 있는 방안을 고안하였고, 2016. 5. 국회 본회의를 통과하여 같은 달 30.에 공포되었다. 그러나 근본적으로 조정절차 개시율이 오른다고 하더라도, 반드시 현행과 같이 조정성립률이 오를 것이라 단정할 수 없다는 것이다. 오히려 한국의료분쟁조정중재원에서 이와 같은 수치를 높일 계획이라면, 자동개시만이 해법이 아니라 주요 보건의료기관 개설자가 참여하지 않은 근본 이유를 살피고 그에 관한 신뢰를 회복하는 게 주요 과제라할 것이다. 또한 의료인의 안정적인 진료환경을 위해, "의료사고 피해구제 및 의료분쟁 조정 등에 관한 법률" 제51조에서 형법 제268조의 죄 중 업무상과실치사와 단서 조항도 반의사불벌죄가 적용될 수 있도록 개정하여야 한다. 또한 의료기관 개설자나 보건의료인이 대불청구를 할 수 있도록 요건을 신설하는 등 그 외 의료기관의 입장에서, 한국의료분쟁조정 중재원의 조정 절차가 안정적으로 정착할 수 있도록 운영상의 미비에 관하여 제도를 보완할 수 있도록 고언(苦言)한다.

The educational purpose of a junior college is believed to be to effectively train and produce professional workers equipped with the knowledge and skills required in various technical fields of modern society. Since dental technology takes its share of an important role through the enhancement of people's health and the construction of a whlfare society, the prosthodontia department is imposed with a great responsibility to train highly skilled, responsible dental technicians who will meet the social demands. To attain this goal, those who are in charge of the training and education should place emphasis on the development of better educational programs. In other words, the present curriculum which is lacking in many comprehensive aspects, is not satisfactory to provide the students with the required know-how and qualities. As is known, a currculum is the detailed guidance to the efficient operation of an educational program, and that of dental technology is not an exception. In addition, dental technology requires very detailed programs in training, because it requires both diversified and comprehensive application of serveral different fields. The following are the main points to be taken into consideration in developing an effective curriculum for this department. 1. The curriculum should be gradually expanded so that the fundamental subjects will contain principal theories which can be directly applied to the specified majoring subjects. 2. An effective arrangement of time tables should be provided so that basic practice and experiments can be conducted in direct connection with the leatures on the basic theories. 3. For a creative and up-to-date curriculum to help cope with the problems in achieving the aims of technological development and scientific education, intensive and extensive studies should be done on the curricula developed in the advanced countries. 4. The specific majoring subjects should be rearranged to contain new theories which are beneficial to dental technology. As an institution which is spearheaded for ondustrial-educational cooperation, the Junior collegeis role demands that the department should make every possible effect to cultivate highly-skilled technicisns. The following suggestions are made to help work out an ideal curriculum. 1. The basic theory subjects should be selected with consideration toward closely related majoring subjects. 2. The curriculum should be efficiently operated to effectively relate theories with experiments. 3. Subject importance must be rearranged ; It has been found that the ideal proportion of cultural, elective and required subjects is 20%, 20% and 60% respectively. 4. The credit allotments should be reconsidered: The total credits required for completion should preferably be 80; 16 for the cultural and the elective subjects respectively and 48 for the required subject. 5. A Commissioned education system should be formalized for strengthening industrial educational cooperation. 6. Experiments and practice should be intensified with the support of improved laboratory facilities. 7. The training period should be expanded form the present two years to three of four years, in order to produce more highly qualified technicians.

This study was a quasi-experimental study of non-equivalent control group pretest and posttest design. The purpose of this study was to determine the effect of Tai Chi exercise program on physical functions, psychological functions, and fall among the fall-prone elderly. The data were collected from September 19, 2001 to January 31, 2002. The study, conducted at two facilities located in Kwang-ju, was targeted to the ambulatory aged 60 years or older who had at least one of the key fall risk factors. Experimental group participated in Tai Chi exercise for 40 minutes per one time and three times a week for 12weeks at an auditorium. Fifty nine fall-prone elderly were assigned to 12-week Tai Chi exercise program (n=29) and control group (n=30). They underwent tests of lower muscle strength, time for chair stand, balance, flexibility, depression, falls efficacy, fear of falling, and numbers of fall at the baseline and at the 12th week. Numbers of fall and fall injuries were monitored for 16 weeks(12-weeks intervention plus 4-week follow-up periods) using fall calendar. Each participant was given a calendar to record the numbers of fall per day for a month. The calendars were collected at the last week of each month. 1. Tai Chi exercisers showed significant improvement in the strength of knee flexors, and ankle dorsiflexors and plantarflexors compared to the control group. The experimental group had improvement in the strength of knee extensors while the control group did not, with no statistical significance. 2. Tai Chi exercisers reported positive change in the average time of chair stand as compared to the control group. 3. Tai Chi exercisers had significant improvement in flexibility as compared to the control group. 4. There was no significant difference in the depression between the two groups, even though the Tai Chi exercisers maintained depression score in the same level while the others were increased. 5. Tai Chi exercisers showed significant improvements in the falls efficacy as compared to the control group. The falls efficacy was significantly improved among the experimental group while the opposite was identified among the control group. 6. The experimental group reported the significant reduction of the fear of fall, whereas control group reported the opposite. 7. Of the 59 subjects for 16weeks(12weeks intervention period and 4weeks follow up), 9 (31.0%) of the 29 in exercise group and 15 (50%) of the 30 in the control group fell (relative risk=0.62. 95% CI 0.32-1.19), even with no statistical difference. The results suggest that the Tai Chi exercise program can improve the strength of knee flexors, ankle dorsiflexors and plantarflexors, chair stand. flexibility, falls efficacy, and fear of falling for the fall-prone elderly.

Purpose: In this study the present status of the practicum in Fundamentals of Nursing and test for student competency in nursing skills were surveyed. Method: Participants included 72 nursing schools. A structured questionnaire was used for data collection and SPSS 17.0 for data analysis. Results: Credits for Fundamentals of Nursing, credits for practicum and hours per credit were 2.93, 7.34, and 2.14 respectively. Number of students per practice unit, full time assistants and students per assistant were 28.6, 0.6, and 20.2 respectively. Utilization of CPX room and OSCE room for practice was 5.6%, and 9.7% respectively. Of the school, 32.0% included clinical practice in the practicum. 90.3% provided an open lab but only 48.4% had full-time assistants for these clinical practice areas. Testing for nursing skill competency was performed twice a semester in most schools. Utilization of standard patients and high fidelity models for testing was 8.3%, and 23.6% respectively. The test was thought to be inappropriate in 33.4% of the schools. Conclusions: The results suggest that to improve the outcomes, the practicum for Fundamentals of Nursing needs to be changed to include expansion of facilities and human resources, utilization of standard patients and high fidelity models and development of appropriate test methods.

Objectives: The aim of this research is to explore the total heavy metals from a coal-fired power plant burning bituminous coal with wood pellets due to the implementation of the Renewable Portfolio Standard policy (RPS, 10% of electricity from renewable energy resources by 2023). Methods: The research was carried out by collecting archival data and using the USEPA's AP-42 & EMEP/EEA compilation of emission factors for use in calculating emissions. The Monte Carlo method was also applied for carrying out the calculations of measurement uncertainty. Results: In this paper, the results are listed as follows. Sb was measured at 110 kg (2015) and calculated as 165 kg (2019) and 201 kg (2023). Cr was measured at 1,597 kg (2015) and calculated as 1,687 kg (2019) and 1,728 kg (2023). Cu was measured at 2,888 kg (2015) and calculated as 3,133 kg (2019) and 3,264 kg (2023). Pb was measured at 2,580 kg (2015) and calculated as 2,831 kg (2019) and 2,969 kg (2023). Mn was measured at 3,011 kg (2015) and calculated as 15,034 kg (2019) and 23,014 kg (2023). Hg was measured at 510 kg (2015) and calculated as 513 kg (2019) and 537 kg (2023). Ni was measured at 1,720 kg (2015) and calculated as 1,895 kg (2019) and 1,991 kg (2023). Zn was measured at 7,054 kg (2015) and calculated as 9,938 kg (2019) and 11,778 kg (2023). Se was measured at 7,988 kg (2015) and calculated as 7,663 kg (2019) and 7,351 kg (2023). Conclusion: This shows that most heavy metals would increase steadily from 2015 to 2023. However, Se would decrease by 7.9%. This analysis was conducted with EMEP/EEA's emission factors due to the limited emission factors in South Korea. Co-firewood pellets in coal-fired power plants cause the emission of heavy metals. For this reason, emission factors at air pollution control facilities would be presented and the replacement of wood pellets would be needed.

Objectives: Radon may be second only to smoking as a cause of lung cancer. Radon is a colorless, tasteless radioactive gas that is formed via the radioactive decay of radium. Therefore, radon levels can build up based on the amount of radium contained in construction materials such as phospho-gypsum board or when ventilation rates are low. This study provides our findings from evaluation of radon gas at facilities and offices in an industrial complex. Methods: We evaluated the office rooms and processes of 12 manufacturing factories from May 14, 2014 to September 23, 2014. Short-term data were measured by using real-time monitoring detectors(Model 1030, Sun Nuclear Co., USA) indoors in the office buildings. The radon measurements were recorded at 30-minute intervals over approximately 48 hours. The limit of detection of this instrument is $3.7Bq/m^3$. Also, long-term data were measured by using ${\alpha}-track$ radon detectors(${\alpha}-track$, Rn-tech Co., Korea) in the office and factory buildings. Our detectors were exposed for over 90 days, resulting in a minimum detectable concentration of $7.4Bq/m^3$. Detectors were placed 150-220 cm above the floor. Results: Radon concentrations averaged $20.6{\pm}17.0Bq/m^3$($3.7-115.8Bq/m^3$) in the overall area. The monthly mean concentration of radon by building materials were in the order of gypsum>concrete>cement. Radon concentrations were measured using ${\alpha}-track$ in parallel with direct-reading radon detectors and the two metric methods for radon monitoring were compared. A t-test for the two sampling methods showed that there is no difference between the average radon concentrations(p<0.05). Most of the office buildings did not have central air-conditioning, but several rooms had window- or ceiling-mounted units. Employees could also open windows. The first, second and third floors were used mainly for office work. Conclusions: Radon levels measured during this assessment in the office rooms of buildings and processes in factories were well below the ICRP reference level of $1,000Bq/m^3$ for workplaces and also below the lower USEPA residential guideline of $148Bq/m^3$. The range of indoor annual effective dose due to radon exposure for workers working in the office and factory buildings was 0.01 to 1.45 mSv/yr. Construction materials such as phospho-gypsum board, concrete and cement were the main emission sources for workers' exposure.

대한소아감염학회는 2015년 우리나라에서 처음으로 중동호흡기증후군(Middle East Respiratory Syndrome, MERS, 메르스) 환자가 발생하여 보건의료 응급 상황 발생의 긴박했던 시기에 이에 대한 대처에 참여하였다. 우리 학회는 메르스 발생 시 학회 홈페이지에 관련 공고문을 즉시 게시하였고 소아청소년에서의 메르스 환자의 발생시 의심 환자의 검사와 진단 및 국민안심병원 운영을 위해 소아청소년 MERS (중동호흡기) 검사 지침, 국민안심병원 소아청소년과 운영지침을 발빠르게 배포하였다. 이는 메르스 의심환자에 대한 접근에서 소아청소년에서 흔한 호흡기 질환 환자들이 메르스로 오인되어 불필요한 공포, 검사 및 격리를 당하지 않도록 하기 위함이었다. 이를 통해 소아청소년 환자를 진료하는 의사들과 이들의 보호자들을 안심시켰고 결국 많은 심리적 공포와 의료 비용을 감소시켰으며 메르스 종식 시 돌이켜보니 이는 결국 적절한 조치와 가이드라인이었음이 증명되었다. 앞으로 대한소아감염학회와 회원이 유관기관과 긴밀한 협조와 소통을 할 수 있는 체계 시스템을 구축해야 하며 상급의료기관의 소아청소년 감염전문의 필수 상주 및 이에 의한 감염관리료 제도 장착과 수가 신설 및 개선을 유도하는 등의 추진이 필요하다.
