In this study, we analyzed how the revenue water ratio(RWR) is affected by changes in conditions of the water supply area, such as the ratio of aging pipes, maintenance conditions, and revenue water. As a result of analyzing the impact of pipe aging and maintenance conditions on the RWR, it was confirmed that the RWR could be decreased if the pipe replacement project to improve the aging pipe ratio was not carried out and proper maintenance costs were not secured. It was also confirmed that an increase in the revenue water could be operated to facilitate the achievement of the project’s target RWR. In contrast, a decrease in the revenue water due to a population reduction could affect the failure of the target RWR. In addition to analyzing the causes of variation in the RWR, the calculation of estimated project costs was considered by using leakage reduction instead of RWR from recent RWR improvement project cost data. From this analysis, it was reviewed whether the project costs planned to achieve the target RWR of the RWR improvement project in A city were appropriate. In conclusion, the RWR could be affected by variations in the ratio of aging pipes, maintenance conditions, and revenue water, and it was reasonable to consider not only the construction input but also the input related to RWR improvement, such as leakage reduction, when calculating the project cost.

The goal of this study was to measure the indoor and outdoor fine and ultrafine particulate matter concentrations (PM10, PM1.0) of some houses in Yeosu and in S university in Asan from March to September 2018. PM10 concentration in indoor air in Yeosu area was 18.25 μg/m3, while for outdoor air it was 14.53 μg/m3. PM1.0 concentration in indoor air in the Asan area was 1.70 μg/m3, while for outdoor air it was 1.76 μg/m3, showing a similar trend. Heavy metal concentrations in the Yeosu region were the highest, at Mn 2.81 μg/m3, Cr 1.30 μg/ m3, and Ni 1.11 μg/m3 indoors. Outside, similar concentrations were found, at Cr 3.44 μg/m3, Mn, 2.60 μg/m3, and Ni 1.71 μg/m3. Our analysis of indoor and outdoor PM concentrations in the Asan region, which was carried out using the MOUDI (Micro-orifice Uniform Deposit Impactor) technique, found that PM concentration is related to each particle size concentration, as the concentration of 18 μm and 18-10 μm inside tends to increase by 3.2- 1.8 μm and 0.56-0.32 μm.

In this study, 102 residents in Gwangyang and Yeosu were evaluated for exposure to levels of urethral arsenic from April 2017 to June 2018. The geometric mean concentration of the urinary arsenic in the total studied was 154.30 μg/L, with the figure for the Gwangyang area being 201.18 μg/L and the figure for the Yeosu area being 200.21 μg/L, which signifies that there was no real difference between the two regions. The figures for males and females were 173.81 μg/L and 136.98 μg/L, respectively, indicating higher levels for males. In the case of males, the risk assessment of arsenic (As) showed that 0.54 does not exceed 1 and approximately 11.3% exceeded the reference value. For women, the number of hazardous materials did not exceed 1.41 and approximately 5.1% exceeded the reference value of the total arsenic exposure survey.

In this study, 40 residents of the Gwangyang and Yeosu areas were assessed for their level of exposure to heavy metals (As, Cd, Ni) from April 2017 to June 2018. The aim was to understand the differences in levels of indoor exposure to heavy metals (As, Cd, Ni), and a health risk assessment was conducted to determine whether there was any fatal cause from carcinogenic elements. The mean concentrations of PM10 particles indoors were As 0.24 μg/m3, Cd 0.07 μg/m3, and Ni 0.89 μg/m3. The health risk assessment for the arsenic, cadmium, and nickel in indoor air confirmed that the mean values exceeded the cancer risk tolerances specified by the U.S. EPA, for As (males 3.07 × 10−4, females 3.35 × 10−4), Cd (males 3.83 × 10−5, females 4.18 × 10−5), and Ni (males 6.36 × 10−5, females 6.95 × 10−5).

In this study, we measured the concentration of Particulate Matter(PM10), Formaldehyde(HCHO), and Total Bacteria Count (TBC) at two facilities: day care centers, and postnatal care centers located in the cities of Gyeonggi, Gangwon, Jeolla and Gyeongsang from January 1, 2012 to December 31, 2015. PM10 concentration was similar to the day care centers and postnatal care centers. HCHO concentration was the highest in the postnatal care centers. TBC concentration was the highest in the day care centers. Comparing the different cities, PM10 concentration was the highest in Gyeonggi, HCHO concentration was the highest in Gyeonggi, and TBC concentration was the highest in Gyeonggi. As a result of HCHO's risk assessment, it was found that adults exceeded the carcinogenicity tolerance of 10−6 specified by the US EPA. This study is expected to be helpful in preventing damage to health from the contaminated indoor air at sensitive facilities, and can be used as basic data for indoor air quality management.

In this study, we measured the concentration of Particulate Matter (PM10), Formaldehyde (HCHO), and Total Bacteria Count (TBC) at three facilities: elderly care centers, day care centers, and postnatal care centers located in the cities of Seoul, Sejong, Daegu and Ulsan from January 1, 2012 to December 31, 2015. PM10 concentration was the highest in the day care centers and HCHO concentration was the highest in the postnatal care centers. TBC concentration was the highest in the day care centers. Comparing the different cities, PM10 concentration was the highest in Sejong, HCHO concentration was the highest in Seoul, and TBC concentration was the highest in Daegu. This study is expected to be helpful in preventing damage to health from the contaminated indoor air at sensitive facilities, and can be used as basic data for indoor air quality management.

The purpose of this study is to illustrate the design of safety suits based on energy-harvesting technology, particularly targeting street cleaners who must work at night with high mobility. The design focuses on applying lightweight energyharvesting tools and illuminant into the wear. The design development reflects feedback from testers collected via survey constituting a key methodology. The development process has two main stages. Each stage uses a process of design prototyping, internal examination, test sampling, test wearing, and wearers’ feedback via survey that consists of questions on visibility, wearing convenience, and washability. The first stage results show the design of safety suits with energy-harvested LED illuminant inserted and the survey results collected from street cleaners dressed in 4 sample and 80 actual suits in total. Improved based on the first-stage survey results, the second stage designs the suits with detachable energy-harvested EL tape. From these 5 sample and 30 actual second-stage suits, the additional survey indicates that this second-stage design facilitates more visibility and convenience in washing and wearing than the first-stage design. Accordingly, one can expect that this new design can apply not only to safety suits for night workers but also to handicapped or outdoor sportswear applications in the future.

This study was conducted targeting 30 residents of Gwangyang industrial complex area from April to May 2017 to assess their level of exposure to VOCs and conduct a health risk assessment for individual exposure. The aim was to understand the difference in levels of indoor, outdoor and personal exposure to VOCs (benzene, toluene, ethylbenzene, m-xylene, p-xylene, o-xylene) and a health risk assessment was conducted to determine whether there was any fatal cause from carcinogenic or non-carcinogenic elements from a respiratory disease patients. In the case of benzene in the air, the geometric levels of the group are indoor, outdoor and personal exposure; on the CTE, RME condition and Monte-Carlo analysis, all subjects were seen to exceed the carcinogenicity tolerance of 10−6 specified by the US EPA. In the case of toluene, ethylbenzene, m-xylene, p-xylene, o-xylene on the CTE, RME condition and Monte-Carlo analysis, the non-carcinogenic standard of 1 was not exceeded.

This study was carried out to investigate the presence of a correlation between heavy metals in urine samples and upper airway diseases. For the study, 51 household residents of Gwangyang, both with and without upper airway disease, were targeted. Urine samples were collected from the subjects along with a questionnaire from April 24th to 27th, 2017. The heavy metals in the urine samples were preprocessed and analyzed using an inductively coupled plasma/mass spectrometer. The geometric mean concentration of urinary arsenic and cadmium was 138.66 μg/L and 0.75 μg/g creatinine among those with upper airway disease and 166.42 μg/L and 1.19 μg/ g creatinine among those without upper airway disease. This was not a statistically significant difference. The concentration of urinary arsenic and cadmium was found to be increased by 1.19 times (95% CI; 0.15-9.31) and 1.26 times (95% CI; 0.31-5.04) in household residents with upper airway diseases with more than 144.86 μg/L and 0.85 μg/g creatinine, respectively.

The purpose of this study was to evaluate the concentration of airborne particulate matter and heavy metals in the houses of the respiratory tract disease patients and a control group of residents in the city of Gwangyang. The particulate matter was measured using a mini-volume air sampler and then weighed three times using a micro balance to calculate the weighted average value. The heavy metals in the particulate matter were extracted using a hot plate and analyzed using an inductively coupled plasma/mass spectrometer. The average concentration of particulate matter in the outdoor air (34.478 μm/m3) was higher than that in the indoor air (16.794 μm/m3), showing a statistically significant difference (p<0.001). The average concentration of copper, manganese and chromium in the indoor and outdoor air were higher in the houses of those in the study group than those of the control group. In addition, there was a generally high correlation between particulate matter in the outdoor air and heavy metals in the indoor and outdoor air concentration (p<0.05).

The objectives of this study were to investigate the effects of PM10 and O3 concentration on the symptoms of allergic diseases. The questionnaire was used to determine whether or not symptoms of allergic diseases were present from September to October 2012. The air pollution concentration data used was the corresponding point CEM (continuous emission monitoring) data. The average concentration of PM10 was 56.09 μg/m3 in the control area, and the concentration in the exposed area was 40.44 μg/m3. In the two areas, concentration of O3 was 28.73 ppb and 28.74 ppb, respectively. The total average concentrations of PM10 and O3 were 45.66 μg/m3 and 28.73 ppb in the Gwangyang area. The rate of asthma diagnosis was higher in the control area (9.6%) than in the exposed area (4.1%), but the rate of allergy eye disease was higher in the exposed area (23.9%) than in the control area (16.5%). There was a significant difference in the symptoms of some allergic diseases when the relative concentration of PM10 and O3 were high and low.

In this study, the distribution of each facility group, the pollution level of local municipalities and the status of self-measurement were investigated and analyzed using data provided by the Ministry of Environment. It was found that most of the workplaces to be managed are facilities of sensitive class, indoor parking lots and largescale stores. The results of the survey on the total pollution level by facility group showed that the rate of contamination was the highest in the facilities where there are many sensitive users, including the subway station and the underground shopping malls. Through self-measurement, in the case of fine particle matter, it was found that it was present in amounts of 51.71 μg/m3, 50.72 μg/m3, 44.47 μg/m3 and 54.44 μg/m3 in medical institutions, day care centers, elderly care facilities and postnatal care centers, respectively. Also, there were facilities exceeding the standard in the medical institutions. However, most of the pollutants in the facilities surveyed by the municipality are higher than the self-measured concentrations, so it is necessary to examine the cause of such pollution.

In this study, we analyzed the concentration of cadmium and mercury in urine and lead in blood from 668 residents in the exposed and compared areas in Gwangyang-si and Yeosu-si, from July 2013 to December 2015. According to the lifestyle (past smoking, current smoking, passive smoking, drinking and exercise), the concentration of cadmium in urine was higher in the compared areas than in the exposed areas in Gwangyang. However, the concentration of cadmium in urine according to the lifestyle except drinking was higher in the exposed areas than in the compared areas in Yeosu. According to the past smoking and current smoking, the concentration of mercury in urine was higher in the compared areas than in the exposed areas in Gwangyang, but the passive smoking, drinking and exercise showed similar concentration levels both in the exposed and compared areas in Gwangyang. The concentration of mercury in urine according to the past smoking and current smoking was higher in the exposed areas than in the compared areas in Yeosu, but the concentration of mercury in urine according to the drinking and exercise was lower in the exposed areas than in the compared areas in Yeosu. According to the past smoking, the concentration of lead in blood showed similar concentration levels in the exposed and compared areas in Gwangyang, but regarding current and passive smoking, it was higher in the compared areas than in the exposed areas in Gwangyang. Especially, the concentration of lead in blood according to the drinking in Gwangyang showed statistically significant difference (p<0.05). The concentration of lead in blood according to the lifestyle was higher in the compared areas than in the exposed areas in Yeosu.

본 연구는 무용전공 고등학생들의 완벽주의와 무용 내적동기의 관계에서 스트레스 대처의 매 개효과를 검증하는 데 목적을 두었다. 이에 따라, 예술고등학교에서 무용을 전공하는 197명 학 생들의 완벽주의, 스트레스 대처, 내적동기를 설문조사를 통하여 측정하였다. 자료의 분석은 기 술통계와 상관분석과 함께 스트레스 대처의 매개효과 검증을 위해 위계적 회귀분석을 실시하였 으며, 매개효과의 통계적 유의성을 검증하기 위해 Sobel test를 실시하였다. 위계적 회귀분석 결 과, 대처의 하위요인 중 문제중심, 정서중심, 회피 대처가 완벽추구성향(striving for perfection)과 내적동기의 관계를 통계적으로 유의하게 부분 매개하는 것으로 나타났다. 불완벽에 대한 부정적 반응(negative reactions to imperfection)과 내적동기의 관계에서는 문제중심적 대처와 회피 대처의 유의한 매개효과가 확인되었다. 이러한 결과에 따라 본 연구는 완벽주의 성향을 가진 무용전공 고등학생들이 문제중심적인 대처를 사용할 때 무용에 대한 내적동기를 더욱 증진시킬 수 있다 는 사실을 논의하고, 미래연구방향을 제시하였다.

본 연구는 무용영재 판별 시, 보다 신뢰가 높고 타당하게 평가할 수 있는 평가방법은 무엇인 지 선행연구와 문헌을 통해 모색하는데 그 목적이 있다. 무용은 신체를 통해 표현하는 예술로서, 무용영재성을 판별하기 위해서는 신체골격이 완성되기 이전에 조기선발 되어야 한다. 하지만 조 기선발은 선발시기의 특성상, 무용영재로서의 잠재된 능력을 100% 판별해내기에는 다소 무리가 있으므로 무용영재성 판별은 매우 신중하게 고려되어야 한다. 일반 영재성 평가방법을 살펴보면, 학생의 영재성을 평가하는 교사평가방법과 자녀의 영재성 을 관찰하는 부모관찰방법, 그리고 자신을 평가하는 자기진단평가방법 등 다양하게 적용하고 있 다. 다양한 평가방법을 동원하여 영재성을 판별하는 이유는 단일한 평가방법에서 나타나지 않았 던 잠재된 영재성을 판별해 내고, 판별결과에 대한 오류를 최소화하기 위해서이다. 이에 따라 일 반 영재성 평가도구는 평가자의 특성을 고려하여 다양하게 개발되고 있으며, 예술분야에서도 예 술영재성 평가도구 개발에 관심을 기울이고 있다. 특히 무용영재성 판별에 관한 선행연구 중에서 도 무용영재성을 객관적으로 평가할 수 있는 측정도구를 개발(이진효, 2010)하여, 보다 신뢰가 높 고 타당하게 무용영재를 선발할 수 있는 기틀을 마련하였다. 하지만 앞서 언급하였듯이, 무용영 재는 조기선발이라는 선발시기를 고려해볼 때, 잠재되어 있는 능력을 다차원적으로 평가하기 위 해서는 선행연구에서 개발된 교사평가도구만으로는 부족하다. 따라서 본 연구는 일반영재성 판별 방법을 통해 무용영재성 판별의 타당성을 높이는 평가 방법을 모색하고, 국내·외 영재기관에서 는 어떤 평가도구를 통해 무용영재를 선발하는지 분석하였다. 본 연구를 통해 분석된 무용영재성 판별 방법은 추후 무용영재성 평가도구를 개발하고자 할 때, 유용한 자료로서 제공될 뿐만 아니라 무용영재로서 선발된 이후, 후천적인 노력을 통해 발현 되는 무용영재성 요인에 대해서도 보다 객관적으로 평가할 수 있는 평가기준을 제공할 것이다.

국내의 다문화 가정이 급증하고 다문화 사회가 도래하는 급격한 변화를 겪게 됨에 따라, 교육 의 사각지대에 놓여있는 교육 소외 계층인 다문화 자녀들이 중요한 사회적 이슈로 급부상하였다. 본 연구는 다문화 가정에서 성장하고 있는 아동 및 청소년들의 문화정체성을 형성하는데 도움을 줄 수 있는 무용교육 프로그램을 개발하고 적용함으로써 프로그램의 신체적, 심리정서적, 사회문 화적 영역에서의 교육적 효과를 입증하는 것이 목표이다. 다문화 아동 및 청소년은 서울 및 경기 도에 거주하고 있는 북한이탈가정 및 국제결혼가정 자녀 22명을 대상으로 하였으며, 자아발견과 예술표현, 의사소통 등 세 가지의 주요 목표를 위해 개발된 된 무용교육 프로그램은 회당 60분, 총 10회기의 프로그램으로 구성되었다. 프로그램의 교육적 효과를 검증하기 위해 신체적 영역인 순간근력과 유연성을, 심리정서적 영 역은 반구조화된 설문을 통해, 그리고 사회문화적 영역은 AIPE-S를 통해 측정하였다. 연구결과 첫 째, 신체적 영역에서 순간근력과 유연성 모두 통계적으로 유의하게 향상된 것으로 나타났으며, 둘 째 심리정서적 영역에서는 무용교육 프로그램을 접한 대부분의 참여자들이 앞으로 춤을 더 배워 보고 싶고, 어려운 춤을 배우고 난 후 자신이 자랑스럽게 느껴졌다는 의견을 보임으로써 자신의 문화에 대한 자긍심과 자신감이 형성되어 타인 앞에서 춤을 추고 싶은 욕구가 생기게 되는 긍정 적인 변화를 발견할 수 있었다. 마지막 셋째, 사회적인 영역의 경우 급우에게 응답(FB) 요인을 제 외하고는 프로그램에 참여한 교사와 아이들 간의 의사소통이 이전보다 통계적으로 유의한 수준에 서 빈번해진 것으로 나타났다.

미생물 발효에 의한 녹차 추출물의 쓴맛 감소와 관능성 개선을 위하여 식품으로부터 분리된 미생물을 이용하여 녹차 추출물을 발효시킨 후 catechin 성분 분석과 관능검사를 실시하였다. 다양한 발효식품으로부터 분리된 100종의 미생물을 2, 4, 6, 8, 10%(w/v) 녹차 추출물에 배양하였을 때 2%와 4% 녹차 배지에서 최대 생육도을 나타내었다. 녹차 추출물 발효액의 HPLC에 의한 catechin 종류별 분석 결과 epigallocatechin gallate(EGCG), epigallocatechin (EGC), epicatechin(EC)는 발효에 의해 함량이 급격히 감소하였고(EGCG : 125.45→65.42 μg/mg, EGC : 85.96→38.03 μg/mg, EC : 25.64→13.84 μg/mg), gallocatechin gallate (GCG)와 gallocatechin(GC)의 함량은 급격하게 증가하였다(GCG : 7.79→85.22 μg/mg, GC : 9.46→64.59 μg/mg). 발효 후 galloyl residue를 가지는 cathechin(EGCG, ECG, GCG, CG)의 함량이 상대적으로 작은 값을 나타낸 유산균 11주를 선정하여 녹차 추출물을 발효시킨 후 관능검사를 실시한 결과 Lactobacillus plantarum 62901과 Leuconostoc pseudomesenteroides K200132가 전체 기호도 조사에서 가장 우수한 결과를 보여주었다. 기호도가 좋게 나타난 샘플의 맛 패턴 특성을 살펴보면 구수한 향미는 강해지고 상대적으로 풀 비린 향미와 쓴맛이 낮아졌음을 확인할 수 있었다.
