This study was conducted to determine the concentration of heavy metals and their characteristics in the bodies of 2,446 residents living near industrial areas from 2007 to 2015. The concentration of heavy metals showed diverse characteristics according to gender, food types consumed and period of residence. Especially, levels of cadmium and mercury were high in the urine samples of the group that had lived in the local area for a long time. In order to obtain more accurate results, it will be necessary to comprehensively study the influence and effects from such matters related to lifestyle, eating habits and levels of environmental pollutants.

This study obtained the following conclusions using the measurement results of indoor and outdoor PM10 with regard to cardiovascular disease patients in Cheongju-area in November 2020. Most of the PM10 has an I/O ratio of less than 1, which is an outdoor source. Since we measured once and twice time, Without the air purifier device’s working status, there were no concentration changes of PM10 in the first and second indoor areas. As for the concentration of PM10 according to the living environment, the distribution of PM10 is higher indoors than outdoors when the residential area is 30 m2 or more, and the outdoor PM10 concentration tends to be high when the distance to the road is within 50 m. The more time spent indoors, the higher the indoor PM10 concentration. The smaller the ventilation time and frequency, the longer the cooking time was, and the higher the number of cooking times, the higher the concentration of PM10 could be. The indoor PM10 contribution ratio through multiple regression analysis showed the possibility of increasing indoor PM10 as β = 28.590 when the time spent indoors was longer than 16 hours (p<0.05). The result regarding PM10 exposure reveals that PM10 can be inhaled not only indoors but also outdoors, and the subjects of this study appear to have lived indoors for about 16 hours or longer on a daily basis, which may affect their health regardless of gender.

This study investigated 180 students’ indoor environmental awareness of rest spaces and measured the indoor and outdoor concentrations of PM10, TVOCs, and HCHO in 8 rest spaces from October 2019. 89.4% of the students responded that they use rest spaces at least once a day and most of the respondents are using rest spaces in the university. The largest number of students responded to the tight space as the main cause of air pollution in rest spaces. 62.1% of the students answered they experienced health symptoms from using rest spaces. Among them, 32.5% said they experienced irritation symptoms of eyes, neck, nose, and 12.1% answered that they experienced headaches. Indoor PM10, TVOCs, and HCHO levels did not exceed indoor air quality recommendations nor the maintenance standard for multi-use facilities. Indoor PM10, TVOCs, and HCHO levels did not exceed indoor air quality recommendations nor the maintenance standard for multi-use facilities. According to the type of rest space, concentrations of PM10, TVOCs, and HCHO were higher among the closed-type than open-type rest space. Even if the concentration of pollutants is less than the environmental standard, continuous exposure may cause negative health effects. In addition, considering that 62.1% of the respondents experienced health symptoms, it is deemed necessary to take measures to manage indoor environments in rest spaces and to develop measures to reduce pollutants.

This study conducted a survey on environmental awareness and analyzed outdoor PM10 and heavy metals (cadmium, lead) for 60 local residents living in the Gwangyang national industrial complex from July 2019. 40.0% of subjects responded that local environmental pollution was serious. Especially, there was a high proportion of residents living near the industrial complex or roads where it was perceived that local environmental pollution was serious. The average concentration of PM10 in the outdoors of the houses was 10.95 μg/m3 and the average concentration of heavy metals in PM10 was 1.90 ng/m3 for Cd and 24.92 ng/m3 for Pb. Overall, the average concentration of PM10 and heavy metals revealed a tendency to be high in the houses located near the industrial complex or the roads. As a result of a risk assessment carried out, the cancer risk of Cd was estimated to exceed 106 in the CTE, RME and Monte Carlo analysis. These results suggest that the urgent implementation of specific environmental health education for local residents is necessary.

This study examined the relevance of impact factors using survey data, standardized mortality rates, and medical utilization rates of study subjects in the Namhae and Hadong regions. The study subjects were found to have lived in the area for more than 20 years, and in terms of lifestyle, they did not smoke, but the rate of drinking was high and showed little exercise. As a result of analysis through logistic regression analysis, it was found that angina pectoris, myocardial infarction and anemia were affected by exercise status, and allergic rhinitis disease showed significant results depending on the presence of smoking. The standardized mortality rate of men in chronic lower respiratory tract diseases in the Namhae and Hadong regions was higher than in the nation. In the case of allergic rhinitis, both men and women in Namhae were slightly lower than those in Nation, and in Hadong, both men and women were higher than in Nation.

In this study, 38 residents of the Jeonnam areas in Korea were assessed for their level of exposure to VOCs. The aim was to understand the difference in levels of indoor, outdoor, and personal exposure to VOCs (benzene, toluene, ethylbenzene) and a health effect assessment was conducted to determine whether there was any fatal cause from carcinogenic or non-carcinogenic elements from case and control group. Personal exposure to benzene showed a higher distribution than indoor and outdoor concentrations, and it was found that the average concentration of the case group was higher than that of the control group in all indoor, outdoor, and personal exposures. With regard to benzene, in the CTE, RME, and Monte-Carlo analysis, all subjects in the case group were seen to exceed the lifetime cancer risk of 10−6 defined by the US EPA and in the RME analysis the control group subjects were also seen to exceed the lifetime cancer risk of 10−6 defined by the US EPA. In the case of toluene, ethylbenzene on the CTE, RME, and Monte-Carlo analysis, the non-carcinogenic standard of 1 was not exceeded.

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).

최근 일본에서 독개미류(Solenopsis geminata, S. invicta)의 항구지역에 대한 집중 조사 및 방제를 실시하고 있다.한국에서는 남쪽 지방의 항구가 발생 가능 지역에 포함되어 있어 국내 침입여부를 확인하기 위한 조사를 실시하였다.부산항 지역을 대상으로 조사한 결과 3아과 10종의 분포를 확인하였다. 그 중 1종은 국내 미분포종인 Paratrechinalongicornis 였으며, 발견 즉시 발생지를 포함여 주변에 대한 약제살포 등의 방제작업을 실시하였고, 추후 발생여부를 계속 모니터링하고 있다. 현재까지 추가 발견이 없어 박멸에 성공한 것으로 판단된다.

Cette etude vise a reveler une verite du Nouveau Brutalisme des Smithson (Alison et Peter). Nous examinerons donc d'abord l'universalitf de leur oeuvre representatif, Ecole Secondaire de Hunstanton(projet, 1949; concours, 1950; construction, 1951-1954) et projet de Maison Soho a Londres(1952) comme un mouvement architectural. Et apres nous trouverons la faussete de leur but, realisation de l'ethique architecturale, sur ce mouvement en comparant les oeuvres des Smithson avec les deux constructions considerees souvent comme la categorie du Nouveau Brutalisme, la Calorie d'Art de l'Universite Yale(1951-1953) realisee par Louis I. Kahn(1901-1974) et le Centre Cuturelle de Georges-Pompodou(1971-1977) par Renzo Piano et Richard Rogers. En resultat, l'etique de Nouveau Brutalisme soutenue par les Smithson et defendue par Reyner Banham etait seulement pour cacher low limite architecturale et sa faiblesse. Ce mouvement etait aussi un mouvement personel plutot que general. On ne pourrait pas donc considerer les Smithson comme nouveaux brutalistes.

Cette etude vise a trouver I'intention originelle de Le Corbusier(1887-1968) dans les Maisons Jaoul a Neuilly-sur-Seine (1951-1955). En general, on regarde ces maisons comme no autre architecture do Le Corbusier ou un des oeuvres do Brutalisme International. Mais, en consideration du developpement architectural de Le Corbusier, les Maisons Jaoul a ete we des deux realisations de la maison economique en serie que Le Corbusier a etudiee pour la vie: l'un a ete l'Unite d'Habitation a Marseille(1947-1952) pour la cite verticale en serie et l'autre les Maisons Jaoul pour une cite horizontale en serie. Pourtant, ces maisons ne sont pas parfaites pour l'homme. Selon Marie Jaoul qui est une petite-fille d'Andre Jaoul, Le Corbusier a prefere l'harmonie entre la nature et l'architecture plutot qu'entre l'homme et l'architecture.

The National Institute of Environmental Research (3rd KONEHs) conducted a survey of 280 residents in Ulsan, Suwon and Asan, and the concentration of heavy metals in the blood and urine were also analyzed. In case of blood lead concentration, Ulsan 2.27 ㎍/㎗, Suwon 2.08 ㎍/㎗, and Asan 1.75 ㎍/㎗, the high peak in Ulsan, and the low peak in Asan. In case of cotinine concentration, Ulsan smoking(609.16 ㎍/g_ct) is higher than nonsmoking(74.07 ㎍/g_ct), as Suwon and Asan smoking(416.72 ㎍/g_ct, 903.21 ㎍/g_ct) is higher than nonsmoking(72.72 ㎍/g_ct, 18.06 ㎍/g_ct), smoking group is higher than nonsmoking group in all areas revealed statistically significant correlation(p<0.01). In considering results synthetically, these study results are an aid to constructing environmental health science-side heavy metal management measure education programs for normal residents.

한국에서 재배되고 있는 시호(Bupleurum falcatum L.)의 유전적 계통의 확립을 위해 시호(Bf), 참시호(BfC), 대전 삼도시호(BfJ) 및 수원 삼도시호(BfS)등 4계통을 대상으로 핵형분석을 통해 염색체의 다형현상을 비교하고, SDS PAGE를 이용하여 저장단백질의 양상을 분석하였다. 체세포 염색체 수는 3계통(Bf, BfC, BfJ)에서 2n=20, 1 계통(BfS)에서 2n=26으로 구분되었다. 염색체 1번은 2n=20 계통의 경우 차중부 염색체였으나, 계통 2n=26에서는 중부 염색체로 관찰되어 차이를 보였다. 계통 2n=20에서 2번, 3번 및 5번염색체가 다형현상을 보였으며, 한국에서 재배되고 있는 계통의 핵형은 일본에서 도입되어 재배되고 있는 대전 삼도시호 및 수원 삼도시호와 차이를 보였다. 이러한 결과는 세포유전학적으로 다른 2가지 이상의 계통이 한국에서 재배되고 있음을 보여주는 것이다. 종자에서 추출한 저장 단백질은 45KD 이상의 단백질에서 수적 차이를 보였으며, 2n=20의 계통에서 3개, 2n=26 계통에서 2개의 특이한 밴드가 관찰되었다.
