  • This study was intended to analyze the visitors' awareness of the cultural asset value of Marsh Plants of Daesong-ri, Haman (Natural Monument 346) as well as the requirement for use and management of the only marsh designated as a National Monument in order to provide the implication for future management. The result of the analysis showed that the public awareness and the awareness level of the natural monuments were low and that the motivations for visiting were the experience and education of nature, rest and leisure, and experience of the cultural heritage, in that order. The analysis of motivation for visiting according to the awareness level showed that the group with a high awareness level of the Marsh Plants or the group that thought highly of its cultural asset value tended to visit it more for the experience of nature or the experience of the cultural heritage than for simple resting. For usage, the visitors required the basic amenities such as guide board and the more active promotion. They also preferred the discovery of traditional resources using the marsh plants and the experience of nature. Both local residents and outside visitors pointed out the lack of systematic management policy and lack of communication with local residents as the main problems. They recognized that the policy that balanced the preservation and usage through the cooperation of various stakeholder including local residents must be established and applied in the field to ensure proper management.

  • Fate of fenitrothion aerially sprayed to control pine wood nematode (Bursaphelenchus xylophilus) was studied in a forest of Haman area. And the monitoring of fenitrothion was conducted in a stream flowed from forest area of Gijang sprayed fenitrothion. Fenitrothion 50% EC was diluted 100 times and applied two or three times using helicopter in Haman and Gijang, respectively. Average fenitrothion deposits on forest floor ranged from 6% of standard aerial application rate. Following to the second application, fenitrothion deposits in the pine needle ranged from 0.6 to 0.9 mg/kg and then rapidly decreased to 0.01 mg/kg after 109 days. Deposits on the plant washed off by rainfall and reached to soil surface was 1.3% of the application rate. All of fenitrothion on the ground resided in the forest floor covering the soil surface, where fenitrothion residues were decreased to a tenth at 109 days after the second application, but they were not detected in sol beneath it. And the only low level of fenitrothion residues, 0.0009 mg/L, was detected in runnel of the experimental forest just after aerial application. The concentration of fenitrothion in effluent from Gijang area was less than detection limit (0.0001 mg/L) during the entire period.

  • 낙동강은 4대강 살리기 사업에 의해 8개의 보(상주보, 낙단보, 칠곡보, 강정보, 달성보, 합천보, 함안보)가 하천 내에 건설되고 약 4억톤의 준설이 실시되면서 지형적으로 막대한 변화를 맞이하게 된다. 낙동강은 상류의 안동댐 및 임하댐에서 방류수, 중류의 구미 및 대구 등의 오염원 그리고 하류의 남강에 의한 영향 및 낙동강 하구언에 의한 정체에 의한 영향으로 지역적으로 수질 및 수리 특성이 서로 다르게 나타나고 있다. 낙동강에 건설되는 수중보들 또한 이러한 유입 및 경계 조건에 따라 서로 다른 수질특성을 나타낼 것으로 판단되며 이에 대한 영향을 미리 예측하고 발생 가능한 악영향에 대한 대안을 수립하는 것이 중요하다고 본다. 본 연구에서는 낙동강의 4대강 사업에 의한 지점별 및 시기적 영향을 정확하게 분석하기 위해 3차원 수리동역학 모델 EFDC와 수질모델 WASP을 연계하여 사용하였다. 연구대상지역은 안동댐 방류지점에서 낙동강 하구역까지의 총 334km의 지역을 포함하였으며 하천의 폭 방향, 수심방향 및 흐름방향에 대하여 3차원으로 격자를 구성하여 하천을 표현하였다. 수리 및 수질 보정에 필요 한 입력자료는 국토해양부 및 환경부 등에서 발표 된 자료를 이용하였으며 2007년을 기준으로 모의를 실시하였다. 4대강 살리기 사업에 의한 8개의 보 건설 및 낙동강 전역의 준설의 영향을 예측하여 사업 전 및 사업 후로 각각 구분하여 비교하였으며 사업 후 체류시간의 증가와 준설로 인한 수심증가에 따른 복합적인 원인에 의해 수질에 영향이 미치는 것으로 나타났다. 사업 후 낙동강의 각 수중보 출구 부근 지점에서 예측된 수질 특성은 사업전에 비하여 $BOD_5$는 전반적으로 감소하나, TN 및 TP 는 유사한 특성을 나타내었다. 그러나 Chl-a 농도는 상류와 중류에서는 체류시간의 증가로 증가하는 경향을 나타내었으며 이는 수질이 양호한 상류 지역에서 특히 큰 차이를 나타내는 경향으로 분석되었다. 그러나 낙동강 하구언 지역은 Chl-a 농도가 사업에 의해 약간 감소되는 경향을 나타내어 여타 구간과 다른 경향을 나타내었다. 이는 낙동강 하류의 Chl-a 농도가 이미 매우 높은 상태에서 체류시간에 의한 성장 촉진 보다는 수심증가로 인한 광량제한 효과가 더욱 지배적으로 나타난 것에 의한 영향으로 추정된다.

  • This study is for finding a geoscientific factor for clarifying the source soil of the ancient earthenware finding. The used samples were the earthenware, soil and rocks, which were collected at the Gyeongju, Gyeongsan and Haman area. The chemical and mineralogical study for the samples were carried out for understanding the change of mineralogical and chemical composition among them. The mineralogical compositions of the earthenware are different from those of the soils from the surrounding area, which suggests that the mineralogical approach for clarifying the source soil of the earthenware should be difficult. Major element compositions of the earthenware also are different from those of the surrounding soils, which suggests that the comparison of the chemical composition using the major elements might be difficult for deducing the source soil of the earthenware. However, PAAS-normalized rare earth element (REE) patterns and Nd model ages among the rock, soils and earthenware from the same sampling sites show similar characteristics one another compared to those of the major element compositions. Nd-Sr isotopic systematics among the earthenware, soils and rocks also show a close relationship. Our results suggest that REE and Nd-Sr isotope geochemistry might be more useful than the other geochemical technique in clarifying the source soils of the ancient earthenware.

  • This study was conducted to determine the soil chemical properties and microbial flora of platycodon and their effect on rhizome rot incidence. Sampling sites were Keochang 4, Kimhae 7, Haman 6, Chinju 6 and Koseong 3 fields in Kyongnam province and Hongcheong 6 fields in Kangwon province. The root disease incidence rate was in the order of Haman 56.8%, Hongcheon 52.5%, Kimhae 36.7%, Koechang 35.3%, Chinju 32.3%, Koseong 30.0%. The yield at the Chinju 36.17 Mg/ha was higher than that of Koseong 25.00 Mg/ha, Kimhae 13.57 Mg/ha, Koechang 11.75 Mg/ha, Haman 9.50 Mg/ha, Hongcheon 5.24 Mg/ha. The soil K, $NH_4-N$ content and EC value of injury root were higher than those of normal root. The root CaO content was positively correlated with yield $Y=20505X-367.9(R^2=0.129^{\ast})$. The Fe and Zn content of normal root were higher than those of injury root, while the T-N, $P_2O_5$ and $K_2O$ content of normal root were lower than those of injury root. The population of bacteria, actinomycetes and bacteria/fungi ratio increased in soil of normal root, but that of fungi decreased.

  • The purpose of this study is to analyze the thermal comfort in Yeongnam area using climatic data and GIS data in order to determine regions necessary to improve thermal environment policies. The results of the calculated PET show that Daegu city is high and Bonghwa-gun is low compared to other regions. PET was compared with the typical classification according to regional characteristics. As a result, PET value of rural areas such as Changnyeong-gun, Haman-gun and Goryeong-gun was high but Green space was too low compared to other rural areas. Yeongnam area was classified according to the value of PET using cluster analysis. As a result, more low grade areas show that green space ratio was low and facility area was high. It is determined that there is a relationship between thermal comfort and land cover. The thermal comfort evaluation map in Yeongnam area will be useful for urban planning in order to establish a sustainable city in climate change.

  • The purpose of this study was to examine the levels of the subjective oral health awareness of local residents in the city of Changwon and Haman county in an effort to lay the foundation for the development of customized local oral health education programs. The 2015 community health survey data were used, and the data from 864 residents in Changwon and from 719 dwellers in Haman county were analyzed. The Changwon residents brushed their teeth after lunch more, received more oral checkups over the past year and had more scaling experience. The Haman residents had more experience of not receiving dental treatment. The subjective health awareness, subjective oral health awareness, chewing difficulty and periodontal health of the Haman dwellers were all worse, and all the levels of awareness were lower among the respondents who were older and who were diagnosed with hypertension and/or diabetes. The respondents who made use of dentures and who didn't brush their teeth after lunch had experience of not receiving dental treatment, and all the levels of health-related awareness were lower among the respondents who didn't receive dental checkups nor had scaling experience. To remedy the situation, efforts should be made to prevent and manage chronic diseases, and the establishment of a system that guarantees regular dental checkups and scaling is required. And the kind of environments that everybody can receive dental treatment when they want should be prepared. In order to change negative awareness, necessary measures should be taken to provide oral health education that is not temporary but sustainable and tailored to local characteristics and different life stages.
