The polycyclic aromatic hydrocarbons(PAHs) content in sewage sludge was determined by gas chromatography linked to ion trap mass spectrometry(GC/ITMS) with five deuterated PAHs as internal standards. The minimum detection limit was from 1.66 to 7.14 pg for individual PAH by GC/ITMS. For determining total PAHs(ΣPAH) in sewage sludge 84 samples from 74 waste water treatment plants in whole country were analyzed. The average content of ΣPAH for whole samples was 3,289±3,098 ㎍/kg, and ranged from 142 to maximum 20,102 ㎍/kg. According to the number of population of the city, the areas were classified as five regions, ie. big, large, middle, small, and rural area in which the waste water treated plants were grown. The contents of PAHs were 4,689±5,503, 5,839±6,401, 3,725±2,053, 2,237±2,069, and 2,475±1,489 ㎍/kg, in big, large, middle, small, and rural area, respectively.

The effect of low-intensity ultrasonography on dislocation of the patella and fracture healing is controversial, and current management of that does not generally involve the use of ultrasound therapy. Nine patients with dislocation of the patella were treated with low-intensity ultrasonography(l5 mW/㎠, 1∼3.3 MHz) per 10-15 min/days, with an interval of 3 days during the last 3 weeks, at Family Animal Hospital(in Kunsan city). Ultrasound therapy may be beneficial to dislocation of the patella and healing. This finding is of considerable importance in that treatment with a low-intensity pulsed ultrasound signal may reduce healing time and could yield substantial cost savings and decreases in disability associated with delayed healing of dislocation of the patella.

The purpose of this research is to find the relationship, leader-employees communication, job satisfaction of sports center employees. To attain the research objective, this study reviewed the previous literatures and derived the research model variable. Consideration and initiating structure were used as the leadership dimension. The subject in this study were 263 employees, who were selected by random sampling form 6 sports centers in Kyonggi Province at Suwon, Pundang. The collected data were handled by reliability analysis, t-test, one-way ANOVA. correlation analysis and regressoin analysis. The finding of this study were as follows: First, official communication, unofficial communication, and job satisfaction are positively related with both dimensions of leadership-consideration and initiating structure. Second, free of official and unofficial communications, and ioh satisfaction are different according to leadership type. These results showed a mere clerk's significant effected by leadership style. So sports center administrator need to more human care about a mere clerk. Third, the relationships between leader-employees official communication and employees job satisfaction in sports centers are different according to leadership type. Especially official and unofficial communications were effected job satisfaction. so role of communication were very important things. If employees were not offer constant information, customers were negatives effected not only sports leaders and sports centers but also repurchasing faith. Fourth, official communication between a sport center leader and employees in sports center is positively associated with unofficial communication for all leadership types. The employees need to awareness of steady to learn exercise knowledge, teaching skills, if not members are diffidence not only sports leaders but also sports center's disagree role of positive recognised. Also the free of unofficial communications are able to satisfied their work too.

강릉시 시범 공설묘지 조성사업은 경사 30˚ 의 표고차가 심한 산지를 절 · 성토하여 계단식 묘역단을 조성하는 공사로 수직고 15m이상의 대절토 및 성토부가 산재하고 있다. 특히 묘역단장후 주변 유입수 및 표면 유출수에 의한 비탈면 붕괴, 묘역단 유실 등의 피해가 발생할 경우 보수 또는 보강이 사실상 어려운 실정이며, 사회적 여론으로 확대될 가능성이 크므로 비탈면 보호에 필요한 녹화공법을 검토하였다. 구체적인 연구내용으로는 설계도면 및 현장답사를 통한 문제 비탈면 추출, 비탈면의 물리적 특성과 식생의 생육상황 파악, 비탈면 주변부의 식생조사와 유용식생 선발, 비탈면의 토양조건 분석 및 비탈면 토사의 기본물성 조사 등이며, 이를 기초로 하여 비탈면 현황 및 문제점을 파악하고, 그 대안을 제시하였다. The construction of a public cemetery in Kangnung city includes terraced graveyard with cutting or banking in mountain which has severe altitude differences with a slope of 30˚. Therefore, there are scattered cutting and banking sections with vertical height more than 15m. Especially, if the slope failure or the loss of a graveyard happens after graveyard establishment due to surface flow and inflow around, it is difficult to repair, causing serious public censure. Accordingly. revegetation works were examined that need protection of slope. The specific content of the study was the selection of slopes requiring special care through blueprint and field investigation the measurement of the physical property of slope and the situation of vegetative growth, the investigation of vegetation in slopes and the selection of vegetation, and the analysis of soil condition of slopes and the physical condition of slope sediment. On the basis of investigations some alternatives were proposed.Key words: public cemetery, slope protection works, revegetation works

본 연구는 주민참여예산제도 활성화 방안에 대한 요인을 도출하고 도출된 요인을 관련 공무원과 주민참여예산 위 원들의 설문조사를 통해 실증분석 하고, 또한 인천 남구 주민참여예산제도 운영에 대한 분석을 하였다. 연구결과 주민참여예산에 관한 요인은 ‘주민참여예산제도 기반형성’, ‘주민참여예산제도 성공요인’으로 구분됨을??확인하였고 이들 차원과 주민참여예산제도 시행효과의 인과관계와 각 요인에 대해 관련 공무원과 주민참여예산??위원들 두 집단이 차이가 있는지를 살펴본 결과 주민참여예산제도 기반형성과 주민참여예산제도 성공요인이 주민 참여예산제도 시행효과에 통계적으로 유의하게 나타났다. 또한 각 요인에 대한 관련 공무원과 주민참여예산 위원 들 두 집단에 대한 차이분석 결과 통계적으로 유의하게 차이가 있음을 확인하였다. 추가적으로 공무원과 주민참여 예산 위원들 각각 회귀분석 비교분석 결과 공무원은 주민참여예산제도 성공요인을 중요하게 생각하고 있으며, 위 원들은 기반형성 구축이 주민참여예산제도 시행효과에 더 중요하게 영향을 미치는 것으로 인식하고 있다, 주민참 여예산제도의 활성화를 위해서는 참여가치에 대한 공감대, 지역사회나 관련조직의 의견수렴, 교류를 위한 네트워 크 구축 등의 기반형성과 주민참여예산제도의 범위를 예산편성에서 예산 전반의 참여권한 확대가 필요하고, 공무 원의 적극적인 지원 활동 등 주민참여예산제도 성공요인 관리가 필요하다. This study derived factors related to the activation of citizen participatory budgeting, analyzed the factors??positively through a questionnaire survey of involved civil servants and participatory budgeting committee??members, and made analysis of participatory budgeting system for operation in the Incheon Nam-Gu area. According to the results of this study, factors related to participating budgeting were largely divided into??‘footing of citizen participatory budgeting’ and ‘success factors of citizen participatory budgeting.’ In the??results of examining the causal relationship between these dimensions and the effect of citizen participatory??budgeting system and seeing if there was any difference in each factor between involved civil servants and??participatory budgeting committee members, footing of citizen participatory budgeting and the success factors??of citizen participatory budgeting were statistically significantly correlated with the effect of citizen participatory??budgeting sysytem. In addition, a statistically significant difference was observed in each factor between??involved civil servants and participatory budgeting committee members. In additional comparative regression??analysis between civil servants and participatory budgeting committee members, civil servants attached more??importance to the success factors of citizen participatory budgeting, but committee members considered the??footing of the system more important for the effect of citizen participatory budgeting. What are required for the??activation of citizen participatory budgeting system are consensus on the value of participation, opinion??collection from communities and related organizations, construction of networks for exchange, and the??extension of the scope of participatory budgeting from budgeting to the whole range of budget?related areas.??What is more, the success factors of participatory budgeting including civil servants’ active support need to be??managed properly.

CC Chemokine CKβ8의 발현 조절 물질 탐색 및 저해활성 물질 분석

김탁용,이태훈,백남인,정대균,김지영 경희대학교식량자원개발연구소 2005 硏究論文集 Vol.24 No.-

CKβ8은 CC 케모카인의 부류에 속하는 사이토카인의 일종으로, 단핵구, 호염구, 호산구, T 림프구, 자연살해세포, 수지상세포 등의 화학주성물질로 작용하는 것으로 알려져 있다. CKβ8은 염증반응 및 혈관신생 등과 같은 여러 가지 생체 반응에 역할을 하는 것으로 알려져 있다. 본 논문에서는 사람 CKβ8 유전자의 전사저해 물질을 선별하기 위하여 CKβ8/Luc 유전자를 발현하는 세포주를 확립하였다. CKβ8 유전자의 전사시작점에서 -299 부터 +10 프로모터 부위를 PCR에 의해 얻은 다음 포유세포 발현 플라스미드에 클로닝하였다. CKβ8/Lvc 유전자는 U937 세포내에서 PMA에 의해 10배 이상 발현이 증가한다. CKβ8/Luc 발현 U937 세포주는 식물 추출물에서 전사 저해제를 탐색하는데 이용되었다. 46 개의 식물 추출물 중에서 6개가 90% 이상 CKβ8/Luc의 전사를 저해하였다. 이들 물질에 대해 세포 독성 실험을 수행한 결과 그 중 한 개만이 세포 독성이 거의 없는 것으로 나타났다. 이 추출물은 붉나무에서 얻은 추출물이며 이 식물 추출물은 염증관련 질환에 대한 가능성이 있는 치료제로 이용될 수도 있을 것으로 추측된다. Ckβ8 belongs to a family of CC chemokines, which is known to act as a chemoattractant for monocytes, basophils, eosinophils, T lymphocytes, NK cells, and dendritic cells. CKβ8 is known to play roles in various biological processes such as inflammation and angiogenesis. In the present study, we developed U937 cell line expressing CKβ8/Luciferase fusion gene for screening of transcriptional inhibitors for human CKβ8 gene. Genomic sequences that contain CKβ8 promoter region from 299 to+10 nucleotide from the transcription start site was amplified by PCR and cloned into mammalian episomal plasmid. The CKβ8/Luc fusion plasmid was introduced into human promonocytic U937 cells and selected for stable U937 cells expressing the fused reporter gene. The expression of the fusion gene was induced by more than 10 folds upon treatment of phorbol myristate acetate. The stable U937 transfectant cells were used for searching transcriptional inhibitors for human CKβ8 gene from plant extracts. Among 46 plant extracts tested, six extracts exerted more than 90% inhibition of PMA-induced CKβ8 transcription. Cytotoxic tests demonstrated that one of extracts, which was extracted from Rhus chinensis Mill, had little cytotoxic effect. The extract may be used for developing a potential therapeutic agent for inflammatory diseases.

There is a strong tendency for the firms to increase the employment level of non-regular workers under the rapid changes in human resource management environment. However, the research on non-regular workers is scarce, and more studies need to be conducted to provide human resource managers for guidance in employing the non-regular workers. The purposes of this study are (1) to describe the human resource management practices as applied to the regular and non-regular hospital workers, and (2) to identify the problems associated with the employment of non-regular workers, thus providing the baseline data for drawing the suggestions for improvement. The sample of this study is 26 general hospitals in Pusan-Kyungnam region. The data were obtained through questionnaires and interviews with the managers in human resource management department. The results of the study are as follows: (1) The average proportion of the non-regular workers to total employees in the responding hospitals is 6.15%, which seems to be lower as compared to the national macro figure. (2) The major reason of employing non-regular workers was found to be labor cost savings, (3) The non-regular workers on the whole receive poorer treatment than regular workers in terms of human resource management including wage and benefits. On the basis of above results, the problems and suggestions for improvement were discussed in the conclusion.
