Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

1980年代 以後의 農村社會運動의 性格과 方向

尹畯相,申尹澈 公州大學校 地域開發硏究所 1992 地域開發硏究論叢 Vol.1 No.1

The purpose of this study is to explore the characteristics of the Rural Social Movement since 1980s. This study were carried out through the review of literature. The major findings of the study were that 1) There have been much possibility to break out social movement on a large scale in rural society on account of rural society having the social structural factors(the economic disharmony, the status discordance, the difference of cultural goals and institutionalized means) and the psychological factors(frustration, a sense of alienation). So, we can prescribe the rural society to the situation of Anomie. 2) The characteristics of Rural Social Movement are to search for not only the economics interests but also the improvement of social, political, economic status and rights. So, the farmers formed the movement organization to participate social reformative changes. 3) The Rural Social Movement has been sloped in the preliminary stage(reconizing their problems), the popular stage(spreading their prolems) and the formal stage(forming movement organization). But not steped in the institutional stage(being systematic group movement) yet. The followings are recommended for improvement of rural social movement. 1) The movement organization must have resources such as organized power, leadership, fund, legitimacy for mobilization, supports from the outside. 2) The rural social movement policies must be developed and programmed by the farmer's needs and it must be allied with other social movement groups. 3) The rural social movement pratices must be changed from the out of system by using violent acts and stay-in strike to the within of system by sending their representatives to the national and local assembly.

몇가지 植物의 棲息地 造成에 關한 硏究

윤종선,김익환,신세균,심우경,이철희,신영철 韓國植物ㆍ人間ㆍ環境學會 1999 인간식물환경학회지 Vol.2 No.2

종의 棲息密度가 낮아지고 있는 하늘나리, 섬초롱, 자란 3종의 식물을 인위적으로 棲息地를 造成하기 위하여 국립공원 속리산 등산로변 標高 200m, 400m, 600m 지점에 150주식 종당 450주를 조직배양 및 분주에 의하여 육묘 된 묘를 이식하여 생존상태 및 棲息地 造成의 가능성을 2년에 걸쳐 검토한 결과는 다음과 같다. 1. 造成 棲息地의 토양의 理化學的 造成은 pH 5.2∼5.6, 유기물 함량 29∼54g/㎏, CEC 9.4∼11.5㎝ mol(+)/㎏으로 산성을 띠고 있었으며, 유기물 함량은 높은 편이었고, 염기치환용량은 낮았으나 비교적 우리나라 典型的 山地土壤의 理化學的 造成과 유사하였다. 2. 棲息地內 생장기간의 投光率은 標高 200m 지역은 10.8∼11.6%, 400m lw역은 10.8∼11.4%, 600m 지역은 11.0∼12.8%로 식재식물의 生長環境에 부족한 상태였다. 3. 식재 식물 수는 식재 후 활착율은 3종 모두 양호하였으나, 점차 감소되었으며, 특히 자란의 감소율이 높았다. 감소의 원인을 분석한 결과 하늘나리, 섬초롱, 자란 모두 굴취나 절취의 피해가 많았으며, 특히 자란은 凍害에 의한 枯死가 1년차 72∼86주, 2년 차에서 19∼35주로 조사도어 자연상태에서의 越冬은 어려운 것으로 나타났으며, 집중호우에 의한 流失도 감소의 한 원인이었다. 4. 식재식물의 생장상태는 불량하였는데 이는 投光量 부족으로 판단되어 棲息地造成時에는 錄陰期 投光量에 대한 사전 검토가 중요한 요인으로 나타났다. 5. 개화율은 섬초롱과 자란에서 높았으며 標高가 높을수록 개화기는 2∼4일 늦어지고 휴면기는 빨라지는 경향이었다. 식물 棲息地 造成時에는 造成 식물의 생장에 적합한 토양, 光環境 등을 고려한 위치 선정이 중요하며, 上層林에 의한 遮光으로 下層 초본식물 遷移速度가 빨라짐으로써 光環境 개선을 위한 上層林의 間伐, 周邊樹種의 更新이 요구된다. In order to make the artificial habitats of Lillium concolor, Campanula takesimana and Bletilla striata that the number of plant became sparse, 150 plants per species were transplanted at the region of 200m, 400m and 600m above sea level. And the growth of plants and the potential as habitats creation were analyzed. In the physical and chemical properties of soils in the there, soil pH was 5.2 to 5.6, organic matter content was 29 to 54g/㎏ and cation exchange capacity(CEC) was 9.4 to 11.5㎝ mol(+)/㎏. The transmittance rates of sunlight of the habitats during the growing periods were 10.8 to 11.6% in the 200m region, 10.8 to 11.4% in the 400m region and 11.0 to 12.8% in the 600m region. These transmittance rates were deficient for normal growth of plants. After the plants were transplanted, the survival rates of three species were high in common but the rates decreased gradually. Especially the decrease rate was high in the Bletilla striata. The causes of decrease were digging and cutting by climbers, sweeping asay by rainfall and freezing damage. Especially, the cold tolerance of Bletilla striata was weak in the natural condition. The growth of planted plants was poor, and it was assumed that the reason was shortage of sunlight transmittance. The flowering rates were high in the Campanula takesimana and Bletilla striata. And as the elevations were high, the flowering was later by 2 to 5 days but the dormancy was earlier. In the artificial making of plant habitats, the growth environment of plants have to be considered to choose the suitable region. And, because the habitats are shaded by the trees and bushes, the thinning of trees and the change of species are needs to improve the light transmission.

The purpose of this thesis is to examine the practical uses of Electronic Commerce and hardships of trading companies in Busan, and in doing so, propose several suggestions to improve their exports by using EC. According to this survey, many trading companies aggressively make use of EC in the field of abroad market survey, advertisement but make little use of EC in credit inquiry, offer and acceptance, formation of contract, payment, claims and so on. The greatest result to get appling Electronic Trade were abroad market survey, abroad advertisement and marketing, and reducing the export-import related time and charges and so on. And in implementing Electronic Trade, there are some obstacles as follows; a shortage of a specialist in performing Electronic Trade, insufficient of policy support and reliable payment system, risk of individual information leakage, and lack of reliable certificate authority. Therefore, in order to facilitate Electronic trade, it is required to improve various international laws and regulations, promote the trade leads sites, establish global certificate authority, global electronic payment systems and global electronic trade network, and develop training expert programing related to Electronic Trade.

글로벌 전자무역거래가 원활하게 수행되기 위해서는 원스톱의 지원시스템이 구축되어야 함에도 불구하고, 지금까지 글로벌 전자무역과 관련한 효율적인 비즈니스모델의 개발에 대한 본격적인 논의는 이루어지지 못하고 있다. 이러한 점을 감안하여 본 연구에서는 글로벌 전자무역의 효율적인 비즈니스모델을 모색하기 위한 방만으로써 글로벌 전자무역네트워크의 구축방안을 검토하였다. 이를 위하여 본 연구는 현재 한국과 일본을 비롯한 아시아를 중심으로 추진되고 있는 전자무역네트워크 구축사업을 중심으로 글로벌 전자무역 네트워크의 구축에 따른 당면과제를 분석하고, 향후 글로벌 전자무역네트워크의 합리적인구축방향을 제시함으로써 글로벌 전자무역의 활성화에 기여하고자 하였다. The rapid diffusion of e-commerce throughout the world has accelerated the introduction of global electronic trade. The essence of global electronic trade is to flow and exchange data among the related parties-businesses and counties. The proper linkage of trade networks are the fundamental elements to implement global electronic trade. In order to create a better environment for global electronic trade development, It is necessary for the related parties to make fit their information systems with those of their trading partners. In this paper, We focus on global electronic trade networks, which is at the heart of global electronic trade. The paper is organised as follows. Section II considers significances and requirements of electronic trade and electronic networks. Section III considers current state of global electronic trade networks. For example, The electronic trade networks such as Pan-Asian e-Commerce Alliance, Korea and Japan e-trade Hub Project, and ASEM e-Trade Network are examined. In spite of the advantage of these global networks, these have various problems that should be solved for global electronic trade. Section IV concentrates on the problems and the prospects faced in global electronic trade networks. The paper concludes with a summary which highlights a number of the key issues concerning global electronic trade networks.

이철주,김성윤,김동건,유남재 江原大學校 産業技術硏究所 2009 産業技術硏究 Vol.29 No.B

This study has analysed actual overbreak, shotcrete rebound and the ratio between the actual quantity of shotcrete to designed shotcrete measured during a NATM tunnel construction. The measured shotcrete rebound was about 7.2% in average which was about half the allowable rebound (15%), showing shotcrete spraying was performed well. Based on the measurement of excavated tunnel shape, average overbreak was about 28.5 cm after tunnel excavation by drill and blasting method. This was about 260% of allowable overbreak. In addition, due to the rebound and overbreak actual amount of shotcrete used in the tunnelling work was about 116.5 % of the designed value. According to the field measurement the ratio of actual shotcrete to designed value showed some relation with standard support pattern, but the size of overbreak did not show the correlation with standard support pattern. Hence current design specifications stating the size of overbreak based entirely on standard support pattern should perhaps be reestablished. The insight into the design guideline regarding overbreak and shotcrete

申尹澈 公州大學校 地域開發硏究所 1992 地域開發硏究論叢 Vol.1 No.1

The objectives of the study were 1) to review the present situation and problems and 2) to search further development directions in the development work of Rural-industrial district. This study was carried out through literature review. The major findings of this study were as follows; 1) In order to develop and activate continually the Rural-industrial district, the manpower supply-demand relaction and the rural manpower utilization must be achived. In point of the rural manpower utilization, it is important not only growing the factory working ratio for the enterprises in rural-industrial district but also growing technical skilled manpower for the qualitive supplement of rural manpower. 2) Rural-industrial district development work must be carried out in terms of a link a chain of intergrated community development programs. So, rural area can be activated a settlement living area and a base of economic activity. And the shortage of manpower of rural-industrial enterprises can be solved basically. 3) In order to cope with the radical changes of industrial environment by the open-door policy and internationalization, rural-industrial district development stratigies must be changed. In the beginning, rural-industrial district development work was set out from farming income increasing. Now we must have aims to leaving out from petty farming and employment promoting of rural living. And rural-industrial district must be become a main location source of small and medium enterprises in rural-industrial district. So, we can achived macro goals by means of a balanced community development.
