  • The purpose of this study is to understand the realities and the subject of environmental management for small and medium-sized companies in Gwangwon area, through surveying the present status as to acquiring the certification of ISO14001, and to seek for a plan to facilitate environmental management. Given summarizing key results, those are as follows. First, while the number of companies in our country which acquired the certification of ISO14001, amounts to 1,215 businesses as of April of 2003, the number of small and medium-sized companies in Gwangwon area which obtained the certification of ISO14001 reached only 26 businesses, the lowest level among metropolitan municipalities. Second, for the reason that companies who didn't acquire the certification, strive not to receive the certification, it did present the point that' costs to be needed in acquiring and maintaining the certification are larger than practical benefit. Third, the biggest reason for either companies which did not acquire the certification of ISO14001 or companies which did (try to) acquire the certification of ISO1400, was, enhancement of a corporate image,' and the effect after a company who obtained the certification introduced the environmental management system, was also shown to be 'the improvement of a corporate image.' Fourth, many companies who acquired the certification of ISO1400 pointed out the response related to 'burden on document creation and costs' and 'lack of manpower' as problems when introducing the environmental management system. On the basis of major results of a study as the above, given presenting the subject and a plan for activating the environmental management of small and medium-sized companies in Gwangwon area, those are as follows. First, because most of companies who did not obtain the certification of ISO1400 have low recognition of ISO14001, it needs continuous and positive publicity, education and a training system. Second, it requires to carry out an educational program to nurture professional manpower due to lack of manpower relevant to environmental management, to expand payment of subsidies, to open exclusive-charge department and consulting contact, to have the relevant information be database and to develop software. Third, in order to make the certification obtained through inexpensive costs and simple procedures, it needs to positively consider the creation of public approval system for a small and medium-sized company, group approval system, industrial-complex approval system, and others.

  • The purpose of this investigation is to point out the physical fixation and stability of banking slopes of forest roads by invasion of trees. We investigated the situations of sediment discharge and coverage of invaded trees at banking slopes of forest roads. The coverage of invaded trees were calculated from crown injection based on the stable slope and was compared with length of slope, slope gradient, and passage years after construction of forest road. 1. We investigated on the sediment discharge and the invasion of trees at banking slopes, which were actually observed 8 forest roads of Kyonggi-Do and Kangwon-Do. 2. There was no physical stability of the banking slope due to the surface erosion and slope failure, but the tree invasions were active at the stable plots. 3. The length of slope was constructed to 4.0m to 61.0m and recent forest road was mainly constructed to the slopes longer than 30m. There was strong regional effect between the length of slope and the coverage of invaded trees and the above two factors were inversely proportional to each other. 4. There was no significant relationship between the slope gradient and the coverage of invaded trees and the slope constructed within the angle of repose showed the relatively high coverage of invaded trees. 5. There was no significant relationship between the passage years and the coverage of invaded trees in the same investigative region after the construction of forest road. But there was a gradually increasing relationship of tree invasion between above two factors. However, there was some limitation to expect the invasion of the tree species. 6. In the light of the above results, we suggest that the construction of forest road may need foundation work and vegetation work simultaneously for the physical stability to make the environment of tree plantation and that the reasonable increase of construction cost of forest road may be prior to the other factors.

  • We are interested in the PON which is easy to install and inexpensive to maintain, as it is a solution of the FTTH that is a core technology of the BcN access network. When a new ONU is connected, TDMA PON has a procedure called ranging that OLT measures the distance and allocates the equalized delay to it in order to provide the same logical distance to all ONUs. For the procedure, the OLT has to open a time window several times and already activated ONUs cannot transmit a data to the upstream during the periods. Accordingly, it is important to reduce the window size for saving the bandwidth and providing a user the service smoothly. In this paper, we investigate the ONU activation method of G-PON based on ITU-T G984.3 and suggest an advanced method(algorithm I) that minimizes the window size without information of ONU distance. The size can be reduced by calculating the pre-assigned delay obtained during Serial number state. Also, we compare it with another(algorithm II) with information of distance. As a result, the window size reduces to $50{\sim}90%$ for the algorithm I and 99% for algorithm II during the ONU activation process.

  • Recently, It became possible to transport freights and energy resources via Northern Sea Route(NSR) as global warming has been accelerated. As a result, all countries of the world and Korean local governments have had a struggle to take the advantageous position first in NSR development. However, this extreme competitions might have a negative effect on the national port industry and cause unnecessary social costs and economic losses. Therefore, the main target of this study is to find the most suitable port for NSR using AHP analysis. Most of the data was gained from previous literatures and public statistics and the weight of each factor was calculated by the result of expert survey. As a result, Busan port has the biggest competitiveness, followed by Yeosu Gwangyang, Ulsan and Incheon. From the result, this study suggested 3 possible scenarios. The first scenario specializing Busan port in NSR focuses more on developing the related businesses such as repair of ships, refueling, ship stores trade than attracting the more cargoes. the second is a strategy to make Ulsan port as a hub for energy resources, especially liquid cargo on NSR. the last is a mixed one to assign suitable roles to the ports according to their competitive capabilities.

  • The administration data of the national health insurance and health insurance bills were utilized in this study. The data of 485,953 patients who were at the age of 30 and up and used the out-patient departments of every medical institution located in some regions involving two southern and northern provinces once or more during a 184-day period from July to December, 2008. As a result of analyzing their Continuity of Ambulatory Care and factors affecting it, the following findings were given: The continuity of ambulatory care among the adult patients with hypertension in our country turned out to be on a high level(MMCI $0.96{\pm}0.13$, MFPC $0.96{\pm}0.12$). Given examining the outpatient medical-cure continuity level according to index, the averagely medical-cure continuity level was calculated to be high level with MMCI, $0.96{\pm}0.13$, and MFPC $0.96{\pm}0.12$. Thus, the tendency of visiting only one medical provider was high. The findings of the study illustrated that the average continuity of ambulatory care among the adult patients with hypertension in our country was on a high level, and it seemed that special care should be provided to patients with a low-level continuity of ambulatory care, such as women and elderly people aged 64 and over. The findings of the study are expected to serve as one of the barometers for the health care of patients with hypertension and for the performance of national hypertension management plans.

  • 본 연구(硏究)는 선물거래의 선진국이라고 할 수 있는 미국(美國), 영국(英國), 일본(日本)등을 대상으로 선물계약(先物契約)의 증거금변경(證據金變更)이 시장활동(市場活動) 즉 거래량(去來量), 미결제포지션(open interest), 가격변동성(價格變動性)에 미치는 영향(影響)을 만기별(滿期別)로 구분하고 또한 시계열(時系列) 현상(現狀)을 제거한 후 비교분석(比較分析)함으로써 이러한 분석결과를 토대로 우리나라가 주가지수선물을 도입하는데 있어서 차후의 증거금관리(證據金管理)에 대한 하나의 정책적(政策的) 방향(方向)을 제시(提示)하고자 하였다. 연구결과(硏究結果)를 요약(要約)하면 증거금(證據金)은 시장활동(市場活動)인 거래량(去來量)과 선물계약(先物契約)의 수요(需要) 즉 미결제포지션에는 상당한 영향(影響)을 미치나 가격변동(價格變動)에 미치는 영향은 미약하며 그러한 효과는 비교적 단기적(短期的)인 것으로 밝혀졌다. 아울러 그러한 효과는 국가간(國家間) 및 상품간(商品間)에 큰 차이 없이 거의 공통적(共通的)인 현상(現狀)임이 밝혀졌다. 구체적으로 본 연구가 시사하는 바는 연구결과(硏究結果) 중 증거금변경(證據金變更)에 따른 미결제포지션의 움직임을 거래량(去來量)과 연관(聯關)시켜 생각해 볼 때 증거금인하시(證據金引下時) 단기에 거래량이 유의적으로 증가하면서 동시에 미결제포지션이 유의적으로 증가하는 것으로 보아 증가되는 많은 거래량은 선물시장 참여자들이 새로운 포지션을 취하기 때문인 것으로 보여진다. 이러한 사실은 거래소가 증거금인하(證據金引下)를 통하여 잠재적인 시장참여자들의 비용(費用)을 낮춤으로써 시장유동성(市場流動性) 제고(提高)를 유도하는 경우 이러한 시도는 단기적(短期的)으로는 어느 정도 효과(效果)를 거둘 수 있음을 시준(示晙) 한다. 또한 증거금변경이 가격변동성(價格變動性)에 미치는 영향은 크지 않은 것으로 밝혀져 일반적으로 선물거래소들이 취하고 있는 증거금정책으로써 가격변동성을 관리하기 위한 증거금(證據金) 운용정책(運用政策)은 적어도 단기에 있어서는 어느 정도 효과를 보나 그 효과는 크지 않은 것으로 판단된다. 이러한 사실들은 증거금변경이 이루어지는 시점이 일반적으로 시장활동(市場活動)의 변화(變化)가 나타나기 시작한 후 1개윌 이내에 이루어져 왔다는 사실을 고려한다면 많은 선물거래소들이 취하고 있는 증거금관리정책은 비교적 단기적인 효과를 위한 것이며 그러한 정책(政策)들은 나름대로 소기의 목적(目的)으로 달성하고 있는 것으로 보인다. 끝으로 증거금변경이 선물시장활동에 미치는 효과의 국가간(國家間)의 차이(差異)가 없고 또한 상품간(商品間)에도 사실상 차이(差異)가 없다는 사실은 앞으로 선물시장을 개설할 우리나라의 입장에서 볼 때 선물증거금(先物證據金) 운용(運用)에 관한 정책수립시(政策樹立時) 금융선진국(金融先進國)의 증거금(證據金) 정책운용(政策運用)을 통한 시장관리(市場管理) 경험(經驗)을 어느 정도 참고할 수 있음을 시사한다고 할 것이다.

  • With the rapid development of information and communication technology, information exchange between ships and shore has become faster and more convenient, However, accessing ship information has also become easier and concerns about cyber security attacks are growing. When a ship suffers a cyber-attack, it may cause considerable damage and incurs enormous costs and time to repair. In response to this threat, the maritime industry now demands that a cyber security officer be assigned to each ship to take charge of cyber security management onboard. In order to reduce the damage cause by an attack and to respond effectively, a specialized training course for the ship's cyber security officer is required. The purpose of this study was to present a training course for the position of the ship's cyber security officer, and to highlight the necessity of amending current legislation, To this end, domestic and foreign trends, ship cyber security incident cases, and cyber security training courses were investigated, and based on the results a standard training course for a ship's cyber security of icer was developed. Additionally, recommendations on the related amendments to legislation ware established. The results of the study can be used as basic data to establish future training courses for cyber security officers.

  • This study aims to, looking from a standpoint of network, has investigated the shipping industry's B2B e-marketplace, the characteristics that can earn electronic trust from the users, and characteristics of the web-site. It has examined the mechanism whereby electronic trust be earned and how it affects web-site involvement and service transaction intention. Ultimately, The study attempts to make proposals whereby such trust can lead for a cooperative trading community in the shipping industry's B2B e-marketplace The Covalence structural equation modeling was designed and empirically tested for the shipping industry's B2B e-marketplace. The shipping industry employees were given questionnaires and data were analyzed. Except for perceived security of the three characteristic factors on the web-site, the perceived site quality and characteristics factors in operation only affected co-variables. Transaction Fairness was determined to be the most important factor among exogenous factors increasing electronic trust. With regards to transaction rules, if a transaction is beneficial only to one side, then no long term transaction will not take place. If the concerned parties properly recognize that transaction fairness is crucial to electronic transaction, then it will enormously contribute to successful operations of shipping e-marketplace. Also, Perceived efficiency in transaction also affects electronic trust. This reduces transaction costs and speeds up and simplifies the transaction process. It has reduced greater time and costs than existing off-line transaction, and would positively affect electronic trust. By making an open forum for participants to obtain information for transaction, they can gather useful information, and at the same time, the web-site operator can provide information, which, in turn, will increase electronic trust in electronic transaction. Furthermore, such formation of trust in electronic transaction influences shipping companies in such a way that they will want to continuously participate in the transaction, raising web-site involvement. The result of increased trust is that shipping companies in the future will do business with each other and form a foundation for continuous transactions amongst themselves. Consequently, the formation of trust in electronic transaction greatly influences web-site involvement and service transaction intention. The results of the study have again proved that in order to maintain continuous business relationship with the current clients, electronic trust in virtual space, which operates the shipping industry's B2B e-marketplace, is important for the interested parties.

  • To create and maintain comparative supremacy as a strategic tool of business, many organizations have introduced informational technology and system. By using this system, Some companies got a beneficial value for achieving organizational goals but others could not obtain their effectiveness and efficiency. In particular, a lot of organizations that tried to make strategic supremacy with e-commercial trade are under hard condition because of poor profit. It implies that it is essential to identify and analyse the consumer who uses e-commercial trade. This paper, therefore, focusing on internet shopping malls between business and consumer as one of areas of e-commercial trades, shows the difference between consumer expectation and performance. The results of this study are as follows: First, as for the significant difference of influencing factors to consumer satisfactions according to the types of internet shopping malls, there is a meaningful difference in consumer anxiety and internet usefulness, but not in consumer service. Prior to verify the differences in detail on consumer's anxiety and internet usefulness, we examined that there is any difference between expectation and performance. T-test was used for the variants of consumer anxiety and internet usefulness, and its meaningful probability was 0.000, which means that both showed statistically significant difference. Based on the results, we also found that regardless of the types of internet shopping malls, consumer expectation was greater than performance. although the difference between expectation and performance was not equal according to the internet shopping malls. Second, a regression analysis was performed to understand the relation between consumer service, internet usefulness, consumer anxiety, and consumer satisfaction, it was found that consumer service, internet usefulness, consumer anxiety had significantly effected on consumer satisfaction. Third, To verify the relation between consumer satisfaction and repurchase-intentions, intentions to spread out, Pearson correlation analysis was used. it was found that consumer satisfaction had positive effect on both intentions. This study has some limitations because of the shorts of money and time. since the sample of this study was consumers who have ever bought one or more products via internet shopping mall, this sample was appropriate. but the major parts of sample were college students, and the sample size was so small. therefore this results should carefully be generalized. For further study, it is required to select more precise samples and to include more variables.
