1994년 "유엔해양법협약" 의 발효로 새로운 국제해양법제도가 확립되면서 세계 각국은 통일적인 해상집법체제를 구축함으로써 관할해역에 대한 종합적인 관리를 강화하고 있다. 그러나 중국은 아직 전통적인 분산형 산업관리체제를 유지하고 있어 기존의 해상집법역량은 날로 확대되는 국가주권과 해양권익의 수호요구를 충족시키지 못하고 있다. 따라서 본 연구에서는 한 중 일 3국의 해상집법체제를 비교 고찰하고 중국해상집법체제의 주요 문제점을 분석한 후, 해경을 중심으로 한 통일적인 해상집법체제의 개선방안을 제시하였다.

This study was aimed to determine effects of soil organic amendment as plant growing media component on restoration of planting ground. The changes of soil physical and chemical properties and germination and growth of kentucky bluegrass (Poa pratensis L.) were investigated. For treatments, soil was excavated at depth of 0-50 cm (referred as S1) and at depth of 50-100 cm (referred as S2). Then the half amount of S1 soil was mixed with the soil organic amendment (coir dust 40% (v/v), bottom ash 25%, leaf mold 25%, vermiculite 5%, carbonized rice hull 5%) at a rate of 6% (v/v) (referred as S1CC) and also the half amount of S2 soil was mixed with the soil organic amendment at a rate of 6% (v/v) (referred as S2CC) on pot in a 16 cm diameter and 14 cm height. The experiment was replicated 3 times with 3 pots per replication in randomized block design, and 100 seeds were planted per pot. In results, there was no significant difference in soil pH among the treatments with a slight decrease in soil hydraulic conductivity. However, in the S1CC treatment, positive increases in soil chemical properties, including electrical conductivity, organic matter, phosphoric acid, total nitrogen, exchangeable cation, and cation exchange capacity. Also, the germination rate, plant height, and number of leaves were higher in the S1CC treatment than those in other treatments. These results suggest that the addition of organic amendment to the soil at depth of 0-50 cm might be proper for restoring planting ground.

The cut slope distributed in domestic, which have single horizontal extension over 200m and 50m of vertical height are classified into 2nd class facility by <Special Act On The Safety Management Of Structures>. Collapse of these cut slope occurs by thaw, rainfall, soil characteristics. Recently, frequency of small size cut slope collapse is increasing. Accordingly, central government partially revised <Special Act On The Safety Management Of Structures> with the contents of expansion of 2nd class facility's scope and standard and it is expected to be an effective maintenance and management measures of cut slope. Therefore, this study analyzed distribution type and characteristics of the national highway cut slope within the scope of relevant laws and regulations based on the status data of 2nd class facility (cut slope) to examine the maintenance status.

본 연구에서는 해부학적 영상 획득에 중추적인 역할을 담당함에 따라 전 세계적으로 검사빈도가 증가하고 있다. 하 지만, 환자가 받는 방사선량이 상대적으로 높아 적절한 관리가 이루어지지 않으면 과도하거나 불필요한 방사선 피폭으 로 환자선량을 증가시킬 수 있다. 이를 위해 특수의료장비로 지정하여 안전관리를 시행하고 있는 전산화 단층촬영용 장치의 항구성 시험 IEC 60601-2-44의 개정판에 대하여 문헌 조사하였다. 그리고 비교 및 분석을 통하여 새로운 요 구 사항에 대하여 알아보고자 하였다. 문헌 조사 결과 개정된 3판(3rd Ed)에서는 명확하고 강화된 기준값을 적용하고 있고, 2판에서(2nd Ed)의 한계점을 해결하기 위하여 합리적으로 개정되었다. 그러므로 현재 국내에서 적용하고 있는 IEC 60601-2-44 2판을 개정된 IEC 60601-2-44 3판으로 적용한다면 부적합한 의료장비로 인한 환자의 위해를 막 을 수 있을 것으로 사료된다.

The purpose of this study is to propose an appropriate method for marking out a boundary line of area damaged by aircraft noise. In an actual situation, there are many gaps between the boundary line of aircraft noise contour and the boundary line of an occupant of a house. Three cases faced in practice are considered in this study. Case Ⅰ is considered the land number together with sub-number. The Tong and Ban (the residential district number in Korea) are considered in Case Ⅱ. In Case Ⅲ, the configuration of ground is examined. The authors expect that the authority of aviation affairs should choose one of these cases and put in force in the near future.

The purpose of this study is to propose an appropriate criterium for proper sound insulation service preventing school classrooms from aircraft noise. The guideline of noise level for school facility by Korean school health law is less than Leq 55 which is less stringent than that of other countries. It has been reported that many students are annoyed and disturbed for their works when they are exposed to the noise level over Leq 55. It is desirable to modify this guideline of indoor noise level for school classroom. The noise level of classroom of which windows are opened was measured relatively high in case the school is located at the outside of the official area damaged by aircraft noise. In order to minimize the influence of aircraft noise on the school classrooms in the vicinity of domestic airport, it is necessary to improve the present criteria of WECPNL 75 for the establishment of the area damaged by aircraft noise from WECPNL 70.

In Korea, the System of search and rescue in water have came into force on the basis of the Korea Life Saving and Rescue Act. 1961. But It's a premodern administration law which is not fit for an international system of the search and rescue and become disconnected with reality in Korea. Recently the marine casualties occur frequently in Korea coastal area, therefore, we need to amend the 1961 Act. The amendment which is carried out by the Korea Maritime Police Agency is a provision to receive International convention(SAR, 1979). The amendment of this Act will give a epoch-making change to Korean policy of the life-saving and rescue, security to marine safety and contribution to National positon on system of "Search and Rescue". In this thesis, I propose a development scheme to be conductive to original task on "Search and Rescue" of International Convention in Korea Life Saving and Rescue Act(Amendment, 1994).t(Amendment, 1994).

The International Convention for the Prevention of Pollution from Ship, 1973, as modified by the Proto-col of 1978 relating thereto, well known as MARPOL 73/78, is probably the most important international agreement on the subject of marine pollution. The main purpose of the Convention is to reduce the total oil remaining on board vessel to minimum. MARPOL is a combination of different sets of rules on oil, chemicals, noxious substances in package forms, sewage and garbage as shown on each Annex. Since the Convention has globally set forth in 1973, it has amended so often whenever reasonable articles are requi-red by contracting states under guidelines of IMO. The amendments, for instance, have continuously perfo-rmed more than 8 times regarding articles, protocols, and five annexes because the original text was badly drafted as the control measures were expressed in general way. This paper, therefore, is intend to summa-rize a main point relating to each amendment, so that persons who have an interest in the Convention would be completely understand for practical implementation. Especially, for legislative purpose or annen-dement of domestic law, it could timely be contributable if specific consolidation and unified interpretations are followed with this paper. Consequently it is much more worth to study for preventing marine pollution from ship with tracing every moment whenever the Convention formally adopted through amending up-to-data.
