낙동강홍수통제소는 1987년 3월 개소 이후, 하천유량관리 업무를 체계적으로 하기 위해 1999년 8월 국가하천의 하천수 사용허가 업무가 우리 소로 이관되었고 2008년 4월 지방하천으로 확대되었다. 이로 인해 수문조사, 홍수예보 이외에도 하천유량 관리 업무의 제도적 개선을 통해 국기 물관리 전문기관으로서의 기틀이 마련되었다. 본 연구에서는 유역 중심의 합리적인 물사용과 물이용의 형평성을 위해 기존 국가하천 및 지방하천의 하천수 사용허가 자료를 현행하고 그 특성을 파악하려 한다. 조사 결과 낙동강유역 총 허가수리권 현황은 총 550건이고 허가량은 21.68백만$m^3$/일로 집계되었다. 그 중 농업용수가 전체 허가건수 중 약 70%, 전체 허가량 중 약 50%로 가장 높았다. 또한 하천법 상 하천수 사용 보고 대상자 건수는 전체 52%이나 허가량은 약 97%로 파악되었다. 요컨대 이번 연구를 통해 제고된 하천수 사용허가 자료는 실시간 낙동강 유역 물관리에 필요한 다양한 정책 의사 결정에 있어 기초자료로 적극 활용할 수 있을 것으로 기대한다.

In order to study on the improvement of gill nets and trap nets fishing for the management of fisheries resource in the coastal area of Yellow Sea, we have investigated the general present condition of those fishing, and the actual fishing operation of gill nets for croaker and trap nets for rock shell which is called the the other trap nets, and then measured the body length of croaker and blue shell caught by their fishing vessels. The results are as follows ; 1. The total number of permission for coastal fishing are 12,944 cases, but the number of operation for coastal fishing are 7,558 cases in the coastal area of Yellow Sea. Among the total number of permission, the gill nets fishing are 5,154 cases with 39.8% but even so the number of operation are 3,724 cases, the trap nets fishing are 1,025 cases with 7.6% but even so the number of operation are 662 cases. On the fishing ratio, the gill nets and trap nets fishing are comparatively higher than the other fishing with 72.3% and 64.6%, respectively. 2. The main fishing period of gill nets for croaker is from the middle of July to early of September, and the main fishing grounds are sandymud bottom of 15-50m in depth around the islands of southern parts of western coastal area, and the fishing operation carry out 1∼2 times per day in flood tide and nets hauling conduct in 1∼2 hours after drifting with current. 3. The distribution range of body length of 139 croakers, which are caught in the gill nets, are 43.0∼120.0㎝ and the mode is 85.0㎝. 4. The main fishing period of trap nets for rock shell which is called the other trap nets is all the year round except the catching period of blue crab from early of September to the middle of October, and the main fishing ground are the sandymud bottom of 10∼20m in depth, and nets hauling conduct in next day after nets casting. 5. The distribution range of maximum carapace of 5,372 rock shells are 4.5∼8.5㎝ and the mode is 7.5㎝.

One of the criteria provided by the law to designate the Impact Fee Zone requires that the increase rate of the development permit should exceed that of the entire locality by more than twenty percent. Since the permits are issued to scattered parcels on the individual basis, however, it renders significant difficulties in accurately figuring out the finite local areas that exceed such legal criteria. This study, in this context, tries to join the development permit time-series data with the Korea Land Information System (KLIS) so that, with the aid of the landform layer and existing infrastructure layer, it could pinpoint the local area where the development activities are concentrating. Taking a sector in Yangpyong County as the case, the study practically demonstrates as to how the designation process is geospatially processed.

One of the criteria provided by the law to spatially determine the zones to levy the so-called development impact fee requires that the increase rate of the development permit should exceed that of the entire locality by more than 20 percent. Since the permits are issued to scattered parcels, however, it renders significant difficulties in accurately figuring out the finite local areas that exceed such legal criteria. This study, in this context, tries to join the development permit time-series data with the Korea Land Information System (KLIS) so that, with the aid of the landform layer and existing infrastructure layer, it could pinpoint the local area where the development activities are concentrating. Taking a sector in Yangpyong County as the case, the study demonstrates the methods to designate the zone by processing the permit information data.

In September, 2008, the government has amended the National Territory Planning Act" by adding criteria to designate the Impact Fee Zone on the basis of the increase rate of the development permit. Since the permits are issued to scattered parcels on the individual basis, however, it renders significant difficulties in accurately figuring out the finite local areas that exceed such legal criteria. This study, in this context, tries to join the development permit time-series data with the Korea Land Information System (KLIS) so that, with the aid of the landform layer and existing infrastructure layer, it could pinpoint the local area where the development activities are concentrating.

코로나19의 영향으로 최근 국내에서는 야외 야영장에서의 캠핑을 즐기는 사람들이 크게 증가하였으며, 이와 더불어 최근 야외 캠핑장의 화재 발생 건수가 크게 증가하는 추세에 있다. 캠핑장과 같은 야영장 영업허가를 얻기 위해서는 「관광진흥법 시행규칙」에 따라 소화기를 적정하게 확보 배치해야만 하는 허가 기준이 존재하며, 그 기준은 야영장 2개소 또는 100미터제곱마다 소화기 1개 이상 설치하도록 되어있다. 그럼에도 화재가 많이 발생하는 이유로는 소화기가 설치되어있다는 것에 대한 인지 부족이라 생각된다. 한편, 야외에 설치되는 소화기는 상대적으로 그 유지관리가 어려울 것이라 판단된다. 따라서 본 프로젝트에서는 무게가 무겁지 않아 아이들과 노인들도 쉽게 사용할 수 있는 휴대용 소화기구, 사용 시 환경의 오염이 적은 소화기구, 여행객의 감성을 한층 증가시켜줄 수 있는 소화기구, 유지관리가 편리한 소화기구의 개발을 목적으로 하였다.
