Lately construction industry tends to prefer remodeling of existing buildings rather than new construction or reconstruction of buildings due to strengthening of several restriction related to real estates along with prolonged depression. And also, remodeling of building costs less and creates less wastes compared to reconstruction and so it is more profitable in financial and environmental view. However remodeling is process of creating new environment with existing building. Therefor remodeling must follow the procedure realizing problem and fix the problem based on through investigation on existing building and users requirement must be faithfully reflected. Specially in case of apartment houses, since vagueness on ownership and management authority on common parts exists. Hereupon, in this study we are to present the procedure of analyzing apartment house remodeling method through user requirement by approaching to several considerable factors in user request side.

The purpose of this study was to confirm that the formation and influencing factors of ocean governance in Busan. Recently it has been observed that the concept of ocean governance increasingly popular in the field of maritime administration, as the concept helps us understand more comprehensively the new or emerging roles of the government and other stakeholders(private enterprise, citizen, etc) in a rapidly changing environments. Therefore, this study aims to investigate the status of ocean governance and draw alternatives in applying appropriate ocean governance structure of maritime administration in Busan. The result of this study shows that ocean governance level in Busan was not high in some factors such as participation, cooperation, collective decision making. This is caused by the lack of a ocean governance structure. Based on these significant research findings, theoretical and practical implications were discussed.

The sustainable reduction of the fisheries resource is keenly raised an urgent problem of the fisheries policy in Korea, China and Japan. Then, 3 country, Korea, Japan, China, have established various system for fisheries resource management. Among these systems, qualitative fishing regulations have been commonly established. For example, its have been enforced to the prohibited fishing region, fishing period, fish size, net size, specified fishing methods. Also, different fisheries resource management policies have occasionally enforced by each country. For example, the prohibition of free sale and free possession has been established in Korea and Japan, but not China. And, In Korea, It has been enforced uniquely to entry system far fishing license number ana sea farming project for coastal fishing grounds by national government. The entry system for fishing license number has been enforced in Japan too, not national government, but local government. Nevertheless these three countries have put good system for fisheries resource management above mentioned, real enforcement has been not operated well. For efficient management on same fisheries, next problem will have been solved. First, it has to be guaranteed to transparency on the fisheries management, which is considered the priority problem on the fishing regulation. For reason, although efficient system is established in each country, if feasibility of the system was not trusted, mutual effort like that is very difficult to gain desired results. Then, each country has to establish transparency on the fisheries statistics and administration. Second, it has to be adjusting on the criteria or level of fisheries resource management. Now Korea, Japan and China have different criteria or level of fisheries resource management, for, example, prohibited fish size and prohibited fishing net sine. To solve above problems, three countries need to deeply discuss together. Then fisheries resource co-management scheme should be established in same fishing ground.

And because it represents an identity of the country, it is an important records information resources that we must be inherited from generation to generation. Korea's intangible cultural heritage system has developed with the aim of preserving and transmission, but now it is necessary to take an creative approach as a resource as a resource for cultural diversity and utilization in an intangible cultural source. Therefore, it is important to maintain systematic management of intangible cultural heritage records information resources in order to continuously preserve, but it is also important to establish a basis for continuous use. The purpose of this study is to propose improvement plans for the archival information services of domestic intangible cultural heritage. We analyzed the status of the archival reference services of intangible cultural heritage institutions in consideration of the characteristics of intangible cultural assets. In-depth interviews were conducted with the responsible person to collect opinions and requirements during the service. We suggested the improvement plans through drawing out implication on problems and direction of archival information services for intangible cultural heritage.

From now on, the aged apartment or house is expected to increase rapidly. So, we have to build a process of remodeling and develop the new technique. Demolition work is needed for systematic plan and management. However, contractors of the remodeling project established a rough plan and did not consider recycling wastes, safety of workers and structural stability of building. Therefore, we need a step to develop a assessment system, verify and make specified. This paper evaluated how much improve on construction speed, work efficiency, intensity of work and influence with another process comparing the existing method with the new demolition method. The qualitative and quantitative assessment system are developed with these output. The case study was carried out experimental group and control group, based on developed assessment system, which have the same condition. The existing method was made up of 3 steps- 1)Demolish windows, doors and iron goods, 2)Demolish indoor and outdoor walls, 3)Drop the waste. The new demolition method was made up of 5 steps- 1)Demolish windows, doors and iron goods, 2)Demolish the ceiling and wall's finishing materials, 3)Demolish the floor's finishing materials, 4)Demolish indoor and outdoor walls, 5)Drop the waste. Work time, idle time, the character of a work unit are analyzed by mock-up test. This study's output is expected to establish a systematic process of new demolition method and based on the maximizing waste recycling work in our construction industry.

The PC structure based on the OSC (Off-Site Construction) is mentioned as a representative method of innovation in the construction industry that converts the existing construction environment from site-centered to factory production-transportation-site assembly. However, recent research on PC method has focused on improving the functions of subsidiary materials and improving the production system to increase productivity and institutional / policy R&D that can be universally applied to the life-cycle stage of ordering / design /construction is insufficient. In particular, the absence of standardized cost calculation standards makes it difficult to calculate and verify of objectified appropriate construction cost. So which is an obstacle to the activation of the PC method. In this study, the standards for construction costs of domestic and foreign PC method were surveyed and similar Construction Standard Production Rates were analyzed to confirm the product structure suitable for PC method. Subsequently, the construction procedures and input resources for each PC subsidiary materials were identified through on-site surveys to derive component for subsidiary materials, and the factors of change in the product according to the construction characteristics(height, weight of subsidiary material) were verified. As a result the standard product calculation system suitable for the site installation of the PC method for apartment was presented.

Although international construction market gradually takes a important position among the export industries, the previous studies about international construction entry strategy have just focussed on trend investigation or suggestion for revitalization. Moreover, in order to prepare the market uncertainty such as world financial crisis and to plan the long term strategy, specific strategy studies based on corporate level are required. Therefore, this study estimates the nine strategic index and four financial index of 31 companies that performed 1920 international projects from 1993 to 2007 and evaluate the performance as three periods by multi-regression analysis. Also, this study analyze dynamic correlation between these index and the performance considering times. this study verifies that market diversification, product diversification, localization and decrease of debt to asset ratio make a good effect on the international order as long term strategy and shows that collaborated entry with domestic corporations, alliance entry with host country's company, alliance entry with third country's company, portion of labor cost and portion of management expense differently make a influence on the performance as times. these results will be helpful for the construction companies to plan the international entry strategy reasonably and specifically.

1953년 7월 27일 정전협정 이후 한반도를 가로지르는 DMZ (Demilitarized zone: 비무장지대)가 설정되었다. DMZ에 출입은 군사정전위원회의 허가가 있어야 가능하기에 군사시설 및 군작전지역을 포함하여 DMZ 및 민간인통제선 이북은 민간인 접근의 제한으로, 단절된 공간으로 변모하였다. DMZ는 우리나라의 대표적인 동고서저의 지형 및 다양한 생태환경을 두루 갖추고 있어 중요한 생태적 요충지로 평가받고 있다. 산림지역은 민간인통제지역까지 합치면 40여개의 산지가 분포하고 있으며, 하천은 크게 15개의 크고 작은 하천이 위치하고 있다. 남방한계선 수계를 따라 일부지역들은 하천 배후습지, 묵논습지 등 습원형태로도 많이 발견되고 있다. 이런 습원지역들은 대부분 미확인 지뢰지대로 접근이 제한적인 만큼 지난 세월의 흔적들을 고스란히 담고 있다. 1965년 한국자연보존연구회는 30여명의 국내학자를 동원하여 서울에서 가까운 DMZ 인접지역에 대한 예비적인 학술조사를 실시하였으며, 이를 계기로 1966년 10월부터 1968년 9월까지 2년간에 걸쳐 한국자연보존위원회 34명의 국내학자와 미국 스미소니언연구소(Smithsonian Institution) H. K. Buechner 박사를 대표로 5명의 국외학자가 공동으로 종합적인 학술조사를 수행하였다. 이는 DMZ 연구의 시작을 알렸으며, 이후 남북관계나 시대여건에 맞추어 간헐적으로 다양한 조사 및 연구들이 이어져오고 있다. 2015년부터 2018년까지 DMZ 철책주변 현장조사를 통해 확인된 식물현황은 964분류군이다. 군시설로 인해 식물서식환경이 제한적인 상황이지만 척박한 환경에 적응하고 있는 식물은 다양하다. DMZ와 맞닿아 있는 7개 지역에 대한 식물현황은 철원 638분류군, 연천 631분류군, 양구 525분류군 순으로 나타났다. 대부분 중동부 지역에 높은 식물종수가 나타났으며, 서부와 동부의 식물들이 고르게 나타나는 결과로 보인다. 큰잎쓴풀, 봉래꼬리풀 등 희귀식물도 있는 반면, 잠재적으로 생태계에 영향을 줄 수 있는 침입외래식물도 다수 포함되어 있어서, 지속적인 모니터링 및 관리가 필요하다. 그 중에서도 양구지역에 새롭게 발견된 Macleaya cordata (Willd.) R.Br.(양귀비과)는 독성이 포함된 식물이며, 인제에서 2014년에 발견된 미역취아재비는 DMZ일원에 제한적으로 분포하는 종이였으나 현재 연천에서 발견되는 등 확산에 대한 관리방안이 필요하다.
