A rapid decrease of total fertility rate to 1.08 in 2005 prompted the Korean government to plan and implement a '5-year plan for ageing society and population policy' starting from 2006. The 1st and 2nd 5-year plans had not shown any discernible impact on the fertility and the 3rd 5-year plan was launched in 2016. However, the fertility rate is going down further. The author reviewed the contents and assessment reports of the fertility promotion plan to suggest ideas for complementing the shortcomings of it. Author defined the major determinants of marriage and child birth as philosophy, politics, sense of value, social norm, culture, healthcare, and education. The plan was examined in view of these determinants. Transformation of Korea from an agricultural society to an industrialized society in a short period of time had brought about changes in most of the determinants of marriage and child birth; in particular philosophy and sense of value. These aspects were not put into consideration in the plan. Author suggested to launch a social education program for the general public to establish a sound philosophy of life, reform the sense of value on family, child birth and education, and cultivate the skill to draw a consensus through discussions on the social issues. A special program to promote marriage of women at the optimum age for child birth was proposed. The government should implement well balanced policy for economic development and labor. Multidisciplinary approach was recommended for these tasks.

The Master Plan of Natural Environment Conservation in Korea by Ministry of Environment has been carried out since 1986. The 2nd 10-year survey started in 1997, and there are three major parts in the Master Plan : First, the basic natural environment survey, second, sites in special features of ecological characteristics such as uninhabitable islands, wetlands, etc, and third, biological species featuring status of habitat, and population dynamics. However the information in the Master Plan is very fragmented and collected data are not so abundant due to insufficient man-power and unsynchronized survey time/season. In this regard this paper examined the similar National Biological Survey in USA and compared the differences with the Master Plan in Korea. The Master Plan in Korea should separate the management zone based on hydrological characteristics, and in each zone we should set a management goal in the long term basis. Secondly the species list is not so meaningful that we must concentrate more on research activities. In each taxonomical group we set up hypotheses and research goals. Thirdly local residents and communities should be involved in research so that enhanced biological diversity should benefit people in areas. Lastly legislation and laws should be reexamined and rectified to provide information to the managers that deals with natural resources, expecially when conflicting with economic matters.

The purpose of this study is to explore changing attitudes towards old urban environments, represented in the comprehensive plans of Seoul, from the first 1966 plan through the most recent one of 2014. The results of analyzing all 6 Seoul urban comprehensive plans are as follows. The contents for considerations and actual planning actions for old urban environments were presented from the third comprehensive plan of 1990. The term 'historical heritage' was first applied in the urban park planning of the 1996 plan. In the 4th comprehensive plan of 1997, it began to regard historical landscapes as 'precious heritages' to make plans for using historical heritages in parts of landscape, education, and tourism. The scope of 'historical heritage' in the comprehensive plans has been expanded. This tendency continued to expand in the 5th plan of 2006, and again in the 6th plan of 2014. At the same time, in pursuing the identity of Seoul, 'historical heritage' in old urban environment came to be materialized further as planning objects.

The recent surge in the production and handling of hazardous materials in Korea necessitates developing and implementing robust emergency response plans. These plans are crucial in safeguarding the well-being of workers and residents in the event of an incident. The consequence analysis methodology outlined in the KOSHA guidelines provides a foundation for designing emergency response plans in the event of chemical accidents. However, the consequence analysis is evaluated based on assumed accident cases or worst-case scenarios. Consequently, the emergency response plan based on the consequence analysis may overestimate the damage area, complicating rescue efforts and unnecessarily increasing costs. More information and parameters become available after an accident, enabling more accurate consequence analysis. This implies that the results of consequence analysis based on this detailed information provide more realistic results than those based on assumed accidents. This study attempts to optimize the resource allocation and cost-effectiveness of emergency response plans for chemical accidents. Existing procedures and manuals are revised to elucidate the proposed model and conduct real-time consequence analysis. The existing emergency response plan is compared to verify the proposed model's efficacy. The obtained results indicate that the proposed model can exhibit better performance.

The long term plan for apartment housing has a important role to make a decision making whether a repair work should be done or not. But, items for repair works are so various that field workers could not understand the context or plan the repair cost and time. These difficulties are drawn from the number of repair items, duplicated application and meaning, new material application and technology time-gap. Therefore, it needs to change or coordinate the repair items to improve the repair condition, reflecting the current material level or repair technologies. In this paper, it aimed at coordination of the repair items through the repair recording sheet which was surveyed in 22 metropolitan areas of Seoul, conducted between 2011 and 2014. The surveyed data are classified into six categories such as building exterior, building interior and so on, according to long term repair plan and the number of data are 1,918. It analyzed the appearing word for repair-concerned and compared the existing items of the long term plan. Items of building exterior are proposed as roof, exterior wall and painting. Building interior has a little meaning to propose the repair items. The water supply facilities are proper to keep the existing repair items. Items of the outdoor facilities could not need a sign board, drainage root and PVC sheath. Through this study, we can coordinate the repair items in apartment and provide the repair item and cost level.

For the first time basic settlement area development plan was established in 2010, in order to promote cooperative coexisting development among regions, as time that regional competitiveness determines national competitiveness started. Basic settlement area development plan is composed of 7 sectors and 24 general subsidy projects. It was judged that experience and tourism business as the center is required to be analyzed, which may have effect on activation of farm village, fishing village and mountain village, and inflow of city people, in agriculture, forestry and fishery sector in order that added value of agriculture and fishery is increased, and tangible and intangible resources are applied, and pure agriculture, forestry and fishery is developed. And currently farm village, mountain village and fishing village of our country faces desperate crisis situation that they cannot help groping for substitutive to create new revenue model, and agriculture and fishery of primary industry has limit of increasing income of farmer and fisherman. Agriculture, forestry and fishery experience and tourism business was classified by types, and then standard of 12 categories and 48 sections was prepared, for searching method to supplement and develop it. Trend of experience and tourism business was understood, and problem was found, and then it may be used as indicator material to carry out creative and differentiated business plan establishment and business operation, and may be opportunity to reject overlapped business among regions, and to promote balanced regional development.

Establishing a ship's passage plan is an essential step before it starts to sail. The research related to the automatic generation of ship passage plans is attracting attention because of the development of maritime autonomous surface ships. In coastal water navigation, the land, islands, and navigation rules need to be considered. From the path planning algorithm's perspective, a ship's passage planning is a global path-planning problem. Because conventional global path-planning methods such as Dijkstra and A^* are time-consuming owing to the processes such as environmental modeling, it is difficult to modify a ship's passage plan during a voyage. Therefore, the D^* algorithm was used to address these problems. The starting point was near Busan New Port, and the destination was Ulsan Port. The navigable area was designated based on a combination of the ship trajectory data and grid in the target area. The initial path plan generated using the D^* algorithm was analyzed with 33 waypoints and a total distance of 113.946 km. The final path plan was simplified using the Douglas-Peucker algorithm. It was analyzed with a total distance of 110.156 km and 10 waypoints. This is approximately 3.05% less than the total distance of the initial passage plan of the ship. This study demonstrated the feasibility of automatically generating a path plan in coastal navigation for maritime autonomous surface ships using the D^* algorithm. Using the shortest distance-based path planning algorithm, the ship's fuel consumption and sailing time can be minimized.

A planned access method on constantly-changing-community unit plan changes and develops based on the periodical situation and also plan theory. In this research, it is to present the link between the theory of complex city change and the plan factor of it, and to show how Korean residential complex plan has changed as time passed and how new concept of city plan came up and by applying new methods how can this affect our real world and the past plan. In the phase of analysis, it analyzed the flow of 'community unit plan' and its theory and investigated the factor of compositional space and built a analysis frame. The factors of community unit plan are space structure, size and shape of block, population, distribution of facilities and movement system. It chose the place that can represent the flow of community unit plan trand and that indicates the obvious development leading to Jamsil (1975), Gwa Chun (1980), Mok Dong (1983), Sang Ge (1985), Ilsan (1989), Dong tan (2001) and Eun Jung (2003) total of 7 places. And to compare a similar size of the city, it selected a small community unit. Based on the result of theoretical study and prior research, it can be said that the space composition style has change from a whole complete complex area to a linked-cross over community unit and the access of urban level was on set. Also, a pedestrian walking area was secured and the dense of building structure and pleasant environment wanting need was in balance. For facility plans, the usage of facility and functional change brought change of type, size and disposition. The walking area for pedestrian became a huge matter. Therefore, market, education, public facilities and green system collaborated to co-build a whole community unit and activated the walking environment. Also, public transportation, environment friendly city organization was built.
