This study suggests the invigoration strategies of commercial and business functions for regeneration of old inner city as city center by examining Dangjin County which is a typical example of the local small-and-medium city where old inner city had declined as the city grew. I conducted a conjoint analysis in terms of important introduction functions and city regeneration directions for the invigoration. The results upon this are as follows. First, low-density of commercial and business places and the utilization of historical and cultural resources instead of the high-density mixed-use development should be considered. Second, It is important to promote regional specialized business and facilities rather than to attract new industry(high-tech industry) for activating local economy. Third, specific and practical countermeasures for resettlement of low-incomes and for maintenance of existing business zone should be established. Fourth, in terms of the maintenance and management, regulation on illegal commercial transactions, improvement of public spaces, and securement of user safety should be considered. Fifth, in terms of consolidation of functions, easier accessibility using public transportations, advertising and promotion of the city, and holding a number of events should be contemplated. Sixth, supporting for business activities and for establishing guides for design of old inner city should be needed. Seventh, public institutions should play a role as a bridge between local residences and experts for balanced regional development.

This study identified characteristics of households in Seo Geumsa based on factors related to how well each household understood and agreed or disagreed with the Newtown project and the resettlement process that is required to establish the renewal promotion plan. To this end, the authors applied the unit of spatial analysis developed by Tong, segmented the land intended for large-scale development, and then developed a method for analyzing and comparing the segmented lands by certain characteristics. The results of the survey were analyzed in three stages: the characteristics of districts; the relationships between agreement and disagreement factors and differences among segmented districts. And, to assess districts with features that differed from the overall features of households in renewal districts, the authors developed a two-way stage division plan and conducted a cluster analysis. The authors analyzed districts with individual characteristics based on the household features developed by Tong, and then analyzed the features of household distribution in these districts along with spatial location.

Lychnis wilfordii (Regel) Maxim. is one of the wetland specialists mainly distributed in peatlands at high latitudes. In Korea, it is isolated in two regions. This study investigated habitats, growth traits, and self-compatibility of L. wilfordii and assessed the internal dynamics of its population persistence. Its population has remained stable in the Yongneup Wetland Protected Area (YWPA). There was a clear difference in vegetation environment between YWPA and the distribution area in Daegwallyeong (DWL), Pyeongchang-gun. It has self-compatibility while pollinators facilitate its seed production. It produces a large number of hibernacles and bears the maximum number of branches and fruits in soil with rich organic contents. However, it grows and bears fruits even under the condition of low organic contents. In YWPA, L. wilfordii is not distributed in high moor but widely distributed in low moor where tussocks by Carex thunbergii var. appendiculata are developed. It is mainly distributed on the top of tussocks also. Therefore, it is judged that the formation, growth, and extinction of tussocks by C. thunbergii var. appendiculata is closely related to the establishment, growth, and extinction of plants distributed in this space. It is assessed that the current YWPA has well-developed tussocks in which L. wilfordii is widely distributed, and extinction and re-establishment progress well. Accordingly, the L. wilfordii population is expected to be sustainable in the long term given if its current ecological process is maintained well.

The aim of this study is to analyze the evaluations and determinants on residential resettlements in accordance with urban regeneration by 7,396 samples from 19 housing redevelopment districts in Busan. The major finding on determinants on residential resettlements in accordance with urban regeneration are as follows; A binary logit model for determinants on residential resettlements in accordance with urban regeneration are composed of owner's characteristics, land and building characteristics, housing complex characteristics, and location characteristics. The significant variables in relation to owner's characteristics are owner's age, owner's place of residence, the possession period against property and investment intention. As a result of logit model for residential resettlements, it shows that the variables in relation to land and building characteristics are the land classification, the use of building, the size of land or building, the permission of building and the appraisal price on land and building. This result means that actual customer's investment connects to resettlement after redevelopment project. The other side, the housing complex variables consist of the brand of construction company, the ratio of large size housing and floor are ratio shows that improvable conditions for housing value are important factor to induce residence's resettlement. The location variables show that Dongbusan has higher probability, the reverse Jungbusan has lower probability in residential resettlement likewise residential preference.

Evaluation of the extinction risk of endangered plants at international, national as well as at regional levels is essential to the implementation of plans for direct conservation activities. Reports indicate that 34 endangered plants are distributed in the middle eastern area of Korea. For each endangered plant, we investigated the sites, area of extents, population size, and factors that affect population extinction. We assessed risk factors based on 10 evaluation criteria including the results from the investigation and the life traits each endangered plant has. As a result of evaluating the risk factors, these 34 endangered plants are classified into 3 groups: the first category comprises 12 endangered plants that require active and urgent conservation of habitats due to multiple risk factors; the second group has 16 endangered plants that should be able to persist with the removal of a few direct risk factors; the third category has 6 endangered plants that can persist with minimal management due to comparatively large distributed area and numerous individuals. It was found that most major risk factors in the population of endangered plants are caused by disruption of habitats and population extinction due to the increase of human habitation in the concerned areas, development and illegal harvesting. Futhermore, ecological collapse from decreasing habitats and malfunctioning mechanism of extinction and regeneration due to the changes of vegetational environment can be the other causes. From the area of the present investigations, we selected 5 regions according to the number of species and the frequency of appearance and importance of conservation measures. Also, we suggested a conservation strategy according to the regional characteristics. We suggest that the method for evaluating extinction risk of endangered plants includes distributional data and life traits of species. In addition, we underscore the necessity for understanding population dynamics and ecological niche of the each target species.

As Chinese insurance market grows rapidly due to market reforms, China got recognition as second-largest insurance market in the world in 2016. However Korean insurance companies have had difficulties to grow in Chinese insurance market despite Chinese participation in the World Trade Organization (WTO) and the growth of chinese insurance market. The reason for the decline in Korean insurance companies is economic retaliation due to the deployment of THAAD in Korea. However, this is not a fundamental reason. The underlying cause of the effects of economic retaliation is the result of insufficient negotiations in Korea-China FTA services sector. In Service sector of Korea-China FTA, the level of concession between Korea and China differs greatly, when comparing China and South Korea's FTA. In addition, it has only been a few years since China collected the position of the WTO Doha Agenda, which currently deals with concessions on intellectual property rights and services. More important is that the Korea-China FTA service sector, as it stopped short of being protected by the most-favored-nation state treatment level when Korean insurance companies entered China. Further negotiations to supplement the weak points in the Korea-China FTA service sector were promised in December 2017, but international tensions over THAAD deployment made it impossible to hold such negotiations. However, due to changes in international affairs in 2018, the first additional negotiation was decided and held. This paper implicates strategies of further negotiation between Korea and China for service and investment chapter. Consequently, the aim of this paper suggests directions how to re-enter Chinese insurance market to Korean insurance companies.

The rear edge population is considered to have low genetic diversity and high risk of extinction according to a highly isolated distribution. However, the rear edge population is observed to have persisted for an extended period despite the low genetic diversity. As such, it is necessary to understand the ecological process involved in the persistence of the population. Viola mirabilis L. in Korea is considered the rear edge population from the perspective of the worldwide distribution. We surveyed the distribution range of V. mirabilis, which shows the isolated distribution in the central area of Korea, to find out the factors of its persistence. Next, we investigated and accessed the vegetational pattern of habitats, soil environment, phenology, self-compatibility, population structure, and extinction risk factors observed in the distribution area. V. mirabilis was distributed in the understory of the deciduous forest, planted forest of the deciduous conifer and deciduous broad-leaved trees, shrubland, and grassland in the limestone area. We also observed the re-establishment of seedlings in the population, and most of them showed a stable population structure. For chasmogamous flowers, the visit by pollinators has a significantly positive relationship with the production of fruits. However, we found that the production of the cleistogamous flowers was more numerous in all studied populations and that only the cleistogamous flowers were produced despite a more substantial plant size in some populations. The plant size was more related to the production of the cleistogamous flowers than that of the chasmogamous flowers. Accordingly, the cleistogamous flowers significantly contributed to seedling recruitment in the population. We found that the production of the chasmogamous flowers and the cleistogamous flowers did not have a correlation with the factors of the soil analysis except for phosphoric acid. V. mirabilis showed the self-incompatibility characteristics most likely due to the production capability of the cleistogamous flowers. Potential extinction risk factors observed in the distribution area was included the development of limestone mine, the expansion of agricultural fields, and the construction of houses. Although V. mirabilis showed an isolated distribution in the limestone area in the Korean peninsula, it showed a diverse distribution in a wide habitat environment ranging from the grassland to the understory of the trees with relatively low canopy closure rate. Moreover, we concluded that the persistence of the population was possible if we can maintain the current state of multiple populations and stable population structure.

Following the adoption of the global plant conservation strategies at the Conference of the Parties for Biodiversity Conservation, diligent actions to achieve each targets are actively carried out. In particular, the need for ecological conservation research to achieve targets 2 and 7 of GSPC-2020 has increased. The priority taxa to accomplish the objectives of GSPC-2020 are rare and endemic plants. In particular, endemic plants with limited distribution in specific regions are evaluated to face a high risk of extinction. To address the necessity to preserve endemic plants, we investigated the distribution of Prunus choreiana H. T. Im, a Korean endemic plant. After that, we examined the vegetational environment of the habitat of P. choreiana and evaluated its population structure. The productivity of its fruits and the effects of pollinators on fruit production were evaluated as well. The fruiting ratio was calculated based on the number of flowers produced. Lastly, we observed the annual growth characteristics of P. choreiana. The habitats of P. choreiana did not show a specific type of vegetation. All of them were located in a limestone area of Gangwon-do in the central Korean Peninsula and occupied a site where the coverage of the tree layer and the sub-tree layer was not high or did not exist. The population structure of P. choreiana contained a high proportion of mature plants capable of producing fruits and a low proportion of seedlings and Juvenile plants. We found that the production of fruits required pollinators and was affected by the performance of each plant. Although P. choreiana produces many flowers, only a maximum of 20% and only 2-6% on average bear fruits. These flowering characteristics may be due to pollinators' low abundance and activity during the flowering season (between mid-March and early April), suggesting that many flowers are needed to attract more pollinators. We rarely observed the re-establishment of seedlings in the population of P. choreiana. Despite that, we predict the population to persist owing to its long lifespan and periodic production of numerous fruits. However, if the tree layer and sub-tree layer in competing status with P. choreiana increase their crown density, they are expected to inhibit the growth of P. choreiana and affect the risk of its extinction. Therefore, the current changes in the vegetational environment of the habitats are expected to decrease the number and extent of P. choreiana in the long term. The results of this study may serve as primary and important data necessary for the achievement of GSPC-2020 objectives.

Youngsan is generally known as Pansori Danga(短歌). However, the contents of 'Yeongsan' in 『Songnamjabji』 are different. In 『Songnamjabji』, Cho Jaesam explained the contents related to 'Youngsan' using three kinds of poems: Shin Kwangsoo's poem, Baegho Imje's poem, Kim Myeongwon's poem. First, 'Ujo Youngsan' appears in Shin Kwangsoo's poem. Shin Kwangsoo wrote the (1750) when Yoo Jinhan's 『Manhwajib(晩華集)』(1754) was published. It is difficult to see the 'Ujo Youngsan', which appears in Shin Kwangsoo's poem written in a time when Pansori was not widely known, as the Pansori Danga. Second, Jo Jaesam called the music in Baegho Imje's poem 'Youngsan Dodeueum'. In 'Youngsan Dodeueum', flute and 'Dodeuli rhythm' were used. This fact is connected with , an instrumental music. , also a Buddhist term, continued to be used in the palace as well as among the people. Third, Cho Jaesam introduced Kim Myeongwon's poem in 'Yeongsan' part and called it 'Taryeong.' At that time, the term 'Taryeong' referred to both Pansori and Jeongga(正歌). Later, in the 19th century, 'Youngsan' was recorded as a term for the Danga to loosen the neck before Pansori began in earnest. In other words, the early 'Yeongsan' recorded in 『Songnamjabji』 was a Buddhist term, referring to the music of the upper class Seonbi, such as , Gasa(歌詞) and Sijo(時調). In 1855, when 『Songnamjabji』 was written, 'Youngsan' was used as a term used to refer to both Changbu-Music and Gagaek(歌客)-Music, mixed with the term 'Taryeong'. And as Pansori became popular, the term 'Taryeong' came to be called 'Pansori' and 'Youngsan' was used to refer to Pansori Danga. Therefore, all the records of 'Youngsan' should not be interpreted as Pansori Danga. This situation is closely related to religious and social change. The policy of worshipping Confucianism and suppressing Buddhism rejected the term 'Youngsan' which had a Buddhist meaning. In the middle of Joseon Dynasty, when Buddhism was suppressed, 'Youngsan' and 'Taryeong' were mixed. As Buddhism regrown in the late Joseon Dynasty, with the advent of Pansori, the term 'Youngsan' seems to be newly resettled in the sense of Danga. Pansori appeared in the 19th century and 'Yeongsan' was used as a Danga. And the reason should be regarded as this social and religious change.
