In this study, the author analyzed satisfaction with Samhak Island Park among park users with an aim to provide basic data essential to be applied in the planning and design phases in a way that enhances their satisfaction in the process of setting up the reorganization plan of this park entailing both the history and culture of Mokpo City. As a first step, the author first examined the characteristics of this park in terms of history and closely looked into the organization and features of park facilities. Secondly, the direction of space improvement plans was proposed based on the findings of the survey on satisfaction among residents and visitors at Samhak Island Park. To summarize the ways to improve park space considering satisfaction among park users, the current park Zone(A) at Mokpo landfill should be designed to address problems in terms of visiting, uphold the local identity, and introduce popular and trendy items, while maintaining the principle of making the best use of the present park facilities. Second, Zone(B) should be designed in a way that takes greater advantages of the restored Samhak Island. Third, Zone(C) representing an entrance requires tasks such as promotional activities to make public its location, landmark installments such as a movable bridge, and improved path guidance. Fourth, Zone(D) by the ocean of this island at the inner harbor should be designed to reflect its outstanding view point in the way that the users are allowed to have easier access from land as well as from the inner harbor as part of its view-attracting plan. The findings revealed that when it comes to building new parks using existing islands, strategies and plans to maintain its identity as an island while upholding its culture and feeling are needed rather than proposing its role as an ordinary neighborhood park to boost facility use and user satisfaction. This way is expected to successfully ensure sustainability related to parks using existing islands.

신순호(Shin Soon Ho),박성현(Park Sung Hyun) 한국도시행정학회 2011 도시 행정 학보 Vol.24 No.1

The purpose of this study is to suggest a preliminary data based upon implications from the analysis of Japan’ s Play Park that how we could introduce Play Park in the urban environment. With this in mind, We have looked at the concept of Play Park, the history of Play Park, and the role of Play Park. After that, We have examined “Hanegi Play Park”, which is known for the most advanced model in Japan, based on the following analytical frameworks. First of all, We identified geographic characteristics (location, area, space, facilities, and tools), and then looked into utilization(number of users, age of users, and contents of play), operating structure(operating system and solidarity), and operating contents and method(finance, safety, program, and insurance). In order to enhance the accuracy of research, We have used the different way of research according to its characteristics such as geographic characteristics with observation and utilization, operating structure, and operating contents and method with interview. After analyses, We have found out that a few thing were shall be considered before it introduced Play Park in urban environment. First, Play Park did not require special components such as condition of site and man-made structures, therefore We suggested that we should consider trying the existing park that hardly uses or becomes obsolete on a trial basis. Second, We suggested that we need to take account of operating solidarity in order to make the best use of Play Park. In other words, it shall be an organic cooperation system that local government limits their role to provide only place and finance, while residents could take charge of Play Park operation and all other matters as a “trust”way. Last but not least, it should be discussed how to raise funds. In case of “Hanegi Play Park”, it consists of two parts with ratio of 3:1; consignment fee from local government and earnings from own business. We, however, need to discuss whether this ratio is reasonable or not. It is more desirable to raise funds through own business as much as possible rather than local government financial support.

Park Sang‐Hyun,Ha Young‐Ho,Kim Dong Eon,Kim Chang‐Jun,Choi Moon Bo 한국곤충학회 2021 Entomological Research Vol.51 No.3

Argentine ants (Linepithema humile) are one of the world’s most invasive species and were first reported in South Korea, near Busan Port in 2019. The distribution of their initial spread was investigated here from April to July 2020. In the invasion area, numerous nests and individuals were identified, indicating that they had settled and successfully invaded the habitat. To track the invasion of the Argentine ants we conducted haplotype analysis using COI, COII, and Cytb sequences of their mitochondrial DNA. The invasive ants had the same mitochondrial haplotype (H3) as Argentine ants from America (Chile, Ecuador, Bermuda) and East Asia (Japan). When comparing the import trade volumes at Busan port with the Argentine ant haplotypes from other countries, it was determined that the invasive ants may have originated from the United States or Japan. Numerous ecological and economic impacts due to their invasion and spread in other countries has previously been reported. Therefore, prompt control measures for the Argentine ants found at Busan port, at this relatively early stage of settlement, is required.

Two types of polyimide/silica composite films were prepared using sol-gel method through hydrolysis and polycondensation of tetraethoxsilane(TEOS) with the polyamic acid(PAA) and end-capped PAA solution. Sample were characterized by the means of differential thermogravimetry, X-ray diffractometry, scanning electron microscopy, universal test, impedance analyzer, chemical resistance test, etc. All of the PAA/silanol solutions heat-treated at 300℃ for 6h were transformed to polyimide/silica composites. It has been demonstrated that the properties of polyimide/silica composites were affected by the amount of silica addition and the bond type existed between polyimide and silica.

It was carried out to measure the species diversity and community structure of ants at the Yongdu Hill Park in Busan Metropolitan City, that was a part of a survey investigating urban insects. As a result, found were the ants of 10 species belonging to 3 subfamilies and 9 genera. The species divesity index(H') of Simpson was 0.48 and species abundancy index(R') of Shanon-Weaver 3.07. The most dominant species were Lasius niger (Linn?) and Myrmica kotokui Forel which were 0.24 and 0.17 in donhinance index. Overall eveness was 0.5, which may be higher forming moderately stable community. However, the rest species including Crematogaster matsumurai Forel, Paratrechina sp. 1, Brachyponera chinensis (Emery) and Monomorium chinense Santschi were found as small colonies at the limited sites measuring their eveness index of 0.001. To describe their inhabiting microhabitats of the abundant species, Lasius niger was found largely along the flower bed of the park, while M. kotokui along the sides of footpaths. The result may support that the distribution and densities may be diverse upto environmental characters, and that different composition of ant species may reflect the urbanized level of city.

( Hyun-su Hwang ),( Jae-kang Lee ),( Tae-kyung Eom ),( Ho-kyoung Bae ),( Dong-ho Lee ),( Jong-hwan Lim ),( Sung-cheol Jung ),( Chan-ryul Park ),( Shin-jae Rhim ) 한국산림과학회 2020 한국산림과학회지 Vol.109 No.1

In this study, the elevational distribution of breeding birds in Seoraksan National Park, Korea was investigated. Forty-six species of birds were documented from line transect surveys taken from Seorakdong at 230 m above sea level (a.s.l.) to the Daechungbong summit at 1708 m asl. Birdspecies richness and diversity were highest in Seorakdong and lowest at the Daechungbong summit. As elevation increased, bird species richness and diversity decreased, with a humped-shape trend being observed between 700 m and 1200 m a.s.l. Stepwise analyses revealed that breeding bird species diversity indices were significantly negatively correlated with elevation (r² = 0.327, P < 0.001) and positively correlated with vegetational coverage (r² = 0.324, P = 0.046). Higher elevations supported fewer birds than low and intermediate elevations. Projections at the local scale, including data on behavior and habitat use by birds, will be necessary for optimal conservation and management of the bird communities in Seoraksan National Park.

The impact of blowflies on pig cadaver decomposition on Yeongdo Island, Busan, South Korea

Park Sang‐Hyun,Baek Seung‐Ho,Moon Tae‐Young 한국곤충학회 2021 Entomological Research Vol.51 No.11

The decomposition process is an important factor in forensics, and flies play a crucial role in the decomposition of animals and humans. However, there remains limited information on the effect of flies that attend death scenes. This study assesses the effect of the presence or absence of blowflies on the rate and process of cadaver decomposition in the spring, summer, and autumn from 2016 to 2020 on Yeongdo Island, Busan, South Korea. Nine blowfly species belonging to four genera in two subfamilies were sampled. The blowflies that approached the cadavers differed between seasons, but Chrysomya pinguis (Walker) was the dominant species regardless of the season. Blowfly presence on cadavers significantly affected the duration of the decomposition stage and the pattern of weight loss in nearly all scenarios. With the presence of blowflies, the decomposition rate was four times faster in spring, three times faster in summer, and nine times faster in autumn. These results show that the presence or absence of blowflies is an essential factor in the decomposition process of cadavers. Therefore, it should be taken into account when estimating postmortem intervals in medicolegal forensic entomology.

Consistency of seasonal patterns of insect succession on pig cadavers at Yeongdo Island in Busan, Korea

Park Sang‐Hyun,Moon Tae‐Young 한국곤충학회 2021 Entomological Research Vol.51 No.1

Cadaver insects cause dead bodies to break down in ecological processes. Still, the knowledge has been accumulated slowly about the structure and role of the insect assemblages attending to death scenes. This study analysed the successional patterns of insects on pig cadavers in the spring, summer, and autumn from 2016 to 2019 at Yeongdo Island, Busan, South Korea. A sum of 71 insect species belonging to four orders and 21 families were sampled. Predominant insects were largely Diptera and Coleoptera. The majority of the flies were the calliphorids as Chrysomya pinguis (Walker) and Lucilia porphyrina (Walker). The most common beetles were Creophilus maxillosus (L.), Omosita japonica (Reitter), and Staphylinidae sp. regardless of seasons. Occurrence matrices were made from the successional patterns of insect species during 42 sampling intervals in the spring, 38 sampling intervals in the summer, and 26 sampling intervals in the autumn. Permutation analyses of the occurrence matrices showed that the patterns of succession were similar between spring 2016 and 2017 (P = 0.019), between summer 2016 and 2017 (P = 0.003), and between autumn 2016 and 2019 (P = 0.002). The result shows that there are clear patterns in succession between seasons, and provides the reference data to presume the death time, at least in the southeast part of South Korea.

Forensic implication of cadaveric behaviors of the Japanese pavement ant (Tetramorium tsushimae Emery) attending to rabbit cadavers

Park Sang‐Hyun,Moon Tae‐Young 한국곤충학회 2020 Entomological Research Vol.50 No.4

It is noticed by some researchers that ants may cause some forensic confusion in understanding death scenes. In the aspect of relationship between the ant-animal decomposition, we observed the behavior of ants congregating on dead animals. Amongst various species of ants visiting dead rabbits, Tetramorium tsushimae Emery was noticeable in producing scratched scars, mounds, and nests around dead rabbits and covering them with soils. The behaviors are likely to interfere or to disturb the usual process of decomposition succession lead by maggots. We discussed that a series of cadaveric behaviors of T. tsushimae may be used as a potential forensic hint not to misunderstand death scenes disturbed by the species.
