본 연구에서는 역사와 문화를 품고 있는 목포 삼학도공원의 재정비계획 수립과정에서 이용만족도를 높이기 위한 계획 및 설계에 필요한 기초자료를 제공하고자, 공원 이용자들을 대상으로 만족도 분석을 진행하였다. 구체적으로 먼저, 역사적인 측면에서 삼학도공원의 특징을 살펴본 후, 공원시설의 구성과 운용실태에 대해 살펴보았다. 다음으로 삼학도공원의 이용과 만족도 조사를 시민과 관광객을 대상으로 실시한 결과로는 첫째, 삼학도공원은 주말을 이용해서 가족 및 친구와 함께 여가를 즐기기 위한 공간으로서 근린공원의 특징을 보이고 있는데, 이는 시민들이 삼학도공원을 근린공원의 이미지로 인식하는 것과 맥락을 같이 하고 있다. 둘째, 삼학도공원을 찾는 관광객들은 전남지역에 거주하는 사람들이 많았고, 연령층은 시민과 비슷하게 40대와 50대가 가장 높은 것으로 나타났고, 이들은 가족과 함께 관광목적으로 방문한 것으로 나타났다. 셋째, 시민과 관광객 모두 삼학도공원의 이용 및 시설에 대해서는 대체로 만족하는 것으로 나타났으며, 시민은 그 이유로 편안한 쉼터와 좋은 자연환경이라고 응답하였다. 넷째, 시민과 관광객 모두 삼학도공원 이용 시 관리실, 화장실, 매점 등 안내 및 편의시설의 부족하다는 문제점을 제기하고 있으며, 삼학도에 새롭게 만들어졌으면 하는 시설과 사업에 대해시민과 관광객들은 섬의 정체성을 나타내기 위해 특색 없는 다리를 대신하여 육지와 삼학도를 이어주는 가동교 설치를 원하는 것으로 나타났다. 이용자간 만족도를 고려한 공원 공간개선 방향은 정리하면, 첫째 매립지의 기존 공원Zone(A)은 현재 공원시설을 최대한 활용함을 원칙으로 하고 이용측면에서 제기된 문제점을 개선하면서 지역 정체성을 살리고 최근의 트렌드에 맞는 새로운 아이템을 도입하는 방향으로 설계한다. 둘째, 삼학도 활용 Zone(B)은 복원된 삼학도를 적극적으로 활용하는 방향으로 설계한다. 셋째, 공원입구 Zone(C)는 공원의 위치 등 인지도 향상을 위한 안내 홍보 및 가동교 등 랜드마크 설치, 동선 유도책 등이 필요하다. 넷째, 목포내항 삼학도 해안 Zone(D)는 우수한 조망점이라는 특징을 적극 활용하고, 내륙과 내항측에서 접근이 용이한 동선 및 시선 유도계획 방향으로 설계한다. 본 연구의 결과를 통해 섬을 활용한 공원을 조성할 시 시설이용도 및 이용자 만족도를 높이 기 위해 일반적인 근린공원으로 그 역할을 제안하는 것보다는 해당 공원을 통해 지역의 문화와 정서를 담고 섬만의 정체성을 살리는 전략과 계획이 필요하며, 이러한 방식이 섬을 활용한 공원의 지속가능성을 보장할 수 있을 것이다. 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.

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.

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.

Objectives : This study was designed to find possible effect of pregnancy and parturition on spatial memory, especially in relation to levels of estrogen during the third trimester and postpartal period in rats. Methods : 25 female Sprague Dawley rats were divided into pregnant group (N= 14) and control group (N= 11). Changes in spatial memory during 6 weeks including third trimester and postpartal period were measured using Morris water maze. Time to reach the platform in the maze was indicator of spatial memory. Serum estrogen level was measured on 1 week before delivery, postpartal day 1, and day 14. Results : Both groups showed gradual improvement in performance by trial days and weeks, but no significant difference was found between the two groups. However in the third trimester, pregnant group showed a trend of less achievement on 3 days of learning than control group. Serum estrogen levels did not differ significantly between groups over the 6 weeks of period. However there was positive correlation between serum estrogen level on postpartum day 1 and time to reach platform on postpartum week 2, and negative correlation between estrogen level on postpartum day 14 and latency to the platform on postpartum week 5. Conclusion : These results imply that changes in the serum estrogen level may have dual effects on the spatial learning in peripartal period. It is suggested that decline in cognitive function might occur either by failure of rapid decrease of estrogen, immediately after parturition, or retarded restoration of estrogen in later postpartal period.

Usual interstitial pneumonia(UIP) is relatively rare disease of lung parenchyme under the age of 50. Lung cancer is reported to occur as a complication of UIP, but has not been reported in young age patient with UIP in Korea. A 35-year-old man was admitted to the hospital because of dyspnea, cough and mild fever. He had been suffered from dyspnea during 3 years. The dyspnea worsened recent 1 month ago. He had been treated with pneumonia at another hospital during 4 months before this admission. Chest radiographs and High resolution CT showed subpleural and basal dominant reticular opacities in both lung with no change until now. He was smoker and his occupation was car engine-man dealing with benzene. UIP is suspected by history and radiologic findings. Operation for open lung biopsy was performed to obtain lung specimen via video-assisted thoracoscopic surgery. Patient's pathologic examination showed UIP combined with adenocarcinoma in RLL superior segment and posterobasal segment and RLL lobectomy was done. After operation, the patient has been in cancer free condition so far. We report a case of UIP combined with lung cancer in young man with brief review of the literature.

This study aims at revealing the physiological responses of dehydration (DH) and rehydration (RH) in intermittent exercises at the work intensity of 70% HR max. First, with general student public, three times of exercise (each for 20 minutes) at the given work intensity were taken, with a break for 25 minutes respectively. Their heart rate, rectal temperature and plasma electrolyte concentration both DH and RH were measured. Second, in two groups of athletes and non-athletes, 9 rounds of exercise (for 100 minutes) and 8 breaks (for 60 minutes) were taken, with RH forced 10 times to compensate for the subjects' water loss. Their change in sweat loss and plasma electrolyte concentration as well as the IVDP(Intensive Voluntary dehydration Phenomenon) were experimented. The summary of this research follows. 1) Mean heart rate and rectal temperature in intermittent exercises were higher at DH than at RH, growing up at the increasing level of DH. 2) RH saw no change in the plasma concentration of Na+, K+ and Cl-, while DH observed a significant increase. 3) HCO₃made a significant decrease at DH before growing up. 4) Mg++ had no change, while Ca++ increased significantly at RH and DH. 5) Lactate showed an increase with significance at RH and DH, especially greater at DH. 6) Osmotic pressure increased meaningfully at DH. 7) Anion gap increased significantly at DH and RH. 8) On the other hand, when the forced RH was held, the group of athletes had greater sweat loss per body surface area than that of non-athletes. 9) The athletes' plasma concentration of Na+ and Cl- revealed a clear decrease. 10) There was seen no significant change in the plasma concentration of K+, Mg++ and Ca++ in both groups. 11) The IVDP occurred at the RH of 2.3ℓfor athletes and more than 2.5ℓfor no-athletes.

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.

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.

We introduce a cost-effective method that combines electroplating with metal cold working processes to manufacture compositetubes with robust corrosion resistance. First, a 3-step electroplating process was developed to form an adhesive anduniform Ag coating on the outer wall of a 304 stainless steel tube. The process consisted of a Ni-strike step for removing thepassivation layer of the initial 304 tube, Cu deposition for smoothing the surface by adding a buffer layer, and Ag deposition. To reinforce the interfacial adhesion between the electroplated layers and the 304 tube and increase the area of the Ag coating,a pilger rolling or pilger rolling + heat-treatment process was performed after the Ag electroplating process. Scanningelectron microscopy of the composite tubes after each process indicated that the as-deposited Ag coating changed fromhaving a rough to smooth surface after only pilger rolling and with additional heat treatment. Electron backscatter diffractionanalysis of the microstructures and textures of the tubes revealed that dynamic recrystallization occurred extensively duringpilger rolling, resulting in the formation of a relatively defect-free grain structure without heat treatment. Furthermore,electrochemical polarization curves determined that the Ag-coated composite tubes are superior to the uncoated 304 tubein terms of corrosion resistance under Cl−atmosphere, owing to the formation of a AgCl passivation layer during testing. Surface analysis of the composite tubes suggests that the properties of the AgCl passivation layer are related to the grainsize of the Ag coating and the density of plastic-deformation-induced defects.
