          이용자간 만족도를 고려한 공원의 공간개선 방향연구 - 목포시 삼학도공원을 중심으로 -

          박성현 ( Park Sung-hyun ),배현미 ( Bae Hyun-mi ) 한국도서(섬)학회 2020 韓國島嶼硏究 Vol.32 No.4

          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.

          도시의 모험놀이터‘플레이파크’에 관한 고찰

          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.

          MVPT-R을 이용한 한국과 미국 전학령기 아동의 시지각 능력 비교를 위한 기초 연구

          박성현,박소정,박수희,정혜림,장문영,Park, Sung-Hyun,Park, So-Jung,Park, Soo-Hee,Jung, Hye-Rim,Chang, Moon-Young 대한감각통합치료학회 2005 대한감각통합치료학회지 Vol.3 No.1

          Objective : The purpose of this study was to indicate the foundational data to standardize MVPT-R for Koreans. Method : This study was conducted on 221 children ranging in all preschool age from 4 to 6 years residing in Busan and Kyungsangnam-do. It was performed from January 12, 2004 to April 30, 2004. Result : First, similar to American children, as Korean children grow older, the mean raw score of MVPT-R increased. Second, Korean children's mean raw score was higher than that of American children; 3.51 in 4 age, 1.52 in 4.6 age, 2.93 in 5 age, 1.72 in 5.6 age, 1.84 in 6 age and 0.48 in 6.6 age. Third, the mean of PQ(106.57) in Korean children was higher than that of PQ in American children. Fourth, The raw score in Korean children was higher than the raw score in American children in most of the subjects(excluding visual closure subjects). Conclusion : The visual perception skill of Korean children is higher than that of American children. If we apply MVPT-R developed in U.S to Korean children, it will be difficult for Korean children to achieve the adequate results. Therefore, we must use the standardized MVPT-R for Korean that can minimize the differences between American and Korean children's visual perception skills.

          Camphene/WO<sub>3</sub>-NiO 슬러리의 동결건조 및 수소분위기 열처리에 의한 W-Ni 다공체 제조

          박성현,박성민,박소정,박보영,오승탁,Park, Sung Hyun,Park, Seong-Min,Park, So-Jeong,Park, Bo-Yeong,Oh, Sung-Tag 한국재료학회 2018 한국재료학회지 Vol.28 No.2

          The present study demonstrates the effect of raw powder on the pore structure of porous W-Ni prepared by freeze drying of camphene-based slurries and sintering process. The reduction behavior of $WO_3$ and $WO_3-NiO$ powders is analyzed by a temperature programmed reduction method in Ar-10% H2 atmosphere. After heat treatment in hydrogen atmosphere, $WO_3-NiO$ powder mixture is completely converted to metallic W without any reaction phases. Camphene slurries with oxide powders are frozen at $-30^{\circ}C$, and pores in the frozen specimens are generated by sublimation of the camphene during drying in air. The green bodies are hydrogen-reduced at $800^{\circ}C$ and sintered at $1000^{\circ}C$ for 1 h. The sintered samples show large and aligned parallel pores to the camphene growth direction, and small pores in the internal wall of large pores. The strut between large pores, prepared from pure $WO_3$ powder, consists of very fine particles with partially necking between the particles. In contrast, the strut densification is clearly observed in the Ni-added W sample due to the enhanced mass transport in activation sintering.

          진공 인라인 실장에 의해 제작된 플라즈마 디스플레이 패널의 전기적ㆍ광학적 특성

          박성현,이능헌,Park, Sung-Hyun,Lee, Neung-Hun 한국전기전자재료학회 2005 전기전자재료학회논문지 Vol.18 No.4

          The optical and electrical characteristics of plasma display panel(PDP) using the vacuum in-line sealing technology compared with the conventional sealing process in this research. This PDP consisted of MgO protecting layer by e-beam evaporation and battier rib, transparent dielectric layer, dielectric layer, and electrodes by screen printer and then sealed off on Ne-Xe(4 %) 400 Torr and 430。C. The brightness and luminous efficiency were good as the base vacuum level was higher, and it was to check the advantage of high vacuum level sealing, one of the strong points of the vacuum in-line sealing process. However, the brightness and luminous efficiency was dropped sharply because of a crack on MgO protecting layer by the difference of the expansion and contraction stress on high temperature in the vacuum states between MgO and substrate. Fortunately, the crack was prevented by MgO was deposited on higher temperature than 300。C. Finally, the PDP, was fabricated by the vacuum in-line sealing process, resulted the lower brightness than processing only the thermal annealing treatment in the vacuum chamber, but the luminous efficiency was increased by the reducing power consumption with the decreasing luminous current. The vacuum in-line sealing technology was not to need the additional thermal annealing process and could reduce the fabrication process and bring the excellent optical and electrical properties without the crack of MgO protecting layer than the conventional sealing process.

          박성현,김수환,신천우,Park Sung-Hyun,Kim Soo-Hwan,hin Cheon-Woo 한국통신학회 2005 韓國通信學會論文誌 Vol.30 No.9a

          본 논문은 NRD 가이드를 이용하여 10km이상의 장거리 무선통신이 가능한 밀리미터파 대역용 FM 송신기 및 수신기를 제작하였다. 40GHz 사용주파수의 반파장 크기의 간격을 가지는 상하도체판 사이에 PTEE 유전체선로상에 건발진기, FM변조기 및 안테나로 구성된 FM 송신기를 제작하고, 동일한 간격을 가지는 상하도체판 사이에 국부발진용 건발진기, 밸런스믹서, 3dB 방향성결합기 및 안테나로 구성한 FM 수신기를 각각 제작하였다. 또한 제작된 FM송신기 및 수신기를 이용하여 무선통신 영상전송시험을 실시하였다. 이때 전송거리 10km의 시험거리에서 영상신호를 송신측에서 보낸 후 수신측의 TV 수상기를 통해 선명한 영상을 실시간으로 재생할 수 있었다. 이에 개발된 40GHz 대역 FM 송신기 및 수신기는 CATV의 전송이나 광대역 전송이 필요한 무선통신 시스템으로 사용이 가능하며, 장거리 초고속통신망의 연결 장치로 사용될 수 있을 것이다. In this paper, we fabricated along distance wireless communication transmitter and receiver over the 100 which used NRD technology. To make the transmitter and receiver of 400Hz band using the non radiative dielectric wave guide, transmitter was composed of gm oscillator, m modulator and antenna, receiver was composed of local gum oscillator, balanced mixer, 3dB direction coupler and antenna. Also we executed a wireless communication image transmission examination to the transmitter and receiver. We receive the image information in real-time data transmission from receiver after we send the image signal in the wireless distance of the 10km. Therefore, the 400Hz band U transmitter and receiver to be developed will be used widely for the transmission system CATV or broadband transmission system. This will be utilized also to the link device of a long distance high speed wireless communication network.

          Thixomolding 공정으로 제조된 Mg-xAl-yZn계 마그네슘 합금의 미세조직과 기계적 물성에 미치는 Ti 첨가 영향

          박성현,장호승,이지호,박노진,오명훈,Park, Sung-Hyun,Jang, Ho-Seung,Lee, Ji-Ho,Park, No-Jin,Oh, Myung-Hoon 한국열처리공학회 2019 熱處理工學會誌 Vol.32 No.4

          The microstructural features and relative room temperature mechanical properties were investigated in various compositions of Mg-xAl-yZn alloys by thxiomolding process. The microstructure was composed of ${\alpha}$-Mg particles and mixture of ${\alpha}$-Mg and ${\beta}-Mg_{17}Al_{12}$ eutectic phase. The amount of ${\beta}-Mg_{17}Al_{12}$ eutectic phase in mixture was increased with increasing Al and Zn contents without grain refinement. After adding Ti content, however, the morphology of ${\beta}-Mg_{17}Al_{12}$ eutectic phase transformed from net-like to discontinuous shape and the average grain size reduced. To determine the relationship between microstructural features and their mechanical properties, a tensile test was performed at room temperature. As a result, it was found that the mechanical properties were improved in all of Ti contained alloys due to increased elongation and the mechanisms are discussed in terms of microstructural evolution.

          운동유형별 뇌졸중 환자의 기능적 수행능력 변화 I : 보행시 하지근육 활성도 분석

          박성현,김정태,Park, Sung-Hyun,Kim, Jung-Tae 한국운동역학회 2008 한국운동역학회지 Vol.18 No.1

          The purpose of this study was to compare and analyze the effects of exercise types on lower extremity muscle activity in stroke patients. For the purpose, the subjects of this study were classified into three groups such as therapeutic exercise group(n=7), elastic band group(n=7), and stretch reflex group(n=7). The three exercise programs were 5 times a week for 8 weeks. The stretch reflex group revealed higher in iliopsoas and biceps femoris %MVIC than the therapeutic exercise group and elastic band group, whereas elastic band group revealed lower in tibialis anterior %MVIC than therapeutic exercise group in the primary single-limb support. The stretch reflex group revealed higher in iliopsoas %MVIC than the therapeutic exercise group and elastic band group, whereas stretch reflex group revealed lower in medial gastrocnemius %MVIC than therapeutic exercise group in the secondary double support phase. 본 연구는 운동유형별 운동 전후 뇌졸중 환자의 보행시 하지근육 활성도의 차이를 비교 분석하여 임상에서 기능적 수행능력의 개선을 위한 효과적인 근력강화 방법을 제시하는데 그 목적이 있다. 이를 위하여 운동치료군, 탄성밴드군 및 신장반사군으로 구분하여 각각 7명씩 총 21명을 대상으로 하였고, 운동프로그램은 8주 동안 주 5회 실시하였다. 1차 단하지 지지기에서 장요근 및 대퇴이두근의 %MVIC는 신장반사군이 운동치료군과 탄성밴드군보다 높은 수준을 보였고, 반면 전경골근의 %MVIC는 탄성밴드군이 운동치료군보다 낮은 수준을 보였다. 2차 양하지 지지기에서 장요근의 %MVIC는 신장반사군이 운동치료군과 탄성밴드군보다 높은 수준을 보였고, 반면 내측 비복근의 %MVIC는 신장반사군이 운동치료군보다 낮은 수준을 보였다. 결론적으로 신장반사 운동은 운동치료와 탄성밴드를 이용한 근력강화 운동 보다 고관절의 안정성 및 하지 분절의 운동성을 제공하는 주요 근육의 활성도에 효과적인 영향을 미침으로써 임상에서 근 약화로 인한 운동 기능이 제한된 편마비 환자에게 실용적으로 접근할 수 있는 운동방법이라고 판단된다.
