  • The purpose of the Follies that were constructed for the Gwangju-Biennale were for urban regeneration, to activate the empty old-town areas, and to strengthen the tradition and sense of place of the city. However, the ten Follies constructed around the wall of the old castle reveal many problems including that of leaving Follies alone instead of actively using them, damage to shop-keepers nearby, and pedestrian inconvenience, which is different from the original purposes. This study is meant to help understand the source of the negative phenomena, and to offer plans that will be conductive to the role of urban regeneration through activating the Follies and the spaces around them. As results of the investigation, there was no context giving uniformity among the various Follies. Also, the study showed that the insufficience of designers' understanding of the circumference near the Follies and lack of a consensus between the citizens and designers in the process of making the Follies. The crucial solution for solving these problems, and bringing to life the original purpose of creating the Follies was derived as applying "human activity" to the Follies. This study suggested 'street performance' as an effective device for application to human activity. While a Folly has no fixed function, the development of space program categories based on the applied characteristics of each Folly, and the simulation thereof showed effective potential for attracting people and activating those stagnated spaces. Recently, Gwangju city depicted the second Follies in applications such as reading roon, toilet, and movable food cart, which have clear purpose and different characteristics from the first ones. However, the first Follies will not be moved or demolished. As they are located around the National Asia Culture Center, some of them are supposed to be used to view the center. Consequently, a counterplan for the continuous and efficient use of those Follies is needed. Gwangju has a plan for the installation of 100 Follies throughout the city and it is expected that this study will be a meaningful guide line for improved Follies in the future.

  • Although recent policies and regulations in Korea strongly advocate and encourage cultivation of venture foundations, studies on venture foundation and success are very limited and often primarily focus on entrepreneurship or individual quality as a venture founder in addition to such studies' validity in question. Therefore, this study primarily focuses on venture preparation process which is subject to venture founder's effort to verify the policy effectiveness in the relationship between venture preparation and business performance. Major goal of this study is to reduce social cost of venture failure by suggesting systematic policy support for venture foundations and analyzing the relationship between following variables: first, venture preparation and financial performance, second, venture preparation and non-financial performance, and third, venture preparation and business performance. 400 initial venture foundations less than 5 years are selected from KISED(Korea Institute Startup & Entrepreneurship Development) trend analysis to carry out statistical analysis using SPSS 18.0. To organize the data features, frequency analysis as well as descriptive statistics are performed to verify the hypothesis. As a result, sub-factors in measurement of venture preparation which are venture education period, venture benefit, and experience of incubating organization are selected as independent variables. Likewise, sub-factors in measurement of business performance which are financial performance and non-financial performance are used as dependent variables. To validate interactive effect, venture preparation period is selected as control variable to perform hierarchical regression analysis. The analysis result verifies that venture benefit has positive influence on financial and non-financial performance while venture education period has positive influence on non-financial influence and experience of incubating organization has negative influence on non-financial performance without influence on financial performance. In addition, interaction of venture preparation period has positive influence solely between venture benefit and non-financial performance. Through this study, appropriate supporting plans depending on the level of venture preparation can be derived to improve business performance of initial venture foundations for policy designer of venture support, and quality rather than quality improvement of venture businesses is possible through investigation of structural issues of individual venture businesses. Ultimately, this study suggests venture founders to determine whether to focus on venture preparation process or to start a venture business.

  • BizCool is an entry-level business education program implemented with a purpose of enhancing the entrepreneurial disposition and capability of the youth through enterprise commencement education of vocational high school students and developing them into economic pillars of future to alleviate the labor shortage crisis of small and medium enterprises and revitalize enterprise commencement. In this study, the factors were deduced and a path analysis was conducted with the purpose of proposing a revitalization plan through an effectiveness analysis of enterprise commencement education for the youth. The result of the analysis revealed that BizCool has effects on the knowledge and understanding of enterprise commencement, and enterprise commencement knowledge also has effects on the understanding of enterprise commencement. In addition, it was found that the enterprise commencement knowledge and the understanding on enterprise commencement have effects on the intention of enterprise commence. In the result of verifying the hypothesis that the understanding of enterprise commencement according to the psychological characteristics of individuals will have a positive effect on the enterprise commencement intention, it was revealed that the risk resignation disposition and patience for ambiguity are having effects but accomplishment desire is not playing a moderating variable role. Through the above path analysis, a conclusion was obtained that the enterprise commencement education has effects on the outcome of enterprise commencement education through the understanding on enterprise commencement. Additionally, the nation needs to actively lead systematic enterprise commencement education within the policy of job creation upon realizing the need for enterprise commencement education of vocational high school, and a revitalization plan was proposed on the five kinds of a conversion of social perception on vocational high school, establishment of institutes specializing in BizCool and cultivation of BizCool specialists, development of various materials and expansion of BizCool program, field-centered lessons, revitalization of enterprise commencement club and personnel and resource support by companies.

  • This study was conducted to investigate the difficulties of dairy farms in practicing 6th industrialization and methods for overcoming these difficulties. A qustionnaire survey was carried out to examine the present states of farms, recognition of the farmstead milk-processing market situation, possibility of farmstead milk processing for reducing the raw milk surplus, assessment of government policies, and difficulties dairy farmers confront in realizing the 6th industrialization. Farm sizes, types, and human resources organizations varied between farms. Most farmers were producing yogurt and/or fresh (string or barbecue) cheeses, which were marketed through 'Visit and Purchase' channel. Farmers who answered the questionnaire were relatively positive about the current situation of farmstead milk processing, expecting to be involved in the disposal of excess raw milk. Nevertheless, they responded negatively about current relevant policies, citing the main difficulties caused by 'excessive regulation'. Other barriers to successful '6th industrialization' are difficulties in marketing and lack of funds. Approximately 19% of dairy farms practicing the '6th industrialization' use automatic milking system (AMS) and 38.46% of dairy farmers whose milking depends on conventional milking system intend to introduce AMS in the future. Positive expectations of AMS adoption were mostly related to 'lack of time and labor', 'exhibiting for tourism', and 'succession of dairying'.

  • In 1998, because of the economic crisis called IMF Crisis in Korea, Kyungbu high speed railway project could run by modifying the original plan to open it as a 1st phase only by utilizing the existing railway lines from Seoul to Siheung and the other one from Daegu to Pusan. The modified plan includes that the line from Daegu to Pusan will be constructed as a second phase in next time. Starting railway operation with the changed plan, the combined application operation of high speed rail, passenger rail and freight rail was caused partly from Seoul to Siheung to run into capital area. As a result, the opinion for additional railway line construction is insisted continuously because the operation volume of passenger rail was forced to be reduced, the service quality of it was decreased and it became difficult to add new high speed services. Moreover, with regard to Honam high speed rail, the new construction plan of station in Kangnam metro area as a basement station for starting from Suseo was changed to the plan of turning out at Osong because of the economic effectiveness and this kept resident people in Kangnam metro area and southern Kyungki area unable to get the opportunity of high speed rail service benefit. After beginning of Kyungbu high speed railway operation, national transportation system developments are focused on high speed rail, and when the second phase construction of Kyungbu high speed rail, beginning operation of Kyungjeon line, Jeolla line double track construction, Honam high speed rail in 2014, is completed, the demand for high speed rail will be increased and it is unavoidable to make Kwangmyung station as a basement station and to reduce the number of passenger rail operation. At this moment, it is valuable to consider adding the railway line capacity in capital area to improve the transferring service for citizen who live in area without Kyungbu high speed rail station and to expand the service area from Kangbuk to Kangnam and southern Kyungki area. Accordingly, in this paper, the effective rail operation method, facility plan and the other issue to be reviewed for increasing capital high speed railway lines will be mentioned.

  • 장안초등학교는 한국전쟁 이후인 1955년에 개교된 초등학교이다. 처음에는 8학급의 가교사시설에 18학급으로 편성되어 초기부터 시설이 양적으로 부족하였다. 또한 이 지역의 학생수 증가로 거의 매년에 걸쳐 학급수의 증가와 교실증축이 함께 이루어 졌다. 현재 건물의 건립년도를 살펴보면 1965년 6월에 처음 신관 1층 부분이 건설되어 70년대와 80년대에 걸쳐 꾸준히 증축되어 왔으며, 대지 동측의 별관은 1993년 12월에 건설된 새건물로, 학교교사 건물이 30년된 건물과 최근의 건물이 함께 공존하고 있다. 철근콘크리트 건물이 구조적으로는 100년도 견딘다 하지만 실제로는 약 30년이면 콘크리트의 산성화가 가속화되면서 구조적으로 안전하지 못하다는 학설이 인정되어, 최근 30년이 경과된 학교 건축의 재건축이 사회적 문제로 대두되고 있다. 실제로는 25년이상 경과된 건물에서도 구조적인 하자가 발생하는 예 가 많아 교육부에서는 대체로 25년이상 경과된 건물에 대하여 재건축을 실시하고 있다. 장안초등학교는 20년에서 30년 경과된 건물이 많은 부분을 차지하는 관계로 재건축이 실시되는 예이다. 아직까지 사용이 가능하다고 판단되는 건물은 본관의 남측부분의 교사(1983년 증축)과 신관의 우측부분(1985년 9월 23일 증축)과 별관(1993년 12월 14일 신축)교사동을 들수 있다. 때문에 이 부분에 대하여 철거할 것인가 혹은 그대로 사용할 것인가에 대한 의견이 있어, 최종적으로 별관은 그대로 사용하는 것을 원칙으로 하고 본관 남측부분은 가장 마지막 건설시기에 철거하고 신관 우측부분은 규모가 작아 철거하기로 하였다. 학교건축은 다른 일반건물과는 달리 교육이라는 기능을 충분히 발휘할수 있는 공간구성이 필수적이라 할수 있다. 여기서 말하는 교육이란 예전의 주입식 교육이 아니라 21세기를 바라보는 정보화 세계화를 지향하는 교육으로 학생 개개인의 창의성과 자주성을 발휘시킬수 있는 교육이라는 점에 대하여 의견은 없을 것이다. 이러한 교육이란 다양한 교육방법을 전제로 하며 하나의 학년을 하나의 학습그룹으로 생각하는 것은 중요한 출발점이 될 것이다. 한 학년의 그룹을 교대상의 기본으로하여 이러한 그룹에 대하여 일제학습, 그룹학습, 팀티칭, 개별학습이 이루어 질수 있는 공간을 제공하는 점을 본 장안초등학교 기본계획에서 출발점으로 하였다. 물론 학교전체 학생을 콘트롤할 수 있는 교육방법도 존재한다. 선진 외국의 예를 살펴보면 아동의 능력별 교육을 위하여 무학년제(Non-Grade)를 도입하는 경우도 있지만 아직 우리나라에서는 학급단위가 중요시되고 있다. 이 학급단위는 교육단위이면서 생활지도 단위이기도 하다. 이러한 점을 인식하여 학교건축의 간장 기본 단위가 되는 보통교실 계획을 보통교실과 오픈스페이스를 연속시킨 유니트로 계획하여 일제학습, 그룹학습, 팀티칭, 개별학습 등이 이루어 질수 있도록 하였다. 실제로는 36학급을 계획할 경우, 한학년의 6개 학급이 하나의 공통된 공간내에 그룹핑 되는 것이 바람직하지만(제3안의 배치에서 제안하여 보았지만 북측교실, 오픈스페이스의 통로화등의 문제점이 있었다), 그 규모가 너무 커서 3개학급을 하나의 유니트로 하였다. 물론 한학년이 동일한 층에 배치시켜 서로의 관련성을 높게 하였다. 특별교실 계획은 보통교실과의 관련성과 장래 지역개방의 역할을 고려하여 계획하여야 할 것이다. 장안 초등학교의 경우는 별관을 그대로 사용 한다는 조건이 있기 때문에 기존의 편복도 형식의 교실에서는 보통교실 계획의 어려움이 있어 특별 교실동으로 고려하였다. 때문에 지역개방에 대해서는 문제점을 안고 있다. 체육관은 기준령에는 권장시설로 되어 있지만 학교시설에 필수적인 시설이라 생각한다. 체육은 국민건강에 직결되기 때문이다. 또한 체육관 건설은 실외체육 실내체육에 대응할 뿐 아니라 학교 행사등에 유용히 사용되기 때문에 더욱 필요시설이라 할수 있겠다. 또한 지역개방을 위하여 정문 혹은 후문 가까이에 배치시키는 것은 필수적이다. 별관, 체육관, 운동장, 후문측에 12학급용의 단독건물 등의 기본적인 제약조건을 고려하여 배치하자면 자연히 교실동들이 분산되는 결과를 낳게된다. 이러한 각각의 교사동을 A동을 중심으로 구름다리로 연결하여 동선의 불편함을 해소시켰다. 주차장은 후문 가까이에 약 10정도의 주차공간이 확보가능하다. 이외에는 운동장을 사용하는 방법과 체육관의 1층부분을 필로티로 하여 그곳에 20대 정도 주차시키는 방안이 있다. 주차는 많을수록 편리는 하겠지만 제한된 대지에 모두 만족 시켜주기는 불가능하다. 공공용의 주차와 소방에 필요한 동선이 요구된다. 특히 도심주차난을 생각할 때는 차라리 적극적으로 지하주차장을 계획하는 방안이 있을 것이다. 마지막으로 현재 67학급은 초대형 규모로 초등학교 규모로는 적합하지 못하다. 장래를 고려하여 48학급에서 최종적으로 36학급으로 계획하였으나 한동안은 67학급이 그대로 유지될 것으로 보인다. 신설 초등학교가 가까운 시기에 개교될 것을 기대한다.

  • The purpose of this study is to explore the occupational personality required for high school graduates and to develop a scale to measure them objectively. In order to achieve the purpose of the study, this study constituted the delphi committee composed of the teacher group and the industrial personnel group. Afterwards, Delphi survey was conducted twice, and it was found that 12 jobs such as sincerity and honesty were related to occupational personality. As a result of the development of the scale based on the previous research and the expert group interview, 12 factors and 116 scales were developed for the pre - occupational personality test tool. In order to verify the validity and reliability of the developed preliminary test tool, we conducted a questionnaire survey of 700 students of vocational high school, and 514 questionnaires were used for final analysis. Parallel analysis was performed to determine the number of factors before exploratory factor analysis. As a result, eight factors were found to be appropriate. As a result of exploratory factor analysis using the 'maximum likelihood method' and 'direct oblimin rotation method', 78 items of 8 factors were found appropriate. However, in order to confirm whether the item reflects the contents of the factors, we conducted a content validity test for the expert group. As a result, feedback was obtained that 19 items were irrelevant or inadequate. Therefore, the validity of the existing job personality test tool and the modified job personality test tool were verified through confirmatory factor analysis. As a result, the fitness of the revised test tool was higher and the fitness level was generally good.

  • Corona 19 brought about a major shift in the Korean church's pastoral style. Contact and non-contact ministry styles using the Internet and media devices are being held together. The elderly, who have been classified as digital vulnerable, need to see whether they are properly adapting to these changes and they have any difficulties in their religious lives. This study is to organize the current status of Corona 19 related to Korean churches, look at the current state of church programs for Christian elderly people, look at how important the religious life is to their lives, and to suggest educational pastoral methods for their religious lives based on the theory of Maria Harris' educational ministry. First, in terms of Koinonia, it was suggested that the heritage, beliefs, values and ways of life held by the Christian elderly be shared with people inside and outside the church in order to entertain and embrace everyone without alienation. Second, from the perspective of Leiturgia, educational ministry was proposed to expand prayer life from a personal area to a public area to become a life of practicing prayer and justice by providing public prayer content with media that can be used by the elderly to perform spirituality. Third, it was suggested that in terms of Didache, it should be required that the elderly should be educated to be familiar with the changing technologies, that teaching environment should be extended from church to online, and that the educational content of tradition and new forms should be dealt with extensively. Fourth, from the perspective of Kerigma, Christian elderly people who have suffered in various life environments, both personally and socially, should listen to the words again and gain the power to overcome the corona crisis through the God's words, so that they can be melted into the curriculum of koinonia, leiturgia, didache, and diakonia. Fifth, it was suggested that senior citizens should switch their consciousness to become subjects of service, not objects of service, and that digital literacy education should be provided individually at eye level to narrow the digital gap for Diakonia curriculum.

  • Gulpur 수력발전 프로젝트는 전력난을 겪고 있는 파키스탄에 102 MW 규모의 수력발전소를 건설하여 30년 동안 운영 관리한 후 파키스탄 정부로 양도하는 IPP(Independent Power Producing) 형식의 투자사업이다. 남동발전과 DL E&C, 롯데건설이 Sponsor로서 출자한 자본금과, ADB, IFC, K-EXIM 등의 대주단로부터의 차입금을 재원으로 하여 소요 사업비를 조달하고 사업을 개발하였다. DL E&C와 롯데건설이 EPC(Engineering, Procurement, Construction)를 수행하였고, 이산이 Design consultant의 역할을 수행하였다. Gulpur 수력발전 프로젝트의 발전형식은 수로식(run-of-river)으로 201 m3/s의 발전유량과 102 MW의 발전 시설용량을 이용하여 연평균예상발전량은 398 GWh이다. 주요 구조물로는 설계 재현빈도 1년의 유수전환시설(가물막이댐 & 가배수터널)과 콘크리트 중력식댐(H 67 m, L 205 m), 도수터널(D 6.7 m, L 215 m, 2기), 옥외형 발전소 (H 51 m, W 60 m, L 38 m, Kaplan 2기)가 있으며, 2015년 10월 착공하여 2020년 3월 상업발전을 시작하였다. 본 프로젝트는 DL E&C의 첫 번째 EPC 해외수력발전 프로젝트이다. 따라서 프로젝트의 성공적 수행을 위한 경제적 설계, 시공의 효율성 및 안정성 확보 등을 위하여 많은 연구를 수행하는 과정에서 다양한 기술 개선을 이룰 수 있었다. 본고에서는 Gulpur 프로젝트를 통하여 도출된 성공 사례들을 소개 및 공유하고자 한다. 첫 번째로 콘크리트 중력식댐 시공을 위한 유수전환시설의 최적 설계빈도를 산정하였다. 일반적으로 유수전환시설의 규모는 설계기준에 제시된 설계 재현빈도를 이용하는데, 해외 설계기준에서는 10년, 국내 설계기준에서는 1~2년으로 다르게 제시되어 있는 문제점이 있다. 유수전환시설의 규모는 프로젝트의 경제성에 큰 영향을 미치기 때문에 최적 설계빈도의 결정이 필요하며, 위험도분석기법(Risk Analysis)과 기대화폐가치법(Expected Monetary Value)을 이용하여 유수전환시설의 최적 설계 재현빈도와 이에 영향을 미치는 인자를 분석하였다. 위험도는 몬테카를로 시뮬레이션으로 산정된 가물막이댐 파괴확률과 재현빈도를 이용하여 산정된 가물막이댐 월류확률을 고려하였으며, 비용 및 피해액으로는 유수전환시설의 공사비, 가물막이댐 파괴시의 재건설비용과 지체보상금, 가물막이댐 월류시의 복구비용을 고려하였다. 이에 대한 연구결과로, 유수전환시설의 사용기간과 월류시의 복구비용이 유수전환시설의 설계 재현기간 결정에 가장 큰 영향을 미치는 것으로 나타났고, 특히 월류시의 복구비용이 작을수록 낮은 설계 재현빈도를 선택하는 것이 타당한 것으로 나타났다. 예를 들어, 유수전환시설의 사용기간이 3 ~ 5년, 복구비용이 0.5 ~ 1.0 mil USD 이하인 조건에서 가물막이시설의 최적 설계빈도는 1년 ~ 2년인 것으로 나타났다. 또한, 유수전환시설의 사용기간은 본댐의 규모와 시공기간 등을 고려하여 결정되는 사항으로 설계자가 임의 조정할 수 없지만, 복구비용은 시공 관리자에 따라 결정되는 부분으로, 적극적 홍수 피해 저감 및 복구방안을 마련하는 것이 프로젝트의 경제성을 향상시킬 수 있다는 것을 알 수 있었다. 두 번째로 프로젝트의 경제성 향상, 홍수기 댐 시공시의 안전성 확보를 위하여 홍수 조기경보시스템(Early Warning System)을 개발 및 활용하였다. 수로식(Run-of-river) 수력발전댐은 대부분 산악지역에 위치하기 때문에 국지성 강우 및 급한 지형 경사로 인하여 돌발홍수(flash flood)의 발생 가능성이 높다. 따라서 시공 중 홍수(월류) 발생을 미리 감지하고 현장에 전파할 수 있는, 수로식(Run-of-river) 수력발전댐 현장을 위한 홍수 조기경보시스템이 필요하며, 이를 리스크 인식, 모니터링 및 경보, 전파 및 연락, 반응 능력 향상의 4가지 부분으로 나누어 구축하였다. 리스크 인식 부분에서는 가물막이댐 월류 발생 상황에 대한 위험도, 취약성, 리스크를 제시하였으며, 모니터링 및 경보 부분에서는 상류 측정수위에서 유도된 현장 예상수위와 실제 현장 측정 수위를 대상으로 경보홍수위와 위험홍수위로 나누어 관리하였다. 전파 및 연락 부분에서는 현장 시공 조직을 활용하여 홍수시를 대비한 비상연락체계도(Emergency communication flow chart)를 운영하였으며, 반응 능력 향상을 위해 비상연락체계도의 팀별 Action plan을 상세화 하였다. 세 번째로 현장의 지질특성과 50여 차례 발파시험으로 현장 고유의 발파진동감쇄곡선을 도출하였으며, 이를 통해 현장의 시공성과 콘크리트 품질 확보를 동시에 달성할 수 있는 방안을 제시하였다. 콘크리트댐 공사에서는 제한된 공기 내에 공사를 완료하기 위해 사면부 굴착과 콘크리트 타설이 동시에 수행될 수밖에 없는 문제점을 가지고 있다. 그러나 신규 콘크리트 타설면 근처에서 발파를 수행하는 경우 발파로 발생되는 탄성파가 일정 수준을 초과하게 되면, 콘크리트 양생에 영향을 주게 된다. 따라서 다수의 현장 발파시험을 통해 발파거리와 최대진동속도의 상관관계 즉, 발파진동감쇄곡선을 도출함으로써 현장의 발파진동특성을 도출할 수 있었다. 또한, 기존 연구 논문들을 통해 콘크리트 재령기간 별 안전진동속도를 선정하고, 해당 안전진동속도를 초과하지 않는 범위에서 콘크리트 타설면과 발파위치의 거리에 따라 1회 발파 가능한 장약량을 산정하여 적용하였다. 이와 같은 체계적인 접근을 통해 콘크리트 타설과 발파 작업 동시 수행에 대한 논란을 해소할 수 있었다.

  • The purpose of this study was to utilize the Photovoice qualitative research method targeting university students. Through this method, we aimed to understand the perceptions of environmental issues, environmental barriers, and eco-friendly behaviors among university students. By employing the Photovoice methodology, we sought to share the perspectives of university students on eco-friendly behaviors, explore the motivations and manifestations of these behaviors, and reflect on their significance. The ultimate goal was to provide practical suggestions for fostering eco-friendly behaviors through an in-depth examination of the visual narratives and reflections of university students. Under the overarching theme of the environment, participants were given the opportunity to individually select and explore three specific sub-themes: 'My Concept of the Environment,' 'Environmental Barriers in My Life,' and 'My Eco-friendly Behaviors.' Participants engaged in the process of capturing photographs from their daily lives related to each theme, expressing their thoughts and perspectives through the selected images. Subsequently, they shared and discussed their insights, actively listening to the opinions of others in the group. The results of this study revealed several key findings. Firstly, participants assigned meaning to the photographs they selected by directly capturing aspects related to the environment, such as 'waste,' 'discomfort,' 'fine dust=environmental pollution,' and 'indifference.' Secondly, participants attributed meaning to the selected photographs related to environmental barriers, associating them with concepts like 'invisibility,' 'apathy,' 'social stigma,' 'inefficiency,' and 'compulsion.' Lastly, participants ascribed significance to photographs selected in the context of eco-friendly behaviors, with themes like 'recycling,' 'energy conservation,' 'reuse,' and 'reducing the use of disposable items.' Based on these research findings, the confirmation of the V-A-B (Values-Attitudes-Behavior) model was established. It was observed that consumers structure a hierarchical relationship between their personal values, attitudes, and behaviors. The study also identified clear impediments in consumers' daily lives hindering the practice of eco-friendly behaviors. In light of this, the research highlighted the need for strategies to address the discomfort or inconvenience associated with implementing environmentally friendly consumer behaviors. The implications of the study suggest that interventions or solutions are necessary to alleviate barriers and promote a more seamless integration of eco-friendly practices into consumers' daily routines.
