고재군,김문기,이신호,Koh, Chae-Koon,Kim, Moon-Ki,Rhee, Shin-Ho 한국농공학회 1985 한국농공학회논문집 Vol.27 No.2

Wasting fiberous residues from the cutting processes of steel materials at an iron-Works were mixed with concrete. The strength and toughness of steel fiber concrete with different steel contents were tested in a laboratory. The test results showed that the steel fiber residues can be used for the reinforcement of concrete. The potential applications of such product include floor constructions for facilities like dairy barns, grain storages, and machinery shops. The test results are as follows. 1. The compressive strengths of steel fiber concrete with one percent steel content by volume were 20 percent greater than that of plain concrete. The treatments also increased the concrete toughness by 96 percent. 2. When applied to tensile forces, the steel fiber concrete showed the increased strengths by 20 percent, and the toughness by 48 percent. 3. The steel content levels greater than or equal to 1.5 percent by volume resulted in the decreases of the compressive and tensile strengths of steel fiber concrete by 10 percent as compared to plain concrete. The concrete toughness increased with the steel contents. 4. The reinforcement effects of steel fiber depend on the quality of fiber material being used. Good steel fiber for concrete reinforcement appears to be uniform in shape and component, fine and long, and round-shaped.

5 ‧ 18정신과 타자를 위한 인간 ―문용동과 본회퍼의 생애를 중심으로

고재길 서울신학대학교 기독교신학연구소 2019 神學과 宣敎 Vol.57 No.-

“타자를 위한 인간”은 히틀러의 나치 정권 하에서 교수형으로 생을 마쳤던 디트리히 본회퍼(Dietrich Bonhoeffer)의 후기 신학에 나타나는 용어이다. 그는 신의 존재를 부정하고 이성의 활동을 절대화하는 20세기의 상황을 고려하면서 하나님의 아들, 예수 그리스도를 십자가에서 죽기까지 자기를 희생하신 “타자를 위한 인간”으로 규정한다. 본 연구는 “타자를 위한 인간”으로 존재하신 예수 그리스도에 대한 신앙을 가지고 살고, 죽었던 두 사람에게 주목한다. 본회퍼와 문용동이 바로 그들이다. 본회퍼가 타자를 위해 죽기까지 희생적인 삶을 사셨던 예수의 참된 제자였듯이, 문용동은 1980년 5월 광주민주화운동의 과정에서 “타자를 위한 인간”의 원형이신 나사렛 예수의 진실한 제자의 모습을 보여주었다. 문용동은 그 당시, 호남신학교의 재학생이었고, 교회에서는 하나님의 말씀을 열정적으로 선포했던 사역자였다. 광주민주화운동의 정신, 즉 5ㆍ18정신과 “타자를 위한 인간”은 서로 긴밀하게 연결되어 있다. 5ㆍ18정신은 “타자를 위한 인간”의 삶에서 발견할 수 있고, “타자를 위한 인간”의 삶은 5ㆍ18 광주민주화운동에서 분명하게 나타났다. 5ㆍ18정신은 반독재민주화 투쟁의 과정에서 나왔다. 5ㆍ18정신 빼앗긴 자유를 되찾고 무너진 평화를 다시 일으켜 세우고, 짓밟힌 인권을 회복하기 위한 선한 가치이다. 문용동과 본회퍼는 “타자를 위한 인간”으로서의 윤리적 삶이 무엇인지 분명하게 보여주었다, 그들의 삶은 하나님사랑과 이웃사랑의 가치 위에 형성되어 있었다. 본 연구는 다음의 성과를 가진다, 첫째, 기독교신앙이란 구체적인 상황 속에서 나타나는 신앙의 행위를 포함한다. 문용동과 본회퍼는 믿음과 행함을 분리시키지 않았고, 행함 있는 믿음의 정수가 무엇인지 제대로 보여주고 있다. 둘째, 문용동과 본회퍼는 기독교신앙에서 중요한 소명과 책임의 중요성을 일깨워주고 있다. 두 사람은 직업으로서의 소명 그 위에 책임의 의미를 더하여 생각한다. 셋째, 문용동과 본회퍼는 “타자를 위한 인간”으로 살았다, 신학의 관점에서 보면 문용동은 깔뱅신학을 따른다. 반면에 본회퍼는 루터신학의 관점을 반영하고 있다. 마지막으로 중요한 것은 우리가 나사렛 출신 그리스도이신 예수의 존재에 참여하고 있는지에 대한 질문이다. 문용동과 본회퍼는 이 질문에 대한 하나의 답을 제시해주고 있다. “The man for the others” is a term in the later theology of Dietrich Bonhoeffer that was hanged under Hitler’s Nazi regime. Taking into consideration the situations of the 20th century characterized by the denial of god and the effort to make reason's activities absolute, Bonhoeffer defined God's son or Jesus Christ as a “man for the others” that sacrificed himself until he died on the cross. This paper focused on two men that lived and died in the faith of Jesus Christ that existed as a “man for the others”: Bonhoeffer and Mun Yong‐dong. Just like Bonhoeffer was a true disciple of Jesus that lived a sacrificing life for others until his death, Mun displayed himself as a true disciple of Jesus of Nazareth, who was the archetype of “man for the others,” in the process of Gwangju Democratization Movement in May, 1980. Mun was a student attending the Honam Theological University and Seminary and minister that proclaimed God's words passionately at church during the movement. There are close connections between the spirit of the Gwangju Democratization Movement or the spirit of May 18 and “man for the others.” The spirit of May 18 can be found in a life of “man for the others,” which is in turn clearly found in the Gwangju Democratization Movement on May 18. The spirit of May 18 stemmed from the process of struggling against autocracy and for democratization. It represented the good values of restoring people’s freedom that was taken away, raising peace that collapsed again, and getting back people’s human right that was trampled. Both Mun and Bonhoeffer clearly showed what was ethical life as a “man for the others.” Their lives were built upon God's love and affection for neighbors. The present study had the following results: first, Christian faith includes the acts of faith manifested in specific situations. Mun and Bonhoeffer did a good job at showing the essence of faith accompanied by actions without separating action from faith. Secondly, they aroused the importance of calling and responsibility that were critical to Christian faith. They added the significance of responsibility to calling as a vocation in their thinking process. Thirdly, they lived as “man for the others.” From a theological perspective, Mun followed Calvin's theology, whereas Bonhoeffer reflected the viewpoint of Lutheran theology. Finally, it is important to ask ourselves whether we participate in the existence of Jesus of Nazareth as Christ. Both Mun and Bonhoeffer offer an answer to this question.

Resilience is the capacity to maintain essential services under a range of circumstances from normal to extreme. It is achieved through the ability ofassets, networks, systems and management to anticipate, absorb and recover from disturbance. It requires adaptive capacity in respect of current andfuture risks and uncertainties as well as experience to date. The agricultural infrastructures with high resilience can not only reduce the size of thedisaster relatively, but also minimize the loss by reducing the time required for recovery. This study aims to evaluate the most suitable droughtcountermeasures with the analysis of various resilience indices by predicting future agricultural water shortage under land use and climate changescenarios for agricultural areas in Jeju Island. The results showed that the permanent countermeasure is suitable than the temporary countermeasuresas drought size and the cost required for recovery increase. Wide-area water supply system, which is a kind of water grid system, is identified as themost advantageous among countermeasures. It is recommended to evaluate the capability of agricultural infrastructure against drought with the variousResilience Indices for reliable assessment of long-term effect.

남북한 경제협력 클레임 현황과 개선방안에 관한 연구

고재길 한국중재학회 2019 중재연구 Vol.29 No.4

This study is aimed at drawing up improvement measures in connection with the resolution of claims, one of the major constraints in revitalizing South-North Korean economic cooperation. To that end, we first looked at the structure of South-North Korean economic cooperation and the institutional status related to resolving the claims. Also we analyzed the current status of the claims in the process of promoting South-North Korean economic cooperation by companies and the provisions of the claims between the parties in order to derive any problems. Through these research results, we were able to identify directions and implications for efficient improvement of the causes of several South-North Korean economic cooperation claims. First, at the corporate level, there is a need to create specific details of a contract for resolving disputes and to add additional third-party coordination functions in the relevant clause of the contract in preparation for the occurrence of a dispute. In addition, it is necessary to seek ways to advance jointly with corporations in China and other third countries in order to secure stability. Second, the government should continue to discuss ways of promoting South-North Korean commercial arbitration with North Korea so that follow-up measures can be completed as soon as possible. In addition, a two-track strategy is suggested to provide a practical negotiation channel at the private level. Also it is necessary to be active in persuading North Korea to join the international arbitration treaty in preparation for the activation of full-fledged economic exchanges. 본 연구는 남북경협의 활성화에 있어서 주요 제약요인 중 하나인 상사분쟁 해결과 관련하여 개선방안 도출하는데 그 목적이 있다. 이를 위해 남북한 간의 상사분쟁 해결관련 제도적 상황을 토대로 기업들의 남북교역 및 경제협력 거래에서의 클레임 현황과 당사자간 클레임 조항 등을 분석하여 그 문제점들을 살펴보았다. 이러한 연구결과를 통해서 몇가지 남북경협 클레임의 원인별 효율적인 개선방향 및 시사점을 파악할 수 있었다. 먼저 정부차원에서의 추진방안으로 남북간 상사중재에 관한 후속조치가 조속히 마무리 될 수 있도록 당국간 지속적인 논의를 추진해 나감과 함께 민간차원에서의 실질적 협상창구를 마련하는 투트랙 전략을 필요성을 제시하였다. 이와 함께 본격적인 경제교류의 활성화에 대한 사전준비로 북한의 국제중재협약에의 가입을 설득해 나가는 것이 필요하다. 한편, 민간기업 기업차원에서는 첫째로 분쟁해결을 위한 계약내용의 구체적 작성과 분쟁 발생에 대비해 계약조항 내 제3자 조정기능 추가의 필요성이다. 그리고 거래안정성 확보를 위해 중국 등 제3국 법인과의 공동진출 방안 모색이 요구된다.

Does Simultaneous Computed Tomography and Quantitative Computed Tomography Show Better Prescription Rate than Dual-energy X-ray Absorptiometry for Osteoporotic Hip Fracture?

고재한,임수한,이영한,양익환,감진화,박관규 대한고관절학회 2018 Hip and Pelvis Vol.30 No.4

Purpose: This study aimed to evaluate the efficacy of simultaneous computed tomography (CT) and quantitative CT (QCT) in patients with osteoporotic hip fracture (OHF) by analyzing the osteoporosis detection rate and physician prescription rate in comparison with those of conventional dual-energy X-ray absorptiometry (DXA). Materials and Methods: This study included consecutive patients older than 65 years who underwent internal fixation or hip arthroplasty for OHF between February and May 2015. The patients were assigned to either the QCT (47 patients) or DXA group (51 patients). The patients in the QCT group underwent QCT with hip CT, whereas those in the DXA group underwent DXA after surgery, before discharge, or in the outpatient clinic. In both groups, the patients received osteoporosis medication according to their QCT or DXA results. The osteoporosis evaluation rate and prescription rate were determined at discharge, postoperative (PO) day 2, PO day 6, and PO week 12 during an outpatient clinic visit. Results: The osteoporosis evaluation rate at PO week 12 was 70.6% (36 of 51 patients) in the DXA group and 100% in the QCT group (P<0.01). The prescription rates of osteoporosis medication at discharge were 70.2% and 29.4% (P<0.001) and the cumulative prescription rates at PO week 12 were 87.2% and 60.8% (P=0.003) in the QCT and DXA groups, respectively. Conclusion: Simultaneous CT and QCT significantly increased the evaluation and prescription rates in patients with OHF and may enable appropriate and consistent prescription of osteoporosis medication, which may eventually lead to patients’ medication compliance.

Cemesol混和劑가 콘크리트의 壓縮强度와 耐酸性에 미치는 影響에 關한 硏究

高在君 서울대학교 1975 서울대학교 論文集 Vol.25 No.-

This study was conducted to investigate some effects of cemesol on acid­resistance and compressive strength of concrete. In mix design of concrete, the cemesol was used as an admixture of cement, and it was added to the mix in an amount equal to 0.1%, 0.2%, 0.3%, and 0.4% by weight of cement of mix. Concrete specimens were made in accordance with the Korean Standard Specification for concrete and they were tested for acid­resistance and compressive strength at 2 weeks intervals through 8 weeks. The tests were performed in two cases such as non­curing and curing for 28 days. The results obtained from the tests are summarized as follows. 1. Refering to acid­resistance test, the cemesol was comparatively effective at every cemesol content except 0.3% in case of non­curing and it was found that cemesol content of 0.4% is most optimum. On the other hand, the cemesol was ineffective in case of curing, but it was seen that cemesol content of 0.1% is some effective at 6 weeks to 8 weeks only. 2. Refering to compressive strength test, the cemesol was remarkably effective at a content of 0.1%, but it was also shown most ineffective at content of 0.3% in case of non­curing. On the other hand, the cemesol was comparatively effective at every content of cemesol except a content of 0.2% in case of curing and it was determined that the cemesol content of 0.3% is an optimum content. 3. As results from the tests, since optimun cemesol content varied depending upon acid­resistance, compressive strength and cases such as non­curing and curing, it is desirable to choose an optimum cemesol content suitable for purposes and circumstances of construction works or conditions of location. 4. Relationship between corrosive rate and compressive strength was proportional in case of non­curing, but inversely proportional in case of curing. It was found that corrosive rate for 8 weeks does not influence compressive strength in case of non­curing but compressive strength in case of curing begins to vary under the influence of corrosion is more serious to compressive strength in case of curing than that in case of non­curing.

한국교회의 세습 문제와기독교 윤리

고재길(Jae gil Koh) 개혁주의이론실천학회 2014 개혁주의 이론과 실천 Vol.- No.7

가족주의에서 중요한 가치는 "가족에 대한 배려와 관심"이다. 문제는 가족에 대한 배려와 관심이 중요한 가치들 가운데 하나의 가치가 아니라 절대가치가 됨으로써 가족주의가 가족성원들의 각각의 도덕적 삶을 형성하는 결정적인 원인이 된다는 부분이다. 한국의 전통문화에서 가족주의는 상속제도와 연결고리를 갖고 있다. 한국의 가족주의 문화를 유지시키는데 중요한 역할을 한 물질적 이해관계는 바로 상속제도였다. 제사상소, 재산상속, 호주상속 등으로 나누어지는 상속 제도를 통해서 가족주의는 지속되었다. 가족주의는 한국의 삶의 자리에서 매우 부정적인 형태로 나타났다. 즉 정치적 영역, 경제적 영역에서 나타난 가족주의는 이기적인 가족중심주의의 부정성으로 나타났다. 놀라운 것은 이러한 가족주의의 부정성이 특별히 세습을 찬성하는 한국교회 안에서 쉽게 찾아볼 수 있다는 사실이다. 그러나 나사렛 예수에게서 가족의 범주는 하나님나라까지 확대된다. 이를 통해 이기적인 가족중심주의는 극복된다. 동일한 사건과 비슷한 결론이 다른 복음서에도 등장하고 있는 것을 볼 때 "확대된 가족의 의미"은 나사렛 예수의 삶에서 매우 중요한 가치였다 교회세습을 의도적으로 시도하는 목회자(아버지)는 그의 아들(후임 목회자)을 통해서 진정으로 "예수 그리스도에게 영광을 돌리고, 그분을 섬기면, 그분의 나라를 확장하는 것"이라고 과연 하나님 앞과 사람들 앞에서 말할 수 있을까? The important value of familism is consideration and concern over the family. But the familism becomes a decisive factor building a moral life of family members by th fact that these values of familism is denatured as an absolute ideology. In korean traditional culture the familism have something to do with hereditary system. This system have a decisive roll in sustaining the korean familism. Therefor the familism is to have negative shape in the korean life aspect; the familism appearing in the field of politics and economics has to show its egocentric negativism. Moreover it is astonishing that this negativism of the familism is to be found easily in the korean church where church hereditary is welcomed. But in Jesus Nazareth the boundary of family is extended into the Kingdom of God. So the selfish familism is conquered by this extended family.
