This paper deals with simplified structural analysis of single- and double-span rigid frame types of reinforced concrete bridges. A number of equations are proposed to compute the moments due to the live load, dead load, and earth pressure of rigid portal frame type bridges. By using a finite element program coded in this study, 479 highway bridges having different height, span length, and span ratios are analyzed. On the basis of the results of structural analysis, the equations to compute moments of rigid frame type bridges are derived based on the multi linear regression analysis. All the values of correlation factors obtained in this study are over 0.998 and the results obtained by the proposed equations generally show an excellent correlation with the results of finite element analysis. The proposed equations can be directly used to compute the moments of rigid frame type of bridges, if simplified analysis of highway bridge is necessary.

일본의 靑島 經略과 靑島 도시경제의 발전, 1914-1922

김형열(Kim Hyongyol) 도시사학회 2009 도시연구 Vol.2 No.-

Japan has long harbored imperialist ambitions about Chinese territory (especially Shandong), so Japanese thought that the outbreak of World War I was the best opportunity to overcome Japanese domestic/ international crisis. Under the cloak of duties of “Anglo-Japanese Alliance”, Japan immediately declared war against Germany. On November 1914, Japan finally occupied Qingdao, and governed it by Japanese military. Therefore, Qingdao experienced “changes”. Those are main agents of Imperialist colonialist changes and characters and functions of city’s changes. The economy of Qingdao had serious economic losses by the outbreak of World War I and German-Japanese War. There were decreases of trades and destructions of city. Furthermore, Chinese people had campaigned against “Japanese materials” because they were outraged by “Japanese 21-demands to China”, that brought economic contraction of Qingdao more and more. Many Japanese in Qingdao were fell into ruin after that, the total amount of trade had decreased considerably. Because Qingdao’s city economy was dependent upon the income from Japan. But, investment to China by Japan didn’t simply entrust to ordinary people. That means, Japanese government enterprise or national industrial capitals took the lead in the Chinese market. Japan not only exported Japanese goods to China, but also produced Japanese things in China. Japanese materials produced in China were sold in China and another countries. This strategy gave Japan an advantage over the colony competition between other Imperial Power. Japan started to build systemic infrastructure, to invest capitals, and to develop industrial estates in Qingdao. As a result, large sum of Japanese money was invested in Qingdao, lots of individual /partnership companies were built in Qingdao. A wind of change was blowing through Qingdao. Especially textile industry, mill industry, and match manufacturing possessed unrivaled technological prowess. Qingdao couldn’t completely be converted to industrial city in the Period of Japanese Occupancy, but showed the process of switching over to a modernized industrial city. After that, Qingdao has steadily achieved industrial growth through the policies and maintenance systems those were established at Japanese colonial era, even after the reversion of Qingdao to China.

The “Sea Defense” policy taken by the Qing dynasty shows China’s perception of the world at that time, regardless of its military strategy. Despite his excellent scientific technique on various fields of the country, he eventually fell into a well-worn frog due largely to the lack of a national-level strategy to actively respond to the outside world. Of course, it is true that the fact that China has never experienced a large-scale invasion from the sea or that the threat of the frontier has always started in the north has lowered the level of the sea defense and made it a strategic military system centered on land power. However, the fact that China, which had the largest battleship in the world until the Ming dynasty, still possessed naval power at the level of the Middle Ages when the Opium War broke out, and that he tried to maintain the system of the heavenly dynasty of China until the second Opium war could indicate that chinese intellectuals at that time still had a serious problem on their perception of outside world. Moreover, like the overlapping and confusion shown by fulfilling chinese westernized reform whose aim was consolidating the governance structure of the Qing Dynasty, the conditions of selecting the naval base in the Qing Dynasty indicated the closed and shortsighted nature of chinese westernized reform. In this paper, we will look at what changes took place in the sea defense policy after the First Opium War, focusing on the Shandong region, and then on how the construction of sea defense led by Li Hong-zhang during the chinese westernized reform. In addition, we will figure out how Germany, which wanted to build a colony with a naval base in East Asia, approached China through their maritime policies and explore how the process of colonizing the Kyoju Bay by Germany has progressed.

인식상대주의 관점에서 위기관리에 대한 방법론

김형열(Hyung Yul Kim) 위기관리 이론과 실천 2005 Crisisonomy Vol.1 No.1

이 논문은 인식상대주의 관점에서 위기를 효과적으로 관리할 수 있는 접근법을 모색하는 데 그 목적이 있다. 국가의 기본임무가 국민의 생명과 재산을 보호하는 것이라면, 국가안전이 전제되지 않고는 국민의 자유가 보장될 수 없다. 이러한 의미에서 위기관리는 국정운영의 최우선적 과제가 되며, 정책패러다임에 기본전제가 된다. 위기는 예방ㆍ준비ㆍ처리과정으로 관리될 수 있는데, 위기의 특성상 각 과정이 분리되어 취급되기보다는 상호연계된 관점에서 총체적으로 접근할 필요가 있다. 이 논문에서 필자는 위기관리에 대한 여러 가지 접근법을 검토하면서 인식상대주의에 바탕을 두고 체계적 접근법과 상황적 접근법을 중심으로 위기문제에 대한 해결방안을 논의하고 있다. 국가운영의 총체적인 관점에서 위기관리는 효율성 제고를 위해 정책과정의 일환으로 취급될 필요가 있다. 이를 위해 필자는 구조적ㆍ절차적ㆍ관리적ㆍ행태적ㆍ정치적ㆍ사회적ㆍ체계적ㆍ비교적ㆍ직관적ㆍ접근법을 제시하였다. 이들은 각각 그 유용성과 한계성이 있기 때문에 이들의 유용성을 수용하여 상승효과를 달성한다는 관점에서 상황적 접근법의 효과성을 논의하 였다. 이 논문에서 제시된 상황적 접근법은 체계적 접근법을 기본으로 하여 다른 접근법을 가미시켜 활용하는 것이다. This paper aims at searching an effective approach for emergency management in terms of cognitive relativism. As the main goal of a nation is to protect the lives and properties of the people, the national security must be maintained for preserving their freedom. In this sense, emergency management is the top priority in state governance and prerequisite of policy paradigm. Emergency can be managed in terms of three stages: prevention, preparedness and treatment. In this paper, the writer reviews various approaches for emergency management and focuses on the systems and situational approaches in terms of cognitive relativism. For the whole viewpoint of state governance, emergency management needs to be dealt with as a part of policy process. For this purpose, the writer suggests the structural, procedural, managerial, behavioral, political, social, systems, comparative, and intuitive approaches. Since each approach has its merits and limitations, the writer discusses the usefulness of the situational approach which is to utilize strengths of each approach for synergistic effect. The situational approach in the paper implies that the systems approach is fundamentally relied upon along with partial use of other approaches.

신문화운동기 리다자오(李大釗)의 조화사상과 정치인식

In a word, Li Da-zhao's idea of harmony is a harmonious view of the world and a view of life, in which two phenomena and values, which are mutually contradictory and conflicting, can be of one accord and be coexisting. Li Da-zhao saw that everything in the universe is rotating. He thought that prosperity and decline, life and death, destruction and creation, health and decay, old and young, and birth and death both of which were necessary and inevitable were repeated, and in the end, were different appearances of the same things. What should have created new China, new ideas and new institutions should have been practically young, new, dynamic, and energetic society, not just seemingly new and young society. Li Da-zhao's constructive, practical view of the universe and view of the world served to induce the political awakening and artificial efforts of intellectuals to create a new China. By doing so, the people have been forced to demand democracy as a substitute for monarchism and to wipe out the despotism, an element of the old tradition of china that has hindered the revival of young China. Such a conflicting and coexisting, contradictory and changeable view of the world, which is known as the “Youth” universe view, was, in other words, harmonious ideas. This idea of harmony was revealed in several writings published by Li Da-zhao in New Culture Movement era to shape his political and social theory, and later determined the character of political campaign he sought to overcome the political and social contradictions. In Li Da-zhao's whole system of thought, it is too difficult to dismiss the ideological influence so that we can’t look his idea of harmony as an immature philosophical theory or a bourgeois deviation before he became a Marxist. The concept of youth, which was very important in his ideas and writings, could not only mean the ideal future that the old and sick China had to pulled out of the current situation and wanted to achieve. It was another character and appearance china already had at that time. Li Da-zhao did not only want to give the Chinese at the time the ideal value of regeneration and rebirth, but to find the principles and power to create youth china, or new china, in a real society. This idea of harmony between confrontation and coexistence could develop into a trend to accept the matter along with the spirit as a key element in operation of universe from the phase of emphasis on non-materialistic factors. Then, the spiritualism that Li Da-zhao showed in embracing Marxism, in other words, would be an evidence that he has been embraced materialism in a system of idealistic thought.
