A climbing lane is installed to separate low-speed traffic from high-speed traffic if drastic traffic capacity reduction is expected due to a large number of vehicles that slow down in the upward section. Existing studies on climbing lanes have focused on the designation, location of starting and ending points, and installation method of climbing lane with regard to road design standards. However, in terms of traffic operation, it was known that the climbing lanes cause traffic congestion due to the increase of traffic volumes. In this regard, this study aims to establish traffic operational guidance as to how much effects temporary closure of climbing lanes can have on traffic improvement according to the volume-capacity ratio, grade, and composition of trucks. A test section of simulated climbing lane was selected in Nakdong JC bound for Masan(136.9K~133.3K, 3.6km, 3.7%) on Jungbunaeryuk expressway to conduct VISSIM analyses, microscopic traffic simulation based on such control variables as traffic volume(v/c), grade and the trucks ratio. As a result of the analyses, it has been found that v/c and the ratio of trucks are the key variables for efficient traffic management of climbing lanes in order to relieve traffic congestion via climbing lane. If ratio of trucks are more than 50% and when v/c would be 0.8, both climbing lane would be closed and non-operated regardless of grade and ratio of trucks when v/c is 1.0. With the increased traffic due to a five-day work week system, continued peak hours during the weekday, increased and various patterns of congestion on expressway, this study would be expected to contribute to facilitating researches on flexible operational standards for road facilities.

With the COVID-19 pandemic, the global economy has stagnated and our daily lives have changed. The rural economy is also experiencing damage, such as an average of 65% or more decrease in the number of visitors to rural experience resort villages due to the spread of COVID-19. In order to minimize the damage arising from the prolonged coronavirus, a hospitality system in response to changes in rural tourism behavior and consumer demand is needed to revitalize rural areas and maintain continuous economic independence. Therefore, this study attempted to find ways to utilize landscape resources such as education, culture, history, and ecology in order to complement the existing experience programs in connection with local resources and local environment. Wibong Village, which is the subject of the study, attempted to revitalize the village using the resources through the "Creative village creation" project in 2015. Due to poor management of historical resources, difficulty in operating experience programs, and response to changes in the natural environment, the rate of implementation of the project plan was very low. Currently, the demand for experience is also decreasing due to the COVID-19 effect, so it was judged that it was necessary to develop an experience village program suitable for the needs of experienced visitors by discovering additional local resources for the continuous operation of the experience village. In order to solve the problem of the use of landscape resources and the spatial composition of the study site, additional investigations of local resources were made, and an experience program course that could be operated by theme was proposed by configuring a space suitable for the use of landscape resources. By dividing the additionally investigated landscape resources into history, ecology, and region, an experiential course was created to separate the traffic lines, and the space composition for large-scale experienced visitors that had been previously operated was constructed in a form suitable for the post-corona era. In addition, at least two experiential tour courses that can be operated by period were proposed to maintain economic effects. Starting with this study, if further research on the creation and spatial composition of a rural experience village centered on the connection with the region, it will be used as research results that can be referenced in projects such as village creation, rural space planning, and living area analysis. It is expected that it will be able to effectively cope with the construction of a rural area suitable for the post-corona era, where demand is expected to increase in the future.

Objectives: This research is part of a study to be conducted over five years starting from 2017 by the Ministry of Environment on the development of technologies to evaluate the impact of chemical accidents on the human body. Methods: For this research, a five-stage specific study method was developed. Results: In brief, the developed health risk assessment method can be summarized as follows. First, a health risk assessment system was built based on the guidelines set forth by the USA NRC/NAS. Second, based on the disease manifestation theory, the health risk assessment method was divided into 1) a carcinogenic health risk assessment method focused on all carcinogens except non-genotoxic carcinogens and 2) a non-carcinogenic health risk assessment method focused on noncarcinogens including non-genotoxic carcinogens. Third, the detailed contents of the health risk assessment method were developed in four stages(hazard identification, dose-response assessment, exposure assessment, and risk determination) through theoretical consideration of the assessment of the level of health risk related to chemical exposure. Finally, a health risk assessment methodology, classified into stages to address acute, subacute/subchronic, and chronic conditions was developed after considering the physicochemical behavior of hazardous chemicals upon implementation of countermeasures after a chemical accident. Conclusions: A method to evaluate the health risks related to toxic chemicals generated by chemical accidents was developed. This study was performed with the purpose of developing a mathematical health risk assessment method to evaluate the health effects of exposure to hazardous chemicals upon implementation of emergency countermeasures after chemical accidents.

Korea Utility Helicopter(KUH) is a project to replace the aging helicopter presently being operated by the military with a domestic helicopter. The auxiliary power unit is a device that supplies emergency power to the system by an alternator installed when the main generator fails and the start motor converts the electrical energy of the battery into mechanical rotational energy to rotate the auxiliary power unit engine. With continuing power and operation, defects of the starting motor were found and improvements were carried out to solve it. In the failure mode analysis, the causes of possible defects were classified into 5 categories. Analysis of the 5 factors revealed that the main cause of defects is mechanical wear, which was found to be related to spring pressure. 250 tests were conducted through the theoretically determined pressure and regression analysis was performed with 4 sampling.The results showed that pressure was related to wear rate. In conclusion, early wear and breakage due to wear can be controlled through spring force and test showed the prediction of wear and the validity of the result were confirmed.

On January 16 to May 31, 2012, Korea Expressway Corporation was carried out an pilot overweight enforcement using high-speed weigh-in-motion at Gyeongbu expressway 195.0k (Gimcheon) and Jungbunaeryuk expressway 119.5k (Seonsan). In this study, it is attempted to analyze the practical effect of high-speed weigh-in-motion by comparing the average total weight and traffic volume of eight weeks before and after the these overweight enforcement, respectively. The main results are as follows: First, the result of analysis of the change in average total weight and traffic volume, it was found that it did not differ after as in previous traffic volume, and the total weight is reduced. This means that the total weight is not reduced by decreasing freight traffic, but by decreasing the total weight. Therefore, it can be seen that there is an effect of pilot overweight enforcement using high-speed weigh-in-motion. Second, the average total weight and total weekly traffic volume decreased rapidly starting from the start of the overweight enforcement, but there was showing a tendency to increase gradually again.

This paper is focused on objective and meaning of its compilation through reviewing system, composition, method of description, and content of "Jwagyebudam". "Jwagyebudam" has all round form of a history and character book by recording via arranging figures from the end of 16th century to the middle of 18th century in a chronological order. Figure were not only assigned at close range by steretyping people into groups to a degree in it, but also recorded in a chronological order. In view of method of description, "Jwagyebudam" concentrated a theme by recording via separating different people associated from a figure and content of the same event by using the same method like 'Hogeonbeom(互見法)' shown in "Sagiyeoljeon(史記列傳)". In addition, it obtained effect to objectify evaluation of figures included. In a method of embodying figures, it has described concretely and in a three dimensions figures by recording anecdotes and poems associated with them via focusing on lifelong characteristic aspect of corresponding figures. In other words, "Jwagyebudam" can be called by biographies or character books, writings specialized in characters center among writings of method to weave freely experience. In a broad sense, it can be called a writing to cover a function of history book, poem and picture. This was located to a starting point of variation of inclusive and descriptive method. Namely, several kinds of writings in late Joseon dynasty can show aspect to fulfill specialized aspect gradually.

In Korea, historical plays took an epoch-making turn from the previous historical plays in terms of approaches to topic and material and methods of rewriting history in the 1990s. Historical plays became dehistoricized with individual, everyday life, and faction emerging as major codes of historical plays according to mistrust in history and grand narrative as the original and disappearance of trust in the growth and totality of history. A new trend became dominant of presenting fictionality prominent instead of reproduction of history and freely playing with history outside the context. While modern historical plays were subject to the content of history, post-modern historical plays sought after new history writing to tell a new story on history within a framework of fiction. Focusing on some of the trends in post-modern historical plays since the 1990s, which include play with history, daily life-style history writing, and reproduction patterns of colonial modernity, this study examined the goals, representations, and text strategies of new history writing in three historical plays, Generation After Generation(2000) by Park Geunhyung, The Mercenaries(2000) by Park Sujin, and Chosun Detective Hong Yunshik(2007) by Sung Giwoong. In Generation After Generation, the author adopts a plot of starting with the present and tracing back to the past, breaking down the myth of racially homogeneous nation. At the same time, he discloses that the colonial history is not just by the oppressive force of Japan but also by the voluntary cooperation of Korean people. That is, we are also accountable for the colonial history of the nation. The Mercenaries contrasts the independence movement during the colonial period against the modern history developed after Liberation, thus highlighting the still continuing coloniality, namely post-colonial present. The past is presented as the "phantom of history" making its appearance according to the request of the present hoping for salvation. The author politicizes history and grants political wishes to history by summoning the history by personal memories such as fictional diaries and letters with Messiah-like images opposed to the present of collapse and catastrophe. In Chosun Detective Hong Yunshik, the author makes an attempt at the microscopic reproduction of daily life by approaching the 1930s as the modern period when capitalist daily life started to take root. The lists of signs comprising daily life in colonial Gyeongseong are divided between civilization and savagery and between modern and premodern. With the progress of narrative, however, they become mixed together and reversed in the representation system in which the latter overwhelms the former.

The purpose of this study is to examine the main features of South Korea's New Northern Policy and to make some suggestions for cooperation with neighboring countries' initiatives. The New Northern Policy encompasses the whole of Eurasia, but the starting development area would be the border region of the Korean Peninsula. In this viewpoint, this study examines the Belt and Road Initiative of China, the New Eastern Policy of Russia and the Steppe Road Initiative of Mongolia, and presents the characteristics, problems and some implementation strategies of the New Northern Policy. Apart from the future possibilities of the regional cooperations that include North Korea, it would be necessary for South Korea to secure and expand the possible opportunities for "Korea-China-Mongolia-Russia" cooperation. In order to create a close cooperative environment with North Korea in the future, it would also be necessary to build a maritime route, with port development around major border regions on the Korean Peninsula, including Russia, and to develop the port-railway intermodal transportation system with neighboring countries. South Korea need to actively cooperate with neighboring countries to develop the new Eurasia logistics routes would be more favorable to the Korean Peninsula in preparation for the time when the North Korean nuclear issue will be resolved.
