With the rapid development in the economy and other fields as well, the standard of living in South Korea has been improved, and consequently, the demand of automobiles has quickly increased. It leads to various traffic issues such as traffic congestion, traffic accident, and parking problem. In particular, this illegal parking caused by the increase in the number of automobiles has been considered one of the main reasons to bring about traffic congestion as intensifying any dispute between neighbors in relation to a parking space, which has been also coming to the fore as a social issue. Therefore, this study looked into Daejeon Metropolitan City, the city that is understood to have the highest automobile sharing rate in South Korea but with relatively few cases of illegal parking crackdowns. In order to investigate the theoretical problems of the illegal parking, this study conducted a decision-making tree model-based Exhaustive CHAID analysis to figure out not only what makes drivers park illegally when they try to park vehicles but also those factors that would tempt the drivers into the illegal parking. The study, then, comes up with solutions to the problem. According to the analysis, in terms of the influential factors that encourage the drivers to park at some illegal areas, it was learned that these factors, the distance, a driver's experience of getting caught, the occupation and the use time in order, have an effect on the drivers' deciding to park illegally. After working on the prediction model, four nodes were finally extracted. Given the analysis result, as a solution to the illegal parking, it is necessary to establish public parking lots additionally and first secure the parking space for the vehicles used for living and working, and to activate the campaign for enhancing illegal parking crackdown and encouraging civic consciousness.

The purpose of this study is to investigate the effect of gardening programs using vertical gardens on helplessness, depression, and self-esteem in patients with chronic mental disorders. This study was applied to 21 patients with chronic mental disorder who were admitted to the rehabilitation hospital of E Hospital in Seoul from June to October 2018. The group was treated as an experimental group (N = 21) 5 times a week. For 20 weeks, each session lasted 30 minutes. Patients in the experimental group programmed 4 sessions of general occupational therapy, which combined treatments to improve cognition and training, and 1 session of a horticultural program using a vertical garden. Helplessness, depression, and self-esteem were evaluated for pre and post evaluation of the horticultural program. After completing the program, the average score of helplessness in the experimental group decreased by 0.91 points from 47.38 to 46.47, and there was a statistically significant change (p=0.043). The mean score of depression in the experimental group was 9.23 before and after 9.08, which was statistically significant (p = 0.035). The average score of self-esteem in the experimental group increased by 3.14 points from 27.99 to 31.13 at a statistically significant level (p = 0.001). This result suggests that a gardening program using vertical gardens has an effect on helplessness, depression, and self-esteem in patients with chronic mental disorders. And this means that long-term plans and effective programs for recovery from chronic mental disorders to the community are needed. With a horticultural work program using a vertical garden, the helplessness of the mentally impaired in a closed treatment space is restored, and such treatment space needs to be increased.

Prior studies have shown positive effects of outdoor activities on the elderly's physical, mental and social health. 'Active aging' and 'age-friendly' neighborhood can be created by modifying the experiences and perceptions of the outdoor environment. This study aims to investigate the outdoor activities of the elderly living in a low-income elderly concentrated area and their perception of the neighborhood environment. We also explored the context of interactions between the facilitators and inhibitors of outdoor activities on the basis of temporal, spatial, and social conditions. We used a mixed method approach by collecting two different types of qualitative GIS data : observation maps of the main places and individual cognitive maps with in-depth interviews. The observational map analysis indicated that the preferred places and activity patterns differ by age, gender, and size of the group. The cognitive map and interviews demonstrated that the elderly's activity goals and perception of the landscape differ by places such as forests, parks, streams, open-spaces, vegetable gardens, and alleys. The elderly's desire for outdoor activities can be better fulfilled when their front doors and alleys are well-connected to an open-sight pleasant space. Familiarity is an important factor for the elderly, therefore it is important to remove the psychological and physical barriers by increasing the legibility and accessibility of places. In addition, social interactions and conflicts can have a significant influence on the elderly's occupation of space in the neighborhood environment.

This paper aims to identify the key features of the novel writing of Korean American immigrants and their meaning as one aspect of movement and contact occuring in the early modern period. The late return of the novels written by Nakcheong THUN in the 1930s is significant in that it restored ideas on the diversity of early modern mobility and confronted the history and culture of immigrants who were excluded from records and memories. Not only are these novels a product of the phenomenon of immigration, but they have also created a crack in the dichotomous perceptions of domination and subordination, center and periphery by envisioning it as a space that creates new history, culture, institutions and values. These novels treat the free love of intellectual, emotional, and ethical figures as a central event, demystifying Western free love, and at the same time, a society divided by various identities including class, race, and gender. The novels by Nakchung THUN visualize the active exchange between the immigrant and the indigenous community through the character of Jack, and imagines the heterotopia as a place where not for the immigrants' utopia, but for everyone's coexists. These novels have declared a kind of memory war on the subordinate and marginalized contact zones. The contact zones of the immigration area had been a place for experiencing extreme conflicts and discords, and at the same time, it has served as a place where various groups and communities are connected. The contact zones were common areas of solidarity and creation before being subject to division and occupation. The contact zones are far from the border or borderlands, so it is not a fixed and immutable deadlock. As a world free from central domination the contact zones have been a space that preoccupied history and culture through various encounters, and have been a community.

In cable tunnel construction using TBM, the vertical shaft is an essential structure for entrance and exit of TBM equipment and power lines. Since a shaft penetrates the ground vertically, it often encounters rock mass. Blasting or rock splitting methods, which are mainly used to the rock excavation, cause public complaints due to the noise, vibration and road occupation. Therefore, mechanical excavation using vertical shaft excavation machine are considered as an alternative to the conventional methods. However, at the current level of technology, the vertical excavation machine has limitation in its performance when applied for high strength rock with a compressive strength of more than 120 MPa. In this study, the potential utilization of waterjet technology as an excavation assistance method was investigated to improve mechanical excavation performance in the hard rock formations. Rock cutting experiments were conducted to verify the cutting performance of the abrasive waterjet. Based on the experimental result, it was found that ensuring excavation performance with respect to changing in ground conditions can be achieved by adjusting waterjet parameters such as standoff distance, traverse speed and water pressure. In addition, based on the relationship between excavation performance, uniaxial compressive strength and RQD, it was suggested that excavation performance could be improved by artificially creating joints using the abrasive waterjet. It is expected that these research results can be utilized as fundamental data for the introduction of vertical shaft excavation machines in the future.

Differences in community space of weed and rice were investigated among five types of rice (Oryza sativa L.) cultivation. The five types employed were three transplanting cultivations such as conventional hand transplanting, machine transplanting with 30-day-old seedling, and machine transplanting with 10-day-old seedling and two direct-seedlings such as flood direct-seeded rice by pregerminated seed and dry direct-seeded rice by dry seed. The greatest competition between rice and weeds as determined by growth rate of rice was found in between 10 and 11 weeks after transplanting (WAT) and/or seeding, irrespective of cultivation types. Competition injury due to weeds was greater in transplanting with 10-day-old seedling than with 30-day-old seedling. The greatest injury in growth of rice was found in direct-seeded cultivation. In transplanting cultivations space occupation by rice in lower than 80 cm height level was low as compared with that by weeds. Plant heights of dominant weeds such as E. crus-galli and E. kuroguwai were shorter by heading date, but taller after the heading date than those of rice. In direct-seeding community space was mainly occupied by the weeds. The pattern of community structure and competition injury caused by weeds showed a similar tendency obtained on the basis of species distribution, number, and dry weight of the occurred weeds.

The cultural pluralism on which more and more emphasis is put in the globalized cultural environment, takes local identity as a crucial index for the cultural exchange on the global level, but at the same time it results in transforming individual regions/places into a homogeneous space, as it forces the local identity itself to fit into the standardized global perspective. In this context I focus on two art projects that are related to 'Dongducheon', a town that houses the U. S. Second Infantry Division. These projects attract specific attention due to the fact that Dongducheon is a significant place with very 'thick' cultural identity: it reveals that modernization in Korea took place in intersection of nationalism, patriarchy and gender/sexuality postcolonial (military) culture. With these two Dongducheon related art projects (Donglyung Kim) and (Eunyoung Jeong) as excellent examples of site-specific art practice, this paper asks what it means to keep the historicity of disappearing local space/place in the global era. And how is it possible to 'represent' an extremely gendered/sexualized place like Dongducheon. This should be examined from a postcolonial feminist perspective. Since emancipation from Japanese occupation Dongducheon has been an island or an outside space in the nation-state Korea. This becomes more complicated, as now mostly women from the Philippines or former Soviet countries are working in the nightclubs in Doungducheon. and are feminist activist experiments to make the place with its residents to be seen and heard in proper a way of mourning, recognition and communication. shows the 'new' kijich'on women as those who are daring to be on an 'Odyssey' for a better life as they run everyday life in Dongducheon, working in clubs, doing laundry, bearing children, going to mass; tries to help them to be heard and felt, while it gathers sounds on the street or at mass and shows the doors or narrow alleys which lead to the their rooms. It aims to mourn the dead kijich'on women and to represent the precarious life of the present migrant kijich'on women, as it shows no faces.

Quality of the library service, because it is based on the subjective meaning of the user for a particular service, depending on the individual expectation level, can be divided between satisfaction and dissatisfaction. Therefore, library services that are performed in public libraries also ultimately assessment of library services may influence based on the expected value of the user. This study is a satisfaction survey of library services to the public library of Goyang. Overall satisfaction of Public Library of Goyang in this study are in the following orders: 1) facility, 2) cultural programs and courses, 3) librarian kindness, 4) collections. To understand the specific meaning of each preference, it was analyzed in the followings: 1) the expectation level to the library space, 2) expectation level to librarians, 3) new service the users desire, 4) service the users want, etc. by age and occupation. As the age of the user increases, the demand for traditional library usage increased. In addition, services that utilize the same library external resources and utilization of external lecturer is like finding employment and art courses, expectation level of users such as reading course to utilize library resources was the highest.

Each participant in building construction project requires their own workspace to execute their activities. In this environment, inappropriate workspace planning in construction site causes workspace conflicts which result in a loss of productivity, safety hazard and poor-quality issues. Therefore, workspace should be regarded as one of the most important resources and constraints have to be managed at construction site. However, current construction planning techniques such as Gantt chart, network diagram and critical path method have proven to be insufficient to workspace planning. This paper contains formalized process for workspace planning in 4D BIM environment to prevent workspace related problems in construction project. The proposed process in this paper represents workspace occupation status for each activity and suitable solutions for identified workspace conflicts by integrating workspace attributes and activity execution plan. Based on the result of this study, project manager will be able to prevent probable workspace conflicts and negative effect on project performance by devising appropriate workspace plan during preconstruction phase.

A tendency to ignore the existence of public space in Korea under the Japanese colonial period seems to be driven from nationalist historiography in which all historical events under the colonial power have to be interpreted in terms of militant controls and resistances against them. Historical approach to mass media of that period has lasted to be saturated with the tendency and forced history students to stick to the nationalist guidelines. Struggles against Japanese imperial power by national-capital-operated newspaper have been a main menu of studies on the period's communication. The media were often hailed as fighting the colonial power for nation's independence. The present thesis aims to criticize the nationalist point of view and to reveal that nationalist interpretations may miss a variety of historical information. Even under the severe surveillance of colonial police some journalists tried either to inform officially or to smuggle into informed groups. The colonized society could experienced fields of public-ness throughout the practices of such as media fields, cultural fields, political fields. Those fields, of course, didn't come from the graceful favor of the colonial power but from the construction of the colonized. The public-ness seemed to be born for the easiness of control, but became later a constructed field of public-ness with which the colonized semiotically wrestled the power and grew a modern type of political (un)consciousness. Depicting what happened just before 815 liberation day in Korea the present paper showed that the less nationalist historiography can render help to those seeking political practices of the colonized in a micro-level.
