  • This paper presents a scheduling technique that reflects various constraints in remodeling project of inhabited condition. The remodeling project of inhabited condition is required more detailed planning and control due to claims by noise, vibration, dust, smells, limited lift capacity, and limited temporary stock area. Because of the constraints, complexity in scheduling is increased and earlier completion is required to reduce the possibility of safety and environment accidents. Especially, in case of inhabited condition, the scheduling should be linked day-time/night-time/weekend work. This paper proposes a structured scheduling technique to incorporate those constraints in remodeling of inhabited condition. This scheduling technique considers not only remodeling process but also dismantling, newly-construction, and residents movement. Process expression method using MS-Project also presented to keep connectivity with existing scheduling system.

  • This study aims to lay the foundations for domestic welfare through solving domestic problems. The major results of this study were as follows: First, there are many domestic violence facilities, but their poor financial condition and lack of human resources make it difficult to meet all need of shelter users. Second, people who use domestic violence shelters can't receive proper care and they go back to their homes in which violence still remains. It is like a vicious cycle making their situation worse and worse. Third, counseling given to abused women in shelters is arranged individually or in groups, but there are not enough programs providing proper care for them. On the basis of the realities mentioned above, this study was intended to pave the way to work out the improvement programs as follows: First, it is critical that the financial support from the government should be increased. Second, it is necessary to improve the training of personnel concerned with the handling of domestic violence cases. Third, it is important to make sure that children of abused women should be taken care of safely, and temporary jobs for the women should be secured. This will allow domestic violence shelters to serve their true purpose. Lastly, more adequate counseling services such as more instrumental 1366 phone lines, the development of various programs and the follow-up counseling should be reinforced.

  • This study considers the proper repair techniques by examining the most representative repair cases of the Korean arch bridges and proposes the constructional manual which can apply similar occasions. The cases are Seonamsa Seungseongyo and Songgwangsa Geukrockgyo where this researcher had taken part in the repair works. This Study proposes the maintenance construction manual about the performance degradation drew by performance degradation of the both Korean arch bridges in the maintenance process. First, arch bridge maintenance should be carried out in the dry season, when water is impermeable in the bottom surface of the bridge. Moreover, risk factors of the maintenance should be excluded to secure the water vally flow, the bypass and the temporary bridge. Second, prior to repair, it has to precede (1)3D shooting (2)formal examination (3)structure safety test (4)geological and lithic surveys (5)arch curvature establishment and makeshift frame settlement before transformation (6)relationship expert comments. Third, if the baduk and the foundation stones are inevitable to replace due to performance degradation on the foundation, it should use the high quality stones and secure greater stress by extending the standard range. The foundation on irregular rock needs to be flattened and underside on the replaced materials require Grengyijil to deliver the equal loads. Fourth, In the process of dismantling the stones of the arched bridge, it could make heavy weathering degree and not reuse the materials. Charge should converge the expert advices to choose the reuseable, the conservate and the alternative materials, and increase the reutilization of the raw materials by preservation and reinforcement treatments. Fifth, the side wall should be repaired by the rubble work technique which is not able to pile compost satiety, so it must use long depth of masonary stones for reinforcement. It is considered to reinforce the stone wall in shore as much as possible and protect the abutment and the side wall on the upstream for the arch bridge maintenance works.

  • As intense economic competition has led to more flexibility in the labor market, marginal or atypical employment has rapidly grown. Although marginal work represents an important proportion of whole employment, it is still characterized by insecure and unfavorable working conditions. Therefore employees in marginal jobs are highly likely to be subject to social exclusion. In turn, social exclusion puts marginal workers in a high risk of mental health problems. One of major mental health symptoms has been depression. So far, however, little attention has been paid to the effect of social exclusion of marginal employees on mental health problems including depression. Hence this study examines empirically the effect of social exclusion of casual workers in the construction industry, a protype of marginal employees, on depression. Its results indicate that social exclusion has influence upon depression of marginal workers. This study is the first one to delve into the relationships between temporary employment, social exclusion, and depression of marginal employees. Yet much more empirical researches are needed in order to shed brighter light on these relationships.

  • This work examines reemployment processes through the use of event history unemployment data in the United States. Two aspects of these processes, the duration of unemployment and changes in the reemployment rate, are modelled and analyzed in terms of individual characteristics and their structural positions in the labor market. The secondary labor market is a competitive market in which unemployment occurs because people quit their jobs to devote more time in search for better jobs. Using search theory, the rate of reemployment has a positive time dependence as the searcher lower her reservation wage with the passage of time. By contrast, the primary market is characterized by long-term employment relations which reduce voluntary turnovers but generate layoffs temporarily. Relying on contract theory, because workers on temporary layoffs wait for recall, reemployment rates have a constant time dependence. Empirical results of unemployment durations indicate that reemployment processes are influenced by individual's positions in dual labor market structures. While the analysis suggests that the amount of search reemployment seems to be positively related to the degree of competitiveness of a market, somewhat weaker results are noted in the search reemployment processes in competitive markets.

  • As augmented reality (AR) technology has been utilized to enhance the user experience, several AR applications have been developed in the cultural heritage domain. Although there has been significant progress in this area, naive augmentation representation becomes an obstacle to provide an enhanced user experience and there has been little research on an effective AR experience methodology that reflects the characteristics of AR technology. Furthermore, the development of temporary content that comes from the absence of the authoring framework restrains the content ecosystem, which is an essential requisite for sustainable service. To resolve these issues, we propose a space-driven AR experience methodology, Spacetelling, to extend established object-oriented augmentation trends and Storyscape that generates spatio-temporal related contents for the spacetelling and supports sustainable service. Moreover, we present the wrap-up system framework covering both features mentioned above for the archeological site tour. Finally, we present our work-in-progress project, K-Culture Time Machine Project, to investigate the practical feasibility of our proposals. Through these proposals, we expect that sustainable AR applications with improved user experience will be possible in the cultural heritage domain.

  • In this study, we select a site adopting real composite precast concrete method. Estimating real construction cost and imaginary cost appling reinforced concrete method in the site, we compare the costs. Through using high intensity concrete and prestressed concrete, amount of concrete is reduced more than 50% but there isn't big gap in material cost. In the main construction cost of composite precast concrete method, the material cost with production cost and transportation cost are in that, joints and topping concrete are account for 90%. But in case of reinforced concrete, labor cost spent at concrete steel bar and form is account for 30%. In the cost of attached, compared with composite precast concrete method, the reinforced concrete method taken in big portion by temporary work and scaffolding is twice as much as composite precast concrete method in construction cost. Therefore, economic efficiency is excellent reducing 11% total cost of composite precast concrete method from the reinforced concrete method.

  • Objectives: We aimed to find the relationships between employment status and hs-CRP level among Korean wage workers using the 2016 Korean National Health and Nutrition Examination (KNHANE, revised). Methods: This study was conducted on 1,937 daytime wage workers over the age of 19 and within a normal weight range (18.5≤BMI≺25). Regular workers were defined as those granted an employment guarantee until reaching retirement age, and non-regular workers were defined as temporary, non-typical, dispatched, short-term workers and contractors. For hs-CRP, three divisions were classified as recommended by the Centers for Disease Control and Prevention (CDC) and American Heart Association (AHA) with less than 1.0 mg/L indicating low risk of cardiovascular disease, above 1.0 mg/L and below 3.0 mg/L considered moderate risk, and more than 3.0 mg/L indicating high risk. To find the relationship between work type and hs-CRP level in Korean wage workers, multinominal logistic regression analysis was performed. Results: For non-regular workers, the odds ratio of the cardiovascular moderate-risk group and cardiovascular high-risk group was statistically significant compared to regular workers. After adjusting for factors such as gender, age, subjective health status, income, education, smoking, and physical labor, the odds ratio of the cardiovascular high-risk group was statistically significant. Conclusions: In this study, the relationship between non-regular workers and high hs-CRP level was examined. Based on this, institutional strategies should be pursued to prevent and manage cardiovascular disease among non-regular workers.

  • In "A Good Man Is Hard to Find," Flannery O'Connor describes a striking journey of a family, in which all the members dramatically get killed. Through the tragic death of Bailey's family, O'Connor evokes the reader to think about life and the life after death. Growing up in the communities of Catholicism and Protestantism, O'Connor herself had agonized with the same question between the two types of Christian belief throughout her life. In the story, O'Connor embodies her anguish with the major characters and questions the reader about the meaning of Christian salvation. More specifically, Bailey's family represent the people who get lost in life. They live without any direction and purpose. Red Sammy and his wife, on the other hand, provide travellers with rest, food, and the necessaries. The Tower is a shelter of travellers in life; however, it is not everlasting but temporary. The Misfit, exemplifying religious stragglers, has been completely frustrated with the variance of Christian salvation theories, and no longer practices the religion but knows enough to justify his cruel behaviors. Finally, the grandmother is the manipulator and opportunist of the religion. All those characters are fragments of human characters and their life - obscene and transitory. In the story, there is little God's grace on the surface even though the writer claims "all my stories are about the action of grace." Nonetheless, the reader should be able to identify with those characters because they are the mirror images of themselves. While visualizing the characters, O'Connor wants the reader to have a moment to think about the "Righteousness," and ultimately to seek out God's grace that she essentially wishes to show the reader. Instead of showing God's grace directly, O'Connor ultimately leads the reader to consider about God and the grace as she/he reads the work.

  • The whole world was confused, unintended "COVID-19". It has become a constant phenomenon, not a temporary one, and people are getting used to this era. Among them, We are combating the form of "the film" which is playing a role of a multiplex in Korean film industry. Now we have studied the development of the future korean industry based on the movie theater form through our cultural industry, New platform OTT. As a result for the research, the OTT platform, which is located in one genre today, should be regarded as an opportunity to develop films, and the movie theater, which is a part of the development of the film industry, differs from the OTT platform. with "memory of space", the result was that "The audience's footsteps can move again." The crisis of "COVID-19" should bring about the consequences of turning into opportunity.
