  • In dieser vorliegenden Arbeit wird die eigentliche Bedeutung des Hauses in bezug auf M. Heidegger, G. Bachelard und O. F. Bollnow analysiert. Bei Heidegger ist das Wohnen ein Wesensmerkmal des Menschen und das Haus ein Raum des Wohnens als das Pflegen und Schonen. Insbesondre Bachelard hat die schuetzend Funktion des Hauses und das Haus als das Glueck des Wohnens behauptet. Fuer Bollnow bedeutet das Haus eine Mitte des menschlichen Lebens und der Welt. Heidegger behauptet, dass wir so in der eigentlichen Not des Wohnens, d.h. in der Heimatlosigkieit sind. Wir muessen nach die Bedeutung des Hauses nicht als einen wirtschaftlichen Wert sondern als den eigentlichen Wohnraum denken und das Wohnen lernen. Bachelard weist darauf hin, dass das Haus als ein gluekliche Raum ein wesentliches Trauen voraussetzt. Und er versteht das Haus mit dem dialektischen Zusammenhang zwischen dem Haus und der Welt. Bollnow versucht ueber dem Raum in anthropologische Hinsicht zu betrachten. Er behauptet, dass der Mensch seine wesentlichen Bedeutung durch das Wohnen hat. Durch die Vermenschlichung des Raumes muss der Mensch die Verantwortlichkeit ueber den Raum uebernehmen. In der heutigen Gesellschaft bemessen das Haus sich nur mit einem wirtschaftlichen Wert. Wir muessen das Haus lesen, und die eigentliche Bedeutung des Hauses.

  • The term 'fourth industrial revolution' was mentioned at the World Economic Forum (WEF) in 2016 and has become a term representing a new industrial era based on information and communication technology (ICT). In the environment of the 4th industrial revolution, ESG management activities are becoming a very important factor in business activities. With the emergence of a new paradigm of organizational operation in the post Covid19 era, the demands for ESG (Environment, Social, Governance) investment related to the environment, social responsibility are increasing. This study examines the role that can support ESG management by utilizing the expertise of appraisers. Real estate is one of the fields of high public interest, and since most ESGs have been conducted centered on the role of private companies, the role of the expert group or the role of public corporations and public institutions is relatively insufficient. If a company or general company engaged in the real estate investment business establishes the role of the Korea Appraisers Association to revitalize ESG management using appraisers, such as ESG appraisers, when investing in real estate, it is believed that it will be possible to promote efficient and sound development of the real estate industry. It was judged that a study on a group of experts was also necessary. In addition, even if the impact of Covid-19 is excluded, it is necessary to gradually introduce an appraisal using non-face-to-face or various advanced technologies (the 4th industry). This study differs from previous studies in that it focused on the role of ESG by the Korea Association of Property Appraisers while research on the role of ESG in public institutions or expert groups is being actively conducted in recent years.

  • This study was a descriptive study to investigate factors affecting quality of life in the Korean elders with diabetes mellitus. A secondary data analysis was conducted using the data of "The Fourth Korea National Health and Nutrition Examination Survey, 2008." The survey included 9774 adults aged over 64 years with diabetes mellitus and 226 samples were used for this study. Data analysis was conducted using SPSS 12.0 program and descriptive statistics, Pearson's correlations, and multiple regression analyses were performed. Correlation analysis showed that quality of life was associated with the amount of alcohol intake, the level of stress awareness, walking time, and suicidal thoughts. The amount of alcohol intake, the level of stress awareness, walking time, and suicidal thoughts accounted for 34.5% of quality of life. These findings suggest that nursing researchers need to consider age, suicidal thoughts, and drinking as important factors affecting quality of life of Korean elders with diabetes mellitus and nursing intervention focusing on the issues needs to be developed.

  • This study was aimed to examine the effects of intermittent walking on health related fitness and metabolic syndrome risk factors in elderly women. Forty five elderly women were randomly assigned to three groups: three 10-min walks per day, one 30-min walk per day or no exercise, respectively. Both walking groups exercised three days a week at moderate intensity for 12 weeks. Two-way repeated measures ANOVA was used to test the hypothesis with a significant level of α = .05. The results indicated that body composition(body weight, body mass index, percent body fat), muscle endurance, flexibility and cardiorespiratory fitness significantly increased after 12 weeks for both walking groups. However, it was found that muscle strength significantly increased only in a continuous walking group. Metabolic syndrome risk factors comprised of waist circumference, systolic blood pressure, triglyceride, high-density lipoprotein, and fasting glucose were significantly improved in both walking groups. In addition, there was a difference in these metabolic syndrome risk factors between pre and post exercise. The results of this study support the hypothesis that intermittent walking has a significant impact on health related physical fitness and metabolic syndrome rick factors in elderly women as continuous walking does.

  • The working time for loading and transporting containers in the container terminal is one of the factors directly related to port productivity, and minimizing working time for these operations can maximize port productivity. Among working time for container operations, the working time of yard tractors(Y/T) responsible for the transportation of containers between berth and yard is a significant portion. However, it is difficult to estimate the working time of yard tractors quantitatively, although it is possible to estimate it based on the practical experience of terminal operators. Recently, a technology based on IoT(Internet of Things), one of the core technologies of the 4th industrial revolution, is being studied to monitoring and tracking logistics resources within the port in real-time and calculate working time, but it is challenging to commercialize this technology at the actual port site. Therefore, this study aims to develop yard tractor working time prediction model to enhance the operational efficiency of the container terminal. To develop the prediction model, we analyze actual port operation data to identify factors that affect the yard tractor's works and predict its working time accordingly.

  • The pallet, typically a form of tertiary packaging, is a flat structure used as a base for the unitization of goods in the supply chain. In addition, standard pallets such as T-11 and T-12 are used throughout the logistics industry to reduce the cost and enhance the efficiency of transportation. However, in the case of special cargo, it is impossible to handle such cargo using a standard pallet due to its size and weight, so many have developed and are now using their customized pallet. Therefore, this study suggests a pallet size optimization method to calculate the optimal pallet size, which minimizes the loss of space on a pallet. The main input features are the specifications and the storage quantity of each cargo, and the optimization method that has modified the Neighborhood Search Algorithm calculates the optimal pallet size. In order to verify the optimality of the developed algorithm, a comparative analysis has been conducted through simulation.
