The purpose of this study was to apply a teaching method that fits the characteristics of learners through the improvement and application of subjects for reinforcing SWP, and to seek ways to strengthen field practice. As a result of the study, first, as a method of applying learner motivation, it is necessary to conduct discussions by inviting practitioners in the field, and to watch the progress of projects by type of social welfare site. Second, as a way to participate in learners, it is necessary to analyze excellent proposals, participate in events held at welfare sites, present various dilemma cases in the field, and try to overcome ethical dilemmas by sharing cases overcoming dilemma, and to make efforts to list practical skills required in social welfare field practice. Third, it is necessary to apply such methods as phone calls, e-campus, Kakao Talk, Zoom, and counseling techniques that are conducted in the case management process as a way to apply interaction, and discuss issues that are important in the welfare field.

The purpose of this study is to examine the experience of case management practice for residents of low - income housing. The importance of the house for the vulnerable residents with homelessness is absolute, and case management that supports them to live as residents in the community is also very important. Nevertheless, the research so far has focused on the supply of affordable housing, the residential environment, the quality of life of the tenants, and the health, but there was a lack of interest in case management practices. In this study, we investigated the experience of case management practice by listening 10 case managers's experiences through FGI interview. As a result of the study, the case manager's experience is divided into four themes: 'Dilemma of support for the independent housing life after the facilities', 'Role competition between rent management and case management', 'Lonely practice for linkage and cooperation with the mainstream community support system', 'Double employment relationship and poor working environment' respectively. Based on their experiences, this study suggests practical and practical suggestions for case management of rental housing.

Because students majoring in construction-related fields must develop a broad repository of knowledge and skills, effective transferal of these is the primary focus of most academic programs. While inculcation of this body of knowledge is certainly critical, actual construction projects are complicated ventures that involve levels of risk and uncertainty, such as resistant neighboring communities, unforeseen weather conditions, escalating material costs, labor shortages and strikes, accidents on jobsites, challenges with emerging forms of technology, etc. Learning how to develop a level of discernment about potential ways to handle such uncertainty often takes years of costly trial-and-error in the proverbial "school of hard knocks." There is therefore a need to proactively expedite the development of a sharpened intuition when making decisions. The AGC Education and Research Foundation case study committee was formed to address this need. Since its inception in 2011, 14 freely downloadable case studies have thus far been jointly developed by an academics and industry practitioners to help educators elicit varied responses from students about potential ways to respond when facing an actual project dilemma. AGC case studies are typically designed to focus on a particular concern and topics have thus far included: ethics, site logistics planning, financial management, prefabrication and modularization, safety, lean practices, preconstruction planning, subcontractor management, collaborative teamwork, sustainable construction, mobile technology, and building information modeling (BIM). This session will include an overview of the history and intent of the AGC case study program, as well as lively interactive demonstrations and discussions on how case studies can be used both by educators within a typical academic setting, as well as by industry practitioners seeking a novel tool for their in-house training programs.

Structural acceleration regulation is a means of managing structural response energy and enhancing the performance of civil structures undergoing large seismic events. A quadratic output regulator that minimizes a measure including the total structural acceleration energy is developed and tested on a realistic non-linear, semi-active structural control case study. Suites of large scaled earthquakes are used to statistically quantify the impact of this type of control in terms of changes in the statistical distribution of controlled structural response. This approach includes the impulses due to control inputs and is shown to be more effective than a typical displacement focused control approach, by providing equivalent or better performance in terms of displacement and hysteretic energy reductions, while also significantly reducing peak story accelerations and the associated damage and occupant injury. For earthquake engineers faced with the dilemma of balancing displacement and acceleration demands this control approach can significantly reduce that concern, reducing structural damage and improving occupant safety.

In the conventional speech processing, the technique of FFT(Fast Fourier Transform) is usually applied to the finite number of samples within the window of specified length using the fixed sampling rate. In this case, the temporal resolution is dependent upon the length of window while the spectral resolution is dependent upon the number of samples within the window. Thus, once the temporal resolution is determined the spectral resolution is also determined or vice versa. To resolve this type of dilemma, a new type of bank-filter similar to the characteristics of cochlear model needs to be considered. Furthermore, wide dynamic range of cochlea certainly helps the stable extraction of speech features. In the paper, the human auditory system will be briefly introduced and previous works on auditory preprocessors based on cochlear model will be reviewed. As a conclusion, the design considerations of auditory preprocessors based on cochlear model will be addressed.

In the 21st century modem architecture, not only environmental problems and sustainable development but also two subjects, 'Globalization' and 'Localization', have become important issues. The modern application of vernacular design which is the design model including the characteristics of region, a people and tradition can be a solution for localization and sustainable development. Vernacular design gives many ideas in respect of organic art and design, the dilemma of modern architecture, and practical solution of its problems, and is considered as an important resource of modern ecological architecture. This study aims to investigate the meaning and types of vernacular design and confirm the development possibility of this design as the important element of modem regional ecological architecture. In addition, through case studies, it will demonstrate that the regional ecological architecture based on vernacular design can solve new multidimensional architectural problems in the 21st century.

The purpose of this paper is to develop the pattern recognition system with a 'Robust' concept to be applicable to flexible manufacture automation in practice. The 'Robust' concept has four meanings as follows. First, pattern recognition is performed invariantly in case the object to be recognized is translated, scaled, and rotated. Second, it must have strong resistance against noise. Third, the completely learned system is adjusted flexibly regardless of new objects being added. Finally, it has to recognize objects fast. To develop the proposed system, contouring, spectral analysis and Fuzzy ART neural network are used in this study. Contouring and spectral analysis are used in preprocessing stage, and Fuzzy ART is used in object classification stage. Fuzzy ART is an unsupervised neural network for solving the stability-plasticity dilemma.

We present a case of hydrocephalus as the primary manifestation of neurosarcoidosis. Sarcoidosis is a rare disease in Korea and its incidence is much lower than that of tuberculosis. Diagnosis is made by pathologic findings and by exclusion of other granulomatous disorders. Neurosarcoidosis is observed in approximately 5% of sarcoidosis. Its common manifestations are facial palsy (50% of patients with neurosarcoidosis) and optic neuritis. Hydrocephalus is a very uncommon reported finding. Although the typical presentation of sarcoidosis such as facial palsy is not a diagnostic dilemma, more atypical presentations such as hydrocephalus with altered mentality in a tuberculosis patient can lead to a misdiagnosis.

The bronchopleural fistula[BPF] due to bronchial stump disruption after pneumonec-tomy has remained one of the most dreadful complications to now. The management of the BPF with empyema thoracis are still therapeutic dilemma even though a various surgical methods for the control of BPF with or without empyema thoracis. We have experienced the successful treatment of BPF & empyema thoracis with transsternal transpericardial approach. The patient was a 54 years old male who was taken left pneumonectomy at W. Medical Center at sept, 19th. 1991. He was suffered from the BPF R empyema thoracis and so was transferred to our hospital at Nov. 19th. 1991. We treated the patient with transsternal transpericardial bronchial closure for BPF, and put clagett procedure for empyema thoracis in 2 weeks. We think this kind of surgical techniques is one of the relatively simple and effective method for the control of BPF and empyema thoracis.

Sinonasal sarcoidosis in the head and neck region is infrequent. Its occurrence can be either isolated in combination with other systems. The literature reveals that the occurrence of sinonasal sarcoidosis without lung involvement is rare. In general, sarcoidosis is a chronic non-caseating granulomatous disease of unknown origin, often identified after biopsy. In this article, we report on a benign tumor of the face that produced a diagnostic dilemma, necessitating refinement of the surgical access and in toto removal of the benign tumor.
