Construction projects have shown a dramatic increase in size and complexity during the recent years that precise management has been recognized as one of key factors leading the project to success. It has been investigated that management in construction sites is generally done based on the experience of site engineers. Such experience based decision making lacks reliability that could bring disastrous results such as delay and cost overruns. The purpose of this study is to suggest a process progress pattern analysis method that is expected to be used as an objective reference for site managers to aid the decision making done regarding process progress management.

Today the usage of DB already becomes an important issue for many companies' survival. Especially, the companies which have adopted CRM could not gain the return to be expected because of the lack of understanding about the relationship with customers. Professor Schmitt introduced 'the complete CEM(Customer Experience Management) model', but no specific methodology for analysis was introduced. Therefore, in this study we use HOQ, GA, and ANP to build 'the complete CEM model' and present the integrated CEM model based on the integrated analytic process to help the company's decision about the stage to be begun first out of 5 stages of CEM and the priorities of investment in customer experiences.

A mobile crane has been more frequently used to deal with the increased capital-intensive projects in line with the economic growth, but the operation is still heavily dependent on personal experience in the past, resulting in severe overturn accidents that cause the loss of lives and damage to the properties. A crane shall be installed in a systematic manner that proved to be safe in engineering aspect, and should the installation and operation be blindly dependent on experience alone, it would apparently cause a great risk. Particularly the mobile crane, among others, frequently causes a severe overturn accident due to poor ground-fixing device. The study therefore focused on fixing system of mobile crane and the outcome is highly expected to make a great commitment to selecting the optimal type of crane for the project as well as to securing the safety during construction.

Ship technology has advanced in many diverse directions in recent years, a trend that can be expected to continue. The effect of this both on the physical equipment now being usedand under construction and on the attitude of mind of many of those responsible for its operation is profound. The technological changes in shipping have brought about an increasing trend towrard more delegation of authority from shoreside to ship management. With increased shipboard responsibility the shipping industry would benefit from seeming that more of the management subjects were learned by nautical students. It is clear advantage that companies should draw into their general management structure men with seafaring experience. At the same time the the boards of shipping companies should include more men with high technological qualificatiions and experience.

The Canadian experience-universal government health insurance administeredby the ten provinces and two territories with some fiscal and policy variations-suggests the possibility of more effectve and efficient health care delivery system. The central purpose of the Canadian health in surance was to reduce and hopefully eliminate financial barriers to medical care. In this it succeeded. But it also produced varous kinds of unexpected side-effects on cost and quality. The Federal and Provincial Governments of Canada continue to exert theri efforts to ameliorate these problems. The lesson from Canada is that the health care revenue should be raised at the national level and managed at the regional level, and the regional healthcare financing organization has to take over the functions of the public health center. These alternatives is expected to make the Korean health care delivery system more efective and efficient, and to achieve health for all. This paper also discussed the policy agenda for implementing such alternatives in Korea.

Purpose: The study was a qualitative study to examine the synchronous and asynchronous distanced learning experience of online paramedic students during the COVID-19 pandemic. Methods: The subjects included 10 students enrolled in the department of emergency medical service at J City C University. Written consent was provided by the subjects prior to the study, and focus group interviews were then conducted with sufficient explanation. The interviews were recorded and were directly transcribed immediately after the interview. Research results were then derived through content analysis. Results: A total of 4 domains and 9 categories were derived from the experiences of paramedic students on distanced learning. The 4 domains included "distanced lectures type," "student's adaptation and non-adaptation," "change of evaluation," and "learning anxiety." Conclusion: Contents of each domain derived from this study are expected to be used as basic data for the design of the distanced learning in the future.

The purpose of this study is to develop an evaluation method for online design education. Online education has established itself as the primary form in the educational field, however, there are unsatisfactory response from instructors and students due to rapid conversion of online education. Due to the transition of educational method, online class contents have become optimized and online educational experiences became accumulated. However, clear education criteria is essential. This study states importance of two parts: establishing an evaluation system based on design thinking for online design education and finding appropriate online platforms for interaction between instructors and students. The research results provide implications for ensuring the efficiency of design education and are expected to contribute significantly to the future education field.

In this paper, we introduce a reinforcement learning-based algorithm for personalized tourist path recommendations. The algorithm employs a reinforcement learning agent to explore tourist regions and identify optimal paths that are expected to enhance tourism experiences. The concept of tourism experience is defined through points of interest (POI) located along tourist paths within the tourist area. These metrics are quantified through aggregated evaluation scores derived from reviews submitted by past visitors. In the experimental setup, the foundational learning model used to find tour paths is the Deep Q-Network (DQN). Despite the limited availability of historical tourist behavior data, the agent adeptly learns travel paths by incorporating preference scores of tourist POIs and spatial information of the travel area.

Objective: Falls are defined as contact of the body with the floor after losing balance during activities of daily living. Falls commonly occur among the elderly, and stroke patients in particular are at a high risk of falling. The purpose of this study was to investigate the changes of temporal and spatial gait parameters and gait symmetry according to experience falls in post-stroke patients. Design: Cross-sectional study. Methods: Fifty three patients with stroke were recruited on a voluntary basis from the rehabilitation unit, who currently undergoing physical therapy. All participants were asked to answer questions regarding the frequency of falls in the past 1 year. Fifty-three patients with stroke were allocated 2 groups according to experienced falls: stroke with falls (n=26) during past 1 year and stroke without falls (n=27). The spatial and temporal gait parameters and gait symmetry ratio were measured using GAITRite system. Results: The spatial gait parameters and the temporal gait parameters were significantly different between the stroke with falls group and the stroke without falls group (p<0.05). Furthermore, step length was the only significantly different among symmetry ratio (p<0.05). Conclusions: Experience of falls can lead to impairment of gait ability in stroke patients. This result is expected to be used as a basic data for rehabilitation program development to prevent a fall of post-stroke patients.

We reviewed our entire experience of 44 consecutive patients undergoing the arterial switch operation [ASO] for transposition of the great arteries [TGA] since March 1985.There were 28 patients with simple TGA[group I] and 16 with associated ventricular septal defect[VSD] [Group II] There were five hospital deaths[11.4%, 5/44], two related to single right coronary artery anatomy. There have been no late deaths. For group I hospital mortality was 14.3%[4/28], and for group II this was 6.25%[1/16]. Mean follow-up was 3.3 years[range 1 month to 8 years] and was completed for all patients. Actuarial survival at 7 years for hospital survivors was 85 $\pm$ 3.2 % in group I and 94 $\pm$ 3.5% in groupII. One patient has mild asymptomatic left ventricular outflow tract obstruction, and five patients [12.8 %,5/ 39] have right ventricular outflow tract gradients[RVOTO] exceeding 25 mmHg; only one patient has required reoperation for RVOTO. Mild neoaortic regurgitation is present in one patient. All survivors are currently in NYHA class I without medicalion, and all are in sinus rhythm. The ASO is associated with low operative risk and excellent medium-term outcome in most subsets of patients undergoing this operation. With more experience, improved results can be expected also in those patients currently at higher risk.
