A new heuristic algorithm for the heterogeneous single container loading problem is proposed in this paper, This algorithm fills empty spaces with the homogeneous load-blocks of identically oriented boxes and splits residual space into three sub spaces starting with an empty container. An initial loading pattern is built by applying this approach recursively until all boxes are exhausted or no empty spaces are left. In order to generate alternative loading patterns, the load-blocks of pattern determining spaces are replaced with the alternatives that were generated on determining the load-blocks. An improvement algorithm compares these alternatives with the initial pattern to find improved one. Numerical experiments with 715 test cases show the good performance of this new algorithm, above all for problems with strongly heterogeneous boxes.

The recent change of social environment has influence on the configuration of space for the social welfare center. And so the relation of space and function required the change of spatial configuration. The social welfare center fills the role of family welfare, domiciliary care, community organization etc. In such sence, this study explore the conditions of spatial configuration for the domiciliary and community care unit of social welfare centers in small city. For this study, it was investigated the space role and funtion, the service program, the usage characteristics, the room satisfaction of social workers. In sum, the useful data were collected, analyzed, and colligated by case study. It could be used in the design criteria of domiciliary care unit for the social welfare center in small city.

The expansion of old road is needed in constructing the entrance at the $\bigcirc$$\bigcirc$I/C road in $\bigcirc$$\bigcirc$city. To strength the national competition, many agents who concerned do their best for finishing that construction early as soon as possible. In generally, soil embankment on soft foundation is caused to reduce the stability by making the settlement of ground surface due to the over load. Thus, we try to make it stable by building EPS embankment construction which in our working place is one kind of the method of light embankment construction after excavating the original ground.

All Deficiency section (諸虛門) in Euibangyoochui (醫方類聚), fills volumes 143-154 of Euibangyoochui's 266 volumes. In it, diverse and meaningful concepts such as Consumptive Disease (虛勞) and Fatigue Due to Overexertion (勞倦) are introduced to describe deficiency-oriented diseases. Before the 10th century, there are classified into six categories: muscle exhaustion, pulse exhaustion, flush exhaustion, Qi exhaustion, essence exhaustion, bone exhaustion, and prescribing treatments for treating diseases corresponding to each exhaustion. As medical knowledge was integrated through the medical books compiled by the government, awareness of Consumptive Disease was advanced to clarify the concept of pathways. The Confucian doctors have led to changes in recognition of the cause of the Consumptive Disease from damage of human factors to an internal problem. It can be seen that the classification of hurdles has become more diverse just before the outbreak of Euibangyoochui and that they include various diseases.

Objectives : I investigated the organization and contents of "Sanghanbyeollyu(傷寒辨類)" in order to grasp its bibliographical points. Methods : I compared "Sanghanbyeollyu(傷寒辨類)" with "Sanghanmyeongniron(傷寒明理論)", "Uihagimmun(醫學入門) Sanghan(傷寒)" in side of their organization and contents. Results : The first volume in "Sanghanbyeollyu" is composed of various theories, the second volume in it is composed of many symptoms. The second volume include 49 symptoms in "Sanghanmyeongniron" excepting 1 symptom, its organization is similar to the organization in "Uihagimmun Sanghan". Besides the frequency of prescription quoted in both "Sanghanbyeollyu" and "Uihagimmun Sanghan" is 251, the frequency of prescription quoted only in "Sanghanbyeollyu" is 617, the frequency of prescription quoted only in "Uihagimmun Sanghan" is 622. Thus, "Sanghanbyeollyu" is not a duplicate of "Uihagimmun Sanghan" because of the frequency of prescription quoted. Conclusions : I have found out that "Sanghanbyeollyu" does not only adopt the merits from "Sanghanmyeongniron", but also fills its organization and contents with "Uihagimmun Sanghan".

Despite the increasing adoption of gamification and its huge potential in tourism, research in gamification is still limited. As preliminary findings show that the effectiveness of gamification depends on the context of its application and the players' use of the gamified app, this paper fills in these gaps: by exploring and analysing the application of gamification in a specific e-commerce tourism context; and assessing the gamification's effectiveness by measuring the players' gamification usage and the latter's behavioural and psychological outcomes. The gamified TripAdvisor website and its Facebook enabled gamification app are used as the specific context of the study. Findings from a survey conducted on TripAdvisor users provide useful practical and theoretical implications to gamification designers and researchers alike on how game mechanics can be designed for enhancing the users' motivation, flow, task involvement and engagement with the 'play' tasks, and so, increasing the gamification's effectiveness.

Ultrasonic Time-of-Flight Diffraction (TOFD) techniques are useful methods for non-destructive evaluation of fracture characteristics. This study focuses on the reliability and accuracy of ultrasonic diffraction methods to estimate the depth of rock fractures. The study material includes three different rock types; andesite, basalt and ignimbrite. Four different ultrasonic techniques were performed on these intact rocks. Artificial near-surface fracture depths were created in the laboratory by sawing. The reliability and accuracy of each technique was assessed by comparison of the repeated measurements at different path lengths along the rock surface. The standard error associated with the predictive equations is very small and their reliability and accuracy seem to be high enough to be utilized in estimating the depth of rock fractures. The performances of these techniques were re-evaluated after filling the artificial fractures with another material to simulate natural infills.

This paper fills a gap in smart tourism research by investigating the link between online representations and their physical counterparts. This sort of phenomenology visualizes a doubled cultural mimesis that can be described by the story of the ship of Theseus, where the original is replaced by an ongoing process of installing new components. In this sense, social reality is conceptualized as having real cultural events and the production of cultural items as well as having digital reproductions that appear and circulate online. These are accessed by a variety of platforms where reality is simulated onsite through augmented reality technology or remotely through forms of virtual reality. This paper seeks to frame and to present this notion and its potential impacts on destination culture particularly during the COVID-19 pandemic in Korea.

In this paper, we study the effect of noise on video inpainting, a technique that fills missing regions of video. Since the video may contain noise, the quality of the video may be affected when applying the video inpainting technique. Therefore, in this paper, we compare the inpainting performance in video with and without denoising techniqueDAVIS dataset. For that, we conducted two experiments: 1) applying inpainting technique after denoising the noisy video and 2) applying the inpainting technique to the video and denoising the video. Through the experiment, we observe the effect of denoising technique on the quality of video inpainting and conclude that video inpainting after denoising would improve the quality of the video subjectively and objectively.

A vast amount of labeled data is required for deep neural network training. A typical strategy to improve the performance of a neural network given a training data set is to use data augmentation technique. The goal of this work is to offer a novel image augmentation method for improving object detection accuracy. An object in an image is removed, and a similar object from the training data set is placed in its area. An in-painting algorithm fills the space that is eliminated but not filled by a similar object. Our technique shows at most 2.32 percent improvements on mAP in our testing on a military vehicle dataset using the YOLOv4 object detector.
