The recent Sichuan earthquake(2008) in China and Iwate-Miyazaki earthquake(2008) in Japan give Korea peninsula warning that it is no more safety zone against damage by earthquake events. So, rapid and appropriate countermeasures for dam operation and management against earthquake are needed. In Korea earthquake design standard(MOCT, 1997) has been revised after Kobe earthquake. Installation of seismometer and monitoring of earthquake for special class dams is requlated in dam aseismic design standard(MOCT, 2001). Accelerometer installation project for existing dams has been carrying out by K-water to establish an earthquake network for dam safety. Real-time dam earthquake monitoring network has also been developed to detect an earthquake efficiently and to warn to dam administrators as soon as possible. In this study, dam real-time earthquake monitoring system developed by K-water was introduced and applicability of real earthquake record measured by this system to dam safety management was illustrated.

In this paper, we design a system that can control unmanned mobile objects through communication between unmanned mobile object and control server system using LoRa network which is a dedicated IoT network. It is more efficient when the unmanned mobile object performs the special work by installing the LoRa network applied to the unmanned mobile object control system from the small space house or office hospital to the factory. In this paper, we will discuss the design of a system that can improve the social utilization of unmanned mobile objects by making it possible to communicate the events that occur around other mobile objects from the simplification of the navigation path.

This study was conducted to investigate the actual state of utilization of Korean traditional foods by Korean Americans residing in L.A. area and to provide come policies, to improve their attitudes for Korean traditional foods. The proper period preparing traditional foods was the occasion of family events(47.0% )and Korean festivals(40.8%). Festival foods were prepared in Sulnal( =New Year's Day), Chusok( =the Korean Thanksgiving Day), Daeborum( =the 15th of January by the lunar calendar), Dongji( =the winter solstice) and Tano( =the 5th day of the 5th by lunar month), respectively. Sixty five percent of all the respondents expressed their wish to hand down the cooking methods of traditional foods. However, only28.6% of the respondents at their twenties replied positively on this matter. To maintain and develop traditional foods abroad, it is necessary that older generations sometimes offer opportunities to meet with them to the coming korean generations to taste traditional foods and that Korean food companies establish special selling agencies abroad and export standardized traditional foods. And furthermore, if tourism corporations and cooking schools hold a food exhibition and or a food-tasting party, occasionally, in conjunction with the embassies and legations abroad, the utilization of traditional foods will increase.

For a good product quality and plant safety, it is necessary to implement the on-line monitoring and diagnosis schemes of industrial processes. Combined with monitoring systems, reliable diagnosis schemes seek to find assignable causes of the process variables responsible for faults or special events in processes. This study deals with the real-time diagnosis of complicated industrial processes from the intelligent use of multivariate statistical techniques. The presented diagnosis scheme consists of a classification-based diagnosis using nonlinear representation and filtering of process data. A case study based on the simulation data was conducted, and the diagnosis results were obtained using different diagnosis schemes. In addition, the choice of future estimation methods was evaluated. The results showed that the performance of the presented scheme outperformed the other schemes.

This study investigated data on beef dietary consumption during the Joseon Dynasty Period, including "the Annals of the Joseon Dynasty", "the Diaries of the Royal Secretariat", and "Ilsongnok". Beef stands for superstitions as well as respect, broad-mindedness, exquisite culinary taste, and is a symbol of taste. In the historic record, we found two extremely opposite trends; specifically, Ugeum (牛禁, forbidding beef consumption and indulgence in beef). On the one hand, believing that they were the rudimentary foundation to Korea's agriculture, Joseon authorities tried to protect cows and bulls as valuable agricultural assets. Meanwhile, there were several officially sanctioned beef consumption events in the Joseon period. These included Jesu (祭需, food for ancestral rites), Daejup (待接, servings), Hasa (下賜, bestowment), and Hogue (犒饋, comforting soldiers with culinary methods). These included offerings to the departed spirits, servings, bestowment, and comforting soldiers with culinary methods. Especially in Joseon's Yeonhang (燕行) Journals, we can see different beef distributions and preferences between Japan and China. Furthermore, The Annals of the Joseon Dynasty even addressed the general issue of beef treatment; special methods for beef processing, beef distribution, tool materials, and prices of beef.

One of the biggest change in the history of the Journal of Korean Neurosurgical Society[JKNS] had been introduced in 2005. From January 2005, all manuscripts submitted to JKNS should be written in English. This new regulation was followed by many changes in characteristics of the papers published on JKNS in 2005. The authors present an analysis of papers published on JKNS and compared with those of 2004 and 2003. In total, 184 articles were published in 2005. Since a review article was requested by the editorial office to the authors, 183 articles were peer reviewed. Eighty five clinical articles, 75 case reports, 19 laboratory investigations, two special articles and two technical reports were printed. This distribution was not statistically different from 2004's distribution [p=0.67], even though the ratio of clinical articles was decreased to 46.4% from 54.4%. Due to the change in language specification, English articles were increased with statistical significance [p<0.001]. There were several events related with copyright of the contents of the papers published on JKNS. We think these are some good points came with change in official language to English. General trends of the papers seemed to be in the right way.

Acoustic emission analysis is an effective technique for monitoring the evolution of damage in a structure. An experimental analysis on a set of reinforced concrete beams under flexural loading was carried out. A mixed AE analysis method which used both parameter-based and signal-based techniques was presented to characterize and identify different failure mechanisms of damage, where the signal-based analysis was performed by using the Hilbert-Huang transform. The maximum instantaneous energy of typical damage events and the corresponding frequency characteristics were established, which provided a quantitative assessment of reinforced concrete beam using AE technique. In the bending tests, a "pitch-catch" system was mounted on a steel bar to assess bonding state of the steel bar in concrete. To better understand the AE behavior of bond-slip damage between steel bar and concrete, a special bond-slip test called pullout test was also performed. The results provided the basis of quantitative AE to identify both failure mechanisms and level of damages of civil engineering structures.

Multiple waves of COVID-19 highlighted one crucial aspect of this pandemic worldwide that factors affecting the spread of COVID-19 infection are evolving based on various regional and local practices and events. The introduction of vaccines since early 2021 is expected to significantly control and reduce the cases. However, virus mutations and its new variant has challenged these expectations. Several countries, which contained the COVID-19 pandemic successfully in the first wave, failed to repeat the same in the second and third waves. This work focuses on COVID-19 pandemic control and management in Saudi Arabia. This work aims to predict new cases using deep learning using various important factors. The proposed method is called Deep Learning and Dynamic Weighing-based (DLDW) COVID-19 cases prediction method. Special consideration has been given to the evolving factors that are responsible for recent surges in the pandemic. For this purpose, two weights are assigned to data instance which are based on feature importance and dynamic weight-based time. Older data is given fewer weights and vice-versa. Feature selection identifies the factors affecting the rate of new cases evolved over the period. The DLDW method produced 80.39% prediction accuracy, 6.54%, 9.15%, and 7.19% higher than the three other classifiers, Deep learning (DL), Random Forest (RF), and Gradient Boosting Machine (GBM). Further in Saudi Arabia, our study implicitly concluded that lockdowns, vaccination, and self-aware restricted mobility of residents are effective tools in controlling and managing the COVID-19 pandemic.

The purpose of this study is to suggest a direction for the development of unlined underwear design. A style for unlined underwear can take strong points and compensate for weak points by using the characteristics of wire brassieres and bralettes. As a method for research, we based our study on literature and data such as previous studies, professional books, internet articles, and fashion magazines. As a result of analyzing the brassiere's status in lines like 'FOREVER 21' and 'VICTORIA'S SECRET', we determined that 'FOREVER 21' reflects the trend of unlined style underwear, and 'VICTORIA'S SECRET' has both unlined and wire brassieres to make breast correction. In the case of unlined style brassieres, a wire is put in order to gather the chest for compromising comfort and correction. In order to express the possibility of expressing various feelings even in unlined style, Design 1 lets everyone know that unlined underwear can be very comfortable as a daily, not used only occasionally for events. Design 2 demonstrates that besides the artificial feeling of using the strap for a special day or event, it can be expressed naturally by using the lace as it is. Design 3 expresses the luxurious and sexy, rather than the low-grade decadent sexy, by using the feeling of the single layer lace and the pearl decoration for wedding and honeymoon.
