In the Republic of Korea, there's been a culture called 'Hyo' since Koryo Dynasty and this word represents the meaning of paying utmost respects to one's own parents and ancestors whether they are alive or have passed. However, nowadays, most of people live away from their family gravesites so that they do not and cannot take care of them except on the special holidays. For this reason, people could not respond promptly to the incidents occurred at the sites as they receive notifications much later dates most of the time. Thus, in this paper, we propose a low-cost gravesite monitoring system which the users can immediately respond to the disastrous events after being informed of current situations through PLC without delay. For the performance evaluation, the lab and test bed experiments were performed on an actual ship using 200Mbps and 500Mbps products instead of performing an on-site experiment after the system has actually been constructed. The Mountain Region PLC was installed on the power lines and the result showed successful 36.14Mbps communication. Therefore, we expect that this study will contribute in time and cost reduction while constructing the internet infrastructures in mountain regions or building the Smart-graves, tumulus, and charnel houses.

With the advent of westernized diet and a lack of exercise, young female college students are paying more attention to their bodyweight and health. Whole-body vibration has been demonstrated to be a suitable training method for improving knee extension maximal strength in young female athletes, as well as the gait performance in elderly women. This study aimed to evaluate the effects of a vertical vibration intervention on the physical fitness and postural balance in young females. Fifty-four young women were recruited; all subjects were randomly assigned to the intervention group and control group. The intervention group underwent vertical vibration with a platform for 12 weeks. The results showed that body mass index and body fat percentage had decreased (P<0.05). In addition, their muscle endurance as indicated by a sit-up test and their flexibility as indicated by a sit-and-reach test were both increased. With regard to postural balance, their 30-second sit-to-stand and timed up and go test results were improved. At the same time, their mean single-leg stance with eyes closed time increased (P<0.05). However, there were no significant differences, meanwhile, for the control group. Overall, the results showed that the whole body vibration (WBV) intervention had some beneficial effects on physical fitness and postural balance in young women.

The block assembly process takes more than half of the total shipbuilding processes. Therefore, it is very important to have a practically useful block assembly process planning system which can build plans of maximum efficiency with minimum man-hours required. However, the process plans are often not readily executable in the assembly shops due to severe imbalance of workloads. This problem arises because the process planning is done on block by block basis in current practice without paying any attention to the load distribution among the assembly shops. this paper presents the development of an automated hull block assembly process planning system which results in the most effective use of production resources and also produces plans that enable efficient time management. If the load balance of assembly shops is to be considered at the time of process planning, the task becomes complicated because of the increased computational complexity. To solve this problem, a new approach is adopted in this research in which the load balancing function and process planning function are iterated alternately providing to each other contexts for subsequent improvement. The result of case study with the data supplied from the shipyard shows that the system developed in this research is very effective and useful.

Purpose: Unemployment in its general form is a result stemming from the decisions of workers to search for a new and better paying job. In this study, the view that unemployed workers were not simply desiring any job, but one that would maximize their expected future outcome, was examined. Research design, data, and methodology: In order for collection of data and analysis, the panel dates of individual applications for job openings on job search websites were utilized to examine search effort and period for individuals. Results: It was found that the number of applications sent by a job seeker declined over their period of job searching, and that job seekers over a long duration of time tend to send relatively more applications per week throughout their entire search period. The latter finding contradicts the implications of the standard labor search effort models. Conclusions: It can be observed that these job search models fail to capture several key elements in search efforts, and that the search time for an offer is not entirely predetermined by the labor market conditions and socio-economic (individual) characteristics of the searcher. It can be shortened as he or she intensifies their job search efforts.

Based on existing research, the psychological state of Chinese students has become a very significant issue that needs to be resolved. In addition to paying attention to the daily life and study of Chinese students, the psychological problems of Chinese students are also worthy of attention. At the same time, if the existing psychological problems are not resolved in time, serious consequences may result. Based on the ART(Attention Restoration Theory) theory, this article uses VR (Virtual Reality) content as a medium, uses 3D modeling software to build a healing scene that helps Chinese students improve their psychological and emotional state, and presents it in a VR device. To achieve the purpose of improving the psychological and emotional state of Chinese students. According to experimental tests, the VR recovery scene constructed by this method can help improve the psychological mood of Chinese international students who already have subliminal depression. The results of independent sample T-tests after data analysis experiments show that after the intervention of the experiment, the depression of the experimental group is significantly improved compared to the control group. It is proved that the method in this study is effective for the mentality and emotion of Chinese international students who have subliminal depression. There is a significant improvement effect.

In response to recent changes in gender equality and social awareness among female college students, we sought to investigate whether there were corresponding changes in their preferred fashion styles and items. A survey was conducted with 200 women in their twenties to determine whether they were aware of gender equality and social change, as well as their preferred fashion styles and items at both the time of college admission and the current time. Awareness of gender equality was divided into two factors: feminism and a perceived increase in women's social power. A significant difference was observed in the fashion styles of female college students in their twenties between the time of admission and the current time. Compared with the past, the preferred style has changed to gender-neutral rather than feminine, useful rather than aesthetics, character rather than fashion, sporty rather than elegance, and casual rather than formal. Preferred items included pants rather than skirts, sneakers rather than shoes, socks rather than stockings, long skirts rather than short skirts, and backpacks rather than handbags. The level of attention paid to campus attire per week decreased over time. No correlation was found between gender equality awareness and preferred fashion style, while feminism was correlated with preferred fashion items. The degree to which attention was paid to campus attire per week was correlated with feminism, but was not correlated with a perceived increase in womens' social power.

This study analyzed the attention concentration tendencies of one(1) subject who showed convergent exploratory acts actively through the gaze-brainwave measurement experiment of cafe space images and our research findings are as follows. First, the areas of interest (AOIs) that the subject gazed visually by paying attention to it and concentrating on it at a cafe space include counter&menu area, sign area, partition area, image wall area, stairs area, and movable furniture area, and built-in furniture area: seven areas in total. Second, conscious gaze frequency appeared the highest in counter&menu area, and conscious gaze appeared more later than in initial times. Third, conscious gaze pattern was divided into the zone that explored various areas dispersely (distributed exploratory zone) and the zone that explored between particular areas concentratedly (intensive exploratory zone). Fourth, as a result of analyzing the brainwave attention concentration, it was found that the attention concentration in prefrontal lobe (Fp1, Fp2) and frontal lobe (F3, F4) rose to a higher level in the zone of 15 to 16 seconds and this time zone was considered to be a zone where gazing at counter&menu area was very active. In addition, the attention concentration appeared higher in the initial zone than in the later zone, among the entire experimental time zones. Finally, as a result of analyzing the changes in activation by brain portion of the SMR wave expressed when maintaining the arousal and attention concentration, it was found that the right prefrontal lobe and the frontal lobe became activated in the time zone when the intensive exploration of "counter&menu area" and "movable furniture${\leftrightarrow}$built-in furniture area" had occurred and the time zone when the intensive exploration of "image wall${\leftrightarrow}$partition area" and "counter&menu${\leftrightarrow}$sign area" had occurred.

In the user-centered design paradigm, information systems are created entirely tailored to the users who will use them. When the functions of a complex system meet a simple user interface, users can use the system conveniently. While web personalization services are emerging as a major trend in portal services, portal companies are competing for a second service, such as introducing 'integrated communication platforms'. Until now, the role of the portal has been content and search, but this time, the goal is to create and provide the personalized services that users want through a single platform. Personalization service is a login-based cloud computing service. It has the characteristic of being able to enjoy the same experience at any time in any space with internet access. Personalized web services like this have the advantage of attracting highly loyal users, making them a new service trend that portal companies are paying attention to. Researchers spend a lot of time collecting research-related information by accessing multiple information sources. There is a need to automatically build interest information profiles for each researcher based on personal presentation materials (papers, research projects, patents). There is a need to provide an advanced customized information service that regularly provides the latest information matched with various information sources. Continuous modification and supplementation of each researcher's information profile of interest is the most important factor in increasing suitability when searching for information. As researchers' interest in unstructured information such as technology markets and research trends is gradually increasing from standardized academic information such as patents, it is necessary to expand information sources such as cutting-edge technology markets and research trends. Through this, it is possible to shorten the time required to search and obtain the latest information for research purposes. The interest information profile for each researcher that has already been established can be used in the future to determine the degree of relationship between researchers and to build a database. If this customized information service continues to be provided, it will be useful for research activities.

Recently the abusive calls on on-demand bonds have been a critical issue among many engineering and construction companies in Korea. On-demand bond is referred to as an independent guarantee in the sense that the guarantee is independent from its underlying contract although it was issued based on such underlying contract. For this reason, the issuing bank is not required to and/or entitled to look into whether there really is a breach of underlying contract in relation to the call on demand-bonds. Due to this kind of principle of independence, the applicant has to run the risk of the on demand bond being called by the beneficiary without due grounds. Only where the call proves to be fraudulent or abusive in a very clear way, the issuing bank would not be obligated to pay the bond proceeds for the call on on-demand bonds. In order to prevent the issuing bank from paying the proceeds under the on-demand bond, the applicant usually files with its competent court an application for injunction prohibiting the beneficiary from calling against the issuing bank. However, it is in practice difficult for the applicant to prove the beneficiary's call on the bond to be fraudulent since the courts in almost all the jurisdictions of advanced countries require very strict and objective evidences such as the documents which were signed by the owner (beneficiary) or any other third party like the engineer. There is another way of preventing the beneficiary from calling on the bond, which is often utilized especially in the United Kingdom or Western European countries such as Germany. Based upon the underlying contract, the contractor which is at the same time the applicant of on-demand bond requests the court to order the owner (the beneficiary) not to call on the bond. In this case, there apparently seems to be no reason why the court should apply the strict fraud rule to determine whether to grant an injunction in that the underlying legal relationship was created based on a construction contract rather than a bond. However, in most jurisdictions except for United Kingdom and Singapore, the court also applies the strict fraud rule on the ground that the parties promised to make the on-demand bond issued under the construction contract. This kind of injunction is highly unlikely to be utilized on the international level because it is very difficult in normal situations to establish the international jurisdiction towards the beneficiary which will be usually located outside the jurisdiction of the relevant court. This kind of injunction ordering the owner not to call on the bond can be rendered by the arbitrator as well even though the arbitrator has no coercive power for the owner to follow it. Normally there would be no arbitral tribunal existing at the time of the bond being called. In this case, the emergency arbitrator which most of the international arbitration rules such as ICC, LCIA and SIAC, etc. adopt can be utilized. Finally, the contractor can block the issuing bank from paying the bond proceeds by way of a provisional attachment in case where it also has rights to claim some unpaid interim payments or damages. This is the preservative measure under civil law system, which the lawyers from common law system are not familiar with. As explained in this article, it is very difficult to block the issuing bank from paying in response to the bond call by the beneficiary even if the call has no valid ground under the underlying construction contract. Therefore, it is necessary for the applicants who are normally engineering and construction companies to be prudent to make on-demand bonds issued. They need to take into account the creditability of the project owner as well as trustworthiness of the judiciary system of the country where the owner is domiciled.
