In a ubiquitous computing environment, a ubiquitous smart space is required to help devices provide intelligent services. The smart space embedded with mobile devices should have the capabilities of collecting data and refining the data to contact. Unfortunately, the context information in a ubiquitous smart space has many ambiguous characteristics. Therefore, it is necessary to adapt a standard taxonomy for contact information in the smart space and to implement an inference technique of the context information based on taxonomy. Rule-based inference engine, such as CLIPS, Jess, was employed for providing situation-aware services. However, it is difficult for these engines to be used in resource limited mobile devices. In this paper, we propose a light-weight inference engine providing autonomous situation aware services in mobile environment. It can be utilized for personal mobile devices tuck as mobile phone, PMP and navigation. It can also support both generalized rules and specialized rules as using hierarchical taxonomy information.

In Korea, most of the locations of the cemeteries and burial vault are in forest lands. The utilization of forest land for this particular purpose is very inefficent and considered to be a serious problem. National government (Forest Service), local governments (Incheon city), and religious corporation (eunhoe Temple) are creating new burial methods to solve the inefficiency in forest utilization. In this study, awareness of Koreans and Japaneses on tree burial problems were compared. Based from the results of the survey, more than 80% of the respondents are aware of the problems. However, the burial culture in Korea still has many problems. Operation and management of tree burial is not being done by experts and sufficient information regarding to this type of burial still needs to developed. To solve these problems, eco-friendly burial, which is considered as new funeral culture, is now being created. In the case of Ichinoseki City in Iwate prefecture in Japan, improving the residential environment greatly affected the tree burial practices. This town was chosen for this study due to its characteristics of being a tourism area which greatly affecting the economy of this town. Another study site of this study was located in Sangju city. The changing social environement and the perception of the people regarding on the services being provided to the people were examined thru questionnaire survey. Specifically, this study analyzed the practices and beliefs of the people regarding the tree burial culture.

The International Labor Organization (ILO) selected fishing as the most dangerous group of jobs in the world, and it is well known in Korea as a 4D industry. Offshore large purse seine accounts for the largest portion of the fishing industry in the coastal region with high death rate and the accident rate. The repeated disaster rate survey by the Korea Maritime Institute (KMI) shows offshore large purse seiner is the highest at 22.3 percent and coastal gill nets and offshore stow net are following at 12.4 percent and 11.9 percent in order. Therefore, risk factors occurring in offshore large purse seiners were analyzed based on data from the National Federation of Fisheries Cooperatives (NFFC) for three years from 2015 to 2017 and 4M (Man, Machine, Media, Management) 3E (Engineering, Education, Enforcement) techniques were used to provide a safe fishing environment. The number of accidents on offshore large purse seiners each year was more than 150, and the number of accidents on every fishing boats was as high as 17 percent in 2015. If the accident rate and the risk level were divided by insurance, the accident resulting from contact with machinery was the highest, and the risk of a contact with gear was low but frequently occurring. This was caused by collisions and contact with gear in situations where death and disappearance risk are not high, and accident types in situations where death and loss risk are considered to be contact with machinery, falls or other accidents. Through these analysis techniques, the frequency and risk of each type of accident on a offshore large purse seiners can be demonstrated, and it is expected to raise awareness of a safer fishing environment and contribute to the reduction of accidents.

This study attempted to understand the meaning and nature of the drinking experience of participants participating in self-sufficiency program with alcohol problems. For this, data were collected by conducting in-depth interviews with seven problem drinkers currently participating in the self-support work project at the local self-support center. It was analyzed by a phenomenological analysis method. As a result of the study, 26 topics, 7 thematic vowels, and 3 categories were derived. The essential meaning of the study participant's drinking experience is as follows. It turned out to be 'a sense of accomplishment and belonging to job performance', 'extension of work life', 'maintaining social relations', 'weekly control drinking for self-support', 'minimum effort not to damage the working environment', 'self-criticism and reflection on absence from work resulting from heavy drinking', 'self-awareness of drinking problems. Through the analysis, the participants drank with a sense of accomplishment and a sense of belonging to job performance, and drinking was considered to extend their work life and maintain social relationships. At the same time, on weekdays when participating in self-support work projects, they we refrain from drinking in their own way and make minimal efforts not to interfere with the working environment under a hangover. The Absent from work due to heavy drinking led to self-reflection and furthermore, it was confirmed that they were aware of their problem drinking.

It's the situation that modern technological civilization shakes the life environment fundamentally without a serious reflection on the dangers. The sense of crisis' brought the rise of modern Ecology in awareness of survivability of the humanity. Because the serious reflection is not just a campaign for environmental protection, but is to establish the values which is possible to coexist and to make harmony between the nature and man, man and man, and to form a healthy relationship through philosophical thought and practice has intrinsic value for human and nature. Under these circumstances, if Yulgok lives now and he is questioned by the ecological theorists of the 21st century that "What do you think about the serious environmental problem of present times?", what really would be his explanation? In the presentation methods of the explanation, will question first what contents western ecologists who study Theory of the environment in technology, Deep Ecology, and Social Ecology propose, then will compare and introduce what similarities and differences from theirs. As a result, we'll be found that Yulgok's thought, moral consciousness, about the nature and humanity as a confucian scholar.

Because ships have limited support from land, it is necessary to equip them with automatic external defibrillators (AEDs) in preparation for the incidences of cardiac arrest patients and to properly place and manage AEDs. The seafarer must have the ability to use the AEDs. This is a study to identify the placement and management of AEDs in order to increase the utilization of AEDs in ships, analyze the ability of seafarers to use AEDs and their intention to use it, and suggest improvement plans. The study was conducted from September 9, 2019, to February 20, 2020, and a total of 244 ships and 244 seafarers were surveyed. The data were analyzed by the frequency, percentage, and chi-square test using SPSS WIN 23.0 program. As a result, most of the ships with one AED number were identified, and some ships with insufficient AED placement and management were also identified. A total of 142 seafarers (58.2 %) had experience in participating in AED education; 136 seafarers (55.7 %) had intention to use AEDs; and the most barrier factor was "I don't know how to use" (63.0 %). The intention to use AEDs was high among seafarers in the position of the captain, navigator, and deck department personnel, and when they had an experience in AED training and the training period was less than six months, they were active in using AEDs. In addition, efforts to raise an awareness and education of AEDs are required for occupational groups other than navigators who are not willing to use AEDs in ships, and it is necessary to review appropriate retraining cycles through an evaluation of the seafarer's ability to use AEDs.

The modern pentathlon is an exercise in which people and people compete, as well as exercise without equipment, exercise using equipment, and exercise with animals, and it is an exercise that includes static and dynamic exercise. The ethical issues of modern pentathlon athletes are also related to the poor environment and economic reasons, and the athlete's ethical awareness, attitude, and spirit have a great influence on the athlete's mental environment. In this study, the direction of improvement of ethical problems, which are different as important issues in modern sports, was examined, and qualitative research methods were applied to explore the sports spirit and ethics of the modern pentathlon. Correct sports should not deviate from the intended purpose of the exercise or cause or force the athlete to suffer physical or mental pain. In sports, compensatoryism can be a direct cause of improved performance or record-breaking, but sometimes it can also cause distorted athletes. Air doping has ethical issues that can cause controversy over the health or fairness of athletes, mental and physical damage to athletes, and harm. Responsibilities and ethical issues of athletes who take prohibited substances or leaders or supervisors who neglect or encourage them should be treated as very important matters. In the sports field, the reward system that is subordinate to the athlete's or leader's performance is related to the athlete's or leader's livelihood. For a fair and just game progression, it is necessary to break away from the development of athletes who are only focused on performance. The problem of Unethical issues must be overcome by emphasizing the restoration of ethics that are reasonably recognized in ideology and logic.

This study examines the efficiency of safety management measures taken in coastal waters to prevent coastal accidents. Recent years have witnessed about 800 cases of large and small coastal accidents in coastal waters annually. On average, these accidents have been responsible for 129 deaths annually, Thus, there is a need for effective preventive measures. Accordingly, the Korea Coast Guard enacted the Coastal Accident Prevention Act in 2014 and has cooperated with related organizations, such as local governments and the Ministry of Oceans and Fisheries, to safely manage coastal waters. However, compared to the rapid increase in human coastal activities, coastal accidents continue to occur due to the lack of a safety mindset among the Korea Coast Guard, a lack of public safety awareness, a lack of safety management facilities, and poor interest from related organizations, among others. This study examines the conditions and problems faced with regard to safety management in coastal waters based on recent coastal accident data, and analyzes foreign coastal waters safety management cases. Various methods to improve the safety management efficiency in coastal waters are proposed, such as enhancing the safety mindset and capabilities of the Korea Coast Guard, strengthening cooperation among related organizations, increasing the role of local governments, expanding and strengthening safety management facilities by applying new technologies, inculcating a culture of maritime safety, and activating private-public collaborative governance.

A national park is a place to conserve natural resources and visitors to experience nature, and thus, it is necessary to identify the noise distribution characteristic in the national park and preserve and restore the soundscape. However, most national parks in Korea are exposed to noise, leading to negative perceptions of the national park's soundscape and affecting the ecosystem. Many national parks in other countries have investigated the ecosystem impacts caused by noise and have performed various management to reduce the noise. However, in Korea, there is still a lack of awareness of the effect on the ecosystem, overlooking the need for soundscape management. Therefore, in this study, we developed a noise map of Mudeungsan National Park to investigate the quantitative impact of noise on visitors and the ecosystem. Also, we measured the trail's soundscape to describe a sound grade classification, and the soundscape of main spots in the park was recorded for a year and then analyzed. Finally, the sound resource distribution map was described, which can be used as preliminary data to determine the national park's sound distribution characteristics and manage the soundscape.

Collision prevention education, which takes up the longest time among officer training courses, is one of the most important training and practice courses for trainees. The purpose of this study is to investigate the trainees' perception of collision risk in order to develop a systematic and quantified collision prevention training course. For this, factors for judging collision risk were derived from previous studies, and each trainee's perspective on collision risk was derived for each scenario through a questionnaire survey for trainees. Using the PARK Model, the same was compared with the collision risk perceived by the officer. Resultingly, it was found that trainees and of icers consider the distance to other ships the most important among collision risk factors. Additionally, although the risk trends of two groups for each scenario were similar, the average risk of trainees (5.39) was higher than that of officers (5.20). However, the trainees perceived a lower level of risk than the officers in certain scenarios, and this is judged to be the result of the trainees' lack of navigational experience. This study is expected to be used as basic data for the development of collision prevention practice education by quantitatively suggesting the difference between the collision risk of trainees and officers respectively.
