Since insects play important roles in existence of plants and other animals in the natural environment, they are considered as necessary biological resources from the perspectives of those biodiversity conservation and national utilization strategy. For the conservation and utilization of insect species, an observational learning environment is needed for non-experts such as citizens and students to take interest in insects in the natural ecosystem. The insect identification is a main factor for the observational learning. A current time-consuming search method by insect classification is inefficient because it needs much time for the non-experts who lack insect knowledge to identify insect species. To solve this problem, we proposed an smart phone-based insect identification inference system that helps the non-experts identify insect species from observational characteristics in the natural environment. This system is based on the similarity between the observational information by an observer and the biological insect characteristics. For this system, we classified the observational characteristics of insects into 27 elements according to order, family, and species, and proposed similarity indexes to search similar insects. In addition, we developed an insect identification inference prototype system to show this study's viability and performed comparison experimentation between our system and a general insect classification search method. As the results, we showed that our system is more effective in identifying insect species and it can be more efficient in search time.

Modern society is diversified society and is under complicated situation as the boundary of each area has been disappeared. To understand and accept such complicated situation as widely as possible, it is required to understand interaction. of receiver with intertextual environmental arts as the structure of open text. This study examined interaction of environmental arts in terms of intertextual feature based on experience of receiver on combined element of different space and time, combination of genres. This is the concept of meaning personal experience or situation as receiver participates the process of completing art works, and set the fantasy, post-place and speciality of location and temporal-spatial expression method, as characteristics of intertextuality. Features of such experience elements are used as methodology of analyzing characteristics of each work. Feature of fantasy uses strategy of inducing spatial experience of receiver with dematerialization for post-place and expands the place where events occur with intervention of contingency and event situation. It suggests the spatial-temporal expression method as the features focusing on process and reflecting changes in spatial-temporal continuum and speciality of place emphasizing context of place. In conclusion, environmental arts needs to be deep rooted on complicated existence aspect of receiver beyond metaphysical dimension depending on presence and to accomplish conversion of awareness of supplying bisection of life from that place. By doing so, environmental arts can live textual life as it gets together with all other texts in terms of text dimension and creativity can be reborn as practical creativity in intertextuality rather than uniqueness. Such combination with other areas and acceptance of various aspects of receivers who see and experience this will result to creation of open works which can be create newly over and over again in multi-dimensional aspects.

In a wireless multicasting when a mobile host moves to the new bate station being in the same multicast group it needs to exchange information about data delivery between base stations to receive data from the new base station at once. However it is inefficient to use the existence schemes because it takes too much time to exchange information and many overheads. The next, a mobile host moving to the base station not being in the same multicast group, the old base station will pre-forward data to neighboring base stations to avoid transmission delay. However, if other mobile hosts move at short interval, the old base station may retransmit the same data to the same neighboring base stations. In this paper we proposed called Information Exchange Scheme (IES). In IES in the same multicast grope the base stations exchange information locally so it takes the minimum time and overheads to use IES. Also in IES the neighboring base stations delay to delete data for continuous moving of other MHs. We also present how our scheme is efficient by producing cost ad simulating.

The purpose of this study is to propose actual operation condition of Japanese lecture based on social welfare organizations located in Seoul to investigate the current status and problems of Japanese language education in terms of lifelong education. According to the result of this study, the remarkable point was that a majority of Japanese lecture courses are highly focused on the elderly and 86% of the welfare organizations are providing free education. Regarding the effect of specialized business for the aged run by social welfare community center, it says, as Korea changing to aging society at the beginning of 21st century, it has put focus on strengthening personal competences of seniors through opportunities for participation in lifelong education, recreational activity programs and culture classes. It means foreign language classes are operating as one of the lifelong education programs for reinforcement of individual capability. Considering this tendency, it is expected that the lifelong education participation rate of the elder in Seoul will be raised. So, systematic improvements will be needed for this. First, it is required to recognize the existence of Educational and Cultural Industry and work hard to make it public so it could be invigorated and utilized by people usefully at the same time. Second, Japanese language training that mostly 55-year-old or more than 60-year-old people receive at the welfare center needs to be systematized for preparations on proper studying environment which provides the older with appropriate education method and content as well. Third, stable and systematic operation should be available through the link with experts in the field of Japanese language education and elderly education. Fourth, education program development is needed, which is able to satisfy one's desires for learning. Hence, targeting Japanese learners at each welfare center, we need to know the estimation of satisfaction degree and consciousness on learning Japanese. Finally, it has not been studied sufficiently regarding the instructors on teaching Japanese language in this paper, but it has been reported that most of social welfare centers, where Japanese language lectures are provided, are run by volunteers who can teach Japanese. Thus, the study on actual condition for Japanese language instructors will be conducted as well later on.

The Korean Mask-Dance Theatre has been developed closely related to Korean Shaman rituals. As many scholars noticed, the performers of the Mask-Dance Theatre were closely related to the Shaman family. In addition, there are mask-dance performances in actual shaman rituals. and are the representative performances among them. This essay intends to compare these two mask-dance performances in the shaman rituals to the similar performance of Old Grandpa and Grandma episode in the regional Mask-Dance Theatre. This study would bring us further in proving the close relation between the shaman ritual and the Mask-Dance Theatre. is one episode, Keori, in the shaman ritual of 'Baeyeonsin-kut' and 'Taedong-kut' in the mid-west seashore area. 'Taedong-kut' is the village shaman ritual for fertility and prosperity, while 'Baeyeonsin-kut' is a private shaman ritual for a large catch of the ship. is held in the later part of the whole shaman ritual since the later part tend to be more for entertainment than actual ritual. The story of is very similar that of in Pongsan Mask-Dance Theatre of the mid-west region. In addition, some of their dialogues are very similar. Only the later part is different. These similarities indicate that the Mask-Dance Theatre, which came into being in later period than the shaman ritual, has likely taken the story motif of the shaman ritual. is also a performance in the shaman ritual of east coasts. is more elaborate and recreational than of the west coasts. is also performed near the end of the ritual, and sometimes it is not performed at all. This indicates that has little ritual meaning left. When we compare it with the regional Mask-Dance Theatres such as Keosung Okwangdae, Tongyong Okwangdae, and Suyong Yaryu, the structure and the story lines are also very similar. It is a question why only the motif of the Grandpa and Grandma isfound both in the shaman ritual and the Mask-Dance Theatre. Many other motifs of other episodes in the Mask-Dance Theatre are not found in the shaman rituals. It seems that the Grandpa and Grandma motif is related to the ur-belief in fertility. In other words, this motif seems to be originated from the old belief in the fertility couple of Chonha Taechanggun and Jiha Yeochanggun. The shaman ritual for fertility first picked up this motif, and then the mask-dance theatre also adapted this motif for its recreational purpose. When we compare with , still has more aspects of fertility ritual, while lost its ritualistic meaning and its main purpose is to develop dramatic needs. and are invaluable existent performances to prove theatre's origin in ritual. The existence of mask-dance performances in the shaman rituals shows us the transit performance between theatre and ritual.

This exploratory study investigated the effects of the interaction between the experience of social exclusion and the presence or absence of a companion animal on the psychological well-being of individuals. Participants answered questions about whether or not they were respected by the community (yes or no); whether or not they currently have a companion animal (yes or no); and if they do, what kind of animal(s) they raise (multiple answers allowed). The study also assessed the psychological well-being of the participants. The group that experienced social exclusion demonstrated lower levels of psychological well-being than the group that did not. In addition, the group that reported the presence of at least one companion animal evinced higher levels of psychological well-being than the group that did not. Individuals who experienced social exclusion but lived with at least one companion animal were found to display superior psychological well-being than those who could not avail of the company of an animal. No difference in psychological well-being was found between those with a companion animal and those without one in the group that did not experience social exclusion. In conclusion, this study observed the effects of the binary interactions between social exclusion (experienced vs. not experienced) and the existence of companion animals (presence vs. absence) on the psychological well-being of people. The empirical data offer theoretical implications for the conditions in which companion animals do or do not improve psychological well-being in humans.

This study investigated the application and satisfaction of the global industrial technology curriculum for foreign students at J University in Korea. In order to derive the global industrial technology curriculum, industry needs were analyzed, and the appropriateness of the curriculum was identified through the current status of the root industry. In order to investigate the satisfaction with the application of the global industrial technology curriculum, a questionnaire survey was conducted in the form of an in-person interview for two months from August to September 2021 for foreign students. The questionnaire surveys included general information of the subjects, the status of completion of the curriculum, questions about class satisfaction, the process of obtaining certifications, and whether or not they were employed. As a result of the study, the reasons for choosing the curriculum of the respondents were their interest in subjects related to the root industry (welding, machining, etc.) and the issuance of Korean employment and visas (E-7). The most preferred subject was welding practice at 36.8%, and in terms of subjects considered necessary, the subject of basic major terminology was the most at 29.2%. The difference in satisfaction between graduates and current students who applied the same curriculum was tested, and as a result of the analysis, it was confirmed that there was no difference in satisfaction between current students and graduates through the t test (significance level p=0.05). We believe that this study is meaningful in that it provides basic data for the domestic industrial technology curriculum for foreign students and suggests the direction of related research in a time when the existence of universities is threatened due to the decrease in the school-age population.

When acquiring a product having an OS, it is very important to identify the exact kernel version of the OS. This is because the product's administrator needs to keep checking whether a new vulnerability is found in the kernel version. Also, if there is an acquisition requirement for exclusion or inclusion of a specific kernel version, the kernel identification becomes critical to the acquisition decision. In the case of the Linux kernel used in various equipment, sometimes it becomes difficult to pinpoint the device's exact version. The reason is that many manufacturers often modify the kernel to produce their own firmware optimized for their device. Furthermore, if a kernel patch is applied to the modified kernel, it will be very different from its base kernel. Therefore, it is hard to identify the Linux kernel accurately by simple methods such as a specific file existence test. In this paper, we propose a static method to classify a specific kernel version by analyzing function names stored in the symbol table. In an experiment with 100 Linux devices, we correctly identified the Linux kernel version with 99% accuracy.

The article identifies and theoretically substantiates the trends of national resilience in the context of establishing the security of the country and its civilizational subjectivity. The strategy of development of the pedagogical university in the conditions of European integration into the European educational and scientific space based on certain characterological features of the personality of the volunteer in the context of allocation of personal resilience is developed. The analysis of both external and internal challenges and threats to the civilization of the country needs to be understood in the context of economic, socio-political, legal, military-political, spiritual-cultural, educational-scientific and network-information resilience. The concepts of "national resilience" and "national security" are quite close - at first glance, even identical. However, a deeper understanding clarifies the differences: national security is a state of protection of the country identity and its very existence, the realization of its national interests. In turn, resilience is a fairly effective strategy and a fundamental guarantee of national security. At the same time, it is extremely important to understand that both national security as a state and national resilience as a strategy are only means of achieving and developing a strong and humanistic civilizational subjectivity of the country. After all, such subjectivity opens for citizens the opportunity for development, dignified self-realization and a proper life. The restructuring of the volunteer's motivational sphere is due to the dominance of such leading motives, which are focused mainly on maintaining and restoring health, which leads to distorted meaningful life goals: isolation, alienation, passivity, inertia, reduced activity, limited communication, etc. The characteristics of relatively stable human behavior include several primary and secondary properties. The primary (relevant) properties include patience, trust, hope, faith, confidence, determination, perseverance, and love; the secondary - punctuality, neatness, obedience, honesty, loyalty, justice, diligence, thrift, accuracy, conscientiousness, obligation, etc. The restructuring of the volunteer's motivational sphere is due to the dominance of such leading motives, which are focused mainly on maintaining and restoring health, which leads to distorted meaningful life goals: isolation, alienation, passivity, inertia, reduced activity, limited communication, etc. The characteristics of relatively stable human behavior include several primary and secondary properties.

Directly to the personal traits of resilience should be included methodological competencies, which include methodological knowledge, skills and abilities (ability to define ultimate and intermediate goals, plan, conduct and analyze knowledge, establish and implement interdisciplinary links with disciplines of medical-psychological-pedagogical cycles, etc.). All these competencies form the professional resilience of the volunteer.

Daesoonjinrihoe perceives that human suffering is caused not only by mental factors but also by the cosmic principle of Mutual Overcoming more fundamentally. The relationship influenced among all things in the universe is Mutual Beneficence and Mutual Overcoming. If these relations are properly cooperated in harmony, all things will reveal their energetic existence in a balanced state, however, if one side, particularly, Mutual Overcoming becomes excessive, indeed, it will cause trouble. That is, the sentient beings that are inclined to excessive Mutual Overcoming rather than indispensable Mutual Overcoming make grievances among themselves and cumulate them. In the end, heaven and earth lose its constant Way[常道], leading the sentient beings to all kinds of agonies. However, it may be a problem if every agony is depicted with Mutual Overcoming, that is, one single fixed frame, because Mutual Overcoming has to be interpreted diversely according to the circumstances. Thus, it is not possible to explain precisely about the agony if not understanding its spectrum. This study analyzed the ways how Daesoonjinrihoe explains the aspects of reasons and solutions to a variety of agonies. In the Supreme Scripture of Daesoonjinrihoe, the reasons for agony vary: first, it is caused by Mutual Overcoming of the cosmos itself, which is irrelevant to human beings. Secondly, man can be victimized because of Mutual Overcoming caused by man. Thirdly, there is a case of a victim who is damaged due to Mutual Overcoming caused by the other. Fourthly, man can be victimized because of Mutual Overcoming caused by someone else's unintended deeds. Fifthly, there is a case of man having agony in return when he, as a perpetrator, hurt others or resolve his inappropriate desires. Sixthly, man's deed unintendedly became a sin and have agony in return. Seventhly, man can be a self-perpetrator, conceiving vain desire, obsession and grievance. Eightly, there is a case of man having agony during enforcement of the law or practice of justice. Ninthly, man needs to endure agony during self-cultivation, enacting Reordering of the Universe(天地公事), ritual practice, promotion of fortune, and test. However, it is important to make sure that the reason for agony can interact with not only one but also diverse models in real situation. These nine models are included in the category of Mutual Overcoming; but, these cannot be classified in a single term, Mutual Overcoming because much information will be hidden, only to make it difficult to explain about agony more precisely. There are some characteristic observed in the concept of agony in Daesoonjinrihoe as follows: first, reasons for agony are caused by Mutual Overcoming although Mutual Overcoming can be interpreted differently according to the circumstances. Secondly, Daesoonjinrihoe makes a positive valuation for some agony. Thirdly, the solution to overcome a agony is brought to a conclusion, that is cultivation practice of Daesoonjinrihoe. Fourthly, the experience of agony and solution in Daesoonjinrihoe sometimes lie in the unit of family beyond individual. Fifthly, in the painful situation resulted from vain desire and obsession, Daesoonjinrihoe suggests a solution called Mutual Beneficence. That is, it emphasizes not only self-control but also active practice of considering others.
