The importance of resonable treatment of tide characteristics has been shown by Kweon, et al. (2005, 2006) for the crest elevation estimation because of a big difference of tidal elevation along Korean coast. For the procedure of crest elevation design, the expected overtopping probability (EOP) was estimated by Kweon, et al. (2006). The comparisons on each sea showed that EOP was lower east, south and west sea in order. The results involved the assumption that the tide and design level wave height meet any time in a year. However, big waves mainly occur in summer or winter in Korean coast, the study focuses on the encounter probability of big waves and seasonal tide level. A theory of the encounter probability is not derived by the present study but it shows reasonable acceptability of the proposed scenario in which the expected overtopping probability could be an index for the crest elevation estimation in Korean coast. The calculation based on the scenario gives the possibility range for the crest elevation estimation which has no tendency of each sea along Korean peninsular. The range is within the expected overtopping probability of 1% in the whole coast of Korea.

With the emergence of a climate crisis, climate disasters have recently been clearly felt in Korea. In particular, the typhoon 'Hinnamno' in the summer of 2022 made many people feel a sense of crisis with its formidable power. In this situation, children are likely to suffer great damage even in small crises due to their lack of experience and ability to cope with disaster situations. In this paper, we introduce a disaster response learning application that supports children's disaster response training. Designed based on research results on situational learning theory and child disaster safety education, this system produces various episodes and trains them to encounter disaster situations. Children can participate in the episode by choosing options during the episode, which is reflected in the picture diary after the episode is completed. By providing information naturally in the picture diary, children can access how to cope with disaster situations. Through this system, children are expected to develop their judgment in disaster situations that they can encounter and have the ability to secure basic safety outside of adult help.

In The Turn of the Screw, the go'erness encounters with the apparitions that harrow her throughout the story: she sees a frightening male ghost that Mrs. Grose identifies as Peter Quint, deceased former 'alet of the children's uncle, who had pre'iously shared the charge of the children with the pre'ious go'erness, Miss Jessel. The appearance of the ghosts hails the go'erness and thereby forces her to be jarred out of the comfortable habits of indi'iduality and plunged into a negati'ity de'oid of the socio-normati'e directi'es and guarantees. Such an encounter shows the idea that consciousness is a plenum of existence e'ocati'e of human mind as a decentered pandemonium. For the go'erness in The Turn of the Screw, the foundation to force her to experience the uncanny, as an inconsistency in the symbolic order, is particular. Its particularity is absolute in the same way e'ery one of us dreams his or her world. It resists mediation and cannot be made part of a symbolic medium. Just as Lacan's conceptions of desire, feminine sexuality, 'Object a,' not-whole, sla'ery, mastery, self-deception, authenticity, and act of psychoanalysis help us understand our contradictory social reality, so does The Turn of the Screw help us make sense of the way the go'erness, as the being who is capable of raising the question of being, questions the idea of being. In conclusion, the particular way the go'erness dreams her world is e'ocati'e of an excessi'e being, an anatomical complement, and a particular experience, such as the go'erness's encounter with the ghosts testifies to a knowledge that escapes the knowledge of the speaking being.

T. S. Eliot attempted the combining of the liturgy of Anglican Church and a drama in Murder in the Cathedral (1935) and created a modern verse drama which comes most close to the regular tragedy like Greek tragedy today. Eliot chose the drama to deliver his religious insight because of its ritualistic origin and its potentiality to deliver a dramatic world which can contain a complete order. The central theme of this play is the martyrdom. The dramatic action of killing the archbishop Thomas Beckett in this play, however, is not treated as important event enough to be a dramatic climax. He is portrayed as a witness to the reality of God's will rather than a man who wills to give up his own life for any religious belief or cause. In Eliot, a martyr is nothing but "a witness" in its ancient sense. This paper purposes to review the language of this play. The various and new meters and rhythms of the language of this play function enough to bring its playwright to encounter 'the real audience' in 'a living theatre'. The interactions between different verbal models also play a big role to make this play a living theatre. Eliot found the poetry which crosses the various classes and levels of the tastes of audience is the most useful poetry. And the poetry of this play proves as the very thing which intensifies the theme of the play and gives the most powerful force to the play. Especially Eliot's poetry succeeds smost in the various and free meters of chorus, which makes Eliot the first playwright since Aeschylus, who could bring the chorus to undertake the function of extending the dramatic action of the play into the universal meaning. In the theatre the real audience identifies themselves with chorus. And the chorus leads the audience to respond to peace which passeth understanding beyond words and sounds of this play, which is the desired response in Eliot's conception of drama.

This study measured the present number of encounters and established the evaluation criterion for the allowable number of encounters in the Seoseokdae summit area (SSA) of Mudeungsan National Park to examine managerial conditions of the number of visitors to the Seoseokdae trail section (STS). Data were obtained from a questionnaire survey of 263 visitors to STS selected through convenient sampling during June 2019. The average number of encounters in SSA was 18.7. Most of the respondents (95.4%) encountered fewer than 30 other visitors. The average maximum number of simultaneous users (AMNSU, measured at 15-minute intervals) in SSA was 13.4 persons (range: 3~31 persons). The AMNSU by the hour was the highest with 21.0 persons at 13-14, followed by 19.8 persons at 11-12, 15.5 persons at 14-15, 15.3 persons at 12-13, 12.3 persons at 10-11, and 10.8 persons at 8-9. Acceptable encounter number (AEN) developed by long-question format (LQF) was 59.2 persons, and that by short-question format (SQF) was 55.1 persons. AEN of the respondents who preferred "near-nature experience" at 27.5 persons was fewer than those who preferred "resort/tourism area like experience" at 46.6 persons. The present number of encounters and AMNUS (range: 3~31 persons) in SSA were fewer than AENs derived from LQF (59.2 persons) and SQF (55.1 persons). Eighty-three percent of the respondents preferred "near-nature experience," while only 10.5% of the respondents preferred "resort/tourism area like experience." 78.4% of the respondents did not perceive that SSA was crowded. The absolute majority of the respondents (92.3%) answered higher personal AEN than the perceived encounter numbers (PEN). The gaps between the personal AEN and the PEN were negatively correlated with perceived crowding.

This study aims to examine the characteristics and meanings of the encounter between Malaysian migration policy and Korean retirement migration in contemporary Malaysia. For this purpose, I describe and analyze the features and implications of migration policy in Malaysia, and understand the cultural characteristics and meanings of migration policy, especially Malaysian migration policy in Malaysia, and examine and explore the characteristics and meanings of retirement migration, especially Korean retirement migration to Malaysia in contemporary Malaysia, in the socio-cultural context. The research outcomes of this study are followings. Firstly, because of the misunderstanding and misuse of MM2H(Malaysia My 2nd Home) program and Malaysian migration policy among Korean retirement migrants in contemporary Malaysia, Korean retirement migration in Malaysia cannot be regarded one of the appropiate and effective migration policy for Koreans. It has been utilized as an instrument of their children's education among Koreans in Malaysia. Secondly, in this regard, it has been increased the number of Koreans to return to Korea without any constructive results in their children's education and their successful retirement lives in Malaysia. It is noted to understand that Korean retirement migration to Malaysia is the movement and migration of the special forms of human migration or human exchange and cooperation in the socio-cultural context. The cultural characteristics and meanings of Korean retirement migration to Malaysia has been one of the important cultural phenomena between Korea and Malaysia in contemporary Malaysia. In this sense, it is expected that this study can be contributed to understand the cultural characteristics and meanings of the encounter and exchange between Malaysian migration policy and Korean retirement migration to Malaysia in contemporary Malaysia, and to enhance the exchange and cooperation between Korea and Malaysia through human exchange and migration, especially Korean retirement migration to Malaysia in contemporary Malaysia.

Generally, the underwater flight vehicle (UFV) depth control system operates with the following problems: it is a multi-input multi-output (MIMO) system because the UFV contains both pitch and depth angle variables as well as multiple control planes, it requires robustness because of the possibility that it may encounter uncertainties such as parameter variations and disturbances, it requires a continuous control input because the system that has reduced power consumption and acoustic noise is more practical, and further, it has the speed dependency of controller parameters because the control forces of control planes depend on the operating speed. To solve these problems, an adaptive fuzzy sliding mode controller (AFSMC), which is based on the decomposition method using expert knowledge in the UFV depth control and utilizes a fuzzy basis function expansion (FBFE) and a proportional integral augmented sliding signal, is proposed. To verify the performance of the AFSMC, UFV depth control is performed. Simulation results show that the AFSMC solves all problems experienced in the UFV depth control system online.

In dielectric waveguide analysis and synthesis, we often encounter an awkward task of solving the eigenvalue equation to find the value of propagation constant. Since the dispersion equation is an irrational equation, we cannot solve it directly. Taking advantage of approximated calculation, we attempt here to solve this irrational dispersion equation. A new type of eigenvalue equation, in which guide index is expressed as a function of frequency, has been developed. In practical optical waveguide designing and in calculating the propagation mode, this equation will be used more conveniently than the previous one. To expedite the design of the waveguide, we then solve the eigenvalue equation of a slab waveguide, which is sufficiently accurate for practical purpose.

We simulated a forest fire which was occurred in Yangyang area on 2005 and compared a results between two different weather conditions(real weather condition and mean weather condition since 1968) using FARSITE, which is a forest fire spread simulator for preventing and predicting fire in USDA. And, we researched a problem in the transition for introducing, so we serve the basic method for prevention and attacking fire. In the result, severe weather condition on 2005 effected a forest fire behavior. The rate of spread under real weather condition was about 4 times faster than mean weather condition. Damaged area was about 10 time than mean weather condition. Therefore, Climate change will make a more sever fire season. As we will encounter to need for accurate prediction in near future, it will be necessary to predict a forest fire linked with future wether and fuel condition.

Several methods with order higher than that of Newton methods which are of order 2 have been reported in literature for solving nonlinear equations. The focus of most of these methods was to economize on/minimize the number of function evaluations per iterations. We have demonstrated here that there are several computational pit-falls, such as the violation of fixed-point theorem, that one could encounter while using these methods. Further it was also shown that the overall computational complexity could be more in these high-order methods than that in the second-order Newton method.
