Multi-valued decision making for transitional stochastic events was newly derived based on conditional probability of knowledge database which included experts'knowledge and experience. The proposed multi-valued decision making was successfully adopted to the determination of the five levels of the vigilance of a subject during the EEG (electroencephalogram) recording; awake stage (stage W), and sleep stages (stage REM (rapid eye movement), stage 1, stage 2, stage $\sfrac{3}{4}$). Innovative feature of the proposed method is that the algorithm of decision making can be constructed only by use of the knowledge database, inspected by experts. The proposed multi-valued decision making with a mathematical background of the probability can also be applicable widely, in industries and in other medical fields for purposes of the multi-valued decision making.

The purpose of this study is to find out the stress causes of the primary students in Korea, through the three major methods, life event score, multiple regression about stress causes and G.H.Q. path-diagram. A survey was made of 889 students who were selected among students of six primary schools in seoul and Ka-pyeng, from Sep. 28 to Oct. 2. 1992. The results of this study are summarized as follows : 1. Life event score Among the children's life events, (deaths of family) (degrade of school record) (the increase of absence days) (divorce of parents) (trouble with relationship) are high ranking in life event score. Besides, (scolded by teacher and parents) (beginning of extracurricular work) are spread stress causes. In conclusion, these stress causes are shown by two aspects, home, school, and so children are under stress circumstance in both places. These stress causes vary with area and sex. 2. Multiple regression about stress causes and G.H.Q. This study analysed how a stress caused by home life affects the children's health of mind and body. The most influential factors are , and these factors vary with area and sex. 3. Path-diagram This study proved that socio-psychological school environment raises children to secede from school, and this secession that operates as a stress cause affects children's health of mind and body. This serial process is analysed by path analysis, and made out a path-diagram. In conclusion, as expected socio-psychological,school environment affects the children's health of mind and body. This is shown by two aspects : positive, negative. This stress causes vary with area and sex.

Disaster of Sewol took place in one year. Meanwhile, the victim's family and the call time record academics have tried to record it. Ansan activists have moved to objectives such as civil records committee also pivotal. The citizens committee under the dictation recording oral history team has a diverse group of people associated with the time issue. bereaved families were collected from the oral as well as volunteers, religious personnel, activists, Ansan citizens and various people. Disasters around the world is also an important event to remember and honor the people together, and one of the most effective means to record There it is establishing an oral history archive. Does not leave a lot of nature history of sudden disasters that occur, as well as a tribute record dictation telling people of diverse perspectives on events helps a lot closer to the reality of the event. Erected in the National September 11 Memorial Museum to honor the Sept. 11 attacks and provide a variety of programs to chaerok dictation of the people involved with 9/11. To remember the 2013 Boston Marathon bombing 'Our Marathon' of crowdsourcing digital archive was built. In the archives of the local universities and institutions were created to collaborate actively and gathering oral history. Pan Am Flight 103 pieces terror has established an archive from Syracuse University. Here, neither graduates, faculty, and to the victim's family and friends gather and oral hitory. Disaster-related Sewol neither should be able to be used as in the case of foreign well, and it should continue to honor the victims of the collection. It also ought to occasion again to avoid this disaster on earth.

In recent years, Personal Health Record (PHR) has emerged as a patient-centric model of health information exchange. The Personal Health Record (PHR) owners enjoy the full right of accessing their records anywhere and anytime making storage and retrieval more efficient. Due to the sensitivity and confidential nature of the PHR, however, the PHR is maintained in a secure and private environment with the individual determining rights of access. In this paper, we propose a system which enables access to the user's PHR in the event of emergency. In emergency situation where the user is unconscious, the emergency staff can use the PHR information to request a emergency access to the PHR server based on the predefined rights of access for PHR. Under the proposed system, the PHR owner can specify a fine grain access control policy during emergency situations.

A record-breaking high surface air temperature of 41.0℃ was observed on 1 August 2018 at Hongcheon, South Korea. In this study, to quantitatively determine the formation mechanism of this extremely high surface air temperature, particularly considering the contributions of the foehn and the foehnlike wind, observational data from Korea Meteorological Administration (KMA) and the Weather Research and Forecasting (WRF) model were utilized. In the backward trajectory analysis, trajectories of 100 air parcels were released from the surface over Hongcheon at 1600 LST on 1 August 2018. Among them, the 47 trajectories (38 trajectories) are tracked back above (below) heights of 1.4 km above mean sea level at 0900 LST 31 July 2018 and are defined as upper (lower) routes. Lagrangian energy budget analysis shows that for the upper routes, adiabatic heating (11.886 × 10³ J kg^-1) accounts for about 77% of the increase in the thermal energy transfer to the air parcels, while the rest (23%) is diabatic heating (3.650 × 10³ J kg^-1). On the other hand, for the lower routes, adiabatic heating (6.111 × 10³ J kg^-1) accounts for about 49% of the increase, the rest (51%) being diabatic heating (6.295 × 10³ J kg^-1). Even though the contribution of the diabatic heating to the increase in the air temperature rather varies according to the routes, the contribution of the diabatic heating should be considered. The diabatic heating is caused by direct heating associated with surface sensible heat flux and heating associated with the turbulent mixing. This mechanism is the Type 4 foehn described in Takane and Kusaka (2011). It is concluded that Type 4 foehn wind occurs and plays an important role in the extreme event on 1 August 2018.

Frequently faced with dangerous situations, for evidentiary purpose in case of civil and criminal liability challenges, car drivers in Korea have been armed with so-called 'black boxes'; however, which are just video recorders in vehicles rather than real 'black boxes' that are equipped in the airplanes. In the United States, they are called EDRs(Event Data Recorders), more technically, which means that they record data of events happened while driving, such as velocity changes, airbags deployment, seatbelt wearing etc. just like in the airplanes. EDR technology is quickly becoming more advanced, more widely available, and less expensive; however, new concerns are emerging : the privacy of drivers. In U. S., vehicle manufacturers and insurance companies and the governmental agencies including the courts and legislatures are the main parties in terms of the EDR concerns. In order to determine the best way to regulate EDR, it is necessary to balance all the merits, such as safety, privacy, truth, justice and efficiency, to support a legal framework regulating the EDR concerns. This article, in light of the regulation of EDR and experience therof in the United States, examines EDR technology itself, particularly with respect to the automobile industry, describing its history, its current state, and trends that may change it in the future; and explains how the National Highway Transportation Safety Agency (NHTSA), legislatures, courts have approached EDR data. At the early stage of regulation on EDRs in Korea, examining U. S. legal framework and usages would help for successful establishment of legislation and regulation.

The attitude of observer in the painting of history is to exclude a prejudice and a subjective view of an artist and to introduce a photograph, which is a record of objectivity, in the process of painting. Its ultimate intent is to redescribe the fact of an event's image intactly without any prejudice and to represent the event as a proven evidence that it was. The representation of history based on fact had already been conceived in imagination of renowned artists such as Francisco Goya or $Th{\acute{e}}odore$ $G{\acute{e}}ricault$ even before cameras were invented. What they portrayed was their own truth of reality which is gained through their observation, not a history that have corresponded to political ideologies, for all reliance on a limited tool of representation, painting. Furthermore, history was necessary for 19th century impressionism artists to be represented under proven fact in a neutral perspective excluding all subjective prejudice, not based on the representation with imagination. Edouard Manet in particular reconstited an instant moment on the basis of real proof of photograph without personal prejudice or opinion as if today's photojournalism. The catastrophic series by Andy Warhol and the photographic painting by Gerhard Richter show another role of painting in the realm of art, each of them implying information distortion and abuse by current media and intentional deformation toward history as Manet's painting of history. Today, the representation of an historical event that we experience in the era of the Internet and social networks having a great deal of information already came to be the exclusive property of the cutting edge mass media. Nevertheless, the attitude of observer which is realistic and contemplative in the realm of art is the crucial point in terms of artists' act as ever.

The Donghak Peasant Revolution in 1894 was a nationwide movement from the bottom of the uprising, which opened Korean modernization. Before and after the said revolution, the map of East Asian powers changed. It was an event with very significant meaning. When the revolution occurred in 1894, the peasant revolutionaries could not escape from the yoke of the traitors who rebelled. However, as time passed, recognition of the event also changed. Since the centennial anniversary of the Donghak Peasant Revolution in 1994, concerns and interests regarding the event have increased. Studies on this revolution have also been invigorated, thus shedding new light on the incident. By focusing on the historical sources on the Donghak Peasant Revolution in this article, the current status and archive of the event is studied, its value reviewed, and its collection, classification, arrangement, and description discussed from the perspective of archival studies.

This study is performed to find out the eruptive events of the historical period recorded in literature, which have been recognized and regarded as ones from Mt. Baekdusan, and to make volcanological interpretations of the eruptive events. Since the Millennium eruption, more than 31 eruptive events have been discovered, most of which are Plinian eruptions with volcanic ash that dispersed into the regions in the vicinity of the volcano. The 1903 record includes the event of the phreatomagmatic or vulcanian eruption that occurred within the Cheonji caldera lake. Based on the eruption records of the historical period and the 2002 precursor unrest to volcanic eruptions, Mt. Baekdusan has been evaluated and regarded as an active volcano that has the potential to erupt in the future.
