Distribution of zooplankton abundance was studied in the front zone in the East Sea in November, 1996, Averaged total abundance in the front zone was less than that in the nearby cold surface water areas but more than that in the nearby warm surface water areas. The number of taxa was the greatest in the upper layer of mixing. Abundance and the number of tun in the front zone were contributed by the cold water and the warm water, respectively. Inspite of the differences in sampling time (day vs night), the species composition and abundance distribution were similar at two sites within cold or warm water area, However, they were quite different at two sites in the front zone although the sampling time of the day was the same. from this, the history of mixing was believed to be the most important factor for the species composition and abundance distribution in the front zone. Zooplankton distribution in the study area was mainly controlled by the dominant cold water Copepod Species Metridia paoifica, the only taxon that showed significant diet vertical migration. Most other taxa showed no significant diel vortical migration, Seawater temperature also affected zooplankton distribution. Positive correlations in the warm area, weak negative correlations in the cold water area, and no significant correlation in the front zone were obtained in general between the seawater temperature and the abundances of the major taxa.

This study aims to discover the clue of the current modern postal system development by looking at the delivery patterns of Korean letters during the Joseon Dynasty. A letter is a text medium that the sender sends to a recipient by sending a message of news. The form and contents of the letter are influenced by the various surrounding factors and are adapted to circumstances. The study aims to clear up the method of delivery and the nature of the transmitter among the environmental factors which affects the format and contents of Korean letters. Depending on the public or private matters, the delivery method is divided into a public agency and a private messenger, or divided into one-phase delivery and the multi-phase delivery depending on whether or not a phase is divided into stages. It is also divided into a one-way and a round-transmission depending on whether or not it is round-switched. The transmitter is divided into a verbal communication, the letter and verbal communication, and the letter communication according to whether or not it is by verbal, and divided into the relational and the non-relational person according to the relationship with the sender. Also depending on whether the transmitter is exclusive or not, it is divided into the exclusive messenger and the messenger who deliver a letter incidentally while come and go. In the aspect of the delivery method, We can see the possibility of developing to a modern mail system through the public method, the multi-phase delivery, one-way delivery and in the aspect of the transmitter, we can see the possibility through the letter delivery, non-related transmitter, and the exclusive messenger.

We investigate the intraspecific morphological variations and geographical distributions from twelve populations (28 samples) of Orobanche coerulescens in Korea. Two main morphological types were detected, i.e., glabrous (G-type) and pilose (P-type), in the external morphology (stem, leaf, bract, calyx, and corolla). The G-type was found on Ulleung-do and Dok-do, and the P-type was observed on the coasts of South Korea, Jeju-do and Ulleung-do. The distinct difference in the morphological types and geographical distribution suggested the existence of two putative lineages with different distribution processes. O. coerulescens, distributed in very limited areas, was only identified as the G-type on Dok-do. Hence, conservation efforts should focus on protecting native habitats to conserve native species and the unique biogeographic significance of this species.

The inter­relationship of Korea southeast region community related to a mask dramas in depth. The Folk mask dramas are, for traditional community members to live well and enjoy cultural practices in society. Even if a mask drama would be performed in the 21st century, it would be the one of traditional society. It shows the life of traditional society and proposes the issue of traditional society. The thing is handed down well with technology of a mask drama assigned as intangible cultural asset. The Korea southeast region, Kyongsang Provinces, or Yeongnam area has been handed down several kind of mask dramas. These are Byeolsingut Talnori with religious, the Ogwangdae of wandering play team, the Ogwangdae of local residents, and the Dulnorum of local residents. The mask dramas of Korea southeast region are specified as intangible cultural asset, many traditional mask play were restored. The restoring is imitation. These things are difficult to assigned as the intangible cultural asset. But though it is the imitation of the mask dramas, it is culture phenomenon. So we need to make the fostering system.

This study was an entertainer who was in charge of female music in the Joseon Dynasty, but the existence of gisaengs, who were recognized as'sexual partners' of the four grandfathers, and the Joseon Dynasty, when their existence was possible. I tried to reveal the social characteristics of Therefore, the research is meaningful in that it attempted to reveal the relationship between the grandfather and the gisaeng from various perspectives, and that it is possible to confirm the various social roles of the gisaeng. In the Confucian society, female musicians were not allowed to participate in Naeyeon and Chinjamrye, where women were the main pillars, so not only could the girl's music survive until the end of the Joseon Dynasty, but it was enough to reveal the existence of a professional artist. The existence of gisaengs is not irrelevant to the social background of the Joseon Dynasty, and therefore, it is impossible to define the Joseon Dynasty with the holy morality of modern society. It is believed that 『catching green onions is expected to enhance the aspect of a gisaeng as a celebrity, based on the interpretation that it is viewed from the perspective of an entertainer possessing an extraordinary and noble spirit rather than portraying the gisaeng in an erotic standard.

On this study, we analyzed the movie With gods's narrative structure. This movie makes most people who has seen it feel deeply moved. We think that people can get deep feeling from a film at last after people who has seen the movie accept a context, story, and a message of the movie gladly. We focused on a special system in this movie With gods that can make give an ordinary message and big touch to people. Also we focused on every episodes of every space in a movie, and someone who moved freely between the spaces. A repetitive form and repetitive contents in a narrative become a special code itself -repetitiveness- for people and make them do auto-communication. Specifically, an information, the movie's repetitiveness, out of people become a special code for them, and then that make people bring memory and new information by themselves. Watching movie, people can look back up on life with every trial in the movie. In short, a repetitiveness and an auto-communication are a special system in the movie, that can make deeply touched.

This paper is a study of the beginning pattern of simseul argument in the 19th century, based on the letter written by Hanju(1818~1886) and Mangu(1837~ 1902). In the text, I analyzed the theoretical differences between Mangu and Hanju that inherited from the study of Jungjae, is to expand the scope of the dispute between the Hanju and Mangu which to provide the beginning pattern of simseul argument. By revealing the theoretical difference between Hanju and Mangu, in the opposite direction, the content of the simseul argument between the Hanju and Jungjae's developed could be clearer. In the Hanjujip, there are nine letters to Mangu, there are also three letters to the Mangujip. These letters show a certain difference in the learning of the two people. So the text focuses on the content of these letters and reveals their theoretical differences, eventually it is confirmed that their theoretical differences lead to the beginning pattern of simseul argument. In particular, interpretation of LiKi leads to interpretation of Sim. Sim interpretation centers on the interpretation of the Zhuxi's 'Ki of Jungsang' meaning, while Hanju emphasizes to see as Lee, Mangu emphasizes that as the sum of Liki. 'Ki of Jungsang' is an interpretation of Zhuxi' Sim, and in the end, interpretation of 'Ki of Jungsang' means interpretation of Sim. Thus, while Hanju tried to see of Li, Mangu wanted to see at the sum of LiKi. This is simseul argument between Hanju and Man-gu, which was unfolded in the extension of the 19th century's simseul argument of erection. Through their argument, they are going to use it as an opportunity to review details of how the debate started in the Toegye school.

This study applied the web crawling technique for extracting big data news on water quality accidents in the water supply system and presented the algorithm in a procedural way to obtain accurate water quality accident news. In addition, in the case of a large-scale water quality accident, development patterns such as accident recognition, accident spread, accident response, and accident resolution appear according to the occurrence of an accident. That is, the analysis of the development of water quality accidents through key keywords and sentiment analysis for each stage was carried out in detail based on case studies, and the meanings were analyzed and derived. The proposed methodology was applied to the larval accident period of Incheon Metropolitan City in 2020 and analyzed. As a result, in a situation where the disclosure of information that directly affects consumers, such as water quality accidents, is restricted, the tone of news articles and media reports about water quality accidents with long-term damage in the event of an accident and the degree of consumer pride clearly change over time. could check This suggests the need to prepare consumer-centered policies to increase consumer positivity, although rapid restoration of facilities is very important for the development of water quality accidents from the supplier's point of view.

This study was conducted to investigate the role of drinking pattern in the relationship of alcohol consumption by face-to-face interview in rural elderly(n=994) aged 60~64 in Dalsung County, April to September in 1996. Pattern of alcohol drinking included drinking status, alcohol drinking at the morning without breakfast, average drinks per day, frequency of drinks per month, quantity of alcohol drinking, kind of preferred alcoholic beverage and duration of alcohol drinking. Blood pressure was measured once in each subject using a portable automatic sphygmomanometer. Difference in means of systolic blood pressure, alcohol drinking status, alcohol drinking at the morning without breakfast, and kind of alcoholic beverage were statistically significant before adjusting covariates, but alcohol drinking status and alcohol drinking at the morning without breakfast were statistically significant after adjusting covariates. And difference in means of diastolic blood pressure, kinds of alcoholic beverage was statistically significant before adjusting covariates, but no variables was significant after adjusting covariates. Model I multiple regression for systolic blood pressure that included average drinks per day as the variable of drink pattern, age, educational attainment and, previous history of cardiovascular disease were statistically significant, and multiple regression for diastolic blood pressure, educational attainment, BMI, and previous history of cardiovascular disease were statistically significant. Model II multiple regression for systolic blood pressure that included drinking patterns variables except average drinks per day, previous history of cardiovascular disease were statistically significant. However, multiple regression for diastolic blood pressure, no variables were significant. So, inconsistent with prior research, a positive relationship was not found between average drinks per day and diastolic and systolic blood pressure. The effect of alcohol drinking patterns on blood pressure has public health as well as clinical relevance. The study should be replicated to determine the reliability of our findings.

It is important to identify geometries of fracture that act as a conduit of fluid flow for characterization of ground water flow in fractured rock. Fracture geometries control hydraulic conductivity and stream lines in a rock mass. However, we have difficulties to acquire whole geometric data of fractures in a field scale because of discontinuous distribution of outcrops and impossibility of continuous collecting of subsurface data. Therefore, it is needed to develop a method to describe whole feature of a target fracture geometry. This study suggests a new approach to develop a method to characterize on the whole feature of a target fracture geometry based on the Fourier transform. After sampling of specimens along a target fracture from borehole cores, effective frequencies among roughness components were selected by the Fourier transform on each specimen. Then, the selected effective frequencies were averaged on each frequency. Because the averaged spectrum includes all the frequency profiles of each specimen, it shows the representative components of the fracture roughness of the target fracture. The inverse Fourier transform is conducted to reconstruct an averaged whole roughness feature after low pass filtering. The reconstructed roughness feature also shows the representative roughness of the target subsurface fracture including the geometrical characteristics of each specimen. It also means that overall roughness feature by scaling up of a fracture. In order to identify the characteristics of permeability coefficients along the target fracture, fracture models were constructed based on the reconstructed roughness feature. The computation of permeability coefficient was performed by the homogenization analysis that can calculate accurate permeability coefficients with full consideration of fracture geometry. The results show a range between $10^{-4}{\;}and{\;}10^{-3}{\;}cm/sec$, indicating reasonable values of permeability coefficient along a large fracture. This approach will be effectively applied to the analysis of permeability characteristics along a large fracture as well as identification of the whole feature of a fracture in a field scale.
