Malaria is estimated to have a worldwide incidence of more than 100 million clinical cases and approximately 1 miuion deaths per year. Korea, although previously tnlown as an endemic area of tertian malaria (Pzosmonin vivax), has been considered free from malaria as there had been no report on indigenous cases since 1984. Recently, however, we experienced an indigenous case of P. viuax infection in a young man who had never been abroad. The patient was a 23-year-old Korean soldier with 18-day history of recurrent fever and chill lasting 4 to 8 hours on alternative days since mid-July 1993. He had lived in Changwon, Hyongsangnam-do, before entering barracks located in Paiu-gun, Kyonggj-do on Jne 1992, and had never been out of Korea. He had no history of blood transfusion nor parenteral use of drugs. The peripheral blood smears showed typical ring forms, trophozoites, and gametocytes of p. uiuox, in addition to mild anemia and thrombocytopenia. After confirmation of the diagnosis, he was treated with hydroxychloroquine and primaquine. Follow-up blood smears no more revealed malaria parasites. It is not certain whether the present case is due to a resurgence of indigenous malaria or a secondary infection from introduced mnuia. Whichever the source of infection the domestic occurrence of mnuia cycle in Korea should be a warning sign in public health point of view.

Background : Cervix cancer is the most common form of cancer among Korea women. in spite of proof that cervical cancer screening could reduce death rates substantially, the screening rates reported by previous Korean studies remain stubbornly very low. Behavioral studies to increase the cervix cancer screening rate are essential in order to develop the cancer screening program. Objective : To evaluate the factors which are related to the intention and behavior for cervix cancer screening using the Theory of Planned Behavior (TPB) and the Theory of Reasoned Action (TRA). Methods : The survey was conducted from July 21 st to 26th in 1998. Of 3,218 women, 303(12.2%) between 30 and 55 years old, voluntarily participated in the survey in the 3 Myeons in Choongju city. Charge-free cervix cancer screening was provided for the subjects 3 months later. Results : The R-square of both TPB and TRA to the intention (30% and 42%, respectively) was greater than the actual behavior (21% and 13%, respectively. TPB and TRA were found to provide an appropriate framework for the study of cervix cancer screening behavior. However, TRA was more powerful in explaining the intention, not only because the perceived behavioral control component exhibited lower reliability and validity than other components(altitude and subjective norm), but also because there may have been a few limitations in this study design. Consequently, the use of TRA is preferred in attempting to explain intention and actual behavior in this study. Conclusions : This study suggests that a successful intervention program should focus on changing attitudes and reducing psychologic barriers, rather than on just providing information. Physician recommendations, and the support of family members and friends are also very important factors in cervix cancer program participation. Physicians, friends, family members, and opinion leaders in rural areas, all of whom could affect the individual subjective norm, may all have the potential to play great roles as facilitators.

This study confirmed that a doctor named Lee, Seok-gan whose name has been widely known but whose real identity has remained unclear, was an active Confucian doctor in the 16th century. In addition, through the newly discovered "Daeyakbu" among his family line, writings, and relics that have been handed down in a family, this study looked into his medical philosophy and medicine culture. The author of "Ieseokgangyeongheombang"(Medical Book by Lee, Seok-gan(李石澗), Seok-gan is the same person as an active famous doctor Lee, Seok-gan(李碩幹, 1509-1574) in the 16th century. Such a fact can be confirmed through "Samuiilheombang", "Sauigyeongheombang" and the newly opened "Ieseokgangyeongheombang". Lee, Seok-gan was born in the 4th ruling year of king Jungjong (1509) and was active as a doctor until the 7th ruling year of king Seonjo(1547); his first name is Jungim with the pen name-Chodang, and he used a doctor name of 'Seokgan.' He was known as a divine doctor, and there have been left lots of anecdotes in relation with Lee, Seok-gan. Legend has it that Seokgan went to China to give treatment to the empress, and a heavenly peach pattern drinking cup and a house, which the emperor bestowed on Seokgan in return for his great services, still have remained up to the present. Usually, Seokgan interacted with Toegye Lee Hwang and his literary persons, and with his excellent medical skills, Seokgan once gave treatment to Toegye at the time of his death free of charge. His medical skills have been handed down in his family, and his descendant Lee, Ui-tae(around 1700) compiled a medical book titled "Gyeongheombangwhipyeon(經驗方彙編)". Out of Lee, Seok-gan's keepsakes which were donated to Sosu museums by his descendant family, 4 sorts of 'Gwabu'(writings of fruit trees) including "Daeyakbu" were discovered. It's rare to find a literary work left by a medical figure like this, so these discoveries have a deep meaning even from a medicine culture level. Particularly, "Daeyakbu" includes the typical "Uigukron". The "Uigukron", which develops its story by contrasting politics with medicine, has a unique writing style as one of the representative explanatory methods of scholars' position during the Joseon Dynasty; in addition, the distinctive feature of "Uigukron" is that it was created in the form of 'Gabu' other than a prose.

The accurate geo-referencing processes that apply ground control points is prerequisite for effective end use of HRSI (High-resolution satellite imagery). Since the conventional control point acquisition by human operator takes long time, demands for the automated matching to existing reference data has been increasing its popularity. Among many options of reference data, the airborne LiDAR (Light Detection And Ranging) data shows high potential due to its high spatial resolution and vertical accuracy. Additionally, it is in the form of 3-dimensional point cloud free from the relief displacement. Recently, a new matching method between LiDAR data and HRSI was proposed that is based on the image projection of whole LiDAR data into HRSI domain, however, importing and processing the large amount of LiDAR data considered as time-consuming. Therefore, we wmotivated to ere propose a local LiDAR chip generation for the HRSI geo-referencing. In the procedure, a LiDAR point cloud was rasterized into an ortho image with the digital elevation model. After then, we selected local areas, which of containing meaningful amount of edge information to create LiDAR chips of small data size. We tested the LiDAR chips for fully-automated geo-referencing with Kompsat-2 and Kompsat-3 data. Finally, the experimental results showed one-pixel level of mean accuracy.

The following summarized argument is the comparative research of the characteristics of automatic techniques demonstrated in the mixed expression of foreign language and Korean language in Lee Sang's poetry. Our research examines the use of foreign languages such as French and English shown in Lee Sang's poems, and then, recognized the characteristics of the automatic techniques demonstrated by the parallel marks and signs of Korean language. The automatical technique's element that Lee Sang made use of is a language of loanblend, consisting of free use of French, English, Japanese and Korean. The mathematical and geometric figures such as numbers and shapes can be seen as an important poetic language. In Lee Sang's poetry, the French words "AMOUREUSES" and "ESQUISSE" and English words "I WED A TOY BRIDE" are considered as parts of Korean language. The use of foreign language is seen by the readers as encodes of a unacquainted language and it provides rhetorical characteritstics that gives off profanatory feeling about the poetry. The poet is seen to have created a new poetic language that excess the standards of the limitations that Korean and Chinese marks have through the application of polysems and poliphonyic effects that foreign languages have. The mathematical and geometric signs are Lee Sang's special experimental elements that can't be seen in other literary poetries. They are conversational and the requirements for the expression of abstract artistry and esthetics. The language used in his poetry are external to those traditional poetic languages and they mix freely with other poetic elements to become an automatic technique used in the writing. Lee Sang's techniques can be considered as the pursuit of defiance and departure, freedom about literature and artistry. Moreover, the avant-garde expressionism is the literary form that demonstrated the sense of inferiority, nervousness and loneliness risen from physical pain and the abnormal relationship with women in the poet's personal life. The technique shows the longingness of the the Western culture and literature that lay dormant in the poet's consciousness and it is also the expression of ingenious that created the new guide in the Korean poetic literature, exceeding the European surrealism. Lastly, the automatic technique images that are demonstrated by the mixture of the foreign languages and Korean language are the creations of an innate poetic language and poetic literature that can't be imitated by anyone in Korean literature.

Converter steel slag(BOF slag) is a vast amount of solid waste generated in the steelmaking process which has very low utilization rate in Korea. Due to the presence of free CaO which can derive bad volume stability in BOF slag, it usually land filled. For recycling BOF and identify its applicability as fine aggregate, this study investigates the fundamental characteristics of mortar with cement replaced ferronickel slag(FNS), which has the potential to be used as a binder. The results suggest that the mineral phases of BOF slag mainly include larnite(CaSiO₄), mayenite(Ca₁₂Al₁₄O₃₃) and wuestite(FeO) while olivine crystallines are shown in FNS. The results of flow and setting time reveals that the flowability and process of hardening increased when the amount of FNS and BOF slag incorporated was increased. The length change shows that the amount of change in the length of the mortar was almost constant regardless of mix proportion while compressive strength was reduced. Micro structure test results revealed that FNS or/and BOF slag mix took a long time to react in the cement matrix to form a complete hydration products. To achieve the efficient utilization of B OF slag as construction materials, proper replacement rate is necessary.

This article is a study of Karl Marx's manifesto and the reform in donghak for the modality and their symbolism. As a text, Karl Marx and Friedrich Engels' declaration on the Communist Alliance and the reform program of the peasant Donghak were choose. This Declaration and the Reformation are the works of philosophical practice discourse of the 1800s in this article, which unfolds paradigmatically, deriving its common symbolic meaning in the semiotic sense, and evolving ideologically towards a democracy free of property. In the end, these two historical incident which are published in the contemporary breath, constitute an accusation against a nonhuman policy of surveillance and punishment. Twice a day, the space of the church is transformed into a factory, the act of dividing into two categories by capitalist and work and divorcing by accident is embodied as a social ethic. It is against the phenomenon that the structure of which no man exists is no longer institutionalized. The revolutionary movement aimed at breaking the framework of this hunt manifests itself in the two manifestos mentioned above, and Karl Marx completes the culmination of the utopia that must be achieved through the Declaration of the Communist Alliance by placing his being in the position of "eternal refugee". By choosing to die in his freedom developed during Jeon Bong-joon's trial, he also completes the people's spirit of revolution. In the case of simultaneous exploitation in East and West, the form of oppression is the withdrawal of capital from domination and power, and a new alternative to this is the philosophical context that allows the establishment of a new paradigm with "man is the greatest capital".

Currently, liver transplantation is the only available remedy for patients with end-stage liver disease. Conservation of transplanted liver graft is the most important issue as it directly related to patient survival. Carbonyl reductase 1 (CBR1) protects cells against oxidative stress and cell death by inactivating cellular membrane-derived lipid aldehydes. Ischemia-reperfusion (I/R) injury during living-donor liver transplantation is known to form reactive oxygen species. Thus, the objective of this study was to investigate whether CBR1 transcription might be increased during liver I/R injury and whether such increase might protect liver against I/R injury. Our results revealed that transcription factor Nrf2 could induce CBR1 transcription in liver of mice during I/R. Pre-treatment with sulforaphane, an activator of Nrf2, increased CBR1 expression, decreased liver enzymes such as aspartate aminotransferase and alanine transaminase, and reduced I/R-related pathological changes. Using oxygen-glucose deprivation and recovery model of human normal liver cell line, it was found that oxidative stress markers and lipid peroxidation products were significantly lowered in cells overexpressing CBR1. Conversely, CBR1 knockdown cells expressed elevated levels of oxidative stress proteins compared to the parental cell line. We also observed that Nrf2 and CBR1 were overexpressed during liver transplantation in clinical samples. These results suggest that CBR1 expression during liver I/R injury is regulated by transcription factor Nrf2. In addition, CBR1 can reduce free radicals and prevent lipid peroxidation. Taken together, CBR1 induction might be a therapeutic strategy for relieving liver I/R injury during liver transplantation.

The purpose of this study was to investigate farmers' field survey to improve animal welfare certification standards and to obtain basic data on the animal welfare level for certified farmers to develop evaluation methods of animal welfare level suitable for domestic farm environment. The subjects of the study were selected 10 animal welfare laying certified farmhouses. The farming certified farming facility survey collected breeding form, head, feed and drink space, breeding density, length and shape of perch. Animal welfare was assessed by the presence of sand bath, spawning, enrichment measures, free range, feathers pecking. The results of the study showed that most the certified animal welfare laying hens complied with the certification standards. All the farms were providing the nest box, but there were farms with more than 20% of the spawning rate. The perches were provided in sufficient length, but only three of ten farms were using rounded perches. Feather damage has been identified in most survey farms, which is likely to be due to feather damage caused by roosters producing both fertilized eggs. In this study, 10 farm households were surveyed. It was not possible to represent the whole certified farmhouse. Therefore, it should be analyzed thoroughly to evaluate the level of animal welfare.

This study started with curiosity about theatre without its three elements and would reveal its possibility through performance and experiment and promote the expansion of each element and the development of a new form at the same time. After the occurrence of COVID-19, theatre has come up against a big limitation of contact-free, untact communication due to its inherent characteristic of 'presence.' For the survival of theatre in the rapidly changing world, it is desperately necessary to check the existing performance method and to be concerned about its development for the future. Thus, this researcher started from a more fundamental exploration of theatre focused on an "experiment of theatre without its three elements" and would sort out the three elements (actors, audience, and a play) from a macroscopic perspective. Also, the researcher would investigate the impacts of these elements on the performance and the possibility of theatre even after removing the elements through performance and experiment. This study consists of one performance and two experiments and is based on the interviews and progress details conducted by the planner and experimenter and the survey with the experiment participants. The significance of this study is its reflection on the essence of the genre, theatre, and the roles of all elements constituting that, not from a narrow perspective that would simply define the concepts of the elements but through the expansion and change of them. Furthermore, hopefully, it will be connected to the discovery of a new theatrical format that has not been considered through its combination with another genre.
