  • The viability loss or death of weed seeds buried in soil can be induced by infrared irradiation which has good penetration in moist soil. By using this principle of pre-emergence soil-treatment, the study was carried out to obtain basic information needed to develop the effective weed control method for the production of less polluted agricultural products. An apparatus for irradiating infrared was constructed by using ceramic material with high emissivity. The LPG was used as fuel for producing infrared by heating ceramic material. The soil heated in this study was loam with four levels of moisture contents (0.6, 5.7, 10.7, 15.1 % wb). The temperature distribution was measured at various soil depths when soil with different moisture content was irradiated with infrared for three different times (30, 60, 90 sec). The soil depths with duration time of minimum 3 minutes over $80^{\circ}C$, temperature inducing viability loss of weed seeds, were investigated. When the moisture content of soil was 0.6 and 5.7 % wb, the soil depths which can induce viability loss of weed seeds was greatly increased with increasing irradiation time. However, any depths of soil tested in this study was not reached to the temperature of $80^{\circ}C$ when 30 seconds of irradiation time was applied on soil with moisture content of 10.7 or 15.1 % wb. Generally, the soil depth needed for viability loss of weed seeds was decreased with increasing moisture content of soil. Also, longer irradiation time was required to induce viability loss of weed seeds with increasing moisture content of soil.

  • The 2001 Leonid meteor storm has been observed all over the world, and its most intense flux since the last few decades has caused great interest among both laymen and experts. Especially, its maximum hours occurred at dawn hours of Nov. 19 in the east Asia, during which moonless clear night at the Mt. Bohyun allowed us near perfect condition of observation. Observation was carried out in the period of 01:00∼05:40(KST), which include the predicted maximum hours, with all-sky camera installed for upper atmospheric airglow research. Tn this paper we analyze 68 all-sky images obtained in this period, which contain records of 172 meteors. Utilizing the zenith hourly rate(ZHR) of 3000 and magnitude distribution index of 2, which were reported to International Meteor Organization by visible observers in the east Asia, we estimate the limiting magnitude of about 3 for meteors detected in our all-sky images. We then derive magnitudes of 83 meteors with clear pixel brightness outlines among the initially detected 172 meteors by comparing with neighbor standard stars. Angular velocities of meteors needed for computing their passing times over an all-sky image are expressed with a simple formula of an angle between a meteor head and the Leonid radiant point. The derived magnitudes of 83 meteors are in the range of -6∼-1 magnitude, and its distribution shows a maximum new -3mag. The derived magnitudes are much smaller than the limiting magnitude inferred from the comparison with the result of naked-eye observations. The difference may be due to the characteristic difference between nearly instantaneuous naked-eye observations and CCD observations with a long exposure. We redetermine magnitudes of the meteors by adjusting a meteor lasting time to be consistent with the naked-eye observations. The relative distribution of the redetermined magnitudes, which has a maximum at 0 mag., resembles that of the magnitudes determined with the in-principle method. The relative distribution is quite different from ones that decrease monotonically with decreasing magnitudes for meteors(1∼6) sensitive to naked-eye observations. We conclude from the magnitude distribution of our all-sky observation that meteors brighter than about 0 mag., appeared more frequently during the 2001 Leonid maximum hours. The frequent appearance of bright meteors has significantly important implication for meteor research. We noted, however, considerably large uncertainties in magnitudes determined only by comparing standard stars due to the unknown lasting time of meteors and the non-linear sensitivity of all-sky camera.

  • This study centering on 10 village - Bangjuks analyzed multifunctionality value of village Bangjuks which have been main water treatment system in Korean traditional villages. On the basis of understanding the structure and character of components such as the well, common spring, village waterway and others which making water-flow and consisting of aquatic system in Korean traditional village Bangjuk, the conclusion as the instrumental device of social and ecological role and ecological watershed management, securing the ecosystem soundness of the damaged or deteriated aquatic ecosystem due to the industrialization and urbanization is as below; 1. The traditional village Bangjuk was environmentally friendly hydraulic system which gathers waterways of village into a point including sewage water, retains and flows out to village through agricultural waterway. Through this Bangjuk, they have managed sewage and rainfall runoff flowed out village efficiently. It is not only a detention system of water but a kind of eco-friendly system that flow out water into the rivers after reusing and filtering it. 2. Around five traditional villages and five villages after modernization, this study classified the types of village Bangjuk as three types considering geographic location, size, etc; marsh type of low swamp, high water -low rice field type of natural flow stucture, low water - high rice field type requiring artificial irrigation facility. All the five traditional villages were turned out to be marsh type of low swamp. Geoji, Sanjeri, Ma-am, Yangchon of the agricultural villages were high water-low rice filed type, and Sangchoenri village was classified low water-high rice field type. 3. This study checked up the function of water purification of village Bangjuk. In Wonteo and Geji villages affected by discharge of village sewer and domestic sewage, the efficiency of ammonia nitrogen($NH_3-N$) and total phosphorus(T-P) was 56~95%, which was high. In Sangcheonri and Sanjeri villages strongly affected by stall and farmland, the efficiency of suspended solids(SS) was 70~85%, and that of total nitrogen(T-N) and total phosphorus(T-P) was 5.3~65%. 4. A water purification system can be found out in the system of village Bangjuk that filter out village sewage and rainfall runoff flowed through the settle and filter of pollution source and denitrification of plants. Through this system of village Bangjuk, it must be used as the basic facilities for the ecological watershed management. The sewage management system of village Bangjuk as a eco-filter must be used and studied as an eco-friendly facility for the ecological watershed management around the subwatershed and catchment.

  • This paper critically examines the role and function of religion prior to the full-out advent of the 4th industrial revolution. We can understand 'The vision of Daesoon Jinrihoe (大巡眞理會)' as a mission to foresee and create a prospective figure for a future society in the person of the Lord on High, Jeungsan (甑山) as a religious dimension. However, the existence ground of religion relies on giving positive meaning to the present time after reinterpreting religious doctrine to reflect changing realities. Jeungsan (甑山) said that the age to come is 'the age of the human majesty (人尊)'. This means that humans will take the lead and control the revolution of scientific technology to progress and benefit humanity. Problems such as 'human alienatio', 'increased polarization', and 'destruction of the environment' still arise and deepen because the motive of 'the Industrial Revolution' was built upon 'knowledge' within the context of a Knowledge-Based Society. Therefore, we can say that the role of religion will newly rise to the forefront in the era of the 4th industrial revolution. Consequently, religion should face matters squarely and suggest viable alternatives. This paper deals with reinterpreting the concept of 'the resolution of grievances for mutual beneficence (解冤相生)', one of the four teachings of Daesoon Jinrihoe, within the context of the coming era of the 4th industrial revolution. My research is divided into the following three parts: First, I determined the teachings of Daesoon Jinrihoe and the original meaning of 'the resolution of grievances for mutual beneficence', and then I disclosed the way we can reinterpret the general meaning of this concept for application in the ear of the 4th industrial revolution. Second, from the perspective of the religious dimension, I inquired into factors regarding alienation and conflict in the era of the 4th industrial revolution. I focused on human alienation from labor, identity confusion, potential conflicts between humans and post-humans, and the characteristics of the 4th industrial revolution. Third, I examined potential cures for alienation and conflict through the principle of the resolution of grievances for mutual beneficence. I tried to enlarge the interpretive prospects of Daesoon's main teaching in light of the era of the 4th industrial revolution through a new interpretation and application that employs the concept of 'the resolution of grievances for mutual beneficence (解冤相生)' in order to cure the alienation and conflict.

  • Since the birth of melodrama in the early Enlightenment era, it has flowed through various cultures and media. In order to grasp the principle of differentiation of melodrama and the direction of its change, a developmental approach to the formation process of melodrama is necessary. In this regard, this paper examines the formation process of modern melodrama and its aesthetic features around the time of the French Revolution. The modern melodrama was formed in the period between the end of the 18th century and the start of the 19th century. It was born at the intersectional point of the contradictions of the modern imagination and the political paradox of the French Revolution, which demanded an autonomous citizenship but did not recognize a woman as a citizen. The aesthetic of women's sacrifice and tears reproduced in the modern melodrama is a political aspiration to restore a corrupt society by glamorizing a woman as a moral icon. This was an icon to save a society under divide and crisis and a coordination of emotions to conceal sexist violence in the politics of the exclusion of women. The aesthetic of women's sacrifice and tears reproduced in modern melodrama has consistently been considered under negative evaluation such as a play of moral hypocrisy and vulgar drama. However, the academic interest in melodrama in the 1970s has been amplified due to the "Sirk-melo" which is a transition to the new aesthetic of women's sacrifice and tears, encompassing not only women, but also races and classes. In modern society, entering the era of uncertainty, where various social problems, national disasters, and global disasters have become commonplace, 'the aesthetic of women's sacrifice and tears' are shifting from gender differences to various victim narratives. Reviewing new theoretical trends and changes of recent melodrama as well as analyzing specific works are left as follow-up tasks.Since the birth of the melodrama in the early Enlightenment era, it has flowed through various cultures and media. In order to grasp the principle of differentiation of melodrama and the direction of its change, a developmental approach to the formation process of melodrama is basically necessary. In this regard, this paper examines the formation process of modern melodrama and its aesthetic features around the time of the French Revolution.

  • The purpose of this paper is to clarify the characteristics of 'Podeok' in Daesoon Jinrihoe. The term Podeok can cause some misunderstanding as the same word Deok (德 virtue) has long been used in the Eastern Tradition. In other words, for most people who are used to traditional thought, Podeok may be conflated with the similar word 'Deok (virtue)' as used within Confucianism. People who are familiar with Confucian culture might thereby misunderstand the term Podeok as an aspect of Confucian moral ethics, or they could misconstrue Daesoon Jinrihoe as having appropriated and misused Confucian ideas. Furthermore, there are other problems that could arise if people compare Daesoon Jinrihoe's 'Podeok' with 'Deok (virtue)' as used by Laozi. While Deok in Laozi's usage represents the ability of an individual who can exercise his or her rationality with excellence, Deok in Daesoon Jinrihoe indicates the idea of actualizing Mutual Beneficence and the conditions that enable Mutual Beneficence. If one understands Deok as used by Laozi to contain the meaning of Mutual Beneficence, then it is possible to think that the two tradition share a similar meaning of Deok as Podeok in Daesoon Jinrihoe pursues Mutual Beneficence as its ultimate value. In order to preemptively correct these misunderstandings, I need to clarify how the idea of Deok was born out of traditional thought and what meanings it embodies. Additionally, it is necessary to examine how it became meaningful in Confucianism, and how it was criticized and ascribed new meanings in Laozi's thought. Through these clarification, it will become clear that Deok originally indicated a religious ritual that the king of the Zhou Dynasty performed after receiving the heavenly mandate and assuming rule over the nation. Later, this idea was transformed into a moral virtue and norm by Confucius. This moral virtue and norm was criticized by Laozi as an unnatural form of control as it was understood by Laozi as a teleological argument justifying whether or not lives were to be saved or sustained based on the perceived merits of each individual. On the contrary, Deok in Daesoon Jinrihoe and traditional thought stand on a totally different theological bases. Deok in Daesoon Jinrihoe is a means to practice and realize the truth of the earthly paradise of the Later World and the truth of Mutual Beneficence which were posited to the world through Kang Jeungsan's Works of Haewon (grievance resolution) that resolved the pattern of mutual conflict that characterized the Former World. Therefore, the idea of Podeok in Daesoon Jinrihoe gains completion only on the premises of Haewon Sangsaeng (resolution of grievances for mutual beneficence) and Boeun Sangsaeng (reciprocation of favors for mutual beneficence), and the way to practice Podeok is to practice Haewon Sangsaeng and Boeun Sangsaeng. In addition, the subordinate virtues such as loyalty, filial piety, and faithfulness that exist within Daesoon Jinrihoe's religious practice are not same as those of traditional thought. They are new concepts of virtues drawn from the cosmological laws of Daesoon Jinrihoe. To be specific, the virtues of Daesoon Jinrihoe are not rules that create discrimination and mutual conflict, but are instead ethical rules established upon the basis of Heaven and Earth having been newly organized, and thus, they will bring virtuous concordance, harmonious union, and mutual beneficence. The idea of 'Podeok' in Daesoon Jinrihoe can be understood as a religious practice that requires doctrinal understanding and tangible practice in daily life of followers. In other words, it is not the same Deok of earlier traditional thought in East Asia, but is instead a religious truth by which practitioners realize the truth of Sangje's Works of Haewon in human world as they practice Haewon Sangsaeng and Boeun Sangsaeng.

Legal Issues on the Collection and Utilization of Infectious Disease Data in the Infectious Disease Crisis (감염병 위기 상황에서 감염병 데이터의 수집 및 활용에 관한 법적 쟁점 -미국 감염병 데이터 수집 및 활용 절차를 참조 사례로 하여-)

  • As social disasters occur under the Disaster Management Act, which can damage the people's "life, body, and property" due to the rapid spread and spread of unexpected COVID-19 infectious diseases in 2020, information collected through inspection and reporting of infectious disease pathogens (Article 11), epidemiological investigation (Article 18), epidemiological investigation for vaccination (Article 29), artificial technology, and prevention policy Decision), (3) It was used as an important basis for decision-making in the context of an infectious disease crisis, such as promoting vaccination and understanding the current status of damage. In addition, medical policy decisions using infectious disease data contribute to quarantine policy decisions, information provision, drug development, and research technology development, and interest in the legal scope and limitations of using infectious disease data has increased worldwide. The use of infectious disease data can be classified for the purpose of spreading and blocking infectious diseases, prevention, management, and treatment of infectious diseases, and the use of information will be more widely made in the context of an infectious disease crisis. In particular, as the serious stage of the Disaster Management Act continues, the processing of personal identification information and sensitive information becomes an important issue. Information on "medical records, vaccination drugs, vaccination, underlying diseases, health rankings, long-term care recognition grades, pregnancy, etc." needs to be interpreted. In the case of "prevention, management, and treatment of infectious diseases", it is difficult to clearly define the concept of medical practicesThe types of actions are judged based on "legislative purposes, academic principles, expertise, and social norms," but the balance of legal interests should be based on the need for data use in quarantine policies and urgent judgment in public health crises. Specifically, the speed and degree of transmission of infectious diseases in a crisis, whether the purpose can be achieved without processing sensitive information, whether it unfairly violates the interests of third parties or information subjects, and the effectiveness of introducing quarantine policies through processing sensitive information can be used as major evaluation factors. On the other hand, the collection, provision, and use of infectious disease data for research purposes will be used through pseudonym processing under the Personal Information Protection Act, consent under the Bioethics Act and deliberation by the Institutional Bioethics Committee, and data provision deliberation committee. Therefore, the use of research purposes is recognized as long as procedural validity is secured as it is reviewed by the pseudonym processing and data review committee, the consent of the information subject, and the institutional bioethics review committee. However, the burden on research managers should be reduced by clarifying the pseudonymization or anonymization procedures, the introduction or consent procedures of the comprehensive consent system and the opt-out system should be clearly prepared, and the procedure for re-identifying or securing security that may arise from technological development should be clearly defined.

  • Recently, the Korean Supreme Court released two important decisions concerning damages for the pain and suffering from Aircraft noise. The local people who are living near the Air Force practice site at Maehyang-ri and the Kimpo International Airport brought lawsuits against the Korean government requesting damages for their financial loss from the severe noise and the damages for their pain and suffering. Plaintiffs alleged that they suffered physical malfunctions, extreme disturbances and the reduction of property values from the extreme noises which were daily repeated. District Court of Seoul Province did not allow plaintiffs all but the damages for pain and suffering. Plaintiffs could not prove the causation between their financial loss and the noise. The Supreme Court confirmed the lower court's decision. Article V of the National Compensation Act (analogous to the Federal Tort Claims Act of the USA) reads, "the government shall be liable for any loss caused by the defect on establishment or maintenance of public facilities." In the two cases, the major issue was whether the government's establishment or maintenance of Air Force practice site and the airport was defective because they caused serious noise to surrounding neighbors. Previously, the Supreme Court interpreted the clause "defect on establishment or maintenance of public facilities" as failure of duty to provide safety measures to the degree generally required to ordinary manager. However the Court at this time interpreted differently that the defect could be found if the facility caused to any person loss to the degree intolerable. In the two cases the Court confirmed the lower court's finding that noise level at the site was severe enough to be intolerable. This standard is based on the severity of the loss rather than the failure of duty. It became easier for plaintiffs to prove the cause of action under this interpretation. The consequence of the ruling of these two cases is 'rush to the courtroom' by the local people at similar situations. The ruling of these two cases was not appropriate both in theory and in consequence. The Korean tort system is basically based on the theory of negligence. Strict liability is exceptional only when there is special legislation. The Court created strict liability rule by interpreting the Art. V of the National Compensation Act. This is against the proper role of the court. The result of the cases is also dismal. The government was already sued by a number of local people for damages. Especially the Department of Defense which is operating many airports nationwide has financial hardship, which will cause downsizing military practice by the Air Force in the long run, This is no good to anyone. Tens of millions of dollars which might be used for compensation might be better used to prevent further noise problem surrounding airports.

  • This study was conducted to develope a new type of ready-to-eat smoked Sebastes schlegeli product with high acceptability and extended shelf-life. A Sebastes schlegeli was salted at 4% salt concentration for 6 hr at $4^{\circ}C$. The cold smoking conditions for the salted Sebastes schlegeli consisted of drying for 2 hr at $22{\sim}24^{\circ}C$ followed by smoking for 2 hr at $22{\sim}24^{\circ}C$. The warm smoking conditions for the salted Sebastes schlegeli consisted of drying for 2 hr at $22{\sim}24^{\circ}C$, smoking for 2 hr at $22{\sim}24^{\circ}C$, and smoking again for 30 min at $47{\sim}50^{\circ}C$. The rancidity of the smoked Sebastes schlegeli did not change after 1 year storage at $-20^{\circ}C$ by monitoring the iodine value, peroxide value, and acid value. The number of viable cells in the cold and warm smoked samples were counted as $7.4{\times}10^5$ and $6.2{times}10^5$ CFU/g, respectively. Viable cells were not detected after 1 year of storage at $-20^{\circ}C$. The sensory evaluations of the processed Sebastes schlegeli showed that elastic texture increased with smoking as compared to with salting. There were no significant differences between cold and warm smoking in terms of sweetness, elastic texture, color, and smoke flavor. However, for overall acceptability, preference were in the oder of cold smoked, warm smoked, and salted.
