  • (Background) Recent biotechnological breakthroughs are shedding new lights on various ethical and legal issues about human biological material. Since Rudolph Virchow, a German pathologist, had founded the medical discipline of cellular pathology, issues centering around human biological materials began to draw attention. The issues involving human biological materials were revisited with more attention along with series concerns when the human genome map was finally completed. Recently, with researches on human genes and bioengineering reaping enormous commercial values in the form of material patent, such changes require a society to reassess the present and future status of human tissue within the legal system. This in turn gave rise to a heated debate over how to protect the rights of material donors: property rule vs. no property rule. (Debate and Cases) Property rule recognizes the donors' property rights on human biological materials. Thus, donors can claim real action if there were any bleach of informed consent or a donation contract. Donors can also claim damages to the responsible party when there is an infringement of property rights. Some even uphold the concept of material patents overtaking. From the viewpoint of no property rule, human biological materials are objects separated from donors. Thus, a recipient or a third party will be held liable if there were any infringement of donor's human rights. Human biological materials should not be commercially traded and a patent based on a human biological materials research does not belong to the donor of the tissues used during the course of research. In the US, two courts, Moore v. Regents of the University of California, and Greenberg v. Miami Children's Hospital Research Institute, Inc., have already decided that research participants retain no ownership of the biological specimens they contribute to medical research. Significantly, both Moore and Greenberg cases found that the researcher had parted with all ownership rights in the tissue samples when they donated them to the institutions, even though there was no provision in the informed consent forms stating either that the participants donated their tissue or waived their rights to ownership of the tissue. These rulings were led to huge controversy over property rights on human tissues. This research supports no property rule on the ground that it can protect the human dignity and prevent humans from objectification and commercialization. Human biological materials are already parted from human bodies and should be treated differently from the engineering and researches of those materials. Donors do not retain any ownership. (Suggestions) No property rule requires a legal breakthrough in the US in terms of donors' rights protection due to the absence of punitive damages provisions. The Donor rights issue on human biological material can be addressed through prospective legislation or tax policies, price control over patent products, and wider coverage of medical insurance. (Conclusions) Amid growing awareness over commercial values of human biological materials, no property rule should be adopted in order to protect human dignity but not without revamping legal provisions. The donors' rights issue in material patents requires prospective legislation based on current uncertainties. Also should be sought are solutions in the social context and all these discussions should be based on sound medical ethics of both medical staffs and researchers.

  • Two-lane roads that occupy more than a half of rural highways in Korea have operational problems such as traffic congestion problems due to relatively high traffic volume and safety problems due to overtaking risks in two-lane highways. To solve these problems, a 2+1 road pattern that enables to improve traffic safety and operational efficiency of two-lane highways has been applied in Europe. In this study, in-depth applicability of 2+1 roads to Korean rural highways was investigated based on review results of the successful experience of European 2+1 roads. Then, given the Korean two-lane highway conditions, the service traffic volumes for Korean 2+1 roads was estimated. The analysis results showed that 17,000 veh./day might be the maximum traffic volumes for Korean 2+1 roads.

  • The growth and development of Gwangyang city was a result of the POSCO Gwangyang Works, and Gwangyang city is one of typical firm citys in Korea. The objective of this study is to identify and examine the change of migration and population structure in Gwangyang city from 2001 to 2010. Since 1981, total number of population of Gwangyang city increased from 78,478 in 1981 to 145,512 in 2010. The population structure by age was changed with population increase since 2001, and 30-40 aging group was 35% of total in 2010. During 2001-2010, the netmigraion showed -2,925 people, however, the number of inmigrants were overtaking the number of out-migrants since 2008. The most common reason of in-migrants was occupation(49.5%). Factors influencing Gwangyang City's population growth and oversupply are the location of POSCO Gwangyang Works and steel-related enterprises, opening and construction of Gwangyang container berth, the related development projects and establishment of Gwangyang Bay Area Free Economic Zone, and the local policies of Gwangyang City connected with these large-scale national projects. As a result, the number of manufacturing-related businesses increased due to various regional development projects conducted in Gwangyang City, and the growth of the business continued to increase due to the increase of younger people and births.

  • The current traffic regulations in Korea stipulate that traffic should keep to the right according to the Road Traffic Act; thus, customarily, the 'seat-on-the-left' system has been maintained. However, an increased number of 'seat-on-the-right' vehicles are being imported via a variety of routes from foreign countries, especially from Japan. According to the data from July 2004, 1,343 cargo vehicles and 593 passenger vehicles (for diplomats, etc.) were currently being driven on domestic road. As these 'seat-on-the-right' vehicles are not compatible with the domestic transportation system of driving on the right side of the road, there is a high risk of accidents. Experiments show that such system-driver mismatch causes longer operation time for directional signals, higher error frequency in yielding due to additional mental adjustments for 'seat-on-the-right' vehicle drivers. These are, therefore, influential factors which can lead to possible accidents. Furthermore, when the experiments test the visual range during overtaking maneuvers, the visual range of the drivers in the 'seat-on-the-left' vehicle was 2.95 meters as opposed to 1.7 meters for the drivers in the 'seat-on-the-right' vehicle. (In the experiment, the drivers were instructed to look at the paper cup 10 meters away from the back of drivers' seat.) The results demonstrate that it is necessary to have additional safety measures be implemented for the 'seat-on-the-right' vehicles.

  • When using a distributed system, it is very important to know the intention of a target ship in order to prevent collisions. The action taken by a certain ship for collision avoidance and the action of the target ship it intends to avoid influence each other. However, it is difficult to establish a collision avoidance plan in consideration of multiple-ship situations for this reason. To solve this problem, a Distributed Stochastic Search Algorithm (DSSA) has been proposed. A DSSA searches for a course that can most reduce cost through repeated information exchange with target ships, and then indicates whether the current course should be maintained or a new course should be chosen according to probability and constraints. However, it has not been proven how the parameters used in DSSA affect collision avoidance actions. Therefore, in this paper, I have investigated the effect of the parameters and weight factors of DSSA. Experiments were conducted by combining parameters (time window, safe domain, detection range) and weight factors for encounters of two ships in head-on, crossing, and overtaking situations. A total of 24,000 experiments were conducted: 8,000 iterations for each situation. As a result, no collision occurred in any experiment conducted using DSSA. Costs have been shown to increase if a ship gives a large weight to its destination, i.e., takes selfish behavior. The more lasting the expected position of the target ship, the smaller the sailing distance and the number of message exchanges. The larger the detection range, the safer the interaction.

  • Aggregate is used to produce stable materials like concrete and asphalt and is fundamental to meet the social needs of housing, industry, road, energy and health. A total of 42.35 billion tons of aggregate were produced in 2021 worldwide, an increase of 0.91% compared to the previous year. Among them, 2 billion tons were produced in China, India, European Union and United States, making up to 71.75% of the share. South Korea has witnessed a constant increase in aggregate production, overtaking Mexico and Japan for seventh place with 390 million tons and 0.85% of the share. The industrial sand and gravel produced globally amounted to 352.66 million tons. The top seven countries with the highest production were China, United States, Netherlands, Italy, India, Turkey and France, and their production exceeded 10 million tons and held a share of 74.69%. Exports of natural rock recorded $21.68 billion in 2021, increased by $2.3 billion compared to the previous year, while exports of artificial rock increased by $2.66 billion to $13.59 billion. Exports of sand reached $1.71 billion with United States, Netherlands, Germany and Belgium being the four countries with the highest exports of sand. The four countries exported more than $100 million in sand and took up 57.70% of the total amount. Exports of gravel totaled $2.75 billion, with China, Norway, Germany, Belgium, France and Austria in the lead, making up to 48.30% of the total share. The aggregate quarry started to surge in the 1950s due to the change in people's lifestyle such as population growth, urbanization and infrastructure delvelopment. Demand for aggregate is also skyrocketing to prevent land reclamation and flood caused by sea-level rise. Demand for aggregate, which was around 24 gigatons in 2011, is expected to double to 55 gigatons in 2060. However, it is likely that aggregate extraction will heavily damage the ecosystem and the world will eventually face a shortage of aggregate followed by tense social conflict.

The Concept of 'the Former World and the Later World' in Daesoon Thought as Introduced via the Diagrams of The Comprehensive Mirror of Taegeukdo (『태극도통감』의 도상을 통해 본 대순사상의 '선·후천' 개념)

  • In The Canonical Scripture (典經), the core scripture of Daesoon Thought, the Former World and the Later World are divided into the Era of Mutual Contention and the Era of Mutual Beneficence. This concept of the Former World and the Later World appears in diagrams on I-Ching Studies (易學) in the text titled, The Comprehensive Mirror of Taegeukdo (太極道通鑑). In I-Ching Studies, Anterior Heaven (先天) and Posterior Heaven (後天) are the main concepts in Song Dynasty diagram books on I-Ching Studies. Among the diagrams of I-Ching Studies, Fuxi's Diagram of the Sequence of the Eight Trigrams, Fuxi's Diagram of the Positions of the Eight Trigrams, Fuxi's Diagram of the Sequence of the 64 Hexagrams, and Fuxi's Diagram of the Positions of the 64 Hexagrams correspond to the Anterior Heaven, and King Wen's Diagram of the Sequence of the Eight Trigrams and King Wen's Diagram of the Positions of the Eight Trigrams correspond to Posterior Heaven. In The Comprehensive Mirror of Taegeukdo, the diagrams of I-Ching Studies are reinterpreted according to Daesoon Thought. The Diagram of the Eight Trigrams of King Wen's Era corresponds to King Wen's Diagram of the Eight Trigrams in I-Ching Studies. This diagram was drawn according to the text in Chapter Five of the Treatise of Remarks on the Trigrams. This diagram corresponds to "the Era of the Nobility of Earth (地尊時代)" centered on the trigram kun (坤 / ☷ ground). Fuxi's Diagram of the Positions of the Eight Trigrams in I-Ching Studies corresponds to The Diagram of the Positions of the Eight Trigrams of Fuxi's Era in Daesoon Thought. The most significant feature of this diagram is that the trigrams assigned to the directions of north and south match the hexagram indicating the obstruction of Heaven and Earth. This is hexagram 12 (否), meaning "obstruction," and it depicts no exchange or communication between Yin and Yang. Naturally, this symbolizes mutual destruction overtaking Yin and Yang. Daesoon Thought expresses this as "the Era of the Nobility of Heaven (天尊時代)." The most significant feature of The Diagram of the Eight Trigrams of the Corrected Book of Changes in The Comprehensive Mirror of Taegeukdo is that the trigrams assigned to the directions of south and north are indicative of hexagram 11, Peace on Earth and in Heaven (泰). This is a diagram in which mutual destruction is resolved through the Five Phases because the trigrams for water (坎 / ☵) and fire (離 / ☲) are in a corrected orientation. Therefore, this diagram symbolizes a world "free from Mutual Contention" and "the Era of Human Nobility (人尊時代)." According to the contents of The Canonical Scripture, the Supreme God performed the Reordering Works of the Three Realms to correct the Mutual Contention of the Former World, and as a result, the Mutual Contention of the Former World will give way to the implementation of the Dao of Mutual Beneficence. The Supreme God's Reordering Works of the Three Realms have been completed in the realm of divine beings, but in the Later World, they appear as an Earthly Paradise where the Dao of Mutual Beneficence is realized. The diagram depicting the Later World is The Diagram of the Eight Trigrams of the Era of the Corrected Book of Changes in The Comprehensive Mirror of Taegeukdo.
