In this era of transnational migration, it is necessary to recognize the signs of the times regarding religion. During the globalization of Korean society, migration cannot be avoided, and as such, Korea should look towards hospitality with practical themes of religion and religious people aiming for peace. Therefore, this study examines the concept of 'conscience' in Daesoon Thought because this understanding of the conscience connects people to their heavenly endowed nature and their original selves. First, in order to explore the religious ideas of hospitality for transnational migration, this study viewed the issue through three analytical frames: exclusive perception, tolerant perception, and pluralistic perception, and then criticized these from the perspective of hospitality. Furthermore, hospitality was viewed as an attitude of attempting to expand one's sense of self in dealing with others. Religiously, it was derived that the expansion of one's sense of self should aim for relationships of Sangsaeng (相生 mutual beneficence) as these go beyond mere symbiosis. In addition, as a way to overcome otherness, the religious idea of unconditional hospitality towards migrants was explored focusing on the concept of conscience in Daesoon Thought. In Daesoon Thought, the mind is the source of Heaven and Earth and also the essence of human existence. There are two aspects of mind that arise in humans: conscience and private interest. In Daesoon Thought, the conscience enables human potential and aims for a return to the source. In other words, it is to abandon private-interest and regain one's nature and the essence of one's personality. This can be done through Mujagi (無自欺 Guarding against Self-deception); embodying and maintaining a mind that does not deceive itself. In Daesoon Thought, the practice of Sangsaeng ethics based on Mujagi is expressed as Haewon Sangsaeng (解冤相生 the Resolution of Grievances for Mutual Beneficence) and working for the betterment of others. Therefore, when the relational and communal perspectives of Daesoon Truth and Sangsaeng are reinforced, the argument for developing the practical ethics of Haewon Sangsaeng based on Mujagi into the transformation of the human spirit expressed as unconditional hospitality was found to be sound.

There are increasing numbers of North Korean defectors. Many of them enter universities and major in social welfare in order to get jobs. As a required course, they must participate in field practicum and many difficulties are expected. This study aims to examine the North Korean defectors' practicum experience in specific, and to support more effectively in the field work education. To achieve this purpose, female North Korean defectors who go to G cyber university and have finished their field practicums, were interviewed in an in-depth interview. The data were analyzed with the open coding through the constant comparison method as Grounded theory's initial analysis. As the result, the following was found: 49 concepts, 18 sub-categories, and 7 categories. The categories include difficulties in the process of preparation for and beginning with various obstacles; confusion due to the differences between the North Korean and South Korean culture; tasks and functions that were not expected, personal relationships which were burdensome to them; feeling a lack of professional competence; inevitable environmental circumstances, and personal problems. Based on the results, suggestions for better support in field practice education in the side of universities, community agencies, individual students and the general society were addressed.

Coastal plant species, Plantago camtschatica Cham. native to the coastal region of the East Sea were sampled and then morphologically different 20 endophytic fungal strains were purely isolated. Phylogenetic analysis of isolates was done by the Bayesian program based on sequenced internal transcribed spacer (ITS-rDNA) region. Culture filtrates of each of 20 isolates were treated to Waito-c rice (WR) seedlings for verifying plant growth-promoting activity, respectively. As the results, E/PC/10/1 strain showed the highest plant growth-promoting activity among them. The culture filtrate of the strain E/PC/10/1 was revealed as containing gibberellins ($GA_1$, $GA_3$, $GA_4$) by using HPLC, and gas GC/MS with selected ion monitoring (SIM). Finally, this strain was identified as novel Penicillium spinulosum species that producing new GAs with microscopic observation and further molecular analysis with beta-tubulin gene sequence.

This paper aims to define the leadership of Gunja (君子, translated into prince, gentleman, or ideal man) based on Confucian Classics which offer the general values and norms of individuals' virtue and social virtuous acts. Thus, humanitarianism is regarded as true value, and the values of a virtuous person who properly practices social human relationships are discussed. The real worth of Gunja image is discussed as a true human image of "self-completion and completion of all things" (成己成物) which involves the convergence of truth, good and beauty where there is a sense of harmony and balance, where there is stern self discipline and self cultivation and where win-win values of human relationships are created. Confucian saint (聖人), wise man (賢人), great man (大人), and gentleman (君子) mean social leaders. They practice human morals, enlighten and beautify society with teachings, and are indicated as equipped with mental and material harmony, good character and competence, and economic power and morality. People today pursue their own personal growth according to their material preferences rather than pure intellectual cultural values, and are engrossed in visually beautiful external unlimited competition. In this digital age, we are supposed to demonstrate our individuality, but many people are obsessed with appearance, go on severe diet, and lose their health beauty, and consequently suffer mental stress. This trend fuels obsession with appearance and the sick practice of valuing appearance. As an alternative method to overcome this phenomenon, we need a leader image with the convergence of truth, good and beauty, which is characterized by internal self cultivation, external professionalism, and handsome and solid character. Confucian thoughts consist in practicing the Way of disciplining oneself for governing others (修己治人). Self discipline involves developing personal virtuous ability for cultivating a virtuous character, and governing others involves interacting to work together in society and to have right human relationships. Thus, leaders should impress not only themselves but also others. Self discipline for governing others means cultivating virtue for oneself and leading others. A true leader has self introspection and establishes himself through self discipline so that he can govern others or reach the realm of settling others where people live together. As all things have a value and a virtue, humans endeavor to cultivate character and virtue by learning and studying for securing their professionalism, reliability, character and ability, so as to create their own brand value. Personal character does not come from a high position, wealth and power. Character is a personal virtue, and is cultivated as immaculate and fresh through self discipline. As such, it well matches with a clean and clear spirit. This offers the ideal leader as the Guja image who has an extremely humane character, as well as being equipped with inherent virtues of intellect, benevolence and courage. Self development can foster virtue and self management through self leadership and self discipline. The leader in the relationship area can practice his virtue through virtuous acts, in other words, even think from another person's perspective. Such leader is mentioned as the principle of measuring square in the Great Learning. In our viewpoint, the beauty of character can breed the seed of virtue through intellect, benevolence and courage, the beauty of win-win can realize the right virtue by showing exemplary acts to others through considerateness, and the beauty of harmony can love and care for others like me through the principle of measuring square, thereby realizing the universal principle of virtue and harmony, which is like my mind. As such, the ideal leader, when his virtue and mind of being considerate of others all blending well, can exercise his ability to the full, can live together and coexist with many people, and can grow again into a triumphant relationship.

Physicochemical and morphological characteristics of biopellets produced in "control" and modified UASB reactor were investigated to compare the reactor performance with regard to the hydrogen partial pressure. The characteristics of biopellet produced in modified UASB reactor operated with high hydrogen partial pressure were better than those of "control" reactor operated with relatively lower hydrogen partial pressure, therefore the hydrogen partial pressure effected greatly on the formation and stability of the biopellet. Furthermore, pellets from the UASB system with modified settler showed a better settleability and biomass holding capacity. The chemical composition of biopellet was distinctively different from that of common bacterial formula, $C_5H_7O_2N$. Biopellets was composed the large fraction of nitrogen in comparison with common anaerobic microbes. These results implicated the existence possibility of polypeptide-type extracellular polymer. The morphological characterization with SEM showed that microorganisms observed at surface of biopellet produced in modified UASB reactor operated with high $P_{H_2}$ condition were very similar in shape and size to the Methanobrevibactor arboriphilus-$H_2$ utilizing methanogen. The microorganisms was distinguished from those of "control" reactor operated with low $P_{H_2}$ condition. From these results, it could be explained the hydrogen partial pressure effects on pelletization mechanism.

In heavily industrialized areas, soil sites are contaminated with high concentrations of heavy metals. These pollutants are highly accumulated to the human body through the food web and cause serious diseases. To remove heavy metals from the soil, a potential strategy is the environmental friendly and cost effective phytoremediation. For the enhancement of remediation efficiency, the symbiotic interaction between the plant and plant growth-promoting rhizobacteria (PGPR) has been attended. In this review, the interaction of the plant and PGPR in the heavy metal-contaminated soil has been reviewed. The physicochemical and biological characteristics of the rhlzosphere can influence directly or indirectly on the biomass, activity and population structure of the rhizobacteria. The root exudates are offered to the soil microbes as useful carbon sources and growth factors, so the growth and metabolism of rhizobacteria can be promoted. PGPR have many roles to lower the level of growth-inhibiting stress ethylene within the plant, and also to provide iron and phosphorus from the soil to plant, and to produce phytohormone such as indole acetic acid. The plant with PGPR can grow better in the heavy metal contaminated soil. Therefore higher efficiency of the phytoremediation will be expected by the application of the PGPR.

The movie WALL-E shows the Earth which has been overrun with garbage and devoid of plant and animal life, and humans who try to restore the ecosystem. The aim of this study is to find the implications of children's education with a detailed analysis of the movie's theme. The analysis method is the interpretive analysis model that is one of the qualitative methods of data analysis based on the concept of Wolcott. First, the Earth is an abandoned planet covered in trash: the Axiom is a haven for morbidly obese and indolent people. The main area of the earth's destruction, and the captain's cabin is the place to find a clue to awakening and change. Second, with the lapse of time, the Axiom becomes a ship allowing their return to earth. The Earth, recognized as their homeland, turns in to the land of hope when people return. Third, the cleaning robot Wall-E, as a main agent of change, has changed humans as well as itself. The results showed that we found nature-friendly development, destruction of nature, the criticism of modern civilization, the sanctity of life, ecological consciousness, coexistence, symbiosis and a win-win principle in our research.

Ore mineralization of the Hwanghak copper deposit in the Ogsan area occurred in three stages of quartz (stage I and II) and calcite (stage III) veining along fissures in Early Cretaceous sedimentary rocks. Ore minerals are pyrite, pyrrhotite, chalcopyrite (dominant), sphalerite, hematite, galena, and Ag-, Pb-, and Bi-sulfosalts. These were deposited during the first stage at temperatures between $370^{\circ}C$ and < $200^{\circ}C$ from fluids with salinities between 0.5 and 7.6 equiv. wt. % NaCl. There is evidence of boiling and this suggests pressures of less than 180 bars during the first stage. Equilibrium thermodynamic interpretation accompanying with mineral paragenesis and fluid inclusion data indicates that copper precipitation in the hydrothermal system occurred due to cooling and changing in chemical conditions ($fs_2$, $fo_2$, pH). Gradual temperature decrease from $350^{\circ}$ to $250^{\circ}C$ of ore fluids by boiling and mixing with less-evolved meteoric waters mainly led to copper deposition through destabilization of copper chloride complexes. Sulfur isotope values of sulfide minerals decrease systematically with paragenetic time from calculated ${\delta}^{34}S_{H_2S}$ values of 8.2 to 4.7‰. These values, together with the observed change from sulfide-only to sulfide-hematite assemblages and fluid inclusion data, suggest progressively more oxidizing conditions, with a corresponding increase of the $sulfate/H_2S$ ratio of hydrothermal fluids. Measured and calculated hydrogen and oxygen isotope valutls of ore-forming fluids suggest meteoric water dominance, approaching unexchanged meteoric water values.

The Colony of Selaginella involvens (Sw.) Spring in Sanyang-myeon, Mungyeong-si, can be divided into five types, and in the past, it was said that Selaginella involvens (Sw.) Spring formed colonies throughout the colony and grew naturally, but now it remains only in some sections. It was found that the Selaginella involvens (Sw.) Spring colony was damaged by artificial and natural factors, and as an artificial factor, the Selaginella involvens (Sw.) Spring was proven to be effective for medicinal and cremation, and many people were damaging the Selaginella involvens (Sw.) Spring colony without permission. Naturally, vines thrive and Selaginella involvens (Sw.) Spring die, and the reality is that the entire colony of Selaginella involvens (Sw.) Spring is in danger of being damaged if maintenance is not performed. On the other hand, there are sections that reproduce with symbiosis with some herbaceous plants, so it is necessary to plan and implement conservation strategies. In order to preserve the Selaginella involvens (Sw.) Spring colony, CCTV is needed to prevent artificial damage, and on the contrary, install facilities such as fences can easily burn up and create worse scenery, so it can preserve the good environment, restore recoverable areas, and install supplementary buffer zones.

In adolescence, the symptoms of depression are more various and different from those of adult. Conduct behaviours are frequently represented in adolescent's depression. The patients who have the depression and conduct disorder are defined as depressive condor disorder in ICD-10. We hypothesized that there might be different parental rearing patterns between the patients with depression alone and the depressive conduct disorder. We applied children's depression inventory (CDI), parental rating form for conduct disorder based on DSM-III-R, and parental bonding instrument (PBI) to patients and normal control adolescent group. The results were as follows : 1) There were no significant differences in severity of depressive symptoms, maternal care, maternal overprotection, and paternal care. 2) Paternal overprotection showed significant higher scores in depressive conduct disorder group than depression group and normal control group. 3) There were positive correlations in the severity of depressive symptoms and behavior problems in all subjects. 4) There were no correlations in maternal care and overprotecion with conduct problems, but with depressive symptoms in all subject. 4) There were no correlations in paternal care with conduct problems and depressive symptoms in all subjects. 5) There were significant correlations in patienral overprotective, intrusive attitudes with conduct problems, not with depressive symptoms in all subjects.
