Purpose: We explored Koreans' perception of the meaning of death with dignity that Korean people. Methods: A phenomenological research methodology was applied. A total of 13 participants were sampled based on their age and gender. Participants were interviewed in depth from September 2015 through February 2016. Colaizzi's phenomenological analysis method was used for data analysis. To establish the validity of the study, we evaluated its realistic value, applicability, consistency and neutrality of the qualitative evaluation criteria of Lincoln and Guba. Results: Koreans' perception of death with dignity was structured as 19 themes, nine theme clusters and four categories. The four categories were "comfortable death", "good death", "resolving problems before death", and "death with good reputation". The theme clusters were "death without pain", "death submitting to one's fate", "death that is not ugly", "leaving good memories to others", "dying in a way we want", "death after proper settling of things", "dealing with chronic resentment before death", "death after living a good life", and "death with recognition". Conclusion: For Koreans, death with dignity meant not burdening others, settling things right and leaving good memories to their families and friends. Such perceptions can be applied to hospice care for terminally ill patients.

Immobilization of contaminants in subsurface environment is one of the major processes that determine their fate. Especially, immobilization by oxidative-coupling reactions, which is irreversible in the bio-chemical reactions and results in a significant reduction of toxicity, can be successfully applied for the remediation of contaminated soil and groundwater more effectively than conventional degradation. As a catalyst of this oxidative-coupling reaction, manganese oxide has many advantages in practical aspects as compared to microorganisms or oxidoreductive enzymes extracted from microorganisms, fungi, or plants. This paper is to present recent research achievements on the treatment mechanisms of various organic contaminants by manganese oxide. Especially, treatment methods of non-reactive organic compounds to Mn oxide are the main focus; i.e., application of reaction mediator, PAHs treatment method, combination with an appropriate pretreatment such as reduction using $Fe^0$, which suggests the potential of a wide range of engineering application. Concerning the natural carbon cycle processes, immobilization and stabilization by oxidative coupling reaction can be effectively applied as a environmentally-friend remediation method especially for aromatic contaminants which possess a high resistance to degradation.

Origins for the transconductance dispersion and the gate leakage current in a GaAs metal semiconductor field effect transistor were found using capacitance deep-level transient spectroscopy (DLTS) measurements. In DLTS spectra, we observed two surface states with thermal activation energies of 0.65 $\times$ 0.07 eV and 0.88 $\times$ 0.04 eV and an electron trap EL2 with thermal activation energy of 0.84 $\times$ 0.01 eV. Transconductance was decreased in the frequency range of 5.5 Hz ~ 300 Hz. The transition frequency shifted to higher frequencies with the increase of temperature and the activation energy for the change of the transition frequency was determined to be 0.66 $\times$ 0.02 eV. From the measurements of the gate leakage current as a function of the device temperature, the forward and reverse currents are coincident with each other below gate voltages lower than 0.15 V, namely Ohmic behavior between gate and source/drain electrodes. The activation energy for the conductance of electrons on the surface of MESFET was 0.63 $\times$ 0.01 eV. Comparing activation energies obtained by different measurements, we found surface states H1 caused the transconductance dispersion and the fate leakage current.

The purpose of this paper is to suggest to tackle the problem of poor cooperation in space activities, by re-examining the nature of the competitive political environment, and by building up a normative overarching framework, One of the most acute problems that hampers regional cooperation is the U.S. influence as represented in the MTCR, a supplier's cartel, as was evidenced in the ill-fate of the 2001 launch contract between China and Korea the next year. Notably China, the third space power in the world, has not been allowed to join the MTCR despite her application in June 2004. A possible reconciliation between China and the MTCR over her application for a partnership would set a cornerstone in building up a cooperative environment in the Northeast Asia. Just as the Helsinki process was an overarching norm building framework, comprising human rights, security and environmental issues, it would be desirable that a future peace framework in Northeast Asia dealing with the pending issues of Korean peninsula should also comprise of such broad issues as one relating to cooperation in space activities in the region. South Korea could tap expertise from her neighbor China. When South Korea become an independent space power either with her own technology or otherwise, she would be in a better position to play a role as a balancer in coordinating between the two neighboring space giants. It is remarkable that the Japanese led APRSAT has contributed much in establishing Sentinel Asia as a part of the Disaster Management Scheme, in that each participant, whether it be a state agency, or a private entity like a university or a research institute, can tap the common data to contribute to the common good of safety.

The aim of this study was to evaluate the effects of gamma irradiation (${\gamma}$-irradiation) at doses of 15, 30 and 45 kGy on chemical composition, anti-nutritional factors, ruminal dry matter (DM) and crude protein (CP) degradibility, in vitro CP digestibility and to monitor the fate of true proteins of full-fat soybean (SB) in the rumen. Nylon bags of untreated or ${\gamma}$-irradiated SB were suspended in the rumens of three ruminally-fistulated bulls for up to 48 h and resulting data were fitted to a nonlinear degradation model to calculate degradation parameters of DM and CP. Proteins of untreated and treated SB bag residues were fractionated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Digestibility of rumen undegraded CP was estimated using the three-step in vitro procedure. The chemical composition of raw and irradiated soybeans was similar. Results showed that phytic acid in ${\gamma}$-irradiated SB at dose of 30 kGy was eliminated completely. The trypsin inhibitor activity of 15, 30 and 45 kGy ${\gamma}$-irradiated SB was decreased (p<0.01) by 18.4, 55.5 and 63.5%, respectively. From in sacco results, ${\gamma}$-irradiation decreased (p<0.05) the washout fractions of DM and CP at doses of 30 and 45 kGy, but increased (p<0.05) the potentially degradable fractions. Gamma irradiation at doses of 15, 30 and 45 kGy decreased (p<0.05) effective degradability of CP at a rumen outflow rate of 0.05 $h^{-1}$ by 4.4, 14.4 and 26.5%, respectively. On the contrary, digestibility of ruminally undegraded CP of irradiated SB at doses of 30 and 45 kGy was improved (p<0.05) by 12 and 28%, respectively. Electrophoretic analysis of untreated soybean proteins incubated in the rumen revealed that ${\beta}$-conglycinin subunits had disappeared at 2 h of incubation time, whereas the subunits of glycinin were more resistant to degradation until 16 h of incubation. From the SDS-PAGE patterns, acidic subunits of 15, 30 and 45 kGy ${\gamma}$-irradiated SB disappeared after 8, 8 and 16 h of incubation, respectively, while the basic subunits of glycinin were not degraded completely until 24, 48 and 48 h of incubation, respectively. It was concluded that ${\gamma}$-irradiated soybean proteins at doses higher than 15 kGy could be effectively protected from ruminal degradation.

This study was intended to provide women who are supposed to experience childbirth with effective nursing care exploring the childbirth experience. The purpose of this paper is to give an answer to the question of what the childbirth experience is, and phenomenological method has been used for that purpose. 17 primiparous mothers right after delivery in one university hospital of J city were served as subjects for this research. Data were collected June to October, 1993 through in depth interview with subjects using unstructured and open questions about the childbirth experience. Van Kaam's phenomenological analysis method was used for the analysis of the data. The results of the study are summarized as follows : The contents of the experience which primiparous mothers had undergone through childbirth were pain, fear, worry, relief, lightness, thankfulness, unsatisfactory, unreality, holiness for a new life, identifying the meaning of life, becoming a mother. 1. Experience before delivery Mothers experienced pain, fear, worry, unsatisfactory, relief, and thankfulness before delivery. Subjects' descriptions about the pain appeared to be various ; unbearable pain, bearable pain, anticipated pain. And their reactions were also various ours ; some endured pain, sought alternative method i.e., surgery, didn't want to reexperience it, or accepted it as women's fate. Subjects experienced fear for anticipated pain, suffering pain, and possible delayed delivery progress and were worried about delivery progress and baby wellbeing. Also, Subjects were unsatisfied with professionals' unfaithful attitude, their spouses' absence, and the ignorance of their pain. But subjects became relieved at the accustomed surroundings, good progress of delivery, support of family, care of professionals and support of other family. And they expressed their thanks to the professionals and family members for doing their best and also to their mothers who gave birth to them. 2. Experience after delivery Subjects experienced lightness, thankfulness, unsatisfactory, worry, unreality, holiness for a new life, identifying the meaning of life, becoming a mother after delivery. Mothers experienced lightness from the fact that it is over, and freshness right after delivery. They were thankful that they delivered vaginally and had an easy delivery. Subjects who delivered female baby were unsatisfied and some were worried about rearing the baby. By confessing, "I have no specific feeling, I am very confused, It is unrealistic, I feel strange", they expressed the unrealistic aspect of childbirth experience. Subjects felt holiness for a new life for novelty and birth of life. They identified the meaning of life from the fact that they felt worthy, fulfilled their duty, had their own baby, accomplished an important affair. After they experienced what it is to be a mother, they realized with it is being a mother and had a rearing expectation for the baby. The results of the study will provide basic data for caring the childbearing women.

It is well known that increased incidences of lung, skin, and bladder cancers are associated with occupational exposure to PAHs. Animal studies show that certain PAHs also can affect the hematopoietic and immune systems and can produce reproductive, neurologic, and developmental effects. As a consequence, several studies have been attempted to investigate the fate of PAHs in atmospheric environment during the past decades. However, there is still a lack of information in regard to the atmospheric concentration of PAHs during the "Bon Fire Night". In this study, twenty-three polycyclic aromatic hydrocarbons and twenty-eight aliphatics were identified and quantified in the $PM_{10}$ and vapour range in Birmingham ($27^{th}$ November 2001-$19^{th}$ January 2004). The measured concentrations of total particulate and vapour (P+V) PAHs were consistently higher at the BROS in both winter and summer. Arithmetic mean total (P+V) PAH concentrations were $51.04{\pm}47.62$ ng $m^{-3}$ and $22.30{\pm}19.18$ ng $m^{-3}$ at the Bristol Road Observatory Site (BROS) and Elms Road Observatory Site (EROS) respectively. In addition arithmetic mean total (P+V) B[a]P concentrations at the BROS were $0.47{\pm}0.39$ ng $m^{-3}$ which exceeded the EPAQS air quality standard of 0.25 ng $m^{-3}$. On the other hand, the arithmetic mean total (P+V) aliphatics were $81.80{\pm}69.58$ ng $m^{-3}$ and $48.00{\pm}35.38$ ng $m^{-3}$ at the BROS and EROS in that order. The lowest average of CPI and $C_{max}$ measured at the BROS supports the idea of traffic emissions being a principle source of SVOCs in an urban atmosphere. The annual trend of PAHs was investigated by using an independent t-test and oneway independent ANOVA analysis. Generally, there is no evidence of a significant decline of heavier MW PAHs from the two data sets, with only Ac, Fl, Ph, An, 2-MePh, 1+9-MePh, Fluo and B[b+j+k]F showing a statistically significant decline (p<0.05). A further attempt for statistical analysis had been conducted by dividing the data set into three groups (i.e. 2000, 2001-2002 and 2003-2004). For lighter MW compounds a significant level of decline was observed by using one-way independent ANOVA analysis. Since the annual mean of $O_3$ measured in Birmingham City Centre from 2001 to 2004 increased significantly (p<0.05), it may be possible to attribute the annul reduction of more volatile PAHs to the enhanced level of annual average $O_3$. By contrast, the heavier MW PAHs measured at the BROS did not show any significant annual reduction, implying the difficulties of 5- and 6-ring PAHs to be subject to photochemical decomposition. The deviation of SVOCs profile measured at the EROS was visually confirmed during the "Bonfire Night" festival closest to the $6^{th}$ November 2003. In this study, the atmospheric PAH concentrations were generally elevated on this day with concentrations of Fl, Ac, B[a]A, B[b+j+k]F, Ind and B[g,h,i]P being particularly high.

There are currently 214 orphanages in Korea which house approximately 13,873 orphans aged between 3 and 18; this accounts for about 0.12% of all children in the same age range. Some have lost their parents, but most have come after their parents divorced or broke up. This means majority of the children in Child Care Centers have parents. Traditional virtue of obedience to parents (Hyo) was regarded as one of the highest value in Korea. Also the interaction between parents and their children was regarded as basic human nature that parents look after, both physically and spiritually, their children until they become one of the matured social member. Raised without having a chance to realize their filial duty and not having been cared for by their parents, most orphans feel that they lack something in their lives when compared with friends. In the end, they live their lives longing for their parents and go through mental discord about their parents. This paper is focused on understanding orphans' experience and views on parents. I approached the issue by applying van Manen's Hermeneutic Phenomenological Approach. The interviews, along with other reference material were phenomenologically reflected to draw essential themes as follows; 1. Orphans of pre-school age hazily long for parents without having any practical image of their parents. 2. They occasionally dream meeting their parents with image that can only last in their dreams, and this continues up through middle school. 3. At the age of elementary school, they crave the image of parents as they see their friends with their parents. 4. They start to despise their parents for having abandoned them when they reach puberty. 5. Meanwhile, as their vague image of parents fade away, they attempt to give up their thoughts toward their parents. 6. Highteens start to think in terms of fate. 7. They don't long for their parents anymore as they used to, but still wishes to meet them at least once. However, they don't want to start any kind of a relationship with them. 8. They fear that they will also fail in raising families of their own, and making their children orphans too, just like their parents have. They simply don't want to follow their footsteps. 9. Thinking that they were abandoned by their parents, they are reluctant to believe other people.

Water flow simulations for environmental problems often require local detailed analyses for better understanding and accurate prediction of the fate of pollutant in water bodies. This study deals with the development and application of a two-dimensional flow an dispersion model to the coastal water area to find out possible changes due to the wide port development plan. As far as the spatial discretization is concerned, the finite element method is attractive because of its flexibility and ability to naturally treat complex coastal geometries. The model uses finite element theory and the Galerkin weighted-residual approach as its basis. Developed model is applied to the Busan New harbor Construction site. Results from the model were compared with the measured water level and flows in four stations. The flow pattern by the model shows to be similar to the observed data away from the construction site where the flow is not affected. From the simulation results, it is concluded that the model may be useful for numerous other studies for planning and management purposes, especially flow and pollution dispersion in the coastal water bodies where the flow is so complicated.

In order to increase the persistence of plant growth promoting rhizobacteria (PGPR) in rhizpsphere soil, the growth of tomato was examined after the application of Arthrobacter woluwensis ED immobilized in alginate bead, which was known as PGPR. When tomato seedlings were treated with A. woluwensis ED of $1{\times}10^6$ cells g $soil^{-1}$ and incubated for 30 days in a plant growth chamber, the shoot length, root length, fresh weight and dry weight of the grown tomato plants treated with the suspended inoculants significantly increased by 36.2, 59, 51.1, and 37.5%, respectively compared to those of the uninoculated control. The treatment of the immobilized bacteria increased those by 42, 67.4, 62.5, and 60.4%, respectively compared to those of the uninoculated control. Therefore, the enhancement of tomato growth by the treatment of the immobilized bacteria was higher than those by the suspended inoculants. The effects of the inoculation on indigenous bacterial community and the fate of the inoculated bacteria were monitored by denaturing gradient gel electrophoresis analysis. The DNA band intensity of A. woluwensis ED in the tomato rhizosphere treated with the suspended inoculants continuously decreased after the inoculation, but the band intensity in the tomato rhizosphere soils treated with the immobilized inoculants showed the maximum at 1 week after inoculation and the decreasing rate was less than that of the suspended inoculants, which indicated the longer maintenance of the immobilized bacteria at rhizosphere soils. Therefore, encapsulation of PGPR in alginate beads may be more effective than liquid inoculant for the plant growth promotion and survival of PGPR at plant rhizosphere.
