This study was focused on the contrasting pattern of part-time employment between Japan and Taiwan where the environments are similar in terms of expanding service industries and increasing flexibility of labor. In Japan, the expansion of part-time employment and its feminization have occurred, whereas they have not at all in Taiwan. The purpose of this study was to examine the reasons behind this phenomena, and to explore what relations they might have with the supply of women\`s labor in each country. Data analysis showed the following results. First, when the phenomena of part-time employment in Japan and Taiwan are summarized as \`active\` and \`inactive\` models, the difference could be explained by a structure-oriented approach rather than an individual-oriented approach. In other words, the difference between the two countries is mainly because of the structural characteristics of the labor market. a combination of capitalism and patriarchy, and an effect of state welfare and family policies rather than a \`voluntaristic choice\` due tn household work and child rearing. In light of this. the labor market segmentation and flexibility of labor theory in particular provided a useful frame for explanation. Second, with regard to the supply of women\`s labor, the difference between Japan and Taiwan could be found in the structure of the labor market and in family response strategies. The large corporation-oriented and strictly divided labor market structure in Japan activated part-time employment and its feminization, whereas, the small family-oriented businesses and less divided labor market in Taiwan supported the continuity of full-time employment of married women. There was also a room for informal employment in Taiwan which made part-time employment unnecessary. This study showed that even within similar environments of expanding service industry and pursuing flexibility of labor different measures and adaptations were possible. The case of Taiwan in particular, showed the significance of an informal labor market which was a part of industrialization process and a strategy of producing various products through a subcontracting network.

Deep geological cross-sectional data is generally not common nor easy to construct, because it is expensive and requires a great deal of time. As a result, geological interpretations at depth are limited. Many scientists attempt to construct geological cross-sections at depth using geological surface data and geophysical data. In this paper, we suggest a method for constructing cross-sections from limited geological surface data in a target area. The reason for this study is to construct and interpret geological cros-sections at depth to evaluate heat flow anomaly along the Yangsan fault. The Yangsan Fault passes through the south-eastern part of the Korean Peninsula. The cross-section is constructed from Sangbukmyeon to Unchonmyeon passing perpendicularly through the Yangsan Fault System trending NW-SE direction. The geological cross-section is constructed using the following data: (1) Lithologic distributions and main structural elements. (2) Extensity of sedimentary rock and igneous rock, from field mapping. (3) Fault dimension calculated based on geometry of exposed surface rupture, and (4) Seismic and core logging data. The Yangsan Fault System is composed of the Jain fault, Milyang fault, Moryang fault, Yangsan fault, Dongnae fault, and Ingwang fault which strike NNE-SSW. According to field observation, the western section of the Yangsan fault bounded by igneous rocks and in the eastern section sedimentary rocks are dominant. Using surface fault length we infer that the Yangsan Fault System has developed to a depth of kilometers beneath the surface. According to seismic data, sedimentary rocks that are adjacent to the Yangsan fault are thin and getting thicker towards the east of the section. In this study we also suggest a new method to recognize faults using core loggings. This analysis could be used to estimate fault locations at different scales.

By philological geography method for dismantling and reconstituting Buyeo's Palkyung(扶餘 八景), which best signify the image of ancient city Buyeo's landscape, this research is to demonstrate the fact that the place's inertia of certain historic sites has been passed down as a type of geographic code. Titled poems and retrospective poems about Buyeo's Palkyung and its spectacles and landscapes reveal the fact that the splendid and glorious cultural heritage of Baekje had faded but its traces have remained in the each eight views including Nakhwa-am(落花巖), Goran-sa(皐蘭寺), and Jayong-dae(釣龍臺). In addtion, the spectacles and historic sites of Buyeo's Palkyung appear as the symbol of Baekje's fall and loss in the poems. Thus, it can be said that Buyeo's culture and civilization have never escaped from the cultural and historical scars of Baekhe's fall, being dominated by the place's inertia originated from the identity as "Baekje'slastcapital". It is ironical that Buyeo's future development and prosperity are not free from its cultural and historical spectacles which bear the image of the fall of Baekje. 'Older Buyeos' Palkyung(扶餘舊八景)' and, Prior Buyeo's Palkyung(夫餘前八景), originate from nine views of an unknown builder and after the construction of pavilions and towers, 'Subuk-jeong eight views(水北亭八景)' by Heungguk Kim(金興國) and the eight poems of the, Retrospect of Buyeo(扶餘懷古八景), were created. 'Buyeo's later Palkyung(扶餘後八景), which are especially free from the site's inertia are known to have expanded the scope of Buyeo's landscape by deliberately demonstrating spectacles and sites different from those of existing views. Nakhwa-am, Goran-sa, Joryong-dae, Songwal-dae(送月臺), Youngwal-dae(迎月臺), and Pyungje-tap(平濟塔) are all located within a one kilometer radius of Banwol-sung(半月城), Buyeo's palace and the Baekma river(白馬江), Daewang-po(大旺浦), Busan(浮山) in a two kilometers radius. Jaon-dae(自溫臺), Subuk-jeong(水北亭), and Gyuam-jin(窺岩津) are located within a three kilometers radius. Even Chunjeong-dae(天政臺), which are located within a four kilometers radius of Banwol-sung are located alongside the Baekma river. This indicates the fact that these spectacles had not been established temporarily or impromptu but for a long period time by historic retrospect and the inertia of landscape's geographic cycle. In conclusion, the geographic phenomenon of historical and cultural inertia appeared because Buyeo had the geographic message of "fallen, ancient city". Therefore, Buyeo's Palkyung which have constant retrospective inertia is clearly an geographic code effective and helpful to understand not only the characteristics of historic sites and spectacles of Buyeo in the Sabi period but also the quality of the site itself.

The cases of unidentified individual remains submitted to Forensic dentistry section in National Institute of Scientific Investigation, Korea were analyzed to study the application of forensic dental identification into individual identification in the period 2002-2005. The identification cases of unidentified remains were 405 out of 493, which accounted about 82% of whole cases. The incidence of submission of skeletons at least including the skull was increased from 58% in 2002 to 80% in 2005. The numbers of cases for the full examinations were 4 times more than that for age estimation in 2005. Twenty-four cases were submitted for skull to photographic superimposition and 15 out of 24 cases were examined, and the other 9 cases were examined by DNA analysis only. The submitted cases for dental comparison were 23 cases, 9 cases were positively identified, 4 cases were possible, 7 cases were excluded, and 3 cases ended up with insufficient evidences. The proportion of positive identification by dental methods was increased gradually from 9% in 2002 to 46% in 2005. Forensic dental identification has become important and useful because the availability of dental records and radiographs has been increasing. Compared to DNA analysis, forensic dental identification has several advantages such as no needs for high cost equipments and low expenses. And the interpretation of results is straightforward and speedy. These advantages are based on using primary their own dental records of the individuals rather than secondary DNA reference samples from family members. The application of the forensic dental identification to unidentified individual remains will be increased because the dental comparison can complement the limitation of DNA analysis and skull to photographic superimposition in many cases. In order to obtain positive identifications of unidentified remains, a close collaboration between the police and forensic scientists is important. The systemic approach including legislation to preserve dental records of unidentified remains and missing persons for the identification of unidentified remains should be needed.

This study investigates the relationship between South Korean youths' Confucian values and sense of citizen ethics while presenting outlook on the sense of citizen ethics based on the theory of human nature. The purpose of this study, by doing so, is to present educational measures. For this purpose, empirical research method was applied in this study. In the empirical study, youths were surveyed and the answers were statistically analyzed and discussed with a view to achieve the study purpose. In the empirical research part of the study, Korean youths' awareness on Confucian values was examined along with its relationship with the sense of citizen ethics. The effect of Confucian values on sense of citizen ethics and their relationship were analyzed to evaluate the receptivity of youths on Confucian ideas and usefulness of sense of citizen ethics. This study investigated a total of final 311 sets of data from male and female students at middle and high schools located in Seoul, Gyeonggi, South Korea. First, to identify the youths' Confucian values and level of sense of citizen ethics, descriptive statistical analysis was conducted. As a result, the survey subjects were found to have, concerning the Confucian values, world view M=3.54, human relations view M=3.66, morality cultivation M=3.76, and social order M=3.45, higher than 3.0 to represent positive levels. The morality cultivation, in particular, was recorded the highest among all whereas the social order was relatively lower, which represents the degree of relying on Confucian values to establish social order. Second, the sub-variables of Confucian values were verified according to the personal characteristics of the surveyed youths and differences in their entire perception was investigated. As a result, according to gender, morality cultivation was found higher in female students (M=3.85) than in male students (M=3.64). According to the subjective economic level of their household, world view was found higher in upper class (M=3.98) than middle-low class (M=3.25) and low class (M=3.22) while human relations view was found higher in middle-upper class (M=3.79) than low class (M=3.46). As for the family type, morality cultivation was found higher in extended family (M=3.83) than nuclear family (M=3.62); and social order was higher in extended family (M=3.54) than nuclear family (M=3.36). Third, to verify the study theme of identifying the effects of youths' Confucian values on sense of citizen morality, hierarchical regression analysis was employed in this study, which used the multi-level model of multiple regression analysis. As a result, the Confucian values was found to have significant positive (+) correlations with the entire sense of citizen ethics in order of human relations view(${\beta}=.499$), world view(${\beta}=.412$), social order(${\beta}=.341$), and morality cultivation(${\beta}=.241$). Confucian value showed significant positive (+) correlations with autonomy in order of morality cultivation(${\beta}=.458$), human relations view(${\beta}=.454$), social order(${\beta}=.362$), and world view(${\beta}=.158$). Confucian values was found to have significant positive (+) correlations with community spirit in order of human relations view(${\beta}=.295$), social order(${\beta}=.281$), and morality cultivation(${\beta}=.232$). As shown in the findings above, youths' Confucian values was found to have significant positive (+) effects on the sense of citizen ethics. It is noted that the higher the Confucian values, the more positive the sense of citizen ethics would be. Consequentially, the Confucian values was identified to play an important role in the sense of citizen ethics in the modern society. Based on this analysis, this study presented specific measures - the necessity and possibility of education on sense of citizen ethics under the theory of human nature. To this end, this study proposed to find an optimal interface between the contemporary sense of citizen ethics and Confucian ethics through the respect for human life and nature, man of virtue as the ideal human model, and united society as a desirable society model.

Purpose : The proliferative nuclear antigen Ki-67, present in all cell cycle phases except G0, is a useful marker for the detection of proliferative cells in vivo. MIB I has been found to recognize an antigen in formalin-fixed and wax-embedded material. The aim of this study was to assess the efficacy of MIB-1 expression as a marker of representing the status of mesangial cell proliferation in renal tissues. Methods : Immunohistochemical staining for Ki-67 Ag using monoclonal antibody MIB-1 (Immunotech,505) were performed in 41 renal tissuses which were obtained by percutaneous renal biopsy done between January 1994 and December 1996. Results : In both glomeruli and renal tubules, MIB-1 expression was observed only in 2 of 18 ($11.1\%$) cases of IgA nephropathy, in 2 of the 4 ($50\%$) cases of mebranoproliferative glomerulonephritis, in 4 of the 5 ($80\%$) cases of poststreptococcal glomerulonephritis. But MIB-1 expression was not detected in all cases of minimal lesion and membranous nephropathy. Renal tubules In another 7 cases of IgA nephropathy were MIB-1 positive. Conclusion : MIB-1 expression in renal tissues may relate to the cell proliferation in glomeruli and renal tubules. But the efficacy of MIB-1 expression as a marker of mesangial cell proliferation may reveal a limited value because of it's lower positive rate in IgA nephropathy.

We have numerous terms representing mind. We can understand them largely as the relationship of 'Discernible Mind' and 'Indiscernible Mind.' Because, our understanding mind is formed by linguistic discernment. When any discernment arise from our mind, we recognize the mind shown by discernment[Discernible Mind]. At the same time, we can think orignal mind[Indiscernible Mind] outside that discernment. Buddhism, generally, has understood mind in the relation with everything. That is to say, they have understood it from the perspective of dependent co-arising. In the early Buddhism and the abhidharma Buddhism, approaches to mind were mainly made by the discerning method. They explained arising and vanishing of 'Discernible Mind' by the law of dependent arising. Co-arisen 'Discernible Mind' is impermanent and temporary. But they never be denied on 'Discernible Mind' as an vainness. In $Mah{\bar{a}}y{\bar{a}}na$ Buddhism, $N{\bar{a}}garjuna$ understood the essence of dependent arising as the ${\acute{s}}{\bar{u}}nyata$ (emptiness) and the law of dependent arising as simultaneous dependence, not gradual dependences. $N{\bar{a}}garjuna$ criticized on vainness of Discernible Mind through ${\acute{s}}{\bar{u}}nyata$, and made possible to directly perceive Indiscernible Mind, before Discernment. Undiscriminating Mind can not be explained for being stayed beyond the state linguistic discernment(false discrimination), however, had been approached from various other names to potential consciousness or original nature. While ${\acute{s}}{\bar{u}}nata$ thought focused on criticizing vainness of discernment, Hwaeum thought suggested aspect of Indiscernible mind from the aspect of $ekay{\bar{a}}na$ dependant co-arising that everything has been co-arisen, the truth of discrimination. Furthermore, it opened the path to affirm the both indiscernible mind and discernible mind by illuminating that everything is manifestation of original nature itself, i.e. nature-arising. Hwaeum thought focused on perfect understanding by explicating the relation both indiscernible mind and discernible mind from the view point of non-abiding, rather than clarifying 'Discernible Mind' and 'Indiscernible Mind', itself. That is to say, from the aspect of dependant co-arising, Hwaeum thought plays a role that enters the indiscernible world from discernible world, and also, another role, from the aspect of nature-arising that is manifesting discernible world from indiscernible world. These aspects are important for righteous understanding on mind, and also simultaneously, very effective for healing disease of obsession, a kind of metal disease.

Until recently, research trend in real estate has been focused on real estate market and the market analysis. But the studies on real estate training program development for real estate agents to improve their job performance are relatively short in numbers. Thus, this study shows empirical analysis of the needs for the training programs for real estate agents in Cheonan to improve their job performance. The results are as follows. First, in the survey of asking what educational contents they need in order to improve real estate agents' job performance, most of the respondents show their needs for the analysis of house's value, legal knowledge, real estate management, accounting, real estate marketing, and understanding of the real estate policy. This is because they are well aware that the best way of responding to the changing clients' needs comes from training programs. Secondly, asked about real estate marketing strategies, most of respondents showed their awareness of new strategies to meet the needs of clients. This is because new forms of marketing strategies including internet ads are needed in the field as the paradigm including Information Technology changes. Thirdly, asked about the need for real estate-related training programs, 92% of the respondents answered they need real estate education programs run by the continuing education centers of the universities. In addition, the survey showed their needs for retraining programs that utilize the resources in the local universities. Other than this, to have effective and efficient training programs, they demanded running a training system by utilizing the human resources of the universities under the name of the department of 'Real Estate Contract' for real estate agents' job performance. Fourthly, the survey revealed real estate management(44.2%) and real estate marketing(42.3%) is the most chosen contents they want to take in the regular course for improving real estate agents' job performance. This shows their will to understand clients' needs through the mind of real estate management and real estate marketing. The survey showed they prefer the training programs as an irregular course to those in the regular one. Despite the above results, this study chose subjects only in Cheanan and thus it needs to research more diverse areas. The needs of programs to improve real estate agents job performance should be analyzed empirically targeting the real estate agents not just in Cheonan but also cities like Pyeongchon, Ilsan and Bundang in which real estate business is booming, as well as undergraduate and graduate students whose major is real estate studies. These studies will be able to provide information to help develop the customized training programs by evaluating elements that real estate agents need in order to meet clients satisfaction and improve their job performance. Many variables of the program development learned through these studies can be incorporated in the curriculum of the real estate studies and used very practically as information for the development of the real estate studies in this fast changing era.

Quantitative determination of the protein expression levels is one of the most important parts in assessment of the safety of foods derived from genetically modified (GM) crops. Overexpression of AtCYP78A7, a gene encoding cytochrome P450 protein, has been reported to improve tolerance to abiotic stress, such as drought and salt stress, in transgenic rice (Oryza sativa L.). In the present study, an enzyme-linked immunosorbent assay (ELISA) kit for diagnosing AtCYP78A7 protein including AtCYP78A7-specific monoclonal antibody was developed. GST-AtCYP78A7 recombinant protein was induced and purified by affinity column. Four monoclonal antibodies (mAb 6A7, mAb 4C2, mAb 11H6, and mAb 7E8) against recombinant protein were also produced and biotinylated with avidin-HRP. After pairing test using GST-AtCYP78A7 protein and lysate of rice samples, mAb 4C2 and mAb 7E8 were selected as a capture antibody and a detecting antibody, respectively, for ELISA kit. Product test using rice samples indicated that percentages of detected protein in total protein were greater than 0.1% in AtCYP78A7-overexpressing transgenic rice (Line 10B-5 and 18A-4), whereas those in negative control non-transgenic rice (Ilpum and Hwayoung) were less than 0.1%. The ELISA kit developed in this study can be useful for the rapid detection and safety assessment of transgenic rice overexpressing AtCYP78A7.

This study contributes to understanding women's labor market behavior by focusing on a particular set of labor force transitions - labor force withdrawal and entry during the period surrounding the first birth of a child. In particular, this study provides a dynamic analyses, using longitudinal data and event history analysis, to conceptualize labor force behaviors in a straightforward way. The main research question addresses which factors increase or decrease the hazard rates of leaving and entering the labor market. This study used piecewise Gompertz model, following the guide of the non-parametric analysis on the hazard rates, which allowed relatively detailed description on the distribution of timing of leave and entry to the labor market as parameters of interest. The results show that preferences and structural variables, as well as economic considerations, are very important factors to explain the labor market behavior of women in the period surrounding childbirth.
