1 In the first paper “Determinants of Corporate Ownership Structure and their effects on Corporate Governance in South Korea” by Shin-Il Kang, Korea’s unique characteristics, specifically the ownership structure and corporate governance are examined. The author takes a broad perspective by incorporating corporate culture, business leadership, and ownership structure in Korean corporation. Furthermore, he discusses the substitutability of Korean specific features given the rapidly changing economic environment. Under the Korea’s Chaebol structure, controlling shareholders, who are the real owner of firms, have exercised ownership rights while having a large proportion of shares aided by cross shareholdings. This has been possible through the pyramid ownership control structure as well as cross-shareholding among subsidiaries. Market circumstances related to management costs are not favorable to the firm with a dispersed ownership structure. In Korea, that’s the reason why ownership is concentrated. Given such a structure, the owners minimize costs related to management’s risks. Furthermore it proposes that leadership(firm culture) and ownership are substitutes. Concentrated ownership is needed when the leadership is not mature like Korean Chaebol. 2 The second paper “Issues in Japanese Corporate Governance” by Peter Drysdale examines some of the major issues of Japanese corporate governance today. The role of that main bank in corporate governance and inter corporate shareholding has been well documented. Although Japanese banks have rigorously monitored firms and have had an enormous influence on firms’ decisions and strategies through the owning of shares, firm performance under such a main bank system has not always been positive. Opposing views and their rationale regarding the pessimism behind the performance of firms in the main bank system are also explained in this paper. 3 The paper “Corporate Governance in China” by In Kie Hong discusses the current status and the restructuring efforts of China’s corporate governance. In China, state shareholders possess strong control rights over listed companies allowing them to exercise control even beyond their proportion of shareholding. Various governmental organizations(under the Communist Party) acting as representatives of the state as shareholders have influenced firms enormously, particularly regarding matters of organizing the board of directors as well as electing management. However since they have little incentives to manage state(national) assets and have insufficient capacity to monitor a large number of firms of which they are in charge, the principal-agent problem tends to prevail, which adds to the difficulties in preserving the value of state assets as well. 4 The last paper “Ownership Concentration and Corporate Performances in the Northeast Asian Countries” by Seung-Rok Park compares the relationship between corporate governance structure and corporate performance in Korea, Japan, and China by empirically examining the accounting corporate performances and technical efficiency measures. In the case of Korea, ownership concentration was shown to have positively affected all corporate accounting performance variables such as profit margin, return on shareholders’ funds, return on total assets, and return on capital employed. Furthermore, it was also found that ownership concentration positively affected corporate performance by helping improve the technical efficiency of firms. Unlike Korea, in Japan, there was no sign of a positive effect of ownership concentration on the accounting corporate performance and technical efficiency. Moreover, in the case of China, ownership concentration positively affected profit margin and return on total assets, while no positive effects of ownership concentration were found on return on capital employed and return on shareholders’ funds. It is shown in this study that the difference in the rel

Comparative AFLP Profiles among Strains of Korean Races of Xanthomonas oryzae pv. oryzae.

Kang,Mi-Hyung,Lee,Du-Ku,Noh,Tae-Hwan,Shim,Hyeong-Kwon,Na,Seung-Yong,Kim,Jae-Duk 한국자원식물학회 2004 Plant Resources Vol.7 No.1

We used an amplified fragment length polymorphism (AFLP) analysis, a novel PCR-based technique, to differentiate Xanthomonas oryzae pv. oryzae (Xoo) of Korean races. The 6 strains of Xoo K1, K2, K3 races were tested with 81 AFLP primer combinations to identify the best selective primers. The primer combinations were selected according to their reproducibility, number of polymorphic bands and polymorphism detected among Xoo strains. 18 strains of Xoo K1, K2 and K3 races were analyzed with the selected combinations of primer set. Some primer combinations (Eco R I +1 / Mse I+1) could differentiate Xoo of Korean races that were not distinguished by other fingerprinting analysis. Thus AFLP fingerprinting permitted very fine discrimination among different races.

Simplified Effective Compressive Strengths of Columns with Intervening Floor Slabs

Seung?Ho Choi,Jin?Ha Hwang,Sun?Jin Han,Hae?Chang Cho,Jae Hyun Kim,Kang Su Kim 한국콘크리트학회 2020 International Journal of Concrete Structures and M Vol.14 No.5

The current design codes discuss the effective compressive strengths of columns, which reflect a decrease in load transfer performance that can occur when columns and slabs have different concrete compressive strengths. The effective compressive strength of a column increases as it is confined by the slab, and the design codes mandate three different effective compressive strengths for interior columns (confinement on four sides), exterior columns (confinement on three sides), and corner columns (confinement on two sides). For both corner and exterior columns, the confinement effect of the slab is significantly smaller than that for the interior column, and there is a more marked decrease in load transfer performance. However, there is still a lack of theoretical studies investigating the effective compressive strengths of the corner and exterior columns. Therefore, based on the analysis model established in previous research, this study has proposed an equation for calculating the effective compressive strengths of the corner, exterior and isolated columns without any confinement effects of the slab. In addition, axial loading tests of isolated columns were conducted and the proposed equation was verified.

Kingship in Kassite Babylonia Kang, Seung-Il From the beginning of the sixteenth century B.C.E., the Near East entered into a so-called Dark Age. The most important historical development in southern Mesopotamia during this period is the ascendancy of a new people, the Kassites. As king of a territorial state in contrast with the former rulers of city states, the Kassite kings ruled over Babylonia for almost half a millenium and led the country into one of the members of the Great Powers` Club in the ancient Near East. Yet it is very difficult to reconstruct the administration and kingship during the Kassite dynasty with any degree of certainty. The problem lies with the nature of the sources. Only a small portion of some twelve thousand Kassite documents has been published so far and most of them are economic ones relating to Nippur. The dearth of pertinent documentation hampers our effort to articulate many aspects of kingship of the Kassite rulers. This paper discusses some important features of the kings of the Kassite dynasty in Babylonia from the sparse material avaliable to us. The most distinctive feature of the Kassite kingship is the adoption of the traditional Babylonian culture. Knowing that they could not easily overturn the deep-rooted and more advanced traditional Babylonian culture, the Kassite rulers tried to acquire the native Babylonians` hearts and minds by advocating and promoting the traditional Babylonian cults. They restored, repaired, or built temples throughout all important cities. The Kassites also preserved the Babylonian scribal tradition and existing literary and scholarly texts. Thanks to their encompassing policy, Kassite Babylonia could become a place of blossoming Standard Babylonian literary production and the Babylonian language became the lingua franca of the ancient Near East.

그림책은 언어와 그림이라는 두 가지 서로 다른 매체가 결합하여 의미를 전달하는 독특한 의사소통의 수단이자 글과 그림이 어우러진 새로운 예술형식이다. 또한 그림책은 어린이가 접하는 최초의 책으로 오늘날 많은 어린이에게 보편화된 교육매체이다. 따라서 본 논문은 어린이와 그림책을 교육 인간학적 관점에서 체계적으로 이해하고, 그림책을 통해 어린이 존재의 사고 특징을 고찰하고자 하였으며, 이에 근거하여 어린이 그림책의 교육인간학적 의의를 탐색하고자 하였다. 그림책에 반영된 어린이 사고의 특징을 살펴보면, 어린이는 물활론적 사고, 환상적 사고, 모험적 사고를 하는 존재로서, 어린이의 다양한 사고는 유기적 결합에 의해 상호연관을 가지며 발달해감을 알 수 있었다. 이러한 논의를 바탕으로 어린이 그림책의 교육인간학적 의의를 제시하면, 우선 어린이 그림책은 어린이에 대한 깊은 이해가 가능하게 하였으며, 어린이에게 풍부한 경험을 제공한다. 또한 어린이 그림책은 어린이의 관계형성에 기여하며, 어린이의 주체적인 자아형성의 토대를 마련해 준다. Picture books are a unique communicative tool and a new kind of art in which letters and pictures are combined. Picture books are also a popularized educational medium in teaching children how to read. Therefore, the picture book is, for children, a literary, artistic, and educational resource. This study explores the strategies of how picture books can be used for children`s education by understanding the essential characters of picture books and the relationship between children and picture books. The study finds that children engage in animistic, fantastic and adventurous thinking. Through analyzing the characteristics of children`s thinking reflected in children`s books, the study finds these three characteristics are interwoven and children`s thinking develops in this interwoven relationship. The educational-anthropological significance of children`s picture books is as follows: Firstly, picture books enable educators to understand children and to show a concrete direction of children`s education. Secondly, picture books provide an aesthetic experience to make children aware of beauty. They also serve as a foundation for children`s relationships and shape each child`s independent self. The author suggests this is the educational task of the picture books. In order to promote the authentic education of children through picture books, it is crucial to recognize the educational importance of the picture book. It is also necessary to foster an environment that is conducive for children to read picture books and to encourage self-motivated reading. It is necessary to study various aspects of children`s picture books in order to produce good quality picture books.

기주특이적 독소 생성 Alternaria spp.와 비병원성 A. alternata의 계통분류학적 유연관계를 규명하기 위하여 기주특이적 독소 생성 Alternaria 6균, 비병원성인 A. alternata 그리고 비교균으로서 소형포자를 형성하는 A. brassicicola, 대형포자를 형성하는 A. solani의 ribosmal DNA의 5.8S를 포함한 ITS영역의 염기 서열을 분석하였던 바 다음과 같은 결과를 얻었다. 1. Alternaria spp.의 rDNA ITS영역의 염기서열 크기는 548∼562bp였으며 5.8S rDNA에서는 비교종간에 서로 일치하였고 ITS I에서는 종간 뚜렷한 차이를 보였다. 2. 기주특이적 독소 생성 Alternaria spp.의 rDNA의 ITS영역의 염기서열은 비병원성인 A. alternata의 염기서열과는 서로 일치하였으나 A. brassicicola와는 3%, A. solani와는 7%의 염기서열 차를 보였다. 3. 기주특이적 독소 생성 Alternaria spp.는 비병원성 A. alternata와 진화적으로 매우 가까운 유연관계를 나타내었다. The regions of internal transcribed spacer(ITS) including 5.8S ribosomal DNA(rDXA) from six host-specific toxin(HST) producing Alternaria spp. nonpathogenic A. alternata. A. solani and A. brassicicola were sequenced to assess their relationship in taxonomy. There was no difference in the sequences of ITS including 5.8S rDNA among the HST-producing Alternaria spp. and nonpathogenic A. alternata. However, the sequences of HST-producing Alternaria spp. were different from those of A. solani and A. brassicicola by about 7% and 3%, respectively. These results suggest that HST-producing Alternaria spp. are evolutionarily very close to non pathogenic A. alternata although they have host-specific pathogenecity.

It has been known that the shear strength of soil is an important design parameter for the foundation of structures, the retaining walls, the slope failures and so forth. In this study, the shear test was performed by using the direct shear apparatus under various degree of the moisture content and the density of the sample soils. The results of the study were summarized as follows; 1. The shear strength of soil increased with increase in the dry density of soil, and at the same level of density of the sample the shear strength of soil showed large values on a good grading of the sample. 2. The cohesion of the soil varied directly with the dry density of it, however the internal friction angle of soil was not affected by the dry density of the sample. 3. The shear strength of sample varied inversly with the moisture content of it, and this phenomenon was apparent on a good grading of sample. 4. The cohesion of soil showed maximum value when the moisture content of the soil reached optimum level and the internal friction angle decreased with increase in the moisture content of it. These phenomena were very obvious on a good grading sample, SDC-1. 5. The cohesion of the soil decreased with increase in void ratio of the sample, but the internal friction angle of the sample didn't show such tendency.

무선 애드 혹 기반 액티브네트워크상에서 QoS지원에 관한 연구

李基源,裵振勝,丁燦赫,金玄郁,李光培,姜景仁,朴京培,文泰洙,郭承郁,河載承 明知大學校 産業技術硏究所 2003 産業技術硏究所論文集 Vol.22 No.-

Abstract - In this thesis, we propose a QoS supporting method on wireless ad hoc-based active network for improving reliability. On the loss of route path, the existing DSR routing protocol has several problems with wireless network communication because of decease of data reception rate and increase of network load. The proposed method improves reliability of data transfer by using functions of active network. That is, by using functions of active nodes and active packets, the proposed method supports QoS with reservation transfer method that saves data packets on transfer at intermediate nodes with lost path and then re-transmit the packets after route reconfiguration.

( Sang Hoon Ahn ),( Won Hyeok Choe ),( Yoon Jun Kim ),( Jeong Heo ),( Dorota Latarska-smuga ),( Jiho Kang ),( Seung Woon Paik ) 대한간학회 2017 춘·추계 학술대회 (KASL) Vol.2017 No.1

Aims: Chronic Hepatitis C Virus (HCV) infection increases the risk for progressive liver disease, hepatocellular carcinoma and negatively impacts the patient’s quality of life. HCV treatment is evolving with direct acting antivirals but IFN based therapy has been the standard of care for many years and remains available in some countries. The MOSAIC study aims to characterize patients with chronic HCV infection and assess the impact of IFN-containing treatment on health-related quality of life, work related productivity and health care utilization. Methods: MOSAIC is an international prospective multicenter observational study that has been conducted in 20 countries. Consecutive patients with chronic HCV infection were enrolled and those who initiated an IFN based regimen were prospectively followed for 48 weeks. We report results from the Korean cohort Results: 100 patients were enrolled: 86 were treatment naïve and 14 were treatment experienced. 33 patients initiated an IFN based regimen: 6 patients started IFN + RBV, 26 patients started Peg-IFN + RBV, none started Peg-IFN + RBV + DAA and 1 patient received other treatment. Among the treated cohort, demographic and disease characteristics were the following: the mean age was 54.5 years; 14 patients were male. 14 had minimal or no fibrosis, 2 portal fibrosis, 3 bridging fibrosis and 6 patients suffered from cirrhosis. HCV Genotype distribution was as follows: genotype 1: 11; genotype 2: 19 and genotype 3: 3. Table 1 describes the results at baseline and changes over 4, 12 and 48 weeks and end-of-treatment (EOT) for the quality of life and work productivity outcome measures (EQ-5D-5L, HCV-PRO and WPAI). Conclusions: Results from the Korean cohort of the MOSAIC study show a moderate trend for deterioration of health-related quality of life and work productivity associated with IFN based treatment for patients with chronic HCV infection during treatment period.
