Many biologists and various educational associations define evolution as a unifying theme as well as a central idea in biology. In this study, teacher education programs were developed as 18-hour courses on understanding the unified role and significance of evolution in biology, and their effectiveness was tested. As factors for the program content, enhancement of the acceptance of evolution, reinforcement of the conception of evolutionary theory, and recognizing and practicing evolution as the unifying nature of evolution were considered. Hands-on activities, self- and peer-evaluation, and projects based on the small teams including frequent questioning and feedback by instructors were considered methodological factors. Six in-service biology teachers and seven pre-service teachers took part in the programs of the graduate school of H university to testing their effectiveness. They were effective in improving the acceptance of evolution, the understanding of evolutionary mechanism, the perception on the unified role of evolution. The programs also induced a positive change in self-evaluation for knowledge of evolution and perception on importance of evolution in biology. Subsequent studies on whether the changed perceptions of the teachers who participated in the programs reflect on their biology classes in secondary schools after finishing the graduate program are required.

The purpose of this study was to compare the replicability of centric relation made by means of self guided method, bimanual manipulation, chin-point guidance, leaf gauge method, gothic arch tracing. The EPA test of Arcus $Digma^{(R)}$ was employed for examining the reproducibility of centric relation. 10 adults with normal occlusion were participated in this study. In this limitation of study, the following results were obtained; Condyle position was different depending on different methods of guiding centric relation. Left and right temporomandibular joints showed a little different degree of repeatability. Bimanual manipulation using anterior jig was the most replicable. Chin point guidance provided the second most repeatable method, and Gothic arch tracing showed the third, the leaf gauge was the forth, the self-guided method was the worst.

지난 6월 3일 동경에서 있었던, 아시아 항공/우주법 학술대회 제 3분과에서 영국 Bin Cheng교수의 "The Warsaw System: Mess up, Tear up, or Shore up?"이라는 주제의 논문발표가 있었다. Bin Cheng교수는 특히 유럽의 EC Consultant Paper 와 일본항공사들의 1992년의 무한책임보상주의 채택에 대하여, 마치 무한 책임보상주의의 이론이 승리하였으며, 위의 상황들이 그 시작이라고 단정하였는데 이러한 견해는 아직까지 시기상조라고 생각한다. 본 글에서는 동경회의에서의 Bin Cheng교수의 논문중 특히 10항의 결론 부분을 중점으로 반대되는 의견을 제시하고자 한다. 국제항공사법인 와르소체제가 과연 발전하고 있는 것인가? 퇴보하고 있는 것인가? 와르소체제의 반대론자들은 미국의 소송변호사들, 일본항공사들과 일부 순수이론을 고수하는 학자들로써 이들은 와르소체제로부터의 탈퇴와 무한책임보상주의를 고수하고 있다. EC Consultation Paper (각주 122 참조)에서 보듯이, 비록 항공운송시의 손해배상액이 타 운송시의 손해배상액보다 적기는 하지만 이것이 곧 '무한책임보상주의'를 의미하는 것은 아니다. 미국의 판례중 불법행위로 인한 소송 (Nichole Fortman v. Hemeo Inc.)에서 보면, 작은 창자의 대부분을 병원의 과실때문에 잃은 Brooklin의 한 여인에게 500억 정도의 손해배상이 주어진 것을 보면, 과연 완전 보상에 맞는 무한책임이 과연 항공소송에 적용될 수 있는 것인가를 알아야 한다. 무한책임보상주의는 특히 개발도상국의 항공사들에게 보험료가 너무 과중하고, 와르소협약의 근본목적인 국제항공법의 통일성에 반하고 있기 때문에 국제사회 전반에 적용하기에는 비현실적이다. 와르소체제의 통일 성에 대한 거부는 만약 와르소체제에 버금가는 다른 보상체제가 있는 경우에는 다르지만, 현실적으로는 결국 국제적 혼란만을 야기사킬 것이다. 또한 와르소체제 반대자들은 항공운송인과 승객들의 관계를 갈등관계로 보고 있지만, 근본적으로 와프소협약에서의 항공운송인파 승객들의 관제는 공동이악관계로 보아야 한다. 항공운송사업의 목적도 또한 이윤추구인 바, 승객들이 항공운송인에게 과다한 손해배상을 요구하면, 결국 항공운송인은 승객들의 주머니에서 그 댓가를 찾으려고 할 것이다. 절국 양자의 이익을 보는 것은 소송변호사들 뿐이라고 볼 수 있다. 또한 'Unlimited Liability' 에서 'Unlimited' 란 'Full-Compensation' 을 의미하는 것으로, 'Wilful-Misconduct' 의 경우에는, 'Full-Compensation' 의 개념과 다르게, 그 보상액이 Warsaw협약 제 22조 1항에 적용되지 않는 'No-limited' 의 개념으로 해석하여야 한다. 항공소송의 경우에 통상 'Wilful-Misconduct' 의 경우에 손해배상액이 약 $700,000 인 것을 보더라도 'Full-Compensation'의 의미로 해석할 수 없다. 몬트리올 제 3추가의정서에서 'WilfulMisconduct' 의 개념을 삭제하고자 하는 것은, 이에 대비하여 추가보상제도, 임액수의 종액, 영격책임추의 등의 요소들을 전제로 하고 있기 때문이다. 몬트리올 제 3추가의정서가 최근의 발전적인 손해배상제도인가에 대하여, Bin Cheng 교수는 반대를 하고 있지만, 최선의 제도를 찾는 입장에서 몬트리올 추가 의정서는 여러가지로 부족하다. 그러나, 유한책임제도의 개선, 엄격책임주의의 도입, 빠른 소송타결의 제도, 재판관할권의 확대 그리고, SDR 화폐단위의 채택 등은 헤이그 의정서 이후의 보다 나은 제도적 장치를 하고 있다고 해석하여야 할 것이다. 시대의 변화에 따라 점진적으로 발전된 보상제도를 채택하였다면, 오늘날과 같이 시대에 뒤떨어진 보상체제로 혼란을 겪고 있지 않았을 것이다.

Amelogenesis imperfecta (AI) occurs either in isolation or in association with other dental abnormalities and systemic disorder. A rare syndrome associating AI with nephrocalcinosis was named as Enamel Renal Syndrome (ERS; OMIM #204690). This syndrome is characterized by severe enamel hypoplasia, failed tooth eruption, intra pulpal calcifications, enlarged gingiva, and nephrocalcinosis. Nephrocalcinosis is a condition where calcium salts are deposited in renal tissue, and this may lead to critical kidney complications. This rare syndrome shows pathognomonic oral characteristics that are easily detectable at an early age, which proceeds the onset of renal involvement. Pediatric dentists are the first oral health practitioners whom ERS patients will meet at early age. The role of pediatric dentists is critically important for early diagnosis and referral of patients to both nephrologists for renal assessment and geneticists for identification of causative mutation and diagnosis. Early detection of renal involvement may provide chances to prevent further undesired renal complications.

This article is the critical review of the methods and assumptions with which the Korean archaeologists have tried to approach to the Bronze age society. It was not until the 1980s' that there had been any attempt to define the relevant units for the study of past societies. Before the archaeological records of megalithic builders in the Bronze age began to be analyzed to find out the general traits of chiefdom society, Korean archaeologists had described the variations in the cultural, rather than the social, entities. From the 1990s' , some scholars have attempted to reconstruct the scale and organization of the social groups and explain the growth of polities in evolutionary view, analyzing the hierarchical distributions of settlement data. In the concluding remarks of the review, I would like to indicate the some problems in the conceptualization of the material culture patterning in the regional and/or inter-regional level. First, the conceptual problem which appeared when the Bronze archaeologists define the distribution of artifact assemblages, composed of the specific artifact traits , beyond the instrumental categories that are efficient for the establishments of regional chronologies. It is evidently erroneous conceptualization that we define the artifact assemblages as the socio-cultual entities which came into being in specific time and place, geographically expanded, and finally disappeared based on the view of essentialism. Second, the interpretative problems about wide distributions of certain bronze artifacts must be indicated. I would like to suggest that the wide distributions of the specific bronze dagger or mirror types should be explained not by the cultural area concept related to the ethnicity assumptions, but by the world system or the inter-regional interaction models.

The purpose of this paper is to examine the relationship between entrepreneurship and management with respect to research and education. There has been scholars who argue entrepreneurship is, and should be, different from management. Most famous example is Shane, who strongly advocate the distinct domain of entrepreneurship clearly distinguishable from (strategic) management. In spite of the argument, it is true that in most universities, entrepreneurship research and education are encompassed as part of a business school. In Korea, however, where entrepreneurship education has been supported and in part led by government, the situation is different. In this paper, we examine such phenomena and then investigate the related papers published in Korea since 2000. We categorized the papers according to the research context, theory and methodology adopted, and variables used for empirical study. The result illustrate that there exist a substantial number of entrepreneurship papers, distinguishable from management papers, focusing the narrow topic of 'entrepreneurial intention'. However, the other papers with titles or keyword of entrepreneurship are on the borderline of entrepreneurship and management. Futhermore, in-depth research on the entrepreneurial process which is often argued as unique topic of entrepreneurial research is very rare. Therefore, the quantity and quality of future study on the entrepreneurial process will be the touchstone to judge whether or not the entrepreneurship and management are differentiated.

The soil on the behavior of the nonlinear elastic work-hardening plasticity has a variety of stress paths due to the state of soil and the test conditions. The soil with a specific volume ${\upsilon}$ in principal stress space (${\sigma}_1$, ${\sigma}_2$, ${\sigma}_3$, and ${\upsilon}$v) displays the shape of an irregular hexagonal pyramid with an end cap. With variations of ${\upsilon}$ the size of the cap is changed but its shape remains unchanged and the movement of the cap is controlled by the increase or decrease of the plastic volumetric strain. By reflecting such a property of soil various cap models have been developed by researchers. In this thesis, a constitutive model of soil with a combination of the nonlinear elastic work-hardening plastic cap and the failure surfaces of Mohr-Coulomb (M-C cap model) has been developed. According to the the results of analyses using the work-hardening plastic cap model, the normally consolidated soil under shearing has experienced the work-hardening and plastic flow (movement of the cap). But in the shearing of the overconsolidated soil the elastic behavior is shown until the stress path has reached the failure surface and the cap does not move.

According to outstanding maritime economists from domestic and overseas, shipping lines or ships' enlargement reduce fixed costs, and assist realization of scale of economy of shipping. On the contrary, recent Korean liquidity crisis on the shipping lines (SL) has been focused on the leading companies such as Hanjin Shipping (HJS), Korealines, and STX Pan Ocean. In this respect, this study aims to review Korean SLs' strategies and suggest the optimal solution between the specialization and enlargement. For these purposes, this research adopts slack based measure data envelopment analysis (SBM-DEA) model as a research methodology. As for decision making units (DMUs), SLs which have increased the vessel numbers and belonged to top tier group in year 2013, are selected. The results are comprised with two aspects. Firstly, HJS, KMTC, Korea LNG Trading (KLT), EUKOR, and Sinokor Tanker show the most efficient in regard to constant return to scale (CRS) model. Secondly, HJS, KMTC, KLT, Daerim, Chungang, Sinnokor Tanker, and EUKOR are the most efficient companies in terms of variable return to scale (VRS) model. Lastly, these results could be affected to the management philosophy and can answer the following question. Which is the most optimized SL?s management decision making, enlargement or specialization?

DNA polymorphisms were analyzed for 8 clones of the green peach aphid, Myzus persicae Sulzer, by random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR). The insect has different host preferences and was even classified into two different species, M. persicae Sulzer and Myzus nicotinae Blackman by their morphological characters, but this point is still in arguement. To identify the differences between two types of the green peach aphid by RAPD-PCR, the template DNA was extracted from 4 clones each of tobacco-feeding and non-tobacco-feeding forms and one hundred primers of 10-nucleotideslong were tested in PCR. The amplified DNAs were analyzed by agarose gel electrophoresis. Eighty-three primers gave amplified DNA fragments with 1 to 22 in number and 500 to 20,000 base pairs in length, but no amplification was observed in the other 17 primers. The average number of fragment per each amplification was about 13. In the case of 82 out of 83 random primers, band patterns of amplified DNA were identical among 8 clones, even though some differences were noticed in the intensity of specific bands. Polymorphism was detected by only one primer within the tobacco-feeding forms, but not between the two host types. The results did not detect any relationship between RAPD polymorphism and their host preference.

RAPD analyses were compared for 17 taxa of Korean Iris including the subgenus Sisyrinchium and Belamcanda. Eighty scorable RAPD markers were formed from the PCR reactions using 10 random oligoprimers. In this systematic analyses which used neighbor-joining methods including bootstrapping analyses with genetic coefficients, the Korean Iris were divided into three subgenera (Limniris, Crossiris, Pardanthopsis), or two genera (Limniris, Pardanthopsis). The molecular data agree with the previous classification system that recognized two sections and six series for the subgenus Limniris because the subgenus is comprised of four clades in the RAPD analyses. According to the molecula data, the series Chinensis should be divided into two groups. The minutoaurea group is composed of I. koreana, I. odaesanensis, and I. minitoaurea, while the rossi group is comprised of two varieties of I. rossi. The series Tripetalae is closely allied with the series Sibiricae, whereas the series Ensatae is recognized as a sister group to the series Ruthencae. The molecular phylogeny, which was based on RAPD analysis, for the most part agreed with the data proposed by previous authors. This is because the basis of morphological and ITS sequence data suggests that the RAPD markers should be very useful in addressing phylogenetic questions about the genus Iris.
