Purpose : To evaluate accuracy and reliability of program to measure facial soft tissue thickness using 3D computed tomographic images by comparing with direct measurement. Materials and Methods : One cadaver was scanned with a Helical CT with 3 mm slice thickness and 3 mm/sec table speed. The acquired data was reconstructed with 1.5 mm reconstruction interval and the images were transferred to a personal computer. The facial soft tissue thickness were measured using a program developed newly in 3D image. For direct measurement, the cadaver was cut with a bone cutter and then a ruler was placed above the cut side. The procedure was followed by taking pictures of the facial soft tissues with a high-resolution digital camera. Then the measurements were done in the photographic images and repeated for ten times. A repeated measure analysis of variance was adopted to compare and analyze the measurements resulting from the two different methods. Comparison according to the areas was analyzed by Mann-Whitney test. Results : There were no statistically significant differences between the direct measurements and those using the 3D images (p>0.05). There were statistical differences in the measurements on 17 points but all the points except 2 points showed a mean difference of 0.5 mm or less. Conclusion : The developed software program to measure the facial soft tissue thickness using 3D images was so accurate that it allows to measure facial soft tissues thickness more easily in forensic science and anthropology.

This study analyzed the ignorance and prejudice with regard to African culture, which can be seen at the textbook and class course centering the geography class from 1990's to the present, and reviewed critically the related education and learning effects for mutual understanding. This study results are as follows: First, in the geographic environment contents, the image regarding huge continent, the local image regarding the various physical environments and the geographical importance as the ancient civilization birthplace were not included in the description. Second, the description regarding the African culture and history was focused to the singular African image, so the fixed concept and distorted image has been rooted into the formation of cultural meta-knowledge. Third, the negative sides rather than positive development and the past backward facts rather than changed status have been emphasized in the description regarding African resources and industry as well, so only the region surrounded with the various problems including poverty and the image as underdeveloped country have been rooted into the description. Now, real Africa view, an image for a variety of attractive and vibrant Africa rather than the same culture and characteristics of African must be learned in text books.

Objective : Psychiatry in North Korea is believed to seem very different from psychiatry in South Korea. However, there is nearly no information regarding psychiatry in North Korea until now. Our study aimed to get information about North Korean psychiatry. Methods : Three North Korean defectors in South Korea, whose clinical experience as medical doctors in North Korea was over 10 years, were recruited. They underwent the semi-structured interview, content of which included the clinical experience with psychiatric patients, the details of psychiatry, the treatment of psychiatric patients, the stigma of mental illness, and the suicide, in North Korea. Results : In North Korea, psychiatric department was called as 49th(pronounced as Sahsip-gu-ho in Korean). Only patients with vivid psychotic symptoms came to psychiatric department. Non-psychotic depression or anxiety disorders usually were not dealt in psychiatry. The etiology of mental illness seemed to be confined to biological factors including genetic predisposition. Psychosocial or psychodynamic factors as etiology of mental illness appeared to be ignored. Psychiatry was apparently separated from political or ideological issues. The mainstay of psychiatric treatment is the inpatient admission and out-of-date therapy such as insulin coma therapy. Stigma over mental illness was common in North Korea. Suicide is considered as a betrayal to his/her nation, and has been reported to be very rare. Conclusion : The situation of psychiatry in North Korea is largely different from that of South Korea. Although some aspects of North Korean psychiatry are similar to psychiatry in former socialist countries, North Korean psychiatry is considered to have also its unique characteristics.

Regarding to Dandong as the gateway city of the Sino-North Korea trade, cultural anthropology characterizes it with a hybridity of four groups with a different combination of ethnic and national identity: Korean Chinese(Chosonjok), South Koreans, North Koreans and Chinese-North Koreans. And, microeconomics views the enterprises in Dandong area have different sizes and types in the Sino-North Korea cross-border trade depending on their owner's ethnic and national identity. However, these researches focuses mainly on the differences between the groups, falling short in showing how the group members utilize their double identities to maintain and prosper their businesses, coping with various and changing situations. This study introduces the concept of 'identity juggling' and applies it to Chosonjok cross-border traders. The results from the in-depth interview and survey indicate they juggles their Korean ethnic identity and Chinese national identity selectively in terms of their bilinguality of the Korean and Chinese, mobility crossing China, South Korea, and North Korea, and prospects on the trade revitalization thanks to potential mitigation of tensions in Korea peninsula.

This study is planned to discover the behavior of Korean peasants cope with the changes of structure last 30 years. So, I have surveyed the activists of Jindo Peasants Association through questionnaire. The outcome of survey are as follows; First, Peasants movement have been become weakened and the hope of future have disappeared. Although they have resisted the pressure of structural changes zealously, their life conditions have worsened. So, Peasants movement have been become weakened and they have no alternative choice. Second, The economic situations of all activist those who surveyed have worsened and there is no exits. If looking only at the surface of things, the socio-economic situations of Jindo peasants activists show a tendency to polarization. But, to tell the truth, overall immiseration have occurred at Jindo area. Third, confusion of their sense of values and weakening of self-esteem have occurred among the Jindo peasants activists. It is because that farming which is evaluated high in respect to cultural and industrial perspective, have been eliminated and disregarded. Especially, worsening of earnings and expenses make the peasants to be in the worse situations.

This paper explores students' question generation process and their study in small group discussion. The research is based on Anthropological Theory of the Didactic developed by Chevallard. He argues that the savior (knowledge) we are dealing with at school is based on a paradigm that we prevail over whether we 'learn' or 'study' socially. In other words, we haven't provided students with autonomous research and learning opportunities under 'the dominant paradigm of visiting works'. As an alternative, he suggests that we should move on to a new didactic paradigm for 'questioning the world a question', and proposes the Study and Research Courses (SRC) as its pedagogical structure. This study explores the SRC structure of small group activities in solving ill-structured problems. In order to explore the SRC structure generated in the small group discussion, one middle school teacher and 7 middle school students participated in this study. The students were divided into two groups with 4 students and 3 students. The teacher conducted the lesson with ill-structured problems provided by researchers. We collected students' presentation materials and classroom video records, and then analyzed based on SRC structure. As a result, we have identified that students were able to focus on the valuable information they needed to explore. We found that the nature of the questions generated by students focused on details more than the whole of the problem. In the SRC course, we also found pattern of a small group discussion. In other words, they generated questions relatively personally, but sought answer cooperatively. This study identified the possibility of SRC as a tool to provide a holistic learning mode of small group discussions in small class, which bring about future mathematics classrooms. This study is meaningful to investigate how students develop their own mathematical inquiry process through self-directed learning, learner-specific curriculum are emphasized and the paradigm shift is required.

Biochemical research was carried out on 4 human skeletal remains from historical lime-layered tombs assigned to the Joseon Dynasty in Oknam-ri, Seocheon. The preservation of femur was evaluated by stereoscopic microscopy and scanning electron microscopy. Most of specimens showed good histological preservation. The histological results proved to be a good potentiality for biochemical analysis using bio-molecules. The amelogenin gene and mitochondrial DNA (mtDNA) analyses revealed that three specimens perhaps have maternal consanguinity due to sharing with mtDNA haplogroup D4b1, and two specimens buried in the same tomb were a couple in Gatjaegol site. Carbon and nitrogen stable isotope analysis indicated that four deads diet were built around C3 plant as rice, barley, wheat and bean. In this study we characterized genetic and diet features from the social stratum who could make lime-layered tombs during period of the Joseon Dynasty. The results suggest that biochemical research using the human skeletal remains from the Joseon Dynasty has the great potential and reasonable value for archaeology, anthropology, and population genetics.

Most human bones of Joseon Dynasty period are so good condition that we can do research in physical anthropology, genetics and chemistry with them. In this study, we analyzed DNA typing using 6 human bones of Joseon dynasty period excavated at Janggi-dong, Gimpo. The DNA typing was mitochondrial DNA haplotype, Y-chromosome haplotype and sex determination. Prior to DNA analysis, we distinguished histological index of 6 human bones. As the result of mitochondrial DNA analysis, most of bones were confirmed as haplogroup G, R11, M7, A5, etc. As the result of sex determination, 4 human bones were female and 2 human bones were male. The male haplogroup was confirmed as haplogroup O by the single nucleotide polymorphism analysis of Y chromosome. For extensive ancient human bone analysis, researchers need to apply a histological index to select ancient human bones and explain a relationship among ancient human bones with various analyses of mitochondrial and nuclear DNA.

We tested the hypothesis that an improved nutritional environment increases the size of stature sexual dimorphism (SSD) by comparing mean height changes in North and South Korean adults. For the first round of sampling, those North Korean refugees who had reached the age of 20 years before leaving North Korea were selected for the study. Then, two birth-year cohorts born between 1955 and 1959 and between 1980 and 1984 were finally selected for the analysis (383 males and 529 females). North Korean refugee mean height data were compared to the mean height of the comparable South Korean population derived from 2004 Korean size results (373 males and 429 females). The results of the analysis showed that there was no increase in mean height among the refugees, either in males or females, between the two birth-year cohorts. As a result, no change in SSD was observed between the two birth-year cohorts. In contrast, South Koreans showed a remarkable increase in height, with males having a greater increase during the corresponding 25 years. Consequently, South Korean SSD increased significantly with time. These results support the hypothesis that improved nutritional quality increases SSD.

The present article reviews recent arguments on the moral-conventional distinction in moral judgment and discusses the implications for moral psychology research. Traditional research on moral judgment has considered both the evaluation of transgressive actions of others and the categorization of the norms on the moral-conventional dimension. Kohlberg, Piaget, and Turiel (1983) regard moral principles to be clearly distinguished from social-conventional norms and suggested criteria for the moral-conventional distinction. They assume that the moral domain should be specifically related to the value of care and justice, and the judgment for the moral transgression should be universal and objective. The cognitive developmental approach or social domain theory, which has been generally accepted by moral psychology researchers, is recently being challenged. In this article, we introduce three different approaches that criticize the assumptions for the moral-conventional distinction, namely, moral sentimentalism, moral parochialism, and moral pluralism. Moral sentimentalism emphasizes the role of emotion in moral judgment and suggests that moral and conventional norms can be continuously distributed on an affective-nonaffective dimension. Moral parochialism, based on the evidence from anthropology and cross-cultural psychology, asserts that norm transgression can be the object of moral judgment only when the action is relevant to the survival and reproduction of a group and the individuals within the group; judgment for moral transgression can be as relative as that for conventional transgression. Moral pluralism suggests multiple moral intuitions that vary with culture and individual, and questions the assumption of the social domain theory that morality is confined to care and justice. These new perspectives imply that the moral-conventional distinction may not properly tap into the nature of moral judgment and that further research is needed.
