A deletion of one out of the two copies of 9-bp repeat sequence (CCCCCTCTA), between the cytochrome oxidase II and Iysine tranfer RNA (COII/$tRNA^{Lys}$) genes in human mitochondrial DNA (mtDNA) has been used as a polymorphic anthropological marker for people of east Asian origin, and to lesser extent, Pacific and African populations. We searched for the 9-bp deletion of the intergenic COII/$tRNA^{Lys}$ Lys region in two Korean populations (175 from Seoul and 38 from Cheju) and examine the distibution of this deletion in world populations. The 9-bp deletion was detected directly by electrophoresis of the polymerase chain reaction (PCR)-amplified nucleotide(nt) 8211-8310 mtDNA fragment. The frequencies of the 9-bp deletion were significantly different between the Seoul (16%) and Cheju (8%) populations. Examination of data from the world populations suggests a geographic gradient. The frequency reaches its highest values in some Pacific island populations and decreases along the southeast Asia-Siberia transect. In spite of this geographic gradient, Mongoloid populations including Korean, Chinese, Japanese, and Mongolian populations were relatively homo-geneous with regard to the 9-bp deletion type of the intergenic COII/$tRNA^{Lys}$ region. These results indicate Koreans are genetically related to northeast Asian populations, and have a maternal mongoloid ancestry. Therefore, the 9-bp deletion of the intergenic COII/$tRNA^{Lys}$ region will provide significant information to elucidate the historical patterns of migration of the Mongoloids.

Most people have a desire to live longer. According to ancient Chinese and Korean mythology, Dongfang Shuo (Dongbang Sahk) lived for 18,000 years. According to a WHO report, the average longevity of humans has extended from 50-odd years in the 1960s to 75-85 years in 2016. Parabiosis, the joining to circulatory systems of two animals, was described as early as the 1860s. It provides a powerful experimental model to investigate the effects of one animal on its partner animal in vivo. Research on reverse aging is an immensely popular in parabiosis studies. In this review, the origin of the parabiosis model and important historical findings based on parabiosis models are presented. Surprising and debated discoveries in aging research are also introduced. Using heterochronic parabiosis of connecting circulatory systems of a young mouse and old mouse, various groups claim to have identified a reverse aging factor, growth differentiation factor 11 (GDF11), which was significantly reduced in blood of old mice. Although the potential existence of any one factor or factors that could reverse aging remains to be confirmed, studies have shown that the parabiosis model is powerful enough to detect reverse aging factors.

Busan was known firstly to the western world in the end of 18th century. When the Joseon opened a port under the western powers in the late 19th century, Busan was an important port. The increasing number of international ship exchange had magnified the harbor facility and the importance of lighthouses of Busan port. Busan maritime customs officer were in charge of installation and management of lighthouses. The operations of maritime customs became historical origin of Joseon changing from feudal society to modern nation. The majority of the documents from maritime customs was disappeared. So it was hard to know the exact history. But investigating documents and papers of Joseon, even media records will enable us to establish the objective fact relations. Moreover, published and translated data from the past make it possible such investigations. As a result, modern lighthouse of Busan harbor in the late Joseon after opening port was could be found. It could be offered to establishing the Korean modern history as the objective data.

By comparing the development history of rectangular coordinate system in Cartography and Mathematics, we assert in this manuscript that the rectangular coordinate system is not so much related to analytic geometry but comes from the space perceiving ability inherent in human beings. We arrived at this conclusion by the followings: First, although the Cartography have much influenced to various area of Mathematics such as trigonometry, logarithm, Geometry, Calculus, Statistics, and so on, which were developed or progressed around the advent of analytic geometry, the mathematical coordinate system itself had not been completely developed in using the origin or negative axis until 100 years and more had passed since Descartes' publication. Second, almost mathematicians who contributed to the invention of rectangular coordinate system had not focused their studying on rectangular coordinate system instead they used it freely on solving mathematical problem.

The purpose of this study is to survey various recips of the roasted skewered beef (Sanjuk) with twenty three classical cookbooks written before 1943 in Korea. The recipes of the roasted skewered beef are found thirty times in the records, which can be classified into six groups such as the palm-type skewered beef (Sulhamyukjuk), little finger-type skewered beef, mixed skewered beef, juice skewered beef, little finger-type skewered internal organs, and wide-cut skewered internal organs. The palm-type skewered beef and the mixed skewered beef most frequently appeared in the records. The 'Sulhamyukjuk' in the 17th century were inherited while changing its name to 'Sanjuk' in the late 18th century, which is the origin of 'Bulkoki'. There were two types of the roasted skewered beef, the palm-type and the little finger-type; and the palm type preceded the little finger-type. They were used with no change until the 19th century. Actually the roasted skewered beef existed even in the 16th century, but were put down in the early 17th century. In the cooking of 'Sulhamyukjuk' the process of dipping shortly into cold water in the midst of roast seems to absolutely disappeared. Some recipes of the roasted skewered beef were lost, but most have been inherited in the similar way with simplification including little use of internal organs. The main ingredients consisted of parts of cattle such as fresh meat, intestines, heart, liver, omasum, tripe, head, sweet bread, and lung with various vegetables and mushroom. And the main seasonings were mixtures of oil, soy sauce, sesame seed powder, scallion stalk, pepper, sesame seed oil, and salt. And sometimes wine, vinegar, ginger, garlic, and sugar were added.

This paper aims to analyse the historical-cultural sources of Azerbaijani national identity through the aspects of the Persian, the Turkish and the Russian influences, and to illuminate its complex characteristics. Then it will be examined the impact and consequences that the Azerbaijani identity exerted on its foreign policy. In the modern world, identities are formed and represented within a variety of shifting social, political, economic, cultural, and discursive contexts. Such understandings can have exclusionary consequences, particularly in pluralistic environments. Since its independence, the PFA government resorted to the arguments of ethnic origin and Azerbaijan's Turkishness to achieve its goals. Domestically, the failure of the ethnicity-based foreign policy was so great that even Azerbaijani Kurds, who under the Soviets had been virtually absorbed into the Azeri population, felt alienated and betrayed. Internationally, Azerbaijan turned Russia and Iran against itself and reduced bargaining power of Turkey since the latter grew increasingly concerned not to exacerbate its relations with Russia.

Recently, policies of metropolitan councils and primary local governments are diversely developing for the creation of child friendly cities. This study attempts to deal with implications that discussions on child friendly cities, which are recently becoming issues of local communities, have as a form of universal welfare on dimensions of child welfare along with discussions of the direction to which those implications can be applied. For this, this study was conducted largely in three parts. First, it observes the contents of the United Nations Convention on the Rights of the Child which is the spirit and basic foundation of child friendly cities and through this, it examines child welfare paradigms as a universal form of welfare and second, it observes the historical origin of child friendly cities that have modern significance along with the main characteristics of child friendly cities, and third, it explores methods with which to apply locality based community resource connections that currently exist to policies of child friendly cities.

Cosmetic functional ingredients are products of emotional convergence technology. Unlike pharmaceuticals, it is very important that cosmetics ingredients contain emotional attractiveness because they are household products that have limitations in their effectiveness. Ginseng has long been used as a major prescription of oriental medicine for human health. Detailed records such as the origin and propagation of ginseng can lead to various cosmetical application of ginseng as an emotional convergence ingredients that utilizes the authenticity and excellence of ginseng as an asset of K-beauty. In the unfortunate reality that the first records of ginseng use depend on ancient Chinese literature, it is very meaningful to describe and leave the records of ginseng used in the field of beauty. This study examined the general historical records needed for the study of the cosmetics application of ginseng and the recent findings of ginsenoside in the area of skin function, and provided basic data that can be applied to new cosmetics development research.

The purpose of this paper is to examine the process of Islamization in Java, focusing on religious discourse among Muslim intellectuals. How Islamic tradition and knowledge have been perceived and utilized and how they have interacted with those of non-Islamic origin will be discussed. For this, three Islam-related books written in different phases of Islamization are to be analyzed: Babad Tanah Jawi compiled by Mataram court in the 17th century, Serat Cabolek written by a court poet in the late 18th or early 19th century, and Fikih Anti-korupsi published by reformist and scriptural organization of Muhammadiyah in 2006. Babad portrays conversion to Islam as a process which does not demand a dramatic outward change in religious practice. Scriptural tradition of Islam and the dichotomy between what is Islamic and what is not were not mentioned in order to explain conversion. Spiritual and mystical enlightenment was emphasized heavily, and for this, the importance of non-Islamic traditions was fully acknowledged. Serat tells us that this period was characterized by the surge of scriptural and shariah-minded Islam, maintenance of non-Islamic traditions, clashes between scriptural Islam and old religious traditions, and Javanese efforts to harmonize these. In Fikih, non-Islamic tradition is replaced by scriptural Islam and disappears totally. Interpretations based on the Scriptures, however, do not monopolize it and are used together with mode of analysis from the West. It is too much to call this 'intellectual syncretism', in that Islamic Scriptures and Western knowledge do not mix but stand side by side. Three books under examination reveal that the process of Islamization in Java has not been uniform. It has been conditioned and shaped by local socio-cultural and historical circumstances, where active engagement and intellectual exercise of Javanese Muslims have played key roles. Even Islamization in the last few decades is not an exception. The surge of scripturalism and fundamentalism does not simply bring about a move to Arabization. Interacting with local intellectual and socio-cultural milieu, this has produced a sort of intellectual hybridity, which is unique to Muslim society of Java.

Objectives : Our goals were to examine how the well points in the fingers came to be and how their placements have changed, as well as to determine how they relate to the EX-UE11 points. Methods : We reviewed the classic textbooks to understand the origin and the changes of locations of the well points in the fingers. We also compared the location and indications between well points in the fingers and EX-UE11 points. Results : At first, the tips of the fingers, which are now thought to be the locations of EX-UE11 points, were once described as containing well points. Currently, well points are positioned 0.1 F cun distal-medial (or lateral) to the medial (or lateral) corner of the nail. In addition to the locational commonality, we found similarities between the well points in the fingers and the EX-UE11 points in terms of their indications; for example, bloodletting at these places is frequently utilized to treat emergencies, including acute stroke and fever. Conclusions : We suggest that it is highly likely that well points in the fingers and EX-UE11 points were initially the same acupuncture point and later classified into two different acupuncture points, given their identical locations and indications. If the clinical relevance between the change process of the well points' locations in the fingers and the EX-UE11 is studied in the historical literature, it is anticipated that the significance and clinical application of well points can be expanded.
