Jade ornaments, which include slit earrings, scoop-shaped objects and tubular beads have been extensively identified in Northeast Asia, such as Korea, China, Japan and the Maritime Province of Siberia. Among them slit earrings are distributed in the whole area of Northeast Asia. Although this object shows the typological differences in accordance with the excavated region in detail, all of them are characterised by the slit on the centre of jade ring. The buried context and the shape of this object suggest that this artefact was the earring; thus it is named to 'slit earring'. Most of slit earrings of the Neolithic Age concentrate in Northeast China and the areas south of the Yangtze River, and the Japanese Archipelago. However, unfortunately, Slit earrings, which were produced in the tradition of the incipient and early phases of the Neolithic Age in Northeast Asia, have not been excavated in the Korean Peninsula. The number of slit earrings reported so far is eight, and especially until the 20th century, almost none was reported with its exact excavation location and only three of them are known as excavated through surface surveys and preliminary excavations. However, from the beginning of the 21st century onwards, the number of discovered slit earrings is increasing. Particularly, five pieces of this object uncovered in the 21st century are discovered in the official excavation; thus the exact archaeological context such as buried locations and chronologies could be estimated. By considering the buried context, slit earrings are associated with stone axes, which were produced in the incipient and early phase of the Neolithic Age in the Korean Peninsula. In addition, considering the number of unearthed objects is a few, it could be postulate that slit earring was the artefact that only a few persons, who had a special role in the society, could possess. However, slit jade earrings that have been excavated in the Korean Peninsula are extremely low in their number compared to the cases of its neighbouring countries such as China and Japan, and the researches on this subject have not been much conducted in Korea. Therefore, it is my supposition that slit earrings, which have been discovered in the Korean Peninsula, might be the imported item from the nearby areas. Particularly, the Southern Coast was closely connected with Japanese Islands and the Eastern Coast was interchanged with Northeast China or the Maritime Province of Siberia. Considering that excavations and researches on the Neolithic remains in the Korean Peninsula have not been sufficiently and actively conducted, it could be expected that the further investigations and researches will reveal the sufficient quantities of slit earrings in near future.

This study is presenting the logistics strategy in the international logistics markets which makes competition and corporation among north-east Asian countries to establishing the multi-pass Eurasian railroads. The countries located in north-east area of Eurasia like China, Japan, Russia and Korea are paying higher costs and disutility to the transportations and communications due to repeated conflicts and confrontations causes from the politic problems. They are being used surface transportation for most of all logistics between Europe and Asia except special merchandises because of characteristic of cargo to be air, the Silk Road remains vestige only which was main logistic passage to this area since BC. So far the Trans-Siberian Railway is being used by Russia mostly as north of Eurasian transport because of difficulties of service. The Trans-China Railway built in 1992 is not accomplishing as a international logistic passages. It is expected to take a long lead time because of characteristic of resource development and poor logistic infrastructure to the countries like Uzbekistan, double landlocked country, Mongolia and Azerbaijan, the countries do not be adjacent to the sea, even they have great economic jump-up plans through the development of their own resources. The Shanghai Cooperation Organization(SCO) start to sail officially in 2001 is constructed with China, Russia, Tadzhikistan, Kyrgyzstan, Kazakhstan and Uzbekistan as regular members of 6 countries and Mongolia, India, Pakistan, Afghanistan and Iran as observers 5 countries. It is started as a military alliance to protect terror, but now, it is expended to cooperate with the traffic, transportation, trade and share of energies. The Russia is doing their best to activate TSR as a government target to developnorth area equivalently, and economic develop of far-east Siberia. And also it is agreed provisionally to improve and repair of rail road between Nahjin and Hassan to connect TSR and TKR( Trans-Korea Railroad) by Russia, North Korea and South Korea with Russian's aggressive efforts. The development plan of this area is over lapped with GTI(Greater Tumen Initiative) promoted by UNDP, and is a cooperated project by 5 countries of South Korea, Mongolia, China, Russia and North Korea, subject to review the appropriation of energy, tour, environment, rail road connection between Mongolia and China and establishing a ferry route to north-east Asia. It is Japanese situation to pay attention to Russia and China even they have been supplying large-scope of infrastructure in Mongol area without any charges, target to get East Asia Main Rail Road to connect Mongolia and Zalubino of Russia. In case of the program for the Denuclearization of North Korea is not creeping, it will be accelerated to connect the TKR and TSR, TKR and TCR by somehow attending United States, including developing program promoted by UN ESCAP. As the result, Korean peninsular will continue the central role of competition and cooperation as in the past, now and future of north-east Asia, as of geographical-economics and geographical-politics whether it is requested or not wanted by neighbor countries.

Packaging of export cut lilies reduces physical damage during distribution like dropping, shock, vibration, compression and serves to protect from necrosis, microbial contamination and decomposition. Study on which packaging materials must be selected is necessary because it serves to direct effect maintaining quality and the degree of freshness. newspaper, perforated OPP film, Oriented Nylon film (ON), punched OPP film, OPP films are used in this study. Plant senescence of lilies was happened rapidly during storage at $25^{\circ}C$ rather than at $5^{\circ}C$. Also, water absorption, fresh weight at during storage $25^{\circ}C$ rather than at $5^{\circ}C$ In addition, fresh weight of lilies storage at $25^{\circ}C$ appears higher than at $5^{\circ}C$ all of the packaging materials except OPP because water absorption of lily storage at $5^{\circ}C$ appears higher than at $25^{\circ}C$, thereby suppressing the fresh weight reducing Also, effect on biological activity of lilies from shape of packaging material appears higher during storage at $5^{\circ}C$ than at $25^{\circ}C$. Compared with each packaging materials, newspaper packaging is the smallest effect on changes in biological activity of cut lilies during storage. Thus, the results demonstrate that flowering date are affected mainly by the storage temperature rather than packaging materials.

Because the import of Inonotus obliquus have been rapidly increased in Korea, we developed the Inonotus species-specific marker by using various sequences including ITS sequences, PCR-RFLP and STS primers and used this marker to determine both genetic relatedness and strains discrimination of Inonotus spp. Total 17 different Inonotus spp. were examined by using ITS sequences and classified into 2 different groups. One strain, ASI74008 isolated from Kamchaka island of Siberia, showed the high sequence identity (98%) at the nucleotide level to the other I. obliquus DSM strain, indicating the ASI74008 belong to I. obliquus species. Comparison of banding patterns after restriction enzyme digestions with PCR amplicons of ITS region revealed some variations depending on the species and strains. However, PCR products amplified with STS primer showed species specific patterns.Therefore, use of both STS primers and PCR-RFLP could help for better strain identification.

HCFC-22 (chlorodifluoromethane, $CHClF_2$), one of the major components in various refrigeration, is emitted mostly from developing countries, as its consumption is not limited until 2013 by the Montreal Protocol. In addition, HFC-23 (trifluoromethane, $CHF_3$), a by-product in the manufacture of HCFC-22, is also a powerful greenhouse gas. Here, we discuss the regional emission characteristics of these compounds based on high-frequency in-situ measurements using the "Medusa" GC-MS system. HCFC-22 and HFC-23 baseline concentrations measured at Gosan (Jeju Island, Korea) from November 2007 to December 2008 increased by 1.8 ppt/yr and 0.6 ppt/yr, respectively. Pollution events of these compounds were observed, very frequently (e.g., ~2~3 times) at Gosan than baseline levels. All the measurement data were divided into four groups by simultaneously considering the ratio (HFC-23/HCFC-22) and concentration (HCFC-22) at Trinidad Head (TH, California, USA). The residence time of trajectories were then analyzed in each of the four groups. The results exhibited the existence of a strong correlation with air mass origin for each group: 1) Air masses originating from Siberia in the north and from the Pacific in the south had ratios of 0.08~0.12 and concentrations of 196.9~254.3 ppt which is highly comparable to background air at TH. 2) Air masses passing over the Southern China exhibited similar ratios but higher HCFC-22 concentrations. 3) Air masses passing over the Northern China had ratios of 0.12~0.21. 4) Air masses passing over Korea and/or Japan had ratios of 0.01~0.08. Our results suggest that the HFC-23/HCFC-22 ratio can be used as a good indicator for the assessment of the pollution with Chinese origin. We also confirmed differences in air masses traveling over Northern and Southern China, most likely due to differences in air mass travelling speed over these regions before arriving at Gosan. This signature may be treated as one of the critical components in identifying the emission sources from different parts of China.

For the purpose of practical application of gamma irradiation for export lily without the ionic energy damage, 150 Gy gamma ray was suggested as the safe level on cut lilies, the oriental cultivar Siberia (white) and Sorbonne (pink). The combined treatments of 150 Gy gamma ray and sodium dichloroisocyanurate (NaDCC) at 0, 40, 100, and $200{\mu}g/l$, were tried to control lily leaf blight caused by Botrytis elliptica. Incidences of petal blight on the two oriental lilies at control were 93%-95%, whereas those at the combined treatments of 150 Gy and $100{\mu}g/l$ or higher of NaDCC were 76%-83%. However, severity of petal blight was not reduced by the combined treatments. Gamma irradiation at 150 Gy did not change the cut lily quality such as improve cut lily longevity of vase-life compare with the control. In addition, fresh weight, chlorophyll contents, and the color of pink petals of Sorbonne were not changed by 150 Gy of gamma irradiation. Therefore, we recommend the combined treatment of 150 Gy gamma irradiation and $100{\mu}g/l$ NaDCC for the standard operating procedure on cut lily for export quarantine to control leaf blight.

Western missionary nurses practiced in Korea from 1891. and the first trial to begin missionary public health nursing service in 1909 could not put into practice for short of nursing staff and budget. The main focus of missionary medical practice was not in public health program but in the management of missionary hospitals. A few of missionary western R.N. tried district nursing in 1910s. but their activities were personal and focused on the rescue of poor and sick patients. In 1917 the North American Methodist Church dispatched R.N. Elizabeth S. Roberts to begin district nursing in Korea. Roberts began maternal and child district nursing service. Her service was focused on teaching the method of bringing up children. bathing service, and home visiting for delivery. She could not but stop district-nursing service in 1918 to serve for a hospital in Siberia. The North American Methodist Church dispatched a few of R.N. to Korea in early 1920s and the missionary public health nursing of Korea could be activated. R.N. E. T. Rosenberger began public health nursing program in Seoul with Korean graduate nurse, Shin-gwang Han, and missionary M.D. Hall. Their public health nursing program was focused on maternal and childcare. They did home visiting in the morning, and served at a well baby clinic in the afternoon. The first baby competition began in 1925. and contributed to the teaching the method of bringing up children. They expanded public health nursing activity to school health nursing and milk station. Their public health nursing program was such a success that In 1929 Severance hospital. Eastgate Hospital. Taehwa Social Evangelistic center organized Seoul Child Health Union. Maren P. Bording, another missionary R.N. and midwife dispatched by the North American Methodist Church began public health nursing program at Kongjoo in 1924. Her program was focused on the maternal and childcare and close to that of Seoul. She started the first milk station in Korea in 1926. As she was a midwife and could get M. D. license in Korea, her program was more focused on maternal care than that of Seoul. The first day nursery school in Korea and the first graduate course for public health nursing in Korea began at Kongjoo in 1930. As the city of Choongcheongnam Province moved from Kongjoo to Daejeon in 1932, missionary public health nursing service in Kongjoo extended to Daejeon. There were lots of public health nursing program in Korea in 1920s and 1930s by missionary western nurses and Korean nurses. There were 13 missionary public health-nursing center in Korea in 1932. But in the late 1930s. Japan extended colonial war and drove out western missionaries. The missionary service in Korea was daunted. and the missionary public health nursing service could not but shrink.

Aircraft measurements have been executed for the purpose of monitoring the long range transported air pollution and estimation of air pollutant in/out-flux over the Yellow sea. Total 74 missions of measurements have been done since 1997, mainly in spring and fall. The main study domain was over $124^{\circ}$E $/sim$ $124^{\circ}$E, $35^{\circ}$N $/sim$ $37^{\circ}$N below 3,000m. In long-term trends, mixing ratios of $SO_{2}$N were around 2 ppbv expect in summer ( < 1 ppbv). NOx exhibited 24 ppbv and have no clear annual trends over the Yellow Sea. The concentrations of 03 were 51, 58, 41 ppbv in spring, summer and fall-winter, respectively. Backward trajectory was performed for three days to investigate the source regions of the air mass. Six regions were divided around Korea peninsular centering at $36^{\circ}$N, $126^{\circ}$E. I, II, III, IV and V regions represents in sequence northeast China and Siberia, Sandong peninsula and Balhae gulf, Sanghi and southern China, the south Pacific included Jeju island and the East sea included Japan. L region correspond to the airmass from Korea peninsula. Influx of $SO_{2}$N was approximately five times higher than outflux in yearly flux variation and showed a decreasing long-term trend since 1998. NOx outflux was average 0.095 ton/km/hr and three times higher than $SO_{2}$ outflux. In/out flux of 03 showed even distribution in yearly basis except 2002 (influx 5.45 ton/km/hr). The transported amounts from I, II, III regions were much higher than those from other region. In seasonal flux variation, influx levels of gas phases were the lowest in summer and the levels gradually increased from fall toward spring. As a result, transport of pollutants begins from fall and prevails in winter and spring.

For the study of the development of Asia map made by european map makers, one should consider Gog and Magog which existed in the maps for more than 700 years. Gog and Magog are described as an apocalyptic people in the Bible and medieval literature, and they are important elements in medieval mappaemundi and early modem world maps. This study classified representation types of Gog and Magog in old western maps. Maps were classed in to six categories according to the location and ethnic groups which they represent, and they were discussed in cartographic context. The maps until the fourteenth century place Gog and Magog, shut up by Alexander, near Caspian Sea. In the fifteenth century, Gog and Magog were described as Closed Jews in maps. From the sixteenth century they appear in the far northeastern part of Asia and they are named as Amagog or Ung and Mongul. In the mid-seventeenth century, they are located in Eastern Siberia by French cartographers. But with the expansion of geographic knowledge, Gog and Magog disappeared completely in the eighteenth century. In general, God and Magog were represented on the basis of traditional lore rather than on the Bible, and they became one means of mapping others of European community.

Balhae was an ancient Korean kingdom that existed almost 1,300 years ago. It was a dynamic time in the Korean history when the national strength was building up in terms of politics, economy and culture, thereby called as "Haedongseongguk, the powerhouse in the East". Balhae had dominated parts of Manchuria and the northern part of the Korean peninsula between the late 7th century and the 10th century, occupying the center stage of the northern Korean history. It serves as a window to the East Asia in the present as well as in the past. Yet, due to its geography spanning from the North Korea to Kilin Province of China to part of Heilongjiang Province and to the Littoral Province of Siberia, Balhae has been the center of historical disputes among neighboring countries that insist it is part of each of their own history. China argues that it was a prefecture of the Tang Dynasty, established by the Mohe, not a successor to Goguryeo, which is a China-oriented viewpoint of history. In addition, Russia recognizes Balhae as their first-ever medieval feudal state since the Littoral Province is now under their sovereignty. Therefore, the restoration of Balhae history is in line with the veritable establishment of the ancient Korean history. For this, it is necessary to embrace inter-disciplinary achievements and to continue efforts to adopt them rather than to blame the shortage of historical documents and the difficulty of the excavation of relics. If fashion is "a visual symbol" of our society, beauty culture serve as a mirror to reflect our civilization and culture directly or indirectly. Still, it is not easy to draw similarities by analyzing and comparing the attributes of various cultures and civilizations party because the essence of culture lies in diversity. Nevertheless, it is believed that cultural liaison as well as geographical liaison can be a medium to compensate for the limits of the foreign exchange history of Southeast Asia in proving the relationship between Goguryeo and Balhae, by examining and speculating beauty culture that reflect their period. It was confirmed by various documents regarding Goguryeo out of relics, historical sites and documents. Mural paintings showed how the people of Balhae wore and accessorized themselves. They also allowed us to speculate their way of living. As the contemporary historians can assert that Balhae is part of the Korean history thanks to the realism scholars in the late Joseon Dynasty, who rediscovered the Balhae history and conducted practical researches, it is expected that researchers who study beauty culture contribute to completing the restoration of the Balhae history by thoroughly examining our history, costume and beauty culture.
