The Chinese three northeastern three provinces - Heilongjiang, Liaoning, and Jilin - hold significant geographical, geopolitical, and commercial importance due to their location allowing for cross-border trade and transportation with North Korea. These provinces are crucial for establishing a complex Eurasian logistics network in line with South Korea's new northern policy. The Chinese three northeastern three provinces, as this region is known, boasts excellent maritime transportation links between South Korea, China, and North Korea, making it an logistics hub for transporting goods to Eurasia and Europe through multimodal transport. This study highlights the importance of securing a logistics hub area by fostering cooperation and friendly relations with China's three northeastern three provinces, which are crucial to the success of the New Northern Policy. In particular, the study aims to analyze current status of trade with these region and freight volume transported by ships and recommend political advice for securing logistics hub and revitalizing maritime transport. As the policy suggestion, this study is to establish a logistics hub by implementing joint port operations, constructing port infrastructure jointly, and operating shipping companies together. Additionally, we propose ways to revitalize the maritime passenger transport business between Korea and China, which involves expanding cultural exchanges and developing content.

In terms of seaborne contacts of Vietnamese court with foreign countries had two directions in the 19th century. One was with Island Southeast Asian ports such as Singapore, Malacca, Penang, Batavia, and Manila. The other direction was to Canton. The Canton contact of Vietnam again can be interpreted as one of the two directions of Vietnamese contact with China. The inland route far to Beijing was based on the political and diplomatic consideration, while the closer route to Canton by the court vessels was more for the economic consideration as the case for the contact with the Island Southeast Asia. In this article, author discusses three issues to illuminate the nature of the trips of the court vessels of the Nguyễn dynasty to Canton. First is to clarify detail itinerary of the trip from the Thuận An Estuary to the City of Canton via Đà Nãng and Hanan. Unlike to the Western ships that visited Canton but anchored at the Huang Fu, Vietnamese square-rigged/copper-bottomed ships sailed up the Pearl river to the Guangzhou city front to stay for four or five months before they returned to Vietnam. In the second chapter, various kinds of observation of the Vietnamese officials are discussed. If the objects of the observation are divided into two categories, one is the world Westerners in Canton, and the other is the world of Chinese. In a same place, Canton, the Vietnamese officials could have enough chance to compare the two worlds clearly. An important consequence for the Vietnamese officials was to conclude that the mechanical technology of the Westerners was better than that of Chinese. This kind of conclusion led the Vietnamese court to send court personnels to learn Western technologies and languages in the port cities of Island Southeast Asia and to enlarge contacts with them. In the last chapter, author tries to find out the items that the Vietnamese mission purchased in Canton in exchange to the Vietnamese products. The items that the Vietnamese mission purchased included ceramics, silk, books, and medicines. With the support of the Chinese settlers in Vietnam the mission was able to be involved in the deal of illegal items such as opium, and possibly some kinds of precious ginseng from Korea. Overall, the process of the itinerary, observation, and purchase during the trip to Canton was the way to form the new point of view of Vietnamese intellectuals towards China standing from the side of Westerners. To the Vietnamese who experienced both Canton/Macao and the Western worlds in the port cities of Island Southeast Asia China was not the only center of the world, nor the Westerners could be looked down as the barbarians. In Canton, a peripheral region looked from the imperial capital Beijing, but the most internationalized city of China at that time, Vietnamese officials were training themselves to overcome China.

I have researched in the field the religious and performance culture of Indonesia through the musical iconography of Borobudur. There are many kinds of musical instruments which belong to India or Indonesia, performers being either court or folk musicians. Contemporary south-east Asian Indonesia has a broad religious heritage. Most of the population is Muslim, but the culture and customs are rooted in Indian Ramayana. I discovered, for example, the same percussion instruments played on a person's knees. I also came across similar string instruments with long and elliptical resonance casks on the iconography of the Incense Burner and Byam temple stone pagoda of Beakje dynasty in Korea and in Borobudur in Indonesia. The two musical instruments can not be found in other countries, such as Silla, Koguryŏ, China or the silk road area, but only Indonesia or India. This suggests that Beakje Buddhism is from the southern regions rather than China. I also discovered the same dancing motion with the court performers on the iconography of Borobudur, and the same musical instrument and performance in the Gamelan in today's Indonesian performance. Despite a disjuncture between the people and their past, the Shailendra Buddhism is alive in people's life and culture in the present day. So we can discover some familiarities between Indonesia's Gamelan and the percussional performance in Korean Buddhist rituals.

Maize is one of the world's three largest crops and has a long cultivation history, and is an important crop used for various purposes such as food, feed, and industrial raw materials. Recently, the agricultural environment is changing, in which the limit of cultivation of crops is shifted to the north due to the rise in temperature due to climate change. This study was conducted in experimental field of Suwon in 2022 by setting a seeding period earlier than the sowing time to establish the North Korean agricultural climatic zone and meteorological conditions. The test cultivars were silage cultivars, Kwangpyeongok and Dacheongok. As a priming test method, it was used to directly plant seeds in the field through immersion using 4mM zinc (Zn) and 2.5mM manganese (Mn), which are trace elements for seeds. The planting season was early on March 15th, April 1st, and April 15th. The number of days from sowing to silk stage of the two cultivars sown on March 15, April 1, and April 15 was 107, 93, and 85 days for Kwangpyeongok and 109, 95, and 87 days for Dacheongok, respectively. The seed priming test did not show any difference from the control group in the growth survey up to the middle stage of growth. In another test, low-temperature recovery was confirmed through nitrogen (2-5%) foliar fertilization after 3 days, 5 days, and 7 days in refrigeration (0 degrees), a selective low temperature treatment for com in the third leaf stage. As a result of this study, it was confirmed that the low-temperature damaged com treated at 0℃ showed the same growth as that of the untreated com through nitrogen foliar fertilization. These results suggest that urea foliar fertilization for low-temperature damage reduction of corn for silage in high-latitude climates will be helpful. In addition, through the results of the study, additional studies are needed on the recovery mechanism and field application through urea foliar fertilization.

Kasugadaisha was built in the 9th century at Nara, Japan and it was the powerful Fujiwara's Shrine at that time. And also Wakamiyasai which has transmitted from generation to generation about for 1200 years at Kasugadaisha is typical sacrificial service of Nara Ages and it was built up with the historical background from Korean peninsula, especially Bekje. So it could be presumed to be important data to survey the sacrificial service in order to study on the ancient dietary culture of Korean and Japanese. 1) They used a live flower or paper flower in every sacrificial services. But in Korea, it has been used not only in the sacrificial services but also in happy events. And also it has been changed to use silk or developed rice cake instead of paper. 2) Steamed rice cake in Siru has been taken after boiled rice and unpolished rice. 3) Fried rice cake like doughnut was beginning of fried cake like Yak-kwa. 4) Four colors of red, yellow, green and white are symbolic at the high offering. There are a lot of cake, candy and some kind of biskuit four colors used in every events even now in Korea.

Tashkent Seoul Park was completed in June, 2014, following the signing of a sisterhood relationship between Seoul City and Tashkent, the capital of Uzbekistan in July, 2010. An open competition for the design of the park was held and, based on the design, the park was completed in June and open to the public in September, 2014. Tashkent Seoul Park is more than a public park in Tashkent. The focus was on making it a starting point for offering a new model for traditional parks of Korea built abroad. Korean gardens and parks built in overseas cities are not only a landscape space but also serve as an ambassador that promotes the culture of Korea to foreigners who are unfamiliar with Korean culture. Therefore, Tashkent Seoul Park was designed to reflect the beauty and uniqueness of Korean traditional landscaping to promote the image of Korea and Seoul. As such, the design and plan was focused on the best measures to make known Korean culture through a design that sets itself apart from the landscape of Uzbekistan. To date, Korean parks or Seoul parks that have been built overseas have focused on the re-enactment of gardens and parks during the Josun Dynasty era. But with the Tashkent Park, the process of the 170,000 people from Goryeo was also reflected onto the design so that the culture and sensibilities of old Goryeo could be felt as well. Korean traditional garden design elements for the representation of the Korean identity are taken from the pilot study. This design element includes not only that of Goryeo, but also the Josun Dynasty era to allow local people to experience a general Korean traditional garden. The traditional beauty and lyricism of Korea was presented to Central Asia through the park in Tashkent so that the citizens could feel the simple yet down-to-earth beauty of Korean aesthetics. As such, the spatial experience of story-telling in Seoul Park evolves from two points of view. First, it is a spatial experience from the perspective of the Goryeo period and of foreigners. It is a continuum of a landscape experience where one can trace the sentiments of Korea and a hometown in Korea by passing through lyrical and multi-faceted spatial structures. Second, it is an experience that evolves from the viewpoint of an outsider, including the Tashkent citizens. It allows visitors to read the various methods and attitudes in an unfamiliar landscape and terrain. Through a story-telling that is reminiscent of the Silk Road through which trade with East Asia took place, visitors can interact with Korean culture in the Korean Garden and throughout the process they can feel the very Korean sentiments. This park presents the latest example of a 'Korean Garden' formed overseas and thus presents a clue to understanding the representation pattern of the Korean aspects of Korean Gardens through a study on the design strategies.

Eri-silkworm is known as a tropical insect where as poly-voltine type in that area. It eats caster oil plant leaves which are cultivated as an every year cultivatable seed oil use in this country, even though it grows for many years in tropical countries. That is why, farmers have freedom for its cultivation in any year if they want. Therefore, eri-silkworm rearing service is flexible for its diet procurment as wish of farmer. The eri-cocoon price or economical fluctuation may be reactable for the rearing work not like as mulberry cocoon. Fortunately, it also eats cynthia tree leaves. Standing from such a easy condition, the authors have studied about this problem since 1963 to develope a culturing method of eri-silkworm rearing in this country and the authors brought out the matters to be produced as an industry scale. Here, the authors summarized their works of the results covering with thirty three work tables. The obtained results are as follows.

This study is to investigate effects of green tea and capsulated components mixture on body fat and serum lipid composition and fat distribution in college women students in terms of supplemented periods. During 3 months of this research, 34 college women students (average age 20.3 yr) were selected as subjects. Nutrient intake was investigated by questionnaire and 24-hr recall method. Anthropolatric assessments of the subjects were investigated by SBIA method (Segmental Bioimpedance Assay, Inbody 3.0). The results were as follows: mean body height was 162.5cm and mean body weight and mean BMI (Body Mass Index, kg/$m^2$) were 57.9kg and 21.9, respectively. Status of carbohydrate intake decreased significantly (p<0.05) and dietary fiber intake increased significantly (p<0.001) after supplementation. WHR (waist-hip ratio) decreased significantly (p<0.05) and body fat and percent body fat decreased significantly after supplementation (p<0.05). Total cholesterol and triglyceride decreased significantly after supplementation (p<0.001). Above results of this study show that green tea, silk peptide and dietary fiber supplementation-added routine diet improves body fat distribution, total cholesterol, triglyceride. Especially, declination of abdominal fat and WHR was notable, since that means diminution of risk factors for obesity and chronic degenerative diseases.

Background: It has been well documented that transient occlusion of the coronary artery causes myocardial ischemia and finally cell death when ischemia is sustained for more than 20 minutes. Extensive studies have revealed that ischemic myocardium cannot recover without reperfusion by adequate restoration of blood flow, however, reperfusion can cause long-lasting cardiac dysfunction and aggravation of structural damage. The author therefore attempted to examine the effect of postischemic reperfusion on myocardial ultrastructure and to determine the rationales for recanalization therapy to salvage ischemic myocardium. Materials and methods: Young Holstein-Friesian cows(130∼140 Kg body weight; n=40) of both sexes, maintained with nutritionally balanced diet and under constant conditions, were used. The left anterior descending coronary artery(LAD) was occluded by ligation with 4-0 silk snare for 20 minutes and recanalized by release of the ligation under continuous intravenous drip anesthesia with sodium pentobarbital(0.15 mg/Kg/min). Drill biopsies of the risk area (antero-lateral wall) were performed at just on reperfusion(5 minutes), 1-, 2-, 3-, 6-, 12-hours after recanalization, and at 1-hour assist(only with mechanical respiration and fluid replacement) after 12-hour recanalization. The materials were subdivided into subepicardial and subendocardial tissues. Tissue samples were examined with a transmission electron microscope (Philips EM 300) at the accelerating voltage of 60 KeV. Results: After a 20-minute ligation of the LAD, myocytes showed slight to moderate degree of ultrastructural changes including subsarcolemmal bleb formation, loss of nuclear matrix, clumping of chromatin and margination, mitochondrial destruction, and contracture of sarcomeres. However, microvascular structures were relatively well preserved. After 1-hour reperfusion, nuclear and mitochondrial matrices reappeared and intravascular plugging by polymorphonuclear leukocytes or platelets was observed. However, nucleoli and intramitochondrial granules reappeared within 3 hours of reperfusion and a large number of myocytes were recovered progressively within 6 hours of reperfusion. Recovery was apparent in the subepicardial myocytes and there were no distinct changes in the ultrastructure except narrowed lumen of the microvessels in the later period of reperfusion. Conclusions: It is likely that the ischemic myocardium could not be salvaged without adequate restoration of coronary flow and that the microvasculature is more resistant to reversible period of ischemia than subendocardium and subepicardium. Therefore, thrombolysis and/or angioplasty may be a rational method of therapy for coronarogenic myocardial ischemia. However, it may take a relatively longer period of time to recover from ischemic insult and reperfusion injury should be considered.

Large scale anoxic chamber system(volume $28m^3$) was developed and installed at The National Folk Museum of Korea for the first time in Korea. In order to get optimal anoxic treatment condition, we compared the disinfection of adults, larvae and eggs of cigarette beetles using nitrogen and argon. The time for complete disinfection of cigarette beetles in pine wooden blocks exposed to nitrogen at oxygen concentration 0.01% and 50% in relative humidity were 15 days at $20^{\circ}C$, 10 days at $25^{\circ}C$, and 7 days $30^{\circ}C$. Time were 10 days at $20^{\circ}C$, 7 days at $25^{\circ}C$, and 5 days $30^{\circ}C$ in argon anoxic atmosphere. From the mortality of cigarette beetles, optimal disinfection condition was oxygen concentration 0.01%, $25^{\circ}C$ in temperature, 50% in relative humidity and exposure time 21 days at nitrogen atmosphere. And when large scale anoxic chamber system was supplied nitrogen by nitrogen generator for anoxic treatment of many collections or large collections, it could be operated stably. To verify optimal disinfection condition, museum insects(adults, larvae, pupae and eggs of cigarette beetles in pine wooden blocks, cotton fabrics and Korean paper book, adults and larvae of drugstore beetles in pine wooden blocks, cotton fabrics and Korean paper book, larvae of varied carpet beetles in pine wooden block and silk fabrics, adults and larvae of hide beetles and adults of rice weevils in breeding boxes) which exposed at optimal disinfection condition, were completely killed.
