In order to realize the new diplomatic development for the establishment of 'Asia Fate Community', Xi Jinping has adopted a "One Road, One Belt" policy. Based on five core philosophies, One Road, One Belt with neighboring countries has been established to full-sided cooperation and mutual benefit relations. In this paper, I would like to suggest some suggestions on how to use China's One Road, One Belt policy and Korea's Eurasian Initiative in Development strategy of tourism contents. First, The bridge role of Korean companies should lead to the development of tourism contents. Second, the promotion of tourism contents development for Chinese individual tourists should lead to another tourism contents. Third, we need to find ways to win joint orders with local companies in China so that they can lead to tourism contents. Fourth, seeking active use of workers and international students living in Korea. Fifth, the development of tourism contents based on cooperative relationship with North Korea.

In this study, the ventilation system of the enclosed conveyor belt for coal transportation was evaluated, and the particle removal efficiency according to the ventilation conditions was identified using computational fluid dynamics and particle behavior analysis. The most effective way to remove dust generated inside the closed conveyor belt is to adjust the position of the exhaust port of the duct so that the air is exhausted around the rear of the conveyor belt. And this method seems to work for another narrow and long spaces where air enters in one direction. In addition, when the air flow rate of the each duct was less than 300 CMM, it was efficient to increase the flow rate of the duct located at the rear of the conveyor belt, and when the flow rate of the each duct was higher than 300 CMM, it was efficient to increase the flow rate of the duct located at the front of the conveyor belt.

Purpose: This study aimed to measure static balance of low back pain patients while one-leg standing in abdominal compression belts. Methods: The study included 40 adult males and females at J university, divided into a low back pain patient group and a normal group through the Oswestry disability questionnaire (ODQ). The subjects were instructed to hold a one-leg standing posture for 15 seconds on a balance measurement plate while wearing an abdominal compression belt. Shifting distance (0.1 cm), mean velocity (cm/s), pressure, and contact area were analyzed using BioRescue (BioRescue, RMINGEIEIRIE, Rodez, France). The average value was used to measure the result 3 times for each condition. Results: Both normal and low back pain groups significantly decreased in the speed of sway while wearing the abdominal compression belt. Furthermore, the pressure of the center of motion significantly decreased in the low back pain groups while wearing abdominal compression belt. However, there were no significant differences in the speed of sway or the pressure of center of motion between groups after wearing the abdominal pressure belt. Conclusion: These results suggest that abdominal compression belts are one option for improving balance temporarily. However, balance after wearing abdominal compression vests depends on onset of back pain, age, and symptoms of pain in the groups with low back pain. Further research is needed to investigate muscle activity, dynamic balance, and the effect of the period of wearing abdominal compression belts in the variety of low back pain patients.

With the rapid development of global economic and trade, the ports in the North-east Asia region have developed greatly. In such a fierce competition, how to ascertain right evaluation methods to assess the competitiveness of the ports, and make scientific and rational development strategy for upgrading the overall level of competitiveness of ports in North-east Asia, has become the first task for all the ports for coping with the challenges. As China's sustained economic growth of more than 30 years, the economic power and comprehensive national strength has been changed, China's international status has been greatly improved. Also China has achieved remarkable new results in the construction of peripheral diplomacy, and further has consolidated the relationship of countries along the Silk Road Economic Belt. The strong position of RMB in foreign exchange market and the implementation of the strategy of "area" opening to the outside world accelerated economic belt along the silk road in China to the west open pace. On the basis of the SWOT analysis of the Lianyungang Port, combined with the comprehensive and practical port competitiveness evaluation indicators system and competitiveness evaluation method, calculate the competitiveness level of Lianyungang port in East China, and find out the problems must be solved. The development strategies for Lianyungang port under One Belt One Road were suggested.

Based on Fatal Accident Reporting System (FARS) data, safety belt effect- tiveness in preventing fatalities is investigated for the following five types of crashes: frontal, left, rear, right, and rollover. Passenger cars containing two occupants, a driver and a right front passenger, are included in this analysis. For each crash type, these cars containing the two occupants are classified into four categories according to the safety belt usage categories for the two front seat occupants, namely, both belted, both unbelted, and either one was belted but not both. Relative risks of driver and right front passenger fatalities are compared among these four cases. For each crash type, two independent estimates of safety belt effectiveness are obtained for drivers and for right front passengers. The weighted average of the two estimates is calculated for drivers and for right front passengers for the five crash types. Using FARS data starting 1978 throught 1983, safety belts are more effective in rollover accidents than in frontal collisions. In rollover accidents, safety belt effectiveness estimate for drivers is $68%{\pm} 6% $ and that for right front passengers is $71%{\pm}6% $ , in which the error limits indicate one standard error. Sfety belt effectiveness estimates for drivers and right front passengers involved in frontal collisions are $41%{\pm} 9% $ and $37%{\pm} 10% $ , respectively. For left and right sided collisions and for both drivers and right-front-passengers, none of the four estimates are significantly different from 0%, statistically : however, when left and right sided collisions are combined with far sided occupants(drivers involved in right sided collisions and right front passengers involved in left sided collisions) safety belt effectiveness is significant, $38%{\pm} 12% $ . For rear collisions, the estimate for drivers shows statistically significant positive effect, $60%{\pm}23% $ . while for right-front-passengers the estimate is not significantly different from 0%. These results show that a safety belt is an effective restraint system not only in frontal crashes but also in a variety of crashes.

China has achieved rapid economic growth in the late 1970s with economic reform and open-door policy. China's economic growth began initially in the eastern coastal areas and from the 2000s expanded to the western and northeastern regions where the economy was relatively underdeveloped. In particular, in 2013 'One-Belt One Road' initiative proposed by Xi Jinping, the current General Secretary of the Communist Party of China is not only a key strategy for China's advancement into the world and also provides important opportunities for the development of these backward regions. Inland Port is the inland logistics hub and plays a crucial role in enhancing access to maritime ports as well as access to adjacent inland countries. Therefore, a number of inland ports have been developed and operated in order to enter into overseas markets and secure resources in the northeastern and western regions of China. This study aims to examine the role and development of inland port in 'One-Belt One Road' scheme. In conclusion, 'One-Belt One Road' will further increase the role of inland port, and in response, the development of inland port will play a pivotal role in one belt one road initiative. In this respect, Korean companies need to consider plans to participate in the development and operation of inland ports in China, which would provide opportunities to spread Northern markets including China, Russia, Central Asia, Eastern Europe.

The ranking belts for Joseon dynasty officials that are based on references and relics are studied in this paper in terms of architecture, detailed names, and structural changes according to different time. Officials' uniforms consist of hats, clothes, belts, and shoes. Among these, the belt is an important sign that represents the wearer's ranking. The ranking belts of the Joseon dynasty which were brought from Ming at the late stage of the Koryo dynasty became classified as the following four classes : Seo-dai(a rhinoceros' horn, 犀帶), Gum-dai(gold, 金帶), Eun-dai(silver, 銀帶), and Heug-gag-dai(black horn, 黑角帶). A ranking belt consists of a basic belt body and a plaque that represents the wearer's rank. A plaque consists of 20 plates: three front-center plates that represent the Sam-tai(三台) constellation, six front-side plates that represent the Namduyug constellation(南斗六星), seven back plates that represent the Big Dipper(北斗七星), left side Bo(輔), right side Pil(弼), and a couple of Tamie at both ends. The architecture of the belt body; the basic frame for ranking belts, shows some differences between the former and the latter periods of the Joseon dynasty. In the former period, the belt had a pair of a buckle so that the wearers were able to adjust the belt size. But later, the belt didn't have the buckles to adjust the belt size and consequently it only performed a locking or unlocking function. Therefore, the belts in the latter period were longer than normal and one size fit all. In addition to the functional change of buckles, the shapes of the ranking belts show changes from the round shape to the square shape as time goes on.

A GDS (Geomagnetic Depth Sounding) method, one of extremely low-frequency EM methods, has been carried out to examine conductivity anomalies in and around the Korean Peninsula. In this study, new GDS data acquired at the five sites in south-eastern area of the peninsula were incorporated into the previous GDS data. In order to quantitatively interpret observed induction arrows, the 3-D MT modeling considering the surrounding seas of the Korean Peninsula has been performed to evaluate sea effect at each GDS site. The modeling results revealed that the observed real induction arrows were not explained by solely sea effects, consequently two conductive structures that are responsible for the discrepancies between observed and calculated induction arrows were proposed. The first one is the Imjingang Belt, which is thought as an extension of Quiling-Dabie-sulu continental collision belt. The effects of the Imjingang Belt clearly appear at the site YIN and ICHN. The second one is the HCL (Highly Conductive Layer), which is considered as a conductive anomaly by mantle upwelling produced in back-basin region. The effects of the HCL are seen at the site KZU, KMT101, and KMT 107 in the south-eastern region of the Korean Peninsula.

In ancient times, immigrants from Baekje wore various kinds of costumes that provided technological and aesthetic guidance for the Japanese costume, which has been modified and changed in Japan. The clothing and ornaments were strongly influenced directly by costumes of the Baekje period; therefore, many of the Japanese costumes at that time were crafted in the Baekje style. Through the antique records, paintings of tombs and bequests, we were able to find similarities between Baekje and Japan costumes in these categories: clothes, headgear, belt hooks and belt plaques, bronze shoes, and ornaments. (1) Clothes : They wore high-shaped hat and jacket and trousers(;袴) tied the bottom. (2) Headgear : There was a gilt bronze Conical Cap attached to the long tube with terminals in the shape of a hemisphere. (3) Belt hooks and belt plaques: There were horse-shaped belt hooks in mane styles and a checkered pattern on the lower part of the haunch and a belt Plaque shaped like the face of an animal. (4) Gilt bronze shoes: They were made with the style that had two side plates fixed in the instep side and heel-side. (5) Ornaments : They were made with flower-shaped plaques and spiral-shaped decorations. One earring was made with a three-winged pendent that were connected in a chain style and the others were in unique forms that were made by connecting narrow rings and a heart-shaped pendent.

This study analyzes the economic effects of reduction of green-belt. Green-belt is a kind of land which is restricted to be developed into housings. It is important for social welfare. It affects the social welfare by two routes. One way is through the housing market process. Development of green-belt into housings increases housing supplies and lowers rents. The other is that it improves the living condition by increasing green spaces. Therefore, the development of green-belt to housing can Improve or worsen the social welfare. This paper analyzes its welfare effects by simulations. The results of the paper show that reduction of green-belt increases housing supply and lowers the rent and asset prices. The social welfare is improved in the model.
