This paper seeks to enable the port of Shandong Peninsula to better handle the relationship between competition and cooperation and thus achieve common development. Based on an analysis of the current development of Shandong Peninsula ports, the paper proposes a port competition and cooperation strategy based on a Bertrand game. According to the game model, an income matrix of Qingdao Port and Rizhao Port, Yantai Port and Weihai Port is established and an analysis the income of each port under different strategic combinations is conducted to determine the strategy that is most conducive to the development of the ports. At the same time, we consider the instability of cooperation and establish a certain cooperation mechanism. Finally, an example is used to verify the effectiveness of the proposed port development strategy for Shandong Peninsula.

2천여 년 동안 한자를 사용한 베트남에는 지금까지도 한자의 영향이 닿지 않은 곳이 없다. 고대에 한자가 베트남의 다방면에 영향을 준 것은 부인할 수 없는 사실이다. 과거의 베트남은 한자를 ‘성현지자(聖賢之字)’, ‘재도지자(載道之字)’ 등으로 불렸고 그 위상이 매우 높아 문맹인 백성들은 한자가 적힌 폐지 한 조각을 보기만 하면 반드시 허리를 굽혀 줍는 등, ‘결석자지(敬惜 字紙, 문자가 적힌 종이를 귀하게 여기는 것)’의 문화가 존재했다. 반면, 지금의 베트남은 명승고 적, 절, 사원, 서적에 모두 한자가 적혀져 있지만 90%의 베트남인들은 자신의 조상들이 쓴 문자를 이해하지도 읽어내지도 한다. 베트남 학자들은 음수사원(飲水思源, 물을 마실 때는 그 근원을 생각하다. 즉 근본을 잊지 않다) 한 베트남 민족이 오늘에 이르러 ‘망본(忘本, 근본을 잃다)’하였음을 슬프지만 인정할 수밖에 없었다. 이로 인해 학자들은 서로 연합하여 베트남 정부에 한자의 재활성화를 요구했다.

For the whole process of circulation, distribution, application of the logistics system is a higher development step of transportation technology. Multimodal transport has linked all modes of transport together to serve the supply and consumption needs of the manufacturer. Currently, when e-commerce (EC) is on the rise, quality logistics and delivery services are the essential stages to achieve success in transactions. e-commerce today is no longer a fashion trend; it is an essential part of the retail industry. EC is changing the game of Logistics. The e-commerce world has been introducing many risks and complex issues that logistics and supply chain experts have never faced. E-commerce is the main impact on terminal logistics (last mile) and warehousing. However, it is also quite interesting to see how e-commerce is impacting airports and seaports. E-commerce is growing actively in Vietnam at a rate of about 25% per year, which is an excellent opportunity for business logistics services to get more orders. Moreover, the Vietnamese logistics market is small but has a high growth rate (20% - 25% / year). In recent times, this market is expected to change the face and grow faster due to the development of electronic retail in Vietnam and e-Logistics logistics trends in the world. However, to meet the requirements, to grasp the opportunities, logistics enterprises need to link to get a closed and synchronized service chain. So logistics companies need to increase information, respond faster, enhance technology to meet flexible processes, establish networks, and business links to meet changing needs. The article shows that the inadequacies and lack of cohesion between logistics service providers and e-commerce are limiting competitiveness, losing opportunities of enterprises, and the economy in the context of healthy industrial revolution 4.0. The assessment of the correlation and connectivity of logistics and e-commerce enterprises in Vietnam in the paper will contribute significantly to the development of Vietnam's economy in the period 2020-2025.

Vietnam is located in the centre of Asia - Pacific, on international maritime routes. With a long coastline of about 3260 km stretching from North to South, Vietnam has many favourable conditions to bring import and export goods to the world. Not only its production, but Vietnam is also an ideal place to conduct transhipment activities such as transit, border-gate transfer, and temporary import for re-export. Vietnam is a country with favourable natural conditions and geographical location to develop logistics services. Along with the process of opening and integration, the volume of goods produced, domestically circulated and exported and imported in recent years has grown strongly, which is the premise and driving force for the development of logistics services. Logistics is becoming an essential service industry of international trade activities and attracts extraordinary attention to the economic community. The role of science and technology in development has been widely accepted. In today's increasingly competitive international environment, technology is a vital strategic element for rapid socio-economic development. Thanks to technological innovation, businesses have many opportunities to improve productivity, product quality, as well as to improve the ability in designing new production lines, new products and improving the efficiency in business management and operation. In order to survive and develop sustainably, all countries have preferential policies to encourage businesses to innovate technology. Moreover, businesses also recognize the need for technological innovation to keep pace with the world's development trend; this is the experience gained from countries with developed economies. This paper presents some issues on trends and applications of information technology, blockchain technology in the field of supply chain management and logistics to improve the competitiveness and develop logistics services of Vietnam. On that basis, the article also proposes several recommendations to support businesses in innovation and technology application in managing and operating this critical economic sector.

딸기는 세계적으로 중요하고 인기있는 과채류이며 ‘설향’은 국내 시장에서 재배되고 있는 주요 품종 중 하나이다. 딸기의 생장과 화아 유도는 이 작물의 과실에 수량에 직접적으로 영향을 미치는 과정이다. 본 연구에서는 벤질아데닌(BA), 지베렐린 산(GA3), 살리실 산(SA)이 ‘설향’ 딸기의 생장과 화아 유도에 미치는 영향 을 조사하였다. 21구 트레이에서 번식된 지 3주가 경과한 런너묘를 온도는 25oC/15oC(주간/야간), 상대습도는 70%, 광원은 백색 LED, 광도는 300 μmol·m-2·s-1 PPFD로 유지되는 생장 챔버에서 재배하였다. BA, GA3 및 SA를 각 0(대조구), 100, 200 mg·L-1로 런너묘에 처리하였다. 이러한 생장조절제를 런너묘의 잎에 2주 간격으로 2회 엽면살포하였다. 9주 후의 생육을 비교한 결과, 생장조절제를 엽면살포한 모든 처리에서 대조구에 비해 근장과 엽록소함량(SPAD)이 감소하는 경향을 보였다. GA3 처리에서 엽록소함량(SPAD)이 가장 낮았다. 하지만 GA3 200 mg·L-1 처리에서 엽면적, 잎 생체중, 식물 생체중이 증가하였다. 화아유도율과 화수는 SA 200 mg·L-1 처리에서 각 85%와 식물체당 4.3개로 가장 높았고 그 다음으로 SA 200 mg·L-1 처리에서 높았다. 전체적으로 GA3 처리에서 식물 생장을 향상시켰고, SA 처리에서는 개화를 촉진하였다. 더 나아가 GA3와 SA를 혼합한 처리를 추가한 연구를 수행하여 생장조절제간의 관계를 구명하고 그 결과에서의 분자 메커니즘과 관련된 반응을 조사하는 것이 필요하다고 판단된다.

In this study, the principal objective was to investigate the effect of light quality and vessel ventilation on the growth and development, physiology, activities of antioxidant enzymes, and contents of mineral nutrients of carnation (Dianthus caryophyllus L.) ‘Marble Beauty’. Single node cuttings stuck into the plant growth regulator (PGR)-free MS medium in containers covered with caps with or without a ventilation filter were cultured first four weeks under white and then additional four weeks under either white (control), blue, red, or red + blue light emitting diodes (LEDs) for 56 days. Interestingly, a ventilated culture condition not only reduced the percentage of the hyperhydricity, but also increased the total chlorophyll content (Chl a + Chl b) of the plantlets as compared to the non-ventilated condition. In addition, blue LEDs produced plantlets with the greatest number of shoots and red LEDs produced plantlets with the greatest shoot length. The quality of plantlets was improved under a ventilation condition. Besides, under a ventilated condition, red + blue LEDs raised APX activity, and blue LEDs not only raised the activity of the CAT, but also increased tissue contents of such elements as K, Ca, Mg, Zn, Mn and Fe. The red LEDs increased contents of B and Si under a ventilated condition, and Na accumulation under a non-ventilated condition. Thus, including blue or red LEDs as the light source in a ventilated culture condition will produce plantlets of carnation ‘Marble Beauty’ in vitro with improved quality.

Physical smothering in a long time and toxic components due to the oil spill and oil slick disasters can not only affect directly, very seriously marine creatures, plants and life of other animals but also they pollute the air environment and reduce the health of human. Some activities such as the waterway accidents, the tanker or bilge discharges, and the acts of wanton vandalism are the main causes that pollute the ocean environment. The regulations of many countries such as the prevention of oil spill, reducing maximally the effects of the oil spill, and speeding up the oil spill degradation are to aim at treating and recovering fast, efficiently oil spills and oil slicks. The selection of suitable techniques for oil spill recovery and treatment depends on many factors such as the spilled oil volume, oil type, weather conditions (wind velocity), sea conditions (current velocity and wave height), cost and the fact situations of each country. In this paper, four methods used for oil spill recovery including physical-, chemical-, thermal-, and biodegradation method are introduced. The structure of mechanical devices including booms, skimmers and absorbent materials, the properties of chemicals such as dispersants and solidifies, the methods based on the thermal technologies, the major microorganisms for oil degradation for oil spill recovery, treatment and cleanup are analyzed. Each mentioned method also shows the advantages and disadvantages, as well as its applicability. The selection of suitable method for oil spill recovery purpose on the basis of the available equipment and techniques must be ensure that the collected oil spill volume is the largest, the period of time for recovery process is the shortest, aiming at minimizing the negative effects on the human, marine ecosystem, social economy.

This document gives a result of experiments on concrete using admixture Sikament® R4 combine with Sikacrete PP1. In developing countries, the development guides to build and set up a new infrastructure. In this case, the schedule of works is very important, which depends on the setting time of concrete structure. Specially, in tropical monsoon climate country, we need to use admixtures to increase the life time of constructions, especially concrete structures. Today, there are thousands of building, roads and bridges will be made. By using admixture, it not only helps to save the waiting time on the work site, but also increase quality of concrete structure. By using these good effects of admixtures, it’s necessary to find an optimal ratio of them in the mix design ingredient of concrete. The concrete strength can be controlled by changing a range of variety ratio of admixture in the mix design. This topic will find out the role of admixture and its relationship with the compressive strength of concrete.

Together with the development of this field, freight transportation industry becomes one of the most important service in the world as well as in Hai Phong. Meanwhile the number of company and quality of service increased due to the demanding of citizen, the price for this activities also raised.

Based on the reference achievement scholars before, combined with the actual survey results on Nom Tay documents currently stored in Institute of Sino-Nom Studies, conducted article comparing other cases face each other and are similar in structure between the written word: Nom of the Kinh and Tay ethnic group in Vietnam with the letter of the Zhuang ethnic blocks (Guangxi, China). This indicates that, basically 3 types of this writing there are a lot of similarities in terms of composition, the differences are very small and specific characteristics. This sector should be studied in depth and hopefully more will have interesting results in the future.

This paper unveils the strong competition in container cargo between Hong Kong Port which has been emerging as an international maritime center since the 1970s and Shenzhen Port which has recently gained remarkable achievements in the Pearl River Delta region. Among various competing strategies, the study focuses on the long-term one in which two ports will decide to compete by investing in capacity. The purpose of this research is to examine their decision, making process and to suggest future strategic actions in the current situation. Within its scope, only economic profit brought back from the investment is considered. For this reason, an uncertain payoff two-person game model is developed where an uncertain factor of demand is involved. In applying Uncertainty theory (Liu, 2013), the two methods to solve the game are introduced, including uncertain statistics and the expected Nash Equilibrium strategy. The results obtained from this research generate meaningful suggestions for future competition plan for the two selected ports, which conclude that Shenzhen is the dominant port in this long-term strategy. Compared to existing works on the same topic, the paper shows its distinctiveness by studying the latest competitive situation with regard to the uncertain demand in the game model.

Light scattering enhancement is widely used to enhance the optical absorption efficiency of dye-sensitized solar cells. In this work, we systematically analyzed the effects of spherical voids distributed as light-scattering centers in photoanode films made of an assembly of zinc oxide nanoparticles. Spherical voids in electrode films were formed using a sacrificial template of polystyrene (PS) spheres. The diameter and volume concentration of these spheres was varied to optimize the efficiency of dye-sensitized solar cells. The effects of film thickness on this efficiency was also examined. Electrochemical impedance spectroscopy was performed to study electron transport in the electrodes. The highest power conversion efficiency of 4.07 % was observed with 12μm film thickness. This relatively low optimum thickness of the electrode film is due to the enhanced light absorption caused by the light scattering centers of voids distributed in the film.

Seasonal characteristics of water and sediment qualities and potential effects of the freshwater discharge from a small tide embankment interior in a coastal area in Goheung county were investigated from May to September in 2012. Chemical oxygen demand values (COD) were mostly higher than 2 mg/L in summer ebb tide, which exceed the standard value of water quality criteria II of acceptable level for aquaculture activities. Nitrogen and phosphorus were found as the limiting nutrients for algae growth in summer and fall and in spring, respectively. Nitrogen was the limiting nutrient for diatom growth in the whole studied period. The sudden high values of COD, ammonia, dissolved inorganic nitrogen (DIN), dissolved inorganic phosphorus (DIP) were found in water sample collected from station 5 which located in front of the tide embankment sluice gate during spring ebb tide. The freshwater discharge form the tide embankment interior maybe affected the survey areas during a short time interval. Mean values of eutrophication index of the surveyed coastal region in spring, summer and fall were all bigger than 1. Water quality was mostly considered at level II which acceptable for aquaculture activities. Sediment quality in this study was generally in the range of standard for fisheries environment.
