The Royal United Services Institute(RUSI) was founded in the middle of the 19th century in Britain. It was developed through 'Naval Historical Revitalization Movement' in that time. Many celebrities and people who were interested in the Navy participated in the activities of the RUSI. For example, the forums and lectures were held by prestigious persons, like Sir Garnet Wolseley and the Duke of Cambridge. It also became the milestone for guiding the flow of the Royal Navy's thought with the Naval Intelligence Department and the Naval Records Society. The forum of the RUSI was the place for debating naval hot issues. The journal of the RUSI was the space for suggesting an idea and gathering public opinions for developing Britain's sea power. Therefore, the RUSI was the public sphere for the Royal Navy in the 19-20th Century. And especially, the paper prize contest of the RUSI was the culmination of the RUSI's activities for the Royal Navy. Naval prize essays gave messages to the Royal Navy about the changing situation of European naval powers. Also, they made many meaningful debates for the Royal Navy to overcome the difficult situations in that time. Those essays were reflecting the issues of the Royal Navy and leading the way for getting over it. Besides, some people appeared through the contest and they played important roles for making the contingency and planning the war. The contest reflected the past, anticipated the future, and selected the talented persons to shape the future. This developing aspects of the RUSI could apply to the Korea Institute for Maritime Strategy(KIMS). The KIMS already carries out the role of the RUSI very similarly. If the KIMS changes to the way for open-door policy to more people, it will work more efficiently for their goal. In this respect, the messages of the RUSI will be very useful for improving the activities of the KIMS.

The purpose of this research paper is to re-valuate the factors that affected the Royal Navy's rearmament and preparation for war by conducting analysis on the discussion held in the Britain on the strategic priorities and Navy's coping measures adopted during the interwar period. After the end of the WWI, each of the military arms of the Britain faced significant difficulty in securing budget and increasing their military power all throughout the interwar period, and the Navy was not an exception. The WWII that got started on September 1939 was the turning point in which this difficulty led to full-fledged crisis. Immensely many criticisms followed after the war and problems were identified when it comes to the Royal Navy's performance during the war. This type of effort to identify problem led to the attempt to analyze whether Royal Navy's preparation for war and rearmament policy during interwar period were adequate, and to identify the root causes of failure. Existing studies sought to find the root cause of failed rearmament from external factors such as the deterioration of the Britain itself or pressure from the Treasury Department to cut the budget for national defense, or sought to detect problems from the development of wrong strategies by the Navy. However, Royal Navy's failed preparation for the war during interwar period is not the result of one or two separate factors. Instead, it resulted due to the diverse factors and situations that the Britain was facing at the time, and due to intricate and complex interaction of these factors. Meanwhile, this research paper focused on the context characterized by 'strategic selection and setting up of priorities' among the various factors to conduct analysis on the Navy's rearmament by linking it with the discussion held at the time on setting up strategic priorities, and sought to demonstrate that the Navy Department's inadequate counter-measures developed during this process waned Royal Navy's position. After the end of WWI, each of the military arms continued to compete for the limited resources and budget all throughout the interwar period, and this type of competition amidst the situation in which the economic situation of Britain was still unstable, made prioritization when it comes to the allocation of resources and setting up of the priorities when it comes to the military power build-up, inevitable. Amidst this situation, the RAF was able to secure resources first and foremost, encouraged by the conviction of some politicians who were affected by the 'theory of aerial threat' and who believed that curtailing potential attack with the Air Force would be means to secure national security at comparatively lower cost. In response, Navy successfully defended the need for the existence of Navy despite the advancement of the aerial power, by emphasizing that the Britain's livelihood depends on trade and on the maintenance of maritime traffic. Despite this counter-measuring logic, however, Navy's role was still limited to the defense of overseas territory and to the fleet run-off instead of sea traffic route production when it comes to the specific power build-up plan, and did not understand the situation in which financial and economic factors gained greater importance when it comes to the setting up of strategic priorities. As a result, Navy's plan to build its powers was met with continual resistance of the Treasury Department, and lost the opportunity to re-gain the status of 'senior service' that it had enjoyed in the past during the competition for strategic prioritization. Given that the strategic and economic situation that Korea faces today is not very different from that of the Britain during the interwar period, our Navy too should leverage the lessons learned from the Royal Navy to make the effort to secure viable position when it comes to the setting of priorities in case of national defense strategy by presenting the basis on why maritime coping should be prioritized among the numerous other threats, and by developing the measures for securing the powers needed effectively amidst the limited resources.

Court ladies' tasks were largely divided into two. First, if there is a royal family event, such as the royal family's wedding or feast, they followed the rules and regulations of work division that was defined in "Gyeonggukdaejeon". Secondly, during normal days, they were divided into Jimil (至密), Chimbang (針房), Subang (繡房), Sesugan (洗手間), Saenggwabang (生果房), Naesojubang (內燒廚房), and Oesojubang (外燒廚房) and took charge of female work that was needed daily at the palace including serving, cooking, laundry, needlework, embroidery, cleaning, and nurturing. This organization was operated by different palaces such as the daejeon(king's palace), daebijeon(queen dowager's palace), junggungjeon(queen's palace), or sejagung(prince's palace). Court ladies were selected among female slaves of the government office or naesusa(a ministry of royal household properties). Although commoners were forbidden to be selected, they sometimes became court ladies voluntarily for financial reasons or because of the will of their parents. Court ladies had different appearances according to the division they belonged to. The court girls of Jimil, Chimbang, and Subang wore saeangmeori while court girls from other places had braided hairstyles. At Jimil, they wore all different kinds of chima(skirt) and jeogori(jacket). Usually, court ladies wore navy chima, jade jeogori, green gyeonmagi(top jacket) with the uyeomeori hairstyle. When working in the evening, they wore pink jeogori or yellow-green jeogori, navy chima with the jojimmeori hairstyle for easiness to stay up all night and work. Navy chima was worn by court ladies. If there was a royal family event upper court ladies wore uyeomi, black or green wonsam, and stewards wore garima and dangui.

The origin of mission command can be traced to the era of the Prussian military reforms led by General Gerhard von Scharnhorst after defeats in battle of Jena and Auerstadt in 1806 against Napoleon I. Mission Command is the conduct of military operations through decentralized execution based upon mission-type orders. Commanders issue mission-type orders focused on the purpose of the operation rather than details of how to perform assigned tasks. The mission command has become the command philosophy of the German military and recently many countries in the west accept it as a command philosophy. This study compare and analyze the Battle of St. Vincent and the Battle of Jutland to make sure if the army-initiated mission commands were also useful for the navy. From the late 18th century, represented by the era of Nelson, Royal navy changed from the inherited rigid command culture to guaranteeing the disciplined initiative of its subordinate commanders. In the Battle of St. Vincent in 1797, Nelson acted contrary to the commander's orders at the crucial moment, which gave Britain a decisive victory. On the contrary more than 100 years later, the command culture of the Royal navy changed into a centralized command culture. In the Battle of Jutland in 1916, Royal Navy couldn't win because the rigid command culture did not guarantee initiative of subordinate commanders and subordinate commander's passive attitude of waiting for the commander's instructions even at critical moments. Therefore, a mission command that guarantees the initiative of subordinate commanders is a useful concept even in the navy because it makes subordinate commanders to take full advantage of a sudden change in battle. Today's advanced information and communication technologies have raised questions about mission command. But even advanced technology can't completely eliminate the fundamental nature of the war-the fog of war. War is chaotic and unpredictable. In the flood of lots of informations, senior commander's judgement is not always right because he(she) is also human, he(she) can make mistakes. In the age of informatization, mission command is still effective because it involves increasing interaction and synergy between senior and subordinate commanders by ensuring their independence. Therefore ROK navy also needs to activate mission command. ROK navy must dismantle the zero-defect mentality and apply from educations as Prussian did to establish a mission command culture.

The purpose of this study was to identify and to classify the names of costume colors of women of Silla. The results of this study can be summarized as follows; Until now scholars and researchers interpreted nine colors in Sam Guk Sa Ki as nine colors explained in the dictionaries. However, term, nine colors in the contexts did not refer to the literary meaning of nine colors such as blue, red, yellow, white, black, green, purple, pink, and navy blue as explained in the dictionaries. 'Nine colors' of Silla were women's costume colors which were specified in the royal edict in the texts. Thus, 'nine colors' of Silla had a specific meaning rather than literary meaning. 'Nine colors' of Silla women's costume were identified as red( ), yellow(黃), purple(紫), purplish pink(紫粉), gold powder(金屑), pink(紅), yellow powder(黃屑), dark pink(緋) and dark purple(滅紫). These 'nine colors' were actually prohibited colors in women's costume in the royal edict. Women from true bone, the highest class, were prohibited the use of tow colors of red and yellow out of nine colors. While women from four du pum and common class were forbidden the use of nine colors out of total of nine colors. Kinds and numbers of colors of costume were used as a means of differentiating the social class and rank of women in Silla. Also it was found that women of Silla favored red purple, pink tones and yellow color in their costume and these colors were fashionable colors among women of Silla. These fashionable costume colors of Silla women seems to be influenced by fashions of women of T'ang dynasty of China. Red, purple, pink, yellow and green were favorite colors of women of T'ang dynasty of China.

Rolls-Royce is a global company producing advanced power systems for use on land, at sea and in the air. In order to develop competitive products and services, Rolls-Royce invests in technology, infrastructure and capability with much of the research carried out in a global network of University Technology Centres, such as the UTC in Thermal management at Pusan National University. Heat exchangers and thermal management play a critical role in today's gas turbine engines, maintaining the fuel and oil temperatures within the correct operational range. Future products are likely to place an increased duty on the thermal management system and thus require advances in heat exchanger design, installation and manufacturing. Heat exchangers further have the potential to play a vital role in Advanced Cycle Gas Turbine products. The Intercooled and recuperated WR21 marine gas turbine engine recently entered service with the Royal Navy and is delivering very attractive fuel burn in service. The development of an advanced cycle aero-engine is a significantly greater challenge, requiring better understanding of compact and light weight heat exchanger surfaces, novel installations and ducting systems and may required novel manufacturing techniques to achieve the volume, weight and cost necessary to realise a viable advanced cycle gas turbine aero-engine.

Purpose: This study aimed to investigate the potential factors that could affect the reduction rate of odontogenic cysts following decompression using cone-beam computed tomography (CBCT) for 3-dimensional volumetric analysis. Materials and Methods: The study sample consisted of CBCT images of 41 individuals who underwent decompression of odontogenic cysts at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Chulalongkorn University, between 2010 and 2022. Preoperative and postoperative CBCT results were collected, and a volumetric analysis was conducted to evaluate the differences in the reduction rate and the percentage of volume reduction of cystic lesions based on different parameters. Correlations between these parameters were analyzed to determine associations. Results: In this study, the average time of decompression for odontogenic cysts was 316 days. Males demonstrated a higher reduction rate than females (P<0.05). The reduction rate was directly proportional to initial cyst volume, with higher reduction rates for cysts with large initial volume than those with small initial volume (P<0.05). Spearman's rank correlation coefficient indicated a weak positive correlation between the initial cyst volume and the duration of decompression. Additionally, a strong positive correlation was observed between the initial volume and the reduction rate. Conclusion: Knowledge of the reduction rate of odontogenic cysts is vital for surgeons to evaluate the duration of decompression before enucleation and to determine a definitive treatment plan. Sex and initial lesion volume had significant effects on the reduction rate.
