  • 야구 타자의 능력을 측정하는 많은 세이버메트릭스 통계량들 중에서 WAR은 미국프로야구에서 가장 많이 사용하는 통계량이다. 그러나 한국프로야구 자료에는 수비에 관련된 변수에 포함된 야구장 요인, 포지션조정 그리고 리그 조정 통계량들이 존재하지 않으므로 WAR을 한국프로야구에 적용하는 데에는 문제가 있다. 본 연구에서는 타자의 능력을 측정하는 대안적인 세이버메트릭스 통계량을 제안하여 미국프로야구 뿐만 아니라 한국프로야구에서도 동시에 사용할 수 있도록 한다. 본 연구에서 제안한 타자력 지수 모형은 한국프로야구와 미국프로야구 타자들에 대한 다섯 종류의 통계량을 사용하여 개발한다. 우선 2015년도 최소 규정 타석을 만족한 미국프로야구 타자들의 자료를 바탕으로 타자력 지수 모형을 개발한다. 미국프로야구 타자들의 WAR과 비교하면서 본 연구에서 제안한 타자력 지수의 능력의 타당성을 검토한다. 다음으로 이 모형을 2015년도 한국프로야구 자료에 적용하여 한국형 타자력 지수를 제안한다. 한국프로야구 타자력 지수를 서로 다른 팀별, 나이별, 포지션별로 통계적으로 분석하고, 타자력 지수와 그들의 연봉과의 선형관계성을 토론한다. 연봉에 관한 회귀모형의 신뢰영역을 바탕으로 연봉책정의 적절함에 따라 46명의 타자를 세 그룹으로 할당하고, 세 그룹에 속한 연봉을 다양한 인자에 대하여 통계적으로 탐색한다.

  • 본 연구는 첨단과학 기술이 전투개념에 미치는 영향과 AICBM 기술을 접목한 미래 육군의 전투를 새롭게 개념화 하는데 목적이 있다. '전투개념'은 시대 상황에 따라 변화하고, 다음 두 가지 사례를 통해 볼 수 있다. 첫째, 적을 분석 하여 상대적 우위를 달성하는 개념이다. 이러한 대표적인 사례가 미군이 '공지합동전투'를 '다영역작전(Multi-Domain Operations)'으로 발전시킨 경우를 들 수 있다. 둘째, 전투개념의 변화를 이끄는 '과학기술'이다. 세계 1차 대전시 육상과 해상에서의 화력전이 항공기의 출현으로 인해 세계 2차 대전에서 '공중전'으로 발전된 것이 대표적 사례이다. 이와 관련하여 미군은 '미래사령부' 창설 등을 통해 첨단과학기술을 기반으로 미래 작전환경에 부합한 싸우는 개념과 미래 군 건설에 집중하고 있다. 따라서 우리 군도 4차 산업혁명의 주요기술을 기회로 활용하여 미래 전투개념을 발전시킬 필요가 있으며, 미래의 전쟁은 첨단과학기술이 전쟁을 수행하는 개념 발전에 영향을 크게 미칠 것이며, 이는 4차 산업혁명을 근간으로 한 AICBM 기술이 초연결·초지능·초융합의 형태로 국방운영에서의 혁신을 촉진할 것이기 때문이다. 따라서 본 연구는 첨단과학 기술이 전투개념에 미치는 영향과 AICBM 기술을 접목한 미래 육군의 전투개념을 제시할 것이다.

  • This study examined textiles used for ancient costumes of the $16{\cdot}17th$ century in Joseon period, focusing on fabric types and patterns of the costumes from tombs. The purpose of this study was focused on investigating the relationship between fabrics and social backgrounds, especially change in using fabrics through the war from Hidyoshi's Invasion of Korea in 1592. Since the war must have had an effect on the life of people's. The result of the study is that silk occupies $69{\%}$ of all textiles, and cotton, linen follow The weaving method of silk was primarily Plain and satin weaves. However the use of twill, gauze, and double weave, that had led weaving methods of silk during the Koryo Period, were considerably decreased in Joseon Period. Types excavated fabrics in the $16{\cdot}17th$ century Joseon period can be said various. Of this, silk was the most remarkable one till Hidyoshi's Invasion of Korea in 1592, when the ratio of patterned silk dramatically decreased. Contrarily, the ratio of cotton and plain fabric increased rapidly in Hidyoshi's Invasion of Korea in 1592. It is supposed that the result is largely due to unusual condition of the war time. After the war, it is estimated that use of pattened fabric as well as silk was decreased. Patterns of textile fabrics in $16{\cdot}17th$ century were various. In result of surveying a trend of increment and decrement, it is known that the ratio of patterned textile fabrics decreased dramatically in Hidyoshi's Invasion of Korea in 1592 and Manchu war of 1636. Tendency of textile use by social Position is more notable. It is appeared that a lot of silk fabrics were used in High hierarchy. The excavated remain and ratio of silk were the highest in Kyonggi Province including Seoul.

  • This study examined textiles used for the ancient costumes that are excavated from tombs of the Chosun dynasty, focusing especially on Po(overcoat). The result of the study is that silk occupies 79.8% of all the textiles used for Po, and cotton and linen follow. The weaving method of silk was primarily plain and satin weaves. However the use of twill, gauze, and double weave, that had led weaving methods of silk during the Koryo dynasty, are considerably decreased in Chosun dynasty. Danlyeong(단령) and Cheollik(첩리) had been made of various textile fabrics like cotton, linen, silk and blended fabric before Imjinwaeran(임진왜란). After the war, they were simplified in gauze weaved silk or satin weaved silk, And also patterned fabric were widely used for them than other Po. Simple fabrics like cotton, linen and plain weaved silk had been used for Aekjureum(액주름) and Jiklyeong(직령) before Imjinwaeran. After the war, Jiklyeong was used as underwears of Danlyeong, so it was made of high quality patterned silk. Dopo(도포) and Changuiryu(창의류) were mainly excavated from tombs after the war, high quality plain weaved silk are used than gorgeous Patterned silk. For the Dopho(답호) and Bansuui(반수의), before the war, they were made with various textiles such as plain weaved silk, twill weaved silk, satin weaved silk, cotton, linen, and blended fabric. But after the war plain weave was mainly used. In Jangui(장의), since it was mostly for women, many kinds of women's patterned silk were used in than any other Po. There were only a few excavation of Simui(심의) and most of them were made of ramie and were hemmed in black satin without pattern.

  • The purpose of this study was to identify the change and characteristics of 20th men's fashion. The result of the Study as follows; 1 In the period 1890's-World War I there was a display of opulence and extravagance Therefore men's fashion pursued with elegance and grace. The rise of sports and an erosion of rules of Victorian society were evident influences before 1914. So men's silhouette resembled athletic appearance and less formality was shown in masculine attire. 2. During the period World War I-1920's the new equality of social relations between the sexes had an influence in fashion. Unisex look evolved so boyish shaped became the feminine ideal, men wanted to boyish fitted leaner stylings and natural shoulder suits. In the twenties youth, who seemed to have a social dominance, asserted their own testes in fashion. New style of men's fashion such as oxford bags and Ivy League Look appeared. After World War I "comfort" is the aim of fashion so casualness was reflected in fashion: vests often were discarded and man wore a soft, detachable collars. 3. In the thirties depression marked a shift in mood from gaiety and progressivism of the twenties to the conservative, even reactionary values. The role of men and women returned to more traditional attitudes, Every men's general appearance was bold and manly: his chest was broad and well-built, his shoulders square and muscular. The effects of World War ll were not on style but on textiles and clothing construction: lighter weight fabrics appeared and construction was simplified 4. Men's dress changed only in detail and not in essence. But there was a continued increase in the variety of clothes and color in men's fashion.

  • Since the beginning of the second Sino-Japanese war in 1937, the entire Korean Peninsula has entered a full-fledged wartime system. Japan enacted laws that strongly regulate the distribution of various resources for war, and the same was implemented in Joseon. In particular, as iron, copper, lead, tin, and aluminum were mobilized as raw materials for military supplies such as weapons, private distribution decreased significantly, which had a great impact on the construction industry. As the use of metal such as steel as building materials requires permission from the provincial governor, it has become difficult to supply and demand except for some military facilities. In addition, the Japanese Ministry of Commerce and Industry encouraged research and development and manufacturing to promote the so-called "substitute goods industry" to make up for the shortage of supplies. Products with improved performance through chemical treatment by injecting only a small amount of the same raw material than before or using alternative raw materials have been developed. It was intended to overcome the limitations of lack of raw materials through the chemical industry. In terms of building materials, various substitutes were produced due to the incorporation of petrochemicals and the use of synthetic resins. This trend continued even after the end of the war and served as one of the backgrounds for R&D and production of new materials without returning to the "substitute goods."

  • Korea DM&S(Defence Modeling & Simulation) development plan includes construction of a distributed simulation model which enables us to construct, operate, integrate and connect war game simulations. US DoD and IEEE set the HLA/RTI as the standard of distributed simulation model. HLA/RTI models each simulator as a Federate and group of them as a Federation. Simulation with the model shows interoperability and finally executes a war game simulation. Because of different resolutions and features, it is not satisfied 'interoperability' and 'reusability' of simulation perfectly MRM (Multi Resolution Modeling) has been introduced, and many developed countries including the United States have studied the technology to simulate the model with different resolutions. This thesis proposes the need for introduction of MRM and analyzes both technical and operational validity when we apply MRM model to army war game simulations. For these purposes, we 1) find MRM main issues with the study about MRM basic concepts and case studies of MRM's applications, 2) present the need of MRM and its relation with DM&S development plan, and 3) analyze its technical and operational validity when we apply MRM to an example, CHANG-JO21 and JEON-TOO21.

  • Thermal decomposition of waste Achyranthes Root (WAR) emitted from its decoction process was investigated using a TG analyzer and a fixed-bed reactor. The WAR had the larger C and fixed carbon content than fresh AR (FAR) due to the extraction of hemicelluloses from FAR during decoction process. Thermogravimetric (TG) analysis results also revealed the elimination of hemicellulose by its decoction. Relatively high contents of the cellulose and lignin made high contents of their typical pyrolyzates, such as acids, ketones, furans, and phenols, in the pyrolysis of WAR using the fixed-bed reactor. The increase of pyrolysis temperature from 400 to $500^{\circ}C$ increased yields of oil and gas due to the more effective cracking efficiency of WAR at a higher temperature. The chemical composition of product oil was also changed by applying the higher pyrolysis temperature, which increased the selectivity to furans and phenols.

  • The purpose of this study is to understand the purchasing intentions of Chinese consumers to Huawei and other domestic brands in the context of the current Sino-US trade war. Taking the mass consumers as the research object, this paper designs Likert five-level scale to investigate consumers' purchase intention of domestic products in the future, and uses SPSS 23.0 and AMOS 23.0 statistical software to analyze and process statistical data. Using questionnaire survey and exploratory factor analysis, this paper constructs a model to analyze the impact of consumer ethnocentrism on consumers' purchase intention. By summarizing the overall purchasing intention of consumers, it is concluded that the development of domestic brands in the context of trade war is facing difficulties and challenges in the future, but at the same time, we must seize the opportunity of consumers' ethnocentrism under this background to positively influence their purchasing intention, make up for shortcomings, eliminate overcapacity, and seek greater development through technological innovation.

  • Purpose of the War history's study is getting instruction by analyzing victory and defeat factor. This study is studied by qualitative form in war study mainly. In case recording literature is full, victory and defeat factor analysis is easy, but occasionally definite analysis that recording literature is feeble is difficult. Also, when it is battle result that escape common sense, about victory and defeat factor, various estimations are brought. As such example, there is Myeong-Ryang sea-battle at Japanese Invasion of Korea in 1592 and Korea(Cho-Sun) naval forces did big victory in 13 vs. 133 numerical inferiorities. This study presented method of study that using agent based simulation model for quantitative analysis of these victory and defeat factor.
