이정재 조선대학교 2011 국내석사

In sports, victory or defeat is decided by the harmony between the physical and psychological (mental) abilities in individual athletes. Any player sometimes feels unadjusted to environment, which may lead to the problems, such as mistake, anxiety and lack in self-confidence. With the advent of the 21st century, human limitations, deemed to be insurmountable in the past, are overcome especially in record-breaking sports. However, such athletic performance is affected by several factors, of which a psychological one is important. As an individual sport, weightlifting has its performance greatly influenced by the factors of anxiety. After all, it is very important for players or their leaders how to control competitive anxiety. The present study aims at helping hyperanxious weightlifting athletes alleviate their anxiety and enhance their athletic performance efficiently by comparing the levels of state anxiety (cognitive anxiety, physical anxiety and state self-confidence) before a game using the Competitive State Anxiety Inverntoty-2 (CSAI-2) developed by Martens, Vealey & Burton (1990) to determine what influences the factors of anxiety have on record and outcome, analyzing what influences the levels of anxiety have on performance and applying the results to the field. Its population were the athletes who participated in the 49t National Male Junior Weightlifting Competition, the 22nd National Spring Female Weightlifting Competition and the 2nd National Female Junior Weightlifting Competition (simultaneously, a contest for the World Junior Weightlifting Competition) among the middle school and high school athletes registered at the Korea Weightlifting Federation. Of the population, 250 players were selected as subjects using the purposive sampling method. As per approval from directors at meetings before games, the objectives of this study were explained to the subjects, questionnaires were distributed among them, the self-administration method applied to answers and filled-out questionnaires were collected. The questionnaires were distributed among a total of 250 persons and filled-out ones were collected from 240 persons. A statistical analysis was made of the data collected from 232 persons, excluding 8 persons who answered the questionnaires insincerely or left some questions unanswered. The results are as follows: First, in terms of differences by gender in competitive state anxiety subfactors, the higher levels of anxiety were shown by female athletes than male ones in self-confidence, cognitive state anxiety, situational state anxiety and physical anxiety. Statistically, there were significant differences in self-confidence and cognitive state anxiety, while there was no difference in situational state anxiety and physical anxiety between male and female players. Second, in terms of differences by education level in competitive state anxiety subfactors, middle school students were similar to high school ones in self-confidence, while high school students showed the high levels of anxiety than middle school ones in cognitive state anxiety, situational state anxiety and physical anxiety. Statistically, there was no significant difference in self-confidence and cognitive state anxiety, while there were significant differences in state anxiety and physical anxiety. Third, in terms of differences by skill in competitive state anxiety subfactors, the higher levels of anxiety were shown by the students who won no prize at national competitions than those who won prizes at the same competitions, in self-confidence and physical anxiety, and by the latter than the former in cognitive state anxiety and situational state anxiety. Statistically, there were significant differences in self-confidence alone. Forth, in terms of differences by athletic career in competitive state anxiety subfactors, the higher levels of anxiety were shown by the students with the athletic career less than 3 years than those with other athletic ones, in self-confidence, and by the students with the athletic career of 3 to 5 years than by those with other athletic ones in cognitive state anxiety, situational state anxiety and physical anxiety. Statistically, there were significant differences in self-confidence alone. As a result of post-analysis, there were significant differences between the students with the athletic career less than 3 years and of 6 years or more. Fifth, in terms of differences by weight in competitive state anxiety subfactors, the higher levels of anxiety were shown by lightweight and heavyweight students than other weight ones in self-confidence, and by heavyweight students than other weight ones in cognitive state anxiety, situational state anxiety and physical anxiety. Statistically, there was no significant difference in self-confidence, cognitive state anxiety, situational state anxiety and physical anxiety. Sixth, in terms of differences by weight reduction in competitive state anxiety subfactors, the higher levels of anxiety were shown by the students without weight reduction than by those with weight reduction in self-confidence and by the latter than the former in cognitive state anxiety, situational state anxiety and physical anxiety. Statistically, there was no significant difference between the both groups.

R.Schumann의 Davidsbundlertanze Op.6.에 대한 분석 연구

이정재 전주대학교 1998 국내석사

The analyses of Davidsbundlertanze op.6, a Schumann's piano work, can be summarized as follows : First, all of the pieces in Davidsbundlertanze op.6, have an characteristic feature by the character piece of imaginary characters, In this piano work, Floerstan is a passionate and subjective character, and Eusebius is a speculative and objective one. These two imaginary characters show a strong antagonism in character each other. Second, from a viewpoint of tonality, Davidsbundlertanze op.6 consits of nine major key pieces and nine minor key pieces. We can find that the b minor has been mainly used for many pieces(No.2, 4, 11, 12, 13) and some pieces are different from others in cadence of the tonality has beeen used generally for the modulation throughout all pieces. Third, with regard to the harmony, there are some pieces that the I chord has not been used at the beginning of them, and also the nonharmonic tones have been used many times. In addition, the 7th chord and the altered chord are discovered very often in many pieces. Fourth, relating to the time, Schumann used the series of double time like 2/4 time or 6/8 time using the 3/4 time throughout all pieces. That is, he used the mixed times very often. Fifth, for the melodies, Schumann used many times the conjunctive progression and the contrary motion in this work, and these two melodies show effectively an antagonism in character between two imagniary characters. In the Florestan-characteristic pieces, Staccato and the disjunctive progression of the wide range harmony have been mainly used under the dynamic of Forte and also Stimmtausch has been used many times. They mainly express an excited and enthusiastic atmosphere. And they are also very impulsive and violent under the rapid tempo, showing an unexpected contrast of Dynamic. In case of the Eusebius-characteristic pieces, the single harmony of Arpegio and the conjunctive progression appear in the Dynamic of Piano. Sixth, referring to the rhythm, as it is expressed well in Schumann's othe piano works, Syncopation, Sforzando that appears very often in the weak beats, the cross rhythms and the dots are found many times in this piano work. Considering the Schumann's character piece, it seems to be the same genre as the other composer's programme musics, however we can also find out that it has a lot of different aspects in content. Hence, we cannot easily regard his music as the one of the emotion aesthetics. As Schumann said that the poetic things are absolutely not of music only but a part of the aestetic things existed commonly in all kinds of arts, he was in a neutral position at all times even during the music era of Romanticism named "Strum und Drang" in German, and his unique thought, as summarized above, is very well expressed in an effect way through Davidsbundlertanze op.6.

강박적 사고의 긍정화를 위한 제품 디자인 연구

이정재 홍익대학교 국제디자인전문대학원 2021 국내석사

Nowadays, it is common for modern people to have obsessive thoughts not only in their company but also in their daily lives due to social needs, personal characteristics, and the influence of their surroundings. Such obsessive thinking may work positively in the short term to show results in higher individual performance, but in the long term, it can also have negative consequences such as feeling helpless due to Burnout and depression. In addition, obsessive thinking causes stress that is large and small, and in severe cases, it also has a bad effect on the body, such as musculoskeletal system, gastrointestinal relationship, and cardiovascular disease. Most modern people are aware of this fact, but they are often reluctant to directly solve problems through psychiatric treatment or counseling with counselors. This seems to be due to the lack of awareness of seriousness as mental and psychological problems are not immediately revealed, and the fact that such problems are often taken as words with a negative connotation of "mental illness." Instead, as part of efforts to overcome this, many people find ways to indirectly comfort themselves, such as traveling in their leisure time, make unnecessarily consumption, or doing various hobbies. However, so-called "healing" activities often require cost and time investment, which can lead to more fatigue. In this research, I try to study product design that can lead to obsessive thinking positively. The goal is to encourage users to have a positive psychological state with the product in their daily lives by using products that are comfortable and accessible around us. To that, various studies and trend research that could affect human psychology and cognition were conducted, and ideas on products that gave users a 'sense of accomplishment' were derived. When users operate the product through simple way, they can obtain immediate compensation for its behavior through sense of sight and smell. The product, which "so that users can achieve a sense of accomplishment through easy and simple actions," will permeate people's daily lives and play its role. The pace of technology development is too fast, and human life continues to improve. Nevertheless, people force themselves to keep up with the world and not to fall behind. The keyword "healing" is still valid even after decades of talking, and various trends with only slightly modified naming continue to emerge. I hope that the results of this research will contribute to the development of a more positive society. 오늘날 현대인들이 사회적 요구나 개인적 특성, 주변 환경의 영향 등으로 인하여 일 뿐만 아니라 일상생활에서도 강박적인 사고를 갖는 경우를 주변에서 흔히 볼 수 있다. 이러한 강박적인 사고는 단기적으로는 긍정적으로 작용하여 개인의 성과를 높이는 결과를 보여줄 수 있으나, 장기적으로는 번아웃(Burnout)으로 인한 무력감, 우울증 등의 부정적인 결과 또한 가져올 수 있다. 또한 강박적 사고는 크고 작은 스트레스를 유발하고, 심할 경우 근골격계나 위장관계, 심혈관계에 이상이 생기는 등 신체에도 좋지 못한 영향을 끼친다. 대부분의 현대인들이 이러한 사실을 인지하고 있지만 정신과 치료 또는 상담사와의 상담 등을 통한 직접적인 문제 해결은 꺼리는 경우가 많다. 이는 정신적, 심리적 문제가 당장 눈앞에 드러나지 않아 심각성에 대한 인식이 부족할 뿐더러, 흔히 이러한 문제를 ‘정신질환’이라는 부정적인 어감을 가진 단어로 받아들이기 때문인 것으로 보인다. 대신 많은 사람들이 이 극복을 위한 노력의 일환으로 여가 시간에 여행을 다니거나, 불필요한 소비를 하거나, 각종 다양한 취미 활동을 하는 등 간접적으로 마음에 위안을 얻을 수 있는 방법을 찾는다. 하지만 소위 말해 이러한 ‘힐링’ 활동들은 대부분 비용과 시간 투자가 필요해 일상과는 거리가 있거나, 오히려 이 때문에 더욱 피로도가 쌓이게도 한다. 본 연구에서는 심신에 많은 부정적인 영향을 줄 수 있는 강박적 사고를 긍정적인 방향으로 이끌 수 있는 제품 디자인을 연구하고자 한다. 우리가 주변에서 편하고 익숙하게 접할 수 있는 제품을 접근 방식으로 하여, 사용자가 일상에서 제품과 함께하며 긍정적인 심리 상태를 가질 수 있도록 유도하는 것이 목표이다. 이를 위해 인간의 심리 및 인지에 영향을 끼칠 수 있는 다양한 연구들과 트렌드 리서치를 진행하였고, 사용자에게 ‘성취감’을 부여하는 제품에 대한 아이디어를 도출할 수 있었다. 그 방법으로 사용자가 간단한 조작을 통해 제품을 작동시키면 제품이 시각과 후각을 자극할 수 있는 피드백을 주어 행동에 대한 즉각적인 보상을 얻도록 하는 ‘디퓨저(또는 발향장치)’를 제안하는 것이다. ‘쉽고 간단한 행동을 통해 사용자가 성취감을 얻을 수 있도록’하는 본 제품은 사람들의 일상에 스며들어 그 역할을 수행할 수 있을 것이다. 기술의 발전 속도는 너무나 빠르고, 인류의 삶은 계속해서 윤택해 지고 있다. 그럼에도 불구하고 사람들은 세상에 따라가기 위해, 낙오되지 않기 위해 자의로, 타의로 스스로를 강압한다. ‘힐링’이라는 키워드는 이미 이야기가 나온 지 십수년이 지났음에도 여전히 유효하고, 네이밍만 약간씩 변형 된 다양한 트렌드들이 계속해서 등장한다. 이러한 시대에서 본 연구를 통한 결과물이 보다 긍정적인 사회로의 발전에 조금이나마 기여할 수 있기를 희망한다.

이정재 홍익대학교 대학원 2010 국내석사

생명공학산업은 환경, 에너지, 질병, 고령화 등 인류의 난제를 극복하고 세계 경제를 선도할 핵심산업 분야로 급부상, 중요성이 크게 부각되고 있고 바이오기술(BT), 정보기술(IT)과 나노기술(NT)의 융합으로 생명공학 산업의 고도화에 더욱 핵심적인 역할을 하고 있다. 전세계적으로 향후 10년간 연평균 20% 내외의 성장률이 예상되는 대표적인 신기술 산업이다. 타 산업과 비교하여 바이오산업은 장기간의 연구개발 기간과 대규모 투자가 요구되는 등 개발 위험도는 높은 반면, 인류난제의 극복방안으로 중요한 핵심산업의 특성 때문에 매우 매력적인 산업으로 인식되고 있다. 따라서 선진국을 비롯, 세계 각국은 바이오산업 경쟁력 강화를 위해 총력을 기울이고 있다. 생명공학의 기술융합은 실험환경과 기기들의 변화에도 많은 영향을 준다. 실제 실험을 위해 사용하는 기기들이 컨버전스 되고 이것은 프로세스의 변화를 가져왔다. 하지만 실험기기들은 실험의 본연의 기능을 중시하여 실험환경과 장비와 장비간의 유기적 관계에서 사용자중심의 최적화된 경험을 주기 어렵다. 현미경은 생명공학 기술 발달의 기초가 되는, 유전자와 단백질 및 그 기능 등 기하급수적으로 증가하는 각종 생물정보의 데이터 처리 및 해석에 보다 효과적으로 다룰 수 있는 생명공학산업의 없어서는 안 되는 핵심적인 장비이다. 그 중요성에도 불구하고 실험연구 본연의 기능 만을 수행 하기 위해 기능에 더 중점을 두어 바이오산업의 실험장비 중에서도 사용자에 대한 디자인의 성숙도가 낮아 본연의 기능중심연구에 머물러 있고, 사용자 중심의 디자인 연구는 열악한 상황이다. 사용자 중심에서 환경과 사용운영에 대한 흐름을 이해하고 최적화하여 새로운 인터페이스 디자인이 필요하다. 21세기 화두인 생명공학 분야의 기술융합으로 변화하는 환경에서 현미경의 인터페이스가 어떻게 진화하였는지를 살펴보고 현재 시장 경향을 분석하였으며, 사용자를 이해하기 위해 현미경 사용자, 공간, 시간흐름, 제품이 상호 어떻게 연관되는지를 실증적인 조사, 분석 하여 문제점을 도출하고 사용자 중심의 인터페이스 디자인 요소를 제안하여 사용성을 높이고 실험프로세스를 개선할 수 있는 방향으로 전개하였다. 본 연구에서는 디스플레이와 무선통신의 디지털기술과 바이오 칩의 기술 융합으로 접안렌즈를 터치스크린으로 대체하여 정보분석과 결과에 대한 신뢰성을 높이고 시료글라스를 바이오 칩으로 대체하여 실험 프로세스를 단축하는 새로운 현미경 인터페이스의 형태로 진화되는 자원이 된다. 이러한 요소를 통해 연구된 사용자중심으로 디자인된 현미경은 향 후 세포가 자라는 것을 관찰하기 위해 하루에도 여러 번 반복되었던 실험프로세스가 통합 되고 사용자가 실험실 밖 어디에서도 실험을 할 수 있도록 사용자의 생활에 변화를 가져올 수 있기를 기대한다. Biotechnology has the ability to give humanity the tools to solve environmental, energy, and medical problems of an aging society. The fusion of fields, such as biotechnology with information technology and nanotechnology, highlights the importance of design convergence. In the next ten years, biotechnology is projected to experience a 20% rate of growth in the development of new technologies. Compared to other industries, biotechnology is viewed as risky because of the need for large, long-term investments. While high-risk, biotechnology investment endures because of the potential to solving the high-profile problems of humanity. The commitment of developed countries around the world to strength and competitiveness in biotechnology is evidence of the attractive nature of this high-risk, high-reward industry. The convergence of technologies has led to the subsequent convergence of devices in a laboratory environment. As devices are developed, they have become optimized toward improved function rather than toward the overall user experience. In a laboratory environment, an important challenge is providing a user-centered experience in the interaction between device and user. The microscope is a fundamental device in biochemistry and molecular biology, continuing to have an enduring role in the study of DNA, proteins, and cells. Its role will remain of key importance because of the ability to provide, process, and analyze data to the user. Despite the importance of the microscope to the researcher, the device remains function-centered rather than user-centered. In order to improve the overall user experience and usability, the laboratory environment and user’s workflow must be understood to optimize any new interface design. In the 21stcenturybiotechnology,markettrendsindicatetheconvergenceofresearchfieldsisdrivingtheevolutionofthemicroscopedesign. To improve the process of developing user-centered design and increase the overall usability of biomedical devices, study must be directed toward understanding a user’s space, time stream, workflow, and device interaction, In this study, the convergence of technological advances in display, wireless communication, and microchips demonstrate the evolution of a new user interface. The microscope described is designed to be user-centered for researchers that must grow cells and repeat tasks and processes several times per day. With the new ability for a user to work outside of the laboratory, this device offers the potential for a lifestyle change of the researcher.

도로교통 부문 온실가스 감축을 위한 지하철 이용활성화 인지도 조사

이정재 중앙대학교 산업창업경영대학원 2015 국내석사

기후변화에 대한 관심은 전 세계적일 뿐만 아니라 우리나라, 우리기업에게도 날로 증가하고 있다. 그로 인해 이 문제를 해결하기 위하여 국제사회는 기후변화 협약을 맺어 온실가스의 감축을 약속하였고, 우리나라 역시 BAU대비 30%를 감축하겠다고 발표하였다. 이에 따라 각 부문별 온실가스 감축 목표를 설정하였으며, 이 중 교통부문은 타 부문 최고치인 34.3%의 감축목표를 할당받았다. 교통부문의 경우 온실가스⋅에너지 목표관리제와 배출권 거래제를 통해 교통부문 온실가스 감축에 힘을 보태고 있지만, 목표관리업체의 대부분이 대중교통을 운행하는 업체라는 점과 전체 교통부문의 아주 일부분으로 제한된다는 데에서 문제점이 발생한다. 이에 따라 교통부문의 온실가스를 줄이기 위해서는 교통부문 온실가스의 대부분을 차지하고 있는 개인차량 이용자들을 제한하고 이들을 대중교통을 이용할 수 있게 정책적 홍보적으로 유도가 필요하다. 이에 본 연구는 이런 배경을 토대로 국민들의 기후변화에 대한 인식이 대중교통인 지하철 이용활성화와 도로교통 부문 온실가스 감축에 미치는 영향 및 지하철 이용활성화가 도로교통 부문 온실가스 감축에 미치는 영향을 알아보는데 그 의미와 목적을 가지고 있다. Interest in climate change is increasing worldwide as well as in our country and business. Therefore, international society negotiates the United Nations Framework Convention on Climate Change(UNFCCC) and agreed to reduce their greenhouse gases(GHG) to solve this problem. Also, Korean government announced that Korea will cut Greenhouse gas(GHG) by 30% from its business-as-usual(BAU) emissions. Accordingly, Korea set the GHG reduction target for each sector and traffic sector has been assigned a reduction target of 34.3% which is higher than other sectors. Although traffic sector reduces the GHG through GHG energy target management system and emission trading, the problem is that most of management firms are managing public transportation and their effects are very limited in entire traffic sector. In order to reduce the GHG in traffic sector, we should limit the privately owned vehicle drivers, which occupies most of the traffic sector, by promoting publicity policy to use public transportation Based on national awareness in climate change, this study has meaning and purpose on how it effects public transportation utilization such as subway and reduction of GHG in road traffic sector.

Change in the alignment and distal junctional kyphosis development after posterior cervical spinal fusion surgery for cervical spondylotic myelopathy : 경추 척수증 척수병증에 대한 후방 경추 유합술 후 정렬 및 원위 접합부 후만 발달의 변화

이정재 가톨릭관동대학교 일반대학원 2022 국내박사

This study analyzed the risk factors in patients who developed distal junctional kyphosis (DJK) after posterior cervical fusion. We retrospectively analyzed the clinical and radiographic outcomes of 64 patients, aged ≥ 18 years (51 and 13 male and female patients, respectively), who underwent single-staged multilevel (3-6 levels) posterior cervical fusion surgery due to multiple cervical spondylotic myelopathy. The surgeries were performed by a single spinal surgeon between January 2012 and December 2017. Demographic data, clinical outcomes, and radiological results were collected. We divided the patients into a DJK group and a non-DJK group according to the presence of DJK and investigated the risk factors by comparing the differences between the two groups. Of the 64 patients, 13 developed DJK. No significant differences in clinical results were observed between the two groups before and immediately after the surgery. At the final follow-up, a higher visual analog score for neck pain was observed in the DJK group compared to the non-DJK group (P < 0.01). The DJK group had a significantly lower T1 slope and a significantly higher C2-7 sagittal vertical axis (SVA) before surgery compared to the non-DJK group (P = 0.03, P < 0.01, respectively). Immediately after surgery, the difference between the two groups decreased and no significant difference was observed. However, at the last follow-up, a significantly higher C2-7 SVA was observed in the DJK group (P < 0.01). At the last f/u, there is no discrepancy in T1S-CL. In multiple logistic regression analysis, preoperative higher C2-7 SVA and preoperative lower T1 slope were identified as independent risk factors (P = 0.03, P < 0.01, respectively). As a result, it was confirmed that DJK occurred along the process of returning to preoperative values. DJK can be considered to be caused by cervical misalignment due to excessive change in the surgical site in patients with low T1 slope and high C2-7 SVA before surgery. This also affects the clinical outcome after surgery. It is recommended to refrain from excessive segmental lordosis changes during multilevel cervical post fusion surgery, especially in patients with a small preoperative T1 slope and a large SVA value.

영화〈태풍〉의 ‘강세종’ 역할에 대한 연기 접근방법 연구 : 작품발표를 중심으로

이정재 동국대학교 문화예술대학원 2008 국내석사

This study set out to analyze the process of building a character named "Kang Se-jong" from The Typhoon details, to examine the patterns of practical application of screen acting theories on the field, and to discuss the limitations by consulting previous studies on screen acting and paying attention to "investigation into the methods to approach characters." Actors first try to understand the script and conduct preliminary analysis to create their roles effectively and build their characters. They specify their characters in a more three-dimensional manner by identifying the internal goals and external conditions of their characters. The Typhoon tells a story about the tragedy of a man who's consumed by revenge, love for the family, and ideology. There is a character called "Sin" who's a pirate dominating Southeast Asia and threatens the Korean Peninsular with a receiver kit for satellite induction with which to adjust the directions of nuclear missiles. The protagonist "Kang Se-jong" who's a lieutenant in the Korean Navy engages in conflicts and confrontations with Sin in order to stop his conspiracy. The movie illustrates how the world powers conspire and betray against each other over Northeast Asia and depicts the tragedies of the two Korean men and the meanings of individuals and the country. Based on the understanding of the story and characters, the investigator set the goal of "Kang Se-jong" as "stopping the attempt of "Sin" to revenge himself on Korea to protect it" as a Navy officer recruited as a national agent. I believe that it's essential for an actor to understand the process of delivering his intentions to the audience. He can make the delivery with no distortions and thus help to narrow the gap between the audience and him by understanding third elements between them and harmonizing them with his acting. In the practice of role creation, I divided the technological elements derived from the characteristics of a medium called film into filming, editing, and sound and combined them with acting to present a case of reinforced character building. The characteristics of film require an actor to come up with thorough calculations and strategies, and what's a key to them is the physical approach. Considering that film is a visually intensive medium, the approach seems to be effective and proper in that it allows an actor to secure his character's internal truth while observing many technological rules. An actor goes through very complex and diverse psychological conflicts on the lot. Although there were many methods suggested regarding the issue, they all failed to help them on the lot because the theories of acting or role creation were speculative and theoretical discussions that went on and on. The results of the study will hopefully be of more practical and specific help to the actors on the lot.
