To investigate the air mass modification related with Yeongdong heavy snowfall events, we examined sensible and latent heat fluxes on the East Sea, the energy exchange between atmosphere and ocean in this study. Sensible and latent heats were calculated by a bulk aerodynamic method, in which NCEP/NCAR reanalysis data and NOAA/AVHRR weekly SST data with high resolution were used. Among winter precipitation events in the Yeongdong region, 19 heavy precipitation events (1995~2001) were selected and classified into three types (mountain, cold-coastal, and warm types). Mountain-type precipitation shows highly positive anomalies of sensible and latent heats over the southwestern part of the East Sea. When separating them into the two components due to variability of wind and temperature/specific humidity, it is shown that the wind components are dominant. Cold-coastal-type precipitation also shows strong positive anomalies of sensible and latent heats over the northern part and over the central-northern part of the East Sea, respectively. It is shown that the sensible heat anomalies are caused mostly by the decrease of surface air temperature. So it can be explained that cold-coastal-type precipitation is closely related with the air mass modification due to cold air advection over warm ocean surface. But in warm-type precipitation, negative anomalies are found in the sensible and latent heat distributions. From this result, it may be postulated that warm-type precipitation is affected by the internal process of the atmosphere rather than the atmosphere-ocean interaction.

The rainbow has been considered as a perfect representative of color harmony in nature. In this study rainbow's colors include seven spectral colors and changeable colors according to observational angle. This study performed a bibliographical inquiry into rainbow colors and the survey research for classification of rainbow color images in fashion design. First, a bibliographical inquiry includes the definition of rainbow colors, physical formation principles of the rainbow, and its aesthetical attributes and symbolism. Second, this survey classifies rainbow color images in fashion design. The results of this study are as follows: 1. The rainbow was the religious and symbolic object before 17th century, and after that period, the rainbow became an aesthetical object. The main symbolic meanings are similar in eastern and western culture: temporary bridge between two world, divine nature, hope/beauty/richness, war/ death/flood/drought. 2. This survey shows that 6 main factors of rainbow color images in fashion design are 'vigorous', 'colorful'. 'fairy', 'fresh', 'mysterious', 'brilliant'. Rainbow color image in fashion design shows past and futuristic image at the same time. The purpose of this study is to systematized the images theoretical bases which are applied to color expression and of rainbow colors and to find out the development about rainbow theme by designers.

무장한 남자(L'Homme armé) 선율에 대한 고찰

김지언 The Pianissimo 음악예술학회 2015 음악예술연구 Vol.5 No.1

The melody called L'Homme armé has long been used as the tenor of mass cycles between the 15th century and the end of the 17th century. However, a number of questions have been raised by scholars on both modern and historical aspects. This study examines the origin of the L'Homme armé chanson, the main question that still remains open. It may redefine the boundaries of the present knowledge about the origin. It also discusses the function of the prolatio notation to give a clue on its chronology. Therefore, it examines the possible significance of the text associated with Europe's political life in the latter half of the 15th century. Finally, it presents the compositional approach on the melody examined by other scholars. 본 논문은 15세기 후반부터 현대에 이르기 까지 수많은 미사곡과 현대 작곡가들의 작품에 사용된 선율인 <무장한 남자(L'Homme armè)>에 대한 연구를 목적으로 한다. 첫째로 <무장한 남자> 선율에 대한 근원을 살펴보는 문헌적 연구를 한다. 최초의 필사본, 작곡가와 작곡년도를 가늠했던 연구들을 살펴보아 음악사에서 아직도 미제로 남아있는 질문인 그 기원과 연대에 대한 연구 자료를 제시한다. 둘째로 당대를 풍미했던 작곡가들에 의해 경쟁적으로 선율이 모방된 이유를 알아보기 위해 <무장한 남자>의 가사가 가지는 상징적인 의미들에 대한 알아본다. 마지막으로 멜로디 자체가 가진 정선율로서의 가치를 설명한다. 본 연구가 갖는 학문적 공헌성은 <무장한 남자> 선율에 대하여 연구하여 당대 음악의 중요한 요소에 대한 좀 더 깊은 통찰력을 제시하고, 이에 대한 음악계의 후속 연구를 활성화하는 방향성을 제시하는 것이다.

유아의 음악성 측정준거에 관한 문헌고찰

김지언 The Pianissimo 음악예술학회 2016 음악예술연구 Vol.6 No.2

본 연구는 국내 유아음악교육분야의 연구에 나타나는 유아의 음악성 측정준거에 대해 분석하여 향후 유아의 음악성 연구를 위한 문헌적 기초자료를 제시하는데 목적이 있다. 이를 위하여 유아의 음악성에 대한 연구에서 측정된 다양한 변인에 관한 문헌 연구를 실시하였다. 유아의 음악성에 대해 연구된 변인들이 가지는 개념들과 각 변인의 구체적인 하위개념을 분석하고 측정된 변인간의 유사성과 차이점을 알아보기 위해서 최근 14년간 국내 학술지에 발표된 유아 음악성 연구 중에서 유아의 음악성을 연구변인으로 측정한 양적연구 45편을 검토하였다. 본 연구는 유아의 음악적 개념에 대한 이해 정도, 유아의 음악적 성향, 유아의 음악적 태도, 유아의 음악적 흥미, 유아의 음악적성, 유아의 음악지능, 유아의 음악적 능력, 유아의 음악 인지능력, 유아의 음악 표현능력으로 구분하여 분석하였다. 연구결과 유아의 음악성 측정준거는 음악적 요소를 구별해 내는 능력을 유아의 청각을 통해 측정하는 것과 유아가 음악을 듣고 즐기며 표현하는 내적·외적 정도를 검사한 것으로 크게 나누어지며, 각 음악성 측정의 하위 요소에 있어 개념에 대한 혼용이 야기되어 있음으로 이에 따른 표준화된 개념에 대한 정립이 요구됨을 발견하였다. The purpose of this study aims to research proper assessment tools of young children's musicality, so that researchers can use it as a useful fundamental material for their studies. For this, a literature study was executed on the studies of various variables of young children's musicality. Also, this study researched 45 quantitative studies on the variables of young children's musicality to verify the similarities and differences of the assessment tools' subordinate concepts. This analysis on the assessment tools was divided into nine different categories: the understanding of musical concepts, musical propensity, musical attitude, musical interest, musical aptitude, musical intelligence, musical capability, musical cognitive capability, and musical __EXPRESSION__ capability. The assessment tools were made up of auditory assessments for distinctive senses of musical elements and assessments for internal and external stages on musical attitude. However, since the subordinate concepts of musicality have been used together, a reorganization and unification of concepts for young children's musicality is needed through a literature review.

내측측두엽 간질환자에서의 측위증후

김지언 啓明大學校 醫科大學 1997 계명의대학술지 Vol.16 No.4

저자는 약물에 반응하지 않는 내측측두엽간질로 진단받고 간질수술을 시행받은후 1년이상 추적관찰하여 간질발적빈도가 술전에 비해 90%이상 감소되었거나 또는 완전히 소실된 환자 35명을 대상으로 180회의 간질발작의 징후를 CCTV를 통한 비디오로 분석하여 다음과 같은 결론을 얻었다. 1. 간질유발병소를 추정하는데 가장 도움이 되는 측위증후는 병변과 동측의 자동증과 함께 반대편의 이긴장성자세가 관찰되는 경우(87%)였으며, 그 다음이 병변위치와 반대편의 이긴장성 자세가 단독으로 나타나는 경우(75%), 병변과 동측의 자동증만 나타나는 경우(70%)였다. 2. 두부회전은 처음부터 병변의 반대측으로 회전하는 경우보다 처음에는 동측으로 회전하였다가 다시 반대편으로 회전하는 경우가 더욱 측방성의 가치가 높았다. Various signs of lateralization have been described in temporal lobe epilepsy (TLE). They include unilateral automatism, unilateral dystonic posture, versive head and body turning, ictal speech and so on. Because their specificity is still unclear, they are used to a limited degree in lateralizing the side of ictal onset. We evaluate the value of lateralizing signs in patients with TLE. We analyzed semiology of 180 seizures in 35 TLE patients who were evaluated for epilepsy surgery at Dongsan Epilepsy Center between November, 1992 and October, 1995. All patients had received epilepsy surgery, and they were seizure free or exhibited aura only for at least 12 months following surgical resection. Unilateral dystonic posture alone was observed in 22 seizures [ipsilateral : 6(25%), contralateral: 16(75%)]. Unilateral hand automatism alone was observed in 33 seizures [ipsilateral: 23(70%), contralateral: 10(30%)]. Unilateral dystonic posture accompanied by automatism of the other side was observed in 56 seizures [ipsilateral automatism combined with contralateral dystonic posture : 48(87%), contralateral automatism combined with ipsilateral dystonic posture: 7(13%)]. Versive head turning was noticed in 35 enents [ipsilateral 4(11%), contralateral: 22(63%), initial ipsilateral to contralateral : 9(26%), initial contralateral to ipsilateral: 0]. We conclude that the most valuable lateralizing sign in TLE is contralateral dystonic posture accompanied by ipsilateral automatism, and ipsilateral hand automatism alone and contralateral dystonic posture alone are also significant.

소모성 질환에 이환된 이유자돈에 대해 Porcine cytomegalovirus DNA Polymerase 유전자 검출과 분석

김지언,김지영,楚佳奇,채미경,장경수,김명철,박창식,전무형 충남대학교 수의과대학 동물의과학연구소 2004 動物醫科學硏究誌 Vol.12 No.-

Porcine cytomegalovirus (PCMV) causes piglet deaths, runting, inclusion body rhinitis, respiratory and reproductive disorders in swine herd, resulting in the significant economic losses in the swine industry. Recently, in the field of pig-to-human xenotransplantation, PCMV has been indicated as a potential xenogeneic pathogen with the risk for infection transmitted from the xenograft donor to the recipient. In this study, PCMV DNA polymerase gene was detected in the sera and nasal swabs from 30 heads of the weaned piglets affected with various wasting diseases and 10 heads of normal healthy piglets using polymerase chain reaction (PCR), and the diagnostic efficacy of PCR was evaluated. The prevalence of the PCR-positive by specimens from the diseased piglets were 83.3% in sera and 33.3% in nasal swabs. In the normal healthy group, the PCR-positive rates of sera and nasal swabs were 40% and 30%, respectively. Ten piglets (25.0%) out of 40 showed the simultaneously positive results in both of sera and nasal swabs. According to this result, it was found that the serum specimen was the most appropriate sample for detection of PCMV by PCR. The nucleotide sequence homology of DNA polymerase gene of PCMV KS1 as compared with the reference strain of PCMV (GenBank accesson no.AF027217) was 99.0%.

A Study on Bi-metal 3D printing Technology Development based on Laser Technology

김지언 한국산업융합학회 2020 한국산업융합학회 논문집 Vol.23 No.2

Additive manufacturing(AM) can create complex shapes directly in 3D CAD models with internal geometry compared to conventional subtraction manufacturing. AM technology has the advantage of adopting various materials as well as the reduction of material. However, the high cost of AM is still a significant barrier preventing the wider adoption of AM in industries. This paper analyzes the technical application cases for solving these entry barriers and proposes a bi-metal 3D printing technology as an anticipated application to overcome the difficulty. The paper investigates the complications for current 3D metal printing technology to conduct bi-metal 3D printing and addresses ongoing solution research based on laser technology.

마르그리트 뒤라스의 여성적 글쓰기 - 엘렌 식수의 사상을 바탕으로

김지언,이광진 중앙대학교 외국학연구소 2021 외국학연구 Vol.- No.58

This paper aims to analyze Marguerite Duras’ works based on Hélène Cixous’ theory. Hélène Cixous is a representative thinker who embodied the theory of ‘Feminine writing’, the core of French feminism in the 1970s. She insisted that women establish independent femininity away from femininity otherized and objectified by men. As examples of this study, we will present Marguerite Duras' Moderato Cantabile and L’Amant. Both works commonly show the ability of women to immerse and accept others, and to self-expand through this. Here we can see that women, by extension, humans, are not just fixed beings, but beings who can have diverse and variable egos. In conclusion, the primary purpose of feminine writing is to restore women's own subjectivity, but the ultimate purpose is to give voices and restore subjectivity to all minorities unilaterally defined and alienated by dominant ideology as well as women.
