국가직무능력표준에 기반한 메이크업 교육과정 개발을 위한 프로토타입 설계 -전문대학을 중심으로-

홍세원 ( Sewon Hong ) 한국미용학회 2016 한국미용학회지 Vol.22 No.1

Makeup is the art of applying cosmetics to the human body such that it requires artistic skills and understanding of both human body and client management as well. Generally, makeup-related departments in most junior colleges have a two years`` course and it takes quite some time for learners to acquaint themselves with makeup skills. Therefore, to cultivate well-trained makeup artists in junior colleges, the makeup curriculum desperately needs a field-oriented down-to-earth approach. National Competency Standards or NCS is the nation-wide standardized educational system to cultivate well-trained work forces. Therefore, it is highly likely that a more realistic makeup curriculum will be set up if designed based on NCS. However, NCS specifies educational standards for each job ability but it does not mention some critical factors such as prerequisite learning elements, students`` learning ability and more detailed work field‘s needs. Therefore, before applying NCS to the curriculum, these factors have to be taken into consideration. Based on the research and analysis on these factors, this paper proposes a prototype for developing the NCS based makeup curriculum such that it emphasizes strengthening basic skills as makeup artists. This prototype consists of three phases as follows; Firstly, for an effective makeup education, key elements concerning color, client and human body are extracted and then taught as prerequisite. Secondly, some competency units appropriate at the junior college level are selected and then mastered exploiting those key elements. Thirdly, those key elements are evaluated through the field practice based on the performance criteria NCS provides.

국가직무표준에 기반한 취업현장 중심의 색채교육 연구

홍세원(SeWon Hong) 한국색채학회 2015 한국색채학회 논문집 Vol.29 No.1

색은 아름다움을 표현하는 핵심요소이며 인체의 미의 구현이 주요 교육목적인 미용관련 학과에서 색채교육은 매우 중요하다. 전문대학은 전문 미용인을 양성하는 주요 교육기관이며 전문대학의 미용관련 학과의 교육과정은 미용사 면허 취득을 위한 과목 중심으로 편성되어 있다. 또한 대부분의 전문대학 미용관련 학과는 메이크업, 헤어, 네일, 피부 등 세부전공으로 나누어지며 세부전공에 따라 색채관련 과목들의 배치는 상이하다. 이러한 상황 속에서 색채관련 과목을 강화해야 한다는 견해들이 연구를 통하여 제시되었으나 기존 연구는 색채관련 과목의 증강 또는 관련성 있는 과목의 내용 재구성 등 교육시간 강화에 초점이 맞추어져 있다. 그러나 전문대학의 교육목적이 현장에서 필요한 전문인 양성임을 고려한다면 색채교육의 강화를 논하기 이전에 색채교육이 세부전공에 관계없이 반드시 필요한 것인지 혹은 세부전공에 따라 차이를 두어야 하는지 또한 교육의 범위는 어디까지인지에 대하여 객관적 지침과 취업현장의 평가에 기반한 근거 확보가 선행되어야 한다. 그러므로 본 논문에서는 색채교육의 당위성과 교육범위를 다음과 같이 알아보고자 하였다. 이를 위해 먼저 색채관련 과목을 세부 주제별로 분류한 다음 각 주제의 교육내용이 세부전공별로 차이가 있는지를 검토하였다. 그리고 각 세부 교육주제와 국가직무표준(NCS)중 색채교육 관련 부분과의 비교ㆍ매칭을 통하여 색채교육의 세부주제별 현장 활용도를 알아보았다. 또한 미용관련 국가직무표준(NCS)의 색채교육에 대한 중요도를 현장 종사자들에게 평가하여 세부전공별 색채교육에 대한 견해 차이의 존재여부도 알아보았다. 조사결과 색채교육은 세부전공에 관계없이 공통적으로 필요하나 세부 교육주제에 따른 현장 활용도에는 전공에 따라 차이가 있는 것으로 나타났다. 그리고 일부 현장 종사자들은 다른 전공분야 현장에서 필요한 색채관련 수행업무에 대해 정확하게 인지하지 못하고 있는 것으로 나타났다. Color is one of the key elements in expressing beauty that it is very crucial to set up the optimized color-related courses in cosmetology education systems. Junior college ,so far, has been the leading educational institution in training beauty-related specialists and the curriculum of beauty-related departments in most junior colleges focuses mainly on subjects required to get the cosmetologist license. Moreover, generally, there are multiple sub-specialties in the cosmetology department such as makeup, hair design, skin care, nail art and etc that the importance of color-related subjects tends to depend on those sub-specialties. The existing research on optimizing color-related education has been focused mainly on adding either more color-related courses on the curriculum or color-related contents in the existing courses. Keeping in mind the fact that the main purpose of the junior college education system is to bring up the field-oriented specialists, the first thing to be done is to find a clear evidence about both the necessity and scope of color-related education as well as a distinction among sub-specialties in terms of learning level. Therefore, in this paper, both chromatology and personal-color, the two main color-related courses, are classified into a number of teaching subjects such that each teaching subject is checked if there is any difference at the training level among sub-specialties(makeup, hair cut, skin care and nail art). Furthermore, each teaching subject is then matched with the competency units among cosmetic-related NCS(National Competency Standard) to check the utilization of each teaching subject. These competency units are also surveyed and then prioritized by field workers; this is to figure out what is really required regarding color-related subjects in the real workplace. The result of the research shows that there is a consensus on the importance and need of color education irrespective of sub-specialties but some difference on the utilization of some color-related teaching subjects depending on the workplace. There is also a consensus on the need of color-related education irrespective of sub-specialties while some field workers are not known to be aware of the exact meaning of color-related job performance criteria.

스마트폰 기반 OAM의 QoS를 위한 Pull 메시지 방식 스케줄링 연구

김세원(Sewon Kim),김강석(Kangseok Kim),홍만표(Manpyo Hong) 한국정보과학회 2011 한국정보과학회 학술발표논문집 Vol.38 No.2D

본 논문에서는 기존 OAM(Operations Administration and Maintenance)시스템을 스마트폰 기반의 OAM 시스템으로 전환 시 발생할 수 있는 문제점을 고찰하고 이를 해결하기 위한 방안을 제안한다. OAM시스템은 네트워크 장비의 운용(Operation) 관리(Administration) 유지보수(Maintenance)의 기능을 통합하여 관리하는 네트워크 장비 관리 시스템으로 관리 장비에서 발생하는 대부분 메시지를 Push 방식으로 전달한다. 이를 스마트폰 환경에 그대로 적용 시 불필요한 메시지로 인한 과금 문제와 스마트폰의 성능 저하 문제를 초래할 수 있다. 해결 방안으로 Pull 방식 서비스를 이용하고 QoS 보장을 위해 중요한 메시지에 가중치를 두어 먼저 처리하는 우선순위 스케줄링 알고리즘을 제안한다.

손세원(Sewon Sohn),홍성희(Sunghee Hong) 한국자동차공학회 2003 한국자동차공학회 춘 추계 학술대회 논문집 Vol.- No.-

In order to investigate Bullet-proof characteristics of surface hardened Ti/Al alloy laminate structure under high velocity impact, a ballistic testing was conducted. Ballistic resistance of these materials was measured by protection ballistic limit(V_50), a statistic velocity with 50% probability penetration. Fracture behaviors and ballistic tolerance, described by penetratio modes, were respectfully observed, by V_50 test and Projectile Through Plates(PTP) test at velocities greater than V_50. PTP tests were conducted with 0˚obliquity at room temperature using 5.56㎜ ball projectile. V_50 tests with 0˚obliquity were also done with projectiles that were able to achieve near or complete penetration during PTP tests. Resistance to penetration, and penetration modes which face material was Titanium alloy, were compared to those which face material was anodized Aluminum alloy after cold-rolling.<br/>

Induced freezing tolerance and free amino acids perturbation of spinach by exogenous proline

Shin, Hyunsuk,Oh, Sewon,Kim, Daeil,Hong, Jeum Kyu,Yun, Jae Gil,Lee, Sang Woo,Son, Ki-Ho The Korean Society of Plant Biotechnology 2018 식물생명공학회지 Vol.45 No.4

The objective of this study was to investigate whether exogenous proline (Pro) could confer freezing tolerance of spinach and determine fluctuations of free amino acids in spinach leaf tissues under freeze-induced stress. Treatment with Pro (10 mM) resulted in more accumulation of Pro (~2.6-fold) in Pro-treated spinaches compared to untreated ones. These Pro-pretreated spinaches were more freezing-tolerant, showing more turgid leaves and petioles compared to untreated controls. However, when spinaches pre-treated with or without Pro were subjected to freezing, there was no significant difference in overall amino acid contents, emphasizing the role of Pro as an osmoprotectant. Freezing stress prompted intensification of total amino acid contents irrespective of pretreatment with Pro. Asp, Glu, Ala, and Val were the most abundant free amino acids due to increased protein degradation and nitrogen mobilization for plant survival under freezing stress. Arg, a precursor for the synthesis of polyamines in plants, was profoundly enhanced under freezing stress. This implies that Arg plays an important role in modulating freezing tolerance. Gly, Leu, and Ile were maintained at relatively low levels in all treatments. However, Ser, Tyr, and Lys as primary constituents of dehydrins were accumulated under freezing stress, suggesting that they might play a role in increasing cryoprotective activity under freezing stress.

Baekhee Lee,Giltae Yang,Sewon Hong,Duklyul Na,Heecheon You 대한인간공학회 2015 대한인간공학회 학술대회논문집 Vol.2015 No.10

Objective: The present study is to develop an algorithm for screening only swallowing movements out of various laryngopharyngeal movements using ultrasonic Doppler sensor and microphone. Background: Only swallowing movements need to be discriminated out of various laryngopharyngeal movements (e.g., vocalization, cough) measured by a swallowing measurement system using ultrasonic Doppler sensor for specialization in swallowing research. Method: laryngopharyngeal movement and audio signals during swallowing, cough, vocalization, respiratory, and neck movement were simultaneously measured three times to five healthy adults by ultrasonic Doppler sensor and microphone. A swallowing screening algorithm calculating movement-to-audio ratio applied with swallowing apnea was developed for screening only swallowing movements. Results: Vocalization, cough, and respiratory movements were perfectly discriminated with swallowing movements by the swallowing screening algorithm; however, neck rotation movements 73% due to occurring no laryngopharyngeal movements. Conclusion: The swallowing screening algorithm developed in the study could discriminate swallowing movements from vocalization, cough, and respiratory movements. Application: The swallowing screening algorithm can be applied to the swallowing measurement device and contribute to accurate evaluation of swallowing movements for patients with dysphagia.
