자동공정계획은 CAD 모델을 자동적으로 해석하여 CAM을 구동시키는 것을 목표로 하는데, 이를 위해서는 우선 CAD 모델로부터 특징형상을 인식하여야 한다. 특징형상 인식에 관한 연구는 근 20년간의 역사를 가지고 있지만, 그 연구 성과는 실용화되지 못하고 있다. 그 이유 중 하나는, 특징형상 인식과 자동공정계획 연구가 분리되어 진행되어왔기 때문이다. 본 연구에서는 인공지능 기법을 토대로 이 두 분야를 통합하여, 제조가능한 특징형상을 인식하고, 셋업을 최소화하며, 특징형상 간의 의존 관계를 설정하고, 최적의 가공 순서를 결정하였다. Computer Aided Process Planning (CAPP) plays a key role by linking CAD and CAM. Given CAD data of a part, CAPP has to recognize manufacturing features of the part. Despite the long history of research on feature recognition, its research results have rarely been transferred into industry. One of the reasons lies in the separation of feature recognition and process planning. This paper proposes to integrate the two activities through AI techniques, and presents efforts for manufacturable feature recognition, setup minimization, feature dependency construction, and generation of an optimal machining sequence.

Generalized annular lichen planus is rarely described and is characterized by generalized flexural eruptions without involvement of oral mucosa. A 43-year-old male presented with mildly pruritic erythematous to brownish annular macules, confluent patches with peripheral elevated rim for 5 months. The annular lesions involved abdomen, back, upper and lower extremities, predominantly distributed on flexural areas such as both axillae, inguinal areas and popliteal fossae. Histopathologic features from abdomen lesion were compatible with lichen planus. The patient was treated with methylprednisolone, hydrochloroquine and dapsone for 8 weeks and all erythematous lesions disappeared with remaining marked hyperpigmentation.

한정현(Han Jung Hyun),김혜숙(Kim Hey Souk) 우리말교육현장학회 2016 우리말교육현장연구 Vol.10 No.1

이 연구는 융복합교육의 시대 흐름에 따라 효과적인 평가 유형은 어떠해야 하며 구체적인 성취기준은 무엇인가에 대한 탐구이다. 이를 위하여 먼저 융복합적 국어과 평가에서 요구되는 핵심역량이 무엇인가를 살폈다. 핵심역량은 오늘날 교육과정의 기반을 이룰 만큼 교육의 목표로 자리 잡았다. 따라서 기존 논의를 바탕으로 해당 내용을 추출하는 과정은 평가의 구현과도 밀접하게 연관되어 있다. 그리고 융복합교육의 다양한 실천 방법 중 국어과 평가에 적용할 수 있는 것으로 주제 중심 모형을 선택하였다. 주제 중심 모형은 국어과에서 다른 교과들을 무리 없이 수용하여 학습자들에게 실천적인 과제를 부여하는 데 가장 적합하다고 보았다. 이와 함께 평가의 방향을 제시하고 국어과 융복합교육의 구체적인 평가 예시를 담기 위해 노력하였다. 학습자의 과정과 결과를 모두 확인하면서도 융복합이 원만하게 이루어지도록 기존 수행평가와 성취평가의 장점들을 종합하였다. 특히 국어과의 표현하기를 주제로 융복합적인 과제를 선정하고 이에 대한 구체적인 성취수준을 제시해 보았다. This study is a search for the effective evaluation types and the specific achievement standards following up the trend of Yungbokhap Education. The evaluation is perceived as the most objective indicator of the value of Teaching-Learning. And to keep up with the stream of Yungbokhap Education, the evaluation is demanded to be able to verify the whole process and results of learning in an integrated form of various subjects. To this end, key competency that is required to achieve convergence-type Korean language evaluation has been examined. Today, key competency has established itself as a goal of education, constitutive the base of school curriculum. Therefore, based on the existing discussion, the process of extracting the contents of the competency is also closely related to the implementation of evaluation. Among the various ways of practice of Yungbokhap Education, Theme-based model has been chosen to be implementation applied to Korean language evaluation. The Theme-based model is considered to be most suitable to assign a practical task to learners attracting the contents of other subjects to Korean language classes without difficulty. The direction and concrete examples of Korean language in Yungbokhap Education has been presented. The advantages of existing Performance Assessment and Achievement Standard Assessment have been combined so that Yungbokhap is successfully carried out while verifying both the process and results of learning. In particular, some convergence-type tasks about expressing have been selected, and detailed achievement levels for them presented. This start-up study would be a cornerstone of an evaluation-model in accordance with the purpose of the Yungbokhap Education.

Background: Acne is a common follicular inflammatory dermatosis affecting the pilosebaceous unit. The representative organism isolated from the acne lesion is Propionibacterium acnes, but other aerobic organisms, such as Staphylococcus epidermidis have also been isolated. The exact role of aerobic bacteria in the pathogenesis of acne remains controversial, but several reports have shown that these microorganisms are important in the development of acne lesions and affect acne severity by their involvement in the inflammatory process. Objective: The purpose of this study was to investigate the clinical features associated with aerobic microorganisms isolated from inflammatory acne and to identify antibiotic resistance. Methods: We examined the species of bacteria aerobically and anaerobically isolated from patients with inflammatory acne and determined the relationship between antimicrobial resistance of the isolated aerobic organisms and clinical characteristics in 186 patients. Results: P. acnes was cultured in 40.86% of the patients. Enterobacter aerogenes (4.30%), S. capitis species (6.45%), S. aureus (3.76%), S. hominis (2.15%), Serraita marcescens (1.08%), Klebsiella oxitoca (1.08%), S. lugdunensis (1.08%), S. auricularis (0.54%), S. hyicus (0.54%), S. simulans (0.54%), and S. saprophyticus (0.54%) were also cultured. Among the aerobes isolated from lesions, S. epidermidis was the most common (43.0%) and showed higher resistance to gentamicin (57.5%), ampicilin (45.0%), erythromycin (40.0%), and clindamycin (30.0%) than previous reports. The disease duration in the S. epidermidis group resistant to gentamicin, erythromycin, ampicilin, and clindamycin was longer than that in the susceptible group. Conclusion: These results revealed the recent increase in antibiotic resistance of S. epidermidis in patients with acne. Antibiotic resistance of aerobes in patients with acne have a tendency to increase based on disease duration. (Korean J Dermatol 2011;49(8):676∼682)

한정현 ( Jung Hyun Han ),김혜숙 ( Hey Souk Kim ) 한국어교육학회(구 한국국어교육연구학회) 2013 국어교육 Vol.0 No.143

The purpose of this study is to analyze the correlation between Listening and Speaking and the Literacy and consider how to apply it to the Korean language education. In general, ``Literacy`` means the ability to read and write. However, the original meaning of Literacy has gradually expanded because of the rapid change of education environment. One of the most notable aspects of the expansion is the combination of Listening and Speaking skills with Literacy. In order to improve communication abilities, the harmony of existing Literacy and Listening-Speaking abilities, Oracy, is very important. Therefore, correlation between Literacy and Oracy was investigated for more specific analysis and the study of the Korean Language curriculum was done. In particular, the immanent meaning of Literacy in High School ``Narration`` was studied and the goal of Listening and Speaking Literacy education was suggested.

한정현(Han, Jung-hyun) 한국조형디자인학회 2018 조형디자인연구 Vol.21 No.4

현대 한국사회는 사회적, 기술적으로 급격한 변화를 경험하고 있다. 사회적으로는 1인가구 증가로 대표될 수 있는 가족구성 변화가 나타나고 있고, 정보통신기술(IT)및 사물인터넷(IoT)의 전방위적 확장으로 과학기술문명의 변화가 진행 중이다. 이러한 변화는 새로운 가능성과 함께 여러 과제를 한국사회에 던지고 있다. 하지만 아직 IoT 기술이 탑재된 1인가구 맞춤형 가구 제품은 개발되지 않고 있다. 본 논문은 1인 가구 맞춤형 가구디자인과 IT와 IoT 기능이 탑재된 가구 디자인을 조사 및 분석하였다. 최종적으로 IoT 기술이 탑재된 1인가구 맞춤형 의자 디자인을 제시하였다. 제작된 의자에는 모바일 디바이스가 장착되어 컨텐츠 뷰어와 상호소통이 가능하다. 추후 사용자 인지 기능이 강화된 맞춤형 소프트웨어까지 개발된다면 제품의 활용도가 증가할 것으로 기대된다. Current Korean society is undergoing a radical restructuring in its family system in terms of a growing number of single families. At the same time, revolutionary changes are brought to modern civilization through the development of IT (Information Technology) and IoT (Internet of Things) technologies. Such changes have sparked the development of a large body of multi-functional household electronics and furnitures. However, furniture design for single families using IoT technology has not yet been well investigated or developed. In this study, we investigate furnitures developed for single-families and products where It and IoT technologies are embedded. Finally, we develop a chair design for single-family with IoT technology. A mobile device is installed to the chair to enable contents viewing and communication. With a parallel development of human cognition function, the applicability of the chair is expected to increase.

한정현 ( Han Jeong Hyun ),박정윤 ( Park Jeong Yun ) 한국가족관계학회 2022 한국가족관계학회지 Vol.27 No.3

연구목적: 본 연구는 대학생이 지각한 부모의 부부관계와 자기관이 이들의 결혼 의향 정도에 미치는 영향을 살펴보기 위한 목적에서 수행되었다. 연구방법: 이를 위해 전국의 대학교에 재학 중인 미혼인 대학생 342명을 대상으로 자료를 수집하였으며, 수집된 자료는 SPSS 26.0 프로그램을 사용하여 분석하였다. 연구결과: 본 연구의 주요 결과는 다음과 같다. 첫째, 대학생들의 결혼 의향은 정서적 결혼 의향이 가장 높게 나타났고 기능적 결혼 의향, 당위적 결혼 의향 순으로 나타났다. 둘째, 대학생이 지각한 부모의 부부관계 중 심리적 조화는 정서적, 당위적, 기능적 결혼 의향에 유의한 정적 영향력을 미쳤으며, 갈등과 권위는 당위적, 기능적 결혼 의향에 부적인 영향을 미치는 것으로 확인되었다. 자기관은 상호의존적 자기관과 독립적 자기관 모두 정서적, 당위적, 기능적 결혼 의향에 모두 유의한 정적 영향을 미치는 것으로 나타났다. 셋째, 결혼 의향에 관련 변인들이 미치는 영향력을 살펴본 결과, 정서적 결혼 의향에는 성별과 부모의 부부간 심리적 조화가 영향을 미쳤고, 당위적 결혼 의향에는 성별, 종교, 주관적 경제 수준, 부모의 부부간 심리적 조화 및 갈등과 권위, 상호의존적 자기관이 유의한 영향을 미쳤다. 기능적 결혼 의향에는 성별, 부모의 부부간 심리적 조화 및 갈등과 권위, 상호의존적 자기관의 영향력이 유의했다. 결론: 본 연구는 인구사회학적 특성, 가족 요인인 지각된 부모의 부부관계와 개인적 특성 요인인 자기관이 모두 종합적으로 대학생의 결혼 의향에 유의한 영향력을 미칠 수 있다는 점을 밝혔다는 데 의미가 있으며, 성인의 발달과업 중 하나인 결혼과 관련하여 성숙하고 건강한 태도를 확립하기 위해 상담 현장에서 이에 맞는 프로그램 개발의 필요성을 시사한다. Objectives: This study was conducted to examine the effect of parents’ marital relations perceived by university students and students’ self-construal on the degree of marriage intentions. Method: Data was collected from 342 unmarried male and female students enrolled in universities nationwide and analyzed using the SPSS 26.0 program. Results: The main results of this study are as follows. First, the students’ marriage intentions were the highest in emotional marriage intentions, followed by functional marriage intentions and normative marriage intentions. Second, it was confirmed that the students’ perception of the psychological harmony among their parents’ marital relations had a significant positive correlation with emotional, normative, and functional marriage intentions. While conflict and authority had a negative correlation with normative and functional marriage intentions. It was found that both the interdependent self-construal and the independent self-construal had a significant positive correlation on emotional, normative, and functional marriage intentions. Third, as a result of examining the effect of related variables on marriage intentions; gender and their parents’ psychological harmony influenced emotional marriage intention. Gender, religion, subjective economic level, psychological harmony, conflict and authority of parents, and interdependent self-construal had a significant influence on normative marriage intentions. In addition, gender and their parents’ psychological harmony, conflict and authority, and the influence of interdependent self-construal showed significant results in functional marriage intentions. Conclusions: The results of this study confirmed that demographic and sociological characteristics, students’ perception of parental marital relationships as family factors, and self-construal as personal characteristics can all have a significant influence on university students’ marriage intentions. In particular, the influence of these factors may appear differently depending on the specific type of marriage intentions. It provides a discussion point to help university students have healthy perceptions and intentions on marriage. The results of the study suggests the necessity of developing a suitable counseling program in order to establish a mature and healthy attitude related to marriage, one of the developmental tasks of adults.

人性敎育과 小學의 現代的 收容

韓正鉉(Han, Chong-Hyun) 성신여자대학교 교육문제연구소 1996 교육연구 Vol.30 No.-

본고는 첫째 초등학교에서부터 대학에 이르기까지 소학을 위시한 우리의 고전을 윤리과목으로 채택할 것을 제창한다. 둘째, 인성교육에 회초리를 이용해야 한다. 셋째, 현재의 성균관 대학을 국립대학으로하여 민족 대학의 면모를 갖추자는 것이다. 넷째, 현대 산업사회에 대한 인식이다. 다섯째, 그동안 교육부의 교육시책은 국민들의 기대에 부흥하기 보다는 오히려 우려를 더해가는 쪽으로 진행되어 왔다. Our teenagers social acts are getting rude, selfish, impolite and crucil, since they take a hard work at school including not only social but also modern moral education. Some experts pointed out such phenomena is possibly due to the rapid industrialization and as a result to mammonism rather to a lack of lack of education. Our people had been called as Orient Morality Kingdom state that is the most moral people of others in Far East states including China. The chief reason so called was that we had "Sowhak" a custom code of moral behaviors for the teenagers but we abandon Japanese educational assimilation. European natural law thought and Foreign invasion interrupted our traditional thought and moral education coherence for about one hundred years. Now we Korean people has be come the most ugly one in the world. Industnalization could also be added to theses severe moralistic trials. Despite rapid industrialization discouraging experiences these still remain distinguished exponents of the view that man at the primitive level is innately good and that it is the social and political organization of civilized life which has introduced. The seds of violence and disorder and which in their turn have led to systems of legal coercion. Each of us knows from his own experience that his fellows are, on the whole, kindly and well-intentioned. Most of the friction and disccored of our lives are obviously the result of such exasperations and confction and disccord of our lives are obviously the result of such exasperations and conflicts as civilzation itself creates. Envy, malica and all uncharitableness usually have for the object of their expression some artificial aim, form the pursuit of which our geenagers are not exempt. I urge the only way to take up our old Orient Morality Kingdom is to take Sowhak as a moral custom code for teenager education again primary, middle and high school as one hundred years before, The contents Sowhak are so-called "Sam Kang Olyun" that is, courteous behaviour between me and king, parents, brothers, friends, superior, imperior, wife etc. The filial piety is the most highest value of these courteous behaviours. It is presented usually as "When one would he filial, one's parents are gone", or "a son is always too late to think of his parents". filial piety form old time evalued by korean mentality prevails all others spiritual values and present korean identity. This spiritual value had been of traind through old custom presented and provided by our eternal moral text "Sowhak".
