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.

2007개정 국어 교과서의 ‘식사문’ 쓰기 단원에 대한 일고찰

한정현(Han, Jung-Hyun) 우리말교육현장학회 2013 우리말교육현장연구 Vol.7 No.1

2007개정 국어과 교육과정에는 그동안 다루지 않았던 ‘식사문’이라는 장르의 글쓰기가 포함되었다. 그리고 16종 검정 <국어> 교과서에는 식사문 쓰기와 관련한 내용이 모두 소단원으로 제시되었다. 식사문은 공식ㆍ비공식적인 글을 모두 아우르는 글쓰기의 하나로 사회적 관계 형성에 큰 역할을 하지만, 이에 대한 면밀한 검토 과정조차 없이 2011개정 국어과 교육과정에서는 자취를 감추었다. 여기에서는 식사문 쓰기 교육이 필요하다는 전제 아래 교과서에서 그 구현 양상이 어떻게 이루어지고 있는지를 살폈다. 특히 대단원을 중심으로 식사문 쓰기 관련 소단원이 다른 소단원들과 어떠한 방식으로 통합을 이루고 있는지 탐구하고 통합의 적절성에 대해 언급하였다. 그리고 16종 <국어> 교과서의 식사문 관련 학습활동에 나타난 발문들을 쓰기를 전제로 하여 유형별로 나누고, 이에 대한 분석과 제언도 해 보았다. Siksamun(Public nature of writing)', genre of writing, which have not covered before were included in the revised Korean curriculum in 2007. And all 16 kinds of Government-approved <Korean> textbooks have the 'Siksamun(Public nature of writing)' writing-related units. 'Siksamun(Public nature of writing)' that encompasses both formal and informal writing, plays a large role in the formation of social relationships. But even without the careful scrutiny review it was removed from the 2011 revised Korean curriculum. In this paper, on the assumption that 'Siksamun(Public nature of writing)' writing education is needed, whether it is implemented in the textbooks were reviewed. In particular, this study was reviewed whether there is the integration which centered upper unit between 'Siksamun(Public nature of writing)' writing related units and the other units. Furthermore, the relevance of integration was mentioned. Also, questions which appeared in learning activities are categorized by type, and analyzed 'Sksamun' writing-related questions in 16 kinds of textbooks whether they are reasonable to achieve the goal of Korean writing education.

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.

Ambulatory phlebectomy is a procedure for the removal of superficial veins through small incisions. It is commonly used to treat varicose veins in the legs. Compared with alternative procedures such as sclerotherapy and laser therapy, phlebectomy is less likely to cause conditions such as hyperpigmentation, cutaneous necrosis, superficial phlebitis and deep vein thrombosis. Phlebotomy is cosmetically effective for the removal of facial reticular veins, which are currently cosmetic issues. The first patient, a 42-year-old woman, presented with a 3 cm sized bluish linear patch on her right lower eyelid. Color-flow duplex ultrasonography confirmed that it was dilated superficial vein. The second patient, a 51-year-old woman, came to our clinic with reticular vessels on the nasal dorsum and left lower eyelid. Both patients were treated with phlebectomy and they showed a cosmetically satisfactory outcome. This paper reports on two cases of facial reticular vessels that were treated with phlebectomy and the course of the procedure. (Korean J Dermatol 2011;49(1):40~44)

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)

Background: Lupus miliaris disseminatus faciei (LMDF) is a rare granulomatous disease characterized by eruption of discrete red-brown, dome-shaped papules, predominantly in the lower eyelid. Histopathologically, LMDF could present as caseous necrosis in the central area with granulomas composed of epithelioid cells and giant cells. The pathogenesis of LMDF remains controversial. Some suspect LMDF as a kind of cutanoeus tuberculosis, but others believe LMDF to be a variant of granulomatous rosacea or sarcoidosis. Objective: This study aimed to investigate the clinical and histopathologic features of LMDF. Methods: We reviewed the medical records, clinical photographs, and histopathologic slides of 30 cases of LMDF that were evaluated in our department between February 1991 and May 2009. Results: The average age of the affected patient was 34.6±10.9 years and the ratio of male-to-female patients was 3.3:1. The most common sites of involvement with LMDF was the eyelid (86.7%). cheek (76.7%), philtrum (60.0%), and glabella (56.7%). On histopathologic examination, the epithelioid granulomas had a connection to pilosebaceous structures in 66.7% of the cases. Follicular rupture (33.3%), perifollicular granulomas composed of naked tubercles (53.2%), and sarcoidal granulomas with abscesses (23.3%) were noted. Characteristic caseous necrosis occurred in 7 cases (23.3%). The duration of LMDF was 2 years in 26 cases (86.7%) and the lesion improved leaving scar in 21 cases (70%). Conclusion: We identified the histopathologic changes of LMDF as a function of disease duration. Connections of pilosebaceous units with granulomas were commonly observed. It will be helpful to understand the pathophysiology of LMDF.

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.

Extramammary Paget`s disease (EMPD) is an unusual neoplasm that affects apocrine gland-bearing skin, such as the vulva, perianal region, scrotum, and penis. However, EMPD has been rarely observed in the non-apocrine, gland-bearing regions; such cases are referred to as ectopic EMPD. We present a case involving a 46-year-old man in whom ectopic EMPD affected the scalp. Although the clinical appearance was suggestive of pagetoid Bowen`s disease, EMPD was confirmed by biopsy and immunohistochemical studies. In Korea, there has been only one report of EMPD occurring in the scalp. EMPD of the scalp is extremely rare, with few reported cases. We report a case EMPD of the scalp with a review of the literature. (Korean J Dermatol 2011;49(6):550∼553)
