본 연구는 최근 차세대 플랫폼으로 주목받고 있는 인공지능 스피커의 사용의향과 관련, 확장된 기술수용모델을 적용하여 잘 설명할 수 있도록 독립변수에 의인화, 서비스다양성, 이용 용이성, 인지된 사생활 침해를 포함하였고, 매개변수로 인지된 유용성과 인지된 즐거움을 포함한 모델을 설계하였다. 본 연구의 결과는 다음과 같다. 첫째, 인공지능 스피커의 의인화, 서비스 다양성, 이용 용이성은 인지된 유용성에 정(+)의 영향을 미쳤고, 인지된 사생활 침해는 인지된 유용성에 부(-)의 영향을 미쳤다. 둘째, 인공지능 스피커의 의인화, 서비스 다양성, 이용 용이성은 인지된 즐거움에 정(+)의 영향을 주었고, 인지된 사생활 침해는 인지된 즐거움에 유의한 영향을 미치지 못했다. 셋째, 인공지능 스피커를 사용함으로써 인지된 유용성과 인지된 즐거움은 이용 의향에 정(+)의 영향을 주었고, 인지된 즐거움이 인지된 유용성보다 이용 의향에 미치는 영향이 훨씬 강한 것으로 파악되었다. 마지막으로 경로분석 결과, 인공지능 스피커의 이용 의향에 가장 영향력이 높은 경로는 ‘서비스 다양성→인지된 즐거움→이용 의향’인 것으로 파악되었다. This study included anthropomorphism, service diversity, ease of use, and perceived privacy invasion in independent variables in order to be able to explain well by applying an Extended Technology Acceptance Model in relation to the intention of artificial intelligence speakers, which are recently attracting attention as a next-generation platform. In addition, a model including perceived usefulness and perceived enjoyment as parameters was designed. The results of this study are as follows. First, the anthropomorphism, diversity of services, and ease of use of artificial intelligence speakers had positive(+) effects on perceived usefulness, and the perceived privacy invasion had a negative(-) effects on perceived usefulness. Second, the anthropomorphism, diversity of services, and ease of use of artificial intelligence speakers had positive(+) effects on perceived enjoyment, and perceived privacy invasion did not significantly affect perceived enjoyment. Third, the perceived usefulness and perceived enjoyment by using the artificial intelligence speaker had positive(+) effects on the intention to use, and the perceived enjoyment had a much stronger effect on the intention to use than the perceived usefulness. Finally, as a result of path analysis, It was found that the most influential path for the intention to use artificial intelligence speakers was ‘service diversity → perceived enjoyment → intention to use’.

한국 전통 목공예 전문 인력 양성과 전망

이관섭(Lee Kwan seop) 한국조형디자인학회 2016 조형디자인연구 Vol.19 No.1

전통적 목공예의 가장 큰 특징은 손에 의해 만들어 진다는 것이다. 이 手工性은 戰後 기계를 내세운 근대 산업혁명이라는 흐름 속에서도 그 脈은 꾸준히 이어져 오고 있다. 일단 전통적 목공예 기술은 無形의 자산으로써 한번 脈이 끊어지면 다시는 소중한 전통적 공예품으로 되살아나기란 불가능 한 일이다. 한국전쟁 후 경제개발이라는 산업화 정책 하에 청, 장년층의 離農과 도시 집중화 현상, 현대산업 지향과 어우러져 전통공예의 심각한 후계자 난을 발생시켜 목공예 산업은 쇠퇴의 길로 접어 들 수밖에 없었다. 이러한 한계성을 극복하고 전통 기, 예능의 기술과 기법이 전승될 수 있도록 여러 가지 제도나 전수교육 및 방법을 다각도로 모색해 보고자 하는데 논지에 의미를 두었다. 傳統木工藝는 두 가지 측면으로 재해석될 수 있는데 하나는 傳承되어 온 기술과 창의가 변질되거나 도태되지 않도록 보존가치에 비중을 둔 유ㆍ무형의 文化財的 意味를 전통의 보존과 전승에 있다고 한다면, 또 하나는 傳來되어 온 전통목칠공예문화를 바탕으로 視覺的 特質化를 시킬 수 있는 藝術과 技術의 고유한 趣向으로써 시대에 따라 생산방식과 표현기법이 달라져도 그 시각적 기호나 이미지에서 관찰될 수 있는 傳統 工藝産業으로 구분 할 수 있겠다. 한국의 「전통공예 산업진흥에 관한 법률 案」과 일본의 「전통적 공예품 산업의 진흥에 관한 법률」을 통해서 정책과 제도에 대해 살펴보았다. 국가적인 지원과 제도의 입법화를 통한 통합된 정책과 투철한 장인정신을 가진 기, 예능인을 양성하여 전통목공예의 再現性과 創造性을 조화롭게 발전시켜 전통예술과 경제 활성화에 적극 동참시켜나가기 위해서는, 전통공예의 수련과정을 체계화하고, 단계적인 교육을 위해 과학적인 교재 개발도 동시에 이루어 져야 할 것으로 본다. The most characteristic of traditional wood crafts is to be made by hands. The hand-made property is handed down steadily in a flow of the Modern Industrial Revolution with machines after wars. The traditional wood crafts technology is an immaterial asset. Therefore, it is impossible to revive as a valuable traditional crafted product if its transmission is not connected with the next generation. After Korean War, an intention of modern industry got joined together with the flow of the youth and the middle-aged moving from a rural community to a city under the policy of industrialization, which caused serious difficulties in the traditional crafts’ transmission. Therefore, the wood crafts industry could not help having dwindled away. The purpose of the study was to grope various systems or transmission education and methods in various ways so that traditional function and artistic accomplishments’ technology and skill may be handed down by overcoming limits as above. The traditional wood crafts can be review in two sides. One is to place material/immaterial cultural assets’ meaning on traditional preservation and transmission so that the handed-down technology and creativity may not be deteriorated or weeded out. The other is to classify it to the traditional crafts industry that it is possible to observe its visual taste or image even if production methods and expression techniques are changed according to the times as the original fondness of arts and technology for visual characterization on the basis of the handed-down traditional wood/lacquer crafts culture. Thus, the study examined policies and systems for the traditional wood crafts through [Legislative Bill for Traditional Crafts’ Industrial Promotion] of Koreaand[TraditionalCraftedProductsIndustryPromotionAct]ofJapan. Traditional crafts’ training course should be systematized to train craftsmen and artists with a pure workmanship by integrated policies through support of the government and legislation of systems for them and so that they may have a positive participation in traditional arts and economic revitalization by developing traditional wood crafts’ reproducibility and creativity harmoniously. Also, a scientific develop of textbooks should be also realized for a phased education.

Linear Synchronous Motor has a large airgap comparing with rotary-type motor and especially, Permanent Magnet Linear Synchronous Motor(PM-LSM) which uses permanent magnet as a magnetic field, has a very large effective magnet airgap owing to permanent magnet structure. Accordingly, in case of 2-0 analysis of the motor, the analysis error becomes large because leakage flux by which normal direction of the analysis region can not be considered. In this paper, the characteristic of PM-LSM for Maglev vehicle is analyzed exactly by 3-D Finite Element Method(3-D FEM). As the result, the effect of lateral-direction airgap magnetic flux density distribution on the analysis precision has been investigated and the motor characteristics according to primary motor parameter have been also made clear quantitatively. The accuracy of 3-0 FEM has been confirmed by comparing the calculated results with the experimental results.

Purpose: This study aimed to determine which factors are related to perforated appendicitis. We also conducted a survey to identify the causative organism. Methods: From January 2011 to December 2014, 569 pediatric patients (322 male) younger than 19 years old who underwent an appendectomy due to acute appendicitis at Hallym University Sacred Heart Hospital were enrolled. Patients' medical records were reviewed retrospectively to determine their clinical manifestations, laboratory and imaging results, and pathogens. Results: About 127 patients (22%) had perforated appendicitis. The rate of perforated appendicitis in preschool, late childhood, and adolescent ages were 50%, 27%, and 16.8%, respectively. The risk factors of perforation were high C-reactive protein levels and the presence of appendiceal fecalith (P<0.001). Of the 24 samples of peritoneal fluid and periappendiceal pus that were collected intraoperatively, 16 were culture positive. The most common pathogen was Escherichia coli (n=10), and others were Pseudomonas aeruginosa, Streptococcus spp., and Staphylococcus spp. Conclusions: The perforation rate of appendicitis among patients younger than 5 years old was 50%, and this decreased in proportion with age. Clinicians should be aware of the possibility of perforation when patients with appendicitis have high C-reactive protein levels or the presence of appendiceal fecalith on imaging.

Far reducing medical radiation exposure and managing patient doses, Entrance surface doses(ESDs) were measured at Diagnostic Radiology Department in ASAN medical center, also we determined and compared with the Diagnostic Reference Level(DRL) of some other countries. ESDs were measured far the most common types of X-ray procedures, such as chest PA, lumbar spine AP, lumbar spine lateral, Pelvis AP, Skull PA. ESDs were measured by Glass dosimeter and Unfors Xi meter. Those were applied collimation center of phantom's entrance skin surface. The results of ESDs were compared Glass dosimeter with Unfors Xi meter. Those were measured within 5% statistical difference. It seemed well agreement at two devices. In most cases ESDs measured far the different types of X ray procedures were found to be lower than the DRL of IAEA, but ESDs on chest PA, lumbar spine AP, lumbar spine lateral, Pelvis AP, Skull PA were proximity ar excesses at DRL of advanced country. Through this study, we need an investigation and improvement at present diagnostic radiology exam system. Also, radiologists make an effort to reduce patient dose and having a technical skill.

Obstruction of the extrahepatic bile ducts is the most common cause of conjugated hyperbilirubinemia in early infancy. More than 90% of such obstructive lesions are accounted for by extrahepatic biliary atresia. A rare lesion is obstruction of the common duct by impacted, thickened secretions and bile. Bile plug syndrome is defined as extrahepatic obstruction of the bile ducts by bile sludge in term infants without anatomic abnormalities, congenital chemical defects of bile, or hepatocellular lesions. Obstruction of extrahepatic ducts by plugs of biliary material apperas to be due to the inspissation and precipitation of bile and mucus within the lumen of the ducts. Cholestasis and precipitation of bile develop in association with abnormal composition of bile in cystic fibrosis, hepatocellular damage, prolonged erythroblastic jaundice, altered biliary dynamics with total parenteral nutrition, gut dysfunction, diuretic therapy, exchange transfusions and perinatal hemolysis. In those cases, the term inspissated bile syndrome is used. The clinical and laboratory findings in bile plug syndrome are identical to those observed in biliary atresia and choledochal cyst. The diagnosis can be suspected based on the findings of clinical and laboratory examinations together with hepatobiliary imaging, ultrasonography, radionuclide scan and liver biopsy. We experienced a case of spontaneous resolution of bile plug syndrome in a 4-year-old girl. We report this case with brief review related literatures.

This paper presents the efficient 2-D linear brake analysis model which can compensate the lateral leakage flux by changingng the airgap length and magneto-motive force(MMF). The linkage flux of the 2-D analysis is larger than that of 3-D analysis. This is caused by the assumption in 2-D analysis that geometric and physical values are constant along the perpendicular direction(z) to the analysis region. The equivalent MMF have been calculated from the linkage flux difference between the 2-D and 3-D analyses which are performed at zero velocity. The performances of the linear brake have been analyzed effectively by using the compensated 2-D models without using 3-D FEM.
