정제명,왕순주,안무업,박재형,유기철,박준석,강재구,제프리 아놀드 대한응급의학회 1999 대한응급의학회지 Vol.10 No.4

Background : To assess the current level of development of emergency medicine (EM) systems in Asia. Method : Survey of EM professionals from 12 Asian countries during a 90-day period from August to November 1998. 12 EM professionals from 12 Asian countries completed the survey. All participants were physicians. 7 participants (58%) gave presentations at an international EM conference during the study period. Respondents completed a 103 question questionnaire about the status of EM specialty, academic, patient care, information and management systems and the factors influencing the future of EM in their countries. Results : 92% of respondents stated that their countries have hospital-based emergency departments (ED). More than 80% of respondents reported that their countries have EMS systems and ED systems for trauma care and patient transfer. More than 70% stated that their countries have national EM organizations, EM research, national EMS activation phone numbers, ED systems for pediatric emergency care, emergency physician (EP) training in ACLS and ATLS and peer review. More than 60% reported official recognition of EM as an independent specialty status, ED triage systems and systems for customer service. More than 50% reported EM residency training programs, EM journals and EP ability to perform rapid sequence intubation (RSI). 50% reported EP ability to perform thrombolysis for acute MI and 33% reported EP ultrasonography. 92% felt that a lack of funding posed a moderate or great obstacle to the future development of EM in their countries. Conclusions : Many essential systems of EM now exist throughout Asia. In the systems of administration and emergency medical information in many countries, there are some parts to be developed further.

여성용 춘추복지의 태에 관한 연구 (제1보) : 태의 주관적 평가척도 개발을 중심으로 Development for the Subjective Hand Evaluation Scale

홍경희,김재숙,박춘순,박길순,이영선,김재임 한국의류학회 1994 한국의류학회지 Vol.18 No.3

KES-F system is widely used in hand evaluation, however, it has encountered some challenges, such as the overlapping of primary hand value, lack of predictability in case of women's thin dress, difficulties in communication due to complexity of primary hand expression and cultural differences in subjective evaluation. Therefore, this study was intended 1) to find out the Korean primary hand expressions (factors) of the overall concept of fabric hand associated with women's spring-fall dress fabrics, 2) to develope the fabric hand attributes of those fabrics and 3) to show whether there are any differences between Korean textile experts and non-experts in terms of the concept of fabric hand descriptors of hand attributes. Data base of hand descriptors were collected by extensive interview 60 experts and 10 non-experts using 110 spring-fall dress fabrics. Finally, hand of selected fabrics was assessed by 205 experts and 265 non-experts using 7-point scale of 26 descriptors based on the data base. Subjective ratings were analyzed by common factor analysis with varimax rotation. It was found that Korean primary hand expression indicated rather simple property, hence, did not equate exactly with Japanese experssion(e.g. koshi, shinayakasa, etc.) which contains several material properties. There were differences in stretch & resilience, especially liveliness, between the judgement of non-expert than to experts. Surface-related category was more important to non-experts than to experts. Slight differences were found between both groups in terms of preferred descriptors. Important descriptors as a rating scale were suggested.

기업의 효율적인 정보시스템 구축은 정보화 사회에서는 반드시 필요하다.또한 기업의 성장 규모, 기업의 요구 사항, 기업의 보다 향상된 업무를 위해 시스템을 능동적으로 구현, 확장, 재구성되어야 한다.이에 정보의 연계, 최신 정보의 효율적 관리를 이용한 구체화와 정보화를 유지할 수 있다.이를 위하여 중소 업체에서는 한 번에 많은 투자를 해야되는 종합 정보화 시스템보다는 생산 관리, 인사 관리, 회계 관리 등 각각에 대한 정보화를 위해 가장 기본적인 프로그램들을 업체의 특성과 차별성을 고려하여 실용 업무에 보다 적합한 자동화 시스템구성의 필요성이 강조된다.따라서 이들 시스템간에 서로 정보를 교환하고, 의사결정을 하는 종합 관리 시스템을 구축하여야 하는데, 이를 위하여 기존에 개발된 영업관리, 생산 관리, 인사 관리, 회계관리 프로그램들을 통합하는 것이 새로운 시스템을 개발하는 것보다 경제적, 기능적 측면에서 매우 유리하다 할 것이다. 본 연구에서는 (주)두양금속의 기존에 사용중인 영업관리, 생산 관리, 인사 관리, 회계 관리 시스템을 통합하고자 이미 구축된 시스템을 분석하고 각각의 독립된 업무를 연계하여 효율적인 정보 관리 시스템을 구축하는 것에 목적을 두고있다.

장기적인 상아질 접착의 내구성 악화는 접착층과 혼성층의 친수성 부위에서의 가수분해에 의해 일어나는 것으로 보고 되고 있다. 본 연구의 가설은 콜라겐 망상체를 유기용매로 프라이밍하면 콜라겐 조직을 붕괴시키지 않고 수분을 밀어내고 소수성 단량체와 유기용매로 이루어진 접착제가 침투하여 접착강도를 얻을 수 있다는 것이다. 두 소수성 단량체인 Bisphenol-A-glycidylmethacrylate (Bis-GMA)와 triethyleneglycol dimethacrylate (TEGDMA)를 아세톤, 에탄올 또는 메탄올에 용해시켜 세 가지의 실험용 접착제를 준비하였다. 산 부식과 수세과정 후에, 접착제를 습윤 상아질 표면(습윤 접착)이나 동일한 용매로 프라이밍 된 상아질 표면(용매 프라이밍 접착)에 적용하였다. 48시간 후와 1개월 후, 및 10.000회의 열순환 후에 미세인장결합강도를 측정하였다 접착계면은 주사전자현미경을 이용하여 관찰하였다. 접착방법에 무관하게 대부분의 시편의 접착계면예서 잘 발달된 혼성층을 관찰할 수 있었고 가장 높은 평균 미세인장결합강도는 에탄올을 포함하는 접착제의 48시간 후 시편에서 관찰되었다. 용매를 이용하여 프라이밍하는 접착 방법에서는 에탄올이나 메탄올을 포함하는 접착제에서 열순환 후에 미세인장접착강도가 증가하는 경향을 보였다. 그러나 습윤 접착의 경우에는 시효처리 후 미세인장결합강도의 증가가 관찰되지 않았다. 본 연구에서 에탄올을 이용한 상아질 프라이밍으로 우수한 접착력을 얻을 수 있었고. 열순환 후 접착력이 더욱 증가하였다 Deterioration of long-term dentin adhesion durability is thought to occur by hydrolytic degradation within hydrophilic domains of the adhesive and hybrid layers. This study investigated the hypothesis that priming the collagen network with an organic solvent displacc water without collapse and thereby obtain good bond strength with an adhesive made of hydrophobic monomers and organic solvents. Three experimentaladhesives were prepared by dissolving two hydrophobic monomers bisphenol-A-glycidylmethacrylate (Bis-GMA) and triethyleneglycol dimethacrylate (TEGDMA), into acetone, ethanol or methanol. After an entching and rinsing procedure, the adhesives were applied onto either wet dentin surfaces (wet bonding) or dentin .surfaces primed with the same solvent (solvent-primed bonding). Microtensile bond strength (MTBS) was measured at 48 hrs, 1 month and after 10,000 times of thermocycles. The bonded interfaces were evaluated using a scanning electron microscope (SEM) Regardless of bonding protocols, weIl-developed hybrid layers were observed at the bonded interface in most specimens. The highest mean MTBS was observed in the adhesive containing ethanol at 48 hrs. With solvent-primed bonding increased MTBS tendencies were seen with thermocycling in the adhesives containing ethanol or methanol. However in the case of wet bonding, no increase in MTBS was observed with aging.

본 연구는 영화의상의 상징적인 표현성을 연구하기 위한 논문으로써, 대표적인 공포영화 <드라큐라>를 선정하여, 등장인물을 중심으로 인물의 성격이 의상을 통해서 어떻게 상징적으로 표현되었는지 살펴보고, 영화의 주제와 이미지, 반전을 암시하는 극적 효과로서의 의상 스타일을 실루엣과 색채, 디테일을 중심으로 분석하여 영화의상의 상징적인 의미를 살펴보았다. 영화 <드라큐라>는 예술적 완성도가 높은 작품으로 흥행에도 성공했으며, 시대물인 동시에 공포 장르로서 복식사적 고증을 바탕으로 한 디자이너의 창의적인 의상 스타일이 강조되었고, 神와 악마, 인간의 내면적 갈등을 주제로 한 이 영화에서 영화의 추상적인 주제를 상징적인 의상으로 표현하여 영화의상의 시각적, 심미적 효과가 부각되었다고 사료된다. 이와 같이 영화 <드라큐라>에서 표현된 의상스타일은 영화의상의 상징적인 가치와 더불어 공포영화의 완성도를 높이는데 기여하였음을 본 연구를 통해서 확인할 수 있었다. The Study on <Bram Stocker's Dracula>, one of most popular horror movies, examined closely how personalities of the characters were symbolized through their costumes, and then analyzed the consume as a dramatic effect suggesting theme, image and reversal of the movie focused on silhouettes, colors and details, in order to study symbolic expressions in fashions of the movie. The movie, <Bram Stocker's Dracula> with high artistic completion was successful in the box-office record and highlighted creative costume of the designer based on historical investigation of the costume as a horror genre as well as a historical movie, In this movie, on the theme of internal conflicts among God, Satan and human beings, it was thought that the visual and aesthetic effects of the costumes were highlighted by expressing in the movie,<Bram Stocker's Dracula> contributed greatly to not only enhancement of aesthetic and symbolic value but also accomplishment of the horror movie.

食用油脂는 健康維持에 必須的인 營養素이다. 그러나 食用油脂는 脂肪을 構成하는 脂肪酸의 種類와 攝取하는 量에 따라 健康을 保衛하는 必須的인 食品의 成分이 되기도 하고 有害한 影響을 끼칠 수도 있어서 脂質代謝와 關連된 疾病 뿐만아니라 老化를 促進하고, 乳房癌, 大腸癌等의 癌發生과도 關連된 것으로 밝혀져 있다. 本 硏究는 우리生活環境에서 食用으로 接할 수 있는 10種의 油脂에 對한 免疫生物學的인 活性에서 究明한 結果 對照群인 참기름食餌群에 比해 올리브유食用群은 全般的으로 體液性 및 細胞性免疫을 有意性있게 增加시켰으나, 大食細胞의 活性과 末梢循環白血球數는 有意性없는 減少를 보였고, 動物性 油脂인 牛脂食餌群과 植物性 油脂인 옥수수기름食餌群, 들기름食餌群, 米糠油食餌群, 大豆油食餌群, 菜種油食餌群 및 고추씨기름食餌群에서는 全般的으로 體液性 및 細胞性免疫, 大食細胞의 活性 및 末梢循環白血球數를 有意性있게 減少시켰다. This study was performed to investigate the effects of edible oils and fats on the immunobiological responses in ICR male mice. Ten groups of experimental diets, such as sesame oil diet, beef tallow diet, lard oil diet, olive oil diet, corn oil diet, perilla oil diet, rice polishing oil diet, soybeen oil diet, rape seed oil diet, and red pepper seed oil diet were fed adlibitum to the ICR male mice for 27 days. The results of this study were summarized as followings. 1. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes in sesame oil group were increased. However, the increasing rate of body weight and the weight retios of spleen and thymus to body were generally decreased. 2. Hemagglutination titer(HA) and rosette forming cell(RFC) of the beef tallow group and the lard group were significantly lower than the sesame oil group(P<0.01), but the lard group significantly increased Arthus reaction and delayed type hypersensitivity(DTH)(P<0.01). 3. Arthus reaction, DTH, and RFC of the olive oil group were significantly higher than the sesame oil group(P<0.01). 4. DTH of the corn oil group was significantly higher than the sesame oil group(P<0.01) whereas phagochyte activity was significantly lower(P<0.01). But no statistically significant differences were found between the two groups in the humoral immune response. 5. HA, PFC, DTH, RFC, phagocyte activity, and number of leukocytes of the perilla oil group and the rice polishing oil group were significantly lower than the sesame oil group(P<0.01). 6. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes of the soybeen oil group, the rape seed oil group, and the red pepper oil group were significantly lower than the sesame oil group(P<0.01).

We should maintain the maximum operation capacity for production facilities and find properly out the fault of each equipment rapidly in order to decrease a loss caused by its failure. The acoustic signals of a machine always carry the dynamic information of the machine. These signals are very useful for the feature extraction and fault diagnosis. We performed a fundamental study which develops a system of fault diagnosis for a pump. We obtained noises by a microphone, analysed and compared the signals converted to frequency range for normal products, artificially deformed products. We tried to search a change of noise signals according to machine malfunctions and analyse the type of deformation or failure. The results showed that acoustic signals as well as vibration signals can be used as a simple method for a detection of machine malfunction or fault diagnosis.
