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.

작동음의 분석을 이용한 펌프의 고장진단

박순재,이신영 한국공작기계학회 2003 한국생산제조학회지 Vol.12 No.6

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 signal 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.

급성대동맥박리증에서 수술전 경식도심초음파도의 역할

박성훈,원태희,원용순,한재진,안재호,이귀용 梨花女子大學校 醫科大學 醫科學硏究所 1999 EMJ (Ewha medical journal) Vol.22 No.1

급성대동맥박리증은, 특히 상행대동맥을 침범한 경우, 응급수술을 요하는 질환으로서 수술전 대동맥판의 손상여부, 질환의 범위, 내벽파열부위의 위치 및 가지혈관의 상태등을 파악하여 수술계획을 수립하여야 한다. 저자들은 상행대동맥을 침범한 3례의 급성대동맥박리증 환자에서 전산화단층촬영과 함께 수술전 또는 필요에 따라 수술후 경식도심초음파도를 시행하여 환자의 치료에 도움을 받았기에 문헌고찰과 함께 보고하는 바이다. Acute type A arotic dissection is a condition which requires emergency surgery. Surgeons want to know not only the extent of the disease but also the exact site of intimal tear as well as the presence of side branch involvement to plan the extent of surgery. Various non-invasive diagnostic tools(transthoracic and transesophageal echocardiography, conventional and spiral computed tomography and magnetic resonance imaging) and invasive angiography are available for the evaluation of the extent of dissection, site of intimal tear and side branch involvement. Each technique has its advantage and disadvantage. Especially, MRI has been accepted as a gold standard for the diagnosis of aortic dissection, but it is immobile and sometimes it cannot give us the information about the small intimal tear site. Transesophageal echocardiography has the advantage of movability and high resolution in addition to the ability of providing comprehensive information about the cardiac function. Because of these advantages, it has been widely utilized for the evaluation of patients with aortic dissection. We performed preoperative transesophageal echocardiography in addition to computed tomography in 3 cases of acute type A aortic dissection and report these cases with the review of articles.

겔화제로 녹두녹말, 감자녹말, 펙틴을 사용하여 당농도별 복숭아편을 제조하여 pH, 당도, 색도, 텍스쳐 및 기호성을 조사하여 품질특성을 검토하였다. 관능검사결과, 녹두녹말편이 감자녹말편보다 외관과 조직감에 대한 기호도가 높았으며, 펙틴 무첨가군 복숭아편을 더 선호하였다. 1% 펙틴첨가는 복숭아편의 기호도를 약간 감소시키는 것으로 나타났다. 기계적 검사는 녹두녹말편이 감자녹말편보다 조직감이 더 높았으며 펙틴 첨가군 복숭아편의 조직감이 더 높게 나타났다. 1% 펙틴 첨가의 효과는 복숭아편의 견고성과 씹힘성 등의 질감특성을 증가시켜 주었다. 기계적 검사의 탄력성은 관능검사의 매끈한 정도, 견고성, 외관의 기호도, 조직감의 기호도, 전반적인 기호도와 정적 상관관계를 나타내어 탄력성이 강할수록 기호도가 높게 나타났다. 색도는 펙틴첨가군이 높았으며 명도(L)는 녹두녹말편 적색도(a)는 감자녹말편이 높게 나타났다. 당 농도가 높을수록 명도(L)는 감소하였다. 관능검사의 전반적인 기호도에 가장 영향을 미치는 인자는 맛의 기호도, 조직감의 기호도, 견고성, 부착성, 맛 순으로 나타났다. This study was evaluate of chemical properties, textural characteristics and sensory properties, produced peach pyuns through the change of gelling agents such as mungbean starch, potato starch and pectin and of sugar density with 10%, 20% and 30%. Sensory evaluation was that peach pyun added mungbean starch was more preferable in appearance and texture than peach pyun added potato starch. Peach pyun added 0% pectin was more preferable than peach pyun with 1% pectin. As a result of texture analysis, the texture of peach pyun added mungbean starch was denser than that added potato starch. Adding 1% pectin to peach pyun increased mechanical properties such as hardness and chewiness. Mungbean starch pyun with pectin on lightness, Potato starch pyun with pectin on redness, and potato starch pyun with pectin on yellowness were significant(p<0.01). Lightness has a tendency to decrease with increasing sugar density. Adding 1% pectin has the effect to increase lightness, redness and yellowness. The subject parameters that effect overall quality on sensory evaluation were found taste quality, texture quality, hardness, adhesiveness and taste by using regression analysis.
