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.

Cha, Jae Yoon,Cho, Yong-Jin,Kim, Chong-Tai,Kim, Chul-Jin,Ng, P. K. W. 한국산업식품공학회 2003 산업 식품공학 Vol.7 No.2

The purpose of this study was to develop extrusion process of fresh potato and to study the effects of extrusion condition on the pasting properties of extruded potato products. The blend of pressed potato and wheat flour and pressed potatoes were extruded at different die exit temperatures (110-160℃) and screw speed of 100 rpm using a twin-screw extruder with conveying, high and low shear screw configuration. The viscosity-related parameters, such as peak viscosity, through, final viscosity, peak time, and pasting temperature of the feed materials and extruded products, were studied using a rapid visco analyzer (RVA). Their water solubility index (WSI) and water absorption index (WAI) were also studied. The peak viscosity, through, final viscosity, and peak time of pressed potato extrudates and potato-wheat flour mixture extrudates decreased as die exit temperature increased. The WSI and WAI of potato products increased as die exit temperature increased. When high shear screw configuration was used, the values of viscosity-related parameters were lower than those when low shear screw configuration was used. The potato-wheat flour mixture products obtained different degrees of depolymerization from fresh potatoes and wheat flour depending on die exit temperature and screw configuration.

조상과 후손의 만남에 대한 동서양 다원적 패러다임 연구 -주자의 감응이론과 칼융의 동시성이론을 중심으로-

박재갑 ( Jae-gahb Park ),고재석 ( Jae-suk Go ),전철 ( Chul Chun ) 충남대학교 유학연구소 2016 儒學硏究 Vol.34 No.-

우리 주위에서 인과관계를 알지 못하는 현상들을 드물지 않게 접한다. 이러한 현상들은 사실이 아니라고 보기보다는 어떠한 중요한 사실을 아직 알지 못하였기 때문에 이해가 안 되는 것이 아닌지 반문하게 한다. 이 글에서 근거로 삼은 자료는 논문의 공동필자인 박재갑 교수 집안에서 일어난 두 가지 사건이다. 첫째는 박재갑 교수의 15대 조상으로 1545년에 돌아가신 필재 박광우의 시신을 이장하는 날 밤, 사촌 형인 박재학의 꿈에 필재 할아버지가 나타나 자신이 소장하였던 방울을 찾아오라는 말을 듣고, 이후 파주에 가서 방울을 소장하고 있던 사람에게 방울을 찾아온 사건이다. 둘째는 박재갑 교수의 부친이 돌아가신 날 이모의 출가한 딸 꿈에 박재갑 교수의 부친이 금시계를 가지고 나타나신 꿈을 꾸었다. 이모의 딸은 이모부가 돌아가신 줄도 모르고 있었고 더욱이 이모부의 아들 부부가 금시계를 사갖고 온 것을 알 수가 없었는데, 금시계와 관련된 꿈을 꾼 일련의 사건이다. 과학을 주류 패러다임으로 삼고 있는 현대문명에서 보면, 신비롭고 기이한 현상은 그저우리가 확인하지 못하는 일상이나 정신현상의 일부일 수도 있다. 그런데 주자(朱熹,1130~1200)의 감응이론과 칼 구스타프 융(Carl Gustav Jung, 1875~1961)의 동시성이론은 인과관계를 알 수 없는 현상들에 대해 각기 다른 해석을 내놓는다. 인과관계를 알 수 없는 현상은 제한적 합리성의 완고한 세계관 자체가 균열되는 사건이며, 동시에 우리의 삶이 이해의 영역을 넘어선 광대한 현실에서 펼쳐지는 사건임을 말해준다. 실로 미지의 우주, 그리고 삶과 죽음에 대한 다원적 패러다임의 폭넓은 수용과 진지한 대화가 더 요청되는 시대이다. 이러한 관점에서 본 연구에서는 조상과 후손의 만남, 감응, 현현의 사례를 성리학의 감응이론과 칼 구스타프 융의 동시성이론의 관점에서 조명하고자 한다. We frequently witness phenomena which occur around us, not revealing the causal relationship. We can ask ourselves whether such phenomena are hard to understand not because they are not true facts but because they are beyond our understanding. The reference data for such a phenomenon in this article are the two events that had occurred in the family of Professor Jae-Gahb Park, one of the co-authors of this article. Firstly, on the eve of the night when his fifteenth-generation ancestor’s grave was to be moved, his ancestor appeared in his consin’s dream, telling him to go and find the bell that his ancestor had cherished. Accordingly, his father and relatives went to Paju county, where his ancestor’s grave is located, to remove the grave to another place. In the process, his father told the participants what his consin had dreamt of including a grave keeper who had kept the bell after reburial. The grave keeper returned it to his father after hearing from him. Secondly, On the day when Professor Park’s father died, his father appeared in the dream of his maternal aunt’s married daughter, carrying a gold watch with him. She was not aware that Professor Park’s father was dead. Furthermore, Neither did she know that Professor Park‘s old brother and his wife in America had bought the gold watch for his father. These two cases are representative examples of ancestors’ revelation through dream. According to the modern civilization which regards sciences as its mainstream paradigm, such mystical and arcane phenomena are just a part of mental phenomena that we cannot verify with our knowledge. However, there are two scholars presenting different explanations about the phenomena of which the causal relationship is not understood yet: Carl Gustav Jung (1875~1961)’s phenomenon of synchronicity and Zhu Xi (朱熹, 1130~1200)’s theory of correlation. A phenomenon whose causal relationship is not understood yet is an event in which the obstinate outlook of the restrictive rationality breaks off, and at the same time our life spreads into the vast realm transcending our understanding. We are living in an era when more discussions on the unknown universe and pluralistic paradigms on the questions about life and death need to be made. In this regard, Gustav Jung’s concept of Synchronicity and Neo-Confucian theory of correlation is instrumental in overcoming the phenomenon and case in which the causality breaks off.

백금과 세리아를 담지한 촉매의 포름알데히드 산화반응에 관한 연구

김영철,김재승,박남국,김재관,신재순 全南大學校 觸媒硏究所 1996 觸媒硏究 論文集 Vol.18 No.-

Total oxidation of formaldehyde was studied using platinum and platinum-ceria catalysts supported on γ- alumina. Catalysts were prepared by coimpregnation with γ- Al₂O₃, Platinum and ceria loading were controlled as 0.02∼0.04wt% and 0.3∼7.6wt%, respectively. The characterization of the catalysts were investigated by catalytic activity, O₂-TPD and H₂-TPR. The order of catalytic activities in view of formaldehyde conversion was as follows ; Pt+Ce(0.3%)/Al₂O₃>Pt+Ce(0.8%)/Al₂O₃>Pt+Ce(5%)/Al₂O₃>Pt+Ce(7.6%)/Al₂O₃>Pt/Al₂O₃. Small amount of added ceria enhanced the catalytic activity. However, as the amount of ceria increased the activity was decreased. Optimum loading of ceria seems to be 0.3∼0.8w%.

It has been studied the system and the classification for the narrative which selects and puts in on record in the Orient, in this manuscript before it is investigated the classification, the evolution and the purport of the political narrative from Confucian point of view. It was the thought of the oriental Confucian literature of the Orient that literature must take on the way. It is called Jae-do-jee-gi(載道之器). Until the Western theory of literature was introduced in the Orient, this was the firm theory which had never taken a challenge before. So that these included the subject of the narrative recording. It just excluded narrative which was not worth a plugged nicked or did not exist bosasung(補史性). Even if the narrative was given in a dictionary, the fact would have reported the matter to an emperor, moreover it would have broadly given currency to the people. Repeatedly the narrative which was not worth a plugged nicked when they had reported the matter to kings of many previous generations or the people were not enlightened would be excepted the subject of recording. By the way, in the Orient, there was specially a narrative recording management with the Confucian political object of publishing the union of church and state from the quite early season. According to historical record it was Ju-in(?人), a passersby, a Chai-si diadem, a Pagoan, a narration extra, an opinion book, a narration of an opinion book, a man of an opinion book, a narration, a novelist and so on. This manuscript set up some system of the evolution theory though the record related to them in the variety of literature. Namely it was switched a Chai-si diadem to a Pagoan, a Pagoan to a narration, a narration to a novelist. On the other hand, on the authority of the canon of classification of the Book of Song's poetry, this manuscript tried out classification of a political narrative in conclusion. The classification was as follows. 1) The genre story of the rise and decline (1) The genre story of prosperity(the story of justice style) ① Good government story ② Morality story (2) The genre story of decline (the story of anti-justice style) ① The misgovernment story ② Unmorality story 2) The genre story of good advice From now on the present writer will continually write an regular thesis on the political story of Korean based on the thesis above.

Quantitative comparison of mRNA expression of glucosyltransferase(GTF) between xylitol-resistant(X^(R)) and xylitol-sensitive(X^(s)) mutans streptococci

Kim, Chong-Chul,Lee, Mi-Na,Kim, Young-Jae,Lee, Sung-Hoon 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.1

Since the long-term exposure of mutans streptococci to xylitol is known to select for xylitol-resistant(X^(R)) natural mutants, the occurrence and survival of such X^(R) strains were performed in batch culture methods. The aim of the study was to compare the differentiation and quantification of mRNA expression of the gtf genes of X^(R) and X^(S) mutans streptococci. Using a real-time reverse-transcription polymerase chain reaction, the expression of each gtf was determined. In X^(R) strains, the relative levels of transcription of gtfB and gtfC were decreased while that of gtfD was increased, suggesting the presence of independent promoters. It also suggested that mutation related to production of glucosyltransferase occurred under the exposure of xylitol could explain the caries-preventive mechanisms of xylitol. 자일리톨에 장기간 노출된 mutans streptococci는 자일리톨에 내성이 발현되어 자일리톨 내성균주가 생성된다고 알려져 있다. 본 연구의 목적은 mutans streptococci에서 자일리톨 내성균주와 감성균주의 gtf 유전자 발현량을 각각의 유전자별로 정량적으로 분석하고 비교하는 것이다. 실시간 역전사 중합효소연쇄반응법을 이용하여 각각의 gtf 발현을 조사한 결과 gtfD는 증가한 반면. gtfB와 gtfC는 감소하였는데 이는 각 유전자의 독립된 조절기전이 존재함을 보여주는 것이다. 또한 자일리톨에 노출된 mutans streptococci에서의 glucosyltransferase와 연관된 유전자변형이 자일리톨의 치아우식증 예방효과의 작용기전 중 하나임을 알 수 있었다.

김송이,최성철,최영철,김광철,박재홍 大韓小兒齒科學會 2010 大韓小兒齒科學會誌 Vol.37 No.3

자이오머(Giomer)는 레진강화형글라스아이오노머에 견줄 만큼 불소방출량이 많다고 하나, 우식예방 효과에 관한 연구들이 많지 않아 임상적용에 대한 근거가 부족한 실정이다. 본 연구는 자이오머(BF 군)를 포함하여 레진강화형글라스아이오노머(FF 군), 콤포머(DA 군)와 대조군인 콤포짓(FZ 군)의 우식억제 효과와 주변 치질로의 불소침투 양상을 비교하기 위하여, 공초점레이저주사현미경과 전자탐침미세분석기를 이용하여 각 수복재의 우식예방 효과를 비교하였으며, 다음과 같은 결과를 얻었다. 1. 수복물 주위 이차 인공우식에서 법랑질 외측병변의 깊이는 FZ 군에서 가장 깊었으며, BF 군이 가장 작게 나타났다(p<0.05). 2. 수복물과 법랑질 계면에 나타난 탈회억제층의 두께를 관찰한 결과 FZ 군이 가장 작게 나타났으며, FF, DA, BF 간에는 유의성 있는 차이를 보이지 않았다(p<0.05). 3. 법랑질에 침투된 불소농도는 BF, FF, DA의 순으로 높게 나타났다. 4. 상아질에 침투된 불소농도는 DA, BF, FF의 순으로 높게 나타났으며, 이는 상아질-수복물의 접착 계면에 영향 받는 것으로 보인다. The purpose of this study was to evaluate the effect of light cured fluoride-releasing materials on the inhibition of demineralization. In addition, the pattern of fluoride uptake of adjacent tooth structure was analyzed with EPMA. Eighty intact premolars were restored with Filtek Z250(control group, composite), Fuji Filling LC(RMGI), Dyract AP (compomer) and Beautifil II(giomer). Restored teeth were stored in distilled water for 30 days. Thensixty teeth(n=15) were exposed to demineralizing solution(pH 4.3). Demineralized teeth were bisected and polished. The specimens were observed with confocal laser scanning microscope. The depth of outer lesion and the thickness of inhibition zone were measured. Remained twenty teeth(n=5) were bisected for fluoride uptake analysis. The fluoride analysis were taken at enamel-restoration interface and dentin-restoration interface by electron probe micro-analyzer. The results are as follows: 1. The depth of outer lesion of Fuji Filling LC, Dyract AP, Beautifil II was shallower than that of Filtek Z250 at the margin of restoration(p<0.05). 2. The thickness of caries inhibition zone of Fuji Filling LC, Dyract AP, Beautifil II was greater than that of Filtek Z250 at the margin of restoration(p<0.05). 3. Fuji Filling LC, Dyract AP, Beautifil II groups showed the greater fluoride uptake into enamel and dentine around restoration than Filtek Z250 group. 4. In dentin the difference of fluoride concentration were greater than in enamel, and Dyract AP showed the greatest fluoride concentration in dentin.

전치부의 경미한 공간부조화 개선을 위한 가철성 장치의 적용 예

곽아람,최영철,박재홍,최성철,김광철 大韓小兒齒科學會 2007 大韓小兒齒科學會誌 Vol.34 No.4

골격성 부조화가 없는 I급 부정교합은 치아-악궁 간의 크기 차이에 의한 총생(crowding)이나 공극(spacing)이 주된 문제점이다. 이와 같은 경미한 공간 부조화를 개선시키고자 할 때,치열의 종류,치아-악궁크기 부조화의 양,환자의 협조도,또는 환자의 요구 등에 따라 치료 방법은 다양할 수 있다. 본 증례보고에서는 I급 구치부 관계를 지니면서 전치부의 치아-악궁크기 부조화의 양이 크지 않은 영구치열에서 상하 악 전치부의 경미한 총생이나 공극이 관찰되는 경우에 사용할 수 있는 clear aligner와 spring aligner 장치의 이용에 관하여 보고하고자 한다. 이와 같은 장치들의 임상 적용에는 몇 가지 제한적인 조건이 있기는 하지만,잘 선택된 증례에서는 매우 유용하며 편리하게 이용될 수 있다. 특히 총생이 존재하는 경우에는 이를 해소시킬 공간이 치열 내에서 확보되어야 하므로,확실한 분석과 진단으로 치아 인접면 삭제의 양을 정확히 결정하여 각 치아들의 근심면과 원심면에서의 삭제의 양이 균등히 이루어질 수 있도록 하는 것이 바람직하다. 또한 치간에 공극이 존재하는 경우에는 배열 후 치열궁 둘레의 감소와 함께 상하악 전치부 간의 over-jet 문제가 생길 수 있어 대합치열과의 교합관계에 신중을 기하여야 한다. Class I malocclusion without skeletal problem results from tooth size/arch-size discrepancies, either evidenced by crowding, or spacing problems. Treatment method can be chosen according to dentition, the amount of arch discrepancy, patient compliance, or patient demands. We report of clear aligner and spring aligner that can be applicated in cases of permanent dentition with minimal arch discrepancy in anterior segment. There are some limits of application, but these are very useful appliances in the selective case. When crowding exists, definitive analysis and diagnosis should be made before starting treatment because certain amount of space must be obtained somewhere in the dentition to resolve the crowding. Therefore, appliance should be applied when lacking space is small. Also, in cases with spacing arch circumference is reduced after alignment so no problem in intermaxilla occlusal relationship must be confirmed. In case with crowding, judicious removal of interproximal enamel is indicated.

복합레진 적층계면에서 oxygen inhibition의 영향에 관한 연구

최수미,박재홍,최성철,김광철,최영철 大韓小兒齒科學會 2010 大韓小兒齒科學會誌 Vol.37 No.3

The purpose of this study was to assess the effect on oxygen inhibition layer(OIL) for the interfacial bonding between resin composite layers, including shear bond strength, fracture modes and degree of conversion. The first layer of specimen was filled with Z-250(shade A3) and was cured for 40s. The second layer of specimen was filled with same composite(shade A1) and was cured for 40s. The first layer of specimens for each group were prepared by methods as followings. Control(curing in atmospheric air), Group1(curing against Mylar strip), Group2(scrubbed with a acetonesoaked cotton), Group3(using Tescera light cup), Group4(using Tescera heat cup), Group5(stored in disti1led water for 30days at 37℃), Group6 (using bonding agent). The results were as follows: 1. There was no statistically significant different shear bond strength between control and group 1(p>0.05). 2. Group 2 showed significantly lower shear bond strength than control and group 1(p<0.05). 3. The observation of the fracture surface leads to the evidence that a major difference occurs in the case of control, group1 and group 3 samples which break mainly cohesively while the other groups break in majority adhesively. 4. The results of FTIR showed that the degree of conversion was the highest in group 2 and the lowest in control group(p<0.05). It can be concluded that an OIL is not necessary for bonding with composite resin. But if a reduced critical amount of the unreacted monomer is present, it was detrimental to bonding additional layers of composite. Further study, such as the quantitative analysis of the unreacted monomer are required. 복합레진의 적층계면에서 산소억제층(oxygen inhibition layer:이하 OIL)의 영향을 연구하기 위해, 아크릴릭 몰드(하층)에 복합레진의 shade A3를 충전한 후 표면의 조건을 달리하여 중합하였으며 상층은 shade A1으로 충전하고 중합하였다. 대조군(OIL 존재), 1군(OIL 형성억제), 2군(OIL 형성억제+레진표면의 미반응 모노머 제거), 3군(가압하에 중합), 4군(열중합), 5군(시효처리), 6군(시효처리+본딩제 도포)로 하층의 계면조건을 다르게 하였다. 전단결합강도와 파절양상, 전환률을 분석하여 다음의 결과를 얻었다. 1. 전단결합강도 측정 결과 대조군과 제 1군 사이에 통계학적으로 유의한 차이가 없었다(p>0.05). 2. 제 2군은 대조군과 1군에 비해 낮은 결합강도를 보였다(p<0.05). 3. 제 3군은 가장 높은 결합강도를 보인 반면, 4군은 가장 낮은 결합강도를 보였다. 4. 6군은 5군보다 두 배 정도 높은 결합강도를 보였다. 5. 대조군과 1군 및 3군에서는 주로 응집성 복합레진파절이 일어난 반면 2군, 4군, 5군과 6군에서는 주로 접착성 계면파절이 일어났다. 6. FTIR로 전환률을 측정한 결과 2군에서는 50.55%로 가장 높았고, 대조군에서는 가장 낮았다(p<0.05). 전단결합강도와 전환률의 결과로 보아, OIL은 복합레진 계면의 결합에 필수적인 요인은 아니며, 표층의 미반응 모노머가 결합강도에 영향을 미치는 것으로 보인다. 향후 계면 결합강도에 영향을 미칠 수 있는 미반응 모노머의 정량적인 분석을 통한 추가적인 연구가 필요할 것으로 생각된다.

구순구개열 환아에서의 치조골이식

조해성,박재홍,김광철,최성철,이긍호,최영철 대한소아치과학회 2007 大韓小兒齒科學會誌 Vol.34 No.1

치조파열 및 구개열과 같은 선천성 기형은 이환된 환자에게 기능적, 심미적으로 많은 문제점을 야기하므로 정상으로 회복시켜 주는 것은 중요한 문제이다. 장기간 방치될 경우 영양장애, 구강위생 불량, 호흡기 간염, 언어 장애, 악안면 변형, 그리고 정신적인 문제 등이 복합적으로 발생할 수 있다. 따라서 구순구개열 환자의 치료는 여러 전문 치료 분야의 복합적인 접근이 필요하다. 골이식은 구순구개열 환자에 있어 중요한 치과치료 단계이다. 치아의 맹출과 치열의 안정화를 위해 치열궁은 골격손이 없이 완전해져야 한다. 또한 치열궁의 파열이 있는 부위로는 정상적인 교정적 치아이동이 곤란하다. 따라서 구순구개열 환자에 있어 골이식은 광범위하게 적용되고 있는 외과적 술식이다. 치조골을 이식함으로써 치조열은 안정화되고, 견치 또는 절치가 이식부위로 이동할 수 있게 된다. 그리고 골 이식 후, 교정을 통해 치조열 부위의 공간을 폐쇄함으로써 보철 치료 없이 치열을 재형성할 수 있다. 골이식술에는 다양한 이식재료가 사용되었다. 자가골을 이식할 경우 장골이 가장 선호되며, 그 밖에 경골, 늑골, 두개골, 하악골을 이용하기도 한다. 그리고 골이식은 골이식 시기에 따라 일차골이식, 조기 이차골이식, 이차골이식, 만기 이차골이식으로 구분할 수 있다. 이차골이식은 혼합치열기 말경에 시행되는 것을 말하며 가장 좋은 것으로 받아들여지고 있다. 영구 견치가 맹출되기 전에 이차골이식을 시행하면 인접치아의 맹출과 보존에 도움이 된다. 본 증례에서는 치조구개파열 환자의 장골에서 골을 채취하여 골 이식을 시행한 후, 골이 채워진 이식 부위에 인접 치아가 성공적으로 이동하거나 치축이 개선되고 교정치료를 통해 치열궁 배열의 만족스러운 결과를 얻었기에 이를 보고하는 바이다 Cleft lip and palate are congenital craniofacial malformation. Reconstruction of dental arch in patient with alveolo-palatal clefts is very important, because they have many problems in functions and esthetics. Malnutrition, poor oral hygiene, respiratory infections, speech malfunctions, maxillofacial deformity, and psychological problems may be occured without proper treatment during the long period of management of the cleft lip and palate. So the treatment should be managed with a multidisciplinary approach. Bone grafting is a consequential step in the dental rehabilitation of the cleft lip and palate patient. A complete alveolar arch should be achieved of the teeth to erupt in and to form a stable dentition. And the presence of the cleft complicate the orthodontic treatment. Therefore bone grafting in patients with cleft lip and palate is a widely adopted surgical procedure. Grafted bone stabilizes the alveolar process and allows the canine or incisor to move into the graft site. After the bone grafting, orthodontic closure of the maxillary arch has become a common practice for achieving dental reconstruction without any prosthodontic treatment. Various grafting materials have been used in alveolar clefts. Iliac bone is most widely fovoured, but tibia, rib, cranial bone, mandible have also been used. And according to its time of occurrence, the bone graft may be divided into primary, early secondary, secondary, late secondary. Bone grafting is called secondary when performed later, at the end of the mixed dentition. It is the most accepted procedure and has become part of treatment of protocol. A secondary bone graft is performed preferably before the eruption of the permanent canine in order to provide adequate periodontal support for the eruption and preservation of the teeth adjacent to the cleft. In this report, we report here on a patient with unilateral cleft lip and palate, who underwent iliac bone graft. The cleft was fully obliterated by grafted bone in the region of the alveolar process. The presence of bone permitted physiologic tooth movement and the orthodontic movement of adjacent tooth into the former cleft area. Satisfactory arch alignment could be achieved in by subsequent orthodontic treatment.
