포도 갈색무늬병균의 침입부위를 알고자 잎의 앞면과 뒷면에 병원균을 접종한 결과 포도 잎의 앞면에 병원균을 접종한 처리구는 전혀 침입이 없었으며, 같은 잎의 뒷면에 병원균을 접종한 모든 처리구에서는 접종 15일 후에, 접종 지점 수와 동일한 수의 병반이 형성되었다. 병원균 접종 후에 발병에 소요되는 기간을 조사한 결과, 포도 잎의 뒷면에 접종한 경우, 접종 8일 후부터 병반이 나타나기 시작하여, 접종 10일 후에는 거의 모든 접종 지점에 병반이 나타났다. 갈색무늬병에 감수성인 캠벨얼리 품종에서는 잎 뒷면에 부착한 분생포자가 발아하여, 기공을 통하여 직접 식물체 조직 속으로 쉽게 침입하는 것을 관찰할 수 있었다. 반면에 저항성인 거봉 품종에서는 분생포자가 기공 근처에서 발아하였어도 기공을 쉽게 인식하여 찾아가지 못하거나, 기공을 찾아도 침입을 하지 못하고 기공을 넘어서 계속 발아하기도 하였다. 또한 발아관이 기공에 도달하는 도중에 기공 주변을 감싸기도 하고 공변세포에 이르러서도 쉽게 기공을 통해 조직 속으로 침입하지 못하였다. 심지어 어렵게 기공을 인식하여 침입을 했어도 계속 발아하면서 감수성 품종과 달리 조직 속으로 침입하지 않고 다시 기공 밖으로 나오는 모습이 관찰되기도 하였다. 갈색무늬병에 감수성 품종과 저항성 품종에서의 단위면적당 기공 수를 조사한 결과, 감수성 품종인 캠벨얼리 품종이 저항성 품종인 거봉의 기공 수보다 많았고, 그 크기는 거봉 품종이 컸다. 따라서 갈색무늬병균은 단위면적당 기공 수의 다소가 침입을 좌우하고, 그 크기에 의해 좌우되지는 않는 것으로 추정된다. 저항성인 거봉 품종의 기공은 전체적으로 식물체의 표면과 기공을 구성하는 공변세포와의 높이 차이가 거의 없었던 것이 형태적으로 명확하게 관찰되는 반면, 감수성인 캠벨얼리 품종의 기공은 전체적으로 식물체의 표면과 기공을 구성하는 공변세포와의 높이 차이가 현저한 것을 주사전자현미경과 광학현미경을 이용하여 명확하게 관찰하였다.

개다래(Actinidia polyama Max.)는 복통, 류마티스 관절염, 뇌졸중 치료에 사용되었으며, 최근 소염, 진통, 통풍에 효과가 있다고 알려져 있으나 특유의 강한 향과 맛을 지니고 있어 기능성 식품이나 치료용 약물을 개발하고자 할 때 많은 제약이 따른다. 따라서 개다래를 초임계 추출하여 향과 맛을 개선하고, 본 연구에서는 초임계추출 후 남은 부산물을 이용하여 (박)추출물을 제조하고 항염증 및 항동맥경화 활성을 조사하였다. 개다래 주정 추출물 및 초임계 박 추출물의 NO 소거활성을 비교한 결과, 개다래박 11 추출물 10, $100\;{\mu}g/mL$의 농도에서 36.63, 79.58%의 NO 소거활성을 보여 주정 추출물(4.61, 19.00%)에 비해 훨씬 높은 NO 소거활성을 보였다. 또한 RAW 264.7 세포주에 개다래 초임계 박 11 추출물을 처리하고, LPS를 처리하여 염증을 유발한 후 염증인자인 $PGE_2$의 생성, 그리고 proinflammatory cytokines인 TNF-$\alpha$의 생성량을 측정한 결과, 개다래 박 11 추출물은 LPS로 유도된 염증 인자들을 효과적으로 감소시키는 것으로 나타났다. 또한 박 11 추출물의 MMP-9 활성에 미치는 영향을 알아보기 위해 zymography를 실시한 결과, 추출물 50, $100\;{\mu}g/mL$의 농도에서 MMP-9의 활성이 효과적으로 감소됨을 확인하였으며, MMP-9의 단백질 발현도 억제됨을 확인하였다. 결론적으로 개다래 박 11 추출물은 LPS로 유도된 염증 인자들을 효과적으로 감소시켰으며, TNF-$\alpha$에 의해 증가된 MMP-9의 활성을 억제하는 것으로 나타나 동맥경화를 비롯한 고혈압, 암, 당뇨, 관절염 등의 만성염증성 질환의 예방과 치료에 효과적으로 적용할 수 있을 것으로 생각된다.

농업분야에서의 IT역할에 대한 요약과 함께, 일본의 경험을 살펴보는 한편 당면 현안의 파악, 그리고 정보기술 활용의 성공사례를 들어 문제해결 방안의 하나로 신기술을 소개하였다. IT 활용능력 여부는 성공적인 IT현장활용의 매우 중요한 요소로,. IT 관련 교육/훈련의 강화 외에, 사용이 용이한 인터페이스 여하는 IT활용력 제고의 커다란 도전이기도 하다. 기존의 자판형 PC 인터페이스는 대다수 농민들이 쉽게 받아들이기 어려운 면이 있는 것이 분명하다. 이러한 최종사용자들에게 사용이 보다 쉬운 컴퓨터시스템을 제공하기 위한 여러 가지 기술들이 현재 개발되어 있다. 예를 들어 휴대폰기반의 사용자 인터페이스는 이러한 문제에 대한 해결책의 하나로 매우 유망한 기술임에 틀림없다. 휴대폰 사용은 개도국에서도 점차 확대되고 있으며, 단 몇 개의 키만으로 쉽게 사용할 수 있는 장점이 있다. 농민들은 복잡한 의사결정지원을 필요로 하지 않기 때문에 휴대폰의 이러한 단순한 화면도 대개 충분한 기능을 구현할 수 있는 것이다. 제2, 3세대 휴대폰은 인터넷에 대한 무결성 접속을 제공하므로, 휴대폰인터페이스에 적합한 활용물을 개발한다면 기존 PC의 역할을 대신할 수도 있을 것이다. 실지로 현재 휴대폰은 자료수집 뿐만 아니라 포장에서의 현장 의사결정지원에 사용되고 있다. 예를 들어 로렌슨 등과 사사끼 등은 휴대폰기반 기상정보취득프로그램을 개발하여 농민이 항상 자신의 포장내 기상상태를 파악할 수 있게 되었다. 병충해예찰시스템과 같은 보다 실용적인 응용 프로그램도 이미 초기모형이 개발되어 있다. PC보다 사용이 용이한 인터페이스와 포장에서의 기동성 등이 농민들에 의해 환영받고 있는 점이다. 또 다른 중요한 문제는 농촌의 미진한 네트워크 하부구조에 기인한다. 불행히도 농촌지역에서는 상업통신업자간 치열한 경쟁을 기대할 수 없기 때문에 이 문제는 결국 정부의 책임일 수 밖에 없다. 거대한 산맥에서 금을 채굴하는 것과 유사한 정보탐색이라는 기술도 매우 중요한 요소이다. 근대농업이 시작된 이래 약 한세기에 걸친 농업 생산과 실험연구의 결과, 일본은 방대한 농업자료를 보유하고 있다 이러한 장기자료는 농업생산에서의 신지식을 생산제공하는 데 필수적인 결정적인 정보원일지 모른다. 정보탐색 기술은 이러한 방대한 자료의 분석을 통한 미지의 사실을 추론하는 유망한 기술로 이용될 것이다. 많은 이들이 IT기술에 의해 농업이 힘을 얻기를 기대하고 있다. 그러나 어떠한 실용적인 IT 대응책이 농업을 강화할 수 있느냐는 질문에 대한 답변에는 궁색할 수밖에 없다. 이는 이러한 질문에 대한 보편적인 해답이 없기 때문이다. 농업은 전형적으로 기후와 토양조건, 작부양식, 시장요구도 등에 좌우되는 지역 특이적 특성을 지닌다. 그러므로 이는 개별 여건에 알맞는 유연한 기술 적용 여부를 결정하는 IT활용시 의사 결정자을 하는 사람의 몫이 될 것이다.

The purpose of this study was to conduct a survey on the senses that preliminary dental hygienists have on employment, who applied for the National Dental Hygienist Examination, so that it could provide a basic reference required for fostering good human resources specializing in oral health with a sense of mission and responsibility as professional. To meet these goals, a self-administered questionnaire survey was conducted for participants in a refresher education meeting for preliminary dental hygienists across three major regions(Seoul, Daejeon and Busan), which was held by the Korean Dental Hygienists Association(KDHA) on Jan. 15, 2006. Total 289 sheets of questionnaire were collected, and 262 sheets except invalid or incomplete ones were used for examination and analysis. As a result, this study came to the following conclusions: First, it was found that 40.4% respondents wanted to be employed in dental clinic or hospital. Most respondents(90.1%) answered that faithfulness is most valued as prerequisite qualification for employment in hospital, and highest percentage of respondents(39.3%) wanted to earn 16 to 17 million Korean won annually. For internship opportunities, 61.9% respondents replied that they could willingly accept the internship, provided that basic pay and switchover to regular employee are all assured. Second, as the results of survey on employment circumstances around respondents, it was found that most respondents(58.3%) were employed in dental clinic or hospital, and highest percentage of respondents(35.0%) earned 15 to 16 million Korean won. Third, it was found that interpersonal relationships among employees had most significant effects(4.81) on selection of employment, which was followed by in-house welfare benefits 1(monthly/annual vacation, resting room, etc; 4.56). For possible influential factors on the selection of employment depending on whether employed or not, it was found that there were Significant differences in pay, welfare benefit 2(seminar, orientation, refresher training opportunities, etc), post-wedding continued employment and merit system between employees and non-employees(pE0.05). Fourth, the survey on respondents' occupational senses of dental hygienist showed that major tasks of dental hygienists were represented by oral disease prevention(92.6%), case management(71.5%), oral health education(66.3%), hospital/clinic management and dental management support(10.4%) and public oral health activities(6.7%) respectively. For job satisfaction, it was found that almost half respondents(48.9%) showed satisfaction at their job and 32.6% felt satisfied at and proud of their job. That is, majority of respondents(81.5%) felt satisfied at their job as dental hygienist. For follow-up requirements to qualify for dental hygienists, it was found that 73.3% felt it necessary to give more investments to self-development, 62.2% respondents considered protection of membership's rights as one of future assignments that KDHA should be more committed to. For future social awareness about dental hygienists as occupation, 69.2% respondents expected that they would be better developed and treated as professional. And desired training courses as a part of qualification for professional dental hygienists were represented by case management(services, manners, etc; 33.3%), implant(28.9%), esthetics(correction, prosthesis, whitening; 18.9%) and so on. For an item on working years, it was noted that 75.9% respondents would keep working as dental hygienists as long as they could.

The objects of this study are to find out (1) real situation of the food supply in prison under Imperial Government of Japan more cleary (historical meaning) and (2) which might help in understanding wrong present food consumption patterns in Korea which causes environmental as well as health problems. It is generally known that the length of the Japanese occupation for Korea is 36 years. However, it is concluded in this study that it was longer (70 years ; from 1875 to 1945 from when Japanese Army attacked and occupied Yungjongdo and Kanghwado island to e time when they were defeated on World War II.) Korea was annexed by Japan in 1910 then the Imperial Government of Japan dismissed the Korea Army, controlled the Office of Justice and the management of prison by force. Since then about 50% of all land was fell into Japanese Government ownership and 80% of Korean farmers became as tenant. After this change, Korea farmers were forced to pay extremely high rent (up to 80% of its harvest). Forced immigration, low price procurement of grain by Japanese government up to more than 30%of their production, was practiced. Accordingly, the food situation of Korean farmers became miserable, which may caused more violations of Imperial Japanese Law. Malnutrition, epidemic diseases, mortality rate of infants soared and average life expectancy shortened to 20-30 years old. This was the period of World Economic Crises and Food Crises in Japan. It was said then that if one Japanese comes to Korea then 200 Koreans will starved to death. Meanwhile, Proconsul Bureau of Chosun requested to the Department of Medicine, the Imperial University of Kyungsung to survey food supply situation of Koreans in prison throughout Korea. Objectives of the survey then was not only to find out scientifically whether it is agreeable in maintaining prisoner's health and also find out the possibility to save food during food crisis. Survey was started from 1923 and ended in 1945, and it focussed on prisoners in the Seodaemoon Prison. This report is the outcome of the first survey. They concluded that the food supplied was nutritionally (had) no problem, in compare with those of workers in the factory, students in the dormitory in Japan and with those of prisoners in Taiwan, France and Germany. Amount of grain supplied were different according to their work lord and was divided into 9 different levels. Total grain was consisted of 50% millet, 30% soybean and 20% indica rice(variety). However, there were no difference in the amount of supply of side dishes between work groups. For the highest working group, 3280g of boiled grain per day was supplied to make stomach full but as a side dishes, salty fermented bean paste, fermented fish and salty soups, etc. was supplied. Deficiency of animal protein were observed, however, high intake of soybean may possibly caused animal protein deficiency problem. On the contrary, the intake of water soluble vitamins were insufficient but the level of calcium and iron intake seems to be sufficient, however, imbalance of intake of nutrition may caused low absorbtion rate which might caused malnutrition. High intake of dietary fiber and low intake of cholesterol may possibly prohibited them from so called modem disease but may caused the defect in disease resistancy againist epidemics and other traditional disease. Over intake of salt(20-30g per day) was observed. Surveyors who attended in this survey, mentioned that the amount of food intake may nutritionally be sufficient enough but the quality of food(and possibly, the taste of food) were like that of animal feed. For the officials who received this report might consider that considering the war situation and food crisis, the supply situation of food in the prison may considered to be good enough(because they are not starving). But as a Korean who studied this report, one feel extremely pity about those situation because (situation of) those period were very harsh under the Imperial Law and keeping the Law by Koreans were almost impossible, therefore, about one third adult violated the Law and were put into jail. And they were treated like animals.

This study was designed to establish working range for reoportable range in own laboratory in order to cover the upper and lower limits of the range in test method. We experimented ten times during 10 days for setting of reportable range with between run for method evaluation. It is generally assumed that the analytical method produces a linear response and that the test results between those upper and lower limits are then reportable. CLIA recommends that laboratories verify the reportable range of all moderate and high complexity tests. The Clinical Laboratory Improvement Amendments(CLIA) and Laboratory Accreditation Program of the Korean Society for Laboratory Medicine states reportable range is only required for "modified" moderately complex tests. Linearity requirements have been eliminated from the CLIA regulations and from others accreditation agencies, many inspectors continue to feel that linearity studies are a part of good lab practice and should be encouraged. It is important to assess the useful reportable range of a laboratory method, i.e., the lowest and highest test results that are reliable and can be reported. Manufacturers make claims for the reportable range of their methods by stating the upper and lower limits of the range. Instrument manufacturers state an operating range and a reportable range. The commercial linearity material can be used to verify this range, if it adequately covers the stated linear interval. CLIA requirements for quality control, must demonstrate that, prior to reporting patient test results, it can obtain the performance specifications for accuracy, precision, and reportable range of patient test results, comparable to those established by the manufacturer. If applicable, the laboratory must also verify the reportable range of patient test results. The reportable range of patient test results is the range of test result values over which the laboratory can establish or verify the accuracy of the instrument, kit or test system measurement response. We need to define the usable reportable range of the method so that the experiments can be properly planned and valid data can be collected. The reportable range is usually defined as the range where the analytical response of the method is linear with respect to the concentration of the analyte being measured. In conclusion, experimental results on reportable range using concentrated control sample and zero calibrators covering from highest to lowest range were salicylate $8.8{\mu}g/dL$, phenytoin $0.67{\mu}g/dL$, phenobarbital $1.53{\mu}g/dL$, primidone $0.16{\mu}g/dL$, theophylline $0.2{\mu}g/dL$, vancomycine $1.3{\mu}g/dL$, valproic acid $3.2{\mu}g/dL$, digitoxin 0.17ng/dL, carbamazepine $0.36{\mu}g/dL$ and acetaminophen $0.7{\mu}g/dL$ at minimum level and salicylate $969.9{\mu}g/dL$, phenytoin $38.1{\mu}g/dL$, phenobarbital $60.4{\mu}g/dL$, primidone $24.57{\mu}g/dL$, theophylline $39.2{\mu}g/dL$, vancomycine $83.65{\mu}g/dL$, valproic acid $147.96{\mu}g/dL$, digitoxin 5.04ng/dL, carbamazepine $19.76{\mu}g/dL$, acetaminophen $300.92{\mu}g/dL$ at maximum level.

This study was conducted to patients visited oral maxillo-facial surgery, KNUH and the purpose of the study was to assess skeletal and dento-alveolar stability after surgical-orthodontic correction treated by skeletal Class III malocclusion patients with open bite versus non-open bite. This retrospective study was based on the examination of 40 patient, 19 males and 21 females, with a mean age 22.3 years. The patients were divided into two groups based on open bite and non-open bite skeletal Class III malocclusion patients. The cephalometric records of 40 skeletal Class III malocclusion patients (open bite: n = 18, non-open bite: n = 22) were examined at different time point, i.e. before surgery(T1), immediately after surgery(T2), one year after surgery(T3). Bilateral sagittal split ramus osteotomy was performed in 40 patients. Rigid internal fixation was standard method used in all patient. Through analysis and evaluation of the cephalometric records, we were able to achieve following results of post-surgical stability and relapse. 1. There was no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in maxillary occlusal plane angle of pre-operative stage(p>0.05). 2. Mean vertical relapses of skeletal Class III malocclusion patients with open bite were $0.02{\pm}1.43mm$ at B point and $0.42{\pm}1.56mm$ at Pogonion point. In skeletal Class III malocclusion patients with non-open bite, $0.12{\pm}1.55mm$ at B point and $0.08{\pm}1.57mm$ at Pogonion point. There was no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in vertical relapse(p>0.05). 3. Mean horizontal relapses of skeletal Class III malocclusion patients with open bite were $1.22{\pm}2.21mm$ at B point and $0.74{\pm}2.25mm$ at Pogonion point. In skeletal Class III malocclusion patients with non-open bite, $0.92{\pm}1.81mm$ at B point and $0.83{\pm}2.11mm$ at Pogonion point. There was no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in horizontal relapse(p>0.05). 4. There were no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in post-surgical mandibular stability(p>0.05). and we believe this is due to minimized mandibular condylar positional change using mandibular condylar positioning system and also rigid fixation using miniplate 5. Although there was no significant relapse tendency observed at chin points, according to the Pearson correlation analysis, the mandibular relapse was influenced by the amount of vertical and horizontal movement of mandibular set-back(p=0.05, r>0.304).

The Korean Association of Pediatric Surgeons (KAPS) performed the second nationwide survey on biliary atresia in 2011. It was a follow-up study to the first survey, which was performed in 2001 for the retrospective analysis of biliary atresia between 1980 and 2000. In the second survey, the authors reviewed and analyzed the clinical data of patients who were treated for biliary atresia by the members of KAPS from 2001 to 2010. A total of 459 patients were registered. Among them, 435 patients primarily underwent the Kasai operation. The mean age of patients who underwent the Kasai operation was $66.2{\pm}28.7$ days, and 89.7% of those patients had type III biliary atresia. Only five patients (1.4%) had complications related to the Kasai operation. After the Kasai operation, 269 (61.8%) of the patients were re-admitted because of cholangitis (79.9%) and varices (20.4%). One hundred and fifty-nine (36.6%) of the patients who underwent the Kasai operation subsequently underwent liver transplantation. The most common cause of subsequent liver transplantation was persistent hyperbilirubinemia. The mean interval between the Kasai operation and liver transplantation was $1.1{\pm}1.3$ years. Overall the 10-year survival rate after the Kasai operation was 92.9% and the 10-year native liver survival rate was 59.8%. We had 23 patients for primary liver transplantation without the Kasai operation. The mean age patients who underwent primary liver transplantation was $8.6{\pm}2.9$ months. In summary, among the 458 Kasai-operation and liver-transplantation patients, 373 lived, 31 died, and 54 were unavailable for follow up. One-third of the patient who survived have had complications correlated with biliary atresia. In comparison with the first survey, this study showed a higher survival rate and a greater number of liver transplantation.

본 연구는 실험동물 대상으로 하는 두 가지 구강안면통증모델을 이용하여 산자나무 추출물 H. rhamnoides (sea buckthorn)의 통증조절효과를 확인하고자 하였다. 5% formalin을 실험동물 안면부 피하($50{\mu}l$) 또는 측두하악관절($30{\mu}l$) 내로 주입하여 안면부를 긁거나 문지르는 통증행위반응을 유도하였다. Formalin의 주입으로 인한 안면부통증행위반응은 15분 이후부터 증가하여 25, 30분에 가장 높게 나타났으며 40분까지 지속되다가 45분에 감소되었다. 안면부 통증 유발 30분 전 150 mg, 300 mg/kg (1 ml)의 농도로 산자나무 추출물을 희석하여 경구투여하였다. DW를 경구투여한 대조군에서는 formalin에 의한 통증행위반응의 변화에 영향을 미치지 않았으나 산자나무 추출물(150, 300 mg/kg)의 경구투여는 각 $305.3{\pm}20.7$회, $137.3{\pm}21.8$회로 포르말린으로 유도된 안면부통증행위반응을 감소시켰다. 시간에 따른 변화의 결과로, 산자나무 추출물의 300 mg/kg 경구투여는 25~40분에서 formalin에 의해 증가된 안면부통증행위반응을 현저하게 감소시켰다. 측두하악관절에 주입한 포르말린은 $306.8{\pm}31.4$회의 통증행위반응을 나타내어 턱관절 통증을 유도하였고, 산자나무 추출물(150, 300 mg/kg)의 경구투여는 턱관절통증행위반응을 각 $184.7{\pm}20.0$회, $125.7{\pm}9.8$회로 감소시켰다. 시간의 경과에 따라 결과에서 산자나무 추출물의 경구투여는 포르말린 주입 30분에서 유의한 턱관절 통증경감효과를 나타냈다. 따라서, 본 연구의 결과는 산자나무 추출물의 구강안면 통증조절에 대한 예방적 또는 치료적 제제로의 활용가능성에 대한 기초자료로 활용가능할 것으로 생각된다.
