This study conducted a survey of the improvement and popularization for Korea Rice Cakes, a Korean traditional food, on two hundred women students in five colleges in Seoul, Korea. It was investigated to get the information of the recognition, preference, and consumption patterns for the succession and improvement of Korean Rice Cakes. The results are as follows: 1. A portion of 41.5% among responders knows from three to six kinds of Korean Rice Cakes, and of 28% can make at least one among the kinds of Korean Rice Cakes. 2. A portion of 91% recognizes that Korean Rice Cakes are one of well-nourished food, but of 42% answers that Korean Rice Cakes cannot be replaced with the principle food. Also, there are no significant differences in the recognition of Korean Rice Cakes as the kinds of religions. 3. The frequency of purchase is about one or twice in a month (35.5%). Consumers (36.5%) intend to purchase Korean Rice Cakes for the commemoration of national holidays or anniversaries. 4. The reasons for the preference of other foods more than Korean Rice Cakes are the easiness of purchase (36.0%), the deliciousness (21.5%), the diverse kindness (17.5%), and the proper package (9.5%). It is important that constant and particular school / home education is need to improve and success Korean Rice Cakes.

목적 : 기관지내시경 검사에서 흔히 사용되는 국소마취제인 lidocaine과 내시경시 지혈목적으로 사용되는 thrombin과 epinephrine이 각종 균주에 미치는 항균효과에 대해 알아보고자 하였다. 재료 및 방법 : 균주는 가톨릭대학교 성모병원에서 2004년 3월부터 2004년 9월까지 임상검체 에서 동정된 S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa 각각 42, 42, 42, 43주를 대상으로 하였다. Lidocaine, thrombin, epinephrine 감수성 검사는 National Committee for Clinical Laboratory Standards (NCCLS, 2002)의 기준에 따랐다. 결과 : Lidocaine은 S. aureus, S. pneumoniae, P. aeruginosa에서 MIC_(50), MIC_(90) 모두 20,000 ㎍/mL 이었다. K. pneumoniae는 각각 10,000 ㎍/mL이었다. Thrombin은 S. aureus와 P. aeruginosa에서 MIC50 500 lU/mL 과 MIC_(90) 500 IU/mL 이상이었고, K. pneumoniae에서는 MIC_(50)과 MIC_(90)이 모두 500 lU/mL이상이었으나 S. pneumoniae에서는 MIC_(50)과 MIC_(90)은 125 IU/mL이었다. Epinephrine은 K. pneumoniae, S. pneumoniae에 대한 MIC_(50), MIC_(90)가 모두 >500 ㎍/mL이었고, S. aureus와 P. aeruginosa에 대한 MIC_(50), MIC_(90)가 모두 500 ㎍/mL이었다. 결론 : 기관지 내시경 검사에서 흔히 쓰이는 lidocaine, thrombin, epinephrine 등의 약제들이 호흡기 질환의 흔한 병원균인 S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa 균주들에 대해 항균 효과가 있을 수 있어 세균배양검사에 영향을 미칠 수 있겠다. Background : We performed this stody to find out about antimicrobial effect of lidocaine which is commonly used local anesthetic, and thrombin and epinephrine used for hemostasis during bronchoscopic procedures. Materials and Methods : The microorganisms that were cultured from specimens obtained during bronchoscopy were Staphylococcus aureus (n=42), Streptococcus pneumoniae (n=42), Klebsiella pneumoniae (n=42), and Pseudomonas aeruginosa (n=43) collected from St. Mary's Hospital, from March to Sep 2004 were used for susceptibity testing. Susceptibility to lidocaine, thrombin, and epinephrine were tested according to the National Committee for Clinical Laboratory Standards. Result : MIC_(50) and MIC_(90) of lidocaine for S. aureus, S. pneumoniae, P. aeruginosa were all 20,000 ㎍/mL and that for K. pneumoniae were 10,000 ㎍/mL. MIC_(50) and MIC_(90) of thrombin for both S. aureus and P. aeruginosa was 500 IU/mL and above 500 IU/mL, respectively; that for K. pneumoniae were all above 500 IU/mL and for S. pneumoniae they were 125 IU/mL, MIC_(50) and MIC_(90) of epinephrine for K. pneumoniae and S. pneumoniae were above 500 ㎍/mL; that for S. aureus and P. aeruginosa were 500 ㎍/mL. Conclusion : We observed possible antimicrobial effect of lidocaine, thrombin, and epinephrine in vitro against pathogens such as S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa, which are common respiratory microorganisms. The use of these agants could affect the result of bacterial culture.

본 연구는 정하중하에서 최대하중과 변형을 이용하여 구한 변형강도(K_(D))로부터 아스팔트 콘크리트의 소성변형 계수의 추정 가능성을 보여준다. 이 논문은 새로운 강도특성치인 K_(D)를 개발하는 김테스트 연구의 일부로 최근 2, 3단계의 연구결과이다. 19mm 편마암과 화강암 2가지 골재와 3가지 폴리머로 제조한 7가지 바인더로 같은 입도에서 소성변형 저항성이 다른 14가지 혼합물을 만들었다. 3단계에선 슬래브 공시체(30cm x 30cm x 6cm)를 제조후 반으로 나누어 한쪽 공시체에선 두 개의 김테스트 공시체 코어를 뜨고 다른 한쪽으로는 60℃ 반복주행(WT)시험을 수행하였다. 한편 2단계에선 슬래브 공시체의 가운데에서 WT 시험을 수행하고 그 양옆에서 김테스트 공시체 코어를 채취하였다. 4가지 하중봉을 사용하여 60℃에서 김 테스트를 수행하였다. 침하깊이-반복회수 곡선으로부터 최종 침하 깊이와 동적안정도 두 가지 소성변형 계수를 각 혼합물별로 구했다. 각 하중봉과 골재 별로 K_(D)와 소성변형 계수간의 통계적 상관관계 분석을 수행한 결과 K_(D)와 소성변형 계수와의 결정계수가 매우 높게(R² > 0.9) 나타났다. 그러므로 K_(D)는 소성변형 계수를 추정하는데 있어 매우 적합한 특성치이며 4cm 직경에 1cm 반경으로 원형절삭한 하중봉이 R² 가장 높게 나타나는 하중봉임을 알 수 있었다. 따라서 김테스트는 향후 소성변형을 추정하기 위한 표준화된 특성치로 사용할 수 있도록 더 연구 개발을 할 수 있을 것으로 판단되었다. This study shows predictability of rut parameters of asphalt concrete based on the deformation strength (K_(D)) which is obtained from the maximum load, deformation and size variables of loading head under simple static loading. This paper is the result of latest studies, phases 2 and 3, which are parts of Kim Test study for developing a new strength property, K_(D), for asphalt concrete. Two aggregates, gneiss and granite, with maximum size of 19mm and seven binders using three polymers(LDPE, SBS, SBR) were used to produce 14 different natures of rut resistance mixtures using the same gradation. A slab(30m x 30cm x 6m) was cut into two pieces and 2 cores for Kim test were taken from a half piece and the other piece was used for wheel tracking (WT) test at 60℃ in phase 3. In phase 2, WT test had been carried out in the middle of a whole slab and cores were taken from both sides of the wheel path along the center line. Kim test was performed using four loading heads at 60℃. Two rut parameters, depth of rut and dynamic stability, from the rut depth-cycle curve from a WT test were obtained for each mixture. Statistical analysis were performed for each loading head and aggregate to find out correlation between K_(D) values and each rut parameter. The analysis result showed that K_(D) had very high coefficient of determination (R² > 0.9) on the average with rut parameters. It was found that K_(D) is a good property that has excellent predictability for rut parameter of asphalt concretes, and the 4cm diameter loading head with 1cm curvature radius gave the best result in R². Therefore, Kim test can be further developed as a standard property for use in rut performance estimation of asphalt concretes.

홍순우(Soon Woo Hong),김종진(Chong Chin Kim) 한국식물학회 1960 Journal of Plant Biology Vol.3 No.1
HONG, Soon-Woo, & KIM, Chong-Chin: A study of virus disease on chinese date tree (I). On the external and the internal morphogical characteristics of disease inrected plants. Kor. Jour. Bot. 3 (1). 32-38. 1960 Since the peeuliar virus disease of chinese date tree (Zizyphus jujuba Mill. var. inermis Rehd.) has been noted in South Korea around 1950, 70% to 80% of the economically important trees have been either completely destroyed or infected with the virus, severe damage has been noted, particularly, across the area ranged from middle east to the middle part of Korea, including Seoul area. Yoon,-Koock-Byung in 1958 first reported the disease and described it might be caused by a kind of yellows. But he did not conform in his paper that the disease is pecisely caused by yellows virus. The authors, hereby intend to identify the true cause of the disease of the chinese date tree by studying the external symptoms of the disease and the internal morphological characteristics of the diseaset plant which shows various abnormalities in contrast to the healthy checks. In view of fact that the leaves of the infected plants become yellowish in color similar to the peach yellows, aster yellows, it is likely to be identifiable as the common yellows. Furthermore, the abnormal characteristics observed by the authors are as follow: The floral organs such as petals, sepald, stamens, and pistil turn into vegetative leaves, the leaves on heavily infected plant appear as small sized one and also showing as a common witch`s broom like symptom. There are also an occuring of numerous advantitious shoots developed from both of stems and roots. The amount of photosynthetc starch grains increses iIn parenchymatous cells, necrosis takes place in mesophyll, Partlcularly, Palisade Parenchyma in the leaves of infected plants are distinguished in contrast to the healthy checks. From the symptoms and the present experiments described above, the authors are belived that the disease of chinese date tree is not caused by the yellows. It appears the disease is rather similar to the symptoms of sandal spike virus which was noted in India early in this centry. But the host plant of sandal disease, Santalum album L. and the insect vector, Jassus indicus Wal., have never been reported in Korean flora and the founa. The temperature and the other environmental factors is auite different Korea ard India. Thus the authors believe that the peculiar disease must be an endemic new virus origin in Korea and must be called as shoot cluster disease of chinese date tree.
