We developed the educational purpose mobile application, named "Wild Flowers of Bukhansan National Park (version 1.0)", aiming for easy identification of wild flowers for students and visitors in the park. When visitors find a flower or part of plant in the park, visitors can search for its name utilizing the pictures and characters provided in their own smartphone mobile devices or tablet PCs. The application provides pictures of wild flowers in the park and character-based searching system based on 12 diagnostic features (e.g., growth form, leaf arrangement, flower symmetry, petal color, petal number, sepal number, etc). We adopted the complete floristic survey of Chung and Lee (1962) and added species that we confirmed their distribution in the park during the development of this application. In summary, number of vascular plants in this park was estimated to be 428 taxa including 100 families, 280 genera, 327 species, 1 subspecies, 50 varieties, and 5 formas. We provided a total of 588 pictures representing 358 taxa and each taxon includes multiple pictures in many cases. Included identification quizzes can be an efficient educational tool as well as fun activity for students and visitors who are learning plant species in Korea. Our next step will include GPS function in the application for indicating visitor's location and for providing previously reported sites of the species that we interested in the map of the park. The future application which includes GPS function will be a valuable tool for the monitoring of rare plants, plant researches related to the climate changes, etc. We currently provide Korean iPhone version only, and English version and both of android versions will be serviced soon.

Research Articles : Geographic Genetic Contour of A Leaf Beetle, Chrysolina aurichalcea (Coleoptera: Chysomelidae), on the Basis of Mitochondrial COI Gene and Nuclear ITS2 Sequences

The leaf beetle, Chrysolina aurichalcea (Coleoptera: Chysomelidae), is a pest damaging plants of Compositae. In order to understand the genetic diversity and geographic variation we sequenced a portion of mitochondrial COI gene (658 bp) and complete nuclear internal transcribed spacer 2 (ITS2) of the species collected from seven Korean localities. A total of 17 haplotypes (CACOI01~CACOI17), with the maximum sequence divergence of 3.04% (20 bp) were obtained from COI gene sequence, whereas 16 sequence types (ITS2CA01~ITS2CA16), with the maximum sequence divergence of 2.013% (9 bp) were obtained from ITS2, indicating substantially larger sequence divergence in COI gene sequence. Phylogenetically, the COI gene provided two haplotype groups with a high nodal support (≥87%), whereas ITS2 provided only one sequence type group with a high nodal support (≥92%). The result of COI gene sequence may suggest the presence of historical biogeographic barriers that bolstered genetic subdivision in the species. Different grouping pattern between COI gene and ITS2 sequences were interpreted in terms of recent dispersal, reflected in the ITS2 sequence. Finding of unique haplotypes and sequence types only from Beakryeng-Islet population was interpreted as an intact remnant of ancient polymorphism. As more samples are analyzed using further hyper-variable marker, further fruitful inference on the geographic contour of the species might be available.

PAV-3의 EIB유전자는 10개의 ORF로 구성되어 있으며, 그 중 아데노바이러스의 단백질과 유사성이 있는 것은 ORF1, ORF2 및 ORF3이었다. ORF1은 Ad41의 19kd 와 BAV-2에서의 EIB ORF2에서의 아미노산의 一致率은 각각 32%와 31%이었다. 2. ORF2는 Ad2 55kd protein과 tupaia adenovirus 44kd protein가 각각 34%로 아미노산 一致率이 가장 높았으며, Ad41의 52kd protein. BAV-3의 EIB ORF3에서도 33%의 一致率을 보였다. 3. ORF1은 61-666 uncleotide (606 bp), ORF 2에서는 429-1,850 uncleotide (1,422 bp)의 부위로 각각 202, 474 a.a로 構成되었으며, 예상되는 분자량은 20 kd와 52 kd이었다. 4. ORF3는 hexon-associated pIX유전자로 추정되며 내부에 1개의 polyadenylation signal(ATAAA)이 1938-1942 uncleotide에 위치하였으며, 이 부위는 TATA box (1937-1942 uncleotide)와 중복되어 존재하였다. Porcine adenovirus type 3 (PAV-3) does not cause severe infection in pigs. Adenovirus has been suggestive of live vaccine vector carrying foreign gene. One of insertion regions is delayed early (EIB) region. However, EIB region of PAV-3 has not been molecularly characterized to date. Nucleotide sequence of EIB of PAV-3 was determined. The EIB region was composed of 1,984 bp and located between 4.0 and 9.7 map units. Three potential open reading frames(ORFs) with low level of homology to other adenoviruses and a polyadenylation signal were identified in the rightward direction of genome. The nucleotide and the predicted amino acid sequences of EIB were compared to those of human and animal adenoviruses. One of the three potential ORFs. ORF1 encoded a polypeptide homologous to bovine adenovirus type 2(BAV-2) ORF2 and human adenovirus type 41(Ad41) 19 kd protein. ORF2 encoded a polypeptide homologous to human adenovirus type 2(Ad2) 55 kd protein, bovine adenovirus type 3(BAV-3) ORF3 and porcine adenovirus type 4(PAV-4) ORF2. The predicted protein of ORF1 had homology to those of Ad41 and BAV-2 with 32 and 31% respectively, whereas the deduced protein of ORF2 had homology to those of Ad2. BAV-3 and PAV-4 with 34, 33 and 29%, respectively.

박정원,이종섭,송준영,김철현,엄중식,정희진,김우주,박승철 대한화학요법학회 2002 대한화학요법학회지 Vol.20 No.2

목적 : 국내에서 1990년대 이후 중요한 병원균으로 대두되고 있는 methicillin-resistant S. ureus(MRSA)는 주로 입원환자에서만 분리되는 것으로 알려져 있으나, 최근들어 지역사회에서도 퍼져있는 것으로 알려지기 시작하였다. 이에 병원획득 및 지역사회획득 MRSA의 임상역학 및 분자역학적 연구를 통하여 획득요인, 병원과 지역사회 획득 균주간의 교류 양상등을 규명하고자 하였다. 방법 : 1998년 1월부터 12월까지 고려대 부속 구로병원에서 임상검체로부터 분리된 S. aureus 균주중에서 MRSA 균주의 빈도를 구하였고, 이중 1998년 10월 1개월 동안 분리되었던 42균주에 대하여 지역사회획득 균주와 병원획득 균주로 나누고, 임상역학적 조사를 하였다. 지역사회 획득 18주와 병원획득 22주에 대하여 PCR 방법으로 mecA 유전자를 확인하였고, PFGE를 시행하여 균주의 클론형(clonal type)을 결정하고 이 결과에 준하여 덴드로그램 분석을 시행하여 분자적 친밀도를 결정하였다. 결과 : 1998년 1년간 분리된 총 1,587주의 S. aeureus 균주중 73.8%(1,163주)가 MRSA 였다. 1998년 10월 1개월 동안 임상자료의 고찰이 가능하였던 MRSA 감염환자 42명 중 20명이 지역사회획득 환자였고, 병원획득 환자가 지역사회획득 환자보다 항생제사용 과거력(17 vs 5, p=0.001), 기저질환의 존재(18 vs 8, p=0.002) 등이 통계적으로 의미있게 높았다. 지역사회획득환자가 이루(7/20[35.0%] vs 2/22[9.1%] ; p=0.041)와 밀접한 관계가 있음도 확인하였다. 분자생물학적연구가 진행된 40주의 MRSA 균주는 모두 mecA 유전자 양성이었고, 18주의 지역사회획득 균주에서 총 8가지의 PFGE 클론형이 존재하였으며 A형이 가장 많았다(7/18, 38.8%). 22주의 병원획득균주에서는 6가지의 클론형이 존재하고 A형이 가장 많았으며(15/22, 68%), 15주의 지역사회획득 균주(83.3%)가 21주의 병원획득균주와 공통적인 클론형을 공유하고 있었다. 결론 : 지역사회 획득 MRSA는 주로 이루나 창상부위에서 많이 분리되는 반면 병원획득 MRSA는 객담에서 많이 분리되고 또한 당뇨병을 가진 환자에서 감염을 잘 일으키는 것으로 밝혀졌다. PFGE 분석 결과 원내감염은 단일균주에 의한 유행양상을 보였고, 지역사회에서도 같은 형의 균주에 의한 감염빈도가 가장 높음을 보여 MRSA 균주가 지역사회로 유입되어 지역사회내 MRSA 감염의 발생에 기여했을 것으로 사료된다. Background : Until recently, methicillin-resistant Staphylococcus aureus (MRSA) infection has been acquired primarily in hospital settings. During the late 1990s, the incidence of community-acquired MRSA infections has been increased in this university hospital. This retrospective study evaluated the clinical features and risk factors for community-acquired MRSA infection compared with hospital-acquired MRSA infection; and molecular relatedness of MRSA strains determined by pulsed-field gel electrophoresis(PFGE). Method: MRSA isolates collected from patients during October of 1998 were classified as community-acquired("community') or hospital-acquired("hospital") cases. MRSA infections were defined as hospital-acquired if organisms were isolated > 48 hours after admission to the hospital or isolated from patients with a history of admission to a hospital within the last 3 months. A comparative analysis of risk factors for community MRSA compared with hospital MRSA was performed. mecA gene PCR and PFGE of MRSA isolated was used as a tool of strain identification and molecular typing. Result : During one month, there were 42 patients with MRSA infection or colonization. Of 42 patients with MRSA isolates, 22(52%) were hospital cases and 20(48%) were community cases. Previous exposure to antibiotics(17 vs 5, p = 0.001) and presence of underlying diseases (18 vs 8, p = 0.002) were more common in hospital cases than in community cases. MRSA were more frequently isolated in otorrhea specimens from patients with otitis media in community cases compared with hospital cases. Of the 40 MRSA isolates subjected for PFGE typing, 18 were community isolates and 22 were hospital isolates. There were 8 distinct PFGE types among the 18 community isolates and type A was the most common clonal type (7/18, 38.8%). 22 hospital isolates were of 6 distinct PFGE types, and type A was dominant clonal type (15/22, 68%). PGFE subtyping indicated that 15(83.3%) of 18 community MRSA strains were clonally related with that of 21 hospital MRSA strains. Conclusion : Our results suggest that hospital MRSA strains may have disseminated in the community setting. PFGE subtyping support the finding that MRSA is circulating beyond nosocomial settings in the regional community.

Onlay graft of the calvarial bone has been popularized in craniofacial surgery because absorption of the calvarial bone is less than that of the endochondral bone. But the problems with using the calvarial bone are its rigidity and difficulty in setting a precise apposition. When the outer tables of the calvarial bone are used for augmentation and reconstruction of the convex zygoma, forehead, or chin, it is better to place the cancellous surface over the convex recipient bone to get a precise apposition. Whereas, it is better to place the cortical surface over the concave nose or orbital cavity to achieve a good apposition. Therfore, our study was designed to determine the differences of bone absorption and regeneration between cancellous and cortial bone contact to facial bone, and between preserved periosteum and detached periosteum in autograft of calvarial bone in dog models. Outer tables of the calvarial bone were placed in subperiosteal pockets of the upper and lower maxilla in four different ways : Group I ; The cancellous surface was placed in contact with the bare recipient bone, and the cortical surface attached with periosteum was accordingly contacted with the elevated periosteum of the recipient bone. Group Ⅱ ; The corical surface attached with periosteum was placed in contact with the bare recipient bone and the cancellous surface was contacted with the elevated periosteum of the recipient bone, Group Ⅲ ; The arrangenent was similar to Group Ⅰ except that the periosteum of the graft was deprived. Group Ⅳ ; The arrangement was similar to Group Ⅱ except that the periosteum of the graft was deprived. Volume measurements using a caliper technique and histological study were made 20 weeks postoperatively. The volume of maintenance is as follows ; Group Ⅰ, 84.2% ; Group Ⅱ, 77.6% ; Group Ⅲ, 77.0%, and Group Ⅳ, 69.5%. The histolgical contribution of living bone was assessed by a modified point counting technique : Group Ⅰ, 86.6%, Group Ⅱ, 83.8% ; Group Ⅲ, 79.6% and Group Ⅳ, 77.6%. Greater volume maintenance and histological contribution of living bone were found when cancelllous surface rather that the cortical were placed in contact with the recipient bone and the grafts from their periosteum were preserved. We concluded that in order to expect better survival of a grafted bone, the cancellous surface of the graft should contact with the recipient bone and that the periosteum of the graft should be preserved.

Plastic surgeons who frequently deal with trauma and deformity of the eyelids and orbits, need have an abundant knowledge of the accurate anatomical morphology and acceptable proportion of them. The normal value of the anatomical morphology and function of the eyelid has not yet been standardized in Korea. The authors measured anthropometry of normal Korean eyelids and statistically analysed in 2,151 individuals including 1,078 male and 1,073 female. Statistical analysis of these measurements offers valuable information about the chronological growth, size, and shape of healthy Korean eyelids. The results are as follows : 1. There was no significant statistical difference between the right and left sides in all measurements. 2. The growth of the eyelid reached the adult level at about 20 years of age and then the growth can be divided into 3 patterns, the first one slowly increased, the seconded one was a stationary, and the last one slowly decreased. 3. The following statistics were recorded for males and females. The cornea-lateral canthal distance was 7.9mm and 7.3mm, the diameter of the cornea was 13.8mm and 13.6mm cornea-medial canthal distance was 7.8mm and 7.5mm the horizontal dimension of the palpebral fissure was 29.7mm and 28.4mm, the vertical dimension of the palperbral fissure was 7.9mm and 8.0mm, the slant of the palperbral fissure was 9.5 degrees an 10.6 degrees, the intercanthal distance was 36.5mm and 37.2mm, the width of the glabella was 24.4mm,. and 24.1mm, the interpupillary distance was 66.1mm and 63.9mm, the ectocanthion-superior margin of the palpebral fissure distance was 14.9mm and 14.2mm, the endocanthion-superior margin of the palpebral fissure distance was 14.9mm and 14.2mm, the height of the opened upper eyelid was 10.3mm and 10.0mm, the height of the closed upper eyelid was 18.2mm and 18.1mm, levator function by the Berke's method was 16.2mm and 15.6mm, MLD was 7.2mm and 7.1mm, and MRD1, was 2.7mm and 2.6mm respectively. 4. The vertical dimension of the palpebral fissure, slant of the palpebral fissure, and height of the double eyelid fold were greater in females than males. The intercanthal distance and width of the glabella was nearly the same in males and females and other measurements were greater in males than females. 5. A double eyelid fold was seen in about 36% of males and 50% of females. The average height of the double eyelid fold with the eye closed in 20 year old females was 5.2mm and 30 to 50 year old females was 5.5mm. The most frequent shape of the double eyelid fold was type 5. 6. The epicanthus was present in 58.1% in this series and existed in over 90% under age 10, but disappeared in about 90% of the people over 50. The most frequent shape of the epicanthus was tarsalis type.

본 연구에서는 산불 피해 소나무재의 이용을 위한 기초자료를 얻고자 역학적 및 건조 특성을 조사하였다. 산불피해재는 종압축 특성, 전단강도, 충격휨흡수에너지 등에서 건전재와 거의 유사한 결과를 보여주었으며, 산불피해재 변재부의 휨특성은 건전재보다 양호하게 나타났다. 건전재와 산불피해재 변재부의 생재함수율은 산불피해재가 다소 낮았으나, 건조속도는 거의 차이가 없었다. 건조시 발생되는 초기할렬은 건전재가 산불피해재보다 발생율이 높았고, 내부할렬은 건전재와 산불피해재에서 발생되지 않았다. 따라서 산불에 의해 피해를 입은 목재의 대부분은 수피부를 제거하여 이용할 경우 건전재와 거의 동일한 용도로서 사용이 가능할 것으로 생각된다. The Mechanical and drying characteristics of Pinus densiflora wood, which was damaged by forest fire, and sound wood were examined. There were no significant differences in axial compressive properties, shearing strength and impact bending absorbed energy between damaged and sound woods. But the bending properties of damaged wood were slightly higher than those of sound wood. The green moisture content of sapwood in damaged wood was lower than that in sound wood, but oven-drying rate was similar in both woods. Number of initial check in damaged wood was smaller than that in sound wood, and inner check in damaged and sound woods was not observed. Consequently, it is considered that mostly damaged wood by forest fire can be used for wood material after removing the considered that mostly damaged wood by forest fire can be used for wood material after removing the bark.

李允中,曺正吉,朴元敎,李康春 成均館大學校 科學技術硏究所 1988 論文集 Vol.39 No.1

A simple and highly sensitive method for the determination of unsaturated fatty acids (C_16:1, C_20:4, C_20:5) is described. I-Bromoacetylpyrene was used as the pre-column fluorescent labelling reagent for HPLC. Fatty acids were derivatized quantitatively into fluorescent compounds by treating with 1-bromoacetylpyrene in the presence of 18-crown- 6 in acetonitrile. The optimum conditions for the derivatization such as, concentrations of KOH, 18-crown-6, and 1-bromoacetylpyrene, reaction temperature and reaction time, were investigated. The derivatives were separated on a reversed phase column (LiChrosorb RP-8, 5 ㎛) using the tertiary mixture of acetonitrile, methanol, and water as the mobile phase. The effluent was monitored by fluorometer (excitation wavelength; 366 nm, emission wavelength; 454 nm). Linearities of calibration curve were obtained between 5.0 p mol and 40.0 p mol. The detection limit of fatty acids was 1 p mol in a 20μl of injection volume.

The purpose of this study is to identify the physical growth in Korean. The subjects of this study include both of male and female, who are attending elementary school, middle school, high school, college in middle and large cities and rural areas. The total number of subjects was 144, 583 persons, including 76,402 persons of male and 68,181 persons of female. The researcher measured the physical status of the male and female - in terms of body height and body weight - through cross - sectional method. On the basis of the results, calculated the standard values of each body structure, the physical and nutritional indices, fatness and estimate the standard body weight, under - and over - weight, the weight of malnutrion and obesity in accordance with age, sex and body height for decision of health level. These surveys and measurements took for 18 months from 1 May, 1988 to 30 April, 1989, and the data from these surveys were analyzed through computer. The results are as follows. 1. Body Measurements 1) Body height (㎝) In the growth condition of body height, rapid growth has been observed among male in the ages 7-15 and among female 7-13. Growth in terms of body height turned out to be slower among higher ages by both sexes, and the average body height of full-grown Korean youth (20-24 age group) was 170.6±7.1㎝ for male and 159.9±6.3㎝ for female. The maximum growth age and annual increment of body height were 10-11 years old and 6.73㎝ per year for female and 11-12 years old and 6.8㎝ for male. These data show a fact thai the female starts to grow earlier than the male by about one year. The age of crossover between the sexes come around 9.5-11.5 years of age, where upon female outgrows male. 2) Body weight(㎏) Rapid growth. in terms of body weight, which was represented by a straight line on a growth curve was observed among the both sexes of 7-15 years of ages and growth turned out to be slower among higher ages by both sexed. The average body weight of full - grown Korean youth (20 - 24 age group) was 63.8±6.8㎏ for male and 52.95±6.0㎏ for female. The maximum growth age and annual increment of body weight were 12 - 13 years old and 6.0㎏ per year for male and 10-11 years old and 5.6㎏ for female. Those data show a fact that the female starts to grow earlier than the male by about two year. The age of crossover between the sexes come around 9.5-12.5 years of age, whereupon outgrows male. 2. Physical and Nutritional Indices 1) Relative body weight Rapid growth, in terms of relative body weight, which was represented by a straight line on a growth curve was observed among the both sexes of 7 - 16 years of age and the age of crossover between the sexes come around 7 - 12.5 years of age. 2) Rohrer index Rohrer index displayed more rich value in case of female than male and in the adolescent period, the level of fullness in lower than after the completion of development. 3) Kaup index In both sexes, Kaup index increased in accordance with advancing ages. The index comes to under 2.02 from 7 to 14 years old in case of male and from 7 to 13 years old in case of female. So the growth of longitudinal axis seemed to be more poor than the one of vertical axis. The index increases beyond 2.0 in case of male of after 15 years old for female. 3. The Fat Amount Through the Method of Measurement of Physical Body In 7 years of age group, the amount of body fat of male was 3.77±1.25 ㎏ and that of female was 9.49±2.24㎏. The amount in creased with age to reach for male in 20-24 age group an average 11.3±2.81㎏ and for female 14.81±2.12㎏. In 7 years of age group, the body fat ( % ) of male was 15.35±5.14% and that of female was 18.01±2.87%. The body fat ( % ) increased with age to reach for male in 20-24 age group an average 17.63±2.67 % and 24.85±4.47 % for female. In cases of male, the body fat ( % ) of 8-13 age group indicated normal range but the other age group indicated higher range. In cases of female, the body fat (%) of below 10 age group indicated lower range and over 11 age group indicates normal range. 4. The Standard Body Weight of the Koreans 1) The standard body weight of Korean youth In case of 7 years age group, correlation coefficient of r=+0.572(p 0.001) between body height and body weight was found in a male group of 2,358 subjects and r=+0. 353(p 0.001) was found in female group of 2,461 subjects, from which respective linear regression equation of body weight and body height was established for male and female as follow : For male ; Y ( B. W, ㎏ )=0.4059×( B. H, ㎝ )-26.1, ( Sy. x =±3.7) female ; Y ( B. W, ㎏ )=0.1471×( B. H, ㎝)+6.3, (Sy. x=±5.4) Similar regression equations of body weight and height were found all age groups from 7 to 19 years old and listed in table 12. 2) Standard body weight of Koreans A correlation coefficient of r=+0.320( p<0. 001 ) between body height and body wight was found in a 20-24 age male group of 7,659 subjects and r=+0.301( p<0.001) in a 20 - 24 female group of 6,693 subjects, from which respective linear regression equation of body weight and height was established for male and female as follows : For male ; Y ( B. W. ㎏ )=0.306×( B. H. ㎝ )+11.6, ( Sy. x =±6.4) female ; Y ( B. W. ㎏ )=0.2856×( B. H, ㎝)+7.3, (Sy. x=±5.7) The standard body weight, under - and over - weight, weight of malnutrition and obestiy of Koreans calculated and listed in table 13-a and 13-b.
