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.

국내 팔색조(Pitta nympha) 분포 현황을 알아보고자 전국 국립공원 등 보호지역 중심으로 총 19개 지역을 조사하였고, 전문가 네트워크를 통해 자료를 보강하였다. 전국 19개 지역을 조사한 결과 북한산, 지리산 등 내륙지역 7개 국립공원에서는 팔색조가 확인되지 않았고, 경남 거제, 남해, 해남, 장흥 고흥 등 남해안과 인접한 12개 지역에서 팔색조 서식이 확인되었다. 또한 전문가 네트워크를 통해 수집한 팔색조 출현 위치 정보 82건을 분석한 결과, 전국 8개 광역지자체 모두 팔색조 서식이 확인되었고, 내륙지역(26.8%)보다 해안지역(73.2%)에서 더 많이 출현하였다. 연구 결과를 종합해보면, 우리나라의 팔색조는 주로 제주도와 남해안 지역을 중심으로 많이 분포하며, 그 보다 적은 개체수가 내륙 지역에 넓게 분포하고 있는 것으로 나타났다. The present study investigated the current distribution of Fairy Pitta (Pitta nympha) in South Korea. A total of 19 study areas, including protected areas such as national and provincial parks in South Korea were surveyed, and additional data obtained from an expert network. According to the results, Fairy Pitta was absent in seven inland national parks, including Mt. Bukhan and Chiri parks. Fairy Pitta inhabited 12 areas near the southern coast of South Korea, including Geoje, Namhae, Haenam, Jangheung, Goheung, and Gyeongnam Province. The analysis results of 82 datasets obtained from experts with regard to the locations where Fairy Pitta have been spotted showed that the bird inhabits all the eight metropolitan regions in South Korea, and is more frequently spotted in coastal areas (73.2%) than in inland areas (26.8%). The findings demonstrate that Fairy Pitta is mainly distributed in Jeju Island and the southern coast of South Korea, and is distributed in inland areas at relatively lower numbers.

포획조사를 실시하여 동정된 개체를 대상으로 섬휘파람새(Cettia diphone cantans)의 번식기 울음소리를 녹음하였으며 다도해(홍도), 월출산(춘양리, 도갑사, 금릉경포대)으로부터 총 8개체 240 song을 녹음 분석하였다. 조사지역별 번식기 울음소리의 동질성 검사를 통해 통일 집단 여부 분석결과 다도해(홍도 n=3; 72 song)와 월출산(춘양리 n=3; 80 song, 도갑사 n=1; 68 song, 금릉경포대 n=1; 20 song)에서 모든 조사지역의 개체들이 동일 집단을 형성하지 않는 것으로 나타났으며, 동일 장소에서 녹음한 다도해 홍도 3 개체와 월출산 춘양리 3 개체만이 각각 동일 집단을 형성하였다. 번식기 울음소리의 유형은 다도해(홍도) 5 개, 월출산(춘양리) 5 개, 월출산(도갑사) 4 개, 월출산(금릉경포대) 4 개로 나타났다. 홍도와 춘양리 두 집단의 각각의 상관분석 결과 NNWP와 NNSP, COM이 강한 음의 상관관계(홍도 R=-0.97, 춘양리 R=-0.95)를 나타내었으며, NNSP와 COM이 일치하는 것(두 집단 모두 R=1.00)으로 나타나 본 연구에서 녹음한 섬휘파람새 번식기 울음소리의 경향을 알 수 있었다. 본 연구에서 녹음한 섬휘파람새 전체의 번식기 울음소리는 일관되게 A, B 유형의 두 가지로 분류할 수 있었다. 번식기 울음소리의 두 가지 유형을 T 검정 결과 NNWP, MIWP, DWP, NNSP, MASP, DSP, COM 요인에서 차이가 나타났다(P<0.01). 번식기 울음소리 유형의 조사지역별 및 각 집단 간의 차이는 동종 개체군간의 경쟁 및 번식 전략의 선택과 같은 생태학적 요인과 관련이 있는 것으로 판단되며, 번식기 울음소리 발달상의 변이에 의해 개체별 변이가 나타나는 것으로 판단된다. Communicative interaction are the essence of all animal societies, so it is appropriate to examine communication as a way to gain insight into social structure and thereby generate hypotheses about genetic structure. It is worth pointing out a suggestive pattern in the class Aves, with respect to the approach to genetic population structure by study of vocal communication. Last study of Japanese Bush Warbler Cettia diphone overlooked for distribution and song structure between subspecies. This study is Japanese Bush Warbler Cettia diphone cantans distribution and song structure of the population in South-West Korea. Population distribution researched by banding. Identified Japanese Bush Warbler Cettia diphone cantans record total 8 individuals 240 songs in Hong island, Dadohae National Park and Chunyang-ri; Dogap temple; Kumneung Kyungpo post, Wolchulsan National Park. song homogenity (MANOVA) analyzed each study area. Only the individual which records from identical place formed identical group. Each study site has 5 song types in Hong island and Chunyang-ri, 4 song types in Dogap temple and Kumneung Kyungpo post. But analyzed of all Japanese Bush Warbler Cettia diphone cantans song divided A or B type with parameters (NNWP, NNSP, and COM). Paired t-test against A or B type of song differed from most parameter significant (P<0.01). We analyzed correlation between Hong Is. and Cunyang-ri in sample size, each region was related to negative correlation (Hong Is.: R=-97, Chunyang-ri: R=-95; P<0.01). Moreover, we analyzed NNSP and COM which are accord with correlation (R=1.00). Difference of each study site of song type are thought to intra-species male-male competition and selection of breeding strategy. In addition, repertoire size difference in each site are thought to received the effect of the variation of song development and cultural mutation. Variable variation, that even only affected to song type and repertoire size, and so Japanese Bush Warbler Cettia diphone cantans song study have to much investigation.

Acute arterial occlusion of the extremities is often a surgical emergency and is due mostly to arterial embolus. It has infrequently been reported in the emergency department. Cardiac embolism is most commonly the result of atrial fibrillation secondary to valvular heart disease followed by ischemic heart disease. The emergency arterial embolectomy by Fogarty balloon catheter works well when the cause of occlusion is cardiac embolus obstructing normal vessels in a patient with valvular heart disease. Recently we met some patients with acute critical ischemia of the extremities due to arterial emboli in our emergency department. On physical examination, they all had symptoms of 5"P"s(pain, pallor, pulselessness, paresthesia, paralysis). After emergency arterial embolect omy, immediate improvement was observed in all patients. They were discharged within 1 week. We report our experiences with the review of literatures.

Cadmium(Cd) is an ubiquitous, toxic and nonessential metal which is controversial about the association with a cardiovascular disease. In this study, we investigated the reference level of Cd in myocardium in Korean general population. The level of Cd and zinc(Zn) concentration in myocardium of 252 cases of "sudden and unexpected death" autopsies (male: 172, female : 60) aged 0 to 87 years was analyzed. The concentration of Cd and Zn was determined with atomic absorption spectrophotometer(Perkin-Elmer Model 5100) by flameless and flame method, respectively. The content of Cd and Zn in myocardium showed the log-normal distribution rather than normal distribution. Geometric mean concentration of Cd was 0.19 ㎍/g wet weight in myocardium. The level of Cd in myocardium was not significantly different between male (0.18㎍/g wet weight) and female (0.22㎍/g wet weight). Geometric mean concentration of Zn in myocardium was 25.25 ㎍/g wet weight. The level of Zn between male (25.13 ㎍/g wet weight) and female (25.57㎍/g wet weight) was not different. The deposit of Cd in myocardium was age-dependent of biphasic pattern, but the Zn level by age was not significantly different. The level of Cd in myocardium was increased to the fifties of age, thereafter a leveling-off was shown. The regression model of Cd deposit in myocardium by age was predicted as the following equation: Log Heart-Cd= -1.2726 + 0.0234 ·Age -0.0002 ·Age². The maximum Cd deposit in myocardium was estimated to be 0.26 ㎍/g wet weight at the age of 58.5 in Korean general population. In addition, the total Cd burden in heart by age was predicted as a following equation: Total Cd burden in Heart= -10.165+2.891 ·Age -0.0258 ·Age². The maximum heart burden of Cd was estimated to be 70.7㎍ at age of 55.4. The positive correlation between Cd and Zn was observed in myocardium. The linear regression equation was Log Heart-Zn = 1.4195+0.0262 ·Log Heart-Cd.

The reactions of formation and reduction of perovskite-type LaCoC_3 mixed oxide were investigated by means of thermogravimetric analysis(TG), differential thermal analysis(DTA), X-ray diffraction method (XRD) and infrared spectrometry(IR). According to the simultaneous TG-DTA measurements, it was confirmed that equimolar mixture of lanthanum and cobalt nitrates was decomposed via complex reaction stages and perovskite-type LaCoO_3 oxide was formed as final product at 670℃ in air. In order to clarify the decomposition stages of the mixed metal nitrates, decompositions of each metal nitrates were examined previously. The intermediates and final products were identified by using the X-ray diffractometer and IR spectrometer, and the volatile gaseous species evolved during the decomposition were also detected by IR spectrometry. The reduction reaction of LACoO_3 was studied by means of the sensitive spring balance in the static H_2 atmosphere. It was revealed that LaCoO_3 was reduced through the formation of intermediate with oxygen-deficient structure and to the final products La_2O_3 and Co metal. In the first reduction stage at 256∼416℃, LaCoO_3 was reduced to LaCoO_2.5, in which the color of the sample are initially black and turn to the violet green during reduction. the intermediate was quickly reoxidized in air to original LaCoO_3 oxide. This oxygen-deficient intermediate was further reduced to La_2O_3 and metallic Co through second reduction stage at 470∼620℃. Kinetic study for the reduction of LaCoO_3 was discussed by means of dynamic thermogravimetric analysis method. It showed that activation energies for the first and second reduction stages were 7.6 and 19.6 Kcal/mole, respectively.

박일현,이형표,백성현 성균관대학교 기초과학연구소 1988 論文集 Vol.39 No.2

Sr-doped lanthanum cobalt oxides having perovskite structure, La_1-xSr_xCoO_3 (x=0, 0.2, 0.4, 0.6), were prepared in air at 1000℃ by ordinary solid state reactions and their physicochemical properties including particle morphology, non-stoichiometry, stability and reducibility were characterized by the use of TPR, XRD and SEM techniques. Particle size is not considerably affected by impurity dopant (Sr^2+ ion) but reduction behaviors and thermal stability were markedly varied according to the amounts of Sr (various x values). All these perovskites have oxygen deficient structure as follows. LaCoO_2.94, La_0.8Sr_0.2CoO_2.94, La_0.6Sr_0.4CoO_2.88, La_0.4Sr_0.6CoO_2.83. Finally, kinetics of reduction on each stage was discussed using well-established reduction models and kinetic parameters, activation energy and preexponential term, were evaluated from the optimum reaction model.
