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.

김성진(Sung-Jin Kim),박종길(Jong-Gil Park),홍길표(Gil-Pyo Hong),채희영(Hee-Young Chae) 한국조류학회II 2008 한국조류학회지 Vol.15 No.2

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.

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.

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.

세움대 이식(Spreader Graft)을 이용한 비중격 상연 변형에 의한 비만곡증의 교정

박준,홍성표,홍남표 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.3

High septal deformities exert pressure on upper lateral cartilages and nasal bones and cause external deviation of the nose. However, detection of high septal deformities causing deviated noses is very difficult if a detailed intranasal examination is not performed. As well, the high septal border is a difficult area to approach via the endonasal rhinoplasty and is the weakest portion in the septum resulting in much difficulty in correcting deformities and in frequent later recurrence of deviation secondary to the healing process. In order to solve the above problems in 33 cases of deviated nose associated with high septal deformities, the authors evaluated deformities in the high septal border after separation of the septum from upper lateral cartilages and nasal bones. The high septal border is centralized by scoring after resection of the mid or lower-septal portion. And spreader grafts were applied to the convex sides of deviated septal borders to stabilize the high septal border and to prevent long-term recurrence of deviation. Also, to balance the traction force of side walls, the length of both upper lateral cartilages and nasal bones were equalized by resection in the longer side and grafting in the shorter side. Clinical follow-up ranged from 3 to 31 months. There was no surgical or septal complication. Also, there was no incomplete correction, recurrence of deviation, or compromized nasal support. All patients except 2 were satisfied with the aesthetic and functional results. We found that separation of septum from side walls allows detection and correction of higher septal deformities and that spreader graft allows long-term support and prevents later recurrence of deviation.

Objectives : Under an IMF bailout program, our country's financial situation forced people to change many things suddenly. Therefore, this study was attempted to search the aspects of changes of suicide attempts in order to find out how the financial crisis affects people's suicide attempts, the extreme repertoire for psychological change Method : November 21, 1997, the day issued the application of IMF bailout program, is the basic date for comparing the changes, on a certain newspaper(Dong-A daily newspaper). The condition was divided into two, namely before and after the basic date, and the characteristics of suicide were compared between two conditions. Results : The news of suicide increased more after than before the application of IMF situation. (before:105, after:158) Specially, for 30-50 years old, active age in community, the rate of suicide attempts reached twice than that of the others. After the IMF situation, the prominent reason of suicide was the financial crisis. For the type of suicide, the family suicide was remarkably increased after the IMF situation. Conclusion : The frequency of the news of suicide was higher after than before IMF bailout program. The major reason of suicide was the financial crisis. Considering that the social and economic crisis affects people's view of death, psychosocial interventions are necessary for their mental health.

본 연구는 돼지의 체외수정에 있어서 난포란의 회수방법과 체외수정란 및 체외발달율을 조사하여 체외수정의 기본 원리를 밝히고자 본 연구를 수행하였다. 도축장으로부터 채집한 난소의 난포에서 흡입법, 세절법 및 흡입후세절법 등으로 난포란을 채취하여 등급별로 분류하여 회수율을 조사하였으며, 채취한 난포란은 액상정액과 정소상체미부 정액을 사용하여 체외수정을 시킨후 TCM-199 와 NCSU-23 배양액으로 체외배양을 실시하였다. 본 연구에서 얻은 결과를 요약하면 다음과 같다. 회수방법당 각각 37개의 난소에서 회수한 난포란의 수는 흡입법이 1,365개, 세절법이 1,884개 및 흡입후 세절법이 3.830개로써 난소당 난포란의 수는 각각 36.9, 50.9 및 103.5개로써 회수방법간에 유의적(P<0.05)인 차이가 있었다. 액상정액과 정소상체미부 정액을 사용하였을 때 수정율은 각각 83.0 및 83.% 로써 정액간에 유의적(P<0.05) 인 차이는 없었다. 체외수정이 이루어진 난자들의 분할율도 액상정액(60.8%) 과 정소상체미부 정액(69.0%) 간에 유의적(P<0.05) 인 차이는 없었다. 2-4세포기로의 발달율은 24.6 및 28.4%로써 배양액간에 위의적(P<0.05)인 차이는 없었으며, 상실배로의 발달율도 TCM-199 와 NCSU-23 배양액이 각각 14.8 및 24.5% 로써 이들간에 유의적(P<0.05)인 차이는 없었다. To improve the efficiency of in vitro production of embryos with follicular oocytes in pig, the recovery rates, in vitro fertilization and development, and the time required for collectng and processing oocytes by aspiration with or without slicing were evaluated comparatively. The oocytes were collected by aspiration of follicles(2-6mm) with or without slicing ovaries after aspiration, and classified into grade I-IV oocytes by the morpholoy of cumulus cells attached and the homogeneity of cytoplasmic granules. The grade Ⅰ-Ⅱ oocytes were matured invitro for 46 hours in TCM-199 and NCSU-23 supplemented with 1㎍/㎖ FSH, 2IU/㎖ hCG, 1㎍/㎖ estradiol-17 at 39℃ under 5% CO_2 in air. They were fertilized in vitro by epididymis sperm and ejaculated sperm treated with hypotaurin for 24 hours. and then the zygotes were co-cultured in vitro with pFF(porcine follicular fluid) for 7-9 days. The results obtained were as follows: The number of ocytes recovered per ovary was averaged 30.7 by aspiration, 50.8 by slicing and 103.5 by aspiration post slicing. The number of grade Ⅰ oocytes recovered was total 0.2% by aspiration, 0.1% by slicing and 0.1% by aspiration post slicing. The oocytes recovered per ovary was significantly(P<0.05) higher as recovery methods. The cleavage rates of the embryos obtained from 83.0(ejaculate sperm) and 83.1(epididymis sperm) respectively(P<0.05). In vitro developmental rates(9.9 and 18.6%) of embryos cultured in TCM-199 and NCSU-23 up to morula stage were non significantly(P<0.05) different between the culture media.
