Malaria is a febrile disease caused by protozoan parasites, genus Plasmodium. In Korea., indigenous malaria has been believed to be eradicated by 1984, and, thereafter, all of the reported cases were imported malaria. But since the first case report of re-emerging indigenous malaria in 1993, increasing number of cases were reported reaching more than 350 cases in 1996. However, indigenous malaria in children has not been reported yet. We experienced two cases of indigenous malaria in sisters who were 7 and 5 years old, respectively. Elder sister was presented with periodic fever, splenomegaly and mild headache. She had been to Guam before 4 months of the onset of symptoms. Younger sister was suffered from fever and splenomegaly and has not been abroad. They were diagnosed by examination of peripheral blood smear to be infected with Plasmodium vivax and were treated with hydroxychloroquine and primaquine successfully. These cases are believed to be first re-emerging cases of indigenous malaria in children, and malaria should be included in the differential diagnosis of unexplained febrile children.

북한강 지류 상천천에 서식하는 대륙종개 Barbatula nuda (Nemacheilidae)의 산란특성과 수조 내 산란행동

곽영호,김정배,송하윤 한국어류학회 2023 韓國魚類學會誌 Vol.35 No.1

In order to identify the spawning characteristics of Barbatula nuda, seven surveys were conducted from March to May 2021 in the Sangcheoncheon Stream, a tributary of the Bukhangang River, Korea. During the survey period, 890 individuals were collected, and the sex ratio of female to male was 1 : 1.34. B. nuda spawned 15 March to 24 April, when temperature was 12~15.7°C. Total length of the individual with minimum maturity was 56.7 mm, and it was a 1-year-old. Spawning was observed from individuals with a total length of 80.5 mm more, and it was 2-year-old. The total length at 50% group maturity was 67.2 mm. As a result of injecting 10 IU/g of HCG hormone into B. nuda, about 15 hours later, spawning behavior in which the male wrapped around the body of the female in a circle was observed. After spawning, females and males rested, and fertilized eggs were feed by individuals not participating in spawning. 대륙종개의 산란특성과 산란행동을 규명하기 위해 경기도 가평군 청평면에 위치한 북한강의 지류 상천천에서 2021년 3월부터 5월까지 7회 조사하였다. 전체 조사기간 동안 대륙종개 890개체가 채집되었으며 성비 (♂:♀)는 1 : 1.34로 수컷이 암컷보다 많았다. 상천천의 대륙종개는 수온 12~15.7℃인 3월 15일~4월 24일에 산란하였다. 최소 성적성숙개체는 전장 56.7 mm였고 만 1년생 개체였으며, 전장 80.5 mm 이상 개체부터 산란이 관찰되었고 만 2년생 개체였다. 50% 군성숙전장은 67.2 mm로 나타났다. 대륙종개의 복강에 HCG호르몬 10 IU/g으로 주사한 결과, 약 15시간 후에 산란이 유도되었으며 수컷이 암컷의 몸을 원형으로 감는 산란행동이 관찰되었다. 산란 후 암컷과 수컷은 바닥에서 휴식을 취하였고 바닥에 떨어진 수정란은 산란에 참여하지 않은 개체들에게 일부 섭식되었다.

首都圈에 있어서 서울 中心의 旅客交通圈에 관한 硏究 : 時間과 運賃을 中心으로

郭永浩 동국지리학회 1991 東國地理 Vol.- No.12

The purpose of this study is to establish the passenger transportation areas in metropolitan Seoul with special reference to time distance and passenger fare distance. This study is useful for clarifying an accessibility to Seoul. For the purpose, the author employed the data concerned with bus and rail traffic, and the result was compared with the commuting area and pattern. the results gained are as follows : 1) Within one hour distance from Seoul, the following Shi and gun are covered : Pyungtaek, Ansung, Yongin, Anynag, Osan, Inchon, Suwon, Kimpo, Kumchon, Munsan, Paju, dongduchon, Euijungbu, Kumgok, Paldang, Yangju, Imjingak and Ansan. These ares could be easily reached within 1 hour due to the well developed traffic corridors such as Seoul-Inchon, Seoul-Suwon, Seoul-Kimpo, Seoul-Munsan and Seoul-Chunchon. 2) Within 2 hours distance from Seoul, such Shi and gun as Yonchon, Pochon, Anjung, Yangpyung, Kangwha, Janghowon are included. These areas are lack of continuity in terms of the road networks. 3) As far as time distances are concerned, the Kyungbu and Kyungin axes have high accessibility to Seoul due to high population potential and concentration of efficient traffic services. 4) The largest volume of commuting flow area to the central Seoul is Buchon, Kwangmyung, Kwachun, Guri, Euijungbu, Anyang, Inchon, Songam and Namyangju. These cities are located in the inner suburbs of Seoul. From the viewpoint of time distance, the most accessible transport facility is highway bus, and next national road expressbus, non-express bus and train in turn. 5) Railroad is less accessible than national road express, because of the poor connection in the transportation system. Therefore, it is necessary to construct the by-pass routes for connecting with the inland area, and to allocate many transferable facilities. 6) Because of the fast door-to-door service, the bus is more commonly used than any other public transport facilites. The most developed transportation axes in metropolitan Seoul are the western and the southern parts such as Kyungin and Kyungbu. This is why there are regional disparities within metropolitan Seoul.

韓國都市의 市場潛在力에 관한 地理學的 考察

郭永浩 동국지리학회 1986 東國地理 Vol.- No.7

The aim of this study is to clarify the characteristics of market potential and population potential in Korea, and to analyze spatial interaction and accessibility between the cities by using a quantitative method. Simultaneously, the relationship between the potential and the road connectivity will be investigated by applying the gravity model. The results of this study are summarized as follows: 1. The population potential is densely distributed along the Kyung-bu axis. Furthermore, the population potential occurs in the metropolitan areas which have large population, and the results are well represented by the gravity model. The cities which have high potential are including Seoul, Pusam, Taegu, Taejeon, Kwangju and so forth. The economic policies of the 1960's caused a great influx of rural population into the large cities in which the industrial development was taking place. This created a large population potential in those large cities. 2. The market potential has a tendency to closely correlate with the population potential and it also appears to accord to the Kyung-bu axis. The large market potential is chiefly found in major cities such as Seoul, Pusan, Taegu, Incheon, and Kwangju. the main reason for this stems from the dynamic economic activity which take place in the city and is diffused throughout the peninsula. therefore, large population of the cities acts itself as a labor market, mass consumption, technological and capital pool, and various economic activities, namely urbanization economies. 3. The interrelationship of the market potential and population potential in terms of Spearman's correlation coefficients is 0.89 which indicates a close relationship. In order to have good economic activity, there must be exist a good qualified labour force, which plays an important role as a consumer. And so, high market potential creates a high population potential. Such high market and population potentials led to a concentration of population along the manufacturing belt in Korea, resulting in an imbalances of industrial growth andmany other social problems. 4. Graph theory is adapted to analyze the road connectivity in the 36 cities of Korea and to understand the relationships between population and market potential, and road connectivity. The data for the study are based upon the city population census of 1980 by the National Bureau of Statistics Economic Planning Board and national road networks in Korea. Geographers have attempted to establish a set of precise measures which reflect the major characteristics of the traffic network structure since 1950. There are various traffic measurement techniques, but in this study, only the graph theory analysis method is utilized. Using calculation indexes α, β, γ, the present author compared the connectivity to the population, and the market potentials in terms of the gravity model technique. The resulting calculation are 0.62 (population potential and road connectivity) and 0.64 (market potential and road connectivity) which indicate a close relationship between population, market, and road connectivity. Therefore, we may infer that the highest accessibility areas occurs where the population and market potential is high, and where urbanization level is high too. This study has been conducted at the macroscopic-level of analysis, which only indicate tendencies. It is desirable that a microscopic-level study be conducted in the near future in order to accurately and successfully analyze the potential growth areas of Korea.

곽영호,신중호,정성구,이중의,서길준,윤여규,이창현 대한응급의학회 2002 대한응급의학회지 Vol.13 No.3

Purpose: We conducted this study to evaluate the clinical manifestations of acute hepatities A in an emergency center. Methods: All hepatitis A patients who visited the emergency center of Seoul National University Hospital from October 1999 to March 2002 were analyzed using a retrospective medical record review. Variables included in the data analysis were age, sex, clinical symptoms and signs, and laboratory findings on initial presentation and their peak values. Results: A total of 31 patients showed positive for the anti-HAV lgM antibody, and 29 patients had apparent hepatitis A. The number of hepatitis A cases per month in 1999, 2000, 2001, and 2002 were 1.33, 0.25, 0.92, and 4.3, respectively. Among the 29 patients, 15 were brought to the emergency center and constituted the study group. The mean age were 22.3 years old. The most common symptoms were nausea and vomiting (100%), followed by fever (86.7%), anorexia (66.7%). Common signs were jaundice (53.3%) and hepatomegaly (46.7%). Seven patients admitted via the outpatient department were older and had a longer duration of symptoms from onset to diagnosis than the study group. The mean values of the initial laboratory tests were serum aspartate aminotransferase (AST) of 3,044 IU/L, alanine aminotransferase (ALT) of 3,521 IU/L, and a total bilirubin of 4.15 mg/dL. The peak mean values of those variables were 4,067 IU/L, 4,662 IU/L, and 7.35 mg/dL, respectively. All patients recovered without complications. Conclusion: Patients with hepatitis A showed benign clinical features. This study revealed a trend of increasing incidence of hepatitis A in adults and suggested the possibility of an outbreak. Further effort to prevent the propagation of the disease is warranted.
