게르마늄의 약리효능이 알려짐에 따라 게르마늄이 깅화된 기능성 농산물의 요구도가 높아지는 추세이다. 본 연구는 게르마늄의 농업적 이용에 대한 기초 사료를 제공하고자 실시하였으며, 벼의 생육 및 게르마늄 흡수에 미치는 게르마늄처리 효과는 다음과 같다. 게르마늄을 0, 2.5, 5.0, 7.5 및 10.0 mg/kg으로 처리할 토양을 와그너포트에 넣어 벼를 재배힌 결과, 게르마늄 처리농도가 증가할수록 게르마늄 독성의 증가로 초장, 수장, 수수 및 수량이 급격히 감소하였으며 게르마늄 2.5 mg/kg 이상에서는 게르마늄 독성이 발생하였다. 게르마늄 처리농도가 증가할수록 벼의 게르마늄 흡수랑은 증가하였으나 벼의 게르마늄 이용율은 게르마늄 2.5, 5.0, 7.5 mg/kg 처리에서 각각 20.7, 12.5 및 7.5%로서 게르마늄 처리농도가 증가할수록 감소하였다. 벼의 부위별 게르마늄 함량은 볏짚>왕겨>현미 순으로 높았다. 게르마늄 2.5 mg/kg 처리시 볏짚, 왕겨 및 현미의 게르마늄 함량은 각각 103.4, 30.2 및 3.02 mg/kg 이었고, 볏짚과 왕겨에서는 게르마늄 무처리에서도 각각 2.9 및 3.9 mg/kg을 함유하고 있었다. 쌀의 아미노산 함량을 분석한 결과 게르마늄 처리농도가 증가할수록 Asx., Thr., Ser. 등 대부분 종류의 아미노산 함량이 증가하였으며, 그 결과 현미중 질소흡수량도 증가하였다. In order to obtain the basic information for agricultural utilization of Germanium(Ge), the growth characteristics and Ge absorption of rice plant were investigated with different Ge concentration in soil. Ge concentrations were treated with 0, 2.5, 5.0 7.5 and 10.0 mg/kg in pot(1/5,000a), respectively. As higher the Ge concentration in soil, the Ge absorption amount in straw, husk and brown rice were increased. But the yields were decreased with the increase of Ge phytotoxicity. When rice plant was grown more than 2.5 mg/kg Ge(as GeO₂) in the soil, growth was inhibited by germanium phytotoxicity and necrosis spots were observed in the rice leaf blades. Therefore the optimum concentration of Ge was less than 2.5 mg/kg in rice plant. When rice plant was cultivated on soil supplemented with 2.5 mg/kg Ge, Ge content in straw, husk and brown rice was 103.4, 30.2 and 3.02 mg/kg, respectively. The Ge content in plant was high in the order of straw > husk > brown rice. Most of the amino acids in rice were increased with the increase of Ge treatment, besides, total amino acid contents also increased.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

Genetic Characterization of Haemagglutinin 1 Domain of Influenza B Viruses Isolated in Korea during $1988{\sim}1999$

Although Korean influenza virus isolates have been genetically associated with the vaccine strains of the corresponding year, influenza B viruses have prevailed almost every year in Korea during the past decades. We have 'analyzed the genetic characteristics and evolutionary patterns of the haemagglutinin (HA) 1 domains of influenza B viruses isolated during 1988-1999 using direct RT-PCR and sequencing. Phylogenetic analysis of influenza B viruses isolated in Korea indicated that antigenically and genetically distinguishable strains of the lineage II and lineage III variants had been cocirculated. Variants prevailed in early 1990s are represented in 1996/97 and 1998/99 and some different variants have been co circulated geographically and prevailed concurrently in Korea. All HA1s of Korean isolates have amino acid substitutions mainly in the region between position 124 and 310, which was previously proposed an immunodominant region. Insertion-deletion patterns of the HA gene revealed that Korean influenza B viruses were evolved from Lee40 with different manner between lineage II and III viruses. Lineage III viruses were also divided into two groups as conserved group and inserted group, in relation to Lee40. But lineage II viruses had evolved with directional pattern. Antigenic index proposed that influenza B isolates prevailed since 1996/97 seasons might had emerged from the antigenic variants of a Seo1697-like virus and that new variants might appear from the lineage II viruses resulting in persistent prevalence in Korea.

Under the current energy crisis over the world, energy conservation should be urgently sough in every related aspect and hence the heat conservation design of dwelling house is accordingly a prevailing task to architects and engineers. This study deals mainly with the design concept on the architectural point of view and prepares a guide for the design of the distribution of solar radiation in the peninsula. The major findings are as follows: 1) In measuring the heat transmission and in its calculation, the thermal conductivity should be applied taking into account to the regional variation and in general 5-8 Kcal/m²h ℃ and 20-30 Kcal/m²h ℃ are recommended as the heat transfer coefficient, for inner and outer surface respectively for the practical purpose. Details for design are shown in a figure and a table. 2) Taking into consideration the locality at 24 regions, D^16.5-10.5 Degree day shows variation ranging from 1,048 to 2,666. 3) Economic justification of heat conservation works should be analyze in relation with Degree day. 4) Calculation with field survery date demonstrates that outdoor temperature for heating design ranges from -4℃ to -15℃ below the freezing point over the nation except Cheju-Island. 5) The use of heat insulation materials is strongly recommended in material design for house energy saving and the standard of K-value applied to new house should be prepared.

In Conclusion, it is demanded that we throw away a fixed idea that commercial sports facilities are inferior and that we think its desirable direction of development and prepare a positive policy for it as a social physical education sports facility. We ought to not control it by using the laws of merrymaking businesses but consider the way to guide, assist, and encourage it at a dimension of Physical education development from seperate point of view as stated above. It Plays roles to replenish the shortage of public sports facilities especially in our country, So we first evaluate its roles to be being carried out and its performance limit properly and need to grasp newly the roles of public, private and commercial physical education and sports facilities in the whole organization of social physical education. While the national interests and demands in sports are being expended and accelerated nowadays, if commerical sports facilites are negleated in the contempt and indifference in the actual situation of these days, witout the reasonable conversion of conciousness of the people in the administration authorities about this or the propulsion of constrution of public facilities, the menbership free of menbers using facilities will inevitably soar, the approach of most general public enjoying sports to these facilities will be more difficults, and the alienated people from sports facilites may diffuse the conflict and stress caused by a remarkable contrast of the wealth of money by doing various kinds of antisocial and unadaptable behavior and by drinking too much enough to injure health. These make sports for participating and acting disappear and make sport for just hearing and Watching. This was happended severely in the past and it turns away the essence of soprts while the former is a conflict among castes caused by the superiority and inferiority of sports technics, but a phenomenon of these days is a conflict among castes caused by the distinction of the wealth of maney. This promotes the feelings of distance among people and misleads the vigor of living sports, the sports of our life.
