This experiment was conducted to examine effects of different polyethylene film mulching, pinching methods, and shading level on growth and root yield of Bupleurum falcatum L. Plant height, leaf length, leaf width, stem diameter, root length, number of lateral roots and number of branches were fewer in a polyethylene film mulching than in a non-mulching. In a non-mulching, plant height was highest at a non-pinching and leaf length, leaf width, root length, root diameter, number of lateral roots, number of branches were greatest at the third pinching (25 Aug.) among the pinching treatments. In a polyethylene film mulching, plant height was highest at a non-mulching and leaf length, leaf width, stem diameter, root length, root diameter were greatest at the third pinching (25 Aug.) among the pinching treatments. Characteristics such as fresh aboveground weight, fresh root weight, dry aboveground weight, dry root weight were greatest in a polyethylene film mulching and total yield per 3.3㎡ was greatest in a non-mulching between polyethylene film mulching and non-mulching. Root yield in a non-mulching was two fold greater than in a polyethylene film mulching, and in a non-mulching, was much greater at the third-pinching (25 Aug.) among the pinching treatments. As the shading level was increased from 0 to 90%, plant height was increased from 83.4 to 100.3cm. Stem diameter, root length, and root diameter were decreased with the increased shading level. Fresh aboveground and root weights were decreased as shading level was increased.

Background: Most cases of Graves' disease have been treated by antithyroid drugs in Korea. The major drawbacks of antithyroid drugs are the relative high rate of relapse and the inconvinience of long term therapy. Measurement of TBII and TRH stimulation test have been considered as the most reliable tests predicting relapse, but the predictive power is not high enough to use in clinical situation. This study was performed to find good prognostic indicators in Graves' disease patients after the discontinuation of antithyroid drug therapy. Subjects and methods : We restrospectively evaluated 96 patients with Graves' disease who showed normal TRH test at the end of antithyroid drug therapy and were followed for more than one year. Serum T3, T4, T3/T4 ratio, TBII, Anti-TPO Ab and TGAb levels were measured at the time of diagnosis and at the end of therapy. Two to three months after withdrawal of antithyroid medication, serum TSH and free T3 responses to TRH were examined. These parameters were compared between the relapse group and the remission group. Results : Among the 96 patients, 22 patients(22.9%) relapsed(Group Ⅱ) and 74 patients(77.1%) remained in remmision(Group Ⅰ). No significant difference was observed between the relapse and the remission group in clinical parameters, serum T3, T4, TSH, T3/T4 ratio, TBⅡ and Anti-TPO Ab determined before and after treatment. Serum TSH and free T3 levels measured after TRH stimulation were also similar in both groups. Serum TGAb levels determined at the end of treatment were significantly higher in the remission group(p<0.05). Relapse following the discontinuation of therapy occured within 24 months in 72.7% of the relapsed cases. After 24 months, relapse rate was reduced significantly. Conclusion : These results suggest that high serum TGAb levels could be a favorable prognostic indicator for the long term remission of Graves' disease treated with antithyroid drugs, and may suggest that Hashimoto's thyroiditis is combined with Graves' disease in those patients.

In this paper, the recursive optinal instrumental vairable method, which estimates noise dynamics as well as system dynamics using pre-filtered data, was propsed. In case of no pre-filtering, the computational burden of this algorithm is equal to that of extended least squares(ELS) methods and less than that of the rescursive maximum likelihood(RML) method. But in case of prefiltering the computational burden of this algorithm is equal to that of the RML, but this algorithm shows faster convergence than ELS and RML algoorithms. Also, vaeious instrumental variables were proposed, and various types of prefilters were prposed to improve the performance of the proposed algorithms. Computer simulations were performed to illustrate the efficiency of the proposed methods.

이 연구는 만 7세부터 17세까지의 신장의 누년적 변화를 통해서 사춘기 최대 성장기와 초경 발생 시기와의 관계를 평가하고, 성장 곡선의 형태에 따라 성장 곡선을 분류하여 각 형태별 특징을 파악하고자 시행하였다. 경기도 화성에 있는 삼괴 고등학교에서 1학년부터 3학년까지 96명의 생활기록부에 기재되어 있는 신장의 누년적인 자료가 이용되었으며, 초경 시기와 전신적 질환 유무는 설문지를 통해 조사되었다. 사춘기 성장 가속기는 9.9세에 시작하여 11.6세에 최대 성장기를 이루고 14.1세경에 끝났다. 초경은 12.6세에 일어나며 76.1%는 최대 성장기 이후에 나타나고 최대 성장기와는 1년의 차이를 보인다. 10.4%에서 최대 성장기 전에 초경이 나타났고 13.5%에서는 최대 성장기와 동일한 시점에 나타났다. 초경 시기와 관계없이 사춘기 성장 가속 기간은 4.2년으로 일정하게 나타난다. 성장 곡선을 4가지 형태로 분류하였으며, A형은 51.1%, B형은 21.9%, C형은 20.8%, D형은 6.2%의 분포를 보인다. C형의 성장 가속 기간이 가장 길게 나타난다. B형과 C형에서 PHV가 두 개인 경우는 B형과 C형의 58.5%인 24명에서 나타났다. 이상의 연구 결과에서 개개인의 성장 양상은 개인차가 크며 초경뿐만 아니라 누년적인 성장을 참고로 하여 onset의 정확한 시기와 성장 곡선 형태를 파악할 수 있다면 남은 성장 기간 예측에 도움을 줄 것으로 생각된다. Objective: This study investigated the onset, peak height velocity (PHV) and end of adolescent growth spurt as well as menarcheal timing deduced from surveying accumulative height growth over many years. Methods: Ninety six students of Samgoe high school between 1st and 3rd grade that were in good health participated in the research. A survey questionnaire was distributed to examine the students’ health status and menarche timing. Results: Adolescent growth spurt typically began at the age of 9.9 and reached a PHV at the age of 11.6. The growth spurt ended at the age of 14.1 on average. The average age of menarche was 12.6 years, which was about one year after the PHV of adolescent growth spurt. In most cases, menarche came after PHV. But in 24% of the students, menarche and PHV was nearly coincident or menarche preceded PHV. The growth curves were classified into four types. A typical adolescent growth spurt showed one PHV on graph that drastically drops after the PHV. However, there were cases with two PHVs. Conclusions: The results indicate that individual growth patterns show large individual differences, however the categorization into the various growth curves may aid in predicting individual growth patterns.

The present work was carried out to investigate the maturing period and the morphology of utricle Codium fragile collected from April 1984 to March 1985 in the coast of Chumgmu southern of Korea. Ranges of water temperature and salinity during the survey period were 7.5∼27.0℃ and 32.9∼34.5%, respectively. The gametangia were produced throughout the year. Mature gametangia were present on plants collected from June to November, whereas most of plants collected from January to May occured as the elongated utricles with both mature and immature gametangia. As for the sexuality, most of plants were dioecious and some monoecious, and there were more male gametophytes rather than female gametophytes. Some plants collected during winter months of December to February were observed as thalli with both brunted and elongated utricles, and male and female gametangia occured together on a single utricle.

The purpose of this paper is to develope a distance education that would be a courseware for a specific object, which can be available for student to learn the necessary knowledge or function, with no restriction of time or place, using WWW and Oracle DBMS. The distance education was designed in this paper consists of bulletin board, subject information, lecturing schedule, online instructions, questions and answers, submit and confirmation of reports, evaluation of lecturing, reference sites, chatting and discussion room, and data bank. The distance education coupled by WWW and database will change the educational form from one-direction to bi-direction between a teacher and the students. This can also provide a multimedia information to the students through WWW environment with convenient user interface. Those benefits made it possible to offer animated audio-visual materials and search for the information concerned through a hypertext technique. Besides, various kinds of informations were stored at database to increase an effectiveness in managing data. Since both teacher and students, are easy to add new information using the process of instruction to the database, the amount of the stored information in the distance education can be expanded effectively.

분무 열분해에 의한 Ba1-xSrxFe12O19계 자성 미립자의 제조 및 특성 변화

Magnetic particles with alternating magnetic field are expected to be useful as thermoseeds in hyperthermic cancer treatment, since they can be targeted and confined to the cancer site. Hard magnetic ferrites such as barium ferrite and strontium ferrite are good candidates for thermoseeds of hyperthermia because of their great hysteresis loss. In order to verify the effect of Sr-substitution to Ba-site, synthesized Ba1-xSrxFe12O19 microspheres with various compositions through spray pyrolysis followed by sol synthesis using barium nitrate, strontium acetate and iron nitrate. Coercive force was increased with increasing substitution amount of Sr whereas magnetic saturation was almost constant. Spherical microspheres with average diameter of 11.7~17.0 ㎛ were produced by spray pyrolysis at 400~1000℃. The mean size was dependent on the pyrolysis temperature and flow rate of carrier gas. In order to obtain a single phase of SrFe12O19 crystal, the spray pyrolyzed spheres were undertaken subsequent heat-treatment above 1000℃. During the subsequent heat-treatment, however, spherical microspheres were agglomerated because of necking between particles. Further study has to be continued working on synthesis of pure SrFe12O19 crystal by means of improvement of pyrolysis temperature scheme and extend the heating period.
