웹 브라우저 환경에서 통신 및 화면 갱신 기능을 제공하기 위해서 최근까지 ActiveX를 제공하였다. 하지만 ActiveX 배포에 따른 보안 문제 또는 Spyware 등으로 인한 개인 정보 노출 가능성을 배제할 수 없게 되었다. 따라서 본 논문에서 제안하는 웹 브라우저 환경에서의 통신 모듈 및 화면 갱신 기법을 통해서 ActiveX의 단점을 보완하려 한다. 또한, 여러 분야에서 적용 가능하지만 NMS 원격 감시 모니터링의 시뮬레이션을 통해서 적용 가능성을 검증하였다.

The effects of vernalization and darkness on flower initiation were reviewed by using naked barley varieties. The dark effects were pronounced on flower induction even at 25$^{\circ}C$. There were no differences in flowering responses among varieties. The effects of vernalization and darkness combined with 25$^{\circ}C$were 100% and 60% respectively which showed a significant difference. When the alternation of darkness with light was taken as first and last the flowering rate was 92 percent. When it was intercalated by light treatments the flowering rate was 91 per cent. Thus the effects of vernalization and darkness seems to differ.

Immature embryos were tested for investigating the effect of cold treatment duration and GA$_3$ concentration on the vernalization response in barley. Immature embryos were cultured on B$_{5}$ medium with GA$_3$ for 5 days, and were transplanted under 20/15$^{\circ}C$ temperature after cold treatment. Germination rate and shoot length were increased more in 20-day-old embryos than those in 13-day-old ones but germination day was decreased. Addition of 1 or 10 ppm of GA$_3$ to B5 medium was effective on the growth of immature embryos. The higher GA$_3$ concentration was, the shorter time from embryo culture to flag leaf emergence and heading was. The earlist flag leaf emergence and heading were showed on treatment of 1 or 10 ppm of GA$_3$, but GA$_3$ did not completely replace vernalization. The days to flag leaf emergence of immature embryo-cultured barley with cold treatment for two and three weeks was shortened by 3 and 18 days at 1 ppm GA$_3$, and 16 and 20 days at 10 ppm GA$_3$, respectively, when compared to 0 ppm GA$_3$ culture with cold treatment for three weeks. It was at 10 ppm GA$_3$ with 3 weeks cold treatment that showed the lowest culm length, spike length and number of grain per spike. GA$_3$ concentration was not correlated significantly with each character in 1 week cold treatment, but was significant with each character in 2 weeks. In 3 weeks cold treatment, it was except for days to heading. Correlation between cold treatment duration and culm length was negative in 0 ppm GA$_3$. In 1 or 10 ppm of GA$_3$, all characters had highly negative correlation with cold treatment duration.n.

The physical function. congnitive performance and the depression of the elderly persons of over 60 years in Pusan Kyungnam Province are studied. For the survey, prepared is a questionnaire which includes 14 items for the physical function, 8 items for the cognitive performance and 12 items for the depression. totaling 34 items. The interactions of the items of each category are analyzed in terms of daily life performances. The results show that. the elders have the problems in cognitive performance rather than the physical function or depression, and there are great variances depending on the individual's background.

The purpose of this study is to know the value of the photographic subtraction technic in the transcranial oblique lateral projection of the TMJ. The author examined the transcranial oblique lateral projection radiographs which comprise 50 cases of 32 persons, compared the transcranial oblique lateral projection films and those subtraction films. The following results were obtained. 1) The condyle at closed jaw position had showed a reversed tone image, but the condyle at the opening position had showed a re-reversed ordinary image. Both condyles had showed one subtraction film because radiographic interpretation of TMJ was easy. 2) On 50 cases of subtraction films, 46 cases had showed same radiographic images compared with trascranial oblique lateral projection films. Four cases (3 cases of erosion, 1 cases of sclerosis) had showed additional changes of images so that capability of interpretation was improved.

The primary purpose of this study was to investigate how number sense performance of sixth graders was and what every character of five components of number sense possessed by sixth graders was. For the this purpose, Two kinds of studies were conducted : a descriptive study by pencil-and-paper tests(Basic Test, Number Sense Test) and a clinical study by interviews. The conclusions drawn from the results obtained in the this study were as follows : First, students were highly scored in Basic Test but not highly scored equally in Number Sense Test. Second, students hardly used the benchmarks and lacked consideration of the reasonableness about computation results. Interview results were that students' notion about the meaning, and the greater - than and less - than relations for fractions was weak and students tended to not use number sense but apply standard algorithm and compute numbers in the question without thinking.

지난 10월 10일부터 17일 까지 경복궁 특별전시장에서 열렸던 「제4회 전자 전람회」는 내적 외적으로 커다란 결실을 거두었음이 틀림없다. 전시품목만 하더라도 230종에 5만여점이었으며 이기간 동안 근 10만명에 가까운 관람객이 모여들었다. 국내는 물론 국외 Buyer들의 눈길을 끈 각종 전자제품의 전시를 통해 관람객들은 한국 전자공업의 밝은 앞날을 내다볼 수 있었으며 다양화, 국제화 되어가는 전자공업의 투자영역을 실감할 수 있었다. 특히 이번 전자전에서는 600여명의 외국투자가와 Buyer들이 내한하여 현장에서만도 3천1백만 달러의 거래상담이 이루어져 우리나라 전자업계의 희망찬 내일을 기약케 했다. 100억불 수출을 목표로 하는 전자공업의 진흥발전을 위해 우리는 이 시점에서 무엇을 어떻게 다져나가야 할 것인가? 이번 전자전을 직접 주관했던 한국정밀기계센터 이사장 이춘화씨는 우리나라 전자공업계가 지향할 길을 다음과 같이 제시했다.

The purpose of the present study is to analyze leadership of the public library organization in Korea using Fiedler's Contingency Theory. The study is only to analyze leader-member relations, task structure, position power of the public library organization in Korea by questionnaire method. After follow-up mailing, of the 143 responses received from librarians in 16 public libraries of Pusan and Kyung Sang Nam Do, 111 responses are analyzed. The results are summarized as follows: 1. Leader-member relations of public library organization in Korea are good. 2. The task of public library organization in Korea is unstructured. 3. The position power of public library organization in Korea is strong. In the light of this situation, relationship-oriented leaders will be more effective than task-oriented leaders in the Korean public library organization.

CVT(Continuously Variable Transmission) is one of the most promising candidates for the future automobile transmission because of its continuously variable gear ratio and reduced shift shock. It is also possible to operate the power source at its high efficiency region with CVT. The CVT system consists of thrust plate, driving pulley, belt, driven pulley, and preload spring of output shaft. In this paper, the dynamic modeling of a CVT system is completed to obtain the static performances of CVT system. A simulator is implemented on Matlab(Simulink), which can analyse the static performances of a CVT system. The methods for improving the total efficiency of a motorcycle system are also proposed based on the simulation results. In this study we increase the capacity factor of CVT up to the three times of default specification.
