This study was made to get the cultural information for increasing yield with recently improved variety, investigating the effects of different transplanting date and seed size, the number of plant per hill on the growth, and the yield and yield components in rice. The results obtained were summaried as follows: 1. In larger seed, the percentage of germination was higher and the early growth was more vigorous. However, there appeared no effects of seed size in the later growing period. 2. When the young plants sown on April 26 were transplanted on 5th, 15th, 25th of June and 5th of July with 10-days interval, the heading date was promoted in earlier transplanted plots. The days to heading, however, was shortend. 3. In the case of the earlier transplanting in Tongil variety, the maximum number of tillers was increased, the percentage of effective tillers was decreased, and the rate of ripened grains was slightly higher. The yield was the highest in the transplanted plot of June 25. The next came the transplanted plots of 25th, 5th of June and 5th of July. In the early transplanted plot of Palkweong variety, heading was also promoted. The days required for heading were also proportionly shortend, the number of the effective tillers was smaller and the percentage of ripened grains also decreased. The productivity was the highest in transplanted plot of June 25. 4. When the number of plants per hill was increased, the heading date was promoted, the number of panicles was high and the number of grains per panicles was decreased. In the early transplanting of Tongil variety, the yields was the highest in 4-plants plot. When transplanted late, it was the highest in 6-plant plot. In Palkweong variety, there was general tendency of increasing of yield as the number of plants per hill increased. 5. The dwarf disease of Tongil variety and the stripe disease of Palkweong variety occurred much in case of the lesser number of plants per hill and the earlier transplanting.

Confocal laser-induced Raman microscopy has been used to illustrate the applicability of on-chip signal detection for organic solvents on a PDMS microfluidic chip. Binary solvent mixtures with different % concentrations have been injected into the chip using a couple of microsyringe pumps. Concentration of each solvent has been determined from the ratio of characteristic Raman peaks. Confocal laser-induced Raman microscopy is expected to be very useful for the on-chip signal detection of organic reagents in a microfluidic PDMS chip. MEMS 기술을 이용하여 제작한 PDMS 마이크로 칩의 미세 유로를 흐르는 수 UL의 미량유기 용매에 대한 공초점 라만 시그널을 측정하였다. 마이크로 시린지 펌프를 이용하여 PDMS 칩에 서로 다른 농도의 혼합 용매를 주입한 다음 아르곤 이온 레이저를 주사하여 산란되는 특성적인 라만 피크의 상대 면적 비를 계산함으로써 각 용매의 정량적인 농도를 결정하였다. PDMS 마이크로 칩내의 유기 용매 분자에 대한 공초점 라만 현미경 시그널 측정 기술은 다양한유기물에 대한 on-chip 검출 기술로 널리 이용될 수 있을 것으로 예상된다.

This study was designed to examine the mianserin effects on the negative symptoms of chronic schizophrenia. The chronic schizophrenics(N=14) diagnosed by DSM-Ⅲ-R, who were treated at the Catholic University St. Mary Hospital from March 1, 1993 to August 31, 1995, were divided into two groups. One group was composed of 7 patients who were treated with a single classical antipsychotic agent(monotherapy group, MG), and another was composed of 7 patients treated with combined medications(combined therapy group, CG), including classical antipsychotics plus fixed dose of mianserin 30 ㎎/day at bed time. Symptoms were evaluated by BPRS(Brief Psychiatric Rating Scale) and PANSS(Positive and Negatve Syndome Scale) biweekly for 6 weeks, i.e., total 4 times(at baseline, at 2 weeks, at 4 weeks, and at 6 weeks). The results were as follows : 1) Assessed by PANSS, the negative symptoms of CG were statistically significantly improved more than those of MG at 2 weeks, at 4 weeks, and at 6 weeks. 2) Assessed by PANSS, the positive symptoms of CG were not statistically different from those of MG. In both of CG and MG, there was no difference of the positive symptoms across time intervals. 3) Assessed by PANSS, the total symptoms of CG were statistically significantly improved more than those of MG at 2 weeks, at 4 weeks, and at 6 weeks. But, assessed by BPRS, the total symptoms of CG were not statistically different from those of MG. 4) Assessed by PANSS, the general psychopathology symptoms of CG were not statistically different from those of MG. In CG, the general psychopathology stmptoms at 6 weeks were statistically significantly improved more than those of baseline. In summary, mianserin, when combined with classical antipsychotic agent, appears to be effective in diminishing negative symptoms of chronic schizophrenic patients. However, it did not influence positive symptoms.

이정태,최윤정,전양환,성양숙,박원명,김광수,유태열 大韓神經精神醫學會 1997 신경정신의학 Vol.36 No.5

목 적 : 저자들은 자연최면경험과 최면감수성간의 관계를 알아보기 위하여 자연최면점수와 최면유도 척도로 얻은 최면유도점수 및 유도점수와의 관계를 알아보고, MBTI(Myers-Briggs Type Inventory)의 성격유형과 이들의 상호관련성을 알아보려고 하였다. 방 법 : 가톨릭대학교 의과대학에 재학중인 63명의 의대생들을 대상으로 하여 자연최면경험에 대한 설문지와 MBTI를 작성하게 하고 최면유도척도로 최면을 유도하면서 최면유도점수와 유도점수를 얻었다. 결 과 : 1) 자연최면점수와 유도점수 사이에서 양의 상관관계가 있었고, 최면유도점수와 유도점수 사이에도 양의 상관관계가 있었다. 2) 자연최면점수와 최면유도점수 사이에서는 통계적으로 유의한 상관관계가 없었다. 3) MBTI의 각 성격유형들은 최면유도점수와 유도점수 사이에서 양의 상관관계가 있는 것으로 나타났다. 4) 외향형과 사고형의 성격유형은 자연최면점수와 최면유도점수에서 각각 양의 상관관계가 있었고, 자연최면점수와 유도점수 사이에서도 양의 상관관계가 있었다. 5) 직관형과 판단형은 자연최면점수와 유도점수 사이에서 각각 양의 상관관계를 보였다. 결 론 : 자연최면점수는 유도점수와 상관관계가 있었다. MBTI의 외향형과 사고형에서는 자연최면경험이 많을수록 최면유도가 잘 된다는 것을 시사하였다. Objective : We attempted to investigate the relation between naturally occurring hypnotic experiences and hypnotizability. We examined the correlations among hypnotic induction profile scores, natural hypnotic scores, induction scores and MBTI personality types. Methods : Sixty-three medical students completed NHQ(natural hypnotic questionnaire) developed from a list of naturally occuring hypnotic-like experiences and MBTI(Myers-Briggs Type Inventory). HIP(Hypnotic Induction Profile) was also administered to all the subjects. HIP score and IND(induction score) were obtained. Results : 1) The NHS(natural hypnotic score) was significantly correlated with IND in all the subjects. The IND also showed significant correlation with HIP score. 2) There was no significant correlation between NHS and HIP scores. 3) HIP scores were positively correlated with induction scores in all types of MBTI. 4) Natural hypnotic scores were positively correlated with HIP scores and induction scores in introvert and thinking types. 5) There were positive correlations between natural hypnotic scores and induction scores in intuition and judgment types. Conclusion : The natural hypnotic scores were correlated with induction scores. It is suggested that the more the naturally-occurring hypnotic experience is experienced, the better the hypnotic induction is induced in introvert and thinking types of MBTI personality types.

Yang, Moon Yul,Yang, Myoung Kee,Lee, Sang Hak,Wakita, Hisanobu 한국분석과학회 1995 분석과학 Vol.8 No.4

The chemical compositions and pyrolysis characteristics of oil shales and source rocks distributed in the southwestern and southeastern parts of the Korean peninsular have been investigated. In order to compare the results of Korean samples with those of shales giving high oil yields, two Colorado oil shale samples and one Paris source rock samples were also investigated. Chemical compositions of the samples were analysed by means of gravimetry, CHN analysis, X-ray diffraction method, inductively coupled plasma atomic emission spectrometry and atomic absorption spectrometry. A custom made pyrolyser and a Rock-Eval system were used for the pyrolysis studies. Pyrolyses of the samples were carried out by means of a temperature controlling device to $600^{\circ}C$ at a heating rate of $5^{\circ}C/min$ with a helium flow rate of $1200m{\ell}/min$. The results of pyrolysis study indicated that Colorado shale samples belong to type I and all the other samples belong to type II.

High performance twisted and coiled soft actuator with spandex fiber for artificial muscles

Yang, Sang Yul,Cho, Kyeong Ho,Kim, Youngeun,Song, Min-Geun,Jung, Ho Sang,Yoo, Ji Wang,Moon, Hyungpil,Koo, Ja Choon,Nam, Jae-do,Choi, Hyouk Ryeol IOP 2017 Smart materials & structures Vol.26 No.10

<P>This paper reports the twisted and coiled soft actuator (abbreviated with STCA) with spandex fiber. The STCA exhibits higher actuation strain at lower temperature than the previous nylon twisted and coiled soft actuators (abbreviated with NTCAs). While NTCAs are fabricated using a twist-insertion process until coils are formed, a new method is developed to fabricate the STCA using the ultra-stretch of spandex, whereby the STCA is twisted again after the coil has been formed. A 6-gear-twist-insertion device that increases the stability and the fabrication speed is developed to fabricate the STCA. The superior performance exhibited by the STCA is due to the 14% contraction strain of the bare spandex (bare nylon: 4%) and the low spring constant of 0.0115 N mm<SUP>−1</SUP>. The maximum tensile actuation strain of STCA was 45% at 130 °C, and the maximum specific work was 1.523 kJ kg<SUP>−1</SUP> at 130 °C. STCA could repeatedly actuate 100 times with a strain change of less than 0.4%.</P>

기대효용이론 위배현상의 학습효과

김양열(Yang Yul Kim) 한국경영학회 1996 經營學硏究 Vol.25 No.1

Since the famous Allais` experiment, many studies have reported the limitations of the expected utility theory based on Von Neumann Morgenstern axioms. They claim a significant portion of subjects on the average make a choice violating the EUT. This is a micro-study to identify what type of individuals is more likely to violate the axioms. This paper examines the effect, of the information processing capability of individuals which is accmulated by learning. The subjects participated in a series of experiments are grouped into three by their information processing capability, and the ratios of subjects violating the EUT are compared. The group with higher capability showed significantly lower violation ratios in most of the problems investigated. This result implies that the rational decision-making capability of individuals can be built up by learning, and the more rational decision-maker will show his preference conforming to the expected utility theory.

When we present some information, we can use application programs through multimedia-based authoring tools. Especially, many programers proposed to improve its integration time and reduce programming speed and easy to use. However, multimedia based authoring tools have not all of programming methodologies and do not supply special functions from user''s request. Therefore, we have to apply effective functions through high-level programming languages.In this paper, we propose to use small application programs through dynamic linking methods. So we reduce overhead from memory loading. In authoring tools, we can use MCI(media control interface) call functions for playback audio files. We development ATS(Auto Transition System) for several functions-close MCI call audio files, get object status, page-to-page transition. We evidently show that an optimal configuration of presentation obtained by ATS algorithm.
