The caudal subnucleus of the spinal trigeminal nucleus (medullary dorsal horn ; MDH) receives direct inputs from unmyelinated and thinly myelinated, small diameter primary afferent fibers. Thus, the MDH is implicated in the processing of nociceptive information in the orofacial region. In this study, the types and characteristics of voltage-dependent ion currents were investigated in acutely isolated MDH neurons of postnatal rats by means of the whole cell patch clamp techniques. Coronal slice (400㎛) of the trigeminal caudal subnucleus region was sequentially treated with pronase 0.2㎎/㎖. then single neurons were mechanically dissociated. Voltage-dependent sodium currents showed that the half-maximum activation potential was -41.8±1.8mV and half-maximum inactivation potential was -62.4±3.0mV. And the currents were blocked totally by application of 100nM tetrodotoxin. In a Ca^2+ free solution, low-threshold transient (I_A) and high-threshold sustained (I_K) currents were recorded. The half-maximum activation and inactivation potential of I_K were 2.5±1.9mV and -37.1±2.3mV, respectively. I_A was activated and inactivated more rapidly than I_K. The half-maximum activation and inactivation potential were -21.6±6.3mV and -84.5±5.0mV, respectively. When a 4-aminopyridine of 5mM was applied, I_A was almost totally blocked. These results reveal that MDH neurons express a variety of voltage-dependent ionic currents with distinct physiological and pharmacological properties, and they play an essential role in the transmission and modulation of sensation, especially pain, from trigeminal region.

군산시의 생활 쓰레기 발생량은 총 282톤/일으로 조사되었으며 일반쓰레기의 조성비의 주개류가 전체의 65.0%이상를 차지하여 가장 높았으며 다음으로 종이류 20%, 금속류가 10.0%, 수지류가 6.4%, 나머지 비철류, 유리류순으로 조사되었다. 또한 삼성분의 분석결과는 수분함량은 55.9% 회분함량은 8.4%, 가연분 함량은 35.7%로 조사되었다. 또한 쓰레기의 발열량을 조사해 본 결과 평균 발열량은 4,437kcal/kg, 고위발열량 4.321kcal/kg, 저위발열량 3.979kcal/kg, 저위습윤 발열량은 1.584kcal/kg으로 나타났다. 원소분석조사값은 탄소 53.0%, 수소 36.0%, 산소 36.0%, 질소 2.6%, 유황 0.1% 염소는 1.2%로 조사되었다. 전체 쓰레기의 가연분량과 비가연분량의 비는 69:31로 조사 되었다. 본 연구 결과 군산시 일반쓰레기는 정부의 음식물 쓰레기 줄이기 운동으로 인하여 감소하는 추세를 보이고 있으나 아직도 미비한 실정이었으며, 보다 효율적인 음식물 쓰레기 처리 방안을 모색하여 사료화, 비료화로 재활용한다면 쓰레기 배출량과 매립량이 현저하게 줄 것으로 사료된다. After the enforcement of the volume-base charge system, the composition and the physico-chemical characteristics of municipal solid wastes(MSWs) from 2 different sources in Kunsan were investigated for the whole year of 1996. The sources are from residential, commercial area. The average composition of MSWs was composed of 60% of food wastes 30% of paper & cardboard, 0.8% of vinyl & plastics and 1.2% of the others. The season average Low-heating values of MSWs, both based on element analysis and bomb calorimeter, were estimated to be 1.584kcal/kg and 15.76kcal/kg, respectively.

The Survey was conducted to find the present situation and to recommend the effective ways at the Work Experience Progran in the Colleges of Agriculture. A series of responses for the researcher developed questionnaires were obtained from the 370 students and 77 experience program supervisors and farmers. Another interviws were made with the administrators or professors in the 24 agricultural colleges for abtaining the informations, ideas and recommendations. According to this research, we found that we could imporve the Work Experience program strenuously but not now. Most experience program supervisors and the farmers suggested the most effective way to improve the program as follows ① Students should be motivated for active participation.② Work Experience Program must be fitted to their profession and Department. ③ It should be conducted under the scrutinized and careful plan. ④ Evaluation of the program should be improved and supervision of the place supervisors and farmers should be encouraged.

통계적발취검사법의 위상적인 一般化硏究

최춘호,김용운 漢陽大學校 1979 論文集 Vol.13 No.-

It is well known that the limit theorems of probability theory, which previously dealt primarily with the theory of summation of independent Radom theorems, have been extended to the theory of stochastic process. The authors attempt a new approach to limit theorems which can be used for many topological spaces in which in general no compleate metric exists. The authors introduced almost convergent topology in the spaces of 1st kind of discontinuous function and generalized the above mentioned results.

In this study, as preliminary research for the development of natural estrogen supplement the chemical properties of Iranian black pomegranate juice concentrate and seeds were evaluated. Proximate compositions of pomegranate juice concentrate and seeds were as follows; crude lipid 0.4% and 8.2%, moisture 39.9% and 6.6%, crude protein 0.9% and 12.2%, ash 1.4% and 1.7%, and carbohydrate 42.0% and 84.5% respectively. Major amino acids are glutamic acid (1310.0ppm) and aspartic acid (896.2ppm) in juice concentrate, and glycine (611.1ppm) and arginin (401.6ppm) in seeds. Ascorbic acid has the highest concentration of 20.0mg/l00g in juice concentrate and 0.23mg/l00 in seeds. The compositions of unsaturated fatty acids such as linoleic acid and linolenic acid were higher than those of saturated fatty acids such as stearic palmitic acid. Major minerals were potassium, calcium and sodium, potassium was highest in both juice concentrate and seeds. Vitamins were composed of ascorbic acid (20.0mg/l00g), vitamin B$_1$ 수식 이미지(0.12mg/100g) and niacin (0.80mg/l00g) in juice concentrate, and only ascorbic acid(0.23mg/l00g) in seeds. Organic acids such as citric and L-malic acid were detected only in pomegranate juice concentrate. The contents of total polyphenols were 4.55g/L in juice concentrate and 3.5mg/l00g in seeds, respectively. Phytoestrogens detected in pomegranate juice concentrate and seeds were daidzein, quercetin, genistein and 17β-estradiol.

정전척의 유전체 물질로 열전도도와 유전특성 그리고 기계적 특성이 우수한 알루미나에 TiO₂첨가하여 유전체의 비저항을 변화시켜서 정전척(electrostatic chuck)에서 발생하는 정전력인 쿨롱힘(coulomb force)과 존슨-라벡힘(Johnsen-Fahbeck firce_의 영향을 규명하려 하였다. 그리고 비저항, 인가전압, 온도, 습도가 정전력에 어떠한 영향을 주는지 고찰하였으며, 인가전압에 따른 응답 특성에 관하여 고찰하였다. Alumina electrostatic chucks for silicon wafer process with wide range of electrical resistivity were fabricated by controlling the amount of TiO₂ addition (0 wt%, 1.3 wt%, 2 wt%, 2.8 wt%). The dependence of electrostatic force on applied voltage, temperature and humidity was investigated. In addition, response characteristics on applied voltage and relationship between electrical resistivity and electrostatic force characteristics such as Coulomb force and Johnsen-Rahbeck force were discussed

Using modified self-report questionaire composed by Dr. Oh, Dong Won and his associates(1986), the concept and attidtude of the schizophrenic outpatients toward antipsychotic medication was investigated. The subjects were 151 chronic schizoprhenic outpatients in Seoul National Mental Hospital during the time from July 1. to Aug 31., 1987. The significant results were as follows. 1) 80.2% of the subjects responded as "drug can help improve their illness" but only 45.6% of them reported to take drug voluntarily. 2) Regarding to the greatest benifits of antipsychotics, "to improve insomnia" was most popular response(53.2%). 3) The favored method of medication was "by oral"(97.2%), its frequency was "once a day in the evening"(50.0%) and the number of drugs taken was "less than 5 per day"(69.2%) 4) 79.9% of the subjects had some experiences of "unwillingness to take drugs" which was mainly accounted by "unpleasant side effects"(30.9%) 5) 48.2% of the subjects reported that antipsychotics might have "habituation potential" and 60.9% reported that antipsychotics would have "adverse effect on the body" 6) 61.5% of the subjects accepted the necessity of drug continuation ordered by doctor and the main reason of drug continuation was "to help treatment"(44.2%), while the main reason of drug discontinuation was "unnecessary because of being cured of disease"(50.0%) 7) It was reported that the most unpleasant side effect of antipsychotics was tremor, followed by sedation and constipation. 8) Demographic variables(ie ; duration of illness, number of previous admission, educataion) were compared in two groups using χ²-test. The statistically significant results were as follows. (1) The number of patients answering that they world take medication "voluntarily" and world take "more than 3yrs" was higher in the longterm patients. The number of patients answering that they are "dissatisfactory" on medication was higher for short-term patients. (2) The rate of "complete effectiveness" regarding to the concept on the value of antipsychotics was higher in the group who had less frequent number of previous admission. (3) The rate of "pharmacotherapy"(the proposed treatment method) was higher in the high education group.
