Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

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.

「気持ち」「気分」「機嫌」의 비교연구 : いい·わるい와 결합하는 경우를 중심으로

全成龍 청주대학교 인문과학연구소 2018 人文科學論集 Vol.57 No.-

日本語における「気持ち」「気分」「機嫌」という三つの言葉 は、韓国語において、一般的に「기분」という、一つの言葉に翻 訳される。言い換えれば、韓国語における「기분」という言葉 は、日本語において、「気持ち」「気分」「機嫌」という三つの 言葉に翻訳されるわけである。それでは、日本語において、「気持ち」「気分」「機嫌」とい う三つの言葉の違いはないのであろうか。このことを出発点とし て、ここで、これらの言葉が「いい」「悪い」という形容詞と組 み合わされる場合に限定して、この三つの言葉が表す意味の違い を明らかにしたのである。すなわち、日本語における「気持ち」という言葉は、視覚·聴覚· 觸覺などの感覚を表すものであり、「気分」という言葉は、肉体 的な苦痛や爽快を表すものであり、「機嫌」という言葉は、精神· 心理的なことを表すものである。

「~にくい」와「~がたい」의 비교연구

전성용 청주대학교 인문과학연구소 2020 人文科學論集 Vol.61 No.-

これは、日本語の類義語の一つである「~にくい」と「~がたい」について、比較研究したものである。これらの二つの単語は、品詞的には同じ接尾辞であり、「~にくい」と「~がたい」 は、共に動詞の連用形について形容詞を作る特徴も同じである。また、「~にくい」と「~がたい」は、漢字で表す時も、二つ共 「~難い」で、表記も同じであり、意味も「~することが難しい」ということで、二つの単語が非常に似ているのである。しかし、現在これらの単語が二つ共使われている以上、どこか用法・あるいは使い方の違いがあるのは明らかなので、日本語の作品の 中から、これらの単語が使われた用例を集め、分析し、これら二つの単語の使い方の違いを明らかにしたのである。

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.

전주연,이갑상,신용서 한국식품영양학회 1999 韓國食品營養學會誌 Vol.12 No.2

단백질성의 치아우식 예방제를 개발하기 위해 polylysine을 선정하고 Streptococcus mutans와 Lactobacillus acidophilus의 생육과 산생성량에 미치는 영향을 anaerobic broth system에서 미생물학적인 방법에 준하여 조사하였으며, polylysine의 항균활성에 대한 pH와 열 안정성을 조사하였다. Streptococcus mutnas와 Lactobacillus acidophilus의 생육은 polylysine의 첨가농도가 증가할수록 감소하였으며 1.0㎎/ml 이상의 첨가농도에서는 두 시험균의 lag time이 약 1시간 정도 연장되는 효과가 있었다. 시험균의 산 생성량도 polylysine에 의해 감소되었으며 특히 1.0㎎/ml의 첨가농도에서 그 효과가 뚜렷하였다. Polylysine은 pH 5.0∼8.0에서도 그 항균활성이 유지되었으며, 60℃에서 30분간, 120℃에서 15분간의 열 처리에도 그 항균활성이 소실되지 않았다. To evaluate antidental caries activity of polylysine, cell growth and acid production of Streptococcus mutans and Lactobacillus acidophilus were microbiologically monitored in anaerobic broth system containing various concentration of polylysine. The pH and heat stability of polylysine having antimicrobial activity were also examined. Two tested microbes were fairly well grown in broth containing polylysine 0.1㎎/ml, however, inhibited at 1 and 2 ㎎/ml of polylysine concentration. Especially, lag times of Streptococcus mutans and Lactobacillus acidophilus were prolonged to about hour at 1.0 and 2.0 ㎎/ml of polylysine. Acid production of Streptococcus mutans and Lactobacillus acidophilus was also decreased by polylysine. Antimicrobial activity of polylysine was not affected by the change of pH and the heat treatment.

이용준,정성춘,이학기 東亞大學校 建設技術硏究所 2004 硏究論文集 Vol.27 No.2

The hazard factors in building construction project are various and their bad effects with regard to project's efficiency are increasing due to its enlargement and complexity. However. the assessment of the construction safety is commonly dependent upon the statistical and historical information. since the existing systematic tool assisting to the effective decision making for estimating the safety prior to construction phase is inaccurate. In addition. it is true that there are the various difficulties to analyze and diagnosis the construction safety with the probabilistic approach. because there are the many vague factors and limited resources. Therefore. the purpose of this research is to provide the way to establish the efficient preventable countermeasure against the hazard factors. corresponding to the category of the hazard characteristic. by using non-structural fuzzy decision support system for diagnosing effectively the construction project safety.

박운용,곽두호,정성모,김천영 동아대학교 건설기술연구소 2001 硏究報告 Vol.25 No.1

The aim of our research is to find out how digital photogrammetry responds to image compression. Specially, we wish to know if using JPEG image compression leads to loss of accuracy in DTM derived by digital methods. We first review JPEG compression, and since we use the PCI OrthoEngine Airphoto Edition v6.3 digital phtogrammetry software, we briefly review it's principle of principle of operation. We use knowledge of the effect of JPEG compression on the geometric accuracy of images to predict the influence of compression on DTM accuracy. We then compare this to estimates derived from actual measurements. We find that the actual effect om DTM accuracy is greater than predicted, and consistent with geometric error due to compression in the region of 0.33 pixel.

This paper was presented an experimental study to analyze focal plane flux distributions produced by solar concentrating reflectors. Videographic flux mapping was used to investigate flux distributions in the focal plane located at the aperture of the cavity receiver. Peak fluxs in the focal region of 765.5 kW/m2 have been recorded, which corresponds to a concentration ratio of 1150 suns for 663 W/m2 insolation and 90% mirror reflectivity. Total integrated power of 403 W was measured under focal flux distributions. As a result of the percent power within radius, approximately 90% of the incident radiation is intercepted by 0.037m radius.
