Background : In recent years, gonorrhea has been pandemic and remains one of the most common 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 Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.

목적 : 경피적 관동맥 중재술은 최근 양적 및 질적으로 급격한 발전을 보였지만 시술 시 천자부위의 혈관 합병증은 아직 해결해야 할 문제점이다. 저자들은 대퇴동맥을 통한 경피적 관동맥 중재술을 환자에게 천자부위 지혈을 위한 혈관폐쇄기구인 안지오실의 안전성과 유용성을 고식적인 용수 압박법과 비교 연구하고자 하였다. 방법 : 2002년 4월부터 2003년 5월 사이에 삼성서울병원 심장혈관센터에서 대퇴동맥을 통한 경피적 관동맥 중재술을 성공적으로 시행한 200명의 환자(안지오실 사용군: A군, 100명, 고식적 용수압박법 사용군 B군, 100명)를 대상으로 시술 후 주요 합병증 및 경한 합병증, 지혈 후 환자가 자리에 앉기까지의 시간, 보행개시 가능시간, 총 재원 기간과 시술 1주 후의 합병증을 전향적으로 조사하여 비교 연구하였다. 결론 : 두 군에서 연령, 성별, 기저질환, 심혈관 질환의 위험요소, 시술의 종류, 시술 중 사용한 헤파린의 양, clopidogrel의 양, ticlopidine의 양, 지혈 시 수축기와 확장기혈압, ACT (activated clotting time)는 차이가 없었다. A군이 B군에 비해 시술 후 자리에 앉기까지의 시간 (A군: 4.3±0.3시간, B군: 13.7±0.8시간, p=0.004) 및 보행개시까지의 시간(A군: 6.8±0.5시간, B군: 18.8±2.1시간, p=0.013)이 유의하게 짧았다. 시술 후 주요 합병증은 두군 모두에서 관찰되지 않았으며, 경한 합병증의 전체발생은 A군에서 유의하게 적었다(A군: 28명, B군: 19명, p=0.003). 반상출혈의 경우는 A군에서 유의하게 낮았지만(A군: 3명, B군: 12명, p=0.01), 혈종, 출혈의 발생은 두군간에 차이가 없었다. 총 재원기간에는 두 군간에 차이가 없었다(p=0.239). 시술 1주 후 경과관찰에서 주요합병증은 역시 두 군 모두에서 관찰되지 않았으며, 경한 합병증의 전체발생은 두 군에서 차이가 없었다(A군: 15명, B군: 13명 p=0.418), 반상출혈의 빈도는 차이가 없었지만 혈종의 발생은 A군에서 더 낮았다(A군: 2명, B군:6명, p=0.004). 두 군 모두에서 출혈은 발생하지 않았다. 결론 : 대퇴동맥을 통한 경피적 관동맥 중재술을 시행한 환자에서 안지오실의 사용은 고식적 용수 압박법에 비해 환자의 침상 안정시간을 줄여 조기 활동개시가 가능하게 하였으며 국소합병증의 위험도를 일부 낮추어, 시술에 따른 환자의 불편을 현저하게 감소시킬 수 있다고 할 수 있을 것으로 기대된다. Background : Although the number and the quality of percutaneous coronary intervention have been recently increased dramatically, the vascular complication at puncture site is still the major cause of patients' morbidity. We evaluated the safety and efficacy of newly of newly-developed collagen-based arterial closure device, Angioseal after transfemoral percuatenous coronary intervention. Methods : This study was designed as a prospective single center non-randomized comparative study. A total 200 patients undergoing transfemoral percutaneous coronary intervention were enrolled between April 2002 and May 2003. They were divided into two groups; Angioseal group (group A, n=100) and manual compression group (group B, n=100). The baseline clinical and angiographic characteristics were reviewed. The time to sit up, the time to ambulation, the duration of hospital stay, major and minor vascular puncture site complications were monitored. The patients were followed-up for 1 week after procedure by telephone. Results : The baseline clinical characteriwtics, clinical diagnosis, cardiocascular risk factors, typesof procedure, doses and numbers of anticoagulants were similar between two groups. The blood pressure and activated clotting time were also similar. The time to sit up (group A: 4.3±0.3 hours, group B: 13.7±0.8 hours, p=0.004) and the time to ambulation (group A: 6.8±0.5 hours, group B: 18.8±2.1 hours, p=0.013) were shorter in group A. No major vascular complications were noted. The incidence of hematoma and bleeding were not significantly different between two groups. The incidence of ecchymosis, however, was significantly lower in group A (group A:12%, group B: 3%, p=0.001) The duration of gospital stay was similar between groups. During 7 days of follow-up period incidence of hematoma was significantly lower in group A (p=0.004). Although the incidence of ecchymosis was not significantly different between two groups. Conclusion : The angioseal may be associated with earlier ambulation and less patients' morbidity with low incidence of local complication rate compared to manual compression after transfemoral percutaneous coronary intervention.

In order to investigate the microstructure and mechanical properties on Al–25Cr–5Si (at%) alloy, a mixed powder with pureelements and an alloy powder using a gas atomization process were used. Fine and high purity Al–25Cr–5Si (at%) alloypowder was successfully prepared by gas atomization and densified using a spark plasma sintering (SPS) process. The overallpowder size distribution of the mixed Al, Cr, and Si elemental powders was in the range of 10–15 μm. The atomized Al–Cr–Sialloy powder was fine and spherical in morphology and difficult to be formed by intermetallic formation. Densification wasclearly confirmed at 1000 °C, with almost isolated pores formed, by clear removal of pores between particles, deformationof particles, an increase in the number of contacts, and a change in size between particles. As a result of XRD analysis ofthe sintered compacts, single phase was observed using the mixed powder, but the compact using gas atomization remainedthe alloy phase even at the process temperature. The Vickers hardness of the compacts by mixed powder was observed at59.70 Hv and the compact using gas atomized powders on the temperature 1000 °C of the Vickers hardness increased to702.6 Hv. The compressive yield strength of the compact with mixed powder was 195.24 MPa and the compressive strengthof the compact with gas atomized powder increased to 802.07 MPa. It is considered not to be decomposed by the AlCrSi,Al13Cr4Si4and Al8Cr5phases sintering process, resulting from the improvement of mechanical properties.

In addition to the development of functional cosmetics, technology to increase percutaneous absorption rate when applied to the skin is an important task. In this experiment, oleic acid was used as a skin absorption promoter, and its effect on transdermal permeability of adenosine was studied and analyzed using a skin-like membrane. As a result of the experiment, it was investigated that the permeability coefficient and concentration of adenosine are proportional to the content of oleic acid. This indicates that a high proportion of oleic acid is effective as a skin absorption promoter.

韓國傳承童謠에 드러난 靑少年의 意識

玄容駿,金榮敦 제주대학교 1980 논문집 Vol.12 No.1

1.0. 오늘날 靑少年들의 문제는 世界性을 띠고 있다. 한국의 경우에는 특히 요마적 2,30년 사이 近代化 기간의 단축으로 말미암은 逆機能이 크고 正體危機의 심각성이 따른다. 1.1. 그 正體危機를 극복하기 위해서는 韓國靑少年文化의 定立이 시급하며, 그 한 방법으로 文化遺産의 하나인 전승동요를 이용할 수 있을 것이다. 1.2. 다만, 그 수집연구가 여태껏 본격화되지 못했으므로, 이런 계제에 한국전승등요에 드러난 靑少年의 意識分析作業을 試圖함을 그 작업의 한계를 스스로 안게 마련이다. 1.3. 韓國傳承童謠에 드러난 靑少年의 의식을 밝히는 방법은 갖가지이겠지만, 그 가운데서 題材別 分析과 그 主題에 드러난 두드러진 의식을 밝히는 데 역점을 두려 한다. 2.0. 韓國傳承童謠에 담긴 意識을 살피기 위한 한 방법으로 몇 분의 전승동요 분류안을 참고 하면서, 그 題材分析을 試圖해 볼 수 있다. 2.1. 金素雲·任東權·박두진의 分類案을 참고하면서, 필자는 한국의 전승동요를 ① 動植物謠, ② 天體·氣象謠, ③ 遊戱謠, ④ 諷笑謠, ⑤ 語戱謠, ⑥ 자장가, ⑦ 其他謠로 나누는 게 우선 무난할 듯하다는 확신이 섰다. 2.2. 動植物謠와 天體氣象謠는 다같이 자연을 노래했다는 면에서 自然謠라 볼 수 있고, 어 린이들은 이 自然謠를 즐겨 부르며 노는 사이에 道와 德과 秩序를 배운다. 2.3. 또한 諷笑謠와 語戱謠는 일종의 말놀이이므로, 넓은 뜻으로는 遊戱謠에 포괄된다. 自然謠(動植物謠 天體氣象謠) 역시 어린이들의 靜的, 動的인 한갖 놀이로 불러지므로, 傳承童謠의 主宗은 遊戱謠라 말할 수 있다 2.4. 따라서, 한국의 전승등요는 자연을 무대로 하거나, 집단적 놀이 그 자체를 위한 遊戱謠라고 말할 수 있다. 3.0. 민요처럼 두렷하지는 않지마는, 몇몇 동요집등에 수록된 동요를 살피다 보면, 동요에서도 여러 패턴의 의식을 간추려낼 수 있다. 동요에 드러난 청소년의 의식 가운데 두드러진 바는 ① 隣助協同意識, ② 同類意識, ③樂天的 生活意慾, ④ 水平的 民主意識, ⑤ 秩序意識과 더불어, ⑥ 아름다운 꿈과 ⑦ 깊은 愛情등을 내세울 수 있다. 3.1. 어린이들은 傳來的 韓國社會에서의 친족과 이웃끼리의 協扶意識을 고스란히 받아들인 채 동요로 쏟고 있다. 서로 돕고 괴로움을 서로 나누는 내용의 사설을 즐겁게 노래하며 集團的인 놀이를 되풀이하는 가운데, 사회에 적응하는 능력을 기름으로써 寬容化, 協同化의 정신을 배운다. 3.2. 전승동요에 보면, 또한 同類意識이 꽤 드러난다. 많은 노래의 내용에서도 살필 수 있거니와, 四足獸를 제재하기보다, 자그만 동물을 노래하는 경향이 많음도 또한 同類意識에 근거함인 줄 안다. 3.3. 또한 한국의 전승동요에는 樂天的 快朗性이 두드러지게 드러난다 이 樂天性은 세게 모든 어린이들의 일반적 성향이겠지마는, 한국 전승동요의 경우에는 그 快朗催에 멋이 깃들어있다. 3.4. 어린이들은 民主主義의 信奉者다. 水平的 民主意識이 짙게 깔렸는가 하면, 「類同의 引力」(the attraction of likes)에 따른 交友 또한 민주주의에 터전한 것이다. 3.5. 한국의 어린이들은 벗들과 어울리며 뛰놀면서 道德的 規準과 集團的 思考를 배우며 익히는 가운데, 生活秩序를 짙게 터득해 간다. 3.6. 전승등요 가운데는 곱고 소담스러운 꿈이 흐른다. 어린이들에게 주어지는 꿈은 관념적이요, 허황한 게 아니라, 우선은 비록 자그맣더라도 일상적, 구체적인 것이다. 3.7. 또한 전승동요에는 父母兄第 특히 母情으로부터 출발하여 벗과 이웃으로 擴散되는 따스한 愛情이 넘친다. 1.0. Today, the problems of youth are a worldwide issue. In the case of Korea, its rapid modernization during the past 20 or 30 years has had harmful side effects, resulting in crises that are typical in a modernizing society. 1.1. To overcome the such crises, Korea's youth culture must be integrated into society as soon as possible. we can utilize orally-handed-down children's songs one of our cultural inheritances, as a method to overcome these crises. 1.2. Since orally-handed-down children's songs has not yet been collected and studied on a scale, there are limits to this attempt to analyze Korean youths' attitudes in the structure of Korean oral folktales. 1.3. There are various ways to analyzing youths's attitudes in Korean orally-handed down children's songs. This essay will put emphasis on analyzing folktale materials and on disclosing youths's attitudes in the themes of these tales. 2.0. By consulting several classification schemes of Korean orally-handed-down children's songs materials can be analyzed as one method of studying the structure of attitudes in Korean orally-handed-down children's songs. 2.1. In regard to Kim So-woon' s, Im Dong-kwon's and Park Doo-jin's classification schemes, Korean orally-handed-down children's songs are divided into seven parts, including the following: 1. Songs of animal & plants, 2. songs of the celestial sphere & atmospheric phenomena, 3. songs of merrymaking, 4. songs of satire, 5, songs of language, 6, cradlesongs, 7. others. 2.2. songs of animal & plants, and of the celestial sphere & atmospheric phenomena, can be said to be "songs of nature" since the two songs celebrate nature. Children learn morality, virtue and public order in the course of enjoying themselves while singing the "songs of nature". 2.3. The songs of satire and language are "language songs" of a sort. Therefore, broadly speaking, they refer to merrymaking. Since songs of nature (songs of animal & plants, and of the celestial sphere) are dynamic and static song·s for children, the main songs of Korean orally-handed-down can be said to be songs of satire. 2.4. Therefore, most of Korean orally·-handed-down children's songs are songs of nature, or songs of merrymaking 3.0. Though orally-handed-down children's in the category of nursery rhymes are not as clear as songs, youths's attitudes in orally-handed-down children's can to divided into several patterns. The most striking patterns of youths' attitudes are here: 1. attitudes of cooperation, 2. attitudes of same sort, 3. attitudes of optimistic life, 4. attitudes of liberal democracy. 5. attitudes of public order, 6. attitudes of beautiful dreams, 7 attitudes of deep love. 3.1. Children learn and enjoy their songs while learning attitudes of cooperation front their family and from neighbors. They also learn the sprit of generosity by developing their contribution to society in the course of singing songs of joys and sorrows, and while living ill a group. 3.2. Attitudes of same sort are often presented in the orally-handed-down children's songs and in the many songs. Notably, regarding attitudes of same sort, most of the songs were not about big, four-legged animals, but about small animals. 3.3. An optimistic cheerfulness is remarkly present in Korean orally-handed-down children's songs The cheerfulness is typical of a child's inclination toward the world. In addition, Korean orally-handed-down children's songs characteristically reflects zest in addition to cheerfulness. 3.4. Children are devotees of democracy. They are attracted to equality as well as the haying attitudes of liberal democracy. 3.5. Korean children learn the conventions of social life in the course of familiarizing themselves with the moral canons and the thought manners of their peer group. 3.6. There are beautiful and attractive dreams in the orally-handed-down children's songs Children's dreams are not ideological and unreliable, but substantial and actual even when they are small in scale. 3.7. Finally, in Korean orally-handed-down children's songs, there is evidence of affection spreading to friends and neighbor from parents, affection between brothers and sisters, and especially of a mother's devotion.
