Previously, Gum Metal (Ti-24(Nb + Ta + V)-(Zr, Hf)-O (at%)) exhibiting an ultralow Young`s modulus, ultrahigh strength and super elasticity was developed by Saito et al., who proposed that three electronic magic numbers, an average electron/atom (e/a) ratio of 4.24, an average bond order (Bo) of about 2.87, and an average “d” electron-orbital energy level (Md) of about 2.45 eV, should be satisfied simultaneously to obtain such “super” properties. The purpose of this study was to find new alloy systems possessing those properties and to examine the effect of beta equivalent content ([Mo]eq) on Young`s moduli of new alloys having the same three electronic numbers mentioned above. It was found that not only three electronic numbers but also [Mo]eq should be considered to obtain a similar Young`s modulus and hardness with respect to the Gum Metal.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

Repellent efficacy of essential oils and plant extracts against Tribolium castaneum and Plodia interpunctella

Lee Hwa‐Eun,Hong Su Jung,Hasan Najmul,Baek Eun Joo,Kim Jun Tae,Kim Young‐Duk,Park Mi‐Kyung 한국곤충학회 2020 Entomological Research Vol.50 No.9

This study was conducted to investigate the repellent efficacy of essential oils (Origanum vulgare, Pimpinella anisum, and Tanacetum cinerariifolium) and four plant extracts (Agastache rugosa, Capsicum annuum, Citrus reticulata, and Ginkgo biloba) against Tribolium castaneum (adults and larvae) and Plodia interpunctella (larvae). Gas chromatography/mass spectrometry analysis revealed the presence of carvacrol, anethole, and jasmolin I as the predominant constituent in O. vulgare, P. anisum, and T. cinerariifolium, respectively. Furthermore, ethyl hexopyranoside, 9,12‐octadecadienoic acid, cyclopentanol, and 2‐cresol were identified in A. rugosa, C. annuum, C. reticulata, and G. biloba, respectively. The repellent efficacy of each essential oil, plant extract, and the combination of oils was evaluated using a specially designed cylinder trap for 120 h. Among the three oils, O. vulgare and T. cinerariifolium had greatest repellent efficacy against P. interpunctella larvae. T. cinerariifolium exhibited effective repellence against the adults and larvae of T. castaneum. Therefore, O. vulgare (O) and T. cinerariifolium (T) were selected for further investigation of combined effects. Two essential oils were mixed in three different ratios of OT1 (1:3), OT2 (1:1), and OT3 (3:1). The repellent efficacies of OT1 and OT2 against the adults of T. castaneum were significantly greater than that of OT3. OT1 was effective against the larvae of T. castaneum, whereas OT2 was effective against the larvae of P. interpunctella. OT1 enhanced the repellent efficacy by approximately five times against larvae of T. castaneum, compared with that of T. cinerariifolium. Overall, OT1 was selected as the best repellent substance against all the tested insects.

트리플헬릭스가 해체될 때 산학협력 지속가능성의 조직생태학적 접근: 산학협력센터의 존폐 사례를 중심으로

홍은영(Hong, Eun-Young) 한국경영교육학회 2021 경영교육연구 Vol.36 No.1

[연구목적] 정부-대학-산업계의 트리플헬릭스 모델은 다양한 형태의 변화를 통해 서로간의 성장을 촉진하고 상호 발전할 수 있는 방안을 제도화하여 모델의 정당성을 확보하였다. 이 모델을 통해 20여년이상 구축된 산학협력생태계는 조직의 밀도의존성을 높였으나, 정부지원이 종료되는 등의 환경변화에 따른 조직의 사멸률 또한 증가하는 결과를 낳았다. 그럼에도 불구하고, 생태계에서 살아남는 조직이 존재하였고 그 요인을 밝히고자 하는 것이 이 연구의 목적이다. [연구방법] 연구를 위해 트리플헬릭스, 지속가능성, 조직생태학에 관한 이론들과 미국의 센터 운영 성공 및 실패사례 등을 충분히 검토하였다. 이후, 한국의 정부 지원이 종료된 산학협력센터를 대상으로 산학협력의 지속가능성을 조직생태학적 관점으로 접근하여 적소, 변이, 선택, 보존의 요인을 추출하였다. [연구결과] 결론적으로, 트리플헬릭스가 해체될 때 산학협력생태계의 지속가능 요인으로 산학협력코디네이터 등 핵심인력의 리더십과 전문성, 지역산업 특화발굴전략, 네트워크 폭의 다양성과 지속성, 기관의 지원의지가 필요함을 밝힌다. [연구의 시사점] 본 연구는 산학협력 핵심조직과 장기간 구축된 네트워크가 해체되지 않고 효과적으로 활용되도록 정부의 제도적 뒷받침이 전제되어야 함을 시사한다. 또한, 그동안 주로 연구되어 온 산학협력 체제, 과정, 성과 등의 연구에 비해 상대적으로 부족한 지속가능성, 생태계 관련 연구에 이론적 기여가 있기를 기대한다. [Purpose] The industry-academic cooperation ecosystem built for more than 20 years through the government-university-industrial triple-helix model increased organizational density dependence, but also resulted in an increase in organizational mortality due to environmental changes such as the end of government support. Nevertheless, there were organizations that survived the ecosystem, and the purpose of this study is to clarify the factors. [Methodology] For the study, the sustainability of industry-university cooperation was approached from the perspective of organizational ecology, targeting the industry-academic cooperation centers for which Korean government support was terminated, and the factors of niche, variation, selection, and retention were extracted. [Findings] In conclusion, it is revealed that the leadership and expertise of key personnel, specialized discovery strategies, diversity and continuity of the network width, and the willingness to support institutions are necessary as the sustainable factors of the industry university cooperation ecosystem. [Implications] This study is expected to make a theoretical contribution to research related to sustainability and ecosystem, which is relatively insufficient compared to research on industry-academic cooperation systems, processes, and achievements that have been mainly studied.

Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome, typically characterized by multiple colorectal adenomas and increased incidence of colorectal carcinomas if it is not treated. Moreover, a variety of extracolonic manifestation are seen. The prevalence of thyroid tumors developing in patients with FAP is about 1∼2%. Generally, papillary thyroid cancer indicates low mortality but ,however, as people get older, the cancer becomes more aggressive. So, the operation is required. Recently we experienced a case of FAP, presenting with papillary thyroid carcinoma, and reported with a brief review of literatures.

Thermomicrobium roseum 유래 Alcohol Dehydrogenase의 정제 및 특성

윤석영,홍민표,김은호,공광훈 중앙대학교 기초과학연구소 2000 基礎科學硏究所 論文集 Vol.14 No.-

Alcohol dehydrogenase from Thermomicrobium roseum was purified to electrophoretic homogeneity approximately 77-fold with a 38% activity yield by adenosine 5'-monophosphate and Mono Q column chromatography. The molecular weight of the enzyme was determined to be approximately 43,000 by SDS-polyacrylamide gel electrophoresis and 88,000 by gel chromatography, indicating a homodimeric structure. The Km and Vmax values of the enzyme for ethanol were 24.2 mM and 12.8 ㎛ol/min/mg, respectively. Pyrazole notably inhibited the enzymatic activity. Ca2+ ion activated the enzyme activity, but Cu2+ inhibited. The activity of the enzyme was optimal at pH 10.0 and 60℃.

은홍배,정영철,Zhang,Wei-xi,Li,Bing 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.2

연구목적과 방법 : 한국과 중국 대학생들의 음주문화를 비교하기 위해 이에 적합한 질문지가 개발되었고 1997년 11월부터 1998년 4월까지 한국 대학생 244명과 중국 대학생 220명을 대상으로 설문조사가 시행되었다. 이때 문제음주자를 가려내기 위한 NAST도 동시에 시행이 되었다. 결 과 : 1) NAST에 의해 가려진 문제음주자의 수는 한국이 39명, 중국이 20명이었으며 이들은 분석자료에서 제외되었다. 2) 한국학생의 음주률은 94.1%로서 중국의 62.6%보다 매우 높았으며 음주빈도도 한국이 중국에 비해 많은 편이었다. 양국 모두 가장 많이 마시는 술은 맥주였고, 음주장소는 한국은 호프집, 중국은 가정이 선호되었다. 중국도 일부(18.7%)에서 수작을 하는 것으로 확인되었으며 수작, 자작, 첨잔에 대한 견해가 양국간 현격한 차이가 있었다. 3) 정서적 음주동기 및 알코올 자체의 효과를 기대하는 음주동기에 있어서 양국 모두 부정적인 태도를 보였고 사교적 음주동기에 있어서는 한국은 긍적적 그리고 중국은 중립적 태도를 보였다. 4) 음주행동에 있어 공통점은 양국 모두 자율적이며 절제적인 것이었으며 차이점은 한국은 음주예절을, 중국은 술을 마시는 목적을 중요시하고 집단결속적 음주행동이 한국의 경우 보다 강조된다는 점이었다. 5) 음주인식에 있어서 술의 효용성을 예찬하는 것에 대해서는 양국 모두 부정적이었고 술에 대한 사회적 규제의 필요성에 대해서는 양국 모두 긍정적 입장을, 그리고 주정에 대한 관용도에 있어서는 양국 모두 호의적인 태도를 보였다. 결 론 : 이상의 결과는 한·중 대학의 음주문화가 공히 전반적으로 건강하며 양호한 상태에 있다는 점에서는 같지만 양국의 경제적 문화적 차이에 의해 기인된 것일 수 있는 일부 음주행동 및 음주인식에 있어서는 많은 차이가 있음을 말해준다. Objectives & Methods : To compare a drinking culture between Korean and Chinese University students, an appropriate questionnaire was developed and surveyed to 244 Korean students and 220 Chinese students with a co-administration of NAST to rule out problem drinkers from November 1997 to April 1998. Results : 1) The numbers of problem drinker detected by NAST were 39 for Korean students and 20 for Chinese students. They were all excluded in the analysis. 2) Drinking rate for Korean students was 94.1%, much higher than that of Chinese , 62.6% and drinking frequency was also higher in Koreans The most preferred alcoholic liquor was beer for both countries and the most preferred place for drinking was beer house for Korean and home for Chinese. Su-Jack(passing one's own glass to other people) was also found to be practiced among small percentage of Chinese students, 18.7%. 3) As for the drinking motivations, emotional one and expectation for the alcoholic effect itself were negative for both countries. However, social one was strong for Korean and neutral for Chinese. 4) As for the drinking behaviors, both countries showed autonomous and abstinent behavior : drinking manner and group solidarity were counted more importantly by Korean while objectives of drinking was considered more importantly by Chinese. 5) As for the drinking perceptions, both countries showed a negative attitude toward admiration of alcoholic usefulness but positive attitude toward the need for social regulation of alcohol and generosity toward a drunken behavior. Conclusion : These results show that drinking culture of Korean and Chinese University students is the same in terms of autonomous and abstinent behavior but quite different in terms of certain other drinking behavior and perception which might be related to their economical and cultural difference.
