Objective: The purpose of this study was to compare preceptors and new graduate nurses on their perception of preceptor teaching effectiveness. Methods: The participants were 90 new nurses and 90 preceptors who worked in A medical center. The data were collected from July 1 to September 30, 2008. A cross-sectional descriptive survey was done using a structured questionnaire. Results: New nurses' perception (4.07±.44) of the preceptor teaching effectiveness was significantly higher than perception of the preceptors (3.57±.37). Fifty five percent of new graduate nurses reported a lack of coherence in the preceptor's practice guidelines. For 5 causal factors classified on the teaching effectiveness, the factor of 'Professional knowledge and ability' showed the highest score, but 'Interpersonal and communication skill' got lowest score for both group. Preceptors responded that they did not have enough time to teach well because of their heavy workloads. Conclusions: These results suggest that the preceptors need appropriate compensation and education opportunities, and new graduate nurses need consistent education by the teaching professionals. Therefore, it is important to give preceptors full charge of the preceptorship. Also, it will be necessary to develop education programs to enhance interpersonal and communication skill for preceptors and new nurses.

This study focuses on the characteristics of communication by such social network service (SNS) as Twitter and Facebook. In order to achieve the goal of this study, interview to students in Seoul Women's University was introduced to figure out such communicative behavior using SNS as frequency, motivation, purposes, and effects of SNS. The interview results show that students in Seoul Women's University have strong desire to communicate each other and SNS is one of digital mechanism to enhance their communication. Also, the results point out that interviewees communicative behavior using SNS can be categorized into two types of communication, network- oriented communication to promote friendship and fact-oriented communication to collect and share information. Moreover, interviewees indicate that SNS has both positive and negative (for example, privacy and security, time-consuming, false information, and addiction) aspects, as a results, users' self-control and digital competency should be improved. 소통은 인간 사회의 핵심 가운데 하나이다. 인간은 다른 사람들과 소통하고 싶어 한다. 즉, 상대방에 대해 알고 싶어 하는 동시에 자신을 알리고 싶어 하는 욕구를 가지고 있다. 인간의 소통에 대한 욕구를 충족시키는 방법은 시대의 발전에 따라 변화해왔다. 수천년 전부터 인류는 직접 만나서 언어로서 서로의 감정을 표현하고 정보를 교환하며 지내왔다. 즉, 이 시기에는 소통에서의 시간적․공간적 제약이 존재하였다. 그러나, 문자와 종이가 발명되면서 인류는 소통에서의 시간적․공간적 제약을 극복하기 시작하였다. 인류의 소통은 전화의 발명으로 한발 더 나아가게 되었으며, 디지털 혁명은 인간에게 시간적․공간적 제약을 뛰어넘는 소통을 가능하게 해 주었다. Bill Gates가 “PC는 인간이 만든 도구 중 인간에게 가장 많은 권한을 부여하는 도구라고 자신있게 말할 수 있다. PC는 소통의 도구, 창의력의 도구이며 사용자가 직접 만들어 나갈 수 있다(I think it's fair to say that personal computers have become the most empowering tool we've ever created. They're tools of communication, they're tools of creativity, and they can be shaped by their user.)”라고 주장한 바와 같이, PC와 인터넷의 급속한 발전으로 시발된 디지털 혁명은 인간의 소통에도 20세기 후반에는 상상도 할 수 없었던 큰 변화를 가져왔다. 소위 제 3의 물결(Toeffler, 1980)이라 불리는 정보화 시대의 물결을 타고 현대인들의 소통에 대한 욕구를 더욱 더 편리하게 발현 할 수 있도록 하는 수단의 변화를 가져왔다. 현 시대의 사람들이 행하는 소통의 행태는 전통적인 소통의 방법과 디지털 네트워크의 소통방법이 함께 어우러져 행해지는 모습을 보이고 있고, 이와 더불어 인터넷 등을 통한 가상 커뮤니케이션의 방법으로도 이루어지고 있다. 그리고 디지털 네트워크 기술 발전에 따른 해당 시스템의 이용자가 증가하고 있으며, 관련 시스템이나 모바일 어플리케이션도 지속적으로 개발되어 유통되고 있다. 이러한 디지털 네트워크 발전 속에서 Social Network Service(이하 SNS)가 새롭게 등장했다. 정보기기와 해당 시스템의 발전으로, 면대면 형식의 소통을 벗어나 SNS를 통한 온라인상의 소통이 가능하게 되었고, 이는 다른 소통의 방법보다 상대적으로 편리함을 제공하여 SNS 이용자들에게 폭발적인 반응을 불러일으켰다. 2010년 초 미국에서 처음 쓰이기 시작한 신조어로 ‘TGIF’가 있다. ‘TGIF’는 트위터, 구글, 아이폰, 페이스북 등 스마트 열풍의 진원지라 할 수 있는 네 가지 서비스를 통칭하는 표현이다. TGIF가 급속히 확산된 지난 2년간 세계인들은 정치․경제․사회․문화 모든 면에서 큰 변화를 겪었다. 2008년 당선된 미국의 오바마 대통령은 세계 최초의 트위터 대통령이라 할만하며, 2011년 초에 발생한 튀니지의 ‘재스민 혁명’과 이집트의 ‘키파야 혁명’ 또한 ‘TGIF’의 소산이었다. 오바마 대통령의 당선 이후 유튜브 정치(YouTube Politics)란 용어가 탄생하였고, 2011년 1월 26일 미국 오바마 대통령의 연두교서는 유튜브를 통해 세계에 생중계 되었다. 이러한 정치 분야에서의 소통 뿐만 아니라 기업이 직접 SNS계정을 만들어 네트워크상에서 자신의 고객과의 소통을 하는 기업이라는 조직 대 개인의 소통도 증가하고 있다. KT나 삼성 등의 대기업 등은 SNS를 이용한 고객과의 소통을 통해 기업이미지 제고와 고객과의 친밀함을 시도하고 있는 것은 이미 주위에서 많이 볼 수 있다.

종합 건강진단을 실시한 정상성인에서의 혈청지질 분포에 관한 연구

박일환,유선미,정유석 단국대학교 1997 論文集 Vol.31 No.-

Background: Hypercholesterolemia and dyslipidemia are regarded as the risk factors of atherosclerosis of the coronary arteries. The purpose of this study is to measure the serum lipid levels of the normal persons and to calculate the cut-off values of serum lipid levels to predict the occurence of coronary events. Methods: We investigated the serum lipid profiles of the normal adults who had visited the health promotion center of Dankook University Hospital. The mean values of serum lipids were evaluated according to the groups of age, we calculated the percentile values of serum total choleterol. Results: In normal adult persons, the means of total cholesterol increased according to age. The cut-off values of serum total cholesterol for the risk of atherosclerotic coronary events were 189 ㎎/dl for the moderate risk group(75∼90 percentile of normal persons) and 225 ㎎/dl for the high risk group(over 90 percentile of normal persons). Conclusions: This study shows that the mean and the cut-off values of serum lipid in the persons who are not obese and have normal blood pressure are significantly lower than those values of normal Korean adult persons.

다중 쓰레드 기반의 병렬처리서버용 안티바이러스 엔진

악성코드에 대한 보다 바람직한 예방은 클라이언트측이 아닌 서버측에서 이루어지는 것이다. 본 논문에서는 새로운 개념 의 서버용 안티바이러스 엔진인 SAVE 1.0을 설계 구현하여 제시한다. SAVE는 기본적으로 1개의 AV모니터와 다수의 AV에이전트로 구성되어 있는데 다중 CPU를 장착한 병렬처리서버의 특징을 직접 활용하기 위하여 관리자가 다중쓰레드 기법을 직접 지정할 수 있도록 하고 있다 악성코드를 5가지 부류로 구분하여 바이러스 시그너쳐 DB를 구축 제공함으로써 부류별 진단을 지정할 수 있도록 하고 있으며 실시간 네트워크 패킷 검사를 통한 악성코드 유입 점검 기능도 제공한다. 웹 기반의 관리자 인터페이스는 뛰어난 사용자 편의성을 제공하고 있다. 성능실험결과 악성코드 검색율은 국내외 상용제품과 비교해서 매우 우수한 것으로 나타났으며 검색속도에 있어서도 서버의 CPU 수 증가에 거의 선형 비례하여 향상되는 특징을 보이고 있다. It is more desirable to prevent and detect the malicious codes in server system rather than in client PCs. In this paper, we suggest a new anti-virus engine, SAVE 1.0, which is executed on a parallel processing server. SAVE consists of 1 AV monitor and several AV agents. A system administrator can control the degree of multi-thread directly in order to enhance the utilization of parallel processing servers. Virus signature DBs in SAVE are classified into 5 categories, which support system administrator's options to use the classifier or not. By real-time checking of network packets, the influx of malicious codes can be prevented. Web-based GUI is one of the convenient functions provided in SAVE. In performance tests, we have confirmed that SAVE has higher virus detection ratio than any other AV engine, and SAVE has a desirable feature as an software of parallel processing servers since the performance of SAVE is improved almost linearly as the CPUs in a parallel processing server increases.

朴유미 東亞大學校 1982 東亞論叢 Vol.19 No.1

The monomer reactivity ratios determined at 70℃ for free radical copolymerization of N-vinylacetamide and acrylic acid are: r₁(N-vinylacetamide)=0.05 r₂(acrylic acid)=3.49 The values of Alfrey-Price's Q and e for N-vinylacetamide were found to be 0.12 and -0.51, respectively. The statistical analysis for the monomer sequence distribution and the mean sequence length shows that the copolymers formed from this monomer pair are composed of short blocks of N-vinylacetamide and long blocks of acrylic acid.

합성 수화겔막에서 용질들의 분배특성

박유미 東亞大學校 大學院 1987 大學院論文集 Vol.12 No.-

Hydrogel menbranes were prepared by copolymerizing 2-hydroxyethylmethacrylate with acrylamide, N,N-dimethylacrylamide, and methylmethacrylate in presence of the solvent and the crosslinker ethyleneglycol dimethacrylate. Using the membranes, the equilibrium water content and partition coefficient for urea, N, N-dimethylurea, thiourea, and acetamide were measured. The partition coefficient data show that the apolar pendant group and polymer matrix. In the water content system, it is known that the partition of solutes were determind by hydrophobic interaction between solutes and apolar pendant group or polymer marix. Also in the gelsolute affinity, this experiment indicate that the apolar pendant group is more preferential part than polymer matrix. Urea is not interacted with hydrophilic and hydrophobic hydrogels. For all sort of hydrogels, the partition of urea occures only intothe water-containing regions, which are all interconnected.

The purpose of this study was to investigate the association among nutrient intakes and health-related lifestyles with cardiovascular disease risk assessed by blood lipid profile according to Apolipoprotein E genotypes. Middle-aged industrial male workers who had completed their annual medical examination were recruited and data of 675 subjects who finished the nutrient survey were used in the analysis. Anthropometric parameters, dietary assessment (FFQ), health-related lifestyles and blood profiles were used for statistical analyses. Apo E genotype groups were classified into the following three genotypes: Apo E2 group (including E2/E2, E2/E3, E2/E4), Apo E3 group (including E3/E3), Apo E4 group (including E3/E4, E4/E4). The frequency of Apo E2, E3, and E4 allele were 13.3%, 75.0% and 11.7% respectively. There were no significant differences in the anthropometric parameters depending on different Apo E genotypes. Also, no significant differences in the nutrient intakes were found according to the genotype groups. The nutrient intakes of all subjects were similar to or higher than the level of KDRIs (Dietary Reference Intakes For Koreans) except for intakes of calcium (67.44% of KDRIs), vitamin A (73.83% of KDRIs) and vitamin B2 (78.02% of KDRIs). Also, there were no significant differences of health-related lifestyles according to Apo E genotype groups. As for the lipid profiles, Apo E4 group had significantly higher total and LDL-cholesterol concentrations than the Apo E2 group (p < 0.05). We confirmed that plasma total and LDL-cholesterol concentrations were greatly influenced by Apo E genotypes. However, nutrient intakes and health-related lifestyles were not associated with Apo E genotypes.

The purpose of this study was to investigate the effect of muscular resistance training on abdominal fat. Subjects were composed of sixteen obese middle-aged women. Resistance training was performed 60minutes per day, 5days per week at 60% of 1RM during 1~12weeks and at 70% of 1RM during 13~24weeks. The items for abdominal fat volume were measured subcutaneous fat volume(SFV), visceral fat volume(VFV), VFV/SFV by computed tomography. Paired t-test was used to evaluate the difference of baseline and after 24 weeks muscular resistance training. The 0.05 level of significance was as critical level for the study. The results of this study are as follow; 1. Body weight and %fat were significantly(p<.05) decreased in muscular resistance training group. 2. VFV and SFV were significantly decreased in muscular resistance training group. 3. VFV/SFV was significantly decreased in muscular resistance training group. In conclusion, visceral fat and subcutaneous fat were decreased in muscular resistance training. So it is maybe thought that long-term muscular resistance training improved body composition for obesity treatment.
