Since the introduction of Western concept of nursing to Korea in late 1880s, Korean nursing practice has evolved into Korean culture. The purpose of this study was to explore and identify similarities and differences in hospital nursing practice between Korea and the United States using the grounded theory method. The data were gathered from 15 Korean nurses working in U.S. hospitals using semi-structured, in-depth interview method. Major similarities in nursing practice between Korea and U.S. existed in the 7 domains that Benner indicated in 1984. The nursing administration system was also similar in both countries. On the other hand, differences existed in how nurses execute these domains of nursing practice. These are the roles of nurses. nurse aides and family members. and the interpersonal relationships, and problem presentation and problem-solving strategies. American family members rarely participated in the patient's bedside nursing care, while Korean family members actively participated. American nurse aide participated in direct patient care, while Korean nurse aides did not. Also Korean nurses were participated more in administering and managiang the patient's diagnostic and treatment modalities, while American nurses foucused on the needs and demands of the patient. In terms of interpersonal relationships, American patients were more self-centered and demanding than Korean. American nurses focused more on the right of individuals while Korean nurses were more oriented to harmony with the coworkers. With inferiors and superiors, American members were more egalitarian, while Koreans tended to be hierachical. In ways of suggesting problems, American nurses tended to pick out the problems more frequently than Korean nurses did.. As to ways to solve the problems, American nurses relied heavily on explicit verbal explanations, while Korean nurses relied more on bodily action and behaviors. The results of this comparative study contribute to nursing by adding knowledge on the theory of culture care by describing the similarities and differences in nursing practice between Korea and the United States.

This research evaluated and analyzed the level of acceptability of spinach according to blanching time by testing consumer taste of corresponding countries for the purpose of globalizing Korean food. General taste, appearance, flavor, and texture of spinach blanched for 20 seconds were highly evaluated by Koreans and Japanese ($p$<0.05), who are used to the method of slightly blanching, mixing, and eating spinach. On the other hand, general taste, appearance, flavor, and texture of spinach blanched for 5 minutes was highly evaluated by the French ($p$<0.05), who are used to eating boiled spinach. Concerning the result of JAR, there were clear differences in hardness and boiling level according to country among spinach samples, even though they were blanched for the same time and mixed with the same spices. Koreans and Japanese evaluated that hardness and boiling level of spinach blanched for 20 seconds were proper, whereas the French evaluated that spinach scalded for 20 seconds was too raw and crispy. Under the same context, French consumers evaluated that hardness and boiling level of spinach blanched for 5 minutes was proper, whereas Koreans and Japanese evaluated that spinach blanched for 5 minutes was boiled too much. These results show that familiarity level is an important driver of affecting the preference levels for three kinds of spinach according to country.

일반적인 버스 아키텍처는 공용버스 내에 마스터와 슬레이브, 아비터, 디코더 등으로 구성되어 있다. 특히 여러 마스터들이 동시에 버스사용 권리를 받을 수 없으므로, 아비터가 공용버스와 마스터 사이에서 중재하는 역할을 수행한다. 중재 방식에는 fixed priority 방식, round-robin 방식, TDMA 방식, Lottery 방식 등이 연구되고 있는데, 중재방식에 따라 버스 사용의 효율성이 결정된다. 반면 버스 아키텍처를 수정하여 시스템의 성능을 극대화할 수 있는데, 본 논문에서는 병렬 데이터 통신을 지원하는 플라잉 마스터 버스 아키텍처를 제안하였고, 위에서 언급한 여러 가지 버스 중재 방식에 대하여 일반적인 공용버스와 비교하여 장단점을 분석하였다. TLM(Transaction Level Model)을 이용한 성능검증 결과로부터 버스 중재방식과 무관하게 약 40%의 성능이 향상되었음을 확인하였다. 플라잉 마스터 버스 아키텍처가 좀 더 연구되고 다양한 SoC에 적용되면서 고성능 버스 아키텍처로 자리매김할 것이다.

The purpose of this study was to observe the effect of eating a raw egg by professional or nonprofessional voice users on their voice quality and the duration of the effect. 20 professional voice users and 20 nonprofessional voice users participated in the experiment and they had gone through stroboscopy to have no vocal or laryngeal diseases. The voice exam was performed three times: before eating a raw egg (1st period), right after eating it (2nd period), and 10 minutes later (3rd period). By using Multi-dimensional Voice Program which is a software of Computerized Speech Lab 4500 as a voice analysis instrument, the authors checked the F0, Jitter, Shimmer, Noise to harmonic ratio (NHR), and Voice Range Profile (VRP). Results showed as follows: Firstly, vocal hygiene was good in 57.5% of the total subjects and was poor in 42.5%. 40% of professional voice users and 75% of nonprofessional voice users hand good quality. 77.5% of the total subjects had the vocal fatigue while 22.5% of the subjects did not. 95% of the professional voice users and 60% of nonprofessional voice users complained the vocal fatigue. 60% of the total subjects reported a subjective vocal symptom. 65.0% professional voice users and 70.0% of nonprofessional voice users reported a voice symptom. From the results above, we suggest that eating a raw egg may lead to imporve voice quality of the professional voice users.

The vision disturbances of school-age children has been recognized as and important school health problem. The purpose of this study is to describe the current status of the visual health and to explore the related factors for the decrease in visual acuity in the elementary school age children. The study subjects were 697 children (Boys: 338, Girls: 359) of 4th to 6th grade in two school in urban area. The visual acuity data of the school health examination in 1999 and 2000 were utilized for analysis. The questionnaire for children and parents was used for survey. The findings were as follows. 1. The prevalance rate of the children with the visual acuity less than 0.7 on the left eye were 26.84％ ( Grade 4), 31.30％ (Grade 5), and 38.39％ (Grade 6). The rate on the right eye were 28.31％ (Grade4), 30.37％ (Grade 5), and 37.92％ (Grade 6). There was a significant difference in the rate of the visual acuity less than 0.7 according to grade (p<.01). 2.The rate of visual acuity decrease was 40.12％. 3. The factors related to the decrease in the visual acuity were grade, sex, genetic factor, posture, and the awareness of the visual acuity. There was more decrease in the visual acuity when the children were in higher grade (O.R= 1.06), girls (O.R=2.29). Children having parents with better vision (Father: O.R=1.26; Mother O.R= 1.25) showed better vision. On the other hand, when the children have siblings with glasses, there was more decrease in the visual acuity (O.R=2.31). Students with good posture during study (sitting on the chair) and watching TV to the lower direction showed less decrease in the visual acuity. Also, when the students know their visual acuity, the rate of decrease were lower. The variables which odds ratio were statistically significant were sex (p<.01), siblings with glasses (p <.01), and awareness of visual acuity (p<.01).

This study performed to examine the genuineness of Kyung-Jong's poison hypothesis which was the one of the biggest topic in the history of Joseon Dynasty. Kyung-Jong's poison hypothesis is that Kyung-Jong who was the 20th king of the Joseon Dysansty was poisoned by the next king Young-Jo who became the 21st king. This theory was hyphosized by Sim-Yoohyun and was widely known in the 4th year of Young-jo through the revolt. Kyung-Jong suffered with severe diarrhea for 5 days which finally took his life away right after he had have marinated raw crab and persimmon. Some insist the poison must had been in those foods. However, the symptoms that Kyung-jong had were not matched with the poisons which used in those days and also poison was not the reasonable way of murder, so it is hard to say there is little possibility of poison. On the other hand, considering of Kyung-jong's health, marinated raw crab and persimmon could result of severe diarrhea. In the mean time, the possibility of Young-Jo's intention of killing Kyung-Jong is very low. Rather, he blame the royal doctors who scout the outside doctors, because he believed that it led Kyung-jong's death since the treatment was chaotic with all those different doctors. Even after the Kyung-Jong's death, Young-jo was always strict to scout the outside doctors and missed Kyung-jong consistently. On this basis, it is hard to say that king Kyung-Jong was murdered by poisoning.

In the Ki-Gu(氣口) pulse and the Yin-Yeong(人迎) pulse are the arterial pulsation position of the Lung Channel of Hand-Taeuem(手太陰) and the Stomach Channel of Foot-Yangmyeong(足陽明). At the pulses we can examine the circulation of Ki-Hyeol(氣血), the balance of Uem-Yang(陰陽), the deficiency and excess of the diseases, whether the disease is in Uem-Channel(陰經) or Yang-Channel (陽經), whether the disease is internel injury or externel injury. In the Ki-Gu(氣口) pulse and the Yin-Yeong(人迎) pulse are in front of the Right-Kwan(右關) and the Left-Kwan(左關) the distance of 1 Pun(分) because of completion of the Chon-Ku-Pulse-Taking(寸口脈診). The purpose of examnation is same to . In the Kwan-Pulse(關脈) doesn't have the position. It has only the role of a gateway of the circulation of Ki-Hyeol(氣血), the balance of Uem-Yang(陰陽). And it is same to role of the Ki-Gu(氣口) pulse and the Yin-Yeong(人迎) pulse in . So we can think that the Kwan-Pulse(關脈) in and the Ki-Gu(氣口) pulse and the Yin-Yeong(人迎) pulse in are the same thing. And we must have the different standard when examine the condition of Sam-Cho(三焦) and the circulation of Ki-Hyeol(氣血), the balance of Uem-Yang(陰陽) because the position of the Kwan-Pulse(關脈) came out after the time of .

BCI 기술은 생체신호인 뇌파를 수집하여 신호처리를 거친 후 실질적인 기기제어 및 통신 시스템 등을 제어하는 시스템 관련 기술이다. BCI 시스템 구현을 위해서는 뇌파의 특성을 실시간으로 분석하여 학습 시키고 학습된 뇌파의 특성을 적용하는 단계가 요구된다. 본 논문에서는 EEG 데이터를 효율적으로 분석하기 위해 점진적으로 갱신되는 주성분 분석을 이용하여 왼손/오른손 동작에 영향을 미치는 EEG 신호의 특징을 찾고, 이를 반영하여 데이터의 차원을 축소한다. 입력 자료의 특징을 충분히 포함하면서 낮은 차원을 가지는 데이터를 이용한다면 분류를 위한 계산량을 감소시킬 수 있을 뿐만 아니라 불필요한 특징을 제거함으로써 분류 성능을 향상 시킬 수 있다. 본 논문에서는 점진적으로 갱신되는 주성분 분석을 이용하여 데이터의 차원을 축소하고 이에 대한 효율성을 검증하기 위해 K-NN분류기를 이용하여 분류 정확도 측정을 수행하였다. 그 결과 주성분 분석을 이용하여 특징을 추출하고 분류율을 측정한 경우보다 평균 5% 높은 분류 정확율을 보였다.

In the present study, it was observed how the phage-host system that is naturally reproduced in activated sludge is affected by the host inoculation. The system of Microlunatus phosphovorus and its phages was selected as the phage-host system native to an activated sludge system operated for 19 days under sequencing anaerobic-aerobic conditions with glutamate as the main carbon source. The phage-host system related to M. phosphovorus was monitored by plaque assay for the phages and by fluorescent in situ hybridization (FISH) for the bacterial host. In addition, the whole phage structure was also monitored by pulsed-field gel electrophoresis (PFGE). During the first 9 days, the phage-host system was more or less steady at approx. 9% (FISH/ DAPI) for M. phosphovorus and approx. 10,000 PFU/ml for its lytic phages. Microlunatus phosphovorus JCM9379 was inoculated into the activated sludge on day 10. Right after the inoculation, M. phosphovorus was approx. 24% (FISH/DAPI) whereas its lytic phages dropped down to approx. 500 PFU/ ml. After the host inoculation (within 9 days), however, the phage-host system eventually reverted to its original level in each population. On the other hand, the whole phage structure was not significantly changed by M. phosphovorus inoculation but stable throughout the process operation. Only the minor change that four phage groups gradually became abundant after the host inoculation was observed.
