In the knowledge-based society which recognizes knowledge as a core value, knowledge management is one of the most interesting issues. The creation of knowledge within an organization occurs as a result of interactions of tacit and explicit knowledge, i

The aim of the present study was to determine the effect of proprioceptive neuromuscular facilitation (PNF) leg patterns on the muscle activation of neck flexors. Twenty healthy subjects participated in this study. Each subject performed bilateral asymmetrical PNF leg patterns against manual resistance under four conditions: through the full range of motion toward the right side, left side, and the end range in the right side, left side. Electromyographic (EMG) data was collected from the sternocleidomastoid (SCM) muscles as neck flexors. The root mean square (RMS) value of the SCM was measured and normalized from maximal EMG activity of the SCM. The data were analyzed using the paired t-test and repeated analysis of variance (ANOV A) was used to compare the statistical significance. The results of this study are summarized as follows: Firstly, the RMS values of SCM were significantly higher in all four PNF leg patterns than in the resting condition (p<.05). Secondly, there was no significant difference in muscle activation according to the direction of PNF leg patterns (p>.05). Thirdly, there was no significant difference in muscle activation according to the point of range of the motion of leg patterns (p>.05). It is suggested that PNF bilateral asymmetrical leg patterns have a considerable effect on muscle activation of the SCM, regardless of the range of motion and direction of PNF bilateral asymmetrical leg patterns.

저온, 광도 및 IBA 처리가 카네이션 삽수의 발근에 미치는 효과를 구명하기 위해 본 실험을 수행하였다. 삽수의 4oC 저장과 생장조절제 IBA를 조합한 처리효 과는 IBA 처리농도가 높을수록 근원기가 증가하였고, 4oC에서 6주와 IBA 400mg·L-1의 동시 처리구에서 초장, 뿌리수, 뿌리 생체중, 줄기 생체중 등이 월등히 좋았다. 저온과 생장조절제 동시 처리에서는 저온 2주 이상이면 발근수와 건물중에 효과가 나타나기 시작하 였고 저온처리 기간이 길수록 발근수와 건물중은 증가 하였다. IBA 400mg·L-1 처리 및 저온 저장기간별 카네이션 삽수의 삽목 후 시기별 뿌리수는 삽목 후 3 주 후면 충분히 확보되는 것으로 나타났다. 삽목상 온 도는 20oC 처리구에서 발근율이 89.7%로 가장 높았 고, 발근소요일수가 27.3일로 가장 짧았으며, 뿌리 길 이도 22.8mm로 가장 길었다. 광도는 높을수록 발근에 효과적이었으며 200μmol·m-2 · s-1 처리구에서 발근소요 일수 27.6일, 뿌리길이 24.3mm로 뿌리의 생육이 가장 양호하였다.

본 연구에서는 불과 함께 에스테르화 반응물 및 생성물 일부가 친수성 막을 투과하는 비완전 분리를 고려한 투과증발-촉진 에스테르화 반응모델을 확립하였으며, 이 모사모델에 막 분리 효율 및 물 제거능력을 설명하는 항들을 포함시킴으로써 막 투과분리가 에스테르화 반응에 어떻게 영향을 끼치는가를 공정모사를 통해서 체계적으로 살펴보았다. 모사결과 막을 통한 비완전 분리 즉, 분리막을 통한 반응물의 투과는 역반응을 유발시켜 전체 반응을 지연시키며 그 결과 반응 전 환율은 투과증발 공정을 사용하지 않은 반응보다는 높으나 물에 대한 완전한 투과선택도를 갖는 투과증발 공정을 사용하는 반응시스템보다는 낮음을 알 수가 있었다. 반응 시스템 내에서 장착된 막을 통한 투과로 인한 반응부피의 변화가 반응 속도에 끼치는 영향을 살펴보았는데 반응 초기에는 반응물 농축효과가 지배적이어서 반응을 촉진시키며, 반응이 진행되어 생성물이 형성됨에 따라 생성물 농축효과가 점점 중요해지고 이 효과가 반응의 속도를 감소시킴을 알 수가 있었다. 에스테르화 반응공정 중에 투과증발공정을 적용하는 시점에 따라 반응속도, 반응 전화율이 달라짐을 공정모사를 통해 관찰하였다. 반응 모델 식으로부터 분리막의 성능과 반응 인자들 간의 상관관계는 확립하고 이 상관관계를 주어진 막 분리능력 하에서 반응 인자 조건 설정, 혹은 주어진 반응조건 하에서 막 분리능력을 설계하는 도구로 사용할 수 있다.

The purpose of this study was to examine inter- and intra-examiner reliability of the sacroiliac joint (SIJ) anatomical landmarks palpation. Two physical therapists and one doctor specializing in rehabilitation examined 22 asymptomatic subjects. They examined anterior superior iliac supine (ASIS), posterior superior iliac supine (PSIS) and iliac crest (IC). For the assessment of intra-examiner reliability, 3 examiners repeated the measurements 3 times over a 2-week interval. Kappa (Kg) yielded intra-examiner reliability that ranged between slight to fair for the ASIS (Kg=.06 to .26; mean Kg=.19), and slight for the PSIS(Kg=-.04 to .18; mean Kg=.07) and slight to fair for the IC (Kg=.06 to .32; mean Kg=.21). Inter-examiner reliability was slight (ASIS Kg=.13; PSIS Kg=.05; IC Kg=.14). These results suggest that the reliability of the assessing SIJ anatomical landmarks using palpation and observation as an indication of SIJ dysfunction still remains questionable. Before this test can be relied upon as an accurate indicator of SIJ dysfunction, it must undergo further research. This further research needs to examine not only reliability, but also validity, sensitivity and specificity.

This study was performed to investigate the preference and perception on fruits especially, focusing on apples and pears served in elementary school lunch programs. The subjects of this study were 1,106 students (504 female and 595 male students)from seven elementary schools in Seoul. The survey was conducted by using self-administered questionnaire from July 10 to July 20, 2006. Based on the frequency analysis results, 45% of respondents ate fruits every day and 42% had fruits 2-3 times per week. Approximately, 53% of respondents indicated their usual time to eat fruits was after dinner and secondly 27% had fruits between lunch and dinner. Majority of respondents chose a watermelon as the most preferred fruits and the first chosen among nine fruits (apple, pear, madarin, strawberry, cherry tomato, watermelon, grape, melon, and peach). Cherry tomato was found as the least preferred fruits by 30% of students, however cherry tomato was most frequently offered fruits in elementary school lunch menu. About 50% students were satisfied with the served fruits in their school lunch program. In addition, most students said that they would have fruits more frequently in their lunch menu. However, one fifth of students addressed that they were not satisfied with the fruits in school lunch program because of kinds of fruits, freshness of fruits, taste of fruits, and quantity of fruits. Almost 71% of students preferred apples. Seventy three percents of students preferred eating apples without peel and 78% of students ate apples as slices of apples. In addition, 61% of students indicated their preference of apple salads. Many students responded they did not eat apples and pears frequently since they do not have a chance to eat them. The implications to increase the chance to eat fruits and promote elementary children's fruits consumption were discussed.

은 고분자 전해질은 올레핀/파리핀 혼합물 분리에 매우 효과적인 분리막 재료이다. 이는 고분자 매질속에 녹아 있는 은이온이 올레핀과 선택적, 가역적 반응을 통해 올레핀만을 분리막속으로 통과시키기 때문이다. 그러나 이러한 은 고분자 전해질 분리막은 실제 공정에 응용되기에는 다소 약한 장시간 운전 성능 안정성을 보인다. 즉 분리 성능이 시간이 지남에 따라 점차 감소되는데 이는 은이온이 은 나노입자로 환원되기 때문이다. 따라서 본 연구에서는 poly(vinyl pyrrolidone) (PVP)와 AgBF4로 이루어진 고분자 전해질막의 안정성을 향상시키고자 비이온 계면활성제인 C18H35(OCH2CH2)20OH (Brij98)를 첨가제로 사용하였다. 분리막속에서 은이온의 은 나노입자로의 환원현상을 원자전자 현미경과 자외선 분광학을 이용하여 분석하였다. 그 결과 Brij98이 첨가된 분리막의 경우 은 나노입자의 성장이 늦춰졌으며, 프로판/프로핀렌 선택도가 장시간 유지됨을 알 수 있었다.

Consumers keep demanding for diversified high quality products, valuable services and safety. With this in mind, Distribution Industry is being updated rapidly to accomodate this demand. Meanwhile, Distribution Information Technology of agricultural products has been in slow progress with little in-depth studies. In this study, it has been analyzed the usage of Bar code which is the key element for agricultural Distribution Information Technology. The analysis was conducted through a survey utilizing questionnaire covering 5 Hypermarkets(Super-centers) including big 3 companies. Also, Japanese market trends have been studied to visit a Japan Government Organization concerned, GS1 Japan, an Agricultural Cooperative, an Agricultural Wholesale Market, and a Retail Company. If we could use KAN code for all agricultural products, we could collect and analyze the information of price and trade quantity of them. It opens a new era to understand the agricultural products supply and demand easily. This will certainly make a great contribution to the evolution of agricultural products distribution. From this research, it is suggested that collective efforts by suppliers, wholesalers, retailers and Government Officers are needed to make large scale mutual marketing Organizations, which specialize in sending out agricultural products. The Organization is recommended to standardize and pack every final agricultural products, to promote the use of KAN code.
