Purpose: The objective of this study was to obtain improved susceptibility weighted images (SWI) of the cervical spinal cord using respiratory-induced artifact compensation. Materials and Methods: The artifact from $B_0$ fluctuations by respiration could be compensated using a double navigator echo approach. The two navigators were inserted in an SWI sequence before and after the image readouts. The $B_0$ fluctuation was measured by each navigator echoes, and the inverse of the fluctuation was applied to eliminate the artifact from fluctuation. The degree of compensation was quantified using a quality index (QI) term for compensated imaging using each navigator. Also, the effect of compensation was analyzed according to the position of the spinal cord using QI values. Results: Compensation using navigator echo gave the improved visualization of SWI in cervical spinal cord compared to non-compensated images. Before compensation, images were influenced by artificial noise from motion in both the superior (QI = 0.031) and inferior (QI = 0.043) regions. In most parts of the superior regions, the second navigator resulted in better quality (QI = 0.024, P < 0.01) compared to the first navigator, but in the inferior regions the first navigator showed better quality (QI = 0.033, P < 0.01) after correction. Conclusion: Motion compensation using a double navigator method can increase the improvement of the SWI in the cervical spinal cord. The proposed method makes SWI a useful tool for the diagnosis of spinal cord injury by reducing respiratory-induced artifact.

In Neijing("內經"), it explains heaven, earth, four seasons(天地四時) take part in human's birth, it gives influence on life support, and have organic relationship between body and movement of sun and earth(日月運行) of heaven and earth. Human body and the natural world corresponds, so the time changes in the natural world give immediate influence to human body, and correspond changes happen inside human body. This has no exception in qi of human(人氣), meridians, the viscera and organs(臟腑) and so on. In time, there are many kinds of cycles such as year, month, 10 days and a day. Yin and yang and the five elements in each cycle shows changes of prosperity and decay and transformation. In a year, there are spring, summer, late summer, fall and winter which are each included to wood, fire, earth, metal and water. Spring and summer belong to yang(陽), and fall and winter belong to yin(陰). A day can be divided into the crowing of the cook, dawn, noon, and twilight. After midnight yin falls and yang rises(陰盡陽生), and after noon yang falls and yin rises(陽盡陰生). Ups and downs of the qi and blood and human body change with time and the region of whereabout is different. In one month, when the moon is full qi of blood rises and when the moon comes down qi of blood falls. The qi of meridian(經氣) has a periodical changes with regular movement in meridian. This is a result of continuing movement of meridian and the nutrient(營) and the defense(衛) in human body, stars correspond with ups, and correspond with flow of water of meridian(經水) with downs. In a day the twelve meridians(十二經脈) in hour of yin(hours 3~5), it starts with qi and blood of lung meridian(手太陰肺經) prosperous, each qi and blood of meridian prosperous in order. In eight extra meridians(奇經八脈), Bideungpalbup(飛騰八法) per 5 days, Younggoopalbup(靈龜八法) per 60 days qi of pulse(脈氣) changes correspond. The qi and blood of five meridian points(五兪穴) is 5 days, so.

This study was planned to provide basic data for activating quality improvement by genera hospital with more than 400 beds across the country, of which 65 coordinators answered. Main results of the study are as follows.. 1. Job satisfaction and organizational commitment by individual characteristics were compared. It was revealed that the sense of self-efficacy was related to job satisfaction positively. But job satisfaction and organizational commitment by locus of control showed no significant difference. 2. In terms of the characteristics of QI activities, the active participation of QI coordinators in QI planning process and smooth communication among hospital staffs were showed positive relationship to job satisfaction significantly. 3. Also support system was proposed as most significant variable related to the job satisfaction and the organizational commitment of QI coordinators. Especially support to QI activities by CEO's, seniors, and other hospital staff was a factor to enhance the job satisfaction and organizational commitment of QI coordinators. 4. In the aspect of organizational culture, culture which were tendency to be recognized high autonomy in their work and organizational identity strongly and to operate reasonable compensation system were related to job satisfaction and organizational commitment positively. The more formalized climate, supportive communication, cooperative teamwork and promoting creative/risk take behavior, it showed the higher organizational commitment. 5. For the aspect of QI job characteristics, QI coordinators' job satisfaction was high when QI office was arranged for independent department which was exclusively in charge of QI activities and their role is exclusively in charge of QI. It can be concluded that organizational support in the aspect of relation and finance and efforts of encouraging their motivation and providing on the job training program are need.

It is well known that SuanXue QiMeng has given the greatest contribution to the development of Chosun mathematics and that the topics and their presentation including TianYuanShu in the book have been one of the most important backbones in the developement. The purpose of this paper is to reveal that Zhu ShiJie emphasized decidedly mathematical structures in his SuanXue QiMeng, which in turn had a great influence to Chosun mathematicians' structural approaches to mathematics. Investigating structural approaches in Chinese mathematics books before SuanXue QiMeng, we conclude that Zhu's attitude to mathematical structures is much more developed than his precedent ones and that his mathematical structures are very close to the present ones.

The study was performed to determine the reliability and validity of the 'Qi Blood Yin Yang Deficiency Questionnaire (Qi Blood Yin Yang DQ)' for the 100 subjects with chronic fatigue. After 100 subjects respond to the 'Qi Blood Yin Yang DQ', Korean medical doctor classified the subjects into 4 groups such as Qi deficiency group, Blood deficiency group, Yin deficiency group and Yang deficiency group. 100 subjects were retested in the same way after 3 weeks. The reliability and the validity of the questionnaire were inspected. Internal consistency of the 'Qi Blood Yin Yang DQ' was excellent (Cronbach alpha 0.916). Test-retest reliability was good (intra-class correlation coefficient 0.699). Construct validity analyzed by exploratory factor analysis produced 4 factors, which were selected from eigenvalues that are greater than 1.0. The 'Qi Blood Yin Yang DQ' consisted of 4 factors. The factor 1, 2, 3 and 4 showed 'Qi deficiency', 'Yin deficiency', 'Yang deficiency' and 'Blood deficiency' respectively. The 'Qi Blood Yin Yang DQ' restructured in this study may provide a fundamental questionnaire and a further study is required for a more advanced, standardized and statistically proven questionnaire.

The objective of this article is to induce that the conception of 'Qi-jul(氣質) and Qi-pum(氣稟)' was introduced to the Sasang(四象) Constitutional Medicine from bibliographic study on the theory of 'Qi-pum(氣稟)'. The conclusions summerized as followings. 1. In the oriental medicine, qualitative difference of 'zheng-qi(正氣)' among the individuals, the opposing power against a disease, is regarded as constitution. Having been used as 'nature(素)', 'quality(質)' and 'character(氣質)' in the oriental medical book, the word of 'Che-Jil(體質)' was used in good earnest at the end of 'Qing(情)' dynasty. 2. The nature(性) is divided into two, original nature(本然之性) and charicteristic nature(氣質之性) in the 'New confucianism(新儒學)' and the former means a principle(理), is a pure and good thing and used as a conception of universality, the latter is a principle of character and a imperfect imitation of principle(理). 3. It was repeatedly confirmed that 'Qi-jil and Qi-pum' meant the difference among the individuals by the dispute of 'Li-Qi(理氣)' caused by Lee Hwang(李滉) and Lee Yi(李耳) and by that of 'Ho-Rak(湖洛)' in the Ch'o-son(朝鮮) dynasty. 4. Han Sok-Ji, based on Meng-Zi(孟子)'s doctrine that man's inborn nature is good, criticized the theory of 'Qi-pum' which was 'Zhu-Zi(朱子)'s opinion and his opinion about the life(命) was thought to clue to the classification of the 'Sasang(四象)' invented by Lee Je-Ma as Park Se-Dang's theory that everyone has common nature but has different life(命). 5. By introducing the theory of 'Qi-pum' and the conception of life(命) which was understood as a special character by Han Sok-Ji and Park Se-Dang to Sa-sang constitutional medicine, Lee Je-Ma explained the reason why each man who was classified four constitutions, 'Taiyang'(太陽), 'Taiyin'(太陰), 'Shaoyang'(少陽), 'Shaoyin'(少陰), had the different formation of the visceral department(臟局).

Senile involution is divided into two classes : physiological senile involution and pathological senile involution. Physiological senile involution is a natural process of vital action of decreasing Vital Essence and Energy in kidney that is a necessary physiological phenomenon. Pathological senile involution is an evidence of impairment of True Qi of internal human body. Human vital action is a changing process of life, senility, sickness, and death. In other words, this is a natural process of being full and decreasing of Vital Essence and Energy in kidney, and True Qi of human body decides this process. The Vital Essence and Energy in kidney vary, and they are influenced and restricted by various elements. The time of a senile involution varies individually. Human body protects and makes efforts not to leak out True Qi in effective ways. We can postpone a limit of time of physiological senile involution phenomenon. This is called 'Health Preservation' - resistance against senile involution.
