"문자"는 저자와 문헌에 대한 불확실성 등으로 인한 문헌의 진위문제, 최근 출토된 죽간본과 통행본과의 관계 등 학계에서 논란되는 자료이다. 본 논문은, 잡가(雜家)와의 경계선을 모호하게 하는 황로학의 연구방식을 지양하기 위해 죽간본(竹簡本)과 통행본(通行本)이 공유하는 편장(篇章)을 중심으로, 도가학파의 도론(道論)과 대비시켜 "문자" 황로사상의 고유성에 대해 논의한다. "문자"는 도법가(道法家)의 유형으로 파악할 수 없는 유가유(儒家類)의 황로문헌으로, 노자학(老子學)에서 발원하여 유가(儒家)를 위주로 제가철학(諸家哲學)의 요체를 수용한 문헌이다. 본 논문은, "문자"는 이론적으로 노자학(老子學)에서 발원하지만 사회정치적 범주에서 유가(儒家)와의 주된 사상적 결합을 시도한 유가유(儒家類) 황로학이 형성되는 초기의 문헌임을 논증한다.

Since fire was founded in the world, human races have invented various heating methods. Ondol is traditional heating method in Korea. It is very the important work to trace the history and characteristics of Ondol which originated and was developed in the Korean peninsula. Especially, the study on Ondol will contribute to improving the present heating methods and predicting future ones. In this paper, we shall study through the analysis of documents such as oriental documents, the document of Choseon dynasty, European documents and American documents. In order to discover the origins of Ondol as one of the excellent heating method all over the world, This study aims at identifying the history and characteristics of Ondol in the Korean peninsula, through document analysis. Results of this study are as follows. 1) The first document about Ondol is Sookyongjoo(水經注), Chinese ancient geography book. Contents recorded in the book include the description related to Ondol at Kwankyesa temple which was located at the border land between Gogooryo(ancient Korea) and the northeast of China. 2) Ondol was popular heating method in Gogooryo(ancient Korea) and it was used in not only Gogooryo but also Silla Kingdom and Beakje Kingdom. Thereafter, it was also used widely in Goryo dynasty and Choseon dynasty. Thereby we know that Ondol has been used as a heating method for a long time in the Korean peninsula. 3) Ondol was covered with a floor paper since the beginning of Choseon dynasty. the paper made room clean and impacted on Korean life style. Because the floor was clean and warm, Koreans thus took off shoes and sat on the floor. 4) Ondol was spreaded to Jeju island in Korea before 16th century but wasn't used widely there. The reason was that Ondol was rare high class heating system and the weather was warm in Jeju island. 5) The overspreading of Ondol caused that poor people built roughly Ondol in the last of Choseon dynasty. So, the quality of Ondol gradually became lower and lower. 6) A westerner was impressed by the novelty of Ondol and Frank Lloyd Wright had played an important role to update and spread Ondol widely all over the world. Hailing Ondol as the ideal heating system, Frank Lloyd Wright began incorporating it in his buildings back in the U.S. and even invented a modified ondol system, using hot water running through pipes instead of the hot exhaust through flues.

This research aims to develop cultural products for professional sales after producing creative products utilizing dinosaur characters, which are the representative exhibited item of dinosaur-centered museum. There are seven museums in Korea whose theme is dinosaur. There are three dinosaur museums among them, Goseong Dinosaur Museum at Kyungnam, Mokpo Natural History Museum, and Seodaemun Museum of Natural History. While inspecting cultural products within the museum shops of these three museums, general products occupy more than 80% of all the products rather than products related to dinosaurs, and has a problem that most products are decorative ones. This resulted from that enterprises supplying these products are not professional ones and are irrelevent to cultural industry; as result, purpose of conveying culture through products is lost. This research develops dinosaur characters utilizing computer 3D techniques in order to imbue unique characteristics to dinosaur museums and informing cultural speciality of our country. In addition, this research presented design method of cultural products by grafting traditional symbols onto these characters, and actually produced 11 items of 5 kinds: toys(dolls), clothes(T-shirts, pajamas, socks), stationery(notebooks, memo), accessaries (bags, umbrellas, handkerchief), and others(cups). On the items above, dinosaur characters are variously utilized in form of printing, embroidery, and stickers by using computer 3D technique. A cultural product is a tangible form which could show variety of cultural characteristics of our nation that could spread the culture through the consumers, and such type of purchasing could increase values of cultural industry by creating economic profits; such points are the significance of this study.

Objective: The purpose of this study is to identify relationship between the PWV and the temperature difference. Methods: When it comes to senile patients who suffer from cold limbs, there is need to see whether or not the patient's low temperature of the limbs is do to arteriosclerosis. The Pulse Wave Velocity(PWV) is a non-invasive method measuring the artery's rigidness. And the Digital Infrared Thermal Imaging(D.I.T.I) is a non-invasive method to see the body's thermal change. Research on the interrelationship of the artery's rigidness and body's thermal distribution was done by using these two tests. The subjects of this research were patients between the age 40~65 who have done both the D.I.T.I and PWV in March 2005~ September 2005. They had to have no history of diabetes, coronary illnesses or cerebrovascular diseases which are diseases that can effect the outcome of the PVW, nor history of spondylopathy or dermatosis which can effect the outcome of the D.I.T.I. Results: The results were as follows. 1. There was a significant interrelationship between the right wrist-ankle PWV and the temperature difference of the right wrist-palm. 2. There was a significant interrelationship between the left wrist-ankle PWV and the temperature difference of the left wrist-palm. 3. There was no significant interrelationship between the right wrist-ankle PWV and the temperature difference of the right thigh-dorsum of foot. 4. There was no significant interrelationship between the left wrist-ankle PWV and the temperature difference of the left thigh-dorsum of foot. 5. The right ABI showed no significant interrelationship between the temperature difference of the right wrist-palm and the right thigh-dorsum of foot. 6. The left ABI showed no significant interrelationship between the temperature difference of the left wrist-palm and the left thigh-dorsum of foot. Conclusion: The study shows that there was a significant interrelationship between wrist-ankle PWV and the temperature difference of wrist-palm.

Objective: The aim of this study was to investigate 1) the difference in static lower extremity alignment (SLEA) according to a history of lateral ankle sprain (LAS), 2) to identify SLEA factors affecting LAS, and 3) to present the cut-off value and 4) the usefulness and limitations of the SLEA measurement. Method: This case-control study recruited 88 men (age: 27.78±4.69 yrs) and 39 women (age: 24.62±4.20 yrs) subjects with and without LAS. SLEA measurement protocol included Q angle, tibiofemoral angle, genu recurvatum, rear foot (RF) angle, tibal varum and torsion, navicular drop, ankle dorsiflexion range of motion (DF ROM). Independent t-test, logistic regression and receiver operating characteristic (ROC) curve were used for statistical analysis. Results: Men with a history of LAS had significantly smaller Q angles both in standing and in supine position, while women with a history of LAS had significantly greater DF ROM in non-weight bearing (NWB; p < 0.05). Logistic regression model suggests tibial varum (OR = 0.779, p = 0.021) and WB DF ROM (OR = 1.067, p = 0.045) were associated with LAS in men. In case of women, there were no significant SLEA factors for LAS, however, ROC curve analysis revealed standing RF angle (AUC = 0.647, p = 0.028) and NWB DF ROM (AUC = 0.648, p = 0.026) could be affecting factors for LAS. Conclusion: There are differences in SLEA according to the history of LAS, furthermore, the identified items were different by sex. In case of men, tibial varum and WB DF ROM affect LAS occurrence. Standing RF angle and NWB DF ROM of women could be a predictor for LAS. However, since the sensitivity and specificity in most of the SLEA measurements are low, kinematic in dynamic tasks should be considered together for a more accurate evaluation of LAS risk.

The purpose of this research is to seek for efficient health maintenance device and to suggest desirable daily habit, based on the inquiry on interrelationship between workers' daily lives and their heartbeat change level. The paper survey about general features, case history and daily habits was conducted on workers during medical examination in Jeollabukdo, and examined their change of heartbeat as well. The results of research deducted from data analysis are as follows; 1. There found very positive interrelations between time-domain analysis and frequency-domain analysis, and MHR and LF/HF ratio had negative connection with other analyses. 2. The recipient showed high time-domain analysis when they are younger, have worked shorter or have spouse, and it contributes to stable sympathetic nerve and parasympathetic nerve as it stimulates autonomic nervous system. 3. According to the result of frequency-domain analysis, recipients showed higher TP and LF when they are younger, and the highest HF when they are under 34.The level of VLF was higher for university graduates than the ones who finished high school. The recipients showed higher TP and HF when they don't have spouse, and lower TP, LF and HF when they have worked longer. 4. The level of RMSSD and TSRD was high for the people who don't have case history, and HF was high when they don't have any disease in progress. 5. According to the result concerning correlation of daily habits with time-domain analysis and frequency-domain analysis, cigarette, alcohol and sleeping hours don't affect heartbeat change, but the ones who regularly workout showed higher result in every analysis. It shows that the autonomic nervous system of recipients who regularly exercise response more actively. The result mentioned above suggests that the change of heartbeat is a direct index which shows the change of autonomic nervous system, and it depends on the exercise the most. Thus, workout is proved to be the best method in order for workers to take care of their health.

Some segment or segments of the body must compensate for the heel, and the higher the heel the greater the compensation. Such compensation was once generally thought to take place in the lumbar region and therefore to increase the lumbar lordosis. The purpose of this study is to analyze changes of lumbar sagittal curvature in barefoot and 6cm 12cm high-heel stance. We selected 19 subjects(11 males, 8 females} without history of lower back pain, significant spinal abnormality. And lateral view X-ray of lumbar region from T12 to S1 was taken of each individual. On each X-ray film, lumbar lordotic angle lumbosacral angle and lumbar segmental angles were measured by Cobb method. We drew the following interpretations from the analysis of measured variables of the lumbar region. 1. In comparison of barefoot 6cm heel 12cm heel stance, lumbar lordotic angle had a tendency to decrease according as the heel height was higher. The change in lumbar lordosis measured in high-heel stance was inconsistent with clinical forkelord of hyperlordosis in wearers of high-heeled. 2. Lumbar lordotic angle from T12 to L5 showed sex difference, and was more lordotic in female(p<0.05). 3. There was no sex difference in lumbosacral angle and lumbar segmental angles(p>0.05). 4. There was a significant correlation between lumbar lordotic angle and lumbosacral angle(r>0.60).

PURPOSE: Low-intensity exercise with restriction of blood flow has been proposed as an alternative exercise to secure the disadvantage of a high-intensity resistance exercise. However, studies of how affects the muscle using functional exercise are lacking. Thus, the purpose of this study was to investigate knee extensor muscle strength during stair exercise of functional exercise with leg blood flow restriction. METHODS: Twenty two healthy young adults with no history of musculoskeletal or neurogical disorder were participated in this study. participant were randomized into either non-restriction group(11 subject) or restriction group (11 subject). The restriction blood cuff attached to the proximal end of the leg. Measurement of knee extensor strength was used by cybex dynamometer. Data analyzed in independent t-test and paired t-test. RESULTS: Knee extensor muscle strength was significantly different between groups. Also, there were significant differences in the strength of knee extensor within the group. CONCLUSION: This study found that stair exercise with restriction of blood flow did influence to knee extensor muscle strength. These results will also be able to promote the effect of increasing the muscle power applied to functional exercise. Henceforth, studies will be made in the intervention method that can be applied to health vulnerable person.

The past bridge design specifications of Korea didn't include 1imitation on the amount of lap splices in the plastic hinge zone of piers, and so do current specifications. But these specifications include just limitation on the minimal length of lap splices. Thus, a large majority of non-seismically designed bridge piers may have lap splices in plastic hinge zone. In this study, model pier was selected among existent bridge piers whose failure mode is complex shear-flexure mode. Full scaled RC pier models whose aspect ratio is about 2.67 were constructed and quasi static test according to the drift level history was implemented. From the test results, effect of the lap splices on the seismic performance of bridges piers was analyzed, and the seismic capacity of the model bridges was evaluated by capacity spectrum method.
