The armillary sphere, an astronomical observation device embodying the Orbital Heaven Theory of the Later Han Dynasty in China, holds both historical and scientific significance. It has been produced in various forms by many individuals since its inception in the era of King Sejong in the Joseon Dynasty. A prominent figure in this field was Nam Byeong-cheol (南秉哲, 1817-1863), known for his work 'Uigijipseol' (儀器輯說), published in 1859, which detailed the history, production methods, and usage of the armillary sphere. This text particularly highlights 21 applications of the armillary sphere, divided into 33 measurements, covering aspects like installation, time, and positional measurements, supplemented with explanations of spherical trigonometry. Despite numerous records of the armillary sphere's design during the Joseon Dynasty, detailed usage information remains scarce. In this study, the 33 measurements described in 'Uigijipseol' (儀器輯說) were systematically classified into six for installation, nineteen for position measurement, seven for time measurement, and one for other purposes. Additionally, the measurement methods were analyzed and organized by dividing them into the ecliptic ring, moving equatorial ring, and fixed equatorial ring of the armillary sphere. In other words, from a modern astronomical perspective, the results of schematization for each step were presented by analyzing it from the viewpoint of longitude, right ascension, and solar time. Through the analysis of Nam's armillary sphere, this study not only aims to validate the restoration model of the armillary sphere but also suggests the potential for its use in basic astronomical education based on the understanding of the 19th-century Joseon armillary sphere.

Background: There are few studies that have reported on the pharmacokinetic(PK) disposition of fluoroquinolones in patients with multi-drug resistant tuberculosis(MDR-Tb), even though fluoroquinolones are frequently co-prescribed to those patients. In this study, the PK disposition of ofloxacin, a fluoroquinolone, was evaluated in patients with MD R -Tb. Methods: Twenty patients with MDR-Tb were given 2nd line Tb drugs including ofloxacin (300mg twice a day), prothionamide, cycloserine, para-aminosalicylic acid, kanamycin, and streptomycin. The patients were grouped according to their body mass index(BMI) as an index of emaciation (group A : 18.5$\leq$BMI <23, group B : BMI < 18.5). Blood samples were serially drawn and urine samples were collected upto 24 hours after the last dose of those drugs at steady state (over 1 month). The ofloxacin concentrations were determined using HPLC (High Performance Liquid Chromatography). Results: The AUC of ofloxacin in group B was greater than that in group A ($31.4{\pm}8.9{\mu}g/ml{\cdot}h$ vs. $24.1{\pm}6.2{\mu}g/ml{\cdot}h$)(Check the symbols), (p<0.05). The total clearance(Cl/F) of ofloxacin was $0.16{\pm}0.03$ L/h/kg in group A, and $0.14{\pm}0.03$ L/h/kg in group B. The half-lives of ofloxacin in two groups were similar (group A : $5.3{\pm}0.8$ hours, group B : $5.7{\pm}0.9$ hours). In addition, the other PK parameters in two groups were also similar. Conclusions: The pharmacokinetics of ofloxacin in patients with MDR-Tb appears to be comparable with those of normal subjects, and the extent of emaciation appears to have an influence on the pharmacokinetics of ofloxaicn in chronic debilitated MDR-Tb patients.

East Asian countries share a culture of perfuming clothes. The prosperity of the Maritime Silk Road and the incense trade are direct factors that have led to the development of incense culture. Perfuming clothes is a method of applying fragrance by burning incense. The Chinese could make an incense mixture with various types of incense, and records demonstrating use of perfuming clothes tools (熏籠) show that they might have perfumed clothes with incense mixtures. During the Tang dynasty, the incense trade thrived. Examples of ancient literature such as 『千金要方』, 『香譜』, 『香乘』 describe how to make incense for perfuming clothes and how to perfume clothes. 『桂海虞衡志』 and 『諸蕃志』 shows trade partners and goods. Incense was introduced to Korea alongside Buddhist culture. 『買新羅物解』 shows Silla traded incense with Japan. One of the trade goods recorded in 『買新羅物解』 is perfuming cloth incense (熏衣香), which establishes that Silla performed perfuming clothes at that time. During the Goryeo dynasty, Goryeo exported musk as well as ginseng. The royal family burned incense from the Song royal family. Noblewomen preferred sachets. The use of this dress continued into the Joseon dynasty. 『買新羅物解』 showed that Japan imported incense from Silla. 『The tale of Genji』 illustrates Heian nobles' incense culture, perfuming clothes culture, and trade of incense. Perfuming clothes tools became essential articles for marriage purposes and it developed in a practical shape. The Champa had a perfuming clothes culture. It is described on 『諸蕃志』. As Agilawood is found in Tongking, and Tongking was neighbor to the Champa and China, they might have had a perfuming clothes culture as well. Korea, China, Japan, and Vietnam shared a perfuming clothes culture. We can identify universality and commonality in the purpose of perfuming clothes, time of development, the method of making the incense mixture for perfuming clothes, the method of perfuming clothes, the tools, the gender of perfumer, and the type of herbs and spices.

This study analyzed how an aspect of translation can be shown on the 'Kureru type(くれる類)' verbs in "Kokoro", which was a Japanese modern novel when it was reproduced by translators. It focused on 'the use in accordance with a subject of expression and the other person' and 'the object of movement'. 'The use in accordance with a subject of expression and the other person' could be summarized as follows: The 'Kureru type' verbs were not translated only in accordance with the use of vocabulary in a dictionary. 'Kudasaru' was used in many examples of letter writing when 'the giver' was younger and it was translated to a polite form in Korean. 'Kureru' had a characteristic when 'the giver' was older in Korean translation. The act of parents was translated to an honorific form if parents were 'givers' regardless of whether a listener was an internal character or an external character in parent-child relationships. The degree of politeness was different in English translation when the 'Kureru type' verbs were used for asking a favor request command. 'Please' was used more for 'Kudasaru' than 'Kureru'. An aspect of translation in accordance with 'the object of movement' could be summarized as follows: The 'Kureru type' verbs were used as main verbs. 'Kureru' and 'Kudasaru' were translated to 'Juda' 'Jusida' in Korean translation, but they were translated to various vocabulary words in accordance with the characteristic of 'the object of movement' and were translated to imply a specific act, the process of possession and the result of possession in English translation. The 'Kureru type' verbs were also used as auxiliary verbs. The translated vocabulary words for Korean translation and English translation were different in accordance with whether the movement of things other than the movement of act was included or not. Examples were translated predominantly to expressions of profit such as '-Jada' '-Dalla' '-Jusida' when there was a movement of act as well as specific things in Korean translation. Also, some examples were translated to expressions of profit when there was the movement of act with an abstract matter and there was only the act of the object of movement, but many examples were translated to the act of first verbs. Examples were translated predominantly to the act of first verbs when there was the movement which included specific things and abstract matters or there was only the movement of act in English translation. Expressions of asking a favor request such as 'Kureru' and 'Kudasaru' were translated to '-Dalla' '-Juseyo' in Korean translation, but they were translated to expressions which specify an act while focusing on the structure of sentences or the function of language, such as 'must', 'ask', 'wish', 'would', and 'would like to' 'please' in English translation.

General procedures of seed preparation as conventional guide had been established in China before most of Korean literature documented them. ‘Chwijongbeob’ (method of seed select) was to select good quality of seeds and to discard the rest. In ‘Seonjongbeob’ (method of seed grading) although China employed only ‘Sooseonbeob’ (method of seed select with water), but seeds were selected in order of selection of seeds by winds, selection of seeds by sieve and selection of seed with water in Korea. As compared with the recent techniques, those methods were perfect techniques for selection of good quality seeds of rice, except for method of seed selection by salt water was developed. The method for measurement of seed moisture, and for measurement of melted snow, spoiled urine and extracted juice by boiling water with the bone of livestock were originated from ancient China. The farming books in Korea were more or less followed the above methods. However, these techniques were complicated and impractical interms of validity and rationality. Also, it is judged that these tchniques are more appropriate in dry areas and alkaline soil of China rather than in Korean conditions. The plowing is a work to begin farming, and is operated for air ventilation between atmosphere and earth. Also, this techniques was adopted in the farming books from the early to the late Chosun dynasty without changes. Fields were deep-plowed in the first, in fall (or in spring) and for cultivation, and were shallow -plowed in the second, in spring (or in summer) and in intertillage. The former was for water reserve and land preparation, and the later was for weed control with intertillage. However, plowing in fall which was different from fallowing in dry areas, was recommended in Korea (Jikseol). but was not practiced in Sejongsilrok. This was changed with time, and plowing for cultivation in Korea was interrelated with use of green manure crops, method of plowing of upseting plough, method of manure practice and sometimes dry plowing. In addition, until the 15th century method of using a kind of plowing-tool made of log as farm tools was created to support reclamation for enlargement of farm land in mountaineous and coastal areas. For desolate farm lands by many internal and external disturbances, one tried to recover yield ability by increasing labor productivity from the 17th or 18th century. To do this, ‘Banjongbeob’ (culture method by upset plowing weed control) and ‘Hwanubeob’(culture method by firing weed control) which were cultural methods of ancient China were readapoted but the results were not clearly informed. Also, the reality of those was reexamined in the end of the Chosun dynasty.

Introduction: The use of rabbits as a cardiopulmonary bypass(CPB) animal model is extremely dif%cult mainly due to technical problems. On the other hand, deep hypothermic circulatory arrest(CA) is used to facilitate surgical repair in a variety of cardiac diseases. Although steroids are generally known to be effective in the treatment of cerebral edema, the protective effects of steroids on the brain during CA are not conclusively established. Objectives of this study are twofold: the establishment of CPB technique in rabbits and the evaluation of preventive effect of steroid on the development of brain edema during CA. Material '||'&'||' Methods: Fifteen New Zealan white rabbits(average body weight 3.5kg) were divided into three experimental groups; control CA group(n=5), CA with Trendelenberg position group(n=5), and CA with Trendelenberg position + steroid(methylprednisolone 30 mglkg) administration group(n=5). After anesthetic induction and tracheostomy, a median sternotomy was performed. An aortic cannula(3.3mm) and a venous ncannula(14 Fr) were inserted, respectively in the ascending aorta and the right atrium. The CPB circuit consisted of a roller pump and a bubble oxygenator. Priming volume of the circuit was approximately 450m1 with 120" 150ml of blood. CPB was initiated at a flow rate of 80~85ml/kg/min, Ten min after the start of CPB, CA was established with duration of 40min at $20^{\circ}C$ of rectal temperature. After CA, CPB was restarted with 20min period of rewarming. Ten min after weaning, the animal was sacrif;cod. One-to-2g portions of the following tissues were rapidly d:ssected and water contents were examined and compared among gr ups: brain, cervical spinal cord, kidney, duodenum, lung, heart, liver, spleen, pancreas. stomach. Statistical significances were analyzed by Kruskal-Wallis nonparametric test. Results: CPB with CA was successfully performed in all cases. Flow rate of 60-100 mlfkgfmin was able to be maintained throughout CPB. During CPB, no significant metabolic acidosis was detected and aortic pressure ranged between 35-55 mmHg. After weaning from CPB, all hearts resumed normal beating spontaneously. There were no statistically significant differences in the water contents of tissues including brain among the three experimental groups. Conclusion: These results indicate (1) CPB can be reliably administered in rabbits if proper technique is used, (2) the effect of steroid on the protection of brain edema related to Trendelenburg position during CA is not established within the scope of this experiment.

The fertilizer experiment was conducted to establish a pattern of a continuous application of organic matter in rice-barley cropping system. Fine textured gray lowland soil was used to grow the crops. The amount of nitrogen absorption and the yield of the crops were the highest in barnyard manure 1,000kg/10a. A correlation among the content of humus and nitrogen, the amount of nitrogen absorption, and the yield was significant while it was not significant among the the nitrogen content of the soil fertility, the total nitrogen, and the yield of crops. The result of this research suggests that revelation of available nitrogen after the decomposition of the organic matter depending on climate and regions should be studied for the organic matter application in due season.

Modern design has to be satisfied to user in various social class. Therefore a study of lifestyle is vary important as a basic of design. The logical starting point to grasp the user's needs is begun by consumer analysis. There are many methods of consumer analysis, In them, the study of lifestyle is extremely much used for understanding consumer who is classified with groups. Basic education of design have to teach knowledge and ability which is to be a groundwork for designer. The study of lifestyle is not a purpose itself but one of theoretical knowledge which is requested for design. By induding practical techniques and theory, theory can be achieved through practical techniques and the meaning of theory itself could be recalled. The value of this study is in the suggestion which is the way of approach to research and to study for oneself, by introduce the study through conceptual approach for lifestyle into basic design educational program. For the study of lifestyle, let students have the theoretical knowledge which is concept of lifestyle, modern social form, consumer culture, the way of using lifestyle and theorizing lifestyle, etc, And after, let students make teams for the study of lifestyle for oneself. Every team creates the subject and studies lifestyle of each social dass by the practical way such as Inquiry, observation and interview etc. As a result they have to make a report after the form of paper and let them have a presentation in each team. Students can understand lifestyle through this process not only theoretical but also practical and can be earned an ability for apply to business.
