I. Introduction Bi(痺) means blocking. It can reach at the joints or muscles or whole body and make pains. Numbness and movement disorders. BiJeung can be devided into SilBi and HeoBi. In SilBi there are PungHanSeupBi, YeolBi and WanBi. In HeoBi, there are GiHyeolHeoBi, EumHeoBi and YangHeoBi. The common principle for the treatment of BiJeung is devision of the chronic stage and the acute stage. In the acute stage, BiJeung is usually cured easily but in the chronic stage, it is difficult. In the terminal stage, BiJeung can reach at the internal organs. BiJeung is one kind of symptoms making muscles, bones and jonts feel pain, numbness or edema. For example it can be gout or SLE etc. Many famous doctors studied medical science by their fathers or teachers. So the history of medical science is long. So I studied ${\ll}Bijeungjujip{\gg}$. II.

지속가능성이란 사회적, 경제적, 환경적인 영향을 전반적으로 고려하며, 인간의 건강과 생활 증진을 내포하고, 환경자원의 보호와 경제적 번영을 의미한다. 지속가능성에 대한 심도 있는 이해는 이러한 환경적인 영향에 대한 고려뿐만 아니라 원료 및 자원채취, 이송, 생산 협력의 전반적인 순환을 다루어야 한다. 화학산업의 지속가능한 발전은 화학공정안전의 발전을 통한 상호보완적인 강화없이 이루어지기 어렵다. 이러한 관점에서 화학공정안전은 국제시장에서 경쟁력 강화의 기회라고도 할 수 있다. 화학공정안전의 변화하는 새로운 패러다임은 현존하는 시스템과 생산공정의 기본 디자인을 고려한 총체적 순환 전 과정으로부터 나온다. 이렇게 화학공정안전을 향상시키기 위해서는 관리 시스템을 포함한 정량적 위험성 평가 방법과 다양한 공정안전 데이터 및 지식베이스를 포함한 통합 스마트시스템의 개발이 필요하다. 본 논문에서는 화학산업안전의 전 과정 순환의 필요성에 대해 언급하였고, 이를 향상시키기 위한 공정안전 신기술에 대해 논의하였다. 변화하는 공정시스템공학에서 사고 없는 지속 가능한 산업의 발전을 위해서는 3 가지의 S, 즉 안전(Safety), 안정(Stability), 안보(Security)의 조합이 적절히 이루어져야 할 것이다.

Micro-electro-mechanical systems (MEMS) gyroscopes are widely used in various robot applications. However, these conventional gyroscopes need to vibrate the proof mass using a built-in actuator at a fixed resonance frequency to sense the Coriolis force. When a robot is not moving, the meaningless vibration of the gyroscope wastes power. In addition, this continuous vibration makes the sensor vulnerable to external sound waves with a frequency close to the proof-mass resonance frequency. In this paper, a feasibility study of a new type of gyroscope inspired by insect halteres is presented. In dipterous insects, halteres are a biological gyroscope that measures the Coriolis force. Wing muscles and halteres are mechanically linked, and the halteres oscillate simultaneously with wing beats. The vibrating haltere experiences the Coriolis force if the insect is going through a rotational motion. Inspired by this haltere structure, a gyroscope using a thin mast integrated with a robot actuation mechanism is proposed. The mast vibrates only when the robot is moving without requiring a separate actuator. The Coriolis force of the mast can be measured with an accelerometer installed at the tip of the mast. However, the signal from the accelerometer has multiple frequency components and also can be highly corrupted with noise, such that raw data are not meaningful. This paper also presents a suitable signal processing technique using the amplitude modulation method. The feasibility of the proposed haltere-inspired gyroscope is also experimentally evaluated.

Objectives : There has not been the comparison research of medication on the Insomnia as the complementary significance of the Oriental-Western Cooperative Therapeutic Viewpoint so far. The aim of this preliminary research is to study Eastern and Western Medication Model for the Insomnia through the comparison of Oriental Medication based on "Sang Han Lon" and "Dong yui bo gam". Methods : The author researched oriental-western viewpoints and the present treatment condition of Sleep and Sleeping Pills with reference to Korean articles issued since 1975, dissertations, journals registered or candidated on KCI, alternative medicine journals on Pubmed, and books concerning Neuropsychiatry. In the field of Oriental medical study, this study was demonstrated on "The Oriental Medical textbook of neuropsychiatry", "Sang han lon", "Dong yui bo gam" and the present research trend. Results : In Oriental Medicine, Insomnia is treated according to si-jie-bu-shui-zung (思結不睡證) type, rong-xie-bu-zu-zung (榮血不足證) type, yin-her-nae-re-zung (陰虛內熱證) type, xin-dan-her-qie-zung (心膽虛怯證) type, dam-xian-yu-jie-zung (痰涎鬱結證) type, and wei-zhong-bu-he-zung (胃中不和證) type etc. In Western Medicine, Insomnia has been treated by Barbiturate over 60's and BZ over 70's. According to recent treatment on Insomnia, Zolpidem or Zaleplon, which is short-lived and has less side effects, is used much, and tri-cyclic antidepressants are prescribed on a chronic psycho-physiological insomnia. Conclusions : Generally, Insomnia is being treated by controlling whole ways. The oriental medication is less effective for sleep induction. On the contrary, that of western medication is very effective for sleep induction, but there are many possibilities of side effects. If this two mutual therapy is conducted cooperatively, more effective medical care might be expected. Therefore, it is considered that not only the oriental medical study for sleep induction, but the study of Oriental-Western Cooperative Therapy should be preceded to treat Insomnia from now on.

The main current of ancient Korean thought is based on Yuk(易) : which solves the principle of creation of universe letter(文字) which is the principle of geometry and three elements thought of circle square . It's related to the creation principle of the universe and regarded as a sign that demons-trates shows the way to read the mathematical principle. The original form of Korean clothes(Han-Bock, 韓服) is represents the structure of hu-man body which reflects a small universe. So a good structure and meaning of the human body is well read in the formation of Korean clothes(Han-Bock, 韓服) and that is a good symbolization of the clothes(Han-Bock, 韓服) as the space of small universe. The good formation of Korean clothes(Han-Bock, 韓服) could be shown by cutting out straight bending twisting and turning each straitly cutting piece is applied to its trans-tormation. Geametical formation with obvious sym-metric dividing of front-back left-right and top-bottom is well shown in Korean clothes by twisting Yuk(易) or m bius strips. So we can find out whole formation by representing only either 'front and back' or 'left and right' and also sa-pok(사폭) of man's trousers seop(섶) of jeo-go-ri(short jacket 저고리) kyut-ma-gi(곁마기) of Sam-hwai-jang jeo-go-ri (삼회장 저고리), mu(무) of jig-ryung(straight collar and long and wide sleeved robe, 直領) trouser wide and ga-rae-ba-dae(가래바대) of dan-cok-kok(woman's under trousers). The formation line of Korean clothes(Han-Bock, 韓服) is based on theprinciple of unlimited m bius strips by twisting of turning direction from universal principle and original basic form is not changd even by turning in-side out. Unity of the whole and part in Korean clothes(Han-Bock, 韓服) could be found in nonorientable thought(非始原思想) which represents the unity and dependence kil(길) of jeo-go-ri(short jacket, 저고리) and po(long and wide sleeved robe, 袍). Selva-gewise(식서방향) of sleeves and seam of out-side of kil(길) and outside of seop(섶) are directed to outside of seop(섶) inside of seop(섶) is to kil and direction of inseam of kheut-dong(끝동) and kyut-ma-gi(곁마기) is directed to sleeves. Korean clothes(Han-Bock, 韓服) is usually made by cutting fabric for several parts and sewing them and the way to make Korean clothes is deeply related to the theory of chon-pu-kyung jong-il and il-seok -sam-geuk. As the development of men's consciousness is pro-gressed from total separation to separation and superseparation. Sewing process of korean clothes(Han-Bock, 韓服) can be make single dimension to double or triple dimension of korean clothes(Han-Bock, 韓服) silhoutte bacause it can be include principle of topology as noneuclity.

The aim of the study was to see if there is any differences in urinary 1-hydroxypyrene glucuronide (1-OHPG) and 2-naphthol levels in children ($8{\sim}14$ years old) and their mothers ($30{\sim}46$ years old) living three cities in South Korea (Seoul, Incheon and Pohang) and three in China (Changchun, Datong and Kunming), where the levels of air pollution varies. The factors related with urinary biomarkers levels were also evaluated. The study subjects consisted of 118 Korean (60 children and 58 their mothers) and 120 Chinese (60 children and 60 their mothers). Urinary 1-OHPG was measured by synchronous fluorescence spectroscopy after immuno-affinity purification using monoclonal antibody 8E11 and urinary 2-naphthol concentrations were determined by HPLC with fluorescence detector. Information on recent consumption of diet containing high PAHs, environmental tobacco smoke (ETS), type of cooking and heating fuels, and other life-style characteristics were collected by self-administered questionnaire. The arithmetic mean of urinary 1-OHPG levels (n = 120, $mean{\pm}SD$, $6.77{\pm}7.96{\mu}mol/mol$ creatinine) in Chinese were 10 fold higher than those in Korean (n = 118, $0.62{\pm}0.61{\mu}mol/mol$ creatinine) (P < 0.01). Urinary 2-naphthol levels in Chinese (n = 119, $59.50{\pm}82.29{\mu}g/g$ creatinine) were significantly higher than those in Korean (n = 117, $25.09{\pm}46.56{\mu}g/g$ creatinine) (P < 0.01). Urinary 1-OHPG and 2-naphthol levels were significantly higher in children living the polluted cities in China (Datong and Chanchun, respectively). Multiple linear regression analysis indicated that living in factory area (vs. residential area) and use of coal stove as heating fuel were significant predictors for urinary 1-OHPG (overall model $R^2$= 0.46, n = 204). And ETS was predictor for urinary 2-naphthol levels in Korean ($R^2$ = 0.36, n = 46). These results indicated that urinary 1-OHPG and 2-naphthol levels were related with different ambient particulate air pollution, type of heating fuels and ETS.

The Song Dynasty(宋代) period gained the summit in the developmental phase of the history in pediatrics. In 1076, Taeuiguk(太醫局) was founded and Sobangmaek(小方脈) was the one of nine branch in Taeuiguk(太醫局). As a result, educational agency and system was arranged in the field of pediatrics. At the same time, pediatrics have furnished with foundation to develop independent field in medical science. Especially, Byeonjeungnonchi(辦證論治) system is established in pediatrics science according to the compilation of "Soayakjeungjikgyeol(小兒藥證直訣)" by Jeoneul(錢乙). Children's doctors, Jeoneul(錢乙), Jinmunjung(陳文中) and Donggeup(董汲) arranged clinically theories, so they made that age the peak of the pediatrics. Looking at the developmental part of theory in pediatrics of the Song Dynasty period, Jeoneul(錢乙), who was the representative children's doctor in Song Dynasty period, insisted that children had formed Ojang-yukbu(五臟六腑) in the physiological part but they were not perfect like adult's. Therefore they had to consider the poor part in children's body, and then they had to cure them. 'Byeonjeung(變蒸)' was considered to be normal physiological phenomenon. Also he insisted that Yukeum(六淫), 'Pung, Han, Seo, Seup, Jo, Hwa(風, 寒, 暑, 濕, 燥, 火)' and 'Gyeong, Pung, Gon, Cheon, Heo(驚, 風, 困, 喘, 虛)' are the main cause of the children's five vital organ's pathology Like this, his academic thought, which lay emphasized on children's spleen and stomach and Ojangbyeonjeung(五臟辦證) main principles, affected on doctors, Donggeup(董汲), Yeomhyochung(閣孝忠), Yubang(劉肪), Jang-wonso(張元素), Idong-won(李東垣), Manjeon(萬全). Bangje(方劑) fields of pediatrics had developed so fast and "Taepyeongsunghyebang(太平聖惠方)" contained about 2689 kinds of children's prescription. According to this, there are so many kinds of medicinal shape, for example 'Hwan, San, Go, Dan(丸, 散, 膏, 丹)', which cured children' s disease. Through this, we find that the shape of medicine about the children's diseases had developed to the more simple direction, taking account of the children's clinical trait.

Recently, it has been a big issue to distinguish the dried roots of Cynanchum wilfordii and C. auriculatum in health functional food market. The original plant species of Cynanchi Wilfordii Radix belong to the Asclepiadaceae family is differentially described in the national pharmacopoeia of Korea, China and Japan. Owing to the morphological similarities of the dried roots of this plant to those of C. auriculatum, which is often misidentified in Korean herbal medicine marketplace, distinguishing these two species is exceedingly difficult. The purpose of this study was to compare the conventional-PCR with the real-time PCR for detection of C. wilfordii and C. auriculatum DNA. We also tried to realize a quantitative real-time PCR assay using species-specific matK primers, which allowed us to estimate the ratio of C. willfordii and C. auriculatum using varying ratios of mixed genomic DNA template from the two species. The differentiation of intentional and unintentional mixture in this study would be applied to food safety management and can be helpful for protection of consumer's right and cultivators.
