Obejective : Based on ${\ll}$sixty-ninth Nan${\gg}$ (${\ll}$難經${\cdot}$六十九難${\gg}$) the interpromoting of the five element's balance method to discuss following 'when deficiency than should strengthen mother and when excessive than eliminate son' theories. Method : This strengthening and eliminating method is based on Jang-bu organ's balance method when 'east is excessive (liver excessive (肝實 )) and west is deficiency (lung deficiency (肺虛))' then 'eliminate the south and strengthen the north's method. Results : The seventy-fifth Nan (${\ll}$難經${\cdot}$七十五難${\gg}$) explains' son effects mother's excessive and mother effects son's deficiency' theory where it balance method of the inter-overacting five elements controlling Jang-bu organ's differentiations. The eighty-first Nan (${\ll}$難經${\cdot}$八十一難${\gg}$) explains strengthening-eliminating method of 'lung excessive and liver deficiency.' Since there are two different perspective of seventy-fifth and eighty-first Nan, we must compare and discuss to make right point of view. Conclusion : the treatment method in ${\ll}$Nan kyoung sixty ninth nan${\gg}$ could be understood as a view of five element constitutional theory (五行體質理論), the treatment method in ${\ll}$Nan kyoung seventyty-fifth nan${\gg}$ of eleminating fire and strengthning water in case of liver excess and lung defficiency and the treatment method in ${\ll}$Nan kyoung eighty-first nan${\gg}$ of strengthning liver and eleminating lung in case of lung excess and liver defficiency could be understood as a view of the yin-yan constitutional theory (陰陽體質理論).

Objectives : This paper aims to examine the meaning of Shengmaisan in relation to original qi based on the discussion of Zhangyuansu, Lidongyuan and other doctors. Methods : Discussion of Shengmaisan made by Zhang, Li and others were examined. Afterwards, the medicinal properties of renshen, maimendong, and wuweizi as written in the Bencaogangmu, Donguibogam, Benjingshuzheng and texts of Zhang and Li were studied in relation to original qi. Related concepts such as '肺中伏火'·'補肺中元氣不足'·'補天眞元氣'·'夏食寒' were analyzed as well. Results & Conclusions : 1. Various pathology related to deficiency in original qi could act as internal pathogen for Shengmaisan application with which external factors such as summerheat and dampness heat meet results in most damage in the Lung metal. Therefore the upper body Lung is emphasized as pathogen. 2. The pathology of Shengmaisan application is depletion of humor, which should be refined, due to summer or dampness heat in a state of original qi deficiency which damages the Lungs, disabling its function of managing clear and pure qi. 3. The disease pattern for Shengmaisan in relation to original qi, according to other doctors, includes symptoms related to the Lungs such as dryness in the mouth due to excessive perspiration, blankness, loss of consciousness, shortness of breath, coughing, fast breathing, along with general bodily symptoms such as heavy sensation of the body, lethargy, difficulty walking, limping. These general bodily symptoms are due to either qi deficiency of the Lung, or humor deficiency due to failure of qi convergence in the lower body, or symptoms caused by Jing deficiency in severe cases. Symptoms related to problems in the lower body could manifest as dysfunction in urination and defecation, weakness in the limbs caused by original qi deficiency. 4. The Lungs circulate the clear and pure qi, converging qi and creating humor to assist the Triple Burner's Qi-Humor metabolism, enabling smooth communication of original qi throughout the body. With the original qi well tonified, the shen mechanism which is rooted in original qi allows for autonomous and consistent qi circulation within the body. Therefore, both Zhang and Li emphasized the importance of original qi. The property of Shengmaisan is explained as 'supplement qi/create liquid, convergence of yin/stop perspiration'. Zhang and Li explained its property as managing the circulation of original qi, to tonify Lungs' original qi and origin of water-humor.

We know very well the importance of water. Recently, we perceive the truth that water influence the quality of products and we must pay for it. Besides, we recognize why the water treatment is indispensable for life as well as industries. The variation of environment changes the natural resources and threatens the human life. Now, we cannot get water freely from nature. We should find new processes which are effective and inexpensive. We believe that the membrane technology can suggest the new way of water treatment. I'd like to explain the situation of water resource and the membrane processes by UF/MF membranes. I'll also introduce several case studies in this lecture. Till now, about 10 MF/UF systems were established in Korea. Of course, the usage of MF/UF for water treatment is beginning stage in Korea. But the future prospect is very good. Korean government has been developed various kinds of membrane processes for the purpose of drinking water, water reuse, development of new water resources and water related technologies, etc. In near future, maybe we will meet serious water problems, water deficiency and contamination. Fortunetely, we can suggest the membrane process for solving those problems. Membrane technology will be the base of clean technology.

This Chapter mentioned Terror and Palpitation due to Fright(驚悸) and Hemorrhagic disease(血證). Terror and Palpitation due to FrightAcctually Terror(驚) is different from Palpitation(悸). Terror(驚) is one of the seven emotions. But in this case, It refer to the Palpitation and the uneasiness of mind due to one's hearing a strange sound of seeing a strange. Tremulous Pulse can be appear. So Terror(驚) is caused by Exopathic Factors(外因) and belongs to Excess syndrome(實證). Palpitaion(悸) is the sensation of plamus, palpitation and unrest not because of being frightened. It is usurally caused by the deficiency of Ki(氣) and blood(血). So Deep, Thready and weak pulse can be appear. So Palpitaion(悸) is caused by Endopathic Factors and belongs to Deficiency Syndrome. In this Chapter, Terror and Palpitation due to Fright(驚悸) treat with the Kyeji-ke-jakyak-ka-chokchil-moryu-yongkol-kuyuk-tang(桂枝去芍藥加蜀漆牡蠣龍骨救逆湯) and Banha-mahwang-hwan(半夏麻黃丸). There are two type in Hemorrhagic disease(血證). One is bleeding(出血) and another is blood stasis(瘀血). The contents which relate with the Hemorrhagic disease(血證) are Hematemisis(吐血), Rhinorrhagia, Hemafecia(下血). In hemorrhage pathological mechanisms, there are two mechanisms. One is that Fire and Heat(火熱) pressure blood. Another is that cold and deficiency(虛寒) disable Ki(氣) from keeping blood flowing within vessels. Blood stasis(瘀血) can be called Extravasated Blood(惡血), Coagulated Blood, Blood retention(蓄血,積血), Dead Blood(死血) and Emaciation due to Blood disorder(乾血). It refer to a morbid state of unsmooth circulation and blood stagnancy often resulting from Ki(氣) stagnation, Ki(氣) deficiency and accumulation of pathogenic coldness. The symptom of Blood stasis are 'Fullness sensation in the chest, Lip Flaccidity, Cyonotic Tongue and Dryness of Mouth'. And the man who have Blood stasis, want to rinse his mouth with the water, but he can't drink the water because there isn't interior Heat of Excess Type. The symptom of Cyonotic Tongue(舌靑) had influence on diagnosing Blood stasis(瘀血) in offspring.

This study was conducted to evaluate nutrient intake, indices of anemia, serum lipids, and their correlations in 40 Korean female college students aged 21 to 25 years. Fasting blood samples were collected in October. 1997 Nutrient intake was investigated by 24-hour recall method for three days. Anthropometric measurements, blood pressure, iron status and serum lipids of the subjects were determined. The mean values for age. height, weight, BMI and blood pressure of the subjects were 22.1 years, 160.6cm, 54.4kg and 109.1/66.9mmHg, respectively. According to the body composition analysis, total body water, % body fat, lean body mass and WHR were 26.7L. 29.5%, 36.5kg and 0.8, respectively. Average daily intake of energy was 1,858.4kcal. Protein, phosphorus, vitamin B$_1$, vitamin B$_2$, niacin and vitamin C intakes were higher than the Korean recommended dietary allowence(RDA), whereas calcium, iron, vitamin A intakes were tower than that. Hemoglobin(Hb), hematocrit(Hct), serum iron(SI) and total iron binding capacity(TIBC) were measured and transferrin saturation (TS%) was calculated from serum. The mean values for Hb, Hct, SI, TIBC and TS were 13.6$\mu\textrm{g}$/㎗, 41.6%,97.8$\mu\textrm{g}$/㎗, 319.6$\mu\textrm{g}$/㎗ and 31.9%, respectively. The Prevalence rates of iron deficiency assessed by Hb and Hct were found to be 10% and 2.5%, respectively. However, when assessed with TIBC, the prevalence rate of iron deficiency was increased to 32.5%. The mean values for serum triglyceride(TG), total cholesterol(TC), HDL-Chol, LDL-Chol concentrations and atherogenic index(AI) were 154.7mg/㎗, 80.0mg/㎗, 47.4mg/㎗, 91.3mg/㎗ and 2.6, respectively. Correlations among indices of anemia. there were positive correlations between Hb and Hct, between SI and TS : negative correlations between TIBC and TS or SI. Correlations among serum lipids, there were positive correlations between TC and TG or LDL-cholesterol. Energy intakes were correlated positively with TIBC(p＜0.05), and vitamin C intakes negatively correlated with Hb(P＜0.05). And vitamin A intakes were negatively correlated with TG(p＜0.01). TC(p＜0.05) and LDL-Chol(p＜0.01). Hb negatively correlated with TG(P＜0.05). Body weights(p＜0.05), lean body mass(p＜0.05) and total body water(p＜0.01) werenegatively correlated with Hb. BMI and WHR correlated with TG and TC(p＜0.01). These results indicated that subjects with higher energy intake and overweight had a tendency to have iron deficiency. Increases in BMI and WHR were related to increases in serum lipids levels and decreases in TIBC. The results also showed that serum lipids were decreased when vitamin A and iron intakes were sufficient.

Denitrification is an important biological mechanism in wastewater treatment process because this process is technically to remove nitrogen from water to air. There have been lots of study about denitrification engineering and molecular biological research about denitrifying bacteria, respectively. However, combination of these researches was unusual and rare. This study is about the correlation between quantity of denitrifying bacteria and denitrification potential, and consists of NUR batch test as analysis method of denitrification potential and quantitative molecular analysis for denitrifying bacteria. Three reactors (A/O, MLE and A/O of nitrogen deficiency) are operated to get activated sludge with various denitrification potential. All samples which were acquired from reactors were measured denitrification potential by NUR test and NUiR test. Also, Real-time PCR was conducted for quantification of denitrifying bacteria composition in activated sludge. The various denitrification potentials were measured in the reactors. The denitrifiaction potential was the highest in MLE process and the reactor of the nitrogen deficiency showed the lowest. Genomic DNA of activated sludge was obtained and consequently, real-time PCRuse the primer sets of nirK and nirS　were conducted to quantify genes involving denitrification reductase production. As the result of real-time PCR, nirK gene showed more significant influence on denitrification potential comapred with nirS gene.

The deficiency of clean water is a major global concern because all the living creatures rely on the drinkable water for survival. On top of this, abundant of clean water supply is also necessary for household, metropolitan inhabitants, industry, and agriculture. Among many purification processes, advances in low-energy membrane separation technology appear to be the most effective solution for water crisis because membranes have been widely recognized as one of the most direct and feasible approaches for clean water production. The aim of this article is to give an overview of (1) two new emerging membrane technologies for water reuse and desalination by forward osmosis (FO) and membrane distillation (MD), and (2) the molecular engineering and development of highly permeable hollow fiber membranes, with polyvinylidene fluoride (PVDF) and polybenzimidazole (PBI) as the main focuses for the aforementioned applications in National University of Singapore (NUS). This article presents the main results of membrane module design, separation performance, membrane characteristics, chemical modification and spinning conditions to produce novel hollow fiber membranes for FO and MD applications. As two potential solutions, MD and FO may be synergistically combined to form a hybrid system as a sustainable alternative technology for fresh water production.

As a unutilized energy, treated sewage water locates widespread near urban areas. From the previous survey, the sewage water is reported to hold energy potential up to 36,000 Tcal/year, which was 2.1% of the total domestic energy consumption and 9.7% of the energy usage in the household and business sector in 2006. Temperature of the sewage water differs locally, but its range is observed in a range of $20{\sim}25^{\circ}C$ in summer and $8{\sim}13^{\circ}C$ in winter. Since the temperature range of the sewage water has a better seasonal distribution about $5{\sim}10^{\circ}C$ compared to ambient air, it is a promising heat sink for summer or heat source for winter. The sewage water is also a high quality heat source from its abundant quantity and uniform temperature. Considering the ambient temperature of Korea is very low in winter, a heat pump system using the sewage water can be an alternative to prevent problems of capacity deficiency and frost formation.
