According to the literatual study on the Infantile Vomiting since the publication of ${\ll}Hwangjenaekung{\gg}$, the results were as follows. 1. The causes of vomiting are classified into the following kind: external cause are the cold and heat, not external and internal are disorder of food and mood, internal are the dysfuntion of spleen, stomach, liver, kidney. 2. The Oriental Medical cause of Infantile Vomiting is disorder of food, intusion of outside evil, heat accumulation in the stomach, deficiency of stomach liquid, reverse flowing of Qi resulted from fear and being frightened. There are so many causes of Infantile Vomiting, but they are all related to the stomach. 3. The Western Medical cause of Infantile Vomiting are classified with the situation of stimulation, age, accompanied symptom. The main cause related with the age is inhalation of amniotic fluid, maternal blood, infectious disease, wrong lactation method, functional and organic abnormality. 4. The Infantile Vomiting is similar with the adults, but the spleen and stomach of infants is so feeble that the vomiting happens very easily. The reverse flowing of Qi resulted from fear and being frightened and disorder of food are the main cause in infants. 5. The cause of Infantile Vomiting between Oriental Medicine and Western's is so similar and both emphasized the function of spleen and stomach. But the comment on the external cause(cold, heat) and not internal & external cause(mood disorder) is a creative view of Oriental Medicine.

Objectives : Ojeok-san (OJS), an oriental herbal formula, has been used in Asian countries including Korea, China and Japan to treat the common cold and illnesses including fatigue and gastrointestinal disorders. The purpose of this study was to examine the anti-obesity effect and molecular mechanism of OJS, on adipogenesis in 3T3-L1 cells. Also, the effects of OJS in obese mice fed a high-fat diet on adiposity were examined.Methods : Preferentially, we analyzed the component of OJS and measured the stability of its component in OJS according to study periods using high performance liquid chromatography (HPLC). In vitro, 3T3-L1 cells were treated with OJS (50 to 200 μg/mL) during differentiation for 8 days. The accumulation of lipid droplets was determined by Oil Red O staining. The expressions of genes related to adipogenesis were measured by RT-PCR and Western blot analyses. For anti-obesty effect in vivo, we experimented for 8 weeks with four group (normal diet (CON), high-fat diet (HF), high-fat diet with OJS (HF+OJS) and high-fat diet with Bang-pung-tong-sung-san (HF+BTS) in comparison group HF+OJS).Results : OJS showed inhibitory activity on adipocyte differentiation at 3T3-L1 preadipocytes without affect cell toxicity as assessed by measuring fat accumulation and adipogenesis. In addition, OJS significantly reduced the expression levels of several adipocyte marker genes including proliferator activated receptor-γ(PPAR-γ) and CCAAT/enhancer-binding protein-α(C/EBP-α). Also OJS-administered mice showed significant inhibitory of body weights and abdominal adipose tissue weights.Conclusions : This study showed that traditional medicine OJS has an anti-obesity effect in vitro and in vivo. Thus, OJS could be developed as a supplement for reduction of body weight gain induced by an obesity.

Global fates of polychlorinated biphenyl(PCB) were investigated with a fugacity based multimedia transport and fate model, Globe-POP(persistent organic pollutant). The accumulation of PCB was directly affected by the emission patterns of PCB into the atmosphere and surface areas of environmental compartments. Partition coefficients and reaction rates also influenced on the accumulation patterns of PCB. The emission patterns of PCB in 10 climate zones were consistent for the past 70 years, while the contribution of PCB in high-latitude zones to the globe has increased by cold condensation. Considering the amounts of emission and accumulation of PCB, the North temperature zone is regarded as an important source and sink of PCB. Meanwhile, in spite of no significant sources, POPs accumulate in Antarctic environments mainly due to extremely low temperature. Finally we suggested that a global water balance accounting for snow/ice should be incorporated into multimedia environmental models for high-latitude zones and polar regions with the seasonal snow pack and/or permanent ice caps. The modified model will be useful to evaluate the influence of climate change on the fate of POPs.

Fluctuating climate is still most important environmental constrain, although improved modem agricultural technology has succeeded to increase crop production in the world. To stabilize the food production under fluctuating weather conditions, it is very needed to obain the quantitative information of interactions between crops and climate. The main purpose of this paper is three hold. Using the JIBP-data, the dry matter accumulation of rice crops is studied in relation to weather indexes (\SigmaTa and \SigmaSt). Temperature dependence of the yield index of rice is analyzed as to air temperature and water temperature. \SigmaT$_{10}$ -fluctuations are studied using meteorological data at various stations. The possible shift of \SigmaT$_{10}$ -isopleths due to climate fluctuation is evaluated. The second interest is in the plant climate of rice crops. Using results of canopy photosynthesis, it is pointed that the canopy structure has most important implication in plant climate. Leaf-air, stomatal, and mesophyll resistances of rice crops are described in relation to weather conditions. The change in light condition and aerodynamical property of rice crops with the growth is illustrated. The energy partition is also studied at different growing stages. Third point is to show in more detail effective countermeasures against cold irrigation water and cool summer. Heat balance of warming pond and polyethylene tube as a heat exchanger is studied to make nomo-grams for evaluating the necessary area and necessary length. Effects of windbreak net on rice crops are illustrated by using experimental and simulation results.lts.

It is generally analyzed that the subject area of grassland development seen in the North Korea area following unification with the South Korea includes hillland, h o w upland, tideland, and other expected grassland development areas. Possibilities and prospects for grassland development become higher if such grassland is developed by methods of environmental affinity suitable to the geographical and environmental conditions of North korea. First, the grassland development has to be based on grass species which are both cold resistant and suitable to the climate and the soil conditions of North korea. In addition, research on adaptable species, mixture combination selections and grassland establishment methods should be performed along with the accumulation of domestic data. The kind of research can be conducted in such areas as Yenben in China(Yenben University), Taekwanryung and Taeback mountains, where geographical features are similar to those of North korea. This research is possible because research can easily be given access to these locations. Hence, it is desirable to prepare for the unification of the Korean peninsula by caning out basic and applied research, and by way of accumulating data in the relevant fields.

In this work, a possible mechanism for grain evolution in Al-Mg alloy films during thermal annealing is suggested on the basis of the phase transition and the related residual stress. Al-Mg alloy films with compositions of 14.0 and 18.0 wt% Mg content were deposited on cold-rolled steel substrates by the direct current co-sputtering method using Al and Mg targets. After the deposition, the samples were thermally annealed at $400^{\circ}C$ for 10 min. The featureless, dense cross-sectional microstructure of the as-deposited films turned into a grainy microstructure after the thermal annealing. According to the residual stress evaluated by using the $XRD-sin2{\psi}$ technique and the phase analysis by XRD, it is likely that grains were created in order to relieve the additional accumulation of residual stress originating from the phase transition from face-centered cubic Al (${\alpha}$) to Al3Mg2 (${\beta}$) and Mg (${\delta}$) phases, suggesting interplay between the microstructure and residual stress.

Acute Mastitis(急性乳腺炎=乳癰) is an acute suppurative disease appearing in the breast. It is mostly caused by galactostasis, the stagnation of liver-qi(肝鬱) and stomach-heat(胃熱). It is mostly found in breast feeding women, mostly in primiparae. It usually appears in the third and the fourth weeks of postpartum. At the beginning in the chest there appear induration, distending pain, galactostasis, inversion to cold with fever followed by the enlargement of the masses, burning red, megalgia, not subduing of chills and fever, the accumulation of it to form pus. In the early phase it is advisable to follow the therapeutic principles of soothing the liver and clearing away heat, promoting lactation and subduing swelling. After the formation of pus it is advisable to cut radially and drain the pus. External Therapy(外治法) generally refers to all the methods to treat various diseases and symptoms with application of drugs and manipulation or together with proper instruments on the body surface except the method of taking medicine orally Acute Mastitis has been regarded as surgery or the method of taking medicine orally But, based on many bibliographies, acute mastitis was treated by external therapy. Thus through the historical bibliographic studies of external therapy about acute mastitis, this study was made to help the expanding of the methods of treating acute mastitis.

This study was wrriten in order to to help understanding of Kyeolhyung(結洶). Kyeolhyung is a syndrome of epigastric pain and fullness due to accumulation of pathogen in the chest mostly caused by too early purgation of Taiyang(太陽) channel syndrome which leads to the exterior syndrome of heat from the exterior into the interior or combines with the original excessive fluid of the chest. The knotted chest can be divided into large, small, heat and substantice, cold and substantice, water and blood Kyeolhyung. Kyeolhyung is basically treated by purgation but practically it is treated by according to its own symptom and syndromes. And we were cured of the Kyeolhyung discriminating from Zanggyul(藏結) and Bijeung(비증).

Buildings in the city acts as a cause of distorted wind direction, wind speed, causing the stagnation of the air flow. In the recent trend of climate change can not but consider the temperature rise of the urbanization. This study was aimed to analyze the thermal comfort of planetary boundary layer in different artificial constructions areas which has a direct impact on urban climate, and estimating the warming phenomena. Envi-met model was used to consider the urban structure associated with urban growth in order to precisely determine the impact of the building on the city weather condition. The analyzed values of thermal comfort index were temperature, wind speed, horizontal and vertical turbulent diffusivity. In particular, analysis of the PPD(Predicted Percentage of Dissatisfied) represents the human thermal comfort. In this study, by adjusting the arrangement and proportion of the top floor building in the urban it was found that the inflow of the fresh air and cooling can be derived low PPD. Vertical heat flux amount of the city caused by climate change was a factor to form a high potential temperature in the city and the accumulation of cold air does not appear near the surface. Based on this, to make the city effectively respond to climate change may require a long-term restructuring of urban spatial structure and density management.

As a possible feedstock for biodiesel, the marine green alga Tetraselmis sp. was cultivated under different conditions of phototrophic, mixotrophic and heterotrophic cultures. Glycerol, a byproduct from biodiesel production process, was used as the carbon source of mixotrophic and heterotrophic culture. The effects of glycerol supply and nitrate-repletion were compared for different trophic conditions. Mixotrophic cultivation exhibited higher biomass productivity than that of phototrophic and heterotrophic cultivation. Maximum lipid productivity of 55.5 mg L^-1 d^-1 was obtained in the mixotrophic culture with 5 g L^-1 of glycerol and 8.8 mM of nitrate due to the enhancement of both biomass and lipid accumulation. The major fatty acid methyl esters (FAME) in the produced biodiesel were palmitic acid (C16:0), oleic acid (C18:1), linoleic acid (C18:2), and linolenic acid (C18:3). The degree of unsaturation was affected by different culture conditions. The biodiesel properties predicted by correlation equations based on the FAME profiles mostly complied with the specifications from the US, Europe and Korea, with the exception of the cold-filter plugging point (CFPP) criterion of Korea.
