분할 맵 기반 얼굴 합성 분야의 기존 연구들은 피부 영역을 하나의 라벨로 취급한다. 이는 피부 내 미세한 요소를 표현하지 못하며 고해상도 영상 합성 성능 부족이라는 결과를 초래한다. 본 논문에서는 이러한 문제점을 극복하고자 분할 맵에 주름, 모공, 홍조와 같은 피부 요소를 추가하여 이로부터 얼굴 영상을 합성하는 기법을 제안한다. 기존 분할 맵 기반 영상 합성 연구에 제안하는 기법을 적용하여 정량적 및 정성적 비교를 통해 성능이 개선됨을 보인다.

The purposes of this article are understanding the meaning of yin deficiency interpreted with a perspective of Traditional Korean Medicine and a modern perspective a study and assigning modern diseases to yin deficiency pattern types. Clinical papers were searched in China National Knowledge Infrastructure(CNKI) from 1995 to 2013. Results are as follows. First, yin deficiency written in the "Neijing" has been understood in many ways. It is translated such as deficiency of yin qi, inner qi, essence, cubit pulse, yin meridians qi, viscera yin and kidney. Second, yin deficiency pattern are related with disorders of the endocrine system, immunity, energy metabolism, blood circulation, cytokine, microelements, lipid metabolism and capability of getting rid of oxygen free radicals. Third, from pattern types, diverse diseases classified in types involving the heat from yin deficiency, which reflects pathologic conditions of deficiency heat which is distinct characteristics of yin deficiency pattern. Various diseases classified in types related with liver or kidney are reported, which reflects two viscera are more related with yin deficiency than other viscera. Fourth, levels of pattern types surveyed are more specific than Korean Standard Classification of Diseases(KCD) and specific enough to be applied clinically. This article surveyed the categories of modern diseases yin deficiency pattern types is assigned to but the detailed relation between them will be necessary to be studied in the future.

Cobalt is an essential microelements in many biological processes involving enzymatic activity. We found that $Zn^{2+}$ and $Mg^{2+}$, which are in the active site of native calf intestine alkaline phosphatase (CIP), can be replaced by $Co^{2+}$ directly in solution. The effect of $Co^{2+}$ concentration on the substitution reaction was examined at ratios of [$Co^{2+}$]/[CIP] from 0:1 to 8:1. The quantity of $Zn^{2+}$ in CIP decreased progressively as the ratio was increased, but the amount of $Mg^{2+}$ changed in irrregular fashion. A series of active site models of the reaction mechanism of CIP are proposed. Low pH was found to promote the replacement of $Mg^{2+}$ by $Co^{2+}$. To understand how the substitution affects the enzyme, we also solved the secondary structure of CIP after reaction with $Co^{2+}$ in different conditions.

Nutrition fortification of processed foods with microelements is a popular practice in many countries to improve nutritional status of target population. In this study the current food fortification in Korea was evaluated and the regulations and guidelines for food fortification in other countries were presented. Most commonly added nutrients were calcium, vit.C, fiber, vit.Bs and iron. The level of fortified nutrients and the vehicle foods were variable. vit.C and fiber appeared to be overfortified in some foods and the necessity of fortification of these nutrients needs to be examined since the intakes of these elements appears to meet the RDA. Most of other nutrients such as vit.A, vit. $B_1$, vit. $B_2$, and iron were added at the level of 10~25% RDA per serving size. The vehicle foods for fortification were snacks, milk, ramyun, breakfast cereal, juices, candies and ready-to-eat retort pouch foods but not rice which is a staple food in Korea. The guideline and regulation for food fortification is required to ensure safe and proper supplementation of needed nutrients in processed foods.

Mass and flow resistance in a square ribbed microchannel have been studied numerically using the Lattice Boltzmann Method. It has been build up on two dimensional nine velocity vectors model with single relaxation time method called the Lattice Bhatnagor-Gross-Krook model. To analyze the roughness effect on the flow resistance namely the friction factor and mass flow has been discussed at the slip flow regime, $0.01{\leq}Kn{\leq}0.10$, where Kn is the Knudsen number. The wall roughness is considered by square microelements with a relative roughness height up to maximum 10% of channel height. The velocity profiles in terms of streamlines near the riblets are demonstrated to be responsible for the roughness effect. It is found that the roughness effect leads to increase the flow resistance with roughness height but it is decreased significantly with increasing the space between two roughness elements as well as the Knudsen number. In addition, the mass flow decreased linearly with increasing both roughness height and gap but significantly changed at the slip flow regime.

Yang deficiency pattern is a representative syndrome differentiation. This article is a study on to which categories of modern diseases yang deficiency is assigned by reference to modern clinical papers and the meaning of yang deficiency interpreted with a perspective of Korean Medicine and a modern perspective. Yang deficiency, yang qi deficiency, lack of yang qi and yang qi debilitation are the words found in "Nei Ching" and yang qi can be interpreted as something to warm, drive and arouse. Zhangzhongjing considered recovery or loss of Yang as the key to life in "Shanghanlun". Danxi proposed "Yang being liable to hyperactivity, Yin being insufficient" and emphasized pathological ministerial fire of Yang exuberance rather than physiological ministerial fire of Yang deficiency. Zhangjingyue proposed "Yang not being in excess, Yin being often deficient" and understood growth and decline of yin qi are all led by yang qi and put emphasis on true yin in addition to yang qi. Diseases of yang deficiency pattern are related with decline of metabolic level, hypofunction of internal secretion, disorder of immune function, disorder of automatic nerve system, sympathetic nerve inhibition, metabolic disorder of microelements, increase of cGMP, change of microcirculation, low speed of blood stream, kidney malfunction. Diseases related with kidney are sterility, polycystic ovary syndrome, spinal stenosis, edema, renal failure, IgA nephropathy, erectile dysfunction, nephritis, prostatitis, benign prostatic hyperplasia, decrease of adrenal cortical hormone by nephrotic syndrome, myelodysplastic syndrome. Disease related with heart are heart failure, arrhythmia, cardiomyopathy, atherosclerosis heart disease, hypertension, hyperlipidemia, pulmonary heart disease. Diseases related with spleen are irritable bowel syndrome, ulcerative colitis. Diseases related with liver are hypothyroidism, liver cirrhosis ascites, hepatitis B, chronic hepatitis, hepatic diabetes. Diseases related with lung are allergic rhinitis, cough variant asthma, bronchial asthma, pulmonary emphysema. And diabetes mellitus, metabolic syndrome, aplastic anemia, headache, encephalatrophy, Alzheimer's disease are also related with yang deficiency.

The objective of this study was to evaluate the nutritive value of selected fruits (pods and seeds) and leaves of acacia tree species namely; Acacia nubica (nubica), Acacia tortilis (tortilis) and Acacia brevispica (brevispica), Acacia reficiens (reficiens) and Acacia senegal (senegal). A wide variability in chemical composition, polyphenolics and gas production was recorded. The crude protein (CP) ranged from 131 to 238 g/kg DM. Neutral detergent fiber (NDF), acid detergent fiber (ADF) and lignin (ADL) were higher in senegal and significantly different (p<0.05) from other species. The nitrogen bound to fiber tended to be higher in leaves than the fruits, ranging from 2.6 to 11.3 g/kg NDF and 1.6 to 3.2 g/kg ADF. The leaves of reficiens and senegal had higher concentrations of total extractable phenolics (TEPH), total extractable tannins (TET) and total condensed tannins (TCT), but lower in NDF, ADF and ADL than the fruits of nubica, tortilis and brevispica. Mineral concentrations varied among species; all were relatively poor in phosphorus, moderate in calcium and magnesium, and rich in microelements. A significant (p<0.05) variation in gas production after 12, 24, 48, 72 and 96 h was recorded between species. Nubica had the highest (p<0.05) rate of gas production (0.0925) while the highest potential gas production was recorded in tortilis. A strong negative correlation between TEPH and TET with gas production after 24, 48, 72 and 96 was established (r=-0.72 to -0.82). Crude protein and TCT correlated negatively but also weakly with gas production characteristics. Organic matter digestibility calculated from gas production after 48 h (OMD48) ranged between 465 g/kg DM in reficiens and 611 g/kg DM in tortilis. The results of this study indicate that acacia species have the potential to be used as feed supplements.

Phytophthora capsici에서 원형질체를 형성, 재생 시키는데 관여하는 요인에 대해 조사연구하였다. 삼투압조절제로서 0.35 M $CaCl_2$가 첨가된 Novozym 234를 6-9시간 처리하면 균사체에서 원형질체가 양호하게 나출되었다. 24시간 배양한 어린 균사체에서 가장 많이 원형질체를 나출시킬 수 있었으며, 또한 Novozym 234의 농도가 진할수록 효과적으로 원형질체가 나출되었다. 원형질체를 재생시키는데는 0.4 M mannitol과 0.1 M $CaCl_2$를 혼합한 것이 삼투압 조절제이었다. 원형질체의 재생률은 모든 영양소가 첨가된 Henninger 합성배지에서 가장 높았다. 아미노산이나 ${\beta}-sitosterol$은 원형질체의 재생에 영향을 미쳐 두 영양소가 빠지면 원형질체의 재생이 억제되었다. 특히 아미노산 중 L-aspartic acid와 L-glutamic acid는 원형질체의 재생을 촉진시켰다. 그러나, 미량원소는 원형질체의 재생에 영향을 주지 않았다.
