Objectives The purpose of this study is to know the present uses of pre-packed herbal medicine and their usefulness in Korean University Oriental Medicine Hospitals. Methods We selected 29 university hospitals to survey by using telephone and by mail. Results 1. The kind of packages that 29 hospitals uses were 2 layers, 3 layers and 3 layers with aluminum as the component layer, standing or non-standing pouch. 2. Total 24.1% hospitals are using 3 layers patch with aluminum because of their merits. The merits are preserving the quality of packaged drugs, blocking sun lights and beautiful looking, gas barrier properties and an opening convenience. 3. However, the 3 layers with aluminum packages were little bit more expensive and it can't be used in the microwaves. Conclusions This study revealed that 3 layers with aluminum packages were superior to any other packages because it can keep original flavor and properties, block sun light, and an easy opening convenience. Thus, aluminum contained 3 layer packages are better to preserve herbal medicines.

In order for stable demand-supply and regularity of distribution, "The regulations for management of demand-supply and distribution of medicinal herbs" were established on 1995. Therefore, the medicinal herbs of good quality have been controled to be distributed in the market. However, to be wide of the purpose, the standardized sound distribution system was caused due to the governmental control on demand-supply to protect domestic farmers who produce the material for medicinal herbs, which results in the over distribution of non-standardized or illegally imported medicinal herbs. In addition, because of the distribution of faulty or poor medicinal herbs, there are chances of affecting bad effects on public health. The standardized medicinal herbs cover 514 different kinds in total, of which 69 products are specified to be standardized in the oriental medicine product companies. Also, in order to protect farmers who produce the materials for medicinal herbs, the amount of imported materials are regulated in normal times. The 14 different materials for medicinal herbs, which are allowed to be imported to a certain amount only when the shortage of goods or sudden rise of prices is to happen, are frequently introduced into domestic market as food not as medical usage, and the origin of those illegally changes to home cropped one for the distribution in the market. In addition, the system of distribution are to be disordered and the condition for the distribution of medicinal herbs of good quality can not be made since they illegally changes the usage of the materials for medicinal herbs from their original one and can not be regulated by the domestic laws.

Seismic analysis for steel frame structure with brace configuration using topology optimization based on truss-like material model is studied. The initial design domain for topology optimization is determined according to original steel frame structure and filled with truss-like members. Hence the initial truss-like continuum is established. The densities and orientation of truss-like members at any point are taken as design variables in finite element analysis. The topology optimization problem of least-weight truss-like continuum with stress constraints is solved. The orientations and densities of members in truss-like continuum are optimized and updated by fully-stressed criterion in every iteration. The optimized truss-like continuum is founded after finite element analysis is finished. The optimal bracing system is established based on optimized truss-like continuum without numerical instability. Seismic performance for steel frame structures is derived using dynamic time-history analysis. A numerical example shows the advantage for frame structures with brace configuration using topology optimization in seismic performance.

Kuramata Shiro's design has been evaluated as an unseen type of beauty. He created totally different aesthetics from functional furniture by utilizing glass, acrylic, and expanded steel mesh which usually are inappropriate for making furniture. Kuramata told that his design always starts from zero status. By doing so, he could be free from the existing notion and form of furniture. This means that every function and every form must be based on his own understanding and experiment in order to produce newness. Owing to these efforts, we can regard his design as artworks. Kuramata tried to bring forth formative lines inside contour of furniture rather than to deform only the formal outlines of furniture. These lines are very delicate and sometimes ephemeral. But they establish formal potentiality of phenomenological being of beauty. Also those lines are built from humble industrial material but they open the truth of thing itself and introduce the beauty to field of aletheia. At the same time, transcending limitation of function and use, they leave pure form and temporariness. So, lines become a field of Heideggerian rift which produces embodiment of form. We can appreciate his design through these lines that are relatively thin but vivid enough to follow his original world of art.

Roughage feeds were produced from Hyun-aspen (Populus alba $\times$ P. glandulosa) by autohydrolysis. The objectives of this work were to find proper conditions for the treatment of Hyun-aspen by analyzing the compositional change and digestibility and to determine the content of sugar and phenol contained in liquor extracted by digestion. The results of this work were as follows: 1. The proper condition for autohydrolysis of Hyun-aspen chips were $160^{\circ}C$ and 30 minutes in an autoclave. The yield of potential feed from original material and digestibility were 91.3% and 38.9% respectively 2. According to cooking conditions the sugar concentration of extracted solution and the recovery rate of sugar were 0.1~2.5%, 0.3~14.6% respectively. The phenol concentration of extracted solution and the recovery rate of phenol were 0.1~0.3, 0.5~1.8% respectively.

We present reconstruction of a complicated scalp-dura defect using acellular human dermis and latissimus dorsi myocutaneous free flap. A 62-year-old female had previously undergone decompressive craniectomy for intracranial hemorrhage. The cranial bone flap was cryopreserved and restored to the original location subsequently, but necessitated removal for a methicillin-resistant Staphylococcal infection. However, the infectious nidus remained in a dermal substitute that was left over the cerebrum. Upon re-exploration, this material was removed, and frank pus was observed in the deep space just over the arachnoid layer. This was carefully irrigated, and the dural defect was closed with acellular dermal matrix in a watertight manner. The remaining scalp defect was covered using a free latissimus dorsi flap with anastomosis between the thoracodorsal and deep temporal arteries. The wound healed well without complications, and the scalp remained intact without any evidence of cerebrospinal fluid leak or continued infection.

Recently, color reproduction properties have attracted lots of attention with mass production of LCD especially corresponding to TV application and achievement of color reproduction properties such as CRT have been considered one of technical goals for high quality display. However, revision of the color reproduction properties only with CF(color filter) have fundamental limitations and resultant decrease in the transmittance of panel causes demand on high brightness of BL(Back Light). In this paper, we present such a method in which by optimization of original light spectrum from the BL source will improves the color reproduction properties corresponding to them of the CRT. When the intensity of RED and Green-Blue from ramp is revised densely, the characteristics different from CCFL(Cold Cathode Fluorescent Lamp) used before become added so that about 11 % of the color reproduction properties is improved compare to the existing LCD panel.

In this paper, we propose and discuss the design using a simple method that reduces the fixed pattern noise(FPN) generated on the amorphous Si($\alpha-Si$) bolometer. This method is applicable to an IR image sensor. This method can also minimize the size of the reference resistor in the readout integrated circuit(ROIC) which processes the signal of an IR image sensor. By connecting four bolometer cells in parallel and averaging the resistances of the bolometer cells, the fixed pattern noise generated in the bolometer cell due to process variations is remarkably reduced. Moreover an $\alpha-Si$ bolometer cell, which is made by a MEMS process, has a large resistance value to guarantee an accurate resistance value. This makes the reference resistor be large. In the proposed cell structure, because the bolometer cells connected in parallel have a quarter of the original bolometer's resistance, a reference resistor, which is made by poly-Si in a CMOS process chip, is implemented to be the size of a quarter. We designed a ROIC with the proposed cell structure and implemented the circuit using a 0.35 um CMOS process.

Background: The aim of this systematic review was to investigate whether stem cells could be effectively applied in targeted therapy of breast cancer. Material and Method: A systematic literature search was performed for original articles published from January 2007 until May 2012. Results: Nine studies met the inclusion criteria for phase I or II clinical trials, of which three used stem cells as vehicles, two trials used autologous hematopoetic stem cells and in four trials cancer stem cells were targeted. Mesenchymal stem cells (MSCs) were applied as cellular vehicles to transfer therapeutic agents. Cell therapy with MSC can successfully target resistant cancers. Cancer stem cells were selectively targeted via a proteasome-dependent suicide gene leading to tumor regression. $Wnt/{\beta}$-catenin signaling pathway has been also evidenced to be an attractive CSC-target. Conclusions: This systematic review focused on two different concepts of stem cells and breast cancer marking a turning point in the trials that applied stem cells as cellular vehicles for targeted delivery therapy as well as CSC-targeted therapies. Applying stem cells as targeted therapy could be an effective therapeutic approach for treatment of breast cancer in the clinic and in therapeutic marketing; however this needs to be confirmed with further clinical investigations.

Objectives: This article aims to clarify the understanding and publication status of both The Treasured Mirror of Eastern Medicine (Donguibogam) and some of its recent research progress made in North Korea, as well as their influences upon the academic of Koryo medicine in North Korea. Methods: Analysis was carried out based on various reference books, dictionaries and Korean translation of Donguibogam (1964 Ver.) published by North Korea, as well as the North Korean quarterly medical journal, Koryo Medicine. Results: The academic of Koryo medicine in North Korea regards Donguibogam, a Korean medical classic as it was written by native Korean physicians and it became an important ground material for basic research and clinical study. Various terminologies used in the original version of Donguibogam were defined as unscientific and superstitious by North Korean academics, which were then subsequently removed from the Korean translation of Donguibogam (1964 Ver.) published by North Korea. Therefore, this version cannot be seen as a complete edition of Donguibogam. Conclusions: The Donguibogam is known as one of the 'three major books of Koryo medicine' in North Korea. As a treasure of East-Asian traditional medical classic, Donguibogam is expected to become the medium for a closer research collaboration between the North and South Koreas including China in the future.
