Traditional medicine has been integrated into the national health system in many countries such as Korea, China, Taiwan, etc. Korea and China are most representative among them. The purpose of this study is to compare the policies on traditional medicine in Korea and China focusing on where it came from and where it is headed. In this regard, the study suggested the first analysis tool in the world for analyzing the policy of traditional medicine. The results of the study are as follows: First of all, the development process of Korean Medicine (KM) and Traditional Chinese Medicine (TCM) shows the same pattern, that is, both are influenced by its own national policies. Secondly, the difference between the two countries is due to the gap in the development status or the different aspects in national heath system. TCM is more vitalized in health system and has larger category, and stays ahead in globalization compared to KM. TCM covers Chinese medicine, integrative medicine and ethno-medicine. Korea emphasizes the role of KM in the declining birthrate and aging society, and promotes the overseas patient invitation strategy. China, on the other hand, establishes the medical system for emergency medical treatment and preventive treatment of major diseases and promotes overseas expansion of TCM service. In addition, Korea stressed the safety and distribution of herbal medicine, and China emphasizes production technologies. Korea has a strong medical device industry along with the government's fostering policy; however, in China, medical devices are in the R&D stage yet. Even though both countries promotes the drug development from natural products, Korea focuses on developing herbal cosmetics in application industry, but China shows weakness in policies on application industry. China shores up the foundation for culture and theory of traditional medicine, while Korea doesn't have related policy. Korea places emphasis on promoting collaboration with international organizations and medical volunteer programs, whereas China is more interested in mutual cooperation and real trade with other countries.

We have investigated the influence of system composition and preparation conditions on the particle size of vitamin E acetate (VE)-loaded nanoemulsions prepared by PIC(phase inversion composition) emulsification. This method relies on the formation of very fine oil droplets when water is added to oil/surfactant mixture. The oil-to-emulsion ratio content was kept constant (5 wt.%) while the surfactant-to-oil ratio (%SOR) was varied from 50 to 200 %. Oil phase composition (vitamin E to medium chain ester ratio, %VOR) had an effect on particle size, with the smallest droplets being formed below 60 % of VOR. Food-grade non-ionic surfactants (Tween 80 and Span 80) were used as an emulsifier. The effect of f on the droplet size distribution has been studied. In our system, the droplet volume fraction, given by the oil volume fraction plus the surfactant volume fraction, was varied from 0.1 to 0.3. The droplet diameter remains less than 350 nm when O/S is fixed at 1:1. The droplet size increases gradually as the increasing the volume fraction. Particle size could also be reduced by increasing the temperature when water was added to oil/surfactant mixture. By optimizing system composition and homogenization conditions we were able to form VE-loaded nanoemulsions with small mean droplet diameters (d < 50 nm). The PIC emulsification method therefore has great potential for forming nanoemulsion-based delivery systems for food, personal care, and pharmaceutical applications.

The detection of skin pigment is crucial in the diagnosis of skin diseases and in the evaluation of medical cosmetics and hairdressing. Accuracy in the detection is a basis for the prompt cure of skin diseases. This study presents a method to recognize and measure human skin pigment using Hemoglobin-Melanin (HM) coordinate. The proposed method extracts the skin area through a Gaussian skin-color model estimated from statistical analysis and decomposes the skin area into two pigments of hemoglobin and melanin using an Independent Component Analysis (ICA) algorithm. Then, we divide the two-dimensional (2D) HM coordinate into rectangular bins and compute the location histograms of hemoglobin and melanin for all the bins. We label the skin pigment of hemoglobin, melanin, and normal skin on all bins according to the Bayesian classifier. These bin-based HM projective histograms can quantify the skin pigment and compute the standard deviation on the total quantification of skin pigments surrounding normal skin. We tested our scheme using images taken under different illumination conditions. Several cosmetic coverings were used to test the performance of the proposed method. The experimental results show that the proposed method can detect skin pigments with more accuracy and evaluate cosmetic covering effects more effectively than conventional methods.

The hydrolysis of biomass to fermentable sugar (saccharification) and to oligosaccharide is an essential process in biotechnology including biorefinery and biofood. Various macroalgae are commercially cultivated in several Asian countries as a useful resource for food and agar production. Agar is a major component of the cell walls of red algae that can be hydrolyzed by agarase. Agarases are classified into ${\alpha}$-agarase (E.C. 3.2.1.158) and ${\beta}$-agarase (E.C. 3.2.1.81) according to the cleavage pattern and grouped in the glycoside hydrolase (GH) family (GH-16, GH-58, GH-86, GH-96, and GH-118) based on the amino acid sequences of the proteins. Agarases have been isolated from various bacteria found in seawater and marine sediments. To increase productivity of the enzyme, a research on recombinant enzymes has been done. The application of recombinant agarase can be possible in the various filed such as energy, food, cosmetics, medical and so on. This paper reviews the source, biochemical characteristics and production system of recombinant agarases for further study.

One of the most significant medical advancements in human history is the development of vaccines. Progress in vaccine development has always been greatly influenced by scientific human innovation. The main objective of vaccine development would be to acquire sufficient evidence of vaccine effectiveness, immunogenicity, safety, and/or quality to support requests for marketing approval. Vaccines are biological products that enhance the body's defenses against infectious diseases. From the first smallpox vaccine to the latest notable coronavirus disease 2019 nasal vaccine, India has come a long way. The development of numerous vaccines, driven by scientific innovation and advancement, combined with researcher's knowledge, has helped to reduce the global burden of disease and mortality rates. The Drugs and Cosmetics Rules of 1945 and the New Drugs and Clinical Trials Rules of 2019 specify the requirements and guidelines for CMC (chemistry, manufacturing, and controls) for all manufactured and imported vaccines, including those against coronavirus infections. This article provides an overview of the regulation pertaining to the development process, registration, and approval procedures for vaccines, particularly in India, along with their brief history.

Since 1990 the effort for unification has been active in each department of our society. But the study for health policy in Unified Korea has been scarce. Unified Korea should be a democracy and a constitutional state. So we should have lively discussion on the health law as well as unified general laws. The purpose of this study is to compare the health law of South Korea and North Korea and to understand the differences in them. We guess both Korea are considerably different each other. But this study found out that there are many health related laws that have same goals and contents. The reason for this is that both health laws have its root in Korea Law. And the right to health is the social basic right. whose characteristic can not be compatible with market economy and demands state intervention for securing the right to health. The health related laws are divided into 4 fileds. 1. There is a field A which is affected by unified political and economic system and differs little from the law system: the license system of medical personnel. 2. There is a field B which is seldom affected by unified political and economic system and differs little from the law system: the right and duty of medical personnel. quarantine law. 3. There is a field C which is affected by unified political and economic system and differs greatly from the law system: health institution law(exclusive of quarantine law), the laws of medical personnel category, of research center(especially per-mission, registration and establishment). of the role of basic health in private and public area. 4. There is a field D which is seldom affected by unified political and economic system and differs greatly from the law system: health equipment law(the laws of drugs, of cosmetics and of medical instrument. of blood management). the laws of health knowledge. of cooperation in chinese medicine and western medicine. the health promotion law. the rules of first-aid. the law of separation of dispensary from medical practice. The laws which are seldom affected by political and economic system can be consolidated. which in turn can be revised and enacted before unification of Korea through the interchange between North Korea and South Korea and the support to North Korea health system.

3-dimensional Neuronavigator, Viewing Wand(ISG Technologies, Toronto, Cannda) is the surgery aid equipment for real time image (CT or MRI) guided surgery. The assurance of spatial accuracy of this system is important for clinical application. In this study, we have designed the acrylic brain phantom and measured the spatial error with that phantom. The phantom has designed to have capability to simulate image guided surgery. The phantom has 22 vertical rods whose diameters are 5mm and each rods has different length. CT scans were performed by 2.0mm slice and reconstructed for 3-Dimensional analysis. End point of rods can be obtained using reconstructed 3- Dimensional images and they are compared to actual position data. Average deviation was less than 2mm for various situations. Spatial error of Viewing Wand is acceptable in the clinical points of view, while cosmetics of the software needs to be modified to more user friend. Better accuracy can be expected when we apply the mixed fiducial fit registration and surface fit registration method. And even better results can be obtained if registration points distributed even and symetric around the target.
