The hair designers are fashion leaders who affect hair color of people. Therefore, the purpose of this study is to give some tips to satisfy customers through surveying hair designers most like color and the criteria of products choice. To have practical result, I use survey method. I took 120 hair designers who work for Park Jun beauty salon for the survey data. Among these data, I used 103 for the final data of analysis. The results are following, male hair designers like natural brown and blue coral color for hair coating. In addition, they like black color for coloring. Female hair designers like much more various color, they like orange color for coating and natural brown for coloring. Hair designers much more satisfied for international brand goods in all criteria except price. All of hair designers have favorite goods for the quality and brand image. Therefore domestic brands need much more effort to improve quality and its brand image.

Tissue engineering is an emerging, innovative technology to improve or replace the biological functions of damaged tissues and organs. Scaffolds are important materials for tissue engineering as they support cell attachment, migration, and differentiation. Marine sponges naturally contain scaffolds formed by extracellular matrix proteins (collagen and sponging) and strengthened by a siliceous or calcium carbonate skeleton. Coral skeletons are also derived naturally formed by essential calcium carbonate in the form of aragonite, and are similar to human bone. In addition, collagen extracted from jellyfish is a biosafe alternative to bovine and porcine collagen and gained attention as a potential source for tissue engineering. Moreover, cuttlefish bone is an excellent calcium source and can be used to generate bio-synthetic calcium phosphate. It has become a natural candidate for biomimetic scaffolds. This review describes the use of natural products derived from marine invertebrates for applications in bone tissue engineering based on studies from 2008 to 2014.

Rural communities have been isolated from social and economic changes underway in the broader society. Trends towed an urbanized society have depopulated many rural areas (Flora, et al, 1992). The South Korean government has targeted efforts toward an urban centered economic development policy, which has neglected the rural areas. The South Korean government also has indoctrinated rural community development with a quick-fix approach. Self-directed economic organizations based in rural South Korea began to emerge in the late 1980s. Since the 1980s, South Korean agricultural sectors have been overshadowed by globalism. McMichael (1996) stated that rural communities have two options. A immunity should either End its niche (i.e. the commodities or products that can have advantages in the international trade market) or protest against globalism to survive if rural communities fail to find a niche under globalism. South Korean neat communities did not have enough natural resources nor enough money to invest for their rural community economic development programs. These limitations made it difficult for South Korean coral communities to compete in a global economic environment. Israel, Coleman, and Ilvento (1993) stated that local leadership is a critical component in the ability of communities to respond to lang-standing problems and emerging needs. Swinth and Alexander (1990) asserted that rural leaders are critical actors in rural community development. Whether rural communities succeed in finding their niche or not, the role of rural community leaders is important for rural communities to find ways to cope in the international agriculture market.

Marine organism extracts were prepared from 26 species of Korean indigenous marine organisms, including 25 species belonging in class Anthozoa of phylum Cnidaria and a species belonging to subphylum Urochordata of phylum Chordata, and screened their inhibitory effects against ${\mu}$-calpain. As a result, the thirteen extracts were found to be active in the criteria of $IC_{50}$ < 100 ${\mu}g/ml$. Among them, the MeOH extracts of Plexauroides praelonga and Alveopora japonica showed remarkable ${\mu}$-calpain inhibitory activity with $IC_{50}$ values of $4.62{\pm}0.22$ and $4.82{\pm}0.07{\mu}g/ml$, respectively. In addition, chemical investigation of A. japonica led to the isolation of an active compound, hexadecyl tetradecanoate, as a selective cathepsin B inhibitor ($IC_{50}=9.05{\pm}2.45{\mu}M$). This compound was isolated as constituent of A. japonica for the first time in the present study.

Since ancient times, various herbal medicines have been used in folk medicine to treat a variety of diseases. While the majority of drugs belong to the Kingdom of Plantae, some drugs from the Kingdom of Animalia are listed in various Materia medica of alternative medicines. Animal-derived drugs are mentioned in the Unani system of Medicine (USM) and have been used successfully to treat a variety of diseases. Marjān (Corallium rubrum) is a vital marine drug of animal origin that has been used in USM since ancient times and continues to be used today. It possesses a variety of beneficial pharmacological properties, including tonic effects on the heart, brain, stomach, and eyes, pregnancy protection, expectorant, and hemostyptic properties. It is used to treat hemoptysis, palpitation, bleeding piles, hemiplegia, heart failure, and general weakness. It is also an ingredient in a variety of Unani formulations with pharmacological significance. Unani physicians expanded the uses of Marjan and successfully used it to treat a variety of new diseases. There is a dearth of scientific research on its pharmacological and medicinal properties. The urgent need is to validate the Unani claims about its beneficial cardiac and nervine actions, as well as other significant actions mentioned in the Unani literature.

The Cat Ba Islands in Hai Phong City, northern Vietnam, consist of a large limestone island with a maximum height of 322 m above sea level and 366 small limestone islets with a total area of about $180\;km^2$. The islands are relicts of karst limestone mountains that became submerged during the Holocene transgression 7000 - 8000 year ago. The combination of the longtime karst process and recent marine processes in the monsoonal tropical zone has created a very diversity landscape on the Cat Ba Islands that can be divided into 3 habitat types with 16 forms. The first habitat type is the karst mountains and hills, including karst mountains and hills, karst valleys and dolines, karst lakes, karst caves, and old marine terraces. The second habitat type is the limestone island coast, including beaches, mangrove marshes, tidal flats, rocky coasts, marine notch caves, marine karst lakes, and bights. The third habitat type is karst plains submerged by the sea, including karst cones (fengcong) and towers (fengling), bedrock exposed on the seabed, sandy mud seabed, and submerged channels. Like the landscape, the biodiversity is also high in ecosystems composed of scrub cover - bare hills, rainy tropical forests, paddy fields and gardens, swamps, caves, beaches, mangrove forests, tidal flats, rocky coasts, marine krast lakes, coral reefs, hard bottoms, seagrass beds and soft bottoms. The ecosystems on the Cat Ba Islands that support very high species biodiversity include tropical evergreen rainforests, soft bottoms; coral reefs, mangrove forests, and marine karst lakes. A total of 2,380 species have been recorded in the Cat Ba Islands, included 741 species of terrestrial plants; 282 species of terrestrial animals; 30 species of mangrove plants; 287 species of phytoplankton; 79 species of seaweed; 79 species of zooplankton; 196 species of marine fishes; 154 species of corals; and 538 species of zoobenthos. Many of these species are listed in the Red Book of Vietnam as endangered species, included the white-headed or Cat Ba langur (Trachypithecus poliocephalus), a famous endemic species. Human activities have resulted in significantly changes to the landscape end ecosytems of the Cat Ba islands; however, many natural aspects of the islandsd have been preserved. For this reason, the Cat Ba Islands were recognized as a Biological Reserved Area by UNESCO in 2004.

Symbiodinium is a dinoflagellate genus that coexists with coral reefs and is known to provide ultraviolet (UV) protection in nature through the synthesis of mycosporin-like amino acids (MAA). In order to develop a natural and ecofriendly sunblock for use in summer resorts, the possibility of using a Symbiodinium microbiome extract or an MAA was investigated. Two sunblocks, one containing 7% Symbiodinium extract and the other containing MAA were prepared to be tested on hairless mice and human skin. In this clinical study, the sun protection factor (SPF) and Protection factor of UV A (PFA) values of the sunblock containing either Symbiodinium extract or MAA were determined. The SPF values of the sunblock containing Symbiodinium extract and MAA were 10.43 and 10.83, respectively, and the PFA values were 3.42 and 3.39, respectively. Based on their PFA values of ≥2, the UV A protection can be graded as PA+ (low) for both the sunblocks. In addition, the UV-blocking extract of Symbiodinium has a low phototoxicity and cytotoxicity, reducing the possibility of a heavy feeling to the skin or a foreign-body sensation caused by residue build-up. The low toxicity feature of the major sunblock component will also prevent side effects, such as allergic reactions. Although Symbiodinium extract or MAA alone do not provide effectiveprotection against UV irradiation, their protection capacity can be complemented by the addition of inorganic UV-protecting compounds.

The Abrolhos Continental Shelf (ACS) encompasses the largest and richest coral reefs in the southern Atlantic Ocean. A taxonomic study of non-geniculate coralline algae (NGCA) from the region was undertaken using both morpho-anatomical and molecular data. Specimens of NGCA were collected in 2012 and 2014 from shallow reefs of the ACS. Phylogenetic analysis was performed using dataset of psbA DNA sequences from 16 specimens collected in the ACS and additional GenBank sequences of related NGCA species. Nine common tropical reef-building NGCA species were identified and described: Hydrolithon boergesenii, Lithophyllum kaiseri, Lithophyllum sp., Lithothamnion crispatum, Melyvonnea erubescens, Pneophyllum conicum, Porolithon onkodes, Sporolithon ptychoides, and Titanoderma prototypum. A key for species identification is also provided in this study. Our molecular phylogenetic analyses suggest that Lithophyllum sp. corresponds to a new species. Our study also confirms that Lithophyllum kaiseri is a new record in Brazil. The psbA sequences of Lithophyllum kaiseri and Melyvonnea erubescens matched with type specimens indirectly. The taxonomic identification of the remaining species was supported by morpho-anatomical evidences as DNA sequences of their types or topotypes remain unavailable.
