Namakshin(: Wooden clogs), also called keukja, moklee, or mokhye usually have high heels to be worn on rainy days. According to the "Hamel's Journal and a description of the Kingdom of Korea, 1653-1666", a book authored by Hendrick Hamel (1630-1692), the 33 crew members of the S/S Sperwer were interned in March 1656 under the jurisdiction of the "Pyongsa" (Commandant) in Pyongyong, Kangjin and they were instrumental in making clogs of their native country and sold them to people around the Pyongyong area to earn some extra money. Pyongyong & Gangjin's wooden shoes are clearly different from those produced in the rest of Korea and bear striking resemblance to traditional Dutch clogs (klompen in Dutch). According to Hamel's narratives, the Dutch captives made wooden shoes for a living in Jeonlla province. Namakshin in Chosun was divided into 5 type, woman's rubber shoes, Condora, Taesahye, Balmaksin, trough style.

Hamel has a scholastic value as the first person, who announces Jeju and Korea to Europe. However, there has been little research on developing digital contents except a few books about Hamel. We develop an educational game on PDA using Hamel, based on Hamel character, Jeju's unique culture, multimedia technology, and so on. Compared with the previous games, it is different from the form of gathering points and has various game scenarios through interactions between Hamel character and game space. The structure of this game, which connects Jeju culture and cyber space together, represents the form of a digital storytelling. You can study through this game. It uses quizzes about Jeju culture, crossword puzzles, finding a sequence, finding differences between two pictures to teach users, and fixing pieces of a figure, etc. When we made the game, we divided it into some independent modules to make new game series easily using contents of the other provinces.

In this study, based on Choi, Jong Rim's script (2000), the main characters' stage costume designs were presented with 15 illustrated pieces in terms of compounding the images of Korea and West. I considerered the main characters' social status and personality by each act and scene, as well as the correlation of the stage costume's minor theme, color and material. In expressing the stage costume, this study has chosen the formational method of the comparative design dimensions between costumes in 1650s Joseon and baroque period and used the joinder of flat pattern and draping in various parts of the costumes.

The establishment of differentiated place image is becoming more important as a cultural tourism development policy in order to secure regional identity and boost regional economy. Place marketing strategies using culturally and historically differentiated regional places is very valuable as part of a regional development strategy to strengthen regional competitiveness. To construct place image as a differentiated brand, place image positioning suitable for a specific place and region needs to be established and comprehensive marketing strategies are required to generate various synergy effects. Based on existing theories and discussions regarding place and place marketing, this study is aimed at seeking for possibility as a cultural activity space and its more efficient use plans by selecting a region which has historical and cultural backgrounds and assets about Hamel's drift and stay. For these purposes, this study investigated historical and cultural backgrounds through a case study and made suggestions about brand making and place image promotion. In addition, this study aimed to examine efficient plans and utilization possibility for comprehensive image construction.

A.H.Hamel proved the Ekeland's principle in a locally convex Hausdorff topological vector spaces by constructing the norm and applying the Ekeland's principle in Banach spaces. In this paper we show that the Ekeland's principle in a locally convex Hausdorff topological vector spaces can be proved directly by applying the famous general principle of H.Br$\acute{e}$zis and F.E.Browder.

The purpose of this study is to know how to utilize foreigners such as Weltevree and Hamel who visited Korea in the pre-modern period, during history class. Both Weltevree and Hamel were Dutch men, and the first person who visited the Joseon Dynasty was Weltevree. He was a sailor of the Dutch East India Company, landed on Jeju Island in 1627, and since then, he did not return to his country. He played a major role in the execution of weapons. Hammel, the merchant catcher of the Dutch East India Company, traveled to Joseon in 1653 and contacted several kinds of people in various parts of the country for 13 years, and was able to survey the scenery and customs of Joseon. It can be difficult for students to understand the overall trends of the world history and the views of the East and the West because students learn from Western history, East Asian history, and Korean history, separately. Learning characteristics associated with East-West exchanges will enable students to understand the Western and Eastern history of the West, and understand the history of the world.

This paper describes a visual tracking control law of an Unmanned Aerial Vehicle(UAV) for monitoring of structures and maintenance of bridges. It presents a control law based on computer vision for quasi-stationary flights above a planar target. The first part of the UAV's mission is the navigation from an initial position to a final position to define a desired trajectory in an unknown 3D environment. The proposed method uses the homography matrix computed from the visual information and derives, using backstepping techniques, an adaptive nonlinear tracking control law allowing the effective tracking and depth estimation. The depth represents the desired distance separating the camera from the target.

Characterization of special nuclear material may be performed using energy spectroscopy of either the neutron or gamma-ray emissions from the sample. Gamma-ray spectroscopy can be performed relatively easily using high-resolution semiconductors such as high-purity germanium. Neutron spectroscopy, by contrast, is a complex inverse problem. Here, results are presented for $^{252}Cf$ and PuBe energy spectra unfolded using a single EJ309 organic scintillator; excellent agreement is observed with the reference spectra. Neutron energy spectroscopy is also possible using a two-plane detector array, whereby time-of-flight kinematics can be used. With this system, energy spectra can also be obtained as a function of position. Spatial-dependent energy spectra are presented for neutron and gamma-ray sources that are in excellent agreement with expectations.

Taxonomic account is given to the five species of Scytosiphonaceae, Colpomenia peregrina (Sauvageau) Hamel, Endarachne binghamiae J. Agardh, Hydroclathrus clathratus (C. Agardh) Howe, Petalonia fascia (O. F. Muller) Kuntze, and Scytosiphon lomentaria (Lyngbye) Link, collected from Ullungdo Island, Korea. C. peregrina, introduced for the first time in Korea, is similar to C. sinuosa (Roth) Derbes et SolieI in outer appearance but is distinguished by absence of cuticle over the plurilocular sporangial sori. E. binghamiae accords well with American plants but varies in height and width of the thallus according to seasons. H. clathratus has small cortical cells and large clear medullary cells. P fascia is characterized by one to two celled small cortical layer and two to four celled large medullary layer. S. lomentaria shows variation in gross morphology, especially in height and width of thallus according to seasons.easons.

Organizations have realized the importance of CRM. To obtain the maximum possible lifetime value from a customer base, it is critical that customer data is analyzed to understand patterns of customer response. As customer databases assume gigantic proportions due to Internet and e-commerce activity, data-mining-based market segmentation becomes crucial for understanding customers. Here we raise a question and some issues of using single SOM approach for clustering while proposing multiple self-organizing maps approach. This methodology exploits additional themes on the attributes that characterize customers in a typical CRM system. Since this additional theme is usually ignored by traditional market segmentation techniques we here suggest careful application of SOM for market segmentation.
