The Plastic material had been developed in the middle of the 19th century as an alternative material. Along with the development of the electrical engineering industry, it cropped up into center stage as an effective material and has increasingly expanded its use. As such, the plastic material has bound deep-seated ties with the design activities of industrial products, coming into the main material for a variety of industrial designs. Despite its dose affinity to design function in terms of its materialistic property, we have rarely seen examples of intensive study on the realtionship between plastics and designs. This study aims to find the importance that the substance affects industrial products in designs along with the development of plastic materials. With the objective in mind, we made a review of the streamline stylishness that had flourished in the twenties and thirties of the 19th century. Through this study, we understand that the plastic material has a close realtionshop with design activities in three different aspects. First, its amorphous state of nature makes it possible to change into any shape one desires in plastic surgery, which feature in turn influences the moulding of any design forms. Second, the plastic material is best suited to mass-manufacture, which induces to reduce the cost of production. Hence, the expansion of design industry. Third, the plastic material allows the multiple variety of colors, sensitivity, gloss and patterns and infinitely large possibility ranging from natural senses to human senses with the result that numberless diversity of designs cdould come into being.

Purpose: Aquacel Ag$^{(R)}$ is a hydrofiber wound dressing integrated with ionic silver. Sorbact$^{(R)}$ is a hydrophobiccoated dressing that uses the hydrophobic interaction with microbes. In this study, we compared the wound healing effects and the antibacterial effects of Medifoam$^{(R)}$, Betadine soaked, Aquacel Ag$^{(R)}$ and Sorbact$^{(R)}$ dressings against MRSA-infected wounds. Methods: Eighty rats were divided into four groups: Medifoam$^{(R)}$; Betadine soaked; Aquacel Ag$^{(R)}$; and Sorbact$^{(R)}$. A $1.5{\times}1.5cm$ square full-thickness wound was made on the dorsum of each rat and infected with MRSA. Twenty-four hours thereafter, each dressing was applied to the wound and changed every other day. One, 3, 7, 11 and 15 days after the wound infection, swab culture grade, wound bed appearance score, and wound defect size change were evaluated, and 7 and 15 days after, histologic evaluation was compared between the groups. Results: The bacteria load of wounds in the Sorbact$^{(R)}$ group decreased earlier than in the other groups. The wound bed appearance score of the Sorbact$^{(R)}$ group also increased quicker, compared with the other groups. However, the size of wounds of the Aquacel Ag$^{(R)}$ group decreased more rapidly, compared with other groups. From the histologic point of view, there was no significant difference between Betadine soaked, Aquacel Ag$^{(R)}$ and Sorbact groups. Conclusion: The hydrophobic dressing using Sorbact$^{(R)}$ showed a more rapid reduction in the MRSA load and an elevation in the wound bed appearance score, but a slower decrease in wound size change due to detachment of wound bed tissue when the dressing was eliminated in the low exudate wound. The silver-containing hydrofiber dressing using Aquacel Ag$^{(R)}$ was more effective in ultimate wound size reduction, but some debris was trapped in the wound tissue and induced foreign body reaction in the high exudate wound. Thus, ongoing selection process of treatment based on the evaluation of the infectious wound state will be very important.

Purpose: The purpose of this study is to estimate muscle defect by ultrasonography in the patients with secondary deformities of the lip. We investigated the association between the muscle defect in the repaired cleft lip and the philtral appearance not only at resting state but also maximal puckering. Methods: From December 2006 to November 2007, 52 children were evaluated after primary or secondary cheiloplasty. Digital photographs were taken both from the front and both three quarter views in repose and at maximal pucker. Video clips were also taken in repose and at maximal pucker. A panel of four, scored the philtral ridge and dimple seen on these photographs and videos by using two visual analog scales. Eminence of the philtral ridge was scored by a 5 point grading scale, from "conspicuous groove" to "normal philtral ridge" and the philtral dimple was scored by 3 point grading scale, from "no dimple" to "prominent dimple". Ultrasound images of the upper lip were made using a linear array transducer at the resting position of the lip and evaluated by a single radiologist. Results: The philtral ridge eminence scored $2.79{\pm}0.54$ and $1.40{\pm}0.53$ at resting and maximal pucker, correlating with "flat" and "conspicous groove". The philtral dimpling scored $1.44{\pm}0.53$ and $2.27{\pm}0.66$ at resting and maximal pucker, correlating with "no dimple" and "slight dimple". Ultrasound imaging showed the average muscle dehiscence to be $3.78{\pm}2.14$ mm at resting position. Correlation between the muscle defect in ultrasound imaging and philtral ridge eminence at rest was statistically significant (p<0.050), but was not significant (p=0.756) at maximal pucker using Spearman's rank correlation. Correlation between the muscle defect in ultrasound imaging and philtral dimpling was not statistically significant both at rest (p=0.920) and at maximal pucker (p=0.815) using Spearman's rank correlation. Conclusion: Quantitative assessment of the muscle defect using ultrasonography correlates with the static philtral appearance, but does not correlate with the dynamic appearance. Also, the size of the muscle defect does not show any correlation with the philtral dimpling. Our findings reveal that ultrasound imaging partially reflect static appearance of philtrum but cannot reflect dynamic appearance and suggest the need for further research to evaluate dynamic appearance.

Purpose: In cases where nasal fractures involve frontal process of maxilla or perpendicular plate of ethmoid, 4 - 5 days of nasal packing may not provide sufficient support for avoiding displacement after packing removal. Therefore a single Kirschner - wire(K - wire) is used as an internal splint when nasal fractures involve the above two areas. Methods: Thirty five patients during the last 3 practical years were treated with a K -wire pinning according to the anatomic locations of nasal fractures. We performed a retrospective study using 13 nasal fractures out of total 35 patients. Among 13 cases, 10 patients involved frontal process of maxilla, and 3 patients were diagnosed as bilateral nasal side wall fractures accompanied with fractures of perpendicular plate of ethmoid. One patient of the last three cases had been augmented with dorsal silicone implant long before the trauma. We analyzed the anteroposterior displacement of key stone area and the width between both lateral walls by comparing immediate postoperative radiographs with 2 month follow - ups. To reduce the errors, the same measurements were taken by two different inspectors, and the mean of each inspector's measurements was compared. Patient satisfaction was analyzed using a questionnaire regarding the esthetic and functional outcomes. Results: Ten patients underwent a longitudinal K - wire fixation in submucoperiosteal plane underneath the frontal process of maxilla. And three patients underwent a transverse K - wire fixation from the one side of lateral wall to the perpendicular plate of ethmoid and to the other side of lateral wall. The mean postoperative anteroposterior displacement of the key stone area measured by two inspectors were 1.84% and 3.06%; mean narrowing of bony pyramid were 1.33% and 1.48%, respectively. Subjective satisfaction scores regarding the esthetic appearance and the maintenance of nasal shape compared with immediate post - operative state with the long term ones were not different (p>0.05). Conclusion: K - wire pinning after closed reduction is a reliable and useful method for the treatment of nasal fractures involving frontal process of maxilla or perpendicular plate of ethmoid. This is because it achieves longer intranasal support after reduction. This method also leaves conspicuous external scar, and minimal soft - tissue injury.

Purpose: In most cases of nasal bone fracture, closed reduction with internal or external splint fixation approach is selected. However, because of indiscriminate insertion of the internal splint without considering of anatomical difference or deformity, insufficient fixation happens frequently that need additional fixation. Therefore, we suggest a new method for providing adequate support in reduced nasal bone by carving $Merocel^{(R)}$ that is fixed for the anatomical structure. Method: Closed reduction and internal fixation with carved $Merocel^{(R)}$ was performed in 15 nasal bone fracture patients from March, 2010 to July, 2010. Each patient was evaluated by physical examination, facial photographic check, simple X-ray, and computerized tomography. On the first day post-operation, location of packing and amount of reduction were checked by follow up X-ray and computerized tomography. In addition, patients' symptoms were evaluated. During the 3-month post-op follow up at out-patient clinic, operator, 2 doctors in training and one assistant performed the objective evaluations by physical examination on nasal dorsal hump, nasal deviation, nasal depression, nasal breath difficulty, and nasal airway obstruction. A survey of subjective patients' satisfaction in 4-stages was also performed. Results: The results of follow-up computerized tomography of the 15 patients revealed that 11 patients had good reduced state. Three patients with combined maxillary frontal process fracture had over reductions. A survey performed on the first day post-operation showed that 14 of 15 patients answered that their current symptoms were more than tolerable. At the 3-month follow-up physical exam, one case had a dorsal hump. However, there were no nasal deviations, nasal depressions, nasal breath difficulties, or nasal airway obstructions. Twelve of the 15 patients answered more than moderate on the 3-month survey. Conclusion: Intranasal packing after carving the $Merocel^{(R)}$ considering anatomical structure is a new effective method to promote proper-reduction, maintain stability, and minimize patients' symptoms by addition of a simple procedure.

This paper illustrates the process of Japanese invasion of Joseon. In the December of 1905, specifically, Japan established the Residency-General in order to reform systems of government and to control records. Japan founded the Residency-General to reinforce the internal affairs of Joseon. Then, they reorganized systems of government using Joseon's bureaucracy system. The reorganization facilitated control of current and non-current records. After all, this helped Japan to know the actual circumstances of Joseon and the invasion of Joseon. To be specific, Japan organized the records at the Kyujanggak, an imperial library of the Joseon Dynasty, for understanding historical records and dominated Joseon government's current records for comprehending vulnerability of Joseon. On the other hand, Japan invaded Joseon by justifying their actions as 'administration improvement' and 'reformation'. Here are the actual examples. First, the Residency-General dominated the Kyujanggak and reorganized historical records which were stored there. It lasted for two years and let Japan comprehend the course of Joseon history. Second, the Residency-General collected and arranged current records of Joseon. It was buckled down in the August of 1910, when the Great Han Empire collapsed. After the fall of the Great Han Empire, the Residency-General transferred government records from the Japanese Government-General of Korea in order to understand the state of Joseon. Last, the Residency-General arranged records on both governmental and the Imperial property, then most of them reverted to national property.

The Design Society of Korea. It is our urgent task that we should map out our detailed guiedlines for the improvement of export-oriented industries and of the design of export goods in preparation for our export goal of $30 billion in the upcoming 1980s. The government, university design researchers, and most entrepreneurs have confronted diverse kinds of racking issues: how much do most export industries take advantage of the indus-trial design for the improvement of the quality of export goods\ulcorner, structural defects of most export industries, chronic and vicious cycle of overlooking the value of the industrial design in the process of manufacturing export goods and etc. In other words, the recent trend of slighting the industrial design is to speed up the sales of only unsophisticated goods on the international markets. Although Koreans have been plagued by scantiness of natural resources under these circumstances, most Korean people have showed off their strong will for today's growth. Furthermore, most exporters should do their best to sweep overseas markets by manufacturing sophisticated goods outranking those commodi-ties made by the United States, Japan, West Germany and the other developed countries. In this respect, we have to make our best efforts for the expensive application and practical use of the industrial design, one of the comprehensive sciences, in the face of the hard realities and conditions which we have confronted until now. For example, it can be attributed to the practical application of the industrial design that the neighboring Japan, West Germany, France, the United Kingdom in Europe, and the United States in North America have formulated a highly advan-ced cultural zone and braced up for their own trade protection-ism and tightened their embargoes on EEC goods. Unless any export goods take the best advantage of the industrial design, one of the behavioral sciences capable of satisfying the material mental needs of modern men and of promoting cultural growth, I am convinced that they will not infiltrate into any countries that have enjoyed their own highly cultural lives. It is absolutely important that most Korean universities, state-run, private corporations and research institutes should work out the improvement strategy for the development and practical use of the industrial design as will as the revision of the present curricula of the departments of design. However, most design researchers have come to grips with several difficult problems such as the correlation of export oriented industries and the industrial design and the development of the design of export goods. The improvement of the industrial design is our urgent assignment that we have to solve in the 1980s. Accordimgly, I cannot too much emphasize the value the recognition of the industrial design in our industrial communities because we have never witnessed the prosperity of those countries which have taken little notice of the importance of the industrial design. Hopefully, most entrepreneurs will take much consideration of the value of the industrial design and then can defeat their rival businessmen on the international markets by exporting goods of highly sophisticated design. In this respect, the main purpose of the research paper which this society presented is to underline the fact that the improvement and development of the industrial design is our common assignment to be studied from the viewpoints of national dimension as well as in conformity with our immediate goal for the export-oriented prosperity of state. In conclusion, I would like to highlight the fact that our export goods shall be continually developed in pace with the correlative improvement of the indudtrial design so as to pave the way for their bright prospect and to enhance their best impression of the first-class goods on the international markets.

The purpose of this article is to analyze the standings of working-level officials belonging to Jongbusi (Court of the Royal Clan) holding the rank of "jeong" and below between the 18th and mid-19th Century. Jongbusi, which was headed by a Grade-3 official, was in charge of the compilation of royal genealogy and supervision of royal relatives. During the late Joseon Period, its officials were composed of its chief, jeong, jubu (Grade-6 official), and jikjang (Grade-7 official). By 1864, it was incorporated into Jongchinbu (Office of the Royal Relatives). Jongbusi nangcheong seonsaengan (Register of Staff Officials at the Court of the Royal Clan), which is preserved at the Jangseogak Archives of the Academy of Korean Studies, lists the officials who served at the office between 1794 and its incorporation into Jongchinbu in 1864. The register also includes the officials' ranks, names, DOBs, family clans, their ranks in the offices they were transferred from, their ranks in the office they were transferred to, etc. Those interested view it as a precious relic that provides valuable information on the officialdom of the dynasty. A majority of the officials who served at Jongbusi were those who passed the higher civil service examination. Many of them at the level of jikjang were those who passed the licentiate examination. Their designation as an official was part of the "muneum" system, which granted official posts to descendants of those who accomplished a distinguished service for the country or served as a high-ranking official. They were those transferred from equal or lower positions in another office. Many of jubu-level officials of Jongbusi were those transferred from honorable and important posts of other offices or local administrative offices. Many of jikjang-level officials of Jongbusi were those who previously served as dosa (assistant officials) at Uigeumbu (Bureau of Crime Investigation) headed by a Grade-1 official. The officials' transfer to an office with a lower position like Jongbusi appears to have been for the provision of placing them in working-level positions rather than letting them remain in positions only carrying an honorary title. As for the transfer of officials of Jongbusi to other offices, many of those with the rank of jeong were transferred to lower positions. Supposedly it was because not many Grade-3 positions were vacant. Many of them were transferred to honorable and important posts. Some of them were also transferred to positions at local government offices, supposedly to avoid an excess of personnel at the central government. Those at the level of jubu or jikjang of Jongbusi were transferred to equal or higher posts in other offices. Particularly, most of those holding the position of jikjang (Grade-7) were transferred to higher posts. The family clan that produced the largest number (10%) of Jongbusi officials was the Jeonju Yi Clan, which produced the largest number of those who passed the higher civil service examination. It was also found that the top 20 family clans produced about half of the entirety of Jongbusi officials. According to the aforesaid Jongbusi nangcheong seonsaengan, about 90% of the cases of promotion of Jongbusi officials occurred after the revision of Seonwon boryak (Royal Genealogy of the Joseon Dynasty). It is speculated that the supervision of royal family members, one of the two leading functions assigned to Jongbusi, was suspended in the late Joseon Period. The relevant function does not appear even in chronicles pertaining to the Joseon Dynasty. The reason being had something to do with the sharp decrease in the number of royal family members during the reign of King Injo (r. 1623-1649). Their number was decreased to the extent that royal ceremonies could not be adequately carried out. Naturally, the meaning of supervising royal family members faded. Witnessing such a sorry state of the royal family, Heungseon Daewongun, King Gojong's father who served as the regent, incorporated Jongbusi into Jongchinbu in an effort to enhance the status and authority of the royal family.

An investigation by KRNIC (Korea Network Information Center) on the real state of usage of internet has shown that 96.9％ of children investigated had experiences of using internet. Especially the firstly ranked item that had been answered by children as a necessity of internet was 'Studying to solve tasks' rated by 83.9％. As seen from the research result, the need as a homework sonics is actually so dominant that it cannot be ignored when considering the profitability at the area of education contents, but any profound research has not been accomplished yet. Internet has been positioned as a more effective and fruitful learning tool, and also all activities done by users for exploring informations and choosing learning items under the on-line circumstances are based on the successive mutual reactions between users and computers. Up to now much of the web based learning circumstances has been introducing the User Interface using metaphor, and the same is found dominantly from the sites for children. But in spite of the availability of metaphor mentioned above the current status is much lack of profound researches about metaphor interface; and what is more, in the case of the site for elementary school students the gap of the ability recognizing metaphor is very large between lower classes and higher classes according to the degree of mental growth but that is used to be simply ignored, then a common concept is adapted to interface for all grades of classes and moreover for infant and kindergarten without any objections. Based on foregoing problems this research has put the main focus on the groping and presenting desirable directions on the prospect design of interface for children-oriented sites by analyzing the status of practical usage of metaphor interface in the field of the sites for children-oriented learning sites with concentration upon homework supporting domains.
