Namdaemun Market is located in the heart of history and has the volume and the budget for nearly half of the total Namdaemun. But it has been undergoing the crisis of stagnation without reviving the merit of only the 'jewelry' wholesale industrial cluster in the nation. The purposes of this study were that analyzed the status and design of jewelry in Namdaemun and identified the characteristics of successful domestic jewelery brands and then the revitalized the way of the Namdaemun jewelry industry. Problems being currently facing the Namdaemun jewelry shopping are most likely caused by products' design did not respond to changes quickly, while China's jewelry products are in leaps of the quality and the affordable jewelry market in Korea has lost the large number of the customers by china's cheap jewelry products. The most feature of successful domestic jewelry companies, Red Eye, Naughty Cat and Jackie Moon. put the most effort to unique design development and then constantly develope new designs to meet the diverse needs of consumers. It is a conclusion that the Namdaemun jewelry market need to produced under the name of brand not by the traditional whole sale market style. Development unique jewelry brand requires a high-end commercial strategy of the logo, packaging and interior. The high-end quality require for the advanced designs as well as the study of new materials needed for the advanced materials.

2008 began with the American financial crisis which gave way to the liquidity crisis (Fannie Mae and Freddie Mac) situation in which 'the withdrawal of investment initiated from the insufficiency of the U.S. subprime mortgage loan companies', 'the large size loss situation of the financial company (Bear Stearns) due to the American structured bond insufficiency' and the second half opening part national debt mortgage company. Within the American financial crisis was propagated the crisis of international derivatives. Due to this, the withdrawal of foreign investment progressed in the interior of a country with the considerable. By the end of 2007, the exchange rate fluctuation was absorbed in the domestic financial circle on the belief the potentiality of the domestic financial market had been growing drastically through the expansion of the foreign currency debt according to this and it came to the defence but while the exchange rate jumped up to the dollar shortage according to the international crisis, the small and medium companies making the banks and exchange rate-related derivatives contract were going bankrupt due to the derivatives loss. The small and medium factories establish the bank exchange rate-related derivatives has nose (KIKO), pivot (PIVOT), and snowball (Snowball) etc. at that time and the damage which it is the KIKO grasped at 6 end of the months in 2008 caused by reaches to 1 thousand billion 4 thousand hundred million dollars. Small and medium companies in which the dollar which it has to denounce among small and medium companies bearing the KIKO contract in fact with the Knock-In generation city bank exceeds the amount of sales were known to be 68 enterprises among 480 enterprises. This paper departs in this awareness of a problem and tries to look into the risk factor of the derivatives, including nose and study the essential ring risk management plan of small and medium manufacturer.

This paper presents a method of seismic analysis for a cylindrical liquid storage structure considering the effects of the interior fluid and exterior soil medium in the frequency domain. The horizontal and rocking motions of the structure are included in this study. The fluid motion is expressed in terms of analytical velocity potential functions, which can be obtained by solving the boundary value problem including the deformed configuration of the structure as well as the sloshing behavior of the fluid. The effect of the fluid is included in the equation of motion as the impulsive added mass and the frequency-dependent convective added mass along the nodes on the wetted boundary of the structure. The structure and the near-field soil medium are represented using the axisymmetric finite elements, while the far-field soil is modeled using dynamic infinite elements. The present method can be applied to the structure embedded in ground as well as on ground, since it models both the soil medium and the structure directly. For the purpose of verification, earthquake response analyses are performed on several cases of liquid tanks on a rigid ground and on a homogeneous elastic half-space. Comparison of the present results with those by other methods shows good agreement. Finally, an application example of a reinforced concrete tank on a horizontally layered soil with a rigid bedrock is presented to demonstrate the importance of the soil-structure interaction effects in the seismic analysis for large liquid storage tanks.

The effects of electron beam (EB) irradiation on the superconducting critical temperature ($T_c$) and critical current density ($J_c$) of YBCO films were studied. The YBCO thin films were irradiated using a KAERI EB accelerator with an energy of 0.2 MeV and a dose of $10^{15}-10^{16}e/cm^2$. A small $T_c$ decrease and a broad superconducting transition were observed as the EB dose increased. The value of $J_cs$ (at 20 K, 50 K and 70 K) increased at doses of $7.5{\times}10^{15}$ and $2.2{\times}10^{16}e/cm^2$. However, $J_cs$ decreased as the dose increased further. The X-ray diffraction (XRD) analysis showed that the c axis of YBCO was elongated and the full width at half maximum (FWHM) increased as the dose increased, which is strong evidence of the atomic displacement by EB irradiation. The transmission electron microscopy (TEM) showed that the amorphous layer formed in the vicinity of the surfaces of the irradiated films. The amorphous phase was often present as an isolated form in the interior of the films. In addition to the formation of the amorphous phase, many striations running along the a-b direction of YBCO were observed. The high magnification lattice image showed that the striations were stacking faults. The enhancement of $J_c$ by EB irradiation is likely to be due to the lattice distortion and the formation of defects such as vacancies and stacking faults. The decrease in $J_c$ at a high EB dose is attributed to the extension of the amorphous region of a non-superconducting phase.

This study analyzes the conditions and products of internet shopping malls that sell natural dyeing products. In this study, 98 natural dyeing internet shopping malls were selected. The results of this study are as follows. The locations of the internet shopping malls were Gyeonggi-do, Seoul, Jeollanam-do, Gyeongsangbuk-do, Gwang-ju (city), Daegu (city), Busan (city), Gyeongsangnam-do, and Jeju-do. The most frequent dyes of the natural dyeing products were loess, followed by charcoal, indigo, and persimmon. Indigo was most frequently used in Seoul, with loess and charcoal most frequent in Gyeonggi-do. Persimmon, indigo, loess, and charcoal were mainly used in Jeollanam-do, with persimmon and loess in the Gyeongsangbuk-do, and persimmon in Jeju-do. The highest ordered product categories were accessories, followed by adult clothing, interior decoration products, and bedding. The most frequent products were bedclothes, followed by scarves, female shirts, blouses, pillows, female jackets, and vests. Regarding the price of products, 150,000-200,000 won was the highest for the Saenghwal Hanbok, with 10,000-30,000 won for underwear, 30,000-60,000 won for accessories, and 100,000-150,000 won for bedding. Concerning product information, 58.2% of internet shopping malls offer the product size and almost half of them did not show the properties or directions for handling the product. Based on the research results, the problems of the conditions and products of natural dyeing internet shopping mall were derived. The results show that the natural dyes of internet shopping malls lacked regional symbolism, the products were not specialized, and product information was not fully offered to consumers. To solve these problems, the strategies for marketing the promotion of the natural dyeing internet shopping mall were, ‘Using natural dyes from local resources’, ‘Market oriented and specialized item design’, and ‘Offer right product information’.

A new analytical derivation of the elastodynamic point load solutions for an isotropic multi-layered half-space is presented by means of the precise integration method (PIM) and the approach of dual vector. The time-harmonic external load is prescribed either on the external boundary or in the interior of the solid medium. Starting with the axisymmetric governing motion equations in a cylindrical coordinate system, a second order ordinary differential matrix equation can be gained by making use of the Hankel integral transform. Employing the technique of dual vector, the second order ordinary differential matrix equation can be simplified into a first-order one. The approach of PIM is implemented to obtain the solutions of the ordinary differential matrix equation in the Hankel integral transform domain. The PIM is a highly accurate algorithm to solve sets of first-order ordinary differential equations and any desired accuracy of the dynamic point load solutions can be achieved. The numerical simulation is based on algebraic matrix operation. As a result, the computational effort is reduced to a great extent and the computation is unconditionally stable. Selected numerical trials are given to validate the accuracy and applicability of the proposed approach. More examples are discussed to portray the dependence of the load-displacement response on the isotropic parameters of the multi-layered media, the depth of external load and the frequency of excitation.

The need for off-site construction has increased in the construction industry in Korea in recent years due to the enforcement of the 52-hour workweek, the increasing age of workers on construction sites, the deepening dependence on overseas workers, and the stagnation of productivity in the construction industry. Thus, studies on OSC started in April 2020. In addition, as a national policy study advocating the modular construction method, which is one of the OSC methods, was completed in the first half of 2019. 70 housing units in two complexes that satisfied the Housing Act requirements have been supplied to citizens. However, although modular construction methods have been recognized as a dramatic construction method that achieves shortened construction schedules and solves the issues of cost reduction and the shortage of technical workers on sites by combining the advantages of the manufacturing industry and applying the economies of scale, realistically it has issues due to the rising cost of steel and a low pre-fabrication ratio. Moreover, the construction time of core parts, such as those built by pouring concrete, has become a factor that hinders the shortening of construction times. Thus, this study aims to propose a precast concrete(PC) modular construction system, which fuses three-dimensional infill as an interior finish material and a three-surface PC module that can acts as a structure for a construction method that is economical and can shorten construction time.

Caffe Bene, one of the most notable coffeehouse chain brands in Republic of Korea, gives us some thought-provoking issues in terms of sustainable success. Despite harsh competition among various coffeehouse brands, Caffe Bene has been accomplished astonishing outcomes in domestic market and now ranked 2^nd place in sales among the global coffeehouse franchise in 2010 and 2011. These achievements were possible mainly because Caffe Bene adopted distinctive shop design, maintained aggressive marketing strategy, developed new menu, and combined the unique Korean culture with ordinary concept of café to make its place attractive. However, since Korean coffeehouse market is getting saturated and consumers are becoming savvy about coffee, Caffe Bene needs to find a new solution to overcome growth stagnation. Besides, many experts pointed out that irrational increase in the number of stores might hurt its business in the aspect of managing distribution channel and providing consistent services. Also, customers of Caffe Bene have shown that it has to complement its critical weaknesses: inferior coffee taste and relatively high price for a cup of coffee. Especially, some people view that the company is shifting its high rental fee, interior cost and PPL marketing cost to consumers by charging high price for coffee. To get over the problems, Caffe Bene is currently using C/S Consumer Management System though experts are questioning about the efficacy because of the conflict between purpose of the system and the headquarters' plan. Present CEO Kim also announced that the company will complete its logistics system in the latter half of 2012 to provide stores with more high quality coffee beans to improve taste of coffee. Thus, in this case, we describe how Caffe Bene succeeded in Korean market and enumerate its key success factors. Also, we specify the long-term goals of Caffe Bene and introduce the current policies and strategies to show how the company is working on to achieve its ultimate goal. By reading and analyzing this business case, students could get useful insights regarding franchise management and think about issues on competing in a saturated market. Also, it would be worthwhile to generate creative solutions for the problems that Caffe Bene is now facing to broaden the practical perspective.

This study was intended to outline the characteristics of the food culture in the area of Kyungsangnamdo and its modernization by interpretation and analysis of the novel Toji, which was set in Hadong, Jinjoo in the area of Kyungsangnamdo in the early 20th century. The characteristics of the Kyungsangnamdo area's native dish during the Japanese ruling era in the latter half of the Choson dynasty are as follows. In the first part of the novel, which spans from 1897 to 1908, vegetable and grain food development can be seen in the area of Hadong, the interior plains of Kyungsangnamdo, where there is a typical farming village in the mountains. The second part of the novel, which spans from 1911 through 1917, includes some mentions of the properties of Kyungsangnamdo area's native dishes through the lens of emigrated Koreans living on Gando island. Gando island is in China, and is where Seohee, the heroine, escapes from her homeland and remains for a period of years. There is a unique type of seafood in the Gando area using fresh marine products, exactly the same as in the Kyungsangnamdo area. The third part of the novel spans 1919 through 1929, after Seohee returns to her own country and regains her house. There is a noticeable description of food culture in the area of Jinjoo in Kyungsangnamdo through the description of Seohee focusing on the education of her children. The well-described features of Jinjoo are boiled rice with soup of beef leg bones and Jinjoo bibimbob, with vegetables and a variety of foods using cod. Cod are caught in large quantities in Kyunjgsangnamdo, and cities in the area grow to medium size as the area became traffic-based. The fourth part of the novel spans from 1929 through 1938, and includes very detailed descriptions of characters and background locations. Salted fish combined with the wild ingredients of Mt. Jiri feature prominently in the Kyungsangnamdo's area descriptions. The fifth part spans from 1940 through 1945, and as the Japanese colonization era ends, the foods described in Kyungsangnamdo seem to develop the usage of soybean paste. With abundant fish and shellfish Kyungsangnamdo, the dishes that evolve to use soybean paste include mussel soybean paste soup, picked bean leaves in soybean paste, chaitgook - cold soup from soybean paste, and seolchigook used with seaweed and sea laver.

The purpose of this study was 1) to review communal housing in the UK, 2) to consider the policy implications for elderly communal housing in Korea. The research methods used were 1) literature review about communal housing and related policy in the UK 2) field survey in the UK 3) interpretative suggestion for the proper policy implication to develope communal housing for the elderly in Korea. Sheltered housing in the UK had been developed as communal housing for the elderly with special needs since the 1970s. The type of sheltered housing were category 1 and category 2. Very sheltered housing with more facilities and meal services was added in 1980s. Sheltered housing was evaluated as the most humanistic solution for older people in the UK in 1980s. Because of the policy of moving institutional care to community care, sheltered housing became less in demand because of more options for older people including being able to stay in their own home. So new completion of sheltered housing by registered social landlords reduced saliently. Sheltered housing already totalled over half million units in which 5% of all elderly over 65 still lived and a small quantity of private sector for sale schemes emerged in the 1990s. The reason why the residents moved to sheltered housing was for sociable, secure, and manageable living arrangements. In general the residents were satisfied with these characteristics but dissatisfied with the service charge and quality of meals, especially in category 2.5 schemes. The degree of utilisation of communal spaces and facilities depended on the wardens ability and enthusiasm. Evaluation of sheltered housing indicated several problems such as wardens duty as a \"good neighbour\" ; difficult-to-let problems with poor location or individual units of bedsittiing type with shared bathroom ; and the under use of communal spaces and facilities. Some ideas to solve these problems were suggested by researchers through expanding wardens duty as a professional, opening the scheme to the public, improving interior standards, and accepting non-elderly applicants who need support. Some researchers insisted continuing development of sheltered housing, but higher standards must be considered for the minority who want to live in communal living arrangement. Recently, enhanced sheltered housing with greater involvement of relatives and with tied up policy in registration and funding suggested as an alternative for residential care. In conclusion, the rights of choice for older people should be policy support for special needs housing. Elderly communal housing, especially a model similar to sheltered housing category 2 with at least 1 meal a day might be recommended for a Korean Model. For special needs housing development either for rent or for sale, participation of the public sector and long term and low interest financial support for the private sector must be developed in Korea. Providing a system for scheme managers to train and retrain must be encouraged. The professional ability of the scheme manager to plan and to deliver services might be the most important factor for the success of elderly communal housing projects in Korea. In addition the expansion of a public health care service, the development of leisure programs in Senior Citizens Centre, home helper both for the elderly in communal housing and the elderly in mainstream housing of the community as well. Providing of elderly communal housing through the modified general Construction Act rather than the present Elderly Welfare Act might be more helpful to encourage the access of general people in Korea. in Korea.
