The study examines the similarities of competitive strategy between fashion industry and high-tech industry through a case study of a Japanese maker. From the study, some implications are drawn for the Korean fashion industry. It is hoped that this, will help towards establishing a suitable competitive strategy for firms in this industry. In the fashion industry, the product life cycle is so short as to prompt a new product obsolete too quickly, and the extent of product differentiation is remarkably extensive compared to any other industry. Generally speaking, firms in this industry focus more of their resources on product development and marketing rattler than on production and they attempt to maneuver the speed when they are required to enhance their competitive edge. This is enabled through being, as one might expect, information- and technology- intensive as are high-tech industries. In this sense, that of the competitive strategy of a firm in fashion industry to be similar to high-tech industry. The Japanese firm Y has transformed itself a leading firm in fashion uniform segment. The firm could achieve this status by integrating each function needed for creating customer*s value, that is, product development, production and marketing within one Quick Response System. For this purpose, Y introduced a bundle of high-tech communication systems such as SPD, SDS, ATOM, NICS and so on. In this sense it can be said that Y was aware of what sort of competitive strategy was required in the industry. Implications for Korean firms is that, first, the magnitude of understanding the industry specific factors in establishing competitive strategy in the fashion industry, are speed, flexibility and systematic integration supported by high technology which are characteristic of high-tech industries. Secondly, as can be seen in the fact that Y emphasized logistics in its technological transformation, the significance of logistics control is a key to manipulating speed and flexibility in the industry. To sum up, those who have insight into above findings will be likely to keep their competitiveness in the industry not only in the Korean market but also in global market in the near future.

이 논문에서는 과학과 기술의 관계에 대해 기술은 응용 과학이라는 계층적 모델을 비판하고, 그 둘은 서로 독자적 영역을 가지면서 상호작용 한다는 상호작용 모델을 옹호한다. 상호작용은 모델에 의하면, 기술은 비록 과학으로부터 많은 지식을 빌려오지만 과학으로부터 오지않은 자신의 지식영역이 있다. 기술을 구성하는 여러 성분 중에서 특히 공학과학으로서의 기술에 중점을 두었고, 공학과학의 핵심을 설계에 있다는 것을 이야기 하고 공학설계의 특성에 관해 논의했다. 기술적 지식이 과학적 지식과 다른 것 중 하나는 기술적 지식의 변화 모델이 과학적 지식의 변화 모델과는 다르다는 것이다. 기술적 지식의 두 가지 중요한 모델인 쿤 방식의 모델과 변이-선택 모델을 논의하면서 두 모델의 약점을 이야기 했다. 과학과 기술의 상호과학적 지식의 작용은 '매개된 상호작용'이라는 모델을 제시했고 그 모델의 가능성에 대해 간단히 이야기 했다. 산업계의 연구는 과학과 기술 사이의 상호작용의 한 형태이다. 이 산업계의 연구를 통해서 과학-기술은 점점 구조화되고 자율성을 띈다. 과학자와 공학자는 인격적 주체자이기 보다는 단순히 산업연구 구조의 한 부분이 되어 버린다.

Purpose - In China, electric vehicle industry has been increased attention as a environmental friendly transportation to solve pollution problems, and still growing to solve a technological gap issues in automobile industry. Although the interest of electric vehicle is getting bigger, there are not many studies that showing consumers' intention to purchase an electric vehicle. Because of this phenomenon, this study tried to find the factors which can affect the purchase intention of electric vehicle. Research design, data, and methodology - Drawing on the Planned Behavior Theory(TPB), this study examined attitude toward the behavior, subjective norm of environmental protection, and the influence of economic benefits on purchase intention through survey. we measure 233 Chinese samples. Results - The results showed that attitude toward electric vehicles, subjective norms of environmental protection, and economic benefits had a significant effect on purchase intention. To be specific, the consciousness of environmental protection, economic considerations, product image and its characteristic are all considerable aspects from the standpoint of Chinese consumers. In addition, we found that the higher the age group, the weaker relationship between attitude toward electric vehicle and purchase intention. Conclusion - This study suggests that diverse factors related to the purchase intention of electric car in China market and Chinese consumers. Especially, economic benefit factors, which have a statistically significant and significant influence on the purchase intention of electric vehicles, are not significant variables in the existing electric vehicle research. This result is considered to be the result of the fact that the electric vehicle is not only an automobile having an environmentally friendly factor but also a product which makes it consider the economic situation. Put together, the results of this paper give us the theoretical basis for establishing an electric vehicle marketing strategy in the rapidly changing Chinese market. Also, this paper will provide new ventures for marketing and distribution strategies for Korean companies that are looking to expand into China.

PURPOSE. The mechanical and interfacial characterization of laser welded Co-Cr alloy with two different joint designs. MATERIALS AND METHODS. Dumbbell cast specimens (n=30) were divided into 3 groups (R, I, K, n=10). Group R consisted of intact specimens, group I of specimens sectioned with a straight cut, and group K of specimens with a $45^{\circ}$ bevel made at the one welding edge. The microstructure and the elemental distributions of alloy and welding regions were examined by an SEM/EDX analysis and then specimens were loaded in tension up to fracture. The tensile strength (TS) and elongation (${\varepsilon}$) were determined and statistically compared among groups employing 1-way ANOVA, SNK multiple comparison test (${\alpha}$=.05) and Weibull analysis where Weibull modulus m and characteristic strength ${\sigma}_0$ were identified. Fractured surfaces were imaged by a SEM. RESULTS. SEM/EDX analysis showed that cast alloy consists of two phases with differences in mean atomic number contrast, while no mean atomic number was identified for welded regions. EDX analysis revealed an increased Cr and Mo content at the alloy-joint interface. All mechanical properties of group I (TS, ${\varepsilon}$, m and ${\sigma}_0$) were found inferior to R while group K showed intermediated values without significant differences to R and I, apart from elongation with group R. The fractured surfaces of all groups showed extensive dendritic pattern although with a finer structure in the case of welded groups. CONCLUSION. The K shape joint configuration should be preferred over the I, as it demonstrates improved mechanical strength and survival probability.

Objective: The aim of this study was to investigate the technology trend on developing helmets based on the analysis of Korean, US, European and PCT patents. Background: The usage of the personal protective equipment such as the safety helmet would be essential for preventing injuries and reducing the severity of injuries depending on the type of activity and the exposed environment. Method: Database of WIPSON was used for searching the patents. The objects were the Korean, US, European and PCT patents registered or opened from January 2011 to December 2014. The keyword to investigate was helmet, and International Patent Classification (IPC) was used for investigating the technology trend of the patents. Results: The cases of US patents annually increased, but the cases of European patents decreased. US patents belonged to all sections but Korean and European patents and PCT patents did not. The largest number of IPC, to which four areas' patents belonged, was 'Headwear' and the second largest one was 'Hygiene'. In the subgroup level, the most common largest subgroups were 'Parts, details or accessories of helmets' and 'Masks, shields, or hoods for welders'. Korean patents had the lowest ratio of single_IPC at 11%, but the ratios of single_IPC for US and European patents were 52%, respectively. 'Human necessities', 'Mechanical engineering', 'Physics', and 'Electricity' were used as a single_IPC, but lower levels of 'Performing operations', 'Chemistry', 'Textiles' and 'Fixed constructions' were used as multi_IPC. Most main applicants had patents which belonged to 'Human necessities'. Conclusion: The cases of US patents annually increased unlike others. The common technologies for creating the helmet were Parts of helmets under Headwear and Shields for welders under Hygiene. Many Korean patents tended to be categorized as multi_IPC, different from others. Application: To know the technological characteristic of patents would be helpful to initial stage developers.

The purpose of this study suggest the fashion of communication for 21th century fashion. Especially, Memphis fashion have the possibility of communicating through objects. The results of this study are as follows : First, Memphis idea is to make design into a sophisticated, conscious instrument of communication. As the Memphis fashion points out : design is an extraordinary tool for communicating because its intrinsic characteristic is the fact that it is used and distributed anyway, even without communicating anything. The Memphis fashion is trying to connect design and industry to the broader culture within which fashion moves. Second, Using different materials provides not only new structural Possibilities. but - above all - new semantic and metaphoric possibilities, order modes of communication, another language, and even a change of direction, broadening of perspective, appropriation and digestion of new values and the concomitant rejection of traditional structures that renewal always Involves. The memphis fashion works on the fabric of contemporaneity (lurex yarn, latex, chrome metal and steel) and contemporaneity means computers, electronics, a new awareness of the body. mass exercise and tourism. Third, color in Memphis has never been an ideological vehicle. As with decoration it is born tilth the design, forming an integral part of the structure. It alters the objects molecules. It works as a mass, as an intrinsic feature of a certain form and volume. The Memphis fashion was realized the introduction of ultramodern science into such experimental and creative implementation as optical motive, brilliancy of colour of electronic medium in audition to metallic fabric and high technical synthetic fiber. A color tilth pop culture connotations that weaver between technological allusions and Mcdonald's.

Surface modifications are commonly utilized to adjust the properties of the titanium and its alloy surface to the specific needs of the medical applications, but there are disadvantages such as poor osteoconductive properties and low adhesion of bone cell to implant surface. In order to improve these disadvantages, changes in surface properties have an important effect on osseointegration during implantation. In this paper we applied new technological method for improving a unique surface modification using the characteristic of an electrolytic Solution. Thus, in the electrolyte containing NaF in Na2SO4, TiO2 nanoporous was uniformly formed, and HAp nanoparticles were electrodeposited around the TiO2 nanopores, but in the electrolyte containing NH4F in (NH4)H2PO4, the coarse protrusions including HAp nano particles were regularly deposited onto the TiO2 barrier layer. The surface characteristics and the distributed elements and have been investigated by EDS analysis, and ultra-fine structure of surface are carried out using FE-SEM. To investigate the behavior of the anion, the analysis of chemical states was performed by XPS, and the narrow spectrums for Ti2P, Ca 2p, and P 2p seems to be almost similar depending on the characteristics of the electrolyte solution respectively. In addition, Ca 2p spectrum could be resolved into two peaks for Ca 2p3/2 and 2p1/2 at 347.4 and 351.3 eV, which are related to hydroxyapatite. And, the P peak can also be deconvoluted into two peaks for P1/2 and P3/2 levels with binding energy 134.2 and 133.4 eV, respectively. From the result of soaking test, the apatite morphologys were well-formed onto the modified surface according to the different conditions.

As of today-half a century has passed after 1945, the liberation from Japanese imperialism-it's significant to introspect our culture. On the one hand our culture has succeeded due to the peculiar history, but on the other hand it hasn't. So to speak, it has gained in Quantity but lost in Quality. There are keen, international competition and exchange in the modern culture. So the Qualitive success of modern design depends on if it had an original character or not. According to Korean rapid industrialization, technological extence, and economic growth, the export has increased greatly, but package design hasn't been match for them. Korean expoters have been meeting with cutthroat competition in world market. Under these circumstances it's very important that we have a real understand and interest in our culture, we strengthen the competitive power of home products with good package design. This is our age of not home market but world market. We live in an age when design wins, so that we have to develop the good design native to Korea. Many designers have proposed their opinions with the characteristic designs, but it has been only a fragmentary and passive method. We must seek for the new method more positively. The effective and proper method resolves itself into the following four points. First, to understand Korean history and culture. Second, to have the exact grip of this economic situation. Third, to promote the national emotion. Fourth, in conclusion, to accord the package design with them. We cannot put off this task to overcome the cultural subordination, to place Korea on a firm cultural basis in the world, and to contribute to the cultural exchange of package design.

연잎효과는 연꽃의 잎에서 규명된 현상으로 표피세포에서 기원하는 미세구조에 의해 물방울이 잎 표면이나 내부조직에 침투하지 않고 경사면으로 흘러내리며 표면 위 먼지나 이물질을 함께 떨어지게 한다. 잎 표면을 항상 깨끗한 상태로 유지하는 자기정화 능력인 연잎효과에 대해서는 여러 영역에서 연구되고 다방면으로 응용되고 있으나 구조적인 측면에서 연잎을 생장단계별 또는 표피조직 부위별로 비교 조사한 연구는 거의 없는 실정이다. 이에 본 연구에서는 연잎과 줄기를 대상으로 생장단계별, 부위별 표피조직의 미세 표면구조를 연구하여 연잎효과 표면 특성을 조사하였다. 본 연구에서 조사된 연잎효과는 미세돌기와 왁스결정체가 발달한 잎의 상피조직에서만 나타나고, 왁스결정체만 발달한 하피 및 줄기의 표피조직에서는 확인되지 않았다. 이는 미세돌기의 발달이 연잎효과를 나타내는데 가장 중요한 요인이고, 왁스결정체가 돌기표면 위에 축적되면 연잎효과는 더 증가하는 것으로 밝혀졌다.
