  • Objective: Service industry has become the most important industry among various economic activities, as the percentage of service related industry in advanced nations is over 60% of their GDP and the percentage of service industry in South Korea, a traditional manufacturing nation, now takes up over 60% of the entire economy. Background: Such industry paradigm shift has changed consumers from those that simply purchased products into groups of people that evaluate the companies that manufacture products, thereby further intensifying competition among companies and increasing the importance of integrated communication between companies and consumers. However, the excessive existence of sub-identities that have been developed for integrated management of the existing corporate identities, as well as the undifferentiated general management strategies by companies are creating confusion not only for consumers but also for various corporate interest parties. In addition, service identity strategy has become the most important strategy than any other sub-identity strategies in forming corporate identity at the increased importance of corporate service in the era of service industry. However, the current domestic circumstance is that the concept of service identity has not been well established through specific related studies. Method: Accordingly, the existing academic and field studies on the corporate identity(CI), brand identity(BI) and product identity(PI) used for the communication with consumers were reviewed in this study to establish and summarize the concept of service identity(SI) that appeared at the service economization. Results: The purpose is to examine the kind of change that could be brought about by SI for the corporate integrated identity strategy developed through the existing corporate, brand & product image in order to present a new direct in corporate identity strategy according to the industry paradigm shift through a SI centered new corporate identity framework. Conclusion: For preparing the new era of service industry, the corporate integrated identity strategy must be integrate with concept of service identity and which is essential to differential from other companies. Application: The proposed concept and framework of service identity on this paper will help to understand and clearly define why service identity is important factor of the new idea of corporate identities.

  • The speed is one of the significant factors affecting accident occurrence. In particular, freeway accidents are highly associated with the speed because vehicles travel on the freeway at higher speed leading to greater potential of severer injury. Efforts attempting to relating speed with accident occurrence have not been significantly made in Korea. The objective of this study is to model the relationship between speed and accident rate on freeways. Loop detector data and accident data obtained from a stretch of Kyungboo freeway during the recent five years, 2005-2009, were used to establish the model. Multiple linear regression analyses showed that median, minimum and standard deviation of speed were contributing variables in the model. The statistical significance identified by the analyses supports the feasibility of the model in evaluating various transportation policies and operations strategies in terms of traffic safety.

  • This thesis intends to make a study on the effectiveness of Nursing Professors through perceptual psychological approach. Purpose of the Study Researches have been made relating teacher′s effectiveness measurement. However, they share a common defect that they have been done on the basis of superficial aspects of the problems aspects that can bi measured by general objective survey only, but this study is designed "to understand his behavior in terms of a human behaving and of a self as an instrument"-principle, based upon the Perceptual Psychology which puts more stress on the inner perception than on the external one. Method of the Study This thesis is based chiefly on the two sources : "Perceptual Orientation Scale"(Chunghoon Choy, 1971) which has been standardized on the basis of perceptual psychology and the question acres made by the researcher of this thesis and given to the 34 Nursing Professors in seoul and other country. Result of the Study The method of data operation by Pearson "r" asserts that there were distinct deep relation Between Perceptual orientation and fellow′s estimate, while a little relation among the estimate of a-administration, educational backgrounds and occupations but no relations the status of experiences. It can be concluded that the estimates between fellows working at "the same fields" have kept deep relations together on perceptual orientation which resulted from finding out a useful method to measure occupational effectiveness according to the perceptual field. Conclusion of the Study The personnel administration has been managed according to external flatus and not positive operation: on the other hand, this study holds, It shall be operated in accordance with the estimates by fellow, the "Preceptual Orientation Scale" for more positive ability. The study requires the following researches on the devoted professional occupations, such as medical doctors, teachers, nurses, etc. for the purpose of increasing their occupational effectiveness more scientifically.

  • In Korea, salt stress is one of the major problems limiting crop production and eco-environmental quality in greenhouse soil. The objective of this study was to evaluate the effectiveness of organic residues (Chinese milk vetch, maize stalk, rice straw, and rye straw) for reducing salt activity in greenhouse soil. Organic residues was incorporated with salt-accumulated soil (EC, 3.0 dS $m^{-1}$) at the rate of 5% (wt $wt^{-1}$) and the changes of electrical conductivity (EC) was determined weekly for 8 weeks under incubation condition at $30^{\circ}C$. The EC, microbial biomass carbon (MBC), and water soluble ions in soil was strongly affected by C/N ratio of organic residues. After 8 weeks incubation, the concentration of water soluble $NO_3{^-},\;Ca^{2+}$, and $Mg^{2+}$ was significantly decreased in organic residues having high C/N ratio (maize stalk, rice straw, and rye straw) incorporated soil compared to organic residues having lower C/N ratio (Chinese milk vetch) incorporated soil. The EC value in Chinese milk vetch incorporated soil was higher than control treatment. In contrast, maize stalk, rice straw, and rye straw amended soil was highly decreased the EC value compared to control and Chinese milk vetch applied soil after 4 weeks incubation. Our results indicated that incorporation of organic residues having high C/N ratio (>30) could reduce salt activity resulting from reducing concentration of water soluble ions.

  • Objective: To observe local and systemic toxicity after sustained-release 5-fluorouracil (5-Fu) implantation in canine peritoneum and para-aortic abdominalis and the changes of drug concentration in the local implanted tissue with time. Methods: 300 mg sustained-release 5-Fu was implanted into canine peritoneum and para-aorta abdominalis. Samples were taken 3, 5, 7 and 10 days after implantation for assessment of changes and systemic reactions. High performance liquid chromatography was applied to detect the drug concentrations of peritoneal tissue at different distances from the implanted site, lymphatic tissue of para-aortic abdominalis, peripheral blood and portal venous blood. Results: 10 days after implantation, the drug concentrations in the peritoneum, lymphatic tissue and portal vein remained relatively high within 5 cm of the implanted site. There appeared inflammatory reaction in the local implanted tissue, but no visible pathological changes such as cell degeneration and necrosis, and systemic reaction like anorexia, nausea, vomiting and fever. Conclusions: Sustained-release 5-Fu implantation in canine peritoneum and para-aortic abdominalis can maintain a relatively high tumour-inhibiting concentration for a longer time in the local implanted area and portal vein, and has mild local and systemic reactions. Besides, it is safe and effective to prevent or treat recurrence of gastrointestinal tumours and liver metastasis.

  • Uncertainties are unavoidable in engineering applications. In this paper we propose an alpha reliable multi-variable network design problem under demand uncertainty. In order to decide the optimal capacity enhancement, three performance measures based on 3E(Efficiency, Equity, and Environmental) are considered. The objective is to minimize the total budget required to satisfy alpha reliability constraint of total travel time, equity ratio, and total emission, while considering the route choice behavior of network users. The problem is formulated as the chance-constrained model for application of alpha confidence level and solved as a lexicographic optimization problem to consider the multi-variable. A simulation-based genetic algorithm procedure is developed to solve this complex network design problem(NDP). A simple numerical example ispresented to illustrate the features of the proposed NDP model.

  • Objective: To explore the application of multiplex nested methylated specific polymerase chain reaction (PCR) in the early diagnosis of epithelial ovarian carcinoma (EOC). Materials and Methods: Serum and fresh tissue samples were collected from 114 EOC patients. RUNX3, TFPI2 and OPCML served as target genes. Methylation levels of tissues were assessed by multiplex nested methylated specific PCR, the results being compared with those for carcinoma antigen 125 (CA125). Results: The serum free deoxyribose nucleic acid (DNA) methylation spectrum of EOC patients was completely contained in the DNA spectrum of cancer tissues, providing an accurate reflection of tumor DNA methylation conditions. Serum levels of CA125 and free DNA methylation in the EOC group were evidently higher than those in benign lesion and control groups (p<0.05). Patients with early EOC had markedly lower serum CA125 than those with advanced EOC (p<0.05), but there was no significant difference in free DNA methylation (p>0.05). The sensitivity, specificity and positive predicative value (PPV) of multiplex nested methylated specific PCR were significantly higher for detection of all patients and those with early EOC than those for CA125 (p<0.05). In the detection of patients with advanced EOC, the PPV of CA125 detection was obviously lower than that of multiplex nested methylated specific PCR (p>0.05), but there was no significant difference in sensitivity (p>0.05). Conclusions: Serum free DNA methylation can be used as a biological marker for EOC and multiplex nested methylated specific PCR should be considered for early diagnosis since it can accurately determine tumor methylation conditions.

  • The purpose of this study was to provide the guidance in more objective and proper clothing design and a strategy of fashion marketing from consumer sensibilities about adult women's town wear in un-limited circumstance. The specific objectives were 1) to investigate relationship between fashion sensibility and consumer sensibility of Good and Bad women's town wear, 2) to compare fashion sensibility with consumer sensibility of Good and Bad women's town wear, and 3) to investigate a dimension of Good and Bad women's town wear in fashion sensibility. Because they can affect estimators, the collected photos at shopping mall, department stores, and churches (S/S, F/W: April 28, 2004~May 1, 2005) were prepared removing face and background and attached on gray board. To investigate consumer sensibilities, the stimulus were 80 photos (40 for 'good', 40 for 'Bad'). The questionnaire consisted of bi-polar 25 pairs adjective scale of consumer sensibility was distributed 600 female (20's~40's) living in Busan (June 28, 2005~July 11, 2005). The data were analyzed by ANOVA, Regression analysis, and MDS. The results of practical study are summarized as follows. Fashion sensibility on the preference in Good and Bad women's town wear is closely related in 'want to buy-do not want to buy' and buying need is 'like-dislike'. For the fashion sensibility dimension at Good women's town wear, X axis showed from Young to Adult and Y axis showed from Hard to Comfortable following positioned design characters. For the fashion sensibilities dimension at Bad women's town wear, X axis showed from Young to Adult, Y axis showed from Normal to Unique, and Z axis showed from Heavy to Light following positioned design characters.

  • Korean medical journals were continuously published during the period of Japanese colonization of Korea. Various advertisements by herbal drugs manufacturers were in these journals, targeting Korean medical doctors or students who aspired to be Korean medical doctors. The advertisements varied from small ones to large-scale ads. At first these advertisements covered only dried herbs, but with time, they came to advertise various kinds of drugs. Advertisement of merchandise drugs brought many changes to the medical culture of Korea. Korean medical doctors who only prescribed dried herbs before began to prescribe merchandise drugs as well. When treating patients, they not only used Korean drugs but also actively prescribed merchandise drugs and western drugs, showing an advancement in treatment. As Korean medical doctors played the role of providers of merchandise drugs, herbal drugs manufacturers and Korean medical doctors seemed as sellers and consumers on the surface. However, they maintained a relationship where Korean medicine worked as the common denominator. Among merchandise drugs, Yoeng-so-hwan, Bi-jeon-go, and Myeol-dok-hwan were advertised often, and this shows that people at the time suffered mostly from digestive diseases, skin diseases, and sexually transmitted diseases. Herbal drugs manufacturers were business managers whose main objective was to make a good profit, but they consisted a part of Korean medical society. Like Korean medical doctors, they were anxious about the fall of Korean medicine. As a part of popularization of Korean medicine, they encouraged Korean medical doctors to treat patients using herbal drugs and merchandise drugs. This thought was reflected well in advertisements and Korean medical doctors made use of this thought well.
