We systematically reviewed the literature on the co-occurrence of squamous cell carcinoma (SCC) and Warthin's tumor (WT), thought to be quite rare, to help reduce misdiagnosis and improve treatment planning. For this systematic review, we searched for articles in the Web of Science and PubMed databases, analyzed relevant studies for forward and backward citations, and identified only articles reporting on the "co-occurrence" of WT and SCC. Of the 237 studies identified, 12 comprising 18 patients met the inclusion criteria, to which we added one study from our institution. Most WTs were associated with SCC in the parotid gland or cervical lymph nodes. Most patients (89.5%) underwent selective or radical neck dissection due to identification of lesions separate from the primary SCC. Despite its frequent co-occurrence with other neoplasms, WT in the parotid or cervical lymph nodes tends to be misdiagnosed as a metastatic node when SCC is observed as the primary tumor. Factors to consider in diagnosis and neck management include identification of an association other than growth or development by lymphangiogenesis and whether the patient is a smoker, a strong risk factor.

Due to the recent development of system semiconductors, technical innovation for the electric devices of the automobile industry is rapidly progressing. In particular, the electric device of automobiles is accelerating technology development competition among automobile parts makers, and the development cycle is also changing rapidly. Due to these changes, the importance of strategic planning for R&D is further strengthened. Due to the paradigm shift in the automobile industry, the Product-Technical Roadmap (P/TRM), one of the R&D strategies, analyzes technology forecasting, technology level evaluation, and technology acquisition method (Make/Collaborate/Buy) at the planning stage. The product-technical roadmap is a tool that identifies customer needs of products and technologies, selects technologies and sets development directions. However, most companies are developing the product-technical roadmap through a qualitative method that mainly relies on the technical papers, patent analysis, and expert Delphi method. In this study, empirical research was conducted through simulations that can supplement and strengthen the product-technical roadmap centered on the automobile industry by fusing Gartner's hype cycle, cumulative moving average-based data preprocessing, and deep learning (LSTM) time series analysis techniques. The empirical study presented in this paper can be used not only in the automobile industry but also in other manufacturing fields in general. In addition, from the corporate point of view, it is considered that it will become a foundation for moving forward as a leading company by providing products to the market in a timely manner through a more accurate product-technical roadmap, breaking away from the roadmap preparation method that has relied on qualitative methods.

Due to the rapid development of ICT, corporate business models quickly changed and because of the radical growth of IT technology, sequential or gradual survival has become difficult. Internet-based new businesses such as IT service companies are seeking for new convergence business models that have not existed before to create business models that are more competitive, but the economic efficiency of business models that were successful in the past is wearing off. Yet, as reaching the critical point where the platform value becomes extremely high for platforms via the Internet is happening at a much higher speed than before, platform-ization has become a very important condition for rapid business expansion for all kinds of businesses. This study analyzes the necessity of establishing platform business models in IT service planning and identifies their characteristics through case analyses of platform business models. The results derived features First, there is a need to ensure sufficient buyers and sellers, and second, platform business model should provide customers with distinctive value of the only platforms are generating. third, the common interests between platform-driven company and a partner, participants Should be existing. Fourthly, by expanding base of participants and upgrades, expansion of adjacent areas we must have a continuous scalability and evolution must be sustainable. While it is expected that the identified characteristics will cause tremendous impacts to the establishment of platform business models and to the graphing of service planning, we also look forward to this study serving as the starting point for the establishment of theories of profit models for platform businesses, which were not mentioned in the study, so that planners responsible for platform-based IT service planning will spend less time and draw bigger schemes in building planning drafts.

This study is empirically intended to put forward the modeling and process improvement measures for the SCM capability in small venture firms. The findings are summarized as follows. There were strategic alliance, technological development and centralization in the modeling of strategic planning for supply chain, not the least of which is strategic alliance, followed by centralization and technological development. There were routing scheduling, network integration and third party logistics outsourcing in decision making, not the least of which was network integration. There were customer service management, productivity management and quality management in management control, not the least of which was quality management. And there were order management choice, pricing demand, shipment delivery and customer management in transaction support system, not the least of which was order management choice. As for the above-mentioned findings, to maximize the SCM capability and operate the optimized process in small venture firms, the existing strategic alliances can optimize the quality management and stabilize the transaction support system through the network sharing and integration from the perspective of relevant organizational members' capability and process improvement. And the strategic linkage between firms can maximize the integrated capability of information system beyond the simple exchange relation between electronic data, achieving a differentiated competitive advantage. Consequently, the systematization and centralization for the maximization of SCM capability, including the infrastructure construction based on the system compatibility and reliability for information integration, should be preceded before the modeling of the integrated capability for optimum supply chain and the best process management in the smart era.

The spinal cord dose is the one of the limiting factor for the radiation treatment of the head ＆ neck or the thorax region. It is not an easy task to maintain the spinal cord dose below tolerance and to keep the clinically acceptable dose to the PTV in this region. To overcome this problem, the spinal cord partial block technique (PBT) with the dynamic Multi-Leaf Collimator (dMLC) has been developed. This technique is an extension of the conventional treatment planning. In the beginning the beam directions are selected as same as the conventional treatment planning to encompass the PTV, then the partial block are designed to shield the spinal cord. The plan comparisons between the conventional therapy plan and the PTB plan were performed to evaluate the validity of this technique. The mean dose and the dose volume histogram (DVH) were used as the plan comparison indices. A series of quality assurance (QA) was performed to guarantee the reliable treatment. The QA consisted of the film dosimetry for the verification of the dose distribution and the point measurements. The PBT plan generated better results than the conventional treatment plan and it was proved to be useful for the H＆N region.

Established in 2006 as the forward integration effort by Taesung Industry, the major cosmetic packaging company, TONYMOLY has phenomenally grown to one of the major cosmetic brand companies in the submarket called, 'one brand-shop' of cosmetic market since 2008, after overcoming the crisis of 'going out of business' in a couple of early years. Within a relatively short period of time, TONYMOLY's performances have dramatically improved in terms of metrics such as growth in sales revenue, the number of stores, the average sales per store, transaction value per customer, the number of monthly transactions, the number of membership-based customers, and overseas sales. In this case study, we have examined TONYMOLY's recent marketing activities which may explain the plausible reasons behind the substantial growth of a small but smart cosmetic company. Above all, the first key success factor of TONYMOLY would be found in its adherence to the clear philosophy of the customer value proposition and/or the differentiated position of TONYMOLY as a brand of providing value. Second, this brand concept of value was first penetrated and welcomed among the foothold customer target group of mid and late teens with appropriate products, while the target groups were later expanded into the age group of twenties along with expansion of relevant products. Third, its differentiation efforts have been concrete and meaningful by utilizing unique ingredients in its product development and marketing efforts, unique fun packaging, and continuously introducing new hit-selling products as well as managing steady-selling products. Fourth, TONYMOLY has been smart enough to use its limited marketing money efficiently and effectively in its marketing communication activities. Viral marketing, PPL, and concentrated media planning and execution turned out to produce effective and efficient market-based performances such as awareness, word-of-mouth, and sales. Lastly, the marketing leadership of CEO and top management, emphasizing communications and interactions, was confirmed in the relationship quality with and trust level of its franchisees and internal employees. These key success factors may explain the recent phenomenal market performances of TONYMOLY. Despite recent successes, the major issues are presented for TONYMOLY to consider for maintaining its sustainable advantages and growth. The first issue concerns TONYMOLY's choice of growth philosophy between product/brand-centric marketing and customer-centric marketing. The second challenging issue relates to how TONYMOLY can cope with 'growing pains' plausibly accompanied with the rapid growth.

This study was uncertaken to find an effective management modality for patients with hypertension. Patients 60years or older were selected for this purpose from a general hospital and a welfare center in Pusan and from a public health clinic in Cheju Island. During the month of October in 1984. the management modality for hypertension. the incurred medical expenses. and knowledge about the hypertension were analyzed and compared. The following results were obtained: 1. The a erage total medical expense per year was highest at the general hospital followed by the public health clinic and the welfare center. 2. It was found that the patients chose the public health clinic for its low medical cost. the welfare center for its proximity as well as for its low medical cost. and the general hospital for its quality medical services Also. the study has shown that the prescription of drugs was the major service provided by the public health clinic whereas the blood pressure measurement. the prescription of drugs. and family planning were the primary service offered by the welfare center. Drug prescription and blood pressure measurement were two of the most important services by the general hospital. 3. It was shown that the knowledge of hypertension was highnest at the welfare center whereas the management of hypertension was highest at the public health clinic. Based on above results and considering the chronic nature. it is believed that family awareness of the illness was one of the most important aspects for effective management of the hypertension for the elderly patients. In addition. the health care clinics at every level should come forward to execition of the educational programs and home nursing schomes for the effective management of the hypertension patients.
